[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0040] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0041] To address the technical problem of low air supply efficiency in the prior art, this application provides an air supply component and air conditioning equipment, an air supply control method and device. By setting a variable-position volute, which is located in different positions under different air supply conditions, it is beneficial to provide different guiding effects for different wind directions, thereby comprehensively improving the air supply efficiency under various wind direction conditions in reversible wind directions.

[0042] This embodiment provides an air supply component, which may include: a lower air guide assembly 1, a cross-flow fan blade 2 and a volute 3 disposed within a housing 4, and a housing 4; the lower air guide assembly 1 is located below the cross-flow fan blade 2;

[0043] like Figure 1 As shown, in the first state of upward airflow, the volute 3 is located above the cross-flow fan blade 2, and the volute 3 is connected to the casing 4 on one side.

[0044] like Figure 2 As shown, in the second state of downward airflow, the volute 3 is located on one side of the cross-flow fan blade 2, and the volute 3 and the lower air guide assembly 1 are connected to form a profile.

[0045] In this embodiment, the air supply component can be applied to air conditioning equipment, fans, or other types of equipment with air supply functions. The cross-flow fan blades 2 and volute 3 disposed within the housing 4 can refer to the housing 4 surrounding the cross-flow fan blades 2 and volute 3. The lower air guide assembly 1 can be located at the lower end of the air supply component, for example, at the lower air outlet of the air supply component. Exemplarily, the lower air guide assembly 1 may include at least one lower air guide plate.

[0046] In one embodiment, the cross-flow fan blade 2 can be located in the middle of the air supply component, for example, between the upper and lower air outlets of the air supply component; the cross-flow fan blade 2 can be used to increase the air pressure and air volume of the air supply.

[0047] In one embodiment, the cross-flow fan blade 2 rotates in the same direction in the first and second states, for example, both in a counterclockwise direction.

[0048] In one embodiment, the lower air guide assembly 1 is located at the lower air outlet of the air supply component, or serves as the lower air outlet of the air supply component. In a first state, the lower air outlet is used for air intake, and in a second state, the lower air outlet is used for air exhaust.

[0049] In one embodiment, the volute 3 can be a strip-shaped structure, for example, the volute 3 can have a curvature that can adapt to the edge of the cross-flow fan 2. In the first state of upward airflow, the volute 3 can cover at least a portion of the cross-flow fan 2.

[0050] In one embodiment, in the first state of upward airflow, the lower air guide component 1 is in the open state, and the airflow enters the lower air guide component 1 and the cross-flow fan blade 2 sequentially from below; in the second state of downward airflow, the lower air guide component 1 is in the open state, and the airflow enters the cross-flow fan blade 2 and the lower air guide component 1 sequentially from above.

[0051] In one embodiment, in the third state where operation is stopped, the volute 3 can be positioned above the cross-flow fan blade 2, that is, the same position as the volute 3 in the first state. In the third state, the lower air guide assembly 1 can be in the closed state.

[0052] In one embodiment, in the second state, the volute 3 is located on one side of the cross-flow fan 2, for example, the right side. The other side of the cross-flow fan 2, for example, the left side, may include the housing 4 of the air supply component, and may also include a baffle 5, etc.

[0053] In one embodiment, the volute 3 and the lower air guide assembly 1 are connected to form a profile, which can refer to the volute 3 and the lower air guide assembly 1 forming a volute 3 profile for airflow. This volute 3 profile and the edge of the cross-flow fan blade 2 can form an air duct for airflow.

[0054] In one embodiment, in the first state, the volute 3 is located above the cross-flow fan blade 2, and one end of the volute 3 is connected to the housing 4 of the air supply component, for example, the second end of the volute 3 is connected to the housing 4, thereby preventing airflow from entering the cross-flow fan blade 2 from above and causing a reduction in air supply efficiency. Here, the housing 4 on one side can refer to the housing 4 on one side of the cross-flow fan blade 2, such as the housing 4 on the right or left side, and the connection can refer to a method such as engagement by a stop.

[0055] In one embodiment, in the second state, the first end of the volute 3 can be connected to the housing 4, and the second end of the volute 3 can be connected to the lower air guide assembly 1 to form a profile. In this way, through the cooperation of the housing 4 and the volute 3, the position of the volute 3 can be fixed in different states, and different profiles can be formed to prevent reverse airflow from entering the cross-flow fan blade 2 or to guide airflow into the air duct, thereby improving air delivery efficiency.

[0056] In one embodiment, the air supply component may further include an upper air guide assembly 8, which is located above the cross-flow fan blade 2 and the volute 3, i.e., at the upper end of the air supply component, such as at the upper air outlet of the air supply component or serving as the upper air outlet of the air supply component. In a first state, the upper air outlet is used for air outlet, and in a second state, the upper air outlet is used for air inlet.

[0057] In one embodiment, a heat exchanger may be further included between the upper air guide assembly 8 and the volute 3, which can be used for heat exchange and temperature control during air supply. In the first state, the volute 3 is located above the cross-flow fan blade 2, which can effectively prevent the airflow entering below the heat exchanger from flowing downwards into the air outlet.

[0058] In one embodiment, the air supply component may further include at least one volute tongue around the cross-flow fan blade 2 for guiding the airflow direction together with the volute 3 and the housing 4.

[0059] In one embodiment, the lower air guide assembly 1 can perform a swing function by oscillating in either a first or second state. For example, at least one lower air guide plate included in the lower air guide assembly 1 can oscillate by changing its opening angle.

[0060] Thus, through the design of the variable-position volute 3, when air is supplied upwards, it can facilitate the airflow to the cross-flow fan blade 2 to increase the air supply pressure and air volume. When air is supplied downwards, it can be moved to connect with the side and the lower air guide component 1 to form the volute 3 profile, which facilitates the airflow to flow smoothly from the side to the bottom. Moreover, it avoids the volute 3 guiding the reverse airflow in its original position, which would cause the downward air supply resistance to increase. Therefore, it can comprehensively improve the air supply effect in different reverse downward air supply states.

[0061] In some embodiments, such as Figure 3 As shown, the lower air guide assembly 1 includes at least: a first lower air guide plate 11 and a second lower air guide plate 12;

[0062] In the first state, the second lower air guide plate 12 is located in the first position;

[0063] In the second state, the second lower air guide plate 12 is located at the second position where it is connected to the volute 3.

[0064] In one embodiment, the position of the first lower air guide plate 11 in the first state and the second state can remain fixed, or the opening angle of the first lower air guide plate 11 in the second state is smaller than the opening angle in the first state.

[0065] In one embodiment, the first position can be a position parallel to the first lower air guide plate 11, and the second position can be moved upward relative to the first position to be closer to the cross-flow fan blade 2 so as to dock with the volute 3.

[0066] In one embodiment, the gap between the profile formed by the second lower air guide plate 12 and the volute 3 and the cross-flow fan blade 2 gradually widens from top to bottom. This gap is the air duct, which facilitates the airflow to pass through the gap from top to bottom and be delivered downwards.

[0067] In one embodiment, the opening angle of the second lower air guide plate 12 in the second position may be smaller than the opening angle in the first position. The opening angle can refer to the opening angle relative to the closed state, such as the angle between the air guide plate and the horizontal direction.

[0068] In one embodiment, when the second position is close to the cross-flow fan blade 2 and the second lower air guide plate 12 is in the second position, one end is connected to the volute 3, and the other end is located below, for example, close to the downwind outlet.

[0069] In this way, by setting the lower air guide plate to a positional design, when the air is directed downwards, the lower air guide plate moves upwards to connect with the volute 3 to form a profile. This eliminates the need to design the volute 3 to be long enough to meet the connection requirements, and avoids the volute 3 being too large, which would affect the efficiency of upward air delivery. Thus, the air delivery effect can be optimized by using different positions under different conditions.

[0070] In some embodiments, the air supply component further includes: a baffle 5; the baffle 5 and the volute 3 in the second state are respectively located on different sides of the cross-flow fan blade 2;

[0071] like Figure 4 As shown, in the first state, the spoiler 5 is in a retracted state, and the air duct between the housing 4 on the side where the spoiler 5 is located and the cross-flow fan blade 2 is connected.

[0072] like Figure 5 As shown, in the second state, the spoiler 5 is in an extended state, which is used to block the airflow from flowing upward through the duct between the housing 4 and the cross-flow fan 2 on the side where the spoiler 5 is located.

[0073] In one embodiment, the housing 4 may surround the cross-flow fan blade 2 and the volute 3. The spoiler 5 may be disposed on the housing 4 on the side where the spoiler 5 is located, for example, the spoiler 5 may be movably disposed on the housing 4 on the side where the spoiler 5 is located.

[0074] In one embodiment, in the second state, the volute 3 is located to the right of the cross-flow fan blade 2, and the spoiler 5 is located to the left of the cross-flow fan blade 2. In the second state, the spoiler 5 is in an extended state, which can be interpreted as the spoiler 5 being horizontally positioned between the housing 4 and the cross-flow fan blade 2 on the side where the spoiler 5 is located.

[0075] In one embodiment, a groove is provided on the housing 4 on the side where the spoiler 5 is located. In the first state, the spoiler 5 is in a retracted state, which means that the spoiler 5 is retracted and placed in the groove. The spoiler 5 and the housing 4 on the side where the spoiler 5 is located are on the same plane, and the air duct between the housing 4 on the side where the spoiler 5 is located and the cross-flow fan blade 2 is connected.

[0076] In one embodiment, the gap between the housing 4 on the side where the spoiler 5 is located and the cross-flow fan 2 gradually widens from bottom to top, thereby facilitating the smooth upward discharge of airflow in the first state.

[0077] Thus, by setting up a variable-attitude spoiler 5, which works in conjunction with the volute 3, the air delivery effect can be optimized in different states of reversible downward wind. In the first state, the upward air delivery duct remains unobstructed, and in the second state, the resistance to the upward movement of the airflow is increased, thereby optimizing the air delivery efficiency.

[0078] In some embodiments, such as Figure 6 As shown, the air supply component further includes: a first volute tongue 6, and the lower end of the housing 4 on the side where the baffle 5 is located is connected to the first volute tongue 6;

[0079] In the second state, the first volute tongue 6 and the corresponding area of ​​the location of the spoiler 5 in the cross-flow fan blade 2 form an eccentric vortex.

[0080] In one embodiment, the first volute tongue 6 may be located below the cross-flow fan blade 2, for example, below the left side of the cross-flow fan blade 2. The first volute tongue 6 may be connected to the lower end of the housing 4 on the side where the spoiler 5 is located to form a profile.

[0081] In one embodiment, the first volute tongue 6 can serve as a volute throat structure in a first state, serving as the starting point of the upward airflow; and in a second state, it can serve as a volute tongue.

[0082] In one embodiment, in the second state, the airflow tends to flow upward from the left volute 3 under the drive of the cross-flow fan blade 2. The extended spoiler 5 is used to block the airflow from moving upward and to force the airflow into the cross-flow fan blade 2. An eccentric vortex is formed in the corresponding area of ​​the cross-flow fan blade 2 at the location of the first volute tongue 6 and the end of the spoiler 5, so that the internal airflow only tends to flow downward.

[0083] Thus, by cooperating with the first volute tongue 6 and the same-side spoiler 5, in the second state, the airflow can be blocked from moving upward and guided into the cross-flow fan blade 2 to form an eccentric vortex, thereby increasing the downward air pressure and air volume.

[0084] In some embodiments, such as Figure 7 As shown, the air supply component further includes: a second volute tongue 7, which is located above the cross-flow fan blade 2;

[0085] In the first state, the second volute tongue 7 is connected to the first end of the volute 3, and the second end of the volute 3 is connected to the housing 4 on the side where the volute 3 is located, in order to block the airflow from entering the cross-flow fan 2 from above.

[0086] In one embodiment, the second volute tongue 7 can be engaged, abutted, or otherwise connected to the first end of the volute shell 3. The position of the second volute tongue 7 can be the same in both the first and second states.

[0087] In one embodiment, the second volute tongue 7 can function as a deflector in the second state, guiding airflow from top to bottom into the interior of the cross-flow fan blade 2.

[0088] In one embodiment, in a first state, the second volute tongue 7 and the volute casing 3 cover at least a portion of the area above the cross-flow fan blade 2, which can prevent airflow from flowing back to the cross-flow fan blade 2 from above. For example, a heat exchanger is also included above the second volute tongue 7 and the volute casing 3, and a portion of the airflow discharged from bottom to top may return to the cross-flow fan blade 2 via the heat exchanger; the second volute tongue 7 and the volute casing 3 can prevent this portion of the airflow.

[0089] Thus, in the first state, the second volute tongue 7 can act as a volute tongue structure to dock with the volute shell 3. While fixing the position of the volute shell 3, it can also block the airflow from the top from entering the cross-flow fan blade 2 downwards, thereby improving the air delivery efficiency.

[0090] In some embodiments, in the first state, the gap between the volute 3 and the cross-flow fan blade 2 gradually narrows from the first end to the second end, and the second volute tongue 7 and the corresponding area of ​​the volute 3 in the cross-flow fan blade 2 form an eccentric vortex.

[0091] In one embodiment, the first end of the volute 3 is at the left end of the volute 3, and the second end is at the right end of the volute 3. The first end is farther away from the cross-flow fan 2 than the second end, that is, the first end is above the second end. The rotation direction of the cross-flow fan 2 can be counterclockwise.

[0092] In one embodiment, when the airflow passes through the second volute tongue 7, part of it flows outward and part enters the interior of the right volute 3. The gap between the right volute 3 and the cross-flow fan blade 2 gradually decreases, and the airflow is gradually forced into the cross-flow fan blade 2, forming an eccentric vortex. The eccentric vortex formed in the corresponding area of ​​the cross-flow fan blade 2 at the location of the second volute tongue 7 and the volute 3 can be interpreted as the eccentric vortex forming in the corresponding area of ​​the cross-flow fan blade 2 at the narrowest point of the gap between the second volute tongue 7 and the volute 3 and the cross-flow fan blade 2.

[0093] Thus, in the first state, the second volute tongue 7 and the volute shell 3 can guide part of the airflow to form an eccentric vortex in the cross-flow fan blade 2, thereby increasing the wind pressure and air volume of the upward air delivery.

[0094] In some embodiments, the first end of the volute 3 has a first stop portion 31, the second end of the volute 3 has a second stop portion 32, and the housing 4 on the side where the volute 3 is located has a third stop portion 41.

[0095] like Figure 8 As shown, in the first state, the second stop portion 32 is engaged with the third stop portion 41;

[0096] like Figure 9 As shown, in the second state, the first stop portion 31 is engaged with the third stop portion 41.

[0097] In one embodiment, in the first state, the volute 3 is connected to the housing 4 on one side, meaning that the volute 3 is engaged with the third stop 41 of the housing 4 through the second stop 32.

[0098] In one embodiment, the first stop 31 may be a structure that bends upward or extends upward, the second stop 32 may be a structure that bends upward or extends upward, and the third stop 41 may be a structure that bends downward or extends downward.

[0099] In one embodiment, the third stop 41 is located between the first stop 31 and the second stop 32, so that it can engage with the first stop 31 or the second stop 32 before and after the volute 3 changes position.

[0100] In one embodiment, the left and / or right sides of the third stop portion 41 may be provided with a slot or a snap-fit, and the right side of the first stop portion 31 and / or the left side of the second stop portion 32 may be provided with a snap-fit ​​or a slot for snapping with the third stop portion 41.

[0101] In this way, by setting a stop, the position of the volute 3 in the first and second states can be kept fixed, avoiding abnormal movement of the volute 3 that would lead to poor air delivery effect.

[0102] In some embodiments, such as Figure 10 As shown, the air supply component further includes: an upper air guide assembly 8, which is located above the cross-flow fan blade 2 and the volute 3;

[0103] In the first state, the opening angle of the upper air guide component 8 is smaller than the opening angle of the lower air guide component 1;

[0104] In the second state, the opening angle of the upper air guide component 8 is greater than the opening angle of the lower air guide component 1.

[0105] In one embodiment, the upper air guide assembly 8 may include at least one upper air guide plate. In a first state and a second state, the upper air guide assembly 8 may be in an open state, and in a third state, the upper air guide assembly 8 may be in a closed state.

[0106] In one embodiment, the upper air guide assembly 8 is located at the upper air outlet of the air supply component or serves as the upper air outlet of the air supply component. In a first state, the upper air outlet is used for air outlet, and in a second state, the upper air outlet is used for air inlet.

[0107] In one embodiment, in the first state, the opening angle of the upper air guide component 8 is smaller than the opening angle of the lower air guide component 1. For example, the opening angle of the upper air guide component 8 can be in the range of 10° to 75°, and the opening angle of the lower air guide component 1 can be 90°.

[0108] In one embodiment, in the second state, the opening angle of the upper air guide component 8 is greater than the opening angle of the lower air guide component 1. For example, the opening angle of the upper air guide component 8 can be 90°, and the opening angle of the lower air guide component 1 can be in the range of 10° to 75°.

[0109] Thus, when air is supplied upwards, the upper air guide component 8 opens at a smaller angle, and the resistance at the upper air outlet is greater than that at the lower air outlet. When air is supplied downwards, the upper air guide component 8 opens at a larger angle, and the resistance at the upper air outlet is less than that at the lower air outlet, thereby improving the air supply efficiency under different wind direction conditions.

[0110] This application also provides an air conditioning device, including the air supply component described in any one or more of the foregoing embodiments.

[0111] This application also provides an air supply control method, applied to the air supply components described in any one or more of the foregoing embodiments, such as... Figure 11 As shown, the method includes:

[0115] In this embodiment, the specific implementation methods and related embodiments can be referred to the content described in the aforementioned air supply component section, and will not be repeated here.

[0116] In one embodiment, the method may further include: in response to a first state where the air supply state is upward air supply, controlling the second lower air guide plate 12 to be located in a first position; in response to a second state where the air supply state is downward air supply, controlling the second lower air guide plate 12 to be located in a second position where it is connected to the volute 3, and the second position being closer to the cross-flow fan blade 2 than the first position.

[0117] In one embodiment, the method may further include: in response to a first state where the air supply state is upward air supply, controlling the spoiler 5 to be in a retracted state, and the air duct between the housing 4 and the cross-flow fan 2 on the side where the spoiler 5 is located is connected; in response to a second state where the air supply state is downward air supply, controlling the spoiler 5 to be in an extended state, for blocking the airflow from flowing upward in the air duct between the housing 4 and the cross-flow fan 2 on the side where the spoiler 5 is located.

[0118] In one embodiment, the method may further include: in response to a first state where the air supply state is upward air supply, controlling the second volute tongue 7 to engage with the first end of the volute 3, the second end of the volute 3 being engaged with the housing 4 on the side where the volute 3 is located, for blocking airflow from entering the cross-flow fan 2 from above.

[0119] In one embodiment, the method may further include: controlling the second stop 32 to engage with the third stop 41 in response to a first state in which the air supply state is upward air supply; and controlling the first stop 31 to engage with the third stop 41 in response to a second state in which the air supply state is downward air supply.

[0120] In one embodiment, the method may further include: in response to a first state where the air supply state is upward air supply, controlling the opening angle of the upper air guide component 8 to be smaller than the opening angle of the lower air guide component 1; and in response to a second state where the air supply state is downward air supply, controlling the opening angle of the upper air guide component 8 to be greater than the opening angle of the lower air guide component 1.

[0121] In one embodiment, step S10 may include: if the current operating mode is cooling mode, determining the required air supply state as a first state of upward air supply; if the current operating mode is heating mode, determining the required air supply state as a second state of downward air supply.

[0122] In one embodiment, step S10 may further include: if the current working mode is standby or power-off mode, determining it to be the third state.

[0123] In this way, upward airflow is used when cooling and downward airflow is used when heating. Different airflow states can be selected based on the different densities of hot and cold air, and better airflow effect can be provided by combining different positions of the volute 3.

[0124] As one possible implementation method, such as Figure 12 and Figure 13 As shown, the air outlets are in the upper and lower air outlet states, respectively. The upper air outlet has four upper air guide plates as upper air guide components 8, which are used to guide the air when the upper air outlet is closed or when the air outlet is in the upper air outlet.

[0125] The heat exchanger is located below the upper air outlet for air heat exchange, and below it is the cross-flow fan system, namely the cross-flow fan blades 2.

[0126] 3 is the rotating volute; when the air is discharged from the top, the rotating volute is located at... Figure 12 At the indicated location, on one hand, the rotating volute acts as an extension of the second volute tongue, guiding the airflow behind the volute tongue into the impeller interior. Here, the gap between the volute tongues needs to gradually decrease. On the other hand, a seal is formed between the rotating volute and the front casing to prevent airflow from flowing back from the top of the evaporator to the lower air outlet. During downward airflow, the rotating volute rotates downwards to become the starting section of the downward airflow volute.

[0127] The cross-flow fan blades 2 rotate counterclockwise in both the top and bottom air outlet modes.

[0128] The second lower air guide plate 12 at the lower air outlet has three fixed postures. The first posture is the lower air outlet posture, which combines with the rotating volute to form the lower air outlet volute, thereby extending the length of the lower air outlet volute. The second posture is the upper air outlet posture, which rotates outward at the air outlet to enlarge the lower air outlet during the upper air outlet process. The third posture is the air outlet closed posture, which, together with the first lower air guide plate 11 at the lower air outlet, is used to close the air outlet after the air conditioner is turned off.

[0129] The first lower air guide plate 11 at the downwind outlet can guide the air out of the downwind outlet vertically downward to the ground, and at the same time, it can also realize the up and down air sweeping function during rotation.

[0130] The first volute tongue 6, during the upward airflow process, serves as the volute throat structure and the starting point of the upward airflow; during the downward airflow process, it serves as the volute tongue.

[0131] The spoiler 5 extends during downward airflow to increase airflow resistance within the left-side duct, thereby forcing the airflow to exit towards the right side of the volute and creating an eccentric vortex in the area between the first volute tongue on the left and the spoiler. During upward airflow, it retracts, forming the profile of the upward airflow volute section.

[0132] The second volute 7 is a volute structure during the upward airflow process and a guide vane during the downward airflow process, guiding the airflow into the interior of the cross-flow fan blades. Its position is fixed.

[0133] In the first state of upward air supply, the rotating volute and guide vanes rotate, while the spoiler is closed. Airflow enters through the lower inlet and passes through the cross-flow fan. Because the spoiler is closed, the left volute is smooth, and the gap between it and the impeller (cross-flow fan) gradually widens from bottom to top, allowing for smooth airflow discharge. When the airflow passes the second volute tongue, part flows outwards and part enters the right volute. The gap between the right volute and the impeller gradually decreases from top to bottom, gradually forcing the airflow into the impeller and forming an eccentric vortex. This eccentric vortex is located between the second volute tongue and the minimum position between the rotating volute and the impeller. The rotating volute effectively prevents the airflow below the heat exchanger from flowing downwards to the lower inlet. At this point, the lower inlet is the air inlet, and the upper inlet is the air outlet.

[0134] In the second state (downward air outlet), the rotating volute and guide vanes rotate, and the second lower guide vane rotates until it contacts the rotating volute, forming the volute profile. The spoiler opens. Airflow enters from the upper inlet, passes through the cross-flow fan blades, and flows to the lower inlet. At this time, the fluid at the lower inlet tends to flow upward from the left side of the volute under the influence of the cross-flow fan blades. The open spoiler blocks the upward movement of the airflow and forces the fluid into the impeller, forming an eccentric vortex in the area between the first volute tongue and the end of the spoiler, causing the internal airflow to only tend to flow downward. In this state, the lower inlet is the air outlet, and the upper inlet is the air inlet.

[0135] The air guide plate operates as follows: During the upward and downward airflow processes, the air guide plate has a significant impact on the resistance and airflow at the air inlet and outlet.

[0136] During the upward airflow process, to ensure that the resistance at the upward air outlet is greater than that at the downward air outlet by a certain value, thus stabilizing the airflow, the downward air outlet guide vane needs to be opened to... Figure 12 The position shown is designed to maximize the lower air inlet and minimize resistance; while the upper air inlet deflector serves to guide the airflow.

[0137] During the downward airflow process, the resistance at the downward air outlet should be greater than that at the upward air outlet by a certain value to ensure stable airflow. The upward air outlet guide vane should be opened to its maximum to minimize the upward air outlet resistance. The second guide vane at the downward air outlet is connected to the rotating volute to form a complete and continuous volute. The first guide vane at the downward air outlet can be used for vertical airflow sweeping.

[0138] Under normal conditions, the air conditioner's default cooling mode is bottom air intake and top air outlet, which ensures that cold air gradually descends from the top to the bottom of the room. The bottom air intake draws in air from the bottom, creating airflow circulation in the room and preventing cold air from accumulating at the bottom.

[0139] In heating mode, the default mode is anti-direct-blow mode, where hot air is blown vertically downwards from the air outlet, and the upper air inlet absorbs air from the top of the room, so that the airflow in the room forms a whole-house circulation, preventing hot air from accumulating at the top.

[0140] When the machine is off, the air guide plate is closed and the rotating plate is fully retracted into its original position.
