Description

  The present invention relates to a refrigerator, and relates to a refrigerator including two side-by-side storage rooms.

  Conventionally, a refrigerator includes a plurality of storage rooms such as a refrigerator compartment, a freezer compartment, and a vegetable compartment. It is also common that a plurality of storage rooms are provided side by side at the same height in the cabinet.

  For example, there is a refrigerator in which an ice making room and a switching room are provided side by side. The switching room is a storage room whose indoor temperature can be changed.

  In such a refrigerator, the ice making room and the switching room are generally provided as a drawer-type storage room.

  Specifically, a center rail is provided between the containers forming the ice making chamber and the switching chamber. In addition, side rails are provided on both sides of these two containers. The ice making chamber and the switching chamber can be pulled out independently by the center rail and the side rail.

  Here, the two side rails are integrally formed on a horizontal partition wall (horizontal partition wall) that insulates between the ice making room and the switching room and the vegetable room disposed below them.

  Further, the center rail is provided by being integrally molded with a vertical partition wall (vertical partition wall) attached on the horizontal partition wall. The vertical partition wall having the center rail insulates the left and right spaces, that is, the ice making chamber and the switching chamber.

  Here, in such a structure, a problem of non-parallel rails may occur.

  For example, when the installation position of the vertical partition wall deviates from the normal position, the longitudinal direction of the side rail and the longitudinal direction of the center rail are not parallel.

  This causes problems such as rattling when the ice making chamber and the switching chamber are taken in and out.

  Therefore, a technique for solving such a non-parallel problem of rails is also disclosed (for example, see Patent Document 1).

  FIG. 10 is a front view of a conventional refrigerator 100.

  A conventional refrigerator 100 shown in FIG. 10 includes a refrigerating room 101, an ice making room 102, a switching room 103, a vegetable room 104, and a freezing room 105 as storage rooms.

  FIG. 11 is a perspective view showing a partition structure of a conventional refrigerator 100.

  As shown in FIG. 11, the ice making chamber 102 and the switching chamber 103 provided adjacent to each other in the inner box 113 and the refrigeration chamber 101 disposed on these are partitioned by a horizontal partition wall 115.

  In addition, the ice making chamber 102 and the switching chamber 103 are separated from the vegetable chamber 104 arranged immediately below by a horizontal partition wall 107. Further, the ice making chamber 102 and the switching chamber 103 are partitioned by a vertical partition wall 108.

  Side rails 109 are integrally formed on the left and right ends of the horizontal partition wall 107. Further, the center rail 110 is also integrally molded.

By adopting such a configuration, the position of the two side rails 109 does not depend on the mounting position of the vertical partition wall 108. For this reason, even when the mounting position of the vertical partition wall 108 is deviated from the normal position, the play does not occur when the ice making chamber 102 and the switching chamber 103 are put in and out due to this deviation.
JP 2006-78057 A

  In the conventional refrigerator, the center rail 110 that supports one side of the drawer-type storage chamber is integrally formed with one side partition wall together with the side rail 109. Thereby, smoothness of taking in and out of the storage room is secured.

  However, there is a case where the side rail 109 and the center rail 110 cannot be integrally formed on one horizontal partition wall.

  For example, an ice making room and a switching room whose temperature can be changed in a low temperature zone are arranged side by side, and there may be a freezer room below the vegetable room as in the conventional refrigerator. .

  That is, a plurality of storage spaces adjacent in the vertical direction may be in the same temperature range. In this case, the cooling efficiency is better when heat insulation is not performed between the ice making room and the switching room and the freezing room.

  Therefore, it may be better not to install a horizontal partition wall that partitions the ice making room and the switching room and the freezing room.

  Therefore, it is not desirable to apply a method of integrally molding the side rail and the center rail to the horizontal partition wall in such a refrigerator.

  Moreover, when there is no horizontal partition wall, the side rail that exists as a single unit is attached to a predetermined position of the inner box.

  However, the inner box is usually produced by foam molding. Foam molding is generally difficult to mold with high accuracy. Therefore, it is difficult to accurately provide a groove or hole for attaching the side rail at a proper position.

However, it may be difficult to completely suppress the deformation of the inner box 70 by the foam pressing jig due to the component configuration in the warehouse and the convenience of the moving direction of the foam pressing jig. The foam insulating material 72 is deformed by the foaming pressure when foaming, and the inner box 70 swells to the front surface (inside the cabinet), and accordingly, the position of the decorative plate 45 attached to the inner box 70 is It will be pushed forward. The left and right ends of the decorative plate 45 are fixed, and the amount of deformation is relatively small near the left and right ends of the decorative plate 45, but the amount of deformation is relatively large near the center of the decorative plate 45. The mounting surface 46c of the rear end mounting portion 46 in the vicinity of the center portion has a large amount of deformation to the front surface (inside the warehouse). When the amount of deformation of the mounting surface 46c toward the front surface (inner side) increases, the rear end surface 20a of the rear end portion of the center rail 20 comes into contact with the mounting surface 46c of the rear end mounting portion 46, and the center rail 20 is moved. If the center rail 20 becomes difficult to insert from the side, the workability of attaching the center rail 20 is reduced, and the amount of deformation of the attachment surface 46c toward the front surface (inner side) increases, the center rail 20 may not be inserted.

  On the other hand, in this embodiment, a gap (dimension A) is provided between the rear end surface 20a of the rear end portion of the center rail 20 and the mounting surface 46c of the rear end mounting portion 46 of the decorative plate 45. ing.

  As a result, the inner box 70 is deformed by the foaming pressure when the foam heat insulating material 72 is foamed, and the inner box 70 is inflated to the front surface (inner side), and is attached to the inner box 70 accordingly. Even if the decorative plate 45 is deformed to the front surface (inner side), there is a gap (A between the rear end surface 20a of the rear end portion of the center rail 20 and the mounting surface 46c of the rear end mounting portion 46 of the decorative plate 45. Therefore, the center rail 20 can be easily inserted from the side, and the workability of attaching the center rail 20 is not lowered.

  The inventors have studied in detail the gap (A dimension) between the rear end surface 20a of the rear end portion of the center rail 20 and the mounting surface 46c of the rear end mounting portion 46 of the decorative plate 45. The following findings were obtained.

  Preferably, even when the deformation due to the foaming pressure of the inner box 70 can be surely suppressed by the jig, the mounting variation of the decorative plate to the inner box 70 due to the seal member or the like added to the decorative plate is preferable. Is a gap of at least 1 mm or more.

  Further, as described above, as described above, the inner box 70 is deformed by the foaming pressure when the foam heat insulating material 72 is foamed, and the inner box 70 is swollen to the front surface (inner side). Since the decorative plate 45 attached to the inner box 70 is pushed out to the front surface (inside of the cabinet), the inner case due to the foaming pressure and the gap considering the mounting variation due to the sealing member added to the decorative plate, etc. It is a gap of 3 mm or more that compensates for both the gap considering 70 deformation.

  As already described, the center rail 20 is fixed to the front end portion and the rear end portion by using the second fitting portion 11, the second convex portion 21, the claw 46a, and the guide 46b. That is, the center rail 20 is fixed without using screws or the like.

  Thereby, since the center rail 20 is fixed without using a screw or the like, a tool such as a screwdriver is not required, and the workability of the serviceman is improved. The storage room formed by the ice making chamber 54, the freezing chamber 55, and the freezing chamber 56 after the center rail 20 is removed becomes wide, and the storage chamber can be easily cleaned. Can be kept in a hygienic refrigerator.

  Further, in the case of a structure that allows the center rail 20 to be removed, a fitting portion such as a claw is provided on a plurality of parts such as the beam 10, the decorative plate 45, the horizontal partition wall 90, etc. However, as described above, the center rail 20 is fitted and fixed using the beam 10 as a reference for the mounting position, so that variations in the mounting position of the center rail 20 can be suppressed, and the operability in opening and closing the drawer door can be suppressed. Can be secured.

  FIG. 13 is a side view showing a state in which center rail 20 of the refrigerator according to Embodiment 1 of the present invention is attached.

  14 is a cross-sectional view of FIG. 13 taken along the line AA.

The relationship is such that the position of the rail 20 is pushed forward. As a result, the center rail 20 can be attached at a position along the beam 10 existing in the front, and as a result, the center rail 20 can be securely attached with the beam 10 even if there is no screw. It is possible to secure the operability of the door.

  In the embodiment of the present invention, the structure shown in FIGS. 13 and 14 is used. However, as long as the center rail 20 is pushed forward and fixed at the position of the beam 10 reference, the structure other than the structure shown in the present invention is used. It doesn't matter.

  The decorative plate 45 includes an attaching / detaching means (not shown) that allows the decorative plate 45 to be attached to and detached from the inner box 70, and the decorative plate 45 is attachable / detachable only by the attaching / detaching means without using a tool. is there.

  In this case, as described above, when the decorative plate 45 is removed after the center rail 20 is removed, a communication duct (not shown) that is integrated with the decorative plate 45 and supplies cold air from the refrigerator compartment to the vegetable compartment is provided. The service duct can be improved, and the communication duct is exposed, so even if liquid or foreign matter enters the communication duct from the refrigerator compartment or foreign matter or dirt adheres to the user, Oneself can clean the inside of the communication duct and improve the cleanability inside the communication duct.

  Furthermore, the relative position of the side rail 30 and the side rail 40 with the center rail 20 is constrained by fitting with the beam 10. Further, it is attached to the inner box 70 while maintaining this state.

  FIG. 8 is an enlarged perspective view showing a state where the side rail 40 and the beam 10 of the refrigerator in the present embodiment are fitted.

  In addition, the attachment structure of the side rail 40, the beam 10, and the inner box 70 etc. are mainly demonstrated using FIG. 8 and FIG. Since the side rail 30 has the same structure as that of the side rail 40, the description thereof will be omitted.

  As shown in FIG. 8, the first convex portion 41 of the side rail 40 is fitted into the hole that is the first fitting portion 12 at the right end portion of the beam 10. Further, the right end of the beam 10 is fixed to the right inner surface of the inner box 70.

  Further, the side rail 40 is attached to the right inner surface of the inner box 70 in a state of being fitted to the beam 10.

  Specifically, the side rail 40 has a protrusion 42 on the side surface, and is temporarily fixed to the inner box 70 by the protrusion 42 and then fixed to the inner box 70 by a screw 43.

  FIG. 9 is a diagram showing an outline of the attaching portion 70a provided on the inner side surface of the inner box 70 of the refrigerator in the present embodiment.

  FIG. 9A is a cross-sectional view showing the relationship between the side rail 40 and the groove 70b provided in the mounting portion 70a.

  As shown in FIG. 9A, the attachment portion 70a has a groove 70b in which the side surface of the side rail 40 is embedded.

  Further, the width in the height direction of the groove 70 b is wider than the width in the height direction of the side rail 40. The side rail 40 is temporarily fixed in the groove 70 b and then fixed by the screw 43.

  FIG. 9B is a diagram illustrating a relationship between the temporary fastening holes 70 c provided in the attachment portion 70 a and the protrusions 42 of the side rail 40.

  As shown in FIG. 9B, the dimension of the temporary fastening hole 70c is larger than the dimension of the cross section of the protrusion 42 parallel to the inner side surface of the inner box 70.

  The side rail 40 has another protrusion 42 at a position from the rear end. Further, the mounting portion 70 a has another temporary fastening hole 70 c at a position corresponding to the protrusion 42.

  The side rail 40 is temporarily fastened to the inner box 70 by hooking these two protrusions 42 to the temporary fastening holes 70c.

  As described above, the groove 70b and the temporary fastening hole 70c have a play that allows the side rail 40 to be attached to an arbitrary position within a predetermined range.

  Thereby, the side rail 40 in a state of being fitted to the beam 10 can be easily fixed at a position in the inner box 70 determined with the beam 10 as a reference.

  Similarly, the side rail 30 can be easily fixed at a position determined based on the beam 10.

  FIG. 15 is a detailed cross-sectional view showing an outline of an attachment portion provided on the inner surface of the inner box of the refrigerator in the first embodiment of the present invention.

  At least the vicinity of the tip of the protrusion 42 provided on the side rail 40 is embedded in the foam heat insulating material 72.

  Thereby, the protrusion 42 is fixed by the foam heat insulating material 72, and the strength of the side rail 40 supported so that the container forming the freezing chamber 55, which is the two drawer-type storage chambers provided side by side, is supported in a removable manner. Thus, the user of the refrigerator 51 puts in and out the drawer-type door 62 of the freezer compartment 55, which is the two drawer-type storage rooms provided side by side, with less backlash and more smoothly. be able to.

  Although the side rail 40 has been described here, the same applies to the side rail 30.

  FIG. 16 is a perspective view of relevant parts for explaining the outline of the ice making room, the freezing room, and the refrigerating room of the refrigerator according to Embodiment 1 of the present invention. Specifically, for the sake of explanation, the top plate of the horizontal partition wall 90 between the refrigerator compartment 53, the ice making chamber 54 and the freezing chamber 55 is removed, and the foam insulation 72 is provided on the horizontal partition wall 90. It is a principal part perspective view which is the state before filling, and shows the state which cut | disconnected the part of the horizontal partition wall 90 and the beam 10. FIG.

  Here, the horizontal partition wall 90 includes an upper plate (not shown) and a lower plate 90a. A grid-like rib 91 is provided at a location where the center rail 20 of the lower plate 90a is fixed.

  By the way, although this horizontal partition wall 90 is integrally formed with the foam heat insulating material 72, when it is integrally formed, the deformation of the horizontal partition wall 90 due to foaming pressure is suppressed by using a foam pressing jig. There are places where deformation due to foaming pressure cannot be completely suppressed due to reasons such as the configuration of the above and the moving direction of the jig. In the present embodiment, for example, in the rear cavity portion of the partition portion between the ice making chamber and the freezing chamber side by side, the foam pressing jig cannot be inserted from the front front direction of the inner box. The location where the center rail 20 is fixed is a location where the foam pressing jig is difficult to press.

  However, as in the present embodiment, the horizontal partition wall 90 is composed of an upper plate (not shown) and a lower plate 90a, and the lower plate 90a has a lattice-like shape at a position where the center rail 20 is fixed. By providing the rib 91, the strength of the portion where the center rail 20 of the lower plate 90a is fixed is improved, and the portion where the center rail 20 of the lower plate 90a is fixed without the foam pressing jig is In addition, it is possible to suppress the deformation due to the foaming pressure when the foam heat insulating material 72 is foamed, and as a result, the rattling of the inter-room rail fixing portion is suppressed, and the drawer type is provided side by side by providing a stronger fixation. The two storage rooms, the ice-making room drawer doors and the freezer drawer doors, have less rattling and can be taken in and out more smoothly. It is also possible to improve the strength.

  FIG. 17 is a main part explanatory view showing a state where the center rail and the horizontal partition wall of the refrigerator according to Embodiment 1 of the present invention are fitted. Specifically, for the purpose of explanation, it is a main part explanatory view showing a state in which the vicinity of the rear end portion of the center rail 20 and the horizontal partition wall 90 are fitted.

  Here, the lower plate 90a of the horizontal partition wall 90 includes a hook-like convex portion 92 that protrudes downward from the lower surface of the lower plate 90a, and the center rail 20 has a hook-like concave portion upward in the vicinity of the rear end portion. 100. The hook-shaped convex portion 92 and the hook-shaped concave portion 100 are fitted.

  Thereby, the position of the center rail 20 is restricted in the vertical direction with respect to the horizontal partition wall 90, and the user of the refrigerator 51 can store the two drawer-type storages provided side by side. The drawer-type door 61 of the ice making chamber 54 and the drawer-type door 62 of the freezing chamber 55, which are chambers, have less backlash in the vertical direction, and can be taken in and out more smoothly.

  Further, the lower plate 90a of the horizontal partition wall 90 includes a recess (not shown) in the lower plate 90a, and the center rail 20 includes a claw portion (not shown) in the vicinity of the rear end portion. ing. This recessed part and a nail | claw part are fitted.

  Thereby, the position of the center rail 20 is restricted in the left-right direction with respect to the horizontal partition wall 90, and the user of the refrigerator 51 uses the ice-making room 54, which is two drawer-type storage rooms provided side by side. The pull-out door 61 and the pull-out door 62 of the freezer compartment 55 have less backlash in the left-right direction and can be taken in and out more smoothly.

  As described above, the front end portions of the center rail 20, the side rail 30, and the side rail 40 are fitted to one beam 10.

  In other words, the left and right positions of the center rail 20, the side rail 30, and the side rail 40 are accurately determined by the beam 10.

  Furthermore, the beam 10, the center rail 20, the side rail 30, and the side rail 40 are attached to the inner box 70 in an integrated state.

  Specifically, the beam 10 is installed in a bridge shape from the left inner surface to the right inner surface in the inner box 70. During the installation, the rear end portion of the center rail 20 is fixed to the rear end attachment portion 46 of the decorative plate 45 attached to the inner surface of the inner box 70.

  Since the decorative board 45 is produced by injection molding, the positional accuracy of the nail | claw 46a etc. for fixing the said rear-end part with which the rear-end attachment part 46 was equipped is high.

  Further, the side rail 30 and the side rail 40 are attached to the inner box 70 with play in a state of being fitted to the beam 10.

  Here, the inner box 70 is produced by foam molding as described above. In addition, foam molding is generally difficult to perform with high precision. Therefore, it is difficult to accurately mold the side rails 30 and the grooves for attaching the side rails 40 at regular positions on the inner surface of the inner box 70.

  That is, when the side rail 30 and the side rail 40 are independently fixed to the inner box 70 with reference to the groove formed in the inner box 70, the side rail 30 and the side rail 40 are not parallel to the center rail 20. The problem is likely to occur.

  However, in the refrigerator 51 in the present embodiment, the positions of the center rail 20, the side rail 30, and the side rail 40 are determined in the refrigerator 51 with reference to the beam 10.

  That is, the side rail 30 and the side rail 40 are attached to the refrigerator 51 while maintaining high parallelism with the center rail 20.

  Thereby, the user of the refrigerator 51 can smoothly put in and out the ice making chamber 54 and the freezing chamber 55 supported by these rails.

  Therefore, the refrigerator 51 of the present embodiment is a refrigerator having two drawer-type storage chambers provided side by side, and even when a horizontal partition wall is not provided immediately below, the storage chambers can be taken in and out. It is a refrigerator that can ensure smoothness.

  The beam 10 is integrally formed with a foam heat insulating material 72 such as urethane, for example, and the foam 10 is filled with the foam heat insulating material 72 by foaming.

  Thereby, the heat transfer from the surroundings to the inside of the ice making chamber 54, the freezer compartment 55, and the freezer compartment 56 which are storage rooms will be suppressed, and the heat insulation effect will be improved.

  In addition, this improves the strength of the pull-out door 61 and the beam 10 that is the support portion of the door 62, and the user of the refrigerator 51 can make ice making as two side-by-side drawer-type storage rooms. The drawer-type door 61 of the chamber 54 and the drawer-type door 62 of the freezer compartment 55 have less rattling and can be taken in and out more smoothly. Furthermore, the load-proof strength of the drawer-type door 61 and the door 62 can be increased. Improvements can also be made.

  In this embodiment, the beam 10 is foam-filled with a foam insulation material 72 such as urethane, but from the viewpoint of workability during assembly and fluidity of the foam insulation material 72 such as urethane, polystyrene foam is used. May be placed inside the beam 10.

  By connecting the temperature zone of the storage chamber formed immediately below the beam 10 and the temperature zone of the two storage chambers to the same temperature zone without providing a partition wall that forms the bottom surface of the two storage chambers, Cooling of the storage chamber and two storage chambers formed directly under the beam by providing a beam at the height corresponding to the partition wall and arranging each rail with the beam as a reference, and having the same temperature range While improving efficiency, maintaining the parallelism between each rail at a high level can provide the refrigerator which can smoothly take in and out the two storage rooms.

  In addition, the storage room formed immediately below the beam 10 is a large-capacity freezing room, one of the two storage rooms is an ice making room, and the other is a small-capacity freezing room. Due to the freezing temperature zone, the freezing temperature zone storage room is consolidated, and a large-capacity freezing room, which is a storage room formed immediately below the beam 10, contains a large amount of frozen food to be stored for a long time. A small-capacity freezer room that is the other of the two storage rooms contains frozen foods that are frequently used daily, and an ice-making room that is one of the two storage rooms is frequently used daily. By putting ice, the user is easy to use. More specifically, frozen foods that are frequently used in daily life are placed in a small-capacity freezer that is the other of the two storage rooms, so that the burden on the user when opening the storage room can be reduced. Since the small-capacity freezer compartment is frequently opened and closed, the amount of power consumption can be reduced as compared to the frequent opening and closing of the large-capacity freezer compartment.

  In the refrigerator 51 of the present embodiment, it is assumed that the side-by-side ice making chamber 54 and freezing chamber 55 are not partitioned by a horizontal partition wall. In addition, the ice making chamber 54 and the freezing chamber 55 are supported by the center rail 20, the side rail 30, and the side rail 40 so as to be able to be taken in and out.

  However, the combination of these storage rooms is not limited to the above combination.

  For example, if two storage spaces arranged vertically are in the same temperature range, there is no need to provide a horizontal partition wall between them.

  Therefore, the present invention can be applied to the case where the upper storage space is divided into left and right of the two storage spaces of the same temperature range arranged vertically and each is provided in the refrigerator as a drawer-type storage chamber.

  Specifically, by supporting the two drawer-type storage chambers by the center rail 20, the side rail 30, and the side rail 40 that are fitted to the beam 10, the smoothness of the storage chambers can be improved. Secured.

  Further, when three or more storage chambers are provided side by side, the center rails 20 may be arranged in the longitudinal direction of the beam 10 and their front end portions may be fitted with the beam 10. Further, the decorative plate 45 may be provided with a claw 46a for attaching these rear ends.

  In the present embodiment, the side rails 30 and 40 are provided with the first convex portions 41 and the beams are provided with the first fitting portions 12, but the side rails 30 and 40 are provided with fitting portions. The beam may be provided with a convex portion.

  Further, in the present embodiment, the second rail 21 is provided on the space rail 20 and the second fitting portion 11 is provided on the beam. However, the space rail is provided with a fitting portion and the beam has a convex portion. May be provided.

  In the present embodiment, the protrusions 42 provided on the side rails and the temporary fastening holes 70C provided on the inner box are provided at two places, but at least one place may be provided, and three or more places may be provided.

  In the present embodiment, the two drawer-type storage chambers provided side by side in the inner box are the ice making chamber 54 and the freezing chamber 55, and the storage chamber formed immediately below the beam 10 is the freezing chamber. However, the two drawer-type storage rooms provided side by side in the inner box are two refrigeration rooms, or a refrigeration room and a chilled room, and the storage room formed immediately below the beam 10 is It is good also as a structure made into a refrigerator compartment.

  That is, the temperature zone of the storage chamber formed immediately below the beam and the temperature zone of the two storage chambers are made the same temperature zone, and the communication is made without providing a partition wall that forms the bottom surface of the two storage chambers. do it.

  Further, the center rail 20 is provided with slits (not shown) having an interval of a size that does not allow a finger to enter, for example.

  Thereby, even when the user puts his hand on the freezer compartment 55 side of the two drawer-type storage rooms provided side by side, the ice detection for detecting the amount of ice provided in the ice making room 54 The lever (not shown) or the like is not touched by hands, so that the user can be prevented from being injured and the safety can be maintained. In addition, although it was set as the slit here, you may make it a lattice form.

  In addition, when uncolored resin is used for the beam 10, the foam heat insulating material 72 with which the inside of the beam 10 is filled permeate | transmits, and an appearance deteriorates. Therefore, for example, by coloring the beam 10 white, the permeation of the foam heat insulating material 72 filled in the beam 10 is suppressed, the appearance can be improved, and the appearance quality is improved.

  The present invention is a refrigerator provided with two drawer-type storage chambers provided side by side, and even when a horizontal partition wall is not provided directly below, the smoothness of the storage chambers can be secured. A refrigerator can be provided. Therefore, the present invention can be applied to various types and sizes of refrigerators for home use and business use.
