Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to underfloor storage for cold regions.

(Prior Art) Conventional underfloor storage simply utilizes the area under the floor for storage, or in the case of a well-ventilated area under the floor, utilizes the cooling effect of the cold air.

(Problems to be solved by the invention) Conventional underfloor storage is for the above-mentioned purposes, so in cold regions, the interior becomes like a freezer in the winter, making it impossible to store vegetables. For this reason, for example, in Hokkaido, underground storage methods have traditionally been used in which a ``muro'' is built underground with concrete or wood and accessed using a ladder from under the floor, but access is cumbersome and water from melting snow flows in. There was a problem. However, in winter, ``Muro'' was effective for storing overwintering vegetables, fruits, sake, soy sauce, drinks, etc. without freezing them.

(Means for solving the problem) This idea is based on the idea of trying to achieve the same antifreeze effect as the above-mentioned "Muro" by storing it under the floor, instead of underground storage, which has problems in terms of equipment and use. The outline is that it is an underfloor storage that is hung by fitting the supporting flange on the upper edge of a box-shaped box to the edge of a rectangular floor hole in a heated indoor room. and the opposite wall of the box,
A band-shaped steel plate reinforcing these is bent along the same groove shape around the outer periphery of the three groove-shaped sides consisting of the bottom, and both ends of the band-shaped steel plate are fixed to the support flange, and the thickness is adapted to the outer periphery of the box body. A box-shaped insulation material made of urethane foam with a diameter of 10 to 20 mm is placed in the box together with the steel strip.
This underfloor storage for cold regions is characterized by being covered up to the point where it touches the support flange.

(Function) The storage cabinet of this invention has achieved the purpose of achieving the same anti-freezing effect as the above-mentioned ``Muro'' even in under-floor storage cabinets in ordinary households. In other words, the storage is a simple thin box made of rust-free metal plates in the shape of a box with a support collar attached, a steel band plate wrapped around it for reinforcement, and a thin urethane foam cover on the outside. Because it is covered with a thick layer, it is simple enough to be used as a household storage cabinet, and has an insulating effect that protects the interior from freezing even in the coldest months. Even if the urethane foam is only 10mm thick, it can block the cold air under the floor and protect the inside of the refrigerator from freezing during the severe cold season in Hokkaido.

The reinforcing steel strip is in the form of a groove-shaped band hanging from the support collar, and when a large amount of food such as canned food is placed in the thin plate storage, it takes on a percentage of the weight. However, unlike conventional plate surface reinforcement, there is no need to fix the plate and the reinforcing material, so there is no distortion or protrusion of the plate due to welding, rivets, etc., and no machining is required.

Moreover, since this strip-shaped steel plate runs along the outer surface of the box, it has the advantage that there is no problem at all when placing a urethane foam cover that matches the external dimensions of the storage over the storage.

(Example) Figures 1 and 2 show an example of this invention, and its main parts are a horizontal part 1a that is made of rustless metal flange material and is placed on the flooring material F; A support flange 1 consisting of a middle section 1b with an L-shaped cross section that receives the lid plate A (Fig. 4) inside, and a vertical section 1c that hangs down from the inner edge of the middle section 1b. A box 3 made of a thin plate of rust-free metal is fixed and hung, and is attached to the vertical part 1c via the upper edge of the box 3 with the rivets or screws 2, and the opposite wall 3a of the box 3,
3a, a band-shaped steel plate 4 for reinforcing the bottom part 3b, and a box-shaped heat insulator installed so as to cover the box body 3 and the band-shaped steel plate 4 from the outside with a thickness that does not protrude from the lower surface of the support flange middle part 1b. The material is grade 5.

The main parts are shown enlarged in Figures 3 and 4, but the support flange 1
As shown in Fig. 4, the horizontal part 1a is placed on the flooring material F to support the weight of the box 3 and its stored items, the cover plate A is aligned with the floor surface to receive and support it, and the box 3 is easy to install. In addition to providing a vertical surface, it also provides a new mounting location for the strip steel plate 4 and a location for mounting the heat insulating urethane foam 5 so that it does not protrude beyond the hole in the flooring material F. The horizontal portion of the middle support flange portion 1b that receives the edge of the cover plate A serves to accommodate the urethane foam 5 inside the floor hole.

In this embodiment, an aluminum alloy is used as the stainless metal, the support flange 1 is 1.5 to 2.0 mm thick, the box body 3 is 0.6 mm thick, and the steel strip 4 is 0.6 mm thick and 60 mm wide. This is sufficient to support a large product with an internal volume of 1500 mm long and 560 mm wide, up to the illustrated embodiment with a depth of 420 mm and length and width of 560 mm. The insulation material 5 is only 10 mm thick, and it has been confirmed that by using urethane foam with good insulation performance, freezing can be prevented even in the severe cold of Hokkaido.

In this embodiment, the strip-shaped steel plates 4 are attached to the collar 1 by crossing each other vertically and horizontally, but for example, two strips may be arranged in the same direction in parallel, or the width of one may be made narrower.
It is up to the designer to increase the number of pieces. Strip steel plate 4
In principle, there is no need for rivets to be attached to the box body 3, but in this embodiment only one rivet is used at the center of the bottom to prevent positional movement. Since the box body 3 is suspended by the band-shaped steel plate 4 fixed at both ends to the collar 1, there is no need to integrate the box body 3 and the band-shaped steel plate 4, which is advantageous in terms of appearance and required man-hours.

In addition to having a heat retaining effect, the box-shaped heat insulating material 5 covers the strip steel plate 4 and is integrated with the box body 3 to protect the steel plate 4 from outside air and moisture, and also serves as the overall packaging body.

In addition, in this embodiment, the window 6 (third
), and a group of small holes 7 are opened in the corresponding positions of the box body 3 to provide ventilation. This corresponds to the fact that in relatively warm regions, ventilation is more important than prevention of freezing, so in cold regions, only the box-shaped insulation material 5 is used for
It is sufficient to close the small hole group 7 using something that has no holes.

(Effect of the invention) The underfloor storage for cold regions of this invention prevents cold air under the floor.
It is isolated by the metal box and the urethane foam box-shaped insulation material that covers it, and heated indoor air enters every time the upper opening lid is opened, so the temperature inside the refrigerator drops below 0℃ even in the coldest months. It works in the same way as the ``Muro'' mentioned above.

In addition, this idea has a unique reinforcing structure in which a strip-shaped thin steel plate is wrapped around the storage box body, and both ends are fixed to the support flange for hanging.This means that expensive rustless metal plates can be replaced with thin plates, and the box body can be reinforced. There is almost no welding distortion or protrusion of the rivet heads, which is common in other machines, and the reinforcing material does not protrude, so it has the advantage of being able to cover it with square-shaped urethane foam insulation that matches the outer shape of the storage compartment, and the hole in the floor into which it is sunk is also just a square. An added advantage is that a hole is sufficient.

With this invention, the underfloor storage in ordinary households, which was considered unable to store vegetables during the winter in cold regions, can now be used in the same way as ``Muro'', which is extremely convenient.
