[0003] Common ways to install filters include adding side plates or guide grooves to the unit, connecting the filter to the frame of the unit or embedding it at the edge of the frame. Although the purpose of filtering dust can be achieved, the addition of side plates makes the production cost higher, and the installation of guide grooves is limited by the installation space, making it difficult to load and unload the filter.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content

When the first connecting rod is parallel to the filter plate, the second connecting rod and the filter plate have a first angle, and the elastic member and the filter plate have a second angle, and the first angle is greater than the second angle.

[0009] Further, when the first connecting rod is parallel to the filter plate, the distance between the second connecting position and the filter plate and the distance between the fourth connecting position and the filter plate are both smaller than the distance between the sixth connecting position and the filter plate.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] According to an embodiment of the present invention, a filter assembly is provided. Figures 1 to 6 , including: a connecting piece 1, a filter plate 6 is connected to the connecting piece 1, and the connecting piece 1 is perpendicular to the filter plate 6; a fixing piece 2, the fixing piece 2 and the connecting piece 1 are arranged at intervals; a first connecting rod 3, a first connecting position 31 and a second connecting position 32 are arranged on the first connecting rod 3, the first connecting position 31 is hinged to the connecting piece 1, the second connecting position 32 is hinged to the fixing piece 2, and the first connecting position 31 and the second connecting position 32 are arranged at intervals; a second connecting rod 4, a third connecting position 41 and a fourth connecting position 42 are arranged on the second connecting rod 4, the third connecting position 41 is hinged to the connecting piece 1, the fourth connecting position 42 is hinged to the fixing piece 2, and the third connecting position 41 and the fourth connecting position 42 are arranged at intervals; the first connecting rod 3 and the second connecting rod 4 are arranged at intervals, the first connecting rod 3 is located between the filter plate 6 and the second connecting rod 4, and when the first connecting rod 3 and the second connecting rod 4 are rotated, the connecting piece 1 drives the filter plate 6 to rotate so that the filter plate 6 rotates around the fixing piece 2. The filter plate 6 is vertically connected to the connecting plate 1, and the two ends of the first connecting rod 3 and the second connecting rod 4 are hinged to the connecting plate 1 and the fixing plate 2 respectively. The fixing plate 2 is fixed to one side of the unit, and the first connecting rod 3 and the second connecting rod 4 drive the filter plate 6 on the connecting plate 1 to rotate, so that the filter plate 6 rotates around the fixing plate 2, thereby moving the filter plate 6 away from or close to the fixing plate 2. In the past, it was necessary to use side plates (such as Figure 7 as shown) or guide groove (as shown Figure 8 The filter plate is fixed on the housing of the air conditioner (as shown in the figure). If the internal parts need to be repaired, the filter plate needs to be removed or pulled out. This operation increases the loading and unloading steps and is time-consuming and labor-intensive. In the filter assembly of this embodiment, the filter plate 6 rotates relative to the housing where the fixing plate 2 is located, thereby opening the housing for easy inspection and maintenance of internal parts. Compared with the side plate and guide groove arrangement, the filter assembly of this embodiment is simple to disassemble, has a low production cost, and is also conducive to the internal inspection of the air conditioner. The filter assembly of this embodiment solves the technical problems of cumbersome loading and unloading operations and great difficulty in loading and unloading of the filter assembly of air-conditioning equipment in the related art.

[0032] See also Figure 1 and Figure 2In the filter assembly of the present embodiment, the distance between the first connection position 31 and the second connection position 32 is greater than the distance between the third connection position 41 and the fourth connection position 42, so that the filter plate 6 rotates relative to the third connection position 41 as the center. That is to say, when the first connecting rod 3 and the second connecting rod 4 rotate at the same time, the filter plate 6 moves relative to the fixed plate 2. Since the length of the first connecting rod 3 is greater than the second connecting rod 4, the moving trajectory of the filter plate 6 rotates with the third connection position 41 of the second connecting rod 4 as the center. This design not only allows the filter plate 6 to be displaced relative to the fixed plate 2, but also provides an operating space for loading and unloading the fixed plate 2; the filter plate 6 rotates with the third connection position 41 as the center, which is equivalent to opening and closing the filter plate 6 as a door. When the internal maintenance of the unit is carried out, the filter plate 6 is rotated to open it, and then the filter plate 6 is closed after completion. The filter assembly of the present embodiment can be opened and closed quickly, and is easy to operate. Even narrow passages do not affect the loading and unloading of the filter plate 6, and the scope of use is wide.

[0033] See also Figure 1 In the filter assembly of the present embodiment, the filter assembly further includes an elastic member 5, one end of the elastic member 5 is connected to the connecting plate 1 through the fifth connecting position 51, and the other end of the elastic member 5 is connected to the fixing plate 2 through the sixth connecting position 52. The elastic member 5 is located on the side of the connecting plate 1 away from the first connecting rod 3 and the second connecting rod 4. When the first connecting rod 3 is parallel to the filter plate 6, the second connecting rod 4 and the filter plate 6 have a first angle, and the elastic member 5 and the filter plate 6 have a second angle, and the first angle is greater than the second angle. The unit will generate slight vibration during operation. When the first connecting rod 3 is parallel to the filter plate 6 (at this time, the filter plate 6 is in a closed state relative to the unit housing), it is easy to cause the filter plate 6 to rotate, thereby opening the inside of the unit, reducing the filtering effect. In order to avoid the above situation, an elastic member 5 is provided in this embodiment. The elastic member 5 is a spring. One end of the spring is connected to the connecting plate 1 and the other end is connected to the fixing plate 2. The fifth connecting position 51 and the sixth connecting position 52 are provided so that the spring is in a stretched state when the first connecting rod 3 is parallel to the filter plate 6, and the tension of the spring is used to strengthen the connection between the connecting plate 1 and the fixing plate 2. When the first connecting rod 3 is parallel to the filter plate 6, the first angle between the second connecting rod 4 and the filter plate 6 is greater than the second angle between the spring and the filter plate 6, so that the tension of the spring is always maintained between the first connecting rod 3 and the second connecting rod 4. When the filter plate 6 starts to rotate away from the unit housing, the spring force in the stretched state gradually decreases until the filter plate 6 rotates to a certain angle, and the spring is reset. At this time, the filter plate 6 is fixed and has an angle with the unit housing, which is equivalent to opening the inside of the unit.

[0034] See also Figure 1 and Figure 2In the filter assembly of this embodiment, when the first connecting rod 3 is parallel to the filter plate 6, the distance between the second connecting position 32 and the filter plate 6 and the distance between the fourth connecting position 42 and the filter plate 6 are both smaller than the distance between the sixth connecting position 52 and the filter plate 6. When the filter plate 6 is in a closed state relative to the unit housing, the distance from the sixth connecting position 52 of the spring on the fixing plate 2 to the filter plate 6 is greater than the distance from the second connecting position 32 of the first connecting rod 3 and the fourth connecting position 42 of the second connecting rod 4 to the filter plate 6. This arrangement can increase the force of the spring on the connecting plate 1 and the fixing plate 2, so that the filter plate 6 can be stably attached to the unit housing, thereby achieving a filtering effect.

[0035] In the filter assembly of the present embodiment, the elastic member 5 is detachably connected to the connecting plate 1 so that the distance between the fifth connecting position 51 and the filter plate 6 can be adjusted. The sixth connecting position 52 is fixed, and the distance between the fifth connecting position 51 and the filter plate 6 determines the size of the angle between the spring and the filter plate 6, and the angle between the spring and the filter plate 6 determines the angle between the filter plate 6 and the unit housing when the spring is reset. The spring reset process is equivalent to drawing an arc from the second connecting rod 4 to the first connecting rod 3 with the sixth connecting position 52 as the center and the spring length as the radius. If the fifth connecting position 51 is closer to the third connecting position 41, the spring will eventually pull the filter plate 6 to stay near the third connecting position 41, and at this time, the angle between the filter plate 6 and the fixed plate 2 is large. If the fifth connecting position 51 is closer to the first connecting position 31, the spring will eventually pull the filter plate 6 to stay near the first connecting position 31, and at this time, the angle between the filter plate 6 and the fixed plate 2 is small. It can be seen that by adjusting the position of the fifth connecting position 51 on the connecting sheet 1 , the opening and closing angle of the filter plate 6 can be adjusted.

[0036] See also Figure 2 and Figure 3 In the filter assembly of this embodiment, the distance between the first connection position 31 and the filter plate 6 is L1, the distance between the third connection position 41 and the filter plate 6 is L2, and the distance between the fifth connection position 51 and the filter plate 6 is L3, wherein L1<L3<L2. That is, the distance L3 between the fifth connection position 51 and the filter plate 6 is greater than the distance L1 between the first connection position 31 and the filter plate 6, and is less than the distance L2 between the third connection position 41 and the filter plate 6, thereby determining the angle between the spring and the filter plate 6.

[0037] During the process of the filter plate 6 rotating around the fixing plate 2, the angles between the first connecting rod 3, the second connecting rod 4, the spring and the unit housing change. Figure 3As shown, taking the extension direction of the unit casing as a reference, the first connecting rod 3 and the selected reference include an angle γ, and the value range of γ is 0°<γ<90°. When the filter plate 6 rotates nearly 90° relative to the selected reference, the filter plate 6 is approximately parallel to the unit casing, so the angle between the first connecting rod 3 and the selected reference cannot exceed 90°; the second connecting rod 4 and the selected reference include an angle α, and the value range of α is 0°<α<γ+90°. The first connecting rod 3 can rotate relative to the second connecting rod 4. In order to prevent the first connecting rod 3 from rotating around the second connecting rod 4, the maximum value of α cannot exceed γ+90°; the spring and the selected reference include an angle β, and the value range of β is 0°<β<γ, so that the tension of the spring is between the first connecting rod 3 and the second connecting rod 4.

[0038] See also Figure 4 In order to more clearly understand the relationship between the connection points of the first connecting rod 3, the second connecting rod 4 and the spring and the connecting plate 1 and the fixing plate 2 respectively, the motion trajectory of each component is used for explanation. Assume that the distance from the first connection position 31 to the second connection position 32 is L4, the distance from the third connection position 41 to the fourth connection position 42 is L5, and L4 is greater than L5. If each component is connected singly, the running angle of the first connection position 31 on the first connecting rod 3 around the second connection position 32 is 360°, the movement angle of the third connection position 41 on the second connecting rod 4 around the fourth connection position 42 is 360°, and the movement angle of the fifth connection position 51 on the elastic member 5 around the sixth connection position 52 is 360°. That is to say, the motion trajectory of the first connecting rod 3 is on a circle with the second connection position 32 as the center and L4 as the radius, and the motion trajectory of the second connecting rod 4 is on a circle with the fourth connection position 42 as the center and L5 as the radius. During the overall movement, due to the mutual constraints between the various parts, the actual movement trajectory is only an arc trajectory on the circle, and the length of the elastic member 5 is in a state of continuous expansion and contraction. During a certain transient movement process, its movement trajectory is an arc segment with the sixth connecting position 52 as the center and the length of this transient elastic member as the center.

[0039] In order to improve the stability of the filter assembly, the stability of the starting position (the state of being closed with the unit housing) and the ending position (the final balanced state with the filter plate 6 opened and an angle with the unit housing) is provided by the self-supporting force of the elastic member 5. From the beginning of the unit being in the closed state to the state of the filter plate 6 being opened and finally staying at a certain angle, the elastic member 5 gradually decreases from the maximum tensile force until the mutual force with the first connecting rod 3 and the second connecting rod 4 is balanced, and the tensile force of the elastic member 5 is the minimum. Taking the sixth connection position 52 as the base point and the extension direction of the unit housing as the horizontal reference, the second connection position 32 is Figure 4 The vertical reference counterclockwise angle is θ1, θ1∈(-90°, 90°); the fourth connection position 42 is Figure 4The horizontal reference clockwise angle θ2, θ2∈(-90°, 180°), in order to meet the overall miniaturization and universal design, θ1∈(0°, 45°), θ2∈(0°, 45°) are preferably selected, and the minimum value within this range is the optimal value.

[0040] Since L4>L5, when the sum of L5 (i.e., the length of the second connecting rod 4) and the distance from the first connection position 31 to the third connection position 41 is greater than the sum of L4 (i.e., the length of the first connecting rod 3) and the distance from the second connection position 32 to the fourth connection position 42, if γ≥90°, a slight external disturbance will cause the filter plate 6 to have a closing tendency; when the sum of L5 and the distance from the first connection position 31 to the third connection position 41 is less than L4 and the sum of the distance from the second connection position 32 to the fourth connection position 42, if γ≥90°, the filter plate 6 will open and close too much if there is no infinite rotation position, and the elastic member 5 will have too little or even no stretching force, which will cause the self-supporting force to disappear and affect the overall stability. The second connecting rod 4 needs to be under pressure. When α=γ+90°, the second connecting rod 4 and the first connecting rod 3 are perpendicular to each other and are in a critical state. If α continues to increase, the above-mentioned self-supporting force disappears.

[0041] See also Figure 1 In the filter assembly of this embodiment, the connecting plate 1 includes a first connecting surface 11 and a second connecting surface 12, the first connecting surface 11 and the second connecting surface 12 are perpendicular to each other, the first connecting surface 11 is connected to the first connecting rod 3 and the second connecting rod 4 respectively, and the second connecting surface 12 is connected to the filter plate 6 so that the connecting plate 1 is perpendicular to the filter plate 6.

[0042] See also Figure 1 In the filter assembly of this embodiment, a plurality of fixing holes are provided on the second connection surface 12, and the filter assembly further comprises a plurality of fixing members 7, each fixing member 7 passes through each fixing hole to connect the filter plate 6 and the connecting sheet 1, and the fixing members 7 are detachably provided so that the connecting sheet 1 and the filter plate 6 are detachably connected. The fixing members 7 are bolts, and the fixing holes are threaded holes, so that the connecting sheet 1 and the filter plate 6 are threadedly connected, and the two are detachable, so as to facilitate the regular replacement of the filter plate 6. The connecting sheet 1 and the filter plate 6 are connected by threads, and can also be connected by buckles, slots, etc.

[0043] See also Figure 2In the filter assembly of the present embodiment, the fixing plate 2 includes a first fixing plate 21 and a second fixing plate 22, the first fixing plate 21 and the second fixing plate 22 are arranged vertically, and the first fixing plate 21 and the second fixing plate 22 are rectangular structures, so that the fixing plate 2 is an L-shaped structure. When the first connecting rod 3 is parallel to the filter plate 6, the first fixing plate 21 abuts against the filter plate 6, the second connecting position 32 is arranged on the first fixing plate 21, the fourth connecting position 42 is arranged on the second fixing plate 22, and the sixth connecting position 52 is located at the corner of the L-shaped structure. The fixing plate 2 is an L-shaped structure, the second connecting position 32 is arranged on the first fixing plate 21, and the fourth connecting position 42 is arranged on the second fixing plate 22. This design reduces consumables and saves costs. The sixth connecting position 52 is located at the corner of the L-shaped structure, increasing the connection distance between the connecting plate 1 and the fixing plate 2, thereby increasing the spring tension.

[0044] See also Figure 5 and Figure 6 In the air conditioner of this embodiment, a housing 8 is included, and the filter assembly as described above is included. The housing 8 is provided with an installation opening 81, and the fixing plate 2 is fixed to the housing 8 through the installation opening 81, and the fixing plate 2 is detachably connected to the housing 8. The edge of the housing 8 of the air conditioner unit is provided with an installation opening 81, and the fixing plate 2 is fixed to the housing 8, and the filter plate 6 is opened to inspect the interior, and the filter plate 6 is closed to achieve the filtering and dust removal function, and the loading and unloading is simple and efficient. After the filter assembly is installed on the housing 8, there is no obvious protruding part on the return air side and the overall size of the unit is reduced, which is easier to complete the installation work in a narrow channel compared with the prior art.

[0045] In the air conditioner and air conditioning unit of this embodiment, a filter assembly installation port 81 and screw fixing holes are provided on the housing 8, and two filter plates 6 (such as Figure 5 As shown), the same direction, opposite direction or reverse direction installation can also be selected to complete the matching of the filter assembly and the unit, and the position of the installation port 81 is adjusted accordingly according to the installation method.
