Detailed Implementation
[0038] Referring now to the accompanying drawings, a vent cap 1 for a cooking appliance 10 can be seen. The vent cap 1 includes a base 2 having an opening 20, an attachment member 3 hanging from the base 2 and surrounding the opening 20, and a frame 4 protruding from the base 2 and surrounding the opening 20.
[0039] The base 2 is square and includes a circular groove 5 on its lower surface 21, which surrounds the attachment member 3. The groove 5 is designed to receive an O-ring (not shown) to ensure a seal between the vent cap 1 and the cooking appliance 10.
[0040] The base 2 also includes a circular inner wall 6 projecting from its top surface 22, which surrounds the attachment member 3. The circular inner wall 6 is located radially between the attachment member 3 and the groove 5. The circular inner wall 6 forms an annular recess 60 around the opening 20 of the base 2.
[0041] The attachment 3 includes a bayonet connector 30 with multiple connecting elements 31, 32 (six in this example). The connecting elements 31, 32 are equidistantly spaced around the edge of the opening 20 and include five spaced legs 31 and anti-misalignment components 32 to ensure proper installation on the cooking appliance 10.
[0042] Each outrigger 31 includes a tapered inlet 31a at one end and a fastening ramp 31b. The anti-misalignment component 32 is similar in shape to each outrigger 31, but has a spring-loaded arm 33 and a protrusion 34 at its free end, which replaces the tapered inlet 31a.
[0043] The attachment member 3 also includes a ring 35 extending from the base 2 and surrounding the opening 20. The legs 31 and the anti-misalignment member 32 both project radially outward from the ring 35, such that they are spaced apart from the base 2 to form a gap.
[0044] The frame 4 includes an outer peripheral wall 40 characterized by discontinuities 41 in the form of inlets 41a, 41b, 41c, and 41d within the outer peripheral wall 40, for ensuring airflow through the vent 11. The outer peripheral wall 40 also includes a sloping top edge 42 to prevent objects from being placed on the frame 4, and a slot 43 for draining water. The lower end of the outer peripheral wall 40 flares outward to form a skirt 44 around its edge.
[0045] The cooking appliance 10 includes one or more vent pipes 11 and a break ring (not shown) having holes around the vent pipes 11. Each hole (not shown) in the top portion of the cooking appliance 10 has a shape substantially corresponding to one of the legs 31 or a fall prevention component 32.
[0046] In use, the vent cap 1 is lowered onto the top of the cooking appliance 10, such that the frame 4 surrounds the vent 11. To attach the vent cap 1 to the cooking appliance 10, each support leg 31 and anti-misalignment component 32 is inserted into the corresponding hole. The orientation of the tapered inlet 31a and the fastening ramp 31b allows the vent cap 1 to rotate to engage, capture, and gradually compress the edge of the hole.
[0047] Additionally, the spring-loaded arm 33 of the anti-misalignment component 32 elastically deforms until the protrusion 34 aligns with a cavity or hole in the cooking appliance, and then the protrusion snaps into place to releasably attach the vent cap 1 to the cooking appliance 10.
[0048] Those skilled in the art will recognize that several variations of the foregoing embodiments can be conceived without departing from the scope of the invention.
