Description

“A SMART SUSTAINABLE DUAL ZONE BLADELESS AIRFLOW DEVICE”
FIELD OF THE INVENTION
The present invention relates to a bladeless fan. More particularly, the present invention pertains to a smart sustainable dual zone bladeless airflow device to provide aerodynamically optimized performance, while ensuring safety, comfort, and high utility.
BACKGROUND OF THE INVENTION
Basically, a ceiling fan is a fan mounted on the ceiling of a room or space electrically powered, which uses hub-mounted rotating blades to circulate air. The ceiling fans help in circulating air effectively by increasing air speed. The ceiling fans do not reduce air temperature and/or relative humidity, unlike air-conditioning equipment but create a cooling effect by helping to circulating air and increasing heat exchange via convection. The ceiling fans add only a small amount of heat to the room mainly due to waste heat from the motor, though partially due to friction. The ceiling fans use significantly less power than the air conditioning units as cooling air is thermodynamically expensive.
Also, a ceiling fan is also used in winters to bring warm air, which naturally rises, back down to occupants and this affects both thermostat readings and comfort of the occupant, thereby improving climate control energy efficiency. The ceiling fans have multiple functions, such as the ceiling fans increase mixing in a ventilated space, which leads to more homogenous environmental conditions, moving air is generally preferred over stagnant air, especially in warm or neutral environments, so the ceiling fans are useful in increasing occupant satisfaction and as the fans do not change air temperature and humidity, but move it around, fans aid in both the heating and cooling of a space.
Due to this, the ceiling fans are often an instrumental element of low energy heating, ventilation and air conditioning (HVAC), passive cooling and/or natural ventilation systems in buildings. Depending on the energy use of the ceiling fan system, the ceiling fans provide an efficient way to improve the thermal comfort by allowing for a higher ambient air temperature while keeping occupants comfortable. The ceiling fans are an especially economic choice in warm and humid environments.
There are various types of ceiling fans such as cast-iron ceiling fans, direct-drive ceiling fans, skeletal motors fan, friction-drive ceiling fans, gear-drive ceiling fans, internal belt-drive ceiling fans, brushless direct current (BTDC) ceiling fans and smart ceiling fans. The cast- iron ceiling fans have a cast-iron housing, which encases a very heavy-duty motor, usually of the shaded-pole variety, these motors are lubricated by means of a thrust bearing submerged in an oil-bath and must be oiled periodically, usually once or twice per year.
The direct-drive ceiling fans employ a motor with a stationary inner core with a shell, made of cast iron, cast aluminum, or stamped steel, which revolves around and it is commonly known as a “spinner” motor. The blades are attached directly to the shell. The direct-drive motors are the least expensive motors to produce and on the whole are the most prone to failure and noise generation. The skeletal motor fans have an open-frame “skeletal” design, which allows for far better ventilation and therefore a longer lifespan. This is in comparison to a regular design of a direct-drive motors, in which the inner working of motor are completely enclosed within a tight metal shell which may or may not have openings for ventilation and even when openings are present, they are almost always small to the point of being inadequate.
The brushless direct current (BTDC) ceiling fans use brushless direct current (BTDC) technology, which offers much higher efficiency than the normal ceiling fans driven with traditional alternate current (AC) motors. These are quieter than alternate current (AC) motor fans due to the fact that they are commutated electronically and use permanent magnet rotors. Among other advantages, these fans offer high efficiency, lower noise level, less rotor heat, integration of remote control and other convenience technologies. The only drawbacks are the high cost and the presence of complex electronics which may be more prone to failure and difficult to service.
However, with the advent of new technologies and better quality control techniques, the brushless direct current (BTDC) fan is becoming less of a concern. Those are wired to alternate current (AC) wires along with alternate current/ direct current (AC/DC) adaptor. A vast majority of these fans use brushless direct current (BLDC) motors due to their microcontroller based design, flexibility in fine controls and firmware upgrade capability. The speed, brightness and timing of the fans is easily adjusted with a smartphone app.
US6881037B2 provides a two-piece safety mechanism for ceiling-mounted fans comprises a first and second cable. The first cable has a first fastener extending from a first end and a first connector extending from a second end. The first fastener is for operable association with a first fastening mechanism for securing the first cable to a fan. The second cable has a second fastener extending from a first end. The second fastener is for operable association with a second fastening mechanism for securing the second cable to a ceiling support. The second cable also has a second connector extending from a second end, which is release ably attachable to the first connector to form a continuous cable. The claimed invention also provides for a ceiling fan having the two-piece safety mechanism for retaining the fan in close proximity to the ceiling support if its normal mounting apparatus should fail. The main drawback of this invention is that the ceiling fans are not smart and/or remote operated and ceiling fans create a singular flow zone so dual zone comfort is difficult to achieved, this invention does not have any provisions of integration of an air purifier, further this invention does not help in carbon footprint reduction.
US9254459B2 provides systems and methods for an air purifier with over pressurization relief, including the following components. A room air inlet is configured to fluidly receive air from a room. A supply duct inlet is configured to fluidly receive air from a forced air system. An air filter and or air purification means is configured to filter/ purify air. An outlet is configured to expel filtered/ treated air into the room. A bypass damper system has at least one air filtering mode position and a bypass mode position. A pressure control mechanism is configured to automatically allow the bypass damper system to move from at least one air filtering mode position to a bypass mode position when the air received from the supply duct inlet exceeds a bypass threshold. The bypass mode position guides air from the supply duct inlet into the room without requiring passage through the filter and the outlet. The main drawback of this invention is that the when the air purifier is used instead of a ceiling fan, it uses more electricity and generate lesser flow. Moreover, the air purifiers are plugged inside a corner of the room which is not an optimum position to clean the entire room effectively.
At present there are various devices used for circulating air indoors such as ceiling fans, air conditioners, air purifiers and similar devices. However, the existing devices have various disadvantages associated with them such as the ceiling fans provide good air flow yet the flow is turbulent. Also, the ceiling fans are unsafe, the ceiling fans have poor aesthetics and moreover, the ceiling fans are not smart and/or remote operated. Also, the ceiling fans create a singular flow zone so dual zone comfort is difficult to achieved. Generally, the ceiling fans do not come with an air purifier.
The split air conditioners use crossflow and/or tangential fans similar, however, the air conditioners (AC) are generally positioned on the wall, therefore the flow from the air conditioners (AC) of fan is laminar but generally it moves lower volumes of air and cannot create dual flow comfort zones. The direction of flow of air is also not optimum thus making it less useful as a replacement for a fan. The filter used in air conditioners fail to clean fine particulate matter. The air purifiers are meant for cleaning very fine pollutant particles from the air. The air purifiers are meant to be used for 10-20 minutes every day depending on pollution level. These air purifiers are not a replacement for a fan because if used as a fan, they use more electricity and generate lesser flow. The air purifiers are also plugged inside a corner of the room which is not an optimum position to clean the entire room effectively.
Therefore, there is a need of an aerodynamic bladeless ceiling fan device with air-purifier for ensuring safety, aesthetics, comfort and utility, which reduces the electronic wastage created due to multiple devices by combining them in one including air heater, ceiling fan, air purifier, and air conditioner safety.
