FIG. 5 is an enlarged view of the front end portion of the heat insulating partition plate 10 composed of the vacuum heat insulating member 14 and the heat insulating protective member 16, and FIGS. 5 (a), 5 (b), and 5 (c). Shows different forms.

  As shown to Fig.5 (a), the packing 20 is attached to the front-end part of the heat insulation partition plate 10, and comes to improve the sealing property in the front-end part of the heat insulation partition wall 10 when the inner door 5 closes. ing.

  The packing 20 includes a base portion 20a attached to the front end portion of the heat insulating partition wall 10 and a 20b bulging from the base portion 20a. In the case shown in FIG. 5A, a metal frame 22 is attached to the front end portion of the heat insulating partition wall 10, and an engaging portion is provided on the base portion 20 a of the packing 20. The metal frame 22 is provided with a protruding portion that protrudes in a hook shape from the front end thereof, and an engaging portion provided on the base portion 20a is engaged therewith.

  The metal frame 22 is attached to the heat insulation partition wall 10 with a fixing tape 29. Specifically, as shown in FIG. 5A, the metal frame 22 has a cross-sectional shape in contact with the front end portion of the heat insulation protection member 16. A letter-shaped auxiliary metal fitting 24 is arranged in a state of sandwiching the vacuum heat insulating member 14 from the left and right, and the fixing tape 29 is stuck across the metal frame 22 and the heat insulating protective member 16.

The tape 29 may be attached.

  The heat insulating partition walls 10 configured as described above form a plurality of heat insulating chambers 12 by being arranged in the width direction inside the heat insulating cabinet 4 as shown in FIG. At this time, since each heat insulating chamber 12 is covered with a vacuum heat insulating member 14 made of a single face material, the number of products stored in the heat insulating chamber 12 increases, and the vending machine main body as shown in FIG. Even if the back surface of 2 is swelled, the back surface and both side surfaces of the heat insulating partition wall 10 are connected as a single plate, so there is no gap between the back surface and both side surfaces, and the heat insulating performance is reduced. Can be minimized.

Moreover, according to this embodiment, the following problems are solved.
When the heat insulating partition wall 10 is composed of only the vacuum heat insulating member 14, the heat insulating chamber is damaged when the vacuum heat insulating member 14 is damaged during the operation of storing the product 7, or when the entire vending machine 1 is shaken by an external impact. There is a possibility that a device (such as the product storage device 8) disposed in the 12 may damage the vacuum heat insulating member 14. At this time, if the vacuum state inside the vacuum heat insulating member 14 is damaged due to the scratches attached, the heat insulating performance is significantly lowered.

In a state where the thin wall portion is bent, the inclined surfaces 19d of the thick wall portions 19a, 19b, and 19c are in contact with each other as shown in FIG.

  By configuring the vacuum heat insulating member 19 in this way, the vacuum heat insulating member 19 is inclined at the corners of the boundary between the side surface portions (thick portions 19b and 19c) and the back portion (thick portions 19a). Since 19d is in contact with each other, both side portions and the back portion can be brought into close contact with each other, and the heat insulating performance of the corner portion can be improved.

  In addition, although not shown in the drawing, in some of the heat insulating chambers, the heat may move somewhat (for example, two heat insulating chambers for HOT products having the same temperature are arranged side by side, In the case where a heat insulation chamber for COLD products is arranged), the heat insulation by the vacuum heat insulation member 14 and the heat insulation protection member 16 is provided only in the heat insulation chamber (in the above-mentioned example, the heat insulation chamber for COLD products) whose heat insulation performance is desired to be improved. The partition wall 10 may be provided, and the other heat insulation chamber may be provided with a heat insulation partition wall made of only the heat protection member 16.

It is also possible to form the vacuum heat insulating member 14 by forming a bent corner portion 14i with thick wall portions at both ends and contacting the left and right side vacuum heat insulating members 14g and 14h with the bent corner portion 14i. In this way, it is possible to form a heat insulating partition wall suitable for vending machines of various dimensions, and to divide the vacuum heat insulating member into smaller ones, which can reduce manufacturing costs. it can.

  Moreover, as shown in FIG.3 (d), you may make it match | combine with the height of the vending machine 1 as a whole by arranging a plurality of the vacuum heat insulation members 14 vertically. In this way, it is possible to form a heat insulating partition wall suitable for vending machines of various heights, and to divide the vacuum heat insulating member 14 into smaller ones, thereby reducing manufacturing costs. be able to.
