    A steam iron (1) is described in which a pre-adjustable preset of the temperature is modified by a control depending on the existence of a steam request signal, the control (26) regulating a different theoretical temperature as the pre-adjustable preset of the temperature. With this, it can be ensured in a pre-selected range of low temperatures that, by increasing the temperature of the sole of the iron, it can be achieved to generate steam without forming small drops. The method according to the invention describes how steam generation is possible without the formation of droplets. (Machine-translation by Google Translate, not legally binding)

    when the switch for the immediate steam request 40 is activated, for example, in the control 26, the activation of the sole heating device 10 is caused directly, and through the temperature sensor 57 it is checked whether the sole 6 has a temperature Enough for steam generation. If this is the case, the pump 16 is activated, and water is introduced into the steam chamber 8 of the sole 6. In particular, through a preselection of the temperature set in the temperature regulator 50, the temperature can be predetermined. temperature setting, and control 26 can compare the predetermined temperature with the existence of a steam request signal. This steam request signal can be generated by the control 26 itself. In the event that a comparator device of the control 26 finds that there is a steam request signal and a certain temperature preselection, it can then be determined on a case-by-case basis. a sole 6 temperature is set that differs from the preselected temperature. In particular, in a range of low temperatures, for example, in an adjustable temperature range as a point in the temperature regulator 50, which is usually defined as being between 70 ° and 120 °, a higher temperature can be set for for example, a temperature of between 100 ° C and 180 ° C, preferably between 100 ° and 145 ° C, so that, also in a preselected range of low temperatures, steam can be generated safely without forming small droplets.
    Through the temperature sensor 57 and the temperature regulator 50, the control 26 can at any time verify what temperature the sole 6 has and what temperature is preselected. Depending on these two temperatures, the pump 16 can then be activated by the control 26 corresponding to a request for steam to evaporate the water, the pumping capacity being set by the control 26 so that during evaporation it is not possible form small drops. The temperature that can be preselected in the temperature regulator 50 is generally designed for dry fabrics. As soon as the water is evaporated, the temperature of the sole drops and should be brought back to the theoretical temperature, where the pumping capacity would have to be directed at the same time so that, depending on a decreasing temperature, The pump 16 carries an amount of water adapted to prevent droplets from forming during steam generation.
    As Figure 2 shows by means of a graph 200, there is a correlation between the pumping capacity of a water pump 16, indicated here with the reference symbol 210, and the temperature 220. As an example, the settings from

    temperature 226, which corresponds to a point in the temperature regulator 50 of the plate 1, 230, which corresponds to two points in the regulator 50 of the plate 1, and 250, which corresponds to three points in the regulator 50 of the plate 1, lie on a straight line. With 225, 235, 245, and 265 a corresponding regulation range for the corresponding temperature range is predetermined. For one point, for example, temperature fluctuations between 70º and 120º are allowed, while for two points temperature fluctuations between 100º and 160º are allowed and, for three points, the temperature should be between 140º and 210 ° C. In the example shown in Figure 2, a predetermination of the user 277 is shown, which corresponds to a temperature and a pumping capacity. However, as soon as water is transported to the sole 6 through the pump 16, the temperature of the sole 6 will drop, which is symbolized by the arrow 273. The temperature can be measured through the temperature sensor 57 , and the control 26 re-regulates the pumping amount of the pump 16 to prevent droplets from forming during steam generation. The regulation range is indicated here, for example with the reference symbol 280. In general, it has been found that, the lower the temperature, the greater the danger of small droplets forming during steam generation and at the temperature decreasing.
    The steam generation can be initiated, for example, automatically by an ironing program, or manually activated by the user with an immediate steam selector switch. As an example, when the pump is activated to transport water to the steam chamber, the heating element is also switched on so that steam can be generated on the sole in the steam chamber without delay.
    As Figure 3 shows, steam generation in a preselected range of low temperatures can be improved in accordance with the invention. To do this, the pumping capacity 210 upwards and the temperature 220 to the right are plotted analogously to figure 2. Similarly, the preselected temperature settings 226, 240 and 250 similar to Figure 2 are represented. The same applies to the regulation range 225, 235, and 245, which are assigned to the corresponding settings. In this particular case, as long as the pre-selection of the temperature is at a point and in the event that there is a steam request, in the control 26 a predetermination of the temperature 230 is set, which is actually above of the limit value corresponding to a preselection of a point. By way of example, a predetermination of the temperature of this type can be between 120 ° C and 180 ° C, preferably between 120 ° and 145 ° C and, preferably, 130 ° C.
