Integral-type air-supplying-returning device and air-cooling refrigerator with integral-type air-supplying-returning device

Abstract

The invention provides an integral-type air-supplying-returning device and an air-cooling refrigerator with the integral-type air-supplying-returning device. The integral-type air-supplying-returning device comprises an air inlet pipe and a first air returning pipe. The air inlet pipe is provided with a cold air inlet, a first air outlet and a main channel between the cold air inlet and the first air outlet, and formed by a first cover and a second cover, wherein the first cover and the second cover are in sealing connection in a buckled mode. The first air returning pipe is provided with a first air returning inlet, a first air returning outlet and a first air returning channel between the first air returning inlet and the first air returning outlet. The integral-type air-supplying-returning device is easy to assemble, and the integral-type air-supplying-returning device is supplied in an assembly mode in practical production; before foaming is carried out, the integral-type air-supplying-returning device is arranged at the back of an inner container of a refrigerator body in advance, the storage volume of the refrigerator is not occupied, and the object storage space is increased. In addition, the first cover and the second cover of the air inlet pipe are sealed and fastened together in the buckled mode, no screw is required, the sealing structure is simple, foaming liquor is prevented from entering the sealing structure, the strength is good, installation is convenient to achieve, and multi-temperature-zone control over the refrigerator is achieved.

Description

technical field [0001] The present invention generally relates to the field of refrigerators, and more specifically, relates to an integrated air supply and return device and an air-cooled refrigerator including the device. Background technique [0002] Compared with direct cooling refrigerators, air-cooled refrigerators have gradually been used due to their advantages of frost-free and uniform cooling. Existing air-cooled refrigerators generally all are to suck cold air from the evaporator by the fan, and then distribute it to each compartment through the air duct. The used air supply and return air device has a complex structure and many parts are required, especially the polystyrene (EPS) foam has a complex structure and a complicated sealing process, which has poor sealing performance and is fragile during transportation. In addition, the air outlets of the air-conditioning in the compartment are relatively concentrated, which are easily blocked by the food piled up in ...

AI Technical Summary

Problems solved by technology

The structure of the air supply and return device used is complex and requires many parts, especially the polystyrene (EPS) foam structure is complex and the sealing process is complicated, the sealing is poor, and it is fragile during transportation

In addition, the air-conditioning outlets in the compartment are relatively concentrated, which are easily blocked by the food piled up in the compartment, resulting in poor air circulation and uneven temperature in the compartment, so that the utilization rate of the refrigerator’s air-conditioning is low.

As a result, the operating time of the compressor will be correspondingly extended, resulting in high energy consumption and high noise of the product
