Problems solved by technology

However, when the preset angle is too small, it is impossible to quickly cool the variable room. When the preset angle is too large, after the cooling of the variable room is completed, the temperature of the variable room cannot be closed in time, causing the temperature of the variable room to be too low and the temperature of the variable room to fluctuate. Larger, it can be seen that this method cannot accurately control the temperature of the variable room

Embodiment 1

[0024] An embodiment of the present invention provides a method for controlling a temperature-changing room of a refrigerator. The refrigerator includes a freezing room, a refrigerating room, and a temperature-changing room. The air in the freezing chamber and the variable temperature chamber is convected through the variable temperature damper, thereby cooling the variable temperature chamber, as figure 1 As shown, the method includes:

[0025] 101. When the temperature of the variable temperature chamber is greater than or equal to the opening temperature of the variable temperature damper, open the angle of the variable temperature damper to a target angle.

[0026] The method provided by the embodiment of the present invention can be applied to a side-by-side refrigerator with a single refrigeration system, and is used to control the temperature of the temperature-changing chamber in the refrigerator more precisely.

[0027] Wherein, when the temperature of the variable r...

Embodiment 2

[0090] The embodiment of the present invention also provides a method for controlling the temperature-changing room of a refrigerator, the temperature-changing room is located in the refrigerating room, such as image 3 As shown, the method includes:

[0091] 301. When the temperature of the variable temperature chamber is greater than or equal to the opening temperature of the variable temperature damper, obtain preset parameters, where the preset parameters include at least one of the temperature of the external environment where the refrigerator is located, a first difference, and a second difference.

[0092] Wherein, the opening temperature of the variable temperature damper can be preset, the first difference refers to the difference between the current temperature of the variable temperature room and the temperature of the freezing room, and the second difference refers to the difference between the current temperature of the variable temperature room and the temperature...

Embodiment 3

[0106] The embodiment of the present invention provides a refrigerator temperature-changing room control device 40, which is used to implement figure 1 In the control method for changing the temperature-changing room of the refrigerator, the refrigerator includes a freezing room, a refrigerating room and a changing room. Convection with the air in the variable temperature chamber through the variable temperature damper, thereby cooling the variable temperature chamber, such as Figure 4 As shown, the device 40 includes:

[0107] The first execution unit 401 is configured to open the angle of the variable temperature damper to a target angle when the temperature of the variable temperature chamber is greater than or equal to the opening temperature of the variable temperature damper;

[0108] The second execution unit 402 is configured to reduce the angle of the variable temperature damper according to preset rules when the temperature of the variable temperature chamber is lo...

Abstract

The embodiment of the invention discloses a method and device for controlling a variable temperature room of a refrigerator, which relate to the field of refrigerators and are used to control the temperature of the variable temperature room more accurately. The refrigerator includes a freezing room, a refrigerating room and a temperature-changing room, and a temperature-changing damper is arranged between the temperature-changing room and the freezing room. When the temperature-changing damper is opened, the air in the freezing room and the changing room passes through the The variable temperature damper performs convection to cool the variable temperature chamber. The method includes: when the temperature of the variable temperature chamber is greater than or equal to the opening temperature of the variable temperature damper, opening the angle of the variable temperature damper to a target angle; During the process in which the temperature of the variable temperature chamber drops to the closing temperature of the variable temperature damper, the angle of the variable temperature damper is reduced according to preset rules; when the temperature of the variable temperature chamber is reduced to the closing temperature of the variable temperature damper, it is closed The variable temperature damper. The method provided by the embodiment of the present invention can be used to precisely control the temperature of the variable room.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a method and device for controlling a variable temperature chamber of a refrigerator. Background technique [0002] In a side-by-side refrigerator with a single refrigeration system, after being refrigerated by the refrigerating evaporator, the hot air is diverted from the refrigerating air duct by the fan, and part of the cold air is sent out through the refrigerating air outlet to cool the freezing chamber, while the other part of the cold air enters the refrigerating air duct through the damper. Refrigerate the refrigerator. The variable room in the side-by-side refrigerator of the single refrigeration system is generally set in the refrigerating room, and the center beam between the variable room and the freezing room is provided with an opening and a variable temperature damper. When the temperature variable damper is opened, the air in the freezing room and the air in the varia...
