no. 1 approach

[0032] Fig. 1 is a schematic front view showing a refrigerator according to a first embodiment of the present invention. In FIG. 1 , the heat insulation box 101 is divided into two heat insulation sections, the upper part and the lower part are revolving door structures, wherein the upper part is a refrigerating room 102 and the lower part is a freezing room 103 . Insulation doors are respectively provided in each heat insulation section, and from above are the refrigerator compartment revolving door 105 and the freezer compartment revolving door 106 . A door built-in shelf 134 is provided on the revolving door 105 of the refrigerator as a storage space, and a plurality of storage shelves 108 are provided in the refrigerator.

[0033] In the refrigerating cycle, a compressor 116 and a condenser 117 arranged on the upper part 150 of the top surface, a capillary (not shown) as a decompressor (not shown), and an evaporator ( not shown in the figure).

[0040] Fig. 2 is a schematic cross-sectional view showing a refrigerator according to a second embodiment of the present invention. In FIG. 2 , the heat insulation box body 201 is divided into two heat insulation sections, and the upper part has a revolving door, while the lower part has a drawer door structure, wherein the upper part is a refrigerator compartment 202 and the lower part is a freezer compartment 203 . Insulation doors are respectively provided in each heat insulation section, and from above are the revolving door 205 of the refrigerator compartment and the drawer door 206 of the freezer compartment. A refrigerator compartment shelf 260 and a freezer compartment storage box 261 are respectively provided on the refrigerator compartment revolving door 205 and the freezer compartment drawer door 206 as storage spaces.

[0041] The refrigerating cycle is a condenser 217 arranged on the first top 250, a compressor 216 arranged behind the refrigerator on the first top...

no. 3 approach

[0046] Fig. 3 is a schematic cross-sectional view showing a refrigerator according to a third embodiment of the present invention. 4 is a cross-sectional view showing a vacuum heat insulating material, FIG. 5 is a plan development view showing the refrigerator except for the front door, and FIG. 6 is a schematic cross-sectional view showing the refrigerator when it is tilted.

[0047] In FIG. 3 , the heat insulation box 301 has a heat insulation wall formed by vacuum forming an inner box 322 made of a resin such as ABS and an outer box 323 made of a metal material such as a pre-coated steel plate. The foam insulation body 324 is injected into the space to form. For the heat insulating foam body 324, for example, hard urethane foam, phenol foam, styrene foam, etc. can be used. As a foaming material, use of cyclopentane, a hydrocarbon, contributes more to avoiding the problem of global warming.

[0048] Moreover, in the space comprised by the inner case 322 and the outer case ...

Abstract

A refrigerator has a heat-insulated box body (101), a compressor (116) is placed on the top surface section (150) of the box body, and at least two or more heat-insulated sections are arranged in the vertical direction in the box body. The heat-insulated box body (101) is constructed from an inner box, an outer box, a foamed heat insulation body (115), and a vacuum heat insulation body (125) having higher density than the foamed heat insulation body (115). The total weight or volume of the vacuum heat insulation body (125) placed below the lower end surface (145) of the uppermost heat-insulated section, the uppermost section of the heat-insulated sections, is greater than the total weight or volume of the vacuum heat insulation body (125) placed above the lower end surface (145) of the uppermost heat-insulated section.

Description

technical field [0001] The invention relates to a refrigerator with a compressor mounted on the top Background technique [0002] In recent years, from the viewpoint of environmental protection, it is necessary to further realize energy saving of refrigerators and improve the usability and storage properties thereof. With regard to the existing refrigerator, for the purpose of expanding the storage volume of the storage room arranged at the bottom, a sunken recess is provided on the uppermost back of the storage room of the heat-insulating box, and the A form in which components of the refrigeration cycle are accommodated in the recess. For example, it is disclosed in Japanese Patent Application Laid-Open No. 2001-99552. [0003] What FIG. 15 shows is the structure of the conventional refrigerator disclosed by the said patent document. As shown in FIG. 15 , in the heat insulation box 1 , a refrigerator compartment 2 , a freezer compartment 3 , and a vegetable compartment ...
