Therefore, the present disclosure should not be interpreted as being limited to the content described in the following embodiments. The embodiments in the present disclosure and the features in the embodiments can be combined with each other at will without conflict. In order to keep the following description of the embodiments of the present disclosure clear and brief, the present disclosure omits the detailed description of some known functions and known components. The drawings of the embodiments of the present disclosure only involve the structures related to the embodiments of the present disclosure, and other structures can be referred to the general design.

[0027] The ordinal numbers "first", "second", "third" and the like in the present specification are set in order to avoid confusion of the components, and are not intended to be limiting in terms of number.

[0028] In the present specification, for the convenience, the words indicating the orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are used to describe the positional relationship of the components with reference to the drawings, and are only for the convenience of describing the present specification and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure. The positional relationship of the components is appropriately changed according to the direction of describing each component. Therefore, it is not limited to the words described in the specification, and can be appropriately changed according to the situation.

[0029] Figures 1 to 5 For the example of the intelligent toilet of the embodiments of the present disclosure, it includes a toilet body 1, a flushing device, a turnover sewage unit and a sewer pipe assembly.

[0030] The toilet body 1 is provided with a bowl cavity, and a part of the inner wall surface of the bowl cavity is a pot surface. The space surrounded by the pot surface is used to store water to form a water seal. The bottom of the pot surface is provided with a sewage outlet, which is communicated with the turnover sewage unit.

[0031] The flushing device includes a brush circle water inlet nozzle 2 and an on-off valve 5, and the on-off valve 5 is provided with a flow detection device, which can be a flow meter. The on-off valve 5 controls the water inlet of the pot surface by opening and closing, so as to realize the processes of brushing the ceramic pot surface, discharging sewage and water seal replenishment.

[0032] The tilting sewage discharge unit may include a sewage box 3, a sewage pipe 4, and a drive device. The sewage pipe 4 is rotatably connected to the sewage discharge channel and is operably rotatable; the sewage pipe 4 is at least partially located within the sewage box 3. The drive device is connected to the sewage pipe 4 and configured to drive the sewage pipe 4 to rotate relative to the toilet body 1 between a standby position, a water-deficient position, and a sewage discharge position. When the sewage pipe 4 is in the standby position, the sewage outlet 8 faces upward (it can be horizontally upward or tilted upward), and a water seal is formed on the toilet body. When the sewage pipe 4 is in the sewage discharge position, the sewage outlet 8 faces downward (it can be horizontally downward or tilted downward), and waste is discharged. When the sewage pipe 4 is in the water-deficient position, the lowest point of the sewage outlet is lower than the standby position but higher than the sewage discharge position. Figure 3 The image shows drain pipe 4 in its standby position. Figure 4 The image shows sewage pipe 4, which is located in a water-scarce area. Figure 5 The image shows sewage pipe 4, which is located at the sewage discharge point.

[0033] The distance L1 between the drain outlet 8 and the inner wall of the drain box 4 in the water-deficient location (e.g.) Figure 4 (As shown) is greater than the distance L2 from the inner wall of the drain box in the standby position (e.g.) Figure 3 (As shown). Since the distance L1 between the drain outlet and the inner wall of the drain box in the water-deficient position is greater than the distance L2 between the drain outlet and the inner wall of the drain box in the standby position, the drainage space formed between the drain outlet and the drain box in the water-deficient position is greater than the drainage space formed between the drain pipe and the drain box in the standby position. This allows users to flush waste to the external drain pipe with less water. When the drain pipe is in the drainage position, the drain outlet is at least partially facing the waste outlet 9 below the drain box.

[0034] 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. The gearbox assembly is connected to the drain pipe 4 and can drive the drain pipe 4 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 4 can rotate in both directions.

[0035] The drainage pipe assembly includes a shifter assembly 7. The shifter assembly 7 is connected to the outlet of the drain box 3 and the external drain pipe.

[0036] The control unit 6 is electrically connected to the tilting sewage discharge unit to control the drive device and the switching valve 5.

[0037] For example, control unit 6 includes a memory and a processor. The memory is used to store the first program; The processor is used to read and execute the first program to perform the sewage control method described in any embodiment.

[0038] The toilet adopts a turnover sewage discharge mode, and sewage in the toilet is discharged out of the toilet pot surface and the toilet pipeline by means of natural gravity falling. During the sewage discharge process, the sewage discharge pipe 4 rotates around the rotation axis to perform dumping sewage discharge, and the sewage in the toilet pot surface is efficiently and quickly discharged out through the sewage discharge pipe 4 under the action of gravity and falling inertia.

[0039] The conventional sewage discharge action of the sewage discharge pipe can include a turnover sewage discharge phase, a sewage discharge maintaining phase, a turnover reset phase and a water seal supplement phase; in the turnover sewage discharge phase, the driving device drives the sewage discharge pipe to rotate from the standby position to the sewage discharge position; in the sewage discharge maintaining phase, the driving device stops moving; in the turnover reset phase, the driving device drives the sewage discharge pipe to reset from the sewage discharge position to the standby position; and in the water seal supplement phase, the driving device stops moving.

[0040] The time length of each phase in the sewage discharge process can be set as required. In the water seal supplement phase, a volume can be set, and the volume can be determined according to the water inflow and the water inflow time length of the water seal supplement phase. After the set volume is reached or the water inflow time length of the water seal supplement phase is reached, the hot water valve is controlled to be closed.

[0041] Figure 6 As one of the sewage discharge control methods of the embodiments of the present disclosure, the sewage discharge control method is applied to the intelligent toilet described above, and includes: Step 11, in response to a flushing instruction, obtaining a water inflow; Step 12, when feedback information of the water inflow does not conform to predetermined specified information, controlling the sewage discharge pipe to rotate downward from the standby position to the water deficiency position.

[0042] The sewage discharge control method of the embodiments of the present disclosure controls the sewage discharge pipe to rotate downward from the standby position to the water deficiency position when the feedback information of the water inflow does not conform to the predetermined specified information, so that water seal deficiency is not caused, and thus problems of bathroom counter-odor or pest invasion caused by water seal deficiency or being too low are avoided.

[0043] In an exemplary embodiment, the flushing instruction can include various flushing operations triggered by the user through a button, a knob, a remote control or induction. For example, the user triggers the flushing instruction by pressing or short-pressing a side button or a knob. For another example, the user triggers the flushing instruction by short-pressing a “flushing” key or long-pressing a “flushing” key of a remote controller. For another example, the system automatically issues the flushing instruction when the user sits down for more than or equal to 10 seconds and gets up for more than or equal to 5 seconds.

[0044] Exemplarily, after the blowdown pipe is rotated to the water shortage position, the blowdown pipe can be controlled to rotate from the water shortage position to the standby position for water replenishment when the feedback information of the water inflow flow rate conforms to the predetermined specified information; or the blowdown pipe can be controlled to rotate from the water shortage position to the blowdown position for blowdown operation when the feedback information of the water inflow flow rate conforms to the predetermined specified information, and the blowdown pipe is controlled to rotate from the blowdown position to the standby position for water seal replenishment after the blowdown is completed; or the blowdown pipe can be controlled to rotate from the water shortage position to the standby position for water replenishment when the feedback information of the water inflow flow rate conforms to the predetermined specified information, and the blowdown pipe is controlled to rotate from the standby position to the blowdown position for blowdown operation after the water replenishment is completed, and the blowdown pipe is controlled to rotate from the blowdown position to the standby position for water seal replenishment after the blowdown is completed.

[0045] In an exemplary embodiment, the feedback information comprises a size relationship between the water inflow flow rate and a threshold value and / or whether the flow rate detection device is invalid.

[0046] For example, the feedback information comprises that the water inflow flow rate is less than the threshold value. Exemplarily, the threshold value can be 3 liters / minute.

[0047] Exemplarily, the predetermined specified information comprises that the water inflow flow rate is greater than or equal to the threshold value and the flow rate detection device is valid.

[0048] Exemplarily, the flow rate detection device can be a flow meter arranged at the on-off valve.

[0049] Exemplarily, the on-off valve is an electromagnetic on-off valve based on the Hall effect. The water inflow flow rate can be sampled at a sampling frequency of 1 Hz, and real-time data interaction is performed with the control unit 6 through a high-speed serial communication interface.

[0050] Figure 7 For the second blowdown control method of the embodiments of the present disclosure, the blowdown control method is applied to the intelligent toilet described above, comprising: Step 21, in response to a flushing instruction, obtaining a water inflow flow rate; Step 22, when feedback information of the water inflow flow rate does not conform to predetermined specified information, controlling the blowdown pipe to rotate downward from the standby position to the water shortage position; Step 23, obtaining a water inflow flow rate, when feedback information of the water inflow flow rate conforms to predetermined specified information, controlling the blowdown pipe to rotate from the water shortage position to the blowdown position, and controlling the blowdown pipe to rotate from the blowdown position to the standby position for water seal replenishment after blowdown.

[0051] The present embodiment is different from the first blowdown control method of the embodiments of the present disclosure in that Figure 6The difference in the sewage control method shown is the addition of step 23, which allows for the detection of influent flow rate and determination of the relationship between influent flow rate and threshold, as well as the effectiveness of flow detection device, after water shortage. When influent flow rate is greater than or equal to threshold and flow detection device is effective, the sewage pipe is controlled to rotate to the sewage discharge position for sewage discharge, thus enabling sewage discharge after water supply.

[0052] Step 23 can also be replaced by: obtaining the inlet water flow rate; when the feedback information of the inlet water flow rate meets the predetermined information, controlling the drain pipe to rotate from the water shortage position to the standby position and replenishing water; and performing the normal draining operation after the water replenishment is completed.

[0053] The replaced step 23 can replenish water after the water comes in, thereby making up for the water lost when the sewage pipe changes from the standby position to the water shortage position, so that the amount of water used for sewage discharge reaches the normal sewage discharge volume.

[0054] Figure 8 This is a third sewage control method according to an embodiment of the present disclosure. This sewage control method is applied to the aforementioned smart toilet and includes: Step 31: In response to the flushing command, obtain the inlet water flow rate; Step 32: When the feedback information of the inlet water flow does not meet the predetermined information, control the drain pipe to rotate downward from the standby position to the water shortage position; Step 33: Periodically turn on the flushing device and check the inlet water flow rate; Step 34: Obtain the inlet water flow rate. When the feedback information of the inlet water flow rate meets the predetermined information, control the drain pipe to rotate from the water shortage position to the drain position, and after draining, control the drain pipe to rotate from the drain position to the standby position to replenish the water seal.

[0055] This embodiment and Figure 6 The difference in the sewage control method shown is the addition of steps 33 and 34. After water shortage, the influent flow rate can be periodically detected to determine the relationship between the influent flow rate and the threshold, as well as the effectiveness of the flow detection device. When the influent flow rate is greater than or equal to the threshold and the flow detection device is effective, the sewage pipe is controlled to rotate to the sewage discharge position for sewage discharge, so that sewage can be discharged as soon as water is available.

[0056] Figure 9 This is a fourth sewage control method according to an embodiment of the present disclosure. This sewage control method is applied to the aforementioned smart toilet and includes: Step 41: In response to the flushing command, obtain the inlet water flow rate; Step 42: When the feedback information of the inlet water flow rate meets the predetermined information, control the drain pipe to rotate downward from the standby position to the drain position.

[0057] The embodiment and Figure 6 The sewage control method shown in the difference is step 42, so that the normal sewage operation is performed when the water inflow is greater than or equal to the threshold value and the flow monitoring device is effective.

[0058] Figure 10 For the fifth sewage control method of the present disclosure, the sewage control method is applied to the intelligent toilet described above, comprising: Step 51, obtaining the water inflow; Step 52, when the feedback information of the water inflow conforms to the predetermined specified information, the control mode is switched to the first control mode; when the feedback information of the water inflow does not conform to the predetermined specified information, the control mode is switched to the second control mode.

[0059] The first control mode comprises: in response to the flushing instruction, controlling the sewage pipe to rotate downward from the standby position to the sewage position; The second control mode comprises: in response to the flushing instruction, controlling the sewage pipe to rotate downward from the standby position to the water shortage position.

[0060] The embodiment and Figure 6 The difference between the sewage control method shown in the embodiment and

[0061] Figure 11 For the sixth sewage control method of the present disclosure, the sewage control method is applied to the intelligent toilet described above, comprising: Step 61, in response to the flushing instruction, obtaining the current control mode of the control unit; Step 62, when the control mode is the normal control mode, controlling the sewage pipe to rotate downward from the standby position to the sewage position; when the control mode is the water shortage mode, controlling the sewage pipe to rotate downward from the standby position to the water shortage position.

[0062] The embodiment and Figure 10 The difference between the sewage control method shown in the embodiment and Figure 10 The sewage control method shown in the embodiment performs control mode switching when obtaining the water inflow, and does not need to obtain the control mode when receiving the flushing instruction; and Figure 11 The sewage control method shown in the embodiment obtains the current control mode in response to the flushing instruction.

[0063] Figure 12 For the seventh sewage control method of the present disclosure, the sewage control method is applied to the intelligent toilet described above, comprising: Step 71, obtaining the water inflow, and determining whether the intelligent toilet is out of water and / or the flow detection device is invalid based on the water inflow; Step 72, when it is determined that the intelligent toilet is not out of water and / or the flow detection device is valid, determining that the current control mode is a normal control mode; when it is determined that the intelligent toilet is out of water and / or the flow detection device is invalid, determining that the current control mode is an out-of-water mode; Step 73, obtaining the current control mode of the control unit in response to a flushing instruction; Step 74, when the control mode is the normal control mode, controlling the sewage pipe to rotate downward from the standby position to the sewage position; when the control mode is the out-of-water mode, controlling the sewage pipe to rotate downward from the standby position to the out-of-water position.

[0064] Compared with the sewage control method shown in Figure 11 the sewage control method of the embodiment of the present disclosure specifically limits the conditions under which the control mode is determined and how the control mode is determined.

[0065] Figure 13 For the eighth sewage control method of the embodiment of the present disclosure, the sewage control method is applied to the intelligent toilet described above, comprising: Step 81, obtaining the current position of the sewage pipe in response to a flushing instruction; Step 82, when the sewage pipe is located at the out-of-water position, issuing an out-of-water indication to the user.

[0066] The embodiment is different from the above-mentioned embodiments in that it can alarm when out of water, so that the user knows that the toilet is out of water.

[0067] In an exemplary embodiment, the toilet further comprises an alarm device.

[0068] Exemplarily, the alarm device comprises at least one of a sounder and an indicator light; The alarm signal comprises at least one of a sound alarm signal or a light alarm signal.

[0069] Exemplarily, the user is prompted that the toilet is out of water, for example, through the sounder.
