Definitions
- the present invention relates to a dishwashing machine.
- It also relates to a washing process used in such a dishwashing machine.
- the present invention relates generally to the field of dishwashing machines for domestic use, and in particular a dishwashing machine comprising at least one dishware basket on which is disposed a facade for channeling the flow of the dishwashing machine. washing water between at least one dish rack facade and the counter door. This flow of wash water is intended to clean the storm door.
- the storm door provides a surface to recover all the dirt when loading the dishes into at least one basket of dishes. Therefore, the storm door must be cleaned at each wash cycle.
- This cleaning device consists of using the washing water spraying means arranged in the tank.
- said washing water spraying means consist of reels and nozzles.
- a first reel is mounted on the bottom wall of the vessel, a second is connected to a crockery basket, and a nozzle is attached to the top wall of the vessel.
- wash water jets must be tangential to the storm door to minimize the impact sound of said wash water jets on the surface of the storm door.
- a dishwasher comprising a water supply device therein.
- Said water supply device comprising a water inlet tube extending in a position above the upper wall of the tank. An opening of the tube passes through the upper wall of tank.
- a siphon receiving water from the tube is supported by the inner surface of the door.
- the inlet of the siphon is in spaced relationship with the outlet opening of the tube but in flow relationship when the door is closed.
- the outlet opening of the siphon discharges the water inside the tank.
- the intermediate portion of the siphon is made to provide a water trap to prevent the passage of detergent or dirty washing liquid near the tube.
- the dishwashing machine described in the document US 2,655,024 A has the disadvantage of filling a siphon to pour water from said siphon without benefiting from a particular pressure. Therefore, the water discharged on the storm door does not remove the soils of said storm door.
