  Also, in this embodiment, from the viewpoint of maintaining heat insulation properties, a part of the recess is provided, but by forming a recess from the top to the bottom, a handle portion that can be used anywhere is provided. Also good.

  As shown in FIGS. 1 and 3, the front and rear doors 4a and 4b of the refrigerator 1 are formed with a maintenance recess 7 continuous from the top to the bottom. With reference to FIG. The relationship with the second handle 10 will be described. 4 is a partial enlarged cross-sectional view of the open / close door of the refrigerator according to Embodiment 1 of the present invention, in which (a) is a cross-sectional view taken along line AA, and (b) is a cross-sectional view taken along line BB. is there.

  As shown in FIG. 4 (a), the care recess 7 is provided between the glass plates 5a and 6a, and the position of the cross section along line AA in FIG. Not provided. On the other hand, as shown in FIG. 4 (b), a first handle portion 9a is provided at a position where the cross section along the line B-B is low. The second handle portion 10a is formed by a recess facing toward the first handle portion 9a. In addition, although it has the 2nd handle part 10b of the same structure also at the door 4b side, description is abbreviate | omitted.

  The user can open and close the open / close door 4a by placing his / her left hand on the handle 11 on the glass plate 5a side of the first handle portion 9a, and insert the right hand into the care recess 7 and the second handle portion. The door 4 can be opened and closed by placing a hand on the handle 12 on the glass plate 5a side of 10a. The care recess 7 has a rounded shape facing the glass plate 5a. By using this shape, finger insertion can be smoothly guided.

  One of the features of the present invention is that a column 13 is provided between the first handle portion 9a and the second handle portion 10a. And the glass material 5a which is a translucent material is provided in the front surface of the 1st handle part 9a, the 2nd handle part 10a, and the support | pillar part 13 in these front surfaces. In the present embodiment, the glass material 5a and the door 4a are bonded by first temporarily fixing the handle 11 and 12 which are a part of the frame 14 of the door 4a with an adhesive member such as a double-sided tape. A foamed heat insulating material is injected into the open / close door 4a and filled into the support column 13, and the foamed heat insulating material and the glass material 5a are bonded to each other to be permanently fixed. Since the glass material 5a can be temporarily fixed by having the grips 11 and 12 which are the frame bodies 14, the opening / closing door 4a and the glass material 5a are perfectly fitted with reduced distortion even when foamed heat insulating material is injected. Can be pasted. Further, since the urethane foam heat insulating material and the glass material 5a are bonded to each other on the surface, there is an effect of absorbing an impact, and even if the glass is broken, scattering of glass fragments can be suppressed.

  In addition, the column portion 13 is provided between the first handle portion 9a and the second handle portion 10a, and the glass plate 5a is provided on the front surface thereof, so that, for example, the door is opened using the second handle portion 10a. Even when a force is applied during opening and closing, the distance between the fulcrum and the force point is shorter than when a supporting column is provided on the side surface (for example, FIG. 8), so that the applied force can be reduced. Further, by providing the first handle portion 9a, the action of the force applied to the second handle portion 10a can be dispersed. The displacement and deflection of the surface handle frame and the separate material due to bending stress and shearing force on the glass plate can be reduced. Therefore, since a thinner material or a material with less rigidity can be used, it is possible to provide a highly convenient handle portion in which the vertical dimension of the handle is increased and a finger can be easily inserted.

  Moreover, according to the said structure, the 1st handle part 9a formed in the recessed part is provided in the side surface opposite to the rotating shaft R of the door 4, and the maintenance formed in the front surface of the door 4 by the recessed part is provided. Since the concave portion 7 is formed and communicated with the care concave portion 7, and the second handle portion 10a formed by the concave portion is formed on the opposite side of the hinge portion 5 of the door 4a, the door is opened from both the left and right sides. Since the handle is provided by the concave portions on the front surface and the side surface, there is no thing protruding forward, and space can be saved when arranging.

  In recent years, from the viewpoint of universal design, it has been demanded that any person can use it fairly and has a higher degree of freedom in use. By providing the first handle portion 9a and the second handle portion 10a, left and right It can be accessed from both, and can provide a refrigerator according to the characteristics of each hand. In addition, as a handle that can be accessed from both the left and right, there is a type provided with a handle that is attached to the front surface of the refrigerator door. However, compared with this, this application can also reduce work man-hours and the number of parts in a manufacturing process, and can suppress cost. In addition, if the handle protrudes, additional packaging is required at that location, and the vertical dimension when packing is increased. On the other hand, as shown in this embodiment, the front surface can be made almost flat, special packaging is not required, the packaging cost can be reduced, and the vertical dimension can be reduced accordingly, so storage・ The number of transported vehicles can be increased.

  FIG. 5 is a partial enlarged cross-sectional view taken along line BB of the modified example of the refrigerator according to the first embodiment of the present invention. In this modification, the lateral width L2 of the second handle 10a is longer than the lateral width L1 of the first handle 9a. For example, as an example of the dimensions, the lateral width L1 can be 20 mm to 30 mm, and the lateral width L2 can be 30 mm to 40 mm. This is because L1 is designed so that fingers can be inserted to the distal interphalangeal joint called the first joint, and L2 is designed to insert the finger to the proximal interphalangeal joint called the second joint. Designed to be insertable.

  Normally, the revolving door of the refrigerator is provided with a packing containing a resin magnet around the back surface, and is in close contact with the refrigerator body so as not to open and close carelessly. When opening and closing the revolving door, not only the force to rotate the door but also the force to peel off this packing from the refrigerator body is necessary, so the inner side closer to the hinge part than the side requires more force to open and close . Accordingly, by increasing the lateral width L2 of the second handle portion 10, it is possible to put a finger deeper and to apply a force for opening and closing the door 4 more.

  Another feature of the present invention is the provision of a finger hooking portion 20, which will be described below with reference to FIG. FIG. 6 is a partially enlarged view of a door provided with a finger hook portion of the refrigerator according to the embodiment of the present invention.

  In recent years, products with glass material on the surface of refrigerator doors have been commercialized and can be harmonized with the interior of the kitchen, and the surface is formed with a glossy surface peculiar to glass material, and it has excellent luxury design. It is a refrigerator. However, when dirt such as fingerprints adheres to the front surface of the door, there is a problem that these dirts become more conspicuous by having a glossy surface peculiar to a glass material.

  In addition, when opening and closing a door having a handle portion provided with a concave portion on the top and bottom as in the present invention, the little finger from the index finger puts a hand into the concave portion, but usually the thumb is free to go outside. As it works, there is a problem that dirt is attached by touching and touching the front surface of the glass with the thumb when opening and closing.

  Therefore, in the present invention, the finger grip portion 20 having a surface inclined toward the first handle portion 9a is provided on the second handle portion 10a side of the glass material 5a. In the present embodiment, the finger-hanging portion 20 is configured to be integrally formed with the frame body 11, but another member may be provided.

  With such a configuration, when a hand is put into the second handle portion 10a, it is possible to prevent a dirt such as a fingerprint from adhering to the surface of the glass plate 5a by providing a place where the thumb can be freely attached. Furthermore, by providing the finger hooking portion 20 whose surface is inclined in the direction of the first handle portion 9a, since the inclined surface is provided opposite to the direction of movement during the opening operation M, the thumb can be applied more. The shape is easy to apply power.

  As another modified example, as shown in (b), an open / close door 4a having a finger hook portion 20 having a surface inclined toward the hand hook recess 7 is also conceivable. This shape takes into consideration the operating range of the thumb, that is, the inclined surface is provided in the direction in which the thumb is extended.

  Moreover, as shown in (c), the finger-hook part 20 which has a concave surface as shown in FIG. With such a configuration, it is easy to apply a force during the opening and closing operation, and it is easy to apply force. Since the inclined surface is provided in the direction in which the thumb is extended, the shape is easier to attach.

In addition, about this modification, the finger hook part 20 provided only in the 2nd handle part 10a side was demonstrated. This is because when opening and closing the revolving door, not only the force to rotate the door but also the force to peel the packing containing the resin magnet from the refrigerator body is required, so the first handle portion 9a on the side surface The inner second handle portion 10b closer to the rotation axis R requires a larger force for opening and closing. Therefore, a configuration is adopted in which a thumb is provided on the second handle portion 10a side where the glass plate 5a is easily attached by applying force. However, as a matter of course, a similar finger hook portion may be provided on the first handle portion 9a side.
