BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, cool air is sent from a cooler to one of the at least two adjacent insulated rooms for keeping the object to be insulated, and the one insulated room is cooled to a required temperature. The one cold storage room and the other cold storage room are partitioned by a first partition wall and a second partition wall arranged so as to sandwich the spacer, and the cold heat of one of the cold storage rooms is a material having a required thermal conductivity. Is transmitted to the other cold storage room by the floor formed in step (1).
[0019]
A gap region formed by interposing a spacer between the first partition wall and the second partition wall is communicated with the other cold storage room by a communication portion, and a blower is provided on the second partition wall. . Then, when the gas in the gap region is supplied to the other cool room by the drive of the blower and becomes negative pressure state, the gas in the other cool room is sucked into the gap region. A circulation path is formed between the cold storage room. While the gas circulates along this circulation path, the gas is cooled by contact with the floor of another cool room, and the entire other cool room is kept cool to a required temperature higher than the temperature of one cool room. .
[0020]
As described above, the cold air in one cold storage room is not directly supplied to the other cold storage room, but the cold heat conducted to the floor of the other cold storage room is diffused by the circulation of the gas, so that the other cold storage room is required. Keep cool to the temperature. Therefore, it is possible to prevent cold heat from concentrating on a part of the other cold storage room, and to prevent freezing from occurring on the cold storage object regardless of the arrangement position of the cold storage object in the rear room.
[0021]
The above-mentioned communication part is formed by providing a plurality of grooves in a direction intersecting with the second partition wall on the floor of the other cool room, and extending any or all of the grooves to the gap region. Therefore, as described above, the circulating gas is sucked into the gap region through the groove, and accordingly, the floor of the other cold storage room is deprived of heat, and the gas passing through the groove is cooled. As described above, the heat exchange is performed by passing through the inside of the groove provided on the floor of the other cold storage room, so that the efficiency is high.
[0022]
Further, in the present invention, any or all of the above-described grooves extend to one of the cold storage chambers, and a closing member that closes each of the extended grooves is detachably fitted to each of the grooves. A first partition wall stands on the closing member. Therefore, in the summer or the like, when keeping the other cold storage room at a relatively low temperature, by removing the closing member, the cool air of one of the cold storage rooms is taken into the circulation path described above, and is circulated to the other cold storage room. Can be adjusted to lower the temperature of the gas. Thus, even when the temperature difference between the other cool room and the outside air is large, it is possible to prevent the freezing object in the other cool room from freezing.
[0023]
Further, in the present invention, by opening the lid provided on the window of the first partition wall, the cool air in one of the cold storage rooms can be further taken into the circulation path described above. Therefore, even if the temperature difference between the other cool room and the outside air is further large, it is possible to prevent the freezing object in the other cool room from freezing.
[0024]
On the other hand, in the present invention, of the flow path from the communicating portion of the gap region to the blower, an appropriate part having a relatively short flow path distance, for example, a flow path changing member in a part immediately below the blower, For example, it is arranged horizontally so that the flow path distance becomes longer. That is, it is possible to prevent the flow rate of the portion from being higher than the flow rates of the other portions. In addition, of the flow paths, an appropriate part having a relatively long flow path distance, for example, a flow path changing member in a part far from the blower, so that the flow path distance of the part becomes shorter, for example, to the blower Arrange diagonally. That is, the flow rate of the portion is secured to a required flow rate. Thereby, the flow rate is made uniform over substantially the entire flow path, and the temperature distribution of the other cool storage chambers can be made more uniform.
[0025]
Further, in the present invention, since a plurality of through holes are formed in a portion of the predetermined spacer on the flow path, the flow rate described above can be made more uniform.
[0026]
By the way, in the present invention, the first partition wall, the second partition wall, and the spacer are movable, so that the capacities of one of the cold storage chambers and the other of the cold storage chambers can be appropriately changed.

【The invention's effect】
According to the first aspect of the present invention, the partitioning section that partitions one cold storage chamber and the other cold storage chamber has the first partition wall facing the one cold storage chamber and the second partition wall facing the other cold storage chamber. A gap region is formed by interposing a spacer between the partition wall and the partition wall, and the blower is provided on the second partition wall, and a communication portion that communicates the gap region with the other cool room is provided. Therefore, without supplying the cold air from one cool room directly to the other cool room, the heat conducted to the floor of the other cool room is diffused by the circulation of gas, so that the other cool room has the required temperature. Can be kept cool. Therefore, it is possible to prevent cold heat from concentrating on a part of another cold storage room, and to prevent freezing from occurring on the cold storage object regardless of the arrangement position of the cold storage object in the rear room.
[0060]
According to the second aspect of the present invention, the communication portion is provided with a plurality of grooves in a direction intersecting with the second partition wall on the floor of the other cold storage room, and extends any or all of the grooves to the gap region. The heat exchange efficiency is high because it is formed by providing the heat exchanger.
[0061]
According to the third aspect of the present invention, any or all of the grooves extend to one of the cold storage chambers, and a closing member that closes each of the extended grooves is detachably fitted into each of the grooves. Since the first partition wall is erected on the closing member, when the other cold storage room is to be kept at a relatively low temperature in summer or the like, by removing the closing member, The cool air in the cool room is taken into the circulation path described above, and the temperature of the gas circulated to the other cool room can be adjusted so as to be lower, whereby the temperature difference between the other cool room and the outside air is large. Even if there is, it is possible to prevent freezing from occurring in the insulated objects in other insulated rooms.
[0062]
According to the fourth aspect of the present invention, by opening the lid provided on the window of the first partition wall, the cool air in one of the cold storage chambers can be further taken into the above-mentioned circulation path, so that the other cold storage chambers can be taken. Even when the temperature difference between the room and the outside air is even larger, it is possible to prevent freezing from occurring in the object to be kept cold in other cool rooms.
[0063]
According to the fifth aspect of the present invention, of the flow path from the communicating portion of the gap region to the blower, the flow path changing member is provided at an appropriate portion having a relatively short flow path distance, and the flow path distance of the portion is relatively small. It is disposed so as to be longer, and among the flow paths, a flow path changing member is disposed at an appropriate portion having a relatively long flow path distance, and the flow path changing member is disposed such that the flow path distance of the portion is shorter. Therefore, the flow rate is made uniform over substantially the entire flow path, and the temperature distribution of the other cold storage chambers can be made more uniform.
[0064]
According to the sixth aspect of the present invention, since a plurality of through holes are formed in a portion of the predetermined spacer on the flow path, the above-described flow rate can be made more uniform.
[0065]
