Actually closer to a sub category called impingement ovens.

Wikipedia:

Another form of a convection oven is called an impingement oven. This type of oven is often used to cook pizzas and lightly toast bread in restaurants, but it can also be used for other foods. Impingement ovens have a high flow rate of hot air from both above and below the food. The air flow is directed onto food that usually passes through the oven on a conveyor belt.
