Wherein, the fixed connecting piece can be a sewing rope, and the sealing part 11 and the filtering part 12 are sewed.

In some embodiments, the sealing portion 11 and the filter portion 12 are integrally formed to constitute a filter screen body.

In some embodiments, the seal 11 comprises a non-porous portion; or, a microporous part having a mesh aperture smaller than or equal to a set value is included. And the sealing function is achieved.

Alternatively, the sealing portion 11 is a non-porous portion, i.e. a structural portion without meshes. Wherein the absence of the mesh means a structure in which the mesh is not macroscopically observed.

Alternatively, the sealing portion 11 is a microporous portion having a mesh aperture smaller than or equal to a set value. The set value can be determined according to actual conditions, such as 0.1mm and the like.

In the embodiment of the present disclosure, the filtering portion 12 is a structural portion capable of performing a filtering function, and is capable of ventilating and filtering foreign matters.

In some embodiments, filter portion 12 includes one or more filter subregions having different mesh apertures. When more than one (i.e. two or more) filtering sub-area is included, different filtering effects may be achieved. I.e. there is a difference in mesh pore size between two or more filter sub-regions. When the filter portion 12 includes one filter subregion, the pore sizes of the meshes in the one filter subregion may be the same or different.

As shown in fig. 1, the filter net 10 includes a non-porous sealing part 11 and a filter part 12, and the filter part 12 includes a first filter sub-area 121 and a second filter sub-area 122. Wherein, the mesh aperture in each filtration subregion can be the same, also can be different. The filter portion 12 of the filter net 10 is not limited to the two filter subregions shown in fig. 1, and may be more, and the number is not limited.

In some embodiments, the mesh pore size in each filter sub-region is the same. Achieving consistent filtering effect.

In some embodiments, the mesh pore size in each filter sub-region is the same; and the aperture of the meshes of more than one filter subarea is changed according to a set direction by a first set rule. The first setting rule may be gradually increasing, or gradually decreasing, or the mesh aperture size may be set at intervals, and the first setting rule is not limited.

In some embodiments, the mesh pore size of more than one filter sub-region increases progressively or decreases progressively in a direction away from the seal 11. As shown in fig. 1, the mesh pore size of the first filter subregion 121 is smaller than that of the second filter subregion 122, that is, the mesh pore sizes of the first filter subregion 121 and the second filter subregion 122 are gradually increased in a direction away from the seal 11. Optionally, the mesh aperture of the first filtering subregion 121 is 0.5mm and the mesh aperture of the second filtering subregion 122 is 3 mm.

The second setting rule includes, but is not limited to, an increase or decrease in the aperture of the mesh along a set direction. Here, the setting direction may be a direction away from the sealing portion 11 or a direction toward the sealing portion 11.

In some embodiments, the mesh pore size in each filter sub-region increases in a direction away from the seal 11. Optionally, the mesh pore size in each filter sub-region increases uniformly by a set ratio. The set ratio is not limited, and optionally, the pore size of each row or more than one row of meshes in each filter subarea is increased by 0.5-5%.

Alternatively, referring to fig. 2, in the first filtering subregion 121, the pore size of each row or more than one row of meshes is uniformly increased from 0.2mm to 2mm at a ratio of 2%. In the second filtering subregion 122, the aperture of each row of meshes is uniformly increased from 3mm to 5mm in a proportion of 1%. Here, it is only an example, and the adaptive adjustment may be performed according to actual needs, such as the area of the filtering path, the air volume, and the like.

In some embodiments, referring to fig. 2, the mesh apertures of more than one filter sub-region of the filter portion 12 engage the transition. That is, the whole mesh aperture of the filter portion 12 changes at a set regular rate along a set direction, and, equivalently, the filter portion 12 includes one filter sub-area in which the mesh aperture changes at a set regular rate along a set direction. That is, there is no significant margin of variation in mesh pore size between adjacent filter subregions. Alternatively, the mesh aperture of the filter portion 12 is changed in a set direction in a set ratio. Alternatively, the pore size of each row or more than one row of meshes of the filter portion 12 is uniformly changed in a direction away from the seal portion 11 in a set ratio. The setting ratio is not limited, and optionally, the pore size of each row of meshes in each filter subarea is increased by 0.5-5%.

Alternatively, referring to fig. 2, in the first filtering subregion 121, the pore size of each row of meshes is uniformly increased from 0.2mm to 2mm (including 2mm) at a ratio of 2%. In the second filtration subregion 122, the pore size of the meshes of each row is uniformly increased from 2mm (excluding 2mm) to 5mm at a ratio of 1%. Here, it is only an example, and the adaptive adjustment may be performed according to actual needs, such as the area of the filtering path, the air volume, and the like.

In the embodiment of the disclosure, the mesh aperture of the filter subarea is not limited and can be determined according to the actual application condition. Optionally, the mesh aperture of the filtering subarea is in the range of 0.2-5 mm.

In some embodiments, the mesh aperture of at least one of the more than one filtering subareas is in the range of 0.2-2 mm, so that the dust removal and filtration effects are enhanced. For example, as shown in FIG. 1, the first filtering subregion 121 has a mesh aperture in the range of 0.2 to 2mm, for example, 0.5 mm.

In some embodiments, at least one of the more than one filter subareas has a mesh aperture within the range of 2-5 mm, which enhances the intake air volume. For example, as shown in FIG. 1, the second filter subregion 122 has a mesh opening size in the range of 2 to 5mm, for example, 3 mm.

Of course, the filter portion 12 of the filter screen 10 in the embodiment of the present disclosure is not limited to the case with two filter subregions shown in fig. 1, and one or more filter subregions may be added to increase the functionality of the filter screen 10 to meet different requirements. Moreover, according to the actual situation, the area of each filtering sub-region is not limited, and the area of each filtering sub-region can be matched with the filtering path; it is also possible to adapt the area of two or more adjacent filter subregions to the filter path.

In some embodiments, the filter screen 10 further includes an adjusting portion 13, and the adjusting portion 13 is disposed at two ends of the filter screen body. The two ends are the two ends in the running direction when the filter screen is switched. The adjusting part 13 provides adjusting allowance for the different functional parts of the filter screen during the switching movement. For example, in the filter screen assembly described below, the adjusting unit 13 is disposed on the switching mechanism, and further, the filter screen is driven to switch between different functions.

In some embodiments, as shown in fig. 3, the adjusting unit 13 includes a pulling rope, and the pulling rope is connected to both ends of the filter screen body. That is, a pulling string is connected to each of the end of the sealing part 11 and the end of the filter part 12. Optionally, two or more pull cords are provided at each end to avoid shifting during the switching movement.

Wherein, the first state is that the sealing part 11 of the filter screen 10 is shielded on the filter path; in the second state, the filter portion 12 of the filter screen 10 is blocked from the filter path.

In the embodiment of the disclosure, the filter screen component realizes the switching of the filter screen among different functions, and the filter screen 10 performs a sealing function when in a first state, thereby effectively preventing foreign matters from entering; the filter screen 10 performs a filtering function in the second state.

The filtering path refers to a flow path of a fluid to be filtered. For example, when the filter screen assembly is assembled to an air conditioner indoor unit, the filter path is a flow path of air entering the indoor unit. Such as the air inlet of the indoor unit.

In the embodiment of the present disclosure, the switching mechanism is used to drive the filter screen 10 to perform function switching, so that different functional areas of the filter screen 10 are shielded on the filtering path. For example, when the filter screen assembly is applied to an indoor unit of an air conditioner, the filter screen assembly is disposed on the air inlet, and the first state of the filter screen 10 is that the sealing part 11 of the filter screen 10 is shielded on the air inlet; in the second state, the filter part 12 of the filter screen 10 is shielded on the air inlet.

In some embodiments, the switching mechanism includes two driving units (a first driving unit 21 and a second driving unit 22), the two driving units are arranged in parallel, and two ends of the filter screen 10 are respectively arranged on the two driving units; the switching of the filter screen 10 between the first state and the second state is achieved in cooperation with the two drive units, for example, by a change in the drive direction of the two drive units.

As shown in fig. 4, one end of the sealing part 11 is provided on the first driving unit 21, and one end of the filter part 12 is provided on the second driving unit 22. When the filter unit 12 is rotated clockwise, the sealing unit 11 is unfolded and shielded from the filtering path as the filter unit 12 is wound on the second driving unit 22. When the sealing part 11 rotates counterclockwise, the sealing part is wound around the first driving unit 21, and the filter part 12 is unfolded and shielded on the filter path.

Optionally, each driving unit comprises a driving motor 201 and a rotating shaft 202, and the rotating shaft 202 is arranged at the output end of the driving motor 201; both ends (e.g., the adjusting portion 13) of the filter net 10 are wound around the two rotating shafts 202, respectively. The driving motor 201 drives the rotating shaft 202 to rotate, and the filter screen 10 is switched between the first state and the second state under the matching of the two rotating shafts.

For example, referring to fig. 6, when the filter screen assembly is assembled on the air inlet of the indoor unit of the air conditioner, two driving units are parallelly fixed on the air conditioner body 30 (e.g., air conditioner bracket or air conditioner casing) on two opposite sides of the air inlet, the driving motor 201 is fixed on the air conditioner body 30 on two opposite sides of the air inlet, one end of the rotating shaft 202 is connected to the output shaft of the driving motor 201, and the other end is movably connected to the air conditioner body 30, for example, movably connected to the air conditioner body 30 through a bearing.

In some embodiments, the screen assembly, as shown with reference to fig. 7 and 8, further comprises a support 23; the support 23 is arranged to provide support and/or guidance to the filter screen. The support member 23 can provide support for the filter screen during switching of the filter screen 10, so that the filter screen 10 has support during movement to prevent deformation. Alternatively, the filter screen 10 may be used as a guide for the filter screen 10, so that the filter screen 10 moves along a set path during movement. Alternatively, the support 23 provides both support and acts as a guide. For example, when the assembled filtering path has a curved surface, the supporting member 23 is configured in a curved shape following the filtering path, so that the filtering net 10 moves along the supporting member 23 and can be hidden on the filtering path following the shape of the supporting member 23. Of these, only part of the filter screen 10 is shown in fig. 7 and 8.

In some embodiments, as shown in fig. 7 and 8, the supporter 23 includes a first sub-supporter 231 and a second sub-supporter 232, the first sub-supporter 231 and the second sub-supporter 232 are disposed in parallel with each other, and a receiving channel 230 is formed therebetween; the filter screen 10 is inserted through the receiving passage 230.

In some embodiments, the first sub-supporter 231 and the second sub-supporter 232 are both supporting frames having the same structure; the two supporting frames are arranged in parallel in a way that the surfaces are opposite, and an accommodating channel is formed between the two supporting frames; the filter screen is arranged through the containing channel in a penetrating way. The first sub-support 231 and the second sub-support 232 may have a connection relationship therebetween, for example, a connection structure 233 is provided on the side of the first sub-support 231 and the second sub-support 232 parallel to the channel direction in the accommodating channel 230, and the connection structure 233 may be a connection rib (as shown in fig. 8) or a connection plate. Alternatively, the first sub-supporter 231 and the second sub-supporter 232 may be disposed on an external member (e.g., the air conditioner body 30) independently from each other without a connection relationship (as shown in fig. 7), and the receiving passage 230 may be formed therebetween.

In some embodiments, as shown in fig. 7, the first sub-supporting unit 231 (or, the second sub-supporting unit 232) includes an outer frame 2301 and supporting ribs 2302, the size of the outer frame 2301 is matched with the size of the filter net 10, and the supporting ribs 2302 are disposed in the outer frame 2301. The number and arrangement of the support ribs 2302 are not limited, and as shown in fig. 7, a plurality of support ribs 2302 are arranged in a vertically and horizontally alternating manner.

In some embodiments, the support 23 is obtained using 3D printing techniques. The support piece 23 obtained by 3D printing is thin and can be controlled to be less than 3mm in thickness, so that the assembly space is reduced, and the attractiveness of the air conditioner is improved. Optionally, the first sub-support 231 and the second sub-support 232 are both obtained by using a 3D printing technique.

In some embodiments, as shown in fig. 6, the filter screen assembly further includes a dust removing mechanism 24, and the dust removing mechanism 24 is disposed on a moving path of the filter screen 10 to remove dust from the filter screen 10. During the movement of the filter screen 10, the dust removing mechanism 24 cleans the filter screen 10, so as to achieve the effect of cleaning the filter screen.

In some embodiments, the dust removing mechanism 24 is disposed on a movement path of a side of the filter screen 10 close to the driving unit (the first driving unit 21 or the second driving unit 22). Effectively preventing dust from being brought into the air conditioner by air. Alternatively, the drive unit is a drive unit that provides the filter portion 12, such as the second drive unit shown in fig. 4. When the air conditioner is started or shut down, the dust removing mechanism can remove dust from the filter part 12 and keep the filter part 12 clean.

In some embodiments, the dust removing mechanism 24 includes a dust removing member 241 and a dust collecting member 242, the dust removing member 241 is disposed on a moving path of the filter screen 10 and is in contact with the filter screen 10, and the dust collecting member 242 is disposed on a path where dust falls. As shown in fig. 6, when applied to an air conditioner in which the air inlet is located at the bottom, the dust removing member 241 is disposed at the inner side of the filter screen 10 (i.e., inside the air conditioner), and the dust collecting member 242 is disposed at the outer side of the filter screen 10 located below the dust removing member.

The embodiment of the present disclosure further provides an air conditioner, including the filter screen assembly; the filter screen assembly is arranged on the air conditioner in a way that the filter screen 10 of the filter screen assembly can shield the air inlet of the air conditioner. Referring to fig. 6, only a partial structure of the intake vent portion is shown in fig. 6.

In the embodiment of the present disclosure, under the condition that the air conditioner is in different states, the sealing portion 11 or the filtering portion 12 of the filter screen 10 is controlled to shield the air inlet, so that the filter screen 10 performs different functions. When the air conditioner is running, the filter part 12 of the filter screen 10 is sheltered on the air inlet to perform the filtering function. When the air conditioner is closed, the sealing part 11 of the filter screen 10 is shielded on the air inlet, and the sealing part seals the air inlet to perform a sealing function, so that dust is prevented from entering the air conditioner, the dust is prevented from entering the air conditioner when the air conditioner is not used, and the interior of the air conditioner is kept clean.

The embodiment of the disclosure also provides a filter screen control method of an air conditioner, and the air conditioner adopts the air conditioner. As shown in fig. 9, the control method includes:

and S100, under the condition that the air conditioner is in the running state, controlling the filtering part 12 of the filtering net 10 to shield the air inlet of the air conditioner.

For example, the filter part 12 includes 4 filter subregions, the mesh aperture of the first filter subregion is 0.5mm, the mesh aperture of the second filter subregion is 1mm, the mesh aperture of the third filter subregion is 3mm, and the mesh aperture of the fourth filter subregion is 5 mm. When the operation mode of the air conditioner is the fresh air mode, the target filtering subarea is the first filtering subarea, so that the first filtering subarea is shielded on an air inlet of the air conditioner, and the filtering effect is enhanced. When the operation mode of the air conditioner is a conventional heating/refrigerating operation mode, one of the second filtering sub-area to the fourth filtering sub-module can be shielded on an air inlet of the air conditioner according to the requirement on the air volume, and the air volume is ensured during filtering.

The setting value is pre-configured, and different setting values can be set according to different air volume modes of the air conditioner.

For example, when the air conditioner is in a normal heating/cooling mode, the air volume is a medium air volume, and a third filter subarea (with a mesh aperture of 3mm) of a filter screen (see the filter screen with 4 filter subareas) is shielded on an air inlet of the air conditioner. When the air pressure difference between the two sides of the filter screen is larger than a set value (corresponding to a middle gear), the filter screen is controlled to move, so that part or all of the fourth filter subarea is shielded on the air inlet of the air conditioner, and the mesh aperture of the filter screen shielded on the air inlet of the air conditioner is increased. And continuously collecting the wind pressure difference in the movement process of the filter screen, and stopping the filter screen when the wind pressure difference is less than or equal to a set value (corresponding to a middle gear).
