Definitions

  • the invention relates generally to the field of commercial dishwashing.
  • the invention relates to dishwashers, in particular commercial dishwashers that are designed as programmable machines.
  • Programmable machines are dishwashers that can be loaded and unloaded manually.
  • the programmed machines also known as "box-type warewashers” or “batch dishwashers"
  • the programmed machines can be pass-through dishwashers, also called hood-type warewashers, or front loader warewashers.
  • Front loaders can be undercounter machines, top counter machines or free-standing front loaders.
  • a dishwasher designed as a programmed machine usually has a washing system with a washing pump, a pipe system connected to the washing pump and a large number of spray nozzles formed in at least one washing arm.
  • the washing liquid in the washing tank can be conveyed by the washing pump via the pipe system to the washing nozzles and sprayed onto the items to be cleaned by the washing nozzles in the treatment chamber. The sprayed washing liquid then flows back into the washing tank.
  • Such a dishwasher designed as a programmer is known, for example, from the publication DE 10 2005 023 429 A1 known.
  • a commercial dishwasher designed as a programmed machine differs from a domestic dishwasher in particular in that a commercial dishwasher must be designed in such a way that - depending on the selected cleaning programme - programme running times of between one and five minutes can be achieved, whereas domestic dishwashers usually have running times of up to 2.5 hours or more. Due to the short programme duration required for commercial dishwashers, the techniques used in domestic dishwashers cannot usually be easily transferred to commercial dishwashers.
  • a commercial dishwasher designed as a programmer is usually equipped with two independent liquid systems that are completely separate from each other.
  • One liquid system is a wash water circuit, which is responsible for washing the items to be washed, with the washing being carried out using recirculated water from the dishwasher's wash tank.
  • the other liquid system is a fresh water system, which is responsible for the final rinse.
  • the final rinse is carried out using fresh water, preferably fresh water from a water heater.
  • the fresh water is also collected in the dishwasher's wash tank after spraying.
  • the main purpose of the rinse is to remove any lye that is on the items to be washed.
  • the water that is added to the wash tank during the rinse step flowing rinse water to regenerate the wash water in the wash tank.
  • an amount of wash liquid equal to the amount of fresh water is pumped out of the wash tank.
  • front-door machines Commercial dishwashers that are designed as automatic programmers and for batch loading and unloading of the treatment chamber with items to be washed are particularly front-door machines or basket-passing machines.
  • front-door machines the items to be washed are placed in a basket and the basket loaded with items is placed through a front door into the treatment chamber of the dishwasher and removed again through the front door after cleaning.
  • basket-passing machines the dish baskets loaded with items to be washed are manually pushed into the treatment chamber from an inlet side and manually removed from the treatment chamber from an outlet side after the end of a washing programme.
  • Front-door machines and basket-passing machines contain only a single treatment chamber for treating the items to be washed.
  • the front-door machines can be under-counter machines or over-counter machines.
  • Two drying processes are mainly used in commercial dishwashers that are designed as programmable machines.
  • the dishes are removed from the machine while they are still hot after the final rinse process, where they are then dried in the ambient air for four to ten minutes.
  • the dishes are usually left in the baskets in which they were placed for cleaning in the dishwasher to dry.
  • the second method which can be used for commercial front-door or under-counter dishwashers
  • air drying takes place within the treatment chamber of the dishwasher.
  • Fresh air drying systems are used here.
  • Such fresh drying systems for commercial front-door or under-counter dishwashers always work with a high air volume flow in the range of 25 to 100 m 3 per hour in order to be able to dry the dishes remaining in the treatment chamber in a very short time.
  • the high air volume flows are due to the short drying process in the commercial sector.
  • the active drying time of a commercial dishwasher is many times shorter. While the program run time for drying in a domestic dishwasher is around 30 minutes to 2.5 hours, the program run time for drying in commercial use is between 1.5 and 5 minutes.
  • the solution according to the invention is characterized in particular in that the dishwasher has a drying module which is arranged on the horizontal wall and/or ceiling area of the dishwasher and is designed in such a way that it is completely accommodated in the free space laterally delimited by the side walls and the front of the hood when the hood is in the open position.
  • the drying module guarantees a high drying efficiency, since the drying module circulates air within the closed treatment chamber of the hood dishwasher and thus a very high circulation rate/air volume flow can be achieved without causing high losses in the installation room.
  • process step (iii) and process step (iv) the drying module is activated, preferably for up to 15 seconds, in order to expose the cleaned items to air during a so-called dripping phase between the washing phase and the rinsing phase.
  • the housing of the drying module is divided into a first area, in which the fresh air inlet of the drying module and an air inlet of the drying module, and into a second area in which the drying air outlet of the drying module is provided.
  • the suction side of the suction fan is in fluid connection with the first area and the pressure side of the suction fan is in fluid connection with the second area.
  • the exemplary embodiment of the dishwasher 1 according to the invention shown in the drawings is designed as a hood-type dishwasher, which can be loaded and unloaded via a hood 2 with a washing basket.
  • the hood 2 can be pushed upwards in a vertical direction using a handle.
  • Such hood dishwashers are designed to clean large quantities of dishes in the shortest possible time.
  • washing and rinsing systems usually consist of a washing arm and a rinsing arm.
  • a commercial dishwasher 1 of the type considered here usually has an upper and a lower washing and rinsing system.
  • an effective flow cross-section of the second air outlet 16 is preferably variably adjustable, also with the aid of a corresponding ventilation slide.
