The specific embodiment
Below in conjunction with accompanying drawing 1-3 the said cassette air conditioner of the utility model and first embodiment that is applied to the noise reduction grid of this cassette air conditioner are described.As shown in Figure 1, the cassette air conditioner comprises casing 10, spiral case 20 and heat exchanger 30, and this casing 10 comprises air inlet 11 and air outlet 12.Spiral case 20 is connected with air inlet 11, comprises air entry 21 and the air outlet 22 that communicates with the air inlet 11 of casing 10.Motor and impeller (not shown) are installed in spiral case 20.Through the effect of motor and impeller, realize the circulation of air draught, the gas in the casing 10 is discharged by air outlet 22, thereby forms the rotation of negative pressure through spiral case 20 impellers simultaneously, sucks air draught by air entry 21.Casing 10 set inside heat exchangers 30, carry out heat exchange by spiral case 20 inhaled airs through heat exchanger 30 after, through air outlet 12 outputs of casing 10, to accomplish heat exchange.
In addition, be provided with the dividing plate 405 that equidistant vertical ground is arranged at the leeward side of noise reduction grid 40, dividing plate is welded in the both sides up and down that housing 402 is parallel to ground.Shown in Fig. 2 (A), the lee face of said noise reduction grid 40 is provided with fixed mechanism, and said fixed mechanism is a slotted collar 401.Noise reduction grid 40 is through slotted collar 401 dismountable being fixed on the heat exchanger 30.Slotted collar 401 is fixed on the dividing plate 405 through screw.Accordingly, the diverse location of dividing plate 405 is provided with fixing hole.Thus a plurality of slotted collar 401 can be set on noise reduction grid 40, make noise reduction grid 40 fixed.In addition,, therefore can make the noise reduction grid 40 described in the application be applicable to the heat exchanger of different model, increase its applicability because slotted collar 401 has certain elasticity.In addition, said fixed mechanism also can be selected spring clip.
Preferable, as shown in Figure 4, also can be with wind deflector 403 horizontally sets, be rotationally connected with the frame longitudinally 402 of framework; And vertically be provided with, be rotationally connected with the horizontal frame 402 of framework, promptly be set to respectively equally spacedly arrange perpendicular to ground and the equally spaced ground that is parallel to.In addition, dividing plate 405 is set to 4, is respectively 2 of being parallel to ground and perpendicular to 2 of ground.Said dividing plate 405 is welded in the sidewall of housing 402.Fixed mechanism is fixed on the said dividing plate 405 through screw.
Preferable, the area of section of said noise reduction grid 40 windward sides greater than heat exchanger 30 windward sides area of section.The wind circulation that the air inlet 11 of casing 10 is got into is crossed noise reduction grid 40 and is realized the distinguished and admirable rectification through heat exchanger 30 is filtered arrangement with rambling diffuse reflection sound wave, thereby the vortex that reduces in the casing 10 is distinguished and admirable, to reduce noise.Wherein, windward side one end of wind deflector 403 is set to the streamlined structure towards ground inclination, when wind deflector 403 is in the position that is parallel to ground, can effectively reduce distinguished and admirable windage through wind deflector 403 thus.
Preferable, also can further realize reducing distinguished and admirable windage through changing the structure of wind deflector 403 through wind deflector 403.Specifically, as shown in Figure 3, windward side one end of wind deflector 403 is set to " V " type streamline structure, and the little end of wind deflector 403 areas of section is towards the windward side.
In addition, the utility model also provides second embodiment, and the difference of second embodiment and first embodiment is the structure of wind deflector in the noise reduction grid.Specifically, as shown in Figure 5, wind deflector 403 two is parallel to the horizontal segment on ground by what have difference in height, and the tilting section towards ground inclination that connects said two horizontal segments constitutes.Thus, wind deflector 403 can directly intercept the noise conduction of horizontal direction.Said wind deflector 403 is fixed in the two side of frame 402 perpendicular to ground.
Because the distinguished and admirable side that concentrates on suction opeing 22 of air outlet 22 outputs of spiral case 20, the air output at air outlet 22 centers is less relatively.Be not difficult thus to infer, bigger at casing 10 inner noises all around with respect to the center.In view of this, the utility model also provides the 3rd embodiment, and the structure of noise reduction grid 40 is improved.As shown in Figure 6, all wind deflectors 403 are set to the arcuate structure of noise reduction grid 40 center curvatures dorsad, and, arrange more sparse away from the wind deflector 403 of noise reduction grid frame 402 near the wind deflector 403 of noise reduction grid frame 402 comparatively dense of arranging.Can be directed against distinguished and admirable skewness thus, reduce its noise.
Be pasted with sound-absorbing material on the housing 402 of said casing 10 inwalls and noise reduction grid 40.Further reduce noise thus.Said sound-absorbing material comprises that sponge, rock wool, glass fibre cotton or polyester fiber etc. have the material in space.
The above is merely the preferred embodiment of the utility model;, in a word, not all within the spirit and principle of the utility model in order to restriction the utility model; Any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
