(4) Method of assembling the oxygen abatement apparatus 200

A method of assembling the oxygen abatement apparatus 200 will be described.

First, the oxygen abatement unit 202 having the pressure plate 222 is placed on the base plate 226, the water supply body 230 is laid on the oxygen abatement unit 202, the ventilation cover 236 is placed thereon, And is integrally fixed to the base plate 226 with screws (not shown) as shown in Fig.

Thirdly, as shown in Figs. 5 and 7, the CA fan 254 is fixed to the air supply duct 244.

Fourth, as shown in Fig. 3, a unit in which the base plate 226, the heat insulating cover 238 containing the oxygen abatement unit 202, the air supply duct 244, and the CA fan 254 are integrated , And the upper surface opening 140 (Fig. 8) of the oxygen reduction duct 138 by screws.

(5) Operation state of the oxygen abatement apparatus 200

Next, the operation state of the oxygen reduction apparatus 200 will be described.

When the refrigerator 10 is driven and the interior of the vegetable compartment 16 is cooled, air containing moisture flows into the vegetable compartment 16 as shown in FIG. Particularly, when the return air passing through the refrigerating chamber 14 and the vegetable chamber 16 is returned to the R room 27, the most moisture is contained. At the position where the return air containing this moisture passes, the oxygen abatement apparatus 200 is disposed. As shown in FIG. 5, the CA fan 254 blows the return air containing this moisture to the air inlet 240 through the air supply duct 244. In this case, since the bottom surface 252 of the air supply duct 244 is inclined toward the air inlet 240, it is possible to reliably send return air containing moisture.

8, the air including the water entered from the air inlet 240 of the heat insulating cover 238 passes through the ventilation path 256 inside the ventilation cover 236 and flows into the air outlet 242 And then discharged. At this time, as shown in Figs. 8 and 9, air containing moisture is introduced into the water supply body 230 below the air blowing cover 236, the silica gel 234 absorbs the water, (230). Then, the drained water passes through the pressure plate 222 to reach the water restriction film 224 (FIGS. 10 and 11) disposed under the pressure plate 222.

A necessary amount of water is permeated through the water restriction membrane 224 and water reaches the anode 208 through the slit-shaped opening 216 of the anode current collector 212. [ In this case, the water necessarily reaches the anode 208 by its own weight.

On the other hand, as shown in Fig. 9, food is contained in the oxygen abatement vessel 102 housed in the oxygen abatement chamber 100. [ The oxygen in the oxygen abatement chamber 100 is supplied to the cathode 210 of the oxygen abatement unit 202 through the oxygen reduction duct 138, the upper surface opening 140, and the opening portion 228 of the base plate 226 11).

When the food is stored in the oxygen reduction chamber 100, the control section of the control panel 26 starts energizing the anode current collector 212 and the cathode current collector 214. When the two current collectors 212 and 214 are energized, oxygen reduction reactions as shown in the following chemical formulas (1) and (2) are performed in the anode (208) and the cathode (210).

Figure 112015083144583-pat00001

Figure 112015083144583-pat00002

Describing the oxygen abatement reaction of the chemical formulas 1 and 2, the water reaches the anode 208 via the water restricting film 224 by its own weight. This water is electrolyzed in the anode 208 to form hydrogen ions (Proton H + ) (see Chemical Formula 1), the hydrogen ions move in the electrolyte membrane 206 to reach the cathode 210, And reacts with oxygen contained in the air introduced from the chamber 100 to generate water to consume oxygen (see Chemical Formula 2). Thereby, oxygen is reduced in the oxygen reduction chamber 100, and the food can be stored in the CA.

9, the water generated in the oxygen abatement unit 202 passes through the opening portion 228 of the base plate 226 and the upper surface opening portion 140 of the oxygen abatement duct 138, (138). The water dropped on the lower surface of the oxygen reduction duct 138 travels on the bottom surface 142 and reaches the bottom plate 112 of the oxygen reduction chamber 100.

(6) Effect

According to the present embodiment, as shown in Fig. 8, the CA fan 254 is connected to the inside of the vegetable compartment 16 containing moisture by the silica gel 234 of the water supply body 230 on the oxygen abatement unit 202 Air is supplied through the air supply duct 244 and the ventilation path 256 of the ventilation cover 236 so that the air containing moisture can securely reach the silica gel 234 and water can be supplied.

In addition, since the oxygen abatement unit 202 is arranged in the horizontal direction (horizontal direction) and the water supply body 230 having the silica gel 234 is provided thereon, the oxygen abatement unit 202 is smoothly Water.

The water generated in the oxygen abatement unit 202 is easy to fall downward, and the reaction is promoted. 9, the generated water passes through the bottom surface 142 of the oxygen reduction duct 138 and flows to the bottom plate 112 of the oxygen reduction chamber 100. [ Therefore, cleaning can be performed only by wiping off the water on the bottom plate 112 of the oxygen reduction chamber 100. The bottom surface 142 of the oxygen reduction duct 138 is located above the bottom plate 112 of the oxygen reduction chamber 100 so that the water in the oxygen reduction chamber 100 can flow into the oxygen reduction opening 136, And does not flow back to the oxygen reduction duct 138 from the oxygen reduction duct 138.

Since the oxygen abatement unit 202 is provided on the oxygen abatement duct 138 projected from the oxygen abatement chamber 100, the water produced during the oxygen abatement operation does not fall on the food contained in the oxygen abatement chamber 100 .

The oxygen reduction duct 138 protrudes from the back plate 114 of the oxygen reduction chamber 100 and the oxygen reduction unit 202 is attached to the oxygen reduction duct 138, The oxygen-abatement chamber 100 includes a back plate 114 and a plate-shaped oxygen abatement unit 202 which are disposed on the back plate 114 of the oxygen abatement chamber 100. More specifically, The heat generated in the oxygen abatement unit 202 is difficult to be transmitted to the inside of the oxygen abatement chamber 100 through the back plate 114, It does not affect the food inside the food container 100.

Since the upper portion of the oxygen abatement unit 202 is covered with the heat insulating cover 238, heat is hardly transmitted to the outside.

The oxygen reduction unit 200 is configured to be attached to the oxygen reduction chamber 100 as a unit integrally formed with the oxygen reduction unit 202, the water supply unit 230, the air supply duct 244, and the CA fan 254. Therefore, It is easy to carry out the production.

(7) Example of change

In the above embodiment, the bottom surface 142 of the oxygen reduction duct 138 is horizontal as shown in FIG. 9, but instead, as shown in FIG. 14, the bottom surface 142 of the oxygen reduction duct 138 is inclined downward toward the oxygen reduction chamber 100 So that water can flow more easily.

In the above embodiment, the oxygen abatement unit 202 is attached in the lateral direction, but may be attached in the longitudinal direction.

In the above-described embodiment, the case where the refrigerator has the oxygen abatement apparatus is described. However, the oxygen abatement apparatus of the present embodiment may be provided in the reservoir not provided with the cooling function.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other forms, and various omissions, substitutions, and alterations can be made without departing from the gist of the invention.
