A method for smart refrigerators to judge day and night based on user habits

Abstract

A method for enabling an intelligent refrigerator to judge daytime and night according to the use habit of a user comprises the following steps that A, a day is divided into 24 hours, and the busy hours and the idle hours are judged out; B, the idle time section is found and judged to be the night time section of the day, the remaining time section is the daytime time section, and then the daytime / night time sections of the day are obtained through statistics; C, statistics and collection of relevant data are continuously conducted for 7 days, and the daytime / night time sections of the user are obtained through statistics; D, according to the information of the daytime / night time sections of the user, the rpm of a compressor and / or a draught fan is controlled; E, the actual daytime / night time sections are obtained through statistics and compared with the daytime / night time sections of the user everyday in days to come, and whether the actual daytime / night time sections are identical with the daytime / night time sections of the user is judged; and F, if it is judged that the actual daytime / night time sections are continuously different from the daytime / night time sections of the user for four days, the stored daytime / night time sections of the user are cleared, and the collection stage in the step A is executed again. The method for enabling the intelligent refrigerator to judge daytime and night according to the use habit of the user has the characteristics that the daytime and the night are accurately judged, cost is low, the performance is reliable, the electricity consumption is effectively reduced, and nose is effectively lowered.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a method for judging day and night according to user usage habits of a smart refrigerator. Background technique [0002] At present, the common frequency conversion refrigerators on the market adjust the speed of the compressor according to the temperature difference between the ambient temperature, the temperature in the box and the set temperature, so as to achieve the purpose of reducing energy consumption. When users use the refrigerator during the daytime, they often hope that the refrigerator can be cooled as soon as possible. However, during the nighttime period, the user uses the refrigerator for less time, and the temperature inside the box does not change much. The user does not have high requirements for the cooling speed. The high operating speed and start-up rate will help to further reduce energy consumption. At the same time, because the compressor actively reduces the speed at ni...

Chinese Patent Document No. CN1216263C disclosed a method for reducing nighttime noise of a refrigerator and its light-controlled refrigerator on August 24, 2005. Brightness threshold, judging that one side of the threshold is daytime, and the other side of the threshold is nighttime; however, it turns out that day and night cannot be accurately distinguished according to the brightness. The refrigerator actually collects the brightness of the indoor light, and the brightness of the light is the same as the actual daytime There is no necessary connection between the / night time period and the user's usage habits, resulting in misjudgment of the daytime / night time period, which affects the user experience; in view of the fact that smart refrigerators are generally equipped with wifi networking functions, smart refrigerators that obtain time through wifi modules appear on the market. Refrigerators, it is a more direct method to judge the time of day / night according to the time, but this judgment method is not suitable for refrigerators without wifi function, nor is it suitable for areas without wifi signal coverage; The night method needs to be further improved
