Abstract: A domestic cooker has a plenum chamber positioned to the rear of its oven cavity. Air is pump into the chamber by a fan which draws air around the outside of the cavity. Air exits from the chamber to atmosphere via a duct above the oven cavity having first passed over the cooker control panel to keep the latter at an acceptable temperature. The oven cavity has a door of a composite construction with inner and outer door panels spaced apart by a passageway open at the top and at the bottom of the door. Air from the plenum chamber flows to the passageway via a second duct located beneath the cavity. In another embodiment of the invention the cooker has two oven cavities each with a door of the composite construction, the passageways between the inner and outer panels of each door being supplied with air from a plenum chamber at the rear of the cavities.

Abstract: An air extractor arrangement is adapted to be flush fitted in a kitchen work-top 4 and which comprises a fixed housing 1 which is coupled to an extractor fan 8, and a pop-out section 10 which is telescopically disposed within the housing 1, a linear bearing in the form of a slide bar assembly 12,13 being provided between the housing 1 and the pop-out section 10 by means of which the pop-out section 10 is supported in the housing 1. Arrangements are described for driving the pop-out section 10 either semi-automatically or fully automatically.

Abstract: A gas tap for a gas cooker or hob includes a rotary disc valve (20) which controls the flow of gas from a gas rail (1) to a gas burner of the cooker or hob. To simplify the tap construction and facilitate manufacture, an external surface (2) of the gas rail (1) is used to form part of the tap housing and to provide the seating surface for the disc valve (20).

Abstract: A hob with a spillage tray (2), gas burners (16) and a member (30) secured to an undersurface of the spillage tray, gas taps (12) being accommodated between the member (3) and the spillage tray (2). The member (30) also forms, with the spillage tray (2), a respective fuel supply passage (33, 34, 35) for carrying fuel to each respective burner from the associated tap. The member (30) can be sealed, or sealed and secured, to the spillage tray by an adhesive. The hob may have electric heating units instead of, or in addition to, gas burners.

Abstract: A shelf unit (3, FIG. 1) for a refrigerator cabinet includes an air flow passageway (6) connectible to a duct (1) located at the rear of the refrigerator. The flow of air through the passageway (6) is regulated by a flap whose movement is controlled by a thermostat (9) also mounted upon the shelf. The shelf unit, when in position in a refrigerator, enables a user to preset the temperature of the zone in the refrigerator cabinet beneath the unit.

Abstract: A gas hob comprises a spillage tray (8) apertured to receive gas burner heads (18) supplied with gaseous fuel via passages formed between the spillage tray and a plate (32) secured to the undersurface of the tray by a suitable adhesive. The plate is preferably of an organic material based on hydraulic cement examples of which are described in European Patent Applications Nos. 80.301909.0 (0 021 682) and 81.301228.3 (0 038 126).
