Abstract
A linear compressor according to the present disclosure may include a cylinder provided with at least one groove, a piston reciprocating within the cylinder, a motor configured to provide a driving force to move the piston within the cylinder, an inverter configured to perform a switching operation to transmit electric power to the motor, and a controller configured to receive temperature information from the electronic device and control the inverter to preheat the motor based on the received temperature information.
Claims14
A linear compressor provided to an electronic device, the linear compressor comprising:
- a cylinder that defines at least one groove;
- a piston configured to reciprocate within the cylinder;
- a motor configured to generate a driving force and to drive the piston to reciprocate within the cylinder;
- an inverter configured to perform a switching operation and to transmit electric power to the motor;
- and
- a controller configured to receive temperature information related to a temperature of the linear compressor from the electronic device and to control the inverter to preheat the motor based on the temperature information, wherein the controller is configured to, based on activation of the electronic device, control a preheating operation of the motor to increase the temperature of the linear compressor in a state in which the piston is stopped,
- wherein the controller is further configured to, in response to a control command for starting operation of the linear compressor, determine whether or not to preheat the motor based on the temperature information that is received within a predetermined period of time elapsed from a time instant corresponding to generation of the control command.
