Abstract

The present invention relates to a faucet for a kitchen, a bathroom, and a sink is a device for facilitating tap water saving by facilitating the temporary opening and closing of tap water during the use of tap water.

In general, the faucet has to operate the switchgear every time to open and close the water output and the water temperature again, there is a cumbersome when you want to open and close frequently temporarily to save tap water during use. Therefore, in the present invention, the tap water can be opened and closed when the hot water and cold water are operated up and down after the opening and closing device (first opening and closing device) for controlling the amount of hot and cold water discharged to facilitate the temporary opening and closing of the tap water. Install the secondary switchgear (6) of the type.

In addition, in order to prevent the reverse flow of tap water that may occur when the switchgear is installed in duplicate, install a non-return valve (1, 2). That is, when the primary switchgear 5 closes only the secondary switchgear 6 in an open state, the hot water pipe 13 and the cold water pipe 14 are connected to each other, so that the water pressure difference between the two pipes is increased. When tap water backflow occurs (Figure 2), when the second switchgear is opened again, the amount of hot or cold water flows out as the amount of backflow, which may not only be unpleasant to use but also cause an accident. In addition, since the tap water metering device continues to operate even while the tap water flows back, it installs a non-return valve of the present invention to prevent it.

The present invention relates to a faucet for a kitchen, a bathroom, and a sink, the object of the present invention is to facilitate the temporary opening and closing of the tap water during the use of the tap water to promote tap water saving.

In general, when looking at the structure of the faucet, ① The hot water switchgear and the cold water switchgear installed respectively to adjust the amount of water output by adjusting the amount of water discharged ② The hot water switchgear and cold water switchgear tied in a single unit with the output and water temperature ③ The first switchgear (refers to the hot water switchgear and cold water switchgear) after installing the second switchgear to open and close the tap water combined with hot water and cold water has a double switchgear device. .

Looking at the problems of the above method, first, the method of ①, ② above must be re-adjusted the amount of water and the water temperature by operating the switchgear every time opening and closing, so that the water volume and water temperature is kept constant, often to save tap water during use. When you want to open and close there is a cumbersome point.

In the method of ③, when the primary switchgear is opened and only the secondary switchgear is closed, the tap water backflow phenomenon occurs due to the pressure difference because the hot water pipe and the cold water pipe are in a connected state (Fig. 2). When the second opening and closing the device is open again, the amount of hot or cold water flows back as much as it is not only unpleasant to use, but may cause an accident. In addition, since the tap water metering device continues to operate while the tap water is refluxed, there is a problem in that the amount is accumulated even though the tap water is not actually used.

In addition, the methods of ①, ②, ③ above is rotated or the lever is operated up and down or left and right, it is inconvenient to open and close frequently while using tap water.

1. Water pipes flowing by joining hot and cold water after the primary switchgear (the device that controls the amount of hot and cold water output) to facilitate temporary tap water opening and closing to save tap water during use. Install a secondary switchgear that operates the pipe up and down).

2. To prevent tap water backflow that may occur when the primary switchgear is opened and only the secondary switchgear is closed, a non-return valve is installed in the hot water pipe and the cold water pipe, respectively.

1. Second opening / closing device: FIG. 1 and FIG. 10, 11, and 12, the secondary opening and closing device 6 is installed, but is formed by combining the first outlet pipe 7 and the second outlet pipe (8). The end portion of the first outlet pipe is formed in a cylindrical shape in the transverse direction of the first outlet pipe, and a portion thereof is cut off at the same time so as to insert the cylindrical portion of the second outlet pipe into the plug 11. . In addition, several grooves are dug in the cylindrical portion to form the first outlet pipe outlet 15. The inlet side of the second outlet pipe is cylindrically shaped to be in close contact with the inner wall of the cylindrical part of the first outlet pipe, and a plurality of grooves are dug to form the second outlet pipe inlet 9. The first outlet pipe outlet 15 and the second outlet pipe inlet 9 are recessed to open or close as the cylindrical portion of the first outlet pipe and the cylindrical portion of the second outlet pipe closely contact each other. To parse

2. Non-return valve: The non-return valve is installed in the hot water pipe and the cold water pipe as shown in Figs. 1, 5, 6, 7, and 8. The inner wall of the hot water pipe 13 and the cold water pipe 14 is provided with a groove into which the non-return valve rotation pin can be inserted to form a non-return valve rotation pin support groove 18 so that the non-return valve can be opened only in the direction of the tap water outlet. The non-return valve may be formed to prevent the reverse opening of the reverse jaw 19. The non-return valve is formed in close contact with the reverse opening prevention jaw 19 when it is closed so that no leakage occurs at the contact surface, and the non-return valve may be inserted into the support valve of the non-return valve rotation pin by making a check valve rotation pin on both sides of the valve. Combination of the non-return valve revolving pin 17 and the non-return valve revolving pin support groove 18 freely rotates so that the non-return valve can be naturally opened and closed by the flow of water with the rotary pin 17 as the axis. .

3. As an example of applying the above device, instead of operating the second outlet pipe up and down, the lever is mounted so that the lever can be opened and closed. That is, as shown in FIGS. 13, 14, 15, and 16, a cylindrical portion is formed in the middle of the discharge pipe in the horizontal direction, and the inlet 25 and the outlet 26 of the tap water are formed. The cylindrical opening and closing valve 23 with a lever 24 is inserted into the cylindrical portion and is coupled with a stopper 11. The inlet 25 and the outlet 26 are also formed in the cylindrical on / off valve to operate the lever up and down from the outside so that the tap water can be opened and closed as the cylindrical part of the outlet pipe is in close contact with the cylindrical on / off valve. do.

1. If you want to use tap water for the first time, open both the primary switchgear (hot water switchgear 3, cold water switchgear 4) and the secondary switchgear 6 as shown in FIG. . In this case, since both the non-return valves 1 and 2 open automatically due to the water pressure acting in the tap water outlet direction, there is no influence on the flow of tap water.

2. If you want to temporarily cut off the tap water to save tap water during use, push the second outlet pipe 8 upward as shown in Figure 12 and only the secondary switchgear 6 will close and the tap water will be cut off. It is convenient. In this case, since the hot water pipe 13 and the cold water pipe 14 are in a connected state, the tap water will continue to flow from the strong water pressure side to the weak water pressure side, but the check valve (1, 2) is installed so that this can be prevented. have. That is, as shown in FIG. 4, if the water pressure of the tap water is strong in the hot water pipe 13 side, the tap water will flow from the hot water pipe to the cold water pipe 14, in this case, Since the non-return valve 2 is closed, the flow of water stops. If the water pressure in the cold water pipe is strong, the flow of water stops on the same principle, so that no reverse flow of tap water occurs.

3. When the secondary switchgear 6, which was temporarily closed, is opened again by pressing the second outlet pipe 8 downward, the non-return valves 1 and 2, which are closed by water pressure, are opened and water is reopened. In this case, since the primary switchgear maintains the previous control state as it is, the amount of water output and the water temperature are the same as the previous state, which is convenient for use.

4. In summary, it is installed in the water outlet pipes (7, 8), which is a convenient position to operate the secondary switchgear (6), so that the tap water can be easily opened and closed during use, so that the tap water can be saved. By installing (1, 2), the side effects of tap water backflow, which may be caused by the installation of the secondary switchgear, were also prevented. Due to the combination of the above two devices, it is possible to temporarily open and close the tap water while maintaining the same amount of water output and water temperature, thereby achieving the tap water saving effect and at the same time, the convenience of use.
