Thin hand washing device with automatic drying function

The invention relates to a hand washing device, in particular to a person who has a drying function and is light in size and does not occupy a space.

Press, the hand washing table is the most frequently used bathroom equipment, and the general hand washing table is designed to avoid the splashing, and most of them are designed to protrude outward, so that it has a groove for receiving tap water. However, when the sink of this form is installed in a space-saving mass transit vehicle or a mobile toilet, the prominent form takes up most of the space. If the hand dryer is added, it can not only be used inside the toilet. The space is greatly reduced, which may cause inconvenience to users or cleaners.

In order to improve the above-mentioned deficiency, the Republic of China Patent No. 222060 discloses a "three-machine integrated automatic washing mobile phone" which is automatically controlled by a body, a water supply device, a cleaning liquid supply device, a dryer device, a drain device and a program. The circuit is composed. When the user puts his hands into the cleaning chamber, the sensor disposed on the body senses the message and transmits it to the automatic control circuit. After receiving the message, the automatic control circuit can be programmed. Control washing mobile phone for automatic water supply, automatic cleaning solution, water supply and drying.

Republic of China Patent Bulletin No. 398270, which discloses a "hand dryer" The structure is improved, which is provided with a hand washing water pipe system, a supply air circulation system and a circuit control system in the main body. When the user puts his hand into the water tank to detect the sensor switch provided on the main body, the hand washing is started. The water pipeline system performs the watering action, and after the preset time, the air supply circulation system is closed and restarted to perform the drying operation, and the construction and maintenance procedures can be simplified by modular control.

The Republic of China Patent Publication No. M408638 discloses a "faucet structure with a blowing function" which is designed in the faucet body to be an independent air outlet channel different from the water outlet pipe, and the air outlet channel is provided with an air outlet at the faucet body and The air inlet of the air device is taken off at the other end, so that when the user places the hand in the air outlet position, the air blowing device can automatically start to send the hot air to achieve the effect of washing hands and drying.

The Republic of China Patent Bulletin No. M430495 discloses a "automated hand washing station" which is equipped with a water level detector in the water tank, and a cleaning liquid unit, a water supply unit, a drying unit and a photographing unit above the water tank. The photographing unit can photograph the cleaning liquid unit, the water supply unit and the drying unit and output a photographing image, and the photographing screen can be automatically controlled by the image recognition software of the control unit to automatically control the cleaning liquid unit, the water supply unit, and the drying. The dry unit is activated.

Converting and outputting a distance signal to the interval of reflection, preferably, the distance sensor 13 is inductively sensed by infrared rays, and the sensing path A is located between the receiving slot 102 and the water tank 103; the circuit control system 14 is electrically Connected to the distance sensor 13 and output a control signal after receiving the distance signal; the control valve 15 is electrically connected to the circuit control system 14 and has a push rod 151 which is passed through the water outlet device. The positioning hole 113 of the column 112 can be used to drive the push rod 151 to advance or retreat after receiving the control signal, thereby controlling the through hole 111 of the water outlet device 11 to be opened or closed; the hot air fan 16 is placed in the corresponding water tank in the housing. 103 air outlet 106 position, and Electrically connected to the circuit control system 14, after receiving the control signal, the hot air blower 16 is driven to blow the hot air from the air outlet 106; the angle adjusting device 17 is electrically connected to the circuit control system 14 and connected to the rotating shaft of the movable door panel 12. 122. After receiving the control signal, the rotating shaft 122 is driven to pivot the movable door panel 12.

Next, referring to FIG. 4 , a schematic diagram of the assembly of the present invention is completed. After the hand washing device 1 is assembled on the wall surface, the water outlet device 11 and the movable door panel 12 are received and received in the receiving slot 102 of the body 10 . In the water tank 103, the entire hand washing device 1 is brought into a flat state. When the user approaches the hand washing device 1 and enters the sensing path A of the distance sensor 13 (refer to Figures 5-6), the sensing signal is reflected by the hand and is calculated to output a distance signal. The distance signal is transmitted to the circuit control system 14, and the circuit control system 14 outputs a control signal to the angle adjusting device 17 and the control valve 15 after receiving the distance signal to drive the angle adjusting device 17 to control the rotating shaft 122 of the pivoting movable door panel 12. Pivoting, the flap 121 of the movable door panel 12 is leveled, and an open space is surrounded between the water tank 103 and the movable door panel 12, and the control valve 15 is driven to push the push rod 151 forward (as shown by the arrow in FIG. 5) The column 112 of the water discharge device 11 is displaced in the chute 105, and the through hole 111 of the water discharge device 11 is opened. At this time, the tap water enters the water inlet 104 via the water outlet pipe 3 and is discharged by the water discharge device 11 The through hole 111 flows out for the user to achieve the effect of cleaning the hand. The waste water flowing into the water tank 103 flows out through the through hole 107 at the bottom of the water tank 103 into the drain line 2 connected to the drain port 101.

The circuit control system 14 transmits the control signal to the control valve 15 and the hot air fan 16 (refer to FIG. 7) after a certain time, according to the set requirement, to drive the control valve 15 to pull the push rod 151 back (such as the arrow in the figure). The cylinder 112 of the water discharge device 11 is displaced in the sliding slot 105, and the through hole 111 of the water outlet device 11 is closed, and the hot air blower 16 is driven to blow hot air from the air outlet 106 for hand drying. action.

Please refer to FIG. 8 , which is a schematic diagram of the folding of the present invention. The circuit control system 14 can detect obstacles in the sensing path A according to the setting requirements, such as after a certain time or the distance sensor 13 in the sensing path A. When the control signal is transmitted to the hot air blower 16 and the angle adjusting device 17, The hot air blower 16 is closed and the driving angle adjusting device 17 controls the pivoting shaft 122 of the pivoting movable door panel 12 to pivot, so that the flap 121 of the movable door panel 12 is folded and closed to close the water tank 103 (shown by an arrow in the figure).
