Description

TITLE OF THE INVENTION: ELECTRICAL COMPONENT MODULE AND OUTDOOR UNIT Field

[0001] The present invention relates to an electrical component module and an outdoor unit. Background

[0002] There is a known technology for transmitting and receiving a signal of, for example, a demand signal for electric power demand monitoring, a control signal of home energy management system (HEMS), or the like between an outdoor unit and an outside of the outdoor unit in order to control electric power consumed in an air conditioner. In some cases, the function for transmitting and receiving this type of signal is added to the outdoor unit as an extension function. In this case, an expansion board, which has a communication circuitry for transmitting and receiving a signal, is provided in an electrical component module, which is included in the outdoor unit. This expansion board is provided as an independent board separately from the main board that has a control circuitry, which controls the outdoor unit. As a result of this, it is possible to communalize the main board in each of the electrical component modules included in the respective outdoor units, regardless of whether or not the extension function is added to the outdoor unit.

[0003] Patent Literature 1: International Publication Pamphlet No. WO 2017 / 037820 Summary Technical Problem

[0004] It is preferable that the above described expansion board is constituted such that a power supply, which supplies electric power to the communication circuitry, is isolated from a primary side circuitry included in a power supply circuitry, provided on a main board, and is also provided as an independent system separately from another circuitry, provided on the main board. In other words, as a result of the power supply, provided on the expansion board, being isolated from the power supply circuitry, provided on the main board, it is possible to ensure safety in a case where a user touches a communication cable or the like that is connected to the expansion board and that is used to communicate with the outside of the outdoor unit. In addition, by constituting the communication circuitry, provided on the expansion board, as the independent system that is separated from the control circuitry, provided on the main board, it is possible to prevent the expansion board from becoming an insulation failure in a case where an insulation failure occurs on the main board, and it is thus possible to ensure user safety.

[0005] Accordingly, it is conceivable to additionally provide a power supply circuitry on the expansion board separately from the power supply circuitry, provided on the main board. However, for example, electromagnetic noise, which is generated in the primary side circuitry included in the power supply circuitry, such as a switching power supply, becomes a noise source, so that there is a problem in that electromagnetic noise that is superimposed on an Alternating Current (AC) cable, which functions as a power supply cable that supplies electric power from an external power supply to each of the main board and the expansion board, and a communication cable that is connected to the expansion board, tends to increase caused due to the noise sources of both of the power supply circuitry, which is provided on the main board, and the power supply circuitry, which is provided on the expansion board.

[0006] Accordingly, the disclosed technology has been conceived in light of the circumstances described above, and an object thereof is to provide an electrical component module and an outdoor unit capable of suppressing an influence of electromagnetic noise, which is generated by a power supply circuitry, on a communication cable and a power supply cable.

[0010] Hereinafter, preferred embodiments of an electrical component module and an outdoor unit disclosed in the present application, will be described in detail below with reference to the accompanying drawings. Furthermore, the electrical component module and the outdoor unit disclosed in the present application, is not limited by the embodiments described below.

[0011] [Embodiment] (Outdoor unit) FIG. 1 is a schematic diagram illustrating an outdoor unit that includes an electrical component module according to an embodiment. In FIG. 1, the left-right direction of an outdoor unit 1 is denoted by an X-axis direction, the up-down direction of the outdoor unit 1 is denoted by a Y- axis direction, and the depth direction of the outdoor unit 1 is denoted by a Z-axis direction. In each of the drawings illustrated in FIG. 1 and subsequent drawings, the X-axis, the Y-axis, and the Z-axis are also indicated in the same manner as in FIG. 1.

[0012] The outdoor unit 1 according to the embodiment is included by the air conditioner, and includes, as illustrated in FIG. 1, a compressor (not illustrated) that compresses a refrigerant, a heat exchanger (not illustrated) that performs heat exchange between the refrigerant, flowing in due to a drive of a compressor, and outside air, a propeller fan 5 for sending outside air to the heat exchanger, a fan motor (not illustrated) that rotates the propeller fan 5, an electrical component module 6 that controls the compressor, the fan motor, and the like, and a casing 7 that accommodates the compressor, the heat exchanger, the propeller fan 5, the fan motor, and the electrical component module 6 described above in an interior portion of the casing 7. The electrical component module 6 is arranged at one end portion of the interior portion of the casing 7.  The arrangement of the electrical component module 6 in the interior portion of the casing 7, will be described in detail later.

[0013] (Electrical component module) FIG. 2 is a block diagram illustrating the electrical component module 6 according to the embodiment. FIG. 3 is a front view illustrating the electrical component module 6 according to the embodiment, and illustrates a state in which the electrical component module 6 is arranged in the interior portion of the casing 7. As illustrated in FIG. 2 and FIG. 3, the electrical component module 6 includes a control board 11 serving as a first board, and a communication board 12 serving as a second board.

[0014] The control board 11 has a control circuitry 13 that controls the outdoor unit 1, and a first power supply circuitry 13, and is what is called a main board that controls the compressor, the fan motor, and the like that are included in the outdoor unit 1.

[0015] The communication board 12 has a communication circuitry 16 that communicates with an outside of the outdoor unit 1, and a second power supply circuitry 17 that supplies electric power to the communication circuitry 16. The communication board 12 is a board that is used to transmit and receive, for example, a signal, such as a demand signal, for electric power demand monitoring performed in the air conditioner, between the outdoor unit 1 and an external network 18, which is provided the outside of the outdoor unit 1, and is an expansion board for expanding the function of the control board 11, which is provided in the outdoor unit 1.

[0016] As illustrated in FIG. 3, the first power supply circuitry 14, which is provided on the control board 11, has a primary side circuitry 14A and a secondary side circuitry 14B, and the primary side circuitry 14A and the secondary side circuitry 14B are separately arranged on either side of a boundary line B1 indicated on a mounting surface 11a with respect to the X-axis direction (hereinafter, also referred to as a first direction X) serving as a first direction that is along the mounting surface 11a of the control board 11.  In other words, on the control board 11, the primary side circuitry 14A, which is included in the first power supply circuitry 14, is located on one end portion side of the control board 11 in the first direction X, and the secondary side circuitry 14B, which is included in the first power supply circuitry 14, is located on the other end portion side of the control board 11 in the first direction X.

[0017] Here, the mounting surface 11a of the control board 11 (hereinafter, also referred to as the mounting surface 11a on the front side) indicates a mounting surface that is disposed on a side opposite to the side, which faces a fixed plate 21 that will be described later, that is, the mounting surface that faces an outer side of the outdoor unit 1. Furthermore, on the control board 11, an electronic component (not illustrated) is also mounted on a mounting surface 11b (hereinafter, also referred to as the mounting surface 11b located on the back side.) that faces the fixed plate 21.  Furthermore, a filter board (not illustrated) that has a filter circuitry (not illustrated) to which electric power is input from an external power supply 19, is provided on the side opposite to the control board 11 side of the fixed plate 21, and the electric power, which is supplied from the external power supply 19, is sent to the primary side circuitry 14A, which is included in the first power supply circuitry 14, via the filter circuitry. On the control board 11 according to the embodiment, double-sided mounting, in which the electronic components are mounted on both surfaces of the front surface and the back surface of the control board 11, are implemented, but single-sided mounting, in which the electronic components are mounted only on the front side of the mounting surface 11a, may be implemented. Furthermore, in FIG. 3 and the like, the Y-axis direction, which is perpendicular to the first direction X along the mounting surface 11a of the control board 11 and which is also along the mounting surface 11a, is denoted by the second direction (hereinafter, also referred to as a second direction Y.), and the Z-axis direction, which is perpendicular to an X-Y plane and which is a thickness direction of the control board 11, is denoted by a third direction (hereinafter, also referred to as a third direction Z.).

[0018] In the present embodiment, the first direction X is a left-right direction (a horizontal direction) of the electrical component module 6, but the first direction may also be changed from the X-axis direction (the left-right direction of the outdoor unit 1) to the Y-axis direction (the up-down direction of the outdoor unit 1) in accordance with the orientation of the electrical component module 6 that is arranged in the interior portion of the casing 7, which is included in the outdoor unit 1.  An example of the first power supply circuitry 14 includes a circuitry having a configuration in which the primary side circuitry 14A is an alternating current circuitry, the secondary side circuitry 14B is a direct current circuitry, and a switching power supply (not illustrated) is arranged between the primary side circuitry 14A and the secondary side circuitry 14B. However, the configuration is not limited to this example, the first power supply circuitry 14 may have a configuration in which both of the primary side circuitry 14A and the secondary side circuitry 14B may be direct current circuitries, or both of the primary side circuitry 14A and the secondary side circuitry 14B may be alternating current circuitries. Furthermore, the first power supply circuitry 14 may have any configuration as long as a power supply circuitry is able to isolate the primary side circuitry 14A and the secondary side circuitry 14B, and is able to transform a voltage, which is supplied from the primary side circuitry 14A, such as a configuration in which, for example, a power supply circuitry that includes a transformer and a regulator instead of the switching power supply.

[0019] Similar to the first power supply circuitry 14 included in the control board 11, the second power supply circuitry 17, which is provided on the communication board 12, has a primary side circuitry 17A and a secondary side circuitry 17B, and the primary side circuitry 17A and the secondary side circuitry 17B are separately arranged on either side of a boundary line B2 indicated on a mounting surface 12a with respect to the first direction X along the mounting surface 12a of the communication board 12. In other words, the primary side circuitry 17A, which is included in the second power supply circuitry 17, is located on one end portion side of the communication board 12 in the first direction X.  The secondary side circuitry 17B, which is included in the second power supply circuitry 17, is located on the other end portion side of the communication board 12 in the first direction X. Furthermore, on the mounting surface 12a of the communication board 12, a filter circuitry (not illustrated), to which electric power is input from the external power supply 19, is provided. Here, the mounting surface 12a of the communication board 12 indicates a mounting surface, which is disposed on a side opposite to the fixed plate 21 side that will be described later, that is, the mounting surface that faces the inner surface of the casing 7, which is included in the outdoor unit 1. On the communication board 12 according to the embodiment, single-sided mounting has been implemented, but doublesided mounting may be implemented.

[0020] The first direction X is a direction along the mounting surface 12a of the communication board 12, and is also a direction along the mounting surface 11a of the control board 11. An example of the second power supply circuitry 17 includes, similarly to the first power supply circuitry 14, which is included in the control board 11, a circuitry having a configuration in which the primary side circuitry 17A is an alternating current circuitry, the secondary side circuitry 17B is a direct current circuitry, and a switching power supply (not illustrated) is arranged between the primary side circuitry 17A and the secondary side circuitry 17B. However, the configuration is not limited to this example, the second power supply circuitry 17 may be configured such that both of the primary side circuitry 17A and the secondary side circuitry 17B may be direct current circuitries, or both of these may be alternating current circuitries.

[0021] The control board 11 and the communication board 12 are perpendicular to the first direction X, and are arranged side by side in the second direction Y that is along the mounting surface 11a (11b) of the control board 11. Furthermore, the electrical component module 6 according to the embodiment is arranged in the second direction Y at one end in the first direction X of the interior portion of the casing 7, which is included in the outdoor unit 1 (see FIG. 1).

[0022] Furthermore, the electrical component module 6 includes, as illustrated in FIG. 3, the fixed plate 21 serving as a fixed member to which the control board 11 is fixed, and a partition plate 22 serving as a partition member that partitions the interior space of the electrical component module 6 and that is arranged on the fixed plate 21 alongside the control board 11 in the second direction Y.

[0023] The fixed plate 21 is formed in a concave shape having an interior space in which the control board 11 and the communication board 12 are arranged, and is fixed to the casing 7, which is included in the outdoor unit 1.  On the fixed plate 21, the control board 11 is arranged on one end side (an upper end side according to the embodiment) in the second direction Y, and the partition plate 22 and the communication board 12 are arranged on the other end side (a lower end side according to the embodiment) in the second direction Y.

[0024] FIG. 4 is a perspective view illustrating a part of the fixed plate 21 and the partition plate 22 included in the electrical component module 6 according to the embodiment.  FIG. 5 is a schematic side view illustrating a part of the fixed plate 21 and the partition plate 22 included in the electrical component module 6 according to the embodiment. FIG. 6 is a perspective view illustrating a relevant part of the fixed plate 21 included in the electrical component module 6 according to the embodiment.

[0025] As illustrated in FIG. 3, FIG. 4, and FIG. 5, the partition plate 22 partitions the interior space of the electrical component module 6 into an upper section portion 23U and a lower section portion 23L, so as to form a two- section structure constituted by the lower section portion 23L that is located between the partition plate 22 and the fixed plate 21, and the upper section portion 23U that is located on the side opposite to the lower section portion 23L with respect to the partition plate 22. Both ends of the partition plate 22 in the first direction X are fixed to the fixed plate 21 by being screwed or the like.  The partition plate 22 is made of a material having a conductive property, and is configured to be able to block electromagnetic waves.

[0026] The partition plate 22 has a supporting surface 22a that supports the communication board 12, and the communication board 12 is fixed to the fixed plate 21 via the partition plate 22. The supporting surface 22a of the partition plate 22 is formed such that the control board 11 side of the supporting surface 22a is inclined in a direction in which the lower section portion 23L decreases in the second direction Y. The communication board 12 is arranged on the supporting surface 22a such that the mounting surface 12a is placed along the supporting surface 22a of the partition plate 22. As a result of this, the mounting surface 12a of the communication board 12 is provided so as to be inclined relative to the X-Y plane. Furthermore, the second power supply circuitry 17, which is provided on the communication board 12, is connected to the partition plate 22 by a grounding wire (not illustrated).

[0027] Furthermore, the communication board 12 is arranged at a position closer to the control board 11 side on the supporting surface 22a. As a result of this, it is possible to arrange an electronic component group 24 that has been mounted on the mounting surface 12a of the communication board 12 at a position closer to the control board 11 side on the supporting surface 22a, and it is thus possible to reduce a protrusion amount of the electronic component group 24 protruding in the third direction Z that is perpendicular to the X-Y plane. For this reason, it is possible to secure a large gap between the electronic component group 24, mounted on the communication board 12, and the inner surface of the casing 7, so that, for example, it is possible to prevent damage to the communication board 12 by avoiding a collision between the electronic component group 24, mounted on the mounting surface 12a of the communication board 12, and the casing 7.

[0028] As illustrated in FIG. 4 and FIG. 5, on the mounting surface 12a that is provided on the communication board 12 and that is located on the side opposite to the supporting surface 22a of the partition plate 22, a maximum protrusion amount H1 of the electronic component group 24 that is arranged on one end portion, disposed on the control board 11 side, and that protrudes from the mounting surface 12a, is larger than a maximum protrusion amount H2 of the electronic component group 24 that is arranged on the other end portion, located on the side opposite to the control board 11 side, and that protrudes from the mounting surface 12a.

[0029] As a result of this, on the mounting surface 12a of the communication board 12, it is possible to further suppress a protrusion amount of the electronic component group 24, protruding in the third direction Z that is perpendicular to the X-Y plane. For this reason, it is possible to further secure a gap between the electronic component group 24, mounted on the communication board 12, and the inner surface of the casing 7, so that, for example, it is possible to enhance the effect of preventing damage to the communication board 12 by avoiding a collision between the electronic component group 24, mounted on the mounting surface 12a of the communication board 12, and the casing 7.

[0030] Here, it is assumed that the boundary between one end portion, which is located on the control board 11 side on the mounting surface 12a of the communication board 12, and the other end portion, which is located on the side opposite to the one end portion, is defined to be a center line C in the second direction Y (an up-down direction) (see FIG. 5). In other words, in the embodiment, it is assumed that the above described boundary, between one end portion and the other end portion, is the center line C in a short side direction of the mounting surface 12a of the communication board 12.

[0031] Furthermore, an end portion, which is located on the control board 11 side on the supporting surface 22a of the partition plate 22 that supports the communication board 12, extends toward the lower section portion 23L side across the entire length of the first direction X. That is, the partition plate 22 has an extension piece 22b extending in the third direction Z that is perpendicular to the X-Y plane. As a result of this, the electromagnetic noise particularly generated by the first power supply circuitry 14, which is provided on the control board 11, is suppressed from entering the interior of the lower section portion 23L from the lower section portion 23L on the control board 11 side, by the extension piece 22b, so that it is possible to suppress the electromagnetic noise, which is emitted from the control board 11, from being superimposed on a first power supply cable 26, a second power supply cable 27 and a communication cable 28, which will be described later and which are arranged in the lower section portion 23L.

[0032] As illustrated in FIG. 2 and FIG. 3, the electrical component module 6 includes the first power supply cable 26 that supplies electric power from the external power supply 19 to the first power supply circuitry 14, which is included in the control board 11, the second power supply cable 27 that supplies electric power from the external power supply 19 to the second power supply circuitry 17, which is included in the communication board 12, and the communication cable 28 that is connected to the communication circuitry 16, which is provided on the communication board 12. The first power supply cable 26 and the second power supply cable 27 are, for example, AC cables, but are not limited to this example.  The wiring of each of the first power supply cable 26, the second power supply cable 27, and the communication cable 28, will be described later.

[0033] Furthermore, as illustrated in FIG. 3, FIG. 4, and FIG. 6, the electrical component module 6 includes a power supply terminal block 31 that has a terminal, which relays the first power supply cable 26 and the second power supply cable 27, a relay terminal block 32 that relays the second power supply cable 27, which is connected to the communication board 12 and which is extended from the power supply terminal block 31, and a communication terminal block 33 that has a terminal, which relays the communication cable 28. In the electrical component module 6, the communication terminal block 33, the communication board 12, the partition plate 22, the second power supply cable 27 (a connecting cable 27C described later), and the communication cable 28 (connecting cables 28B and 28C described later) are treated as expansion parts (optional parts) each of which is arbitrarily added.

[0034] The power supply terminal block 31, the relay terminal block 32, and the communication terminal block 33 are provided on a terminal block supporting surface 21a of the fixed plate 21, and is arranged at the lower section portion 23L that is located between the partition plate 22 and the fixed plate 21. Furthermore, the connection terminal, which is provided in each of the power supply terminal block 31, the relay terminal block 32, and the communication terminal block 33, is arranged at a position, which is not covered by the partition plate 22, so that workability at the time of connections of the cables, is ensured.

[0035] In the embodiment, in the first direction X of the lower section portion 23L, the power supply terminal block 31, the relay terminal block 32, and the communication terminal block 33, are arranged in this order from the side of the primary side circuitry 17A, which is provided on the communication board 12.  Therefore, the relay terminal block 32 is arranged side by side with the power supply terminal block 31 in the first direction X of the lower section portion 23L. In the embodiment, the relay terminal block 32 and the power supply terminal block 31 are arranged next to each other in the first direction X.  As a result of the electrical component module 6 having the relay terminal block 32, when the communication board 12 is added to the electrical component module 6, there is no need to fasten the first power supply cable 26 and the second power supply cable 27 together by removing the first power supply cable 26 (a connecting cable 26B described later) from the power supply terminal block 31 once. Therefore, it is possible to complete work to connect the second power supply cable 27 by simply connecting the second power supply cable 27 (the connecting cable 27C described later) to the relay terminal block 32, and it is thus possible to enhance workability when the communication board 12 is retrofitted.

[0036] As illustrated in FIG. 3 and FIG. 6, the power supply terminal block 31 and the primary side circuitry 17A, which is provided on the communication board 12, are arranged on the same side in the first direction X (on the right side in FIG. 3). The communication terminal block 33 and the secondary side circuitry 17B, which is provided on the communication board 12, are arranged on the same side in the first direction X (on the left side in FIG. 3).

[0037] As a result of this, it is possible to avoid each of the second power supply cable 27 and the communication cable 28, which are connected to the communication board 12, from being wired in an intersecting manner each other at a position in the lower section portion 23L, which is provided on the partition plate 22, so that it is possible to wire the second power supply cable 27 and the communication cable 28 such that the wiring routes of the respective second power supply cable 27 and the communication cable 28, are separated from each other. Consequently, for example, it is possible to suppress the electromagnetic noise, which is sent from the second power supply cable 27, from being superimposed on the communication cable 28 by avoiding the communication cable 28 from being intersected with the second power supply cable 27 in which the electromagnetic noise, received from the outside of the outdoor unit 1, is likely to be superimposed. As a result of this, it is possible to prevent malfunction of the electrical component module 6 caused by the electromagnetic noise.

[0038] Furthermore, both of the secondary side circuitry 14B, which is provided on the control board 11, and the secondary side circuitry 17B, which is provided on the communication board 12, are connected by a connecting cable 28C, which is included in the communication cable 28. The power supply terminal block 31 and the primary side circuitry 14A, which is provided on the control board 11, are arranged on the same side in the first direction X (on the right side in FIG. 3). The communication terminal block 33 and the secondary side circuitry 14B, which is provided on the control board 11, are arranged on the same side in the first direction X (on the left side in FIG. 3).

[0039] As a result of this, it is possible to avoid each of the first power supply cable 26 and the communication cable 28, which are connected to the control board 11, from being wired in an intersecting manner each other at a position in the lower section portion 23L, which is provided on the partition plate 22 or a position between the communication board 12 and the control board 11, so that it is possible to wire the first power supply cable 26 and the communication cable 28 such that the wiring routes of the respective first power supply cable 26 and the communication cable 28, are separated from each other.  For this reason, it is possible to suppress the electromagnetic noise, which is sent from the first power supply cable 26, from being superimposed on the communication cable 28.  As a result of this, it is possible to prevent malfunction of the electrical component module 6 caused by the electromagnetic noise.

[0040] As illustrated in FIG. 3, FIG. 4 and FIG. 6, the fixed plate 21 has the terminal block supporting surface 21a, on which the power supply terminal block 31, the relay terminal block 32, and the communication terminal block 33 are arranged. The terminal block supporting surface 21a of the fixed plate 21 is formed such that the control board 11 side of the terminal block supporting surface 21a is inclined in a direction in which the lower section portion 23L increases with respect to the second direction Y.  In other words, the terminal block supporting surface 21a of the fixed plate 21 is inclined along the supporting surface 22a of the partition plate 22 that is inclined as described above. As a result of this, it is possible to secure the space that is located between the terminal block supporting surface 21a and the partition plate 22 and that forms the lower section portion 23L, so that it is possible to avoid the lower section portion 23L, which is provided by the partition plate 22, from becoming narrow in accordance with the inclination of the supporting surface 22a of the partition plate 22, and it is thus possible to easily wire the first power supply cable 26, the second power supply cable 27, and the communication cable 28 that are to be arranged in the lower section portion 23L.

[0041] (Wiring of each cable) FIG. 7 is a schematic diagram for explaining an arrangement of each of the cables 26, 27, and 28 provided in the electrical component module 6 according to the embodiment. As illustrated in FIG. 7, the first power supply cable 26 and the second power supply cable 27 according to the embodiment, are constituted to have a common cable portion, which is extended from the external power supply 19 up to the power supply terminal block 31, and include a common cable 26A (27A), respectively, that is the same cable portion.

[0042] The first power supply cable 26 includes the common cable 26A (27A) that is extended from the external power supply 19 and is connected to the power supply terminal block 31, the connecting cable 26B that is extended from the power supply terminal block 31 and is connected to the filter circuitry provided on the filter board (not illustrated), and a connecting cable 26C that is extended from the filter circuitry provided on the filter board and is connected to the mounting surface 11a provided on the front side.

[0043] The second power supply cable 27 includes the common cable 27A (26A) that is extended from the external power supply 19 and is connected to the power supply terminal block 31, a connecting cable 27B that is extended from the power supply terminal block 31 and is connected to the relay terminal block 32, and the connecting cable 27C that is extended from the relay terminal block 32 and is connected to the mounting surface 12a of the communication board 12.

[0044] The communication cable 28 includes a connecting cable 28A that is extended from the external network 18 and is connected to the communication terminal block 33, a connecting cable 28B that is extended from the communication terminal block 33 and is connected to the mounting surface 12a of the communication board 12, and the connecting cable 28C that is extended from the mounting surface 12a of the communication board 12 and is connected to the mounting surface 11a of the front side of the control board 11.  The communication cable 28 connects the communication board 12 and the control board 11 by the connecting cable 28B, so that the signal, received from the external network 18, is transmitted to the control circuitry 13, which is provided on the control board 11, via the connecting cable 28C. The communication cable 28 is a bundle of a plurality of cables.  In other words, the connecting cable 28A, the connecting cable 28B, and the connecting cable 28C, are also a bundle of a plurality of cables. As one example, in the embodiment, the communication cable 28 includes four cables, and three cables are used as signal lines, whereas a single cable is used as a grounding wire. By using a combination in which one of the three signal line is electrically connected to the grounding wire, a demand signal is transmitted from the external network 18 to the communication circuitry 16, which is provided on the communication board 12.

[0045] In the first power supply cable 26, both of the common cable 26A that is extended from the external power supply 19, and the connecting cable 26B that connects the power supply terminal block 31 and the filter board, are connected to the power supply terminal block 31 that is arranged at the lower section portion 23L, which is located between the partition plate 22 and the fixed plate 21. Therefore, the first power supply cable 26 is connected to the first power supply circuitry 14, which is provided on the control board 11, by passing through the lower section portion 23L.

[0046] In the second power supply cable 27, the common cable 27A that is extended from the external power supply 19, the connecting cable 27B that connects the power supply terminal block 31 and the relay terminal block 32, and the connecting cable 27C that connects the relay terminal block 32 and the communication board 12, are connected to the power supply terminal block 31 that is arranged at the lower section portion 23L, which is located between the partition plate 22 and the fixed plate 21. The connecting cable 27C is pulled out from the lower section portion 23L to the upper section portion 23U, and is connected to the mounting surface 12a of the communication board 12. Therefore, the second power supply cable 27 is connected to the second power supply circuitry 17, which is provided on the communication board 12, by passing through the lower section portion 23L.

[0047] In the communication cable 28, the connecting cable 28B, which is extended from the communication terminal block 33, is pulled out from the lower section portion 23L to the upper section portion 23U, and is connected to the mounting surface 12a of the communication board 12.  Therefore, the communication cable 28 is connected to the communication circuitry 16, which is provided on the communication board 12, by passing through the lower section portion 23L.

[0048] In this way, in the electrical component module 6, the first power supply cable 26, the second power supply cable 27, and the communication cable 28, are arranged in the lower section portion 23L, which is located between the partition plate 22 and the fixed plate 21, and, as described above, the communication board 12 is arranged at the upper section portion 23U, which is located on a side opposite to the lower section portion 23L with respect to the partition plate 22. As a result of this, the partition plate 22 has a conductive property, so that the electromagnetic noise is blocked by the partition plate 22, and therefore, it is possible to suppress, by the partition plate 22, the electromagnetic noise, generated by both of the first power supply circuitry 14, which is provided on the control board 11, and the second power supply circuitry 17, which is provided on the communication board 12 and which is arranged at the upper section portion 23U, from being superimposed on the first power supply cable 26, the second power supply cable 27, and the communication cable 28 that are arranged at the lower section portion 23L. Furthermore, superimposition of the electromagnetic noise onto the first power supply cable 26 and the second power supply cable 27, is suppressed in this way, so that it is possible to suppress an adverse effect on the electronic device, which is provided an outside of the outdoor unit 1, as a result of the electromagnetic noise flowing outside of the outdoor unit 1 in a case where the electromagnetic noise is superimposed on the first power supply cable 26 (26A and 26B) and the second power supply cable 27 (27A to 27C) that transmit electric power, from which the electromagnetic noise has been removed by the filter circuitry (not illustrated) (a filter board or a filter circuitry of the communication board 12).

[0049] Furthermore, the structure is not limited to the structure according the embodiment, and the first power supply cable 26, the second power supply cable 27, and the communication cable 28 may be arranged at the upper section portion 23U, and the communication board 12 may be arranged at the lower section portion 23L. However, the structure according to embodiment is desirable in terms of enhancing a function of blocking the electromagnetic noise that is emitted from the first power supply circuitry 14, which is provided on the control board 11, and the second power supply circuitry 17, which is provided on the communication board 12, and that is superimposed on electromagnetic noise the first power supply cable 26, the second power supply cable 27, and the communication cable 28, by covering the first power supply cable 26, the second power supply cable 27, and the communication cable 28 by using the partition plate 22, and is desirable in that it makes installation work easier in a case where the communication board 12 is added to the electrical component module 6 retroactively.

[0050] Furthermore, the connecting cable 27C, which is included in the second power supply cable 27, is extended from the relay terminal block 32 to the power supply terminal block 31 side in the first direction X, and is connected to the mounting surface 12a of the communication board 12 at the same position as the position of the power supply terminal block 31 in the first direction X, when viewed from the mounting surface 12a of the communication board 12. In other words, for example, when the mounting surface 12a of the communication board 12 is viewed from the third direction Z, the connection position of the second power supply cable 27 on the mounting surface 12a of the communication board 12, is aligned with the position of the power supply terminal block 31 in the up-down direction that is the second direction Y.

[0051] As a result of this, the connecting cable 27C, which is included in the second power supply cable 27 and which extends from the relay terminal block 32 to the mounting surface 12a of the communication board 12, has a portion adjacent to the connecting cable 27B, which is extends from the power supply terminal block 31 to the relay terminal block 32 in the lower section portion 23L that is located between the partition plate 22 and the fixed plate 21. As a result of this, the connecting cable 27B and the connecting cable 27C, which are included in the second power supply cable 27, are able to cancel out the electromagnetic noise that has been superimposed on both of the connecting cables 27B and 27C at the portions adjacent to each other, so that it is possible to reduce the electromagnetic noise that has been superimposed on the second power supply cable 27.

[0052] (Relevant part of outdoor unit) Furthermore, the outdoor unit 1 according to the embodiment includes, as illustrated in FIG. 3 and FIG. 7, a pipe 37 through which a refrigerant circulating the air conditioner flows. The pipe 37 is connected to a compressor and a heat exchanger. As illustrated in FIG. 1 and FIG. 3, the electrical component module 6 according to the embodiment is arranged, along the second direction Y, at one end portion of the interior portion of the casing 7, which is included in the outdoor unit 1 in the first direction X. Furthermore, the electrical component module 6 includes, as illustrated in FIG. 3 and FIG. 7, a temperature sensor 38 that is provided on an outer peripheral surface of the pipe 37 in the interior portion of the casing 7 and that detects a temperature of a refrigerant, and a sensor cable 39 that is connected to the secondary side circuitry 14B, which is included in the first power supply circuitry 14 provided on the control board 11, and that is extended to the temperature sensor 38.

[0053] As illustrated in FIG. 3, the primary side circuitry 14 provided on the control board 11, and the primary side circuitry 17A, which is included in the second power supply circuitry 17 provided on the communication board 12, are arranged on one end portion side of the interior portion of the casing 7 in the first direction X. The sensor cable 39 is extended from the secondary side circuitry 14B side of the control board 11 to the temperature sensor 38, by passing through the secondary side circuitry 17B side of the communication board 12, in the first direction X of the interior portion of the casing 7.

[0054] As a result of the sensor cable 39 being arranged in this way, the sensor cable 39 is disposed away from the primary side circuitry 14A, which is provided on the control board 11, and the primary side circuitry 17A, which is provided on the communication board 12, that correspond to the noise source, so that it is possible to suppress the electromagnetic noise that is emitted from both of the first power supply circuitry 14, which is provided on the control board 11, and the second power supply circuitry 17, which is provided on the communication board 12, from being superimposed on the sensor cable 39.  As a result of this, it is possible to enhance the accuracy of detection obtained by the temperature sensor 38, and it is possible to appropriately control the air conditioner by using the electrical component module 6 on the basis of the detection result obtained by the temperature sensor 38.

[0055] (Effects of embodiment) As described above, the electrical component module 6 according to the embodiment includes the control board 11 that has the control circuitry 13 and the first power supply circuitry 14, the communication board 12 that has circuitry 17, the first power supply cable 26 that supplies electric power to the first power supply circuitry 14, which is provided on the control board 11, the second power supply cable 27 that supplies electric power to the second power supply circuitry 17, which is provided on the communication board 12, the communication cable 28 that is connected to the communication circuitry 16, which is provided on the communication board 12, the fixed plate 21 to which the control board 11 is fixed, and the partition plate 22 that is arranged on the fixed plate 21 side by side with the control board 11 and that partitions the interior space of the electrical component module 6 into the upper section portion 23U and the lower section portion 23L. Furthermore, in the electrical component module 6, the communication board 12 is arranged at one of the section portions (the upper section portion 23U) of the upper section portion 23U and the lower section portion 23L, the first power supply cable 26 is connected to the first power supply circuitry 14, which is provided on the control board 11, by passing through the other section portion (the lower section portion 23L), the second power supply cable 27 is connected to the second power supply circuitry 17, which is provided on the communication board 12, by passing through the other section portion (the lower section portion 23L), and the communication cable 28 is connected to the communication circuitry 16, which is provided on the communication board 12, by passing through the other section portion (the lower section portion 23L).

[0056] As described above, in the electrical component module 6 according to the embodiment, the electromagnetic noise is generated from both of the first power supply circuitry 14, which is provided on the control board 11, on the communication board 12, so that the electromagnetic noise is likely to be superimposed on the first power supply cable 26, the second power supply cable 27, and the communication cable 28, that is, the electrical component module 6 according to the embodiment has a structure in which the superimposed electromagnetic noise tends to increase. Even with this configuration, the electrical component module 6 is able to block the electromagnetic noise that is superimposed on the first power supply cable 26, the second power supply cable 27, and the communication cable 28, by the partition plate 22 having the conductive property, so that it is possible to suppress each of the cables 26, 27, and 28 from being affected by the electromagnetic noise. As a result of this, according to the embodiment, it is possible to prevent malfunction of the electrical component module 6 caused by the electromagnetic noise. Furthermore, according to the embodiment, it is possible to suppress the electromagnetic noise that has been superimposed on the first power supply cable 26 and the second power supply cable 27 from flowing outside of the outdoor unit 1, and it is possible to suppress an adverse effect on the electronic device, which is provided an outside of the outdoor unit 1.

[0057] Furthermore, in the electrical component module 6 according to the embodiment, the one section portion, which is provided by the partition plate 22, is the upper section portion 23U, and the other section portion, which is provided by the partition plate 22, is the lower section portion 23L. In other words, in the electrical component module 6, the first power supply cable 26, the second power supply cable 27, and the communication cable 28 are arranged in the lower section portion 23L, and the portion 23U.  As a result of this, it is possible to appropriately suppress, by the partition plate 22 having the conductive property, the electromagnetic noise that is generated from both of the first power supply circuitry 14, which is provided on the control board 11, and the second power supply circuitry 17, which is provided on the communication board 12 and is arranged in the upper section portion 23U, from being imposed on the first power supply cable 26, the second power supply cable 27, and the communication cable 28, which are arranged in the lower section portion 23L. Furthermore, it is possible to make installation work easier in a case where the communication board 12 is added to the electrical component module 6 retroactively.

[0058] Furthermore, in the electrical component module 6 according to the embodiment, the power supply terminal block 31 and the communication terminal block 33 are provided on the fixed plate 21, and are disposed alongside the control board 11 in the second direction Y, and are arranged side by side in the first direction X of the lower section portion 23L.  The primary side circuitry 17A and the secondary side circuitry 17B, which are included in the second power supply circuitry 17 provided on the communication board 12, are separately arranged with respect to the first direction X along the mounting surface 12a of the communication board 12. Then, in the electrical component module 6, the power supply terminal block 31 and the primary side circuitry 17A, which is provided on the communication board 12, are arranged on the same side in the first direction X, and the communication terminal block 33 and the secondary side circuitry 17B, which is provided on the communication board 12, are arranged on the same side in the first direction X. As a result of this, it is possible to avoid each of the second power supply cable 27 and the communication cable 28, which is connected to the communication board 12, from being wired in an intersecting manner each other at the lower section portion 23L, which is provided by the partition plate 22, so that, for example, it is possible to suppress the electromagnetic noise, sent from the second power supply cable 27, from being superimposed on the communication cable 28, by avoiding the communication cable 28 from being intersected with the second power supply cable 27, in which the electromagnetic noise received from the outside of the outdoor unit 1 is likely to be superimposed. As a result of this, it is possible to prevent malfunction of the electrical component module 6 caused by the electromagnetic noise.

[0059] Furthermore, in the electrical component module 6 according to the embodiment, the control board 11 and the communication board 12 are arranged side by side in the second direction Y that is perpendicular to the first direction X. The primary side circuitry 14A and the secondary side circuitry 14B, which are included in the first power supply circuitry 14 provided on the control board 11, are separately arranged with respect to the first direction X along the mounting surface 11a (11b) of the control board 11. Then, in the electrical component module 6, the secondary side circuitry 14B, which is provided on the control board 11, and the secondary side circuitry 17B, which is provided on the communication board 12, are connected by the communication cable 28, and the power supply terminal block 31 and the primary side circuitry 14A, which is provided on the control board 11, are arranged on the same side in the first direction X, and the circuitry 14B, which is provided on the control board 11, are arranged on the same side in the first direction X. As a result of this, it is possible to avoid each of the first power supply cable 26 and the communication cable 28, which is connected to the control board 11, from being wired in an intersecting manner each other at the lower section portion 23L, which is provided by the partition plate 22, and a portion between the communication board 12 and the control board 11, so that it is possible to suppress the electromagnetic noise, sent from the first power supply cable 26, from being superimposed on the communication cable 28. As a result of this, it is possible to prevent malfunction of the electrical component module 6 caused by the electromagnetic noise.

[0060] Furthermore, the partition plate 22 included in the electrical component module 6 according to the embodiment, is formed such that the control board 11 side of the supporting surface 22a, which supports the communication board 12, is inclined in a direction in which the lower section portion 23L decreases in the second direction Y, and the communication board 12 is arranged at a position closer to the control board 11 side on the supporting surface 22a. As a result of this, it is possible to arrange the electronic component group 24 that has been mounted on the mounting surface 12a of the communication board 12, closer to the control board 11 side on the supporting surface 22a, and it is thus possible to reduce a protrusion amount of the electronic component group 24 protruding in the Z direction corresponding to the third direction that is perpendicular to the X-Y plane. For this reason, it is possible to secure a large gap between the electronic component group 24, provided on the 7, so that, for example, it is possible to prevent damage to the communication board 12 by avoiding a collision between the electronic component group 24 and the casing 7.

[0061] Furthermore, in the electrical component module 6 according to the embodiment, on the mounting surface 12a that is provided on the communication board 12 and that is located on the side opposite to the supporting surface 22a of the partition plate 22, the maximum protrusion amount H1 of the electronic component group 24, which is arranged on one end portion disposed on the control board 11 side and which protrudes from the mounting surface 12a, is larger than the maximum protrusion amount H2 of the electronic component group 24, which is arranged on the other end portion located on the side opposite to the control board 11 side and which protrudes from the mounting surface 12a. As a result of this, on the mounting surface 12a of the communication board 12, it is possible to further suppress a protrusion amount of the electronic component group 24 protruding in the Z direction corresponding to the third direction Z that is perpendicular to the X-Y plane, so that it is possible to further secure a gap between the electronic component group 24 and the inner surface of the casing 7, and as a result of this, for example, it is possible to enhance the effect of preventing damage to the communication board 12 by avoiding a collision between the electronic component group 24 and the casing 7.

[0062] Furthermore, on the fixed plate 21 included in the electrical component module 6 according to the embodiment, the terminal block supporting surface 21a, on which the power supply terminal block 31 and the communication terminal block 33 are arranged, is formed such that the control board 11 side of the terminal block supporting surface 21a, is inclined so as to be away from the supporting surface 22a of the partition plate 22. As a result of this, it is possible to secure the space that is located between the terminal block supporting surface 21a and the partition plate 22 and that forms the lower section portion 23L, so that it is possible to avoid the lower section portion 23L from becoming narrow in accordance with the inclination of the supporting surface 22a of the partition plate 22, and it is thus possible to easily wire the first power supply cable 26, the second power supply cable 27, and the communication cable 28 in the lower section portion 23L.

[0063] Furthermore, the relay terminal block 32 included in the electrical component module 6 according to the embodiment, is arranged side by side with the power supply terminal block 31 in the first direction X of the lower section portion 23L, and the second power supply cable 27 is extended from the relay terminal block 32 toward the power supply terminal block 31 side, and is connected to the mounting surface 12a of the communication board 12 at the same position as the position of the power supply terminal block 31 with respect to the first direction X when viewed from the mounting surface 12a of the communication board 12. As a result of this, a portion, in which the second power supply cable 27 (the connecting cable 27C), extending from the relay terminal block 32 to the mounting surface 12a of the communication board 12, and the second power supply cable 27 (the connecting cable 27B), extending from the power supply terminal block 31 to the relay terminal block 32, are arranged adjacent to each other, is present.  For this reason, it is possible to cancel out the electromagnetic noise that has been superimposed on the second power supply cable 27 at the portion, in which the cables are arranged adjacent to each other, so that it is possible to reduce the electromagnetic noise that has been superimposed on the second power supply cable 27.

[0064] Furthermore, the partition plate 22 included in the electrical component module 6 according to the embodiment, is constituted such that the end portion of the supporting surface 22a that supports the communication board 12 and that is located on the control board 11 side extends toward the lower section portion 23L side.  As a result of this, in particular, the electromagnetic noise, generated from the first power supply circuitry 14 provided on the control board 11, is suppressed from entering the interior of the lower section portion 23L from the control board 11 side disposed in the lower section portion 23L, so that it is possible to suppress the electromagnetic noise, emitted from the control board 11, from being superimposed on the first power supply cable 26, the second power supply cable 27, and the communication cable 28 that are arranged in the lower section portion 23L.

[0065] Furthermore, the outdoor unit 1 according to the embodiment includes the casing 7, in which the electrical component module 6 is arranged along the second direction Y at one end portion of the interior portion in the first direction X. In the outdoor unit 1, the primary side circuitry 14A, which is provided on the control board 11, and the primary side circuitry 17A, which is provided on the communication board 12, are arranged on one end portion side of the casing 7 in the first direction X, and the sensor cable 39 is extended from the secondary side circuitry 14B side of the control board 11 to the temperature sensor 38 in the first direction X of the interior portion of the casing 7, by passing through the secondary side circuitry 17B side of the communication board 12. As a result of this, the sensor cable 39 is arranged away from the primary side circuitry 14A, which is provided on the control board 11, and the primary side circuitry 17A, which is provided on the communication board 12, that correspond to the noise source, so that it is possible to suppress the electromagnetic noise that is emitted from both of the first power supply circuitry 14, which is provided on the control board 11, and the second power supply circuitry 17, which is provided on the communication board 12, from being superimposed on the sensor cable 39. As a result of this, it is possible to enhance the accuracy of detection, obtained by the temperature sensor 38, and it is possible to appropriately control the air conditioner by using the electrical component module 6 on the basis of the detection result, obtained by the temperature sensor 38 Reference Signs List
