Technical field
The utility model relates to air-conditioning technical field, relates in particular to a kind of chassis assembly and air-conditioner that improves air-conditioner outdoor unit tonequality.
Background technology
The noise of air-conditioner outdoor unit is the sense that the key factor that affects product quality, particularly low-frequency noise more easily cause user psychology and physiological discomfort.Because it is stronger that low-frequency noise penetrates the ability of body of wall, low-frequency vibration is more prone to encourage body of wall vibration, causes indoor radiation low-frequency noise sound field, and interference user is had a rest.
Conventionally, low-frequency noise can be propagated on chassis by compressor foot pad by compressor low-frequency vibration, causes chassis vibration, and then causes adjacent sheet metal component vibration radiation noise.Meanwhile, compressor low-frequency vibration meeting causes foot of chassis vibration, and the vibration of foundation is installed in footing excitation, thereby causes body of wall vibration radiation low-frequency noise; Therefore the low-frequency vibration that, reduces, suppresses chassis and foot of chassis is significant to reducing low-frequency noise.
At present, as shown in Figures 1 and 2, conventional chassis 1 is with foot of chassis 2 in two ends 2-1,2-2 local welding, and footing middle part is not fixedly connected with chassis.In the case, there is more low frequency modal in compressor bolt pin installation site, and compressor bolt pin place is subject to vibrational excitation and is easy to excite these low frequency modals, causes the low-frequency vibration radiation low-frequency noise on chassis.
Utility model content
Main purpose of the present utility model is to provide a kind of chassis component for outdoor unit of air conditioner and air-conditioner, is intended to reduce the low-frequency noise of air-conditioner outdoor unit.
In order to achieve the above object, the utility model proposes a kind of chassis component for outdoor unit of air conditioner, comprise: the footing on chassis and the described chassis of support, the two ends of described footing are respectively equipped with the two ends connecting portion for connecting footing and chassis, between two two ends connecting portions of described footing, are provided with the middle interconnecting piece that at least one connects described footing and chassis.
Preferably, described footing welds or is fixedly connected with by screw with described chassis at described two ends connecting portion and middle interconnecting piece.
Preferably, described two ends connecting portion and/or middle interconnecting piece are lug boss.
Preferably, described footing is two, is distributed in the two ends on described chassis.
In addition, the utility model also proposes a kind of air-conditioner, comprises chassis component for outdoor unit of air conditioner as above.
A kind of chassis component for outdoor unit of air conditioner and the air-conditioner that the utility model proposes, make full use of the rigidity of foot of chassis, be fixedly connected with chassis in footing middle part, can retrain chassis vibration, reduce the closeness of chassis low frequency modal, and promote the local mode intrinsic frequency of chassis at compressor bolt placement of foot place, effectively to reduce the low-frequency noise of air-conditioner outdoor unit.

Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 3-Figure 5, the utility model the first embodiment proposes a kind of chassis component for outdoor unit of air conditioner, comprising: the footing 2 on chassis 1 and the described chassis 1 of support, and described footing 2 is at least two, the present embodiment is taking two footing 2 as example, and two footing 2 are distributed in the two ends on described chassis 1.
The two ends of described footing 2 are respectively equipped with the two ends connecting portion for footing 2 is fixedly connected with described chassis 1, in addition, are provided with the middle interconnecting piece that at least one connects footing 2 and chassis 1 between two two ends connecting portions of footing 2.The present embodiment is given an example to be provided with a middle interconnecting piece between two two ends connecting portions of footing 2, thus, forms three connecting portion 3-1,3-2,3-3 between chassis 1 and footing 2.
Footing 2 welds or is fixedly connected with by screw with described chassis 1 at above-mentioned each connecting portion 3-1,3-2,3-3.
As a kind of embodiment, above-mentioned each connecting portion 3-1,3-2,3-3 can be lug boss, certainly, can also be set to as required other shapes or structure, to facilitate connection footing 2 and chassis 1 as object.
Due to existing chassis 1 with footing 2 only in two ends local welding, footing 2 middle parts are not fixedly connected with chassis 1, this two ends are fixedly connected with mode the chassis 1 region large area of compressor below are not tied, in the case, there is more low frequency modal in air conditioner compressed machine bolt pin installation site, and compressor bolt mounting points low-frequency vibration amplitude is larger, be easy to excite chassis 1 low-frequency vibration, cause the low-frequency vibration radiation low-frequency noise on chassis 1.
The present embodiment is considered: the rigidity of chassis 1 footing 2 is larger, make full use of the rigidity of chassis 1 footing 2 at this, be fixedly connected with chassis 1 in footing 2 middle parts, the mode that adopts footing 2 to be fixedly connected with chassis 1 multiposition, utilize footing 2 to retrain chassis 1 low-frequency vibration, reduce the closeness of chassis 1 low frequency modal, and promote the local mode intrinsic frequency of chassis 1 at compressor bolt placement of foot place, can effectively reduce the low-frequency noise of air-conditioner outdoor unit.And compared to existing technology, do not increase cost.
As shown in FIG. 6 and 7, the utility model the second embodiment proposes a kind of chassis component for outdoor unit of air conditioner, be with the difference of above-mentioned the first embodiment, in the present embodiment, between two two ends connecting portions of footing 2, be provided with two middle interconnecting pieces, thus, between chassis 1 and footing 2, form four connecting portion 4-1,4-2,4-3,4-4.By chassis 1 with footing 2 at footing 2 two ends and the mode that is fixedly connected with of the multiposition of footing 2 interludes, utilize footing 2 to retrain chassis 1 low-frequency vibration, reduce the closeness of chassis 1 low frequency modal, and promote the local mode intrinsic frequency of chassis 1 at compressor bolt placement of foot place, can effectively reduce the low-frequency noise of air-conditioner outdoor unit.
