Clothes dryers and washing and drying machines

Abstract

A clothes dryer (50), comprising: a casing (1); a rotating drum (4), which is freely rotatably arranged in the casing (1); and an electric motor (7), which is used to rotate the rotating drum (4). ) for rotational drive. In addition, it is equipped with: a drying air generating unit, which is used to generate drying air, and has a dehumidification unit and a heating unit; air; and a circulation duct (12) for recirculating drying air discharged from the rotary drum (4) to the rotary drum (4) via a drying air generating unit. In addition, a housing for accommodating the dehumidification unit and a heating unit, a sprinkler unit for removing foreign matter adhering to the dehumidification unit, and a drainage path (32) for draining water in the housing are provided. A foreign matter trap (34) is further provided for trapping foreign matter removed from the dehumidification unit by the sprinkling unit, and the foreign matter trap (34) is disposed upstream of the air flow of the drying air in the dehumidification unit. side below.

Description

technical field [0001] The present invention relates to a clothes dryer and a washing and drying machine for drying clothes and the like. Background technique [0002] In conventional clothes dryers, there is a problem that lint such as lint generated from fiber products such as clothes is mixed with drying air, adheres to the air blower and heat exchanger installed in the circulation air duct, and accumulates, causing the air blower and heat exchange to become unstable. The reason for the degradation of the function of the device. Therefore, a lint filter for trapping lint from the drying air is installed in the circulation duct. [0003] However, since the drying air flowing in the circulation duct needs to ensure a constant air flow rate, the mesh of the lint filter needs to be formed with a certain degree of thickness. Therefore, it is difficult to completely remove the lint from the drying air that has passed through the lint filter, and a part of the lint that has pa...

[0002] In conventional clothes dryers, there is a problem that lint such as lint generated from fiber products such as clothes is mixed with drying air, adheres to the air blower and heat exchanger installed in the circulation air duct, and accumulates, causing the air blower and heat exchange to become unstable. The reason for the reduction of the function of the device

[0015] However, in the conventional structure, there is a problem that if the foreign matter flowing together with the washing water and the dehumidification water clogs the drainage path, the dehumidification water generated by the evaporator 159 during the dry operation cannot be discharged.

In addition, there is also the following problem: when a blocking portion 167 for blocking foreign matter is provided in the drainage channel of dehumidification water, foreign matter accumulates in the blocking portion 167 and dehumidification water cannot be discharged.
