[0051] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0052] Currently available filters are usually fixedly installed between the air outlet and the fan of the air supply device to filter the incoming air flow. However, for some air supply devices with reversible air outlet functions, their air outlets sometimes serve as air inlets and sometimes as air outlets. When the air outlet serves as an air outlet, the filter provided between the air outlet and the fan will hinder the air supply effect of the air supply device. The embodiment of the present utility model proposes a gas processing component, an air duct component and an air conditioner, which are provided with a filter that can be folded and unfolded, and the filter is provided to be linked with the fan housing, so that when the air outlet of the air supply device serves as an air inlet to take in air, the rotation of the fan housing can achieve the filter covering the air inlet side of the fan housing to achieve the filtering effect on the incoming air flow. When the air outlet of the air supply device serves as an air outlet to discharge air, the rotation of the fan can also achieve the elimination of the filter blocking the air inlet side of the fan housing, thereby avoiding the filter affecting the air supply effect of the air supply device.

[0053] The following is combined with Figure 1 -Attached Figure 11 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0054] Example

[0055] like Figure 1-Figure 5 As shown, the first aspect of the embodiment of the present invention provides a gas processing assembly, comprising:

[0056] A fan housing 100 with a built-in fan, the fan housing 100 has an air inlet and an air outlet, and the fan housing 100 can drive the fan to rotate as a whole around a preset rotation axis to switch the positions of the air inlet and the air outlet;

[0057] The filter 200 includes a fixed portion 201 and a movable portion 202 connected to the fixed portion 201. The movable portion 202 can be expanded or folded under the action of an external force. Preferably, the movable portion 202 can be expanded when pulled by an external force and can be folded under an external pressure. The fixed portion is fixed when the fan housing 100 rotates. The movable portion 202 is connected to the fan housing so that the fan housing 100 can be rotated to achieve an expansion or folding operation. Preferably, the filter 200 is pulled and squeezed by the forward and reverse rotation of the fan housing 100 to achieve the expansion or folding action of the filter 200.

[0058] When the fan housing 100 rotates clockwise, the movable portion 202 of the filter 200 can be expanded along with the rotation of the fan housing 100 to cover the air inlet side of the fan housing 100. When the fan housing 100 rotates counterclockwise, the movable portion of the filter 200 can be folded along with the rotation of the fan housing to eliminate the coverage of the air inlet side of the fan housing 100. That is, when the fan housing 100 rotates clockwise, the filter 200 can be pulled and expanded by the fan housing 100 to cover the air inlet side of the fan housing 100. When the fan housing 100 rotates counterclockwise, the movable portion of the filter 200 can be squeezed and folded by the fan housing 100 to eliminate the coverage of the air inlet side of the fan housing 100.

[0059] In the embodiment of the present invention, a filter screen 200 that can be folded and unfolded is provided, and the filter screen 200 is arranged to be linked with the fan housing 100. In this way, when the air outlet of the air supply device serves as an air inlet, the rotation of the fan housing 100 can pull the active part 202 of the filter screen in the folded state, so that the filter screen 200 covers the air inlet side of the fan housing 100, thereby achieving a filtering effect on the incoming air flow. When the air outlet of the air supply device serves as an air outlet, the reverse rotation of the fan housing 100 can also squeeze the active part 202 of the filter screen in the unfolded state, so as to eliminate the obstruction of the filter screen 200 on the air inlet side of the fan housing 100, thereby avoiding the filter screen 200 affecting the air supply effect of the air supply device.

[0060] That is, the pulling and squeezing mentioned above in the embodiment of the present invention are explained for different states of the movable part 202 of the filter screen. When the movable part of the filter screen is in a folded state, when a force is applied to the movable part of the filter screen toward the side away from the folding direction of the movable part of the filter screen, the movable part of the filter screen in the folded state 202 can be unfolded. When the movable part of the filter screen is in an unfolded state, when a force is applied to the movable part of the filter screen toward the side close to the folding direction of the movable part of the filter screen, the movable part of the filter screen in the unfolded state 202 can be folded.

[0061] Specifically, Figure 10 and Figure 11Take the cabinet air conditioner in the example.

[0062] like Figure 10 As shown, when the upwind port of the cabinet air conditioner is used as the air inlet, the fan housing 100 can be controlled to rotate so that the air inlet side of the fan housing 100 faces the upwind port. At this time, the filter 200 linked to the fan housing 100 is driven by the fan housing 100 and unfolded to cover the air inlet side of the fan housing 100. When the fan housing 100 is running, the airflow entering from the upwind port can be filtered by the filter before passing through the fan housing 100, thereby achieving a filtering effect on the intake airflow.

[0063] like Figure 11 As shown, when the upwind port of the cabinet air conditioner is used as the air outlet, the fan housing 100 can be controlled to rotate so that the air outlet side of the fan housing 100 faces the upwind port. At this time, the filter 200 linked to the fan housing 100 is driven by the fan housing 100 and folded on the outer peripheral side of the fan housing. When the fan housing 100 is running, the air inlet side of the fan housing 100 is not blocked by the filter 200, so the air flow can be discharged directly through the upwind port without resistance loss.

[0064] It should be noted that the above Figure 10 and Figure 11 When taking the cabinet air conditioner as an example, the fan housing 100 and the filter 200 mentioned are only described for the fan housing 100 and the filter 200 arranged near the upwind port.

[0065] It should also be noted that the clockwise rotation and counterclockwise rotation mentioned in the embodiment of the present invention are only for illustrating the relative rotation direction relationship of the fan housing 100, and are not necessarily the same as the rotation direction of the fan housing 100 in a certain figure.

[0066] In some embodiments, as Figure 1-Figure 5 As shown, the movable portion 202 of the filter 200 is connected to the outer peripheral side of the fan housing 100, and can be unfolded and folded following the rotation of the fan housing 100;

[0067] When the fan housing 100 rotates clockwise, the movable portion 202 of the filter 200 can be driven to unfold and form an arc-shaped filter covering the air inlet side of the fan housing 100 .

[0068] The movable portion 202 of the filter in the embodiment of the present invention is constructed in an arc shape when covering the air inlet side of the fan housing 100, which can increase the filtering area of ​​the filter 200. At the same time, the filter 200 with an arc-shaped structure after unfolding can also effectively prevent dust from accumulating on the filter {relative to a straight-faced filter}.

[0069] In some embodiments, as Figure 1-Figure 5 As shown, preferably, the movable portion 202 of the filter screen forms a semicircular structure surrounding the outer periphery of the fan housing 100 when in the folded state;

[0070] The filter net, which has a semicircular structure after folding, is located in the middle position of the fan housing in the axial direction of the fan housing, so that the movable part 202 of the filter net can form a hemispherical structure covering the air inlet side of the fan housing 100 and at least partially surrounding the outer periphery of the fan housing 100 when it is in the unfolded state.

[0071] That is, in the embodiment of the present invention, by cooperating the movable portion 202 of the filter with the middle position of the fan housing 100, this design can ensure that the filter can cover the entire fan housing when unfolded, thereby achieving a better dust-proof function of the filter.

[0072] In some embodiments, as Figure 4 and Figure 5 As shown, the fixed portion 201 of the filter 200 includes a fixed frame, and the movable portion 202 of the filter 200 includes a plurality of movable frames 2021 and a plurality of filter bodies 2022, wherein a filter body 2022 is provided between the fixed frame and the movable frame 2021 and between two adjacent movable frames 2021;

[0073] The multiple movable frames 2021 and the multiple filter mesh bodies 2022 are driven to unfold when the fan housing 100 rotates clockwise, and the multiple movable frames 2021 and the multiple filter mesh bodies 2022 are driven to fold when the fan housing 100 rotates counterclockwise;

[0074] The multiple movable frames 2021 are used to support the filter mesh bodies 2022 when the multiple filter mesh bodies 2022 are unfolded.

[0075] That is, the filter screen 200 in the embodiment of the present invention is composed of a rigid part skeleton and a flexible part filter screen body. The rigid part skeleton is used to support the flexible filter screen body while fixing the position of the filter screen 200, so as to avoid large shaking of the filter screen when filtering the intake air flow after unfolding and to improve the overall rigidity strength of the filter screen 200.

[0076] In some embodiments, a card interface 101 is provided on the outer peripheral side of the fan housing 100, and the card interface 101 is used to engage with the movable part 202 of the filter 200 so as to drive the movable part 202 of the filter 200 to expand or fold when the fan housing 100 rotates.

[0077] That is, the fan housing 100 and the filter 200 in the embodiment of the present invention are detachable structures. When the filter 200 is installed, the fixed part 2021 of the filter 200 can be fixed, and the movable part of the filter 200 can be connected to the card interface 101 on the outer periphery of the fan housing 100, so that the filter 200 can be unfolded and folded by rotating the fan housing 100.

[0078] In some embodiments, as Figure 1-Figure 3 As shown, the fan housing 100 is an axial flow fan housing with a ring-shaped outer periphery and an air inlet and an air outlet formed on both axial sides;

[0079] The filter 200 is detachably connected to the outer peripheral side of the axial flow fan housing.

[0080] In the embodiment of the present invention, the fan housing 100 is set as an axial flow fan, and combined with the installation of the filter 200, on the one hand, by controlling the overall rotation of the axial flow fan, a large air volume air supply effect in different air outlet directions can be achieved. On the other hand, the overall rotating fan housing 100 can also achieve a large air volume air supply effect in different air outlet directions while allowing the filter to selectively cover the air inlet of the fan housing 100, thereby achieving a reversible air supply effect while ensuring the air supply effect and the filtering effect.

[0081] like Figure 6-Figure 8 As shown, further, the second aspect of the embodiment of the present invention also provides an air duct component, which includes an air supply duct and a gas processing component arranged inside the air supply duct, and the gas processing component is the gas processing component provided by the first aspect of the embodiment of the present invention.

[0082] in Figure 6 The filter in the air duct is in a folded state. Figure 7 The filter in the air duct is in an intermediate state between the folded state and the unfolded state {i.e. Figure 7 The filter in is not fully expanded}, Figure 8 The filter in the air duct is in the unfolded state {i.e. Figure 8 The filter in the fully expanded.

[0083] like Figures 9-11 As shown, further, the third aspect of the embodiment of the present invention also provides an air conditioner, an air supply duct is formed inside the air conditioner, and the gas processing component provided by the first aspect of the embodiment of the present invention is provided in the air supply duct, or the air duct component provided by the second aspect of the embodiment of the present invention is provided inside the air conditioner.

[0084] Furthermore, the air conditioner further comprises a first air outlet 301 and a second air outlet 302 connected to the air supply duct, and the air conditioner comprises a first air supply path through which the first air outlet 301 takes in air and the second air outlet 302 discharges air, and a second air supply path through which the second air outlet 302 takes in air and the first air outlet 301 discharges air;

[0085] The gas processing assembly has a first working position in which the filter movable part 202 is in an unfolded state and a second working position in which the filter movable part 202 is in a folded state;

[0086] There are two groups of gas processing components, one of which is located close to the first air outlet 301 and the other is located close to the second air outlet 302.

[0087] in

[0088] When the air conditioner supplies air via a first air supply path, with air entering through the first air outlet 301 and air exiting through the second air outlet 302, the gas processing assembly disposed near the first air outlet 301 is controlled to be in a first working position in which the filter movable portion 202 is in an unfolded state. The unfolded filter movable portion 202 is located between the first air outlet 301 and the fan housing 100 and is configured to filter the airflow entering from the first air outlet 301. The gas processing assembly disposed near the second air outlet 302 is controlled to be in a second working position in which the filter movable portion 202 is in a folded state. The folded filter movable portion 202 is located on the outer periphery of the fan housing 100.

[0089] The air conditioner supplies air along a second air supply path in which air is taken in by the second air outlet 302 and air is discharged from the first air outlet 301. The gas treatment component arranged near the second air outlet 302 is controlled to be in a first working position in which the active part 202 of the filter is unfolded. The unfolded active part 202 of the filter is located between the second air outlet 302 and the fan housing 100, and is used to filter the airflow entering from the second air outlet 302. The gas treatment component arranged near the first air outlet 301 is controlled to be in a second working position in which the active part 202 of the filter is folded. The folded active part 202 of the filter is located on the outer peripheral side of the fan housing 100.

[0090] That is, in the embodiment of the present invention, by respectively arranging gas processing components at the two air outlets of the air supply equipment, through the coordinated cooperation relationship of the two gas processing components, it is possible to achieve the air supply effect of maximum air volume while satisfying the air flow filtering effect, regardless of whether the air conditioner supplies air through the first air supply path or the second air supply path.

[0091] Specifically, when the air conditioner supplies air through the first air outlet 301 and the second air outlet 302, the fan disposed near the first air outlet 301 is controlled to be turned on, and the fan disposed near the second air outlet 302 is controlled to be turned on;

[0092] More specifically, when the air conditioner supplies air through the second air supply path with the second air outlet 302 taking in air and the first air outlet 301 discharging air, the fan housing 100 arranged near the second air outlet 302 is controlled to open, and the fan housing 100 arranged near the first air outlet 301 is controlled to open.

[0093] That is, in the embodiment of the present invention, by respectively arranging gas processing components at the two air outlets, the two fan housings 100 in the two gas processing components can be controlled to operate simultaneously when the air conditioner is running, and the air inlet side position of the fan housing 100 and the presentation form of the filter 200 in the gas processing component can be automatically adjusted according to the specific air supply path of the air conditioner. This enables the air supply effect of maximum air volume to be achieved while satisfying the air flow filtering effect, regardless of whether the air conditioner supplies air via the first air supply path or the second air supply path.

[0094] In some embodiments, as Figures 9-11 As shown, the air conditioner includes a housing 300, and a plug-in slot 303 is provided on the housing 300. The plug-in slot 303 is used for inserting the filter 200 into the housing 300 when the filter 200 is in a folded state;

[0095] in

[0096] The filter 200 inserted into the shell 300 can cooperate with the shell 300 through the fixed part 201, so that the fixed part 201 of the filter 200 can be fixed by the shell 300. The filter 200 inserted into the shell 300 can also cooperate with the fan housing 100 through the movable part 202, so that the movable part 202 can be driven by the rotation of the fan housing 100 to realize the unfolding and folding action.

[0097] In some embodiments, the air conditioner further comprises:

[0098] The cover plate 500 is used to seal the insertion slot 303 on the housing 300 .

[0099] That is, the filter 200 in the embodiment of the present invention can be installed from the outside of the air conditioner into the air conditioner housing and, after installation, secured by the cover 500. Since the filter 200 can be installed separately from the outside of the air conditioner, after using the filter 200 for a period of time, the filter 200 can be removed and cleaned separately without disassembling the air conditioner housing, thereby facilitating subsequent cleaning of the filter.

[0100] The cover plate 500 and the fixed portion 201 of the filter 200 can be integrally formed or separately formed. The specific connection between the cover plate and the filter 200 is not limited in the present embodiment. However, it is relatively preferred that the cover plate 500 and the filter 200 be separated, as this facilitates assembly and disassembly of the filter 200 and the cover plate 500.

[0101] In some embodiments, as Figures 9-11 As shown, the air conditioner is a cabinet air conditioner, in which case the first air outlet 301 is an upper air outlet provided at the top of the cabinet air conditioner, and the second air outlet 302 is a lower air outlet provided at the bottom of the cabinet air conditioner;

[0102] The cabinet air conditioner further includes a heat exchanger 400 disposed between the two groups of gas processing components, for exchanging heat on the airflow when the air conditioner supplies air via the first air supply path or the second air supply path.

[0103] In order to facilitate understanding of the overall solution in the embodiment of the present utility model, the following Figures 1-11 The structure and working principle of the utility model are described in detail:

[0104] Overall structure introduction: Figure 10 This is a schematic diagram of the exploded structure of the air conditioner in an embodiment of the present utility model. The shell 300 in the figure is composed of a front shell and a rear shell connected together, and the internal cavity of the shell is the air duct of the air conditioner; the grille 600 plays a rectifying role; the filter 200 arranged on the upper and lower sides of the air conditioner can prevent dust and other debris in the air from being sucked into the interior of the air conditioner, as well as the axial fan blades and axial fan casing arranged on the upper and lower sides of the air conditioner, the axial fan blades and the axial fan casing are combined to form a fan casing 100, which is rotatably placed in the air duct as a whole, and the cover plates 500 arranged on the upper and lower sides of the air conditioner are used to cover the gap for removing the filter and to press the filter.

[0105] Filter structure and design requirements: The retractable filter structure proposed in the embodiment of the present invention is as follows Figure 4 and Figure 5 As shown, there are independent rigid frames on both sides of the filter to strengthen the overall structural strength and for installation and fixation. The middle part is a filter mesh material {i.e. the filter body 2022 mentioned above} that has the function of filtering air impurities, which is used to filter the air sucked into the air conditioner. The filter mesh material is fixed on the filter frame and can be driven by the filter frame to perform expansion and contraction movements to ensure that the frame on one side is fixed and the frame on the other side is flipped to move the filter from the expanded state to the retracted state. The shape of the filter is designed according to the shape of the fan, but it is necessary to ensure that the filter can completely cover the fan assembly in the expanded state to avoid insufficient air filtration. At the same time, it also avoids uneven distribution of intake resistance due to incomplete coverage of the filter, thereby causing sound quality problems such as surging.

[0106] Filter storage status: The storage status of the filter is as follows: Figure 4 As shown, Figure 4 The function of the leftmost movable frame 2021 of the middle filter is to be assembled on the fan housing 100 and drive the filter movable part 202 to move when the fan housing 100 rotates. Figure 4 The rightmost fixed frame 201 is fixed to the air conditioner's outer shell to secure the entire filter. At the filter's operating outlet, the filter rotates from an extended to a stowed position as the fan rotates. When the filter is stowed, multiple movable frames 2021 fold together and are stored alongside the fixed frame 2011 on the side of the fan housing 100. The filter mesh 2022 is stored between the frames, with the number of frames designed based on actual conditions.

[0107] Filter Assembly: When the filter is installed in the air conditioner, it is inserted into the air duct from outside the air conditioner housing in a folded state. The movable frame 202 of the filter 200 engages with the snap-fit ​​interface 101 of the fan housing 100, while the other side snaps into place with the air conditioner housing. As the fan housing 100 rotates, the fixed frame 201, which is fixed to the air conditioner housing, remains stationary, while the movable frame 2021, which engages with the fan, rotates with the fan, allowing the filter to be deployed and retracted. The snap-fit ​​interface of the fan housing 100 engages with the movable frame 2021 of the filter, with the mating portion located midway between the upper and lower portions of the fan housing 100. This design ensures that the filter completely covers the air inlet of the fan housing 100 when deployed, achieving its dust-proof function. The portion of the filter 200 that engages the air conditioner housing is secured to the outside by a cover plate 500. This cover plate not only secures the filter but also ensures a tight seal.

[0108] The working principle of the upper and lower filter screens: The upper air outlet mode of the cabinet air conditioner in the embodiment of the present invention is as follows: Figure 11 As shown, at this time, the axial flow blades in the fan housing 100 discharge air vertically upward, the filter 200 at the bottom is unfolded to prevent dust, and the filter 200 at the top is stored and folded. At this time, the filter 200 at the top is stored and folded on the outer peripheral side of the fan housing 100 and will not affect the air outlet; the lower air outlet mode is as shown Figure 10 As shown, in this working state, the filter 200 located at the top is unfolded to prevent dust, and the filter 200 located at the bottom is folded. Figure 11 Switch to downwind mode Figure 10 The process is as shown Figure 6 、 Figure 7 and Figure 8As shown, in this process, the upper filter 200 moves from storage to expansion, and the lower filter 200 moves from expansion to storage. The movement principle is the same, and the upper filter 200 is used as an example for explanation: Figure 6 、 Figure 7 and Figure 8 As shown, when switching from top to bottom airflow, the upper fan housing 100 rotates 180° counterclockwise around its center of rotation until the axial flow blades discharge air vertically downward, achieving bottom airflow. Because the movable frame 2021 is inserted into the snap-in connector 101 of the fan housing 100 during installation of the filter 200, the snap-in connector 101 drives the movable frame 2021 to rotate synchronously during the rotation of the fan housing 100. At this point, the fixed frame 201 of the filter 200 is fixed to the air conditioner housing, and the movable frame 2021 rotates counterclockwise relative to the fixed frame 201, deploying the filter 200. Air is now drawn into the air conditioner through the top air vent, passing through the fan housing 100 and then outward. Once deployed, the filter 200 is positioned between the fan housing 100 and the top air vent, filtering the drawn air. To return to the top airflow mode, the fan simply rotates 180° clockwise to retract the upper filter 200, while the lower filter 200 deploys.
