doors

8 and 9, respectively, and are preferably steel plates. This steel plate uses, for example, a high-gloss steel plate or a dark-colored steel plate in order to improve the aesthetic appearance of the front side of the refrigerator.

FIG. 3 is an enlarged cross-sectional view showing a structural example of the region portion R of the door 8 and the door 9 shown in FIG. This region portion R includes the lower part of the door 8 and the upper part of the door 9. 3 shows a cap 11 on the lower side of the door 8, a face material 12 of the door 8, a cap 13 on the upper side of the door 9, a face material 15 of the door 9, and the like. The lower cap 11 and the upper cap 13 are both made of plastic, for example, but may be made of metal.

As shown in FIG. 2, a foam heat insulating material 17 such as a urethane foam material is filled between the face material 12 of the door 8, the upper and

lower caps

10 and 11, and the inner plate 16 by foaming. Similarly, a foam heat insulating material 19 such as urethane foam is filled between the face material 15 of the door 9, the upper and

lower caps

13 and 14, and the inner plate 18 by foaming.

First, an example of the structure of the cap 11 on the lower side of the door 8 will be described with reference to FIG.

The cap 11 of the door 8 has a handle part 20, a front rib 21, a gasket receiving part 22, and a flat part 24. The cap 13 includes a handle portion 30, a front rib 31, a gasket receiving portion 32, and a flat portion 34.

In the example of the refrigerator 1 shown in FIG. 1, as indicated by broken lines, the

handle portions

20, 30 have a predetermined length along the X direction, which is the left-right direction of the refrigerator body 2. It is provided in a sufficient length that can be inserted into the

parts

20 and 30 and hung.

The Z direction shown in FIG. 1 is the vertical direction of the refrigerator 1, and the Y direction is the depth direction of the refrigerator 1. The X, Y, and Z directions are orthogonal. The

handle portions

20 and 30 are portions for the user to insert fingers to open and close the

doors

8 and 9, respectively, but can be referred to as handles.

The handle portion 20 of the cap 11 is formed at a position between a rib 21 positioned at the foremost side and a flat portion 24 positioned at the rear side of the rib 21. Handle 20, in the inner plate member 12 of a lower surface of the door 8 Moreover door 8, is formed in an inverted concave shape so as to protrude upward along the Z ¹ direction.

The handle portion 20 has a C-shaped cross section that is oriented substantially sideways so that the user's fingers can be easily put on. The handle portion 20 opens and closes the front opening 6P by operating the door 8 when the user puts his finger upward.

Rib 21 is formed continuously to the front portion 20A of the handle portion 20 are upwardly formed along the Z ¹ direction. A face material mounting groove 23 is formed between the inner surface 21 A of the rib 21 and the front portion 20 A of the handle portion 20. Z ¹ direction height of the rib 21 is smaller than the height H1 of the handle portion 20. Thereby, the rib 21 can be made as inconspicuous as possible on the surface side of the face material 12.

A flat portion 24 is formed between the rear portion 20B of the handle portion 20 and the gasket receiving portion 22. The gasket receiving portion 22 fixes the rear part by inserting the gasket 25 of the rear part.

As shown in FIG. 3, the lower end portion of the face material 12 is held or fixed to the cap 11 by being fitted into the face material attachment groove 23. The inner surface 21A of the rib 21 and the front portion 20A of the handle portion 20 are in contact with the front surface and the rear surface of the face member 12, respectively. Thereby, the lower end portion of the face material 12 can be reliably held or fixed so as to be sandwiched between the inner surface 21A of the rib 21 of the cap 11 and the front side portion 20A of the handle portion 20.

For this reason, as shown in FIG. 2, even when the foam heat insulating material 17 is filled between the face material 12 of the door 8, the upper and

lower caps

10, 11 and the inner plate 16, the foam heat insulating material 17 is foamed. The appearance distortion of the face material 12 can be suppressed. Therefore, even if the face material 12 such as a thick-colored or high-gloss steel plate is used as the front material of the door 8, the appearance distortion of the face material 12 can be suppressed.

When the foam heat insulating material 17 is filled in the door 8 having such a configuration by foaming, the foam heat insulating material 17 is formed on the inner surface of the lower end portion of the face material 12 and the upper surface side of the cap 11. The interior of the space of the door 8 can be filled without any gaps. For this reason, since a gap is not easily generated inside the door 8, the heat insulation of the door 8 can be improved.

Although the lower end portion of the face material 12 is fitted in the face material attachment groove 23, it is assumed that there is a gap between the back side of the face material 12 and the front portion 20A of the handle portion 20. However, since the foam heat insulating material 17 is filled in the gap, the lower end portion of the face material 12 can be reliably fixed.

Next, an example of the structure of the cap 13 on the upper side of the door 9 will be described with reference to FIG.

Handle portion 30 of the cap 13 of door 9 is, the handle portion 30 is formed at a position between the rib 31 and the flat portion 34, inside of the door 9, so as to project downward along the Z ² direction It is formed in a concave shape. The handle 30 has a substantially J-shaped cross section. The handle 30 is provided for the user of the refrigerator to open and close the front opening 7 P by operating the door 9 by putting their fingers downward.

Rib 31 is formed continuously to the front portion 30A of the handle portion 30 is formed downward along the Z ² direction. A face material mounting groove 33 is formed between the inner surface 31 A of the rib 31 and the front portion 30 A of the handle portion 30.

A flat portion 34 is formed between the rear portion 30 B of the handle portion 30 and the gasket receiving portion 32. The gasket receiving portion 32 fixes the rear part by inserting the gasket 35 of the rear part.

The upper end portion of the face material 15 is held or fixed to the cap 13 by being fitted into the face material attachment groove 33. The inner surface 31A of the rib 31 and the front portion 30A of the handle portion 30 are in contact with the front surface and the rear surface of the face material 15, respectively.

Thus, the upper end portion of the face material 15 can be securely held or fixed with respect to the cap 13 so as to be sandwiched between the inner surface 31A of the rib 31 and the front portion 30A of the handle portion 30. For this reason, when the foaming heat insulating material 19 is filled and foamed between the face material 15 of the door 9, the upper and

lower caps

13 and 14, and the inner plate, the appearance distortion of the face material 15 can be suppressed. Therefore, even if a face material 15 such as a high-gloss or thick steel plate is used as the front material of the door 9, the appearance distortion of the face material 15 can be suppressed.

When the foam heat insulating material 19 is filled in the door 9 having such a configuration, the foam heat insulating material 19 does not cause a gap to the inner surface of the face material 15 and every corner on the lower surface side of the cap 13, Can be filled. For this reason, since a clearance is hardly generated inside the door 9, the heat insulation of the door 9 can be improved.

Although the upper end portion of the face material 15 is fitted in the face material attaching groove 33, even if a gap is generated between the inner surface side of the face material 15 and the front side portion 30A of the handle portion 30, this gap Since the foam heat insulating material 19 is filled, the upper end portion of the face material 15 can be reliably fixed.

As shown in FIG. 3, the dimension between the upper end part and the lower end part of the handle part 20 on the door 8 side, that is, the height dimension of the handle part 20 is represented by H1. The dimension between the upper end part and the lower end part of the handle part 30 on the door 9 side, that is, the height dimension of the handle part 30 is represented by H2. The dimension of the space formed between the lower end portion of the handle portion 20 and the front side portion 30A of the handle portion 30 is represented by A. The dimension between the front part 30A and the rear part 30B of the handle part 30 is represented by B. Preferably, the height dimensions H1 and H2 of the handle portion 20 are set to be smaller than the empty dimension A and smaller than the dimension B. Thereby, since the empty dimension A and the dimension B are set large, the user can freely select a finger regardless of the handle part 20 on the door 8 side or the handle part 30 on the door 9 side. Then, the door 8 or the door 9 can be opened.

Further, as shown in FIG. 3, the position of the height dimension H 1 of the handle portion 20 that represents the depth of the recess of the handle portion 20 is lower than the center position L of the gasket 25. Since the position of the height dimension H1 of the handle part 20 is lower than the center position L of the gasket 25, the height dimension H1 of the handle part 20 corresponds to the length of the first joint of the user's finger. Thus, the user can easily open and close the door 8 by putting the first joint of the finger into the handle portion 20.

In 1st Embodiment shown in FIG. 1, the handle part 20 of the door 8 and the handle part 30 of the door 9 use, for example along the X direction (full width direction of the doors 8 and 9) which is the left-right direction of the refrigerator main body 2. The finger is provided long enough to be inserted into the

handle parts

20 and 30 and hung.

Since the handle portion 20 of the door 8 and the handle portion 30 of the door 9 are provided, even if the foamed heat insulating material 17 is filled in the door 8, the appearance distortion of the face material 12 occurs on the front side of the door 8. Even if the foamed heat insulating material 19 is filled in the door 9, it is possible to suppress the appearance distortion of the face material 15 on the front side of the door 9.

(Description of comparative example)
Here, with reference to the comparative example of the refrigerator which is outside the scope of the present invention shown in FIG. 4, the shape of the cap 120 and the like having the handle portion of the comparative example will be described. FIG. 4 shows a cap 120 having a handle portion 123 and another cap 220 in the refrigerator of the comparative example.

In the comparative example shown in FIG. 4, the surface of the face material 112 of the upper door 108 is held against the rib 121 of the cap 120.

The rib 121 has a large height in the Z direction, and the protrusion 122 has a large height in the Z direction. The positions of the protrusion 122 and the handle portion 123 are separated from the position of the rib 121.

For this reason, since the foam heat insulating material 130 is difficult to enter the gap between the back surface of the face material 112 and the protrusion 122 and the gap between the protrusion 122 and the handle portion 123, the bonding area of the foam heat insulating material 130 is reduced, and The lower end cannot be securely fixed to the cap 120. The presence of the protrusion 122 interferes with the filling of the foam heat insulating material 130. For this reason, it is not possible to suppress the appearance distortion of the face material 112 when the foam heat insulating material 130 is foamed.

Further, the surface of the face material 115 of the lower door 109 is held against the rib 221 of the cap 220. The cap 220 is provided with a protrusion 222 in the Z direction on the inner side of the rib 221. The height of the rib 221 in the Z direction is large, and the height of the protrusion 222 in the Z direction is also large.

For this reason, since the foam heat insulating material 230 is difficult to enter the gap between the back surface of the face material 115 and the protrusion 222, the adhesive area of the foam heat insulating material 230 is small, and the upper end portion of the face material 115 is securely attached to the cap 220. It cannot be fixed. The presence of the protrusion 222 interferes with the filling of the foam heat insulating material 230. For this reason, it is not possible to suppress the appearance distortion of the face material 115 when the foam heat insulating material 230 is foamed.
