PROBLEM TO BE SOLVED: To provide a portable type cooling box capable of improving a cooling efficiency without changing a basic configuration having a cold insulation chamber formed with a suction port and a door member for opening or closing a front surface of this cold insulation chamber and without any situation that the suction port is closed by items stored in the cold insulation chamber and cooled.SOLUTION: This invention comprises a movable cooling box main body S provided with an opening part at its front surface and fixed with movable casters at its bottom part; a heat insulation chamber 2 of heat insulated structure provided with a door member T for opening or closing the front surface opening part to store items to be cooled; cooling means 8 for cooling the items to be cooled and stored in the heat insulation chamber 2; a suction port 15 formed at a clearance between a front end of a bottom plate 13 of the heat insulation chamber 2 and the door member T; a cold air circulation passage 10 for sucking air through the suction port 15, guiding it to the cooling means 8, heat exchanging it there and then circulating it within the heat insulation chamber 2 and guiding it to the suction port 15; and a suction guard member G arranged at the door member T, protruded toward an upper location of the suction port 15 under a state in which the door T closes the front opening part of the heat insulation chamber 2 to restrict storing of the items to be cooled and at the same time assuring air suction through the suction port 15.SELECTED DRAWING: Figure 2 |
