A washing machine includes a cabinet; a tub in the cabinet; and a detergent supply apparatus which supplies detergent to the tub and includes: a housing; a detergent box configured to be inserted into the housing and thereby docked to the detergent pump so that detergent in the detergent box is suctionable by the detergent pump and then dischargeable by the detergent pump into the housing and configured to be withdrawn from the housing and thereby undocked from the detergent pump; and an auxiliary tank which in the housing, configured to store water, and to, when the detergent box is being withdrawn from the housing, drain water stored in the auxiliary tank to a bottom of the housing so that detergent from the discharge pump falls into the water on the bottom of the housing.

A method of operating a laundry treating appliance having a tub with a terminal edge and a dual-wall basket, with outer and inner walls, the inner wall having perforations above the terminal edge, and the basket located within the tub and having at least one drain opening in a bottom of the basket. The method comprising altering a level of liquid in the tub to correspondingly alter a height of a float valve in the tub to selectively open/close the drain opening to effect a filling of liquid in the basket above the tub terminal edge when the float valve is in the closed position.

A washing machine capable of operating in an IoT environment through a 5G communication network and estimating the type and amount of injected detergent through a neural network model created according to machine learning, and a method of controlling the washing machine, are provided. The washing machine may include a first tub into which laundry is loaded, a water supplier configured to supply washing water to the first tub, a detergent detection sensor configured to detect first conductivity and first turbidity of the washing water, and a processor configured to determine a washing cycle of the washing machine based on detected information.

A fabric treating appliance includes a rotatable basket defining a treating chamber for receiving a load of laundry items for treatment. A float valve can be incorporated into the basket structure, selectively opening or closing the valve based upon the liquid level in a tub. As liquid fills the tub, the float valve will rise until it moves into a closed position, permitting the basket and treating chamber to fill with liquid. As the tub drain, the float valve can fall, opening the valve and permitting liquid to drain from the basket or treating chamber. The opened or closed positions can be selectively operated by opening or closing a pump or sump and allowing a tub to drain or fill, respectively.

A method for operating a laundry washing machine comprising a washing tub external to a washing drum, a recirculation system comprising a recirculation circuit configured to drain liquid from the bottom of the washing tub and to re-admit such liquid into the washing tub, a liquid level sensor device configured to detect the liquid level inside the washing tub, and a variable speed recirculation pump connected to the recirculation circuit. The method comprises a recirculation phase comprising controlling the recirculation pump by varying the rotation speed of the recirculation pump depending on a difference between the detected liquid level and a prefixed liquid level value.

A laundry washing machine having a washing tub external to a washing drum configured to receive the laundry to be washed, a recirculation system having a first duct to circulate liquid into a first region of the washing tub and a second duct to circulate liquid into a second region of the washing tub. The recirculation system comprises a recirculation pump operable in a first direction of rotation and in a second direction of rotation opposite to the first direction. The recirculation pump is operated in the first direction to circulate liquid in the first duct and is operated in the second direction to circulate liquid in the second duct.

A laundry washing machine having a washing drum, a washing tub external to the washing drum and a recirculation system having a first duct terminating at a first region of the washing tub and a second duct terminating at a second region of the washing tub. The recirculation system comprises a recirculation pump for conveying liquid to a bifurcation for the first duct and the second duct. The recirculation pump has a first functioning condition wherein liquid circulates only in the first duct and a second functioning condition wherein liquid circulates both in the first and second ducts.

A washing machine drainage structure for a washing machine, in which there is not water between an inner tub and an outer tub in washing and rinsing processes, includes comprises a ball valve and a driving device for controlling opening and closing of the ball valve, a drainage outlet is arranged at a bottom wall of an inner tub, a water inlet end of the ball valve is communicated with the drainage outlet, and the ball valve is driven by the driving device to be closed in the washing and rinsing processes and opened in draining and dehydrating processes. According to the drainage structure, the ball valve is driven by the driving device to be closed or opened so as to close or open the drainage outlet, thereby implementing drainage; and the drainage structure has a simple structure and is convenient to be mounted.
