Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sanitary facility which is used in a wash basin or a shampoo table and has a ball washing function.

[Conventional technology]

A wash basin, a hair wash basin, and the like generally have a structure in which auxiliary balls are provided around a ball that receives water. For example, the ball is fixed on a cabinet installed on the floor, or in the case of a vanity stand, the ball is used as a washbasin and a makeup mirror is attached.

Some recent vanities include a hand shower as well as a face washer that can wash hair, and are widely used for home use. In a vanity table having such a function, facilities have been expanded such as incorporating an electric water heater or the like in a cabinet to use hot water. And the most important thing as a sanitary facility is to keep the area around the facility clean, and one example thereof is one that has a function of cleaning balls.

In ball cleaning, a flow path is formed around the rim of the ball, and water is discharged toward the ball surface from a number of holes formed in the flow path. By adopting such a ball cleaning, even in equipment used by many people, the inside of the ball can be cleaned and used comfortably.

[Problems to be solved by the device]

A water supply pipe connected to the rim of the ball for supplying water for ball washing needs a mechanism for preventing a backflow due to the generation of a negative pressure in the pipe. This is because the water between the discharge end and the closed valve is gradually discharged after the water supply is stopped in the flow of the pipe, and the inside of the pipe becomes a negative pressure, so the purpose is to prevent the backflow of water from the discharge end. It was done. A vacuum breaker is generally used to prevent negative pressure in a pipeline. This is provided with a valve for opening to the atmosphere, and when the pressure in the pipeline becomes negative, this valve is opened and air is sucked into the inside to release the negative pressure.

However, in the past, this vacuum breaker had no other option than to be installed in the piping of the building. One reason for this is that the vacuum breaker needs to be installed at a position that is somewhat higher than the highest level of the water surface of the ball as an installation condition.

Further, in order to simplify the installation and the like, the vacuum breaker may be integrated into the vanity. However, since the level of the vacuum breaker must be set above the washbasin, the vacuum breaker will come out on the front side or side of the makeup mirror, side cabinet, etc. Therefore, the vacuum breaker and its piping are exposed from the cabinet of the vanity, the washbasin, and the like, which is not preferable in terms of appearance, and when it sticks out to the side, it does not match the installation frontage.

Therefore, in the present invention, the vacuum breaker is stored using the space inside the body of the makeup mirror, and piping and installation can be performed as easily as a normal hair wash vanity, and there is no problem in appearance. The purpose is to do so.

[Means for solving the problem]

The present invention is a sanitary device including a ball for washing or washing hair and a water supply system for the ball, a water passage for washing the ball is provided in the ball, and a storage box such as a makeup mirror is arranged above the ball. The facility is provided with a water supply passage to the water passage that passes through a level above the maximum reservoir surface of the ball, in the water supply system, and the supply passage has a negative pressure in the passage. It is characterized in that a vacuum breaker having a valve mechanism for opening to the atmosphere is incorporated, and the vacuum breaker is housed inside the main body of the housing box together with its piping system.

[Action]

When water is fed into the rim water passage from the ball cleaning water supply channel provided in the ball water supply system, water flows out from the discharge end of the rim into the ball surface, and the ball surface is discharged. Washed. When the supply of water is stopped, the supply end side closes and water continues to be discharged to the discharge end, so that the pressure in the supply path is reduced. At this time, the valve of the vacuum breaker arranged at a level higher than the water level of the ball stops the flow of water and opens the opening to the atmosphere to open the inside of the supply passage to the atmosphere. For this reason, the air is sucked into the supply path, the negative pressure is eliminated, and the backflow of water is prevented.

The vacuum breaker and its piping are housed inside the main body of a storage box such as a makeup mirror arranged above the ball, and do not stick out or be exposed to the outside. Since the vacuum breaker is included in the water supply system for the balls, it can be assembled in units of equipment as in the case of piping for faucets and the like. For this reason, it is not necessary to newly install a vacuum breaker in the building piping, and installation of a cabinet such as a vanity or a hair wash table can be easily performed as in the case of the equipment having no ball cleaning function.

〔Example〕

Hereinafter, the features of the present invention will be described using the vanity stand shown in the drawings as an example.

FIG. 1 is a cutaway front view showing the essential parts of the vanity together with the internal structure, FIG. 2 is a plan view of only the washbasin (ball), FIG. 3 is a partial cutaway side view of the essential parts, and FIG. 4 is It is a perspective view of the whole bathroom vanity.

In the figure, a washbasin 1 is fixed on a cabinet 2, a makeup mirror main body 3 is started up in a row with a back guard 1a on the back of the washbasin 1, and is fixed to the cabinet 2. A drain pipe 1b is connected to the bottom of the washbasin 1, and a hot and cold water mixing tap 4, a spout 5 and a hand shower 6 each having an automatic temperature control function are arranged on the back side.

Figure 5 is an outline of the water and hot water supply system, cabinet 2
Pipe lines are formed from the water supply pipe 7 and the hot water supply pipe 8 which are piped inside to the respective discharge ends, and a solenoid valve box 9 is further incorporated. Pipe lines 7a and 8a connected to the water supply pipe 7 and the hot water supply pipe 8 are connected to the hot and cold water mixing valve 4, respectively, and the outlet side of the hot and cold water mixing valve 4 and the solenoid valve box 9 are connected to each other by the gas channel 4a. Then, a flow path from the spout solenoid valve 9a of the solenoid valve box 9 to the spout 5 is formed by the conduit 5a. The solenoid valve box 9 has a shower solenoid valve 9b.
Is provided, and the hose 6a connected thereto is connected to the hand shower 6.

With such a flow path structure, hot water or water whose temperature is adjusted by the temperature adjusting handle 4b of the hot and cold water mixing valve 4 is sent to the solenoid valve box 9. Then, when the spout solenoid valve 9a is opened, water is discharged from the spout 5, and its flow rate is adjusted by a flow rate adjusting handle 5b provided on the spout 5. On the other hand, when the shower solenoid valve 9b is opened, the hose 6a pulls the hand shower 6
Is supplied with water or hot water.

In order to wash the ball, the basin 1 forms a water passage 10a around the entire circumference of the rim 10 and a large number of water injection holes 1a toward the ball.
0b is open. In addition to forming the water passage 10a integrally with the basin 1, a washing pipe may be provided along the upper edge of the ball, and a large number of water holes may be formed in the washing pipe. On the other hand, a ball washing electromagnetic valve 9c of the electromagnetic valve box 9 is connected to another pipe 7b of the water supply pipe 7, and further connected to a water passage 10a of the rim 10 by a pipe 11. The pipe line 11 is provided with a vacuum breaker 12 for preventing backflow of water from the washbasin 1 to the pipe line 11 side.

The solenoid valves 9a, 9b, 9c for spouting, showering, and ball cleaning are operated by an operation panel 9d provided at the upper end of the washbasin 1. In this case, it is preferable that the solenoid valves 9a to 9c be opened one by one, or the controls be arranged so that operations such as opening the spout and the shower at the same time can be performed.

The vacuum breaker 12 is connected to the upper end of the rising pipe 11a at the back of the back guard 1a, and details thereof are shown in FIG. A rising pipe 11a and a supply pipe (described later) to the water passage 10a of the rim 10 are connected to a lower end of the main body 12a of the vacuum breaker 12. A valve seat 12b is formed at an upper end of a portion where the riser pipe 11a is inserted, and a valve body 12 that opens and closes the valve seat 12b.
c is built in. The valve body 12c is slidably attached to a spindle 12e of a cap 12d integrated with the upper end of the main body 12a. As shown in the plan view of FIG. 2B, the cap 12d has a mounting portion 12f of the spindle 12e spanned in the radial direction and an opening 12g below the cap 12d. In the state of FIG. The section 12g is open to open the supply pipe to the water passage 10a to the atmosphere. A packing 12h is attached to the upper end of the valve body 12c so as to be in close contact with the lower end surface of the cap 12d. Further, an overflow tray 13 is fixed to the upper end of the main body 12a, and an overflow pipe 14 is connected to this. Reference numeral 13a is a cover for covering the cap 12d and guiding the water overflowing from the opening 12g to the tray 13.

Supply pipe to be piped between the main body 12a and the water passage 10a of the rim 10.
As shown in FIG. 1 and FIG. 2, 15 is connected to two connection ports 10c opened in the innermost back wall of the rim 10. Therefore, the water supplied via the vacuum breaker 12
It flows into the water passage 10a by the supply pipe 15, and is discharged as shown by the arrow in FIG. 5 from the water spray hole 10b opened toward the ball surface, so that the ball portion of the washbasin 1 can be washed.

Here, since the vacuum breaker 12 has a structure that cannot be seen from the outside, it is hidden in the makeup mirror body 3 by including it. The makeup mirror body 3 is formed of a thin synthetic resin sheet, and as shown in FIG. 4, a shelf 3b is formed below the mirror 3a, and a recessed recess 3c is provided below the shelf 3b. ing. The bottom wall portion 3d of the storage portion 3c is placed on the back guard 1a of the washbasin 1 as shown in FIG.

As shown in FIG. 7, the left and right ends of the storage portion 3c are the main body 3 of the makeup mirror.
And a cavity 3e is formed on the back side. Then, a part of the rising pipe 11a, a vacuum breaker 12, an overflow pipe 14, and a part of the supply pipe 15 are accommodated in the space of the hollow portion 3e. Therefore,
When the makeup mirror body 3 is integrated with the washbasin 1, the vacuum breaker 12 is assembled so that it cannot be seen from the outside.

Since the vacuum breaker 12 can be hidden in the makeup mirror body 3 in this manner, the vacuum breaker 12 can be set to a higher level than the washbasin 1. Therefore, the level that can function as a vacuum break valve is 150 mm from the highest water surface of balls.
Although it is set to a certain degree or more, the arrangement satisfying this condition becomes possible by arranging it above the back guard 1a.

Furthermore, in order to collect the water from the overflow pipe 14 to the basin 1 side, the drain is attached to the lower end of the overflow pipe 14.
Connect 16 and drain the basin 1 to overflow. Drain 16 is the first
As shown in FIG. 10, an L-shaped discharge port 16a having a wide frontal direction is provided, and a double-sided adhesive tape 16b for fixing to the back guard 1a is attached to the lower surface.
On the other hand, on the top surface of the back guard 1a, the drain 16 mounting seat 1a-
1 is provided as a recess, and the mounting seat 1a-1 is shown in FIGS.
It is fixed as shown. As shown in FIG. 8, it is preferable to provide a baffle plate 3f so that the discharge port 16a cannot be seen from the front.

In the above configuration, when the ball cleaning solenoid valve 9c is opened, water is supplied to the vacuum breaker 12 from the conduit 11 and the rising pipe 11a. Due to this water supply pressure, the valve element 12c moves upward in FIG. 6 (a) to open the valve seat 12b, and water is sent from the supply pipe 15 to the water passage 10a of the rim 10 through the main body 12a. The water is discharged into the basin 1 through the spray hole 10b. When the ball cleaning electromagnetic valve 9c is closed, the supply of water is stopped and the water supply pressure is reduced, and the valve element 12c is lowered to close the valve seat 12b, and at the same time, the packing 12h opens the opening 12g of the cap 12d. As a result, the flow path on the side of the conduit 11 is closed and the supply pipe
The air is sucked together with the movement of the flow to the flow path 15, so that the flow in the pipe is prevented from becoming negative pressure, and the backflow to the upstream side is suppressed.

The vacuum breaker 12 is housed in the cavity 3e of the makeup mirror body 3 as shown in FIGS. 7 and 8, and the start-up pipe 11a.
The supply pipe 15 and the like are also located at the back of the washbasin 1. For this reason, the vacuum breaker 12 and the piping system thereof are all hidden, and the assembly can be performed without protruding to the side portion of the makeup mirror body 3. Therefore, attach the vacuum breaker 12 to the washbasin 1
The vacuum breaker 12 is included in the water supply system for spouts such as the spout 5, so there is no need to install the vacuum breaker 12 in the piping of the building as in the past. .

Although the bathroom vanity is described in the embodiment, it is needless to say that the present invention can be applied to a sanitary facility including various balls such as a hair washer. In addition to the makeup mirror, a makeup rack or the like that does not include a mirror may be used.

[Effects of the Invention] The present invention connects a supply path for ball cleaning to a water supply system such as a water faucet provided on a ball of a vanity table or a hair wash table, and the supply path passes a level higher than the reservoir surface of the ball. In this way, a vacuum breaker is assembled to this, and the vacuum breaker is housed inside the main body of a storage box such as a makeup mirror arranged above the balls. Therefore, the vacuum breaker can be provided integrally with the equipment, and it is not necessary to incorporate the vacuum breaker into the piping of the building as in the conventional case.
Therefore, the equipment can be installed in units of equipment such as a vanity and a hair wash table, and can be easily installed like equipment without a ball washing function. Also, since the vacuum breaker is not exposed to the outside, there is no problem in appearance, and since it is not tampered with, it can be used for public use. Further, by arranging the vacuum breaker inside, the leakage of air suction noise when the flow path is opened to the atmosphere is reduced, which is also suitable for household use.
