Leafless fans send cool this summer

In the summer, do you think that only by turning on the air conditioner can you create a cool one? This is not the case. With the gradual recognition of “air conditioning disease” and the continuous improvement of energy conservation and environmental protection awareness, more and more people have chosen to use electric fans in combination with air conditioners to spend the summer, and electric fans have become an indispensable part of summer life. Or missing a product. This summer, a leafless fan jumped into people's sights. Its fashionable shape, comfortable air volume, and safe design instantly “spike” many consumers.

Modern ideas subvert traditional fans

As a traditional small home appliance, the fan has not changed much in appearance and function over the years. Despite the divisions of table fans, floor fans, air-conditioning fans, and lofty fans, in general, the cool air is blown by the rotation of the blades driven by the motor. The emergence of leafless fans completely broke this design concept.

Leafless fans, as the name suggests, are fans without blades. It is understood that the leafless fan was first produced in the United Kingdom and was invented by the British designer James Dyson. He once said that many people are using the air conditioner, which not only consumes too much power, but also has poor ventilation performance, and there is no leaf fan. Not only is the price lower than the air conditioner, but also the ventilation is stronger. The new leafless fan will compete with the air-conditioning products in the market. Since the appearance of the first leafless fan in 2009, it quickly swept the world. China's home appliance market has also seen similar products soon, and it is gradually welcomed by the market.

In the Meilu Department Store, Quanwu Department Store, and leafless fan display sites in Suzhou, many consumers were attracted. The leafless fan consists of two parts, the lower part is the base of the bracket and the upper part is the outlet of different shapes. There are round, oval and chicken heart shapes. No matter what kind of shape, the lines are smooth and concise. At the same time, leafless fans are matched with white, gray, silver, blue, pink and other colors, full of texture and modern taste. “This kind of styling is very suitable for homes with modern decoration styles.” Mr. Wu, the citizen, has always put it down when he sees no leaf fan.

Blowing cool breeze has "mysteries"

Leafless fans have no fan blades, so how does it blow out the cool breeze? Everyone is very interested in these new gadgets, and they have to stop and try to see if there is any real wind in the “frame” that cannot see the fan blades. “The blowing wind is quite comfortable and cool.” Many consumers who experienced the effects on the scene are full of curiosity.

According to the staff of the DYSON brand of Metro Department Store, the outline of the leafless fan is quite simple. The bottom is a base with an air box above it. The middle of the fan is completely empty. However, the base of the electric fan is not a combination of a simple motor with a power switch and a wind adjustment device. "The base and the fan's air box can be separated and assembled through the bayonet. Apart from the motor inside the base, there are also air inlets covered with dense holes. Here is the most primitive part of sucking air."

The staff member said that when the air enters the base, it is driven by the motor and then sent through a layer of hidden fan blades above the base. This layer of blades is horizontally rotating. After the wind box is installed, it is completely invisible on the outside. After the action of the motor and the fan blade, the air that has already formed a certain airflow enters the cavity inside the air outlet frame, and accumulates to a certain extent beyond the normal air pressure outside the cavity, thus forming wind. The narrow front end of the narrow cavity, will force the internal air flow toward the rear end of the wider cavity movement, the continuous "extrusion" of the air can finally only leak out of the small slit out, continue to run for some time Afterwards, the pressure of the air supply can be gradually strengthened to make the airflow at the air outlet gap faster. Once the airflow at the air outlet is accelerated, a blowing effect is formed, which causes the air around the air outlet frame to follow. When various air currents are superimposed, air supply effects that are several times greater than the ability of the base to absorb air are formed. “The DYSON leafless fans can inhale the surrounding air into the air stream and blow it up 15 times. But even with such a strong effect, the power is not much different from that of a traditional fan, and it is still relatively energy-efficient.”

Pay more attention to safety and cleaning

The leafless fan is free from the traditional mode that the electric fan directly relies on the motor to drive the fan blade to rotate directly, but adds a link after the fan leaves the air, and can achieve a more ideal air supply effect by changing the air flow path. What is most satisfying to consumers is that leafless fans are as windy as they are without blades, and they are superior to conventional fans in terms of safety. A mother who chose a leafless fan at Quanwu Department Store stated that traditional electric fans use blades. Although they have a cover, they still have potential safety hazards. Especially if there are children in the family, they are still uncomfortable with using them. They may worry that the child will not put his fingers in the fan mask. There is no safety issue with this bladeless fan. In addition, this leafless fan is also very easy to clean, so that housewives can "reduce the burden", only need to use a cotton cloth to wipe the smooth and simple outer surface on it, instead of using the traditional fan like to first remove the cover, then wipe the inside Fan blades.

A new generation of leafless fans is on the market and product quality is also uneven. It is understood that professional brands such as DYSON imported products are generally priced at a few thousand dollars, while domestic leafless fans are priced at a few hundred thousand dollars. However, in some online stores, the price of some leafless fans is very low. To this end, professionals warn that some low-priced products have rough shell materials and are noisy when used. Therefore, it is recommended that consumers not only look for prices when buying leafless fans, but should choose good brand products with good reputation and good quality. .
