Abstract
The invention discloses a return air device for a refrigerator. The return air device comprises return air inlet plates which are arranged on the side of a refrigerating chamber and the side of a freezing chamber, and a return air inlet channel which is formed between the two side return air inlet plates, wherein the return air inlet plates are distributed vertically; a plurality of partition plates are arranged on the connection part between the two return air inlet plates; every two partition plates are arranged in parallel; and the bottom edge of an upper partition plate, which is positioned on the inner side of the section of a return air inlet of the freezing chamber, is lower than the adjacent top edge of a lower partition plate, which is positioned on the inner side of the section of a grid at one end of the refrigerating chamber, in the horizontal direction. The return air device for the refrigerator is high in foaming fluidity and can effectively prevent air from flowing back.
Description
Technical field
The present invention relates to a kind of household electrical appliance refrigerator, relate in particular to a kind of refrigerator and use air-returning device.
Background technology
Refrigerator air duct system design at present, normally the return air of appointment is regional on the evaporimeter cover plate, and some rectangular openings that evenly distribute are as return air inlet; What adopted at present is the foam quality, because expanding foam solution is relatively poor in the foam element surface mobility, causes foaming inhomogeneous; Can influence the refrigerating efficiency of refrigerator, and foam element very easily damages, and simple rectangular configuration; Be prone to cause the backflow of gas, make refrigerating chamber air flow refrigerating chamber.And the sectional area that has seriously limited return air inlet is big or small, and then reduces the refrigerating efficiency of refrigerator.
Summary of the invention
To above-mentioned defective, the invention discloses a kind of refrigerator and use the air-returning device structure, adopt polystyrene material one-body molded, can prevent effectively that air from refluxing, increasing the expanding foam solution flowability.
In order to reach above-mentioned specification requirement; The invention discloses a kind of refrigerator and use the air-returning device structure; It is by the return air oralia that is arranged on refrigerating chamber and refrigerating chamber side; Described refrigerating chamber side return air oralia is provided with the air return grille screen, and the return air grid on the described air return grille screen is the venetian blind type structure, the inboard beveling in the cross section of each return air grid.Described air return grille screen and return air oralia are one-body molded.
The return air oralia of refrigerating chamber and refrigerating chamber is vertically upright to arranging; The junction is provided with dividing plate between the two return air oralias; Described dividing plate laterally arranges in twos, wherein is positioned at inboard base, the cross section of return air grid of refrigerating chamber is positioned at an end of refrigerating chamber in the horizontal direction a little less than next piece dividing plate the inboard top margin in cross section of grid.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is carried out the detail analysis explanation.
A kind of refrigerator is used air-returning device; Comprise the return air oralia 5 that is arranged on refrigerating chamber 9 and refrigerating chamber 8 sides; Described refrigerating chamber 9 side return air oralias 5 are provided with air return grille screen 6, and the return air grid 7 on the described air return grille screen 6 is the venetian blind type structure, the inboard beveling in the cross section of each return air grid.Described air return grille screen 6 and the 5 integration mold moulding of return air oralia.Air return grille screen and return air oralia are cast as one, the problem that screen comes off can take place, and need not open the template of screen in addition, reduced production cost.
This air-returning device has adopted polystyrene material, is a kind of thermoplastic.Gloss and transparency are better, and expanding foam solution is better in the return air inlet surface mobility, can not occur foaming inhomogeneous and then influence the situation of the refrigerating efficiency of refrigerator, and polystyrene material is not fragile, and product quality increases.
Adopt cell structure can prevent effectively that foreign matter from stopping up refrigerating chamber 9 side return air inlets, cell structure is not set, can preferably gas be derived at the return air inlet of refrigerating chamber 8 sides.With the inboard beveling in each return air grid cross section, return air inlet forms spatial arrangement and side air admission, in the return air zone that is limited, increases the return air inlet sectional area as much as possible, thereby can reduce the resistance of wind cyclic process effectively, improves the refrigerating efficiency of refrigerator.
It is vertically upright to arranging with the return air oralia 5 of refrigerating chamber 8 sides to be arranged on refrigerating chamber 9; Be tiltedly installed with dividing plate between the two return air oralias 5; Described dividing plate laterally arranges in twos; The end that each dividing plate is positioned at refrigerating chamber 9 is higher than an end of refrigerating chamber 8, and an end that guarantees to be positioned at the first inboard dividing plate 1 of the cross section of refrigerating chamber 8 return air inlets is positioned at the inboard end in cross section of refrigerating chamber 9 grids in the horizontal direction a little less than second partition 2; An end that is positioned at the inboard second partition 2 in the cross section of refrigerating chamber 8 return air inlets is in the horizontal direction a little less than an end of the 3rd inboard dividing plate 3 of the cross section that is positioned at refrigerating chamber 9 grids; When cold air occurs to refrigerating chamber 9 backflow situation; The difference in height that exists owing to dividing plate; So can stopping cold air, the higher dividing plate of refrigerating chamber 9 side relative positions continues to flow to refrigerating chamber 9; Said structure can prevent effectively that refrigerating chamber 8 air from refluxing to refrigerating chamber 9, and the centre is provided with dividing plate, can flow to refrigerating chamber 8 from refrigerating chamber 9 by effective guidance gas.
