Description

Technical Field

[0001] The present invention relates to toilet technology, in particular to a toilet sewage discharge device and a toilet. Background Art

[0002] In order to achieve the design without embedded water tank, the existing toilet generally adopts the water tank design inside the ceramic, and uses water pump to pump water for flushing or adopts the water tankless design controlled by double valves. Whether it is with a water tank or without a water tank, it generally requires a double water path design of brush ring and jet sewage discharge. The ceramic adopts the "S" bend pipe that can generate siphon, and some use rubber bellows to discharge sewage and flush through axial flipping. The "S" bend pipe jet siphon has problems such as high noise or insufficient jet force and poor flushing performance. Although the bellows sewage discharge has low noise, the corrugated groove is easy to hide dirt and dirt, making the sewage discharge not smooth, which affects the flushing performance.

[0045] like Figure 1-Figure 15 As shown, the present application provides a toilet 100, including a toilet body 1 and a toilet sewage device 2 equipped with the toilet body 1. The toilet 100 can be a floor-standing toilet or a wall-mounted toilet. This embodiment is described in detail with a wall-mounted toilet.

[0046] like Figure 1-Figure 3 As shown, the toilet body 1 includes a basin body 11 and a mounting cavity 12, and the mounting cavity 12 is located behind the basin body 11 and can be arranged side by side with the mounting cavity 12 (see Figure 2 The basin body 11 includes a receiving cavity 110 that converges from the top of the toilet body 1 toward the bottom rear, and a sewage cavity 111 that is connected to the receiving cavity 110 and extends in a horizontal direction. The sewage cavity 111 is provided with a sewage outlet 1110 that is connected to the installation cavity 12. The toilet body 1 implemented in this application can be a ceramic part, and of course, it can also be a plastic part, a stainless steel part or other materials.

[0047] The toilet body 1 also includes a brush ring interface (not numbered, the brush ring interface in the attached figure is connected to a brush ring ejector 4), and a flushing system connected to the brush ring interface (not shown, refer to the prior art), the flushing system may include a control valve, a connecting water pipe, etc., and the flushing system may be installed in the installation cavity 12 to save space. The brush ring interface in this embodiment is located above the toilet body 1 and communicates with the basin body 11, and is used to perform brush ring flushing and water replenishment on the basin body 11. The installation cavity 12 is provided with a pipe interface (not numbered) communicating with the outside, and the toilet 100 also includes a sewage pipe 13 installed on the pipe interface.

[0048] like Figure 4a-4c , Figure 5-Figure 8 , Figure 9a-9c As shown, the toilet sewage device 2 includes a sewage box 20, a sewage straight pipe 21 accommodated in the sewage box 20, and a driving device 22 installed in the sewage box 20 and driving the sewage straight pipe 21 to rotate.

[0049] The sewage box 20 has a receiving chamber 200 (see Figure 7 ), and includes a waste input end 20a and a waste output end 20b respectively connected to the receiving chamber 200. The waste input end 20a is used for water supply or waste input, and the waste output end 20b is used for waste output. The waste output end 20b is tubular and extends to the rear of the toilet 100.

[0050] like Figure 5 As shown, the sewage box 20 includes a box body 20c and a rear cover 20d which is detachably assembled with the box body 20c and encloses a receiving chamber 200. The box body 20c is provided with a waste input end 20a, and the rear cover 20d is provided with a waste output end 20b. The sewage box 20 is assembled by the box body 20c and the rear cover 20d, so that it is convenient to install the sewage straight pipe 21 and other components. A sealing strip 20e is provided at the connection between the box body 20c and the rear cover 20d (see FIG. 2 ). Figure 7 ) is used to prevent dirt from leaking out of the sewage box 20.

[0051] like Figure 7 , Figure 8 As shown, the sewage straight pipe 21 is received in the receiving chamber 200, including an input port 211 and an output port 212 arranged at two opposite ends of the sewage straight pipe 21 in the axial direction. The end surface of the input port 211 is an inclined surface inclined relative to the axial direction of the sewage straight pipe 21. The input port 211 is rotatably mounted on the sewage input end 20a of the sewage box 20. The sewage input end 20a includes an outer port 201 and an inner port 202. The outer port 201 of the sewage box 20 is matched with the sewage outlet 1110 of the toilet body 1 (see Fig.10 , Fig.11 ), the inner port 202 and the input port 211 of the sewage straight pipe 21 can be rotatably assembled.

[0052] The sewage straight pipe 21 includes a first working state in which it is tilted above the horizontal plane to achieve a water seal (see Figure 9a , Fig.9c , Fig.10 ) and a second working state extending toward the rear of the toilet to achieve sewage discharge at the rear of the toilet ( Figure 9b , Fig.11 ).

[0053] like Fig.11 As shown, in this embodiment, when the sewage straight pipe 21 is in the second working state, the sewage straight pipe 21 extends horizontally toward the rear of the toilet 100 or slightly below the horizontal direction to achieve sewage discharge at the rear of the toilet 100.

[0054] Such as 4a, 4b, Figure 5 , Figure 7 As shown, the driving device 22 is installed on the sewage box 20 and connected to the sewage straight pipe 21. The driving device 22 is configured to drive the sewage straight pipe 21 to flip to switch between the first working state and the second working state. The driving device 22 can realize the automatic rotation of the sewage straight pipe 21. When sewage needs to be discharged (for example, a sewage discharge signal is received), the driving device 22 can drive the sewage straight pipe 21 to rotate to a position extending toward the rear of the toilet (that is, the sewage straight pipe 21 is in the second working state) to realize the sewage discharge process. When sewage discharge is completed, the driving device 22 can drive the sewage straight pipe 21 to rotate to a position tilted upward in the horizontal direction (that is, the sewage straight pipe 21 is in the first working state) so that the toilet body 1 forms a water seal.

[0055] The sewage box assembly 2 of the embodiment of the present application designs the sewage pipe 21 as a straight pipe, which is not easy to hide dirt and grime. At the same time, the flipping surface of the sewage straight pipe 21 (the end face of the input port 211) is designed to be an inclined surface inclined to the axial direction of the sewage straight pipe 21 for flipping and resetting. The sewage straight pipe 21 can be tilted upward in the horizontal direction to form a water seal during the flipping process, and then extended toward the rear of the toilet to discharge sewage, thereby realizing the normal water seal and horizontal sewage discharge function of the toilet.

[0056] The inclined surface matching design between the straight sewage pipe 21 and the sewage box 20 in the embodiment of the present application realizes the water seal requirement and the sewage discharge function after flipping, ensures the center height of the sewage output end, can adapt to the height of the sewage pipe currently hidden in the wall, and can directly replace the existing toilet without demolishing the wall and reinstalling it, which greatly reduces the user's installation cost.

[0057] And ensure that the sewage outlet height is consistent with that of the existing conventional water tank toilet, so as to achieve Figure 8 As shown, the end surface of the input port 211 of the sewage straight pipe 21 forms a first angle a1 with the axial direction of the sewage straight pipe 21 , and the range of the first angle a1 is: 45°≤a1≤60°.

[0058] In the embodiment of the present application, the first angle a1 is set between 45° and 60°, which can prevent the first angle a1 from being too large, causing the sewage straight pipe 21 to tilt downward, and the height of the input port 211 of the sewage straight pipe 21 needs to be reduced and cannot meet the problem of being compatible with the existing toilet sewage outlet. It can also prevent the first angle a1 from being too small, causing the sewage straight pipe 21 to tilt up after turning over to the second working state, affecting the sewage discharge performance.

[0059] Therefore, the design of the first angle a1 of the input port 211 of the sewage straight pipe 21 in the embodiment of the present application can not only make the sewage straight pipe 21 tilt upward to form a water seal of a certain height in the first working state, but also can extend to the rear of the toilet in the second working state to realize the function of sewage discharge at the rear of the toilet.

[0060] like Figure 7 As shown, the end face of the outer port 201 of the waste input end 20a of the waste discharge box 20 is perpendicular to the horizontal waste discharge direction, and the end face of the inner port 202 forms a second angle a2 with the opposite direction of the waste discharge direction. The range of the second angle a2 is: 45°≤a2≤60°, so that the inner port 202 and the input port 211 can be assembled without interfering with the rotation of the waste discharge straight pipe 21 to achieve two working states.

[0061] like Figure 5 , Figure 7 As shown, the sewage straight pipe 21 also includes a sealing oil seal ring 23 for sealing the connection between the input port 211 and the inner port 202, and a sealing gasket 24 for sealing the water inlet connection between the outer port 201 and the sewage outlet 1110. The sealing oil seal ring 23 and the sealing gasket 24 are used to prevent dirt leakage.

[0062] like Figure 8 As shown, the end face of the output port 212 of the sewage straight pipe 21 is an inclined plane inclined relative to the axial direction of the sewage straight pipe 21, and the inclination direction of the end face of the output port 212 is opposite to the inclination direction of the end face of the input port 211. The end face of the output port 212 forms a third angle a3 with the axial direction of the sewage straight pipe 21, and the third angle a3 is greater than the first angle a1. The angle range of the third angle a3 is 75°≤a3≤90°, so that when the drainage straight pipe 21 is in a water-sealed state, the output port 212 is kept flush with the horizontal plane as much as possible, and when the sewage is discharged to the rear of the toilet, the output port 212 is as far as possible toward the rear of the toilet, and does not affect the flipping movement of the sewage straight pipe 21.

[0063] like Figure 5-Figure 7As shown, the body of the sewage straight pipe 21 is provided with a connecting shaft 213, and the driving device 22 is installed on the outer wall of the sewage box 20; the driving device 22 includes a motor 220, a transmission assembly 221 and a power line 222, and the transmission assembly 221 extends into the sewage box 20 and is connected to the connecting shaft 213. The body of the sewage straight pipe 21 is provided with a connecting shaft 213, and the axis of the connecting shaft 213 is perpendicular to the end face of the input port 211, so as to ensure that when the structure of the toilet sewage device 2 is as compact as possible, the driving device 22 can still be connected to the connecting shaft 213, drive the sewage straight pipe 21 to turn over normally, and realize the switching between the two states of tilting the water seal and backward sewage discharge.

[0064] like Figure 9a-9c As shown, in the initial state (ref. Figure 9a ), the sewage straight pipe 21 is located in the initial position, that is, the sewage straight pipe 21 is in the first working state, and the sewage straight pipe 21 is tilted upward in the horizontal direction to maintain the water seal state of the toilet body 1 (refer to Fig.10 When sewage needs to be discharged, the driving device 22 drives the sewage discharge straight pipe 21 to rotate to the second working state. At this time, the sewage discharge straight pipe 2 extends horizontally toward the rear of the toilet or tilts slightly downward toward the rear of the toilet (see Figure 9b ), the dirt in the basin body 11 flows downward under the action of gravity and is discharged backward from the sewage straight pipe 21 (refer to Fig.11 After the sewage is discharged, the driving device 22 drives the sewage discharge straight pipe 21 to rotate to the first working state again for reset, and a water seal is formed in the basin body 11 again (refer to Fig.9c ).

[0065] The toilet 100 of the embodiment of the present application controls the flipping and resetting of the sewage straight pipe 21 in the sewage box 20. The wall of the entire sewage straight pipe 21 is smooth, and the flipping surface (input port 211) is designed to form a first angle a1 with the axial direction of the pipeline sewage. The angle range of the first angle a1 is 45°≤a≤60°, so that the sewage straight pipe 21 can be transformed from an upwardly tilted water seal state to a sewage discharge state extending to the rear of the toilet during the 180° flipping process. The potential energy of the flushing water at the brush ring interface is used to realize the normal water seal and horizontal rear sewage discharge function of the wall-mounted toilet 100, with low noise and not easy to hide dirt.

[0066] The sewage box 20 of this embodiment is flattened on the side of the receiving cavity 200 of the toilet 100 for receiving the sewage straight pipe to reduce the thickness of the sewage box 20, and the length of the receiving cavity 200 is greater than the width.

[0067] The sewage box 20 of this embodiment is tilted in the receiving cavity 200 so that the input port 211 is tilted toward the lower front end of the toilet 100, so that the sewage straight pipe 21 can be turned over in a smaller space, thereby achieving the purpose of saving space.

[0068] like Figure 10-15 As shown, when the toilet 100 of the embodiment of the present application is working, when the flushing function is started, water enters the brush ring interface on the toilet body 1 to flush the pot surface of the basin body 11 (see Fig.12 , Fig.13 ), after a certain delay, the sewage discharge straight pipe 21 in the sewage discharge box 20 is turned over by the driving device 22, and the sewage discharge straight pipe 21 rotates to the second working state (refer to Fig.11 ); the water level in the basin 11 of the toilet body 1 is lowered, and the pipe opening of the wall sewage pipe 13 at the rear end is connected through the sewage box 20, and the potential energy of the water is used to discharge the dirt in the basin 11 through the sewage straight pipe 13, thereby playing a sewage discharge role.

[0069] When the sewage discharge action is completed, the sewage discharge straight pipe 21 in the sewage discharge box 20 is reset (restored to the first working state), and the water level in the basin body 11 of the toilet body 1 increases due to the continuous water inflow from the brush ring interface, and the water required for the water seal in the toilet body 1 is replenished ( Fig.14 , Fig.15 When the water level meets the water seal requirement, the water inlet of the brush ring interface is closed, so that the water seal in the toilet body 1 returns to the initial state before the toilet 100 is used (see Fig.10 ).

[0070] The sewage outlet 1110 of the sewage box assembly 2 implemented in the present application is relatively high, which can meet the height matching of the general wall-mounted toilet 100 and can be directly replaced. The sewage straight pipe 21 implemented in the present application has no corners inside, which can better avoid blockage in the sewage discharge process.

[0071] The toilet sewage discharge device 2 implemented in the present application is connected to the toilet body 1 and communicated with the sewage discharge straight pipe 21 in the wall, and is used to discharge waste into the sewage discharge straight pipe 21 in the wall to realize the horizontal rear sewage discharge function (see the arrow direction in the attached figure).

[0072] The toilet sewage discharge device 2 implemented in the present application can effectively reduce the flushing noise during the sewage discharge process and improve the user experience; and can omit the structures such as the injection port, water tank, and booster device in the conventional solution, thereby reducing product costs and simplifying the installation process.

[0073] The sewage box 20 implemented in the present application is provided with a receiving cavity 200, which can prevent dirt from contacting the installation cavity 12, thereby preventing dirt from leaking from the installation cavity 12, and facilitates the installation of other structures in the installation cavity 12, such as a water inlet valve, to save space.

[0074] like Figure 3As shown, the toilet 100 also includes a bracket 3 for hanging the toilet body 1, and the bracket 3 is used to connect the toilet body 1 to the wall and hang the toilet body 1 on the wall. The bracket 3 includes a pair of support legs 30, a connecting cross frame 31 connecting the pair of support legs 30, and a reinforcing cross frame 32. The bottom of the support leg 30 is provided with a support foot 301 for supporting the ground, and the support foot 301 is fixedly connected to the ground by a connecting bolt or screw 302. The support leg 301 is fixedly connected to the wall by a connecting bolt or screw 303. The connecting cross frame 31 is provided with a plurality of hanging rods 310 for hanging the toilet body 1.

[0075] The toilet sewage discharge device 2 implemented in the present application can be installed in the installation cavity 12, and the toilet body 1 does not need to be embedded in the wall, which is different from the solution that the flushing system of the traditional wall-mounted toilet needs to be buried in the false wall. Therefore, when performing maintenance, cleaning and other operations, there is no need to remove the false wall, and the maintenance operation is more convenient. Because the water tank is omitted, the weight and size of the wall-mounted toilet 100 are greatly reduced, so the entire toilet 100 can be supported by an external wall-mounted toilet bracket with a smaller size.

[0076] The toilet 100 of the embodiment of the present application is provided with a bracket 3, which is externally placed on the wall to install the toilet body 1, thereby avoiding the traditional wall-mounted toilet product installation method of chiseling the wall or masonry installation, greatly saving manpower and material costs, and reducing the skill requirements for the installation master. In addition, the external wall-mounted toilet bracket does not need to break the wall and then repair the wall during the subsequent maintenance process, thereby reducing the subsequent maintenance cost.

[0077] In the description of the present application, it should be noted that the terms "upper", "lower", "one side", "the other side", "one end", "the other end", "side", "relative", "four corners", "periphery", "'mouth'-shaped structure" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing 'this' application and simplifying the description, and do not indicate or imply that the referred structure has a specific orientation, is constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0078] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connection", "direct connection", "indirect connection", "fixed connection", "installation", and "assembly" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; the terms "installation", "connection", and "fixed connection" can be a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two components.
