Problems solved by technology

[0004] However, this method of activating the fouling indicator has the disadvantage that, in its simplest implementation, it does not reflect well the true calcification state of the iron, and in its most complex implementation variant, it is relatively costly , in addition this variant of implementation cannot be used for steam irons comprising a simple drip device instead of a pump to feed the evaporation chamber

Embodiment Construction

[0020] by figure 1 The schematically shown iron includes a box 1 arranged above a base 2 equipped with a steam outlet not shown in the figure. The base 2 is thermally connected to a heating body 3 which includes an evaporation chamber 30 that is normally closed by a cover 4.

[0021] The heating body 3 includes a heating resistor 31, which is supplied by a temperature regulator 6 thermally connected to the heating body, and the temperature regulator 6 ensures that the temperature of the base 2 is around the set temperature determined by the user through the button 60 adjust. The iron is connected to the grid via a cable 5.

[0022] As known in the art, the box 1 contains a water reservoir 8 equipped with a filling hole 8a leading to the front surface of the iron, and includes a dripping device 9 equipped with a secondary reservoir 8. To the water passage of the evaporation chamber 30, the device usually has holes whose cross-section can be reduced by a punch.

Abstract

Steam iron comprising a scale indicator (10) and comprising a heating body (3) including a steam chamber (30) for producing steam, characterized in that it comprises means for calculating the electrical energy used by the iron and means which activate said scale indicator (10) when the calculated energy exceeds a predetermined threshold value.

Description

Technical field [0001] The present invention relates to a steam iron including a heating body equipped with an evaporation chamber, and in particular, the present invention relates to a steam iron including a fouling indicator that can remind the user of the necessity of maintenance operations. Background technique [0002] It is known in the patent application document EP1 045 932 that a steam iron is equipped with an evaporation chamber supplied by a pump, in which a fouling indicator is activated after a predetermined time of use of the iron is reached, and the iron includes the ability to measure the cumulative use of the steam iron Time device. In an optimized implementation variant, the fouling indicator is activated only after a predetermined operating time of the pump, so as to obtain better accuracy of the fouling state of the iron. [0003] The advantage of this indicator is that it can prompt the user to perform the automatic cleaning operation of the iron at regular in...
