Definitions

  • the invention relates to a dishwasher according to the preamble of patent claim 1.
  • a known dishwashing machine of this type on the market has an ion exchanger, in the fresh water supply line of which a free flow path is arranged behind a water inlet valve controlled by the program control unit of the machine and which, according to DE-C 3 239 226, is assigned a storage tank which can be filled with fresh water and is summarized in a one-piece unit.
  • the storage container has a number of chambers connected in a liquid-conducting manner, one chamber of which is connected to an outlet line to the salt storage chamber.
  • the salt storage chamber is connected to the ion exchanger by a brine line with a shut-off valve.
  • the salt storage chamber is arranged next to the ion exchanger in the machine below the storage container, so that when the shut-off valve is opened via the program switch, the salt storage chamber is fed exclusively with stored water under the effect of gravity from the storage container.
  • a water hardness switch (DE-A 3 302 566 or GB-A 2 133 975) is assigned to the multi-chamber storage tank, with the free flow path, the storage tank a condensation shaft is integrated into a one-piece unit.
  • the dishwasher is also equipped with a level control device (DE-GM 8 218 877), which has a level control vessel connected to the washing container or its drain pan through an overflow partition and comprises one or more overflow chambers which can be emptied by suction lifters and which by means of sensors when certain filling levels are reached stops the water inlet by closing the water inlet valve and / or a safety valve (DE-PS 3 114 644).
  • a level control device DE-GM 8 218 877
  • the dishwasher is also equipped with a level control device (DE-GM 8 218 877), which has a level control vessel connected to the washing container or its drain pan through an overflow partition and comprises one or more overflow chambers which can be emptied by suction lifters and which by means of sensors when certain filling levels are reached stops the water inlet by closing the water inlet valve and / or a safety valve (DE-PS 3 114 644).
  • the invention has for its object to design a dishwasher of the type mentioned so that the effort for manufacture and assembly is reduced and the machine against leaks in the liquid guides is safer.
  • the dishwasher designed in accordance with the invention has the advantage that the container unit made of plastic is arranged next to the washing container and the bottom drain pan, which has a fresh water connection with a free flow path, a channel connection to an ion exchange chamber receiving ion exchange mass, a storage container for dispensing selectable water volumes, and a drain line from the storage container has a salt storage chamber and a brine line to the ion exchanger and is connected via an outlet of the ion exchange chamber to the rinsing container or its drain pan.
  • the level control vessel which responds to normal and safety levels and / or an overflow level of the rinsing tank, is integrated into the plastic unit and is connected to the drain pan of the rinsing tank via the connection of the tank unit in the manner of a communicating tube.
  • a control element 10 is provided in the distribution chamber 9 and forms a water hardness switch. Depending on the hardness of the fresh water at the installation site of the dishwasher, the control element is brought into a certain position. This makes it possible to measure the amount of brine to be supplied to the ion exchanger to regenerate its filling from the salt storage chamber by supplying the salt storage chamber from the storage container with only the water supply from one chamber or the water supply from several chambers.
  • the container unit 1 is connected to the fresh water supply line of the dishwasher via a fresh water connecting piece 11 behind a water inlet and / or safety valve (not shown). From the fresh water connection piece 11, a fresh water channel 12 of the container unit 1 leads to a free flow path 13 which is also integrated into the container unit. Behind the free flow path 13, a continuation 14 of the fresh water channel leads to the ion exchanger 2. An outlet 15 of the ion exchange chamber 2 is connected to the washing container or connected to its drain pan.
  • a level control vessel 16 In addition to the ion exchanger 2 accommodated in the bottom of the container unit 1, there is also a level control vessel 16.
  • the level control vessel 16 is via a bottom opening 17 and the outlet 15 as a communicating tube with the Ab trough or the rinsing container connected.
  • a first overflow partition 18 in the level control vessel lies with its overflow edge at the level of the normal filling level 19 of the washing container. If this water level in the rinsing tank is reached, a small amount of water spilling over the overflow partition 18 into a first chamber 20 is sufficient to raise a float 21 provided therein that it actuates a switch 22 to close the water inlet valve. If the rinsing tank is emptied by switching on the emptying pump, the water level in the level control vessel falls simultaneously with the water level in the rinsing tank, a siphon 23 starts and empties the chamber 20.
  • a second overflow partition 26 is provided in the level control vessel 16 in front of a second chamber 25 forming an air trap chamber up to the level of the safety level.
  • a pressure switch (not shown) or a pressure cell of a safety valve is connected to the air trap chamber via a line connection 27.
  • a second siphon 28 is used to empty the second chamber.
  • the salt storage chamber Opposite the outlet of the brine line 7 from the salt storage chamber 5, the salt storage chamber has a bottom sieve 29 and a side wall sieve 30. In addition to the side wall screen 30, a tube 31 or the like which is connected to the flow with the salt storage chamber and in which a float 32 is provided for indicating the lack of salt is provided.
  • an overflow channel 33 branches off to the ion exchanger 2. If the salt storage chamber is filled with salt, the displaced, excess brine passes through the overflow channel 33 into the ion exchanger and it is prevented that the brine is not used and undesirably overflows into the rinsing container. 34 with a channel for ventilation of the brine line 7 is designated.
  • the container unit 1 comprises a condensation chamber 35 with guide webs 36 arranged therein.
  • the condensation chamber 35 is connected to the flushing container via a compensating opening 37. Vapors emerging from the rinsing container are precipitated in the condensation chamber 35.
  • the container unit has a ventilation opening 38 above the condensation chamber, to which there is an air channel to the free flow path 13 and to the condensation chamber 35.
  • a valve 40 which can be controlled by the program switch of the dishwasher is arranged in a valve housing 41 of the container unit.
  • the storage container 8 can be filled by leakage water from the free flow path 13. If the storage tank is overfilled, the excess water is passed through the condensation chamber 35 and the compensation opening 37 into the rinsing tank.
