Abstract

PURPOSE:To simultaneously realize optimum temperature of a vegetable chamber and other cooling chambers downward thereof by allowing the cold storage to blow off cold which is not heat-exchanged with foods in the lower part rearward of the vegetable chamber through a private duct, permitting this to join to cold heat-exchanged with vegetables in other passages and allowing joined cold to introduce in the cooling chamber through through holes drilled in a partition plate. CONSTITUTION:Whole the cold which is not blown off through a louver 44 in the part of the upper part 4b of a cold storage chamber of a left duct 32 provided in the rear part in the chamber of the right side part of a refrigeration chamber 4 is blown off in the lower part rearward of a vegetable chamber 5 through an opening provided at the lower end 40 of an extension duct 38. In addition, the cold which is heat-exchanged with vegetables through a vessel 72 while the cold descends from through holes 66 of a lower partition plate 58 flows in a bottle chamber 6 through the through holes 68 of the lower partition plate 60. Since the cold which is sent out in the lower part rearward of the vegetable chamber 5 is not heat-exchanged with either of foods, the temperature is lower than the cold heat-exchanged with the vegetables through the vessel 72. The cold of low temperature is allowed to join to the cold descending from the upper part thereof in a lower duct 79 to flow in the bottle chamber 6 through the through holes 68 of the partition plate 60.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a refrigerator in which another cooling compartment such as a bottle compartment is arranged below a vegetable compartment.

(Prior Art and Problems to be Solved by the Invention) When a refrigerator is provided with a dedicated bottle chamber for storing bottled beer, etc., it is preferable to provide this at the bottom of the refrigerator due to weight considerations. Therefore, when a vegetable compartment is provided in addition to the bottle compartment, the vegetable compartment is provided above the bottle compartment.

Now, in conventional refrigerators, a fan blows out cold air from the top of the refrigerator, and the cool air is lowered from the upper chamber to the lower chamber, and then the fan sucks up the cold air from the bottom.

By the way, it is optimal to adjust the temperature of the vegetable compartment to about 7°C and the bottle compartment to a lower temperature of about 5°C. However, even if the bottle compartment is arranged below the vegetable compartment, which is the room with the highest temperature in the refrigerator, if the cold air inside the refrigerator is sent from top to bottom as before, the cold air whose temperature has increased by exchanging heat with the vegetables. flows into the bottle compartment, so the temperature in the bottle compartment becomes higher than the temperature in the vegetable compartment. Therefore, there is a problem in that when the vegetable compartment is set at an appropriate temperature, the bottle compartment temperature becomes too high, and when the bottle compartment is set at an appropriate temperature, the vegetable compartment temperature becomes too low.

The present invention has been made in view of the above points, and an object of the present invention is to simultaneously realize the optimum temperature of both chambers in a refrigerator in which another cooling chamber such as a bottle chamber is arranged below the vegetable chamber.

[Structure of the Invention] (Means for Solving the Problems) The refrigerator according to the present invention is such that the lower part of the vegetable compartment for storing vegetable containers is partitioned off with a partition plate to form another cooling compartment such as a bottle compartment. Then, the cold air that has not exchanged heat with the food is blown out into the rear lower part of the vegetable compartment through a special duct, and is combined with the cold air that has been introduced into the vegetable compartment through another route and has exchanged heat with the vegetables through the container. The cooling air is introduced into other cooling chambers such as bottle chambers through through holes provided in the partition plate.

(Function) The cold air blown into the rear lower part of the vegetable compartment through the dedicated duct does not exchange heat with any food, so its temperature is lower than the cold air that exchanges heat with the vegetables in the vegetable compartment through the containers.

This low-temperature cold air joins with the cold air coming down around the vegetable container, and flows into other cooling chambers such as the bottle chamber through the through holes in the partition plate. Therefore, the temperature of this cooling compartment will be lower than the vegetable compartment temperature.

A looper 48 is formed in the right duct 48 only at the front portion inside the chilled room 4a, and all of the cold air supplied into the right duct 48 is blown out into the chilled room 4a.

On the other hand, no looper is formed between the chilled room 4a portion of the left duct 32 and the extension duct 38, and all of the cold air that is not blown out through the looper 44 in the upper portion 4b of the refrigerator compartment of the left duct 32 is transferred to the extension duct. It is blown out to the rear lower part of the vegetable compartment 5 through an opening provided at the lower end 40 of the vegetable compartment 5 .

FIG. 1 is a lower vertical sectional view of the right side portion of this refrigerator 1.

The refrigerator main body 8 having a front opening has a vertical back plate 52 and a bottom plate 54 following the vertical back plate 52. On the right side of the refrigerator main body 8, a bar-shaped upper and lower partition 56.
57 is fixed horizontally. These upper and lower partitions 56.5
Upper and lower partition plates 58 and 60 are disposed behind the refrigerator 7, respectively, and the inside of the refrigerator main body 8 is divided into the refrigerator compartment 4, the vegetable compartment 5, and the bottle compartment 6 in order from the top, as described above. However, directly above the chief cutting board 58 is the child room 4a.

A through hole 66 is provided at the front edge of the main cutting plate 58,
This main cutting board 58 passes through the through hole 66 into the child room 4a.
It has the function of introducing cold air into the vegetable compartment 5, and is also used, for example, as a bottom plate of an inner dish. Upper partition plate 6
A through hole 68 for supplying cold air from the vegetable compartment 5 to the bottle compartment 6 is provided a little further forward in the longitudinal direction of the container 0. The vegetable container 72, which has only its top open, is detachably held by a U-shaped holding member 74 fixed to the rear surface of the vegetable compartment door 15, and can slide back and forth together with the vegetable compartment door 15.

An elastic plate-like cover 76 is fixed almost horizontally between the vegetable container 72 and the main cutting plate 58, and when the vegetable compartment door 15 is closed, the cover 76 covers the top surface of the vegetable container 72. close. With the above arrangement, the area around the vegetable container 72 uses the through hole 66 provided at the front edge of the main cutting plate 58 as an inlet, and the through hole 68 of the upper partition plate 60 arranged below the vegetable container 72 as an inlet. A vegetable compartment cold air duct is formed as an outlet. That is, this duct includes a horizontal upper duct 77 between the main cutting plate 58 and the cover 76, and a rear plate of the vegetable container 72 and the back plate 5.
2 and each front surface of the extension duct 38, and a horizontal lower duct 79 between the bottom plate of the vegetable container 72 and the upper partition plate 60. Furthermore, vegetable container 7
Side ducts (not shown) are formed along the left and right side plates of 2. However, the front plate of the vegetable container 72 is substantially in close contact with the rear surface of the vegetable compartment door 15, and no cold air duct is formed at this position.

The bottle container 80 with its top open is removably held by a U-shaped holding member 82 fixed to the rear surface of the bottle chamber door 16, and can slide back and forth together with the bottle chamber door 16. A large number of slits 84 are provided on the front plate of the bottle container 80. In addition, bottle compartment 6 and freezer compartment door 1
A return duct 8B is provided on the partition wall between the lowermost part of the left side section blocked by the second freezer compartment and the second freezer compartment.
The lower part of the cooler chamber formed at the back of the freezing chamber and the bottle chamber G are communicated through a return duct 86.

Air that has exchanged heat with a cooler (not shown) in the left side of the refrigerator 1 is sent out by a fan (also not shown) disposed at the top. A portion of the cold air sent out passes through the doors 11 and 12.
．． It circulates in the left part through the freezer compartment closed at 13, the ice making compartment and the second freezer compartment. The other part of the cold air sent out by the fan is separately blown out to the upper part 4b of the refrigerator compartment 4 and the chilled room 4a through the damper box 20 and the rear duct 22. Thereby, for example, the temperature of the upper part of the refrigerator compartment 4b is adjusted to 3°C, and the temperature of the chilled room 4a is adjusted to 0°C.

The cold air introduced into the upper and lower parts of the refrigerator compartment 4 exchanges heat with the food, and then merges in this compartment and passes through the main cutting plate 58.
It flows into the vegetable compartment 5 through a through hole 66 provided at the front edge of the vegetable compartment 5. The cold air flowing into the vegetable compartment 5 flows through an upper duct 77, a rear duct 78, a side duct, and a lower duct 7 formed around the vegetable container 72 whose top surface is closed with a cover 76.
9 in sequence. Therefore, the vegetable container 72 itself is sufficiently cooled.

In other words, the vegetables stored in this container 72 are cooled under high humidity by the moisture evaporated from themselves.

The temperature of this vegetable compartment 5 is, for example, 7°C. This results in
Vegetables can be preserved without losing their freshness. The cold air, which exchanged heat with the vegetables through the container 72 while coming down from the through hole 6B of the main cutting plate 58, flows into the bottle chamber 6 through the through hole 6B of the upper partition plate 60.

Now, since the cold air sent to the rear lower part of the vegetable compartment 5 through the opening provided at the lower end 40 of the extension duct 38 does not exchange heat with any food, it is stronger than the cold air that exchanged heat with the vegetables via the container 72. Temperature is low. This low-temperature cold air joins with the cold air coming down from above in the lower duct 79 and flows into the bottle chamber 6 through the through hole 68 of the upper partition plate 60.

Therefore, the temperature of the bottle compartment 6 is lower than the temperature of the vegetable compartment 5, for example, 5°C, which is suitable for storing bottled beer. The cold air that has flowed into the bottle container 80 is led out from this container through the slit 84, and is introduced from the bottle chamber 6 through the return duct 86 to the lower part of the cooler chamber formed at the back of the second freezing chamber in the left side portion of the refrigerator 1. After being cooled in the cooler, it is circulated inside the refrigerator again.

[Effects of the Invention] As explained above, the refrigerator according to the present invention is one in which the lower part of the vegetable compartment housing vegetable containers is cut off with a partition plate to form another cooling compartment such as a bottle compartment. , Cool air that has not exchanged heat with the food is blown into the rear lower part of the vegetable compartment through a dedicated duct, and is combined with the cold air that has been introduced into the vegetable compartment through another route and has exchanged heat with the vegetables through the container. Since the cold air is introduced into other cooling chambers such as the bottle chamber through the through holes provided in the partition plate, the temperature of this cooling chamber cannot be controlled even though the other cooling chamber is arranged below the vegetable compartment. The temperature can be lower than that of the vegetable compartment, making it possible to achieve the optimum temperature in both compartments at the same time.
