Description

Technical Field

[0001] This utility model relates to the field of sanitary equipment technology, and in particular to a flushing pipe structure and toilet. Background Technology

[0002] There are two main flushing methods for existing squat toilets: one is perforated flushing, and the other is open-channel flushing. Perforated flushing uses multi-hole annular water outlets, which cover a wide range of water flow and can evenly flush away dirt on the edges and corners. It is especially suitable for cleaning stains adhering to the inner surface of the liner and is less likely to leave cleaning dead corners. However, the water flow from each hole is small and it is prone to clogging. Open-channel flushing uses a concentrated water outlet from the flushing trough. The single water flow has a strong impact force and can quickly flush large pieces of dirt into the drain outlet, which is highly efficient. However, the water flow can only cover the area below the flushing trough, and stains are easily left on the top wall of the flushing trough, requiring manual cleaning of dead corners.

[0003] Therefore, for squat toilets that use open water channels to flush ceramic surfaces, how to design the flushing pipes to reduce cleaning dead spots has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a flushing pipe structure and toilet to solve the problem of many dead corners in the open water channel of the toilet for flushing and cleaning.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a flushing pipe structure, including an inlet pipe and a flushing pipe. An inlet channel is formed in the inlet pipe, and an inlet and a first outlet are formed on the inlet pipe that connect to the inlet channel. A flushing trough is formed in the flushing pipe, and the opening of the flushing trough is opened on one side of the flushing pipe. The flushing trough is connected to the inlet channel through the first outlet. A flow guide is provided in the flushing trough, and the flow guide is used to guide the water flow to the top wall of the flushing trough.

[0007] In one embodiment, the guide portion is a protrusion located on the side of the flushing tank near the opening.

[0008] In one embodiment, the top wall of the flushing tank near the opening protrudes beyond the bottom wall of the flushing tank near the opening.

[0009] In one embodiment, the angle between the line connecting the bottom wall of the flushing tank near the opening and the top wall of the flushing tank near the opening and the horizontal plane is α, where 45°≤α≤60°.

[0010] In one embodiment, one inlet pipe is provided, and the dimensions of the flushing tank along the height direction gradually decrease from one end connected to the inlet pipe to the other end.

[0011] In one embodiment, the lowest point of the inlet is lower than the lowest point of the first outlet.

[0012] In one embodiment, the height difference between the axis of the inlet and the axis of the first outlet is between 40mm and 60mm.

[0013] In one embodiment, the inlet pipe further includes a second outlet connected to the inlet channel, wherein the effective flow area of ​​the second outlet is smaller than the effective flow area of ​​the first outlet.

[0014] In one embodiment, the lowest point of the inlet is lower than the lowest point of the second outlet.

[0015] Secondly, this utility model provides a toilet bowl, including a liner and a flushing pipe structure as described in any of the above claims, wherein the flushing pipe is disposed above the liner and is used to flush the surface of the liner.

[0016] The beneficial effects of this utility model are as follows: The above-mentioned flushing pipe structure has a guide section in the flushing pipe. The water entering the flushing pipe from the inlet pipe will not flow downwards to flush the surface of the inner pot immediately. Instead, it will spread upwards under the guidance of the guide section, wash the top wall of the flushing tank, and then flush the surface of the pot downwards. This expands the flushing range of the flushing pipe structure and reduces the cleaning dead corners of the toilet. Attached Figure Description

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 6As shown, this utility model provides a flushing pipe structure 10 and a toilet in its embodiment. The toilet can be a squat toilet or a seated toilet, and it can be a toilet with a water sump or a toilet without a water sump. The toilet includes a liner 20 and the aforementioned flushing pipe structure 10. The liner 20 has an opening at the top and a drain outlet at the bottom. The flushing pipe structure 10 is disposed on the liner 20. The flushing pipe structure 10 includes an inlet pipe 1 and a flushing pipe 2. An inlet channel 14 is formed inside the inlet pipe 1, and an inlet 11 for connecting an external water source to the inlet channel 14 is also formed on the inlet pipe 1. The external water source can come from a water tank or an external water supply pipe. Meanwhile, the inlet pipe... 1 also has a first outlet 12 that connects to the inlet channel 14. The flushing pipe 2 is arranged above the inner tank 20 and surrounds the inner tank 20, that is, the flushing pipe 2 is arranged in a ring. A flushing trough 21 is formed inside the flushing pipe 2. The opening of the flushing trough 21 is arranged on one side of the ring of the flushing pipe 2. The flushing trough 21 is connected to the inlet channel 14 through the first outlet 12. A guide part 22 is provided inside the flushing trough 21. The guide part 22 is used to guide the water flow to the top wall of the flushing trough 21.

[0032] The aforementioned flushing pipe structure 10 has a guide section 22 inside the flushing pipe 2. Water entering the flushing pipe 2 from the inlet pipe 1 will not flow downwards and flush the surface of the inner pot 20 immediately. Instead, it will spread upwards under the guidance of the guide section 22, washing the top wall of the flushing tank 21 before flushing the surface of the pot downwards. This expands the flushing range of the flushing pipe structure 10 and reduces the cleaning dead corners of the toilet.

[0033] Specifically, both the flushing pipe 2 and the inner pot 20 can be made of ceramic. Therefore, the flushing pipe 2 can be molded separately or integrally molded with the inner pot 20. In the current embodiment, to simplify the toilet manufacturing process, the flushing pipe 2 and the inner pot 20 are integrally molded. Specifically, the flushing pipe 2 and the inner pot 20 have a smooth transition on the pot surface to prevent the water flow from the flushing tank 21 to the pot surface from being blocked, thus affecting the flushing effect on the pot surface.

[0034] The inlet pipe 1 can also be made of ceramic and integrally formed with the flushing pipe 2 and the inner pot 20. There can be one or two inlet pipes 1. When there is only one inlet pipe 1, it is located at the rear end of the inner pot 20. The water flow in the flushing pipe 2 is concentrated at the drain outlet, providing stronger impediment to larger debris and reducing the likelihood of blockage. When there are two inlet pipes 1, they are located at the front and rear ends of the inner pot 20 respectively and connected to the flushing pipe 2 to form a ring structure. The water flow in the flushing pipe 2 can fully cover the surface of the inner pot 20, and due to the reduced water flow path and lower kinetic energy loss, the flushing effect on the inner pot 20 is better. It can be understood that the "rear end" of the inner pot 20 refers to the end facing the back of the user when the toilet is in normal use; the end facing the front is the "front."

[0035] Furthermore, when only one inlet pipe 1 is provided, the dimensions of the flushing trough 21 along the height direction gradually decrease from one end connected to the inlet pipe 1 to the other end, so that even if kinetic energy is lost during the flow, the flow velocity can be kept as constant as possible, thereby ensuring that the water flow has a good impact effect on the pot surface and the wall of the flushing trough 21 along the length direction; when two inlet pipes 1 are provided, the dimensions of the flushing trough 21 along the height direction can remain unchanged.

[0036] Based on the typical dimensions of a toilet, in this embodiment, the flushing trough 21 is set to a height dimension of 15-20mm, and the depth of the flushing trough 21 is also set to a depth of 15-20mm.

[0037] In some embodiments, the guide portion 22 is a protrusion located on the side of the flushing tank 21 near the opening. The protrusion changes the direction of water flow in the flushing tank 21, causing the water to impact the top wall of the flushing tank 21 and then rinse the pot surface downwards after rinsing the top wall of the flushing tank 21. Specifically, the protrusion transitions to the bottom wall of the flushing tank 21 with an arc to reduce the possibility of scale or other impurities accumulating.

[0038] Specifically, the height of the protrusion is set between 5-8mm. If the height is too high, the opening of the flushing tank 21 will be too small; if the height is too low, it will not be able to block the water flow.

[0039] In other embodiments, the guide portion 22 is a guide surface provided on the bottom wall of the flushing pipe 2. The guide surface extends upward at an angle gradually approaching the groove opening, so as to guide the water flow to the top wall of the flushing pipe 2.

[0040] refer to Figure 3As shown, to prevent water from splashing out of the flushing trough 21 and splashing out of the toilet bowl, the top wall of the flushing trough 21 near the opening protrudes beyond the bottom wall near the opening. Specifically, let α be the angle between the line connecting the bottom wall of the flushing trough 21 near the opening and the top wall of the flushing trough 21 near the opening and the horizontal plane, where 45°≤α≤60°. If α is too large, the inlet formed by the surrounding flushing pipe 2 will be too small, easily affecting the entry of excrement into the bowl; if α is too small, the blocking effect on the water flow will be poor. Understandably, this design also conceals the flushing trough 21, improving the aesthetics of the toilet.

[0041] More specifically, the inner wall of the flushing pipe 2 above the flushing trough 21 slopes upwards and extends outwards to further increase the inlet area formed by the surrounding flushing pipe 2, reducing the difficulty for excrement to enter the toilet bowl. Given that the toilet is a squat toilet, a footrest area 23 is formed on the upper surface of the flushing pipe 2. The footrest area 23 is provided with anti-slip texture to increase the friction between the user's shoes and the flushing pipe 2, reducing the possibility of the user falling.

[0042] refer to Figure 6 As shown, in order to further accelerate the flushing speed, first water outlets 12 are provided at both ends of the inlet pipe 1. After the water flows from the inlet pipe 1 into the flushing tank 21 of the flushing pipe 2, it is divided into two streams.

[0043] Taking the inlet pipe 1 located at the rear end of the boiler 20 as an example, in order to further flush the rear end of the boiler surface of the boiler 20, the inlet pipe 1 also includes a second outlet 13 connected to the inlet channel 14. The second outlet 13 connects to the inner cavity of the boiler 20, and water in the inlet channel 14 can flow out through the second outlet 13 to flush the rear end of the boiler surface of the boiler 20. It is worth noting that the effective flow area of ​​the second outlet 13 is smaller than that of the first outlet 12 to prevent water from flowing only out of the second outlet 13 without flowing to the first outlet 12. Of course, the second outlet 13 can also be provided for the inlet pipe 1 located at the front end of the boiler 20, which will not be described in detail here.

[0044] For example, multiple second outlets 13 are provided at intervals along the left and right direction on the inlet pipe 1 to further expand the flushing range.

[0045] refer to Figure 5As shown, the lowest point of the inlet 11 is lower than the lowest point of the outlet (including the first outlet 12 and the second outlet 13), allowing some water to accumulate in the inlet channel 14. When water flows from the inlet 11 into the inlet pipe 1, the water in the inlet channel 14 rises and flows from the first outlet 12 to the flushing tank 21. During this process, the water flowing in from the inlet 11 is first delayed by the accumulated water in the inlet channel 14, reducing the flow rate. As the water level in the inlet channel 14 rises, it slowly squeezes out the air in the inlet channel 14, preventing air from accumulating in the upper part of the inlet channel 14 and effectively reducing the noise of air blasting during flushing.

[0046] In some embodiments, the highest point of the inlet 11 is not higher than the lowest point of the first outlet 12, so that the water entering the inlet channel 14 through the inlet 11 does not directly contact the air, further reducing noise. Specifically, the height difference between the axis of the inlet 11 and the axis of the first outlet 12 is between 40mm and 60mm. If the height difference is too large, the volume of the inlet pipe 1 will be large, and the manufacturing cost will be high; if the height difference is too small, the noise reduction effect will be poor.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
