In the conventional hand washing apparatus, a faucet-shaped fitting or a shower head is used as a cleaning liquid discharge fitting having a cleaning liquid discharge port, and the cleaning liquid is simply discharged from the cleaning liquid discharge port. If a faucet-shaped bracket is used,
The cleaning liquid is discharged in a single column, and when a shower head is used, the cleaning liquid is discharged in a plurality of columns distributed in a circular cross-sectional area.

In the conventional hand washing apparatus, when the hand is configured to be able to dry the hand, a drying air outlet for blowing out drying air is provided separately from the washing liquid outlet, and the drying air outlet is provided. A high-pressure air supply unit such as a turbo fan that supplies high-pressure air to the air outlet is provided.

[0005]

However, in the conventional hand washing apparatus, as described above, a faucet-shaped fitting or a shower head is used, and the washing liquid is simply discharged from the washing liquid discharge port. In order to remove hand stains in a short period of time, the user must perform hand-rubbing washing by rubbing both hands while the cleaning liquid is being discharged, and cannot perform hand washing with a simple operation. Was.

In the conventional hand washing apparatus, as described above, the cleaning liquid is merely discharged from the cleaning liquid discharge port. Therefore, when the supply pressure of the cleaning liquid is low, the discharge pressure of the cleaning liquid is low. As a result, it was not possible to remove hand stains in a short time.

Further, in the conventional hand washing apparatus, as described above, the washing liquid is simply discharged from the washing liquid discharge port, so that a large amount of the washing liquid is required in order to sufficiently clean the hands. And was uneconomical.

Further, in the conventional hand washing apparatus, as described above, when the hand is configured to be dried,
Since the drying air outlet was provided separately from the cleaning liquid outlet, the installation space was increased and the cost was unavoidable.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hand washing apparatus that allows a user to clean his / her hands with a simple operation in a short time.

It is another object of the present invention to provide a hand washing apparatus capable of increasing the discharge pressure of the washing liquid and removing hand stains in a short time even when the supply pressure of the washing liquid is low.

Another object of the present invention is to provide a hand-washing apparatus capable of saving a cleaning solution.

According to the first aspect, the cleaning liquid or the mixture of the cleaning liquid and the air is jetted in a sheet shape along the plane intersecting the direction in which the user's hand is extended. The hand can be cleaned in a short time by simply performing a simple operation of pulling out and inserting the hand back and forth without performing hand-rubbing washing or the like of rubbing both hands.

[0015] A hand washing apparatus according to a second aspect of the present invention comprises:
In the hand-washing device according to the first aspect, a width of the cleaning liquid or the mixture injected in the sheet shape at a hand-extending position is a width that covers both palms arranged side by side.

When the width is determined as in the second aspect, the cleaning liquid or the mixture is applied to both hands as a whole by simply inserting and removing the hand in the front-rear direction without moving the hand in the left-right direction. For this reason, according to the second aspect, it is possible to clean the hands in a short time only by performing a simpler operation, which is preferable. Note that the width of the cleaning liquid or the mixture injected at the hand at the position where the hand is ejected in a sheet shape is slightly wider than the width of the palms arranged on the left and right since the cleaning liquid is wasted if it is too wide. It is preferable to keep it.

A hand washing apparatus according to a third aspect of the present invention comprises:
A high-pressure air supply unit, a gas-liquid mixing unit that mixes the high-pressure air supplied from the high-pressure air supply unit with a hand washing liquid, and a mixture discharge port that discharges the mixture mixed by the gas-liquid mixing unit. And is provided. In addition, a turbo fan, an air compressor, or the like can be given as the high-pressure air supply unit.

According to the third aspect, the high-pressure air supplied from the high-pressure air supply unit and the cleaning liquid are mixed by the gas-liquid mixing unit, and the mixture is discharged from the mixture discharge port.
Therefore, even when the supply pressure of the cleaning liquid is low, the cleaning liquid is mixed with the high-pressure air and the discharge pressure is added by the high-pressure air, so that the discharge pressure of the cleaning liquid increases. For this reason, according to the third aspect, even when the supply pressure of the cleaning liquid is low, it is possible to clean the hands in a short time. Further, when the cleaning liquid is mixed with high-pressure air and discharged from the mixture discharge port as in the third aspect, the cleaning liquid can be saved compared with the case where only the cleaning liquid is discharged from the discharge port, and the economy can be reduced. It is a target.

A hand washing apparatus according to a fourth aspect of the present invention comprises:
The hand washing device according to the third aspect further includes a nozzle having the mixture discharge port, and the nozzle is provided on a surface of the user's hand that is extended so as to intersect the mixture with a direction in which the hand extends. The sheet is ejected along the sheet.

According to the fourth aspect, the same advantages as in the first aspect can be obtained. However, the third
In the embodiment, similarly to the conventional hand washing apparatus, a faucet-shaped fitting or a shower head may be used instead of the nozzle.

A hand washing apparatus according to a fifth aspect of the present invention comprises:
In the hand washing device according to the fourth aspect, the width of the mixture injected in the sheet shape at the hand extending position is a width covering both palms arranged side by side. According to the fifth aspect, advantages similar to those of the second aspect can be obtained.

A hand washing apparatus according to a sixth aspect of the present invention comprises:
In the hand washing device according to any one of the third to fifth aspects, the drying air blow-out port for blowing air for drying the hands, and the gas-liquid mixing of the high-pressure air from the high-pressure air supply unit. And a switching unit for selectively switching and supplying one of the unit and the drying air outlet.

According to the sixth aspect, the high pressure air is discharged from the drying air discharge port by switching the high pressure air to the drying air discharge port by the switching section. Can be dried. According to the sixth aspect, since the high-pressure air from the same high-pressure air supply unit is used for both the discharge of the cleaning liquid and the drying, it is not necessary to provide a dedicated high-pressure air supply unit for each, and the apparatus can be downsized. In addition, cost can be reduced.

A hand washing apparatus according to a seventh aspect of the present invention comprises:
In the hand washing apparatus according to the sixth aspect, in a standby state in which the mixture and the drying air are not discharged, the high-pressure air supply unit stops operating and the switching unit causes the high-pressure air supply unit to perform the gas-liquid mixing. A control unit that controls the high-pressure air supply unit and the switching unit so as to be connected to the unit.

As in the seventh aspect, if the switching unit controls the high-pressure air supply unit to be in a state of being connected to the gas-liquid mixing unit at the time of standby, the switching unit switches the rotation type switching valve or the like. Even when a device requiring a relatively long time for the operation is used, the time lag at the start of the discharge of the cleaning liquid can be reduced, which is preferable. This is because the operation of hand washing usually shifts to washing and drying.

A hand washing apparatus according to an eighth aspect of the present invention comprises:
In the hand washing device according to any one of the third to fifth aspects, the mixture discharge port is also used as a drying air discharge port for blowing air for drying the hands, The cleaning liquid is supplied to the gas-liquid mixing section at the time of discharge, and the supply of the cleaning liquid to the gas-liquid mixing section is stopped at the time of the drying air blowing.

According to the eighth aspect, since the mixture discharge port is also used as a drying air discharge port, it is possible to save space and reduce costs near the hand washing place. Further, when the mixture discharge port is also used as a drying air discharge port as in the eighth aspect, it is possible to switch between the hand-washing state and the drying state only by whether or not the cleaning liquid is supplied to the gas-liquid mixing section. This eliminates the need for the switching section as in the sixth and seventh aspects, and can further reduce costs from this point.

A hand washing apparatus according to a ninth aspect of the present invention comprises:
In the hand-washing device according to any one of the third to eighth aspects, a path through which air to be blown out from the drying air outlet or a part of the mixture is discharged from the mixture discharge port. A heating unit for heating the high-pressure air is provided in a path through which both the air to be blown and the air to be blown out from the drying air outlet are passed.

It is preferable to provide a heating section as in the ninth aspect, since heated air is discharged from the air outlet for drying, which facilitates hand drying. If a heating unit is provided in a path through which both air to be discharged from the mixture discharge port and air to be discharged from the drying air discharge port pass, the cleaning liquid is mixed with the heated air. Since the mixture is discharged from the discharge port, for example, when the cleaning liquid is hot water, its temperature is prevented from lowering, and when the cleaning liquid is water, its temperature rises.

May be introduced into the nozzle. In this case, only one inlet is required for the nozzle. When the gas-liquid mixing section is provided outside, a faucet-shaped fitting, a shower head, or the like can be used instead of the nozzle.

As shown in FIG. 2, the drying air discharge fitting 6 is also provided on the sink 9. The water discharge sensor 7 is a sensor that senses that the hand 1 is put out as shown in FIGS. 2 and 3, and the drying sensor 8 is located near the drying air discharge port 6 a of the drying air discharge fitting 6. It is a sensor that senses that the hand 1 is out.

As shown in FIG. 1, the water inlet 2 of the nozzle 4
The water supply pipe 26 connected to 3 is provided with a water supply electromagnetic valve 12. The other end of the air transport pipe 25 whose one end is connected to the air inlet 20 of the nozzle 4 is connected to one port of the switching solenoid valve 13. The other port of the solenoid valve 13 is connected to an outlet port of the turbo fan 11 via a connection pipe 27. The branch pipe 28 branched at the branch point A of the connection pipe 27 is connected to one port of the switching solenoid valve 14. The other port of the solenoid valve 14 is connected to the connection pipe 2

However, for example, a rotary switching valve or the like may be used as the switching unit instead of the switching solenoid valves 13 and 14.

As described above, since the heating unit 10 is provided between the solenoid valve 14 and the drying air discharge fitting 6, air to be discharged from the drying air discharge port 6a passes through. It will be provided in the route. The heating unit 10 may be provided between the turbo fan 11 and the branch point A. In this case, the heating unit 10 is provided in a path through which both air to be discharged from the injection port 24 of the nozzle 4 as a part of the mixture 3 and air to be discharged from the drying air discharge port 6a pass. Will be.

The control unit 15 is constituted by using, for example, a microcomputer or the like, and controls the solenoid valves 12 to 14, the heating unit 10 and the turbo fan 11 in response to sensing signals from the water discharge sensor 7 and the drying sensor 8. I do.

For example, the control unit 15 closes the solenoid valve 12 and turns off the turbo fan 11 and the heating unit 10 in a standby state where no sensing signal is obtained from the sensors 7 and 8.
Let it. In this standby state, the solenoid valves 13 and 14 may be turned on or off, but the control unit 15 turns on the solenoid valve 13 and turns off the solenoid valve 14, and sets the turbo fan 11 to the nozzle 4. It is preferable to control so as to be connected to the gas-liquid mixing chamber 22. This is because even when the time lag of the solenoid valve 13 is large, the time lag of the start of the discharge of the mixture 3 can be reduced when the mixture 3 is discharged from the nozzle 4 next time. In particular, when a rotary type switching valve requiring a relatively long time for the switching operation is used instead of the solenoid valves 13 and 14, the turbo fan 11 is connected to the gas-liquid mixing chamber 22 of the nozzle 4 in the standby state. It is preferable to be in a state.

To As a result, neither water nor high-pressure air is supplied to the nozzle 4 and the injection of the mixture 3 from the nozzle 4 stops, and instead, after the high-pressure air from the turbo fan 11 is heated through the heating unit 10, The hand 1 is supplied to the drying air discharge fitting 6 and is blown out from the discharge opening 6a, so that the hand 1 is dried.

According to the present embodiment, as shown in FIGS. 2 and 3, a mixture 3 of water and air is formed into a sheet along a plane intersecting the direction X in which the user's hand 1 is inserted. Therefore, the user can clean the hands in a short time only by performing a simple operation of pulling out and inserting the hands back and forth without performing hand-rubbing and the like in which the hands are rubbed.

Then, the water is singly injected into the injection port 2 of the nozzle 4.
4 is mixed with the high-pressure air supplied from the turbo fan 11 and the mixture 3 is not discharged from the injection port 2.
4 is discharged. Therefore, even when the water supply pressure is low, the water is mixed with the high-pressure air and the discharge pressure is added by the high-pressure air, so that the discharge pressure of the water increases. For this reason, even if the water supply pressure is low, it is possible to clean the hands in a short time. Also, water can be saved and it is economical.

Further, according to the present embodiment, as described above, the high-pressure air is switched and supplied to the drying air outlet 6a by the solenoid valves 13 and 14, so that the high-pressure air is supplied to the drying air outlet 6a. The hand 1 can be dried after hand washing. In the present embodiment, since the high-pressure air from the same turbo fan 11 is also used for water discharge and drying, it is not necessary to provide a dedicated high-pressure air supply unit such as a turbo fan, thereby reducing the size and size of the apparatus. Cost can be reduced.

The heating unit 10 is connected to the turbo fan 1
When provided between 1 and the branch point A, the air to be the mixture 3 can also be heated by the heating unit 10. Therefore, in this case, since the water is mixed with the heated air and is injected from the injection port 24 of the nozzle 4,
As the temperature of water rises and hot air hits hand 1,
It can relieve the discomfort of feeling cold when washing hands.
