Description

本発明は、冷蔵庫およびその製造方法に関し、特に、運搬のための把手が断熱箱体後面に配設される冷蔵庫およびその製造方法に関する。 The present invention relates to a refrigerator and a method for manufacturing the same, and more particularly to a refrigerator in which a handle for transportation is arranged on the rear surface of a heat insulating box and a method for manufacturing the same.

一般的な冷蔵庫は複数の貯蔵室を有し、例えば、上方から、冷蔵室、冷凍室および野菜室を有している。また、これらの貯蔵室は断熱箱体の内部に形成されている。 A general refrigerator has a plurality of storage chambers, for example, from above, a refrigerator compartment, a freezer compartment, and a vegetable compartment. Further, these storage chambers are formed inside the heat insulating box body.

断熱箱体は、鋼板から構成される外箱と、外箱の内部に形成されて各貯蔵室を形成する樹脂板から成る内箱と、外箱と内箱との間に発泡充填される発泡充填剤とから構成される。このような断熱箱体から構成される冷蔵庫は重たいため、断熱箱体の後面などには、冷蔵庫を運搬するための把手が配設されている。冷蔵庫に把手が形成される構造は、例えば特許文献1に記載されている。 The heat insulating box is an outer box made of steel plate, an inner box made of a resin plate formed inside the outer box to form each storage chamber, and foam filled between the outer box and the inner box. Consists of filler. Since a refrigerator composed of such a heat insulating box is heavy, a handle for transporting the refrigerator is provided on the rear surface of the heat insulating box or the like. The structure in which the handle is formed in the refrigerator is described in, for example, Patent Document 1.

図12に、把手が形成された冷蔵庫100の一例を示す。図12(A)は冷蔵庫100の後方上端部を示す斜視図であり、図12(B)は当該部分の断面図である。 FIG. 12 shows an example of the refrigerator 100 in which the handle is formed. 12 (A) is a perspective view showing a rear upper end portion of the refrigerator 100, and FIG. 12 (B) is a cross-sectional view of the portion.

図12(A)を参照して、冷蔵庫100の後方上端部には運搬把手部105が嵌め込まれている。運搬把手部105は、冷蔵庫100の後方上端部をカバーする樹脂成形品であり、冷蔵庫100を運搬する作業者が手を掛けるための凹状部が形成されている。運搬把手部105は、ビス104を介して冷蔵庫100の断熱箱体101に取り付けられている。 With reference to FIG. 12A, a transport handle portion 105 is fitted in the rear upper end portion of the refrigerator 100. The transport handle portion 105 is a resin molded product that covers the rear upper end portion of the refrigerator 100, and has a concave portion for a worker who transports the refrigerator 100 to handle. The transport handle portion 105 is attached to the heat insulating box body 101 of the refrigerator 100 via the screw 104.

図12(B)を参照して、運搬把手部105の上端部を断熱箱体101に固定するビス104は、断熱箱体101の上面を内側に向かって貫通している。また、運搬把手部105の下端部は、断熱箱体101の後面に、外側から当接している。 With reference to FIG. 12B, the screw 104 for fixing the upper end portion of the transport handle portion 105 to the heat insulating box body 101 penetrates the upper surface of the heat insulating box body 101 inward. Further, the lower end portion of the transport handle portion 105 is in contact with the rear surface of the heat insulating box body 101 from the outside.

特開2001-66044号公報Japanese Unexamined Patent Publication No. 2001-66044

しかしながら、上記した運搬把手部105の取付構造は、構造的な観点からも外観意匠の観点からも改善の余地があった。 However, the mounting structure of the transport handle portion 105 described above has room for improvement from the viewpoint of structural viewpoint and appearance design.

具体的には、運搬把手部105の上端部を固定するビス104は、断熱箱体101に上面から挿入されている。即ち、ビス104は、断熱箱体101の上面を構成する外箱102およびその近傍の発泡樹脂103を貫通している。一方、発泡樹脂103の内部には、冷凍サイクルの冷媒が流通する冷媒配管が蛇行形成されている。よって、ビス104が冷媒配管に緩衝してしまう恐れがあった。 Specifically, the screw 104 for fixing the upper end portion of the transport handle portion 105 is inserted into the heat insulating box body 101 from the upper surface. That is, the screw 104 penetrates the outer box 102 constituting the upper surface of the heat insulating box 101 and the foamed resin 103 in the vicinity thereof. On the other hand, inside the foamed resin 103, a refrigerant pipe through which the refrigerant of the refrigerating cycle flows is meanderingly formed. Therefore, there is a risk that the screw 104 will buffer the refrigerant pipe.

更に、運搬把手部105の下端は、外箱102の背面に外側から当接している。運搬把手部105の下端の断熱箱体101に対する接着が十分でない場合、運搬時等に於いて運搬把手部105の下端が、外箱102の背面から剥がれてしまう恐れがあった。 Further, the lower end of the transport handle portion 105 is in contact with the back surface of the outer box 102 from the outside. If the lower end of the transport handle 105 is not sufficiently adhered to the heat insulating box 101, the lower end of the transport handle 105 may be peeled off from the back surface of the outer box 102 during transportation or the like.

更に、運搬把手部105が断熱箱体101を外側から被覆することから、略直方体形状を呈する断熱箱体101の上端後方部から、運搬把手部105が突出してしまい、冷蔵庫100全体としての外観意匠性が低下してしまう恐れがあった。 Further, since the transport handle portion 105 covers the heat insulating box body 101 from the outside, the transport handle portion 105 protrudes from the upper end rear portion of the heat insulating box body 101 having a substantially rectangular parallelepiped shape, and the appearance design of the refrigerator 100 as a whole. There was a risk that the sex would deteriorate.
