Description

Technical Field

[0001] This application relates to a flushing system, and more particularly to a flushing system for a toilet. This application also relates to a toilet having the above-described flushing system. Background Technology

[0002] Current toilet flushing systems include a main flush line and a washbasin line. Generally, both the main flush line and the washbasin line are supplied with water simultaneously from the tank's outlet. This shared tank supply leads to two problems:

[0003] First, since both the main flushing pipeline and the washing ring pipeline are supplied with water from the water tank, the water output control of the two pipelines often cannot meet the requirement of being independent and separate. However, the flushing functions of the main flushing pipeline and the washing ring pipeline are very different, and the flushing paths are also different. Therefore, in some cases, it is necessary to make the control of the main flushing pipeline and the washing ring pipeline more independent and variable.

[0004] Secondly, since both the main flush pipe and the wash seat pipe are supplied with water from the water tank, in order to meet the water supply requirements, there must be a requirement for the size of the water tank, which makes the overall size of the toilet larger, inconvenient to install, and unsightly.

[0005] Application content

[0006] In response to the above problems, this application discloses a toilet flushing system to overcome or at least partially solve the above problems.

[0007] This application also discloses a toilet having the above-described flushing system.

[0008] To achieve the above objectives, this application adopts the following technical solution:

[0009] A toilet flushing system is provided, comprising a pressure regulating valve, a flushing valve, a washbasin piping, a water tank, a water pump, and a main flushing piping. The pressure regulating valve is connected to an external water source. The flushing valve is connected to the pressure regulating valve and includes a main flush outlet and a washbasin outlet. The washbasin piping is connected to the washbasin outlet of the flushing valve. The water tank is connected to the main flush outlet of the flushing valve. The water pump is connected to the water tank. The main flushing piping is connected to the water pump, which pumps liquid from the water tank into the main flushing piping.

[0010] The flushing system described above controls the flushing actions of the seat washing pipe and the flushing pipe independently. The two pipes can work together to achieve more diverse flushing strategies and improve the flushing effect. In addition, the water tank's storage capacity does not need to take into account the water demand of the seat washing pipe. The smaller water tank saves space, making the overall toilet smaller and more aesthetically pleasing.

[0011] In one illustrative embodiment of a toilet flushing system, the system further includes a flush valve control unit, which controls the opening and closing of the main flush outlet and / or the washbasin outlet. This structure contributes to a more compact overall design, especially since simultaneously controlling the opening and closing of both the main flush outlet and the washbasin outlet on the flush valve side allows for more precise control of the water pressure in the washbasin pipeline, ensuring effective flushing.

[0012] In one illustrative embodiment of a toilet flushing system, the system further includes a check valve and a check flow path. The check valve is connected between the water pump and the main flush line to prevent liquid in the main flush line from flowing back to the water pump. One end of the check flow path is connected to the main flush line side of the check valve, and the other end is connected to the water tank. The combination of the check flow path and the check valve effectively solves the siphon problem in the main flush line and the backflow problem after the system is blocked.

[0013] In one illustrative embodiment of the toilet flushing system, the position where the check valve is connected to the backflow preventer is higher than the position where the main flush valve is connected to the backflow preventer in the vertical direction.

[0014] In one illustrative embodiment of a toilet flushing system, the highest point of the backflow preventer is higher than the overflow surface of the toilet in the vertical direction.

[0015] In one illustrative embodiment of a toilet flushing system, the check valve is positioned below the overflow surface of the toilet in the vertical direction. This design allows for a smaller tank size, saving more space.

[0016] In one illustrative embodiment of a toilet flushing system, a backflow preventer is connected to the tank from the top wall.

[0017] In one illustrative embodiment of a toilet flushing system, along the height of the toilet, the flush valve is connected to a pressure regulating valve from above, with the main flush outlet and the washbasin outlet of the flush valve opening downwards. Along the width of the toilet, the main flush outlet and the washbasin outlet are located on either side of the flush valve. This structural design allows for a more compact and rational flushing system, makes the washbasin piping connected to the flush valve easier to arrange and position, and saves on the length of the piping connecting the water tank to the main flush outlet.

[0018] In one illustrative embodiment of the toilet, the water tank is located on the side of the flush valve where the main flush outlet is located, along the width of the toilet.

[0019] This application also provides a toilet, which includes a bracket and the aforementioned flushing system, the flushing system being integrated into the bracket. The overall structure of the integrated toilet is very compact and reasonable. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0047] To keep the drawings concise, only the parts relevant to this application are shown schematically in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0048] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0049] Figure 1 A three-dimensional structural diagram illustrating an exemplary embodiment of a toilet flushing system. (Example) Figure 1 As shown, the toilet's flushing system includes a pressure regulating valve 10, a flushing valve 20, a wash seat pipe 30, a water tank 40, a water pump 50, and a main flush pipe 60. See also... Figure 2 , Figure 2 Used to explain Figure 1 The diagram shown is a partial integrated 3D structural representation of the toilet's flushing system. The individual components are not clearly shown. Figure 2 The structure of the washing ring pipe 30 is omitted. Figure 2 Compared to Figure 1 The structure in the diagram also changes angles; the angular relationships can be determined by referring to the coordinate system in the diagram.

[0050] The pressure regulating valve 10 can be connected to an external water source, such as a tap water system. It stabilizes the water pressure entering the flushing system from the external source. The flushing valve 20 can be connected to the pressure regulating valve 10. Here, "connection" refers to the connection of the water pipe; after connection, water can flow from the pressure regulating valve 10 to the flushing valve 20. The direction of water flow is indicated by a dashed arrow in the diagram, and similar descriptions will not be repeated later. Specifically, the flushing valve 20 is connected to the pressure regulating valve 10 via a connecting pipe 21, completing the water pipe connection between the pressure regulating valve 10 and the flushing valve 20.

[0051] like Figure 2 As shown, the flushing valve 20 itself is also equipped with a main flushing outlet 24 and a ring washing outlet 23. The ring washing pipeline 30 can be connected to the ring washing outlet 23 of the flushing valve 20, and the ring washing pipeline 30 can complete the ring washing action with the cooperation of the pressure stabilizing valve 10 and the flushing valve 20.

[0052] like Figure 2 The water tank 40 can be connected to the main flush outlet 24 of the flush valve 20. Specifically, the water tank 40 is connected to the main flush outlet 24 of the flush valve 20 through the water tank inlet pipe 44, so that the flush valve 20 can supply water to the water tank 40. Normally, to avoid noise after the water tank is filled with water, the water tank inlet pipe 44 is connected to the bottom of the water tank.

[0053] like Figure 2 The water pump 50 can be connected to the water tank 40. Specifically, the water pump 50 is connected to the water tank 40 through the water tank outlet pipe 45. Normally, in order to facilitate pumping out the liquid inside the water tank 40, the water tank outlet pipe 45 is connected to the bottom of the water tank.

[0054] like Figure 2 As shown, the main flushing pipe 60 is connected to the water pump 50, which can pump the liquid in the water tank into the main flushing pipe 60, so that the main flushing pipe 60 can complete the main flushing cleaning action.

[0055] In the above structure, the washing ring pipeline 30 is directly connected to the flushing valve 20. Utilizing the pressure regulating valve 10 to adjust the inlet water pressure and the flushing valve 20 to control the water flow, the washing ring cleaning action can be completed independently. Meanwhile, the main flushing pipeline 60 is still supplied with water through the water tank 40 and the water pump 50, and the main flushing action is independently controlled by the water pump 50. Therefore, the flushing actions of the washing ring pipeline and the flushing pipeline are controlled independently, and the two pipelines can cooperate to achieve more diverse flushing strategies and improve the flushing effect.

[0056] Furthermore, the water supply side of the flush pipe 30 can be understood as an external water source, and the water supply side of the main flush pipe 60 can be understood as the water tank 40 after water storage. Therefore, the water storage capacity of the water tank 40 does not need to consider the water demand of the flush pipe 30, but only needs to meet the water demand of the main flush pipe 60. A smaller water tank saves space; for example, it can be made into a sunken tank, making the overall toilet smaller and more aesthetically pleasing. The overall structure of the toilet can be seen in [reference needed]. Figure 3 , Figure 3 The diagram illustrates the three-dimensional structure of the toilet, showing how the water tank 40 is reduced in size, making the overall structure more compact and smaller in appearance.

[0057] In the embodiment shown in Figure 1, the flushing system further includes a flushing valve control unit 22, which can control the opening and closing of the main flushing outlet and / or the washing ring outlet of the flushing valve. Controlling the water inlet of the water tank 40 and / or controlling the flushing action of the washing ring pipeline on the flushing valve side helps to make the overall structure more compact. In particular, the ability to simultaneously control the opening and closing of the main flushing outlet and the washing ring outlet on the flushing valve side allows for more precise control of the water pressure in the washing ring pipeline, ensuring the flushing effect.

[0058] It is important to note that Figure 1 The flushing valve control unit 22 in the figure is only used to illustrate the control relationship between the structures. The solid arrow at the flushing valve control unit 22 indicates the control relationship. Those skilled in the art will understand that the flushing valve control unit 22 shown in the figure is not the actual structural relationship. Depending on the design requirements, in the actual structural design, the flushing valve control unit 22 can be independent of the flushing valve 20 or integrated into the flushing valve 20.

[0059] exist Figures 1 to 3 In the illustrated embodiment, the toilet flushing system also includes a check valve 70 and a check flow path 72. The check valve 70 is connected between the water pump 50 and the main flush line 60, meaning that the liquid pumped by the water pump 50 from the water tank 40 will first pass through the check valve 70 before entering the main flush line 60. The check valve 70 acts as a one-way valve, preventing liquid in the main flush line 60 from flowing back to the water pump 50 and the water tank 40. One end of the check flow path 72 is connected to the main flush line side of the check valve, and the other end is connected to the water tank 40.

[0060] Since the washing pipe 30 can be separated at the position of the flushing valve 20, the volume of the water tank 40 can be reduced to make a submerged water tank. The structure of the submerged water tank also needs to consider the siphon problem of the main flushing pipe 60 and the backflow problem after water blockage. The cooperation of the check water circuit 72 and the check valve 70 can effectively solve the above problems.

[0061] When the water tank 40 is full, the check valve 72 is sealed by the liquid in the water tank. After the water pump 50 starts working, the liquid level in the water tank 40 drops, and the check valve 72 is connected to the gas in the water tank 40. The check valve 72 constitutes a vacuum breaker. At the moment after the water pump 50 stops working, the main flushing pipe 60, where the water level drops, draws air from the vacuum breaker to prevent the main flushing pipe 60 from siphoning.

[0062] When the toilet becomes clogged, as the water level inside the toilet ceramic rises, the liquid in the flush pipe 60 is pushed back to the check valve. The check valve 70 prevents the liquid from flowing to the pump side. Furthermore, because the check water passage 72 is sealed by the liquid in the tank, the gas pressure in the check water passage 72 gradually increases, and the liquid in the flush pipe 60 cannot flow into the tank through the check water passage 72.

[0063] Specifically, in the height direction Z shown in the figure, the position where the check valve 70 is connected to the check valve 72 should be higher than the position where the main flushing pipe 60 is connected to the check valve 70, which can further ensure the above-mentioned effect.

[0064] In the height direction Z shown in the figure, the highest point 721 of the backflow preventer 72 is higher than the overflow surface of the toilet, while the backflow preventer 70 is lower than the overflow surface of the toilet. The overflow surface of the toilet refers to the overflow surface of the basin cavity formed by the ceramic body of the toilet. The above design can achieve a smaller volume of the water tank 40 while ensuring the above effects, thus saving more space.

[0065] In addition, in the embodiment shown in the figure, the backflow prevention water passage 72 is connected to the water tank 40 from the top wall 42 of the water tank 40, making the above effect more stable and reliable.

[0066] exist Figures 1 to 3 In the illustrated embodiment, along the height direction Z of the toilet, the flush valve 20 is connected to the pressure regulating valve 10 from above, and the main flush outlet 24 and the washbasin outlet 23 of the flush valve 20 are located downwards. Along the width direction X of the toilet, the main flush outlet 24 and the washbasin outlet 23 are located on opposite sides of the flush valve 20. This structural design allows for a more compact and rational flushing system, making the washbasin piping connected to the flush valve 20 easier to arrange and position, and saving the length of the piping connecting the water tank 40 to the main flush outlet 24. In particular, in the embodiment shown, the water tank 40 and the flush valve 20 are also arranged along the width direction of the toilet, with the water tank 40 located on the side of the flush valve 20 where the main flush outlet 24 is located.

[0067] This application also provides a toilet, see [link to relevant documentation] Figure 3 It includes a support frame 80 and the aforementioned flushing system, which can be integrated into the support frame 80. The overall structure is very compact and reasonable.

[0068] The above description is merely a specific embodiment of this application. Under the guidance of the above teachings, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
