Problems solved by technology

In addition, the projection dimension into the freezer compartment 103 of the cooling compartment in which the evaporator 20 is accommodated becomes large, and the depth in the box is occupied, the storage capacity is reduced, and the storage capacity is deteriorated.
[0017] Moreover, there are differences in storage capacity and storage performance between the storage room at the bottom and the storage room directly above it, that is, the freezer room 103 and the vegetable room 4.
In the case of a drawer-type storage room, there is a difference in the draw-out amounts of the storage containers 9A and 9B, which deteriorates the usability and increases the manufacturing cost.

Embodiment approach 1

[0032] Fig. 1 is a front view of refrigerator 1001 according to Embodiment 1 of the present invention. FIG. 2 is a front view of heat insulating box 50 of refrigerator 1001 . Fig. 3 is a cross-sectional view along line 3-3 of refrigerator 1001 shown in Fig. 1 . 4 and 5 are perspective views of main parts of refrigerator 1001 .

[0033] The heat-insulating box 50 , which is insulated from the surroundings by a heat-insulating material such as rigid polyurethane foam, is divided into a plurality of zones to form a plurality of storage rooms. The uppermost storage room among the plurality of storage rooms is the refrigerator room 51 . Immediately below refrigerator compartment 51, ice maker compartment 52 and first freezer compartment 53 partitioned by a heat-insulating partition are arranged side by side. The lowermost store room is the second freezer room 54 . Between the ice making compartment 52 and the first freezing compartment 53 and the second freezing compartment 54 ...

Embodiment approach 2

[0090] Fig. 6 is a cross-sectional view showing refrigerator 2001 according to Embodiment 2 of the present invention. In FIG. 6 , the same reference numerals are assigned to the same parts as refrigerator 1001 according to Embodiment 1 shown in FIG. 1 , and description thereof will be omitted.

[0091] As shown in FIG. 6 , a second concave portion 203 is formed outside the cooling chamber 202 at the lower rear of the heat insulating box 201 . A condenser 204 is accommodated in the concave portion 203 . The other condensers of the condenser 204 can also be located in other positions.

[0092] Evaporator 205A for evaporating defrosting water includes evaporating pan 205 as a water storage unit and piping 87 . The evaporating dish 205 is installed at the bottom of the second concave portion 202 and is heated by heat transfer from the piping 87 that is a part of the condenser 204 . That is, the piping 87 functions as a heating unit that heats the defrosting water stored in the ...

Embodiment approach 3

[0096] Fig. 7 is a cross-sectional view of refrigerator 3001 according to Embodiment 3 of the present invention. In FIG. 6 , the same reference numerals are assigned to the same parts as refrigerator 1001 according to Embodiment 1 shown in FIG. 1 , and description thereof will be omitted.

[0097] As shown in FIG. 7 , a heat insulating box 301 made of a heat insulating material such as rigid polyurethane foam forms a plurality of storage rooms divided into a plurality of areas. Among these storage rooms, the uppermost and lowermost storage rooms function as refrigerating room 302 and freezing room 303 . A storage room located between refrigerator room 302 and freezer room 303 functions as vegetable room 304 . Refrigerator compartment 302 has revolving door 305 , and freezer compartment 303 and vegetable compartment 304 have drawer-type doors 306 and 307 .

[0098] The parts constituting the refrigeration cycle unit are arranged in the same manner as in the first embodiment. ...

Abstract

A refrigerator having a thermally insulated box body, a refrigeration cycle, and an evaporation device. The refrigeration cycle has an evaporator, a compressor placed outside the thermally insulated box body, above the evaporator, and a condenser. The evaporation device is placed outside the thermally insulated box body, below the evaporator, and evaporates defrosted water produced at the evaporator. The refrigerator is easy to use and has a large storage volume.

Description

technical field [0001] The present invention relates to a refrigerator having a refrigeration cycle unit composed of a compressor, a condenser, an evaporator, and a defrosting water evaporator. Background technique [0002] In recent years, from the viewpoint of global environmental protection, along with the progress of more energy-saving refrigerators, it is necessary to improve the convenience of use and storage. [0003] In a conventional refrigerator, a machine room is formed in an area rearward outside the lowermost storage room, and a compressor of a refrigeration cycle unit is generally housed in the machine room. In this structure, not only the storage space of the lowermost storage room is occupied by the machine room to reduce the storage volume, but also the spatial shape of the storage space becomes complicated except for the protruding part of the machine room, resulting in poor storage performance. [0004] In the refrigerator disclosed in Japanese Unexamined...
