Definitions

  • the invention relates to a dishwasher with steam generator and a method for its operation.
  • the cleaning process normally goes through four phases.
  • a pre-rinse phase the dishes are usually wetted without the addition of detergent.
  • detergent is added to the water.
  • a final rinse phase the dishes are prepared for spotless drying by rinsing with clean, hot water, with the rinse aid added to the water. Then follows a drying phase in which the heated dishes are dried.
  • US-A-4457323 discloses a dishwasher according to the preamble of claim 1 and a method according to the preamble of claim 6.
  • the object is to provide a dishwasher with better cleaning effect and good energy efficiency.
  • a steam generator is provided, with which the dishes can be acted upon in the rinse phase of steam.
  • the water condensing directly on the dishes has virtually no impurities, so that it dries without residue.
  • the condensation process makes it possible to supply the dishes with energy for the subsequent drying in an energetically efficient manner.
  • the water is heated in the bottom of the dishwasher and / or in the conduit system between the sump and the spray of the dishwasher for steam generation.
  • a corresponding heater can also be used to heat the water during the remaining cleaning phases.
  • the pump of the dishwasher is operated in at least part of the rinse phase with reduced flow rate at which the water exiting from the spraying water does not act on the dishes, but flows directly through the tub to the sump.
  • the water surface and thus the heat transfer and the steam discharge are increased.
  • overheating of the steam generator is prevented.
  • rinse aid can be applied to the dishes, which promotes drying without visible residues.
  • FIG. 1 This figure shows a schematic section through a possible embodiment of the dishwasher.
  • the dishwasher has a housing 1, in which a tub 2 is arranged for receiving the dishes to be cleaned.
  • a front door 3 can be opened.
  • two harness bodies 4a, 4b are provided, which define a dish receiving area.
  • a lower spray arm 5 is provided between the two baskets 4a, 4b, an upper spray arm 6, and above the upper dish rack, an auxiliary nozzle 7.
  • the two Spray arms 5, 6 and the auxiliary nozzle 7 form the spraying means, with which water can be introduced into the tub 2.
  • a sump 8 is provided at the bottom of the tub 2. From this, the water passes via a first line section 9 to a pump 10, from which it is conveyed via further line sections 11, 12 back to the spraying means. Further, the dishwasher still has suitable means for supplying fresh water and for discharging dirty water (not shown).
  • a heater 13 This forms the steam generator discussed below and can also be used to heat the water in the pre-rinse phase and the main rinse phase.
  • the heater 13 may, at least partially, also be arranged in the sump 8 and / or on the pump 10.
  • the processes in the dishwasher are controlled by a symbolically illustrated controller 14, which can be operated in a known manner by the user.
  • a water level detection e.g. In the form of a conductivity, pressure or turbidity measurement, it is possible to monitor the level in the sump and, if necessary, trigger the supply of fresh water.
  • the heater 13 and / or the pump 10 can be controlled clocked.
  • a temperature sensor is preferably provided in the water in the region of the heater 13, the signal of which is monitored by the controller 14.
  • an active locking of the door can be done, with which the door can be locked during at least part of the rinse phase to protect the user when exiting the door from escaping hot steam.
  • the door 3 may be provided with a suitable locking.
  • the user can be made aware of the vapor with suitable means of indication.
  • Pure steam may be able to attack certain dishes (knife blades, glass).
  • at least one corrosion inhibitor can be added to the water. It is also conceivable to provide a sacrificial anode in electrical or electrolytic contact with the dishes, e.g. in the area of the cutlery basket.
  • the steaming of the dishes described here can either be integrated in the process flow with each program or programs that are particularly suitable for it (eg glass program), or actively selected and deselected by the user via the control panel of the device (via a button or in the adjustment mode).
