[0002] At present, when a washing machine runs a washing program, it is usually necessary to heat the washing water for a period of time to clean the grease on the dishes to be washed. Therefore, the washing machine is generally provided with a heating program.

[0037] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0038] The embodiment of the present application provides a heating detection method for a washing device. Since the water that usually enters the inner tank of the washing device is hot water (higher than normal temperature), and the temperature of the inner tank at this time is normal temperature, that is, the temperature of the inner tank at this time is lower than the temperature of the hot water. At the same time, since the inner tank absorbs heat, although the water is heated, the heating speed is far slower than the heat dissipation speed. Therefore, there is a time period in which the temperature first drops and then rises during the heating stage. Therefore, when it is detected that the inner tank of the washing device is in the heating stage, a first temperature value of the water in the inner tank can be obtained first; then, a second temperature value set of the water is obtained within a first preset heating time period, and the start time of the first preset heating time period is the next time to obtain the first temperature value; and when it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, it indicates that the first temperature value is the lowest temperature. Therefore, it can be determined that the first temperature value is the initial temperature value. At this time, multiple third temperature values ​​after the initial temperature value can be collected at a preset first time interval, and when it is detected that the difference between any third temperature value and the reference temperature value obtained in the collection process is greater than the temperature threshold, a response signal indicating that the heating stage is normal can be generated. The heating detection method for the washing equipment provided in the embodiment of the present application will start to detect whether the heating stage of the washing equipment is normal only after the lowest temperature (ie, the initial temperature) is determined, thereby improving the detection accuracy.

[0054] See also Figure 1 , Figure 1 This is a flow chart of a method for detecting heating of a washing device provided in an embodiment of the present application. In the embodiment of the present application, the subject of executing the method for detecting heating of a washing device is a washing device, wherein the washing device may be a dishwasher.

[0055] like Figure 1 As shown, the heating detection method for a washing device provided in an embodiment of the present application may include S101 to S104, which are described in detail as follows:

[0056] In S101, when it is detected that the inner tank of the washing device is in a heating stage, a first temperature value of the water in the inner tank is obtained.

[0057] In the embodiment of the present application, the washing device detecting that the inner tank of the washing device is in the heating stage may be: detecting that a heating component located inside the inner tank of the washing device is in an on state. The heating component may be a heating plate.

[0058] In one implementation of the embodiment of the present application, the washing device can read a first signal value fed back by a temperature sensor located inside the inner tank of the washing device, and determine a first temperature value of water in the inner tank according to the first signal value.

[0059] In the embodiment of the present application, when the washing machine detects that the inner tank of the washing machine is in the heating stage, it can randomly obtain the temperature value of the water in the inner tank at a certain moment, and determine the temperature value of the water at that moment as the first temperature value. Exemplarily, the washing machine can determine the temperature value of the water in the inner tank detected when the heating component is turned on as the first temperature value.

[0060] In S102, a second temperature value set of the water is obtained within a first preset heating time period; the start time of the first preset heating time period is the next time when the first temperature value is obtained.

[0061] In the embodiment of the present application, in order to determine whether the first temperature value is the lowest temperature value of the water in the heating stage, the washing device can continue to obtain a set of second temperature values ​​of the water in the first preset heating time period after obtaining the first temperature value of the water. The first preset heating time period can be set according to actual needs and is not limited here.

[0062] In one implementation of the embodiment of the present application, each second temperature value in the second temperature value set may be a temperature value of water collected at a preset third time interval during the first preset heating period. The preset third time interval may be set according to actual needs and is not limited here.

[0063] It should be noted that, in order to improve the accuracy of determining the lowest temperature value of the water in the inner tank of the washing device, the start time of the first preset heating time period may be the next time when the first temperature value is obtained.

[0064] In actual applications, when the washing machine washes the dishes to be washed in the inner tank, hot water is usually injected into the inner tank and the hot water is heated. However, at this time, the temperature of the inner tank is at room temperature, that is, lower than the temperature of the hot water. At this time, the inner tank will begin to absorb heat. That is to say, although the hot water injected into the inner tank is heated, its heating speed is far slower than its heat dissipation speed. Therefore, the temperature of the hot water injected into the inner tank will first drop and then rise again. Therefore, the first preset heating time period can be set according to the time for the temperature of the hot water injected into the inner tank to drop. For example, the first preset heating time period can be set to 2 minutes.

[0065] In the embodiment of the present application, after the washing device has obtained a set of second temperature values ​​for water, it can sequentially compare each second temperature value in the set of second temperature values ​​with the first temperature value.

[0066] In one embodiment of the present application, when the washing device detects that each second temperature value in the second temperature value set is greater than the first temperature value, steps S103 to S104 may be executed.

[0067] In another embodiment of the present application, when the washing device detects that there is a target temperature value less than the first temperature value in the second temperature value set, the washing device may perform the following steps: Figure 2 S201~S202 shown.

[0068] In S103, if it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, the first temperature value is determined to be an initial temperature value, and multiple third temperature values ​​after the initial temperature value are collected at a preset first time interval.

[0069] In the embodiment of the present application, when the washing device detects that each second temperature value in the second temperature value set is greater than the first temperature value, it indicates that the first temperature value is the lowest temperature value of water. Therefore, the washing device can determine the first temperature value as the initial temperature value.

[0070] After determining the initial temperature value, the washing device can start to detect whether the temperature value of the water in the inner pot in the heating stage is in an ascending state. Therefore, at this time, the washing device can collect multiple third temperature values ​​after the initial temperature value at a preset first time interval. Among them, the preset first time interval can be set according to actual needs and is not limited here. It should be noted that since the temperature value of the water will not change in a very short time, the preset first time interval can be set according to the time when the temperature value of the water changes.

[0071] It should be noted that the third temperature value may be any second temperature value in the above-mentioned set of second temperature values ​​that are all greater than the first temperature value, or may be a temperature value at any time after the first preset heating time period, and is not limited here.

[0072] In one embodiment of the present application, after obtaining the above-mentioned multiple third temperature values, the washing device can calculate the difference between any third temperature value and the reference temperature value obtained in the collection process.

[0073] It should be noted that the reference temperature value may be an initial temperature value, or another temperature value collected at a time later than the initial temperature value and different from any of the third temperature values.

[0074] After obtaining the difference between any of the third temperature values ​​and the reference temperature value obtained during the collection process, the washing device can compare the difference with the temperature threshold. The temperature threshold is determined based on the difference between the collection time of any of the third temperature values ​​and the collection time of the reference temperature value. In other words, if the difference between the collection time of any of the third temperature values ​​and the collection time of the reference temperature value is different, the corresponding temperature threshold is also different.

[0075] Based on this, in one embodiment of the present application, when the reference temperature value is the initial temperature value, the washing device can calculate the difference between any third temperature value and the initial temperature value, and compare the difference with the second temperature threshold value. The second temperature threshold value is determined by the difference between the collection time of any third temperature value and the collection time of the initial temperature value.

[0076] In another embodiment of the present application, when the reference temperature value is another temperature value that is collected after the collection time of the initial temperature value and is different from any of the third temperature values, the washing device can calculate the difference between the third temperature value and the other temperature value, and compare the difference with a third temperature threshold value. The third temperature threshold value is determined by the difference between the collection time of any of the third temperature values ​​and the collection time of the other temperature value.

[0077] In the embodiment of the present application, when the washing device detects that the difference between any third temperature value and the reference temperature value obtained during the collection process is greater than the temperature threshold, step S104 may be executed.

[0078] In another embodiment of the present application, when the washing device detects that the difference between any one of the third temperature values ​​and the reference temperature value obtained during the acquisition process is less than the temperature threshold, it indicates that although the temperature of the water in the inner tank has increased, the temperature change is not obvious, that is, the heating component is in normal working condition and there is no abnormality. However, an abnormality occurs in the heating stage. For example, the water inlet valve in the inner tank of the washing device is in an open state, resulting in excessive water inflow into the inner tank, causing the water temperature to rise slowly. Therefore, the washing device can output a first prompt message for prompting an abnormality in the heating stage, so that relevant personnel can conduct relevant inspections on the washing device as soon as possible.

[0079] In S104, if it is detected that the difference between any of the third temperature values ​​and the reference temperature value obtained during the acquisition process is greater than or equal to the temperature threshold, a response signal is generated; the response signal indicates that the heating stage is normal.

[0080] In an embodiment of the present application, when the washing device detects that the difference between any third temperature value and the reference temperature value obtained during the acquisition process is greater than the temperature threshold, it indicates that the heating component is normal and the heating stage is also in a normal state. Therefore, the washing device can generate a response signal indicating that the heating stage is normal.

[0081] Specifically, in combination with S103, when the washing device detects that the difference between any third temperature value and the initial temperature value is greater than or equal to the second temperature threshold, it indicates that the heating component is normal and the heating stage is also in a normal state. Therefore, the washing device can generate a response signal indicating that the heating stage is normal.

[0082] When the washing device detects that the difference between any third temperature value and another temperature value is greater than or equal to the third temperature threshold, it indicates that the heating component is normal and the heating stage is also in a normal state. Therefore, the washing device can generate a response signal indicating that the heating stage is normal.

[0083] From the above, it can be seen that in the heating detection method for a washing device provided by the embodiment of the present application, since the water that usually enters the inner tank of the washing device is hot water (higher than normal temperature), and the temperature of the inner tank at this time is normal temperature, that is, the temperature of the inner tank at this time is lower than the temperature of the hot water, and at the same time, because the inner tank absorbs heat, although the water is being heated, the heating speed is far slower than the heat dissipation speed, so there is a time period in which the temperature first drops and then rises during the heating stage. Therefore, when it is detected that the inner tank of the washing device is in the heating stage, the first temperature value of the water in the inner tank can be obtained first; then, a second temperature value set of the water is obtained within a first preset heating time period, and the start time of the first preset heating time period is the next time to obtain the first temperature value; and when it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, it indicates that the first temperature value is the lowest temperature, and therefore, it can be determined that the first temperature value is the initial temperature value, and at this time, multiple third temperature values ​​after the time of the initial temperature value can be collected at a preset first time interval, and when it is detected that the difference between any third temperature value and the reference temperature value obtained during the collection process is greater than or equal to the temperature threshold, a response signal indicating that the heating stage is normal can be generated. The heating detection method for the washing equipment provided in the embodiment of the present application will start to detect whether the heating stage of the washing equipment is normal only after the lowest temperature (ie, the initial temperature) is determined, thereby improving the detection accuracy.

[0084] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of a method for detecting heating of a washing machine provided in another embodiment of the present application. Figure 1 Corresponding to the embodiment, the heating detection method for washing equipment provided in this embodiment further includes S201 to S202 after S102, which are described in detail as follows:

[0085] In S201, if it is detected that there is a target temperature value smaller than the first temperature value in the second temperature value set, the first temperature value is updated based on the target temperature value, and the first preset heating time period is updated according to the target temperature value.

[0086] In S202, based on the updated first temperature value and the updated first preset heating time period, the operation of obtaining a second temperature value set of the water within the first preset heating time period is returned to be executed until each second temperature value in the re-acquired second temperature value set is greater than the updated first temperature value.

[0087] It should be noted that the second temperature value in the second temperature value set that is smaller than the first temperature value may be one or more.

[0088] In one embodiment of the present application, when there is only one second temperature value that is less than the first temperature value in the second temperature value set, the washing device may directly determine the second temperature value as the target temperature value.

[0089] In another embodiment of the present application, when there are multiple second temperature values ​​that are lower than the first temperature value in the second temperature value set, the washing device may compare the multiple second temperature values ​​one by one, determine the one with the smallest temperature value among the multiple second temperature values, and determine the one with the smallest temperature value as the target temperature value.

[0090] In some possible embodiments, when the washing device obtains two adjacent second temperature values ​​within the first preset time period at a preset second time interval that is too short, it may easily lead to a situation where multiple second temperature values ​​are the same, that is, there are multiple second temperature values ​​with the smallest temperature values ​​in the second temperature value set. At this time, the washing device may determine, among the multiple second temperature values ​​with the smallest temperature values, the second temperature value with the largest time difference between the collection time and the start time of the first preset time period as the target temperature value.

[0091] In this embodiment, when the washing device detects that there is a target temperature value lower than the first temperature value in the second temperature value set, it means that the first temperature value obtained by the washing device in S101 is not the lowest temperature value of the water in the inner tank (i.e., the initial temperature value). Therefore, in order to redetermine the initial temperature value of the water, the washing device can update the obtained first temperature value based on the above target temperature value, and update the first preset heating time period according to the target temperature value.

[0092] It is understandable that the washing machine can determine the target temperature value as a new first temperature value, and determine the next moment when the target temperature value is obtained as the start moment of a new first preset heating time period.

[0093] Based on this, the washing device can return to execute step S102, that is, obtain a second temperature value set within the updated first preset heating time period, and continue to compare each second temperature value in the second temperature value set with the updated first temperature value (that is, the target temperature value) one by one until each second temperature value in the re-acquired second temperature value set is greater than the updated first temperature value.

[0094] From the above, it can be seen that the heating detection method for washing equipment provided by this embodiment, when detecting that there is a target temperature value less than the first temperature value in the second temperature value set, indicates that the first temperature value obtained before is not the lowest temperature value. Therefore, the first temperature value can be updated based on the target temperature value, and the first preset heating time period can be updated according to the target temperature value, and according to the updated first temperature value and the updated first preset heating time period, the operation of obtaining the second temperature value set of water within the first preset heating time period is returned to execute until each second temperature value in the re-acquired second temperature value set is greater than the updated first temperature value. The heating detection method for washing equipment provided by this embodiment can accurately obtain the lowest temperature value (i.e., the initial temperature value) of water in the heating stage, thereby improving the accuracy of the later heating detection.

[0095] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of a method for detecting heating of a washing machine provided in another embodiment of the present application. Figure 1 In the corresponding embodiment, the heating detection method for washing equipment provided in this embodiment, S103 may include S301, and correspondingly, S104 may include S302, which is described in detail as follows:

[0096] In S401, if it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, the first temperature value is determined to be an initial temperature value, and a fourth temperature value of the water after a second preset heating time period is obtained.

[0097] In this embodiment, when the washing device detects that each second temperature value in the second temperature value set is greater than the first temperature value, it indicates that the first temperature value is the lowest temperature value of water. Therefore, the washing device can determine the first temperature value as the initial temperature value.

[0098] After determining the initial temperature value, the washing machine needs to detect whether the temperature value of the water in the inner tank is in an increasing state during the heating temperature stage in order to improve the detection accuracy. Therefore, the washing machine can obtain the fourth temperature value of the water after the second preset heating time period. The second preset heating time period can be set according to actual needs and is not limited here.

[0099] It should be noted that the second preset heating time period refers to a period of time after the first preset heating time period.

[0100] In one implementation of this embodiment, the washing device can read a second signal value fed back by a temperature sensor located inside the inner tank of the washing device after a second preset heating time period, and determine a fourth temperature value of water according to the second signal value.

[0101] In one embodiment of the present application, after obtaining the fourth temperature value, the washing device may directly compare the fourth temperature value with the above initial temperature value (ie, the first temperature value).

[0102] In this embodiment, when the washing device detects that the fourth temperature value is equal to the initial temperature value, it means that the temperature of the water in the inner tank has not risen within the second preset heating time period, that is, the heating component has not heated the water in the inner tank of the washing device within the second preset heating time period, that is to say, the heating component has an abnormality. Therefore, the washing device can output a second prompt message for prompting that the heating component has an abnormality, so that relevant personnel can repair or replace the heating component in time.

[0103] In another embodiment of the present application, after obtaining the fourth temperature value, the washing device may calculate the difference between the fourth temperature value and the initial temperature value (i.e., the first temperature value), and compare the difference with the first temperature threshold value, wherein the first temperature threshold value is determined by the difference between the time when the fourth temperature value is collected and the time when the initial temperature value is collected.

[0104] In one embodiment of the present application, when the washing device detects that the difference between the fourth temperature value and the initial temperature value is greater than or equal to the first temperature threshold, step S302 may be executed.

[0105] In another embodiment of the present application, when the washing device detects that the difference between the above-mentioned fourth temperature value and the initial temperature value is less than the second preset threshold value, it indicates that although the temperature of the water in the inner tank has increased during the second preset heating time period, it has not reached the ideal rising state, that is, the heating component is in a normal working state during the second preset heating time period, and no abnormality occurs. However, an abnormality occurs in the heating stage. For example, the water inlet valve in the inner tank of the washing device is in an open state, resulting in excessive water inflow into the inner tank, causing the water temperature to rise slowly. Therefore, the washing device can output a second prompt message for prompting an abnormality in the heating stage, so that relevant personnel can conduct relevant inspections on the washing device as soon as possible.

[0106] In one embodiment of the present application, in order to determine whether the water is in a temperature stable rising stage (i.e., a heating stable stage) in the second preset heating time period, so that the fourth temperature value obtained after the second preset heating time period is the temperature value obtained by the water after the heating stable stage, the washing device can specifically perform the following steps: Figure 4 Steps S401 to S403 are described in detail as follows:

[0107] In S401, a plurality of fifth temperature values ​​of the water in the second preset heating time period are obtained at preset second time intervals.

[0108] In S402, a temperature curve graph is constructed according to the plurality of fifth temperature values ​​and the collection moments respectively corresponding to the plurality of fifth temperature values.

[0109] In S403, if it is detected that the slope of the temperature curve is greater than or equal to a slope threshold, a fourth temperature value of the water after the second preset heating time period is acquired.

[0110] In this embodiment, the preset second time interval can be set according to actual needs and is not limited here. Exemplarily, the preset second time interval can be 10 seconds.

[0111] After obtaining multiple fifth temperature values, the washing device can construct a temperature curve graph of water in the second preset heating time period according to the multiple fifth temperature values ​​and the collection time corresponding to each fifth temperature value, and determine the slope of the temperature curve graph.

[0112] After obtaining the slope of the temperature curve, the washing device can compare the slope with the slope threshold. The slope threshold can be set according to actual needs and is not limited here. For example, the slope threshold can be set according to the slope when the water temperature is in a stable rising stage.

[0113] In this embodiment, when the washing device detects that the slope of the above-mentioned temperature curve graph is greater than or equal to the slope threshold, it indicates that the temperature of the water in the inner tank is in a stable rising stage within the second preset heating time period. Therefore, the washing device can obtain the fifth temperature value of the water after the second preset heating time period.

[0114] In another embodiment of the present application, the heating stage may include a preheating stage and an actual heating stage. The preheating stage refers to the stage in which the temperature of the water in the inner tank first decreases and then increases after the washing machine injects hot water into the inner tank, and the actual heating stage refers to the stage in which the temperature of the water in the inner tank continues to increase (i.e., steadily increases). For example, Figure 5 As shown, Figure 5It is a temperature curve of the water in the inner tank after the washing machine injects hot water into the inner tank. Among them, T0 represents the water inlet stage, T1 represents the preheating time period, and T2 represents the actual heating stage.

[0115] Therefore, the washing equipment can be specifically Figure 6 Steps S601 to S604 shown in the figure obtain a fourth temperature value of water after the second preset time period, as detailed below:

[0116] In S601, the target water intake amount in the inner tank of the washing device is obtained.

[0117] In one implementation of this embodiment, the washing device can obtain the target water intake in the inner tank of the washing device through a server connected to the washing device by wireless or wired communication, wherein the server can be a desktop computer or a computer.

[0118] In another implementation of this embodiment, after the washing machine completes the water filling operation into the inner tank, it can read the water level value fed back by the water level detection device located inside the inner tank of the washing machine, and determine the target water filling amount in the inner tank according to the water level value. The water level detection device can be a water level meter.

[0119] In S602, based on a plurality of stored historical heating records, a plurality of historical heating times corresponding to the target water intake in the actual heating stage are obtained.

[0120] In this embodiment, the washing machine can record the historical water intake volume each time the water in the inner tank is heated and the historical heating time corresponding to the historical water intake volume in the actual heating stage.

[0121] In one embodiment of the present application, the washing machine may be pre-set with a heating phase report template. The heating phase report template is pre-configured with a plurality of preset record items. The preset record items include but are not limited to: historical water intake and historical heating time of the actual heating phase.

[0122] Based on this, the washing machine can determine multiple historical heating times corresponding to the target water intake in the time heating stage according to the historical water intake recorded in the above heating stage report template and the historical heating time of the actual heating stage.

[0123] In S603, the heating reference time of the actual heating stage is calculated according to the multiple historical heating times.

[0124] In this embodiment, after obtaining multiple historical heating times corresponding to the target water intake, in order to improve the accuracy of calculating the heating reference time in the actual heating stage, the washing equipment can determine the time average of the multiple historical heating times as the heating reference value of the target water intake in the actual heating stage.

[0125] After obtaining the heating reference value, the washing device may compare the heating reference value with the third preset time period.

[0126] In S604, if it is detected that the second preset heating time period is equal to the heating reference time, a fourth temperature value of the water after the second preset heating time period is acquired.

[0127] In this embodiment, when the washing device detects that the second preset heating time period is equal to the above-mentioned heating reference time, it indicates that the second preset heating time period is the stage in which the temperature of the water in the inner tank steadily rises. Therefore, the washing device can obtain the fourth temperature value of the water after the second preset heating time period.

[0128] In S302, if it is detected that the difference between the fourth temperature value and the initial temperature value is greater than or equal to the first temperature threshold, the response signal is generated.

[0129] In this embodiment, when the washing device detects that the difference between the fourth temperature value of the water after the second preset heating time period and the initial temperature value is greater than the first temperature threshold, it indicates that the temperature of the water is in a stable rising stage, that is, the heating component is normal and the heating stage is also in a normal state. Therefore, the washing device can generate a response signal indicating that the heating stage is normal.

[0130] From the above, it can be seen that in the heating detection method for a washing device provided in this embodiment, when it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, the first temperature value can be determined to be the initial temperature value, and after determining the lowest temperature (i.e., the initial temperature value), in order to obtain the temperature value of water in the heating stable stage, the fourth temperature value of the water after the second preset heating time period can be obtained, and the difference between the fourth temperature value and the initial temperature value can be compared with the second preset threshold value, and when it is detected that the second difference is greater than the first temperature threshold value, a response signal is generated, thereby further improving the detection accuracy.

[0131] 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 application.

[0132] Corresponding to the heating detection method for a washing device described in the above embodiment, Figure 7The structure block diagram of a heating detection device for washing equipment provided by an embodiment of the present application is shown. For the convenience of explanation, only the part related to the embodiment of the present application is shown. Figure 7 The heating detection device 700 of the washing equipment includes: a first acquisition unit 71, a second acquisition unit 72, a collection unit 73 and a first generation unit 74. Among them:

[0133] The first acquisition unit 71 is used to acquire a first temperature value of the water in the inner tank when it is detected that the inner tank of the washing device is in a heating stage.

[0134] The second acquisition unit 72 is used to acquire a second temperature value set of the water within a first preset heating time period; the start time of the first preset heating time period is the next time to acquire the first temperature value.

[0135] The collection unit 73 is used to determine that the first temperature value is the initial temperature value if it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, and collect multiple third temperature values ​​after the initial temperature value at a preset first time interval.

[0136] The first generating unit 74 is used to generate a response signal if it is detected that the difference between any of the third temperature values ​​and the reference temperature value obtained during the acquisition process is greater than or equal to the temperature threshold; the response signal indicates that the heating stage is normal.

[0137] In one embodiment of the present application, the reference temperature value is the initial temperature value, or another temperature value whose collection time is after the collection time of the initial temperature value and different from any of the third temperature values; the temperature threshold is determined based on the difference between the collection time of any of the third temperature values ​​and the collection time of the reference temperature value.

[0138] In one embodiment of the present application, the heating detection device 700 of the washing equipment further includes: an updating unit and a returning unit.

[0139] The updating unit is configured to update the first temperature value based on the target temperature value if it is detected that there is a target temperature value smaller than the first temperature value in the second temperature value set, and to update the first preset heating time period according to the target temperature value.

[0140] The return unit is used to return to the operation of obtaining the second temperature value set of the water within the first preset heating time period according to the updated first temperature value and the updated first preset heating time period, until each second temperature value in the re-acquired second temperature value set is greater than the updated first temperature value.

[0141] In one embodiment of the present application, the updating unit is specifically used to: if it is detected that there are multiple second temperature values ​​smaller than the first temperature value in the second temperature value set, determine the smallest temperature value among the multiple second temperature values ​​as the target temperature value, and update the first temperature value based on the target temperature value, and update the first preset heating time period according to the target temperature value.

[0142] In one embodiment of the present application, the acquisition unit 73 specifically includes: a third acquisition unit, and correspondingly, the first generation unit 74 specifically includes: a second generation unit.

[0143] The third acquisition unit is used to determine that the first temperature value is an initial temperature value if it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, and to acquire a fourth temperature value of the water after a second preset heating time period.

[0144] The second generating unit is configured to generate the response signal if it is detected that the difference between the fourth temperature value and the initial temperature value is greater than or equal to the first temperature threshold.

[0145] In one embodiment of the present application, the third acquisition unit specifically includes: a fourth acquisition unit, a construction unit and a fifth acquisition unit. Among them:

[0146] The fourth acquisition unit is used to acquire a plurality of fifth temperature values ​​of the water within the second preset heating time period at preset second time intervals.

[0147] The constructing unit is used to construct a temperature curve graph according to the multiple fifth temperature values ​​and the collection moments respectively corresponding to the multiple fifth temperature values.

[0148] The fifth acquisition unit is used to acquire a fourth temperature value of the water after the second preset heating time period if it is detected that the slope of the temperature curve is greater than or equal to a slope threshold.

[0149] In one embodiment of the present application, the heating stage includes a preheating stage and an actual heating stage; the third acquisition unit specifically includes: a sixth acquisition unit, a seventh acquisition unit, a calculation unit and an eighth acquisition unit. Among them:

[0150] The sixth acquisition unit is used to acquire the target water intake volume in the inner tank of the washing device.

[0151] The seventh acquisition unit is used to acquire a plurality of historical heating times corresponding to the target water intake in the actual heating stage based on a plurality of stored historical heating records.

[0152] The calculation unit is used to calculate the heating reference time of the actual heating stage according to the multiple historical heating times.

[0153] The eighth acquisition unit is used to acquire a fourth temperature value of the water after the second preset heating time period if it is detected that the second preset heating time period is equal to the heating reference time.

[0154] From the above, it can be seen that in a heating detection device for a washing device provided by an embodiment of the present application, since the water that usually enters the inner tank of the washing device is hot water (higher than normal temperature), and the temperature of the inner tank at this time is normal temperature, that is, the temperature of the inner tank at this time is lower than the temperature of the hot water, and at the same time, since the inner tank absorbs heat, although the water is being heated, the heating speed is far slower than the heat dissipation speed, so there is a time period in which the temperature first drops and then rises during the heating stage. Therefore, when it is detected that the inner tank of the washing device is in the heating stage, the first temperature value of the water in the inner tank can be obtained first; then, a second temperature value set of the water is obtained within a first preset heating time period, and the start time of the first preset heating time period is the next time to obtain the first temperature value; and when it is detected that each second temperature value in the second temperature value set is greater than the first temperature value, it indicates that the first temperature value is the lowest temperature, and therefore, it can be determined that the first temperature value is the initial temperature value, and at this time, multiple third temperature values ​​after the time of the initial temperature value can be collected at a preset first time interval, and when it is detected that the difference between any third temperature value and the reference temperature value obtained during the collection process is greater than or equal to the temperature threshold, a response signal indicating that the heating stage is normal can be generated. The heating detection method for the washing equipment provided in the embodiment of the present application will start to detect whether the heating stage of the washing equipment is normal only after the lowest temperature (ie, the initial temperature) is determined, thereby improving the detection accuracy.
