Purpose of hole in stove leading to oven

Question

I'm staying in a hotel and have access to a "electric coil stove" for one of the first times.

I accidentally turned on the oven light and saw that the light was shining up through only one of the stoves:

There's only a port from the oven into the top right stove, and note that the stove is not on.

Here's a view from within the oven:

Is there a hole here as a vent for the oven for some reason, or is this for the stove? I typically use a glass "flat-top stove" that doesn't have an oven underneath it. I've never seen a direct hole from a stove to the oven before, and have to wonder what the purpose is.

Answer 1

A simple Google search yielded the following

All ovens are vented one way or another. You would not want to heat up the air in a sealed chamber because of thermal expansion. It would explode due to the heat expanding because it has no way to vent. A vent is also needed to vent fumes and by products that burn off during the self cleaning process.

A vent is necessary and should not be blocked

Answer 2

The vent is there to prevent stratification. In other words, to ensure the oven is heated evenly throughout. It causes a lot of issues, however, for people who are cooking more difficult fares (including those particularly sensitive to humidity).

Answer 3

I assume it is to help with air flow. Heat the same air over and over again and it gets stale. It also lets the wonderful smells waft about the household.
