Next, the flow of cold air in the refrigerator compartment 8, the vegetable compartment 9, and the bottle compartment 10 will be described.

Part of the cold air diverted in the thermopat 20 is discharged from the rear into an ice temperature chamber 22 provided at the upper part of the refrigerator compartment 8,
After cooling the inside of the ice temperature room 22, it is discharged into the refrigerator room 8 from the front of the ice temperature room 22, and descends in the same room. On the other hand, the cool air discharged from each of the shelves from the refrigerator compartment discharge port 21d cools the space between the shelves and then descends in the refrigerator from the front of the shelves. The cold air that has fallen enters the vegetable compartment 9 through the cold room cold air return port 29a provided in the cold room bottom plate 29. Some of the cold air in the ventilation duct 21 is
Is discharged directly to the rear of the vegetable compartment 9 from the vegetable compartment discharge port 21e. Therefore, the vegetable room 9 is provided with a relatively low temperature cool air discharged from the vegetable room discharge port 21e and a relatively high temperature cool air entering from the cold room cool air return port 20a. It is designed to cool indirectly.

All the cool air that has cooled the vegetable compartment 9 passes through the vent 33, is introduced into the bottle compartment 10, cools the bottle case 32 from the surroundings, and then cools through the suction port 34 provided at the upper rear of the bottle compartment 10. It returns to the inside of the instrument room 11.

Further, part of the cool air in the ventilation duct 21 is not discharged to the refrigerator compartment 8 and the vegetable compartment 9, and
8, is discharged directly into the bottle case 32 through the bottle room through-hole 27, the bottle room ventilation passage 25 and the bottle room discharge port 26, and cools the inside of the bottle case 32, and then cools the above-mentioned refrigerator compartment 8, vegetable compartment 9 Like the later cool air, it returns to the inside of the cooler room 11 via the suction port 34.

Since the refrigerator of the present embodiment is configured as described above, the freezer compartment 7 and the refrigerator compartment 8 are juxtaposed at the upper part, the drawer-type bottle compartment 10 is provided below the freezer compartment 7, and the lower part of the refrigerator compartment 9 is provided. Since the drawer-type vegetable room 9 is installed in each room and each room is independently configured for each application, the usability is further improved.

Generally, the set temperature of the above four chambers is -18
The temperature in the refrigerator room is 3 ° C., the temperature in the vegetable room is 4 ° C., and the temperature in the bottle room 10 is relatively high at approximately 6 ° C. in consideration of the temperature of drinking beer or the like. Focusing on this point, the arrangement of each room of the refrigerator of the present embodiment is configured as described above,
By circulating in the order of the set temperature from the vegetable room 9, the bottle room 10 to the bottle room 10, cooling can be made as a ventilation passage in each room. Therefore, the cooling air circulation path of each room is formed only by penetrating the two places of the refrigerator room ventilation path 18 and the ventilation opening 32, so that the ventilation duct and the suction duct for each room are formed into a box like a conventional refrigerator. There is no need to bury it in urethane, the number of parts is small, the cost is advantageous, and a highly reliable refrigerator free from performance variations due to urethane leakage or the like is provided.

In addition, the cool air in the ventilation duct 21 is directly
Through the bottle penetration 27, bottle room ventilation path 25,
Since air is directly blown into the bottle chamber 10, particularly when it is desired to lower the temperature of the bottle chamber 10, the temperature can be set to an arbitrary temperature by changing the passage area.

Furthermore, since the bottle room duct 28 is installed in the rear projection of the horizontal partition plate 6, that is, between the refrigerator room bottom plate 29 and the vegetable case lid 31, the bottle room duct 28 is not exposed in the refrigerator. , Which are covered in design. In this installation place, the vegetable case 30 is a drawer type, so what was previously an ineffective volume that could not be used for food storage was effectively used for ventilation, and the bottle room duct 28 The installation does not reduce the effective internal volume in the refrigerator.

Further, the cold air that has cooled the refrigerator compartment 8 flows into the vegetable compartment 9 from the refrigerator compartment cold air return port 29a provided in front of the refrigerator compartment bottom plate 29, and this cold air has a very small gap between the vegetable case lid 31 and the horizontal partition plate 6. Since it is set small, as shown by the arrow in FIG. 4, it flows backward on the upper surface of the vegetable case lid 31 and mixes with the relatively low-temperature cool air discharged from the vegetable room discharge port 21e at the lower end of the ventilation duct 21. 30 from the bottom to the bottom, and finally from the ventilation opening 33 near the door to the bottle room 10
It is flowing to. Therefore, the vegetable case 30
As the cool air circulates uniformly from the surroundings and cools efficiently, the temperature distribution inside the vegetable case 30 becomes uniform, only the low-temperature cool air is concentrated at the rear of the vegetable case 30, and the vegetables near the inner rear wall freeze. Don't worry. Further, the cool air entering from the ventilation port 33 flows from the front to the rear in the bottle chamber 10 and returns to the rear suction port 34, so that a uniform temperature distribution can be obtained as in the vegetable chamber 9.

In addition, since the cooler chamber side outlet portion 34a of the suction port 34 is set at a position higher than the freezing chamber suction port 15b, when the refrigeration cycle is stopped, the cool cool air around the cooler 12 falls by its own weight, so-called Although a backflow phenomenon may occur, even at this time, since the cold air flows back into the freezing room 7 from the freezing room suction port 15b located at a low position, the cold air flows back into the bottle room 10 and the bottles are frozen. Preventing.

As described above in detail, the refrigerator of this embodiment is
The compartment is divided into four compartments, and the upper compartment is a freezer compartment,
A refrigerator and a cooling fan are housed at the back of the freezing room, a bottle room is provided at the lower part, and a refrigeration room is provided at the side. A lower part of the refrigeration room is used as a vegetable room. Because of the circulation, each chamber can be made independent and easy to use, the ventilation duct can be formed with a minimum number of parts, and the air volume of each chamber can be easily adjusted.

Further, since the bottle room duct is installed in the rear projection of the horizontal partition plate, the temperature of the bottle room can be arbitrarily selected, and the effective internal volume does not decrease due to the installation of the duct.

Further, by providing the ventilation opening in the vertical partition wall near the door, it is possible to provide a refrigerator having an excellent structure such that the temperature distribution before and after the vegetable room and the bottle room can be made uniform.

〔The invention's effect〕

As described above in detail, according to the present invention, it is possible to provide a refrigerator in which the structure for ventilating the air into the storage room is simplified and the temperature of each room can be easily adjusted.
