Household Appliance Engineering Report: Standing Fan

Household Appliance Engineering Report Standing FanHousehold appliancesEngineering reportMaking of carry fan. receivable date24/03/2017The introduction This report explores and examines the history and evolution of the stand fan detailing how they work and the materials employ. The purpose of the report is to illustrate the functions and special features as tumefy as to try information about the social, environmental, sustainability and cultural connection that rose due to development and use of the stand fan. As the time progressed, technologies prevail drastically changed, the use of polymers and smaller sized powerful pushs have allowed the stand fan to be lighter as well as improved operation and lowered the manufacturing cost when compared to heavy metals and bigger motors used in the past. a stand fan is a common household appliance used for chilling an area it is basically a traditional fan set on an adjustable rod cell which is attached to a base, it also contains a t least 3 wind speed range.The earliest model of fans appeared during the 1800s it was basically a bipolar motor attached to a six-leaf wrought flat brass blades. These early fans were both a unique, or an expensive appliance, used in large offices or wealthy homes. The decade of 1910-1920 brought major changes. Around 1910, electric fans were being made for residential use, they had six wings and ran on slower speed and the cages were now made with steel due to lack of brass as well as the blades were locomote in shape and shrank from diameter of 8 down to 5.Description A stand fan is a common household appliance they are oft more effective and popular than other table fans as it can be adjusted to move up and down as well as its head oscillates till 180 degree or remain steady pointing at one direction. A stand fan is just like a normal table fan but its set on an extendable pole which is attached to a base. It has three speed settings and an on off tone ending usually named as 0. This type of fans is usually placed at a corner of the room or in an advantageous location to achieve not bad(p) cooling experience.2.1 How it worksStand/pedestal fan works with the help of an electric motor. A motor consists of coil of wire wrapped around a metal center and when electricity is passed through this, it produces rotational motion and a hub/cap connects the motor with the metallic/ pliable blade which circulates the air around, these blades are shaped on an angle which helps to carry air from one point to another. The control box contains four switches three to control speed and one to turn the fan on or off. The extendable pole can be used to increase or slack the height of the fan.2.2 AssemblySlide the 2-off base tail sections together.Remove the screws from the center of the base cross section, and then fasten the fan pillar in position.Now unscrew and remove the charge plate retainer that locks the dickens support sections together slide over and fit th e plastic base subdue.Set the height of the extension pole and then lock into position with the plastic screwed retainer.Set the motor and switch control section over the extension pole and secure into position with the locking screw.Remove shaft protecting cover and unscrew guard retaining nut/hub/cap anti-clockwise and remove.Take the rear-guard section and slide it over the threaded screw on the fan body (make sure, the handle on the guard is facing upwards).Screw on the plastic nut/hub/cap to secure the rear guard in place.Push the blade on to the motor shaft until it reaches the stop.Screw on the blade retaining cap/hub/nut in a clockwise direction to secure the blade in position.Hook the cause guard on to the rear-guard section at the top.Secure the two guard sections together with the clips around the edges. The screw and nut at the bottom of the grille essential be fitted. atomsGuard (rear and front grill) it is a metal netting used to protect fan blades from any physica l contact this protects the fan from any persecute as well as the exploiter.Motor it is the heart of the fan as it converts the applied electrical energy into mechanical output energy.Blade these are the teeter shaped objects connected to the motor which spins and creates airflowHub/cap it is a device which connects the fan blade with the motor.Extension pole this is the component that makes stand fan special, it allows the user to adjust the height of the fan according to their preference.Head support frame this component gives the stand fan its feature of tilting its head up or down. pitch box/ control box this is the component which contains the electric circuit and switches which controls the speed of the fan as well as turn it on or off.ComponentMaterial made frombladesPolymer/aluminumRear and back grillsteelExtendable polePolypropylene polymer/ metalScrewsMetal (carbon steel/stainless steel) and plastic3.1 MaterialsmaterialscomponentWhy it is used?Polymer/plastic-blad es-Screws-Hub/nut/cap-switch-it is used because plastic would be more safer and cheaper than metals as well as it will decrease the weight of the fan.Metal (carbon steel/stainless steel)-extension pole-screw-guard (front and back grill)-it is used to make the product more durableAdvantages and disadvantages4.1 AdvantageThey are very effortless to assemble also put them away when you are not using it as you can separate the components good.You can move them around the house easily and put them in an advantageous location.Due to its extendable pole, you can adjust its height according to your preference.It is cheap and you can assemble it yourself.Theyre lightweight and can provide cool air over large area.They can be easily cleaned.4.2 disadvantageTheyve less safety for children as they might stick their finger inside(a) the grill.Cooling range is smaller.theres too much noise when the fan runs in higher speed.Impact on societyThis household appliance had a great impact on the soc iety and peoples life. As before the invention of pedestal/stand fan there was only mechanical fans which required people to do energy physically to cool the temperature or circulate air. When pedestal/stand, fan was invented it made peoples life way easier. During the early stage of the invention these fans were only used in big offices or wealthy homes but when refrigerated air was used in commercial buildings the fan makers focused more towards residential use. thence these types of fans started to appear at everyones home. The invention of pedestal/stand fan made life of the people more easier as they were cheaper and easy to assemble as well as it didnt need much maintainance.ConclusionThe making of the stand fan and different materials used in the stand fan has been explored in this report. Pedestal/stand fan is usually made of polymers and metals like stainless steel, aluminum. They are more advantageous than other table or ceiling fans due to its extendable pole which allow s the user to increase and decrease its height according to their preference and also because its cheaper than ceiling fans as well as it is easy to assemble.
