Description

[Detailed Description of the Invention] The present invention relates to a water supply device that is used in a so-called bi-tank automatic toilet flushing device that intermittently and automatically flushes a toilet bowl using an automatic siphon, and that supplies water to a water tank equipped with an automatic siphon.

As shown in FIG. 7, the conventional bi-tank type automatic toilet flushing device is equipped with an automatic siphon 2 inside a water tank 1, and an outlet 3 of the automatic siphon 2 is connected to several urinals 5 via hot water pipes 4. In addition, a water tap 6 connected to a water pipe is provided above the water tank 1, and water is supplied from the water tap 6 to the water tank 1, and flushing water is intermittently sent to the toilet bowl 5 by the operation of the automatic siphon 2 to clean the toilet bowl. When the toilet bowl is not used for a long period of time such as at night, that is, when the toilet bowl does not need to be flushed for a long period of time, the water supply can be stopped by operating the water stop valve 7 installed on the building wall 35. It has become.

However, in places where a large number of toilets are installed in separate locations, such as in buildings, it is necessary to close the water stop valves installed on each device in several places, which is a difficult task. Because it is time-consuming and there is a lack of manpower, shut-off valves tend to be left unoperated, and even if they are not left unattended, they are sometimes forgotten to close, so they are regularly turned off even when the toilet is not being used, such as at night. Currently, water is often wasted by flushing toilet bowls.

On the other hand, as a solution to this problem, a patent application filed in 1973
-80534 (Japanese Unexamined Patent Publication No. 51-8747).

However, even though the solenoid valve that supplies water to the aquarium is installed close to the aquarium, it is not covered with a cover, so droplets, dust, dirt, etc. from the aquarium adhere to the solenoid valve, causing it to malfunction. There is a risk that this may occur.

Furthermore, since the solenoid valve is supported by a pipe, it vibrates when the solenoid valve is activated, and the connection part tends to loosen, making it difficult to connect the solenoid valve directly to the pipe at a high place.

The purpose of the present invention is to eliminate these drawbacks, to allow a device for supplying water to an aquarium to be installed close to the side of the aquarium, to prevent malfunctions, and to make the installation work easier. be.

The basic structure of the present invention is that the water stop valve part and the on-off valve part are supported on the support arm of the mounting plate, and the outlet part is located through a notch provided on the upper surface of the cover that covers them at a position that is biased toward the aquarium side. By inserting and protruding the rising part of the gooseneck-shaped discharge pipe facing into the aquarium, the discharge pipe can be prevented from being pinched between the side of the cover and the side of the aquarium, and the cover can be mounted on the mounting plate close to the side of the aquarium. The water supply system is installed on the wall of the building.

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

A in the figure is the main body of the water supply device, which includes an electric drive part a and an on-off valve part 39.
and a water stop valve part 32 are integrally provided.

The on-off valve section 33 and the water stop valve section 32 are integrated into one valve body, and the electric drive section a is integrally attached to the valve body, and the electric motor 13 rotates to control the on-off valve section 33. It is constituted by an electric drive device that converts the reciprocating motion of the valve stem 26.

Therefore, next, this electric drive device (in the embodiment, it is substantially the same as the electric drive section, so the same reference numeral a as the electric drive section)
) will be explained.

12 is a casing of the electric drive device a, 13 is an electric motor installed in the casing 12, 14 is a reduction gear device that reduces and transmits the rotation of the electric motor 13, and 15 is coaxial with the final gear 14n of the reduction gear device 14. This is a rotary shaft provided, and an eccentric cam 16 is provided on this shaft.

Therefore, the rotation of the electric motor 13 is transmitted to the cam 16 at a reduced speed.

17 is a cylindrical flange that connects to the valve body formed in the casing 12, and an insertion hole 19 is provided in the inner bottom of the flange at a position corresponding to the cam 16 in the casing 12.
A puncher guide 19 is formed at the periphery of the insertion hole 18 .

The connecting portion 17 is connected to an opening 23 formed between the inlet 21 and the outlet 22 of the valve housing 20 of the valve body via a cap nut 24 or the like, and the electric drive device a is connected to the valve body. do.

25 is a plunger; one end contacts the cam 16 in the casing 12, and the other end is supported by the plunger guide 19 so as to be slidable forward and backward, and passes through the insertion hole 18 into the connecting portion 17. The valve stem 26 extends into the valve stem 26 and comes into contact with the valve stem 26 .

The valve stem 25 is held in a reciprocating manner by a guide 27 and extends into the valve housing 20, and its tip passes through the valve seat hole 28 to reach the inflow side, and corresponds to the valve seat 29 on the back side of the iron part. A valve body 30 is provided which forms a valve seat seating surface.

The valve body 30 and the valve seat 29 constitute an on-off valve section 33.

Further, a spring 31 is mounted on the valve stem 26 to constantly press the valve seat seating surface toward the valve seat 29 side.

Therefore, when the electric motor 13 is energized and rotates, this rotation is decelerated by the reduction gear device 14 and transmitted to the rotating shaft 15 to rotate the cam 16, and the position where the cam 16 contacts the plunger 25 is the rotating shaft. The plunger 25 moves forward as it moves away from the axis of the spring 3
The valve stem 26 is moved forward against the elastic force of 1 to open the valve.

Conversely, as the position of the circumferential surface of the cam 16 in contact with the plunger 25 approaches the axis of the rotating shaft 15, the resilient force of the spring 31 causes the valve stem 26 and the plunger 25 to move back and close the valve.

At this time, this water supply device main body A is equipped with a changeover switch and a limit switch in the electrical wiring that supplies electricity to the electric motor 13, and automatically controls the operation of the electric motor 13, that is, the stop position of the cam 16, so that when the valve is fully opened, And, when the valve is closed, the valve stem 26 is regulated so that it can be reliably stopped.

The water stop valve part 32 is provided integrally with the valve body between the opening/closing valve part 33 of the valve body and the inlet 21, and opens and closes the flow path by operating the handle.

In addition, the valve body has a discharge pipe 11 formed in a gooseneck shape at its outlet 22 by a rising part 11a extending upward from below, an outlet part 11b hanging down from above, and a connecting part 11C connecting this part. The opening of the inlet 21 is formed so that the water supply pipe 9 can be connected thereto.

The main body A of the water supply device A is attached to the faucet mounting plate 34 and covered with a cover 38 except for the outlet portion 11b and the connecting portion 11C of the discharge pipe 11, and the water supply device of the present invention is installed as shown in FIG. The device main body A is brought close to the side of the water tank 1, the top surfaces of both the water tank 1 and the water supply device main body A are aligned approximately horizontally, and the device is attached to the wall surface 35, and the outlet portion 11b of the discharge pipe 11 protrudes from the cover 38. is faced into the water tank 1, and the tip of the water supply pipe 9 protruding from the wall surface 35 is connected to the inlet 21.

Then, connect the electric drive unit a to a power source, or as shown in FIG.
1 to face the inside of the water tank 1, and remove the hydrant screwed into the water supply pipe 9 in the existing equipment.
and an inlet are used by communicating with each other via a communication water supply pipe 10.

The faucet fixture mounting plate 34 is formed of a metal plate, especially a rust-free metal plate such as stainless steel, so that its back side can be aligned with the building wall surface 35, and screws, etc., for attaching and fixing it to the wall surface 35 are inserted in required places. A hole 36 is drilled.

Further, the faucet fixture mounting plate 34 has a support arm 37 drilled in its front surface, and is supported by the support arm 37 so that the stop valve part 32 and the on-off valve part 33 are held approximately parallel to the wall surface 35. They are arranged in parallel on the wall surface 35.

Further, the cover 38 has two notches 39 and 40 cut inwardly from the rear end on its upper surface.
9.40 has a blind lid 41 that can be inserted and removed freely, and by cutting this lid 41 to an appropriate length, the rising part 11a of the water discharge pipe 11 can be inserted into the notch 40 on the side closer to the aquarium 1, and the other side. The hole 4 through which the communication water supply pipe 10 is inserted into the notch 39 of
2 can be formed respectively.

Note that a solenoid valve may be used as the on-off valve section operated by the electric drive section.

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

■ The rising part of the gooseneck-shaped discharge pipe is inserted through and protrudes from the notch provided on the top surface of the cover that covers the water stop valve, on-off valve, electric drive unit, etc., at a position that is biased towards the aquarium side. When supplying water with the outlet facing the aquarium, the rising part of the discharge pipe is not sandwiched between the side of the aquarium and the side of the cover, allowing the cover and the aquarium to be close together, and the water supply device being installed close to the side of the aquarium. As a result, the piping can be shortened, and the connecting part that connects the gooseneck-shaped discharge pipe and the outlet part only needs to straddle the side wall of the aquarium. Even if the water tank is mounted on a high wall and the distance between the top surface and the ceiling is narrow, the water supply device can be installed without being obstructed by the ceiling, making the installation process easy. up,
Even though the water supply device is installed close to the water tank, the cover can prevent droplets from the water tank from hitting the on-off valve part and the electric drive part, thereby preventing the occurrence of their failures.

Moreover, since the rising portion of the discharge pipe is prevented from swinging back and forth in the front and back direction of the discharge pipe at the notch of the cover, water can be stably discharged into the water tank without tilting the discharge pipe.

■ The water stop valve part and the on-off valve operated by the electric drive part are supported on the support arm of the mounting plate and mounted on the wall surface, so it is easy to install them on the wall at a high place, and the water stop valve part The on-off valves and on-off valves do not rattle, and since they are installed side by side, they do not interfere with each other, making it possible to maintain the water supply pipe to the inlet and adjust the valve opening of the water stop valve to create an automatic siphon. Not only is it easy to adjust the flushing interval of the toilet bowl, but even if the electric drive unit that operates the on-off valve part vibrates, the on-off valve part and the stop valve part are directly fixed by the support arm, so there is no interference with the discharge pipe or water supply pipe. In addition to preventing loosening of the piping connections, the on-off valve is located downstream of the water stop valve, making it possible to repair or adjust the on-off valve or the electric drive part by closing the water stop valve. is easy to do.

■ Since the water stop valve, on-off valve, electric drive unit, and mounting plate are covered, there is no chance of droplets, dust, dirt, etc. from the aquarium adhering to them and causing malfunction.
The opening degree of the water stop valve, which has been carefully adjusted, will not be tampered with.

■ Since the stop valve part and the on-off valve part are arranged parallel to the wall surface, the distance that the cover that covers them protrudes from the wall surface is short, and only the discharge pipe protrudes from the top surface of the cover. This combination of the fact that the water supply device is placed close to the side of the aquarium, the top surfaces of both the aquarium and the water supply device can be aligned almost horizontally, and both can be installed on a high wall surface makes the wall surface tidy. At the same time, high wall space can be used effectively.

■ Since the water supply system is equipped with a stop valve, an on-off valve, an electric drive, a discharge pipe, a mounting plate, and a cover, we will install a new high-tank automatic toilet flushing system that cleans the toilet in a water tank equipped with an automatic siphon. Of course, even in existing high-tank type automatic toilet flushing systems, the water tank equipped with an automatic siphon can be used as is, and the water supply system of the present invention can be installed to electrically control the start and stop of water supply, allowing cleaning. It can be made into an automatic toilet flushing device that can prevent wasteful water consumption.
