Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an air deflector structure and an air conditioner. Background Art

[0002] In existing split wall-mounted air conditioners, a rotatable air deflector is usually provided at the air outlet of the air conditioner to guide the air flow. Generally, in the cooling mode, the angle of the air deflector is horizontal or upward, so that the cold air rises to achieve rapid cooling; in the heating mode, the angle of the air deflector is downward, so that the hot air descends to achieve rapid heating. Different users have different choices for heating and cooling in different scenarios, and also have different requirements for direct blowing or avoiding direct blowing. Therefore, the angle of the air deflector should be able to rotate within a large range as much as possible to meet different scenarios and different requirements. Usually, the blowing angle is adjusted by adjusting the angle of the air deflector to meet different usage scenarios of the air conditioner.

[0003] Existing air deflectors usually include a main board and a sub-board. The main board is wider so that the air flow can be more concentrated and the air supply can be farther. The sub-board is narrower than the main board and plays an auxiliary guiding role. The main board and the sub-board are designed as an integral structure. Since their relative positions remain unchanged, the existing air deflector usually can only be rotated and opened forward, and the rotation angle of the air deflector is limited, and it is impossible to achieve large-angle downward air supply. Summary of the Invention

[0004] The first object of the present invention is to provide an air deflector structure to solve the technical problem that the rotation angle of the air deflector of the air conditioner is limited and large-angle downward air supply cannot be achieved.

[0005] The air deflector structure is arranged at the air outlet of the air conditioner housing, and includes a main board and a sub-board; the sub-board can be rotatably connected to the housing; both the left and right sides of the main board can be slidably connected to the housing and can slide on the housing along a first preset track, and the main board is slidably connected to the sub-board and can slide on the sub-board along a second preset track;

[0006] During the process of the main board opening the air outlet, the main board rotates with the sub-board and slides outward on the sub-board along the second preset track under the limiting action of the first preset track.

[0007] During the process of opening the air outlet of the main board, the auxiliary board rotates. In addition to rotating with the auxiliary board, the main board slides relative to the frame and the auxiliary board simultaneously. That is, the movement trajectory of the main board relative to the frame is the first preset trajectory. Under the limiting effect of the first preset trajectory, it slides outward on the auxiliary board along the second preset trajectory, thus relieving the interference limitation between the upper edge of the main board and the upper edge of the air outlet of the frame. Furthermore, the upward rotation of the auxiliary board and the main board can be realized, and the interference limitation between the lower edge of the main board and the lower edge of the air outlet of the frame can also be relieved, thereby realizing the downward rotation of the auxiliary board and the main board until reaching the limit position state in the corresponding rotation direction. At this time, the main board reaches the maximum swing angle in the corresponding rotation direction. In addition, since the main board slides outward on the auxiliary board during the process of opening the air outlet, the air supply distance is increased. Thus, large-angle and long-distance air supply can be achieved.

[0008] Further, first guiding grooves are symmetrically arranged at the parts of the frame on the left and right sides of the air outlet. Slide shafts are arranged on the left and right sides of the main board. The slide shafts are slidably matched with the first guiding grooves. The sliding trajectory of the slide shafts along the first guiding grooves is the first preset trajectory; during the rotation of the auxiliary board, the positions of the slide shafts in the first guiding grooves are unique.

[0009] With such a setting, the movement trajectory of the main board can be ensured to be unique, and further, the movement trajectory of the main board can be ensured to be uniform, smooth and stable.

[0010] Further, the first guiding grooves are arc-shaped grooves, and the arc-shaped grooves can ensure the smooth and stable movement of the main board.

[0011] Further, the auxiliary board is provided with second guiding grooves. One end of the slide shaft is slidably matched with the first guiding groove, and the other end is slidably matched with the second guiding groove; the sliding trajectory of the slide shaft along the second guiding groove is the second preset trajectory. It has the advantages of simple structure and low manufacturing cost.

[0012] Further, the sliding trajectory of the main board along the width direction of the auxiliary board is the second preset trajectory. With such a setting, it has the advantages of simple structure and low manufacturing cost.

[0013] Further, slide shaft supports are fixedly arranged on the left and right sides of the main board. The slide shafts are installed on the slide shaft supports; the setting of the slide shaft supports can make the design of the main board thinner and lighter, and is conducive to the disassembly and assembly of the slide shafts.

[0014] Further, the slide shaft includes an outer rotating shaft and an inner rotating shaft that are coaxially and fixedly connected. The outer rotating shaft is slidably connected with the first guiding groove, and the inner rotating shaft is slidably connected with the second guiding groove. With such a setting, the slide shaft can be conveniently slidably matched with the first guiding groove and the second guiding groove at the same time; not only the processing technology of the slide shaft is simplified, but also the disassembly and assembly efficiency of the slide shaft can be improved.

[0015] Further, one of the main board and the secondary board is provided with a slide rail, and the other is provided with a slider slidably connected to the slide rail, and the slide rail extends along the width direction of the secondary board. The arrangement of the slide rail and the slider can define the sliding direction of the main board.

[0016] Further, the secondary board is provided with a first chute; the main board is provided with a first slider, and the first slider is slidably engaged with the first chute and can slide in the first chute along the width direction of the secondary board. With such an arrangement, the sliding direction of the main board on the secondary board can be defined.

[0017] Further, the width of the notch of the first chute is smaller than the width of the end of the first slider, and the structure is simple. With such an arrangement, the up-and-down position of the main board relative to the secondary board can be defined, and further, the sliding direction of the main board on the secondary board can be ensured.

[0018] Further, the secondary board at least includes a horizontal board arranged in parallel with the main board and vertical boards fixed to the left and right sides of the horizontal board. The second guiding groove is arranged on the vertical board, and a driving shaft for drivingly connecting a driving device is fixedly arranged on the vertical board. The driving shaft is used for rotatably connecting with the frame body; the first chute is arranged on the horizontal board; sliding shaft supports are fixedly arranged on the left and right sides of the main board, and the sliding shafts are installed on the sliding shaft supports. The arrangement of the horizontal board facilitates the mating connection with the main board, and the arrangement of the vertical board is conducive to arranging the driving shaft.

[0019] Further, the main board or the horizontal board is provided with a convex rib, and the convex rib extends along the width direction of the horizontal board. With such an arrangement, the contact area between the main board and the horizontal board can be reduced, and further, the friction between the two can be reduced, making the sliding of the main board smoother.

[0020] The second object of the present invention is to provide an air conditioner to solve the technical problem that the rotation angle of the air-conditioning air deflector is limited and large-angle downward air supply cannot be achieved.

[0021] The air conditioner provided by the present invention includes a frame body, a motor, and the above-mentioned air deflector structure. The air deflector structure is installed at the air outlet of the frame body, and the motor is installed on the frame body and is drivingly connected to the secondary board to drive the secondary board to rotate. The beneficial effects of this air conditioner are the same as those of the above-mentioned guiding door structure, so they will not be elaborated here.

[0022] Further, the frame body includes a base and a middle frame fixedly connected to each other. The first guiding groove is located on the base or the middle frame, which has the advantage of simple structure. Description of the Drawings

[0063] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is provided with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0064] In the air deflector structure of an existing air conditioner, the main board is fixedly connected to the auxiliary board. In the initial position state, the main board closes the air outlet to prevent dust from entering the interior of the air conditioner in the standby state; in the use state, since the upper edge of the air outlet has a limiting effect on the upper edge of the main board, the auxiliary board cannot rotate upward and can only rotate downward to open the air deflector. Therefore, the adjustment of the upper and lower air guiding angles and the air supply distance of the main board are limited.

[0065] The air deflector structure provided by the embodiment of the present invention enables the main board 200 to be slidably engaged with the auxiliary board 300 and the frame 100 at the same time. The two sliding trajectories are fitted so that the main board 200 can rotate upward with the auxiliary board 300 and can also rotate downward with the auxiliary board 300. At the same time, during the rotation with the auxiliary board 300, it slides and extends outward on the auxiliary board 300, increasing the air supply distance, thereby realizing large-angle and long-distance air supply of the main board 200. For the specific structure and movement principle of the air deflector structure in the embodiment of the present invention, see the following analysis, taking the air deflector structure located at the air outlet 102 of the wall-mounted air conditioner frame 100 as an example.

[0066] The embodiment of the present invention provides an air deflector structure, as Figure 1a 、 Figure 1b 、 Figure 1c shown, this air deflector structure is arranged at the position of the air outlet 102 of the air conditioner frame 100, and includes a main board 200 and an auxiliary board 300; wherein, the auxiliary board 300 is rotatably connected to the frame 100, and under the driving action of the driving device, the auxiliary board 300 can rotate relative to the frame 100; the left and right sides of the main board 200 are slidably connected to the frame 100 and can slide on the frame 100 along a first preset trajectory, and the main board 200 is slidably connected to the auxiliary board 300 and can slide on the auxiliary board 300 along a second preset trajectory. During the process of the main board 200 opening the air outlet 102, the main board rotates with the auxiliary board 300 and slides outward on the auxiliary board 300 along the second preset trajectory under the limiting action of the first preset trajectory.

[0067] Figure 2a is a certain position state during the downward rotation of the auxiliary board 300 from the Figure 1a initial position, Figure 3a is the limit position state in this rotation direction. It can be known from the comparative analysis in the figure that during the downward rotation of the auxiliary board 300, the main board 200 not only rotates with the auxiliary board 300 to realize the downward adjustment of the air outlet angle, but also slides outward on the auxiliary board 300, that is, the main board 200 extends outward on the auxiliary board 300, increasing the air supply distance.

[0068] Figure 2a’ is a certain position state during the upward rotation of the auxiliary board 300 from the Figure 1a initial position, Figure 3a’It is the extreme position state of the rotation direction. From the comparative analysis in the figure, it can be seen that during the upward rotation of the sub-plate 300, the main plate not only rotates with the sub-plate 300 to adjust the air outlet angle upward, but also the main plate 200 slides outward on the sub-plate 300, that is, the main plate 200 extends outward on the sub-plate 300 to increase the air supply distance.

[0069] That is to say, assuming that the main board 200 initially closes the air outlet 102. When the main board 200 swings upward to open the air outlet 102, the sub-board 300 rotates upward. In addition to rotating with the sub-board 300, the main board 200 slides relative to the frame 100 and the sub-board 300 at the same time, that is, the movement trajectory of the main board 200 relative to the frame 100 is the first preset trajectory, and under the limitation of the first preset trajectory, the main board 200 slides outward on the sub-board 300 along the second preset trajectory, thereby releasing the upper edge of the main board 200 and the frame 100. The interference limitation of the upper edge of the air outlet 102 can realize the upward rotation of the sub-plate 300 until it reaches the extreme position state in the rotation direction, at which time the main board 200 reaches the maximum swing angle upward; when the main board 200 swings downward to open the air outlet 102, the main board 200 rotates with the sub-plate 300, and the main board 200 slides relative to the frame 100 and the sub-plate 300 at the same time, that is, the main board 200 slides outward on the sub-plate 300 along the second preset track under the limiting effect of the first preset track, thereby releasing the interference limitation of the lower edge of the main board 200 and the lower edge of the air outlet 102 of the frame 100, and then the sub-plate 300 can be rotated downward until it reaches the extreme position state in the rotation direction, at which time the main board 200 reaches the maximum swing angle downward. Since the main board 200 slides outward on the sub-plate 300 in the process of opening the air outlet 102, the air supply distance is increased. Thus, large-angle and long-distance air supply is achieved.

[0070] In short, during the rotation of the sub-panel 300, the main board 200 is limited by the first preset track and the second preset track at the same time, and the first preset track and the second preset track are fitted to form the motion track of the main board 200. The motion track of the main board 200 can not only rotate upward and downward with the sub-panel 300 to achieve different angles of swing, but also slide outward on the sub-panel 300 to achieve long-distance air supply.

[0071] In the embodiment of the present invention, Figure 4a , Figure 4b , Figure 4c The sliding connection structure between the main board 200 and the sub-board 300 is shown. Figure 5a , Figure 5b , Figure 5c 6a, 6b show the specific structure of the main board 200. Figure 6b , Figure 6c The specific structure of the sub-board 300 is shown. Figure 7a ,Figure 7b , Figure 8a , Figure 8b shows the specific structure of the housing 100, which is described as follows.

[0072] In the embodiment of the present invention, as Figure 7a , Figure 7b , Figure 8a , Figure 8b shown, on the left and right sides of the air outlet 102 of the housing 100, first guide grooves 101 are symmetrically arranged; as Figure 5a , Figure 5b shown, on the left and right sides of the main board 200, sliding shafts 201 are arranged. The sliding shafts 201 are in sliding fit with the first guide grooves 102, and the sliding track of the sliding shafts 201 along the first guide grooves 101 is the first preset track; during the rotation of the auxiliary board 300, the positions of the sliding shafts 201 in the first guide grooves 101 are unique. With such a setting, it can be ensured that the movement track of the main board 200 is unique, and further, the movement track of the main board 200 can be ensured to be uniform, smooth and stable.

[0073] It should be noted that in this embodiment, during the rotation of the auxiliary board 300, the fact that the positions of the sliding shafts 201 in the first guide grooves 101 are unique means that the rotation angle of the auxiliary board 300 corresponds one-to-one to the sliding positions of the sliding shafts 201 in the first guide grooves 101.

[0074] Specifically, as Figure 7a , Figure 7b , Figure 8a , Figure 8b shown, the first guide grooves 101 are arc-shaped grooves, that is, the first preset track is an arc-shaped movement track along the arc-shaped grooves, and the arc-shaped movement track can ensure the smooth and stable movement of the main board 200.

[0075] It should be noted that the sliding connection between the main board 200 and the housing 100 is realized by the sliding fit between the sliding shafts 201 and the first guide grooves 100. The structure is simple, the manufacturing cost is low, and it is easy to disassemble. In addition to this sliding connection method, other sliding connection methods can also be adopted. For example, the first guide grooves 101 are arranged on the main board 200, and the sliding shafts 201 are arranged on the housing 100 (not shown in the figure); or, a guide block and a guide rail are arranged between the main board 200 and the housing 100, and the guide block can move along the first preset track under the guiding action of the guide rail (not shown in the figure); these two sliding connection structures are also within the scope of protection required by the present invention.

[0076] In the embodiment of the present invention, as Figure 6a , Figure 6b , Figure 6cAs shown in the figure, the auxiliary board 300 is provided with a second guiding groove 302. One end of the sliding shaft 201 is slidably engaged with the first guiding groove 101, and the other end is slidably engaged with the second guiding groove 302; the sliding track of the sliding shaft 201 along the second guiding groove 302 is the second preset track. With such a setting, during the rotation of the auxiliary board 300, the sliding shaft 201 slides in the first guiding groove 101 and the second guiding groove 302 at the same time, thereby driving the main board 200 to slide on the auxiliary board 300 while rotating with the auxiliary board 300, thus realizing the up-and-down angular swing of the main board 200 and increasing the air supply distance, and having the advantages of simple structure and low manufacturing cost.

[0077] Specifically, as Figure 6a , Figure 6b , Figure 6c shown, the sliding track of the main board 200 along the width direction of the auxiliary board 300 is the second preset track. It can be seen from the figure that the main board 200 slides outward on the auxiliary board 300 along the width direction of the auxiliary board 300, thereby increasing the air supply distance, and further realizing long-distance air supply, and having the advantages of simple structure and low manufacturing cost. It should be noted that the second preset track in the embodiment of the present invention along the width direction of the auxiliary board 300 can be a straight line or an arc; in addition, the second preset track in the embodiment of the present invention is not limited to the width direction of the auxiliary board 300. For example, the second preset track can be slightly inclined to the width direction of the auxiliary board 300, as long as it can make the main board 200 slide on the auxiliary board 300 to increase the air supply distance, it is within the scope of protection of the present invention.

[0078] It should be noted that the sliding connection between the main board 200 and the auxiliary board 300 is realized through the sliding connection between the sliding shaft 201 and the second guiding groove 302, with a simple structure, low manufacturing cost, and easy disassembly. At the same time, the sliding shaft 201 can also take into account the realization of the above-mentioned sliding connection between the main board 200 and the frame 100. It can be seen that the same function can be realized with fewer components, simplifying the structure.

[0079] In the embodiment of the present invention, as Figure 5a , Figure 5b shown, sliding shaft supports 202 are arranged on the left and right sides of the main board 200, and the sliding shaft 201 is installed on the sliding shaft supports 202. Among them, the sliding shaft 201 can be fixed on the sliding shaft supports 202, and the sliding shaft 201 can also be rotatably connected to the sliding shaft supports 202, that is, the sliding shaft 201 can also be set to rotate relative to the sliding shaft supports 202. By arranging the sliding shaft supports 202 specifically for installing the sliding shaft 201 on both sides of the main board 200, the main board 200 can be designed to be thinner and lighter, and the sliding shaft 201 can be used for disassembly and assembly.

[0080] Specifically, as Figure 5a , Figure 5bAs shown, the sliding shaft 201 includes an outer rotating shaft 2011 and an inner rotating shaft 2012 that are coaxial and fixedly connected. The outer rotating shaft 2011 is used for sliding cooperation with the first guiding groove 101, and the inner rotating shaft 2012 is used for sliding cooperation with the second guiding groove 302. That is, the sliding shaft 201 can conveniently achieve sliding cooperation with both the first guiding groove 101 and the second guiding groove 302 simultaneously. The sliding shaft 201 can be set as a coaxial stepped rotating shaft. Among them, the diameter of the middle part fixed to the sliding shaft 202 is the largest, and the diameters of the outer rotating shaft 2011 and the inner rotating shaft 2012 on both sides are smaller. Such a setting not only simplifies the processing technology of the sliding shaft 201 but also can improve the disassembly and assembly efficiency of the sliding shaft 201.

[0081] It should be noted that, as Figure 4a 、 Figure 4b shown, the outer rotating shaft 2011 is used for sliding cooperation with the first guiding groove 101. That is, the outer rotating shaft 2012 can slide within the first guiding groove 101 to enable the main board 200 to slide on the frame body 100. At this time, the sliding trajectory of the outer rotating shaft 2012 within the first guiding groove 101 of the frame body 100 is the first preset trajectory; the inner rotating shaft 2012 is in sliding cooperation with the second guiding groove 302. That is, the inner rotating shaft 2012 can slide within the second guiding groove 302 to enable the main board 200 to slide on the auxiliary board 300. At this time, the sliding trajectory of the inner rotating shaft 2011 within the second guiding groove 302 of the auxiliary board 300 is the second preset trajectory.

[0082] In the embodiment of the present invention, as Figure 6a 、 Figure 6c shown, the auxiliary board 300 is provided with a first sliding groove 305; as Figure 5a 、 Figure 5c shown, the main board 200 is provided with a first sliding block 204; as Figure 4a 、 Figure 4c shown, the first sliding block 204 is in sliding cooperation with the first sliding groove 305 and can slide within the first sliding groove 305 along the width direction of the auxiliary board 300. That is, the first sliding block 204 on the main board 200 is in sliding cooperation with the first sliding groove 305, and the first sliding block 204 can slide within the first sliding groove 305. Such a setting can define the sliding direction of the main board 200 on the auxiliary board 300.

[0083] Specifically, in this embodiment, the width of the notch of the first sliding groove 305 is smaller than the width of the end of the first sliding block 204 to limit the first sliding block 204 to slide within the corresponding space of the first sliding groove 305. As Figure 5c shown, the cross-sectional shape of the first sliding block 204 is an "I"-shaped structure. As Figure 4cAs shown, the "I"-shaped cross-section chute structure can clamp the two side walls of the first chute 305 in the slots on both sides of the first slider 204, thereby realizing the upper and lower position limitation of the main board 200 relative to the sub-board 300, and further ensuring the sliding direction of the main board 200 on the sub-board 300. In addition to this structure, the first chute 305 can also be set as a dovetail groove, and the end of the first slider 204 corresponds to this dovetail groove. The cross-section of the first chute 305 can also be arc-shaped, etc., as long as the first slider 204 can be limited to slide in the corresponding space of the first chute 305, it is within the scope of protection required by the present invention.

[0084] It should be noted that the sliding fit between the first slider 204 on the main board 200 and the first chute 305 on the sub-board 300 can be realized by other sliding connection methods to achieve the same limiting function. For example, the main board 200 is provided with a second chute, the sub-board is provided with a second slider, and the second slider is slidably fitted with the second chute and can slide along the width direction of the sub-board 300 in the second chute; or, a slide rail and a slider are provided between the main board 200 and the sub-board 300, the slide rail extends along the width direction of the sub-board 300, and the slider can move along the second preset track (the width direction of the sub-board 300) under the guiding action of the slide rail (not shown in the figure); these two sliding connection structures are also within the scope of protection required by the present invention, and have the advantages of simple structure and low processing cost.

[0085] In the embodiment of the present invention, as Figure 6a , Figure 6b , Figure 6c shown, the sub-board 300 includes a cross board 303 and a vertical board 304. The cross board 303 is arranged parallel to the main board 200. There are at least two vertical boards 304, which are respectively fixedly connected to the left and right sides of the cross board 303 in parallel. The second guiding groove 302 is arranged on the vertical board 304 and extends along the width direction of the cross board 303. A driving shaft 301 is fixedly arranged on the vertical board 304, and this driving shaft 301 is used for driving connection with a driving device (for example, the motor 400) to drive the sub-board 300 to rotate. As Figure 6c shown, the first chute 305 is arranged on the cross board 303 and extends along the width direction of the cross board 303. Please continue to see Figure 4a , Figure 4b , the sliding shaft support 202 is a plate-like structure and is parallel to the vertical board 304. It should be noted that when the cross board 202 is relatively long, as Figure 6a shown, multiple vertical boards 304 can be arranged and are arranged in parallel. A connecting board parallel to the cross board 303 is fixedly connected above the vertical boards 304 to ensure the strength of the entire sub-board 300. The arrangement of the cross board 303 is convenient for the cooperation and connection with the main board 200, and the arrangement of the vertical board 304 is beneficial to the arrangement of the driving shaft 301.

[0086] Please continue to refer to Figure 5a ,Figure 5b In the embodiment of the present invention, a convex rib 203 is provided on the main board 200, and the length direction of the convex rib 203 extends along the width direction of the main board 200. It should be noted that in this embodiment, the width directions of the main board 200 and the auxiliary board 300 are the same. With the arrangement of the convex rib 203 on the main board 203, when the main board 200 slides relative to the cross board 303, the convex rib 203 abuts against the cross board 303. Thus, it can be seen that during the sliding process of the main board 200, the contact area between the main board 200 and the cross board 303 is reduced, thereby reducing the friction force between the two, making the sliding of the main board 200 relative to the cross board 303 smoother. The convex rib 203 can also be provided on the cross board 303, and the convex rib 203 abuts against the main board 200, further reducing the friction force when the main board 200 and the cross board 303 slide relative to each other, making the sliding of the main board 200 relative to the cross board 303 smoother.

[0087] For a clearer description of the movement principle of the main board 200, please refer to Figure 9a 、 Figure 9b 、 Figure 9b’ ,wherein, Figure 9a shows the initial position state of the main board 200 and the auxiliary board 300 relative to the frame 100. Figure 9b shows the state where the auxiliary board 300 rotates to the limit position along the F' direction. It can be seen from this figure that the main board 200 slides downward relative to the auxiliary board 300, increasing the air supply distance in this rotation direction; Figure 9b’ shows the state where the auxiliary board 300 rotates to the limit position along the F direction. It can be seen from this figure that the main board slides upward relative to the auxiliary board 300, increasing the air supply distance in this rotation direction; that is to say, the main board 200 in the air deflector structure of the embodiment of the present invention can rotate forward or backward along with the auxiliary board 300, and can increase the air supply distance, thereby realizing large-angle and long-distance air supply.

[0088] To further illustrate the principle of the movement trajectory of the main board 200, please combine Figure 10a 、 Figure 10b 、 Figure 10b’ 、 Figure 10c 、 Figure 10c’ ,where L is the length of the second guide groove 302, and R is the vertical distance from the drive shaft 301 to the second guide groove 302. Figure 10a is the initial position state. At this time, the sliding shaft 201 is located at a certain position in the middle of the second guide groove 302, and the sliding shaft 201 is located at a certain position in the middle of the first guide groove 101. At this time, the main board 200 closes the air outlet 102 (not shown in the figure); Figure 10b is a certain position state during the rotation of the auxiliary board 300 in the F direction. At this time, the sliding shaft 201 slides to the corresponding position in the first guide groove 101 and the second guide groove 302 at the same time, and at this time, the main board 200 is in an open state (not shown in the figure); Figure 10cThe auxiliary plate 300 rotates to the limit position in the F direction, and the sliding shaft 201 slides to the limit positions of the first guide groove 101 and the second guide groove 302 shown in the figure at the same time; Figure 10b’ The second position of the auxiliary board 300 is a state in which the auxiliary board 300 rotates in the F' direction. At this time, the sliding shaft 201 slides in the first guide groove 101 and the second guide groove 302 to the position shown in the corresponding guide groove. At this time, the main board 200 is in an open state (not shown in the figure). The opening direction of the main board 200 is opposite to the opening direction of the above main board 200, that is, the main board 200 can be guided upward or downward respectively. Figure 10c’ The auxiliary plate 300 rotates to the limit position in the F' direction, and the slide shaft 201 slides to the limit positions of the first guide groove 102 and the second guide groove 302 shown in the figure at the same time. In the motion trajectory fitting process, the position of the slide shaft 201 is unique.

[0089] From the above analysis, it can be known that the motion trajectory of the main board 200 is determined by both the first guide groove 101 and the second guide groove 302, that is, during the rotation of the main board 200 along with the sub-board 300, the corresponding working motion state is realized under the joint limiting effect of the first guide groove 101 and the second guide groove 302. From another perspective, during the rotation of the sub-board 300, the first guide groove 101 plays a role in driving the sliding shaft 201 to slide along the second guide groove 302. Therefore, in the embodiment of the present invention, there is no need to specially set a driving device for driving the main board 200 to slide along the sub-board 300 (cross board 303), which simplifies the structure and reduces the manufacturing and installation costs.

[0090] The embodiment of the present invention further provides an air conditioner, such as Figure 1a As shown, the air conditioner comprises a frame 100, a motor 400 and the above-mentioned air guide door structure, wherein the air guide door structure is installed at the air outlet 102 of the frame 100, and the motor 400 is installed on the frame 100 and is transmission-connected with the sub-plate 300 to drive the sub-plate 300 to rotate. The air conditioner has the same beneficial effects as the above-mentioned guide door structure, so it is not repeated here.

[0091] Specifically, the frame 100 includes a base 103 and a middle frame 104, which are fixedly connected. Figure 7a , Figure 7b As shown, the first guide groove 101 can be provided on the middle frame 104; Figure 8a , Figure 8b As shown, the first guide groove 102 can also be arranged on the base 103, which has the advantage of simple structure.

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.
