Everyday we use some sort of cooking appliance or tool to prepare our foods. Whether it’s microwaving your favorite frozen pizza or toasting a breakfast pastry, cooking appliances provide some of the greatest conveniences known to man. However, did you know that many of the appliances that we use today were protected by patents at one point in time? In this week’s blog post, we will be discussing what appliances or cooking instruments have been patented.
The Air Fryer
Ah yes, the air fryer. It can make some of the crispiest french fries you ever tasted without requiring gallons of oil to fry. However, some earlier air fryers were patented. U.S. patent no. 4,817,509 (“‘509 patent”) discloses one of the earlier types of air fryers. The ‘509 patent discloses an air fryer invention designed to cook foods with less oil. The invention is also designed to solve issues such as “brown foods” more efficiently. More specifically, the air fryer disclosed in the ‘509 patent “provides very rapid cooking, develops browning and flavoring of the cooked product, and will provide products similar to those typically deep fat fried but with controlled oil content.” It’s pretty cool that these concepts were thought of so early on and were later patented.

The microwave is probably an appliance that every household has. The microwave has become one of the most widely used appliances to date. One of the earlier versions of the microwave was patented under U.S. patent no. 2,704,802 (“‘802 patent”). The ‘802 patent discloses invention for a “microwave oven and, more particularly, relates to a broadside transition for coupling microwave energy from a wave guide into an oven whose dimensions are large compared with the wave length of said energy.” Pretty neat way of describing a microwave, huh?

Now we are going to travel far back in time, way back to the 1920s. We are going to look at U.S. patent no. 1,394,450 (“‘450 patent”) that covers an early version of the toaster. The toaster disclosed in the ‘450 patent looks quite different from the modern toaster, as seen below. However, it seems that the toaster covered by the ‘450 patent can still toast bread pretty well, from a speculative standpoint.
