When an inkjet printer includes suction means for sucking the outside air into the inkjet printer, a heated recording medium is rapidly cooled by the air flowing in a vicinity of a discharge port for the recording medium. This causes fluctuations in surface temperature, resulting in degraded image quality. Accordingly, the inkjet printer has both a configuration capable of directly sucking, into a carriage, the outside air sucked into an apparatus, and a configuration of preventing the air from passing through an inside of the carriage. Thus, a temperature of the inside of the carriage can be reduced effectively. In order to prevent a reduction in temperature of the recording medium in the vicinity of the discharge port, a heater is arranged so as to increase a heating capacity of heating. Through temperature control on the heater based on a temperature of a region that is easily reduced in temperature, a local reduction in temperature of the recording medium is suppressed.

An inkjet printer records an image on a recording medium by ejecting ink onto the recording medium from a recording head mounted on a carriage. A housing suction fan is arranged on a rear surface of the housing for sucking a gas from an outside into an inside of the housing. A carriage suction fan is arranged on the rear surface of the housing opposite to the housing suction fan for sucking into the carriage the gas sucked by the housing suction fan. A rear surface exhaust fan and a side surface exhaust fan are arranged on the rear surface and a side surface, respectively, of the housing for exhausting the gas inside the housing to the outside. The gas sucked by the housing suction fan is sucked into the carriage by the carriage suction fan and flows into the housing without being sucked by the carriage suction fan.

A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.

In a case where suction means for taking in outside air into an inkjet printer is provided, a heated recording medium is abruptly cooled by a flow of air, thereby causing cooling unevenness, which is a factor of degradation of image quality. Further, it is difficult to efficiently cool an inside of a carriage. In view of the above, provided are a structure for allowing the outside air, which is taken into a device of the inkjet printer, to be directly sucked into the carriage, and a structure for preventing the outside air from passing through the carriage. Thus, the temperature inside the carriage can be effectively decreased. Further, mechanisms for exhausting the gas are provided on both sides of a housing, specifically, one mechanism is provided on a side surface of the housing and another mechanism is provided on a rear surface thereof.
