Small appliance

Small appliance is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Small appliance rather than just read about it. In short: A small domestic appliance (also known as a small electric appliance or minor appliance or simply a small appliance, small domestic or small electric) is a portable or semi-portable machine, generally used on table-tops, counter-tops or other platforms, to accomplish a household task. Examples include microwave ovens, kettles, toasters, humidifiers, food processors and coffeemakers.

Key takeaways

  • Small appliance belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Small appliance to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Small appliance from memory before moving on to harder problems.

Reference excerpt

A small domestic appliance (also known as a small electric appliance or minor appliance or simply a small appliance, small domestic or small electric) is a portable or semi-portable machine, generally used on table-tops, counter-tops or other platforms, to accomplish a household task. Examples include microwave ovens, kettles, toasters, humidifiers, food processors and coffeemakers. They contrast with major appliances (known as "white goods" in the UK), such as the refrigerators and washing machines, which cannot be easily moved and are generally placed on the floor. Small appliances also contrast with consumer electronics (British "brown goods") which are for leisure and entertainment rather than purely practical tasks. Small appliances are often mechanically simple devices, typically built around a single heating element, fan, set of blades or similar mechanism with only a few mechanical linkages, which generally makes them straightforward to repair.

Uses Some small appliances perform the same or similar function as their larger counterparts. For example, a toaster oven is a small appliance that performs a similar function as an oven. Small appliances often have a home version and a commercial version, for example waffle irons, food processors, and blenders are small household appliances. A food processor will perform the tasks of chopper, slicer, mixer as well as juicer. Instead of buying multiple small appliances, you can buy a single food processor. The commercial, or industrial, version is designed to be used nearly continuously in a restaurant or other similar setting. Commercial appliances are typically connected to a more powerful electrical outlet, are larger and stronger, have more user-serviceable parts, and cost significantly more. These commercial versions are capable of performing heavy tasks in one go.

Types and examples

Small appliances include those used for :

Beverage-making, such as electric kettles, coffeemakers or iced tea-makers Cleaning, such as vacuum cleaner Cooking, such as on a hot plate, microwave oven, or specialty dish cooking appliance, such as rice cookers Lighting, using light fixtures Thermal comfort, such as an electric heater or fan Many small appliances perform a combination of the above processes such as mixing, heating by a bread machine

Prices

Small appliances can be very inexpensive, such as an electric can opener, hot pot, toaster, or coffee maker which may cost only a few U.S. dollars, or very expensive, such as an elaborate espresso maker, which may cost several thousand U.S. dollars. Most homes in developed economies contain several cheaper home appliances, with perhaps a few more expensive appliances, such as a high-end microwave oven or mixer. A few small appliances like chopper, juicer, grinder and mixer may cost you a few dollars. Instead of buying separate units, a food processor will generally be less expensive. Sometime these kinds of smart appliances saves money as well as space.

Powering

Many small appliances are powered by electricity. The appliance may use a permanently attached cord that is plugged into a wall outlet or a detachable cord. The appliance may have a cord storage feature. A few hand-held appliances use batteries, which may be disposable or rechargeable. Some appliances consist of an electrical motor upon which is mounted various attachments so as to constitute several individual appliances, such as a blender, a food processor, or a juicer. Many stand mixers, while functioning primarily as a mixer, have attachments that can perform additional functions. A few gasoline and gas-powered appliances exist for use in situations where electricity is not expected to be available, but these are typically larger and not as portable as most small appliances. Items that perform the same function as small appliances but are hand-powered are generally referred to as tools or gadgets, for example a hand cranked egg beater, a grater, a mandoline, or a hand-powered meat grinder.

Safety

Small appliances which are defective or improperly used or maintained may cause house fires and other property damage, or may harbor bacteria if not properly cleaned. It is important that users read the instructions carefully and that appliances that use a grounded cord be attached to a grounded outlet. Because of the risk of fire, some appliances have a short detachable cord that is connected to the appliance magnetically. If the appliance is moved further than the cord length from the wall, the cord will detach from the appliance.

Designations and regulations

Designations and regulations of "small appliances" vary by country and are not simply determined by physical sizes. For instance, United States Environmental Protection Agency regulations mandate that small appliances must meet two standards:

Completely manufactured, charged, and sealed in a factory Contains five pounds or less of refrigerant The designations and regulations of "small appliances" are very important in order to assure the safety of the public. Here are some rules and regulations for small appliances:

Altering the design of certified recovered small appliances in a way that would affect the equipment's ability to meet the certification standards is strictly prohibited The equipment must meet the minimum requirements for certification

Industry There are a variety of categories of small appliances and various companies specialize in certain categories. Some categories are dominated by only a few companies, especially white-label manufacturers such as Midea Group; for example, in 2021 The New York Times reported that most American microwave ovens are produced by Midea, including ovens sold by major brands such as Toshiba, Whirlpool, and Black+Decker, excluding companies which produce microwaves separately such as Haier under the GE Home Appliances brand and Panasonic which has its own China manufacturing facilities.

Worked examples

Example 1 — a first encounter with Small appliance

Start with the simplest possible case. Write down what Small appliance claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Small appliance before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Small appliance ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Small appliance

In research
Small appliance appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Small appliance in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Small appliance is common in secondary-school and first-year university syllabi. It links to neighbouring topics Home appliances, so understanding it makes those chapters shorter.
In everyday life
Look for Small appliance outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
