Abstract
A floor standing electric cooker is provided comprising a casing (21, 29), a hob (10), an upper oven (12) and a lower fan oven (14) housed in an oven space of the casing above a plinth (16). Convective cooling air (27) enters the plinth (16) and a first part flows through openings (25) in floor (24) through the oven space, discharging through hob opening (33). A second part (30) flows from the rear of the plinth (16) up wall (29). When the lower oven (14) is in use cooling fan (37) coaxial with oven fan (36) provides a forced flow of cool outside air into the oven space. Air is ducted by cover (41) past terminals (40) to fan inlet (38) whereby the terminals (40) are kept cool when the lower oven (14) is on. Despite the compactness of the cooker, the cooling of sidewalls (21) is sufficiently effective for them to butt against kitchen units without an air gap. <IMAGE>

SPECIFICATION
Improvements in or relating to cookers This invention relates to a floor standing cooker.
In conventional twin oven floor standing cookers it has been necessary to leave a space between the sides of the cooker and adjoining kitchen units, otherwise unacceptably high temperatures can result. The Belling Format Cook Centre overcomes this problem on a 600 mm by 600 mm plan by providing a cooling fan within the casing adjacent the hob, and it is an object of the invention to provide a simpler way of cooling a cooker casing but which is effective even in a cooker built on a 500 mm by 500 mm plan.
Broadly stated the invention provides a cooker comprising a hob, an upper oven and a lower oven housed in a casing having an air inlet and an air outlet to free space around the ovens, wherein on operation of the lower oven a fan in the free space creates a through flow of cooling air from the inlet to the outlet.
In a further aspect the invention provides a cooker having a floorstanding casing, and upper and lower ovens mounted in the casing, wherein the casing includes a rear panel and a front frame formed with apertures conforming to the fronts of the upper and lower ovens, and each oven is provided with brackets which locate in straps extending between the rear panel and the front frame to hold the oven in position against the front frame.
An embodiment of the invention wil; now be described by way of example only with reference to the accompanying drawings, in which:
Figure 1 is a rear perspective view of a cooker according to the invention; and Figure 2 is a rear perspective view of the cooker during assembly showing how the ovens are fixed in place.
In Figure 1, a cooker that is of width and breadth 500 mm and of overall height 850 mm or 900 mm comprises a casing in which are fitted a hob unit 10, an upper grill oven 12 of smaller size and a lower fan oven 14 of larger size. The casing of the cooker defines a plinth 16 formed by lower front and rear panels 18, 19, removable lower side panels 20 and the lower parts of side panels 2 1. The lower front and rear panels are formed with limbs 22, 23 of dissimilar length, either of which is attachable in the upright position. For the 900 mm overall casing height the panels 18, 19 are fitted with their longer limbs vertical and with the lower side panels 20 in place. For the 850 mm overall casing height the panels 18, 19 are fitted with their shorter sides vertical and with the lower side panels 20 removed. Thereby two possible working heights for the hob unit 10 are provided which can be changed over when the cooker is fitted in the home using only simple tools.
Above the plinth is a floor plate 24 formed with side cut-outs 25 defining air inlets. The front panel 19 defines with the plate 24 an opening defining a front air inlet 26 to the space beneath the floor 21 as indicated by - arrows 27 and the rear panel 18 defines with the plate 24 an opening 28 through which the predominant air flow is a small upward current over back panel 29 as indicated by arrow 30.
The ovens 12, 14 are surrounded by insulation generally indicated by the reference 31, but the insulation does not touch side panels 21 or the underside of the hob unit 10 so that there is a free space within the casing for air circulation. When the top oven 12 is in use there is a convective air flow through the inlets 25, up the sides of the cooker as indicated by the arrows 32 and out through a rear vent or chimney 33 as indicated by arrows 34. There is also a convective flow between the panel 29 and the insulation 31 that discharges through top rear vents 34 in the panel 29. But when the lower oven 14 is in use a forced air flow is required if the external surfaces and controls are to be maintained at sufficiently low working temperatures. The oven 14 has an air circulation fan 36 driven by a motor 35, and the shaft that carries the fan 36 also carries a second fan 37 in the free space. The fan 37 acts as a centrifugal impeller with an air inlet defined by aperture 38 in panel 29 through which air is drawn from outside the casing and discharged into the free space. A cover plate 42 fits on the panel 29 over the motor 35 and slot 38 and also extends downwards to cover terminals 40 for attachment of a power supply cable with its open lower end 42 beneath the open- ing 28. By this means the terminals 40 are in a cool air stream whenever the oven 14 is operating, the air for the fan 39 enters partly direct through the slot between lower end 41 and lower rear panel 18 as indicated by arrow 43 and partly from underneath the cooker through opening 28 as indicated by arrow 44.
Between the hob 10 and the top oven 12 at the front of the cooker there is fitted a control chamber 45 defined by wall 46 which closes off the front of the cooker. Controls 47 on a control panel 48 are provided in the chamber 45, the panel 48 being rearwardly inclined to improve control visibility. As will be noted the grill oven 12 has a roof that slopes rearwardly and upwardly to an exhaust duct or chimney 49 which opens to the rear of the cooker above the hob 10 and is located just behind the chimney 33 with which it shares a common mouth. Thus when a grill heating element in the oven 12 is on there is a flow of hot air towards the rear of the oven 12 and up the chimney 49 as described in our copending U.K. Patent application No. 8319572. For further cooling of the control chamber 45 chimneys 50 at the sides of the 2 GB2164142A 2 cooker adjacent the front frame thereof feed air from adjacent the plinth into the chamber 45, the air being discharged through a slot between the upper part of wall 46 and the hob 10.
Figure 2 shows the way in which the ovens 12, 14 are mounted. The front of the cooker is formed with a frame 60 formed with in wardly flanged apertures for the upper and lower ovens. Each oven is flanged at its front to locate behind the flanged apertures in the frame 60, a silicone rubber gasket (not shown) being provided between the oven flange and the front frame. To either side each oven is provided with welded on brack ets formed with projecting tags 62 that en gage slots in straps 63 of shallow channel section that are attached to the front frame to hold the ovens in place. The rear ends 64 of the straps are attached to back panel 29. This arrangement has the advantages that:
(a) the cooker has an easily assembled but rigid frame structure; (b) the insulation 31 is held in place behind the straps 63 which assist in maintaining the 90 free space for air circulation; and (c) the straps 63 can be used to anchor door mechanisms and in particular springs for a bottom-hinged door to the top oven 12.
