Description
Technical field
The present invention relates to a kind of household electrical appliances, particularly a kind of variable-frequency electromagnetic cold and warm air device.
Background technology
At present, the heater kind of the common air conditioning fan on the market has two kinds, and a kind of electrothermal wire heating's of being device, another kind are PTC heaters.The temperature of its heating wire of electrothermal wire heating's device energising back is very high, and its temperature is not about 1100 ℃ when having the wind heating wire! And belong to the naked light heating, as easy as rolling off a logly light airborne inflammable gas, cross slow or stall, the damage equipment even cause fire of will causing danger if meet the fan motor rotating speed; In addition, cold and heat air is regulated fan and is belonged to small household electrical appliance, electrothermal wire heating's device electric power all designs at 2.1KW, when the air conditioning fan that used this structure in the north when winter, temperature was terribly cold, when people extended air conditioning fan-out air port with hand, the hot blast of producing by boasting can feel it is cool, cause the user to be unwilling to use, cause this reason mainly be the too big institute of air-out flow extremely, it is very high to solve the complicated manufacturing cost of this technical problem electrical apparatus control circuit, the unsuitable updating and upgrading of a product.
PTC heater is a kind of positive temperature thermistor, and the resistance that caused by variations in temperature changes relatively, and power just changes thereupon, and PTC heater energising back is not when having the wind heat radiation, and its maximum temperature is about about 230 ℃.Regulate the fan small household electrical appliance as cold and heat air, the PTC heater electric power all designs at 2.1KW, for the safety of warm-air drier and the output of 2.1KW caloric value is arranged, the wind speed flow of the radiatinig corrugated mesh by PTC heater all has strict specification requirement, normal wind speed flow per second is no less than 3 meters, even per second is more than 6 meters, when cold weather, transfer big wind speed to be not suitable for the user and use, the warm effect of the north system in the winter time of we can say can't reach the effect that people require.In addition, the application PTC heater acts on cold and heat air and regulates when fanning the use warm braw, air is essential will be by the radiatinig corrugated mesh of PTC heater, cause airflow obstruction must increase noise, also strengthened simultaneously the blower fan blast pressure, improve the motor power consumption and caused waste, also influenced motor service life.Once more, the application PTC heater acts on cold and heat air and regulates when fanning the use cool breeze, because PTC heater hinders the air outlet that has stopped up the air conditioning fan, causes the increasing noise, and the increasing power consumption reduces air output greatly.In order to address this problem, must increase automatic control system, when needing cool breeze PTC heater is separated the air outlet of air conditioning fan, when needing hot blast PTC heater is reset into the air outlet of air conditioning fan, so just improved manufacturing cost greatly, make complex structure, caused more multiple faults hidden danger; So it also is unfavorable heater members that PTC heater acts on cold and heat air adjusting fan.
