Title: VENTED HEAT PUMP DRYER
Abstract:
A vented heat pump dryer, comprising: an outer drum, and an air-intake drying air duct (2) and an air-exhaust drying air duct (3) which connect the outer drum (1) to the outside respectively. The dryer is also provided with a heat pump system. A condenser (4) of the heat pump system is provided in the air-intake drying air duct (2), and an evaporator (5) is provided in the air-exhaust drying air duct (3). The air-exhaust drying air duct (3) comprises at least two branches of which the opening and closing are controllable. Each branch is provided with a corresponding evaporator (5). The dryer enables an exhaust air stream to flow through different branches at different drying stages independently or at the same time, therefore adjusting the working states of the heat pump reasonably and increasing the drying efficiency of the dryer.
