Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, a toilet 10 includes a bowl body 100, a water diversion seat 200, a water channel, and a protrusion. The bowl body 100 has a bowl 110 and a rim opening 120. The water diversion seat 200 is connected to the edge port 120 and located at the rear side of the toilet bowl 110. The water channel is located in the water distribution seat 200, and the water channel has a flushing port located on the front side wall of the water distribution seat 200. The protrusion is located within the waterway.

In this embodiment, the material of the bedpan body 100 is ceramic.

In this embodiment, the water diversion seat 200 is made of ceramic. The water diversion seat 200 is integrally formed with the bedpan body 100.

In this embodiment, the top surface of the water diversion seat 200 is flush with the edge port 120.

Referring to fig. 2 and 3, the channel includes a main channel 310, and the flush port includes a main flush port 311 provided in the main channel 310.

Referring to fig. 5, the protrusion includes a main protrusion 410 located within the main channel 310, the main protrusion 410 being proximate to the main flush port 311.

In this embodiment, the toilet bowl 110 includes a container 510 and a drainage trough 520 located at the bottom of the container 510. The receiving groove 510 is communicated with the drainage groove 520. In a section parallel to the top surface of the bowl body 100, the projected area of the receiving groove 510 in the section is larger than the projected area of the drainage groove 520 in the section.

At the boundary between the receiving groove 510 and the drainage groove 520, the size of the opening of the toilet bowl 110 is sharply reduced.

Referring to fig. 6, in the present embodiment, the main protrusion 410 includes an inclined surface 411 and a lifting surface 412, the inclined surface 411 is inclined toward the front side of the toilet bowl 110, and the lifting surface 412 is inclined toward the inside of the main water passage 310.

In this embodiment, the main protrusion 410 may be used to adjust the direction of the water sprayed from the main flush port 311. The inclined surface 411 makes the water discharged from the main flushing port 311 have not only a vertical downward component velocity but also a forward component velocity, so that the water ejected from the main flushing port 311 is flushed to the front side of the junction between the containing tank 510 and the sewage draining tank 520 of the toilet bowl 110, and the water rebounds to fall into the toilet bowl 110 after impacting the location, as shown in an area F in fig. 3, which is beneficial to achieving the effect of water flow turning, thereby improving the sewage draining capability of the toilet bowl 10. The raised surface 412 allows the water passing through the main channel 310 to achieve a greater flow rate at the top of the raised surface 412, i.e., the narrowing of the channel cross-section, and to allow the water to flush out of the main flush port 311 at the greater flow rate to some extent.

In this embodiment, the inclined surface 411 makes the water sprayed from the main flushing port 311 impact the junction between the containing groove 510 and the dirt discharging groove 520, and bounce back at the junction and fall into the dirt discharging groove 520.

The shape of the main protrusion 410 may be an arc-shaped curved surface or a trapezoidal mesa shape in consideration of manufacturing cost and manufacturing difficulty. In this embodiment, the main protrusion 410 is curved. The inclined surface 411 is an arc-shaped side surface of the arc-shaped curved surface. In other embodiments, the main protrusion may also have a trapezoidal mesa shape.

In the present embodiment, the x direction represents the horizontal direction, and the y direction represents the vertical direction. The bottom surface of the main water channel 310 is parallel to the horizontal direction x, and an included angle theta between the inclined surface 411 and the bottom surface of the main water channel 310 is 30-50 degrees. If the angle θ between the inclined surface 411 and the bottom surface of the main water passage 310 is too small, the water ejected from the main flush port 311 directly falls into the drain groove 520 along the rear side of the toilet bowl 110, and it is difficult to form the effect of turning the water flow in the drain groove 520. If the included angle θ between the inclined surface 411 and the horizontal direction x is too large, the water sprayed from the main flushing port 311 tends to fall into the toilet bowl 110 along the vertical direction y, so that the forward partial velocity is too small, and therefore the water sprayed from the main flushing port 311 is difficult to impact the boundary between the accommodating tank 510 and the dirt discharging tank 520.

In this embodiment, the main protrusion 410 is integrally formed with the water diversion seat 200.

Referring to fig. 3, in this embodiment, the flume further includes a secondary flume 320.

Referring to fig. 7, in this embodiment, the protrusion further includes a secondary protrusion 322 located in the secondary water channel 320, and the flush port further includes a secondary flush port 321 provided in the secondary water channel 320, and the secondary protrusion 322 is located at an end of the secondary water channel 320 far from the secondary flush port 321.

The shape of the sub protrusion 322 may be provided with reference to the shape of the main protrusion 410 in consideration of manufacturing cost and manufacturing difficulty. Can be in the shape of an arc curved surface or a trapezoidal table. In this embodiment, the secondary protrusion 322 is curved. In other embodiments, the secondary protrusions may also have a trapezoidal mesa shape.

In this embodiment, as shown in fig. 1, the toilet 10 further includes a water guiding step 340 located below the auxiliary flushing port 321 and surrounding the sidewall of the toilet bowl 110.

In this embodiment, as shown in fig. 3, the toilet 10 further includes a water storage channel 330 located in the water diversion seat 200 and near the rear side of the water diversion seat 200, and the main water channel 310 and the auxiliary water channel 320 are both communicated with the water storage channel 330.

The water storage channel 330 is connected to the water inlet 20 (refer to fig. 1) on the water diversion seat 200, and is used for collecting water during the flushing process, and the water is used for cleaning the dirt in the toilet bowl 110.

Part of the water in the water storage channel 330 is discharged from the main flushing port 311 through the main water channel 310. Another part of the water in the water storage passage 330 is discharged from the auxiliary flushing port 321 through the auxiliary water passage 320.

In this embodiment, the number of the auxiliary flushing ports 321 is one, and the water ejected from the auxiliary flushing ports 321 flows along the surface of the water guide step 340 counterclockwise to surround the sidewall of the toilet bowl 110 in the entire circumference. In the process of the counterclockwise flow, in each local area of the water guiding step 340, part of water flows from the water guiding step 340 into the toilet bowl 110, so that a vortex-shaped water flow is formed in the toilet bowl 110, which is helpful for increasing the flushing force of the sewage in the sewage discharging groove 520, and thus the sewage discharging effect of the toilet bowl 10 can be improved.

In the present embodiment, as shown in fig. 3, a region D represents a junction between the side wall of the main channel 310 and the side wall of the water storage channel 330. The side wall of the main water channel 310 and the side wall of the water storage channel 330 are in smooth transition at the joint, and on the section parallel to the top surface of the toilet bowl body 100, the joint is a smooth curve, which is beneficial to discharging the air flowing into the water of the main water channel 310 from the water storage channel 330, and there is no corner where the air can be trapped, so as to ensure the stability of the water speed sprayed out from the main flushing port 311.

In this embodiment, as shown in fig. 3, a flow guiding portion 323 protruding into the water storage channel 330 is disposed at a joint of the side wall of the auxiliary water channel 320 and the side wall of the water storage channel 330, and a side of the flow guiding portion 323 close to the water storage channel 330 is arc-shaped.

The flow guide part 323 is integrally formed in the water diversion seat 200, and is used for guiding a part of water in the water storage channel 330 to the auxiliary water channel 320.

The existing bathroom industry has higher and higher requirements on the industrial design of products, the products tend to have the trend of thin wall, and the problem of size limitation is more prominent. The structure of the flow guiding part 323 can fully utilize the space of the water distribution seat 200 at the joint part of the auxiliary water channel 320 and the water storage channel 330, and effectively avoid the defect of size limitation. As shown in fig. 3, a surface of the flow guiding portion 323 on a side close to the water storage channel 330 may be designed to be an arc shape with a smaller curvature, so that water flow can smoothly transit into the auxiliary water channel 320, air flowing into the auxiliary water channel 320 from the water storage channel 330 is discharged, a corner where air is retained does not exist, and the water velocity and stability of the auxiliary flushing port 321 during spraying are slowed down.

In addition, the front end of the flow guide part 323 is matched with the inner wall surface of the water diversion seat 200, so that the size of the joint of the secondary water channel 320 and the water storage channel 330 is obviously narrowed, and the size of the secondary water channel 320 at the rear end of the joint is still the previous wider size. So that a smaller proportion of the water in the water storage passage 330 is distributed into the secondary waterway 320 and the flow rate of the water is reduced.

Fig. 4 is another top sectional view of the toilet shown in fig. 1.

In other embodiments, as shown in fig. 4, the surface of the flow guiding portion 323 on the side close to the water storage channel 330 may also be designed in the shape of an arc surface 324 with smaller curvature. It is more advantageous to discharge the air in the water flowing from the water storage passage 330 into the secondary waterway 320.

In this embodiment, as shown in fig. 1, the ratio of the water yield of the main flushing port 311 to the total water yield of the auxiliary flushing port 321 is 55% to 70%. If the ratio of the water yield of the main flushing port 311 to the total water yield of the main flushing port 311 and the auxiliary flushing port 321 is greater than 70%, the amount of water sprayed from the auxiliary flushing port 321 is too small, it is difficult to ensure the cleaning effect of the water sprayed from the auxiliary flushing port 321 on the surface of the water guiding step 340, and dirt is easily left on the surface of the water guiding step 340. If the ratio of the water yield of the main flushing port 311 to the total water yield of the main flushing port 311 and the auxiliary flushing port 321 is less than 55%, the amount of water sprayed from the main flushing port 311 is too small, and it is difficult to discharge the dirt by the strong water flow formed by the water sprayed from the main flushing port 311, which affects the dirt discharge capability of the toilet 10.

In this embodiment, as shown in fig. 7, the secondary protrusion 322 is located at the junction of the secondary water channel 320 and the water storage channel 330 (see fig. 3). The water from the water storage channel 330 can flow into the secondary water channel 320 only by crossing the secondary protrusion 322, so as to reduce the flow rate of the water sprayed from the secondary flushing port 321, and prevent the water from splashing after the water sprayed from the secondary flushing port 321 strongly impacts the surface of the water guiding step 340 due to the excessive water speed.

In addition, after passing through the auxiliary protrusion 322, the water flows out from the auxiliary flushing port 321 in a form with a wide cross section, which further helps to make the water flowing out from the auxiliary flushing port 321 distributed on the water guiding step 340 uniformly to a large extent, and can achieve a better flushing effect.

In this embodiment, the auxiliary protrusion 322 is integrally formed with the water diversion seat 200.

In this embodiment, since the position of the main protrusion 410 disposed in the main water passage 310 and the position of the auxiliary protrusion 322 disposed in the auxiliary water passage 320 are different, the adjustment of the water with different resistances can be conveniently realized.

In this embodiment, the distribution of the resistance of the waterway to water is adjusted in the form of a protrusion provided in the waterway to achieve a desired distribution of the flush water amount of the main flush port 311 and the sub flush port 321.

In this embodiment, the main protrusion 410 is located at an end of the main water channel 310, which is close to the main flushing port 311 and is far from the main flushing port 311, so that compared with the resistance effect of the auxiliary protrusion 322 on the water flow in the auxiliary water channel 320, the resistance effect of the main protrusion 410 on the water flow in the main water channel 310 is weaker, which helps to maintain higher water outlet speed and energy, and realize the control of the water outlet amount of the main water channel 310 and the auxiliary water channel 320.

In this embodiment, the toilet bowl body 100 has a waste outlet 530, and the waste outlet 530 is located near the rear side of the toilet bowl 110. Specifically, the dirt outlet 530 is located on a rear sidewall of the dirt discharge groove 520. The dirt in the toilet bowl 110 is discharged out of the toilet bowl 10 through the dirt outlet 530.

Referring to fig. 2, in this embodiment, the bowl body 100 has a left-right symmetrical structure, and the bowl body 100 has a symmetry plane O' O perpendicular to the top surface of the bowl body 100. The symmetry plane O' O divides the bowl body 100 into left and right portions.

In this embodiment, the auxiliary flushing port 321 and the main flushing port 311 are respectively located on two sides of the symmetry plane O' O.

Fig. 8 is a perspective view of a toilet 10 according to another embodiment of the present invention. FIG. 9 is a top view of the toilet 10 shown in FIG. 8; fig. 10 is a top sectional view of the toilet bowl 10 shown in fig. 8.

In other embodiments, as shown in fig. 8 to 10, the auxiliary flushing port 321 and the main flushing port 311 are located on the same side of the symmetry plane O' O.

Accordingly, the main water channel 310, the water storage channel 330, and the auxiliary water channel 320 are biased to one side (left or right side) of the water diversion seat 200, so that an accommodating space 400 for accommodating circuit devices can be formed at the other side of the water diversion seat 200, and the spatial layout is more reasonable.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
