Hereinafter, the operation of the preferred embodiment of the storage box cold air supply structure for a refrigerator according to the present invention will be described in more detail.

First, in the preferred embodiment of the storage box cold air supply structure for a refrigerator according to the present invention will be described with reference to the accompanying drawings the process of mounting the vegetable box inside the box casing.

Figure 6 shows a process of mounting the vegetable box in the inside of the box casing in a preferred embodiment of the storage box cold air supply structure for the refrigerator according to the present invention.

As shown in FIG. 6, the vegetable box 60 is moved to the right in the drawing toward the inside of the mounting space 50S of the box casing 50. Therefore, the vegetable box 60 starts to be mounted in the mounting space 50S of the box casing 50 from the rear end thereof. At this time, the guide ribs 63 of the vegetable box 60 are guide rails, more specifically, between the upper guide rails 54a and the lower guide rails 54b by the support rollers 54r of the box casing 50. You are guided to space.

In addition, the guide rib 63 is guided to the space between the upper guide rail 54a and the lower guide rail 54b by the inclined guide portion 54d of the upper guide rail 54a. Therefore, the storage box 60 is installed in the box casing 50 at the position where the guide rib 63 does not exactly match the space between the upper guide rail 54a and the lower guide rail 54d. The guide rib 63 is guided into the space between the upper guide rail 54a and the lower guide rail 54b by the inclined guide part 54d even though the guide rib 63 is moved toward the inside. Is prevented from being incorrectly mounted in the mounting space 50S of the box casing 50.

Meanwhile, when the vegetable box 60 is continuously moved to the inside of the mounting space 50S of the box casing 50, that is, to the right in the drawing, the guide rib 63 slides along the guide rail. As shown in FIG. 5, when the vegetable box 60 is mounted in the mounting space 50S of the box casing 50, the rear surface of the engaging flange 61 of the vegetable box 60 is the box casing ( 50) is in close contact with the front of the contact flange (51a). Therefore, the vegetable box 60 is not completely entered into the mounting space (50S) of the box casing (50).

Next, a state in which cold air flows in a preferred embodiment of a storage box cold air supply structure for a refrigerator according to the present invention will be described with reference to the accompanying drawings.

As shown therein, the cold air supplied from the cold air supply port 33a of the cold air duct 33, that is, the cold air of the freezing chamber is transferred into the flow path 50P through the cold air inlet 50i. The cold air delivered into the passage 50P is circulated inside the passage 50P and then discharged to the outside of the passage 50P through the cold air outlet 50o.

At this time, the cold air delivered into the passage 50P is guided by the cold guide 58. That is, the cold air transferred into the flow path 50P through the cold air inlet 50i is guided by the first guide part 58a of the cold guide 58 toward the right end of the flow path 50P. It flows and is guided by the second guide portion 58b of the cold guide 58 again and flows from the right end to the left end on the drawing of the flow path 50P. The cold air guided by the second guide part 58b and flown to the left end in the drawing of the flow path 50P is connected to the flow path 50P by the third guide part 58c of the cold guide 58. It is guided to flow toward the left rear end, ie, the cold air outlet 50o, in the figure.

The cold air flowing toward the cold air outlet 50o is discharged to the outside of the flow path 50P, that is, the inside of the refrigerating chamber 31 through the cold air outlet 50o. And it is transmitted to the evaporator through the cold air return port of the refrigerating chamber 31.

Meanwhile, the food stored in the storage space 60S of the vegetable box 60 mounted in the mounting space 50S of the box casing 50 is indirectly cooled by cold air circulating inside the flow path 50P. Therefore, the odor of other foods stored in the refrigerating compartment 31 in the food stored in the storage space (60S) of the storage box 60 is prevented, or the phenomenon that the water contained in the food evaporates or weakly cooled or overcooled.

Within the scope of the basic technical spirit of the present invention as well as many other modifications are possible to those skilled in the art, the scope of the present invention should be interpreted based on the appended claims. .

According to the refrigerator storage box cold air supply structure according to the present invention configured as described above is expected the following effects.

According to the present invention, the food stored in the storage box is indirectly cooled by the cold air flowing through the flow path provided in the box casing. Therefore, the odor of other foods stored in the refrigerating chamber or the moisture of the food may be prevented from being evaporated to the food stored in the storage box. Food stored in the box can be stored fresher for a long time.

In the present invention, a cold air supply port for supplying cold air to the refrigerating chamber is in direct communication with the cold air inlet of the flow path. Therefore, since a separate configuration for supplying cold air to the flow path is not required, the food stored in the storage box can be kept fresh.

In the present invention, the storage box mounted on the box casing is guided by guide means. Therefore, the storage box can be more easily mounted at the correct position of the box casing.
