Embodiment Construction

[0013] The structure for reducing the vortex noise of air-conditioning ventilation of the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 2 As shown, the structure for reducing air-conditioning ventilation eddy current noise of the present invention includes an air-conditioning casing composed of an inner wall P4, an air-conditioning fan P5 installed in the casing, an air-conditioning evaporative heat exchanger P3 arranged on one side of the fan P5, and an evaporative heat exchanger P3 arranged on the evaporator. The air-conditioning dehydration pan P2 on the lower side of the heater P3, the air-conditioning inlet P1 and the air-conditioning outlet P6. The inner wall P4 of the air conditioner housing is an integral lining with an arc surface, and the radius of the arc surface is: R=1.0~1.5L, where R refers to the inner wall side of the air conditioner with the corner of the water tray P2 as the center ...

Abstract

The present invention provides a structure for reducing ventilation eddy flow noise of air conditioner. Said structure includes air conditioner shell body, air conditioner fan mounted in the shell body, air conditioner evaporation heat exchanger placed at one side of fan, air conditioner dewatering tray placed in lower side of evaporation heat exchanger and air conditioner air inlet and air conditioner air outlet. The inner wall of air conditioner shell body is an integral internal lining with curved surface, the radius of said curved surface is R=1.0-1.5L, in which R is that using dewatering tray edge corner as centre of circle, air conditioner inner wall side curved surface is radius of curve and L is width of air conditioner air inlet.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a structure for reducing noise caused by eddy currents in air conditioning ventilation. Background technique [0002] The internal structure of the one-way cassette air conditioner is as follows: figure 1 As shown, it includes an air-conditioning shell composed of inner and outer walls, an air-conditioning fan P5 installed in the shell, an air-conditioning evaporative heat exchanger P3 on the side of the fan P5, and an air-conditioning dehydration tray on the lower side of the evaporative heat exchanger P3 P2 and air-conditioning inlet P1 and air-conditioning outlet P6. When the air conditioner is running, eddy currents are generated at the right angles of the lining surface to cause noise, and as the air conditioner keeps running, the noise is also increasing. At the same time, it also brings discomfort to users. Contents of the invention [0003] In order to solve the deficiencies in ...
