TECHNICAL FIELD

[0001] Embodiments of the present disclosure generally relate to the repair of electronic devices, and to the repair of electronic devices that have been rendered at least partially inoperative due to moisture intrusion.

[0002] Embodiments of the present disclosure also generally relate to apparatuses and methods for drying electronics and non-electronic objects, particularly devices that are subject to high- humidity conditions of the human body such as hearing amplification electronics, smart watches, blood sugar detection meters, and electronic rings.

BACKGROUND OF THE DISCLOSURE

[0003] Electronic devices are frequently manufactured using ultra-precision parts for tight fit-and- finish dimensions that are intended to keep moisture from entering the interior of the device. Many electronic devices are also manufactured to render disassembly by owners and or users difficult without rendering the device inoperable even prior to drying attempts. With the continued miniaturization of electronics and increasingly powerful computerized software applications, it is commonplace for people today to carry multiple electronic devices, such as portable electronic devices. Cell phones are currently more ubiquitous than telephone land lines, and many people, on a daily basis throughout the world, inadvertently subject these devices to unintended contact with water or other fluids. This occurs daily in, for example, bathrooms, kitchens, swimming pools, lakes, washing machines, or any other areas where various electronic devices (e.g., small, portable electronic devices) can be submerged in water or subject to high humid conditions. These electronic devices frequently have miniaturized solid-state transistorized memory for capturing and storing digitized media in the form of phone contact lists, e-mail addresses, digitized photographs, digitized music and the like.

[0004] Moreover, with the advent of the miniaturization of wireless transceiver electronics there has been an explosion of new types of devices that aid human beings in everyday life through the transmission of data. There has been significant strides in smart phone headsets, hearing aids, smart watches, and finger rings which are worn on the human body and all subjected to constant humidity bombardment, often in excess of 95% from the natural perspiration process that maintains human homeostasis.

[0005] In the case of hearables residing in the ear canal and over the ear, the desire is to have these devices weigh as little as possible and be durable. The combination of durability and light weight requires the assembly of these devices using the strongest plastics (e.g. ABS, polycarbonate, acrylic) which all have the undesired property of being hygroscopic, or, readily absorbing water. This property causes significant moisture uptake within hearables due to the constant evaporation of perspiration with the device resting on the skin.

[0006] In addition, rechargeable batteries are the preferred method of powering such devices and are often encased within the device which is constantly absorbing water. This leads to unintentional battery shorts and the premature draining of the batteries.

[0007] Some wearable devices, such as hearing aids, use sophisticated micro-mechanical electronic mechanisms (MEMs) and diaphragms for the microphones. Heat and vacuum pressure can have a deleterious effect on these components and therefore, a new type of drying system is required. SUMMARY OF THE DISCLOSURE

[0053] FIG. 1 shows a perspective front view of a first exemplary embodiment of a dryer 10, with chamber lid 14, drying chamber subassembly 16, lower housing 18, and start-stop switch 15. In some embodiments, start stop switch 15 can be a tactical feel membrane switch with integrated LEDs for dryer condition visual feedback (e.g. calibration, regeneration, or drying modes). Chamber lid 14 and drying chamber subassembly 16 are mated together through twist-lock features 17.

[0054] As best shown in FIG. 2, chamber 20 utilizes chamber O-ring 24 to seal against chamber lid 14 of FIG. 1. Bypass seal plate 22 is firmly attached to the interior bottom of chamber 20 using ultrasonic welding, plastic glue, or equivalent. Gearmotor 25 which is mounted to chamber 20 is depicted with air valve and sensor subassembly 26 together with pressure-generating device and moisture-absorbing substance subassembly 28.

[0055] Referring now to FIG. 3, drying chamber subassembly 16 of FIG. 1 is shown with bypass seal plate 22, gearmotor mounting pocket 30, pinion gear 32, and valve pinion rack 34. Pinion gear 32 is permanently mounted to output shaft of gearmotor 25 of FIG. 2 and is mated with valve pinion rack 34. Gearmotor 25, when powered, can provide rotational force onto valve pinion rack 34 and therefore translate valve pinion rack 34 into rotational movement.

[0056] FIG. 4 which is a bottom perspective view of drying chamber subassembly 16 of FIG. 2 is shown with center pivot point 40, negative pressure plenum 44 and positive pressure plenum 42. Negative pressure plenum 44 together with positive pressure plenum 42 provide air flow means to chamber 20 of FIG. 2. As best shown in FIG. 5, chamber 20 is depicted with bypass channel 50, input port 53, and output port 54. Bypass channel 50 incorporates a raised circumferential edge 56 to allow bypass sealing plate 22 of FIG. 3 to seal against this feature. Conversely, input port 53 and output port 54 are recessed below raised circumferential edge 56 to allow unrestricted air flow. Raised support ribs 58 provide support features for bypass sealing plate 22 to rest on without impeding air flow to input port 53 and output port 54.

[0057] As best shown in FIG. 6, chamber 20 is depicted from the bottom side showing bypass channel ports 62 together with input port 53 and output port 54 of FIG. 5. Position location magnet or optical signal reflection rivet 66 is permanently mounted into chamber 20 and provides a magnetic field or optical reflective surface for position sensing. Bypass channel ports 62, input port 53 and output port 54 are all recessed to permit the mounting of sealing O-rings 65. Sealing O-rings 65 are slightly proud of recessed ports to provide a compliant air-tight seal to any planar surface resting on them with some level of force applied on the planar surface. Non-ported areas 67 and 69 allow for airflow between bypass channel ports 62 and input port 53 and output port 54. [0058] Referring now to FIG. 7, rotary valve 70 is depicted with valve pinion rack 34 of FIG. 3. Rotary valve 70 captivates sealing O-rings 71 against sensor control board 72 and is fastened together with fasteners 76. Sensor control board 72 contains hall effect or optical reflective sensors 78 A, 78B, and 78C and output port humidity sensor 74 and input port humidity sensor 73. Through holes 75 surround input port humidity sensor 73 and output port humidity sensor 74 such that airflow can impinge onto humidity sensors 73 and 74 and flow through input port 53 and output port 54 of FIG. 6. The compressive force imparted onto sealing O-rings 71 through fasteners 76 compressing rotary valve 70 and sensor control board 72 results in an air tight seal between sensor control board 72 and rotary valve 70. Although not shown, the underside of rotary valve 70 can have recessed pockets for sealing O-rings 71 similar to the recessed pockets of FIG. 6.

[0059] As best shown in FIG. 8, the underside of sensor control board 72 is mechanically attached to rotary valve 70 using fasteners 76. Center through hole 82 is used to provide a rotational center point for air valve and sensor subassembly 26. FIG. 9 depicts air valve and sensor subassembly 26 mounted to chamber 20 via captivating fastener 91 and spring 95. Captivating fastener 91 can be a screw, nut, or press-on captivation washer. Spring 95 provides necessary force to air valve and sensor subassembly 26 to allow control sensor board 72 to seal against sealing O-rings 65 of FIG. 6. Pinion gear 32 which mates with valve pinion rack 34 provides a moment about axis 92 and develops rotary motion 93. Valve input port 94 and valve output port 96 allows a means to impinge on input port humidity sensor 73 and output port humidity sensor 74 of FIG. 7.

[0060] FIG. 10A depicts air valve and sensor subassembly 26 in the two and eight o-clock position (111) such that bypass channel 50 of FIG. 5 which is sealed using bypass seal plate 22 of FIG. 3 provides airflow across input port humidity sensor 73, through bypass channel 50, and across output port humidity sensor 74. This position is controlled by the rotation of gearmotor 25 of FIG. 2, pinion gear 32 and valve pinion rack 34 of FIG. 3 and calibration hall effect sensor or optical reflective sensor 78A which is aligned with position location magnet or optical signal reflection rivet 66 of FIG. 6 and electronically locates air valve and sensor subassembly 26 under computer control. Airflow path 101 of FIG. 10B is now engaged via pressure-generating device 105 which pushes air through moisture-absorbing substance 107. Airflow path 101 produces calibration humidity response curves 109 depicted in FIG. 10C which allows for baseline humidity calculation values for input and output humidity sensors 73 and 74 of FIG. 7. Due to airtight, closed loop drying, these readings are stored in microcontroller memory as a baseline micro-environment calibration starting point and therefore desired drying ending point for closed loop device drying. [0061] FIG. 11 A depicts air valve and sensor subassembly 26 in the three and nine o-clock position (112) which is the desiccant regeneration position. In the three and nine o-clock position, the air valve and sensor subassembly 26 are positioned such that through holes 75 of FIG. 8 are directly in-between bypass channel ports 62, input port 53 and output port 54 of FIG. 6. This provides an air valve and sensor subassembly 26 position which disengages flow to the airtight chamber altogether. Air flow path 102 depicted in FIG. 1 IB flows through non-ported exhaust channel 67 and non-ported input channel 69 of FIG. 6 and between bypass channel ports 62 and input port 63 and output port 64. Air flows across input port humidity sensor 73, through non-ported exhaust channel 67 and non-ported input channel 69 and across output port humidity sensor 74. The three and nine o-clock position is controlled by regen hall effect sensor or optical reflective sensor 78B which is aligned with position location magnet or optical signal reflection rivet 66. Again referring to FIG. 1 IB, Airflow path 102 is now engaged via pressure-generating device 105 which pushes moisture laden air through moisture-absorbing substance 107 being baked by perforated desiccant heater 108. Airflow path 102 ensures moisture laden air being sampled on input port humidity sensor 73 response is compared to output port humidity sensor 74 response and continues a baking sequence until input port humidity sensor 73 response converges to output port humidity sensor 74 response.

[0062] FIG. 12A depicts air valve and sensor subassembly 26 of FIG. 9 in the four and ten o-clock position (120) such that input port 53 of FIG. 6 provides airflow across input port humidity sensor 73 of FIG. 7, through chamber 20 of FIG. 2 interior, across output port humidity sensor 74 of FIG. 7 and output port 54 of FIG. 6. This position is controlled by hall effect sensor or optical reflective sensor 78C which is aligned with position location magnet or optical signal reflection rivet 66. Airflow path 103 of FIG. 12B is now engaged via pressure-generating device 105 which pushes air through moisture-absorbing substance 107. As the airflow flows across the desiccant, the humidity of the airflow drops below 20% relative humidity. This closed loop drying path 103 produces a low-humidity environment at room ambient temperature and allows for consistent and reliable moisture uptake in any device within chamber 20 interior. The airflow on Airflow path 103 has a flow rate of at least 2 CFM and no more than 4 CFM . The combination of the flow rate, low relative humidity, and room ambient temperature maximizes evaporation of water. Any moisture entrained inside in any device within chamber 20 interior will migrate out through the device’s plastic due to the hygroscopic quality of plastic. In some embodiments, the air volume within chamber 20 interior may be decreased while the static pressure generated by pressuregenerating device 105 is increased to further expedite the moisture uptake.

[0063] Airflow path 103 of FIG. 12B produces humidity response curves 110 depicted in FIG. 12C which allows for moisture laden air being sampled on output port humidity sensor 74 response to be compared to input port humidity sensor 73 response and continues a drying sequence until output port humidity sensor 74 response converges to input port humidity sensor 73 response saved in memory during calibration. These response curves are compared to baseline response curves 109 of FIG. 10C which allows a drying endpoint to be calculated.

[0064] As best shown in FIG. 13, pressure-generating device and moisture-absorbing substance subassembly 28 is depicted in an exploded view. Pressure-generating device 130 utilizes seals 131 to provide an airtight seal against input header 135 and desiccator grill 132. Desiccator regenerative heater 134 is captivated between desiccator pouches 133 and held together by desiccator grill 132 and output header 136. Input header 135 utilizes suction plenum 44 to draw air in from drying chamber subassembly 16 of FIG. 1, while output header 136 incorporates pressure plenum 42 to push air into drying chamber subassembly 16 of FIG. 1. Suction plenum 44 and pressure plenum 42 utilize o-rings for air-tight sealing purposes and snap features to mechanically couple to valve input port 44 and valve output port 96 of FIG. 9. Once assembled, pressure-generating device and moisture-absorbing substance subassembly 28 is shown in FIG. 14 as an assembled stack utilizing fasteners 144 to compress input header 135 and pressure output 136 thus providing an airtight subassembly.

[0065] FIG. 15 describes the control code algorithms which allow the calibration, desiccant regeneration, and drying phases of the dryer. The process is started with moving the valve to the calibration position of FIG. 10, sampling the humidity sensors 73 and 74 of FIG. 7, and if the humidity is greater than 20%, moving the valve to the desiccant regeneration position of FIG. 11. During calibration, the humidity threshold may be adjusted to compensate for temperature increases in the humidity sensors 73 and 74 in order to increase the accuracy of humidity readings. Once position of FIG. 11A is achieved, the desiccator regenerative heater 134 of FIG. 13 is powered and the desiccant bakes out the moisture which has been entrained. Humidity sensors are constantly sampled until the humidity drops below 20% which signifies the desiccant is dried to a point whereby it can now produce an ultra-dry micro environment. In some embodiments, the dryer can be configured to maintain a different humidity level for purposes of maintaining products for which humidity level is critical for optimal usage, such as tobacco products, medical marijuana, and leather products like baseballs. Then, air valve and sensor subassembly 26 of FIG. 9 is moved to the position in FIG. 12A and humidity sensors 73 and 74 are once again constantly sampled. Once the humidity values are within +/- 1% of each other, the closed loop is not taking up any additional moisture and the device is dry.
