Abstract
Description
The present invention relates to a water-saving machine for a sink, wherein when the water is used in a sink, the sensing device detects the foot of the human body in close proximity to the water, thereby allowing water to be supplied only at a necessary moment, thereby preventing unnecessary water from being wasted when cooking or washing dishes .
Currently, water capacity and demand are increasing, but water supply is becoming less important and water conservation is getting more and more important.
As a result, there is a consensus on the seriousness of water-related problems such as lack of water resources and water pollution in the case of Korea, which is a water-scarce country. Various studies are under way.
Generally, a sink is used for kitchen work such as cooking and washing dishes. The basic structure includes a main body in which a plurality of storage chambers for storing kitchen utensils are formed and doors are installed in the respective storage chambers, A sink, and a top plate on which a cooking table is formed so that kitchen utensils can be placed or cooked.
In addition, a water supply facility such as a faucet is basically installed in the water supply tower to supply water necessary for cooking and washing dishes.
However, in the case of cooking and washing dishes in a sink, it is seldom necessary to continue watering continuously.
During the whole process of cooking and washing dishes, most of them do the trimming and cleaning of the vegetables or the washing of the dishes by using a scrubber. At this moment, watering is not needed.
In other words, when cooking or washing dishes, watering and singing are repeatedly required.
However, after opening the faucet for the first time, it is troublesome to repeatedly open and close the faucet while performing other operations such as cooking or washing dishes, even if the water is not needed in the middle process. It is not easy to manipulate the faucet in the presence of foreign matter, and it is usual that the water supply state is maintained and used as it is.
This results in a considerable amount of unnecessary waste of water.
According to the conventional registration utility model No. 0344251 (power-saving type electromagnetic-energy-saving water-saving machine), a power-saving operation control circuit having a microcontroller mounted inside a casing of a small coffee cup size, a noncontact type sensor which is easy to use, The present invention provides a power saving type electromagnetic energy saving water saving device which can be installed directly on any pipe or faucet for controlling the flow of water by providing a ball check valve assembly without using the ball check valve assembly, .
The power saving electromagnetic-energy-saving water-saving machine includes a ball check valve assembly and a conduit opening / closing drive assembly for selectively limiting the flow of water through the ball check valve assembly. The control valve value Vs ), Switch signal values corresponding to switch opening and closing of the switch, and driving of the motor corresponding to the pull-up signal or the ground signal of the sensor section, thereby reducing power consumption, size, and ease of use.
However, since the water-saving period is installed directly outside the sink such as a faucet, the water-saving period is not so good, and the water-saving sensor is installed too close to the radius of use of the user. Therefore, There is a problem that it may cause malfunction by sensing the operation, and there is a problem that the water-saving machine installed to protrude to the outside can be easily damaged by external physical impact.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a water-saving machine installed in a sink, comprising a control box installed at one of an intermediate portion and an end portion of a pipe for controlling supply or blocking of water, And a sensing device connected to the human body.

Also, a user confirmation sensing means is provided at the inner upper end of the sink for checking whether the user is close to the sensing device to prevent a malfunction, and is connected to the control box.
Here, the user confirmation sensing means may be any one of an infrared sensor and an ultrasonic sensor.
