Third embodiment

The present embodiment is also the most preferable embodiment of the present invention, and as shown in fig. 3, in combination with the first embodiment and the second embodiment, the air duct 4 and the drum 3 have the air duct heat receiving unit 401 and the drum heat receiving unit, respectively, and the electromagnetic heating module 6 for heating the air duct heat receiving unit 401 and the drum heat receiving unit is provided in the casing 1, respectively.

Specifically, as shown in fig. 3, in the laundry treatment apparatus according to the present embodiment, the air duct 4 and the drum 3 are provided with the air duct heat receiving unit 401 and the drum heat receiving unit, respectively, the casing 1 or the air duct 4 is provided with the electromagnetic heating module 6 for heating the air duct heat receiving unit 401, and the outer tube 2 is also provided with the electromagnetic heating module 6 for heating the drum heat receiving unit. The electromagnetic heating module 6 heats the air duct 4 and the roller 3 at the same time to heat the circulating air flow in the circulating air duct, so that the clothes in the roller 3 are heated more quickly, and the drying efficiency is higher.

In this embodiment, the structures, the positions, and the manners of the air duct heated part 401, the drum heated part, and the electromagnetic heating module are the same as those set in the first and second embodiments, and thus the description thereof is omitted.

In this embodiment, the air duct 4 and the roller 3 are respectively provided with an air duct heated portion and a roller heated portion, the electromagnetic heating modules 6 are correspondingly and respectively arranged in the housing 1 and on the outer barrel 2, and the electromagnetic heating modules 6 simultaneously heat the air duct 4 and the roller 3, so that the clothes in the barrel are heated more quickly, and the drying efficiency is higher. The problem of current dryer or washing and drying all-in-one with heating device setting inside the wind channel, long-time can cause heating device's position to store up a large amount of lines bits, not only is difficult to clear up, breeds the bacterium, the line bits are piled up more and can be influenced the stoving effect has not only been solved. And set up electromagnetic heating module on the urceolus, to the all-in-one washer dryer, still realized that electromagnetic heating module possesses the purpose of the dual efficiency of the interior washing water of heating cylinder and the interior clothing of drying cylinder simultaneously, promoted the washing effect and the drying efficiency of all-in-one washer dryer.
