Definitions

  • the invention relates to a hob device according to the preamble of claim 1.
  • Hob devices of the afore-mentioned type having a downdraft cooking fume extraction device are well known in the art.
  • the odor filter assembly of such hob devices are located in an area of the hob device, which is difficult to access. Consequently, it is difficult to ensure that after replacing an odor filter the odor filter is accurately located thus excluding any parasitic flow paths around the odor filter and thus jeopardizing the odor filter's function.
  • a hob device of the afore-mentioned type is, for example, known from DE 10 2018 213743 A1 . Further, it is referred to WO 2019/081271 A1 , EP 0 974 790 A2 , US 2022/178552 A1 , US 6,455,818 B1 and US 2021/055002 A1 .
  • the at least one odor filter has at least one handle arranged in its upper portion.
  • This handle which may be formed as a grip tab and/or may be made from fabric, allows the user to grab the filter easily, pull in a horizontal direction, and the odor filter is free to be removed.
  • the at least one handle can be arranged on a frame or the frame of the at least one odor filter.
  • a hob device in particular a hob device in which the odor filter housing has, above the at least one support surface and at least partially within the at least one abutment surface, a recess whose lower boundary surface forms a further support surface and whose lateral boundary surface forms a further abutment surface.
  • Odor filters usually may include activated carbon, which may have a variety of different structures. For example, it may be provided in the form of powder, pellets, bricks, and the like, which also has consequences for the design, and in particular the dimensions, of the corresponding odor filter.
  • the odor filter housing provides, in addition to the first odor filter location defined by the support surface and the abutment surface, the afore-mentioned recess as a second odor filter location having different dimensions than the first odor filter location.
  • odor filters of different design may be used with the odor filter housing according to the invention.
  • the odor filter is dimensioned such that it is supported by the further support surface when its latch connection counter means cooperate with the latch connection means of the odor filter housing.
  • the latter-mentioned odor filter may be smaller than the first-mentioned odor filter.
  • the at least one odor filter is dimensioned such that it protrudes from the further support surface when its latch connection counter means cooperate with the latch connection means of the odor filter housing.
  • the further abutment surface is formed at least partially in the shape of a grid.
  • the at least one odor filter can be dimensioned such that it be removed through the opening, thus enabling its easy removal or replacement.
  • the at least one odor filter In order to prevent the at least one odor filter to be contaminated by grease particles included in the cooking fumes, it is suggested that it further comprises a grease filter assembly, which is arranged in the flow direction of the cooking fumes between the opening and the odor filter assembly. This grease filter assembly may be inserted in the opening. In this way, the cooking fumes first have to pass the grease filter before they come upon the odor filter assembly.
  • side walls of the odor filter housing can surround the opening but can be located underneath the edges of the hob defining the opening. Due to its size, the odor filter housing cannot be removed through the opening.
  • the odor filter housing can be connected to the hob in such a way that it cannot be detached from the hob without using tools.
  • a hob device according to the invention is generally designated 100.
  • the hob device 100 comprises a hob 102 and a plurality of heating devices 104.
  • an enclosure 106 is mounted below the hob 102.
  • the hob 102 has an opening 108 connecting the space above the hob 102 with the interior of the enclosure 106.
  • a fan 110 is located in the enclosure 106, thus allowing to extract cooking fumes from above the hob 102 downwards through the opening 108 and then through a grease filter assembly 112 and an odor filter assembly 114 before expelling them at the backside of the hob device 100.
  • the grease filter assembly 112 cleans the cooking fumes from any grease or oil particles entrained together with the extracted cooking fumes.
  • the odor filter assembly 114 which in the direction of flow of the extracted cooking fumes is located downstream of the grease filter assembly 112, then further cleans the cooking fumes from any substances which might result in an unpleasant smell of the cleaned cooking fumes.
  • the odor filter assembly 114 usually comprises activated carbon, while the grease filter assembly 112 usually includes a stretched metal mesh.
  • the fan 110 is located behind the grease filter assembly 112 and the odor filter assembly 114.
  • the core of present invention is the design of the odor filter assembly 114, which will be explained in more detail referring to Figures 2 to 5 .
  • the odor filter assembly 114 comprises an odor filter housing 116 and two odor filters 118.
  • each of the odor filters 118 is supported by an associated support surface 116a of the odor filter housing 116 and abuts against an associated abutment surface 116b of the odor filter housing 116. In this position it is secured by cooperation of a latching projection 116c provided at an upper end of the odor filter housing 116 and a latching recess 118a (see Figure 3 ) provided at a frame 118b surrounding the stretched metal mesh 118c of the odor filter 118.
  • the latch connection might as well be provided at at least one of the side portions of the odor filter housing 116 and the odor filter(s) 118.
  • the latching projection(s) might as well be provided at the odor filters 118, while the latching recess(es) could be provided at the odor filter housing 116.
  • the odor filter assembly 114 has two odor filters 118.
  • the insertion surfaces 116d associated with the support surfaces 116a for the two odor filters 118 together form an inverted V-shaped arrangement, the vertex angle ⁇ of the inverted V-shape amounting to between about 100° and about 120°, preferably to about 110°.
  • the odor filter 118 further comprises a handle 118d, which is attached to the frame 118b adjacent to the latching recess 118a. The user may grip this handle 118d through the opening 108 and simply pull the odor filter 118 away from the abutment surface 116b, thus overcoming the latch connection. Then the odor filter 118 can be removed through the opening 108.
  • the odor filter housing 116 further comprises an oblique insertion surface 116d, which is located adjacent and directly connected to the support surface 116a.
  • This insertion surface 116d facilitates the re-insertion of the odor filter 118.
  • the insertion surface 116d forms a ramp guiding the odor filter 118 to the correct position. The user just needs to lower the odor filter 118 into the odor filter housing 116, and once the odor filter 118 touches the insertion surface 116d, this surface will guide the odor filter 118 simply by gravity to the correct position in which its lower edge is supported by the support surface 116a.
  • the odor filter housing 116 is designed such that it can be used with two different types of odor filters, namely a first type of odor filter 118 as is shown in Figure 4 or alternatively a second type of odor filter 118' as is shown in Figure 5 .
  • the odor filter housing 116 has above the support surface 116a, and, as may be seen from Figure 2 , and at least partially within the at least one abutment surface 116b, a recess 116e whose lower boundary surface forms a further support 116f surface and whose lateral boundary surface forms a further abutment surface116g.
  • the second type odor filter 118' analogously to the first type odor filter 118 a latch connection counter means 118a' adapted and intended to cooperate with the latch connection means 116c of the odor filter housing 116, as well as a handle 118d' facilitating its removal from the odor filter housing 116. Furthermore, the second type odor filter 118' protrudes from the further support surface 116f.
  • the further abutment surface 116g is formed at least partially in the shape of a grid, in order to allow the flow of cooking fumes therethrough.
  • Figure 2 further shows that the odor filter housing 116 has an arc-shaped extension 116h, thus widening, on the one side, its upper inlet opening 116i for cooking fumes, and providing, on the other side, a space below the arc-shaped extension 116h where the fan 110 can be arranged.
  • Figure 6 shows an exemplary embodiment of a grease filter assembly 112 having a grease filter housing 112a and two grease filters 112b which may be used in combination with the odor filter assembly 114, and may, in particular, be inserted through the opening 108 into the odor filter housing 116 after the odor filters 118 or 118', respectively, have been connected thereto.
