Other embodiments of the invention and many of the attendant advantages of the invention will be readily appreciated as they become better understood with reference to the following detailed description.
DESCRIPTION OF PREFERRED EMBODIMENTS
[0041] With reference firstly to
[0042] As best seen in drawing
[0043] The inner shell 12 of the body 10 has the form of a tub or basin and is housed within and is spaced from the outer shell 11 such that the exterior of the cooker 100 is thermally isolated or insulated from the fuel chamber 13. In particular, the tub-like inner shell 12 is supported within the outer shell 11 along an upper peripheral rim or edge 18 thereof and around a periphery 18 of its base so that at least about 95 percent of an outer surface area of the inner shell 12 is spaced from outer shell 11. In this way, a gap G of at least about 10 mm is provided between the inner shell 12 and the outer shell 11 by the spaced arrangement and this gap may optionally be at least partially filled with a suitable thermal insulation material rated to temperatures in the range of 200 C. to 500 C. As a result, the outer shell 11 is thermally isolated or insulated from the fuel chamber 13, such that a user may touch the outer shell 11 when the cooker 100 is in normal use without the risk of a severe burn. This is highly desirable for protecting the user and children during use of the cooker 100. The outer shell 11 is typically comprised of metal and may be formed from sheet metal or may be die cast. Similarly, the inner shell 12 and the fuel bucket 14 are also typically comprised of metal and are preferably formed from sheet metal. Examples of suitable metals for the outer shell 11, the inner shell 12, and the basin or bucket 14 include both aluminium and steel, although aluminium is preferred for its relatively low density; i.e. as a light-weight material.
[0044] As is apparent from
[0045] The cooker 100 includes an electric ignition system 20 in the body 10 for igniting solid fuel supported in the fuel chamber. The electric ignition system 20 includes at least one electric heating element 21 which is mounted within the inner shell 12 and located in or adjacent the fuel chamber 13 just below and/or in contact with the solid fuel basin or bucket 14 for heating and igniting the solid fuel supported therein. This ignition system 20 is described in detail in the co-pending Australian Patent Application No. 2017232161 entitled Cooker with ignition system for solid fuel, the contents of which are incorporated herein by reference. For this reason, the various features and operation of this ignition system 20 will not be explained here in detail. It will be noted, however, that the ignition system 20 typically comprises an electric cable 91 for connection to an electrical power supply socket to supply electrical energy to the heating element 21 of the ignition system. The electric cable 91 is wound on a spool 92, which is mounted in a recess 24 below the fuel chamber 13 in the space between the inner shell 12 and the outer shell 11. Heat shielding 25 is preferably provided around the recess 24 to prevent heat damage to the cable during use of the cooker. The cable spool typically has a torsional bias for retracting the cable such that an electrical plug 93 of the cable resides within a recess 26 formed in the bottom of the outer shell 11 of the body 10 when not in use. A latch mechanism such as a pawl and ratchet allows for unwinding of the cable whilst holding against the torsional bias to prevent retraction of the cable upon release. The latch mechanism includes a user operated release actuator for disengaging the latch to allow the torsional bias to effect cable retraction. In one form the user operated release actuator is a button connected to the latch to enable disengagement thereof. Alternatively, the user operated release actuator may be incorporated into the latch mechanism and spool such that disengagement of the latch may be accomplished with a further short pull of the cable.
[0046] The cooker 100 further comprises an electronic control system 90 for controlling and/or monitoring operation of the cooker. This control system 90 is operatively connected to the ignition system 20 and configured to deactivate the electric heating element 21 after a predetermined period of time has elapsed following its activation, and/or if the temperature exceeds a predetermined threshold, in order to avoid over-heating and unnecessary power consumption. The predetermined period of time is typically in the range of about 5 minutes to about 10 minutes. The cooker 100 will typically include one or more temperature sensors as shown in
[0047] Referring further to
[0048] As can be seen in
[0049] Referring again to drawing
[0050] In one embodiment, the chimney assembly includes a grease filter to filter gases rising through the cooker and exiting the outlet vents. The filter also prevents the outlet from becoming clogged with fat/oils residue. The filter is a mesh type baffle filter and may be formed of for instance, metal such as aluminum and/or carbon or charcoal. Suitably the filter is removable for replacement and/or cleaning.
[0051] As can be seen in
[0052] With reference to drawing
[0053] Referring now to
[0054] Instead of a toggle latch 37, the cooker 100 shown in
[0055] With reference to
[0056] With reference to
[0057] In this embodiment, temperature sensors 87a and 87b are incorporated or fixed in the hood 30 for sensing the temperature at different locations in the cooking zone 16. The sensors are operatively associated with the control system, which calculates an average or weighted average temperature and conveys it to the user via the display device or wireless connection.
[0058] As seen in
[0059] One or more connection ports 111 are provided within the cooking zone, for receiving the plug 98 of the probe 95 and interfacing with the control system. As can be seen with reference to
[0060] Furthermore, the handle 36 and latch mechanism 80 are constructed to allow lifting and repositioning of the cooker. With the hood 30 closed and the latch mechanism in the latched state, the handle 36 may be used to lift the cooker. Suitably, the rear of the cooker includes a rear lifting formation 36b or handle so that the cooker may be lifted from front and rear co-operatively. As shown in
