Accompanying drawing explanation
Fig. 1 is the structural representation of the refrigerator inside of prior art;
Fig. 2 is the structural representation of first embodiment of the invention.
The realization of the object of the invention, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of refrigerator air duct.
With reference to Fig. 1, Fig. 1 is the structural representation of the first embodiment of the present invention, in the present embodiment, the casing 100 that this refrigerator air duct 200 is arranged at refrigerator is inner, it comprises exhaust passage 210 and air-return duct 220, described exhaust passage 210 is provided with air outlet 211, described air-return duct 220 is provided with return air inlet 221; The evaporimeter (not shown) of described refrigerator produces cooling air after heat exchange process, and described cooling air is sent to described casing 100 by described air outlet 211; Cooling air in described casing 100 is back to described evaporimeter by described return air inlet 221 and carries out heat exchange process.
Particularly, this air-return duct 220 is communicated with the heat exchange entrance of evaporimeter, the heat exchange outlet of exhaust passage 210 and evaporimeter; Air in casing 100 is back to air-return duct 220 by return air inlet 221, and flow to the heat exchange entrance of evaporimeter, cooling air is formed after heat exchange process in evaporimeter, this cooling air to the exhaust passage 210 of refrigerator, and flows out in casing 100 by air outlet 211 by the heat exchange outlet flow of evaporimeter, thus, recuperated cycle is produced in refrigerator, during refrigerator normal operation, cooling air endlessly will be produced, for carrying out fresh-keeping and cold storage to the article be stored in refrigerator.
This casing 100 comprises the back side wall 110, the dividing plate 140 for placing articles that arrange corresponding to chamber door, casing 100 also comprises left side wall 120 for supporting clapboard 140 and right-side wall 130, thus dividing plate 140 is positioned at casing 100 centre that back side wall 110, left side wall 120, right-side wall 130 and chamber door enclose, the visual real needs of quantity of dividing plate 140 arrange several, and concrete number is in this no limit; Described refrigerator air duct 200 is arranged in described back side wall 110, and has gap between described refrigerator air duct 200 and described dividing plate 140.Thus the return air inlet 221 tradition is arranged on inner container of icebox, move on refrigerator air duct 200, be arranged in the back side wall 110 in casing 100 due to refrigerator air duct 200, between itself and the article being positioned in refrigerator, there is certain distance, thus can effectively avoid the article placed in refrigerator to block return air inlet 221, thus the recuperated cycle process in refrigerator is carried out smoothly, refrigerator is operated more smooth and easy, refrigerating fresh-keeping effect promoting.
Further, described return air inlet 221 is several, and scattering device is on described air-return duct 220.
The scattering device of return air inlet 221, when the article being positioned over dividing plate 140 are more, the situation of certain return air inlet 221 of blocking may be there is, now, because return air inlet 221 is provided with multiple, and scattering device is on air-return duct 220, then each return air inlet 221 can not be simultaneously blocked, air then in casing 100 is back to evaporimeter by not blocked return air inlet 221, and continuity recuperated cycle process, ensures that the process of refrigerastion of refrigerator is smooth and easy and carry out.
Further, described refrigerator air duct 200 is detachably installed in described back side wall 110.
Refrigerator air duct 200 is arranged in back side wall 110 as independent part detachable, when needs carry out the cleanings such as defrost to refrigerator air duct 200, refrigerator air duct 200 can be disassembled and clear up, handled easily; And when refrigerator air duct 200 or evaporimeter break down, also refrigerator air duct 200 can be dismantled and replace or maintenance, be conducive to recycling of refrigerator.
Further, described exhaust passage 210 and air-return duct 220 are separated and are arranged, and described exhaust passage 210 is arranged around described air-return duct 220.
Particularly, in the present embodiment, air-return duct 220 arranges the center with whole refrigerator air duct 200, and exhaust passage 210 is arranged at the both sides of air-return duct 220 and is communicated with, thus in refrigerator, produce air swirl flowing, is conducive to the air return in refrigerator; And exhaust passage 210 is looped around the both sides of air-return duct 220, the air themperature being back to evaporimeter can be made to reduce, thus be conducive to the power consumption reducing evaporimeter, be conducive to energy-conservation.
Further, the end 222 of described air-return duct 220 reduces gradually along the sectional area of described air-return duct 220 length direction.
The end 222 of air-return duct 220 presents arc surfaced, and be conducive to the air flowing in exhaust passage 210, can not cause the empty air turbulence in exhaust passage 210 because of sharp-pointed corner angle, thus air-out is smooth and easy, refrigeration is better.
Further, described air outlet 211 is several, and array arrangement is on described exhaust passage 210.
Air outlet 211 ordered arrangement is in the both sides of exhaust passage 210, and air outlet 211 is preferably strip opening, then also not easily stopped during air-out, cooling air slowly flows out in casing 100 in proper order, one large strand of cooling air is avoided directly to blow to certain, and freezing food.
Further, described refrigerator air duct 200 is one-body molded.
This refrigerator air duct 200 can be one-body molded by plastic material, is suitable for producing in enormous quantities, improves and manufacture efficiency, reduces production cost.
The present invention also provides a kind of refrigerator, and this refrigerator comprises casing, and casing is provided with refrigerator air duct, and the structure of this refrigerator air duct, operation principle and the beneficial effect that brings, all with reference to the description of above-described embodiment, do not repeat them here.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
