In other words, the finishing device 10 can blow the clothes from the bottom to the top. To facilitate the drying, the finishing device 10 can pre-shake the clothes and cooperate with the drying airflow of the drying system to form an airflow in all directions to blow the clothes at the same time to prevent them from kinking and wrinkling. It can be put on after drying, without the need for a second ironing. And can speed up the drying rate.

At the same time, the fan 2 can be selected as a front, rear and middle multi-faceted air intake method. As shown in FIG. 4, a single fan 2 can have an axial first air inlet F2 and a second air inlet F3, and the first air inlet F2 and The air inlet direction of the second air inlet F3 is opposite, and may all be located in the axial direction of the fan 2. A small fan can be used while ensuring sufficient air volume. Therefore, the micro ironing function can be realized without increasing the overall product size and appearance, and the comfort of the consumer product experience can be improved.

In one specific embodiment, when the sorting device 10 is installed at a lower position, the sorting device 10 can also be optionally provided with a damper 3, and the damper 3 can be optionally installed at the air outlet F1 of the air duct 1.

Heat and mass exchange to achieve the purpose of drying clothes.

In the later stage of drying, when the moisture content of the laundry reaches a certain limit (for example, 30%), the ironing and drying mode is also turned on at the same time. In addition to the operation of the heat pump heat exchange system 20, the two fans 2 of the finishing device 10 are also turned on at the same time After starting, the baffle 5 located at the drain 4 completely closes the drain 4 and the damper 3 opens to ensure that the wind blown by the sorting device 10 circulates in the barrel and is not disturbed by the outside world. The air blown by the circulation fan is rectified by the damper 3 and then flows to the small circular hole of the inner cylinder 12 to generate acceleration behavior. The main flow direction of this air flow is vertical, which is just perpendicular to the horizontal direction of the heat pump fan system, so that the pre-dried clothes While rotating and drying with the inner cylinder 12, it receives high-speed airflow shear from the vertical direction, thereby increasing the gap between the clothes, blowing the clothes, and preventing the knots from being wrinkled with each other. When it is judged that the moisture content of the clothes meets the drying requirements of the fabric, run it for 5 to 10 minutes, to ensure the dryness and reliability of the ironing duct system.
