A dishwasher includes: a cabinet defining an external appearance of the dishwasher; a tub disposed in the cabinet to form a space where to wash dishes; a heat exchanger disposed between the tub and the cabinet to form a space in which external air flows; and a condensing module disposed between the heat exchanger and the cabinet and configured to exchange heat of air discharged from the tub with the external air flowing in the heat exchanger such that the heat-exchanged air flows into the tub.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having at least one wash zone with an associated spray system for spraying liquid onto wares passing therethrough, wherein a downstream drying zone includes a blower for blowing air onto wares passing therethrough. The blower includes an ambient intake operatively connected to an ambient air flow path, a machine intake operatively connected to an internal machine air flow path and an exhaust intake operatively connected to a machine exhaust air flow path.

A dishwasher utilizing one or more sprayer rings disposed proximate to one or more tines of a dishwasher rack, where the sprayer ring(s) are in fluid communication with a fluid supply that is configured to supply a fluid to the one or more sprayer rings to spray fluid onto utensils disposed within the wash tub.

A dishwasher, a door assembly for the dishwasher and a method of drying the dishware in the dishwasher are provided. The dishwasher may include a tub portion adapted to hold dishware. The dishwasher may also include a duct having an inlet proximate to the top of the tub portion. The duct may be configured to receive warm air and vaporized water from within the tub portion. The dishwasher may further include a single blower configured to direct the warm air and vaporized water into the duct during a drying cycle. The blower may be configured to operate in a cyclic manner. In various embodiments, the blower may be configured to operate in a reverse direction for at least a portion of the drying cycle.

A dishwasher capable of shortening drying time is disclosed. The present device comprises: a main body having a washing tub provided therein; a door rotatably coupled to the main body so as to open and close the washing tub; a blowing duct having a passage provided between the outside of the washing tub and the inside of the main body so as to provide a flow path through which the air flowing from the outside flows, and a discharge port provided at the passage so as to spray air to the outside; and a blowing means connected to the blowing duct so as to provide the external air into the blowing duct, and forcibly causing wet steam in the washing tub to flow to the front of the main body, wherein the passage has at least one variable section for changing the cross sectional area thereof.

A method and dishwasher utilize one or more tubular spray elements that are both rotatable about longitudinal axes thereof and discretely directable by one or more tubular spray element drives between a plurality of rotational positions about the longitudinal axes thereof. Thus, through the provision of discretely directable tubular spray elements, fluid such as wash fluid and/or pressurized air may be focused in a wash tub, in many cases providing more efficient resource usage in the dishwasher.

A method and dishwasher utilize one or more sprayers that are coupled to both a liquid supply and an air supply through a common hydraulic circuit such that both liquid and pressurized air can be supplied to the one or more sprayers.

This disclosure proposes a cleaning device for cleaning items to be cleaned. The cleaning device has at least one fluid device for applying at least one cleaning fluid to the items to be cleaned. The cleaning device has at least one electrical load. The cleaning device further has at least one electrical connection for supplying electrical energy to the cleaning device. The cleaning device further has at least one energy store. The cleaning device is designed to receive electrical energy via the electrical connection and to temporarily store said electrical energy in the energy store. The cleaning device is further designed to supply electrical energy from the energy store to the at least one electrical load.

A distribution cap is configured to couple to a nozzle of a dish washer and to guide air from the nozzle to be discharged in a discharge direction. The distribution cap includes a fitting pipe configured to couple to the nozzle, a first bypass pipe that is connected to the fitting pipe and extends in a direction different from the discharge direction, where the first bypass pipe is configured to be positioned above the nozzle based on the fitting pipe being coupled to the nozzle, and a second bypass pipe that extends from an end portion of the first bypass pipe in the discharge direction, where the second bypass pipe defines a discharge opening at an end portion thereof.

Provided is a pre-drying device for a dishwasher, said pre-drying device being placeable inside a housing of the dishwasher in addition to a cleaning device and a drying device. The pre-drying device of the embodiment includes at least one orientation device that allows a jet of air to be directed onto depressions in dishes in order to remove leftover rinsing liquid from the depressions in the dishes following the cleaning process.
