A dishwasher includes a tub that defines a wash space configured to accommodate one or more objects to be washed, a base that is disposed below the, a door configured to open and close the wash space, a sump disposed under the tub and configured to store wash water, and an air supply device disposed at the base and configured to supply air to the tub, wherein the door is disposed forward relative to the sump in a front-rear direction of the base, and wherein the air supply device is disposed rearward relative to the sump in the front-rear direction.

Disclosed herein is a dishwasher including a main body provided with an open hole and a washing tub; a door configured to open or close the open hole; a door opening/closing member configured to open or close the open hole; an air curtain disposed in the main body, to operate a fan such that ambient air is sucked and the sucked air is discharged; a detector configured to detect information of the fan; and a controller configured to diagnose the failure of the fan based on the detected information of the fan, to control an operation of the door opening/closing member such that the door is opened at a predetermined open time and an open time of the door is delayed when the fan is a failure state, and to control an operation of the fan when the fan is a normal state during a drying operation.

A household dishwasher includes a dishwasher cavity for processing items to be washed, and an air outlet designed to blow out dishwasher interior air of the dishwasher cavity. The air outlet is arranged in a lower quarter of a height of the household dishwasher and extends as a slot outlet over at least half of a width of the household dishwasher.

A dish washer includes: a tub configured to receive an object to be washed and providing a washing space having an opening at a front side of the tub, a door configured to rotate relative to the tub between (i) a closing position that closes the opening of the washing space and (ii) a full opening position that exposes an entirety of the opening of the washing space, a door position sensor configured to sense a position of the door, a dry air supply configured to selectively generate a high-temperature dry air or a low-temperature dry air and supply the high-temperature dry air or the low-temperature dry air into the tub, and a controller configured to determine, based on the position of the door sensed by the door position sensor, whether to supply the high-temperature dry air or the low-temperature dry air.

A method controls a dishwasher including a tub configured to receive objects to be washed, a drying device configured to receive wet air from the tub and to discharge the wet air to an outside of the dishwasher, and a dry air supplier including a heating part and being configured to supply heated air to the tub. The method includes preheating the drying device by introducing dry air from the outside to the drying device before a first preset time from a start point of a drying operation, performing the drying operation at the start point, wherein the wet air is discharged from the tub during the drying operation, and cooling the dry air supplier by stopping operation of the heating part before a second preset time from an end time point of the drying operation.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. The beverage container washing system may include multiple concentric housing members supported on a base, and an air knife chamber that supply air from a stationary air supply to an air knife opening on a rotatable one of the concentric housing members.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A warewash machine carries out at least one of (i) delivering both compressed air and rinse liquid to a plurality of wash spray nozzles of the warewash machine for spraying onto the wares during at least part of a washing operation of a ware cleaning cycle, wherein the wash liquid is recirculated from a wash tank below the spray zone; or (ii) lowering wares from the spray zone into a wash tank below the spray zone to submerge the wares within wash liquid of the wash tank and delivering compressed air into the wash tank during at least part of a washing operation of a ware cleaning cycle; or (iii) delivering both compressed air and rinse liquid to a plurality of rinse spray nozzles of the warewash machine for spraying onto the wares during at least part of a rinsing operation of a ware cleaning cycle.

A method of controlling a dishwasher includes washing an object accommodated inside a tub by spraying water and detergent onto the object, rinsing the object by spraying water onto the object, drying the object by removing moisture adhered to the object, detecting an amount of a rinsing agent, comparing the detected amount of the rinsing agent to a predetermined amount, based on the comparison, determining whether the detected amount of the rinsing agent is less than the predetermined amount, and increasing at least one of a temperature of water to be supplied in the rinsing or a drying time in the drying based on determining that the detected amount of the rinsing agent is less than the predetermined amount.

A dishwasher has a liquid supply system with a first conduit portion through which the liquid passes, and an air supply system with a second conduit portion through which the air passes. The first conduit portion at least partially forms the second conduit portion to define a thermal transfer interface. A heating system includes a heating element provided on the thermal transfer interface. Activation of the heating element provides heat to both the liquid supply system and the air supply system.
