Definitions

  • a hood construction for such ventilators which includes a forwardly projecting bonnet adapted to be folded or swung away into a housing when the ventilator is not in use, whereby, the hood will occupy a minimum of usable space over the cooking surface, to provide a compact, unobtrusive unit.
  • a typical ventilator of the type to which this invention relates comprises a hood which is positioned, as nearly as possible, directly above the cooking surface for collecting the gases rising therefrom, a blower which accelerates the gases to an exhaust port or through filters which cleanse the air of odors and entrained grease and smoke particles.
  • Such ventilators are usually although not necessarily mounted below overhead kitchen wall cabinets so that they will occupy relatively little usable wall :area.
  • the eificiency of ventilators of this type depends in substantial degree upon the area and position of the hood, which preferably should project over the entire cooking surface to collect most if not all of the column of gases rising from the range beneath it.
  • the area enclosed by the hood should approach or equal the area of the cooking surface, or should at least be as large as is reasonably compatible with available space.
  • the hood of a typical ventilator installation will project from several inches to more than a foot outwardly of the front of the main ventilator housing. Most of the time, when the ventilator is not in use, this hood serves no immediate purpose and is relatively obtrusive, projecting outwardly from the wall as it does.
  • This invention is predicated upon a ventilator hood construction which includes a frontal extension or bonnet which is movable between an open position, in which it in effect greatly increases the area and the air-collecting eifiClBIlCY of the hood, and a closed position, in which it folds into a housing afforded by the rear portion of the hood.
  • the hood is especially adapted to be mounted beneath wall cabinets above a cooking surface, the bonnet folding into its housing in such manner that in closed position its top surface lies substantially in the plane of the front of the cabinets, and blends in or harmonizes attractively with the cabinets.
  • closed position thi hood is substantially more compact and less obtrusive than the conventional hoods of past constructions.
  • the air-collecting efiiciency of the hood with the bonnet in open position will equal or exceed the efiiciency of present types, since its area and position are not as limited as past constructions in repect to the optimum considerations.
  • a preferred embodiment of the hood of this invention includes a housing having top, rear, front, and side walls which is open at the bottom, and a bonnet having a sloping top panel and triangular end panels.
  • the upper rear corners of the bonnet are slidably connected to the housing by pivots which ride in vertical slots at the front of the housing side walls.
  • Foldability of the bonnet into the housing is efiected by means of a wheel and guide arm mechanism which causes the top panel of the bonnet to move into vertical position flush with the front edge of the housing as the bonnet is urged rearwardly toward the housing. This mechanism holds the bonnet in either closed or open position without the necessity "ice I 22 of utilizing positive catches, so that the bonnet can quickly be moved from either position to the other.
  • FIGURE 1 is a front perspective of a typical installation of a ventilator in accordance with the invention, showing the bonnet in closed position;
  • FIGURE 2 is a front perspective of the installation shown in FIGURE 1, showing the bonnet in open position;
  • FIGURE 3 is a diagrammatic view showing the manner in which the bonnet cover insert may be removed in order to substitute a different insert for it;

  • Ventilator 20 generally comprises a housing 25 having a front panel 26 and a bonnet 27 which, in the open or extended position shown in FIGURE 2, projects forwardly from housing 25 below front panel 2s.
  • Housing 25 includes a rear wall 39, side or end walls 31 and 32, and a top wall 33 all of which may be fastened together by conventional means such as the angle brackets, tabs, and rivets shown.
  • the housing 25 is open at the bottom to collect gases rising into it from a cooking surface below, not shown.
  • a conventional blower also not shown, is mounted inside the housing and accelerates the gases collected by the hood to an exhaust port.
  • Front panel 26 is secured to the top wall 33 of the housing at a position spaced rearwardly of the front edge of the top wall, and does not extend the full width of the housing to the side walls 31 and 32, for reasons explained more fully hereinafter, gaps or spaces 34 and 35 being defined between the ends of front panel 26 and housing side walls 31 and 32 respectively.
  • an outwardly-extending flange 36 having a lip 37 is provided at the lower edge of front panel 26.
  • Control knobs 4-0 and 41 for operating the blower may be mounted on front panel 26 as shown.
  • a mounting plate 42 is secured inside the housing adjacent each side wall 31 and 32 Each plate 42 encloses and mounts a mechanism designated generally by 44 for guiding and balancing the motion of the bonnet 27 when the latter is swung into or out of the housing 25, and for holding the bonnet in the closed or open positions shown in FIGURES l and 2.
  • the left mounting plate 42 includes a rear portion 45 which is spaced inwardly of the housing side or end wall 31 by a right angular oifset portion 4-6, a section 47 which is facially secured to the inside surface of side wall 31, and an inwardly offset, vertically slotted strip 50 formed forwardly of portion 47.
  • the rear edge of mounting plate 42 is secured to rear wall 30 by a bracket 51.
  • the mounting plate which is secured to the other housing side wall 32 is similar.
  • Bonnet 27 has side walls 52 and 53 which are generally triangular in outline, between which a bonnet top panel 54 is secured by means of tabs and rivets as shown.
  • a rigidifying rib 55 extends longitudinally across bonnet top panel 54.
  • a curved nose panel 56 is connected between the side panels 52 and 53 by means of tabs and rivets, and has a downwardly offset rear edge 57 which overlaps the front edge 60 of the bonnet top panel 54.
  • a trim strip 61 conceals the joints where top panel 54 and nose panel 56 meet side panels 52 and 53, and includes a pocket 62 at the position at which top panel 54 overlaps nos panel 56.
  • a decorative cover insert 63 is removably secured over bonnet top panel 54.
  • This-insert 63 is rectangular in outline and is secured over the top panel between the trim strips 61, 61, and is held in place at its lower or forward edge by a cover strip 64 which is fastened through top panel 54 and nose 56 by means of spaced screws 65.
  • the length of cover strip 64 is equal to the Width of the bonnet, the ends of the cover strip being received in the pockets 6'2, 62 formed in the trim strips 61, 61.
  • the upper or rear edge of the decorative insert 63 is engaged under a forwardly extending flange 66 riveted at the rear edge of the bonnet.
  • the manufacturer is enable economically to supply ventilators which will harmonize with a wide range of colors and decors.
  • the entire unit can readily be adapted to harmonize with different surroundings.
  • cover insert 63 Installation of the cover insert 63 is effected by removing the nuts holding down screws 65, pulling the cover strip 64 upwardly and outwardly at its midsection so that the straight line distance between its ends is decreased, whereby its ends are disengaged from the pockets 62, 62 in the trim strips 61, 61, sliding the particular insert selected into position as shown FIGURE 3, and engaging its upper edge under flange 66. Cover strip 64 is then remounted and fastened in place to hold the insert securely in position.
  • the mechanism 44 whereby collapsibility of the bonnet 27 is effected may now be described.
  • the mounting plate 42 which is at the left of the housing is provided with a detent 67 which comprises a bearing spacing a circular guide wheel 70 outwardly of the mounting plate in the chamber 71 which is defined between portion 45 of the mounting plate and housing side wall 31 (see FIGURE A pin 72 through detent 67 pivotally mounts the wheel 70 to plate 42.
  • a second detent 73 is formed in the cover plate below detent 67 and holds a nylon rider 74 over which the wheel 70 can freely slide even if twisted downwardly about pin 72.
  • detents '75 and '76 which correspond to detents 67 and 73 respectively, so that the manufacturer can produce a single form of mounting plate which can be used at either end of the housing, the mounting plate which is at the right of the housing being identical to the plate 42 which is at the left of the housing, but oppositely oriented.
  • detents 75 and 76 serve no purpose in the plate 42 which is at th left of the housing but comprise the pivot and rider mounting of the plate which is at the right of the housing, the mechanisms 44 at each side of the housing being similar.
  • Guide wheel 70 is provided with two outwardly extending stops 80 and 81 which are preferably lanced from it.
  • An elongated guide arm 82 is pivotally secured to guide wheel 70 by a pin 83 at a point between stops and 81.
  • Arm 82 passes through a slot 79 in offset portion 46 of mounting plate 42, and is secured at its front end to bonnet 27 by a screw 84 which passes through an aperture 85 formed adjacent the slanting top edge of bonnet side panel 52 forwardly of the rear edge of the bonnet.
  • a tension spring 86 is connected between one of a plurality of holes 87 in an offset portion 88 of guide arm 82 and the lower edge of mounting panel 42.
  • the offset front strip 50 of mounting plate 42 presents a vertical slot 96 extending to a point adjacent housing top panel 33.
  • a T-headed bolt 93 is secured by a tab 94 to the upper corner of bonnet side panel 52, and slides in slot 90, as is best shown in FIGURE 6.
  • the T-head of boits 93 preferably is rotatable so that the bonnet can be removed from the housing for shipment or cleaning as desired.
  • a lower slot 91 is provided in strip 50 for purposes of symmetry as previously explained, into which a nylon rider 92 is pressed. Rider 92 bears against the inside surface of bonnet end panel 52 to provide a sliding bearing for the bonnet as it is swung into or out of closed position. Similar structure is provided at the right end of the bonnet and housing.
  • FIGURES 8 and 9 illustrate the general operation of the guide mechanism 44 as the bonnet 27' is swung from 'open position, shown in FIGURE 9, to closed position,
  • each rear upper corner of the bonnet is secured to the housing 25 by a bolt 93 which, when the bonnet is in open position, is positioned at the bottom of slot 90.
  • Guide arm 82 abuts stop 81 of wheel 70, so that counterlockwise rotation of wheel 70 is positively prevented. Being thus constrained, the bonnet is held by gravity in open position.
  • bonnet When the bonnet is in closed position, its top panel 54 is positioned vertically, forward of housing front panel 26, substantially coplanar with the edges of the housing and the front of the cabinets between which it is mounted (see FIGURE 4). It thereby conceals the control knobs 40 and 41 and the interior of the housing.
  • the bonnet side panels 52 and 53 extend into the housing through gaps 34 and 35 between the ends of housing front panel 26 and the left and right mounting plates 42, and it it for this reason that panel 26 does not extend the full width of the housing to the side walls.
  • flaps 95 and 96 are swingably mounted to housing top panel 33 at either end of front panel 26, and are urged by springs 97' toward the back surface of front panel 26.
  • these flaps are in the position shown in FIG- URES 6 and 7, the lower ends of the fiaps projecting downwardly behind the upper edge of the bonnet.
  • the rear edges 100 of the bonnet side panels 52 and 53 push the flaps 95 and 96 upwardly and inwardly to the position shown in FIGURE 4.
  • the hood is preferably made from sheet metal in accordance with conventional manufacturing techniques. It is adapted to receive a standard blower, filter and light, which can be mounted within the housing without interfering with the collapsibility of the bonnet. With bonnet in open position, the invention provides a hood which is of large enough area to be an effective collector, yet which can be collapsed so as to occupy relatively little usable space.
