Refrigerator

Abstract

The present invention relates to one refrigerator. In the aspiration channel of the back pipeline, one integral deodorizing device comprising special deodorizing fan and deodorizing catalyst is set to ensure the wind rate passing through the deodorizing catalyst. The present invention has raised deodorizing performance of the cold storage chamber while saving space and maintaining the beautiful appearance.

Description

technical field [0001] The present invention relates to piping for cooling the interior of a refrigerator. Background technique [0002] In recent years, due to the diversification of lifestyles, the quality of the design greatly affects the value of the product, so people have been trying to improve the appearance of the refrigerator (see, for example, JP-A-8-152254). For a long time, people have a lot of potential dissatisfaction with the bad smell in the refrigerator. In order to ensure the space in the refrigerator and improve the deodorization performance, it is sometimes necessary to set a deodorization filter in the pipeline for cooling the inside of the refrigerator (for example, refer to JP-P-5 - Bulletin No. 203336). [0003] The conventional refrigerator as described above will be described below with reference to the accompanying drawings. [0004] Fig. 8 is a plan sectional view of a refrigerator compartment of a conventional refrigerator. In FIG. 8 , a foam ...

AI Technical Summary

Problems solved by technology

[0006] But in the existing structure as shown in Figure 8, although the back of the box of the refrigerator compartment 5 is very simple, but because the back is made of the inner box, the surface material of the pipeline 6 will be exposed, and the beautiful surface cannot be shown. Gloss and transparency etc.

while in Figure 9 In the existing structure shown, the problem is that since a deodorizing filter 15 is provided on the passage section near the suction port 14 of the return pipe 13 of the refrigerator compartment, it not only makes the design of the refrigerator compartment unsightly, but also increases the number of air ducts. Resistance, so that the cooling performance of the refrigerator compartment 10 is reduced

Considering the above-mentioned problems, in order to reduce the air passage resistance of the deodorizing filter 15, there is a method of increasing the mesh size of the filter, but in this case, the contact area is reduced, so that the deodorizing performance is degraded again.

And in another method to prevent cooling performance reduction, that is, in the method of making the deodorizing filter 15 communicate with a part of the return pipe 13 of the refrigerator compartment as a branch, due to the large deodorizing filter 15 flowing into the air duct resistance If the cooling air volume is reduced, the deodorization performance will be reduced.
