Description

Technical Field

[0001] The present invention relates to the field of air conditioning, in particular to an embedded indoor unit and an air conditioning system having the same. Background Art

[0002] An air conditioning system generally refers to equipment that manually adjusts and controls parameters such as temperature, humidity, and air flow within a conditioned space (such as a building or structure). An air conditioning system typically consists of an indoor unit installed within the conditioned space and an outdoor unit located outdoors. Indoor units come in a variety of styles, including wall-mounted, cabinet-mounted, and embedded. Embedded indoor units (also known as "embedded units") offer numerous advantages, including a small footprint, elegant appearance, and uniform air delivery. Consequently, embedded air conditioning systems are gaining popularity among users.

[0003] Like other air conditioning systems, embedded air conditioning systems typically consist of a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, all interconnected by refrigerant piping to form a refrigeration circuit. In cooling mode, the indoor heat exchanger in an embedded air conditioning system acts as an evaporator. Its surface temperature is typically low, causing some moisture in the air to condense as it passes over it.

[0004] To prevent condensation from flowing into the conditioned room, existing embedded indoor units typically include a drain pan on their housing to collect the condensation. Furthermore, a drainage device (e.g., a drain pipe, a drain pump, etc.) is typically installed on the drain pan to drain the condensation promptly. However, due to the uneven surface of the drain pan and the uneven distribution of condensation within the pan, the drainage device struggles to completely drain the condensation. Consequently, some condensation may remain in the pan, where it can breed bacteria and produce odors, significantly reducing the user experience.

[0005] In order to solve the technical problem that the condensed water in the water receiving pan is difficult to completely remove, a lot of research and attempts have been made in the prior art. Among them, one control method is to control the air conditioning system to run the heating mode after the air conditioning system ends the cooling process, and use the hot air generated by the air conditioning system to dry the condensed water remaining in the water receiving pan. In this control method, in order to improve the drying efficiency and to prevent hot and humid air from entering the conditioned space from the air outlet and reducing the user experience, the air outlet needs to be closed. In this embedded indoor unit, in order to promptly discharge the hot and humid air generated by drying the condensed water, it is necessary to add a dehumidification pipe for dehumidification to the water receiving pan. In addition, in order to prevent cold air (or hot air) from flowing out of the dehumidification pipe during normal use of the embedded indoor unit and reducing the cooling (or heating) efficiency, it is also necessary to add a component to control the opening and closing of the dehumidification pipe. Therefore, the structure of the embedded indoor unit is relatively complex and the manufacturing cost is high, and there is room for improvement.

[0006] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0007] In order to solve the above-mentioned problems in the prior art, namely, to solve the technical problems of the complex structure and high manufacturing cost of the embedded indoor unit in the prior art, the present invention provides an embedded indoor unit. The embedded indoor unit includes: a housing, a water receiving tray for accommodating condensed water is formed inside the housing, a plurality of air outlets spaced apart from each other are formed at the bottom of the housing, and a wind guide plate for controlling the opening and closing of each air outlet is provided on each air outlet; at least one dehumidification assembly, each dehumidification assembly including a dehumidification pipe arranged on the water receiving tray and enabling air communication between the water receiving tray and the external environment, and a baffle matched with the dehumidification pipe to control the opening and closing of the dehumidification pipe; and a driving device, the driving device being arranged between each dehumidification assembly and the corresponding wind guide plate and configured to respectively control the rotation of the wind guide plate and the baffle, wherein when the wind guide plate is controlled by the driving device to rotate to open the air outlet, the baffle closes the dehumidification pipe, and when the baffle is controlled by the driving device to rotate to open the dehumidification pipe, the wind guide plate closes the air outlet.

[0008] The embedded indoor unit of the present invention includes a housing, at least one dehumidification assembly, and a drive device. A water collection tray for condensed water is formed within the housing. A plurality of spaced-apart air outlets are formed at the bottom of the housing. Each air outlet is provided with an air guide plate that can be controlled to open and close. Each dehumidification assembly includes a dehumidification pipe and a flap that cooperates with the dehumidification pipe to control its opening and closing. The dehumidification pipe is disposed on the water collection tray, allowing the water collection tray to establish air communication with the external environment. Therefore, after evaporation, condensed water remaining in the water collection tray can be smoothly discharged into the external environment through the dehumidification pipe rather than being retained within the water collection tray, effectively preventing the residual condensed water from breeding bacteria and generating odor within the water collection tray. The drive device is disposed between each dehumidification assembly and the corresponding air guide plate. The rotation of both the air guide plate and the flap can be controlled by a single drive device, thereby simplifying the structure of the embedded indoor unit of the present invention and reducing manufacturing costs. Furthermore, when the air guide plate is rotated by the drive device to open the air outlet, the flap is controlled to close the dehumidification pipe. It is understandable that when the air-conditioning system is operating normally, cold air (or hot air) flows into the conditioned space from the open air outlet. At this time, the dehumidification pipe is closed by the baffle to prevent cold air (or hot air) from flowing out of the dehumidification pipe, thereby ensuring the efficiency of cooling (or heating). Accordingly, when the baffle is controlled by the driving device to rotate to open the dehumidification pipe, the air guide plate is configured to be controlled to close the air outlet. It is understandable that when the air-conditioning system is turned off, the air outlet is closed by the air guide plate, which can prevent the humid air generated by the evaporation of condensed water from flowing into the conditioned space from the air outlet. At the same time, the opening of the dehumidification pipe can smoothly discharge the humid air, thereby improving the dehumidification efficiency. Through the above-mentioned setting, alternating control of the air outlet and the dehumidification pipe (that is, one component is open and the other component is closed) can be achieved, thereby simplifying the control logic and reducing the control cost.

[0009] In the preferred technical solution of the above-mentioned embedded indoor unit, the drive device includes: a dual-axis drive motor; a first incomplete gear and a second incomplete gear, which are respectively fixed to a corresponding one of the two drive shafts of the dual-axis drive motor, and the first incomplete gear has a first toothed portion and a first toothless portion extending along its circumference, and the second incomplete gear has a second toothed portion and a second toothless portion extending along its circumference, wherein the first toothed portion corresponds to the second toothless portion, and the first toothless portion corresponds to the second toothed portion. By providing a dual-axis motor, the purpose of controlling two components with one motor can be conveniently achieved. Furthermore, the purpose of alternating control can also be achieved by using the first incomplete gear and the second incomplete gear that cooperate with each other.

[0010] In the preferred technical solution of the embedded indoor unit, an incomplete internal gear sleeve is formed on the corresponding air guide plate to match the first incomplete gear. The cooperation between the first incomplete gear and the incomplete internal gear sleeve enables the driving device to intermittently control the rotation of the air guide plate.

[0011] In the preferred technical solution of the above-mentioned embedded indoor unit, each of the dehumidification components further includes: a steering shaft having a steering gear matched with the second incomplete gear and a rotating shaft extending into the water receiving tray along the central axis of the steering gear; a fixed bracket arranged in the water receiving tray, comprising a connecting plate extending vertically inward from the vertical side wall of the water receiving tray, and the baffle having a first end and an opposite second end rotatably fixed to the connecting plate; a reset elastic member arranged on the baffle and capable of applying a pre-applied external force to the baffle so that it rests against the dehumidification pipe; and a flexible connector having a first connecting end that can be wound around the rotating shaft and a second connecting end fixed to the second end. Through the mutual cooperation of the above-mentioned components, the baffle can be controlled to move in a direction away from the dehumidification pipe to open the dehumidification pipe, and to move in a direction close to the dehumidification pipe to close the dehumidification pipe.

[0012] In the preferred technical solution of the above-mentioned embedded indoor unit, the reset elastic member is arranged between the baffle and the connecting plate, or the reset elastic member is arranged between the baffle and the dehumidification pipe. Through the above-mentioned arrangement, the product types can be enriched to meet the diverse needs of users.

[0013] In the preferred technical solution of the above-mentioned embedded indoor unit, the rotation axis is arranged on the side of the connecting plate away from the baffle. Compared to arranging the rotation axis on the side of the connecting plate closer to the baffle, arranging the rotation axis farther from the baffle allows the baffle to rotate at a greater angle, making it easier for moist air to enter the dehumidification pipe. Furthermore, with fewer components near the dehumidification pipe, moist air encounters less obstruction during flow, further improving dehumidification efficiency.

[0014] In the preferred technical solution of the above-mentioned embedded indoor unit, a through hole is provided on the connecting plate to allow the flexible connector to pass therethrough. Providing the through hole on the connecting plate to allow the flexible connector to pass therethrough allows the flexible connector to be constrained by the through hole when it is wound or unwound by the rotating shaft, thereby preventing the flexible connector from becoming entangled or knotted.

[0015] In the preferred technical solution of the above-mentioned embedded indoor unit, a hinge shaft is provided on the vertical edge of the connecting plate away from the fixed plate, and a sleeve is provided on the first end to be sleeved over the hinge shaft. The cooperation between the hinge shaft and the sleeve allows a secure and stable pivotal connection to be formed between the baffle and the connecting plate.

[0016] In the preferred technical solution of the above-mentioned embedded indoor unit, the embedded indoor unit further includes a drain pipe connected to the water receiving pan and capable of draining the condensed water, and the moisture drain pipe is a bypass pipe formed on the drain pipe. Providing the moisture drain pipe as a bypass pipe formed on the drain pipe can make the structure of the embedded indoor unit of the present invention more compact and further reduce manufacturing costs.

[0017] In the preferred technical solution of the above-mentioned embedded indoor unit, a sealing member capable of sealing the moisture drain pipe is provided on the baffle. The provision of the sealing member can improve the sealing performance of the moisture drain pipe.

[0018] To address the aforementioned problems in the prior art, namely, the complex structure and high manufacturing costs of embedded indoor units, the present invention further provides an air conditioning system. The air conditioning system includes any of the embedded indoor units described above. By employing any of the embedded indoor units described above, the air conditioning system of the present invention can promptly discharge moist air generated by evaporation and condensation within the water tray via a dehumidification pipe, thereby improving dehumidification efficiency. Furthermore, the air conditioning system of the present invention utilizes a single drive device to simultaneously control both the air deflector and the baffle, simplifying the structure and reducing manufacturing costs.

[0035] Figure 1 FIG is a schematic structural diagram of an embodiment of the embedded indoor unit of the present invention. Figure 1 As shown, in one or more embodiments, the embedded indoor unit 1 of the present invention includes but is not limited to components such as a shell 10, a dehumidification component 20 and a drive device 30. The shell 10 is formed in one piece by an injection molding process using ABS, PP or other suitable resin materials. The shell 10 has a roughly square bottom (not shown in the figure). A roughly square grille-like air intake port (not shown in the figure) is provided in the middle position of the bottom. Four air outlets 12 (only one is shown in the figure) surrounding the air intake port are formed around the bottom. Each air outlet 12 is provided with an air guide plate 13 that can adjust the air outlet angle and control its opening and closing. Each air guide plate 13 has an air guide plate body 131 extending in a direction parallel to the corresponding air outlet 12, and a first shaft 132 and a second shaft 133 located on both sides of the air guide plate body 131, so that the air guide plate body 131 can be rotatably fixed to the shell 10.

Alternatively, the number of dehumidification assemblies 20 and the drive device 30 can be set to two, three, or four according to actual needs.

[0036] Continue to see Figure 1 A water receiving tray 11 for receiving condensed water is formed inside the shell 10. The water receiving tray 11 has vertical side walls 111 extending vertically upward from the bottom of the shell 10 to form a roughly square shape. In one or more embodiments, the water receiving tray 11 is configured to be integrally formed with the shell 10 to simplify the manufacturing process. Alternatively, the water receiving tray 11 can also be processed separately from the shell 10 and then fixedly connected. In one or more embodiments, a drainage device is provided on the water receiving tray 11 to drain the condensed water in time. The drainage device includes a drainage motor and a drainage pipe 40 connected to the water receiving tray 11. The drainage motor includes but is not limited to a stepper motor, a servo motor, etc. The drainage pipe 40 can be integrally formed using ABS, PP or other suitable resin materials through an injection molding process. See Figure 3 and Figure 4 The drain pipe 40 has a water inlet 41 connected to the water receiving pan 11 and an opposite water outlet 42. The water outlet 42 is configured to be connected to the external environment through a pipeline so as to smoothly discharge the condensed water from the water receiving pan 11.

[0037] Figure 2 FIG. 1 is a schematic diagram of the structure of an embodiment of the driving device of the embedded indoor unit of the present invention. Figure 2 As shown, in one or more embodiments, the driving device 30 has a dual-axis drive motor 31. In one or more embodiments, the dual-axis drive motor 31 is configured to achieve forward rotation and reverse rotation through a controller (not shown in the figure), thereby driving the air guide plate 13 to open forward, close reversely, and rotate forward and reversely, and can also conveniently control the opening and closing of the dehumidification pipe in the dehumidification component 20. The dual-axis drive motor 31 includes but is not limited to a stepping motor, a servo motor, etc. Based on Figure 2As shown, the dual-shaft drive motor 31 has a first drive shaft 311 extending leftward along its central axis and a second drive shaft 312 extending rightward along its central axis. A first incomplete gear 313 is provided at the end of the first drive shaft 311, and a second incomplete gear 314 is provided at the end of the second drive shaft 312. The first incomplete gear 313 has a first toothed portion 3131 and a first toothless portion 3132 extending along its circumference. In one or more embodiments, the first incomplete gear 313 is configured to be sleeved on the first shaft 132 of the air deflector 131, and the first shaft 132 is provided with an incomplete gear sleeve 1321 that can mate with the first incomplete gear 313. It should be pointed out that when the first toothed portion 3131 of the first incomplete gear 313 is engaged with the toothed portion (not shown in the figure) in the incomplete gear sleeve 1321, the air guide plate 13 can be controlled to rotate; when the first toothless portion 3132 of the first incomplete gear 313 is engaged with the toothless portion (not shown in the figure) in the incomplete gear sleeve 1321, the air guide plate 13 stops rotating.

[0038] Continue to see Figure 2 In one or more embodiments, the second incomplete gear 314 has a second toothed portion 3141 and a second toothless portion 3142 extending along its circumference. The second incomplete gear 314 is configured to mate with the steering gear 251 in the dehumidification assembly 20 to intermittently control the rotation of the steering gear 251. In addition, the first toothed portion 3131 corresponds to the second toothless portion 3142, and the first toothless portion 3132 corresponds to the second toothed portion 3141. In other words, when the first incomplete gear 313 and the incomplete gear sleeve 1321 engage with each other to drive the air deflector 13 to rotate, the second incomplete gear 314 and the steering gear 251 disengage from each other, and the steering gear 251 remains stationary. When the second incomplete gear 314 and the steering gear 251 engage with each other to drive the steering gear 251 to rotate, the first incomplete gear 313 and the incomplete gear sleeve 1321 disengage from each other, and the air deflector 13 remains stationary.

[0040] Figure 4 2 is a second structural schematic diagram of an embodiment of a drainage assembly of a built-in indoor unit of the present invention; Figure 5 yes Figure 4 FIG. 1 is an enlarged schematic diagram of part A of an embodiment of a drainage assembly of an embedded indoor unit of the present invention. Figure 3 and Figure 4As shown, in one or more embodiments, the dehumidification assembly 20 includes a dehumidification pipe 21, a baffle 22 for controlling the opening and closing of the dehumidification pipe 21, a fixing bracket 23 fixed to the vertical side wall 111 of the water receiving tray 11, a flexible connector 24, a steering shaft 25, and a return spring 26. In one or more embodiments, the dehumidification pipe 21 is a connecting pipe arranged on the vertical side wall 111, allowing air communication between the water receiving tray 11 and the external environment. Alternatively, the dehumidification pipe 21 is a bypass pipe 43 integrally formed with the drain pipe 40, thereby further streamlining the structure and reducing manufacturing costs.

[0041] Continue to see Figure 3 and Figure 4 In one or more embodiments, the baffle 22 is a roughly rectangular plate-like structure. In one or more embodiments, the baffle 22 can be made of suitable metal materials such as stainless steel and galvanized sheet, so that it has good mechanical properties and corrosion and rust resistance. Alternatively, the baffle 22 can also be made of PP or other suitable resin materials to reduce manufacturing costs. In one or more embodiments, a seal (not shown in the figure) is also provided on the baffle 22 to enhance the sealing between the baffle 22 and the dehumidification pipe 21 to prevent condensed water from leaking from the connection. The baffle 22 has a first end 221 and a second end 222 that are opposite. Based on Figure 4 In the orientation shown, the first end 221 is the right end of the baffle 22, and the second end 222 is the left end of the baffle 22. Figure 5 As shown, in one or more embodiments, a shaft sleeve 2211 is provided on the first end 221 so that the baffle 22 can be rotatably fixed to the fixing bracket 23. In one or more embodiments, the flexible connector 24 is fixed to the second end 222 of the baffle 22, so that the second end 222 of the baffle 22 can rotate around the first end 221 under the drive of the flexible connector 24, thereby moving toward the direction close to the moisture drain pipe 21 to close the moisture drain pipe 21, or moving toward the direction away from the moisture drain pipe 21 to open the moisture drain pipe 21.

[0042] like Figure 3 shown, and based on Figure 3In one or more embodiments, the fixing bracket 23 includes a fixing plate 231 fixed to the vertical side wall 111 and a connecting plate 232 extending vertically inward (i.e., toward the interior of the water receiving tray 11) from the left end of the fixing plate 231. Alternatively, the connecting plate 232 may be configured to extend vertically inward from the right end of the fixing plate 231. The fixing bracket 23 may be integrally formed using an injection molding process using ABS, PP, or other suitable resin materials. In one or more embodiments, the fixing plate 231 is a generally rectangular plate-like structure. Alternatively, the fixing plate 231 may be configured in a square, trapezoidal, or other suitable shape. The fixing plate 231 is provided with a first mounting hole 2311 and a second mounting hole 2312 spaced apart vertically from each other. The second mounting hole 2311 and the second mounting hole 2312 are generally circular through-holes, allowing the fixing bracket 23 to be securely and stably mounted to the vertical side wall 111 by engaging with mounting members (e.g., screws, bolts, etc.). In one or more embodiments, the connecting plate 232 is also a substantially rectangular plate-shaped structure. Alternatively, the connecting plate 232 can also be configured as a rectangle, a trapezoid or other suitable shapes. Figure 4 and Figure 5 As shown, in one or more embodiments, a hinge shaft 23211 is formed on the vertical edge 2321 of the connecting plate 232 away from the fixed plate 231, which can be matched with the shaft sleeve 2211 on the blocking piece 22, so that a firm and stable pivot connection can be formed between the blocking piece 22 and the connecting plate 232. Figure 3 As shown, in one or more embodiments, the connecting plate 232 is further provided with a through hole 2322 that allows the flexible connector 24 to pass therethrough, so that the flexible connector 24 can be constrained within the through hole 2322. In one or more embodiments, the fixing bracket 23 is further provided with a reinforcing plate 233. The reinforcing plate 233 is configured to extend vertically inward from the lower end of the fixing plate 231 to enhance the rigidity and strength of the fixing bracket 23 and extend its service life.

[0043] Continue to see Figure 3 and Figure 4 In one or more embodiments, the flexible connector 24 is a nylon rope. Alternatively, the flexible connector 24 may be other suitable flexible connectors such as a polyester rope, a cotton rope, an elastic rope, etc. The flexible connector 24 has a first connecting end 241 and a second connecting end 242 relative to each other. The first connecting end 241 is fixed to the rotating shaft 252 of the steering shaft 25, and the second connecting end 242 is fixed to the second end 222 of the baffle 22. In one or more embodiments, the flexible connector 24 is configured to pass through the through hole 2322 on the connecting plate 232, so that the flexible connector 24 can be constrained in the through hole 2322 to prevent it from being entangled and knotted.

[0044] Continue to see Figure 3 and Figure 4In one or more embodiments, the steering shaft 25 has a steering gear 251 connected to each other and a rotating shaft 252 extending outward along the central axis of the steering gear 251. The steering gear 251 and the rotating shaft 252 are configured to be integrally formed using forged steel, cast steel or other suitable metal materials to enhance their rigidity and strength. In one or more embodiments, a plurality of conical gear teeth (not marked in the figure) distributed along the circumference of the steering gear 251 are formed. The conical gear teeth are configured to match the second incomplete gear 314, so that when the second toothed portion 3141 of the second incomplete gear 314 engages with the conical gear teeth, the rotating shaft 252 can be driven to rotate, and when the second toothless portion 3142 is opposite to the conical gear teeth, the rotating shaft 252 remains stationary. Continue to see Figure 1 The rotating shaft 252 is configured to extend from the steering gear 251 into the water receiving tray 11, and the rotating shaft 252 is substantially perpendicular to the vertical side wall 111 of the water receiving tray 11. In other words, the vertical side wall 111 is formed with an axial hole (not shown) that allows the rotating shaft 252 to pass therethrough, so that the rotating shaft 252 is constrained in the axial hole to obtain a stable structure.

[0045] Figure 6 1 is a structural diagram of a first embodiment of a drainage assembly of a built-in indoor unit of the present invention;

[0046] Figure 7 1 is a structural diagram of a second embodiment of a drainage assembly of a built-in indoor unit of the present invention; Figure 8 1 is a schematic structural diagram of a third embodiment of a drainage assembly of a built-in indoor unit of the present invention; Figure 9 FIG. 1 is a structural diagram of a fourth embodiment of a drainage assembly of an embedded indoor unit of the present invention. Figure 6 and Figure 7 As shown, in one or more embodiments, the rotation shaft 252 is arranged on a side of the connecting plate 232 away from the baffle 22. Figure 8 and Figure 9 As shown, in one or more embodiments, the rotation axis 252 is disposed on the side of the connecting plate 232 near the baffle 22. It should be noted that, compared to being disposed on the side of the connecting plate 232 near the baffle 22, arranging the rotation axis 252 farther from the baffle 22 allows the baffle 22 to rotate at a greater angle, making it easier for moist air to enter the dehumidification pipe 21. Furthermore, with fewer components near the dehumidification pipe 21, the moist air encounters less obstruction during flow, further improving dehumidification efficiency. Furthermore, this arrangement allows for a wider range of product types to meet diverse user needs.

[0047] Continue to see Figure 3-Figure 6 and Figure 8In one or more embodiments, a reset elastic member 26 is further provided between the connecting plate 232 and the baffle 22. The reset elastic member 26 may be a spring, rubber, or other suitable elastic member. By providing the reset elastic member 26 between the connecting plate 232 and the baffle 22, the baffle 22 can be smoothly reset, that is, returned to the position against the dehumidification pipe 21. At this time, the reset elastic member 26 can also apply a certain pre-thrust on the baffle 22, so that the baffle 22 is more firmly and stably against the dehumidification pipe 21, thereby further enhancing the sealing effect. See Figure 7 and Figure 9 In one or more alternative embodiments, the resetting elastic member 26 may also be disposed between the baffle 22 and the moisture drain pipe 21. In this case, the resetting elastic member 26 may exert a certain pre-tension on the baffle 22, so that the baffle 22 rests more firmly and stably against the moisture drain pipe 21.

[0048] In order to solve the technical problems of the complex structure and high manufacturing cost of the embedded indoor unit in the prior art, the present invention provides an air-conditioning system (not shown in the figure). In one or more embodiments, the air-conditioning system includes the embedded indoor unit 1 described in any of the above embodiments and an outdoor unit unit (not shown in the figure) interconnected with the embedded indoor unit 1 through a refrigerant pipeline to form a refrigeration circuit. The outdoor unit unit includes but is not limited to components such as a compressor, a four-way valve, an outdoor heat exchanger, and an outdoor fan. The embedded indoor unit 1 is also provided with components such as an expansion valve, an indoor heat exchanger, and an indoor fan (not shown in the figure), so that the air-conditioning system of the present invention has both cooling and heating functions.

[0049] When the air-conditioning system of the present invention is idle, the air outlet 12 is closed by the air guide plate 13. At this time, the baffle 22 moves away from the dehumidification pipe 21 to open the dehumidification pipe 21. The water collecting tray 11 can be connected to the external environment through the dehumidification pipe 21. The residual condensed water in the water collecting tray 11 can be discharged from the dehumidification pipe 21 in time after evaporation. When the air-conditioning system of the present invention is turned on, the dual-axis drive motor 31 starts to rotate (the direction of rotation at this time is defined as "forward"). At this time, the second toothed portion 3141 on the second incomplete gear 314 engages with the steering gear 251 and controls the flexible connector 24 to loosen from the rotating shaft 252. Driven by the reset elastic member 26, the baffle 22 moves toward the direction close to the dehumidification pipe, thereby closing the dehumidification pipe 21. At the same time, the first toothless portion 3132 of the first incomplete gear 313 cooperates with the toothless portion of the incomplete gear sleeve 1321, and the air guide plate 13 continues to close the air outlet 12.

[0050] After the baffle 22 completely abuts against the dehumidification pipe 21 to close it, the dual-axis drive motor 31 continues to rotate forward, causing the second toothless portion 3142 of the second incomplete gear 314 to face the steering gear 251, i.e., the second incomplete gear 314 is disengaged from the steering gear 251. At the same time, the first toothed portion 3131 of the first incomplete gear 313 engages with the toothed portion of the incomplete gear sleeve 1321, driving the air guide plate 13 to rotate, thereby opening the air outlet 12. It should be noted that when the air guide plate 13 is rotating, the baffle 22 always abuts against the dehumidification pipe 21, keeping the dehumidification pipe 21 closed, thereby effectively preventing the cold air (or hot air) generated by the air conditioning system during cooling (or heating) from flowing out of the dehumidification pipe 21 and reducing the cooling (or heating) efficiency.

[0051] When the air conditioning system of the present invention is shut down, the dual-axis drive motor 31 rotates in the reverse direction under the control of the controller, driving the air deflector 13 to close the air outlet 12. Once the air outlet 12 is completely closed by the air deflector 13, the dual-axis drive motor 31 continues to rotate in the reverse direction, causing the first toothed portion 3131 of the first incomplete gear 313 to disengage from the toothed portion of the incomplete gear sleeve 1321. The first toothless portion 3132 of the first incomplete gear 313 engages with the toothless portion of the incomplete gear sleeve 1321, and the air deflector 13 remains stationary, continuing to close the air outlet 12. Simultaneously, the second toothed portion 3141 of the second incomplete gear 314 engages with the steering gear 251, controlling the flexible connector 24 to wrap around the rotating shaft 252. The flexible connector 24 generates an external force pulling the baffle 22, gradually overcoming the pre-thrust or pre-tension force applied by the return spring 26, thereby causing the baffle 22 to rotate away from the dehumidification pipe 21, thereby opening the dehumidification pipe 21. In one or more embodiments, when the dehumidification pipe 21 is fully opened, the dual-axis drive motor 31 stops rotating and the air conditioning system is shut down.

[0052] In one or more embodiments, the air conditioning system of the present invention also performs a dehumidification process after the cooling process ends, in order to drain as much condensed water as possible from the water pan 11. Specifically, after the cooling process ends, the drive device 30 controls the air guide plate 13 to rotate to close the air outlet and controls the baffle 22 to rotate away from the dehumidification pipe 21 to open the dehumidification pipe 21. The air conditioning system then operates in heating mode, using the hot air generated by the air conditioning system to accelerate the evaporation rate of the condensed water remaining in the water pan 11. The hot and humid air generated by the evaporation of the condensed water can then be promptly discharged from the open dehumidification pipe 21, further improving dehumidification efficiency.

[0053] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
