It is surrounded by a horizontal wall 5 extending in the left-right direction between the urine collection ball wall 3 and the upper extension 3a, and left and right side walls 6, 6 (see FIG. 14). A single odor outlet 7 for extracting odor from the ventilation cavity 28 is provided at the center of the upward extension 3a of the urine collection bowl wall 3, which forms the back surface of the urinal 1. Further, the front left and right corners of the ventilation cavity 28 are provided so as to extend into the odor supplementing spaces C and C, and odor suction ports 8 (see FIGS. 13 to 15) are provided on the left and right sides of the horizontal wall 5, respectively. They are opened one by one.

As shown in FIG. 13, the water passage cavity 27 includes an introduction section 27a formed with the ventilation cavity 28 interposed on the central lower surface side of the urinal top surface 2, and an introduction section 27a formed from the rear of the introduction section 27a to the left and right.

The urine is discharged toward the inner surface of the urine collection ball 15.
The washing water becomes dirty water and is discharged to the outside from the discharge port 22 via the trap 23. The odor rising inside the urine collection bowl 15 naturally rises to the odor collecting spaces C and C.
, and from the odor suction ports 8, 8 to the ventilation cavity 28.
After being sucked in, the odor is discharged to the outside through the odor outlet 7. Note that a suction blower 26 is connected to the odor outlet 7 via an air conduit 24 and a duct 25, as shown in FIG. Air conduit 24
The duct 25 is hidden behind the wall surface to which the urinal 1 is attached, and is hidden from the user's eyes.

[The problem that the idea attempts to solve]

In the case of the urinal 1 having the deodorizing function, since there is only one odor outlet 7 opened in the ventilation cavity 28, the amount of exhaust air necessary for deodorization is ensured, and the exhaust air passing through the odor outlet 7 is secured. In order to prevent noise from being generated by the odor discharge port 7, it is necessary to increase the inner diameter of the odor outlet 7 (for example, about 45 mmφ). However, in order to increase the diameter of the odor outlet 7,
It is necessary to increase the height of the ventilation cavity 28, and the height H of the upper distribution section D of the urinal 1 shown in FIG. 12 necessarily increases. However, increasing the height H of the upper distribution part D causes the following problems.

(a) As a result of increasing the weight of the toilet, manufacturing costs increase and handling during construction becomes difficult.

(b) When molding the base material of the urinal 1 by slurry casting, the inner mold for molding the ventilation cavity 28 of the upper distribution part D (in addition, the water passage cavity 27
The inner distribution portion 27b and the like are formed by joining clay pieces together after slurry casting. ) because the insertion height dimension becomes large, it becomes very difficult to cut out the mold and may damage the molded base. As a result, the yield of base molding decreases.

(c) The ratio of the height H of the upper distribution part D to the total height of the urinal 1 becomes large, resulting in an unsightly urinal.

In addition, the odor outlet 7 is made into a horizontally elongated oval shape,
It is also conceivable to reduce the height dimension H of the ventilation cavity 28. However, in this case, it is necessary to use a special shape for the air conduit 24 that connects to the odor outlet 7, and it also makes the connection work difficult, which creates a different problem that significantly reduces the toilet construction efficiency. I will invite you.

In order to solve the above-mentioned problems, the present invention is a small toilet with a deodorizing function that can reduce the height of the ventilation cavity provided at the top of the urinal, which has an odor outlet on the back side of the urinal. The purpose is to provide toilet bowls.

[Means to solve the problem]

The means adopted by the present invention is to provide a water passage cavity that communicates the flushing water outlet that discharges flushing water onto the wall surface of the urine collection bowl with the flushing water inlet opened at the top of the toilet bowl, and to eliminate the odor inside the urine collection bowl. In a urinal having a deodorizing function that is provided with a ventilation cavity that communicates between an odor suction port for sucking and an odor discharge port opened at the top of the toilet bowl, the water passage cavity is formed on the back side of the top of the toilet bowl. The vent includes a back side distribution section that communicates with the flushing water outlet, and a front side distribution section that is formed on the front side of the upper part of the toilet bowl and communicates with the rim passageway on both sides and communicates with the back side distribution section at the center. The storage cavity extends from the back side of the toilet bowl across the upper part of the back distribution part to between the back distribution part and the front distribution part, and connects the odor suction port between the back distribution part and the front distribution part. The odor outlet is opened between the side distribution part and the odor outlet is inserted through the back wall of the toilet at two symmetrical positions on the back of the toilet.
This is because the holes were drilled separately.

[Effect]

The odor that rises inside the urine collection bowl naturally rises to reach a space between the rear side distribution section and the front side distribution section of the water passage cavity provided at the top of the toilet bowl, and is sucked into the odor suction port. The sucked odor passes through the ventilation cavity and is discharged to the outside of the toilet bowl from the two odor discharge ports. Since two odor exhaust ports are provided at symmetrical positions on the back of the toilet bowl, the diameter can be made smaller than in the past, and the height of the ventilation cavity can be reduced.

[Effects of this invention]

As detailed above, the proposed toilet has two odor evacuation ports at symmetrical positions on the back of the toilet. Since the height of the cavity can be reduced, the following practical effects are achieved.

Since the necessary exhaust air volume can be secured without increasing the weight of the urinal, it is possible to provide a urinal that is manufactured at a lower manufacturing cost than conventional ones and is easy to handle during construction.

When molding the base of a urinal by slurry casting, the insertion height of the inner mold can be reduced, so the mold can be easily removed compared to the conventional method and the molded base will not be damaged. As a result, the yield of base molding is improved.

The ratio of the height of the upper distribution part to the total height of the urinal can be kept in a well-balanced ratio, and the piping connected to the odor outlet is on the back side of the urinal and out of sight, resulting in a good appearance. Urinals can be provided.

Furthermore, the proposed toilet includes a back side distribution part and a front side distribution part in the water passage cavity, and the ventilation cavity extends between the back side distribution part and the front side distribution part, and the back side distribution part Since the odor suction port is opened between the front side distribution section and the front side distribution section, it has the following practical effects.

The inner surface of the urine collection bowl can be evenly washed because the washing water is distributed and smoothly guided between the back side distribution part and the front side distribution part.

The odor rising due to hot air is captured by the wall forming the ventilation cavity and the rear distribution section, and the captured odor is sucked into the exhaust suction port opened between the rear distribution section and the front distribution section, so it is efficient. Can emit odor.
