[0054] Reference is made to Figure 1 , Figure 1 is a structural schematic diagram of a washing equipment inner container provided by the embodiments of the application.

[0055] In an embodiment of the application, the bottom of the washing equipment inner container can further comprise a temperature sensor 6, a water inlet component 7 and a water inlet valve 8. The temperature sensor 6 is used for detecting the temperature value of the heating component 1, the water inlet component 7 is used for water inlet to the washing equipment inner container, and the water inlet valve 8 is used for controlling the opening and closing of the water inlet component 7.

[0056] Reference is made to Figure 2 ,Figure 2 is an implementation flowchart of a drain control method of a washing equipment provided by an embodiment of the present application. In the embodiment of the present application, the execution subject of the drain control method of the washing equipment is the washing equipment. The washing equipment can be a dishwasher.

[0057] As shown in Figure 2 , the drain control method of the washing equipment provided by an embodiment of the present application can include S101-S103, which are described in detail as follows:

[0058] In S101, in response to a drain instruction, a drain valve in a washing equipment inner container is opened, and a heating component located at the bottom of the inner container is opened.

[0059] In the embodiment of the present application, the washing equipment receiving a drain instruction can be that a preset operation for the washing equipment is detected by a user. The preset operation can be determined according to actual needs, which is not limited here. For example, the preset operation can be clicking a preset control. That is, if the washing equipment detects that a user clicks a preset control on the washing equipment, it is considered that the preset operation for the washing equipment is detected. Of course, the preset operation can also be a time trigger operation. The washing equipment can be configured with a corresponding washing process when it is running. The washing process includes a plurality of trigger nodes of key events. The above-mentioned key events include an event of draining the inner container of the washing equipment. In this case, if the washing equipment detects that the trigger node associated with the event of draining the inner container of the washing equipment is reached, the operation of S101-S103 is performed to perform the draining operation of the inner container of the washing equipment.

[0060] It should be noted that during the draining process of the inner container of the washing equipment, the water in the inner container will gradually decrease until only a layer of water film is attached to the bottom of the inner container. Since the water drained by the inner container is usually sewage, the residual water film not only reduces the drying degree of the inner container of the washing equipment, but also affects the subsequent use of the washing equipment. In order to improve the draining efficiency of the inner container and determine that the water in the inner container is completely drained, a heating component is further arranged at the bottom of the inner container. The heating component can be a heating disc.

[0061] Based on this, the washing equipment can open the drain valve in the inner container of the washing equipment in response to the drain instruction, and start the heating component located at the bottom of the inner container to achieve the purpose of heating and draining the inner container.

[0062] In an embodiment of the present application, in order to further improve the draining efficiency of the inner container, the washing equipment can specifically heat and drain the inner container through steps S201-S203 as shown in Figure 3 , which are described in detail as follows:

[0063] In S201, in response to a drain instruction, the amount of water to be drained in the inner container and the draining rate of the draining component are obtained.

[0064] In an implementation form of the present embodiment, the washing apparatus can obtain the to-be-drained amount of the inner container and the draining rate of the draining component in real time through a server connected to the washing apparatus wirelessly or by wire. The server can be a computer or a notebook computer or the like.

[0065] In some possible embodiments, since the draining rate of the draining component is usually set at the factory, the washing apparatus can obtain the draining rate of the draining component in advance and store the draining rate in the memory of the washing apparatus. When the washing apparatus receives the draining instruction, the washing apparatus can obtain the draining rate of the draining component from the memory of the washing apparatus.

[0066] In another possible embodiment, since the amount of water in the inner container changes only during the draining process, the to-be-drained amount of the inner container is equivalent to the water inflow amount of the inner container, that is, the washing apparatus can determine the to-be-drained amount of the inner container according to the water inflow amount of the inner container.

[0067] In S202, a draining duration is calculated according to the to-be-drained amount and the draining rate.

[0068] In S203, the draining valve and the heating component are opened for the draining duration.

[0069] In the present embodiment, the draining duration can be calculated according to the following formula:

[0070] T = Q / v T ;

[0071] wherein T represents the draining duration, Q represents the to-be-drained amount, and v T represents the draining rate of the draining component.

[0072] After obtaining the draining duration, the washing apparatus can determine the end time of the draining according to the start time of the draining and the draining duration, and thus the washing apparatus can open the draining valve of the inner container and the heating component at the bottom of the inner container in the time period from the start time of the draining to the end time of the draining, that is, for the draining duration. For example, assuming that the draining duration is 15 minutes and the start time of the draining is 11:20:00, the end time of the draining is 11:35:00, that is, the washing apparatus needs to keep opening the draining valve in the inner container and the heating component at the bottom of the inner container in the time period from 11:20:00 to 11:35:00.

[0073] As can be seen from the above, the washing apparatus can determine the draining duration of each time in real time according to the to-be-drained amount of the inner container, that is, the draining duration is not fixed but can be determined flexibly according to the to-be-drained amount, which not only improves the draining efficiency of the washing apparatus but also ensures that the water in the inner container is completely drained.

[0074] In S102, the temperature value of the heating component is sensed by the temperature controller at the bottom of the inner container; the temperature controller is used to disconnect when the sensed temperature value of the heating component is greater than a preset temperature threshold.

[0075] In the embodiments of the present application, when the washing equipment opens the drain valve in the inner container and starts the heating component at the bottom of the inner container, i.e., when the inner container is in the heating and draining stage, the washing equipment can sense the temperature value of the heating component through the temperature controller at the bottom of the inner container.

[0076] It should be noted that the temperature controller will automatically disconnect when the sensed temperature value of the heating component is greater than the preset temperature threshold. The preset temperature threshold can be set according to actual needs, which is not limited here. For example, in order to avoid the heating component being in a dry burning state when the water in the inner container is drained, the preset temperature threshold can be set according to the temperature value when the water film evaporates to produce steam when the inner container only has a layer of water film.

[0077] In some possible embodiments, in combination with S201-S203, after the washing equipment senses the temperature value of the heating component through the temperature controller at the bottom of the inner container, the washing equipment can detect the state of the temperature controller when the actual draining time of the inner container reaches the draining time.

[0078] In the embodiments, when the washing equipment detects that the actual draining time of the inner container reaches the draining time and the temperature controller is still in the connected state, the washing equipment performs steps S301-S303 as shown. Figure 4

[0079] In the embodiments, when the washing equipment detects that the actual draining time of the inner container reaches the draining time and the temperature controller is in the disconnected state, the washing equipment performs step S103.

[0080] In S103, when it is detected that the temperature controller is in the disconnected state, the drain valve and the heating component are closed.

[0081] In the embodiments of the present application, when the washing equipment detects that the temperature controller is in the disconnected state, it means that the temperature value of the heating component is greater than the preset temperature threshold, i.e., the heating component is in a dry burning state, and the water in the inner container has been drained. Therefore, the washing equipment can close the drain valve in the inner container and the heating component at the bottom of the inner container, i.e., stop the heating and draining operation of the inner container.

[0082] ​It can be seen from the above that the washing equipment drainage control method provided in the embodiment of the application opens the drainage valve in the inner container of the washing equipment in response to the drainage instruction, and starts the heating component located at the bottom of the inner container. Because the water in the inner container becomes less and less and the temperature becomes higher and higher after the above-mentioned drainage operation and heating operation are performed on the inner container of the washing equipment, the temperature value of the heating component can be sensed by the temperature controller at the bottom of the inner container, and the temperature controller is used to be disconnected when the sensed temperature value of the heating component is greater than a preset temperature threshold. Because the heating operation of the heating component at the bottom of the inner container does not stop when the water in the inner container is drained, dry burning of the heating component occurs, so that the temperature value of the heating component exceeds the preset temperature threshold. Therefore, when it is detected that the temperature controller is in the disconnected state, it is determined that the heating component is in the dry burning state, that is, it is determined that the water in the inner container has been drained, and the drainage valve in the inner container of the washing equipment and the heating component at the bottom of the inner container can be closed, so that the inner container is prevented from being dry burned, and the service life of the washing equipment is prolonged. The washing equipment drainage control method provided in the embodiment of the application improves the drainage efficiency and can ensure that the water in the inner container has been drained.

[0083] Please refer to Figure 4 , Figure 4 is the implementation flowchart of the washing equipment drainage control method provided in another embodiment of the application. Compared with Figure 2 the corresponding embodiment, the washing equipment drainage control method provided in the embodiment further includes S301-S303 after S102, which are described in detail as follows.

[0084] In S301, if the temperature controller is still in the connected state when the actual drainage time length reaches the drainage time length, the temperature value of the heating component is determined by the temperature sensor.

[0085] In the embodiment, when the washing equipment detects that the actual drainage time length of the inner container reaches the drainage time length and the temperature controller is still in the connected state, the washing equipment can determine the temperature value of the heating component at this time by the temperature sensor, and compare the temperature value of the heating component at this time with the preset temperature threshold.

[0086] It can be understood that the washing equipment can receive the signal value fed back by the temperature sensor, and determine the temperature value of the heating component according to the signal value fed back by the temperature sensor.

[0087] If the washing equipment detects that the temperature value of the heating component at this time is greater than the preset temperature threshold, step S302 is performed; and if the washing equipment detects that the temperature value of the heating component at this time is less than the preset temperature threshold, step S303 is performed.

[0088] In S302, if the temperature value of the heating component is greater than the preset temperature threshold, first prompt information is output; and the first prompt information is used to prompt that the temperature controller is abnormal.

[0089] In this embodiment, when the washing equipment detects that the temperature value of the heating component at this time is greater than the preset temperature threshold, it indicates that the heating component is in a dry burning state at this time, and the temperature controller should be disconnected. However, the temperature controller at this time is still in a connected state, indicating that the temperature controller is abnormal. Therefore, the washing equipment can output first prompt information for prompting the abnormality of the temperature controller, facilitating the maintenance or replacement of the temperature controller by relevant personnel.

[0090] In an embodiment of the present application, when the washing equipment outputs the first prompt information, since the heating component is in a dry burning state at this time, that is, the water in the inner container has been drained, the washing equipment can also close the drain valve in the inner container and the heating component at the bottom of the inner container, so as to reduce the power consumption of the washing equipment and prolong the service life of the washing equipment.

[0091] In S303, if the temperature value of the heating component is less than the preset temperature threshold, the drain valve and the heating component are kept in an open state until the temperature value of the heating component is greater than the preset temperature threshold, and second prompt information is outputted; the second prompt information is used to prompt the abnormality of the drain component.

[0092] In this embodiment, when the washing equipment detects that the temperature value of the heating component is less than the preset temperature threshold, it indicates that the water in the inner container has not been completely drained by the drain component within the drain duration, that is, the drain component is abnormal and cannot drain the water in the inner container on time. Therefore, in order to improve the drain success rate and ensure that the water in the inner container is completely drained, the washing equipment needs to keep the drain valve in the inner container and the heating component at the bottom of the inner container in an open state until the temperature value of the heating component is greater than the preset temperature threshold, and output second prompt information for prompting the abnormality of the drain component, so as to facilitate the inspection and maintenance of the drain component by relevant personnel in time.

[0093] As can be seen from the above, the drain control method of the washing equipment provided in this embodiment can determine the temperature value of the heating component through the temperature sensor when the temperature controller is still in a connected state when the actual drain duration reaches the drain duration, output first prompt information for prompting the abnormality of the temperature controller when the temperature value of the heating component is greater than the preset temperature threshold, keep the drain valve and the heating component in an open state when the temperature value of the heating component is less than the preset temperature threshold until the temperature value of the heating component is greater than the preset temperature threshold, and output second prompt information for prompting the abnormality of the drain component, so as to ensure that the drain valve and the heating component are closed only when the water in the inner container is drained, and improve the drain success rate.

[0094] Please refer to Figure 5 , Figure 5is an implementation flowchart of a drainage control method of a washing equipment provided by another embodiment of the present application. Compared with Figure 2 In a corresponding embodiment, the drainage control method of the washing equipment provided by the present embodiment can further include S401-S403 after S101, which are described as follows.

[0095] In S401, a signal value fed back by a temperature sensor located at the bottom of the inner container is read at a preset collection period to determine the temperature value of the heating component.

[0096] In the present embodiment, a temperature sensor is also installed at the bottom of the inner container of the washing equipment, therefore, the washing equipment can read the signal value fed back by the temperature sensor located at the bottom of the inner container at a preset collection period, and determine the temperature value of the heating component according to the signal value.

[0097] The preset collection period can be set according to actual needs, which is not limited here. For example, since the more water in the inner container, the slower the temperature changes, the preset collection period can be determined according to the amount of water to be drained, that is, the more the amount of water to be drained, the longer the preset collection period.

[0098] If the washing equipment does not receive the signal value fed back by the temperature sensor within the preset collection period, step S402 is performed.

[0099] If the washing equipment can receive the signal value fed back by the temperature sensor within the preset collection period, step S403 is performed.

[0100] In S402, if the signal value fed back by the temperature sensor is not received within the collection period, third prompt information is outputted; the third prompt information is used to prompt that the temperature sensor is abnormal.

[0101] In the present embodiment, when the washing equipment does not receive the signal value fed back by the temperature sensor within the preset collection period, it indicates that the temperature sensor is abnormal and cannot detect the temperature value of the heating component, therefore, the washing equipment can output the third prompt information for prompting that the temperature sensor is abnormal, so that the relevant personnel can replace the temperature sensor in time.

[0102] In S403, if the signal value fed back by the temperature sensor is received within the collection period, a first temperature difference value between the temperature value of the heating component in the collection period and the temperature value of the heating component in the last collection period is calculated, and the state of the drainage component and the heating component is determined according to the first temperature difference value.

[0103] In this embodiment, when the washing equipment receives the signal value fed back by the temperature sensor within the preset collection period, it is indicated that the temperature sensor is normal and the temperature value of the heating component can be detected. Therefore, the washing equipment can determine the temperature value of the heating component in the preset collection period according to the received signal value fed back by the temperature sensor, calculate the first temperature difference between the temperature value in the preset collection period and the temperature value in the last collection period, and determine the state of the draining component and the heating component according to the first temperature difference.

[0104] In one embodiment of the present application, the washing equipment can specifically determine the state of the heating component through steps S501 as shown in the following table: Figure 6

[0105] In S501, if the first temperature difference between any two adjacent collection periods in the N collection periods is zero, it is determined that the heating component is abnormal, and fourth prompt information is output. The fourth prompt information is used to prompt that the heating component is abnormal, and N≥3.

[0106] In this embodiment, when the washing equipment detects that the first temperature difference between any two adjacent collection periods in the N preset collection periods is zero, it is indicated that the temperature of the water in the inner container does not change, that is, the heating component does not heat the water in the inner container, which means that the heating component is abnormal. Therefore, the washing equipment can determine that the state of the heating component is an abnormal state, and output fourth prompt information for prompting that the heating component is abnormal, so as to facilitate the inspection and maintenance of the heating component by relevant personnel.

[0107] In another embodiment of the present application, the washing equipment can specifically determine the state of the draining component through steps S601-S602 as shown in the following table: Figure 7

[0108] In S601, if the first temperature difference is greater than zero and less than a first preset difference threshold, the temperature value in the next collection period is obtained, and a second temperature difference between the temperature value in the next collection period and the temperature value in the preset collection period is calculated.

[0109] In this embodiment, when the washing equipment detects that the first temperature difference is greater than zero and less than a first preset difference threshold, it is indicated that there is still water in the inner container and the temperature of the water is changing, that is, the heating component at the bottom of the inner container is normal. In order to determine whether the draining component is normal, the washing equipment can obtain the temperature value in the next collection period and calculate the second temperature difference between the temperature value in the next collection period and the temperature value in the preset collection period. The first preset difference threshold can be set according to actual needs, which is not limited here. For example, the first preset difference threshold can be set as the temperature difference between the temperature values before and after the water film generates steam. ​​

[0110] After obtaining the second temperature difference value, the washing appliance can compare the second temperature difference value with the first temperature difference value. If the washing appliance detects that the second temperature difference value is equal to the first temperature difference value, step S602 is performed.

[0111] In S602, if the second temperature difference value is equal to the first temperature difference value, it is determined that the drainage component is abnormal, and fifth prompt information is output. The fifth prompt information is used to prompt that the drainage component is abnormal.

[0112] In this embodiment, when the washing appliance detects that the second temperature difference value is equal to the first temperature difference value, it means that the temperature variation range of the water in the inner container is completely the same in the same collection period, that is, the water in the inner container has not been reduced, that is, the water in the inner container has not been drained, and the drainage component of the washing appliance is abnormal. Therefore, the washing appliance can determine that the drainage component is in an abnormal state, and output fifth prompt information for prompting that the drainage component is abnormal.

[0113] As can be seen from the above, the washing appliance drainage control method provided in this embodiment determines the temperature value of the heating component by reading the signal value fed back by the temperature sensor located at the bottom of the inner container in a preset collection period, and outputs third prompt information for prompting that the temperature sensor is abnormal when no signal value fed back by the temperature sensor is received in the collection period. When the signal value fed back by the temperature sensor is received in the collection period, the first temperature difference value between the temperature value of the heating component in the collection period and the temperature value of the heating component in the last collection period can be calculated, and the state of the drainage component and the heating component can be determined according to the first temperature difference value. Therefore, whether the temperature sensor, the drainage component and the heating component are abnormal can be understood in time, so that relevant personnel can perform maintenance or replacement, thereby improving the drainage success rate of the washing appliance.

[0114] Please refer to Figure 8 , Figure 8 is the implementation flowchart of the washing appliance drainage control method provided in another embodiment of the present application. Compared with Figure 5 Corresponding to the embodiment, the washing appliance drainage control method provided in this embodiment can specifically include S701, which is described in detail as follows.

[0115] In S701, if the first temperature difference value is less than a second preset difference threshold value, sixth prompt information is output. The sixth prompt information is used to prompt that the water inlet valve in the inner container is in an open state, and the second preset difference threshold value is less than zero.

[0116] In this embodiment, when the washing device detects that the first temperature difference is less than the second preset difference threshold, it means that the water in the inner tank has not been drained and the water temperature is dropping. Since the heating component is still heating at this time, it can be determined that water is entering the inner tank, which causes the amount of water in the inner tank to increase and the temperature to drop. In other words, the water inlet valve of the inner tank is in the open state. Therefore, the washing device can output a sixth prompt information for prompting that the water inlet valve in the inner tank is in the open state, so that relevant personnel can close the water inlet valve in time.

[0117] From the above, it can be seen that the drainage control method for washing equipment provided in this embodiment can output a fifth prompt information for prompting that the water inlet valve in the inner tank is in an open state when it detects that the first temperature difference is less than the second preset difference threshold, so that relevant personnel can close the water inlet valve, thereby improving drainage efficiency.

[0118] 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 this application.

[0119] Corresponding to the drainage control method of a washing device described in the above embodiment, Figure 8 The structural block diagram of a drainage control device provided by an embodiment of the present application is shown. For the sake of convenience, only the parts related to the embodiment of the present application are shown.

[0126] The second opening unit is configured to open the draining valve and the heating component for the draining duration.

[0127] In an embodiment of the present application, the draining control device 800 further comprises a determination unit, a first output unit and a second output unit, wherein:

[0128] The determination unit is configured to determine the temperature value of the heating component by the temperature sensor if the temperature controller is still in the connected state when the actual draining duration reaches the draining duration.

[0129] The first output unit is configured to output a first prompt information if the temperature value of the heating component is greater than a preset temperature threshold; the first prompt information is used to prompt that the temperature controller is abnormal.

[0130] The second output unit is configured to keep the draining valve and the heating component in the opened state until the temperature value of the heating component is greater than the preset temperature threshold if the temperature value of the heating component is less than the preset temperature threshold, and output a second prompt information; the second prompt information is used to prompt that the draining component is abnormal.

[0131] In an embodiment of the present application, the draining control device 800 further comprises a reading unit, a third output unit and a second calculation unit, wherein:

[0132] The reading unit is configured to read the signal value fed back by the temperature sensor located at the bottom of the inner container at a preset collection period, and determine the temperature value of the heating component.

[0133] The third output unit is configured to output a third prompt information if the signal value fed back by the temperature sensor is not received in the collection period; the third prompt information is used to prompt that the temperature sensor is abnormal.

[0134] The second calculation unit is configured to calculate a first temperature difference value between the temperature value of the heating component in the collection period and the temperature value of the heating component in the last collection period if the signal value fed back by the temperature sensor is received in the collection period, and determine the state of the draining component and the heating component according to the first temperature difference value.

[0135] In an embodiment of the present application, the second calculation unit specifically comprises a fourth output unit.

[0136] The fourth output unit is configured to determine that the heating component is abnormal and output fourth prompt information if the first temperature difference between any two adjacent collection periods in the N collection periods is zero, wherein N is greater than or equal to 3.

[0137] In an embodiment of the present application, the second calculation unit specifically includes a second acquisition unit and a fifth output unit. Wherein:

[0138] The second acquisition unit is configured to acquire a temperature value of a next collection period and calculate a second temperature difference between the temperature value of the next collection period and the preset collection period if the first temperature difference is greater than zero and less than a first preset difference threshold.

[0142] As can be seen from the above, the drainage control device of the washing equipment provided by the embodiments of the present application can open the drainage valve in the inner container of the washing equipment and start the heating component located at the bottom of the inner container in response to the drainage instruction. After the above drainage operation and heating operation on the inner container of the washing equipment, the water in the inner container will become less and less, and the temperature will also become higher and higher. Therefore, the temperature value of the heating component can be sensed by the temperature controller at the bottom of the inner container, wherein the temperature controller is used to be disconnected when the temperature value of the heating component sensed is greater than a preset temperature threshold. Since the heating operation of the heating component at the bottom of the inner container does not stop when the water in the inner container is drained, the heating component will be dry-burned, so that the temperature value of the heating component exceeds the preset temperature threshold. Therefore, when it is detected that the temperature controller is in a disconnected state, it indicates that the heating component is in a dry-burning state, that is, it can be determined that the water in the inner container has been drained. The drainage valve in the inner container of the washing equipment can be closed and the heating component at the bottom of the inner container can be closed, so as to avoid dry-burning of the inner container and prolong the service life of the washing equipment. The drainage control method of the washing equipment provided by the embodiments of the present application improves the drainage efficiency and can ensure that the water in the inner container has been drained.
