The refrigerant condensed through the first heat exchanger 18A and the second heat exchanger 18B flows out of the outdoor unit 1 and flows into the indoor unit 200 shown in FIG. The refrigerant flowing into the indoor unit 200 is expanded by the expansion device 204 and flows through the use side heat exchanger 202. The refrigerant that has flowed through the use-side heat exchanger 202 and has evaporated flows out of the indoor unit 200 and flows into the outdoor unit 1 shown in FIG. The refrigerant that has flowed into the outdoor unit 1 is stored in the accumulator 26 via the first flow path switching device 14A. The refrigerant stored in the accumulator 26 is sucked into the compressor 12 and compressed again.

[Heating operation]
Next, an example of the operation of the outdoor unit 1 and the indoor unit 200 during the heating operation will be described. When performing the heating operation, the first flow path switching device 14A and the second flow path switching device 14B illustrated in FIG. 1 are connected to each other as indicated by a solid line.

FIG. 7 is a diagram schematically illustrating a cross section of a portion in which the unit is accommodated, FIG. 7 is a diagram illustrating a state of mounting the mounting member illustrated in FIG. 6 to the main body case, and FIG. It is the figure which expanded the fan motor and attachment member as described in. A specific structure of the outdoor unit 1 according to this embodiment will be described with reference to FIGS.

  As shown in FIGS. 3 and 4, the outdoor unit 1 according to this embodiment has a main body case 101, and a compressor 12, a flow path switching device 14, and a decompression device 16 are provided inside the main body case 101. The heat exchanger 18 and the accumulator 26 are accommodated. The main body case 101 has, for example, a substantially rectangular parallelepiped shape, and an air intake portion 104 that sucks air to the side is formed, and a blowout portion 109 that blows air upward is formed. That is, the outdoor unit 1 according to this embodiment blows out air sucked from the side from above.

  The lower part of the main body case 101 is covered with an open / close panel 102A, a left side lower panel 102B, a rear lower panel 102C, and a right side lower panel 102D, and forms a machine room 103 in which, for example, the compressor 12 is accommodated. Yes. The open / close panel 102 </ b> A, the left side lower panel 102 </ b> B, the back lower panel 102 </ b> C, and the right side lower panel 102 </ b> D are substantially flat members and constitute the outer shell of the lower part of the outdoor unit 1. The open / close panel 102A is disposed at the lower part of the front surface of the outdoor unit 1, the lower left panel 102B is disposed at the lower part of the left side surface of the outdoor unit 1, and the rear lower panel 102C is the lower part of the rear surface of the outdoor unit 1. The right side lower panel 102D is arranged at the lower part of the right side of the outdoor unit 1. 3 is attached to the main body case 101 so as to be freely opened and closed. By opening the open / close panel 102A, maintenance and the like of the compressor 12 and the electrical component box (not shown) disposed inside the main body case 101 can be performed. The outdoor unit 1 in the example of this embodiment may be one in which all or a part of the open / close panel 102A, the left side lower panel 102B, the rear lower panel 102C, and the right side lower panel 102D is omitted. Good.

  As shown in FIGS. 3 to 5, a heat exchange chamber 105 in which the heat exchanger 18 is accommodated is formed in the upper part of the machine chamber 103 of the main body case 101. The main body case 101 of the example of this embodiment has an intake portion 104 that sucks air around the entire circumference of the main body case 101. That is, the main body case 101 includes a front intake portion 104A that sucks air from the front surface, a left side intake portion 104B that sucks air from the left side surface, a rear intake portion 104C that sucks air from the rear surface, and a right side surface that sucks air from the right side surface. And an intake portion 104D. For example, each of the front intake section 104A, the left side intake section 104B, the rear intake section 104C, and the right side intake section 104D is provided with a panel having a plurality of air intake ports through which air passes. The outdoor unit 1 according to this embodiment may be a frame-type outdoor unit from which a panel is omitted.

  As shown in FIGS. 3 and 4, the upper portion of the heat exchange chamber 105 of the main body case 101 forms a bell mouth portion 106. The bell mouth portion 106 has a cylindrical shape, and a blowout portion 109 that blows air upward is formed. As shown in FIG. 6, the fan 22 is housed inside the bell mouth portion 106. A fan guard portion 110 that covers the top of the fan 22 is attached to the bell mouth portion 106. The outer periphery of the fan guard part 110 is fixed to the bell mouth part 106.

  When the fan 22 operates, air is sucked in from the front intake unit 104A, the left side intake unit 104B, the rear intake unit 104C, and the right side intake unit 104D shown in FIGS. The sucked air passes through the heat exchanger 18 and is subjected to heat exchange, and is then exhausted from the blowing unit 109 illustrated in FIGS. 3 and 4.

  As shown in FIG. 5, the heat exchanger 18 of the example of this embodiment has four heat exchange parts that exchange heat with air sucked from the intake parts 104 formed on the four side surfaces. That is, the air taken in from the front intake portion 104A passes through the portion of the first heat exchanger 18A that faces the front intake portion 104A and is heat-exchanged. The air taken in from the left side air intake portion 104B passes through a portion facing the left side air intake portion 104B of the second heat exchanger 18B and is heat exchanged. The air taken in from the back surface intake portion 104C passes through a portion of the second heat exchanger 18B facing the back surface intake portion 104C, and is heat-exchanged. The air taken in from the right side intake portion 104D passes through a portion of the first heat exchanger 18A facing the right side intake portion 104D and is heat-exchanged. Then, the air that has passed through the heat exchanger 18 and has undergone heat exchange is blown out from the blowing unit 109 illustrated in FIGS. 3 and 4. In the example of this embodiment, aerodynamic performance is improved because air is uniformly sucked from the entire circumferential direction of the front surface, both side surfaces, and the back surface of the outdoor unit 1. In the outdoor unit 1 of the example of this embodiment, since the aerodynamic performance is improved, the electric power for driving the fan is reduced, and further, the noise when the fan is driven is reduced.

[Installing the fan unit]
As shown in FIG. 6, the fan unit 24 includes a fan 22 and a fan motor 23. The fan unit 24 is attached to the main body case 101 by an attachment member 90. As shown in FIGS. 6 and 7, the attachment member 90 includes a fixing portion 92 fixed to the main body case 101, and a unit holding portion 94 that holds the fan motor 23 of the fan unit 24. The fixing portions 92 are formed on both sides of the unit holding portion 94 and are fixed to the main body case 101. That is, the fixing portion 92 is fixed to the front-side frame 86 at the upper front side of the main body case 101 and the rear-side frame 87 at the upper rear side of the main body case 101. The fixing portion 92 may be fixed to the left side frame of the main body case 101 and the right side frame of the main body case 101. As shown in FIGS. 7 and 8, the fixing portion 92 and the unit holding portion 94 are connected by a connecting portion 93, and the unit holding portion 94 is recessed downward from the fixing portion 92. That is, the attachment member 90 has a shape in which the unit holding portion 94 protrudes downward from the fixing portion 92. For example, the attachment member 90 is formed by bending or the like, and the fixing portion 92, the connecting portion 93, and the unit holding portion 94 are integrally formed. The fan motor 23 is fixed to a unit holding portion 94 that is recessed downward from the fixing portion 92.

  The fan motor 23 has a drive shaft 23A that protrudes upward. As shown in FIG. 6, the fan 22 is attached to a drive shaft 23 </ b> A of the fan motor 23. The fan 22 has a central boss portion 22A and a wing portion 22B formed around the boss portion 22A. The upper part of the boss part 22A is recessed below the top part of the wing part 22B, and the risk of contact between the fan guard part 110 and the fan 22 is reduced. This is because the outer periphery of the fan guard part 110 is fixed to the bell mouth part 106. Therefore, as indicated by the imaginary line 110A, when a force is applied to the fan guard part 110, the central part of the fan guard part 110 is most easily bent. In the example of this embodiment, since the central boss portion 22A of the fan 22 is recessed downward from the wing portion 22B, the possibility of contact between the fan guard portion 110 and the fan 22 is suppressed.

  FIG. 9 is a diagram for explaining the relationship between the radial position of the fan and the speed of intake of the fan. As shown in FIG. 9, on the suction side of the fan 22, the suction speed is slow on the side near the boss 22A of the wing 22B, and the suction speed is fast on the side far from the boss 22A of the wing 22B. Accordingly, the intake air loss of the fan 22 can be reduced by increasing the distance between the blade portion 22B and the attachment member 90 on the outer side of the blade portion 22B. As shown in FIG. 6, in the example of this embodiment, the connecting position of the fixing portion 92 and the connecting portion 93 is a straight line connecting the connecting portion between the boss portion 22A and the wing portion 22B and the end portion of the wing portion 22B. It is located outward from the middle position. That is, the attachment member 90 has a shape that begins to bend downward from the fixed portion 92 outside the intermediate position of the wing portion 22B. For example, the connecting portion 93 has a shape bent vertically downward from the fixed portion 92, but the connecting portion 93 has a shape bent obliquely downward from the fixed portion 92. Also good. In the example of this embodiment, the distance between the lower portion of the wing portion 22B and the attachment member 90 is the length between the lower portion of the wing portion 22B and the unit holding portion 94 on the outer side of the wing portion 22B. Therefore, the loss of intake air from the fan 22 can be reduced. The connecting position of the fixing portion 92 and the connecting portion 93 is positioned outside the intermediate position of the straight line connecting the connecting portion between the boss portion 22A and the wing portion 22B and the end portion of the wing portion 22B. Although the loss of the intake air of the fan 22 can be reduced, more preferably, the connecting position of the fixing portion 92 and the connecting portion 93 is positioned outward from the end portion of the wing portion 22B. 22 intake air loss can be reduced.

[Comparison with comparative example]
10 is a diagram of Comparative Example 1 which is a comparative example of FIG. 5, FIG. 11 is a diagram of Comparative Example 2 which is a comparative example of FIG. 6, and FIG. It is the figure which compared the outdoor unit of Embodiment 1, the comparative example 1, and the comparative example 2. FIG. In FIG. 12, A indicates the intake air loss of the fan itself, B indicates the intake air loss of the fan generated by the mounting member, C indicates the intake air loss generated by the arrangement of the heat exchanger, and D is generated during exhaust. Exhaust loss is shown.

  As shown in FIG. 10, in Comparative Example 1, the heat exchanger 180 disposed in the heat exchange chamber 150 has a twice-bent shape. In the comparative example 1, the air sucked from the three side surfaces of the side surface 140A, the side surface 140B, and the side surface 140C is configured to pass through the heat exchanger 180. In Comparative Example 1, the air intake is not uniformly sucked from the circumferential direction of the heat exchange chamber 150, so that the intake balance is poor, and the intake loss C due to the arrangement of the heat exchanger is large as shown in FIG. Compared with Comparative Example 1, the outdoor unit 1 of this embodiment has a configuration in which air is uniformly sucked from the entire circumference of the front surface, both side surfaces, and the back surface as shown in FIG. The intake loss C due to the arrangement of the vessel is improved.

  As shown in FIG. 11, in Comparative Example 2, a fan unit 240 having a fan 220 and a fan motor 230 is attached to the main body case by a linear attachment member 190. In Comparative Example 2, the boss 220A at the center of the fan 220 is positioned above the wing 220B and is closest to the fan guard 111. As shown by the phantom line 111A, the fan guard part 111 is most easily bent at the center. Therefore, in Comparative Example 2, there is an increased risk of contact between the fan guard part 111 and the boss part 220A. Compared to Comparative Example 2, the outdoor unit 1 of this embodiment has a boss portion 22A that is recessed downward from the wing portion 22B, as shown in FIG. The risk of contact is reduced.

  Further, as shown in FIG. 11, in Comparative Example 2, the boss 220A of the fan 220 is positioned above the wing 220B. Therefore, in order to obtain aerodynamic characteristics, the lower part of the wing 220B is downward. It protrudes greatly, and the lower part of the wing part 220B and the attachment member 190 are close to each other. In Comparative Example 2, since the lower portion of the wing portion 220B and the attachment member 190 are close to each other, the intake of the fan 220 is hindered, and as shown in FIG. 12, the intake loss of the fan generated by the attachment member B is larger. Compared to Comparative Example 2, in the outdoor unit 1 of this embodiment, as shown in FIG. 6, the boss portion 22A is recessed downward from the upper portion of the wing portion 22B, and the wing portion 22B is the boss portion 22A. It is also formed above. In the outdoor unit 1 of this embodiment, unlike Comparative Example 2, there is no need to project the lower part of the wing part 22B greatly downward in order to obtain aerodynamic characteristics. Therefore, in the outdoor unit 1 of this embodiment, since the distance between the lower portion of the wing portion 22B and the mounting member 90 can be increased, the fan intake loss generated by the mounting member as shown in FIG. B is reduced.

  In addition, in the outdoor unit in which air is not uniformly sucked from the circumferential direction of the heat exchange chamber 150 as in Comparative Example 1 described in FIG. 10, as shown in FIG. 12, the intake loss due to the arrangement of the heat exchanger C is large, and the fan intake loss B generated by the mounting member is relatively small. Therefore, in the outdoor unit like the comparative example 1, the effect obtained by improving the fan intake loss B generated by the mounting member is small. However, as shown in FIG. 5, in the outdoor unit in which air is uniformly sucked from the entire circumference of the front surface, both side surfaces, and the back surface, as shown in FIG. 12, the influence of the fan intake loss B generated by the mounting member Therefore, the effect of reducing the fan intake loss B generated by the mounting member becomes significant.

  As described above, in the outdoor unit 1 of this embodiment, the fan unit 24 is attached to the main body case 101 by the attachment member 90. The attachment member 90 includes a fixing portion 92 fixed to the main body case and a unit holding portion 94 that holds the fan unit 24, and the unit holding portion 94 is recessed from the fixing portion 92. In this embodiment, since the fan unit 24 is held by the unit holding part 94 that is recessed downward from the fixing part 92, the outdoor unit 1 that is downsized in the height direction can be obtained. Further, the center of gravity of the outdoor unit 1 is lowered by holding the fan unit 24 in the unit holding portion 94 that is recessed downward from the fixing portion 92.

  Further, in the outdoor unit 1 of this embodiment, the boss 22A at the center of the fan 22 is recessed downward from the top of the wing 22B. The fan guard part 111 covering the upper side of the fan 22 has an outer peripheral part fixed to the bell mouth part 106 of the main body case 101, so that the center part of the fan guard part 111 is easily bent. In the outdoor unit 1 of this embodiment, since the central boss portion 22A of the fan 22 is recessed, the possibility of contact between the fan 22 and the fan guard portion 111 is suppressed, and safety is improved.

  In the outdoor unit 1 of this embodiment, the boss portion 22A of the fan 22 is recessed downward from the top of the wing portion 22B, and the wing portion 22B includes a portion formed above the boss portion 22A. Yes. Therefore, in this embodiment, since the lower part of the wing part 22B can be positioned upward, the distance between the lower part of the wing part 22B and the attachment member 90 can be increased. Therefore, in this embodiment, the intake loss of the fan 22 generated by the mounting member 90 is reduced, and the noise reduction is achieved by further reducing the intake loss.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. That is, the configuration of the above embodiment may be improved as appropriate, or at least a part of the configuration may be replaced with another configuration. Further, the configuration requirements that are not particularly limited with respect to the arrangement are not limited to the arrangement disclosed in the embodiment, and can be arranged at a position where the function can be achieved.
