Embodiment Construction
[0042] figure 1 It is a schematic structural diagram of a clothes dryer according to an embodiment of the present invention, and the arrows in the diagram indicate the air flow direction. see figure 1 The clothes dryer 10 of the embodiment of the present invention may generally include a casing 11, a drum 12 arranged in the casing 11 for accommodating clothes to be dried, a driving mechanism (not shown in the figure) for driving the rotation of the drum 12, and further The wind channel 14, the heating device 27 and the exhaust channel 15. The air intake channel 14 is configured to introduce air from the environment outside the clothes dryer 10 into the drum 12 . Generally, a fan 21 can be arranged in the air inlet channel 14, and is configured to blow air from the environment outside the clothes dryer 10 to the drum 12.
[0043] The heating device 27 is arranged in the air inlet channel 14 and is configured to heat the air flowing through it to form hot air whose temperatur...

The invention provides a clothes dryer. The dryer comprises a roller used for holding to-be-dried clothes, an air inlet channel configured to guide air from the external environment of the clothes dryer to the roller, a heating device arranged in the air inlet channel and configured to heat air flowing through the channel in order to form hot air with temperature higher than the ambient environment, an air exhaust channel configured to exhaust hot air to the external environment of the clothes dryer after flowing through the roller, as well as a heat-exchanging device comprising a heat absorption part, and a heat releasing part. The heat absorption part is arranged in the air exhaust channel to absorb heat from hot air of the air exhaust channel. The heat releasing part is arranged in the air inlet channel and located at the upstream of the heating device so that heat absorbed by the heat absorption part is utilized to pre-heat air of the air inlet channel before the air reaches the heating device. The clothes dryer makes full use of heat energy of hot and humid air so that utilization rate of heat energy is improved, thereby reducing heating power of the heating device and reducing energy consumption.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to an exhaust type clothes dryer. Background technique [0002] The clothes dryers or exhaust type clothes dryers currently on the market generally use hot air to blow through the wet clothes, so that the water on the wet clothes evaporates into water vapor and is directly discharged into the external environment of the clothes dryer along with the airflow. Existing clothes dryers have at least the following problems: the discharged hot and humid gas still has a relatively high temperature, and it is directly discharged to the environment without any recycling, which causes waste of heat energy on the one hand, and discharges heat and water vapor into the air on the other hand will affect the environment. Contents of the invention [0003] An object of the present invention is to overcome at least one defect of the prior art, and provide a clothes dryer that fully ut...
