Description

refrigerator

An embodiment of the present invention relates to a refrigerator.

For example, a household refrigerator has a tendency to increase its internal volume. In the refrigerator, the increase in the internal volume is not achieved by increasing the thickness of the heat insulating box of the refrigerator body, but by thinning the thickness of the peripheral wall of the heat insulating box. In this case, it is necessary to ensure sufficient heat insulating performance even if the peripheral wall is made thin. For this reason, in addition to the fact that the peripheral wall of the heat insulating box is filled with a heat insulating material (Heat Insulating Materials), a technique using a vacuum insulating panel is employed. In addition, a technique of filling the peripheral wall of the heat insulating box with only a vacuum heat insulating panel is also considered. Further, the vacuum heat insulating panel is a heat insulating panel having a heat insulating property higher than that of the foaming heat insulating panel, in other words, it is a heat insulating panel having a low thermal conductivity.

The vacuum heat insulating panel is a core material in which, for example, a glass wool of fine glass fibers is formed into a mat shape, and the core material is placed in an aluminum foil and a synthetic resin. In a gas barrier container in which a laminated film is laminated and vacuum-treated, the inside is evacuated to block the open panel. Thereby, the vacuum heat insulating panel is a panel which maintains the inside of a container in a vacuum-decompression state. Although the vacuum insulation panel is thin, it retains a low thermal conductivity, in other words, it maintains high heat insulation. Therefore, by using The vacuum insulation panel ensures high insulation of the peripheral wall of the heat insulation box.

In this case, the number of wall portions is five. The bottom wall portion 1b, the left side wall portion 1c, the right side wall portion 1d, and the rear wall portion 1e have a rectangular flat plate shape except for the top wall portion 1a. The top wall portion 1a has a lower step shape in the rear portion. When the top wall portion 1a has a stepped shape, when the plurality of wall portions 1a to 1e are combined to form the heat insulating box 1, the machine room 3 is formed at the rear portion of the upper portion of the heat insulating box 1. A compressor or the like of a refrigeration cycle (not shown) is disposed in the machine room 3.

Here, the configuration of each of the wall portions 1a to 1e will be described. First, the heat insulating function of each of the wall portions 1a to 1e is obtained by a heat insulator such as the vacuum heat insulating panel 4.

Further, the vacuum heat insulating panel 4 and the inner casing 8 are integrated by being fixed to each other by adhesion or the like. Thereby, the vacuum heat insulating panel 4, the outer casing 7, and the inner casing 8 are integrated. Further, in FIGS. 6(a) and 6(b), a flat wall portion is shown. However, the top wall portion 1a has a stepped shape.

In each of the wall portions 1a to 1e, the longitudinal dimension and the lateral dimension of the inner casing 8 are smaller than that of the outer casing 7. In addition, the longitudinal heat insulating panel 4 has a smaller longitudinal dimension and lateral dimension than the inner casing 8. Therefore, the four sides (i.e., the four ends) of the vacuum heat insulating panel 4 do not reach the four sides (i.e., four ends) of the outer casing 7, and do not reach the four sides (i.e., four ends) of the inner casing 8. That is, the four sides of the vacuum heat insulating panel 4 are present at positions deeper than the four sides of the outer casing 7 and the inner sides of the inner casing 8. Further, a connecting piece 9 bent at a right angle is formed on a predetermined side of the four sides of the outer casing 7 of each of the wall portions 1a to 1e. The connecting piece 9 formed on the desired side of each of the wall portions 1a to 1e is for connecting the outer casings 7 adjacent to each other with a screw or the like by screws or the like.

Further, a vertical frame 13 is attached between the horizontal frame 11 of the middle portion of the heat insulating box 1 and the horizontal frame 12 of the lower stage. Moreover, although not shown, it is behind the horizontal frames 10 to 12. The side walls and the rear side of the vertical frame 13 are provided with heat insulating walls or partition plates. By the heat insulating wall and the partitioning plate, the storage space 2 is sequentially partitioned into a refrigerating compartment 2a, a vegetable compartment 2b, an ice making compartment 2c, a specification switching chamber 2d, and a freezing compartment 2e from top to bottom. Further, the ice making compartment 2c and the specification switching chamber 2d are arranged side by side in the lateral direction. Further, a door (not shown) for opening and closing the front surfaces of the respective storage chambers 2a to 2e is attached to the front surface of the heat insulating box 1.

The refrigerator is provided with two evaporators for refrigeration and freezing as a cooler. The refrigerating evaporator is disposed in a cooling chamber formed in the inner portion of the refrigerating chamber 2a. The freezing evaporator is disposed in a cooling chamber formed in the inner portion of the freezing compartment 2e. Further, the cold air cooled by the two evaporators is blown to the refrigerating compartment 2a, the vegetable compartment 2b, the ice making compartment 2c, the specification switching chamber 2d, and the freezing compartment 2e by a fan. Thereby, the refrigerating compartment is cooled to the refrigerating temperature, and the freezing compartment is cooled to the freezing temperature.

Further, the right end of the inner casing 8e of the rear wall portion 1e is attached to the surface of the rear end portion of the inner casing 8d of the right side wall portion 1d.

As described above, in each of the wall portions 1a to 1e, the end of the vacuum heat insulating panel 4 is slightly short and does not reach the end of the outer casing 7. Therefore, in the right side wall portion 1d and the rear wall portion 1e which are connected to each other, the internal vacuum heat insulating panel 4d and the vacuum heat insulating panel 4e are spaced apart from each other with a gap G therebetween. Further, in the gap G, a sponge-like heat insulating material 14 is filled when the right side wall portion 1d and the rear wall portion 1e are combined.
