Before submitting a new icon request, please confirm the following:

• [X] I have searched all issues to make sure there isn't a request for this icon.
• [X] I have searched the current library to make sure the icon doesn't already exist.
• [X] I understand that brand icons are no longer being added and I can use SimpleIcons for my brand icon needs.
• [X] I only intend to request a single icon (or a few near-identical ones) in this issue.

What would you use this icon for?

Hi, Would like to request 2 icons showing preheating conditions for ovens

1. For top/button oven heating (or upper/lower heating)
2. One for HotAir oven heating

Give us an example of what this icon might look like.

I would also like an oven icon. I quite like the oven icon @GreenTurtwig in https://github.com/Templarian/MaterialDesign/issues/5592#issuecomment-717315694 because it matches the stove and similar to the existing toaster-oven icon.

It would be helpful if mdi:stove had its companion mdi:stove-off, which is available for dishwasher, washing-machine and tumble-dryer.
