Embodiment 1
The utility model provides a kind of method for improving indoor set noise, by applying handicapping on the drain pan 1 of machine indoors
Buddhist nun's rubber layer 2 reduces the wind in air channel 4 to increase the quality in the air channel 4 formed between the drain pan 1 and evaporator 6
Machine 3 and the resonance in air channel 4, and pass through the further reduction air channel 4 of the shock-absorbing and noise-eliminating effect generation nearby of damping glue cortex 2 itself
Noise.The air channel 4 is the passage of drain pan 1 and the supply cold wind discharge formed between the evaporator 6 of the top of drain pan 1, described
The external port in air channel 4 is connected with wind deflector 10 and lower wind deflector 11, and snail tongue 8, the snail tongue 8 are also set up on the air channel 4
In the side of blower fan 3, and at the external port in air channel 4.
The quality for being coated with the drain pan 1 of damping glue cortex 2 compares the quality of the drain pan 1 for being not coated with handicapping Buddhist nun rubber layer 2
It has been increased that, and the eigentone of drain pan 2 can deviate original vibration frequency because of the change of its quality, in blower fan 3
In running at high speed, easy and blower fan 3 the frequency of the vibration frequency in air channel 4 staggers, and reduces air channel 4 with this and blower fan 3 resonates
Problem, reached the purpose of noise abatement.Meanwhile, the material of damping glue cortex 2 inherently has the function of vibration and noise reducing, in noise hair
When raw, partial noise is actively consumed, vibrated the interior friction for being converted into damping glue cortex 2, sound wave is converted into other forms
Dissipate, further up to the purpose of noise reduction.
The damping glue cortex 2 is at least applied and is provided on the drain pan 1 of the lower section of air channel 4.When machine runs indoors, produce
It is exactly blower fan 3, air channel 4 and evaporator 6 that the place of raw noise is main, and wherein main noise comes from blower fan 3 and air channel 4, in order to reach
To the purpose for preferably improving indoor set noise, damping glue cortex at least is coated with the drain pan 1 in the outside of air channel 4, to reduce wind
Noise at road 4.
The utility model additionally provides a kind of bottom case structure of indoor set, as shown in figure 1, including on rear side of indoor set
Drain pan 1, at least part of drain pan 1 encloses the outside in the air channel 4 for being provided at the lower section of blower fan 3, at least encloses located at the lower section of air channel 4
Damping glue cortex 2 is coated with the drain pan 1.It is heat-insulated that the outside of the drain pan 1 being located at least in below air channel 4 is coated with drain pan
Layer 5, the damping glue cortex 2 is applied and is located in the middle of drain pan thermal insulation layer 5 and drain pan 1.
Usually because on fixed load bearing wall indoors more than indoor set, the noise that indoor set rear side is produced is by load bearing wall
The reflection and refraction of wall serve a certain degree of amplification, are further exaggerated the noise of indoor set.Abut in metope
On the indoor set drain pan 1 at noise abatement it is just extremely important because at least enclosing on the drain pan 1 of the lower section of air channel 4
Damping glue cortex 2 is also coated with, emphasis serves the effect got twice the result with half the effort for the noise abatement at air channel 4.
The damping glue cortex 2 is applied and is located in the middle of drain pan thermal insulation layer 5 and drain pan 1, and the damping glue cortex 2 is needed when being coated with
To be pasted using adhesive, it is described because being connected by stickup between drain pan thermal insulation layer 5 and drain pan 1 in the prior art
Damping glue cortex 2 has preferably elasticity relative to drain pan 1 and drain pan thermal insulation layer 5, and it is heat-insulated that the damping glue cortex 2 is located at drain pan
Structure in the middle of layer 5 and drain pan 1 reduces operation difficulty during stickup.The damping glue cortex 2 will keep pasting when pasting
Uniformly.The drain pan thermal insulation layer 5 serves the effect of insulation, and during specific implementation, the drain pan thermal insulation layer more than 5 uses foam
It is made.
For preferable heat insulation effect, the edge of the damping glue cortex 2, the drain pan 1 and drain pan thermal insulation layer 5 connection
Holding is tightly connected, in case the generation condensation because drain pan 1 and damping glue cortex 2 meet under worst cold case with air, influences room
The normal of interior machine is used.
The osculum being connected with drainpipe 7, the damping glue are offered on the drain pan 1 and drain pan thermal insulation layer 5 respectively
The draining resigning region corresponding with osculum is also vacated on cortex 2, draining resigning region profit described in handicapping Buddhist nun rubber layer 2 is not coated with
In installation of the drainpipe 7 in osculum.The damping glue cortex 2 is empty in the draining resigning region of osculum when being coated with
Go out, the draining resigning region is more than the diameter of osculum, when being assembled in order to machine indoors, by drainpipe 7 from osculum
Stretch out, and seal washer is arranged with respectively on the osculum and the drainpipe in osculum 7.
The top of the blower fan 3 is additionally provided with evaporator, in order to further reach more preferable muting function, positioned at air-conditioning
Damping glue cortex 2 is filled on the drain pan 1 of the rear side of indoor set, amplification effect of the fixed wall to noise is further reduced.Simultaneously
Also the vibration of evaporator is converted into the interior friction of the damping glue cortex 2 on the drain pan 1 of the rear side positioned at indoor apparatus of air conditioner.
During specific implementation, it is also possible to be coated with the damping glue cortex 2 on the left and right side plate of machine indoors, further subtract
Noise produced by few both sides of air channel 4.The damping glue cortex 2 can also be coated with the front side board of machine indoors, further subtracted
Noise produced by few evaporator front side.The damping glue can also be coated with the left and right side plate and front side board of machine indoors
Cortex 2, further reduces the noise produced by noise and the evaporator front side produced by the both sides of air channel 4.
The utility model additionally provides a kind of indoor set, the bottom case structure with described indoor set.
Embodiment 2
As different from Example 1, the damping glue cortex applies the inner side for being located at drain pan, when the damping glue cortex is coated with
At the inner side of drain pan, its apart from air channel distance closer to, directly absorb air channel in generation noise ability it is stronger.
Or the damping glue cortex applies the outside for being located at the drain pan thermal insulation layer, then the damping glue cortex is coated with work
Skill is more simple, and the quality requirement to being coated with is relatively low, while also acting the effect of protection drain pan thermal insulation layer.
In sum, the quality for being coated with the drain pan 1 of damping glue cortex 2 compares the bottom for being not coated with handicapping Buddhist nun rubber layer 2
The quality of shell 1 has increased, and the eigentone of drain pan 2 can deviate original vibration frequently because of the change of its quality
Rate, in blower fan 3 runs at high speed, easy and blower fan 3 the frequency of the vibration frequency in air channel 4 staggers, and air channel and blower fan are reduced with this
The problem for resonating, has reached the purpose of noise abatement.Meanwhile, therefore material inherently has vibration and noise reducing to damping glue cortex 2
Function, when noise occurs, actively consumes partial noise, is vibrated the interior friction for being converted into damping glue cortex 2, and sound wave is turned
Turn to other forms to dissipate, further up to the purpose of noise reduction.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and can not by any way be construed to the limitation to the utility model protection domain.Based on explanation herein,
Those skilled in the art associates other specific embodiments of the present utility model by would not require any inventive effort,
These modes are fallen within protection domain of the present utility model.
