Description

A HEATING AND COOKING APPARATUS

Field of the Invention

The present invention relates to a combined heating and cooking apparatus. In particular, the present invention relates to a combined heating and cooking outdoor apparatus.

The first channel comprises a first channel inlet 18 configured to be in communication with the outlet 8 of the stove 4, and a first channel outlet 20. In the illustrated embodiment, the first oven 10 (and the first inner and outer chambers 12 and 14) are substantially cuboid in shape. It is however to be understood that each of the first oven, inner chamber 12 and outer chamber 14 may have any suitable shape and/or dimensions depending on the requirements for the apparatus 2.

The apparatus 2 further comprises a second oven 22 comprising a second inner chamber 24 configured to receive items to be heated, and a second outer chamber 26 substantially surrounding and spaced apart from the second inner chamber 24 to provide a second channel 28 extending therebetween. The second channel 28 comprises a channel inlet 30 configured to be in communication with the channel outlet 20 of the first oven 10, and a second channel outlet 32.

The first oven 10 is located above the outlet 8 of the stove 4. The second oven 22 is located above the first oven 10.

The apparatus 2 further comprises a chimney 34 configured to be in communication with the second channel outlet 32 of the second oven 22 to enable heat and/or hot air to pass therethrough.

The apparatus 2 further comprises a hot air passageway 36 comprising a first end 38 located at or adjacent one or more of: the second channel outlet 32 and/or chimney 34. The hot air passageway 36 comprises an opposed second end 40 in communication with a filter configured to remove particulates to enable clean hot air to pass therethrough to an external environment.

The apparatus 2 further comprises a valve or lever located at or adjacent the first end 38 of the hot air passageway 36. The valve or lever is moveable between a first closed position in which heat and/or hot air from the fuel source is passed through the chimney 34, and a second open position in which heat and/or hot air from the fuel source is passed through the hot air passageway 36 and through filter.

The hot air passageway 36 is an adjustable directional hot air passageway. The position of the opposed second end 40 of the passageway 36 may be adjusted relative to the first end 38 thereof.

Each of the first and second inner chambers 12, 24 of the first and second ovens 10, 22 further comprises a plurality of racks 46 for supporting items thereon. Each rack 46 is slideably mounted within the respective first and second inner chambers 12, 24.

Each of the first and second ovens 10, 22 further comprises a door 48, 50 moveable between a first closed position in which the first and second inner chambers 12, 24 are substantially sealed from an external environment, and a second open position in which access is provided to the first and second inner chambers 12, 24.

Each door 48, 50 is hingeably connected to the corresponding first and second outer 14, 26 and/or inner 12, 24 chambers of the first and second ovens 10, 22. The or each rack 46 is configured to be slideably moveable relative to the corresponding first and second inner chamber 12, 24 on movement of the door 48, 50 between the first closed position and the second open position.

The first oven 10 further comprises a water inlet 52, at least one water outlet 54, and a water passageway extending therebetween. The water passageway is configured to receive heat and/or hot air from the outlet 8 of the stove 4.

The first oven 10 further comprises a temperature gauge 56 for determining the temperature of the first inner chamber 12. The temperature within the first inner chamber 12 of the first oven is more than the temperature within the second inner chamber 24 of the second oven 22.

The apparatus 2 further comprises a spillage tray 58 for receiving items of spilled food or liquid therein.

In use, fuel is burnt within the cavity 6 of the stove 4. Hot air rises out of outlet 8 of the stove 4 and the heat is spread evenly by heat spreader 9. The hot air rises through inlet 18 of the first channel 16 of the first oven 10, thereby heating the inner chamber to a temperature suitable for cooking food. Hot air passes through the first channel and out of outlet 20 into the inlet 30 of the second channel 28 of the second oven 22. The heat raises the temperature within the second inner chamber 24 of the second oven to a temperature suitable for keeping food warm or for drying items. Hot air exits outlet 32 of the second oven 22 and passes into the chimney 34 or the hot air passageway 36 and out of filter to produce heat for the external environment.

The invention has been described by way of examples only and it will be appreciated that variation may be made to the above-mentioned embodiments without departing from the scope of invention as defined by the claims, in particular but not solely 5 combination of features of described embodiments.
