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.

On the other hand, in order to simplify installation and the like, the vacuum breaker may be integrated into the vanity. However, since the vacuum breaker is an open valve type,
Since the water supply may overflow, it is necessary to provide an overflow route.

Further, when the vacuum breaker is housed inside a makeup mirror on a washbasin and the overflow pipe is directly connected to the drain pipe, overflow cannot be known from the outside.
Therefore, the valve body of the vacuum breaker is drained while the valve body is open, and the water is wasted.

Therefore, an object of the present invention is to make it possible to collect an overflow from a vacuum breaker.

[Means for solving the problem]

The present invention is a sanitary facility having a ball for washing or washing hair and a water supply system for the ball, and the ball has a water passage for washing the ball, which is a level higher than the maximum water collecting surface of the ball. The water supply system is provided with a water supply passage to the water passage that passes through, and a vacuum breaker having a valve mechanism for opening to the atmosphere when the pressure in the passage of the supply passage becomes negative pressure is incorporated in the water supply system. Further, an overflow pipe is connected to the vacuum breaker, and the overflow pipe is used as a water recovery path toward the ball.

[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 overflow pipe connected to the vacuum breaker collects overflow water generated by dust clogging of the valve body of the vacuum breaker, and the collection destination is a ball.
Therefore, the overflow water flows down from the overflow pipe to the ball, and the overflow of the vacuum breaker can be collected.

4 to 7, the washbasin 1 is fixed on the cabinet 2, and the makeup mirror main body 3 is started up in series with the back guard 1a on the back of the washbasin 1, and the makeup mirror main body 3 is raised.
It is fixed to. 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 8 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.

The vacuum breaker 12 is connected to the upper end of the rising pipe 11a at the back of the back guard 1a, and its details 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. 2 (b), the cap 12d has a mounting seat 12f of a spruddle 12e spanned in the radial direction and an opening 12g is formed below the mounting seat 12f. In the state of FIG. The portion 12g is opened 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 that covers the cap 12d, guides water overflowing from the opening 12g to the tray 13, and prevents dust from entering the main body 12a.

Supply pipe to be piped between the main body 12a and the water passage 10a of the rim 10.
As shown in FIGS. 4 and 5, the reference numeral 15 is connected to two connection ports 10c opened on 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.

The makeup mirror body 3 is formed of a thin synthetic resin sheet, and as shown in FIG. 7, a shelf 3b is formed under the mirror 3a, and a recessed storage portion 3c is provided under the shelf 3b. ing. The bottom wall 3d of the storage 3c is the washbasin 1 as shown in FIG.
It is placed on the back guard 1a. Storage
The left and right ends of 3c are partitioned by the sheet of the makeup mirror body 3 as shown in FIG. 10, and a cavity 3e is formed on the back side. Then, using the space of this cavity 3e, the start-up pipe
11a part, vacuum breaker 12, overflow pipe 14
And a part of the supply pipe 15 is housed. Therefore, when the makeup mirror main body 3 is integrated with the basin 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.

Further, in order to collect the water from the overflow pipe 14 to the basin 1 side, a drain 16 is connected to the lower end of the overflow pipe 14 as shown in FIGS. 1 and 2, and the overflow water is discharged to the basin 1. The drain 16 is formed in an L shape as shown in FIG. 3, has a discharge port 16a having a wide front direction, and has a double-sided adhesive tape 16 on the lower surface for fixing to the back guard 1a.
b is pasted. On the other hand, a mounting seat 1a-1 for the drain 16 is provided as a recess on the upper surface of the back guard 1a.
It is fixed to -1 as shown in FIGS. Further, as shown in FIG. 1, a baffle plate 3f is provided 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. This water supply pressure causes the valve body 12c to move upward in FIG. 9 (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, It is discharged to the washbasin 1 through the water 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.

Here, if the valve body 12c of the vacuum breaker 12 is left open due to bite of dust or the like, water overflows to the tray 13 when water is supplied. This overflow water naturally falls from the overflow pipe 14 to the drain 16 and the discharge port 16
It is discharged to the washbasin 1 from a. Therefore, even if an overflow occurs in the vacuum breaker 12, all the water is collected in the washbasin 1 without falling outside or in the cabinet 2.

In this way, the vacuum breaker 12 is installed in the back side of the washbasin 1 at a higher level than this and the overflow breaker is directly installed.
Since 14 is directed to the washbasin 1 side, there is no need to connect it to the building pipes, which simplifies construction. Further, since the drain 16 faces the washbasin 1, when an overflow occurs, it can be visually confirmed, and the abnormality of the vacuum breaker 12 can be easily known. Therefore, the makeup mirror body 3
Even if the vacuum breaker 12 is housed inside, it is possible to confirm failures etc. from the outside.

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.

[Effect of device]

The present invention connects a supply path for ball cleaning to a water supply system such as a faucet provided for a ball on a vanity or a hair wash table, and allows the supply path to pass a level higher than the overflow surface of the ball. A vacuum breaker is assembled, and an overflow pipe connected to this vacuum breaker collects overflow water in a bowl such as a washbasin. Therefore, compared to the case where the overflow pipe is connected to the building's pipe, the piping is simpler and the equipment can be installed in units such as a vanity and a hair wash stand, and it is the same as equipment that does not have a ball washing function. Can be easily installed on. Further, since the overflow water flows into the bowl of the washbasin or the like, this can be visually confirmed, and even if the assembly structure is such that the vacuum breaker is hidden, the failure thereof can be known.
