To do.

According to a second aspect of the present invention, in the refrigerator, the condenser and the compressor are arranged in a front and rear positional relationship in the compressor base, the intake ports are provided on the front side and one of the left and right sides, and the cooling fan device is provided. Is provided on the other side of the left and right sides of the rear part, and the exhaust port is provided at a portion facing the cooling fan device.

[0007]

[Action]

 According to the means of claim 1, since the compressor base is extended to the front side of the machine room, the intake and exhaust ports are formed in the compressor base, and the compressor, the condenser, and the cooling fan device are arranged. A cooling air passage can be constructed without using a duct outside the compressor base.

According to the second aspect of the present invention, the air (wind) sucked from the front intake port of the compressor base and the air (wind) sucked from the side intake port respectively pass through the condenser and the compressor. Since they are cooled, both can be cooled efficiently.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The refrigerator main body 21 is installed so as to be separated from the floor by legs (not shown), and a recess 21a is formed on the lower rear side of the refrigerator main body 21. A machine room 24 is formed by closing the bottom surface of the recess 21a with a compressor base 22 as a bottom plate formed of, for example, a metal plate material in the shape of a rectangular container, and closing the back surface with a back cover 23. There is.

A front portion of the compressor base 22 extends at a lower portion of the cabinet body 21 so as to project to the front side from the machine room 24. A compressor 25 is disposed in a portion of the compressor stand 22 corresponding to the bottom surface of the machine room 24, and a portion extending forward of the machine room 24 is located in front of the compressor 25. A wire capacitor 26 is provided.

Further, the compressor base 22 is provided with a bell mouth 27 at one of left and right sides of a rear portion of the machine room 24, for example, at a corner portion on the left side (upper side in FIG. 1). The bell mouth 27 is arranged so as to be inclined so as to face diagonally rightward toward the front (in FIG. 1, diagonally downward toward the left). Further, a blower motor 28 is arranged in front of the bell mouth 27, and a propeller fan 29 surrounded by the bell mouth 27 is attached to a rotation shaft of the blower motor 28 to form a cooling fan device 30. .

On the other hand, the front surface of the compressor base 22 is formed with a first intake port 31 made up of a large number of through holes, and the side on which the cooling fan device 30 is arranged is on the left and right sides. On the opposite side, that is, the side surface on the right side (the side surface on the lower side in FIG. 1), a second intake port 32 also formed of a large number of through holes is formed. Further, an exhaust port 33 is formed in a portion of the back cover 23 facing the propeller fan 29 of the cooling fan device 30, that is, a left end portion (upper end portion in FIG. 1).

In FIG. 1, reference numeral 34 is a wall of a room in which the cabinet main body 21 is installed, and in FIG. 2, 35 is an evaporation tray for storing water generated during defrosting of a cooler (not shown). Is.

In the above configuration, when the blower motor 28 of the cooling fan device 30 is activated, the propeller fan 29 rotates. By the rotation of the propeller fan 29, the outside air is sucked into the compressor base 22 through the first and second intake ports 31 and 32. The outside air sucked into the compressor base 22 from the first intake port 31 flows to the bell mouth 27 side through the portion where the wire condenser 26 is provided as shown by an arrow A in FIG. The outside air sucked from the intake port 32 into the compressor base 22 flows to the side of the bell mouth 27 through the portion where the compressor 25 is provided, as shown by the arrow B in FIG. Then, the outside air sucked inside the compressor base 22 is finally discharged from the exhaust port 33 to the outside.

As described above, the compressor 25 and the wire condenser 26 are cooled by the outside air flowing through the compressor base 22. In this case, the outside air sucked through the first and second intake ports 31 and 32 directly cools the wire condenser 26 and the compressor 25, respectively, which is different from the conventional case shown in FIGS. 3 and 4. The compressor 25 and the wire condenser 26 can be efficiently cooled.

[0016]
