Description

[Detailed Description of the Invention] The present invention relates to a refrigerator which is provided with a hot air ascending duct for heat radiation on the back of the main body.

Conventionally, this kind of device has a hot air rising duct for heat radiation on the back of the main body, and a part of this hot air rising duct is equipped with a condenser.
There was a refrigerator that used an upward flow of hot air from a compressor to promote heat dissipation from a condenser.

However, in this example, on the other hand, the upward flow of hot air from the compressor exerts a strong thermal influence on the condenser, which has the disadvantage that the heat dissipation efficiency of the condenser decreases.

It is also possible to divide the hot air rising range of the compressor into the left and right sides of the hot air rising duct, but due to the positional relationship, it is difficult to bring a sufficient attracting effect to the condenser duct, and the heat dissipation effect is significantly reduced. It was something to do.

The present invention provides a refrigerator that improves the drawbacks of the above examples.

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

In the figure, reference numeral 1 denotes a refrigerator 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 in the upper part and a refrigerating compartment 7 in the lower part. .

Further, a duct plate 9 having a plurality of ventilation holes 8 above the electric compressor 13 provided at the bottom of the main body 1 is attached to the back of the main body 1 with a predetermined gap between the main body 1 and the electric compressor 13 provided at the bottom of the main body 1.
A hot air rising duct 10 is formed between the two.

Further, a partition plate 12 is provided in the hot air rising duct 10 facing the ventilation hole 8 of the duct plate 9 so as to form an auxiliary duct 16 having an open top surface.

This partition plate 12 divides the hot air ascending duct 10 into front and rear parts, with one side serving as an auxiliary duct 16.

Further, a condenser 11 is provided within the auxiliary duct 16.

This condenser 11 is attached to the back of the main body 1 together with a partition plate 12, and when the duct plate 9 is then attached to the back of the main body 1, the partition plate 12 and the duct plate 9 are screwed together.

Reference numeral 14 denotes an air discharge port provided at the upper part of the hot air rising duct 10.

15a and 15b are spacers that form a gap with the wall surface 17 of the installation part of the refrigerator.

The bottom of the main body 1 is open so that outside air can flow into the hot air rising duct 10.

In such a device, the upward flow of hot air from the electric compressor 13 passes through the outer circumference of the partition plate 12 and into the hot air rising duct 10.
At the same time, the rising hot air from the electric compressor 13 induces air to be drawn into the auxiliary duct 16 whose upper end opening communicates with the hot air rising duct 10.

On the other hand, the air sucked in through the ventilation hole 8 provided in the duct plate 9 is transferred to a condenser 11 provided opposite thereto.
The heated air exchanges heat with the hot air and becomes an upward flow, which is discharged from the upper end opening of the partition plate 12. At the point when the hot air is discharged from the upper end opening of the partition plate 12, it merges with the hot air upward flow from the compressor 13, rises in the duct 10, and is similarly discharged from the discharge port 14. be done.

As is clear from the above embodiment, the present invention has a structure in which an auxiliary duct with an open top is formed in the hot air rising duct with a partition plate, and this auxiliary duct is equipped with a condenser. The flow rises through the outer periphery of the partition plate and has no direct heat effect on the condenser. In addition, the hot air rising duct is divided into front and rear sections within the hot air rising range of the compressor.
This eliminates the problem of lack of attractive force as in the case of left and right divisions as in the past.

In addition, since a ventilation hole dedicated to the condenser is provided in the duct plate that constitutes the hot air rising duct facing the condenser, the condenser is constantly heated by the upward flow of hot air from the compressor. External air that has not been heated is sucked in, exchanged heat with the condenser, and then combined with the upward flow of hot air from the compressor and simultaneously discharged from the upper discharge port.
