The present invention relates to a refrigerated showcase having a refrigerator structure in a transparent structure. Two or more transparent plates are opposed to each other via spacers, and they are joined together by surrounding frame members. In recent years, refrigerated showcases that form transparent refrigerator rooms have become popular.

In this case, since the inside of the refrigerator is cooled, the moisture contained in the internal space condenses on the inner surface of both transparent plates.

In general, this treatment is to fill a large amount of particulate desiccant in the space or to insulate a gas with a higher specific gravity and less convection than air in the space, for example, argon or hexafluoride (SF ₆ ) to reduce condensation. Is being employed.

For example, Japanese Unexamined Patent Application Publication No. 1-25875 discloses a multi-layered transparent plate using a combination of the filling of the desiccant and the encapsulation of the insulating gas (G).

As mentioned above, filling of the desiccant or encapsulation of the insulating gas is effective to prevent condensation. However, the manufacturing process is complicated, resulting in high cost and moisture absorption of the insulating gas or desiccant in the long-term use. There was a problem in that the effect of preventing condensation was insufficient due to lowering of the action.

SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerated showcase constructed by using a multi-layered transparent plate that can exhibit almost no condensation preventing effect without using an insulating gas or a desiccant, and has a very simple structure and assembly. do.

In the present invention, two transparent plates face each other, a spacer is interposed in a frame shape at the peripheral edges of the mutually opposing faces of the transparent plate, and both transparent plates are bonded through the spacers, and a plurality of layers having a space therein. In the refrigerated showcase which comprises the transparent plate of this, and formed the refrigerator room by this multiple layer transparent plate, the corner part of the transparent plate inside a refrigerator among the two transparent plates which comprise the above-mentioned multiple layer transparent plate Part of the inner space is cut through so as to pass through the inside of the refrigerator to form a hole through each other.

In addition, by cutting a part of the end of the above spacer to provide a through hole for passing through the internal space and the inside of the refrigerator one after another.

Even if there is moisture in the space of the multi-layered transparent plate, the moisture enters into the refrigerator from successive holes formed by cutting in the corners of the transparent plate inside the refrigerator, evaporates into the refrigerator, and condensation does not occur on the inner surface of the transparent plate. .

In addition, successive holes having the same function can be formed by cutting a part of the spacers of the plurality of transparent plates to dissipate moisture in the space.

Example

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The cooling showcase 1 is formed of a plurality of transparent plates 2. And the front side with the handle 4 as a refrigerated showcase in which the transparent refrigerator compartment 3 is formed so that opening and closing is free, and the shelf part 5 ... You can take out the food you put in.

The well-known cooling apparatus is accommodated in the lower machine room 6. A plurality of layers of transparent plates forming each side of the refrigerator chamber 3 face two transparent plates, for example, glass plates at predetermined intervals, so that spacers are provided at the peripheral edges of the mutually opposing surfaces of the two transparent plates. By interposing the spacer and the transparent plate by using an adhesive or the like, the space surrounded by the spacer and both transparent plates is formed inside.

2 and 3 show the structure of the multi-layered transparent plate according to the first embodiment of the present invention, and FIG. 4 is a perspective view of the refrigerator room formed by using the multi-layered transparent plate as viewed from the inside of the refrigerator. to be.

In each figure, 10A and 10B are two mutually opposing transparent plates. The spacer 11 is described on the peripheral edges of the mutually facing surfaces 12a and 12b of the two transparent plates 10A and 10B to hold the transparent plate at predetermined intervals, and so on as a resin member. It is formed, and as shown in FIG. 3, the cross section shows a concave shape, and the protruding edges 14a and 14b and the transparent plate 10A which abut on the edges 13a and 13b of the transparent plates 10A and 10B. The spacer portion 15 is sandwiched between the portions 10B.

The spacer 11 and the transparent plates 10A and 10B are in contact with each other, that is, between the protruding edges 14a and 14b of the edges 13a and 13b and between the transparent plates 10A and 10B. An adhesive or the like is applied between the opposing surfaces 12a and 12b and both side portions of the spacer portion 15 so that the three plates of the transparent plate 10A, 10B and the spacer 11 are integrally combined and have an internal space. The multilayer transparent plate 2 in which the 17 was formed is comprised.

However, one of the two transparent plates 10A and 10B constituting the multilayer transparent plate 2, that is, the transparent plate located inside the refrigerator when the refrigerator compartment 3 is assembled. Cut the corners of to 45 degrees. In this way, successive openings 18 are formed so that the interior space 17 and the refrigerator compartment 3 pass through each other.

In this case, as shown in FIG. 4, the refrigerator 18 is assembled by using the plurality of transparent plates 2, with the holes 18 passing through them in the upper side.

In this way, when the cold air in the refrigerator enters the interior space 17 through the holes 18 through which the air flows in succession, it descends to the lower portion of the refrigerator and spreads to the entire interior space 17 so that the air in the interior space 17 and the air in the refrigerator Ventilation is performed more effectively than when the continuous holes 18 are connected to the lower side, and evaporation of dew attached to the inner surfaces of the transparent plates 10A and 10B is performed quickly in time.

In the formation of the refrigerator compartment 3, as shown in FIG. And the frame member 20 is used for coupling with the multi-layered transparent plate 2 on the ceiling surface.

The frame member 20 includes a frame plate body 21 and a frame plate body 21 which have a shape such as to be generally fitted to the upper portion with respect to the spacer 11 and the transparent plates 10A and 10B. It consists of a cover frame 22 to be combined, and between the surface 21a extending slightly inclined upwardly protruding into the refrigerator installed in the frame body 21 and the bent edge 22a of the cover frame 22. Insert the multi-layered transparent plate 2 on the ceiling surface.

By the above structure, each multiple layer transparent board 2... Since the interior space 17 of the interior space 17 is in a situation where all of the interior spaces communicate with the refrigerator through the successive openings 18, the moisture contained in the interior space 17 is led to the refrigerator compartment 3 side to evaporate and transparent plate 10A. It is possible to prevent the occurrence of condensation on the inner surface of the 10B.

5 to 8 show a structure in which a part of the spacer 11 is cut so that the internal space 17 and the refrigerator compartment 3 pass through each other in this embodiment.

As shown in FIG. 6 and FIG. 8, the half of the spacer 11 located inside the refrigerator is transmitted to the predetermined length dimension L. As shown in FIG.

That is, the inner half of the refrigerator and the protruding edge 14b of the spacer portion 15 of the spacer 11 are cut together, and a hole 26 is provided to connect to the refrigerator.

Thus, it is provided by a method of forming a passage portion 28 which is connected to the successive openings and leads to the internal space 17 so as to dent the inner surface side portions of the successive holes 26 and the corresponding frame plate 21. Doing.

As the hole 26 and the passage part 28 which communicate in succession, the state which communicates between the internal space 17 and the inside of a refrigerator is achieved. In addition, the vertical wall portion of the frame body 21 other than the passage path 28 is in close contact with the outer surface of the transparent plate 10B, that is, the refrigerator inner surface 30.

Thus, as shown in FIG. 7, the interior spaces 17 of each of the multi-layered transparent plates 2 and the refrigerator are connected in series, and the moisture and moisture in the interior spaces 17 enter the refrigerator as shown by arrows, and evaporate there to make the multiple layers transparent. Condensation on the inner surface of the plate 2 is prevented.

As described above, according to the present invention, the refrigerator compartment composed of the multi-layered transparent plate and the inner space of the multi-layered transparent plate are formed of a series of holes or two special plates provided in the cut part of the corners of the transparent plate located at the side of the refrigerator chamber. The situation in which the continuous communication is achieved through the successive through holes formed by cutting a portion of the spacers spaced apart from each other can be achieved, so that the air in the space and the air (chill) in the refrigerator are smoothly ventilated and thereby Moisture and moisture contained will move inside the refrigerator and evaporate.

Therefore, condensation does not occur on the inner surface of the transparent plate. It is possible to prevent condensation with a very simple configuration and to facilitate manufacturing assembly and to reduce costs without adopting a dehumidifying method of filling a desiccant in an internal space as in the prior art.
