A system for monitoring sanitation agents in a laundry machine comprises a plurality of channels. Each channel has an input port, an output port, and a glass tube. Each input port and output port is adapted to be fluidly coupled to the laundry machine. The system includes a monitoring unit associated with each of the glass tubes. Each monitoring unit includes a bubble detector and a flow rate measurement unit. A beeper is configured to generate an indication of an alarm condition based on a determination made by any one of the monitoring units. The system has a display screen, a memory storing computer-readable instructions, and a controller communicatively coupled to each of the monitoring units. The controller is configured to execute the instructions to wirelessly communicate to a web page a volume of a sanitation agent that has passed through each of the glass tubes.

Disclosed is a home appliance system including a home appliance and a mobile terminal. The home appliance includes a tag unit, a communication unit, a memory, a display unit, an input unit, a drive control unit and a controller to control general operations of the home appliance, the home appliance including a washing machine. The mobile terminal includes a communication unit, a storage unit, a display unit, an input unit, a speaker and a terminal controller.

A washing machine with a liquid additive supply device capable of sensing an amount of liquid additive contained therein. A buoyancy body and a sensing unit are disposed in a reservoir tank of the liquid additive supply device. The vertical position and therefore the distance between the buoyancy body and a sensing unit vary with the surface level of liquid additive in the reservoir tank due to buoyancy effect. The buoyancy body may include a magnetic body and the sensing unit can detect the intensity of the magnetic body. The surface level of the liquid additive is too low, the sensing unit can generate a signal indicative of liquid additive shortage.

A drying machine for drying clothing includes: a housing; a drum configured to receive clothing; a guide apparatus for guiding air in a path through the drum; an air moving apparatus to pull air through the guide apparatus and drum; a heating apparatus for heating air and having on and off conditions; a heat capacitor for storing and releasing heat to air when the heating element is in its off condition and the drum is rotating; power means for components of the drying machine; including at least the drying compartment assembly, rotation means, guide apparatus, air moving apparatus, heating apparatus, and control apparatus; a control apparatus for controlling at least one of the drying compartment assembly, the rotation means, guide apparatus, the air moving apparatus, the heating apparatus, and the power means; and restrictor means for restricting the air flow whereby the drum pressure is lower than ambient air pressure.

A domestic laundry-washing appliance including an optical measuring device for obtaining measured values which are representative of a spectral transmission signature of a washing liquid used during operation of the laundry-washing appliance for cleaning textiles, and a control device which is adapted to categorise a cleaning agent contained in the washing liquid in respect of its chemical properties on the basis of the spectral transmission signature obtained, and to control the operation of the laundry-washing appliance in dependence on the categorisation result. The categorisation result can indicate, for example, a distinction between a heavy-duty detergent containing bleach and another bleach-free detergent.

The invention relates to a condenser tumble dryer with a drum for articles to be dried, a drive motor for the drum, a process air duct, a process air blower, a heating and cooling system for the process air, a temperature sensor and a control device. The temperature sensor is an infrared telescope and is arranged to simultaneously measure heat radiation from at least two components of the condenser tumble dryer which are to be monitored. The invention also relates to a method for operating a condenser tumble dryer of said type.

A laundry appliance includes a camera for determining whether the drum is rotating during operation of the appliance. A controller is operably coupled to the camera. The controller is configured for obtaining one or more images of the drum during operation of the appliance. An artificial intelligence image recognition process is used to perform image classification and determine whether a drum rotation fault has occurred. In the event of a drum rotation fault, operation of the laundry appliance is adjusted.
