Description

Electronic device control method, controller and refrigerator Technical Field The application relates to the technical field of refrigerators, in particular to an electronic device control method, a controller and a refrigerator. Background With the progress of technology and the improvement of living standard, refrigerators have become one of the indispensable appliances of modern families. The refrigerator not only can keep food fresh and make ice, but also integrates more and more intelligent functions such as touch screen display, automatic temperature adjustment, automatic defrosting and the like, and the use experience of a user is greatly improved. However, these additional intelligent functions typically require the provision of various sensors and control modules, which mostly require continuous operation to achieve real-time sensing and control, which in turn adds to the standby power consumption of the refrigerator. Taking a proximity sensor of a refrigerator as an example, the proximity sensor has the function of sensing the proximity of a user's body, so as to control the opening of components such as a refrigerator lighting lamp, a display screen and the like, even the automatic opening of a refrigerator door and the like. Conventional proximity sensors, particularly radar-type proximity sensors, typically need to be in operation at all times in preparation for sensing a human signal. However, the time of the user approaching the refrigerator is only a small part of the day, and no person is present around the refrigerator in most of the time, and the continuous operation of the sensor is an energy waste. Studies have shown that for some intelligent refrigerators on the market, the power consumption of the proximity sensor may be about one-fourth of the total standby power consumption of the refrigerator except for refrigeration, a considerable proportion. How to reduce the power consumption of electronic devices such as a proximity sensor on the premise of ensuring the basically normal use of the electronic devices becomes a problem to be solved in the aspects of energy saving and efficiency improvement of the refrigerator. For this reason, there is still a real need for continued improvement in refrigerators with respect to control of electronics. Disclosure of Invention In view of this, it is an object of embodiments of the present application to provide an improved electronic device control method, an improved controller and an improved refrigerator, to overcome at least one of the above-mentioned drawbacks and/or other possible drawbacks not mentioned herein. According to a first aspect of the present application, there is provided an electronic device control method applied to a refrigerator having an electronic device, wherein the electronic device control method includes the steps of S101 acquiring a reference time, S300 recording user activity information of the refrigerator based on the acquired reference time, S400 analyzing and processing the user activity information to determine at least one first control period in which the refrigerator is used at a frequency lower than a first threshold, and S500 controlling the electronic device to operate at a first power lower than a set power thereof when a current time is in the first control period. Therefore, the first control time period of the electronic device is determined by acquiring the reference time record and analyzing the user activity, and the electronic device can reduce the working power in the first control time period due to low use frequency of the refrigerator, so that the continuous power consumption of the electronic device such as a proximity sensor is greatly reduced, and the energy saving of the whole refrigerator is realized. Compared with the scheme that a user is required to actively turn off the electronic device to reduce power consumption in the prior art, the embodiment of the application can automatically realize low-power-consumption operation of the electronic device on the premise of ensuring the basically normal use function of the electronic device, and does not need user intervention, thereby improving user experience. According to an alternative embodiment step S101 comprises the sub-steps of S100 of obtaining environmental data around said refrigerator S200 of deriving a corresponding time from said environmental data as said reference time. Accordingly, by estimating the corresponding time as the reference time using environmental data such as temperature, illumination intensity, or environmental sound, the reference time having high reliability can be estimated even when the refrigerator is in an offline, non-networked state. According to an alternative embodiment, sub-step S200 comprises the sub-steps of S2100 of obtaining environmental data for consecutive N sampling periods with 24 hours as one sampling period, N being an integer greater than one, S2200 of determining at least one point in time
