COOLED STORAGE APPARATUS

PURPOSE:To free a cooled storage apparatus from the condensation of moisture in the vicinity of an intake passageway for outer air so as to prevent rotting or changes in quality, of stored matter which are due to drippings of condensed water by forming as the intake passageway for outer air a passageway by which a storage chamber communicates with the space outside the cooled storage apparatus and by providing a heater for heating the intake passageway for outer air. CONSTITUTION:Inside the insulating casing of a cooled storage apparatus 1 a storage chamber 8 and a chilled air passageway 7 are formed and the storage chamber 8 is cooled by the use of an evaporator provided in the chilled air passageway 7. An intake passageway for outer air 33 is formed as a means by which the storage chamber 8 communicates with the outer space and equipped with an electric heater 44 for its heating. In this constitution, the inside of the storage chamber 8 is cooled, on the one hand, under the cooling by the evaporator and the air therein is humidified, on the other hand, by the intake of humid outer air through the intake passageway for outer air 33 on the other hand. This intake passageway for outer air 33 is heated by the electric heater 44 so that the outer air passed therethrough to the storage chamber 8 is also heated and hence the condensation of moisture can be prevented.
