DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated underfloor storage, for example, provided under a kitchen floor for storing foods and the like.

[0002]

2. Description of the Related Art In general, an insulated underfloor storage is capable of effectively utilizing the underfloor space of a building so that a room can be widely used, and is maintained at a relatively low temperature throughout the year and has little temperature fluctuation. Therefore, it is used for storing food products that can be stored for a relatively long time, such as canned goods and seasonings.

A conventional insulated underfloor storage is disclosed in Japanese Utility Model Laid-Open No. 3-11.
As disclosed in Japanese Patent No. 1739, an opening is formed in a floor plate, and the periphery of the opening is covered with a metal frame material. Then, a gasket is interposed between the periphery of the opening and the lid to prevent heat transfer due to passage of cool air.

[0004]

However, in the conventional insulated underfloor storage, heat transfer due to the passage of air between the frame and the lid is prevented, but the upper end of the frame is in the indoor space. And the lower end is exposed to the underfloor space, so that heat conduction occurs between the underfloor space and the indoor space using the frame material as a medium. For example, in winter, there is an inconvenience that cold heat under the floor is transmitted to the room using the frame material as a medium, thereby reducing the indoor heating effect. In addition, there is a disadvantage that in the summer, indoor cool air escapes below the floor using the frame material as a medium, thereby lowering the indoor cooling effect.

Accordingly, an object of the present invention is to provide a heat-insulated underfloor storage that can enhance the heat insulation between a room and an underfloor space.

[0006]

In order to achieve the above object, the invention according to the first aspect of the present invention is directed to an indoor side member in which a frame material of an insulated underfloor storage mounted on an opening side wall of a floor is brought into contact with a lid. And a lower-floor member supporting the storage container, and a heat-insulating member. The heat-insulating member has one side in contact with the opening side wall and the other side in contact with the indoor-side member and the lower-floor member. The side member is separated and held, and a tight material is provided at this separation position to abut the lid. According to the first aspect of the present invention,
Since the indoor side member and the underfloor side member are provided separately on one side of the heat insulating member, the transfer of heat between the room and the underfloor space where the frame material of the underfloor storage is to be transmitted as a medium, It is cut off by the separation between the indoor side member and the under floor member.
Therefore, heat insulation between the room and the underfloor space using the underfloor member and the indoor member as a medium can be achieved. Moreover, since the space between the indoor side frame member and the outdoor side frame member and the opening side wall is air-tightly held by the heat insulating member, the movement of air between the indoor side frame member and the outdoor side frame member and the opening side wall is caused. Cut off heat transfer. Further, the air passage between the indoor side frame member and the outdoor side frame member and the lid is blocked by a tight material to prevent heat transfer in the air passage. As described above, the insulated underfloor storage of the present invention enhances heat insulation between the underfloor and the room.

According to a second aspect of the present invention, in the first aspect of the present invention, the lid of the insulated underfloor storage is provided with a heat insulating material at a lower portion, and a tight material is brought into contact with a lower end of the lid. It is a feature. According to the second aspect of the present invention, it is possible to prevent the heat between the storage container and the room from being transmitted using the lid as a medium, and to further enhance the heat insulation between the underfloor and the room.

A convex portion 15 facing downward is formed at an end of the flange 13 so as to engage with the concave portion 17 of the frame member 8.

The frame member 8 is composed of a profile member 9 and a plywood (heat insulating member) 27 for supporting the profile member 9. The profile member 9 has a groove (a gap) formed between the indoor member 31 and the underfloor member 33. ) 29. The profile 9 is made of an extruded profile of an aluminum alloy, and the lower end 9 a of the profile 9 is a screw 20.
Is fixed to a substantially L-shaped support piece 23 via the. The support pieces 23 are fixed to the floor frame member 19 with screws 21. The lower end 9 a is in contact with and supports the storage container 7, and is thermally exposed to the underfloor space via the support piece 23.

The upper end 9b of the profile 9 extends from the opening edge onto the floor plate, is locked to the floor plate 3, and is fixed to the floor plate 3 by screws 25. The shape member 9 is formed in a U-shaped cross section bulging toward the storage container 7 at a central portion 9c between the upper end portion 9b and the lower end portion 9a. Is provided with a plywood 27 as a heat insulating member for supporting the profile 9. The heat insulating member is not limited to plywood, but may be a resin material. This plywood 27
Is to support the shaped member 9 separated into the indoor side member 31 and the under floor member 33 and stably attach the shaped member 9. The interior side member 31 is configured such that the lid comes into contact with a shoulder protruding from the lid 11 via a tight material (described later) 43.

A groove (gap) 29 is formed in the central portion 9c of the profile 9 so as to divide the profile into a room-side member 31 and an underfloor member 33. The groove 29 is conducted through the profile 9. It prevents heat transfer between the room and the underfloor space. The indoor member 31 and the underfloor member 33 separated by the groove 29 are fixed to the plywood (heat insulating member) 27 by screws 35 and 37, respectively. The groove 29 is formed at a position of a tight material that keeps an air passage between the frame member 9 and the lid 11 airtight, and the underfloor member 33 that transmits heat of the underfloor space to the air passage is connected to the indoor side. It is thermally separated from the member 31.

A base 39a of a tight material 39 for keeping the space between the cover 29 and the lid 11 airtight is fitted into the groove 29, and is used for holding the tight material 39. That is, as shown in FIG. 2, irregularities 41 are respectively formed at the lower end of the indoor side member 31 and the upper end of the underfloor member 33 forming the groove 29, and the base 39 a of the tight material 39 is formed on the irregularity 41. Mated.

The shape member 9 is provided with a tight member 43 which is in close contact with the lid 11 at the indoor side member 31 so that a double airtight structure is formed between the shape member 9 and the lid 11. ,
The airtightness and heat insulation in the storage container 7 are improved.

The lid 11 is provided so as to open and close the opening 5 of the floor plate.
It is fixed by. Reference numeral 49 denotes a handle for opening and closing the lid 11.

Next, a method of manufacturing the frame member 8 will be described with reference to FIGS. In the method shown in FIG. 2, the indoor member 31 and the underfloor member 33 of the profile 9 are separately manufactured, and are arranged on the plywood 27 so as to form a groove (gap) between them. At this time, the base 39a of the tight material 39 is
9, and in this state, the indoor side member 31 is attached to the plywood 27.
And the underfloor member 33 are fixed by screws.

In another method of manufacturing the frame member 8, as shown in FIG. 3, as shown in FIG. 3A, the profile member 9 in which the indoor member 31 and the underfloor member 33 are integrally formed is formed as shown in FIG. Then, as shown in FIG. 3 (B), the shape member 9 is cut with a cutter or a saw so as to form the groove 29.
