  As shown in FIG. 3, the partition member 50 divides the freezer compartment 34 and the cooler compartment 62, and forms a cool air passage 50a therein. A cold air discharge duct 53 is provided integrally or separately with the partition member 50. The cool air discharge duct 53 communicates with the cool air passage 50 a and discharges cool air into the middle container 43. The cool air discharge duct 53 has a front end inside the middle container 43 disposed below the upper container 42 so as to face the inclined surface 42a of the upper container 42 and the discharged cold air is guided to the inclined surface 42a. A discharge port 53a of the cold air discharge duct is provided so as to enter.

  The position of the discharge port 53a of the cold air discharge duct 53 is such that the cold air discharged from the discharge port 53a does not flow around to the back side of the middle container 43 and is a flange formed behind the rear wall of the middle container 43. It is comprised so that it may become the front (compartment inner side) from the part rear wall 43c. That is, the distance dimension L5 between the discharge port 53a of the cool air discharge duct 53 and the flange rear wall 43c shown in FIG. 3 is set to be zero or more.

  Further, a cold air discharge duct 54 is provided integrally with or separately from the partition member 50. The cool air discharge duct 54 communicates with the cool air passage 50 a and discharges cool air into the lower container 44. The cool air discharge duct 54 has a front end inside the lower container 44 disposed opposite to the inclined surface 43a of the middle container 43 and disposed below the middle container 43 so that the discharged cold air is guided to the inclined surface 43a. A discharge port 54a of the cold air discharge duct 54 is provided so as to enter.

  The position of the discharge port 54a of the cool air discharge duct 54 is a flange formed on the rear side of the back wall of the lower container 44 so that the cool air discharged from the discharge port 54a does not flow around to the back side of the lower container 44. It is comprised so that it may become the front (compartment inner side) from the part rear wall 44c. That is, the distance dimension L6 between the discharge port 54a of the cold air discharge duct and the flange rear wall 44c shown in FIG. 3 is set to be zero or more.

  The distance dimension L4 between the discharge port 52a of the cool air discharge duct 52 that discharges cool air into the upper container 42 and the flange rear wall 42c formed behind the rear wall of the upper container 42 is set to be equal to or greater than zero. Thus, the cool air discharged from the discharge port 52a is configured not to flow around to the back side of the upper container 42. That is, the distance dimension L4 between the discharge port 52a of the cold air discharge duct 52 and the flange rear wall 42c shown in FIG. 3 is set to be zero or more.

  In the present embodiment, since it is configured as described above, the cold air discharged from the discharge ports 53a and 54a of the cold air discharge ducts 53 and 54 is guided to the inclined surfaces 42a and 43a, and the middle container 43 and the lower container 44. It is discharged inside. In this way, the inclined surfaces 42a and 43a function in the same manner as the cold air discharge ducts 53 and 54 are extended by the δ5 and δ6 dimensions shown in FIG. 3, so the cold air discharge ducts by the δ5 and δ6 dimensions. Can be shortened. Therefore, since the ventilation resistance can be reduced by that amount, the flow of the cool air becomes smooth, the increase in the input of the blower that circulates the cool air is reduced, and a refrigerator capable of saving energy can be provided. In addition, since the cold air discharge duct can be shortened, the material cost constituting the duct can be reduced accordingly, and thus a refrigerator advantageous in terms of manufacturing cost can be provided.

  Next, the freezer compartment 34 will be described more specifically with reference to FIG. 4 is a cross-sectional view taken along the line AA in FIG.

  The containers 42, 43, and 44 are arranged so that the side walls 42s, 43s, and 44s that constitute the food storage portion are positioned at intervals in the vertical direction without overlapping in the horizontal direction. Thereby, it is possible to provide a refrigerator that eliminates the overlapping of the side walls of the containers, saves material costs, and increases the storage capacity of the containers.

  The drawer frame 71 is provided on the drawer-type door 34 </ b> A provided on the front surface of the freezer compartment 34 so as to protrude rearward. The drawer frame 71 suspends the upper flange portion 44 g of the lower container 44, so that the lower container 44 is supported by the drawer frame 71. The movable roller 72 provided in the drawer frame 71 is configured to be slidable back and forth with respect to the door refrigerator main body 30 by sliding back and forth within a rail 73 provided in the refrigerator main body 30.

  The middle container 43 is placed on the upper flange 44 g of the lower container 44 and is configured to be movable back and forth together with the lower container 44. In addition, after the lower container 44 and the middle container 43 are pulled out together, the lower container 44 is left in the pulled out state, and only the middle container 43 is provided with the upper flange 44g of the lower container and the rail 74 provided on the refrigerator main body 30. It is configured to be able to slide backward using it.

  That is, the middle container 43 located above the lower container 44 can be slid back and forth with respect to the lower container 44 so that the stored food in the lower container 44 can be taken out easily. Therefore, the middle container 43 may be laterally displaced with respect to the lower container 44 during the slide. Therefore, the lateral displacement prevention piece 44h is raised from the upper flange 44g of the lower container 44 to prevent lateral displacement between the containers so that the overlapping portion between the lower container 44 and the middle container 43 does not laterally deviate. By reducing the rising dimension H3 of the lateral displacement prevention piece 44h to, for example, around 15 mm, it is possible to prevent lateral displacement while saving material costs.

  The upper container 42 slides the upper flange 42g portion back and forth in the rail 75 provided in the refrigerator main body 30 so that it can be moved back and forth with respect to the refrigerator main body 30 regardless of the positions of the other containers 43 and 44. It is configured to be slidable.

  In the present embodiment, as described above, since the overlapped portion of the middle container 43 and the lower container 44 is about 15 mm of the lateral displacement prevention piece 44h, the double wall between the side wall 13c and the side wall 14c of FIG. Therefore, it is possible to provide a refrigerator that can save container material costs. Moreover, since there is little double of the side wall of containers, the refrigerator with little reduction of the width dimension W3 of the middle container 43 can be provided. In addition, since the overall height of the lower container 44 can be made smaller than before, it is possible to provide a refrigerator that can reduce the molding cost as well as the material cost of the lower container itself.

  Further, since the size of the side wall of the middle container 43 is not covered by the lower container 44 and is almost entirely exposed, the middle container 43 can be easily seen and the depth of the container can be estimated from the appearance. can do.

  The configuration and effects of the present embodiment described above are summarized as follows.

  In a refrigerator provided with three-tiered containers in a freezer compartment, the back wall of the upper and middle containers is formed as an inclined surface, and a discharge port of a cold air discharge duct provided in a partition member that partitions the freezer compartment and the cooler compartment Since the cooling air is provided facing the inclined surface and the discharge cold air is guided into the lower container using the inclined surface, the inclined surface provided on the back wall of the container guides the discharge cold air and extends the size of the cold air discharge duct. Since it works in the same way as the time, the cool air discharge duct can be shortened accordingly. Therefore, since the ventilation resistance can be reduced, the flow of the cool air becomes smooth, and the increase in the fan input for circulating and blowing the cool air is small, so that a refrigerator that is advantageous in terms of energy saving can be provided. In addition, since the cold air discharge duct can be shortened, the material cost constituting the duct can be reduced accordingly, and thus a refrigerator advantageous in terms of manufacturing cost can be provided.

  In addition, when the container is pulled out with the pull-out door, the stored food stored on the inclined surface provided on the back wall of the container can easily move to the front of the container by dropping on the inclined surface due to gravity acting on the food itself. It is possible to provide a refrigerator that makes it easy to take out stored foods in the back of the container.

  Moreover, since the position of the discharge port of the cold air discharge duct is located in front of the rear wall of the flange portion formed behind the rear wall of the upper, middle, and lower containers, the discharged cold air is outside the rear of the container. Therefore, it is possible to provide a refrigerator with few cold short suck kits.

  In addition, the lower container is a rectangular container, and the rear wall of the flange portion formed behind the rear wall of the container is located on the cooler chamber side from the discharge port of the cold air discharge duct. Since the distance is reduced, the protruding dimension from the partition member of the cold air discharge duct can be reduced. Therefore, the ventilation resistance of the cold air discharge duct can be reduced, and an energy-saving refrigerator can be provided. In addition, since the deep lower container is rectangular and does not have a convex portion into the cabinet as in the conventional example, a refrigerator that is easy to use and has a high internal volume efficiency can be provided.

  In addition, the lower container back wall of the three-tiered container whose container depth is shallower toward the top is positioned on the back side of the box from the rising wall that forms the machine room, so the lower container back wall and the back of the box Since the distance to the cooler chamber on the side is reduced, the length of the cool air discharge duct can be reduced. Accordingly, the resistance of the air passage can be reduced, the flow of the cool air becomes smooth, and the increase in the input of the blower that circulates the cool air is small, so that a refrigerator that is advantageous in terms of energy saving can be provided.

  In addition, a return cold air passage for the entire freezer compartment is provided between the bottom surface of the lower container provided substantially horizontally and the bottom of the freezer compartment, and the height of the return cold air passage is substantially the same as the lower surface of the cooler. Since the gravity acting on the cold air can be reduced, there is little increase in the blower input etc. for circulating the cold air, so that it is possible to provide a refrigerator that is advantageous for energy saving.

  Further, since there is no long suction duct with a height difference as in the conventional example, it is possible to provide a refrigerator with low air path resistance when returning from the return cold air passage to the cooler chamber.

  In addition, the lower container of the three-stage container is suspended on a drawer frame provided on the door side, the middle container can be slid backward using the upper flange of the lower container, and the upper container is a rail provided on the side wall of the inner box Since the upper part can be slid and the overlapping part of the middle container and the lower container is about 15 mm of the lateral slip prevention piece, a refrigerator that can save the container material cost can be provided. Further, since the side walls of the containers do not overlap, it is possible to provide a refrigerator with little reduction in the width of the middle container. Further, since the overall height of the lower container can be made smaller than before, it is possible to provide a refrigerator capable of reducing the molding cost as well as reducing the material cost of the lower container itself.
