It is formed so as to be hermetically sealed at the opening of the magnet, and the magnet-containing packing 10 is attached to the lower portion inside. When the door 9 is closed, the packing receiver 6 is attracted by the magnetic force of the magnet-containing packing 10 to form an airtight structure inside the main body 1 of the storage, and the heater 7 generates heat to prevent dew condensation.

[0006]

[Problems to be Solved by the Invention]

 However, in the coupling device described with reference to FIG. 3, since the thickness of the main body portion 5c of the coupling portion 5 is large, the heat conduction between the heater 7 and the packing receiver 6 is poor, and the heating efficiency of the heater 7 is poor. is there.

That is, since the connecting portion 5 is made of vinyl chloride resin or the like and has poor heat conduction, and the main body portion 5c has a large wall thickness of about 2 mm, it is possible to receive packing from the heater 7 through the main body portion 5c. Heat conduction to 6 is poor, and a large heater capacity is required to prevent dew condensation. Further, in the configuration of FIG. 3, the heater 7 is fixed by the aluminum tape 8, the assembling work efficiency is poor, and the stainless steel is used for the packing receiver 6, which is a material cost increase.

By the way, Japanese Utility Model Publication No. 47-7191 discloses a connecting device having an iron plate arranged in a cross section of a breaker, and Japanese Utility Model Publication No. 46-13354 and Japanese Utility Model Publication No. 46-13355 disclose. Has its peripheral edge bent inwardly so that a predetermined thickness is formed at the opening edge of the outer box, and a peripheral end has a U-shaped cross-section. A connecting device is disclosed in which the peripheral end portion of the inner box is fitted and connected to the connecting portion. However, none of these communication devices is provided with a heater for preventing dew condensation.

Therefore, an object of the present invention is to provide a storage container coupling device having a heater with high thermal efficiency for preventing dew condensation.

[0010]

[Means for Solving the Problems]

 The present invention is a door having a main body of a storage having an opening formed by filling a space formed by an inner box and an outer box with a heat insulating material, and a packing containing a magnet arranged in the opening to make the main body an airtight structure. In a storage container connecting device having a connecting portion for connecting a peripheral edge portion of an inner box and a peripheral edge portion of an outer box, which is provided in a storage container, which is connected to an iron plate embedded in the connecting portion and attracted to a magnet-containing packing, An insertion groove formed on the back surface of the part and a heater for preventing dew condensation inserted in the insertion groove are provided.

[0011]

[Action]

 With the above configuration, the connecting portion is reinforced by the iron plate embedded in the connecting portion to be formed thin, and the heat from the heater is radiated through the iron plate having good heat conduction. Therefore, since the heat conduction of the connecting portion is improved, dew condensation can be efficiently prevented with a small heater capacity. In addition, the heater assembling work can be made more efficient, and the cost of the suction member can be reduced.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a vertical cross-sectional view of an essential part of a storage connecting device according to an embodiment of the present invention. The main body 1 of the storage is configured by filling a space formed by an inner box 2 and an outer box 3 with a heat insulating material 4, and the whole is a box body having an opened front surface. The outer box 3 has a peripheral edge 3a on the inner side and the inner box 2 has a peripheral edge 2a on the inner side so that the opening edge of the main body 1 of the storage has a predetermined thickness. A connecting portion 11 is provided so as to cover 2a and 3a.

As shown in FIG. 2, the connecting portion 11 is composed of a bent portion 11a, a bent portion 11b, and a main body portion 11c having a sectional shape corresponding to the opening edge portion of the main body 1 of the storage. A groove 11d and an insertion groove 11e, which communicates with the groove 11d and is formed substantially at the center of the groove 11d, is formed on the rear surface of the connecting portion 11 so that the bottom thereof is slightly wider. Then, the iron plate 12 is integrally embedded in the groove 11d of the connecting portion 11 at the same time when the vinyl chloride resin of the connecting portion 11 is extruded, and the heater 7 is further inserted from the direction of the arrow in the drawing so as to be in contact with the iron plate 12. R. The iron plate 12 is a galvanized steel plate.

The door 9 is formed so that the whole body 1 of the storage has a sealed structure corresponding to the opening of the main body 1 of the storage as shown by the broken line in FIG. The packing with magnet 10 is arranged at the corresponding position.

With the above configuration, the heat generated by the heater 7 inserted in the connecting portion 11 is directly conducted to the iron plate 12 having good thermal conductivity, and is further radiated through the resin layer formed to have a thin wall, so that the dew condensation on the periphery can be prevented. Prevent. Further, the iron plate 12 of the connecting portion 11 is adsorbed by the magnet-containing packing 10, and the door 9 seals the inside of the main body 1 of the storage, and the thin resin layer of the connecting portion 11 is the contact surface between the iron plate 12 and the magnet-containing packing 10. Is reinforced by the iron plate 12, and the contact surface of the magnet-containing packing 10 comes into contact with the flat resin, so that the door 9 absorbs and prevents the vertical movement indicated by the arrow in FIG.
