Description

Array type electric fan

The utility model---array fan formula combination bellows relate to the daily-use electrical appliance technical field, generally are used as windchill equipment.

Known to the inventor, electric fan of the prior art is modular electric fan, and the utility model then is to adopt a plurality of modular electric fan forming array formula combination bellows to blow, to reach ideal effect.

Prior art electric fan equipment is generally looked forward to daily-use electrical appliance industry, worker introducing to some extent in the technical data such as low voltage electrical apparatus industry, though of a great variety, there is no as the utility model--the array fan formula makes up the form of bellows.

With regard to the whole world, extensively adopt the opportunity of air conditioner cooling also ripe far away, and be to adopt the electric fan cooling more.Therefore the annual in the world cooling electric fan quantity that needs is surprising.Yet though prior art electric fan kind is a lot, breakthrough new varieties are rarely seen.Thereby how research breaks through the fan kind of existing outmoded structure, obtains more economical, more attractive in appearance, more effective fan new varieties, and this is significant concerning tens its people of developing country.The purpose of the present utility model promptly is this.

The utility model is to adopt a plurality of prior aries unit electric fan to constitute the box-type array combination.In the casing of general rectangle, at least one column unit fan row, settle at least two Unit fans; More favourable scheme is, two row's Unit fans row are set, and every row are settled 3 fans, and 4 adjacent fans are generally rectangle or square arrangement; Certain two row fans also can be staggered, and are purpose with actual effect attractive in appearance in a word.As accompanying drawing is a kind of example that makes up with six unit electric fans, and its general configuration is by the 1--main box body; The 2--face shield; The 3--control box; The 4--timer; The 5--speed control switch; The 6--work indicator light; The 7--battery main switch; 8--electric wire and plug; The 9--back cover; The 10--motor fixed rack; The 11--fan electromotor; Formations such as 12--fan blade.Wherein:

1---main box body: main box body generally adopts the cuboid form.Its size need admit the arrangement of six electric fans.Main box body available metal material, plastics or wood materials etc. are made, and are advisable with attractive in appearance, firm, inexpensive.

2---face shield: face shield adopts venetian blind form or wire gaze form, has both played the safety protection effect, again should be elegant in appearance, inexpensive firmly, ventilate freely suitable.

The 3--control box: control box both can be made into one with main box body, can be made into detachable again.Interior dress control apparatus, switch etc. must be safe, firm, attractive in appearance, inexpensive.

4---timer: mechanical or electronic type.

5---speed control switch: the rotating speed that is used for regulating each unit electric fan.Available continuous speed adjustment formula, also available stepping speed adjusting type.

6---work indicator light: this lamp is bright during fan work.

7---battery main switch: switch on or off the complete machine power supply and use.

8---electric wire and plug.

The above-mentioned the 4th---8 in addition parts select for use based on outsourcing, both looked after attractive in appearance, practical, Security, consider cost price again, so this class other can accommodation select for use by parts.

9---back cover: this cover need be done to such an extent that windage is very little, gets final product with wire gaze more simply.Other materials also can.

10---motor fixed rack: this support firmly connects with main box body, is advisable with steel or aluminum frame.Each Unit fans motor is fixed on this support, and can adjust fixed-direction, so that the user regulates blowing direction and total blowing area size.Briefly, as long as make each fan electromotor axially to subtended angle increase all around, the wind-force active area is just big, otherwise then little.

11---fan electromotor: these power of motor sizes are not limit, general when home-use each power of motor can be 5 watts and do not wait to 25 watts.Power is big more, and air quantity is big more, but whole volume and power consumption also increase.The electric pressure of motor or interchange, direct current are not limit yet.Motor should select efficient, reliable, inexpensive person to be advisable.

12---fan blade: fan blade is advisable well with attractive in appearance, usefulness.Generally select for use the integrated type plastic blade for well.Lobe numbers constitutes one with three to seven blades and all can.Motor and fan blade are big more, and the whole combination of formation is big more, otherwise more little.

Above-mentioned system is arranged as example with the combination of six unit electric fans, does with summary.Can select for use two to eight not wait the unit electric fan to constitute the utility model according to the market demand in addition.

The utility model---array fan formula combination bellows have the following advantages:

One, air-supply is even, and needn't shake the head to make whole room obtain continuous wind, and variable-speed.

Two, because of shaking the head, so safe in utilization, the center of gravity Area of bearing is big, touches and does not have danger.

When three, one or two people dries, need only start wherein one or two unit electric fan, can satisfy the demand, but general using electricity wisely is more than 2/3rds.

Four, aesthetic in appearance, be easy to fix one's room up.Particularly present popular sectional, article are many in the room, and are as long as the utility model is placed on sectional a part, both artistic and practical.

Five, be difficult for toppling over, the personnel that it can be moved to easily concentrate the place, improve the air feed effect.

Six, winter, collection was convenient.

Seven, put into certain liquid summer, can blow a cold wind over; Put into the electric heating equipment winter, but blowing hot-air, a tractor serves several purposes.

When eight, six junior unit electric fan total outputs were suitable with a big electric fan power, air quantity was also suitable.

Its shortcoming is that its cost of preresearch estimates exceeds about 15% than modular electric fan.But from advantages such as aesthetic property, practicability, energy savings, the utility model has potential vitality.

In sum, the inventor thinks that the utility model---array fan formula combination bellows have characteristics such as novelty, creativeness, practicability.From product manufactory technical standpoint, the production technology water average energy of each professional electric fan factory is realized the utility model smoothly at present, and can make something perfect even more perfect, and is in different poses and with different expressions.Present national household fan factory reaches nearly thousand families, and market electric fan day hastens towards saturation.Though the household ventilation fan demand oncoming force is swift and violent, too many because of manufacturer, it is flat-tired that sales trend is also changeed.Therefore the anxious fan new varieties of waiting to release brand-new structure.After adjacent the utility model puts goods on the market, activate the market surely, fan is sold new favourable turn occurred.The inventor thinks the producer that produces the small-sized household ventilation fan, for adapting to the situation that small-sized ventilation fan day hastens towards saturation, changes the line of production immediately and realizes producing the utility model, and is most suitable and favourable.This class factory is as long as transform their existing small-sized ventilation fan motor and the fan blade of producing slightly, even directly adopt, mix suitable casing etc., just can realize the utility model, need not carry out the investment of factory building, equipment, raw material and technical force again, generally just can rake in business economic benefit and social benefit in half a year at the latest to market input bulk article at some months.Concerning above-mentioned producer, the utility model is strictly " short, flat, fast " product, implements the utlity model has wide prospect.
