Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The internal circulation type aging room heating device shown in the attached figure 1 comprises a device shell 1, a heating pipe 2 and an air supply device 3; the device shell 1 is made of sheet metal, an outer cavity 11 and an inner cavity 12 are formed in the device shell, the outer cavity 11 surrounds the periphery of the inner cavity 12 (namely the outer cavity and the inner cavity are in a shape like a Chinese character 'hui'), and the upper sides of the outer cavity and the inner cavity are communicated; the outer cavity 11 is provided with an air inlet, the inner cavity 12 is provided with an air outlet, and the air outlet is arranged at the lower side of the inner cavity 12; the heating pipe 2 is arranged in the device shell 1 and used for heating air flowing through; the air supply device 3 is disposed in the inner cavity 12 and configured to blow air heated by the heating pipe 2 out of the air outlet. An air return shutter 4 is arranged at the air inlet; the air outlet is provided with a four-way adjustable air supply shutter 5. Preferably, the four sides of the outer cavity 11 are all provided with the air inlet, that is, the four sides of the device shell 1 are all provided with the return air louvers 4. The air supply device 3 is an outer rotor fan.

With the above arrangement, when the air blowing device 3 is operated, while the air in the device case 1 is blown out from the air outlet, the air is sucked into the device case 1 from the return air louver 4, and the return air louver 4 guides the air so that the air flows through the heating pipe 2 from the outer cavity 11 in a certain direction, is heated by the heating pipe, and is blown out from the four-direction adjustable air blowing louver 5 by the air blowing device 3, thereby forming a circulation.
