Field of the Invention The present invention relates to a heat insulating structure having an emblem on the front side of which a mark such as a character or a figure is displayed. 2. Description of the Related Art FIG. 3 shows a conventional structure in which a synthetic resin emblem showing a mark such as a character or a figure on the front side is attached to the surface of a heat insulating door for opening and closing a front opening of a heat insulating refrigerator body. . In this case, the refrigerator door 20 is filled with a foamable heat insulating material 23 between a door outer plate 21 formed of a painted steel plate or a stainless steel plate and a door inner plate 22 made of a synthetic resin to constitute a heat insulating door. I have. The surface of the heat insulating door 20 has an emblem 2
The emblem 25 made of a synthetic resin is adhered to the door outer plate 21 with a double-sided adhesive tape 24 in order to improve the workability of the mounting of the fifth embodiment. In addition, instead of the double-sided adhesive tape 24, a mounting leg is projected from the back side of the emblem 25, and the mounting leg is passed through a hole formed in the door outer plate 21.
There is also a method of screwing this leg to the back side of the door outer plate 21. [0004] In the former method,
Because it is only glued by double-sided adhesive tape 24
It has the feature of easy installation. However, the emblem may come off due to a decrease in the adhesive strength of the double-sided adhesive tape 24 due to aging. In particular, the door outer plate 21 formed of a stainless steel plate is easily damaged, and therefore, its surface is hardly damaged by a surface treatment with a chemical. In such a case, depending on the type of the surface treatment, the adhesive strength of the double-sided adhesive tape 24 is weak, and there is a problem that the emblem 25 peels off due to vibration or aging due to opening and closing of the refrigerator door 20. Also,
In the latter method, a mounting hole is required in the door outer plate 21, which complicates the structure and deteriorates the mounting workability. Accordingly, the present invention provides a method for easily mounting an emblem while taking advantage of the workability of a double-sided adhesive tape. In particular, in the present invention, when a surface plate of a stainless steel structure is employed, even in a state where the surface plate is subjected to a surface treatment with a chemical so as not to be easily damaged, without using the latter method, An object of the present invention is to provide a technique that allows an emblem to be easily attached and that can be stably held. According to the present invention, there is provided a heat insulating structure in which a foam insulating material is filled on the back side of a surface plate, wherein the surface plate has an emblem having a mark such as a character or a figure on the front side. An opening through which the foamed heat insulating material leaks in correspondence with an inner position of a back surface peripheral edge, wherein the emblem is adhered to the periphery of the opening with a double-sided adhesive tape to close the opening, and the foamed heat insulating material leaked to the opening; Is a heat insulating structure provided with an emblem, which is adhered to the back side of the emblem. [0007] Thus, even when the surface of the surface plate of a structure such as a refrigerator door is subjected to a surface treatment so as not to be easily damaged, the emblem of the structure is taken advantage of the workability of the double-sided adhesive tape. In the state where the emblem is attached to the surface plate, the emblem can be bonded at the same time as the heat insulating layer of the structure is formed by the foamed heat insulating material, so that the emblem can be easily held with sufficient strength. Next, an embodiment of the present invention will be described. Each drawing shows an embodiment of the present invention. FIG. 1 is a front view of a refrigerator-freezer according to the present invention, and FIG. 2 is a cross-sectional view of an emblem mounting portion of the present invention. In these figures, reference numeral 1 denotes a freezer-refrigerator, which is one of the cooling storages, which forms a plurality of storage compartments by partitioning the inside of the main body 2 which is entirely open, and the front of each of these storage compartments is opened and closed by a door. It is a configuration that can be done. The refrigerator-freezer main body 2 has an insulation structure in which a foam insulation material is filled between an outer box (outer wall plate) and an inner box (inner wall plate). Within the refrigerator-freezer body 2, a refrigerator compartment 3, a vegetable compartment 4, an upper freezer compartment 5, and a lower freezer compartment 6 are provided from above, and these compartments are respectively provided with a refrigerator compartment door 7, a vegetable compartment door 8, It is closed by an upper freezer compartment door 9 and a lower freezer compartment door 10 so that it can be opened and closed freely. The refrigerator door 7 has a foam insulating material 13 such as foam polyurethane filled between a door outer plate 11 made of a painted steel plate or a stainless steel plate and a door inner plate 12 made of a synthetic resin. Constructs an insulated door. Reference numeral 14 denotes an emblem attached to the upper front part of the refrigerator compartment door 7, and is made of a synthetic resin or metal on the front side of which the symbol such as the nickname, model name, trademark, etc. of the refrigerator 1 is represented in the form of characters, figures, or the like. It is made. Door skin 1
1 is a painted steel plate with a surface coating or SUS
It is made of stainless steel such as 430. In particular, in the present invention, when a stainless steel plate is used for the door outer plate 11, even when a surface protective film made of a chemical is formed on the surface of the stainless steel plate, the stainless steel plate can be achieved by the conventional mounting using only double-sided adhesive tape. It can provide an effective technology that has not been achieved. Reference numeral 15 denotes an opening formed in the door outer plate 11, which is an operating portion where the foamable heat insulating material 13 leaks in correspondence with the inner position of the back edge of the emblem 14. This opening 1
5 is preferably such that the foamable heat insulating material 13 adheres to the back surface of the emblem 14 with a sufficient area.
In the figure, the emblem 14 is formed to have a size corresponding to the entire inner region surrounded by the back surface periphery so as not to protrude from the back surface periphery. 16 is the opening 1
5 is a double-sided adhesive tape for adhering the emblem 14 to the door outer plate 11 in a region surrounding the periphery of the door 5, whereby the emblem 14 is adhered to the door outer plate 11 in a state of closing the opening 15. As described above, the emblem 14 is placed on the door outer plate 11 in a region covering the entire opening 15 and surrounding the opening 15.
In the state where the foam insulating material 1 is adhered to the space between the door outer plate 11 and the door inner plate 12, the undiluted solution of the foam insulating material 13 is filled.
3 is formed. Due to the formation of the heat insulating layer of the foam heat insulating material 13, the foam heat insulating material 13 adheres to the back side of the door outer panel 11, and a part of the foam heat insulating material 13 leaks from the opening 15 and the back side of the emblem 14. Glue to. Thereby, the emblem 14 is firmly fixed to the door outer plate 11. If the foam heat insulating material 13 is not bonded to the door skin 11, the door skin 11 may be
When separated from the door, there is a risk that the adhesion between the emblem 14 and the foamable heat insulating material 13 may be peeled off. However, the problem is eliminated by bonding the foamable heat insulating material 13 to the back side of the door outer plate 11. In the above description, the double-sided adhesive tape 16 adheres the emblem 14 to the door outer plate 11 and prevents the foamable heat insulating material 13 from leaking from a gap between the emblem 14 and the peripheral edge of the opening 15 of the door outer plate 11. Acts as a sealing material. Adhesion between the emblem 14 and the door outer panel 11 by the double-sided adhesive tape 16 is not for the purpose of fixing the emblem 14 to the door outer panel 11 by this adhesion alone, but rather serves as a sealing material for preventing the foamable heat insulating material 13 from leaking. The main purpose of this emblem is to provide the leakage preventing seal material with an adhesive function.
The main purpose is achieved by temporarily stopping the opening at a predetermined position that closes the opening 15. The double-sided adhesive tape 16 only needs to have at least such a function.
When 3 is filled, the emblem 14 maintains the state fixed to the door outer plate 11 by bonding with both the double-sided adhesive tape 16 and the foamable heat insulating material 13. The double-sided adhesive tape 16 may be disposed at least in a region around the periphery of the opening 15 of the door outer panel 11, but may be in a state of being bonded to the entire back surface of the emblem 14 as long as the material is bonded to the foamable heat insulating material 13. The emblem 14 is adhered to the entire back surface of the emblem 14 so as to close the opening 15 of the door outer plate 11.
Is more easily performed than the operation of arranging the double-sided adhesive tape 16 in a region around the periphery of the opening 15 of the door outer plate 11. As described above, the use of the double-sided adhesive tape 16 serves as a sealing material for preventing the leakage of the foamable heat insulating material 13 and closes the emblem 14 with the opening 15 for filling the foamable heat insulating material 13. In order to fulfill the role of attaching to the predetermined position, the structure is simplified and the leakage of the foamable heat insulating material 13 is simplified as compared with a method in which the sealing material for preventing the foam heat insulating material 13 from leaking and the emblem 14 are separately mounted. Can be performed accurately. Further, according to the present invention, the door outer plate 11 constituting the surface of the refrigerator door 7 is made of stainless steel, and the surface thereof is subjected to a surface treatment with a chemical so as not to be easily damaged, and the double-sided adhesive tape 16 is adhered. Even if the force is weak, even if the adhesion by the double-sided adhesive tape 16 is weak, if the leakage of the foamable heat insulating material 13 can be prevented during the foam filling of the foamable heat insulator 13 as described above, the foam heat insulating material 13 After foam filling
The emblem 14 can be stably held on the door outer plate 11 by bonding with the foamable heat insulating material 13 through the opening 15. The above embodiment is directed to the refrigerator compartment door 7 of the refrigerator 1 as a surface plate of the structure.
The present invention can also be applied to a structure in which an emblem is attached to a surface plate of a heat insulating structure, such as another structure that replaces the refrigerator compartment door 7, for example, a constant temperature cabinet, a vending machine, a food showcase, and the like. For this reason, the present invention is not limited to the above-described embodiment, but can be applied to cooling storages and other heat-insulating structures, and various modifications are possible without departing from the technical scope of the present invention. It encompasses forms. According to the first aspect of the present invention, the structure is simple because the adhesive strength of the double-sided adhesive tape and the effect of preventing leakage of the foamable heat insulating material can be obtained. In addition, even if the surface of the surface plate of the structure such as a refrigerator door is surface-treated so as not to be easily scratched, the emblem is attached to the surface of the structure by taking advantage of the workability of the double-sided adhesive tape. In this state, the emblem can be bonded at the same time as the heat insulating layer of the structure is formed with the foamed heat insulating material, so that even if the adhesive strength with the double-sided adhesive tape is weak, the emblem can be easily held and maintained with sufficient strength It is.
