Description

  The present invention relates to a refrigerator in which a storage container disposed in a storage room is put in and out by a drawer-type door, and more particularly, to a refrigerator that achieves stable drawer operation and improvement in manufacturing quality.

  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 In many chambers, a container is attached to the storage chamber side of the door and a drawer type is provided in the front and rear direction for the convenience of taking in and out the stored items.

And as a drawer structure in the door of the refrigerator, as shown in FIG. 10 which is a longitudinal sectional view of the drawer door, the drawer type in which the gap with the receiving surface on the storage chamber (51) side is sealed by a gasket provided at the periphery A pair of left and right support frames (55) for holding the container (57) are fixed to the inner surface side of the door (54) of the door, and the support frame (55) is fixed through the support member (59). A compound-type slide rail (56) which has a fixed rail (58) fixed to the box side, an intermediate rail (61), and a movable rail (60), and is connected by a ball bearing inserted between the flanges. The amount of drawer is fixed by being slidable along the slide rail (56) located on both sides of the storage chamber (51) so that it can be pulled out in conjunction with opening and closing of the door (54). In the pulled out state There has been proposed a refrigerator that reliably supports the door (54) and the container (57), and has a high-quality drawer-type door with little backlash (see, for example, Patent Document 1).
JP 2007-064580 A

  However, the slide rail (56) fixed to the side surface of the inner box (53) forming the storage chamber (51) in the configuration of Patent Document 1 is a rail reinforcement attached to the heat insulating material side on the back surface of the inner box (53). As is understood from FIG. 11 which is an exploded view of the plate (67), the slide rail (56) provided in one storage chamber and the rail reinforcing plate (67) holding the slide rail (67) are fixed. ) Is a set, and a configuration in which a plurality of slide rails (56) are arranged in the storage chamber is not considered.

  That is, the slide rail (56) so far is provided for storage rooms such as freezer rooms and vegetable rooms other than the refrigerator compartment provided at the top of the vertical refrigerator as described above. The heights of the target storage rooms are relatively low, and inevitably have only enough space to provide one slide rail (56). When installing the refrigerator in the kitchen, it will be applied to a so-called horizontal refrigerator that has a horizontally wide outer shape with a width dimension larger than the height dimension set to the user's waist position. Since the height dimension is about 800 mm and the doors are all drawer-type, considering the ease of use, a plurality of slide rails are arranged on the side wall of one storage chamber. .

  Therefore, in this case, it is necessary to increase the reinforcement strength because the load on the slide rail and the load increase. However, if the rail reinforcement plate is increased for each slide rail, the weight of the entire rail device increases. In the case of an overload, not only the so-called inward collapse occurs in which the reinforcing plate falls to the inside of the storage chamber, but also causes a problem that the number of parts increases and the assembly work becomes complicated.

  The present invention has been made paying attention to the above points, and not only ensures a stable pulling-out operation of the pull-out container, but also improves the manufacturing quality such as the positioning of the slide rail with respect to the main body position, thereby improving the quality as a pull-out container. It aims at providing the refrigerator which can aim at improvement of.

  The refrigerator according to claim 1 of the present invention includes a container provided in a storage chamber whose front opening is closed openably and closably by a drawer-type door, and side walls on both sides of the storage chamber so as to hold the container removably. A single rail reinforcing plate fixed to the heat insulating material side of the inner box that forms the storage chamber so as to support the plurality of slide rails, and a plurality of slide rails that are installed in the front-rear direction and attached in the vertical direction. The slide rail located at the lowermost position among the plurality of slide rails is fixed to a pair of left and right support members that are fixed to the inner surface side of the drawer-type door and pulled out together with the opening door. The refrigerator according to claim 6 divides the inside of the heat-insulating box body having a horizontally long outer shape by making the width dimension larger than the height dimension, and the lower section is set to the left and right. A plurality of storage chambers are formed by dividing into heat, a container is provided in the storage chamber whose front opening is closed by a pull-out door, and slide rails that can be pulled out freely are provided on side walls on both sides of the storage chamber. A plurality of slides are attached to the heat insulating material side of the inner box forming the storage chamber so as to support the plurality of slide rails, and attached to the heat insulating material side of the inner box so as to support the plurality of slide rails. The slide rail located at the lowermost of the rails is fixed to a pair of left and right support members that are fixed to the inner surface side of the pull-out door and pulled out together with the opening door.

  According to the present invention, it is possible to stabilize the pulling-out operation of the container held on the pull-out door by increasing the mounting strength of the slide rail, improve the manufacturing quality such as positioning the slide rail with respect to the body position, and simplify the work process. It is possible to improve the quality as a pull-out container.

  Hereinafter, the configuration will be described by taking the refrigerator compartment (11) as an example. As shown in FIG. 3 which is a side view of the inside of the refrigerating chamber and FIG. 4 which is a perspective view below the refrigerating chamber, the inside of the refrigerating chamber door (14) which closes the front opening of the refrigerating chamber (11) so as to be openable and closable. A pair of left and right support frames (15b) formed with a fixing portion (15a) to the door body and a supporting portion (15b) that is bent from the fixing portion (15a) into an approximately L shape and extends in the interior depth direction. ), And a container (17) for storing stored foods, etc., is held by slide rails (16) placed in the front-rear direction on both side walls of the refrigerator compartment (11) together with the support frame (15). The drawer system is slidable back and forth.

  Although not particularly shown, a cooler and a fan that generate cold air and supply it to each storage room in the refrigeration space and the freezing space are arranged at the rear of the container (17), and the inner side of the refrigeration room door (14) A gasket made of a soft synthetic resin is inserted into the peripheral portion, and the inside of the refrigerator compartment (11) is sealed when the door is closed.

  As shown in FIG. 5 which is an exploded perspective view of the slide rail (16) related parts, and FIG. 6 which is a cross-sectional view from the front of the slide rail (16) portion in the left support portion of the container (17), The slide rails (16) are provided on the upper and lower sides of a plate-like body made of steel plates fixed to the inner surfaces of both sides of the inner box (3) forming the refrigerator compartment (11) so as to extend in the depth direction of the refrigerator compartment (11). A fixed rail (18) provided with a flange portion (18a) extending in the direction, and a flange portion (15c) formed on the upper surface of the support portion (15b) of the support frame that supports both side edges of the container (17) A support rail (19) that supports the arm is integrally fixed, and the flange (20a) extends outward from the upper and lower sides so as to be positioned between the flanges (18a) of the fixed rail (18). (20) and the flange (18a) of the fixed rail (18) provided between the inner and outer rails (18) and (20). ) And a flange (20a) of the movable rail (20), and an intermediate rail (21) provided with a flange (21a) positioned inward.

  The intermediate rail (21) has a flange (21a) and a ball bearing (22) fitted between the fixed rail (18) and the flanges (18a) (20a) of the movable rail (20). The intermediate rail that engages with each other and is substantially integrated as a slide rail (16) and slidably held back and forth to form a double rail, and slides in the fixed rail (18) The movable rail (20) is pulled out in two stages by sliding in (21) and the intermediate rail (21).

  The support member (19) is placed along the indoor side of the movable rail (20) and is integrally fitted and fixed with a rivet or the like. The cross section is substantially L-shaped, and the container (17 ) (19a) for holding the support frame (15) on which is mounted. The support member (19) may be formed integrally with the movable rail (20).

  When the slide rail (16) is pulled out from the refrigerator compartment (11) together with the refrigerator door (14) by the opening operation, the flange (15c) of the support frame (15) fixed to the support member (19) is provided. ) The container (17) held by placing the peripheral flange (17a) on it is held in a two-stage manner between the rails (18), (20) and (21) as compared to the conventional single rail system. The rear end of the refrigerator (11) is largely pulled out from the front opening of the refrigerator compartment (11) by the mechanism, and the container (17) can easily take out and store the food from the upper opening in the fully open state.

  At this time, the intermediate rail (21) and the movable rail (20) have a predetermined length of overlap with respect to the fixed rail (18), so that the swing in the width direction is restricted and the door portion swings greatly. This can be prevented, and the door closing operation in which the container (17) is pushed into the cabinet with the refrigerator door (14) can be smoothly performed.

  Above the container (17) held by the slide rail (16), a slide rail upper (23) and a slide rail (24) having the same configuration are provided. Unlike the slide rail (16), the slide rail upper (23) and the middle (24) are not connected to the refrigerator compartment door (14) and are fixed to the support member (19). The support frame (15) has a configuration in which both side edges of the container (17) are held by the flanges (15c) extending forward and backward of the upper edge of the support frame (15), and the container (17) is placed and pulled out. ), The storage drawer operation on the container (25) placed in the same (24), the inside of the container (26) into the refrigerator compartment (11) is performed by the operation of the user's fingers, Like the container (17) by the slide rail (16), it can be pulled out to the outside with full open.

  Thus, the inner box (3) corresponding to the three slide rails (23), (24), and (16) extending up and down the side wall of the refrigerator compartment (11), on the heat insulating material (4) side on the back surface, A rail reinforcing plate (27) made of a steel plate having a height dimension and a depth dimension so as to substantially cover the three slide rails (23) (24) (16) is attached.

  When mounting the rail reinforcing plate (27), the protruding piece (27a) provided on the plate surface is positioned and temporarily fixed by engaging the engaging hole (3a) formed on the side surface of the inner box (3). The front and rear parts are fixed with screws (28) along the rails from the storage room side, and then urethane foam is formed in the gap between the inner box (3) and the outer box (2) by an in-situ foaming method. The rail reinforcement plate (27) is embedded in the foam insulation (4) by foaming and filling the insulation (4), etc., and is firmly fixed to the inner box (3) by solidifying the insulation (4) Is done.

  The fixed rail (18), the intermediate rail (21), and the movable rail (27) are fixed to the rail reinforcing plate (27) by fixing two positions in the depth direction of the fixed rail (18) with screws (29). 20) can be fixed to the inner surface side of the inner box (3) as a slide rail (16) integrated in an overlapped state.

  The above slide rail (23) and the same (24) are located above the container (17) pulled out together with the slide rail (16) of the pull-out door (14), and the container (25 ) (26) is pulled out by the user's hand, and although not particularly shown, the single rail of the fixed rail (18 ') and the movable rail (20') from which the intermediate rail (21) has been removed is not shown. In this case, the amount of drawer of the containers (25) and (26) is the same as in the case of the single rail system.

  With the above configuration, even when a plurality of slide rails (23), (24), and (16) are arranged on the side wall in the refrigerator compartment (11), it is only necessary to attach a single rail reinforcing plate (27). The mounting position between the slide rails (23), (24), and (16) is regulated, and variations can be suppressed even during the pull-out operation, so that the quality of the product can be improved. Compared to a configuration in which rail reinforcement plates are attached and a connecting member is required for positioning each rail reinforcement plate, the attachment work can be simplified and the number of work steps can be reduced.

  Moreover, since the rail reinforcing plate (27) is a single reinforcing plate extending over the slide rails (23), (24), and (16), the side surface of the inner box (3) to which the plurality of slide rails are attached is Because it is reinforced in a large range, its strength is increased, and a large amount of food is stored in the containers (25), (26), and (17), and the upper part of the left and right wall surfaces of the inner box (3) falls inward due to its weight It is possible to prevent the occurrence of so-called inward collapse that is deformed as described above, and it is possible to reduce the cost. In addition, if a through-hole (30) is appropriately drilled in an appropriate part of the rail reinforcing plate surface so as to be engaged with the inner box (3), positioning becomes more reliable and the strength of the reinforcing plate is maintained while maintaining strength. Weight can be reduced.

  Next, another embodiment of the present invention will be described. As shown in FIG. 7 which is a side view of the inside of the refrigeration chamber, in which the same parts as those in FIG. 3 are denoted by the same reference numerals, FIG. 8 which is a sectional view from the front, and FIG. 9 which is an exploded perspective view of related parts. On both side wall surfaces of the chamber (11), slide rails (16 ') similar to those of the above-described embodiment that slide forward and backward while holding the container and the support frame are arranged in the front-rear direction. And in the said vertical partition wall (6 ') which forms one side wall of a refrigerator compartment (11), the said ice-making room (8 adjacent to the said slide rail (16') and vertical partition wall (6 ')) (8) ) A rail reinforcing plate (32) for attaching the slide rail R (31) holding the container in the upper refrigerated space (10) is provided.

  The rail reinforcing plate (32) has a substantially S-shaped cross section so as to extend over the left and right inner boxes (3) and (3 '), and a horizontal portion corresponding to the thickness of the vertical partition wall (6') ( 32d) and reinforcing attachment portions (32b) and (32c) extending vertically from both ends thereof.

  And each reinforcement attaching part (32b) (32c) is temporarily fixed by the protrusion (32a) and the engagement hole (3a) of the inner box (3) similarly to the said Example, and it uses a screw (28). The rail reinforcing plate (32) is then fixed by foaming and filling the gap between the inner box (3), the outer box (2) and the vertical partition wall (6 ') with a heat insulating material (4). It is embedded and fixed in the heat insulating material (4).

  Also in the above, when one of the plurality of slide rails (16 ′) attached to the rail reinforcing plate (32) is located at the lowermost part of the storage chamber, the same support member (19 ′) or support frame as described above is used. Can be secured and pulled out with the door.

  In the above embodiment, the rail reinforcing plate (32) has a substantially S-shaped cross section. However, the present invention is not limited to this, and various cross-sectional shapes such as an inverted U-shaped or H-shaped cross section can be used. Needless to say, a plurality of slide rails (16 ') may be attached to each chamber instead of one.

  According to the above configuration, the inner boxes (3) and (3 ') separated from each other on the left and right can be positioned and the heat insulation thickness dimension between them can be surely maintained, and the left and right inner boxes (3) ( 3 ') can maintain the vertical and front / rear positions of the cabinet to improve the rigidity of the cabinet, and the rail reinforcement plate (32) is embedded in the heat insulating material (4), so that the slide rail (16' ) (31) mounting strength can be further improved.

  In addition, in each said Example, although demonstrated with the example of the drawer-type container in the refrigerator compartment (11) of a horizontally long type refrigerator, not only this but a refrigerator may be a vertically long type, and the target storage room is vegetables. Needless to say, the present invention can also be applied to a structure of a drawer type container of another storage room such as the room (7) or the freezing room (13).
