[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention provides a hidden water tank structure and a toilet for a toilet, which have a simple structure, are easy to manufacture, easy to implement and have a low cost, and solve the problems brought by the concealed installation of the existing toilet water tank. The technical solution of the present invention directly abandons the way of the concealed water tank at the rear of the traditional toilet, and by arranging a water storage tank (used as a water tank) below 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 self - contained water tank at the rear of the traditional toilet. Moreover, during concealed installation, the occupied area of the wall can be reduced, 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. Also, because the water tank is placed below the toilet bowl, most of the important toilet accessories are placed outside the wall, so the after - sales maintenance is simple and the installation and maintenance difficulty is lower.

[0017] (2) In this technical solution, since the height of the connection position between the water storage tank and the water inlet chamber is higher than or equal to the height of the connection position between the water storage tank and the water guiding and draining path, the water flowing into the water storage tank from the water inlet chamber will not flow back into the water inlet chamber, solving the problem of water flowing back into the water inlet chamber to ensure the smooth flow of water during the flow process.

[0018] (3) In this technical solution, in order to guide the water to better drain to the water guiding and draining path, a drain port connecting to the water guiding and draining path is provided on the upper side wall or the bottom wall of the water storage tank; this drain port is mainly arranged at the bottom wall position of the water storage tank; in this way, the water in the water storage tank can be effectively emptied and there will be no remaining water accumulated in the water storage tank.

[0019] (4) In this technical solution, an open water inlet is also provided on the water storage tank, and the water storage tank is communicated with the water inlet chamber through the water inlet; in this way, the water flow rate entering the water storage tank through the water inlet chamber is faster, and even if it exceeds the volume that the water storage tank can accommodate, the water in the water storage tank is not easy to fill the water storage tank, effectively reducing the pressure on the water storage tank.

[0020] (5) In this technical solution, the water storage tank is designed in a "U"-shaped layout structure, which can effectively reduce the occupied space and area of the entire water storage tank under the toilet, and can also ensure that the water storage capacity of the entire water storage tank is not too small, reducing the space occupation while ensuring the water storage capacity.

[0032] Please refer to Figures 1 to 4 。

[0033] This embodiment provides a concealed water tank structure for a toilet 1, which has a simple structure, is easy to manufacture, easy to implement and has a low cost, and solves the problems brought by the concealed installation of the water tank of the existing toilet 1; the concealed water tank structure is mainly formed on the toilet body to be able to supply water to the toilet bowl 11 of the toilet 1, and this structure includes: a water storage tank 2, a water inlet chamber 3 and a water guiding and draining path 4; wherein,

[0034] The water storage tank 2 is mainly arranged directly below the toilet bowl 11 of the toilet 1; this water storage tank 2 replaces the rear water tank of the traditional toilet 1, which can not only effectively save space but also be extremely convenient to install. In this embodiment, when the toilet 1 is manufactured, a split assembly process is usually adopted, that is, the toilet 1 is divided into two halves, and each half is hollowed out with half of the water storage tank 2, and finally the two halves of the toilet 1 are assembled and fixed to realize the built-in water storage tank 2 of the toilet 1. Therefore, the water storage tank 2 is mainly integrally formed below the toilet bowl 11 of the toilet 1, with a more stable overall structure, simple manufacturing and easy implementation. However, in other embodiments, the water storage tank 2 can also be split and arranged below the toilet bowl 11 for direct disassembly and assembly.

[0035] The water inlet chamber 3 is opened at the rear side of the toilet 1, communicates with the water storage tank 2, and injects water into the water storage tank 2 through the water injection member 5 (mainly configured as a traditional water inlet valve) in the water inlet chamber 3.

[0036] The water guiding and draining path 4 is mainly integrally formed on the water storage tank 2 and is connected to the pressurized flushing assembly, and the water in the water storage tank 2 is pumped out to the flushing water channel 12 of the toilet 1 through the pressurized flushing assembly to flush the toilet bowl 11. In this embodiment, the pressurized flushing assembly includes a water pump 51, a water suction pipe 52 and a drain pipe 53 provided on the flushing water channel 12 of the toilet 1. The water suction pipe 52 and the drain pipe 53 are respectively connected to the water guiding and draining path 4 and the toilet bowl 11 in a corresponding manner. When the water pump 51 works, the water in the water storage tank 2 flows through the water suction pipe 52 and the drain pipe 53 and is flushed to the pot surface of the toilet bowl 11 for flushing.

[0037] In other embodiments, when the water storage tank 2, the water inlet chamber 3 and the water guiding and draining path 4 are arranged on the toilet 1, each of them can be arranged in a split manner, that is, the water storage tank 2 is separately placed below the toilet bowl 11, the water inlet chamber 3 is arranged inside the toilet 1 in the form of a water inlet bucket, and the water guiding and draining path 4 is directly replaced by a single water pipe. This way is not only more convenient for daily disassembly and assembly, but also has lower processing requirements, but the overall structural strength is not stable enough, and all the structural components need to be reassembled later, with a cumbersome process.

[0038] In this embodiment, at least one drain port 21 connected to the water guiding and draining path 4 is provided on the water storage tank 2; for example, in order to increase the drainage volume, two or more water guiding and draining paths 4 and water suction pipes 52 are provided, and the number of corresponding drain ports 21 should also be corresponding.

[0039] In this embodiment, two different installation positions of the drain outlet 21 are exemplified: First, if the water guide and drainage path 4 is located at the side wall position of the water storage tank 2, the corresponding drain outlet 21 should also be set at the side wall position of the water storage tank 2 for correspondence. In this way, when the water suction pipe 52 is connected, it has to extend to the side wall of the water storage tank 2 to be conductively connected to the water guide and drainage path 4. In this way, the water inside the water storage tank 2 is not easily sucked out, that is, the low-level water flow below the height of the side wall position cannot be pumped out. Second, if the water guide and drainage path 4 is located at the bottom wall position of the water storage tank 2, the corresponding drain outlet 21 should also be set at the bottom wall position of the water storage tank 2 for correspondence. In this way, when the water suction pipe 52 is connected, it has to extend to the bottom wall of the water storage tank 2 to be conductively connected to the water guide and drainage path 4. This method can ensure that the water flow can be pumped out regardless of the water level height, and can effectively empty and pump out the water in the water storage tank 2.

[0040] In this embodiment, regardless of whether the drain outlet 21 and the water guide and drainage path 4 are located at the bottom wall or the side wall position of the water storage tank 2, the height of the position where the water storage tank 2 communicates with the water inlet chamber 3 is higher than or equal to the height of the position where the water storage tank 2 is connected to the water guide and drainage path 4. In this way, the water flow entering the water storage tank 2 from the water inlet chamber 3 will not flow back into the water inlet chamber 3.

[0041] In this embodiment, the bottom wall of the water storage tank 2 is inclined and concentrated towards the drain outlet 21 to guide the water flow inside the water storage tank 2 to be inclined and concentrated towards the drain outlet 21. In this way, when the water is pumped out of the water storage tank 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. At the same time, it is easier to empty the water in the water storage tank 2, and the remaining water can be quickly discharged without leaving any remaining water.

[0042] In this embodiment, an open water inlet 22 is further provided on the water storage tank 2. The water storage tank 2 is directly communicated with the water inlet chamber 3 through the water inlet 22. The size of the water inlet 22 is not limited and it is not adaptively connected to any water pipe. In this way, the water flow rate entering the water storage tank 2 from the water inlet chamber 3 is not restricted, and its water flow speed is faster. Moreover, even if the water flow rate exceeds the volume that the water storage tank 2 can accommodate, the water will automatically overflow partially into the water inlet chamber 3 for partial water storage, rather than filling the water storage tank 2, causing the water storage tank 2 to be filled and deformed.

[0043] In this embodiment, the water storage tank 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 tank 2 located below the toilet 1.

[0044] The usage process of the present utility model:

[0045] The main control board (not shown in the figure) on the toilet 1 controls the start and stop of the water pump 51. When the water pump 51 is running, the water in the water storage tank 2 is pumped out through the water suction pipe 52 and discharged into the drain pipe 53 and then discharged through the flushing water channel 12. During this process, the water suction pipe 52 continuously increases the water pressure. The water discharged from the flushing water channel 12 will flush onto the surface of the toilet bowl 11. When the water in the water storage tank 2 is pumped out again, the water flows along the inclined surface of the water storage tank 2 towards the drain outlet 21 and is concentrated until it is emptied. During this process, the water injection member 5 has been continuously replenishing water for the water storage tank 2 until the water storage tank 2 is filled. Therefore, in this utility model, the traditional method of installing a hidden water tank at the back of the toilet 1 is directly abandoned. By setting a water storage tank 2 (used as a water tank) below the toilet bowl 11 of the toilet 1, it can not only function to hide the water tank, but also directly avoid the drawbacks brought by the traditional built-in water tank at the back of the toilet 1. Moreover, during the concealed installation, the occupied area of the wall can be reduced. The size of the supporting iron frame required is only one-half or even one-third of the original, effectively reducing the installation cost. Also, because the water tank is built-in below the toilet bowl 11, most of the important accessories of the toilet 1 are externally placed outside the wall, making after-sales maintenance simple and the installation and maintenance difficulty 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, can obtain modifications, equivalent replacements, or other improvements to the embodiments of the present utility model or some of its technical features, which should all be included within the protection scope of the present utility model.
