[0034] 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.

[0035] The embodiment of the present invention provides a filter screen automatic flipping structure, combined with Figure 1 and Figure 2 As shown, it includes a shell 1, a base frame 2 and a filter 3. An air inlet is arranged above the shell 1, and the filter 3 is installed on the base frame 2. The base frame 2 is installed above the shell 1 and covers the air inlet. A moving component 4 is arranged on one side of the shell 1. One end of the base frame 2 is connected to the moving component 4, and the other end of the base frame 2 is connected to the other side of the shell 1. The moving component 4 is used to flip the base frame 2 and then push out the filter 3, or push the filter 3 in and then flip the base frame 2.

[0036] The automatic flipping structure of the filter designed in this embodiment is provided with a base frame 2 at the air inlet above the shell 1, and the filter 3 is installed on the base frame 2, and the filter 3 currently arranged on the front side of the shell 1 is arranged above the shell 1, thereby effectively reducing the volume occupied by the filter 3, and the structure of the shell 1 can be greatly adjusted to change the appearance of the air conditioner. At the same time, a motion component 4 is provided on one side of the shell 1. The base frame 2 is flipped by the motion component 4 and then the filter 3 is pushed out, or the filter 3 is pushed in and then the base frame 2 is flipped, thereby realizing the automatic disassembly / installation process of the filter 3, and facilitating the user to disassemble and clean the filter 3.

[0037] Combination Figure 3 As shown, the filter 3 includes a filter portion 31 and a mounting portion 32. The filter portion 31 is a rectangular frame structure. A plurality of brackets are provided on the filter portion 31 for supporting the filter mounted on the frame. A mounting portion 32 is provided on one side edge of the filter portion 31. The mounting portion 32 is a long strip structure, and its thickness is greater than that of the filter portion 31, wherein the thickness is the distance in the Y-axis direction, thereby ensuring the comfort of the user's grip.

[0038] Combination Figure 4 As shown, a mounting groove 21 is provided on the base frame 2. Specifically, the base frame 2 includes a frame around and a plurality of transverse bars in the middle, wherein the direction of the transverse bars is the same as the Z axis, and the plurality of transverse bars are evenly arranged on the frame. Further, the plurality of transverse bars are arranged in two rows on the frame, wherein the plurality of bars arranged above are an upper bar frame group, and the plurality of bars arranged below are a lower bar frame group. There is a gap between the upper bar frame group and the lower bar frame group in the vertical direction, that is, in the Y-axis direction, and the gap is the mounting groove 21. The filter portion 31 is inserted into the mounting groove 21 along the plane where the mounting groove 21 is located, wherein the plane where the mounting groove 21 is located is parallel to the upper surface or the lower surface of the base frame 2. The filter screen 3 is installed between the upper bar frame group and the lower bar frame group, and is fixed by the upper bar frame group and the lower bar frame group. After the filter screen 3 is installed on the base frame 2, the mounting portion 32 is placed outside the mounting groove 21, as shown in FIG. Figure 5 As shown, the thickness of the mounting portion 32 is greater than the distance between the upper and lower rack groups, preventing the movement component 4 from malfunctioning and causing the entire filter 3 to enter the mounting groove 21, thereby damaging the base frame 2 and the filter 3. Preferably, the thickness of the mounting portion 32 is greater than the distance between the upper and lower surfaces of the base frame 2, so that the user can quickly grab the filter 3 and quickly pull out the filter 3. It is worth noting that the number of racks in the upper and lower rack groups is not necessarily the same, and the distribution positions are not necessarily corresponding. In this embodiment, the lower rack group is set at a position close to the front side, and the upper rack group is set at a position close to the rear side, and only a portion of the projections of the two on the plane where the XZ axis is located overlap.

[0039] Preferably, a fixing bar pointing in the same direction as the X-axis is provided between the upper frame group and the lower frame group, and the fixing bar divides the mounting groove 21 on the base frame 2 into two, that is, two filter screens 3 are provided on the base frame 2, and a large filter screen 3 is divided into two small filter screens 3 for separate installation, thereby improving the structural strength of the filter screen 3 and the base frame 2 and facilitating the installation of the filter screen 3.

[0040] Connecting shafts are arranged on both sides of the base frame 2, the left side of the base frame 2 is connected to the moving component 4 on the left side of the shell 1, and the right side of the base frame 2 is point-connected to the right side of the shell 1, wherein the point connection is a connection between an axis and a hole, that is, a cylindrical shaft or a cylindrical hole is arranged on the right side of the base frame 2, and a matching cylindrical hole or cylindrical shaft is arranged on the right side of the shell 1, so that after the right side of the base frame 2 is installed on the right side of the shell 1, the base frame 2 can rotate relative to its installation position with the shell 1 under the drive of the moving component 4. In this embodiment, a column shaft 22 is arranged on the right side of the base frame 2, and a column hole matching it is arranged on the right side of the shell 1. The column shaft 22 matches the column hole and the two can rotate with each other. Furthermore, a shaft sleeve is also arranged between the column shaft 22 and the column hole. The shaft sleeve can effectively reduce the wear between the column shaft 22 and the column hole, thereby reducing the cost of parts replacement.

[0041] Combination Figure 7-9As shown, the motion assembly 4 includes a motor 41, a driving gear 43 and a crankshaft 42. The motor is used to provide power. The driving gear 43 is connected to the output shaft of the motor 41 through a flat position. The driving gear 43 is meshed with the crankshaft 42 through gears. In this embodiment, the crankshaft 42 includes a shaft 421. A shaft seat 23 matching the shaft 421 is provided on the left side of the base 2. A hole is provided in the shaft seat 23. The shaft 421 of the crankshaft 42 is inserted into the hole of the shaft seat 23 for fixing. The shaft 421 can be set as a hexagonal column, and the hole can be set as a hexagonal hole body matching the shaft 421, so as to ensure the relative fixation of the shaft 421 and the hole. In other embodiments, a hole can be provided on the crankshaft 42, and a shaft can be provided on the left side of the base 2. The two are also matched in the above manner, so as to ensure that the power of the motor 41 can be effectively transmitted to the base 2 through the crankshaft 42, and the base 2 is driven to flip.

[0042] The motion component 4 also includes a driven gear 44 and a box body 45. The crankshaft 42, the driving gear 43 and the driven gear 44 are all arranged in the box body 45. The box body 45 is a rectangular structure with an installation cavity arranged inside. The crankshaft 42, the driving gear 43 and the driven gear 44 are arranged in the installation cavity. A motor 41 is arranged on one side of the outer side of the box body 45. The motor 41 is fixed to the box body 45 by screws. A first through hole is arranged on the left side of the box body 45. The power output shaft of the motor 41 passes through the first through hole on the side of the box body 45 and enters the installation cavity in the box body 45, and is connected to the driving gear 43. Specifically, the driving gear 43 is sleeved on the output shaft of the motor 41. The output shaft of the motor 41 is a flat cylindrical structure. A flat hole matching the motor output shaft is arranged in the middle of the driving gear 43. After the two are installed, their positions are relatively fixed, and the motor 41 drives the driving gear 43 to rotate.

[0043] The driving gear 43 includes a first tooth portion 431, a second tooth portion 432 and a first toothless portion 433, wherein the first tooth portion 431 is arranged on one side, and the second tooth portion 432 and the first toothless portion 433 are arranged on the same side. The length of the first tooth portion 431 is equal to the length of the driving gear 43, wherein the length refers to the distance in the Z-axis direction, and the length of the second tooth portion 432 plus the first toothless portion 433 is equal to the length of the driving gear 43.

[0044] The crankshaft 42 includes a shaft portion 421, a third tooth portion 422, and a second toothless portion 423. The shaft portion 421 is arranged at the center of the crankshaft 42. A second through hole is also arranged on the right side of the box body 45. The shaft portion 421 passes through the second through hole, extends out of the box body 45, and is connected to the base frame 2. The third tooth portion 422 is arranged on one side of the crankshaft 42, and the second toothless portion 423 is arranged on the other side of the crankshaft 42. The third tooth portion 422 is only meshed with the first tooth portion 431, wherein the length of the first toothless portion 433 is greater than or equal to the length of the third tooth portion 422, so as to prevent the third tooth portion 422 from meshing with the second tooth portion 432. A protrusion 424 is provided at the junction of the second toothless portion 423 and the third toothed portion 422, and the protrusion 424 matches the first toothless portion 433. When the crankshaft 42 rotates to the point where it is no longer engaged with the first toothed portion 431 of the driving gear 43, the protrusion 424 abuts against the first toothless portion 433, thereby maintaining the stability of the crankshaft 42 and preventing the base frame 2 connected to the crankshaft 42 from deflecting.

[0045] The driven gear 44 meshes with the driving gear 43, and the driven gear 44 includes a fourth tooth portion 441, which covers the arc surface of the driven gear 44, and the length of the fourth tooth portion 441 is greater than the first tooth portion 431, and the fourth tooth portion 441 can mesh with both the first tooth portion 431 and the second tooth portion 432. A third through hole is also provided on the right side of the box body 45, and the diameter of the third through hole is slightly larger than that of the driven gear 44. The driven gear 44 extends from the third through hole and is connected to the filter 3 to push the displacement of the filter 3. Specifically, a toothed structure 33 is provided at a corresponding position of the mounting portion 32 of the filter 3, and the toothed structure meshes with the fourth tooth portion 441 on the driven gear 44, thereby pushing the filter 3 to move outward, or pulling the filter 3 to move inward.

[0046] like Fig.10 As shown in FIG. 1 , when the filter 3 is removed, the motor 41 drives the driving gear 43 to rotate counterclockwise. Under the action of gear meshing, the driving gear 43 drives the crankshaft 42 to rotate clockwise, thereby driving the base frame 2 and the filter 3 to rotate clockwise. Since the driving gear 43 and the crankshaft 42 are both incomplete gears, that is, the driving gear 43 no longer meshes with the crankshaft 42 after rotating to a certain angle, as shown in FIG. Fig.11As shown, after running to a certain angle, the third tooth portion 422 of the crankshaft 42 and the first tooth portion 431 of the driving gear 43 do not mesh, and the protrusion 424 of the crankshaft 42 abuts against the first toothless portion 433 of the driving gear 43. The base frame 2 maintains the angle unchanged, that is, the driving gear 43 continues to rotate counterclockwise, but the crankshaft 42 stops rotating. In the process from the start of the movement to the time when the crankshaft 42 stops moving, the driven gear 44 is always in meshing with the driving gear 43 and rotates clockwise. However, before the base frame 2 reaches a certain calibration angle, the driven gear 44 does not mesh with the toothed structure 33 on the filter screen 3. When the base frame 2 and the filter screen 3 rotate to a certain calibration angle, that is, the crankshaft 42 stops rotating, the driven gear 44 meshes with the toothed structure 33 on the filter screen 3, as shown in FIG. Fig.12 As shown, the driven gear 44 starts to drive the filter screen 3 to move obliquely downward and stops after moving to a certain position, that is, the driving gear 43 rotates one circle, so that the motor 41 stops moving before the first tooth portion 431 interferes with the protrusion 424.

[0047] The closed state can be released by resetting in the above order in reverse, so it will not be repeated here.

[0048] In this embodiment, the calibrated rotation angle of the base frame 2 is less than or equal to 90 degrees. If the rotation range of the filter 3 is greater than 90 degrees, the reserved space required in the shell 1 will be so large that it will affect the arrangement of parts inside the air conditioner.

[0049] In this embodiment, an air inlet grille 11 is provided at the air inlet. The air inlet grille 11 is a hollow frame structure. The air inlet grille 11 is used to strengthen the overall structural strength of the housing 1. At the same time, the hollow structure on the air inlet grille 11 can effectively intake air. The air inlet grille 11 is arranged below the base frame 2, that is, after the filter base frame 2 is installed on the housing 1, the base frame 2 covers the air inlet grille 11, and at the same time, the filter net 3 on the base frame 2 completely covers the air inlet grille 11, and the air entering from the air inlet grille 11 is first filtered by the filter net. Among them, the rotation axis of the base frame 2 is located at the front side of the air inlet grille 11, that is, the air inlet grille 11 is arranged at the rear side of the rotation axis of the base frame 2, so as to prevent the air inlet grille 11 from interfering with the front side of the base frame 2, so that the front side of the base frame 2 cannot rotate downward.

[0050] Furthermore, there is a height difference between the upper surface of the air inlet grille 11 and the plane where the upper surface of the shell 1 is located, and the height difference is greater than the distance between the upper and lower surfaces of the base frame 2, that is, a recessed area is formed between the upper surface of the air inlet grille 11 and the two sides of the shell 1, and the base frame 2 is installed in the recessed area. The upper surface of the base frame 2 does not exceed the upper surface of the shell 1, thereby ensuring the aesthetics of the structure of the shell 1.

[0051] Preferably, a rotating shaft 24 is provided in the middle of the base frame 2, and a buckle is provided at the corresponding position of the air inlet grille 11, wherein the buckle can be an eagle's beak structure, the rotating shaft 24 can be pressed into the buckle, and limited in a certain direction by the buckle, and the rotating shaft 24 can rotate in the buckle at the same time. The connection between the base frame 2 and the air inlet grille 11 effectively increases the installation strength of the base frame 2, and ensures the structural strength of the shell 1 to a certain extent.

[0052] In this embodiment, the base frame 2 rotates around the connection with the shell 1 under the drive of the motor 41, wherein the connection between the base frame 2 and the shell 1 is arranged at the front side of the shell. When the base frame 2 is disassembled, the front end of the base frame 2 moves downward and the rear end tilts upward under the drive of the motor 41, and the mounting portion 32 of the filter 3 faces downward, which is convenient for the user to grasp and draw downward.

[0053] like Figure 2 As shown, at least one supporting rib 12 is provided between the ends of the shell 1 located on both sides of the air inlet, wherein the supporting rib 12 is parallel to the rotation axis of the base frame 2, and the supporting rib 12 is located below the front side of the rotation axis, and at least one limiting rib 14 is provided between the front end of the air inlet grille 11 and the supporting rib 12, wherein the limiting rib 14 is inclined toward the front side and below, and the supporting rib 12 is provided below the air inlet for reinforcing the structural lightness of the front side of the shell 1, and further, reinforcing plates 13 extending downward are provided on the shell 1 on both sides of the air inlet, and both ends of a plurality of supporting ribs 12 are fixed on the reinforcing plates 13 on both sides of the shell 1 to increase the structural strength around the air inlet.

[0054] Another embodiment of the present invention provides an air conditioner, which includes the automatic filter flipping structure as described above.

[0055] The air conditioner designed in this embodiment is provided with a base frame 2 at the air inlet above the shell 1, and the filter 3 is installed on the base frame 2, and the filter 3 currently arranged on the front side of the shell 1 is arranged above the shell 1, thereby effectively reducing the volume occupied by the filter 3, and the structure of the shell 1 can be greatly adjusted to change the appearance of the air conditioner. At the same time, a motion component 4 is provided on one side of the shell 1. The base frame 2 is flipped by the motion component 4 and then the filter 3 is pushed out, or the filter 3 is pushed in and then the base frame 2 is flipped, thereby realizing the automatic disassembly / installation process of the filter 3, and facilitating the user to disassemble and clean the filter 3.

[0056] 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.
