Control method for automatically identifying quick-freezing requirement

Abstract

The invention discloses a control method for automatically identifying a quick-freezing requirement. The control method comprises the following steps of: calculating whether the time from the time when a refrigerator is defrosted last time is longer than 4 hours or not; if so, calculating the temperature of an evaporator at the stop moment of a compressor at the time and subtracting the temperature parameter DTF of the evaporator at the stop moment of the compressor last time; if the DTF is greater than or equal to 1 DEG C, enabling the refrigerator to enter a quick-freezing mode; and after the refrigerator enters the quick-freezing mode, enabling the compressor to continuously run for 24 hours and then returning to a main program. According to an algorithm disclosed by the invention, based on monitoring of the temperature of the evaporator of the refrigerator, the quick-freezing requirement can be accurately identified and the on-off of the quick-freezing mode can be automatically controlled, so that the quick-freezing requirement of a user is met and the energy consumption of the refrigerator is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator control methods, and more specifically, relates to a control method for automatically identifying quick-freezing requirements. Background technique [0002] Existing refrigerator refrigeration equipment is generally equipped with a quick-freezing function. When the user puts a large amount of food in a short period of time, the temperature in the freezer will rise rapidly due to the large amount of heat emitted by the food just placed, making the temperature of the food originally stored in the freezer Following the changes, the storage quality of food is affected. At the same time, due to the sudden increase in heat load in the freezer, it is necessary to immediately replenish the cooling capacity so that the food can quickly pass through the ice temperate zone to ensure food preservation requirements. The quick-freezing function will address this situation, and control the refrigerator refr...

[0002] Existing refrigerator refrigeration equipment is generally equipped with a quick-freezing function. When the user puts a large amount of food in a short period of time, the temperature in the freezer will rise rapidly due to the large amount of heat emitted by the food just placed, making the temperature of the food originally stored in the freezer With the changes, the storage quality of food is affected. At the same time, due to the sudden increase in heat load in the freezer, it is necessary to immediately replenish the cooling capacity so that the food can quickly pass through the ice temperate zone to ensure food preservation requirements.

The quick-freezing function will address this situation, and control the refrigerator refrigeration equipment to break through the set control temperature that is running, and quickly reach the lowest temperature that the refrigerator refrigeration equipment can reach, so that the food can be frozen at the fastest speed. When the quick-freeze execution is completed, the refrigerator compresses However, the existing quick-freezing function is generally opened manually. When the user starts the quick-freezing function for a period of time, the user still needs to judge whether the quick-freezing is completed. This function is not smart enough and convenient, and even makes the refrigerator consumes more energy, so this needs to be improved
