Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toilet bowl cleaning tank device, and particularly to one in which the tank is equipped with a handwash pipe.

Conventionally, there is a toilet cleaning tank device of this type as shown in FIGS. 1 and 2 of Japanese Utility Model Application No. 54-58858.

To explain this, Ball Tap B
A distribution valve C is installed at the outflow portion 6 opened at the axial tip of the
This distribution valve C has a tank water supply port 12 and a hand wash water supply port 7 spaced apart from each other at a distance from a cylindrical distribution valve body C' whose opening at one end of the cylindrical body is closed with a blind lid. A piston-shaped distribution valve body 15 is provided so as to branch perpendicularly to the axial direction of C', and is slidably inside the main body C' and is biased by a spring 16 in the direction of closing the tank water supply port 12. In addition, the valve body 15 is provided with a water inlet 14 that communicates the primary side with the hand wash water inlet 7.

Therefore, this device changes the water flow area of each of the tank water supply port 12 and the handwash water supply port 7 on the outer peripheral surface of the distribution valve body 15 by sliding the valve body 15, thereby reducing the amount of water flowing out from the handwash pipe 1. Although the pressure is kept almost constant even if the pressure fluctuates, there is a drawback that limescale and dirt adhere to the sliding parts, resulting in malfunction and unstable flow from the handwash pipe 1.

Furthermore, the distribution valve is difficult to disassemble, making it difficult to carry out repairs and inspections in the above-mentioned cases.

In addition, in order to operate the distribution valve body 15 accurately, the dimensions of the inside diameter of the distribution valve body C' and the outside diameter of the distribution valve body 15 must be precisely machined, and this has the disadvantage that it is difficult to manufacture.

The present invention eliminates these drawbacks, prevents limescale and dirt from adhering to the valve part of the distribution valve, stabilizes the amount of water flowing out from the handwash pipe, and is easy to manufacture and repair and inspection. The purpose is to

The basic structure of the present invention is that the distribution valve has a first small diameter part on the upstream side and a first large diameter part on the downstream side through the first stage part, and the first small diameter part is the outflow part of the ball tap. A hand wash water supply port is formed in the first small diameter part, and the first tubular member forms a distribution valve seat in the first stage part, and the second large diameter part is connected upstream through the second stage part. , and a second tubular member having a second small-diameter portion on the downstream side and a lower end opening of the second small-diameter portion serving as a tank water supply port, and the distribution valve main body is formed of the first, The large diameter portions of the second tubular member are screwed together to form a distribution valve chamber, and the distribution valve chamber has an outer diameter slightly smaller than the diameter of the distribution valve chamber, and has a water passage in the axial direction approximately in the center. A distribution valve body with a perforation is provided, and the distribution valve body is always connected to the first stage by a spring placed on the second stage part.
It is biased toward the stepped portion, and is seated on the distribution valve seat when water is not flowing.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG. 4, a ball tap B provided on a toilet cleaning tank body A is of a type in which a main valve b is opened by a pilot valve a.

That is, when the water level of the ball tap B falls due to the float 2 that responds to the water level in the tank body A, the pilot valve a opens, and the pressure in the pressure chamber 17 provided behind the main valve b increases to the level on the primary side of the main valve b. When the pressure becomes smaller than the pressure, the main valve body 18 formed by a diaphragm moves toward the pressure chamber 17, and the main valve b opens, so that water flows from the inflow part 19 to the outflow part 6.

Incidentally, as the ball tap B, an ordinary ball tap B which is not a pilot type may of course be used.

On the other hand, the tank body A has an operation handle 20 at the bottom.
A drain valve 21 is provided which opens when the valve is operated, and a lid 22 is provided which communicates with the toilet bowl through the valve and has a gooseneck-shaped wash pipe 1 at the top.

The outlet 6 of the ball tap B has a distribution valve C.
will be established.

The distribution valve C has a first valve that interconnects the distribution valve body C'.
It is composed of a tubular member C-1 and a second tubular member C-2 and is connected to the outflow portion 6 of the ball tap B.

The first tubular member C-1 has a first small diameter part 4 on the upstream side and a first large diameter part 5 on the downstream side via a first stage part 3 provided in the middle part in the axial direction. A first male screw 23 is provided on the outer periphery of the portion 4, and a second male screw is provided on the outer periphery of the first large diameter portion 5.
A male screw 24 is provided respectively.

Further, the first tubular member C-1 has a first small diameter portion 4,
A hand wash water inlet 7 having a larger diameter than a water inlet 14 of a distribution valve body 15, which will be described later, is opened to protrude outward perpendicular to the axial direction of the first tubular member C-1, and is distributed to the first stage portion 3. A valve seat 8 is formed.

On the other hand, the second tubular member C-2 is connected to the second large diameter portion 1 on the upstream side via the second step portion 9 provided in the middle in the axial direction.
0, the downstream side is formed in the second small diameter part 11, and the second
A female screw 25 is provided on the inner periphery of the large diameter portion 10, and a second
The small diameter part 11 is extended long and the opening at the end is made into a tank water supply port 12.

The first tubular member C-1 and the second tubular member C-
2 is the former second male screw 24 and the latter female screw 25
are screwed together to form a distributing valve body C'.

This distribution valve body C' is connected to the first tubular member C-
Connect the first male screw 23 of 1 to the outflow part 6 of ball tap B.
By screwing into the female screw 26 for connecting the distribution valve provided on the inner periphery, it is connected to the ball tap outlet 6 and extends to near the bottom of the tank body A.
is a hand wash connecting pipe 27 with a flexible bellows part.
It is connected to the hand wash pipe 1 on the top surface of the tank body A through.

The distribution valve main body C' has a large diameter space formed by the first large diameter part 5 and the second large diameter part 10 between the first stage part 3 and the second stage part 9 as a distribution valve chamber. 13, and the distribution valve chamber 13 accommodates and arranges a distribution valve body 15 and a spring 16 that urges the distribution valve body 15 toward the distribution valve seat 8 side.

The distribution valve body 15 has a stepped circular seating surface 15a corresponding to the distribution valve seat 8 at its upper part, and above it is a tapered inclined part 28 whose base has the same diameter or slightly smaller diameter than the inner diameter of the distribution valve seat 8 hole. A cross-shaped leg portion 29 is provided at the bottom, a protrusion 30 having a diameter slightly smaller than the inner diameter of the distribution valve chamber 13 is provided at the upper end of the leg portion 29, and a water inlet 14 is provided in the center portion to penetrate in the vertical axial direction. do. (See FIGS. 7 and 8) The distribution valve body 15 is slidably disposed in the distribution valve chamber 13.

The spring 16 is elastically mounted between the second stage portion 9 of the distribution valve body C′ and the protrusion 30 of the distribution valve body 15.
is always urged toward the distribution valve seat 8, and the distribution valve body 15 is seated on the distribution valve seat 8 when water is not flowing.

In the figure, reference numeral 31 denotes a pressure reducing member installed upstream of the main valve b, which houses a plurality of pressure reducing plates 33 with a large number of small holes drilled in the liner 32, and the pressure reducing member 31 has a water flow area. By reducing the size, the force of the water flow is temporarily weakened and the sound of running water is reduced.

Therefore, in such a toilet cleaning tank device, the main valve b of the ball tap B is opened, and the water in the inflow part 19 flows to the outflow part 6.
When it flows into the distribution valve main body C', a part of it is discharged from the handwash pipe 1 through the handwash water supply port 7, the handwash communication pipe 27, and the other part is discharged from the handwash pipe 1 through the water supply port 14 of the distribution valve body 15.
It is then discharged into the tank body A from the tank water supply port 12.

At this time, if the water pressure at the installation location is high,
The water presses the distribution valve body 15 downward, the spring 16 contracts, and the distribution valve body 15 has its protrusion 30 on the inner peripheral surface of the distribution valve chamber 13 and the legs 29 on the inner peripheral wall of the second small diameter portion 11. As they are guided and moved downward, the distribution valve body 15 is slightly separated from the distribution valve seat 8 and the water inlet 14 is moved downward.
Apart from the water flowing through the distribution valve seat 8, water also flows into the gap between the inner periphery of the distribution valve seat 8 hole and the inclined portion 28 of the distribution valve body 15, the gap between the distribution valve seat 8 and the seating surface 15a, and the gap between the leg portion 29 of the distribution valve body 15 and the distribution valve. It flows between the inner wall of the chamber 13 and the tank water supply port 1.
Sent to 2.

Therefore, the distribution valve C opens and closes in response to the level of water pressure, and when the water pressure increases, the opening degree of the distribution valve C increases and the amount of water sent to the tank water supply port 12 increases.
The flow rate of water discharged from the hand washing pipe 1 is kept almost constant.

In this embodiment, the tank water supply port 7 of the distribution valve C is opened near the bottom of the tank body A, that is, below the surface of the stored water, so that water is discharged directly into the stored water. It is possible to prevent the generation of noise caused by the water discharged from 12 hitting the surface of the stored water.

Next, FIGS. 9 and 10 show other embodiments of the first tubular member constituting the distribution valve body. It has an auxiliary water supply port 34 opened orthogonally to the hand wash water supply port 7, and the auxiliary water supply port 34 is
It communicates via an auxiliary water communication pipe 36 with an overflow pipe 35 provided in the tank body A and communicating with the toilet bowl.

Therefore, this product can supply a portion of the water from the auxiliary water supply port 34 to the toilet bowl through the auxiliary water communication pipe 36 and the overflow pipe 35, and can be used as a water seal for the trap part of the siphon type toilet bowl.

Moreover, what is shown in FIG. 11 is the second tubular member C.
-2 shows another embodiment of tank water supply port 1.
The control member 38 is a combination of a plurality of nets 37 or a rectifying plate formed by bending a thin narrow band plate in a corrugated manner to form a planar star shape or chrysanthemum shape. It was installed. Therefore, in this case, the direction of the water flow is adjusted by the control member 38, and the water flow is expanded to slow down the flow velocity, and the flow is discharged from the tank water supply port 12 in a quiet laminar flow state similar to flowing starch syrup. Even if the tank water supply port 12 is located above the reservoir water surface, the sound of discharged water hitting the reservoir water surface can be prevented from occurring.

In addition, if a pilot type ball tap is used as described above, if the drain valve does not completely shut off water and leaks a small amount of water, even if the ball tap opens due to a drop in the water level, most of the water will still drain out. It flows out from the tank spout through the water passage, which has the effect of preventing accidental outflow from the handwash pipe.

Since the present invention has the above configuration, it has the following advantages.

The valve part of the distribution valve is structured so that the valve body approaches and separates from the valve seat, so limescale and dirt do not adhere to the valve part, the distribution valve always operates accurately, there is no malfunction, and there is no pressure fluctuation. Regardless of the situation, a stable and constant flow of water can always be discharged from the handwash pipe.

Compared to conventional valves, the dimensions of the outer diameter of the valve body and the inner diameter of the main body of the distribution valve do not have to be exact.
It is easy to manufacture, and I have never experienced poor performance.

Compared to conventional models, it is compact with fewer branching parts from the distribution valve body, and the distribution valve does not interfere with the operation of the ball tap or drain valve within the tank body.

The distribution valve main body is composed of a first tubular member and a second tubular member that are screwed together, and can be easily disassembled and removed, making it easy to repair and inspect the distribution valve.
