Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to an air volume regulating device for an air-cooled refrigerator. Background Art

[0002] The market share of air-cooled frost-free refrigerators is increasing year by year, and consumers are more inclined to use such products. In temperature zone and multi-compartment products, there are currently two main ways to control the distribution of air volume between temperature zones:

[0003] The first method is an electric damper device, which distributes the air volume of each compartment by the opening and stopping time of the damper. The advantage of this type of structure is that it is intelligentized through electronic control, does not require human intervention, and the temperature control is relatively accurate. The damper opens under the designed temperature requirements. However, this type of structure is costly, and because the electric damper itself has a certain fatigue life, it will be stuck or fail in a low temperature and high humidity environment for a long time; the second method is a mechanical lever or knob device, which manually adjusts the stroke of the mechanical lever or knob. The stroke determines the size of the air supply section between each compartment, which ultimately affects the air volume distribution and the temperature. The main advantages of this structure are low cost, strong reliability, and no defects caused by moisture. The disadvantage is that this structure is a fuzzy temperature control type and cannot achieve precise control. Especially in some harsh working conditions, if the user forgets to change the lever stroke in time, there will be an inappropriate ventilation section at some positions of the lever or knob, resulting in a small air volume in the compartment and insufficient temperature. Summary of the invention

[0004] The object of the present invention is to provide an air volume regulating device for an air-cooled refrigerator, which can adjust the air volume at different positions through a lever or knob structure design, so that the air volume distribution of each compartment can meet the basic requirements of users; in addition, the air volume regulating device of the present invention can be used not only in a refrigerated compartment, a frozen compartment, and a cold compartment, but also in a compartment with any refrigeration temperature zone requirement.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is an air volume regulating device for an air-cooled refrigerator, comprising an air duct main body, a fixed outer cover is arranged on the outer surface of the air duct main body, and a sliding groove is opened on the surface of the fixed outer cover; a groove is opened in the horizontal direction of the air duct main body, a through hole is opened on one side of the groove, and a blind hole is opened on the other side of the groove, the through hole and the blind hole are both connected to the groove, a ventilation regulating component for realizing the air volume regulating function is clamped in the groove, and slides horizontally in the groove; the ventilation regulating component comprises a lining box and a regulator; the regulator is arranged on the outer surface of the lining box, and the regulator passes through the sliding groove and slides in the sliding groove.

[0007] Furthermore, the regulator is a lever or a knob.

[0008] Furthermore, the channel is a square, oval or waist-shaped structure.

[0009] Furthermore, the liner box includes a slot plate matched with the slot, and an adjustment plate matched with a through hole is arranged on the surface of the slot plate.

[0010] Furthermore, slots for adjusting the air volume are provided on the side wall of the adjustment plate.

[0011] Furthermore, a plurality of ventilation holes of different sizes are provided on the surface of the slot plate to adjust the air volume at different positions.

[0012] Furthermore, the ventilation holes are circular, square or irregular polygonal.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention uses a lever or knob structure design to adjust the air volume at different positions, so that the air volume distribution in each room can meet the basic requirements of users.
