The present embodiment discloses a toilet, referring to fig. 1 to 6, which includes a main body 100, a sewage drain 200, a flushing pipe 400, a ventilation pipe 500, a water tank 300, a lifting assembly 900, etc.

The main body 100 has a ceramic structure, and a urinal cavity 110 and a mounting cavity 120 are formed therein. The installation chamber 120 is used to install the drain pipe 200, the flush line 400, the vent line 500, the tank 300, etc. The closestool has compact overall structure layout, small volume and small occupied space. Fig. 6 is a schematic longitudinal sectional view of the main body 100.

The chamber 110 has a flush inlet and a flush outlet 114. The flush water for sewage flows into the chamber 110 from the flush water inlet, washes the dirt in the chamber 110, and discharges the dirt in the chamber 110 from the flush water outlet 114 by the water flow.

The flushing line 400 is provided in the installation chamber 120, and the flushing line 400 communicates with the flushing inlet for flushing water into the toilet chamber 110. The flushing inlet may be provided at a plurality of positions so that the flushing pipe 400 flushes water to a plurality of positions of the chamber 110 at the same time, thereby improving the sewage discharge effect.

A drain conduit 200 is provided within the mounting chamber 120, the drain conduit 200 being in communication with the flush outlet 114 for draining contaminants from within the chamber 110.

A first water seal area 210 is formed at a communication position of the sewage drain 200 and the flush outlet 114, and a second water seal area 220 is formed in the sewage drain 200. The first and second water seal areas 210 and 220 are illustrated in fig. 5 by dashed boxes. The sewage drain 200 forms a double water seal structure through a bending structure of the sewage drain, so that odor overflow is effectively prevented.

The water tank 300 is provided in the installation cavity 120, and the water tank 300 communicates with the flush line 400 for supplying water into the flush line 400.

The ventilation pipeline 500 is communicated between the water tank 300 and the sewage drain pipeline 200, the communication position of the ventilation pipeline 500 and the water tank 300 is higher than the upper limit 360 of the water storage of the water tank 300, and the communication position of the ventilation pipeline 500 and the sewage drain pipeline 200 is positioned on the pipeline between the first water seal area 210 and the second water seal area 220.

When sewage is discharged, the water tank 300 supplies water into the flushing pipeline 400, the water in the water tank 300 flows into the urinal cavity 110 through the flushing pipeline 400 and the flushing inlet to flush the sewage in the urinal cavity 110, in the process, the water level in the water tank 300 continuously drops, negative pressure is formed in the upper space in the water tank 300, under the action of the negative pressure, air in the pipeline between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipeline 500, so that the negative pressure is also formed in the pipeline between the first water seal area 210 and the second water seal area 220, and a pulling force is formed in front of the first water seal area 210 (along the water flowing direction), so that the water in the urinal cavity 110 is sucked, and the water flowing speed is improved. Thus, the water and dirt in the toilet bowl 110 are discharged along the sewage drain pipe 200 to the outside, and one power is the flushing power of the water flowing into the toilet bowl 110 from the flushing pipe 400 and the flushing inlet, and the other power is the water absorbing power of the water in the toilet bowl 110 due to the fact 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 negative pressure is formed in the pipe between the first water seal area 210 and the second water seal area 220, so that the flushing and sewage draining speed is faster, and a better sewage draining effect is achieved with the minimum water quantity.

The toilet bowl is a double-power siphon type sewage discharging mode, and the arrangement of the ventilation pipeline 500 enables the siphon in the sewage discharging pipeline 200 to be a double-power structure of pulling the water and the sewage in the urinal cavity 110 forwards and backwards, so that the water consumption is greatly reduced under the condition of achieving the same sewage discharging effect.

When the water level in the water tank 300 reaches the upper limit 360 of the water storage, the water in the water tank 300 can be effectively prevented from flowing into the sewage drain 200 from the vent pipeline 500 because the communication position between the vent pipeline 500 and the water tank 300 is higher than the upper limit 360 of the water storage of the water tank 300.

The upper limit 360 of the water tank 300 is spaced from the top of the water tank 300 by a distance corresponding to a space for air filling reserved at the top of the water tank 300, and one end of the vent pipe 500 is connected to the space for air filling.

The lifting assembly 900 is provided at the rear of the main body for adjusting the distance between the main body 100 and the ground 20. The toilet back wall 30 is provided, and the lifting assembly 900 is provided in the gap between the main body 110 and the back side wall 30, see fig. 1 and 2.

The lifting assembly 900 is adjusted according to the height of the user, and the distance between the main body 100 and the ground 20 is adjusted, so that the main body 100 is placed at a proper height position, and the use experience of the user is improved.

In some embodiments of the present application, referring to fig. 5, the location of the communication of the vent line 500 with the drain 200 is at the top of the drain 200. When the dirt is discharged along the drain pipe 200, the dirt is effectively prevented from flowing backward into the water tank 300 along the vent pipe 500.

In some embodiments of the present application, referring to fig. 5, the drain outlet of the drain pipe 200 extends rearward of the main body 100, i.e., the toilet is wall-mounted.

A sewage communication pipe 240 is provided in the wall 30 at the rear of the toilet bowl for communicating the sewage pipe 200 with an outdoor sewage main pipe.

The lifting assembly 900 is arranged at a position which fully utilizes the gap between the wall-mounted toilet and the rear wall, and has compact layout.

In some embodiments of the present application, referring to fig. 5, the drain 200 includes a first drain section 231, a second drain section 232, a third drain section 233, and a fourth drain section 234 that are sequentially connected. The first drain pipe section 231 extends obliquely upward from the flush outlet 114, the second drain pipe section 232 extends downward from the top of the first drain pipe section 231, the third drain pipe section 233 extends obliquely upward from the bottom of the second drain pipe section 232 in a direction away from the first drain pipe section 231, and the fourth drain pipe section 234 extends horizontally from the top of the third drain pipe section 233 to the rear of the toilet.

The first water seal area 210 is formed at the position where the first sewage drain pipe section 231 is communicated with the flushing outlet 114, and the second water seal area 220 is formed at the position where the second sewage drain pipe section 232 is communicated with the third sewage drain pipe section 233.

One end of the vent pipe 500 is arranged at the position where the first section 231 of the sewage drain pipe is communicated with the second section 232 of the sewage drain pipe, so that the vent pipe 500 is positioned at the top of the sewage drain pipe 200, and sewage is prevented from flowing backwards into the vent pipe 500 during sewage drain.

In some embodiments of the present application, referring to fig. 7 or 10, the flush line 400 includes a main flush line 410, a first flush branch line 420, and a second flush branch line 430, where a water pump 450 is disposed on the main flush line 410, and the main flush line 410, the first flush branch line 420, and the second flush branch line 430 are connected through a diverter valve 440. The main flush line 410 communicates with the tank 300.

Referring to fig. 5 and 6, the bottom of the urinal cavity 110 is provided with a dirty chamber 113 and a first flush water inlet 111 communicating with the dirty chamber 113, a flush water outlet 114 communicating with the dirty chamber 113, the first flush water inlet 111 being disposed opposite to the flush water outlet 114.

A water guide groove 115 is provided at the top of the bowl 110 in the circumferential direction thereof, and a second flush inlet 112 communicating with the water guide groove 115 is provided at the top of the bowl 110.

The first flush leg 420 communicates with the first flush inlet 111 and the second flush leg 430 communicates with the second flush inlet 112.

During flushing, water in the water tank 300 flows into the first flushing branch pipeline 420 and the second flushing branch pipeline 430 through the flushing main pipeline 410 and the water dividing valve 440, water in the second flushing branch pipeline 430 flows out from the second flushing inlet 112, flows along the water guide groove 115 in the process of flowing along the inner peripheral wall of the urinal cavity 110 to the sewage inlet cavity 113, washes sewage in the urinal cavity 110, and pushes the sewage in the sewage inlet cavity 113 into the flushing outlet 114 from the first flushing inlet 111, flows into the sewage discharge pipeline 200 and discharges the sewage.

In some embodiments of the present application, the amount of water entering the first flush leg 420 from the flush main line 410 is less than the amount of water entering the second flush leg 430, allowing more water to flow down the top of the chamber 110, improving the blowdown flush effect of the chamber 110, while helping to reduce the amount of water used.

The flow of the sewage in the sewage inlet cavity 113 into the sewage drain pipeline 200 has two driving forces, one is the flushing power flowing out from the first flushing inlet 111, the sewage in the sewage inlet cavity 113 is flushed into the sewage drain pipeline 200, and the other is the water absorbing power for sucking the water and the sewage in the sewage inlet cavity 113 because the air in the pipeline between the first water seal area 210 and the second water seal area 220 flows into the water tank 300 through the ventilation pipeline 500, and negative pressure is formed in the pipeline between the first water seal area 210 and the second water seal area 220, so that the flushing and sewage draining speed is higher, and a better sewage draining effect is achieved with the least water quantity.

It is because the siphon energy in the sewage drain pipe 200 can achieve the double power effect of pushing forward and pulling backward on the water and dirt in the urinal cavity 110, so that the water quantity flowing into the first flushing branch pipe 420 is not required to be distributed through the water diversion valve 440, more water can flow into the second flushing branch pipe 430, more water flows downwards from the top of the urinal cavity 110, the sewage draining and flushing effect of the urinal cavity 110 is improved, and the effect of reducing the water consumption is achieved.

As for the arrangement position of the water tank 300 relative to the drain pipe 200, two embodiments are given in this embodiment, the first is that the water tank 300 is laterally arranged, that is, the water tank 300 is disposed beside the drain pipe 200, as shown in fig. 3 to 8; the second is that the water tank 300 is overhead, i.e., the water tank 300 is disposed above the drain pipe 200, as shown in fig. 9 to 14.
