Definitions

• the invention relates to a built-in household appliance, preferably a built-in coffee machine, of the type explained in the preamble of claim 1.
• the device unit is defined with the aid of a receiving device, which comprises a mounting frame with an installation cavity, and is installed in a suitable structure, for example a kitchen furniture, a wall niche or the like.
• a suitable structure for example a kitchen furniture, a wall niche or the like.
• the mounting frame On its left, lower, front area, as seen from the viewer, the mounting frame has a connection box which contains a connection socket for a plug of an electrical cable which is connected to the device unit.
• the device unit To assemble the device unit within the receiving device, the device unit must first be placed on a parking area that is as close as possible and at the same height as the mounting frame. Alternatively, the device unit must be held by a second person while the first person is making the electrical connection, i.e.
• the plug into the receptacle.
• the device unit has to be inserted into the mounting frame by the operator, whereby care must be taken to ensure that the electrical connection is not disconnected again.
• the risk of unintentional disconnection of the electrical connection is increased by the arrangement of the connection box, which makes it easier to establish the electrical connection above all if the device unit can be held and not switched off, but also unintentionally disconnects if, for example, it is easier Electrical cable is jammed between the bottom of the device unit and the mounting frame and is pulled when the device unit is inserted.
• the disassembly of the device unit is equally uncomfortable, since here too the device unit must be removed before the electrical connection can be disconnected. It should be pointed out that even built-in coffee machines can reach a relatively high weight, for example 45 kg. It is very difficult to hold such a device with only one hand in order to disconnect the electrical connection with the other hand.
• the device unit can also be arranged on a type of drawer, the electrical connection being designed as a direct plug-in connection which establishes an electrical connection as soon as the drawer has been completely moved into the installation position.
• the correct electrical connection is extremely difficult.
• Such drawers especially if they carry very heavy units, never run on an exact, predetermined path. Even deviations of a fraction of a millimeter, for example due to vibrations in the drawer or due to a slightly inaccurate positioning of the device unit on the drawer, can result in the plug contacts not getting into the sockets, but striking next to them and being bent if greater force is used. so that the electrical connection cannot be made successfully.
• the invention is therefore based on the object to provide a built-in household appliance that can be easily and safely installed in a structurally simple manner.
• a built-in household appliance having a device unit, a receiving device comprising a built-in cavity, in which the device unit is arranged during its intended operation and can also be removed therefrom, and an electrical connection socket arranged on the receiving device for connection of an electrical cable arranged on the device unit, characterized in that the electrical cable can be shortened automatically.
• the built-in household appliance according to the invention can be easily and safely installed by a single person, and the electrical connection can be made quickly and safely without having to take special care.
• the appliance unit is arranged on a pull-out device and can be moved into and out of the built-in cavity with the aid of the pull-out device.
• the combination of a pull-out device on which the device unit is arranged and movable and the automatically extendable and shortenable electrical cable ensures on the one hand that the electrical connection can be made easily if the device unit is still relatively far outside the installation cavity, so that the Installation cavity is freely accessible. On the other hand, this prevents an excess length of electrical cable from becoming jammed somewhere when the device unit is inserted into the installation cavity, from exerting a pull on the electrical cable, which could lead to the electrical connection being disconnected or from preventing the correct positioning of the device unit.
• the electric cable is a spiral cable, as it is commercially available and is used for example for smaller power tools or telephone receivers.
• connection socket is arranged in the installation cavity and the cable with plug on the device unit, since many built-in household appliances are already provided with an electrical cable with plug as standard, so that the design of the household device does not have to be changed.
• the connector is special arranged in the upper, lower or rear area of the installation cavity.
• the built-in household appliance according to the invention is in particular a built-in coffee machine.
• the figure shows a perspective and schematic representation of a built-in household appliance 1 with a device unit 2, which is a built-in coffee machine in the illustrated embodiment.
• the built-in coffee machine can be one of the usual household machines for the automatic or predominantly automatic preparation of different coffee beverages, hot water and milk foam.
• the device unit 2 Defined on the device unit 2 is a front face 2a and a rear face 2b facing the operator in the installed state.
• the usual dispensing device 3 for drinks and operating elements 4 is provided on or near the front 2a, while the rear 2b bears components of an electrical connection 5, among other things.
• the electrical connection 5 contains an electrical cable 6 with a plug 6a, which is arranged on the device unit 2 in the exemplary embodiment shown.
• the electrical cable 6 is arranged at the location customary for the specific household appliance, preferably in the lower region of the rear wall and near a corner.
• the household appliance 1 as a built-in device further includes a receiving device designated overall by 7.
• the receiving device 7 defines a cavity 8 which is shaped and dimensioned in such a way that the device unit 1 can be accommodated comfortably with the electric cable 6.
• the receiving device 7 can contain, for example, a mounting housing 9 with side walls 9a and 9b, a rear wall 9c and a bottom surface 9d.
• the installation housing 9 does not necessarily have to consist of closed walls, but can have any suitable structure which, on the one hand, the size of the cavity 8 can take over the device unit 1.
• the installation housing 9 is arranged sunk into a front panel 10, wherein the front panel 10 can either be part of a piece of furniture or a wall niche or the like.
• the receiving device 7 further includes a pull-out device 11, which in the illustrated embodiment contains two pull-out rails 11 a and 1 lb, which can be designed analogously to the commercially available telescopic pull-outs, such as those used for drawers or the like.
• the pull-out device 11 can also be a pull-out tray or the like, which runs below or above the bottom 9d in guides secured against tipping.
• a connector socket 12 of the electrical connection 5 is also accommodated in the interior of the installation cavity 8.
• the connection socket 12 can be any conventional socket or the like. In which the plug 6a fits.
• the connection socket 12 can be connected to an external power network via a permanently installed line or via a further cable.
• the connecting socket 12 is accommodated in the cavity 8.
• the preferred attachment point of the connection book 12 is in the rear, right, upper area of the cavity 8, so that an operator who is right-handed can easily and easily insert the plug 6 a into the connection socket 12.
• the connecting socket 12 is fastened to the rear wall 9c, specifically in its upper right corner, where the rear wall 9c abuts the right side wall 9a as seen by the viewer and the ceiling (not shown) opposite the floor 9d.
• the easiest way to establish the electrical connection is because the viewer has a direct view of the contacts 12a of the connection socket 12 and can see them precisely, even if it is dark in the cavity 8 where the plug 6a is to be inserted.
• a possible location of the connector socket 12 would also be somewhere else on the rear wall 9c, on the side wall 9a in the vicinity of the rear wall 9c or on the ceiling, likewise in the vicinity of the rear wall 9c.
• the appliance unit 2 is arranged on the pull-out device 11 in the correct position and preferably fastened.
• the plug 6a is then gripped and the electric cable 6 is extended by pulling out its spiral windings until the plug 6a can be inserted into the socket 12.
• the device unit 2 can already be shifted somewhat in the direction of the cavity 8.
• the device unit 2 is then pushed completely into the cavity 8, the electrical cable automatically pulling back to its original, substantially shorter length and thus being able to be accommodated between the rear wall 9c and the rear side 2b of the device unit 2 in a space-saving manner without the risk that Parts of the cable get tangled in the pull-out device 11 or jam between the device unit 2 and the walls of the cavity 8.
• the device unit 2 can then be fixed in the cavity 8, for example by means of a front panel, if this is desired and necessary.
