DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a door structure in a storage such as a refrigerator provided with a drawer door.

[0002]

2. Description of the Related Art A door structure of a conventional refrigerator will be described with reference to FIG. In FIG. 13, 1 is a refrigerator main body,
Reference numerals 2 and 3 denote an upper drawer door and a lower drawer door which are arranged in two stages at the front opening portion of the refrigerator main body 1, and 4 denotes a pair of left and right screws which are screwed to the rear surface of the upper drawer door 2 and arranged in the front-rear direction. The frame 5 is a pair of left and right frames screwed to the rear surface of the lower drawer door 3 and arranged in the front-rear direction, 6, 7 are storage cases fitted respectively between the frames 4 and 5, and 8 is the refrigerator body 1. Closing members 9 and 10 are provided on the front opening portions in the left-right direction, and are gaskets attached to the drawer doors 2 and 3 and brought into close contact with the closing member 8 when the drawer doors 2 and 3 are closed.

[0003] Each of the frames 4 and 5 has a pair of left and right rollers 11, which are attached to the inner front portion of the refrigerator body 1.
12 and is slidable in the front-rear direction of the refrigerator body 1, and a pair of left and right rails 13, disposed on the inner surface of the refrigerator body 1 in the front-rear direction,
Rollers 15 and 16 which are rotatably fitted to the roller 14 are attached. Further, as shown in FIG. 14, inclined portions 4a and 5a which are inclined upward and forward are formed at the lower front portions of the frames 4 and 5, respectively.

Thus, when the upper and lower drawer doors 2 and 3 are pulled out to the front, the frames 4 and 5 and the storage cases 6 and 7 are pulled out.
Are moved forward integrally, and the inclined portions 4 of the frames 4 and 5 are moved.
The upper and lower drawer doors 2 and 3 are opened while being shifted upward by a distance A shown in FIG. 15 (while being lifted obliquely upward) by sliding the rollers a and 5a on the rollers 11 and 12. Further, when the upper and lower drawer doors 2 and 3 are pushed in, the frames 4 and 5 and the storage cases 6 and 7 are integrally moved rearward, and just before closing, the inclined portions 4a and 5a
12 slides on the upper and lower drawer doors 2,
3 returns to its original position (moving diagonally downward)
It closes automatically and automatically (the self-closing force works). With such a structure, the upper and lower drawer doors 2, 3
However, it is possible to prevent the cool air from escaping from the gap between the upper and lower drawer doors 2 and 3 and the refrigerator body 1 without closing the door slightly and opening it.

[0005]

When the upper and lower drawer doors 2 and 3 have a structure in which a self-closing force is applied as in the prior art, the upper and lower drawer doors 2 and 3 are opened immediately after the upper and lower drawer doors 2 and 3 are opened. Since the doors 2 and 3 are displaced upward by the distance A, a gap 20 between the lower surface of the upper drawer door 2 and the upper surface of the lower drawer door 3 is obtained.
FIG. 14 shows the distance A and the margin B shown in FIG.
Is set to the gap size C shown in FIG. 7, and the members are allowed to shift so as not to interfere with each other.

Here, in the conventional upper and lower drawer doors 2 and 3, since the upper and lower surfaces are horizontal and flat, the gap 20 having the gap size C appears on the outer surface of the refrigerator as it is, so that the appearance of the external appearance is improved. There was a problem of bad.

Incidentally, Japanese Utility Model Laid-Open No. 5-17480 discloses that
It describes that the gap between the opposing surfaces of the left and right doors that open and close in a double-open manner is narrowed in front of the door and widened behind the door, to improve the appearance of the refrigerator, but drawers that use self-closing force In refrigerators having doors, none of the refrigerators has solved the poor appearance of the appearance caused by the gap allowing the drawer door to shift.

In Japanese Unexamined Utility Model Publication No. 5-17480, in order to prevent interference when opening and closing the left and right doors (when rotating around the axis) and to make the gap narrow in front of the doors, the left and right doors have opposite surfaces. Since each of them is inclined, a design change is required for both the left and right doors.

In view of the above, it is an object of the present invention to provide a storage door structure which can easily and inexpensively eliminate poor appearance caused by a gap which allows displacement of a drawer door.

[0010]

According to the present invention, a drawer door for opening and closing an opening of a storage main body is guided while being shifted during opening and closing, and the drawer door is provided between the drawer door and another member of the storage. In the door structure of the storage in which the gap allowing the shift is formed, the surface facing the other member in the shift direction of the drawer door is such that the outer gap dimension of the gap is smaller than the inner gap dimension. And is formed so as not to interfere with the other members. More specifically, the outer end of the surface of the drawer facing the other member in the direction of displacement of the drawer door projects more toward the other member than the inner end.

Here, the surface facing the other member in the direction of displacement of the drawer door is, for example, the upper surface of the drawer door when the drawer door is displaced upward, and the outside of the gap is defined as the outside of the gap. The inside of the gap is closer to the outside than the outside of the storage.

As a specific example, a drawer door for opening and closing the opening of the storage main body is guided so as to be opened while being displaced upward and automatically closed while returning to the original position, and the upper surface of the drawer door and other members of the storage are provided. The height of the outer end of the upper surface of the drawer door is higher than the height of the inner end of the storage door in which a gap allowing the upward movement of the drawer door is formed between It is set. Thus, only by changing the design of the upper surface shape of the drawer door, the gap outside the gap allowing the shift of the drawer door is narrowed, and the appearance of the storage is improved.

[0013] Further, a protruding piece protruding toward the other member is provided at an outer end of a surface of the drawer door facing the other member in the direction of displacement. Thereby, the distance between the outer end of the facing surface of the drawer door and the other member, that is, the gap outside the gap allowing the shift of the drawer door, is reduced, and the appearance of the storage is improved.

Further, another member is provided with a shielding portion for concealing the inside of the gap allowing the displacement of the drawer door.
Thereby, the members inside the storage can not be seen through the gap, and the appearance of the storage can be further improved.

Between the lower opening / closing door 32 and the upper drawer door 33 and between the upper and lower drawer doors 33, 34, shielding members 38, 39 extending in the left-right direction to the front opening of the refrigerator body 30 are provided. Are located.

As shown in FIGS. 1 and 3, the upper and lower drawer doors 33 and 34 are provided with upper and lower caps 41a and 41b and lower caps 42a and 42a, respectively, at the upper and lower ends of the flat decorative plates 40a and 40b. 42b and the decorative board 40
Door sashes 43a and 43b having gasket fitting grooves are respectively incorporated into the side ends of the upper and lower caps 41a and 41b and the lower caps 42a and 42b to form a door housing, and foam insulation is provided in the door housing. Material H is filled, inner plates 44a, 44b are fixed to the door housing so as to face decorative plates 40a, 40b, and gaskets 45a, 45b are fitted into gasket fitting grooves of door sashes 43a, 43b. Have been.

Frame assemblies 50, 51 for guiding the door housing in the front-rear direction of the refrigerator body 30 are attached to the upper and lower drawer doors 33, 34, respectively. As shown in FIGS. 1, 3, and 4, the frame assemblies 50 and 51 include a pair of left and right frames 52 and 53 having front ends bent in an L shape fixed to the inner plates 44a and 44b, respectively. A pair of left and right rails 5 rotatably held at the rear portions of the frames 52 and 53 and arranged on the inner surface of the refrigerator body 30 in the front-rear direction.
Rollers 56 and 57 rollably fitted in the rollers 4 and 55
And connecting rods 58, 59 connecting the rear ends of the frames 52, 53 to each other. Note that each frame 5
Storage cases 60 and 6 for storing refrigerated items
1 is detachably attached.

The lower surfaces of the frames 52, 53 are placed on a pair of left and right rollers 62, 63 attached to the front of the inner surface of the refrigerator body 30, and the frames 52, 53
Are slidable in the front-rear direction of the refrigerator body 30. Further, inclined portions 52a, 53a which are inclined upward and forward are formed at the lower front portions of the frames 52, 53.

Thus, when the upper and lower drawer doors 33, 34 are pulled forward, the frames 52, 53 and the storage cases 60, 61 are integrally moved forward, and the inclined portions 52a,
As the 53a slides on the rollers 62, 63, the upper and lower drawer doors 33, 34 are opened while being shifted upward (diagonally upward) by a distance A shown in FIG. , The frames 52, 53 and the storage cases 60, 61 move integrally backward, and the inclined portions 52 a, 53 a slide on the rollers 62, 63 just before closing, so that the upper and lower drawer doors 33, 34. Automatically returns to its original position (moves diagonally downward) and closes tightly (the self-closing force works). With such a structure, the upper and lower drawer doors 33 and 34 do not close and are slightly opened without being closed tightly, and cool air escapes from the gap between the upper and lower drawer doors 33 and 34 and the refrigerator body 30 to the outside. Is prevented.

In the above structure, the upper and lower drawer doors 33, 34
The upper and lower drawer doors 33 and 34 are shifted upward by a distance A when the door is opened, so that when the upper and lower drawer doors 33 and 34 are closed, the upper surface of the upper drawer door 33 and the lower surface of the lower open / close door 32 are closed. And the gap 65 between the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 need to be set in consideration of deviation.

Here, the gap between the upper surface of the upper drawer door 33 and the lower surface of the lower opening / closing door 32 and the gap 65 between the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 are the same. Therefore, the gap 65 will be described. In the gap 65, when the lower drawer door 34 is pulled out toward the user and the inclined portion 53a reaches the roller 63, the lower drawer door 3
4 begins to shift upward, so that the inclined portion 53a
Even if the gap size is reduced before reaching the upper side, the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 do not interfere with each other, and after the inclined portion 53a reaches the roller 63, The gap size needs to be widened so that the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 do not interfere with each other.

For this reason, if the inside of the gap 65 is widened, the opening and closing of the lower drawer door 34 will not be affected even if the outside of the gap 65 is narrowed. Therefore, the inside of the gap 65 is the gap dimension C shown in FIG. 1 in which the distance A and the margin dimension B shown in FIG. 5 are combined, and the outside of the gap 65 is the same as the margin dimension B narrower than the inside. As described above, the height position of the surface facing the other member (the lower surface of the upper drawer door 33) in the direction of displacement of the lower drawer door 34, that is, the outer end (front end) of the upper surface of the lower drawer door 34 is the inner end. It is set higher than the height position of the part (rear end). Specifically, the upper cap 41b corresponding to the upper surface of the lower drawer door 34 has a shape inclined downward from the front end to the rear end. The lower cap 42 corresponding to the lower surface of the upper drawer door 33
a is flat and horizontal as in the conventional case. Thereby, the outer dimension of the gap 65 becomes narrower than before, so that the appearance of the refrigerator can be improved and a sense of quality can be provided.

If the upper surface of the upper drawer door 33 has the same shape as the upper surface of the lower drawer door 34, the outside of the gap between the upper surface of the upper drawer door 33 and the lower surface of the lower open / close door 32 can be made smaller than before. The refrigerator can also be made narrower to further improve the appearance of the refrigerator.

As shown in FIGS. 6 and 7, the lower cap 42a corresponding to the lower surface of the upper drawer door 33 is formed to be inclined upward from the front to the rear.
By forming the upper cap 41b corresponding to the upper surface of the upper part 4 into a shape inclined downward from the front end part to the rear end part, if the above-mentioned clearance dimension is provided, a high-grade feeling can be provided similarly to the above. Can be. However, in this case, the design of the lower cap 42a on the lower surface of the upper drawer door 33 is changed, which is not desirable in terms of cost.

Further, as shown in FIG. 8, in the upper cap 41 b corresponding to the upper surface of the lower drawer door 34, the lower drawer door 34 is pulled out to the front and the upper part when the inclined portion 53 a reaches the roller 63. If the step portion 70 is provided on the front side of a position just below the front end of the lower cap 42a of the drawer door 33 so as to have the above-described gap size, it is possible to give a sense of quality as described above.

Next, the operation for opening and closing the lower drawer door 34 will be described. First, when opening the lower drawer door 34, the lower drawer door 34 is pulled out to the near side. Then, the lower surface of the frame 53 slides on the rollers 63, and the frame 53 and the storage case 61 move integrally forward. When the inclined portion 53a of the frame 53 reaches the roller 63, the lower drawer door 34 is lifted upward. At this time, since the upper cap 41b corresponding to the upper surface of the lower drawer door 34 has a shape inclined downward from the front end to the rear end, the front end of the lower cap 42a of the upper drawer door 33 and the lower end are lower. Upper cap 4 of side drawer door 34
1b is maintained at a substantially constant distance, and the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 do not interfere with each other.
Then, the lower surface of the frame 53 continues to slide on the rollers 63, and the lower drawer door 34 is opened.

When the lower drawer door 34 is pushed in from the open state, the frame 53 and the storage case 61 are integrally moved rearward. The inclined portion 53a of the frame 53 is
, The lower drawer door 34 closes while moving diagonally downward. At this time, even if the push-in is insufficient and the lower drawer door 34 is slightly closed without being closed tightly, the inclined portion 53a slides on the roller 63 due to the weight of the lower drawer door 34 and automatically. Will be closed. The upper drawer door 33 also has a lower drawer door 3.
The same opening / closing operation as in FIG. 4 is performed.

As described above, even if the outside of the gap 65 is narrowed, the lower drawer door 34 is opened when the lower drawer door 34 is opened.
Of the upper drawer door 33 and the upper surface of the lower drawer door 34 do not interfere with each other.

(Second Embodiment) In a second embodiment, as shown in FIGS. 9 and 10, an upper drawer door 33 is provided at the front end of a horizontal upper cap 41b corresponding to the upper surface of a lower drawer door. A projecting piece 80 projecting to the side, that is, upward, is integrally formed. Accordingly, the gap 65 is formed by the protruding piece 80 while the inside of the gap 65 remains the same as the gap dimension C as in the related art.
Of the refrigerator becomes narrower and the gap size becomes B, and the appearance of the refrigerator can be improved.

When the upper surface of the upper drawer door 33 is made to have the same shape as the upper surface of the lower drawer door 34, the outer side of the gap between the upper surface of the upper drawer door 33 and the lower surface of the lower open / close door 32 becomes larger than before. The refrigerator can also be made narrower to further improve the appearance of the refrigerator. Other configurations and operations are the same as those of the first embodiment, and members having the same functions as those of the first embodiment are denoted by the same reference numerals.

As described above, in the conventional structure, just by forming the projecting piece 80 at the front end of the upper cap 41b of the lower drawer door 34, the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 interfere. And the outside of the gap 65 can be narrowed, so that the lower drawer door 34 does not interfere with the lower surface of the upper drawer door 33 and the upper surface of the lower drawer door 34 as in the first embodiment. Compared with the case where the upper cap 41b is inclined or provided with a step, the design can be easily changed, the appearance of the refrigerator can be improved at a low cost, and the refrigerator can have a luxurious feeling.

(Third Embodiment) In the first and second embodiments, the outside of the gap 65 is narrowed. However, since the outside and the inside of the gap 65 are at the same height position, the gap 65 Through this, the shielding member 39 inside the refrigerator main body 30 can be seen, and the external appearance of the refrigerator may be deteriorated.

Therefore, in the third embodiment, FIG.
As shown in FIGS. 1 and 12, the lower cap 42a corresponding to the lower surface of the upper drawer door 33 is provided with a shielding portion 90 for concealing the inside of the gap 65. The shielding portion 90 is configured to protrude downward from the front end of the lower cap 42a slightly backward to the rear end. The gap 6
The inside of 5 has a gap D that is smaller than the gap C by the amount of the protrusion of the lower cap 42a, but is in a range in which the displacement of the lower drawer door 34 can be tolerated.

As a result, the outer height position of the gap 65 is higher than the inner height position, so that the shielding member 39 inside the refrigerator body 30 cannot be seen through the gap 65, and the appearance of the refrigerator is reduced. The appearance can be further improved, and the sense of quality can be further increased.

If a shielding portion is provided on the lower surface of the opening / closing door 32 even in the gap between the upper surface of the upper drawer door 33 and the lower surface of the lower opening / closing door 32, the shielding member 38 inside the refrigerator main body 30 passes through the gap. Can no longer be seen, and the appearance of the refrigerator can be further improved. Other configurations and operations are the same as those of the second embodiment, and members having the same functions as those of the second embodiment are denoted by the same reference numerals.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention. For example, the present invention may be applied not only to a refrigerator but also to a storage simply storing foods and the like. Although the drawer doors are arranged in two stages in the upper and lower stages, one, three or more stages in the upper and lower stages, or a plurality of stages may be horizontally arranged. Further, the drawer door may be shifted in the left-right direction during opening and closing. In this case, the gap allowing the shift is located on the side of the drawer door,
What is necessary is just to comprise the side surface shape of a drawer door similarly to the upper surface shape of the drawer door in the said embodiment. In the second embodiment, the projecting piece is provided integrally with the front end of the upper cap of the lower drawer door, but may be a separate member. In the third embodiment, the shielding portion is provided integrally with the lower cap of the upper drawer door, but may be a separate member. The shielding portion in the third embodiment may be provided on the lower surface of the upper drawer door or the lower surface of the lower opening / closing door in the first embodiment.

[0038]

As is apparent from the above description, according to the present invention, the surface facing the other member in the direction of displacement of the drawer door is such that the gap outside the gap allowing the displacement of the drawer door is the inner gap. Since it is formed so as to be narrower than the dimensions and so as not to interfere with other members, it is possible to make the gap dimension outside the gap narrower than before, improve the appearance of the storage, and have a sense of luxury Can be made.

Further, the outer end of the surface facing the other member in the direction of displacement of the drawer door is made to protrude toward the other member from the inner end to reduce the size of the gap outside the gap, and the drawer door moves upward. In the case of displacement, the height position of the outer end of the upper surface of the drawer door is set higher than the height position of the inner end portion to reduce the gap size outside the gap, so that one side of the drawer door It is possible to give a sense of quality with only a slight design change.

Further, by providing a protruding piece protruding toward the other member at the outer end of the surface facing the other member in the direction of displacement of the drawer door, the gap outside the gap allowing the displacement of the drawer door can be reduced. It is narrower than the inner clearance dimension and can be made to not interfere with other members, making it easier to change the design compared to changing the shape of the facing surface, improving the appearance of the refrigerator at low cost, and feeling luxurious Can be provided.

Further, by providing a shielding portion for concealing the inside of the gap that allows the drawer door to shift in the other member, the member inside the storage can not be seen through the gap,
The appearance of the storage can be further improved, and the luxury can be further enhanced.
