Toilet and flushing method thereof

Abstract

The present invention provides a toilet and a flushing method thereof. The toilet includes a main body, a connecting pipe, a sewage discharge assembly, and a drive assembly. The main body is provided with a pelvic cavity and a water inlet connected to the pelvic cavity, and a sewage inlet is provided at the bottom of the pelvic cavity. One end of the connecting pipe is connected to the sewage inlet and is movable relative to the main body. One end of the sewage discharge assembly is provided with a sewage discharge outlet, which is connected to the other end of the connecting pipe, and the other end of the sewage discharge assembly is used to communicate with an external sewage discharge channel. The drive assembly is drivably connected to the connecting pipe and can drive the highest position of the connecting pipe to rise or fall relative to the main body. Water and sewage in the pelvic cavity enter the sewage discharge assembly under the action of gravity and siphon force and are discharged into the external sewage discharge channel. The rising and falling of the connecting pipe allows the water and sewage in the pelvic cavity to be discharged to the sewage discharge assembly under the action of gravity, thereby enhancing the sewage discharge effect. There is no need to provide an additional nozzle at the bottom of the pelvic cavity to enhance the sewage discharge effect, thereby reducing the noise during toilet flushing.

Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, in particular to a toilet and a flushing method thereof. Background Art

[0002] A siphonic toilet has a complete pipe, shaped like an inverted "S." The S-bend pipe is typically an integrated ceramic structure. Siphonic toilets have a nozzle at the bottom of the bowl. The water sprayed from the nozzle reduces the amount of air entering the S-bend pipe, enhancing the siphon effect and, consequently, wastewater drainage. However, the nozzle produces a considerable amount of noise during the flushing process, which can be quite noisy. Summary of the Invention

[0010] When the connecting pipe is in an initial state, the highest point of the connecting pipe is at a first height, so that a first water seal surface can be formed in the pelvic cavity;

[0011] When the driving assembly drives the highest position of the connecting pipe to rise, so that the connecting pipe is in the water storage state, the highest point of the connecting pipe is at a second height, and the second height is higher than the first height, so that a second water cover can be formed in the pelvic cavity, and the height of the second water cover is higher than the height of the first water cover;

[0053] It can be seen from the above technical solutions that the present invention has at least the following advantages and positive effects:

[0054] In the present invention, when flushing, the drive assembly drives the connecting pipe to rise. External water enters the pelvic cavity through the water inlet, causing the water level in the pelvic cavity to rise. When the water level in the pelvic cavity reaches a preset water level, the drive assembly drives the connecting pipe to descend. Under the action of gravity and siphon force, the water and dirt in the pelvic cavity enter the sewage discharge assembly and are discharged to the external sewage discharge channel. By rising and falling the connecting pipe, the water and dirt in the pelvic cavity can be discharged to the sewage discharge assembly under the action of gravity, thereby enhancing the sewage discharge effect. There is no need to set an additional nozzle at the bottom of the pelvic cavity to enhance the sewage discharge effect, thereby reducing the noise when the toilet is flushing.

[0087] In one embodiment, if Figure 1 and Figure 2 As shown, a toilet includes a main body 100, a connecting pipe 200, a sewage discharge assembly 300 and a drive assembly 400. Specifically, the main body 100 can be made of ceramic. The main body 100 is placed on a floor 500.

[0088] In one embodiment, the main body 100 is provided with a pelvic cavity 110 and a water inlet 120 connected to the pelvic cavity 110. The water inlet 120 is connected to an external tap water pipe. When flushing is required, the external tap water pipe is turned on. External water enters the pelvic cavity 110 through the water inlet 120, flushing and cleaning the pelvic cavity 110. Specifically, the water inlet 120 is located on the inner edge of the main body 100.

[0089] In one embodiment, please refer to Figure 7 A sewage inlet 130 is provided at the bottom of the pelvic cavity 110. One end of the connecting pipe 200 is connected to the sewage inlet 130. One end of the connecting pipe 200 is connected to the pelvic cavity 110. Dirt and water in the pelvic cavity 110 can enter the connecting pipe 200 through the sewage inlet 130. Specifically, one end of the connecting pipe 200 and the sewage inlet 130 can be detachably connected. That is, the connecting pipe 200 and the main body 100 can be detachable.

[0090] In one embodiment, please refer to Figure 4 A sewage outlet 310 is provided at one end of the sewage discharge assembly 300. The height of the sewage outlet 310 is lower than that of the sewage inlet 130, so that the sewage and water in the sewage inlet 130 have gravitational potential energy.

[0091] The sewage outlet 310 is connected to the other end of the connecting pipe 200. Specifically, the other end of the connecting pipe 200 is detachably connected to the sewage outlet 310. That is, the connecting pipe 200 and the sewage discharge assembly 300 are detachable structures.

[0092] In the related art, the main body, S-bend and sewage assembly of the siphonic toilet are an integrated structure. During installation, the sewage assembly needs to be aligned with the external sewage channel, that is, the sewer. Since the three are all integrated structures. During the alignment process, the main body and the S-bend also need to be moved synchronously. The main body is a very heavy ceramic structure, which makes the entire installation difficult. In this embodiment, the sewage assembly 300 can be aligned and connected with the external sewage channel alone without the need to synchronously move the heavy main body 100 for alignment, and then move the main body 100 to the sewage assembly 300, and finally connect the main body 100 and the sewage assembly 300 through the connecting pipe 200, thereby reducing the difficulty of installation.

[0093] In one embodiment, the other end of the drain assembly 300 is connected to an external drain channel. Specifically, the connecting pipe 200 connects the sewage inlet 130 and the drain outlet 310, preventing external air from entering the connecting pipe 200 and enhancing the siphon effect. Under the action of the siphon force, waste in the connecting pipe 200 enters the drain outlet 310 and the drain assembly 300, and is discharged through the drain assembly 300 into the external drain channel.

[0094] In this embodiment, the connecting pipe 200 is movable relative to the main body 100. The driving assembly 400 is driven and connected to the connecting pipe 200, and is capable of driving the highest position of the connecting pipe 200 to rise or fall relative to the main body 100, so that the connecting pipe 200 is in the initial state, the water storage state and the sewage discharge state, respectively. When flushing, the driving assembly 400 drives the highest position of the connecting pipe 200 to rise. External water enters the pelvic cavity 110 through the water inlet 120, causing the water level in the pelvic cavity 110 to rise. When the water level in the pelvic cavity 110 reaches the preset water level, the driving assembly 400 drives the connecting pipe 200 to descend. The water and dirt in the pelvic cavity 110 enter the sewage discharge assembly 300 under the action of gravity and siphon force and are discharged to the external sewage discharge channel. By rising and falling the connecting pipe 200, the water and dirt in the basin 110 can be discharged to the sewage discharge assembly 300 under the action of gravity, thereby enhancing the sewage discharge effect. There is no need to set an additional nozzle at the bottom of the basin 110 to enhance the sewage discharge effect, thereby reducing the noise when the toilet is flushing and solving the problem of backflow after flushing.

[0095] Specifically, the connecting pipe 200 has a water storage state ( Figure 8 and Figure 9 shown) and sewage status ( Figure 10 and Figure 11). When the connecting pipe 200 is in the water storage state, the angle between the connecting pipe 200 and the horizontal plane is 90°, that is, the connecting pipe 200 is perpendicular to the horizontal plane. The highest point of the connecting pipe 200 is higher than the height of the sewage outlet 310, so that a water cover is formed in the pelvic cavity 110. When the connecting pipe 200 is in the sewage discharge state, the connecting pipe 200 has a downward angle, and the height of the connecting pipe 200 is lower than the height of the sewage outlet 310, so that the water in the pelvic cavity 110 can enter the sewage discharge assembly 300 through the connecting pipe 200. The driving assembly 400 drives the connecting pipe 200 to rise or fall, so that the connecting pipe 200 switches between the water storage state and the sewage discharge state.

[0096] Please refer to Figure 6 and Figure 7 , the angle between the connecting pipe 200 and the horizontal plane is approximately 60°, and this position is the initial state of the connecting pipe 200. When flushing is required, the driving component 400 drives the connecting pipe 200 to rise, increases the water level of the connecting pipe 200, and increases the water storage capacity of the pelvic cavity 110. This position is the water storage state of the connecting pipe 200. Turn on the external tap water pipe to flush water into the pelvic cavity 110. When the water level in the pelvic cavity 110 reaches a preset height, the driving component 400 drives the connecting pipe 200 to descend, and the connecting pipe 200 has a downward tilt angle. At this time, the connecting pipe 200 is in a sewage discharge state, so that the water and dirt in the pelvic cavity 110 enter the sewage outlet 310 under their own gravity.

[0097] In this embodiment, please refer to Figure 2 The connecting pipe 200 includes a first connecting pipe section 210, a second connecting pipe section 220, and a sewage pipe section 230 disposed between the first connecting pipe section 210 and the second connecting pipe section 220. The two ends of the first connecting pipe section 210 are respectively connected to one end of the sewage pipe section 230 and the sewage inlet 130. The two ends of the second connecting pipe section 220 are respectively connected to the other end of the sewage pipe section 230 and the sewage outlet 310. The driving assembly 400 is drivingly connected to the sewage pipe section 230, and the sewage pipe section 230 is movably arranged relative to the first connecting pipe section 210 and the second connecting pipe section 220. The sewage pipe section 230 can be a rigid pipe with a bending structure, and the first connecting pipe section 210 and the second connecting pipe section 220 can both be elastic flexible joints. The first connecting pipe section 210 and the pelvic cavity 110 can be fixedly connected at the sewage inlet 130, and the second connecting pipe section 220 and the sewage assembly 300 can be fixedly connected at the sewage outlet 310. The entire rigid pipe can move relative to the elastic flexible joint. The driving assembly 400 drives the entire rigid pipe to rise or fall. Specifically, the driving assembly 400 drives the sewage pipe section 230 to rise or fall.

[0098] Specifically, the toilet also includes a protective sleeve that is mounted on the outer periphery of the connecting pipe 200. Specifically, the protective sleeve is mounted on the sewage pipe section 230. The drive assembly 400 is drivingly connected to the protective sleeve. The provision of the protective sleeve can reduce the degree of wear on the connecting pipe 200 during rotation, thereby extending the service life of the connecting pipe 200.

[0099] In another embodiment, connecting pipe 200 can be a flexible pipe. In related art, the ceramic structure of the S-bend pipe integrated with the toilet bowl is complex to manufacture and requires glazing during the manufacturing process, which can easily lead to uneven glazing and difficulty in inspection. Flexible pipes are not ceramic and do not require glazing, which can reduce manufacturing costs.

[0100] In this embodiment, please refer to Figure 2 and Figure 3 , the driving assembly 400 includes a motor 410 and a rotating arm 420. The motor 410 is driven and connected to the rotating arm 420. The rotating arm 420 is rotatably connected to the connecting pipe 200. The rotating arm 420 rotates up and down to drive the highest point of the connecting pipe 200 to rise and fall. Specifically, the rotating arm 420 is connected to the sewage pipe section 230, and the rotating arm 420 drives the sewage pipe section 230 to rotate relative to the main body 100. In another embodiment, the driving assembly 400 may also include a cylinder and a connecting rod. The cylinder is driven and connected to the connecting rod. The end of the connecting rod away from the cylinder is connected to the connecting pipe 200. The connecting rod is driven by the cylinder to perform linear motion in the vertical direction, so that the connecting rod drives the connecting pipe to rise or fall. Specifically, the connecting rod can be, but is not limited to, a telescopic rod.

[0101] In one embodiment, the rotating arm 420 includes two connecting ends and a bend 424 provided at the two connecting ends. The bend 424 bends toward one side of the connecting tube 200. Specifically, the bend 424 bends toward the middle of the connecting tube 200. In actual product design, the rotating arm 420 cannot be directly designed in the middle of the connecting tube 200. If the rotating arm 420 is configured as a straight rod, the connection between the rotating arm 420 and the connecting tube 200 will be located to the left or right of the connecting tube 200, resulting in uneven force on the connecting tube 200 when the rotating arm 420 drives the connecting tube 200 to rise or fall. The bend 424 can make the connection between the rotating arm 420 and the connecting tube 200 offset toward the middle of the connecting tube 200, making the force on the connecting tube 200 more balanced and allowing the connecting tube 200 to rise or fall stably.

[0102] like Figure 6 and Figure 7As shown, the connecting pipe 200 is in the initial state, that is, the state in which the toilet is not in use. The angle between the connecting pipe 200 and the horizontal plane is 60 degrees. The motor 410 drives the rotating arm 420 to rotate 30 degrees in the counterclockwise direction, and the rotating arm 420 drives the connecting pipe 200 to rotate 30 degrees in the counterclockwise direction, so that the angle between the connecting pipe 200 and the horizontal plane is 90 degrees, as shown in FIG. Figure 9 As shown. That is, the rotating arm 420 drives the connecting pipe 200 to rise, so that the connecting pipe 200 is in a water storage state. The motor 410 drives the rotating arm 420 to rotate slightly more than 90 degrees in the clockwise direction, as shown. Figure 11 As shown, the connecting pipe 200 has a downward tilt angle. That is, the rotating arm 420 drives the connecting pipe 200 to descend, so that the connecting pipe 200 is in a sewage discharge state. The clockwise direction and counterclockwise direction in this article are both Figure 7 、 Figure 9 and Figure 11 For reference.

[0103] In one embodiment, please refer to Figure 3 The toilet also includes a base 600. A rotating shaft 430 is rotatably provided on the base 600. Specifically, a first support seat 610 and a second support seat 620 are provided on the base 600. The first support seat 610 and the second support seat 620 are arranged opposite to each other. The rotating shaft 430 is rotatably provided between the first support seat 610 and the second support seat 620. More specifically, the first support seat 610 is provided with a first through hole. The second support seat 620 is provided with a second through hole opposite to the first through hole. The rotating shaft 430 is rotatably provided in the first through hole and the second through hole.

[0104] In one embodiment, the motor 410 is mounted on a base 600. The motor 410 is fixedly mounted on the base 600. The base 600 is capable of supporting the motor 410. The motor 410 is drivingly connected to a rotating shaft 430. Specifically, an output shaft at one end of the motor 410 is drivingly connected to the rotating shaft 430. One end of the rotating arm 420 is connected to the rotating shaft 430, and the other end is connected to the connecting tube 200.

[0105] In this embodiment, please refer to Figure 3 , a protrusion 630 is provided on the base 600. The protrusion 630 is provided between the first support seat 610 and the second support seat 620. The protrusion 630 is located directly below the rotation axis 430. Specifically, the protrusion 630 can be a plate-shaped structure or a block-shaped structure.

[0106] In one embodiment, please refer to Figure 5 , a first limiting portion 421 is provided at one end of the rotating arm 420 close to the base 600. The first limiting portion 421 may be a protrusion extending along the length direction of the rotating arm 420. Figure 5As shown in FIG. , the first stopper 421 is positioned to the right of the central axis of the rotating arm 420. When the rotating arm 420 rotates clockwise until it is perpendicular to the horizontal plane, the first stopper 421 abuts against the raised portion 630, restricting further clockwise rotation of the rotating arm 420 and thereby limiting the rotation range of the rotating arm 420. The cooperation between the first stopper 421 and the raised portion 630 limits the clockwise rotation of the rotating arm 420, thereby restricting the clockwise rotation of the connecting pipe 200.

[0107] In one embodiment, please refer to Figure 5 A second limiting portion 422 is further provided at one end of the rotating arm 420, which is close to the base 600. The second limiting portion 422 is provided on the side of the rotating arm 420 that faces away from the sewage inlet 130. That is, the second limiting portion 422 is a protrusion extending along the width direction of the rotating arm 420. When the rotating arm 420 rotates counterclockwise until the connecting tube 200 tilts downward, the second limiting portion 422 can abut against the protrusion 630 to limit the rotating arm 420 and thus limit the rotation range of the rotating arm 420. Through the cooperation between the second limiting portion 422 and the protrusion 630, the rotating arm 420 can be limited to rotate in the counterclockwise direction, thereby limiting the counterclockwise rotation of the connecting tube 200.

[0108] The first stopper 421 and the second stopper 422 cooperate to allow the connecting pipe 200 to rotate at a preset angle, thereby controlling the rising and falling height of the connecting pipe 200. This ensures that the water level in the pelvic cavity 110 remains at a preset height when the connecting pipe 200 is in the water storage state. Furthermore, this ensures that the connecting pipe 200 is tilted downward in the sewage discharge state, allowing the sewage and water in the sewage outlet 310 to flow into the sewage outlet 310 under the action of gravity.

[0109] In one embodiment, a retaining portion 423 is provided at one end of the rotating arm 420 away from the base 600. The retaining portion 423 can retain the connecting tube 200. The retaining portion 423 can be a slot into which the connecting tube 200 is retained. The retaining portion 423 can also be a circular structure to accommodate the shape of the connecting tube 200.

[0110] In this embodiment, the toilet further includes a flow meter 700 and a solenoid valve 710. The flow meter 700 is connected to the solenoid valve 710, and the flow meter 700 is used to measure the amount of water entering the pelvic cavity 110. The solenoid valve 710 is respectively connected to the water inlet 120 and the external water source. The flow meter 700 is electrically connected to the solenoid valve 710 and the drive assembly 400. When the connecting pipe 200 moves from the initial state to the water storage state, when water is stored in the pelvic cavity 110, the flow meter 700 is used to measure the amount of stored water. When the water storage reaches a preset value, the solenoid valve 710 is closed, and the drive assembly 400 drives the connecting pipe 200 to rotate, switching to the sewage discharge state.

[0111] In one embodiment, the toilet further includes an angle sensor 720. The angle sensor 720 is electrically connected to the drive assembly 400. The angle sensor 720 is used to sense the rotation angle of the connecting tube 200. When the angle information reaches a first angle, a second angle, and a third angle, the drive assembly 400 stops driving the connecting tube 200 to rotate. For example, the first angle may be 60°, the second angle may be 90°, and the third angle may be 0°. Specifically, the angle sensor 720 is used to sense the rotation angle of the drive shaft of the drive assembly 400 and obtain the angle information of the drive shaft.

[0112] Specifically, the angle sensor 720 may be a Hall effect angle sensor. The motor 410 and the rotating shaft 430 can be driven by a worm 730 and a gear assembly 740. The output shaft of the motor 410 is drivingly connected to the worm 730. The worm 730 meshes with the gear assembly 740. The rotating shaft 430 is connected to the gear assembly 740. The motor 410 drives the worm 730 to rotate, which in turn drives the gear assembly 740, which in turn drives the rotating shaft 430. The worm 730 and gear assembly 740 also have a self-locking function. When the connecting tube 200 is in the initial state, at a first angle, the worm 730 and gear assembly 740 lock the connecting tube 200, preventing it from falling due to its own weight. A magnet 750 is fixedly mounted within the rotating shaft 430. The magnet 750 rotates synchronously with the rotating shaft 430. The Hall angle sensor is disposed close to the magnet 750 , and can detect the rotation angle of the magnet 750 , thereby detecting the rotation angle of the rotating shaft 430 .

[0113] In one embodiment, the toilet further includes a controller electrically connected to the drive assembly 400 and configured to identify a full flush signal and a light flush signal. For example, a long press of the flush button triggers a full flush signal, while a short press of the flush button triggers a light flush signal.

[0114] When the controller receives the high-pressure signal, the drive assembly 400 drives the connecting pipe 200 to switch from the initial state to the water storage state. The drive assembly 400 then drives the connecting pipe 200 to switch from the water storage state to the sewage discharge state. After the sewage is discharged, the drive assembly 400 drives the connecting pipe 200 to switch from the sewage discharge state to the initial state.

[0115] When the controller receives a low-flushing signal, the drive assembly 400 drives the connecting tube 200 from its initial state to its drainage state. After drainage is complete, the drive assembly 400 drives the connecting tube 200 from its drainage state to its initial state. Users can control water consumption by using high and low flushes. For example, if there is little dirt in the pelvic cavity 110 and flushing is sufficient without the need for a water storage process, the low flush process can be selected, which not only saves water but also reduces noise.

[0116] In other embodiments, the toilet further includes a flush button and a small flush button, which are electrically connected to the drive assembly 400. The flush button can send a flush signal to the drive assembly 400 to cause the drive assembly 400 to perform a flush operation. The small flush button can send a small flush signal to the drive assembly 400 to cause the drive assembly 400 to perform a small flush operation.

The angle information of the connecting pipe can correspond to the height of the connecting pipe. By obtaining the angle information of the connecting pipe, the connecting pipe can stay at the preset height.

[0124] S300, storing water in the pelvic cavity to form a second water cover.

[0125] S400: The driving assembly drives the connecting pipe in the water storage state to descend to a third height, which is lower than the height of the sewage inlet, and the connecting pipe switches from the water storage state to the sewage discharge state.

[0126] Specifically, if Figure 18 As shown, the step of the driving assembly driving the connecting pipe in the water storage state to descend to the third height includes:

[0127] S410: Start the driving assembly, and the driving assembly drives the connecting pipe in the water storage state to rotate.

[0128] S420: Obtain angle information of the connection pipe rotation.

[0129] S430: When the angle information reaches a third angle, the connecting pipe descends to a third height.

[0133] S500, sewage discharge is completed, the driving component drives the connecting pipe in the sewage discharge state to rise to a first height, water is stored in the pelvic cavity, a first water cover is formed, and the connecting pipe is switched from the sewage discharge state to the initial state.

[0134] More specifically, if Figure 20 As shown, the step of driving the connecting pipe to rise to the first height by the driving assembly further includes:

[0135] S510: Start the driving assembly, and the driving assembly drives the connecting pipe in the sewage discharge state to rotate.

[0143] S250: When the flushing signal is a small flushing signal, the driving component drives the connecting pipe to directly switch from the initial state to the sewage discharge state.

[0144] S260: When the flush signal is a high flush signal, the drive assembly drives the connecting pipe to switch from the initial state to the water storage state, and then from the water storage state to the sewage discharge state. The low flush not only saves water but also reduces noise.
