In the present invention, the foot switch 10 touched by the foot is provided with a permanent magnet 12 is installed on the foot plate 11, as shown in Figure 5, corresponding to the synthetic resin molded switch (reed) switch (13) Is installed on the body and configured.

That is, the switch contact of the foot switch 10 is composed of a permanent magnet 12 and a synthetic resin molded type reed switch 13.

Here, when the reed switch 13 receives an external magnetic field by the permanent magnet 12, both ends of the lead piece are magnetized, and accordingly, anti-magnetic force is generated in the opposing contact portion. If the magnetic attraction force beats the elastic force of the lead piece, the contact point When the permanent magnet 12 is closed and the permanent magnet 12 is away from the reed switch 13, since the reed force of the lead piece is higher than the magnetic attraction force, the contact is opened.

In addition, the foot switch 10 is installed vertically to the bottom edge of the sink, as shown in Figure 2, as shown in Figure 1 the lower end of the foot plate 11 protrudes forward to form a locking protrusion (11a) have.

In other words, the front foot is caught from the locking portion 11a by the touch operation that the user presses the sole to the front foot, and the foot 11 is naturally pressed.

And the footrest 11 is formed of a groove in the form of a checkerboard to prevent slipping when pressed to the sole.

The controller 20 receiving the touch signal of the scaffold switch 10 is configured to output the water jetting and exponential signals according to the input signal.

On the other hand, when the user opens the solenoid valve 30 by outputting the water discharge signal for water supply to the touch signal in a state where the user sets the hot water of a suitable temperature mixed with cold and hot water to the faucet, the built-in According to the established program, the cold water solenoid valve is opened first, and the hot water solenoid valve is controlled in order to open later.

The reason is that since hot water is higher than cold water, when the solenoid valves for cold and hot water are opened at the same time, hot water that is not mixed with cold water is discharged to the faucet 60 to prevent hand burns.

In the case of the exponent, the hot water solenoid valve is closed first, and the cold water solenoid valve is closed later, as opposed to water supply.

In addition, the controller 20 is configured to automatically output the exponent signal after approximately three minutes if the touch signal for the exponent is not input after the output of the jetting signal by the built-in program.

And the solenoid valve 30 is controlled by the output signal of the controller 20 to be opened and closed, the valve 30 is connected to the faucet hose 50 and the cold and hot water discharge (70). On the other hand, the solenoid valve 30 is a manual adjustment knob to manually open and close the solenoid valve 30 in case of power supply interruption due to a power failure or an electrical failure or an emergency such as an abnormality (fault) in the control circuit. (31) is provided.

That is, in the case of emergency as described above, the solenoid valve 30 is operated as a general faucet by operating the solenoid valve 30 with the manual adjustment knob 31 as shown in FIG. 3b, and after repairing, the solenoid valve 30 is closed as shown in FIG. 3a. Can be used as a step opening and closing type.

Manual opening and closing of the solenoid valve by the manual adjustment knob 31 is connected to the spring 34 and the diaphragm 32 having the plunger 33 and the supporting member 32a supported by the spring to be connected to the inlet 34 of the washing water. The hose 50 for the faucet connected to the cold / hot water discharged water 70 and the outlet 35 is interrupted.

The manual adjustment knob 31 is a bolt type applied to the three-threaded screw, the manual adjustment knob 31 in the state of opening and closing by solenoid in stepping opening and closing method of the present invention as shown in Figure 3a is released. If only one rotation of the manual control knob 31 is tightened as shown in Figure 3b advances and the end is in communication with the washing water inlet 34 and the outlet 35, which is blocked by pressing the support member (32a) of the diaphragm (32). Let's do it.

In addition, the hot water flowing through the hot water index field 70 is discharged to the faucet through the solenoid valve for hot water at a temperature of 80 ° C. The diaphragm made of ethylene propylene (EPDM) rubber material by hot water ( In order to prevent thermal deformation of 32, the diaphragm 32 manufactured by adding fluorine for enhancing heat resistance to the ethylene propylene rubber is used as the solenoid valve 30 of the present invention.

As described above, the solenoid valve 30 is opened and closed not only by the electromagnetic force by the solenoid but also by the rotation operation of the manual adjustment knob 31 to connect and block the inlet 34 and the outlet 35.

In addition, the power supply unit 40 applies driving power to the controller 20 and the solenoid valve 30. The power supply unit 40 may be configured as an electric type as shown in FIG. 1 or a battery type type as shown in FIG.

In the case of the electric type, the outlet 41 and the electric adapter 42 of FIG. 1 are provided, and in the case of the battery type, the controller and the battery 90 are installed together in the control box 80 as shown in FIGS. 2 and 4.

In the figure, reference numeral 81 denotes a control box cover.

In the case of supplying power to the battery 90, the battery 90 needs to be replaced because the battery 90 is discharged after a certain time of use.

When the replacement time of the battery 90 is reached, when the foot switch 10 is touched for cleaning, the controller 20 makes the water jet for 2 seconds and the water jet for 3 seconds as one operation. You will be alerted. If this operation is repeated about 100 times, it will be completely discharged.

1 and 2, the foot switch, the solenoid valve for cold water and hot water is fastened by the connection between the connector to the electric controller 20 and the battery control box 80, the assembly is incorrectly fastened In order to prevent defects, the male and female connectors are configured not to be fastened unless they match with each other.

When described in detail the operation by the configuration of the stepping switch type water supply device of the present invention as described above.

The installation state of the present invention is stored in the sink case lower case as shown in Figure 2, the foot switch 10 for operation is installed in the lower center of the sink stand.

First, the user should set the water discharge amount and the temperature of the washing water with the faucet 60 in advance before using the stepping-opening water supply device of the present invention.

Then, when the user needs to open the faucet 60 in order to wash or wash the food ingredients, the front sole is raised by pressing the foot 11 of the foot switch 10 to the front sole by raising the sole. The footrest 11 is pressed while being caught. By the touch operation, the permanent magnet 12 is in contact with the reed switch 13, the lead piece contact of the reed switch 13 is turned on.

Accordingly, the touch signal is transmitted to the controller 20 to output the water discharge signal for opening the solenoid valve 30 in the controller 20.

The solenoid valve 30 is opened by opening the solenoid valve 30 as the electromagnetic force of the solenoid retracts the plunger 33 by the water discharge signal so that the inlet 34 and the outlet 35 of the washing water blocked by the diaphragm 32 communicate with each other. Water is discharged in the number through the faucet hose 50 is connected to the outlet 35 through the water discharge 70 connected to).

When the faucet 60 is to be closed, when the footrest 11 is touched again as described above, the touch signal is input to the controller 20. Accordingly, the exponent signal is output from the controller 20 so that the electromagnetic force of the solenoid disappears. As the plunger 33, which has been pulled forward, the diaphragm 32 blocks the inlet 34 and the outlet 35 of the washing water, the solenoid valve 30 is closed, and the washing water for the faucet 70 is used for the faucet. It will not flow to the hose 50.

After the controller 20 outputs the water discharge signal to the solenoid valve 30 together with the above-described exponential method based on the scaffolding touch, the controller 20 may save water after approximately 3 minutes if the touch signal is not input to the controller 20 again. 20 outputs an index signal to the solenoid valve 30 to close the solenoid valve 30 to automatically flush the washing water.

The automatic indexing operation is performed by the timer function of the controller 20, and the automatic index processing is performed after a set time after jetting.

In this way, the faucet 60 can be opened and closed simply by the one-touch method of the foot switch 10.

As the above, the solenoid valve is operated by the discharge water and the exponent signal output from the controller. When suitable mixed water mixed with cold and hot water is used, the solenoid valve for cold water is first opened when water is discharged by the program built in the controller. The hot water solenoid valve is later opened to discharge the mixed water, and when the hot water solenoid valve is closed first, the cold water solenoid valve is later opened to discharge the mixed water.

On the other hand, in case of an emergency such as a power failure, an electrical failure, or an abnormality in the control circuit, the manual control knob 31 installed in the solenoid valve 30 is rotated to one side to open the solenoid valve 30 as shown in FIG. 3B. It can be used like a normal faucet.

As shown in FIG. 3, when the manual adjustment knob 31 of FIG. 3A is rotated to one side, the plunger 33 pushes the support member 32a of the diaphragm 32 as shown in FIG. 3B. Is reversed and compressed by pressing the spring. Accordingly, the inlet 34 and the outlet 35 of the washing water blocked by the diaphragm 32 communicate with each other to open the solenoid valve 30.

In addition, when the manual adjustment knob 31 is rotated to the other side, as the solenoid valve 30 is closed due to the reverse operation of the above, it can be used in stepping and closing type.

And when the power supply method is a battery type as shown in FIG. 2, not electric as shown in FIG. 1, when the wash water repeats the jetting water and the water in a short time for about 2 to 3 seconds, the discharge of the battery 90 is almost completed. So you can replace it at the right time.

According to the technical configuration of the present invention as described above, it is possible to wash water and water while washing dishes in the kitchen without using hands, which is convenient and easy to wash, and even if the hands are dirty or have detergent, It is possible to discharge water and index by foot without touching, and the surrounding area of the faucet is always clean and hygienic, and it can be easily operated by foot in the water and index operation of washing water, so that unnecessary water can be eliminated. Water saving effect can be obtained.
