Abstract

PURPOSE:To faciliate repair and maintenance for electric failure by disposing a control box for controlling the opening and closing of an electric water stop valve in the rear of a switch box in such a manner as to be removably connected thereto. CONSTITUTION:A switch box 5 opened forward is installed below a washstand or a kitchen unit 4 constructed so that a water tap faucet 2 is provided on the top plate 1 and an electric water stop valve 3 is installed in the interior thereof. A control box 6 for controlling the opening and closing of the electric water stop valve 3 is disposed in the rear of the switch box 5 in such a manner as to be removably connected to the switch box 5. The foot is detected in the switch box 5 by a foot sensor 7 fitted to the control box 6, and the detection signal is sent through the control box 6 to the electric water top valve 3 to open and close the valve 3. Thus, the control box 6 is taken out with the switch box 5, and the control box 6 is detached to be subjected to repair and maintenance for electric failure.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology that allows a water faucet to be turned on and off using a foot sensor placed at the bottom of a sink or kitchen unit.

0002

2. Description of the Related Art Conventionally, as shown in FIG.
A water faucet 2 is disposed inside the faucet 2, an electric water stop valve 3 for opening and closing the flow path in the faucet 2 is disposed inside, and a kitchen unit 4
A control box 6 for opening and closing the electric water stop valve 3 and a foot sensor 7 for detecting the tip of the foot and opening the electric water stop valve 3 to discharge water from the faucet 2 are provided at the bottom of the water tap.

0003

[Problem to be Solved by the Invention] Conventionally, when a malfunction occurs in which no water is discharged even when detected by the foot sensor 7, the water is stored deep inside the kitchen unit 4. The control box 6 must be removed, which requires time and effort for maintenance.Furthermore, the foot sensor 7 and the control box 6 are installed in different locations, making the wiring complicated and making installation or removal difficult. It was time consuming to do the work.

The present invention has been made in view of the above circumstances, and its purpose is to enable easy removal of the control box for troubleshooting and maintenance, and to eliminate differences in the height of the depression. The purpose of the present invention is to provide a foot-type automatic water supply device for washbasins that can be applied to the bathroom.

[0005]

[Means for Solving the Problems] The foot-type automatic water supply device of the present invention has a water supply tap 2 on a top plate 1, and a water stop valve 3 installed inside a washstand or a kitchen unit 4. An open switch box 5 is installed, and a control box 6 for controlling the opening and closing of the electric water stop valve 3 is placed behind the switch box 5 and removably connected to the switch box 5. A foot sensor 7 is attached to the control box 6 to detect and transmit a signal to the electric water stop valve 3 via the control box 6, and this configuration solves the above problem.

[0006]

[Operation] The control box 6 can be taken out together with the switch box 5, and the control box 6 can be removed to repair electrical failures or perform maintenance.Also, by removing and separating the switch box 5 and the control box 6, the The switch box 5 can be adapted to the height of the dirt 8.

[0007]

[Embodiment] This embodiment concerns a kitchen unit, in which a water tap 2 is disposed on the top plate 1 of the kitchen unit 4, and a water tank 9 is attached to the center through an opening. Two electric water shutoff valves 3 are installed inside the kitchen unit 4, namely, an electric water shutoff valve 3a for water supply and an electric water shutoff valve 3b for hot water supply. Electric water stop valve 3
consists of a solenoid valve 10 with a built-in bypass valve and a strainer, and a stop valve 11 with a built-in check valve, and the water tap 2 is connected at the upper end.
The water is supplied from the lower end. This electric water stop valve 3 is connected to a control box 6 by an electric cord 12, and its opening/closing is controlled. The switch box 5 has an open front and is attached to the opening of the recess 8 of the kitchen unit 4. A control box 6 is disposed behind the switch box 5 and is removably connected to the switch box 5 by locking a locking hook 13 in a locking recess 14 in a detachable manner. control box 6
Sensor part 1 with foot sensor 7 arranged on the front side of
5 is provided protrudingly, and this sensor portion 15 protrudes into the switch box 5 from the rear opening and connects to the foot sensor 7.
is located inside the switch box 5. Since the control box 6 and switch box 5 are removably connected, when installing them in recesses 8 of different heights, the
It is only necessary to change the height of the switch box 5 as shown in FIG.

[0008] Then, when the user connects the power cord 16 and puts his or her foot F into the switch box 5 through the front opening,
As shown in FIG. 4, the foot sensor 7 detects the tip of the foot F, and a signal is transmitted to the electric water stop valve 3 via the control box 6, and the electric water stop valve 3 is opened and water at an appropriate temperature is supplied from the water tap 2. is discharged. When you want to stop discharging hot water,
When the foot F is placed in the switch box 5 again and detected by the foot sensor 7, this signal is transmitted to the electric water stop valve 3 and the electric water stop valve 3 is closed.

Next, if you place your foot F in the switch box 5 and water does not come out from the faucet 2, it may be due to a poor connection of the electric cord 12 or a failure in the foot sensor 7, so close the switch box 5. By taking it out, the control box 6 can also be taken out, allowing for easy inspection and repair. Incidentally, the entire rear part of the switch box 5 may be left open, and the control box 6 may be taken out from this opening.

[Effects of the Invention] In the present invention, a water tap is provided on the top plate, and a forward-opening switch box is installed at the bottom of a washbasin or kitchen unit with an electric water stop valve installed inside, and the switch box is installed at the bottom of the kitchen unit. A control box that controls the opening and closing of the electric water shut-off valve is placed in the rear and removably connected to the switch box, and the foot is detected inside the switch box and a signal is transmitted to the electric water shut-off valve via the control box. Since the foot sensor is installed in the control box, take out the control box along with the switch box.
The control box can be removed to perform maintenance or repair of electrical failures, and by removing and separating the switch box and control box, a switch box can be used depending on the height of the depression. It is.
