- a typically spring-assisted damping mechanism for damping door movement can be accommodated in the hinge housing.
- the primary side is attached as far to the front as possible on the door hinge, in particular on a front end section of the hinge housing.
- the primary side can be brought particularly close to the secondary side and an air gap between the primary coil and secondary coil halves can be kept particularly small. Further advantages are that the temperature is comparatively low at this point and the unit is protected by a condensate drip channel, if available.
- the primary side protrudes laterally from the front end section and is connected via at least one on one longitudinal side of the hinge housing.
- running cable with a connector arranged on a rear end section, in particular on a rear end face, of the hinge housing is connected.

- the primary coil can protrude laterally perpendicularly from the stationary part, in particular the hinge housing.
- the at least one cable runs at least in sections within the hinge housing or in a cable duct arranged on the longitudinal side of the hinge housing.
- the course within the hinge housing is particularly space-saving, while the use of a cable duct on the outside enables particularly simple laying.
- a primary-side part of the energy transmission device is designed as a cohesive, in particular rigid module that includes the primary side (primary coil (s) and electronics), the cable duct and the connector.
- the advantage is thus achieved that the primary-side part can be handled in one piece and thus particularly simple assembly is made possible and, moreover, a position of the primary side is easily and precisely achieved during assembly.
- the secondary side is niers relative to the pivot point of the door hinge and thus the door is arranged so that it dips under the primary side when the door is open. This means that the secondary side can be stowed away safely and in a particularly space-saving manner when the door is open. It is an embodiment that the secondary side is attached to a door pane of the door. This enables a particularly close arrangement to the primary side and a particularly flat design.
- the housing can in particular have the shape of a flat, cuboidal hollow body, one broad side of which is open.
- the open edge of the broad side of the housing can be designed like a flange.
- the housing has an omega shape in cross section.
- the at least one secondary coil and the secondary electronics are housed in the housing. It is a further development that the secondary electronics, in particular a carrier or a circuit board thereof, is or has been clipped or latched into the housing, screwed or hot caulked.

- a wet bonding process in particular so that no water can penetrate into the interior of the housing.
- the housing can be a housing that is closed on all sides or fully enclosed.
- the primary side and the secondary side are accommodated in a respective housing. In this way, protection of the primary side against environmental influences is also provided. It is a further development that the at least one primary coil and the primary electronics are accommodated in the housing of the primary side. In a further development, the housing of the primary side is a fully enclosed housing. It is a further development that the primary electronics, in particular a carrier or a circuit board, is or has been clipped or latched, screwed or heat-caulked into the associated housing. In particular, the housing of the primary side can be designed as a casing, for example a plastic casing.
- coil (s) and electronics in a common unit, in particular in a common housing, also results in a particularly close arrangement of the electronics (e.g. the power and driver electronics) on an associated coil, so that particularly short cable paths are achieved. This in turn avoids inadequate signal quality.
- the household appliance is a microwave appliance and the housing of the primary side and / or the housing of the secondary side have a shield against microwaves.
- the shield can be a thin shielding plate, e.g. with a thickness of about 0.35 to 0.5 mm.
- the shielding can be removed on the side of the housing facing the respective other coil when the door is closed.
- the shielding is impermeable to microwaves, but permeable to alternating magnetic fields and / or radio signals exchanged between the primary side and the secondary side by means of a transformer.
- This embodiment can additionally or alternatively have a shield against external induction signals, which makes it particularly advantageous for cooking devices with an induction function.
- the household appliance is set up to use the at least one energy transmission device to detect a door open position, in particular the presence of a closed door.
- a door open position in particular the presence of a closed door.
- This can be reliably implemented due to the short range of the transformer coupling in the millimeter range.
- the presence of a closed door can be recognized by the fact that an electrical signal can be tapped on the secondary side, in particular a power signal for operating a consumer. If the door is opened, the transformer coupling breaks down. Based on the presence of a transformer's coupling, it can therefore be determined whether the door is open or closed.
- the energy transmission device can replace the previously existing mechanical door contact switch.

- the primary side 8 and the secondary side 9 and thus also the primary coil 10 and the secondary coil 12 are only separated from one another by a small distance.
- the coils 10, 12 can be coupled by means of a transformer: e.g. If the primary coil 10 is excited by an alternating current, the magnetic alternating field generated thereby can induce an induction voltage in the secondary coil 12, which is made available as operating voltage to the door-side consumer after processing by the secondary electronics 13 such as rectification, smoothing, etc. If the oven door 4 is opened, the transformer or inductive coupling can collapse even at small door opening angles.

This can in particular be attached to the door hinge 2 before the door hinge 4 is installed in the oven 1. This has the advantage that the assembly sequence for assembling the door hinge 4 does not need to be changed or only needs to be changed slightly.
- the oven door 4 not only has the door pane 3 serving as an outer pane, but also an inner pane 17 on the cooking chamber side and an intermediate pane 18 which Form a disk package of the oven door 5.
- the primary side 8 is arranged in front of a condensate drip channel 19 so that the drip channel 19 forms a protective wall for the primary side 8 opposite the cooking space, e.g. to protect against high temperatures, contamination, microwave radiation, etc.
- the primary side 8 has a support 20 , which prevents the primary side 8 from breaking or bending down in the event of mechanical stress, since the primary side 8 touches down on the drip channel 19 with its support 20 beforehand.
