Description
Technical field
The utility model relates to a kind of ceiling fan.
Background technique
There is following defective in the ceiling fan that existing common condenser type starts: temperature rise, air quantity are little, and efficiency is low, noise is big, and the life-span is short.
The model utility content
The purpose of the utility model aims to provide the ceiling fan of a kind of safe, low efficiency, more environmental protection, big air quantity, wide voltage, life-span length, low noise, wide range speed control, high wind speed, to overcome deficiency of the prior art.
A kind of ceiling fan by this purpose design comprises that set inside has the fan head of motor, the flabellum that is connected with fan head and suspending assembly; Its structure characteristic is that said motor is a brushless electric machine; Brushless electric machine comprises magnet ring rotor and staor winding, and the magnet ring rotor is fixedly connected with the fan head housing; Staor winding is arranged on the magnet ring rotor center, and is connected with power supply through control circuit board.
Said fan head case top is provided with radiating fin.
Said fan head housing comprises loam cake and lower cover, and radiating fin is fixedly installed on the inner top surface of loam cake; The magnet ring rotor is fixedly installed between loam cake and the lower cover; Staor winding is provided with central shaft, and the central shaft two ends are rotationally connected through bearing and loam cake and lower cover respectively; The control circuit board power line is outside central shaft is drawn fan head.
Said control circuit board is the trip ring shape, is provided with over-and under-voltage protective gear and electronics current-limiting apparatus in the control circuit board.
Said suspending assembly comprises suspension rod and is set in going up the lining handleless cup and serving as a contrast handleless cup down outside the suspension rod that the suspension rod lower end is fixedly connected with central shaft through chuck.
The utlity model has the characteristics of safety, low efficiency, more environmental protection, big air quantity, wide voltage, life-span length, low noise, wide range speed control, high wind speed.
Safety: the brushless electric machine temperature rise is less than 40K; Heating hardly, locked rotor current are zero, the under-voltage protection of band overcurrent-overvoltage; Built-in exclusive supercurrent electronics current-limiting apparatus; Automatically shutdown is restarted and can normally be used when stalled fan, has therefore stopped the generation that burns out motor owing to the motor feels hot and cause accidents such as fire.
Energy-conservation: under the situation that is equal to flabellum, wind speed, rotating speed, the input power of conventional fan is 60W, and the input power of brushless electric machine fan is about 30W, and energy-conservation about 50%, Energy Efficiency Ratio reaches ultra one-level.If the running that the brushless electric machine fan does not stop every day, but using electricity wisely in every month is 30W * 24 hour * 30 days=21.6 degree, calculates by every degree electricity charge monobasic, and comparable conventional fan was saved 21.6 yuan of the electricity charge in every month
Environmental protection: because the input power of brushless electric machine fan is about 50% of conventional fan; Reduce power consumption; With the coal power generation is example: the minimizing that gross coal consumption rate is also relative, simultaneously also reduce emission of carbon-dioxide, and the discharging of corresponding minimizing sulfur dioxide, nitrogen oxide, lime-ash, dust.
Air quantity is big: ceiling fan is an example: under the situation that power is equal to, 56 cun traditional ceiling fan air quantity only have 135m
3/ Min, and brushless electric machine ceiling fan air quantity has 270m unexpectedly
3/ Min, discharge quantity of fan is bigger more than 100% than conventional fan.
Wide voltage: owing to adopted brand new technical, the fan input voltage has no effect to fan performance in the scope of 100V-240V, is specially adapted to the area that voltage functuation reaches multivoltage greatly.
Life-span is long: adopt the permanent magnet suspension design, and the steady and smooth more that turns round, it is littler to rub, and temperature rise is low,, oil-impregnated bearing oil is difficult for doing, and the life-span is longer, and electrical machinery life can reach 10 years.
Low noise: adopt space flight lubricant oil oil-impregnated bearing, the permanent magnet suspension design, the steady and smooth more that turns round, it is littler to rub, so noise is lower.
Wide range speed control: the brushless electric machine fan adopts human oriented design, and rotating speed is realized stepless speed regulation from 500RPM/in～1400RPM/Min, follows one's bent.Be specially adapted to during low speed to sleep and regulate the air circulation circulation of air-conditioned room, and the only about 7W of the power when 500RPM/Min, power saving more.
