[0010] A preferred embodiment of the present disclosure will be described in detail below with reference to the drawings. Note that the present embodiment described below does not unduly limit the contents of the present disclosure described in the claims, and not all of the configurations described in the present embodiment are necessarily essential to the solution of the present disclosure. Note that in the drawings, the X direction is the width direction of the air conditioner, the Y direction is the front-rear direction of the air conditioner, and the Z direction is the height direction of the air conditioner.

[0011] Fig. 1 is a perspective view showing a schematic diagram of an air conditioner according to the present disclosure. As shown in Fig. 1, the air conditioner according to the present disclosure includes a housing 10, a heat exchanger 20, an electrical box 30, and a support section 40. The configuration of each of these components will be described below.

[0012] The housing 10 includes a right side cover 11, a left side cover 12, a bottom cover 13, and a back cover 14. The housing 10 also includes a front cover and a top cover, both of which are not shown.

[0013] The front cover is a member that covers the front of the air conditioner. Front cover 11 is boat-shaped, and has a U-shape or L-shape in cross section when viewed from the side of the air conditioner.

[0014] The right side cover 11 and the left side cover 12 are members that cover the left and right surfaces of the air conditioner, respectively.

[0015] The top cover and bottom cover 13 are members that cover the top and bottom surfaces, respectively. The back cover 14 is a member that covers the back surface of the air conditioner. Note that, for the sake of convenience, the front cover and top cover are not shown in Fig. 1 in order to explain the electrical component cover, which will be described later.

[0016] The housing 10 also includes a filter guide 50. The filter guide 50 is fixed to the housing 10.

[0017] The heat exchanger 20 is disposed on the front side of the housing 10. As the heat exchanger 20, a known one can be used.

[0018] The electrical box 30 is provided in front of the heat exchanger 20, and one side in the left-right direction (+XX direction) is fixed to the housing 10. The other side of the electrical box 30 is not fixed. In FIG. 2, one side of the electrical box 30, the +X side, is fixed by a fixing portion 45, and the other side, the -X side, is not fixed. One side of the electrical box 30 is fixed via a filter guide 50. In other words, the electrical box 30 is fixed to the housing 10 via the filter guide 50. The fixing portion is fixed to the housing 10 by a screw or bolt or the like.

[0019] The electrical component box 30 has a control unit. The control unit is an example of an "electrical component" that controls the air conditioning operation.

[0020] The control unit includes a processor such as a CPU (Central Processing Unit). The control unit controls the blower fan, the driving unit of the air direction plate, the filter cleaning device, and the like provided in the air conditioner 100.

[0021] The air conditioner has a communication unit inside. The communication unit communicates wirelessly with the operation device. For example, the communication units communicate with each other via a network. The network includes, for example, the Internet, a LAN (Local Area Network), and a public telephone network. The communication performed by the communication unit 63 includes, for example, a network interface controller (NIC) that communicates according to a predetermined communication protocol, or communication conforming to a communication standard by WiFi. The predetermined communication protocol is, for example, the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol suite (i.e., the Internet Protocol Suite).

[0022] The communication unit may also include a wireless communication module that performs wireless communication. For example, the communication unit is a wireless communication module that performs short-distance wireless communication. Short-distance wireless communication is wireless communication with a communication distance of about several meters to several tens of meters. Short-distance wireless communication is, for example, infrared communication, or communication conforming to a communication standard such as Bluetooth (registered trademark) or ZigBee (registered trademark). Communication conforming to a communication standard such as Bluetooth (registered trademark) is, for example, BLE (Bluetooth (registered trademark) Low Energy).

[0023] The electrical box 30 is housed in the front of the housing 10, as shown in Fig. 2. Moreover, in the air conditioner according to the present disclosure, as shown in Figs. 1 and 2, the electrical box 30 is provided in the width direction of the housing 10 on the front side, not on the side of the housing 10. In other words, the electrical box 30 is provided so as to straddle from the right side cover 11 to the left side cover 12. By providing the electrical box 30 in the width direction of the housing 10 on the front side of the housing 10, the heat exchanger 20 can be made larger in the width direction of the housing 10, enabling heat exchange of a large amount of heat.

[0024] The support part 40 is fixed to the housing 10 and supports the other left-right side of the electrical box 30. In Fig. 2, the support part 40 supports the -X side of the electrical box 30. The support part 40 is also fixed to the housing 10 via a filter guide 50.

[0025] A gap S is provided in the left-right direction between the support portion 40 and the electrical box 30. This configuration will be described in detail below.

[0026] FIG. 3 is an enlarged view of III in FIG. 2. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3. FIG. 5 is a cross-sectional view taken along line VV in FIG. 3. As shown in FIGS. 3, 4, and 5, a gap S is provided between the support portion 40 and the electrical box 30. In FIG. 3, the gap S is provided on the -X side (left side) of the electrical box 30. The gap S may be provided on the +X side (right). In this case, the electrical box 30 is fixed by a fixing portion 45 on the -X side (left side), and a support portion is provided on the +X side (right). Also, as shown in FIG. 5, two gaps S are provided in the width direction (X direction) at different positions in the height direction (Z direction).

[0027] In order to enlarge the heat exchanger 20 of an air conditioner, the electrical unit is placed at the front and fixed at both ends, so that the electrical unit undergoes shape changes such as expansion and contraction due to temperature changes in the heat exchanger 20. At that time, stress is concentrated in the left-right direction of the electrical unit. In some cases, this can cause damage to the electrical box 30.

[0028] Therefore, the gap S provided in the air conditioner according to the present disclosure can prevent stress concentration and inhibit breakage.

[0029] Fig. 6 is a front view of the filter guide 50 before the electrical box 30 and the support part 40 are attached. Fig. 7 is an enlarged view of VII in Fig. 6. When the electrical box 30 is placed on the support part 40 shown in Figs. 6 and 7, the embodiment shown in Figs. 2 and 3 is obtained.

[0030] 3, 4, 5 and 6, support part 40 includes a lower wall 41 that supports the other side of electrical box 30 from below, in the -Z direction, a rear wall 42 that supports the other side of electrical box 30 from the rear, in the -Y direction, an upper wall 43 provided in the +Z direction, and a side wall 44 provided in the -X direction. Support part 40 is made of plastic or metal.

[0031] The air conditioner according to the present disclosure has at least a gap S between the electrical component box 30 and the side wall 44. Furthermore, the air conditioner according to the present disclosure may have a gap S between the electrical component box 30 and the upper wall 43.

[0032] The lower wall 41 supports the electrical box 30 from below so as to prevent the electrical box 30 from falling in the -Z direction in FIG.

[0033] The rear wall 42 supports the electrical box 30 from the rear side so as to prevent it from moving rearward (in the −Y direction). The electrical box 30 is supported by the surfaces of the lower wall 41 and the rear wall 42.

[0034] The electrical box 30 is supported by the support portion 40 but is not fixed by the support portion 40. Therefore, the electrical box 30 can expand and contract in the gap S in the X, Y and Z directions.

[0035] At least a part of the back surface 40a of the support portion 40 faces the heat exchanger 20. As shown in Fig. 5, the back surface 30a (-Y direction) of the electrical box 30 and the back surface 40a of the support portion 40 are located on the same plane in the front-to-rear direction (Y direction) of the air conditioner. In other words, as shown in Fig. 5, the height 30h of the back surface 30a of the electrical box 30 and the height 40h of the back surface 40a of the support portion 40 are the same. In this way, it is possible to prevent obstruction of the airflow passing through the back side of the electrical box 30.

[0036] The left-right direction (-X+X direction) is the longitudinal direction of the electrical box 30. This allows greater expansion and contraction in the longitudinal direction than in the lateral direction, so that the effects of the air conditioner according to the present disclosure can be more effectively achieved.

[0037] Also, as shown in Fig. 2, it is preferable that the circuit element 60 is mounted on only one of the electrical box 30 and the support portion 40, and that the circuit element 60 is not mounted on the other. In other words, the circuit element is mounted on only one of the electrical box and the support portion, and that the circuit element is not mounted on the other. Note that Fig. 2 shows that the circuit element 60 is mounted only on the electrical box 30. Also, the circuit element 60 is mounted on a board. This provides efficient mounting.

[0038] Moreover, it is preferable that the power supply circuit 61 is housed on one side of the electrical box 30 and is covered with a metal part. In Fig. 2, the power supply circuit 61 is housed in the electrical box 30 on one side, that is, the +X direction side. The power supply circuit 61 is covered with a metal shield and is therefore heavy. In this way, the power supply circuit 61 is provided in a location close to the fixing part 45, so that the fixing of the electrical box 30 is more stable.

[0039] Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 1. As shown in Fig. 8, the heat exchanger 20 is disposed on the front side of the housing 10. The heat exchanger 20 is disposed on the rear surface 30a of the electrical box 30. At least a part of the rear surface 40a of the support portion 40 faces the heat exchanger 20.

[0040] As described above, the air conditioner according to the present disclosure can suppress the occurrence of stress concentration in the left-right direction of the electrical box 30 arranged at the front.

[0041] Although each embodiment and each example of the present disclosure have been described in detail above, it will be readily apparent to those skilled in the art that many modifications are possible without substantially departing from the novel features and effects of the present disclosure. Therefore, all such modifications are intended to be included within the scope of the present disclosure.

[0042] For example, a term described at least once in the specification or drawings together with a different term having a broader or similar meaning may be replaced with that different term anywhere in the specification or drawings. In addition, the configuration and operation of the air conditioner are not limited to those described in each embodiment and each example of the present disclosure, and various modifications are possible.
