Problems solved by technology

[0003] The existing instant freezing function is realized in the freezer compartment of the refrigerator. If the food such as chilled meat is placed in the freezer for too long, it will freeze inside and lose the meaning of instant freezing, and the surface temperature of the food cannot be monitored in real time. , so the temperature control is not accurate

Embodiment 1

[0032] This embodiment provides a refrigerator with instant freezing function, such as figure 1 As shown, the refrigerator has a temperature-changing chamber 1, and an air outlet 2 is opened on the rear wall of the temperature-changing chamber 1. A drawer 3 can be drawn and drawn in the variable room 1, and an aluminum instant freezing tray 6 is arranged in the drawer 3, and the area where the aluminum instant freezing tray 6 is located is used as an instant freezing zone 4 of the refrigerator.

[0033] A temperature detector 9 is arranged above the instantaneous freezing zone 4, preferably installed on the inner wall of the temperature-changing chamber 1, and the temperature detector 9 is used to detect the surface temperature of the items put into the instantaneous freezing zone 4, so that the temperature can be controlled more accurately.

[0034] In this embodiment, the fan 5 arranged in the air duct of the variable room 1 is a variable frequency fan, and the controller co...

Embodiment 2

[0040] This embodiment provides a refrigerator with instant freezing function, such as figure 2 As shown, the structure of the refrigerator is basically the same as that of Embodiment 1, including a temperature-changing room 1, and an air outlet 2 is provided on the rear wall of the temperature-changing room 1 . A drawer 3 can be drawn and drawn in the variable room 1, and an aluminum instant freezing tray 6 is arranged in the drawer 3, and the area where the aluminum instant freezing tray 6 is located is used as an instant freezing zone 4 of the refrigerator. A temperature detector 9 is arranged above the instantaneous freezing zone 4 .

[0041] The difference is that, in this embodiment, a blower fan 5 and a one-to-two electric damper 11 are arranged in the air duct of the temperature-changing room 1, wherein, as image 3 As shown, the first damper 7 is used in the normal cooling mode, the second damper 8 is used in the instant freezing mode, and the controller controls th...

Abstract

The invention discloses a refrigerator with an instant refrigeration function, and relates to the technical field of refrigeration devices. The refrigerator is designed to solve the problems that an existing refrigerator with the instant refrigeration function is high in cost, poor in instant refrigeration effect and the like. The refrigerator comprises a controller, an interchangeable temperature chamber, an air outlet formed in the rear wall of the interchangeable temperature chamber, and a drawer arranged in the interchangeable temperature chamber. An instant refrigeration area is arranged in the interchangeable temperature chamber. A draught fan for blowing cold air into the interchangeable temperature chamber from the air outlet is arranged in an air duct of the interchangeable temperature chamber. Meanwhile, the invention provides a control method for the refrigerator. The instant refrigeration area is arranged in the interchangeable temperature chamber of the refrigerator, the controller controls and increases the air volume of the draught fan at the air outlet, and therefore the cooling speed of surfaces of objects in the instant refrigeration area is increased, and instant refrigeration is achieved; the instant refrigeration area is arranged in the interchangeable temperature chamber, the temperature is higher than the temperature in a refrigeration chamber, heat preservation can be achieved for the interior of food through crystallizing layers on surfaces of the food, and it is ensured that the food can not be completely frozen even after being placed in the instant refrigeration area for a long time.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator with an instant freezing function and a control method for the refrigerator. Background technique [0002] With the improvement of people's living standards, users' demand for instant freezing of refrigerators is becoming stronger and stronger. For example, people like to drink ice water and ice drinks in summer. Drinking at any time without freezing, and at the same time the temperature is around -5°C, which needs to be realized through the instant freezing function. At the same time, the instantaneous freezing function can well preserve cold fresh meat and other foods, so that the surface of the food is frozen, but the inside is not frozen, ensuring that the cells will not be damaged and the nutritional value will not be lost. [0003] The existing instant freezing function is realized in the freezer compartment of the refrigerator. If the food s...
