Japanese Unexamined Patent Publication No. 2005-090810

The heat insulating box may be filled with foam insulation by arranging the back plate upward, and at this time, the hot melt adhesive flows down on the side plate, and the unfilled area of the hot melt adhesive is formed in the groove. May be formed. Since the width of the groove is narrow, the unfilled region is not filled with the foamed heat insulating material, and voids are generated. For this reason, when the gas generated during the foaming of the foamed heat insulating material is confined in the void, the outer box partially expands due to the expansion of the gas, which causes a problem that the appearance of the refrigerator is deteriorated.

An object of the present invention is to provide a refrigerator capable of preventing poor appearance.

In order to achieve the above object, the present invention provides a refrigerator provided with a heat insulating box body in which a foamed heat insulating material is filled between the inner box and the outer box, and a heat radiating pipe arranged on the inner surface of the outer box and extending in the vertical direction.

It has a back plate that is inserted into the second groove and is elastically supported, and an airspace is formed inside by arranging the heat radiation pipe in the opening in front of the first groove, and the airspace is the heat insulating. It is characterized by communicating with the outside of the box.

Further, the present invention is characterized in that, in the refrigerator having the above configuration, the heat radiating pipe is extended to the outside of the heat insulating box body in a state of being arranged in the opening.

Further, in the refrigerator having the above configuration, the heat radiating pipe is fixed to the side plate by an adhesive tape extending in the vertical direction and extended below the heat insulating box, and the lower end of the adhesive tape is inside the inside. It is characterized in that it is arranged between the lower end of the back surface of the box and the lower end of the back surface of the outer box.

Further, the present invention is characterized in that, in the refrigerator having the above configuration, a tubular member for connecting the airspace and the outside of the heat insulating box is provided.

Further, in the refrigerator having the above configuration, the heat radiating pipe is fixed to the side plate by an adhesive tape extending in the vertical direction, and the lower end of the heat radiating pipe is bent away from the opening to insulate the heat. A bent portion extending below the box body is provided, and the adhesive tape covers the opening below the bent portion and extends outside the heat insulating box body.

<First Embodiment>
An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a refrigerator 1 according to a first embodiment of the present invention. The refrigerator 1 has a heat insulating box body 10, and a machine room 70 is arranged below the rear portion of the heat insulating box body 10. The heat insulating box body 10 is formed by filling a foamed heat insulating material 13 (see FIG. 3) such as urethane foam between the outer box 11 and the inner box 12. A compressor (not shown) for operating the refrigeration cycle is arranged in the machine room 70.

The inner box 12 is made of a resin molded product, and is divided into a plurality of cooling chambers having an open front surface.

The outer box 11 is made of a metal plate such as a decorative steel plate, and is formed in a box shape having an open front surface by a top plate 11a, side plates 11b, 11e, a back plate 11c, and a bottom plate 11d. The back plate 11c and the bottom plate 11d are formed separately from the top plate 11a and the side plates 11b and 11e.

A heat radiating pipe 34 and a vacuum heat insulating material 21 are arranged on the inner surfaces of both side surface plates 11b and 11e. The heat radiating pipes 34 extend in the vertical direction and are arranged in a plurality of rows in the front-rear direction by meandering. The heat radiating pipe 34 is connected to the refrigerant discharge side of the compressor (not shown), and the heat of the refrigerant flowing inside the heat radiating pipe 34 is radiated through the outer box 11.

The vacuum heat insulating material 21 is attached to the inner surfaces of the side plates 11b and 11e by a double-sided adhesive tape or the like, and the core material 25 (see FIG. 3) is included in the bag-shaped outer cover material 26 (see FIG. 3). The core material 25 is formed by laminating a plurality of non-woven fabrics (not shown). The inside of the outer cover material 26 is evacuated so that the core material 25 acts as a spacer to reduce the pressure, and the core material 25 is sealed inside the outer cover material 26.

FIG. 2 is a plan view showing a part of the outer box 11 in an unfolded manner. Side plates 11b and 11e are connected to both sides of the top plate 11a, and the side plates 11b and 11e are bent from the unfolded state to form the outer box 11. The back plate 11c and the bottom plate 11d (see FIG. 1) are attached to the side plates 11b and 11e.

Each row of the heat radiating pipe 34 is attached to and fixed to the inner surface of the outer box 11 by adhesive tapes 41 to 44 extending in the stretching direction. The adhesive tapes 41 to 44 are made of a metal foil adhesive tape having a metal foil such as an aluminum foil. As a result, the heat of the refrigerant flowing through the heat radiating pipe 34 can be efficiently conducted to the outer box 11 to enhance the heat radiating effect.

FIG. 3 shows a top sectional view of the right rear portion of the heat insulating box body 10. The left rear portion of the heat insulating box 10 is similarly formed. At the rear end of the side plate 11e, a mounting portion 50 having a first groove 51 that is bent in an S shape and has an open front and a second groove 52 that has an open rear is provided. The mounting portion 50 is formed so as to extend from the upper end to the lower end of the side plate 11b.

Insert pieces 60 that bend forward are provided at both end portions of the back plate 11c. The insertion piece 60 is inserted into the second groove portion 52, and the back plate 11c is elastically supported by the elasticity of the mounting portion 50. As a result, the back plate 11c is fixed to the side plates 11b and 11e.

Further, the back plate 11c is opened with an injection port 7 (see FIG. 5) for injecting the undiluted solution of the foamed heat insulating material. The injection ports 7 are arranged side by side in the vertical direction at two locations on both sides of the back plate 11c in the left-right direction.

The last row of heat dissipation pipes 34 are arranged in front of the opening 51b in front of the first groove 51. As a result, the heat radiation pipe 34 in the last row prevents the foamed heat insulating material 13 from flowing into the first groove portion 51, so that an air space 51a is formed inside the first groove portion 51. The airspace 51a extends in the vertical direction along the heat radiating pipe 34 and communicates with the machine room 70 (see FIG. 1) as described later.

The adhesive tape 44 is attached by connecting the upper part of the mounting portion 50 and the upper side plate 11e in front of the mounting portion 50, and abuts the heat radiating pipe 34 on the opening 51b. A gap S in the front-rear direction is provided between the vacuum heat insulating material 21 and the adhesive tape 44.

FIG. 4 is an enlarged plan view showing the lower end portion of the side plate 11e. The alternate long and short dash line in the figure indicates the bottom plate 11d and the inner box 12. An external machine room 70 of the heat insulating box 10 is arranged below the bottom plate 11d.

A bent portion 34a is provided at the lower end of the heat radiating pipe 34. The bent portion 34a bends in a direction away from the opening 51b of the first groove portion 51, extends below the bottom plate 11d, and extends to the machine room 70.

Further, the adhesive tape 44 extending in the vertical direction covers the opening 51b below the bent portion 34a and extends below the bottom plate 11d. As a result, the opening 51b at the lower end of the first groove 51 away from the heat radiating pipe 34 is closed by the adhesive tape 44, and the airspace 51a (see FIG. 3) communicates with the machine room 70.

FIG. 5 is a perspective view showing a state of the heat insulating box 10 when the foamed heat insulating material 13 is filled. In the figure, the arrow L indicates the flow direction of the stock solution of the foamed heat insulating material 13. The undiluted solution of the foamed heat insulating material 13 injected from the injection port 7 of the heat insulating box 10 arranged with the front surface facing downward flows down along the side plates 11b and 11e.

The undiluted solution of the foamed heat insulating material 13 accumulates in the front part of the heat insulating box 10 below, and then rises while foaming along the side plates 11b and 11e, the top plate 11a and the bottom plate 11d. After that, the foamed heat insulating material 13 that has reached the back surface of the inner box 12 advances toward the central portion between the back plate 11c of the outer box 11 and the back surface of the inner box 12. As a result, the foamed heat insulating material 13 is filled between the inner box 12 and the outer box 11.

At this time, the opening 51b in front of the first groove 51 is closed by the heat radiating pipe 34, and the foamed heat insulating material 13 does not enter the first groove 51. Therefore, an airspace 51a communicating with the outside can be formed in the first groove portion 51.

The gas generated during the foaming of the foamed heat insulating material 13 flows into the first groove portion 51 from the upper ends of the side plates 11b and 11e on which the heat radiating pipe 34 is not provided. If the foaming of the foamed heat insulating material 13 further progresses, the foamed foamed heat insulating material 13 may cover the periphery of the first groove portion 51, and the gas flowing into the first groove portion 51 may be trapped. In this case, the gas trapped in the first groove 51 expands or contracts due to the temperature change in the foaming process to deform the outer box 11, resulting in poor appearance.

However, in the present embodiment, an airspace 51a communicating with the first groove portion 51 in the vertical direction is formed, and the airspace 51a further communicates with the machine room 70. Therefore, the gas that has flowed into the first groove 51 is discharged to the machine room 70 outside the heat insulating box 10 through the airspace 51a. Therefore, the inside of the airspace 51a of the first groove 51 is maintained at atmospheric pressure, and the deformation of the outer box 11 can be reduced.

Further, since the back surfaces of the adhesive tapes 41 to 44 are subjected to a mold release treatment, when the vacuum heat insulating material 21 and the adhesive tape 44 overlap each other, the foam heat insulating material 13 enters between them. As a result, the side plates 11b and 11e are deformed by the foaming of the foamed heat insulating material 13. Therefore, by providing a gap S (see FIG. 3) in the front-rear direction between the vacuum heat insulating material 21 and the adhesive tape 44, the foam heat insulating material 13 between the vacuum heat insulating material 21 and the side plates 11b and 11e can be provided. Invasion is prevented. Therefore, the deformation of the outer box 11 can be further reduced.

According to the present embodiment, the heat radiating pipe 34 is arranged in the opening 51b in front of the first groove 51 provided at the rear end of the side plates 11b and 11e of the outer box 11 so that the heat dissipation pipe 34 is inside the first groove 51. An airspace 51a communicating with the outside is formed. As a result, the heat radiating pipe 34 is arranged at the rear ends of the side plates 11b and 11e and kept away from the inside of the refrigerator, so that heat can be radiated efficiently. Further, the opening 51b of the first groove 51 is closed to prevent the generation of voids due to the partial inflow of the foamed heat insulating material 13 into the first groove 51, and the gas at the time of foaming passes through the airspace 51a to the heat insulating box. It is discharged to the outside of 10. Therefore, it is possible to prevent the outer box 11 from being deformed and to prevent the refrigerator 1 from having a poor appearance.

Further, the adhesive tape 44 covers the opening 51b below the bent portion 34a away from the opening 51b of the heat radiating pipe 34 and extends to the outside of the heat insulating box body 10. As a result, the airspace 51a above the bent portion 34a and the machine room 70 communicate with each other through the first groove portion 51 in which the opening 51b is closed with the adhesive tape 44. Therefore, the gas that has flowed into the airspace 51a can be reliably discharged to the outside of the heat insulating box body 10.

Further, a gap S in the front-rear direction (see FIG. 3) is provided between the vacuum heat insulating material 21 and the adhesive tape 44), and the vacuum heat insulating material 21 is separated from the adhesive tape 44 which has been subjected to the mold release treatment. Therefore, the foam heat insulating material 13 is prevented from entering between the vacuum heat insulating material 21 and the side plates 11b and 11e, and the deformation of the outer box 11 can be further reduced.

<Second Embodiment>
Next, FIG. 6 is a top sectional view showing a right rear portion of the heat insulating box body 10 of the refrigerator 1 according to the second embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 5 will be designated by the same reference numerals and the description thereof will be omitted. In this embodiment, the sticking range of the adhesive tape 44 is different from that in the first embodiment. Other parts are the same as those in the first embodiment.

The adhesive tape 44 for fixing the heat radiating pipe 34 on the opening 51b of the first groove 51 is attached by connecting the top of the mounting portion 50 and the top of the heat radiating pipe 34. As a result, the front end of the adhesive tape 44 is arranged on the heat radiating pipe 34. Therefore, the air space 53 (see FIG. 3) between the adhesive tape 44 and the side plate 11b is not formed in front of the heat radiating pipe 34. This makes it possible to prevent the outer box 11 from being deformed by the gas trapped in the airspace 53.

Further, since the front end of the adhesive tape 44 does not reach the side plates 11b and 11e, the vacuum heat insulating material 21 is brought closer to the heat radiating pipe 34 while ensuring a predetermined gap S between the vacuum heat insulating material 21 and the adhesive tape 44. be able to. Therefore, the area of the vacuum heat insulating material 21 attached to the side plates 11b and 11e can be increased, and the heat insulating performance of the refrigerator 1 can be improved.

As shown in FIG. 5 above, the foamed heat insulating material 13 rises while foaming along the side plates 11b and 11e, the top plate 11a and the bottom plate 11d. At this time, the foamed heat insulating material 13 rising along the side plates 11b and 11e near the lower end 81 on the back surface of the inner box 12 tends to flow in the direction of the bottom plate 11d. Therefore, it is difficult for the foamed heat insulating material 13 to enter the first groove 51 at the rear end of the side plates 11b and 11e.

In this way, when the lower end 81 on the back surface of the inner box 12 and the lower end 82 on the back surface of the outer box 11 are appropriately separated from each other, the lower end 81 on the back surface of the inner box 12 and the bottom plate 11d on the upper surface of the machine room 70 The foamed heat insulating material 13 easily flows between the two. Therefore, even if the lower end of the first groove 51 is not blocked by the heat radiating pipe 34 and the adhesive tape 44, the airspace 51a can communicate with the machine room 70.

Thereby, the same effect as that of the first embodiment can be obtained. In addition, the amount of the adhesive tape 44 used can be reduced to reduce the cost of the refrigerator 1.
