As shown in Fig. 1-Figure 18, first component 1, second component 2 and intermediate layer of material 3 can be comprised according to the air conditioner room unit 100 of some embodiments of the utility model.
Here first component 1 and second component 2 can be two parts that can there is temperature contrast in air conditioner room unit 100.Specifically, first component 1 and second component 2 are fixed to one another, such as be fixed by least one installation component between first component 1 and second component 2, installation component at least comprises fixed structure, can certainly comprise location structure, abutting arrangement etc. further.And will be described in detail in conjunction with specific embodiments below about fixed structure, location structure, abutting arrangement etc., no longer describe in detail here.
As mentioned above, first component 1 and second component 2 need to there is temperature contrast, such as, be at least part of time of running status at air conditioner room unit 100, can the temperature difference be there is in first component 1 and second component 2, in other words, not all can there is temperature contrast in first component 1 and second component 2 during air conditioner room unit 100 whole service state, as can be that these two parts exist the temperature difference within certain a period of time that air conditioner room unit 100 is in running status.
Or, in at least part of time in the scheduled time after air conditioner room unit 100 terminates running status, can temperature contrast be there is in first component 1 and second component 2, in other words, all can there is temperature contrast in the whole scheduled time not after air conditioner room unit 100 terminates running status in first component 1 and second component 2, as can be that a certain section of time memory within this scheduled time is in the temperature difference.
For the ordinary skill in the art, the operational mode of above-mentioned air conditioner room unit 100 can include but not limited to cooling operation mode, heating operation mode etc.
For cooling operation mode, first component 1 and second component 2 may owing to being subject to the impact in various degree of cold air, thus the shrinkage phenomenon (principle of expanding with heat and contracting with cold) occurred in various degree, and need to be fixed to one another due to first component 1 and second component 2, therefore this shrinkage phenomenon in various degree can cause the phenomenon such as part generation fine motion or the changing of the relative positions that matches with second component 2 at first component 1, and noise can be produced at the contact surface place that fine motion or the changing of the relative positions occur when there is this phenomenon, affect the comfort of air conditioner room unit 100.
According to embodiments more of the present utility model, first component 1 can be one in upper air duct shell and lower air duct shell, second component 2 can be in upper air duct shell and lower air duct shell another.Upper air duct shell and lower air duct shell are when air conditioner room unit 100 is in refrigeration or heating operation, be subject to the impact in various degree of cold air or hot-air, therefore may there is temperature contrast at least certain a period of time can run at air conditioner room unit 100, or may temperature contrast be there is equally in certain a period of time after air conditioner room unit 100 run-stopping status.
Be in the wind after shell and lower air duct shell exist temperature contrast, the degree that two kinds of parts expand with heat and contract with cold is different, thus can produce the changing of the relative positions in the cooperation place of two parts, and then generates noise.
But should be understood that, above-mentioned is only that signal illustrates for first component 1 and second component 2 for upper air duct shell and lower air duct shell, can not be interpreted as it is to one restriction of the present utility model.For the ordinary skill in the art, on the basis of having read description foregoing, obviously can in conjunction with the state of the art, know first component 1 and the following relation of second component 2 demand fulfillment: namely first component 1 and second component 2 have installation matching relationship, and temperature contrast can be there is in some cases, can temperature difference be there is in such as air conditioner room unit 100 under being in running status, as long as the first component 1 and the second component 2 that meet above-mentioned condition all drop within protection domain of the present utility model, above-mentioned signal illustrates that can not be understood as or imply into according to the first component 1 of the utility model embodiment and second component 2 must be upper air duct shell and lower air duct shell.Such as, first component 1 can also be one in chassis and face frame, and second component 2 is the another one in chassis and face frame.And for example, first component 1 can also be one in chassis and snail tongue, and second component 2 can also be the another one in chassis and snail tongue.
The producer of air-conditioning also can by the mode of the temperature difference between control assembly, reduce the generation of noise, but with regard to the user demand of user, no matter that user initially starts shooting or beyond the scope of design temperature, namely this indoor temperature is beyond the comfort standard of user, so need cooling rapidly or heat, and make the air themperature in room reach comfort standard, so, the mode of the temperature difference between control assembly, the air handling capacity of air-conditioner must be reduced, cannot actual product be applied to.
Because present inventor has found the problems referred to above, namely air conditioner room unit 100 runs or terminates can there is abnormal sound in a period of time of operation, and the reason that abnormal sound occurs just is that two structural members be fixed to one another cause owing to there is temperature difference degree of expanding with heat and contract with cold different and the changing of the relative positions occurs, changing of the relative positions face can make a noise, thus affects the experience of user.
In view of this, in order to improve above-mentioned situation at least in part, reducing noise simultaneously, noise reduction object can be reached by arranging intermediate layer of material 3.Such as, intermediate layer of material 3 can be arranged between first component 1 and second component 2 and to be arranged at least one place of installation component, and intermediate layer of material 3 at least comprises elastomeric layer or sound-absorbing material layer.
Such as, in certain embodiments, intermediate layer of material 3 can be elastomeric layer, elastomeric layer self is utilized easily to produce the principle of distortion, thus a part for the changing of the relative positions of the instantaneous generation of two structural members can be transformed into the deformation of elastomeric layer, and this part deformation meeting recoverable force slowly, can noise be reduced equally thus.
Adopt the elastic deformation that this elastomeric layer produces when there is the original changing of the relative positions, can in the process of equalized temperature below, progressively move slowly between the free end and the structural member contacted of elastomeric layer, and eliminate the deformation energy of original accumulation, and the mobile noise produced is very faint slowly between the free end of such elastomeric layer and structural member, and comparatively even, be submerged in air-supply noise, obviously impact can not be produced on overall noise.
In other words, elastomeric layer has stiff end and free end, stiff end is and one end be fixed in structural member such as first component 1 and second component 2, free end can be on-fixed end, and this free end can with another in structural member such as first component 1 and second component 2 against coordinating.In certain embodiments, stiff end can be fixed on first component 1 and free end can against second component 2, after there is the temperature difference and the initial changing of the relative positions occur in first component 1 and second component 2, the displacement of stiff end is the displacement being greater than free end, and now elastomeric layer elastic deformation can occur.And in the process reduced gradually in the temperature difference, free end can lentamente to the direction motion that the elastic deformation of elastomeric layer weakens, and when the temperature difference is zero, free end has the position of same displacement with stiff end by moving to, now elastomeric layer eliminates elastic deformation.
According to embodiments more of the present utility model, elastomeric layer has pressing section and fluff, pressing section is folded between first component 1 and second component 2, fluff is positioned at the edge of pressing section, elastomeric layer is arranged to envelope mating surface by pressing section and at least part of fluff from start to finish when the changing of the relative positions occurs for first component 1 and second component 2, namely in the process of the relative changing of the relative positions of structural member, can be extruded between two structural members by more marginate fluff, and remaining fluff still can surround mating surface place, and (namely first component 1 and second component 2 are interconnected the part of cooperation, this connection cooperation place can be abutting arrangement or buckle structure or thread fixing structure etc.), thus make this noise reduction can in the relative movement thereof of total part continuous and effective.
And for example, in further embodiments, intermediate layer of material 3 can also be sound-absorbing material layer, and sound-absorbing material layer can absorb the noise that changing of the relative positions face produces well, thus can play the object reducing noise equally.
Thus, intermediate layer of material 3 can absorb noise effectively, thus improves the situation that air conditioner room unit 100 sends abnormal sound at least to a certain extent, reaches the object of noise reduction.
Other embodiments below for installation component are described in detail.In these embodiments, as illustrated in figs. 8-9, installation component can comprise abutting arrangement, abutting arrangement can comprise the first abutting part 14 and the second abutting part 24, first abutting part 14 can be arranged on first component 1 and the second abutting part 24 can be arranged on second component 2, but be not limited thereto, as the first abutting part 14 can also be arranged on second component 2, the second abutting part 24 can also be arranged on first component 1.
As shown in Figure 9, first abutting part 14 is suitable for abutting to the second abutting part 24, in other words, the first abutting part 14 abuts with the second abutting part 24 and coordinates, and such as the first abutting part 14 can pass through intermediate member (such as intermediate layer of material 3) with the second abutting part 24 and indirectly abut cooperation.
Should be understood that, first abutting part 14 and the second abutting part 24 play auxiliary fixation, now need between first component 1 and second component 2 to realize fixing by other structure, in other words, air conditioner room unit also comprises securing member, and securing member is arranged for fastening first component 1 and second component 2, after the fastening first component 1 of securing member and second component 2, first abutting part 14 will abut on the second abutting part 24, and two abutting parts will produce extruding force at abutting mating surface place.
Further, securing member can be divided into two groups, the fastening strength of these two groups of securing members to first component 1 and second component 2 is different, in other words, wherein one group of securing member fastening strength to first component 1 and second component 2 will be weaker than the fastening strength of another group securing member to first component 1 and second component 2.
Alternatively, this securing member can be the structure such as screw, buckle, and such as one group is that screw is fixed, and another is organized as buckle is fixed, and fixes compared to screw, and the intensity that buckle is fixed is relatively weaker.Thus when the changing of the relative positions occurs for first component 1 and second component 2, the changing of the relative positions major part can concentrate on the first abutting part 14 and the second abutting part 24 contact surface place, is therefore the concentrated generation area of abnormal sound here.And can make to there is larger extruding force between the first abutting part 14 and the second abutting part 24 because the first abutting part 14 and the second abutting part 24 abut cooperation, thus more easily produce noise.
In view of this, as preferred embodiment, intermediate layer of material 3 can be folded between the first abutting part 14 and described second abutting part 24, like this intermediate layer of material 3 is arranged on changing of the relative positions concentrated area, can reduces noise preferably from source.
Below abutting arrangement is described in detail with reference to accompanying drawing.As shown in Figure 9, the first abutting part 14 is configured with the first bearing surface 141, second abutting part 24 and is configured with the second bearing surface 241, and intermediate layer of material 3 is folded between the first bearing surface 141 and the second bearing surface 241.Owing to there is larger extruding force between the first bearing surface 141 and the second bearing surface 241, therefore when the situation of the structural member generation changing of the relative positions, first bearing surface 141 and the second bearing surface 241 place there will be larger abnormal sound, namely abnormal sound concentrates on bearing surface place, by intermediate layer of material 3 being arranged between the first bearing surface 141 and the second bearing surface 241, thus directly effectively can reduce the noise at bearing surface place.
As optional embodiment, first bearing surface 141 can be identical with the shape of the second bearing surface 241, first bearing surface 141 and the second bearing surface 241 can have the contour shape matched thus, thus the extruding force shared better between first component 1 and second component 2, avoid stress too concentrated.Preferably, the first bearing surface 141 and the second bearing surface 241 can be plane, make bearing surface stressed more average thus, avoid local pressure comparatively large and cause larger abnormal sound.
Fixed form about intermediate layer of material 3 can have multiple, and it can be fixed on the first bearing surface 141 place, can certainly be fixed on the second bearing surface 241 place.In other words, adhesive layer can be provided with between one in intermediate layer of material 3 and the first bearing surface 141 and the second bearing surface 241.Thus, fixed.But should be understood that, the fixed form of intermediate layer of material 3 is not limited to this.
According to embodiments more of the present utility model, intermediate layer of material 3 can be configured to sheet, and noise reduction is better thus.Intermediate layer of material 3 can extend along the length direction of the first abutting part 14 and the second abutting part 24, and the width of intermediate layer of material 3 can be roughly equal with the width of the first abutting part 14 and the second abutting part 24, can certainly be less than or greater than the width of abutting part.Preferably, intermediate layer of material 3 can tile be arranged on the first bearing surface 141 and the second bearing surface 241 whole bearing surface on, noise reduction is better thus.
In embodiments more of the present utility model, at least one in first component 1 and second component 2 is configured to flexible laminated structure.In other words, first component 1 can be have certain flexible flaky texture, and second component 2 also can be have certain flexible flaky texture.Such as, at least one in first component 1 and second component 2 can be elasticity of plastics part.
This flaky texture can be not straight flake structure, such as in certain embodiments, shown in composition graphs 8, at least one in first component 1 and second component 2 can comprise such structure, this structure comprises the first arcuate structure 29a, the second arcuate structure 29b and syndeton 29c, syndeton 29c is arranged between the first arcuate structure 29a and the second arcuate structure 29b, and syndeton 29c forms the first above-mentioned abutting part 14 or the second abutting part 24.In other words, when first component 1 is configured to said structure, syndeton 29c will be formed as the first abutting part 14, and when second component 2 is configured to said structure, syndeton 29c is then formed as the second abutting part 24, and this should be easy understand for the ordinary skill in the art.
In one embodiment, as shown in Figure 8, the first arcuate structure 29a and the second arcuate structure 29b all has semicircular arc cross section, but is not limited thereto.In one embodiment, first arcuate structure 29a and the second arcuate structure 29b juxtaposition, and syndeton 29c is connected between one end adjacent to each other of the first arcuate structure 29a and the second arcuate structure 29b, facilitates first component 1 and second component 2 to abut thus and coordinate.
As preferred embodiments more of the present utility model, intermediate layer of material 3 can be flannelette napped fabric layer.The pressure that flannelette napped fabric layer is subject to structural member (such as first component 1, second component 2) has the situation being extruded distortion, and the part be not squeezed can continue to keep original more bulk state.And there is a large amount of air between fiber in length and breadth due to flannelette napped fabric layer, thus flannelette itself has preferably sound absorption function, adds that the situation of this distortion can encase the contact surface made a noise completely, thus obtain higher noise reduction.Particularly, in the situation of the structural member generation changing of the relative positions, a little relative motion is there is between structural member, and in relative movement, have the contact surface that bulk flannelette napped fabric layer is extruded to structural member, meanwhile have new bulk part and surround contact surface, thus make this noise reduction can in whole relative movement thereof continuous and effective.
As other embodiments of the present utility model, intermediate layer of material 3 can also be high-density foam layer, such as polyurethane foam, this polyurethane foam has the noise reduction similar to flannelette napped fabric layer, and not moisture-sensitive, the moisture absorption of this polyurethane foam, thus there will not be the situations such as rotten mouldy, distortion, good noise reduction can be ensured for a long time.
As some embodiments more of the present invention, intermediate layer of material 3 can also be rubber layer, rubber layer self is utilized easily to produce the principle of distortion, thus a part for the changing of the relative positions of instantaneous generation can be transformed into the deformation of rubber layer, and this part deformation meeting recoverable force slowly, can noise be reduced equally thus.
Certainly, be understandable that, above-mentioned flannelette napped fabric layer, polyurethane foam and rubber layer are not limited to for the intermediate layer of material 3 according to the utility model embodiment, for other, there is acoustically effective, the material layer that can reduce noise is equally applicable to the utility model, and such as other has the porous material layer etc. of loose structure.
