Product Description

We dissected a 6-slice toaster oven made by Oster, Model#TSSTTVXLDG. It has two heating elements on the top and bottom walls of the oven. It is a 120V, 1500W oven. It also has a fan that circulates the heat within the oven. This enables the heat to spread evenly all around the cooking area so the food retains it original flavor. It has a glass door that opens out and is held in place with a spring, so you have easy access to the food.

How It Works

The electricity comes into the control panel where the power is adjusted for strength and time based on input by the user. The electricity is sent through two heating elements at the top and bottom of the unit while a fan is powered to circulate the hot air around the food in the oven to allow for even cooking. The unit has an inner and outer shell, inner holds the actual cooking elements and food, while the second shell creates an air barrier which allows the toaster to cool and not transfer the heat to its outside surroundings.

Comparison to Toaster

The toaster oven is very similar to a toaster. The 6-slice toaster oven is about four times the size of the average 2-slice toaster. The toaster oven has larger versions of the heating elements that are inside a toaster. In the toaster, the heating elements lie on the side walls in each toasting compartment. While the toaster oven has larger heating elements on the top and bottom of the inside. The toaster oven has double the wattage (1500W) than the toaster (750W). The toaster oven is capable of cooking more of a variety of foods than the toaster because of its size and the placement of the food. Overall, the toaster oven is a cross between a toaster and a conventional oven. It works similarly to a toaster, but has similar cooking capabilities to the oven.
