Abstract

PURPOSE: An automatic opening and closing apparatus of a valve for waterworks is provided to turn on and off automatically, and to control drain time and check valves and power by kicking a membrane switch with installing the membrane switch in the lower part of a sink and with mounting a controller around a faucet. CONSTITUTION: An automatic opening and closing device of a valve for waterworks is composed of a membrane switch(1) operated in case of pressure to be over 400g, and a controller(2) having an integrated circuit chip(2a) turning on and off power. Power is supplied from a power supply unit(4) of the controller through the membrane switch to the integrated circuit chip of the controller. The controller is connected to waterworks opening and closing solenoid valves(3,3'). The controller opens and closes solenoid valves, indicates discharge of a battery, adjusts time and checks troubles. The membrane switch is installed in the lower part of a sink, and the controller is mounted around the faucet. The valve is opened and closed with pushing or kicking the membrane switch in the lower part of the sink, and the automatic opening and closing device of the valve is used conveniently.

Description

Automatic openning and closing device of water-works valves}

The present invention relates to an automatic opening and closing device of a water valve using a membrane switch, in particular, the switch is mounted on the bottom of the lower sink of the faucet position to be opened and closed only by touching it with the foot, but only a little force is ON-OFF and the sludge It is not operated by force, and the controller installed near the faucet can perform various operations such as discharge of power supply, automatic opening / closing time control of faucet (valve), fault check of solenoid valve, power ON / OFF, etc. The automatic opening and closing device of the water supply valve with the function.

In general, the water tap (opening and closing valve) must be rotated left and right by hand when opening and closing. Therefore, when water is needed even when soap water or dirt is on your hands, you must operate the water tap with soap and dirt. There was an inconvenience.

Recently, the power is contacted once with the foot in front of the sink without opening and closing the faucet by hand, and once the power is cut off, the solenoid valve mounted on the faucet (valve) is operated to open and close according to the connection and disconnection of the power. Touch type switchgear of water supply valve was opened in Japan and spread in Korea.

However, as described above, the touch water valve opening and closing device is easy to open the water valve when the user touches with the foot when opening the faucet (valve), but the adult or children inadvertently touch or clean the water when the water is unnecessary. If you hit with a cleaner, etc., there was an unwanted tap water comes out.

By improving the shortcomings of the touch water valve opening and closing device, one optical sensor is installed at the top and the bottom of the water and sink, and when the human body approaches the two upper and lower optical sensors and the sensor detects the approach, And a tap water switching device was developed by an optical sensor that operates the solenoid valve to open and close the tap water, and was filed as an application number 2002-0014508 as of Mar. 18, 2002. However, since the device also needs to install two optical sensors, it requires a lot of manufacturing cost and consumer cost, and it has to be installed up and down.

The present invention to improve the shortcomings of the touch-type switchgear of the tap water valve and the switchgear by the optical sensor as described above to touch the membrane switch which is operated only at a certain pressure (400g) or more in order to open and close only when necessary Easy to install under the sink and adjust the outlet time, controller or solenoid valve fault check, power discharge, power on / off status, etc. It will be described in detail with reference to the accompanying drawings to provide an automatic opening and closing device of the water supply valve consisting of the upper portion of the faucet, that is installed near the faucet as follows.

1 is an overall arrangement of the interior of the device according to the invention.

Figure 2 is a state of use of the sink in which the device according to the invention is installed.

Opening / closing water supply opening and closing solenoid valves 3 and 3 'by operation of the membrane switch 1 and the membrane switch 1 as a substitute for a membrane keyboard operated only by pressing at a pressure of about 400 g or more. Function, battery discharge indication function, multi-step discharge time adjustment function with automatic discharge time adjustment, fault check function of controller (2) and solenoid valve (3) (3 '), and power on / off indication function It consists of a controller (2) with a built-in IC chip (2a), the power connection in the above + power source from the power supply (4) of the controller 2 through the membrane switch (1) (- Is connected to the integrated circuit chip (IC chip) 2a in the controller 2 to which the power is connected, and the controller 2 is connected to the water supply opening and closing solenoid valves 3 and 3 ', respectively, to + power and -power. Connected to the controller 2 When the AC power source used in homes is switched to DC power supply to supply power, the AC power supply is automatically turned on by the DC battery when the AC power is cut off or the AC power is not available at all. It is configured to be provided with a function to be supplied.

In the above, the controller (2) outside the discharge indicator to inform the discharge connected to the IC chip embedded therein, the indicator and switch for multi-step discharge time control to automatically adjust the discharge time, the controller (2) and the solenoid valve ( 3) It is composed of an indicator that (3 ') is broken and an ON-OFF indicator (all of which is not shown above) indicating whether a power supply is connected to the outside.

Automatic opening and closing device of the water supply valve of the present invention configured as described above is installed in the lower portion of the sink or sauna chamber equipped with the water supply opening and closing valve of the kitchen or sauna room, the controller (2) so that the naked eye can easily see When installed near the water tap, connect the power to the power supply (4), insert the battery, and keep it in the ON state, the indicator for discharging the battery will be turned off, and the numeric indicator for adjusting the drainage time will be The setting button (not shown) can be pressed and set, and the fault check lamps of the controller (2) and the solenoid valve (S / N Valve) (3) (3 ') remain off. When the battery is discharged and the discharge indicator lights up (in this case, it is automatically connected to the power source that converts the AC power to the home), replace the battery, and the controller and brush When the Lennoid Valve Fault Indicator is on, repair it. If you want to open the faucet (valve) in order to use the tap water, press the membrane switch (1) slightly with your foot (at a pressure of about 400g) and the controller (2). ) And the solenoid valve (3) (3 ') are discharged for the set time and close automatically when the time runs out. Also, the membrane switch (1) is applied to children's hands, adults' feet or cleaning tools. It is located in the bottom of the sink, which is in close contact, but the switch 1 is not turned on unless a certain pressure (400g or more) is applied, so it is safely maintained when not in use.

The automatic switching device of the water supply valve of the present invention is equipped with a discharge indicator, a discharge time indicator and a switch, a controller (2) and a solenoid valve (3) (3 ') failure indicator, and an ON-OFF indicator of a power supply. The controller (2) with built-in IC chip is located near the faucet (valve), so it can be easily detected with the naked eye by detecting whether the device is running, operating time, failure, etc. The membrane switch is mounted under the sink to control the device. It is easy to press the membrane switch (1) a little harder or hit it with your feet even when you are washing dishes or when water or soapy water is on your hands. Since the valve is opened, there is a safe and convenient effect.
