[0068] This invention proposes an indoor air conditioning unit 100, including a casing 20, a main heat exchanger 23, a vortex generator 10, and an auxiliary heat exchanger 121. In one embodiment of this invention, please refer to... Figures 1 to 3 The outer casing 20 has a main air inlet 21, a main air outlet 22, and a main air duct connecting the main air inlet 21 and the main air outlet 22; the main heat exchanger 23 is disposed in the main air duct; the vortex ring generator 10 is disposed in the outer casing 20, the vortex ring generator 10 has an auxiliary air duct and a convolution port 111 communicating with the auxiliary air duct, the convolution port 111 is used to allow indoor air to enter the auxiliary air duct, and the vortex ring generator 10 can generate vortex ring airflow blown out by the convolution port 111; the auxiliary heat exchanger 121 is disposed in the auxiliary air duct, the auxiliary air duct is isolated from the main air duct, wherein the temperature of the auxiliary heat exchanger 121 is adjustable.

[0069] Current air conditioning products use constant temperature control to regulate temperature, and their technology aims to create a stable, uniform, and constant indoor thermal environment, maintaining a consistent room temperature. However, within the same room, differences in age, gender, body type, and physiological parameters among occupants lead to varying heat needs. Maintaining a uniform room temperature results in some people feeling too cold and others too hot. Furthermore, current air conditioning technology primarily uses jet-flow technology, where airflow quickly diffuses after exiting the outlet, involving momentum and energy exchange. This prevents long-distance, targeted air delivery, especially in small rooms (e.g., with only one person). In such cases, current air conditioners need to regulate the temperature of a large space to meet the cooling / heating needs of that single individual, resulting in significant energy waste.

[0070] In this embodiment, it is understood that the outer casing 20 of the outdoor unit of the air conditioner is provided with a main air inlet 21 and a main air outlet 22. The main air duct connects the main air inlet 21 and the main air outlet 22. Under the action of the main system fan, outdoor air enters the main air duct through the main air inlet 21, undergoes heat exchange through the main heat exchanger 23 in the main air duct, and is then blown out through the main air outlet 22. The vortex generator 10 can be detachably installed inside or outside the casing 20, or it can be integrally formed with the casing 20. Furthermore, the vortex generator 10 is not limited to the cabinet-type indoor unit 100, but can also be other types of indoor units 100, such as wall-mounted indoor units 100. The shape of the convolution port 111 can be circular, rectangular, elliptical, etc., and can be selected according to the usage requirements, without specific limitations here. The temperature of the auxiliary heat exchanger 121 can be adjusted by controlling the refrigerant flow rate of the auxiliary heat exchanger 121, or by changing the heat exchange area of ​​the auxiliary heat exchanger 121 or by other adjustment methods.

[0071] Because the auxiliary air duct and the main air duct are isolated, the main system and the vortex ring module can operate independently or simultaneously. When the main system is running, indoor air enters the main air duct through the main air inlet 21, is cooled / heated by the main heat exchanger 23, and is then blown out through the main air outlet 22. The air outlet 22 uses jet technology to achieve uniform room temperature. When the vortex ring module is running, indoor air is drawn into the vortex ring generator 10 through the convolution port 111, is cooled / heated by the auxiliary heat exchanger 121 inside, and is then blown out through the convolution port 111 in the form of vortex ring air. The auxiliary air duct delivers air through vortex ring pulses, which can encapsulate the cold / heat in the volume of the airflow during the vortex ring flow characteristic process, delivering the cold / heat to the target area with less energy dissipation, thereby achieving temperature regulation of the local area.

[0072] When there are two or more users in the room, taking the heat exchange mode of the indoor unit 100 as the cooling mode as an example, the heat demand temperature of all users is T1 to T2. n T i For T1 to T n The lowest temperature in, T m For T1 to T n The highest temperature in the system can be set to T, which is the outlet air temperature of the vortex module. i The main system's outlet air temperature is set to T. m After stabilization, the temperature in most areas of the room is T. m The target air supply area temperature of the vortex ring module is T. i The temperature near the target air supply area is between T i With T m In this way, the thermal comfort needs of different users can be met simultaneously. Specifically, for example, if there are four users in a room with thermal temperature requirements of 25℃, 26℃, 27℃, and 28℃ respectively, the outlet air temperature of the vortex ring module can be set to 25℃, and the outlet air temperature of the main system can be set to 28℃. After stabilization, the temperature in most areas of the room will be 28℃, and the target air supply area temperature of the vortex ring module will be 25℃. Users with a thermal temperature requirement of 26℃ can move closer to the target air supply area, while users with a thermal temperature requirement of 27℃ can move further away from the target air supply area. In other embodiments, the target air supply area temperature of the vortex ring module is T. i The main system's outlet air temperature can also be set from T1 to T. n Except for T i The average temperature of the remaining areas T x When the indoor unit 100 of the air conditioner is in heating mode, the outlet air temperature of the vortex module can be set to T. m The main system's outlet air temperature is set to T. i In other words, the vortex ring module plays a role in locally enhancing cooling / heating.

[0073] When there is only one user in the room, the main system can be shut down, and only the vortex ring module can be operated. The outlet air temperature of the vortex ring module can be set to the user's thermal demand temperature. Because the energy dissipation of the vortex ring pulse air delivery process is low, it can achieve long-distance local air delivery. In this way, it is no longer necessary to rely on the main system to lower / raise the temperature of the entire room. Only the temperature of the local area needs to be adjusted by the vortex ring module to meet the user's thermal comfort needs, thereby greatly reducing air conditioning energy consumption. Of course, in other embodiments, the main air duct can also be in the open state, and its outlet air temperature can be set to the same temperature value as the outlet air temperature of the vortex ring module. To reduce air conditioning energy consumption, the airflow of the main air duct can be set to the minimum level.

[0074] In one embodiment of the present invention, please refer to Figure 6 and Figure 7 The vortex ring generator 10 includes a collector 11, a duct 12, a pusher plate 13, and a drive device 14. The collector 11 is connected to the duct 12, the convolution port 111 is opened in the collector 11, the auxiliary heat exchanger 121 and the pusher plate 13 are located inside the duct 12, and the auxiliary heat exchanger 121 is located between the collector 11 and the pusher plate 13. The drive device 14 is connected to the pusher plate 13 to drive the pusher plate 13 to reciprocate in the axial direction of the duct 12.

[0075] In this embodiment, the current collector 11 can be a structure with two openings, one large and one small, arranged opposite each other, such as a frustum or truncated cone structure, with the smaller opening being the convolution port 111. Alternatively, it can be a baffle structure with an opening, which is the convolution port 111. The air duct 12 is cylindrical in shape, and its cross-section can be rectangular, circular, elliptical, polygonal, or irregular, etc., and can be selected according to usage requirements, without specific limitations. The current collector 11 and the air duct 12 can be integrally formed or separately formed. It is understood that when the current collector 11 and the air duct 12 are separately formed, the current collector 11 and the air duct 12 are sealed together. The shape and size of the push plate 13 are matched with the cross-sectional shape and size of the air duct 12, so that the periphery of the push plate 13 abuts against the inner wall of the air duct 12. The push plate 13 can be a flat plate or a curved plate. The vortex generator 10 also includes a back plate 15, which is connected to a short section of the air duct 12 away from the collector 11. The back plate 15 has openings to balance the indoor air pressure and the air pressure between the push plate 13 and the back plate 15 in the air duct 12, so as to avoid the resistance of pushing the push plate 13 due to the increase of pressure difference.

[0076] The drive unit 14 can drive the pusher plate 13 to reciprocate axially in the air duct 12. When the pusher plate 13 moves away from the collector 11, the air pressure between the pusher plate 13 and the collector 11 decreases, and indoor air is drawn into the air duct 12 through the convolution port 111. When the pusher plate 13 moves closer to the collector 11, the air pressure between the pusher plate 13 and the collector 11 increases, and the airflow is blown out through the collector 11. Since the air passage area of ​​the convolution port 111 is smaller than that of the air passage area of ​​the air duct 12, part of the airflow flowing from the air duct 12 to the convolution port 111 will flow along the inner wall of the collector 11 and then out from the periphery of the convolution port 111, while another part of the airflow will flow out from the middle of the convolution port 111. The part of the airflow flowing out from the edge of the convolution port 111 is defined as the edge airflow, and the airflow flowing out from the middle of the convolution port 111 is defined as the middle airflow. Therefore, the edge airflow is subject to the resistance of the inner wall of the collector 11. Compared to the airflow in the middle, the velocity is lower. This velocity difference causes the airflow to generate a vortex ring airflow with a certain speed when it flows out of the convolution port 111. Since the drive device 14 continuously drives the pusher plate 13 to move back and forth inside the air duct 12, it continuously provides momentum and mass to the vortex ring airflow, thereby achieving long-distance air delivery. Moreover, when the airflow flows through the auxiliary heat exchanger 121 inside the air duct 12, heat exchange occurs, causing the vortex ring airflow to be cooled / heated before being sent out from the convolution port 111, thus achieving temperature regulation.

[0077] In one embodiment of the present invention, please refer to Figure 6 The air duct 12 includes a first section 12a and a second section 12b. The auxiliary heat exchanger 121 is disposed in the first section 12a, and the pusher plate 13 can reciprocate within the second section 12b. In this embodiment, it can be understood that the first section 12a and the second section 12b can be integrally formed or separately formed. When the first section 12a and the second section 12b are separately formed, they are sealed together, which facilitates the assembly of the vortex ring generator 10.

[0078] In one embodiment of the present invention, please refer to Figure 7 and Figure 8 The driving device 14 is disposed outside the wall of the air duct 12. In this embodiment, the convolution port 111 faces the front panel of the air conditioner indoor unit 100, and the axial direction of the air duct 12 is the thickness direction of the air conditioner indoor unit 100. The driving device 14 is disposed outside the wall of the air duct 12, which can avoid occupying the space in the thickness direction of the air conditioner indoor unit 100, thereby reducing the thickness of the air conditioner indoor unit 100.

[0079] In one embodiment of the present invention, please participate Figure 7 and Figure 8The driving device 14 includes a motor 141 and a transmission component. One end of the transmission component is connected to the motor 141, and the other end is connected to the push plate 13. The motor 141 drives the transmission component to rotate, thereby causing the push plate 13 to reciprocate along the axial direction of the air duct 12. Rotational motion occupies less space than linear motion. By using a rotational transmission component to drive the push plate 13 in linear motion, the space occupied by the driving device 14 can be effectively reduced.

[0080] Specifically, the pusher plate 13 has a crossbeam 132 on the side opposite to the collector 11, and the crossbeam 132 has a sliding groove 133. The transmission component includes a crank 142, which includes a central rotating shaft 142a and an eccentric rotating shaft 142b. The central rotating shaft 142a is connected to the motor 141, and the eccentric rotating shaft 142b extends into the sliding groove 133. When the motor 141 drives the transmission component to rotate, the eccentric rotating shaft 142b slides in the sliding groove 133 and drives the pusher plate 13 to reciprocate axially in the air duct 12.

[0081] In this embodiment, please refer to Figure 7 The central rotating shaft 142a and the eccentric rotating shaft 142b are connected by a disk 142c. The surface of the disk 142c is parallel to the tangential surface of the wall of the air duct 12. The axes of both the central rotating shaft 142a and the eccentric rotating shaft 142b are perpendicular to the surface of the disk 142c. The central rotating shaft 142a is connected to the center of the disk 142c, and the eccentric rotating shaft 142b is connected to other positions on the disk 142c except for the center, such as the outer periphery of the disk 142c. When the axial distance between shaft 142a and eccentric shaft 142b is the same, connecting eccentric shaft 142b to the outer circumference of disk 142c minimizes the diameter of disk 142c compared to connecting it to other positions on disk 142c, thereby reducing the space occupied by crank 142. When motor 141 drives transmission components to rotate, central shaft 142a rotates around its axis, while eccentric shaft 142b rotates around central shaft 142a via disk 142c. It is understood that in other embodiments, the central rotating shaft 142a and the eccentric rotating shaft 142b can also be connected by a connecting rod, with the two ends of the connecting rod connected to the central rotating shaft 142a and the eccentric rotating shaft 142b respectively, and the connecting rod forming an angle with the central rotating shaft 142a, which can be 90 degrees, 70 degrees or 120 degrees, etc. When the motor 141 drives the transmission component to rotate, the central rotating shaft 142a rotates around its axis, and the eccentric rotating shaft 142b rotates around the central rotating shaft 142a through the connecting rod.

[0082] In this embodiment, please refer to Figure 4 and Figure 7The push plate 13 is a flat plate, and the crossbeam 132 is arranged radially along the push plate 13. The slide groove 133 is perpendicular to the axis of the eccentric rotating shaft 142b. The eccentric rotating shaft 142b is fixed in the slide groove 133 in its axial direction by a bearing 134, and can slide in the slide groove 133 in its radial direction. When the motor 141 drives the transmission component to rotate, the rotational motion of the eccentric rotating shaft 142b is converted into sliding in the radial direction of the air duct 12, and the push plate 13 is driven to reciprocate in the axial direction of the air duct 12 by the crossbeam 132. It can be understood that in other embodiments, the push plate 13 can also be a curved plate, and the two ends of the crossbeam 132 are connected to the push plate 13. The transmission component can also be a gear and rack structure. The gear is set on the drive shaft of the motor 141. The push plate 13 can also include a peripheral wall extending from its periphery along the inner wall of the air duct 12 in a direction away from the collector 11. The rack is set on its peripheral wall. When the motor 141 drives the gear to rotate, the push plate 13 is driven to move back and forth through the meshing of the gear and the rack.

[0083] In one embodiment of the present invention, please refer to Figure 7 and Figure 8 At least one guide rail 122 is provided on the wall of the air duct 12. The guide rail 122 is arranged radially along the air duct 12. At least one roller 131 is provided around the periphery of the push plate 13 to cooperate with the guide rail 122. Specifically, the guide rail 122 is provided on the inner side of the wall of the air duct 12. There may be only one guide rail 122, or there may be two or more guide rails, which are evenly distributed on the inner side of the wall of the air duct 12. For example, with the drive device 14 at the bottom, three guide rails 122 are provided, located at the top, left and right respectively. One or more rollers 131 are provided around the periphery of the push plate 13 to cooperate with each guide rail 122. Each guide rail 122 is equipped with one roller 131. When the push plate 13 moves back and forth in the axial direction of the air duct 12, the rollers 131 roll along the guide rail 122 to limit the rotation of the push plate 13 during the movement, and at the same time reduce the frictional resistance encountered by the push plate 13 when it moves. The outer wall of roller 131 is made of rubber, which can reduce the noise generated by roller 131 running within guide rail 122. In other embodiments, roller 131 can also be replaced with slider.

[0084] In one embodiment of the present invention, the fins of the auxiliary heat exchanger 121 are arranged in a honeycomb pattern.
