Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
A silencing blower as shown in figures 1-3 comprises
The heat preservation box body 1 is provided with an air inlet 11 connected with an air supply pipe of an air conditioning system and an air outlet 12 connected with an indoor grille;
the damper 2 is positioned in the heat preservation box body 1 and is in a square groove shape, the groove edge 21 of the damper is fixedly connected with the inner wall of the heat preservation box body where the air inlet 11 is positioned and surrounds the air inlet 11, and vent holes 22 are uniformly distributed on the five body walls of the damper;
the first silencing plate 3 is positioned in the heat insulation box body 1 and on the right side of the damper 2, the front surface, the back surface and the bottom surface of the first silencing plate are abutted to the front inner wall, the back inner wall and the bottom inner wall of the heat insulation box body 1, and the top surfaces of the first silencing plate and the inner top wall of the heat insulation box body 1 alternately form first air channels 31;
the second silencing plate 4 is positioned in the heat preservation box body 1 and on the right side of the first silencing plate 3, the front surface, the back surface and the top surface of the second silencing plate are abutted to the front inner wall, the back inner wall and the top inner wall of the heat preservation box body 1, and a second air duct 41 is formed between the bottom surface and the inner bottom wall of the heat preservation box body 1;
a first static pressure box 13 is formed between the first sound-absorbing plate 3 and the left inner wall of the heat preservation box body 1, a second static pressure box 34 is formed between the first sound-absorbing plate 3 and the second sound-absorbing plate 4, and a third static pressure box 14 is formed between the second sound-absorbing plate 4 and the right inner wall of the heat preservation box body 1.
The volume of the first hydrostatic tank 13 is equal to the volume of the third hydrostatic tank 14 and greater than the volume of the second hydrostatic tank 34.
The air inlet 11 is connected with an air supply pipe of an air conditioning system, and the air outlet 12 is connected with an indoor grille. The cold/hot air in a high-speed turbulent flow state of the air-conditioning blast pipe enters the silencing and air-supplying device through the air inlet 11 of the silencing and air-supplying device, firstly, the noise generated by the cold/hot air in a turbulent flow state of the air pipe is primarily blocked by the damper 2 and is changed into a steady flow state to enter the first static pressure box 13, the noise is further silenced by the first silencing plate 3, the flow rate of the cold/hot air is greatly reduced because the volume of the first static pressure box 13 is large and the ventilation sectional area of the first static pressure box 13 is far larger than that of the air pipe, then the cold/hot air enters the second static pressure box 34 between the first silencing plate 3 and the second silencing plate 4 through the first ventilation channel 31 preset at the top end of the first silencing plate 3 to further stabilize, and after the noise is reduced by the second silencing plate 4 again, the cold/hot air enters the third static pressure box 14, and enters the air-conditioned room through the outlet 12.
Therefore, after cold/hot air of the air conditioner enters the silencing and air supply device, the cold/hot air of the air conditioner is subjected to primary noise damping, secondary silencing and six-time flow direction change, the flow rate is reduced, the volume is expanded, the turbulent cold/hot air is changed into steady-flow cold/hot air, and the noise is greatly reduced, so that the influence of the noise generated by high-speed air of an air pipe on an air-conditioning room is eliminated, and the aim of achieving indoor silencing by an air-conditioning air supply system is fulfilled.
Therefore, the silencing air supply device has the main advantage that the aim of indoor silencing can be achieved even if the air conditioning system adopts a high-speed air pipe, and the silencing air supply device has very important significance for solving air conditioning diseases such as tinnitus and the like caused by high noise of the air supply system.
