The operation and effects of the above-described respective structures will be described.

In the hand wash device 100 according to the embodiment of the present invention, when the automatic mode is selected, the controller 170 detects the insertion of the hand into the input port 111 by the body sensor 171, The water supply valve 141 is opened and the water supply pump 140 is operated for a preset time (approximately 5 seconds) to spray the washing water through the washing unit 130. [

At the same time, the controller 170 opens the cleaning agent valve 151 to spray the cleaning agent in the cleaning part 130 and operates the cleaning agent pump 150 for a predetermined time (approximately 5 seconds) to spray the cleaning water and the cleaning agent together .

The washing water and the cleaning agent supplied to the washing unit 130 are supplied to the first nozzle unit 131, the second nozzle unit 132 and the third nozzle unit 133 by the water distributor 143 and the cleaning / And the fourth nozzle unit 134, respectively, so that the hands can be cleaned by spraying washing water and a cleaning agent on both sides of each hand.

On the other hand, when the washing water and the cleaning agent are injected in the washing section 130 for a predetermined time, the controller 170 stops the operation of the water supply pump 140 and the detergent pump, And only the washing water is sprayed from the washing section 130 for a predetermined time (approximately 10 seconds).

At this time, the controller 170 stops the operation of the cleaning agent pump 150 and blocks the cleaning agent valve 151 in order to cut off the supply of the cleaning agent from the cleaning agent pump.

When the washing water is sprayed for a preset time, the controller 170 stops the operation of the water supply pump 140, blocks the water supply valve 141 to shut off the water supply to the washing water, For about a predetermined period of time (about 10 seconds) to spray dry air through the cleaning section 130 to dry the wet hands by the wash water.

Here, when the drying blowing fan 160 is operated, the heater 165 installed in the drying blowing fan 160 also operates to spray the heated dry air through the cleaning part 130.

When the drying and blowing fan 160 stops after the operation for a predetermined time, all the operations are ended and the operation is switched to the standby state.

On the other hand, when the user operates the operation panel 179, the controller 170 controls the water supply pump 140 to be set in advance (for example, The controller 170 activates the cleaning agent pump 150 only for a predetermined period of time to operate the cleaning section 130 so that the cleaning agent pump 150 is operated only for a predetermined period of time to spray the cleaning water through the cleaning section 130, The controller 170 turns the operation of the heater 165 on or off to provide the heated dry air to the cleaner 130 or the unheated The drying air can be supplied to the cleaning unit 130. [

When the air blowing button is operated, the controller 170 operates the drying blowing fan 160 for a predetermined time only to spray the drying air for a preset time in the washing section 130, have.

On the other hand, when the temperature detected by the temperature sensor 175 is equal to or higher than a preset temperature, the controller 170 determines that the heater 165 has overheated, and transmits the determined information to the outside through the wireless communication module 177 Can be informed.

In addition, the controller 170 may receive contamination information from the contamination detecting sensor 173 and inform the outside of the contaminated information through the wireless communication module 177.

For example, when the contamination detection sensor 173 is an ammonia detection sensor, when the ammonia detection sensor senses ammonia which causes malodor, the controller 170 notifies the outside of the occurrence of the malodor through the wireless communication module 177 If the water level sensor detects the water level of the washing water and the cleaning agent flowing into the drain tank 120, it is determined that the drainage tank 120 has been drained. In this case, It is possible to inform the outside that clogging has occurred.

Accordingly, since the hand wash dryer 100 according to the embodiment of the present invention can spray the washing water and the cleaning agent together and spray dry air, it is possible to dry the hands together with the washing, It can be installed in a place where the faucet is difficult to install and the hand can be easily cleaned.

Further, by spraying the cleaning agent and the washing water from the first nozzle unit 131 to the fourth nozzle unit 134 on both sides of each hand put into the inlet 111, the hands can be cleaned more cleanly.

In addition, a contamination detection sensor 173 is installed, and a wireless communication module 177 is installed, so that an external manager can take quick action due to contamination.

In addition, since the ultraviolet sterilizing lamp is installed to prevent the growth of bacteria, the opening and closing cover 113 can easily perform maintenance, and the detergent container 155 can be detachably attached to the detergent container 155 The cleaning agent can be easily charged.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
