In FIG. 1, in a refrigerator with a stand 1 according to the present embodiment, a machine room 500 is formed so as to extend over the refrigerator main body 100 and the rear of the stand 500.

That is, the refrigerator main body 100 is provided with a rising wall 107 formed on the bottom surface 106 of the storage room 10 at a position smaller than the inside of the refrigerator by a depth D1 and a height, By forming a step portion 109 composed of a horizontal surface 108 continuous from the upper end of the rising wall 107 provided with H3 to the rear wall at the rear, a rear lower portion of the refrigerator main body 100 is formed. A concave space 400 a constituting the upper part of the machine room 400 is formed in the machine room 400.

In addition, below the concave space 400a, a compressor support plate 450 constituting the bottom of the machine room 400 is formed by projecting downward, so that a convex shape projecting downward is provided. A space 400b is formed. The convex space 400 b and the concave space 400 a constitute the machine room 400.

On the other hand, the base 500 has a storage section 501 formed in a concave shape at the rear of the upper surface in order to store the convex space 400b. These detailed structures will be described with reference to FIG.

It is a thin-walled molded product opened to the lower side (in the drawing), and has a plurality of ribs 503 as reinforcing members for supporting the refrigerator main body 100. On the upper surface of the base 500, both sides and a front part are formed in a flat shape, and a rear center is formed in a concave shape to form the storage part 501.

Further, on both sides of the upper surface of the upper surface of the base 500, fitting recesses 504 are formed for fitting with the positioning projections 115 (see FIG. 1) of the refrigerator body 1 shown in FIG. . In this embodiment, the refrigerator main body 100 is placed above the base 500 by fitting the positioning projections 115 and the fitting recesses 504 and fitting the machine room 400 to the storage section 501. It is installed so that it does not deviate from it.

Here, in the present embodiment, the excess weight of the refrigerator main body 100 is supported by flat surfaces 505 formed on both sides of the upper surface of the base portion 500 and a front portion thereof, and the compressor support plate 4 is provided. No extra weight is added to 50. Therefore, the compressor support plate 450 is provided with a compressor 410 It is only necessary to have sufficient strength to support, so it is not necessary to be concerned with metal materials and a resin molded product may be used. For this reason, there is no need to simplify the structure and take time for reinforcement.

As a more preferred embodiment, the overall strength of the compressor support plate 450 may be increased by increasing the thickness of the compressor support plate 450, or by giving a reinforcing rib or unevenness to the surface, or by further improving the compressor support plate. By providing the legs on the plate 450, even when the refrigerator main body 1 and the base 500 are separated during assembly or maintenance, the machine room 500 that protrudes downward can be used as a floor surface. In this case, damage caused during the heat treatment, for example, damage to the welded portion of the refrigerant pipe of the compressor 401 can be reduced.

Returning to FIG. 1, as described above, the refrigerator with a stand 1 according to the present embodiment is configured such that the machine room 400 is located at the height of the refrigerator main body 100 (the height of the concave space 400a). Height) Y 1 and the height of the base 500 side (height of the convex space 400 b) Y 2 occupies substantially the same size, so that the refrigerator main body 100 and the base are the same. It is provided across the back of the section 400. With this structure, the space for providing the machine room 500 in the refrigerator main body 100 is reduced, so that the stepped portion 109 protruding downward in the storage room 10 is reduced. Therefore, the storage space of the storage room 10 can be widened.

In particular, a great effect of this embodiment is that the dead space of the base 500 for simply installing a refrigerator is a storage space 501 for storing the compressor 401, and In addition, the storage space of the storage room 10 can be easily expanded without largely changing the overall height H and without making design changes that significantly change the structure.

The effect is that the machine room 400 occupies the refrigerator main body 100. This can be achieved by increasing the ratio, that is, the size of the convex space 400b. However, in order to obtain a greater effect, the height Y of the convex space 400 b is such that a storage space for the vegetable compartment 40 can be obtained above the horizontal plate 108 of the step portion 109. Need to set 2.

For example, in a conventional small refrigerator, a vegetable compartment storage container 41 of the same size (height) P 1 as the height H 3 of the horizontal surface 108 of the step portion 109 is usually provided. The upper surface of the refrigerator compartment 50 and the horizontal plane 108 are made coincident with each other to make the storage space of the refrigerator compartment 50 a substantially rectangular parallelepiped, thereby improving the ease of use of the refrigerator compartment 50. The height P 2 of the vegetable room storage container 41 is generally about 230 mm in this type of small refrigerator. The height P 3 is caused by the size of the machine room. If the force is increased, the capacity can be increased, but vegetables are difficult to remove. Conversely, if the height P3 is reduced, no capacity can be obtained. Therefore, if the height H3 of the step portion 109 is reduced halfway, the capacity of the vegetable compartment 40 will be reduced.

Therefore, in the present embodiment, the storage container 41 is extended to a position above the horizontal plane 108 of the step portion 109, and a height P2 at which the expanded space can be used as a storage space is set. ing. Specifically, in the present embodiment, the above P2 is set to 85 mm, and a space for storing the side cans, package use, beer or small vegetables is secured in the expanded storage space. .

With a sufficient storage space behind the storage container 41, the effect cannot be obtained simply by slightly extending the machine room 400 slightly downward. That is, for example, even if the compressor 401 is lowered by about 30 mm in accordance with the leg of about 40 mm provided at the lower part of the refrigerator, the same effect as the present invention can be obtained. It is not possible. In other words, for example, at least the height P2 that can store enough juice (55 mm) or beer (65 mm) that can easily be stored together with vegetables in the vegetable compartment 40, specifically, At least 70 mm high enough to hold the side canned beer described above, and a good product is at least half the height of a conventional compressor 401 with a height of about 170 mm. In this case, it is necessary to extend 100 mm below the refrigerator, and to make the overhanging compressor 401 unaffected by the appearance, and to stably install the entire refrigerator. In the present embodiment, this problem is solved by providing a base 500 below the refrigerator main body 100 so that the base 500 can accommodate at least half of the compressor 401. A machine room 400 is disposed so as to straddle 00 and the rear of the base 500.
