The shell 411 is divided into the atomizing cavity 42 and the mounting cavity 43 by the partition 417, and the controller 47 is arranged in the mounting cavity 43 and is respectively connected with the driving circuit board 441, the driving part 451 and the fan 48, so that the atomizing generator 4 of the invention realizes high integration, the controller 47 can simultaneously control the start and stop of the ultrasonic atomizing sheet, the driving part 451 and the fan 48, the respective wiring of the components is avoided when the washing machine is assembled, and the assembly efficiency is improved. Set up fan 48 between controller 47 and air intake 4111 to fan 48's inlet scoop corresponds the setting with air intake 4111, and the air outlet sets up towards baffle 417, and baffle 417 sets up opening 4171 corresponding to controller 47's position, can also be when atomizing generator 4 during operation, and the air current that utilizes atomizing generator 4 during operation flows through controller 47 and dispels the heat for controller 47, thereby improves controller 47's working life and job stabilization nature.

Through setting up the intercommunication chamber on first lid, and set up fog outlet 4113 in the casing 411 bottom surface, and then use communicating pipe with fog outlet 4113 and second intercommunicating pore 4142 and connect for form a complete air current passageway between installation cavity 43, atomizing chamber 42, the intercommunication chamber and the communicating pipe, adding fan 48's effect, make the discharge of water smoke powerful naturally. The mist outlet 4113 is arranged on the bottom surface of the shell 41, so that the mist outlet 7 can be conveniently connected with the outer barrel 3 without bending, the spraying stroke of the mist is shortened, and the spraying effect of the mist is improved. The bottom surface of the transverse rib plate 414 corresponds to the notch 4171 and extends the wind shield 4143, so that the wind blown out by the fan 48 bypasses through the notch 4171, the carrying effect of the wind on the water mist is improved, the purpose of quickly discharging the water mist is achieved, and the situation that the water mist is remained in the atomizing cavity 42 due to the fact that the wind is blown out is avoided. Set up the ultrasonic atomization piece in casing 411 outside through atomization piece support 416 sealedly to and set up the through wires hole in installation cavity 43, make the line of control line 472 not pass through atomization chamber 42, avoided control line 472 and water contact and the appearance of the safety problem that leads to, improved atomizer 4's security.

The atomization element 44 is an ultrasonic atomization sheet, the atomization generator 4 breaks up the liquid water molecule structure to generate naturally drifting water mist through high-frequency resonance of the atomization sheet by utilizing electronic high-frequency oscillation (oscillation frequency is 1.7MHz or 2.4MHz and other frequencies exceeding the hearing range, and the electronic oscillation has no harm to human bodies and animals), the water mist is atomized into 1-100 micron ultramicro particles, and the atomization is uniform without heating or adding any chemical reagent. Compared with the heating atomization mode, the energy is saved by 90 percent. In addition, a large amount of negative ions are released in the atomization process, and the negative ions and smoke, dust and the like floating in the air generate electrostatic reaction, so that the negative ions are precipitated, harmful substances such as formaldehyde, carbon monoxide and bacteria can be effectively removed, and micron-sized water molecules can be adsorbed on clothes more quickly, so that the clothes care experience is better.

Through set up the intercommunication chamber in atomizer 4 and set up valve mechanism 45 in the intercommunication intracavity, can promote washing machine's operation security greatly, effectively avoid drying module 5 when starting damp and hot air to atomizer 4 and washing machine inside and the condition appearance that leads to and electrical component wet the short circuit against the current. Specifically, by providing a communication chamber in the housing 41, which is independent from the atomizing chamber 42, and communicating the atomizing chamber 42 with the mist outlet 4113 through the communication chamber, the communication chamber becomes a necessary passage for the water mist to reach the mist outlet 4113 from the atomizing chamber 42. And the intercommunication intracavity is provided with valve mechanism 45, valve mechanism 45 can seal the mode of setting of first intercommunicating pore 4141 and second intercommunicating pore 4142, make valve mechanism 45 can cut off this passageway completely to prevent outside air current from in the fog outlet 4113 flows against to atomizing generator 4, especially when washing machine's drying module 5 starts, can block that humid air in the washtub flows against to atomizing generator 4 and then discharges to washing machine inside from air intake 4111, the condition of faults such as the electric component in atomizing generator 4 and the washing machine wets the short circuit has been avoided appearing, washing machine's operational safety has greatly been improved. Moreover, the arrangement mode has high feasibility and outstanding effect, and is favorable for large-scale popularization and use.
