Description

Technical Field

[0001] The utility model belongs to the technical field of the air duct structure of a refrigerator, and particularly relates to an installation structure of an electric air duct damper and a refrigerator thereof. Background Art

[0002] At present, the air intake control of the refrigerator's fresh food air duct is generally controlled by an electric air damper. The temperature sensor monitors the temperature in the refrigerator compartment. When the temperature exceeds the set temperature, the temperature sensor will feedback the signal to the main board, and the main board controls the electric air damper to open, and the cold air enters the fresh food compartment, so that the temperature in the fresh food compartment drops; when the temperature in the fresh food compartment reaches the set temperature, the main board controls the electric air damper to close, and the cold air no longer enters the fresh food compartment.

[0003] The electric air damper is placed in the air duct joint between the fresh food air duct and the freezer air duct, and controls when the cold air flows from the freezer into the fresh food compartment. When the electric air damper is traditionally installed, since the air damper is installed downward from the fresh food compartment, the electric air damper wire harness is left for installation and connection in the fresh food compartment. When the fresh food air duct is installed at the bottom of the box body, the air damper wire harness will be pressed. During use, the cold air will flow out of the fresh food air duct along the wire harness, forming condensation and ice around the wire harness. Content of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides an installation structure of an electric air duct damper and a refrigerator thereof. By arranging an electric air damper and a damper box on the side of the electric air damper facing the freezer compartment, the condensation of the air damper wire harness into ice can be avoided.

Specific embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present application. The connection relationships shown in the drawings are only for clear description and do not limit the connection methods.

[0030] Specifically, as Figure 1As shown in the figure, an embodiment of the present application provides a refrigerator 500, which includes an installation structure of an air duct electric damper 200. This structure is mainly connected to the refrigerating compartment 510 and the freezing compartment 520 in the refrigerator 500. Specifically, an air duct joint 100 is provided between the refrigerating compartment 510 and the freezing compartment 520. The two ends of the air duct joint 100 are provided with a refrigerating air duct 530 and a freezing air duct 540. The refrigerating air duct 530 and the freezing air duct 540 are connected through the air duct joint 100, so that the refrigerating air duct 530 communicates with the freezing air duct 540. Among them, an electric damper 200 and a damper cover 300 are provided in the air duct joint 100. The electric damper 200 is installed in the air duct joint 100 through the damper cover 300. Specifically, an air duct cavity 110 is opened in the air duct joint 100, and the electric damper 200 and the damper cover 300 are located in the air duct cavity 110.

[0031] A fixing groove 111 is opened in the air duct cavity 110 at a position corresponding to the damper cover 300. As Figure 2 shown, the bottom surface of the fixing groove 111 faces upward, so that the damper cover 300 is installed in the fixing groove 111. For further stable installation, the space between the damper cover 300 and the fixing groove 111 is filled with sponge, so that the damper cover 300 is stable in the fixing groove 111. At the same time, the filling of the sponge enables the cold air flow in the refrigerator 500 to buffer the damper cover 300, avoiding the damper cover 300 from directly contacting the air duct cavity 110 and causing damage to the damper cover 300.

[0032] An electric damper 200 is also provided on the damper cover 300. Specifically, an installation groove 310 is opened on the damper cover 300 at a position corresponding to the electric damper 200. As Figure 2 shown, the installation groove 310 is arranged on the damper cover 300 in the direction towards the freezing compartment 520, and an electric damper 200 is arranged in the installation groove 310. The electric damper 200 is also installed in the installation groove 310 through the filling of sponge.

[0033] Among the electric damper 200, as Figure 3 shown, two air ports 220 and a gear box 210 are provided. The two air ports 220 are respectively installed on both sides of the gear box 210, and the gear box 210 drives the air ports 220 on both sides to open and close.

[0034] In the embodiment of the present application, the air ports 220 and the gear box 210 are both installed on the damper cover 300 through the installation groove 310, and the two air ports 220 are both communicated with the refrigerating air duct 530 and the freezing air duct 540. By adjusting the two air ports 220, the amount of cold air blown from the freezing compartment 520 into the refrigerating compartment 510 is controlled.

[0035] Among them, for the control of the air outlet 220, it is mainly controlled by a controller. The controller is installed inside the refrigerator 500. The controller and the electric air damper 200 are connected through the air damper wire harness 400. Specifically, the air damper wire harness 400 is connected to the gearbox 210, and the air damper wire harness 400 is attached to the side of the air duct cavity 110 facing the freezer compartment 520. Specifically, the air damper wire harness 400 is arranged inside the freezer air duct 540 and close to one side of the freezer air duct 540. As shown in the figure, arranging the air damper wire harness 400 at this position can avoid the freezing of the air damper wire harness 400. Specifically:

[0036] The cold air temperature in the freezer compartment 520 is generally -18°C, while the temperature in the refrigerator compartment 510 is generally about 2 - 5°C. The huge temperature difference causes the components in the refrigerator compartment 510 to condense into ice due to the extremely low temperature when the cold air in the freezer compartment 520 blows into the refrigerator compartment 510. When the air damper wire harness 400 is installed on the side of the refrigerator compartment 510, it will freeze due to the wind blowing from the freezer compartment 520, affecting the operation of the electric air damper 200. When the air damper wire harness 400 is installed inside the freezer compartment 520, due to the isolation of the electric air damper 200, it will always maintain a temperature of -18°C, thus avoiding the occurrence of freezing.

[0037] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
