Problems solved by technology

[0005] 1. There are few adjustment gears, and the temperature cannot be adjusted continuously. It can only be adjusted in stages, which cannot meet the needs of use;
[0006] 2. It is unreliable to use the protrusion 23 and the arc groove 13 to engage and position. Under the condition of transportation or vibration, due to the weight of the handle and the weight of the adjustment ring 2 are unbalanced, it is easy to cause the adjustment ring 2 to rotate, which is caused by the adjusted temperature. Change

Embodiment 1

[0041] Figures 4, 5 and 6 are structural diagrams of a specific embodiment of the adjustable air volume refrigerator air duct of the present invention, wherein: Figure 4 is a structural schematic diagram of the combination of the air volume adjustment device and the rear side panel of the inner container. Figure 5 is a schematic diagram of the combination with the air duct. Fig. 6 is a schematic structural view of the air volume regulating device.

[0042] As shown in Figures 4 and 6, the air volume adjustment device 20 disclosed in this embodiment is realized by using a rack and pinion translation plate mechanism. In the slideway 23 perpendicular to the axis of the air duct, a windshield 24 is fixed to the rack 21, a gear 25 is engaged with the rack 21, and is pivotally arranged on the inner wall of the inner tank through a rotating shaft, and a hand wheel 26 is fixed with described rotating shaft.

[0043] Referring to Fig. 5, the air duct is arranged in the insulation foa...

Embodiment 2

[0048] Fig. 7 is a structural diagram of another specific embodiment of the refrigerator air duct with adjustable air volume of the present invention. It can be seen from Fig. 7 that the air volume adjustment device in this embodiment is a crank slider translational plate mechanism, and a slider slide 31 Set in the slideway 32 perpendicular to the axis of the air duct 100 fixed to the liner, a windshield 33 is fixed to the slider 31, and a runner 34 is connected to the slider 31 through an eccentrically arranged connecting rod 35. Hinged, the runner 34 is pivotally arranged on the wall of the inner tank through a rotating shaft, and a hand wheel 36 is fixed to the rotating shaft. Turning the hand wheel 36 will drive the running wheel 34 to rotate through the rotating shaft.

[0049]In order to enable the wind deflector to move along the direction perpendicular to the axis of the air duct, a receiving groove 37 for accommodating the wind deflector 33 is provided at the position...

Embodiment 3

[0054] Fig. 8 is a structural diagram of another specific embodiment of the refrigerator air duct with adjustable air volume according to the present invention. It can be seen from Fig. 8 that the air volume adjustment device in this embodiment is a rotating plate mechanism, and a rotating shaft is provided in the air duct 100. 40 is a fixed windshield rotating plate 41, the rotating shaft is pivotally arranged on the inner tank wall, and the first handwheel 42 is fixed to the rotating shaft.

[0055] The hand wheel 42 is fixed on the rotating shaft in the refrigerator compartment.

[0056] The axis of the rotating shaft is perpendicular to the axis of the air duct.

[0057] In order to fix the rotating shaft 40 after adjustment, a bushing with a tapered surface 43 and an external thread 44 is protruded on the end surface of the shaft hole of the pivoting shaft 40. The tapered surface of the bushing has at least 3 elastic holes along the axis. Groove, a nut 45 with the inner ...

Abstract

The invention relates to a refrigerator air duct which can adjust air volume. The air duct is arranged between a freezer compartment and a refrigerator compartment, and fixed with an internal bladder of the refrigerator, a vertical section of the air duct is provided with an air volume adjusting device, wherein, the air volume adjusting device is a gear-rack transitional plate mechanism, the rack is arranged in a slideway which is fixed with the internal bladder and vertical to an axis of the air duct through a slider, a wind shield is fixed with the rack, a gear is meshed with the rack and pivoted on the wall of the internal bladder through a shaft, and a handwheel is fixed with the shaft. The invention uses adjusting mechanisms, such as the gear, the rack, the crank-slider, etc. to replace a stepped positioning adjustment of a plurality of positioning blocks, thereby achieving continuous temperature adjusting and fulfilling using requirements of users; meanwhile, the invention uses a planet gear with self lock function, a gear rack mechanism and a regulating handwheel, positioning can be reliable, a rotation of a regulating ring caused by unbalanced weight is prevented, and the well adjusted temperature can not be changed, under transportation or vibration conditions.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator air duct with adjustable air volume. Background technique [0002] The structure of a small air-cooled refrigerator with a refrigerator and a freezer is shown in Figure 1. The fan 11 located in the machine room 1 sends the low-temperature cold air near the evaporator 12 into the refrigerator 3 and freezer 4 respectively through the air duct 7. , the temperature of the refrigerating chamber and the freezing chamber is realized by controlling the temperature of the refrigerating chamber detected by the temperature sensor 5 arranged in the refrigerating chamber to control the operation of the compressor. Since the temperature sensor detects the temperature of the refrigerating chamber, the temperature control of the refrigerating chamber is more accurate , and the temperature of the freezing chamber is realized by adjusting the distribution ratio of the low-temperature cold air enter...
