Technical Field

[0001] This application relates to the field of intelligent air conditioning equipment technology, such as an air conditioning device and its control method and control device, and an air conditioner. Background Technology

[0002] Existing air conditioning equipment, such as ducted air conditioners, requires the addition of a fresh air module with a fan to provide fresh air functionality. This occupies space inside or outside the unit, resulting in larger equipment size, greater installation space requirements, higher costs, and a poorer user experience.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] This disclosure provides an air conditioning device and its control method and control device, as well as an air conditioner, to solve the technical problem that existing air conditioning devices with fresh air function require an additional fresh air module with a fan on the basis of the original device, which occupies indoor or outdoor space, requires a large installation space, has high cost, and deteriorates the user experience.

[0006] In some embodiments, the air conditioning device includes: a housing having a fan cavity; the housing including an air inlet plate and a fresh air plate for constructing the fan cavity; an air inlet on the air inlet plate and a fresh air inlet on the fresh air plate; a fan disposed in the fan cavity, the fan guiding airflow; wherein, an air intake of the fan disposed near the fresh air plate faces the fresh air inlet, the air intake serving as a fresh air intake; a fresh air transfer structure including a retractable transfer pipe; the transfer pipe being disposed corresponding to the fresh air inlet; when the transfer pipe is extended, it connects to the fresh air intake of the fan disposed near the fresh air plate to draw in fresh air; when the transfer pipe is retracted, the fresh air intake can draw in indoor return air.

[0007] In some embodiments, the control method for the air conditioning equipment includes: in response to a fresh air mode operation signal, controlling the retractable adapter pipe of the fresh air transfer structure to extend and connect to the fresh air intake of a fan located near the fresh air panel; or, in response to an indoor circulation mode operation signal, controlling the retractable adapter pipe of the fresh air transfer structure to retract or remain in a retracted state, so that the fresh air intake of the fan located near the fresh air panel draws in indoor return air.

[0008] In some embodiments, the control device for an air conditioning device includes a processor and a memory storing program instructions, the processor being configured to execute the aforementioned control method for an air conditioning device when executing the program instructions.

[0009] In some embodiments, the air conditioner includes: the aforementioned air conditioning device; and / or, the aforementioned control device for the air conditioning device.

[0010] The air conditioning equipment, control method, control device, and air conditioner provided in this disclosure can achieve the following technical effects: In the air conditioning device of this embodiment, a fresh air inlet is opened on the fresh air plate of the fan cavity, and an air intake (as a fresh air intake) of a fan located near the fresh air plate is oriented towards the fresh air inlet. A fresh air transfer structure including a retractable adapter pipe is further used, allowing the adapter pipe to connect to the fresh air intake of the fan near the fresh air plate when extended to draw in fresh air, thus operating a fresh air mode. When fresh air is not needed, the adapter pipe retracts to clear the fresh air intake, allowing the fresh air intake to draw in indoor return air, thus operating an indoor circulation mode. The drawn-in air (fresh air and / or indoor return air) can be uniformly discharged through the air outlet after heat exchange or directly discharged. Therefore, the air conditioning device of this embodiment utilizes the existing fan cavity space and fan, achieving fresh air function without adding an additional fan. It does not require an additional fresh air fan or fresh air module, does not occupy internal or external space, maintains the original device thickness, does not increase costs, and provides a good user experience. It is particularly suitable for existing ultra-thin air conditioning devices.

[0018] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0020] Combination Figures 1 to 7 As shown, this embodiment of the present disclosure provides an air conditioning device, including a housing 10, a fan 20, and a fresh air transfer structure 30. The housing 10 is provided with a fan cavity 101. The housing 10 includes an air inlet plate 11 and a fresh air plate for constructing the fan cavity 101. An air inlet 110 is provided on the air inlet plate 11, and a fresh air inlet 103 is provided on the fresh air plate. The fan 20 is disposed in the fan cavity 101 to guide airflow; wherein, one air intake of the fan 20, located near the fresh air plate, faces the fresh air inlet 103, and this air intake serves as a fresh air intake 201. The fresh air transfer structure 30 includes a retractable transfer pipe 31; the transfer pipe 31 is disposed corresponding to the fresh air inlet 103; when the transfer pipe 31 is extended, it connects to the fresh air intake 201 of the fan located near the fresh air plate to draw in fresh air (such as...). Figure 1 As shown); when the transfer pipe 31 retracts, the fresh air intake 201 can draw in indoor return air (such as...). Figure 2 (As shown).

[0021] In the air conditioning device of this embodiment, a fresh air inlet 103 is opened on the fresh air plate of the fan cavity 101, and an air intake (as a fresh air intake 201) of the fan located near the fresh air plate is positioned towards the fresh air inlet 103. A fresh air transfer structure 30, including a retractable adapter pipe 31, is further used, so that when the adapter pipe 31 extends, it connects to the fresh air intake 201 of the fan located near the fresh air plate to draw in fresh air, operating in fresh air mode. When fresh air is not needed, the adapter pipe 31 retracts to clear the fresh air intake 201, allowing the fresh air intake 201 to draw in indoor return air, operating in indoor circulation mode. The drawn-in air (fresh air and / or indoor return air) is uniformly discharged through the air outlet 120 or directly discharged after heat exchange. Therefore, the air conditioning device of this embodiment utilizes the existing fan cavity space and fan, achieving fresh air function without adding an additional fan. It does not require an additional fresh air fan or fresh air module, does not occupy internal or external space, maintains the original equipment thickness, does not increase costs, and provides a good user experience. It is especially suitable for existing ultra-thin air conditioning equipment.

[0022] Understandably, when the adapter pipe 31 extends and connects to the fresh air intake 201, the port of the adapter pipe 31 is required to be sealed to the fresh air intake 201 to ensure that the fresh air intake 201 can draw in outdoor fresh air through the adapter pipe 31.

[0023] Understandably, the port of the adapter pipe 31 facing away from the fresh air intake 201 is used to connect to the fresh air duct to achieve connection with the outside.

[0024] In this embodiment of the disclosure, the fan 20 is used to guide the airflow. Depending on the actual application scenario, the fan 20 can guide the airflow to enter the room after heat exchange or flow directly into the room, which is not limited.

[0025] In some embodiments, the air conditioning device also includes a heat exchange chamber 102 inside the housing, and the exhaust port 2103 of the fan 20 is positioned toward the heat exchange chamber 102 to allow airflow to enter the heat exchange chamber 102 from the fan chamber 101 side.

[0026] In the air conditioning device of this disclosure embodiment, the arrangement of the fan chamber 101 and heat exchange chamber 102 within the housing 10 is not limited, and they can be arranged side by side in a front-to-back direction (see reference). Figure 3 and Figure 4 As shown in the diagram, the arrangement can also be sequential in the left-right direction, depending on actual needs. The front-back and left-right arrangements are determined based on the installed air conditioning equipment. It can be understood that a fan 20 is installed inside the fan chamber 101, and a heat exchanger 60 is installed inside the heat exchange chamber 102. The fan chamber 101 and the heat exchange chamber 102 are relatively independent. The heat exchange chamber 102 is connected to the exhaust port 2103 of the fan 20, so that airflow enters the heat exchange chamber 102 from the fan chamber 101 side.

[0027] The air conditioning equipment in this embodiment can be a ducted air conditioner, an indoor air conditioning unit, etc., and is not limited thereto, depending on actual needs.

[0028] In an optional example, combined Figure 3 and Figure 4 As shown, the housing 10 includes an air inlet plate 11, an air outlet plate 12, and two end plates (a first end plate 13 and a second end plate 14). The air inlet plate 11 and the air outlet plate 12 are arranged opposite to each other. The two end plates are respectively arranged at both ends of the air inlet plate 11 and connected to the air inlet plate 11 and the air outlet plate 12 on their respective sides. An air inlet 110 is provided on the air inlet plate 11, and an air outlet 120 is provided on the air outlet plate 12. A fan chamber 101 and a heat exchange chamber 102 are arranged inside the housing 10 along the air inlet plate 11 to the air outlet plate 12. One end or the end plate portion corresponding to both ends of the fan chamber 101 is a fresh air plate, that is, the portion of the first end plate 13 and / or the second end plate 14 corresponding to the fan chamber 101 serves as a fresh air plate.

[0029] Optionally, the housing 10 also includes a first partition 15, which is disposed between the air inlet plate 11 and the air outlet plate 12 to divide the space between the air inlet plate 11 and the air outlet plate 12 into a fan chamber 101 and a heat exchange chamber 102; a connecting port 150 is provided on the first partition, which is adapted to the exhaust port 2103 of the fan 20.

[0030] It is understood that the housing 10 also includes a top plate 17 and a bottom plate 18, which are disposed on the two ends of the frame formed by the air inlet plate 11, the air outlet plate 12, the first end plate 13 and the second end plate 14, to construct the inner cavity of the housing 10, and together with the first partition plate 15 to separate and form the fan cavity 101 and the heat exchange cavity 102.

[0031] In some embodiments, one or both end plates of the fan cavity are fresh air panels. This is determined based on the actual situation. When both end plates of the fan cavity serve as fresh air panels, fresh air inlets are opened on both panels, and each inlet is equipped with a corresponding transfer pipe 31. Simultaneous intake of fresh air from both sides increases the amount of fresh air drawn in and also improves the uniformity of mixing between fresh air and indoor return air in mixed fresh air mode.

[0032] In this embodiment, the fresh air inlet 103 can be a pre-reserved structure. That is, a position for the fresh air inlet 103 is reserved on the fresh air panel. When installing the air conditioning equipment, the fresh air inlet 103 is formed on-site by removing or creating the panel. Then, the fresh air transfer structure 30 is installed corresponding to the fresh air inlet 103. Optionally, fixing holes (e.g., screw holes) are provided around the reserved position of the fresh air inlet 103 for connecting the fresh air transfer structure 30.

[0033] In this embodiment of the disclosure, the retractable adapter pipe in the fresh air transfer structure 30 can be an integrally retractable telescopic pipe, such as a corrugated pipe; or it can be a partially retractable pipe, that is, including a fixed pipe section and a telescopic pipe section.

[0034] The expandable adapter can be made by deforming the pipe, such as a corrugated pipe; or it can be a sleeve-type expansion pipe structure, whichever is more specific and depends on the actual situation.

[0035] In some embodiments, the retractable adapter pipe includes a bellows. The pipe retractable structure is simple and easy to implement.

[0036] In some embodiments, the retractable adapter pipe includes a fixed pipe portion and a telescopic pipe portion connected together. The telescopic pipe portion can extend and retract relative to the fixed pipe portion to form a retractable adapter pipe. In this embodiment, the adapter pipe is configured to include a fixed pipe portion, which facilitates the installation of the adapter pipe. For example, the fixed pipe portion is fixed to the fresh air inlet 103 of the fresh air panel (e.g., the first end plate 13 and / or the second end plate 14), and also facilitates the control of the telescopic pipe portion.

[0037] Optionally, the fixed pipe section includes a first directional pipe; the telescopic pipe section includes a telescopic deformable pipe, one end of which is connected to one end of the first directional pipe, and the other end is used to connect to the fresh air intake 201; wherein the telescopic deformable pipe is coaxially connected to the first directional pipe.

[0038] Optionally, the fixed pipe section 311 also includes a second pipe, which is connected to the other end of the first pipe (the end away from the expansion joint), and the first pipe and the second pipe form an angle. This facilitates connection to the fresh air duct and increases installation convenience.

[0039] In some embodiments, combined with Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the retractable adapter pipe 31 includes a first pipe 311 (fixed pipe section) and a second pipe 312 (retractable pipe section) that are sleeved together. The first pipe 311 and the second pipe 312 can slide relative to each other. When the first pipe 311 is fixedly installed, the second pipe 312 can slide relative to the first pipe 311, forming the retractable adapter pipe 31. In this embodiment, the adapter pipe 31 consists of a sleeved first pipe 311 and a second pipe 312. The relative sliding of the second pipe 312 enables the extension or retraction of the second pipe 312, improving the displacement stability during the extension and retraction process. In this embodiment, the first pipe 311 is fixedly installed on the outside of the fresh air panel, and its internal channel corresponds to the fresh air inlet 103.

[0040] Optionally, the second pipe 312 is located inside the first pipe 311. When the adapter pipe 31 is in the retracted state, the second pipe 312 is located inside the first pipe 311 (e.g., Figure 6 As shown); when in the extended state, the second pipe 312 extends out of the first pipe 311 (as shown). Figure 5 (As shown).

[0041] Optionally, the first duct includes a first directional duct section and a second directional duct section, with the second duct section fitted over the first directional duct section; the first directional duct section and the second directional duct section form an angle. This facilitates connection to the fresh air duct and increases installation convenience.

[0042] Optionally, the angle between the first duct section and the second duct section is greater than 0° and less than 180°. The angle can be determined according to the installation environment of the air conditioning equipment, which facilitates the connection of external fresh air ducts.

[0043] In some embodiments, a mating sealing ring 33 is provided on the port of the retractable adapter pipe 31 that connects to the fresh air intake. Improving the sealing performance between the adapter pipe 31 and the fresh air intake 201 facilitates the intake of fresh air.

[0044] Understandably, the channel formed by the adapter pipe 31 in its extended state needs to remain sealed to ensure smooth airflow. In cases where the adapter pipe 31 includes a first pipe 311 and a second pipe 312, a circumferential sealing ring is provided at the second end of the second pipe 312 to seal the circumferential gap between the second pipe and the first pipe. This ensures a sealed channel is formed when the second pipe is extended.

[0045] In some embodiments, the fresh air transfer structure 30 further includes a drive mechanism 32, which can drive the transfer pipe 31 to extend or retract. The structure of the drive mechanism 32 is not limited, as long as it can output linear displacement.

[0046] Optionally, the drive mechanism includes a linear drive mechanism.

[0047] Optionally, combined Figure 5 and Figure 6 As shown, the drive mechanism 32 includes a drive motor 321, a gear 322, and a rack 323. The gear 322 is disposed at the rotary output end of the drive motor 321, and the rack 323 meshes with the gear 322. The rack 323 is disposed in the telescopic section of the telescopic adapter 31 or the second pipe 312. The drive motor 321 is fixedly disposed. In this embodiment, the gear and rack assembly converts the rotary output of the drive motor into a linear output, which is stable, reliable, and has high linearity.

[0048] The fixed setting of the drive motor 321 is not limited, as long as the gear 322 set at its rotation output end can mesh with the rack 323 set at the telescopic tube section of the adapter 31 or the second pipe 312 for transmission.

[0049] Optionally, the drive motor 321 is fixedly mounted on the fixed section of the retractable adapter pipe 31 or the first pipe 311. The fresh air adapter structure of this embodiment constitutes an integral structure, which is convenient for assembly.

[0050] Optionally, the fresh air transfer structure 30 also includes a guide rail structure, which is fixedly installed on the extension path of the retractable transfer pipe 31 to limit the extension and retraction of the retractable transfer pipe 31 along the guide rail structure, ensuring linear displacement during the extension and retraction process.

[0051] In an optional example, combined Figure 5 and Figure 6 As shown, the guide rail structure includes a guide rail and a guide groove 34. The guide rail is disposed on the first pipe or the second pipe, and correspondingly, the guide groove 34 is disposed on the second pipe or the first pipe; the guide rail is slidably disposed on the guide groove 34.

[0052] Optionally, the guide rail is disposed in the second pipe 312, and the guide groove 34 is formed in the first pipe 311.

[0053] Optionally, rack 323 is mounted on the guide rail. This integrated design reduces structural complexity and facilitates assembly.

[0054] In some embodiments, a guide groove 34 is formed at the first end of the first pipe 311 near the fresh air intake 201, and a rack 323 is disposed at the first end of the second pipe 312 near the fresh air intake 201; the rack 323 passes through the guide groove 34 and protrudes from the outer surface of the first pipe 311. In this embodiment, a gear 322 is located outside the first pipe 311 and meshes with the rack 323 protruding from the outer surface of the first pipe 311.

[0055] Optionally, the rack 323 is vertically arranged. In this embodiment, the toothed surfaces of the rack 323 face the side and protrude from the outer surface of the first pipe 311, facilitating meshing with the gear 322. In this embodiment, the rack 323 can also serve as a guide rail, ensuring linear displacement during the extension and retraction process.

[0056] In some embodiments, combined with Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the air conditioning equipment also includes an air valve 40 and / or a purification module (not shown). The air valve 40 is movably disposed on the fresh air intake path. When fresh air is not needed, the air valve 40 closes the fresh air intake path; when fresh air is needed, the air valve 40 opens the fresh air intake path. The purification module is disposed on the fresh air intake path and is used to purify the incoming outdoor fresh air.

[0057] In this embodiment, a damper 40 is installed on the fresh air intake path to open the path and, in conjunction with a retractable adapter pipe 31, introduce outdoor fresh air into the room. When fresh air is not needed, the damper 40 is closed to prevent outdoor foreign objects from entering. The purification module purifies the incoming indoor fresh air, improving indoor air quality.

[0058] In this embodiment, the location of the air valve 40 and / or the purification module is not limited and can be determined according to the actual situation, as long as it does not affect the extension and retraction of the retractable adapter pipe 31.

[0059] Optionally, the damper 40 is movably disposed at the fresh air inlet 103; the fresh air transfer structure 30 is located outside the fresh air panel; when the transfer pipe 31 extends, the damper 40 opens to allow the transfer pipe 31 to extend into the fan cavity (e.g., Figure 1 (As shown); when the transfer pipe 31 retracts, the air valve 40 closes the fresh air inlet (as shown). Figure 2 (As shown).

[0060] Optionally, the damper 40 is movably mounted on the adapter pipe 31; when the adapter pipe 31 extends, the damper 40 opens; when the adapter pipe 31 retracts, the damper 40 closes. The fresh air cut-off and conduction functions are integrated into the fresh air adapter structure 30, increasing the functionality of the fresh air adapter structure 30. In this embodiment, the damper 40 is located at the end of the adapter pipe 31 opposite to the fresh air intake 201. The end of the adapter pipe 31 opposite to the fresh air intake 201 generally does not undergo extension or retraction.

[0061] Optionally, the damper 40 is located at the fixed section of the transfer pipe 31 or the first pipe 311. For example... Figure 5 and Figure 6 As shown, the air valve 40 is installed in the first pipe 311 of the transfer pipe 31.

[0062] In some embodiments, combined with Figure 5 and Figure 6 As shown, the air conditioning equipment also includes a linkage mechanism 50, and an air valve 40 is movably disposed on the fresh air intake path (the placement is described in the aforementioned related content); the first linkage end 501 of the linkage mechanism 50 is connected to the adapter pipe 31 and moves as the adapter pipe 31 extends or retracts; the second linkage end 502 of the linkage mechanism 50 is connected to the air valve 40, so that the extension or retraction of the adapter pipe 31 can be used to realize the synchronous opening or closing of the air valve 40. In this embodiment, the opening or closing of the air valve 40 is linked with the extension or retraction of the adapter pipe 31 to improve synchronicity.

[0063] Optionally, the damper 40 is rotatably disposed at the end of the adapter pipe 31 opposite to the fresh air inlet 201 (the non-extensional section of the adapter pipe 31, such as a fixed section or the first pipe 311). The second linkage end 502 of the linkage mechanism 50 is connected to the rotating end of the damper 40. The linkage mechanism 50 can convert the linear displacement of the first linkage end 501 into the rotation of the second linkage end 502, thereby achieving the synchronous rotational opening or closing of the damper 40 by extending or retracting the adapter pipe 31. In this embodiment, the linkage mechanism 50 is configured such that the damper 40 synchronously rotates open when the adapter pipe 31 extends and synchronously rotates closes when it retracts.

[0064] In an optional example, the damper 40 is rotatably disposed within the fixed section of the adapter 31 or the first pipe 311. The first linkage end 501 of the linkage mechanism 50 is connected to the telescopic section of the adapter 31 or the second pipe 312, and the second linkage end 502 is connected to the rotating end of the damper 40. The linkage mechanism 50 can convert the linear displacement of the first linkage end 501 into the rotation of the second linkage end 502, and realize the synchronous rotational opening or rotational closing of the damper 40 by the extension or retraction of the adapter.

[0065] In some embodiments, when the fresh air transfer structure 30 includes a drive mechanism 32, and the drive mechanism 32 includes a drive motor 321, a gear 322 and a rack 323, the first linkage end 501 of the linkage mechanism 50 is connected to the rack 323.

[0066] In some embodiments, such as Figure 5 and Figure 6 As shown, the linkage mechanism 50 includes a pull rod 51 and a crank 52. The first end of the pull rod 51 is movably connected to the first end of the crank 52, and the pull rod 51 and the crank 52 form an angle. The second end of the pull rod 51 serves as the first linkage end 501, and the second end of the crank 52 serves as the second linkage end 502. The synchronous rotation of the air valve 40 is achieved by extending or retracting the adapter pipe 31. In this embodiment, the pull rod 51 and the crank 52, which are connected at an angle, connect the second end of the pull rod 51 to the telescopic tube section of the adapter pipe 31 or the second pipe 312, and the second end of the crank 52 is connected to the rotating end of the air valve 40. The second end of the pull rod 51 moves in a straight line, causing the second end of the crank 52 to rotate about the rotation axis of the air valve 40, thereby driving the air valve 40 to rotate.

[0067] It is understandable that the damper 40 is rotatably mounted within the transfer pipe 31, and the rotation axis of the damper 40 passes through the line of symmetry of the pipe cross-section of the transfer pipe 31. For example, when the pipe cross-section of the transfer pipe 31 is circular, the rotation axis of the damper 40 passes through the diameter of the pipe cross-section of the transfer pipe 31. Therefore, when the damper 40 is closed, it is perpendicular to the axis of the transfer pipe 31 to block the transfer pipe; when the damper 40 is open, it is parallel to the transfer pipe 31 to open the transfer pipe. The maximum rotation angle of the damper 40 when switching between the closed and open states is 90°.

[0068] When the fresh air transfer structure includes a damper 40 and a linkage mechanism 50, the displacement distance of the first linkage end 501 of the linkage mechanism 50 is adapted to the rotation angle of the damper 40. For example, the displacement distance of the first linkage end 501 of the linkage mechanism 50 is adapted to the rotation of the damper 40 between the axis perpendicular to the axis of the transfer pipe 31 and the axis parallel to the axis of the transfer pipe 31.

[0069] In some embodiments, the first linkage end 501 of the linkage mechanism 50 has an elongated hole 510, and a connecting post 34 is provided on the telescopic tube portion of the adapter pipe 31 or the second pipe 311, with the connecting post 34 passing through the elongated hole 510. In this embodiment, the length of the elongated hole 510 is greater than the size of the connecting post 34, so that the connecting post 34 only abuts against the inner wall of the end of the elongated hole 510 during a portion of the displacement stroke, thereby moving the first linkage end 501. This allows the air valve 40 to be fully opened when the adapter pipe 31 is connected to the fresh air intake 201, or the air valve 40 to be fully closed when the adapter pipe 31 is fully retracted.

[0070] That is, during the extension displacement, after the telescopic tube or the second pipe 312 extends a certain distance, the connecting post 34 abuts against the inner wall of the end of the elongated hole 510 near the fresh air intake 201 (defined as the first hole end 511), and during the remaining extension stroke, it drives the first linkage end 501 to move towards the fresh air intake 201, thereby opening the air valve 40. During the retraction displacement, after the telescopic tube or the second pipe 312 retracts a certain distance, the connecting post 34 abuts against the inner wall of the end of the elongated hole 510 away from the fresh air intake 201 (defined as the second hole end 512), and during the remaining retraction stroke, it drives the first linkage end 501 to move away from the fresh air intake 201, thereby closing the air valve 40.

[0071] It is understandable that the length of the elongated hole 510 corresponds to the idle displacement stroke of the connecting column 34, which satisfies the telescopic displacement of the adapter pipe 31 while realizing the rotational opening or closing of the air valve 40. Here, the idle displacement stroke refers to the stroke that does not drive the first linkage end 501 of the linkage mechanism 50 to move during the displacement process.

[0072] Optionally, the connecting post 34 is disposed on the rack 323 and located at the end of the rack 323 away from the mating port of the adapter pipe 31, that is, away from the fresh air intake 201.

[0073] In some embodiments, the line connecting the first linkage end 501 of the linkage mechanism 50 to the connection position of the transfer pipe 31 and the connection position of the rotating end of the air valve 40 to the transfer pipe 31 is parallel to the axial direction of the transfer pipe 31. In this embodiment, the linkage control of the linkage mechanism 50 is smoother and the control precision is better.

[0074] When an air conditioning unit includes a purification module, the purification function of the module is not limited and can be determined based on actual functional requirements. The functions of the purification module include, but are not limited to, filtration, removal of formaldehyde, sulfur dioxide, nitrogen oxides and other corrosive or toxic and harmful gases, and antibacterial properties.

[0075] In some embodiments, the purification module can be directly fixedly installed or detachably installed at the end of the adapter pipe 31 facing away from the fresh air intake 201. Integrating it into the fresh air conversion structure 30 increases the functionality of the fresh air conversion structure 30 and facilitates assembly. The end of the adapter pipe 31 facing away from the fresh air intake 201 includes a fixed pipe section or a first pipe 311.

[0076] Optionally, the purification module can be detachably mounted at the end of the adapter pipe 31 away from the fresh air intake 201 for easy replacement.

[0077] Optionally, an installation port is provided on the end of the adapter pipe 31 that is away from the fresh air intake 201, and the purification module is installed in the adapter pipe 31 through the installation port.

[0078] Optionally, when the air conditioning equipment includes both an air valve 40 and a purification module, the purification module and the air valve 40 are sequentially disposed in the fixed section of the transfer pipe 31 or the first pipe 311 along the direction towards the docking port of the transfer pipe 31. In this embodiment, the fresh air drawn in first flows through the purification module and then through the open air valve 40.

[0079] In this embodiment, the number and structure of the fans 20 are not limited and are determined according to the actual situation. It is understood that, in addition to the fresh air intake 201, the fan cavity 101 generally has one or more air intakes to ensure the airflow in the indoor return air mode.

[0080] In some embodiments, the fan 20 includes a first fan and / or a second fan, wherein the first fan is a fan with one air intake, and the second fan is a fan with two air intakes; when the first fan is provided in the fan cavity 101, the number of fans 20 is multiple; or, when the second fan is provided in the fan cavity 101, the number of fans 20 is one or more. This ensures that, in addition to the fresh air intake 201 facing the fresh air inlet, the fan cavity 101 also has other air intakes to guarantee airflow.

[0081] Optionally, when a first fan is installed in the fan cavity 101, two or more first fans can be installed in the fan cavity 101, or one first fan and one or more second fans can be installed. Optionally, the first fan installed near the fresh air panel is installed in the fan cavity 101 with its air intake facing the fresh air inlet 103, which is suitable for pure fresh air mode (see the subsequent control method section), and only the first fan is controlled to start and draw in fresh air. In this embodiment, a first fan can be installed at each of the two ends of the fan cavity 101, and the two first fans can draw in fresh air at the same time, realizing pure fresh air mode while also increasing the amount of fresh air introduced.

[0082] Optionally, when a second fan is provided in the fan cavity 101, one second fan may be provided in the fan cavity 101; or two or more second fans may be provided; or one second fan and one or more first fans may be provided. There are no limitations.

[0083] Optionally, a second fan is positioned near the fresh air intake panel. One air intake of the second fan faces the fresh air inlet 103, while the other air intake is located inside the fan chamber 101. This is suitable for mixed fresh air mode. When the second fan is started, both air intakes simultaneously draw in outdoor fresh air from the fresh air inlet 103 and indoor return air from the air intake panel 11, thus achieving mixed fresh air mode.

[0084] In an optional example, two second fans are provided in the fan cavity 101. One of the air inlets of the second fan located near the fresh air plate faces the fresh air inlet 103, and the other air inlet faces into the fan cavity 101. The other second fan is simply placed in the fan cavity 101.

[0085] In some embodiments, the fan 20 (referred to as the second fan) located near the fresh air panel includes a volute 21, which includes two opposing air intakes (a first air intake 2101 and a second air intake 2102) and an exhaust port 2103, wherein one air intake (e.g., the first air intake 2101) is positioned facing the fresh air panel.

[0086] Optionally, the exhaust port 2103 of the second fan forms a preset angle with the line connecting the two intake ports; the exhaust port 2103 is located between the two intake ports and faces the heat exchange chamber 102 (when heat exchange is not required, the exhaust port 2103 can be set directly towards the exhaust port), and one of the intake ports (e.g., the first intake port 2101) faces the fresh air panel. In this embodiment, the fan 20 located near the fresh air panel is a second fan, including a volute 21 with two oppositely arranged intake ports. One intake port (e.g., the first intake port 2101) faces the fresh air panel, and the other intake port (e.g., the second intake port 2102) is located inside the fan chamber 101. When the retractable adapter pipe 31 extends and connects to the first intake port 2101, it can draw in outdoor fresh air; when the adapter pipe 31 is in the retracted state, the first intake port 2101 can draw in indoor return air, realizing the switching of the operating mode.

[0087] Optionally, the exhaust port 2103 of the volute 21 is perpendicular to the line connecting the two intake ports. The fan 20 is installed in the fan cavity 101 in such a way that the line connecting the two intake ports is parallel to the length direction of the fan cavity 101 (e.g., the length direction of the air inlet plate 11).

[0088] It is understandable that the volute 21 contains structures such as a fan wheel and blades to drive airflow.

[0089] It is understandable that the fan is positioned within the fan space by extending the line connecting the two air inlets on the volute along the length of the fan cavity of the casing.

[0090] It is understood that the fan 20 also includes a fan motor 22, used to drive the impeller / blade (not shown) disposed within the volute 21 to rotate, thereby driving airflow. When multiple fans are disposed within the fan chamber 101, the multiple fans can be driven synchronously or independently, depending on the actual situation. Figure 3 and Figure 4 As shown, two fans 20 and one fan motor 22 are installed inside the fan cavity 101. The fan motor 22 has two drive ends, which are respectively connected to the fans 20 on both sides to drive the two fans 20 synchronously.

[0091] In some embodiments, combined with Figure 4 and Figure 7 As shown, a fresh air cavity 1011 is formed within the fan cavity 101 near the fresh air panel. A fresh air intake 201, facing the fresh air inlet 103, is located within the fresh air cavity 1011. In this embodiment, a portion of the air inlets on the air inlet panel 11 corresponding to the fresh air cavity 1011 forms the first air inlet, and the remaining air inlets serve as the second air inlet. When the adapter pipe 31 extends out and connects to the fresh air intake 201 to draw in fresh air, and other fan intakes within the fan cavity 101 simultaneously draw in indoor return air, the arrangement of the fresh air cavity 101 ensures that all indoor return air flows in through the second air inlet, without interfering with the fresh air intake of the fresh air intake 201.

[0092] It is understandable that a portion of the space near the fresh air panel within the fan cavity 101 is partitioned off to form a fresh air cavity 1011. The cavities outside the fresh air cavity 1011 also contain a fan 20 or a fan 20 intake port to ensure airflow in the indoor return air mode. For ease of description, the cavities within the fan cavity 101 other than the fresh air cavity 1011 are defined as the first fan cavity 1012. The portion of the air inlet corresponding to the first fan cavity 1012 is called the second air inlet.

[0093] When the fresh air cavity 1011 is formed by separation, the fan is set up in the same way as the above-mentioned related content. It is only necessary to set the fresh air inlet 201 of the fan that is close to the fresh air plate inside the fresh air cavity 1011.

[0094] It is understood that the volume of the fresh air cavity 1011 is not limited, as long as it forms an independent cavity to draw in fresh air. In some embodiments, the volume of the fresh air cavity 1011 is one-fifth to one-third of the volume of the fan cavity 101. Optionally, the volume of the fresh air cavity 1011 is one-fifth, one-quarter, or one-third of the volume of the fan cavity 101, which is not limited and is determined according to the actual situation.

[0095] In an optional example, the fan 20 positioned near the fresh air panel is a second fan. The exhaust port 2103 of the second fan forms a preset angle with the line connecting the two air intake ports. The exhaust port 2103 is located between the two air intake ports and faces the heat exchange chamber 102 (or, directly faces the air outlet 120, without heat exchange). One of the air intake ports (e.g., the first air intake port 2101) is located within the fresh air chamber 1011. In this embodiment, the fan 20 positioned near the fresh air panel is a second fan, including a volute 21 with two opposing air intake ports. When one air intake port (e.g., the first air intake port 2101) faces the fresh air panel and is located within the fresh air chamber 1011, the other air intake port (e.g., the second air intake port 2102) is located within the first fan chamber 1012.

[0096] Optionally, the housing 10 also includes a fresh air baffle 16, which is disposed at one or both ends of the fan cavity 101 and has a preset distance from the end plate on the corresponding side to form a fresh air cavity 1011; the fresh air baffle 16 is provided with an air intake hole, and the air intake of the fan 20 passes through the air intake hole into the fresh air cavity 1011.

[0097] Optionally, combined Figure 4 As shown, an isolation rib is provided on the outer peripheral surface of the volute 21 of the fan 20, which is located near the fresh air panel. The outer edge of the isolation rib is connected to the inner wall of the fan cavity 101, and the edge of the isolation rib is connected to the inner wall of the fan cavity 101, separating the fresh air cavity 1011. The isolation rib constitutes a fresh air baffle 16. In this embodiment, the fresh air baffle 16 is integrated into the volute 21 to facilitate the construction of the fresh air cavity 1011.

[0098] Optionally, combined Figure 7 As shown, the volute 21 includes an upper volute 211 and a lower volute 212. A first rib 161 is provided on the upper volute 211, and a second rib 162 is provided on the lower volute 212. This facilitates molding. When the upper volute 211 and the lower volute 212 are fastened together, the first rib 161 and the second rib 162 connect to form a fresh air baffle 16.

[0099] In this embodiment, the number and structure of the fans 20 are not limited and are determined according to the actual situation. It is understood that the fan cavity 101 also contains fans 20 or fan 20 air inlets in the cavity other than the fresh air cavity 1011 to ensure the airflow in the indoor return air mode or mixed fresh air mode.

[0100] In the air conditioning device of this embodiment, an air inlet 110 is provided on the air inlet plate 11, and an openable air inlet baffle can be provided on the air inlet 110. When it is necessary to draw in indoor return air, the air inlet baffle can be opened in a controlled manner.

[0101] In some embodiments, when a fresh air chamber 1011 is formed within the fan chamber 101, the air inlet baffles are correspondingly divided into a first air inlet baffle and a second air inlet baffle. The first air inlet baffle is closably disposed on a portion of the air inlet of the fresh air chamber 1011, and the second air inlet baffle is closably disposed on a portion of the air inlet of the first fan chamber 1012. This embodiment allows for separate control of the opening and closing of the fresh air chamber 1011 and the first fan chamber 1012. For example, in a mixed fresh air mode, controlling the first air inlet baffle to close and the second air inlet baffle to open reduces the mutual influence between the two chambers and also improves the aesthetic appearance.

[0102] In this embodiment, the structure of the air inlet baffle, the first air inlet baffle, and the second air inlet baffle is not limited, as long as it can enable the opening and closing of the air inlet.

[0103] Combination Figures 1 to 8 As shown, this disclosure provides a control method for an air conditioning device, including: S10, in response to the fresh air mode operation signal, controls the retractable adapter pipe 31 of the fresh air adapter structure 30 to extend and connect to the fresh air intake 201 of the fan located near the fresh air panel, starts the fan, and draws in outdoor fresh air to provide outdoor fresh air to the room (e.g., Figure 1 (As shown).

[0104] S20, in response to the indoor recirculation mode operation signal, controls the retractable adapter pipe 31 of the fresh air transfer structure 30 to retract or remain in the retracted state; starts the fan to draw in indoor return air. At this time, the air intake of the fan chamber 101 (including the fresh air chamber 1011 and the first fan chamber 1012) is indoor return air, which is the normal air conditioning mode (such as indoor return air). Figure 2 (As shown).

[0105] The control method for air conditioning equipment provided in this embodiment of the present disclosure can be used to easily switch between indoor circulation mode (normal air conditioning mode) and fresh air mode by controlling the extension or retraction of the retractable adapter pipe 31 of the fresh air adapter structure 30. The control method is simple.

[0106] It is understandable that there is no order restriction between steps S10 and S20.

[0107] It is understood that the control method of this disclosure embodiment only relates to the control method of air intake mode switching, and conventional operation control methods can be used for the cooling and heating operation of air conditioning equipment.

[0108] In some embodiments, an openable and closable air inlet damper is provided on the air inlet 110 of the air conditioning equipment; step S10 includes: S11, in response to a pure fresh air mode operation signal, controlling the retractable adapter pipe 31 of the fresh air transfer structure 30 to extend and connect to the fresh air intake 201 of the fan located near the fresh air panel, controlling the air inlet damper to close the air inlet 110, and starting the fan 20 near the fresh air panel to operate in pure fresh air mode; S12, in response to a mixed fresh air mode operation signal, controlling the retractable adapter pipe 31 of the fresh air transfer structure 30 to extend and connect to the fresh air intake 201 of the fan located near the fresh air panel, controlling the air inlet damper to open the air inlet 110, and starting all fans 20 to operate in mixed fresh air mode. In this embodiment, the fresh air mode includes pure fresh air mode and mixed fresh air mode, which is determined according to actual needs.

[0109] Optionally, if an openable air inlet damper is provided on the air inlet 110 of the air conditioning equipment, step S20 further includes controlling the air inlet damper to open the air inlet 110. The air intake of the fan cavity 101 is indoor return air, which is a normal air conditioning mode.

[0110] When the air inlet baffle is divided into a first air inlet baffle and a second air inlet baffle, in step S11, the first air inlet baffle and the second air inlet baffle are controlled to close. In step S12, the first air inlet baffle is controlled to close or remain closed, and the second air inlet baffle is controlled to open.

Optionally, the device may further include a communication interface 72 and a bus 73. The processor 70, communication interface 72, and memory 71 can communicate with each other via the bus 73.
