Japanese Unexamined Patent Publication No. 8-54173

However, a foaming agent is generally used as a heat insulating material, and when a hole is made in the foaming agent, the inner wall of the hole is exposed to the outside, so that the foaming agent easily absorbs water and when the wiring is passed through the hole. The wiring gets caught in the foaming agent and becomes difficult to pass through. In addition, since it is necessary to make a hole with a drill after forming a heat insulating material by filling with a foaming agent, the work of assembling the cooling storage becomes complicated.

The present invention has been completed based on the above circumstances, and an object of the present invention is to abolish the work of drilling holes in the heat insulating material and to prevent water absorption by the heat insulating material.

The present invention has an outer box and an inner box arranged inside the outer box, and has a heat insulating box body in which a filling space is formed between the outer box and the inner box, and a first wiring. A first electrical component mounted on the heat insulating box body and a wiring insertion member having a wiring space isolated from the filling space are provided, and the wiring insertion member is mounted on the heat insulating box body. A cooling storage in which the filling space is filled with a heat insulating material, and the wiring insertion member is opened upward with a first wiring portion through which the first wiring is inserted in the vertical direction in a state of being in contact with the inner box. A second wiring portion having an upper surface opening and extending to the front end of the filling space in a state where the opening edge of the upper surface opening is in contact with the outer box, and the first wiring is inserted in the front-rear direction. The outer box is provided with a hole drilling portion provided so as to coincide with the upper surface opening of the wiring insertion member.

According to such a configuration, the wiring insertion member is attached to the heat insulating box body, and the first wiring is pulled out from the first wiring portion above the second wiring portion. At this time, since the second wiring portion has an upper surface opening and the outer box has a hole drilling portion, the first wiring can be pulled out above the outer box, and the wiring work becomes easy. Next, the first wiring once pulled upward from the upper surface opening is bent toward the upper surface opening side and pulled out forward from the front end of the filling space. Further, since the wiring space of the wiring insertion member is isolated from the filling space of the heat insulating box, the wiring space is not filled with the heat insulating material even if the filling space is filled with the heat insulating material. That is, the work of drilling a hole in the heat insulating material after forming the heat insulating material becomes unnecessary, and the work of assembling the cooling storage becomes easy. Further, even when a foaming agent or the like that easily absorbs water is used as the heat insulating material, the heat insulating material is covered with the outer box and the inner box and is not exposed to the outside, so that the water absorption by the heat insulating material can be prevented.

Further, a joiner that connects the opening of the outer box opened forward and the opening of the inner box opened forward to close the filling space, and below the joiner in the opening of the heat insulating box body. The first electrical component includes a second electrical component having a second wiring and mounted inside the center frame, and the wiring insertion member is inside the center frame. A third wiring unit for drawing out the second wiring from the second wiring unit may be further provided.
According to such a configuration, the second wiring can be pulled out from the third wiring portion above the second wiring portion and then bent toward the upper opening side so as to be pulled out to the front of the outer box.

Further, the outer box has a front wall that covers the filling space from the front, an upper wall that covers the filling space from above, and a mounting wall fixed to the front wall. The second wiring portion provided on the upper wall has a front locking piece that locks to the mounting wall from the front and a rear locking piece that locks to the mounting wall from the rear. It may be configured as such.
According to such a configuration, since the second wiring portion of the wiring insertion member is exposed above the outer box through the drilling portion, the wiring work of the first wiring is performed after the wiring insertion member is mounted on the upper wall of the outer box. be able to. Further, since the front locking piece is locked to the mounting wall from the front and the rear locking piece is locked to the mounting wall from the rear, the wiring insertion member can be positioned in the front-rear direction with respect to the mounting wall of the outer box.

The first wiring portion includes a first insertion protrusion that is inserted from above into a first through hole provided through the inner box, and the first insertion protrusion that penetrates the inner box. It may be configured to have a first flange portion that comes into contact with the opening edge portion of the first through hole while being inserted into the inner box.
According to such a configuration, the first insertion protrusion is inserted into the first through hole from above, and the first flange portion is brought into contact with the opening edge portion of the first through hole, so that the first wiring portion is brought into contact with the inner box. Can be positioned vertically.

The third wiring portion includes a third insertion protrusion that is inserted from above into a third through hole provided through the joiner, and the third insertion protrusion that penetrates the joiner and the center. It may be configured to have a third flange portion that comes into contact with the opening edge portion of the third through hole while being inserted inside the frame.
According to such a configuration, the third insertion protrusion is inserted into the third through hole from above, and the third flange portion is brought into contact with the opening edge of the third through hole to bring the third wiring portion to the joiner. Can be positioned vertically.

According to the present invention, the work of drilling holes in the heat insulating material can be abolished, and the absorption of water by the heat insulating material can be prevented.
