Abstract:
The invention relates to a dishwasher (1), especially a domestic dishwasher (1), the liquid system (100) of which has a cleaning solution reservoir (30) for making available cleaning solution (S) for the cleaning cycle (SG) of a subsequent dishwashing program. In order to fill the cleaning solution reservoir (30) with cleaning solution, hot water (WH) can be obtained from an external hot water supply (WH) via a hot water inlet (13, 14) and can be introduced into the liquid system (100).
Abstract:
The invention relates to a method for operating a water-carrying household appliance, especially a dishwasher or a tumble dryer, comprising a plurality of successive partial program steps, a first medium being heated at least temporarily by a first heating element (24) in at least one partial program step, and the product to be treated then being heated by being subjected to the heated first medium. According to the invention, when the first heating element (24) is inactive, a second medium is at least temporarily heated by a second heating element (23) and the product to be treated is heated by the heated second medium.
Abstract:
In the case of a dishwasher, in particular a domestic dishwasher (1), having a control device (2) for implementing a dishwashing cycle (SG) for the cleaning of washware, having a dishwashing chamber (7) for accommodating the washware during the dishwashing cycle (SG), having an inflow valve (18) which can be operated by the control device (2) and is intended for introducing dishwashing liquid (S) into the dishwashing chamber (7), and having a circulating pump (22), which can be adjusted, in particular controlled or regulated, by the control device (2) and is intended for circulating the dishwashing liquid (S) located in the dishwashing chamber (7), the dishwashing cycle (SG) comprises at least one filling sequence (F, F1, F2, F3), in the case of which the inflow valve (18) is open during a primary filling phase (PF), the duration of which is dependent on a time setting (DT) which corresponds to a desired quantity (FMS) of dishwashing liquid (S) which is to be introduced into the dishwashing chamber (7) and is sufficient for concentricity of the circulating pump (22) running at a nominal speed (NN), and in the case of which use is made of a concentricity-monitoring unit (25), at the end of the primary filling phase (PF), to carry out a concentricity check (RP) to ascertain whether the circulating pump (22) running at the nominal speed (NN) is operating concentrically, wherein the filling sequence (F1) is terminated if the circulating pump (22) is operating concentrically, and the filling sequence (F2, F3) is continued if the circulating pump (22) is not operating concentrically.
Abstract:
The invention relates to a rinsing method for a water-bearing domestic appliance, especially for a dishwasher, which especially comprises a drying unit (22) containing a drying agent that can be reversibly dehydrated, rinsing liquid being heated to a first temperature (TR1) in at least one cycle step (R) of a first rinse cycle in a first operating mode (I). The rinsing method comprises the following steps: detection of scale formation in the water-bearing domestic appliance; comparison with a nominal value for scale formation; and carrying out a rinse cycle in a second operating mode (II) while the rinse liquid is heated to a second temperature (TR2) which is higher than the first temperature (TR1), when the nominal value is exceeded.
Abstract:
The aim of the invention is to create a household dishwasher (1) with a washing tub (2) having at least two spray devices (5, 6) which act on material to be washed by means of a liquid which is delivered by a circulation pump (7), whereby said material is arranged in the washing tub. The dishwasher also comprises a reversing device (20) for supplying the spray devices (5, 6). The reversing device (20) is arranged at a non-restrictive location. To achieve the aim of the invention, the delivered liquid of the circulation pump (7) is fed to a feeding pipe (11) of a flow heater (10) and through said flow heater (10) which is provided with at least two outflow pipes (12, 13) for feeding the liquid to different spray devices (5, 6). Said spray devices (5, 6) can be opened or closed by means of a reversing device (20) which is arranged at the flow heater (10) in the direction of flow in front of the outflow pipes (12, 13) in such a way that one of the outflow pipes (12, 13) or a number of outflow pipes (12, 13) or all outflow pipes (12, 13) are opened or closed alternately, one after the other and/or permanently.
Abstract:
The invention relates to a method for operating a dishwasher (GS), in particular, a domestic dishwasher, wherein at least washing material in an inner chamber (IR) is at least temporarily treated with heated fluid, wherein in order to heat the fluid air is first passed through a drying material (ZEO) suitable for exothermic drying and then the air together with the heated fluid driven out of the drying material (ZEO) is led through an outlet opening (AU), through which the air with fluid driven out of the drying material (ZEO) enters into the inner chamber (IR). According to the invention, the outlet opening (AU) is cooled.
Abstract:
The invention relates to a drying device of a dishwasher (GS), comprising at least one sorption container (SB) containing reversibly dehydratable sorption material (ZEO). Said sorption container is connected to the rinsing container (SPB) of the dishwasher by means of at least one air guiding channel (LK). The sorption material (ZEO) is provided in the sorption container (SB) as bulk in the form of a granular solid or granulate having a plurality of particle bodies with a granular size of essentially between 1 and 6 mm, in particular between 2.4 and 4.8 mm. The filling height (H) of the particle body corresponds to at least 5 times the particle size.
