Description
Technical field
The present invention relates to household electrical appliance, specifically a kind of mute energy-saving radiation proof hair dryer adopting electromagnetic induction heating.
Background technology
The household electric blower that existing market is sold, be all using Resistant heating as thermal source, resistance wire heat source efficiency is low, only has about 50%, and firing rate is slow.The fan of traditional electrical blowing is placed in the air intake vent end of hair-dryer, and resistive heater is placed in air outlet, and hair dryer in use air-flow needs to blow over resistive heater, and air-flow is subject to the obstruction of resistance wire, can produce very large noise.Meanwhile, the electric spark produced during the commutation of fan electrode, can produce electromagnetic radiation, also can have an impact to human body.
Summary of the invention
The object of the invention is for overcoming the deficiencies in the prior art, and provide a kind of mute energy-saving radiation proof hair dryer, this hair-dryer adopts electromagnetic induction heating, and through the optimization of structural design, effectively can improve efficiency, reduces noise, reduces radiation.
The technical scheme realizing the object of the invention is:
A kind of mute energy-saving radiation proof hair dryer, comprise hair dryer and be arranged on heater element, the fan in hair dryer housing, unlike the prior art: described heater element is electromagnetic induction heating system, this Operation system setting is between the fan and air outlet of hair dryer housing cavity, and be connected with power supply frequency-variable module, inner walls is provided with electromagnetic shielding material, multiple noise reduction air channel is provided with in case top, communicate with hair dryer air channel, housing afterbody is provided with the expansion air intake vent reducing wind inlet end air velocity.
Described electromagnetic induction heating system is made up of the cylindrical metal urceolus coaxially arranged, metal inner core and the load coil that is wrapped in metal outer cylinder outer wall, wherein: have spacing between metal outer cylinder and inner core.During work, air-flow flows through and is heated by the cylinder surrounding that heats and centre, and electromagnetic induction heating effectively can improve energy utilization rate, realizes energy-conservation object.Meanwhile, the noise produced during airflow passes resistance wire when can avoid adopting Resistant heating.
Described power supply frequency-variable module is arranged in hair dryer handle.
Air Filter is provided with below described noise reduction air channel.
Compared with prior art, hair dryer tool of the present invention has the following advantages:
1. energy-conservation: heating source adopts electromagnetic induction heating, effectively improves the utilization ratio of electric energy, has brought up to 95% from 50%;
2. low noise: adopting the design of low noise airflow channel structure, making air-flow when flowing through in hair-dryer pipe as far as possible, reduces to run into barrier, reduces turbulent air flow, the generation of the pneumatic noise avoided;
3. radiationless: the operating frequency adopting 20-40KHz, electromagnetic radiation intensity, much smaller than the intensity of mobile phone radiation, only has about 1/10th of mobile phone signal electromagnetic radiation, effectively avoids the injury of electromagnetic radiation to human body;
4. blower enclosure adopts electromagnetic shielding material, can reduce the impact of electromagnetic radiation to greatest extent.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention;
In figure: 1. ER effect frequency module 2. metal outer cylinder 3. metal inner core 4. shell 5. induction coil 6. noise reduction air channel 7. fan 8. Air Filter 9. afterbody air intake vent.
Detailed description of the invention
With reference to Fig. 1, a kind of mute energy-saving radiation proof hair dryer, be made up of shell 4 and ER effect frequency module 1, electromagnetic induction heating system, fan 7 and the afterbody air intake vent 9 be arranged in hair dryer, be provided with electromagnetic shielding material in housing 4, the impact of electromagnetic radiation can be reduced to greatest extent; Evenly be provided with multiple noise reduction air channel 6 at housing 4 top, below this air channel 6, be provided with Air Filter 8, communicate with hair dryer air channel; Employing multiple duct designs, and effectively can reduce the air velocity of air intake vent end, effectively reduce the pneumatic noise of air intake vent end; Power supply frequency-variable module 1 is arranged in hair dryer handle; Between the fan 7 that electromagnetic induction heating system is arranged on housing 4 inner chamber and air outlet, be connected with ER effect frequency module 1, this system is made up of the cylindrical metal urceolus 2 coaxially arranged, metal inner core 3 and the load coil 5 that is wrapped in metal outer cylinder 2 outer wall, adopt this cylindric eddy-current heating metal cylinder, when can avoid adopting Resistant heating, the noise produced during airflow passes resistance wire.
During work, first convert 220V input ac voltage to DC voltage, then output to electromagnetic heater after the high frequency low voltage alternating current that frequency-variable module converts 20 ~ 40KHz to.Pipe in the built-in two coaxial tubular ferrous metal of hair-dryer air duct, blower enclosure inner wall surrounding heat induced wire, after wire passes to high frequency electric, can be high frequency variation magnetic field by electric energy conversion efficiently, and the magnetic field of high frequency change can produce induced-current by pipe in ferrous metal, thus causing metal inner pipe to generate heat, fan is blown into air and flows through around cylinder and centre, and through air outlet blowout hot blast.Due to air-flow flow through in coaxial inner tube time, there is no barrier, therefore can not produce larger noise.Meanwhile, air intake vent end adopts and expands inlet air channels designs, reduces air intake vent end air velocity, reduces noise.
