[0008]

In recent years, refrigerators tend to have a large capacity, for example, by increasing the height of the vegetable compartment so that plastic bottles, beer bottles, etc. can be stored in the vegetable case. The height of the refrigerator is limited due to the storage space of the refrigerator at home and the convenience of use. Therefore, the improvement of the utilization efficiency of the internal volume of the refrigerator is an essential technique for coping with the increase in capacity, and the reduction of the storage space in the evaporation tray of the evaporation device has also been an issue.

However, in the conventional structure, in addition to the height of the legs 18 of the refrigerator, the height of the storage space for the evaporation plate 10 is required, so that the volume utilization efficiency of the lower portion of the refrigerator body 1 is poor. Further, when the evaporation plate 10 is located below the lower side of the side plate, the evaporation plate 1 is transported during transportation as shown in FIG.
There was a problem that 0 would get on the step and cause damage.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and increases the internal volume that can be effectively used and prevents the evaporator from being damaged or deformed during transportation. It is intended to provide.

[0011]

Therefore, in the refrigerator according to the present invention, the side plate forming the side surface of the refrigerator, the side plate reinforcing member attached to the lower edge portion of the side plate, and the side plates on both sides are connected to the bottom of the refrigerator. A refrigerator comprising a closed bottom plate and an evaporation device arranged below the bottom plate, wherein a lower surface of the evaporation device is positioned lower than a side plate reinforcing member, and a side surface of the evaporation device is lower than a lower surface of the evaporation device. Also, the above-mentioned object is to be achieved by a structure characterized in that a bottom protection member protruding downward is provided.

[0012]

With the above construction, the evaporation device whose lower surface is located below the side plate reinforcing member can be located below the conventional device, and thus the bottom plate located above the evaporation device is also located below the conventional device. Therefore, when compared with a refrigerator having the same outer shape as the conventional refrigerator, the effectively usable internal volume can be increased more than that of the conventional refrigerator.

Moreover, the bottom protection member is provided on the side of the evaporator,
Since it is provided so as to project below the lower surface of the evaporator, it is possible to prevent the evaporator from being deformed or damaged during transportation.

[0014]

Embodiments of the refrigerator according to the present invention will be described below.

FIG. 1 is a vertical cross-sectional view showing the structure of the first embodiment, and FIG. 2 is a cross-sectional view of the main part of an evaporator portion (shown by ZZ line in FIG. 1) installed at the bottom of the same embodiment. It is a figure. The same or corresponding parts as those of the conventional refrigerator are designated by the same reference numerals, and the duplicated description will be omitted.

With reference to both figures, the structure of the peripheral portion of the evaporator and the position of the evaporator provided in the bottom portion of the refrigerator, which is a feature of the embodiment, will be described below.

Both lower sides of the side plate 2 are bent in an L shape to form a lower flange 2a. Inside the lower flange 2a, a side girder 3 which is a side plate reinforcing member having a substantially U-shaped cross section is attached. Reference numeral 19 is a bottom protection member formed of synthetic resin and having a length corresponding to the length of the evaporation plate 10a and having a substantially U-shaped cross section. The bottom protection member 19 is engaged with the bottom plate 4 by being locked by the inner flange 3a, and the bottom end of the bottom protection member 19 is between the bottom of the evaporation plate 10 and the floor (G, L) where the refrigerator is installed.

The defrosting water can be vaporized as in the conventional example. Even if the lower surface of the evaporation device 10 is arranged lower than the bottom flange 2a at the lower edge of the side plate 2, the evaporation device 10 is equipped with the bottom protection members 19 protruding below the evaporation plate 10 on both sides of the evaporation device 10. For example, unlike the conventional example, the evaporator 10 is not damaged even if it is handled by inclining the stepped portion during transportation, unlike the conventional example, and the bottom plate 4 is provided closer to the bottom flange 2a than in the conventional case. The internal volume of the refrigerator can be increased.

Further, since the bottom plate 4 is pushed down by the foaming pressure of the heat insulating material, the bottom protection member 19 can be firmly held and fixed between the bottom protection member 19 and the side girder 3, without using fasteners such as screws. The bottom protection member 19 can be attached easily and reliably.

[0030]

As described above, according to the present invention, the evaporation device whose lower surface is located lower than the side plate reinforcing member can be positioned lower than the conventional one, and therefore is located above the evaporation device. Also, since the bottom plate can be located below the conventional refrigerator, the internal volume that can be effectively used can be increased compared to the conventional refrigerator when compared with the refrigerator having the same outer shape as the conventional refrigerator.

Further, since the bottom protection member is provided so as to project to the side of the evaporator and below the lower surface of the evaporator, the evaporator is deformed / damaged even when riding on, for example, a step during transportation. There is nothing to do.
