Problems solved by technology

[0005] The object of the present invention is to provide an air duct assembly structure for an air-cooled refrigerator and a refrigeration control method thereof. According to the temperature value detected by the temperature sensor, the electric damper is driven to rotate, and then the middle air chamber and the first air supply chamber and the first air supply chamber are adjusted. The cooling capacity between the second air supply chambers can realize three-way combined air supply, so that the air in the refrigerator can be evenly circulated; and the temperature control is precise, which solves the problem of complex design of the existing air duct structure and cannot ensure the uniformity of the refrigerator. The problem of small fluctuations in air supply and temperature difference

Embodiment 1

[0038] Such as Figure 1-2 As shown, the present invention is an air duct assembly structure for an air-cooled refrigerator, including a front cover 1, the front cover 1 is installed on the back of the refrigerator compartment, and a temperature sensor 2 is installed on the bottom side of the front cover 1 , the temperature sensor 2 is used to collect the temperature in the refrigerating room, and feed back the detected temperature value to the control system. An air duct plate 3 is fixedly installed on the other side of the front cover plate 1, and a rear cover plate is installed on the side of the air duct plate 3. 4;

[0039] Such as figure 1 and image 3 As shown, a horizontal plate 301 is fixed on the top of the air channel plate 3 along the width direction, and a first baffle plate 302 and a second baffle plate 303 are fixed side by side in the middle of the side surface of the air channel plate 3 along the length direction; The side edges are respectively fixed with ...

Embodiment 2

[0058] The current set temperature of the refrigerating room is 4°C, the temperature of the refrigerating room detected by the temperature sensor 2 is 20°C, the compressor is running, the electric damper 901 is turned 90 degrees, and is fully open; at this time, the cooling capacity passing through the rectangular frame 9 into the middle air chamber 5 and the air passage 801 respectively; and the cooling capacity in the air passage 801 enters the first air supply chamber 6 and the second air supply chamber 7 respectively; the first side air outlet 601 and the second side air outlet 701 and the front air outlet 501 are all turned on for air supply; the fan runs at high speed;

[0059] Refrigerator start and stop control:

[0060] Start-up temperature point: TON = set temperature + 1,

[0061] Shutdown temperature point: TOFF=TON-2,

[0062] Then when the set temperature is 4°C, the corresponding start-up point temperature TON=4+1=5,

[0063] The corresponding stop point temp...

Abstract

The invention discloses an air duct assembly structure for an air-cooled refrigerator and a refrigeration control method of the air duct assembly structure for the air-cooled refrigerator, and relatesto the technical field of air-cooled refrigerators. The structure comprises a front cover plate, wherein a temperature sensor is installed on one side face of the bottom of the front cover plate, theother side face of the front cover plate is fixedly provided with an air duct plate, and a rear cover plate is installed on the side surface of the air duct plate; a transverse plate is fixed to thetop of the air duct plate along the width direction, and a first baffle and a second baffle are arranged in the middle of the side surface of the air duct plate in parallel along the length direction;and the side surface edges of the front cover plate are fixedly provided with a first air plate and a second air plate in the length direction correspondingly. According to the structure and the method, an electric air door is driven to rotate according to the temperature value detected by the temperature sensor, then the cooling capacity between a middle-way air cavity and a first air supply cavity and the cool capacity between the middle-way air cavity and a second air supply cavity are adjusted, the three-way combined air supply can be realized, and the air in a refrigerating chamber can be uniformly circulated; and the temperature control is accurate, so that the freshness and the mouth feel of food are ensured.

Description

technical field [0001] The invention belongs to the technical field of air-cooled refrigerators, and in particular relates to an air duct assembly structure for an air-cooled refrigerator and a refrigeration control method thereof. Background technique [0002] With the continuous improvement of user needs, large-size and large-capacity refrigerators are more and more popular with consumers; for air-cooled refrigerators, when the width of the refrigerator is large, the traditional front air supply or side air supply structures are useless. There are certain limitations, which can easily lead to excessive temperature in local areas, poor temperature uniformity, and slow cooling speed; for air-cooled refrigerators, the air circulation in the refrigerator is sufficient, the heat transfer temperature difference is small, the more uniform the temperature, the smaller the temperature fluctuation can be. It has the best preservation effect on fruits, vegetables and food. [0003] ...
