DETAILED DESCRIPTION

[0029] 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.

[0030] Example

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the present invention provides an air conditioner 100 for regulating indoor temperature. It can increase the opening angle of the air outlet cavity 180, facilitate disassembly and assembly, improve disassembly and assembly efficiency, and facilitate cleaning. In this embodiment, the air conditioner 100 is a vertical air conditioner, and the air conditioner 100 is placed vertically indoors. The air conditioner 100 can blow hot air or cold air into the room to regulate the indoor temperature.

[0032] The air conditioner 100 includes a front panel 110, a rear panel 120, a first air duct 130, a second air duct 140, a crossflow blade 150, a drive motor 160 and a guide blade 170. The front panel 110 is hinged to the rear panel 120, and the front panel 110 can rotate relative to the rear panel 120. The first air duct 130 is fixedly connected to the inner side of the front panel 110. When the front panel 110 rotates relative to the rear panel 120, it can drive the first air duct 130 to rotate relative to the rear panel 120. The second air duct 140 is hinged to the rear panel 120, and the second air duct 140 can rotate relative to the rear panel 120. Specifically, the front panel 110 and the second air duct 140 are hinged to the two ends of the rear panel 120, that is, one end of the rear panel 120 is hinged to the front panel 110, and the other end is hinged to the second air duct 140. The first air duct 130 and the second air duct 140 are detachably connected and combined to form an air outlet cavity 180, and the air outlet cavity 180 is used for air flow to pass through, and the first air duct 130 and the second air duct 140 can guide the air flow to blow out indoors. The front panel 110 can drive the first air duct 130 to rotate relative to the rear panel 120, so that the first air duct 130 and the second air duct 140 are separated, thereby opening the air outlet cavity 180, so that the inner wall of the first air duct 130 is exposed to the outside, and the second air duct 140 can rotate relative to the rear panel 120 after the first air duct 130 rotates to open the air outlet cavity 180, so that the inner wall of the second air duct 140 is exposed to the outside, and the first air duct 130 and the second air duct 140 can open the air outlet cavity 180 at the same time to increase the opening angle of the air outlet cavity 180, so as to facilitate the disassembly and assembly of the air conditioner 100, improve the disassembly and assembly efficiency, and facilitate cleaning.

[0033] In this embodiment, the front panel 110 can rotate relative to the rear panel 120 in a first direction to drive the first air duct 130 to open the air outlet cavity 180, and the second air duct 140 can rotate relative to the rear panel 120 in a second direction to open the air outlet cavity 180. The first direction is opposite to the second direction to further increase the opening angle of the air outlet cavity 180, which is convenient for disassembly, assembly and cleaning. Specifically, the first direction is a horizontal left direction, and the second direction is a horizontal right direction, that is, the front panel 110 can drive the first air duct 130 to rotate leftward, and the second air duct 140 can rotate rightward to open the air outlet cavity 180.

[0034] It should be noted that the front panel 110 and the rear panel 120 are both arranged in an arc shape, and the entire air conditioner 100 is cylindrical. The front panel 110 and the rear panel 120 are combined to form a circular cavity 190. The first air duct 130 and the second air duct 140 are both arranged in the circular cavity 190, that is, the air outlet cavity 180 is arranged in the circular cavity 190, and the front panel 110 can rotate relative to the rear panel 120 to open or close the circular cavity 190. Specifically, since the first air duct 130 is fixedly connected to the front panel 110, when the front panel 110 opens or closes the circular cavity 190, the first air duct 130 will also open or close the air outlet cavity 180, which is convenient and quick.

[0035] The driving motor 160 and the crossflow blades 150 are both installed on the first air duct 130. The driving motor 160 is connected to the crossflow blades 150. The driving motor 160 can drive the crossflow blades 150 to rotate to drive the air to form an airflow. The crossflow blades 150 are arranged in the air outlet cavity 180. The crossflow blades 150 can suck the outside air into the air outlet cavity 180 to form an airflow. In this process, the airflow will pass through the evaporator (not shown) arranged in the air conditioner 100 to achieve the cooling or heating function of the airflow. The first air duct 130 is provided with an air outlet 131 connected to the air outlet cavity 180. The crossflow blades 150 can also drive the airflow to be blown out from the air outlet 131 into the room to adjust the indoor temperature. The guide blades 170 are installed in the air outlet 131. The guide blades 170 are used to adjust the air outlet direction. Furthermore, the front panel 110 is provided with an air vent 111 , the position of the air vent 111 corresponds to the position of the air outlet 131 , and the air flow blown out from the air outlet 131 can enter the room through the air vent 111 to adjust the indoor temperature.

[0036] It is worth noting that the driving motor 160, the crossflow blades 150 and the guide blades 170 are all arranged on the first air duct 130. When the front panel 110 drives the first air duct 130 to rotate relative to the rear panel 120, the driving motor 160, the crossflow blades 150 and the guide blades 170 will also rotate with the first air duct 130. When the first air duct 130 rotates to the first extreme position, the inner wall of the first air duct 130 is completely exposed to the outside. At this time, the driving motor 160, the crossflow blades 150 and the guide blades 170 are also exposed to the outside. The user can easily remove the driving motor 160, the crossflow blades 150 and the guide blades 170 from the first air duct 130 or install the first air duct 130, which is convenient and quick. Further, the second air duct 140 can rotate relative to the rear panel 120 after the first air duct 130 is opened. When the second air duct 140 rotates to the second extreme position, the inner wall of the second air duct 140 is completely exposed to the outside. In this way, the disassembly and assembly process of the entire air conditioner 100 is simple, with fewer disassembly and assembly parts and steps, high disassembly and assembly efficiency, and it is convenient to clean the first air duct 130 and the second air duct 140 in the air conditioner 100.

[0037] In this embodiment, the axis of the hinged connection between the rear panel 120 and the front panel 110 and the axis of the hinged connection between the rear panel 120 and the second air duct 140 are arranged in parallel, that is, the axis of the rotation of the first air duct 130 relative to the rear panel 120 and the axis of the rotation of the second air duct 140 relative to the rear panel 120 are arranged in parallel, so as to realize the separation or closing of the first air duct 130 and the second air duct 140, thereby opening or closing the air outlet cavity 180. Specifically, the axis of the hinged connection between the rear panel 120 and the front panel 110 extends in the vertical direction, that is, the front panel 110 can rotate relative to the rear panel 120 with the vertical direction as the axial direction, and in the process of rotation, the first air duct 130 is driven to separate from the second air duct 140 and open the air outlet cavity 180. The axis of the hinged connection between the rear panel 120 and the second air duct 140 extends in the vertical direction, that is, the second air duct 140 can rotate relative to the rear panel 120 with the vertical direction as the axial direction. In addition, the axial direction of the crossflow blade 150 is also in the vertical direction, and the axis of the crossflow blade 150 is arranged parallel to and spaced from the axis of rotation of the front panel 110 relative to the rear panel 120. However, this is not limited to this. In other embodiments, the axis of the hinge connection between the rear panel 120 and the front panel 110 may also extend obliquely to the vertical direction, and the axis of the hinge connection between the rear panel 120 and the front panel 110 may also extend in the horizontal direction. The extending direction of the axis of the hinge connection between the rear panel 120 and the front panel 110 is not specifically limited.

[0038] Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8It is worth noting that the front panel 110 is provided with a first hinge structure 112, and the rear panel 120 is provided with a second hinge structure 121. The first hinge structure 112 and the second hinge structure 121 are rotatably matched to realize the function of the front panel 110 rotating relative to the rear panel 120. In this embodiment, the first hinge structure 112 is a rotating shaft 113, and the second hinge structure 121 is a fixed cylinder 122. The rotating shaft 113 extends into the fixed cylinder 122 and can rotate relative to the fixed cylinder 122. The fixed cylinder 122 can limit the rotating shaft 113 to prevent the rotating shaft 113 from being separated from the fixed cylinder 122. The axial directions of the rotating shaft 113 and the fixed cylinder 122 are the same and both are in the vertical direction. However, it is not limited to this. In other embodiments, the first hinge structure 112 is a fixed tube 122, and the second hinge structure 121 is a rotating shaft 113. The rotating shaft 113 extends into the fixed tube 122 and rotates with the fixed tube 122, which can also realize the function of rotating the front panel 110 relative to the rear panel 120.

[0039] The rotating shaft 113 includes a limiting portion 114 and a rotating portion 115. The limiting portion 114 is coaxially arranged with the rotating portion 115 and fixedly connected. In this embodiment, the limiting portion 114 and the rotating portion 115 are integrally formed to improve the connection strength. The diameter of the limiting portion 114 is larger than the diameter of the rotating portion 115, and the diameter of the rotating portion 115 is smaller than the inner diameter of the fixed cylinder 122. The diameter of the limiting portion 114 is larger than the inner diameter of the fixed cylinder 122. The rotating portion 115 extends into the fixed cylinder 122 and can rotate relative to the fixed cylinder 122. The limiting portion 114 abuts against the end wall of the fixed cylinder 122 to prevent the rotating shaft 113 from being separated from the fixed cylinder 122. Specifically, the limiting portion 114 is arranged above the rotating portion 115, and the rotating portion 115 can be inserted into the fixed tube 122 from top to bottom until the limiting portion 114 abuts against the end wall of the fixed tube 122. At this time, the limiting portion 114 can support the front panel 110 to prevent the front panel 110 from falling relative to the rear panel 120 under the action of gravity.

[0040] It should be noted that there are multiple rotating shafts 113 and multiple fixed cylinders 122, and multiple rotating shafts 113 are coaxially arranged, and each rotating shaft 113 cooperates with one fixed cylinder 122. Multiple rotating shafts 113 are arranged on the front panel 110 at intervals, and the front panel 110 can rotate relative to the rear panel 120 through the one-to-one cooperation between multiple rotating shafts 113 and multiple fixed cylinders 122. Multiple rotating shafts 113 can improve the rotation accuracy of the front panel 110 to ensure that the front panel 110 can rotate with the vertical direction as the axial direction. Multiple rotating shafts 113 can also improve the supporting strength of the front panel 110 to ensure that the front panel 110 will not fall off the rear panel 120. In this embodiment, the number of rotating shafts 113 and the number of fixed cylinders 122 are both two, and the two rotating shafts 113 are relatively arranged at the two ends of the front panel 110, but it is not limited to this. In other embodiments, the number of rotating shafts 113 and the number of fixed cylinders 122 can be three or four, and the number of rotating shafts 113 and the number of fixed cylinders 122 are not specifically limited.

[0041] The second air duct 140 includes an air duct body 141 and a rotating member 142. The air duct body 141 is fixedly connected to the rotating member 142, and the rotating member 142 is hinged to the rear panel 120. The air duct body 141 is detachably connected to the first air duct 130, and the air duct body 141 and the first air duct 130 are combined to form an air outlet cavity 180. The rotating member 142 can rotate relative to the rear panel 120 to drive the air duct body 141 to rotate relative to the rear panel 120. At the same time, the rotating member 142 can also support the air duct body 141 to prevent the air duct body 141 from falling off the rear panel 120.

[0042] In this embodiment, the air duct body 141 and the rotating member 142 are integrally formed to improve the connection strength, but not limited thereto, in other embodiments, the air duct body 141 and the rotating member 142 are separately provided and fixedly connected together by screws or other connecting members for easy processing and production.

[0043] In this embodiment, the rotating member 142 is provided with a rotating groove 143, and the rear panel 120 is provided with a rotating shaft 123. The axial direction of the rotating groove 143 is the same as the axial direction of the rotating shaft 123, and both are in the vertical direction. The rotating shaft 123 extends into the rotating groove 143 and cooperates with the rotating groove 143. The rotating groove 143 can limit the rotating shaft 123 to prevent the rotating shaft 123 from being separated from the rotating groove 143. However, it is not limited to this. In other embodiments, the rotating member 142 is provided with a rotating shaft 123, and the rear panel 120 is provided with a rotating groove 143. The rotating shaft 123 and the rotating groove 143 are rotatably matched, and the function of the air duct body 141 rotating relative to the rear panel 120 can also be realized.

[0044] Further, there are multiple rotating members 142, which are arranged on the air duct body 141 in parallel and at intervals, and are all fixedly connected to the air duct body 141. The air duct body 141 can be rotated relative to the rear panel 120 by the multiple rotating members 142 at the same time. The multiple rotating members 142 can improve the rotation accuracy of the air duct body 141 to ensure that the air duct body 141 can rotate in the vertical direction as the axial direction. The multiple rotating members 142 can also improve the support strength of the air duct body 141 to ensure that the air duct body 141 will not fall off the rear panel 120. In this embodiment, there are two rotating members 142, and the two rotating members 142 are relatively arranged at the two ends of the air duct body 141, but it is not limited thereto. In other embodiments, the number of the rotating members 142 can be three or four, and the number of the rotating members 142 is not specifically limited.

[0045] Please refer to Fig. 9 In this embodiment, the first air duct 130 is provided with a buckle 132, and the second air duct 140 is provided with a slot 144, and the buckle 132 is engaged with the slot 144 to achieve a detachable connection between the first air duct 130 and the second air duct 140, so as to facilitate opening or closing the air outlet cavity 180. The buckle 132 is engaged in the slot 144, and the buckle 132 can be separated from the slot 144 under the action of external pressure, and the buckle 132 can also be engaged with the slot 144 under the action of its own elastic force. However, it is not limited to this. In other embodiments, the first air duct 130 is provided with a slot 144, and the second air duct 140 is provided with a buckle 132, and the buckle 132 cooperates with the slot 144, so as to achieve the same connection between the first air duct 130 and the second air duct 140.

[0046] Specifically, the buckle 132 is disposed at the top of the first air duct 130 and is located at the edge of the first air duct 130 on one side close to the second air duct 140, and the slot 144 is disposed at the top of the second air duct 140 and is located at the edge of the second air duct 140 on one side close to the first air duct 130. When the first air duct 130 and the second air duct 140 are closed to close the air outlet cavity 180, the buckle 132 is engaged in the slot 144 to fix the relative position of the first air duct 130 and the second air duct 140, and prevent the first air duct 130 from being separated from the second air duct 140, thereby fixing the relative position of the front panel 110 and the rear panel 120, and the air conditioner 100 can work normally at this time. When the first air duct 130 and the second air duct 140 are separated to open the air outlet cavity 180, the buckle 132 disengages from the slot 144. At this time, the first air duct 130 can rotate in the vertical direction as the axis driven by the front panel 110, and the second air duct 140 can also rotate in the vertical direction as the axis, so that the inner walls of the first air duct 130 and the second air duct 140 are exposed to the outside for easy cleaning.

[0047] When it is necessary to open the air conditioner 100 for cleaning, first remove the buckle 132 from the slot 144 so that the buckle 132 is disengaged from the slot 144, and then the front panel 110 is rotated outward relative to the rear panel 120 to open the circular cavity 190. During this process, the first air duct 130 is rotated outward under the drive of the front panel 110 and away from the second air duct 140. The first air duct 130 is separated from the second air duct 140 to open the air outlet cavity 180, so that the inner wall of the first air duct 130 is exposed to the outside, which is convenient for disassembly and assembly of the drive motor 160, the crossflow fan blades 150 and the guide blades 170 on the first air duct 130 for easy cleaning. Then the second air duct 140 is rotated outward relative to the rear panel 120 and away from the first air duct 130, so that the inner wall of the second air duct 140 is exposed to the outside, which is convenient for cleaning.

[0048] After cleaning is completed, first rotate the second air duct 140 inward relative to the rear panel 120 and approach the first air duct 130, then rotate the front panel 110 inward relative to the rear panel 120, and the first air duct 130 is also rotated inward driven by the front panel 110 and approaches the second air duct 140. When the first air duct 130 and the second air duct 140 are abutted, the air outlet cavity 180 is closed. At this time, the front panel 110 and the rear panel 120 are abutted, and the circular cavity 190 is closed synchronously. At the same time, the buckle 132 is snapped into the slot 144 to fix the relative position of the first air duct 130 and the second air duct 140, thereby fixing the relative position of the front panel 110 and the second air duct 140, and then fixing the relative position of the front panel 110 and the rear panel 120, and completing the installation of the air conditioner 100.

[0049] The air conditioner 100 described in the embodiment of the present invention has a front panel 110 and a rear panel 120 hinged together, a first air duct 130 fixedly connected to the inner side of the front panel 110, and a second air duct 140 hinged to the rear panel 120.
