Abstract

PURPOSE:To improve ease of handling for a person having trouble in the hand by operating a control valve with a control circuit manipulating a sensor switch provided on a floor of a bathroom or a shower room. CONSTITUTION:When a shower is turned ON by stepping on a sensor switch 8, touching it lightly or crossing it, a signal is sent to a control circuit 10. When the signal is inputted, the control circuit 10 works to open control valves 6 and 7. As the control valves 6 and 7 are set lower in temperature and the level of water beforehand with a resetting circuit, the temperature of hot water delivered initially is too low to cause a scald and the amount of water is limited. Then, when the sensor switch 8 is operated with a foot to raise the temperature or increase the amount of water, signals involved are inputted into the control circuit 10. With the inputting of the signals, the control circuit 10 sends signals to the control valves 6 and 7 to control the temperature and the amount of water to those desired inputted into the sensor switch 8 by a foot. When the use of the shower ends, a stop signal is inputted into the sensor switch 8 by a foot to close the control valves 6 and 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower device which can stop the hot water supply and adjust the hot water temperature and the hot water amount without using hands.

[0002]

2. Description of the Prior Art In a conventional shower device, as shown in FIG.
It is configured by operating the handle 2 or the lever 01. In the figure, 03 is a shower head, 04 is a hot water supply line,
Reference numeral 05 is a water supply line.

[0003]

Therefore, there are the following drawbacks.

A. It is difficult to use for people with limited mobility.

B. When both hands are closed, the lever 01 cannot be operated.

C. If your hands are covered with soap etc., your hands will slip easily when you turn the lever 01.

D. Depending on the position of the lever 01, it is necessary to bend over one by one.

E. It is difficult to adjust the hot water temperature and amount, and there is wasteful hot water until the temperature and amount are adjusted appropriately.

An object of the present invention is to provide a shower device that solves the above disadvantages a to e.

[0010]

The structure of the shower apparatus according to the present invention is as follows.

A sensor switch is installed on the floor of the bathroom or shower room, control valves are attached to the water supply line and the hot water supply line, and a control circuit is provided. A. A signal sent from the sensor switch opens the control valve to start hot water supply; b. Controlling the control valve by the signal from the sensor switch to adjust the hot water temperature and hot water amount, c. Stop the hot water supply by controlling the control valve by the signal from the sensor switch, d. A shower device, characterized in that after the hot water supply is stopped, the control valve is controlled to reset the hot water temperature and the hot water amount at the start of reuse to below a certain level by a reset circuit.

[0012]

Infrared rays, light, etc. can be used as the sensor switch, and this sensor switch is installed on the floor. When the person using the shower operates the shower ON by stepping on, touching, or crossing the sensor switch with his / her foot, a signal is sent to the control circuit. The control circuit opens the control valve when this signal is input. Since the control valve is set in advance by the reset circuit so that the amount of water is low and the amount of water is low, the temperature of the hot water that comes out first is low and there is no fear of burns and the amount of water is small. Next, when the sensor switch is operated to raise the temperature or increase the amount of water with the foot, these signals are input to the control circuit. Upon receiving this input, the control circuit sends a signal to the control valve to control the desired temperature and amount of water input to the sensor switch with the foot. Then, when the use of the shower is finished, when the stop signal is input to the sensor switch, the control circuit closes the control valve. At the same time, the reset circuit in the control circuit resets the opening degree of the control valve so that the hot water temperature and the water amount at the time of reuse become the minimum set values.

The input method for the sensor switch may be a method of applying a pulse across the sensor, a combination of operations of a plurality of sensor switches, or the like.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 1 is a shower head, 2 is a mixer, 3 is a manual operation lever, 4 is a hot water supply line, 5 is a water supply line, 6 is a hot water supply control valve attached to the hot water supply line 4, and 7 is water supply. Water supply control valve attached to line 5, 8
Is a sensor switch, 9 is a signal line, and 10 is a control circuit to perform the following control.

A. The control valve is opened by the signal sent from the sensor switch to start hot water supply.

B. The control valve is controlled by the signal from the sensor switch to adjust the hot water temperature and hot water amount.

C. The control valve is controlled by the signal from the sensor switch to stop hot water supply.

D. After the hot water supply is stopped, the reset circuit controls the control valve to reset the hot water temperature and the hot water amount at the start of reuse to a certain level or less.

Next, the operation of the embodiment will be described.

A signal is sent to the control circuit 10 when the shower ON operation is performed by a method such as stepping on the sensor switch 8, touching it lightly, or crossing it. Control circuit 1
0 opens the control valves 6 and 7 when this signal is input. Since the control valves 6 and 7 are set in advance by a reset circuit so as to have a low temperature and a small amount of water, the temperature of the hot water discharged first is low, there is no fear of burns, and the amount of water is small.

Next, when an operation of raising the temperature or increasing the amount of water is performed with the foot on the sensor switch 8, these signals are input to the control circuit 10. When the control circuit 10 receives this input, it sends a signal to the control valves 6 and 7 to control the desired temperature and amount of water input to the sensor switch 8 with the foot. Then, when use of the shower is finished, when a stop signal is input to the sensor switch 8 with the foot, the control circuit 10 closes the control valves 6 and 7. At the same time, the reset circuit in the control circuit 10 resets the opening degrees of the control valves 6 and 7 so that the hot water temperature and the water amount at the time of reuse become the minimum of the set values.

In the case of the embodiment, the sensor switch 8
The input method for is done with pulses across the sensor 8. The lever 3 is for manual operation just in case.

[0023]

As described above, the present invention has the following effects because the shower can be operated entirely by the feet.

A. Convenient for the handicapped.

B. Even if both hands are closed, you can operate the shower, which is convenient.

C. You can operate the shower without problems even if your hands are covered with soap.

D. It is convenient because you do not have to bend over when operating the shower.

E. When the shower is stopped, the hot water temperature and hot water amount are automatically reset to the minimum set value by the reset circuit, so hot water does not suddenly come out when reusing and the time to adjust the temperature is short. There is no waste of hot water and it is energy saving.
