Description

Technical Field

[0001] This invention relates to the field of air outlet equipment technology, and in particular to an airflow regulation method and an air outlet equipment. Background Technology

[0002] Air outlet devices, especially common air conditioners, often produce a direct blowing sensation. For example, in cooling mode, a user's skin may feel too cold when exposed to high-speed cold air, causing discomfort.

[0003] Furthermore, existing air conditioners lack the function of zoned, independent temperature control. For example, when it is necessary to quickly adjust the temperature of objects close to the air conditioner (such as sofa sets in the living room or dining tables in the dining room), existing air conditioners often use high-temperature energy control and high-speed airflow to blow directly onto the objects close to the air conditioner, causing discomfort to the user. When it is necessary to quickly adjust the temperature of objects far from the air conditioner, existing air conditioners will also use the same airflow method. In this case, the existing air conditioner will first blow air onto the objects close to the air conditioner, and then the remaining airflow will blow air onto the objects far away from the air conditioner. This has the disadvantage of poor temperature adjustment effect and causes inconvenience to the user. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides an airflow regulation method to optimize the problem of uneven temperature regulation at different distances caused by the airflow distribution defects of existing air outlet equipment, and to achieve a more flexible temperature regulation air outlet effect.

[0005] Another objective of this invention is to provide an air outlet device to optimize the problem of uneven temperature regulation at different distances caused by the airflow distribution defects of existing air outlet devices.

[0006] The technical solution adopted by this invention to solve its problem is:

[0007] According to one aspect of the present invention, an airflow regulation method is provided, which is applicable to an air outlet device, the air outlet device including a first air outlet system and a second air outlet system arranged sequentially in an upward and downward direction, the airflow regulation method includes: step S1: operating the first air outlet system and the second air outlet system; step S2: when it is necessary to increase the airflow delivery distance, at least a portion of the airflow in the air path of the second air outlet system is drawn into the first air outlet system.

[0008] In this way, when a large-scale, long-distance airflow is needed for rapid temperature regulation, the first and second air outlet systems are activated, allowing both systems to operate simultaneously. The first air outlet system draws a portion of the airflow from the second air outlet system's air path as its intake, thereby increasing the airflow volume of the first system and decreasing the airflow volume of the second system. Since the first and second air outlet systems are arranged vertically on the air outlet equipment, the high-velocity, high-volume temperature-regulating airflow emitted by the first system, after being blown out from the top of the air outlet equipment, can reach locations farther away, achieving a wider range of temperature control. Conversely, because the second air outlet system is located below the air outlet equipment, its low-velocity, low-volume temperature-regulating airflow can be directed towards objects closer to the air outlet equipment (such as sofa sets in the living room or dining tables in the dining room). Meanwhile, because the high-speed, high-volume temperature-regulating airflow emitted by the first air outlet system blows out from the top of the air outlet device, it avoids the temperature-regulating objects that are close to the air outlet device. This achieves balanced temperature regulation for objects near or far from the air outlet device, and at the same time reduces the feeling of direct blowing, improving the user's comfort in receiving the airflow from the air outlet device. Moreover, in this way, the high-speed, high-volume temperature-regulating airflow emitted by the first air outlet system regulates the temperature of areas far from the air outlet device, causing the temperature regulation effect to spread from areas far from the air outlet device to areas close to the air outlet device. This achieves temperature regulation from far to near, avoiding or slowing down the dissipation of the temperature regulation energy blown by the second air outlet system from areas close to the air outlet device to areas far from the air outlet device. This maintains the temperature regulation effect in areas close to the air outlet device, thus achieving the function of regional temperature control and providing a better overall temperature regulation effect.

[0009] Preferably, step S2 includes a first operating mode 2.1, which is:

[0010] The first air outlet system draws in air that has not undergone heat exchange treatment by the second air outlet system.

[0011] In this way, due to the adoption of this working mode, the first air outlet system draws in air that has not undergone heat exchange treatment by the second air outlet system. Therefore, the temperature control energy of the second air outlet system is not reduced. That is, without changing the temperature control energy of the second air outlet system, the air volume of the second air outlet system is reduced. This results in the low-speed, low-volume temperature-regulating airflow emitted by the second air outlet system being blown out from the bottom of the air outlet equipment and directed towards the object being regulated (such as the sofa set in the living room or the dining table in the dining room), which has the characteristic of low draft.

[0012] Preferably, the first operating mode 2.1 includes:

[0013] Mode 2.1(a): The first air outlet system draws airflow from the intake air path of the second air outlet system; and

[0014] Mode 2.1(b): The first air outlet system draws airflow from the air outlet path of the second air outlet system.

[0015] Thus, in mode 2.1(a), since the air intake path of the second air outlet system is not driven by acceleration, the airflow has the characteristics of low initial velocity and large volume. Therefore, in this mode, the first air outlet system obtains high wind speed and high air flow by increasing the air intake volume.

[0016] In mode 2.1(b), the first air outlet system draws in the airflow from the second air outlet system that has not undergone heat exchange treatment. At that time, the airflow drawn in has a high speed at the outlet position. Therefore, it can provide the first air outlet system with a high-speed airflow, achieving a higher speed and larger airflow for the first air outlet system.

[0017] Preferably, in the first air outlet system and the second air outlet system, at least the second air outlet system is capable of heat exchange treatment of the airflow. Step S2 includes a second operating mode 2.2, which is:

[0018] The first air outlet system draws in the heat-treated airflow from the outlet air path of the second air outlet system.

[0019] Thus, since the airflow in the outlet air path of the second air outlet system is the airflow that has been accelerated and heat-exchanged by the second air outlet system, the airflow has both temperature control energy and a high blowing speed. When the air outlet device is in the second working mode 2.2, the first air outlet system draws the airflow from the outlet air path of the second air outlet system. After the first air outlet system draws the airflow with high initial wind speed and temperature control energy, it undergoes further acceleration and heat exchange by the first air outlet system. Compared with the first working mode, the first air outlet system emits airflow with stronger temperature control function and higher outlet wind speed, thus enabling the first air outlet system to obtain stronger temperature control adjustment capability and a larger temperature control adjustment range.

[0020] According to another aspect of the present invention, the present invention provides an air outlet device, including a first air outlet system and a second air outlet system arranged sequentially in an upward and downward direction, wherein at least the second air outlet system is capable of heat exchange treatment of the airflow; wherein the first air outlet system is provided with a first air intake, the first air intake is connected to the air passage of the second air outlet system to draw airflow from the air passage of the second air outlet system.

[0021] In this way, the first air intake of the first air outlet system is connected to the air path of the second air outlet system. Therefore, when a large-scale, long-distance airflow is needed for rapid temperature regulation, both the first and second air outlet systems are activated, allowing them to operate simultaneously. The first air outlet system draws a portion of the airflow from the second air outlet system's air path as its intake, increasing the airflow volume of the first system and decreasing the airflow volume of the second system. This allows the high-velocity, high-volume temperature-regulating airflow from the first air outlet system to reach a greater distance from the outlet, achieving a wider temperature control effect. Simultaneously, the low-velocity, low-volume temperature-regulating airflow from the second air outlet system can... By directing the temperature-controlled airflow towards objects closer to the air outlet, the system achieves balanced temperature control for objects near or far from the air outlet. This also reduces the feeling of direct airflow, improving user comfort when receiving airflow from the air outlet. Furthermore, the high-speed, high-volume airflow from the first air outlet system regulates the temperature of areas far from the air outlet, allowing the temperature-regulating effect to spread from those areas closer to the air outlet. This achieves temperature control from a distance, preventing or mitigating the dissipation of temperature-regulating energy from the second air outlet system from areas near the air outlet to areas further away. This maintains the temperature control effect in areas near the air outlet, thus achieving zoned temperature regulation and providing a superior overall temperature control effect.

[0022] Preferably, the air outlet device is provided with an air inlet driving component, which is used to drive the first air inlet to move between the air inlet and air outlet of the second air outlet system, so as to connect the first air inlet with the air inlet and / or air outlet of the second air outlet system.

[0023] In this way, the first air intake can be moved along the air inlet and outlet paths of the second air outlet system by the air intake drive component, thereby connecting the first air intake with the air inlet or outlet path of the second air outlet system. Therefore, the first air intake can be connected to the air inlet path of the second air outlet system by the air intake drive component to obtain a large flow of high-speed airflow, thereby expanding the temperature control range. The first air intake can also be connected to the air outlet path of the second air outlet system by the air intake drive component to obtain a high-speed airflow with high temperature control energy, further expanding the temperature control range and allowing users to switch between the two air outlet modes according to their needs.

[0024] Preferably, the second air outlet system includes a heat exchange device and an air outlet fan. The heat exchange device and the air outlet fan are arranged sequentially along the air path of the second air outlet system. The air inlet is located upstream of the air outlet fan, the air outlet is located downstream of the air outlet fan, and the first air intake is located upstream or downstream of the air outlet fan.

[0025] In this way, since the heat exchange device and the outlet fan are arranged sequentially along the air path of the second air outlet system, when the outlet fan is working, the outlet fan generates a suction airflow on the side near the heat exchange device to draw indoor air through the heat exchange device. After being accelerated by the outlet fan, the air is blown out from the side away from the heat exchange device. That is, an inlet air path is formed on the side of the outlet fan near the heat exchange device, and an outlet air path is formed on the side of the outlet fan away from the heat exchange device. This achieves the formation of an inlet air path upstream of the outlet fan and an outlet air path downstream of the outlet fan in the air path of the second air outlet system. Thus, the first air inlet can be located upstream or downstream of the outlet fan to draw in airflows with different speeds and temperature characteristics to meet the actual temperature control needs.

[0026] Preferably, the air path of the second air outlet system is pre-set with a first transfer position and a second transfer position, wherein the first transfer position is located upstream of the air outlet fan and the second transfer position is located downstream of the air outlet fan, and the air intake drive assembly drives the first air intake to move to the first transfer position or the second transfer position.

[0027] Thus, when the air intake drive assembly drives the first air intake to the first transfer position, the first air intake is located in the air intake path of the second air outlet system, and the first air outlet system can draw in low-speed, high-flow air without heat exchange treatment; when the air intake drive assembly drives the first air intake to the second transfer position, the first air intake is located in the air outlet path of the second air outlet system, and the first air outlet system can draw in high-speed air without heat exchange or with heat exchange treatment.

[0028] Preferably, the first air outlet system includes a drive fan, and the first air inlet is connected to the air inlet of the drive fan;

[0029] The air intake drive assembly includes a drive motor, a drive gear, and a driven gear. The drive gear is driven and connected to the output shaft of the drive motor. The drive gear and the driven gear are meshed and paired. The driven gear is fixed to the drive fan. The drive fan is pivotally mounted in the air outlet device and connects the first air intake to the air inlet or air outlet of the second air outlet system.

[0030] Thus, when the drive fan is working, it generates a strong suction force, which in turn causes the first air intake of the first air outlet system to generate suction. When the drive motor is working, it drives the drive gear to rotate. Under the meshing transmission action of the drive gear and the driven gear, the drive gear drives the driven gear to drive the drive fan to rotate, causing the first air intake of the first air outlet system to rotate between the air inlet and air outlet of the second air outlet system. That is, when the drive motor is working, the drive gear can drive the driven gear to drive the drive fan to rotate, so that the suction direction of the first air intake is biased to connect with the air inlet of the second air outlet system. In this way, the second air outlet system can draw in low-speed, high-flow-rate airflow that has not undergone heat exchange treatment. When the drive motor is working, the drive gear can drive the driven gear to drive the drive fan to rotate, so that the suction direction of the first air intake is biased to connect with the air outlet of the second air outlet system. In this way, the second air outlet system can draw in high-speed airflow that has not undergone heat exchange or has undergone heat exchange treatment.

[0031] Preferably, the air outlet device is provided with a first mounting cavity, a second mounting cavity, a first air outlet and a second air outlet, wherein the first air outlet is connected to the first mounting cavity, the second air outlet is connected to the second mounting cavity, the first mounting cavity and the second mounting cavity are isolated from each other, the first air outlet system is disposed in the first mounting cavity, and the second air outlet system is disposed in the second mounting cavity.

[0032] A first drain port and a second drain port are respectively provided between the first mounting cavity and the second mounting cavity, wherein the first drain port extends between the heat exchange device and the air outlet fan, and the second drain port extends between the air outlet fan and the second air outlet;

[0033] The first air intake port connects to either the first air outlet or the second air outlet as the drive fan rotates.

[0034] Thus, since the first mounting cavity and the second mounting cavity are isolated from each other, a first drain port and a second drain port are also provided between the first mounting cavity and the second mounting cavity. The first drain port extends between the heat exchange device and the outlet fan, and the second drain port extends between the outlet fan and the second outlet. When the air outlet equipment is in the first working mode, the suction port drive assembly drives the first suction port to move to the first transfer position, and the first suction port is connected to the first drain port to draw the airflow of the intake airflow of the second air outlet system. When the air outlet equipment is in the second working mode, the suction port drive assembly drives the first suction port to move to the second transfer position, and the first suction port is connected to the second drain port to draw the airflow of the outlet air path of the second air outlet system.

[0035] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0036] 1) An airflow regulation method is provided. When a large-scale, long-distance airflow needs to be transmitted for rapid temperature regulation, a portion of the airflow in the air path of the second air outlet system is drawn in by the first air outlet system and used as the intake air of the first air outlet system, thereby increasing the airflow of the first air outlet system and decreasing the airflow of the second air outlet system. This achieves balanced temperature regulation of the object being regulated, whether near or far from the air outlet equipment. At the same time as regulating the temperature, it also reduces the feeling of direct blowing, improves the user's comfort in receiving the airflow from the air outlet equipment, and has the function of regional temperature regulation. Overall, it has a better temperature regulation effect.

[0037] 2) This airflow regulation method also has two working modes. The first working mode includes two sub-working modes, namely mode 2.1(a) and mode 2.1(b). In mode 2.1(a), the first air outlet system obtains high wind speed and high air flow by increasing the air intake. In mode 2.1(b), it can provide high-speed airflow to the second air outlet system, achieving higher air speed and air flow for the second air outlet system. Compared with the first working mode, the first air outlet system can emit airflow with stronger temperature control function and higher air speed in the second working mode, thus achieving stronger temperature control regulation capability and a wider temperature control regulation range for the first air outlet system.

[0038] 3) An air outlet device is proposed that, when a large-scale, long-distance airflow is required for rapid temperature adjustment, a portion of the airflow in the air path of the second air outlet system is drawn in by the first air outlet system and used as the intake air of the first air outlet system, thereby increasing the airflow of the first air outlet system and decreasing the airflow of the second air outlet system. This achieves balanced temperature adjustment for objects near or far from the air outlet device, and reduces the direct blowing sensation while adjusting the temperature, improving the user's comfort in receiving the airflow from the air outlet device. It also has the function of regional temperature control and has a better overall temperature adjustment effect.

[0039] 4) The air outlet device is also equipped with an air intake drive component, which can drive the first air intake of the first air outlet system to switch between the air intake and air outlet paths of the second air outlet system. This allows the air outlet device to change its air outlet working mode to meet the air outlet needs of different users, and the switching is convenient. Attached Figure Description

[0050] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings.

[0054] Example 1

[0055] Figures 1-7 Some illustrative embodiments of the air outlet device of the present invention are shown.

[0056] This embodiment discloses an air outlet device. Specifically, the air outlet device is a fan, an air conditioner, or other air outlet device with cooling and / or heating functions.

[0057] refer to Figure 1 In this embodiment, the air outlet device includes a first air outlet system 1 and a second air outlet system 2 arranged sequentially in the upward and downward directions. At least the second air outlet system 2 can perform heat exchange treatment on the airflow. The first air outlet system 1 is provided with a first air intake 101, which is connected to the air passage of the second air outlet system 2 to draw airflow from the air passage of the second air outlet system 2.

[0058] Therefore, when a large-scale, long-distance airflow is needed for rapid temperature regulation, the first air outlet system 1 and the second air outlet system 2 are activated, allowing both systems to operate simultaneously. The first air outlet system 1 draws in a portion of the airflow from the air path of the second air outlet system 2, using it as its intake air, thus increasing the output airflow of the first air outlet system 1 and decreasing the output airflow of the second air outlet system 2. This allows the high-velocity, high-volume temperature-regulating airflow from the first air outlet system 1 to reach locations farther from the outlet, achieving a wider temperature control effect. Simultaneously, the low-velocity, low-volume temperature-regulating airflow from the second air outlet system 2 can be directed towards objects closer to the outlet (e.g., customers). (The sofa set in the hall, the dining table in the dining room), thus achieving uniform temperature regulation for objects near or far from the air outlet, while reducing the feeling of direct airflow and improving the user's comfort in receiving the airflow from the air outlet. Moreover, in this way, the high-speed, high-volume temperature-regulating airflow emitted by the first air outlet system 1 regulates the temperature of areas far from the air outlet, causing the temperature regulation effect to spread from areas far from the air outlet to areas near the air outlet, achieving temperature regulation from far to near. This avoids or slows down the dissipation of the temperature regulation energy blown by the second air outlet system 2 from areas near the air outlet to areas far from the air outlet, thereby maintaining the temperature regulation effect in areas near the air outlet. In other words, it achieves the function of regional temperature control, and has a better overall temperature regulation effect.

[0059] refer to Figure 1 Furthermore, both the first air outlet system 1 and the second air outlet system 2 may include a heat exchange device 3, such as a common evaporator, or only the first air outlet system 1 or the second air outlet system 2 may include a heat exchange device 3, or neither the first air outlet system 1 nor the second air outlet system 2 may include a heat exchange device 3. In this case, the air outlet equipment only transports airflow and cannot perform heat exchange treatment on the airflow, such as heating or cooling.

[0060] refer to Figure 3 , 4 Preferably, the air outlet device is provided with an air inlet driving component 4, which is used to drive the first air inlet 101 to move between the air inlet passage 201 and the air outlet passage 202 of the second air outlet system 2, so that the first air inlet 101 is connected to the air inlet passage 201 and / or the air outlet passage 202 of the second air outlet system 2.

[0061] In this way, the first air intake 101 can be moved along the air inlet passage 201 and air outlet passage 202 of the second air outlet system 2 by the air intake drive component 4, thereby connecting the first air intake 101 with the air inlet passage 201 or air outlet passage 202 of the second air outlet system 2. Therefore, the first air intake 101 can be connected with the air inlet passage 201 of the second air outlet system 2 by the air intake drive component 4 to obtain a high-speed airflow, thereby expanding the temperature control range; the air intake drive component 4 can also be used to drive the first air intake 101 to connect with the air inlet passage 201 of the second air outlet system 2, thereby obtaining a high-flow-rate high-speed airflow and expanding the temperature control range. The first air intake 101 is connected to the air outlet 202 of the second air outlet system 2 to obtain high-speed airflow with high temperature control energy, further expanding the temperature adjustment range and making it convenient for users to switch according to their own needs. Of course, the first air intake 101 can also be adjusted to connect with the air inlet 201 and the air outlet 202 of the second air outlet system 2, so that air can be drawn from the air inlet 201 and the air outlet 202 of the second air outlet system 2 at the same time to meet the mixed air and greater air outlet demand.

[0062] refer to Figure 1 , Figure 3 , Figure 4 In this embodiment, the second air outlet system 2 includes a heat exchange device 3 and an air outlet fan 5. The heat exchange device 3 and the air outlet fan 5 are arranged sequentially along the air passage of the second air outlet system 2. The air inlet passage 201 is located upstream of the air outlet fan 5, the air outlet passage 202 is located downstream of the air outlet fan 5, and the first air intake 101 is located upstream or downstream of the air outlet fan 5.

[0063] In this way, since the heat exchange device 3 and the outlet fan 5 are arranged sequentially along the air path of the second air outlet system 2, when the outlet fan 5 is working, the outlet fan 5 generates a suction airflow on the side close to the heat exchange device 3 to draw indoor air through the heat exchange device 3. After being accelerated by the outlet fan 5, the air is blown out from the side away from the heat exchange device 3. That is, an inlet air path 201 is formed on the side of the outlet fan 5 close to the heat exchange device 3, and an outlet air path 202 is formed on the side of the outlet fan 5 away from the heat exchange device 3. This achieves the formation of an inlet air path 201 upstream of the outlet fan 5 and an outlet air path 202 downstream of the outlet fan 5 in the air path of the second air outlet system 2. Thus, the first air intake 101 can be located upstream or downstream of the outlet fan 5 to draw in airflows with different speeds and temperature characteristics to meet the actual temperature control needs.

[0064] Preferably, the air path of the second air outlet system 2 is pre-set with a first transfer position (not marked in the figure) and a second transfer position (not marked in the figure). The first transfer position is set upstream of the air outlet fan 5, and the second transfer position is set downstream of the air outlet fan 5. The air intake drive assembly 4 drives the first air intake 101 to move to the first transfer position or the second transfer position.

[0065] Thus, when the air intake drive assembly 4 drives the first air intake 101 to the first transfer position, the first air intake 101 is located on the air inlet passage 201 of the second air outlet system 2, and the second air outlet system 2 can draw in low-speed, high-flow air without heat exchange treatment; when the air intake drive assembly 4 drives the first air intake 101 to the second transfer position, the first air intake 101 is located on the air outlet passage 202 of the second air outlet system 2, and the second air outlet system 2 can draw in high-speed air without heat exchange or with heat exchange treatment.

[0066] refer to Figure 3 In one possible implementation, the first air intake 101 is disposed on a retractable connecting air pipe 1011. The air intake drive assembly 4 includes a retractable drive member 401 that drives the first air intake 101 on the connecting air pipe 1011 to switch and move at a first transfer position or a second transfer position of the air inlet passage 201 of the second air outlet system 2, so that the first air intake 101 on the connecting air pipe 1011 is connected to the air inlet passage 201 or the air outlet passage 202.

[0067] Furthermore, the telescopic drive component 401 can be one of an electric, pneumatic, or hydraulic telescopic rod, or it can be other linear drive devices in the prior art, such as a gear and rack drive structure, a lead screw and nut drive structure, etc.

[0068] refer to Figure 3 Furthermore, a solenoid valve 6 can be installed at the first transfer position and the second transfer position to control the airflow connection at the corresponding positions. Specifically, when the first air intake 101 is located at the first transfer position, the solenoid valve 6 at the first transfer position is open, while the solenoid valve 6 at the second transfer position is closed, thereby reducing air leakage in the air outlet passage 202 of the second air outlet system 2; when the first air intake 101 is located at the second transfer position, the solenoid valve 6 at the second transfer position is open, while the solenoid valve 6 at the first transfer position is closed, thereby reducing air leakage in the air inlet passage 201 of the second air outlet system 2.

[0069] In other possible implementations, the first air inlet 101 can be driven to swing to achieve docking of the first air inlet 101 with the first transfer position or the second transfer position of the air inlet passage 201 of the second air outlet system 2.

[0070] refer to Figure 1 , Figure 3 , Figure 4 In a preferred embodiment, the first air outlet system 1 includes a drive fan 7, and the first air inlet 101 is connected to the air inlet of the drive fan 7.

[0071] The air intake drive assembly 4 includes a drive motor 402, a drive gear 403, and a driven gear 404. The drive gear 403 is driven and connected to the output shaft of the drive motor 402. The drive gear 403 and the driven gear 404 are meshed and paired. The driven gear 404 is fixed to the drive fan 7. The drive fan 7 is pivotally mounted in the air outlet device and connects the first air intake 101 to the air inlet passage 201 or the air outlet passage 202 of the second air outlet system 2.

[0072] Thus, when the drive fan 7 is working, it generates a strong suction force, causing the first air intake 101 of the first air outlet system 1 to generate suction. When the drive motor 402 is working, it drives the drive gear 403 to rotate. Under the meshing transmission action of the drive gear 403 and the driven gear 404, the drive gear 403 drives the driven gear 404 to drive the drive fan 7 to rotate, causing the first air intake 101 of the first air outlet system 1 to rotate between the air inlet passage 201 and the air outlet passage 202 of the second air outlet system 2. That is, when the drive motor 402 is working... When the drive motor 402 is working, the drive gear 403 can drive the driven gear 404 to rotate the drive fan 7, so that the suction direction of the first air inlet 101 is biased to connect with the air inlet of the second air outlet system 2. When the drive motor 402 is working, the drive gear 403 can drive the driven gear 404 to rotate the drive fan 7, so that the suction direction of the first air inlet 101 is biased to connect with the air outlet passage 202 ...

[0073] refer to Figure 1 , Figure 4 Furthermore, in this embodiment, the air outlet device includes an annular air outlet structure 8, which is connected to the air outlet passages 202 of the first air outlet system 1 and the second air outlet system 2. That is, both the first air outlet system 1 and the second air outlet system 2 can output airflow to the annular air outlet structure 8, and the annular air outlet structure 8 performs annular air outlet.

[0074] The annular air outlet structure 8 includes an outer frame 801 connected to the main body of the air outlet device and a baffle 802. The baffle 802 is located inside the outer frame 801 and the circumferential side of the baffle 802 is spaced apart from the outer frame 801 to form an annular air outlet, reducing the feeling of direct airflow.

[0075] refer to Figure 1 , Figures 5-7Preferably, the air outlet device is provided with a first mounting cavity 9, a second mounting cavity 10, a first air outlet 11 and a second air outlet 12, wherein the first air outlet 11 is connected to the first mounting cavity 9, the second air outlet 12 is connected to the second mounting cavity 10, the first mounting cavity 9 and the second mounting cavity 10 are isolated from each other, the first air outlet system 1 is disposed in the first mounting cavity 9, and the second air outlet system 2 is disposed in the second mounting cavity 10;

[0076] A first drain port 13 and a second drain port 14 are respectively provided between the first mounting cavity 9 and the second mounting cavity 10, wherein the first drain port 13 extends between the heat exchange device 3 and the air outlet fan 5, and the second drain port 14 extends between the air outlet fan 5 and the second air outlet 12.

[0077] The first air intake 101 is connected to the first air outlet 13 or the second air outlet 14 as the drive fan 7 rotates.

[0078] Thus, since the first mounting cavity 9 and the second mounting cavity 10 are isolated from each other, a first drain port 13 and a second drain port 14 are also provided between the first mounting cavity 9 and the second mounting cavity 10. The first drain port 13 extends between the heat exchange device 3 and the outlet fan 5, and the second drain port 14 extends between the outlet fan 5 and the second outlet 12. When the air outlet device is in one working mode, the suction port drive assembly 4 drives the first suction port 101 to move to the first transfer position, and the first suction port 101 is connected to the first drain port 13 to draw the airflow of the intake airflow of the second air outlet system 2. When the air outlet device is in another working mode, the suction port drive assembly 4 drives the first suction port 101 to move to the second transfer position, and the first suction port 101 is connected to the second drain port 14 to draw the airflow of the outlet air passage 202 of the second air outlet system 2.

[0079] refer to Figure 1 Furthermore, the second inlet 14 is connected to the annular air outlet channel. The first inlet 13 and the second inlet 14 are respectively provided with a first opening and closing structure 15 and a second opening and closing structure 16. The first opening and closing structure 15 is used to control the conduction state of the first inlet 13, and the second opening and closing structure 16 is used to control the conduction state of the second inlet 14.

[0080] refer to Figure 5 When the drive fan 7 is driven to rotate and its air outlet is connected to the second inlet 14, both the first opening and closing structure 15 and the second opening and closing structure 16 are opened. The first air inlet 101 is connected to the air inlet passage 201. The drive fan 7 discharges the airflow through the second inlet 14 and merges with the airflow from the second air outlet 12 of the second air outlet system 2 before discharging the airflow from the annular air outlet structure 8. The arrows in the figure indicate the direction of airflow.

[0081] refer to Figure 6 When the drive fan 7 is driven to rotate and its air outlet faces the first air outlet 11, in this state, the first opening and closing structure 15 is closed while the second opening and closing structure 16 remains open. The first air intake 101 is connected to the second air outlet 14. Under the suction of the first air intake 101 of the drive fan 7, the air outlet part of the second air outlet 12 of the second air outlet system 2 enters the drive fan 7 through the second air outlet 14 and is discharged from the first air outlet system 1. The arrow in the figure indicates the direction of airflow.

[0082] refer to Figure 7 When the drive fan 7 is driven to rotate and its air outlet is directed toward the first air outlet 11, in this state, the first opening and closing structure 15 is opened while the second opening and closing structure 16 is kept closed. Then the first air intake 101 is only connected to the first air inlet 13, so that the first air intake 101 is connected to the air inlet passage 201. Air is discharged from the first air outlet 11 at the air outlet of the drive fan 7. The arrow in the figure indicates the direction of airflow.

[0083] Furthermore, the first opening and closing structure 15 is an electromagnetic control valve.

[0084] refer to Figure 1 , Figure 2 The second opening and closing structure 16 includes a switch plate 1601 and an opening and closing drive (not shown in the figure). The switch plate 1601 is movably disposed in the air outlet device. The opening and closing drive drives the switch plate 1601 to pivot or slide to open and close the second inlet 14, thereby controlling the conduction state of the second inlet 14.

[0085] The opening and closing drive component can be a motor or a power telescopic rod, and the power telescopic rod can be an electric, pneumatic, or hydraulic push rod.

[0086] In this embodiment, the switch plate 1601 is slidably disposed inside the air outlet device, and its movement is driven by the opening and closing drive component to control the conduction state of the second air outlet 14.

[0087] refer to Figure 1 , Figure 4 In detail, in this embodiment, the first air intake 101 is disposed on the upper side of the air outlet device, and the first air outlet 11 is configured to provide a blowing and releasing outlet for the first air outlet system 1.

[0088] In this embodiment, the air outlet device includes a body 17. The top of the body 17 is also provided with a lifting air outlet component 18 and a lifting drive component (not shown in the figure) corresponding to the first air outlet 11. The lifting air outlet component 18 is slidably disposed on the body 17 of the air outlet device. The lifting drive component is configured to drive the lifting air outlet component 18 to extend or retract relative to the body 17, so that when the lifting air outlet component 18 extends relative to the body 17, the body 17 forms the first air outlet 11 in a conducting state.

[0089] Thus, when the air outlet device is turned on, the lifting air outlet component 18 extends relative to the body 17, and the body 17 forms a first air outlet 11 in a conductive state, so that a first air outlet 11 for the first air outlet system 1 to outlet air is formed on the body 17.

[0090] refer to Figure 4 In this embodiment, the lifting air outlet assembly 18 includes a first plate 1801, a second plate 1802 and a third plate 1803. The second plate 1802 and the third plate 1803 are arranged in parallel and spaced apart. The first plate 1801 is disposed between the second plate 1802 and the third plate 1803 to form a first air outlet 11.

[0091] The body 17 is provided with a first slide groove 1701 and a second slide groove 1702. A second plate 1802 is slidably disposed in the first slide groove 1701, and a third plate 1803 is slidably disposed in the second slide groove 1702. When the lifting air outlet assembly 18 extends relative to the body 17, the first plate 1801 moves away from the body 17, and the first air outlet 11 is in a conducting state. When the lifting air outlet assembly 18 retracts relative to the body 17, the first plate 1801 moves closer to the body 17, and the first air outlet 11 is in a closed state.

[0092] Thus, since the second plate 1802 and the third plate 1803 are arranged in parallel and spaced apart, and the first plate 1801 is located between the second plate 1802 and the third plate 1803, the first plate 1801, the second plate 1802, and the third plate 1803 together enclose and form a frame-shaped first air outlet 11. Furthermore, since the body 17 is provided with a first sliding groove 1701 and a second sliding groove 1702, the second plate 1802 is slidably disposed within the first sliding groove 1701, and the third plate 1803 is slidably disposed within the second sliding groove 1702. When the lifting air outlet assembly 18 is relative to... When the body 17 extends, the first plate 1801, the second plate 1802, and the third plate 1803 all move away from the body 17. Then, the first air outlet 11 of the frame shape extends outward from the body 17 and connects with the outside of the air outlet device. When the air outlet device is closed, the lifting air outlet assembly 18 retracts into the body 17. Then, the first air outlet 11 of the frame shape retracts into the body 17 and is isolated from the outside atmosphere. That is, the lifting drive assembly controls the opening or closing of the first air outlet 11 by driving the lifting air outlet assembly 18 to extend or retract relative to the body 17.

[0093] The lifting drive assembly is one of the electric, pneumatic, or hydraulic telescopic rods arranged in the vertical direction, or it can be other linear drive devices in the prior art, such as gear and rack drive structures, screw and nut drive structures, etc.

[0094] In this embodiment, the first plate 1801 is further provided with a first air guide plate 18011 and a first air guide driving device (not shown in the figure). The first air guide plate 18011 is swayably disposed on the first plate 1801, and the first air guide driving device is configured to drive the first air guide plate 18011 to sway according to a preset wind direction adjustment.

[0095] In this way, the first air guide drive device can drive the first air guide plate 18011 to swing accordingly according to the user's preset wind direction, so that the present invention has the function of adjusting the wind direction up and down.

[0096] In this embodiment, the second plate 1802 is provided with a second air guide plate 18021 and a second air guide driving device (not shown in the figure). The second air guide plate 18021 is swayably disposed on the second plate 1802, and the second air guide driving device is configured to drive the second air guide plate 18021 to sway according to a preset wind direction adjustment.

[0097] In this way, the second air guide drive device can drive the second air guide plate 18021 to swing left and right accordingly according to the user's preset wind direction, so that the present invention has the function of adjusting the wind direction up and down and left and right.

[0098] In this embodiment, the third plate 1803 is provided with a third air guide plate 18031 and a third air guide driving device (not shown in the figure). The third air guide plate 18031 is swayably disposed on the third plate 1803, and the third air guide driving device is configured to drive the third air guide plate 18031 to sway according to a preset wind direction adjustment.

[0099] In this way, the third air guide drive device can drive the third air guide plate 18031 to swing accordingly according to the user's preset wind direction, and coordinate with the second air guide plate 18021 to swing in the same direction, thus enhancing the function of wind direction adjustment.

[0100] Preferably, the first, second and third air guide drive devices are all servo motors, or other existing devices capable of driving the plate to rotate.

[0101] In this embodiment, the first plate 1801, the first air guide plate 18011, the second plate 1802, and the second air guide plate 18021 are all provided with a heat insulation layer.

[0102] In this way, by applying insulation layers of equal size (not shown in the figure) to the first plate 1801, the first air guide plate 18011, the second plate 1802, and the second air guide plate 18021, the energy of the cold / warm air is prevented from dissipating through the first plate 1801, the first air guide plate 18011, the second plate 1802, and the second air guide plate 18021, and the energy of the cold / warm air is retained as much as possible.

[0103] refer to Figure 4 In this embodiment, the air outlet device includes a rear shell 19, a front shell 20, a base 21, and a mounting base 22. The rear shell 19, the front shell 20, and the base 21 together enclose the body 17 of the air outlet device. The mounting base 22 divides the interior of the body 17 into a first mounting cavity 9 and a second mounting cavity 10. A first air outlet 13 is formed on the mounting base 22, and a second air outlet 14 is formed on the front shell 20.

[0104] Among them, the front shell 20 and the baffle 802 of the annular air outlet structure 8 are integrally formed.

[0105] In this embodiment, the second air outlet 12 is located on the front shell 20.

[0106] In one possible implementation, a movable cover (not shown in the figure) can also be provided to control the opening and closing state of the second air outlet 12.

[0107] The movable cover can be pivotally connected to the body 1. When the movable cover closes the second air outlet, the air outlet of the second air outlet system 2 stops from the second air outlet 12. Then, the fan 7 can be driven so that its air outlet is facing the first air outlet 11. The first opening and closing structure 15 is opened while the second opening and closing structure 16 is kept closed. Then the first air intake 101 is only connected to the first air inlet 13, so that the first air intake 101 is connected to the air inlet passage 201. All the airflow of the second air outlet system 2 is drawn in by the driving fan 7 through the first air inlet 13, and finally only the air outlet system is discharged.

[0108] Alternatively, if the baffle 802 is made into a telescopic plate, the baffle 802 can be extended to close the gap between it and the outer frame 801, that is, to close the annular air outlet structure 8, so that the air of the second air outlet system stays in the air outlet device, and then the drive fan 7 is driven to rotate, so that its air outlet end faces the first air outlet 11, closing the first opening and closing structure 15 while keeping the second opening and closing structure 16 open. Then the first air intake 101 is connected to the second air inlet 14. Under the suction drive of the first air intake 101 of the drive fan 7, all the airflow of the second air outlet system 2 enters the drive fan 7 through the second air inlet 14 and is discharged from the first air outlet system 1.

[0109] In other possible implementations, the front shell 20 and the annular air outlet structure 8 can be formed independently and then reassembled.

[0110] In this embodiment, the specific type of the exhaust fan 5 is a cross-flow fan. In other embodiments, the specific type of the exhaust fan 5 can be adjusted according to the specific circumstances.

[0111] The specific type of the driving fan 7 is a turbine fan. In other embodiments, the specific type of the outlet fan 5 can be adjusted according to the specific circumstances.

[0112] Example 2

[0113] See Figure 8 This embodiment discloses an airflow regulation method, which uses any of the air outlet devices in Embodiment 1. The airflow regulation method includes: step S1: operating the first air outlet system 1 and the second air outlet system 2; step S2: when it is necessary to increase the airflow delivery distance, at least a portion of the airflow in the air path of the second air outlet system 2 is drawn into the first air outlet system 1.

[0114] In this way, when a large-scale, long-distance airflow is needed for rapid temperature regulation, the first air outlet system 1 and the second air outlet system 2 are activated, allowing both systems to operate simultaneously. The first air outlet system 1 draws in a portion of the airflow from the air path of the second air outlet system 2 as its intake air, thereby increasing the output airflow of the first air outlet system 1 and decreasing the output airflow of the second air outlet system 2. Since the first air outlet system 1 and the second air outlet system 2 are arranged vertically on the air outlet equipment, the high-speed, high-volume temperature-regulating airflow emitted by the first air outlet system 1, after being blown out from the upper side of the air outlet equipment, can reach locations farther away from the air outlet equipment, achieving a wider range of temperature regulation. Meanwhile, because the second air outlet system 2 is located on the lower side of the air outlet equipment, its low-speed, low-volume temperature-regulating airflow can be directed towards objects closer to the air outlet equipment (such as sofa sets in the living room or dining room). (e.g., the dining table), and because the high-speed, high-volume temperature-regulating airflow emitted by the first air outlet system 1 blows out from the upper part of the air outlet device, it avoids the temperature-regulating objects that are close to the air outlet device, thus achieving uniform temperature regulation for objects near or far from the air outlet device. At the same time, it reduces the direct blowing sensation and improves the user's comfort in receiving the airflow from the air outlet device. Moreover, in this way, after the high-speed, high-volume temperature-regulating airflow emitted by the first air outlet system 1 regulates the temperature of the area far from the air outlet device, the temperature regulation effect spreads from the area far from the air outlet device to the area near the air outlet device, achieving temperature regulation from far to near. This avoids or slows down the dissipation of the temperature regulation energy blown by the second air outlet system 2 from the area near the air outlet device to the area far from the air outlet device, thus maintaining the temperature regulation effect in the area near the air outlet device. In other words, it achieves the function of regional temperature control and has a better overall temperature regulation effect.

[0115] Preferably, step S2 includes a first operating mode 2.1, which is:

[0116] The first air outlet system 1 draws in airflow that has not undergone heat exchange treatment by the second air outlet system 2.

[0117] In this way, due to the adoption of this working mode, the first air outlet system 1 draws in air that has not undergone heat exchange treatment by the second air outlet system 2. Therefore, the temperature control energy of the second air outlet system 2 is not reduced. That is, without changing the temperature control energy of the second air outlet system 2, the air volume of the second air outlet system 2 is reduced. This results in the low wind speed and low air volume temperature-regulating airflow emitted by the second air outlet system 2 being blown out from the bottom of the air outlet equipment and directed towards the temperature-regulating object close to the air outlet equipment (such as the sofa set in the living room or the dining table in the dining room), which has the characteristic of low blowing sensation.

[0118] Preferably, the first operating mode 2.1 includes:

[0119] Mode 2.1(a): The first air outlet system 1 draws airflow from the air inlet 201 of the second air outlet system 2; and

[0120] Mode 2.1(b): The first air outlet system 1 draws airflow from the air outlet path 202 of the second air outlet system 2.

[0121] Thus, in mode 2.1(a), since the air intake path 201 of the second air outlet system 2 is not driven by acceleration, the airflow has the characteristics of low initial velocity and large volume. Therefore, in this mode, the first air outlet system 1 obtains high wind speed and high air flow by increasing the air intake volume.

[0122] In mode 2.1(b), the first air outlet system 1 draws in the airflow that has not been heat-treated from the air outlet path 202 of the second air outlet system 2. At that time, the airflow drawn in has a high speed at the outlet position. Therefore, it can provide high-speed airflow to the second air outlet system 2, so as to achieve higher speed and airflow of the second air outlet system 2.

[0123] Preferably, in the first air outlet system 1 and the second air outlet system 2, at least the second air outlet system 2 is capable of heat exchange treatment of the airflow. Step S2 includes a second operating mode 2.2, which is:

[0124] The first air outlet system 1 draws in the heat-treated airflow from the air outlet path 202 of the second air outlet system 2.

[0125] Thus, since the airflow from the outlet air passage 202 of the second air outlet system 2 is the airflow after being accelerated and heat-exchanged by the second air outlet system 2, the airflow has both temperature control energy and a high blowing speed. When the air outlet device is in the second working mode 2.2, the first air outlet system 1 draws in the airflow from the outlet air passage 202 of the second air outlet system 2. After the first air outlet system 1 draws in the airflow with high initial wind speed and temperature control energy, and after being accelerated and heat-exchanged again by the first air outlet system 1, compared with the first working mode, the first air outlet system 1 emits airflow with stronger temperature control function and stronger blowing speed, so that the first air outlet system 1 obtains stronger temperature control adjustment capability and a larger temperature control adjustment range.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
