An intelligent quick-freezing control method for a refrigerator

Abstract

The invention discloses an intelligent quick-freezing control method of a refrigerator. When a large amount of fresh food is placed into a freezing chamber of the refrigerator and needs to be frozen in a short period of time, the rotation speed or the operation time of an inverter compressor is controlled, and the operation time of a fixed-frequency compressor is controlled. When the temperature of a sensor is higher than a set upper limit value at which a quick-freezing function can be automatically achieved, it is judged automatically that the refrigerator should enter a quick-freezing state; a target value at which the quick-freezing function is automatically stopped is set for the temperature sensor, when the refrigerator enters the quick-freezing state and runs at the target value for a period of time, the quick-freezing state is automatically switched and the compressor begins to operate normally. The intelligent quick-freezing control method of the refrigerator has the advantages that the refrigerator can be controlled to enter the quick-freezing state, the work state of the refrigerator can be adjusted according to the temperature in the refrigerator and the quick-freezing duration, and the aims of achieving the quick-freezing function and conserving energy are achieved; the method is suitable for being used for the refrigerator, an ice tank and other refrigerating equipment.

Description

Technical field [0001] The invention relates to an intelligent quick freezing control method of a refrigerator. Background technique [0002] Under normal circumstances, if a large amount of hot food and items are put in the freezer compartment of the refrigerator in a short time, the temperature in the freezer compartment will rise significantly, which not only affects the temperature of the original food and items, but also causes the refrigerator to operate for a long time, so the current market In response to this situation, many electric-controlled refrigerators above have designed special programs with "quick-freezing" functions, allowing users to feel humane care. [0003] However, the current "quick freezing" function is entered by manual operation (manual key is adjusted to the "quick freezing" state), and the "quick freezing" function has a fixed time limit. In this way, there are two unreasonable states, that is, relatively few fresh foods are frozen at a fixed time and...

Problems solved by technology

[0002] Under normal circumstances, if a large amount of hot food and items are placed in the freezer compartment of the refrigerator in a short period of time, the temperature in the freezer room will rise sharply, which not only affects the temperature of the original food and items, but also causes the refrigerator to run for a long time, so the current market Many electronically controlled refrigerators on the Internet have designed special programs with the function of "quick freezing" in response to this situation, so that users can feel humanized care

[0003] However, the current "quick freezing" functions are all entered manually (manually press the button to adjust to the "quick freezing" state), and the "quick freezing" function has a fixed time limit

In this way, there are two unreasonable states, that is: within a fixed time, relatively few fresh foods are frozen at too low a temperature to cause a waste of electric energy, or when more fresh foods arrive at the fixed time and exit the "quick freezing" function, there is still Did not drop to ideal temperature

And the user can't judge whether the "quick freezing" function has been fully realized because he can't know the actual temperature in the box.
