DETAILED DESCRIPTION

The technical schemes of the present disclosure will be further described below in combination with the accompanying drawings and by embodiments. It can be understood that the embodiments described herein are intended only to explain but not to limit the present disclosure.

In an embodiment of the present application, as shown in FIGS. 1 to 6, a toilet is provided. The toilet includes a toilet body 10 and a turn-over sewage drainage assembly 20. The turn-over sewage drainage assembly 20 includes a sewage drainage box 201, a rotary sewage drainage pipe 202, and the like. The rotary sewage drainage pipe 202 is arranged in the sewage drainage box 201, and communicates with a bowl cavity 101 of the toilet body 10 via a sewage drainage port 204 provided in the sewage drainage box 201. Driven by a drive device 203, the rotary sewage drainage pipe 202 may realize turning-over sewage drainage. The drive device 203 includes a motor and a transmission assembly or the like. The transmission assembly includes, for example, a gear, and the like.

The toilet body 10 is further provided with a mounting cavity 102 arranged side by side with the bowl cavity 101. As shown in FIG. 2, the mounting cavity 102 is located behind the bowl cavity 101. The turn-over sewage drainage assembly 20 is mounted within the mounting cavity 102. As shown in FIG. 1, the toilet body 10 is further provided with a service port 103 communicating with the mounting cavity 102 to facilitate maintenance of the turn-over sewage drainage assembly 20, replacement of components of the turn-over sewage drainage assembly 20, and the like. The service port 103 may be provided in a rear wall of the toilet body 10.

As shown in FIG. 1, the toilet body is further provided with a sewage drainage portion 104 communicating with the bowl cavity 101. The sewage drainage portion 104 may be provided in a tubular shape as shown in FIGS. 2 and 3. The sewage drainage portion 104 is provided with a trapway 104a, and an inlet 104b and an outlet 104c that communicate with the trapway 104a. The bowl cavity 101 and the trapway 104a are communicated via the inlet 104b. The inlet 104b is also an outlet of the bowl cavity 101.

The trapway 104a of the sewage drainage portion 104 communicates with the rotary sewage drainage pipe 202 via the outlet 104c, and the rotary sewage drainage pipe 202 is rotatably adjustable relative to the trapway 104a, and may be switched between an initial state and a sewage drainage state. When the toilet is in a sewage drainage state, sewage flows from the bowl cavity 101 into the trapway 104a via the inlet 104b, and then into the rotary sewage drainage pipe 202 via the outlet 104c to be drained.

As shown in FIGS. 2 and 3, in a sewage drainage direction of the trapway 104a, as indicated by the dashed arrow line in FIG. 2, a bottom wall 104d of the trapway 104a is obliquely arranged downwards, so that sewage flows smoothly into the rotary sewage drainage pipe 202, thereby improving the sewage drainage efficiency.

As shown in FIG. 3, an inclination angle of the bottom wall 104d of the trapway 104a relative to a horizontal direction is marked α, which is set to be greater than 0 degrees and less than or equal to 34 degrees. On the one hand, the provision of the inclination angle α enables the sewage to obtain high fluidity, and on the other hand, it may avoid splashing of the sewage in the rotary sewage drainage pipe 202, so as to improve the cleanliness in the rotary sewage drainage pipe 202 and reduce daily cleaning costs. Further, since the sewage drainage is carried out by a mode of turning-over sewage drainage, in the initial state, the rotary sewage drainage pipe 202 is located at an initial position (for example, the initial position may be provided to be vertical to a horizontal plane), and when sewage needs to be drained, the rotary sewage drainage pipe 202 rotates downwards, the sewage in the bowl cavity 101 and the rotary sewage drainage pipe 202 flow downwards under action of gravity to be drained. After the sewage drainage is completed, the rotary sewage drainage pipe 202 may rotate in a reverse direction to be reset, and a water seal is formed in the bowl cavity 101. If the inclination angle of the bottom wall 104d of the trapway 104a is too large, the position of the sewage drainage port 204 would be too low. In order to ensure a height of the water seal in the bowl cavity 101, a size of the rotary sewage drainage pipe 202 in an up and down direction will be increased, and accordingly, a size of the sewage drainage box 201 will be increased, which therefore reduces the utilization rate of the space inside the toilet body 10 and also increases the size of the toilet outline. Since the inclination angle of the bottom wall 104d of the trapway 104a is adapted to the turn-over sewage drainage assembly 20, the toilet provided by the embodiment of the present application does not need to be provided with a bent waterway to ensure water seal like an ordinary straight-drop toilet, or a bent waterway to produce a siphoning effect like an ordinary siphon toilet.

In the embodiment of the present application, the inclination angle of the bottom wall 104d of the trapway 104a is designed so that the bottom wall 104d is formed in a smooth slope shape, which facilitates the sewage to smoothly slide downward and flow into the rotary sewage drainage pipe 202, and then to utilize the rotation of the rotary sewage drainage pipe 202 to be drained. The design of the inclination angle of the bottom wall 104d effectively reduces the flushing noise while improving the sewage drainage effect.

In some exemplary embodiments, as shown in FIG. 3, the trapway 104a may be provided downwardly as a whole, and a top wall 104e of the trapway 104a is provided in parallel with the bottom wall 104d and obliquely downward, which enables the sewage to have better fluidity and prevent sewage from splashing to a certain extent.

In some exemplary embodiments, as shown in FIG. 3, on a vertical midvertical surface (a surface perpendicular to a horizontal surface) of the trapway 104a, a height of the trapway 104a is marked H. A minimum value of H is designed to be greater than or equal to 5.5 cm to obtain a large sewage drainage diameter so that the toilet has higher sewage drainage efficiency.

In some exemplary embodiments, as shown in FIG. 3, a height of the trapway 104a is marked H. A minimum value of H is designed to be greater than or equal to 5.5 cm, and the minimum value of H is designed to be less than or equal to 8.5 cm, so as to obtain a large sewage drainage diameter and reduce the influence on the profile of the toilet body 10, so as to obtain a higher appearance aesthetics.

In some exemplary embodiments, a minimum flow area of the trapway 104a is set in a range of 28.0 cm2 to 68.0 cm2. By controlling the minimum flow area of the trapway 104a, a higher flushing efficiency may be obtained.

In some exemplary embodiments, as shown in FIG. 3, a horizontal distance between an outlet 104c of the trapway 104a and the outlet of the bowl cavity 101 is marked L, that is, a horizontal distance between the inlet 104b and the outlet 104c of the trapway 104a. L is set in a range of 3.2 cm to 9.7 cm, which may, on the one hand, enable the sewage to obtain better fluidity, and on the other hand, provide a layout space of a mounting structure for connection between the sewage drainage portion 104 and the rotary sewage drainage pipe 202, thereby optimizing the overall structural design of the toilet.

In some exemplary embodiments, as shown in FIG. 2, an area of the bowl cavity 101 opposite the inlet 104b of the trapway 104a is provided as a sloped surface that smoothly connects with the trapway 104a, as shown in the dashed frame in FIG. 2. The dashed frame is schematic only and does not represent the actual design structure of the sloped surface of the bowl cavity 101 that smoothly connects with the trapway 104a. The area of the bowl cavity 101 opposite the inlet 104b of the trapway 104a is provided as a sloped surface that smoothly connects with the trapway 104a, which, on the one hand, may improve the fluidity of the sewage and improve the sewage drainage efficiency, and on the other hand, the sloped surface that smoothly connects with the trapway 104a is also beneficial to the cleaning operation and reduces the cleaning difficulty.

In some exemplary embodiments, as shown in FIGS. 2 and 3, a protrusion 105 is provided on an inner wall of the trapway 104a of the sewage drainage portion 104. The protrusion 105 may be integrally formed with the sewage drainage portion 104, and the sewage drainage portion 104 may be integrally formed with the bowl cavity 101. The protrusion 105 is located at the inlet 104b of the trapway 104a and protrudes downwardly. With the protrusion 105, the water seal height of the toilet body 10 may be conveniently adjusted, and sewage may be prevented from sticking to a top wall 104e of the trapway 104a to a certain extent, thereby reducing the difficulty of cleaning the trapway 104a as a whole. A minimum height and a minimum flow area of the trapway 104a may be designed at the protrusion 105, that is, a vertical height and a flow area at the inlet 104b of the trapway 104a are smaller than vertical heights and flow areas at other positions of the trapway 104a. Such design may prevent a user from seeing other areas of the trapway 104a through the inlet 104b, thereby affecting the user experience, and may reduce the visibility of the trapway 104a. On the other hand, in the sewage drainage direction, the trapway 104a is designed in a shape of a flared mouth, which also facilitates the drainage of sewage, thereby obtaining higher sewage drainage efficiency.

In some exemplary embodiments, as shown in FIGS. 2 to 5, a connection portion 106 is provided on an outer wall of the sewage drainage portion 104. The connection portion 106 is provided to fixedly connect to the sewage drainage box 201. The connection portion 106 may be provided as an annular structure surrounding the outlet 104c or the like. Fixed connection between the connection portion 106 and the sewage drainage port 204 of the sewage drainage box 201 may be a bolt connection, as shown in FIG. 2, or a clamping connection, or the like, and the clamping connection may be a buckle-type connection, a clamping band connection, or the like. A child buckle and a mother buckle may be used in the buckle-type connection. The mother buckle 205 may be fixed on the sewage drainage box 201, and the child buckle 206 may be fixed on the connection portion 106. The mother buckle 205 and the child buckle 206 are tightened and fastened, as shown in FIG. 4. An upper clamping band 207 and a lower clamping band 208 may be used in the clamping band connection. The upper clamping band 207 is attached to a side where the connection portion 106 connects to the sewage drainage box 201, such as an upper side, and the lower clamping band 208 is attached to the other side where the connection portion 106 connects to the sewage drainage box 201, such as a lower side. The upper clamping band 207 and the lower clamping band 208 are fixed by screws or the like, so as to mount the sewage drainage box 201 to the toilet body 10, as shown in FIG. 5. A seal may further be provided between the connection portion 106 and the sewage drainage box 201 to improve the sealability of the connection area.

In some exemplary embodiments, as shown in FIGS. 1 and 6, the toilet further includes a brush ring assembly 30, a shifter assembly 40, and the like. The brush ring assembly 30 is mounted on the toilet body 10 and communicates with the bowl cavity 101 to deliver brush ring water into the bowl cavity 101. The shifter assembly 40 may be arranged in the mounting cavity 102, one end of the shifter assembly 40 communicates with the sewage drainage box 201, and the other end of the shifter assembly 40 communicates with a drain port on the ground to achieve smooth sewage drainage of the toilet.
