It is possible to suppress a decrease in strength due to.

  According to a fifth aspect of the present invention, in the invention of the third or fourth aspect, the opening of the inner box is blocked from the foam insulation filling side by the holding member, thereby preventing leakage of the foam insulation. it can.

  The invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein the storage room is a refrigeration room, and the built-in cooler and cooling elements of the blower fan face each other as they are. Can be used for indoor cooling.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a main part of a refrigerator compartment of a refrigerator according to Embodiment 1 of the present invention. FIG. 2 is a perspective view of the cooler engaged and held by the holding member in the same embodiment. FIG. 3 is a perspective view from the back of the inner box in the same embodiment.

  The refrigerating room 11 shown in FIG. 1 includes an outer box 12, an inner box 13, a heat insulating box 15 formed from a foam heat insulating material 14, and an open / close refrigerating room door 16 that closes the front opening of the refrigerating room. It is composed of A cooler 17 is provided on the back surface of the refrigerator compartment 11, and a blower fan 18 is provided on the upper portion thereof. The cooler is composed of a pipe 21 and a substantially flat metal plate 22, and is engaged and held by a resin-made holding member 23. The holding member closes the opening 24 of the inner box from the side filled with the foam heat insulating material. .

  FIG. 2 shows an assembly of the cooler 17 and the holding member 23 incorporated in the refrigerator main body, and the cooler 17 is fixedly held by an engaging portion 25 provided on the resin-made holding member 23. The size of this cooler is A for the width dimension and B for the height dimension. The holding member has a width dimension C and a height dimension D.

  As shown in FIG. 3, the opening 24 of the inner box 13 is provided on the back of the refrigerator compartment, and the size is E for the width dimension and F for the height dimension. Regarding the size relationship between the cooler 17, the holding member 23, and the opening 24 of the inner box 13, the width dimension increases in the order of the cooler, the opening, and the holding member, and A <E <C. The height dimension increases in the order of the opening, the holding member, and the cooler, and F <D <B.

  About the refrigerator comprised as mentioned above, the operation | movement is demonstrated below.

  First, the cooler 17 composed of the pipe 21 and the substantially flat metal plate 22 is fixed to the engaging portion 25 of the resin holding member 23 to form an assembly, and the heat insulating box body 15 is filled with the foam heat insulating material 14. It inserts and attaches from the side by which the foaming heat insulating material 14 of the opening part 24 opened to the back of the inner box 13 before is filled. At this time, since the width dimension A of the cooler 17 is smaller than the width dimension E of the opening 24 of the inner box, the cooler 17 can be inserted in the direction opposite to the engagement side with the holding member 23 of the cooler 17. Further, since the width C and height D of the holding member 23 are larger than the width E and height F of the opening 24, the opening can be covered and sealed with the holding member after the cooler is inserted.

  Next, the heat insulating box body 15 is formed by filling the foam heat insulating material 14, and the blower fan 18 and the decorative board 19 are assembled from the front opening of the refrigerator compartment 11 to constitute the air passage 20. Cold air can be sent to the cooler 17 by the blower fan 18 in the air passage 20 and directly heat-exchanged to be discharged into the refrigerator compartment 11.

  As described above, the refrigerator of the present embodiment can easily assemble the cooler 17 at a predetermined position inside the refrigerator. Further, the opening 24 of the inner box 13 can be made smaller than the height of the cooler 17 so that the strength of the inner box 13 can be ensured and the periphery of the holding member 23 can be sealed to prevent leakage when the foam insulation 14 is filled. Can be prevented.

  Further, the cooling fan can be efficiently cooled by contacting and circulating the cool air directly to the cooler.

  As described above, the refrigerator according to the present invention can be efficiently cooled by arranging a cooling element such as a cooler as it is in a facing room, and assembling is also easily performed while sealing the leakage of the foam insulation. It can be applied to foods, medicines, and other storage devices that have temperature control.
