Description

[Detailed description of the invention] (Industrial field of application) This invention relates to improvement of a bathroom vanity.

(Prior Art) Conventionally, the washbasin of a bathroom vanity is provided with two cleaning nozzles, and the inner wall of the washbasin is cleaned with the cleaning liquid discharged from these two nozzles. There are those shown in Figures 1 and 3 of Publication No. 30379 (Figures 7A and 7B of the drawings of the present application). Briefly explaining FIGS. 7A and 7B above, the nozzle 62 for discharging cleaning liquid provided at the upper part of the inner wall surface of the washbasin 61 has a semicircular shape in a direction perpendicular to the diffusion part 63 that communicates with the tip of the flow path 65. This nozzle 62 supplies cleaning liquid to each flow path 65 by operating a separately provided operating knob 66, and this cleaning liquid passes through the flow path 65 and flows from the diffusion groove 64 to the washbasin 6.
The water is ejected in a semicircular shape into the washbasin 61 to clean dirt and attached foreign matter from the inner wall surface of the washtub 61. In the case of the above, since the cleaning liquid is discharged by rotating the handle using a pair of screws,
If you carelessly turn the handle too much, you will spray out more cleaning liquid than necessary, and the jet will flow out like a water curtain along the inner wall of the washbasin, wasting the cleaning liquid and staining the floor. Moreover, the diffusion grooves of each nozzle are only provided downward along the inner wall of the washbasin, so the cleaning liquid does not spread all over the inner wall of the washtub regardless of the water pressure level, which prevents dirt from spreading. There were some remaining flaws.

Additionally, if the drain pipe becomes clogged or the water suddenly stops while you are washing your face or washing your hair, sewage in the washbasin will enter the pipe through the nozzle's diffusion groove.
There was a risk that the water would flow back into the water supply source.

(Problem to be solved by this invention) The problem to be solved by this invention is that it is possible to wash the entire inner wall surface of the washbasin without any corners with a single spray of water, regardless of the level of tap water pressure. In addition, the purpose is to prevent sewage from flowing back into the water supply pipe from the washbasin in the event of a water outage or when the drain pipe is clogged.

(Means for solving the problem) The technical means taken by the present invention to solve the above problem is a water supply valve with a push button for discharging water on one side of the washbasin installed in the washstand. At the same time, one end of the water supply pipe is connected to the water supply valve, and the other end is connected to a branch part of the octopus piping that is piped along the outer wall of the washbasin, and from the branch part the water supply pipe is connected along the outer wall of the washbasin. At each end of branch piping extended in different directions,
A nozzle portion having a direct water hole opened linearly in the pipe extension direction and a lateral water hole opened in the pipe circumferential direction is provided, and each nozzle portion is passed through from the outer wall surface to the inner wall surface of the washbasin. The water supply valve is fixed to a washbasin so as to face from the outside to the inside through a plurality of mounting holes, and the water supply valve has a mounting portion to the washstand on the outer periphery of the upper part and a chamber in which a push rod is elastically installed inside, A primary water supply chamber is provided at the bottom of the chamber with a secondary water supply chamber separated, and
A plunger is attached to the threaded part of the push rod that penetrates the primary water supply chamber, and the packing part of the plunger opens and closes the valve seat opening, and the cleaning water introduced from the valve seat opening into the secondary water supply chamber is supplied to the Takotsumi piping. A plurality of nozzles are communicated through a pipe, a branch part, and a branch pipe, and a T-shaped water hole is provided in the plunger to communicate a pressure chamber provided between the plunger and the cover plate with the valve seat opening; By introducing a portion of the wash water during the water supply into the pressure chamber from the water hole, a brake-like control is applied to the speed of restoration in the valve closing direction due to the elastic load of the push rod, and during this time it flows out from the valve seat opening. Washing water is connected so that the amount necessary for washing the washbasin is discharged and the valve is automatically closed, and a hole is arranged at a high position in the middle of the water supply pipe to communicate with the outside air. By arranging a vacuum break valve mechanism that has an intake valve that opens the pores when the internal pressure is negative and introduces outside air to break the vacuum in the water supply pipe, it is possible to prevent water from suddenly cutting off while washing or washing hair, or to prevent the water from running out of the washbasin. The check valve is designed to prevent dirty water from the washbasin from flowing backwards through the nozzle, branch piping, water supply pipe, etc. due to the drain hole being clogged with hair or other foreign matter. It is linked to.

(Function) When the push button on the washbasin holder is pressed, the water supply valve opens, and the cleaning water flows through the horizontal water hole drilled perpendicularly to the nozzle tip of the Takoashi piping and the direct water hole opened in the axial direction. The water is sprayed out from the sink to thoroughly clean the entire inside of the washtub, and when the constant flow of washing water is finished, the valve seat opening is automatically closed, preventing water outages or clogged drain holes while washing or washing hair. If the sewage in the washbasin attempts to backflow from the nozzle part due to this, the backflow of sewage is prevented by operating a vacuum breaker mechanism between the nozzle part of the takozo piping and the water supply valve.

(Example) Examples of this invention are shown in Figures 1, 2, and 3.
As shown in FIG. A primary water supply chamber 2 is provided, and this primary water supply chamber 2 communicates with a water supply pipe 45 (described later) that communicates with a water supply source, and a secondary water supply chamber 3 communicates with the primary water supply chamber 2 via a valve seat opening 6, and which will be described later.

A gasket 13 is fitted into a groove 16 on the circumferential surface of the lower end, and a pressure spring 14 is interposed between the water hole 11 and a cover plate 17 for removing foreign matter clogging the water hole 11. At a high position between the water supply pipe 45a communicating with the secondary water supply chamber 3 and the water supply pipe 45b connected to the branch part 31 of the octopus piping C, which will be described later, there is a water supply pipe 45b connected to the branch part 31 of the octopus piping C, which will be described later. The vacuum breaker mechanism A is provided to break the vacuum in the water supply pipe 45a so as to prevent the drain hole 40 of the tank 39 from being clogged with hair or other foreign matter and the sewage in the wash tank 39 from flowing back. The vacuum breaker mechanism A has an elbow-shaped main body 18, and has an upstream water supply pipe 45a.
The check valve part 19 is provided with a check valve part 19 in the horizontal direction and an intake valve part 20 in the vertical direction. A spring 24 is interposed between the back surface of the check valve body 22 and a lid 25 screwed onto the main body 18, and the check valve body 22 is connected to the valve seat 21.
When water is supplied, the check valve body 22 contracts the spring 24 and detaches from the valve seat 21 due to the wash water flowing from the water supply valve 1 into the main body 18 while passing through the water supply pipe 45a and its water pressure. However, if there is a water outage or the drain is clogged, the cleaning water that tries to flow back from the water supply pipe 45b to the main body 18 will be blocked by a back check. Since the valve seat 21 is closed by the operation of the valve body 22, the water is arranged to prevent backflow to the upstream water supply pipe 45a. The intake valve section 20 is the main body 18

As shown in FIG. 1, the washstand B has an upper mirror cabinet 37, a lower washbasin holder 38, and a washbasin 39 approximately in the center of the washbasin holder 38.
A drainage hole 40 is provided at the bottom of the washbasin 39.
An overflow port 41 is formed in the upper part of the side surface, and the above-mentioned nozzle parts 35 are installed on the side surface of the inner wall of the washtub 39 at equal intervals on all sides, and the above-mentioned nozzle part 35 is installed around the washtub 39. A push button 7 of the water supply valve 1, a holder 43 for supporting a shower head 42 which can be freely drawn out, and a hot water mixer faucet 44 for adjusting the temperature and flow rate of mixed water supplied to the shower head 42 are attached.

Now, after washing your hair using the washstand B shown in FIG. When pressed by hand, the push rod 4 inside the water supply valve 1 shown in FIGS. 2 and 3A moves down (in the figures) against the elasticity of the spring 8. As the push rod 4 descends, the plunger 5 descends, so
The packing part 12 integrated with the plunger 5 is lowered to open the valve seat opening 6. Through this operation, cleaning water is supplied from the primary water supply chamber 2 to the secondary water supply chamber 3, and the water supply pipe 4 of the Takotsu piping C that communicates with the secondary water supply chamber 3

Since the water hole 36 and the direct water hole 36a are provided horizontally and vertically, respectively, with respect to the washbasin 39, the entire surface of the washbasin 39 can be evenly washed as shown in FIG. At the same time as the water is supplied to the above-mentioned octopus piping C, a part of the cleaning water is passed through the valve seat opening 6, the primary water supply chamber 2, and the water hole 11 of the plunger 5, as shown in FIGS. 2 and 3 A. In order to be introduced into the pressure chamber 10 under pressure, a brake-like control is applied to the speed at which the push rod 4 returns in the valve closing direction due to the elastic load. The amount of washing water necessary for washing the washbasin 39 for one time is released and the valve is automatically closed. Therefore, when the push button 7 is pressed once, a certain amount of washing water is jetted from the nozzle portion 35 into the wash basin 39.

Next, during hair washing, the drain hole 40 and the drain pipe downstream of the overflow port 41 become clogged with hair, lint, and other foreign matter, and dirty water overflows into the wash basin 39, causing the horizontal water hole of each nozzle part 35 to become clogged. 36 and the direct water hole 36a to the octopus piping C, the check valve body 22 of the vacuum breaker mechanism A shown in FIG. At the same time, the operation of the check valve body 22 causes the internal negative pressure of the water supply pipe 45a to operate the pore valve 28 of the intake valve section 20 and open the pore 27, so that outside air is introduced from the pore 27 and the water supply is prevented. The vacuum inside tube 45a is broken.

(Effects) This invention has the following advantages because it is configured as described above.

(1) The water supply valve that supplies cleaning water to multiple nozzles fixed to the inner wall of the washbasin forms a pressure chamber at the bottom of the plunger integrated in the push rod, and when the valve is opened, the cleaning water is sent to the Takotsu piping. At the same time as supplying water, part of it is forced into the pressure chamber through a water hole drilled in the plunger, so the plunger rises according to the volume of washing water that is forced into the pressure chamber with a single push button operation. Since the valve seat opening is gradually closed while controlling the speed, a constant amount of washing water can always be supplied to the washbasin to ensure washing.

(2) A vacuum breaker valve mechanism consisting of a check valve and an intake valve is installed in the water supply pipe between the water supply valve and the branch that connects to multiple nozzles, so if there is a sudden water outage or a foreign object causes the drain pipe to Even if sewage overflows into the washbasin due to a blockage, etc., and the sewage flows back into the octopus piping from the side water hole and direct water hole of the nozzle, the check valve prevents the sewage from entering and prevents the internal drain. Since outside air is introduced into the water supply pipe by the actuation of the intake valve section by pressure, the vacuum inside the water supply pipe can be broken and the backflow of sewage into the Takotsu piping can be prevented.

(3) The tip of the nozzle part fixed inside the washbasin is equipped with a water fountain that spouts cleaning water in the inner circumferential direction of the washbasin and a direct water hole that spouts downward, so that The entire surface can be thoroughly cleaned.
