Definitions

  • the application relates to a fume collecting device according to the preamble of Patent Claim 1.
  • the application also relates to a drive module according to Claim 10 and to a process according to Claim 11.
  • fume collecting devices i.e. devices intended to be arranged above a cooker to draw off cooking fumes, steam, etc. during cooking.
  • a cooker fan is a fume collecting device intended to be arranged in a separate kitchen flue.
  • the cooker fan has an internal motor for driving a fan, in which the fan is normally integrated with the motor to form a unit, which fan is activated during use to draw off fume-laden air through the kitchen flue.
  • the cooker fan can alternatively be equipped with an external motor for driving the fan, which external motor is placed in an attic or on the ceiling.
  • a cooker hood is another type of fume collecting device, which is arranged in a ventilation system.
  • a cooker hood comprises a damper and, where appropriate, a timer for controlling the damper, as well as a transformer for 25 controlling an external motor for operation of a ceiling fan.
  • the damper is opened, whereupon a forcing flow is obtained, so that, for example, fume-laden air is drawn off through the ventilation system.
  • a cooker hood has no internal motor for driving a fan.
  • a further type of fume collecting device is a so-called Alliance, which is a cooker hood provided with a motor with fan, intended to be arranged in a ventilation system. During use, apart from opening the damper, an internal motor is also used to further improve the working.
  • One advantage is that the air quantity can be increased without increasing the size of the external motor with fan.
  • Yet another type of fume collecting device is a carbon filter fan, this being cooker fans in which there is no facility to draw-off the fume-laden air to some flue.
  • the carbon filter cleans the air of the cooking fumes.
  • a design hood is a fume collecting device, normally a cooker fan, which is not intended to be built into a cupboard, but is intended to be arranged freely on the wall or in connection with a so-called kitchen island, where the look of the cooker fan is of importance.
  • These design hoods normally have a chassis portion having a lower part in which transformer, lighting, fan, electronics components for the control thereof, filter, motor, etc. are arranged, as well as a chimney part which is intended to cover the kitchen flue, which in turn is intended to lead away the food fumes.
  • a problem with the increased number of variants of the chassis portion is that the installation of components, etc. must be matched to the design, thereby increasing the production costs.
  • DE 94 16 271 U1 discloses a fume collecting device comprising a chassis portion and a drive module.
  • the chassis portion hosts buttons for controlling the drive module.
  • DE 200 05 154 U1 discloses a fume collecting device according to the preamble of claim 1 for mounting on the wall or ceiling, with a housing funnel having an intake and filter section, being oriented on the bottom part of the funnel and having at least one fastening part, and a fan, being driven by a motor.
  • the fume collecting device is characterized in that it consists of combinable modules, which are detachably interconnected.
  • the fume collecting device further comprises a control module, which is mounted in the funnel.
  • One object of the present invention is to provide a fume collecting device which allows more efficient production of the same.
  • the objects are procured with a fume collecting device via which fume-laden air is intended to be captured, incorporating a chassis portion which, inter alia, constitutes a substantial part of the exterior of the device, wherein the fume collecting device comprises means for procuring and controlling the intake, a drive module comprising a control module being arranged as a separate unit and independent from the rest of the fume collecting device with the aim of providing for the said procurement and control, and wherein the control module comprises control devices for controlling a damper and/or motor and wherein the control module is mounted in a housing of the drive module, or in connection with the upper portion (12) of said housing (10, 50).
  • the drive module comprises devices for controlling the damper and/or motor. Control for a drive module for a cooker hood is therefore obtained, in which the damper is controlled and/or external motor is controlled; for a cooker fan, in which the motor, and hence the fan, is controlled; or an Alliance, in which the damper and motor with fan are controlled.
  • the fume collecting device further comprises a control module comprising the said control devices.
  • the arrangement of the control devices in the control module facilitates fault-finding in the said devices.
  • the working of the control module can be checked before this is arranged in the drive module. The exchange costs and servicing are also reduced.
  • the control module is configured to be arranged in the drive module. This enables in simple fashion a function checking of the drive module with mounted control module prior to the completion of the fume collecting device.
  • the control module and the drive module can be configured such that the control module can be fitted into the upper part of the drive module. This enables the control module to be arranged in the drive module without the flow through the drive module being disturbed by the control module.
  • the drive module comprises at least one damper arranged to be moved between a closed and a substantially open position, in which open position the fume-laden air is arranged to be discharged through the drive module.
  • the inclusion of a damper in the drive module produces a cooker hood in which the cooker hood function is seated in the drive module, which is independent from the design of the chassis portion. Adjustment of the damper is simplified, since the adjustment of damper and air flow looks similar for each cooker hood.
  • the damper is made up of a number of disc-shaped elements arranged one on top of the other, in which one of the disc-shaped elements is integrated in the drive module.
  • the individual disc-shaped elements are simple to produce, at the same time as, assembled into a unit, offering a damper with good and reliable working.
  • An upper portion of the drive module can constitute the lowermost disc-shaped element of the damper.
  • One of the disc-shaped elements can form a first hatch device and another of the disc-shaped elements can form a second hatch device, in which the first hatch device is intended to be operated by a user and the second hatch device is intended to be adjusted by an installation engineer.
  • the first hatch device can also be adjusted by an installation engineer.
  • the hatchdevices are laterally slidable, which enables the adjustment.
  • the provision of two adjustable hatch devices means that the damper can be optimized firstly for normal ventilation flow, and secondly for a more powerful flow, which can be used, for example, during cooking. The more powerful flow is procured by opening of the first hatch device by the user.
  • the first hatch device can be a swing hatch and the second hatch device can be in the form of a sliding hatch.
  • the drive module comprises a fan for sucking in fume-laden air.
  • a fan for sucking in fume-laden air.
  • the inclusion of a fan in the drive module produces a cooker fan in which the cooker fan function is seated in the drive module.
  • the fan can be driven with an external or internal motor.
  • the drive module comprises a motor for driving the fan. This means that the whole of the cooker fan function is seated in the drive module.
  • the drive module comprises a housing in which alternative devices for alternative functions for the fume collecting device are intended to be arranged. This produces a simple configuration for enabling different functions of the drive module, such as cooker hood, cooker fan and Alliance.
  • the housing can be is preferably substantially parallelepipedal. With such a configuration of the housing, it is easy to mount devices in the housing and also easy to mount the housing on the chassis portion.
  • the drive module can comprise an interface which is configured to constitute a fastening to the chassis portion.
  • the interface enables the drive module to be easily fastened to the chassis portion, so that the fastening is substantially the same for the drive module, regardless of the function of the drive module and the design of the chassis, especially its lower part.
  • a process for producing a fume collecting device comprises the step of choosing a drive module from amongst a group of drive modules which are suited to fume collecting devices of different types.
  • Such fume collecting devices comprise cooker fan, cooker hood, Alliance and carbon filter fan.
  • a control is chosen from amongst a group of control modules which are suited to fume collecting devices of the said different types.
  • the working of the control module can be checked in a separate step. This check can be made by connecting a monitoring member to connection terminal boards of the control module.
  • the checked control module is then mounted in the chosen drive module or in connection with the upper portion of the housing, whereafter it is also possible to check the working of the drive module with mounted control module.
  • a chassis portion is chosen from amongst a group of chassis portions of different configuration, whereupon the fume collecting device is completed by the arrangement of the drive module, with control module mounted therein, in the chosen chassis portion.

  • Many different models of the cooker fan, cooker hood and Alliance can be cost-effectively produced, since the drive module is substantially the same for the respective fume collecting device, and only lighting and filters are not included in the drive module.
  • the large volumes lie in the production of the drive modules, which are then mounted in the chassis portion.
  • the fastening of the drive module to the chassis portion is intended to be the same for all models.
  • the design of the lower part of the chassis portion can here range from large volumes down to single piece production.
  • the present invention results in simplified adjustment of the damper, since adjustment and measurement of the air flow, adjustment of the damper, and, where appropriate, adjustment of output voltage from the transformer look substantially the same for each cooker fan, cooker hood and Alliance, regardless of the outer design of the product, i.e. the look of the chassis portion. The same applies to servicing.
  • the knowledge is acquired to service all products.
  • the components are seated in different places, the dampers facing in different directions, different printed circuit boards, different encapsulations, etc., which calls for product training for a greater number of products.
  • the number of articles is also reduced, resulting in additional cost savings.
  • the mounting method is always the same, which simplifies assembly.
  • the respective drive module looks the same. The components are seated in the same place.
  • Fig. 4 shows schematically a perspective view of the control module 30 according to one embodiment of the present invention.
  • the control module 30 is dimensioned in such a way that it can be fitted in the housing 10; 50 of the drive module 1a; 2a; 3a according to any of the embodiments according to Figs. 1a , 2a , 3a .
  • One advantage of the control module 30 being able to be arranged in the drive module 1a; 2a; 3a is that function checking of the drive module 1a; 2a; 3a with mounted control module can easily be carried put at the factory.
  • the fitting of the control module 30 in connection with the upper part of the housing of the drive module 1a; 2a; 3a means that it advantageously does not obstruct the flow through the drive module 1a; 2a; 3a.
  • the control module comprises a printed circuit board comprising devices for controlling transformer, fan and lighting, in which the lighting is arranged outside the drive module in connection with the lower part of the chassis portion, as well as a transformer for controlling the internal fan motor and/or external motor.
  • the control module comprises so-called connection terminal boards to which connecting leads are coupled, which connecting leads are connected to transformer, fan motor and/or damper.
  • the control module comprises just one printed circuit board, which comprises devices for controlling damper and lighting.
  • the control module also comprises a transformer 34.
  • the transformer can be arranged on the top side of the control module such that it is accessible from the top side of the drive module even after the control module has been mounted in the drive module. Switching inside the transformer is thereby able to be easily done should the output voltage of the transformer require adjustment.
  • the casing of the control module is arranged to be able to receive and accommodate printed circuit board and transformer, connection terminal boards, etc.
  • the printed circuit board has the same configuration, but comprises different devices depending on the intended drive module, i.e. drive module for cooker fan, cooker hood or Alliance.
  • the casing of the control module has the same configuration for the drive modules according to the different embodiments, whereas the components in the control module vary depending on the drive module.
  • the casing is configured to be fitted and arranged in the housing of the drive module for the different embodiments and is configured such that opening of the housing, damper, and/or fan motor/fan is not affected.
  • control module is exchangeable, which is advantageous in the event of a wrong order or a swap, where a control for a central fan is desired, for example, a new control module being able to replace the previous one, whereupon the new functions are obtained.
  • control module It is also beneficial in production to install the control modules, which are then mounted in the housing.
  • the drive module can be handled in an assembly in which everything is completed, whereupon a function check is made.
  • control module It is also advantageous to be able to exchange the control module during servicing.
  • fault-finding is made easier.
  • the components in the control module are relatively expensive; if the whole of the control module is changed, fault-finding and repair of electronic components and/or the transformer can be realized, with the control module being able to be reused.
  • the replacement costs are also reduced, since the exchange can be made in shorter time. Even if it turns out that the electronics are defective, these can be repaired and reused.
  • the cooker fan i.e. the whole of the chassis, does not need to be removed, but only the control module. Finally, all that remains is to connect up the lighting.
  • damper whatsoever such as a slidable, rotatable, plastics damper, sheet-metal damper, etc. can be used.
  • the drive module according to the first, second and third embodiments has different dimensions.
  • the drive module according to the second embodiment for a cooker hood is shorter than the drive module according to the first embodiment for a cooker fan, since the cooker hood does not require any motor, whereas a fan motor is accommodated in the housing of the drive module according to the second embodiment.
  • the housing of the drive module for a cooker hood can have the same dimensions as the housing of the drive module for a cooker fan. This yields the advantage that only one size of housing needs to be produced for cooker fan and cooker hood, in which case production is simplified and the number of articles reduced. It also increases flexibility, since the housing can be used for either cooker fan or cooker hood.
  • the housing of the drive module for a cooker fan and the housing of the drive module for a cooker hood can have the same dimensions as the housing of the drive module for an Alliance, i.e. the same size of housing of a drive module for cooker fan, cooker hood and Alliance.
  • the housing of the cooker fan, the housing of the cooker hood, and the first and second housings of the Alliance can be substantially parallelepipedal.
  • the housing, or the first and second housings can assume any suitable geometric form for facilitating fastening of the same, as well as placement/fastening of components in the same.
  • the housing could, for example, be frustoconical.
  • the drive module can be used for a carbon filter cooker fan, the fan and fan motor for driving the fan being arranged in the housing.
  • a carbon filter is arranged on the drive module in order, during operation, to filter cooking fumes from the fiume-laden air.
  • the filter is arranged on the suction side of the fan.
  • the filter is arranged on the pressure side of the fan.
  • the present fume collecting device and the process for its production, effectively minimizes the number of faulty fume collecting devices delivered ex factory.
