DETAILED DESCRIPTION

[0010] Hereinafter, the preferred embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. In addition, the present embodiment described below does not unduly limit the content of the present disclosure as described in the scope of the claims, and all of the structures described in this embodiment are not necessary as a solution for the present disclosure. In addition, in the accompanying drawings, the X direction is the width direction of the air conditioner, the Y direction is the front-to-back direction of the air conditioner, and the Z direction is the height direction of the air conditioner.

[0011] Figure 1 It is a front view which schematically shows the air conditioner 100 of this indication. Figure 2 yes Figure 1 The cross-sectional view of II-II. Figure 1 and Figure 2 As shown, the air conditioner 100 according to the present disclosure includes a housing 10 and an electrical box 20. Next, the respective configurations will be described.

[0012] The housing 10 includes a front cover 11 , a right cover 12 , a left cover 13 , an upper cover 14 , a lower cover 15 , and a rear cover 16 .

[0013] The front cover 11 is a member that covers the front surface of the air conditioner 100. Figure 2 The cross section of the air conditioner shown in the side view is U-shaped or L-shaped. In addition, the front cover 11 is rotated in the +Y+Z direction with the rotating part 11a as the axis to become an open state, and the front side (+Y side) of the electrical box 20 is opened. In this way, it can be easily accessed through the electrical box 20, and replacement can be smoothly performed, etc., and the maintainability is excellent.

[0014] The rotating portion 11a is provided on an arm extending from the left and right (+XX) ends of the housing 10 and the upper end (+Z) toward the housing 10. Moreover, the front surface cover 11 rotates around the rotating portion 11a as an axis to be in an open state and a closed state. In addition, the rotating portion 11a is provided at a height higher (+Z) than a height h25 between a height of the bottom surface 23 of the electrical box 20 and a height of the top surface 24 of the electrical box 20, and is preferably provided at a height h24 which is the same as a height h24 of the top surface 24 of the electrical box 20 or a height higher than the top surface 24. In this way, it can be easily accessed through the electrical box 20, and can be smoothly replaced, etc., with excellent maintainability.

[0015] The right cover 12 and the left cover 13 are components that cover the left and right surfaces of the air conditioner 100 , respectively. The upper cover 14 and the lower cover 15 are components that cover the upper and lower surfaces, respectively. The rear cover 16 is a component that covers the rear surface of the air conditioner 100 .

[0016] The electrical equipment box 20 includes a control unit. The control unit is an example of an "electrical equipment component" that controls the operation of the air conditioner.

[0017] The control unit includes a processor such as a CPU (Central Processing Unit) and controls the air-sending fan, the driving unit of the wind-directing plate, the filter cleaning device, and the like included in the air conditioner 100 .

[0018] The air conditioner has a communication unit inside. The communication unit communicates wirelessly with the operating 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 in accordance with a prescribed communication protocol, or communication that complies with a WiFi communication standard. The prescribed communication protocol is, for example, a TCP / IP (Transmission Control Protocol / Internet Protocol) protocol suite (i.e., Internet Protocol Suite).

[0019] In addition, the communication unit may also include a wireless communication module for performing wireless communication. For example, the communication unit is a wireless communication module for performing short-range wireless communication. Short-range wireless communication is wireless communication with a communication distance of several meters to several tens of meters. Short-range wireless communication is, for example, communication that complies with the communication standards of infrared communication, Bluetooth (registered trademark) or ZigBee (registered trademark). Communication that complies with the communication standard based on Bluetooth (registered trademark) is, for example, BLE (Bluetooth (registered trademark) Low Energy).

[0020] like Figure 2 As shown, the electrical box 20 is accommodated in front of the housing 10. Figure 1 and Figure 2 As shown, in the air conditioner 100 involved in the present disclosure, the electrical box 20 is not provided on the side of the housing 10, but is provided in the width direction of the housing 10 in the front. In other words, the electrical box 20 is provided to cross the left cover 13 from the right cover 12. By providing the electrical box 20 in the width direction of the housing 10 on the front surface of the housing 10, the heat exchanger can be enlarged in the width direction of the housing 10, so that a larger amount of heat can be exchanged.

[0021] like Figure 2 As shown, the electrical box 20 has a base 22 and an electrical cover 21 that can be attached and detached relative to the base 22. The base 22 accommodates a substrate 25 on which the above-mentioned electrical components are mounted. The base 22 is fixed to the filter guide 40 by a fixing portion 30 described later. In addition, the electrical box 20 is arranged on the back side of the front surface cover 11 provided in the housing 10. In addition, a plurality of fixing portions are provided on the left and right.

[0022] Figure 1 as well as Figure 2 The front cover 11 of the air conditioner 100 is shown in an open state. The front cover 11 can be opened and closed relative to the casing 10 by moving the front end 11b of the front cover 11 in the +Y+Z direction and the -YZ direction with the rotating portion 11a as a fulcrum.

[0023] Furthermore, when the front cover 11 is opened, the electrical box 20 is arranged so that the entire front surface of the electrical cover 21 can be visually confirmed. Maintenance is usually carried out from the +YZ direction ( Figure 2 Therefore, it can be visually recognized that it can be operated from the +YZ direction ( Figure 2 The lower right) visual recognition situation, can be Figure 2 The electric component box 20 is shown in a state where the bottom surface 23 is greater than or equal to a height h23 and the top surface 24 of the electric component box 20 is less than or equal to a height h24 .

[0024] Thus, even if the front cover 21 is not completely removed, the electrical box 20 can be easily approached, and the maintainability is excellent. In addition, the lower part of the electrical box 20 is easy to visually confirm, so it is easy to maintain. In addition, the electrical box 20 is provided in the width direction of the housing 10 on the front surface of the housing 10, and the fixing part described later is provided on the electrical box 20, so the electrical box 20 can strengthen the housing, and the rigidity of the air conditioner is improved.

[0025] When the front cover 11 is in a closed state, the electrical component box 20 is disposed directly behind the front cover 11 , and when the front cover 11 is in an open state, the electrical component box 20 can be visually confirmed.

[0026] The open state of the front cover 11 is a state in which the front cover 11 is opened. Figure 2 As shown, the state where the front end 11b of the front surface cover 11 is located above the height h23 of the bottom surface 23 of the electrical box 20 (in the +Z direction), or the state where the front end 11b of the front surface cover 11 is located above the height h24 of the top surface 24 of the electrical box 20 (in the +Z direction) also becomes the open state. Alternatively, the state where the front end 11b of the front surface cover 11 is located above the height h25 between the height of the bottom surface of the electrical box and the height of the top surface of the electrical box (in the +Z direction) also becomes the open state. In the open state, it is preferred that the front end 11b of the front surface cover 11 is located above the height h23 of the bottom surface 23 of the electrical box 20 (in the +Z direction), and it is also preferred that the front end 11b of the front surface cover 11 is located above the height h25 of the bottom surface of the electrical box and the height of the top surface of the electrical box (in the +Z direction), and it is more preferred that the front end 11b of the front surface cover 11 is located above the height h24 of the top surface 24 of the electrical box 20 (in the +Z direction). In this way, the electrical box 20 can be accessed more easily, and the maintainability is excellent. In addition, the distance between the front end 11b of the front cover 11 in the opened state and the lower end of the electrical box 20 is greater than the distance from the height h23 to the height h24 of the bottom surface 23 of the electrical box 20.

[0027] When the front cover 11 is opened, the electrical box 20 is configured so that when the electrical cover 21 is removed, the substrate 25 accommodated in the base 22 can be visually confirmed. In this way, the substrate 25 can be easily accessed during maintenance, and the substrate 25 can be smoothly replaced. In addition, the base 22 of the electrical box 20 can also be parallel to the back cover 16, or the surface of the base 22 can also face Figure 2 The substrate 25 is smaller than the electrical component cover 21. The substrate 25 is arranged in a region overlapping with the front cover 21 when viewed from the front.

[0028] Figure 3 This is a front view of the electric component box 20 mounted on the filter guide 40 . Figure 4 This is a front view after the electric component box 20 is mounted on the filter guide 40, and then the right cover 12 and the left cover 13 are mounted. Figure 5 1 is an exploded perspective view of the filter guide 40, the base 22 of the electrical box 20, the right cover 12, and the left cover 13. Figure 5 The electrical box 20 in FIG. 1 shows only the base 22 .

[0029] like Figure 3 , Figure 4 as well as Figure 5As shown, the electrical box 20 further includes a fixing portion 30, and is fixed to the filter guide 40 through the fixing portion 30. In addition, the filter guide 40 is fixed to the housing 10. The electrical box 20 is fixed to the housing 10 via the filter guide 40. In addition, the fixing portion 30 is provided on the base 22.

[0030] The right side cover 12 has a right side cover front surface 12a extending in the -X direction, and the left side cover 13 has a left side cover front surface 13a extending in the +X direction. Moreover, when the right side cover 12 and the left side cover 13 are mounted on the filter guide 40, the right side cover front surface 12a and the left side cover front surface 13a cover the fixing portion 30. In addition, the electrical cover 21 is not covered by the right side cover front surface 12a and the left side cover front surface 13a. That is, the fixing portion 30 is arranged outside the area that can be visually confirmed under front observation when the front surface cover 11 is opened. In this way, it is possible to perform maintenance by disassembling only the electrical cover 21 without disassembling the right side cover 12, the left side cover 13, and the electrical box 20 itself, and the maintainability is excellent. In addition, the storage area for placing the substrate 25 can be expanded.

[0031] Figure 6 This is an enlarged cross-sectional view of the electrical box, showing the closed state. Figure 7 It is an enlarged cross-sectional view of the electrical component box 20, showing an opened state.

[0032] One of the base 22 and the electrical component cover 21 has a protrusion 21 a , and the other has an opening 22 b into which the protrusion 21 a can be inserted. Figure 6 as well as Figure 7 This is a configuration in which the base 22 has an opening, and the electrical component cover 21 has a protrusion 21 a.

[0033] A plurality of protrusions 21 a and openings 22 b are provided.

[0034] When the electrical component cover 21 is opened or closed, the electrical component cover 21 is rotatably opened or closed within a limited range of a rotation angle θ using the protrusion 21a and the opening 22b as fulcrums. The rotation angle θ of the electrical component cover 21 is limited by the protrusion 21a and the opening 22b.

[0035] The rotation angle θ is an angle at which the electrical component cover 21 does not interfere with the front cover 11 when the electrical component cover 21 is removed, and is an angle greater than 1° and less than 90°.

[0036] It is preferable that the protrusion 21a and the opening 22b are provided at the lower portion of the electrical component box 20. In this way, the electrical component cover 21 can be prevented from falling down in a temporary fixed state described later.

[0037] The range of the limited rotation angle θ is from the closed position of the electrical cover 21 to the temporarily fixed position. The closed position of the electrical cover 21 is a position where the electrical cover 21 covers the base 22 and is opposite to the electrical cover 21. The temporarily fixed position is a position where the electrical cover 21 interferes with the base 22 and stops rotating when the electrical cover 21 is rotated with the protrusion 21a and the opening 22b as a fulcrum from the closed position of the electrical cover 21. In the temporarily fixed position, the protrusion 21a can be removed from the opening 22b by sliding. Figure 6 Move in the direction of the curved arrow shown Figure 7 In the illustrated electrical component box 20 , the electrical component cover 21 is removable.

[0038] The electrical box 20 includes a recessed portion 21c or a raised portion 21d that can be slid on the protrusion 21a and removed. The recessed portion 21c or the raised portion 21d is key-shaped.

[0039] As described above, the air conditioner 100 according to the present disclosure can easily access the electrical box 20 when the front cover 11 is opened, and has excellent maintainability.

[0040] In addition, as described above, each embodiment and each example of the present invention have been described in detail, but it is easy for a person skilled in the art to understand that various modifications can be made without substantially departing from the novel matters and effects of the present invention. Therefore, all such modifications are included in the scope of the present disclosure.

[0041] For example, in the specification or drawings, a term that is recorded at least once together with a different term with a broader or synonymous meaning can be replaced with the different term anywhere in the specification or drawings. In addition, the structure and operation of the air conditioner are not limited to the contents described in the various embodiments and examples of the present disclosure, and various modifications can be implemented.
