CONDUIT WITH IMPROVED ELECTRIC HEATING ELEMENT AND CLOTHES DRYING MACHINE PROVIDED WITH SUCH A CONDUIT

摘要

Conduit (1) is for transmitting and heating air-flow, it inside it include the layer that at least one is formed by thick film heating element (2), wherein the heating element (2) is used as positive temperature coefficient (PTC) peripheral members and is disposed relative to the cross section of airflow line, the mode being namely oriented substantially parallel flows to the gas, and making the latter not is even part by such thick film layers. In a kind of preferred embodiment, the heating element (2) is subdivided into multiple individually heating element (R1 R2 with different arrangements, and motivate R3) continuously so that the power input started is to maintain within preset limit with the mode of accumulation, and the power input in stable state is reduced to a rather low value, the value is still sufficiently high to ensure that an acceptable power output is horizontal.
