DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator provided with a door for opening and closing a storage room so that the storage room can be opened and closed.

[0002]

2. Description of the Related Art Conventionally, this kind of household refrigerator is constituted by a heat insulating box body in which a foam heat insulating material such as polyurethane foam is filled between a steel sheet outer box and a hard resin inner box by an in-situ foaming method. By partitioning the inside of the heat insulating box, a freezing room cooled to a freezing temperature such as -20 ° C. or +
A refrigeration room is maintained at a refrigeration temperature such as 5 ° C., and a vegetable room for storing food such as vegetables that is difficult to dry is formed.

The front opening of the refrigerator compartment is openably and closably closed by a pivotable door, and the front openings of the freezer compartment and the vegetable compartment are openably closable by a drawer door.
A handle is attached to the front surface of the pivotable door and the drawer door. Here, as a conventional example, a handle member 101 attached to a pivotable door will be described with reference to FIGS.

FIG. 7 is a side view of a conventional handle member 101, FIG. 8 is a front view of the handle member 101, and FIG.
FIG. 3 shows a cross-sectional view taken along line B. The conventional handle member 101 is
It is formed so as to be longer in the vertical direction by injection molding a hard synthetic resin, and is attached by being engaged with a concave portion formed on the front side of a pivotable door (not shown).

[0005] The handle member 101 comprises a main body 102 and a cover 103. The main body 102 is connected to a connection portion 10 which is engaged with and connected to a concave portion formed in the door.
4 and a handle 105 for applying fingers when the door is opened and closed.
It consists of. The connecting portion 104 is curved at a predetermined curvature so as to become lower from the left side to the right end, and is formed into a curved shape in which the left side tapers from the center upward and downward, in particular. Also,
At the left and right edges of the connecting portion 104, grooves 106 and 107 having a substantially U-shaped cross section for engaging with a steel plate outer plate edge forming a recess of the door are formed.

On the other hand, the handle portion 105 is formed to have substantially the same vertical dimension as the connecting portion 104 and to have substantially the same width as the upper and lower ends of the connecting portion 104. As shown in FIG. 7, the handle portion 105 is formed to be curved at a predetermined curvature in the front direction from the upper end to the lower end such that the center portion projects to the front side most. The upper end and the lower end of the handhold 105 are continuous with the upper end and the lower end of the connecting part 104, so that the main body 102 has a central part between the connecting part 104 and the handhold 105 for finger insertion penetrating in the left-right direction. Opening 108
Are formed.

Further, as shown in FIG. 9, the cross section of the handle portion 105 has an inclined portion 109 inclined from the left end toward the back.
And an inclined portion 110 that is inclined from the end of the inclined portion 109 toward the front side and reaches the right end. Furthermore, fitting portions 111 and 11 for fitting the cover 103 are provided on both side ends of the handle portion 105.
2 are formed.

The cover 103 is made of the same hard synthetic resin as the main body 102, and is formed to have substantially the same size as the handle 105 of the main body 102. The cover 103 has a U-shaped cross section and is curved so as to correspond to the handle 105. Further, a fitting portion 113 for fitting with the fitted portions 111 and 112 of the handle portion 105 is provided inside the open end of the U-shape.
114 are formed.

The assembling procedure of the handle member 101 is as follows. After the grooves 106 and 107 of the connecting portion 104 of the main body 102 are attached to the outer plate edge forming the concave portion of the door (not shown),
3 with the opening side facing the handle 105, and
The fitting is completed by fitting the fitting portions 113 and 114 of the cover 103 to the fitting portions 111 and 112 of the cover 05. Thereby, a space is formed inside the handle portion 105 and the cover 103, and their outer shapes have a thickness that is easy to grasp.

[0010]

As described above, the outside diameter of the handle 105 of the handle member 101 must be a predetermined thickness or thickness in order to make it easy to grasp. On the other hand, if the inside is entirely filled with the synthetic resin, distortion occurs due to sink marks. Therefore, as described above, the main body 1
02 has a two-part structure of a handle 105 and a cover 103.

However, in such a configuration, the handle 10
5 each time a force is applied,
1 and 112 are fitting portions 113 and 114 of the cover 103
A squeak sound is generated due to rubbing with the like.

Further, in this structure, the handle member 101 is composed of two parts, the main body 102 and the cover 103, so that the number of parts is increased, the cost is increased, and the assembling work of the handle member 101 is complicated. There was a problem.

The present invention has been made to solve the above-mentioned conventional technical problems, and can improve the workability of assembling a handle member of a door and reduce the cost associated with the reduction in the number of parts. It is intended to provide a refrigerator that can be designed.

[0014]

In the refrigerator of the present invention, a handle portion of a handle member attached to a door is formed by hollow molding.

A refrigerator according to a second aspect of the present invention is characterized in that the handle member is a grip-type handle member.

A refrigerator according to a third aspect of the present invention is characterized in that the handle member is a hook-type handle member.

According to the present invention, the handle portion of the handle member attached to the refrigerator door is formed by hollow molding. In the case of the second aspect, the outer dimensions are relatively large in order to make it easy to grasp with fingers. Alternatively, in the case of claim 3, it is possible to constitute a handle part having a relatively thick outer dimension for hooking a finger with one component. As a result, it is possible to reduce the number of parts and the number of assembling steps as compared with the conventional handle member in which the handle portion is composed of a plurality of parts, improve the strength, and generate squeaking noise and the like. Can be prevented beforehand.
