Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to an air outlet panel of a duct machine and an air duct machine. Background Art

[0002] With the development of the times and the advancement of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners. No wind feeling and comfortable wind are two problems currently faced. No wind feeling means that when the air conditioner is running, the hot and cold winds avoid the human body. When cooling, the cold wind blows toward the ceiling. Due to the high density of the cold wind, it forms convection with the indoor air, and the cold wind avoids the human body and accelerates the reduction of the indoor temperature; when heating, the hot wind blows toward the floor. Due to the low density of the hot wind, it can form convection with the upper air, and the hot wind avoids the human body and accelerates the increase of the indoor temperature. Since the wind of ordinary air conditioners is blown out directly after passing through the heat exchanger, the temperature of the wind directly blowing to the human body is too low or too high, which is easy to cause discomfort. Therefore, comfortable wind means that even if the air conditioner blows directly to the human body, it will not make people feel uncomfortable without affecting the room temperature adjustment speed, avoiding discomfort caused by excessively cold or overheated wind.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: it is impossible to have both a windless and comfortable wind air supply mode. Summary of the invention

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The disclosed embodiments provide an air outlet panel of a duct machine and an air duct machine to solve the problem that an air supply mode cannot have both a windless feeling and a comfortable wind feeling.

[0006] In some embodiments, the air outlet panel of the duct machine includes: an air guide plate, which includes a main body plate provided with a hollow portion; an air guide swing blade assembly, which includes a rotating shaft and a swing blade arranged on the rotating shaft, and the swing blade is arranged in the hollow portion of the main body plate; and a first driving member, which is used to drive the swing blade to rotate relative to the main body plate, wherein the main body plate is provided with a groove, and the first driving member is arranged in the groove.

[0007] In some embodiments, the duct air conditioner includes the duct air conditioner air outlet panel provided in the aforementioned embodiments.

[0008] The duct air outlet panel and duct air conditioner provided in the embodiments of the present disclosure can achieve the following technical effects:

[0009] During refrigeration, the first driving member drives the swing blade to rotate, increasing the upward air supply angle so that the cold air is blown out in a higher and farther direction. During heating, the first driving member drives the swing blade to increase the downward air supply angle so that the hot air is blown out in a lower direction, realizing a draft-free air supply mode. Additionally, during refrigeration or heating air supply, the first driving member drives the swing blade to rotate relative to the main body plate, and the high-speed cold air or hot air blown out forms a negative pressure near the hollow part, attracting room temperature air to pass through the hollow part and mix with the hot air or cold air to form comfortable air with a suitable temperature, realizing a comfortable air supply mode, thereby improving the user's comfort. Furthermore, the first driving member is arranged in the groove of the main body plate, which helps to save the internal space of the air outlet panel of the air duct machine.

[0028] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0029] As Figures 1 to 7 shown, the embodiments of the present disclosure provide an air outlet panel for an air duct machine, including a guide vane. The guide vane includes a main body plate 10, a guide vane assembly, and a first driving member. The main body plate 10 is provided with a hollowed-out portion 101; the guide vane assembly includes a rotating shaft 30 and a vane 20 arranged on the rotating shaft. The vane 20 is arranged in the hollowed-out portion 101 of the main body plate 10; and a first driving member for driving the vane to rotate relative to the main body plate. Among them, the main body plate 10 is provided with a groove 102, and the first driving member is arranged in the groove 102.

[0030] With the above embodiments, during refrigeration, the first driving member drives the vane to rotate, increasing the upward air supply angle, so that the cold air is blown out in a higher and farther direction. During heating, the first driving member drives the vane, increasing the downward air supply angle, so that the hot air is blown out in a lower direction, realizing a windless air supply mode. In addition, during refrigeration or heating air supply, the first driving member drives the vane to rotate relative to the main body plate, and the high-speed cold air or hot air blown out forms a negative pressure near the hollowed-out portion, attracting normal-temperature air to pass through the hollowed-out portion and mix with the hot air or cold air, forming a comfortable wind with a suitable temperature, realizing a comfortable wind air supply mode, thereby improving the comfort of users. In addition, the first driving member is arranged in the groove of the main body plate, which helps to save the internal space of the air outlet panel of the air duct machine.

[0031] Optionally, the main body plate 10 is provided with a plurality of hollowed-out portions 101 arranged at equal intervals. As Figure 2 shown. In this way, when the cold air or hot air forms a negative pressure in the hollowed-out portion 101, the main body plate 10 is uniformly stressed, and the normal-temperature air passes through the hollowed-out portion 101 and mixes evenly with the hot air or cold air, ensuring that the air flow blowing towards the human body is a comfortable wind with a suitable temperature.

[0032] Optionally, some or all of the axes of the plurality of hollow portions 101 are parallel. When some of the axes of the plurality of hollow portions 101 are parallel, that is, there are some hollow portions 101 whose axes are not parallel. For example, the axis of the hollow portion 101 in the middle of the main body plate 10 is parallel to the cross-section of the main body plate 10; the axes of the hollow portions 101 on both sides of the main body plate 10 are arranged at a certain angle with the cross-section of the main body plate 10, that is, not parallel to the axis of the hollow portion 101 in the middle of the main body plate 10, and the axes of the hollow portions 101 at both ends of the main body plate 10 are inclined outward from the middle of the main body plate 10. In this way, it helps to cooperate with the swing blades to guide the air flow output and expand the air supply range of the air flow. The "axis" in the embodiments of the present disclosure can be understood as the symmetric dividing line of the hollow portion. As Figure 2 shown, the main body plate 10 is provided with 6 hollow portions, among which, the two middle hollow portions are parallel to the cross-section of the main body plate 10, the two left hollow portions are inclined to the left, and the two right hollow portions are inclined to the right.

[0033] Optionally, the rotating shaft 30 is perpendicularly arranged with respect to the cross-section of the main body plate 10. In this way, it can better realize the rotation of the rotating shaft driving the swing blades and adjust the blowing angle of the air from the hollow portion 101.

[0034] Optionally, the swing blades 20 are attached to the inner surface of the main body plate 10, or attached to the outer surface of the main body plate 10, or located inside the hollow portion 101 and attached to the inner side wall of the hollow portion 101. When the swing blades are attached to the inner surface or the outer surface of the main body plate, the area of the windward surface of the swing blades is larger than the area of the hollow portion. In this way, the blowing angle of the air from the hollow portion can be adjusted. In practical applications, users can choose to use according to the actual situation. Optionally, the number of the swing blades 20 is multiple. Optionally, the swing blades are tongue-shaped, as Figure 3 shown.

[0035] Optionally, the swing blades 20 rotate clockwise upward with respect to the main body plate 10 within an angle range of 0 - 60°, and rotate counterclockwise downward within an angle range of 0 - 60°. In this way, it can better realize the no-wind-sensation air supply and improve the user's comfort in using the air.

[0036] Optionally, the swing blades 20 fit with the hollow portion 101. In this case, that is, the swing blades are located inside the hollow portion and the side walls of the swing blades are attached to the inner side walls of the hollow portion. On the one hand, it is beautiful and tidy. On the other hand, in the production and manufacturing process, the hollow portions of the main body plate can be realized by stamping technology, and the stamped materials can be used as the swing blades, which helps to save materials and reduce production costs. In addition, when the swing blades fit with the hollow portion, it helps to reduce the abnormal noise generated when the air flow passes through the swing blades and the hollow portion.

[0037] Optionally, as Figure 3As shown in the figure, the swinging blades 20 include: a first swinging blade group 201 disposed at the first end of the rotating shaft 30; a second swinging blade group 202 disposed at the second end of the rotating shaft 30; and a third swinging blade group 203 disposed in the middle of the rotating shaft 30. Among them, the swinging blades in the first swinging blade group 201 and the swinging blades in the second swinging blade group 202 are inclined with respect to the swinging blades in the third swinging blade group 203. In this way, the airflow is guided to output through the swinging blades of the first swinging blade group 201 and the second swinging blade group 202. By tilting the swinging blades, it helps to expand the air supply range of the airflow.

[0038] Here, "the swinging blades in the first swinging blade group 201 and the swinging blades in the second swinging blade group 202 are inclined with respect to the swinging blades in the third swinging blade group 203" can be understood as: the first swinging blade group 201, the second swinging blade group 202, and the third swinging blade group 203 are all located in the same plane. The axis of the swinging blade in the first swinging blade group 201 forms a certain angle with the axis of the swinging blade in the third swinging blade group 203. The swinging blades in the first swinging blade group 201 are inclined from the third swinging blade group 203 towards the end of the main body plate 10, as Figure 3 shown, the swinging blades in the first swinging blade group tilt to the left; similarly, the axis of the swinging blade in the second swinging blade group 202 forms a certain angle with the axis of the swinging blade in the third swinging blade group 203. The swinging blades in the second swinging blade group 202 are inclined from the third swinging blade group 203 towards the other end of the main body plate, as Figure 3 shown, the swinging blades in the second swinging blade group tilt to the right. Similarly, the "axis" in the embodiments of the present disclosure can be understood as the symmetric dividing line of the swinging blade.

[0039] Optionally, the first swinging blade group 201 and the second swinging blade group 202 are symmetrically arranged. In this way, it helps to expand the air supply range of the airflow. For example, in practical applications, the swinging blades of the first swinging blade group 201 supply air to the left area of the main body plate 10, the swinging blades of the second swinging blade group 202 supply air to the right area of the main body plate 10, and the swinging blades of the third swinging blade group 203 supply air forward along the air supply direction of the main body plate 10 to the main body plate 10.

[0040] Optionally, the first swinging blade group 201 includes one or more first swinging blades. Among them, the axes of the multiple first swinging blades in the first swinging blade group 201 are parallel; the second swinging blade group 202 includes one or more second swinging blades. Among them, the axes of the multiple second swinging blades in the second swinging blade group 202 are parallel; the third swinging blade group 203 includes one or more third swinging blades. Among them, the axes of the multiple third swinging blades in the third swinging blade group 203 are parallel. In this way, it helps to supply air evenly and prevent the airflow from becoming disordered.

[0041] Optionally, as Figure 3As shown, the air guiding swing blade assembly further includes: a rotating shaft fixing member 70 for fixing the swing blade 20 to the rotating shaft 30. In this way, the swing blade is fixedly connected to the rotating shaft through the fixing member, enabling the rotating shaft to drive the swing blade to rotate, thereby adjusting the blowing angle of the air from the hollow portion 101.

[0042] Optionally, the swing blade 20 is connected to one or more rotating shaft fixing members 70. Among them, when the swing blade is connected to multiple rotating shaft fixing members 70, the multiple rotating shaft fixing members 70 are evenly spaced and distributed on the swing blade. In this way, it helps the swing blade to be evenly stressed and swing more smoothly. In addition, when one of the rotating shaft fixing members 70 fails, the swing blade is not affected and can still be used. As Figure 3 shown, a rotating shaft fixing member is provided at each end of each swing blade.

[0043] Optionally, the rotating shaft fixing member 70 is provided on the windward surface of the swing blade 20, and the rotating shaft 30 passes through and is fixedly connected to the rotating shaft fixing member 70. In this way, the multiple rotating shaft fixing members 70 are coaxially arranged, which helps to ensure that the installation positions of the multiple swing blades are consistent.

[0044] Optionally, one end of the rotating shaft fixing member 70 is connected to the swing blade 20, and the other end is connected to the rotating shaft 30. In this way, when one of the rotating shaft fixing members 70 fails, it helps the user to replace and repair the rotating shaft fixing member 70.

[0045] Optionally, the main body plate includes an inner surface and an outer surface. Among them, the groove is provided on the inner surface of the main body plate. The inner surface of the main body plate is the windward surface. The outer surface of the main body plate is the leeward surface, which can be understood as the side facing the user. In this way, the groove is provided on the inner surface of the main body plate, and the first driving member is also located on the inner surface of the main body plate, making the appearance neat.

[0046] Optionally, a part of the first driving member is embedded in the groove. In this way, it is convenient for the output end of the first driving member to be connected to the rotating shaft. Optionally, the bottom area of the groove is larger than the bottom area of the first driving member. In this way, it is beneficial for the first driving member to adjust the installation position according to actual needs. In addition, it is convenient for the disassembly and assembly of the first driving member. Optionally, the first driving member is detachably connected to the groove of the main body plate. For example, the first driving member is snap-connected to the main body plate, the first driving member is connected to the main body plate by screws or bolts, and the first driving member is bonded to the groove of the main body plate.

[0047] Optionally, in combination with Figure 1 and Figure 5As shown, the first driving member is a motor 40. The motor 40 includes a motor output shaft (not shown in the figure) and a sleeve 401. The motor output shaft is in interference fit with one end of the sleeve, and the rotating shaft 30 of the air guiding swing blade assembly is in interference fit with the other end of the sleeve 401. In this way, the motor output shaft drives the sleeve to rotate, and the sleeve drives the rotating shaft to rotate. The interference fit between the motor output shaft and the sleeve and the interference fit between the sleeve and the rotating shaft are beneficial to improving the stability during the rotation of the rotating shaft. In addition, it is not only beneficial to the synchronous rotation of the motor output shaft and the rotating shaft, but also beneficial to improving the transmission stability between the first driving member and the rotating shaft.

[0048] For the convenience of distinction and description, it is defined that "the end of the sleeve connected to the motor output shaft" is the first end, and "the end of the sleeve connected to the rotating shaft" is the second end.

[0049] Optionally, the first end of the sleeve is sleeved on the output end of the motor output shaft. Optionally, a first keyway is provided at the output end of the motor output shaft, and a first clamping groove adapted to the first keyway is provided on the inner side wall of the first end of the sleeve. The motor output shaft and the sleeve are assembled and fixed by a key, which is beneficial to improving stability and preventing the sleeve and the motor output shaft from slipping and loosening; at the same time, it is beneficial to transmit torque.

[0050] Optionally, the first driving member further includes a first positioning member (not shown in the figure). A first through hole is provided at the first end of the sleeve, and a first through hole is provided at the output end of the motor output shaft. The first positioning member penetrates through the first through hole and the first through hole. Among them, the axis of the first through hole is perpendicular to the axis of the sleeve. The first end of the sleeve is sleeved on the output end of the motor output shaft. The first through hole is aligned with the first through hole. It can be understood that the axis of the first through hole and the axis of the first through hole are on the same straight line. The length of the first positioning member is greater than the outer diameter of the sleeve. Both ends of the first positioning member are fixed by split pins. In this way, it is prevented that the first positioning member slides out of the first through hole and the first through hole, improving the connection stability between the sleeve and the motor output shaft, and being beneficial to ensuring the synchronous rotation of the sleeve and the motor output shaft.

[0051] Optionally, the second end of the sleeve is sleeved on the torque input end of the rotating shaft. Optionally, a second keyway is provided at the torque input end of the rotating shaft, and a second clamping groove adapted to the second keyway is provided on the inner side wall of the second end of the sleeve. The rotating shaft and the sleeve are assembled and fixed by a key, which is beneficial to improving stability and preventing the sleeve and the rotating shaft from slipping and loosening; at the same time, it is beneficial to transmit torque.

[0052] Optionally, the first driving member further includes a second positioning member (not shown in the figure). The second end of the sleeve is provided with a second through hole, and the torque input end of the rotating shaft is provided with a second through hole. The second positioning member passes through the second through hole and the second through hole. Among them, the axis of the second through hole is perpendicular to the axis of the sleeve. The second end of the sleeve is sleeved on the torque input end of the rotating shaft. The second through hole is aligned with the second through hole. It can be understood that the axis of the second through hole and the axis of the second through hole are located on the same straight line. The length of the second positioning member is greater than the outer diameter of the sleeve. Both ends of the second positioning member are fixed by split pins. In this way, the second positioning member is prevented from sliding out of the second through hole and the second through hole, improving the connection stability between the sleeve and the rotating shaft, and facilitating ensuring the synchronous rotation of the sleeve and the rotating shaft.

[0053] In practical applications, when the motor rotates forward or backward, the output shaft of the motor drives the rotating shaft to rotate forward or backward through the sleeve, thereby driving the swing blade to rotate upward or downward.

[0054] Optionally, as Figure 4 shown, the swing blade 20 is provided with a plurality of micropores 204. When the main body plate is completely closed, the air flow blows out through the micropores on the swing blade, with a low wind speed, realizing a gentle wind feeling and improving the comfort of the user. Optionally, the plurality of micropores are evenly spaced on the swing blade. Optionally, the plurality of micropores are arranged in part or all of the area of the swing blade.

[0055] Optionally, the axis of the micropore is perpendicular to the windward surface of the swing blade. In this way, when the main body plate and the swing blade are completely closed, the air flow blows out of the swing blade vertically through the micropores, and the air flow direction is higher than the user, acting on the indoor air to achieve windless air supply. Optionally, the micropores are inclined. When the main body plate and the swing blade are completely closed, the axis of the micropore is inclined downward from the air inlet to the air outlet. In this way, when the main body plate or the swing blade rotates at a certain angle, the air flow blows out along the inclined micropores, expanding the air supply range of the air deflector.

[0056] In practical applications, when the main body plate is completely closed, the swing blade can also be opened, and the air supply volume can be controlled by controlling the rotation angle of the swing blade. At the same time, the swing blade cooperates with the micropores to realize the gentle wind feeling air supply mode.

[0057] Optionally, the air deflector further includes: a second driving member for driving the main body plate to rotate. In this way, by driving the main body plate 10 to rotate through the second driving member, the air supply area of the main body plate 10 is adjusted to achieve large-area air supply and quickly cool or heat the room.

[0058] In practical applications, in combination with Figure 6As shown, when the second driving member drives the main body plate 10 to be in a closed and non-rotating state, the first driving member can drive the swing blade 20 to rotate towards the leeward side of the main body plate 10, realizing small-area air supply, which helps to reduce the discomfort caused by the large-area output of air flow to the human body. When the swing blade 20 rotates to form a certain angle with the windward side of the main body plate 10, driving the main body plate 10 to rotate through the second driving member helps the normal-temperature air to be fully mixed with the cold or hot air in the hollow part 101, and without affecting the refrigeration / heating effect, keeps the output air flow at a more appropriate temperature, making the human body feel comfortable.

[0059] In practical applications, during refrigeration, the second driving member drives the main body plate 10 to open, and then the first driving member drives the swing blade 20 to rotate upward to the maximum angle. At this time, the cold air blows out from the hollow part 101 along the swing blade to a higher and farther direction, realizing a windless air supply mode. Combined with Figure 7 As shown, during heating, the second driving member drives the main body plate 10 to open to the maximum angle, and then the first driving member drives the swing blade 20 to rotate downward to the maximum angle. At this time, the hot air blows out from the hollow part 101 along the swing blade 20 to a lower direction, realizing a windless air supply mode.

[0060] In addition, during refrigeration or heating, both the main body plate and the swing blade rotate by a certain angle, and a part of the air flow blows out along the main body plate, and the other part blows out along the swing blade and the micropores, forming two different air flows, expanding the air supply range and making the indoor temperature change more uniform.

[0061] Optionally, as Figure 1 shown, the air deflector further includes: a rotating shaft support member 80 for passing through the rotating shaft 30. In this way, the rotating shaft support member 80 supports the rotating shaft, preventing the rotating shaft 30 from bending. Optionally, the rotating shaft support member 80 can be arranged in the middle of the rotating shaft 30, or arranged at the end of the rotating shaft 30 and opposite to the first driving member. In this way, a better supporting effect can be achieved.

[0062] Optionally, the rotating shaft support member 80 is one or more. When multiple rotating shaft support members 80 are adopted, the multiple rotating shaft support members 80 are arranged at intervals on the rotating shaft. In this way, it helps to prevent the rotating shaft from bending due to excessive length and ensures the straightness of the rotating shaft.

[0063] Optionally, the rotating shaft support member 80 can be a bearing seat. Among them, the base of the bearing seat is detachably connected to the windward side of the main body plate 10, the rotating shaft 30 passes through the bearing seat, and rotates relative to the bearing seat under the drive of the first driving member.

[0064] Optionally, combined with Figure 6 and Figure 7As shown, the air outlet panel of the air duct machine further includes an air outlet panel frame body 60, and two or more air guide plates are arranged inside the air outlet panel frame body 60. In this way, by guiding the air flow at different angles through two or more air guide plates, it is not only beneficial to expand the air supply range, but also can quickly cool or heat the indoor temperature and make the temperature change more uniform, improving the comfort of users.

[0065] Optionally, the second driving member is arranged on the inner surface of the air outlet panel. In this way, the overall appearance of the air outlet panel of the air duct machine can be made beautiful. Optionally, the second driving member includes a main board motor and a swing arm 50 connected to the main board motor. The swing arm 50 is arranged on the inner surface of the main board 10. The swing arm 50 is relatively stationary with respect to the main board 10, and the main board motor drives the swing arm to rotate, thereby realizing the rotation of the main board, that is, the air guide plate rotates upward or downward relative to the air outlet panel.

[0066] For the convenience of distinction and description, when there are two air guide plates on the air outlet panel, the two air guide plates are defined as the first air guide plate and the second air guide plate respectively. When the first air guide plate and the second air guide plate are all opened, the air flow can flow through the first air guide plate and the second air guide plate in sequence or flow through the first air guide plate and the second air guide plate respectively.

[0067] Optionally, two or more air guide plates are arranged side by side. In this way, it is not only beneficial to control the air supply area, but also can guide the air flow through multiple air guide plates, thereby controlling the air supply range. Optionally, the air outlet directions of two or more air guide plates are partially or completely the same. In this way, it is beneficial to expand the air supply range of the air flow.

[0068] Combined Figure 6 and Figure 7 As shown, taking two air guide plates as an example, the two air guide plates are arranged side by side up and down. The two air guide plates are arranged in the same plane. In practical applications, optionally, the air outlet directions of the first air guide plate and the second air guide plate are the same. In this way, the air supply area can be adjusted by rotating the rotation angle of the first air guide plate or the second air guide plate. Optionally, the air outlet directions of the first air guide plate and the second air guide plate are opposite. That is, the first air guide plate rotates upward and the air outlet faces downward, and the second air guide plate rotates downward and the air outlet faces upward. In this way, when the first air guide plate and the second air guide plate are all opened, not only the air supply direction can be adjusted, but also the air supply area can be adjusted. Optionally, the swing blades are arranged in the same direction as the air guide plates.

[0069] Optionally, two or more air deflectors are arranged side by side left and right. In this way, any air deflector can be rotated according to the actual situation to achieve local area air supply. Optionally, the air outlet directions of two or more air deflectors are partially or completely the same. For example, in the case where two air deflectors are arranged side by side left and right, the air outlet direction of the first air deflector is set upward, and the air outlet direction of the second air deflector is set downward. In this way, it is beneficial to expand the air supply range. Optionally, the swing blades are arranged in the same direction as the air deflectors. In this way, it is beneficial to achieve a comfortable air supply mode or a no-wind-sensation air supply mode.

[0070] Optionally, the swing blades of two or more air deflectors are arranged in the same direction. In this way, it is beneficial to prevent the blown air flow from being disordered and further improves the user's comfort. Combining Figure 6 and Figure 7 As shown, taking two air deflectors as an example, the swing blades 20 of the two air deflectors are arranged in the same direction. In the case where the two air deflectors are arranged one above the other, a part of the air flow blows out along the swing blades of the first air deflector located above, and another part of the air flow blows out along the swing blades of the second air deflector located below. On the one hand, it expands the air supply range of the air flow, and on the other hand, the air flow blown out from the upper swing blades can act on the air flow blown out from the upper swing blades, so that the air flow blown out from the lower swing blades blows to a farther distance, expanding the air supply distance of the air flow.

[0071] Optionally, the swing blades of two or more air deflectors are partially arranged in the same direction. The swing blades of two or more air deflectors are partially arranged in the same direction. Taking two air deflectors as an example, it can be understood that the swing blades of the first air deflector are arranged in the opposite direction to the swing blades of the second air deflector. Among them, in the case where the two air deflectors are arranged one above the other, the first air deflector and the second air deflector are completely closed, a part of the air flow blows upward along the swing blades of the first air deflector located above, and another part of the air flow blows downward along the swing blades of the second air deflector located below, expanding the air supply range of the air flow.

[0072] In the case where the two air deflectors are arranged side by side left and right, a comfortable air or a no-wind-sensation air flow is provided to a local area through the swing blades arranged in the same direction. Different air supply modes for different areas are achieved through the swing blades arranged in the opposite direction. In this way, it is beneficial to meet the user's air use requirements and achieve the purpose of multiple air supply modes operating simultaneously.

[0074] The air duct machine air outlet panel is arranged at the air outlet of the indoor part of the air duct machine. In this way, first, a no-wind-sensation air supply mode can be obtained and comfortable air with a suitable temperature can be output. Second, during the refrigeration or heating process, the indoor temperature is more uniform. Finally, the structure of the air duct machine air outlet panel is simple, it occupies a small space, and the overall appearance is beautiful and tidy.
