[0059] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0060] 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 indicate the relationship between the various embodiments and / or settings discussed in itself. In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can appreciate the applicability of other processes and / or the use of other materials.

[0061] Below, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the first aspect of the present application is described.

[0062] like Figure 1-Figure 3 As shown, the air conditioner 100 includes: a housing component 1, an air supply component 2, a spoiler component 3 and an air guide component 4. The housing component 1 has an air outlet 11, the air supply component 2 is arranged in the housing component 1 and includes an air duct component 21 and a wind wheel 22, the air duct component 21 defines an air duct 210 communicating with the air outlet 11, and the wind wheel 22 is arranged in the air duct 210 to enable the air duct 210 to supply air to the air outlet 11. The spoiler component 3 includes a driving device 31 and a spoiler 32, at least part of which is arranged in the air duct 210, and the driving device 31 includes a resonant actuator 311, which is connected to the spoiler 32 to drive the spoiler 32 to resonate and realize turbulence. The wind guide component 4 is arranged in the air duct 210 and / or the air outlet 11, and is used to adjust the air outlet direction of the air outlet 11, wherein the spoiler 32 is located downstream of the wind wheel 22, and the wind guide component 4 is located downstream of the spoiler 32.

[0063] It is worth noting that the resonant actuator 311 is suitable for driving the spoiler 32 to resonate and achieve spoiler, and the word "suitable for" means that the resonant actuator 311 has the function of driving the spoiler 32 to resonate and achieve spoiler, but is not limited to having only this function. For example, in other embodiments of the present application, the resonant actuator 311 also has the function of driving the spoiler 32 to perform other movements.

[0064] It is understandable that "resonance" is also called "resonance". When the frequency of the driving force is equal to the natural frequency of the system, the amplitude of the forced vibration of the system is the largest. This phenomenon is called resonance. When the frequency of the external force is the same as or very close to the natural oscillation frequency of the system, the amplitude of the oscillation system increases sharply under the action of periodic external forces. The frequency when resonance occurs is called "resonance frequency". In addition, "natural frequency" is also called "natural frequency". When an object vibrates freely, its displacement changes with time according to the sine or cosine law. The frequency of vibration has nothing to do with the initial conditions, but is only related to the inherent characteristics of the system (such as mass, shape, material, etc.). It is called the natural frequency, and its corresponding period is called the natural period. The natural frequency has nothing to do with external excitation and is an inherent property of the structure. Regardless of whether the structure is excited by the outside world, the natural frequency of the structure exists. It is just that when there is external excitation, the structure produces a vibration response according to the natural frequency. In addition, "free vibration" refers to the vibration of a mechanical system after removing the excitation or constraint. The vibration is maintained only by its elastic restoring force. When there is damping, the vibration gradually decays. The frequency of free vibration is only determined by the physical properties of the system itself, which is called the natural frequency of the system. In simple terms, when the excitation frequency of the resonant actuator 311 is the same as or close to the natural frequency of the spoiler 32, the resonance effect is utilized. The vibration generated by the spoiler 32 is called resonance. The amplitude of the spoiler 32 will increase sharply, so that the spoiler 32 can vibrate the spoiler more effectively, thereby accelerating the flow of air, improving the air supply wind feeling of the air duct 210, and improving the comfort of air supply.

[0065] It can be understood that “upstream” refers to the components that the airflow passes through first, and “downstream” refers to the components that the airflow passes through later, that is, the airflow passes through the wind wheel 22, the spoiler component 3 and the wind guide component 4 in sequence.

[0066] For example, when the wind wheel 22 triggers the air flow, the wind wheel 22 sends the air flow along the air duct 210 to the spoiler component 3. If the spoiler component 3 is working and the spoiler 32 resonates, the wind feeling can be improved by the disturbance of the air flow by the spoiler 32, and then the air supply direction can be adjusted through the air guide component 4, so that the air flow is sent out from the air outlet 11 of the air conditioner 100 according to the air guide direction, and then the comfortable airflow is delivered to the position required by the user, thereby improving the user's comfort while meeting the temperature adjustment requirements.

[0067] For another example, when the wind wheel 22 triggers the air flow, the wind wheel 22 sends the air flow along the air duct 210 to the spoiler component 3. If the spoiler component 3 is not working, the spoiler 32 has no effect on the air flow. The air supply direction is then adjusted through the air guide component 4, so that the air flow is sent out from the air outlet 11 of the air conditioner 100 in the air guide direction, and then the air flow is delivered to the position required by the user.

[0068] In the related art, the horizontally mounted air conditioner is provided with a plurality of small swing blades arranged in a transverse direction at the air outlet to achieve left and right swinging wind, and a long air guide plate is provided on the outside of the small swing blade to achieve up and down swinging wind. In order to meet the comfort requirements of the air conditioner, micro holes are usually provided on the long air guide plate. When the long air guide plate blocks the air outlet, the air flow is sent out from the micro holes on the long air guide plate, thereby reducing the wind feeling. However, although this air outlet method reduces the wind feeling, the air outlet resistance is large and the air outlet volume is low, which makes it difficult to meet the temperature regulation requirements. Moreover, the airflow sent out through the air dispersion holes on the long air guide plate is not directional, and it is difficult to transport it to the user's required position for temperature regulation.

[0069] The air conditioner 100 of the embodiment of the present application reduces the wind feeling by the spoiler of the spoiler 32, does not need to block the air outlet 11, has relatively low wind resistance, has a good improvement effect on the attenuation of the air volume, makes the air volume of the air supply more sufficient, and can better take into account the temperature adjustment requirements. Moreover, the air guide component 4 downstream of the spoiler component 3 can be used to guide the airflow after the wind feeling is adjusted to the position required by the user, so as to meet the temperature adjustment requirements of the required position, and at the same time ensure the wind feeling comfort experience of the required position, so that the temperature adjustment requirements and the wind feeling comfort experience of the required position can be taken into account.

[0070] In summary, according to the air conditioner 100 of the embodiment of the present application, the resonance of the spoiler 32 in the spoiler component 3 can be used to disturb the airflow to reduce the wind feeling. This method of reducing the wind feeling does not need to block the air outlet 11, thereby avoiding the problem of large wind resistance and can better ensure the air volume. At the same time, the wind guide component 4 downstream of the spoiler component 3 can be used to guide the airflow after adjusting the wind feeling to the desired position, which can improve the user's comfort experience while meeting the temperature adjustment requirements of the desired position, that is, achieving the goal of both meeting the temperature adjustment requirements of the desired position and the wind comfort experience.

[0071] In some embodiments, when the spoiler component 3 is a piezoelectric actuator or the like, the amplitude and frequency of the spoiler 32 can be changed by adjusting the input current, so that different wind feeling effects can be further adjusted.

[0072] In addition, it is worth noting that in the embodiments of the present application, the spoiler component 3 may only have the function of making the spoiler 32 resonate, or may not only have this function. For example, in some embodiments of the present application, the spoiler component 3 may also have the function of making the spoiler 32 deflect a set angle to achieve directional wind guidance. It should be noted that the set angle here does not refer to a certain angle, but may be certain angles, such as some angle values ​​within a certain angle range, so as to meet the adjustment of different air supply angles. At this time, when the wind wheel 22 triggers the air flow, the wind wheel 22 sends the air flow along the air duct 210 to the spoiler component 3. If the spoiler component 3 works and the spoiler 32 deflects in a directional manner, the air supply direction can be adjusted by the spoiler 32 disturbing the air flow, and the air supply direction can be further adjusted by the air guide component 4, so that the air outlet of the air conditioner 100 can be more effectively sent out in the wind guide direction, and then the air flow is delivered to the position required by the user. For example, when the resonant actuator 311 is a piezoelectric actuator described below, the piezoelectric actuator drives the spoiler 32 to resonate when an alternating signal is applied thereto, and drives the spoiler 32 to deflect by a set angle when a constant signal or a pulse signal is applied thereto.

[0073] In some embodiments of the present application, Figure 2-Figure 4 As shown, there are multiple spoilers 32 and they are arranged at intervals along the length direction X of the air outlet 11, and the thickness direction of the spoiler 32 is consistent with the length direction of the air outlet 11. Therefore, when the spoiler 32 is not needed to tamper, the spoiler 32 can be parallel to the airflow direction of the corresponding position in the air duct 210 (i.e., the position where the spoiler 32 is set), thereby reducing the interference of the spoiler 32 on the airflow flow, reducing wind resistance, and ensuring the air volume; and when the spoiler 32 is needed to tamper and reduce the wind feeling, each spoiler 32 can be driven to vibrate back and forth along the length direction X of the air outlet 11 to break up the airflow. Since the force direction of the broken airflow is the length direction X of the air outlet 11, the airflow can continue to flow smoothly toward the downstream wind guide component 4 after being broken up, instead of hitting the wall surfaces on both sides of the width of the air duct 210, thereby effectively improving the problem of air volume attenuation.

[0074] In some embodiments of the present application, Figure 2 and Figure 3As shown, the spoiler 32 includes a blade portion 321 and a connecting portion 322, the blade portion 321 includes a first end 32a and a second end 32b, the first end 32a is connected to the resonant actuator 311 through the connecting portion 322, such as one end of the connecting portion 322 is connected to the resonant actuator 311, the other end of the connecting portion 322 is connected to the first end 32a of the blade portion 321, the second end 32b is an end of the blade portion 321 away from the connecting portion 322, the blade portion 321 extends along the air outlet direction in the direction from the first end 32a to the second end 32b, that is, the connecting direction of the first end 32a and the second end 32b is substantially consistent with the airflow extension direction of the air duct 210 at the position where the spoiler 32 is set, and the blade width of the blade portion 321 gradually increases in the direction from the first end 32a to the second end 32b.

[0075] Thus, the spoiler 32 can have a larger spoiler area, which is conducive to improving the spoiler effect on the airflow. Moreover, since the thickness direction of the spoiler 32 extends along the length direction X of the air outlet 11, so that the surface of the spoiler 32 (i.e., the two side surfaces in the thickness direction) is parallel to the cross section of the wind wheel 22, it can be understood that the air duct 210 is provided with a diffuser section downstream of the wind wheel 22, and on the cross section of the wind wheel 22, the width of the diffuser section gradually increases along the air outlet direction, and the blade width of the spoiler 32 is set to a shape that gradually increases along the air outlet direction, which is conducive to matching the shape of the diffuser section of the air duct 210, so that the spoiler can be realized to a greater extent.

[0076] In some embodiments, the resonant actuator 311 and the spoiler 32 are both arranged in a plurality and in a one-to-one correspondence, thereby achieving the individual resonance of the plurality of spoilers 32. In addition, each resonant actuator 311 can be arranged in the same form, thereby reducing the difficulty of design and control, or at least two resonant actuators 311 can be arranged in different forms, so as to present different spoiler effects by combining different resonant actuators 311 to work.

[0077] In order to meet the comfort requirements of the air conditioner, accelerate the circulation of air in the room, make the heat exchange in the room more uniform, and make the air outlet feel more comfortable, there are some optional solutions. For example, a convex hull structure is installed on the inner side of the air outlet, and the indoor airflow and wind feeling are adjusted by the surface shape of the convex hull structure and the rotation of the convex hull structure in the air duct. However, the convex hull structure installed on the side of the air outlet significantly reduces the air volume of the whole machine, affecting the heat exchange efficiency. The spoiler of the present application does not affect the flow area of ​​the air duct like the convex hull, so the wind resistance is relatively small, which can better reduce the adverse effect on the air volume. For another example, a wind-dispersing rotor blade is installed on the air guide plate of the air conditioner. When the air guide plate blocks the air outlet, the wind-dispersing rotor blade can be driven to rotate, and the airflow passing through the wind-dispersing rotor blade is dispersed to reduce the wind feeling. However, the large wind resistance of the air guide plate is also easy to cause air volume attenuation, and when the wind-dispersing rotor blade is driven to rotate, the rotation speed of the rotor blade is too low (often less than 1Hz), which is actually difficult to effectively adjust the wind feeling. Compared with this solution, the spoiler of the present application does not need to block the air outlet, and has a significant improvement effect on the attenuation of air volume. Moreover, the vibration frequency of the spoiler can be higher, so the effect of reducing the wind can be more obvious. For another example, by changing the motor speed, adjusting the air volume and air speed, and changing the air supply distance, the uniformity of indoor air temperature can be adjusted. However, adjusting the motor speed requires too high motor performance, the motor cost is high, and the noise will often increase with the increase in speed. When the motor drives the fan to run, due to the rapid change in speed, the motor and the fan are easily damaged, the life is greatly reduced, and the reliability is reduced. Compared with this solution, the spoiler of the present application will not increase the requirements for motor performance, and can avoid causing the above-mentioned technical problems at the motor.

[0078] In some embodiments, Figure 2-Figure 9 As shown, the air guide component 4 includes a first air guide assembly 5, and the first air guide assembly 5 includes an air guide blade 51 arranged in the air duct 210. The air guide blade 51 is multiple and is arranged at intervals along the length direction X of the air outlet 11. The air guide blade 51 can be rotatably arranged and the air guide blade 51 rotates relative to the rotation axis of the air duct 210 (such as Figure 3 The first rotation axis L1) shown in the figure is perpendicular to the length direction X of the air outlet 11, or the rotation axis of the guide vane 51 is parallel to the cross-section S of the air outlet 11, so that the wind direction along the length direction X of the air outlet 11 can be adjusted by rotating the guide vane 51.

[0079] Therefore, according to the embodiment of the present application, the air guide component 4 includes multiple air guide blades 51, which can adjust the air supply angle of the airflow in the length direction X of the air outlet 11, thereby increasing the air supply range of the airflow in the length direction X of the air outlet 11.

[0080] It is worth noting that the type of the air conditioner 100 in the embodiment of the present application is not limited, for example, it can be a split air conditioner or an integrated air conditioner, the split air conditioner can include a horizontal air conditioner, a vertical air conditioner, a floor-standing air conditioner, etc., and the integrated air conditioner can include a kitchen air conditioner, a window air conditioner, etc. After the type of the air conditioner 100 is determined, those skilled in the art can know the optional setting scheme of the air outlet 11. To simplify the description, this article takes the air conditioner 100 as an example of a horizontal air conditioner for description.

[0081] When the air conditioner 100 is a horizontal air conditioner, the length direction X of the air outlet 11 is the left-right direction, and the width direction of the air outlet 11 is the up-down direction (such as the up-down vertical direction or the up-down inclined direction). Figure 4 and Figure 5 When the angle between the air guide blade 51 and the cross section S of the air outlet 11 is 0°, air can be delivered forward; Figure 6 and Figure 7 When the angle a between the guide blade 51 and the cross section S of the air outlet 11 is 0° to 90° (i.e., an acute angle to the left), air can be delivered to the left front; Figure 8 and Fig. 9 When the angle a between the guide blade 51 and the cross section S of the air outlet 11 is -90° to 0° (i.e., an acute angle to the right), air can be delivered to the right front. It can be understood that the cross section S of the air outlet 11 is perpendicular to the length direction X of the air outlet 11.

[0082] In the embodiment of the present application, the rotation angle range of the air guide blade 51 is not limited. For example, the rotation angle range of the air guide blade 51 is: -90° to 90°, that is, the angle a between the air guide blade 51 and the cross section S of the air outlet 11 can be any value between -90° and 90° (for example Figure 7 and Fig. 9 As shown). Thus, the air guide blade 51 can have a larger air guide adjustment range.

[0083] In some embodiments, Figure 4 As shown, when there are multiple spoilers 32 and they are spaced apart along the length direction X of the air outlet 11, and the thickness direction of the spoiler 32 is consistent with the length direction of the air outlet 11, and at the same time, there are multiple guide blades 51 and they are spaced apart along the length direction X of the air outlet 11, and the guide blades 51 are rotatable and the rotation axis is perpendicular to the length direction X of the air outlet 11, the airflow spoiled by the spoiler 32 can easily enter between two adjacent guide blades 51, and be sent out from the air outlet 11 after being guided in the direction, thereby further reducing the wind resistance.

[0084] In some embodiments, Figure 4As shown, when there are multiple spoilers 32 and they are spaced apart along the length direction X of the air outlet 11, and the thickness direction of the spoiler 32 is consistent with the length direction of the air outlet 11, and at the same time, there are multiple air guide blades 51 and they are spaced apart along the length direction X of the air outlet 11, and the air guide blades 51 are rotatably arranged and the rotation axis is perpendicular to the length direction X of the air outlet 11, it can be arranged that: the number of spoilers 32 can be greater than the number of air guide blades, and the spacing between two adjacent spoilers 32 is smaller than the spacing between two adjacent air guide blades, so that the effect of the spoiler 32 on improving the wind feeling can be further enhanced.

[0085] In some embodiments, Figure 4 and Fig.11 As shown, when there are multiple spoilers 32 and they are spaced apart along the length direction X of the air outlet 11, and the thickness direction of the spoiler 32 is consistent with the length direction of the air outlet 11, and at the same time, there are multiple guide blades 51 and they are spaced apart along the length direction X of the air outlet 11, and the guide blades 51 are rotatable and the rotation axis is perpendicular to the length direction X of the air outlet 11, it can be set that: the area of ​​the spoiler 32 is larger than the area of ​​the guide blade 51, so that the effect of the spoiler 32 on improving the wind feeling can be further enhanced.

[0086] For example, when it is necessary to set the area of ​​the spoiler 32 to be larger than the area of ​​the guide blade 51, the spoiler 32 can be selected to be set to the above-mentioned shape in which the blade width gradually increases in the direction from the first end 32a to the second end 32b, so as to facilitate the design of enlarging the area of ​​the spoiler 32, but the present application is not limited to this. The shape of the spoiler 32 can also be set to other forms to make the area of ​​the spoiler 32 larger than the area of ​​the guide blade 51.

[0087] In some embodiments, Figure 4 and Fig.11 As shown, when there are multiple spoilers 32 and they are spaced apart along the length direction X of the air outlet 11, and the thickness direction of the spoiler 32 is consistent with the length direction of the air outlet 11, and at the same time, there are multiple air guide blades 51 and they are spaced apart along the length direction X of the air outlet 11, and the air guide blades 51 are rotatably arranged and the rotation axis is perpendicular to the length direction X of the air outlet 11, it can be arranged that: the number of spoilers 32 can be greater than the number of air guide blades, and the spacing between two adjacent spoilers 32 is smaller than the spacing between two adjacent air guide blades, and at the same time, it is arranged that: the area of ​​the spoiler 32 is greater than the area of ​​the air guide blade 51, so that the effect of the spoiler 32 on improving the wind feeling can be further enhanced.

[0088] Exemplarily, the number of spoilers 32 can be 2-4 times the number of air guide blades, for example 2 times, 3 times, 4 times, etc., and the spoilers 32 are basically evenly spaced apart, so that the number of spoilers 32 can be large, but not too many, so that the number of spoilers 32 is relatively large, and at the same time the spacing between spoilers 32 may not be too small, so that even if the area of ​​the spoiler 32 is large, it can have a large amplitude without collision, thereby effectively improving the wind feel.

[0089] In some embodiments, Figure 2 and Figure 3 As shown, when the air conditioner 100 is turned off, the air guide blade 51 rotates to be completely stored in the return air duct 210. Fig.11 and Fig.13 As shown, in the air guiding state, the air guide blade 51 of the first air guide component 5 rotates to partially extend outside the air outlet 11. Thus, the air guide blade 51 can avoid occupying the space outside the shell component 1 in the storage state, and the air guide blade 51 can partially extend outside the air outlet 11 in the air guiding state, so as to increase the area of ​​the air guide blade 51, extend the air flow guiding distance of the air guide blade 51, and further increase the air guiding effect, for example, it is beneficial to increase the air outlet distance, or to increase the air outlet range, etc. For example, it can also be set so that the area of ​​the air guide blade 51 is larger than the area of ​​the spoiler 32.

[0090] In some embodiments, Fig.14 and Fig.15 As shown, the first air guide assembly 5 further includes a connecting rod 52, which extends along the length direction X of the air outlet 11, and the connecting rod 52 is pivotally connected to the plurality of air guide blades 51, respectively, so that the plurality of air guide blades 51 connected to the connecting rod 52 rotate synchronously. Thus, the plurality of air guide blades 51 can be moved synchronously, thereby simplifying the adjustment of the rotation angles of the plurality of air guide blades 51.

[0091] For example, combined with Figure 3 and Fig.17 The guide vane 51 has a rotating shaft 511 and a connecting shaft 512 arranged in parallel with the axis. The guide vane 51 is rotatably connected to the air duct assembly 21 via the rotating shaft 511 to achieve the guide vane 51 relative to the air duct assembly 21 around the rotating axis (such as Figure 3 The connecting rod 52 is pivotally connected to the connecting shaft 512 so that the air guide vane 51 is rotatable relative to the connecting rod 52 around the axis of the connecting shaft 512 (as shown in FIG. Figure 3 The second rotation axis L2) shown in FIG. 1 is rotatable.

[0092] It is worth noting that the first air guide assembly 5 may include only one connecting rod 52, thereby further simplifying the design and control and reducing the cost. Alternatively, it may also include a plurality of connecting rods 52 arranged along the length direction of the air outlet 11, each connecting rod 52 connecting at least two air guide blades 51, thereby reducing the number of air guide blades 51 on each connecting rod 52, and making the air guide directions of the air guide blades 51 on different connecting rods 52 adjustable separately, so as to combine more different air supply adjustment schemes. For example, the plurality of guide blades in the first air guide assembly 5 are evenly distributed on the plurality of connecting rods 52, such as when two connecting rods 52 are provided, one connecting rod 52 is provided with half of the total number of air guide blades 51, these air guide blades 51 are a group, presenting one air guide direction (for example, all swing to the left front), and the other connecting rod 52 is also provided with half of the total number of air guide blades 51, these air guide blades 51 are another group, presenting another air guide direction (for example, all swing to the right front).

[0093] It is worth noting that there is no limit to the method of driving the guide blades 51 to rotate. For example, in some embodiments, the first air guide assembly 5 may include a motor 53, and the motor 53 drives the connecting rod 52 to move, so as to pull multiple guide blades 51 to rotate together through the connecting rod 52. Alternatively, the motor 53 can also drive one of the guide blades 51 to rotate, and when the guide blade 51 rotates, it will drive the remaining guide blades 51 on the connecting rod 52 to rotate together through the connecting rod 52.

[0094] For example, Fig.14 and Fig.15 In the illustrated embodiment, the first air guide assembly 5 further includes a motor 53 and a crank 54, the two ends of the crank 54 are pivotally connected to the output shaft of the motor 53 and the end of the connecting rod 52 respectively, and the motor 53 drives the connecting rod 52 to move through the crank 54, so that the connecting rod 52 pulls the plurality of air guide blades 51 to rotate synchronously. Thus, the arrangement of the crank 54 and the motor 53 does not occupy the space on the air flow path, thereby reducing wind resistance and ensuring air volume. In addition, the driving scheme is relatively simple, easy to set up, easy to control, low in cost, and reliable in driving effect.

[0095] For example, when the first air guide component 5 is in a state of sending air forward (for example Figure 4 and Figure 5 if the motor 53 drives the crank 54 to rotate clockwise, the crank 54 pulls the connecting rod 52 to move to the left, and the connecting rod 52 pulls the multiple wind guide blades 51 connected thereto to swing to the left (for example Figure 6 and Figure 7 If the motor 53 drives the crank 54 to rotate counterclockwise, the crank 54 pulls the connecting rod 52 to move to the right, and the connecting rod 52 pulls the multiple wind guide blades 51 connected thereto to swing to the right (for example Figure 8 and Fig. 9The state shown in ), thereby, the rotation and swinging wind at multiple angles such as left, right, and front can be realized.

[0096] For example, Fig.16 and Fig.17 In the illustrated embodiment, the first air guide assembly 5 also includes a motor 53 and a gear mechanism 55. One of the multiple air guide blades 51 connected to the connecting rod 52 is a set air guide blade 510. The gear mechanism 55 is transmitted and cooperated between the motor 53 and the set air guide blade 510. The motor 53 drives the set air guide blade 510 to rotate through the gear mechanism 55. The set air guide blade 510 drives the remaining air guide blades 51 connected to the connecting rod 52 to rotate synchronously through the connecting rod 52.

[0097] In the above technical solution, the motor 53 and the gear mechanism 55 do not occupy the space on the length side of the connecting rod 52, which is conducive to reducing the space occupied by the first air guide component 5 in the length direction X of the air outlet 11, so that the length of the air outlet 11 can be increased, and the air outlet range in the length direction X of the air outlet 11 can be further improved. In addition, the driving scheme is relatively simple, easy to set up, easy to control, low in cost, and reliable in driving effect. It is worth noting that in order to avoid obstruction to the flow of air, the motor 53 and the gear mechanism 55 can be set outside the air duct 210.

[0098] As described above, when the motor 53 rotates, the gear mechanism 55 can be used to drive the setting air guide vane 510 to rotate, so that the setting air guide vane 510 drives the other air guide vanes 51 on the connecting rod 52 to rotate synchronously, for example, in combination with Fig.18 , the motor 53 drives the setting air guide blade 510 to rotate rightward, and the remaining air guide blades 51 are also driven by the connecting rod 52 to rotate rightward to achieve rightward swinging wind; combined Fig.19 , the motor 53 drives the set air guide blade 510 to rotate forward, and the remaining air guide blades 51 are also driven by the connecting rod 52 to rotate forward to achieve forward swinging wind; Fig. 20 The motor 53 drives the set air guide blade 510 to rotate to the left, and the other air guide blades 51 are also driven by the connecting rod 52 to rotate to the left to achieve leftward swinging. In this way, the air can also be swung at multiple angles such as left, right, and front.

[0099] It is worth noting that the specific structure of the gear mechanism 55 is not limited. Fig.16 and Fig.17As shown, the gear mechanism 55 may include a first gear 551, a second gear 552 and a third gear 553. The first gear 551 is coaxially arranged on the output shaft of the motor 53, the third gear 553 is coaxially arranged on the rotating shaft 511 of the guide vane 51, and the second gear 552 is meshed with the first gear 551 and the second gear 552 respectively. In this way, the motor 53 can drive the first gear 551 to rotate, the first gear 551 drives the second gear 552 to rotate, and the second gear 552 drives the third gear 553 to rotate, thereby causing the guide vane 51 to rotate.

[0100] Of course, the present application is not limited thereto. For example, in other embodiments of the present application, the gear mechanism 55 may also include two gears (for example, only the first gear 551 and the third gear 553, and the first gear 551 and the third gear 553 are meshed for transmission) or may include more than three gears. Thus, different adjustment effects can be obtained by adjusting the number of gears and the gear transmission ratio, thereby improving the flexibility of the design.

[0101] In some embodiments of the present application, Figure 3 , Figure 10-13 As shown, the air guide component 4 includes a second air guide assembly 6, and the second air guide assembly 6 includes at least one air guide plate 60, which extends along the length direction X of the air outlet 11, that is, the length direction of the air guide plate 60 is consistent with the length direction X of the air outlet 11, and the air guide plate 60 can be rotatably arranged and the rotation axis of the air guide plate 60 relative to the air duct 210 (such as Fig.10 The third rotation axis L3 and the fourth rotation axis L4 shown in FIG. 1 are parallel to the length direction X of the air outlet 11. When the air conditioner 100 is turned off, the air guide plate 60 is located on the outer side of the air guide blade 51 (for example, Figure 3 status shown).

[0102] Thus, the air guide plate 60 can be used to achieve wind direction adjustment along the width direction of the air outlet 11. For example, when the air conditioner 100 is a horizontally mounted air conditioner, the length direction X of the air outlet 11 is the left-right direction, and the width direction of the air outlet 11 is the up-down direction (such as the up-down vertical direction or the up-down inclined direction). The air guide plate 60 rotates around the horizontal axis to achieve up-down swing wind adjustment, thereby adjusting the air supply angle in the up-down direction to increase the air supply range of the airflow in the width direction of the air outlet 11.

[0103] In addition, since the air guide plate 60 is located outside the air guide blade 51 when the air conditioner 100 is turned off, the air guide plate 60 can shield and protect the air guide blade 51. Furthermore, if the air conditioner 100 is turned off, the air guide blade 51 can be rotated to be completely stored in the return air duct 210, thereby reducing the risk of collision and interference between the air guide blade 51 and the air guide plate 60, and protecting both from damage.

[0104] For example, in some embodiments, there are two air guide plates 60, namely a first air guide plate 61 and a second air guide plate 62, and the width of the second air guide plate 62 is greater than the width of the first air guide plate 61. Figure 3 As shown, when the air conditioner 100 is turned off, the second air guide plate 62 blocks the air outlet 11, and the first air guide plate 61 is located inside the second air guide plate 62. At this time, the second air guide plate 62 can play the role of opening and closing the door, thereby eliminating the need to set up an opening and closing door and reducing costs. In addition, the first air guide plate 61 is located inside the second air guide plate 62, and the air guide blades 51 are located inside the first air guide plate 61, which can reasonably utilize space and make the overall appearance neat.

[0105] like Figure 10-13 As shown, when the air conditioner 100 is in working state, the first air guide plate 61 and the second air guide plate 62 are respectively disposed on both sides of the width of the air outlet 11, that is, the first air guide plate 61 is disposed close to one side of the width of the air outlet 11 (at this time, the first air guide plate 61 can be located inside the air outlet 11 or can extend outside the air outlet 11), and the second air guide plate 62 is disposed close to the other side of the width of the air outlet 11 (at this time, the second air guide plate 62 can be located inside the air outlet 11 or can extend outside the air outlet 11). Thus, the two air guide plates 60 can adjust the air supply direction separately from both sides of the width of the air outlet 11, which is conducive to combining more different air supply adjustment schemes.

[0106] For example, when the air conditioner 100 is a horizontal air conditioner, the length direction X of the air outlet 11 is the left-right direction, the width direction of the air outlet 11 is the up-down direction (such as the up-down vertical direction or the up-down inclined direction), at least a portion of the first air guide plate 61 is located inside the air outlet 11 and rotates, the second air guide plate 62 is located outside the air outlet 11 as a whole and rotates, and the rotation axis of the first air guide plate 61 (such as Fig.10 The third rotation axis L3 shown in FIG. 1 is higher than the rotation axis of the second air guide plate 62 (as shown in FIG. Fig.10 ), after the air conditioner 100 is turned on, the first air guide plate 61 rotates to the upper part of the air outlet 11, and the second air guide plate 62 rotates to the lower part of the air outlet 11, and the first air guide plate 61 and the second air guide plate 62 rotate separately around their respective rotation axes, thereby adjusting the air supply angle and air supply range in the up and down directions.

[0107] For example, combined with Fig.10 and Fig.11 As shown, in the cooling state, the first air guide plate 61 is rotated until the line connecting the two ends of the width of the first air guide plate 61 intersects the horizontal line at a first angle γ1, combined with Fig.12 and Fig.13As shown, in the heating state, the first air guide plate 61 is rotated until the line connecting the two ends of the width of the first air guide plate 61 intersects the horizontal line at a second angle γ2, and the second angle γ2>the first angle γ1, that is, in the heating state, the angle at which the first air guide plate 61 is rotated downward is relatively large, thereby achieving the effect of pressing the hot air downward, so that the hot air flow can be blown toward the user more, and in the cooling state, the angle at which the first air guide plate 61 is rotated downward is relatively small, thereby achieving the effect of raising the cold air downward, improving the direct blowing of cold air to the user, and improving comfort.

[0108] In the embodiment of the present application, the rotation angle range of the air guide plate 60 is not limited. For example, the rotation angle range of the second air guide plate 62 is: 0°~180°. When the air conditioner 100 is turned off, the second air guide plate 62 closes the air outlet 11. At this time, the second air guide plate 62 is in the initial position. The angle β of the second air guide plate 62 at this time is defined as 0°. During the operation of the air conditioner 100, the second air guide plate 62 can be rotated 0°~180° relative to the initial position, so that the angle β of the second air guide plate 62 (for example Fig.11 As shown in the figure, the second air guide plate 62 can be adjusted to any value between 0° and 180°. Thus, the second air guide plate 62 can have a larger air guide adjustment range.

[0109] In some embodiments, the air guide blades 51 of the first air guide assembly 50 may be rotatably connected to the upper end of the air outlet 11 , or the lower end of the air outlet 11 , or may be rotatably connected to the air guide plate 60 .

[0110] It is worth noting that in some embodiments of the present application, the air guide component 4 may include only the first air guide component 5 but not the second air guide component 6, or the air guide component 4 may include only the second air guide component 6 but not the first air guide component 5, which will not be described in detail here. In addition, it is worth noting that the specific type of the resonant actuator 311 in the embodiment of the present application is not limited, for example, it may include at least one of a piezoelectric actuator, an electrostrictive actuator, a magnetostrictive actuator, a memory alloy actuator, a mechanical actuator, a servo actuator, and an electrorheological fluid actuator.

[0111] In some embodiments of the present application, the resonant actuator 311 is a piezoelectric actuator, which uses the inverse piezoelectric effect of piezoelectric materials such as piezoelectric sheets to reciprocate and deform, drive the spoiler to resonate, and achieve the purpose of spoiler. Wherein, the piezoelectric sheet is a sheet formed by a piezoelectric material, such as a piezoelectric film. The piezoelectric film is a flexible, lightweight, high-toughness plastic film that can be made into objects of various thicknesses and large areas. The piezoelectric film can be driven by alternating current to produce an inverse piezoelectric effect, thereby driving the spoiler to resonate. In other words, an alternating voltage is applied to the polarization direction of the piezoelectric material piece, and at this time, the piezoelectric material piece will produce periodic mechanical deformation in a certain direction. When the excitation frequency of the piezoelectric material piece is equal to or close to the natural frequency of the spoiler, resonance (or resonance) occurs. At this time, the amplitude of the spoiler will increase sharply, so that the spoiler can be more effectively spoiled and improve the wind sense of the wind.

[0112] For example, in some embodiments, the resonant actuator 311 is a piezoelectric actuator. In this case, the piezoelectric actuator can be arranged at the connection portion of the spoiler, and the resonant actuator can be a piezoelectric material and located on one side of the thickness of the spoiler, or the resonant actuator can also be two piezoelectric materials and located on both sides of the thickness of the spoiler, etc., which can simply and effectively drive the spoiler to move. Wherein, the piezoelectric actuator is configured to drive the spoiler to resonate when an alternating signal is applied, and to drive the spoiler to deflect a set angle when a constant signal or a pulse signal is applied.

[0113] For example, when a constant signal or a pulse signal is applied to both ends of the piezoelectric actuator, the resonant actuator 311 will drive the spoiler 32 to deflect to a relatively fixed angle, presenting a relatively stable wind guide angle, so that the wind direction can be adjusted (or directional wind guide). And by using the matching relationship between the deflection angle of the spoiler 32 and the signal value, by adjusting the signal value, the spoiler 32 can be accurately controlled to deflect to the corresponding fixed wind guide angle, thereby achieving relatively accurate wind direction adjustment.

[0114] For example, when an alternating signal is applied to both ends of the piezoelectric actuator, the resonant actuator 311 will drive the spoiler 32 to reciprocate and resonate, thereby achieving spoiler flow and improving the wind feel of the air. In addition, by changing the size of the alternating signal applied to both ends of the resonant actuator 311, and the signal phase difference of adjacent spoilers 32, etc., the amplitude of the spoiler 32 can be controlled, and the adjustment is more convenient and sensitive. By adjusting the amplitude, vibration direction, phase angle, etc. of the spoiler 32, a variety of wind feelings can be achieved to meet the diversified air supply needs, and achieve a more sensitive and diversified effect of wind feeling adjustment.

[0115] In short, by changing the type of driving signal applied, the wind outlet effect of the spoiler 32 is adjusted. When spoiler is required, the resonant actuator 311 can be used to drive the spoiler 32 to resonate, and when directional wind guidance is required, the resonant actuator 311 can be used to drive the spoiler 32 to deflect, thereby meeting different actual needs of users. For example, the number of resonant actuators 311 and spoilers 32 is the same and they are set one by one.

[0116] In some embodiments, the resonance frequency of the resonant actuator 311 driving the spoiler 32 to resonate is greater than or equal to 1 Hz. Thus, the spoiler 32 can achieve a better spoiling effect and improve the wind feel.

[0117] Further, the resonant frequency of the resonant actuator 311 driving the spoiler 32 to resonate is 1Hz-100Hz. That is to say, a resonant actuator 311 with a resonant frequency of 1Hz-100Hz (e.g., 1Hz, 10Hz, 20Hz, 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, etc.) can be selected as needed to drive the spoiler 32 whose natural frequency matches the resonant frequency to resonate, thereby meeting different requirements for the wind feel of the air outlet. Further, a resonant actuator 311 with a resonant frequency of 10Hz-80Hz (e.g., 10Hz, 20Hz, 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, etc.) can be selected to drive the spoiler 32 whose natural frequency matches the resonant frequency to resonate, thereby meeting different requirements for the wind feel of the air outlet. Of course, the present application is not limited thereto. In other embodiments, the resonant frequency at which the resonant actuator 311 drives the spoiler 32 to resonate may also be greater than 100 Hz, which will not be elaborated herein.

[0118] For the driving motors used in general air conditioners, they can be roughly divided into two types: brushless DC motors and stepper motors. Among them, brushless DC motors are mainly used to drive the fan to move. They can drive the fan to rotate at high speed, but the driving direction is unidirectional and cannot achieve reciprocating motion. When the motor is running at high speed, if the direction is suddenly adjusted, the life and reliability of the motor and the structural parts connected to it cannot be guaranteed. In addition, in terms of technology, it is currently impossible to achieve high-frequency reciprocating rotation of brushless DC motors. Stepper motors are usually used to drive the movement of components such as air guide plates, swing blades, and connecting rod mechanisms. Stepper motors can drive components to reciprocate, but relative to the resonant frequency, the driving frequency is very low. The general reciprocating frequency is about 0.1Hz (about 5 to 6 reciprocating movements per minute), which is about two orders of magnitude lower than the resonant frequency (1Hz-100Hz). Therefore, brushless DC motors and stepper motors used in general air conditioners cannot drive the spoiler 32 to resonate with a resonant frequency greater than 1Hz, and the spoiler 32 cannot effectively spur the air to improve the wind feel.

[0119] For example, in some embodiments, the resonant actuator 311 includes an electrostrictive actuator, which drives the spoiler 32 to resonate through the electrostrictive effect. Specifically, the electrostrictive effect refers to the phenomenon that a dielectric undergoes elastic deformation in an electric field. This phenomenon can be explained as follows: when a dielectric is placed in an electric field, its molecules are polarized, and along the direction of the electric field, the positive pole of one molecule is connected to the negative pole of another molecule. Because the positive and negative poles attract each other, the entire dielectric shrinks in this direction until the elastic force inside it is balanced with the electrical attraction. In short, the electrostrictive material can be connected to the spoiler 32, and the electrostrictive material can be driven to deform by alternating current, thereby driving the spoiler 32 to resonate.

[0120] In addition, it should be noted that the difference between the electrostrictive effect and the inverse piezoelectric effect is that the inverse piezoelectric effect is a linear response effect of the first order term, which can only appear in solid dielectrics without a symmetry center. The piezoelectric constant is a third-order tensor; the physical parameter describing the electrostrictive effect of anisotropic dielectrics is a fourth-order tensor. Only the electrostrictive effect appears in non-piezoelectric dielectrics; the piezoelectric effect and the electrostrictive effect appear simultaneously in piezoelectric bodies. Generally, the strain caused by the electrostrictive effect is several orders of magnitude smaller than the inverse piezoelectric effect of piezoelectric bodies.

[0121] For example, in some embodiments, the resonant actuator 311 includes a magnetostrictive actuator, which drives the spoiler 32 to resonate through the magnetostrictive effect. Specifically, the magnetostrictive effect refers to the ferromagnetic material whose size changes significantly when the object is magnetized in a magnetic field or when the current passing through the coil changes or the distance from the magnet changes. It is usually called a ferromagnetic material. Its size change is much greater than that of the current magnetostrictive materials such as ferrite, and the energy generated is also large, so it is called a giant magnetostrictive material.

[0122] Since the magnetostrictive material changes its length under the action of a magnetic field, it can be displaced to do work or can be repeatedly stretched and shortened under the action of an alternating magnetic field, thereby generating vibrations. This material can convert electromagnetic energy (or electromagnetic information) into mechanical energy. In short, the magnetostrictive material can be connected to the spoiler 32, and the magnetostrictive material can be deformed by the alternating magnetic field, thereby driving the spoiler 32 to resonate.

[0123] For example, in some embodiments, the resonant actuator 311 includes a memory alloy actuator, which drives the spoiler 32 to resonate through the deformation of the shape memory alloy. Specifically, shape memory alloy (Shape Memory Alloys): SMA for short, can undergo martensitic phase transformation under the drive of an external field (temperature field, stress field, magnetic field, etc.) and then present shape memory effect and superelasticity, output force and displacement to the outside, and is an advanced intelligent material that integrates temperature perception and intelligent drive. It has unique shape memory effect, phase change pseudoelasticity and other characteristics, and is widely used in aerospace, medical equipment, mechanical electrical appliances and other fields. Shape memory alloy has three characteristics: large deformation; large degree of freedom in displacement direction; displacement can occur rapidly. Therefore, it has the characteristics of large displacement, high power-to-weight ratio, rapid displacement and free direction. It is particularly suitable for small load, high speed, high precision robot assembly operations, microscope sample moving devices, reactor drive devices, medical endoscopes, artificial hearts, detectors, protectors and other products. In short, the shape memory alloy can be connected to the spoiler 32, and the temperature field can be changed by heating or cooling to drive the spoiler 32 to resonate.

[0124] For example, in some embodiments, the resonant actuator 311 includes an electrorheological fluid actuator, which drives the spoiler 32 to resonate by electro-induced electrorheological fluid deformation. Specifically, electrorheological fluid (abbreviated as ERF) is a kind of intelligent material, and its viscosity changes with the change of the applied electric field strength. When there is no electric field, the electrorheological fluid can flow freely like ordinary liquid, which is basically a Newtonian fluid. When the applied electric field strength reaches a certain value, the property of the electrorheological fluid will change significantly, the liquid viscosity increases and lacks fluidity gradually, and the shear resistance is enhanced, and the liquid is rapidly converted to a solid state, and it is quickly restored to liquid after the electric field is removed. This state change can be realized only in milliseconds, and this conversion is completely reversible. In short, the electrorheological fluid can be connected to the spoiler 32, and the spoiler 32 is driven to resonate by the alternating electric field.

[0125] For example, in some embodiments, the resonant actuator 311 includes a servo actuator, which can be a hydraulic actuator that can convert hydraulic energy from a hydraulic source into mechanical energy, and can also be servo-controlled by a displacement sensor or travel switch provided by the product as needed. It is used to execute the command of the main controller, control the speed, direction, displacement, and force of the load, and at the same time feedback the main controller signal output force, accurate operating position, small size, etc. In short, the servo actuator can be connected to the spoiler 32 to drive the spoiler 32 to resonate.

[0126] For example, in some embodiments, the resonant actuator 311 may also include a mechanical actuator. The mechanical actuator may directly drive the spoiler 32 to resonate through a high-speed motor or through a mechanical mechanism, etc., which will not be elaborated here.

[0127] Below, refer to Figure 1-Figure 15 , describing an air conditioner 100 according to a specific embodiment of the present application.

[0128] The air conditioner 100 of this embodiment is a horizontally mounted air conditioner. The lower part of the front surface of the shell part 1 of the air conditioner 100 has an air outlet 11. The length direction X of the air outlet 11 is the left-right direction, and the width direction of the air outlet 11 is the up-and-down inclined direction.

[0129] The housing part 1 is provided with an air supply part 2 and a spoiler part 3. The air supply part 2 includes an air duct assembly 21 defining an air duct 210 communicating with the air outlet 11, and the air supply part 2 also includes a throughflow-type wind wheel 22 arranged in the air duct 210 and extending axially in the left-right direction. The spoiler part 3 is located downstream of the wind wheel 22, and the spoiler part 3 includes a fixed seat, a piezoelectric actuator and a spoiler 32, the fixed seat is installed on the air duct assembly 21, the spoiler 32 is located in the air duct 210, the piezoelectric actuator is arranged on the fixed seat, the root of the spoiler 32 is connected to the piezoelectric actuator, and the tip of the spoiler 32 extends toward the direction of the air outlet 11. The piezoelectric actuator is a piezoelectric sheet made of piezoelectric material. By using the inverse piezoelectric effect, when an AC voltage is applied to both ends of the piezoelectric material, the piezoelectric material will drive the spoiler 32 at its front end to vibrate back and forth, and the spoiler 32 can drive the flow of surrounding air when vibrating, thereby improving the wind feeling of the air supply. The length direction of the fixing seat extends in the left-right direction, and a plurality of piezoelectric actuators are arranged at intervals in the left-right direction on the fixing seat. Each piezoelectric actuator is connected to a spoiler 32, so that there are multiple spoilers 32 and they are arranged at intervals in the left-right direction, and the thickness direction of each spoiler 32 is in the left-right direction.

[0130] The air conditioner 100 also includes an air guide component 4, which includes a first air guide component 5 and a second air guide component 6. The first air guide component 5 is located downstream of the spoiler component 3, and the second air guide component 6 is located downstream of the first air guide component 5. The spoiler component 3, the first air guide component 5 and the second air guide component 6 work independently and do not affect each other. Among them, the first air guide component 5 includes a plurality of air guide blades 51 arranged in the air duct 210 and spaced apart along the left and right directions. The air guide blades 51 are rotatably arranged and the rotation axis of the air guide blades 51 is perpendicular to the left and right directions, so as to adjust the air supply angle and air supply range in the left and right directions. The first air guide component 5 also includes a connecting rod 52 and a motor 53, wherein the motor 53 is a stepping motor 53, the connecting rod 52 extends along the left and right directions, the connecting rod 52 is pivotally connected to the plurality of air guide blades 51, respectively, so that the plurality of air guide blades 51 connected to the connecting rod 52 rotate synchronously, and the motor 53 drives the connecting rod 52 to move, so as to pull the plurality of air guide blades 51 to rotate together through the connecting rod 52. Alternatively, in combination with Figure 16-Figure 20 The motor 53 can also drive one of the air guide blades 51 to rotate. When the air guide blade 51 rotates, it will drive the other air guide blades 51 on the connecting rod 52 to rotate together through the connecting rod 52.

[0131] The second air guide assembly 6 includes a first air guide plate 61 and a second air guide plate 62. The length directions of the first air guide plate 61 and the second air guide plate 62 are both in the left-right direction. The first air guide plate 61 and the second air guide plate 62 can be rotatably arranged and the rotation axis is in the left-right direction. When the air conditioner 100 is turned off, the first air guide plate 61 is located outside the air guide blade 51, and the second air guide plate 62 is located outside the first air guide plate 61, and the second air guide plate 62 closes the air outlet 11. In addition, when the air conditioner 100 is turned off, the air guide blade 51 rotates clockwise or counterclockwise by a certain angle to be hidden in the air duct 210, so that the first air guide plate 61 and the second air guide plate 62 can be smoothly closed. When the air conditioner 100 is in operation, the first air guide plate 61 rotates upward, and the second air guide plate 62 rotates downward. The first air guide plate 61 rotates to the upper part of the air outlet 11 and is partially located inside the air outlet 11, and the second air guide plate 62 rotates to the lower part outside the air outlet 11. The first air guide plate 61 and the second air guide plate 62 can rotate separately around their respective rotation axes, so as to adjust the air supply angle and air supply range in the up and down directions. At the same time, the air guide blade 51 rotates a certain angle outside the air outlet 11, so that the air guide blade 51 partially extends outside the air outlet 11, so that the windward surface of the air guide blade 51 can be as large as possible to improve the air guiding effect of the air guide blade 51. The rotatable angle range of the air guide blade 51 is -90° to 90°, and the rotatable angle range of the second air guide plate 62 is 0° to 180°.

[0132] Therefore, according to the horizontally mounted air conditioner of the above embodiment, while providing left and right and up and down air guidance through the first air guide component 5 and the second air guide component 6, different air supply wind sensations can be provided by switching the operation of the spoiler component 3 or adjusting the operating frequency or amplitude of the spoiler 32, thereby satisfying the temperature adjustment requirements of the required position while satisfying the user's different comfort experiences.

[0133] Other components of the air conditioner 100 according to the embodiment of the present application, such as a heat exchanger and operations, are known to those skilled in the art and will not be described in detail here.

[0134] Next, a control method of the air conditioner 100 according to an embodiment of the second aspect of the present application is described.

[0135] In this embodiment, if Figure 1-Figure 3 As shown, the air conditioner 100 may include a wind wheel 22, a spoiler component 3 and an air guide component 4, the spoiler component 3 includes a piezoelectric actuator and a spoiler 32, the piezoelectric actuator is connected to the spoiler 32 so as to drive the spoiler 32 to resonate and realize turbulence, the wind wheel 22, the spoiler component 3 and the air guide component 4 are arranged in sequence along the flow direction of the airflow, so that the wind wheel 22 is located upstream of the spoiler component 3, and the air guide component 4 is located downstream of the spoiler component 3.

[0136] Therefore, according to the air conditioner 100 of the embodiment of the present application, the resonance of the spoiler 32 in the spoiler component 3 can be used to disturb the airflow to reduce the wind feeling, and at the same time, the air guide component 4 downstream of the spoiler component 3 can be used to guide the airflow after adjusting the wind feeling to the desired position, which can improve the user's comfort experience while meeting the temperature adjustment requirements of the desired position, that is, achieving the goal of taking into account both the temperature adjustment requirements of the desired position and the wind comfort experience.

[0137] Combination Fig.21 The control method of this embodiment may include the steps of: responding to a comfort cooling mode; obtaining the current ambient temperature (Th) and comparing it with a first set temperature threshold (Ts1); determining that the current ambient temperature (Th) is less than or equal to the first set temperature threshold (Ts1), controlling the air guide component 4 to present a first air guide state, and controlling the wind wheel 22 to operate in a first speed range; determining that the current ambient temperature (Th) is greater than the first set temperature threshold (Ts1), controlling the air guide component 4 to present a second air guide state, controlling the wind wheel 22 to operate in a second speed range, and controlling the spoiler component 3 to start; wherein, the air guide component 4 is close to a straight blowing angle in the second air guide state relative to the first air guide state, and / or the second speed range is greater than the first speed range.

[0138] It is worth mentioning that the cooling mode of the air conditioner 100 in this embodiment may be only the "comfort cooling mode", or may include at least two options of "comfort cooling mode" and "conventional cooling mode". When including at least two options of "comfort cooling mode" and "conventional cooling mode", the "comfort cooling mode" may be manually selected by the user through command input, or may be automatically switched by the air conditioner 100 through detection and judgment of relevant parameters, and there is no limitation here.

[0139] For example, after entering the comfort cooling mode, if it is determined that the current ambient temperature is less than or equal to the first set temperature threshold (i.e., Th≤Ts1), it means that the ambient temperature meets the user's needs, and if it is determined that the current ambient temperature is greater than the first set temperature threshold (i.e., Th>Ts1), it means that the ambient temperature has not yet met the user's needs. Then, in the case of Th>Ts1, compared with the case of Th≤Ts1, it is necessary to adjust the air guide component 4 to be closer to the direct blowing angle, or increase the speed of the wind wheel 22, or increase the speed of the wind wheel 22 while adjusting the air guide component 4 to be closer to the direct blowing angle, so that the ambient temperature meets the user's needs as soon as possible. At the same time, since in the case of Th>Ts1, taking measures such as adjusting the air guide component 4 to be closer to the direct blowing angle and / or increasing the speed of the wind wheel 22 will enhance the wind feeling, in the case of Th>Ts1, the spoiler component 3 is started to reduce the wind feeling, thereby improving the comfort of the air supply while meeting the temperature requirements as soon as possible. In the case of Th≤Ts1, compared with the case of Th>Ts1, the wind guide component 4 is relatively far away from the direct blowing angle and / or the rotation speed of the wind wheel 22 is lower, which has the effect of preventing direct blowing. Therefore, there is no need to start the spoiler component 3, thereby reducing energy consumption.

[0140] It is worth noting that in the embodiment of the second aspect of the present application, the specific setting scheme of the spoiler component 3 is not limited. For example, reference can be made to the description of the embodiment of the first aspect mentioned above, but it is not limited to the description of the embodiment of the first aspect mentioned above. For example, there are multiple spoilers 32 and they are arranged at intervals along the length direction X of the air outlet 11 of the air conditioner 100, and the thickness direction of the spoiler 32 is consistent with the length direction X of the air outlet 11, etc., which will not be elaborated here.

[0141] It is worth noting that in the embodiment of the second aspect of the present application, there is no limitation on the way to achieve "the wind guide component 4 is close to the straight blowing angle in the second wind guiding state relative to the first wind guiding state", and corresponding control can be performed according to the specific form of the wind guide component 4.

[0142] For example, in some embodiments, reference Figure 1-Figure 13When the air conditioner 100 is a horizontal air conditioner, the length direction of the air outlet 11 is the left-right direction, the width direction of the air outlet 11 is the up-down tilt direction, the air guide component 4 may include a first air guide assembly 5 and a second air guide assembly 6, the first air guide assembly 5 includes an air guide blade 51 arranged in the air duct 210, the air guide blade 51 is a plurality of air guide blades 51 and is arranged at intervals along the length direction X of the air outlet 11, the air guide blade 51 is rotatably arranged, and the rotation axis L1 of the air guide blade 51 is perpendicular to the length direction X of the air outlet 11, and the air guide blade 51 is located at a position Downstream of the spoiler 32, the second air guide assembly 6 includes a second air guide plate 62, which extends along the length direction X of the air outlet 11. The second air guide plate 62 is rotatable and the rotation axis L4 of the second air guide plate 62 is parallel to the length direction X of the air outlet 11. The second air guide plate 62 is located downstream of the air guide blade 51. When the air conditioner 100 is in the off state, the second air guide plate 62 closes the air outlet 11. When the air conditioner 100 is in the working state, the second air guide plate 62 rotates to the bottom of the air outlet 11.

[0143] Combination Fig.24 , exemplarily, Th≤Ts1, the wind guide component 4 is in the first wind guide state, the angle of the wind guide blade 51 is α1, and the angle of the second wind guide plate 62 is β1; Th>Ts1, the wind guide component 4 is in the second wind guide state, the angle of the wind guide blade 51 is α2, and the angle of the second wind guide plate 62 is β2. Among them, the "angle α of the wind guide blade 51" (for example Figure 7 and Fig. 9 The angle β of the second air guide plate 62 (e.g. Fig.11 ) means: when the air conditioner 100 is turned off, the second air guide plate 62 closes the air outlet 11, and the second air guide plate 62 is in the initial position at this time. The angle of the second air guide plate 62 at this time is defined as 0°. During the operation of the air conditioner 100, the second air guide plate 62 rotates relative to the initial position. Setting: α2<α1, β2>β1, that is, in the second air guiding state, the angle of the second air guide plate 62 rotating downward is increased relative to the first air guiding state, and the air guide blade 51 is adjusted to have a smaller angle with the cross section S of the air outlet 11, so that the air supply angle can be closer to the straight blowing angle.

[0144] It is worth noting that in the embodiment of the second aspect of the present application, the specific arrangement of the air guide component 4 is not limited to the above description. For example, the first air guide plate 61 may be added with reference to the description of the embodiment of the first aspect, which will not be elaborated here.

[0145] Combination Fig. 22In some embodiments, the control method further includes: comparing the current ambient temperature (Th) with a second set temperature threshold (Ts2), wherein the second set temperature threshold (Ts2) is greater than the first set temperature threshold (Ts1); determining that the current ambient temperature is greater than the first set temperature threshold and less than or equal to the second set temperature threshold (i.e., Ts1<Th≤Ts2), controlling the spoiler component 3 to present a first spoiler state; determining that the current ambient temperature is greater than the second set temperature threshold (i.e., Th>Ts2), controlling the spoiler component 3 to present a second spoiler state, wherein the amplitude and frequency of the spoiler plate 32 of the spoiler component 3 in the second spoiler state are both reduced relative to those in the first spoiler state.

[0146] Combination Fig.24 , for example, Ts1<Th≤Ts2, the spoiler 3 presents the first spoiler state, the amplitude of the spoiler 32 is A1, and the frequency of the spoiler 32 is f1; Th>Ts2, the spoiler 3 presents the second spoiler state, the amplitude of the spoiler 32 is A2, and the frequency of the spoiler 32 is f2. Setting: f2<f1, A2<A1, that is, when Th>Ts2, the ambient temperature is further away from the comfortable temperature than when Ts1<Th≤Ts2, then the amplitude and frequency of the spoiler 32 are reduced, so that the spoiler effect of the spoiler 3 is weakened, the wind feeling is enhanced, and the temperature of the desired position can be adjusted more efficiently.

[0147] It is worth noting that the first speed interval includes at least one speed value, the second speed interval also includes at least one speed value, and the maximum speed value of the first speed interval is less than the minimum speed value of the second speed interval. For example, in some embodiments, the second speed interval can be further divided to include a first sub-interval and a second sub-interval, the second sub-interval is larger than the first sub-interval, wherein the first sub-interval includes at least one speed value, the second sub-interval also includes at least one speed value, and the maximum speed value of the first sub-interval is less than the minimum speed value of the second sub-interval. For example, the first speed interval has a first speed n1, the first sub-interval has a second speed n2, and the second sub-interval has a third speed n3, n3>n2>n1.

[0148] Combination Fig.23In some embodiments, the control method further includes: comparing the current ambient temperature (Th) with the second set temperature threshold (Ts2), wherein the second set temperature threshold (Ts2) is greater than the first set temperature threshold (Ts1); determining that the current ambient temperature is greater than the first set temperature threshold and less than or equal to the second set temperature threshold (i.e., Ts1<Th≤Ts2), and controlling the rotation speed of the wind wheel 22 to be in the first sub-interval; determining that the current ambient temperature is greater than the second set temperature threshold (i.e., Th>Ts2), and controlling the rotation speed of the wind wheel 22 to be in the second sub-interval. Thus, when Th>Ts2, relative to the case of Ts1<Th≤Ts2, increasing the rotation speed of the wind wheel 22 can increase the air volume to meet the user's demand for cooling temperature as soon as possible.

[0149] Combination Fig.24 For example, Th≤Ts1, the wind wheel 22 is controlled to run at the first speed n1; Ts1<Th≤Ts2, the wind wheel 22 is controlled to run at the second speed n2; Th>Ts2, the wind wheel 22 is controlled to run at the third speed n3. Since n3>n2>n1, the higher the indoor temperature is above the comfort temperature, the higher the speed of the wind wheel 22 can be adjusted, thereby increasing the air volume and improving the temperature regulation efficiency, so as to meet the user's demand for cooling temperature as soon as possible.

[0150] Next, a control method of the air conditioner 100 according to a specific embodiment of the present application is described.

[0151] Combination Fig.24 , after the air conditioner 100 enters the comfort cooling mode, the current ambient temperature (Th) is obtained and compared with the first set temperature threshold (Ts1) and the second set temperature threshold (Ts2), and the second set temperature threshold (Ts2) is greater than the first set temperature threshold (Ts1). If Th≤Ts1, the anti-direct blowing mode is turned on, and the wind wheel 22 is controlled to run at the first speed n1, the angle of the guide blade 51 is α1, and the angle of the second wind guide plate 62 is β1. If Ts1<Th≤Ts2, the wind wheel 22 is controlled to run at the second speed n2, the angle of the guide blade 51 is α2, and the angle of the second wind guide plate 62 is β2, n2>n1, α2<α1, β2>β1, and the spoiler component 3 is turned on at the same time, and the piezoelectric actuator drives the spoiler 32 to run at the frequency f1 and the amplitude A1. If Th>Ts2, the wind wheel 22 is controlled to run at the third speed n3, n3>n2, the angle of the guide blade 51 is still α2, the angle of the second wind guide plate 62 is still β2, and the spoiler component 3 is turned on at the same time, and the piezoelectric actuator drives the spoiler 32 to run at a frequency f2 and an amplitude A2, f2<f1, A2<A1.

[0152] Therefore, when the air conditioner 100 enters the comfort cooling mode, different control strategies can be set for the wind wheel 22, the spoiler component 3 and the wind guide component 4 according to the comparison between the current ambient temperature and the set comfort temperature (i.e., the second set temperature threshold and the first set temperature threshold), so as to ensure the wind feeling experience while meeting the ambient temperature regulation.

[0153] It is worth noting that the specific values ​​of the above parameters are not limited and can be set according to actual requirements. For example, the first set temperature threshold is 25°C-26°C, the second set temperature threshold is 28°C-29°C, etc., which will not be elaborated here.
