An ozone production method and system for producing ozone which comprises a plurality of washing machines, an ozone generator for generating ozone, and an ozone supply conduit for supplying ozone from the ozone generator to the washing machines. Each washing machine has a respective venturi, located between a water source and an inlet to the washing machine. The venturi is connected to the ozone supply conduit so that, as water flows through the respective venturi, such water flow creates a negative pressure within the ozone supply conduit. At least one sensor is located so as to detect the negative pressure created within the ozone supply conduit. The at least one sensor is connected to a control box, coupled to the ozone generator, which controls ozone production of the ozone generator depending upon the negative pressure generated within the ozone supply conduit.

Disclosed herein is a laundry machine. More particularly, a laundry machine for generating steam by an induction heater and a control method thereof are disclosed. According to an embodiment of the present disclosure, provided is a method of controlling a laundry machine including a tub, a drum rotatably arranged in the tub to accommodate an object and provided with a through hole on an outer circumferential surface thereof, and an induction heater provided to the tub, and configured to perform a steam operation. The steam operation may include heating a heating surface of the drum facing the induction heater by driving the induction heater, spraying, through a spray nozzle, water toward the heating surface heated in the heating operation, and rotating the drum such that the steam is introduced into the drum through the through hole in a space between the tub and the drum.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A water supply adds water to the wash tub during a fill cycle and a camera assembly is used to monitor the water level. Specifically, the camera assembly obtains one or more images of the wash chamber during and/or after a fill cycle and a controller analyzes the images using a machine learning image recognition process to determine when the water within the wash tub has reached a predetermined water level, e.g., optimized based on load size or other load parameters. If the water in the wash tub is below or above the predetermined water level, the controller may implement responsive action, e.g., by adjusting at least one operating parameter of the washing machine appliance.
