[0005] In a preferred aspect of the present invention, the heat insulating partition plate has a guide member attached to one side of the urethane foam board, and an airtight packing attached to the guide member. One side of the urethane foam board constituting the heat insulating partition plate faces the inner door of the vending machine that closes the product storage, so that an airtight packing is attached to the one side. Since pressure is applied to the one side of the urethane foam board from the inner door through an airtight packing, in order to prevent local deformation near the one side of the urethane foam board, the one side of the urethane foam board is airtight. It is desirable to insert a guide member between the seal and the packing.

In a preferred embodiment of the present invention, the urethane foam board is covered with a water-impermeable film. Condensation forms on the heat-insulating partition plate and, consequently, on the surface of the urethane foam board facing the cooling chamber. The urethane foam board is desirably coated with a water-impermeable film in order to prevent the dew condensation water from penetrating into the urethane foam board and lowering the heat insulating performance of the heat insulating partition plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described. FIG.
As shown in FIG. 1, the vending machine 10 includes a main body 11 and an outer door 12. The main body 11 is partitioned into an upper product storage 13 and a lower machine room 14. An inner door 15 for closing the product storage 13 is provided. A plurality of product storage columns 16 are arranged in the product storage 13. A gap 17 for heat insulating partition plate insertion is formed between the product storage columns 16 adjacent to each other. By inserting the heat insulating partition plate 18 into the desired gap 17 for inserting a heat insulating partition plate, the product storage 13 is partitioned into a cooling room A and a heating room B. Cooling room A
A product to be sold after being cooled is stored in the product storage column 16 in the inside, and a product to be sold by heating is stored in the product storage column 16 in the heating chamber B. As shown in FIG. 3, the heat insulating partition plate 18 includes a urethane foam board 19, a metal or plastic guide member 20 that is externally fitted and fixed to one side of the urethane foam board 19, and adheres to the guide member 20. And a fixed airtight packing 21. The lower end of one side of the urethane foam board 19 is cut out, and the deformation preventing member 22 is adhesively fixed to the cutout. The urethane foam board 19 is covered with a water-impermeable film (not shown) such as a plastic film or an aluminum film. When the heat insulating partition plate 18 is inserted into the heat insulating partition plate insertion gap 17 and the inner door 15 is closed, the airtight packing 21 abuts on the inner door 15, and the cool air in the cooling chamber A and the warm air in the heating chamber B are separated.
