The 7 heat-insulating walls (27) are in contact with the surface and covered with a slight gap, and a side plate (26b) is installed between the cold lice stinger exit (19b) to form a return path. In addition, instead of the aforementioned clearance (21) of the upper case (12) and the lower case (11), as shown in FIG. 4 with the same symbol as the figure, the upper case (12) is loaded on the lower phase (11) And, the sealing piece (23) from the partition wall (6) is abutted on the upper end of the upper box (12), to block the blowing of the cold air toward the sealing gasket part in front of the box, and install the cold air on the front bottom surface of the upper meal (12) The circulation port (22,) may also have the same structure as described above, so as to achieve effective air-conditioning circulation. Moreover, the aforementioned outflow port (25) is not a necessary structure. As shown in FIG. 4, circulating cold air may flow out from the gap between the middle, lower and upper boxes (11) and the upper box (12) at the rear, and it may be placed in front of the cover (20). A wind guide (20a) is provided below, and the air-conditioning distribution to the upper and lower boxes (12) can be taken as appropriate. With the structure as described above, as before, the cold air blown from the blow-out port (59) is due to the surroundings of the storage tanks (52), (51), that is, the bottom of the door inner panel (49a) or the outside is equipped with a condenser. The wall (58), the lower peripheral wall (57) which is affected by the heat of the compressor (61) arranged in the machine room (60), and the inner peripheral wall of the freezer (47) which is affected by the high temperature atmosphere and the temperature rises The temperature of the cold air itself rises. As a result, the disadvantages of reducing the cooling force for containing food are eliminated, and the pressure loss caused by the circulation around the box is reduced. 5 The cold air can flow easily. And 'the cold air blown out from the cold air outlets (19a), (19b) is circulated from the upper box (12) to the lower box ⑴)' Since the cold air which can maintain a low temperature with a large amount of flow can directly cool and contain the food, the food is cooled Stronger force, can effectively freeze 91565 -12- 1238239. Since the outflow port (25) is installed under the lower box (12), it is a circulation of cold air that can flow into the box (12) from the upper part. Those with good performance. In addition, the return duct (26) formed with the lower case (12) is easy to form, which can reduce the manufacturing cost, and the installation of the back components such as the ejection duct (18) is also easier. The outflow port (25) is provided with a rib (32) protruding from the inside of the storage box (12). In case the storage port blocks the outflow port (25), the air conditioner can still be ensured by the protruding rib (32) . And even if the outflow port (25) is not put through the back of the box, the circulated cooling air still flows out from the gap between the upper middle box and the lower box (11) and the upper box (12), and from this gap to the cooler (13). ) Can also extend the return duct (26) of the suction port, and it is not necessary to install a side plate (26b) that restricts the width of the return duct (26). In addition, the upper end of the front wall of the upper box (12) or lower box (11) of the aforementioned door inner panel (9a) is shown in FIG. 5, and a circle is installed from both ends of the upper part of the box body (1 丨丨 or ^)). The arc-shaped protruding piece (28) may have a structure in which the front end abuts on the surface of the door inner panel (9a). If so, the heat conduction with the door inner panel (9a) can be minimized by the arc-shaped protruding piece (28). And the cover body is not a structure fixed to the top of the partition wall as in the above embodiment, as shown in FIG. 6, for example, a cover b (20 b) having a flange portion (20 b) on the periphery of the opening shape of the storage box (11). 20,), the air-conditioning outlet (19) is opened from the notch (20c) of the flange portion (20b) formed on the back side of the cover B (20,) and the notch with the inclined surface The guide (20d) can also be fastened, and the inclined surface is formed at the rear end of the cover B (20 ') by a roller (29) protruding from the top of the box body installed at the rear end of the storage box (u). 91565 -13- 1238239
