Method for operating a shortened dishwashing cycle of a dishwasher, dishwasher configured for running the shortened dishwashing cycle and computer program product for operating a shortened dishwashing cycle of a dishwasher. The dishwasher (10) includes a tub (12) configured to hold dishware during a dishwashing cycle, at least one circulation pump (50, 250), at least one heating element (230), and a controller (40, 240) configured to operate the dishwasher. The controller (40, 240) is configured to operate the dishwasher (10) according to at least one of a normal dishwashing cycle or the shortened dishwashing cycle. The method includes providing a first amount of warm water to the tub (12). The first amount of warm water is greater than a standard amount of water provided to the tub (12) for the normal dishwashing cycle. The method further includes, while the first amount of warm water is being provided into the tub (12), pulsing the circulation pump (50, 250) based on a predetermined timing sequence and activating the heating element (230) to heat the water within the tub (12).

Systems and methods are described, which relate to internet-of-things (IoT) feedback systems, in which data received from a given IoT device may be analyzed by a controller and used as a basis for controlling another IoT device and/or sending an alert to a user. The controller may activate a dehumidifier upon detecting activation of a sump pump. The controller may monitor water level data and alert a user and/or request maintenance of the sump pump upon detecting the water level exceeds a threshold. The controller may monitor dishwasher data to detect suboptimal performance of a dishwasher, in response to which the controller may instruct valves of a manifold and water heater to close to isolate the dishwasher, and instruct a water softener to elevate salt levels of softened water during a self-cleaning cycle of the dishwasher.

Disclosed is a heating circulation type drying module of a dishwasher using a fan module and PTC heaters. The dishwasher includes a cabinet defining the external appearance, a tub provided in the cabinet, a door for opening or closing the tub, a flow-path unit for circulating air inside the tub through a suction port and an exhaust port, which communicate with the tub, a suction duct for communicating with the suction port, an exhaust duct for communicating with the suction duct and the exhaust port, at least two heaters provided inside the exhaust duct for heating the air, and a fan for supplying the air to the heaters. The dishwasher may achieve improved drying performance via adjustment in the temperature of air to be discharged, and may reduce power consumption via omission of a rinsing water heating course.

A method of controlling a dishwasher includes: driving a circulation fan disposed in a circulation duct that communicates with at least two portions of a tub; controlling a rotational speed to change the rotational speed of the circulation fan; and driving an exhaust fan to discharge the air in the tub to the outside.

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 includes a drying system that incorporates a mixing conduit that mixes air streams from an exhaust fan that draws humid air from a wash tub and a mixing fan that draws ambient air from the surrounding environment of the dishwasher to lower a dew point of the air that is exhausted by the dishwasher. In some instances, an additional inlet fan may be used to direct ambient air into the wash tub, and in some instances, the ambient air drawing into the mixing conduit by the mixing fan may be untreated.

A dishwasher includes a drying system that incorporates a mixing conduit that mixes air streams from an exhaust fan that draws humid air from a wash tub, an inlet fan that supplies ambient air to the wash tub, and a gate device that is movable within a range of positions to regulate fluid flow through at least one of first and second inlets of the mixing conduit. A controller may perform a multi-stage drying operation that, in a first stage, controls the gate device while the inlet fan is deactivated, and in a second stage, additionally controls the speed of the inlet fan while controlling the gate device.

An automatic dishwasher having a tub defining a treating chamber and a housing physically separate from the tub and defining a sump to receive liquid sprayed into the tub, the housing having an inlet fluidly connected to a liquid outlet of the tub and an outlet fluidly coupled to a sprayer located within the tub to define a recirculation path for the sprayed liquid.

An adjustment device, an air duct structure, an exhaust system, a dishwasher, and a method for controlling the dishwasher are provided. The adjustment device is applied in an exhaust system. The exhaust system has an exhaust channel with a second air inlet and a first air inlet. The adjustment device includes an adjustment mechanism and a controller. The adjustment mechanism is configured to, under control of the controller, respectively adjust a flow rate of a first gas entering the exhaust channel through the first air inlet and a flow rate of a second gas entering the exhaust channel through the second air inlet, to control a ratio of the first gas entering the exhaust channel to the second gas entering the exhaust channel. Humidity of the second gas is lower than humidity of the first gas.
