DETAILED DESCRIPTION

[0037] In the prior art, the rotation control of the air guide plate assembly has no feedback. Due to wear of the drive box during use or changes in execution accuracy, the air guide plate assembly may collide and wear with the middle frame during rotation, causing damage to the air guide plate assembly and abnormal noise.

[0038] 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.

[0039] like Figure 1 As shown, this embodiment provides an air conditioner, which includes an indoor unit 100 and an outdoor unit (not shown in the figure). The indoor unit 100 is connected to the outdoor unit through a pipeline (not shown in the figure) to adjust parameters such as temperature, humidity, and flow rate of the ambient air in a building or structure.

[0040] Please refer to Figure 2 and Figure 3 In this embodiment, the indoor unit 100 includes a middle frame 110 and an air guide plate assembly 150. The air guide plate assembly 150 is rotatably mounted on the middle frame 110. The air guide plate assembly 150 has a first position and a second position. A limiting portion 111 is provided on the middle frame 110, and the limiting portion 111 includes a first wall surface 113 and a second wall surface 115. A matching portion 151 is provided on the air guide plate assembly 150. When the air guide plate assembly 150 is in the first position, the matching portion 151 abuts against the first wall surface 113. When the air guide plate assembly 150 is in the second position, the matching portion 151 abuts against the second wall surface 115.

[0041] In this embodiment, by setting a limiting portion 111 on the middle frame 110 and a matching portion 151 on the air deflector assembly 150, the limiting portion 111 and the matching portion 151 cooperate to achieve the restriction of the air deflector assembly 150, thereby avoiding the collision and wear of the air deflector assembly 150 and the middle frame 110, and improving the problem of damage or abnormal noise of the air deflector assembly 150. When the air deflector assembly 150 is in the first position, the matching portion 151 is used to abut against the first wall 113 of the limiting portion 111, thereby avoiding the collision and wear of the air deflector assembly 150 and the middle frame 110 when in the first position. When the air deflector assembly 150 is in the second position, the matching portion 151 is used to abut against the second wall 115 of the limiting portion 111, thereby avoiding the collision and wear of the air deflector assembly 150 and the middle frame 110 when in the second position, and improving the problem of collision, wear and abnormal noise of the air deflector assembly 150 and the middle frame 110.

[0042] In this embodiment, the first position of the air deflector assembly 150 represents a position when the air deflector assembly 150 is fully opened, and the second position of the air deflector assembly 150 represents a position when the air deflector assembly 150 is fully closed.

[0043] In some other embodiments of the present application, the first position and the second position may also represent the position of the preset opening of the air deflector assembly 150. For example, the first position may represent the position of the air deflector assembly 150 when the air deflector assembly 150 is 95% open, and the second position may also represent the position of the air deflector assembly 150 when the air deflector assembly 150 is 1% open. The first position and the second position may also represent the extreme open position and the extreme closed position of the air deflector assembly 150. The extreme open position and the extreme closed position are two extreme positions designed for the air deflector assembly, and these two extreme positions are not the normally open and normally closed positions of the air deflector assembly 150.

[0044] Please refer to Figure 1 and Figure 4 In this embodiment, the middle frame 110 is provided with an air outlet 117 , and the air guide plate assembly 150 is enclosed in the air outlet 117 . When in use, the air guide plate assembly 150 is used to guide the wind of the air outlet 117 .

[0045] Please continue to refer to Figure 3In this embodiment, the matching portion 151 has a third wall surface 153 and a fourth wall surface 155. When the air deflector assembly 150 is in the first position, the third wall surface 153 abuts against the first wall surface 113. When the air deflector assembly 150 is in the second position, the fourth wall surface 155 abuts against the second wall surface 115. When the air deflector assembly 150 is in the first position, the third wall surface 153 of the matching portion 151 abuts against the first wall surface 113 of the limiting portion 111, which can increase the contact area between the limiting portion 111 and the matching portion 151, thereby better improving the limiting effect of the air deflector assembly 150 in the first position. When the air deflector assembly 150 is in the second position, the fourth wall surface 155 of the matching portion 151 abuts against the second wall surface 115 of the limiting portion 111, which can increase the contact area between the limiting portion 111 and the matching portion 151, thereby better improving the limiting effect of the air deflector assembly 150 in the second position.

[0046] Please refer to Figure 1 , Figure 4 and Figure 5 In this embodiment, the outer side of the middle frame 110 is provided with a mounting groove 119 inwardly recessed. The mounting groove 119 extends along the length direction of the air outlet 117. The air guide plate assembly 150 is rotatably mounted on the mounting groove 119. The limiting portion 111 is protruded from the bottom wall of the mounting groove 119. Providing the mounting groove 119 on the middle frame 110 can better facilitate the installation of the air guide plate assembly 150, and protruding the limiting portion 111 on the bottom wall of the mounting groove 119 can better cooperate with the matching portion 151, and also facilitate the molding of the limiting portion 111.

[0047] In some embodiments of the present application, the limiting portion 111 may also be recessed in the side wall of the mounting groove 119. When the limiting portion 111 is recessed in the bottom wall of the mounting groove 119, the matching portion 151 may be convexly disposed on the air deflector assembly 150 and extend into the limiting portion 111 to limit the first position and the second position of the air deflector assembly 150.

[0048] In some other embodiments of the present application, the mounting groove 119 may also be recessed in the side wall or other positions of the air outlet 117 .

[0049] Please refer to Figure 6 and Figure 7 In this embodiment, the matching portion 151 is protruded from the air deflector assembly 150. Protruding the matching portion 151 from the air deflector assembly 150 allows the matching portion 151 to better match the limiting portion 111 without weakening the strength of the air deflector assembly 150.

[0050] In some other embodiments of the present application, the matching portion 151 may also be recessed in the air guide plate assembly 150. When the air guide plate assembly 150 is recessed, the limiting portion 111 may be protruded in the mounting groove 119 and extend into the matching portion 151 to limit the first position and the second position of the air guide plate assembly 150 to avoid collision between the air guide plate assembly 150 and the middle frame 110.

[0051] Please refer to Figure 5 , Figure 6 and Figure 7 In this embodiment, the air deflector assembly 150 includes an air deflector 157 and a rotating shaft 159. The rotating shaft 159 is mounted on the air deflector 157, and the rotating shaft 159 rotatably mounts the air deflector assembly 150 on the mounting groove 119. The matching portion 151 is protruded from the rotating shaft 159, so that the matching portion 151 and the rotating shaft 159 rotate simultaneously along the same rotation center, so that the matching portion 151 and the limiting portion 111 cooperate to limit the first position and the second position of the air deflector assembly 150.

[0052] Please refer to Figure 4 and Figure 6 In this embodiment, a cylindrical mounting portion 161 is formed on the side wall of the air guide 157 along the length direction. The mounting groove 119 is in an arc shape, and the cross section of the mounting groove 119 is in a semicircular arc shape. The mounting portion 161 is partially accommodated in the mounting groove 119, and the diameter of the mounting groove 119 is slightly larger than the diameter of the mounting portion 161, so as to avoid contact and wear between the mounting portion 161 and the mounting groove 119. The rotating shaft 159 is arranged at the end of the mounting portion 161, and the rotating shaft 159 is coaxial with the mounting portion 161, so that the rotating shaft 159 and the mounting portion 161 can rotate along the same rotation axis 159 line.

[0053] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, there are two rotating shafts 159, and the two rotating shafts 159 are respectively installed at the two ends of the mounting portion 161. There are two limiting portions 111, and the two limiting portions 111 are protruding at the two ends of the mounting groove 119. After the air deflector assembly 150 is installed in the mounting groove 119, the two limiting portions 111 are respectively located at the two ends of the mounting portion 161. A through groove 121 is provided on each of the two limiting portions 111. The rotating shaft 159 is rotatably installed in the through groove 121. The deformation of the air deflector assembly 150 can be avoided by the two limiting portions 111 cooperating with the matching portions 151 on the two rotating shafts 159. The through groove 121 is provided on the limiting portion 111 to facilitate the rotation shaft 159 to pass through. The through groove 121 and the rotating shaft 159 cooperate to achieve the pre-positioning of the air deflector assembly 150 when installed in the air deflector assembly 150.

[0054] In some other embodiments of the present application, the rotating shaft 159 may also be one, and one rotating shaft 159 is disposed at one end of the mounting portion 161. The other end of the mounting portion 161 may be rotatably mounted in the mounting groove 119 by means of shaft-hole matching or the like.

[0055] Please refer to Figure 5 and Figure 7 In this embodiment, the matching portion 151 is protruded from the side wall of the rotating shaft 159. The third wall surface 153 and the fourth wall surface 155 are two opposite side walls of the matching portion 151, and the third wall surface 153 and the fourth wall surface 155 are respectively connected to the side wall of the rotating shaft 159. The first wall surface 113 and the second wall surface 115 are located on both sides of the through groove 121. This makes it more convenient to set the first wall surface 113 and the second wall surface 115, and can also avoid interference when the air guide plate assembly 150 is installed.

[0056] In some other embodiments of the present application, the matching portion 151 may also be protruded from the end of the rotating shaft 159 and cooperate with the protruded limiting portion 111 to achieve the limitation of the first position and the second position of the air deflector assembly 150. Alternatively, the matching portion 151 protrudes from the side wall of the mounting portion 161 and cooperates with the limiting portion 111 protruded from the bottom wall of the mounting groove 119 to limit the first position and the second position of the air deflector assembly 150.

[0057] Please continue to refer to Figure 5 and Figure 7 In this embodiment, the rotating shaft 159 includes a first section 163 and a second section 165 connected to each other. The first section 163 is protruded from the end of the mounting portion 161. The matching portion 151 is protruded from the side wall of the second section 165. The through slot 121 includes a first slot section 123 and a second slot section 125. The first wall surface 113 and the second wall surface 115 are respectively located on both sides of the second slot section 125, and the first wall surface 113 and the second wall surface 115 are both connected to the side wall of the second slot section 125. The first section 163 is installed on the first slot section 123, and the second section 165 is installed on the second slot section 125. By arranging the first section 163 and the first slot section 123 to cooperate, the position of the air deflector assembly 150 can be pre-positioned when the air deflector assembly 150 is installed, so that the axis of the mounting portion 161 roughly coincides with the axis of the mounting slot 119, ensuring that the mounting portion 161 rotates better in the mounting slot 119. At the same time, the installation accuracy of the matching portion 151 can be ensured, so that the position definition accuracy of the air guide plate assembly 150 is higher.

[0058] In this embodiment, the diameter of the first section 163 is larger than the diameter of the second section 165. The diameter of the first slot section 123 is larger than the diameter of the second slot section 125. The diameter of the first section 163 is larger than the diameter of the second end so that the rotating shaft 159 forms a stepped shaft. The diameter of the second slot section 125 is larger than the diameter of the first slot section 123 so that the through slot 121 forms a stepped slot, so that the step of the rotating shaft 159 and the step of the through slot 121 cooperate to predefine the left and right positions of the air deflector assembly 150, thereby facilitating the installation of the air deflector assembly 150.

[0059] Please refer to Figure 8 and Fig. 9 In this embodiment, the first section 163 is loosely assembled in the first slot section 123. That is, the diameter of the first end is slightly smaller than the diameter of the first slot section 123 and the length of the first section 163 is slightly smaller than the length of the first slot section 123. The loose assembly of the first section 163 and the first slot section 123 prevents the first section 163 from rubbing against the side wall of the first slot section 123 during rotation, thereby avoiding wear of the first section 163 or the first slot section 123.

[0060] In this embodiment, the second section 165 is loosely assembled in the second slot section 125. That is, the diameter of the second section 165 is slightly smaller than the diameter of the second slot section 125. The loose assembly of the second section 165 and the second slot section 125 prevents the second section 165 from rubbing against the side wall of the second slot section 125 during rotation, thereby avoiding wear of the second section 165 or the second slot section 125.

[0061] Please refer to Figure 1 , Figure 8 and Fig. 9 In this embodiment, the indoor unit 100 further includes a drive box 170. A slot 127 is provided on the middle frame 110. The slot 127 is located on one side of the limiting portion 111 close to the end of the middle frame 110. The drive box 170 is mounted on the middle frame 110, and the drive box 170 extends out of the slot 127 and is connected to the second end to drive the air deflector assembly 150 to rotate. By extending the drive box 170 from the middle frame 110 to connect with the air deflector assembly 150, it is convenient to better assemble the air deflector assembly 150 on the middle frame 110.

[0062] In this embodiment, a polygonal connection hole 167 is recessed at the end of the second section 165, and the drive box 170 has a polygonal drive shaft 171, which extends into the connection hole 167 to drive the air guide assembly 150 to rotate. A multi-deformable hole is provided at the end of the second section 165 to connect with the drive shaft 171, thereby preventing the drive shaft 171 from interfering with and affecting the mating portion 151 when connected to the second section 165.

[0063] The working principles and beneficial effects of the indoor unit 100 and the air conditioner provided in this embodiment include:

[0064] In this embodiment, by setting a limiting portion 111 on the middle frame 110 and a matching portion 151 on the air deflector assembly 150, the limiting portion 111 and the matching portion 151 cooperate to achieve the restriction of the air deflector assembly 150, thereby avoiding the collision and wear of the air deflector assembly 150 and the middle frame 110, and improving the problem of damage or abnormal noise of the air deflector assembly 150. When the air deflector assembly 150 is in the first position, the matching portion 151 is used to abut against the first wall 113 of the limiting portion 111, thereby avoiding the collision and wear of the air deflector assembly 150 and the middle frame 110 when in the first position. When the air deflector assembly 150 is in the second position, the matching portion 151 is used to abut against the second wall 115 of the limiting portion 111, thereby avoiding the collision and wear of the air deflector assembly 150 and the middle frame 110 when in the second position, and improving the problem of collision, wear and abnormal noise of the air deflector assembly 150 and the middle frame 110.

[0065] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
