[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0040] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] In order to solve the technical problem of low air supply efficiency in the prior art, the present application provides an air supply component and air-conditioning equipment, an air supply control method and a device. By setting a variable-position volute, it is in different positions under different air supply states, thereby providing different guiding effects for different wind directions, and comprehensively improving the air supply efficiency under each wind direction state in the reversible wind direction.

[0042] The present embodiment provides an air supply component, which may include: a lower air guide assembly 1, a crossflow fan blade 2 and a volute 3 arranged in a housing 4, and the housing 4; the lower air guide assembly 1 is located below the crossflow fan blade 2;

[0043] like Figure 1 As shown, in the first state of upward air supply, the volute 3 is located above the crossflow fan blade 2, and the volute 3 is connected to the housing 4 on one side;

[0044] like Figure 2 As shown, in the second state of downward air supply, the volute 3 is located on one side of the crossflow fan blade 2, and the volute 3 is connected to the lower air guide assembly 1 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 function. The crossflow blades 2 and the volute 3 arranged in the housing 4 can refer to the housing 4 surrounding the crossflow blades 2 and the 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 can include at least one lower air guide plate.

[0046] In one embodiment, the crossflow blades 2 may be located in the middle of the air supply component, for example, between the upper air outlet and the lower air outlet of the air supply component; the crossflow blades 2 may be used to increase the air pressure and air volume of the air supply.

[0047] In one embodiment, the rotation directions of the crossflow blade 2 in the first state and the second state are consistent, for example, both are counterclockwise.

[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 discharge.

[0049] In one embodiment, the volute 3 may be a strip-shaped structure, for example, the volute 3 may have a curvature, which may be adapted to the edge of the crossflow blade 2. In the first state of upward air supply, the volute 3 may cover at least a portion of the crossflow blade 2.

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

[0051] In one embodiment, in the third state of stopping working, the volute 3 may be located above the crossflow blades 2, that is, the position of the volute 3 is consistent with that in the first state. In the third state, the lower air guide assembly 1 may be in a closed state.

[0052] In one embodiment, in the second state, the volute 3 is located on one side, such as the right side, of the crossflow blade 2. The other side, such as the left side, of the crossflow blade 2 may include a housing 4 of an air supply component and may also include a spoiler 5 and the like.

[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 being connected to form a volute 3 profile for airflow. The volute 3 profile and the edge of the crossflow 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 crossflow 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, etc., so that the airflow can be prevented from entering the crossflow blade 2 from the top downward, resulting in a decrease in air supply efficiency. Here, the housing 4 on one side can refer to the housing 4 on one side of the crossflow blade 2, such as the housing 4 on the right or left side, etc., and the connection can refer to a method such as clamping through a stopper.

[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 is connected to the lower air guide assembly 1 to form a profile. In this way, through the cooperation between the housing 4 and the volute 3, the position of the volute 3 is fixed in different states, and different profiles are formed to prevent the reverse airflow from entering the crossflow fan blade 2 or guide the airflow into the air duct, thereby improving the air supply efficiency.

[0056] In one embodiment, the air supply component may further include an upper air guide assembly 8, which is located above the crossflow blades 2 and the volute 3, that is, located at the upper end of the air supply component, for example, located at the upper air outlet of the air supply component or serving as the upper air outlet of the air supply component. In the first state, the upper air outlet is used for air outlet, and in the second state, the upper air outlet is used for air intake.

[0057] In one embodiment, a heat exchanger may be further included between the upper air guide assembly 8 and the volute 3, and the heat exchanger may be used for heat exchange and temperature control during air supply. In the first state, the volute 3 is located above the crossflow blades 2, which can effectively prevent the airflow entering below the heat exchanger from flowing to the lower 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 , which is used to guide the air flow direction together with the volute 3 and the housing 4 .

[0059] In one embodiment, the lower air guide assembly 1 can realize the wind sweeping function by swinging in the first state or the second state. For example, at least one lower air guide plate included in the lower air guide assembly 1 can swing by changing the opening angle.

[0060] In this way, through the design of the variable position volute 3, when supplying air upward, the airflow can be guided to the crossflow fan blades 2 to increase the air pressure and air volume. When supplying air downward, it can be moved to connect with the side and the lower air guide component 1 to form the volute 3 profile, which is beneficial for the airflow to flow smoothly from the side to the bottom, and avoids the volute 3 guiding the reverse airflow in the original position, resulting in an increase in the downward air supply resistance, thereby comprehensively improving the air supply effect of different air supply states in the reversible wind downward direction.

[0061] In some embodiments, Figure 3 As shown, the lower air guide assembly 1 at least includes: 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 at a first position;

[0063] In the second state, the second lower air guide plate 12 is located at a second position docking with 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 may 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 may be a position parallel to the first lower air guide plate 11 , and the second position may be moved upwards compared to the first position to be closer to the crossflow 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 crossflow fan blade 2 gradually widens from top to bottom. The gap is an air duct, which facilitates the airflow to pass through the gap from top to bottom.

[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 may refer to the opening angle compared to the closed state, such as the angle between the air guide plate and the horizontal direction.

[0068] In one embodiment, the second position is close to the crossflow blade 2 and when 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 lower air outlet.

[0069] In this way, by setting the lower air guide plate to a variable position design, when supplying air downward, the lower air guide plate moves upward to connect with the volute 3 to form a profile line. There is no need to design the volute 3 to be longer to meet the docking requirements, thereby avoiding the volute 3 being too large in size and affecting the efficiency of upward air supply, so that the air supply effect can be optimized through different positions in different states.

[0070] In some embodiments, the air supply component further includes: a spoiler 5; the spoiler 5 and the volute 3 in the second state are respectively located on different sides of the crossflow 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 shell 4 on the side where the spoiler 5 is located and the crossflow blade 2 is connected;

[0072] like Figure 5 As shown, in the second state, the spoiler 5 is in an extended state, so as to block the airflow from flowing upward in the air duct between the shell 4 and the cross-flow blades 2 on the side where the spoiler 5 is located.

[0073] In one embodiment, the housing 4 may surround the crossflow blades 2 and the volute 3. The spoiler 5 may be disposed on the housing 4 at the side where the spoiler 5 is located, for example, the spoiler 5 may be movably disposed on the housing 4 at the side where the spoiler 5 is located.

[0074] In one embodiment, in the second state, the volute 3 is located on the right side of the crossflow blade 2, and the spoiler 5 is located on the left side of the crossflow blade 2. In the second state, the spoiler 5 is in an extended state, which may mean that the spoiler 5 is horizontally placed between the housing 4 and the crossflow blade 2 on the side where the spoiler 5 is located.

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

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

[0077] In this way, by setting a spoiler 5 with variable posture, the air supply effect in different states of reversible wind direction can be optimized in cooperation with the volute 3. In the first state, the air duct for upward air supply is kept unobstructed, and in the second state, the resistance of the upward air flow is increased to optimize the air supply efficiency.

[0078] In some embodiments, 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 spoiler 5 is located is connected to the first volute tongue 6;

[0079] In the second state, an eccentric vortex is formed in a corresponding area of ​​the crossflow blade 2 where the first volute tongue 6 and the spoiler 5 are located.

[0080] In one embodiment, the first volute tongue 6 may be located below the crossflow blade 2, for example, below the left side of the crossflow blade 2, and the first volute tongue 6 may be connected to the lower end of the shell 4 on the side where the spoiler 5 is located to form a profile line.

[0081] In one embodiment, the first volute tongue 6 can be used as a volute throat structure and as the starting end of the upward airflow in the first state; and can be used as a volute tongue in the second state.

[0082] In one embodiment, in the second state, the airflow has a tendency to flow upward from the left volute 3 driven by the crossflow blade 2, and the spoiler 5 in the extended state is used to block the airflow from moving upward and press the airflow into the crossflow blade 2, and form an eccentric vortex in the corresponding area of ​​the crossflow blade 2 at the position of the first volute tongue 6 and the end of the spoiler 5, so that the internal airflow has only a tendency to flow downward.

[0083] In this way, through the cooperation between the first volute tongue 6 and the spoiler 5 on the same side, in the second state, the airflow can be blocked from moving upward and guided into the crossflow fan blade 2 to form an eccentric vortex, thereby increasing the wind pressure and air volume of the downward air supply.

[0084] In some embodiments, Figure 7 As shown, the air supply component further includes: a second volute tongue 7, and the second volute tongue 7 is located above the crossflow 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 shell 4 on the side of the volute 3, which is used to block the airflow from entering the crossflow blade 2 from above the crossflow blade 2.

[0086] In one embodiment, the second volute tongue 7 may be engaged, abutted or otherwise connected to the first end of the volute 3. The position of the second volute tongue 7 may be consistent in the first state and the second state.

[0087] In one embodiment, the second volute tongue 7 can serve as a guide plate in the second state to guide the airflow into the inside of the cross-flow blade 2 from top to bottom.

[0088] In one embodiment, in the first state, the second volute 7 and the volute 3 cover at least part of the area above the crossflow blade 2, and can block the airflow from above to flow back to the crossflow blade 2. Exemplarily, a heat exchanger is also included above the second volute 7 and the volute 3, and part of the airflow discharged from bottom to top may be returned to the crossflow blade 2 by the heat exchanger, and the second volute 7 and the volute 3 can block this part of the airflow.

[0089] In this way, the second volute tongue 7 can be connected to the volute 3 as a volute tongue structure in the first state. On the basis of fixing the position of the volute 3, it can also block the upper airflow from entering the cross-flow fan blade 2 downward, thereby improving the air supply efficiency.

[0090] In some embodiments, in the first state, the gap between the volute 3 and the crossflow 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 crossflow 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 crossflow blade 2 than the second end, that is, the first end is above the second end. The crossflow blade 2 can rotate counterclockwise.

[0092] In one embodiment, when the airflow passes through the second volute tongue 7, part of it flows outward and part of it flows into the right volute 3, the gap between the right volute 3 and the crossflow fan blade 2 gradually decreases, and the airflow is gradually pressed into the crossflow fan blade 2 to form an eccentric vortex. The eccentric vortex is formed in the corresponding area of ​​the crossflow fan blade 2 where the second volute tongue 7 and the volute 3 are located, which can refer to the eccentric vortex formed in the corresponding area of ​​the crossflow fan blade 2 where the gap between the second volute tongue 7 and the volute 3 and the crossflow fan blade 2 is the narrowest.

[0093] In this way, the second volute tongue 7 and the volute 3 can guide part of the airflow to form an eccentric vortex in the crossflow fan blade 2 in the first state, thereby increasing the wind pressure and air volume of the upward air supply.

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

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

[0096] like Fig. 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, which means that the volute 3 is clamped with the third stopper 41 of the housing 4 through the second stopper 32 .

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

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

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

[0101] In this way, the stopper can be provided to keep the position of the volute 3 fixed in the first state and the second state, thereby preventing the volute 3 from moving abnormally and causing poor air supply effect.

[0102] In some embodiments, Fig.10 As shown, the air supply component further includes: an upper air guide assembly 8, the upper air guide assembly 8 is located above the crossflow fan blade 2 and the volute 3;

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

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

[0105] In one embodiment, the upper air guide assembly 8 may include at least one upper air guide plate. In the first state and the second state, the upper air guide assembly 8 may be in an open state. In the 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 the first state, the upper air outlet is used for air outlet, and in the second state, the upper air outlet is used for air intake.

[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 may range from 10° to 75°, and the opening angle of the lower air guide component 1 may 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 range from 10° to 75°, etc.

[0109] In this way, when supplying air upward, the upper air guide component 8 opens at a smaller angle, and the upper air outlet resistance is greater than the lower air outlet resistance. When supplying air downward, the upper air guide component 8 opens at a larger angle, and the upper air outlet resistance is less than the lower air outlet resistance, thereby facilitating the air supply efficiency under different wind direction conditions.

[0110] The present application also provides an air conditioning device, comprising the air supply component described in any one or more of the aforementioned embodiments.

[0111] The present application also provides an air supply control method, which is applied to the air supply component described in any one or more of the above embodiments, such as Fig.11 As shown, the method includes:

[0112] S10: Determine the required air supply state based on the current working mode;

[0113] S20: In response to the air supply state being the first state of upward air supply, the volute 3 is controlled to be located above the crossflow fan blade 2 and connected to the housing 4 on one side;

[0114] S30: In response to the air supply state being the second state of downward air supply, the volute 3 is controlled to be located at one side of the crossflow fan blade 2 and to be connected with the lower air guide assembly 1 to form a profile.

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

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

[0117] In one embodiment, the method may further include: in response to the air supply state being a first state of upward air supply, controlling the spoiler 5 to be in a retracted state, and connecting the air duct between the shell 4 on the side where the spoiler 5 is located and the cross-flow fan blade 2; in response to the air supply state being a second state of 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 shell 4 on the side where the spoiler 5 is located and the cross-flow fan blade 2.

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

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

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

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

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

[0123] In this way, upward air supply is used during cooling, and downward air supply is used during heating. Different air supply states can be selected in combination with the different densities of cold and hot air, and then better air supply effects can be provided in combination with different positions of the volute 3.

[0124] As a possible implementation, Fig.12 and Fig.13 As shown, they are upper air outlet 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 air when closing the upper air outlet or when the upper air outlet is in progress.

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

[0126] The volute 3 is a rotating volute. When the air is discharged upward, the rotating volute is located at Fig.12 In the position shown, on the one hand, the rotating volute is used as an extension of the second volute tongue to guide the airflow behind the volute tongue to the inside of the impeller. Here, the volute tongue gap needs to be gradually reduced. On the other hand, the rotating volute and the front housing are sealed to prevent the airflow from flowing back from the top of the evaporator to the lower air outlet. When the air is discharged from the lower side, the rotating volute rotates to the lower side as the starting section of the lower air discharge volute.

[0127] The up / down air outlet modes of the crossflow fan blade 2 are both counterclockwise rotation.

[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. It is combined with the rotating volute to form a lower air outlet volute to achieve the purpose of extending the length of the lower air outlet volute. The second posture is the upper air outlet posture. It is rotated outward to the outer end of the air outlet to increase the lower air outlet during the upper air outlet process. The third posture is the air outlet closing posture, which is used together with the first lower air guide plate 11 at the lower air outlet to close the air outlet after the air conditioner is turned off.

[0129] The first lower wind guide plate 11 of the lower wind outlet can guide the wind guided out of the lower wind outlet vertically downward to the ground, and can also realize the upward and downward wind sweeping function during the rotation process.

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

[0131] The spoiler 5 is extended during the downward air flow process to increase the resistance of the air flow in the left air duct, thereby forcing the air flow to flow out to the right volute, thereby forming an eccentric vortex in the area between the left first volute tongue and the spoiler. During the upward air flow process, it is retracted to form the profile of the upward air flow volute section.

[0132] The second volute tongue 7 is a volute tongue structure during the upward air discharge process, and is a guide plate during the downward air discharge process, guiding the airflow into the interior of the cross-flow fan blade, and its position is fixed.

[0133] In the upper air supply, i.e. the first state, the rotating volute and the wind guide plate rotate, and the spoiler is closed. The airflow enters from the lower air port and passes through the crossflow blades. At this time, since the spoiler is closed, the left volute is smooth and the gap with the impeller, i.e. the crossflow blade, gradually expands from bottom to top, so that the airflow can be discharged smoothly. When the airflow passes through the second volute tongue, part of it flows outward and part of it enters the right volute. The gap between the right volute and the impeller gradually decreases from top to bottom. The airflow will gradually be pressed into the impeller and form an eccentric vortex. The eccentric vortex is between the second volute tongue and the minimum position of the rotating volute and the impeller. The rotating volute can effectively prevent the airflow entering the bottom of the heat exchanger from flowing to the lower air port. At this time, the lower air port is the air inlet and the upper air port is the air outlet.

[0134] In the second state of downflow, the rotating volute and the air guide plate rotate, the second lower air guide plate rotates until it contacts the rotating volute to form the volute profile, and the spoiler opens. The airflow enters from the upper air port and flows to the lower air port through the crossflow blades. At this time, the fluid at the lower air port has a tendency to flow upward from the left volute driven by the crossflow blades. The spoiler in the open state will block the upward movement of the airflow and press the fluid into the impeller, and form an eccentric vortex in the area between the first volute tongue and the end of the spoiler, so that the internal airflow has only a tendency to flow downward. At this time, the lower air port is the air outlet and the upper air port is the air inlet.

[0135] The action of the air guide plate is as follows: during the upward and downward air outlet processes, the air guide plate has a greater impact on the inlet and outlet resistance and air volume.

[0136] During the upper air outlet process, in order to ensure that the resistance of the upper air outlet is greater than a certain value of the lower air outlet to ensure stable air outlet, the lower air outlet air guide plate needs to be opened to Fig.12 The position shown is to increase the lower air inlet as much as possible and reduce resistance; while the upper air outlet air guide plate plays a role in guiding the wind.

[0137] During the downwind flow, the downwind resistance should be greater than the upwind resistance by a certain value to stabilize the flow. The upwind guide plate is opened to the maximum to minimize the upwind resistance. The second downwind guide plate is connected to the rotating volute to form a complete continuous volute. The first downwind guide plate can be used to sweep the air up and down.

[0138] Under normal conditions, the air conditioner's default cooling mode is bottom-inlet and top-outlet, to ensure that cold air gradually settles from the top to the bottom of the room. The bottom air is sucked in by the downwind outlet, forming an air circulation in the room to prevent cold air from accumulating at the bottom.

[0139] In heating mode, the default is the anti-direct blowing mode. The hot air is blown out vertically downward from the air outlet, and the upper air inlet absorbs the air above the room, so that the airflow in the room forms a large circulation throughout the house, preventing hot air from accumulating on the top.

[0140] When the machine is turned off, the air guide plate is closed and all rotating plates are retracted into place.

[0144] In one embodiment, the determination unit 100 is specifically used to: if the current working mode is the cooling mode, determine that the required air supply state is the first state of upward air supply; if the current working mode is the heating mode, determine that the required air supply state is the second state of downward air supply.
