  As a result, the cold air supplied to the ice storage box portion and the food storage box portion of the refrigeration case, after filling the ice storage box portion and the food storage box portion, flows out over the front wall having the lowest height. In addition, the entire area in each ice storage box portion and food storage box portion can be cooled substantially uniformly without overcoming the both side walls of each ice storage box portion and food storage box portion and flowing out of the short circuit. In addition, it is possible to prevent the cold air in the food storage box portion from passing over the partition wall higher than the front wall and flowing out to the ice storage box portion, so that the ice in the ice storage box portion is not smelled. In addition, even when outside air with a relatively high temperature enters the refrigeration case when the door is opened and the refrigeration case is pulled out, the outside air passes over the front wall and flows out to the cooler at the same time as described above. The cold air in the ice storage box that fills faster than the food storage box flows over the partition wall and flows into the food storage box, and is combined with the cold supplied directly from the cooler to the food storage box. The outside air in the section can be expelled and cooled quickly, and efficient cooling becomes possible.

Further, a recess 10 is formed in the back surface of the cooling chamber 8, and a control board 11 for controlling the cooling operation is disposed in the recess 10.

  Reference numeral 12 denotes an ice making device incorporated in the upper part of the freezer compartment 4, which supplies water from the water supply pipe 13 to the ice making tray 14 to make ice, and the ice making tray 14 is appropriately rotated by a signal from the control board 11. Then, the ice is accumulated in an ice storage box portion which will be described later.

  Reference numeral 15 denotes a detachable refrigeration case disposed in the freezer compartment 4. As shown in FIG. 6, an ice storage box portion 16 located below the ice making device 12 and a freezing case located beside the ice storage box portion 16. And a food storage box portion 17 for storing food and the like.

  In the freezing case 15, the ice storage box portion 16 and the food storage box portion 17 are integrally formed of resin through a partition wall 18. In this refrigeration case 15, the heights of the side walls 19, the partition wall 18, and the front wall 20 are set such that the height of the side walls 19> the partition wall 18> the front wall 20. Further, the refrigeration case 15 has a slanted shape 21 in which the front upper corner portion of the partition wall 18 becomes lower toward the front lower side, and the handle portion 22 is formed with a substantially central portion at the upper end of the front wall 20 being recessed backward. Further, the freezing case 15 connects the lower part of the gap 23 between the ice storage box part 16 side and the food storage box part 17 side of the partition wall 18 between the ice storage box part 16 and the food storage box part 17 with a rib 24. And the inclined surface part 25 is formed in the front side lower corner part of the said ice storage box part 16 and the food storage box part 17. As shown in FIG.

The freezer compartment 4 is formed with a cold air passage 26 between the front wall 20 of the freezer case 15 and the door 7 of the freezer compartment 4 as shown in FIG. 26 is formed so that the food storage box portion 17 side is larger than the ice storage box portion 16 side,
The amount of cold air flowing through the cold air passage 26 formed between the front wall 20 of the freezing case 15 and the door 7 of the freezer compartment 4 is distributed differently between the ice storage box portion 16 side and the food storage box portion 17 side. .

  In this embodiment, since the position of the handle portion 22 is moved toward the food storage box portion 17 side, the concave shape position that becomes a part of the cold air passage is also on the food storage box portion 17 side. Is increased on the food storage box 17 side.

  A storage container 27 is arranged at the lower part of the freezing case 15 and is supported together with the freezing case 15 on a rail (not shown) of the door 7 and is pulled out from the refrigerator main body 1 together with the freezing case 15 by the drawer of the door 7. It is like that.

  In addition, on the rear wall of the freezer compartment 4, an ice making cold air outlet 28 (see FIG. 3) for supplying cold air to the ice making device 12 and the ice storage box portion 16, and freezing cold air for supplying cold air to the food storage box portion 17. A blowout port 29 (see FIG. 4) and a storage container cool air blowout port (not shown) for supplying cool air to the storage container 27 are formed, and a cold air return port 30 (see FIGS. 3 and 4) is formed at the bottom. Is formed.

  Next, the operation of the above configuration will be described.

  First, cold air is generated in the cooling chamber 8, and this cold air is supplied to the refrigerator compartment 2, the vegetable compartment 3, and the freezer compartment 4 to cool these chambers.

  The cold air supplied to the freezer compartment 4 is supplied from an ice making cold air outlet 28, a freezing cold air outlet 29, and a storage container cold air outlet (not shown). The food storage box portion 17 and the storage container 27 are supplied to each other and return to the cooling chamber 8 from the cold air return port 30.

  Here, when the cold air supplied to the ice storage box portion 16 and the food storage box portion 17 of the freezing case 15 fills the ice storage box portion 16 and the food storage box portion 17 to the full extent, the front walls 20 thereof. Since the height is the lowest, it passes over the front wall 20, flows down the cold air passage 26 between the front wall 20 and the door 7 of the freezer compartment 4, flows into the storage container 27, and then cools from the cold air return port 30. It will return to the chamber 8.

  Therefore, the cold air does not flow over the both side walls 19 of the refrigeration case 15 and flows out to the cold air return port 30, and the entire area in each ice storage box portion 16 and food storage box portion 17 is cooled substantially uniformly. be able to. In addition, since the cold air in the food storage box portion 17 does not flow over the partition wall 18 higher than the front wall 20 and flows out to the ice storage box portion 16 side, the ice in the ice storage box portion 16 does not smell.

  Further, the cold air that has passed over the front wall 20 of the freezing case 15 flows smoothly from the front side portion of the storage container 27 below it to the cool air return port 30 at the rear, and the food in the storage container 27 is also efficiently cooled. be able to. Further, the cold air passage 26 formed between the front wall 20 of the freezing case 15 and the door 7 of the freezer compartment 4 and the cold air passage due to the concave shape of the handle portion 22 are closer to the food storage box portion 17 side than the ice storage box portion 16 side. Therefore, the amount of cold air that flows from the ice storage box portion 16 and the food storage box portion 17 over the front wall 20 to the cold air passage 26 becomes an amount corresponding to the capacity, and the efficiency is increased. Cooling is possible.

On the other hand, when food is put in and out of the freezer compartment 4 or ice is taken out, if the door 7 is opened and the freezing case 15 is pulled out, relatively high temperature outside air enters into the freezing case 15 and the refrigerator is left as it is. It will be stored in the main body 1.

  At this time, in the refrigeration case 15, among the relatively high temperature outside air that has entered the refrigeration case 15, first, the outside air in the ice storage box 16 is filled in a short time because its capacity is relatively small. The air is pushed up by the incoming cold air and flows out to the cooling chamber 8 over the front wall 20 as described above. Then, the cold air in the ice storage box portion 16 moves over the partition wall 18 in such a manner as to push out the outside air remaining in the upper portion of the food storage box portion 17 having a relatively large capacity and a slow filling of the cold air. It comes into the part 17. As a result, the inside of the food storage box portion 17 is combined with the cold air directly supplied from the cooling chamber 8 to the food storage box portion 17 so that the cold air is filled in a short time. Therefore, the food stored in the food storage box portion 17 can be quickly cooled. In particular, when food is stored in the food storage box 17, the quick cooling is effective because the food may be in contact with the outside air until it is taken away from the store where it is taken home.

  Further, since the freezing case 15 has an oblique shape 21 in which the front upper corner portion of the partition wall 18 becomes lower toward the lower front side, the strength of the front end portion of the partition wall is higher than that in the case where the front upper corner portion is left at a right angle. And the damage of the partition wall 18 can be prevented. Moreover, since the slanted shape 21 of the partition wall 18 is connected to the portion of the handle portion 22 of the refrigeration case 15 closer to the ice storage box portion 16, the resistance against twisting of the refrigeration case 15 as a whole can be improved. The overall strength can be improved.

  Furthermore, since the freezing case 15 is formed with a handle portion 22 with the substantially central portion of the upper end of the front wall 20 being recessed backwards, a clearance of manual insertion level can be ensured between the freezing case 15 and the inner surface of the door. it can. Therefore, it becomes easy to handle the freezing case 15 to the handle portion 22 and the usability is improved.

  In addition, the refrigeration case 15 has a structure in which a lower portion between the ice storage box portion 16 side and the food storage box portion 17 side of the partition wall 18 between the ice storage box portion 16 and the food storage box portion 17 is connected by a rib 24. Therefore, even if the refrigeration case 15 is formed by resin molding, the lower part of the partition wall 18 is connected by the rib 24, so that the strength is improved and the ice storage box 16 side and the food storage box part 17 side The gap 23 between the two becomes a heat insulating space, reducing the thermal influence between them and enabling good cooling.

  Furthermore, since the freezing case 15 is provided with an inclined surface portion 25 at the front lower corner portion of the ice storage box portion 16 and the food storage box portion 17, the front lower corner portion of the freezing case 15 is the inner surface of the door when the freezing case 15 is attached or detached. And the like can be easily removed and attached.

  As described above, this refrigerator provides an inexpensive and good cooling performance free from uneven cooling and odor problems without increasing the number of parts such as a lid, but within the scope of achieving the object of the present invention. It goes without saying that various changes can be made.

  As described above, the present invention can suppress the occurrence of uneven cooling and odor problems without providing a lid or the like, and can provide a refrigerator that is inexpensive and has good cooling performance. Widely applicable to refrigerators.
