With reference to the accompanying drawings, an example of the present invention is described.
Fig. 1 is the ground plan of expression air conditioner main body of the present invention, and Fig. 2 is the figure of this main body of expression and decorative panel, and Fig. 3 is the main body of presentation graphs 2 and the sectional view of decorative panel.In the drawings, 10 expression ceilings bury the type air-conditioner, this air-conditioner 10, and as shown in Figure 3, lifting down is fixed in the ceiling space 11 of building 40.This air-conditioner 10 is a kind of cubic type air-conditioners of supplying gas, and has main body 22 and decorative panel 14, and the central authorities of decorative panel 14 have air entry 16, have air taking port 18 around the air entry 16 of decorative panel 14.Four bolts 42 are arranged on the building 40 vertically downward, and these bolts 42 are used for fixing the hanging hook of main body 22.
Distribution box 36, the heat exchanger 38 of usefulness controlled in discharge outlet 32, refrigerant pipeline 34, running that fan electromotor 24, turbofan 26, dividing plate 28, draining pump 30, draining pump are housed in the main body 22 of air-conditioner 10.
Turbofan 26 and the corresponding installation of fan nozzle 26a.Heat exchanger 38 bends to roughly rectangular round turbofan 26, be contained in four direction air taking port 18 near.Dividing plate 28 connects between the tube sheet 49,49 of heat exchanger 38, in the outer space 56 of the heat exchanger 38 that this dividing plate 28 is separated out, is adorning discharge outlet 32, indoor mechanical valve 60 of draining pump 30, draining pump etc.Dividing plate 28 prevents that when air-conditioner turns round the air that turbofan 26 is sent here from spilling, because the existence of this dividing plate can be guaranteed to send into indoor R by the air of heat exchange from the air taking port of four direction.
According to this example, as shown in Figure 1, distance between the tube sheet 49,49 of heat exchanger 38 is littler than existing air-conditioner (with reference to Fig. 5), and the dividing plate that connects between this tube sheet 49,49 28 interior side-prominent around part 29 heat exchanger 38 of draining pump 30.Like this, in the outer space 56 of the heat exchanger 38 that is separated out of dividing plate 28 draining pump 30, indoor mechanical valve 60 etc. can be installed easily.This dividing plate 28 also can roughly extend straight around the part 29 of draining pump 30.At this moment, the two ends of the part 29 that extends straight are connected with bend 31,31, and this bend 31,31 is contained in to be installed than on the more close tube sheet 49,49 of existing air-conditioner (with reference to Fig. 5) each other.
This fan electromotor 24 rotates turbofan 26, and like this, room air is just sucked from air entry 16, delivers to heat exchanger 38, carries out heat exchange at these heat exchanger 38 places, and the air through overregulating is sent into indoor R from air taking port 18.
Also have,, on the air entry 16 of the decorative panel 14 of air-conditioner 10, air cleaner 20 is housed as Fig. 2 and shown in Figure 3.
Action to this air-conditioner describes below.
After fan electromotor 24 in the main body 22 of Fig. 1 begins to rotate, turbofan 26 begins to rotate, so the air of indoor R is inhaled into from the air entry 16 of Fig. 2, purify by air cleaner 20, deliver to heat exchanger 38 places, carry out heat exchange at these heat exchanger 38 places, after this air taking port from four orientation passes out to indoor R.
Under this blue or green condition, by air entry 16 inhaled airs, because one jiao in main body 22 has dividing plate 28, just can near the discharge outlet 32 of draining pump 30, draining pump, indoor mechanical valve 60 etc., not spill, can guarantee to deliver to indoor R by the air taking port 18 in four orientation through the room air of heat exchange.
Like this, shown in the embodiment, compare the noise in the time of to reduce running as will be described with existing air-conditioner.
With reference to Fig. 4 and Fig. 6, the noise test data (Fig. 4) of this example are done one relatively with the noise test data (Fig. 6) of existing air-conditioner, can clearly be seen that from each figure the air-conditioner of this example is compared with existing air-conditioner, the noise during running has reduced about more than 2 decibels.That is to say that the air-conditioner noise of Fig. 4 is 36.1 decibels, the air-conditioner noise of Fig. 6 is 38.1 decibels.
This is to be made of straight line portion 29 and sweep 31,31 because of dividing plate 28, and straight line portion 29 is roughly the same with existing position, and sweep 31,31 is more outwardly-bent than the extended line of straight line portion 29, and this sweep is connected with tube sheet 49,49 respectively.
The result who carries out noise test with various actual air-conditioners shows that the distance between the tube sheet 49,49 of heat exchanger 38 at least is less for well.
In addition, if the distance between the tube sheet 49,49 is too little, draining pump 30 just can't be installed expeditiously, thick and fast in the outside that connects their dividing plate 28, so in the scope that does not influence noise, interior side-prominent for well with a part 29 heat exchanger 38 of dividing plate 28.
According to above-mentioned example, the part 29 of dividing plate 28 is roughly to be in line to extend, but might not be confined to this, and the interior side-prominent part of heat exchanger 38 also can be circular-arc, also can be triangle or the like.
Be to describe the present invention above, but the present invention is not limited to this example according to a kind of example.For example, in above-mentioned example, be the explanation that the air-conditioner 10 to four directions position blowing-type carries out, still, the present invention also goes for the air-conditioner of other kinds, for example two orientation blowing-type air-conditioners.
As mentioned above, according to the present invention, the distance between the heat exchanger tube sheet is less, and dividing plate is interior side-prominent around the part heat exchanger of draining pump, so the less disorder of air-flow that forms from fan, the noise during running can reduce than existing air-conditioner.
