The ultrasonic transducers 220 may be provided with a plurality of (for example, three), and the plurality of ultrasonic transducers 220 are arranged at intervals along the length direction of the container 210 on the lower surface of the bottom wall of the container 210, and by controlling the plurality of ultrasonic transducers 220 to work simultaneously, the ultrasonic action can be applied to the object to be treated more uniformly, thereby improving the uniformity of the treatment.

The controller 300 may be electrically connected to the ultrasonic transducer 220 for providing control signals to the ultrasonic transducer 220 to start and stop the ultrasonic transducer 220 and to adjust parameters such as power, frequency, etc. of the ultrasonic transducer 220.

Specifically, the temperature detecting means 230 may be disposed at an edge position of the lower surface of the ultrasonic transducer 220 or on a thermally conductive metal sheet outwardly led from the upper surface of the ultrasonic transducer 220, so that adverse effects of the temperature detecting means 230 on vibration of the ultrasonic transducer 220 are reduced as much as possible.
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, a temperature detection value of the ultrasonic transducer 220 is obtained.
In step S406, it is determined whether the temperature detection value of the ultrasonic transducer 220 is greater than a preset temperature reference value.
In step S408, if yes, a cooling air flow is supplied to the storage compartment 110 where the ultrasonic processing apparatus 200 is located.
According to the control method of the refrigerator 10 in the embodiment of the invention, after the ultrasonic processing device 200 is started, the temperature detection value of the ultrasonic transducer 220 is firstly obtained, then whether the temperature detection value of the ultrasonic transducer 220 is larger than the preset temperature reference value is judged, if the temperature detection value of the ultrasonic transducer 220 is larger than the preset temperature reference value, it is indicated that the temperature of the ultrasonic transducer 220 is higher at this time, the refrigerating air flow can be supplied to the storage compartment 110 where the ultrasonic processing device 200 is located, so that heat dissipation can be performed on the ultrasonic transducer 220 in time, and the temperature of the ultrasonic transducer 220 is reasonably controlled.
In the above step S404, the step of acquiring the temperature detection value of the ultrasonic transducer 220 may be: a temperature indication of the temperature detecting device 230 provided on the ultrasonic transducer 220 is acquired, and the temperature indication is taken as a temperature detection value of the ultrasonic transducer 220. Because the temperature detecting device 230 is disposed on the ultrasonic transducer 220, the temperature indication thereof can more accurately reflect the temperature of the ultrasonic transducer 220, which is beneficial to the follow-up accurate control of the temperature of the ultrasonic transducer 220.
In step S406, the preset temperature reference value may be 25℃to 30℃such as 26℃and 27℃and 28 ℃. In general, when the temperature detection value of the ultrasonic transducer 220 reaches the preset temperature reference value, it indicates that the temperature of the ultrasonic transducer 220 is already high, and it is necessary to cool the ultrasonic transducer 220 in time.
The refrigerator 10 may be a single-system refrigerator 10, and the ultrasonic processing apparatus 200 may be disposed in a refrigerating compartment of the single-system refrigerator 10. The step of supplying a flow of refrigerant gas to the storage compartment 110 in which the ultrasonic treatment device 200 is located may be: the refrigerator door of the refrigerating compartment is opened first and then the compressor of the refrigerator 10 is started.
The refrigerator 10 may also be a multi-system refrigerator 10, and the ultrasonic treatment device 200 may be disposed in a refrigerating compartment of the multi-system refrigerator 10. The step of supplying a flow of refrigerant gas to the storage compartment 110 in which the ultrasonic treatment device 200 is located may be: the solenoid valve of the multi-system refrigerator 10 is switched to the refrigerating mode of the refrigerating compartment, then the refrigerating air door of the refrigerating compartment is opened, and then the compressor of the refrigerator 10 is started.
In some alternative embodiments, a side wall or a back wall of the storage compartment 110 opposite to the container 210 of the ultrasonic processing apparatus 200 is provided with a rapid cooling air door, the air output of the rapid cooling air door is smaller than the air output of the cooling air door, and the cooling air flow can directly blow the container 210 through the rapid cooling air door. There are two ways to supply the cooling air flow, one way is to open the cooling air door to cool, and the cooling speed of this way is faster, so that the method is suitable for use under the condition that the temperature of the ultrasonic transducer 220 is higher. The other is to open the rapid cooling air door for cooling, and the cooling speed in this way is slower, so that the rapid cooling air door is suitable for being used under the condition that the temperature of the ultrasonic transducer 220 is slightly higher.
After supplying the refrigerating airflow to the storage compartment 110 where the ultrasonic processing apparatus 200 is located, it may also be determined whether the temperature of the ultrasonic transducer 220 is increased, if the temperature of the ultrasonic transducer 220 is still increased, which indicates that the heat generated by the ultrasonic transducer 220 is greater than the heat dissipation capacity, it may be further determined whether the temperature detection value of the ultrasonic transducer 220 after being increased is greater than the first temperature threshold, and when the temperature detection value after being increased is greater than the first temperature threshold, the object to be processed is at risk of being cured, and the ultrasonic transducer 220 is at risk of being damaged due to overheating, and the ultrasonic transducer 220 needs to be turned off.
Further, if the temperature of the ultrasonic transducer 220 is not increased, it may be further determined whether the temperature of the ultrasonic transducer 220 is decreased, if the temperature of the ultrasonic transducer 220 is decreased, which indicates that the heat generation amount of the ultrasonic transducer 220 is smaller than the heat dissipation amount, it may be further determined whether the temperature detection value of the ultrasonic transducer 220 after being decreased is smaller than the second temperature threshold, and when the temperature detection value after being decreased is smaller than the second temperature threshold, the operation of the ultrasonic transducer 220 is good, and at this time, the supply of the cooling air flow to the storage compartment 110 may be stopped.
Further, if the temperature of the ultrasonic transducer 220 is not reduced, it means that after the cooling air flow is supplied to the storage compartment 110, the heat generating amount and the heat dissipating amount of the ultrasonic transducer 220 are balanced, and at this time, the cooling air flow can be continuously supplied to the storage compartment 110 to maintain the cooling state of the storage compartment 110.
In the event that the ultrasonic transducer 220 is turned off because the temperature detection value is greater than the first temperature threshold value, the treatment object is not actually finished, the ultrasonic transducer 220 is in a stopped cooling state, and the storage compartment 110 is receiving the cooling air flow. Therefore, after a period of time, the temperature detection value of the ultrasonic transducer 220 may be re-acquired, and then it is determined whether the re-acquired temperature detection value is less than the second temperature threshold, and if so, the supply of the cooling air flow to the storage compartment 110 is stopped and the ultrasonic transducer 220 is restarted.
In this embodiment, the first temperature threshold may be 30℃to 35℃such as 30℃and 32℃and 35 ℃. The first temperature threshold may be understood as an upper limit value of the operating temperature of the ultrasonic transducer 220, and if the temperature of the ultrasonic transducer 220 exceeds the first temperature threshold and still continues to operate, there is a greater risk of curing the object to be treated, and the ultrasonic transducer 220 itself is also susceptible to overheating damage.
The second temperature threshold may be 20 ℃ to 25 ℃, e.g., 20 ℃, 22 ℃,25 ℃, etc. It should be noted that, the second temperature threshold should be lower than the first temperature threshold, and the difference between the second temperature threshold and the first temperature threshold should not be too large, for example, about 8 ℃, so as to ensure that the ultrasonic transducer 220 can operate relatively continuously, reduce the shutdown cooling time of the ultrasonic transducer 220, and shorten the treatment period of the object to be treated.

Step S512, determining whether the temperature detected value after the rising of the ultrasonic transducer 220 is greater than the first temperature threshold, if yes, executing step S514, and if not, returning to step S508.

In step S516, the temperature detection value of the ultrasonic transducer 220 is re-acquired.
Step S518, determining whether the re-acquired temperature detection value is smaller than the second temperature threshold, if yes, executing step S520, otherwise, returning to step S516.
