A dishwasher comprising a tub, a reuse tank, and a controller for implementing a wash cycle in the tub, the controller comprising a clock, the controller operably coupled to a recirculation pump and a drain pump, the controller configured (a) to cause the recirculation pump to supply liquid used during the wash cycle to the reuse tank, (b) to monitor via a clock a period of time that the liquid is within the reuse tank, and (c) when the period of time is greater than a predetermined period of time, (i) to cause a control valve in an outlet conduit to open and allow the liquid to flow from the reuse tank to a sump and (ii) to cause a drain pump to drain the liquid from the sump and out of the dishwasher.

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.

The present disclosure relates to a dishmachine that includes at least two tanks and methods of using the tanks to isolate, substantially isolate, or incrementally isolate different chemistries from each other during a cycle. The disclosed dishmachine design and method allows for the use of two different, and potentially incompatible, reactive, or offsetting chemistries to be used in the same dishmachine cycle.

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.

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.

The present invention relates to a dishwasher and a manufacturing method thereof. The dishwasher according to an embodiment of the present invention includes a water guide extending upward from a sump and supplying washing water to an upper nozzle and a top nozzle, and the upper pipe and the top pipe are separately provided to the water guide, so pressure of the washing water applied to the upper pipe and the top pipe can be reduced.

The present invention relates to a dishwasher for washing fruits and vegetables with less water and minimum energy use. The dishwasher (M) comprises main body; first basket (S); bottom area (1) in which there are provided two-way valve (1a), first channel (1b) and second channel (1c); washing compartment (2) comprising third channel (2a), first water outlet (2b), second water outlet (2c) and drainage connection unit (2d); fruit and vegetable washing apparatus (F) located on the first basket (S) and comprising chamber (4) in which fruits and vegetables are washed, carrying member (2) providing connection to the first basket (S) and one side of which is connected with lower side of the chamber (4), first water inlet (7) through which water reaching the first water outlet (2b) is transmitted into the carrying member (2), second water inlet (8) transmitting water from the second water outlet (2c) into the chamber (4); and control unit which controls operation of the valve (1a) such that water is transmitted to the second channel (1c) for washing fruits and vegetables or to the first channel (1b) for washing dishes inside the dishwasher (M), in response to the user-selected washing program of the dishwasher (M).

A method for handling a clogging condition in a dishwasher may include detecting the clogging condition; upon detecting the clogging condition, interrupting a wash cycle of the dishwasher and executing a remedial operation to remove the clogging condition. The remedial operation may include executing a drain operation for a predetermined drain time during which a drain pump may be continuously or intermittently operated to drain water from a sump of the dishwasher; following the drain operation, executing a fill operation for a predetermined fill time during which a fill valve may be continuously or intermittently activated to add water to the dishwasher; and following the fill operation, executing a circulation operation during which a circulation pump may be continuously or intermittently operated to remove the clogging condition. A dishwasher and a control system for handling a clogging condition are also provided.

According to one embodiment of the present disclosure, a dishwashing machine includes a tub accommodating tableware, a nozzle assembly spraying washing water, a vane assembly changing a traveling direction of the washing water sprayed from the nozzle assembly to move linearly inside the tub, a user interface for receiving a divided washing zone selected by a user, and a control unit controlling movement of the vane assembly to wash the selected divided zone by the washing water including the changed traveling direction.
