Abstract
The invention discloses a refrigerator which comprises a refrigerator body provided with an inner refrigerating compartment, an air duct, and an air return passage. The refrigerator body comprises a partition which divides the refrigerating compartment into a freezing chamber and a refrigerating chamber below the freezing chamber. The air duct is arranged on the rear wall of the freezing chamber. The air return passage is formed on the partition. A first end of the air return duct is communicated with the refrigerating chamber, and a second end of the air return passage is communicated with the air duct. The partition comprises a cover plate and a bottom plate below the same. The cover plate is connected with the bottom plate to form the air return passage. The cover plate is not smaller than 35Kg/m<3> in density and not smaller than 25mm in thickness. Interference of the freezing chamber of the refrigerator upon the return air passage is avoided, and vapor in return air is prevented from condensing and icing.
Description
Technical field
The present invention relates to field of domestic appliances manufacture technology, particularly relate to a kind of refrigerator.
Background technology
Could cook after the freezing meat of direct cooling refrigerator need thaw at present, and refrigerating chamber will manually defrost at set intervals.Allegro life, particularly city young people more and more tend to use frost-free refrigerator, or with soft freezing refrigerator.And the design rationality of air channel structure in the middle of the particularity of frost-free refrigerator properity, particularly frost-free refrigerator is determining that the performance of frost-free refrigerator is good and bad.
The unicity of past frost-free refrigerator exit region, the unicity of category, and the unicity of product structure be not so that the design in air channel considers in the middle of the frost-free refrigerator.Along with refrigerator uses the expansion in zone, the environment for use of different regions, the occupation mode of different user, otherness is larger.If the middle Duct design of frost-free refrigerator is unreasonable, in improper use, or the abominable situation of service condition, risk can appear stopping up in the air channel.
There is following shortcoming in the air channel in the middle of the industry frost-free refrigerator at present:
1. so that air-return duct is subjected to the cooling influence of refrigerating chamber, there are the hidden danger of freezing in middle air duct cover board density, thickness deficiency.
2. middle air channel air-return duct gradient design is unreasonable, has the defrosting water deposition, causes icing hidden danger.
In fact; more than 2 be interactional; when air duct cover board density low (the highest 30Kg of industry standard is every cubic metre at present), thickness deficiency; " warm braw " of refrigerating chamber is subjected to the cooling influence of refrigerating chamber in air-return duct; stopped status particularly; so that in the air-return duct " condensation "; because air-return duct and refrigerating evaporator are near the position plane design; or the gradient design is unreasonable; the globule is cumulative in air-return duct; the final air-return duct that stops up, so that refrigerating chamber cold wind can not form recurrent state, temperature of refrigerating chamber can not satisfy instructions for use.
Simultaneously, middle air channel air-return duct gradient design is unreasonable, when the defrosting water of evaporimeter in the household freezer is splashed in the air-return duct, can not in time evaporate, drain, and causes deposition, finally causes icing hidden danger;

Describe refrigerator according to the embodiment of the invention in detail below with reference to accompanying drawing.
As depicted in figs. 1 and 2, the refrigerator according to the embodiment of the invention comprises: casing 10, air channel 103 and return air channel 104.
Specifically, has chamber 101 between refrigeration in the casing 10.Casing 10 comprises that dividing plate 102 is divided into refrigerating chamber 1011 and is positioned at refrigerating chamber 1011 times the refrigerating chamber 1012 of (namely as shown in fig. 1 below) face with chamber 101 between will freezing.
Air channel 103 is located at the rear wall (namely as shown in fig. 1 the left side of refrigerating chamber 1011) of refrigerating chamber 1011.
Wherein, dividing plate 102 comprises cover plate 1021 and is positioned at base plate 1022 below the cover plate 1021.Cover plate 1021 links to each other to consist of return air channel 104 with base plate 1022.The density of cover plate 102 is 〉=35Kg/m
3And the thickness 〉=25mm of cover plate 102.Advantageously, the thickness of cover plate 102 is 28mm.
According to the refrigerator of the embodiment of the invention, the cover plate density of return air channel is 〉=35Kg/m
3And the thickness 〉=25mm of cover plate has avoided the cold of refrigerating chamber to the interference effect of return air channel, the hidden danger of having avoided the steam condensation in the return air to freeze.
As shown in Figure 2, according to an example of the present invention, return air channel 104 comprises the first passage section 1041 that is obliquely installed and the second channel section 1042 that is positioned at first passage section 1041 left sides.Advantageously, return air channel 104 is configured to substantially splayed.Further, the gradient of first passage section 1041 and second channel section 1042 all 〉=6 is spent.Advantageously, the gradient of first passage section 1041 is that the gradient of 8 degree and second channel section 1042 is 7.5 degree.Thus, when return air channel 104 " condensation " water occurred or is splashed into defrosting water, " double inclined plane " structure of first passage section 1041 and second channel section 1042 can in time be drained " condensation " water, defrosting water.
According to an example of the present invention, the length of first passage section 1041 is greater than the length of second channel section 1042.Advantageously, the peak of cardinal principle splayed return air channel 104 and the distance 〉=50mm in air channel 103.Further, the peak of splayed return air channel 104 and the distance in air channel 103 are 55mm substantially.That is to say that second channel section 1042 is 55mm with the distance in air channel 103.Thus, can avoid the defrosting water in the air channel 103 owing to be splashed in the return air channel 104, and, even be splashed into defrosting water, can in return air channel 104, not accumulate yet.
According to the refrigerator of the embodiment of the invention, the cover plate density of return air channel 104 is 〉=35Kg/m
3And the thickness 〉=25mm of cover plate can avoid the cold of refrigerating chamber to the interference effect of return air channel 104, has avoided icing hidden danger.And return air channel 104 adopts double inclined surface structures, and the defrosting water that can in time discharge condensed water or be splashed into is avoided condensed water or the defrosting water that is splashed into accumulates in return air channel 104, has further avoided icing hidden danger.According to the refrigerator of the embodiment of the invention, reasonable in design.Verification msg is surperficial fully, though worst service condition, such as high humidity, the market, South America that temperature is high, perhaps Association of South-east Asian Nations market arranges temperature control under the use habit of maximum, and refrigerator still can work, and can not occur the hidden danger of freezing in the return air channel.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although the above has illustrated and has described embodiments of the invention, be understandable that, above-described embodiment is exemplary, can not be interpreted as limitation of the present invention, those of ordinary skill in the art can change above-described embodiment in the situation that does not break away from principle of the present invention and aim within the scope of the invention, modification, replacement and modification.
