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 clothes treating apparatus includes a filter insertion detecting device that detects whether a filter has been inserted in the clothes treating apparatus. The filter insertion detecting device, which is installed in a clothes drying machine or the like, may be moved in response to insertion of a filter assembly to generate a contact signal that indicates insertion of the filter assembly.

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.

A laundry appliance includes a camera for determining the air flow through an appliance during operation. A controller is operably coupled to the camera. The controller is configured for obtaining one or more images of an air flow indicator positioned in the path of the air flow. An artificial intelligence image recognition process is used to perform image classification and determine whether air flow through the appliance is fully or partially obstructed based on the amount of deflection of the air flow indicator. In the event of an air flow obstruction, operation of the laundry appliance is adjusted.

A laundry appliance uses a determination of a frequency of compressor temperature response, refrigerant mass flow rate, or both to determine accumulation of lint in a filter. Based on the determination, various corrective actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof.

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.

A laundry appliance uses a determination of volumetric airflow rate after a steady state condition is reached to determine the accumulation of lint in filter. Based on the determination, various actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof. One or more temperature sensors, relative humidity sensors, and weight sensors are used to provide measurements for determining the volumetric airflow rate.
