Description
Technical field
The utility model relates to a kind of refrigerating chamber air channel structure, relates in particular to a kind of cold compartment of refrigerator air channel structure that is applied in the indirect cool refrigerator, belongs to household electrical appliance technical field.
Background technology
Comparatively common in the market indirect cool refrigerator, the cooling procedure of its refrigerating chamber is as follows mostly: the passage of the cold air of refrigerating chamber in case is sent to refrigerating chamber air channel inlet, and wind path is generally from the air-out of refrigerating chamber top.For this reason, be positioned at the lower layer space of refrigerating chamber, mainly rely on cold air free convection, sink to cooling off, cause the temperature difference of refrigerating chamber layering bigger easily, be unfavorable for storing the fresh-keeping of food.Simultaneously, duct cross-section is long-pending less at present, causes the wind path on-way resistance bigger, has both influenced the refrigerating efficiency of refrigerator, causes the waste of the energy again easily.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of cold compartment of refrigerator air channel structure is provided.
The purpose of this utility model realizes by following technical solution:
The cold compartment of refrigerator air channel structure, relate to cold compartment of refrigerator, this structure comprises duct shield, air channel heat insulation layer, electronic damper, air inlet, and duct shield is distributed in the refrigerating chamber, is distributed with air outlet on the duct shield, be provided with the air channel heat insulation layer in the duct shield, one end of air channel heat insulation layer is provided with electronic damper, and electronic damper is provided with air inlet, wherein: be provided with interlayer in the refrigerating chamber, the distribution of the corresponding interlayer of the distribution of air outlet, and the air channel heat insulation layer is provided with at least two wind path passages independently each other.
The purpose of this utility model also can further realize by following technical measures:
Above-mentioned cold compartment of refrigerator air channel structure, wherein, the cross section of described wind path passage is a circular arc.
Further, above-mentioned cold compartment of refrigerator air channel structure wherein, respectively is provided with independently projection between described two wind path passages.
Again further, above-mentioned cold compartment of refrigerator air channel structure, wherein, described duct shield end is connected with return air inlet.
Advantage of the present utility model is: after adopting the utility model, cold air can be by the guiding of each air outlet, fully be distributed in each interlayer of refrigerating chamber, make the interlayer that is positioned at the refrigerating chamber bottom can access sufficient refrigeration equally, and do not rely on cold air free convection, sinking at needs, guaranteed the bigger temperature difference can not occur between the refrigerating chamber layering, helped storing the fresh-keeping of food.Therefore this cold compartment of refrigerator air channel structure has good application prospects in the manufacturing and the use field of indirect cool refrigerator, is worthy to be popularized.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

The specific embodiment
Cold compartment of refrigerator air channel structure shown in Fig. 1～3, relate to cold compartment of refrigerator, this structure comprises duct shield 1, air channel heat insulation layer 2, electronic damper 3, air inlet 4, duct shield 1 is distributed in the refrigerating chamber, be distributed with air outlet 8 on the duct shield 1, be provided with air channel heat insulation layer 2 in the duct shield 1, one end of air channel heat insulation layer 2 is provided with electronic damper 3, after electronic damper 3 is opened, wind enters the air channel by the air inlet 4 of heat insulation layer lower end, its unique distinction is: be provided with interlayer in the refrigerating chamber, and the distribution of the corresponding interlayer of the distribution of air outlet 8, and air channel heat insulation layer 2 is provided with at least two wind path passages independently each other.Done optimization at duct cross-section square in the prior art, the cross section of described wind path passage is a circular arc.Simultaneously, between described two wind path passages, respectively be provided with independently projection 5, both helped the independent air feed of wind path passage, can be convenient to air channel heat insulation layer 2 again and be assembled in the refrigeration inner bag groove, carry out further fixing.Moreover, be connected with return air inlet 7 at duct shield 1 end, help the circulating reflux of cold air.
The concrete course of work of this cold compartment of refrigerator air channel structure is as follows: after refrigerator came into operation, when refrigerating chamber need freeze, electronic damper 3 was opened, and wind enters the refrigeration air channel by air inlet, even flow in heat insulation layer with cold air.Then, cold air is blown out to each interlayer of refrigerating chamber by each air outlet 8, gets back to refrigerating chamber from return air inlet 7 at last.In conjunction with structure of the present utility model further, by refrigerating chamber shelf 6 refrigerating chamber is separated into several interlayers, all be distributed with air outlet 8 at each interlayer, guarantee the air quantity uniform distribution between each interlayer when refrigerating chamber freezes, so spatial temperature distribution is also more even than the refrigerating chamber that adopts former air channel structure.Again further combined with Fig. 3 air channel heat insulation layer 2, rely on projection 5 that wind path is divided into two-way.Depend on the wind path passage of circular cross-section, make sectional area maximization and cross section and make girth minimize, reduced the on-way resistance of air channel heat insulation layer 2 inner wind paths.
This shows, after adopting the utility model, cold air can be by the guiding of each air outlet 8, fully be distributed in each interlayer of refrigerating chamber, make the interlayer that is positioned at the refrigerating chamber bottom can access sufficient refrigeration equally, and do not rely on cold air free convection, sinking at needs, and guaranteed can not occur between the refrigerating chamber layering the bigger temperature difference, help storing the fresh-keeping of food.Therefore this cold compartment of refrigerator air channel structure has good application prospects in the manufacturing of indirect cool refrigerator and practical field, is worthy to be popularized.
Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
