Abstract
The utility model relates to an air cooling refrigerator and discloses a frost-free refrigerator air damper. The utility model is characterized in that the louver type air damper comprises fan blades, a connection bar and fan blade bushings, wherein rotary shafts at two ends of the fan blades are sleeved in the fan blade bushings which are arranged in a fan blade support, and each of the rotary shafts which are connected with the connection bar is disposed in the center of each fan blade. The frost-free refrigerator air damper has simple structure, creates totally closed defrosting space for the refrigerator, not only improves the de-frosting effect of the refrigerator, but also can reduce energy consumption of the whole refrigerator.
Description
Technical field
The present invention relates to the refrigerator field, more particularly, relate to a kind of frost-free refrigerator air door.
Background technology
The ducting part great majority of frost-free refrigerator are at present: the sub-assembly of injection moulding air channel or injection moulding air channel cover plate and air channel foam.The air outlet shape and the air-out mode of this kind structure ducting part are fixed, and are in a kind of normally open.Under defrost state, if air outlet is an open mode, during the work of defrosting heating tube, hot gas rises, can pass in the casing by air outlet, influence storage temperature, and because the loss of defrosting heat, can not concentrate the heat defrosting, the heating tube working time prolongs, thereby increases energy consumption.
Summary of the invention
The present invention is directed to the shortcoming of frost-free refrigerator defrosting heat outflow loss, the air port can be closed fully when a kind of defrost state was provided, the frost-free refrigerator air door that the routine work state is opened fully, and the overall performance of raising refrigerator cuts down the consumption of energy.
Technical scheme of the present invention is as follows: a kind of frost-free refrigerator air door, it is characterized in that air door is a venetian blind type, and described air door comprises fan blade, connecting rod, fan blade axle sleeve; The rotary axle box at fan blade two ends puts in blade shaft, and blade shaft is placed in the air door support, is provided with the turning cylinder that links to each other with connecting rod in the middle of the fan blade.
Further, the air door support is fixed on the cover plate of air channel.Further, air door support and air channel cover plate are one-body molded.
Further, described connecting rod and fan blade all are moulding.
Further, described fan blade axle sleeve is a metal material.Further, zinc-plated processing has been passed through on described fan blade axle sleeve surface.Further, described fan blade axle sleeve is made by stainless steel.
Fan blade of the present invention presents " rotation venetian blind type " shape structure, linkage utilization parallelogram lindage principle.
Frost-free refrigerator involved in the present invention comprises sensing device, stepper motor etc., and its operation principle is: when Defrost heater is started working, give signal of stepper motor by sensing device, the step motor control connecting rod drives the fan blade closure; After withdraw from defrost, compressor is opened some minutes, give signal of stepper motor by sensing device again, the step motor control connecting rod drives fan blade and opens.
Compared with prior art, frost-free refrigerator air door structure of the present utility model is simple, to the defrost space that refrigerator has been created a complete closed, has not only improved the defrost effect of FCL, and can reduce the FCL energy consumption.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is done to describe further.
Frost-free refrigerator air door of the present utility model is a venetian blind type.As shown in Figure 1, air channel cover plate 1 is one-body molded with air door support 2.As shown in Figure 2, fan blade 3 two ends are provided with turning cylinder 4, and the centre of fan blade 3 is provided with the turning cylinder 5 that matches with connecting rod.Fig. 4 is the schematic diagram of connecting rod 7, and connecting rod is provided with the hole 8 of matching with the turning cylinder 5 of fan blade 3 centres, is provided with and motor interactional protruding 9.Fig. 5 is the schematic diagram of air door, and fan blade axle sleeve 6 is placed on the air door support 2, and the turning cylinder 4 at fan blade 3 two ends is placed on the fan blade axle sleeve 6, and the turning cylinder 5 in the middle of the fan blade 3 matches with the hole 8 of connecting rod 7, and connecting rod 7 can drive fan blade 3 rotations.
When Defrost heater is started working, give signal of stepper motor by sensing device, step motor control connecting rod 7 drives fan blade 3 and closes (as shown in Figure 7), cut off the transmission of aerofoil both sides heat, treat that defrosting finishes, compressor was opened after two minutes, gave signal of stepper motor by sensing device again, control link 7 drives fan blade 3 and opens (as shown in Figure 6), enters normal operating conditions.Present embodiment is simple in structure, and good looking appearance is generous, to the defrost space that refrigerator has been created a complete closed, has not only improved the defrost effect of FCL, and can reduce the FCL energy consumption, and practicality is good.
