An appliance having: a control unit managing the operation of the appliance; at least one hydraulic component actionable for distributing water/treating liquids within the appliance; a plurality of sensors arranged for acquiring information regarding physical parameters associated with the operation of the appliance, and a module managing at least part of the water/treating liquids distribution within the appliance. The module includes the at least one hydraulic component; at least two sensors of the plurality of sensors, and a local control unit managing the operation of the at least one hydraulic component and/or receiving the information acquired by the at least two sensors.

A method of controlling a dishwashing appliance may include determining that a cooking operation has been input to the dishwashing appliance via a mobile device, receiving an input option for the cooking operation via the mobile device, and activating the pump to supply a predetermined volume of fluid to the container at a predetermined temperature.

A dishwasher has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214″) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

Dishwashing appliances and methods, as provided herein, may include features or steps such as performing a drain cycle; detecting a pressure (P1) during an activation period of the drain cycle; comparing the pressure to a first predetermined pressure limit; comparing the pressure to a second predetermined pressure limit; determining a target fill value based on a difference between a normal fill volume and a fluid volume corresponding to P1; and initiating a fill cycle based on the target fill value.

An appliance and method for operating an appliance is provided. The appliance includes a pump configured to flow a volume of fluid, a flow nozzle configured to eject the fluid provided from the pump, and a motor configured to selectively operate the pump to flow the fluid through the flow nozzle. The method includes acquiring a dataset including a function of current magnitude and time corresponding to operation of a pump to flow a volume of fluid; determining an average current magnitude based at least on the dataset; determining a standard deviation based at least on the average current magnitude; comparing the standard deviation to a threshold to determine whether to transmit a control command based.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

The present disclosure relates to a drainage device and a dishwasher having the same. The drainage device includes a drain pump including a drain port for discharging water, a drain pipe guiding discharge of water discharged from the drain pump, an air chamber in which the drain pump is connected to an upper portion thereof and the drain pipe is connected to a lower portion thereof, and an air pump configured to inject air into the air chamber, thereby more surely blocking the backflow of water to the drain pump by air injected into the air chamber through the air pump.

Proposed is ultrasonic spoon washing apparatus and method, which use ultrasonic waves generated by one or more ultrasonic oscillators provided on a vertical side wall of polygonal surfaces of a wash tub, so that spoons contained in a spoon support part rotating forward/in reverse may very efficiently and conveniently be washed while the number of revolutions changes for each washing stage, the apparatus including: a frame body; the wash tub mounted inside the frame body; one or more ultrasonic oscillators provided on an outer side of the vertical side wall; a forward/reverse rotation support part including a support shaft and a rotation support pipe; a spoon support part including a holder and a spoon accommodation container; a rinsing water supply part configured to spray the rinsing water together with a rinsing aid; and a wastewater and foreign material discharge part configured to discharge, to the outside, wastewater and foreign materials.

The present disclosure relates to a dishwasher having a heat pump, including a dishwasher body provided with a tub configured with a washing space therein and a sump provided at a bottom of the tub to temporarily accommodate washing water; a washing water storage unit provided in the dishwasher body to store washing water therein; a heat pump having a compressor, an evaporator, an expansion apparatus, and a condenser provided to exchange heat with the washing water of the washing water storage unit; and a controller that controls the heat pump to increase the temperature of the washing water of the washing water storage unit. As a result, a heating time of washing water may be shortened, thereby suppressing a time required for washing dishes from being prolonged.

Dishwashing appliances and methods, as provided herein, may include features or steps such as, in a standalone sump and filter flush mode, measuring a water level in the sump of the dishwashing appliance. The sump and filter flush mode also includes comparing the measured water level in the sump to a preset value and draining water from the sump when the measured water level in the sump is greater than the preset value.
