Provided is a multi-functional household electric iron, which comprises a housing (10), an ironing plate (20), a heating body and a disinfection device, wherein a mounting cavity (11) is formed inside the housing (10), and an opening is formed at the top end of the mounting cavity (11); the ironing plate (20) is encapsulated in the opening; the heating body is arranged in the mounting cavity (11) and is used for heating water and generating steam; a plurality of steam outlet holes (21) are formed in the ironing plate (20); the steam is led out from the plurality of steam outlet holes (21); the disinfection device is arranged at the opening and is used for disinfection when the ironing plate (20) works. The multi-functional household electric iron can perform disinfection treatment on the surface of the clothes through the disinfection device while steam ironing.
A: The present invention provides a suitcase, comprising a case body, and a cleaning mechanism mounted in the case body and capable of moving up and down, wherein the cleaning mechanism comprises a steam cleaning ring arm, and the steam cleaning ring arm is provided with multiple steam output holes. The suitcase involved in the present application has a function of cleaning and ironing clothes; during the operation of the suitcase, the clothes are hung in the case body; the cleaning mechanism moves up and down in the case body, thereby driving the steam cleaning ring arm that surrounds the periphery of the clothes to move up and down; and the steam cleaning ring arm ejects steam to the clothes by means of the steam output hole while moving up and down, so as to perform all-round cleaning and ironing on the clothes. In particular, according to the present application, in a process of cleaning and ironing the clothes, the clothes are hung in the case body, so that the case body has good stability and is not easy to fall; meanwhile, the periphery of the clothes is shielded by the case body, and therefore, the waste rate of steam is low, so that the steam can be effectively used for cleaning and ironing the clothes, and the utilization of steam is improved.
B: A steam valve (100) of a cooking appliance and a cooking appliance having the same, the steam valve (100) of the cooking appliance comprising: a valve seat (10), a valve cover (20) and a blocking portion (30); a mounting cavity (a) is provided between the valve cover (20) and the valve seat (10), and the mounting cavity (a) is provided with a steam inlet (11) and a steam outlet (21); the steam inlet (11) is disposed at the valve seat (10), and the steam outlet (21) is disposed on at least one from among the valve cover (20) and the valve seat (10); the blocking portion (30) is connected to an inner peripheral wall of the mounting cavity (a), and the blocking portion (30) is close to the steam outlet (21), at least part of the steam bypassing the blocking portion (30) and then flowing out from the steam outlet (21).
C: A clothing treatment device, comprising a housing (1), at least a clothes drying apparatus (2) being arranged in the housing, the clothes drying apparatus comprising a drying air duct (4) and a heat exchange element (5) for implementing heat exchange with the drying air in the drying air duct; and also comprising a steam generating apparatus (8), the condensation water of the heat exchange element producing water vapour by means of the steam generating apparatus and then entering a clothes drying drum (3) of the clothes drying apparatus by means of the drying air duct. The clothing treatment device implements full recovery and reuse of the condensation water of the heat exchange element, the recovered condensation water being used as the water source of the steam generating apparatus, and the produced steam ironing the clothing during clothes drying, such that the clothing is flat and smooth, and can also achieve better cleaning and disinfecting effects. The steam produced by the steam generating apparatus enters the clothes drying drum via the drying air duct, and good uniform diffusion can be achieved without the need to add additional drive force.
D: Disclosed is a multifunctional steam iron, which is constituted of the following parts: a steam generation unit (4), which produces steam and discharges same from a steam discharge orifice (11) of a bottom plate (1); a cleaning and dedusting unit used for cleaning dust from the surface of clothes; a dust absorption unit used for absorbing and storing dust; a sterilization and deodorization unit used for killing bacteria on the surface of the clothes and eliminating peculiar smells; a control unit (5), comprising a power source, a steam generating circuit, an ultrasonic generating circuit, an electrostatic generating circuit, an ozone generating circuit and an ion generating circuit; a bottom plate (1), which is provided with the steam discharge orifice (11), an ozone discharge opening (13), a dust absorption opening (12), a second heating element (14) and a temperature sensor (15); and a housing (2).
