Description

[Detailed Description of the Invention] The present invention relates to a refrigerator in which the motor part of the blower for forced circulation of cold air inside the refrigerator is provided outside the refrigerator.

Generally speaking, in a refrigerator, the motor part of the blower for forced circulation of cool air is brought out from the inside of the refrigerator body, and a hot air rising duct is formed on the back of the body to cause convection by rising heat from the compressor or condenser. The heat upward flow from the compressor rises uniformly from the bottom of the back of the refrigerator body to the top end across the hot air rise duct, and is discharged from the top.
In particular, there was a drawback that heat affected the freezing chamber and the motor section, which has a thin heat insulating wall, resulting in a decrease in cooling performance.

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 main body, which is composed 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 constitutes a hot air rising duct 12 between it and the main body 1, and has air exhaust ports 13a and 13b in a part of the side wall 12' and in the upper part.

Reference numeral 14 denotes a partition plate, which is inclined to one side on the back side that partitions the freezer compartment 6 and the refrigerator compartment 7 to partition the hot air ascending duct 12 into upper and lower sections, and has a gutter-like cross section.

Reference numeral 15 denotes a drain pipe for guiding the defrosting water from the cooler 16 to the outside of the refrigerator, and is opened upstream of the gutter-shaped partition plate 14.

The downstream side of the gutter-like partition plate 14 is formed in a cylindrical shape with a downward opening, and is connected to a drain hose 17 for discharging defrosting water, and the lower end opening of the drain hose 17 is provided at the bottom of the main body. It is guided to an evaporating dish 18.

In such a device, the heat of the compressor 10 and the condenser 9 moves upward from the bottom of the hot air rising duct 12 due to the draft effect, and is guided to one side (the inclined upper end side) by the partition plate 14 to the air outlet 13a. more excreted.

Further, the heat of the motor section 8' is discharged to the outside from the air discharge port 13b at the upper part of the hot air rising duct 12.

Furthermore, the partition plate 14 inclined to one side acts as a gutter for defrosting water.

Furthermore, the partition plate is formed in the shape of a gutter, and the defrost water from the cooler is relayed outside the refrigerator and guided to the evaporation plate provided at the bottom of the main unit through the drain hose connected downstream. The part where the drain pipe from the evaporating pan opens to the outside of the refrigerator can be left open; Because the high-temperature and humid air is sealed off by partition plates, and the drain pipe and drain hose are relayed separately up and down, the air sucked from the drain hose is usually routed from the drain pipe to the cooler. In addition to being installed outside the refrigerator, the entire bottom of the gutter is kept warm by the upward flow of heat from the compressor, so it can be used as a similar relay installed inside the refrigerator. Unlike gutters, there is no risk of freezing.

In this way, the present invention not only promotes heat dissipation from the condenser by utilizing the inducing effect of the upward flow of hot air from the compressor, but also improves cooling efficiency by preventing the compressor's heat from affecting the freezer compartment and blower motor. In addition to increasing the reliability of the blower, the partition plate is formed into a gutter shape and is used as a gutter to guide defrost water from the cooler to the outside of the refrigerator, so the drainage structure can of course be simplified. The partition plates are warmed by the rising flow of hot air, and stable drainage is possible without the risk of freezing of the defrosted water.
