Abstract: PURPOSE:To reduce frosting of a cold storage agent and to enable continuous use by having a cold storage unit arranged to be thermally exchanged with a second cooler and a freezer unit outside the cold, storage chamber composing first and second coolers connected to the unit to form a refrigerating cycle, a freezing temperature controller for controlling operation and stop of an interior blower, and changeover switch. CONSTITUTION:When an indoor blower 26 is operated by battery 27 as a power source and a thermal insulation chamber 33 is cooled to an arbitrary temperature, a thermal insulation temperature control thermostat 42 is opened to stop the blower 26. Then, the blower 26 is operated and stopped by the thermostat 42 to control a thermal insulation chamber 22 to an arbitrary temperature. A compressor 36, a condenser fan motor 35 are continuously operated until a cold storage agent 32 is completely frozen and a cold storage temperature control thermostat 40 is opened. Even if the agent 32 is frozen while the blower 26 is being operated, after the temperature of chilled gas circulated by a cooler 28 is cooled to be dehumidified to a temperature lower than the melting point of the agent 32, the gas is circulated to a cold storage unit 34 arranged to be thermally exchanged with a second cooler 30. Thus, frosting on the surface of the agent 32 can be prevented, and freezing of the agent 32 can be accelerated.

Abstract: PURPOSE:To eliminate a bridge without entailing any damage to a solid material by opening both first and second storage tanks for interconnection through each bottom part, setting up a movable plate in this interconnected opening, and making the solid bridge at this interconnected opening so as to be razed by motion of the movable plate. CONSTITUTION:A storage tank 1 is interconnected to a sub-storage tank 32 by a bottom opening 31, and a movable plate 8 is installed in an opposed part of the opening 31 of this sub-storage tank 32. Then, this movable plate 8 is constituted so as to make it move up and down by a drive motor of a stepped belt 13 via a wire 22. With this constitution, a solid material on the bottom of the sub-storage tank 32 is slightly pressed to the side of the opening 31 by vertical motion of the movable plate 8, and thereby a solid bridge 30 at the opening 31 is razed. This vibration is limited to the inside of the sub-storage tank 32, so that no influence is given to the solid material in the storage tank 1. Consequently, the sold material is conveyable upon eliminating the bridge without breaking any corner of the solid material.

Abstract: PURPOSE:To prevent degradation of quality of substances to be transported, by separating a cold accumulating room and an insulating room thermally and completely so that a cold accumulating agent can accumulate cold and the temperature within the insulating room can be maintained at a set value within a refrigerating temperature zone by controlling cool air volume to be sent into the insulating room. CONSTITUTION:An insulating partition wall 21 of heat insulating characteristic separates a cold accumulating room 15 and an insulating room 22 thermally. A discharge port 23 is arranged at one end of the wall 21 on the side of an insulating fan 16, and an insulating duct 25 is mounted on the wall 21 for introducing air in the insulating room 22 from the opposite end of the wall 21 into an inlet port 24. A freezer unit 26 and a battery 27 which works as a power source for the insulating fan 16 are mounted outside of an insulating container body 10. Accordingly, the temperature in the insulating room 22 never drops down under 0 deg.C due to heat transmission from the cold accumulating room 15. Thus a cold accumulating insulating container in which substances to be kept cool never freeze can be obtained.
