Rim water passage 27d connected to the passage 27c
Has become As shown in FIG. 7, the introduction chamber 27a is
Bottom wall 10 faces above urine collecting part 15. The introduction chamber 27a and the back side distribution passage 27b are communicated with each other by a distribution port 20 provided in the side wall 11 of the introduction chamber 27a, and the introduction chamber 27a and the front side distribution passage 27c are connected to each other.
A communication port 13 is provided in the rear road wall 9 of the vehicle c.

The wash water sent from the water supply source to the urinal 1 flows into the introduction chamber 27a from the water supply port 12 formed in the upper portion 3a of the urine collection wall 3, and then from the communication port 13 to the front side distribution passage 27c. 20 to the inner distribution passage 27b. The wash water distributed to the back side distribution passage 27b is discharged from a water discharge port 19 formed in the bottom wall 18 at appropriate intervals, and flows down while washing the surface of the urine collection wall 3. In addition, the front distribution path 27
The washing water distributed to c flows into the rim water passage 27d and is ejected from the water discharge port 16 formed in the lower portion to the urine collection ball portion 30 below the urine collection wall 3. After that, the cleaning water flows into the trap portion 22 and is discharged to the outside through the discharge port 23.

Next, the exhaust passage 28 will be described. In this urinal 1, as shown in the drawing, an exhaust passage 28 is formed in the flush water passage 27 immediately above the introduction chamber 27a. That is, in the exhaust passage 28, the upper and lower sides are defined by the top wall 2 of the urinal 1 and the partition bottom wall 5 with the introduction portion 27a, and the left and right side walls 6, 6
Thus, the front and rear are chamber-like ones each surrounded by the partition standing wall 4 with the introduction portion 27a and the urine collection wall upper portion 3a of the urinal 1. An exhaust port 7 is formed in the upper portion 3a of the urine collection wall,
An exhaust device including a conduit 24, a duct 25, a suction blower 26, etc. is connected. Further, the partition bottom wall 5 of the exhaust passage 28 is provided so as to project to the left and right sides of the introduction chamber 27a, as shown in the right half of FIG. The odor collecting space C is a space portion above the urine collecting portion 15 formed between the front road wall 21 of the rear distribution passage 27b and the rear road wall 9 of the front distribution passage 27c. The compartment bottom wall 5 is provided with one intake port 8 on each of the left and right sides, and connects the exhaust passage 28 and the odor collecting space C to each other.

The odor generated in the urine collecting part 15 when the urinal 1 is used naturally rises and reaches the odor collecting space C. By operating the exhaust device connected to the exhaust port 7, the odor is sucked from the intake port 8 into the exhaust passage 28 and immediately discharged from the exhaust port 7 to the outside.

[Problems to be solved by the device]

The conventional urinal 1 is a wall-mounted type which is attached to a wall surface using a bracket. By the way, when the urinal 1 is mounted on the wall surface, at the same time, the connecting work between the conduit 24 of the exhaust device and the exhaust port 7 of the exhaust passage 28 must be performed. However, in the wall-mounted type, as shown in FIG. 11, the upper part of the back part 31 of the urinal 1 is hooked on the bracket 32 fixed to the wall surface W, and only the lower part is pulled toward the front side. The work space S must be provided between the back 31 of the urinal and the wall surface W by tilting it. However, since the exhaust port 7 is formed at the uppermost portion of the urinal 1, the work space for connecting the conduit 24 is the narrowest space portion of the work space S. Therefore, in the conventional urinal 1, it is very difficult to connect the exhaust device. Moreover, since the exhaust port 7 and the wall surface W are very close to each other, the conduit 24
A gasket to be inserted between the exhaust port 7 and the urinal 1
It was often pinched between the back part 31 and the wall surface W and damaged.

Further, the shape of the exhaust port 7 is formed in a circular shape in consideration of the efficiency of the connecting work with the conduit 24 and the sealing property after the connection. Then, in order to keep the odor suction efficiency and suppress the generation of noise, it is necessary to secure an opening area of a certain extent or more, so the diameter of the exhaust port 7 must be increased. Therefore, the height of the exhaust passage 28 must be increased, so that the height H of the upper portion of the urinal 1 (7th
(See the figure) becomes larger. Therefore, there is a drawback that the urinal 1 is increased in size and weight, and the molding becomes difficult and the handling becomes difficult.

[Means for Solving the Problems]

The present invention was devised to provide a urinal that is easy to connect to an exhaust device and has excellent deodorizing efficiency. A feature of the present invention is that it has a cleaning passage that connects a water outlet that opens to the urine collecting part and a water supply port that is formed in the upper part, and an intake port that opens above the urine collecting part and an exhaust port that opens on the back side. Is a urinal in which the exhaust passage communicating with the urinal is provided separately from the flush water passage, and the exhaust passage is formed by being surrounded by a side wall, a back wall and a urine collecting wall at a rear side corner of the urinal, The intake port is provided above the exhaust passage forming portion of the urine collection wall, and the exhaust port is provided in the exhaust passage forming portion of the rear wall.

[Action]

In a urinal of a type in which a back part is closely attached to a wall surface, a back wall is usually formed on the left and right sides of the back part in order to ensure strength after demolding. Therefore, a space portion surrounded by the side wall, the back wall, and the urine collection wall is formed in the up and down direction at the inner corner of the urinal. According to the present invention, the exhaust port can be provided in the back wall of the urinal by utilizing the space formed in the rear side corner as the exhaust passage. Therefore, it is possible to provide the exhaust port at a low position. Further, by providing the exhaust port at a low position, it is possible to prevent the height of the urinal having the exhaust passage from increasing. Furthermore, since the intake port provided in the upper part of the urine collection wall can be formed into a desired shape, it is easy to adopt a shape with a good odor suction efficiency.

〔Example〕

The details of the present invention will be described below with reference to FIGS. 1 to 5 showing an embodiment.

As shown in the drawings, the flush water channel of the urinal 40 according to the present invention has a structure substantially similar to the conventional one. That is,
Left and right standing walls 44 and bottom walls 57 are provided at the center of the upper part of the urine collecting part 70.
And the urine collection unit 70
A rear side distribution passage 45 provided along the urine collecting wall upper portion 50 in an upper portion of the urine collecting portion 70, and a front side distribution passage 52 provided along an inner side of the front wall 53 of the urinal 40 in an upper portion of the urine collecting portion 70. A rim water passage 51 is provided on the front side of the urinal 40 along the peripheral edge of the opening of the urine collecting part 70 and is connected to a front side distribution passage 52. As shown in FIG.
The bottom wall 57 of the introduction chamber 43 is provided with a distribution port 42 for distributing the cleaning water to the inner distribution passage 45. A communication port 55 communicating with the introduction chamber 43 is provided in the rear road wall 54 of the front distribution passage 52.

The wash water sent from the water supply source to the urinal 40 is collected on the urine collection wall 6
0 from the water supply port 41 formed in the upper portion 50 to the introduction chamber 43
To the rear side distribution passage 45 from the distribution port 42 to the communication port 5
5 to the front distribution path 52, respectively. The cleaning water distributed to the back side distribution passage 45 is discharged from a water discharge port 45a which is formed in the bottom portion at appropriate intervals. Further, the wash water distributed to the front side distribution passage 52 flows into the rim water passage 51 and is discharged from a water discharge port (not shown) formed in the lower portion.

The exhaust passage 47 in this embodiment is, as shown in FIG.
On the left and right sides of the back side corner of the urinal 40, the back wall 46,
It is provided by utilizing a space portion having a triangular cross section formed by being surrounded by the side wall 49 and the urine collection wall 60.

The intake port 48 is provided in the exhaust passage forming portion in the upper portion 50 of the urine collection wall, and connects the exhaust passage 47 and the odor collecting space 71. The odor collecting space 71 is located above the urine collecting portion 70 sandwiched between the front road wall 56 of the rear distribution passage 45 and the urine collection wall upper portion 50 above it and the rear distribution wall 52 of the front distribution passage 52. It is a space part.

As shown in FIG. 5, the exhaust port 90 is provided slightly below the middle position of the exhaust passage forming portion of the rear wall 46. In FIG. 5, 100 is a wastewater discharge port, and 1 is
Reference numeral 01 is a bolt insertion hole for fixing the urinal 40 to the wall surface.

In order to remove the odor generated in the urine collecting part 70 when the urinal 40 is used, an exhaust device is connected to the exhaust port 90 and operated. The odor naturally rises to reach the odor collecting space 71, is sucked into the exhaust passage 47 from the intake port 48, and is then discharged from the exhaust port 7 to the outside.

The embodiments of the present invention are not limited to the above. For example, the height position of the exhaust port can be freely selected within a range that does not cause mutual interference with the back hanger portion 80.
Further, the present invention can be applied not only to wall-mounted urinals, but also to floor-mounted urinals.

[Effects of the Invention] As is clear from the above description, the present invention has a number of excellent effects as listed below.

The exhaust port can be provided below the back wall. As a result, when the wall-mounted urinal is attached to the wall surface, the work of connecting the exhaust device and the exhaust port can be performed in a work space much wider than before (see FIG. 11). Therefore, the workability is remarkably improved, so that the labor and the construction time can be shortened.

Since the distance between the back hanger portion provided on the rear wall and the exhaust port can be increased, there is no risk of an accident such that the gasket is damaged by being sandwiched between the rear wall and the wall surface. Therefore, a reliable connection between the exhaust port and the exhaust device can be obtained.

It is easy to change the shape of the intake port to a desired shape. That is, in addition to the illustrated circle, an ellipse, a rectangle, etc.
It can be selected appropriately. Therefore, if the intake port is formed as a laterally long hole, the height dimension can be made extremely small with the same opening area. In the conventional urinal, since the exhaust port is limited to a circular shape, the height dimension of the urinal itself is increased by providing the exhaust passage. On the other hand, in the present invention, since the exhaust port is provided in the lower portion and the height of the intake port can be reduced, it is possible to avoid the height of the urinal from increasing.

Furthermore, if a horizontally long intake port is adopted, the area where odors can be sucked in at one time can be expanded horizontally, so much higher deodorization efficiency than before can be obtained.

Since the exhaust port can be provided in the lower part apart from the water supply port, mutual interference between the water supply pipe and the exhaust pipe can be eliminated.

Conventionally, both the exhaust port and the water supply port are provided close to each other in the upper part of the urinal, which makes it difficult to connect the respective conduits and the workability is poor.

However, according to the present invention, the piping work is very easy and the workability is extremely good. Therefore, the present invention exerts a particularly excellent effect when a large number of plumbing works need to be performed, such as when constructing a system toilet.
