Problems solved by technology

However, there is a boss at the fixed position of the motor of the traditional centrifugal fan in the air inlet direction, and the diameter of the end surface of the boss is more than 30mm. The turbulent flow causes part of the air volume loss, which in turn reduces the air volume distributed at the air inlet between the fan blades, resulting in a decrease in fan efficiency

Embodiment Construction

[0021] Attached below Figure 1-3 The technical solutions of the present invention are further described through specific implementation methods.

[0022] The air cleaner of the present invention includes an impeller assembly 5 . Such as Figure 1~3 As shown, the impeller assembly 5 of the present invention includes the impeller body 51, the impeller body 51 protruding upwards and a boss 54 for accommodating the motor inside it, and a plurality of blades 53, the blades 53 are arranged on the impeller body 51 and surround the boss The outer periphery of 54 is centrifugally distributed outwards, and the top of the boss 54 is conical, and the air flow passes through the conical surface of the boss 54 and transitions to between the blades 53 and then flows out.

[0023] Specifically, the boss 54 includes a cylindrical section at the lower end and a conical section at the upper end, the top of the conical section is hemispherical, the bottom surface of the conical section is adap...

Abstract

The invention discloses an impeller assembly. The impeller assembly comprises an impeller body, a boss which protrudes upwards from the top surface of the impeller body and is used for allowing a motor to be accommodated inside and a plurality of blades; and the blades are arranged on the impeller body and are distributed outwards around the periphery of the boss in a centrifugal mode, the top ofthe boss is in a cone shape, and the airflow passes through the conical surface of the boss to be transited between the blades and flows out. The invention further discloses an air purifier with the impeller assembly. According to the impeller assembly and the air purifier, flow turbulence at the air inlet of air blower can be effectively avoided, the air volume loss can be reduced, and the efficiency of the air blower can be improved.

Description

technical field [0001] The invention relates to the technical field of air cleaning devices, in particular to an impeller assembly and an air cleaner with the impeller assembly. Background technique [0002] With the deterioration of air quality, more and more people begin to pay attention to the impact of air quality on human health. Air purifiers, also known as air cleaners, air fresheners, and purifiers, refer to air pollutants that can absorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria , allergens, etc.), products used to improve air cleanliness, which have been widely used in homes, offices and other places. [0003] The power source of the existing air purifier is a fan, and the operating condition of the fan directly affects the performance of the air purifier. With the improvement of the requirements for air purifiers, the requirements for the noise of the fan ...
