Description

Water saving device for sink

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.

Korean Registered Utility Model No. 0344251

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.

The plate and the human body are spaced apart from each other by the dielectric due to the proximity of the person, and the capacitance Cf is formed through the plate and the human body, and is configured in parallel with the Cr so that the charge / discharge time change of the capacitance due to the increase of the total capacitance So that the human body can be detected.

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.

FIG. 1 is a schematic view showing a state in which a water-saving type water-saving device according to the present invention is installed in a sink, FIG. 2 is a diagram showing a schematic configuration of a sensing device for a water- FIG. 4 is a schematic view showing a user confirmation sensing unit as another embodiment of the water-saving unit for a sink according to the present invention.

The present invention relates to a water-saving machine installed in a sink (10), comprising a control box (30) installed at one of an intermediate portion and an end portion of a pipe for controlling supply or blocking of water, And the sensing device 100 senses the foot 51 of the human body 50 in proximity to the lower end of the sink 10 so as to be operated, .

One end of the touch sensor IC 110 is connected to the first connection part 111 of the touch sensor IC 110, and the other end of the touch sensor IC 110 is connected to the touch sensor IC 110. The sensing device 100 includes a touch sensor IC 110 for measuring and processing the charge / A load capacitance Cr 120 connected to the second connection part 112 and the ground GND of the sensor IC 110 and a conductive plate 130 having one side connected to the first connection part 111, And a dielectric 140 connected to the opposite side of the first connection part 111 of the plate 130.

The plate 130 and the human body 50 are spaced apart from each other by the dielectric 140 due to the proximity of a person and a capacitance Cf 150 is formed through the plate 130 and the human body 50. The capacitance Cf (150) is configured in parallel with the Cr (120), thereby measuring the charge / discharge time variation of the capacitance due to an increase in the total capacitance, thereby sensing the human body (50).

A user confirmation sensing means 200 is provided at the upper side of the inside of the sink 10 so as to prevent a malfunction by checking whether the user is close to the sensing device 100 and is connected to the control box 30, The user confirmation sensing means 200 may be any one of an infrared sensor and an ultrasonic sensor.

In addition, as a method of supplying water by sensing the human body 50 in proximity to the sensing device 100 and controlling the control box 30,

Storing an initial load capacitance Cr (120) value (SlOO);

Measuring a charge / discharge time of the touch sensor IC 110 in a state where the human body is not in proximity to the sensing device 100 (S200);

A step (S300) in which the human body (50) approaches the sensing device (100) to operate the water supply device;

Measuring a charge / discharge time of the touch sensor IC 110 in a state where the human body is close to the sensing device 100 (S400);

The electrostatic capacity charging / discharging time (S200) in the state where the human body is not in proximity to the sensing device (100) in the touch sensor IC (110) is compared with the electrostatic capacity charging / discharging time (S400) 50) (S500);

And operating the water supply device by controlling the control box 30 (S600).

The process of using the present invention will now be described.

As shown in FIG. 1, in order to control the supply or cutoff of water, a control box 30 installed at one of the middle or end of the pipe and a wire connected to one side of the control box 30 to detect the human body 50 And the sensing device 100 is configured at the lower inner side of the sink 10 so that the sensing device 100 senses the foot 51 of the adjacent human body 50 and is operated.

It is preferable to configure the inside of the rack base 40 of the countertop 10 where the feet 51 can be easily positioned when the kitchen sink 10 is used for cooking or washing dishes.

This is because when a person is working in a kitchen such as a kitchen sink or a dish in a sink 10, he usually moves a lot of hands. In this case, the conventional faucet 20, In the water saving period, there is a problem of malfunction due to unintentional sensing by the hand.

However, according to the present invention, the foot 51 of the human body 50 is brought close to the sensing unit 160 of the sensing device 100 to supply water, thereby making it possible to use the hand without fear of malfunction.

2, the sensing device 100 includes a touch sensor IC 110 for measuring and processing the charging / discharging time of the electrostatic capacity, and a second connection part 111 for connecting the first connection part 111 of the touch sensor IC 110 And a load capacitor Cr 120 connected to the second connection part 112 and the ground GND of the touch sensor IC 110 on one side and the first connection part 111 A conductive plate 130 and a dielectric 140 connected to the opposite side of the first connection part 111 of the plate 130.

The plate 130 and the human body 50 are spaced apart from each other by the dielectric 140 due to the proximity of a person and a capacitance Cf 150 is formed through the plate 130 and the human body 50. The capacitance Cf (150) is configured in parallel with the Cr (120), thereby measuring the charge / discharge time variation of the capacitance due to an increase in the total capacitance, thereby sensing the human body (50).

Here, in the case of the sink 10 on which the present invention is installed, the mop holder 40 can be used instead of the dielectric 140.

The capacitance of the sensing device 100 is constituted by the load capacitance Cr 120 before the human body 50 approaches the sensing device 100. The human body 50 is placed on the sensing device 100, The capacitances Cf 150 are formed in parallel with the Cr 120 to increase the capacitance of the sensing device 100 by Cf 150. [

The touch sensor IC 110 measures the charge / discharge time of the capacitance Cr 120 before the human body 50 is brought close to the human body 50 and measures the capacitance Ctotal (= Cr + Cf) Discharging time is measured and compared to detect the change of the electrostatic capacity, and the proximity of the human body 50 is confirmed.

Here, the capacitance C =

Figure 112015036645026-pat00001
(A / t); (
Figure 112015036645026-pat00002
= Relative dielectric constant of the material between the plates, A = area of the plate, and t = distance between the plates)

The capacitance of the sensing device 100 increases as the area of the plate 130 increases, and as the human body 50 gets closer to the sensor, the capacitance increases and the sensing efficiency becomes better.

Also, depending on the material of the dielectric 140 formed between the plate 130 and the human body 50, it is affected by the capacitance, so that it is possible to increase the detection efficiency by changing the material of the base pan 40 will be.

It is preferable that the plate 130 of the sensing device 100 is arranged in the vertical direction adjacent to the base plate 40 on the inner side of the base plate 40.

This is because when the plate 130 is constructed to be horizontal on the floor from the inside of the baseboard 40, the value of the capacitance Cf 150 generated even when the feet 51 are close to feed water is significantly reduced, So that the sensing device 100 may not operate.

That is, the capacitance C =

Figure 112015036645026-pat00003
(A / t); (
Figure 112015036645026-pat00004
= Relative dielectric constant of the material between the plates, A = area of the plate, and t = distance between the plates)

The capacitance Cf 150 due to the feet 51 adjacent to the plate 130 is greater than the capacitance of the plate 130 corresponding to the area A of the electrode plate when the plate 130 is configured to be laid flat on the floor, (Area of the electrode plate) is remarkably reduced due to the area of the thin side surface rather than the wide horizontal surface of the sensing device 100, so that the capacitance Cf 150 is remarkably reduced and the sensing efficiency of the sensing device 100 is lowered.

If the plate 130 is formed in a space outside the mop base 40, the sink 10 is usually located indoors so that the user can work with the bare feet in the kitchen. As a result, The capacitance Cf 150 by the human body 50 is not formed and the sensing device 100 may not be operated.

The plate 130 of the sensing device 100 is arranged in the vertical direction adjacent to the mover receptacle 40 from the inside of the mop receptacle 40 (the effect of reducing the distance between the electrode plates) (The effect of increasing the area of the electrode plate).

A user confirmation sensing means 200 is provided at the upper side of the inside of the sink 10 so as to prevent a malfunction by checking whether the user is close to the sensing device 100 and is connected to the control box 30, The user confirmation sensing means 200 may be any one of an infrared sensor and an ultrasonic sensor.

That is, by configuring the sensor of the sensing device 100 at the lower end of the sink 10, pets such as a mouse, a dog, and a cat can be easily accessed, and malfunction of the sensing device 100 can occur.

However, by configuring the user confirmation sensing means 200 at a position above the size of a pet such as a mouse, a dog, or a cat on the inner upper side of the sink 10, a rat or a pet may approach the sensing device 100, It is possible to check again whether the presence of the user proximate to the sensing device 100 is detected by the user confirmation sensing means 200 to prevent the water supply device from malfunctioning.

Here, the user confirmation sensing means 200 may be configured through a normal infrared sensor or an ultrasonic sensor.

The operation of the present invention will now be described with reference to the flowchart.

As shown in FIG. 3, the initial value of the initial load capacitance Cr 120 in the absence of the human body 50 is stored in the sensing device 100 in the initial setting step S100.

The capacitance charge / discharge time for the load capacitance Cr 120 in the state where the human body is not in proximity to the sensing device 100 in the touch sensor IC 110 is measured (S200)

When the human body 50 approaches the sensing device 100 in order to operate the water supply device S300, the capacitance Cf 150 is formed through the plate 130 of the sensing device 100 and the human body 50 And the capacitance of the sensing device 100 becomes Ctotal '= Cr (120) + Cf (150) by being configured in parallel with the Cr 120.

The electrostatic capacity charge / discharge time is measured in the total capacitance Ctotal '= Cr (120) + Cf (150) in a state where the human body is in proximity to the sensing device 100 in the touch sensor IC 110 (S400)

The electrostatic capacity charging / discharging time (S200) in the state where the human body is not in proximity to the sensing device (100) in the touch sensor IC (110) is compared with the electrostatic capacity charging / discharging time (S400) And confirms the proximity of the human body 50 through the magnitude of the charging / discharging time difference (S500).

If the magnitude of the charging / discharging time difference is larger than the sensitivity value preset in the touch sensor IC 110, the proximity of the human body 50 is confirmed and the water supply device is operated by controlling the control box 30. (S600)

However, when the user does not need a water supply while working on a kitchen such as cooking or washing dishes and the foot 51 is out of the detection distance allowable range, the size of the charging / discharging time difference is preset in the touch sensor IC 110 The sensing device 100 determines that the human body 50 is not in proximity and controls the control box 30 so as not to operate the water supply device.

In such a configuration, the sensing device 100 senses the feet 51 and operates so that there is no problem that the sensing device 100 may malfunction due to a wrong hand moving when cooking or washing dishes .
