Abstract
The utility model relates to an electric heating heater which comprises a casing and an air duct. The air duct is sleeved with the casing, and a hot air outlet and a cold air inlet are formed at two ends of the casing respectively and correspondingly provided with a front mesh cover and a rear mesh cover respectively. The electric heating heater is characterized in that the front mesh cover or/and the rear mesh cover comprises/comprise an outer ring and a round connecting part located at the center of the outer ring, a plurality of air guide plates are arranged between the outer ring and the round connecting part in a radial mode with the round connecting part serving as the center, and every air guide plate is in an arc shape. The sections of the air guide plates are increased; when air generated after a fan rotates passes through the front mesh cover, the direction of the air is effectively changed, so that the air is blown forwards; due to the fact that the air is not in a spiral shape, hot air can be blown very far, a warming speed of a heated area is quickened, and thermal efficiency is improved. Compared with the prior art, the electric heating heater is long in service life and safer, the pitching angle can be adjusted, and the electric heating heater is more practical.
Description
Technical field
The utility model relates to a kind of heating installation, relates in particular to a kind of warmer of electrical heating type.
Background technology
Conventional electric heater comprises housing, is provided with electrothermal tube in housing, and the afterbody of housing is provided with blower fan, and operation principle is to suck cold wind by blower fan, blows out hot blast after blowing over electrothermal tube from the front end of housing.There is following weak point in existing electric heater: 1, adopt diamond wire to protect as guard when practice, surface rhombus guard material is steel wire, during work, the long-term disposal condition of high temperature, when finger or other objects are encountered, be easy to be burned, very dangerous, moreover because the cross section of rhombus net sheet is very little, the cold wind of rear net cover, by after fan blade, forms helical form and blows out, rhombus net sheet does not have the effect that changes wind direction, because wind direction is spiral helicine, fetch is near, and feels under the weather; 2, the motor speed adopting is not high, and seldom, wind speed is not strong for the air quantity blowing out, and fetch is near; 3, existing electrical heating warm-air drier adopts single electrothermal tube, and after electrothermal tube energising, the temperature on electrothermal tube surface is very high, and the hot blast of producing by boasting through motor and fan seldom, and heats inhomogeneous.Because electrothermal tube surface heat can not shed in time, electrothermal tube is worked under long term high temperature, reduces electrothermal tube service life; 4, existing warm-air drier, can not regulate lower angle, on the ground, can only if want to allow hot blast blow to a bit high or lower position, cannot accomplish towards the blowing of direction, and the usability of limits product greatly, if pad some objects, so very dangerous.
