Description

  The present invention relates to a water faucet, and more particularly to a water faucet provided with a push button.

  Conventionally, there has been known a faucet that can be selectively changed to other water discharge amounts such as small water discharge and large water discharge in addition to the water discharge amount during normal water discharge. For such a water faucet, for example, a flow rate adjusting means such as a disk valve is attached in the middle of the flow path, and the opening / closing amount of the disk valve is adjusted in advance so that the discharge according to the user's request or specification mode is achieved. Some are provided so that the amount of water can be obtained (see, for example, Patent Document 1).

JP 2004-92069 A (FIG. 1)

  In such a faucet, it is possible to change to a desired water discharge amount, but for the change, it is necessary to adjust the water discharge amount in advance by a flow rate adjusting means. Therefore, it is difficult to change the water discharge amount easily and quickly, and it is also difficult to change the water discharge amount frequently. For this reason, even if it is a usage mode which requires a small amount of water discharge, a large amount of water discharge is often performed, and the water-saving effect of the water faucet cannot be enhanced.

  The present invention solves the above-described problems of the conventional water faucet, and enhances the water-saving effect by enabling the water discharge amount to be changed easily and quickly by operating the push button. The purpose is to provide a faucet that can be used.

  In order to solve the above problems, means taken by the present invention will be described below. The water faucet of the present invention is a water faucet provided with a water discharge part that discharges the hot water or water supplied from at least one of the hot water supply pipe or the water supply pipe to an appropriate amount, and the hot water or water from the water discharge part A first on-off valve for starting, stopping and adjusting the discharge amount of the fuel, first on-off valve operating means for operating the first on-off valve, and communication between the first on-off valve and the water discharge portion A first flow path equipped with a constant flow valve and a second open / close valve that is connected in communication between the first open / close valve and the water discharge unit and that can be opened and closed with a push button The first flow path and the second flow path are connected to each other on the upstream side of the water discharge section (Claim 1).

  Since the first flow path and the second flow path are connected in communication on the upstream side of the water discharge section, when the second open / close valve is closed, the water discharge at a predetermined flow rate regulated by the constant flow valve is performed. When the second on-off valve is opened, water discharge can be performed in combination with the predetermined flow rate of the constant flow valve and the water discharge amount from the second flow path. it can. In this manner, small water discharge and large water discharge can be selectively performed from the water discharge unit. Since the opening and closing of the second on-off valve can be operated by a push button, such a small water discharge and large water discharge selection operation does not require an operation such as a rotary handle or a lever handle. It can be performed very simply and quickly.

  In the present invention, the “water discharge portion” refers to all members that discharge hot water and water such as a water discharge port and a shower head. The “push button” includes a wide range of buttons that can be operated by a simple push operation or contact operation.

  Moreover, the above-described water faucet may be applied to a hot and cold water mixing faucet (claim 2).

  Moreover, it is good also as providing a constant flow valve so that attachment or detachment is possible with respect to a water tap main body (Claim 3).

  By making the constant flow valve detachable, the constant flow valve can be easily replaced, and the flow rate during small water discharge can be easily changed.

  As described above, since the selection operation of large water discharge or small water discharge can be easily and quickly performed by the push button as described above, it is possible to switch to small water discharge frequently and enhance the water-saving effect of the faucet. Can do.

  Next, an embodiment of the water tap of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the water faucet 1 of the present invention is installed on a bathroom vanity 2. The vanity table 2 includes a cabinet 3 at the bottom and a dresser 5 with a mirror door 4 attached to the front. A wash bowl 6 is installed in the upper part of the cabinet 3, and the faucet 1 of the present invention is built in the lower part of the dresser 5 in the upper part of the wash bowl 6. In addition, the faucet of the present invention can be applied to a faucet used in other installation locations such as a faucet installed in the bathroom, kitchen or outdoors, in addition to being used in the vanity table 2 as described above.

  As shown in FIG. 2, the faucet 1 is installed on the front side of the panel 7 below the dresser 5 so that a part of the structure is exposed. Specifically, a single lever type operating handle 8 corresponding to an example of the “first opening / closing valve operating means” of the present invention is attached near the right end of the panel 7. A push button 9 for switching the amount of water is attached. In addition, a pull-out shower head 10 corresponding to an example of the “water discharge portion” of the present invention is detachably attached to the lower portion of the center of the panel 7.

  Next, the details of the water tap 1 will be described with reference to FIG. The water faucet 1 is connected in communication with a hot water supply pipe 12 and a water supply pipe 13 drawn from the back side of the wall surface 11 on the back of the vanity unit 2. The water faucet body 20 is provided with a temperature control valve 22, and appropriate amounts of hot water and water supplied from the hot water supply pipe 12 and the water supply pipe 13 are mixed and set to a desired temperature by the operation handle 8 described above. Further, the faucet body 20 has a built-in stop water flow rate adjustment valve 23 corresponding to an example of the “first on-off valve” of the present invention. Similarly, the operation handle 8 can adjust the stop water and the flow rate. Done.

  A first flow path 26 and a second path 30 are connected to the downstream side of the temperature control valve 22 and the discharge water flow rate control valve 23. The first flow path 26 and the second flow path 30 are once branched from the flow path 24 connected to the temperature control valve 22 and the discharge water flow rate control valve 23, respectively, and are gathered together again in the flow path 34 reaching the shower head 10 to be in communication connection. Has been.

  A constant flow valve 28 is attached in the middle of the first flow path 26. The constant flow valve 28 limits the flow rate of the first flow path 26 within a predetermined range, and the discharged water flow rate determined by the operation of the discharged water flow rate adjustment valve 23 by the operation handle 8 is limited by the constant flow valve 28. When the water discharge flow rate is exceeded, the flow rate of the first flow path 26 is limited to a predetermined value or less. In this example, the constant flow valve 28 has a limited flow rate of 5 liters per minute, but a constant flow valve with another limited flow rate may be used. Further, the constant flow valve 28 is detachably provided in the first flow path 26, and can be easily changed to a constant flow valve with another limited flow rate.

  A second opening / closing valve 32 for opening and closing the second channel 30 is provided in the middle of the second channel 30. The second opening / closing valve 32 is an electromagnetic opening / closing valve, and is opened and closed by a push operation of the push button 9. Therefore, the opening / closing operation of the second on-off valve 32 can be performed without requiring a large operation like a lever handle. Each time the push button 9 is pressed, the opening / closing operation of the opening / closing valve is alternately performed.

  Downstream end portions of the first flow path 26 and the second flow path 30 are gathered and connected to the flow path 34. The shower head 10 is connected to the downstream end of the flow path 34.

  The faucet 1 configured as described above can be used as in the following example. First, an opening operation is performed in advance by the push button 9 so that the second on-off valve 32 is opened at the time of large water discharge, and water discharge set to an arbitrary hot water temperature is performed from the shower head 10 by the operation handle 8. Since the shower head 10 is detachably attached, the shower head 10 may be used like a water spout while being attached to the lower portion of the panel 7 or may be detached from the panel 7 and used as a hand shower.

  On the other hand, when using with small water discharge, it operates so that the 2nd on-off valve 32 may be closed by pushing operation of the push-type button 9. FIG. In this operation, it is possible to switch to small water discharge by a slight operation of pushing the push type button 9. On the contrary, even when switching from small water discharge to large water discharge, a slight operation is sufficient.

  Therefore, when the small water discharge is sufficient, the large water discharge can be easily and quickly switched, and the water-saving effect of the water tap 1 can be enhanced. Specifically, for example, when washing your contact lenses after washing your hands with large water discharge, when you wash your hair quickly after washing your hair in the bathroom, or just before leaving the bathroom after taking a bath It is possible to frequently switch to small water discharge when flowing the body. In addition, once the water discharge is stopped, it takes time to reach the set water temperature when the water discharge temperature starts to drop again and starts again. If it is necessary to switch to small water discharge and not lower the hot water temperature and then switch to large water discharge again, large water discharge at a predetermined hot water temperature can be used immediately, and the convenience of the water tap 1 can be improved. .

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the gist of the present invention. For example, the water tap 1 described above is a hot water / water mixing tap, but the present invention is not limited to this, and the present invention can also be applied to other types of water taps such as a single tap. In the above-described water faucet 1, only the shower head 10 is provided as a “water discharge portion”, but a “water discharge portion” such as a water discharge port or a plurality of “water discharges” such as a shower head and a water discharge port are provided. It can also be applied to a faucet provided with a “part”.
