Abstract

PROBLEM TO BE SOLVED: To discharge a small amount of water to a comfort discharge position by constituting a water discharge device of a discharge position adjusting means for changing a flow rate adjusting means and a discharge opening for making the discharge opening and the discharge amount of water constant. SOLUTION: A water faucet 1, a flow rate control valve 2, an on/off valve 3, an air mixing part 4 and a discharge port 9 are arranged in order, and a forcible air supply device 5 is connected through an air supply pipe passage 11 to the air mixing part 4. When a part of a human body is put on a discharge port 9, a control part 6 calculates a distance up to a detecting matter by the output of a human body sensor 8, determines the output of the forcible air supply device 5, and discharges water mixing bubbles from the discharge port 9. The flow rate of discharged water is constant regardless of pressure because it passes through a flow rate adjusting means, and, since the bubbles are mixed, sufficient water washing feeling can be realized by a small amount of water. When the part of the human body is put near the discharge port 9, the control part 6 makes a bubble mixing amount a small amount by the output of the sensor 8, and, since the bubble mixing amount is set large in the case where it is put at a position separated from the discharge port 9, water can be discharged at an always convenient position.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the present invention. A water stopcock 1, a flow control valve 2 for adjusting the flow rate, an open / close valve 3 for turning on / off the discharge, an air mixing section 4 for mixing air, and a discharge port 9 at the tip of the water discharge device main body 7 from the water supply pipe 12. The forced air supply device 5 is connected to the aeration unit 4 through the air supply pipe 11. The on-off valve 3, the forced air supply device 5, and the detection sensor 8 for detecting a part of the human body are connected to the control unit 6.

In the above configuration, if the user holds a part of the human body over the discharge port 9, the control unit 6 calculates the distance to the detected object based on the output of the human body detection sensor 8, and outputs the output of the forced air supply device 5. To determine. Thereafter, by opening the forced air supply device 5 and the opening / closing valve 3, water containing air bubbles can be discharged from the discharge port 9. The discharged water passes through the flow control means, so the flow rate of the water is constant regardless of the pressure.Since air bubbles are mixed in, the amount of water can realize a sufficient hand washing feeling even with a small flow rate, and high water saving is expected. can do.

When a part of the human body is held over the discharge port 9, the control unit 6 sets the amount of air bubbles to be small by the output of the sensor 8. Therefore, the water mixed with the air bubbles is discharged to a part of the human body held over the discharge port 9. Conversely, when a part of the human body is held over a position distant from the discharge port 9, the output of the sensor 8 causes the control unit 6 to set a large amount of air bubbles. Therefore, the hot and cold water mixed with air bubbles is discharged to a part of the human body held over a position distant from the water outlet 9, and the water is always discharged to a comfortable and convenient position within the sensing area of the sensor 8. Can be provided.

FIG. 4 shows an embodiment in which the human body detection sensor 8 and the touch switch 10 are used in combination. The amount of air entrapment is set to be small when discharging water by a signal from the detection sensor 8, and the amount of air entrapment is set to be large when discharging water by a signal from the touch switch 10. Therefore, when a general human uses the water, the water is discharged by a signal from the human body detection sensor 8 in order to insert a part of the human body to the vicinity of the discharge port 9. Therefore, the amount of air mixing is small, and water can be discharged to the protruded position. Further, when a person or a child using a wheelchair uses the touch switch 10, the touch switch 10 is necessarily pressed because a part of the human body cannot be extended to the discharge port 9. Therefore, water is discharged by a signal from the touch switch 10. Therefore, the amount of air mixing is large,
Discharge can be performed to a position distant from the discharge port 9, and a comfortable discharge position can always be provided according to the user.

FIG. 5 shows an embodiment of a handle type water discharging device. The appearance is the same as a normal single faucet, but the amount of air mixed in can be changed by rotating the air amount handle 13, so that the same effect as changing the flow rate despite the water amount being constant is obtained. Can be obtained.

FIG. 6 shows an embodiment of a single faucet type water discharging device. By rotating the air amount handle 13, the amount of air mixed in can be changed. Further, the water spouting device may be a face washing device, an eye washing device, a water drinking device, or the like in which the direction of the water spouting section 14 is upward.

In the embodiment, the forced air bubble mixing means has been described as the water discharging position adjusting means. However, it is needless to say that the water discharging position adjusting means may be a flow path diameter adjusting means or a water discharging angle adjusting means.
