[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Example

[0024] Please refer to Figure 1 and Figure 2The embodiment of the present invention provides an air duct assembly 100 for blowing air into a room. The air duct assembly 100 can simplify the disassembly and assembly process, reduce the disassembly and assembly parts and steps, improve the disassembly and assembly efficiency, realize quick disassembly and assembly, and facilitate the cleaning of the air duct assembly 100.

[0025] It should be noted that the air duct assembly 100 is applied to a vertical air conditioner, which is placed vertically indoors. An evaporator (not shown) is provided in the vertical air conditioner. The air duct assembly 100 is used to generate airflow, which passes through the evaporator and blows into the room to achieve the function of blowing hot air or cold air into the room, thereby adjusting the indoor temperature.

[0026] The air duct assembly 100 includes a first air duct 110, a second air duct 120, a crossflow blade 130, a drive motor 140 and a sweeping blade 150. One end of the first air duct 110 is detachably connected to the second air duct 120, and the first air duct 110 and the second air duct 120 are combined to form an air outlet cavity 160, and the air outlet cavity 160 is used for air flow to pass through, and the first air duct 110 and the second air duct 120 can guide the air flow to blow out indoors. The other end of the first air duct 110 is used to be hinged with a rear panel (not shown), and the rear panel is arranged in the vertical air conditioner. The first air duct 110 can rotate relative to the rear panel to disengage from the second air duct 120, thereby opening the air outlet cavity 160, so that the inner wall of the first air duct 110 is exposed to the outside, which is convenient for disassembly and assembly of the air duct assembly 100.

[0027] The driving motor 140 and the crossflow blades 130 are both installed on the first air duct 110. The driving motor 140 is connected to the crossflow blades 130. The driving motor 140 can drive the crossflow blades 130 to rotate to drive the air to form an airflow. The crossflow blades 130 are arranged in the air outlet cavity 160. The crossflow blades 130 can suck the outside air into the air outlet cavity 160 to form an airflow. In this process, the airflow will pass through the evaporator to achieve the cooling or heating function of the airflow. The first air duct 110 is provided with an air outlet 111 connected to the air outlet cavity 160. The crossflow blades 130 can also drive the airflow to be blown out from the air outlet 111 into the room to adjust the indoor temperature. The sweeping blades 150 are installed in the air outlet 111. The sweeping blades 150 are used to adjust the air outlet direction.

[0028] It is worth noting that the drive motor 140, the crossflow fan blades 130 and the sweeping blades 150 are all arranged on the first air duct 110. When the first air duct 110 rotates relative to the rear panel, the drive motor 140, the crossflow fan blades 130 and the sweeping blades 150 will also rotate with the first air duct 110. When the first air duct 110 rotates to the extreme position, the inner wall of the first air duct 110 is completely exposed to the outside. At this time, the drive motor 140, the crossflow fan blades 130 and the sweeping blades 150 are also exposed to the outside. The user can clean the drive motor 140, the crossflow fan blades 130 and the sweeping blades 150 without disassembling them, and the cleaning efficiency is high; the user can also easily remove the drive motor 140, the crossflow fan blades 130 and the sweeping blades 150 from the first air duct 110 or install them on the first air duct 110, which is convenient and quick, making the disassembly and assembly process of the air duct assembly 100 simple, with fewer disassembly and assembly parts and steps, and high disassembly and assembly efficiency, which is convenient for cleaning the air duct assembly 100.

[0029] In this embodiment, the axis of rotation of the first air duct 110 relative to the rear panel extends in the vertical direction, that is, the first air duct 110 can rotate relative to the rear panel with the vertical direction as the axis, and detach from the second air duct 120 during the rotation process, and open the air outlet cavity 160, and the axis of the crossflow fan blade 130 is also in the vertical direction, and the axis of the crossflow fan blade 130 is parallel to and spaced from the axis of rotation of the first air duct 110 relative to the rear panel.

[0030] Please refer to Figure 3 and Figure 4 The first air duct 110 includes a first air duct body 112 and a first rotating member 113. One end of the first rotating member 113 is fixedly connected to the first air duct body 112, and the other end is hinged to the rear panel. The first rotating member 113 can rotate relative to the rear panel to drive the first air duct body 112 to rotate relative to the rear panel. At the same time, the first rotating member 113 can also support the first air duct body 112 to prevent the first air duct body 112 from falling off the rear panel. The crossflow blades 130, the drive motor 140 and the sweeping blades 150 are all installed on the first air duct body 112. When the first air duct body 112 rotates outward along with the first rotating part 113, the crossflow blades 130, the drive motor 140 and the sweeping blades 150 also rotate outward accordingly, which is convenient for disassembly and cleaning. When the first air duct body 112 rotates inward along with the first rotating part 113, the crossflow blades 130, the drive motor 140 and the sweeping blades 150 also rotate inward accordingly, which is convenient for installation.

[0031] In this embodiment, the first rotating member 113 and the first air duct body 112 are integrally formed to improve the connection strength. However, this is not limited to this.

The upper bracket 114 and the lower bracket 115 are arranged at the two ends of the connecting frame 116 opposite to each other, and are both fixedly connected to the connecting frame 116. In this embodiment, the upper bracket 114, the connecting frame 116 and the lower bracket 115 are integrally formed to improve the connection strength. The upper bracket 114, the connecting frame 116, the lower bracket 115 and the second air duct 120 are combined to form an air outlet cavity 160. The crossflow fan blade 130 is arranged between the upper bracket 114 and the lower bracket 115, that is, arranged in the air outlet cavity 160. The crossflow fan blade 130 can suck air into the air outlet cavity 160 or blow air out of the air outlet cavity 160. The drive motor 140 is installed on the top of the upper bracket 114 for easy installation and disassembly. The air outlet 111 is provided in the connecting frame 116, and the air blown out by the crossflow blades 130 enters the room through the air outlet 111. The first rotating member 113 is fixedly connected to the connecting frame 116, and the first rotating member 113 can drive the connecting frame 116 to rotate relative to the rear panel, thereby driving the entire first air duct body 112 to rotate relative to the rear panel.

[0033] It should be noted that the air outlet 111 is in an arc shape, that is, the surface of the first air duct body 112 on which the air outlet 111 is provided is an arc surface, and the crossflow blades 130 are arranged on the inner side of the arc surface, so that the air flow can be blown out from the inner side of the arc surface to the outer side. In this embodiment, the first rotating member 113 is in an arc plate shape, and the first rotating member 113 is arranged to extend along the circumference of the air outlet 111, that is, the curvature of the first rotating member 113 is the same as the curvature of the air outlet 111, so as to save space, facilitate the first rotating member 113 to drive the first air duct body 112 to rotate outward or inward, and can improve the flatness of the connection between the first rotating member 113 and the first air duct body 112, thereby improving the connection strength between the first rotating member 113 and the first air duct body 112.

[0034] In this embodiment, a rotation groove 117 is provided at one end of the first rotating member 113 away from the first air duct body 112, and the rotation groove 117 is used to cooperate with a rotating shaft (not shown) provided on the rear panel. The axial direction of the rotating shaft is the same as the axial direction of the rotating groove 117, and both are in the vertical direction. The rotating shaft extends into the rotating groove 117 and can rotate relative to the rotating groove 117. The rotating groove 117 can limit the rotating shaft to prevent the rotating shaft from being separated from the rotating groove 117. However, it is not limited to this. In other embodiments, a rotating shaft is provided at one end of the first rotating member 113 away from the first air duct body 112, and a rotation groove 117 is provided on the rear panel. The rotating shaft extends into the rotating groove 117 and rotates with the rotating groove 117, which can also realize the function of rotating the first air duct body 112 relative to the rear panel.

[0035] It should be noted that there are multiple first rotating members 113, which are arranged in parallel and spaced apart on the first air duct body 112 in the vertical direction, and are all fixedly connected to the first air duct body 112. The first air duct body 112 can be rotated relative to the rear panel by the multiple first rotating members 113 at the same time. The multiple first rotating members 113 can improve the rotation accuracy of the first air duct body 112 to ensure that the first air duct body 112 can rotate in the vertical direction as the axis. The multiple first rotating members 113 can also improve the support strength of the first air duct body 112 to ensure that the first air duct body 112 will not fall off the rear panel. In this embodiment, there are two first rotating members 113, and the two first rotating members 113 are relatively arranged at the two ends of the first air duct body 112, but it is not limited thereto. In other embodiments, the number of the first rotating members 113 can be three or four, and the number of the first rotating members 113 is not specifically limited.

[0036] In this embodiment, one end of the second air duct 120 is detachably connected to the first air duct 110, and the other end is used for hinged connection with the rear panel. The second air duct 120 can rotate relative to the rear panel to further open the air outlet cavity 160, so that the inner wall of the second air duct 120 is exposed to the outside, which is convenient for disassembly and cleaning of the air duct assembly 100. However, it is not limited to this. In other embodiments, one end of the second air duct 120 is detachably connected to the first air duct 110, and the other end is used for fixed connection with the rear panel. In this case, the connection structure between the second air duct 120 and the rear panel is stable and reliable to prevent the second air duct 120 from being displaced relative to the rear panel.

[0037] Specifically, the axis of rotation of the second air duct 120 relative to the rear panel extends in the vertical direction, that is, the second air duct 120 can rotate relative to the rear panel with the vertical direction as the axis, and the axis of rotation of the second air duct 120 relative to the rear panel and the axis of rotation of the first air duct 110 relative to the rear panel are arranged in parallel to facilitate the separation or closing of the first air duct 110 and the second air duct 120.

[0038] The second air duct 120 includes a second air duct body 121 and a second rotating member 122. The second air duct body 121 is detachably connected to the first air duct 110, and the second air duct body 121 and the first air duct body 112 are combined to form an air outlet cavity 160. The second rotating member 122 is fixedly connected to the second air duct body 121, and the second rotating member 122 is used to be hinged to the rear panel.

[0039] In this embodiment, the second rotating member 122 and the second air duct body 121 are integrally formed to improve the connection strength. However, this is not limited to this. In other embodiments, the second rotating member 122 and the second air duct body 121 are separately provided and fixedly connected by screws, which is convenient for production and processing and can save processing costs.

[0040] In this embodiment, the second rotating member 122 is a rotating cylinder, which is fixedly connected to the second air duct body 121, and a rotating shaft (not shown) is provided on the rear panel, the axial direction of the rotating shaft is the same as the axial direction of the rotating cylinder, and both are in the vertical direction, the rotating shaft extends into the rotating cylinder, and can rotate relative to the rotating cylinder, and the rotating cylinder can limit the rotating shaft to prevent the rotating shaft from being separated from the rotating cylinder. However, it is not limited to this, in other embodiments, the second rotating member 122 is a rotating shaft, a rotating cylinder is provided on the rear panel, the rotating shaft extends into the rotating cylinder, and rotates with the rotating cylinder, which can also realize the function of the second air duct body 121 rotating relative to the rear panel.

[0041] Further, the number of the second rotating members 122 is multiple, and the multiple second rotating members 122 are arranged on the second air duct body 121 in parallel and at intervals, and are all fixedly connected to the second air duct body 121.

The multiple second rotating members 122 can improve the rotation accuracy of the second air duct body 121 to ensure that the second air duct body 121 can rotate in the vertical direction as the axial direction. The multiple second rotating members 122 can also improve the support strength of the second air duct body 121 to ensure that the second air duct body 121 will not fall off the rear panel. In this embodiment, the number of the second rotating members 122 is two, and the two second rotating members 122 are relatively arranged at the two ends of the second air duct body 121, but it is not limited to this. In other embodiments, the number of the second rotating members 122 can be three, and can also be four, and the number of the second rotating members 122 is not specifically limited.

[0042] Please refer to Figure 5It should be noted that the first air duct 110 is provided with a first clamping structure 118, and the second air duct 120 is provided with a second clamping structure 123. The first clamping structure 118 is clamped with the second clamping structure 123 to achieve a detachable connection between the first air duct 110 and the second air duct 120, so as to facilitate opening or closing the air outlet cavity 160.

[0043] In this embodiment, the first snap-fit ​​structure 118 is an elastic snap-fit, the second snap-fit ​​structure 123 is a slot, the elastic snap-fit ​​is snap-fitted in the slot, the elastic snap-fit ​​can be separated from the slot under the action of external pressure, and the elastic snap-fit ​​can also be snap-fitted with the slot under the action of its own elastic force. However, it is not limited to this, in other embodiments, the first snap-fit ​​structure 118 can also be a slot, in which case the second snap-fit ​​structure 123 is an elastic snap-fit, the elastic snap-fit ​​is snap-fitted in the slot, and the snap-fitting of the first air duct 110 and the second air duct 120 can also be achieved.

[0044] Specifically, the elastic buckle is arranged at the top of the first air duct 110 and is located at the edge of the first air duct 110 on one side close to the second air duct 120, and the slot is arranged at the top of the second air duct 120 and is located at the edge of the second air duct 120 on one side close to the first air duct 110. When the first air duct 110 and the second air duct 120 are closed to close the air outlet cavity 160, the elastic buckle is engaged in the slot to fix the relative position of the first air duct 110 and the second air duct 120 to prevent the first air duct 110 from being separated from the second air duct 120, and the air duct assembly 100 can work normally at this time. When the first air duct 110 and the second air duct 120 are separated to open the air outlet cavity 160, the elastic buckle is separated from the slot, and at this time, the first air duct 110 and the second air duct 120 can be rotated with the vertical direction as the axis, so that the inner walls of the first air duct 110 and the second air duct 120 are exposed to the outside, which is convenient for cleaning.

[0045] Please continue to refer to Figure 1 In this embodiment, the first air duct 110 and the second air duct 120 are combined to form a volute 170, the front volute tongue 171 of the volute 170 is arranged on the first air duct 110, and the rear volute tongue 172 of the volute 170 is arranged on the second air duct 120, the front volute tongue 171 and the rear volute tongue 172 are arranged on both sides of the volute 170, and the front volute tongue 171 and the rear volute tongue 172 are used to guide the air flow direction in the volute 170, so that the air flow can pass through the air outlet cavity 160 and be blown out from the air outlet 111 to the room. Specifically, the volute 170 is split along a vertical plane to form the first air duct 110 and the second air duct 120, and the first air duct 110 and the second air duct 120 can be separated from or close to each other, so as to facilitate the disassembly and assembly of the air duct assembly 100.

[0046] When it is necessary to open the air outlet cavity 160 to clean the air duct assembly 100, first apply a force to the elastic buckle to overcome the elastic force of the elastic buckle so that the elastic buckle is disengaged from the slot, and then open the first air duct 110 outward. At this time, the first air duct 110 rotates relative to the rear panel and moves away from the second air duct 120. The first air duct 110 is separated from the second air duct 120 to open the air outlet cavity 160. The inner wall of the first air duct 110 is exposed to the outside, so that the drive motor 140, the crossflow blades 130 and the sweeping blades 150 on the first air duct 110 can be disassembled and assembled, and cleaned. Then open the second air duct 120 outward. At this time, the second air duct 120 rotates relative to the rear panel and moves away from the first air duct 110. The inner wall of the second air duct 120 is exposed to the outside, so that it is easy to clean.

[0047] After cleaning is completed, first close the second air duct 120 inward, at which time the second air duct 120 rotates relative to the rear panel and approaches the first air duct 110, and then close the first air duct 110 inward, at which time the first air duct 110 rotates relative to the rear panel and approaches the second air duct 120, until the first air duct 110 and the second air duct 120 are fitted together to close the air outlet cavity 160, and at the same time, apply force to the elastic buckle so that the elastic buckle is engaged in the slot, thereby fixing the relative positions of the first air duct 110 and the second air duct 120, and completing the installation of the air duct assembly 100.
