DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a casing of a vending machine for selling a product in a cooled or heated state in accordance with a customer's request.

[0002]

2. Description of the Related Art Conventionally, this type of vending machine has an outer shell constructed by incorporating an insulated door and a main door at the front of an insulated housing having a top surface, a bottom surface, both side surfaces, and a back surface, and a product inside. , A cooling device, a warming device, and the like. The conventional housing of such a vending machine protects the internal product from the external environment (the climate or atmosphere in which the vending machine is installed) and keeps the product warm and warm.
It has a function as a cool box. For this reason, the housing
An outer box comprising a top plate, a bottom plate, left and right side plates and a back plate, an inner box smaller than the outer box and formed in a substantially similar shape, and a heat insulating member disposed between the outer box and the inner box. The inner box and the outer box are assembled by welding steel plates to each other, and have sufficient strength. Further, the outer case has an airtightness necessary for protecting the internal devices and products from the weather, dust, and theft. Further, the heat insulating structure of the housing maintains heat insulating properties by disposing a thick plate-shaped heat insulating piece made of foamed polyurethane or foamed styrene in the gap between the outer box and the inner box.

FIG. 7 is a sectional view of a main part of a vending machine showing a conventional example, and FIG. 8 is a sectional view of a main part of a plane of a vending machine showing a conventional example. As shown in the figure, the housing 1 includes an outer box 16 including a top plate 16a, a bottom plate 16b, left and right side plates 16c, and a back plate 16d; an inner box 17 formed to be smaller than the outer box 16 and having a substantially similar shape; It is configured by disposing thick heat insulating pieces 18 to 22 made of urethane foam, styrene foam, or the like in a gap between the outer box 16 and the inner box 17. In addition, a heat insulating door 2 and a main door 3 are incorporated in the front of the housing 1 to form an outer shell, and a rack 4 for storing goods and a cooling device 5 are built therein.

[0004]

By the way, in the conventional case structure, the outer case, the inner case, and the heat insulating member can be easily separated from each other, which is one of the important requirements for recent product development. Products that take into account the effects of the above, that is, good from the viewpoint of recyclability. However, in the structure, a gap is provided in each part due to the necessity of easily assembling and disassembling. At the time of cooling the product, cool air leaks from this gap, lowering the heat retention performance inside the refrigerator, and moisture in the air condenses and adheres to the gap on the surface of the inner box, and the heat insulating material absorbs moisture and insulates it. There is a problem that the performance decreases with the passage of time. Therefore, in order to solve such a problem, in the past, putty or the like was filled in the gap such as the joint portion of the heat insulating piece to close the gap, but it took time and effort to work,
There was a problem that the putty served as an adhesive and the housing was not easily disassembled.

In view of the foregoing, the present invention has been made in view of the above-described problems, and has been made in consideration of the above circumstances. An object of the present invention is to provide a housing of a machine.

[0006]

According to a first aspect of the present invention, there is provided an outer box comprising a top plate, a bottom plate, both side plates, and a back plate, and disposed inside the outer box. Inner box, top, bottom, both sides, between the outer and inner boxes,
A heat insulating member disposed on the back, and a seal member for closing a gap between joints between the adjacent heat insulating members, wherein the seal member is sandwiched between the adjacent heat insulating members at the joint to form a gap between the joints. And a reinforcing portion for reinforcing the soft portion, and the soft portion and the reinforcing portion are formed integrally, so that the reinforcing portion maintains the shape of the seal member substantially constant. In addition, the present invention provides a vending machine housing in which the handling is simplified and the soft part is deformed in accordance with the gap of the joint part to reliably close the gap.

According to a second aspect of the present invention, in the first aspect of the present invention, a notch is formed in a joint side end surface of the heat insulating member, and a groove having a shape complementary to the shape of the soft portion is formed in the joint. By doing so, it is possible to improve the airtightness of the joining portion of the heat insulating member.
