Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to deodorization in a hand-washing room among sanitary equipment.

(Prior art) Conventionally, as a device for eliminating odors in a handwash room
-27932 is shown in FIG. 1 (FIG. 3 of the present application drawing). Briefly describing FIG. 3, the inner cylinder seat 32 inside the floor trap body 31 is provided with a discharge port 34 by a surrounding receiving plate 33.
An inner cylinder 37 having a projecting edge 36 extending from a slanted bottom 35 is supported at the lower part of the lower part of the base, and a lower part of the discharge port 34 corresponding to the projecting edge 36 is slightly outwardly projected to open and close an inclined blocking plate 38. The upper part is hinged freely, and the flange 41 of the cylindrical cover 40 faces the water reservoir 39 formed by the inner cylinder seat 32 and the receiving plate 33 of the inner cylinder 37.

In the above case, since the water level in the water reservoir evaporates over time (especially in summer), the odor-containing gas rising in the drainage pipe is covered by the barrier plate. In many cases, it passed through the water reservoir through the gap between the discharge ports and entered the hand washing room. Therefore, there is an inconvenience that even if only the odor is generated, the handwash room is filled with the odor and the discomfort is increased.

Furthermore, since the wash water in the water reservoir is washed away from the washroom or the floor in the bathroom, it contains a lot of foreign matter such as hair and dust, and the trap body easily becomes clogged and must be cleaned frequently. There wasn't.

(Problems to be solved by the device) The problem to be solved by the device is to always maintain the water level of the water trap of the floor trap at a necessary water level capable of blocking passage of odors. It is to make it difficult for foreign matter to enter the floor trap.

(Means for Solving the Problem) The technical means taken by the present invention to solve the above-mentioned problems is a floor trap which is provided below the floor surface of a hand-washing room and removes washing water. A drain fitting with the discharge port facing the downstream side is attached to the water reservoir, and a pipe joint with the water receiving port facing the upstream side is attached to a part of a separately provided supply pipe for cleaning the urinal. A drainage means for odor prevention is constructed by connecting a pipe joint and the drain fitting with an embedded pipe, and a part of the wash water that passes through the supply pipe is supplied to the water trap of the floor trap each time the urinal is used. By doing so, the water level necessary for stopping the odor of the water reservoir can be constantly maintained.

(Function) Every time the urinal is used, a part of the wash water is supplied to the water trap of the floor trap through the buried pipe of the drainage means each time the urinal is used, so that the water level necessary to block the odor of the water trap is constantly maintained. maintain.

(Embodiment) An embodiment of the present invention will be described below in detail with reference to the drawings.

The embodiment of this invention is shown in FIGS. 1 and 2 (a) and (b).
As shown in FIG. 1, the drainage means 1 includes a buried pipe 2 arranged below the floor surface B of the handwash room A and one end of the buried pipe 2 at
Attached to a part of the supply pipe 3 of the urinal C for men provided in the above, and a pipe joint 4 which opens the water receiving port 10 toward the upstream side, and the other end of the buried pipe 2 and the hand washing chamber A It is constructed as follows by the drainage fitting 7 attached to the water reservoir 6 of the floor trap 5 described later, which is preliminarily buried under the floor surface B of FIG. The floor trap 5 has a mesh seat 8 on the inner upper side and an inner cylinder seat 9 on the lower side, and a horizontal receiving plate 12 corresponding to the inner cylinder seat 9 on the outer circumference of the inner cavity 11 for the inner wall. Formed in the shape of a plate
An inner cylinder 13 is formed by joining and fixing 12 and the inner cylinder seat 9, and the water reservoir 6 is formed by the upper edge 14 of the inner cylinder 13 and the receiving plate 12, and the water reservoir 6 is inserted. The drainage fitting 7 with the discharge port 16 facing the downstream side is attached to the hole 15 and the drainage fitting 7 is attached.
Is connected to one end of the buried pipe 2. The inner cylinder 13
The discharge port 16a provided below the inclined bottom 17 has a blocking plate 19 which is opened by an internal pressure during drainage via a hinge 18 and is closed by its own weight when the internal pressure decreases. The inner cylinder cover 20 is fixed to the lower end of a support rod 23 connected to a cover plate 22 having a grid 21 on the mesh seat 8, and the lower edge 25 of the flange 24 of the inner cylinder 13 is the upper edge 14 of the inner cylinder 13. It is configured to be lower than the plane. In the urinal C of the embodiment, the flush water is discharged manually by the push button 26. However, the urinal is not limited to the one having the fully automatic cleaning function and is not limited. To do.

Now, when the push button 26 is operated before and after using the urinal C in the hand-washing room A, the washing water is discharged into the urinal C through the supply pipe 3 in the usual manner for washing.
At this time, a small amount of washing water is successively introduced into the supply pipe 3 from the water receiving port 10 of the pipe joint 4 which is open toward the upstream side as shown in FIG. The discharge port 16 of FIG. 2 (b) that flows down through the pipe 2 and reaches the drainage fitting 7 from the end of the buried pipe 2 and opens downstream of the drainage fitting 7.
Is discharged to the water reservoir 6 of the floor trap 5 through the
When the constant water level W necessary to block off the odor inside is exceeded, it flows down from the upper edge 14 of the inner cylinder 13 into the inner cylinder 13, and flows from the inclined bottom 17 of the inner cylinder 13 toward the discharge port 16a side. Since it is excluded from 16a, the constant water level W of the water reservoir 6 always holds the necessary amount.

(Effects) The present invention has the following advantages because of the above-described configuration.

(1) In the middle of the supply pipe of the urinal in the hand-washing room, a pipe joint with the water receiving port facing upstream is attached, and a buried pipe is provided between the pipe joint and the floor trap provided under the floor of the hand-washing room. The drainage means and the water receiving port are connected by the drainage fitting for the water trap of the floor trap.Therefore, every time the urinal is used, a part of the washing water passing through the supply pipe passes through the drainage means and the drain fitting. The constant water level, which is supplied to the water reservoir of the floor trap and is necessary for shielding the odor of the water reservoir, can always be maintained at the required water level without being affected by changes in the outside temperature.

(2) Since the cleaning water supplied to the water trap of the floor trap is supplied directly from the main tap, not from the waste water that has been used once, foreign substances do not accumulate in the floor trap, and the floor trap can be prevented. .

(3) Unlike the conventional one, the drainage fitting facing the water trap of the floor trap has its discharge port directed toward the water trap side on the downstream side, so the water level in the water trap suddenly increases. Even if there is, there is no possibility of splashing water splashes from between the floor trap lattices and wetting the floor of the washroom.
