detailed description

The invention will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, the embodiments are not intended to limit the invention, and the structural, method, or functional changes made by those skilled in the art in accordance with the embodiments are included in the scope of the present invention.

In the embodiment of the present invention, the compressor compartment air guiding device of the present invention is specifically explained by taking a refrigerator as an example, but it should be noted that the technical spirit involved in the following embodiments may be alternatively utilized in other embodiments. In the form of a refrigeration device, for example, a freezer.

The words expressing position and orientation described in the present invention are preceded by a direction close to the door of the refrigerator and a direction away from the door.

The refrigerator refrigeration system includes an evaporator, a capillary tube, a solenoid valve, a condenser, and a compressor that are sequentially connected to form a circuit, in which the refrigerant circulates. Referring to FIG. 1, the condenser 10 and the compressor 20 are located in the compressor compartment 30, and the compressor compartment 30 is located at the rear of the compartment 40. The compressor cartridge 30 includes a front wall 31 adjacent the compartment 40 and a rear cover 32 opposite thereto. A plurality of through holes are formed in the rear cover 32 at a position equal to the condenser 10 and the compressor 20 to convect the air inside and outside the compressor block 30. The through holes are located on the left and right sides of the rear cover 32, and are divided into an air inlet 321 and an air outlet 322 according to the flow direction of the wind. A fan 50 is disposed between the condenser 10 and the compressor 20, and the wind at the end of the condenser 10 is discharged to the end of the compressor 20. The arrows in Fig. 1 show that eddy currents are easily formed between the compressor 20 and the wall of the compressor when the flow guiding device of the present invention is not provided.

Referring to Fig. 2, a vane 61 is disposed between the air inlet 321 and the condenser 10, and a vane 62 is disposed between the compressor 20 and the air outlet 322. The

vanes

61, 62 may have a plurality of vanes, each of which is curved to define the direction of flow of the wind.

The air inlet end 611 of the guide vane 61 has a curvature which is matched with the angle of the air inlet 321 , and the tangential direction thereof is parallel to the air inlet direction. For example, when the through hole is formed in the thin plate type rear cover 30 to form the air inlet 321 , the air inlet end 611 is perpendicular to the rear cover plate 30; when the louver type is provided with the louver type air inlet opening 321 having an oblique angle, the air inlet end 611 The tangent also has the same angle of inclination. Similarly, the arc end 622 of the vane 62 has an arc angle that matches the angle of the air outlet 322. The

vanes

61, 62 are arranged to smoothly guide the air flow to avoid the formation of eddy currents.

Referring to FIGS. 2 and 3, a hood 70 is disposed between the condenser 10 and the fan 50 to converge all of the condensing air of the condenser 10 to the fan 50. One end 701 of the hood 70 overlaps the condenser 10, and the other end 702 receives the main body of the fan 50. The shapes and sizes of the two

ends

701, 702 are matched with the condenser 10 and the blower 50.

Referring to FIG. 4, in an embodiment of the invention, evaporator 80 is housed within compartment 40. The compressor compartment 30 communicates with the compartment 40 through

switches

91, 92 provided at the tuyere. The

vanes

61, 62 are adjustable structures including

fixed portions

613, 623 and

movable portions

614, 624. The movable portion 614 of the vane 61 is pivotable about the fixed portion 613 at an angle and terminates at the P1 or P2 position. Correspondingly, the movable portion of the vane 62 can terminate at the P3 or P4 position. P1 and P3 are a pair of combinations, P2 and P4 are a pair of combinations, and the

vanes

61, 62 must be in a pair of combined positions at the same time.

As shown by the dashed line in Fig. 4, when the movable portion 614 is in the P2 position and the movable portion 624 is in the P4 position, the

switches

91, 92 are simultaneously closed. At this time, the fan 50 dissipates heat to the compressor compartment 30 to the outside of the refrigerator.

As shown by the solid line in FIG. 4, when the movable portion 614 is at the P1 position and the movable portion 624 is at the P3 position, the

switches

91, 92 are simultaneously opened, and the compressor chamber 30 is electrically connected to the compartment 40. At this time, the movable portion 614 and the fixed portion 613 form an arc-shaped air guiding structure, and the air flow direction is guided between the switch 91 and the condenser 10. Similarly, an arcuate wind guiding structure is also formed between the compressor 20 and the switch 92. Thus, the fan 50 drives the compressor compartment 30 to dissipate heat to the compartment 40, defrosting the evaporator 80.

Referring to Fig. 5, in an embodiment of the invention, the evaporator 80 is fixed to the rear of the compartment rear partition and the cold volume generated by the evaporator is introduced into the compartment through the air passage. The air duct includes a damper 93 that communicates with the compartment and a pair of dampers 94 (one of which is shown) that are coupled to the compressor compartment. The structure of the compressor compartment air guiding device is the same as that of the embodiment of Fig. 4. When the damper 93 is opened, the damper 94 is closed, and the evaporator 80 exchanges only with the compartment 40 for cooling. When the damper 94 is opened, the damper 93 is closed, and the compressor compartment 30 dissipates heat to the air duct, thereby defrosting the evaporator 80.

It should be understood that, although the description is described in terms of embodiments, the embodiments are not intended to be construed as a single. The technical solutions in the embodiments may also be combined as appropriate to form other embodiments that can be understood by those skilled in the art.

The series of detailed descriptions set forth above are merely illustrative of the possible embodiments of the present invention, and are not intended to limit the scope of the present invention. Changes are intended to be included within the scope of the invention.
