Regarding equipment.

[Conventional technology]

Conventionally, Utility Model Application No. 56-101263 was developed as a one-piece type toilet cleaning device in which the toilet body and the flushing water tank were integrally molded.
There is something described in the No.

This includes a ball tap, flow rate adjustment valve, and
A switching valve is arranged, and the flow path of this switching valve is switched from the inside of the flush water tank to the rim water passage direction by operating a handle provided on the outside, opening the flow path to the bowl part of the toilet bowl and It is equipped with a drain valve that closes when the water level in the tank falls and connects the flow path of the switching valve so that the inside of the tank opens.

In such a cleaning device, by operating the handle, the flow path of the switching valve is opened to the rim water passage side, and the drain valve is also opened to supply cleaning water to the ball part and the rim water passage side, and as the water level drops, the drain valve is closed. Closes, and in conjunction with this, the switching valve operates to open the flow path to the inside of the tank, and water is supplied from the ball tap until the water level in the tank becomes constant.

When the 1 liter water valve closes, the water supply to the toilet bowl stops, so it is necessary to supplement the amount of water sealed in the trap, and for this reason, the flow path in the direction of the rim water passage of the switching valve is always kept slightly open. A side road is formed so that Therefore, water is continuously supplied from this side passage to the rim passageway until the water supply to the ball tap is completely stopped, and water flowing down from the switching valve through the rim passageway ensures water sealing of the ball part. It has become.

[Problem that the invention seeks to solve]

By the way, in cold regions, etc., it is necessary to prevent condensation on the toilet bowl, and for this reason, in dew-proof flush toilets, heat insulating materials such as styrofoam are pasted inside the flush water tank and on the flow channel walls of the toilet body. is commonly practiced.

However, since the rim passageway of the toilet main body has a relatively narrow passage cross section, it is structurally impossible to provide such a heat insulating material.

Therefore, in order to keep the amount of water sealed in the trap to a predetermined value, if the cleaning water is configured to flow in the rim passageway until the ball tap operation is completed as in the past, the rim will be cooled during water supply. , there is a problem of dew condensation on the surface.

An object of the present invention is to provide a toilet bowl having a structure in which the toilet bowl body and the flush water tank are integrally molded, and to supply flush water from the flush water tank to the toilet bowl as a seal water directly to the toilet bowl without passing through the rim water passage from the flush water tank. By supplying the water to the bowl, the purpose is to prevent condensation on the toilet rim.

[Means for solving problems]

The present invention provides a wash water passage between a water sealing part of a toilet bowl portion and a wash water tank formed integrally with the toilet main body, and a ball tap in the wash water tank that communicates with an external water supply source; A switching valve that communicates with the ball tap and supplies water to either the wash water tank or the rim water passage of the toilet body, and a drainage valve that opens and closes the flow path between the tank and the wash water passage when the switching valve operates. The switching valve is further provided with an auxiliary flow path that communicates with the washing water passage when the rim water passage is closed.

〔Example〕

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a partially cutaway front view of a washing water tank according to the present invention;
FIG. 2 is a side view of the same, and FIG. 3 is a plan view of the same.

A is a flush water tank that is integrally formed in the toilet body B.
A ball tap C and a drain valve are arranged inside, and by opening and closing the drain valve, wash water is supplied from the wash water tank A to the ball portion E of the toilet body B. Furthermore, F is a flow rate adjustment valve connected to the ball tap C, and G is this flow rate adjustment valve F.
This is a switching valve for selectively supplying wash water to the inside of the wash water tank A and the rim water passage H formed at the top of the toilet body B.

The ball tap C is equipped with a valve body 2 in a main body l that communicates with an external water supply source, and this valve body 2 has a float 3 that rises and falls according to the water level.
The valve element 2 is connected to the valve body 2 via a lever 4, and the vertical swinging of the lever 4 causes the valve body 2 to approach and separate from the valve seat 2a to open and close the flow path.

The flow rate regulating valve F has a piston valve 5 having an inflow opening 6, which is slidably disposed and biased downward by a spring 7. In this flow rate adjustment valve F, water from the ball tap C flows into the piston valve 5 from the inflow opening 6, and the piston valve 5 moves up and down due to the water supply pressure at the time of inflow, changing the flow path area and flowing into the switching valve G. water supply flow rate can be maintained at a constant value.

That is, when the water supply pressure is large, the piston valve 5 rises due to the water supply pressure, and the taper part 8 formed on the circumferential surface of the piston valve 5 narrows the flow path area to the inflow opening 6, reducing the flow rate, and conversely, the water supply pressure increases. When the water pressure becomes low, the piston valve 5 is activated by the spring 7.
By descending and expanding the flow path around the tapered portion 8 to increase the flow rate, a constant amount of water can always be supplied to the switching valve G even when the water supply pressure fluctuates.

FIG. 4 is a cross-sectional view of the switching valve G, and FIGS. 5 and 6 are cross-sectional views taken along the line 1-1 and the line ■-■ in FIG.

The main body 9 of the switching valve G has an inlet 10 that communicates with the flow rate adjustment valve F, a first outlet 11 that communicates with the rim water passage H of the toilet body B, a second outlet 12 that communicates with the flush water tank A, and a second outlet 11 that communicates with the rim water passage H of the toilet body B. It has an auxiliary outflow port 13 that opens near the outflow port 12, and a valve chamber 14 with a circular longitudinal section is formed at a position substantially directly above the first outflow port 11.
A valve body 15 is rotatably built in to selectively open and close the flow passage between the side and the second outlet 12 and auxiliary outlet 13 side.

As shown in FIG. 5, the valve body 15 has a blocking part 17 between it and a pair of rotatable disc parts 16 within the valve chamber 14, which can block the flow paths to the respective outlet ports 11 to 13. The lid 1 is formed so that its peripheral surface is arcuate and is screwed onto the valve chamber 14 from the outside.
An exemplary disc part 16 is provided with a cylindrical part 19 through which the valve chamber 8 is inserted, and a protruding shaft 20 that fits into the side wall of the valve chamber 14 is provided in the disc part 16 on the other side.

An actuation lever 21 is fixed to the cylindrical portion 19, and a balance weight 22 is integrally formed on this actuation lever 21.
The drain valve body 2 of the drain valve is pivotally connected to the overpuff pipe 26 via the chain 23.
A groove 25 is formed at the opening of the first outlet 11 of the valve chamber 14 to connect the valve chambers I4 and bulges downward from the wall surface of the valve chamber I4. Since the switching valve G is a sliding valve, this groove 25 is provided to reduce the frictional resistance when the valve body 15 rotates.

Further, 30 is a rim supply pipe that is connected to the first outlet 11 and has a relief joint 31 in the middle and connects to the rim water passage H; 32 is connected to the second outlet 12 and has its lower end inside the wash water tank A. 33 is an auxiliary supply pipe connected to the auxiliary outlet 13.

The auxiliary supply pipe 33 is made of a flexible rubber pipe or the like and is piped upright into the cleaning water tank A using a clip 34.
Cleaning water passage formed between the lower part and toilet body B! It is connected to a discharge pipe 35 that communicates with.

This flushing water passage I communicates with the bowl part of the toilet body B,
During cleaning, the drain valve is opened and cleaning water flows directly from the cleaning water tank A, and water is also supplied from the auxiliary flow path W formed by the auxiliary outlet 13, the auxiliary supply pipe 33, and the discharge pipe 35. , the ball portion E can be sealed with water.

The relief joint 31 disposed on the rim supply pipe 30 forms a T-shaped flow passage cross section, and has a branch pipe 36 extending downward from the main flow passage.

Further, reference numeral 40 denotes an operating handle disposed outside of the wash water tank A, and an operating rod 42 is attached to the cylinder 41 so as to be pivotable in the vertical direction. This operating loft 42 engages with the operating lever 21 to rotate the valve body 15.

In the above configuration, under normal conditions, the operating lever 21 is tilted downward by the balance weight 22 as shown in FIG. 1, and at this time, the valve body 15 is in the position shown in FIG. Only the flow paths on the second outlet 12 and auxiliary outlet 13 sides are open.

When the operating handle 40 is pushed down, the operating lever 21 is rotated upward by the operating rod 42, and the drain valve body 24 connected to the operating lever 21 via the chain 23 is pulled upward. The drain valve opens. This allows the cleaning water in the cleaning water tank A to flow through the cleaning water path! The waste flows into the toilet bowl body B and is supplied to the pole portion of the toilet bowl body B, where the waste is discharged.

At the same time, the valve body 15 of the switching valve G rotates as shown in FIG.
Then, the auxiliary outlet 13 side is closed, and the flow path is switched.

In addition, as the water level drops due to the discharge of self-cleaning water from tank (A), the float 3 also descends, and the valve body 2 separates from its valve seat to open the valve and start supplying cleansing water into the cleansing water tank A. .

By opening the flow path of the ball tap C, the cleaning water flows from the first outlet 11 of the switching valve G through the rim supply pipe 30 into the rim water passage H. The inflowing washing water is discharged from a plurality of injection ports 37 provided in the rim passageway H along the side wall of the ball portion E while washing.

On the other hand, when the push-down force on the operating handle 40 is released, the engagement between the operating lever 21 and the operating loft 42 is disengaged, and the operating lever 21 becomes free, causing the washing water in the washing water tank A to drain to the drain valve. When water flows out from the drain valve, the drain valve body 24 seats on its valve seat and closes the valve.

When the drain valve body 24 is closed, the operating lever 21 rotates via the chain 23 to close the first outlet 11 and open the flow path on the second outlet 12 and auxiliary outlet 13 sides. Therefore, the cleaning water from the ball tap C is discharged into the cleaning water tank A through the second outlet 12 and the tank supply pipe 32, and is discharged from the auxiliary outlet 13 through the auxiliary supply pipe 33. Each flows down in the direction of the pipe 35.

As the water level rises as the wash water flows into the tank A, the float 3 also floats, and the valve body 2 of the ball tap C begins to move toward its valve seat, and the water supply flow rate gradually decreases until the valve closes completely.

When the ball tap C is closed, the auxiliary outlet 13
Since water is simultaneously supplied from the auxiliary supply pipe 33 to the flushing water passage (2), sealing water that functions as a trap can be replenished from the auxiliary supply pipe 33 to the ball portion E of the toilet main body B.

Cleaning water is not supplied to the rim water passage H until the operation of the ball tap C is completed.
Therefore, condensation on the rim can be reliably prevented.

Since the rim supply pipe 30 is provided with a branch pipe 36, when the water force flowing down from the switching valve G is strong, air is sucked from the open end of the branch pipe 36 by the flow rate of the cleaning water. Therefore, the cleaning water directly flows into the rim passageway H. On the other hand, if the water force is weak and the flow velocity is low, the cleaning water cannot rise completely and is discharged to the outside from the opening of the branch pipe 36 and flows into the rim water passage H.
Also, 38 is a heat insulating material placed on the inner surface of the wash water tank.

In this way, by providing the branch pipe 36 in the rim supply pipe 30, only the cleaning water with a high flow rate flows into the rim passageway H for a short time, so that it flows quickly in the rim passageway H and is sprayed. It can be discharged from the outlet 37, and condensation on the rim can be prevented in the same way as above.

Furthermore, in this embodiment, the auxiliary supply pipe 33 is connected to the cleaning water tank A.
Although the configuration is such that the water is connected to the discharge pipe 35 erected inside, it may be connected to the overflow pipe 26 and supplied to the wash water road (2).

〔Effect of the invention〕

The present invention uses an auxiliary flow path to supply water from the flush water tank to the toilet bowl as a water seal, without using the rim passageway as a route. The flushing water does not stay in the rim passageway (it has the effect of reliably preventing dew condensation on the toilet rim).
