Background technique

Current clothing processing equipment, such as washing machines, basically have a power-down memory function. Due to a power outage or the user accidentally unplugging the power cord, the power is lost. After the power is turned on again or the power cord is plugged in, the existing technology uses power-down memory to process the clothes. The control method for re-operation of the processing equipment is to control the washing machine according to the laundry operation status memorized before the power outage after detecting that the power is turned on (power on/off). However, for some long-term power outages, if the power outage is too long and the washing water is stored for a long time, it is not appropriate to continue to use such washing water for washing. (For example: unhygienic breeding of bacteria), or if the clothes in the bucket are dehydrated during a power outage, storing the clothes in the bucket for a long time will also cause the clothes to have odor, unsanitary or wrinkles. Therefore, existing technical solutions for controlling the operation of clothing processing equipment based on power-off memory can easily lead to poor equipment operation and processing effects, affecting equipment processing performance, poor clothing processing quality, and poor user experience.

Therefore, there is a need in this field for a solution that uses fewer components, is simple and easy to implement, and is low-cost, based on the memory control of the working status of the clothing processing equipment after power-off and re-powering, to avoid the existing technology of storing clothes for a long time and then controlling them. Defects such as odor, unhygienic or wrinkles that result in reduced clothing processing quality and performance (such as odor, unhygienic or wrinkles) caused by continuing the working status before the power outage are improved to improve the intelligence and practicality of the clothing processing equipment to better meet user needs and bring for a better user experience.

Current clothing processing equipment, such as washing machines, basically have a power-off memory function. Due to a power outage or the user accidentally unplugging the power cord, the power is lost/outageed. After the power is turned on again or the power cord is plugged in, the existing technology uses the power-off memory function. The control method of memory to re-operate the laundry processing equipment is to control the washing machine according to the laundry operation status memorized before the power outage after detecting that the power is turned on (power on/off). The laundry operation state will continue to continue the laundry operation process before the power outage; however, for a longer power outage, if the power outage time is too long, it is easy to breed bacteria and unhygienic when the washing water is stored for a long time, and then continue to use such water. Improper washing, or if the clothes in the bucket are dehydrated when the power is out, storing the clothes in the bucket for a long time will cause the clothes to have odor or wrinkles, resulting in poor quality of clothes processing, affecting normal equipment processing performance and effect, poor user experience, etc. defect.

An example of the control method based on power-down memory of the present invention at least includes: detecting the power-down memory stored by the clothes processing equipment when the power is cut off, and based on the specific temperature of the clothes treatment equipment when the power is cut off recorded in the power-down memory and the The temperature difference is calculated from the specific temperature detected when the equipment is powered on again, and the operating state of the clothing treatment equipment is controlled based on the temperature difference. For example, whether to directly continue the operating state of the clothing treatment equipment before the power outage, or to change the clothing treatment equipment The device operates in the operating state before power outage. Control operations in a manner that continues or changes the operating state, including but not limited to: restarting the operating program of the operating state of the laundry treatment equipment at the time of power outage recorded in the power-off memory, or first running the previous operating state of the operating state , or, add the running state and then enter the running state after completion, or directly continue the running state when the power is off, etc. The specific temperature includes: the water temperature of the clothes processing equipment or the motor temperature of the clothes processing equipment.

Referring to FIG. 1 , FIG. 1 is a main flow chart of an embodiment of a control method based on power-off memory according to the present invention.

Step S110: When the clothes treatment equipment is powered on again, the power-down memory stored when the clothes treatment equipment was powered off is detected, and the specific temperature of the clothes treatment equipment recorded when the power was cut off is obtained.

Among them, clothing processing equipment such as: washing machine, dryer, dewatering/drying machine, etc. The specific temperature of the laundry treatment equipment, for example: water temperature, if it is a washing machine, it can be the water temperature of the bucket, or the motor temperature.

In one embodiment, a washing machine is taken as an example to illustrate the solution of the present invention. After the clothes processing equipment, such as a washing machine, is powered on/connected to the power supply, it can be selected or set according to the user's mode of the equipment, and the clothes processing will be run according to the specified process/program of the corresponding mode to process the clothes. The computer board of clothing processing equipment such as a washing machine has a storage unit, which can update the stored and recorded current status of the washing machine from time to time during the operation of the washing machine (for example, the detected time, the operating status corresponding to the time, mode, water temperature, and/or motor temperature). etc). The operating status of the washing machine during a power outage is also recorded during the power outage.

For example, if the user selects "quick rinse mode" and is already in the rinsing state, and a sudden power outage causes the washing machine to lose power, the computer board's storage unit can record the "rinsing state" that was running when the power was cut off.

Furthermore, the record may also include the power outage time corresponding to the operating state, the water temperature sensor that detects the water temperature in the washing machine barrel during the power outage, and/or the motor temperature sensor installed inside the motor that detects the temperature of the washing machine motor. The water temperature during power outage/or the motor temperature during power outage, etc. are collected together and stored accordingly. The stored information during power outage as a record includes: mode, operating status, time, water temperature during power outage/or motor temperature during power outage, etc., as a power outage memory, specifically, it can be stored in the memory of the computer board. unit for backup.

In one embodiment, when the power is cut off, the power is turned on again to power up the clothes processing equipment, for example: a call comes in, or a loose plug is plugged in again, etc., that is, the equipment is powered on again, and the power-down information stored in the equipment is updated. Memory is tested. For example, when the washing machine is powered on again, the computer board controls to detect the power-off memory stored in the storage unit after the computer board is powered on, and obtains various information in the power-off memory. Preferably, various information recorded during the power-off are recorded during the power-off. .

Furthermore, based on the information stored in the power-off memory when the power is off, the specific temperature of the clothes processing equipment when the power is off is detected, such as water temperature or motor temperature.

For another example: you can first determine whether there is a heating treatment program in the operating program corresponding to the operating state when the power is off, or whether the heating function is required in this operating state. If so, the water temperature of the clothes treatment equipment can be detected, otherwise the motor temperature of the clothes treatment equipment can be detected.

Further, the water temperature or motor temperature detected in the power-off information recorded in the power-off memory is read as the specific temperature of the device when the power is off.

Step S120: When the clothes processing equipment is powered on again, a specific temperature when the equipment is powered on again corresponding to a specific temperature when the equipment is powered off is detected to calculate a temperature difference.

In one embodiment, the detected specific temperature when the device is powered off is, for example, the aforementioned water temperature or motor temperature when the device is powered off. The specific temperature of the device when power is re-energized, for example, the water temperature when the device is re-power-on is detected corresponding to the water temperature when power is off, and the motor temperature when the device is re-power-on is detected corresponding to the motor temperature when power is off.

In one embodiment, based on the information in the power-off detection memory, the operating status during the power outage, the power outage time of the clothes processing equipment corresponding to the operating status, the water temperature during the power outage/or the motor temperature during the power outage, etc. are obtained by first Detect the operating state to confirm whether there is heating processing during the execution of the operating state.

For example: there is a rinsing status in the power-off memory, which can further include the corresponding "powerful heavy laundry washing" mode. In this mode, the water temperature needs to be heated to 30°C, 40°C or 50°C, etc. The water temperature is usually heated, and the same is true for running the rinse. Run at heated water temperature. Among them, if there is a heating process, it means that the water temperature in the washing machine bucket needs to be heated in the rinsing state. The water temperature recorded during the power outage can be used as the specific temperature during the power outage. At the same time, due to the operation recorded in the power outage memory, The status indicates that the operating status of the device when it is powered off requires heating. When the device is powered back on, the water temperature when powered back on can be detected as the specific temperature of the device to calculate the temperature difference. Furthermore, a water temperature sensor can be used to detect the water temperature in the washing machine bucket.

Another example: there is a rinsing state in the power-off memory, which may further include a "quick washing of silk and woolen clothes" mode; or there is a dehydration state in the power-off memory. In this mode, there is no need to heat the water temperature for rinsing (heating may cause damage to the clothes) or there is no need to heat the water in the dehydration state. There is no heating process. The water temperature when the power is turned on again is actually the same as the water temperature when the power is turned off. In this way, there is no need to heat the water for rinsing (heating may cause damage to the clothes). When performing the heating function, it is necessary to detect the motor temperature when the current clothes processing equipment is powered on again, for example, use a motor temperature sensor set in the motor to detect the current motor temperature of the equipment motor.

For another example, it is enough to read the specific temperature recorded in the power-off memory according to the above-mentioned method, and detect the specific temperature when the device is powered on again. For example, as mentioned above, you can first determine whether the operating status during a power outage requires heating processing. If so, the water temperature when the power is off is read. Then based on the water temperature, the water temperature of the device when the power is turned on can be determined. If If not required, what is read is the motor temperature at the time of assertion. Then based on the motor temperature, the motor temperature of the device when the device is powered on again can be determined.

In one embodiment, taking a washing machine as an example, if it is detected that the washing machine has a heating function/process/program in the operating state before power outage/power outage, the power outage detected from the recorded power outage memory information will be used. The difference (absolute value) between the water temperature in the barrel when the washing machine was running before the power was turned off and the water temperature in the barrel detected after the washing machine was powered on again is calculated. The temperature deviation is calculated to obtain the temperature difference of the water temperature in the barrel. value; or, if it is detected that the operating state of the washing machine before the power outage does not have heating processing, the motor temperature value of the washing machine before the power outage will be detected from the recorded power outage memory information, Make the difference (absolute value) with the motor temperature value after the washing machine is powered on again, calculate the temperature deviation, and obtain the temperature difference value of the motor temperature.

Furthermore, the washing modes of the washing machine include: single rinse, single dehydration, strong washing of heavy clothes, gentle washing of silk and wool fabrics, quick washing, standard washing, etc. Further, the operating status of the washing machine is such as: soaking, adding water, heating, washing, dehydration, rinsing, etc.

Among them, according to the actual mode and operating program of the actual clothing processing equipment, various clothing processing performances of the equipment, etc., the user can be provided with preset or selection, that is, the mode set by the user can be based on the various modes provided by the actual clothing processing equipment. Make a selection or setting.

In one embodiment, a washing machine is used as an example of the clothes processing equipment. If the washing machine is in the rinsing operation state in the strong washing mode for heavy clothes before the power is cut off, and has a heating treatment program, the power outage memory detected and recorded when the washing machine is powered off will be stored in the power outage memory. When the power is turned on, the water temperature, that is, the water temperature in the barrel is 30°C. When the washing machine is powered on again, heating processing is determined based on the operating status during the power outage, the water temperature in the power-off memory is read, and the water temperature sensor in the washing machine barrel is controlled to detect When the power is turned on again, the water temperature in the bucket is 22°C. Then, subtract the 22°C from the 30°C, and the absolute value is used as the temperature difference of the water temperature. In this example, the temperature difference of the water temperature in the bucket is 8°C; if the washing machine shuts down. The washing machine is in dehydration operation before powering on, and does not have heating processing. In the power-down memory detected and recorded when the washing machine is powered off, the motor temperature is 40°C. When the washing machine is powered on again, it is determined based on the operating status during the power-off that no heating is required. Process, read out the motor temperature in the power-off memory, and control the motor temperature sensor set in the washing machine motor to detect that the motor temperature is 32°C when power is re-energized. Then, subtract the 32°C of the motor from the 40°C, and the absolute The value is used as the temperature difference of the motor. In this example, the temperature difference of the motor is 8℃.

Step S130: According to the temperature difference, control the operating state of the clothes treatment equipment when it is powered on again.

Specifically, according to the temperature difference, it is compared with a preset threshold to control the operating state of the clothes treatment equipment after it is powered on again. For example: control whether to directly continue the operating state of the laundry treatment equipment before the power was cut off, or to change the operating status of the laundry treatment equipment before the power was cut off. Control operations in a manner that continues or changes the operating state, including but not limited to: restarting the operating program of the operating state of the laundry treatment equipment at the time of power outage recorded in the power-off memory, or first running the previous operating state of the operating state , or, add the running state and then enter the running state after completion, or directly continue the running state when the power is off, etc.

The preset threshold is a preset temperature threshold. In one embodiment, the temperature difference is compared with a preset threshold. If the temperature difference is greater than or equal to (greater than or equal to, ≥ or not less than) the preset threshold, it indicates that the device continues to operate after power off. The time is longer, and if the temperature difference is less than (<) the preset threshold, it indicates that the device lasts for a short time after being powered off. For example, the preset threshold is 9°C, and the temperature difference of 8°C in the previous example is less than the threshold; another example is the preset threshold of 5°C, and the temperature difference of 8°C in the previous example is greater than the threshold.

Furthermore, the preset thresholds can also be set in stages based on how long the device is running. In one implementation, the preset threshold is set in stages for the running time of the device. For example: when the user selects the standard washing mode, the clothing processing equipment needs to work or run for 45 minutes. The preset threshold can be set to 10°C in the first half of the 20-minute working period and before, and in the second half of the 20-minute period. The preset threshold can be set to 20°C, etc.

Specifically, if the device works or runs for 1 minute when the power is off, that is, it has just started running, the information at the time of the power outage can be recorded in the power-off memory of the device. After the device is powered on again, the temperature difference will be recorded. Compare with the set threshold value of 10°C in the first half of the stage; when the power was cut off, the device worked or ran for 35 minutes, that is, the work or operation is about to end, which can correspond to the power-off information recorded in the device's power-down memory. , after the device is powered on again, the temperature difference is compared with the set threshold value in the second half of the stage, such as 20°C.

Furthermore, after comparison, if the temperature difference is less than the preset threshold, it means that the power outage time is short, and the device is controlled to continue to operate in the operating state when the power is off, for example, the temperature difference is 8°C, and the power outage memory records the operation during the power outage. In the first half of the stage, compared with the preset threshold of 10°C in this stage, the power outage time is very short and the equipment continues to operate. The washing machine, for example, continues to operate in the rinsing state before the power outage; otherwise, it means that the power outage time is too long, such as the temperature The difference is 25°C, and the power-down memory record runs to the second half of the stage when the power is cut off. Compared with the preset threshold of 20°C for this stage, the power-off time is longer, and the equipment restarts from the initial time of this operating state. A washing machine is an example. , change the water (the water used in previous rinsing is released and new clean water is added), and the rinsing state is restarted.

Another example: washing machine, dehydration status, power outage, power outage memory includes: power outage time, dehydration status during power outage, water temperature and motor temperature, and further includes the washing machine washing mode selected or set by the user, such as standard mode, etc. Among them, the dehydration state is the second half of the standard mode selected by the user. The dehydration state does not require heating treatment. In this way, the difference between the detected motor temperature and the motor temperature during power outage in the power-down memory is used. The absolute value is the temperature difference and the second half. The stage is compared with the preset threshold value of 20°C. If it is greater than or equal to 20°C, the washing machine is controlled to start from the previous state of the dehydration state in this mode, such as the rinsing state, and then dehydrate after completing the rinsing.

It should be pointed out that although the various steps are described in a specific order in the above embodiments, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in other sequences, and these changes are within the scope of the present invention.

Referring below to Figure 2, a structural block diagram of an embodiment of a control system based on power-off memory of the present invention is shown. The system includes at least:

The detection module 210 is configured to detect the power-down memory stored when the clothes treatment equipment is powered off when the clothes treatment equipment is powered on again, and obtain the specific temperature of the clothes treatment equipment recorded when the power is cut off.

Among them, clothing processing equipment such as: washing machine, dryer, dewatering/drying machine, etc. The specific temperature of the laundry treatment equipment, for example: water temperature, if it is a washing machine, it can be the water temperature of the bucket, or the motor temperature.

In one embodiment, a washing machine is taken as an example to illustrate the solution of the present invention. After the clothes processing equipment, such as a washing machine, is powered on/connected to the power supply, it can be selected or set according to the user's mode of the equipment, and the clothes processing will be run according to the specified process/program of the corresponding mode to process the clothes. The computer board of clothing processing equipment such as a washing machine has a storage unit, which can update the stored and recorded current status of the washing machine from time to time during the operation of the washing machine (for example, the detected time, the operating status corresponding to the time, mode, water temperature, and/or motor temperature). etc). The operating status of the washing machine during a power outage is also recorded during the power outage.

For example, if the user selects "quick rinse mode" and is already in the rinsing state, and a sudden power outage causes the washing machine to lose power, the computer board's storage unit can record the "rinsing state" that was running when the power was cut off.

Furthermore, the record may also include the power outage time corresponding to the operating state, the water temperature sensor that detects the water temperature in the washing machine barrel during the power outage, and/or the motor temperature sensor installed inside the motor that detects the temperature of the washing machine motor. The water temperature during power outage/or the motor temperature during power outage, etc. are collected together and stored accordingly. The stored information during power outage as a record includes: mode, operating status, time, water temperature during power outage/or motor temperature during power outage, etc., as a power outage memory, specifically, it can be stored in the memory of the computer board. unit for backup.

In one embodiment, when the power is cut off, the power is turned on again to power up the clothes processing equipment, for example: a call comes in, or a loose plug is plugged in again, etc., that is, the equipment is powered on again, and the power-down information stored in the equipment is updated. Memory is tested. For example, when the washing machine is powered on again, the computer board controls to detect the power-off memory stored in the storage unit after the computer board is powered on, and obtains various information in the power-off memory. Preferably, various information recorded during the power-off are recorded during the power-off. .

Furthermore, based on the information stored in the power-off memory when the power is off, the specific temperature of the clothes processing equipment when the power is off is detected, such as water temperature or motor temperature.

For another example: you can first determine whether there is a heating treatment program in the operating program corresponding to the operating state when the power is off, or whether the heating function is required in this operating state. If so, the water temperature of the clothes treatment equipment can be detected, otherwise the motor temperature of the clothes treatment equipment can be detected.

Further, the water temperature or motor temperature detected in the power-off information recorded in the power-off memory is read as the specific temperature of the device when the power is off.

The calculation module 220 is configured to detect a specific temperature when the equipment is powered on again, corresponding to a specific temperature when the equipment is powered off, to calculate a temperature difference when the laundry treatment equipment is powered on again.

In one embodiment, the detected specific temperature when the device is powered off is, for example, the aforementioned water temperature or motor temperature when the device is powered off. The specific temperature of the device when power is re-energized, for example, the water temperature when the device is re-power-on is detected corresponding to the water temperature when power is off, and the motor temperature when the device is re-power-on is detected corresponding to the motor temperature when power is off.

In one embodiment, based on the information in the power-off detection memory, the operating status during the power outage, the power outage time of the clothes processing equipment corresponding to the operating status, the water temperature during the power outage/or the motor temperature during the power outage, etc. are obtained by first Detect the operating state to confirm whether there is heating processing during the execution of the operating state.

For example: there is a rinsing status in the power-off memory, which can further include the corresponding "powerful heavy laundry washing" mode. In this mode, the water temperature needs to be heated to 30°C, 40°C or 50°C, etc. The water temperature is usually heated, and the same is true for running the rinse. Run at heated water temperature. Among them, if there is a heating process, it means that the water temperature in the washing machine bucket needs to be heated in the rinsing state. The water temperature recorded during the power outage can be used as the specific temperature during the power outage. At the same time, due to the operation recorded in the power outage memory, The status indicates that the operating status of the device when it is powered off requires heating. When the device is powered back on, the water temperature when powered back on can be detected as the specific temperature of the device to calculate the temperature difference. Furthermore, a water temperature sensor can be used to detect the water temperature in the washing machine bucket.

Another example: there is a rinsing state in the power-off memory, which may further include a "quick washing of silk and woolen clothes" mode; or there is a dehydration state in the power-off memory. In this mode, there is no need to heat the water temperature for rinsing (heating may cause damage to the clothes) or there is no need to heat the water in the dehydration state. There is no heating process. The water temperature when the power is turned on again is actually the same as the water temperature when the power is turned off. In this way, there is no need to heat the water for rinsing (heating may cause damage to the clothes). When performing the heating function, it is necessary to detect the motor temperature when the current clothes processing equipment is powered on again, for example, use a motor temperature sensor set in the motor to detect the current motor temperature of the equipment motor.

For another example, based on the aforementioned reading of the specific temperature recorded in the power-off memory, it is enough to detect the specific temperature when the device is powered on again. For example, as mentioned above, you can first determine whether the operating status during a power outage requires heating processing. If so, the water temperature when the power is off is read. Then based on the water temperature, the water temperature of the device when the power is turned on can be determined. If If not required, what is read is the motor temperature at the time of assertion. Then based on the motor temperature, the motor temperature of the device when the device is powered on again can be determined.

In one embodiment, taking a washing machine as an example, if it is detected that the washing machine has a heating function/process/program in the operating state before power outage/power outage, the power outage detected from the recorded power outage memory information will be used. The difference (absolute value) between the water temperature in the barrel when the washing machine was running before the power was turned off and the water temperature in the barrel detected after the washing machine was powered on again is calculated. The temperature deviation is calculated to obtain the temperature difference of the water temperature in the barrel. value; or, if it is detected that the operating state of the washing machine before the power outage does not have heating processing, the motor temperature value of the washing machine before the power outage will be detected from the recorded power outage memory information, Make the difference (absolute value) with the motor temperature value after the washing machine is powered on again, calculate the temperature deviation, and obtain the temperature difference value of the motor temperature.

Furthermore, the washing modes of the washing machine include: single rinse, single dehydration, strong washing of heavy clothes, gentle washing of silk and wool fabrics, quick washing, standard washing, etc. Further, the operating status of the washing machine is such as: soaking, adding water, heating, washing, dehydration, rinsing, etc.

Among them, according to the actual mode and operating program of the actual clothing processing equipment, various clothing processing performances of the equipment, etc., the user can be provided with preset or selection, that is, the mode set by the user can be based on the various modes provided by the actual clothing processing equipment. Make a selection or setting.

In one embodiment, a washing machine is used as an example of the clothes processing equipment. If the washing machine is in the rinsing operation state in the strong washing mode for heavy clothes before the power is cut off, and has a heating treatment program, the power outage memory detected and recorded when the washing machine is powered off will be stored in the power outage memory. When the power is turned on, the water temperature, that is, the water temperature in the barrel is 30°C. When the washing machine is powered on again, heating processing is determined based on the operating status during the power outage, the water temperature in the power-off memory is read, and the water temperature sensor in the washing machine barrel is controlled to detect When the power is turned on again, the water temperature in the bucket is 22°C. Then, subtract the 22°C from the 30°C, and the absolute value is used as the temperature difference of the water temperature. In this example, the temperature difference of the water temperature in the bucket is 8°C; if the washing machine shuts down. The washing machine is in dehydration operation before powering on, and does not have heating processing. In the power-down memory detected and recorded when the washing machine is powered off, the motor temperature is 40°C. When the washing machine is powered on again, it is determined based on the operating status during the power-off that no heating is required. Process, read out the motor temperature in the power-off memory, and control the motor temperature sensor set in the washing machine motor to detect that the motor temperature is 32°C when power is re-energized. Then, subtract the 32°C of the motor from the 40°C, and the absolute The value is used as the temperature difference of the motor. In this example, the temperature difference of the motor is 8℃.

The control module 230 is used to control the re-powering operation state of the laundry treatment equipment according to the temperature difference.

Specifically, according to the temperature difference, it is compared with a preset threshold to control the operating state of the clothes treatment equipment after it is powered on again. For example: control whether to directly continue the operating state of the laundry treatment equipment before the power was cut off, or to change the operating status of the laundry treatment equipment before the power was cut off. Control operations in a manner that continues or changes the operating state, including but not limited to: restarting the operating program of the operating state of the laundry treatment equipment at the time of power outage recorded in the power-off memory, or first running the previous operating state of the operating state , or, add the running state and then enter the running state after completion, or directly continue the running state when the power is off, etc.

The preset threshold is a preset temperature threshold. In one embodiment, the temperature difference is compared with a preset threshold. If the temperature difference is greater than or equal to (greater than or equal to, ≥ or not less than) the preset threshold, it indicates that the device continues to operate after power off. The time is longer, and if the temperature difference is less than (<) the preset threshold, it indicates that the device lasts for a short time after being powered off. For example, the preset threshold is 9°C, and the temperature difference of 8°C in the previous example is less than the threshold; another example is the preset threshold of 5°C, and the temperature difference of 8°C in the previous example is greater than the threshold.

Furthermore, the preset thresholds can also be set in stages based on how long the device is running. In one implementation, the preset threshold is set in stages for the running time of the device. For example: when the user selects the standard washing mode, the clothing processing equipment needs to work or run for 45 minutes. The preset threshold can be set to 10°C in the first half of the 20-minute working period and before, and in the second half of the 20-minute period. The preset threshold can be set to 20°C, etc.

Specifically, if the device works or runs for 1 minute when the power is off, that is, it has just started running, the information at the time of the power outage can be recorded in the power-off memory of the device. After the device is powered on again, the temperature difference will be recorded. Compare with the set threshold value of 10°C in the first half of the stage; when the power was cut off, the device worked or ran for 35 minutes, that is, the work or operation is about to end, which can correspond to the power-off information recorded in the device's power-down memory. , after the device is powered on again, the temperature difference is compared with the set threshold value in the second half of the stage, such as 20°C.

Furthermore, after comparison, if the temperature difference is less than the preset threshold, it means that the power outage time is short, and the device is controlled to continue to operate in the operating state when the power is off, for example, the temperature difference is 8°C, and the power outage memory records the operation during the power outage. In the first half of the stage, compared with the preset threshold of 10°C in this stage, the power outage time is very short and the equipment continues to operate. The washing machine, for example, continues to operate in the rinsing state before the power outage; otherwise, it means that the power outage time is too long, such as the temperature The difference is 25°C, and the power-down memory record runs to the second half of the stage when the power is cut off. Compared with the preset threshold of 20°C for this stage, the power-off time is longer, and the equipment restarts from the initial time of this operating state. A washing machine is an example. , change the water (the water used in previous rinsing is released and new clean water is added), and the rinsing state is restarted.

Another example: washing machine, dehydration status, power outage, power outage memory includes: power outage time, dehydration status during power outage, water temperature and motor temperature, and further includes the washing machine washing mode selected or set by the user, such as standard mode, etc. Among them, the dehydration state is the second half of the standard mode selected by the user. The dehydration state does not require heating treatment. In this way, the difference between the detected motor temperature and the motor temperature during power outage in the power-down memory is used. The absolute value is the temperature difference and the second half. The stage is compared with the preset threshold value of 20°C. If it is greater than or equal to 20°C, the washing machine is controlled to start from the previous state of the dehydration state in this mode, such as the rinsing state, and then dehydrate after completing the rinsing.
