Description

  The present invention relates to a refrigerator in which a storage container is taken in and out by a drawer door, and more particularly to an apparatus in which the amount of drawer of the container is increased.

  In recent years, refrigerators have a tendency to increase in storage capacity with diversification of life. As a form, a refrigerator compartment with the largest storage capacity is installed in the upper part, and an ice making room with a relatively small storage capacity in the lower part. There are many types in which a temperature switching chamber is divided into left and right in the width direction, a vegetable room is provided at the lower part, and a freezing room is provided at the lowermost part.

  The refrigerating room is closed in a rotating manner by a door pivoted on one side in the vicinity of the front opening or by a double door, and the vegetable room, the freezer room, the ice making room, and temperature switching Most of the chambers have a container attached to the storage chamber side of the door and a drawer type in the front and rear for the convenience of taking in and out the stored items.

  Conventionally, in a drawer-type door container structure in a refrigerator, as shown in FIG. 8 which is a longitudinal sectional view of the drawer door, a drawer door (with a gap provided between the receiving surface on the storage chamber body side sealed by a gasket provided on the periphery) A pair of left and right support frames (51) for holding the container (52) are fixed to the inner surface side of the storage chamber 50), and the support frame (51) is connected to the storage chamber via pulleys (55) (56). By being slidably arranged along rails (53) provided on both sides, the door (50) can be pulled out in conjunction with opening and closing.

  The support frame (51) pulled out when the door is opened receives a lower surface of the support frame (51) by a pulley (56) provided in the vicinity of the opening of the storage chamber, and is attached to the rear end of the support frame ( 55) is supported by two rails (front and rear) supporting the rail (53), and the pulled-out state is maintained.

On the other hand, in the above configuration, the drawn out door (50) and the container (52) have a considerable weight depending on the amount of storage, but in order to support this, the distance between the two front and rear points is As shown in FIG. 9, the slide rail is fixed to the fixed rail (31a) and the movable rail because the length of the container (52) is shortened and the depth dimension of the container (52) is shortened. (31b) Further, by adopting a composite system having an intermediate traveling rail (31c) and fixing the moving rail (31b) to the door support member and engaging the container (32), the pulling amount is increased and the backlash is small. A refrigerator having a high-quality drawer door has been proposed (see, for example, Patent Document 1).
JP 2006-177653 A (paragraphs [0051] [0061])

  However, in the drawer rail configuration described in Patent Document 1, the fixed rail (31a) is fixed to the side surface of the inner box (20), and the movable rail (31b) is directly connected and supported to the drawer door such as the vegetable compartment or the freezer compartment. Therefore, when actually assembling the drawer door, the door must be attached to the moving rail (31b) of the rail member (31) fixed to the side of the inner box (20) in advance, and the rail is pulled out. It is extremely unstable that it is attached to the door in the wet state, and the installation work in the vegetable room or freezer compartment, which is a small space in terms of the work environment, including installation accuracy and subsequent adjustment, is extremely complicated and difficult. Is.

  On the other hand, a configuration is also described in which a door support member fixed to the door is disposed and fixed to the moving rail after the rail member is mounted in the cabinet. In this case, the door support member corresponds to the amount of the container to be pulled out. Due to the depth length, the work of fixing this to the moving rail pulled out over the entire depth dimension is unstable and complicated as described above. At the same time, since the door support member with a long depth is fixed to the door in advance, the assembly error and the variation in the mounting level become large, and the difference in parallelism with the rail member side, for example, the door support member to the door If the mounting angle does not match the rail member fixed to the inner box, it will be attached forcibly, and the stress of the rail member due to the door pulling action will increase, making the sliding operation difficult or deformed. Adverse effects will occur. In order to prevent this, since a high degree of mounting work accuracy such as parallelism between the two is required, it becomes a very complicated work form, leading to a reduction in work efficiency.

  The present invention has been made paying attention to the above points, and when adopting a so-called double rail type slide rail that increases the amount of the container pulled out by the drawer door, it is easy to attach the door to the slide rail. An object of the present invention is to provide a refrigerator capable of reducing man-hours and eliminating a mounting variation between a drawer rail and a door support portion with a simple configuration and smoothly performing a sliding action without stress.

Refrigerator of the present invention includes a pull-out door for closing the front opening of the storage chamber openably, a pair of right and left support frames drawn with the door opening is fixed to the inner side of the door, provided on a side edge a container to be held by placing the flange portion to the support frame, and reinforcing ribs formed at predetermined intervals over the depth direction of the container the flange of the container, Wataru in the longitudinal direction on both sides of the storage compartment A slide rail formed by a fixed rail fixed to the inner box side, an intermediate rail that engages and slides with the fixed rail, and a movable rail that engages and slides with the intermediate rail , A rail reinforcing plate fixed to the heat insulating material side of the inner box forming the storage chamber so as to support the slide rail, and the container formed substantially integrally with the movable rail and fixed so as to overlap the support frame. and a supporting member for holding the The length of the lifting frame and the depth length less than half the length of the container, characterized in that to prevent the floating of the support frame to the lower surface of the reinforcing ribs in close proximity or contact on the support frame Is.

  According to the present invention, not only the stored food can be stored and taken out easily by increasing the pull-out amount of the storage container held on the door, but also the slide rail can be easily attached to the main body and at the time of sliding. It is possible to reduce the stress of the rail member and perform a smooth pulling operation.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a refrigerator (1) in which the open state of each door is indicated by a two-dot chain line. The inner box (4) provided inside the outer box (2) via a heat insulating material (3). A storage space is formed and divided into a plurality of storage chambers by a heat insulating partition wall (5). (6) is a refrigerating room disposed at the upper part of the main body, and pivotally supports a folding door type refrigerating room door (7) by hinges provided on both sides of the front opening to close the opening. .

  In the lower part of the refrigerator compartment (6), a relatively small volume temperature switching chamber (7) and an ice making chamber (not shown) are arranged side by side through a heat insulating partition wall (5). A vegetable room (8) for storing vegetables and the like is disposed, and a freezer room (9) for storing frozen food is disposed at the bottom.

  These storage rooms other than the refrigerating room (6) have a smaller storage capacity than the refrigerating room and are easy to use due to the installation height position of the storage room, as shown by a two-dot chain line in FIG. It is a method.

  Hereinafter, the configuration will be described by taking the vegetable room (8) as an example. As shown in FIG. 2, which is a schematic side view showing the drawer state of the container with a dotted line, an inside fixing portion is provided on the inner side of the door (10) for closing the front opening of the vegetable compartment (8) so as to be freely opened and closed. A pair of left and right support frames (11) that form a support portion (11b) having a length of about several tens of centimeters that extends in the interior depth direction and bends substantially in an L shape together with (11a) are fixed. The container (12) is held by slide rails (13) arranged in the front-rear direction on both side walls of the vegetable compartment (8) together with the frame (11), and the drawer system is slidable back and forth.

  At the rear of the container (12), coolers (14) (14 ') and fans (15) (15') that generate cold air and supply it to the storage rooms of the refrigeration space and the freezing space are arranged. A gasket made of soft synthetic resin is inserted into the inner peripheral edge of the vegetable compartment door (10) placed at the front opening of the vegetable compartment (8), and inside the vegetable compartment (8) when the door is closed Is configured to be sealed.

  FIG. 3 is an exploded perspective view of the slide rail (13) related parts, and FIG. 4 is a cross-sectional view from the front of the slide rail (13) portion of FIG. 3 in the left support portion of the container (12). In addition, the slide rail (13) is provided on the upper and lower sides of a plate-like body made of a steel plate fixed to both inner surfaces of the inner box (4) forming the vegetable compartment (8) so as to extend in the depth direction of the vegetable compartment (8). A fixed rail (16) provided with a flange portion (16a) extending inward on the side, and a support portion (11b) on the indoor depth side of the support frame (11) supporting a part of the container (12) A flange member (11c) formed on the upper surface engages with the upper surface of the support member (19), and the support member (19) is fixed integrally and positioned between the flange portion (16a) of the fixed rail (16). The movable rail (17) with the flange (17a) extending outward from its upper and lower sides, and the inner and outer rails 16) A hook part (18a) provided between the hook part (16a) of the fixed rail (16) and the hook part (17a) of the movable rail (17) is provided in the inward direction. It is comprised from the provided intermediate rail (18).

  The intermediate rail (18) has a flange (18a) and a ball bearing (20) fitted between the fixed rail (16) and the flanges (16a) (17a) of the movable rail (17). The intermediate rail that engages with each other and is substantially integrated as a slide rail (13) and slidably held back and forth to form a double rail, and slides in the fixed rail (16) By sliding in (18) and the intermediate rail (18), the movable rail (17) is pulled out in two stages.

  The support member (19) is previously fitted along the indoor side of the movable rail (17) and is integrally fitted and fixed with a rivet or the like. The cross-section is substantially L-shaped, and the support frame is formed on the upper side thereof. (11) A flange portion (19a) that engages with the upper edge flange portion is formed. Further, the support member (19) and the movable rail (17) may be integrally formed.

  Therefore, in the state where the slide rail (13) is pulled out from the vegetable compartment (8), the container (12) held on the flange (19a) of the support member (19) fixed to the movable rail (17) is Compared to the conventional single rail system, the rear end of the rear end of the vegetable compartment (8) is largely pulled out in a fully open state by the holding mechanism between the rails (16), (18), and (17).

  The slide rail (13) is attached to the refrigerator body (1) in the following manner. First, a steel sheet rail reinforcement plate (21) extending in the front-rear direction of the vegetable compartment (8) so as to hold the slide rail (13) is positioned and temporarily fixed to the back surface of the side surface of the inner box (4). The rail reinforcing plate (21) is urethane that protrudes outward by filling the gap between the inner box (4) and the outer box (2) with foaming insulation material (3) such as urethane foam by an in-situ foaming method. It is embedded in the foam heat insulating material (3) in a state of being fixed to the back surface of the inner box (4) by an anchor, and is more firmly fixed by solidifying the heat insulating material (3).

  Then, the fixed rail (16) is fixed to the rail reinforcing plate (21) at two locations on the front and rear sides of the fixed rail (16) with screws (22), so that the fixed rail (16), the intermediate rail (18) and the movable rail (17) are fixed. ) Can be fixed to the main body (4) side as a slide rail (13) integrated in an overlapped state.

  Next, as shown in FIG. 2 and FIG. 5 which is a perspective view of the main part, the support part (11) extending into the vegetable compartment (8) of the support frame (11) fixed to the inner left and right sides of the door (10) ( 11b) is engaged with the front end portion of the support member (19), which is the door side of the slide rail (13), and is drilled in the rear end portion of the upper edge flange portion (11c) of the support portion (11b). The holes (11d) are engaged with the engaging claws (19b) cut and raised upward from the upper side flanges (19a) of the corresponding supporting members (19) so as to overlap each other, and the support portions (11b) are moved forward. By engaging the engagement claw (19b) with the engagement hole (11d) in the pulled state, the front portion on the door (10) side of the upper side flange (11c) of the support portion (11b) Are fixed with screws (23) from above to the overlapping support member (19).

  Even if it is a work in a narrow space near the opening of the vegetable compartment (8), and the work environment is complicated because the slide rail (13) always slides back and forth, the door (10 ) Is the engaging claw (19b) at the front end of the slide rail (13) located near the front opening of the vegetable compartment (8) and the engaging hole (11d) of the support frame (11) fixed to the door (10). )), And the door (10) can be pulled out slightly from the opening to the front without pulling the slide rail (13) to the fully open position as before. The attachment work to the main body can be performed very easily, and the workability in the manufacturing process can be greatly improved.

  Needless to say, the relationship between the engagement holes (11d) and the engagement claws (19b) in the support frame (11) and the support member (19) may be reversed. The relationship between the engagement hole (11d) of the support portion (11b) and the engagement claw (19b) of the support member (19) corresponds to the load when pulled forward, and the door ( As an example of pulling out 10), conversely, as a configuration that functions effectively when pushing the door (10) when the door is closed, as shown in FIG. The direction of the engaging claw (19b ') cut and raised from (19a') is formed so that the opening is directed to the door side, contrary to the above embodiment, and the support portion (11b) to the engaging claw (19b ') is formed. ′) With the engaging hole (11d ′) of the upper surface flange part (11c ′) pushed into the indoor side, the supporting part (11b ′) and the supporting member (19 ′) overlapping with each other are screwed in the same manner as described above. You just have to do it.

  Further, the support frame (11) fixed to the vegetable compartment door (10) can be held back and forth by the slide rail (13) via the support member (19), and is L-shaped. Since the support part (11b) to the indoor side of the support frame (11) that extends is extended with a short depth length, the engagement distance with the support member (19) is short, and the slide frame (13) Since the door (10) can move in the width direction to a certain degree of freedom, it must slide back and forth while maintaining the parallelism of the slide rails (13) attached to both side walls of the inner box (4). And an effective drawer container mechanism can be formed.

  Therefore, unlike the conventional case, the door support member fixed to the door and the main body side at a long distance comparable to the depth length of the container (12) and the moving rail do not overlap with each other. Slide operation is difficult because it is not forcibly assembled due to the difference in size or parallelism of both, and it can absorb the stress on the slide rail (13) and door (10) side by assembly. It is possible to prevent the adverse effects of becoming and deforming, and this can be achieved with a simple configuration without requiring effective materials and high work accuracy.

  Further, the support frame (11) can be reduced in size by the above, and the cost can be reduced, and the strength of the drawer door (10) can be reduced by the engagement claw (19b) portion of the support frame (11) and the support member (19). The distance from the screw fixing part may be a predetermined distance or more. For example, even if the distance is not more than half of the depth length of the container (12), it has sufficient support strength due to overlapping.

  And the container between the holding frame formed by the upper hook part (11c) of the left and right support frames (11) in the state pulled out together with the vegetable compartment door (10) and the upper hook part (19a) of the support member (19) By placing the peripheral flange portion (12a) of (12), the container (12) is held so as to be able to be drawn back and forth with respect to the main body. As shown in FIG. 2, the container (12) can be pulled out of the main body to the rear end portion by the slide rail (13) of the type, so that the stored food can be easily stored and taken out.

  At this time, since the intermediate rail (18) and the movable rail (17) have a predetermined length of overlap with respect to the fixed rail (16), the swing in the width direction is restricted and the door portion swings greatly. This can be prevented, and the door closing operation of pushing the container (12) into the cabinet with the door (10) can be performed smoothly.

  Further, the outer side formed on the peripheral edge of the upper opening of the container (12) held between the flanges (11c) (19a) of the support frame (11) of the door and the support member (19) of the slide rail (13) As shown in FIG. 7, the inverted U-shaped flange (12a) that extends horizontally to the outside and hangs downward from the outer end is an upper surface flange of the support member (19) that forms the slide rail (13). It is formed so as to hang down sufficiently so as to cover (19a).

  By configuring in this way, a large amount of food is stored in the container (12), and the upper part of the left and right wall surfaces of the container (12) is deformed and moved so as to fall inward due to its weight. In addition, the strength of the container (12) itself is improved by the flange (12a), and the hanging portion of the flange (12a) is supported by the support frame (11) and the support member (19) even if deformed inward. Since it abuts against the flanges (11c) and (19a), it is possible to prevent further deformation and to prevent the dropout from the holding frame part, thereby maintaining a predetermined container shape.

  When the container (12) is deformed, the support frame (11) or the upper surface flange (11c) (19a) of the support member (19) that is normally hidden by the flange (12a) of the container The exposed screws (23) and engaging claws (19b) fixing the support frame (11) are visible and the appearance is impaired. (11c) (19a) can be prevented from being exposed. Furthermore, if the edges of the support frame (11) and the support member (19) are exposed, this part may be a metal plate, which may cause injuries to fingers, etc. Will always be covered with the buttocks (12a) and can prevent injury.

  Similarly, in the space formed by the horizontal portion and the hanging portion of the flange portion (12a) provided on the side edge of the container (12), a reinforcing rib (12b) for connecting the upper portion and the hanging portion of the container body. Are formed at predetermined intervals along the depth direction of the container (12). The reinforcing rib (12b) has a lower surface in proximity to or in contact with the flanges (11c) and (19a) on the support frame (11) and the support member (19) of the slide rail (13).

  As described above, in the configuration in which the support frame (11) of the door (10) is reduced in size and engaged with the support member (19) of the slide rail (13) and connected, the door may vary due to variations during installation. When the (10) and the container (12) are pulled out, the support frame (11) and the support member (19) are slightly displaced, and one of them floats, and there is a concern that the container (12) is deformed by the stress. However, the overall strength of the container (12) is further improved by the reinforcing rib (12b), and food or the like is normally stored in the container (12). ) Presses the support frame (11) and the support member (19) from the upper part, and prevents the container (12) from being deformed by preventing lifting.

  In addition, although each said Example demonstrated by the example of the drawer-type door (10) in the vegetable compartment (8) of a refrigerator, it is not restricted to this, The ice storage box in a freezer compartment (9) or an ice making room, a temperature switching room, etc. Needless to say, it can also be adopted as a structure of a drawer-type door container of another storage room.
