Definitions

  • the invention relates to a dishwashing machine with an addition device arranged inside the door with a first chamber closable by means of a first lid for receiving block-shaped cleaning agents.
  • Published patent application DE 3623027 A1 discloses a dishwasher with an addition device arranged on the inside of the door.
  • the adding device has two separate with a powder detergent or detergent filling bare chambers.
  • a programmable lid of the feeder covers both chambers.
  • the lid of the adding device has a plurality of openings over a chamber, which form a Austechnikgitter.
  • the openings of the lid are each smaller than the grain size of the powdered cleaning or rinsing agent.
  • the spray jets reaching the chamber via the rinsing grate dissolve the cleaner, so that virtually only dissolved detergent or small-particle cleaning or rinsing agent can pass through the openings.
  • the small-sized detergent dissolves after a short time in a treatment room arranged rinse water.
  • dishwashers are known from the prior art, in which an adding device is arranged on the inside of the door, which has a chamber to be closed with a lid for storing a powdery or block-shaped cleaning agent.
  • the cleaning agent is supplied to the chamber by a user and then the chamber is closed by the user liquid-tight with the lid. Only after a partial program step "prewash" is the lid by means of a Open control and control electronics, so that the detergent falls into the treatment room of the dishwasher.
  • a disadvantage of this solution is that the cleaning agent, in particular the block-shaped cleaning agent falls in a dry state in the treatment room. Since the block-shaped cleaning agent has not previously been moistened or has come into contact with water, residues of the block-shaped cleaning agent are still present in the treatment room and / or on a good to be cleaned at the end of the flushing process, which must be removed by the user. Thus, individual active ingredient components of the cleaning agent are not used, so that it comes to a negative rinsing result. The active ingredient components not dissolved during rinsing have a clouding effect on the material to be cleaned, in particular of glassy material.
  • the object of the invention is to supply the block-shaped cleaning agent to a treatment space of the dishwashing machine in dishwashers of the type described in more detail above in such a way that the active ingredient components dissolve at their most favorable time in order to improve the washing result.
  • the first cover has at least one opening which retains the block-shaped cleaning agent while allowing the introduction of liquid.
  • the block-shaped cleaning agent is already moistened during the pre-rinsing.
  • the liquid supply is designed through the opening such that the block-shaped cleaning agent is not dissolved and rinsed out, but merely moistened.
  • the block-shaped cleaning agent is supplied to a treatment space of the dishwasher after the pre-rinsing in a moistened or moistened state, so that the individual active ingredient components of the block-shaped cleaning agent can unfold at the most favorable time. This ensures that no residues of the block-shaped cleaning agent are arranged in the treatment space after operation in the treatment room of the dishwasher.
  • the openings of the first lid are circular. This solution has the advantage that the manufacturing effort is very low and the solution is inexpensive to perform.
  • the surface of the openings is formed on a front side of the first lid smaller than the smallest surface of the block-shaped cleaning agent.
  • this achieves that the block-shaped cleaning agent does not fall out of the first chamber.
  • an uncontrolled falling out of the block-shaped detergent is excluded from the first chamber, so that the active ingredient components of the detergent can unfold in a subsequent rinsing process at their most favorable times.
  • At least one second chamber is used for introducing a pulverulent and / or liquid and / or gaseous cleaning agent.
  • the main advantage here is that the user can choose between the block-shaped, the powdered, the liquid or the gaseous cleaning agent. This ensures flexibility by selecting the cleaning agent for the user.
  • the second chamber of the adding device can be closed in a fluid-tight manner with the first lid.
  • This arrangement ensures that the powdery and / or liquid and / or gaseous cleaning agent in the second chamber remains dry during the pre-rinsing. Furthermore, it is prevented that the cleaning agent or small amounts of cleaning agent are supplied during the pre-rinsing the treatment room of the dishwasher. Consequently, the active ingredient components of the cleaning agent can be used at their most favorable phase during the rinsing process.
  • the first chamber and the second chamber are liquid-tightly separated from each other.
  • This solution is characterized in particular by the fact that the cleaning agent in the first chamber and the cleaning agent in the second chamber do not mix.
  • the liquid flowing into the first chamber through the openings of the first cover does not penetrate into the second chamber, so that possibly powdered cleaning agent in the second chamber is already moistened during the pre-rinsing.

  • Figure 2 shows a second embodiment of a detail schematically shown inner door of a dishwasher, on the inside of an addition device has two chambers for storing a powdery and a block-shaped detergent, each of which can be closed with a lid, in the view from the front.
