Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sanitary ware, and 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 single flushing volume of a toilet is always a technical problem that needs to be continuously improved and a technical effect 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.

[0011] 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, the first flushing branch pipeline, and the second flushing branch pipeline are connected through a water diversion valve. The water diversion valve has a closed state to cut off the connection between the main flushing pipeline and the first flushing branch pipeline and the second flushing branch pipeline. The water diversion valve has an open state to connect the main flushing pipeline, the first flushing branch pipeline, and the second flushing branch pipeline. The main flushing pipeline is connected to the bottom of the water tank; The bottom of the toilet chamber is provided with a sewage inlet chamber and a first flushing water inlet communicating with the sewage inlet chamber, and the flushing water outlet is communicated with the sewage inlet chamber; A water guide groove is provided on the top of the toilet chamber along its circumferential direction, and a second flushing inlet connected to the water guide groove is provided on the top of the toilet chamber; The first flushing water branch pipeline is in communication with the first flushing water inlet, and the second flushing water branch pipeline is in communication with the second flushing water inlet.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are: The toilet disclosed in the present application is a dual-power siphon type sewage discharge method. 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 above the sewage pipe and the flushing pipe. The water tank and the upper limit of the sewage pipe are arranged. The water in the water tank flows into the flushing pipe under the action of gravity. The water pump is eliminated, which helps to reduce product costs and flushing reliability.

[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, and a toilet chamber 110 and an installation chamber 120 are formed therein. 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 5 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 bowl 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 above the sewage pipe 200 . The water tank 300 is communicated with the flushing pipe 400 to supply water to the flushing pipe 400 .
[0036] There is a distance between the water storage upper limit of the water tank 300 and the top of the water tank 300 to form an air-filled space.
[0037] The ventilation pipe 500 is connected between the water tank 300 and the sewage pipe 200, and the ventilation pipe 500 is connected to the air filling space. That is, the connection position of the ventilation pipe 500 and the water tank 300 is higher than the upper water storage limit of the water tank 300, and the connection position of 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.
[0038] During sewage discharge, the water tank 300 supplies water to the flushing pipe 400. Since the water tank 300 is located above the sewage pipe 200 and the flushing pipe 400, the water in the water tank 300 flows into the toilet chamber 110 through the flushing pipe 400 and the flushing inlet under the action of gravity, and the dirt in the toilet chamber 110 is flushed. In 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.
[0039] The toilet uses a dual-power siphon type sewage discharge method. The setting of the ventilation pipeline 500 makes the siphon in the sewage pipe 200 become a dual-power structure of "pushing forward and pulling backward" for the water and sewage in the toilet chamber 110, thereby greatly reducing the water consumption while achieving the same sewage discharge effect.
[0040] When the water level in the water tank 300 reaches the upper water storage limit, since the connection position between the ventilation pipe 500 and the water tank 300 is higher than the upper water storage limit 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.
[0041] There is a certain distance between the upper water storage limit 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.
[0042] The water tank 300 is disposed above the sewage pipe 200 and the flushing pipeline 400. The water tank 300 and the sewage pipe 200 are arranged up and down. The water in the water tank 300 flows into the flushing pipeline 400 under the action of gravity. The water pump is eliminated, which helps to reduce product costs and flushing reliability.
[0043] Since the water pump is eliminated, a control valve is provided in the flushing pipeline 400 to control the on-off of the flushing pipeline 400. When flushing, the control valve is opened, and the water in the water tank 300 flows into the toilet chamber 110 through the flushing pipeline 400 under the action of gravity. When not flushing, the control valve is closed.
[0044] A liquid level sensor 600 is provided in the water tank 300 for detecting the amount of water in the water tank 300 .
[0045] When the toilet receives a flushing signal, the control valve in the flushing pipe 400 opens, and the water in the water tank 300 flows into the toilet chamber 110 through the flushing pipe 400 under the action of gravity, and the dirt in the toilet chamber 110 is flushed. At the same time, the water level in the water tank 300 continues to drop, and negative pressure is formed in the upper space of the inner cavity 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 toilet chamber 110, and the water and dirt in the toilet chamber 110 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 solenoid valve in the flushing pipe 400 is closed, the flushing pipe 400 is cut off, the flushing of the toilet chamber 110 is stopped, and the water inlet pipe 840 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 limit of the water storage, and then stops replenishing water. The water inlet pipe 840 is provided with a water inlet solenoid valve 360 to control the on and off of the water inlet.
[0046] 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.
[0047] In some embodiments of the present application, refer to Figure 8 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.
[0048] In some embodiments of the present application, refer to Figure 3 and Figure 8The 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.
[0049] 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 .
[0050] 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.
[0051] In some embodiments of the present application, refer to Fig.10 A clearance groove 330 is provided at the bottom of the water tank 300 , the top of the sewage pipe 200 is directly opposite to the clearance groove 330 , and the ventilation pipeline 500 passes through the clearance groove 330 .
[0052] Since the water tank 300 is located above the sewage pipe 200, the setting of the clearance groove 330 fully utilizes the gap between the water tank 300 and the sewage pipe 200. The clearance groove 330 provides space for the ventilation pipe 500 to run, thereby improving the compactness of the layout of the water tank 300, the sewage pipe and the ventilation pipe 500 in the upper and lower directions, and also plays a certain limiting role on the ventilation pipe 500.
[0053] 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. The flushing main pipeline 410, the first flushing branch pipeline 420, and the second flushing branch pipeline 430 are connected through a water diverter valve 440. The water diverter valve 440 is the control valve in the flushing pipeline 400 described above. The water diverter valve 440 has a closing function. The water diverter valve 440 has a closed state to cut off the connection between the flushing main pipeline 410 and the first flushing branch pipeline 420 and the second flushing branch pipeline 430, and the water diverter valve 440 has an open state to connect the flushing main pipeline 410, the first flushing branch pipeline 420, and the second flushing branch pipeline 430.
[0054] The flushing main line 410 is in communication with the water tank 300. Specifically, the flushing main line 410 is connected to the bottom of the water tank 300 to fully utilize gravity to achieve flushing.
[0055] Reference Figure 5 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.
[0056] 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 .
[0057] 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 .
[0058] When flushing the toilet, the water diverter valve 440 changes from a closed state to an open state, 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 process of flowing along the water guide groove 115, the water flows along the inner peripheral wall of the toilet chamber 110 to the sewage inlet chamber 113 to flush the sewage 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 sewage in the sewage inlet chamber 113 to the flush outlet 114, and flows into the sewage pipe 200 to discharge the sewage. At the same time, the water level in the water tank 300 continues to drop, and negative pressure is formed in the upper space of the inner cavity 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 diversion valve 440 changes from an open state to a closed state, the water tank 300 stops supplying water to the flushing pipe 400, and the water inlet pipe 840 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 limit of the water storage and stops replenishing water.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] In some embodiments of the present application, refer to Figure 7 and Fig.10 The flushing pipeline 400 is located beside the sewage pipe 200 and below the water tank 300. A control unit 900 is provided at the bottom of the water tank 300. The control unit 900 is located at another opposite side of the sewage pipe 200. The control unit 900 is used to control the opening and closing of the flushing related control valves.
[0063] The flushing pipe 400 is arranged beside the sewage pipe 200, and the gap between the sewage pipe 200 and the inner wall of the main body 100 is fully utilized to improve the compactness of the structure. The control unit 900 is arranged on the other side, and the gap between the sewage pipe 200 and the other opposite inner wall of the main body 100 is fully utilized. In addition, the flushing pipe 400 and the control unit 900 are arranged relatively separately to avoid damage to the control unit 900 when the flushing pipe 400 has a fault such as leakage.
[0064] In some embodiments of the present application, refer to Figure 6 and Figure 7 The toilet bowl includes a cleaning and heating assembly 800, which includes a cleaning solenoid valve 810, a cleaning heater 820, and a cleaning water outlet 830 connected in sequence. A cleaning water pump 850 provides power for the water flow in the cleaning and heating assembly 800.
[0065] When the cleaning button is pressed, water starts to flow into the cleaning solenoid valve 810. The water source of the cleaning solenoid valve 810 is independent and filtered in advance. The water enters the cleaning heater 820 for heating. According to the temperature control instruction of the control unit 900, the water is heated to a suitable temperature and then enters the cleaning water outlet 830 and flows out.
[0066] The cleaning solenoid valve 810 and the cleaning heater 820 are arranged at the bottom of the water tank 300 , and are arranged on different sides from the control unit 900 , so as to fully utilize the installation space at the bottom of the water tank 300 .
[0067] The water tank 300 in this embodiment not only serves as a water storage device, but also serves as an installation carrier for the control unit 900 and the cleaning and heating component 800.
[0068] The water tank 300 is provided with a pipe outlet 340 which passes through from top to bottom. A mounting seat 350 is provided on the upper part of the water tank 300. The cleaning water outlet 830 is arranged on the mounting seat 350. The water pipe 840 between the cleaning water outlet 830 and the cleaning heater 820 passes through the pipe outlet 340 to facilitate pipe routing.
[0069] In some embodiments of the present application, refer to Fig. 9 and Fig.11 The water tank 300 includes an upper shell 310 and a lower shell 320, and the upper shell 310 and the lower shell 320 are connected up and down to form a water storage chamber.
[0070] An air pipe 321 is provided in the lower shell 320. The air pipe 321 and the lower shell 320 are integrally formed. There is a gap between the upper end of the air pipe 321 and the upper shell 310. The water storage upper limit of the water storage chamber is lower than the upper end of the air pipe 321. The lower end of the air pipe 321 is connected to the ventilation pipeline 500.
[0071] Since the ventilation pipe 500 is connected to the bottom of the water tank 300, the setting of the air pipe 321 is equivalent to extending the air inlet port of the ventilation pipe 500 upward, so that the ventilation pipe 500 is connected to the upper space in the water tank 300, preventing the water in the water tank 300 from flowing into the sewage pipe 200 through the ventilation pipe 500.
[0072] Connecting the ventilation pipe 500 to the bottom of the water tank 300 has another function. Since the water tank 300 is placed on top, the ventilation pipe 500, the flushing pipe 400, and the sewage pipe 200 are all located at the bottom of the water tank 300, making full use of the installation space at the bottom of the water tank 300, which helps to improve the compactness of the structure and reduce the overall height of the toilet.
[0073] A first pipe joint 370 and a second pipe joint 380 are provided at the bottom of the lower shell 320 . The first pipe joint 370 is vertically connected to the air pipe 321 . The first pipe joint 370 is used to connect to the ventilation pipeline 500 , and the second pipe joint 380 is used to connect to the flushing main pipeline 410 .
[0074] In some embodiments of the present application, a clearance groove 330 for routing the ventilation pipe 500 is provided on the lower shell 320, a pipe routing port 340 is provided on the upper shell 310, the pipe routing port 340 is connected to the clearance groove 330, and a mounting seat 350 is provided on the upper part of the upper shell 310.
[0075] The arrangement of the giving groove 330 and the pipe routing opening 340 in the front middle area of the water tank 300 enables the water tank 300 to integrate the pipe routing function, making the routing of the pipeline more regular, compact and reliable.
[0076] In some embodiments of the present application, the top of the installation cavity 120 is open, and a portion of the water tank 300 is exposed from the top of the installation cavity 120 .
[0077] The toilet bowl includes a cover body 710 and a cover body seat 720 , the cover body 710 is rotatably connected to the cover body seat 720 , and the cover body seat 720 is disposed at the top opening of the installation cavity 120 to cover the exposed part of the water tank 300 .
[0078] The toilet is a smart toilet, and the cover 710 is a smart toilet cover, which integrates functions such as flushing, drying, and automatic lid opening.
