The present invention relates to a method for forming a heat insulating box that prevents foaming in that area.

されている。 The details of the present invention will be explained below with reference to an embodiment shown in the drawings. 1 is a refrigerator main body, 2 is an outer box, 3 is an inner box, and 4 is a refrigerator body.
Reference numerals 5 and 6 indicate a foam heat insulating material, 5 and 6 indicate doors, and 7 indicate a partition wall. 8 indicates a freezer compartment, and 9 indicates a refrigerator compartment. A cooler 11 provided near the back wall of the freezer compartment 8 is a blower that forcibly circulates cold air cooled by the cooler to the freezer compartment 8 and the refrigerator compartment 9. 12
13 is a condenser, and 13 is located above the bottom insulation wall 4a formed by the outer box 2 and inner box 3, and directly below is the deep part 3a of the inner box 3.
This is an injection port provided on the back plate portion 2d of the outer box 2 where the is located. When injecting the stock solution of foam insulation material from this injection port, as shown in Fig. 2,
After applying the outside box 15 to the inner box and outer box, tilt the injection nozzle 16 at an angle of Q2 (for example, 30 degrees) with respect to the injection port 13 so that the stock solution spouted from the nozzle 16 smoothly flows toward the opening of the refrigerator as shown by the arrow. It is structured to flow.
尚この時原液の流れを良くする為に内箱３の奥
部３ａにはＱ１（30゜〜60゜の間）の傾斜面３
a′が設けられている。 At this time, in order to improve the flow of the stock solution, there is an inclined surface 3 of Q1 (between 30° and 60°) at the back 3a of the inner box 3.
a′ is provided.

である。 Accordingly, the stock solution ejected as indicated by arrow P2 is also guided to the inclined surface 3a' and reaches the lowest part of the opening. With this configuration, the ejected stock solution does not adhere to the area around the injection port, start foaming around the injection port, and block the area near the injection port. Even if the stock solution adhering to the vicinity of the injection port were to foam, it would not interfere with the formation of the heat insulating material foaming from the injection port.
更に、内箱の奥部に付着した原液が発泡して注
入口から箱体外に漏出し、冷蔵庫の外観を損ねる
という欠点が解消される。 Furthermore, the drawback that the stock solution adhering to the deep part of the inner box foams and leaks out of the box from the injection port, spoiling the appearance of the refrigerator, is eliminated.

ことがないものである。 As explained above, the present invention provides a space created by the outer box and the inner box from the injection port provided at the corner of the inner box on the back side of the space created by the outer box and the inner box and directly below. In the heat insulating box body in which the foam heat insulating material is filled in the inner box, the injection nozzle for injecting and foaming the foam heat insulating material is tilted at an angle of Q2 with respect to the injection port, and an inclined surface of Q1 is also provided at the back of the inner box. This prevents the undiluted solution spouted from the injection port from adhering to the area around the injection port and interfering with the formation of the foamed heat insulating agent.
