Description
Technical field:
The utility model is a kind of outdoor machine of body-separated air-conditioner, and particularly a kind of silencing outdoor machine that reduces running noises belongs to the renovation technique of outdoor machine of body-separated air-conditioner.
Background technology:
When existing detachable air conditioner was worked, off-premises station was owing to the operation of compressor and outdoor fan produces stronger vibration and noise.Usually, the frequency range broad of the noise that outdoor fan produced, comparatively even in the energy issue of each frequency band, show as mild sound of the wind.The vibration of compressor and piping system is the main vibration and the noise source of off-premises station.The noise that compressor operating produced is very high at the frequency multiplication position of driven compressor supply frequency energy, shows as the noise in a shrill voice of feature frequency, and the people is had the fidgets.In order to reduce the noise of air-conditioner outdoor unit, the particularly noise that compressor operating produced, usually utilize sound-absorbing material such as many hollow fibers felt be wrapped in compressor and fluid reservoir around.
In addition, in the off-premises station casing, central dividing plate can be set, Figure 1 shows that the structural representation of existing outdoor machine of body-separated air-conditioner, comprise off-premises station lamina tecti 1, condenser 2, support bar 3, electric machine support, 5, fan electromotor, 6, fan, 7, central dividing plate, 8, appliance mounting panel, 9, right plate 4, electrical equipment lid 10, compressor 11, pipe arrangement 12, preceding plate body 13, base body 14, central dividing plate 7 be divided into condenser chamber and compressor chamber with outdoor shell with off-premises station.The heat exchanger chamber that the off-premises station casing is divided into airtight substantially compressor chamber and carries out heat exchange with air, thus the noise that compressor produces is cut off in compressor chamber.Owing to the outdoor fan that runs up is housed in the heat exchanger chamber, and the pipe arrangement in the compressor chamber may be out of shape in transportation, and therefore central dividing plate and outdoor fan and pipe arrangement must keep certain interval when air-conditioner designs.In order to make full use of the space of outdoor casing, central dividing plate is bending at the fore-and-aft direction of off-premises station casing usually.For effective intensity that guarantees the off-premises station casing, and prevent that rainwater from entering compressor chamber, central dividing plate all is to make of the panel beating material, and acoustically effective is very poor.Therefore, each face of compressor chamber all is to form with panel beating materials processing, and interfixes by screw or screens, and compressor also is to be fixed on the base of off-premises station casing by foundation bolt.Such stiff sheet frame structure not only can absorb vibration and cause structural failure easily, and is unfavorable for the vibration isolation, the vibration noise that compressor produces can be delivered to the external world by frame structure, and the vibration of off-premises station casing is very big to the standard point noise contribution.
In addition, some manufacturers have adopted the miniaturized outdoor unit design of cancellation central dividing plate for the structure that makes off-premises station is more compact.But the off-premises station casing is open like this, and the noise that compressor produces is easy to be delivered to the external world by the heat exchanger chamber.In addition, because compressor chamber and heat exchanger chamber do not isolate, rainwater is easy to enter compressor chamber by the heat exchanger chamber, the water resistance that is installed in the power board in the off-premises station casing is affected, and may since around the compressor icing cause heating operation the time compressor can't start.
The utility model content:
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of vibrational structure that improves the off-premises station casing is provided, and improves the silencing outdoor machine that reduces running noises of the comfortableness of air-conditioner.
