Abstract: Disclosed herein is a heat pump type dryer for reducing the manufacturing cost thereof and maintaining an appropriate quantity of radiation by auxiliary heat exchanger. The clothes dryer D includes housing 1; drum portion 2 installed in the housing 1 and configured to accommodate clothes; a circulation ventilation path 3 configured to pass through the drum portion 2; a heat pump apparatus 5 having a compressor 52, a condenser 53, a throttling device 54, and an evaporator 51, connected to form a flow path through which refrigerant circulates; an auxiliary heat exchanger 55 installed outside the ventilation path, and connected in series to a flow path in the condenser 53 or in parallel to the condenser 53; and a cooling apparatus 6 configured to cool the auxiliary heat exchanger 55.

Abstract: The clothes dryer of the present disclosure includes a circulation air flow path communicating with the drum, a condensed water storage chamber communicating with the circulation air flow path and a pump chamber communicating with the condensed water storage chamber. The communication path introduces air into at least one of the first circulation air flow path and the pump chamber to reduce the pressure of the pump chamber by introducing air into the pump chamber or to introduce air into the condensed water storage chamber through the first circulation air flow path. Accordingly, there is an effect of increasing the air volume of the fan device while preventing backflow and scattering of the condensed water caused by dehumidification in the clothes dryer.

Abstract: A heat pump type clothes dryer compensates for pressure loss caused by a radiator to increase the flow rate of air passing around the radiator, and suppressing introduction of ambient air through gaps formed in air flow lines to avoid degradation in drying capacity, while avoiding an increase in the power consumption or noise of a fan. The clothes dryer includes a drum to accommodate clothes, an air suction or intake line to suck air into the drum, an air exhaust line to exhaust air from the drum, a heat pump circuit including a compressor, a radiator, a pressure reducer, and a heat absorber, where the heat absorber is provided in the air exhaust line, and the radiator is provided in the air suction or intake line, a first blowing mechanism provided in the air exhaust line, and a second blowing mechanism provided in the air suction or intake line.

Abstract: An air conditioner having an improved humidifying portion to humidify air in a room is provided. The humidifying portion includes a humidifying member having hygroscopicity and gas permeability, a first air flow passage for taking in air from the outdoors, passing the air through the humidifying member, allowing the humidifying member to absorb moisture included in the air for drying, and letting out the air outdoors, and a second air flow passage for taking in air from the room, passing the air through the humidifying member while heating the air, allowing the moisture absorbed by the humidifying member to evaporate and humidify the air and letting out the air into the room. Thus, only a single air intake opening for humidifying indoor air is necessary on the indoor side, the structure of the air conditioner can be simplified and compact, which makes easier the attachment.
