A dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.

A washing appliance configured to heat water supplied to the washing appliance by utilizing heated process water drained from a compartment of the washing appliance arranged to accommodate goods to be cleaned. The washing appliance comprises a tank configured to contain the water being supplied to the compartment of the washing appliance, a valve configured to be in fluid communication with said tank to control a flow of the water contained in the tank being supplied to the compartment of the washing appliance, a fresh water conduit extending inside the tank, the fresh water conduit being configured to transport the water supplied to the washing appliance, a drain water conduit configured to transport the drained heated process water, the drain water conduit being arranged to extend inside, and coaxially with, the fresh water conduit inside the tank.

The present inventive concept relates to a method for optimizing water usage in a device utilizing water for a group of cleaning procedures, wherein the device comprises a sensor arrangement (518) and a data processing device, wherein the method comprises the steps of: determining a first substance content (400a) of first cleaning phase water from a first cleaning phase of the cleaning procedure (428) using the sensor arrangement (518); in the data processing device, receiving data comprising a target substance content interval requirement (844) of at least one of a plurality of cleaning phases (314); in the data processing device, comparing the first substance content to the target substance content interval requirement (844); and forming cleaning phase water to be used in the at least one of the plurality of cleaning phases (314) by transferring the first cleaning phase water to the at least one of the plurality of cleaning phases (314) based on the comparison.

The present disclosure relates to a dish washer having a heat pump, and the dish washer may include a washing tank provided with a sump at a bottom surface thereof and provided with an accommodation space for storing dishes therein; a heat pump system provided with an evaporator, a compressor that compresses and circulates refrigerant, a condenser that heats washing water for washing the dishes, and an expansion apparatus; and a heat exchange system that exchanges heat between water for heat transfer to the refrigerant and the evaporator, thereby enhancing the heat exchange performance and efficiency of the evaporator.

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.

Ergonomic Intelligent Dishwasher comprising of closed-loop carousel system, tableware storage holder and a Wash-Pod. Individual tableware is inserted through an opening where the tableware attaches to a closed-loop, speed-adjustable carousel-system that moves the individual tableware, in a queue-fashion, through one or more wash cycle as the attached-tableware travels towards the tableware separation-mechanism. Tableware separation-mechanism is activated or deactivated for each individual tableware in the said queue on the carousel based on user-define setting or an internal quality-control process, thus, when deactivated, attached tableware on the carousel continues to travel through additional said cleaning cycle in the loop until such time when carousel-tableware separation-mechanism is activated. Once the tableware is discharged and separated from the carousel, the tableware is directed to one or more tableware storage holder. As part of the same unit, Wash-Pod is a housing within the unit with closeable lid for washing kitchenware items based on user parameters.

A dish washing machine including a housing having an interior wash space for washing dishes. The housing has a liquid inlet for adding a liquid to the dish washing machine. At least one spray nozzle sprays the liquid onto dishes positioned within the interior wash space. The machine further includes a heating tank for heating the liquid which is supplied to the at least one spray nozzle for spraying onto the dishes in the interior wash space. At least one heat exchange system is within the housing. The at least one heat exchange system transfers heat from the liquid heated by the heating tank to the liquid added to the dish washing machine from the liquid inlet.

A household dishwasher includes a receiving area for receiving an item to be washed, and a tank assembly receiving dishwashing fluid. The tank assembly includes a first tank section with an inlet, via which the tank assembly can be supplied with dishwashing fluid, and a second tank section with an outlet, via which dishwashing fluid in the tank assembly is able to exit the tank assembly. The first and second tank sections are fluidically connected together and arranged fluidically in series such that dishwashing fluid in the first tank section is displaced into the second tank section when additional dishwashing fluid is introduced into the first tank section via the inlet.

At least one spray nozzle sprays the liquid onto dishes positioned within the interior wash space. The machine further includes a heating tank for heating the liquid which is supplied to the at least one spray nozzle for spraying onto the dishes in the interior wash space. At least one heat exchange system is within the housing. The at least one heat exchange system transfers heat from the liquid heated by the heating tank to the liquid added to the dish washing machine from the liquid inlet.

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 heat pump having a compressor, an evaporator, an expansion apparatus, and a condenser provided on an inner bottom surface of the tub to exchange heat with washing water inside the tub; and a controller that controls the heat pump to be driven to increase the temperature of the washing water inside the tub. As a result, the heating time of washing water may be shortened.
