[0040] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] like Figure 1-7 As shown, the utility model is a wall drainage system for renovating old houses, including a post-fabricated wall 1, a drainage pipe 2, a plurality of connecting pipes 3, sanitary ware 4 and a tile floor 5. The wall drainage system, as the name implies, is a drainage system that mainly relies on the post-fabricated wall 1, and is used for drainage renovation of existing houses, which include original walls 6, original drainage pipes 7 and original floors 8.

[0042] The post-fabricated wall 1 is used to carry other components. The post-fabricated wall 1 is fixed against the original wall 6 and can be a solid wall or a hollow frame structure.

[0043] The drain pipe 2 is the main sewage pipe in the room, and the connecting pipe 3 is the branch sewage pipe in the room. The drain pipe 2 is fixedly arranged in the rear wall 1 and is sealed and connected with the original sewage pipe 7; the connecting pipe 3 is passed through and fixed in the rear wall 1, one end of which is sealed and connected with the drain pipe 2, and the other end is located on the side of the rear wall 1 away from the original wall 6, and is used to be connected with the sanitary ware 4.

[0044] The sanitary ware 4 is arranged on the post-made wall 1 or above the original ground 8. The sanitary ware 4 is sealed and connected with the connecting pipe 3, and the sewage inside it flows into the original sewage pipe 7 along the connecting pipe 3 and the drain pipe 2; since the drain pipe 2 and the connecting pipe 3 between the sanitary ware 4 and the original sewage pipe 7 are both attached to the post-made wall 1, there is no need to modify the original building structure of the old house, so that the wall drainage system can be adapted to old houses or old houses whose original building structures cannot be changed, thereby improving the adaptability of old house renovation.

[0045] The tile floor 5 is a floor reconstructed for the old house. The tile floor 5 is laid on the original floor 8 and is formed by a plurality of sealed tiles. By setting the tile floor 5, the aesthetics of the old house floor can be improved without the need to construct the original floor 8.

[0046] like Figure 1 As shown, the sanitary ware 4 includes a floor drain 41 and a toilet 42. The floor drain 41 is fixedly set on the tile floor 5 and is connected with the drain pipe 2 through the connecting pipe 3. The top side of the floor drain 41 is flush with the top side of the tile floor 5. By setting the tile floor 5, the floor of the original house can be lifted and the floor drain 41 can be embedded in the tile floor 5. The floor drain 41 can be installed without constructing the original floor 8 to collect the accumulated water on the surface of the tile floor 5.

[0047] The toilet 42 is fixedly mounted on the rear wall 1 and is connected to the drainage pipe 2 via the connecting pipe 3 . The toilet 42 is also not connected to the original ground 8 , so there is no need to construct the original ground 8 .

[0048] like Figure 3 As shown, three connecting pipes 3 are provided, two of which are sealed and connected between the drain pipe 2 and the floor drain 41 and the toilet 42, and one end of the other connecting pipe 3 is sealed and connected to the drain pipe 2, and the other end is used to connect to the wash basin.

[0049] like Figure 2 and Figure 3As shown, the drain pipe 2 includes a first tube body 21, a second tube body 22, two tees 23, a check valve 24 and an inspection cover 25, wherein one tee 23, the second tube body 22, another tee 23, the first tube body 21 and the original sewage pipe 7 are sealed and connected in sequence; the connecting pipe 3 connected to the floor drain 41 is sealed and connected to the tee 23 between the first tube body 21 and the second tube body 22, and the other two connecting pipes 3 are sealed and connected to another tee 23 to realize the connection between each sanitary ware 4 and the drain pipe 2.

[0050] like Figure 5 As shown, the tee 23 includes a tee body 231 and a fixing plate 232, wherein the tee body 231 is provided with three interconnected interfaces 201; a fixing plate 232 is fixedly provided in one of the interfaces 201 of each tee body 231, and a connecting hole 202 is opened on the upper part of the fixing plate 232, and the connecting pipe 3 connected to the floor drain 41 and the connecting pipe 3 for communicating with the wash basin are sealed and fixed in the two connecting holes 202 respectively; since the three connecting pipes 3 are connected in parallel to the drain pipe 2, it is easy for sewage to communicate with each other, and by inserting the connecting pipe 3 connected to the floor drain 41 and the connecting pipe 3 for communicating with the wash basin into the upper part of the interface 201, it can be prevented that the sewage discharged from the toilet 42 flows back into the other two connecting pipes 3; similarly, as Figure 4 As shown, the end of the connecting pipe 3 connected to the connecting hole 202 away from the sanitary ware 4 is spaced apart from the side of the fixing plate 232 away from the sanitary ware 4, that is, the connecting pipe 3 is inserted into the fixing plate 232 and extends a distance from one end, thereby preventing the sewage in the drain pipe 2 from flowing into the corresponding connecting pipe 3.

[0051] The check valve 24 is used to prevent the sewage in the original sewage pipe 7 from flowing into the drain pipe 2, and to prevent the insects and rodents in the original sewage pipe 7 from entering the drain pipe 2, which has a good odor-blocking and isolating effect. Figure 3 As shown, the check valve 24 is arranged in communication with the first pipe body 21 .

[0052] The inspection cover 25 is used for maintaining the inside of the check valve 24. An inspection port 203 is provided on the peripheral side of the check valve 24. The inspection cover 25 is sealed and fixed in the inspection port 203 to block it. When the check valve 24 needs to be maintained, the inspection cover 25 can be removed from the check valve 24.

[0053] However, since the drain pipe 2 is located in the rear wall 1, in order to facilitate the disassembly and assembly of the inspection cover 25, as shown in FIG. Figure 1 As shown, a maintenance hole 101 is opened on the side of the post-fabricated wall 1 away from the original wall 6, and the maintenance port 203 is connected to the maintenance hole 101, and the inner diameter of the maintenance hole 101 is larger than the inner diameter of the maintenance port 203; when the check valve 24 needs to be inspected, the inspection cover 25 can be removed from the inspection hole 101.

[0054] like Figure 6 As shown, the floor drain 41 is preferably a side-discharge floor drain, having a water inlet 401 on the top side and a water outlet 402 on the peripheral side, and the water outlet 402 is sealed and connected to the connecting pipe 3. By using a side-discharge floor drain, the overall height of the floor drain 41 can be reduced, thereby reducing the laying thickness of the tile floor 5.

[0055] like Figure 7 As shown, the toilet 42 is a wall-mounted toilet with a sewage outlet 403 on its peripheral side, and the sewage outlet 403 is sealed and connected to the connecting pipe 3. It also does not need to occupy much height space, which is beneficial to the space utilization in the house.

[0056] The construction method of a wall drainage system for old house reconstruction of the utility model is as follows:

[0057] like Figure 2 As shown, first install the drainage pipe 2 in the old house and connect the drainage pipe 2 with the original sewage pipe 7, and then Figure 1 As shown, the rear wall 1 is constructed, the toilet 42 is installed on the rear wall 1 and connected with the corresponding connecting pipe 3, the floor drain 41 is connected with the corresponding connecting pipe 3, and finally the tile floor 5 is laid so that the upper surface of the tile floor 5 is flush with the top side of the floor drain 41.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
