Patent ID: 8793894

Claim:
A clothes drying appliance, comprising: a base which comprises a division plate to divide said base into a first side and an opposed second side; a heat source provided at said first side of said base and a hot wind channel at said second side of said base, wherein said heat source has an air inlet and comprises a wind turbine and a PTC heating element having a PTC outlet for heating up a flow of air from said air inlet and for generating a flow of hot air at said PTC outlet toward said hot wind channel, wherein said hot wind channel has a water outlet at a bottom of said hot wind channel and an arch-shaped wall at an end of said hot wind channel, wherein said water outlet is formed at said bottom of said hot wind channel between said heat source and said arch-shaped wall, wherein said arch-shaped wall is extended from said bottom of said hot wind channel, such that said hot air is guided to flow along said bottom of said hot wind channel toward said arch-shaped wall, wherein said bottom of said hot wind channel is positioned below said PTC heating element, such that said water outlet is positioned below said PTC heating element; a frame provided on said base, wherein said frame comprises a warm air division plate, a protection plate, and a top net plate, wherein said protection plate is positioned on said base to define said hot wind channel below said protection plate, wherein a warm air cushioning chamber is formed between said protection plate and said warm air division plate, wherein a clothes drying chamber is formed between said division plate and said top net plate, wherein said arch-shaped wall guides said hot air from said hot air channel along said bottom side thereof until said hot air hits said arch-shaped wall to said warm air cushioning chamber through said protection plate in order to initially mix with cool air within said warm air cushioning chamber for initially reducing a temperature of said hot air within said warm air cushioning chamber, wherein the temperature within said warm air cushioning chamber is then gradually increased; a cover covering said frame to conceal said warm air cushioning chamber and said clothes drying chamber, wherein at least an exhaust hole is provided on a top side of said cover for discharging wet air from said clothes drying chamber; and a control unit which comprises a humidity sensor provided at said warm air division plate within said clothes drying chamber and a temperature sensor supported within said warm air cushioning chamber, wherein said humidity sensor detects humidity in said clothes drying chamber that when said humidity is below a preset humidity value, said PTC heating element is deactivated to generate heat, wherein said temperature sensor detects temperature within said warm air cushioning chamber that when said temperature is higher than a preset temperature value, said PTC heating element is deactivated to generate heat.
