Abstract

<P>PROBLEM TO BE SOLVED: To secure a heat exchanging air passage on the inner side of a storage chamber with simple structure. <P>SOLUTION: Shelf pillars 40A, 40B are erected in a storage chamber 16, and a lateral pair of rails 32 are laid between the front and inner shelf pillars 40A, 40B and supported in the face-to-face attitude at the same height. The shelf pillar 40B on the inner side is formed in stepped shape of two stages, and the front facing face of the stepped part on the inner side is made a stopper face 48. When a tray 30 with food placed thereon is put into the storage chamber 16 while being received by the rails 32, push-in is regulated when the inner edge abuts on the stopper faces 48 of the shelf pillars 40. The deformation of the tray 30 caused by abutting on the inner wall 16A is thereby prevented while forming a clearance between the inner wall 16A and tray to secure a cold air passage where cold air flows in vertical and lateral directions over the whole surface. <P>COPYRIGHT: (C)2003,JPO

2. Description of the Related Art As an example of this type of storage, the quick freezer shown in FIGS. 8 and 9 is known. In this case, a storage chamber 2 and a cooler chamber 3 are provided side by side in a freezer body 1 made of a heat insulating box. Inside the cooler chamber 3, a cooler 5 which is circulated and connected to the refrigerating device 4 by a refrigerant pipe is housed at a central height position, and internal fan 6 is housed on both upper and lower sides thereof. On the side wall, rails 7 forming a pair on the left and right are provided in multiple stages via shelf posts 8. Then, the tray T on which the food ingredients S and the like are placed is placed on the rail 7
When the refrigerating device 4 and the in-compartment fan 6 are driven, the in-compartment air is sucked toward the cooler 5, and the cool air generated by heat exchange while passing through the cooler 5 causes the upper and lower in-compartments to be cooled. The fan 6 creates a circulating flow such as being blown out into the storage room 2, so that the foodstuffs S and the like are rapidly frozen.

Here, if the tray T has a structure in which the tray T is directly applied to the back wall 2A of the storage chamber 2, the cold air passage will be blocked at the back side of the storage chamber 2, and the tray T should be pushed in with a strong force. If it abuts, the back wall 2A may be deformed. Therefore, conventionally, for example, a channel material 9 is attached over substantially the entire height in the central portion of the back wall 2A of the storage chamber 2 in the width direction, and the tray T is abutted against the channel material 9 to cool the back wall 2A. The passage is secured and the back wall 2A is prevented from being damaged.

This is because relatively warm air tends to accumulate in the upper part of the refrigerator and relatively cool air tends to accumulate in the lower part of the refrigerator. Especially, in the quick freezer having the above structure, the cooler 20 is used. Cooler chamber 1 in which the upper and lower internal fan 21 are housed
Since 7 is formed in the shape of a duct that connects the upper part and the lower part of the inside of the refrigerator, the cold air near the inside fan 21 at the upper part of the inside of the refrigerator passes through the duct-shaped cooler chamber 17 to the lower portion of the inside of the refrigerator, and vice versa. It is considered that warm air near the lower internal fan 21 easily flows through the duct-shaped cooler chamber 17 to the upper part of the internal compartment, and the above-mentioned temperature variation becomes remarkable. Due to such a variation in the internal temperature, the food or the like placed particularly in the upper part of the internal compartment is exposed to a large temperature change, and there is a possibility that the quality is deteriorated due to evaporation and sublimation of water.

As a countermeasure against this, when the refrigerating device 24 is stopped to stop the circulating supply of the cool air, either one of the upper and lower internal fan 21 is not stopped and is continuously operated. . For example, when the upper internal fan 21 is continuously operated, as shown by the arrow in FIG. 6, the internal fan 21 passes through the suction port 28 on the front surface of the cooler 20 and the air outlet 29 on the front surface of the lower internal fan 21. A circulating flow is generated in which the inside air is sucked into the cooler chamber 17 and is blown into the inside from the air outlet 29 on the front surface of the upper inside fan 21, that is, the inside of the inside is agitated vertically. Then, Fig. 7 (B)
As shown in, even when the refrigeration system 24 is stopped, the variation in the internal temperature can be suppressed to a small level. Therefore, deterioration of the quality of the stored food is prevented.

Contrary to the above, when the lower internal fan 21 is continuously operated, the internal air flows through the suction port 28 on the front surface of the cooler 20 and the air outlet 29 on the front surface of the upper internal fan 21. A circulating flow is generated such that the air is sucked into the cooler chamber 17 and blown into the inside from the air outlet 29 on the front surface of the lower inside fan 21. In the same manner, it is possible to suppress variations in the inside temperature. Further, each time the refrigeration system 24 is turned off, the upper internal fan 21 and the lower internal fan 21 may be alternately operated continuously.
