Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator which is suitable for, for example, a so-called bottom freezer type in which a freezing compartment is arranged at the lowermost portion of a heat insulating box, and which has an improved assembly structure of peripheral components of a cooler.

[0002]

In a household refrigerator, a refrigerator having a freezer in the middle or upper tier has been more common than before, but in recent years, a refrigerator in the lower tier has been placed in the middle. So-called bottom-free-the-type, which has a vegetable compartment, is becoming available. In this case, in the refrigerator, the cooler and its peripheral components (fan device,
Cold air distribution mechanism consisting of cold air supply duct, damper device, etc.)
Is installed on the inner wall surface of the freezer (the inner surface of the inner box), but in the above bottom freezer type refrigerator, the machine room where the compressor etc. are installed on the lower back side of the main body is Since they are provided, it is necessary to shift their arrangement positions upward by that amount. For this reason, there has been a situation in which the cooler and its peripheral components must be provided at the height above and below the heat insulating partition wall that partitions the vegetable compartment and the freezer compartment from each other.

Therefore, in a conventional bottom freezer type refrigerator, for example, as disclosed in Japanese Patent Laid-Open No. 8-247638, a heat insulating partition wall for partitioning a vegetable compartment and a freezer compartment is divided into two parts, one of which is a front part. The first partition wall on the front side is attached in advance to the heat insulation box, and the space where the second partition wall is removed is used to assemble the cooler and its peripheral components. The second partition wall on the rear side is attached to form the entire heat insulating partition wall.

By the way, since the temperature zones of the vegetable compartment and the freezer compartment are largely different, there is a situation that a high sealing property is required between the peripheral edge of the heat insulating partition wall and the inner wall surface of the heat insulating box. However, the above-mentioned JP-A-8-24763
In the technique disclosed in Japanese Patent Publication No. 8, the first partition wall of the heat insulating partition walls is attached in advance during the foaming work of the foamed heat insulating material of the heat insulation box, so that the first partition wall side is formed by the foaming pressure. Although it is possible to obtain high adhesion and adhesion between the edge portion and the heat insulating box, the second partition wall is detachably attached after the foaming work of the foamed heat insulating material, so that the second partition wall and the second partition wall are attached. Adhesion between the heat-insulating box and the heat-insulating body is naturally reduced, and sufficient sealability cannot be obtained as it is. For example, there is a drawback that a separate sealing material is provided and tight sealing is required.

Further, in the above-mentioned conventional one, since the heat insulating partition wall is divided into two parts and a part of them is detachably attached, the structure becomes relatively complicated and the assembling property is not always good. In addition, at the time of servicing, the cooler and the cool air distribution mechanism cannot be inspected, parts replaced, etc. unless the second partition wall is once removed.
It was also inferior in serviceability.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a cooler and a cool air distribution mechanism at a height above and below a heat insulating partition wall. An object of the present invention is to provide a refrigerator capable of ensuring a high sealing property between the wall and the inner wall surface of the heat insulating box while improving the assemblability and serviceability.

However, the damper unit 24 is configured by being fitted from the back side, and in the damper unit 24, the flange portion 30a of the damper cover 30 is detachably engaged with the flange portion 23b of the evaporation cover 23 with respect to the above-mentioned evaporator cover 23. It is designed to be attached by. As a result,
As shown in FIG. 3, the damper cover 30 constitutes the back surface of the vegetable compartment 7, and
The upper part of the cool air supply duct 29 is formed between the heat insulator 31 and the heat insulator 31, and the upper end of the cold air supply duct 29 is connected to the lower end of the refrigerating compartment duct 21 (duct forming member 22). There is.

At this time, as shown in FIG. 1, a fitting recess 11c is formed at the rear end of the upper surface of the heat insulating partition wall 11, and the lower side portion 24 of the damper unit 24 is formed.

Furthermore, in the present embodiment, the height position of the upper end of the damper unit 24 is lower than the partition 9 (bottom plate 9b) by a predetermined dimension. It is configured. Thus, the damper unit 24 can be removed by an operation such as pivotally pulling it toward the front side in the vegetable compartment 7. It goes without saying that the damper unit 24 can be attached in the reverse order.

As will be described later in the description of the assembling process, in this embodiment, in order to assemble the cooler 19 and the cool air distribution mechanism 20 having the above-mentioned configuration to the refrigerator body 1 (insulating box body 2), In a state where the heat insulation partition plate 11 is attached to the heat insulation box body 2 in advance, for example, the freezer compartment 8 is installed in the assembly space portion 34 (see FIG. 6 and the like) formed between the heat insulation partition plate 11 and the inner box 3. The cooler 19 is assembled from the side, and then the evaporator cover 23 with the damper unit 24 is fitted from the refrigerating compartment 6 side through the vegetable compartment 7, and the freezer compartment front cover 25 is assembled from the freezing compartment 8 side. It is performed in the procedure of attaching.

At this time, the heat insulating partition plate 11 is formed when the foamed heat insulating material 5 constituting the heat insulating box 2 is formed (foaming work).
It is adapted to be attached (temporarily fixed) inside the inner box 3 in advance. Further, since the entire length (length dimension) in the height direction of the one in which the damper unit 24 is attached to the evaporation cover 23 is slightly longer than the height dimension of the vegetable compartment 7 (smaller than the height dimension of the refrigerating compartment 6), The assembling is performed in a state where at least the bottom plate 9b of the partition section 9 is not attached.

Next, the operation of the above configuration will be described. In assembling the refrigerator main body 1 having the above-described configuration, first, in the step of forming the heat insulating box body 2, the heat insulating partition wall 11 is attached in advance. Specifically, in order to manufacture the heat-insulating box body 2, the inner box 3 and the outer box 4 are assembled, and, for example, a urethane stock solution or the like is injected into the space formed between them, and foaming is performed while pressing the mold. By curing, the foamed heat insulating material (urethane foam) 5 is brought into a filled state. At the time of this foaming, the heat insulating partition wall 11 is previously provided inside the inner box 3.
Install.

Then, due to the foaming pressure of the foam insulation 5,
When the inner box 3 receives a force in the direction of expansion inside the chamber, both side edges of the heat insulating partition wall 11 and the inner side wall of the inner box 3 come into close contact with each other with a strong force, and a high sealing property therebetween is achieved. Therefore, it becomes unnecessary to provide a strict seal by post-processing with an expensive seal material. At this time, an assembling space 34 in which the cooler 19 and the cool air distribution mechanism 20 are assembled is secured between the rear side of the heat insulating partition wall 11 and the inner box 3.

Then, the step of assembling the cooler 19 and the members constituting the cool air distribution mechanism 20 into the assembly space 34 inside the inner box 3 of the heat insulating box 2 is as follows. Done. That is, first, the cooler 19 is assembled along the inner surface of the inner box 3. The assembling of the cooler 19 is performed from the freezing compartment 8 side below the heat insulation partition wall 11 or the vegetable compartment 7 side above depending on the size of the opening of the freezing compartment 8 and the vegetable compartment.

Next, the assembling of the cover 23 and the damper unit 24 is carried out.
The fan device 26 is attached to the fan attachment portion 27 of the ever cover 23, and the damper unit 32 and the heat insulator 31 having the rear heat insulating material 33 assembled therein are fitted into the damper cover 30 to form the damper unit 24. deep. Then, as shown in FIG. 6, those having the damper unit 24 attached to the everting cover 23 are fitted and assembled from the refrigerating compartment 6 and the vegetable compartment 7 side above the heat insulating partition wall 11.

At this time, the size in the height direction of the one in which the damper unit 24 is attached to the evaporation cover 23 becomes large, but if the partition 9 is not yet attached in the inner box 3, the work can be easily performed. You can Along with this, the freezer compartment front cover 25 is assembled from the freezer compartment 8 side. Thereafter, the duct forming member 22, the partition 9 and the like are assembled in the inner box 3. Thus, as shown in FIGS. 1 to 3, the cooler 19 and the cooler 1 thereof are located at a height above and below the heat insulation partition wall 11 on the inner wall surface side in the heat insulation box 2.
The cool air distribution mechanism 20 including the fan device 26, the cool air supply duct 29, the damper device 32, and the like for sending the cool air from the air conditioner 9 can be easily assembled.

As described above, according to the present embodiment, the cooler 19 and the cool air circulation mechanism 20 are provided at the height above and below the heat insulating partition wall 11, and the inner box 3 is previously provided with the cooler 19. Since it is possible to assemble the components of the cooler 19 and the cool air circulation mechanism 20 with the heat insulating partition wall 11 attached, it is not necessary to divide the heat insulating partition wall 11 into two parts or to retrofit the heat insulating partition wall 11, and the heat insulating partition wall 11 can be installed. It is now possible to perform the foaming work of the heat insulating box body 2 after assembling 11 in advance. Therefore, even if there is a large difference in temperature zones between the upper and lower chambers (vegetable chamber 7 and freezing chamber 8) of the heat insulating partition wall 11, it is not necessary to provide a separate sealing material later to perform a strict seal. Therefore, it is possible to secure a high sealing property between the heat insulating partition wall 11 and the inner wall surface of the heat insulating box body 2.

Then, the cold air circulation mechanism 20 is constituted by an evaporator cover 23 to which a fan device 26 is attached, and a damper unit 24 in which a damper device 32 is incorporated into a thermal insulator 31 to form a unit, and these are insulated. Partition wall 1
Since it can be fitted and attached from above 1, it is possible to greatly improve the assembling property. Especially in this embodiment,
Since the structure in which the damper unit 24 is attached to the evaporation cover 23 can be assembled at once, the assembling property can be made extremely excellent.

Further, the damper unit 24 and the air cover 23 can be easily removed without removing the heat insulating partition wall 11, and the work such as the inspection of the cooler 19 and the cool air distribution mechanism 20 and the replacement of parts can be facilitated. Serviceability can be improved. In this case, especially in this embodiment,
Since the damper unit 24 is configured to be attachable to and detachable from the vegetable compartment 7 without removing the partition portion 9, serviceability can be further improved.

In the above embodiment, the construction in which the damper unit 24 is attached to the evaporation cover 23 in the assembling space portion 34 is assembled at once, but in the other embodiment of the present invention shown in FIG. As described above, the evaporator cover 23 to which the fan device 26 is attached and the damper unit 24 may be separately assembled, and even with such a configuration, the assemblability can be sufficiently improved.

In addition, the present invention is not limited to the above-mentioned embodiment, and for example, a partition for partitioning the refrigerating compartment and the vegetable compartment may be located immediately above the damper unit. The unit configuration and the like can be modified in various ways without departing from the scope of the invention, such as various modifications.
