Description

[Detailed description of the invention]

The present invention relates to a method for assembling a box for a so-called two-temperature refrigerated vehicle. Conventionally, in this type of refrigerator-freezer, especially in those in which the inner box is separate from the freezing chamber and the inside of the partition wall forms a cooling chamber for storing a cooler, the bottom wall of the inner box of the freezer N is cooled as described above. It serves as the bottom wall of the room. Therefore, in order to guide the dew water from the cooler for defrosting to the drainage hole provided at the back of the refrigerator, the bottom wall of the freezer compartment is usually sloped low towards the back, and the wholesale freezer compartment is usually The back is vertically wider than the front. In order to prevent deformation of the outer box of the inner partition wall part during the foaming of the insulation material in the manufacturing process, the inner partition reinforcing plate is fixed in advance by spot welding etc. to the opening of the outer box corresponding to the inner partition wall. However, in this case, if you try to insert the freezer compartment box from the front opening of the outer box, which is partitioned by the inner partition reinforcing plate C: Since the vertical dimension of the section is large, this maximum vertical dimension part hits the partition reinforcing plate and cannot be inserted. The present invention has been made in view of these drawbacks, and will be described in detail below with reference to the drawings. Figure 1 shows a cross-sectional view of the upper side of a so-called two-temperature refrigerator, and (l) shows the refrigeration unit with ml heat material in the space between the outer box (21), the freezer compartment box (31), and the refrigerator compartment box (41). (51 is filled with foam. (6) is a partition wall between the bottom wall (3a) of the freezer compartment box (31) and the refrigerator compartment box (31).
4), and the bottom wall (3a) of the freezer compartment box (31) and the bottom wall (3a) of the freezer compartment bottom plate 1.
1) Cooling formed between! [811'(Cooler (9)
). The air cooled by this cooler (9) is sent to the duct flυ by blower IIIaI and frozen! 121 and the refrigerator compartment (I3) are distributed and supplied. Also, 04 is the freezer compartment door, and the rotor is the refrigerator door. Now, the opening of the refrigeration unit (outer box f2 corresponding to the inner partition part (6)) Inside the edge, a partition reinforcing plate 18 is fixed at both ends with slots, etc., and this reinforcing plate 18 is refrigerated over the entire length of its upper and lower ends, as shown in the cross-sectional view of Fig. 44. A U-shaped flange (16A) is formed to engage the front flange (3b) of the M inner box (3) and the front 7 langes (4b) of the refrigerated 1 yen box (4).
In the embodiment, a high-temperature refrigerant pipe aη for preventing dew buildup on the front surface of the partition is fixed to the back surface of 8. Here, (16b) is a hole for attaching a middle hinge (not shown) for HA4 and AS. In this way, the reinforcing plate a is attached to the outer box (2).
By fixing e in advance, not only will there be no deviation in the dimensions of the partition part when the heat insulating material 153 is foamed, but also the high temperature refrigerant pipe on-? It is effective because it can be fixed in advance, the number of parts is reduced compared to fixing them during assembly, and there are no inconveniences such as misalignment. However, as shown in the first cross-sectional view, the freezer compartment box (31) has its bottom wall (5a) as the mounting surface for the cooler (9).Therefore, the bottom wall (3a) is used as the surface on which the cooler (9) is placed. Normal refrigerator +11
Therefore, the freezer compartment box (3) has its maximum vertical dimension (Hl) not at the mouth but at the back. Here, the outer 11+21 openings divided by the inner partition reinforcement plate (161) are respectively upper I!1D (21 and lower opening (2b)), and the respective vertical dimensions are (H), (H8) and T (El ) < (E (1 piece), and normally (Ht) < (Hi). Therefore, the freezer compartment box (31) is moved from the upper IMO (2 m) to the outer box (2).
Circle C: Even if you try to insert it, it cannot be inserted because its maximum vertical dimension gets stuck to the inner partition reinforcing plate (lG).Therefore, in the present invention, as shown by the arrow in Fig.

Lower opening (2b) with larger dimensions than [21]
Insert the outer box (2) into the circle, then hold it upward, 1-,
If the front flange [3b] of the freezer compartment box [31]
From the upper opening (2a) to the outside of the outer box (2)≦: Pull it out and then connect it again to the front U-shaped flange (20) of the outer box (2) and reinforce the partition! ! U-shaped 7 langes above t+e (16A)
The front flange (5b) is inserted into the circle in the same way as in the past and is engaged to fix the freezer compartment box (31) to the outer box (2). If a reinforcing plate is installed at the position corresponding to the C1 partition to prevent the box from deforming, the maximum vertical dimension at the back of the freezer compartment box will be replaced by the reinforcing plate (= the inconvenience of not being able to insert it into the outer box). It can be easily inserted and inserted in the same way as before.
4, which improves workability and has a great effect on mass production.
