Description

Super quiet window air conditioner

The utility model relates to a kind of window air conditioner structure.

Existing domestic air conditioning roughly is divided into window formula and split type two big classes, and with regard to present level of mass consumption, window air conditioner is compared with split type, because the low material benefit of valency is liked by the consumer still deeply, but from the noise aspect, split type because indoor set separates with off-premises station, noise is much smaller; The noise reduction problem that how to solve window air conditioner is the hard nut to crack in this field always.Window air conditioner generally comprises panel, chassis and housing, housing includes indoor blast chamber and two chambers of outside blast chamber of contiguous panel, be provided with refrigeration compressor between this two chamber, the chassis is provided with refrigeration system, blower system and electrical apparatus control system etc., refrigeration system is made of refrigeration compressor, evaporimeter, condenser, capillary, filter and tube connector etc., wherein evaporimeter places blast chamber front portion, indoor, and condenser places blast chamber rear portion, outside; Commercially available window air conditioner generally only is provided with a fan motor at present, place in the space between inside and outside two blast chambers, it has two output shafts, install respectively and place the centrifugation blade in the blast chamber of indoor and place the interior axial-flow leaf of outside blast chamber, so indoor blast chamber and outside blast chamber are not independent mutually, the noise of compressor, motor and outside blast chamber is easy to reach the indoor, and also having the air blast noise in addition also is the noise that air-swirl produces.Now, there are many producers to begin to improve existing window air conditioner structure, reduce noise by every means, but existing technical scheme generally all is a little to improve on original window air conditioner structure, as notification number is that the Chinese patent " denoising structure of window air conditioner " of CN2098646U discloses by the way that the protruding wall in air channel is installed at the place, centrifugal fan exit position of window air conditioner and reaches noise when reducing air and flowing through the air channel, but it has only solved the noise problem that air-swirl produces.In addition, as everyone knows, it is hot-air at last, cold air down that air distributes by variations in temperature, but existing window air conditioner in the cold wind air-out position of indoor generally all above panel or side, this also is one of reason that causes air-swirl in the machine by its internal structure decision.

The purpose of this utility model provides a kind of anti-acoustic capability better super quiet window air conditioner structure with regard to being for the defective that overcomes above-mentioned prior art.

The purpose of this utility model is achieved in that the indoor blast chamber structure of the former window air conditioner of main improvement, use for reference the indoor machine structure of detachable air conditioner, with the indoor blast chamber be designed to one with the unconnected sealing chamber of outside blast chamber, and to establish panel top be that air inlet, bottom are air outlet, evaporimeter promptly is positioned at after the air inlet of panel top, is provided with through-flow fan blade simultaneously in the porch, exhaust passage of blast chamber bottom, indoor and replaces the habitual centrifugation blade of former window air conditioner;

For the electromagnetic noise of the air blast noise, compressor and the axial-flow leaf that reduce the outside blast chamber better and motor to indoor influence, can also also be that the external wall in its chamber sticks one deck acoustic material at the outer surface of indoor blast chamber; In addition, the outside axial-flow leaf can be used the motor-driven of installing separately, and lining one outer section configuration is L shaped rubber packing between motor and the motor cabinet, with the electromagnetic noise of minimizing motor and the solid transmission of vibration.

Compared with prior art, the utility model has been done bigger improvement to existing window formula structure, make the indoor blast chamber become one with the unconnected separate chamber of outside blast chamber, and structurally improved the flow regime of air-flow, reduce stream swirl, thereby reduced the air blast noise of indoor blast chamber.

Description of drawings:

Fig. 1 is a structure cross-sectional schematic of the present utility model.

Fig. 2 is the three-dimensional split structural representation of the utility model.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, 2, super quiet window air conditioner comprises refrigeration system, blower system and the electrical apparatus control system (23) that constitutes the window air conditioner movement on housing (18), panel (6), chassis (19) and the chassis, housing (18) includes indoor blast chamber (9) and (13) two chambers of outside blast chamber of contiguous panel (6), be provided with refrigeration compressor (21) between this two chamber, be provided with condenser (17) and axial-flow leaf (14) in the outside blast chamber (13), wherein (15) are cover plate, and (16) are liner; Be provided with evaporimeter (7) and through-flow fan blade (1) in the indoor blast chamber (9), refrigeration system promptly is made up of refrigeration compressor (21), evaporimeter (7), condenser (17) and capillary and pipeline thereof; As shown in Figure 1, indoor blast chamber (9) be one with the unconnected sealing chamber of outside blast chamber (13), panel (6) top is air inlet (5), the bottom is air outlet (4), the air inlet (5) that evaporimeter (7) promptly is positioned at panel top afterwards, through-flow fan blade (1) then is arranged on the porch, exhaust passage of indoor blast chamber (9) bottom, the exhaust passage is provided with vertical stator (2) and horizontal stator (3) near air outlet, described through-flow fan blade (1) can adopt low noise plastic packaging motor (22) to drive separately, for eliminating noise better, can also adopt the rubber blanket shock absorbing to install to plastic packaging motor (22), reduce noise transfer, and indoor blast chamber (9) chamber body adopts the engineering plastics manufacturing with the minimizing noise that thunders, and has advantage easy to assembly simultaneously again concurrently.

Be the influence of the electromagnetic noise of the noise that reduces outside blast chamber (13) and compressor (21), axial-flow leaf (14) and motor (11) to the indoor, can stick an insulation material layer (8), (10) at the outer surface of described indoor blast chamber (9), (8) double as gasket seal wherein, thereby reach the purpose of sound absorption and sound insulation, also can play the effect of cold insulation simultaneously.

Be to reduce the noise of motor of outside blast chamber (13) and the solid transmission of vibration, section configuration is L shaped rubber packing (12) outside the lining one between the drive motors (11) of drive chamber's outside axial-flow leaf (14) and motor cabinet (20).

Thermal current sucks from the air inlet (5) of plastic front board top naturally during work, the evaporimeter (7) of flowing through, following current sucks from through-flow fan blade (1) top, after the impeller blasting action, flow out from through-flow fan blade (1) below, vertical stator (2), horizontal stator (3) water conservancy diversion through exhaust passage, indoor blast chamber (9) below blows to the room from the air outlet (4) of plastic front board below again.
