Definitions

  • the invention relates to a method for operating a water-conducting domestic appliance, in particular for a dishwasher or a washer-dryer.
  • a water-conducting household appliance ie a dishwasher known.
  • a drying system a sorption device with reversibly dehydratable material is provided, which extracts a quantity of water in a drying step of the air to be dried and stores them.
  • a regeneration process or a desorption is then carried out, in which an air stream flowing through the desiccant is heated by means of an air heater. With the heated air flow, the amount of water stored in the desiccant is released as hot steam and returned to the washing and heated to be cleaned items.
  • this type of heating is time consuming.
  • an additional heating such.
  • a water heater can be provided, which is operated simultaneously for air heating.
  • the invention is based on a method for operating a water-conducting domestic appliance, in particular for a dishwasher or a washer dryer, which comprises a plurality of successive partial program steps, of which in at least one partial program step at least temporarily heats a first medium with a first heating element and treated by loading the heated first medium is heated.
  • a second medium is heated with a second heating element and the material to be treated is heated with the heated second medium.
  • a higher performance of the second heating element allows to accelerate the heating process. It also ensures that the power consumption below a maximum power consumption of the water-conducting household appliance remains.
  • the maximum power consumption is limited by the maximum power capacity of the home-side supply network that serves the power supply of the water-bearing household appliance with electrical energy.
  • a power consumption of the water-conducting household appliance exceeding the maximum power capacity of the home-side supply network leads to an overload of the home-side supply network with the result that fuse elements, such as fuses or circuit breakers, trigger and a further energy supply is prevented. This ensures uninterrupted operation of the water-conducting household appliance.
  • a first partial program step at least temporarily only a first medium is heated with the first heating element and in a second partial program step at least temporarily with only the second heating element.
  • the first medium is a gaseous medium and the second medium is a liquid medium.
  • the higher heat capacity of the liquid medium reduces the heating time.
  • the heating of the gaseous medium can be carried out by an electric air heater, for example. Supported by a fan blower for circulating the gaseous medium.
  • the heating of the liquid medium can be done by a water heater, for example. Supported by circulating pump for circulation of the liquid medium.
  • treated material is subsequently subjected to a second medium.
  • This may be a pre-rinse step involving e.g. In the case of a dishwasher coarse soils are removed from the treatment or ware, or to a cleaning step with detergent addition to remove stubborn dirt.
  • At least one exchange of a medium takes place between two partial program steps. It sets a mixing temperature, which is between the temperature of the liquid medium and the temperature of the item to be treated after the first part program step.
  • the temperature difference to be overcome between the mixing temperature and the maximum temperature to be reached in the purification step is correspondingly lower, so that correspondingly less energy has to be expended.
  • a cleaning agent is added in a part program step designed as a cleaning step for the purpose of cleaning articles to be treated.
  • a partial program step designed as a pre-rinsing step for cleaning articles to be treated is carried out without addition of detergent, so that the pre-rinse step is carried out immediately before the cleaning step in which higher temperatures are achieved than in the pre-rinse step.
  • a post-wash phase is carried out during the cleaning step, while the material to be treated is heated by being acted upon by second medium heated by the second heating element.
  • a partial program step is formed as a rinsing step with heating of rinsing liquor, in which expansion agents are added.
  • a partial program step designed as an intermediate rinsing step for cleaning treated items is carried out without addition of detergent, so that the intermediate rinsing step is carried out immediately before the rinsing step in which higher temperatures are achieved than in the intermediate rinsing step.
  • the last partial program step a drying step is performed, is absorbed in the second medium of a reversibly dehydratable material.
  • liquid stored in the reversible dehydrogenatable material is available again for a new treatment cycle.
  • the reversibly dehydratable material is at least partially desorbed, so that subsequently the reversibly dehydratable material is receptive again.
  • a dishwasher with a washing container 1, in which not shown, to be cleaned dishes in dish racks 3, 5 can be arranged.
  • two spraying arms 7, 9 provided in different spraying levels are arranged by way of example as spraying devices, via which the washware to be cleaned is supplied with washing liquid.
  • a pump pot 11 is provided with a circulating pump 13, which is connected via feed lines 14, 15 fluidly connected to the spray arms 7, 9.
  • the sump 11 is also connected via connecting pieces with a fresh water supply line 16 coupled to the water supply network and with a discharge line 17 in which a sump pump 18 for pumping out the rinsing liquid from the rinsing container is arranged.
  • the rinsing container 1 has in its upper region an outlet opening 19, which is connected via a line 21 with a drying device designed as sorption device 22.
  • a drying device designed as sorption device 22 In line 21 to the sorption 22 an air blower 27 and a heating element 24 are connected.
  • the sorption device 22 contains as drying agent a reversibly dehydratable material, such as zeolite, with which in a drying step T air is dried.
  • zeolite reversibly dehydratable material
  • the zeolite provided in the sorption device 22 absorbs the moisture of the air and the comparatively dry air is returned to the washing container 1 again.
  • the amount of water m 2 stored in the zeolite in the drying step T can be released again in a regeneration process, ie during desorption, by heating the desiccant of the sorption device 22.
  • a heated by the heating element 24 to very high temperatures air flow through the sorption 22, with which the stored water in the zeolite is released as hot water vapor and recycled back into the washing compartment 1.
  • Fig. 2 is a temporal program sequence with the individual partial program steps of a rinse, namely pre-rinse V, cleaning R, intermediate rinse Z, rinse K and drying T, shown.
  • the above-described regeneration process in the sorption device 22 can be found in the in the Fig. 2 shown temperature-time profile in the time interval .DELTA.t R instead.
  • the in the Fig. 2 indicated partial program steps are controlled by a control device 25 by appropriate control of the circulation pump 13, the drain pump 18, the air blower 27, the drying device 22 and other control components.
  • the regeneration process ⁇ t R starts according to Fig. 2 and 3 at the beginning of the cleaning step R at time t 0 .
  • .DELTA.t R stored in the drying agent amount of water m 2 is returned as water vapor in the washing compartment 1. This amount of water m 2 was removed in the drying step T of the previous rinse during an adsorption ⁇ t A to be dried, laden with moisture airflow.
  • the provided in total in the cleaning step washing liquid R m is thus obtained from a supplied via the fresh water line 16 of fresh water and 1 m of the recirculated in the regenerating process .DELTA.t water quantity R m 2.
  • heating is first carried out during the regeneration process ⁇ t R by means of the second heating element 24, ie the air heating with which the one heating power Q 2 is introduced into the washing compartment 1. Subsequently, a heating power Q 1 is introduced into the washing container 1 with the first heating element 23, ie the water heater.
  • the heating power Q 1 of the water heater 23 may be about 2,200 W, while the heating power Q 2 of the air heater 24 is only in the order of 1,400 W.
  • the controller 25 is in signal communication with a changeover switch 26 which is manually operable by the user. Upon actuation of the switch 26 can user side of the above based on the Fig. 2 described first, energy-saving rinse mode to a second rinse mode described below are switched.
  • the heating of the rinsing liquid quantity in the cleaning step R takes place in a, compared to the first rinse mode time-reduced heating phase .DELTA.t H1 as shown in the Fig. 3 is shown.
  • the heating phase ⁇ t H of both the first purge mode (in dashed line) and the second purge mode (solid line) is shown.
  • the regeneration process .DELTA.t R is brought forward in time. Ie. the regeneration process .DELTA.t R starts here already during the Vorpül suitses V and temporally superimposed on the start time t 0 of the cleaning step R.
  • the cleaning temperature T R is reached accelerated in the second rinse mode, whereby accordingly, the cleaning step R 1 can already be terminated at a preferred time t E1 .
  • the start of the water heater 23 - alternatively to the embodiment shown - even with the start time t 0 of the cleaning step R 1 done. Namely, at the beginning of the heating phase, the water heater 23 initially heats only the rinsing liquid in the rinsing container 1 and only with a time delay the air. It therefore exists at the beginning of the heating phase ⁇ t H1 no risk that an excessively heated air flow during the regeneration process .DELTA.t R reach the sorption 22 and can damage the zeolite thermally.
  • Fig. 4 is a described during the second rinse mode rinsing method according to the second embodiment described.
  • the regeneration process ⁇ t R takes place completely outside the heating phase ⁇ t H.
  • the regeneration process .DELTA.t R .DELTA.t R2 is from one another in time-separated segments regeneration .DELTA.t R1, divided, by way of example in the Fig. 4 are about the same size in time.
  • the first regeneration segment .DELTA.t R1 is already in Vor Cyprus Colour V.
  • the second regeneration segment .DELTA.t R2 then starts after the heating phase .DELTA.t H during the Nachwaschzeit N.
