Description

Technical Field

[0001] The present application relates to a flushing system, in particular to a flushing system for a toilet. The present application also relates to a toilet having the above-mentioned flushing system. Background Art

[0002] Floor-standing and wall-mounted miniaturized toilets, with their advantages of small footprint and compact size, are becoming a trend in the market. However, the internal space of the ceramic body of these toilets is relatively small, resulting in limited space for the water tank system. To ensure flushing performance, most existing toilets use the following two solutions for their flushing system: one is to connect the wash ring water channel to the tap water pipe and directly flush the wash ring with tap water. Although this can reduce the size requirement of the water tank, the wash ring is affected by the tap water pressure during flushing, making zero-pressure flushing impossible. The other is to bury the toilet tank in the wall. Although this method frees the volume of the water tank from the internal space of the toilet ceramic body, it increases the workload of toilet assembly and makes maintenance difficult. Summary of the Invention

[0003] In response to the above problems, the present application provides a toilet flushing system to overcome the above problems or at least partially solve the above problems.

[0004] The application also discloses a toilet with the flushing system.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] The present application provides a toilet flushing system comprising a water tank, a water inlet valve, and a water pump. The water tank comprises an inlet tank and an outlet tank, each of which can be positioned on either side of the toilet's sewage pipe. The water tank also comprises a connecting passageway between the inlet and outlet tanks, the connecting passageway being positioned below the sewage pipe. The top of the inlet tank is provided with an inlet mounting hole, and the top of the outlet tank is provided with an outlet mounting hole. The inlet valve is mounted to the inlet tank via the inlet mounting hole. The water pump comprises a suspension portion and a pump body, which is mounted to the outlet mounting hole via the suspension portion, allowing the pump body to be suspended within the outlet tank.

[0007] The flushing system of the above-mentioned toilet fully utilizes the space on both sides of the toilet sewage pipe, making the overall volume of the toilet more compact while ensuring sufficient flushing water volume. To accommodate the shape of the water tank, the flushing system of the above-mentioned toilet allows the water inlet valve and water pump to be installed vertically with the water tank. This not only facilitates the disassembly and assembly of the water inlet valve and water pump, but also ensures the control of the water inflow and outflow of the water tank. The water pump is mainly fixed by a suspended method. This fixing method is stable and reliable, and does not require a fixed structure inside the water tank to fix the water pump, thus avoiding the occupation of the internal space of the water tank and ensuring the water storage capacity in the water tank. The suspended fixing method is more convenient for operation during maintenance and replacement.

[0008] In an exemplary embodiment of the flushing system of the toilet, the water inlet of the water pump body faces the bottom of the water tank. This structural design does not require additional design of other fixing parts such as water inlet hose and clamp.

[0009] In an exemplary embodiment of a toilet flushing system, the distance h between the water inlet of the water pump body and the bottom of the water outlet tank is ≥ 20 mm. This height can ensure that impurities at the bottom of the water outlet tank will not be pumped into the water pump body while ensuring a good pumping effect.

[0010] In one exemplary embodiment of a toilet flushing system, the water pump further comprises an upper pump cover and a lower pump cover. A suspension portion is formed on the upper pump cover, and the water pump body is clamped between the upper and lower pump covers. This design takes into account both production and assembly difficulties while ensuring stable operation of the water pump.

[0011] In one exemplary embodiment of a toilet flushing system, a water pump lower cover is formed with a receiving groove capable of accommodating the water pump body. The water pump also includes a shock-absorbing sleeve that can be mounted on the outer surface of the water pump body and is matched and placed in the receiving groove. The provision of the shock-absorbing sleeve effectively reduces the operating noise of the water pump body and makes the overall structure of the water pump more stable and reliable.

[0012] In an exemplary embodiment of the flushing system of the toilet, a positioning bracket is further provided on the top outer surface of the water inlet tank, and the water inlet of the water inlet valve is positioned on the positioning bracket. This positioning method is simple and reliable, and facilitates the disassembly and assembly of the water inlet valve.

[0013] In an exemplary embodiment of a toilet flushing system, the height of the water outlet of the water inlet valve in the water inlet tank is lower than the opening height of the connecting channel in the water inlet tank, so as to ensure that after the water in the water tank is pumped away by the water pump, the water outlet of the water inlet valve can still be located below the remaining water level in the water inlet tank, thereby reducing the water inlet noise.

[0014] In an exemplary embodiment of the flushing system of the toilet, the flushing system further includes a water outlet pipe connected to the water outlet of the water pump body and capable of extending from the water outlet mounting hole of the water outlet tank. The above structure facilitates the disassembly and maintenance of the water pump as a whole.

[0015] In an exemplary embodiment of a toilet flushing system, the flushing system further includes a switching valve, a flushing line, and a main flushing line. The switching valve is connected to the water outlet pipe, the flushing line is connected to the switching valve, and the main flushing line is connected to the switching valve.

[0016] The present application also provides a toilet, which includes a sewage pipe and the above-mentioned flushing system, the water tank includes an inlet tank and an outlet tank that can be located on both sides of the sewage pipe respectively, and the connecting channel is located below the sewage pipe.

[0049] To make the purpose, technical solutions, and advantages of this application more clear, the following will provide a clear and complete description of the technical solutions of this application in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0051] To simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled.

[0052] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0053] Figure 1 A schematic diagram of an exploded structure for illustrating an exemplary embodiment of a flushing system of a toilet. Figure 2 yes Figure 1 The structural diagram of the combined state of the flushing system of the toilet is shown. Figure 3 To illustrate Figure 2 The partial structural cross-sectional diagram of the flushing system of the toilet in the AA direction is shown. Figure 1 、 Figure 2 and Figure 3 As shown, the flushing system of the toilet includes a water tank 10 , a water inlet valve 20 and a water pump 40 .

[0054] The water tank 10 includes an inlet tank 12 and an outlet tank 14 that can be located on either side of a toilet sewage pipe 62. The water tank 10 also includes a connecting passage 16 connecting the inlet tank 12 and the outlet tank 14. The connecting passage 16 is located below the sewage pipe 62, making the water tank 10 have an overall U-shaped or H-shaped shape.

[0055] A water inlet installation hole 122 is provided on the top of the water inlet box 12 for installing the water inlet valve 20. The water inlet valve 20 is installed to the water inlet box 20. Figure 2 and Figure 3 , so that water is supplied to the water inlet tank 20, and the water in the water inlet tank 20 enters the water outlet tank 14 through the communication channel 16.

[0056] A water outlet mounting hole 142 is provided on the top of the water outlet box 14 for mounting a water pump 40. The water pump 40 is mounted in a hanging manner. The water pump 40 comprises a hanging portion 422 and a water pump body 46. The hanging portion 422 can be mounted on the water outlet mounting hole 142 of the water outlet box 14 so that the water pump body 46 can be hung in the water outlet box. Figure 2 and Figure 3 , to pump out the water in the water outlet tank 142 for toilet flushing, such as for toilet flushing and / or main flushing. Figure 1The water pump body 46 shown is also covered by other structures. For the specific structure of the water pump body 46, please refer to Figure 4 and Figure 5 .

[0057] The flushing system of the above-mentioned toilet features a specially designed water tank that fully utilizes the space on both sides of the toilet sewage pipe 62, miniaturizing the overall size of the toilet while ensuring sufficient flushing water volume. To accommodate the shape of the water tank, the flushing system also improves the mounting structure of the water inlet valve 20 and water pump 40, allowing both to be mounted vertically within the water tank 10. This not only facilitates assembly and disassembly of the water inlet valve 20 and water pump 40, but also ensures control of the water inflow and outflow from the water tank, especially when repairs or replacements are necessary. The water pump 40 primarily utilizes a suspended mounting method, which is stable and reliable. This eliminates the need for a fixed structure within the water tank to secure the pump 40, thus avoiding space occupation within the water tank and ensuring sufficient water storage within the tank. The suspended mounting method also facilitates maintenance and replacement.

[0058] exist Figure 1 In the embodiment shown, the water inlet 462 of the water pump body 46 is toward the bottom of the water tank 10, that is, toward the bottom of the water outlet tank 14, and can be seen at the same time. Figure 3 , Figure 3 To illustrate Figure 2 The schematic diagram of the partial structure of the flushing system of the toilet in the AA direction is shown. Compared with the structure design with the water inlet 462 facing downward, the position of pumping water from the inside of the water tank 10 is lower, and there is no need to design additional water inlet hoses and clamps and other fixing parts. In one embodiment, Figure 3 The distance h between the water inlet 462 of the water pump body 46 and the bottom of the water outlet tank 14 is ≥ 20 mm. This height can ensure that impurities at the bottom of the water outlet tank 14 will not be pumped into the water pump body 46 while ensuring a good pumping effect.

[0059] exist Figure 1 and Figure 2 In the embodiment shown, a positioning bracket 124 is further provided on the top outer surface of the water inlet box 12. The water inlet 24 of the water inlet valve 20 is positioned on the positioning bracket 124 to complete the installation and positioning of the water inlet valve 20. This positioning method is simple and reliable, and facilitates the installation and removal of the water inlet valve 20. After installation, the height of the water outlet 26 of the water inlet valve 20 in the water inlet box 12 is lower than the opening height of the connecting channel 16 in the water inlet box 12. Figure 3 , to ensure that after the water in the water tank 10 is pumped away by the water pump 40, the water outlet 26 of the water inlet valve 20 can still be located below the remaining water level in the water inlet tank 12, thereby reducing the water inlet noise.

[0060] Figure 4A schematic structural diagram of an exploded state for illustrating a schematic implementation of a water pump of a toilet flushing system. Figure 5 A schematic diagram of another exploded state of a schematic embodiment of a water pump for a toilet flushing system. Figure 4 and Figure 5 As shown, the water pump 40 further includes a water pump upper cover 42 and a water pump lower cover 44, wherein a hanging portion 422 is formed on the water pump upper cover 42, and the water pump body 46 is clamped between the water pump upper cover 42 and the water pump lower cover 44. This design takes into account both production and assembly difficulties and can ensure the stability of the water pump 40.

[0061] exist Figure 4 and Figure 5 In the illustrated embodiment, the water pump lower cover 44 is formed with a receiving groove 446 capable of accommodating the water pump body 46. The water pump 40 also includes a shock-absorbing sleeve 48, which can be mounted on the outer surface of the water pump body 46 and is adapted to fit within the receiving groove 446 of the water pump lower cover 44. The water pump body 46 inevitably vibrates during operation, and the provision of the shock-absorbing sleeve 48 effectively reduces operating noise from the water pump body 46 and makes the overall structure of the water pump 40 more stable and reliable.

[0062] In one embodiment, the flushing system of the toilet further includes a water outlet pipe 49, which is connected to the water outlet 464 of the water pump body 46. Figure 6 , and after connection, the water outlet pipe 49 can extend from the water outlet installation hole 142 of the water outlet box 14, see Figure 7 In this way, the structures connected to the water pump 40 can all extend from the water outlet mounting hole 142 of the water outlet box 14, making it convenient for the overall disassembly and maintenance.

[0063] Figure 8 for Figure 7 Schematic diagram of the structure in direction B. Figure 7 and Figure 8 In the embodiment shown, the flushing system of the toilet further includes a switching valve 50, a wash ring pipeline 52 and a main flushing pipeline 54 ( Figure 7 Switching valve 50 connects to outlet pipe 49, ring wash line 52 connects to switching valve 50, and main flush line 54 connects to switching valve 50. Switching valve 50 controls the flow of water pumped from the water tank by water pump 40 into ring wash line 52 and / or main flush line 54.

[0064] This application also provides a toilet, see Figure 1 、 Figure 2 、 Figure 7 and Figure 8, which includes a sewage pipe and the above-mentioned flushing system, wherein the water tank 10 of the flushing system includes a water inlet tank 12 and a water outlet tank 14 which can be located on both sides of the sewage pipe 62 respectively, and the connecting channel 16 is located below the sewage pipe 62.
