Description

Technical Field

[0001] This invention relates to the field of kitchen and bathroom technology, and more specifically, to an intelligent toilet and its control method. Background Technology

[0002] Existing smart toilets typically use a siphon structure for drainage. The siphon structure's drainage path bends upwards and backwards from the drain outlet in the toilet bowl to a certain height (ensuring a water seal at the bottom of the bowl), then bends downwards to below the drain outlet. This type of smart toilet uses a relatively large amount of water for flushing. One solution is to equip the toilet with a water tank, which supplies water from a pump into the bowl for drainage. This solution ensures the bowl is cleaned with a single flush, but it is costly due to the need for a tank and pump. Another solution is to equip the toilet with a shut-off valve, which allows tap water to be supplied to the bowl for drainage when the valve is closed. This solution is cheaper, but it requires a very high tap water pressure, which is often insufficient to ensure a clean flush. Furthermore, the noise generated during drainage using the siphon structure cannot be minimized. Summary of the Invention

[0016] In some exemplary embodiments, the smart toilet further includes a water supply mechanism, the toilet body also having a water inlet, the water supply mechanism being connected to the toilet cavity through the water inlet and configured to controllably flush water into the toilet cavity.

[0017] In some exemplary embodiments, the smart toilet further includes a wash nozzle disposed at the upper part of the toilet chamber and including the water supply port.

[0018] In some exemplary embodiments, the water inlet is located at the upper part of the toilet cavity, and the toilet body is a toilet body or a washbasin body.

[0019] This invention also provides a control method for a smart toilet, comprising: in response to the smart toilet flushing, first controlling the drive mechanism to drive the rigid pipe to swing from the water seal position to the sewage discharge position, and then controlling the drive mechanism to drive the rigid pipe to swing from the sewage discharge position to the water seal position.

[0023] The technical solution provided by this invention addresses the issue of water and sewage mixture in the toilet chamber. When it is necessary to discharge the mixture, the driving mechanism drives the rigid pipe to swing to the discharge position.

Similarly, the outlet end of the flexible pipe is neither higher than the discharge port, nor is the inlet port higher than the discharge port, and the outlet is neither higher than the inlet port. In this way, the water and sewage mixture in the toilet chamber will quickly pass through the discharge pipe and discharge channel under the natural drop and be discharged into the building pipe. The discharge process of this water and sewage mixture generates less noise and requires less water because the discharge pipe does not have a siphon structure. Moreover, it can ensure that the toilet chamber can be cleaned with a single flush. Furthermore, the sewage... The kinetic energy loss of the water mixture during its passage through the sewage pipe is relatively small, so the conveying capacity of the sewage mixture after flowing out of the sewage pipe by 200 is also relatively strong (which is better suited for the application scenario of toilet relocation installation); after the water mixture is discharged, the drive mechanism drives the rigid pipe to swing to the water seal position. The inlet end of the first pipe section is higher than the sewage outlet, and the outlet end of the corresponding flexible pipe is also higher than the sewage outlet. At this time, the flexible pipe is a bend extending upward from its inlet end to its outlet end. Since there is clean water remaining in the toilet cavity, there is clean water at the bend of the flexible pipe, forming a water seal. In this way, the building pipe will not return odors from the sewage pipe through the sewage outlet into the toilet cavity.

[0024] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0029] The intelligent toilet provided in the embodiments of the present invention, such as Figures 1 to 8 As shown, it includes: a toilet body 100, which has a toilet cavity 110 and a drain outlet 120, the drain outlet 120 being located at the lower part of the toilet cavity 110; a drain pipe 200, which is located outside the toilet cavity 110 and includes a flexible pipe 210 and a bent rigid pipe 220, the rigid pipe 220 including a first pipe section 230 and a second pipe section 240, the drain outlet 120, the flexible pipe 210, the first pipe section 230 and the second pipe section 240 being sequentially and sealed in connection; and a mounting base 300, which has a drain channel with a drain inlet 3. The first pipe section 230 is connected to the discharge port 120 and the outlet 320 of the second pipe section 240, which are rotatably and sealingly connected to the inlet port 360. The inlet port 360 is not higher than the outlet port 120, and the outlet port 320 is not higher than the inlet port 360. The second pipe section 240 is connected to the second pipe section 240 via a drive mechanism 400, which is configured to controllably drive the second pipe section 240 to rotate relative to the inlet port 360. The first pipe section 230 oscillates relative to the inlet port 360 based on the rotation of the second pipe section 240. The rigid pipe 220 has a water seal position and a discharge position. Figure 2 , Figure 3 and Figure 6 As shown, when the drive mechanism 400 drives the rigid pipe 220 to swing to the water seal position, the inlet end of the first pipe section 230 is higher than the drain outlet 120; Figure 7 As shown, when the drive mechanism 400 drives the rigid pipe 220 to swing to the sewage discharge position, the inlet end of the first pipe section 230 is not higher than the sewage discharge port 120 and not lower than the sewage inlet port 360.

[0030] This smart toilet, such as Figure 7 As shown, when the water-sewage mixture in the toilet chamber 110 needs to be discharged, the drive mechanism 400 drives the rigid pipe 220 to swing to the discharge position. At this time, the inlet end of the first pipe section 230 is not higher than the discharge port 120 and not lower than the inlet port 360. Correspondingly, the outlet end of the flexible pipe 210 is not higher than the discharge port 120, and the inlet port 360 is not higher than the discharge port 120, and the discharge port 320 is not higher than the inlet port 360. In this way, the water-sewage mixture in the toilet chamber 110 will be quickly discharged into the building pipe by passing through the discharge pipe 200 and the discharge channel under the natural drop. This process of discharging the water-sewage mixture (that is, the smart toilet) The flushing process (due to the absence of a siphon structure in the drain pipe 200) generates less noise and requires less water, ensuring that the toilet chamber 110 is cleaned in a single flush. Furthermore, the kinetic energy loss of the wastewater mixture during its passage through the drain pipe 200 is minimal, resulting in a stronger transport capacity after the wastewater mixture exits the drain pipe 200 (solving the technical problem of weak transport capacity of the wastewater mixture in the horizontal pipeline after exiting the drain pipe 200, better meeting the application scenarios of same-floor drainage with horizontal pipelines or toilet relocation with horizontal pipelines); after the wastewater mixture is discharged, such as Figure 2 , Figure 3 and Figure 6 As shown, the drive mechanism 400 drives the rigid pipe 220 to swing to the water seal position. The inlet end of the first pipe section 230 is higher than the drain outlet 120, and the outlet end of the corresponding flexible pipe 210 is also higher than the drain outlet 120. At this time, the flexible pipe 210 is a bent pipe that extends upward from its inlet end to its outlet end. Since there is clean water remaining in the toilet chamber 110, there is clean water at the bend of the flexible pipe 210 and a water seal is formed. In this way, the building pipe will not return odor from the drain pipe 200 through the drain outlet 120 into the toilet chamber 110.

[0031] In some embodiments, the outlet end of the flexible tube 210 and the inlet end of the first pipe section 230 are sealed together by means of a connecting thread and a sealing ring, such as... Figure 8 As shown, the inlet end of the flexible pipe 210 and the drain outlet 120 are sealed together by a structure such as a fixing ring 700 and a sealing ring.

[0032] In some examples, such as Figures 2 to 7As shown, the smart toilet also includes: an auxiliary spring 500, a mounting base 300 having a first fixing position 310 located on one side of the second pipe section 240, and a second fixing position 241 provided on the peripheral wall of the second pipe section 240. One end of the auxiliary spring 500 is fixedly connected to the first fixing position 310 and the other end is fixedly connected to the second fixing position 241. The auxiliary spring 500 is configured to generate a driving force to drive the rigid pipe 220 to swing from the sewage position to the water seal position.

[0033] During the swinging process of the rigid pipe 220 from the water seal position to the sewage discharge position driven by the drive mechanism 400, the second pipe section 240 winds around the auxiliary spring 500, causing the auxiliary spring 500 to be stretched and the tension to increase. This slows down the response speed of the rigid pipe 220 swinging from the sewage discharge position to the water seal position, making the sewage mixture discharge process smoother and further reducing the discharge noise of the sewage mixture. During the swinging process of the rigid pipe 220 from the sewage discharge position to the water seal position driven by the drive mechanism 400, the second pipe section 240 gradually releases the auxiliary spring 500, and the auxiliary spring 500, under its own tension... As the length and tension decrease, the auxiliary spring 500 also drives the rigid tube 220 to swing from the sewage position to the water seal position. The tension of the auxiliary spring 500 itself forms the driving force for the rigid tube 220 to swing from the sewage position to the water seal position. In other words, during this process, the auxiliary spring 500 assists the drive mechanism 400 in driving the rigid tube 220 to swing from the sewage position to the water seal position. This can improve the response speed of the rigid tube 220 swinging from the sewage position to the water seal position and reduce the water consumption of the toilet chamber 110 during the discharge of the water-sewage mixture (i.e., the flushing process of the smart toilet is more water-saving).

[0034] It could be that the first fixed bit 310 is one; or it could be, as... Figure 3 and Figure 4 As shown, the first fixing position 310 includes multiple first fixing positions 310, which are arranged sequentially on one side of the second pipe section 240 from the position adjacent to the second pipe section 240 to the position away from the second pipe section 240. One end of the auxiliary spring 500 is fixedly connected to one of the multiple first fixing positions 310, and the other end is fixedly connected to the second fixing position 241. This allows the tension of the auxiliary spring 500 to be adjusted according to actual needs. All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this application. They will not be repeated here, and all should fall within the protection scope of this application.

[0035] In some embodiments, such as Figure 3 , Figures 5 to 7 As shown, one end of the auxiliary spring 500 is fixedly connected to the first fixing position 310 via a mounting bracket, and the other end is hooked to the second fixing position 241.

[0036] In some examples, such as Figures 2 to 7 As shown, the drain outlet 120 is located at the lower rear side of the toilet chamber 110 and is arranged towards the lower rear of the toilet chamber 110. The inlet outlet 360 is located below the drain outlet 120 and is arranged to the left or right. The outlet 320 is located below the inlet outlet 360 and is arranged downwards. Figure 2 , Figure 3 and Figure 6 As shown, when the drive mechanism 400 drives the rigid pipe 220 to swing to the water seal position, the inlet end of the first pipe section 230 is located above and behind the drain outlet 120; Figure 7 As shown, when the drive mechanism 400 drives the rigid pipe 220 to swing to the sewage discharge position, the inlet end of the first pipe section 230 is located below and behind the sewage discharge port 120 and above and behind the sewage inlet port 360. When the wastewater mixture in the toilet chamber 110 needs to be discharged, the drive mechanism 400 drives the rigid pipe 220 to swing to the discharge position. At this time, the inlet end of the first pipe section 230 is located below and behind the discharge port 120 and above and behind the inlet port 360. The outlet end of the corresponding flexible pipe 210 is located below and behind the discharge port 120 and above and behind the inlet port 360. In this way, the wastewater mixture in the toilet chamber 110 first flows downward from front to back through the flexible pipe 210 into the rigid pipe 220, and then flows downward from back to front through the rigid pipe 220 into the discharge channel. After passing through the discharge channel, it is discharged into the building pipe. The discharge process of the wastewater mixture is carried out under natural drop and does not require a siphon structure. Therefore, the discharge process of the wastewater mixture generates less noise and requires less water. In addition, the wastewater mixture is turned 180 degrees as it passes through the flexible pipe 210 and the rigid pipe 220, and 90 degrees as it passes through the rigid pipe 220 and the drain channel. This turning process reduces the flow rate of the wastewater mixture, thus reducing the noise generated during the discharge process. This smart toilet discharges wastewater mixture downwards (suitable for floor-drain installations).

[0037] In some examples, the inlet end of the first pipe segment 230 faces left or right, such as... Figures 2 to 8As shown, the smart toilet also includes: an elbow 600, the outlet end of which is rotatably and sealingly connected to the inlet end of the first pipe section 230, and the inlet end of the elbow 600 is sealedly connected to the outlet end of the flexible pipe 210. Based on the drive mechanism 400 driving the rigid pipe 220 to swing to the water seal position, the inlet end of the elbow 600, under the combined action of its own weight and the force exerted by the flexible pipe 210 on the elbow 600, swings to below the inlet end of the first pipe section 230 and above the drain outlet 120. At this time, the distance between the inlet end of the elbow 600 and the drain outlet 120 is less than the length of the flexible pipe 210, therefore the flexible pipe 210 is in a bent state. This results in a smaller maximum bending angle at the connection point between the flexible pipe 210 and the elbow 600, making it less prone to breakage at the connection point. Based on the drive mechanism 400... When the rigid pipe 220 is driven to swing to the sewage discharge position, the inlet end of the elbow 600 swings to the front and above the inlet end of the first pipe section 230 and forward and upward toward the sewage discharge port 120. At this time, the distance between the inlet end of the elbow 600 and the sewage discharge port 120 is adapted to the length of the flexible pipe 210 (adaptation can be slightly less than, equal to, or slightly greater than). The flexible pipe 120 is in a stretched state. In this way, the height of the passage of the sewage discharge port 120, flexible pipe 210, elbow 600, rigid pipe 220 and sewage inlet 360 gradually decreases, forming a natural drop. The water and sewage mixture can be cleaned in one flush under low water pressure.

[0038] Alternatively, both the first pipe section 230 and the second pipe section 240 may be L-shaped. That is, the rigid pipe 220 formed by connecting the first pipe section 230 and the second pipe section 240 includes a first part arranged in a left-right direction, a second part arranged in a left-right direction, and a third part connecting the first part and the second part. The first part is rotatably and sealingly connected to the sewage inlet 360, and the second part is rotatably and sealingly connected to the elbow 600. Alternatively, the elbow 600, the flexible pipe 210, and the fixing ring 700 may be assembled together as a single integral component.

[0039] In some examples, such as Figures 3 to 5As shown, the peripheral wall of the outlet end of the second pipe section 240 is provided with a sewage outlet 242. The end of the outlet end of the second pipe section 240 is closed and has a rotating connection part 243. The sewage discharge channel is a three-way channel with a sewage inlet 360, a discharge outlet 320, and an installation port 330. The sewage inlet 360 and the installation port 330 are opposite to each other. The outlet end of the second pipe section 240 is rotatably sealed and installed in the sewage inlet 360. The sewage outlet 242 is connected to the discharge outlet 320 inside the three-way channel. The rotating connection part 243 is opposite to the installation port 330. The drive mechanism 400 is connected to the rotating connection part 243 through the installation port 330. In order to prevent the water-sewage mixture from splashing onto the rotating connection part 243 and the drive mechanism 400 during the discharge process and causing dirt and corrosion to the rotating connection part 243 and the drive mechanism 400, the end of the outlet end of the second pipe section 240 is configured to close the installation port 330 inside the three-way channel.

[0040] In some embodiments, such as Figures 3 to 5 As shown, the second pipe section 240 of the rigid pipe 220 is provided with a first hinge part 244 at the bend, and the mounting base 300 is provided with a first hinge mating part. The second pipe section 240 of the rigid pipe 220 is located between the first hinge mating part and the drive mechanism 400. The first hinge part 244 is rotatably connected to the first hinge mating part, and the rotation axis of the first hinge part 244 and the first hinge mating part, the rotation axis of the outlet end of the second pipe section 240 and the sewage inlet 360, and the rotation axis of the drive mechanism 400 and the rotating connection part 243 are collinear. This can better ensure the rotational fit accuracy and rotational sealing performance between the outlet end of the second pipe section 240 and the sewage inlet 360.

[0041] In some embodiments, the first hinge portion 244 is a hinge shaft, and the mounting base 300 is provided with a bearing seat assembly, which includes a first hinge mating portion. This can be, for example... Figures 3 to 5 As shown, the bearing housing assembly includes a bearing housing 340 and a bearing 350. The bearing 350 is installed inside the bearing housing 340, and the first hinged mating part is the inner hole of the bearing 350. The bearing housing 340 can be a split structure. During assembly: it can be that the outlet end of the second pipe section 240 and the inlet 360 are assembled first, then the bearing 350, the hinge shaft and the bearing housing 340 are assembled, and then the drive mechanism 400 and the rotating connection part 243 are assembled; or it can be that the outlet end of the second pipe section 240 and the inlet 360 are assembled first, then the drive mechanism 400 and the rotating connection part 243 are assembled, and then the bearing 350, the hinge shaft and the bearing housing 340 are assembled, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this application, and will not be elaborated here, and should all fall within the protection scope of this application.

[0042] In some embodiments, such as Figure 3 and Figure 4As shown, the drive mechanism 400 is a drive motor. A cover plate 410 is provided on the outer circumference of the drive motor. The drive motor passes through the mounting opening 330 and, together with the cover plate 410, seals the mounting opening 330 outside the three-way channel to prevent dust from entering. The rotation shaft of the drive motor is connected to the rotating connection part 243. The cover plate 410 has a stop protrusion 420. The mounting opening 330 is non-circular. The stop protrusion 420 extends into the mounting opening 330 and abuts against the inner circumferential surface of the mounting opening 330. The stop protrusion 420 prevents the drive motor housing from rotating within the mounting opening 330, thus better ensuring the operational accuracy of the rigid tube 220. The drive motor can be a stepper motor or a servo motor.

[0043] In other examples, the drain outlet 120 is located at the lower rear side of the toilet chamber 110 and is arranged towards the lower rear side of the toilet chamber 110; the inlet outlet 360 is located below the drain outlet 120 and is arranged to the left or right; the discharge outlet 320 is located below the rear side of the inlet outlet 360 and is arranged rearward; the inlet end of the first pipe section 230 faces left or right and is rotatably equipped with an elbow 600. This smart toilet discharges a mixture of water and sewage to the rear (suitable for wall-mounted installation scenarios). The discharge outlet 320 and the inlet outlet 360 may be at the same height; or the discharge outlet 320 may be lower than the inlet outlet 360, etc.; all of the above can achieve the purpose of this application, and their intent does not depart from the design concept of this application, and will not be elaborated further here, all of which should fall within the protection scope of this application. It can be that the sewage channel is a three-way channel; or it can be that the sewage channel is an L-shaped channel (i.e., the sewage channel does not have an installation port 330). In this case, the bend of the second pipe section 240 is provided with a first hinge part 244. The drive mechanism 400 is connected to the first hinge part 244. The rotation axis of the drive mechanism 400 and the first hinge part 244 are collinear with the rotation axis of the outlet end of the second pipe section 240 and the sewage inlet 360, ensuring that the drive mechanism 400 can drive the second pipe section 240 to rotate relative to the sewage inlet 360.

[0044] In some examples, such as Figure 1 and Figure 2 As shown, the smart toilet also includes a water supply mechanism (not shown in the figure). The toilet body 100 also has a water inlet 130. The water supply mechanism is connected to the toilet chamber 110 through the water inlet 130. The water supply mechanism is configured to control the flushing of water into the toilet chamber 110 from the water inlet 130. That is, when the smart toilet receives a control command to flush the toilet chamber 110, the smart toilet controls the water supply mechanism to flush the toilet chamber 110, and the flushing time is set to a third preset time.

[0045] Yes, the control commands can include both defecation and urination flushing commands. The third preset duration for the defecation and urination flushing commands can be the same or different. Alternatively, the third preset duration can be set to a range of 3 to 10 seconds.

[0046] It can be that the water supply system includes a water tank and a water pump; or it can be that the water supply system includes a water pipe and a switch valve, with tap water connected to the switch valve through the water pipe, and the switch valve connected to the water supply port 130. This solution has a very low requirement for the tap water supply pressure (far lower than the minimum tap water supply pressure required by the municipality), which can ensure that the toilet chamber 110 can be cleaned with just one flush, and the cost is also lower.

[0047] In some examples, such as Figure 1 and Figure 2 As shown, the water inlet 130 is located at the upper part of the toilet chamber 110, and the toilet body 100 is either a toilet body or a washbasin body. The inner surface of the flexible tube 210 is a smooth surface, and the outer surface of the flexible tube 210 is provided with spiral reinforcing ribs, which are used to improve the structural strength of the flexible tube 210.

[0048] In some examples, the smart toilet also includes a bidet nozzle, which is installed through the upper part of the side wall of the toilet chamber 110 and includes a water inlet 130, i.e., the water inlet 130 is located on the bidet nozzle.

[0049] The control method for a smart toilet provided in this embodiment of the invention (not shown in the figure) includes: in response to the smart toilet flushing, first controlling the drive mechanism 400 to drive the rigid pipe 220 to swing from the water seal position to the sewage discharge position, and then controlling the drive mechanism 400 to drive the rigid pipe 220 to swing from the sewage discharge position to the water seal position.

[0050] In response to the flushing of the smart toilet, the drive mechanism 400 first drives the rigid pipe 220 to swing from the water seal position to the sewage discharge position. At this time, the inlet end of the first pipe section 230 is not higher than the sewage outlet 120, and the outlet end of the corresponding flexible pipe 210 is also not higher than the sewage outlet 120. The sewage inlet 360 is also not higher than the sewage outlet 120, and the discharge outlet 320 is also not higher than the sewage inlet 360. In this way, the water-sewage mixture in the toilet chamber 110 will quickly pass through the sewage pipe 200 and the sewage discharge channel under the natural drop and be discharged into the building pipes. The discharge process of this water-sewage mixture generates less noise because the sewage pipe 200 does not have a siphon structure. The minimum water consumption required is less; after the sewage mixture is discharged, the drive mechanism 400 drives the rigid pipe 220 to swing from the sewage position to the water seal position (to reset). The inlet end of the first pipe section 230 is higher than the sewage outlet 120, and the outlet end of the corresponding flexible pipe 210 is also higher than the sewage outlet 120. At this time, the flexible pipe 210 is a bent pipe that extends upward from its inlet end to its outlet end. Since there is clean water remaining in the toilet chamber 110, there is clean water at the bend of the flexible pipe 210 and a water seal is formed. In this way, the building pipe will not return odor from the sewage pipe 200 through the sewage outlet 120 into the toilet chamber 110.

[0051] In some embodiments, the steps of first controlling the drive mechanism 400 to drive the rigid pipe 220 to swing from the water seal position to the sewage discharge position, and then controlling the drive mechanism 400 to drive the rigid pipe 220 to swing from the sewage discharge position to the water seal position include: first controlling the drive mechanism 400 to drive the rigid pipe 220 to swing from the water seal position to the sewage discharge position after a first set time period, and then controlling the drive mechanism 400 to drive the rigid pipe 220 to swing from the sewage discharge position to the water seal position after a second set time period.

[0052] In response to the flushing of the smart toilet, the drive mechanism 400 is controlled to drive the rigid pipe 220 to swing from the water seal position to the sewage discharge position after a first set time period, the first set time period being set within the range of 0 to 4 seconds; then, after a second set time period, the drive mechanism 400 is controlled to drive the rigid pipe 220 to swing from the sewage discharge position to the water seal position, the second set time period being set within the range of 2 to 6 seconds. This ensures that the water and sewage mixture in the toilet chamber 110 is completely discharged, and after the rigid pipe 220 swings from the sewage discharge position to the water seal position, clean water remains in the toilet chamber 110, and clean water is present at the bend of the flexible pipe 210, forming a water seal.

[0053] In some embodiments, the step of controlling the drive mechanism 400 to drive the rigid tube 220 to swing from the water seal position to the drain position includes: controlling the drive motor to drive the rigid tube 220 to swing forward by a set angle (the set angle ranges from 5 degrees to 50 degrees), so that the rigid tube 220 swings from the water seal position to the drain position; the step of controlling the drive mechanism 400 to drive the rigid tube 220 to swing from the drain position to the water seal position includes: controlling the drive motor to drive the rigid tube 220 to swing backward by a set angle, so that the rigid tube 220 swings from the drain position to the water seal position. The drive motor is configured as a stepper motor or a servo motor, which has fast response speed and high control precision.

[0054] In some examples, the control method further includes, prior to the flushing step in response to the smart toilet: Obtain a control command to flush the toilet chamber 110; Upon receiving a control command, the water supply mechanism is controlled to flush water from the water inlet 130 into the toilet chamber 110. The water supply mechanism includes a water supply pipe and a switch valve, which is a solenoid valve.

[0055] In some embodiments, the step of controlling the water supply mechanism to flush water into the toilet chamber 110 from the water supply port 130 includes: controlling the water supply mechanism to conduct for a third preset duration, causing the water supply mechanism to flush water into the toilet chamber 110 from the water supply port 130. That is, controlling the switch valve to conduct for a third preset duration, causing the water supply mechanism to flush water into the toilet chamber 110 from the water supply port 130. The third preset duration can be set to a range of 3 to 10 seconds.

[0056] A method for controlling a toilet, comprising: Obtain a control command to flush the toilet chamber 110; Based on the received control command, the water supply mechanism is activated for a third set duration (e.g., 5.5 seconds) to flush water from the water inlet 130 into the toilet chamber 110. After a first set time (e.g., 1.5 seconds), the drive mechanism 400 drives the rigid pipe 220 to swing from the water seal position to the drain position. After a second set time (e.g., 2.5 seconds), the drive mechanism 400 drives the rigid pipe 220 to swing from the drain position to the water seal position. In this way, after the rigid pipe 220 swings from the drain position to the water seal position, the water supply mechanism has not yet finished flushing and continues to supply clean water into the toilet chamber 110 for a period of time equal to the third set time minus the first set time minus the second set time (5.5 seconds - 1.5 seconds - 2.5 seconds = 1.5 seconds). This ensures that clean water remains in the toilet chamber 110, and that clean water is present at the bend of the flexible pipe 210, forming a water seal.

[0057] The present invention also provides a control device for an intelligent toilet, including a processor and a memory storing a computer program, wherein the processor executes the computer program to implement the method described in any of the above embodiments.

[0058] The control device of this smart toilet has all the advantages of the control method provided in any of the above embodiments, and will not be described in detail here.

[0059] The present invention also provides a non-transient computer-readable storage medium storing a computer program executable on a processor. When executed by the processor, the computer program implements the control method described in any of the above embodiments. This non-transient computer-readable storage medium possesses all the advantages of the control method provided in any of the above embodiments, which will not be elaborated further here.

[0060] In summary, the technical solution provided by this invention addresses the issue of discharging a mixture of water and sewage from the toilet chamber. When this occurs, the driving mechanism drives the rigid pipe to swing to the discharge position. At this point, the inlet end of the first pipe section is neither higher than the discharge port nor lower than the inlet port. Similarly, the outlet end of the flexible pipe is neither higher than the discharge port, nor is the inlet port higher than the discharge port, and the outlet is also not higher than the inlet port. This allows the mixture of water and sewage in the toilet chamber to quickly pass through the discharge pipe and discharge channel under natural drop and be discharged into the building's piping system. The discharge process generates less noise and requires less water because the discharge pipe lacks a siphon structure. Furthermore, it ensures that the toilet chamber can be cleaned with a single flush. Furthermore, the kinetic energy loss of the sewage mixture during its passage through the sewage pipe is relatively small, thus the conveying capacity of the sewage mixture after flowing out of the sewage pipe by 200 is also relatively strong (which is better suited for the application scenario of toilet relocation installation); after the sewage mixture is discharged, the drive mechanism drives the rigid pipe to swing to the water seal position, the inlet end of the first pipe section is higher than the sewage outlet, and the outlet end of the corresponding flexible pipe is also higher than the sewage outlet. At this time, the flexible pipe is a bend extending upward from its inlet end to its outlet end. Since there is clean water remaining in the toilet cavity, there is clean water at the bend of the flexible pipe, forming a water seal. In this way, the building pipe will not return odors from the sewage pipe through the sewage outlet into the toilet cavity.
