Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure and a device of a toilet bowl for eliminating unpleasant falling sound made onto a standing water surface in the bowl when a male urinates standing by a flush toilet bowl. <P>SOLUTION: The device eliminates sound hitting the water surface by raising a toilet seat immediately before urination to temporarily drain and remove only a standing water part in the bowl in a falling range of urine, thereby putting the inside of the toilet bowl in that range into a waterless state to naturally cause no sound. Moreover, the device is structured to prevent reverse-flow odor from sewage during use. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a toilet structure and device that eliminates falling sound that occurs when a urinal is in a flush toilet and hits the surface of a stored water.

  The structure of a conventional flush toilet has a siphon type structure to prevent backflow intrusion such as sewage odors and insects, but this structure has an indispensable water storage part, and if urination is released toward the water surface, There was a drawback that an unpleasant falling sound called jobo-jobo was unavoidable.

In particular, in the case of a floor plan where the toilet is in close contact with the living room, dining room, bedroom, etc. in the house, this falling sound is very unpleasant for both the urine and the audible side. In order to eliminate the water, it was necessary to use excess water or to avoid the water surface.
JP 10-338957 A

  The problem to be solved is how to temporarily remove the portion of the water in the range where the urine hits immediately before use, and how to prevent the backflow odor from the sewage even after the removal.

  Due to the structure of the conventional siphon-type toilet, if all the accumulated water is drained and removed, a sewage odor will be introduced. Therefore, in the structure of the present invention, the shape of the partition wall 6b of the present invention is newly provided in the shape of the drainage channel entrance partition wall 6a of the conventional siphon type toilet, and the drain port 14 is installed at a position higher than the tip of the partition wall 6b. Thus, even after the accumulated water portion 8 is drained from the drain port 14, the accumulated water portion 9 that is the amount of water up to the second water level line 7b remains without being drained.

  The device of the present invention is a device that temporarily removes only the water storage portion 8, and by raising the toilet seat 1 immediately before using the urine, the wire connected to the change-over switch 2 is pulled to operate the opening / closing operation panel 10 and to open / close the drainage device. 12, the wire tip 13 is raised, the drainage opening / closing lid 15 is pushed up, the drainage port 14 is opened, and only the pooled portion 8, which is the range where the urine hits, is drained, and the bowl in that range becomes waterless. Is a mechanism to eliminate the falling sound because it falls to the empty bowl inner surface.

  Due to the structure and apparatus of the present invention, the pooled water in the bowl where urine falls is drained and becomes anhydrous, so the urine falls on the empty toilet bowl inner surface. Will be eliminated and the toilet will be extremely quiet and comfortable. In particular, even in the case of a floor plan where a toilet is in contact with a living room, a dining room, a bedroom, etc. in a house, urination can be performed without worrying about the surrounding ears. In addition, since the urine falls to the inner bottom surface of the bowl, there is an advantage that the sanitation around the toilet bowl can be maintained by preventing splashing that occurs when the urine hits and hits the conventional water surface.

The toilet of the present invention is a toilet that can be used without sacrificing conventional functions and appearance, can be used simply and simply by raising and lowering the toilet seat in the usual procedure before using a urine, and can be used cleanly without power.

  First, since the toilet seat is always lifted immediately before the use of the urine, the changeover switch 2 utilizing this action is springed up by the spring, and the rotating blade 11a of the opening / closing operation panel 10 is pulled in the direction D through the wire 3a. 11b is pushed in the opposite E direction and the tip 13 of the connected wire 3b jumps up, and at the same time the drainage opening / closing lid 15 is pushed up to open the drainage port 14. From here, the water storage portion 8 reaches the second water level line. 17 is drained into sewage. (See Figs. 1 and 6)

At the end of the urination, the changeover switch 2 is pushed down by lowering the toilet seat 1, the rotary blade 11a of the opening / closing operation panel 10 is pushed out in the F direction, and at the same time, the rotary feather 11b of the operation panel is pulled and connected in the opposite G direction. At the same time, the tip 13 of the wire 3b is lowered, the drainage opening / closing lid is lowered, the drainage port 14 is closed, and the water supply returns to the full water level up to the first water level line 7a. (See Figs. 2 and 7)

Since the drainage open / close lid 15 is an independent instrument equipped with a dust tray 21, it can be pulled out even if paper or dust is jammed in the drainage port 14, and cleaning inspection can be facilitated.

An inspection port (FIG. 12) is provided from the front to the side of the toilet to facilitate inspection and cleaning of the open / close operation panel, drainage switchgear, drain trap pipe, sewage pipe, and the like.

In particular, it has an appropriate use as an attentive toilet that is indispensable for installation in small houses, studio apartments, business hotels, small offices, and private rooms.

Claims (8)

In standing flush urinals in flush toilets, it has a device and structure that eliminates the sound generated when urine falls on the surface of the water in the toilet bowl. It is a device that eliminates the sound hitting the water surface by draining and emptying.   The above-mentioned device is a device that drains only the pooled water portion 8 in the toilet bowl where urine falls, and a drain outlet is provided in the bottom of the bowl, and an opening / closing operation panel 10 and a draining switch 12 are installed in the toilet bowl cavity 22. When the toilet seat 1 is raised, the changeover switch 2 is activated to push up the wire tip 13 of the drainage switchgear connected to the open / close operation panel, and at the same time, the drainage open / close lid 15 is opened. Is drained, and the reservoir 9 remains undrained.   With the above structure, if all the water in the toilet bowl is drained, the structure of the siphon-type toilet will cause a backflow odor from the sewage, so it is necessary to leave the water storage portion 9 to prevent this. is there. Therefore, the shape of the partition wall 6b of the present invention is newly added to the shape of the drainage channel entrance partition wall 6a of the conventional siphon type toilet, and the second water level line is provided by installing the drain port 14 at a position higher than the tip of the partition wall 6b. The accumulated water portion 9 having the amount of water up to 7b can be left without being drained, and has a double partition structure that prevents backflow odor due to its effect.   The inside of the drainage switch 12 is waterproof, and the drain switch 14 is opened and closed by moving up and down the wire tip 13 that is movably connected to the changeover switch 2 and the opening / closing operation panel 10 so that the stored water portion 8 is drained or stored. It is a device that is.   The drainage switchgear 12 drains the pooled portion 8 from the drainage port 14 to the sewage pipe 18 through the drainage trap pipe 17, but also secures the pooled water portion 16 to prevent backflow odor from the drainage port 14 after drainage. It has a shape and device that can be used.   The opening / closing operation panel 10 is a device that raises and lowers the toilet seat 1 to move the rotary wing 11 to the left and right via the changeover switch 2 and the wire 3a so that the tip 13 of the wire 3b is moved up and down to open and close the drainage opening / closing lid 15. It is.   All the devices of the present invention are housed in a toilet bowl except for the changeover switch at the upper edge of the toilet bowl and the drainage opening / closing lid at the bottom of the bowl.   Since the drainage opening / closing lid 15 is an independent instrument with a garbage tray 21 attached, it can be pulled out and removed even if paper or dust is jammed in the drainage port 14, facilitating cleaning and inspection.
