FIG. 2B is a diagram for explaining a portion of the heat insulating door 8A shown in FIG. 2A where the foamed heat insulating material 15 is likely to be peeled off by opening and closing the heat insulating door 8A. Although there are variations depending on the height of the user and the like, in many cases, the user holds around the lower portion Q1 of the heat insulating door 8A when opening the heat insulating door 8A. When the lower part Q1 is gripped and the heat insulating door 8A is repeatedly opened and closed, the portion corresponding to the region T1 in FIG. This region T1 is a region on the diagonal line of the heat insulating door 8A, that is, a region extending from the lower part Q2 side on one side of the heat insulating door 8A to the upper part Q3 on the other side of the heat insulating door 8A.
In addition, although the aspect in which the handle is not provided in the heat insulating door 8A has been described as an example here, the present invention is not limited thereto. For example, an aspect in which the handle is provided at a position corresponding to the lower portion Q1 may be used. . Moreover, the aspect which opens and closes with a button etc. without providing a handle in the heat insulation door 8A may be sufficient. Even in these modes, the region corresponding to the lower portion Q1 is held and the heat insulating door 8A is opened and closed.

FIG. 3 is a front view of the heat insulating door 8A of the refrigerator 1 according to the first embodiment. FIG. 4 is a view of the heat insulating door 8A as viewed from the side. FIG. 5 is a cross-sectional view taken along the dotted line XX shown in FIGS. 2 and 3. 6 is a cross-sectional view taken along the dotted line ZZ shown in FIGS. 2 and 4.
As shown in FIG. 4, the heat insulating door 8 </ b> A is provided with a magnet gasket 22 that is attached to the inner plate 14 and prevents cold air in the refrigerator compartment 3 from leaking.

  The glass plate 10 is a rectangular plate whose longitudinal direction is the vertical direction. The glass plate 10 and the inner plate 14 have a side cap 13a fitted at one end and a side cap 13b fitted at the other end. An upper surface cap 11 is fitted on the upper ends of the glass plate 10 and the inner plate 14, and a lower surface cap 12 is fitted on the lower ends. In addition, in this Embodiment 1, although an example is demonstrated about the aspect by which the glass plate 10 was provided in 8 A of heat insulation doors, you may comprise with resin etc., without being limited to glass.

  The inner plate 14 is provided at a position opposed to the glass plate 10 on the refrigerator compartment 3 (storage chamber) side than the glass plate 10, and closes the opening of the refrigerator compartment 3 (storage chamber) when the heat insulating door 8A is closed. Is. The inner plate 14 is made of resin.

  The pair of side caps 13 are attached to the side end portion of the glass plate 10 and the side end portion of the inner plate 14 facing the side end portion of the glass plate 10, and a separation suppressing portion 18 is provided. The peeling suppression part 18 is provided in at least one of the upper part and the lower part of the side cap 13b. In the first embodiment, an aspect provided in both the upper part and the lower part of the side cap 13b will be described. The upper peeling suppressing portion 18 is provided, for example, at a position of about 50 mm from the upper end surface of the side cap 13b. Moreover, the lower peeling suppression part 18 is provided in the position of about 50 mm from the lower end surface of the side cap 13b, for example. The pair of side caps 13 are made of resin.

The side cap 13b is formed so as to extend in the vertical direction, and is formed so that the front end side protrudes to the glass plate 10 side in a state where the plate-like portion 13A provided with the peeling suppressing portion 18 and the heat insulating door 8A are closed. The first edge portion 13B1 extending in the up-down direction and the second edge portion 13B2 extending in the up-down direction formed so that the rear end side protrudes toward the inner plate 14 side when the heat insulating door 8A is closed. It is what you are doing.
The side cap 13a also has a configuration similar to that of the side cap 13b. That is, the side cap 13a also has a plate-like portion, a first edge portion 13B1, and a second edge portion 13B2.

  As for the peeling suppression part 18, one end side and the other end side are connected to the inner surface of the plate-shaped part 13A of the side cap 13b which comprises a part of frame, The intermediate part between this one end side and the other end side is plate-shaped. It is separated from the inner surface of the portion 13A. More specifically, the peeling suppressing portion 18 is connected to the plate-like portion 13A of the side cap 13b, and the first protruding portion 181 and the second protruding portion 183 protruding toward the closed space inside the frame body of the heat insulating door 8A, One end side is connected to the first projecting portion 181, and the other end side has a connecting portion 182 connected to the second projecting portion 183.

  The peeling suppressing portion 18 is formed so that the first protruding portion 181 and the second protruding portion 183 extend in parallel in the horizontal direction, and the connecting portion 182 is connected so as to be orthogonal to the first protruding portion 181 and the second protruding portion 183. Has been. That is, the peeling suppression part 18 is formed in a U-shape in a horizontal sectional view. Therefore, in the peeling suppressing portion 18, the connecting portion 182 is separated from the plate-like portion 13A by a preset interval. For this reason, the clearance gap S is formed between the peeling suppression part 18 and the plate-shaped part 13A. The foam heat insulating material 15 is filled in the space in the frame body including the gap S between the peeling suppressing portion 18 and the plate-like portion 13A.

  Here, the size of the opening surface of the gap S is preferably equal to or larger than the size of about 4 to 5 mm × 4 to 5 mm, for example. That is, it is preferable that the facing distance between the first protruding portion 181 and the second protruding portion 183 is larger than 4 to 5 mm, and the facing distance between the plate-like portion 13A and the connecting portion 182 is larger than 4 to 5 mm. If it is smaller than this, the foamed heat insulating material 15 may hardly flow into the gap S or may not flow. If the foamed heat insulating material 15 does not flow into the gap S, the foamed heat insulating material 15 and the peeling suppressing portion 18 are less likely to be caught. For this reason, since the effect which suppresses peeling which is mentioned later will become small, the magnitude | size of the opening surface of the clearance gap S is set as mentioned above.

  The upper surface cap 11, the lower surface cap 12, the pair of side surface caps 13, the inner plate 14, and the peeling suppressing portion 18 are made of resin.

  FIG. 7A is a perspective view of side cap 13 included in heat insulating door 8A of refrigerator 1 according to the first embodiment. FIG. 7B is an explanatory diagram of a mold used when the side cap 13 is formed. The side cap 13 is a structure corresponding to a side part.

  The side cap 13b is formed integrally with a plate-like portion 13A, a first edge portion 13B1, and a second edge portion 13B2. Moreover, the 1st protrusion part 181, the 2nd protrusion part 183, and the connection part 182 are integrally formed. And the side cap 13b and the peeling suppression part 18 are integrally formed. Here, a structure in which the side cap 13b and the peeling suppressing portion 18 can be formed integrally will be described.

The peeling suppressing part 18 is provided in the plate-like part 13A so that the opening surface of the gap S between the plate-like part 13A is parallel to the horizontal direction. In other words, the opening surface is orthogonal to the vertical direction.
When the side cap 13b and the peeling suppressing portion 18 are integrally manufactured, a mold slide core P is disposed at a position corresponding to the gap S so that the resin does not flow into the gap S. In this state, resin is injected into the mold.

  Here, the side cap 13b has a first edge 13B1 and a second edge 13B2. For this reason, after inject | pouring resin into a metal mold | die, the slide core P mentioned above cannot escape to the 1st edge part 13B1 or the 2nd edge part 13B2 side. Therefore, the slide core P moves parallel to the longitudinal direction of the plate-like portion 13A and escapes by making the opening surface of the gap S between the separation suppressing portion 18 and the plate-like portion 13A parallel to the horizontal plane. be able to.

[Effects of Refrigerator 1 according to Embodiment 1]
In the refrigerator 1 according to the first embodiment, the peeling suppressing portion 18 is provided on the side cap 13b of the heat insulating door 8A. And since the foaming heat insulation material 15 is filled also in this peeling suppression part 18, when the heat insulation door 8A is opened and closed, it can suppress that the frame of the heat insulation door 8A deform | transforms. That is, even if the heat insulating door 8 </ b> A is opened and closed, the frame of the heat insulating door 8 </ b> A is deformed, and even if this frame acts to peel from the foam heat insulating material 15, the separation suppressing portion 18 is caught on the foam heat insulating material 15. Since it is acting like this, peeling with this frame and the foam heat insulating material 15 can be suppressed. Thereby, the refrigerator 1 which concerns on this Embodiment 1 can suppress that heat insulation performance will fall by aged deterioration by opening and closing of the heat insulation door 8A.

  Since the refrigerator 1 according to the first embodiment includes the peeling prevention unit 18, it has an effect of preventing cold air leakage and dew condensation due to deterioration over time and improving the open / close life of the heat insulating door 8A.

  Since the refrigerator 1 which concerns on this Embodiment 1 can suppress peeling with the frame of the heat insulation door 8A, and the foam heat insulating material 15, the intensity | strength of the heat insulation door 8A has improved to that extent.

  The peeling prevention part 18 of the refrigerator 1 according to the first embodiment has a first protrusion 181, a second protrusion 183, and a connection part 182, and is a foam heat insulating material between the plate-like part 13 </ b> A of the side cap 13. 15 has a formation in which a gap S filled with 15 is formed. In this way, even if a load is applied to the frame of the heat insulating door 8A in any of the upper, lower, left, and right directions, the peeling prevention portion 18 forms a cylindrical structure together with the plate-like portion 13A. Deformation can be effectively suppressed even in deformation.

  In the refrigerator 1 according to the first embodiment, the front surface portion of the heat insulating door 8A is the glass plate 10, and the back surface portion of the heat insulating door 8A is the inner plate 14, which are separate bodies. Thus, when the front surface portion and the back surface portion of the heat insulating door 8A are separate bodies, deformation when the heat insulating door 8A is opened and closed is easily generated. However, even in the refrigerator 1 having such an aspect, since the peeling suppressing portion 18 is provided, peeling between the frame body of the heat insulating door 8A and the foam heat insulating material 15 can be suppressed. In addition, you may provide the peeling suppression part 18 in the refrigerator with which the front-surface part and back surface part of 8 A of heat insulation doors are integral.

  In the refrigerator 1 which concerns on this Embodiment 1, the aspect which provided the peeling suppression part 18 one each in both the upper part and lower part of the side cap 13b was demonstrated. Here, as described in the explanation of FIG. 2B, the region T1 is a place where the heat insulating door 8A is likely to be deformed. Then, if the peeling suppression part 18 is provided in the part which comes on the area | region T1 among the side caps 13, peeling with the frame of the heat insulation door 8A and the foam heat insulating material 15 can be suppressed effectively. That is, it is good to provide the peeling suppression part 18 in the lower part Q2 of the side cap 13a, and to provide the peeling suppression part 18 in the upper part Q3 of the side cap 13b.

  In the first embodiment, the side cap 13b and the peeling suppressing portion 18 are described as being integrally formed. However, the present invention is not limited to this, and a separate body may be used. Moreover, you may form the peeling suppression part 18 so that the opening surface of the clearance gap S may face 1st edge part 13B1 and 2nd edge part 13B2. The effect similar to the refrigerator which concerns on this Embodiment 1 can be acquired also by this.

The peeling suppression part 18 may be formed so that the inner surface and the outer surface thereof have a large contact area with the foam heat insulating material 15. For example, a plurality of irregularities may be formed on the inner surface and the outer surface of the peeling suppressing portion 18. By forming irregularities on the surface of the peeling prevention part 18, the contact surface area between the peeling prevention part 18 and the foam heat insulating material 15 increases, and the adhesion between the peeling prevention part 18 and the foam heat insulating material 15 can be improved. . Thereby, the improvement of the effect which suppresses peeling with a frame and the foam heat insulating material 15 can be aimed at.
In addition, you may make it form an unevenness | corrugation not in the whole surface of the peeling suppression part 18, but in one part surface. For example, the same effect can be obtained by forming irregularities on the outer surface and not forming irregularities on the inner surface that is the surface on the gap S side. In addition, the first protrusion 181 and the second protrusion 183 may be uneven, and the connection 182 may not be uneven. Also by this, the improvement of the effect which suppresses peeling with a frame and the foam heat insulating material 15 can be aimed at.

In this Embodiment 1, the case where the front part of the heat insulation door 8A was the glass plate 10 was demonstrated. Thus, if the heat insulation door 8A is made into the glass plate 10 in consideration of designability etc., since the inner plate 14 is comprised with resin etc., the front part and back part of the heat insulation door 8A can be comprised integrally. become unable. If the front portion and the rear portion are separated, the frame of the heat insulating door 8A is likely to be deformed due to deterioration over time, and therefore, the frame of the heat insulating door 8A and the foamed heat insulating material 15 are likely to be separated by opening and closing the heat insulating door 8A. Become.
Here, in the heat-insulating door 8A that is a rotary type and whose longitudinal direction is the vertical direction, deformation of the portion indicated by the region T1 in FIG. 2B is likely to occur. Then, as described above, in the heat insulating door 8A in which the front surface portion and the back surface portion are configured separately, the deformation due to aging of the region T1 is further increased.
However, in the refrigerator 1 according to the first embodiment, the front surface portion of the heat insulating door 8A is configured by the glass plate 10 and the front surface portion and the back surface portion are separated from each other, but the separation suppressing portion 18 is provided. Therefore, peeling between the frame of the heat insulating door 8A and the foam heat insulating material 15 can be suppressed.

  In addition, it cannot be overemphasized that the peeling suppression part 18 demonstrated with the refrigerator 1 which concerns on this Embodiment 1 may be provided in the heat insulation door 8B.

The end side has a connection part 182 </ b> B connected to the other end side of the second projecting part 183. And the connection part 182B is formed so that it may protrude in the opposite side to the plate-shaped part 13A side so that the clearance gap S may become narrow when it sees in horizontal cross section.

  Further, as shown in FIG. 8C, the peeling suppressing portion 18 may have a triangular shape in a horizontal sectional view. The peeling suppressing portion 18C is not formed with a configuration corresponding to the connecting portion 182. The peeling suppressing portion 18C includes a first protrusion 181 and a second protrusion 183C having one end connected to the plate-like portion 13A and the other end connected to the other end of the first protrusion 181.
