[0052] Figure 1 This is a schematic structural diagram of the rear service panel, air outlet shell, and air guide device of an air conditioner indoor unit according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 9 This utility model provides an indoor air conditioning unit 100, which includes a housing 110, an air outlet housing 120, and a first air guide plate 130.

[0053] A first outlet 112 is provided on the housing 110. An air outlet shell 120 is disposed on the housing 110 and located outside the first outlet 112 to receive airflow from the first outlet 112. The air outlet shell 120 has a first side plate 121, a second side plate 122, and a bottom plate 123. The first side plate 121 and the second side plate 122 are respectively disposed opposite to each other on the lateral sides of the first outlet 112, and the bottom plate 123 is disposed on the lower side of the first outlet 112. A first air guide plate 130 is movably disposed at the end of the first side plate 121 and the second side plate 122 opposite to the bottom plate 123.

[0054] Specifically, the first air guide plate 130 is located at the top of the air outlet shell 120, and the first outlet 112 can be located on the front or rear side of the shell 110. In this embodiment, the air guiding device includes the first air guide plate.

[0055] In this embodiment, after the airflow is output from the casing 110 of the indoor unit 100 through the first outlet 112, the airflow is further guided by the outer air outlet shell 120. The first side plate 121, the second side plate 122, and the bottom plate 123 of the air outlet shell 120 together form an extended guide channel, which constrains and guides the airflow in the lateral and bottom directions. The movable first air guide plate 130 located at the upper end of the two side plates can flexibly adjust the airflow direction at the end of the guide channel by rotating or swinging, thereby controlling the angle and range of the final airflow output.

[0056] In this embodiment, firstly, the first air guide plate 130 is installed on the outside of the housing 110 via the air outlet shell 120, making the assembly, disassembly, and maintenance of the first air guide plate 130 more convenient and reducing the difficulty and time cost of manual operation. Secondly, the extended airflow channel formed by the air outlet shell 120 prolongs the airflow acceleration path, and combined with the precise adjustment of the first air guide plate 130, effectively increases the air delivery distance. Thirdly, the modular design of the air outlet shell 120 separates the first air guide plate 130 from the housing 110, maintaining the compactness of the overall structure while expanding the adjustment angle range of the first air guide plate 130, thus adapting to more air delivery scenario requirements.

[0057] In some optional embodiments of this utility model, the air outlet shell 120 further has a third side plate, which is located at the end opposite to the first outlet of the first side plate 121 and the second side plate 122. By adding the third side plate, this embodiment enhances the overall structural strength of the air outlet shell 120, provides reliable support for multi-angle air guiding adjustment, and further expands the accuracy and adaptability of air supply control.

[0058] like Figures 1 to 4As shown, in some optional embodiments of this utility model, the indoor unit 100 of the air conditioner further includes a second air guide plate 140, which is rotatable to one end disposed on the first side plate 121 and the second side plate 122 opposite to the first outlet. Specifically, in this embodiment, the air outlet shell 120 does not have a third side plate, and the air outlet shell 120 can guide air through the first air guide plate 130 and the second air guide plate 140. The air guiding device includes a first air guide plate and a second air guide plate.

[0059] In this embodiment, the first air guide plate 130 and the second air guide plate 140 can rotate independently to form a dynamic air guiding surface, realizing multi-mode and multi-angle air delivery trajectory control. In other words, this embodiment expands the adjustable angle range of the airflow direction. During use, one or both of the first air guide plate 130 and the second air guide plate 140 can be selected for air guiding according to the user's airflow requirements.

[0060] Furthermore, the exposed layout of the dual air guide vanes facilitates disassembly and maintenance, balancing air delivery efficiency with ease of use.

[0061] like Figure 1 As shown, in some optional embodiments of this utility model, the first air guide plate 130 and the second air guide plate 140 are provided with a plurality of micropores.

[0062] In some optional embodiments of this utility model, the first air guide plate 130 is provided with first rotating shafts 131 at both ends, and the first rotating shafts 131 are located at the middle of the width direction of the first air guide plate 130. Specifically, the first rotating shafts 131 are connected to the first air guide plate 130 through a first mounting base.

[0063] like Figure 4 and Figure 5 As shown, in some optional embodiments of this utility model, the first air guide plate 130 is provided with a first rotating shaft 131 at both ends, and the first rotating shaft 131 is located at the end of the first air guide plate 130 away from the first outlet.

[0064] In this embodiment, the first rotating shaft 131 is located at the end of the air guide plate (away from the first outlet end), which can increase the swing angle range of the air guide plate and improve the airflow adjustment flexibility and air guiding efficiency.

[0065] like Figure 1 and Figure 4 As shown, in some optional embodiments of this utility model, there are multiple second air guide plates 140, which are distributed vertically along the first outlet; each second air guide plate 140 has a second rotating shaft 141 at both ends, and the second rotating shaft 141 is located in the middle of the width direction of the second air guide plate 140. Specifically, the second rotating shaft 141 is connected to the first air guide plate 130 through a first mounting base.

[0066] After the airflow enters the open air outlet shell 120 from the first outlet 112 of the shell 110, it is guided by the first side plate 121 and the second side plate 122 to form a directional flow. The first air guide plate 130 swings to adjust the airflow angle through the first rotating shaft 131, while multiple vertically distributed second air guide plates 140 rotate independently through the second rotating shaft 141 to achieve three-dimensional air delivery trajectory adjustment.

[0067] In some optional embodiments of this utility model, the first rotating shaft 131 is connected to the output end of the first motor. The first motor is used to drive the first air guide plate 130 to rotate automatically.

[0069] In some optional embodiments of this utility model, a first limiting structure is provided between the first air guide plate 130 and the air outlet shell 120 to limit the rotation angle of the first air guide plate 130.

[0070] In this embodiment, the first air guide plate 130 located at the top of the air outlet shell 120 can be manually rotated. By setting a first limiting structure, the rotation angle of the first air guide plate 130 can be controlled. For example, when the first air guide plate 130 is in the first position, its swing angle is 0°, the first air guide plate 130 is horizontally positioned, and the opening at the top of the air outlet shell 120 is closed; when the first air guide plate 130 is in the second position, its swing angle is 45°, opening the opening at the top of the air outlet shell 120 and guiding air upwards at an angle; when the first air guide plate 130 is in the third position, its swing angle is 90°, fully opening the opening at the top of the air outlet shell 120 and guiding air upwards.

[0071] In some optional embodiments of this utility model, a second limiting structure is provided between the second air guide plate 140 and the air outlet shell 120 to limit the rotation angle of the second air guide plate 140.

[0072] In this embodiment, the second air guide plate 140 located on the side of the air outlet shell 120 can be manually rotated. The rotation angle of the second air guide plate 140 can be controlled by setting a second limiting structure. For example, when the first air guide plate 130 is in the first preset position, its swing angle is 0°, the first air guide plate 130 is horizontally positioned, opening the opening on the rear or front side of the air outlet shell 120, and guiding airflow to the rear or front side of the air outlet shell 120; when the first air guide plate 130 is in the second preset position, its swing angle is 45°, guiding airflow diagonally upwards; when the first air guide plate 130 is in the third preset position, its swing angle is 90°, closing the opening on the rear or front side of the air outlet shell 120.

[0073] like Figure 1As shown, in some optional embodiments of this utility model, the first air guide plate 130 is provided with a first handle 132; the second air guide plate 140 is provided with a second handle 142. By providing the first handle 132 and the second handle 142, the rotation angle of the first air guide plate 130 and the second air guide plate 140 can be easily adjusted manually.

[0074] like Figures 4 to 8 As shown, in some optional embodiments of this utility model, the first limiting structure includes a first positioning part 133 and a first mounting hole 124. The first positioning part 133 is disposed on the outer peripheral wall of the first rotating shaft 131 and extends radially along the first rotating shaft 131. The first mounting hole 124 is disposed on the air outlet shell 120, and a plurality of first positioning grooves 1241 adapted to the first positioning part 133 are formed on the inner peripheral wall of the first mounting hole 124. The groove walls of the first positioning part 133 and / or the first positioning grooves 1241 are made of elastic material.

[0075] The second limiting structure includes a second positioning part 143 and a second mounting hole 125. The second positioning part 143 is disposed on the outer peripheral wall of the second rotating shaft 141 and extends radially along the second rotating shaft 141. The second mounting hole 125 is disposed on the air outlet shell 120, and a plurality of second positioning grooves 1251 adapted to the second positioning part 143 are formed on the inner peripheral wall of the second mounting hole 125. The groove walls of the second positioning part 143 and / or the second positioning grooves 1251 are made of an elastic material.

[0076] Specifically, a plurality of first protrusions are formed on the inner peripheral wall of the first mounting hole 124, and a first positioning groove 1241 is formed between adjacent first protrusions; the first protrusions and / or the first positioning portion 133 are made of elastic material. A plurality of second protrusions are formed on the inner peripheral wall of the second mounting hole 125, and a second positioning groove 1251 is formed between adjacent second protrusions; the second protrusions and / or the second positioning portion 143 are made of elastic material.

[0077] In use, the angle of the first air guide plate 130 can be adjusted by manually rotating the first air guide plate 130 so that the first positioning part 133 is located in the first positioning guide groove at a specific position. The angle of the second air guide plate 140 can also be adjusted by manually rotating the second air guide plate 140 so that the second positioning part 143 is located in the second positioning guide groove at a specific position.

[0078] like Figure 6 and Figure 7 As shown, in some optional embodiments of this utility model, the air outlet shell 120 is provided with a first insertion hole 126, the first insertion port is located outside the first mounting hole 124, and the first insertion hole 126 is coaxially arranged with the second mounting hole 125. The first rotating shaft 131 is inserted into the first insertion hole 126.

[0079] The air outlet housing 120 is provided with a second insertion hole 127, which is located outside the second mounting hole 125, and the second insertion hole 127 is coaxially arranged with the second mounting hole 125. The second rotating shaft 141 is inserted into the second insertion hole 127.

[0080] like Figure 5 and Figure 8 As shown, in some optional embodiments of the present invention, the first limiting structure further includes a third positioning part 134, which is connected to the end of the first positioning part 133 away from the first rotating shaft 131 and faces the first positioning groove 1241.

[0081] The second limiting structure also includes a fourth positioning part 144, which is connected to the end of the second positioning part 143 away from the second rotating shaft 141 and faces the second positioning groove 1251.

[0082] In this embodiment, by providing the third positioning part 134 and the fourth positioning part 144, the stability of the first limiting structure and the second limiting structure can be improved, and the rotation of the first air guide plate 130 or the second air guide plate 140 can be avoided by accidentally touching them.

[0083] In some optional embodiments of this utility model, both the third positioning part 134 and the fourth positioning part 144 are made of elastic material.

[0084] like Figure 3 and Figure 4 As shown, in some optional embodiments of this utility model, the middle portion of a plurality of second air guide plates 140 along their length is mounted on a connecting rod 150. By rotating one of the second air guide plates 140, the multiple second air guide plates 140 can rotate synchronously under the action of the connecting rod 150. In this embodiment, a second limiting structure is provided between one of the multiple second air guide plates 140 and the air outlet shell 120, and the remaining second rotating shafts 141 are inserted into the second insertion holes 127, which can be through holes.

[0085] like Figure 9 As shown, in some optional embodiments of this utility model, the first outlet 112 is located on the rear side of the housing 110; the air outlet housing 120 is located on the rear side of the first outlet 112. This embodiment helps to prevent the air blown out of the first outlet 112 from blowing directly on the user, which helps to improve the user experience.

[0086] like Figure 2As shown, in some optional embodiments of this utility model, a rear maintenance port is provided on the housing 110; the housing 110 includes a rear maintenance plate 111, which is disposed at the rear maintenance port, and a first outlet 112 is formed on the rear maintenance plate 111. The first outlet 112 is used to exhaust the air outlet of the fresh air purification device of the air conditioner indoor unit 100 into the room. Specifically, the air conditioner indoor unit 100 also includes a fresh air purification device, which is disposed inside the housing 110; the fresh air purification device has a second outlet, which is connected to and correspondingly disposed with the first outlet 112 on the housing 110.

[0087] In this embodiment, the rear maintenance plate 111 is connected to the housing 110 via a detachable structure (such as clips or screws). When maintenance is required, only the rear maintenance plate 111 needs to be removed to directly repair the internal components of the housing 110, without disassembling the entire housing, thus significantly shortening maintenance time. The first outlet 112 is located on the rear maintenance plate 111. When the rear maintenance plate 111 is removed, the air outlet shell 120, the first air guide plate 130, and the second air guide plate 140 can be cleaned or replaced simultaneously.

[0088] like Figure 2 As shown, in some optional embodiments of this utility model, the indoor unit 100 of the air conditioner further includes an air outlet grille 113, which is disposed at the first outlet 112, and the air outlet housing 120 is connected to the air outlet grille 113. In some alternative embodiments, the air outlet housing 120 is directly connected to the rear maintenance plate 111.

[0089] Specifically, the air outlet grille 113 has a mesh structure, comprising multiple horizontal bars and multiple vertical bars. The horizontal bars extend laterally along the first outlet 112 and are spaced vertically along the first outlet 112; the vertical bars extend vertically along the first outlet 112 and are spaced horizontally along the first outlet 112. The air outlet grille 113 increases the strength of the rear maintenance panel.

[0090] Compared to the method where the air outlet housing 120 is directly connected to the rear maintenance panel body, in this embodiment, the air outlet housing 120 is connected to the air outlet grille 113 and installed on the rear maintenance panel through the air outlet grille 113. The connection structure between the air outlet housing 120 and the air outlet grille 113 is hidden inside the air outlet housing 120, which makes the indoor unit 100 of the air conditioner look cleaner and significantly improves its aesthetics.

[0091] like Figure 2 and Figure 3 As shown, in some optional embodiments of this utility model, the air outlet housing 120 is provided with at least one set of latches 128. Each set of latches 128 includes a first latching part 1281 and a second latching part 1282 arranged vertically opposite to each other, so as to latch the air outlet housing 120 onto the air outlet grille 113. Specifically, the air outlet housing 120 is latched onto the crossbar of the air outlet grille 113.

[0092] In this embodiment, the air outlet housing 120 is snapped onto the air outlet grille 113 via a bayonet, which has the advantage of facilitating assembly and disassembly.

[0093] In some alternative embodiments of this utility model, the air outlet shell 120 is connected to the air outlet grille 113 by heat fusion or threaded connection.

[0094] In some optional embodiments of this utility model, the fresh air purification device includes a housing, a purification device, and a second outlet. A duct for airflow is formed within the housing; the housing has a first inlet for introducing outdoor fresh air into the duct and a second inlet for introducing indoor return air into the duct; the purification device is disposed within the duct and is used to purify the outdoor fresh air and / or indoor return air flowing into the duct.

The first outlet 112 is disposed on the rear side of the housing 110 and corresponds to the second outlet. The housing 110 has a first notch corresponding to the first inlet for the passage of a fresh air duct; the housing 110 also has a second notch corresponding to the second inlet for connecting the second inlet and the indoor space.

[0095] When the air conditioner is running, outdoor fresh air enters the duct through the first inlet, and indoor return air is simultaneously drawn in through the second inlet. The two are mixed in the duct and then filtered and purified by a purification device (such as a HEPA filter). The purified airflow enters the rear of the indoor unit 100 of the air conditioner from the second outlet and the first outlet 112, thereby avoiding the purified fresh air from blowing directly on the user and improving the user experience.

[0096] In some optional embodiments of this utility model, the fresh air purification device is installed at the bottom inside the housing 110 of the indoor unit 100 of the air conditioner.

[0097] In some optional embodiments of this utility model, both the first inlet and the second inlet are located on the rear side of the outer casing; the second outlet is located above the first inlet and the second inlet.

[0098] In this embodiment, the first inlet, the second inlet, and the second outlet are all located on the rear side of the casing. The concealed design avoids the exposure of external pipes and improves the overall aesthetics of the machine.

[0099] In some optional embodiments of this utility model, the air conditioner indoor unit 100 is a vertical air conditioner indoor unit.

[0100] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
