Abstract
Disclosed are a dishwasher and a method for controlling the same, in which in a situation where an operating rotational speed or an operating frequency of a washing pump is reduced in response to a state of progress of a cycle of the dishwasher, an operating rotational speed or an operating frequency of each of a compressor and a blower module which may act as a main noise generating source may be reduced, thereby maintaining a total low noise generation amount and remarkably saving electric power consumption.
Claims20
A dishwasher comprising:
- a tub having a washing space defined therein and accommodating dishes therein;
- a sump storing therein washing water to be supplied to the tub;
- a washing pump configured to pressurize washing water to be supplied to the tub;
- a heat pump module including:
- a compressor configured to compress refrigerant;
- a condenser configured to receive the refrigerant having flowed through the compressor;
- an evaporator configured to receive the refrigerant having flowed through the condenser;
- and a blower module configured to generate airflow to be heat-exchanged with the refrigerant in the evaporator;
- and a controller configured to determine a pump rotational speed of the washing pump based on a selected washing course, wherein the controller is configured to:
- adjust an operating condition of the heat pump module based on a pump rotational speed condition of the washing pump set in a corresponding manner to the selected washing course;
- and control the heat pump module to operate according to the adjusted operating condition.
A method for controlling a dishwasher, wherein the dishwasher includes:
