The present invention relates to a fume extractor hood, particularly a flat screen hood, as well as to an input module for a fume extractor hood. In conventional fume extractor hoods, an input module, which can comprise input switches of electronic or mechanical nature as well as indicating devices, is usually provided at the front side of the fume extractor hood.
Particularly in the case of flat screen hoods which have a flat withdrawable screen slide, this is usually equipped at the front side with a furniture decoration strip. The apparatus in the inactive state thereby merges unobtrusively and in visually harmonious manner into the line of top cupboards of a built-in kitchen. The input module in these fume extractor hoods is therefore usually mounted at the side or above or below the screen.
Moreover, in German Utility Model G 91 13 763.2 a fume extractor hood is described in which the electrical switching device is integrated in a hollow grip rod.
Since the input module is arranged at a fixed location in the fume extractor hood, it can happen in the case of different users of the fume extractor hood that the input module is difficult to see or operate or the visual sensibilities of the user are disturbed. Change of the user of a fume extractor hood can occur, for example, in the case of built-in kitchens in rented dwellings when the tenant changes.
The object of the present invention is therefore to create a fume extractor hood which can be readily adapted to the requirements of individual users, can be of flexible design and can be produced with low productions costs.
The invention is based on the recognition that the object can be fulfilled in that at least one further position for the input module is provided beyond a first position for the input module.
The object of the present is therefore fulfilled by a fume extractor hood comprising at least two receiving regions for selectable, detachable reception of at least part of an input module.
By selectable reception there is understood in the sense of this invention that the position of the input module can be changed between the at least two receiving regions, i.e. the input module can be selectably positioned at one or the other receiving region. An input module in the sense of this invention comprises at least one switch element, which can have a mechanical or an electrical switch, and can in addition comprise at least one indicating device. The input module is usually used in the form of a switch strip with or without an indicating device. The reception of at least part of the input module can on the one hand ensure a secure retention of the input module, but on the other hand make possible the actuation of the switch elements and viewing of the indicating device.
According to a preferred form of embodiment the at least two receiving regions are represented by cut-outs in at least a part of the housing of the fume extractor hood. Defined fastening regions for the input module are created by provision of cut-outs at the housing. The cut-outs can be provided in the form of depressions at the surface or, however, in the form of, for example, longitudinal grooves. Retention of the input module at different positions can be realised by these cut-outs and recessing of at least a part of the module into the housing can be made possible. The visual appearance can be improved particularly by virtue of the latter advantage.
Preferably at least one interface for the input module is provided at the fume extractor hood, at least one interface is associated with each receiving region and the interface is an interface for current supply and/or for signal transmission. Through provision of such an interface all functions of the input module can be realised at each of the receiving regions and the input module supplied with current. Alternatively, the interface can serve exclusively for signal transmission. In this case the input module can be equipped with an own current supply, for example in the form of a battery. By signal there is understood in the sense of this invention, in particular, the transmission of actuating signals from the input module to control means in the fume extractor hood as well as transmission of status signals from control apparatus of the fume extractor hood to the input module.
Preferably the interface is represented by an electrical contact. However, it is also possible to use as interface a receiver for infrared beams or radio signals. In this case the input module comprises a transmitter which can exchange information with the receiver or can at least pass on information to the receiver. For this purpose, particularly for the exchange of information, the receiver at the fume extractor hood is preferably also designed for transmission of signals and/or radiation and the transmitter of the input module is similarly designed for reception of signals and/or radiation. Actuating data and status data, in particular, are transmitted by way of transmission medium of infrared radiation or radio signals.
The fume extractor hood according to the invention can comprise at least one support plate allowing star-shaped wiring for the at least two receiving regions. In this case the interface can be realised at the at least two receiving regions in the form of electrical contacts and the wiring cost can be kept small.
Preferably the receiving region comprises means for detachable connection with the input module. These means can be realised in the form of the material of the receiving region. If, for example, the control element is designed to be magnetic, then the receiving region of the fume extractor hood is to be designed to be magnetisable. However, other means, such as, for example, means for shape-locking and/or force-locking joint connections, are also usable.
Preferably these means are represented by detent means, screw devices and/or push-in strips. Detent lugs or detent depressions can be provided as detent means. Moreover, it is possible to provide, as screw-connection device in the region of the receiving region, screw domes or simple bores for the passage of a screw. Finally, edges, flanges and other projections, which preferably extend longitudinally, can be used as push-in strips. The input module then has respectively corresponding counter-members for co-operation with the means at the receiving region. Through these means for detachable connection there can be created a stable retention with, at the same time, comparatively simple possibilities of detaching.
Preferably the fume extractor hood comprises at least one panel having at least one cover, which can be detachably received in the at least one receiving region for the input module. For the detachable connection there are preferably used means which are provided at the cut-out for the detachable connection with the input module, particularly detent, screw and push-in devices, wherein the cover has corresponding counter-members for co-operation with the means at the receiving region. As cover, which a part of the panel represents, there is denoted in the sense of this invention a part which in the installed state at least partly covers the cut-out provided for the input module. According to the invention the panel is so designed, or consists of the appropriate number of covers, that the entire cut-out can be covered. Through the provision of at least one panel at least one receiving region in which no input module is received can be covered, which improves the visual appearance of the fume extractor hood and facilitates care, particularly cleaning, of the fume extractor hood. If the panel consists of several covers, then these preferably respectively form separate components which can be individually inserted in the corresponding receiving region.
According to a further form of embodiment at least two covers can be received in each receiving region. Through division of a panel into at least two covers a flexible use of the covers can be made possible. Thus, for example, a part of the panel, i.e. a cover, can be used for the purpose of carrying a trade mark logo or a type designation, whereagainst the other cover can be kept neutral.
With particular preference, the dimensions of at least one cover correspond with the dimensions of the input module. The dimensions of this one cover correspond, at least with respect to width and length, with the dimensions of the input module. With respect to height and thus depth of penetration into the housing of the fume extractor hood the cover can have a smaller extent. Through correspondence of the dimensions of at least width and length it can be made possible to also use the means for detachable connection, which are provided in the receiving region, for the cover. Beyond that, in the case of provision of several covers in a panel, covers which do not correspond with the geometry of the input module also remain in the receiving region in the case of insertion of the input module into this and thus, for example, lead to a fluid transition between input module and housing.
In a particularly preferred form of embodiment three covers are provided for at least one receiving region, wherein the dimensions of one of the covers correspond with the dimensions of the input module. Preferably the middle one of the three covers corresponds with the dimensions of the input module. In this case on the one hand a symmetrical appearance can be created and on the other hand the use of the covers can be simplified.
Preferably the fume extractor hood is represented by a flat screen hood which has at least one withdrawable region and wherein the at least two receiving regions are provided at the withdrawable region. As withdrawable region there is denoted the screen pull-out or drawer in which also at least the front filter can be provided. A part of the withdrawable region can additionally be the grip strip which can, for example, be designed as a furniture decoration strip.
The receiving regions can be provided at the lefthand side, righthand side, upper side and/or front side at this withdrawable region. Through provision of these different positions of the receiving regions the fume extractor hood can be used in variable manner. Thus, for example, the input module can be changed, depending on the respective user, from the righthand to the lefthand side. Account can thereby be taken an ideal manner of right-handedness or left-handedness of different users. In addition, the size of users can be taken into consideration by the variable provision of the control element at the front side or at the upper side. At the upper side the cut-out is preferably provided in an inclined region so as to facilitate viewing of this region.
According to a further aspect the object of the present invention is fulfilled by an input module for an electronically controllable domestic appliance, particularly for a fume extractor hood. The input module comprises at least one switch element and represents a unit separate from the domestic appliance. Moreover, the input module comprises at least one contact device by way of which the input module can be brought into contact with at least one of several interfaces, which are provided at the domestic appliance, for signal transmission between the input module and the domestic appliance.
As domestic appliance there can come into consideration, apart from a fume extractor hood according to the present invention, also, for example, a baking oven or a dishwashing machine. Through design of the input module in a separate unit, which comprises a contact device, the position of the input module can be easily changed, in the case of provision of different receiving regions at the domestic appliance, by removal and insertion into a different receiving region. The input module according to the invention therefore represents a flexible input module.
Preferably the input module comprises at least one contact device by way of which this can be brought into contact with at least one of several interfaces, which are provided at the domestic appliance, for current supply. The contact device for current supply can be identical with the contact device for signal transmission. The advantage of this form of embodiment consists in that an own current supply does not have to be provided in the input module, but the current supply provided for the entire domestic appliance can also be used for the input module.
According to a further aspect of the invention the object underlying the invention is fulfilled by an input module for an electronically controllable domestic appliance, particularly for a fume extractor hood, which comprises at least one switching element, wherein the input module represents a unit separate from the domestic appliance and, physically spaced from the domestic appliance, co-operates with an interface, which is provided for the domestic appliance, for the signal transmission. In the case of this refinement of the input module this can be used at a spacing from the domestic appliance. With a fume extractor hood, for example, the input module can be placed on the worktop and is thus easy for the user to look at and use.
In one form of embodiment the input module has, for co-operation with the interface for signal transmission, a cable connected with the domestic appliance. The advantage of this embodiment consists in that a current supply of the input module can take place from the domestic appliance by way of the cable.
According to a further form of embodiment the input module comprises, for co-operation with the interface for signal transmission, a transmitting device co-operating with a receiving device at the domestic appliance. The transmitting device and receiving device are preferably designed for transmission of infrared radiation and/or radio signals. In this form of embodiment the input module can be moved completely freely in space as long as the range of the transmitting or receiving device is not exceeded.
In this form of embodiment the input module preferably comprises a current supply unit, which can be represented by, for example, a battery.
The features and advantages described with respect to the fume extractor hood are correspondingly relevant and to that extent applicable also to the input module and vice versa.
The invention is described in more detail in the following for a fume extractor hood on the basis of figures which represent non-exclusive examples of the present invention, wherein:
A part of a fume extractor hood according to the invention is illustrated in
The construction of an input module 2 according to the invention is explained in more detail in the following with reference to
As further connecting means two screw domes 235 are arranged at the input module at the rear side thereof, i.e. in the region surrounded by the wall of the base part 323. An electrical contact with an interface 62 can, in the illustrated form of embodiment, take place from the input module 2 by way of a contact tongue 24 which extends substantially along the width of the circuitboard 25 and optionally comprises a projection which extends over the height of the input module. The contact tongue 24 is illustrated in, in particular,
In
The selectable introduction of the input module 2 into individual receiving regions 121, 122, 131 of the fume extractor hood 1 will now be described in the following with reference to FIGS. 7 to 13. In
Respective projections in the form of collars, which extend into the interior of the drawer 12, are provided in the regions 1221 and 1222. The collars of the parts 1221, 1222 are constructed in different heights. The collar 1224 of the middle region 1221 ends closer to the surface of the drawer 12 than the collars 1223 of the side regions 1222. In particular, the collars 1223 of the side regions 1222 in the illustrated form of embodiment have at the ends thereof flanges extending in the direction of the receiving region 122. By virtue of this displaced collar height, different elements such as, for example, covers 3, 4 for the input module 2 can be introduced in simple manner into the receiving region 122.
The introduction of the short covers 4 can, for example, take place as shown in
The input module 2 or a long cover 3 can be selectably introduced into the intermediate space formed between these two short covers 4. This can selectably take place by way of screw connections effected in the screw domes 235 provided on the rear side of the input module 2 or by way of corresponding screw domes provided on the rear side of the long cover 3. Alternatively, detent lugs or other detent elements can be provided at the receiving region 122 and engage with the openings 234 at the side of the base part 232 of the input module 2. In like manner a long cover 3, which simply has openings in the outer wall, can be introduced into the receiving region 122, particularly in the intermediate space between the short covers 4.
A grip strip 13 in which two short covers 4 and a long cover 3 or an input module 2 are received is illustrated in FIGS. 9 to 11. The grip strip 13 consists, in the illustrated form of embodiment, of a hollow profile member, wherein a receiving region 131, which substantially has the shape of a longitudinal groove, is provided at the front side of the hollow profile member. The receiving region 131 can have substantially the same form as the receiving region 122 described with reference to
A short cover 4 introduced into the lateral region of the receiving region 131 is shown in cross-section in
An input module 2 or a long cover 3 in the receiving region 131 is illustrated in cross-section in
The introduction of an input module 2 or of the covers 3, 4 into the lateral region of the drawer 12 is now described with reference to
As shown in
After the different positions of the input module 2 or the covers 3, 4 and the various possibilities of fastening have been described, one possibility of wiring the various receiving regions in the drawer will now be described with reference to
A cable cover 124, below which different cables for current supply and actuation of individual functions of the fume extractor hood can be guided, is arranged at the upper side of the drawer 12. In addition, arranged in the middle region of the drawer in the illustrated form of embodiment is an auxiliary plate 6 on which contacts, with which lines 61 are connected, are provided. Three contacts are arranged on the auxiliary plate 6 in the illustrated form of embodiment. A respective contact 62 is provided at the end of the lines 61. These contacts are arranged at the positions representing receiving regions 121, 122, 131. The contact tongue 24 of the input module 2 can come into contact with the current supply and the signal processing of the fume extractor hood by way of these contacts 62 and thus the functionality of the different functions of the input module can be guaranteed. The provision of an auxiliary plate 6 by way of which lines 61 can be connected with the contacts 62 allows a star-shaped wiring. This means, in particular, that it is merely necessary to lay, from control apparatus associated with individual functions of the fume extractor hood, one line each time in the fume extractor hood 1, preferably under the cable cover 124. These lines can be connected with the auxiliary plate 6. Separate lines 61 for the contacts 62, which are in individual receiving regions 121, 122, 131, therefore have to be provided only from the auxiliary plate 6. A saving of lines is therefore achieved by this form of wiring.
Although two input modules 2 are indicated in
A perspective view of the drawer 12 from below is illustrated in
The present invention is not restricted to the illustrated and above-described forms of embodiment. Thus, the receiving regions can be executed in various forms. These can have rectangular openings, square openings, round openings or openings in the form of a longitudinal groove with or without rounded sides. Preferably the receiving regions at least at the upper side of the drawer and the front side of the grip strip are of the same shape. Although the receiving regions are illustrated in the figures at the upper side and the front side respectively in the middle of the width of the drawer it is possible to provide these at different positions. Thus, for example, a respective receiving region can be provided at the front side of the grip strip on the left and the right. The same applies to the upper side of the drawer. The receiving regions are preferably provided at the sides of the drawer not only at the righthand side, but also the lefthand side. The size of the receiving region of the sides of the drawer preferably corresponds with the withdrawal travel of the drawer, i.e. the spacing between the front edge of the lateral housing part of the fume extractor hood and the rear side of the grip strip.
The size of the receiving regions, particularly of the cut-outs, can be designed so that these can receive merely one input module or one long cover 3. However, it is also possible to design the size of the receiving regions so that in addition to an input module one or two covers can be received.
The shape of the input module can also differ from the form shown in the figures. Thus, for example, the head part can have a flat surface instead of the rounded surface. In this connection it is to be noted that preferably the head part has a greater width than the base part so as to ensure a secure retention in the receiving region. However, the head part of the input module can also correspond with the width of the receiving region.
It is possible within the scope of the invention that an input module, which was removed from the fume extractor hood, is replaced merely by a single, preferably long cover. The provision of further short caps can be eliminated in this form of embodiment. However, it is also preferred to additionally provide at least one cover in the receiving region also in the case in which the input module is installed in the fume extractor hood. This cover can, for example, be used for the provision of trade mark logos. With particular preference, apart from the input module in addition two preferably short covers are provided in a receiving region, wherein the input module can be replaced each time by a long cover.
The receiving regions are preferably so designed at the fume extractor hood according to the invention that the same input module can be received in each of the receiving regions without constructional changes. The same applies to the covers which are similarly designed to be exchangeable between the different receiving regions. The form of the receiving regions, for example through provision of collars with different collar heights, can vary from receiving region to receiving region. However, it is also within the scope of the invention to design all receiving regions to be the same with respect to the fastening mechanism.
The materials used for production of the input module in the covers are preferably selected with reference to the material which was used for the housing of the fume extractor hood. The panel is thereby not immediately apparent to the observer. The covers are preferably made of a non-conductive material in order to avoid risk to the user due to mains voltage even in the case of inadvertent contact with one of the interfaces. The material for the cover can preferably be, for example, aluminium, aluminium alloys or plastic. The covers are preferably represented by extruded aluminium profile members.
As an additional safety precaution the connections to the fume extractor hood can be executed in protected low voltage. Wiring of the individual receiving regions is not restricted to the form of embodiment illustrated in
The position of the contacts by way of which the input module can be contacted with the fume extractor hood is not restricted to the receiving regions, in particular cut-outs. It is also possible, for example, to design lines, by way of which the contacts are connected with the corresponding control apparatus in the fume extractor hood or optionally an auxiliary plate, to be of such length that the end of the line having the contact for connection with the input module can be pulled out of the fume extractor hood by way of a receiving region. In this case the control element can be used in a position outside the fume extractor hood. Moreover, it is possible to provide an extension cable at a contact fixedly provided in the receiving region, the cable in turn being able to be contacted with the input module.
Although essentially an input module for a fume extractor hood was described, the input module according to the invention can similarly be used in the described manner for other domestic appliances. Panels consisting of covers can also be used with these.
Through the fume extractor hood according to the invention and the covers according to the invention a simple and economic variant of a fume extractor hood able to be adapted in simple manner to the individual needs of the user can thus be provided. Through the different receiving regions provided in the housing of the fume extractor hood the user himself or herself or a kitchen installation specialist can in simple manner take an input module from one position to another position without having to carry out significant mounting operations. In addition, the visual appearance in the case of the fume extractor hood according to the invention remains pleasant, independently of the position of the input module, particularly through use of panels comprising covers. The fume extractor hood according to the invention additionally represents a substantial possibility of variation with respect to different brand and appliance variants. These can be premounted in simple manner during production. In particular, one or more covers can be printed with the respective trade mark logos, whereagainst the input module can be constructed to be neutral with respect to marks. The appliance variant is produced only later in the production process by the inexpensive small cover, which in a given case consists of plastics material.
