Description

[Detailed Description of the Invention] The present invention relates to a refrigerator that is improved so that water vapor from an evaporating dish can escape to the outside by natural convection.

Generally, an evaporation tray is installed below the bottom of the refrigerator body to store and evaporate defrosting water, but since the bottom plate of conventional refrigerators is installed horizontally, steam from the evaporation tray It is difficult for moisture to escape to the outside, and as a result, there is a problem in that moisture gets trapped in the lower part of the refrigerator body, causing rust, especially at the edge of the bottom plate, where the coating tends to be incomplete.

Therefore, the purpose of the present invention is to provide a refrigerator that can effectively prevent the bottom plate from rusting by sloping the bottom plate of the refrigerator body to promote natural airflow and allow moisture to escape to the outside. There is something to do.

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a refrigerator main body, which has an inner box 3 made of plastic inside an outer box 2 made of iron plate, and connects the two with a front frame 4 made of iron plate. It is formed by filling the inside with a heat insulating material 5.

The bottom plate 2a of the outer box 2 is provided so as to be inclined diagonally upward from the front toward the rear, and a recess 6 is formed at the rear, and a compressor 7 is disposed within the recess 6. .

8 is a condenser attached to the back of the refrigerator body 1.

Reference numeral 9 denotes a plate that is attached to the lower bottom of the refrigerator body 1, and a hot pipe 10 is attached to the lower surface of the plate.

Reference numeral 11 denotes an evaporating dish placed in front of the compressor I, and the receiver is placed on the plate 9, and the handle 11a bent at the front part is close to the flange part 4a at the lower end of the front frame 4. There is.

Notches 12 are formed intermittently in the 7 flange portions 4a of the front frame 4 at the lower end of the front surface of the outer box 2, and in the vicinity of the front edge of the bottom plate 2a of the outer box 2, there are cutouts 12 in the evaporating dish 11. The facing protruding portion 13 is formed to protrude downward.

The defrosting water from the cooler is dripped into the evaporating tray 11 through a drain pipe (not shown), and the water stored in the evaporating tray 11 is high-temperature and flows through the hot pipe 10 when the compressor I is in operation. It is heated by the refrigerant and evaporates.

On the other hand, the air around the compressor I is warmed by the operating heat of the compressor I, rises, and escapes from the recess 6 to the rear.

Accordingly, the steam from the evaporating dish 11 flows along the bottom plate 2a of the outer box 2 in the direction of the recess 6 as shown by arrow A, and escapes to the outside through the recess 6.

Due to the generation of such airflow, outside air is sucked in from the notch 12 of the flange portion 4a of the front frame 4 as shown by arrow B, and
In addition to blowing away the moisture that has accumulated inside the flange portion 4a, the moisture that has accumulated inside the flange portion a is also vigorously sucked from the small gap between the flange portion 4a and the handle 11a of the evaporating dish 11 as shown by arrow C. 1.
'(Remove.

It should be noted that if dew formation occurs on the bottom plate 2aV(-), the water droplets are removed into the evaporating dish 11 by the draining action of the protruding portions 13.
Therefore, it is possible to effectively prevent inconveniences such as water droplets being transmitted on the edge of the bottom plate 2a or the flange portion 4a of the front frame 4 and becoming a source of rust.

As explained above, in this invention, the bottom plate of the outer box is oriented toward the back of the Z, 1 umbrella installation side' (1 facing diagonally upward).
5, it promotes the generation of white heat in the airflow and reduces evaporation U.
The water vapor from the bottom plate is allowed to flow backward along the bottom plate, so that the moisture that tends to be trapped below the bottom plate can be released to an external force, and the occurrence of rust on the bottom plate can be prevented as much as possible.

11. Since the notches 4 and 5 are formed in the flange at the lower front end of the outer box, the air flowing into the lower blade of the bottom plate enters into the inside of the flange through the notch, and the air flows inside the flange. This has the excellent effect of blowing away moisture and preventing rust from forming, especially at the edges of the bottom plate where the coating tends to be incomplete.
