Description

Technical Field

[0001] The invention belongs to the technical field of toilets, and in particular relates to a toilet. Background Art

[0002] Wall-mounted toilets are widely popular because their bottoms do not touch the ground, making them easy to clean, and they are small in size and save more space.

[0003] like Figure 1 As shown, in order to form a siphon phenomenon and allow waste to be discharged smoothly, the existing wall-mounted toilet needs to bend the sewage pipe 2 of the wall-mounted toilet for many times inside the ceramic body 1, so that the total length and total height of the wall-mounted toilet need to be increased to ensure the performance of the toilet, which makes the wall-mounted toilet lose its space-saving advantage; and, since the sewage pipe needs to be bent many times, the sewage travels a long distance in the sewage pipe, which makes the sewage discharge effect worse.

[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0052] Example 1

[0053] In this embodiment, a toilet is disclosed, such as Figure 2 and Figure 3 As shown, the toilet includes a ceramic body 1 and a sewage pipe 2.

[0054] Specifically, one end of the sewage pipe 2 is connected to the ceramic body 1, and the other end of the sewage pipe 2 extends from the rear end of the ceramic body 1 and can be connected to the sewage pipe, so that the dirt in the ceramic body 1 is discharged into the sewage pipe through the sewage pipe 2. The rear end of the ceramic body refers to the end of the ceramic body used for fixed connection with the wall.

[0055] Furthermore, the sewage pipe 2 includes a climbing section 21 and a descending section 23 which are fixedly connected; wherein the climbing section 21 is a gradually ascending pipe section, and the descending section 23 is a pipe section arranged in the up-down direction. The descending section 23 of this embodiment adopts an up-down straight section structure. The climbing section 21 is entirely located inside the ceramic body 1 and is fixedly connected to the sewage inlet 11 of the ceramic body 1. The descending section 23 is entirely located outside the ceramic body 1. The climbing section 21 and the descending section 23 constitute a siphon structure. The siphon structure is simpler. Under the premise of ensuring the siphon effect, the sewage has a shorter travel distance in the siphon structure and flows more smoothly. Of course, in other embodiments, such as Figure 4 As shown, part of the climbing section 21 is located inside the ceramic body 1, and part of the climbing section 21 is located outside the ceramic body 1, which is also within the protection scope of the present invention.

[0056] Since the toilet needs to be connected to the wall, when the toilet is installed on the wall, at least the entire descending section 23 will be buried in the wall and connected to the sewage pipe in the wall. A siphon structure is formed by the climbing section 21 and the descending section 23, that is, the sewage plastic pipe buried in the wall when the existing wall-mounted toilet is installed on the wall forms a part of the siphon structure (siphon pipe) of the toilet in this embodiment; wherein, the sewage plastic pipe of the existing wall-mounted toilet is used to connect the siphon pipe and the sewage pipe. In this way, the ceramic body 1 of this embodiment only needs to accommodate part of the siphon structure (climbing section 21), and the other part of the siphon structure (descending section 23) is buried in the wall, so that the volume of the ceramic body 1 can be designed to be smaller, and its length a can be controlled within 500mm~620mm, and its minimum height can be reduced to 310mm, which can save 25% of the installation space and reduce the production cost of the ceramic body 1 by 20%; and, after the ceramic body 1 is installed on the wall, the upper end face of the ceramic body 1 is 400mm from the ground, and the lower end face of the ceramic body 1 is more than 80mm from the ground, thereby facilitating the cleaning of the bottom of the toilet. In addition, the design of the above-mentioned siphon structure of this embodiment, compared with the sewage discharge stroke of the existing wall-mounted toilet, includes a siphon pipe arranged in the ceramic body and a sewage discharge plastic pipe buried in the wall, so that the sewage discharge stroke distance from the sewage inlet of the ceramic body to the sewage pipe is shorter. Compared with the sewage discharge stroke of the existing wall-mounted toilet of 1100mm, the sewage discharge stroke of the toilet in this embodiment is 650mm, the sewage discharge stroke is shortened by 40%, and the sewage discharge effect is better.

[0057] In summary, in the toilet of this embodiment, the sewage pipe is designed to be a segmented structure, and part of the sewage pipe extends from the rear end of the ceramic body, so that at least part of the climbing section located inside the ceramic body and the descending section located outside the ceramic body form a siphon structure, thereby making the volume of the ceramic body smaller, reducing the production cost of the toilet, saving more space for installation, and having a better siphon effect, a shorter sewage discharge distance, and cleaner sewage discharge.

[0058] In this embodiment, Figure 3 As shown, the sewage pipe 2 also includes a horizontal section 22; wherein the horizontal section is a pipe section arranged along the horizontal direction.

[0059] Specifically, the horizontal section 22 is connected between the climbing section 21 and the descending section 23, and part of the horizontal section 22 extends from the ceramic body 1, that is, part of the horizontal section 22 extends from the ceramic body 1, and part of the horizontal section 22 is located in the ceramic body 1. A siphon structure is formed by the climbing section 21, the horizontal section 22 and the descending section 23. The siphon structure is similar to a "J" shape, and the overall structure is simpler. The horizontal distance between the climbing section 21 and the descending section 23 can be controlled by selecting the length of the horizontal section 22, so that when the toilet is fixed on the wall, the descending section 23 can be completely buried in the wall. Of course, all the horizontal sections can also extend from the ceramic body.

[0060] In addition, if Figure 3 As shown, the ceramic body 1 and the sewage pipe 2 adopt an integrated structure, and the climbing section 21, the horizontal section 22 and the descending section 23 in the sewage pipe 2 also adopt an integrated structure. This makes the structure of the toilet simpler.

[0061] Furthermore, the vertical distance d between the upper end of the sewage inlet 11 and the upper end surface of the ceramic body 1 is 200 mm to 360 mm, the vertical distance between the lower end of the descending section 23 and the bottom of the horizontal section 22 is not less than 110 mm, and the diameter of the descending section 23 below the horizontal line where the upper end of the sewage inlet 11 is located is 40 mm to 60 mm; through the above-mentioned size design, as Fig.12 As shown, when the vertical distance f between the bottom of the pot surface of the ceramic body 1 and the upper end surface of the ceramic body 1 is 285mm~330mm, the vertical distance g between the water seal liquid surface 5 formed by the ceramic body 1 and the upper end surface of the ceramic body 1 is 170mm~215mm, thereby making the depth of the water seal liquid surface 5 deeper and the water seal effect better; at the same time, the siphon effect formed by the sewage pipe 2 can also be better. When flushing, the negative pressure formed in the sewage pipe 2 is increased by 85% compared with the existing solution, and the negative pressure value can reach more than 1500pa, and the flushing effect is improved by more than 1 times.

[0062] In this embodiment, the diameter of the climbing section 21 is 40 mm to 70 mm, and the diameters of the horizontal section 22 and the descending section 23 are both 40 mm to 60 mm, which not only meets the sewage discharge requirements, but also further improves the siphon effect. Of course, the size of the sewage pipe can also be selected from other solutions such as the diameter of the climbing section is 40 mm to 70 mm and / or the diameter of the horizontal section is 40 mm to 60 mm and / or the diameter of the descending section is 40 mm to 60 mm.

[0063] In addition, the vertical distance c between the upper end of the sewage inlet 11 and the bottom of the horizontal section 22 is 50mm~65mm, which can effectively increase the siphon effect; in addition, the length b of the sewage pipe 2 extending out of the ceramic body 1 is 100mm~260mm, and the vertical distance between the center of the wall hanging hole of the ceramic body 1 and the center of the sewage inlet 11 is 55mm~100mm, which facilitates the installation of the ceramic body 1 on the wall and improves the stability of the installation of the ceramic body 1.

[0064] Furthermore, the climbing section 21 adopts a variable diameter design, for example, the diameter of the climbing section 21 decreases in sequence from the sewage inlet 11 to the horizontal section 22 (descending section 23), or the inlet diameter of the climbing section 21 is large, the outlet diameter is small, and the diameter of the middle section of the climbing section 21 remains unchanged, etc.; this can increase the siphon effect of the sewage pipe 2. Among them, the inclination of the climbing section 21 is 40° to 55°, and preferably, the inclination of the climbing section 21 is 48°. The horizontal section and the descending section in this embodiment can adopt a uniform diameter structure or a variable diameter structure, which is limited here.

[0065] Example 2

[0066] This embodiment is different from Embodiment 1 in that Figure 5 and Figure 6 As shown, a water blocking structure 231 is provided on the descending section 23 .

[0067] In this way, when the sewage in the sewage pipe 2 moves to the water blocking structure 231, the flow of the sewage is blocked, so that the flow speed of the sewage is slowed down, which is convenient for forming a siphon phenomenon. Compared with the siphon generation time of the existing wall-mounted toilet of 2.5 seconds, the siphon generation time of the toilet in this embodiment is less than 1.5 seconds, and the siphon generation is faster, which can effectively improve the sewage discharge effect. Furthermore, a water blocking platform is formed in the water blocking structure 231, that is, a water blocking platform is formed in the descending section 23, and the flow of sewage is blocked by the water blocking platform.

[0068] The water-blocking structure 231 in this embodiment is a bending structure, and the bending structure is an arc-shaped structure bent toward the rear of the ceramic body 1, so that the sewage in the water-blocking structure 231 flows more smoothly; of course, the bending structure can also be an arc-shaped structure bent toward the front, left or right side of the ceramic body; or, the bending structure is a right-angle structure bent toward the rear of the ceramic body, all of which are within the protection scope of the present invention.

[0069] In other embodiments, Figures 7 to 9 As shown, the water blocking structure 231 may also be a ramp structure, an oblique bending structure or a variable diameter structure, or may be composed of two or three of the variable diameter structure, the bending structure and the ramp structure.

[0070] In this embodiment, the water blocking structure 231 is arranged at the upper end of the descending section 23 and connected to the horizontal section 22. Of course, the water blocking structure can also be arranged at the middle position or other positions of the descending section.

[0071] Furthermore, the vertical distance e between the bottom of the horizontal section 22 and the lower end of the water blocking structure 231 is 50 mm to 300 mm, so that the siphon effect in the sewage pipe 2 is better.

[0072] In addition, a mounting section 232 is formed at the lower end of the descending section 23. The mounting section 232 is a linear structure and is used to connect to the sewage pipe, thereby facilitating installation. The outer diameter of the mounting section may be consistent with the outer diameter of the sewage pipe.

[0073] Example 3

[0074] The difference between this embodiment and embodiment 2 is that Figures 10 to 12 As shown, the climbing section 21 and the ceramic body 1 adopt an integrated structure, and the climbing section 21 and the horizontal section 22 adopt a split structure, which is convenient for the production, storage, transportation and installation of the ceramic body 1, and the horizontal section 22 and the descending section 23 can adopt ordinary sewage plastic pipes, thereby saving the production cost of the toilet.

[0075] In addition, a straight installation section is extended from one end where the climbing section 21 is connected to the horizontal section 22. The straight installation section is located in the ceramic body 1 and can be sleeved with the horizontal section 22, so as to facilitate the assembly of the climbing section 21 and the horizontal section 22. In addition, a sealing member 6 is provided between the climbing section 21 and the horizontal section 22 to achieve the sealing between the climbing section 21 and the horizontal section 22 to prevent water leakage. The sealing member 6 can be a sealing rubber. Of course, the climbing section and the horizontal section are not limited to being connected by sleeve connection, but can also be connected by bonding or bolting.

[0076] Furthermore, the horizontal section 22 and the descending section 23 adopt a split structure, which can further improve the convenience of toilet production, storage and transportation.

[0077] Of course, the horizontal section and the descending section may also adopt an integrated structure; or, the climbing section and the horizontal section may adopt an integrated structure, and the horizontal section and the descending section may adopt a separate structure, which is also within the protection scope of the present invention.

[0078] When the toilet in this embodiment is mounted on the wall, Fig.14 As shown, the ceramic body 1 is first fixed on the toilet bracket 3, and the support of the ceramic body 1 is achieved by the toilet bracket 3. The toilet bracket 3 is buried in the wall. The ceramic water inlet 14 of the ceramic body 1 is connected to the water tank 4 on the toilet bracket 3. The sewage pipe 2 passes through the lower part of the toilet bracket 3 and is connected to the sewage pipe.

[0079] The flushing path of the toilet is: Fig.13 As shown, the water in the water tank 4 enters the ceramic water channel 15 in the ceramic body 1 through the ceramic water inlet 14, and part of the water in the ceramic water channel 15 flows out through the wash ring water inlet hole 16 and the wash ring water outlet hole 17 in turn to achieve the toilet ring washing, and part of the water in the ceramic water channel 15 is ejected through the injection hole 18 to achieve the main flushing of the toilet, and the generated sewage is discharged from the sewage inlet 11.

[0080] Example 4

[0081] The difference between this embodiment and embodiment 1 and embodiment 2 is that Figures 15 to 19 As shown, the climbing section 21 and the ceramic body 1 adopt a separate structure, which makes the structure of the ceramic body 1 simpler and easier to produce; and the climbing section 21, the horizontal section 22 and the descending section 23 can use ordinary sewage plastic pipes, thereby saving the production cost of the toilet. Among them, the climbing section and the ceramic body are fixedly connected by one or more of bonding, clamping and bolting.

[0082] In this embodiment, a first screw hole 12 is provided on the end surface at the sewage inlet 11, and a second screw hole 211 is provided on the end surface of the climbing section 21 close to the sewage inlet 11, so that the climbing section 21 and the ceramic body 1 can be fixedly connected by bolts, and the connection is more secure. In addition, a sealing member 6 is provided between the climbing section 21 and the ceramic body 1 to achieve sealing between the climbing section 21 and the ceramic body 1 to prevent water leakage, and the sealing member 6 can be a sealing rubber.

[0083] In addition, a positioning protrusion 212 is provided on the end surface of the climbing section 21 close to the sewage inlet 11, and a positioning groove 13 cooperating with the positioning protrusion 212 is provided on the end surface at the sewage inlet 11. When the climbing section 21 is assembled with the ceramic body 1, the positioning protrusion 212 can be inserted into the positioning groove to achieve assembly positioning of the climbing section 21 and the ceramic body 1, so that the assembly accuracy is higher. Among them, the specific position and number of the positioning protrusion and the positioning groove can be set as needed, and the positions of the positioning protrusion and the positioning groove can also be interchanged.

[0084] Furthermore, the climbing section 21 and the horizontal section 22 adopt an integrated structure, and the horizontal section 22 and the descending section 23 adopt a split structure. Of course, the climbing section and the horizontal section adopt a split structure, and the horizontal section and the descending section adopt an integrated structure; or the climbing section, the horizontal section and the descending section adopt an integrated structure; or the climbing section, the horizontal section and the descending section adopt a split structure, all of which are within the protection scope of the present invention.

[0085] Example 5

[0086] When the descending section is directly connected to the climbing section, that is, the sewage pipe only includes the descending section and the climbing section, and does not include the horizontal section, the descending section and the climbing section adopt a split structure, and the descending section can adopt an ordinary sewage plastic pipe, which can save the production cost of the toilet and facilitate the production, storage, transportation and installation of the toilet.

[0087] Of course, the descending section and the climbing section may also adopt an integrated structure to make the toilet structure simpler.

[0088] The above is only a specific embodiment of the present invention. Under the above teachings of the present invention, those skilled in the art can make other improvements or modifications on the basis of the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present invention, and the protection scope of the present invention shall be based on the protection scope of the claims.
