    Field of the Invention 5 The invention relates to a rangehood for do mestic cooker having a hood for collecting fumes, a duct above the hood, a fan arranged in the duct, and a filter arrangement which is arranged in the duct, wherein the 10 filter arrangement comprises a plurality of filter pan els. Background 15 A rangehood of this type is described in EP 1 705 430. It includes a hood open at the bottom to collect the fumes rising from a cooktop. A duct, in which a fan and a filter arrangement are provided, is mounted on the 20 hood. The filter arrangement includes a plurality of fil ter panels. Summary of the Invention 25 It is an object to provide a domestic range hood of this type with improved filter efficiency. This objective is accomplished by the rangehood in accordance with claim 1. 30 Accordingly, the filter arrangement thus com prises at least one set of at least four spaced-apart bean, mutually parallel, vertical filter panels at the same height level. Between these filter panels there are formed at least one downwardly open inlet chamber and at 35 least one upwardly open outlet chamber. The air sucked into the inlet chamber can pass through one of the filter SU/AMI P107842AU00.doc 1 r 1 1 -6 11 2 panels to reach the outlet chamber and continue from there to the fan. Additionally at least one further chamber is formed between said at least four vertical filter panels, 5 which also preferably forms an upwardly open outlet cham ber. In this case, there is provided advantageously an inlet chamber between the two outlet chambers. This has the advantage that air from the cooktop can also enter the outlet chambers from the outside through vertical 10 filter panels. Based on the same consideration, it is also advantageous if each input chamber is horizontally adja cent on all sides to at least one outlet chamber. The inlet chamber is located again at the centre, so that air 15 can also pass from the cooktop through the outside of vertical filter panels into the output chamber(s). Advantageously at least two sets of mutually parallel vertical filter panels are provided. The filter panels of the two sets are arranged at an angle to each 20 other. In this way, at least nine chambers can be formed between the plates. Preferably, the plates of the two sets are arranged perpendicular to one another, so as to form rectangular or square chambers. However, they may in principle also arranged at an angle of 600 or 1200 to 25 each other, so as to form triangular or hexagonal cham bers. Brief Description of the Drawings 30 Further embodiments, advantages and applica tions of the invention can be found in the dependent claims and in the following description making reference to the figures, in which: Fig. 1 shows a rangehood with a duct with 35 partially cut walls, Fig. 2 a first embodiment of a filter ar rangement, SU/AMI P107842AU00.doc 12 1 ))A1,) 3 Fig. 3 a rotated view of the filter arrange ment according to Fig. 2, Fig. 4 a view of the filter assembly of Fig 2 from below, 5 Fig. 5 a schematic cross section through the filter assembly of Fig. 2, Fig. 6 an exploded view of the filter ar rangement according to Fig. 2, Fig. 7 a side view of a second embodiment of 10 a filter arrangement, Fig. 8 a horizontal section through the fil ter arrangement along line A-A of Fig. 7, Fig. 9 a vertical section through the filter assembly along line B-B of Fig. 7, 15 Fig. 10 a representation of the filter ar rangement of Fig. 7 with partially disassembled filter panels, and Fig. 11 a representation of the filter assem bly of Fig. 7, wherein the bottom filter panels are shown 20 completely disassembled. Ways of Implementing the invention 25 Definitions: The directions "down and "up" are defined by the direction of air flow in the filter arrangement, with the air flow passing through the filter arrangement from the bottom to the top. Accordingly the hood is arranged 30 below the duct. The expressions "horizontal" and "vertical" are defined in the same manner. Accordingly, a filter panel is arranged vertically when it is oriented parallel to the longitudinal direction of the duct and horizon 35 tally when it is perpendicular thereto. SU/AMI P107842AU00.doc 1.O 11 1-1 4 Fig. 1 shows a rangehood with a downwardly open hood 1, on which a duct 2 is mounted. In duct 2, there is provided a fan 3, as well as a filter arrange ment 4. The fan 3 transports the air or the fumes from 5 the hood 1 through the filter arrangement 4 and passes them through an outlet opening 5. The rangehood can be an open rangehood, which re-emits air cleaned by the filter assembly 4 back into the room, or a vented rangehood that passes the clean air 10 to an exhaust system through which it is extracted from the room and released for example into the open. Fig. 2-6 show a first version of the filter arrangement 4, the structure of which is described below. Basically the filter arrangement 4 has an up 15 per and a lower section 4a, 4b, respectively. The two sections have essentially the same outside diameter. The upper section 4a forms a fan chamber 6 (Fig. 5, 6), in which the fan 3 is arranged. The lower section 4b is a filter area, in which most of the air is filtered. 20 In the lower section there are provided the above mentioned vertical filter panels 8, 9 which are all arranged at the same height level. In the embodiment shown, these filter panels form a first, inner module 10 of four inner filter panels 8 arranged perpendicular to 25 each other, as well as an external module 11 of four outer filter panels 9 arranged perpendicular to each other (Fig. 6). The second module 11 surrounds the first module 10. Each module 10, 11 is formed by four mutually perpendicular filter panels 8, 9, respectively, and has a 30 rectangular, preferably square, cross-section. It is also conceivable that the modules each are formed each from three or more than four filter panels and have for exam ple triangular or hexagonal cross sections. The first module 10 surrounds an inlet cham 35 ber 14 (see Fig. 4), which is open at the bottom, i.e. in direction of the hood 1, and closed from above by a lid 15 (see Fig. 5, 6). The lid 15 can be rendered airtight SU/AMI P107842AU00.doc 10 11A1 5 or as a filter. At least one outlet chamber 16 is formed between the filter panels 8 or 9 of the first and the second module (Fig. 5). It is open at the top, i.e. in direction of the fan 3, but closed from below by a bottom 5 17. The bottom 17 can be airtight or designed as a fil ter. As can be further seen in Fig. 5, the plates 8 or 9 are arranged at a distance from the wall 18 of the duct 2, so that between the wall 18 and plates a riser 10 channel 19 is formed for the fumes from the hood 1. The fan chamber 6 is located above the verti cal filter panels 8, 9. At least one of the vertical walls of the fan chamber 6 is made by a fan chamber fil ter panel 20. This is arranged spaced from the wall 19, 15 so that the riser channel 19 continues upwardly along the outside of the filter panel 20 of the fan chamber. An airtight wall section 22 forms at least one more vertical wall of the fan chamber. This has the advantage that the wall in this area can be made thinner, 20 leaving more space for the fan 3. In operation the extracted fumes enter from the hood into the inlet chamber 14, as illustrated in Fig. 5, from where they can pass via the vertical filter panel 8 of the first module into the outlet chamber 16. 25 From the outlet chamber 16, the air rises upwards into the fan chamber 6 and thus to the fan 3. At the same time the air rises from the hood 1 also within the riser chan nel 19, from where it can either enter from the outside into the outlet chamber 16 or directly into the fan cham 30 ber 6. In the embodiment shown, a middle section 4c is formed by four middle section filter panels 24 is lo cated between the upper section 4a and the lower section 4b. Thus, the fan chamber 6 can be enlarged. 35 As shown particularly in Fig. 6, the filter panels 8, 9, 20, 24 are preferably made each from identi cal, preferably square, filter elements 25. In the em SU/AMI P107842AU00.doc 10 1) nil) 6 bodiment shown the filter panels 8 of the first module 10 have each one-third of the filter area of the filter pan els 9 of the second module. Thus the filter panels 9 can be built from three times the number of filter elements 5 25 than the filter panels 8 of the first module. In the present embodiment, the filter panel 8 of the first mod ule 10 are each made of three filter elements 25 and the filter panels 9 of the second module 11 of nine. For example, a frame 28 of profiled bars is 10 provided for mounting the filter arrangement 4. The frame 28 is attached to the cap 29 of the duct 2 and is sus pended within the duct 2. The outer filter panels 9, 20 and 24, which are adjacent to the riser channel 19 are mounted directly into the frame 28. To attach the first 15 module 10 to the second module 11, braces 30 (Fig. 4, 6) are provided, which extend from the lower edge of the first module to the lower edge of the second module and are hooked there onto the frame 28. Figs. 7-11 show a second embodiment of a 20 rangehood, which differs primarily from the first embodi ment in the way the filter panels are arranged and built. The filter arrangement 4 has again an upper and a lower section 4a, 4b, respectively, which operate like those of the first embodiment. 25 In the embodiment as shown, a total of four sets of filter panels 9a - 9d, 9e - 9h, 9i - 91, 9m -9p are provided in the lower section. Two of these sets are referred to as "upper sets" and include a first upper filter set 9a - 9d, and a second upper filter set 9e 30 9h. The two remaining sets are referred to as "lower sets" and include a first lower filter set 9i - 91, as well as a second lower filter set 9m - 9p. The filter panels of each individual set are parallel to each other and preferably arranged equidis 35 tantly. In the embodiment shown, each set includes four filter panels. SU/AMI P107842AU00.doc 1Q 11) A1) 7 Regarding the upper filter sets 9a - 9h, the filter panels are arranged all at the same height level. In the embodiment shown the filter panels of the two sets 9a - 9d and 9e - 9h are mounted perpendicular to each 5 other and intersect to form in the spaces between them nine rectangular chamber sections. The filter panels 9a 9d have each slots 32 extending vertically from the top to the inside (i.e. downwards), whereas the filter panels 9e - 9h have each slots 32 extending vertically from the 10 bottom to the inside (i.e. upwards). The respective width of the slots 32 is chosen to essentially match the thick ness of the filter panels so that the filter panels of the two sets can be joined to cross each other in the area of the slots. 15 The two lower filter sets 9i - 9p are built in the same manner. When stacked the chamber sections, which are formed by the sets, become vertically aligned and form the inlet and outlet chambers 14, 16, respectively (Fig. 20 8), the structures of which are described in the follow ing in more detail. Above the two upper sets of filter panels, an upper panel 33 is provided having openings 34 near the outlet chambers 16, while being closed near the inlet 25 chambers 14. Below the two lower sets of filter panels, a lower panel 35 is provided with openings 36 near the inlet chambers 14, while being closed near the outlet chambers 16. In this way, four inlet chambers 14 open at 30 the bottom are created and five outlet chambers 16 open to the top 16. All filter panels 9a - 9p are built identi cally and interchangeable with each other. In addition to the slots 32 already mentioned, they exhibit each inter 35 locking steps 38 on their vertical edges (Fig. 11). The upper section 4a is essentially built like the one of the first embodiment. Again the fan cham SU/AMI P107842AU00.doc 101 In 8 ber 6 is enclosed on three vertical sides by fan chamber filter panels 20 while one exterior wall of the fan cham ber is made of an airtight wall section 22. The air flow in the second embodiment is 5 similar to the first embodiment with the air entering the outlet chambers 16 through the inlet chambers 14 or the riser channels 19 or directly into the fan chamber 6 through the fan chamber filter panels 20. To attach the filter panels, guide means are 10 provided in the area of the vertical edges of the filter arrangement. In the embodiment of Figs. 10 and 11 these are rods 40, which are fixed to the cap 29 of the duct 2 and suspended therefrom. Fastening means are provided at the bottom of the guide means, e.g. in the form of nuts 15 42 (Fig. 9) screwed to the rods 40. The rods 40 can be replaced by corner pro files 43 mounted in the corners of the duct 2, as shown in Fig. 8 using dotted lines. The filter panels and their filter elements 20 include preferably two spaced-apart, air-permeable cover ing layers, between which the actual filter material, in particular activated carbon, is arranged. The lower section 4b of the filter arrange ment can be adapted to the required specifications, or 25 filter arrangement of different stages of expansion can be offered based on the same design. For example a sim pler arrangement with smaller filter areas can replace the lower sections 4b. E.g, the lower two sets of filter panels of the embodiment of Figs. 7-11 can be eliminated 30 and the lower panel 35 is mounted adjacent to the upper sets of filter panels so that the inlet and outlet cham bers are reduced to only half the height. In a further variant, the rangehood can be delivered even without the entire lower section 4b. In this case, the bottom of the 35 fan chamber 6 is replaced by a horizontally arranged fil ter panel or cap. SU/AMI P107842AU00.doc 1Q 1) )A1) 9 In summary, it can be stated -that the domes tic rangehood has a filter arrangement, which has at least one set of four spaced apart and mutually parallel vertical filter panels 9a - 9p arranged at the same 5 height. Between the filter panels 9a - 9p at least one inlet chamber 14 open at the bottom and at least one out let chamber 16 open at the top are formed. This increases the available surface area of the filter in a compact construction. 10 The number of parallel filter panels can be higher than four, e.g. six or eight, which increases the number of inlet and outlet chambers accordingly. While in the present description preferred embodiments of the invention are described, it should be 15 noted that the invention is not limited to those and can be implemented in other ways within the scope of the fol lowing claims. Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
