Embodiment 1

[0062] In Example 1, the tip angle of the tooth-shaped convex strip 130a formed on the inner wall of the air supply duct 130 is 45°; °. From Figure 6 It can be seen from the figure that in the 500Hz-1000Hz frequency band, the effect of an obtuse angle of 120° is worse than that of an acute angle of 45°. From this, it can be seen that the air flow noise in the air supply duct 130 having the protruding strip 130 a with an acute tooth tip angle is lower.

Embodiment 2

[0063] In Example 2, the tip angle of the tooth-shaped convex strip 130a formed on the inner wall of the air supply duct 130 of the refrigerator 100 is 30°. The tip angle is 30°, but the tip angle is worn. The protruding lines 130a with tooth tip angles below 45° are easier to wear, and here 30° is taken as an example, by Figure 7 It can be seen that after the tooth tip angle of the convex strip 130a formed on the inner wall of the air supply duct 130 is worn, the noise of the refrigerator 100 increases in the frequency range from 630 Hz to 1000 Hz. It can be seen that the tooth tip angle of the convex strip 130a should not be too small. Avoid excessively sharp tooth tip angles being worn and rounded, which will affect the noise reduction effect.

[0064] In addition, in the refrigerating cycle system of the refrigerator 100, the refrigerant at the capillary injection port has a severe gas-liquid phase transition, and the flow rate of the refrigerant is in the transonic regi...

Abstract

The invention provides an air-cooled refrigerator. The air-cooled refrigerator comprises an air supply duct, wherein a plurality of convex strips protruding towards the inner space of the air supply duct are arranged on the inner wall of the air supply duct, the convex strips extend in the extension direction of the air supply duct, and the convex strips are distributed in parallel in the circumferential direction of the inner wall of the air supply duct, so that every two adjacent convex strips are utilized to form a groove-shaped flow channel, and the air flow in the air supply duct is dispersed to reduce the air flow noise and improve the sound quality of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air-cooled refrigerator. Background technique [0002] In an air-cooled refrigerator, the cold airflow formed after exchanging heat with the evaporator is transported to the storage compartment of the refrigerator through the air supply duct to reduce the temperature of the storage compartment. [0003] At present, one of the main problems of the air-cooled refrigerator is that the air flow in the air duct is noisy, which affects the sound quality of the refrigerator and reduces the user experience. Contents of the invention [0004] In view of the above problems, an object of the present invention is to provide an air-cooled refrigerator that overcomes the above problems or at least partially solves the above problems. [0005] A further object of the present invention is to reduce airflow noise in the air duct and improve the sound quality of the refrigerator...
