Abstract
The utility model relates to an air purification's technical field discloses low noise formula air cleaner, include preceding shell, fan, filter screen, backshell, air intake and be used for the air exit with the air escape who purifies the completion, still include and fall the device of making an uproar, fall make an uproar the unit bit in the fan with between the air exit, fall and make an uproar the device including releasing the speaker of wave form with the opposite sound of wave form of the noise of fan rotation formation. The utility model discloses in the low noise formula air cleaner that provides, it falls the device of making an uproar can emit special sound, it is opposite that this sound and fan rotate the noise wave form that forms, the two back cancel each other out that meets in the air, the denoising sound that disappears makes low noise formula air cleaner last air -purifying with comparatively quiet state.
Description
Technical field
The utility model relates to the technical field of purification of air, particularly relates to low noise type air cleaner.
Background technology
Air cleaner is a kind of common electronic equipment, and it has air inlet and air outlet, and air is cleaned discharge after flowing into air cleaner.Due to many reasons such as power of motor, rotation speed of the fan, dust accumulation, purification process, especially under fan high speed conditions, air cleaner has larger noise, go out to spread out of from air outlet, in use affect Consumer's Experience, if reduce power of motor, then purification efficiency can be caused to reduce.
Utility model content
The purpose of this utility model is to provide low noise type air cleaner, is intended to solve the problem that in prior art, air cleaner noise is larger.
The utility model realizes like this, low noise type air cleaner, comprise the exhaust outlet that fore shell, fan, filter screen, back cover, air inlet and the air for having purified are discharged, also comprise denoising device, described denoising device is between described fan and described exhaust outlet, described denoising device comprises the loudspeaker that can discharge waveform sound contrary to the waveform of noise
Further, described loudspeaker be arranged at adjacent described exhaust outlet position and towards described exhaust outlet.
Further, described denoising device also comprises the microphone that can accept sound, the processor that can accept voice signal calculating waveform according to described microphone, and described loudspeaker is controlled by described processor.
Further, described microphone is arranged at described fan wind outlet.
Compared with prior art, the low noise type air cleaner provided in the utility model, its denoising device can release special sound, this sound is contrary with the waveform of the noise that fan turns is formed, the two is cancelled out each other after meeting in atmosphere, eliminate the noise that fan turns is formed, make low noise type purification of air function with comparatively quiet state continuing purge air.
Accompanying drawing explanation
The structural representation of the low noise type air cleaner that Fig. 1 provides for the utility model embodiment;
The operation principle schematic diagram of the denoising device that Fig. 2 provides for the utility model embodiment;
The sound wave principle of cancellation schematic diagram that Fig. 3 provides for the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the realization of concrete accompanying drawing to the present embodiment.
As depicted in figs. 1 and 2, the present embodiment provides low noise type air cleaner, muffling type air cleaner, and comprise fore shell 1, filter screen 2, fan 3, back cover 6, air inlet 7, exhaust outlet 8, at exhaust outlet 8, place is provided with denoising device 9.Because silencing means 9 is arranged on the inside of back cover 6, its structure not shown, can understand according to Fig. 2 in FIG.
As shown in Figure 2, denoising device 9, between fan 3 and exhaust outlet 8, plays the waveform sound contrary with noise waveform by loudspeaker 93.Air enters from air inlet 7, between fan 3 and exhaust outlet 8, form air channel, and denoising device 9 is positioned at this air channel.As shown in Figure 3, its sound 100 sent of denoising device 9 is contrary with the sound wave of the noise 200 that fan turns is formed, and two kinds of sound waves are waveform 300 after cancelling out each other, and are initiatively eliminated by the noise that fan turns is formed, after making air flow through denoising device 9, realize the effect that noise reduction is quiet.
So, adopt the low noise type air cleaner in the present embodiment, without the need to changing the power of self, by active noise reduction, noise being reduced, makes its mute, can not annoying noise be heard when user uses, improve user experience.
Loudspeaker 93 in the present embodiment is near exhaust outlet 8, and towards exhaust outlet 8, what the sound discharged can be very fast is passed to exhaust outlet 8 place.
Denoising device 9 can add up the shape information of noise and record in advance, draws the sound of its inverted waveform, released by loudspeaker 93 according to the information of record.Also can collection in worksite, denoising device 9 in low noise type air cleaner in the present embodiment as shown in Figure 2, also comprise microphone 91, processor 92, microphone 91 Real-time Collection noise information, reverse in processor 92, release noise reduction by loudspeaker 93, the waveform of noise reduction release sound can be changed according to noise state under different conditions, there is more outstanding active noise reduction performance.
In order to reduce the impact of surrounding environment, the microphone 91 in this enforcement is also arranged on adjacent fans 3 place, is positioned at the wind outlet of fan 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
