In addition, this report will feature an appendix to display extensive affair of research and freehand drawing towards its parts and functions. The purpose of the report will also show the need for this product in the new technological world and will display e real capability that it has to full extent.1.2 mise en scene Information, historical research of this product.The zap was first invented somewhere in the course of instruction 1946 during a radar related research project. Dr Percy Spenser was part of the project solely during the investigation found some issue very unusual. During the project, they were testing out a new vacuum called magnetron when suddenly he realized that the rout outdy bar in his pocket had melted. This inspired the set up to try out another examine where he placed popcorn kennels near the render and watch joyfully as they stated to pop, cracked and sputtered all over his lab. This fascinated the doctor about this unusual discovery and so prompted another examine the near morning with his colleague. The experiment was placing an egg next to the magnetron and the result was the egg exploding all over the doctors lab. Mr Spenser then came up with a logical scientific experiment the melted bay windowdy bar, the popcorn and egg all had one thing in common they were exposed to low density cook nothing. This conclusion led the doctor that if these foods can be cooked this promptlyly why others cannot be as well. Dr. Spencer then invented a admixture box with an opening into which he fed vaporize power. The energy entering the box was unable to escape, accordingly creating a high uper density electromagnetic field. When the food placed in the box and zap energy fed in, the temperature of the food increased very rapidly. Dr. Spencer knowingly knew he just boded what was to revolutionize cooking, and form the radix of a multimillion-dollar industry, called the atom-bomb oven and put forward a plan to the Raytheon skunk to build this machine .Unsurprisingly, in 1954 the Raytheon Corporation produced the first commercial atom-bomb called the 1161 Radarange. It was large, expensive, and had a power of 1600 watts which wasnt very economical towards multitude who wont rich. To assoil this problem a division of the company named Amana created the first domestic nuke oven in 1967 but sales were slow during the first few years, part overdue to the ovens relatively expensive price tag, later the concept of quick microwave cooking arrived. In succeeding years, a number of other companies joined the countertop microwave oven market. By the end of 1971, the price of microwave oven units began to simplification and their capabilities expanded as measure moved on.1.3 What does the product do?The microwave oven is a kitchen thingmabob that catch fervencys and cooks food by heating up the particles at bottom while exposing it to microwaves from the electromagnetic spectrum. The waves were implemented into the machine where the inventor was experimenting with the it.1.4 Why is there a need for this product?The microwave oven is one of the most in the important kitchen appliances in the modern day household. It provides the basic needs of workaday life and is important contribution towards the world. The machine delivers the most of what modern engineering has as it heats and cooks food rather the old ways of heating them on a grasp or on a bonfire. Moreover, the device is also much safer than the range of mountains as it does not get hot when shareed by heat due to the material its hasten from, which is stain little(prenominal) sword with a coating of acry late resin enamel because of its low thermal conductivity.1.5 Impact on SocietyThe microwave oven has made a significant contribution towards society as it made life easier with a cooking and heating foods at your fingertips. This helps with timesaving and allows to serve individuals inwardly the family at contrasting times when necessary. This is important because it helps some(prenominal) people whom are busy due to the technological world and dont yield the needed time to cook food on the stove. In addition, the microwave allows the food to be cooked much cheaper compared to the olds ways as all the components construct in posture, making life much more simple. This helps some people in the long run with paying the bills and assisting them to pay the more important fees.2.0 commentary2.1 Describe the producti) What it looks like?The microwave oven is a quick and efficient machine that uses electromagnetic shaft syndrome to cook food. This fascinating machine allows people to cook food whenever they are busy or tired afterward a long day at work. This machines tendency is a impertinent prism with to vertical and horizontal lines. In addition, it also has a make in light bulb to see how your food is cooking and has a timer whenever its finished. Most microwaves will catch three ventilations systems to keep the line of descent in the microwave flowing and is utilize to take the actinotherapy out. This rule is necessary otherwise the quality of the food will suffer. Moreover, the machine also has a container at the back where it stores up the microwave energy and pitiable circuit where its connected to the cable that is plugged towards the power point.ii) How it works?The microwave is actually quite a simple machine to how it actually works. The inside generator called the magnetron takes electricity from the power outlet and converts it to high-powered microwaves. These waves then activate through the food compartment and blasted out towar ds the spinning turntable in order to cook the food evenly. Furthermore, the microwaves then bounce of the reflective metal wall however when these waves meet the food they dont bounce but instead penetrate it and oscillate the molecules within it. Therefore, allowing the food to become hotter and let do it your meal.iii) reals applyThe following materials used to make microwaves areStainless poise with a coating of acrylic enamel.Ceramic or glasselectromechanical componentsSteel metal A mixture of cast iron, trade name and bronzyStainless trade namePolymerMedium carbon steelHardened steelPlastic and Copper wireWhy are these materials used?Material Uses Why?Stainless steel with acrylic enamel apply for the remote layer of the microwaveCorrosion ResistanceDuctileLow heat absorptionCeramic or glass utilize for the cooking rearCorrosion ResistanceInsulatorElectromechanical componentsTimer rides, switches and relaysSimple mechanicsConductorsSteel metal employ to make magnetro n tube , the waveguide, capacitance and the stirrer sports fanGreat conductivityGreat durabilityDuctileA mixture of cast iron, steel and bronzeUsed to make the gears mettlesome tensile strengthHigh endurance strengthLow coefficient of brushStainless steelUsed to make pulleysHigh strengthPolymerUsed to make beltsHigh StrengthMedium carbon steelUsed to make screwsHigh tensile strengthMalleableHardened steelUsed to make washersWear resistantBrittlePlastic and slovenUsed to make the cablesGreat conductivitySilicon SteelUsed to make the transformerMagnetic Propertiesiv) How is it assembled?The process of manufacturing the microwave oven starts with the cavity that creates the microwave radiation. First, the bod is formed using automatic metal-forming presser with all of the other parts already made.The parts then move through a paint summons where the paint is heated up to 300 degrees for 20 minutes and all the parts are coated in paint. adjacent this, the crusade verge receives a coat of paint and metal plate is connect to its window.The microwave then moves onto the next phase where it obtains the anode cylinder that will provide with its electricity to generate to power. Moreover, a powerful magnet is then put close to the cylinder to create an electromagnetic field, creating microwaves. A thermal protector is attached flat on the magnetron to prevent damage to the tube from overheating and create an explosion.Additionally, an antenna enclosed in a glass tube is attach on top of the back of the microwave. The waveguide is connected to the magnetron that is a on top of the antenna, while a blower motor is attached directly to the tube. Finally, a plastic fan is attached to the motor. In addition the capacitor and the high voltage transformer are added in as well.The main abut placed on the assembly tray and the cavity is screwed on to the chassis, which is the component that makes all the parts work together. Next, the door is attached to the cavit y and chassis. The magnetron tube is bolted to the side of the cavity and the main chassis.The circuit that produces the voltage required to operate the magnetron tube is then mounted directly on the frame, close to the magnetron tube.The stirrer fan is mounted on top of the cavity attached directly to the fan. Following this, the stirrer shield is screwed on top of the fan assembly. The shield prevents tinkers damn and grease from entering the waveguide, where they could produce damage to the magnetron.The relay provides power to the transformer and a timer for the microwave. The relay is mounted close to the power transformer, while the timer is mounted on the defy board. Also mounted on the control board are a timer bell that rings when your foods heated and a light bulb that allows viewing of the inside. Furthermore, a number of interlinking switches are secured near the top and bottom of the door area to alter cooking options.A previous panel is attached next to the front door. Behind the front panel, the control circuit board is attached. The board, which controls the various programmed trading operations in their proper sequence when the switches are placed on the front panel, is connected to the various components and the front panel using plug-in sockets and cables.The outer baptistery of the microwave is made of stainless steel metal with coating acrylic enamel and assembled on a roll former. The case is strapped onto the preassembled microwave oven and is bolted in firmly. This finally completes the process and the oven is sent for packaging.v) How to use it?The microwave oven is quite a simple machine to use with basic knowledge of a human existences being. The machines main purpose is to cook/heat food and requires minimal trend by having a choice of how to do it. There are many options to cook your food such as defrost, fruits, desserts options and many more. When your choice has been made just click the option and the microwave oven d oes it automatically for you without the need of redness the gas stove.vi) Features and extra.There known to be three different examples of oven that have been used throughout the modern world. The original solo microwave oven, the great grill microwave oven and the new convention microwave. These microwaves have a different variety of cooking options but use the same basic design with components and little adjustments such as moisture sensors and LED lights. There have also been variations changes to outside layer with it just primarily stainless steel. This design could be viewed as a disadvantage because of its electrical conductivity that wouldnt make it safe and would conduct even more heat that leads to greater discover of the microwave overheating and being significantly alter. Nevertheless, the microwave is still a great kitchen appliance that has proven itself to be a vital part for the modern world.4.0Analysis4.1 Critical Judgment of the producti) ComponentsThe compo nents of the microwave such as the magnetron, relay, motors, gears, capacitor, high voltage transformer, chassis and the cavity all do their job efficiently and effectively. However, they are known to have overheated in microwaves causing health hazards over a long catamenia of time due to the immense bill of radiation. In addition, if the microwave is physically damaged or passing waters it whitethorn also cause a problem as it has the chance of causing cancer if the insulator is cracked from high chemical substance exposure. To combat these issues the immense radiation should decrease to stop overheating and the use of less chemicals should be introduced. Overall, most of the components are safe and useful compared to some of the old ones used in the first microwave oven.ii) Materials The materials used in the microwave oven are quite great and work professionally but there a number of significant problems with them. An example of one is the steel used for the components, which may start to corrode after a period of time. This is a major problem as if these components are damaged the microwave may have the potential of permanently shutting down. Moreover, the extensive use of steel may cause the microwave overheating due the high electrical conductivity, which would damage its components . To solve this problems the steel metal should be replaced with less derives of stainless steel to prone electricity and has high corrosion resistant.iii) Sustainability The microwave oven is a great sustainable kitchen appliance. Their almost no problems that is present towards the pictorial environment except for the usage power and possible chemical leak. Furthermore, the use in domestic industry is also not much of a problem as they can be placed where people see especially for seniors who old and fragile. But, this comes to a disadvantage because if microwaves are place within low heights children can play with and cause damage and may even drop it which may lead to high chemical leak if it cracks. In addition, some children could even place a metal objective lens that will likely spark up and cause a fire .The immense radiation may also not be the scoop up suitable options towards kids and seniors as their bodys arent strong enough to take the energy. A new design should come around with there is less radiation used , the containment for the microwave energy should be reinforced with stronger metal and sensors which can let on between food and metal objects.iv) How well it Functions?The microwave is an ex boothent, simple kitchen appliance that requires no work effort but basic human knowledge. The machine almost never lets you down which is why up to 92% of American households have it according to a study conducted in 1994. In addition, the appliance has had improvements over the past 50 years in order for it to be more effectively useful and safe. But, it does need a minor improvement towards the immense radiation and to reinforce the dangerous microwave energy stored in the back, Nevertheless, the microwave oven functions greats with all the components and materials needing slight developments.v) Pros and Cons of the ProductProsGreat simple machine with energy efficiency.Lasts for a long period of time.Almost never fails.Portable. trump out way to cook food without lighting a gas stove.Keeps all nutrients stored in the food untouched. ConsThe microwave may overheat due to radiation that can cause damage.Not healthy for young children or seniors due to heat radiation.If physically broken, chemical leak may damage cellphone tissues, which can cause cancer.Components will eventually rust causing major damage towards the machine.5.0Appendix5.1 Drawings and Photos Magnetron Inside viewHigh Voltage Transformer capacitor 5.2 Extra Relevant Information The microwave oven converts only part of its electrical input into microwave energy. An average consumer microwave oven consumes 1100 W of electricity in producing 700 W of microwave power which has an efficiency of 64%. The other four hundred W is used as heat mostly in the magnetron tube. In addition, any wasted heat or any microwave radiation is sent out through the cooling vents. Additional power is used to operate the lamps AC power transformer, magnetron-cooling fan food turntable motor and the control circuits, which only need about 100 W to all operate. In addition, the microwave oven also uses less energy compared to the gas stove due to all major components already built in. Therefore, the microwave oven is not only cheaper than a gas stove but also uses less energy that could be life-saving towards many people who have to pay more important bills.6.0Recommendations/Conclusions6.1 Recommendations The first recommendation I will make is for the type of material used in the components to be changed as most of them are made from steel metal. This metal is a great option to conduct electricity but over time, it will corrode and cause a majo r damaged towards the microwave oven. To solve the problem I will recommend is to replace the steel metal with stainless steel as its corrosion resistance. Therefore, allowing it to last much longer.The second recommendation that should be designed into the machine is less radiation used in the microwave. Microwave energy is not harmful but people such as seniors or young children may not be able to take the amount of heat present. In addition, even sometimes the immense radiation energy overheat the microwave oven causing high damage towards its components due to them being next to the cavity. To combat this I will recommend reducing the amount of energy the magnetron produces but enough to heat food.The third recommendation that should be introduced to the microwave is the amount of chemicals used in the magnetron. Some magnetrons contains beryllium oxide which if leaked can cause a dangerous lung condition which sometimes could be fatal. Furthermore, all magnetrons contain thori um mixed with tungsten that if leaked and inhaled , can damage cell tissues and cause cancer. To fix this I will recommend taking out most of the chemicals from the magnetron so it does present a health hazard.6.1 Conclusion The microwave oven has a significant impact on the modern world with its extensive abilities to cook and reheat food. The original form of cooking food can be dated back to Stone Age with the use of fire. Next, came the plan of gas stove in the 1820s which required great amounts of gas with a huge price on its tag. In addition, sometimes the gas stove will fail continuously but this issue was brought to the end in the 20th century. The brilliance of Dr Percys Spencer intellectual mind brought out around one of the most important kitchen appliances of todays technological world called the microwave oven. Even though, this machine had a few problems before becoming perfect. However, the advancement of technology repaired these few problems with companies eager to get their hands of this discovery and made further adjustments to its design to make it look incomparable, magnificent and stunning. Furthermore, the microwave oven uses the technology of electromagnetic radiation to bring new life towards cold and frozen food planning it with the most effective and efficient way possible. The microwave oven has a major influence of how the world works with its outstanding and striking capabilities that has been indeed a great achievement by mankind.7.0BibliographyGallawa, J. (2013).
