A household dishwasher includes: a washing water spray nozzle module disposed on an area of inner surfaces of a washing chamber and spraying washing water, which is supplied from a water supply tube, into the washing chamber; a steam generation module disposed in the washing chamber and supplying steam into the washing chamber using the washing water supplied from the washing water spray nozzle module; an induction module disposed on an outer surface of the washing chamber and heating the washing water supplied in the washing chamber; an ultrasonic vibration module disposed on an outer surface of the washing chamber and applying ultrasonic vibration to the washing water in the washing chamber to perform ultrasonic washing; and a controller disposed in a body and controlling operational relationships of internal components in response to washing order signals from a user.

A dishwasher, in particular a household dishwasher, includes a mechanism for modifying odor. The mechanism for modifying odor includes an ozone generator for odor neutralization in a dishwasher cavity and a system for fragrance introduction into the dishwasher cavity. A control device has stored therein a process, which firstly provides for the odor neutralization by the ozone generator and then introduction of a new fragrance by the system for fragrance introduction.

A system for dosing substances such as cleaning and/or care agents is disclosed. The system includes a dosing device, at least one energy source, a control unit, a sensor unit, and at least two cartridges for respectively accommodating at least one of the cleaning and/or care agents. The at least two cartridges are capable of being coupled to the dosing device.

In embodiments, the invention includes a system, an apparatus, and a method for cleaning reusable straws. The system includes a chamber configured to contain a liquid, a siphon to drain the chamber, a transducer to deliver sonic energy to the chamber, and a plurality of straws disposed in the chamber. Each straw includes a tubular wall defining a lumen. The lumen has a length and a cross-sectional area, and the cross-sectional area is substantially constant over the length.

A beverage container washing system may utilize a heated wash fluid circulation system to circulate wash fluid retained in a line between a tank and a sprayer to enable fluid that is supplied to the sprayer to be maintained at a suitable temperature for washing and/or sanitizing a beverage container, and in many instances regardless of the amount of time between wash cycles.

A method and system are provided that include features for operating an appliance in an odor removal cycle. In one aspect, an appliance has a housing defining a sealable volume and includes an ozone generator, an ozone detection device, and a controller. In an odor removal cycle, the controller causes the ozone generator to inject, at a predetermined injection interval, predefined dosages of ozone into the sealable volume of the appliance. The controller monitors the concentration level within the sealable volume after each injection based on inputs received from the ozone detection device. The controller ascertains when the concentration level reaches a maximum concentration level threshold, and when this occurs, the controller can cease the injections and can activate one or more ozone removal devices to remove the ozone from the sealable volume to a safe level.
