Description

[0001] APPARATUS FOR OPENING AND CLOSING [0002]

The present invention relates to an automatic opening / closing apparatus for a water supply valve, and more particularly, to a water supply valve automatic opening and closing apparatus for automatically opening and closing a water supply valve by sensing a foot of a user with an ultrasonic sensor.

Generally, a water supply facility is installed in a kitchen, a bathroom, a toilet, etc. of each household, and this water supply facility supplies or cuts water to use by operation of the valve, but the valve has a drawback There is a problem that unnecessary water is wasted.

On the other hand, as a prior art for solving such a problem, Korean Registered Patent Publication No. 10-1021439 (name: a valve opening / closing apparatus) (hereinafter referred to as "prior art") is exemplified.

The prior art includes a touch portion for pulling or releasing a wire portion in response to pressing of an object, a valve opening / closing device for opening and closing the water supply valve as the wire portion is pulled by the touch portion, And a wire portion connecting the touch portion and the valve opening / closing device, and transmitting the pull of the touch portion to the valve opening / closing device.

However, in the above prior art, in order to open the valve opening / closing device, the opening state of the valve opening / closing device can be maintained only when the pulling force continuously acts on the wire portion by continuously pressing the touch portion as a mechanical driving method. If the pressing of the touch portion is canceled The pulling of the wire portion is immediately terminated and the valve opening / closing device is closed again, which makes it inconvenient to use. Most of all, the mechanical method uses a large number of parts for the operation, have.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a water valve automatic opening / closing apparatus for automatically opening and closing a water supply valve by sensing a user's foot with an ultrasonic sensor.

According to another aspect of the present invention, there is provided a water supply valve automatic opening / closing apparatus for automatically opening and closing a water supply valve installed in a sink, the water supply valve having an installation groove formed at a lower end of the sink and into which a user's foot is inserted, An ultrasonic sensor installed in an installation groove provided at the lower end of the sink for sensing a foot of a user using ultrasonic waves, an electronic control valve installed in an internal flow path of the water supply valve by receiving a signal sensed by the ultrasonic sensor, And a control unit for supplying power and controlling the electronic control valve to open and close so as to open and close the flow path of the water supply valve.

The present invention detects the user's foot with an ultrasonic sensor and automatically opens and closes the water supply valve by electronic means, so that it is possible to realize the convenience of operation compared with the conventional mechanical type opening and closing apparatus, It is possible to prevent problems such as breakdown.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a diagram showing the entire configuration of a water valve automatic opening / closing apparatus according to a preferred embodiment of the present invention; Fig.
Fig. 2 is a diagram showing a circuit configuration of the water valve automatic opening / closing apparatus shown in Fig. 1; Fig.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following detailed description, exemplary embodiments of the present invention will be described in order to accomplish the above-mentioned technical problems. And other embodiments which may be presented by the present invention are replaced by descriptions in the constitution of the present invention.

On the other hand, the water valve automatic opening and closing apparatus proposed in the present invention is used in various water supply facilities such as a kitchen, a bathroom, and a toilet. In the following description, the water valve automatic opening / closing apparatus will be described as being typically installed in a kitchen sink.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a diagram showing the entire construction of a water valve automatic opening / closing apparatus according to a preferred embodiment of the present invention, and Fig. 2 is a diagram showing a circuit configuration of an automatic water valve opening / closing apparatus shown in Fig.

As shown in FIGS. 1 and 2, the sink 10 is provided with a water valve 20, which is connected to the water pipe to discharge tap water supplied from the water pipe . An electronic control valve 40 is installed in the water valve 20. The electronic control valve 40 selectively operates according to a signal applied to the control unit 36, And the tap water is supplied and blocked.

The automatic water supply valve opening / closing apparatus of the present invention, which is an apparatus for automatically opening and closing the water supply valve 20, is installed in an installation groove 12 installed at the lower end of the sink 10, And an electronic control valve 40 installed in an internal flow path of the water supply valve 20 to receive a signal sensed by the ultrasonic sensor 30 to control operation of the water supply valve And a control unit (36) for opening and closing the flow path of the fuel cell (20). A power supply unit is connected to the control unit to supply power to the electronic control valve 40 according to a signal from the control unit so that the electronic control valve 40 can be opened and closed.

The present invention is characterized in that the ultrasonic sensor 30 is used as a configuration of the sensing unit, which is means for outputting a signal to the control unit 36 to sense the foot of the user and drive the electronic control valve 40.

The ultrasonic sensor 30 senses the user's foot and outputs a signal to the controller 36. [ The ultrasonic sensor 30 is installed in an installation groove 12 formed at the lower end of the sink 10.

The ultrasonic sensor 30 includes a transmitting-side ultrasonic sensor for emitting ultrasonic waves and a receiving-side ultrasonic sensor for receiving ultrasonic waves emitted from the transmitting-side ultrasonic sensor. When the user's foot is inserted into the mounting groove, The ultrasound sensor 30 is received by the ultrasound transducer in a state in which the ultrasound wave emitted from the sensor is incident on the user's foot and receives a signal from the controller 36 by sensing the foot of the user, And the electronic control valve 40 is operated to automatically open the flow path of the water supply valve 20. That is, in the present invention, tap water can be used by automatically opening the water supply valve 20 through the ultrasonic sensor 30 for sensing the foot of the user.

At this time, the control unit 36 allows the user to use the tap water continuously by opening the electronic control valve 40 even if the user's feet get out of the installation groove 12 through the setting, And when the ultrasonic sensor 30 senses the user's foot again, the opening of the electronic control valve 40 is closed to cut off the supply of tap water, so that the convenience of use can be set.
