A kitchen appliance is a device designed to assist in food preparation and cooking. Common examples include refrigerators, microwaves, ovens, and blenders. These appliances can be powered by electricity, gas, or batteries, and they help streamline various tasks, making cooking more efficient and convenient. Many kitchen appliances come in different sizes and styles to fit various kitchen designs and personal preferences. Some appliances, like toasters and coffee makers, are small and portable, while others, like dishwashers and stoves, are larger and often built into the kitchen layout.
