Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a casing of a vending machine that sells a product according to a customer's request in a state where the product is frozen / refrigerated or heated.
[0002]
[Prior art]
Conventionally, this type of vending machine is a rack in which a heat insulation door and a main door are incorporated on the front surface of a heat insulation housing composed of a top surface, a bottom surface, both side surfaces, and a rear surface, and an outer shell is configured to store products inside. A cooling device, a heating device, and the like are incorporated. The conventional housing of such vending machines has protection from the external environment of the internal products and equipment (climate, atmosphere, etc. where the vending machines are installed), product anti-theft functions, It has a function as a warm and cold storage. For this reason, the housing includes an outer box composed of a top plate, a bottom plate, left and right side plates, and a back plate, an inner box that is smaller than the outer box and formed in a substantially similar shape, and between the outer box and the inner box. It is comprised with the heat insulation member arrange | positioned. Each of the outer box and the inner box is assembled by joining steel plates by welding so that sufficient strength can be maintained. In addition, the outer box retains the airtightness necessary for protecting internal devices and goods from wind and rain, dust and theft. In addition, the heat insulation structure of the housing is designed so that after the inner box is assembled in the outer box, a foam material such as polyurethane is injected into the gap between the two boxes and foamed so that no gap is formed between the two boxes. That retains heat insulation (conventional example 1) and those that maintain heat insulation by disposing a thick plate-like heat insulating piece made of foamed polyurethane or polystyrene in the gap between the outer box and the inner box (conventional example) 2). More specifically, the conventional example 1 is a vending machine that sells frozen products and ice creams that require high heat insulation performance in the case where the product is stored because the storage temperature of the product greatly affects the storage quality. Conventional example 2 is used in a vending machine that sells beverages such as cans whose storage quality is not easily affected by storage temperature after cooling and heating.
[0003]
FIG. 7 is a sectional side view of the main part of the vending machine showing the conventional example 2, and FIG. As shown in the figure, the housing 1 includes a top plate 16a, a bottom plate 16b, left and right side plates 16c, a back plate 16d, an outer box 16, an inner box 51 that is smaller than the outer box 16 and formed in a substantially similar shape, In the gap between the outer box 16 and the inner box 51, plate-shaped heat insulating pieces 52, 53, 54, 55 made of urethane foam, polystyrene, or the like are arranged. And the heat insulation door 2 and the main door 3 are integrated in the front of the housing | casing 1, and an outer shell is comprised, The rack 4 and the cooling device 5 which store goods in the inside are incorporated.
[0004]
[Problems to be solved by the invention]
By the way, in the case structure in which the foam material is injected between the outer box and the inner box of Conventional Example 1 and foamed, the outer box, the inner box, and the heat insulating portion are integrally formed, which is relatively good. While maintaining heat insulation performance, it has the advantage of increasing the strength of the chassis, but disassembling work such as separating the outer box from the inner box is extremely difficult and will become a requirement for future product development.
