It is the figure which showed direction Y2. As shown in FIG. 7, by setting the angle difference between R1a and R2 to 10 ° to 40 °, a sufficient space can be provided between the hand washing position and the detection position by the washing liquid discharge sensor 21. It becomes difficult for human hands to enter the detection range of the discharge sensor 21.

FIG. 8 is a schematic diagram illustrating a state in which the emission unit 211 of the cleaning liquid discharge sensor 21 is disposed at a distance L from the discharge port 12 in the water discharger 10 in the hand washing apparatus 1 according to the present embodiment.

In the present embodiment, the emission part 211 that is provided on the front end side of the cleaning liquid discharge sensor 21 and emits emitted light such as infrared rays is disposed on the back side of the water discharge port 12 in the water discharger 10.
As described above, the greater the angle difference between R1a and R2, that is, the greater the sensor angle R2 of the cleaning liquid discharge sensor 21, the more difficult it is for a human hand to enter the detection range of the cleaning liquid discharge sensor 21 during hand washing.

When a person brings his hand close to the water discharger main body 10 a and a human hand enters the detection range of the water discharge sensor 11, a detection signal is transmitted to the water discharge control unit 16 by the water discharge sensor 11.

Receiving the control signal, the electromagnetic valve 15 opens the valve and supplies water to the water discharger main body 10a. The water supplied to the water discharger main body 10 a is discharged from the water discharge port portion 12.
When a person finishes washing his hands and the human hand is no longer within the detection range of the water discharge sensor 11, a control signal is similarly transmitted to the electromagnetic valve 15 by the water discharge control unit 16 that has received the detection signal from the water discharge sensor 11. Then, the solenoid valve 15 performs the valve closing operation, the water supplied to the water discharger main body 10a is shut off, and the water discharged from the water discharge port 12 is stopped.

Next, the operation of the cleaning liquid discharger 20 according to the present embodiment will be described with reference to FIG.
When a person brings his hand close to the cleaning liquid discharger body 20 a and a human hand enters the detection range of the cleaning liquid discharge sensor 21, the cleaning liquid discharge sensor 21 transmits a detection signal to the cleaning liquid discharge control unit 28. The cleaning liquid ejection control unit 28 that has received the detection signal transmits the control signal to the cleaning liquid pump 25 and the air pump 27. The cleaning liquid pump 25 that has received the control signal supplies the cleaning liquid stored in the cleaning liquid tank 24 by being fed to the cleaning liquid discharger main body 20 a through the cleaning liquid supply pipe 23. Similarly, the air pump 27 that has received the control signal supplies air to the cleaning liquid discharger main body 20 a through the air supply pipe 26. The cleaning liquid and air supplied to the cleaning liquid discharger body 20a are mixed and discharged as bubbles from the tip of the discharge port portion 22 connected to the discharge port.

According to the hand-washing apparatus 1 which concerns on this embodiment demonstrated above, there exist the following effects.
In the hand-washing apparatus 1 according to the present embodiment, the sensor direction Y2 of the cleaning liquid discharge sensor 21 in the cleaning liquid discharger 20 is inclined below the discharge direction X1a of water or hot water discharged from the water discharge port 12 in the water discharger 10. Configured. This makes it difficult for a person to enter the detection range of the cleaning liquid discharge sensor 21 when the water discharge operation is performed by the water discharger 10, that is, when the hand is washed, so that it is possible to prevent malfunction of the cleaning liquid discharger 20 during hand washing. . Moreover, since the detection ranges of the respective sensors of the water discharger 10 and the cleaning liquid discharger 20 can be prevented from overlapping, individual control of these devices is possible, and a control unit can be provided individually. In addition, since the malfunction can be prevented with a simple device configuration, the cost can be reduced.

Further, in the hand washing apparatus 1 according to the present embodiment, the emission unit 211 from which the emission light from the cleaning liquid discharge sensor 21 is emitted is arranged on the back side of the water discharge port 12 of the water discharger 10. This makes it difficult for a human hand to enter the detection range of the cleaning liquid discharge sensor 21 during hand washing without tilting the sensor direction of the cleaning liquid discharge sensor 21 so much, thereby ensuring ease of use of the cleaning liquid discharger 20 and hand washing. The malfunction of the cleaning liquid discharger 20 can be prevented.

Moreover, in the hand-washing apparatus 1 which concerns on this embodiment, when the inclination angle of the sensor direction with respect to the horizontal direction of the washing liquid discharger 20 is R2, and the inclination angle of the discharge direction X1a with respect to the horizontal direction of the water discharger 10 is R1a, The angle difference from R1a was 10 ° to 40 °. Thereby, since it can prevent more reliably that a human hand enters into the detection range of the cleaning liquid discharge sensor 21 at the time of hand washing, the malfunction of the cleaning liquid discharger 20 at the time of hand washing can be more reliably prevented.

Moreover, in the hand washing apparatus 1 according to the present embodiment, the water discharge control unit 16 that controls the water discharger 10 and the cleaning liquid discharge control unit 28 that controls the cleaning liquid discharger 20 are provided separately. Thereby, even when it is desired to add a new device to the hand-washing device 1 or to repair one device, it is not necessary to replace the entire control unit, so that the cost for facility expansion and repair can be reduced.

Further, the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the hand-washing apparatus 1 according to the present embodiment, the water discharger 10 and the cleaning liquid discharger 20 are described as having a wall that is fixed to the wall in FIG. It may be one with a fixed base.

In the above embodiment, the plurality of cleaning liquid discharge devices 20 are configured to receive the supply of the cleaning liquid from the single cleaning liquid tank 24. However, the present invention is not limited to this, and the single cleaning liquid discharge device is a single cleaning liquid. You may comprise so that supply of the washing | cleaning liquid may be received from a tank.

In the above embodiment, the cleaning liquid discharge device 20 is configured to include the air supply pipe 26 that supplies air for forming bubbles of the cleaning liquid. However, the present invention is not limited to this, and the cleaning liquid discharge apparatus 20 is an air supply pipe. 26 may be omitted.
