(57) [Summary] [Purpose] The odor generated in a toilet that is not flushed is blocked by a water film so that it does not leak upward from the outlet of the toilet bowl. [Structure] A groove 4 is provided below the outlet 2 of the toilet body 1 so as to extend around the entire circumference. A water receiving plate 6 is provided above a part of the groove 4,
Water jetted from the water jet nozzle 7 collides against the water receiving plate 6 to form a water film 17, and the water film 17 causes the discharge port 2
Blockade.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an odor blocking device that forms a water film at the outlet of a toilet bowl for stools to prevent the odor of excretions below from escaping upward.

[0002]

[Prior art]

 Japanese Unexamined Patent Publication No. 50-96035 discloses a water film forming device exclusively for a flush toilet as an odorless toilet. This known device is provided with a bulging edge around the upper end of the outlet of the toilet bowl, so that when the water flows after defecation, the water flow flows inward by the bulging edge to form a water film. is there.

[0003]

[Problems to be solved by the device]

 Since the above-mentioned publicly known technology is used for flush toilets, a water film is formed only when an odor is generated during flushing after defecation, and a water film is formed except when flushing. As it is not used, it cannot be used for toilets that are not flushed with the pump.

An object of the present invention is to obtain a device for continuously blocking odor, which is provided in a toilet used mainly in a toilet of a pumping type.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms an upper opening groove around the circumference of the discharge port provided in the lower part of the toilet body, and provides a drain port at the bottom of this groove, and an upper part of the groove. In addition to providing a water receiving plate on the top of the water receiving plate, a water injection nozzle that forms a water film that sprays water against the upper surface of the water receiving plate to form a water film that covers the discharge outlet is used to block odors. did.

[0006]

[Action]

 Since the present invention has the above-mentioned configuration, when water is jetted toward the water receiving plate below the water jet nozzle provided in a part of the periphery of the discharge port at the lower part of the toilet bowl, the water colliding with the water receiving plate Spreads like a film, hits the peripheral wall of the outlet while covering the outlet, flows into the groove below and flows from the outlet. For this reason, the odor generated from the excrement accumulated in the toilet bowl is not emitted to the upper part of the toilet bowl.

[0007]

【Example】

 In the embodiment shown in the figure, 1 is a toilet body, and a discharge port 2 is provided in the lower portion thereof. Reference numeral 3 denotes a hollow ring-shaped water tank which is fixed to the lower portion of the main body 1 by means such as screwing, and the center of the water tank 3 penetrates vertically and communicates with a discharge port 2.

An upper open groove 4 is formed in the upper part of the inner circumference of the water tank 3 and its bottom is inclined, and a drain port 5 communicating with the inside of the tank 3 is provided at the lowest part thereof. .

Reference numeral 6 is a water receiving plate provided on a part of the upper portion of the inner wall of the groove 4. The water receiving plate 6 is, for example, a stainless steel plate having a thickness of about 0.8 to 1.0 mm bent into an inverted L shape, and its plane shape is as shown in FIG. 4 (I) or (II). ing. Reference numeral 7 denotes a water jet nozzle made of a stainless pipe or the like, which is mounted in the main body 1 so as to be able to move up and down, and a jet port 8 at the lower end thereof faces the water receiving plate 6.

As shown in FIG. 2, the upper end of the nozzle 7 is slidably fitted in the large diameter portion 10 at the lower end of the water supply pipe 9 embedded in the main body 1, and is kept watertight by the rubber ring 11. Reference numeral 12 is a recess provided in a part of the main body 1. A part of the nozzle 7 is exposed in this recess, and the nozzle 7 is fixed by fastening the stopper plate 13 with a screw 14.

Therefore, when the screw 14 is loosened, the nozzle 7 moves up and down, and the space between the jet port 8 and the water receiving plate 6 can be adjusted. The recess 12 is closed by a detachable lid 15 fixed by means such as screwing. The water supply pipe 9 is guided into the water tank 3 as shown in FIG. 1, and is connected to the discharge port of the submersible pump 16.

In the above configuration, when the submersible pump 16 is operated under the condition that the water tank 3 is filled with water, the water in the tank 3 flows into the water supply pipe 9 and the ejection port 8 of the nozzle 7 is discharged. It jets out from and collides with the water receiving plate 6.

The shape of the water receiving plate 6 is made appropriate, the gap between the jet port 8 of the nozzle 7 and the water receiving plate 6 is made an appropriate value such as 0.1 to 0.5 mm, and the water pressure is made appropriate. When adjusted to, the water hitting the water receiving plate 6 becomes a water film 17 as shown by the chain lines in (I) and (II) of FIG.

Therefore, if a value such as water pressure is set so that the peripheral edge of the water film 17 reaches the inner surface of the outer wall of the groove 4, the inner peripheral surface of the water tank 3, that is, the discharge port 2 is completely blocked.

As described above, all the water that has formed the water film 17 and hits the outer peripheral wall of the groove 4 falls into the groove 4, and the circulation returning from the drain port 5 back into the water tank 3 is repeated.

The water film 17 is formed so that not only excreted matter but also toilet paper passes through such water pressure that toilet paper or the like flows laterally by water pressure and flows into the groove 4. It does not block the drain port 5 and the like. The pump 16 continuously forms the water film 17 in continuous operation.

[0017]

【effect】

 As is clear from the above description of the structure and operation, the discharge port at the bottom of the toilet bowl is completely sealed with a water film, so even in the case of a toilet without flushing, the odor of excrement in the toilet bowl is There is no danger of leaking upward from the outlet of the main body.
