Technical Field
[0001] This utility model relates to the field of sanitary ware, and in particular to a free-flow toilet with adjustable hole spacing. Background Technology
[0002] The hole spacing refers to the distance from the center of the drain opening on the floor connecting the toilet to the wall in a floor-mounted drain system. Different buildings have different hole spacing requirements, such as 100mm, 150mm, 200mm, 250mm, and 300mm. Traditional toilets have their drain outlet located at the bottom, requiring alignment with the drain pipe during installation. Therefore, it's essential to measure the building's pre-installed hole spacing before purchasing a toilet. Otherwise, if the hole spacing is smaller than the building's pre-installed spacing, there will be a large gap between the back of the toilet and the wall. If the hole spacing is larger than the building's pre-installed spacing, the toilet may not be able to be installed at all. For users who want to replace their old toilets, it's impossible to measure the hole spacing without first removing the old one, making it impossible to purchase a toilet with a matching hole spacing. Removing the old toilet before buying a new one disrupts daily life before installation. Traditional toilets cannot accommodate various hole spacings, making them inconvenient to use. Furthermore, conventional floor-mounted toilets, because their drain outlet is in contact with the floor, cannot be connected to a separate water pipe for wall-mounted drainage, limiting their usability and further complicating their use. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a free-flow toilet with adjustable hole spacing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a free-draining toilet with adjustable hole spacing, comprising a toilet body, wherein a drain pipe integrally formed with the toilet body is provided in the middle of the inner side of the toilet body, the drain outlet of the drain pipe faces the back of the toilet body, a back opening is provided on the back of the toilet body, a bottom opening is provided at the bottom of the toilet body, the back of the bottom opening and the bottom of the back opening are connected to form an integral unit, and a water outlet pipe for connecting to a sewer pipe is installed on the drain outlet.
[0005] Furthermore, the water outlet pipe is either a wall-mounted pipe or a floor-mounted pipe.
[0006] Furthermore, the ground drain pipe includes a connecting part, a turning part, and a ground drain part.
[0007] Furthermore, the connecting part is horizontally arranged, with its front end connected to the sewage outlet, and the turning part is a "U" shape arranged by rotating 90°, with its upper end connected to the connecting part and its lower end connected to the ground drain part.
[0008] Furthermore, the ground discharge section includes a horizontally arranged adjustable pipe and a longitudinally arranged discharge pipe, wherein the adjustable pipe is connected to the lower end of the steering section.
[0009] In one embodiment, the adjustable pitch fitting is inserted into the lower opening of the steering section, and the adjustable pitch fitting is connected to the lower opening of the steering section by PVC glue.
[0010] Furthermore, the length of the bottom opening of the toilet body is greater than the length of the floor drain pipe, and the height of the back opening of the toilet body is greater than the height of the floor drain pipe.
[0011] The beneficial effects of this utility model are as follows: 1. This utility model toilet has a back opening on the back of the toilet body and a bottom opening integrated with the back opening at the bottom of the toilet body, with the drain outlet of the drain pipe facing the back of the toilet body. This allows the drain outlet to be freely connected to the wall drain or floor drain via a water outlet pipe, thus making this utility model applicable to both wall and floor drain scenarios and possessing excellent versatility; 2. When using floor drain, first install the floor drain pipe, and cut the adjusting pipe fitting according to the pre-drilled hole spacing in the toilet to obtain a suitable floor drain pipe. After the floor drain pipe is installed, place the toilet on top. The toilet body is pushed towards the floor drain pipe. Because the bottom opening of the toilet body is connected to the bottom of the back opening, the bottom opening and the back opening are integrated. The toilet body will not block the floor drain pipe, allowing the drain outlet to be smoothly connected to the floor drain pipe to complete the installation of the toilet. The hole spacing after the toilet is installed is determined by the floor drain pipe, not by the toilet body. This allows the toilet body and floor drain pipe to adapt to different building reserved hole spacing scenarios, making it more versatile. 3. Since the drain outlet faces the back of the toilet body, when using wall drain, a horizontally set wall drain pipe can be used to connect the drain outlet and the drain pipe on the wall, further improving the versatility of the toilet body.

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] Example 1: A free-flow toilet with adjustable hole spacing includes a toilet body 1. A drain pipe 4, integrally formed with the toilet body 1, is located in the center of the inner side of the toilet body 1. The drain outlet 41 of the drain pipe 4 faces the back of the toilet body 1. A floor drain pipe 5 for connecting to a sewer pipe is installed on the drain outlet 41. When the toilet uses floor draining, the pre-installed sewer pipe is located on the ground. A back opening 2 is provided on the back of the toilet body 1, and a bottom opening 3 is provided at the bottom of the toilet body 1. The back of the bottom opening 3 communicates with the bottom of the back opening 2, allowing the bottom opening... 3 and the back opening 1 are integrated. During installation, first install the floor drain pipe 5 that matches the reserved hole spacing of the toilet on the drain opening, and then push the toilet body 1 towards the floor drain pipe 5. Since the bottom opening 3 and the back opening 2 are integrated, the floor drain pipe 5 will not be blocked when pushing the toilet body 1. Connect the drain outlet 41 to the upper port of the floor drain pipe 5 to complete the installation. After installation, the hole spacing of the toilet is determined by the floor drain pipe 5 and not by the toilet body 1. The toilet body 1 of this application, combined with the floor drain pipe 5, can be adapted to toilets with different hole spacing requirements, avoiding the purchase of toilets with the wrong hole spacing, which would result in installation failure. It is convenient to use and highly versatile.
[0019] Furthermore, the ground drain pipe 5 includes a connecting part 51, a turning part 52, and a ground drain part 53. The connecting part 51 is horizontally arranged, and its front end is connected to the sewage outlet 41. The turning part 52 is a "U" shape that is rotated 90°, with its upper end connected to the connecting part 51 and its lower end connected to the ground drain part 53.
[0020] Furthermore, the ground discharge section 53 includes a horizontally arranged adjustable pipe 531 and a longitudinally arranged discharge pipe 532, wherein the adjustable pipe 531 is connected to the lower end of the turning section 52.
[0021] In this embodiment, the floor drain section 53 is separately arranged from the connecting section 51 and the turning section 52. First, the hole spacing reserved for the toilet is measured, and then a portion of the adjusting pipe 531 is cut off according to the hole spacing, so that after the floor drain section 53 is inserted into the turning section 52, the lateral distance from the central axis of the drain pipe 532 to the rear side of the turning section 52 is equal to the hole spacing reserved for the toilet. PVC glue is applied to the outer surface of the cut adjusting pipe 531 and the inner surface of the lower port of the turning section 52. Then, the adjusting pipe 531 is inserted into the lower port of the turning section 52, thereby obtaining a floor drain pipe 5 that matches the hole spacing reserved for the toilet. When purchasing a new toilet, it is not necessary to remove the old toilet to measure the hole spacing first. The matching floor drain pipe 5 can be made on-site according to the hole spacing reserved for the toilet when installing the new toilet, which is more convenient to use.
[0022] Furthermore, the length of the bottom opening 3 of the toilet body 1 is greater than the length of the floor drain pipe 5, and the height of the back opening 2 degrees of the toilet body 1 is higher than the height of the floor drain pipe, to prevent the toilet body 1 from blocking the floor drain pipe 5.
[0023] Example 2: Based on Example 1, a variation is made. When the toilet uses wall-mounted sewage discharge, the water outlet pipe is a wall-mounted pipe 6. The wall-mounted pipe 6 is horizontally connected to the sewage outlet 41 and the sewer outlet set on the wall. The toilet body can be used for both floor-mounted and wall-mounted sewage discharge, and has better versatility.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
