Refrigerator compartment temperature control method, device and refrigerator with same

Abstract

The invention provides a refrigerator compartment temperature control method, which comprises the following steps that: the temperature of a refrigerator compartment is acquired at a predetermined time interval for N times to obtain N temperature sample values; the N temperature sample values are summed to obtain a first temperature value, an average value of the N temperature sample values is calculated and the average value is rounded to obtain a second temperature value; the first temperature value is complemented to obtain a residue of the first temperature value, the residue is compared with N / 2, and a target temperature value is obtained according to the comparison result and the second temperature value; and the compartment temperature is controlled according to the target temperature value. According to the acquisition method provided by the invention, the acquired compartment temperature is more accurate, and further the control of the refrigerator for the compartment temperature is improved, so that the fluctuation of the compartment temperature is stabilized. The invention also provides a refrigerator compartment temperature control device, and a refrigerator with the same.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a method for controlling the temperature of a compartment of a refrigerator, a device for controlling the temperature of a compartment of a refrigerator, and a refrigerator with the device. Background technique [0002] For refrigerators, temperature is the most important parameter of the refrigerator system. The refrigerator controls the start and stop of equipment such as compressors and fans by detecting the actual temperature of each room to realize the temperature control of each room. Therefore, it is necessary to accurately collect the actual temperature of each compartment. [0003] Most of the existing refrigerator temperature acquisition methods use the sliding average filtering method, that is, use temperature sensors, such as: NTC (negative temperature coefficient) thermistors, thermocouples, platinum resistors, etc. to collect the temperature of the ...

AI Technical Summary

Problems solved by technology

However, the temperature values ​​calculated and measured by the existing moving average filtering and other temperature acquisition methods are not accurate enough. For example, when the actual temperature of the compartment is 3.9°C, the measured temperature value obtained by the existing method is often 3°C. In the worst case, the difference between the actual temperature and the measured temperature is close to 1°C, which causes the temperature of each room to be inaccurate, which is not conducive to the preservation of some foods with relatively high temperature requirements.
