Description

Technical Field

[0001] The present invention relates to the technical field of clothes dryers, and in particular to a clothes dryer base and a clothes dryer. Background Art

[0002] A clothes dryer is a household appliance that evaporates the moisture in clothes instantly by blowing hot air. The appearance and structure of a drum dryer are similar to those of a drum washing machine. It also uses the mechanical force of an electric motor to rotate the drum. The clothes are constantly lifted up and dropped down in the drum, and then lifted up and dropped again. The clothes are shaken up by repeated movements. The dry hot air blown out by the electric heater or the compressor heat pump heater passes through the clothes and is discharged outdoors or circulated inside the air duct, continuously removing moisture from the clothes, thereby achieving the purpose of drying the clothes. A condensing device can also be added to the machine to condense the moisture into water and then discharge it into the sewer through the drain pipe.

[0003] However, in the prior art, when the condensed water of the clothes dryer flows out, the flow direction of the condensed water is unstable and a large amount of internal heat is taken away, thereby increasing the energy consumption of the clothes dryer and causing the working efficiency of the clothes dryer to be low.
