A household appliance includes a treating chamber and a liquid sump. A liquid circuit fluidly couples the liquid sump and the treating chamber. An immersible laminate heater is located within the liquid sump. The immersible laminate heater includes a pair of electrodes and a structure including at least a first layer and a second layer.

A dishwasher and method utilize one or more sprayers to generate steam within a wash tub of a dishwasher by directing one or more sprays of fluid onto a heating element disposed in the wash tub of the dishwasher.

A method for removing moisture from moist air in an appliance, such as a treating chamber of a dishwasher, wherein a drying system includes a condensing system and heat exchange systems that enhance condensation with both ambient air and cold water. The method includes storing cold water for use during a cycle of operation; recirculating the moist air in the treating chamber through a condenser; during the recirculating, flowing ambient air over the condenser; and during the recirculating and after the flowing ambient air, flowing the cold water over the condenser.

Provided is a structure of a sump assembly of a dishwasher. The dishwasher includes a tub forming a washing chamber, and a sump assembly provided at a lower side of the washing chamber and configured to store washing water in the washing chamber, wherein the sump assembly includes a sump housing having a water storage chamber storing the washing water and a sidewall portion forming the water storage chamber, and a heater provided on the sidewall portion to apply heat to the washing water stored in the sump assembly. The heater includes a planar heating element, and the planar heating element provided in a cylindrical shape forms the sidewall portion.

The present disclosure relates to a dishmachine that includes at least two tanks and methods of using the tanks to isolate, substantially isolate, or incrementally isolate different chemistries from each other during a cycle. The disclosed dishmachine design and method allows for the use of two different, and potentially incompatible, reactive, or offsetting chemistries to be used in the same dishmachine cycle.

The dishwasher includes a cabinet provided with a washing space inside thereof, and a nozzle unit for spraying washing water into the washing space. The nozzle unit includes a first unit body and a second unit body. Any one of the first and second unit bodies includes a first coupling rib formed along at least a portion of the periphery and a second coupling rib spaced apart from the first coupling rib by a predetermined distance. The other of the first and second unit bodies includes a third coupling rib inserted between the first and second coupling ribs and a second coupling rib located inside the third coupling rib, and stepped ribs configured to face each other.

A dish washer and a control method are disclosed. The dish washer includes a sump and at least one nozzle configured to inject water. The dish washer also includes a distributor configured to receive water of the sump and distribute the water to the at least one nozzle. The dish washer also includes a reservoir configured to receive and store the water of the sump. The dish washer also includes a circulation path configured to connect the sump and the distributor. The dish washer also includes an inflow path configured to branch off from the circulation path to supply the water of the sump to the reservoir. The dish washer also includes a first valve configured to open or close the inflow path and a second valve configured to open or close the outflow path, and the outflow path is configured to flow the water out of the reservoir.

A dishwasher includes a case, a sump connected to an inside of the case and collecting washing water, a washing pump receiving washing water from the sump and generating steam, and a steam nozzle connected to the washing pump and spraying steam to the inside of the case. The steam nozzle includes a steam nozzle body having a steam inlet and including a steam accommodating portion accommodating steam therein, a first steam sprayer provided in the steam nozzle body and spraying steam to the inside of the case, and a second steam sprayer provided in the steam nozzle body and disposed at a position farther from the steam inlet than the first steam sprayer, wherein a tunnel flow path penetrating through a lower end of the first steam sprayer is formed to allow steam passing through the tunnel flow path to be introduced into the second steam sprayer.

Embodiments seek to disclose a drinking straw washing apparatus that includes a casing. A reservoir is positioned proximate to the casing and configured to comprise a cleaning solution. Cavities are serially positioned in the casing. A primary conduit is positioned proximate to the casing and operationally coupled to the reservoir. A plurality of drawers are each slidably and demountably positioned within a cavity. Applicators are positioned within each of the cavities and operationally coupled to the primary conduit. A secondary conduit is positioned in each drawer and operationally coupled to each of the nipples. Nipples are positioned within each of the drawers, each nipple is operationally coupled to the secondary conduit and configured to engage a straw end. A primary control circuit is positioned proximate to the casing. The drawers are hot swappable. The secondary conduit is coupled to the primary conduit when the drawer is positioned within the cavity.

A method and circuit for controlling or starting a U-shape single phase synchronous permanent magnetic motor (U-SPSPM motor) having a rotor and a stator and coupled to a single phase alternating current (AC) power source through a switch, including estimating back electromotive force (back-EMF) of the motor based on an observer model with inputs indicative of the measured signals, and triggering the switch to supply power to the motor based on the estimates of the back-EMF.
