Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
Referring to fig. 1 to 5, an outdoor direct-fired warm air blower includes a warm air blower body 1, an air outlet 2 and an air return port 3, the air outlet 2 and the air return opening 3 are both arranged at the same side of the warm air blower body 1, the air return opening 3 is connected with an air return pipe 4, one end of the return air pipe 4 far away from the return air inlet 3 can penetrate into the room and extend to the top of the room so as to be used for pumping hot air (hot air is light and is collected at the upper part) at the upper part of the room into the warm air blower body 1, and then the hot air is blown out through the air outlet 2 after being heated, the return air inlet 3 and the air supply outlet are arranged on the same surface, and this face is leaned on the wall installation, the installation of being convenient for, and the rainwater that rains can not get into the equipment the inside along return air inlet 3, return air duct 4 and air outlet 2 all install in the horizontal direction can, do not need extra preparation return air duct 4 and carry out heat preservation to return air duct 4 and handle.
Specifically, electric fan heater body 1 includes heat transfer fan 11, burning heat transfer room 12 and burner, heat transfer fan 11 can be with the air transportation in the return air inlet 3 to burning heat transfer room 12 in, burner is used for burning the heating to the air in burning heat transfer room 12, burning heat transfer room 12 and air outlet 2 intercommunication.
Specifically, the combustion device comprises an ignition control electric box 13, an air inlet 14, a combustion fan 15 and a fuel gas valve 16, wherein the fuel gas valve 16 and the combustion fan 15 are communicated with the combustion heat exchange chamber 12, the ignition control electric box 13 is respectively electrically connected with the combustion fan 15 and the fuel gas valve 16, and the combustion fan 15 can transport air at the air inlet 14 into the combustion heat exchange chamber 12.
The air conditioner also comprises an air cap 17, wherein the air cap 17 is arranged at the air inlet 14. The hood 17 is windproof and rainproof, and rainwater cannot enter the equipment.
A plurality of partition plates 18 are arranged in the fan heater body 1 and used for partitioning the combustion device, the heat exchange fan 11 and the combustion heat exchange chamber 12. Under the action of the partition plate 18, a cavity can be isolated and communicated with the heat exchange fan 11, so that the return air pipe 4 is hidden in the equipment.
And a flange for installing and fixing the return air pipe 4 is arranged on the return air inlet 3.
The working principle of the device is as follows: after the ignition control electric box 13 obtains a signal needing to be started, the combustion fan 15 is started, outdoor air enters the equipment through the blast cap 17 and then enters the combustion heat exchange chamber 12 through the combustion fan 15, fuel gas enters the combustion heat exchange chamber 12 through the fuel gas valve 16, oxygen and fuel gas are ignited and then combusted, and the heat exchange fan 11 blows air into the combustion heat exchange chamber 12 and blows heat out continuously.
This design arranges heat transfer fan 11 in the back of burning heat transfer room 12, blows out the heat, and the heat that the burning produced is avoided in the malleation heat transfer, and the influence of high temperature air to the fan lets heat transfer fan 11 during operation be in the state of high temperature, reduces life.
The combustion fan 15 also blows combustion air into the combustion chamber for combustion (namely positive pressure combustion), so that the phenomenon that the rotating speed and the air quantity are reduced and the tempering phenomenon cannot be caused after dust is accumulated by a wind wheel of the fan is avoided.
The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
