The present invention relates to an automatic control device for cold and hot water pressure so as to maintain a constant discharge of cold or hot water discharged through a mixer for controlling cold and hot water discharge when using hot or cold water simultaneously in a bathroom and a kitchen of a home. .

More specifically, it is installed inside the mixer to control the discharge of cold and hot water, and maintains the constant cold and hot water discharged through the mixer even when cold or hot water is used in other places where the mixer is connected by the same pipe. It relates to an automatic control device for cold and hot water pressure.

In general, the faucet used in homes, apartments, or offices are supplied with different pipes for cold water and hot water, and the mixed water mixed with cold and hot water is discharged through the mixer of the discharge port. That is, since the valve for selecting cold water or hot water is rotatably installed in the mixer, hot water is discharged when the user rotates the valve toward hot water, and conversely, cold water is discharged when the valve is rotated toward cold water.

As mentioned above, if hot water or cold water is used in different places where the mixer is connected by the same piping while selecting and using cold water or hot water according to the user's requirements (for example, using hot water in the bathroom of a house, , At the same time refers to the case of using hot water in the kitchen), the pressure of the corresponding pipe used is instantaneously experienced a sudden increase in the amount of cold water or hot water discharge.

In detail, when a user uses hot water in the bathroom when another person uses hot water at the same time in the kitchen, the pressure of the hot water side pipe drops momentarily, the hot water supply is reduced, while the unused cold water side pipe The pressure is relatively higher than the pressure of the hot water pipe, thereby increasing the amount of cold water supplied.

On the contrary, when cold water is used elsewhere, the cold water supply pressure decreases momentarily, and thus the amount of cold water is reduced, whereas the pressure of the unused hot water pipe is relatively higher than the pressure of the cold water pipe. Is increased.

At this time, the elastically deformed diaphragm 10 does not return immediately to the initial position even when the pressure of the hot water or cold water is the same, it takes a predetermined time to maintain the left and right balancing. For this reason, cold water or hot water may not be discharged in a timely manner according to a user's demand, and thus, inconvenience may be taken.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, which are intended to describe in detail enough to enable those skilled in the art to easily practice the invention, and therefore It does not mean that the technical spirit and scope of the present invention is limited.

As shown in Figure 2 to 4, the cold, hot water pressure automatic control apparatus according to the present invention, the hot water inlet 100 and the cold water inlet 101 is formed and the hot, cold water outlet 102 is formed ( In the cold and hot water pressure regulating device comprising a 103, a cold and hot water pressure adjusting means which is installed in the main body 103 and controls the cold and hot water discharge when the cold and hot water pressure changes,

The cold and hot water pressure control means described above,

The hot water inlet 104 and the hot water inlet hole 105 communicating with the hot water inlet 100 are radially formed on the left and right sides of the first partition 106, and

Cold water inlet 108 and the cold water inlet hole 109 communicating with the cold water inlet 101 is formed in the radial direction on the left and right sides of the second partition (110) and,

A diaphragm 112 which divides and partitions the hot and cold water supply units 107 and 111,

Through-holes 106a and 110a formed in the diaphragm 112 and formed in the first and second partitions 106 and 110 according to the hot and cold water pressure changes introduced through the hot water inlet 104 and the cold water inlet 108. Plungers 115 are formed at both ends of the piston (113, 114) for opening and closing the, respectively,

An elastic member installed outside the plunger 115 to prevent the plunger 115 from flowing in the radial direction of the plunger 115 which is moved according to the inflow of the hot and cold water through the hot water inlet 104 and the cold water inlet 108 ( 116).

At this time, the elastic member 116 is a cone-shaped compression coil spring, a dish-shaped spring, a cylindrical compression coil spring can be used, of course.

In the drawings, reference numeral 117 denotes a thermostat.

Hereinafter, with reference to the accompanying drawings an example of the use of the automatic control device for cold, hot water pressure according to the present invention will be described in detail.

As shown in FIG. 4, when the mixing ratio is determined by the user to determine the mixing ratio of hot water and cold water, hot water supplied from the outside is introduced into the main body 103 through the hot water inlet 100, and the cold water is the cold water inlet. Since it flows into the main body 103 through 101, hot water and cold water are balanced with each other, and the constant water pressure and quantity are discharged through the cold water outlet 102.

At this time, when cold water or hot water is used in different places where the mixer is connected by the same pipe, that is, when hot water is used in the bathroom of the house and hot water is used in the kitchen at the same time, the pressure of the hot water supply unit 107 is increased. Since it is relatively lower than the cold water supply 111 side, the amount of cold water flowing into the main body 103 through the cold water inlet 101 is larger than the amount of hot water flowing into the main body 103 through the hot water inlet 100. do.

At this time, since the diaphragm 112 of the elastic body that divides and partitions the hot water supply unit 107 and the cold water supply unit 111 loses balance, the plunger 115 is also shown in FIG. It is moved upward and leftward.

For this reason, the opening amount of the through-hole 106a formed in the 1st partition 106 mentioned above increases, and the through-hole 110a formed in the 2nd partition 110 is closed by the piston 114 on the contrary. Therefore, since the amount of hot water introduced into the hot water supply unit 107 is supplemented, it is possible to prevent the sudden increase in the amount of cold water supplied.

On the other hand, in the case of using lukewarm water mixed with hot and cold water by operating a mixer, the diaphragm 112 is returned to the initial position by the elastic restoring force due to the pressure of hot water and cold water flowing into the main body 103. Passed through the through holes (106a, 110a) formed in the first and second partitions (106, 110) by the pistons (113, 114) formed at both ends of the plunger 115 to maintain the flow into the hot water supply unit 107 and the cold water supply unit 111 The amount of hot and cold water can be adjusted.

As such, when the plunger 115 is moved in the axial direction by the elastic deformation of the diaphragm 116 due to the hot and cold water pressure flowing through the hot and cold water inflow holes 104 and 108, the elasticity is installed outside the plunger 115. It is possible to prevent the plunger 115 from flowing radially by the member 116. As a result, it is unnecessary to form a cylinder for accommodating the reciprocating pistons 113 and 114, thereby simplifying the structure of the hot and cold water adjusting means, thereby reducing the cost. In addition, the response of the plunger 115 according to the cold and hot water pressure change can be improved, thereby having reliability.

As described above, the cold, hot water pressure automatic control device according to the present invention has the following advantages.

Even when cold water or hot water is used in different places where the mixer is connected by the same pipe, the user can be provided with convenience by maintaining a constant cold and hot water discharged through the mixer.

In addition, when moving in the axial direction by the diaphragm elastically deformed according to the pressure change of the hot and cold water, it is prevented from flowing in the radial direction of the plunger by the elastic member, thereby simplifying the structure of the cold and hot water pressure control means to reduce the cost It is reliable and can improve the plunger responsiveness so that hot or cold water can be used in a timely manner according to user requirements.
