Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a refrigerator in which cooled air is blown to a cold air discharge damper in a refrigerator compartment using an internal circulation blower. To provide a refrigerator in which a large number of produced parts are controlled in rooms having different temperature ranges.

[Background of the invention]

Conventionally considered as this kind of refrigerated storage, there is a refrigerator in which the refrigerating room is divided into a cold room, a cold room, and a vegetable room using simple partition boards, and doors are installed in these partitioned rooms. . This refrigerator has a duct on the back of the inner box (insulating material 1111) that connects the above room and the cold air outlet to the refrigerator compartment, and a damper that adjusts the amount of cold air in the duct, so that each room can be divided into different temperature zones. This is what was done. Refrigerators with such a configuration have the advantage of being able to control the temperature within a relatively narrow range of m degrees.
However, in addition to the need for partition plates to separate each room, a duct was required to be installed on the back of the inner box, and a damper for temperature control was also required, which resulted in higher costs.

In addition, examples related to this type of refrigerator include:
There is a publication of Publication No. 59-1190.
゛ [Object of the invention] The present invention is a cause of the above-mentioned cost increase. □
``Without the use of partition plates, ducts, cold air dampers for temperature control, etc., the cold air released into the refrigerator compartment is guided to each room using a concave duct formed on the back of the inner box, and each room is heated to a different temperature. It was designed to be a obi room.

[Summary of the invention]

That is, the present invention provides a refrigerator in which chilled cold air is blown to a cold air damper in the refrigerator compartment using an internal circulation blower, and is provided with an ice-temperature chilled compartment, a refrigerated chilled compartment, and a vegetable chilled compartment formed in the lower part of the refrigerator compartment. The chamber is formed of a resin container, and a glass plate is interposed between the containers.

[Embodiments of the invention]

Hereinafter, details of the present invention will be explained with reference to an embodiment shown in FIGS. 1 and 2. Reference numeral 1 denotes a refrigerator main body, and the main body 1 includes a freezer compartment 2 and a refrigerator compartment 3 that are cooled to around -18°C. It has 4.5.6 shows an ice-temperature chilled compartment 4, a refrigerated chilled compartment 5, and a vegetable compartment 6, which are formed in this order in the refrigerator compartment 3. 7 indicates the freezer compartment door, and 8 indicates the refrigerator compartment door. Further, 9 indicates the ice-temperature chilled compartment 4, 10 indicates the refrigerated chilled compartment 5, and 11 indicates the vegetable compartment 6. The door 7.8 thus typically rotates around a hinge mounted at one corner. And h9.10.
11 is of a drawer type. In other words, this Guo 9
．． 10.11 is the above-mentioned ice temperature chilled room 4, refrigerated chilled room 5,
It is equipped with containers 12, 13, 14 for forming the vegetable compartment 6, and pulling out the door 9, 10, 11 means that the compartment 4.5
．． This means pulling out 6. 15 is a cooler, and 16 is a blower that forcibly circulates cold air cooled by the cooler 15 to the freezer compartment 2 and refrigerator compartment 3. Reference numeral 17 denotes a temperature regulating cold air damper provided at the cold air outlet of the refrigerator compartment. 18.1
9 is an inner box 1 that forms a refrigerator compartment 3 and an ice-temperature chilled compartment 4, etc.
This is a cold air duct formed by recessing the portion a toward the heat insulating material 20 side. The cold air ducts 18, 19 are integrally formed during vacuum forming of the inner box 1a. The upper end of the cold air duct 18, 19 faces the outlet ports 17a, 17b of the cold air damper 17, and the lower end of the cold air duct 18 is connected to the ice temperature chilled chamber 4, and the lower end of the cold air duct 19 is connected to the refrigerated chilled chamber 5. Each corresponds to vegetable compartment 6.

Further, the front surface of the cold air duct is formed by the back walls 12a, 13a of the container 12.13 listed above.

18a, 19a, 19b are cold air guiding noses provided at the final end of the duct 18.19, which effectively guide the cold air guided from the duct 8.19 into the container 4.5.6. 21 is a partition plate that divides the ice-temperature chilled compartment 4 of the refrigerator compartments 3 and 4.

In place of this partition plate, glass plates 29 and 30 are provided between the ice-temperature chilled compartment 4, the refrigerated chilled compartment 5, and the vegetable compartment 6. The containers 12 and 13 that form the ice-temperature chilled compartment 4 and the refrigerated chilled compartment 5 have a role of closing the openings at the bottom like the partition plate 21, or when the refrigerated chilled compartment 5 is switched to the vegetable compartment 6, etc. In order to prevent dew from forming on the bottom surface, the above glass plate 2
9 and 30 are provided. Reference numeral 22 denotes a partition member that serves as a contact surface between the refrigerator compartment door 8 and the gasket (not shown) of the ice-temperature chilled compartment 4. Reference numeral 23 denotes a partition member that serves as a contact surface between the gaskets (not shown) of the refrigerated chilled chamber 5 and the frozen chilled chamber 4. In addition, the lid 10 of the refrigerated chilled compartment 5 and the packing of the door 11 of the vegetable compartment (
A sealing structure is achieved by joining both doors without providing any particular partition member that comes into contact with the door (not shown).

In the case of the refrigerator of the present invention formed as described above, the freezer compartment 2 includes the fan guard 246 and the discharge port 2, as in a general refrigerator.
The freezing chamber 2 is cooled to a predetermined temperature in the process in which the cold air blown out from the air inlet 5 is sucked into the suction port 26. On the other hand, the refrigerator compartment and the many chambers formed within this compartment are cooled in the following manner.

That is, the refrigerator compartment 3 is connected to the cold air duct 18 by a part of the cold air damper.
A part of the cold air blown towards the refrigerator compartment 19 is routed to the refrigerator compartment, and the ice-temperature chilled compartment 4 is supplied with the cold air guided to the cold air duct 18. They are cooled by the cold air guided by them. At this time, the duct 19 is branched in the middle as shown in FIG. 2 to cool the refrigerated chilled compartment 5 and the vegetable compartment 6. In this way, the cold air led to each chamber forms a cold air circulation path as shown by the arrow, and returns to the cooler 15 through the cold air suction port 28 provided in the partition wall 27.

In this process, in the present invention, the temperature can be controlled without providing special ducts in the cold air duct sections 18 and 19 by selecting the size and shape of the cold air duct passages in advance. This sets the room to the required temperature. As a means of changing the resistance of this ventilation path, it is effective to utilize the gap between the rear end of the glass plate and the back surface of the inner box 1a described above.

Also, the back walls 12a, 13a of the container 12.13 and the duct 18
．． The dimensions between 19 and 19 may be varied. By taking these measures, the cold air discharged from the cold air damper 17 in the refrigerator compartment 3 is blown out in a predetermined amount not only to the refrigerator compartment 3 but also to the ice-temperature chilled compartment 4, the chilled refrigerator compartment 5, and the vegetable compartment 6. The above-mentioned chambers can be maintained at set temperatures, for example, the ice temperature chilled room at -1°C, the refrigerated chilled room at +3°C, and the vegetable compartment 6 at +6°C.

In addition, as shown in Fig. 2, the lower end of the cold air duct 18, 19 (
If the cool air guide nose section is formed into a fan shape, the air will be blown out evenly to each room.

〔Effect of the invention〕

As explained above, the present invention relates to a refrigerator in which chilled cold air is blown to a cold air damper in a refrigerator compartment using an internal circulation blower, an ice-temperature chilled compartment formed in the lower part of the refrigerator compartment, Since the compartment and vegetable compartment are made of resin containers and a glass plate is interposed between the containers, special cold air ducts, cold air volume adjustment dampers, and partition plates are required to create multiple temperature zones within the refrigerator compartment. Because I don't need it,
This is a cost-effective refrigerator. In addition, two or more cold air guide ducts are provided facing the cold air discharge damper to be used exclusively for each room, and the temperature of each room is controlled by changing the ventilation resistance of the ducts. Because of this, it is possible to easily create a temperature difference between the ice-temperature chilled chamber 4 and the refrigerated chilled chamber 5, and there is no need to use any special parts.

Furthermore, the location where it is easiest to secure the amount of cold air is located in the ice-temperature chilled room (−
1°C), which simplifies cooling control, and by forming the lower end of the cold air duct into a fan shape, each room can be cooled to a uniform temperature.

Furthermore, by interposing a glass plate between each container, not only can the temperature range between each room be maintained, but also the containers can be pulled out without being affected by condensation caused by temperature differences. .

That is, since moisture condenses on the glass plate and does not adhere to the bottom of the container, there is no need for the moisture to drip onto the floor or the like when the container is pulled out.
