2. Description of the Related Art Conventionally, as a wall draining urinal of this type, for example, Japanese Patent Laid-Open No. 11-81427 discloses a bowl having a drainage tube having a drainage port in the center and a recess formed outside the drainage tube. , A removable trap configured by a removable sana that is mounted in the recess while covering the drain, and discharges the waste that has passed through the removable trap on the downstream side of the removable trap to a drain pipe disposed on the wall surface. A wall drain urinal with a drain is described. This wall drain urinal prevents foreign matter from entering the drain because even if a relatively small one falls into the bowl, the foreign matter does not get over the drain and stops at the recess outside the drain. it can. In addition, since the removable sana can be removed, it is possible to easily clean the drain tube, the concave portion on the outside of the drain tube and the removable sana. On the other hand, Japanese Unexamined Patent Application Publication No. 2000-303542 includes a bowl having a drainage port at the bottom and a drainage channel in which a trap is formed by connecting the drainage port and a drainage pipe provided on a wall surface in a substantially U shape. Wall drain urinals are listed. Although not shown here, generally, a drain plate at the bottom of the bowl is provided with a mesh plate made of ceramics in a mesh shape. By attaching this eye plate, it is possible to prevent large foreign matter from entering the drainage channel. In addition, since the drainage channel itself forms a trap in this wall draining urinal, if the height of the drainage port at the bottom of the bowl is located above the lower end of the drainage pipe installed on the wall surface, dirty water will not be collected. Since it does not collect at the bottom of the bowl, there is a large degree of freedom in designing the bowl height.

[0003]

However, JP-A-11-
In the wall drain urinal seen in 81427, when the lower end of the drain pipe disposed on the wall surface is located above the recess on the outside of the drain cylinder, a trap is formed in the drain as well as the detachable trap. It becomes a so-called double trap. In the double trap state, the drain pipe sandwiched between the two traps will be blocked, and there will be no escape place for the air that flows in along with the drainage from the equipment, which will adversely affect the water seal of the drain trap and the flow of sewage. become. In order to avoid the state of the double trap, it is necessary to position the lower end of the drainage pipe below the recess, and the degree of freedom in designing the bowl height is small. On the other hand, in the wall drain urinal seen in Japanese Unexamined Patent Publication No. 2000-303542, since the perforated plate is made of ceramics, even a relatively large foreign substance having a large mesh interval passes through the perforated plate and enters the drainage channel to trap the drainage channel Could clog
Further, since the trap is formed by bending the drainage channel into a substantially U-shape at an acute angle, the cleanability of the drainage channel was poor. The present invention has been made to solve the above problems, and an object of the present invention is to prevent the entry of a relatively large foreign substance into the drainage channel while ensuring the degree of freedom in designing the bowl height and to clean the bowl. To provide a wall drain urinal with good performance.

A wall drain urinal with a drainage channel having a trap formed in a shape. By doing so, the height of the drainage port can be located near the lower end of the drainage pipe arranged on the wall surface, so that the degree of freedom in designing the bowl height is secured, and relatively large foreign matter is drained. Since it does not get over the cylinder and stops at the recess on the outside of the drainage cylinder, it is possible to prevent the entry into the drainage channel. Further, by removing the cover, the drain pipe, the recess on the outside of the drain pipe, and the cover can be easily cleaned.

As a preferred aspect of the present invention, the invention according to claim 2 is characterized in that, in the drainage channel, a path extending from the drainage port to the drainage pipe is formed by an obtuse bend. By doing so, since a cleaning tool such as a brush can be easily inserted into the drainage channel, the cleanability of the drainage channel can be improved.

As a preferred embodiment of the present invention, the invention according to claim 3 is characterized in that the drainage channel has a path extending from the drainage port to the reservoir part of the trap inclined inward. By doing so, it becomes easier for the cleaner to insert a cleaning tool such as a brush into the drain port, and thus the cleanability of the drainage channel is improved.

As a preferred embodiment of the present invention, the invention according to claim 4 is characterized in that the drainage channel is formed integrally with the bowl. By doing so, there is no joint surface between the drainage channel and the bowl, so that dirt does not enter the joint surface and the cleanability is further improved.
