Introduction

Air fryers are new kitchen appliances that are just becoming popular. The primary function of these appliances is to circulate hot air using rapid air technology. They work using a mechanical fan to circulate the air. As a result of this fast circulation around the food, the food is fried. The best part of this machine is that it generally uses %80 less oil to fry the food. It takes a different amount of time to fry different types of food.

Disassembly

The disassembly part was challenging as well as entertaining. We worked successfully as a team, we distributed the tasks equally.

Part Comparisons and NX Commands

This was a challenging part for me. It is a small part in real life and there are smaller details on it, so a ruler or caliper could not help me. I used a needle and tried to be precise as well as I could. After that, I started by drawing the middle part. I used the revolve command for some details. Then, I drew the top and mirrored it because it is symmetrical. I also learned a new command ‘text’. I needed it because there are some letters and numbers that I need to put. The rest of the drawing consists of indentations and protrusions.

Drafting and Tolerances

While making the draft, it was not possible to give the dimensions of the small protrusions behind the cover using only the orthogonal view.

Finite Element Analysis

Because the working principle of our machine is to get hot and cook the food, the analysis we should make was thermal (heat) analysis. The numbers we decided that are sufficient are 159.143 for the elements and 308.621 for the nodes. Then, we heated the base of the receptacle up to a certain degree. After the analysis, we made inferences about which places on the receptacle warm up first, and how much heat flow happens. Consequently, the outer surface of the receptacle warms up slowly and less so it is generally safe to touch. However, the upper edges are almost at the same temperature as the base, so it is not safe.
