Elaborate

The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The embodiments and features in the embodiments of the present disclosure may be arbitrarily combined with each other unless there is any conflict.

Regular toilets need to be used with a shifter. During installation, the outlet end of the shifter must first be connected and sealed with the floor sewage pipe, and then the inlet end of the shifter must be connected and sealed with the toilet sewage outlet. The assembly process is complicated and the cost is relatively high.

The sewage box, sewage system and toilet provided by the embodiments of the present disclosure can eliminate the need for a shifter, thus simplifying the installation process and reducing costs.

The following is explained with reference to the accompanying drawings.

As shown in Figure 1, one embodiment of the present disclosure provides a sewage discharge box 1 for use in a toilet. The toilet further includes a sewage pipe 2 at least partially disposed in the sewage discharge box 1, as shown in Figures 2, 4 and 5. Show.

Among them, as shown in FIG. 3 , the sewage discharge box 1 includes a box body 10 and a connecting pipe 3 . As shown in FIGS. 2 to 5 , the box body 10 is provided with a rotary connection hole 13 and a waste outlet 14 . The rotary connection hole 13 is configured to be rotatably connected to the sewage pipe 2 . The connecting pipe 3 is connected to the box body 10 and to the waste outlet 14, and is configured to be connected with the floor sewage pipe to discharge dirt into the floor sewage pipe.

In the sewage discharge box 1 provided by the embodiment of the present disclosure, the box body 10 is provided with a rotation connection hole 13 and a dirt outlet 14. The rotation connection hole 13 is configured to be rotationally connected with the sewage discharge pipe 2. The sewage inlet of the sewage pipe 2 is connected with the sewage outlet 511 of the pelvic cavity 51 of the toilet seat 5 . The sewage pipe 2 is at least partially located in the sewage box 1 and is rotationally connected to the rotation connection hole 13 so that it can rotate in the sewage box 1 . The sewage pipe 2 can be set to rotate from top to bottom, and then the gravitational potential energy and falling inertia of the dirt are used to discharge the dirt out of the sewage pipe 2, thereby realizing the flipping sewage discharge function.

When sewage is discharged, the waste in the toilet basin 51 enters the sewage pipe 2, and as the sewage pipe 2 rotates downward, it is discharged from the sewage pipe 2 under the action of gravity and inertia, and is discharged through the waste outlet 14 of the box body 10, as shown in Figure 6. As shown in Figure 7. Since the dirt outlet 14 of the box body 10 is connected to the connecting pipe 3, and the connecting pipe 3 is configured to dock with the floor sewage pipe, the dirt discharged from the dirt outlet 14 is directly discharged into the floor sewage pipe through the connecting pipe 3.

Therefore, when installing a toilet using this sewage box, the connecting pipe 3 can be directly connected and sealed with the floor sewage pipe without needing to be transferred through a shifter. This is equivalent to the sewage box integrating the shifter function, so The shifter can be omitted, and a docking and sealing process is correspondingly reduced, thereby simplifying the installation process of the toilet and reducing the number of parts, which is beneficial to reducing costs.

Among them, the sewage pipe 2 can be completely located inside the sewage box 1, then the sewage box 1 is fixedly connected to the toilet seat 5, the sewage pipe 2 is rotationally connected to the sewage box 1, and a seal can be provided between the connection part of the sewage pipe 2 and the sewage box 1 structure, a sealing structure can also be provided between the connection part of the sewage box 1 and the toilet seat 5.

Alternatively, the sewage pipe 2 can also be partially located in the sewage box 1 . For example, the sewage box 1 is fixedly connected to the toilet seat 5 . The sewage inlet pipe section of the sewage pipe 2 can extend out of the sewage box 1 through the rotating connection hole 13 and be inserted into the sewage outlet 511 of the toilet seat 5 to achieve communication with the sewage outlet 511 . Moreover, the sewage pipe 2 can rotate relative to the toilet seat 5 and the sewage box 1 .

In an exemplary embodiment, the connecting pipe 3 has a port for docking with the floor sewage pipe, and the port is mirror symmetrical with respect to the vertical plane (ie, the interface 15) where the central axis of the rotating connecting hole 13 is located, as shown in Figure 6 and shown in Figure 7.

Since the sewage outlet 511 of the toilet basin 51 is usually located in the middle position in the width direction of the toilet, and the rotating connection hole 13 is directly connected to the sewage outlet 511 of the pelvic cavity 51, the vertical plane where the central axis of the rotating connecting hole 13 is located is the pelvic cavity. 51 The sewage outlet 511 is along the middle vertical plane in the vertical direction. Since the inlet of the floor sewage pipe is usually located in the middle position in the width direction of the toilet, the vertical plane where the central axis of the rotating connection hole 13 is located is also the middle vertical plane of the entrance of the floor sewage pipe.

When the port of the connecting pipe 3 docking with the floor sewage pipe is also mirror-symmetrical with respect to the vertical plane, the port faces directly downward, and the connecting pipe 3 can directly connect downward to the floor sewage pipe, which is beneficial to reducing the friction between the connecting pipe 3 and the floor sewage pipe. Docking difficulty, thereby improving installation efficiency.

In an exemplary embodiment, as shown in Figures 4, 5 and 8, the connecting pipe 3 includes a transversely extending transition section 35 and a vertically extending sewage discharge section 36. One end of the transition section 35 is connected to the wastewater. The other end of the outlet 14 is connected to the upper end of the sewage section 36, and the lower end of the sewage section 36 is configured to be connected with the floor sewage pipe. Therefore, the lower end of the sewage section 36 is the port of the connecting pipe 3 for connecting to the floor sewage pipe.

Among them, at least the sewage discharge section 36 is mirror symmetrical with respect to the vertical plane where the central axis of the rotation connection hole 13 is located.

In this way, the sewage discharge section 36 is located directly above the entrance of the floor sewage pipe, which facilitates the full use of gravity to achieve full fall of the dirt, thereby improving the sewage discharge performance of the toilet and reducing the retained dirt in the sewage discharge section 36 . Moreover, this also helps to further reduce the difficulty of connecting the connecting pipe 3 with the floor sewage pipe.

The transition section 35 may or may not be mirror symmetrical with respect to the vertical plane. When the transition section 35 is mirror symmetrical or approximately mirror symmetrical with respect to the vertical plane where the central axis of the rotation connection hole 13 is located, the dirt outlet 14 of the box body 10 is also located at the middle position in the left and right direction of the toilet seat 5 .

Compared with locating the dirt outlet 14 of the box body 10 on one side of the box body 10 in the left and right direction, this solution is conducive to reducing the distance between the dirt outlet 14 and the floor sewage pipe, and thereby is conducive to simplifying the connection pipe 3 The structure also makes it easier for the connecting pipe 3 to connect with the floor sewage pipe.

In one example, as shown in FIG. 8 , the sewage discharge section 36 extends in the vertical direction, so the influence of gravity on the falling of dirt is more significant, which is beneficial to further improving the sewage discharge performance of the toilet and further reducing the retained dirt in the sewage discharge section 36 .

In one example, as shown in Figure 8, the transition section 35 extends in the horizontal direction.

In one example, referring to FIG. 8 , the waste outlet 14 of the box body 10 opens forward, and the waste discharge section 36 extends vertically, so a transition section 35 needs to be provided between the waste outlet 14 and the waste discharge section 36 for transition. In this way, the connecting pipe 3 plays a role in causing the dirt to change direction and flow downward. Moreover, the transition section 35 can also play a role in slowing down the flow speed of dirt, reducing the impact of dirt on the wall of the connecting pipe 3 and causing the retention of dirt under high impact force. Usually, the retention at this place is difficult to pass through flushing. removed.

Referring to FIGS. 2 and 3 , in an exemplary embodiment, the box body 10 includes: a box body 11 and a box cover 16 . The box body 11 is provided with a rotation connection hole 13 and a dirt outlet 14, and is an integral structure with at least a part of the connection pipe 3. The box cover 16 covers the box body 11 and is fixedly connected to the box body 11 .

Splitting the box body 10 into the box body 11 and the box cover 16 not only simplifies the respective structures of the box body 11 and the box cover 16 , facilitates the processing of the box body 11 and the box cover 16 , and also facilitates the assembly of the sewage pipe 2 .

At least part of the box body 11 and the connecting pipe 3 is an integrated structure, which can be integrally formed by injection molding or other methods. The sealed connection between the box body 11 and the connecting pipe 3 can be achieved, and the connection strength and sealing reliability are high, and no need for Assembling the box body 11 and the connecting pipe 3 is helpful to further simplify the installation process of the toilet.

A sealing ring can be provided between the box cover 16 and the box body 11 to ensure the reliability of the connection between the box cover 16 and the box body 11 .

In one example, the box body 11 is provided on the front side of the box cover 16, and the box cover 16 is provided with a connection hole 161. As shown in Figure 2, the sewage pipe 2 is provided with a connection portion 23, and the driving device 4 is connected to the box through the connection hole 161. 23 are connected to each other to drive the sewage pipe 2 to rotate.

Both the box body 11 and the box cover 16 have irregular shapes in the left and right directions.

Taking the vertical plane where the central axis of the rotating connection hole 13 is located as the interface 15, the sewage box 1 is cut open along the vertical direction perpendicular to the interface 15. The outline of the inner wall of the sewage box 1 is asymmetrically arranged. irregular shape. The sewage discharge box 1 is cut open along the interface 15, and the outline of the inner wall of the sewage discharge box 1 is generally rectangular or rounded rectangular. The sewage discharge box 1 is cut along the horizontal direction perpendicular to the interface 15, and the outline of the inner wall of the sewage discharge box 1 is also generally rectangular or rounded rectangular.

Therefore, the irregular shape of the sewage discharge box 1 can be seen relatively clearly and intuitively from the front and rear directions in the figure.

Of course, the outer wall of the sewage discharge box 1 may also include some other structures, such as connecting lugs, connecting holes, and other structures, for installing and fixing the sewage discharge box 1 and the installation and fixation of the sewage discharge box 1 and the driving device 4 .

In an exemplary embodiment, as shown in Figure 6, the vertical plane where the central axis of the rotation connection hole 13 is located is the interface 15, and the inner wall of the box 10 is divided into a sewage discharge area 111 and a non-sewage discharge area. 112. During the rotation and discharge process, the sewage pipe 2 rotates from the side of the non-sewage area 112 to the side where the sewage area 111 is located.

Among them, the non-sewage discharge area 112 and the sewage discharge area 111 are arranged asymmetrically with respect to the interface 15 , and the space enclosed by the sewage discharge area 111 is larger than the space enclosed by the non-sewage discharge area 112 .

In Figure 6, the part of the inner wall of the box 10 located within the thin dotted line box on the left is the non-sewage discharge area 112; the part of the inner wall of the box 10 located within the thick dotted line box on the right is the waste discharge area 111.

Since the sewage pipe 2 only needs to rotate to one side during the rotation and discharge process, that is, to the side where the sewage area 111 is located, so as long as there is enough space on the side where the sewage area 111 is located, the rotation demand of the sewage pipe 2 can be satisfied. Yes, the size of the non-sewage area 112 has no impact on the rotation requirement of the sewage pipe 2 .

Based on this, in the sewage discharge box 1 provided by the embodiment of the present disclosure, the box body 10 adopts an asymmetrically arranged irregular shape, and the sewage discharge area 111 and the non-sewage discharge area 112 are designed to be asymmetrically arranged. Moreover, the space enclosed by the sewage discharge area 111 is relatively large to meet the rotation requirements of the sewage discharge pipe 2, while the space enclosed by the non-sewage discharge area 112 is relatively small. Compared with the box body 10 using regular symmetry, this solution is equivalent to reducing the size of the non-sewage discharge area 112, so that the space surrounded by the non-sewage discharge area 112 is reduced, thus reducing the volume of the sewage discharge box 1 and reducing the cost. The demand for assembly space of the sewage discharge box 1 is conducive to improving the adaptability and flexibility of the sewage discharge box 1 .

Moreover, this solution mainly allocates the internal space of the sewage discharge box 1 to the sewage discharge area 111, so that the internal space of the sewage discharge box 1 is mainly used for sewage discharge, thus improving the space utilization rate in the sewage discharge box 1, which is conducive to increasing the available space for sewage discharge and reducing the Chances of blockage occurring.

Among them, the sewage pipe 2 rotates from the non-sewage area 112 side to the side where the sewage area 111 is located during the rotating sewage discharge process. Only the rotation direction (clockwise rotation or counterclockwise rotation) of the sewage discharge pipe 2 during the rotation sewage discharge process is adjusted. There is no limit to the initial position of the sewage discharge pipe 2. During the rotational sewage discharge process, the sewage pipe 2 must rotate from top to bottom in order to use gravity to discharge the dirt in the pipe. Therefore, the rotation direction of the sewage pipe 2 can be confirmed based on the relative positions of the sewage discharge area 111 and the non-sewage discharge area 112 . The initial sewage discharge position of the sewage pipe 2 can be in a vertical state, as shown in Figure 6. At this time, part of the sewage outlet 21 of the sewage pipe 2 can be located in the space on the side of the non-sewage area 112, and part of it can be located on the side of the sewage area 111. within the space; the initial position of the sewage discharge pipe 2 can also be in a slightly tilted state. At this time, the sewage outlet 21 of the sewage pipe 2 can be completely located in the space on one side of the sewage area 111.

In an exemplary embodiment, the space surrounded by the sewage area 111 is configured such that the maximum rotation angle provided for the sewage pipe 2 is in the range of 100° to 135°.

In other words, due to the limitation of the shape of the sewage area 111, the sewage pipe 2 can only rotate 100° to 135° in the sewage box 1. If it continues to rotate, it will interfere with the box body 10.

Compared with the solution where the sewage pipe 2 is rotated 180° (from vertical upward to vertical downward), in this solution, the sewage pipe 2 only needs to be rotated 100° to 135°, which reduces the rotation time and helps improve the sewage efficiency. . Moreover, this solution also reduces the volume of the box body 10 of the sewage discharge box 1, which is beneficial to improving the flexibility and adaptability of the sewage discharge box 1.

In one example, the width of the drainage area 111 in the horizontal direction perpendicular to the interface 15 is greater than the width of the non-sewage area 112 in the horizontal direction perpendicular to the interface 15 .

The width of the sewage area 111 in the horizontal direction perpendicular to the interface 15 needs to be greater than the distance between the sewage outlet 21 of the sewage pipe 2 and the rotation axis of the sewage pipe 2 (that is, the central axis of the rotation connection hole 13), so as to ensure the sewage discharge. When the pipe 2 is rotated to the horizontal direction, it will not interfere with the inner wall surface of the sewage discharge box 1 . The width of the non-sewage area 112 in the horizontal direction perpendicular to the interface 15 is not limited by this, and therefore can be designed smaller to reduce the volume of the sewage box 1 .

In this way, the box body 10 of the sewage discharge box 1 has an eccentric design as a whole, that is, the central axis of the rotation connection hole 13 is biased toward the non-sewage discharge area 112 in the horizontal width direction of the box body 10 (i.e., the left and right direction in the figure). One side, instead of being located at the center of the horizontal width direction of the box body 10, can not only meet the demand for one-sided rotation of the sewage pipe 2, but also reduce the volume of the box body 10, thereby improving the flexibility of the sewage drainage system 100. sex and adaptability.

In an exemplary embodiment, at least the sewage area 111 is provided with a sewage guide surface 6 for guiding the sewage to flow toward the sewage outlet 14, as shown in Figures 4, 5, 7, 8 and 10.

The sewage discharge guide surface 6 can guide the sewage, which is beneficial to the smooth and rapid flow of the sewage to the connecting pipe 3, thereby improving the sewage discharge performance of the toilet.

In one example, as shown in Figures 6 and 7, the inner edge of the sewage area 111 is set in a roughly semicircular shape (a vertical area between two arc sections), and its radius is larger than the rotation radius of the sewage pipe 2. When When the sewage pipe 2 rotates to the point where the dirt begins to slide down due to its own gravity potential, the inner wall of the sewage box 1 toward which the sewage outlet 21 is facing begins to gradually slope inward and downward from the vertical state to the arc state until the waste outlet 14, and this section is towards the The downwardly inclined arc-shaped inner surface is configured as at least a part of the sewage guide surface 6 . The arc-shaped surface is conducive to improving the efficiency of sewage discharge.

In an exemplary embodiment, as shown in FIGS. 4 and 5 , part of the sewage guide surface 6 is provided on the box body 11 and part is provided on the box cover 16 . The bottom of the box body 11 and the bottom of the box cover 16 are also arc-shaped and inclined toward the waste outlet 14 . The box body 11 and the box cover 16 are smoothly connected. This part also forms a part of the sewage guide surface 6 . The inner surface of the transition section 35 of the connecting pipe 3 can also be formed as part of the drainage surface 6 . This avoids the retention of waste due to the appearance of corners during the waste discharge process.

In an exemplary embodiment, as shown in Figures 8, 9 and 10, the connecting pipe 3 is located directly in front of the waste outlet 14; the wastewater guide surface 6 is along the direction from back to front and from the wastewater outlet. The area 111 points to the non-sewage area 112 and extends obliquely from up to down.

Since the sewage pipe 2 discharges dirt in the radial direction in the sewage area 111, and the connecting pipe 3 is located directly in front of the dirt outlet, the position where the sewage pipe 2 discharges dirt is located on the oblique rear upper side of the connecting pipe 3, so the dirt It needs to flow from back to front to get close to the connecting pipe 3 in the front and rear direction, and it needs to flow from the sewage discharge area 111 to the non-sewage discharge area 112 to get close to the connecting pipe 3 in the left and right directions, and it needs to flow from top to bottom to get close to the connecting pipe 3 in the up and down direction. Enter the sewage pipe 2.

With such an arrangement, the dirt can always flow toward the connecting pipe 3 in a downward trend under the influence of gravity potential energy during the discharge process, thereby avoiding the retention of dirt.

In an exemplary embodiment, the sewage guide surface 6 is provided as a smooth surface, which is conducive to the smooth and smooth sliding of dirt.

Since different families have different toilet pit distances, when the toilet pit distance changes, shifters of different specifications are usually used to match. In order to improve the adaptability of the toilet, the embodiment of the present disclosure cleverly designs the connecting pipe 3 of the sewage box 1 so that the connecting pipe 3 of the sewage box 1 can adapt to different toilet pit distances, thereby improving the versatility of the toilet.

Here are several options for adapting to different toilet pit distances.

In an exemplary embodiment, as shown in Figures 3, 4, 5 and 10, the connecting pipe 3 includes: a first butt pipe 32 and a second butt pipe (not shown in the figure).

One end of the first docking pipe 32 is connected to the waste outlet 14 , and the other end of the first docking pipe 32 is configured to dock with the first floor sewage pipe. The first docking pipe 32 is also provided with a normally closed backup port 321 .

One end of the second docking pipe is configured to dock with the opened backup port 321, and the other end of the second docking pipe is configured to dock with a second floor sewage pipe whose toilet pit distance is greater than the first floor sewage pipe.

Among them, the second butt pipe and the first butt pipe 32 are connected to one end of the first floor sewage pipe and are used alternatively.

Referring to FIGS. 4 and 5 , one end of the first butt pipe 32 is connected to the waste outlet 14 , and the first butt pipe 32 can be downwardly connected to the first floor sewage pipe with a relatively small distance from the toilet pit. The backup port 321 can be kept in a normally closed state by using seals such as screw caps and buckle caps, or it can be directly integrated into a closed state to avoid leakage of dirt at the backup port.

When it is necessary to connect the second floor sewage pipe whose distance from the toilet pit is larger than that of the first floor sewage pipe, open the backup port 321, connect one end of the second docking pipe to the backup port 321, and connect the other end to the second floor sewage pipe. Furthermore, it is necessary to seal one end of the first docking pipe 32 which is connected to the first floor sewage pipe, and can be sealed by using a sealing cap such as a screw cap or a buckle cap. In this way, one connecting pipe 3 can match various toilet pit distances. During actual installation, you can choose whether to connect the second butt pipe according to the specific toilet pit distance.

Among them, the first butt pipe 32 includes the above-mentioned transition section 35 and sewage discharge section 36 . The opening of the backup port 321 can be horizontally facing forward, and the second butt pipe can be L-shaped.

In an exemplary embodiment, the first butt tube 32 and the box body 11 are of an integrated structure, which can improve the connection strength and sealing reliability of the first butt tube 32 and the box body 10, and can also eliminate the need for the first pair. Take over the installation process of 32.

In another exemplary embodiment (not shown in the figure), the connecting pipe 3 includes: a tee pipe joint, a first butt pipe and a second butt pipe.

The three-way pipe joint includes a first port, a second port and a third port, and the first port is connected with the waste outlet 14 . One end of the first butt pipe is configured to be connected to the second port, and the other end of the first butt pipe is configured to be connected to the first floor sewage pipe. One end of the second butt pipe is configured to be connected to the third port, and the other end of the second butt pipe is configured to connect to the second floor sewage pipe whose distance from the toilet pit is greater than that of the first floor sewage pipe; wherein, the first butt pipe 32 and The second pairing takes over and is used.

The inner surface of the first port connected to the waste outlet 14 is configured to have a waste discharge guide surface 6, which is smoothly connected to the waste outlet 14 so that waste will not be retained. One end of the first docking pipe 32 is docked with the second port, and the other end can be docked with the first floor sewage pipe. When the first docking pipe 32 is selected to be docked with the first floor sewage pipe, the third port can be kept closed by using seals such as screw caps and buckle caps to prevent the third port from opening and causing dirt to leak out. Here, choose the downward port as the second port.

When it is necessary to connect the second floor sewage pipe whose distance from the toilet pit is larger than that of the first floor sewage pipe, open the third port, connect one end of the second docking pipe to the third port, and the other end to the second floor sewage pipe. At this time, The second port can be kept closed using seals such as screw caps and buckle caps to prevent the third port from opening and causing dirt to leak out.

In this way, the sewage discharge box 1 can be adapted to different toilet pit distances without the need for a shifter, which is beneficial to reducing costs.

In yet another exemplary embodiment (not shown in the figure), the connecting pipe 3 is provided with a telescopic structure, and the telescopic structure is configured to change the horizontal length of the connecting pipe 3 so that the connecting pipe 3 can be connected to different toilet pit distances. floor sewage pipe.

This solution directly utilizes the telescopic properties of the telescopic structure to change the horizontal length of the connecting pipe, thereby enabling the sewage box 1 to adapt to floor sewage pipes with different pit distances.

Among them, the telescopic structure can be configured as a telescopic sleeve (a structure similar to an umbrella handle), and the inner tube can be connected to the box body 10, and the outer tube can be telescopic (of course, the outer tube can also be connected to the box body 10, and the inner tube can be connected to the box body 10). telescopic). In this way, when the dirt flows from the inner pipe to the outer pipe, it will not be retained due to the height difference at the intersection of the inner and outer pipes. In the embodiment of the present disclosure, the outer diameter of the port at the end of the inner tube away from the box body 10 can be gradually expanded to be the same as the inner diameter of the outer tube. The thickness of the edge of the outer diameter here should be as small as possible to further reduce the problem of dirt retention. risks. The connecting pipe 3 can also be provided with telescopic guide rails.

Alternatively, the telescopic structure may also include a corrugated tube. When docked with the first floor sewage pipe, the corrugated tube may be in a contracted state and be extruded until the inner wall has no wrinkles. When docked with the second floor sewage pipe, the bellows is in an unfolded state and is stretched to a state where the inner wall has no wrinkles. In this way, the expansion and contraction of the connecting pipe is realized and the smooth flow of dirt is ensured.

As shown in Figures 2 to 5, one embodiment of the present disclosure provides a sewage system 100, including: a sewage box 1, a sewage pipe 2 and a driving device 4 as in any of the above embodiments. The sewage pipe 2 is rotatably connected to the sewage box 1. The driving device 4 is connected to the sewage pipe 2 and is configured to drive the sewage pipe 2 to rotate relative to the sewage box 1 .

The sewage discharge system 100 provided by the embodiment of the present disclosure includes the sewage discharge box 1 of any of the above embodiments, and therefore has all the beneficial effects of any of the above embodiments, which will not be described again here.

The sewage discharge principle of the sewage discharge system 100 is as follows (shown in Figures 6 to 7):
