TOUCH SENSOR OPERATED HAIR DRYER

TECHNICAL FIELD The invention relates to a hair dryer and touch sensor circuits which are used together for the operation of the dryer.

STATE OF THE ART

Hair dryers are commonly used at home and in hair salons for drying and shaping the hair.

The energy consumption of hair dryers and blow dryers is high and they cause noise pollution during their operation. And noise leads to discomfort in the environment in which they are being used.

Especially in hair care centers, the fact that more than one hair dryer is being run causes disturbing noise pollution, overheating and hygiene problems in the salon due to disturbing the accumulated dust particles on the ground. Also, due to high energy consumption values, hair dryers are considered among the foremost cost items of the business.

According to state-of-the-art, many solutions have been found for the hair dryers that run loudly. The utility model application No. TR 2014/01876, which proposes one of the above-mentioned solutions, discloses the new techniques for a low- noise blower (hair dryer). The said utility model and the invention disclosed therein relates to the elimination of noise by replacing the motor and changing the design of hair dryers. However, the said invention has not provided a proper solution to the noise problem of hair dryers and the noise problem persists during the hair drying process and also the energy consumption cost has increased accordingly. Also, when the said hair dryers are preferred to be used in hair dressing centers such as hair salons, barber shops etc. where more than one person is cutting hair, the hairdresser using the device has to keep it in one hand while his/her other hand tries to shape the hair. If s/he desires to give shape to hair with both hands, the hair dryer should hang on a device on/over an apparatus or an assistant should hold the device for a while. The hairdresser does not turn off the hair dryer and keeps it running during the period when s/he hangs it on a hook with a view to shaping the hair with both hands. When the hair dryer is hanged on the hook or held between his/her legs or under the arm or left on the bench, the air blowing outlet of the device is positioned perpendicular to the ground. When held or left with the said angles, the hair dryer causes the accumulated dusts, hairs etc. to hover, circulate and fly around, and when it is kept between the legs or under the arm of hairdresser or left on the bench, it causes not only noise pollution but also scattering of materials and equipment on the bench and blowing the pieces of hair around the place. All these disadvantages may result in heart disease, inhalation problems, allergic bacterial infection, spread of severe infectious diseases as well as hearing problems due to the noise both for the customers and staff in the salon.

Due to the aforementioned causes, the efforts to reduce or eliminate the noise problem of hair dryers have failed to achieve the desired goal so far. Therefore, a touch sensor operated hair dryer according to the invention has been developed so as to reduce energy consumption costs and also prevent undesired dust, hairs etc. on the ground from blowing around the salon.

The invention, which is proposed for the solution of the above-mentioned problems is a hair dryer that can be operated with a touch sensor and relay switch. Thanks to the system according to the invention, it does not require the turning on and off of the device consistently, which means that it can stop running when it is hung on a hook, kept between the legs or under the arm or left on the bench for a while, in other words, when there is no hand contact between the device and user, it stops operating. The said invention is a unique product with cutting-edge technology and it is operated with a sensitive touch sensor equipped with a relay switch. The touch sensor driving relay switch is also used for different devices other than hair dryer.

The said invention prevents the above-mentioned problems and also avoids spreading diseases by providing a healthy working environment, and extends the service life of devices and reduce the electricity cost by avoiding the unnecessary running of device.

DESCRIPTION OF INVENTION The objective of the invention is to reduce energy consumption of hair dryers by temporarily stopping the operation of the motor without fully turning it off during the short-time processes (combing, shaping etc.) while blowing, setting or drying the hair.

Another objective of the invention is to prevent health problems that possibly occur in hair designing centers such as hair salons, barber shops etc. due to hovering or blowing of accumulated dust particles or pieces of hair around the air arising out of the air blown by frequently used hair dryers.

Another objective of the invention is to avoid noise pollution of hair dryers.

Another objective of the invention is to avoid overheating in the environment caused by the hair dryers.

Another objective of the invention is to extend the service life of the device by avoiding the unnecessary running of it.

Another objective of the invention is to enable the hairdressers to easily operate it when they hang the device over an apparatus or keep it between their legs or under their arm or put on the bench in hair designing centers such as hair salons or barber shops. Another objective of the invention is to minimize the radiation being exposed during the operation of hair dryers.

DESCRIPTION OF THE INVENTION

The said invention relates to a touch sensor operated hair dryer and consists of on/off and speed control switches (1), heat control switch (2), relay contact tip (3), sensor board (4), detection tip (5), resistor (6), motor (7), upper cover (8), lower cover (9), inner part of upper cover (10), conductive element (11), hand (12), shunt cable (13) and connection cable (14).

The said invention is composed of the on/off and motor speed control switches (1) that provide the required voltage and current to the device and sensor board (4), enable the device to stop during the on-position, and to run at the short-circuit position. The said invention also consists of the heat control switch (2) that adjusts the degree of heat.

The said invention consists of the relay contact tip (3) that enables the operation of the device by transferring the inflow current from the grid to the system.

The invention consists of the sensor board (4) whose function is to make the detection tip (5) ready for hand contact when the grid voltage is supplied. The invention also consists of the detection tip (5) that triggers the operation when contacted by hand; the said tip comes from the sensor board (4) and is positioned inside the upper cover (8).

The said invention consists of chrome nickel steel resistor (6) that provides required heat to device.

The invention also consists of a motor (7) whose function is to suck sufficient air and heat it through the resistor and then blow it outside.

The said invention is comprised of conductive elements (11) positioned in the circular area of the upper cover (8) and the middle section of the handle (12). The invention also consists of a shunt cable (13) that enables the contact of the conductive element (11) positioned in the circular area of the upper cover (8) with the conductive element (11) positioned inside the handle (12) and upper cover (8).

The said invention consists of the connection of the cable (14) connected to the detection tip (5) of the sensor board (4) following the connection of the conductive element (11) positioned in the circular area of the upper cover (8) and the conductive element (11) positioned inside the handle (12) of the upper cover (8) with the shunt cable (13).

If the user grips the device from the handle or center body during the time when the on/off and motor speed control switch (1) is in the short-circuit position, which means ready-to-operate, as shown in Figure 5, the detection tip (5) of the sensor board (4) triggers the relay after hand contact and the system starts to operate when the relay contact tip (3) turns to the shirt-circuit position.

If the user puts the device on the bench, hangs it on the waist bag or keeps the hair dryer between the legs or under the arm during the time the on/off and motor speed control switch (1) is in the short-circuit position, which means ready-to- operate, as shown in Figure 4, the system stops running by turning the relay contact tip (3) into the on-position because the detection tip (5) of the sensor board (4) does not sense any hand contact.
