Field of the Invention [0002] The present invention relates to an air conditioner installed, for example, embedded in a ceiling. 2. Description of the Related Art Generally, as shown in FIG. 6, a fan 2 is provided in a housing (hereinafter, referred to as a "unit body") 1 of an air conditioner, and has a substantially rectangular shape so as to surround the fan 2. And a tube plate 4 of the heat exchanger 3 is connected with a partition plate 5, and a drain pump is provided in a space 6 outside the heat exchanger 3 partitioned by the partition plate 5. One containing seven is known. In this type, indoor air sucked from the suction port 8 exchanges heat with the heat exchanger 3 and is blown out from the four-way outlet 9. The partition plate 5 is provided to prevent air from leaking from the vicinity of the drain pump 7, the mechanical valve 7a, and the like. [0003] However, the conventional air conditioner has a problem that noise is generated during operation due to turbulence of the wind discharged from the fan 2. Accordingly, an object of the present invention is to provide an air conditioner capable of reducing noise during operation in order to solve the above problems. [0007] To achieve the above object,
According to the first aspect of the present invention , one fan is provided in the housing of the air conditioner and a substantially rectangular shape surrounds the one fan.
And a heat exchanger formed by bending the heat exchanger into tubes. The tube plates of the heat exchanger are connected by a partition plate, and heat exchange is performed by the heat exchanger.
Air blown out from the four outlets
And, wherein one fan is directed on the axis of the fan from the center of the heat exchanger to the partition plate side in the longitudinal direction of the rectangular
Are arranged so as to be shifted by a predetermined distance . According to the present invention, since the axis of the fan is arranged so as to be shifted from the center of the heat exchanger toward the partition plate in the longitudinal direction by a predetermined distance , wind turbulence is reduced. In addition, noise during operation can be reduced. An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a bottom view showing a unit main body of an air conditioner according to the present invention, FIG. 2 is a diagram showing the unit main body and a decorative panel, and FIG.
FIG. 4 is a cross-sectional view showing a unit main body and a decorative panel. Referring to FIG. 3, reference numeral 10 denotes a ceiling-embedded air conditioner, which is suspended and fixed in a ceiling space 11 of a building 40. This air conditioner 10
It is a four-way blowout type air conditioner, and the unit body 2
2 and a decorative panel 14, a suction port 16 is opened at the center of the longitudinal axis of the decorative panel 14, and an outlet 18 is opened around the suction port 16 of the decorative panel 14. Building 40
, Four bolts 42 extend vertically downward, and hanging bolts 44 of the unit body 22 are fixed to these bolts 42. As shown in FIG. 2, in the unit body 22 of the air conditioner 10, a fan motor 24, a turbo fan 26, a heat exchanger 38 formed by being bent into a substantially rectangular shape so as to surround the fan motor 24, a turbo fan 26, and an electric device. The box 36 is accommodated. In the heat exchanger 38, the tube sheets 49, 49 are partitioned by a partition plate 28, and a space 56 outside the heat exchanger 38 partitioned by the partition plate 28 has a drain pump 30, a drain outlet 32, A refrigerant pipe 34 and the like are accommodated. The partition plate 28 prevents air from leaking during operation, and the presence of the partition plate 28 ensures that heat-exchanged air is blown out from the four outlets 18 into the room R. ing. According to this embodiment, as shown in FIG. 1, the heat exchanger 38 is bent in a substantially rectangular shape and is located so as to surround the turbo fan 26. Are arranged so as to be shifted from the center of the heat exchanger 38 to the partition plate 28 side. The axis of the turbo fan 26 refers to the axis of the output shaft of the fan motor 24, and the center of the heat exchanger 38 corresponds to the intersection of the lines L1 and L2, that is, the intersection of the longitudinal axis L1 and the transverse axis L2. Let's say the intersection. As shown in FIG. 3, an air filter 20 is provided in the suction port 16 of the decorative panel 14 of the air conditioner 10. Next, the operation of the air conditioner will be described.
1 to 3, when the fan motor 24 in the main body casing 22 is operated, the turbo fan 26 rotates, so that the air in the room R is sucked through the suction port 16, and after being cleaned by the air filter 20, After being sent to the exchanger 38 and subjected to heat exchange in the heat exchanger 38, the air is blown into the room R from the four outlets 18. In this case, the room air sucked from the suction port 16 and subjected to heat exchange exchanges with the drain pump 3 due to the presence of the partition plate 28 located at the corner of the unit body 22.
0, it does not leak to the vicinity of the drain outlet 32, the indoor mechanical valve 60, etc., and is almost certainly blown into the room R through the four outlets 18. According to this embodiment, the turbo fan 2
Since the axis of the shaft 6 is shifted from the center of the heat exchanger 38 toward the partition plate 28 by the distance L3, the noise during operation is reduced as compared with the conventional one as shown in the embodiment described later. The distance L3 is desirably, for example, about 100 mm, but differs depending on the size of the unit body 22. However, it has been found that the bending shape of the heat exchanger 38 is not so affected. For example, the heat exchanger 38
The bent shape of a square or a rectangle,
It may be oval or circular. In short, according to this embodiment, it is important to shift the axis of the turbo fan 26 with respect to the center of the heat exchanger 38, and the direction of shifting the axis of the turbo fan 26 may be in any direction. There is no limitation. In the embodiment shown in FIG. 1, the axis of the turbo fan 26 is shifted from the center of the heat exchanger 38 toward the partition plate 28, but shifting in this direction is only desirable for noise reduction. It has been found that the displacement may be in the direction opposite to the plate 28. However, in this case, it has been found that the effect of noise reduction is not so large as compared with the case of shifting to the partition plate 28 side. According to this, since the vortex and turbulence of the wind discharged from the turbo fan 26 can be reduced, the operation noise can be reduced as compared with the conventional one. Referring to FIGS. 4 and 5, noise test data (FIG. 4) according to this embodiment is compared with noise test data (FIG. 5) according to the prior art. As is clear from FIG. 2, the device according to this embodiment has a lower noise during operation than the conventional device at about 2 dB. That is, in FIG. 4, the noise is 48.3 dB, and in FIG. 5, the noise is 50.3 dB. The size of the actual machine used in the noise test is shown in FIG. 1 with the dimensions of the unit body 22 in the direction of the longitudinal axis L1; H1 = 1050 mm; the dimensions of the heat exchanger 38; H2 = 900 mm; The dimension of the unit body 22 in the direction of the short axis L2; W1 = 760 mm; the dimension of the heat exchanger 38; W2 = 610 mm; In short, according to this embodiment, as a result of performing various noise tests, regardless of the bending shape of the heat exchanger 38, if the axis is shifted in any direction, the operation noise Has been found to be reduced. As described above, the present invention has been described in accordance with one embodiment, but the present invention is not limited to this embodiment. For example, in the above-described embodiment, the four-way air conditioner 10 is described. However, the present invention is applied to other types of air conditioners, for example, two-way air conditioners. Applicable. As described above, according to the present invention, the heat exchanger is located so as to be bent so as to surround the fan, and the axis of the fan is positioned in the longitudinal direction from the center of the heat exchanger. To
Since it is arranged so as to be shifted by a predetermined distance toward the partition plate side, it is possible to reduce the vortex and turbulence of the wind discharged from the fan, and it is possible to reduce the noise during operation.
