[0060] As shown in Figure 1 , Figure 1 The external structure of the air conditioner 100 in the embodiment is shown. The air conditioner 100 can be an integrated air conditioner 100. As shown in Figure 2 , 3 The air conditioner 100 includes a cabinet 2 and a fan assembly 1. One side of the cabinet 2 is the indoor side, and the other side of the cabinet 2 is the outdoor side. The fan assembly 1 is arranged in the cabinet 2, and is located on the indoor side.

[0061] The box 2 comprises a base plate 21. The base plate 21 is generally horizontally arranged. The fan assembly 1 is fixed on the base plate 21.

[0062] The fan assembly 1 comprises a first housing 11, a second housing 12, a fan wheel 13 and a driving motor 14. The first housing 11 is configured as a generally rectangular plate. The thickness of the first housing 11 is greater than the width of the fan wheel 13 in the axial direction. One end of the first housing 11 abuts against the base plate 21. The first housing 11 is perpendicular to the base plate 21. The first housing 11 and the base plate 21 can be connected by bolts, screws or welding. The first housing 11 is provided with a first mounting groove 111 and a plurality of air outlet grooves 112. The first mounting groove 111 and the plurality of air outlet grooves 112 are arranged on the same side of the first housing 11. The first housing 11 is provided with a planar plate surface, and the first mounting groove 111 and the plurality of air outlet grooves 112 can be recessed from the plate surface. The first mounting groove 111 is configured as a circular groove, and the side surface of the first mounting groove 111 is a cylindrical surface. There are at least two air outlet grooves 112. The air outlet grooves 112 are arranged around the first mounting groove 111, and adjacent two air outlet grooves 112 are arranged at intervals. The plurality of air outlet grooves 112 are directly connected with the first mounting groove 111. The air outlet groove 112 has an outlet 113, which is the opening of the air outlet groove 112. The first housing 11 is further provided with a first through hole. The first through hole is coaxially arranged with the first mounting groove 111.

[0063] The second housing 12 comprises a plate body 121 and a surrounding plate 124. The plate body 121 is configured as a flat plate. The plate body 121 is provided with a first air inlet hole 122. The first air inlet hole 122 can be a circular hole. The first air inlet hole 122 vertically penetrates the plate body 121. The surrounding plate 124 is arranged on one side of the plate body 121. The surrounding plate 124 is a circular arc plate. The surrounding plate 124 is enclosed around the first air inlet hole 122 and extends along the circumferential direction of the first air inlet hole 122. The air supply gap 125 is formed between the two ends of the surrounding plate 124. From one end of the surrounding plate 124 to the other end of the surrounding plate 124, the radial distance between the inner circumferential surface of the surrounding plate 124 and the first air inlet hole 122 gradually increases. The outer circumferential surface of the surrounding plate 124 is a cylindrical surface, which is coaxially arranged with the first air inlet hole 122. The surrounding plate 124 extends into the first mounting groove 111 from the plate body 121, and the outer circumferential surface of the surrounding plate 124 and the side surface of the first mounting groove 111 form a clearance fit. The surrounding plate 124 can rotate around the axis of the first mounting groove 111 in the first mounting groove 111, so that the first housing 11 and the second housing 12 are rotationally connected. When the second housing 12 is rotated, the air supply gap 125 on the second housing 12 is also rotated, and the air supply gap 125 can be rotated to a position connected with any air outlet groove 112.

[0064] As Figure 2As shown, the driving motor 14 comprises a first body 141 and a first main shaft 142. The first body 141 is fixed relative to the first shell 11. The first body 141 can be arranged on the side of the first shell 11 away from the second shell 12. The first main shaft 142 is arranged through the first body 141. The first main shaft 142 is coaxially arranged with the first mounting slot 111. One end of the first main shaft 142 extends into the first mounting slot 111 through the first through hole, thereby driving the wind wheel 13 located in the first mounting slot 111 to rotate. A sealing member can be arranged between the outer circumferential surface of the first main shaft 142 and the inner circumferential surface of the first through hole to seal the gap between the first main shaft 142 and the first through hole, thereby achieving dynamic sealing.

[0065] As shown in Figure 4 , 5 The wind wheel 13 can be a centrifugal impeller, for example, a multi-blade impeller. The wind wheel 13 is arranged in the shroud 124. The wind wheel 13 is sleeved on the first main shaft 142 of the driving motor 14, and the wind wheel 13 is coaxial with the first main shaft 142 of the driving motor 14. The driving motor 14 can drive the wind wheel 13 to rotate around its own axis. In the rotation direction of the wind wheel 13, the radial distance between the inner circumferential surface of the shroud 124 and the wind wheel 13 gradually increases from the air supply gap 125 of the shroud 124.

[0066] The first shell 11 and the second shell 12 form a volute structure. When the driving motor 14 drives the wind wheel 13 to rotate, the wind wheel 13 drives the air to rotate. In the process of rotation, the air is subjected to the action of centrifugal force and moves in the radial direction outward from the wind wheel 13. The middle region of the wind wheel 13 forms a negative pressure. The air is sucked into the shroud 124 from the first air inlet hole 122 of the plate body 121, and the air sucked into the shroud 124 is pressurized and output from the air supply gap 125.

[0067] In actual work, the indoor air enters the first installation groove 111 through the first air inlet hole 122 on the plate body 121, and enters an air outlet groove 112 through the air supply gap 125 of the surrounding plate 124 under the centrifugal action of the fan wheel 13, so that the air outlet 113 of the air outlet groove 112 can blow air. At this time, the air outlets 113 of the other air outlet grooves 112 except the first air outlet groove 112 are blocked and closed by the circumferential surface of the surrounding plate 124, and these air outlets 113 cannot blow air. When it is necessary to switch the air outlet position of the air conditioner 100, the second shell 12 is rotated to make the second air outlet groove 112 abut and cooperate with the air supply gap 125, that is, the indoor air enters the first installation groove 111 through the first air inlet hole 122 on the plate body 121, and enters the second air outlet groove 112 through the air supply gap 125 of the surrounding plate 124 under the centrifugal action of the fan wheel 13, so that the air outlet 113 of the air outlet groove 112 can blow air. At this time, the air outlets 113 of the other air outlet grooves 112 except the second air outlet groove 112 are blocked and closed by the circumferential surface of the surrounding plate 124, and these air outlets 113 cannot blow air. Of course, when the number of air outlet grooves 112 is more, the air supply gap 125 can also be abutted and cooperated with other air outlet grooves 112 according to needs.

[0068] The fan assembly 1 provided by the embodiment gradually increases the distance between the surrounding plate 124 and the fan wheel 13 from the air supply gap 125 in the rotation direction of the fan wheel 13, and the first shell 11 and the second shell 12 enclose a volute structure. The air entering the volute structure is pressurized, and the pressurized air can enter the indoor environment more quickly for temperature regulation. The fan assembly 1 can adjust the air outlet position according to needs: rotating the second shell 12 to make the air supply gap 125 on the surrounding plate 124 of the second shell 12 communicate with one of the plurality of air outlet grooves 112 on the first shell 11, and the air outlet 113 of the air outlet groove 112 connected with the air supply gap 125 blows air. Therefore, rotating the second shell 12 can switch the air outlet 113, and further switch the air outlet channel connected with the air outlet 113. The air outlet 23 corresponding to the plurality of air outlet grooves 112 is arranged on the cabinet 2, and the air outlet grooves 112 are connected with the air outlet 23 through pipelines or channels, so that side air outlet or upper air outlet and other various position air outlets on the cabinet 2 can be realized, the selection range of the user and the application scenarios of the air conditioner 100 are improved, and the use experience of the user is improved.

[0069] In an exemplary embodiment, as Figure 3As shown, a bracket 127 is provided on the second housing 12. The bracket 127 is disposed within the first air inlet 122. The bracket 127 can be constructed as a spoke-shaped structure. The fan assembly 1 also includes a switching motor 15. The switching motor 15 includes a second body 151 and a second main shaft, the second main shaft extending from the second body 151. The second main shaft of the switching motor 15 is fixedly connected to the bracket 127. The second main shaft of the switching motor 15 is coaxially arranged with the first air outlet 123. The second body 151 of the switching motor 15 is fixed relative to the first housing 11. The switching motor 15 is used to drive the second housing 12 to rotate around the axis of the first mounting groove 111. The switching fan can be a stepper motor.

[0070] The switching motor 15 drives the second housing 12 to rotate around the axis of the first mounting groove 111, allowing the air supply notch 125 of the second housing 12 to switch the connected air outlet slot 112, thus changing the air outlet position of the fan assembly 1. The switching motor 15 enables automated switching of the air outlet position. Users can control the switching motor 15 via remote control or other means, thereby controlling the rotation of the second housing 12 to switch to the appropriate air outlet channel. The operation is simple and convenient, highly automated, and provides a good user experience. In practical applications, the fan assembly 1 may also include corresponding position switches. When the switching motor 15 drives the second housing 12 to rotate to the correct position, the corresponding position switch is triggered, ensuring precise alignment between the air supply notch 125 and the air outlet slot 112.

[0071] It should be understood that, in addition to the automatic method of "switching motor 15" as described above, the switching motor 15 may not be set up, that is, the air outlet channel may be switched manually: the user manually rotates the second housing 12 so that the air supply notch 125 of the second housing 12 aligns with the corresponding air outlet slot 112 on the first housing 11 to adjust the air outlet position of the fan assembly 1.

[0072] In one exemplary embodiment, such as Figure 3 , 4 As shown, the plate 121 covers all the air outlet slots 112, and the plate 121 is also provided with a first air outlet hole 123 penetrating the plate 121. The air supply notch 125 and the first air outlet hole 123 on the second housing 12 can rotate with the second housing 12 to connect to the same air outlet slot 112.

[0073] The plate body 121 covers the air outlet groove 112. When the air supply gap 125 and the first air outlet hole 123 are communicated with the same air outlet groove 112, air can only be discharged through the first air outlet hole 123 of the air blower assembly 1, avoiding air leakage from the air outlet groove 112 which is not communicated with the first air outlet hole 123. The air outlet groove 112 communicates the air supply gap 125 and the first air outlet hole 123, that is, air is pressurized and delivered to the air outlet groove 112 through the air supply gap 125, and then discharged through the first air outlet hole 123. The second shell 12 rotates relative to the first shell 11, that is, the surrounding plate 124 provided with the air supply gap 125 and the plate body 121 provided with the first air outlet hole 123 can rotate together, and the first shell 11 provided with a plurality of air outlet grooves 112 remains stationary. When the second shell 12 is rotated, the position of the first air outlet hole 123 changes, and thus the air outlet position of the air blower assembly changes. When the second shell 12 is rotated to a set position, the air supply gap 125 and the first air outlet hole 123 can be communicated with the air outlet groove 112 at the set position, thereby ensuring unobstructed air flow.

[0074] The number of first air outlet holes 123 can be one, and the first air outlet hole 123 can be arranged on the plate body 121 outside the air supply gap 125. When the second shell 12 rotates relative to the first shell 11, the air supply gap 125 and the first air outlet hole 123 are both communicated with the same air outlet groove 112, and the first air outlet hole 123 can subsequently guide air out of the room through a channel or a pipeline.

[0075] In an exemplary embodiment, as shown in Figures 6-8 The fan assembly 1 further includes a support 16. The support 16 is arranged on the side of the second shell 12 away from the first shell 11. The support 16 is fixed to the bottom plate 21 of the cabinet 2. The support 16 is rotationally connected with the second shell 12.

[0076] The second shell 12 is arranged between the first shell 11 and the support 16. The first shell 11 and the support 16 remain stationary, and the second shell 12 can rotate relative to the first shell 11 and the support 16. The first shell 11 and the support 16 support the second shell 12 from opposite sides of the second shell 12, so that the second shell 12 is installed more stably.

[0077] In an exemplary embodiment, the support 16 is provided with a second air inlet hole 161. The second air inlet hole 161 is a through hole with a circular cross section. The second air inlet hole 161 is coaxially arranged with the first air inlet hole 122.

[0078] The second shell 12 further comprises a cylinder 126. The cylinder 126 is arranged on the side of the plate body 121 which is away from the first shell 11. The cylinder 126 is arranged around the first air inlet hole 122, and the cylinder 126 is coaxially arranged with the first air inlet hole 122. The cylinder 126 is further inserted into the second air inlet hole 161. The outer circumferential surface of the cylinder 126 is in clearance fit with the inner circumferential surface of the second air inlet hole 161. The cylinder 126 is rotatable in the second air inlet hole 161.

[0079] The cylinder 126 of the second shell 12 cooperates with the second air inlet hole 161 of the support 16 to form a rotational connection between the second shell 12 and the support 16. Air can enter the first air inlet hole 122 from the second air inlet hole 161, and then enter the baffle 124 from the first air inlet hole 122.

[0080] In an exemplary embodiment, the second air inlet hole 161 is a threaded hole, and is provided with an internal thread. The outer circumferential wall of the cylinder 126 of the second shell 12 is provided with an external thread. The external thread and the internal thread are screwed together.

[0081] The cylinder 126 is screwed into the second air inlet hole 161. Due to the cooperation between the internal thread on the second air inlet hole 161 and the external thread on the cylinder 126, the sealing between the cylinder 126 and the second air inlet hole 161 is improved, air leakage at the connection between the second shell 12 and the support 16 is avoided, the overall sealing of the air flow channel is improved, and the air pressurization effect of the wind wheel 13 is not affected.

[0082] In an exemplary embodiment, as shown in Figure 6 The support 16 is configured in a substantially plate-like structure. The support 16 is parallel to the plate body 121. The second air inlet hole 161 vertically penetrates the support 16. The support 16 is further provided with a plurality of second air outlet holes 162. The second air outlet holes 162 are through holes, and the second air outlet holes 162 vertically penetrate the support 16. The plurality of second air outlet holes 162 are arranged around the second air inlet hole 161.

[0083] The number of the second air outlet holes 162 is the same as the number of the air outlet grooves 112, and the plurality of second air outlet holes 162 one-to-one correspond to the plurality of air outlet grooves 112. Each second air outlet hole 162 is aligned with the air outlet groove 112 corresponding to the second air outlet hole 162 in the axial direction of the first air inlet hole 122. When the second shell 12 is rotated to the end of the first air inlet hole 123 which is connected to the air outlet groove 112, the other end of the first air inlet hole 123 is also connected to the second air outlet hole 162 corresponding to the air outlet groove 112, and the first air inlet hole 123 connects the air outlet groove 112 and the second air outlet hole 162. Air flow can enter the air outlet groove 112 from the air supply gap 125, and then sequentially pass through the air outlet groove 112, the first air inlet hole 123 and the second air outlet hole 162, and be output from the second air outlet hole 162.

[0084] In one illustrative embodiment, the cabinet 2 comprises a first panel 20. The first panel 20 is a substantially square panel. The length and width of the first panel 20 are equal. The first panel 20 is perpendicular to the chassis 21. One end of the first panel 20 is fixed on one end of the chassis 21. The first panel 20 is disposed on the side of the support 16 facing away from the second housing 12. The first panel 20 is provided with an air inlet 22 and a plurality of air outlets 23. The air inlet 22 and the air outlets 23 all penetrate the first panel 20. The air inlet 22 is aligned with the second air inlet hole 161 of the support 16. The number of the air outlets 23 is the same as the number of the second air outlet holes 162 of the support 16, the air outlets 23 correspond to the second air outlet holes 162 one by one, and the air outlets 23 are connected to the corresponding second air outlet holes 162. One air outlet 23 can be located on one side of the air inlet 22, and the other air outlet 23 can be located above the air inlet 22.

The second body 151 of the switching motor 15 is mounted on the end of the mounting seat 17 close to the first air inlet hole 122. In this way, the second body 151 of the switching motor 15 is fixed.

[0091] In one illustrative embodiment, as shown in Figure 8 The air conditioner 100 further comprises a second heat exchanger 25, a fan 27 and a compressor 26. The second heat exchanger 25 and the compressor 26 are arranged in the cabinet 2 and are fixed on the bottom plate 21 of the cabinet 2. The second heat exchanger 25 and the fan 27 are arranged on the outdoor side of the cabinet 2. The second heat exchanger 25 is used for heat exchange with outdoor air, and the fan 27 is used for blowing air to the second heat exchanger 25 to accelerate the heat exchange between the second heat exchanger 25 and outdoor air. The first heat exchanger 24, the second heat exchanger 25 and the compressor 26 are connected into a loop through pipes, and the loop is filled with refrigerant. The compressor 26 can drive the refrigerant to flow in the loop so that the first heat exchanger 24 and the second heat exchanger 25 perform heat exchange.

[0092] When the air conditioner 100 is in cooling mode, the heat in indoor air is conducted to the first heat exchanger 24, the refrigerant carries the heat on the first heat exchanger 24 to the second heat exchanger 25, and the heat on the second heat exchanger 25 is dissipated to outdoor air; when the air conditioner 100 is in heating mode, the heat in outdoor air is conducted to the second heat exchanger 25, the refrigerant carries the heat on the second heat exchanger 25 to the first heat exchanger 24, and the heat on the first heat exchanger 24 is dissipated to indoor air.
