Problems solved by technology

Therefore, if the thickness of the inner case becomes larger, the heat transfer efficiency of the cold energy from the cooling pipe arranged on the outer surface of the inner case to the regenerator decreases, and the freezing time of the regenerator becomes longer.
Therefore, there is a problem that the power consumption of the refrigerator becomes large.

[0037] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 , figure 2 and image 3 It is a front view, a side view, and a top view which show the refrigerator of 1st Embodiment. The refrigerator 1 includes: a main body 2 having a store room 20 with an open upper face; and an opening and closing door 3 (door) pivotally supported on the rear side of the main body 2 and opening and closing the upper face. The door 3 is opened and closed by holding the handle 3a provided on the front end.

[0038] A machine room 10 is provided at one end portion of the main body portion 2 . The machine room 10 has an opening (not shown) on the back and one side, and the opening is closed by a panel 11 having a vent hole 11a. A display panel 12 is provided on the front surface of the machine room 10 .

[0039] A lamp or the like is arranged on the display panel 12 , and the state of power supply to the refrigerator 1 and the temperature...

no. 2 approach

[0062] then, Figure 12 The front sectional view which shows the main-body part 2 of the refrigerator 1 which concerns on 2nd Embodiment. For the sake of illustration, with the Figure 1 to Figure 11 Like parts of the first embodiment shown are provided with the same reference numerals. In the present embodiment, cool storage bodies 30 are provided on two upper stages in store room 20 , and holding members 43 are provided between the cool storage bodies 30 on the upper and lower sides. Other parts are the same as the first embodiment.

[0063] The machine room 10 is provided at the lower part of one side end of the main body 2 , and the storage room 20 communicates with the side and the top of the machine room 10 . In the lower part of the storage room 20 , three regenerators 30 are arranged side by side on the front and rear inner surfaces, and two regenerators 30 are arranged side by side on the left inner surface along the front and rear directions. Since the cooling pa...

Abstract

A cooling box (1) comprises a main body unit (2) that has a storage chamber (20) the top surface of which is open and which is surrounded by thermal insulation walls, a door (3) that opens and closes the top surface of the storage chamber (20), a cooling unit (25) that is disposed in a side wall (20a) of the storage chamber (20) and that cools the storage chamber (20), a cold storing bodies (30) that have sealed therein a cold storing agent (31) that freezes due to cooling by the cooling unit (25), and retaining members (41, 42) that retain the cold storing bodies (30), wherein: the retaining members (41, 42) have a ring-shaped frame (45) that engages with the storage chamber (20), and have a support part (46) that is provided upright further towards the inner circumferential side than the outer circumferential edge of the frame (45); the cold storing bodies (30) are mounted on the frame (45) of one retaining member (41) that is disposed in the storage chamber (20), and the frame (45) of the other retaining member (42) is mounted on the top surface of the cold storing bodies (30); and the cold storing bodies (30) are retained between the side wall (20a) of the storage chamber (20) and the support part (46).

Description

technical field [0001] The present invention relates to a refrigerator provided with a cool storage body in which a cool storage agent is sealed. Background technique [0002] Patent Document 1 discloses a conventional refrigerator having a cool storage body. The refrigerated cabinet includes: a main body having a heat-insulating box forming a storage room with an open upper surface; and a door for opening and closing the upper surface of the storage room. The heat insulation box body is formed by filling foam insulation material between the inner box and the outer box, and the side wall and the bottom wall of the storage room are formed by the heat insulation wall. A cooling pipe connected to the compressor is embedded in the heat insulating wall, and the cooling pipe is arranged so as to be in contact with the inner box forming the inner surface of the storage room. [0003] A plurality of cool storage bodies are installed on the side wall of the storage room using an at...
