[0051] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0052] At present, the existing filter is 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 function, the air outlet is sometimes used as an air inlet and sometimes as an air outlet. When the air outlet is used as an air outlet, the filter arranged between the air outlet and the fan will hinder the air supply effect of the air supply device. The embodiment of the present invention 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 arranged to be linked with the fan housing, so that when the air outlet of the air supply device is used as an air inlet to take in air, the filter can be covered on the air inlet side of the fan housing by the rotation of the fan housing to achieve the filtering effect of the incoming air flow. When the air outlet of the air supply device is used as an air outlet to discharge air, the fan can be rotated to eliminate the blocking of the filter on 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 Fig.11 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[0054] Example

[0055] like Figure 1-Figure 5 As shown, a first aspect of an embodiment of the present invention provides a gas processing component, 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, wherein the movable portion 202 can be unfolded or folded under the action of an external force. Preferably, the movable portion 202 can be unfolded when pulled by an external force and can be folded under the pressure of an external force. The fixed portion is fixed when the fan housing 100 rotates. The movable portion 202 is connected to the fan housing so that the unfolding or folding operation can be realized by the rotation of the fan housing 100 when the fan housing 100 rotates. Preferably, the pull and compression of the filter 200 are realized by the forward and reverse rotation of the fan housing 100 to realize the unfolding or folding action of the filter 200.

[0058] When the fan housing 100 rotates clockwise, the active part 202 of the filter 200 can be unfolded with the rotation of the fan housing 100 to cover the air inlet side of the fan housing 100, and when the fan housing 100 rotates counterclockwise, the active part of the filter 200 can be folded 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 unfolded by the fan housing 100 to cover the air inlet side of the fan housing 100, and when the fan housing 100 rotates counterclockwise, the active part 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 foldable and unfoldable filter 200 is provided, and the filter 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 in the folded state, so that the filter 200 covers the air inlet side of the fan housing 100, thereby achieving a filtering effect on the incoming airflow. 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 in the unfolded state, so as to eliminate the blocking of the filter 200 on the air inlet side of the fan housing 100, thereby preventing the filter 200 from 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 active part 202 of the filter. When the active part of the filter is in a folded state, a force is applied to the active part of the filter toward a side away from the folding direction of the active part of the filter, so that the active part 202 of the filter in the folded state can be unfolded. When the active part of the filter is in an unfolded state, a force is applied to the active part of the filter toward a side close to the folding direction of the active part of the filter, so that the active part 202 of the filter in the unfolded state can be folded.

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

[0062] like Fig.10 As shown, when the upper air outlet 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 upper air outlet. 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 upper air outlet can be filtered by the filter before passing through the fan housing 100, thereby achieving a filtering effect on the intake airflow.

[0063] like Fig.11As shown, when the upper air outlet 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 upper air outlet. 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 airflow can be discharged directly through the upper air outlet without resistance loss.

[0064] It should be noted that the above Fig.10 and Fig.11 When taking the cabinet air conditioner as an example, the fan housing 100 and the filter 200 mentioned are only for explaining the fan housing 100 and the filter 200 arranged close to the upper air outlet.

[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 casing 100, which is not necessarily the same as the rotation direction of the fan casing 100 in a certain figure.

[0066] In some embodiments, 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 part 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 structure after unfolding can also effectively prevent dust from accumulating on the filter {relative to a straight filter}.

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

[0070] The filter net having 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 matching the active part 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, Figure 4 and Figure 5 As shown, the fixed part 201 of the filter 200 includes a fixed frame, and the movable part 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 net 200 in the embodiment of the present invention is composed of a rigid part skeleton and a flexible part filter net body. The rigid part skeleton is used to support the flexible filter net body while fixing the position of the filter net 200, so as to avoid large shaking of the filter net when filtering the intake air flow after unfolding and to improve the overall rigidity strength of the filter net 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 unfold 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, Figure 1-Figure 3 As shown, the fan housing 100 is an axial flow fan housing with a ring-shaped outer circumference and an air inlet and an air outlet formed on both axial sides;

[0079] The filter screen 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 is fully expanded}.

[0083] like Figure 9-11 As shown, further, the third aspect of the embodiment of the present invention also provides an air conditioner, wherein 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 also has a first air outlet 301 and a second air outlet 302 connected to the air supply duct, and the air conditioner has 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 mesh movable part 202 is in an unfolded state and a second working position in which the filter mesh movable part 202 is in a folded state;

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

[0087] in

[0088] When the air conditioner supplies air through the first air supply path with the first air outlet 301 for air intake and the second air outlet 302 for air discharge, the gas processing assembly arranged near the first air outlet 301 is controlled to be in the first working position in which the filter active part 202 is in an unfolded state, and the unfolded filter active part 202 is located between the first air outlet 301 and the fan housing 100, and is used to filter the airflow entering from the first air outlet 301, and the gas processing assembly arranged near the second air outlet 302 is controlled to be in the second working position in which the filter active part 202 is in a folded state, and the folded filter active part 202 is located on the outer peripheral side of the fan housing 100;

[0089] The air conditioner supplies air along a second air supply path in which air is taken in from the second air outlet 302 and air is discharged from the first air outlet 301. The gas processing 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 in an unfolded state, and the unfolded active part 202 of the filter is located between the second air outlet 302 and the fan housing 100, and is used for filtering the airflow entering from the second air outlet 302. The gas processing 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 in a folded state, and 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 device, through the coordinated cooperation relationship of the two gas processing components, it can be achieved that no matter whether the air conditioner supplies air through the first air supply path or the second air supply path, the air supply effect of maximum air volume can be achieved while satisfying the airflow filtering effect.

[0091] Specifically, when the air conditioner supplies air through the first air supply path with the first air outlet 301 for air intake and the second air outlet 302 for air discharge, 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 via 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 disposed near the second air outlet 302 is controlled to open, and the fan housing 100 disposed 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 are automatically adjusted according to the specific air supply path of the air conditioner, so that no matter whether the air conditioner supplies air through the first air supply path or the second air supply path, the air supply effect of maximum air volume can be achieved while satisfying the airflow filtering effect.

[0094] In some embodiments, Figure 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 net 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 net 200 can be fixed by the shell 300. The filter net 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 plug-in 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 housing of the air conditioner, and after installation, it can be fixed by the cover plate 500. Since the filter 200 can be installed separately from the outside of the air conditioner, after the filter 200 has been used for a period of time, the filter can be removed separately for cleaning without disassembling the air conditioner housing, thereby facilitating subsequent cleaning of the filter.

[0100] The cover plate 500 and the fixing part 201 of the filter 200 can be integrally arranged or separately arranged, and the specific connection form between the cover plate and the filter 200 is not limited in the embodiment of the present application. However, it is relatively preferred that the cover plate 500 and the filter 200 are arranged as a separate structure, which is more convenient for the filter 200 and the cover plate 500 to be assembled and disassembled.

[0101] In some embodiments, Figure 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 disposed at the top of the cabinet air conditioner, and the second air outlet 302 is a lower air outlet disposed at the bottom of the cabinet air conditioner;

[0102] The cabinet air conditioner also 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 invention, Figure 1-Figure 11 The structure and working principle of the present invention are specifically described:

[0104] Overall structure introduction: Fig.10 The exploded structure diagram of the air conditioner in the embodiment of the present invention, the shell 300 in the figure is formed by the joint combination of the front shell and the rear shell, the internal cavity of the shell is the air duct of the air conditioner; the grille 600 has a rectifying effect; 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 air conditioner, and the axial flow fan blades and the axial flow fan casing are arranged on the upper and lower sides of the air conditioner, the axial flow fan blades and the axial flow fan casing are combined to form the fan casing 100, which is rotatably placed in the air duct as a whole, and the cover plate 500 arranged on the upper and lower sides of the air conditioner is 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 reinforce 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, and 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 a retracting and expanding movement to ensure that the filter can be moved from the expanded state to the stored state by rotating the frame on one side to flip the frame on the other side. 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 to drive the movable part 202 of the filter to move when the fan housing 100 rotates. Figure 4The fixed frame 201 on the far right is fixed to the outer shell of the air conditioner to fix the filter as a whole. At the air outlet where the filter works, the filter changes from the unfolded state to the stored state as the fan rotates. When the filter is stored, multiple movable frames 2021 are folded together and stored together with the fixed frame 2011 on the side of the fan housing 100. The filter mesh 2022 is stored between the frames, and the number of frames is designed according to the actual situation.

[0107] Assembly of the filter: When the filter is installed in the air conditioner, it is inserted into the air duct of the air conditioner from the outside of the air conditioner housing in a folded state. The movable skeleton 202 on the filter 200 is snap-fitted with the card interface 101 of the fan housing 100, and on the other side, it is snap-fitted with the housing of the air conditioner. When the fan housing 100 rotates, the fixed skeleton 201 fixed on the air conditioner housing does not move, and the movable skeleton 2021 of the matching part with the fan rotates with the fan to realize the unfolding and storage movement of the filter. It can be seen that the card interface of the fan housing 100 cooperates with the movable skeleton 2021 of the filter, and its matching part is in the middle of the upper and lower positions of the fan housing 100. This design can ensure that the filter can cover the entire air inlet of the fan housing 100 when it is unfolded, realizing the dustproof function of the filter. The part where the filter 200 cooperates with the air conditioner housing is fixed on the outside by the cover plate 500. The cover plate not only plays a fixing role but also ensures the sealing of the filter.

[0108] The upper and lower filter screens work switching principle: The upper air outlet mode of the cabinet air conditioner in the embodiment of the present invention is as follows Fig.11 As shown, at this time, the axial flow blades in the fan housing 100 discharge air vertically upward, the filter 200 located at the bottom is unfolded to prevent dust, and the filter 200 located at the top is stored and folded. At this time, the filter 200 located 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 in FIG. Fig.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. Fig.11 Switch to down airflow state Fig.10 The process is as shown Figure 6 , Figure 7 and Figure 8 As shown, in this process, the upper filter 200 is stored and then unfolded, and the lower filter 200 is unfolded and then stored. The movement principle is the same. The upper filter 200 is used as an example for explanation: Figure 6 , Figure 7 and Figure 8As shown, during the process of switching from upper air outlet to lower air outlet, the upper fan housing 100 rotates counterclockwise 180° around the rotation center until the axial flow fan blades vertically discharge air downward, thereby realizing lower air outlet of the air conditioner. Since the movable frame 2021 is inserted into the card interface 101 of the fan housing 100 when the filter 200 is installed, the card interface 101 drives the movable frame 2021 to rotate synchronously during the rotation of the fan housing 100. At this time, the fixed frame 201 of the filter 200 is fixed to the housing of the air conditioner, and the movable frame 2021 rotates counterclockwise relative to the fixed frame 201 to realize the unfolding of the filter 200. At this time, the air flow is sucked into the air conditioner through the top air outlet, and blown downward after passing through the fan housing 100. After the filter 200 is unfolded, it is located between the fan housing 100 and the top air outlet, thereby filtering the inhaled air. When it is necessary to return to the upper air outlet state again, the fan only needs to rotate 180° clockwise to drive the upper filter 200 to be stored and folded, and the lower filter 200 is unfolded at this time.
