A beverage maker includes a fermentation tank, a dispenser, a water supply heater configured to heat water supplied from a water supply pump or an external water supply source, a first channel valve that opens and closes a first channel that connects the water supply heater to the dispenser, a second channel valve that opens and closes a second channel that connects the water supply heater to the fermentation tank, and a controller that performs a first cleaning operation by guiding heated water to the dispenser through the first channel based on opening the first channel valve for a first cleaning time, and a second cleaning operation by guiding heated water to the fermentation tank through the second channel based on opening the second channel valve for a second cleaning time. The controller performs the first cleaning operation and the second cleaning operation based on an order.

A dehumidifier includes a body having an inlet for suctioning air and an outlet for discharging air; a compressor, disposed at the body, for compressing a refrigerant; a condenser for condensing the refrigerant compressed from the compressor; an expander for expanding the refrigerant condensed from the condenser; an evaporator, disposed at upstream of the condenser according to the flow direction of air, for evaporating the refrigerant expanded from the expander; a condensate water tank to store condensate water condensed from the evaporator; and a condensate water pipe, connected to the condensate water tank, for flowing the condensate water to be heat-exchanged with the refrigerant compressed from the compressor.

Dehumidifier

A heat pump includes a first cycle device and a second cycle device. The first cycle device is connected such that, in a heating operation, a first refrigerant is circulated in an order of a first compressor, a 4-way valve, a first heat exchanger, a second heat exchanger, a first expansion mechanism, a third heat exchanger, the 4-way valve, and the first compressor, and such that, in a cooling operation, the first refrigerant is circulated in an order of the first compressor, the 4-way valve, the third heat exchanger, the first expansion mechanism, the second heat exchanger, the first heat exchanger, the 4-way valve, and the first compressor. The second cycle device is connected such that a second refrigerant is circulated in an order of a second compressor, a fourth heat exchanger, a second expansion mechanism, the second heat exchanger, and the second compressor.

Heat pump

A dehumidifier is provided that may include a main body, a compressor provided within the main body to compress a refrigerant, a plurality of heat exchangers provided within the main body to condense the refrigerant compressed in the compressor or to evaporate the refrigerant, a first fan to discharge air, having undergone heat exchange with the refrigerant evaporated in the plurality of heat exchangers and having subsequently undergone heat exchange with the refrigerant condensed in the plurality of heat exchangers, out of the main body, a mode switch to perform switching between operating modes, including a cooling mode and a dehumidification mode, and a second fan to discharge air, having undergone heat exchange with the refrigerant evaporated in the plurality of heat exchangers in the cooling mode, out of the main body.
