The cleaning device of this embodiment is drum washing machine 1, including being used for the cylindrical ventilation pipe 2 of a section of intercommunication external environment and washing machine 1 inner chamber 14, ventilation pipe 2's air inlet end is provided with filter 3, for example filter screen, filter cotton etc. can realize carrying out the part of filtering to the dust particulate matter in the air, thereby make the air that gets into ventilation pipe 2 is the air of purification, ventilation pipe 2's air-out end is provided with fan 4, ventilation pipe inside is equipped with filter and ionizer along the air inlet direction in proper order, this embodiment be provided with ionizer between fan 4 and the filter 3, ionizer will pass through ventilation pipe 2's air, and fan drive air gets into through the ventilation pipe the cleaning device inner chamber for contain a large amount of ions in the air that lets in washing machine 1 inner chamber 14, these ions are favorable to the disinfection of disinfecting to the clothing, when ventilation pipe 2's air outlet end and washing machine 1 inner chamber 14 communicate, thereby make the air current get into inner chamber 14, in the inner chamber 13 in that makes the inner chamber that the inner chamber flows through 13, thereby realize the disinfection to the clothing that takes away simultaneously.

As shown in fig. 3, in order to increase the ion concentration, a multi-stage ion generator may be provided along the ventilation pipe 2, and in this embodiment, a two-stage ion generator is provided, which is a first-stage ion generator 5 and a second-stage ion generator 6, respectively.

Further, the ionizer may be a negative ionizer or an ozone generator according to different disinfection requirements.

As shown in fig. 4, the fan 4 and the filter 3 are both disposed in a pipeline, and an electrical connection port 7 for connecting an external power supply is disposed at an end of the pipeline, and the electrical connection port 7 is electrically connected with the fan 4 and the ionizer, so as to electrically supply power to the fan 4 and the ionizer.

The washing machine 1 is provided with a mounting hole 8 slightly larger than the ventilation pipe 2, the detachable plug-in mounting of the fresh air device is arranged in the mounting hole 8, the mounting hole 8 is provided with a power supply port 9 corresponding to the power connection port 7, when the fresh air device is plugged in the mounting hole 8, the power connection port 7 is electrically connected with the power supply port 9, and the power supply port 9 is connected with an external power supply, so that power supply to the fan 4 and the ion generator of the fresh air device is realized. The ventilation pipe 2 is inserted into the mounting hole 8 to realize the communication between the air outlet end of the ventilation pipe 2 and the inner cavity 14 of the washing machine 1, as shown in fig. 6, the air outlet end of the ventilation pipe 2 is communicated with the inner cavity 14 of the washing machine 1 through an air inlet channel 10 which is approximately tangential to the inner cavity 14 of the washing machine 1.

As shown in fig. 5 and 7, the inner cavity 14 of the washing machine 1 is communicated with an exhaust port 11, the exhaust port 11 is provided with a control valve 12, when the air is required to be exhausted, the control valve 12 is conducted, and the air can be exhausted, otherwise, the air is in a closed state.

Specifically, when the inner cylinder of the washing machine accelerates to 93 revolutions per second at 5 revolutions per second in the process of introducing fresh air, if the detected eccentricity is smaller than the eccentricity value of the set value, the inner cylinder decelerates to 0 revolution at 5 revolutions per second after maintaining at least 30 seconds per second at 93 revolutions per second. If the detected eccentricity is larger than the set eccentricity value, the inner cylinder reversely rotates, the acceleration of the reverse rotation is 5 revolutions per second, and the acceleration is accelerated to be larger than 60 revolutions per second and then the speed is reduced to 0 revolution. And repeating the first process until the fresh air process is ended and exits.

The fresh air device is characterized in that the high-density filter screen intercepts large-particle impurities in air, and cleaner air is obtained after first-stage ionization and second-stage ionization. At this time, air is introduced into the inner tube 13, and the air in the inner tube 13 is replaced. Meanwhile, the inner cylinder 13 rotates regularly to stretch clothes, dust and bacteria on the clothes are combined into macromolecular particles through ions in the air, and the air of the inner cylinder 13 is discharged through an air outlet arranged on the rear cylinder of the washing machine 1. The electronic reversing valve is arranged in the air outlet, and is conducted when air is required to be exhausted, and air exhaust can be performed, or the air outlet is in a closed state.
