4 leading to the boiler the water inlet 2 is initially completely filled with water the cold water being poured in gets in contact with the hot inner surfaces of the boiler and evaporates immediately this undesirably generated steam escapes through the water filling inlet pipe this situation is shown in fig1 a where the water being poured in meets the steam escaping the boiler since the amount and speed of the steam are considerable the situation shown in fig1 b happens the water in the inlet cup 2 is carried along or displaced and splashes out of the water inlet cup 2 this is an uncomfortable and unsafe situation for the user fig1 c and 1 d illustrate a faster and safer refilling fig1 c is a detailed cross sectional view of the filling end 16 of the water filling inlet pipe 14 of the steam generating apparatus 10 fig1 d the steam generating apparatus 10 comprises a boiler 12 for heating water the boiler is equipped with heating elements 22 being in a thermal contact with a heating plate 24 at the bottom of the boiler 12 further temperature switches 26 28 are provided the water filling inlet pipe 14 comprises besides the filling end 16 an elbow like bending portion 20 and a boiler inlet end 18 the boiler 12 is connected with an iron 30 via a steam hose 32 an electro valve 34 is provided for the steam hose 32 between the boiler 12 and the iron 30 the detail operation of the steam generation delivering the steam from the boiler 12 to the iron 30 and applying the steam is discussed in more detail relating to the embodiments to follow as depicted in fig1.
