Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage socket in which a drainage port of a sitting toilet is inserted and connected from above, which is connected to a drainage pipe buried in a floor of a toilet.

[0002]

2. Description of the Related Art In a conventional toilet, as shown in FIG. 3, a stool toilet 21 is installed in the toilet, and a toilet bowl etc. in the toilet is separately installed apart from the stool toilet 21. When the hand washing device 25 and the like are separately installed, a drain pipe 27 such as the hand washing device 25 is provided on the building side (not shown) separately from the drain pipe 28 of the sitting toilet 21, or the drain pipe 27 of the hand washing device 25 is installed. A drainage pipe was inserted on the floor from the opening 23 above the floor of the skirt 22 of the toilet bowl to join the toilet drainage connection 26 in the toilet skirt.

[0003]

However, in the conventional toilet, when the drain pipe such as the hand-washing device is connected to the drain pipe on the side of the building which is specially provided in addition to the drain pipe of the toilet bowl, the drain is drained into the toilet. There is a problem that it is necessary to install two pipes and it takes time and effort for the construction.

When connecting a drainage pipe of a sanitary equipment such as a hand-washing device to a drainage connecting portion from a stool toilet skirt portion, as shown in Japanese Patent Laid-Open No. 2000-248603, drainage connection is made inside the stool toilet skirt portion. Although it is structured to be connected to the toilet part, it is difficult to clean the area around the sitting toilet bowl because it is necessary to place a drain pipe such as a hand-washing device on the floor, and the appearance is not good. Further, it is necessary to preliminarily form an opening for a drain pipe such as a hand basin on the floor surface portion of the stool toilet skirt, which causes a problem that productivity during molding of the stool toilet deteriorates.

Further, in the case of a siphon-type toilet bowl that discharges dirt by utilizing the negative pressure generated by the siphon action, a separate drain pipe 31 such as a hand-washing device as shown in FIG. 4 is used to induce the siphon action. When they are merged upstream of 9, the negative pressure also acts on the side of the separate drain pipe 31, and as a result, the force of drawing in the dirt due to the siphon action is dispersed and the cleaning ability is deteriorated.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a drainage pipe from other sanitary equipment such as a handwasher without separately laying it on the building side.
It is an object of the present invention to provide a drain socket that prevents deterioration of cleaning performance even in a siphon stool, eliminates disposition of a drain pipe such as a hand basin on the floor, and facilitates cleaning around the stool.

[0007]

In order to solve the above problems, the present invention according to claim 1 is such that the drainage port of the sitting toilet is inserted into the drainage pipe buried in the floor of the toilet from above. A drainage socket to be connected, a fixing part for fixing the sitting toilet at a position above the toilet floor surface, and a hand-washing device provided at the fixing portion and arranged at a position apart from the sitting toilet , A washbasin, a connection portion for connecting drainage pipes from other sanitary equipment such as waste distribution, and a connection path for connecting the drainage pipes connected to the connection portion and the drainage flow path of the drainage socket I was prepared. By doing so, it is possible to connect to the drain pipe of sanitary equipment such as a handwasher above the floor of the toilet where the drain socket is installed, so eliminating the placement of the drain pipe of the handwasher on the floor surface. be able to. Also, because the hole for fixing the toilet bowl and the opening for the drain pipe such as the toilet bowl can be used together, it is necessary to pre-form the opening for the drain pipe such as the toilet bowl in the skirt portion of the sitting toilet bowl. Disappeared
It is possible to eliminate the deterioration of the productivity at the time of molding a stool.

According to a second aspect of the present invention, there is provided a drain socket in which a drain port of a siphon-type sitting toilet is inserted and connected from above to a drain pipe buried in a toilet floor surface. The siphon of the siphon-type sitting toilet is provided. A throttling part provided in the drainage flow path to induce the action, a fixing part for fixing the siphon-type sitting toilet at a position above the toilet floor surface, and the siphon-type A connection part for connecting drain pipes from other sanitary equipment equipment such as a hand basin, a wash basin, and a waste distribution facility arranged at a position apart from the stool toilet,
The drainage pipe connected to the connection portion and a drainage passage that connects the drainage passage of the drainage socket are provided, and the communication passage joins the drainage passage downstream of the throttle portion. By doing so, there is no problem that the ability to draw in the waste due to the siphon action is not dispersed and the cleaning capacity is not reduced, and the drain pipe of sanitary equipment such as a hand wash is above the toilet floor where the drain socket is installed. Since it can be connected, it is possible to eliminate the arrangement of the drain pipe such as a handwasher on the floor surface. Also, because the hole for fixing the toilet bowl and the opening for the drain pipe such as the toilet bowl can be used together, it is necessary to pre-form the opening for the drain pipe such as the toilet bowl in the skirt portion of the sitting toilet bowl. Therefore, it is possible to eliminate the deterioration of the productivity at the time of forming a sitting toilet bowl.

In a preferred aspect of the present invention, the fixing portion also serves as the connecting portion. As a combined configuration, as shown in claim 5, the communication path is integrally formed with the drain socket, and an end portion of the communication path is arranged so as to project upward from a through hole formed in the seat bowl. Set up
The drain pipe is connected to the projecting end portion and the fixing member for fixing the stool toilet is engaged with the projecting end portion to fix the stool toilet.
By doing so, it is not necessary to have a special structure in the stool to connect and connect the drainage pipe to the drainage socket.

In a preferred aspect of the present invention, the connecting passage is formed integrally with the drain socket. By doing so, the cost is lower than when the connecting path is formed of a separate member and assembled to the drain socket.
