Description
Technical Field

Background
Laundry drying apparatuses (e.g., clothes dryers, clothes washers, etc.) generally include a laundry receiving drum for receiving laundry to be dried and a drying duct external to the laundry receiving drum and communicating with the laundry receiving drum for blowing a drying air flow into the laundry receiving drum through the drying duct. When the drying airflow flows through the clothes containing drum, the moisture remained on the clothes in the clothes containing drum is heated into water vapor, and the water vapor flows out of the clothes containing drum along with the air to enter the drying channel and is condensed at the upstream section of the drying channel. The condensed relatively dry air continues to flow along the drying channel and re-enters the laundry-receiving drum for continuous circulation. The existing washing and drying machine is of a general water condensation type, for the water condensation mode, cold water needs to be continuously introduced into a drying channel in the clothes drying process, and meanwhile, in order to save water as much as possible, the flow of the cold water introduced into the drying channel needs to be controlled to be small, so that the condensation mode is low in condensation efficiency and high in water consumption. For the air condensation mode, the heat exchange between the air at the room temperature outside the machine and the humid and hot air in the drying channel is needed in the clothes drying process, and because the heat is needed to be exchanged through the pipe wall in the mode, the condensation efficiency is quite low, the clothes drying time is longer, and the energy consumption is higher.

However, this device has the following disadvantages:
first, although the semiconductor refrigeration chip has two functions, i.e. both cooling and heating, the refrigeration power of a single refrigeration element of the semiconductor refrigeration chip generally needs to be composed of a plurality of units to meet the condensation requirement, which increases the manufacturing cost or energy consumption.
In addition, in order to further improve the condensation effect, some clothes drying devices only utilize the heating function of the semiconductor module, a condensation device is separately arranged in the circulation channel, and the condensation device must rely on a cold source (such as electric drive and the like) to realize the refrigeration effect, for example, the Chinese patent application with the application number of 201210008372.X discloses a novel clothes dryer which comprises a shell and an inner cylinder, and also comprises an air duct, a semiconductor refrigeration sheet, a condenser and an evaporator; the inner barrel is communicated with the air duct through a communicating pipe assembly, the condenser and the evaporator are both located in the air duct, the hot end of the semiconductor refrigeration piece is connected with the condenser through a first heat exchange pipe, the cold end of the semiconductor refrigeration piece is connected with the evaporator through a second heat exchange pipe, a driving device enabling air in the communicating pipe assembly, the air duct and the inner barrel to flow is arranged on the communicating pipe assembly, and a water removing pipe is arranged on the air duct in a communicated mode.
