AI Technical Summary

Technical Problem

The cooling efficiency of the variable temperature compartment in existing refrigerators is low, which leads to the loss of nutrients in food and makes it impossible to refrigerate quickly.

Method used

A quick-freezing fan is installed between the variable temperature chamber and the freezer chamber or freezer duct. Low-temperature cold air is blown into the variable temperature chamber through the first air outlet, and combined with the cold air flow of the refrigeration duct to assist in cooling. The temperature is precisely controlled by the air damper to achieve rapid refrigeration.

Benefits of technology

It achieves rapid cooling of the variable temperature chamber, reduces the loss of nutrients in food, provides precise temperature control, and can maintain the temperature after reaching the set temperature.

Abstract

The utility model discloses a temperature-changing space air duct system capable of rapidly cooling and a refrigerator, relates to the field of refrigerator air duct systems, and aims to solve the problems that a temperature-changing chamber in the prior art is slow in cooling and cannot realize rapid refrigeration, and adopts the technical scheme that a first air opening is formed in the side wall of the temperature-changing chamber and is communicated with a freezing chamber; a quick-freezing fan is installed at the first air opening and can suck low-temperature cold air flow in the freezing chamber into the variable-temperature chamber so that the variable-temperature chamber can be quickly cooled, a second air opening is formed in the refrigeration air duct and communicates with the variable-temperature chamber, and cold air flow in the variable-temperature chamber can enter the variable-temperature chamber to assist in cooling, and air doors are additionally installed at the first air opening and the second air opening. And the communication state of the temperature changing chamber can be precisely regulated and controlled, so that different cooling and heat preservation requirements are met. The variable-temperature chamber can be rapidly cooled, and the effects of rapidly refrigerating food and reducing loss of nutrient substances of the food are achieved.
