Description

TECHNICAL FIELD

[0001] The present application relates to, but is not limited to, the technical field of sanitary wares, and in particular to a decontamination control method, a decontamination control device, and a toilet. BACKGROUND

[0002] At present, the toilets on the market are basically tankless toilets that use municipal water pressure to realize circle flushing and decontamination jet flushing through a two-way valve, or tank toilets that use a water pump to pump water to realize circle flushing and decontamination jet flushing through waterway switching, thereby realizing the decontamination function. Both of these two decontamination methods need to first open the top circle waterway to clean the ceramic pot surface, and then switch to the bottom jet waterway to realize decontamination through jetting. The overall waterway structure is complex, and the entire decontamination flushing process is long and water consumption is large. SUMMARY

[0003] The present application provides a decontamination control method, a decontamination control device, and a toilet, which can simplify the waterway structure of the toilet and shorten the decontamination flushing time, thereby reducing water consumption.

[0004] The present application provides a decontamination control method applied to a toilet, wherein the toilet comprises a toilet seat body, a circle flushing device, a decontamination pipe, and a driving device; the decontamination pipe is in communication with a decontamination outlet of the toilet seat body, the driving device is connected to the decontamination pipe and is arranged to drive the decontamination pipe to rotate relative to the toilet seat body between a water replenishing position and a decontamination position; the decontamination control method comprises:

[0005] determining a target decontamination flushing mode, wherein the determination factors of the target decontamination flushing mode include at least one of a decontamination scene and a decontamination water consumption;

[0006] controlling the circle flushing device and the driving device according to the target decontamination flushing mode.

[0007] The toilet cancels the traditional siphon pipe decontamination flushing mode, adopts a turnover decontamination mode, and uses the natural gravity falling mode to discharge the contaminants in the toilet from the toilet pot surface and the toilet pipe. During the decontamination process, the decontamination pipe rotates around the rotation axis to perform dumping decontamination, and the contaminants in the toilet pot surface are efficiently and quickly discharged through the decontamination pipe under the action of gravity and dumping inertia.

[0008] Since the toilet realizes sewage discharge by overturning and discharging, it does not need the strong water flow impact of the bottom jet waterway, so the toilet cancels the jet waterway at the bottom of the conventional toilet and only retains the brush circle waterway at the top, thereby simplifying the waterway structure of the toilet. The brush circle flushing device discharges water to meet the cleaning demand of the pot surface and the discharge demand of the sewage. Since the discharge of the sewage mainly utilizes gravity and falling inertia, it does not need the continuous impact of a large amount of water of the bottom jet waterway in the traditional way, and thus is beneficial to water saving; and the cleaning process of the pot surface and the discharge process of the sewage can be selected to be performed synchronously, and thus the cleaning water of the pot surface can also be used for the sewage discharge process, and thus is also beneficial to water saving.

[0009] Moreover, the control method provided by the embodiment of the present application can first determine a target sewage flushing mode, and then control the brush circle flushing device and the driving device according to the target sewage flushing mode. The determination factors of the target sewage flushing mode can include at least one of a sewage discharge scene and a sewage discharge water amount. In this way, the target sewage flushing mode can be classified according to the sewage discharge scene, or can be classified according to the sewage discharge water amount, or can be classified according to the sewage discharge scene and the sewage discharge water amount, which is beneficial to the diversification and intelligentization of the sewage flushing function, and thus is beneficial to meeting the sewage flushing demand of different scenes, taking into account the water saving concept and the individualized demand of the user.

[0010] The embodiment of the present application also provides a sewage control device, characterized by comprising a processor and a memory storing a computer program, and the processor implements the steps of the sewage control method according to the computer program.

[0011] The embodiment of the present application also provides a toilet comprising the sewage control device according to the above embodiment.

[0026] This application provides a sewage control method applied to toilets.

[0027] like Figures 1 to 3 As shown, the toilet includes a toilet seat 1, a brush ring flushing device 2, a drain pipe 3, and a drive device. The toilet seat 1 has a basin cavity, and a portion of the inner wall of the basin cavity is a pot surface 11. The space enclosed by the pot surface 11 is used to store water, forming a water seal. The bottom of the pot surface 11 has a drain outlet 12, which is connected to the drain pipe 3. The brush ring flushing device 2 includes a water circuit switch valve 21 and a flow meter 22. The water circuit switch valve 21 controls the water intake of the pot surface 11 by opening and closing, realizing the brush ring cleaning of the ceramic pot surface 11, draining, and water seal replenishment. The water circuit switch valve 21 has a flow meter 22 to control the water intake flow, realizing intelligent and stable water supply under different pressures. Water replenishment can be controlled by the flow meter 22, which is not affected by the user's water pressure, and can accurately replenish water, avoiding waste of high-pressure water. The toilet may also include a drain box 5, with the drain pipe 3 at least partially located inside the drain box 5, and the outlet of the drain box 5 connected to the external drain pipe 3.

[0028] The drive unit is connected to the drain pipe 3 and is configured to drive the drain pipe 3 to rotate relative to the toilet seat 1 between the water filling position and the drain position. The drive unit may include a drive component (such as a drive motor) and a transmission mechanism. The transmission mechanism may be, but is not limited to, a gearbox assembly 4. The gearbox assembly 4 is connected to the drain pipe 3 and can drive the drain pipe 3 to rotate under the drive of the drive component. The drive component may be a forward and reverse drive component, so that the drain pipe 3 can rotate in both directions.

[0029] When drain pipe 3 is in the water filling position, the drain outlet of drain pipe 3 faces upward (it can be horizontally upward or tilted upward) to ensure a water seal is formed in the toilet. When drain pipe 3 is in the waste discharge position, the drain outlet of drain pipe 3 faces downward (it can be horizontally downward or tilted downward) to ensure waste can be discharged. Figure 3 In the diagram, the solid line indicates the drain pipe 3 in the water replenishment position, while the dashed line indicates the drain pipe 3 in the sewage discharge position.

[0030] The toilet cancels the traditional siphon pipe flushing mode, adopts the overturning flushing mode, and uses the natural gravity falling mode to discharge the dirt in the toilet bowl to the toilet pot surface 11 and the toilet pipe. During the flushing process, the flushing pipe 3 rotates around the rotation axis to perform the dumping flushing, and under the action of gravity and the dumping inertia, the dirt in the toilet pot surface 11 is efficiently and quickly discharged through the flushing pipe 3.

[0031] Since the toilet adopts the overturning flushing mode to realize the flushing, the strong water flow impact of the bottom jet waterway is not needed, and therefore the toilet cancels the bottom jet waterway of the conventional toilet and only retains the top circle flushing waterway, thereby simplifying the waterway structure of the toilet. The circle flushing device 2 is used to discharge water to meet the cleaning demand of the pot surface 11 and the discharge demand of the dirt. Since the discharge of the dirt mainly uses gravity and the dumping inertia, the continuous impact of a large amount of water of the bottom jet waterway in the conventional mode is not needed, and therefore it is beneficial to save water; and the cleaning process of the pot surface 11 and the discharge process of the dirt can be selected to be performed synchronously, and the waterway does not need to be switched to be performed respectively, and therefore the water used for cleaning the pot surface 11 can also be used for the flushing process, and therefore it is also beneficial to save water.

[0032] As shown in FIG. 1, Figure 4 the flushing control method comprises the following steps.

[0033] Step S202: determining a target flushing mode, and the determination factors of the target flushing mode include at least one of a flushing scene and a flushing water amount;

[0034] Step S204: controlling the circle flushing device 2 and the driving device according to the target flushing mode.

[0035] The control method provided by the embodiment can first determine the target flushing mode, and then control the circle flushing device 2 and the driving device according to the target flushing mode. The determination factors of the target flushing mode can include at least one of the flushing scene and the flushing water amount. In this way, the target flushing mode can be classified according to the flushing scene, or can be classified according to the flushing water amount, or can be classified according to the flushing scene and the flushing water amount, which is beneficial to realize the diversification and intelligentization of the flushing function, and therefore is beneficial to meet the flushing demand of different scenes, and take into account the water saving concept and the individualized demand of the user.

[0036] In some exemplary embodiments, the determination method of the target flushing mode comprises at least one of the following ways:

[0037] determining the target flushing mode according to the received external input instruction information;

[0038] automatically determining the target flushing mode according to internal detection information.

[0039] The target flushing mode can be determined according to the external input instruction information received by the system, so that the user can freely select the flushing mode according to his own needs, thereby facilitating the satisfaction of the personalized needs of the user. The input method of the instruction information is not limited, for example, the input can be through the remote control of the toilet, the input can also be through voice, or the input can be through the APP of a mobile terminal (such as a mobile phone).

[0040] The target flushing mode can also be automatically determined according to internal detection information, so that the user does not need to select, and the toilet can automatically determine the appropriate flushing mode, thereby improving the intelligence and automation of the toilet, and facilitating the improvement of the user experience.

[0041] In some exemplary embodiments, the toilet flushing control method further comprises: determining that the user has finished defecating. Based on the user having finished defecating, the step of automatically determining the target flushing mode according to the internal detection information is performed.

[0042] In this way, the user can avoid executing the flushing process during the defecation process, thereby avoiding the adverse experience of the user during the defecation process.

[0043] For example, for the case where the toilet does not have an automatic cover closing function: based on detecting the off-seat signal and the off-seat time being greater than or equal to the set off-seat time, it is determined that the user has finished defecating.

[0044] For example, for the case where the toilet has an automatic cover closing function and the automatic cover closing function cannot be closed: based on detecting the off-seat signal and the cover closing signal in sequence, it is determined that the user has finished defecating.

[0045] For example, for the case where the toilet has an automatic cover closing function and the automatic cover closing function can be selected to be opened or closed: 1) based on the automatic cover closing function being in the closed state, detecting the off-seat signal and the off-seat time being greater than or equal to the set off-seat time, it is determined that the user has finished defecating; 2) based on the automatic cover closing function being in the open state, detecting the off-seat signal and the cover closing signal in sequence, it is determined that the user has finished defecating.

[0046] The automatic cover closing function refers to the ability of the toilet cover to automatically close after the user leaves the seat, without the user manually closing the toilet cover. The toilet cover can be set to close with a delay, for example, when the off-seat time reaches the set off-seat time, the toilet cover automatically closes. When this function is closed, the toilet cover cannot automatically close and needs to be manually closed. The set off-seat time can be in the range of but not limited to 5s to 15s. The set cover closing time can be in the range of but not limited to 5s to 15s.

[0047] In some example embodiments, the determining factor of the target flushing mode includes a defecation scenario. The target flushing mode determined according to the defecation scenario includes at least one of a large flush mode and a small flush mode.

[0048] The defecation scenario generally includes a defecation scenario and a urination scenario, and accordingly, the target flushing mode can include a large flush mode and a small flush mode. Generally, the water consumption for urination can be less than the water consumption for defecation. Therefore, by distinguishing the flushing mode according to the defecation scenario into a large flush mode and a small flush mode, it can be avoided that the water consumption for defecation is also used for the urination scenario, thereby being conducive to reducing the water consumption for the urination scenario and being conducive to saving water resources.

[0049] In some example embodiments, the target flushing mode is determined according to the received instruction information of the external input, including:

[0050] Based on receiving a large flush instruction of the external input, the target flushing mode is determined as the large flush mode;

[0051] Based on receiving a small flush instruction of the external input, the target flushing mode is determined as the small flush mode.

[0052] For example, after the user finishes defecation (of course, not limited to after finishing defecation, but also other scenarios, such as pouring other pollutants, such as vomit, into the toilet), the user can press the large flush button through the remote controller, and the system can receive the large flush instruction of the external input, and can determine the target flushing mode as the large flush mode. Alternatively, the user can issue a large flush instruction through voice, and the voice collection module of the toilet can receive the large flush instruction, thereby determining the target flushing mode as the large flush mode. Alternatively, the user can select the large flush mode through the APP of the mobile terminal (such as a mobile phone), and the machine can receive the large flush instruction sent by the APP through wireless network, Bluetooth, or other communication methods, and can determine the target flushing mode as the large flush mode.

[0053] After the user finishes urination (of course, not limited to after finishing urination, but also other scenarios, such as pouring other pollutants, such as laundry water, into the toilet), the user can press the small flush button through the remote controller, and the machine can receive the small flush instruction of the external input, and can determine the target flushing mode as the small flush mode. Alternatively, the user can issue a small flush instruction through voice, and the voice collection module of the toilet can receive the small flush instruction, thereby determining the target flushing mode as the small flush mode. Alternatively, the user can select the small flush mode through the APP of the mobile terminal (such as a mobile phone), and the machine can receive the small flush instruction sent by the APP through wireless network, Bluetooth, or other communication methods, and can determine the target flushing mode as the small flush mode.

[0054] In some example embodiments, the internal detection information comprises off- flush related information. Automatically determining the target flush mode according to the internal detection information comprises: determining the target flush mode according to the off- flush related information. This solution can be applied to a toilet without an automatic lid closing function or a toilet with an automatic lid closing function that cannot be selected to be opened or closed.

[0055] Alternatively, the internal detection information comprises an open or close state of an automatic lid closing function and off- flush related information. Automatically determining the target flush mode according to the internal detection information comprises: based on the automatic lid closing function being in a closed state, determining the target flush mode according to the off- flush related information. This solution can be applied to a toilet with an automatic lid closing function that can be selected to be opened or closed.

[0056] The off- flush related information corresponds to a judgment factor in the off- flush judgment logic. During the user's toilet process, the system can detect the off- flush related information, so as to automatically determine the target flush mode according to the off- flush judgment logic after determining that the user has left the seat after the user's toilet is completed.

[0057] In some example embodiments, the off- flush related information comprises a sitting duration, and whether a hip washing function is operated. Automatically determining the target flush mode according to the off- flush related information comprises:

[0058] Based on the sitting duration being greater than or equal to a first set duration, determining the target flush mode to be a large flush mode;

[0059] Based on the sitting duration being greater than or equal to a second set duration and less than the first set duration, and the hip washing function being operated during the sitting period, determining the target flush mode to be the large flush mode; the second set duration is less than the first set duration;

[0060] Based on the sitting duration being greater than or equal to the second set duration and less than the first set duration, and the hip washing function not being operated during the sitting period, determining the target flush mode to be a small flush mode.

[0061] The sitting duration can be detected by a timer in the system. The timer starts when the first sitting signal is detected, and ends when the last standing signal is detected. The duration between the first sitting signal and the last standing signal is the sitting duration. The sitting signal and the standing signal can be detected by a sensor (e.g. pressure sensor) on the toilet seat. When the pressure sensor detects an increase in pressure, it detects a sitting signal. When the pressure sensor detects a decrease in pressure, it detects a standing signal. Since the user can move position during the toilet process, which can cause the standing signal and the sitting signal to be detected in succession during the toilet process, but the time is very short, so it is not a real standing, it is still accumulated as the sitting duration, and no flushing. Therefore, only when a standing signal is detected and a period of time (e.g. greater than or equal to the set standing duration) has passed without detecting a sitting signal again, it is proved that the user is a real standing, and the standing signal is the last standing signal. The timer can be segmented and sent to the processor, i.e. the timer starts again each time a sitting signal / standing signal is detected, until a standing signal is detected after a certain time and no sitting signal is detected again, then the standing signal is the last standing signal. The processor can determine the last standing signal accordingly, and then add each segment of the duration between the first sitting signal and the last standing signal to obtain the sitting duration.

[0062] The opening and closing of the hip washing function will generate corresponding electrical signals in the system. Therefore, whether the hip washing function is running can be determined by whether the corresponding electrical signal is generated. For example, if the user presses the hip washing button during the sitting process, it indicates that the hip washing function is running during the sitting period.

[0063] When the sitting duration is greater than or equal to the first set duration, it indicates that the user is sitting to use the toilet and the toilet time is relatively long, which is usually a defecation scenario, so the target sewage flushing mode can be determined as the large flushing mode.

[0064] When the sitting duration is greater than or equal to the second set duration and less than the first set duration, and the hip washing function is running during the sitting period, it indicates that the user is sitting to use the toilet for a period of time, although the duration is not long, but the hip washing function is used, which is usually a defecation scenario, so the target sewage flushing mode can be determined as the large flushing mode.

[0065] When the sitting duration is greater than or equal to the second set duration and less than the first set duration, and the hip washing function is not running during the sitting period, it indicates that the user is sitting to use the toilet for a period of time, but the duration is not long, and the hip washing function is not used, which is usually a female urination scenario, so the target sewage flushing mode can be determined as the small flushing mode.

[0066] When the sitting duration is less than the second set duration, it indicates that the user's sitting duration is very short, which may be a mistake of pressing the toilet seat, and it is not a real toilet, so it does not enter the sewage flushing mode and does not flush.

[0067] The first set time length can be, but is not limited to, in the range of 20s to 1min; the second set time length can be, but is not limited to, in the range of 1s to 6s; and the set away time length can be, but is not limited to, in the range of 5s to 15s.

[0068] In some example embodiments, the internal detection information includes lid-closing flushing association information; and the target flushing mode is automatically determined according to the internal detection information, including: determining the target flushing mode according to the lid-closing flushing association information. This scheme can be applied to a toilet without an automatic lid-closing function or with an automatic lid-closing function that cannot be selected to be opened or closed.

[0069] The internal detection information includes an opening and closing state of an automatic lid-closing function and lid-closing flushing association information; and the target flushing mode is automatically determined according to the internal detection information, including: based on the automatic lid-closing function being in an open state, determining the target flushing mode according to the lid-closing flushing association information. This scheme can be applied to a toilet with a selectable automatic lid-closing function.

[0070] Some toilets also have an automatic lid-closing function that can be opened and closed according to user needs. When this function is closed, the toilet does not automatically close the lid, and the target flushing mode can be determined according to the away flushing association information. When the function is open, the toilet will automatically close the lid, and the target flushing mode can be determined according to the lid-closing flushing association information, which is conducive to reducing the flushing noise.

[0071] For toilets without an automatic lid-closing function or with an automatic lid-closing function that cannot be closed, the target flushing mode can also be determined according to the lid-closing flushing association information, which is conducive to reducing the flushing noise.

[0072] In some example embodiments, the lid-closing flushing association information includes a sitting time length, whether the hip washing function is operated during the sitting period, and whether the cover is closed; and the target flushing mode is determined according to the lid-closing flushing association information, including:

[0073] Based on the cover being closed after the sitting time length being greater than or equal to a third set time length, the target flushing mode is determined to be a large flushing mode;

[0074] Based on the cover being closed after the sitting time length being greater than or equal to a fourth set time length and less than the third set time length, and the hip washing function being operated during the sitting period, the target flushing mode is determined to be a large flushing mode, and the fourth set time length is less than the third set time length;

[0075] Based on the cover being closed after the sitting time length being greater than or equal to the fourth set time length and less than the third set time length, and the hip washing function not being operated during the sitting period, the target flushing mode is determined to be a small flushing mode.

[0076] The seat-on signal, the seat-off signal, the seat-on duration, and the detection of whether the hip washing function is operated during the seat-on period can refer to the foregoing solutions, which will not be described here again.

[0077] Whether the cover is closed can be detected by a detection element for detecting the state of the toilet cover. For a toilet with an automatic cover closing function, the state of the toilet cover matches the position of the mechanical driving mechanism for driving the rotation of the toilet cover, so the state of the toilet cover can be determined by detecting the position of some components (such as the motor shaft, hinge shaft, etc.) of the mechanical driving mechanism. Alternatively, regardless of whether the toilet has an automatic cover closing function, light sensors can be arranged on both sides of the toilet seat, and when the cover is closed, the light emitted by the light sensor is blocked, generating a cover closing signal; when the cover is opened, the light emitted by the light sensor is not blocked, generating a cover opening signal.

[0078] When the seat-on duration is greater than or equal to the third set duration and the cover is closed, it indicates that the user sits down to defecate and the defecation time is relatively long, which is usually a defecation scenario, so the target flushing mode can be determined as the large flushing mode.

[0079] When the seat-on duration is greater than or equal to the fourth set duration and less than the third set duration, the cover is closed, and the hip washing function is operated during the seat-on period, it indicates that the user sits down to defecate for a period of time, although the duration is not long, but the hip washing function is used, which is usually a defecation scenario, so the target flushing mode can be determined as the large flushing mode.

[0080] When the seat-on duration is greater than or equal to the fourth set duration and less than the third set duration, the cover is closed, and the hip washing function is not operated during the seat-on period, it indicates that the user sits down to defecate for a period of time, although the duration is not long, but the hip washing function is not used, which is usually a female urination scenario, so the target flushing mode can be determined as the small flushing mode.

[0081] The cover can be arranged to be closed when the seat-off duration reaches a set seat-off duration. The third set duration can be in, but not limited to, the range of 20s to 1min; the fourth set duration can be in, but not limited to, the range of 1s to 6s; and the set seat-off duration can be in, but not limited to, the range of 5s to 15s.

[0082] In some exemplary embodiments, the target flushing mode is automatically determined according to the internal detection information, comprising:

[0083] Based on the determination that the male urination is ended according to the internal detection information, the target flushing mode is determined as the small flushing mode.

[0084] In some exemplary embodiments, the internal detection information comprises a seat opening signal, an external liquid inflow signal, and an external liquid inflow end signal.

[0085] Determining the end of the male urination according to the internal detection information, comprising: determining the end of the male urination based on the detection of the seat opening signal, the external liquid inflow signal and the external liquid inflow end signal in sequence.

[0086] When the seat opening signal, the external liquid inflow signal and the external liquid inflow end signal are detected in sequence, it can be indicated that it is male urination and the urination is over.

[0087] The seat opening signal can be detected according to the seat sensor. For example, the seat bottom surface is provided with a light sensor, and when the seat is opened, the light emitted by the light sensor is not blocked, generating a seat opening signal; when the seat cover is closed, the light emitted by the light sensor is blocked, generating a seat cover closing signal. The external liquid inflow signal and the external liquid inflow end signal can be detected according to the microwave sensor arranged on the bottom surface of the toilet seat. The microwave sensor can detect moving urine and also can detect human bodies. When moving urine is detected, the external liquid inflow signal is detected; when moving urine disappears, the external liquid inflow end signal is detected.

[0088] In some exemplary embodiments, the brush ring flushing device 2 and the driving device are controlled according to the target sewage flushing mode, comprising:

[0089] Based on the target sewage flushing mode being a large flushing mode, the brush ring flushing device 2 and the driving device are controlled to act, so that the toilet enters a large flushing sewage process;

[0090] Based on the target sewage flushing mode being a small flushing mode, the brush ring flushing device 2 and the driving device are controlled to act, so that the toilet enters a small flushing sewage process.

[0091] The brush ring flushing device 2 is continuously turned on in the large flushing sewage process and the small flushing sewage process. The large flushing sewage process and the small flushing sewage process both include: a turning sewage stage, a maintaining sewage stage, a turning reset stage and a water seal supplement stage. In the turning sewage stage, the driving device drives the sewage pipe 3 to rotate from the water supplement position to the sewage position. In the maintaining sewage stage, the driving device stops moving, so that the sewage pipe 3 is maintained at the sewage position. In the turning reset stage, the driving device drives the sewage pipe 3 to reset from the sewage position to the water supplement position. In the water seal supplement stage, the driving device stops moving, so that the sewage pipe 3 is maintained at the water supplement position.

[0092] In the turning sewage stage, the sewage in the toilet can flow downward and be discharged under the action of gravity and the inertia of falling. In the maintaining sewage stage, the sewage continues to flow downward under the action of water flow, which is beneficial to the complete discharge of the sewage. In the turning reset stage, the sewage pipe 3 can be reset to the water supplement position under the driving of the driving device. In the water seal supplement stage, the driving device stops moving, and the brush ring flushing device 2 continues to discharge water, which can ensure that a water seal is formed in the toilet.

[0093] The duration of the turning phase is recorded as A seconds, which can be in the range of but not limited to 0.2s to 1.5s. The duration of the holding phase is recorded as B seconds (corresponding to the large flush mode) / E seconds (corresponding to the small flush mode), B seconds can be in the range of but not limited to 1.5s to 4.5s, and E seconds can be in the range of but not limited to 0.5s to 3s. The duration of the turning reset phase is recorded as C seconds, which can be in the range of but not limited to 0.3s to 1.5s. The duration of the water seal supplement phase is recorded as D seconds, which needs to be determined according to the size of the pot surface 11.

[0094] Among them, the duration of the holding phase of the large flush process is longer than that of the small flush process, which is beneficial to ensure the effect of the large flush mode and save water in the small flush mode.

[0095] In some exemplary embodiments, the determining factors of the target flushing mode include the amount of water used for flushing. The target flushing mode determined according to the amount of water used for flushing includes the water-saving flushing mode and the conventional flushing mode.

[0096] According to the target flushing mode, the control of the brush circle flushing device 2 and the driving device includes:

[0097] Based on the target flushing mode being the water-saving flushing mode, the brush circle flushing device 2 and the driving device are controlled to start at the same time, so that the closestool directly enters the flushing process;

[0098] Based on the target flushing mode being the conventional flushing mode, the brush circle flushing device 2 is controlled to start first, and the driving device is controlled to start later, so that the closestool enters the pot surface cleaning process first and then enters the flushing process.

[0099] In the water-saving flushing mode, there is no separate pot surface cleaning process, which is equivalent to the pot surface cleaning process and the flushing process being carried out at the same time, which is beneficial to shorten the water discharge duration of the brush circle flushing device 2 and save water.

[0100] In the conventional flushing mode, the pot surface cleaning process and the flushing process are carried out separately, and the separate pot surface cleaning process can first clean the pot surface 11, which is beneficial to the falling of the dirt on the pot surface 11, thereby improving the flushing effect.

[0101] As for the determination method of the water-saving flushing mode and the conventional flushing mode, it can also be determined according to the externally input instruction information, such as the user sending instructions through a remote control, voice, APP, etc.; it can also be automatically determined according to internal detection information, such as automatically obtaining the last setting and automatically using the last selected mode.

[0102] In some exemplary embodiments, the determining factor of the target flushing mode further includes a pollution scenario. The water-saving flushing mode determined according to the pollution scenario includes a water-saving small flushing mode and a water-saving large flushing mode. The conventional flushing mode determined according to the pollution scenario includes a conventional small flushing mode and a conventional large flushing mode.

[0103] In the water-saving small flushing mode and the conventional small flushing mode, the pollution process is a small flushing pollution process. The specific content of the small flushing pollution process can refer to the small flushing pollution process in the foregoing scheme, and will not be described here again.

[0104] In the water-saving large flushing mode and the conventional large flushing mode, the pollution process is a large flushing pollution process. The specific content of the large flushing pollution process can refer to the large flushing pollution process in the foregoing scheme, and will not be described here again.

[0105] The duration of the pot surface cleaning process in the conventional large flushing mode is greater than the duration of the pot surface cleaning process in the conventional small flushing mode. This is conducive to ensuring the pollution effect of the large flushing mode and saving water in the small flushing mode.

[0106] The duration of the pot surface cleaning process is F seconds (corresponding to the large flushing mode) / G seconds (corresponding to the small flushing mode). F seconds can be in the range of 1.5s to 6s, and G seconds can be in the range of 1s to 4s.

[0107] In one embodiment, as shown in FIG. 6, the water-saving flushing mode includes the following steps: Figure 5

[0108] Receiving a flushing signal;

[0109] Opening the waterway switch valve 21, the brush ring is water-washed to clean the pot surface 11; the gear box assembly 4 drives the pollution pipe 3 to overturn for A seconds to reach the pollution position;

[0110] The waterway switch valve 21 is continuously opened, the water is washed to clean the pot surface 11 and flush the dirt; the pollution pipe 3 remains in the pollution position for B seconds / E seconds;

[0111] The waterway switch valve 21 is continuously opened, the water is supplied to the ceramic pot surface 11, the gear box assembly 4 drives the pollution pipe 3 to overturn for C seconds to reset to the water supply position;

[0112] The waterway switch valve 21 is continuously opened, the water is supplied to the ceramic pot surface 11 to complete the water seal state, and the pollution pipe 3 remains in the reset state, and the process lasts for D seconds.

[0113] In the water-saving flushing mode, the pollution pipe 3 overturns and flushes synchronously with the brush ring water-washed, and the large flushing mode and the small flushing mode are distinguished by controlling the duration of maintaining the pollution position (B>E). Figure 6

[0114] As shown in FIG. 6.​​​​​​​​​​​​​​​​​​​​​​​​​​​​Figure 7 As shown, the conventional flushing mode includes the following steps:

[0115] The flushing signal is received;

[0116] The waterway on-off valve 21 is opened, and the brush circle is filled with water to wash the pot surface 11 for F seconds / G seconds;

[0117] The waterway on-off valve 21 is continuously opened, and the brush circle is filled with water to wash the pot surface 11; the gear box assembly 4 drives the drain pipe 3 to overturn for A seconds to reach the drain position;

[0118] The waterway on-off valve 21 is continuously opened, and the brush circle is filled with water to wash the pot surface 11 and flush the dirt; the drain pipe 3 remains in the drain position for B seconds / E seconds;

[0119] The waterway on-off valve 21 is continuously opened, and the brush circle is filled with water to wash the pot surface 11 and flush the dirt; the drain pipe 3 remains in the drain position for B seconds / E seconds;

[0120] The waterway on-off valve 21 is continuously opened, and the brush circle is filled with water to wash the pot surface 11 and flush the dirt; the drain pipe 3 remains in the drain position for B seconds / E seconds;

[0121] In the conventional flushing mode, the brush circle is first filled with water to wash the pot surface 11, and then the drain pipe 3 is overturned to drain. By controlling the time length of washing the pot surface 11 by the brush circle (F>G) and the time length of maintaining the drain position (B>E), the large flushing mode and the small flushing mode can be distinguished, as shown in the following table.
