Embodiment Construction

[0034] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0035] In the present invention, a cross-flow fan is used as a gas conveying machine in an air duct of an air-cooled refrigerator to replace a conventional axial-flow fan or a centrifugal fan.

[0036] Such as figure 2 and image 3 The shown air-cooled refrigerator consists of a freezer or refrigerator 1, an air inlet 2 leading to the freezer or refrigerator 1 and a return air outlet 7, a cross-flow fan 5, an air duct 12, an evaporator 6, and a compressor 8. . The cross-flow fan 5 is installed on the top of the air duct 12, below the air inlet 2, a volute 4 is arranged on the air duct 12 inside the cross-flow fan 5, and a volute 3 is arranged on the air duct 12 outside the cross-flow fan 5 . The direction of the fan motor shaft in the present invention is different from that of the original refrigerator. The original motor shaft is perpendi...

Abstract

An airflow circulating system for refrigerator comprises an air delivering apparatus, an air inlet and an air duct, the air delivering apparatus is an cross flow fan which is arranged on the upper part of the air duct and on the lower part of the air inlet, a volute tongue is provided on the air duct of the inner side of the cross flow fan, a volute casing is provided on the air duct of the outer side of the cross flow fan; the shaft line of the cross flow fan can be perpendicular to the lateral face of the refrigerator, the rotation direction of the cross flow fan directs to the air inlet; the volute casing is big arc-shaped and spiral line-shaped, the tip terminal shape of the volute tongue is circular arc-shaped; the cross flow fan comprises 2-6 impellers; each impeller comprises n blades with different centre angles and end sheets; the neighboring impellers are staggered with a certain angle along the circumferential direction. The airflow circulating system can be used for an wall hanging type air conditioner indoor set, an air curtain machine, an air heater and a dehumidifier. The invention has low flowing noise, is easy to be deposited inside of the air duct, can greatly reduce the refrigerator air duct dimension when applied to the refrigerator, thereby improving the refrigerator volume.

Description

technical field [0001] The invention relates to an airflow conveying device, especially a cold air circulation system applicable to a refrigerator. Background technique [0002] The air-cooled refrigerator transports the cold air obtained in the refrigeration cycle to the freezer or refrigerator through the air circulation fan in the air duct to cool the food or prevent the food from going bad. [0003] Although different air-cooled refrigerator models have their own air supply methods, the current air-cooled refrigerator gas delivery devices can be summarized into two types: [0004] One is the axial flow fan, which has the characteristics of low pressure and large air volume, and is widely used in refrigerator air ducts. The gas particles basically flow along the cylindrical surface with the rotating shaft as the center, and there is a pressure difference between the blade end and the root, and backflow will occur at the root, thereby affecting the flow performance in the...
