Further, a support roller 69 is pivotally supported at a corner on the upper front side of the mounting surface 67A. In other words, the arrangement position of the support roller 69 is slightly in front of the front edge of the fixed rail 60 and slightly above the upper surface of the fixed rail 60.

  Next, the drawer 70 will be described. As shown in FIG. 7, the drawer 70 has a structure in which a frame body 80 that can accommodate the hotel pan 1 from the upper surface is extended on the back surface side of the door 71 that opens and closes the entrance 22 of the storage chamber 23. . As shown in FIGS. 9 and 10, the hotel pan 1 has a shape in which a flange 3 extends over the entire periphery of the upper surface opening of a pan body 2 having a substantially rectangular flat plate shape.

  The door 71 is heat-insulating, and the front shape capable of opening and closing the entrance / exit 22 of the storage chamber 23 from the front is a horizontally long rectangle and is formed thick. A handle 72 is provided on the surface of the heat insulating door 71, and a rectangular frame packing 73 is attached to the periphery of the back surface so as to be in close contact with the front edge of the entrance / exit 22.

As shown in FIG. 4 in detail, the bulging portion 74 is formed in a central region on the back surface of the heat insulating door 71, in a rectangular region that is slightly smaller than the opening of the doorway 22. Specifically, the bulging portion 74 has a structure in which a concave surface 76 is formed inside a square-shaped peripheral wall 75. In the central region of the concave surface 76 in the width direction, five illustrated vertical ribs 77 having the same height as the peripheral wall 75 are provided between the upper side 75A and the lower side 75B of the peripheral wall 75 at a predetermined interval in the horizontal direction. It is formed over. The distance between the vertical ribs 77 is such that two fingers of a hand can enter.
The left and right end portions of the concave surface 76 serve as attachment surfaces 78 for attaching the frame body 80.

The frame body 80 is formed to have a planar U shape in which the rear edges of the pair of left and right side frames 81 are connected by a back frame 85. The side frame 81 is formed in a belt-like shape having a vertical width almost equal to the depth of the hotel pan 1 and a length slightly shorter than the depth of the storage chamber 23. As shown in FIG. 1 is arranged with an interval comparable to the width of the upper end of the bread body 2 in 1. On the upper edge of each side frame 81, a mounting plate 82 having an L-shaped cross section for mounting the left and right flanges 3 of the hotel pan 1 is formed to project outward.
In addition, a mounting plate 83 is formed at the front edge of each side frame 81 so as to be bent at a right angle inside. A predetermined dimension at the end on the near side of the mounting plate 82, in other words, a dimension comparable to the depth of the concave surface 76 of the bulging portion 74 is cut away to allow the peripheral wall 75 to escape (escape portion 84).

  The rear frame 85 is formed by bending a reinforcing plate 87 having the same vertical width as that of the side frame 81 at the rear edge of the wide mounting plate 86, and is formed from the rear edges of the left and right side frames 81. Also, at a predetermined position slightly ahead, the mounting plates 82 and 86 are placed between the side frames 81 and fixed in a posture where the mounting plates 82 and 86 are flush with each other. As shown in FIG. 10, a reinforcing portion 86 </ b> A that is bent downward at a right angle is formed on the front edge of the mounting plate 86.

  In the frame body 80 assembled in this way, the mounting plate 83 at the front edge of the both side frames 81 is fixed to the corresponding mounting surface 78 provided in the bulging portion 74 on the back surface of the door 71. More specifically, the upper surface of the frame body 80 is lowered to a position where a predetermined dimension is lowered from the upper side 75A of the peripheral wall 75 on the back surface of the door 71, that is, the finger of the hand enters between the upper side 75A of the peripheral wall 75. As shown above, the two mounting plates 83 are brought into contact with the corresponding mounting surfaces 78 in the posture in which they are in position, and are attached through two bolts 88 to the insertion holes 83A of the mounting plate 83, as shown in FIG. The nut 88A embedded in the surface 78 is screwed and tightened to be fixed. Here, as shown in FIG. 8, the insertion hole 83A of the attachment plate 83 is formed as a horizontally long slot so that the horizontal attachment position of the frame body 80 can be finely adjusted.

  In the state where the frame body 80 is attached to the back surface of the door 71 as described above, the dimension between the vertical rib 77 on the back surface of the door 71 and the front edge of the mounting plate 86 of the back frame 85 is shown in FIG. As shown, the hotel pan 1 is fitted in the frame body 80 and the front flange 3 is in contact with the vertical rib 77. It is the dimension which can be mounted and supported by the edge.

The left and right side frames 81 constituting the frame body 80 are pivotally supported by the guide rollers 89 described above on the outer surface of the lower position at the projecting end on the back side.
On the other hand, a movable rail 90 on which the support roller 69 on the storage chamber 23 side rolls is provided at an upper position on the outer surface of the left and right side frames 81. The movable rail 90 is disposed from the front edge of the side frame 81 to a position slightly ahead of the rear edge, and has, for example, a shape in which a groove plate having a chevron-shaped cross section is provided on the upper edge of the vertical plate. 69 can roll along the lower surface of the groove plate.
As shown in FIG. 5, the predetermined region at the end portion on the near side of the movable rail 90 is an inclined portion 90 </ b> A having a gentle upward slope (less than 10 °) toward the near side. Further, on the back side of the movable rail 90, there is provided a stopper 91 having a tapering shape that descends toward the back.

Next, the operation of this embodiment will be described.
Each drawer 70 accommodates a defined hotel pan 1. Specifically, the hotel pan 1 is fitted from the upper surface side into a frame body 80 extending on the back surface of the door 71, and the left and right and rear edge flanges 3 are mounted on the left and right mounting plates 82 and the rear mounting plate. It is supported in a state of being placed on the plate 86.
When the drawer 70 is mounted in the storage chamber 23, the back end side thereof is inserted into the corresponding entrance / exit 22, and the drawer 70 is used while utilizing the cut-out portion 61 at the front end of the fixed rail 60 and the back side of the movable rail 90. The guide roller 89 is fitted to the front end of the fixed rail 60 on the storage chamber 23 side, and the support roller 69 on the storage chamber 23 side is fitted to the movable rail 90 of the drawer 70 to be supported.

  When the door 71 is pushed, as shown in the upper part of FIG. 5, the guide roller 89 rolls along the fixed rail 60 and the support roller 69 rolls along the movable rail 90, while the drawer 70 enters the storage chamber 23. Finally, as shown in the lower part of FIG. 4, the door 71 closes the entrance / exit 22 while the packing 73 is in close contact with the rim on the surface side of the entrance / exit 22. Here, the hotel pan 1 fits tightly between the left and right side frames 81 in the frame body 80 in the width direction, and in the length direction, the flange 3 on the front side and the back surface of the bread body 2 are connected to the door. 71 is accommodated between the vertical ribs 77 on the back surface of 71 and the front edge of the back frame 85 in the frame body 80, so that when the drawer 70 is pushed in (the same applies to the case described later). The rattling of the hotel pan 1 in the frame body 80 is suppressed as much as possible.

At the end of the push-in of the drawer 70, the guide roller 89 enters the inclined portion 60A at the back end of the fixed rail 60, and the support roller 69 enters the inclined portion 90A at the front end of the movable rail 90. Thus, a force in a direction in which the drawer 70 is pushed by its own weight acts on the drawer 70 using the inclination. Therefore, even if the force for pushing the drawer 70 is weak, the drawer 70 is pushed to the normal position and the entrance 22 is closed.
On the contrary, if the drawer 70 is pushed in vigorously, there is a possibility that the drawer 70 will rebound after being pushed in. At this time, the inclined sections 60A and 90A of the fixed rail 60 and the movable rail 90 cause the corresponding guide roller 89 and support roller 69 to run backward. It functions to regulate and prevents unnecessary rebound of the drawer 70.

At the time of the cooling operation, as described above, the cold air generated by the in-compartment air sucked from the suction port 27 passing through the cooler 26 is blown into the upper outlet 28 on the left side surface of the refrigerator compartment 20, Furthermore, it is blown out from the two outlets 28 and the right end opening of the blowing duct 32 and circulated and circulated in the refrigerator compartment 20, that is, all the storage compartments 23, so that stored items such as food stored in the hotel pan 1 are stored. Stored refrigerated.
Here, in the hotel pan 1, the left and right, the back, and the flange 3 touch the mounting plates 82 and 86 of the frame body 80, and the front flange 3 can hit the back surface (the bulging portion 74) of the door 71. Therefore, it can be said that cold air is difficult to circulate between the peripheral edge of the hotel pan 1 and the frame body 80.

  However, in this embodiment, the bulging portion 74 on the back surface of the door 71 has a shape in which five vertical ribs 77 are formed at intervals in a rectangular peripheral wall 75, and the hotel pan 1 is tentatively closest to the front side. Even when the front flange 3 is in contact with the back surface of the door 71, it contacts over the longitudinal ribs 77 arranged in the lateral direction at a position lower than the upper side 75 </ b> A of the peripheral wall 75 by a predetermined dimension. It becomes a state. Therefore, as shown in FIG. 11, there is a gap between the flange 3 in front of the hotel pan 1 and the back surface of the door 71 at a position between adjacent vertical ribs 77 and at a position outside the vertical ribs 77 at both ends. s is configured, and the cold air circulates with the gap s as a circulation space, thereby contributing to the promotion of cooling, particularly on the back side of the door 71. Since this portion is close to the outside of the room and is relatively easy to raise the temperature, it is effective for cooling the inside of the refrigerator compartment 20 evenly.

  When the drawer 70 is pulled out, the guide roller 89 and the support roller 69 are fixed as shown in the upper part of FIG. 5 when the drawer 72 is pulled forward from the state shown in the lower part of FIG. The drawer 70 is pulled out along the rail 60 and the movable rail 90 while rolling in the reverse direction. The guide roller 89 and the supporting roller 69 ride on the corresponding fixed rail 60 and the inclined portions 60A and 90A of the movable rail 90 in the initial operation of the drawer, but the inclination is relatively gentle at less than 10 ° C. Therefore, it can be pulled out smoothly without much resistance. When the drawer 70 is pulled out appropriately, the stored item can be taken in and out of the hotel bread 1.

As shown in the lower part of FIG. 5, the drawer 70 is pulled out when the support roller 69 hits a stopper 91 provided on the back side of the fixed rail 60, and the drawer 70 is pulled out to the maximum.
In the present embodiment, when the drawer 70 is pulled out to the maximum, the distance L between the support roller 69 and the guide roller 89 is relatively large. Compared with the case where the distance is small, when the load from above as shown by the arrow P acts on the drawer 70, the load on each of the rollers 69 and 89 can be kept small, and the durability is improved. Figured.

When removing the hotel pan 1 from the frame body 80 of the drawer 70, for example, by cleaning the inside of the hotel pan 1, after pulling out the drawer 70 to the maximum as described above, the hotel pan 1 is emptied and removed from the frame body 80. . At this time, even if the hotel pan 1 is positioned on the near side and the front flange 3 hits the back surface (bulged portion 74) of the door 71 or is in a very close state, as described above, Since a gap s enough to allow two fingers to enter between the ribs 77 is secured, the hotel pan 1 is slid to the back while pushing the front flange 3 while putting the finger in the gap s, and the front and rear gaps are wide. At this point, the hotel pan 1 is framed by pulling the hotel pan 1 diagonally upwards by picking the flange 3 and lifting the front side, and then attaching the other hand to the side flange 3. It can be removed from the body 80.
The removal operation can be performed in the same manner even if a small amount of storage is left in the hotel pan 1.

  It should be noted that the position of the guide roller 89, the support roller 69, and the corresponding rails 60, 90 are not aligned due to assembly errors during manufacturing, which may hinder smooth insertion and removal of the drawer 70. In this embodiment, when attaching the frame body 80 to the attachment surface 78 on the back surface of the door 71, an insertion hole 83 </ b> A of a bolt 88 made of a horizontally long slot is formed in the attachment plate 83, and the frame body 80 is moved in the lateral direction. Since the position can be adjusted, it can be mounted relatively easily on the user side as well as before shipment at the factory.

  As described above, according to the present embodiment, in the structure of the portion in which the hotel pan 1 is accommodated in the frame body 80 of the drawer 70, the left and right and back flanges 3 of the hotel pan 1 are While placing on the mounting plates 82 and 86, the front flange 3 is made to face the back surface (bulged portion 74) of the door 71, and the bulged portion 74 is 5 in the rectangular peripheral wall 75. The vertical ribs 77 of the book are formed so as to be spaced from each other (about two fingers can be inserted), and the flange 3 in front of the hotel pan 1 is lowered from the upper side 75A of the peripheral wall 75 by a predetermined dimension (to the extent that the fingers can enter). It is supported in a form facing the vertical rib 77 at the above position. Therefore, even if the hotel pan 1 is located on the near side and the front flange 3 hits the vertical rib 77 or is very close, the gap s between which at least two fingers enter between the adjacent vertical ribs 77 Therefore, the flange 3, that is, the front side of the hotel pan 1 can be obtained by putting a finger in the gap s and hooking it on the front flange 3 or by pushing the flange 3 inward to widen the front and rear gaps. The hotel pan 1 can be easily detached from the frame body 80 by continuing to pull it out.

On the other hand, in the state in which the drawer 70 is stored in the storage chamber 23, the gap s described above is ensured between the flange 3 in front of the hotel pan 1 and the back surface (the bulging portion 74) of the door 71. Since the cold air sent to the refrigerator compartment 20 can circulate through the gap s, the circulation of the cold air in the refrigerator compartment 20 is promoted and the cooling capacity can be improved.
Moreover, since the above-mentioned gap s is formed between the vertical ribs 77 and the gap s functions as a vertically long distribution guide, the cold air circulation is further promoted.

The hotel pan 1 fits tightly between the left and right side frames 81 of the frame body 80 in the width direction, and in the length direction, the flange 3 on the front side and the back surface of the pan body 2 are the back surface of the door 71. When the drawer 70 is opened and closed (drawn or pushed in), the hotel pan 1 is attached to the frame when the drawer 70 is held between the vertical ribs 77 and the front edge of the back frame 85 in the frame 80. Shaking in the body 80 is suppressed as much as possible.
Further, when the drawer 70 is opened and closed vigorously, the flange 3 in front of the hotel pan 1 may hit the vertical ribs 77 due to inertial force. However, five vertical ribs 77 are provided, and each vertical rib 77 is provided. Since the load is distributed to 77, it is difficult to damage the load.

  In addition, as shown in the conventional example, the housing part that houses the hotel pan 1 is compared with the one that is formed as a rectangular frame by rounding a strip having a predetermined width in a horizontal plane. In the embodiment, the frame body 80 itself can be formed in a small size by eliminating the frame side on the near side, and in the case of cleaning, a difficult-to-wipe portion such as the back surface of the band material is wiped over a wide range. Since it is not necessary, it can be easily cleaned.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
(1) The number of vertical ribs, which is an example of the gap component, and the size of the gap associated therewith are not limited to those exemplified in the above embodiment, and can be arbitrarily set. If the number of vertical ribs is small and the width of the gap is large, it will be easier to put fingers in the hand. Conversely, if the number of vertical ribs is large and the width of the gap is small, the load will be greater when the hotel pan flange is hit. And is more effective as a cold air distribution guide.
(2) In the above embodiment, if the upper side of the peripheral wall provided on the bulging portion on the back surface of the door is removed, the upper part of the gap between the vertical ribs will open, so that the fingers of the hand can be inserted more easily. As a result, the circulation of cold air becomes smoother. Further, there may be no peripheral wall, and the vertical ribs may be formed so as to protrude on the plane at intervals.

(3) Further, the form of the gap constituting part is not limited to the vertical ribs exemplified in the above embodiment, but a mere protrusion or the like, in summary, a flange on the front side of the hotel pan is applied, and the rear surface of the door and the front flange Any other form may be used as long as a predetermined gap can be formed between the two.
(4) Although the horizontal refrigerator provided with six drawers was illustrated in the above embodiment, the number of drawers is arbitrary, and further, a vertical drawer refrigerator, a horizontal or vertical drawer freezer, and the same drawer The present invention can be widely applied to cooling refrigerators having a drawer that can be pulled out, such as a refrigerator with a refrigerator, and a drawer that is only partially used.
(5) The present invention is not limited to the hotel pan illustrated in the above embodiment, and can be similarly applied to a configuration in which a container with a flange having a top opening that is not standardized is accommodated in a drawer.
