Definitions

  • This invention relates to ovens, especially those in which the oven and/or associated grill are gas energised.
  • a problem with such ovens is that combustion products tend to discolour the wall in front of which the oven is situated and/or prevent space above such ovens being used e.g. for cupboards. This is a particular problem with built-in installations.
  • the invention provides an oven including a duct for combustion products which extends downwardly around the outside of the oven cavity and which terminates at an opening beneath and at the front of the oven cavity, and a fan for driving the combustion products along the duct towards the opening.
  • the fan which may be mounted at the mouth of the downwardly extending portion of the duct, advantageously, draws room air into the duct as well as combustion products, and the flow of room air may be used to cool controls for the oven as well as serving to dilute the combustion products expelled into the room. Cooling air may also be drawn between two panels of a double panel door before entering the duct.
  • the single cavity 1 of the oven is heated by a gas flame from a burner 2, and a forwardly-directed gas grill 3 is also contained within the cavity.
  • a door indicated generally by the reference numeral 10 for the oven is pivoted about a horizontal axis at its lower end to permit access to the oven.
  • the oven is built-in rather than free-standing, and is mounted on a plinth 4 and covered by a work surface 5. Controls 6 for operating the oven are located just beneath the work surface 5.
  • the roof of the oven is covered by a layer of insulation 1a, and the rear covered by a layer of insulation 1b.
  • Layers of insulation (not shown) also cover the side walls of the oven.
  • a duct indicated generally by the reference numeral 12 is provided for expelling combustion products at low level forwardly into the room.
  • the duct There are three sections to the duct, namely, a section 12a extending above the roof of the oven into the left-hand end of which gases are drawn by a fan 13, a section 12b which extends downwardly at the rear of the oven, and a section 12c which extends underneath the oven cavity and terminates in front of the oven cavity and beneath it in a louvered opening 14, the louvres serving to deflect the emerging gases downwardly.
  • the flame from the main burner 2 in the oven is supported by air entering the oven beneath the door and travelling beneath the floor 1c of the oven.
  • Combustion products from this flame escape through aperture 15 (arrows 'HOT') in the roof of the oven and enter section 12a of the duct, beneath a partition 16 which divides the section 12a into an upper and lower section.
  • the combustion products are drawn along this lower section by the fan 13 and driven down the sections 12b and along the section 12c.
  • air from the room is drawn into both upper and lower parts of the section 12a, down section 12b and along section 12c, so that the gases blown into the room are significantly diluted, for example, in the ratio of ten parts of room air to one part of combustion products.
  • room air enters above the door and underneath a lip 19 referred to below and enters the duct section 12a below the partition 16 through openings 20 in a flange 21 surrounding the oven cavity.
  • Room air also enters these openings 20 by being drawn up the interior of the door of the oven, which consists of front and rear panels 10a, 10b and which is open at the bottom and has openings at the top corresponding to openings 20, this serving to lower the temperature reached by the outer panel 10a of the oven door in use.
  • the upper wall of the duct 12a has an aperture 22 to draw in air beneath a hob unit 23 (arrows 'COLD') which is inset into the work surface 5, in order to reduce the temperature of the lower surface of the hob. Air can enter this region from the periphery of the hob 23.
  • the grill can only be operated when the door 10 is retained in an open position, and combustion products from the grill 3 diffuse forwardly and are drawn through the opening 20 by the combination of the suction of the fan 13 and the guiding effect of the lip 19 (arrows 'HOT'), as well as passing through aperture 15, into the portion of the duct section 12a below the partition 16. These combustion products are mixed with cold air drawn in above and below the controls 6 and expelled at low level into the room, as in the oven mode.
  • combustion products are expelled forwardly into the room lending the oven the ability to be mounted in a built-in environment e.g. with a continuous work surface 5 which butts the wall at the rear.
  • the combustion products are considerably diluted with room air to reduce their temperature and, it is believed, this together with the low-level outlet, will render the device more acceptable to users.
  • the fan may consist of axially extending blades arranged around the circumference of a cylinder extending into the plane of the paper as seen in the drawing, but other types of fan could be used if desired.
  • the invention is applicable to the case where the main burner of the oven is replaced by electrical heating elements, the only combustion products coming from the grill. Equally, the invention is applicable to the case where the grill consists of electrical heating elements and a gas main burner is provided. In the latter situation, cooking fumes are drawn into the flue and discharge at low level when the grill is being used.
  • the grill 3 is contained within a separate cavity 24 of the oven located above the main oven cavity 1.
  • a double cavity oven may be mounted underneath a cabinet or facia panel 25.
  • the grill is rearwardly facing instead of forwardly facing.
  • the upper cavity 24 has a door 26 pivoted about the horizontal axis at its lower edge and, in addition to the grill 3, also has a burner 27.
  • An interlock mechanism ensures that flap 28 at the rear of the top oven is open when the door of the top oven is open, so that there is adequate ventilation when the grill is used, which can only happen when the door of the top oven is open. (The flap is closed when the oven door is closed because the output of the main burner is substantially less than that of the grill). Combustion products from the top oven enter vertically extending duct 29 and are drawn into the region of duct 12a above the partition 16 via aperture 22 which is considerably enlarged in this embodiment.
  • the top oven may be used with either the main burner 27 or the grill 3 and, in either event, combustion products are drawn into the duct 12 and expelled into the room at low level as in the embodiment shown in Figure 1.
  • the top oven may contain only a main burner or only a grill unit, and the main oven could if desired be heated by electrical heating elements.
