Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in Figures 1 and 3, the present invention is based on the existing centrifugal fan, and realizes the simulation of the air volume distribution of the air duct by setting the sliding baffle 1 and the variable opening adjustment plate 2 to cooperate with it. Specifically, the centrifugal fan is composed of a centrifugal impeller 3 and a motor 4, and is installed on the inner tank of the refrigerator. A sliding baffle 1 is arranged around the centrifugal impeller 3. The sliding baffle 1 can divide the cold air thrown by the centrifugal impeller 3 into two parts. One stream simulates entering the freezer, and the other simulates entering the freezer and variable room; sliding baffle 1 needs to control the flow of the two streams of cold air as required, so it should be set as adjustable. Based on this, a sliding guide rail 7 is arranged ar...

Abstract

The invention discloses an experimental device for distributing air volume of a refrigerator air duct. The experimental device comprises a centrifugal fan, a sliding baffle plate, a variable opening adjusting plate and a sliding track, wherein the sliding track is arranged to surround the centrifugal fan, and the sliding baffle plate and the variable opening adjusting plate both are mounted on the sliding track. According to the scheme of the experimental device, the sliding baffle plate and the variable opening adjusting plate are arranged to control the flow direction of cold air blast, controlling the flow of the cold air blast with the guide ribs of the refrigerator is simulated, and the sliding baffle plate and the variable opening adjusting plate are mounted on the sliding guide rail to realize optional sliding; according to the requirements of adjustment, the adjustment and control of the volume of the cold air blast can be realized by adjusting the sliding baffle plate and the variable opening adjusting plate, and therefore, the experimental device is very convenient to use.

Description

[0001] technical field [0002] The invention relates to the field of refrigerators, in particular to an experimental device for air volume distribution of refrigerator air ducts. Background technique [0003] A centrifugal fan is arranged in the air duct between the refrigerating room, the variable room and the freezing room of the air-cooled refrigerator, and the centrifugal fan provides power for the flow of cold air in the room of the refrigerator. Specifically, guide ribs are provided around the centrifugal fan, and the guide ribs distribute the cold air sent by the centrifugal fan, and flow to each compartment of the refrigerator according to design requirements, thereby realizing cooling. Because the distribution of cold air is not random, but must meet the design requirements, it is necessary to debug the distribution of cold air when developing and assembling the refrigerator. The installation positions of the above-mentioned guide ribs directly affect the distribu...
