Boiler for use in a steam generating device

Abstract

A boiler (1) for heating water to steam comprises a boiler housing (10) having a bottom wall (12), a top wall (13) and a circumferential wall (14) extending between these walls (12, 13). When the boiler (1) is mounted in a steam generating device for generating steam and supplying steam to an appliance such as a steam iron (20), the boiler (1) is given an inclined orientation. In a lower portion (13a) of the top wall (13) of the boiler housing (10), an inlet opening (15) for letting in water to a boiler space (11) which is enclosed by the boiler housing (10) is arranged. When water is supplied through the inlet opening (15), the water lands on a lower zone (14a) of the circumferential wall (14) and flows further in a downward direction, along the circumferential wall (14). As a result, the water is pre-heated when it reaches the water which is already present in the boiler space (11), and there is no danger of the steam production getting interrupted.

Description

technical field [0001] The invention relates to a boiler for heating water, comprising a boiler shell enclosing a boiler space, wherein a water inlet for letting water into the boiler space is arranged in the boiler shell. Background technique [0002] Such steam boilers are well known and used in a variety of personal appliances including steam ironing appliances, active ironing boards capable of supplying steam to the object to be ironed, facial saunas, steam cleaning appliances and coffee makers. [0003] In EP0821096 a steam generating device is disclosed which comprises a boiler, a water tank and a water supply pipe connecting the tank to the boiler, and which has a delivery pump embedded in it. The boiler has a sloping bottom on which a heating plate is mounted externally. In a specific embodiment, the heating plate and the bottom are tightly fitted by bolting, and a thermally conductive paste is applied between them. [0004] For the purpose of controlling the water...

AI Technical Summary

Problems solved by technology

[0007] The disadvantage of the steam generating device known from EP0821096 is that the water inlet hole needs to be placed in the region of the top area of ​​the bottom of the boiler, and thus the position of the hole cannot be chosen freely

For example, the holes cannot be positioned such as to provide a passage for water to flow into the lower area of ​​the bottom of the boiler, because in this case the lesser amount of heated water present in this lower area would immediately and freshly The supply of cold water mixes, which causes an interruption of steam production
