Definitions

  • This invention relates to domestic cookers and, in particular, to such cookers as are electrically heated and controlled.
  • one or more heated compartments are surmounted by a hob unit and, for the sake of convenience of access for the housewife, the controls for the compartments and the hob unit are usually mounted near the front of the cooker, in the area where the cook-top of the hob unit overlies the front of the heating compartment.
  • a domestic cooker comprising a cabinet incorporating one or more heated compartments and an array of control components distributed transversely across the top of said cabinet, above the heated compartment or compartments, and characterised in that said cooker also includes an air management system comprising an impeller device mounted at substantially the same level as said control components, a duct coupling said impeller device to an air inlet adjacent the base of one of the sides of said cabinet, means constraining air drawn along said duct by said impeller device to flow laterally across the cooker and past said control components, internally of said cabinet, to effect cooling thereof, and an exit path for said air on the other side of the cooker.
  • an air management system comprising an impeller device mounted at substantially the same level as said control components, a duct coupling said impeller device to an air inlet adjacent the base of one of the sides of said cabinet, means constraining air drawn along said duct by said impeller device to flow laterally across the cooker and past said control components, internally of said cabinet, to effect cooling thereof, and an exit path for said air on the other side of the cooker.
  • the said duct is lined with, or formed of, thermally insulative material at least where it runs adjacent the heated compartment or compartments, or else thermally insulative material is interposed between said compartment or compartments and said duet.
  • control components are so sited in relation to the impeller device and other parts of the air management system that particularly sensitive and/or critical components are cooled first, i.e. are exposed to the cooling air prior to its having flowed past other components.
  • the cabinet is double skinned and the said duct is constrained within the cavity between the two skins, thus being concealed from view and protected against damage.
  • an air filter be included in the air management system to guard against the ingress of material which could block the air passageways.
  • a filter can be located at the inlet to the said duct.
  • the exit path comprises the cavity between two skins of the cabinet on the opposite side of the cooker to the duct and the air exits, transversely of the cooker, at or i adjacent floor level, so as to minimise draughts and also to reduce the possibility that air which has been used by the air management system, and thus heated, will be drawn directly into the inlet.
  • a domestic cooker shown generally at 1, consists of a cabinet 2 which incorporates two heated compartments, 3 and 4 and is surmounted by a hob area 5.
  • Controls for the various hot-plate areas of the hob and for the heated compartments are shown generally at 6. These controls are distributed transversely across the top of the cabinet, directly above the heated compartments, and may include sophisticated electrical or electronic components, such as a timer and programmer unit 7, which could be adversely affected by exposure to heat of the quantities generated during operation of the cooker.
  • the invention provides an air management system for cooling the controls and components 6, 7 and, in accordance with this example of the invention, the cabinet 1 is of double skinned construction and an inlet duct 8 is disposed within the cavity between the skins on one side of the cabinet.
  • the duct 8 is rectangular in cross-section and runs vertically from an air inlet 9 adjacent the base of the cooker to an upper location, at approximately the same vertical level as that occupied by the controls and components 6, 7, and at which there is mounted a fan 10.
  • the upper end of the duct 8 is closed, and the fan is constructed and positioned so as to draw air through the inlet 9, up through the duct 8 and to project the air so drawn generally into a cavity 11, behind the fascia of the cooker which supports the controls and components 6, 7 with their operative mechanism exposed for access, and which runs transversely of the oooker cabinet, communicating with the cavity between the two skins of the cabinet on the opposite side of the cooker to that containing the duct 8.
  • the exit aperture constrains or assists the air to flow laterally away from the cooker so as to minimise draughts of warm air.
  • These draughts can be particularly annoying if they occur at waist level, and the combination of a diffusive output path, via the two skins of the cabinet as a whole, rather than a defined duet, the low-level exit aperture and the general transverse movement, away from the cooker, of exiting air combine to minimise such draughts.
  • the duct In order to ensure that cooling efficiency is not greatly reduced by the air in duct 8 being heated as it flows past either of the compartments 3 or 4, it is desirable for the duct to be either lined with, or formed of, thermally insulative material, at least where it runs adjacent said compartments. As an alternative, which may be preferred with some cooker constructions, thermally insulative material may be interposed between the walls of the compartments 3 and 4 and the inner wall of the duct 8.
  • the walls of compartments 3 and 4 are, of course, usually insulated in any case, and in some circumstances it may be unnecessary to provide further insulation for the duct 8.
  • the air used for the aforementioned purposes prefferably be filtered before it encounters the fan 10 or, at least, the controls and components 6, 7 which it is desired to cool. This avoids the undesirable deposition of dust, fluff and similar materials in the passageways of the air management system or upon the controls or components themselves.
  • a filter such as that shown at" 12 is provided at the inlet aperture 9 to the duct 8.
  • controls and components 6, 7 are so sited that components, such as the timer/processor unit 7, which may be particularly sensitive to exposure to excessive temperatures, are located closer to the fan than are the other controls, thus ensuring that these particularly sensitive components are exposed to the coolest air, i.e. that which has not passed other controls or components but which has only been drawn through the duct 8.
