Problems solved by technology

The disadvantage here, however, is that when the motor is switched on and off in regular and / or rapid succession, the time between switching operations may not be sufficient to cool the resistor and thus again assume a state with a high resistance value
In addition, such additional resistors are usually susceptible to vibration (as they often have ceramic housings) and may have a shortened service life due to dynamic loading
In addition, additional resistors cause costs and require construction space

Embodiment Construction

[0039] In the following drawings, the same reference numerals are used for the same technical features of different embodiments.

[0040] figure 1 A domestic appliance 1 is shown, which has a first functional unit 10 for providing a user with a first appliance function, wherein the first functional unit 10 is active. Household appliances 1 can be used in particular by e.g. Figure 4 The method 100 is run as shown in the schematic diagram of the method steps. The domestic appliance 1 also has a motorized second functional unit 20 for providing the user with a second appliance function. The first functional unit 10 can also be driven via a drive 11 having an electric motor 12 and an interface 13 for supplying the electric motor 12 . A preconnection circuit 30 is also connected between the interface 13 and the motor 12 , and the preconnection circuit 30 has a current limiting element 31 for limiting the current 200 . In addition, the driving device 11 has a motor control dev...

Abstract

The invention relates to a household appliance (1) having a movable first functional unit (10) for providing a first appliance function for a user, an electrically powered second functional unit (20)for providing a second appliance function for the user, and a drive device (11) for driving the first functional unit (10), a drive device comprises an electric motor (12), an interface (13) for supplying power to the electric motor (12), and a pre-connection circuit (30) arranged between the interface (13) and the electric motor (12), the pre-connection circuit (30) having a current-limiting element (31) for limiting a current (200).The invention also relates to a method (100) for operating a household appliance (1).

Description

technical field [0001] The invention relates to a domestic appliance and a method of operating a domestic appliance according to the preambles of the independent device claims. Background technique [0002] Electric domestic appliances are known from the prior art. Electric motors are often used here, via which, for example, rotatable or translationally movable parts of the domestic appliance are moved in order to carry out certain functions of the domestic appliance. Thus, for example, cooking machines are known in which a knife is driven in rotation by an electric motor for chopping or mixing ingredients. In order to combine as many functions as possible in a single appliance, such cooking machines usually have other functions. Especially when the electric motor is switched on, high currents can occur which can damage the electric motor and / or other electrical components. [0003] In order to limit such inrush currents and / or inrush currents, it is also known to connect...
