Definitions

  • the present invention relates to a combination device comprising an extractor device with a fan and a hob with at least one cooking module and a device housing.
  • Cooking processes usually produce steam and vapors.
  • Fume extractor devices known, by means of which the vapors and vapors can be sucked off and cleaned.
  • combination devices are known, for example, in which an extractor device is arranged below the hob.
  • Such a combination device is described, for example, in DE 20 2013 005 303 U1.
  • a housing for the heating or hob heating and control electronics is provided on the underside of the hob. Below the housing there is a fan housing for two or more radial fans that suck in air from a cooking vapor suction chamber below.

  • the cooking module can represent an electrical heating module with a heating coil.
  • the cooking module is preferably an induction module and is also referred to as an inductor.
  • the induction module preferably comprises at least one induction coil.
  • An induction module is understood in particular to be a component that is provided to generate an alternating magnetic field by converting electrical energy, which is used to induce eddy currents and / or magnetic reversal effects in an at least partially ferromagnetic food container, for example a pot, which are converted into heat .
  • the combination device furthermore comprises an extractor device.
  • An extractor device is a device by means of which air, in particular contaminated air, for example in the form of fumes and vapors, can be sucked down from the space above the hob.
  • the air in the extractor device is preferably cleaned and released as purified air or clean air from the extractor device and the combination device.
  • the extractor device preferably includes filters, in particular grease filters and odor filters.
  • the extractor device comprises at least one fan, which can also be referred to as a blower.
  • a fan is understood here as a unit consisting of a fan wheel with a motor and a fan housing surrounding the fan wheel.
  • the fan preferably represents a radial fan, in particular a radial fan with blades curved forwards, and the fan housing preferably represents a spiral housing, which can also be referred to as a worm housing.
  • the fan has at least one suction opening.
  • the fan has an air outlet opening on the fan housing.
  • the suction opening is introduced into the fan housing, or formed by it, and represents the opening through which air can be sucked into the fan housing through the fan wheel, which can also be referred to as an impeller.
  • the suction opening is perpendicular to the axis of rotation of the fan wheel.
  • the combination device also has at least one air inlet opening for the extractor device.
  • the air inlet opening is the opening through which air enters the combination appliance from above the hob.

  • the air inlet opening is arranged in a recess in the hob, in particular a recess in the cover plate of the hob.
  • the air inlet opening can lie in the recess of the hob or be formed by it.
  • the air inlet opening can be formed, for example, by a filter holder for filters of the extractor device, which is introduced into the recess.
  • the cooking modules of the hob are offset from the recess in the hob.
  • the combination device is characterized in that the electronic components are arranged in the combination device in a first and a second level.
  • the first and the second level are at different heights in the device housing.
  • a level at which at least one circuit board with at least one electronic component is arranged is referred to as the level of the electronic components.
  • the first level is preferably at a lower height in the device housing than the second level. The first level is therefore also referred to as the lower level and the second level as the upper level.
  • the space requirement of the boards in the width and depth directions of the combination device is minimized.
  • the circuit boards can be positioned in the device housing in such a way that they are protected from contamination and can also be arranged in the vicinity of the components that are operated or controlled by them.
  • components of the power electronics and the operating electronics are referred to as electronic components.
  • Power electronics are required to operate the hob and in particular the cooking module.
  • the power electronics are used to supply the cooking module or modules with electrical energy.
  • the power electronics can transform the electrical energy, for example with regard to the voltage shape or the current.
  • the power electronics can include, for example, filter components and control electronics.
  • the elements of the power electronics are, for example, rectifiers for rectifying the AC voltage of the household electricity network, inverters and switching devices, for example for power management.
  • power electronics are required to operate the extractor device and, in particular, the fan.
  • the electronic components of a plane are held on at least two circuit boards in the plane and the at least two circuit boards are arranged at a distance from one another in the respective plane.
  • This division of electronic components on different circuit boards and a corresponding spaced arrangement in the respective plane can further enhance the advantages of the invention.
  • the space available in the device housing can be optimally used, since the size of the circuit board can be smaller and this can therefore also be arranged in smaller free spaces in the device housing.
  • the first level of the electronic components is arranged above the fan housing of the fan.
  • the fan housing and the fan are preferably arranged on the bottom of the device housing. Since the fan housing must have a large size in order to achieve sufficient power to suck in the vapors and vapors and also through, for example, the air outlet of the fan housing, which is usually a channel provided tangentially on the fan housing, the space available is low adjacent to the fan.
  • the filter unit of the extractor device is usually provided above the fan housing. However, this has a smaller dimension than the fan housing, at least in the width direction. This means that more installation space is available in the level above the fan housing and the circuit boards of the first level can therefore be installed flexibly.
  • the arrangement above the fan housing has the advantage that liquids that accidentally get through the air inlet opening enters the device housing, and runs from the fan housing, the electronic components of the first level can not reach.
  • the second level of the electronic components lies below the cooking modules of the hob.
  • This arrangement of the second level has the particular advantage that it is close to or adjacent to the cooking module or modules.
  • the first level comprises electronic components for the extractor device and for the hob. Since the first level is below the second level, and is preferably above the fan housing, this is both in the vicinity of the fan, in particular the fan motor, but also not far from the cooking modules.
  • the second level comprises electronic components only for the hob.
  • the levels of the electronic components each have at least one metal plate for receiving at least some of the electronic components.
  • the metal plates are used to hold or hold at least one circuit board.
  • the metal plate can therefore also be referred to as a carrier.
  • the combination device has a lower motor level, a first level of the electronic components located above, a second level of the electronic components located above and a cooking module level located above.
  • the invention preferably has a four-level structure.
  • FIG. 1 a schematic front view of a combination device
  • FIG. 2 a schematic perspective view of the lower components of an embodiment of the combination device
  • FIG. 3 a schematic perspective view of the lower and middle components of the embodiment of the combination device according to FIG. 2; and FIG. 4: a schematic sectional view of the embodiment of the combination device according to FIGS. 2 and 3.
  • FIG. 1 a schematic front view of an embodiment of the combination device 1 according to the invention is shown.
  • the combination device 1 consists of a hob 2 and an extractor device 3, of which only the air inlet opening can be seen in FIG.
  • the hob 2 consists of a cover plate 20 and cooking modules 21 arranged below the cover plate 20, which in particular represent induction modules.
  • two cooking modules 21 are provided.
  • a recess 200 which forms the air inlet opening of the extractor device 3, is made in the cover plate 20.
  • the recess 200 is made in the middle of the width of the cover plate 20 and extends in the depth direction.
  • the recess 20 preferably has a rectangular elongated shape.
  • the length of the recess 20, that is to say its dimension in the depth direction, preferably corresponds to the length of the cooking modules 21.
  • the cooking modules 21 are arranged to the left and right of the recess 200.
  • the cooking modules 21 lie below the cover plate 20 and are preferably attached to the underside of the cover plate 20.
  • a filter unit (not shown) is arranged below the cooking modules 21 under the recess 200.
  • the fan 30 of the extractor device 3 is arranged on the bottom of the fan housing.
  • the motor 300 of the fan 30 is aligned so that the motor axis of the motor is vertical.
  • a collecting container for liquids is arranged on the bottom of the device housing, adjacent to the front of the fan housing.
  • a housing, onto which the filter unit can be introduced, is placed on the fan 30.
  • Circuit boards with electronic components of a first level are arranged above the fan 30 and in particular above the fan housing (see FIG. 2).
  • the housing on which the filter unit can be arranged is arranged laterally offset in each case a circuit board with electronic components.
  • circuit boards of a second level of electronic components are arranged above the electronic components of the first level of electronic components. Two boards are also provided in this plane, each extending over the entire depth of the device housing and lying on the opposite sides of the device housing. There is a gap between the boards of the second level, into which a filter unit can be inserted.
  • the Circuit boards of the second level are held on metal supports, each of which has a partition wall facing the other metal support,
  • the components of the combination device are thus distributed in such a way that the width of the device housing and thus of the combination device can be reduced, in particular 60 cm.
  • the components in the combination device are arranged in a four-layer distribution.
  • the configuration according to the invention that is to say the arrangement of the components, differs in that the electronic circuit boards of the combination device are in two different planes, which in particular can be arranged in the same relative position.
  • additional circuit boards such as fan control circuit boards, power supply and, if applicable, electromagnetic filters are preferably separated from the induction power boards in the vertical direction.
  • the first level is the motor level I, in which the motor is arranged on the floor of the device housing.
  • the second level represents the first electronics level II.
  • the second electronics level III is separated from the first electronics level II.
  • Structure-specific circuit boards 5 are arranged in the second electronics level III.
  • the cooking modules are located in the fourth level IV and this level can therefore also be referred to as the induction level.
  • This vertical separation allows the construction of a more flexible distribution so that ventilation-related components can be placed.
  • this new design concept allows electronic components to be placed on different levels. This means that a narrower body of the combination device, the width of which is directly proportional to the dimensions of all circuit boards with electronic components that are provided in one plane. Therefore, a design of 60cm wide combination devices instead of the known 80cm wide combination devices is possible. The fact that the circuit boards with electronic components are separated does not affect the performance or performance of the combination device, since the performance or performance can be ensured by other components such as metallic supports or specific housings.
