Problems solved by technology

Thus on the one hand the number of circuits in the household appliance must be limited; on the other hand corresponding circuits whose energy consumption in standby mode is very small must be selected and used
This in turn is associated with a relatively large outlay in selecting the circuit and with increased costs of the circuit
In addition, the main power supply unit 4 also consumes a relatively large amount of energy in standby mode

Embodiment Construction

[0034] exist figure 2 The circuit arrangement 20 shown in FIG. 2 is used for operating a domestic appliance, for example a domestic appliance for preparing food, for example an oven and / or a hob. A household appliance may thus generally be a cooking appliance. Here, the domestic device can be switched back and forth between a standby mode (stand-by) and an operating mode (active mode). What is sought is to reduce the energy consumption of the domestic appliance in standby mode, that is to say the energy consumption of the circuit arrangement 20 , to a minimum.

[0035] The circuit arrangement 20 comprises a network connection 21 at which a network voltage UN is applied relative to a reference potential (ground) when the circuit arrangement 20 is connected to a network. The circuit arrangement 20 also includes a plurality of circuit units 22 a , 22 b to 22 n , the number of which can in principle be arbitrary. These circuit units 22 a , 22 b to 22 n may be side-by-side circ...

Abstract

The invention relates to a domestic appliance that can be switched between a stand-by mode and an operational mode, comprising a mains connection (21), to which an electrical mains voltage (UN) can be applied, a main supply unit (23), which is designed to provide an operating voltage (UB) from the mains voltage (UN) at the output (32) of the main supply unit, and an electrical load (29a to 29f), which is supplied with the operating voltage (UB). In the stand-by mode, at least the output (32) is disconnected from the mains connection (21) by means of an electrical switch (25). Voltage supply means (41) coupled to the mains connection (21) tap the mains voltage (UN) in the stand-by mode and produce a supply voltage (UV) from the mains voltage (UN), by means of which supply voltage the switch (25) is closed and thus the domestic appliance is switched from the stand-by mode to the operational mode. The invention further relates to a method for operating a domestic appliance.

Description

technical field [0001] The invention relates to a domestic appliance, in particular for food preparation, which can be switched back and forth between a standby mode (Standby, standby) and an operating mode (Aktivmodus, active mode). The domestic appliance has a grid connection to which a grid voltage can be applied relative to a reference potential. The domestic appliance also contains a mains supply unit, for example a power supply part, which supplies the electrical operating voltage from the mains voltage, ie at the output. The operating voltage is supplied to electrical consumers such as main control units and / or sensors of domestic appliances. The invention also relates to a method for operating such a household appliance. Background technique [0002] The use of power supply parts (Netzteil) in household equipment is known technology. This power supply part has the task of converting the mains voltage, which is an alternating voltage, into an operating voltage that...
