Problems solved by technology

The smart refrigerator involved in Patent 5 is equipped with a wifi module and an MCU timing module, which usually needs to be realized through the Internet of Things technology of the wifi module. It is a more direct method to obtain the time of the smart refrigerator through the wifi module, so as to judge the daytime / night time period 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; at the same time, users' usage habits vary widely, and it is difficult to analyze the rules statistically, so this solution cannot be promoted in applications

Embodiment 1

[0040] The refrigerator is placed in the home, and the temperature of the home environment usually changes periodically with the ambient temperature of the outside world within hours. Usually, the temperature reaches a peak around 12-14 noon, and then the temperature gradually drops, reaching a temperature trough around 6 o'clock in the morning; Users often open the refrigerator door during the day, and will reduce the number of refrigerator door openings after 18:00 at night. Usually, they will start sleeping 2 to 3 hours after the last door opening. After the user sleeps, the refrigerator will be controlled to perform night cooling mode. , to reduce the operating noise of the refrigerator. According to the number of times the user opens the door and the habit, the time with a longer interval should be that the refrigerator is basically at night, and the user opens the door for the first time every day, and the refrigerator is considered to be working during the day. At the s...

Embodiment 2

[0042] 1. Choose an electronically controlled refrigerator, which has already been equipped with an ambient temperature sensor, a door switch sensor, a timing module, and a main controller. Power on the refrigerator, and run the refrigerator according to the existing built-in refrigeration control program.

[0043] 2. Continuously collect and record the ambient temperature through the ambient temperature sensor 24 hours a day.

[0044] 3. Synchronously record the opening time within 24 hours.

[0045] Note: The timing of steps 2 and 3 is realized by the built-in timing module of the main controller of the refrigerator. The principle of calculating the time is to accumulate the time based on the power frequency of 50Hz. Each time interval period is 0.02 seconds, which can be converted into 4.32 for 24 hours. ×10 6 time period. Record the cycle of starting timing and mark it as 0, record and convert the cycle of the recorded data into interval time, every 4.32×10 6 A time per...

Abstract

The invention discloses a method for judging whether a refrigerator operates during the day or night, and relates to the technical field of refrigerator refrigeration operation control. In the present invention, the ambient temperature sensor continuously collects and records the ambient temperature at hourly intervals. The door switch sensor collects and records the opening time of the refrigerator. Continuously collect and record the ambient temperature and door opening time data for several days, analyze and calculate the time of the highest average temperature and the time of the lowest average temperature. Analyze the time period with the longest opening time interval of the refrigerator, and record the two door opening times corresponding to this time period. Calculate the mean value of the two door opening times of the longest door opening time interval for several consecutive days. The night time period is defined in the system, and the daytime period is defined in the system. The invention only uses the main controller of the electronically controlled refrigerator without increasing the cost of the refrigerator, and only by adding intelligent software, it can accurately judge whether the refrigerator is running in the day / night state, and it is convenient to control the refrigerator in an offline and intelligent judgment of the body. Cooling operation status.

Description

technical field [0001] The invention belongs to the technical field of refrigeration operation control of refrigerators, and in particular relates to a method for judging whether a refrigerator operates during the day or at night. Background technique [0002] With the improvement of people's living standards, refrigerators have entered thousands of households and become a necessity in people's daily life. The biggest difference between the refrigerator and many other household appliances is that the refrigerator is always in the cooling operation state; during the operation of the refrigerator, noise will be generated due to the operation of the compressor and the fan. The noise of this type of refrigerator can be directly perceived by users, so it is easy to cause users to complain about the quality of the refrigerator. [0003] According to the analysis of feedback data on user quality issues in the market, it can be seen that because the environment in which users use r...
