- the control method of the present invention controls the operation of the fan when the temperature in the groove 211 is less than or equal to the dew point temperature, and introduces hot air from the surrounding environment into the groove 211 to increase the temperature in the groove 211, and avoids the temperature in the groove 211.
- Condensation improves the safety and reliability of the electrical components in the groove 211, and compared with the anti-condensation methods such as heating wires and heat pipes in the groove 211, the cost is low, the process is simple, and the production cost is reduced.
- step S604 the following steps may be further included:
- the fan 190 is controlled to stop running, so as to effectively prevent condensation in the groove 211, prevent the fan 190 from starting frequently, and prolong the service life of the fan 190.
- step S604 the following steps may also be included after step S604:
- the fan 190 is immediately controlled to stop running.
- step S604 the following steps may be further included:
- the power supply module 180 If not, energize the power supply module 180 (do not provide power to the electromagnetic wave generating module 120, and the electromagnetic wave generating module 120 does not work) to generate heat, shorten the continuous working time of the fan 190, further extend the service life of the fan 190, and reduce noise .
- control method of the present invention may further include:
- the power supply module 180 is stopped to be energized to save energy and avoid overheating in the groove 211.
- control method of the present invention may further include:
- step S604 After performing step S604 for the second preset time, it is determined whether the temperature in the groove 211 is greater than or equal to the ambient temperature, so as to further prevent condensation in the groove 211 and avoid frequent activation of the fan 190.
- step S602 the following steps may be further included after step S602:
- control the fan 190 to run at the second preset speed to dissipate heat for the electromagnetic wave generating module 120 and the power supply module 180;
- step S602 determine whether anti-condensation is needed.
- the second preset speed may be greater than the first preset speed to improve heat dissipation efficiency and reduce the energy consumption and noise of the fan 190 during condensation prevention.
- the temperature of the electromagnetic wave generating module 120 can be used as the temperature in the groove 211 for judgment and control, so as to more accurately determine whether condensation will occur in the groove 211, thereby effectively preventing condensation.
- Fig. 7 is a schematic detailed flowchart of a control method for a refrigerating and freezing device 200 according to an embodiment of the present invention.
- the control method for the refrigerating and freezing device 200 of the present invention may include the following detailed steps:
- Step S702 Determine whether the electromagnetic wave generating module 120 is in a working state. If yes, go to step S718; if not, go to step S704.
- Step S704 Determine whether the temperature of the electromagnetic wave generating module 120 is less than or equal to the dew point temperature. If yes, go to step S706; if no, go back to step S702.
- Step S706 Control the fan 190 to operate at the first preset speed.
- Step S708 Determine whether step S706 has been executed for a second preset time. If yes, go to step S710; if no, go back to step S706.
- Step S710 Determine whether the temperature of the electromagnetic wave generating module 120 is greater than or equal to the ambient temperature. If yes, go to step S714; if not, go to step S712.
- Step S712 The power supply module 180 is powered on.
- Step S714 Stop the power supply module 180 from being powered on. Step S716 is executed.
- Step S716 After the first preset time, the fan 190 is controlled to stop running. Return to step S702.
- Step S718 Control the fan 190 to operate at the second preset speed. Return to step S702.
- step S718 if the electromagnetic wave generating module 120 starts to work during the execution of step S704 to step S716, it will immediately jump to step S718.
- control method of the present invention is also applicable to other electrical devices arranged in the groove 211.
