[0036] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0037] The air outlet assembly proposed in the embodiment of the present invention includes an air outlet frame or an air guide plate, which is arranged at the air outlet of the air conditioner. For example, the air outlet frame can constitute the side wall of the air outlet of an air treatment device such as an air conditioner. For example, the air guide plate can be rotatably arranged at the air outlet of an air treatment device such as an air conditioner. The air outlet assembly also includes at least one electromagnetic resonant air guide structure 100, such as Figures 1 to 4 As shown, each electromagnetic resonant wind-guiding structure 100 includes: a base 110, the base 110 is arranged on the air outlet frame or the air guide plate, and the base 110 and the air outlet frame or the air guide plate can be directly or indirectly connected or integrally formed; a resonant actuator, the resonant actuator includes an electromagnetic coil component 120 and a magnetic component 130, the electromagnetic coil component 120 is arranged on the base 110; and an air guide blade 200, the air guide blade 200 is arranged on the base 110 and forms a cantilever structure 210, the magnetic component 130 is arranged on the air guide blade 200 and is spaced relative to the electromagnetic coil component 120; wherein, the electromagnetic coil component 120 is arranged to drive the magnetic component 130 to move, thereby driving the air guide blade 200 to resonate to achieve turbulence.

[0038] In the air outlet assembly, the electromagnetic coil component 120 is loaded with alternating current that is adapted to the natural frequency of the air guide blade 200. Alternating repulsive and attractive forces are generated between the electromagnetic coil component 120 and the magnetic component 130, causing the air guide blade 200 to resonate and enabling the cantilever structure 210 to swing to a greater extent. The electromagnetic resonance wind guide device is applied to the indoor unit of the air conditioner as an air guide structure, and its effect on the air volume of the indoor unit of the air conditioner is very small; in addition, the magnetic part 130 resonates with the air guide blade 200, and the cantilever structure 210 swings to a large extent, which will increase the blowing range of the air flow blown out of the air outlet of the indoor unit of the air conditioner, and can improve the wind feeling and blowing comfort of the air outlet, the air circulation flow speed of the room and the heat exchange uniformity of the room; furthermore, the air guide blade 200 has multiple natural frequencies. By changing the frequency of the alternating current loaded on the electromagnetic coil component 120 to switch the air guide blade 200 to resonate at different frequencies, the wind feeling of the air outlet can be changed, and air supply with different wind feelings can be achieved; and / or by changing the voltage of the alternating current loaded on the electromagnetic coil component 120 to change the amplitude of the cantilever structure 210, the wind feeling of the air outlet can also be changed, and air supply with different wind feelings can be achieved.

[0039] like Figure 8 As shown, when the air outlet does not utilize the wind guide blades and does not resonate and turbulently blow, the air blows straight out, which can easily cause discomfort to the user. Figure 9 As shown, the electromagnetically driven air guide blades 200 in the air outlet assembly resonate and turbulently cause the air outlet speed, wind direction and turbulence intensity to vary greatly, making the air outlet softer and more varied, and the air outlet range wider, which can bring a comfortable wind feeling and a good cooling effect.

[0040] 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 an oscillating system is subjected to a periodic external force, when the frequency of the external force is the same as or very close to the natural oscillation frequency of the system, the amplitude increases sharply. The frequency at which resonance occurs is called the "resonant frequency". In addition, the "natural frequency" is also called the "natural frequency". When an object vibrates freely, its displacement changes with time according to the sine or cosine law. The frequency of vibration is independent of the initial conditions and 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 that occurs in a mechanical system after the excitation or constraint is removed. The vibration is maintained only by its elastic restoring force. When there is damping, the vibration gradually decays. The frequency of free vibration is determined only by the physical properties of the system itself, which is called the natural frequency of the system.

[0041] Simply put, when the excitation frequency of the resonant actuator is the same as or close to the natural frequency of the air guide blade 200, the resonance effect is utilized, and the vibration generated by the air guide blade 200 is called resonance (such as the natural frequency of the air guide blade 200 includes multiple-order natural frequencies such as the first-order natural frequency, the second-order natural frequency, and the third-order natural frequency, then the corresponding resonance generated by the air guide blade 200 includes the first-order resonance, the second-order resonance, and the third-order resonance). The amplitude of the air guide blade 200 will increase sharply, so that the air guide blade 200 can more effectively disturb the flow, improve the wind field distribution of the airflow at the air outlet, and achieve the effect of improving the wind feel of the airflow blown from the air outlet and the user's blowing comfort.

[0042] In some embodiments, the resonant frequency of the air guide blades 200 and the magnetic member 130 is set to be within the range of 1 Hz-100 Hz. The corresponding frequency of the alternating current applied to the electromagnetic coil member 120 is within the range of 1 Hz-100 Hz. The electromagnetic coil member 120 drives the air guide blades 200 and the magnetic member 130 to resonate within the range of 1 Hz-100 Hz. This can increase the range of the airflow from the air outlet, thereby improving the airflow feel and comfort, the air circulation speed in the room, and the uniformity of heat exchange in the room.

[0043] The electromagnetic coil component 120 can be loaded with alternating current in the range of 1Hz-100Hz (for example, 1Hz, 10Hz, 20Hz, 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, etc.) as needed to drive the natural frequency of the wind guide blade 200 that matches it to resonate, thereby meeting different requirements for the wind feel of the air outlet. Furthermore, the electromagnetic coil component 120 can be loaded with alternating current in the range of 5Hz-60Hz (for example, 10Hz, 20Hz, 30Hz, 40Hz, 50Hz, 60Hz, etc.) to drive the natural frequency of the wind guide blade 200 that matches it to resonate, thereby meeting different requirements for the wind feel of the air outlet. Of course, the present invention is not limited to this. In other embodiments, the electromagnetic coil component 120 can also be loaded with alternating current greater than 100Hz as needed, which will not be elaborated here.

[0044] The electromagnetic coil component 120 is loaded with alternating current that is adapted to the natural frequency of the air guide blade 200. The electromagnetic coil component 120 drives the magnetic part 130 to vibrate at a frequency that is adapted to the natural frequency of the air guide blade 200 through magnetic pole conversion. The vibration frequency of the magnetic part 130 is adapted to the natural frequency of the air guide blade 200. The magnetic part 130 resonates with the air guide blade 200, thereby enabling the cantilever structure 210 to swing at a relatively large amplitude.

[0045] The drive motors used in general air conditioner indoor units 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 movement. 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, from a technical point of view, 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 guides, swing blades, and connecting rod mechanisms. Stepper motors can drive components to reciprocate, but the driving frequency is very low compared to the resonant frequency. 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, the brushless DC motor and stepper motor used in general air conditioners cannot drive the air guide blades 200 to resonate within the range of 1Hz-100Hz, so that the air guide blades 200 cannot effectively disturb the air flow to improve the wind feel of the air flow blown out of the air outlet.

[0046] In some exemplary embodiments, Figures 1 to 4 As shown, in each electromagnetic resonant wind guide structure, the wind guide blades 200 and the magnetic members 130 each include two groups. The two groups of magnetic members 130 are installed in a one-to-one correspondence with the two groups of wind guide blades 200. The electromagnetic coil component 120 is located between the two groups of wind guide blades 200. The two magnetic poles of the electromagnetic coil component 120 correspond one-to-one with the two groups of magnetic members 130. That is, the two groups of magnetic members 130 are respectively arranged outside the two magnetic poles of the electromagnetic coil component 120 and spaced apart from the electromagnetic coil component 120. Through a single electromagnetic coil component 120, the combined structure of the two groups of magnetic members 130 and the wind guide blades 200 can be driven to resonate simultaneously, reducing the number of electromagnetic coil components 120 used by half. Not only is the structure simpler, but the wind resistance generated by the electromagnetic resonant wind guide device in the air outlet can also be better reduced.

[0047] In some examples, such as Figures 2 to 4 As shown, each cantilever structure 210 is provided with a magnet at its base. For example, two magnets are provided on either side of the base of each cantilever structure 210, and each magnetic member 130 includes two magnets. The magnets are provided at the base of the cantilever structures 210, thereby enhancing the cantilever structures 210's ability to disrupt the airflow within the air outlet. Furthermore, the magnets have a smaller swing stroke, which reduces the wind resistance generated by the magnets within the air outlet.

[0048] Of course, it is also possible that only one magnet is provided at the root of each group of cantilever structures 210, and each group of magnetic parts 130 includes a magnet, and the magnet is provided on the side of the root of the cantilever structure 210 close to the electromagnetic coil component 120, which can also achieve the purpose of this application. Its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should also fall within the scope of protection of this application.

[0049] In some examples, the magnetic poles of the two sets of magnetic members near the electromagnetic coil are the same, both being S poles or both being N poles. For example, the right end of the magnetic member on the left side of the electromagnetic coil member 120, i.e., the end near the electromagnetic coil member 120, is S pole, and the left end of the magnetic member on the right side of the electromagnetic coil member 120, i.e., the end near the electromagnetic coil member 120, is also S pole. When AC power is applied to the electromagnetic coil member 120, at the first moment, the left end of the electromagnetic coil member 120 forms an S pole and the right end forms an N pole. The magnetic member on the left side of the electromagnetic coil member 120 experiences a repulsive force, causing the left wind guide vane 200 to swing leftward, while the magnetic member on the right side of the electromagnetic coil member 120 experiences an attractive force, similarly causing the right wind guide vane 200 to swing leftward. Similarly, at the second moment, the left end of the electromagnetic coil member 120 forms an N pole and the right end forms an S pole. The magnetic member on the left side of the electromagnetic coil member 120 experiences an attractive force, causing the left wind guide vane 200 to swing rightward, while the magnetic member on the right side of the electromagnetic coil member 120 experiences an attractive force, similarly causing the right wind guide vane 200 to swing rightward. The identical magnetic poles of the two sets of magnetic components near the electromagnetic coil enable the two sets of wind guide blades in the same electromagnetic resonant wind guide structure to swing in the same direction, facilitating control of the overall wind feel of the outlet air. For example, different forms of wind feel, such as pulsating wind, can be achieved. In other examples, the magnetic poles of the two sets of magnetic components near the electromagnetic coil are opposite, with one being the south pole and the other being the north pole. When the electromagnetic coil assembly 120 is connected to alternating current, the electromagnetic coil assembly 120 simultaneously attracts or repels the two sets of magnetic components, causing the two sets of wind guide blades 200 to swing in opposite directions, thereby increasing the turbulence of the outlet air and balancing the force on the base 110.

[0050] It can be, for example Figures 1 to 4 As shown, the axes of the two groups of cantilever structures 210 are relatively parallel (i.e., the angle between the axes of the two groups of cantilever structures 210 is 0 degrees), and the axes of the cantilever structures 210 can be the line between the end of the cantilever structure 210 connected to the base 110 and its free end; or, the axes of the two groups of cantilever structures 210 are relatively tilted (i.e., the angle between the two groups of cantilever structures 210 is between 0 degrees and 180 degrees). The relative tilt of the axes of the two groups of cantilever structures 210 can mean that the axes of the two groups of cantilever structures 210 are respectively located on planes perpendicular to the electromagnetic coil component 120 at both ends of the electromagnetic coil component 120 and the axes of the two groups of cantilever structures 210 are not parallel and form an angle, for example, one group of cantilever structures 210 extends along the air outlet direction, and the other group of cantilever structures 210 extends perpendicular to the air outlet direction or extends in the opposite direction of the air outlet direction; the above can all achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the scope of protection of the present application.

[0051] In some exemplary embodiments, Figures 2 to 4As shown, the base 110 includes two groups of first bases, which are spaced apart. Two groups of wind guide blades 200 are mounted on the two groups of first bases in a one-to-one correspondence. The electromagnetic coil component 120 is mounted on at least one of the two groups of first bases.

[0052] It can be, for example Figure 1 and Figure 2 As shown, the end faces (such as the upper end faces) of the two groups of first bases are protrudingly provided with mounting platforms 111, and the same ends of the two groups of wind guide blades 200 are installed one-to-one on the opposite sides of the two groups of first bases (such as installed on the left side of the base 110 located on the left and installed on the right side of the base 110 located on the right), the two groups of mounting platforms 111 are located between the two groups of cantilever structures 210, and the electromagnetic coil component 120 is located between the two groups of mounting platforms 111, and the two ends (such as the left end and the right end) of the electromagnetic coil component 120 are installed one-to-one on the two groups of mounting platforms 111, which facilitates the assembly and installation of the electromagnetic resonant wind guide structure.

[0053] In some embodiments, as Figure 1 and Figure 2 As shown, the electromagnetic coil component 120 includes an iron core and a coil. The two ends of the iron core are mounted on two sets of mounting platforms 111 in a one-to-one correspondence. The coil is located between the two sets of mounting platforms 111 and wound outside the iron core. Alternating current is loaded on the coil.

[0054] It is possible that the diameter of the coil is set to 0.1mm-5mm. For example, if the diameter of the coil is set to 0.1mm, 1mm, 2mm or 5mm, etc., the purpose of this application can be achieved. Its purpose does not deviate from the design concept of the present invention and will not be repeated here. It should all fall within the scope of protection of this application.

[0055] In other exemplary embodiments, each electromagnetic resonant wind-guiding structure includes an integral base, two sets of wind-guiding blades are mounted at both ends of the base, and the electromagnetic coil component is mounted in the middle of the base, where the middle of the base refers to any position between the two ends of the base. In other exemplary embodiments, each electromagnetic resonant wind-guiding structure includes two sets of second bases and a third base disposed between the two sets of second bases, the two sets of wind-guiding blades are mounted one-to-one on the two sets of second bases, and the electromagnetic coil component is mounted on the third base, i.e., the two sets of wind-guiding blades and the electromagnetic coil component are disposed on separate bases.

[0056] In some embodiments, the electromagnetic coil component 120 is configured to load alternating current with a frequency in the range of 1 Hz-100 Hz, and the frequency of the loaded alternating current is adapted to the natural frequency of the wind guide blade 200 to achieve resonance between the magnet and the wind guide blade 200 .

[0057] In some exemplary embodiments, Figure 3 and Figure 4As shown, the air outlet assembly also includes: a mounting base 300, and the electromagnetic resonance air guide structure 100 includes multiple electromagnetic resonance air guide structures 100, and the multiple electromagnetic resonance air guide structures 100 are installed on the mounting base 300 at intervals through the base 110, and the mounting base 300 is fixed on the air outlet frame or air guide plate of the air conditioner indoor unit.

[0058] It can be that multiple electromagnetic resonant wind guide structures 100 are arranged in a row; or it can be that multiple electromagnetic resonant wind guide structures 100 are arranged in multiple rows, etc.; the above can all achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the scope of protection of this application.

[0059] The air conditioner indoor unit provided in the embodiment of the present invention is as follows: Figures 5 to 7 As shown, the air outlet assembly includes a body 400 and any of the above embodiments, and the air outlet assembly is installed at the air outlet of the body 400. A fan, such as a cross-flow fan, is installed in the body 400 to make air flow and discharge from the air outlet. The electromagnetic resonant air guide structure 100 on the air outlet assembly turbulents the air blown by the fan.

[0060] The indoor unit of the air conditioner has all the advantages of the air outlet assembly proposed in any of the above embodiments, which will not be described in detail here.

[0061] It can be, for example Figure 5 As shown, a plurality of electromagnetic resonant wind guide structures 100 form a row; or may be, as shown in FIG. Figure 6 and Figure 7 As shown, multiple electromagnetic resonant wind guide structures 100 are arranged in multiple rows; the above can all achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the scope of protection of this application.

[0062] It can be, for example Figure 6 As shown, multiple electromagnetic resonance air guide structures 100 are arranged in multiple rows spaced apart from each other in the width direction of the air outlet, i.e., the air outlet direction, and each row is configured to act synchronously or independently. In this way, the turbulence effects of the multiple electromagnetic resonance air guide structures 100 in the air outlet direction are superimposed on each other, and the air supply effects at each position in the length direction of the air outlet can be the same; or it can be, for example Figure 7 As shown, multiple electromagnetic resonant air-guiding structures 100 are arranged into multiple rows spaced apart from each other in the length direction of the air outlet (perpendicular to the air outlet direction), spaced apart from each other in the length direction of the air outlet, and configured to move independently of each other, so that zoned air supply can be achieved in the length direction of the air outlet; the above can all achieve the purpose of this application, and its purpose does not deviate from the design idea of the present invention, and will not be repeated here, and should all fall within the protection scope of this application.

[0063] An air conditioner (not shown in the figures) provided in an embodiment of the present invention includes the air conditioner indoor unit described in any one of the above embodiments.

[0064] This air conditioner has all the advantages of the indoor air conditioner provided by any of the above embodiments, which will not be described in detail here.

[0065] In summary, the air outlet assembly proposed in the embodiment of the present invention is loaded with an alternating current (AC) corresponding to the natural frequency of the air guide blades by the electromagnetic coil component, causing the air guide blades to resonate and achieving a relatively large swing of the cantilever structure. The electromagnetic resonant air guide structure 100 is applied to the indoor unit of the air conditioner as an air guide structure, and its effect on the air volume of the indoor unit of the air conditioner is minimal. In addition, the magnetic component resonates with the air guide blades, causing the cantilever structure to swing relatively large, which increases the blowing range of the airflow blown out of the air outlet, thereby improving the air outlet feel and blowing comfort, the air circulation speed in the room, and the heat exchange uniformity of the room. Furthermore, the air guide blades have multiple natural frequencies.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0071] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.

[0072] In any one or more of the above exemplary embodiments, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored as one or more instructions or codes on or transmitted via a computer-readable medium and executed by a hardware-based processing unit. The computer-readable medium may include a computer-readable storage medium corresponding to a tangible medium such as a data storage medium, or a communication medium that facilitates the transfer of a computer program from one place to another, such as according to a communication protocol. In this manner, a computer-readable medium may generally correspond to a non-transitory tangible computer-readable storage medium or a communication medium such as a signal or carrier wave. The data storage medium may be any available medium that can be accessed by one or more computers or one or more processors to retrieve instructions, codes, and / or data structures for implementing the techniques described in this disclosure. A computer program product may include a computer-readable medium.

[0073] By way of example and not limitation, such computer-readable storage media may include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage, flash memory, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer. Furthermore, any connection may also be referred to as a computer-readable medium. For example, if instructions are transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwaves, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwaves are included in the definition of medium. However, it should be understood that computer-readable storage media and data storage media do not include connections, carrier waves, signals, or other transient (transient) media, but rather refer to non-transient tangible storage media. As used herein, disk and optical disk include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, or Blu-ray disc, among others, where disks typically reproduce data magnetically, while optical discs use lasers to reproduce data optically. Combinations of the above should also be included within the scope of computer-readable media.

[0074] For example, instructions may be executed by one or more processors, such as one or more digital signal processors (DSPs), general-purpose microprocessors, application-specific integrated circuits (ASICs), field-programmable logic arrays (FPGAs), or other equivalent integrated or discrete logic circuits. Thus, the term "processor," as used herein, may refer to any of the aforementioned structures or any other structure suitable for implementing the techniques described herein. Additionally, in some aspects, the functionality described herein may be provided within dedicated hardware and / or software modules configured for encoding and decoding, or incorporated into a combined codec. Furthermore, the techniques may be fully implemented in one or more circuits or logic elements.

[0075] The technical solutions of the embodiments of the present disclosure can be implemented in a wide variety of devices or equipment, including wireless mobile phones, integrated circuits (ICs), or a group of ICs (e.g., chipsets). Various components, modules, or units are described in the embodiments of the present disclosure to emphasize the functional aspects of the devices configured to perform the described techniques, but they do not necessarily need to be implemented by different hardware units. Instead, as described above, the various units can be combined in a codec hardware unit or provided by a collection of interoperable hardware units (including one or more processors as described above) in combination with appropriate software and / or firmware.
