Abstract
A kind of return air device for refrigerator, comprise the return air oralia, the return air inlet passage between the return air oralia of both sides that are arranged on refrigerating chamber and refrigerating chamber side, described return air oralia vertically stands to arrangement, between two return air oralias, junction is provided with some dividing plates, dividing plate be arranged in parallel between two, base inside the cross section that wherein adjacent upper baffle is positioned at the return air inlet of refrigerating chamber is positioned at the top margin inside the cross section of the grid of one end of refrigerating chamber in the horizontal direction lower than underlay screen, this device foaming good fluidity and effectively prevent the backflow of gas.
Description
Technical field
The present invention relates to a kind of household electrical appliance refrigerator, particularly relate to a kind of return air device for refrigerator.
Background technology
Current air duct system for refrigerator design, the return air region of normally specifying on evaporimeter cover plate, be uniformly distributed some rectangular openings as return air inlet, currently used is froth texture, because expanding foam solution is poor in foam element surface mobility, cause foaming uneven, can affect the refrigerating efficiency of refrigerator, and foam element very easily damages, and simple rectangular configuration, easily cause the backflow of gas, make refrigerating chamber air flow refrigerating chamber.And seriously limit the sectional area size of return air inlet, and then reduce the refrigerating efficiency of refrigerator.
Summary of the invention
For above-mentioned defect, the invention discloses a kind of return air device for refrigerator structure, adopt polystyrene material one-body molded, effectively can prevent air return, increase expanding foam solution mobility.
In order to reach above-mentioned technical requirement, the invention discloses a kind of return air device for refrigerator structure, it is by the return air oralia being arranged on refrigerating chamber and refrigerating chamber side, described refrigerating chamber side return air oralia is provided with air return grille screen, return air grid on described air return grille screen is venetian blind type structure, beveling inside the cross section of each return air grid.Described air return grille screen and return air oralia one-body molded.
The return air oralia of refrigerating chamber and refrigerating chamber vertically stands to arrangement, between two return air oralias, junction is provided with dividing plate, described dividing plate be arranged in parallel between two, and the base inside the cross section being wherein positioned at the return air grid of refrigerating chamber is positioned at the top margin inside the cross section of the grid of one end of refrigerating chamber in the horizontal direction a little less than next block dividing plate.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed analytic explanation is carried out to the present invention.
A kind of return air device for refrigerator, comprise the return air oralia 5 being arranged on refrigerating chamber 9 and refrigerating chamber 8 side, described refrigerating chamber 9 side return air oralia 5 is provided with air return grille screen 6, and the return air grid 7 on described air return grille screen 6 is venetian blind type structure, beveling inside the cross section of each return air grid.Described air return grille screen 6 is shaping with return air oralia 5 integration mold.Air return grille screen and return air oralia are cast as one, the problem that screen comes off can not occur, and separately need not open the template of screen, reduce production cost.
This air-returning device have employed polystyrene material, is a kind of thermoplastic.Gloss and transparency are better, and expanding foam solution is better in return air inlet surface mobility, and there will not be foaming uneven and then affect the situation of refrigerating efficiency of refrigerator, and polystyrene material is not fragile, product quality increases.
Adopt cell structure effectively can prevent foreign matters from being blocked refrigerating chamber 9 side return air inlet, at the return air inlet of refrigerating chamber 8 side, cell structure is not set, can preferably gas be derived.By beveling inside each return air grid cross section, return air inlet forms spatial arrangement and side air admission, in limited return air region, increases return air inlet sectional area as much as possible, thus effectively can reduce the resistance of wind cyclic process, improve the refrigerating efficiency of refrigerator.
Be arranged on refrigerating chamber 9 vertically to stand to arrangement with the return air oralia 5 of refrigerating chamber 8 side, dividing plate is tiltedly installed with between two return air oralias 5, described dividing plate be arranged in parallel between two, each dividing plate is positioned at one end higher than refrigerating chamber 8, one end of refrigerating chamber 9, and ensures that the one end of the first dividing plate 1 be positioned at inside the cross section of refrigerating chamber 8 return air inlet is positioned at the one end inside the cross section of refrigerating chamber 9 grid in the horizontal direction a little less than second partition 2; The one end of second partition 2 inside the cross section being positioned at refrigerating chamber 8 return air inlet is in the horizontal direction a little less than one end of the 3rd dividing plate 3 inside the cross section being positioned at refrigerating chamber 9 grid; When cold air occurs refluxing situation to refrigerating chamber 9, difference in height is there is due to dividing plate, relative position higher dividing plate in refrigerating chamber 9 side continues to flow to refrigerating chamber 9 so can stop cold air, described structure can effectively prevent refrigerating chamber 8 air from refluxing to refrigerating chamber 9, centre is provided with dividing plate, can effectively guide gas to flow to refrigerating chamber 8 from refrigerating chamber 9.
