[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0056] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0057] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0058] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0059] Currently, fresh air modules are typically installed independently below the heat exchange module. The heat exchange module includes a heat exchanger, a heat exchange channel, and a heat exchange fan. The heat exchange fan directs air flow through the heat exchanger and out through the outlet of the heat exchange channel. The fresh air module includes a fresh air channel and a fresh air fan located within the channel. The fresh air fan is responsible for transporting air from the fresh air channel to the upper heat exchange channel; that is, the fresh air fan and the heat exchange fan operate in series. This fresh air function has a relatively complex structure, which is not conducive to controlling the production cost of air conditioners.

[0060] In view of this, the present invention proposes an air conditioner, please refer to... Figures 1 to 6 In one embodiment of the present invention, the air conditioner includes:

[0061] The housing 10 is provided with a first air outlet 11, a second air outlet 12, a main air inlet 13, a fresh air inlet 14, and an air duct 15. The air duct 15 includes a first air duct 151 and a second air duct 152 that are independent of each other. The first air duct 151 connects the main air inlet 13 and the first air outlet 11, and the second air duct 152 connects the main air inlet 13 and the second air outlet 12.

[0062] The wind turbine assembly includes a first wind turbine 21 disposed in the first wind duct 151 and a second wind turbine 22 disposed in the second wind duct 152;

[0063] A heat exchanger 30 is disposed in the housing 10, and is located on the air inlet side of the first air duct 151 and the air inlet side of the second air duct 152; and

[0064] The air intake control module includes an air guide 40 that is movable relative to the housing 10. The air conditioner has a first heat exchange mode and a fresh air mode. In the first heat exchange mode, the air guide 40 is in a first position and isolates the second air duct 152 and the fresh air inlet 14. The first air duct 151 and the second air duct 152 are both connected to the main air inlet 13. In the fresh air mode, the air guide 40 is in a second position and connects the second air duct 152 and the fresh air inlet 14, and isolates the second air duct 152 and the main air inlet 13. The first air duct 151 is connected to the main air inlet 13.

[0065] In this invention, the movable air guide 40 allows either the main air inlet 13 or the fresh air inlet 14 to be connected to the second air duct 152, enabling the second air duct 152 and the second impeller 22 to participate in both the first heat exchange mode and the fresh air mode. In other words, this application configures the heat exchange fan and fresh air fan of the prior art into the same structure. Compared to the prior art's use of independent and series-connected heat exchange fans and fresh air fans, this application has a simpler structure and can reduce production costs.

[0066] Specifically, optionally, in the first heat exchange mode, the heat exchanger 30 is controlled to operate, the air guide 40 is controlled to be in the first position, and both the first impeller 21 and the second impeller 22 are controlled to operate. Thus, the air flowing through the heat exchanger 30 is supplied to the outside through the first air duct 151 and the second air duct 152 respectively. That is, both the first air outlet 11 and the second air outlet 12 supply air to the outside, which helps improve the heat exchange efficiency of the air conditioner. Of course, in other embodiments, only one of the first impeller 21 and the second impeller 22 can operate. It can be understood that when the first impeller 21 or the second impeller 22 operates alone, only its corresponding air outlet (the first air outlet 11 or the second air outlet 12) will supply air to the outside, while the other air outlet will not supply air, which helps reduce the energy consumption of the air conditioner.

[0067] It is understood that the drive structure of the first wind turbine 21 and the second wind turbine 22 can take many forms. For example, in one embodiment, the wind turbine assembly further includes a first motor 23 driving the first wind turbine 21 and a second motor 24 driving the second wind turbine 22. That is, two independent motors are used to drive the operation of the first wind turbine 21 and the second wind turbine 22 respectively. This simplifies the structure of the wind turbine assembly and facilitates the arrangement of the first wind turbine 21 and the second wind turbine 22. Of course, in other embodiments, the first wind turbine 21 and the second wind turbine 22 can share the same motor. Specifically, the motor has two output shafts. The first output shaft is connected to the first wind turbine 21 through a first clutch, and the second output shaft is connected to the second wind turbine 22 through a second clutch, so that the individual operation of the first wind turbine 21 and the second wind turbine 22 can be controlled separately.

[0068] Although the embodiment shown in the accompanying drawings is an indoor unit of a split-type air conditioner, it does not mean that the technical solution of the present invention is limited to split-type air conditioners. It is understood that the technical solution of the present invention can also be applied to other types of air conditioner products such as unitary air conditioners, and this application does not make specific limitations in this regard. For ease of writing, the following description will use a split-type air conditioner, in which the first air outlet 11, the second air outlet 12, and the main air inlet 13 on the casing 10 are all connected to the indoor space, and the fresh air inlet 14 is connected to the outdoor space.

[0069] Please refer to Figures 4 to 7 In one embodiment, the fresh air inlet 14 and the air inlets 152a of the second air duct 152 are spaced apart along a first direction, and the air guide 40 is movable along the first direction between the second air duct 152 and the fresh air inlet 14. That is, by translating, the air guide 40 allows the second air duct 152 to selectively conduct between the first air inlet and the fresh air inlet 14, which is not only simple in structure but also easy to implement. Of course, in other embodiments, the air guide 40 can also be rotatably mounted on the housing 10.

[0070] Please refer to Figures 6 to 10 In one embodiment, the air guide 40 includes a hood 41. The hood 41 has a hood opening 41a corresponding to the air inlet 152a of the second air duct 152, and an air passage opening 41b corresponding to the fresh air inlet 14. The air passage opening 41b is connected to the hood opening 41a. In the first position, the side wall of the hood 41 blocks the fresh air inlet 14, and the hood opening 41a and the air inlet 152a of the second air duct 152 are spaced apart in the first direction. In the second position, the air passage opening 41b is connected to the fresh air inlet 14, and the hood opening 41a is connected to the air inlet 152a of the second air duct 152. Thus, the structure of the hood 41 is simple and easy to implement. Of course, in some embodiments, the air guide 40 may include a baffle, with the main air inlet 13 and the fresh air inlet 14 both located on the side of the baffle away from the second air duct 152. The baffle can move along the first direction and selectively block the main air inlet 13 or the fresh air inlet 14.

[0071] Please refer to Figure 4 , Figure 5 and Figure 10In one embodiment, the housing 10 is further provided with a water receiving tray 16, and the heat exchanger 30 is disposed above the water receiving tray 16. The water receiving tray 16 has a clearance hole 161 corresponding to the fan shroud 41, and the fan shroud 41 is movably inserted through the clearance hole 161 in a vertical direction. The fan shroud 41 has an upper end plate 411, which covers the clearance hole 161 in the first position. That is, in this embodiment, the first direction is configured as a vertical direction. Thus, when the air guide 40 is in the first position, the upper end plate 411 covers the clearance hole 161 and serves as part of the water receiving tray 16, thereby preventing condensate generated on the heat exchanger 30 from falling into the clearance hole 161, thus protecting the component structure located below the clearance hole 161. Of course, in other embodiments, the fan shroud 41 may not have an upper end plate 411 that can cover the clearance hole 161.

[0072] In one embodiment, the upper end plate 411 has a first side edge 412 extending beyond the side wall of the hood 41. In the first position, the first side edge 412 abuts against the end face of the clearance hole 161. Thus, the first side edge 412 not only provides better coverage of the clearance hole 161 but also restricts the hood 41 from further downward movement within the clearance hole 161. Of course, in other embodiments, the first side edge 412 may be omitted, and the outer contour of the upper end plate 411 may be adapted to the size of the clearance hole 161, with the upper end plate 411 housed within the clearance hole 161 in the first position.

[0073] Please refer to Figure 13 In one embodiment, the bottom of the drip tray 16 is provided with a drain outlet 162, and the upper end plate 411 extends at an angle toward the drain outlet 162. This facilitates the flow of condensate dripping onto the upper end plate 411 toward the drain outlet 162 and avoids the problem of condensate accumulating on the upper end plate 411. Of course, in other embodiments, the upper end plate 411 may also be horizontally arranged, and its upper surface may be coated with a hydrophobic coating.

[0074] Please refer to Figures 7 to 10In one embodiment, the hood opening 41a is located on the side wall of the hood 41 near the second air duct 152, and extends downward from the lower side of the upper end plate 411 and penetrates the lower end face of the hood 41. The air passage 41b is located on the lower end face of the hood 41, and the fresh air inlet 14 is located on the side of the hood 41 away from the second air duct 152. That is, the fresh air inlet 14 and the air inlet 152a of the second air duct 152 are located on opposite sides of the hood 41; the side wall of the hood 41 away from the second air duct 152 can cover the fresh air inlet 14 in the first position, and can expose the fresh air inlet 14 in the second position, so that the fresh air inlet 14 can communicate with the air passage 41b on the lower end face. Thus, the structure of the hood 41 is simple and easy to implement. Of course, in other embodiments, the hood opening 41a and the air vent 41b may both be located on the side of the hood 41 near the second air duct 152 and spaced apart from top to bottom. The fresh air inlet 14 may be located on the side of the hood 41 near the second air duct 152. In this case, the side wall of the hood 41 located between the hood opening 41a and the air vent 41b may cover the fresh air inlet 14 in the first position.

[0075] In one embodiment, a baffle 153 is provided on the upper edge of the air inlet 152a of the second air duct 152, and at the second position, the baffle 153 abuts against the upper end plate 411. This reduces the amount of fresh air escaping from the gap between the hood 41 and the second air duct 152, and allows fresh air to flow into the second air duct 152 as much as possible, and be directed from the air outlet of the second air duct 152 to indoor areas farther from the air conditioner. Of course, in other embodiments, the baffle 153 may not be provided.

[0076] Please refer to Figures 10 to 13 In one embodiment, the air intake control module further includes a drive module 50 that drives the air guide 40 to move along the first direction. Specifically, the drive module 50 is electrically connected to the main control circuit board (processor) of the air conditioner to selectively drive the fan cover 41 to a first position or a second position according to different operating modes of the air conditioner. This improves the intelligence and ease of use of the air conditioner. Of course, in other embodiments, the drive module 50 may not be provided. The user can manually drive the fan cover 41 to move relative to the housing 10 and switch the fan cover 41 between the first position and the second position. Specifically, a pull rope may be provided at the upper end of the fan cover 41. One end of the pull rope passes through the top surface of the housing 10 and is provided with a pull ring for gripping. The user can hold the pull ring to pull the fan cover 41 to move the fan cover 41 upward to the second position. At this time, the pull ring can be tied to the housing 10. When the pull force on the pull ring is released, the fan cover 41 will move downward to the first position under its own weight.

[0077] In one embodiment, the drive module 50 includes a drive element 51 and a transmission assembly 52. ​​The transmission assembly 52 includes a gear 521 and a rack 522 that mesh and transmit power. The gear 521 drives a shaft connected to the drive element 51, and the rack 522 is disposed on the shroud 41 and extends along the first direction. Thus, the meshing transmission of the gear 521 and rack 522 improves the smoothness and stability of the shroud 41's movement. Specifically, the drive element 51 can be configured as an electric motor, a pneumatic motor, or a hydraulic motor. Of course, in some embodiments, the drive module 50 can also be configured as a linear motor, a cylinder, or a hydraulic cylinder. For example, the free end of the telescopic rod of the linear motor is disposed on the shroud 41, allowing the shroud 41 to move under the drive of the telescopic rod. In other embodiments, the drive module 50 can also be configured as a ball screw device.

[0078] Please refer to Figures 8 to 10 In one embodiment, an air inlet channel 164 communicating with the clearance hole 161 is provided below the water receiving tray 16. The fresh air inlet 14 is located in the air inlet channel 164. The driving member 51 is located on the outer side of the air inlet channel 164, and the gear 521 is located on the inner side of the air inlet channel 164. The rotating shaft of the driving member 51 extends into the air inlet channel 164 and connects to the gear 521. Thus, by placing the driving member 51 on the outer side of the air inlet channel 164, the interference of the driving assembly on the airflow within the air inlet channel 164 can be reduced. Optionally, in this embodiment, the same transmission assembly 52 includes two gears 521. The first gear 521 is sleeved on the rotating shaft of the driving member 51, and the second gear 521 is meshed between the first gear 521 and the rack 522. Of course, in some embodiments, only one gear 521 may be provided. In other embodiments, both the driving member 51 and the gear 521 may be located within the air inlet channel 164.

[0079] Please refer to Figures 10 to 13 In one embodiment, two transmission components 52 are provided, and the two transmission components 52 are respectively disposed on opposite sides of the hood opening 41a. This further improves the smoothness and stability of the movement of the hood 41. Optionally, two drive members 51 are also provided, one drive member 51 driving the gear 521 of one transmission component 52, and the other drive member 51 driving the gear 521 of the other transmission component 52. Of course, in some embodiments, there may be only one transmission component 52, or three or more. In other embodiments, there are two transmission components 52 and only one drive member 51, with a distribution gear 521 on the shaft of the drive member 51, and the gears 521 of the two transmission components 52 meshing on opposite sides of the distribution gear 521.

[0080] Please refer to Figures 1 to 6In one embodiment, the air inlet 151a of the first air duct 151, the air inlet 152a of the second air duct 152, and the fresh air inlet 14 are distributed sequentially from top to bottom. The heat exchanger 30 extends in the vertical direction and corresponds to the air inlet 152a of the second air duct 152 and the air inlet 151a of the first air duct 151. The main air inlet 13 extends in the vertical direction and corresponds to the heat exchanger 30. The hood 41 moves up and down within the interval between the heat exchanger 30 and the second air duct 152. Thus, in fresh air mode, when the fan cover 41 is in the second position and covers the air inlet 152a of the second air duct 152, under the negative pressure generated by the operation of the first fan wheel 21, the air flowing from the upper end of the autonomous air inlet 13 to the upper end of the heat exchanger 30 directly flows into the first air duct 151 corresponding to the upper end of the heat exchanger 30, while the air flowing from the lower end of the autonomous air inlet 13 to the lower end of the heat exchanger 30 also flows upward and merges with the airflow above before entering the first air duct 151. That is, in fresh air mode, the overall structure of the heat exchanger 30 still participates in heat exchange, so that the air conditioner does not reduce the heat exchange efficiency of the heat exchanger 30 while introducing fresh air, thereby improving the user experience of the air conditioner. Furthermore, by having one heat exchanger 30 simultaneously responsible for the heat exchange of the first air duct 151 and the second air duct 152, the heat exchange mode control logic of the air conditioner is relatively simple, and it is beneficial to simplify the structure and weight of the refrigerant piping inside the casing 10.

[0081] Of course, in some embodiments, the heat exchanger 30 may include a first heat exchange section and a second heat exchange section that are separately arranged. The first heat exchange section is arranged at the top and corresponds to the air inlet 151a of the first air duct 151, and the second heat exchange section corresponds to the air inlet 152a of the second air duct 152. Further optionally, the first heat exchange section and the second heat exchange section may also be configured to operate independently, that is, the first heat exchange section works alone, the second heat exchange section works alone, or both work simultaneously. Of course, in other embodiments, the main air inlet 13 may include a first air inlet and a second air inlet spaced apart in the vertical direction, with the first air inlet corresponding to the air inlet 151a of the first air duct 151 and the second air inlet corresponding to the air inlet 152a of the second air duct 152. Further optionally, when the heat exchanger 30 includes a separately configured first heat exchange section and a second heat exchange section, the end face of the air inlet 151a of the first air duct 151 directly abuts against the inner end face of the first air inlet, and the first heat exchange section is located within the first air duct 151; the end face of the air inlet 152a of the second air duct 152 directly abuts against the inner end face of the second air inlet, and the second heat exchange section is located within the second air duct 152. In other embodiments, the air inlets 151a of the first air duct 151 and the air inlets 152a of the second air duct 152 may be arranged side-by-side in the horizontal direction.

[0082] Please refer to Figure 3 , Figure 4 and Figure 11In one embodiment, the second air duct 152 includes a volute section 154 and an upper extension section 155 connected to each other. The volute section 154 has an air inlet, and the upper extension section 155 extends upward from the volute section 154 and has an air outlet. The first air duct 151 extends in the front-rear direction and is at least partially located within the upper extension section 155. The second impeller 22 is configured as a centrifugal impeller, and the first impeller 21 is configured as an axial flow impeller. Thus, by setting the centrifugal impeller, the air outlet of the second air duct 152 can be positioned higher. In fresh air mode, the fresh air introduced from the fresh air inlet 14 can be delivered to areas of the indoor space farther from the air conditioner through the higher air outlet, thereby promoting the circulation of fresh air in more areas of the indoor space. Furthermore, the air inlet 152a of the second air duct 152 can be positioned lower to be closer to the fresh air inlet 14, which helps to reduce the length of the hood 41 in the first direction. Of course, in other embodiments, the first air duct 151 and the second air duct 152 may both extend in the front-to-back direction, the first impeller 21 and the second impeller 22 may both be configured as axial flow impellers, the first air duct 151 may be set at the top, and the fresh air inlet 14 may be set below the second air duct 152.

[0083] In one embodiment, the sidewall of the upper extension 155 is provided with a rotatable first louver 156, which surrounds the outer periphery of the air outlet of the first air duct 151. The first louver 156 is provided with a plurality of air passage holes 157 spaced apart, which connect the inner and outer sides of the upper extension 155. Thus, the airflow within the second air duct 152, such as fresh air, can also flow through the first louver 156 to the first air outlet 11, and this fresh air can surround the outer periphery of the airflow exiting from the first air duct 151, thereby enriching the airflow patterns of the air conditioner. It can be understood that when the first louver 156 is fully open, the fresh air flow into the first air outlet 11 from the second air duct 152 is at its maximum; when the first louver 156 is fully closed, the fresh air flow into the first air outlet 11 from the second air duct 152 is at its minimum, and due to the presence of the air passage holes 157, the first air outlet 11 can still receive a certain flow of fresh air.

[0084] It is worth mentioning that the air conditioner of this application also has a windless mode. In this mode, the first louver 156 is completely closed, the first fan wheel 21 is not working, and the second fan wheel 22 is working. In this way, the airflow in the air conditioner is mainly transported to the high and far areas of the indoor space through the second air outlet 12, and a small amount of airflow flows out from the air passage 157 and the first air outlet 11, which can significantly reduce the airflow directly blowing on the human body, thereby achieving the effect of windlessness. It can be understood that the windless mode can be freely combined with other air outlet modes such as the first heat exchange mode and the fresh air mode. For example, when the user turns on the first heat exchange mode and the windless mode at the same time, the control fan cover 41 moves to the first position, the first louver 156 is completely closed, the first fan wheel 21 is not working, and the second fan wheel 22 is working, and the heat exchanger 30 is working. Then, the air flowing through the heat exchanger 30 basically flows into the second air duct 152, and then most of it flows to the second air outlet 12 and a small part flows to the first air outlet 11.

[0085] Please refer to Figures 1 to 3 Specifically, in this embodiment of the invention, optionally, the fresh air inlet 14 and the main air inlet 13 are both located on the rear side of the housing 10. The second air outlet 12 includes a front upper air outlet 121 and a top air outlet 122 that are connected to each other. The front upper air outlet 121 and the air outlet of the first air duct 151 are both located on the front side of the housing 10, with the front upper air outlet 121 located above the first air outlet 11 and the top air outlet 122 located on the top surface of the housing 10. In this way, the airflow in the second air duct 152 is thrown further away through the front upper air outlet 121 and the top air outlet 122, which is beneficial to the airflow in the indoor space; while the air outlet of the first air duct 151 can meet the user's need for airflow to directly blow on the human body, which is beneficial to the rapid cooling or heating of the user's surrounding space. Of course, the air outlet of the first air duct 151, the air outlet of the second air duct 152, the fresh air inlet 14 and the main air inlet 13 can also be provided on other sides or the top surface of the housing 10. For example, the fresh air inlet 14 can be provided on the left or right side of the housing 10. This application does not make any specific limitations.

[0086] Alternatively, the housing 10 is further provided with a rotatable second louver 17, which is located at the first air outlet 11 and in front of the first louver 156. The blades and rotation axis of the second louver 17 extend in the left and right directions to adjust the airflow direction of the first air outlet 11.

[0087] Please refer to Figures 4 to 10In one embodiment, the air guide 40 further includes a slide rail 42 disposed on the air shroud 41. The heat exchanger 30 includes a mounting base 32 and a heat exchanger body 31 disposed on the mounting base 32. The mounting base 32 is provided with a guide rail (not shown in the figure) corresponding to the slide rail 42, and the slide rail 42 is slidably disposed on the guide rail along the first direction. In this way, the cooperation between the slide rail 42 and the guide rail can improve the smoothness and stability of the air shroud 41 moving in the vertical direction. Of course, in some embodiments, the guide rail can also be disposed on the side of the air inlet 152a of the second air duct 152, or on the inner wall surface of the housing 10, with the guide rail extending downward to the water receiving tray 16. In other embodiments, the guide rail and slide rail 42 may not be provided, and a sliding gap is formed between the second air duct 152 and the mounting base 32, with the side edge of the air shroud 41 slidably clamped in the sliding gap.

[0088] Please refer to Figure 4 and Figure 5 In one embodiment, the guide rail extends downward into the water receiving tray 16, and at the first position, the upper end face of the slide rail 42 is located above the water receiving tray 16. Thus, when the slide rail 42 moves downward along with the fan cover 41 to the first position, the upper end of the slide rail 42 also has a certain length of structure higher than the upper end plate 411, maintaining a good connection with the lower end structure of the guide rail. This reduces the risk of the slide rail 42 accidentally detaching from the guide rail and improves the operational stability of the fan cover 41. Of course, in other embodiments, the upper end face of the slide rail 42 may be flush with the upper side of the upper end plate 411, and the lower end of the guide rail may extend downward below the clearance hole 161.

[0089] Please refer to Figure 10 In one embodiment, two slide rails 42 are provided, with the two slide rails 42 respectively located on opposite sides of the cover opening 41a. That is, two guide rails are also provided, with the two guide rails respectively located on opposite sides of the mounting base 32. In this way, the smoothness and stability of the sliding of the hood 41 can be further improved. Of course, in other embodiments, only one slide rail 42 may be provided, or three or more slide rails 42 may be provided.

[0090] Please refer to Figures 8 to 11In one embodiment, the housing 10 further includes an air inlet channel 164 located below the second air duct 152. The hood 41 moves up and down within the air inlet channel 164. The air inlet channel 164 includes a secondary air inlet 163 and a fresh air inlet 14. The hood 41 in the second position simultaneously connects the secondary air inlet 163, the fresh air inlet 14, and the air inlet 152a of the second air duct 152. Specifically, the secondary air inlet 163 connects to the indoor space and is used to introduce indoor air into the second air duct 152. Thus, in the fresh air mode, since the hood 41 simultaneously connects the secondary air inlet 163, the fresh air inlet 14, and the air inlet 152a of the second air duct 152, indoor air and fresh air can be introduced into the second air duct 152 simultaneously. Therefore, the fresh air can exchange heat and mix with the indoor air within the second air duct 152, making the fresh air temperature closer to the indoor temperature and improving the user experience. Of course, in other embodiments, the secondary air inlet 163 may not be provided.

[0091] It is understandable that the indoor air introduced through the main air inlet 13 will flow through the heat exchanger 30 and undergo heat exchange, while the indoor air introduced through the secondary air inlet 163 will not flow through the heat exchanger 30. The secondary air inlet 163 plays the role of creating an internal circulation of indoor air.

[0092] Please refer to Figures 6 to 10In one embodiment, the air conditioner further includes a first baffle 61 movably disposed in the air inlet channel 164. When the air shroud 41 is in the second position, the first baffle 61 can isolate or connect the secondary air inlet 163 and the air inlet 152a of the second air duct 152. Specifically, when the first baffle 61 isolates the secondary air inlet 163 and the air inlet 152a of the second air duct 152, only the fresh air introduced by the fresh air inlet 14 can flow into the second air duct 152 along the air shroud 41. This is a single fresh air mode. Since the fresh air fails to mix with the indoor air and exchange heat, the airflow temperature output from the second air duct 152 is closer to the outdoor temperature. When the first baffle 61 connects the secondary air inlet 163 and the air inlet 152a of the second air duct 152, both the indoor air introduced by the secondary air inlet 163 and the fresh air introduced by the fresh air inlet 14 can flow into the second air duct 152 along the air shroud 41. Specifically, the opening degree of the first baffle 61 is set to 0 when it functions as a barrier, and 100% when it functions as a fully conductive element. Therefore, the opening degree when it functions as a partial conductor includes 30%, 50%, or 70%, etc. It can be understood that as the opening degree increases, the cross-sectional area of ​​the air inlet channel 164 at the first baffle 61 increases, allowing more indoor air to flow from the secondary air inlet 163 into the second air duct 152, thus increasing the flow rate of indoor air mixed with the fresh air. In this way, by setting the first baffle 61, the flow rate of indoor air introduced from the secondary air inlet 163 can be flexibly adjusted, which is beneficial for flexibly adjusting the temperature of the fresh air.

[0093] In one embodiment, the air conditioner further includes a second baffle 62 movably disposed in the air inlet channel 164. The second baffle 62 can isolate or connect the fresh air inlet 14 and the air inlet 152a of the second air duct 152. Thus, by adding the second baffle 62, the intake airflow can be adjusted, thereby achieving more flexible and diverse fresh air modes. Specifically, similar to the first baffle 61, the opening degree of the second baffle 62 is set to 0 when it acts as an isolation function, and 100% when it acts as a complete connection function. When the opening degree of the second baffle 62 is 0, an internal circulation mode can be realized, that is, at this time, the fan cover 41 is only used to guide the indoor air introduced by the secondary air inlet 163 to the second air duct 152.

[0094] Specifically, when the indoor space has not been ventilated for a long time and it is inconvenient to open the windows, the rapid fresh air mode can be used. In this mode, the control hood 41 is moved to the second position, and the first baffle 61 and the second baffle 62 are both opened to the maximum degree, so as to simultaneously open the fresh air inlet 14, the secondary air inlet 163 and the air inlet 152a of the second air duct 152. The first impeller 21 and the second impeller 22 are both working, thereby accelerating the indoor air circulation to the maximum extent while supplementing the outdoor fresh air, achieving the purpose of rapid ventilation. At this time, the heat exchanger 30 is not working.

[0095] In the air conditioner's regular heating or cooling mode, i.e., the first heat exchange mode, the fan shroud 41 is in the first position to maximize the heat exchange efficiency of the heat exchanger 30. When the user has been using the air conditioner in the first heat exchange mode for an extended period and needs to change the indoor air, they can switch to the comfort fresh air mode. In this mode, the fan shroud 41 is moved to the second position, and the second baffle 62 is opened, controlling the heat exchanger 30, the first fan wheel 21, and the second fan wheel 22 to all operate. The user can freely set the heat exchange mode and preset temperature, for example, setting the cooling mode with a preset temperature of 18°C. It can be understood that the comfort fresh air mode is a second heat exchange mode, distinct from the first heat exchange mode, with higher heat exchange efficiency in the first mode. Thus, the air conditioner can continuously cool or heat the indoor air while introducing fresh air to replenish the indoor space and reduce indoor temperature fluctuations. Optionally, in the comfort fresh air mode, the first baffle 61 can also be opened, for example, to 50%, to accelerate the circulation of indoor air. Alternatively, in the Comfort Fresh Air mode, if the user also turns on the No Wind mode, the second louver 17 is controlled to swing upward so that the airflow from the first air outlet 11 is tilted upward, thereby preventing the airflow from the first air outlet 11 from blowing directly on the human body and achieving a No Wind effect.

[0096] Of course, the fresh air modes in this application are not limited to the single fresh air mode, rapid fresh air mode and comfortable fresh air mode mentioned above. Those skilled in the art can set more fresh air modes according to user needs.

[0097] When the user activates the internal circulation mode, the control hood 41 moves to the second position and the second impeller 22 operates. The control also closes the second baffle 62 and opens the first baffle 61 to prevent fresh air from entering the second air duct 152, and allows indoor air to circulate through the secondary air inlet 163, the hood 41, the second air duct 152, and the second impeller 22. At this time, the heat exchanger 30 and the first impeller 21 can operate or not.

[0098] When the user simultaneously activates both the internal circulation mode and the windless mode, the control shroud 41 moves to the second position, the first impeller 21 is deactivated while the second impeller 22 is activated, the second baffle 62 is closed while the first baffle 61 is opened, the first louver 156 is completely closed, and the heat exchanger 30 is deactivated. Only indoor air flowing in from the secondary air inlet 163 is guided into the second air duct 152, with most flowing to the second air outlet 12 and a small portion flowing to the first air outlet 11. It can be understood that when the windless mode is deactivated while the internal circulation mode is retained, both the heat exchanger 30 and the first impeller 21 are activated to achieve indoor air heat exchange and maintain a stable indoor temperature.

[0099] Please refer to Figure 8In one embodiment, the air inlet channel 164 includes a first channel section 165 and a second channel section 166 arranged side-by-side in the horizontal direction and connected at their upper ends. The second channel section 166 is located away from the second air duct 152. The fan shroud 41 moves up and down within the first channel section 165. The secondary air inlet 163 is located on the side wall of the first channel section 165, and the fresh air inlet 14 is located on the side wall of the second channel section 166. The first baffle 61 rotates to open and close the first channel section 165, and the second baffle 62 rotates to open and close the second channel section 166. Specifically, the drive motors of the first baffle 61 and the second baffle 62 are both electrically connected to the main control circuit board of the air conditioner to selectively open and close the first baffle 61 and the second baffle 62 according to different operating modes of the air conditioner. In this way, not only is the structure simple, but the fresh air and indoor air can be pre-mixed at the upper ends of the first channel section 165 and the second channel section 166, which is beneficial for temperature regulation of the mixed airflow output from the second air duct 152. Of course, in other embodiments, the first baffle 61 can also be a sliding open and close first channel segment 165, and the second baffle 62 can be a sliding open and close second channel segment 166.

[0100] Please refer to Figures 8 to 10 In one embodiment, the air conditioner further includes a filter module 63 inserted into the secondary air inlet 163. The filter module 63 is equipped with filter sheets, which can filter indoor air before introducing it into the second air duct 152, thereby improving indoor air quality. Furthermore, the filter module 63 is detachably installed in the secondary air inlet 163, allowing users to easily replace the filter module 63 to maintain its good filtration performance. Of course, in other embodiments, the filter module 63 may not be included.

[0101] Please refer to Figure 14 , Figure 14This is a schematic diagram of an air conditioner structure in the hardware operating environment of an embodiment of the present invention. The air conditioner may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard. Optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0102] Those skilled in the art will understand that Figure 14 The structure shown does not constitute a limitation on the air conditioner and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0103] like Figure 14 As shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and an air conditioner control program. Figure 14 In the air conditioner shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the air conditioner of the present invention can be set in the air conditioner. The air conditioner calls the air conditioner control program stored in the memory 1005 through the processor 1001 and executes the air conditioner control method provided in the embodiment of the present invention.

[0104] Please refer to Figure 15 The present invention also proposes an air conditioner control method, applied to the aforementioned air conditioner. In the first embodiment of the air conditioner control method of the present invention, the air conditioner control method includes steps S110 and S120, as follows:

[0105] Step S110: Receive the signal to turn on the fresh air mode.

[0106] Specifically, the fresh air mode refers to the air conditioner using a fresh air inlet that connects to the outdoor space to introduce fresh outdoor air, thereby replenishing the fresh air content in the indoor space and improving indoor air quality. The signal to activate the fresh air mode can come from a user command or be automatically generated by the air conditioner's processor during program execution.

[0107] Step S120: Control the air intake control module to the second position.

[0108] Specifically, upon receiving a signal to activate the fresh air mode, if the air guide is already in the second position, it does not need to move. If the air guide is in the first position, it is controlled to move from the first position to the second position. The air guide in the second position can connect the second air duct and the fresh air inlet, and can also isolate the second air duct from the main air inlet. The first air duct is connected to the main air inlet. Thus, fresh air introduced from the fresh air inlet can flow into the second air duct through the air guide, thereby achieving the fresh air function.

[0109] In this invention, a movable air guide allows the main air inlet and the fresh air inlet to be selectively connected to the second air duct, enabling the second air duct and the second impeller to participate in both the first heat exchange mode and the fresh air mode. In other words, this application configures the heat exchange fan and fresh air fan of the prior art into a single structure. Compared to the prior art's use of independent and series-connected heat exchange fans and fresh air fans, this application has a simpler structure and can reduce production costs.

[0110] In the second embodiment of the air conditioner control method of the present invention, based on the aforementioned first embodiment, 16, the air conditioner control method as described in claim 15, is characterized in that the fresh air mode includes a fast fresh air mode and a comfortable fresh air mode. Before the step of receiving the fresh air mode activation signal, the air conditioner control method further includes steps S101 to S103, as follows:

[0111] Step S101: Detect the indoor air quality of the indoor space.

[0112] In this embodiment, the air quality detection items include carbon dioxide concentration; that is, the indoor air quality includes carbon dioxide concentration. Specifically, the measured value of carbon dioxide concentration in the indoor space can be directly collected by a carbon dioxide sensor installed on the air conditioner, or obtained through the Internet of Things (IoT) from carbon dioxide concentration data collected by other devices in the indoor space. Of course, in other embodiments, the air quality detection items can also be other parameters, such as using an oxygen sensor to detect oxygen concentration, or multiple parameters including carbon dioxide concentration.

[0113] It is understood that the air conditioner in this embodiment automatically detects the indoor air quality when it is turned on, and determines whether to turn on the fresh air mode based on the detection results. In this way, the function of the air conditioner can be made more intelligent.

[0114] Step S102: If the indoor air quality meets the first preset condition, the rapid fresh air mode is activated, and a fresh air mode activation signal is generated.

[0115] In this embodiment, the first preset condition is configured such that the carbon dioxide concentration is greater than a first preset value. Generally speaking, when the carbon dioxide concentration in a person's environment rises to 1000 PPM (i.e., 1%), the person will experience symptoms such as lethargy, difficulty concentrating, and palpitations. Therefore, the first preset value can be configured to 1000 PPM. Of course, in some embodiments, the first preset value can also be configured to other values, such as 900 PPM or 1100 PPM; this application does not specifically limit this. In other embodiments, the first preset condition can also be a range value, such as 900 PPM to 1100 PPM.

[0116] In rapid fresh air mode, the control hood moves to the second position, and both the first and second baffles open to their maximum extent. This simultaneously opens the fresh air inlet, the secondary air inlet, and the air inlet of the second air duct. Both the first and second impellers operate, thereby maximizing indoor air circulation while supplementing with fresh outdoor air, achieving rapid ventilation. The heat exchanger does not operate during this mode. This rapid fresh air mode is suitable for situations where the indoor space has not been ventilated for a long time and it is inconvenient to open windows, or when the air conditioner has just been turned on.

[0117] Step S103: If the indoor air quality meets the second preset condition, the comfortable fresh air mode is turned on, and a fresh air mode turn-on signal is generated.

[0118] In this embodiment, the second preset condition is configured such that the carbon dioxide concentration is less than or equal to the first preset value and greater than the second preset value, wherein the second preset value is less than the first preset value. Specifically, the first preset value is configured as 1000 PPM, and the second preset value is configured as 450 PPM. That is, when the carbon dioxide concentration is less than or equal to 1000 PPM and greater than 450 PPM, the comfortable fresh air mode is activated. Of course, in other embodiments, the second preset value can also be configured as other values, such as 500 PPM, and this application does not specifically limit it in this regard.

[0119] In Comfort Fresh Air mode, the control hood moves to the second position, and the second baffle opens, activating the heat exchanger, the first fan wheel, and the second fan wheel. At this time, the user can freely set the heat exchange mode and preset temperature, for example, setting a cooling mode with a preset temperature of 18℃. It can be understood that Comfort Fresh Air mode is a second heat exchange mode, distinct from the first heat exchange mode, where the heat exchange efficiency is higher. In this way, the air conditioner can continuously cool or heat the indoor air while simultaneously introducing fresh air to replenish the indoor space and reduce fluctuations in indoor temperature.

[0120] Optionally, in the Comfort Fresh Air mode, the first baffle can also be opened, for example, to a 50% opening, to accelerate the circulation of indoor air. Further optionally, in the Comfort Fresh Air mode, if the user also activates the No-Wind Mode, the second louver is controlled to swing upward so that the airflow from the first air outlet is tilted upward, thereby preventing the airflow from the first air outlet from blowing directly on the human body and achieving a No-Wind effect.

[0121] It is understandable that when an air conditioner runs in the first heat exchange mode or the internal circulation mode for a long time in a relatively enclosed indoor space, the indoor air quality will deteriorate. If the carbon dioxide concentration is detected to exceed the second preset value in real time, the air conditioner will automatically switch from the first heat exchange mode to the comfortable fresh air mode so that the indoor air quality can be stabilized at a better state.

[0122] In this embodiment, the indoor air quality is determined based on the measured carbon dioxide concentration in the indoor space. For cases of poor indoor air quality (i.e., carbon dioxide concentration greater than 1000 PPM), the system automatically switches to a rapid fresh air mode to quickly replace the indoor air, thereby improving the user experience. Secondly, when the air conditioner causes poor indoor air quality after running for a period of time, it can automatically switch from the first heat exchange mode or internal circulation mode to a comfortable fresh air mode to stabilize the indoor air quality at a relatively optimal level.

[0123] Please refer to Figure 16 In the third embodiment of the air conditioner control method of the present invention, based on the aforementioned second embodiment, after the step of detecting the indoor air quality of the indoor space, the air conditioner control method further includes steps S104 to S106, as follows:

[0124] Step S104: If the carbon dioxide concentration in the indoor space is less than the second preset value, determine whether an internal circulation mode is preset.

[0125] Step S105: If so, activate the internal circulation mode and control the air guide to be in the second position.

[0126] Specifically, in the internal circulation mode, the control fan hood is moved to the second position and the second fan wheel is working. The control second baffle is closed and the first baffle is opened to prevent fresh air from entering the second air duct, and the indoor air is circulated by the auxiliary air inlet, the fan hood, the second air duct and the second fan wheel. At this time, the heat exchanger and the first fan wheel can work or not work.

[0127] Optionally, if the user also presets a windless mode, that is, if the user simultaneously activates both the internal circulation mode and the windless mode, then the control hood moves to the second position, the first fan wheel is deactivated while the second fan wheel is activated, the second baffle is closed while the first baffle is opened, the first louver is completely closed, and the heat exchanger is deactivated. In this case, only indoor air flowing in from the secondary air inlet is guided into the second air duct, with most of it flowing to the second air outlet and a small portion flowing to the first air outlet. It can be understood that when the windless mode is deactivated and the internal circulation mode is retained, both the heat exchanger and the first fan wheel are activated to achieve indoor air heat exchange, thereby maintaining a stable indoor temperature.

[0128] Step S106: If not, start the first heat exchange mode.

[0129] Specifically, in the first heat exchange mode, the heat exchanger is controlled to work, the air guide is controlled to be in the first position, and both the first and second impellers are controlled to work. In this way, the air flowing through the heat exchanger is supplied to the outside through the first and second air ducts respectively. That is, both the first and second air outlets supply air to the outside, which helps to improve the heat exchange efficiency of the air conditioner.

[0130] In this embodiment, for situations where the indoor air quality is relatively good (i.e., the carbon dioxide concentration is less than 450 PPM), since there is no need to introduce fresh air, the air conditioner can be turned on in internal circulation mode or the first heat exchange mode. In this way, the power consumed by the air conditioner when introducing fresh air and maintaining a stable indoor temperature can be saved.

[0131] The present invention also proposes a computer-readable storage medium storing an air conditioner control program, which, when executed by a processor, can perform the steps of the aforementioned air conditioner control method.

[0132] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
