Description

[Detailed Description of the Invention] The present invention relates to a refrigerator in which a motor section of a blower for forcibly circulating cold air inside the refrigerator is disposed outside the refrigerator.

In this type of conventional system, the motor part of the blower for circulating cold air is brought out from inside the refrigerator, and a hot air ascending duct is provided on the back of the refrigerator body, and a convection effect is created by the upward flow of hot air from a compressor installed below the duct. In so-called draft effect type refrigerators that dissipate heat from a compressor installed at the bottom of the main body, on the other hand, the hot air from the compressor rises uniformly across the back of the main unit and is discharged from the top. In particular, a freezer room, which is a low-temperature storage room,
There was a drawback that the blower motor housing had a thin insulation wall and had a strong thermal effect.

The present invention provides a refrigerator that improves the above-mentioned drawbacks.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a refrigerator body, which is made up of an outer box 2, an inner box 3, and a heat insulating material 4 filled between the two boxes, and is divided by a dividing wall 5 into a freezing compartment 6 in the upper part and a refrigerating compartment 7 in the lower part. .

Circulation of cold air within the freezer compartment 6 and the refrigerator compartment 7 is carried out by a blower 8 having a motor section 8' mounted outside the back of the freezer compartment 6.

9 is a condenser provided at the bottom of the main body, and 10 is a compressor.

Reference numeral 11 denotes a duct plate provided on the rear surface of the main body, which forms a hot air ascending duct 12 between it and the main body 1, and has air exhaust ports 13a and 13b at a portion of both side walls 11' and at the top.

The air exhaust ports 13a of the both side walls 11' are located below the partition between the freezer compartment 6 and the refrigerator compartment 7.

Reference numeral 14 denotes a partition plate which divides the hot air rising duct 12 into upper and lower sections by using a downwardly bent V-shape on an extension of the rear surface that partitions the freezer compartment 6 and the refrigerator compartment 7.

Note that the bottom surface of the refrigerator main body 1 is open.

In such a device, hot air from the compressor 10 and condenser 9 moves upward from the bottom of the hot air rising duct 12 due to the draft effect, is divided into left and right by the partition plate 14, and is discharged from the air outlet 13a. Since this heat does not warm the back side of the freezer compartment 6, the external heat load on the freezer compartment 6 is reduced.Moreover, the heat of the motor section 8' of the blower 8 is released to the outside from the air outlet 13b, so the motor section The thermal influence on 8' can also be reduced.

In this way, the present invention has a hot air rising duct that sucks the heat radiated from the compressor and condenser at the bottom of the refrigerator body by a draft action. A partition plate is installed at the top of the duct to partition the inside of the duct into upper and lower parts, and a blower motor for circulating cold air inside the refrigerator is installed at the upper part of the duct. Since the air outlet is formed at the top, not only can the heat dissipation from the compressor etc. be promoted by attracting outside air, but also the hot air does not flow upward into the freezer compartment, and the heat is transferred to the freezer compartment and motor. The effects can be eliminated.

In addition, the lower surface of the partition plate is V-shaped, and the air outlet below the partition plate is provided on both sides of the hot air rising duct, so the hot air flowing up inside the duct is divided into both sides by the partition plate. It is further guided upward to both sides and flows smoothly, further enhancing the drafting effect.
