Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to a wall-mounted toilet with a wall drain. Background Art

[0002] At present, in order to save space and ensure the aesthetics of the inner room of the toilet, wall-mounted toilets with concealed water tanks are mostly installed in the toilets of current families and hotels. However, such toilet structures usually have the following problems:

[0003] First, the accumulated water in the toilet cannot be reasonably guided to the outside of the toilet for discharge. When the daily sewage pipeline is blocked, the water in the toilet bowl may accumulate and flow back into the water inlet chamber, polluting the water inlet valve group connected to the municipal water in the water inlet chamber and indirectly causing the pollution of daily water use. Second, most existing toilets use a double-outlet water pipe for sequential flushing. That is, a concealed water tank, under the boosting effect of a pump body, not only needs to supply water to the brush ring water pipe to first clean the surface of the toilet bowl, but also needs to supply water to the main flushing water pipe to perform a jet flushing on the inlet of the sewage pipe later. Although this method can effectively achieve the purpose of flushing feces, the entire flushing process is extremely noisy, consumes a large amount of water, is slow, the installation of the two water pipes is also more troublesome, and the manufacturing cost increases. Third, the water tank of the toilet is located at the rear side. During the concealed installation process, a steel frame with a sufficient height needs to be pre-embedded in the wall, and then the water tank is supported and concealed in the wall through the steel frame. The water tank of this type of toilet can only rely on the wall to achieve the concealed installation function, and has certain space requirements for the interior of the wall. The installation is difficult, the cost is high, and it is easy to expand the damaged area of the wall, posing potential hazards. Fourth, the concealed installation of the water tank in the wall makes the disassembly and replacement of the water tank and toilet accessories extremely cumbersome later, and it needs to be taken out from the wall, making after-sales maintenance difficult;

[0004] In summary, existing toilets still need to be further improved to meet the actual use requirements. Content of the Utility Model

[0016] As can be seen from the above description of the present utility model, compared with the prior art, the present utility model has the following beneficial effects:

[0017] (1) The present utility model provides a wall-mounted toilet, which has a simple structure, is easy to install, easy to implement and has a low cost, and solves the problems of easy backflow of accumulated water, high noise, large water consumption and difficult installation of existing toilets; the technical solution of the present utility model, first of all, by setting an anti-backflow structure to guide the accumulated water in the toilet bowl to be discharged outside the toilet, even if the water inlet valve is damaged or the toilet is blocked, the accumulated water will not overflow everywhere and can be effectively discharged, and the problem of accumulated water pollution is effectively solved; secondly, directly abandon the traditional way of installing a hidden water tank at the back of the toilet, and by setting a water storage chamber (used as a water tank) under the toilet bowl of the toilet, it can not only play the function of hiding the water tank, but also directly avoid the disadvantages brought by the traditional built-in water tank at the back of the toilet. When installed hidden, it can reduce the occupied area of the wall, and the size of the supporting iron frame required is only one-half or even one-third of the original, effectively reducing the installation cost. And because the water tank is built into the lower part of the toilet bowl, most of the important toilet accessories are placed outside the wall, and the after-sales maintenance is simple in the later stage, and the installation and maintenance difficulty is also lower.

[0018] (2) In this technical solution, a swirling flushing drain port facing the pot surface of the toilet bowl is provided on the toilet body. The water flushed into the toilet bowl through this swirling flushing drain port can form a swirling water flow along the pot surface, and this swirling water flow can also be used for ring flushing and main flushing at the same time; in this way, the pressurized flushing assembly only needs to supply water to this swirling flushing drain port during implementation to achieve daily flushing, with a small water consumption. And because the water flow is swirling on the pot surface, the whole flushing process has extremely low noise, and the pressurized flushing assembly can quickly complete the flushing with a one-time continuous pressurization.

[0019] (3) In this technical solution, the pot surface of the toilet bowl is inclined inwardly in a concentrated manner, so as to ensure that the water flow can form a swirling shape on the pot surface of the toilet bowl to wash the pot surface, with a larger flushing area and cleaner; and because the water flow is swirling, when the water flow flushes to the pipe orifice of the toilet sewage pipe, the water flow can be concentrated in the pipe orifice in a swirling manner, and its drainage pressure and potential energy are stronger. As long as the water flow is continuously pressurized, the flushing ability can be effectively guaranteed.

[0020] (4) In this technical solution, a lower drain port is provided in the water storage chamber, so that the water in the water storage chamber can be effectively emptied, and there will be no remaining water accumulated in the water storage chamber.

[0021] (5) In this technical solution, an independent drainage chamber and a water inlet chamber are arranged side by side at the back of the toilet bowl of the toilet body. Such a structural design and layout method can effectively reduce the volume of the whole toilet, and can also ensure that the accumulated water in the toilet bowl can be quickly discharged to the outside.

[0033] Please refer to Figures 1 to 4 。

[0034] This embodiment provides a wall-mounted toilet, which has a simple structure, is easy to install, easy to implement and has a low cost, and solves the problems of easy backflow of accumulated water, high noise, large water consumption and difficult installation of existing toilets; the toilet mainly includes a toilet body 1, a toilet bowl 11 formed on the toilet body 1, a sewage pipe 12, a water storage chamber 2, an anti-backflow structure 3, an inlet valve group 4 and a pressurized flushing assembly 5, wherein,

[0035] The toilet body 1, the toilet bowl 11 is communicated with the sewage pipe 12, and the outlet of the sewage pipe 12 mainly faces the rear side of the toilet body 1, that is, different from the conventional sewage pipe 12 with the outlet facing downwards; thus, when flushing the toilet in this toilet, instead of using the traditional siphon for sewage discharge, high-pressure potential energy water flow is used for flushing, that is, as long as the water flow pressure and potential energy are strong enough, the daily use can be realized by a one-time flushing of the water flow, without the need to use two outlet pipes in sequence like traditional toilets (one pipe is used to clean the surface of the toilet bowl 11 in a circular motion, and the water cup in the other pipe is pressurized to jet and flush the inlet of the sewage pipe 12), so only one outlet pipe is needed for the toilet in this embodiment;

[0036] The water storage chamber 2 is formed directly below the toilet bowl 11 in the toilet body 1 and is connected to the water inlet chamber 13 of the toilet body 1. The water storage chamber 2 mainly replaces the rear water tank of a traditional toilet. It can not only effectively save space but also be extremely convenient to install. In this embodiment, when manufacturing the toilet body 1, a split assembly process is usually adopted, that is, the two halves of the toilet body 1 are respectively hollowed out with half of the water storage chamber 2, and finally the two halves of the toilet body 1 are assembled and fixed to realize the built-in water storage chamber 2 of the toilet, which is simple to manufacture and easy to implement;

[0037] The anti-backflow structure 3 is mainly to solve the drawback that the water in the toilet bowl 11 of the toilet body 1 accumulates and overflows into the water inlet chamber 13. This structure is mainly formed on the toilet body 1 and includes at least two communicating grooves 31 / 32 arranged side by side at the rear of the toilet bowl 11. One of the communicating grooves 32 connects the toilet bowl 11 and the water inlet chamber 13 to guide the overflow water in the water inlet chamber 13 into the toilet bowl 11. The other communicating groove 31 connects the toilet bowl 11 to the outside. Its set height is lower than the height of the communicating groove 32 that connects the toilet bowl 11 and the water inlet chamber 13, so that the accumulated water in the toilet bowl 11 overflows and is discharged to the outside, and its set size is larger than the size of the communicating groove 32 that connects the toilet bowl 11 and the water inlet chamber 13. In this way, in the face of Scenario 1: when the toilet bowl 11 is blocked and accumulates water and overflows, the water will overflow into the communicating groove 31 with a lower height and be discharged to the outside, rather than overflowing into the communicating groove 32 with a higher height; Scenario 2: when the water inlet valve group 4 fails and the water in the water inlet chamber 13 accumulates seriously, the water flow can be discharged into the toilet bowl 11 through the communicating groove 32 connected to the water inlet chamber 13 and fill it up. At this time, because the size of the other communicating groove 31 connected to the outside is larger than the size of the communicating groove 32 here, the speed at which the water in the toilet bowl 11 is discharged to the outside will be greater than the speed at which the water in the water inlet chamber 13 is discharged into the toilet bowl 11, and there is no need to worry that the toilet bowl 11 will accumulate water quickly and cannot be discharged quickly;

[0038] The water inlet valve group 4 is mainly a traditional water inlet valve. It is installed in the water inlet chamber 13 and is used to supply water and cut off water to the water storage chamber 2;

[0039] The pressurized flushing assembly 5 is used to pump the water in the water storage chamber 2 out and discharge it into the flushing water channel 15 of the toilet body 1. This assembly includes a water pump 51, a water suction pipe 52 and a drain pipe 53 arranged in the flushing water channel 15. The water suction pipe 52 and the drain pipe 53 are respectively connected to the water storage chamber 2 and the toilet bowl 11 in correspondence. Among them, the water suction pipe 52 is connected to the lower discharge port 17 on the toilet body 1 (connecting the water storage chamber 2 and the pressurized flushing assembly 5), and the drain pipe 53 is installed on the flushing water channel 15 of the toilet body 1 and is connected to the swirl flushing drain port 16 at the outlet of the flushing water channel 15; when the water pump 51 works, the water in the water storage chamber 2 is pumped out through the water suction pipe 52, and then enters the drain pipe 53 after being pressurized by the water pump 51 and is pumped out and flushed onto the toilet bowl;

[0040] In this embodiment, the swirling flush drain port 16 is located at the outlet of the flushing water channel 15 and above the toilet bowl 11. The water outlet direction of the swirling flush drain port 16 faces the pot surface of the toilet bowl 11. The pot surface of the toilet bowl 11 is inclined inwardly (i.e., concentrated at the pipe orifice of the sewage pipe 12). In this way, the pressurized water flow can form a vortex on the pot surface of the toilet bowl 11. When the water flow reaches the pipe orifice of the sewage pipe 12 of the toilet bowl 11, the water flow can be concentrated in a vortex at the pipe orifice to generate a sufficient large pressure and potential energy to flush the object into the sewage pipe 12 and discharge it at one time. In this process, siphon is not adopted, but mainly the pressure of the water flow is used for brushing and flushing and main flushing.

[0041] In this embodiment, when it is necessary to empty the water in the water storage chamber 2 so that there is no remaining water in the water storage chamber 2, the design of the lower drain port 17 can effectively ensure that the remaining water is automatically discharged from the water storage chamber 2. For example, when all the water in the water storage chamber is pumped out by the pressurized flushing assembly into the flushing water channel and the inlet valve group is not replenishing water, there will be no remaining water accumulating in the water storage chamber, and the water in the water storage chamber can be effectively emptied.

[0042] In this embodiment, the bottom wall of the water storage chamber 2 is inclined and concentrated towards the lower drain port 17 to guide the water flow in the water storage chamber 2 to flow obliquely and concentratedly towards the lower drain port 17. In this way, when the water flow is pumped out of the water storage chamber 2, the flow direction of the water flow can be automatically guided to flow along the inclined surface of the bottom wall, reducing the working pressure of the water pump 51, and at the same time, it is easier to empty the water in the water storage chamber 2, and the remaining water can be quickly discharged without leaving remaining water.

[0043] In this embodiment, the water storage chamber 2 is arranged in a "U" shape around the sewage pipe of the toilet 1, which can effectively reduce the occupied space and area of the entire water storage chamber 2 below the toilet body 1.

[0044] In this embodiment, an independent drainage chamber 14 and the inlet chamber 13 are arranged side by side and separated at the rear side of the toilet bowl 11 of the toilet body. The drainage chamber 14 is communicated with the outside. The sewage pipe 12 and the pressurized flushing assembly 5 are both arranged in the drainage chamber 14. The water in the drainage chamber 14 will flow out of the toilet to the outside. The two communication grooves 31 / 32 respectively conduct the inlet chamber 13 and the drainage chamber 14 to the toilet bowl 11. In this way, the accumulated water in the toilet bowl 11 can be discharged to the drainage chamber 14 and then to the outside through the communication groove 31.

[0045] Working principle and usage process of the present utility model: The main control board (not shown in the figure) on the toilet controls the start and stop of the water pump 51; when the water pump 51 operates, the water in the water storage chamber 2 is pumped through the water suction pipe 52 and discharged into the drain pipe 53 and discharged from the swirl flushing drain port 16 of the flushing water channel 15. During this process, the water suction pipe 52 continuously increases the pressure of the water flow. The water flow discharged from the swirl flushing drain port 16 will flush onto the surface of the toilet bowl 11 and form a swirling water flow along the surface until the water flow concentrates at the pipe orifice of the sewage pipe 12 to generate a sufficient large pressure and potential energy to flush out the object at one time; when the water in the water storage chamber is pumped out again, the water flow all converges towards the drain port until it is emptied. During this process, the water injection component has been continuously replenishing water for the water storage chamber until the water storage chamber is filled. Therefore, the present utility model has a simple structure, is easy to install, easy to implement and has a low cost, and solves the problems of easy backflow of accumulated water, high noise, large water consumption and difficult installation of the existing toilet; for the technical solution of the present utility model, firstly, by setting the anti-backflow structure 3 to guide the accumulated water in the toilet bowl 11 to be discharged outside the toilet. Even if the inlet valve is damaged or the toilet is blocked, the accumulated water will not overflow everywhere and can be effectively discharged, and the problem of accumulated water pollution is effectively solved; secondly, by setting a water storage chamber 2 (used as a water tank) below the toilet bowl 11 of the toilet, it can not only play the function of hiding the water tank, but also directly eliminate the disadvantages brought by the traditional water tank behind the toilet. When installed secretly, it can reduce the occupied area of the wall. The size of the supporting iron frame required is only one-half or even one-third of the original, effectively reducing the installation cost. And because the water tank is placed inside the toilet bowl 11, most of the important toilet accessories are placed outside the wall, and the after-sales maintenance is simple in the later stage, and the installation and maintenance difficulty is also lower.

[0046] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation to the protection scope of the present utility model. Through the inspiration of the present utility model or the above embodiments, those of ordinary skill in the art, combined with common general knowledge, ordinary technical knowledge in the art and / or existing technologies, through logical analysis, reasoning or limited experiments, modifications, equivalent replacements or other improvements to the embodiments of the present utility model or some of its technical features can be obtained, and all should be included within the protection scope of the present utility model.
