  • Publication number: 20190368098
    Abstract: An integrated laundry care machine and an operating method thereof. The integrated laundry care machine comprises a housing (1), and a washing system (2) and a care system (3) disposed in the housing (1). A collapsible support plate (4) is disposed between the washing system (2) and the care system (3). After being expanded, the support plate (4) can be ascended or descended along a height direction of the integrated laundry care machine. The support plate (4) is provided to hold clothes taken out from the washing system (2), and transfer, towards the care system (3), the clothes taken out from the washing system (2), facilitating an increase in operating efficiency of transferring clothes from the washing system (2) to the care system (3), and reducing labor intensity.

  • Publication number: 20190194860
    Abstract: A washing and drying integrated machine comprises a housing; a drying drum assembly configured to dry clothes and a washing drum assembly configured to wash clothes, which are respectively arranged inside the housing and operate independently. The washing and drying integrated machine further comprises a heating device, wherein the heating device is respectively connected with a drying drum in the drying drum assembly and a washing drum in the washing drum assembly via ventilating ducts. The same heating device provides hot wind to the inside of the drying drum and the inside of the washing drum. Opening or closing of valves on the ventilating ducts between the heating device and the drying drum as well as the washing drum, provide separate or simultaneous supply of heat to the drying drum and the washing drum, thereby realizing multiple purposes of the heating device.

  • Patent number: 10233582
    Abstract: A control method of a double-drum washing machine, having a first washing drum and a second washing drum. Whether the heating time required by the first drum is overlong is judged before the first drum performs heating. If yes, the second drum executes the heating, or dewatering, or drying processes. If not, the following steps are performed: judging whether the second drum performs heating; if yes, judging whether the remaining heating time of the second washing drum is greater than T0; if the judgment result is yes, executing the alternate heating program that the first drum and the second washing drum perform heating alternately, and if the judgment result is no, executing the ordered heating program that the second drum performs heating firstly, and then the first drum performs heating, wherein T0 is a time value for judging whether the heating of the second drum is about to finish or not.
