Description
Technical field
The present invention relates to blowing ground machine and its heating device are blown in machine technical field more particularly to a kind of heating.
Background technique
Blow ground machine be it is a kind of by outside air by air inlet suck machine inside, then from air outlet blowout machine.
The body that ground machine usually has volute type is blown, air outlet can be placed on ground and moist place is dried close to ground.It passes
System blows ground machine and generally comprises handle, ventilating duct, motor and wind wheel, and ventilating duct is spiral case shape, and motor and wind wheel are set to and lead
Inside air duct, air inlet and air outlet are respectively arranged on the side and front end of ventilating duct.In order to blow out warm wind, blow inside ground machine also
Settable electric heating body, electric heating body are usually located inside ventilating duct, are passed through by the air-flow that motor drives wind wheel to spin out
Electric heating body is heated, then is blown out from air outlet.However, tradition blow ground machine in the case that blowing hot-air and blow a cold wind over two kinds, air-flow
By path be identical, so that air-flow will also pass through cold electric heating body, due to electricity when needing to blow a cold wind over
Calandria is usually wire mesh, and air-flow will receive certain blocking after wire mesh, leads to the air quantity come out from air outlet
It is smaller, influence efficiency；In addition, when heating, also results in wind-guiding barrel while being added since electric heating body is arranged in ventilating duct
Heat, therefore heat-resisting requirement is proposed to entire wind-guiding barrel.
Summary of the invention
Based on this, the object of the present invention is to provide a kind of heating to blow ground machine, can be switched with air flow condition excellent
Point.
The purpose of the present invention is what is be achieved through the following technical solutions: ground machine is blown in a kind of heating, including ventilating duct, is set to
