The souring of wet laundry in a laundry treating appliance may be retarded by sending an alert signal indicative of an ending of a cycle of operation from the laundry treating appliance to a remote electronic device. The appliance may receive an authorization signal from the electronic device indicative of an instruction to execute an anti-sour cycle. An anti-sour cycle comprising the energizing of a fan to flow air through a laundry treating chamber may be automatically initiated for the laundry treating appliance.

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.

A washing machine control method is provided. A washing machine has a remote control function. After the washing machine is powered off and then restarted, the remote control function is controlled to be enabled/disabled according to an unlocked/locked state of a door lock. The washing machine control method is applicable to the field of Internet of Things (Internet of Things) washing machines, and may effectively guarantee the safety of an Internet of Things washing machine in remote control and avoid occurrence of safety accidents. Meanwhile, a washing machine using the washing machine control method is further disclosed.

Washing machine technology, in which an initial speed in a drainage process is determined after a rinsing mode is finished, and a laundry distributing operation is performed in which a rotational speed of the motor is maintained at the determined initial speed. The washing machine determines whether a degree of laundry distribution satisfies an allowable range by comparing information detected by a vibration sensor with previously stored reference information. The initial speed is determined to be a rotational speed of the motor at an intersection time point at which vibration of a fundamental wave and vibration of higher harmonics detected by the vibration sensor intersect with each other.

A washing machine includes: a tub; a drum; an induction heater disposed in a position spaced apart from the drum and configured to heat the drum; an input power source; a relay configured to interrupt a current applied to the coil of the induction heater from the input power source; a first processor configured to control the relay; and a safety device connected to a circuit connecting the first processor and the relay. The safety device includes: a first thermostat configured to operate according to a temperature of a first air between the drum and the tub, and open the circuit when the temperature of the first air is a first safety control temperature; and a thermal fuse configured to operate according to a temperature of a second air outside the tub, and open the circuit when the temperature of the second air is a second safety control temperature.

Techniques are described controlling and managing machines to provide laundry services. A request may be received from a mobile device of a user, the request indicating that the mobile device is in proximity to a laundry machine such as a washer or dryer. In some cases, the request is sent by the mobile device based on detecting, at the mobile device, a wireless signal transmitted from the laundry machine. In some cases the request may include a code that identifies the laundry machine, the code being displayed by the machine and/or encoded in a scannable code displayed by the machine. In response to the request, a signal may be sent to activate the laundry machine and enable the user to use the laundry machine for a predetermined period of time (e.g., a cycle). In some cases, the activation signal is sent if the user's payment is successfully processed.

A method of controlling a washing machine that includes a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine, the method including: operating the washing motor to rotate the drum in a first rotational direction while repeatedly alternating between an acceleration and a deceleration of the drum so that laundry in the drum alternates between maintaining contact with an inner surface of the drum during acceleration, and separates from the inner surface of the drum during deceleration; and operating a circulation pump motor in the circulation pump, while the drum rotates in the first rotational direction, to accelerate a pump speed of the circulation pump during the acceleration of the drum, and to decelerate the pump speed during deceleration of the drum.
