no. 1 approach

[0029] Below, according to Figure 1 to Figure 4 , the refrigerator 10 of the first embodiment will be described.

[0030] (1) Structure of refrigerator 10

[0031] First, according to figure 1 and figure 2 , the structure of the refrigerator 10 will be described.

[0032] The housing 12 of the refrigerator 10 combines an outer box and an inner box, and an unillustrated heat insulating material is arranged between the outer box and the inner box, such as figure 2 As shown, it is divided into a refrigerator compartment 14, a vegetable compartment 16, an upper freezer compartment 18, and a freezer compartment 20 from the upper stage, and an ice making compartment 22 is provided on the left side of the upper freezer compartment 18.

[0033] Between the vegetable compartment 16, the upper freezer compartment 18, and the ice-making compartment 22, an insulating partition wall 24 is arranged, and the refrigerating compartment 14 and the vegetable compartment 16 form a refriger...

no. 2 approach

[0080] Next, regarding the refrigerator 10 of the second embodiment, based on the fact that the same symbols are attached to the same components as those of the first embodiment, Figure 5 Be explained.

[0081] The difference between the present embodiment and the first embodiment lies in the drainage structure of water in the connection member 60 .

[0082] In this embodiment, the bottoms of the rear connecting portion 62 and the front connecting portion 64 of the connecting member 60 are formed in a cross-sectional funnel shape with the middle portion being the lowest, and a hole 76 is opened in the center.

[0083] One end of a pipe 78 is connected to this hole 76 , and the other end of the pipe 78 is connected to an evaporating pan 80 for evaporating defrosting water in the refrigerator 10 . Furthermore, a water absorbing member 82 is inserted into the hole 76 . The water absorbing material 82 has a wedge shape formed so as to protrude downward.

[0084] In the present...

no. 3 approach

[0086] Next, regarding the refrigerator 10 of the third embodiment, based on the fact that the same symbols are given to the same components as those of the first embodiment, Figure 6 Be explained.

[0087] The difference between the present embodiment and the first embodiment lies in the method of treating the water generated by the adjustment device 58 .

[0088] In this embodiment, the bottom surface of the connection member 60 is made flat, water is stored in the flat portion, and the water is evaporated. Since the amount of water generated by the adjusting device 58 is small, even if the water is stored on the bottom surface of the connection member 60 and evaporates, it will not flow out to the lower container 48 .

Abstract

Provided is a refrigerator, for which water generated in a process of depetion oxygen can not penetrate into a container inner part for storing foodstuff. The refrigerator is provided with a vegetables chamber (16); a lower container (48) capable of being closed; an oxygen concentration adjusting device (58) which changes oxygen in the inner of the lower container into water to reduce oxygen concentration and a connecting component (60) connected between the lower container (48) and the oxygen concentration adjusting device (58) to prevent the generated water from flowing into the lower container (48).

Description

technical field [0001] Embodiments of the present invention relate to refrigerators. Background technique [0002] Conventionally, by replacing the composition of the air, a refrigerator provided with a controlled-atmosphere storage room that performs controlled-atmosphere (Controlled Atmosphere) storage that better maintains the freshness of food has been proposed (for example, refer to Patent Documents 1 to 3 ). [0003] Among the methods of controlled atmosphere storage, there are the following methods: the gas exchange method that is widely used in the food industry, the vacuum method that reduces oxygen by reducing pressure, and the use of polymer electrolyte membranes to reduce the high temperature of oxygen without changing the gas pressure. Molecular electrolyte membrane method, and adsorption method using oxygen adsorbent, etc. [0004] The gas replacement method replaces nitrogen or carbon dioxide gas with air for storage. It is widely used to maintain freshness ...
