Abstract
The utility model relates to an internal circulating blower structure for a refrigerated storage cabinet. The utility model adopts a sealed drum-type blower only provided with an input air port and an output air port, so that the air entering from the input air port is completely discharged from the output air port, heat exchange is carried out through an evaporator, the efficiency of the blower is effectively raised.
Description
The utility model relates to a kind of interior circulating fan structure that is used for refrigerator.
Circulating fan structure in the present normally used refrigerator, be made up of blower fan plate washer, blower fan and evaporimeter, wherein blower fan is a wing leaf formula blower fan, is positioned at evaporimeter top, both all are positioned at blower fan plate washer back, the close blower fan part and the close rectangular stepped change of evaporator section of blower fan plate washer.During use, the air on refrigerating chamber top enters blower fan plate washer back under the effect of blower fan, and to all directions diffusions, cause have only pass through evaporimeter wherein a part of wind direction under and carry out heat exchange after, flow to refrigerating chamber, there is the deficiency that the input and output air quantity is few and fan efficiency is low in this structure.
The purpose of this utility model is to overcome above-mentioned defective, and a kind of interior circulating fan structure of refrigerator that strengthens input and output air quantity and fan efficiency is provided.
The utility model is achieved in that on the prior art basis, adopts blower fan for the closed cylinder formula blower fan in input air port and output air port is only arranged;
The input air channel of blower fan becomes 90 ° to 100 ° angles with the output air channel;
The input air port of blower fan is greater than the output air port;
The close blower fan part of blower fan plate washer is through domatic reducing near evaporator section.
Adopt the utility model, the air on refrigerating chamber top enters in the blower fan through the input air port by fan action, because blower fan adopts the drum-type enclosed construction, cause the air quantity of input to be discharged by the output air port fully, because the input air channel becomes 90 to 100 ° angle with the output air channel, descending from the air quantity major part of output air port discharge again, the air quantity that the small part horizontal direction spreads is under the domatic effect of blower fan plate washer, be forced to descending, thereby carry out heat exchange through evaporimeter.This structure has not only improved the input air quantity, has also greatly improved fan efficiency simultaneously, causes discharge quantity of fan to strengthen greatly, and the evaporator surface cold is fully spread, and refrigeration improves.
Below in conjunction with accompanying drawing the utility model is done an explanation.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is a partial sectional view of the present utility model.
Blower fan 1 is the drum-type blower fan, one input air port 2 is arranged, output air port 3, complete closed except that leaving this ventilation gateway, close blower fan 1 part of blower fan plate washer 4 is reduced to the part near evaporimeter 6, referring to Fig. 2 through one domatic 5, the input air channel becomes 90 ° of angles with the output air channel, and input air port 2 is greater than output air port 3.
Claims (4)
1, circulating fan structure in a kind of refrigerator, it is made up of blower fan plate washer, blower fan and evaporimeter, and wherein blower fan and all in blower fan plate washer back, is characterized in that blower fan is the closed cylinder formula blower fan that the input air port is only arranged and export the air port on evaporimeter.
2, circulating fan structure in the refrigerator according to claim 1 is characterized in that the input air channel of blower fan becomes 90 ° to 100 ° angles with the output air channel.
3, circulating fan structure in the refrigerator according to claim 2, the input air port that it is characterized in that blower fan is greater than the output air port.
4, circulating fan structure in the refrigerator according to claim 3, the close blower fan part that it is characterized in that the blower fan plate washer is through domatic reducing near evaporator section.
