AI Technical Summary

Benefits of technology

[0008] The invention disclosed herein includes the realization that control knobs for cooking appliances can be improved and production cost reduced by having a control knob assembly comprising a knob housing, a gripping portion, and a control valve interface portion, wherein the control valve interface portion is positionable in any one of a plurality of positions relative to the knob housing, and wherein the control valve interface portion is configured to be coupled to the gripping portion. It is further recognized that cooking appliances having an overlapping control knob and bezel assembly can provide increased protection of the control knob for, and can lend enhanced appearance to, the cooking appliance.

Problems solved by technology

Control knobs having integrally formed metal cores can be difficult to manufacture and a plurality of such knobs with cores of differing orientations need to be manufactured.
Forming and machining the control knobs in this manner is difficult, time consuming, and expensive.
However, a different mold or process is needed to form each desired orientation of the control knob, which also adds significant costs.
While the insert arrangement allows for a standard control knob housing and can provide an opening having the desired orientation, the manufacturing and assembly costs and challenges associated with this type of control knob are also high.
