Air purification module and air conditioner indoor unit

Abstract

The invention discloses an air purification module and an air conditioner indoor unit. The air purification module comprises a spray head, the spray head is arranged in a purification air duct, the spray head and a rotating body are arranged in a spaced mode, the spray head is used for providing water sprayed to the rotating body and comprises a pipe body, a water outlet channel extending in the water outlet direction is formed in the pipe body, and the section of the water outlet channel is circular; and a water inlet hole and a water outlet hole are formed in the pipe body, the water outlet channel is communicated with the water inlet hole and the water outlet hole, the axial direction of the water outlet hole extends in the water outlet direction, the water outlet end of the water outlet hole is gradually expanded in the water outlet direction, and the axial direction of the water inlet hole and the center line of the water outlet channel form an included angle and are eccentrically arranged. In the embodiment of the invention, water enters the pipe body through the water inlet hole, forms a spiral water flow in the water outlet channel, and is spirally sprayed out from the gradually-expanded water outlet hole to form divergent water particles to be sprayed on the rotating body, and a tangential initial speed is provided for the divergent water particles through the spray head, so that the refining effect of the water particles is improved, and the purification effect is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air purification module and an air conditioner indoor unit. Background technique [0002] The purification scheme adopted by the air conditioner in the prior art is mainly to install a purification module at the air outlet or air inlet of the air conditioner. There are several methods for purifying the air, (1) use photocatalyst to remove formaldehyde; (2) use electrostatic dust removal technology; 3) HEPA screen drum removes PM2.5. (4) Filtration and purification of ordinary filter elements; (5) Adsorption of negative ions; (6) Adsorption of activated carbon for air conditioners that currently have the function of washing. At present, the mainstream purification methods of air-conditioning products on the market mainly have the following problems: 1. Secondary pollution caused by activated carbon saturation; 2. The catalyst becomes invalid after being covered by dus...

AI Technical Summary

Problems solved by technology

At present, the mainstream purification methods of air-conditioning products on the market mainly have the following problems: 1. Secondary pollution caused by activated carbon saturation; 2. The catalyst becomes invalid after being covered by dust; 3. CADR decreases after the screen cylinder is blocked, and secondary pollution is precipitated; 4. Frequent replacement of screen cylinders increases costs; 5. Incomplete photocatalyst catalysis produces poisons; 6. Electrostatic dust removal technology produces ozone problems; 7. Incomplete HEPA cleaning reduces cleaning efficiency, etc.

However, the existing air purification modules usually adopt a water spray structure with holes on the peripheral wall of the water supply pipe. The water sprayed by this structure is usually a water column or larger water particles. The number of water particles is small and large. When the water particles are too large, it is easy to fail to penetrate the filter, and the effect of accelerating refinement cannot be achieved, which will affect the purification effect
