An automated ironing apparatus has a flexible steaming head for applying steam to a supported article. The flexible steaming head includes a device for shaping the flexible steaming head in at least two dimensions. A method of operating this apparatus for smoothing a garment includes a step of closing at least one opening in the garment, thereby to restrict gas flow through the at least one opening and introducing gas inside the garment thereby to smooth the garment. The step of closing at least one of the openings to be closed is effected by engaging the flexible steaming head with a surface of the garment.

The present disclosure relates to an intelligent positive and negative pressure system and an operation method therefor, and an intelligent positive and negative pressure electric appliance. The system comprises a positive and negative pressure intelligent fresh-keeping refrigerator, a positive and negative pressure intelligent washing machine, a positive and negative pressure dish washing and fruit and vegetable cleaning machine, a positive and negative pressure range hood, a positive and negative pressure baking and frying microwave oven, a positive and negative pressure fresh-keeping compartment container, a positive and negative pressure fresh-keeping warehouse, a positive and negative pressure disinfection machine, and a positive and negative pressure module cabinet. By means of the positive and negative pressure system, a fluid and a carried substance thereof are regulated and controlled by means of positive and negative pressure, so as to affect an object in a specific space in a targeted manner.

In one embodiment, a washer-dryer system includes a fuel cell unit configured to generate electrical power and steam, a motor configured to receive electrical power from the fuel cell unit, a heat exchanger configured to receive steam from the fuel cell unit and configured to generate heated air and heated water, a rotatable drum configured to receive at least one of the heated air and the heated water from the heat exchanger, and a drive shaft coupled to the motor and the rotatable drum. In one embodiment, the washer-dryer system further includes a control unit configured to control operation of the motor such that the motor causes the drive shaft and the rotatable drum to rotate at a predetermined rotational speed.
