DESCRIPTION OF EMBODIMENTS

[0078] Referring to FIG. 1, there is shown an installed exhaust canopy, generally designated 10, in accordance with a first form of the invention. The exhaust canopy is adapted to receive and disperse an exhaust, the exhaust comprising exhaust air, wherein the exhaust air includes smoke, odour and/or grease and the exhaust air is heated above room temperature. The exhaust canopy is configured to extract exhaust air originating from a space comprising cooking equipment when such cooking equipment is in use. The exhaust canopy 10 is mounted at its rear to a vertical wall 11, and overhangs a stove top 12 of a stove cooker 13 and a gas top 14 of a gas cooker 15. At the rear of the exhaust canopy is located a control unit 17 having up and down buttons, 21 and 22 respectively, for configurational adjustment of the canopy 10. A person 16 is shown standing in front of the stove and gas cookers, 13 and 15 respectively. The exhaust canopy 10 is shown in a resting or use configuration, as is required for capturing heat, smoke, odour or grease emitted from foods being cooked on the stove and gas tops, 12 and 14 respectively.

[0079] FIG. 2 also shows the installed exhaust canopy 10 in the use configuration. From this view can be seen parts of the canopy 10 including a fixed or stationary portion 18, an adjustable or mobile exhaust portion 19, and an adjustment mechanism 20 for continuously adjusting the exhaust portion 19 between the use configuration and an open or cleaning configuration. As can be seen, the exhaust portion 19 of the canopy is stowed within the fixed portion 18 when in the use configuration.

[0080] On reaching up to the control unit 17 and pressing the down button 22, the person 16 is able to lower the exhaust portion 19 of the canopy 10 from within the fixed portion 18, as can be seen in FIG. 3, with the canopy shown in an intermediate or partially lowered or open configuration. The exhaust portion 19 can be further lowered until the canopy 10 reaches the cleaning configuration as shown in FIG. 4. Once the canopy 10 reaches the cleaning configuration, the exhaust portion 19 is within arm's reach allowing the person 16 to wipe clean its internal aspects, and remove a grease filter housed within for cleaning or replacement.

[0081] Referring now to FIGS. 5 and 6, there is shown a frame, generally designated 23, of the exhaust canopy 10. The frame 23 is shown in the open cleaning configuration in FIG. 5 and the closed use configuration in FIG. 6.

[0088] The exhaust section 25 of the frame 23 has three planar left sided members in the form of a first left rod 36a, a second left rod 37a, and a third left rod 38a. The first and second left rods, 36a and 37a, are of similar length, whereas the third left rod 38a is about two thirds of their lengths. The left sided members are connected end to end to form a left triangular frame section.

[0089] Similarly, the exhaust section 25 of the frame 23 has three planar right sided members in the form of a first right rod 36b, a second right rod, 37b and a third right rod 38b. The first and second right rods, 36b and 37b, are of similar length, whereas the third right rod 38b is about two thirds of their lengths. The right sided members are connected end to end to form a right triangular frame section.

[0090] Additionally, the exhaust section 25 of the frame 23 has three parallel horizontal members in the form of a first horizontal rod 33, a second horizontal rod 34, and a third horizontal rod 35. The first horizontal rod 33 is connected with and extends between joined ends of the first and second rods, 36a/37a and 36b/37b. The second horizontal rod 34 is connected with and extends between joined ends of the first and third rods, 36a/38a and 36b/38b. The third horizontal rod 35 is connected with and extends between joined ends of the second and third rods, 37a/38a and 37b/38b.

[0091] The adjustment mechanism 20 comprises left and right vertical plates, 39a and 39b respectively. The left vertical plate 39a is planar with and attaches above to the left top horizontal side rod 28a and behind to the left front vertical rod 30a. Similarly, the right vertical plate 39b is planar with and attaches above to the right top horizontal side rod 28b and behind to the right front vertical rod 30b.

[0092] The adjustment mechanism 20 further comprises upper left and right adjustment arms, 40a and 40b respectively, and lower left and right adjustment arms, 41a and 41b respectively. The upper left adjustment arm 40a is pivotally or rotatably attached at one end to the left first rod 36a and at its other end to the left vertical plate 39a. Similarly, the upper right adjustment arm 40b is pivotally or rotatably attached at one end to the right first rod 36b and at its other end to the right vertical plate 39a. The lower left adjustment arm 41a is pivotally or rotatably attached at one end at the junction of the left first rod 36a and the left second rod 37a, and at its other end to the left vertical plate 39a. Similarly, the lower right adjustment arm 41b is pivotally or rotatably attached at one end at the junction of the right first rod 36b and the right second rod 37b, and at its other end to the right vertical plate 39b.

[0093] Also present as part of the adjustment mechanism 20 are left and right electric linear actuators, 42a and 42b respectively. Each actuator 42a/42b comprises a housing unit 46a/46b, telescopic adjustment means having an outer tubular member 43a/43b and an inner tubular member 44a/44b, and an attachment bracket 45a/45b which is pivotally connected with its respective inner tubular member 44a/44b.
