Air purifier with air outlet externally connected with flow guide port

Abstract

The invention discloses an air purifier with an air outlet externally connected with a flow guide port. The air purifier comprises a shell, a double-suction type centrifugal fan and a filter assembly, wherein the double-suction type centrifugal fan comprises an air duct frame with a certain internal space and a double-suction impeller mounted in the air duct frame; the filter assembly is mounted between the double-suction type centrifugal fan and the shell; the shell is provided with an air suction inlet used for sucking external air into the shell and the air outlet used for discharging filtered air; the air outlet of the shell is externally connected with an upper cover assembly. The upper cover assembly comprises a cover frame with the upper portion open, an air outlet grid used for covering the cover frame and the funnel-shaped flow guide port mounted in the cover frame. The flow guide port is communicated with the outer side of the air outlet of the shell. The air purifier has the beneficial effects that the air outlet volume of the air purifier can be increased while the air inlet volume of the air purifier is increased, and therefore the purification effect of the air purifier is maximized.

Description

Technical field [0001] The present invention relates to an air purifier, and more specifically, to an air purifier with an air outlet connected with a diversion port. Background technique [0002] At present, the air purifiers on the market can be divided into single-suction air purifiers and double-suction air purifiers according to different suction methods. Compared with traditional single-suction air purifiers, double-suction air The air volume is large, the ability to purify more air per unit time, and the air purification efficiency is relatively high. [0003] Such as figure 1 and figure 2 The Chinese patent application No. 201410163365.6 shown is a double-sided filtering air inlet air purifier with a large wind-receiving area of ​​the filter screen, which includes a motor wind wheel, an air duct (30), a front casing (40), and a rear casing ( 50) and a top cover (60). The air duct (30) is provided with a cavity (30a) for accommodating the motor wind wheel and an air outlet...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned technical solution solves the problem of small air intake and low purification efficiency of traditional single-suction air purifiers through the way of double-sided air intake, the double-sided filtered air intake air purifier does not take into account the funnel-shaped external connection of the air outlet. The diversion port is used to increase the air volume, so as to further improve the purification efficiency of the air purifier, which has certain limitations.
