摘要:
A box-type dishwasher has a treatment chamber or a conveyor- type dishwasher has at least one treatment zone. A wash system of the treatment chamber or the treatment zonehas a wash tank for wash liquid, a plurality of spray nozzles, in at least one wash tube, for spraying wash liquid onto the washware, and a wash pump, connected to the at least one wash tube by a line system, for supplying wash liquid from the wash tank to the spray nozzles. The at least one wash tube has a central cleaning opening which is formed in such a way that at least some of the wash liquid which is supplied to the wash tube by the wash pump flows back into the wash tank via the central cleaning opening in a cleaning mode of the dishwasher when the central cleaning opening is opend for flow.
摘要:
The present invention includes a washing tub, a washing unit, a washing pump, a heating unit, a temperature detection unit, and a control unit. In the washing, the control unit performs: spraying the washing water by the washing unit while the washing water is heated by the heating unit, at a start time; when the temperature of the washing water reaches a first predetermined temperature, stopping the heating of the washing water for only a predetermined time and spraying the washing water. Thereafter, the control unit controls to perform spraying the washing water by the washing unit while the washing water is heated by the heating unit again, until the temperature of the washing water reaches a second predetermined temperature. This can achieve a dishwasher capable of sufficiently removing dirt dried and stuck on eating utensils and dirt stuck on cooking utensils during cooking.

Verfahren zum Beaufschlagen von innerhalb eines Spülraumes (18) einer Geschirrspülmaschine (1) angeordneten Sprüheinrichtungen (20a, 20b, 20c) mit Spülflotte, wobei die Spülflotte wahlweise in eine erste oder mehrere zu je mindestens einer Sprüheinrichtung führende Leitungen geleitet wird, wobei während einer ersten Heizphase Spülflotte in die erste, zu mindestens einer ersten Sprüheinrichtung (20a) führende Leitung geleitet und mittels eines Verflüssigers (12) eines Wärmepumpenkreislaufes (9), der an der ersten Leitung angeordnet ist, erwärmt wird, wobei während einer zweiten Heizphase Spülflotte in mindestens eine zweite zu mindestens einer anderen Sprüheinrichtung (20b, 20c) führende Leitung geleitet wird, während in der ersten Leitung Spülflotte steht, und wobei während einer weiteren ersten Heizphase Spülflotte wiederum in die erste, zu der ersten Sprüheinrichtung (20a) führende Leitung geleitet wird, wobei der Verflüssiger (12) über die drei Heizphasen hinweg kontinuierlich betrieben wird. Ebenfalls ist eine Geschirrspülmaschine (1) mit einer Wasserweiche (19c) offenbart, um Spülflotte wahlweise zu einer ersten und / oder mindestens zweite Leitung zu leiten, wobei an der ersten Leitung ein Verflüssiger (12) eines Wärmepumpenkreislaufes (9) angeordnet ist.
摘要:
Apparatus for recovering the washing and/or rinsing liquid in a dishwashing machine comprising a tub (2) in which the dishes are washed and/or rinsed, at least one discharge pump (11), with associated motor (12), for discharging the washing and/or rinsing liquid from the tub and the machine on completion of an operating cycle, together with an auxiliary tank (10) for recovering at least some of the liquid used in a machine operating cycle for subsequent use thereof. The apparatus comprises a first line (25, 29) connecting the outlet (14) of said discharge pump (11) with said auxiliary tank (10), filter means (26, 27, 28) inserted in said first line (25, 29), a second line (30) connecting said auxiliary tank (10) with the interior of the tub (2), together with flow diverter means (16, 17, 18) located downstream of said discharge pump (11) which are capable of sending the flow of liquid entirely towards said auxiliary tank (10) or entirely towards the drain (21).
摘要:
The present invention relates to a method and device for detecting detergent present in process water in a household appliance for washing and rinsing goods. To this end, turbidity of the process water is measured (S101), which measured turbidity signal indicates the presence of detergent in the process water. Subsequently noise level of the measured turbidity signal is determined (S102), which noise level indicates type of detergent present in the process water. Field tests have shown that detection of the particular type of detergent used in a household appliance for washing and rinsing goods, i.e. whether distinction can be made between liquid/gel or tablet/powder detergent disposed in water for washing the goods, is difficult by means of analyzing the measured level of turbidity, which typically is measured by a turbidity sensor. Advantageously, by measuring the turbidity of the water and subsequently analysing the measured turbidity signal to determine noise levels in the measured turbidity signal output from the turbidity sensor, it is possible to distinguish between liquid/gel detergent on the one hand and tablet/powder detergent on the other.
摘要:
A dishwashing machine comprises a wash tub (3), an electric pump (87) for supplying water from a bottom (3a, 88) of the tub (3) to a sprinkler system (83-86), a switchable device (40), operatively set downstream of a delivery section of the electric pump (87), for controlling supply of water to the sprinkler system (83-86), a water-storage system (30, 45, 46, 50) comprising a tank (30) and a control system including control means for issuing a command for start-up of at least one program for treatment of the dishes that includes at least one step of charging water from the water mains to the tub (3), at least one step of treatment of the dishes, and at least one the step of filling of the tank (30). The switchable device (40) comprises a casing (41), mounted displaceable within which is a distributor member, which can be actuated by an actuator for assuming a plurality of operating positions, amongst which at least one position of opening a first outlet (44), for supplying a first sprinkler (83), and of simultaneously closing another outlet (43), for supplying a second sprinkler (84). The casing (41) of the switchable device (40) has a third outlet (45) that is always open; i.e., it is open irrespective of the operating position assumed by the distributor member. The third outlet (45) is connected via a third pipe (46) to a first opening (39a) of the tank (30) that functions alternatively as inlet and as outlet for the water with respect to the cavity of the tank. Between the third outlet (45) and the first opening (39a) of the tank (30) valve means (50) operate, which can be controlled independently of the switchable device (40).
摘要:
A dishwasher comprises a wash tank with a collecting sump (3) at the bottom and a decalcifier (1) whose outlet (1a) is connected to the collecting sump (3), between the outlet (1a) of the decalcifier (1) and the collecting sump (3) there being arranged a valve (7) suitable to divert the decalcified water to a duct (8) ending with a nozzle (9) that projects into the wash tank. In this way, the user has available in a simple and inexpensive way a source of decalcified water that can be used for ironing, cooking, washing laundry and the like.
