Below according to description of drawings a kind of form of implementation of the present invention.

Fig. 1 is the ground plan of expression air conditioner module body constructed according to the invention, and Fig. 2 is the schematic diagram of this module body of expression and decorative panel, and Fig. 3 is the module body in the presentation graphs 2 and the profile of decorative panel.

Referring to Fig. 3, label 10 expression embedded into ceiling type air conditioners, this air conditioner hangs for 10 times in the ceiling space 11 that is fixed on house 40.This air conditioner 10 has module body 22 and decorative panel 14 for to blow out the type air conditioner to four direction, has suction inlet 16 in the longitudinal axis central authorities of decorative panel 14, around the suction inlet 16 of this decorative panel 14, also has exhaust outlet 18.By roof 40 side's four bolts 42 that stretched vertically downward, and module body 22 is contained on these bolts 42 with lifting assembly 44.

As shown in Figure 2, in the module body 22 of air conditioner 10, receive fan motor 24 is housed, paddle-wheel fan 26 bends to slightly rectangular heat exchanger 38 and distribution box 36 around them.This heat exchanger 38 separates with dividing plate 28 49,49 of tube sheets, at outer space 56 places of the heat exchanger 38 that is separated by this dividing plate 28, receives draining pump 30, discharge outlet 32 and refrigerant piping 34 or the like are housed.Air when this dividing plate 28 can prevent to move leaks, and because the existence of this dividing plate 28 can guarantee that also heat-exchanged air is blown out to indoor R by the blowing mouth on the four direction 18.

If adopt this form of implementation, then as shown in Figure 1, heat exchanger 38 bent to slightly be shape, and place position around above-mentioned paddle-wheel fan 26, can make the axle center of this paddle-wheel fan 26, dispose in the mode of setovering slightly by middle mind-set dividing plate 28 sides of heat exchanger 38.The axle center of paddle-wheel fan 26 refers to the axle center of fan motor 24 output shafts, and the center of heat exchanger 38, refers to the intersection point of line L1, L2, i.e. the intersection point of longitudinal axis L 1 and minor axis L2.

And as shown in Figure 3, suction inlet 16 places of the decorative panel 14 of air conditioner 10 also can be provided with air cleaner 20.

The following describes the action of this air conditioner.

As Fig. 1～shown in Figure 3, when the fan motor 24 in the main body frame 22 moves, paddle-wheel fan 26 is rotated, after so the air of indoor R can being sucked, is purified by air cleaner 20 by suction inlet 16, deliver to heat exchanger 38, after carrying out heat exchange, blow out to indoor R by the blowing mouth 18 of four positions by this heat exchanger 38.

At this moment, because the corner location in module body 22 is provided with dividing plate 28, so air in that suck by suction inlet 16 and empty after heat exchange, can be by not spilling near draining pump 30, discharge outlet 32, indoor mechanical valve 60 or the like, thus can blow out really to indoor R by the blowing mouth on the four direction 18.

If adopt this form of implementation, because distance L 3 has been put by middle mind-set dividing plate 28 lateral deviations of heat exchanger 38 in the axle center of paddle-wheel fan 26, so shown in the embodiment of back, the voice when comparable original device reduces operation.

Distance L 3 is preferably 100 millimeter, but should change with the size of module body 22.Confirm that now the curved shape of heat exchanger 38 rings little to its shape.Such as the curved shape of heat exchanger 38 can be square, rectangle, also can be ellipse garden shape, circle.Importantly, if adopt this form of implementation, the axle center of paddle-wheel fan 26 should be with respect to the center-biased of heat exchanger 38, and the biased direction in the axle center of this paddle-wheel fan 26 is not limited in a certain direction.For form of implementation shown in Figure 1, the axle center of paddle-wheel fan 26 is to be put by middle mind-set dividing plate 28 lateral deviations of heat exchanger 38, just can reduce voice to this direction biasing, but now confirm, also can put to an opposite lateral deviation of dividing plate 28.

Confirm now, compare that the effect that the voice of back one scheme reduces changes little with the situation of putting to dividing plate 28 lateral deviations.

If so, owing to can reduce the disorder of the wind of paddle-wheel fan 26 discharges,, can reduce the operation voice so compare with original technology.

If with reference to figure 4 and Fig. 5, the voice that is obtained by this form of implementation is detected data (Fig. 4), compare with the voice detection data (Fig. 5) in original technology, can be by obviously drawing among two figure, the device of this form of implementation is compared with original technology, has reduced the operation voice of about 2dB.Promptly in Fig. 4, voice is 48.3dB, and in Fig. 5, voice is 50.3dB.

Referring to Fig. 1, the experimental machine size that this voice detects usefulness is:

Along the size H1=1050mm of the module body 22 of longitudinal axis L1 direction,

The size H2=900mm of heat exchanger 38,

Along the size W1=760mm of the module body 22 of minor axis L2 direction,

The size W2=610mm of heat exchanger 38,

Axle center offset or dish L3=100mm.

For this form of implementation, the result that all voices that carried out detect shows no matter which kind of shape heat exchanger 38 is bent into, as long as the axle center just can reduce the operation voice to certain direction biasing.

With a kind of form of implementation the present invention is described above, but the present invention is not limited to this form of implementation.Such as above-mentioned form of implementation is the example explanation with four direction blowing type air conditioner 10, but the present invention also is applicable to the air conditioner of other type in addition, such as two direction blowing type air conditioners or the like.

As mentioned above, if adopt the present invention, because heat exchanger is around the crooked location of fan, and this Fan axial center and heat exchanger center-biased, or this Fan axial center disposes in the mode by mind-set bulkhead sides biasing in the heat exchanger, so can reduce the disorder of the wind of discharging, and reduce the voice when moving by fan.
