Description

Automatic controlling system for water temperature and the volume of water}

The present invention relates to a water quantity and automatic temperature control device, and more specifically, the water supplied from the cold and hot water mixing faucet is used elsewhere to prevent cold water or hot water from suddenly changing due to sudden pressure change and The present invention relates to a water temperature automatic control device.

In general, faucets used in homes, apartments, offices, etc. are supplied with hot and cold water through different pipes, and are mixed and supplied through a mixer in front of the final discharge port.

The mixer is provided with a valve for selecting cold water and hot water, when rotating the valve to one side, hot water is discharged, when rotating to the opposite side, the cold water is discharged, if the valve is placed in the intermediate position of the cold and hot water mixed Water is to be discharged.

When washing or showering using such a faucet, the user adjusts the valve so that water having an appropriate temperature can flow out, so that it can be used in the most comfortable state.

However, if the water is used elsewhere during the adjustment and use as described above, the pressure of the pipe is lowered and suddenly only cold or hot water is discharged. It's quite embarrassing.

In particular, in the case of hot water is suddenly discharged has a problem that the burn due to the high heat is in contact with the user's body.

When hot water is used elsewhere, the supply of hot water decreases while the pressure of the hot water pipe is reduced, whereas the pressure of the unused cold water pipe is higher than the pressure of the hot water pipe and the amount of cold water is relatively high. Cold water is discharged;

If cold water is used elsewhere, the supply of cold water decreases when the pressure in the cold water pipe is reduced, whereas the pressure of the unused hot water pipe is higher than the pressure in the cold water pipe and the amount of hot water is relatively high. This is because water is discharged.

In the related art, there is no device or means for discharging water in a state controlled by the user in response to the pressure change of the cold and hot water pipes, and thus, the problems described above cannot be solved.

Therefore, the present invention is designed to solve the above problems, and installed in the middle of the pipe for supplying cold and hot water or inside the mixer, and using water in another place, even if there is a pressure change in one pipe, the temperature of the user controlled state The purpose of the present invention is to contribute to the user's convenience by allowing water to be discharged.

In the present invention, one of the pipes 10 of the cold water pipe 10 or the hot water pipe 11 is installed in the middle of the pipes 10 and 11 for supplying cold and hot water or inside the mixer 12 and uses water elsewhere. , 11) characterized in that it provides a water quantity and automatic temperature control device 20 to be discharged to the water in the temperature of the user adjusted state even if there is a pressure change.

The adjusting device 20;

Upper and lower sides of the inlets 21 and 22 installed in the pipes 10 and 11 or the mixer 12 to be connected to the pipes 10 and 11, and the outlet parts for discharging the cold and hot water. And a body 25 having 23 and 24.

The upper and lower portions of the inlet portions 21 and 22 and the outlet portions 23 and 24 formed in the body 25 may pass through the passages 26 and 27, and the flow of water may be blocked in the middle of the passages 26 and 27. The valve holes 30 and 29 so that the valves 28 and 29 can move horizontally. Have it.

The pressure chamber 31 is provided inside the passages 26 and 27, and a pressure plate 33 connected to the valves 28 and 29 and the fixing bar 32 is provided at the center of the pressure chamber 31. The pressure plate 33 is moved by the hot water so that the valves 28 and 29 can open and close the passages 26 and 27.

The diaphragm 35 is connected between the outer periphery of the pressure plate 33 and the inner wall of the pressure chamber 31 so that the pressure plate 33 can be easily moved by hydraulic pressure.

In the valve hole 30 on the pressure chamber 31 side, the pressure plate 33 may be moved to form a separate through hole to allow a pressure change, or to have a predetermined distance from the bottom of the valves 28 and 29.

Looking at the operating relationship of the present invention as described above;

By connecting the cold and hot water pipes 10 and 11 using the inlet parts 21 and 22 and the outlet parts 23 and 24 formed in the body 25 of the adjusting device 20, or the conventional mixer 12. Install and use inside.

In the normal state, the adjusting device 20 installed as described above has a uniform pressure in the passages 26 and 27 of the body 25, so that the pressure plate 33 of the pressure chamber 31 is positioned in the middle, The amount and temperature of hot water is constant.

However, when water is used elsewhere and the pressure on one side of the pipes 10 and 11 drops, the valves 28 and 29 move to block the passages 26 and 27 on the high pressure side and the pressure on the low side. By opening the passages 26 and 27, the amount and temperature of the water can be kept constant.

Looking at it;

When cold water is used elsewhere, the pressure of the cold water pipe 10 is lowered, thereby reducing the amount of water supplied to the controller 20, and since the pressure of the hot water pipe 11 maintains the same pressure as the initial state, the cold water pipe is Compared with (10), a relatively large amount of water is supplied.

Then, the hot water is in a state governing the pressure of the pressure chamber 31 to push the pressure plate 33 toward the cold water pipe 10, the valves 28 and 29 connected to the pressure plate 33 and the fixed bar 32. ) Is moved toward the cold water pipe (10).

As described above, the valves 28 and 29 move toward the cold water pipe 10 so that the valve 28 on the cold water pipe 10 side moves to the valve hole 30 to increase the opening degree, and the hot water pipe 11 side. The valve 29 of the can be separated from the valve hole 30 to block the passage 27 by reducing the amount of hot water is possible by maintaining the same pressure state.

In addition, when the hot water is used elsewhere, the pressure of the hot water pipe 11 is lowered, so that the amount of water supplied to the adjusting device 20 is reduced, and the pressure of the cold water pipe 10 maintains the same pressure as the initial state. A relatively large amount of water is supplied as compared to the hot water pipe 11.

Then, the cold water is in a state dominating the pressure of the pressure chamber 31 to push the pressure plate 33 toward the hot water pipe 11, the valves 28 and 29 connected to the pressure plate 33 and the fixed bar 32. ) Is moved to the hot water pipe (11).

As described above, the valves 28 and 29 move toward the hot water pipe 11 so that the hot water pipe 11 is moved. The valve 29 on the side moves to the valve hole 30 to increase the opening degree, and the valve 28 on the cold water pipe 10 side is separated from the valve hole 30 to block the passage 26. This will reduce the amount of hot water.

Although the valves 28 and 29 move in the process as described above to block the passages 26 and 27 on one side, the through-holes or valves 28 and 29 formed separately in the valve holes (pressure chamber direction) 30 on the blocked side. Since the pressure chamber 31 on the side blocked by the gap with the bottom surface may leak, the pressure plate 33 does not interfere with the movement.

When the pressure of one side pipe is lowered by using water elsewhere, the present invention as described above, the pressure plate is operated by the pressure of the normal pipe while the valve is interlocked to maintain the amount of water in the same state, the water temperature of the user adjusted state It can be maintained.

The present invention as described above is installed in the middle of the pipe for supplying cold and hot water or inside the mixer so that water can be discharged at a temperature controlled by the user even if there is a pressure change in one pipe using water elsewhere. It can contribute to the improvement of users' convenience.
