2. Common Kitchen Appliances  Refrigerators  Ranges  Microwaves  Cook-tops  Dishwashers

3. Refrigerators  Come in many designs and styles: Side by side-refrigerator on one side, freezer on other. Pull out freezer drawer on bottom. French Door Freezer on top, refrigerator on bottom Under counter types

4. Ranges (a.k.a. stoves) - Cooking Features  Bake Systems Conventional cooking Convection cooking  Heat Source Gas burners Electric heating elements Ceramic cooking top What is the right choice for you?

5. Bake Systems – Conventional cooking  Uses heated air to cook food  Hot air rises in the oven leading to hotter area in parts of oven  Also known as “standard” or “thermal” stoves Weakness:  Can be difficult for air to circulate and cook food evenly  Over crowding does not allow heated air to cook food evenly

6. Bake Systems – Convection cooking  Utilizes a fan that circulates the heated air.  Quicker and more even distribution of heat Food cooks faster More food can be cooked at once Quicker cooking allows food to retain more nutrients  Available in both gas and electric ovens.

7. Gas Heat  Affords extreme control of heat levels Visible flame allows greater control Heat extinguished instantly upon shut-off  Available in sealed or conventional burners  Pilot or electronic- ignition system

8. Electric Elements  Coil – least expensive heating system. Reliable & easy to replace Slow to cool down  Radiant elements – most common in smooth tops Elements installed beneath glass-ceramic surface Indicator lights – hot surface Easy to clean up

9. “Ranges” - Types  Freestanding Range  Slide-In Range  Drop-In Range  Cooktops  Wall (or Built-In) Ovens

10. Freestanding Range  Includes a cooktop and oven  Size: 20-40 inches wide (30 inches most common)  Comes in gas and electric power sources  Least expensive and most popular styles.

11. Slide-In Range  Includes a cooktop and oven  Generally has a storage drawer at bottom  Provides a more custom look.  Designed to fit 30 inch openings between cabinets.  Eliminates the back console.  Meets the countertop

14. Wall (or Built-In) Ovens  Uses gas or electric heat  Include one or more ovens in a single appliance  Does not include a cooktop  Can include combination of thermal and convection heat  Can be installed in walls or kitchen cabinets

15. About MICROWAVE OVENS  Very energy efficient. it takes 18 times as much energy to bake a potato in a regular oven as in a microwave.  Cook food faster heat the food, not the oven or the containers.  Heat food through friction 1. Microwaves bounce off food molecules. 2. Food molecules vibrate from the impact. 3. The rapid vibrations create friction, which produces heat. 4. The heat cooks the food
