A laundry treating apparatus includes a cabinet with first and second cabinet doors. A first washing apparatus processes laundry that is placed through the first cabinet door at the front. A second washing apparatus processes laundry that is placed through the second cabinet door at the top. The second washing apparatus includes: a tub that holds water and has an opening at a top that is accessible through the second opening of the cabinet; a tub cover that covers the top of the tub and defines an inlet through which the tub is accessible; a tub door on the tub cover that opens or closes the inlet of the tub cover separately from the second cabinet door opening or closing the second opening; a drum inside the tub configured to rotate about a vertical shaft; and a first sensor that generates a signal based on the tub door being open.

An automated system and method for providing sanitary towels in restaurants and bars includes a tank assembly, a perforated drum assembly, a drive motor and drive gear assembly, a sanitizer solution source, a water source, a heating unit, one or more solenoid valves capable of governing the introduction and release of water and sanitizer solution into and from the tank assembly, one or more sensors capable of measuring solution temperature and sanitizer concentration, and a controller unit having at least one processor and memory. A method of use involves the programmable steps of filling the tank assembly, measuring the concentration of sanitizer, adjusting the concentration of sanitizer, measuring the temperature of the water and sanitizer solution, adjusting the temperature, agitating towels, and draining the water and sanitizer solution after a preferred amount of time.

A laundry treatment apparatus is disclosed. The laundry treatment apparatus includes a cabinet, a tub arranged in the cabinet, a drum arranged in the tub and formed of a metal material, and an induction module configured to inductively heat the drum, wherein the induction module includes a coil formed by winding a wire, and a base housing including a base body arranged on the tub, and a fixing rib arranged on the base body to fix coil, wherein the wire is drawn into the base body in one direction, wound around the fixing rib, and drawn out of the base body in the same direction.

The present invention relates to a laundry care apparatus in which an induction module heats the drum uniformly using a magnetic field to dry laundry or heat wash-water, and center and front and rear regions of the drum are uniformly heated.

A laundry treatment apparatus is configured to directly heat a drum containing laundry therein. The laundry treatment apparatus includes: a tub; a drum configured to rotate within the tub and to contain laundry therein, the drum being formed of a metallic material; and an induction module provided at an outer surface of the tub and configured to heat a surface of the drum within the tub via induction, the induction module comprising: a coil that comprises a wire through which an electric current is configured to pass so as to generate a magnetic field; a base housing configured to accommodate the coil therein, the base housing being mounted on the outer surface of the tub; an at least one magnet configured to be arranged above the base housing in which the coil is accommodated, and arranged to be lengthwise perpendicular to a longitudinal direction of the wire of the coil.

A washing machine includes: a tub; a drum; a temperature sensor configured to detect a temperature of air between the drum and the tub; an induction heater configured to heat the drum; a controller unit configured to control the induction heater within a preset control temperature range; a circuit configured to supply power to the induction heater; a first thermostat configured to operate according to a first temperature of air between the drum and the tub and open the circuit when the first temperature is a first safety control temperature; and a thermal fuse configured to operate according to a second temperature of air outside the tub and open the circuit when the second temperature is a second safety temperature corresponding to a case where the temperature of the drum is in a second safety temperature range having a larger value than the first safety temperature range.

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.
