Abstract
A controlling method for a dryer is applied to a dryer, in which at least one of a heat pump system and a heater is selected as a heat source for heating air supplied in to a drum and a heat supply capacity of the heat pump system is more than that of the heater. The controlling method includes, when both the heat pump system and the heater are selected as the heat sources, turning the heat pump system on, turning the heater on after the heat pump system is normally turned on, turning the heater off to cool the drum and terminate drying after the drying is performed, and turning the heat pump system off after the heater is turned off.
Claims14
A dryer capable of drying clothes, the dryer comprising:
- a main body;
- a drum rotatably installed inside the main body for accommodating clothes therein;
- a driving motor for driving the drum;
- a heating unit including a heat pump system constructing a thermodynamic cycle, for heating air supplied into the drum, by including an evaporator at an exhaust side from the drum, a condenser at an inlet side of the drum, an expansion valve and a compressor and a heater installed at downstream of the condenser for heating air supplied into the drum, wherein a heat supply capacity of the heat pump system is more than that of the heater;
- a control panel having a variety of manipulation buttons for operating the dryer;
- and
- a controller configured to turn on or off at least one of the heat pump system or the heater according to a user selection inputted through the control panel and the controller is further configured to turn the heater on at an initial time before the heat pump system is normally operated and also after the heat pump system is normally operated.
A controlling method for a dryer capable of drying clothes, wherein the dryer includes a heat pump system and a heater for heating air supplied into a drum, the method comprising:
- receiving a user selection signal through a control panel included in the dryer, and
- turning on or off at least one of the heat pump system or the heater based on the user selection signal, wherein a heat supply capacity of the heat pump system is more than that of the heater wherein the turning on or off at least one of the heat pump system or the heater according to a user selection comprises;
- activating one of a normal drying mode and a high-speed drying mode based on the user selection signal;
- and
- turning on the heat pump system in the normal mode and turning on both the heat pump system and the heater in the high-speed drying mode.
