1 and 2 are a perspective view showing a refrigerator according to the present invention, Figure 3 is a horizontal cross-sectional view showing a refrigerator according to the present invention, Figure 4 is a vertical cross-sectional view showing the cold air flow of the refrigerator according to the present invention.

In the refrigerator according to the present invention, as shown in FIGS. 1 and 2, a hollow passage 203 is formed in the longitudinal direction therein, and a plurality of channels 201 extending in the longitudinal direction are formed on the outer circumferential surface thereof. The inner cylinder 200 formed at intervals along the direction and in close contact with the outer circumferential surface of the inner cylinder 200 to form a passage between the channel 201 and communicate with the hollow of the inner cylinder 200 A central shaft 20 formed of an outer cylinder 210 having a cold air discharge unit 220 and a cold air return unit 230 communicating with the channel 201 is fixed to the center of the refrigerator body.

In addition, the outer cylinder 210 has a plurality of shelves 30 are arranged at a predetermined interval to intersect on the central axis 20, the outer cylinder 210 and the shelf 30 or the housing 40 Bearings (not shown) are provided therebetween so that only the shelf 30 rotates about the central axis 20 with respect to the outer cylinder 210.

On each shelf 30 is provided a storage compartment 400, which is a space for storing food, and a housing 40 constituting the refrigerator body.

Here, the plurality of shelves 30 are rotatable, respectively, so that each storage compartment 400 is rotatable separately.

The storage compartment 400 provided as described above may be operated as, for example, a freezer compartment, a refrigerator compartment, a vegetable compartment, and the like, and at least two or more doors 410 are formed on the front surface of the housing 40 at regular intervals.

Here, the door 410 is a sliding door or a sliding door type, but is not limited to this, the door shape as described above is just one example that can be applied to the present invention, various shapes may be adopted and mounted.

On the other hand, the lower portion of the storage compartment 400 is usually equipped with a cooling device, such as a compressor, a condenser, an evaporation name, the machine room 50 is provided. Here, the machine room 50 is made so as not to rotate unlike the storage room 400.

In addition, as illustrated in FIG. 2, an air blower guiding the evaporator 11 and the cool air generated in the evaporator 11 to the passage 203 of the inner cylinder 200 in the upper portion of the central shaft 20. The case 10 in which the fan 12 is installed is provided.

The case 10 is installed to be sealed on the outer cylinder 210 of the central axis 20 in the shape of a circular cylinder is sealed in the upper bar, the inner wall 100 extending from the inner cylinder 200 and , A double wall structure of the outer wall 110 extending from the outer cylinder 210.

Accordingly, the cool air generated in the evaporator 11 in the case 10 is lowered through the passage of the inner cylinder 200, so that the cool air flowing through the inner cylinder 200 can be guided to the storage compartment 400. The duct-shaped cold air discharge unit 220 connected through the outer cylinders 200 and 210 is provided at the upper portion of the central shaft 20 provided in each storage chamber 400.

That is, the cold air discharge unit 220 is preferably a hole passing through the outer protruding surface 202 between the channel 201 and the channel 201 of the inner cylinder 200 and the outer cylinder 210 in close contact therewith. Do.

The channel of the inner cylinder 200 may be circulated through the channel 201 which is a passage between the inner and outer cylinders 200 and 210 through the cold air discharge unit 220. The cold air return unit 230, which is a hole penetrating 201 and the outer cylinder 210, is provided below the central axis 20 provided in each storage chamber 400.

That is, the cold air discharged from the cold air discharge unit 220 to the upper portion of the storage compartment 400 descends due to convection in the storage compartment 400 and then flows into the channel 201 through the cold air return unit 230. Will rise.

As described above, the cold air introduced through the cold return unit 230 and raised through the channel 201 is allowed to flow back into the inner cylinder 200.

To this end, a ring-shaped loop plate 240 blocking the upper portion between the inner and outer cylinders 200 and 210 is coupled through a vertical coupling surface 241, wherein the roof plate 240 is the outer portion. Cold air guide holes 241a are formed in the vertical coupling surface 241 to guide cold air from the cylinder 210 to the inner cylinder 200.

That is, the roof plate 240 is returned through the channel 201 between the inner and outer cylinders 200 and 210 so that the cooled cold air is smoothly guided to the passage 203 of the inner cylinder 200. The cold air guide hole 241a is formed in the 241.

In addition, the roof plate 240 guides the defrost water generated from the inner wall 100 outside the case 10 by the evaporator 11 to the machine room 50 through the channel 201 on an upper surface thereof. Defrost water guide hole 241b is formed.

Accordingly, the defrost water generated in the case 10 is guided to the evaporation name of the machine room 50 through the defrost water guide hole 241b of the roof plate 240, and through the cold air return unit 230. The cold air flowing into the upper portion of the central shaft 20 is lowered back into the passage of the inner cylinder 200 through the cold air guide hole 241a.

In particular, the roof plate 240 is formed with a 'V' type cross-sectional groove 242 at a position close to the defrost water guide hole 241b so that the defrost water can be easily collected toward the defrost water guide hole 241b.

As a result, the cool air generated inside the case 10 circulates while circulating the inner cylinder 200, the storage chamber 400, and the outer cylinder 210 of the central shaft 20 in order to lower the temperature of the storage chamber 400. It is possible to maintain, the defrost water generated in the case 10 can be easily flowed to the evaporation name of the machine room 50 through the channel 201 of the central axis (20).

Therefore, according to the present invention, the shelf 30 of the storage compartment 400 is rotatable about the central axis 20, and the shelf 30 is configured to store food on the shelf 30 so as to select food desired by the user. Rotating the 30 to open the door 410 can be easily taken out.

In addition, since the entire storage compartment 400 is rotated, since the cold air discharged from the central axis 20 into the storage compartment 400 is uniformly supplied to the entire interior of the storage compartment 400, the food can be evenly exposed to the entire food being stored. It will not easily rot.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Various modifications to the embodiments are also within the scope of the claims of the present invention.
