standard household ovens typically have a door located at the front, not at the bottom. The door is positioned at the front of the oven to allow easy access to the oven cavity for placing or removing food and to ensure safety during operation.
However, there are some specialized types of ovens, such as drop-door ovens, where the door is positioned at the bottom. These ovens are commonly found in commercial kitchens or professional baking environments. The main reason for the bottom-positioned door is to facilitate loading and unloading large quantities of items efficiently.
In a drop-door oven, you can slide out a rack or platform from the bottom of the oven, and the door itself is essentially part of this sliding mechanism. This design is helpful when dealing with heavy or bulky items that would be challenging to lift up and place on a rack from the top. Additionally, drop-door ovens are often used in bakeries, where bakers need to load and unload multiple trays of baked goods quickly.
Again, it's essential to note that standard household ovens don't typically have doors at the bottom, and their doors are located at the front for ease of use and safety reasons. If there have been any significant changes or developments in oven design , I would not be aware of them.
