EASY DISPOSABLE FAN BLADE COVER

Abstract

Abstract A fan is a powered machine used to create a flow of air. A fan consists of a rotating arrangement of vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors. but other sources of power may be used, including hydraulic motors, handcranks and internal combustion engines. The Solution Provided in this invention is easy disposal of dust formed on the fan blades. A Fan blade Cover which is made of any heat resistant elastic material is gloved to the blades of the fan. This can be a disposal type, where after the formation of dust on it can be replaced. The Stress in cleaning fan blades is made easy. Exhaust fan in Kitchen areas absorb lot of oil and grease on it, cleaning is very difficult. This Easy disposable fan blade cover helps to solve the problem.

Introduction

Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to compressors which produce high pressures at a comparatively low volume. A
fan blade will often rotate when exposed to an air-fluid stream, and devices that take advantage of this, such as anemometers and wind turbines, often have designs similar to that of a fan.

Typical applications include climate control and personal thermal comfort (e.g., an electric table or floor fan), vehicle engine cooling systems (e.g., in front of a radiator), machinery cooling systems (e.g., inside computers and audio power
amplifiers), ventilation, fume extraction, winnowing (e.g., separating chaff from cereal grains), removing dust (e.g. sucking as in a vacuum cleaner), drying (usually in combination with a heat source) and providing draft for a fire. Some fans may be indirectly used for cooling in the case of industrial heat exchangers.

Background

History
The punkah (fan) was used in India about 500 BCE. It was a handheld fan made from bamboo strips or other plant fiber, that could be rotated or fanned to move air. During British rule, the word came to be used by Anglo-Indians to mean a large swinging flat fan, fixed to the ceiling and pulled by a servant called the punkawallah.

For purposes of air conditioning, the Han dynasty craftsman and engineer Ding Huan (fl. 180 CE) invented a manually operated rotary fan with seven wheels that measured 3 m (10 ft) in diameter; in the 8th century, during the Tang dynasty (618-907), the Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the rotary fan became even more common during
the Song dynasty (960-1279).

In the 17th century, the experiments of scientists including Otto von Guericke, Robert Hooke and Robert Boyle, established the basic principles of
vacuum and airflow. The English architect Sir Christopher Wren applied an early ventilation system in the Houses of Parliament that used bellows to circulate air. Wren's design was the catalyst for much later improvement and innovation.

Objectives
1. To provide easy cleaning of ceiling/wall mounted fan.
2. To provide easy cleaning of Exhaust fan.
3. To provide disposal kind of accessory for preventing the formation of dust.

Summary of the Invention
While fans are effective at cooling people, they do not cool air, but rather work by evaporative cooling of sweat and increased heat convection into the surrounding air, due to the airflow from the fans. Thus, fans may become less effective at cooling the body if the surrounding air is near body temperature and contains high humidity.

The Solution Provided in this invention is easy disposal of dust formed on the
fan blades. A Fan blade Cover which is made of any heat resistant elastic material is gloved to the blades of the fan. This can be a disposal type, where after the formation of dust on it can be replaced. The Stress in cleaning fan blades is made easy. Exhaust fan in Kitchen areas absorb lot of oil and grease on it, cleaning is very difficult. This Easy disposable fan blade coyer helps to solve the problem.

Detailed Description

Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal
combustion engines.

This invention is easy disposal of dust formed on the fan blades. A Fan blade Cover which is made of any heat resistant elastic material is gloved to the blades of the fan. This can be a disposal type, where after the formation of dust on it can
be replaced. The Stress in cleaning fan blades is made easy. Exhaust fan in Kitchen areas absorb lot of oil and grease on it, cleaning is very difficult. This Easy disposable fan blade cover helps to solve the problem.
