Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, in particular to a toilet. Background Art

[0002] Toilets, also known as toilets, are divided into drop-type and siphon-type according to the sewage discharge method. The drop-type uses the gravity of flushing water to discharge waste, and only positive pressure is formed during the flushing and sewage discharge process, without negative pressure. The siphon-type uses a certain pressure (siphon phenomenon) formed after the flushing water fills the sewage pipe to discharge waste, and is a push-type structure.

[0003] To achieve the same flushing effect, the water consumption of a drop-type toilet is 8L, and the water consumption of a siphon toilet can be reduced to 5L. However, reducing the amount of water used in a single flush of a toilet is always a technical problem that needs to be continuously improved and a technical effect that is pursued in this technical field.

[0004] Therefore, a new toilet flushing method is urgently needed to achieve more water-saving and energy-saving effects.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: The present invention provides a toilet, comprising: A main body, in which a toilet cavity and a mounting cavity are formed, wherein the toilet cavity has a flushing inlet and a flushing outlet; A flushing pipeline is arranged in the installation cavity and communicated with the flushing inlet for flushing water into the toilet cavity; A sewage pipe is arranged in the installation cavity and communicated with the flushing outlet for discharging waste in the toilet bowl cavity, a first water seal area is formed at the communication position between the sewage pipe and the flushing outlet, and a second water seal area is formed in the sewage pipe; A water tank is arranged in the installation cavity and is located beside the sewage pipe. The water tank is connected to the flushing pipeline and is used to supply water to the flushing pipeline. A ventilation pipeline is connected between the water tank and the sewage pipe. The connection position between the ventilation pipeline and the water tank is higher than the upper water storage limit of the water tank. The connection position between the ventilation pipeline and the sewage pipe is located on the pipeline between the first water seal area and the second water seal area.

[0008] In some embodiments of the present application, the connecting position between the ventilation pipeline and the sewage pipe is located at the top of the sewage pipe.

[0009] In some embodiments of the present application, the sewage pipe includes a sewage pipe section 1, a sewage pipe section 2, a sewage pipe section 3, and a sewage pipe section 4 that are connected in sequence, the sewage pipe section 1 extends obliquely upward from the flushing outlet, the sewage pipe section 2 extends downward from the top of the sewage pipe section 1, the sewage pipe section 3 extends obliquely upward from the bottom of the sewage pipe section 2 toward the direction close to the sewage pipe section 1, and the sewage pipe section 4 extends downward from the top of the sewage pipe section 3; One end of the ventilation pipeline is arranged at the connecting position between the first section of the sewage pipe and the second section of the sewage pipe.

[0010] In some embodiments of the present application, the installation cavity includes a first installation cavity and a second installation cavity that are connected, the first installation cavity is located behind the toilet cavity, and the second installation cavity surrounds the toilet cavity; The sewage pipe is arranged in the first installation cavity, a part of the water tank is located in the first installation cavity, and another part of the water tank extends into the second installation cavity.

[0011] In some embodiments of the present application, the water tank is disposed close to one side of the installation cavity; The water tank is provided with a first pipe joint and a second pipe joint on the side wall facing the sewage pipe, and a third pipe joint is provided on the front side wall of the water tank; The first pipe joint is connected to the ventilation pipeline, the second pipe joint is connected to the water inlet pipeline, and the third pipe joint is connected to the flushing pipeline.

[0012] In some embodiments of the present application, the water tank is provided with a mounting groove on the side wall facing the sewage pipe, the mounting groove is arranged close to the bottom of the water tank, and the second pipe joint is arranged at the mounting groove.

[0013] In some embodiments of the present application, the flushing pipeline includes a main flushing pipeline, a first flushing branch pipeline, and a second flushing branch pipeline. The main flushing pipeline is provided with a water pump. The main flushing pipeline, the first flushing branch pipeline, and the second flushing branch pipeline are connected through a water diversion valve.

The setting of the ventilation pipeline makes the siphon in the sewage pipe a dual-power structure of "pushing forward and pulling back" for the water and sewage in the toilet bowl cavity, thereby greatly reducing the water consumption while achieving the same sewage discharge effect.

[0018] When the water level in the water tank reaches the upper water storage limit, since the connection position between the ventilation pipeline and the water tank is higher than the upper water storage limit of the water tank, the water in the water tank can be effectively prevented from flowing into the sewage pipe through the ventilation pipeline.

[0019] The water tank is arranged beside the sewage pipe, and the water tank and the sewage pipe are arranged on the left and right, making full use of the installation cavity behind the toilet bowl cavity. The internal structure of the toilet is compact and small in size.

In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0029] This embodiment discloses a toilet, referring to Figures 1 to 8 The water pump comprises a main body 100, a sewage pipe 200, a flushing pipe 400, a ventilation pipe 500, a water tank 300 and the like.

[0030] The main body 100 is a ceramic structure, in which a toilet chamber 110 and an installation chamber 120 are formed. The installation chamber 120 is used to install a sewage pipe 200, a flushing pipe 400, a ventilation pipe 500, a water tank 300, etc. The overall structure of the toilet is compact, small in size, and occupies little space. Figure 6 2 is a schematic longitudinal cross-sectional view of the main body 100 .

[0031] The toilet chamber 110 has a flushing water inlet and a flushing water outlet 114. Flushing water for sewage discharge flows into the toilet chamber 110 from the flushing water inlet to flush the waste in the toilet chamber 110, and the waste in the toilet chamber 110 is discharged from the flushing water outlet 114 under the action of the water flow.

[0032] The flushing pipe 400 is disposed in the installation cavity 120, and the flushing pipe 400 is connected to the flushing inlet for flushing water into the toilet cavity 110. The flushing inlet can be disposed at multiple locations so that the flushing pipe 400 can flush water to multiple locations of the toilet cavity 110 at the same time, thereby improving the sewage discharge effect.

[0033] The sewage pipe 200 is disposed in the installation cavity 120 , and the sewage pipe 200 is connected to the flushing outlet 114 for discharging waste in the toilet cavity 110 .

[0034] A first water seal area 210 is formed at the connection position between the sewage pipe 200 and the flushing outlet 114, and a second water seal area 220 is formed in the sewage pipe 200. Figure 3 The sewage pipe 200 forms a double water seal structure through its own bending structure, which effectively prevents the odor from overflowing.

[0035] The water tank 300 is disposed in the installation cavity 120 and is located beside the sewage pipe 200 . The water tank 300 is communicated with the flushing pipe 400 to supply water to the flushing pipe 400 .

[0036] The ventilation pipe 500 is connected between the water tank 300 and the sewage pipe 200. The connection position between the ventilation pipe 500 and the water tank 300 is higher than the upper water storage limit 380 of the water tank 300. The connection position between the ventilation pipe 500 and the sewage pipe 200 is located on the pipe between the first water seal area 210 and the second water seal area 220.

[0037] During sewage discharge, the water tank 300 supplies water to the flushing pipe 400, and the water in the water tank 300 flows into the toilet chamber 110 through the flushing pipe 400 and the flushing inlet to flush the dirt in the toilet chamber 110. During this process, the water level in the water tank 300 continues to drop, and a negative pressure is formed in the upper space of the water tank 300. Under the action of the negative pressure, the air in the pipe between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipe 500, so that a negative pressure is also formed in the pipe between the first water seal area 210 and the second water seal area 220, thereby forming a pulling force in front of the first water seal area 210 (along the water flow direction), sucking the water in the toilet chamber 110 and increasing the water flow rate. In this way, there are two driving forces for the water and waste in the toilet bowl cavity 110 to be discharged outward along the sewage pipe 200. One driving force is the flushing power of water flowing into the toilet bowl cavity 110 from the flushing pipe 400 and the flushing inlet, and the other driving force is the water absorption power of the water in the toilet bowl cavity 110 formed by the air in the pipe between the first water seal area 210 and the second water seal area 220 flowing into the water tank 300 through the ventilation pipe 500, thereby absorbing the water in the toilet bowl cavity 110, thereby making the flushing and sewage discharge speed faster and achieving a better sewage discharge effect with the least amount of water.

[0038] This toilet adopts a dual-power siphon type sewage discharge method. The setting of the ventilation pipe 500 makes the siphon in the sewage pipe 200 become a dual-power structure of "pushing forward and pulling back" for the water and sewage in the toilet chamber 110, thereby greatly reducing the water consumption while achieving the same sewage discharge effect.

[0039] When the water level in the water tank 300 reaches the upper water storage limit 380, since the connection position between the ventilation pipe 500 and the water tank 300 is higher than the upper water storage limit 380 of the water tank 300, the water in the water tank 300 can be effectively prevented from flowing into the sewage pipe 200 through the ventilation pipe 500.

[0040] There is a certain distance between the water storage upper limit 380 of the water tank 300 and the top of the water tank 300 , which is equivalent to reserving an air-filled space at the top of the water tank 300 , and one end of the ventilation pipeline 500 is connected to the air-filled space.

[0041] The water tank 300 is disposed beside the sewage pipe 200, and the water tank 300 and the sewage pipe 200 are arranged on the left and right, making full use of the installation cavity 120 behind the toilet cavity 110, and the internal structure of the toilet is compact and small in size.

[0042] In some embodiments of the present application, refer to Figure 7 The communication position between the ventilation pipeline 500 and the sewage pipe 200 is located at the top of the sewage pipe 200. When the sewage is discharged along the sewage pipe 200, it can effectively prevent the sewage from flowing back into the water tank 300 along the ventilation pipeline 500.

[0043] In some embodiments of the present application, refer to Figure 3 and Figure 7 The sewage pipe 200 includes a sewage pipe section 1 231, a sewage pipe section 232, a sewage pipe section 3 233, and a sewage pipe section 4 234 which are connected in sequence. The sewage pipe section 1 231 extends obliquely upward from the flushing outlet 114, the sewage pipe section 232 extends downward from the top of the sewage pipe section 1 231, the sewage pipe section 3 233 extends obliquely upward from the bottom of the sewage pipe section 232 toward the direction close to the sewage pipe section 1 231, and the sewage pipe section 4 234 extends downward from the top of the sewage pipe section 3 233. The sewage pipe 200 is generally in a ∽-shaped structure.

[0044] A first water seal area 210 is formed at a connection position between the first sewage pipe section 231 and the flushing outlet 114 , and a second water seal area 220 is formed at a connection position between the second sewage pipe section 232 and the third sewage pipe section 233 .

[0045] One end of the ventilation pipe 500 is arranged at the connecting position between the sewage pipe section 1 231 and the sewage pipe section 232, so that the ventilation pipe 500 is located at the top of the sewage pipe 200 to prevent sewage from flowing back into the ventilation pipe 500 during sewage discharge.

[0046] In some embodiments of the present application, refer to Figure 6 The installation cavity 120 includes a first installation cavity 121 and a second installation cavity 122 which are connected to each other. The first installation cavity 121 is located behind the toilet cavity 110, and the second installation cavity 122 surrounds the toilet cavity 110. Specifically, the first installation cavity 121 is a large space located behind the toilet cavity 110, and the second installation cavity 122 is a small space surrounding the outer periphery of the toilet cavity 110.

[0047] The sewage pipe 200 is arranged in the first installation cavity 121, occupying most of the space of the installation cavity 120. How to reasonably arrange components such as the water tank 300, the flushing pipe 400, and the ventilation pipe 500 in a limited space is an area where the toilet needs to be improved.

[0048] In this embodiment, refer to Figure 4 and Figure 5 The water tank 300 is arranged close to one side of the installation cavity 120, a part of the water tank 300 is located in the first installation cavity 121, and the other part of the water tank 300 extends into the second installation cavity 122. The water tank 300 as a whole is a vertical flat structure, that is, the width of the water tank 300 is narrow to make full use of the narrow space between the sewage pipe 200 and the side wall of the main body 100. By lengthening the length of the water tank 300 and extending the front part of the water tank 300 into the second installation cavity 122, not only can the narrow space on the outer peripheral side of the toilet cavity 110 be fully utilized, but also the volume of the water tank 300 can be guaranteed, and the sewage flushing water volume can be guaranteed.

[0049] In some embodiments of the present application, refer to Figure 7 and Figure 8 The water tank 300 is provided with a first pipe joint 310 and a second pipe joint 320 on the side wall facing the sewage pipe 200 , and a third pipe joint 330 is provided on the front end side wall of the water tank 300 .

[0050] The first pipe joint 310 is connected to the ventilation pipeline 500, the second pipe joint 320 is connected to the water inlet pipeline, and the third pipe joint 330 is connected to the flushing pipeline 400. A water inlet solenoid valve 340 is provided at the water inlet pipeline to control the on and off of the water inlet.

[0051] Since the water tank 300 is arranged close to one side of the installation cavity 120, that is, the water tank 300 is arranged close to one side wall of the main body 100, the gap between the water tank 300 and the side wall of the main body 100 is small, and it is not easy to run pipes. Therefore, the first pipe joint 310 and the second pipe joint 320 are arranged on the side of the water tank 300 facing the sewage pipe 200 to facilitate pipe running.

[0052] The first pipe joint 310 is disposed at a position on the upper rear side of the water tank 300. Figure 7 It can be seen that the second section 232 of the sewage pipe extends obliquely downward so that the upper rear portion of the water tank 300 is not blocked by the second section 232 of the sewage pipe, and the ventilation line 500 extends along the upper portion of the second section 232 of the sewage pipe to be connected to the first pipe joint 310.

[0053] The third pipe joint 330 is arranged on the front end side wall of the water tank 300, so that the flushing pipe 400 is located beside the toilet cavity 110 and in front of the water tank 300. The flushing pipe 400 is equivalent to being located in the second installation cavity 122, making full use of the narrow space around the toilet cavity 110, further improving the compactness of the structure. At the same time, the front end of the water tank 300 is also closer to the toilet cavity 110, which also helps to reduce the length of the flushing pipe 400.

[0054] In some embodiments of the present application, refer to Figure 7 and Figure 8The water tank 300 is provided with a mounting groove 370 on the side wall facing the sewage pipe 200. The mounting groove 370 is arranged near the bottom of the water tank 300. The second pipe joint 320 is arranged at the mounting groove 370. The second pipe joint 320 is provided with a water inlet solenoid valve 340, and the water inlet solenoid valve 340 is connected to the water inlet pipeline. The water inlet solenoid valve 340 has a certain volume. The setting of the mounting groove 370 provides an installation space for the water inlet solenoid valve 340 to avoid interference between the water inlet solenoid valve 340 and the sewage pipe 200 on the side.

[0055] In some embodiments of the present application, refer to Figure 8 The outer contour of the water tank 300 is divided into a first part 350 and a second part 360 along its length direction. The height of the first part 350 is greater than the height of the second part 360. The first part 350 is located in the first installation cavity 121, and the second part 360 extends into the second installation cavity 122.

[0056] That is to say, the outer contour of the water tank 300 is shorter in the front and higher in the back along its length direction, and the second portion 360 which is shorter in the front is convenient for extending into the second installation cavity 122 with a narrow peripheral space of the toilet cavity 110 .

[0057] In some embodiments of the present application, refer to Figure 7 The flushing pipeline 400 includes a flushing main pipeline 410, a first flushing branch pipeline 420, and a second flushing branch pipeline 430. A water pump 450 is provided on the flushing main pipeline 410. The flushing main pipeline 410, the first flushing branch pipeline 420, and the second flushing branch pipeline 430 are connected through a water diversion valve 440.

[0058] The flushing main line 410 is in communication with the water tank 300 . Specifically, the flushing main line 410 is connected to the third pipe joint 330 at the front end of the water tank 300 .

[0059] Reference Figure 6 A sewage inlet chamber 113 and a first flushing water inlet 111 communicating with the sewage inlet chamber 113 are provided at the bottom of the toilet chamber 110 . A flushing water outlet 114 is communicated with the sewage inlet chamber 113 . The first flushing water inlet 111 and the flushing water outlet 114 are arranged opposite to each other.

[0060] A water guide groove 115 is provided at the top of the toilet chamber 110 along its circumferential direction, and a second flushing water inlet 112 communicating with the water guide groove 115 is provided at the top of the toilet chamber 110 .

[0061] The first flushing water branch pipe 420 is in communication with the first flushing water inlet 111 , and the second flushing water branch pipe 430 is in communication with the second flushing water inlet 112 .

[0062] When flushing the toilet, the water pump 450 is turned on, and the water in the water tank 300 flows into the first flush branch pipe 420 and the second flush branch pipe 430 through the flush main pipe 410 and the water diverter valve 440. The water in the second flush branch pipe 430 flows out from the second flush inlet 112. During the flow along the water guide groove 115, the water flows along the inner circumferential wall of the toilet chamber 110 to the sewage inlet chamber 113 to flush the dirt in the toilet chamber 110. The water in the first flush branch pipe 420 is flushed into the sewage inlet chamber 113 from the first flush inlet 111, pushing the dirt in the sewage inlet chamber 113 to the flush outlet 114, and flows into the sewage pipe 200 to discharge the dirt.

[0063] In some embodiments of the present application, the amount of water entering the first flush branch pipe 420 from the main flush pipe 410 is less than the amount of water entering the second flush branch pipe 430, so that more water flows downward from the top of the toilet chamber 110, thereby improving the sewage flushing effect of the toilet chamber 110 and helping to reduce water consumption.

[0064] There are two driving forces for the flow of sewage in the sewage inlet chamber 113 into the sewage discharge pipe 200. One driving force is the flushing power flowing out from the first flushing inlet 111, which flushes the sewage in the sewage inlet chamber 113 into the sewage discharge pipe 200. The other driving force is that the air in the pipe between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipe 500, and a negative pressure is formed in the pipe between the first water seal area 210 and the second water seal area 220 to absorb water and sewage in the sewage inlet chamber 113. The water absorption power makes the flushing and sewage discharge speed faster and achieves a better sewage discharge effect with the least amount of water.

[0065] It is precisely because the siphon in the sewage pipe 200 can achieve a dual-power effect of "pushing forward and pulling backward" on the water and waste in the toilet chamber 110, so the amount of water distributed into the first flushing branch pipe 420 through the water diverter valve 440 does not need to be large, so that more water can flow into the second flushing branch pipe 430, and more water flows downward from the top of the toilet chamber 110, thereby improving the sewage flushing effect of the toilet chamber 110 and achieving the effect of reducing water consumption.

[0066] In some embodiments of the present application, a liquid level sensor 600 is provided in the water tank 300 for detecting the amount of water in the water tank 300 .

[0067] When the toilet receives a flush signal, the water pump 450 is turned on, and the water tank 300 supplies water to the flush pipe 400. One water path is sprayed into the sewage inlet chamber 113 through the first flush branch pipe 420 and the first flush inlet 111 to spray and flush the water and sewage in the sewage inlet chamber 113. The other water path flows into the circumferential water guide groove 115 on the top of the toilet chamber 110 through the second flush branch pipe 430 and the second flush inlet 112, and flows to the sewage inlet chamber 113 along the inner wall of the toilet chamber 110 to flush the sewage in the toilet chamber 110. At the same time, the water level in the water tank 300 continues to drop. The water in the upper space of the water tank 300 is reduced, and negative pressure is formed in the upper space of the water tank 300. Under the action of the negative pressure, the air in the pipe between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipe 500, so that negative pressure is also formed in the pipe between the first water seal area 210 and the second water seal area 220, thereby forming a pulling force in front of the first water seal area 210 (along the water flow direction), sucking the water and dirt in the sewage inlet chamber 113, and the water and dirt in the sewage inlet chamber 113 are discharged from the sewage pipe 200 under the dual action of the flushing power and the negative pressure suction power; When the liquid level sensor 600 detects that the water level in the water tank 300 drops to the first position, the water pump 450 stops, the water tank 300 stops supplying water to the flushing pipe 400, and the water inlet pipe starts to replenish water into the water tank 300 until the liquid level sensor 600 detects that the water level in the water tank 300 rises to the upper water storage limit 380 and stops replenishing water.

[0068] When the water tank 300 is replenished with water, the water level in the water tank 300 continues to rise, and the air at the top of the water tank 300 flows into the pipeline between the first water seal area 210 and the second water seal area 220 through the ventilation pipeline 500.

[0069] In some embodiments of the present application, the toilet has a cover body 710 and a cover body seat 720, the cover body 710 is rotatably connected to the cover body seat 720, the cover body 710 is used to open or close the bottom opening of the toilet cavity 110, and the cover body seat 720 closes the top opening of the first installation cavity 121.

[0070] Since the sewage pipe 200, the water tank 300 and other components are installed in the installation cavity 120 and are not exposed, the overall thickness of the cover seat 720 is relatively thin.

[0071] In some embodiments of the present application, the toilet is a smart toilet, and the cover 710 is a smart toilet cover, which integrates functions such as flushing, drying, and automatic flipping.

[0072] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0073] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
