In the illustrated example, the first cylinder portion 78 is inserted into the inside of the second cylinder portion 551. This allows the blower unit 2 to rotate relative to the air conditioning unit 1 around the central axis of the first cylinder portion 78 and the second cylinder portion 551 extending in the z direction.

[0073] In this embodiment, a wiring 85 is inserted through the first cylindrical portion 78 and the second cylindrical portion 551. The wiring 85 electrically connects the air conditioning unit 1 and the blower unit 2. For example, the wiring 85 is connected to a power supply section 83 arranged in the air conditioning unit 1. The wiring 85 is also connected to the second blower motor 62 of the second blower section 6 of the blower unit 2, the electric motor of the rotation drive section 77, and the like. Furthermore, the wiring 85 may be connected to the control section 81.

[0074] The protective portion 552 is interposed between the end of the first cylindrical portion 78 on the z1 side in the z direction and the wiring 85. That is, the protective portion 552 is located between the end of the first cylindrical portion 78 on the z1 side in the z direction and the wiring 85 in the z direction. The protective portion 552 overlaps with the first cylindrical portion 78 when viewed from the z1 side in the z direction. The shape of the protective portion 552 is not limited in any way, and may be, for example, a circular ring shape when viewed in the z direction. However, the protective portion 552 is not limited to a circular plate-shaped portion, and may be a frame portion having a circular ring shape. In this embodiment, the protective portion 552 is integral with the second cylindrical portion 551, but is not limited to this and may be a separate body.

[0075] The control unit 81 controls the operation of each part of the air conditioning device A1. There are no limitations on the specific configuration of the control unit 81, and it may have a CPU, for example, and may also include a memory and the like as appropriate.

[0076] The power supply unit 83 converts, for example, commercial 100V AC power into power suitable for operation of each part of the air conditioner A1, and includes an AC / DC converter, a transformer, and the like as appropriate.

[0077] In this embodiment, the blower unit 2 can be rotated on both sides as shown in FIG. 5(b) with the initial position shown in FIG. 5(a) in between. The initial position in FIG. 5(a) is the position of the air conditioning device A1 at the time of shipment or in a non-operating state. The initial position does not include the position of the second blower section 6 around the x direction. In this initial state, the third blower outlet 76 is located on the rear side in the y direction relative to the second blower outlet 64. The air blown out from the third blower outlet 76 can proceed to the z2 side in the z direction. In addition, FIG. 1 and FIG. 2 show a state in which the blower unit 2 is in the initial position, as in FIG. 5(a). In this state, the first housing 5 of the air conditioning unit 1 and the second housing 7 of the blower unit 2 have a shape that has continuity. That is, in this embodiment, the first housing 5 and the second housing 7 are both rectangular when viewed in the z direction, and have shapes and sizes that are approximately the same as each other when the blower unit 2 is in the initial position.

[0078] When the air conditioning device A1 is in operation, the control unit 81 drives and controls the rotation drive unit 77 in response to an operation input from the operation unit 82. As a result, the blower unit 2 rotates around the z direction relative to the air conditioning unit 1 at angles of, for example, 30°, 60°, 90°, etc. in both directions.

[0079] When the air conditioning device A1 is operating and the blower unit 2 is rotating, if an operation is performed to stop the operation of the air conditioning device A1, the control unit 81 controls the blower unit 2 to move to the initial position shown in Figure 5 (a).

[0080] The sensor and the like used for the control to move the blower unit 2 to the initial position are not limited in any way. In this embodiment, for example, a contact portion is provided at a position where the blower unit 2 is rotated 45° to one side relative to the air conditioning unit 1, where a predetermined portion of the blower unit 2 contacts. The contact with this contact portion prevents the electric motor of the rotation drive unit 77 from rotating. By using a stepping motor as the electric motor, for example, the blower unit 2 can be moved to the initial position by rotating it 45° in the opposite direction from the contact position. Note that the rotation speed at which the blower unit 2 is moved to the initial position when the operation is stopped is preferably set to a speed faster than the rotation speed during normal operation. This can shorten the user's waiting time.

[0081] A wide variety of control methods can be adopted for the operation control of the air conditioning unit 1 and the blower unit 2 of the air conditioner A1. FIG. 15 shows an example of the operation control of the air conditioner A1. When the control unit 81 starts the control of the blower unit 2, it judges whether the first blower unit 4 of the air conditioning unit 1 is in operation ON (step S1). If the operation of the first blower unit 4 is ON (step S1: Yes), the control unit 81 controls the blower unit 2 to operate in accordance with the operation of the first blower unit 4. That is, the control unit 81 controls the blower unit 2 to operate in accordance with the operation of the air conditioning unit 1. On the other hand, if the operation of the first blower unit 4 is OFF (step S1: No), the control unit 81 maintains the state in which the blower unit 2 is stopped. Note that, if step S1: Yes, the blower unit 2 may be operated simultaneously with the start of the operation of the first blower unit 4, or may be operated after a predetermined timer time.

[0082] That is, when the first blower 4 is in silent mode (step S2: silent), the control unit 81 sets the blower unit 2 to a low-speed mode and controls its operation (step S3). The operation control of the blower unit 2 includes, for example, the operation control of the second blower motor 62 of the second blower 6. When the first blower 4 is in standard mode (step S2: standard), the control unit 81 sets the blower unit 2 to a medium-speed mode and controls its operation (step S4). When the first blower 4 is in turbo mode (step S2: turbo), the control unit 81 sets the blower unit 2 to a high-speed mode and controls its operation (step S5). Note that in steps S3 to S5, the operation of the blower unit 2 may be changed simultaneously with the switching of the operation mode of the first blower 4, or the operation may be changed after a predetermined timer time has elapsed.

[0083] In addition, in the initial state when the air conditioning device A1 is powered on and starts operating, for example, the first blower section 4 is set to standard mode, and the blower unit 2 is set to medium speed mode. The control unit 81 may also have an automatic mode that automatically switches the operation mode of the first blower section 4 according to the state of the air outside the machine. In this automatic mode, depending on the state of the air outside the machine, the operation mode is appropriately switched between a first state in which the first blower section 4 is operated in silent mode and the second blower section 6 is operated in low speed mode, and a second state in which the first blower section 4 is operated in standard mode and the second blower section 6 is operated in medium speed mode. In this case, the third state in which the first blower section 4 is operated in turbo mode and the second blower section 6 is operated in high speed mode can be manually switched by the user's operation input to the operation unit 82.

[0084] The air volume was measured in accordance with the provisions of JIS A 1431 when only the first blower 4 was operated and when both the first blower 4 and the second blower 6 were operated. When only the first blower 4 was operated, the air volume when the first blower 4 was in silent mode was 2.1 m 3 / min, air volume in standard mode is 2.8m 3 / min, the air volume in turbo mode is 5.3m 3When the first blower 4 and the second blower 6 were operated, the air volume was 2.5 m 3 / min, and the air volume when the first blower 4 is in standard mode and the second blower 6 is in medium speed mode is 3.3 m 3 / min, and the air volume when the first blower 4 is in turbo mode and the second blower 6 is in high speed mode is 6.5 m 3 / min. From this result, it can be seen that in each operation mode, when the first blower section 4 and the second blower section 6 are operated, the air volume is increased compared to when only the first blower section 4 is operated.

[0085] Therefore, the dust collection speed, dust collection amount, and deodorization speed were compared between operating only the first blower section 4 and operating both the first blower section 4 and the second blower section 6. As a result, when operating the first blower section 4 and the second blower section 6, the dust collection speed, dust collection amount, and deodorization speed were improved compared to operating only the fan of the first blower section 4. From this result, it can be said that the provision of the second blower section 6 increased the air volume, and improved the dust collection speed, dust collection amount, and deodorization speed.

[0086] Next, the operation of the air conditioner A1 will be described.

[0087] According to this embodiment, as shown in FIG. 6, a path is provided in which air is blown out from the second air outlet 64 via the first air outlet 56 and the second air blowing section 6, and a path is provided in which air is blown out from the third air outlet 76 without passing through the second air blowing section 6 from the first air outlet 56. This allows the conditioned air to be sent out of the machine more smoothly even if there is a difference in the air volume between the first air blowing section 4 and the second air blowing section 6. For example, when the air volume of the first air blowing section 4 is greater than the air volume of the second air blowing section 6, the air corresponding to the difference between the two is blown out from the third air outlet 76. In addition, even when the second air blowing section 6 is not operating, the air from the first air outlet 56 can be blown out from the third air outlet 76. Furthermore, when the air volume of the second air blowing section 6 is greater than the air volume of the first air blowing section 4, the air volume can be adjusted by sucking air into the second air intake 63 from, for example, the third air outlet 76 or an opening provided in the rear section 74 or the front section 75.

[0088] 1, 2, and 5, the third air outlet 76 is provided in a position that is visible when viewed in the z direction. This makes it possible to blow air out more efficiently than when the third air outlet 76 is provided on the side, for example, and can promote airflow to the entire room in which the air conditioning device A1 is installed.

[0089] In the air conditioner disclosed in Patent Document 1, a mechanical part corresponding to a blower unit 2 rotates relative to a mechanical part corresponding to an air conditioning unit 1. In the air conditioner of this document, it is assumed that wiring is provided to electrically connect these mechanical parts. This wiring may come into contact with or rub against surrounding parts when it rotates. In this case, there is a concern that the wiring may break or an unintended short circuit may occur.

[0090] In this embodiment, one of the objectives is to provide an air conditioning device capable of suppressing the shortening of the life span of the wiring. According to this embodiment, as shown in FIG. 7, a protective part 552 is interposed between the wiring 85 inserted into the second tube part 551 and the first tube part 78 and the end part on the z1 side in the z direction of the first tube part 78. The protective part 552 is fixed without rotating even when the blower unit 2 rotates. Therefore, when the wiring 85 is twisted or moved by the rotation of the blower unit 2, it is possible to prevent the wiring 85 from contacting or rubbing against the end part on the z1 side in the z direction of the first tube part 78. Therefore, it is possible to reduce the occurrence of breakage or unintended short circuit of the wiring 85 and suppress the shortening of the life span of the wiring 85.

[0091] For example, in the air conditioning apparatus disclosed in JP 2019-25431 A, the first filter and the second filter are assembled separately. For this reason, during maintenance, the first filter and the second filter must be removed and installed separately, which is a problem in that the work is complicated.

[0092] In this embodiment, one of the objectives is to provide an air conditioner that is easier to use by more efficiently attaching and detaching a plurality of filters. According to this embodiment, as shown in Fig. 3 and Figs. 9 to 13, in the air purifying unit 31, the dust collecting filter 315 and the deodorizing filter 316 are housed in one filter case 311. As a result, by attaching and detaching the air purifying unit 31 to and from the second housing 7, it is possible to complete the attachment and detachment of the plurality of filters, namely the dust collecting filter 315 and the deodorizing filter 316. Therefore, it is possible to improve the work efficiency.

[0093] 3, the air purifying unit 31 can be inserted and removed in the x direction through the opening 57 of the first housing 5. This allows the user to insert and remove the air purifying unit 31 in the horizontal direction, improving operability.

[0094] The air conditioner disclosed in Patent Document 1 does not specifically disclose how to control the mechanical parts corresponding to the air conditioning unit 1 and the mechanical parts corresponding to the blower unit 2 in correspondence with each other. For this reason, cases are expected in which the operations of both are not properly coordinated.

[0095] In this embodiment, one of the objectives is to make the air blowing unit 2 function more effectively by linking the control between the air conditioning unit 1 and the blowing unit 2. In this embodiment, as described with reference to Figs. 14 and 15, the control unit 81 controls the air blowing unit 2 to operate according to the operation of the first blowing unit 4 included in the air conditioning unit 1. This allows the air blowing unit 2 to operate automatically when the first blowing unit 4 is operating, and prevents the air blowing unit 2 from operating unnecessarily when the first blowing unit 4 is not operating. In addition, by switching the operating state (low speed mode, medium speed mode, high speed mode, etc.) of the blowing unit 2 according to the operating state (silent mode, standard mode, turbo mode, etc.) of the first blowing unit 4, the air blowing unit 2 and the air conditioning unit 1 can be operated in a more coordinated manner, and the noise from the first blowing unit 4 and the second blowing unit 6 can be suppressed while maintaining the air purification performance in each operating mode of the first blowing unit 4. Furthermore, since the user does not need to manually switch the operating state of the blower unit 2, it is possible to avoid a situation in which the operation of the blower unit 2 is not started and only the first blower section 4 is operating.

[0096] As described with reference to Figs. 5(a) and (b), the control unit 81 controls the blower unit 2 to move to the initial position when operation is stopped. As a result, the blower unit 2 is always placed in the initial position when operation is stopped. This makes it possible to prevent the appearance of the air conditioning device A1 when stopped from becoming complicated. In particular, as shown in Figs. 1, 2, and 5(a), when the blower unit 2 is in the initial position, the first housing 5 of the air conditioning unit 1 and the second housing 7 of the blower unit 2 have a shape that has continuity. This makes it possible to further improve the aesthetic appearance of the air conditioning device A1 when stopped.
