Description

[0001] This application is based on Japanese Patent Application No. 2023-212197 (filing date: December 15, 2023), and claims priority based on this application. This application incorporates the entire contents of that application by reference. Technical Field

[0002] An embodiment of the present invention relates to an air conditioner. Background Art

[0003] Conventionally, various air conditioners have been used corresponding to a desired air-conditioning target space. For example, in an elevator, an air conditioner is provided in the ceiling portion of a car to perform cooling and heating inside the car. Such an elevator air conditioner sometimes uses a refrigeration cycle and is configured to have an indoor unit and an outdoor unit in one housing.

[0004] In this case, since the outdoor unit and the indoor unit are mixed in one housing, it is necessary to improve the workability of ensuring the ventilation path for these units in the housing, as well as the routing and connection of wiring and piping.

[0005] In addition, for example, the housing of this air conditioner has a rectangular parallelepiped shape, and an intake port and an exhaust port (hereinafter collectively referred to as intake / exhaust ports) of the indoor unit are provided on the side surface and the lower surface of the housing, respectively. When installing the air conditioner, usually, either the intake / exhaust port on the side surface or the lower surface of the housing is appropriately selected for use. However, even with such selectable intake / exhaust ports, both the intake / exhaust port on the side surface and the lower surface of the housing can be used.

[0006] However, in this case, one pipe is required for each intake / exhaust port, that is, a total of four pipes are required, and piping work for these pipes is necessary. Summary of the Invention

[0007] The problem to be solved by the present invention is to provide an air conditioner that can appropriately ensure the ventilation path for the outdoor unit and the indoor unit in the housing, as well as the routing and connection of wiring and piping, and can achieve the high efficiency of these required operations.

[0008] An air conditioner according to an embodiment includes an outdoor unit, a control unit, and a housing. The outdoor unit has a compressor that compresses a refrigerant, an outdoor heat exchanger that exchanges heat between outdoor air and the refrigerant, and an outdoor blower that takes in the outdoor air and blows out the air that has undergone heat exchange in the outdoor heat exchanger to the outside. The control unit controls the operations of the compressor and the outdoor blower. The housing houses the outdoor unit and the control unit, and has an intake port for taking in the outdoor air and an outlet port for blowing out the air that has undergone heat exchange in the outdoor heat exchanger to the outside. The control unit has a substrate on which electrical components are mounted, a terminal block provided with terminals, and a heat sink that contacts the electrical components mounted on the substrate and releases the heat generated by the electrical components. The terminals are connected to wiring that is connected to the substrate. The housing has a first plate member that stands up on the opposite side of the intake port across the heat sink inside. The first plate member has a through portion that guides the air taken in from the intake port through the heat sink to the outdoor heat exchanger.

[0009] According to the air conditioner having the above configuration, it is possible to appropriately ensure the ventilation paths for the outdoor unit and the indoor unit inside the housing, and to efficiently perform operations such as routing and connecting the wiring and piping, thereby achieving the high efficiency of these required operations.

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The use of the air conditioner of the present invention is not particularly limited. In the present embodiment, an air conditioner for conditioning the air inside the car of an elevator will be described as an example. In the following description, the inside of the car of the elevator is referred to as the indoor area, and the outside of the car, such as the elevator shaft (Japanese: shojo-jiro), is referred to as the outdoor area.

[0022] (First embodiment)

[0023] Figure 1 It is a diagram showing an example of the installation method of the air conditioner 1 of the first embodiment. As Figure 1 shown, the air conditioner 1 is installed above the ceiling portion 920 of the car 910 of the elevator 900. A space for piping the pipes connected to the air conditioner 1 is provided between the air conditioner 1 and the ceiling portion 920. The pipes are, for example, in a pair and connect between the air conditioner 1 and the inside of the car 910, guide the air inside the car 910 to the air conditioner 1, and supply the air whose temperature has been adjusted by the air conditioner 1 to the inside of the car 910. Thus, the air inside the car 910 is conditioned. The user enters the inside of the car 910 through the door 911 provided on the front of the car 910, and the elevator 900 moves the car 910 up and down. One end of the wire 930 that can be wound by a traction machine (not shown) of the car 910 is connected to the ceiling portion 920. The other end of the wire 930 is connected to a counterweight (not shown) that moves up and down along the guide rail. Thus, by winding or feeding out the wire 930 with the traction machine, the car 910 moves up and down while being balanced by the counterweight.

[0024] Figure 2 It is a perspective view schematically showing the configuration of the air conditioner 1. Figure 3 It is a top view schematically showing the configuration of the air conditioner 1. In Figure 2 and Figure 3 part of the top plate portion and side wall portion of the housing described later are omitted.

[0025] As Figures 1 to 3 shown, the air conditioner 1 includes an outdoor unit 20, an indoor unit 40, and a housing 60. The outdoor unit 20 and the indoor unit 40 are housed together in a common housing 60 and are connected by a flow path through which refrigerant flows. In the present embodiment, the air conditioner 1 appropriately switches between cooling operation and heating operation to cool or heat the desired interior of the space to be air-conditioned, here the interior of the elevator 900 car 910.

[0026] The outdoor unit 20 has a compressor 21, an outdoor heat exchanger 22, an outdoor blower 23, an outdoor controller 24, etc. as main elements. In addition to these, the outdoor unit 20 appropriately has, for example, a four-way valve, an expansion valve, a temperature detector, a pressure detector, etc.

[0027] The compressor 21 sucks refrigerant from a suction pipe (not shown) and compresses it, discharging the compressed refrigerant to a discharge pipe 21a. For example, the compressor 21 is configured to include a sealed container, a rotating shaft, a compression mechanism, a motor structure, etc., and discharges high-temperature, high-pressure gaseous refrigerant to the discharge pipe 21a. In the compressor 21, the gaseous refrigerant separated by a reservoir (suction cup) 21b is sucked from the suction pipe into the compression mechanism.

[0028] The outdoor heat exchanger 22 exchanges heat between the air outside, here the outside of the elevator 900 car 910, and the refrigerant. The outdoor heat exchanger 22 functions as a condenser, for example, when the air conditioner 1 is in cooling operation, and functions as an evaporator when the air conditioner 1 is in heating operation. The outdoor heat exchanger 22 is composed of, for example, heat conduction pipes erected in a specified direction through which refrigerant flows and a plurality of fins thermally connected to the heat conduction pipes. In the illustrated example, two outdoor heat exchange portions 22a, 22b form a group to constitute the outdoor heat exchanger 22. The heat conduction pipes of these outdoor heat exchange portions 22a, 22b are continuous at a bent portion in two linear portions when viewed from above, and the whole is substantially L-shaped. The outdoor heat exchange portion 22a and the outdoor heat exchange portion 22b are arranged to be substantially point-symmetrical.

[0029] The outdoor blower 23 takes in the outside air (hereinafter also referred to as external air) and blows the air that has exchanged heat in the outdoor heat exchanger 22 to the outside. The outdoor blower 23 is configured as, for example, a propeller fan including a fan motor 231 and blades 233 mounted on the rotating shaft 232 of the fan motor 231. The external air taken in by the outdoor blower 23 is blown to the outdoor heat exchanger 22. Thereby, heat exchange occurs between the external gas and the refrigerant flowing in the outdoor heat exchanger 22, specifically in the heat conduction pipes. The outdoor blower 23 is disposed near the outdoor heat exchanger 22.

[0030] The outdoor controller 24 controls the operations of the compressor 21, the outdoor blower 23, etc. In the present embodiment, the outdoor controller 24 and the indoor controller 43 that controls the operations of the indoor blower 42, etc. of the indoor unit 40 described later together constitute the control unit 80 of the air conditioner 1. The control unit 80 appropriately performs the start of operation, stop of operation, monitoring of the operation status, etc. of the air conditioner 1.

[0031] The indoor unit 40 has an indoor heat exchanger 41, an indoor blower 42, an indoor controller 43, etc. as main elements. In addition, the indoor unit 40 also appropriately has, for example, an expansion valve, a temperature detector, a pressure detector, etc.

[0032] The indoor heat exchanger 41 performs heat exchange between the air inside the room, here the air inside the car 910 of the elevator 900, and the refrigerant. The indoor heat exchanger 41 functions as an evaporator, for example, when the air conditioner 1 performs a cooling operation, and functions as a condenser when the air conditioner 1 performs a heating operation. The indoor heat exchanger 41 is composed of, for example, heat conduction tubes erected in a specified direction and through which the refrigerant flows, and a plurality of fins thermally connected to the heat conduction tubes.

[0033] The indoor blower 42 sucks in the air inside the room (hereinafter, also referred to as internal gas), and discharges the air that has undergone heat exchange in the indoor heat exchanger 41 into the room. The indoor blower 42 is configured as, for example, a sirocco fan having a fan motor 421 and a cylindrical multi-wing fan 423 mounted on the rotating shaft 422 of the fan motor 421. When the multi-wing fan 423 rotates, air is sucked in from the axial direction of the rotating shaft 422 and discharged in the circumferential direction. The internal gas sucked in by the indoor blower 42 passes through the indoor heat exchanger 41. Thereby, heat exchange occurs between the internal gas and the refrigerant flowing in the indoor heat exchanger 41. The indoor blower 42 is disposed near the indoor heat exchanger 41.

[0034] The indoor controller 43 controls the operations of the indoor blower 42, etc. In the present embodiment, the indoor controller 43 and the outdoor controller 24 that controls the operations of the compressor 21, the outdoor blower 23, etc. of the outdoor unit 20 together constitute the control unit 80 of the air conditioner 1.

[0035] The housing 60 houses the outdoor unit 20, the indoor unit 40, and the control unit 80, and constitutes the main body portion of the air conditioner 1. In the present embodiment, the outer shape of the housing 60 is substantially rectangular parallelepiped, and has a bottom plate portion 61, a top plate portion 62, and a plurality of (here, four) side wall portions 63, 64, 65, 66. The materials of these bottom plate portion 61, top plate portion 62, and side wall portions 63, 64, 65, 66 are not particularly limited. In the present embodiment, as an example, these portions are formed of sheet metal, but all or part of them may be made of resin, etc., as long as they have the desired strength.

[0036] As an example, the bottom plate portion 61 and the top plate portion 62 are in a substantially planar shape along the horizontal plane, and the four side wall portions 63, 64, 65, and 66 are in a substantially planar shape along the vertical plane that stands perpendicular to the horizontal plane. The housing 60 is arranged such that the bottom plate portion 61 and the top plate portion 62 are substantially parallel to the ceiling portion 920 of the car 910 of the elevator 900.

[0037] The outdoor unit 20, the indoor unit 40, and the control unit 80 are arranged on the bottom plate portion 61. Figure 3 In the example shown, in the bottom plate portion 61, the outdoor unit 20 is arranged in the substantially right half portion, the indoor unit 40 is arranged in the substantially upper left portion, and the control unit 80 is arranged in the substantially lower left portion. However, these arrangements are not limited to the illustrated example. As described later, the bottom plate portion 61 is provided with a first air intake port 611 (refer to Figure 6 ) for sucking the air in the room and a first air outlet port 612 (refer to Figure 6 ) for supplying the air that has undergone heat exchange in the indoor heat exchanger 41 to the room.

[0038] The top plate portion 62 is arranged opposite to the bottom plate portion 61. The top plate portion 62 is fixed to the side wall portions 63, 64, 65, and 66 by screws or the like, for example, and can be appropriately loaded and unloaded in the housing 60. Thus, by removing the top plate portion 62 during inspection or work, etc., it is possible to access the outdoor unit 20, the indoor unit 40, and the control unit 80 housed in the housing 60.

[0039] The side wall portions 63, 64, 65, and 66 stand up so as to surround the outdoor unit 20, the indoor unit 40, and the control unit 80 between the bottom plate portion 61 and the top plate portion 62. As described later, one of these side wall portions 63, 64, 65, and 66, the side wall portion 63 (hereinafter referred to as the first side wall portion 63), is provided with a second air intake port 631 (refer to Figure 6 ) for sucking the air in the room and a second air outlet port 632 (refer to Figure 6 ) for supplying the air that has undergone heat exchange in the indoor heat exchanger 41 to the room. The side wall portion 64 (hereinafter referred to as the second side wall portion 64) opposite to the first side wall portion 63 is provided with an air outlet port 641 (refer to Figure 1 ) for blowing out the air that has undergone heat exchange in the outdoor heat exchanger 22 to the outside. A pair of side wall portions 65 and 66 (hereinafter referred to as the third side wall portion 65 and the fourth side wall portion 66) standing between the first side wall portion 63 and the second side wall portion 64 are provided with intake ports 651 and 661 (refer to Figure 1 and Figure 2 ) for taking in the outdoor air (external air).

[0040] As described above, the control unit 80 includes the outdoor controller 24 and the indoor controller 43, and is housed in the housing 60. Figure 4 is an enlarged view Figure 2 and Figure 3 a perspective view of the vicinity of the control unit 80 in the air conditioner 1 shown in the figure.

[0041] As Figures 2 to 4 shown, the outdoor controller 24 has a substrate 241, a terminal block 242, a radiator 243, etc. as main elements. The substrate 241 is formed, for example, by mounting various electrical components on a prescribed base material, and is stored in a metal box (hereinafter referred to as the outdoor control box) 244. For example, one surface (as an example, the upper surface in the vertical direction) of the substrate 241 is the mounting surface for various electrical components, and the other surface (as an example, the lower surface in the vertical direction) is the soldering surface for these electrical components.

[0042] The terminal block 242 is configured such that terminals are provided on a prescribed base member, and the terminals are connected to the wiring connected to the substrate 241. In the present embodiment, a terminal group composed of a plurality of terminals connected to the wiring group is provided corresponding to the wiring group composed of a plurality of wirings.

[0043] In the illustrated example, the terminal block 242 has, in addition to the wiring group connected to the substrate 241 of the outdoor controller 24, a terminal group composed of a plurality of terminals connected to the wiring group corresponding to the wiring group connected to the substrate 431 of the indoor controller 43. That is, not only the outdoor controller 24, but the terminal block 242 also serves as the terminal block for the indoor controller 43. The substrate 431 of the indoor controller 43 is formed, like the substrate 241 of the outdoor controller 24, by mounting various electrical components on a prescribed base material, and is stored in a metal box (hereinafter referred to as the indoor control box) 432.

[0044] The radiator 243 is a cooler that releases the heat generated in the substrate 241 of the outdoor controller 24. The radiator 243 is made of aluminum or the like with excellent heat transfer characteristics, and includes a heat transfer portion 243a that contacts the electrical components mounted on the mounting surface of the substrate 241 and a heat dissipation portion 243b provided on the heat transfer portion 243a. In the radiator 243, the heat transfer portion 243a corresponds to the root (closed portion), and the heat dissipation portion 243b corresponds to the open portion.

[0045] In the present embodiment, the heat transfer portion 243a is in the form of a plate that contacts the heat dissipation surface of the electrical components mounted on the substrate 241, particularly the heat generating components, and the heat dissipation portion 243b is a plurality of fins standing up at a prescribed interval from the heat transfer portion 243a. The heat transfer portion 243a only needs to be thermally connected to the heat dissipation surface of the heat generating components in the substrate 241, and the contact method with the heat dissipation surface is not limited.

[0046] For example, the heat transfer part 243a is in direct contact with the heat dissipation surface of the heat generating component mounted on the substrate 241. The heat dissipation part 243b erects a plurality of fins from the opening formed in a part of the outdoor control box 244 toward the outside of the outdoor control box 244, and a part or the whole of each fin is exposed to the outside of the outdoor control box 244. However, the forms of the heat transfer part 243a and the heat dissipation part 243b are not limited to this. For example, the heat dissipation part 243b may not be a plate-shaped fin but a rod-shaped protrusion or the like.

[0047] The radiator 243 is disposed near the outside air intake port 651 (refer to Figure 1 ) of the third side wall part 65. In the illustrated example, the radiator 243 is disposed such that the plane defined by the respective fins of the heat dissipation part 243b is substantially orthogonal to the third side wall part 65. Thus, the outside air taken in from the intake port 651 can smoothly pass between the adjacent fins of the heat dissipation part 243b formed by the plurality of fins.

[0048] The outdoor controller 24 further includes a plate-shaped member (hereinafter referred to as the second plate member with respect to the first plate member 67 of the housing 60 described later) 25 on which the terminal block 242 is disposed. The second plate member 25 has a first plate portion 25a on which the terminal block 242 is disposed, a second plate portion 25b that covers the open portion of the radiator 243, that is, the heat dissipation part 243b, and a third plate portion 25c that connects between the first plate portion 25a and the second plate portion 25b.

[0049] The first plate portion 25a extends in a substantially rectangular planar shape corresponding to the size of the terminal block 242. The second plate portion 25b is substantially parallel to the first plate portion 25a, extends in a planar shape at a predetermined interval from the front end of the heat dissipation part 243b, and covers the front end. The front end of the heat dissipation part 243b is the erected end of the heat dissipation part 243b that erects from the heat transfer part 243a. The third plate portion 25c erects from one edge of the first plate portion 25a and is continuous with the second plate portion 25b. Thus, the second plate portion 25b raises the erected height of the third plate portion 25c by an amount. The erected height of the third plate portion 25c, that is, the raised height of the second plate portion 25b from the first plate portion 25a, is adjusted to a height at which the second plate portion 25b can face the front end at a predetermined interval from the front end of the heat dissipation part 243b.

[0050] The second plate portion 25b covers the open portion of the radiator 243, that is, the front end of the heat dissipation portion 343b, through the plate surface 251 of one of the two plate surfaces as the main surface. In contrast, the second plate portion 25b has a wiring fixing portion (hereinafter referred to as the second wiring fixing portion relative to the first wiring fixing portion 671 of the first plate member 67 described later) 253 for fixing the wiring on the plate surface 252 on the opposite side of the plate surface 251. The second wiring fixing portion 253 is connected to the terminal group of the terminal block 242 and fixes the wiring group connected to the substrate 241 of the outdoor controller 24 and the substrate 431 of the indoor controller 43.

[0051] The material and form of the second wiring fixing portion 253 are not particularly limited. In the example shown in the figure, the second wiring fixing portion 253 is configured as a component different from the second plate portion 25b and is mounted on the plate surface 252 of the second plate portion 25b. The second wiring fixing portion 253 of the example shown in the figure is a fixing member formed of an elastic resin material or a metal material, and has a base 254 extending in a predetermined direction and a pair of claws 255 that stand up from both ends of the base 254 and are bent in a manner such that the front ends are close to each other. Thus, the second wiring fixing portion 253 holds the wiring in a manner of holding it between the base 254 and the pair of claws 255.

[0052] The second wiring fixing portion 253 is installed on the second plate portion 25b, for example, by inserting a mounting protrusion provided on the base 254 into a mounting hole that penetrates the second plate portion 25b, and hooking the barb (Japanese: 返し) of the mounting protrusion on the peripheral portion of the mounting hole. However, the second wiring fixing portion 253 can be installed on the second plate portion 25b by any method. On the plate surface 252 of the second plate portion 25b, for example, any number of second wiring fixing portions 253 can be arranged according to the number of fixed wiring groups, etc. In the example shown in the figure, two second wiring fixing portions 253 are provided on the plate surface 252 of the second plate portion 25b.

[0053] In addition, in the present embodiment, the frame 60 includes an inlet 651 (see FIG. 1 ) formed in the third side wall portion 65 via the heat sink 243. Figure 1 ) is a plate-shaped member (hereinafter referred to as the first plate member relative to the second plate member 25 of the outdoor controller 24) 67. The first plate member 67 is formed of, for example, sheet metal, and stands relative to the bottom plate portion 61. The first plate member 67 separates the configuration space of the indoor unit 40 from the configuration space of the control unit 80 in the space surrounded by the bottom plate portion 61, the top plate portion 62, and the four side wall portions 63, 64, 65, 66, i.e., inside the frame 60. In other words, the first plate member 67 is arranged in the vicinity of the indoor unit 40 and the control unit 80 inside the frame 60.

[0054] The first plate member 67 stands upright substantially parallel to the third side wall portion 65 of the housing 60, specifically, its access port 651. In other words, the first plate member 67 stands upright in a manner substantially orthogonal to the plane defined by the fins of the heat dissipation portion 243b respectively. The first plate member 67 has a wiring fixing portion (hereinafter, referred to as the first wiring fixing portion as opposed to the second wiring fixing portion 253 of the second plate portion 25b) 671 for fixing wiring at its upright end (hereinafter, referred to as the front end of the first plate member 67). The first wiring fixing portion 671 is connected to the terminal group of the terminal block 242 and fixes the wiring group connected to the substrate 241 of the outdoor controller 24 and the substrate 431 of the indoor controller 43.

[0055] The material and form of the first wiring fixing portion 671 are not particularly limited. In the illustrated example, the first wiring fixing portion 671 is configured as a member different from the first plate member 67 and is mounted at the front end of the first plate member 67. The first wiring fixing portion 671 in the illustrated example is a fixing member formed of an elastic resin material or a metal material, and has a base 672 extending in a specified direction and a pair of claws 673 that stand up from both ends of the base 672 and are bent in such a way that their front ends approach each other. Thus, the first wiring fixing portion 671 holds the wiring in a manner of sandwiching the wiring between the base 672 and the pair of claws 673.

[0056] The first wiring fixing portion 671 is mounted on the first plate member 67, for example, by inserting the mounting grooves provided in the base 672 and the claws 673 into the peripheral portion of the cutout formed in the first plate member 67. However, the method of mounting the first wiring fixing portion 671 to the first plate member 67 can be any method. For example, any number of first wiring fixing portions 671 can be arranged on the first plate member 67 according to the number of the fixed wiring groups, etc. In the illustrated example, two first wiring fixing portions 671 are provided on the first plate member 67. The number of the first wiring fixing portions 671 can be the same as or different from the number of the second wiring fixing portions 253.

[0057] Figure 5 It is a diagram showing an example of the wiring method of the wiring group fixed by the second wiring fixing portion 253 and the first wiring fixing portion 671 in the air conditioner 1. As Figure 5 shown, the terminal block 242 of the present embodiment has three terminal groups, namely, a first terminal group 31, a second terminal group 32, and a third terminal group 33. These terminal groups 31, 32, and 33 each include a plurality of terminals.

[0058] A plurality of wirings (power supply lines) 51 connected to an external power supply line (not shown) of the air conditioner 1 are connected to the first terminal group 31. The substrates 241 of the outdoor controller 24 and the substrates 431 of the indoor controller 43 are supplied with power from these power supply lines 51. A plurality of wirings 52 connected to the substrate 431 of the indoor controller 43 are connected to the second terminal group 32. For example, by switching the connection presence or absence of the wiring 52 with respect to the second terminal group 32, the functions of the air conditioner 1 can be switched. A plurality of control lines different from the plurality of wirings 52, that is, a plurality of wirings 53 connected to the substrate 431 of the indoor controller 43, are connected to the third terminal group 33. These wirings 53 are, for example, control lines for controlling a remote controller of the air conditioner 1 and are connected to the remote controller (not shown) via the third terminal group 33. The remote controller can be wireless or wired.

[0059] One of the two second wiring fixing parts 253, the second wiring fixing part 253a, fixes the plurality of wirings 52 connected to the second terminal group 32 together. In contrast, the other second wiring fixing part 253b fixes the plurality of wirings 52 connected to the second terminal group 32 and the plurality of wirings 53 connected to the third terminal group 33 together.

[0060] One of the two first wiring fixing parts 671, the first wiring fixing part 671a, fixes the wiring 54 connected to the substrate 431 of the indoor controller 43. The wiring 54 is connected to, for example, the indoor blower 42 or the like. In contrast, the other first wiring fixing part 671b fixes the wiring 55 connected to the substrate 241 of the outdoor controller 24. The wiring 55 is connected to, for example, the compressor 21 or the like.

[0061] As Figure 2 and Figure 4 shown, in addition to the first wiring fixing part 671, the first plate member 67 has a through-hole 674 that penetrates the first plate member 67. The through-hole 674 is a flow path for guiding the air (external air) taken in from the intake port 651 of the third side wall part 65 (refer to Figure 1 ) to the outdoor heat exchanger 22. The through-hole 674 penetrates the first plate member 67 at a position facing the heat dissipation part 243b of the radiator 243 in the plate thickness direction of the first plate member 67. That is, the through-hole 674 penetrates the first plate member 67 within a range substantially covering the entire existence area of the heat dissipation part 243b on a specified plane viewed from the intake port 651 of the third side wall part 65. The specified plane is a plane along the third side wall part 65 and is a plane substantially orthogonal to the plane defined by the fins of each heat dissipation part 243b.

[0062] When the outdoor blower 23 of the outdoor unit 20 is operated, the outside air is taken into the frame 60 from the inlet 651 of the third side wall portion 65, and the taken-in outside air passes through the heat dissipation portion 243b and the through portion 674. Then, the outside air passing through the through portion 674 is guided to the outdoor heat exchanger 22.

[0063] Thus, according to the air conditioner 1 of the present embodiment, in the control unit 80, the terminal block 242 of the outdoor controller 24 is arranged on the second plate member 25. The second plate member 25 has the second plate portion 25b covering the heat dissipation portion 243b which is the open portion of the radiator 243. Therefore, a predetermined plane portion can be generated in the range where the second plate portion 25b extends above the heat dissipation portion 243b of the radiator 243 which is an open space in the past.

[0064] Thus, the specified wiring can be routed and routed on the second plate portion 25b. For example, the plurality of wirings 52 and 53 connected to the substrate 431 of the indoor controller 43 can be routed on the second plate portion 25b. Therefore, the heat generated in the substrate 241 of the outdoor controller 24 can be released by the radiator 243 to cool the substrate 241, and the wirings 52 and 53 can be efficiently routed in the narrow space inside the frame 60.

[0065] In addition, the second plate portion 25b has a second wiring fixing portion 253. Therefore, for example, the plurality of wires 52 and 53 connected to the terminal group of the terminal block 242 can be bundled and fixed by the second wiring fixing portion 253. Thus, it is possible to prevent these wires 52 and 53 from moving around on the second plate portion 25b, and to properly wire them.

[0066] Furthermore, the frame 60 includes a first plate member 67 that stands upright in the vicinity of the control unit 80. The first plate member 67 has a first wiring fixing portion 671. Therefore, for example, the wirings 54 and 55 connected to the terminal group of the terminal block 242 can be fixed by the first wiring fixing portion 671. Thus, it is possible to prevent these wirings 54 and 55 from moving around in the vicinity of the control unit 80, and to properly wire them.

[0067] That is, by providing the second wiring fixing portion 253 and the first wiring fixing portion 671 , the wirings 52 to 55 can be appropriately wired inside the housing 60 , and the degree of freedom of wiring can be increased.

[0068] In addition, the first plate member 67 stands upright in a manner substantially orthogonal to the access port 651 of the housing 60 and substantially orthogonal to the plane defined by the fins of the heat dissipation portions 243b of the radiator 243, and has a through portion 674. Therefore, the outside air taken in from the access port 651 of the housing 60 can smoothly pass between the adjacent fins of the heat dissipation portion 243b formed by a plurality of fins. Moreover, the outside air that has passed through the heat dissipation portion 243b can be guided to the outdoor heat exchanger 22 through the through portion 674. As a result, the outside air can be efficiently blown to the outdoor heat exchanger 22.

[0069] In the present embodiment, the outdoor heat exchange portions 22a and 22b of the outdoor heat exchanger 22 are continuous at the bent portion in two linear portions when viewed from above, and the whole is substantially L-shaped. Therefore, by guiding the outside air to the outdoor heat exchanger 22 through the through portion 674, for example, the outside air can also be blown to the bent portion of the outdoor heat exchange portion 22a. As a result, the heat exchange performance between the outside air and the refrigerant in the outdoor heat exchanger 22 can be improved.

[0070] As described above, according to the present embodiment, it is possible to appropriately ensure the ventilation path inside the housing 60 with respect to the outdoor unit 20 and the indoor unit 40, and to efficiently perform operations such as routing and connecting the wiring and piping, and to achieve the high efficiency of these required operations.

[0071] (Second Embodiment)

[0072] Next, the air conditioner according to the second embodiment will be described. The air conditioner according to the second embodiment is the same as the air conditioner 1 according to the first embodiment, and is configured to adjust the air inside the car 910 of the elevator 900. Therefore, the air conditioner according to the second embodiment is installed in the same manner as the installation method of the air conditioner 1 shown. In addition, in the air conditioner according to the second embodiment, the configuration other than the adapter described later is the same as that of the air conditioner 1 according to the first embodiment shown. Therefore, in the following description, for the configuration other than the adapter described later in the air conditioner according to the second embodiment, the same reference numerals as those of the air conditioner 1 are used. Figure 1 As shown, the air conditioner 10 according to the second embodiment includes 0 installed outside the housing 60. Figures 1 to 5 As shown, the configuration other than the adapter described later in the air conditioner according to the second embodiment is the same as that of the air conditioner 1 according to the first embodiment shown. Therefore, in the following description, for the configuration other than the adapter described later in the air conditioner according to the second embodiment, the same reference numerals as those of the air conditioner 1 are used.

[0073] Figure 6 is a perspective view showing a schematic configuration of the air conditioner 10 according to the second embodiment. As shown Figure 6 shown, the air conditioner 10 includes 0 installed outside the housing 60.

[0074] Figure 7 is a perspective view showing a schematic configuration of the adapter 70. Figure 8 is from a Figure 7 different viewing angle showing a schematic configuration of the adapter 70. As shown Figures 6 to 8As shown, the adapter 70 has a first face 70a along a prescribed first plane and a second face 70b along a second plane orthogonal to the first plane, and has an outer contour shape that is substantially L-shaped with these first face 70a and second face 70b as main faces. In the illustrated example, the first face 70a and the second face 70b are connected at an angle of approximately 90°.

[0075] The adapter 70 has a third face 70c parallel to the first face 70a and a fourth face 70d parallel to the second face 70b. In addition, the adapter 70 also has a fifth face 70e, a sixth face 70f, a seventh face 70g, and an eighth face 70h that connect between the first face 70a and the third face 70c and the second face 70b and the fourth face 70d. Through these first to eighth faces 70a to 70h, a prescribed space (hereinafter referred to as the internal space) 701 is formed inside the adapter 70.

[0076] In the illustrated example, the adapter 70 fixes the first face 70a along the bottom plate portion 61 of the housing 60 and fixes the second face 70b along the first side wall portion 63 of the housing 60 to the bottom plate portion 61. The fixing method of the adapter 70 can be any method. For example, the adapter 70 can be fixed to the housing 60 by screwing the third face 70c to the bottom plate portion 61. In addition, the adapter 70 can also fix the first face 70a along the bottom plate portion 61 of the housing 60 and fix the second face 70b along the first side wall portion 63 of the housing 60 to the first side wall portion 63.

[0077] The adapter 70 has an air inlet (hereinafter referred to as the third air inlet) 71 for sucking air (internal gas) in the room and an air outlet (hereinafter referred to as the third air outlet) 72 for discharging the air that has undergone heat exchange in the indoor heat exchanger 41 of the indoor unit 40 to the room.

[0078] The third air inlet 71 communicates with the first air inlet 611 and the second air inlet 631 of the housing 60. In contrast, the third air outlet 72 communicates with the first air outlet 612 and the second air outlet 632 of the housing 60. Therefore, the adapter 70 has an internal space (hereinafter referred to as the first air passage portion) 73 that communicates the third air inlet 71 with the first air inlet 611 and the second air inlet 631. In addition, the adapter 70 has an internal space (hereinafter referred to as the second air passage portion) 74 that communicates the third air outlet 72 with the first air outlet 612 and the second air outlet 632.

[0079] The first air passage portion 73 and the second air passage portion 74 are formed by being separated into two spaces by a partition portion 70i in the internal space 701 of the adapter 70. That is, one space of the internal space 701 partitioned by the partition portion 70i becomes the first air passage portion 73, and the other space becomes the second air passage portion 74.

[0080] In the present embodiment, the partition portion 70i divides the internal space 701 approximately in half. That is, the sizes (volumes) of the first air passage portion 73 and the second air passage portion 74 are approximately equal. However, the ratio of the sizes of the first air passage portion 73 and the second air passage portion 74 partitioned by the partition portion 70i is not limited to being equal. The partition portion 70i entirely closes the space between the first face portion 70a and the third face portion 70c, and between the second face portion 70b and the fourth face portion 70d, respectively.

[0081] In the illustrated example, these third intake ports 71 and third exhaust ports 72 open in the first face portion 70a, respectively. In addition, the third face portion 70c has an opening 70j that communicates with the first intake port 611 and communicates with the third intake port 71 via the first air passage portion 73. Further, the third face portion 70c has an opening 70k that communicates with the first exhaust port 612 and communicates with the third exhaust port 72 via the second air passage portion 74. The fourth face portion 70d has an opening 70l that communicates with the second intake port 631 and communicates with the third intake port 71 via the first air passage portion 73. Further, the fourth face portion 70d has an opening 70m that communicates with the second exhaust port 632 and communicates with the third exhaust port 72 via the second air passage portion 74.

[0082] In the present embodiment, the opening areas of the third intake port 71 and the third exhaust port 72 are each larger than the opening areas of the first intake port 611, the first exhaust port 612, the second intake port 631, and the second exhaust port 632. In the illustrated example, the third intake port 71 and the third exhaust port 72 are provided with substantially the same opening area. The opening areas of the third intake port 71 and the third exhaust port 72 at this time are each set as S3. The opening areas of the second exhaust port 631 and the second intake port 632 are larger than the opening areas of the first intake port 611 and the first exhaust port 612, and are provided with substantially the same opening area. The opening areas of the second exhaust port 631 and the second intake port 632 at this time are each set as S2. In this case, the opening area S3 is larger than the opening area S2 (S3 > S2). Further, in the present embodiment, the opening areas of the third intake port 71 and the third exhaust port 72 are each larger than the opening areas of the openings 70j, 70k, 70l, and 70m.

[0083] As described above, in the present embodiment, the air conditioner 10 conditions the air inside the car 910 of the elevator 900. Therefore, the third intake port 71 is connected to the intake duct 75, and the third exhaust port 72 is connected to the exhaust duct 76. The intake duct 75 guides the air inhaled from the interior of the elevator 900 (inside the car 910) to the first air passage portion 73. The exhaust duct 76 guides the air supplied to the interior of the elevator 900 from the third exhaust port 72 to the interior of the elevator 900.

[0084] The third intake port 71 has an intake duct connection portion 71a for connecting the intake duct 75. The intake duct connection portion 71a projects in a cylindrical shape from the opening peripheral edge of the third intake port 71 toward the outside of the adapter 70. Similarly, the third exhaust port 72 has an exhaust duct connection portion 72a for connecting the exhaust duct 76. The exhaust duct connection portion 72a projects in a cylindrical shape from the opening peripheral edge of the third exhaust port 72 toward the outside of the adapter 70.

[0085] Thus, in the air conditioner 10 according to the present embodiment, the adapter 70 is installed outside the housing 60. In the adapter 70, the third intake port 71 communicates with the first intake port 611 and the second intake port 631 of the housing 60 via the first air passage portion 73. In addition, the third exhaust port 72 communicates with the first exhaust port 612 and the second exhaust port 632 of the housing 60 via the second air passage portion 74.

[0086] Therefore, by connecting the intake duct 75 to the third intake port 71, the air inhaled from the interior can be guided to the first air passage portion 73 through one intake duct 75. In addition, by connecting the exhaust duct 76 to the third exhaust port 72, the air supplied to the interior can be guided from the third exhaust port 72 to the interior through one exhaust duct 76. Therefore, even when all of the first intake port 611 and the second intake port 631, and the first exhaust port 612 and the second exhaust port 632 of the housing 60 are used, only one intake duct 75 and one exhaust duct 76 are sufficient respectively. That is, it is not necessary to prepare the same number of ducts as the intake ports 611, 631 and the exhaust ports 612, 632. Therefore, the cost required for the ducts can be suppressed, and the air volume and capacity of the air conditioner 10 can be increased by using the intake ports 611, 631 and the exhaust ports 612, 632.

[0087] In addition, the adapter 70 is fixed to the bottom plate portion 61 of the housing 60 such that the first face 70a is along the bottom plate portion 61 of the housing 60 and the second face 70b is along the first side wall portion 63 of the housing 60. Further, the opening areas of the third air inlet 71 and the third air outlet 72 are each larger than the opening areas of the first air inlet 611, the first air outlet 612, the second air outlet 631, and the second air inlet 632. Therefore, for example, without increasing the size of the housing 60, the air volume and capacity of the air conditioner 10 can be increased only by installing the adapter 70.

[0088] (Third Embodiment)

[0089] Next, the air conditioner of the third embodiment will be described. In the adapter 70 of the second embodiment, the third air inlet 71 and the third air outlet 72 open in the first face 70a, respectively. Instead, the third air inlet and the third air outlet may also open in the second face 70b, respectively. Hereinafter, the third embodiment will be described in such a manner that the third air inlet and the third air outlet open in the second face 70b, respectively.

[0090] The air conditioner of the third embodiment is the same as the air conditioners 1 and 10 of the first and second embodiments, and is configured to condition the air inside the car 910 of the elevator 900. Therefore, the air conditioner of the third embodiment is installed in the same manner as the installation manner of the air conditioner 1 shown Figure 1 In addition, in the air conditioner of the third embodiment, the configuration other than the adapter described later is the same as that of the air conditioner 1 of the first embodiment shown Figures 1 to 5 and the air conditioner 10 of the second embodiment shown Figure 6 Therefore, in the following description, for the configuration other than the adapter in the air conditioner of the third embodiment, the same reference numerals as those of the air conditioners 1 and 10 are used.

[0091] Figure 9 is a perspective view showing a schematic configuration of the air conditioner 100 of the third embodiment. As shown Figure 9 the air conditioner 100 includes an adapter 700 installed outside the housing 60.

[0092] Figure 10 is a perspective view showing a schematic configuration of the adapter 700. Figure 11 is a perspective view showing a schematic configuration of the adapter 700 from a viewpoint different from Figure 10 As shown Figures 9 to 11 the basic configuration of the adapter 700 is the same as that of the adapter 70 of the second embodiment.

[0093] The positions of the third air intake port 710 and the third air exhaust port 720 of the adapter 700 are different from those of the adapter 70. The third air intake port 710 and the third air exhaust port 720 open on the second face 70b, respectively. In addition, similarly to the adapter 70, the third face 70c has an opening 70j that communicates with the first air intake port 611 and communicates with the third air intake port 710 via the first air passage portion 73. Further, the third face 70c has an opening 70k that communicates with the first air exhaust port 612 and communicates with the third air exhaust port 720 via the second air passage portion 74. The fourth face 70d has an opening 70l that communicates with the second air intake port 631 and communicates with the third air intake port 710 via the first air passage portion 73. Further, the fourth face 70d has an opening 70m that communicates with the second air exhaust port 632 and communicates with the third air exhaust port 720 via the second air passage portion 74.

[0094] In the present embodiment, the opening areas of the third air intake port 710 and the third air exhaust port 720 are each larger than the opening areas of the first air intake port 611, the first air exhaust port 612, the second air exhaust port 631, and the second air intake port 632. In the illustrated example, the third air intake port 710 and the third air exhaust port 720 have substantially the same opening area. Let the opening area of each of the third air intake port 710 and the third air exhaust port 720 at this time be S30. The opening areas of the second air exhaust port 631 and the second air intake port 632 are larger than the opening areas of the first air intake port 611 and the first air exhaust port 612, and are substantially the same as each other. Let the opening area of each of the second air exhaust port 631 and the second air intake port 632 at this time be S2. In this case, the opening area S30 is larger than the opening area S2 (S30 > S2). Further, in the present embodiment, the opening areas of the third air intake port 710 and the third air exhaust port 720 are each larger than any of the opening areas of the openings 70j, 70k, 70l, and 70m.

[0095] Similarly to the second embodiment, the air conditioner 100 of the present embodiment conditions the air inside the car 910 of the elevator 900. Accordingly, the third air intake port 710 is connected to the intake duct 75, and the third air exhaust port 720 is connected to the exhaust duct 76. The third air intake port 710 has an intake duct connection portion 710a for connecting the intake duct 75. The intake duct connection portion 710a projects in a cylindrical shape from the opening periphery of the third air intake port 710 toward the outside of the adapter 700. Similarly, the third air exhaust port 720 has an exhaust duct connection portion 720a for connecting the exhaust duct 76. The exhaust duct connection portion 720a projects in a cylindrical shape from the opening periphery of the third air exhaust port 72 toward the outside of the adapter 700.

[0096] Thus, the air conditioner 100 according to the present embodiment, similar to the second embodiment, can suppress the cost required for the pipeline and can use the suction ports 611, 631 and the exhaust ports 612, 632 to increase the air volume and capacity of the air conditioner 10. In addition, for example, without increasing the size of the housing 60, the air volume and capacity of the air conditioner 100 can be increased only by installing the adapter 700.

[0097] The configuration of the air conditioner 100 other than the adapter 700 is the same as that of the air conditioner 10 of the second embodiment shown in Figure 6 Therefore, by arbitrarily selecting the adapter 700 of the present embodiment and the adapter 70 of the second embodiment, the connection directions of the suction pipeline 75 and the exhaust pipeline 76 can be changed. Thereby, the degree of freedom in piping the suction pipeline 75 and the exhaust pipeline 76 can be increased, and the degree of freedom in installing the air conditioner 100 can also be increased.

[0098] As mentioned above, several embodiments of the present invention have been illustrated, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, changes, etc. can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention and are included in the invention described in the claims and its equivalent scope.
