Wall-hanging air purifier

Abstract

The invention relates to a wall-hanging air purifier. The wall-hanging air purifier comprises a purifier shell with an air purifying apparatus inside, wherein an air inlet is formed in a front panel of the shell, air outlets are formed in two side walls of the shell, the purifying apparatus comprises two fans, air outlets of the two fans are respectively communicated with the air outlets in the two side walls of the shell, air inlets of the two fans are respectively communicated with an outlet of an air filter, an inlet of the air filter is communicated with the air inlet in the front panel of the shell, each fan comprises an impeller shell and an impeller which is arranged in an inner cavity of the impeller shell and fixed on an impeller shaft, the impeller shaft is connected with a driving apparatus. A key point of the invention is that a gap between the impeller shell and the impeller forms a ventilation air duct, an air protection ring 15 which is coaxial with the impeller is arranged on the impeller shell inner wall, adjacent to a peripheral ring of the impeller, of the ventilation air duct, and the diameter of an air stop annular plate is 6 to 10mm greater than that of the impeller. The wall-hanging air purifier is small in air resistance, smooth in air discharging, high in working efficiency, good in performance, capable of greatly lowering the noise, high in air outlet efficiency and capable of greatly improving the performance.

Description

technical field [0001] The invention relates to an indoor air purifying device, in particular to a wall-mounted air purifier. Background technique [0002] At present, on the wall-mounted air purifier, on the one hand, the air outlet mostly uses two or more ultra-thin small blowers, and the air enters from the middle of the front centrifugal impeller and the air is discharged from the surroundings. The disadvantage is that the air volume is small and the noise is large. The improved wall-mounted air purifier uses a plate-type volute air duct, or several small blowers, with front air inlet and side air outlet. The air duct is designed as two side-by-side air ducts, and the motor drives the centrifugal impeller to rotate. , the airflow is inhaled through the middle of the centrifugal impeller, and under the action of centrifugal force, it flows out from the air outlet along the inner wall of the air duct at a certain speed.

Problems solved by technology

[0002] At present, on the wall-mounted air purifiers, on the one hand, the air outlet mostly uses two or more ultra-thin small blowers, which enter the air from the middle of the centrifugal impeller on the front and exit from the surroundings. The disadvantage is that the air volume is small and the noise is large.

The improved wall-mounted air purifier uses a plate-type volute air duct, or several small blowers, with front air inlet and side air outlet. The air duct is designed as two side-by-side air ducts, and the motor drives the centrifugal impeller to rotate. , the airflow is inhaled through the middle of the centrifugal impeller, and under the action of centrifugal force, it flows out from the air outlet along the inner wall of the air duct at a certain speed. However, the disadvantages of this device are large wind resistance, low efficiency, and high noise; on the other hand, the air purifier Most of the air outlet ducts are volute structures, and most of the impellers are front centrifugal impellers. The main working principle of the plate air purifier is that the impeller rotates at a high speed under the drive of the motor, and the air is sucked into the impeller from the middle of the impeller. The air inside is pressurized by centrifugal force and flows out along the volute at a certain speed

However, the volute air purifier has the disadvantages of large wind resistance, low efficiency, and high noise, which seriously affects the normal work and rest of the residents, and consumes a lot of power, low-end performance, and low cost performance.
