Technical solution problem of the present invention adopts following technical scheme:
The design feature of a kind of refrigerator air flue structure of the present invention is: air channel is set is in the same perpendicular being in evaporimeter place, comprise, be fixedly installed a face shield at evaporimeter towards a side of refrigerator compartment, the sidepiece that described face shield fits in evaporimeter forms evaporator chamber, described face shield extends to flow passage side plate at an upper portion thereof, runner is positioned at the back of described flow passage side plate, and circulating fan is in evaporimeter top and jointly collects with runner the back that is contained in flow passage side plate; Duct outlet lays respectively at top and the bottom of flow passage side plate, and air channel return air inlet is positioned at the bottom of evaporator chamber.
The design feature of refrigerator air flue structure of the present invention is also: described face shield extends to return air deflector in bottom, and the return air of refrigerator compartment imports return air inlet by return air deflector.
The feature of a kind of refrigerator of the present invention is the refrigerator air flue structure described in the above-mentioned arbitrary feature of employing.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is by being combined into motor, fan and runner a compact component, union is contained in the formation air channel, top of evaporimeter, realize refrigerator compartment inner air convection and evaporator surface exchange heat by duct outlet and air channel return air inlet, not only increase the cubical content of refrigerator compartment, save the required refrigerator cost of corresponding volume, can also effectively improve the energy efficiency of refrigeration for refrigerator.
2, the set air channel of the present invention has still retained multi-air outlet in saving refrigerator inside space, has ensured the uniformity of the circularly cooling effect of refrigerator compartment temperature.

Detailed description of the invention
In the present embodiment, as shown in Figure 3 and Figure 4, a kind of refrigerator air flue structure is, it is to be in the space forming with the same perpendicular at evaporimeter 2 places that air channel is set, comprise, be fixedly installed a face shield 10 at evaporimeter 2 towards a side of refrigerator compartment 1, the sidepiece that face shield 10 fits in evaporimeter forms evaporator chamber, face shield 10 extends to flow passage side plate 9 as shown in Figure 8 at an upper portion thereof, runner is positioned at the back of flow passage side plate 9, and the circulating fan being made up of motor 6 and fan 7 is in evaporimeter 2 tops and jointly collects with runner the back that is contained in flow passage side plate 9; Runner is not established in the dead ahead of evaporimeter 2, thereby take full advantage of the space of evaporimeter 2 tops, save the volume that existing air channel runner is arranged on the occupied refrigerator compartment depth direction in evaporimeter 2 fronts, as shown in Figure 5,4 duct outlets 11 lay respectively at top and the bottom of flow passage side plate 9, as shown in Figure 7, air channel return air inlet 12 is positioned at the bottom of evaporator chamber.
In concrete enforcement, as shown in Figure 6, extend return air inlet and return air deflector 13 are set in bottom at face shield 10, the return air of refrigerator compartment 1 imports air channel return air inlet 12 by return air deflector 13.
Adopt a refrigerator for above-mentioned refrigerator air flue structure, in the process in assembling air channel, first flow passage side plate 9, motor 6 and fan 7 are fitted together by shown in Fig. 9; Then by shown in Fig. 6, flow passage side plate 9 is placed on face shield 10 after, flow passage side plate 9 is corresponding rear mutually to being stuck with buckle and the slotted eye position of face shield 10, locate drivescrew respectively at two screw holes (being 14a and the 14b in Fig. 7 and Fig. 8) at the back side of flow passage side plate 9 again, flow passage side plate 9 is fixed on face shield 10, thereby is assembled into air channel as shown in Figure 6; Evaporimeter 2 is contained in liner 3 rears, adopts buckle to fix and the fixing screw hole 15 of two side positions of flow passage side plate 9 () is each in the left and right sides, middle and upper part of face shield 10 plays a screw and be used for strengthening fixing between air channel and liner 3.
As shown in Figure 3, operation principle of the present invention forms negative pressure by circulating fan above evaporimeter 2, high pressure cold in runner enters chamber 1 between refrigeration for refrigerator by exhaust passage air outlet 11, because runner is above evaporimeter, flow passage route is relatively short, air-flow can obtain initial velocity faster while entering the top of chamber 1 between refrigeration, air-flow indoor between being conducive to mixes and exchange heat, the air-flow carrying out after heat exchange enters evaporator surface by return air deflector 13 from the air channel return air inlet 12 of bottom, thereby realizes cross-ventilation and exchange heat in refrigerator.
As shown in Figure 5, air channel adopts multi-air outlet to distribute, and flow path groove on flow passage side plate 9 adopts the design of streamlined guiding gutter, as shown in Figure 8, runner is because of the design feature of streamlined guiding gutter and mate suitable fan, after assembling, can comparatively reasonably carry out cold wind distribution, and airflow circulating more rationally effectively, be easier to heat and fully exchange, promoted the energy efficiency of refrigerator; And the uniformity of refrigeration for refrigerator compartment temperature is guaranteed.
