RELATED APPLICATIONS

[0001] The present application claims benefit of priority of U.S. Provisional Application Serial No. 62/933,674 , filed November 11, 2019, which is incorporated herein by reference.

FIELD

[0002] The present disclosure relates generally to exhaust fans.

BACKGROUND

[0003] Exhaust fans can be used to pull odors, fumes, and moisture from a space, such as a bathroom or other environment (e.g., industrial space). For instance, an exhaust fan can be activated (e.g., turned on) when a user is taking a shower. In this manner, moisture accumulating in the air due to the running shower water can be removed from the bathroom. However, since exhaust fans are often manually switched on and off by the user, instances may occur in which the user forgets to activate the exhaust fan prior to running the shower water. In such instances, moisture accumulating in the air due to the running shower water can be deposited on one or more surfaces (e.g., floor) of the bathroom.

DETAILED DESCRIPTION

[0014] Reference now will be made in detail to embodiments, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the embodiments, not limitation of the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments without departing from the scope or spirit of the present disclosure. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that aspects of the present disclosure cover such modifications and variations. [0015] Example aspects of the present disclosure are directed to an exhaust fan for a space, such as a bathroom or industrial environment. The exhaust fan can be used to draw air within the space through a vent of the exhaust fan and can expel the air at a location other than the space. [0016] For example, a fan motor of the exhaust fan can be activated to drive rotation of one or more fan blades of the exhaust fan to remove moisture that accumulates within the air while a shower within the space is being used. As another example, the fan motor can be activated to remove odors present within the space. In this manner, the exhaust fan can ventilate the air within the space as needed. As will be discussed below in more detail, the exhaust fan can be configured to monitor one or more parameters of the air within the space and activate the fan motor when an actual value for the one or more parameters of the air deviate from a setpoint for the one or more parameters.

[0017] Although aspects of the present disclosure are discussed with reference to an exhaust fan for a bathroom, those of ordinary skill in the art, using the disclosures provided herein, will understand that the exhaust fans can be used in other spaces (e.g., industrial spaces) without deviating from the scope of the present disclosure.

[0018] In some implementations, the exhaust fan can include one or more sensors configured to detect the one or more parameters of the air within the space. For example, the one or more sensors can include a humidity sensor configured to detect a relative humidity of the air within the space. Alternatively or additionally, the one or more sensors can include an air quality sensor (e.g., gas sensor) configured to detect presence of odors or fumes within the air. In this manner, operation of the fan motor can be controlled based, at least in part, data obtained from the one or more sensors to provide improved ventilation of the space.

[0019] In some implementations, one or more control devices onboard the exhaust fan or remote relative to the exhaust fan can be configured to obtain data from the one or more sensors (e.g., humidity sensor, air quality sensor, etc.) and can be further configured to determine a shower is ready for a user. For instance, the one or more control devices can be configured to determine the shower is ready when the one or more sensors (e.g., humidity sensor) detect an amount of moisture within the air that is indicative of presence of steam within the space. The one or more control devices can be further configured to provide a notification to indicate the shower is ready. For instance, the one or more control devices can provide the notification to a handheld computing device (e.g., smartphone, tablet, etc.) associated with the user. [0020] In some implementations, the exhaust fan can include one or more microphones. The one or more microphones can be configured to detect one or voice commands associated with a user-request to control operation of the exhaust fan. More specifically, the user request can be associated with controlling one or more components of the exhaust fan. In this manner, operation of the exhaust fan can be controlled without requiring a user to provide a manual input at an input device (e.g., in-wall switch). In some implementations, the one or more voice commands can be associated with controlling operation of the fan motor. For instance, the one or more voice commands can be associated with toggling power to the fan motor.

[0021] In some implementations, the fan motor of the exhaust fan can be configurable in a plurality of different modes and/or can be a variable speed fan motor. In particular, the fan motor can rotate the fan blades of the exhaust fan at a different speed when configured in each of the plurality of modes. In such implementations, the one or more voice commands can be associated with selection one of the plurality of modes as a selected mode of operation for the fan motor to adjust a speed at which the fan motor rotates the fan blades of the exhaust fan.

[0022] In some implementations, one or more control devices of the exhaust fan can be configured to automatically adjust a speed of the fan motor in response to receiving voice commands so that the voice commands are more audible over the sound associated with operation of the fan motor. For instance, a speed of a variable speed motor can be reduced when the one or more voice commands are detected via the one or more microphones.

[0023] In some implementations, the one or more voice commands can be associated with a user-request to play a song or radio station via one or more output devices (e.g., speakers ) of the exhaust fan. In this manner, a user can request a song or radio station to be played over the one or more output devices while the user is taking a shower.

[0024] In some implementations, the exhaust fan can include one or more motion sensors. The one or more motion sensors can detect motion of a user within the space. In this manner, the one or more motion sensors can detect presence of the user within the space. In implementations in which the exhaust fan is positioned directly above the shower in the space, the one or more motion sensors can be used to detect presence of the user within the shower. In this manner, the data from the one or more motion sensors can be used to determine whether the user has slipped or fallen in the shower. For instance, one or more control devices can be configured to determine the user has fallen or slipped in the shower when a predetermined amount of time lapses since the one or more motion sensors last detected motion of the user.

[0025] In some implementations, the one or more control devices can obtain additional data to confirm whether the user has, in fact, slipped or fallen within the shower. For instance, the one or more control devices can obtain data from the one or more microphones since the one or more microphones can detect audible sounds (e.g., shower water running) or verbal cues (“Help”) indicative of the user falling or slipping in the shower. When the one or more control devices confirm the user has slipped or fallen in the shower, the one or more control devices can be configured to provide a notification to indicate the user slipped or fell in the shower. For instance the one or more control devices can be configured to provide the notification to one or more person included in a notification tree.

[0026] In some implementations, the exhaust fan can include a first communication interface and a second communication interface. The first communication interface can facilitate communication between the exhaust fan and one or more peripheral devices over a first network (e.g., local network). The second communication interface can facilitate communication between the exhaust fan and one or more remote computing devices over a second network (e.g., external network) that is different than the first network. In this manner, the exhaust fan can facilitate communication between the one or more peripheral devices on the first network and the one or more computing devices on the second network. In some implementations, the one or more control devices can be configured to communicate with remote devices over a single network and/or direct peer-to-peer communication.

[0027] Example communication technologies and/or protocols can include, for instance, Bluetooth low energy, Bluetooth mesh networking, near-field communication, Thread, TLS (Transport Layer Security), Wi-Fi (e.g., IEEE, 802.11), Wi-Fi Direct (for peer-to-peer communication), Z-Wave, Zigbee, HaLow, cellular communication, LTE, low-power wide area networking, VSAT, Ethernet, MoCA (Multimedia over Coax Alliance), PLC (Power-line communication), DLT (digital line transmission), etc. Other suitable communication technologies and/or protocols can be used without deviating from the scope of the present disclosure.

[0028] In some implementations, the one or more control devices can be configured to provide one or more control signals over the local network to control operation of one or more peripheral devices on the local network based, at least in part, on data obtained from the sensors or microphones of the exhaust fan. For example, the one or more control devices can provide one or more control signals over the local network to toggle power to a light source that is located within the space and separate from the light source of the exhaust fan and/or the light indicator of the exhaust fan. More specifically, the one or more control devices can provide the one or more control signals over the local network to the light source in response to obtaining data from the one or more motion sensors that is indicative of presence of the user within the space. It should be appreciated that the light source that is separate from a light source of the exhaust fan can be located at any suitable location within the space. For instance, in some implementations, the light source can be associated with a vanity mirror located in the space. Alternatively, the light source can be associated with a lighting fixture located in the space.

[0029] In some implementations, the exhaust fan can be in communication with a remote computing device over the external network. More specifically, the remote computing device can be a hand-held computing device (e.g., smartphone, tablet, etc.) associated with the user. In such implementations, the one or more control devices of the exhaust fan can be configured to access a mobile application implemented on the hand-held computing device to obtain data indicative of an alarm clock setting. More specifically, the alarm clock setting can be indicative of a time of day at which the user intends to wake up.

[0030] Based on the data indicative of the alarm clock setting, the one or more control devices can be configured to control operation of one or more heating elements operable to heat a floor of the space. More specifically, the one or more control devices can be configured to activate the one or more heating elements a predetermined amount of time before the alarm on the mobile computing device goes off. In this manner, the floor of the first space can be heated before the user enters the space.

[0031] In some implementations, the exhaust fan can include one or more light indicators, such as a light ring and/or a light bar. For instance, the exhaust fan can include a ring of light emitting diodes (LEDs) or other light sources. In some implementations, the light ring can be controlled in response to various actions, such as responsive to voice commands. For instance, in some implementations, the light ring can be controlled to be displayed in response to a voice command received via the one or more microphones. Once the voice command is completed, the light ring can be turned off or no longer illuminated. In some implementations, various different animation sequences can be displayed in response to detection of different voice commands or other user input. For instance, a circular animation configured to mimic a spinning circle can be displayed in response to detection of a voice command.

[0032] In some implementations, the exhaust fan can include a night light. The night light can provide ambient lighting at night. The color and/or brightness of the night light can be specified as part of settings associated with the exhaust fan (e.g., via an application implemented on a user device).

[0033] The exhaust fan according to the present disclosure can provide numerous technical benefits. For instance, the one or more microphones of the exhaust fan allow a user to control operation of the exhaust fan without having to provide a manual user-input at an input device (e.g., in-wall switch). In addition, the exhaust fan can act as a bridge between one or more peripheral devices on a local network and one or more computing devices on an external network. In this manner, the exhaust fan can obtain data from a user device (e.g., smartphone, tablet, etc.) on the external network and control operation of the one more peripheral devices on the local network.

[0034] Referring now to the FIGS., FIG. 1 depicts an exhaust fan 100 according to example embodiments of the present disclosure. As shown, the exhaust fan 100 can be disposed within a recess defined by a ceiling 110 separating a first space 112 (e.g., positioned beneath the ceiling 110) from a second space 114 (e.g., positioned above the ceiling 110). In some implementations, the first space 112 can be a bathroom having a shower 116 and a toilet 118. It should be appreciated, however, that the exhaust fan 100 according to the present disclosure can be used in any suitable space requiring ventilation.

[0035] Although the exhaust fan 100 is depicted as being located within ceiling 110 such that the exhaust fan 100 is located at or near a middle of the first space 112, it should be appreciated that the exhaust fan 100 can be positioned at any suitable location. For instance, in some implementations, the exhaust fan 100 can be positioned within the ceiling 110 such that the exhaust fan 100 is located directly above the shower 116 located in the first space 112. Alternatively, the exhaust fan 100 can be positioned within the ceiling 110 such that the exhaust fan 100 is located directly above the toilet 119 located in the first space 112.

[0036] As shown, the exhaust fan 100 can include a plurality of fan blades 130 (shown in phantom). Furthermore, the exhaust fan 100 can further include a fan motor 140 (also shown in phantom). The fan motor 140 can be configured to receive an input power from a power source, such as an alternating current (AC) power source or a direct current (DC) power source. Furthermore, the fan motor 140 can be operatively coupled to the fan blades 130. In this manner, the fan motor 140 can convert the input power into mechanical energy needed to drive rotation of the fan blades 130.

[0037] As the fan blades 130 rotate, air 200 within the first space 112 can be drawn through a vent 150 (FIG. 2) of the exhaust fan 100. In some implementations, the exhaust fan 100 can be activated while a user is taking a shower. In this manner, moisture (e.g., water vapor) accumulating in the air 200 due to the shower water 117 can be removed from the first space 112 and thereby prevent fog from forming within the first space 112. Alternatively or additionally, the exhaust fan 100 can be activated to remove fumes or odors within the air 200 and associated with use of the toilet 118 by the user. In this manner,

[0038] In some implementations, the exhaust fan 100 can expel the air 200 into the second space 114. For instance, a second exhaust fan (e.g., attic fan) positioned within the second space 114 can be configured to draw air 200 within the second space 114 through a vent of the second exhaust fan and expel the air 200 at a location that is different than the first space 112 and the second space 114. In alternative implementations, the exhaust fan 100 can expel the air 200 into one or more air ducts (not shown) disposed within the second space 114. In this manner, the air 200 can be routed through the one or more air ducts and expelled at a location that is different than the first space 112 and the second space 114.

[0039] In some implementations, the fan motor 140 can be a configurable in a plurality of different modes. The fan motor 140 can be configured to rotate the fan blades 130 at a different speed when configured in each of the plurality of modes. For instance, in some implementations, the plurality of modes can include a first mode (e.g., low), a second mode (e.g., medium), and a third mode (e.g., high). When the fan motor 140 is configured in the first mode, the fan motor 140 can rotate the fan blades 130 at a first speed. When the fan motor 140 is configured in the second mode, the fan motor 140 can rotate the fan blades 130 at a second speed that is faster than the first speed. When the fan motor 140 is configured in the third mode, the fan motor 140 can rotate the fan blades 130 at a third speed that is faster than the first speed and the second speed. It should be appreciated that the fan motor 140 can be configurable in more or fewer modes. [0040] In some implementations, the exhaust fan 100 can include a light source 160 operable to illuminate the first space 112. It should be appreciated that the light source 160 can include any suitable type of light source. For instance, in some implementations, the light source 160 can include an array of light emitting diodes (LEDs). Alternatively or additionally, the light source 160 can be a dimmable light source.

[0041] In some implementations, operation of the exhaust fan 100 can be controlled via a control system 170. More specifically, the control system 170 can include a wall-switch that can be manipulated to selectively couple the fan motor 140 to the power source. In this way, the control system 170 ca be used to selectively activate (e.g., turn on) or deactivate (e.g., turn off) the fan motor 140 to control rotation of the fan blades 130. Furthermore, in some implementations, the control system 170 can be configured to control operation of the light source 160 of the exhaust fan 100. For instance, the control system 170 can be used to selectively activate or deactivate the light source 160.

[0042] Referring now to FIG. 3, components of the exhaust fan 100 are depicted according to example embodiments of the present disclosure. As shown, the exhaust fan 100 can include one or more sensors 210 configured to detect one or more parameters of the air 200 (FIG. 1) within the first space 112 (FIG. 1). In some implementations, the one or more sensors 210 can include a humidity sensor configured to detect a relative humidity of the air 200 within the first space 112. Alternatively or additionally, the one or more sensors 210 can include a gas sensor configured to detect odors within the first space 112.

[0043] The exhaust fan 100 can include one or more microphones 220 operable to detect audible sounds occurring within the first space 112. For instance, the one or more microphones 220 can detect one or more voice commands associated with a user-request to control operation of the exhaust fan 100. In this manner, operation of the exhaust fan 100 can be controlled without requiring the user to provide a manual-input at an in-wall power switch located within the first space 112.

[0044] In some implementations, the user-request can be associated with activating (e.g., turning on) or deactivating (e.g., turning off) the fan motor 140. Furthermore, in implementations in which the fan motor 140 is configurable in the plurality of different modes, the user-request can be associated with selecting one of the plurality of modes as a selected mode of operation for the fan motor 140 to adjust (e.g., increase, decrease) a speed at which the fan motor 140 rotates the fan blades 130 (FIG. 1) of the exhaust fan 100.

[0045] It should be appreciated that any suitable type of noise-cancellation technology (e.g., active noise control, passive noise control) can be incorporated into the exhaust fan 100 to improve detection of the one or more voice commands spoken by the user to implement the user- request associated with controlling operation of the exhaust fan 100.

[0046] In some implementations, the exhaust fan 100 can include one or more motion sensors 230. The one or more motion sensors 230 can be configured to detect presence of a user within the first space 112. Furthermore, in implementations in which the exhaust fan 100 is positioned within the ceiling 110 (FIG. 1) such that the exhaust fan 100 is positioned directly above the shower 116 (FIG. 1) located within the first space 112, the one or more motion sensors 230 can be used to detect occurrence of a user slipping or falling within the shower 116.

[0047] It should be appreciated that that the one or more motion sensors 230 can include any suitable type of sensor configured to detect motion of an object (e.g., person). For instance, in some implementations, the one or more motion sensors 230 can include a passive infrared sensor.

[0048] In some implementations, the exhaust fan 100 can include one or more heating elements 232. The one or more heating elements 232 can be configured to heat air that is directed into the first space 112 via a blower 234 of the exhaust fan 100. The blower 234 can be configured to direct air into the first space 112 via the vent 150 of the exhaust fan 100. In some implementations, the one or more heating elements 232 can be positioned between the vent 150 and the blower 234 such that the air directed by the blower 234 passes over the one or more heating elements 232 prior to exiting the exhaust fan 100 via the vent 150 thereof.

[0049] In some implementations, the exhaust fan 100 can include one or more output devices 236 configured to emit audio data. For instance, the one or more output devices 236 can include one or more speakers. In some implementations, audio data (e.g., music, talk radio, etc.) can be output via the one or more speakers in response to the one or more microphones 220 detecting one or more voice commands associated with a user-request to play audio data.

[0050] In some embodiments, the exhaust fan 100 can include an indicator light 238. For instance, the exhaust fan 100 can include a ring of light emitting diodes (LEDs) or other light sources. In some embodiments, the indicator light 238 can be controlled in response to various actions, such as responsive to voice commands. For instance, in some embodiments, the indicator light 238 can be controlled to be displayed in response to a voice command received via the one or more microphones. Once the voice command is completed, the indicator light 238 can be turned off or no longer illuminated. In some embodiments, various different animation sequences can be displayed in response to detection of different voice commands or other user input. For instance, a circular animation configured to mimic a spinning circle can be displayed in response to detection of a voice command.

[0051] As shown, the exhaust fan 100 can include one or more control devices 240. The one or more control devices 240 can be configured to control operation of one or more components of the exhaust fan 100. For instance, the one or more control devices 240 can be configured to provide one or more control signals associated with controlling operation of the fan motor 140. For instance, the one or more control signals can be associated with activating (e.g., turning on) or deactivating (e.g., turning off) the fan motor 140. Alternatively, the one or more control signals can be associated with configuring the fan motor 104 in one of a plurality of modes of operation of the fan motor 140 to adjust (e.g., increase, decrease) a speed at which the fan motor 140 rotates the fan blades 130 (FIG. 1). Furthermore, in implementations in which the exhaust fan 100 includes the light source 160, the one or more control devices 240 can be configured to provide one or more control signals associated with controlling operation of the light source 160. [0052] In some implementations, the one or more control devices 240 can be configured to obtain data indicative of one or more parameter of the air 200 (FIG. 1) within the first space 112 via the one or more sensors 210 of the exhaust fan 100. The one or more control devices 240 can be configured to process the data and control operation of the fan motor 140 based, at least in part, on the data. For instance, the one or more control devices 240 can be configured to activate (e.g., turn on) the fan motor 140 when the data indicates a relative humidity of the air 200 within the first space 112 is greater than a setpoint for the first space 112. Furthermore, in some implementations, the one or more control devices 240 can be configured to operate the fan motor 140 until additional data obtained from the one or more sensors 210 of the exhaust fan 100 indicates the relative humidity of the air 200 within the first space is at or below the setpoint for the first space 112.

[0053] As discussed above, the fan motor 140 can, in some implementations, be configurable in a plurality of different modes. In such implementations, the one or more control devices 240 can be configured to determine one of the plurality of modes as a selected mode of operation for the fan motor 140 based, at least in part, on a time of a day when the one or more control devices 240 determine the relative humidity of the air is above the setpoint for the first space 112. For instance, if the one or more control devices 240 determine the relative humidity of the air within the first space 112 is above the setpoint during the early morning hours (e.g., 10 PM to 6 AM), the one or more control devices 240 can configure the fan motor 140 in a mode in which the fan motor 140 rotates the fan blades 130 at a slower speed compared to every other mode of the fan motor 140. In this manner, noise associated with operation of the fan motor 140 can be reduced during the early morning hours.

[0054] Alternatively, if the one or more control devices 240 determine the relative humidity of the air within the first space 112 is above the setpoint during another portion of the day, such as the afternoon (e.g., 12 PM to 5 PM), the one or more control devices 240 can configure the fan motor 140 in a mode in which the fan motor 140 rotates the fan blades at a faster speed compared to every other mode of the fan motor 140. In this manner, the excess moisture in the air can be more quickly removed from the first space 112 such that the relative humidity returns to a value that is at or below the setpoint.

[0055] In some implementations, the one or more control devices 240 can be configured to obtain data indicative of presence of a user within the shower 116 (FIG. 1) located within the first space 112. The one or more control devices 240 can be further configured to determine the user has slipped or fallen within the shower 116 when a predetermined amount of time lapses since the one or more motion sensors 230 last detected presence of the user within the shower 116.

[0056] In some implementations, the one or more control devices 240 can obtain data from the one or more microphones 220 to confirm whether or not the user has, in fact, slipped or fallen in the shower 116. For instance, the one or more control devices 240 can be configured to confirm the user has slipped or fallen in the shower 116 when the predetermined amount of time lapses since presence of the user was last detected and the one or more microphones 220 detect audible sounds indicative of shower water running or verbal cues (e.g., “Help”). In such implementations, the one or more control devices 240 of the exhaust fan 100 can be configured to provide a notification to indicate the user slipped or fell in the shower. For instance the one or more control devices 240 can be configured to provide the notification to one or more person included in a notification tree. It should be appreciated that the notification tree can be stored at any suitable location. For instance, in some implementations, the notification tree can be stored in memory associated with the one or more control devices 240 of the exhaust fan 100.

[0057] In some implementations, the one or more control devices 240 can be configured to obtain audio data indicative of one or more voice commands detected by the one or more microphones 220 of the exhaust fan 100. As discussed above, the one or more voice commands can be associated with a user-request to control operation of the exhaust fan 100. In some implementations, the one or more control devices 240 can be configured to process the one or more voice commands locally to determine the user-request. Furthermore, the one or more control devices 240 can be further configured to provide one or more control signals to the fan motor 140 and/or the light source 160 depending on the user-request.

[0058] In alternative implementations, the one or more control devices 240 can be configured to provide the audio data indicative of the one or more voice commands to a remote computing device (e.g., server, cloud computing device, etc.) for processing. Furthermore, the remote computing device can be configured to provide one or more wireless signals to the one or more control devices 240 of the exhaust fan 100. The one or more control devices 240 can be configured to demodulate the one or more wireless signals to obtain data indicative of the user- request and can be further configured to provide one or more control signals to the fan motor 140 and/or the light source 160 based, at least in part, on the data indicative of the user request.

[0059] In some implementations, the exhaust fan can include a first communication interface 250 and a second communication interface 252. The first communication interface 250 can facilitate communication between the exhaust fan 100 and one or more peripheral devices on a local network. The second communication interface 252 can facilitate communication between the exhaust fan 100 and one or more remote devices on an external network. In this manner, the exhaust fan 100 can facilitate communication between the one or more peripheral devices on the local network and the one or more remote devices on the external network.

[0060] Referring now to FIG. 4, a system 300 for controlling operation of one or more peripheral devices 310 on a local network 320 within the first space 112 is provided according to example embodiments of the present disclosure.
