Embodiment approach 1

[0035] figure 1 It is an external perspective view schematically showing an example of refrigerator 1 according to Embodiment 1 of the present invention. figure 2 It is a schematic front view schematically showing the layout of the storage room of the refrigerator 1 . based on figure 1 with figure 2 The configuration of the refrigerator 1 will be described. In addition, in the following description, refrigerator compartment 11, ice making compartment 21, temperature switching compartment 22, vegetable compartment 31, and freezer compartment 41 may be collectively referred to as storage compartments.

[0036] Such as figure 2 As shown, the refrigerator 1 is arranged in the order of a refrigerating chamber 11 , an ice making chamber 21 , a temperature switching chamber 22 , a vegetable chamber 31 , and a freezing chamber 41 from above. The ice making chamber 21 and the temperature switching chamber 22 are arranged adjacently, the ice making chamber 21 is located on the lef...

Embodiment approach 2

[0148] Figure 8 It is an enlarged and schematic cross-sectional view of a part of refrigerator 1A according to Embodiment 2 of the present invention. based on Figure 8 1A of refrigerators in Embodiment 2 of this invention are demonstrated. Figure 8 is the same as that shown in Embodiment 1 Image 6 corresponding figure. exist Figure 8 Arrows indicate air flow.

[0149] In addition, in Embodiment 2, the difference from Embodiment 1 will be mainly described, and the same reference numerals will be attached to the same parts as Embodiment 1, and description will be omitted.

[0150] In Embodiment 2, the configuration of the fifth blowing air passage 411 is different from that of the fifth blowing air passage 411 described in Embodiment 1. As shown in FIG. In order to distinguish it from the fifth blowing air path 411 of Embodiment 1, in Embodiment 2, it demonstrates as 5th blowing air path 411C. The other configurations of the second embodiment are as described in the ...

Abstract

The refrigerator includes: a first storage room; a second storage room; a third storage room; a cooler installed on the rear side of the second storage room; part of the vacuum heat insulation; formed behind the vacuum heat insulation provided on the back of the third storage room, the first air path that guides air from the cooler into the second storage room; formed in the third storage room At the rear of the vacuum heat insulation element installed on the back, the air used in the second storage room is returned to the second air passage of the cooler; the air used in the third storage room is returned to the third air passage of the cooler through the return port, The first and second air passages are formed overlapping front and back, and are divided into two branches along the width direction of the vacuum heat insulating material. The air flowing in the air passage is introduced from the lower end of the vacuum heat insulating material, and the return port is formed below the vacuum heat insulating material.

Description

technical field [0001] This invention relates to the refrigerator which arrange|positioned the vacuum heat insulating material in each wall part which divides a storage room. Background technique [0002] In a conventional refrigerator, a refrigerating room, an ice making room, a freezing room, and a vegetable room are arranged in order from the top. In the case of this arrangement, the vegetable compartment is arranged at the lowest position of the refrigerator. Therefore, in order to take out vegetables from the vegetable compartment, the user needs to kneel down or bend down. [0003] Here, when comparing the number of times the door is opened and closed or the opening time of the door between the vegetable compartment and the freezer, although there are individual differences, the number of times the door of the vegetable compartment is generally opened and closed is relatively large, and the door opening time is also short. longer. Therefore, it is expected that the ...
