Abstract
The utility model discloses a refrigerator for optimizing a cold air circulation path which comprises an evaporator(1). A return air baffle(2) is arranged on a cover plate(11) of the evaporator(1) and the upper end of the return air baffle is fixed on the cover plate(11) of the evaporator(1), the lower end of the return air baffle(2) is hung in the air, a return air inlet(3) is formed between the lower end of the return air baffle(2) and the evaporator(1). Compared with the prior art, the utility model has the effects that by adopting the return air baffle, the air circulation path is optimized, air quantity flowing around the lower drawer(4) of the refrigerator is improved, temperature difference between the lower drawer(4) and the other part of the compartment is reduced so that the temperature is more uniform, thereby the problem that the temperature of the lower drawer(4) of the traditional refrigerator is higher than that of the other compartment is resolved effectively.
Description
Technical field
The utility model relates to the technical field of refrigerator in the household electrical appliance, especially a kind of frost-free refrigerator of optimizing the cold wind circulating path.
Background technology
Ducting system design about frost-free refrigerator, one of them key point be how each chamber of reasonable distribution and each storage element of each chamber interior the conveying capacity of getable cold wind, just how to optimize the circulating path of cold wind, allow cold wind freeze for equably each storage element of each chamber, could guarantee the uniformity of each chamber interior temperature like this.
At present, the freezer compressor overwhelming majority is installed in the rear lower of refrigerator, for frost-free refrigerator, the upper edge of drawer often is in sustained height with return air inlet under the refrigerating chamber, referring to schematic diagram 3, the schematic diagram of conventional refrigerator cold wind circulating path, most of cold wind can enter return air inlet 3 along the upper edge of following drawer 4, finishes the cold wind circulation.Will cause down 4 getable cold blast rates of drawer not enough like this, temperature can be higher than other storage area of same chamber.With three-star refrigerating chamber is example, according to request of national standard, refrigerator is after reaching stable operation, the maximum temperature of any point must not be higher than-18 ℃ in the three-star refrigerating chamber, in order to meet this requirement, has only the running time that prolongs compressor, the temperature of drawer is met the requirements, and when the temperature of drawer reached-18 ℃ instantly, other space of same chamber must be cold excessively, and energy consumption also can correspondingly increase.A major reason that causes the problems referred to above is exactly that the path of wind circulation is unreasonable, and the path of reasonably optimizing wind circulation is the good method that addresses the above problem.
The utility model content
The technical problems to be solved in the utility model provides a kind of refrigerator that can optimize the wind circulating path.
For solving the problems of the technologies described above, technical scheme of the present utility model is:
A kind of refrigerator of optimizing the cold wind circulating path comprises evaporimeter, and the return air baffle plate is installed on the cover plate of described evaporimeter, and return air baffle plate upper end is fixed on the cover plate of evaporimeter, the lower end unsettled and and evaporimeter between form return air inlet.
Described return air baffle plate upper end is provided with projection, and the cover plate of evaporimeter is provided with the notch that inserts for projection.
Described return air baffle plate is provided with screw, and the relevant position also is provided with screw on the cover plate of evaporimeter, with screw the return air baffle plate is fixed on the cover plate of evaporimeter.
The utility model with respect to the beneficial effect of prior art is:
The utility model adopts the return air baffle plate, optimizes the circulating path of wind, increases the air quantity around the drawer under the refrigerator of flowing through, and the temperature difference of the other parts of drawer and this chamber makes more uniform temperature under dwindling.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the rigging position of return air baffle plate in refrigerator of the utility model refrigerator;
Fig. 2 is the schematic diagram of the utility model cold wind circulating path;
Fig. 3 is the schematic diagram of conventional refrigerator cold wind circulating path;
Fig. 4 is the scheme of installation of the utility model return air baffle plate.
The specific embodiment
Referring to Fig. 1, the refrigerator of optimizing the cold wind circulating path is equipped with return air baffle plate 2 on the cover plate 11 of evaporimeter 1, and return air baffle plate 2 upper ends are fixed on the cover plate 11 of evaporimeter 1, return air baffle plate 2 lower ends unsettled and and evaporimeter 1 between form return air inlet 3.
Referring to Fig. 2, Fig. 3, Fig. 2 is the cold wind circulating path schematic diagram of the utility model frost-free refrigerator, the schematic diagram of Fig. 3 conventional refrigerator cold wind circulating path, and the arrow among the figure is represented the flow direction of cold wind.As can be seen from Figure 3, do not install back in conventional refrigerator under the situation of windshield plate, wind directly enters return air inlet 3 along the upper edge hole of following drawer 4, can not give drawer 4 coolings down fully, caused time drawer 4 temperature to be higher than the temperature of the other parts of this chamber, after Fig. 2 the utility model refrigerator has been installed return air baffle plate 2, return air baffle plate 2 has stopped up the space between return air inlet 3 and following drawer 4 upper edge holes, the flow path of chamber interior cold wind between having changed, force cold wind flow through down drawer 4 around after, just return air inlet 3 can be entered, thereby the temperature difference of the other parts of following drawer 4 and this chamber can be reduced effectively.
As shown in Figure 4, with in two notches 12 on the cover plate 11 of the 21 insertion evaporimeters 1 of two boss on the return air baffle plate 2, by two tapping screws return air baffle plate 2 is fixed on the cover plate 11 of evaporimeter 1 more earlier.
This new refrigerator can be optimized the circulating path of cold wind well by return air baffle plate 2, increase drawer 4 air quantity all around of flowing through down, the temperature difference of the other parts of drawer 4 and this chamber under dwindling, make more uniform temperature, solved under the conventional refrigerator drawer 4 temperature effectively than the high problem of this indoor other regional temperature.
