The air passage 45 is formed so that the air flows into the blower 23 in a horizontal direction toward the blower 23 by invading from above and below. For this reason, since the return cold air duct 35 can be arranged near the cooler 18, the duct structure can be simplified, the ventilation system can be simplified, the ventilation resistance can be reduced and good cold air circulation can be performed, and the storage room can be cooled. The effect increases. In addition, a decrease in the volume of the storage room caused when the return cool air duct has a complicated arrangement as in the related art is eliminated, and the design for increasing the volume of the storage room is facilitated. In addition, it is easy to design a duct structure in which there is no danger that the returned cool moisture will cause frost in the duct and a freezing prevention heater is not required.

The present invention also provides a refrigerator in which a plurality of storage compartments 3, 4, 5, etc. are provided in a refrigerator main body and cool air cooled by a single cooler 18 is circulated to each of the above compartments by a blower 23.

The cooling air returned from the cooling device is arranged to be sucked from below the 18 cooler. For this reason, the return cool air ducts from the storage chambers 3 and 4 above the cooler 18 are arranged above the cooler 18 and the return cool air from the front and lower storage chambers 8 and 9 is arranged above the cooler 18. Since the duct extends below the cooler 18, the duct structure can be simplified, so that the ventilation system can be simplified, the ventilation resistance can be reduced and good cool air circulation can be performed, and the cooling effect of the storage room can be improved. In addition, a decrease in the volume of the storage room caused when the return cool air duct has a complicated arrangement as in the related art is eliminated, and the design for increasing the volume of the storage room is facilitated.

For this reason, the duct configuration in the case where the vegetable room 4 is arranged at the center to improve its usability can be simplified, the ventilation resistance can be reduced, and good cool air circulation can be performed.

Further, the present invention has a structure in which the cooler 18 is disposed behind the freezer compartment 5. For this reason, a thick heat insulating structure and a heater for preventing excessive cooling that are necessary when the cooler 18 is arranged behind the refrigerator compartment or the vegetable room are not required, and the heat insulating structure is not complicated.

Further, according to the present invention, the blower 23 is a propeller type axial flow blower, and has a configuration in which a rotation axis thereof is inclined obliquely to the lateral direction of the cooler 18 in a front view of the cooler 18. For this reason, the restriction of the storage portion of the cooler by the blower is reduced, and the arrangement of the cooler having a size necessary for achieving the cooling capacity can be achieved. Further, in the conventional device, since the cool air sucked from the cooler is bent in a right angle direction by the blower, the ventilation loss is large, but in the present invention, since the blower shaft is oblique, the ventilation loss is reduced, and the cool air circulation is reduced. Efficiency is improved.

Further, according to the present invention, in the cooler 18, the refrigerant pipe 41 forms a horizontal portion 42 and bent portions 43 on the left and right sides thereof, meanders in the vertical direction, and a number of independent plate fins 44 intersect each horizontal portion 42. This is a plate fin type provided in such a manner that a horizontal passage 45 through which cool air flows to the blower 23 is formed between the plate fins 44 of the horizontal portion 42 at the upper and lower positions.

For this reason, the restriction of the storage portion of the cooler by the blower is reduced, and the arrangement of the cooler having a size necessary for achieving the cooling capacity can be achieved. Also, the cool air passing through the cooler can be favorably guided to the blower.

In the present invention, as shown in FIG. 3, the fin pitch of the plate fins 44 provided on the horizontal portion 42 of the cooler 18 is smaller than the fin pitch of the central portion of the cooler 18 in the upper and lower portions. It is a rough configuration. A lot of frost is generated on the air inlet side of the cooler, and poor ventilation is likely to occur due to the frost, but the present invention can prevent it.
Further, the attached frost is melted by the heater 19 below, and the dew generated at that time can be evaporated by the evaporating dish 20 provided below.

In the present invention, as shown in FIG. 2, the cool air return duct 35 and the cool air supply duct 26 are arranged so as not to overlap each other in the front-rear direction. That is, since the cool air return duct 35 and the cool air supply duct 26 are arranged on one plane and do not overlap each other in the front-rear direction, the thickness occupied by these ducts in the front-rear direction is reduced, as in the related art. Compared to a refrigerator in which both ducts overlap, a refrigerator having the same depth can increase the volume of the storage room.

In the above embodiment, the cooler 18 is vertically arranged along the rear wall in the refrigerator main body 1. However, depending on the form of the refrigerator, the cooler 18 is vertically arranged along one of the right and left side walls in the refrigerator main body 1. The configuration may be as follows.
