Description

Technical Field

[0001] The present invention belongs to the technical field of smart home appliances, and in particular relates to an abnormal response method based on a washing pump and a washing device. Background Art

[0002] With the continuous development of intelligence and automation, smart home appliances have gradually entered thousands of households, providing users with a variety of services. When washing dishes, existing washing machines can use a washing pump to deliver water at a certain water pressure into the washing chamber to clean and rinse the surface of the dishes to remove stains on the tableware in order to ensure a good cleaning effect. Therefore, to ensure that the water pressure in the washing chamber reaches the rated water pressure threshold, the water supply line of the washing machine is often equipped with a corresponding water pressure switch. When the water pressure switch is closed, it indicates that the current water pressure meets the cleaning requirements, thus achieving precise control of the washing machine.

[0003] With the existing control technology for smart home appliances, when the washing machine starts the washing pump and encounters water supply abnormalities, it is impossible to determine whether the abnormal water supply is caused by a water channel blockage or insufficient water pressure. As a result, it is impossible to respond according to the specific abnormality, which greatly reduces the robustness of the washing machine and increases the probability of failure to perform the washing operation normally. Summary of the Invention

After the washing pump is turned on, if there is an abnormality in water delivery, it is impossible to determine whether the abnormal water delivery is caused by water channel blockage or insufficient water pressure. Therefore, it is impossible to respond according to the specific abnormality, which greatly reduces the robustness of the washing equipment and increases the probability of failure to perform the washing operation normally.

[0047] In an embodiment of the present invention, a detection circuit is connected in series with a circuit of a water pressure switch located in the water supply line of a washing pump. The detection circuit detects the open / close state of the water pressure switch after the washing pump is started. When the water pressure in the water supply line reaches a preset water pressure threshold, the water pressure switch closes, thereby placing the circuit containing the detection circuit in a connected state. When the water pressure does not reach the preset water pressure threshold, the water pressure switch opens, and the circuit containing the detection circuit also opens. Therefore, when the washing machine detects that the detection circuit is in the open state, it can identify that the water pressure in the current water line is insufficient and execute an abnormal response operation of the washing pump, thereby automatically correcting the insufficient water pressure. Compared with existing smart appliance control technologies, this embodiment can distinguish whether the abnormality in water supply is caused by insufficient water pressure or a water line blockage. When the abnormality is determined to be caused by insufficient water pressure, the corresponding abnormal response operation can be executed to correct the abnormality, thereby improving the robustness of the washing machine and reducing the probability of the washing machine not functioning properly due to the abnormality.

[0058] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0059] The embodiment of the present invention connects a detection circuit in series within the circuit of the water pressure switch deployed on the water supply waterway of the washing pump, and obtains the opening and closing status of the water pressure switch after the washing pump is started through the detection circuit. When the water pressure in the water supply waterway reaches a preset water pressure threshold, the water pressure switch will be closed, so that the loop where the detection circuit is located will be in a connected state. When the water pressure does not reach the preset water pressure threshold, the water pressure switch will be disconnected, and then the loop where the detection circuit is located will also be in a disconnected state. Therefore, when the washing device detects that the detection circuit is in a disconnected state, it can identify that the water pressure in the current waterway is insufficient, and therefore it will execute the abnormal response operation of the washing pump, thereby automatically repairing the insufficient water pressure situation, solving the problem that the control technology of smart home appliances cannot determine whether the water supply abnormality is caused by waterway blockage or the water supply abnormality is caused by insufficient water pressure, and thus cannot respond according to the specific abnormality, thereby greatly reducing the robustness of the washing device and increasing the probability of failure to perform the washing operation normally.

[0060] In an embodiment of the present invention, the execution subject of the process is a washing device, which includes but is not limited to: a dishwasher, a bottle washer and other equipment with a washing function, wherein the washing device includes a washing pump, through which water is transported to the washing chamber to complete the cleaning task. It should be noted that a water pressure switch is configured on the water channel in which the washing pump transports water. When the water pressure in the water channel reaches a preset water pressure threshold, the corresponding water channel will be connected to ensure that the water pressure during washing can meet the washing requirements. For example, Figure 1 The schematic diagram of the structure of the water supply channel provided by an embodiment of the present application is shown. Figure 1As shown, the water supply circuit of this washing machine specifically includes three components: a washing pump 11 that delivers water at a specified pressure into the washing chamber, a water pressure switch 12 for detecting the water pressure in the water supply circuit, and a detection circuit 13 for determining the closed state of the water pressure switch. The water pressure switch 12 can move according to the actual water pressure in the water supply circuit. When the water pressure reaches a preset threshold, the water pressure switch moves to the target position, connecting the water circuit and allowing water to be delivered to the washing chamber through the water outlet to complete the washing task.

[0061] Figure 2 The following is a flowchart illustrating an implementation of an abnormal response method based on a washing pump according to a first embodiment of the present invention, which is described in detail as follows:

[0062] In S201 , in response to a start instruction of the washing pump, the washing pump is turned on.

[0063] In this embodiment, when the washing machine starts the washing pump, it can generate a start-up instruction for the washing pump. The washing machine can store the operation process of this washing operation, and when switching to different operation stages, it generates corresponding operation instructions, which are used to start the relevant components to perform the operations associated with the stage. For example, in the water inlet stage, the washing machine can generate multiple instructions related to water inlet, such as the valve opening instruction of the water inlet valve and the start-up instruction of the washing pump, and transmit the above instructions to the relevant components and modules in the washing machine. After receiving the corresponding instructions, each component and module can perform the corresponding action. For example, after the washing pump receives the start-up instruction, it can run the motor in the washing pump to pump water from the water inlet waterway through the motor to transport it to the washing chamber of the washing machine, so as to achieve the operation of rinsing the dishes to be washed in the washing chamber.

[0064] In one possible implementation, the washing device can determine multiple water supply trigger moments based on the operating process corresponding to the current washing operation, and generate a start instruction for the above-mentioned washing pump when it detects that the current operating time reaches any preset water supply trigger moment. After the washing device detects the above-mentioned start instruction, it executes the operation S201.

[0065] In S202, the on-off state of the detection circuit is obtained, and the detection circuit is used to determine whether the water pressure switch located on the water supply waterway of the washing pump has reached the target position; the water pressure switch will reach the target position when the water pressure in the water supply waterway reaches a preset water pressure threshold.

[0066] In this embodiment, after the washing pump is turned on, the washing equipment can obtain the on-off state of the detection circuit. Figure 1It can be determined from the structural diagram that when the water pressure of the washing pump meets the rated water pressure threshold, the water pressure switch will move to the target position. When the water pressure switch is in the target position, it will be connected to the water channel corresponding to the water outlet to ensure that the water flow can be delivered to the washing chamber through the water outlet. At the same time, when the water pressure switch moves to the target position, the electrical circuit where the detection circuit is located is connected. At this time, the detection circuit will be in a connected state; when the water pressure switch does not reach the target position, it means that the water pressure of the delivery water channel is less than the preset water pressure threshold. At this time, not only can the water channel between the water outlet be connected, but the circuit where the detection circuit is located is also in a disconnected state. Therefore, the on-off state of the detection circuit can be identified to determine whether the water pressure of the delivery water channel meets the preset requirements.

[0067] In the prior art, without a corresponding detection circuit, if the water supply channel fails to discharge water normally, it is impossible to determine whether the failure is due to a blockage in the channel or a disconnection of the water channel due to insufficient water pressure from the washing pump, making it impossible to identify the abnormal situation. In this embodiment, a detection circuit connected in series with the water pressure switch is configured in the same circuit. This circuit can detect whether the water pressure in the water supply channel has reached a preset target position and whether the water pressure has reached a threshold. This detection circuit can also be associated with the on / off state of the water pressure switch. The washing machine can identify the status of the water pressure switch by identifying the connectivity of the detection circuit.

[0068] In one possible embodiment, a water outlet detection component may be provided in the washing chamber of the washing device to determine whether the water outlet can discharge water normally. If it is detected that the water outlet can discharge water normally, it indicates that there is no abnormality in the water supply circuit. At this time, there is no need to perform S202 and S203 operations, but the washing operation can be continued. On the contrary, if the water outlet detection component detects that the water outlet is in an abnormal water outlet state, such as the flow value of the flow meter is less than the preset threshold value, it is identified that the water supply circuit is in an abnormal state, and the step S202 is performed to identify the abnormal situation. If the on-off state of the detection circuit is detected to be connected, it is identified that the water outlet circuit is in a blocked state. At this time, an abnormal prompt message of water channel blockage can be generated to prompt the user to repair the abnormal water outlet.

[0069] In S203, if the on-off state is the off state, an abnormal response operation on the washing pump is performed.

[0070] In this embodiment, if the detection circuit remains disconnected after the washing pump is turned on, it indicates that the water pressure switch has not reached the target position. In this case, it indicates that there is an abnormality in the washing pump, resulting in the water pressure in the water supply circuit not reaching the required level (i.e., reaching the water pressure threshold). This situation may be caused by insufficient power of the washing pump or excess gas in the washing pump, which affects the pressure increase. Therefore, to adjust for this situation, the washing machine can perform an abnormal response operation for the washing pump to increase the water pressure in the water supply circuit to meet the water supply requirements.

[0071] In one possible implementation, the above-mentioned abnormal response operation may be: increasing the operating power of the washing pump to increase the water pressure in the water supply waterway, and after increasing the power of the washing pump, performing the operation of S202 again; if it is detected that the detection circuit is in a connected state, the washing pump operation is controlled based on the increased power; conversely, if it is detected that the detection circuit is still in a disconnected state, the power of the washing pump is increased again until the detection circuit is in a connected state.

[0072] From the above, it can be seen that an abnormal response method based on a washing pump provided by an embodiment of the present invention is achieved by connecting a detection circuit in series in the circuit of the water pressure switch deployed in the water supply waterway of the washing pump, and obtaining the opening and closing status of the water pressure switch after the washing pump is started through the detection circuit. When the water pressure in the water supply waterway reaches a preset water pressure threshold, the water pressure switch will be closed, so that the loop where the detection circuit is located will be in a connected state, and when the water pressure does not reach the preset water pressure threshold, the water pressure switch will be disconnected, and then the loop where the detection circuit is located will also be in a disconnected state. Therefore, when the washing equipment detects that the detection circuit is in a disconnected state, it can identify that the water pressure in the current waterway is insufficient, and therefore will execute the abnormal response operation of the washing pump, thereby automatically repairing the insufficient water pressure situation. Compared with the existing control technology of smart home appliances, this embodiment can distinguish whether the abnormal water supply is caused by insufficient water pressure or water channel blockage, and when it is determined that the abnormality is caused by insufficient water pressure, it can perform corresponding abnormal response operations to achieve the repair of the abnormal situation, thereby improving the robustness of the washing equipment and reducing the probability of the washing equipment not being able to work normally due to the occurrence of abnormal situations.

[0073] Figure 3 The flowchart of the specific implementation of the abnormal response method based on the washing pump provided by the second embodiment of the present invention is shown. Figure 3 , relative to Figure 2 In the embodiment, a washing pump-based abnormal response method S203 provided in this embodiment includes: S2031 to S2033, which are described in detail as follows:

[0074] Furthermore, if the on-off state is the off state, performing an abnormal response operation on the washing pump includes:

[0075] In S2031, the washing pump is alternately turned on and off.

[0076] In this embodiment, when the electronic device detects that the water pressure switch has not reached the preset water pressure threshold, it may be due to excess gas in the washing pump, which affects the pressure increase of the washing pump and causes the water pressure to fail to reach the water pressure threshold. In this case, the washing device can alternately turn the washing pump on and off to expel the excess gas in the washing pump. During the process of alternating on and off of the washing pump, the washing device will obtain the on-off state of the detection circuit. If the on-off state of the detection circuit is connected at any time during the detection period, the operation of S2032 is executed; conversely, if the detection circuit is always disconnected during the detection period, the operation of S2033 is executed.

[0077] In S2032, if the on-off state of the detection circuit is detected to be the connected state within the preset detection time, the start instruction is re-executed.

[0078] In this embodiment, if the above-mentioned detection circuit of the washing equipment is in a connected state at a certain moment within the detection time, it means that the water supply waterway reaches the preset water pressure threshold at a certain moment, and it can be determined that the excess gas in the washing pump has been discharged, that is, the abnormal state has been automatically repaired. In this case, the washing equipment can re-send a start-up instruction to the washing pump in the washing equipment to continue to perform the corresponding washing operation.

[0079] Furthermore, as another embodiment of the present application, the above S2032 includes: S2032.1 to S2032.4, and after S2032, may further include: S2034 to S2035, which are specifically described as follows:

[0080] In S2032.1, a connectivity waveform diagram of the detection circuit is generated according to the connectivity time duration that the detection circuit is in the on-off state within the detection time duration.

[0081] In this embodiment, after the washing machine has exhausted excess gas from the washing pump, that is, when the water pressure in the water supply circuit reaches a preset water pressure threshold, the washing machine can not only continue the corresponding washing operation, but also determine multiple connection time periods corresponding to when the detection circuit is in a connection state, and generate corresponding connection waveforms based on the multiple connection time periods. In this connection waveform, the horizontal axis specifically represents the time axis, and the vertical axis can represent the identifier corresponding to the connection state.

[0082] For example, Figure 4Schematic diagram showing the comparison of the connectivity waveform diagram provided by an embodiment of the present application. Figure 4 As shown in (a) of the figure, the washing machine detects that the detection circuit has three connected time periods within the preset detection duration: T0, T1, and T2. Based on these three connected time periods, the detection circuit's connected duration within the detection duration is determined, and a corresponding connected waveform is generated. Based on this connected waveform, the washing machine can determine the corresponding on / off status of the detection circuit, that is, the specific time when the water supply pressure reaches the preset water pressure threshold.

[0083] In S2032.2, the connectivity inflection points included in the connectivity waveform are marked, and a plurality of connectivity time nodes for alternately turning the washing pump on and off are determined.

[0084] In this embodiment, after the washing machine generates the above-mentioned connectivity waveform diagram, the corresponding state change inflection points when the washing machine switches from the disconnected state to the connected state can be marked in the above-mentioned connectivity waveform diagram, that is, the above-mentioned connectivity inflection points. Figure 4 Correspondingly, the washing device can also generate a waveform diagram of the on-off state corresponding to the alternating on-off state of the washing pump, such as Figure 4 As shown in (b) of FIG, and based on the above on-off state waveform diagram, multiple connection time nodes corresponding to starting the washing pump are determined, such as Figure 4 Points Q0 to Q4 shown in (b) in FIG.

[0085] In S2032.3, a matching inflection point whose inflection point moment matches the connected time node is identified from all the connected inflection points.

[0086] In this embodiment, the washing machine can compare the two waveforms to identify the same time connection inflection points and connection time nodes, and use the same time connection inflection points in the on-off state waveform of the washing pump as the matching inflection points. Figure 4 Take this as an example to illustrate, Figure 4 (a) and Figure 4 From (b), we can see that the inflection point moment corresponding to the connected inflection point P0 is the same as the connected time node Q2. Therefore, the connected inflection point P0 is identified as the matching inflection point mentioned above. Similarly, P1 and P2 are also matching inflection points.

[0087] In S2032.4, the abnormal intake air volume before the washer pump is started is determined based on all the matching inflection points.

[0088] In this embodiment, after identifying all matching inflection points, the washing equipment can determine the time required to discharge excess gas in the washing pump, and based on the required time, calculate the abnormal air intake volume contained in the washing pump before startup.

[0089] In one possible implementation, the washing equipment stores a conversion function between the repair time and the intake air volume. The washing equipment can determine the inflection point moment of the earliest matching inflection point as the above-mentioned repair time, and import the repair time into the above-mentioned conversion function to calculate the corresponding abnormal intake air volume.

[0090] Furthermore, after S2032, the following steps may be included: S2034 to S2035, which are described in detail as follows:

[0091] In S2034 , in response to the shut-down instruction of the washer pump, an exhaust time period is determined based on the abnormal intake air volume.

[0092] In S2035 , the washing pump is alternately turned on and off within the exhaust time to exhaust the gas in the washing pump.

[0093] In this embodiment, when the washing equipment turns off the washing pump, in order to discharge excess gas in the washing pump and avoid insufficient air pressure due to excess gas in the washing pump when starting next time, the washing equipment will not directly turn off the washing pump when receiving the shutdown instruction of the washing pump, but will determine the corresponding exhaust time according to the above-mentioned abnormal air intake volume, and alternately turn on and off the above-mentioned washing pump within the exhaust time, so as to ensure that excess gas in the washing pump can be discharged.

[0094] In an embodiment of the present application, by determining the abnormal air intake volume and alternately turning the washing pump on and off when the washing pump is turned off to discharge the gas in the washing pump, the occurrence of insufficient water pressure due to excess gas remaining in the washing pump can be reduced, thereby improving the washing efficiency of the washing equipment.

[0095] In S2033, if the on-off state of the detection circuit is always in the off state within the detection time period, first abnormality information about the washing pump is output.

[0096] In this embodiment, if the washing device detects that the detection circuit is always in the disconnected state, it means that the water pressure in the water supply circuit is insufficient not due to the presence of excess gas, but may be due to damage to the washing pump and inability to work normally. At this time, the washing device will generate a first abnormality message to notify the user to repair the washing pump.

[0097] Furthermore, as another embodiment of the present application, the above S2033 further includes S2033.1 to S2033.3:

[0098] In S2033.1, the near field communication module is used to detect whether there is a wireless signal of the registered device in the scene.

[0099] In this embodiment, if the washing machine detects an abnormal state, it needs to notify the user of the current abnormality. The notification method can vary depending on whether the user is near the washing machine. To this end, the washing machine can use its near-field communication module to detect the presence of a wireless signal from a registered device in the current scene to determine whether the user is near the washing machine. The aforementioned level device is a device associated with a user account.

[0100] Among them, the above-mentioned near-field communication module can be a Bluetooth communication module, a Wi-Fi communication module, a low-power Bluetooth communication module, an NFC module or other modules.

[0101] In S2033.2, if the wireless signal of the registered device is detected, the first abnormal information is broadcasted through the speaker.

[0102] In this embodiment, if the washing device detects a wireless signal of a registered device in the current scene, it means that the user is near the washing device. At this time, the user can be notified of the abnormal situation through voice broadcast, so the first abnormal information generated can be broadcast through the speaker.

[0103] In S2033.3, if the wireless signal of any of the registered devices is not detected, the first abnormality information is uploaded to the server and the operation of the washing device is stopped; the server is used to send the first abnormality information to the registered device.

[0104] In this embodiment, if the washing device detects that the wireless signal of the registered device is not searched in the current scene, it means that the user is not near the washing device. At this time, the first abnormality information can be uploaded to the server, and the first abnormality information is sent to the registered device through the server to achieve the purpose of notifying the user of the fault situation.

[0105] In an embodiment of the present application, the user-associated registered device is searched through the near-field communication module to determine whether the user is near the washing device, and a corresponding notification method is used to achieve timeliness and flexibility of notification.

[0106] In an embodiment of the present application, the washing pump is alternately turned on and off to automatically repair the insufficient water pressure situation, and when automatic repair is not possible, a corresponding first abnormality message is generated to prompt the user to handle it, thereby improving the automatic repair capability of abnormal situations.

[0107] Figure 5 FIG3 shows a specific implementation flow chart of an abnormal response method based on a washing pump provided by the third embodiment of the present invention. Figure 5 , relative to Figure 2-4In any of the embodiments, the present embodiment provides a method for responding to an abnormality based on a washing pump, including S501 to S504, which are described in detail as follows:

[0108] Furthermore, the washing device further comprises a heating component, and the circuit where the heating component is located is connected in series with the water pressure switch; illustratively, Figure 6 The schematic diagram of the structure of the water supply circuit provided by an embodiment of the present application is shown. Figure 6 As shown, the water supply circuit not only includes a washing pump 61, a water pressure switch 62, and a detection circuit 63, but also includes a heating component 64 connected in series with the detection circuit. When water enters, the heating component can be used to heat the water to achieve the purpose of washing tableware with hot water.

[0109] In S501 , in response to a start instruction of the washing pump, the washing pump is turned on, including: if it is detected that the current stage is a heating and water supply stage, generating the start instruction and a heating instruction for the heating component.

[0110] In this embodiment, when the washing equipment needs to realize heated water supply, it is necessary not only to turn on the washing pump but also to start the heating component. Therefore, a corresponding heating instruction will be sent to the heating component so that when the water pressure meets the preset water pressure threshold, the above-mentioned heating component can be turned on to heat the water in the water supply waterway.

[0111] In S502 , the on / off state of the detection circuit is obtained.

[0112] Specifically, since the implementation process of S502 is exactly the same as the implementation process of S202, the specific description can refer to the relevant description of S202, which will not be repeated here.

[0113] In S503, the heating temperature of the heating component is obtained at preset time intervals.

[0114] In this embodiment, in order to prevent the heating component from burning dry, the washing machine will connect the heating component in series with the water pressure switch, that is, the state of the water pressure switch will directly affect the start state of the heating component. Figure 6 As shown in the figure, when the water pressure switch reaches the target position, the entire circuit is connected. At this time, water can be delivered to the washing chamber through the water outlet, and the heating component heats up, preventing dry-boiling. However, if the water pressure is insufficient, that is, the water pressure switch has not reached the target position, if the heating component is activated, dry-boiling is likely to occur due to the lack of flowing water. Therefore, connecting the heating component in series with the water pressure switch can improve the safety of the washing machine. However, if the heating component fails to heat up normally, it is impossible to distinguish whether the washing pump or the heating component is abnormal. Therefore, based on the above, a detection circuit is introduced to distinguish between these abnormal situations.

[0115] In this embodiment, the washing device can obtain the heating temperature of the heating component at a preset time interval and compare the heating temperature with the set temperature threshold. If the heating temperature is greater than or equal to the preset temperature threshold, it indicates that the heating component is in a normal working state; otherwise, if the heating temperature is less than the preset temperature threshold, the operation S504 is executed.

[0116] In S504 , if the detection circuit is in a connected state and the heating temperature is lower than a preset temperature threshold, second abnormality information about the heating component is generated.

[0117] In this embodiment, if the detection circuit is connected, it indicates that the washer pump is normal. However, if the heating component's temperature rise is less than a preset temperature threshold, it can be determined that the heating component is not functioning properly, indicating that the washer pump is abnormal, not the heating component. Therefore, second abnormality information regarding the heating component can be generated. Conversely, if the detection circuit is disconnected, it indicates that the washer pump is abnormal, and the aforementioned abnormality response operation is executed.

[0118] Furthermore, as another embodiment of the present application, the above S504 includes S5041 to S5044, which are specifically described as follows:

[0119] In S5041, a temperature deviation between the heating temperature and the temperature threshold is calculated.

[0120] In this embodiment, the washing machine can calculate the difference between the heating temperature and the temperature threshold, i.e., the aforementioned deviation temperature, and further classify the abnormality type of the heating component based on the deviation temperature. If the deviation temperature is greater than the reference heating threshold, operation S5042 is executed; otherwise, operation S5043 is executed.

[0121] In S5042, if the deviation temperature is greater than a preset reference temperature rise threshold, a third abnormality message is output; the third abnormality message is used to inform the user that the heating component is in an inoperative state.

[0122] In this embodiment, if the washing device detects that the deviation temperature is less than or equal to the baseline temperature rise threshold, it means that the heating component is in a state where it is completely unable to heat up normally. At this time, the washing device will generate a third abnormality message to prompt the user that the heating component is in a state where it is completely unable to work.

[0123] In S5043, if the deviation temperature is less than or equal to the reference temperature rise threshold, a first gear corresponding to the temperature rise temperature and a second gear corresponding to the temperature threshold are determined according to the correspondence between the temperature rise gear and the temperature rise amplitude.

[0124] In this embodiment, if the above-mentioned deviation temperature is less than or equal to the baseline temperature rise threshold, it means that the heating component can still heat up, but there is a certain deviation between the temperature rise amplitude and the expected amplitude, which may be caused by the basic water temperature being too low or the heating component power being insufficient. In this case, the washing equipment can determine the gear (i.e., the first gear) corresponding to the current temperature (i.e., the heating temperature) under the rated state, and the second gear corresponding to the expected temperature rise to the threshold, and can determine the degree of deviation between the actual gear and the expected gear.

[0125] In S5044, a gear adjustment coefficient is determined according to the first gear and the second gear, and the gear of the heating component is adjusted based on the gear adjustment coefficient.

[0126] In this embodiment, the washing equipment can calculate the corresponding gear adjustment coefficient based on the degree of deviation between the actual gear and the expected gear, and adjust the actual operating gear of the heating component based on the gear adjustment coefficient, and continue to heat the water in the water supply channel based on the adjusted gear during the heating and water supply stage to automatically repair the abnormal situation.

[0127] In the embodiment of the present application, the abnormality type of the heating component is determined by the degree of deviation between the heating temperature and the preset temperature threshold, which can improve the accuracy of abnormality identification and the accuracy of washing equipment control.

[0128] Figure 7 FIG4 shows a specific implementation flow chart of an abnormal response method S202 based on a washing pump provided by the fourth embodiment of the present invention. Figure 7 , relative to Figure 2-4 In any of the embodiments, the present embodiment provides a washing pump-based abnormal response method S202, which includes: S2021 to S2023, which are described in detail as follows:

[0129] Furthermore, the obtaining of the on / off state of the detection circuit includes:

[0130] In S2021, electrical index parameters of the detection circuit are obtained.

[0131] In S2022, if the electrical index parameter is greater than a preset index threshold, it is determined that the detection circuit is in a connected state.

[0132] In S2023 , if the electrical index parameter is less than or equal to a preset index threshold, it is determined that the detection circuit is in a disconnected state.

[0133] In this embodiment, the washing device can determine the on-off state corresponding to the detection circuit by detecting the electrical index parameters of the detection circuit. Since the operating environment of the washing device may be in an AC environment, there may be a certain degree of electrical jitter. Therefore, the corresponding index threshold can be set to divide the connected state and the disconnected state to improve the accuracy of the on-off state identification.

[0134] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0170] Therefore, the washing machine provided by the embodiment of the present invention can also be connected in series with a detection circuit within the circuit of the water pressure switch deployed in the water supply waterway of the washing pump. The detection circuit detects the open and closed state of the water pressure switch after the washing pump is started. When the water pressure in the water supply waterway reaches a preset water pressure threshold, the water pressure switch is closed, thereby placing the circuit containing the detection circuit in a connected state. When the water pressure does not reach the preset water pressure threshold, the water pressure switch is opened, and the circuit containing the detection circuit is also opened. Therefore, when the washing machine detects that the detection circuit is in the open state, it can identify that the water pressure in the current waterway is insufficient and execute an abnormal response operation of the washing pump, thereby automatically repairing the insufficient water pressure. Compared with existing smart home appliance control technologies, this embodiment can distinguish whether the abnormality caused by water supply anomaly is due to insufficient water pressure or due to waterway blockage. When it is determined that the abnormality is due to insufficient water pressure, it can execute the corresponding abnormal response operation to repair the abnormality, thereby improving the robustness of the washing machine and reducing the probability of the washing machine not being able to operate normally due to the abnormality.
