Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a faucet-type urinal that cleans the inside of the toilet bowl with water.

<Prior Art> In order to clean this type of urinal, it is necessary to thoroughly distribute the cleaning water over the entire rear wall, which is the cleaning surface of the urinal.

Therefore, conventional urinals, for example,
As disclosed in Japanese Patent No. 14755, by opening water spray holes at appropriate intervals along the rear wall surface at the upper end of the rear wall, cleaning water is discharged from the water spray holes to clean the rear wall. Was. In this case, since the washing water discharged from the water sprinkling holes does not spread widely in the horizontal direction, a large number of water sprinkling holes are formed in order to eliminate cleaning leakage in areas that are not located directly below the water sprinkling holes.

<Problems to be solved by the invention> Such conventional urinals require a large amount of flushing water in order to evenly discharge flushing water from all the water sprinkling holes. Therefore, if the amount of washing water is reduced in order to conserve water, the washing water will not reach all the watering holes and there will be areas where no water will flow, making it impossible to thoroughly wash the entire rear wall. There is a problem with getting dirty.

SUMMARY OF THE INVENTION In view of the conventional problems, an object of the present invention is to provide a urinal that can thoroughly clean the entire rear wall even if the amount of flushing water is small, thereby saving water.

<Means for solving the problem> The technical means taken by the present invention to solve the above problem is to install a roughly semicircular shape that is convex downward when viewed from the front, at the center of the upper end of the rear wall. When viewed from the front, a plurality of sagging watering holes are drilled radially on the lower surface of the watering chamber, close to the front of the rear wall, with the discharge side of these sagging watering holes facing the rear wall. ~
In addition to tilting the pipe at a 40° angle, the water supply pipe that supplies water to the sprinkler room is equipped with a manual valve that adjusts the instantaneous flow rate according to the water pressure, and an electric valve that allows water to flow for a certain period of time by operating a cleaning switch. .

<Function> The function of the present invention is to supply cleaning water to the water sprinkling chamber at an instantaneous flow rate above a certain level using a manual valve and an electric valve installed in the water supply pipe, and to drain the cleaning water discharged from the water sprinkling hole into the water supply chamber. It is applied to a wall and diffused in a fan shape, allowing it to flow down over the entire rear wall.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, as shown in Fig. 1, the water supply is connected to the urinal main body A via a manual valve B and an electric valve C. The manual valve B adjusts the instantaneous flow rate according to the water pressure, and the electric valve C is one in which water is passed for a certain period of time by operating the cleaning switch D.

FIGS. 1 to 3 show the rear wall 3 and the drip receiving portion a from the dripping watering hole 1 and the dripping watering hole 2.
This shows the case of a general urinal in which water is flushed and drained naturally through trap 4 due to the water level difference.

The urinal main body A extends the peripheral edge of the rear wall 3 to form a drip receiving part a having a trap 4 and a peripheral wall part b having a rim passageway 5, and a water supply chamber c in the upper part of the rear wall 3. Form into one body.

The water supply chamber c includes the upper part of the rear wall 3, the upper wall 6, and the partition wall 7.
A water supply port 8 is formed in the upper wall 6, and a water supply pipe 9 connected to the electric valve C is connected to the water supply port 8, and a through hole 10 is formed in the partition wall 7. The water supply chamber c is connected to a water sprinkling chamber d formed below the water supply chamber c, and the cleaning water flowing into the water supply chamber c from the water supply port 8 is supplied to the water sprinkling chamber d through a through hole 10.

In addition, a port 11 communicating with the rim passageway 5 is formed in the water supply chamber c, and washing water is supplied to a plurality of drip receiving sprinkling holes 2 which are opened in the rim passageway 5 at appropriate intervals.

The water sprinkling chamber d is formed across the partition wall 7 and the rear wall 3, and its shape is formed in a downwardly convex arc shape when viewed from the front. 1 stagnant watering hole for each
is drilled close to the rear wall 3.

This stagnant water sprinkling hole 1 has its discharge side inclined at 20 to 40 degrees toward the rear wall 3 side, and this water sprinkling hole 1
The cleaning water discharged from the rear wall 3 hits the rear wall 3 and spreads in a film shape in the left and right direction.

In the drawings, a slight gap 12 is provided between the discharge side of the sprinkler hole 1 and the rear wall 3, but the invention is not limited to this. good. Further, although the number of holes is one on each side, it is not limited to this, and several holes may be opened depending on the size of the urinal main body A.

Thus, a through hole 10 communicating with the stagnant water sprinkling hole 1 is provided.
Then, the vents 11 communicating with the drip pans 2 are opened so as to distribute the cleaning water in the water supply chamber d at the same rate, and the manual valve B is adjusted to adjust the instantaneous flow rate of the cleaning water to 25~30%. If water is supplied at a rate of 1.2 min, the urinal can be flushed with just 1.2 liters of water, compared to the 4 to 6 liters required for conventional urinals of the same type.

Next, FIGS. 4 to 7 show the case of a so-called blow-out type urinal, in which the filth in the trap 4 is drawn together with accumulated water into a drain pipe (not shown) and blown away by a strong jet of water from the jet hole 13. show.

This blowout type water supply chamber c has a through hole 10 communicating with the stagnant water sprinkling hole 1 and a through hole 11 communicating with the drip receiving water sprinkling hole 2, as well as a through hole 15 communicating with the water passage 14.

The water passage 14 hangs down from the back side of the rear wall 3 and communicates with a water storage chamber 15 formed below the trap 4. A jet hole 13 is provided diagonally rearward in a partition wall 16 that separates this water storage chamber 15 from the trap 4. It is opened at an angle.

In the lower surface of the water sprinkling chamber d, similar to the above-described embodiment, one water sprinkling hole 1 is opened on each side, and the discharge side thereof is inclined at an angle of 20 to 40 degrees toward the rear wall 3 side.

Thus, the through holes 10 communicating with the stagnation water sprinkling hole 1, the through holes 11 communicating with the drip receiving water sprinkling hole 2, and the through holes 15 communicating with the jet hole 13 are each 25 to 35%
By opening the water supply chamber C to distribute cleaning water at a rate of 25 to 35% and 35 to 45%, and supplying water at an instantaneous flow rate of 40/min using manual valve B, the blowout that conventionally required approximately 10% can be achieved. Even a type urinal can be sufficiently flushed with the amount of water in 2.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

By supplying cleaning water to the sprinkling chamber at an instantaneous flow rate above a certain level using a manual valve and an electric valve connected to the water supply pipe, the cleaning water discharged from the stagnant sprinkling hole is applied to the rear wall and spread in the left and right directions. The water can be diffused in a large fan shape and flowed down over the entire rear wall, and even if the amount of cleaning water is small, the entire rear wall can be thoroughly cleaned. Therefore, it is 1/2 the size of conventional urinals of the same type without compromising the cleaning effect.
Since the cleaning function can be achieved with ~1/5 of the amount of cleaning water,
You can save water.

Since multiple water sprinkling holes are drilled radially when viewed from the front, the cleaning water in the water sprinkling chamber can be flowed down radially over a wide area toward the rear wall, covering the entire surface of the rear wall. It can be spread widely.
