Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the structure of Patent Document 1, when the second electrical component support is moved, the wiring connected to the second electrical component support (hereinafter referred to as the cable) moves together with the second electrical component support. Therefore, when the second electrical component support is returned to its original position, this cable comes close to a cable carrying electromagnetic noise, for example, a switching power supply supported by the first electrical component support. As a result, electromagnetic noise is superimposed on the cable that moved together with the second electrical component support, and there is a risk that electromagnetic noise may leak from this cable to the outside of the outdoor unit. In addition, electromagnetic noise propagated through the cable that moved together with the second electrical component support may be superimposed on other cables installed in the machine room, potentially causing the outdoor unit to malfunction.

[0006] The disclosed technology was developed in view of the above, and aims to provide an outdoor unit for an air conditioner that ensures workability inside the machine room and suppresses the superposition of electromagnetic noise on cables connected to the electrical component support section. [Means for solving the problem]

The end of the first electrical component support part on the second surface side and the end of the second electrical component support part on the first surface side are arranged adjacent to each other.

[Modes for carrying out the invention]

[0010] The following describes in detail, with reference to the drawings, an embodiment of the outdoor unit of the air conditioning system disclosed in this application. However, the following embodiment does not limit the outdoor unit of the air conditioning system disclosed in this application. [Examples]

[0011] (Outdoor unit) Figure 1 is a schematic perspective view of the outdoor unit of the embodiment. The outdoor unit 1 of the embodiment is connected to a plurality of indoor units 2 that constitute an air conditioning system, as an example, and constitutes a so-called multi-air conditioner. As shown in Figure 1, the outdoor unit 1 comprises a heat exchanger 4, a compressor 6, and a housing 7 that houses the heat exchanger 4 and the compressor 6. The housing 7 has a heat exchange chamber 8 in which the heat exchanger 4 is provided, and a machine room 9 in which various components such as the compressor 6 and piping 18 that constitute a refrigerant circuit through which the refrigerant circulates are provided, and the heat exchange chamber 8 and the machine room 9 are separated by a partition plate 10. The heat exchange chamber 8 is provided with a fan 5 that takes in outside air and blows it to the heat exchanger 4.

[0012] The enclosure 7 is formed in the shape of a rectangular box. In the drawing, the width direction of the enclosure 7 is shown as the X direction, the depth direction of the enclosure 7 is shown as the Y direction, and the height direction of the enclosure 7 is shown as the Z direction. The enclosure 7 has a first surface, which is a front surface 7F that is aligned with the XZ plane, a second surface, which is a side surface 7S that is aligned with the YZ plane, and a rear surface 7R that is opposite the front surface 7F.

[0013] For example, the front section 7F of the housing 7 is provided with an air outlet 7a for discharging air that has passed through the heat exchanger 4. The side section 7S of the housing 7 is provided with a removable side panel 7b, and by removing only the side panel 7b from the housing 7, it is possible to perform maintenance inside the machine room 9. The rear section 7R of the housing 7 is provided with an intake port (not shown) for drawing air into the heat exchanger 4.

[0014] (mechanical room) FIG. 2 is a perspective view schematically showing the machine room 9 of the outdoor unit 1 of the embodiment. FIG. 3 is a view of the first electrical component support portion 16 and the second electrical component support portion 17 in the outdoor unit 1 of the embodiment as seen from the front surface portion 7F side of the housing 7. FIG. 4 is a view of the first electrical component support portion 16 and the second electrical component support portion 17 in the outdoor unit 1 of the embodiment as seen from the rear surface portion 7R side of the housing 7.

[0015] As shown in FIGS. 2, 3, and 4, in the machine room 9, there are housed a power terminal block 12 connected to an external AC power supply 11, a first high-voltage cable 14 having one end connected to the power terminal block 12, a first substrate 15 to which the other end of the first high-voltage cable 14 is connected and to which a high voltage is supplied from the external AC power supply 11 via the power terminal block 12 and the first high-voltage cable 14, a first electrical component support portion 16 that supports the first substrate 15, and a second electrical component support portion 17 that supports the power terminal block 12.

[0016] (First Electrical Component Support Portion and Second Electrical Component Support Portion) The first electrical component support portion 16 is arranged along the front surface portion 7F of the housing 7. The second electrical component support portion 17 is arranged along the side surface portion 7S of the housing 7 adjacent to the front surface portion 7F. Also, an end portion 16a on the side surface portion 7S side in the first electrical component support portion 16 and an end portion 17a on the front surface portion 7F side in the second electrical component support portion 17 are arranged adjacent to each other. [[ID=II]]

[0017] The end portion 17a of the second electrical component support portion 17 is provided so as to be movable around a moving axis A along the end portion 16a of the first electrical component support portion 16. The moving axis A is provided along the front surface portion 7F and the side surface portion 7S of the housing 7, that is, along the Z direction which is the height direction of the housing 7. Details of the moving axis A will be described later.

[0018] (Closed Position and Open Position of the First Electrical Component Support Portion) FIG. 5 is a perspective view showing a state in which the second electrical component support portion 17 is located at the closed position P1 in the embodiment. FIG. 6 is a perspective view showing a state in which the second electrical component support portion 17 is located at the closed position P1 in the embodiment. FIG. 7 is a perspective view showing a state in which the second electrical component support portion 17 is located at the open position P2 in the embodiment.

[0019] As shown in Figures 5, 6, and 7, when the machine room 9 is viewed from the side portion 7S of the housing 7, the second electrical component support 17 moves to a closed position P1 (see Figures 5 and 6) where it closes the internal space B enclosed by the first electrical component support 16 and the second electrical component support 17 from the side portion 7S, and to an open position P2 (see Figures 3 and 7) where the end 17b of the second electrical component support 17 opposite to the movable axis A is located outside the internal space B, away from the internal space B, and the side portion 7S of the internal space B is open. The internal space B is located between the first electrical component support 16 and the rear portion 7R of the housing 7, and contains components such as the compressor 6 and piping 18 connected to the compressor 6.

[0020] As an example, the second electrical component support part 17 is aligned along the side portion 7S when in the closed position P1 and aligned along the front portion 7F when in the open position P2. When the second electrical component support part 17 is viewed from the side portion 7S, in the closed position P1, the second electrical component support part 17 is positioned to cover a part of the internal space B. The embodiment is not limited to a structure in which the second electrical component support part 17 moves from the closed position P1 to the open position P2, that is, a structure in which it moves about 90 degrees around the movement axis A from the closed position P1 to the open position P2, but the second electrical component support part 17 may be structured to move about 180 degrees around the movement axis A from the closed position P1, for example.

[0021] As the second electrical component support section 17 is provided to be movable between a closed position P1 and an open position P2, when performing maintenance work in the internal space B of the machine room 9 from the side portion 7S of the housing 7, only the side panel 7b can be removed from the side portion 7S, and the second electrical component support section 17 covering the internal space B can be easily moved, allowing easy access to the internal space B. This makes maintenance work in the internal space B easier.

[0022] (Axis of movement) In this disclosure, as an example, the movable axis A refers to a virtual axis passing through the protruding claws 27a of a pair of engaging pieces 27 (see Figures 5, 6, and 8) formed on the end 17a of the second electrical component support 17. However, the structure is not limited to this, and a pivot shaft (not shown), which is a component, may be provided as the movable axis A at the end 17a of the second electrical component support 17, and the end 17a of the second electrical component support 17 may be rotatably supported at the end 16a of the first electrical component support 16 via the pivot shaft. Furthermore, the movable axis A is not limited to being provided at the end 17a of the second electrical component support 17, but may also be provided at the end 16a of the first electrical component support 16.

[0023] Furthermore, in this embodiment, the movable axis A is provided at the end 17a of the second electrical component support 17, but the position of the movable axis A in the Y direction along the side portion 7S is not limited. For example, the movable axis A may be provided in the center of the second electrical component support 17 in the Y direction, and a part of the rear portion 7R side of the second electrical component support 17 may partially move relative to the movable axis A. In other words, it is sufficient that at least a part of the second electrical component support 17 is moved around the movable axis A.

[0024] In this disclosure, the configuration in which the end portion 17a of the second electrical component support portion 17 is provided to be movable around the movable axis A includes, for example, a configuration in which the end portion 17a of the second electrical component support portion 17 is temporarily removed from the end portion 16a of the first electrical component support portion 16, the second electrical component support portion 17 is moved around the movable axis A, and then the end portion 17a of the second electrical component support portion 17 is attached to the end portion 16a of the first electrical component support portion 16, and a configuration in which the end portion 17a of the second electrical component support portion 17 is rotated around the movable axis A relative to the end portion 16a of the first electrical component support portion 16.

[0025] The first electrical component support section 16 has a first support frame 21 made of a metal plate, and the upper end surface 21a of the first support frame 21 is fixed to the partition plate 10 along the X direction. The second electrical component support section 17 has a second support frame 22 made of a metal plate, and the second support frame 22 is supported so as to be movable around the movable axis A relative to the first support frame 21.

[0026] Figure 8 is an enlarged view showing the first notch groove 26 of the first electrical component support part 16 in the embodiment. As shown in Figures 5, 6 and 8, a pair of first notch grooves 26 are formed at intervals in the vertical Z direction at the end 16a of the first electrical component support part 16 formed by the first support frame 21. These grooves serve as a rotatable support part that allows the end 17a of the second electrical component support part 17 to rotate around the movable axis A and detachably support the second electrical component support part 17.

[0027] As shown in Figures 5 and 6, a pair of engaging pieces 27 are formed at the end 17a of the second electrical component support section 17, which is formed by the second support frame 22, and are spaced apart in the vertical Z direction. These engaging pieces engage with the first notched groove 26 of the end 16a of the first electrical component support section 16. The engaging pieces 27 are formed extending toward the end 16a of the first electrical component support section 16, and a protruding claw 27a that engages with the first notched groove 26 is formed at the tip of the engaging piece 27.

[0028] In the closed position P1 and the open position P2, the protruding claw 27a of the engaging piece 27 of the second electrical component support 17 engages with the first notched groove 26 of the end portion 16a of the first electrical component support 16. In this embodiment, the second support frame 22 of the second electrical component support 17 is fixed inside the machine room 9 by fixing screws (not shown) when it is in the closed position P1.

[0029] Furthermore, as shown in Figure 8, the end portion 16a of the first electrical component support portion 16 is provided with a second notch groove 28 adjacent to the first notch groove 26. This second notch groove 28 serves as a fixed support portion that supports the second electrical component support portion 17, which has been removed from the first notch groove 26, and fixes it in the open position P2. The second notch groove 28 engages with the engaging piece 27 of the end portion 17a of the second electrical component support portion 17, which has been moved to the open position P2, thereby restricting the movement of the second electrical component support portion 17, which is located in the open position P2, around the movable axis A. This allows the second electrical component support portion 17 to be easily fixed in the open position P2. As a result, it is possible to prevent the second electrical component support portion 17 from accidentally moving from the open position P2 to the closed position P1, and thus maintenance work in the internal space B can be performed stably. Furthermore, the engaging piece 27 of the second electrical component support 17 may engage with the first notch groove 26 without using the second notch groove 28 when the second electrical component support 17 is moved from the closed position P1 to the open position P2.

[0030] The first circuit board 15, provided on the first electrical component support section 16, has a control circuit for controlling the outdoor unit 1. As shown in Figures 2 and 3, a mounting surface 15a, on the side of the first electrical component support section 16 facing the front section 7F, is arranged along the front section 7F, on which various electrical components described later are mounted.

[0031] (Connection structure of the first high-voltage cable) As shown in Figures 3, 5, and 6, the first circuit board 15 has a first connection portion 15c, which is a connection terminal to which the first high-voltage cable 14 is connected. The first connection portion 15c is located on the side of the movable axis A on the mounting surface 15a of the first circuit board 15 in the X direction along the front portion 7F. Here, being located on the side of the movable axis A on the first circuit board 15 means being located at the end 15b on the side of the movable axis A than the center of the first circuit board 15 in the X direction. This allows the length of the first high-voltage cable 14 to be shortened, so that the portion of the first high-voltage cable 14 that moves together with the second electrical component support portion 17 when the second electrical component support portion 17 moves around the movable axis A is shortened. Therefore, when the second electrical component support portion 17 is moved and fixed in the closed position P1, it is suppressed that the first high-voltage cable 14 will be routed in a way that was not originally intended. This prevents the first high-voltage cable 14 from coming close to electrical components that emit electromagnetic noise or other cables that propagate electromagnetic noise (for example, the cable connected to the compressor 6). As a result, the superposition of electromagnetic noise from other cables onto the first high-voltage cable 14 is suppressed. Furthermore, by suppressing the superposition of electromagnetic noise onto the first high-voltage cable 14, the propagation of electromagnetic noise from the first high-voltage cable 14 to other cables is suppressed.

[0032] Although not shown in the diagram, the first connection portion 15c may be located on the side of the moving axis A on the first circuit board 15, and the position of the power terminal block 12 on the second electrical component support portion 17 may be located on the side of the moving axis A on the second electrical component support portion 17 in the Y direction along the side portion 7S. This allows the length of the first high-voltage cable 14 to be further shortened, thereby further suppressing the first high-voltage cable 14, which moves together with the second electrical component support portion 17 that moves around the moving axis A, from coming close to electrical components that emit electromagnetic noise or other cables that propagate electromagnetic noise. In other words, by having at least one of the position of the first connection portion 15c on the first circuit board 15 and the position of the power terminal block 12 on the second electrical component support portion 17 located on the side of the moving axis A, the effect of suppressing the superposition of electromagnetic noise on the first high-voltage cable 14 and the propagation of electromagnetic noise from the first high-voltage cable 14 to other cables can be obtained.

[0033] Furthermore, as shown in Figure 4, the first electrical component support section 16 has a step-down section 31 that steps down the high voltage supplied to the first circuit board 15 from the external AC power supply 11. As shown in Figures 3 and 5, on the mounting surface 15a of the first circuit board 15, a high-voltage circuit 33A is arranged on the side of the movable axis A in the X direction along the front section 7F, to which high voltage is supplied from the external AC power supply 11 via the first high-voltage cable 14. On the mounting surface 15a of the first circuit board 15, on the side opposite to the movable axis A, a low-voltage circuit 33B is arranged to which low voltage stepped down by the step-down section 31 is supplied. In other words, the high-voltage circuit 33A and the low-voltage circuit 33B are provided side by side on the mounting surface 15a of the first circuit board 15 in the X direction along the front section 7F.

[0034] As shown in Figure 3, the end 15b of the first circuit board 15 on the movable axis A side of the high-voltage circuit 33A is provided with a first connection part 15c to which the first high-voltage cable 14 is connected. Similarly, the end of the high-voltage circuit 33A on the movable axis A side is provided with a fourth connection part 15e to which the second high-voltage cable 38, which will be described later, is connected. In addition, electrical components such as X capacitor 33a, Y capacitor 33b, common mode choke coil 33c, arrester 33d, varistor 33e, and fuse 33f, which constitute the outdoor unit power supply filter circuit F1 and the indoor unit power supply filter circuit F2, are mounted on the high-voltage circuit 33A.

[0035] A third connection point 15d is provided in the center of the low-voltage circuit 33B, to which a low-voltage cable 37, described later, is connected. Electrical components such as an IC (Integrated Circuit) chip 33g, a diode 33h, and a transistor 33k are mounted on the low-voltage circuit 33B.

[0036] Furthermore, as shown in Figures 3 and 5, the second electrical component support section 17 includes a second circuit board 35 to which a low voltage is supplied from the low-voltage circuit 33B of the first circuit board 15, and a plurality of indoor unit terminal blocks 36 that supply power to each indoor unit 2.

[0037] The second circuit board 35 is a maintenance circuit board having an adjustment section 35a for making various settings and adjustments when performing various maintenance work on the outdoor unit 1. The second electrical component support section 17 has an upper section 17U, a middle section 17M, and a lower section 17L arranged in the vertical Z direction. The upper section 17U, middle section 17M, and lower section 17L have support surfaces that are inclined such that when the second electrical component support section 17 is in the closed position P1, the side opposite to the internal space B is located lower than the internal space B, allowing the low-voltage cable 37, which will be described later and is connected to the second circuit board 35, to be smoothly pulled out from above the second electrical component support section 17.

[0038] The second circuit board 35 is located on the side of the movable axis A in the upper part 17U of the second electrical component support section 17. The power terminal block 12 of the second electrical component support section 17 is located on the opposite side of the movable axis A in the upper part 17U of the second electrical component support section 17, that is, on the rear surface 7R side when the second electrical component support section 17 is in the closed position P1.

[0039] This ensures a large distance between the power terminal block 12 and the first circuit board 15 of the first electrical component support section 16. Generally, the first high-voltage cable 14 connected to the power terminal block 12, which is connected to the external AC power supply 11, has a larger current value than the low-voltage cable 37 described later, so it tends to have a larger outer diameter, is less flexible, and is difficult to route. Therefore, even when using the first high-voltage cable 14, which is less flexible, the longer distance to the first circuit board 15 allows for a gentler curve when routing the first high-voltage cable 14 to avoid obstacles, thereby reducing the force applied to the first high-voltage cable 14. This makes it easier to route and connect the first high-voltage cable 14. In addition, the force applied to the first high-voltage cable 14 is also reduced when the second electrical component support section 17 is moved, thus preventing damage to the first high-voltage cable 14.

[0040] Multiple indoor unit terminal blocks 36 are located in the middle section 17M and the lower section 17L of the second electrical component support section 17. The indoor unit terminal blocks 36 are connected to the high-voltage circuit 33A of the first circuit board 15 via a second high-voltage cable 38, which will be described later. In addition, a supply cable (not shown) is connected to the indoor unit terminal blocks 36, and the supply cable is routed downward from the second electrical component support section 17 towards the side section 7S.

[0041] Furthermore, the machine room 9 houses a low-voltage cable 37 that connects the low-voltage circuit 33B of the first circuit board 15 to the second circuit board 35, and a second high-voltage cable 38 that sends high voltage from the first circuit board 15 to the second electrical component support section 17.

[0042] One end of the low-voltage cable 37 is connected to the third connection part 15d, which is a connection terminal located in the center of the low-voltage circuit 33B on the first circuit board 15, and the other end is connected to the second connection part 35c on the second circuit board 35, which will be described later.

[0043] Generally, the low-voltage cable 37 has a smaller outer diameter and is more prone to bending than the first high-voltage cable 14, etc., because it has a smaller current value. Also, when the second electrical component support 17 is moved around the movable axis A, the further the position of the end of the low-voltage cable 37 connected to the second electrical component support 17 is from the movable axis A, the greater the movement of the second electrical component support 17. Taking these points into consideration, in this embodiment, the low-voltage circuit 33B to which the flexible low-voltage cable 37 is connected is positioned on the first circuit board 15 at a position far from the movable axis A, that is, on the opposite side from the movable axis A. This allows the second electrical component support 17 to move smoothly without being hindered by the low-voltage cable 37, and makes it easy to access the internal space B. This improves the workability of maintenance performed in the internal space B. In addition, by positioning the low-voltage circuit 33B far from the movable axis A on the first substrate 15, space can be secured on the movable axis A side, making it possible to position the high-voltage circuit 33A, to which the first high-voltage cable 14, which is difficult to route, is connected, on the movable axis A side.

[0044] The second circuit board 35 has a second connection portion 35c, which is a connection terminal to which a low-voltage cable 37 is connected. The second connection portion 35c is located at the upper end of the second circuit board 35 on the internal space B side, which is supported by the upper portion 17U of the second electrical component support 17. Therefore, the low-voltage cable 37 drawn out from above the first electrical component support 16 can be routed to the upper part of the second electrical component support 17 and easily connected to the second connection portion 35c of the second circuit board 35.

[0045] (Connection structure of the second high-voltage cable) One end of the second high-voltage cable 38 is connected to the fourth connection part 15e, which is a connection terminal provided at the end of the high-voltage circuit 33A on the moving axis A side of the first circuit board 15, and the other end is connected to the terminal block 36 for each indoor unit of the second electrical component support part 17. Compared to the first high-voltage cable 14, the second high-voltage cable 38 has a smaller outer diameter due to its smaller current value and is more prone to bending. Although it is thicker than the low-voltage cable 37, it has the same degree of flexibility as the low-voltage cable 37.

[0046] In the connection structure of the second high-voltage cable 38, similar to the connection structure of the first high-voltage cable 14 described above, the fourth connection part 15e is located on the side of the movable axis A on the mounting surface 15a of the first substrate 15 in the X direction along the front part 7F. This allows the length of the second high-voltage cable 38 to be shortened, so that the portion of the second high-voltage cable 38 that moves together with the second electrical component support part 17 when the second electrical component support part 17 moves around the movable axis A is shortened. Therefore, when the second electrical component support part 17 is moved and fixed in the closed position P1, it is suppressed that the second high-voltage cable 38 will be routed in a way that was not originally intended. This suppresses the second high-voltage cable 38 from coming close to electrical components that emit electromagnetic noise or other cables that propagate electromagnetic noise (for example, the cable connected to the compressor 6). Therefore, it is suppressed that electromagnetic noise from other cables is superimposed on the second high-voltage cable 38. Furthermore, by suppressing the superposition of electromagnetic noise onto the second high-voltage cable 38, the propagation of electromagnetic noise from the second high-voltage cable 38 to other cables can be suppressed.

[0047] As shown in Figure 4, the step-down unit 31 of the first electrical component support unit 16 is mounted on a third circuit board 41 provided along the rear surface 7R on the internal space B side, i.e., the rear surface 7R side, of the first electrical component support unit 16. The third circuit board 41 is a sub-control board (for example, a power board) for controlling the outdoor unit 1 together with the first circuit board 15, and the third circuit board 41 may be formed integrally with the first circuit board 15. The third circuit board 41 is mounted with electrical components that constitute the step-down unit 31, which is a switching power supply circuit that steps down the high voltage supplied from the first circuit board 15, a conversion unit 32 that converts the high voltage supplied from the first circuit board 15 from AC to DC, and a drive circuit 33 that drives the compressor 6.

[0048] Furthermore, on the third substrate 41 side of the first electrical component support section 16, that is, on the internal space B side, a cooling device 39 is provided for cooling heat-generating components such as power semiconductors (not shown) on the third substrate 41. The cooling device 39 has a heat dissipation member 40 that is thermally connected to the heat-generating component, which is fixed along the Z direction of the first support frame 21 of the first electrical component support section 16. Cooling pipes 19 of the refrigerant circuit are connected to the heat dissipation member 40 using fixing brackets 20, and the heat-generating component is cooled by removing heat from the heat dissipation member 40 with the refrigerant flowing through the cooling pipes 19. For example, during maintenance of the outdoor unit 1, maintenance work is performed in the internal space B of the machine room 9 to attach and detach the cooling pipes 19, which are an example of components constituting the refrigerant circuit, to the heat dissipation member 40.

[0049] (Securing each cable) Figure 9 is a view from above of the first electrical component support section 16 and the second electrical component support section 17 in the embodiment. As shown in Figures 3, 4, and 9, the first electrical component support section 16 has a plurality of fixing sections 43 (43A to 43D) to which the first high-voltage cable 14, the low-voltage cable 37, and the second high-voltage cable 38 are each fixed. For example, cable ties are used as the fixing sections 43, and the cables are bundled together and fixed to the first support frame 21 that constitutes the first electrical component support section 16.

[0050] As an example, the fixing part 43A for the low-voltage cable is fixed to the upper end surface 21a of the first support frame 21 of the first electrical component support part 16. The low-voltage cable 37, which is pulled upward from the third connection part 15d of the low-voltage circuit 33B of the first circuit board 15, is arranged along the upper end surface 21a of the second electrical component support part 17, as shown in Figure 9, and is fixed by the two fixing parts 43A for low-voltage cables. This prevents the low-voltage cable 37 from protruding from the first electrical component support part 16 into the internal space B when the second electrical component support part 17 moves around the movable axis A.

[0051] Figure 10 is a view of the first electrical component support section 16 in the embodiment, as seen from the Y direction perpendicular to the front section 7F. As shown in Figure 10, in the internal space B enclosed by the first electrical component support section 16 and the second electrical component support section 17, piping 18 constituting the refrigerant circuit is provided, extending upward from the first electrical component support section 16.

[0052] When viewing the extended portion 18a of the piping 18, which is located above the upper end of the first electrical component support portion 16, from a direction perpendicular to the front portion 7F of the housing 7, the low-voltage cable 37 is provided such that the portion 37b extending from the fixing portion 43A for low-voltage cables (described later) to the low-voltage circuit 33B of the first circuit board 15 does not enter the internal space B from the first electrical component support portion 16.

[0053] The region R in which the extended portion 18a of the piping 18 is located corresponds to the projected region obtained by projecting the extended portion 18a onto the front portion 7F, i.e., the XZ plane. In other words, portion 37b of the low-voltage cable 37 is routed within region R in the internal space B so as not to protrude from the first electrical component support portion 16. Specifically, the position of the fixing portion 43A for the low-voltage cable is set so that portion 37b of the low-voltage cable 37 is brought close to the upper end surface 21a of the first substrate 15 and the first support frame 21 and does not hang down from the first electrical component support portion 16, and the length of the low-voltage cable 37 is set so that portion 37b of the low-voltage cable 37 is not too long relative to the distance between the fixing portion 43A for the low-voltage cable and the first substrate 15.

[0054] This prevents the portion 37b of the low-voltage cable 37 from coming into contact with the extended portion 18a of the piping 18 located in the region R on the internal space B side from the first electrical component support 16, thereby preventing the insulation material of the low-voltage cable 37 from being damaged by the heat of the piping 18, and also prevents water droplets condensed on the piping 18 from traveling along the low-voltage cable 37 to the first substrate 15 or the second substrate 35 and damaging the electronic circuits, etc.

[0055] Furthermore, a shared fixing portion 43B for fixing the low-voltage cable 37 and the second high-voltage cable 38 is provided on the second support frame 22 of the second electrical component support section 17. The low-voltage cable 37 is positioned along the upper end of the second support frame 22 of the second electrical component support section 17. The shared fixing portion 43B is positioned in the second electrical component support section 17 above the first circuit board 15 of the first electrical component support section 16, and on the side of the movable axis A side of the second connection portion 35c of the second circuit board 35.

[0056] The low-voltage cable 37 is fixed by the shared fixing part 43B arranged in this manner, which prevents the portions of the low-voltage cable 37 and the second high-voltage cable 38 near the moving axis A from moving towards the internal space B side from the first electrical component support part 16 when the second electrical component support part 17 moves around the moving axis A. As the second electrical component support part 17 moves from the open position P2 to the closed position P1, the shared fixing part 43B moves towards the front part 7F side in the Y direction, so the portion of the low-voltage cable 37 from the shared fixing part 43B to the fixing part 43A for the low-voltage cable becomes more prone to bending towards the front part 7F side. Therefore, the low-voltage cable 37 is prevented from bending and protruding into the internal space B, thus preventing the low-voltage cable 37 from coming into contact with the piping 18 located in the internal space B and damaging the insulation material of the low-voltage cable 37 due to the heat of the piping 18, and preventing water droplets condensed on the piping 18 from traveling along the low-voltage cable 37 to the first circuit board 15 or the second circuit board 35 and damaging the electronic circuits, etc. In addition, the outdoor unit 1 is equipped with a shared fixing part 43B, which reduces the number of fixing parts 43 used.

[0057] Furthermore, the fixing portion 43A for the low-voltage cable 37 and the shared fixing portion 43B, to which the low-voltage cable 37 is fixed, are not limited to the arrangement described above. It is sufficient that at least one of the first electrical component support portion 16 and the second electrical component support portion 17 is positioned such that portion 37b of the low-voltage cable 37 does not protrude from the first electrical component support portion 16 within the region R in the internal space B.

[0058] Furthermore, as shown in Figures 3 and 5, the machine room 9 is provided with a noise reduction unit 46 to remove electromagnetic noise from the current flowing through the second high-voltage cable 38. The second high-voltage cable 38 is drawn out from the fourth connection part 15e of the high-voltage circuit 33A of the first circuit board 15 and extends upward along the movable axis A at the end 16a on the movable axis A side of the first electrical component support part 16.

[0059] The removal section 46 is fixed to the end 16a on the movable axis A side of the first electrical component support section 16 by a fixing section 43C for the second high-voltage cable. The removal section 46 is provided in the second high-voltage cable 38 near the upper end of the end 16a of the first electrical component support section 16. Furthermore, the removal section 46 is positioned on the fourth connection section 15e side of the high-voltage circuit 33A than the position of the common fixing section 43B that fixes both the second high-voltage cable 38 and the low-voltage cable 37. In other words, the second high-voltage cable 38 is routed upward from the fourth connection section 15e, passes through the removal section 46, and is fixed at the common fixing section 43B. The removal section 46 is, for example, a noise filter member such as a ferrite core.

[0060] Here, when the second electrical component support 17 moves around the movable axis A, the portion of the second high-voltage cable 38 that moves with the second electrical component support 17 is mainly the portion from the shared fixed part 43B to the indoor unit terminal block 36. Also, the current flows from the fourth connection part 15e of the first circuit board 15 toward the indoor unit terminal block 36. Therefore, when the second electrical component support 17 moves around the movable axis A, the portion of the second high-voltage cable 38 that moves with the second electrical component support 17 is removed by the removal part 46. Consequently, even if the moved second high-voltage cable 38 approaches other cables, it is possible to prevent electromagnetic noise propagating through the second high-voltage cable 38 from superimposing on other cables.

[0061] As described above, the machine room 9 is provided with a noise reduction unit 46 to remove electromagnetic noise from the current flowing through the first high-voltage cable 14. The first high-voltage cable 14 is drawn out from the second electrical component support unit 17 and extends downward along the movable axis A at the end 16a on the movable axis A side of the first electrical component support unit 16.

[0062] The removal section 46 is fixed to the end 16a on the movable axis A side of the first electrical component support section 16 by a fixing section 43D for the first high-voltage cable. The removal section 46 is positioned above the upper end of the end 16a on the movable axis A side of the first high-voltage cable 14.

[0063] As a result, even if there is slack in the length of the first high-voltage cable 14, the first high-voltage cable 14 is fixed to the movable axis A side, so when the second electrical component support part 17 is moved around the movable axis A from the open position P2 to the closed position P1, the first high-voltage cable 14 is prevented from moving to the internal space B side, and electromagnetic noise propagated from the external AC power supply 11 to the first high-voltage cable 14 is prevented from propagating to the high-voltage circuit 33A of the first circuit board 15.

[0064] (Current flow in the first and second electrical component support sections) The current flow in the first electrical component support section 16 and the second electrical component support section 17, which are configured as described above, will now be explained. As shown in Figure 3, the current supplied from the external AC power supply 11 is supplied to the high-voltage circuit 33A of the first circuit board 15 of the first electrical component support section 16 via the power terminal block 12 and the first high-voltage cable 14 of the second electrical component support section 17. The current supplied to the high-voltage circuit 33A is sent to the outdoor unit power supply filter circuit F1 and the indoor unit power supply filter circuit F2.

[0065] As shown in Figure 4, the current that has passed through the outdoor unit power filter circuit F1 is supplied to the third circuit board 41 located on the back side (internal space B side) of the first circuit board 15, and is sent to the step-down unit 31 (switching power supply circuit) and the conversion unit 32. As shown in Figures 3 and 4, the current that has passed through the indoor unit power filter circuit F2 is sent via the second high-voltage cable 38 to the indoor unit terminal block 36 of the second electrical component support unit 17, and is supplied to the indoor unit 2 via the indoor unit terminal block 36.

[0066] In the step-down unit 31, for example, the voltage is stepped down to two voltages, and each voltage is supplied to the low-voltage circuit 33B of the first circuit board 15. As shown in Figure 3, the current flowing due to the two voltages supplied to the low-voltage circuit 33B is sent to the second circuit board 35 of the second electrical component support unit 17 via the low-voltage cable 37. As shown in Figure 4, in the conversion unit 32, the AC voltage is converted to DC voltage and the voltage is boosted, and the current flowing due to the boosted voltage is sent to the compressor 6 via the drive circuit 33.

[0067] (Effects of the example) As described above, in the embodiment, the outdoor unit 1 has the end 16a on the side portion 7S side of the first electrical component support portion 16 and the end 17a on the front portion 7F side of the second electrical component support portion 17 adjacent to each other in the machine room 9, and the second electrical component support portion 17 is provided so as to be movable around a movable axis A along the front portion 7F and the side portion 7S. The first circuit board 15 supported by the first electrical component support portion 16 has a first connection portion 15c to which the first high-voltage cable 14 is connected, and the position of the first connection portion 15c on the first circuit board 15 is located at the end 15b on the movable axis A side of the first circuit board 15. In this embodiment, since the end 17a of the second electrical component support portion 17 is movable around the movable axis A relative to the end 16a of the first electrical component support portion 16, the internal space B can be easily accessed, thus ensuring the workability of maintenance work such as attaching and detaching cooling pipes 19 and other parts in the internal space B of the machine room 9. In addition, in this embodiment, the position of the first connection portion 15c on the first substrate 15 is located at the end portion 15b on the movable axis A side of the first substrate 15, which makes it possible to shorten the first high-voltage cable 14 connected to the second electrical component support portion 17. As a result, the first high-voltage cable 14, which moves together with the second electrical component support portion 17, is prevented from coming close to other cables on which electromagnetic noise propagates, and the superposition of electromagnetic noise on the first high-voltage cable 14 is suppressed. Furthermore, by suppressing the superposition of electromagnetic noise on the first high-voltage cable 14, the propagation of electromagnetic noise from the first high-voltage cable 14 to other cables is suppressed.

[0068] Furthermore, in the outdoor unit 1 of the embodiment, the first circuit board 15 of the first electrical component support section 16 has a high-voltage circuit 33A on the side of the movable axis A in the X direction along the front section 7F, and a low-voltage circuit 33B on the opposite side of the movable axis A. The second electrical component support section 17 has a second circuit board 35 to which a low voltage is supplied from the low-voltage circuit 33B, and a low-voltage cable 37 connecting the low-voltage circuit 33B of the first circuit board 15 and the second circuit board 35 is provided in the machine room 9. As a result, by positioning the low-voltage circuit 33B, to which the flexible low-voltage cable 37 is connected, at a position far from the movable axis A on the first circuit board 15, that is, on the opposite side of the movable axis A, the movement of the second electrical component support section 17 is not hindered by the low-voltage cable 37, making it possible to move the second electrical component support section 17 smoothly and improving the workability of maintenance performed in the internal space B. In addition, by positioning the low-voltage circuit 33B far from the movable axis A on the first substrate 15, space can be secured on the movable axis A side, making it possible to position the high-voltage circuit 33A, to which the first high-voltage cable 14, which is difficult to route, is connected, on the movable axis A side.

[0069] Furthermore, in the outdoor unit 1 of the embodiment, when viewing the extended portion 18a of the piping 18 located above the upper end of the first electrical component support portion 16 (upper end surface 21a of the first support frame 21) from the Y direction perpendicular to the front portion 7F, the portion 37b of the low-voltage cable 37 extending from the fixing portion 43A for the low-voltage cable to the first substrate 15 is provided so as not to enter the internal space B side from the first electrical component support portion 16. This prevents the portion 37b of the low-voltage cable 37 from coming into contact with the extended portion 18a of the piping 18 located in the region R on the internal space B side from the first electrical component support portion 16, thereby preventing the insulation material of the low-voltage cable 37 from being damaged by the heat of the piping 18, and also prevents water droplets condensed on the piping 18 from traveling along the low-voltage cable 37 to the first substrate 15 or second substrate 35 and damaging electronic circuits, etc.

[0070] Furthermore, in the outdoor unit 1 of the embodiment, the second circuit board 35 of the second electrical component support section 17 has a second connection section 35c to which the low-voltage cable 37 is connected, and the low-voltage cable 37 is arranged along the upper end of the second electrical component support section 17. The common fixing section 43B is located in the second electrical component support section 17 above the first circuit board 15 of the first electrical component support section 16, and on the side of the movement axis A closer to the second connection section 35c of the second circuit board 35. This prevents the portions of the low-voltage cable 37 and the second high-voltage cable 38 near the movement axis A, which are more flexible than the first high-voltage cable 14, from moving from the first electrical component support section 16 towards the internal space B when the second electrical component support section 17 moves around the movement axis A. As the second electrical component support section 17 moves from the open position P2 to the closed position P1, the common fixing section 43B moves towards the front section 7F in the Y direction. As a result, the portion of the low-voltage cable 37 from the common fixing section 43B to the fixing section 43A for the low-voltage cable becomes more prone to bending towards the front section 7F. This prevents the low-voltage cable 37 from bending in a way that protrudes into the internal space B, thus preventing the low-voltage cable 37 from coming into contact with the piping 18 located in the internal space B and damaging the insulation material of the low-voltage cable 37 due to the heat of the piping 18, and preventing water droplets condensed on the piping 18 from traveling along the low-voltage cable 37 to the first circuit board 15 or the second circuit board 35 and damaging the electronic circuits, etc.

[0071] Furthermore, in the embodiment, the second electrical component support section 17 of the outdoor unit 1 has the power terminal block 12 located at the end 17b opposite to the movable axis C side of the second electrical component support section 17. This ensures a large distance between the power terminal block 12 and the first circuit board 15 of the first electrical component support section 16. Therefore, even when using a first high-voltage cable 14 that is not easily bent, the long distance to the first circuit board 15 allows for a gentler curve when routing the first high-voltage cable 14 to avoid obstacles, making it easier to route and connect the first high-voltage cable 14. In addition, the force applied to the first high-voltage cable 14 when the second electrical component support section 17 is moved is reduced, thus preventing damage to the first high-voltage cable 14.

[0072] Furthermore, in the outdoor unit 1 of the embodiment, the machine room 9 is provided with a second high-voltage cable 38 that sends high voltage from the first circuit board 15 to the second electrical component support section 17, and a noise reduction section 46 provided on the second high-voltage cable 38 that removes electromagnetic noise from the current flowing through the second high-voltage cable 38. The noise reduction section 46 is fixed to the end 16a on the movable axis A side of the first electrical component support section 16, and the second high-voltage cable 38 is positioned along the movable axis A at the end 16a on the movable axis A side of the first electrical component support section 16. The current flowing through the second high-voltage cable 38 flows from the first circuit board 15 towards the second electrical component support section 17. Therefore, when the second electrical component support section 17 moves around the movable axis A, electromagnetic noise is removed by the noise reduction section 46 in the portion of the second high-voltage cable 38 that moves together with the second electrical component support section 17. Therefore, even if the moving second high-voltage cable 38 approaches other cables, it is possible to prevent electromagnetic noise propagating through the second high-voltage cable 38 from being superimposed on other cables.

[0073] Furthermore, in the outdoor unit 1 of the embodiment, the first electrical component support section 16 has a first notch groove 26 that allows the second electrical component support section 17 to rotate around the movable axis A and detachably supports the second electrical component support section 17, and a second notch groove 28 that supports the second electrical component support section 17 after it has been removed from the first notch groove 26 and fixes it in the open position P2. This makes it possible to easily fix the second electrical component support section 17 in the open position P2, and prevents the second electrical component support section 17 from accidentally moving from the open position P2 to the closed position P1, so that maintenance work in the internal space B can be performed stably.

[0074] The following briefly describes some modifications. This disclosure includes the fact that at least one of the first electrical component support portion 16 and the second electrical component support portion 17 is provided to be movable around a movable axis A along the front portion 7F and the side portion 7S.

[0075] (modified version) Although not shown, the end portion 16a of the first electrical component support portion 16 may be provided so as to be movable around the movable axis A relative to the end portion 17a of the second electrical component support portion 17. In this case, a front panel (not shown) is detachably provided on the machine room 9 side of the front portion 7F of the housing 7. By removing the front panel from the front portion 7F side and moving the first electrical component support portion 16 around the movable axis A relative to the second electrical component support portion 17, maintenance work can be easily performed in the internal space B covered by the first electrical component support portion 16. This case applies, for example, to a structure in which a cooling device 39 is attached to the second electrical component support portion 17, or to a structure without a cooling device 39. In a structure without a cooling device 39, by moving the first electrical component support portion 16, maintenance work such as replacing the coil of a four-way valve, which is an example of a component constituting a refrigerant circuit, can be easily performed.

[0076] Furthermore, although not shown in the figures, both the first electrical component support section 16 and the second electrical component support section 17 may be provided so as to be movable relative to the component on which the movable axis A is provided. This allows, for example, the front panel or the side panel 7b to be selectively removed from either the front section 7F or the side section 7S of the housing 7, and the first electrical component support section 16 or the second electrical component support section 17 to be moved around the movable axis A, thereby facilitating maintenance work in the internal space B enclosed by the first electrical component support section 16 and the second electrical component support section 17.
