The fixing method of at least one location is a hooking method comprising the hook-shaped portion 231 and the rectangular hole 286, so that the door frame 205 can be easily attached to and detached from the top rail 203.

  Note that the hook-shaped portion 231 and the fixing hole 232 may be provided on the side surface of the top rail 203, and the rectangular hole 286 and the round hole 287 may be provided on the side surface portion 283 and the main body portion 284.

  FIG. 6 is a sectional view showing the rail device and the container of the refrigerator in the first embodiment of the present invention. In FIG. 6, the vegetable compartment 103 which is the lowest storage compartment among the drawer-type storage compartments will be described as an example.

  First, the rail device 202 will be described.

  The cross-sectional shape perpendicular to the longitudinal direction of the cabinet rail 222 is not symmetrical, and the side surface having the higher height is fixed to the inner surface of the inner box 110.

  The middle rail 221 has a I-shaped cross section and a shape having flanges protruding left and right in the vertical direction. The lower flange of the upper and lower flanges is held by the cabinet rail 222 so as to be movable in the longitudinal direction.

  The top rail 203 has a U-shaped cross section, and holds the flange on the middle rail 221 so as to be movable in the longitudinal direction.

  Each of the cabinet rail 222 and the top rail 203 holds a plurality of rotation support members 145 by a rotation support member holding portion 146, and the middle rail 221 is movably held by the rotation support member 145. As the rotation support member 145, a bearing can be used.

  More specifically, the cabinet rail 222 holds the center of the upper and lower flanges of the middle rail 221 from the three directions via the plurality of rotation support members 145.

  Further, the top rail 203 holds the center rail 221 centered on the upper flange from three directions via a plurality of rotation support members 145.

  By combining the cabinet rail 222, the middle rail 221 and the top rail 203 in this way, the middle rail 221 can move in the longitudinal direction on the cabinet rail 222. Further, the top rail 203 is movable on the middle rail 221 in the longitudinal direction. That is, the top rail 203 can move in the longitudinal direction on the cabinet rail 222 via the middle rail 221.

  Further, the middle rail 221 and the top rail 203 can move smoothly as the plurality of rotation support members 145 rotate.

  The top rail 203, the middle rail 221, the cabinet rail 222, and the rotation support member 145 are attached to the inner box 110 in a state of being assembled in advance.

  Thereby, the maximum pull-out distance of the drawer door 201 becomes a length that allows the container 206 to be completely opened. That is, when the vegetable compartment 103 is fully opened, the rear end of the container 206 is positioned in front of the front surface of the drawer door 201 directly above the vegetable compartment 103. For this reason, it is easy to store food in the back of the container 206 and take out food from the back. Further, since the container 206 does not interfere with the upper drawer door 201, the container 206 can be easily attached and detached.

  Next, attachment of the rail device 202 to the inner box 110 will be described.

As shown in FIG. 6, a rail mounting portion 223 formed integrally with the cabinet rail 222 is disposed so as to come into contact with the side of the inner box 110 and fixed to the side of the inner box 110 with screws 400. .

  At this time, since the inner box 110 serving as a mounting surface is mainly molded from resin, even if screws are directly fixed to the inner box 110, it is impossible to secure a strength that can withstand the load applied to the rail device 202. Therefore, as means for securely fixing the rail device 202, the rail attachment portion 223 is attached to the rail holding member 280 embedded in the heat insulating material 111 via the inner box 110.

  The rail holding member 280 is mainly formed of a metal material such as iron. Further, by fixing the rail holding member 280 in advance to a predetermined position on the inner surface of the inner box 110, and then filling the space between the inner box 110 and the outer box 112 with the foam heat insulating material and burying it in the heat insulating material 111, The holding force of the rail holding member 280 can be further improved.

  The rail holding member 280 includes a rail holding portion 280a fixed with the rail attachment portion 223 and the screw 400, and an inward fall prevention means 280b for preventing the inner fall of the rail device 202. The rail holding portion 280a is formed of a substantially L-shaped vertical flange portion and a horizontal flange portion, and is in close contact with the side surface portion and the bottom surface portion of the inner box 110. The inward fall prevention means 280b is integrally formed with a horizontal flange portion that is a bottom surface portion of the rail holding portion 280a, and is formed as a lower flange portion that is directed downward in a direction away from the inner box 110.

  Since the inward fall prevention means 280b is a lower flange portion that faces downward and is embedded in the heat insulating material 111, even if a moment acts on the rail mounting portion 223 in the direction of falling into the vegetable compartment, the inner portion of the lower flange portion Since the fall prevention means 280b is blocked by the heat insulating material 111 filled in the lower part thereof, the fall prevention unit 280b can be prevented from falling down, and the strength of the rail holding member 280 can be further secured, and the inside of the rail device 202 in the vegetable compartment 103 is directed toward the inside of the cabinet. Can be prevented.

  In addition, the bottom wall 401 of the vegetable compartment 103 is formed with bottom surface step portions 401a on both sides, and the bottom surface step portion 401a is formed one step higher than the central portion serving as the reference surface of the bottom wall 401 and is formed in the depth direction. Yes.

  And the rail apparatus 202 is arrange | positioned on the bottom face level difference part 401a. Further, a side stepped portion 110a is formed on the side wall surface portion of the inner box 110 to which the rail device 202 is fixed. The side stepped portion 110 a is formed so as to be recessed toward the outer box 112 than the upper side wall surface portion in the vegetable compartment 103, and the wall thickness is thin.

  The rail mounting portion 223 is fixed to the side surface with a metal rail holding member 280 and a screw 400 with the side surface stepped portion 110a interposed therebetween.

  Accordingly, since the rail device 202 is placed on the bottom surface step portion 401 a and fixed to the side surface step portion 110 a with screws, the rail device 202 jumping out into the storage space can be suppressed, and the full width of the container 206 in the vegetable compartment 103. The dimensions can be increased and the invalid space can be reduced.

  Further, since the rail device 202 is assembled by being placed on the bottom surface step 401a, workability can be improved. Furthermore, since the wall thickness of the bottom wall 401 is increased at the bottom step 401a, heat insulation can be ensured.

  Moreover, the drawer door 201 of the lowermost vegetable compartment 103 is below the drawer door 201 of the upper freezer compartment 104, and when the user pulls out the drawer door 201, the position of the lowermost vegetable compartment 103 of the vegetable compartment 103 is positioned. Since it is in a position where it is easy to put weight on the drawer door 201, there is a high possibility that an external load amount is applied in addition to the load of the storage amount.

  However, since the rail holding member 280 is integrally formed with the substantially L-shaped rail holding portion 280a and the inward fall prevention means 280b that becomes the lower flange portion, as a prevention of the rail device 202 of the lowermost drawer door 201 from falling down, It can be kept stronger.

  Since the side wall thickness of the freezer compartment 104 and the vegetable compartment 103 is reduced by the side stepped portion 110a, a vacuum heat insulating material (not shown) is made to correspond to the portion where the rail device 202 is disposed. Heat insulation can be secured by attaching a vacuum heat insulating material having a height dimension larger than that between the rail device 202 of the freezer compartment 104 and the vegetable compartment 103 to the outer box 112.

  Next, the container 206 will be described in more detail. The container 206 is a container for storing beverages, frozen foods, and the like filled in vegetables and PET bottles, and is a resin box having an upper surface opened. The container 206 includes a narrow portion 261 having a narrow width so that step portions 262 facing inward are formed at both ends of the lower portion. The container 206 is supported by the rail device 202 via the door frame 205 by arranging the narrow portion 261 between the two rail devices 202 and placing the step 262 on the upper surface of the door frame 205. Is done.

  Thus, since the rail apparatus 202 is provided in the both corners of the lower part of the drawer door 201, it becomes possible to keep the narrow width part 261 in which the width | variety must be narrowed among the containers 206 as short as possible. Therefore, the container 206 can adopt a shape that makes the storage volume as large as possible.

  Further, on the side surface of the container 206, a plate-shaped side fin portion 266 that is elongated in the front-rear direction (depth direction) is provided below the central portion of the container 206 in the vertical direction. The side fin portions 266 protrude downward from both ends of the step portion 262 so as to extend downward the plane of the side surface of the container 206. Further, the side fin portion 266 covers the side surface of the horizontal portion 231 b of the flange-shaped portion 231 that protrudes from the upper surface portion 282 of the door frame 205. Thereby, it is possible to cover the rectangular hole 286, the hook-shaped portion 231 and the screw with a simple configuration, and it is possible to prevent the hand and the finger from being damaged by these, and the safety is improved. In addition, since the rectangular hole 286, the hook-shaped portion 231 and the screw are difficult to see, the appearance design can be improved.

  The container 206 will be described in more detail with reference to FIGS. 7 and 8 are a side view and a rear view of the refrigerator container according to Embodiment 1 of the present invention.

  As shown in FIGS. 7 and 8, the container 206 includes a flange portion that protrudes outward around the opening. That is, a front flange portion 206a is provided at the upper end portion of the front surface, a side flange portion 206b is provided at the upper end portions of both side surfaces, and a rear flange portion 206c is provided at the upper end portion of the rear surface. The flange portion is formed so that the side walls of the front surface, the side surface, and the back surface are folded back, and the inside of the flange portion is desirably hollow in terms of weight reduction. By providing this flange portion, the strength of the opening of the container 206 can be increased.

  A front protrusion 206e protruding forward from the container 206 is provided at a position corresponding to the inner surface recess 302 on the front flange portion 206a located in front of the container 206.

  Moreover, the wall surface height of the back surface of the container 206 is configured to be lower than the wall surface height of the front surface or both side surfaces. In other words, the back flange portion 206c is provided at a position lower than the front flange portion 206a and / or the side flange portion 206b.

A step 262 provided at the lower part of both side surfaces of the container 206 is provided with a lower protrusion 206d integrally formed with the container 206 and protruding downward and forward and / or rearward. As a result, the moment applied to the mounting portion is reduced by setting the position serving as the fulcrum of the pulling force behind the drawer door 201, so that the mounting portion of the top rail 203 or the mounting portion of the rail fixing portion is protected from damage. It becomes possible.

  Further, the lower protrusion 206d is covered with a side fin 266.

  The attachment of the container 206 to the door frame 205 will be described with reference to FIG. FIG. 9 is a side view illustrating the positional relationship between the drawer door, door frame, and container of the refrigerator according to Embodiment 1 of the present invention.

  As shown in FIG. 9, the container 206 can be connected to the drawer door 201 by inserting the front protrusion 206 e provided in front of the container 206 into the inner surface recess 302 provided in the inner plate 211.

  The front protrusion 206e is formed of a vertical portion that rises substantially perpendicular to the front flange portion 206a, and a horizontal portion that is bent upward from the vertical portion so as to be substantially horizontal to the front flange portion 206a. The inner surface recess 302 is formed of a vertical portion that is recessed substantially perpendicular to the inner plate 211 and a horizontal portion that is bent upward from the vertical portion so as to be substantially horizontal to the inner plate 211. It is desirable to ensure the connection of the container 206 to the drawer door 201.

  The inner surface recess 302 has a size that allows the front protrusion 206e to be inserted. The upper end of the inner surface recess 302 is inserted between the vertical portion of the front protrusion 206e and the front flange portion 206a. It is desirable that the insertion portion 303 is provided in order to more reliably connect the container 206 to the drawer door 201. Further, the lower protrusion 206 d of the container 206 is inserted into a notch-shaped fixing hole (not shown) formed in the door frame 205. Thereby, the container 206 can be fixed to the door frame 205.

  Next, a method for attaching the container 206 will be described. First, the rear of the container 206 is slightly lifted, and the vertical portion of the front protrusion 206e is inserted into the inner surface recess 302 avoiding the upper end insertion portion 303. Thereafter, the container 206 is leveled. As a result, the upper end insertion portion 303 is inserted between the vertical portion of the front projection 206e and the front flange portion 206a, and the lower projection 206d is inserted into the fixing hole of the door frame 205.

  As described above, in the present embodiment, by fixing the container 206 and the drawer door 201, the force caused by the moment to rotate the drawer door 201 in the direction of tilting forward can be reduced. It is possible to prevent the device 202 from being deformed. In addition, a force to lift the front portion of the container 206 generated by a moment to rotate the drawer door 201 in the direction to tilt forward is provided on the drawer door 201 via the front protrusion 206e. By receiving the upper surface of the inner surface recess 302, the container 206 can be prevented from floating upward.

  Further, although the front projection 206e is a convex portion, it is made of resin as in the case of the container 206, and the inner surface concave portion 302 is a concave portion, so that metal parts do not protrude from the drawer door 201 and the container 206. , Safety in use, visual quality will not be lost. Moreover, since metal parts do not appear in the vegetable compartment 103, metal parts do not condense.

  Further, the front protrusions 206e are provided on the left and right sides of the container 206, and the inner plate 211 of the drawer door 201 is only provided with recesses on the left and right sides, so that the cooling that flows along the inner plate 211 is performed. The air path resistance of the cold air does not increase and the cold air can be circulated without waste, so that an energy saving operation can be realized.

  Further, by covering the fixing portion of the top rail 203 and the door frame 205 with the side fin portion 266, it is possible to prevent the hand and fingers from being damaged by the fixing portion with a simple configuration, and thus safety is improved. In addition, when the drawer door 201 is opened, the fixed portion becomes difficult to see, so that the appearance design can be improved.

  Further, by providing the side fin portion 266 below the central portion in the vertical direction of the container 206, most of the side surface of the container 206 has a flat shape with no irregularities. Thereby, the air path resistance of the cooling cold air flowing from the front to the rear along the side surface of the container 206 can be reduced. As a result, the input of a cooling fan (not shown) can be reduced, and energy saving of the refrigerator can be achieved. Further, the design is improved because the side surface is flat.

  Furthermore, when the container 206 is pulled out together with the drawer door 201, the outflow of the cold air inside the container 206 to the outside of the container 206, that is, outside the vegetable compartment 103 can be reduced, and energy saving of the refrigerator can be achieved.

  Furthermore, since the container 206 is held at the bottom by the door frame 205, the rail device 202 does not divide the space on the side of the container 206 in the vertical direction, and condensation and frost formation due to a temperature difference between the upper and lower sides and convection accumulation are prevented. It does not occur.

  In the present embodiment, the container housed in the vegetable compartment 103 has been described. However, the same effect can be obtained even in the container housed in the freezer compartment 104.

  As described above, since the refrigerator according to the present invention can secure a wide actual storage space, it can be used for a refrigerator having a drawer-type storage room, and further, such as a unit kitchen equipped with a drawer. It can also be developed in fields that require design design.
