Refrigerator and refrigerator compartment inner temperature sensing method

Abstract

The invention provides a refrigerator and refrigerator compartment inner temperature sensing method comprising the following steps: obtaining a plurality of temperature values measured by an infrared sensing assembly, wherein the infrared sensing assembly comprises a plurality of infrared sensing devices used for measuring the temperature of objects stored in a preset storage room of the refrigerator compartment; calculating a difference value between the maximum value and the minimum value of the temperature values; determining the maximum value weight coefficient and the minimum value weight coefficient according to the difference value; carrying out weighting and calculation for the temperature maximum value and the temperature minimum value by tacking the maximum value weight coefficient and the minimum value weight coefficient as the weight coefficients of the temperature maximum value and the minimum value; using the weighting and calculation result as the sensing temperature value of the storage room. The method can integratedly calculate and fuse the temperature data so as to obtain the measure value complying with the storage room real temperature, thus improving refrigerator compartment temperature detection accuracy.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigerator and a method for sensing the temperature inside a refrigerator compartment. Background technique [0002] Existing refrigerators usually use a temperature sensor arranged inside a compartment to sense the temperature around the location where it is arranged, and use the temperature as a basis for refrigeration control. [0003] However, when using this control method to control the refrigerator, when the temperature measured by the temperature sensor is higher than the preset value, the refrigerator starts cooling. In the case that the compartment is divided into multiple relatively independent storage spaces by shelf partitions, the temperature in the storage space where the items have just been placed may be higher than other storage spaces. Using the existing refrigerator temperature control method, it is necessary to Cooling the entire compartment as a whole results ...

AI Technical Summary

Problems solved by technology

When the compartment is divided into multiple relatively independent storage spaces by shelf partitions, the temperature in the storage space where items are just placed may be higher than other storage spaces. Using the existing refrigerator temperature control method, it is necessary to Refrigerating the entire room as a whole results in a waste of electric energy, especially when the volume of the room is large

[0004] In addition, for large refrigerator compartments, since the temperature at different locations may be inconsistent, the temperature measured by the temperature sensor cannot reflect the actual temperature inside the compartment. Using this temperature as the basis for refrigeration control may cause partial temperature unevenness. result in reduced storage
