Abstract:
A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone(40). A refrigerant medium circuit (100) includes a first condenser (86) and a second condenser (88), the first condenser (86) located upstream of the second condenser (88) in the refrigerant circuit. The refrigerant medium circuit includes a first flow path through the first condenser (86) and a second flow path 8114) in bypass of the first condenser (86), and a valve (112) for selectively controlling whether at least some refrigerant medium flows along the first flow path or the second flow path.
Abstract:
A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone. A refrigerant medium circuit includes a first heat exchanger arranged to deliver refrigerant medium heat to a first fluid and a second heat exchanger arranged to provide a heat exchange relationship between the refrigerant medium and a second fluid, the first heat exchanger located upstream of the second heat exchanger in the refrigerant medium circuit. A bypass arrangement for causing at least some refrigerant medium to selectively bypass at least one of the first condenser or the second condenser based upon subcooled refrigerant medium condition.
Abstract:
Disclosed is a control method of a dishwasher (100) including a tub (2) for receiving objects to be washed, a plurality of spray arms (711, 713, 715) for spraying wash water to the objects, and a steam nozzle (42) for spraying steam to the objects, the control method including a main washing cycle of washing the objects, a rinsing cycle of rinsing the washed objects using wash water, and a drying cycle of drying the objects after the rinsing is completed, wherein the drying cycle includes spraying steam, received from a steam source, to the objects to increase a temperature of the objects (a steam spraying step) and resupplying water to the steam source in order to prevent the steam source from being heated after the steam spraying step (a cooling step).
Abstract:
Dosing method for dosing a chemical product, particularly a detergent, in a dishwasher, comprising the steps: detecting a first loading signal of a washing liquid in a washing tank of the dishwasher; dosing a first quantity of chemical product in said washing liquid to obtain a washing mixture; detecting a conductivity value of said washing mixture at a first loading condition of the dishwasher; storing a conductivity threshold value equal to said conductivity value of said washing mixture at a first loading condition; dosing of a further quantity of chemical product in said washing mixture at an operation condition of the dishwasher in such a way to adjust a further conductivity value of said washing mixture detected in said operating condition until reaching said conductivity threshold value.

Eine Geschirrspülmaschine (1), insbesondere Haushaltsgeschirrspülmaschine, mit einem Spülbehälter (2) zur Reinigung von Geschirr, Gläsern, Bestecken oder ähnlichem Spülgut und mit einem phasenweise wasseraufnehmenden Mittel einer Sorptionstrocknungseinrichtung, insbesondere auf Basis von Zeolith, wobei während zumindest einer Desorptionsphase des wasseraufnehmenden Mittels erhitzte und wasserhaltige Luft über zumindest eine Ausblasöffnung (9) in den Spülbehälter (2) einleitbar ist, wird so ausgebildet, dassdie Ausblasöffnung (9) über eineeigens vorgesehene, insbesondereseparate,und auf diese gerichtete Kühlmittelbeaufschlagung kühlbar ist.
Abstract:
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.
Abstract:
A warewash machine includes in-situ tank soil load reduction that involves at least one of: (i) prior to addition of fresh water, draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path until wash liquid level in the collection tank drops below a standard operating level, and thereafter adding fresh water; or (ii) draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path while simultaneously adding fresh water; or (iii) adding fresh water such that wash liquid level in the collection tank rises above a standard operating level, and thereafter carrying out draining of the collection tank.
Abstract:
The invention relates to a method of automatic dishwashing in a dishwasher having a wash tank, comprising: in a first step, delivering a first composition to dishware in the tank in the form of a mist; and afterwards, in a second step, delivering a second composition to the dishware in the tank in the form of a jet; wherein the first and second compositions are different, the first composition comprises a bleach, and the second composition is alkaline and comprises a builder. The invention also provides a dishwasher adapted to carry out the inventive method.
Abstract:
A dishwasher (1) comprising a spray arm arrangement (2) and a washing chamber (3). The spray arm arrangement (2) comprises a spray arm (4) arranged to rotate around a first axis of rotation (5) within said washing chamber (3). The spray arm (4) is provided with one or more spray nozzles (6) arranged to spray washing liquid into said washing chamber (3). The dishwasher (1) further comprises a mechanical switch (7), for detecting an angular position of said spray arm (4). The spray arm arrangement (2) further comprises a activating device (8) arranged to rotate with said spray arm (4), which activating device (8) comprises at least one activating structure (9) arranged to cyclically activate said mechanical switch (7) during rotation of said spray arm (4).
Abstract:
The present invention relates to a dishwasher (1) comprising: a tub (2), an article rack (3), a water intake valve (4), a sump (5), a pump (6), a spray arm (7), a user interface (8) and a heater. The dishwasher (1) of the present invention comprises a low water safety circuit (9) having a pressure switch (10) and a control unit (11) having a plurality of washing programs, wherein each washing program has a plurality of subordinate washing programs which are respectively adapted to different loads. The control unit (11) allows the user to designate a washing program and subsequently detects the load on the basis of the total amount of water required in order to wet the dishes in the washing tub (2).
