Definitions

  • the present invention relates to an attachment for an extractor hood, in particular, the additional device is an air treatment device.
  • the hood consists of a kit that can take into account the actual available height at the installation site.
  • an extractor hood which consists of individual units.
  • a carrier assembly, a filter unit, an electronics unit, a drive motor unit, a connecting pipe and a telescopic chimney are used to mount a cooker hood.
  • this structure can solve a number of installation problems, this hood does not solve the problem of different supply of air from the hood to an accessory, especially the supply line from different directions to the attachment.
  • a treatment by means of oxygen activation is used in addition to a pure filtration.
  • Such a type of air treatment is for example in the DE 10 2006 008265 A1 described.
  • harmful gases are generated, such as ozone. In order to prevent leakage of these gases, it is necessary to be able to hermetically seal the container of the air treatment.
  • the object of the present invention is therefore to provide an attachment for an extractor hood, which can be installed in a simple manner and reliably in different installation orientations to the extractor hood.
  • an attachment for an extractor hood in particular an air treatment device comprising a housing in which at least two air inlets are provided.
  • the attachment is characterized in that it includes at least one pre-assembly unit having a closure device for temporarily closing one of the air inlets of the housing and having at least two installation orientations with respect to the housing.
  • a fume extraction device is referred to, which is suitable for sucking and removal of contaminated air from a space located below the extractor device space.
  • the hood can represent a fume extractor for sucking and cleaning of fumes and vapors.
  • a device which can be connected to an extractor hood for cleaning the sucked air.
  • the attachment may be located in the hood itself. Preferably, however, the attachment is a separate component that is connected to the extractor hood. This connection is usually via conduit.
  • a pre-assembly unit is understood to be an assembly in which at least two components are combined to form a unit.
  • the components are connected to each other, that is attached to each other.
  • the components are permanently connected to each other.
  • Insoluble in this context means that the components can only be separated from each other with the help of tools and preferably only with destructive methods.
  • the attachment of the components to each other takes place during assembly of the units of the additional device at the production of the additional device.
  • the housing of the attachment may be integrally formed.
  • the housing consists of at least two components.
  • the air inlets on the housing in particular represent openings through which air can pass directly or via a line into the auxiliary device.
  • the air inlet can therefore also serve to receive and / or guide the end of a conduit in the inventive device.
  • the temporary closing of the air inlet via the closing device takes place by moving the closing device relative to at least one further part of the pre-assembly unit.
  • Installation orientation is understood to mean the orientation which the pre-assembly unit can assume during the installation of the auxiliary device in the auxiliary device, that is, with respect to the parts of the housing.
  • the assembly of the pre-assembly and the other units is called.
  • the installation can be done at the installation of the attachment, for example, on a kitchen cupboard or in the vicinity of the installation, for example, in the kitchen.
  • a closing device on a pre-assembly unit, which can be aligned differently with respect to the housing of the auxiliary device, it becomes possible to close different air inlets by means of the closing device.
  • the choice of which air inlet is to be closed by the closing device is made after the installation orientation of the auxiliary device.
  • the air flow from the extractor hood to the attachment is taken into account here.
  • installation orientation is understood in this context, the relative position of the attachment to the extractor hood.
  • the closing device is part of the pre-assembly unit, the relative position of the closing device to be closed air inlets in the possible installation orientations on the housing already during manufacture, that is, the assembly of the individual units of the attachment at the place of manufacture. In this way, in comparison to a fastening of the closing device to a unit during installation, the secure closure of the air passage can be ensured by the closing device. A determination of which of the air inlets of the housing to be temporarily closed by the capping unit after the installation of the attachment, does not take place at the production of the attachment.
  • a single preassembly unit is sufficient for different installation orientations of additional equipment.
  • the manufacture and storage of different pre-assembly units for a single accessory can be eliminated in the present invention due to the at least two installation orientations. Rather, one and the same preassembling unit is connected to the housing of the attachment when installing the attachment in the required installation orientation and so made sure according to the installation orientation of the attachment to the hood that the closure reliably close the temporarily to be closed in the selected installation orientation of the accessory air inlet inlet can.
  • the attachment has at least two mounting orientations.
  • Installation orientation refers to the orientation the accessory must have with respect to the cooker hood at the installation site in order to perform the task attributed to the attachment.
  • the installation orientation is dependent in particular on the air duct between the extractor hood and additional device.
  • the attachment thus has at least two air inlets, which are provided on different sides of the attachment. For example, an air inlet on the left side and another air inlet on the right side of the attachment are provided.
  • the attachment can be connected to the left side or with its right side via an air duct with the hood.
  • the housing of the attachment has fewer installation orientations than the pre-assembly unit.
  • the installation orientation of the housing in this case describes the orientation that the housing can take against a surface, for example, a room wall or a cabinet wall or a cabinet surface.
  • An installation orientation of the housing is, for example, placing the bottom of the housing on a cabinet surface.
  • Another installation orientation would be in this case, the laying of the cover of the housing on the cabinet surface, that is, a rotation of the housing by 180 °.
  • the housing can only assume an installation orientation, namely, that the bottom of the housing facing downward.
  • the pre-assembly unit has a carrier to which the closing device and at least one further component is fastened.
  • the relative position of the closing device is fixed to the other component.
  • This embodiment has the advantage that, in particular in the case of a pivotable closing device, obstruction of the movement by other components can be avoided since these are fixedly secured in the pre-assembly unit at a fixed distance from the closing device.
  • the further part, which is fastened to the carrier may be an electronic or mechanical component, such as a switch, which is actuated by the closing device, or an actuating unit, via which the closing device is actuated.
  • the relative position to the closing device itself is important so that the individual components can perform their function.
  • the closure device preferably constitutes a pivotable element.
  • the advantage of this embodiment over displaceable elements is that the air inlet to be closed by the closure device can also rest against a wall of a component which is adjacent to the wall or support the closing device is attached, is angled, that is at an angle greater than 0 °, for example, 90 °.
  • the closure device is a flap which is pivotally mounted on the pre-assembly, in particular the support of the pre-assembly.
  • the closing device is connected in the edge region of the pre-assembly, in particular of the carrier of the pre-assembly.
  • an air inlet can be closed by pivoting, which is in an area which can be at different angles to the surface of the carrier by the closing device, which is for example a flap.
  • the area in which the air passage is provided may lie in the same plane as the carrier. But it is also possible that this is located in a surface which is offset from the plane of the carrier by an angle of for example 90 °.
  • a part of the preassembling unit, in particular the carrier of the preassembly unit, preferably represents an outer wall of the additional unit.
  • the attachment includes a cover for closing one of the air inlets.
  • the cover can be detachably connected to the air passage, in particular be introduced into this.
  • the cover is a cover plate that can be mounted in the air inlet.
  • the attachment represents an air treatment device having at least one oxygen activation device.
  • the device for oxygen activation may for example be an ozone source. Particularly in this type of oxygen activation, the reliable temporary closing of the air inlet by the closing device is of particular importance.
  • a device for oxygen activation a device is referred to in the context of the present invention, in which an ion generation and / or an ozone production takes place. By enriching the contaminated air with ions and / or ozone, the air quality of the polluted air can be improved.
  • a plasma module can be used as a device for oxygen activation.

  • the attachment 2 is shown on the left side of the drawing in a first installation orientation and in the right side of the drawing by dashed lines in a second installation orientation to the extractor hood 1.
  • the air duct 12 is connected to the right side of the attachment 2
  • the air duct is connected to the left side of the attachment 2.
  • the position of the Verrohrungsan gleiches on the attachment 2 thus depends on whether the attachment 2 is to be installed on the upper cabinet 4 right or left of the hood 1.
  • FIGS. 2 to 5 the construction of an embodiment of the air treatment device 2 according to the invention is shown.
  • FIG. 2 shown embodiment of the attachment 2 is an air treatment device.
  • This has a box-shaped housing 21 with a bottom 213, a ceiling 2141, a front 211, a back and two end faces 212.

  • the pre-assembly unit 24 is separable from the bottom 213 and the side walls 212 of the housing 21.
  • the releasable connection with the side walls 212 and the bottom 213 may be, for example, a plug connection, a clamp connection or a connection by insertion into rails or other holders.
  • the air line 12 When installing on one of the upper cabinets 4 right of the hood 1, the air line 12 must be performed by the hood 1 to the left side of the attachment 2 and connected to this side with the attachment 2. It should be noted that due to the small installation space above a kitchen cupboard 4 usually a guide the air line 12 via the attachment 2 to the right side of the attachment 2 is not possible.
  • an air inlet 2121 is therefore also provided in the left side wall 212. This was at the installation, which in FIG. 3 described was closed by the cover plate 22.

  • the flap 242 In order to be able to close the end of the air line 12 or the air passage 2121 temporarily, the flap 242 must be brought into the vicinity of the left side wall 212 of the housing 21.
  • the flap 242 can be detached from the carrier 241 without disassembly. Rather, the pre-assembly unit 24 is removed from the attachment 2 and installed in a rotated position by 180 °, that is, in a second installation orientation. This condition is in the FIG. 5 shown.
  • FIG. 5 results in this installation orientation of the attachment 2, the provided at the bottom of the housing 21 component 231 is provided at the position in which it in the other in FIG. 3 shown installation position was arranged.
  • the installation location of the component 231 may be left as a function of nature or as a function of the dimensions of the component 231. If the component 231 is, for example, a plasma generating device or another such component, the weight is usually so great that it can not be fastened to the cover 214 of a housing 21, without the wall thickness of the cover 214 and thus the Weight of the housing 21 need to increase unnecessarily. For this reason, the example in FIG. 3 shown arrangement for a connection of the air line 12 from the other end face 212 are not completely rotated by 180 °.
  • the present invention can thus be solved, for example, the installation problem with respect to an accessory, which is connected via a short piping to a kitchen extractor hood and installed on a kitchen cupboard.
  • the extractor conveys the polluted air sucked in via the hob through the piping to the auxiliary unit, where the aftertreatment of the air takes place.
  • the aftertreated air is returned to the kitchen from the attachment.
  • the final installation orientation in the manufacture of the attachment is not clear.
  • the carrier is a part of the attachment and can in particular represent the rear wall of the attachment.
  • This pre-assembly group which includes the carrier and the closing device, can be manufactured independently of the actual installation situation at the end customer and is delivered to the customer along with all remaining equipment components. All other device components, such as a cover plate that covers the unneeded breakthrough in the side wall for connecting an air line, can only be installed after the end user's knowledge of the installation position.
  • the pre-assembly group is designed so that all, in particular both possible mounting positions or installation orientations of the pre-assembly (flap mounted right or left side) are directly feasible. According to the present invention, therefore, the rear wall with all pre-assembled components rotated by 180 ° can be installed.
  • devices that are structurally dependent on the specific installation situation may contain imponderables for the final device design. These prevent complete device final assembly ex works. To minimize this shift of the installation effort to the location of the device installation as far as possible final assembly is only feasible if installation-dependent device components are structurally combined to pre-assembly and these pre-assembly together with the remaining equipment components on as many conceivable mounting positions at the customer are customizable. In this way, final assembly takes place as much as possible at the factory, leaving control of the manufacturing and testing process in the hands of the plant as much as possible. Factory standards and quality standards are thus better monitored, especially in view of the lack of control over work quality during final assembly and installation of the device at the customer by external personnel.
