Description

  The present invention relates to a heat insulating housing that forms a main body case such as a vending machine or a freezing / refrigerating showcase.

  Conventionally, in vending machines and refrigerated / refrigerated showcases, a plate-like heat insulating material formed of urethane foam resin or the like has been used in order to ensure high heat insulation of a main body case for storing products. In recent years, there has been a strong demand for energy saving of equipment from the viewpoint of environmental problems, and high-efficiency electrical components, energy-saving control, and heat insulation performance have been improved, and attention has been paid to reducing power consumption. In addition, it is necessary to appeal that the safety standards for the products of the customers who purchase the products are high, and it is safe not only for the content products but also for the product containers.

In a heat insulating housing formed by incorporating a plurality of plate-like heat insulating materials into a rectangular shape, there is a case where a sealing function is formed by interposing a liquid or gel-like material at a site where each plate-like heat insulating material abuts. . (For example, see Patent Document 1)
The conventional heat insulation casing described in Patent Document 1 first forms a rectangular outer box constituting the outer surface of the main body case, and then arranges the heat insulation casing inside the outer casing. As an example of the arrangement of the heat insulation housing, first, a heat-insulating upper plate is arranged on the upper lower surface of the outer box, and then a heat-insulating bottom plate is arranged on the bottom surface of the outer box, and further, heat insulation is performed on both sides of the outer box. In addition, a heat-insulating side plate is disposed, and a heat-insulating back plate is disposed on the back side of the outer box, thereby forming a rectangular heat-insulating housing inside the outer box. Thereafter, liquid or gel-like materials having adhesiveness and sealing properties are incorporated in each plate-like heat insulating material in contact with each other.

  However, in the conventional configuration, in a vending machine or a showcase having a plurality of product storage rooms, a bad odor is generated due to a substance that volatilizes from a liquid or gel material in the product storage room. Furthermore, the product had a problem that off-flavors were transferred.

  The present invention solves the above-described conventional invention, ensuring high sealing performance and fixing each plate-shaped heat insulating material without using a liquid or gel material, and a heat insulating casing with high heat insulating efficiency. The purpose is to provide.

  In order to solve the above-described conventional problems, the heat insulating casing of the present invention is incorporated in a portion where the plate-like heat insulating materials come into contact with each other via a fixing member having a sealing function and a removal preventing function.

  Thereby, it is possible to prevent the transfer of a strange odor to the product while ensuring the sealing performance of the heat insulating housing.

The heat insulating housing of the present invention secures high sealing properties and fixes each plate-like heat insulating material,
Migration of off-flavors to products can be prevented.

(Embodiment 2)
FIG. 6 is a plan cross-sectional view of the heat insulating casing in the second embodiment of the present invention. FIG. 7 is a plan cross-sectional view of the main part of the heat insulating casing in the second embodiment. FIG. 8 is a main part plan cross-sectional view showing a state after the side plate heat insulating material of the heat insulating casing in the second embodiment is incorporated.

  Hereinafter, Embodiment 2 of the heat insulation housing | casing by this invention is demonstrated, referring drawings. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the figure, the planar material 8 having a sealing property and a sliding property is interposed at the time of assembling at a portion where the heat insulating housing 3 abuts each other. In FIG. 7, the planar material 8 having a sealing property and a sliding property has a structure in which release papers 10 and 11 are bonded to both surfaces of a soft heat insulating material 9 with an adhesive.

  The release paper 10 on one side of the sheet material 8 having sealing properties and sliding properties is peeled off and attached to the end portion of the side plate heat insulating material 35. Since the release paper 11 on the opposite side is not peeled off, the surface is covered with a release paper having good slipperiness.

  In general, the soft heat insulating material 9 is a foamed foam molded article, and has a low surface slipperiness. If the sliding property is low, the assembling workability when incorporating the side plate heat insulating material 35 is deteriorated and the production efficiency is lowered.

  The soft heat insulating material 9 attached to the side plate heat insulating material 35 is compressed (E dimension compression) by the back plate heat insulating material 31 to ensure a sealing property. However, when assembled in a compressed state, it becomes difficult to incorporate due to the mutual repulsive force. In particular, if the compressed surface has poor sliding properties, it becomes more difficult to incorporate. Therefore, in order to improve the slipperiness of the compressed surface, the compression side is incorporated without peeling off the release paper 11.

  About the heat insulation housing | casing comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The heat insulating housing 3 incorporated in this way is closed by a heat insulating door 7 that can be freely opened and closed, and is provided with a cooling device (not shown) and a heating device (not shown) provided therein, Control is performed to cool or warm to a predetermined temperature, and the product can be stored at the predetermined temperature. A paper system provided on each plate-like heat insulating material or each surface of the plate-like heat insulating material by incorporating a sheet-like material 8 having a sealing property and a sliding property into a portion where each plate-like heat insulating material comes into contact with each other. It is possible to make contact with the surface material or the resin-based surface material, to secure a high sealing property at the abutting portion and to suppress heat loss. Further, in the present embodiment, since a volatile adhesive or sealer is not used, it is possible to prevent a strange odor generated during volatilization.

  As described above, in the present embodiment, by incorporating the planar material 8 having a sealing property and a sliding property into a portion where the respective plate-like heat insulating materials are in contact with each other, high sealing performance of the contacting portion is achieved. As a result, heat loss can be suppressed, and at the same time, the transfer of off-flavors to products can be prevented and materials can be rationalized.

  The heat-insulating housing of the present invention is provided with all the heat-insulating housings for storing food because it can secure high sealing performance and can fix each plate-like heat insulating material to prevent a strange odor from being transferred to products. It can also be applied to vending machines, refrigerators / refrigerators, and refrigerator / freezer showcases.
