Problems solved by technology

In order to increase the area where the alkali is trapped, the system has deflected walls, they slightly increase the coverage, but there is still a large part of the bottom of the pot that is not covered, where the alkali accumulates and ultimately fails to fulfill its purpose

Embodiment Construction

[0025] figure 1 A kettle 10 of a household appliance (not fully shown in the figure) is shown, cut through its wall 14 to show the interior. Inside it is possible to see the heating element 20, which is curved for greater contact with the water to be heated.

[0026] Be provided with breach 16 on kettle top wall 14, it plays the effect of kettle water pouring inlet 18 simultaneously. This gap can be closed by a hermetically closed plug 30 , which absorbs the pressure generated inside the jug by steam during operation of the heating element 20 .

[0027] Also provided on the top wall 14 of the kettle 10 is a discharge duct 32 for discharging steam from the kettle to an iron (not shown). This connection is normally regulated via an electronic steam dosing valve.

[0028] Inside the jug there is a device 40 for removing hydroalkali precipitated from the heated water, consisting of three spherical compact units made of stainless steel wire wound on itself and connected to each ...

Abstract

The invention relates to an electrical household appliance, comprising a boiler, in which water is brought to a boil and which on one wall has a passage that can be closed by a plug and which has a device for removing lime scale that has formed inside of the boiler, wherein said device can be pulled out through the passage of the boiler wall. The device for removing lime scale is designed as at least one compact unit, which has a pore structure to which the lime scale adheres and which can be pulled out of the boiler for cleaning purposes.

Description

technical field [0001] The invention relates to a household appliance comprising a jug into which water to be heated is filled. The jug has a gap in the wall and can be closed by a plug. The jug also has a device for removing caustic water formed in the jug and this device can be removed through a notch in the wall of the jug. Background technique [0002] In household appliances, they have a jug in which water is heated, and alkali water or carbonate is formed on the walls of the jug in the form of a layer and in the form of deposits. If the amount of deposits and base layer is significant, foam is produced by the action of steam bubbles and may flow from the kettle. Alkali in the case of an iron may clog the control solenoid valve, or settle on the clothes, thereby leaving undesirable marks. [0003] The water alkali that accumulates in the kettle must be periodically removed, thereby avoiding these drawbacks. It is generally recommended, for example, in irons, to clea...
