Fig. 4 is a schematic view of a control method of the refrigerator 10 according to an embodiment of the present invention, and referring to fig. 4, the control method includes at least the following steps S402 to S408.
Step S402, the ultrasonic processing apparatus 200 is started.
In step S404, it is determined whether the storage compartment 110 where the ultrasonic processing apparatus 200 is located satisfies the pre-cooling condition.
In step S406, if the determination result is yes, it is determined whether the compressor 120 of the refrigerator 10 is in a started state.
In step S408, if the compressor 120 is in the on state, the storage compartment 110 in which the ultrasonic processing apparatus 200 is located is cooled.
In the control method of the refrigerator 10 according to the embodiment of the present invention, after the ultrasonic processing apparatus 200 is started, it is first determined whether the storage compartment 110 in which the ultrasonic processing apparatus 200 is located meets the pre-cooling condition, if the storage compartment 110 meets the pre-cooling condition, it is further determined whether the compressor 120 of the refrigerator 10 is in a starting state, and if the storage compartment 110 meets the pre-cooling condition, and the compressor 120 is in the starting state, the storage compartment 110 in which the ultrasonic processing apparatus 200 is located is cooled. In this way, frequent start of the compressor 120 can be prevented during the ultrasonic treatment operation, thereby effectively reducing the damage degree of the compressor 120 and prolonging the service life of the compressor 120.
In step S404 above, the pre-cooling conditions may include: the temperature detection value of the storage compartment 110 is greater than a preset compartment temperature reference value. For example, in the case where the storage compartment 110 is a refrigerating compartment, if the threshold temperature of the starting point of the refrigerating compartment is 7 ℃ to 9 ℃, the reference temperature of the compartment may be 3 ℃ to 7 ℃, and the reference temperature of the compartment should be about 2 ℃ to 5 ℃ less than the threshold temperature of the starting point.
In this embodiment, a first temperature threshold, a second temperature threshold, a first temperature reference value and a second temperature reference value of the ultrasonic transducer 220 may be preset, where the first temperature threshold is a minimum working temperature of the ultrasonic transducer 220, which may be 20 ℃ to 25 ℃, the second temperature threshold is a maximum working temperature of the ultrasonic transducer 220, which may be 30 ℃ to 35 ℃, the first temperature reference value may be 20 ℃ to 25 ℃, and the second temperature reference value may be 25 ℃ to 30 ℃. The values of the first temperature threshold value, the first temperature reference value, the second temperature reference value, and the second temperature threshold value should be sequentially increased. In a typical configuration, the first temperature threshold is 20 ℃, the first temperature reference is 25 ℃, the second temperature reference is 30 ℃, and the second temperature threshold is 35 ℃.
The pre-cold condition may further comprise: the temperature detection value of the ultrasonic transducer 220 is greater than a preset first temperature reference value. When the temperature detection value of the ultrasonic transducer 220 is greater than the preset first temperature reference value, it indicates that the temperature of the ultrasonic transducer 220 has been significantly increased, and if the compressor 120 is in the start state, the storage compartment 110 where the ultrasonic processing apparatus 200 is located can be cooled down, so as to perform a certain cooling function on the ultrasonic transducer 220.
In the case that the storage compartment 110 where the ultrasonic processing apparatus 200 is located meets the pre-cooling condition, but the compressor 120 is in the off state, it can be determined whether other storage compartments 110 of the refrigerator 10 have cooling requirements, if other storage compartments 110 have cooling requirements, the compressor 120 can be started, and then the storage compartment 110 where the ultrasonic processing apparatus 200 is located and other storage compartments 110 having cooling requirements are cooled respectively. That is, when the other storage compartments 110 have a refrigeration requirement, the compressor 120 must be started, and after the compressor 120 is started, the storage compartments 110 where the ultrasonic treatment apparatus 200 is located can be refrigerated, so that the temperature rising speed of the ultrasonic transducer 220 can be delayed, and the start-stop times of the compressor 120 can be reduced in the whole ultrasonic treatment process.
Under the condition that the other storage compartments 110 of the refrigerator 10 have no refrigeration requirement, it can be determined whether the temperature detection value of the ultrasonic transducer 220 is greater than the preset second temperature reference value, if the temperature detection value of the ultrasonic transducer 220 is greater than the second temperature reference value, it is indicated that the temperature of the ultrasonic transducer 220 is already higher, and the compressor 120 must be started at this time, only the storage compartment 110 where the ultrasonic processing apparatus 200 is located is refrigerated, so as to prevent the ultrasonic transducer 220 from being overheated and damaged or to enable the surface of the object to be processed to be cured due to continuous increase of the temperature.
Since the ultrasonic transducer 220 is very easy to be damaged when working at a higher temperature, the steps of respectively refrigerating the storage compartment 110 where the ultrasonic processing apparatus 200 is located and other storage compartments 110 having refrigeration requirements may be: firstly, refrigerating the storage compartment 110 where the ultrasonic processing apparatus 200 is located, then judging whether the temperature detection value of the ultrasonic transducer 220 is smaller than the first temperature threshold, if the temperature detection value of the ultrasonic transducer 220 is smaller than the first temperature threshold, indicating that the temperature of the ultrasonic transducer 220 is lower at this time, refrigerating the storage compartment 110 can be stopped, and in turn, refrigerating other storage compartments 110 with refrigerating requirements.
Further, after determining whether the temperature detection value of the ultrasonic transducer 220 is smaller than the first temperature threshold, if the temperature detection value of the ultrasonic transducer 220 is larger than or equal to the first temperature threshold, the heat generated by the ultrasonic transducer 220 is still larger than the heat dissipation capacity in the process of refrigerating the storage compartment 110 where the ultrasonic processing apparatus 200 is located, and the temperature of the ultrasonic transducer 220 is still continuously raised, at this time, it may be further determined whether the temperature detection value of the ultrasonic transducer 220 is larger than the second temperature threshold, and if the temperature detection value of the ultrasonic transducer 220 is larger than the second temperature threshold, the ultrasonic processing apparatus 200 is immediately turned off, so that the ultrasonic transducer 220 is stopped to cool, and the ultrasonic transducer 220 is prevented from being overheated and damaged.
Further, after the ultrasonic transducer 220 is turned off, it may be determined whether the detected temperature value of the storage compartment 110 in which the ultrasonic processing apparatus 200 is located is less than a preset shutdown point temperature threshold, and if the detected temperature value is less than the shutdown point temperature threshold, it is indicated that the storage compartment 110 is cooled, and the other storage compartments 110 having the cooling requirement may be cooled to maintain the internal temperature of the other storage compartments 110.

Step S506, it is determined whether the compressor 120 of the refrigerator 10 is in a start state, if so, step S508 is executed, and if not, step S510 is executed.
In step S508, the storage compartment 110 in which the ultrasonic processing apparatus 200 is located is cooled.
Step S510 is executed to determine whether there is a cooling requirement for the other storage compartments 110 of the refrigerator 10, if yes, step S512 is executed, and if not, step S524 is executed.
