Description

Valve for water saving

The present invention relates to a water-saving valve, and in particular, to control the discharge amount of hot water and cold water at the same time, for water-saving that can prevent the backflow of water (mixed water) mixed with hot water and cold water generated due to the shut off of the valve It is about a valve.

Due to the recent lack of precipitation due to extreme weather, water pollution due to environmental pollution, and lack of drinking water due to inadequate water waste, Korea is currently classified as a water shortage country designated by the International Institute for Population and Behavior (PAI), a subsidiary of the UN. As a result, there is a situation that warns of the seriousness of the lack of drinking water sources, and thus, there is an urgent need for a method for saving such drinking water sources.

Accordingly, the present inventors also have patent application No. 10-2003-0029664, "water saving foot valve" and patent application No. 10- to efficiently save unnecessary drinking water sources at home and increase convenience of users. 2003-0043958, such as "water saving valve" has been filed, in addition to a variety of water-saving foot valve has been used in the draft.

However, all the conventional water-saving valve is installed at the lower end of the sink (A) as shown in Figure 1 is configured to be connected to the water valve (C), wherein the cold and hot water mixer (M) is formed at the bottom of the water valve Cold water and hot water flowing from the cold and hot water supply pipe (B) is mixed first, and passed through the water-saving valve (1) through the mixed water inlet hose (D), and then again through the mixed water discharge hose (E) Connect to valve (C).

Therefore, the conventional water-saving valve 1 functions as a device for controlling supply and shutoff of the mixed water. When the water-saving valve 1 is blocked, the mixed water mixed inside the cold / hot water mixer M is relatively water pressure. The weak cold and hot water supply pipe (B) is a problem that is discharged back, which causes the hot water is introduced into the cold water supply pipe is difficult to maintain a constant temperature.

Thus, the conventional water-saving valve (1) is a two-spherical type with only one inlet and the mixed water outlet respectively, so that the hot water and cold water can not be separated and controlled, and eventually, to separate the hot water and cold water, It has a closed end that requires two valves.

In addition, the domestic water pipes are all the same, so if the cold and hot water supply pipe (B) can be connected to the cold / hot water mixer (M) after passing through the water-saving valve, it is possible to connect with only one connection port, but the conventional water-saving valve (1 ) Has a structure in which the cold and hot water supply pipe (B) is first passed through the cold and hot water mixer (M), and then connected to the water-saving valve, so that the connection port is different from manufacturer to manufacturer, and therefore, the connection port connected to the cold and hot water mixer (M) also has to be varied. In this case, the water-saving valve installer has a closed end to be provided with all kinds of connection ports.

Therefore, the present invention was devised to solve the disadvantages of the conventional water-saving valve as described above, the present invention is to use a four-necked ceramic cartridge type valve so that the inlet and outlet of hot water and cold water are separated, respectively, A water channel oil tool that can open and close the water and cold water channels at the same time is connected to the shaft gear so that the rotational force of the motor is transmitted to the shaft gear, and the shaft gear transmits the torque through the rotation shaft formed on the water tool. Therefore, to provide a water-saving valve that can control the opening and closing of the channel.

Referring to the configuration of the subject innovation in detail as follows.

2 is an exploded perspective view for showing the configuration of the present invention, the water-saving valve 10 of the present invention is the case 100, and the valve housing 300 is coupled to the case by the valve fixture 310 and And, the ceramic cartridge type valve 200 is built in the valve housing coupled to the valve fixing cap 320, and the valve 200 is built in the rotatable rotatable to open and close the channels of hot and cold water at the same time, A waterway oil tool 211 having a rotating shaft 210 at the rear, an axial rotating gear 330 to which the rotating shaft 210 is fitted and coupled, and a motor gear 340 for rotating by transmitting a rotating force to the rotating shaft gear. ) And the motor 350.

At this time, the configuration of the axial rotation gear 330 and the motor gear 340 may be composed of a variety of known power transmission devices, such as gears, chains, belts, etc. In the present invention, the efficient space arrangement of the motor and the transmission of strong rotational force Bevel gears were used for this purpose.

At this time, the motor 350 is turned on and off by a control circuit (not shown), and the control circuit is provided with a manual switch and a load sensor so that forward rotation or reverse rotation, stop, etc. may be possible by a user's switch operation. In addition, in order to prevent the user's convenience and damage to the motor, when the rotation of the waterway oil supply tool 211 is completed and the motor can no longer rotate, the overload generated at this time may be sensed so that the motor is turned off. The switch may be made of a foot switch operated by the foot for the convenience of the user.

As described above, the water-saving valve 10 of the present invention uses a four-hole-type ceramic cartridge type valve 200 so that the inlet and outlet of the hot water and the cold water are separated, as shown in FIG. The cold water inlet 212b is provided at the bottom, and the hot water and cold water outlet 212c are formed at the top, respectively.

Therefore, when the waterway oil tool 211 having the induction groove 211a on the front is rotated by 90 ° by the motor, the induction groove 211a also rotates by 90 ° to form a waterway, and when the opposite direction is rotated, It will work.

In this case, when the waterway tool 211 rotates 180 ° or 360 °, it is not easy to open and close the waterway, so a means for allowing the waterway tool to be rotated only within a range of 90 ° is required. It was to have a control member. The rotation angle adjusting member has a locking jaw 331 protruding in the range of 1/4 on the inner circumferential surface of the axial rotation gear 330, and a locking projection 361 fitted to the rear of the axial rotation gear 330. It consists of a rotation angle adjustment unit 360 having a.

Therefore, the axial rotation gear 330 can be rotated only within the range that the locking step 331 is not caught by the locking projection 361 of the rotation angle adjustment hole 360, the end of the waterway tool 211 is rotated by the axial rotation gear ) Is rotatable only within the range of 90 °. At this time, the rotation angle adjustment unit 360 is coupled by a screw 363 to the rear of the casing.

The water-saving valve 10 of the present invention may be operated by electric driving as in the motor as described above, but may be provided with a manual driving member to operate even when the supply of electricity is cut off. .

The configuration of the manual drive member for this is as follows.

In other words, the spring 370 is built into the rotation angle adjustment device 360, and the elastic force acts by the spring and the manual rotation hole 380 having a rotation knob 381 and the rotary shaft interpolation groove 382 Is done.

Therefore, the rotary shaft 210 of the waterway oil tool 211 penetrating through the through hole 362 of the rotation angle adjusting device 360 is rotated because the manual rotary hole 380 is pushed backward by the spring 370 at normal times. However, when the user needs to drive manually, if the user pushes the manual rotating tool 380 forward, the rotary shaft 210 is inserted into the rotary shaft interpolation groove 382, and the user rotates in the state. When the 381 is rotated, the channel 210 is also rotated while the rotary shaft 210 rotates, thereby opening and closing the channel.

At this time, the rotation handle is exposed to the outside of the case so that the user can be easily gripped through the through hole 140 of the case, the body of the manual rotating hole 380 that is not exposed is formed slightly larger than the diameter of the through hole 140 By doing so to prevent the manual rotation sphere 380 is separated from the case (100).

As such, the present invention is excellent in hermeticity and uses a four-necked ceramic cartridge type valve in which the inflow and outflow of hot water and cold water are separated from each other, but by forming a waterway oil tool to open and close the water and cold water channels simultaneously. It is possible to prevent the mixed water backflow into the cold and hot water supply pipe.

In addition, the present invention is configured so that the cold and hot water supply pipe is passed through the water-saving valve first, and then connected to the cold and hot water mixer, so that the piping work is easy, and the length of the pipe can be minimized, so that a very economical installation of the water-saving valve is possible.

In addition, the present invention is a very useful design that can expect a variety of effects, such as the inconvenience of having to install a separate mixed water inlet hose and discharge hose according to the size of the water valve, the speed of installation work and the reduction of processing cost.
