Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, for example to an air conditioning device and its vortex ring generator. Background Technology

[0002] Currently, when the supply air temperature of air conditioning equipment, such as air conditioners, is higher or lower than the indoor temperature, the supply airflow will be deflected upward or downward in a wide range due to the buoyancy effect caused by the temperature difference. This will disrupt the expected airflow organization and make it impossible to effectively deliver fresh air to the target area. For example, when an air conditioner delivers hot air, the supply hot airflow is deflected upward due to the buoyancy caused by the indoor temperature difference and cannot be delivered to the target area.

[0003] To solve the above problems, the following two solutions are often adopted: 1) Increase the air supply volume to mix the indoor air as much as possible and create an indoor environment with approximately uniform parameters; 2) Increase the air supply speed and use a high initial velocity jet to minimize the impact of buoyancy on the air supply airflow and deliver fresh air to the target area before the cold / hot air supply airflow deviates significantly.

[0004] The two solutions mentioned above have the following drawbacks: For solution 1), increasing the air volume will significantly increase energy consumption when the indoor occupancy rate is low; for solution 2), increasing the air supply speed will result in the air still having a large speed when it reaches the target area, resulting in a strong blowing sensation near the target location, which makes it difficult to meet the user's needs for air supply comfort. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides an air conditioning device and its vortex generator to solve the problem that the airflow cannot be delivered to the target area due to the deviation caused by temperature difference.

[0007] The first aspect of this application provides a vortex ring generator, comprising: a housing defining an airflow channel; a partition assembly located within the airflow channel and dividing the airflow channel into a working chamber and an air supply chamber arranged sequentially along the airflow direction; and a drive member disposed within the airflow channel and acting on the partition assembly to intermittently connect the working chamber and the air supply chamber.

[0008] The second aspect of this application provides an air conditioning device, including: an indoor unit, including a housing, and having a heat exchange air duct outlet; a vortex generator as described in any of the above technical solutions, disposed at the heat exchange air duct outlet, and the flow area of ​​the air outlet of the airflow channel is less than or equal to the flow area of ​​the heat exchange air duct outlet.

[0009] The air conditioning equipment and its vortex generator provided in this disclosure can achieve the following technical effects:

[0010] The airflow within the airflow channel flows sequentially through the working chamber and the air supply chamber. In other words, the air inlet of the airflow channel is connected to the working chamber, and the air outlet of the airflow channel is connected to the air supply chamber. A driving component is located within the airflow channel and acts on the partition assembly, causing intermittent communication between the working chamber and the air supply chamber. This results in intermittent airflow from the air supply outlet of the airflow channel, achieving vortex-ring air supply. Vortex-ring air supply enables low-speed, long-distance air delivery. While achieving long-distance delivery, it avoids discomfort caused by excessive air velocity and does not require increasing the air volume. Therefore, it can deliver airflow to the target area while increasing the energy consumption of the air conditioning equipment and meeting the requirements for air supply comfort.

[0011] The baffle assembly divides the airflow channel into a working chamber and an air supply chamber, and the working chamber and the air supply chamber are arranged sequentially along the airflow direction in the airflow channel. In this way, when the working chamber and the air supply chamber are not connected, outside air will not enter the working chamber through the air supply chamber, that is, it avoids outside air flowing back into the working chamber through the air supply chamber. In this way, this application can prevent the air vortex ring from being composed of backflowing air, thereby enabling the delivery of fresh air in the unit.

[0027] Unless otherwise stated, the term "multiple" means two or more.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0029] Combination Figure 1-4 and Figure 7 As shown, this embodiment of the disclosure provides a vortex ring generator 100, which is used in an air conditioning device 200. The air conditioning device 200 can be an air conditioner or a ducted air conditioner. The air conditioner can be, for example,... Figure 7 The wall-mounted air conditioner shown or such Figure 1 The cabinet-type air conditioner shown.

[0030] like Figures 2 to 4 As shown, the vortex ring generator 100 includes a housing 2, a partition assembly, and a drive component 3.

[0031] The housing 2 defines an airflow channel 23, and the airflow entering the airflow channel 23 from the air inlet of the airflow channel 23 flows out through the air outlet 232 of the airflow channel 23.

[0032] The baffle assembly is located within the airflow channel 23 and divides the airflow channel 23 into a working chamber 21 and an air supply chamber 22 arranged sequentially along the airflow direction, such as... Figure 2In the diagram, the area within the dashed box on the left is the working chamber 21, and the area within the dashed box on the right is the air supply chamber 22. In other words, the working chamber 21 is connected to the air inlet of the airflow channel 23, and the air supply chamber 22 is connected to the air outlet 232 of the airflow channel 23. The airflow entering through the air inlet of the airflow channel 23 enters the working chamber 21, flows into the air supply chamber 22, and then flows out from the air outlet 232 of the airflow channel 23.

[0033] The driving component 3 is located in the airflow channel 23 and acts on the partition assembly to intermittently connect the working chamber 21 and the air supply chamber 22. That is, the airflow entering the working chamber 21 from the air inlet of the airflow channel 23 intermittently flows into the air supply chamber 22, and the air outlet 232 of the airflow channel 23 intermittently discharges air. The airflow is sheared and rolled up at the air outlet 232 of the airflow channel 23 to generate an air vortex ring.

[0034] A vortex ring is a closed-loop ring structure. Vortex rings possess characteristics such as structural stability and low energy dissipation during motion. Therefore, utilizing air vortex rings to deliver fresh air can significantly reduce the influence of the environment on the delivered air, thereby overcoming the buoyancy effect caused by temperature differences. This allows for precise and efficient air delivery to target areas or locations, a process known as vortex ring air delivery. In other words, vortex ring air delivery enables long-distance, directional, and efficient air delivery, ensuring that the air reaches the target area.

[0035] The drive unit is located within the working chamber and is used to change the air pressure distribution within the working chamber to intermittently connect the working chamber and the air supply chamber.

[0036] The driving component is located within the working chamber and can move relative to it. During its movement, the driving component alters the air pressure distribution within the working chamber; that is, the air pressure increases in some areas and decreases in others. Where the pressure increases, the air pressure acts on the partition assembly, opening it and connecting the working chamber and the air supply chamber. Where the pressure decreases, the air pressure is too low to open the partition assembly, preventing the working chamber and the air supply chamber from connecting.

[0037] The baffle assembly divides the airflow channel 23 into a working chamber 21 and an air supply chamber 22 arranged sequentially along the airflow direction in the airflow channel 23. When the drive unit is in the initial position (e.g. Figure 3 and Figure 4When the driving component is currently in its initial position, the working chamber 21 and the air supply chamber 22 are not connected, and no vortex ring is generated; therefore, the vortex ring generator 100 does not supply air. Due to the separation effect of the baffle assembly, when the vortex ring generator 100 does not supply air, the working chamber 21 and the air supply chamber 22 are separated. The airflow that flows back into the air supply chamber 22 through the air supply port 232 of the airflow channel 23 will not enter the working chamber 21. Thus, when the driving component deviates from its initial position, the working chamber 21 and the air supply chamber 22 are connected, realizing vortex ring air supply. Since there is no airflow returning through the air supply port 232 of the airflow channel 23 in the working chamber 21, the vortex ring is composed of fresh air, not returning air. Therefore, the air conditioning device 200 in this application can achieve the delivery of fresh air. In other words, without the partition assembly, when the vortex generator 100 does not generate a vortex, ambient air will flow back into the airflow channel 23 through the air outlet 232. Thus, when the drive unit moves and the vortex generator 100 generates a vortex, the generated vortex includes ambient air that has flowed back into the airflow channel 23, making it difficult for the air conditioning equipment 200 to deliver fresh air.

[0038] Optionally, such as Figure 3 and Figure 4 As shown, the air inlet of the airflow channel 23 includes a first air inlet area 2311 and a second air inlet area 2312.

[0039] The drive component 3 is plate-shaped and is disposed in the working chamber 21, dividing the working chamber 21 into a first working chamber 211 that is connected to the first air inlet area 2311 and a second working chamber 212 that is connected to the second air inlet area 2312. That is, the first working chamber 211 and the second working chamber 212 are respectively connected to different air inlet areas on the air inlet of the airflow channel 23. Specifically, the airflow entering from the first air inlet area 2311 enters the first working chamber 211, and the airflow entering from the second air inlet area 2312 enters the second working chamber 212.

[0040] The driving component 3 moves relative to the working chamber 21 to change the relative size of the first working chamber 211 and the second working chamber 212, thereby changing the gas pressure in the first working chamber 211 and the second working chamber 212. By changing the gas pressure, the first working chamber 211 is connected to the air supply chamber 22 or the second working chamber 212 is connected to the air supply chamber 22, so that one of the first working chamber 211 and the second working chamber 212 is connected to the air supply chamber 22.

[0041] In this application, the driving component 3 moves in a direction that is not parallel to the airflow direction in the airflow channel 23, thereby changing the relative size of the first working chamber 211 and the second working chamber 212. Figure 3 and Figure 4In this application, the driving component 3 moves in a direction perpendicular to the airflow direction in the airflow channel 23.

[0042] Optionally, the driving member 3 extends within the airflow channel 23 along the airflow direction within the airflow channel 23, that is, the arrangement direction of the first working chamber 211 and the second working chamber 212 is perpendicular to the airflow direction within the airflow channel 23. The driving member 3 reciprocates relative to the airflow channel 23 along the airflow direction perpendicular to the airflow direction within the airflow channel 23, changing the relative size of the first working chamber 211 and the second working chamber 212. Figure 3 and Figure 4 As shown, the airflow direction in the airflow channel 23 is from left to right, the driving member 3 extends in the left and right direction, the first working chamber 211 is located above the second working chamber 212, and the driving member 3 moves in the up and down direction to change the relative size of the first working chamber 211 and the second working chamber 212.

[0043] The driving component 3 reciprocates within the working cavity 21. Figure 3 and Figure 4 Up-down movement, rather than axial movement. Figure 3 and Figure 4 (Move left and right) By changing the air pressure in the first working chamber 211 and the second working chamber 212, one of the first working chamber 211 and the second working chamber 212 can be connected to the air supply chamber 22.

[0044] Optionally, such as Figure 2 As shown, the vortex ring generator 100 also includes a drive device 1, which includes a retractable push-pull part 11. The push-pull part 11 is driven to be connected to the drive member 3 to drive the drive member 3 to reciprocate relative to the working chamber 21.

[0045] The drive device 1 can be a linear motor, an electromagnetic push rod, or an electric push rod. When the drive device 1 is a linear motor, the push-pull part 11 is the motor shaft of the linear motor. When the drive device 1 is an electromagnetic push rod, the push-pull part 11 is the push rod of the electromagnetic push rod. When the drive device 1 is an electric push rod, the push-pull part 11 is the push rod of the electric push rod.

[0046] Optionally, the partition assembly includes a first partition, a first one-way switch 7, and a second one-way switch 8.

[0047] The first partition divides the airflow channel into a working chamber and an air supply chamber arranged sequentially along the airflow direction, that is, the first partition is located between the working chamber and the air supply chamber.

[0048] The first one-way switch 7 is located between the first working chamber 211 and the air supply chamber 22, and is configured to conduct unidirectionally in the direction from the first working chamber 211 to the air supply chamber 22. In other words, the first one-way switch 7 does not conduct in the direction from the air supply chamber 22 to the first working chamber 211. Under the action of the first one-way switch 7, the airflow can only enter the air supply chamber 22 from the first working chamber 211 and cannot enter the first working chamber 211 from the air supply chamber 22.

[0049] The movement of the driving component 3 relative to the working chamber 21 changes the size of the first working chamber 211 and the second working chamber 212, thereby changing the air pressure in the first working chamber 211 and the second working chamber 212. When the pressure in the first working chamber 211 is greater than a first pressure value, the first one-way switch 7 opens under the action of the pressure in the first working chamber 211 to connect the first working chamber 211 and the air supply chamber 22. The airflow in the first working chamber 211 enters the air supply chamber 22 and flows out from the air outlet 232 of the airflow channel 23 to form a vortex ring.

[0050] The first one-way switch 7 can be activated when the pressure in the first working chamber 211 is greater than the first pressure value, so that the first working chamber 211 is connected to the air supply chamber 22 to realize vortex ring air supply, and can also prevent the airflow in the air supply chamber 22 from flowing back into the first working chamber 211.

[0051] The second one-way switch 8 is located between the second working chamber 212 and the air supply chamber 22, and is configured to conduct unidirectionally in the direction from the second working chamber 212 to the air supply chamber 22. In other words, the second one-way switch 8 does not conduct in the direction from the air supply chamber 22 to the second working chamber 212. Under the action of the second one-way switch 8, the airflow can only enter the air supply chamber 22 from the second working chamber 212 and cannot enter the second working chamber 212 from the air supply chamber 22.

[0052] The movement of the driving component 3 relative to the working chamber 21 changes the size of the first working chamber 211 and the second working chamber 212, thereby changing the air pressure in the first working chamber 211 and the second working chamber 212. When the pressure in the second working chamber 212 is greater than the second pressure value, the second one-way switch 8 opens under the action of the pressure in the second working chamber 212 to connect the second working chamber 212 with the air supply chamber 22. The airflow in the second working chamber 212 enters the air supply chamber 22 and flows out from the air outlet 232 of the airflow channel 23 to form a vortex ring.

[0053] The second one-way switch 8 can be activated when the pressure in the second working chamber 212 is greater than the second pressure value, so that the second working chamber 212 is connected to the air supply chamber 22 to realize vortex air supply, and can also prevent the airflow in the air supply chamber 22 from flowing back into the second working chamber 212.

[0054] Optionally, at least one of the first one-way switch 7 and the second one-way switch 8 is movably disposed within the airflow channel 23 and moves relative to the airflow channel 23 under the action of airflow pressure, so as to realize the opening and closing (opening or closing) of at least one of the first one-way switch 7 and the second one-way switch 8.

[0055] The first one-way switch 7 can be movably disposed within the airflow channel 23. Under the action of air pressure in the first working chamber 211, the first one-way switch 7 abuts against or separates from the first partition 4, thereby realizing the opening or closing of the first one-way switch 7. For example, the first one-way switch 7 can be rotatably disposed within the airflow channel 23, or slidably disposed within the airflow channel 23. Taking the first one-way switch 7 rotatably disposed in the airflow channel 23 as an example, the first one-way switch 7 is rotatably connected to the inner wall of the airflow channel 23 or to the first partition 4. The air pressure in the first working chamber 211 acts on the first one-way switch 7, pushing the first one-way switch 7 to rotate. When the air pressure in the first working chamber 211 is less than or equal to the first pressure value, the first one-way switch 7 abuts against the first partition 4, and the first working chamber 211 is not connected to the air supply chamber 22. When the air pressure in the first working chamber 211 is greater than the first pressure value, under the action of the pressure in the first working chamber 211, the first one-way switch 7 separates from the first partition 4, and the first working chamber 211 is connected to the air supply chamber 22.

[0056] like Figure 3 and Figure 4 As shown, there are gaps between the two ends of the first partition 4 and the inner wall of the airflow channel 23. The upper end of the first partition 4 has an upper gap with the airflow channel 23, and the first one-way switch 7 is located in the upper gap. The upper end of the first one-way switch 7 is rotatably connected to the inner wall of the airflow channel 23. The lower end of the first one-way switch 7 is located inside the air supply chamber 22 (specifically, the first air supply chamber 221). The first one-way switch 7 is inclined towards the air supply chamber 22 along the airflow direction within the airflow channel 23, thus opening the first working chamber 2... When the air pressure in chamber 11 is greater than the first pressure value, the air pressure in the first working chamber 211 pushes the first one-way switch 7 to rotate. The lower end of the first one-way switch 7 rotates counterclockwise, so that the first working chamber 211 is connected to the air supply chamber 22. When the air pressure in the first working chamber 211 is less than or equal to the first pressure value, the air pressure in the first working chamber 211 cannot push the first one-way switch 7 to rotate. The lower end of the first one-way switch 7 abuts against the first partition 4, so that the first working chamber 211 is not connected to the air supply chamber 22.

[0057] The second one-way switch 8 can be movably disposed within the airflow channel 23. Under the action of air pressure within the second working chamber 212, the second one-way switch 8 abuts against or separates from the first partition 4, thereby realizing the opening or closing of the second one-way switch 8. For example, the second one-way switch 8 can be rotatably disposed within the airflow channel 23, or slidably disposed within the airflow channel 23. Taking the second one-way switch 8 rotatably disposed in the airflow channel 23 as an example, the second one-way switch 8 is rotatably connected to the inner wall of the airflow channel 23 or to the first partition 4. The air pressure in the second working chamber 212 acts on the second one-way switch 8, pushing the second one-way switch 8 to rotate. When the air pressure in the second working chamber 212 is less than or equal to the second pressure value, the second one-way switch 8 abuts against the first partition 4, and the second working chamber 212 is not connected to the air supply chamber 22. When the air pressure in the second working chamber 212 is greater than the second pressure value, under the action of the pressure in the second working chamber 212, the second one-way switch 8 separates from the first partition 4, and the second working chamber 212 is connected to the air supply chamber 22.

[0058] like Figure 3 and Figure 4 As shown, there are gaps between the two ends of the first partition 4 and the inner wall of the airflow channel 23. The lower end of the first partition 4 has a lower gap with the airflow channel 23. The second one-way switch 8 is located in the lower gap, and its lower end is rotatably connected to the inner wall of the airflow channel 23. The upper end of the second one-way switch 8 is located inside the air supply chamber 22 (specifically, the second air supply chamber 222). The second one-way switch 8 is inclined towards the air supply chamber 22 along the airflow direction within the airflow channel 23, thus opening the second working chamber 2... When the air pressure in chamber 12 is greater than the second pressure value, the air pressure in the second working chamber 212 pushes the second one-way switch 8 to rotate. The upper end of the second one-way switch 8 rotates clockwise, so that the second working chamber 212 is connected to the air supply chamber 22. When the air pressure in the second working chamber 212 is less than or equal to the second pressure value, the air pressure in the second working chamber 212 cannot push the second one-way switch 8 to rotate. The lower end of the second one-way switch 8 abuts against the first partition 4, so that the second working chamber 212 is not connected to the air supply chamber 22.

[0059] Optionally, such as Figure 3 and Figure 4 As shown, the vortex ring generator 100 also includes a second partition 5.

[0060] The second partition 5 is disposed within the air supply cavity 22 and divides the air supply cavity 22 into a first air supply cavity 221 and a second air supply cavity 222. The air outlet 232 of the airflow channel 23 includes a first air outlet 2321 communicating with the first air supply cavity 221 and a second air outlet 2322 communicating with the second air supply cavity 222. Figure 2As shown, the housing 2 is provided with a first air outlet 2321 and a second air outlet 2322. The first air outlet 2321 is connected to the first air supply cavity 221, and the second air outlet 2322 is connected to the second air supply cavity 222. The number of first air outlets 2321 and the number of second air outlets 2322 can be one or more, as shown in the figure. Figure 2 There are three of each of the first air outlet 2321 and the second air outlet 2322.

[0061] The second partition 5 extends along the direction of airflow within the airflow channel 23, dividing the air supply chamber 22 into a first air supply chamber 221 and a second air supply chamber 222, which are spaced apart. The orientation of the first air supply chamber 221 and the second air supply chamber 222 is perpendicular to the direction of airflow within the airflow channel 23. Figure 3 and Figure 4 As shown, the airflow direction in the airflow channel 23 is from left to right, the second partition 5 extends in the left and right direction, and the first air supply cavity 221 is located above the second air supply cavity 222.

[0062] The first air supply chamber 221 corresponds to the first working chamber 211. A first one-way switch 7 is located between the first working chamber 211 and the first air supply chamber 221 and is unidirectionally open in the direction from the first working chamber 211 to the first air supply chamber 221. It is used to control whether the first working chamber 211 and the first air supply chamber 221 are connected. The second air supply chamber 222 corresponds to the second working chamber 212. A second one-way switch 8 is located between the second working chamber 212 and the second air supply chamber 222 and is unidirectionally open in the direction from the second working chamber 212 to the second air supply chamber 222. It is used to control whether the second working chamber 212 and the second air supply chamber 222 are connected.

[0063] like Figure 3 In the middle, when the driving component 3 is oriented toward the first working cavity 211 (along... Figure 3 When the dashed arrow points upward, the air pressure in the first working chamber 211 increases. When the pressure increases to a value greater than the first pressure value, the first one-way switch 7 opens, and the air in the first working chamber 211 is sent into the first air supply chamber 221. It is then discharged at the first air outlet 2321 in a vortex-like manner, with the airflow direction as follows: Figure 3 As indicated by the solid arrow in the middle.

[0064] like Figure 4 In the middle, when the driving component 3 is oriented towards the second working cavity 212 (along... Figure 4 When the dashed arrow points downwards, the air pressure in the second working chamber 212 increases. When the pressure increases to a value greater than the second pressure value, the second one-way switch 8 opens, and the air in the second working chamber 212 is sent into the second air supply chamber 222. It is then discharged at the second air outlet 2322 in a vortex-like manner, with the airflow direction as follows: Figure 4 As indicated by the solid arrow in the middle.

[0065] The second partition 5 divides the air supply chamber 22 into two independent air supply chambers 221 and 222. This ensures that a vortex ring is generated whenever the drive component 3 moves upward or downward. The first air supply chamber 221 and the second air supply chamber 222 operate alternately, thereby increasing the vortex ring generation frequency and achieving rapid intermittent air supply, thus generating a stable air vortex ring. When the vortex ring generation frequency is determined, the movement speed of the drive component 3 can be reduced, thereby reducing the design requirements of the drive device 1.

[0066] Figure 3 and Figure 4 In the middle, the working chamber is divided into two chambers, the first working chamber and the second working chamber, by the driving component. It can be understood that the working chamber can be divided into more chambers. The air supply chamber is divided into two chambers, the first air supply chamber and the second air supply chamber, by the second partition. It can be understood that the air supply chamber can be divided into more chambers.

[0067] Optionally, such as Figure 3 and Figure 4 As shown, the vortex ring generator 100 also includes a third one-way switch 9 and a fourth one-way switch 10.

[0068] The third one-way switch 9 is located between the first air inlet area 2311 and the first working chamber 211, and is configured to conduct unidirectionally in the direction from the first air inlet area 2311 to the first working chamber 211. In other words, the third one-way switch 9 is not conducting in the direction from the first working chamber 211 to the first air inlet area 2311. Under the action of the third one-way switch 9, airflow can only enter the first working chamber 211 from the first air inlet area 2311 and cannot enter the first air inlet area 2311 from the first working chamber 211. When the pressure in the first working chamber 211 is less than the third pressure value, the first one-way switch 7 opens under the action of the air pressure in the first air inlet area 2311 to connect the first air inlet area 2311 and the first working chamber 211.

[0069] A fourth one-way switch 10 is located between the second air inlet region 2312 and the second working chamber 212. It is configured to conduct unidirectionally from the second air inlet region 2312 to the second working chamber 212. In other words, the fourth one-way switch 10 is not conductive in the direction from the second working chamber 212 to the second air inlet region 2312. Under the action of the fourth one-way switch 10, airflow can only enter the second working chamber 212 from the second air inlet region 2312 and cannot enter the second air inlet region 2312 from the second working chamber 212. When the pressure in the second working chamber 212 is less than the fourth pressure value, the second one-way switch 10 opens under the action of the air pressure in the second air inlet region 2312, thus connecting the second air inlet region 2312 and the second working chamber 212.

[0070] A third one-way switch 9 is provided to control whether airflow is supplied to the first working chamber 211 by opening and closing the third one-way switch 9. A fourth one-way switch 10 is provided to control whether airflow is supplied to the second working chamber 212 by opening and closing the fourth one-way switch 10.

[0071] like Figure 3 and Figure 4 In the process, the driving device 1 drives the driving component 3 to reciprocate within the working chamber 21. During one return stroke, the driving component 3 drives the first one-way switch 7, the second one-way switch 8, the third one-way switch 9, and the fourth one-way switch 10 to open and close intermittently, sending air from the left side of the working chamber 21 into the air supply chamber 22. The air supply chamber 22 is divided into two independent chambers (the first air supply chamber 221 and the second air supply chamber 222) by the second partition 5. Finally, the air is sheared and rolled up at the air outlet 232 of the airflow channel 23 to generate an air vortex ring.

[0072] Specifically, such as Figure 3 As shown, when the drive unit 3 moves vertically upward or moves upward to the first designated position, the air pressure in the first working chamber 211 increases, and the air pressure in the second working chamber 212 decreases. Because the air pressure in the second working chamber 212 decreases, the fourth one-way switch 10 opens, and the airflow in the second air inlet area 2312 enters the second working chamber 212, replenishing the air in the second working chamber 212. Because the air pressure in the first working chamber 211 increases, the first one-way switch 7 opens, sending the air in the first working chamber 211 into the first air supply chamber 221, and then out in the form of a vortex ring at the first air outlet 2321; as... Figure 4 As shown, when the drive unit 3 moves vertically downward or downward to the second designated position, the air pressure in the first working chamber 211 decreases and the air pressure in the second working chamber 212 increases. Due to the decrease in air pressure in the first working chamber 211, the third one-way switch 9 is opened, and the airflow in the first air inlet area 2311 enters the first working chamber 211 to replenish the air in the first working chamber 211. Due to the increase in air pressure in the second working chamber 212, the second one-way switch 8 is opened, and the air in the second working chamber 212 is sent into the second air supply chamber 222 and sent out in the form of a vortex ring at the second air supply port 2322.

[0073] If the method of this application is not adopted, for example, the first partition 4 is not provided in the airflow channel 23, and the driving member 3 extends in the vertical direction and along... Figure 3 and Figure 4 The drive component moves back and forth in the left and right directions; in other words, the drive component moves along the direction of the airflow in the airflow channel. The motion mode diagram of drive component 3 is shown in the figure below. Figure 5As shown, ① is the push stroke of the driving component 3 (the driving component 3 pushes towards the air outlet 232 near the airflow channel 23), and ② is the return stroke of the driving component 3 (the driving component 3 pushes towards the air inlet of the airflow channel 23). ① and ② form a motion cycle. The vortex ring can only be generated under the action of the push stroke of ① and ③. Under the action of the return stroke of ② and ④, external environmental fluid will be drawn in from the air outlet 232 of the airflow channel 23. When the vortex ring is continuously generated in this operating mode, the operating mode of the driving component 3 needs to be considered. Otherwise, it is difficult to guarantee the stability of the air vortex ring and an independent vortex ring structure cannot be realized.

[0074] This application implements a change in the operating mode of the drive component 3, where the drive component moves in a direction that is not parallel to the airflow direction in the airflow channel, such as... Figure 6 As shown, ① represents the push stroke of the first air supply chamber 221, and ② represents the push stroke of the second air supply chamber 222. ① and ② form a motion cycle, thereby improving the efficiency of the vortex ring air supply and avoiding the intake of external environmental fluid during the return stroke. Optionally, the drive device 1 controls the drive component 3 to operate in the mode described in this application, which can increase the generation frequency of the vortex ring, continuously and stably generate the vortex ring, and will not affect the stability of the air vortex ring. During the process of the drive device 1 controlling the drive component 3 to move closer to the first working chamber 211 or the second working chamber 212, the absolute values ​​of the acceleration during the acceleration phase and the deceleration phase of the drive component 3 are equal, so that the drive component 3 uniformly compresses the air in the first working chamber 211 or the second working chamber 212 to generate a stable vortex ring. Taking the upward movement of the driving component 3 controlled by the driving device 1 as an example, the driving component 3 starts moving upward from an initial position with a speed of 0, which is an acceleration process. When the driving component 3 moves upward and approaches the limit position, it decelerates, which is a deceleration process, and its speed is 0 at the limit position. The acceleration of this acceleration process is equal to that of the deceleration process, so that the driving component 3 uniformly compresses the air in the first working chamber 211. It can be understood that the acceleration of this acceleration process and the deceleration process may not be equal. In practical applications, the speed and acceleration of the driving component 3 during its up and down movement can be flexibly controlled and are not limited here.

[0075] Optionally, at least one of the third one-way switch 9 and the fourth one-way switch 10 is movably disposed within the airflow channel 23 and moves relative to the airflow channel 23 under the action of airflow pressure to realize the opening and closing of at least one of the third one-way switch 9 and the fourth one-way switch 10.

[0076] The vortex ring generator 100 also includes a third partition 6, which is located at the air inlet and divides the air inlet into a first air inlet area 2311 and a second air inlet area 2312.

[0077] The third one-way switch 9 can be movably disposed within the airflow channel 23. Under the action of air pressure in the first air inlet area 2311, the third one-way switch 9 abuts against or separates from the third partition 6, thereby realizing the opening or closing of the third one-way switch 9. For example, the third one-way switch 9 can be rotatably disposed within the airflow channel 23, or slidably disposed within the airflow channel 23. Taking the third one-way switch 9 rotatably located in the airflow channel 23 as an example, the third one-way switch 9 is rotatably connected to the inner wall of the airflow channel 23 or to the third partition 6. The air pressure in the first air inlet area 2311 acts on the third one-way switch 9, pushing the third one-way switch 9 to rotate. When the air pressure in the first working chamber 211 is greater than or equal to the third pressure value, the third one-way switch 9 abuts against the third partition 6, and the first air inlet area 2311 is not connected to the first working chamber 211. When the air pressure in the first working chamber 211 is less than the third pressure value, under the pressure in the first air inlet area 2311, the third one-way switch 9 separates from the third partition 6, and the first air inlet area 2311 is connected to the first working chamber 211.

[0078] like Figure 3 and Figure 4 As shown, there are gaps between the two ends of the third partition 6 and the inner wall of the airflow channel 23. The upper end of the third partition 6 has an upper gap with the airflow channel 23, and the third one-way switch 9 is disposed in this upper gap. The upper end of the third one-way switch 9 is rotatably connected to the inner wall of the airflow channel 23, and the lower end of the third one-way switch 9 is disposed in the first working chamber 211. The third one-way switch 9 is inclined towards the first working chamber 211 along the airflow direction within the airflow channel 23, so that the air pressure in the first working chamber 211 is less than that in the third one-way switch 23. When the pressure value is reached, the air pressure in the first air intake area 2311 drives the third one-way switch 9 to rotate. The lower end of the third one-way switch 9 rotates counterclockwise, so that the first air intake area 2311 is connected to the first working chamber 211. When the air pressure in the first working chamber 211 is greater than or equal to the third pressure value, the air pressure in the first air intake area 2311 cannot drive the third one-way switch 9 to rotate. The lower end of the third one-way switch 9 abuts against the third partition 6, so that the first air intake area 2311 is not connected to the first working chamber 211.

[0079] The fourth one-way switch 10 can be movably disposed within the airflow channel 23. Under the action of air pressure in the second air inlet area 2312, the fourth one-way switch 10 abuts against or separates from the third partition 6, thereby realizing the opening or closing of the fourth one-way switch 10. For example, the fourth one-way switch 10 can be rotatably disposed within the airflow channel 23, or slidably disposed within the airflow channel 23. Taking the fourth one-way switch 10 rotatably disposed in the airflow channel 23 as an example, the fourth one-way switch 10 is rotatably connected to the inner wall of the airflow channel 23 or rotatably connected to the third partition 6. The air pressure in the second air inlet area 2312 acts on the fourth one-way switch 10, pushing the fourth one-way switch 10 to rotate. When the air pressure in the second working chamber 212 is greater than or equal to the fourth pressure value, the fourth one-way switch 10 abuts against the third partition 6, and the second air inlet area 2312 is not connected to the second working chamber 212. When the air pressure in the second working chamber 212 is less than the fourth pressure value, under the action of the pressure in the second air inlet area 2312, the fourth one-way switch 10 separates from the third partition 6, and the second air inlet area 2312 is connected to the second working chamber 212.

[0080] like Figure 3 and Figure 4 As shown, there is an upper gap between the lower end of the third partition 6 and the airflow channel 23. The fourth one-way switch 10 is located in the lower gap, and the lower end of the fourth one-way switch 10 is rotatably connected to the inner wall of the airflow channel 23. The upper end of the fourth one-way switch 10 is located in the second working chamber 212. The fourth one-way switch 10 is inclined towards the second working chamber 212 along the airflow direction in the airflow channel 23. When the air pressure in the second working chamber 212 is less than the fourth pressure value, the air pressure in the second air intake area 2312 pushes the fourth one-way switch 10 to rotate. The upper end of the fourth one-way switch 10 rotates clockwise, so that the second air intake area 2312 is connected to the second working chamber 212. When the air pressure in the second working chamber 212 is greater than or equal to the fourth pressure value, the air pressure in the second air intake area 2312 cannot push the fourth one-way switch 10 to rotate. The lower end of the fourth one-way switch 10 abuts against the third partition 6, so that the second air intake area 2312 is not connected to the second working chamber 212.

[0081] Optionally, the first one-way switch 7, the second one-way switch 8, the third one-way switch 9, and the fourth one-way switch 10 are all plate-shaped, thereby increasing the contact area with the airflow and enabling them to open or close under the action of air pressure. In a specific embodiment, the first one-way switch 7, the second one-way switch 8, the third one-way switch 9, and the fourth one-way switch 10 are all vane valves.

[0082] This disclosure also provides an air conditioning device 200, including an indoor unit and a vortex generator 100 as described in any of the above embodiments.

[0083] The indoor unit includes a casing 21, inside which a heat exchange air duct is provided. The air outlet 211 and the air inlet of the heat exchange air duct are both located on the casing 21. A fan and a heat exchanger are provided inside the heat exchange air duct. Under the action of the fan, the airflow enters the heat exchange air duct through the air inlet and exchanges heat with the heat exchanger. The air after heat exchange flows out through the air outlet of the heat exchange air duct.

[0084] The vortex ring generator 100 is located at the air outlet 211 of the heat exchange air duct (i.e., the air outlet of the heat exchange air duct) and is connected to the air outlet of the heat exchange air duct. The airflow flowing out of the air outlet of the heat exchange air duct enters the air inlet of the airflow channel 23 and is sent out from the air outlet 232 of the airflow channel 23 under the action of the driving component 3 to form a vortex ring.

[0085] The flow area of ​​the heat exchange duct outlet 211 is greater than or equal to the flow area of ​​the air outlet 232 of the airflow channel 23. Here, the air outlet 232 of the airflow channel 23 refers to the total flow area of ​​all air outlets 232 of the airflow channel 23. When fluid flows in the channel, the cross section of the channel perpendicular to the flow direction is called the flow cross section, and the area of ​​the flow cross section is called the flow area.

[0086] When the flow area of ​​the air outlet of the heat exchange duct is equal to the flow area of ​​the air supply outlet 232 of the airflow channel 23, the vortex generator 100 occupies the entire air outlet of the heat exchange duct, and the airflow at the air outlet 211 of the heat exchange duct can be completely sent out through the air supply outlet 232 of the airflow channel 23. All the airflow flowing out of the air outlet of the heat exchange duct is sent to the room in the form of a vortex.

[0087] When the flow area of ​​the outlet of the heat exchange duct is greater than the flow area of ​​the air outlet 232 of the airflow channel 23, the vortex generator 100 occupies part of the outlet of the heat exchange duct. A portion of the airflow from the outlet 211 of the heat exchange duct is sent out in the form of a vortex ring through the air outlet 232 of the airflow channel 23. The other portion of the airflow from the outlet 211 of the heat exchange duct does not enter the airflow channel 23 and is not sent out in the form of a vortex ring. This ensures that the other portion of the airflow from the outlet 211 of the heat exchange duct is sent out in the form of normal air supply, thus guaranteeing the air supply volume of the air conditioning equipment 200.

[0088] The air conditioning device 200 provided in this embodiment includes the vortex ring generator of any of the above embodiments, and therefore has all the beneficial effects of the vortex ring generator 100 of any of the above embodiments, which will not be repeated here.

[0089] Optionally, there may be multiple vortex ring generators 100, which are spaced apart within the heat exchange duct outlet 211.

[0090] Setting up multiple vortex generators 100 can increase the amount of vortex generated, further increasing the air delivery distance. Furthermore, by specifically setting the positions of multiple vortex generators 100, the location of vortex generation can be controlled, thereby controlling the air delivery of the air conditioning equipment 200.

[0091] Multiple vortex generators 100 are spaced apart, meaning there is a gap between two adjacent vortex generators 100, so that the flow area of ​​the air outlet of the heat exchange duct is greater than the flow area of ​​the air outlet 232 of the airflow channel 23, ensuring the air volume of the air conditioning equipment 200.

[0092] Optionally, two of the multiple vortex generators 100 are located at opposite ends of the outlet length of the heat exchange duct. For example... Figure 1 Taking a cabinet-type air conditioner as an example, the heat exchange air duct outlet 211 is elongated, and there are two vortex generators 100, located at opposite ends of the elongated section. This ensures normal airflow (non-vortex type) in the middle of the elongated section, thus guaranteeing the airflow of the air conditioning unit 200. Figure 7 Taking a wall-mounted air conditioner as an example, the heat exchange air duct outlet 211 is long and narrow, and there are two vortex generators 100, which are located at both ends of the length of the long strip. In this way, the middle part of the long strip is for normal air outlet (non-vortex type air outlet), thereby ensuring the air volume of the air conditioning equipment 200.

[0093] In summary, the vortex ring generator provided in this application utilizes a driving device to achieve up-and-down translation of the driving component within the working chamber, thereby intermittently supplying air to the first and second air supply chambers respectively. The first and second air supply chambers operate alternately under the pushing and returning action of the driving component, ultimately shearing and generating air vortices at the first and second air supply ports. This invention avoids the problem of ambient air being drawn into the chamber by alternating operation of the two air supply chambers (the first and second air supply chambers). Under the pushing and returning action of the driving component, air enters the upper and lower air supply chambers (the first and second air supply chambers) respectively, ultimately generating air vortices. The air supply speed of this vortex ring generator is determined by the operating speed of the driving device.
