Definitions
- the invention relates to a method for operating a domestic appliance, which is connected to the electrical power supply to a supply network, in which a warming in operation electronic component of the domestic appliance with a cooling air flow of a cooling device of the domestic appliance is cooled. Furthermore, the invention relates to a domestic appliance, which is connected to the electrical energy supply to a supply network. Domestic appliances such as cookers, ovens and the like are connected to an external electrical energy network for energy. Such home appliances have temperaturbeaufhauste components such as radiators or motors that need to be cooled in order to protect these components in operation against overheating and thus from damage. In particular, however, electronic modules of domestic appliances, which also heat up during operation due to the radiator heat must be cooled in order to avoid a malfunction or impairment.
- devices in the energy-reduced operating state the so-called stand-by state, continue to be constantly connected to the power grid, so that there is also energy consumption in this regard.
- An inventive method for operating a domestic appliance is designed to the effect that the domestic appliance for electrical energy supply is connected to a supply network and at least one warming in operation electronic component of the domestic appliance with a cooling air flow of a cooling device of the domestic appliance is cooled. After switching off a radiator of the household appliance, the cooling air flow is further generated by the cooling air device and cooled at least the electronic component. When the cooling device is switched off, the household appliance is then disconnected from the supply network.
- the energy consumption of the domestic appliance can be reduced because even if no more of the components is needed and the domestic appliance is no longer needed for itself, there is no more coupling to the power grid.
- cooling of the furniture surrounding the household appliance is also provided for built-in appliances.
- the network separation is performed electronically controlled.
- the invention relates to a domestic appliance, which is connected to the electrical power supply to a supply network, and has an operating-warming electronic component and a cooling device for generating a cooling air flow for cooling the electronic component.
- the household appliance further comprises a circuit arrangement which is designed to continue operating the cooling air device after switching off a radiator of the domestic appliance and to further generate a cooling air flow for cooling at least the electronic component and completely shut off the cooling appliance, the domestic appliance from the supply network separate.
- the domestic appliance is an electric cooker or an oven or a hob or the like, wherein in this context in particular home appliances for preparing food with at least one radiator and / or a motor and / or a circuit carrier and a cooling air blower are included.
- Fig. 2 is a diagram in which operating states are shown as a function of time.
- the circuit arrangement 1 thus shows a part of the domestic appliance, which is an oven or an electric cooker or a hob.
- the household appliance can be connected to a supply network for the supply of electrical energy.
- the poles L and N are shown in the figure.
- the circuit arrangement 1 comprises an on-pushbutton S1 and a holding relay K1. Furthermore, a temperature switch V1 or alternatively a switch-on edge detection device is provided.
- an electronic module or an electronic component L1 is present.
- the circuit arrangement 1 further comprises a power supply G1.
- FIG. 2 shows a simplified diagram in which operating states as a function of time t, for example of a radiator HK and a cooling air blower KL, are shown.
- the domestic appliance is put into operation and at least one heating element is heated to heat a cooking zone or a baking chamber, it is switched on at time t0 and brought to a specific operating state Z1.
- the radiator heats up thereby and to prevent overheating of the radiator or other components of the domestic appliance, the cooling air blower KL is turned on at time t1 and brought to the operating state Z2.
- the radiator If the radiator is no longer needed in the active state, it will be switched off at the time t2, which in addition further cooling of the electronic module L1 and possibly furniture, in which the oven is arranged as a built-in unit, is required and the cooling air blower KL continues is operated. Therefore, energy is still required and the domestic appliance remains connected to the electric power grid.
- the cooling air blower KL Controlled by a control device and the circuit arrangement 1, the cooling air blower KL is operated in the active state over a further predetermined time, which is dependent on the temperature profile of the component to be cooled. The temperature detection can doing this via sensors. If a sufficient cooling of the component is then achieved at time t3, then the cooling air blower KL is switched off at this time t3. Essentially, at the same time, the household appliance is then also completely disconnected from the electrical power supply network, so that even in stand-by mode, there is no longer energy consumption and, as it were, an OW consumption state is reached.
