Drawings
Fig. 1 is a perspective view of an embodiment of the present invention, fig. 2 is a sectional view of the embodiment of the present invention, and fig. 3 is a usage state diagram of the embodiment of the present invention.
Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the embodiment of the present invention includes: casing 1, casing 1 are equipped with supply-air outlet 2 and return air inlet 3, are equipped with the wind channel in the casing 1, are equipped with centrifugal fan 4 in the wind channel, and the wind channel all communicates with supply-air outlet 2, return air inlet 3, and return air inlet 3 establishes on casing 1 upper portion, and supply-air outlet 2 is located casing 1's inboard, and supply-air outlet 2 is the bar. The return air inlet 3 is located outdoors, the air supply outlet 2 is located indoors at the doorway 9, so that the air supply outlet 2 and the return air inlet 3 are not located in the same air area, return air and supplied air cannot be mixed, and the air quality of the area where the return air inlet 3 is located is superior to that of the area where the air supply outlet 2 is located. The air duct above the fan is an air return section air duct 5, and the air duct below the fan is an air supply section air duct 6. The air return section duct 5 is L-shaped. An inclined partition plate 7 is arranged in the air supply section air duct 6, so that the air supply section air duct 6 forms a variable-section air duct, and the uniformity of air outlet is ensured. Be equipped with filter screen 8 in the wind channel between supply-air outlet 2 and return-air inlet 3, filter screen 8 is connected on the filter screen frame and in inserting the casing through the bar hole on the casing 1 to the change of filter screen is convenient for. The filter screen 8 can adopt a primary filter screen or a medium filter screen, or a mixture of the primary filter screen and the medium filter screen to further purify the return air. The centrifugal fan 4 purifies the outdoor air through the filter screen, and then the outdoor air is sent to the indoor door through the air supply outlet, so that the convection of the indoor air and the outdoor air is blocked, and the indoor air quality is effectively improved.
As an improvement of the utility model, the air return inlet can be arranged in another room as long as the air quality is superior to that of the area where the air supply inlet is positioned.
The above description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the invention, and many modifications may be made to the embodiments without departing from the spirit or scope of the invention. Therefore, all technical solutions the same as or similar to the present embodiment fall within the protection scope of the present invention.
