Description

Technical Field

[0001] The utility model relates to an air conditioner, in particular to an air guide mechanism for an air outlet of an air duct unit and the air duct unit. Background Art

[0002] Duct air conditioners, or ducted air conditioners, generally deliver air to the room through air conditioner-connected ducts. Duct air conditioners are usually equipped with air guide plates at their air outlets, which swing to adjust the air outlet direction, so as to deliver hot or cold air into the room.

[0003] In the related art, the size of the air outlet speed in the traditional duct air conditioner air supply solution mainly depends on the fan inside the duct air conditioner, and an air outlet grille is set at the air outlet. Since the air outlet grille has limited adjustment of the air outlet angle, during the air supply process, the air outlet grille will also block the blown air flow to a certain extent, resulting in greater wind resistance of the duct air conditioner, causing the air supply speed of the duct air conditioner to be low and the air delivered to be easily dispersed, especially when heating, which is not conducive to raising the temperature, and will make users in the working environment of the duct air conditioner feel hot in the head and cold in the feet, resulting in a very poor user experience. Utility Model Content

[0004] One purpose of the utility model is to provide an air guide mechanism capable of increasing the air outlet speed.

[0005] A further object of the utility model is to provide an air guide plate with a flat outer side, which closes the air outlet and plays an aesthetic role when the air guide mechanism is in a closed state.

[0006] Another further object of the utility model is to provide an air guide plate with an arc-shaped inner side, which plays a role of guiding air downward in heating conditions.

[0007] In particular, the utility model provides an air guide mechanism for an air outlet of a duct machine, comprising a first air guide plate and a second air guide plate, wherein the first air guide plate and the second air guide plate are configured to rotate synchronously so that the air outlet air guide mechanism has a closed state in which the air outlet is closed and an air guiding state in which the air outlet is exposed, wherein the first air guide plate and the second air guide plate are arranged side by side with an interval, and the second plate surface of the first air guide plate is opposite to the first plate surface of the second air guide plate; the second plate surface of the first air guide plate has a first arc-shaped portion bent toward the second air guide plate at an end portion located on the air outlet side in the air guiding state; so that the interval between the first air guide plate and the second air guide plate is limited by the first arc-shaped portion and the first plate surface of the second air guide plate and shrinks along the air outlet direction.

[0008] Optionally, the air guide mechanism for the air outlet of the duct machine also includes: two connecting parts, which are respectively arranged at the two ends of the first air guide plate and the second air guide plate along the length direction, so that the first air guide plate and the second air guide plate are an integrated structure, and the connecting parts are respectively rotatably connected to the peripheral wall of the air outlet, so that the first air guide plate and the second air guide plate are configured to rotate synchronously.

[0009] Optionally, in a closed state, the first air guide plate is configured to close the outer side of the air outlet.

[0010] Optionally, the first plate surface of the first air guide plate is configured to be a flat plate that is adapted to the shape of the air outlet; and in a closed state, the first plate surface of the first air guide plate is substantially flush with the peripheral wall of the air outlet.

[0011] Optionally, the end of the first plate surface of the second air guide plate located on the air outlet side in the air guiding state has a second arc portion bent toward the first air guide plate; the arc radius of the second arc portion is smaller than that of the first arc portion.

[0012] Optionally, the end of the second plate surface of the first air guide plate located on the windward side in the wind guiding state has a third arc portion bent toward the second air guide plate, and the end of the first plate surface of the second air guide plate located on the windward side in the wind guiding state has a fourth arc portion in the same direction as the third arc portion; the radius of the third arc portion is greater than that of the fourth arc portion.

[0013] Optionally, the distance between the first arc-shaped portion and the second arc-shaped portion is smaller than the distance between the third arc-shaped portion and the fourth arc-shaped portion.

[0014] Optionally, the second plate surface of the second air guide plate is configured to be arc-shaped.

[0015] The utility model also provides a duct machine, comprising a housing and one or more air guide mechanisms. The housing is provided with an air outlet; the air guide mechanism is arranged at the air outlet; and the air guide mechanism is any of the above-mentioned air guide mechanisms.

[0016] Optionally, there are multiple air guiding mechanisms, which are arranged sequentially along the longitudinal direction of the air outlet.

[0017] The air guide mechanism of the air outlet of the duct machine of the utility model has a first air guide plate and a second air guide plate arranged at intervals, and a first arc-shaped portion is also provided at the end of the second plate surface of the first air guide plate located on the air outlet side. The interval between the first air guide plate and the second air guide plate is limited by the first arc-shaped portion and the first plate surface of the second air guide plate and shrinks along the air outlet direction. When supplying air, the airflow inside the duct machine can be blown downward at a higher wind speed, thereby increasing the air outlet speed, enhancing the user experience when using it, and improving the comfort of the room.

[0018] Furthermore, in the air guide mechanism of the air outlet of the duct machine of the utility model, the first plate surface of the first air guide plate is set to be a flat plate. When the air guide mechanism is in a closed state, the first plate surface of the first air guide plate is substantially flush with the outer casing of the duct machine, which not only closes the air outlet but also plays an aesthetic role.

[0019] In addition, a first arc-shaped portion facing the second air guide plate is also provided on the air outlet side of the second plate surface of the first air guide plate. Correspondingly, a second arc-shaped portion is provided on the air outlet side of the first plate surface of the second air guide plate. The contraction-shaped interval limited by the first arc-shaped portion and the second arc-shaped portion can play a role in guiding the wind downward. When the air guide mechanism is in the air guiding state, the bending directions of the first arc-shaped portion and the second arc-shaped portion are both toward the ground, which can increase the swing angle of the air supplied to the ground. When the air guide mechanism is in the heating condition, the hot air blown out by the air duct machine has a fast wind speed and is not easy to disperse. The hot air can reach the ground more easily and quickly, so that the temperature of the working environment of the air duct machine rises rapidly.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0033] Combine the following Figures 1 to 6 To describe the structure and working principle of the utility model.

[0034] Figure 1 is a perspective view of a duct machine 10 according to an embodiment of the utility model; Figure 2It is a front view of an air duct machine 10 according to an embodiment of the utility model; the air duct machine 10 of the embodiment of the utility model may generally include a housing 200 and an air guide mechanism 100. The housing 200 defines a containing space, and an airflow for adjusting the ambient temperature is formed inside the housing 200, such as cold air in the cooling mode or hot air in the heating mode. The air duct machine housing 200 is in the shape of a rectangular parallelepiped as a whole, and the front side of the housing 200 serves as an air outlet part. An air outlet 131 is provided on the front panel of the air outlet part, and an air guide mechanism 100 is provided at the air outlet 131, which is used to guide the airflow inside the air duct machine 10, compress it, and blow it into the working environment of the air duct machine 10.

[0035] The air guide mechanism 100 is arranged on the air outlet side. The air guide mechanism 100 includes a first air guide plate 110 and a second air guide plate 120, which are arranged side by side and spaced apart, and the second plate surface 112 of the first air guide plate 110 is opposite to the first surface of the second air guide plate 120. The first air guide plate 110 and the second air guide plate 120 can be controlled to rotate synchronously, and when rotating to a position opposite to the air outlet 131, the air outlet of the air outlet 131 is blown toward the working environment of the air duct machine 10 through the contracted gap formed by the first air guide plate 110 and the second air guide plate 120. In this way, the air outlet inside the air duct machine 10 is not blown directly to the outside of the air duct machine 10, but is first guided and contracted by the first air guide plate 110 and the second air guide plate 120 before being blown out to the working environment of the air duct machine 10.

[0036] In some embodiments, the duct machine 10 is in a rectangular shape as a whole, and a long air outlet 131 is opened on the front side of the duct machine 10. The air guide mechanism 100 is long and arranged inside the air outlet 131. It is rotatably connected to the outer shell 200 through the rotating shaft 132 on the connecting part 134. The shape of the air guide mechanism 100 is adapted to the opened air outlet 131. When the air guide mechanism 100 is in the air guiding state, the airflow inside the duct machine 10 can be deflected, contracted and accelerated by the air guide mechanism 100, so that the airflow inside the duct machine 10 can be efficiently and accurately blown to the working environment of the duct machine 10.

[0037] For example, Figure 1 , 2 As shown, in actual application, the air guide mechanism 100 can be arranged at the center of the front shell 200 of the air duct machine 10 according to actual use needs or the needs of the structure of the air duct machine 10, or it can be arranged as follows Figure 1 As shown, it is located close to one side.

[0038] Figure 3 yes Figure 2 A cross-sectional view of the air outlet portion of the duct unit 10 along the AA direction; Figure 3As shown, the first air guide plate 110 and the second air guide plate 120 of the air guide mechanism 100 are arranged at intervals, the second plate surface 112 of the first air guide plate 110 is opposite to the first plate surface 121 of the second air guide plate 120, and the first air guide plate 110 and the second air guide plate 120 can rotate synchronously. In the air guiding state, the second plate surface 112 of the first air guide plate 110 is provided with a first arc-shaped portion 113 facing the second air guide plate 120 at one end of the air outlet side, and the interval limited by the first arc-shaped portion 113 and the second air guide plate 120 shrinks along the air outlet direction, and the first air guide plate 110 and the second air guide plate 120 have two connecting portions 134 at both ends along the length direction, and the two connecting portions 134 are connected to the first air guide plate 110 and the second air guide plate 120 to form an integrated structure.

[0039] Furthermore, the first plate surface 121 of the second air guide plate 120 has a second arc portion 123 bent toward the first air guide plate 110 at the end portion on the air outlet side, and the arc radius of the second arc portion 123 is smaller than the first arc portion 113, and the first arc portion 113 and the second arc portion 123 are jointly defined to form a contracted interval. Figure 3 In the wind guiding state shown, the windward end of the second plate surface 112 of the first wind guide plate 110 has a third arc portion 114 bent toward the second wind shield, and the windward end of the first plate surface 121 of the second wind guide plate 120 has a fourth arc portion 124 in the same direction as the third arc portion 114. The third arc portion 114 and the fourth arc portion 124 have the same direction, so that the windward side can better receive the airflow flowing through the air outlet 131.

[0040] In addition, the radius of the third arc portion 114 is greater than that of the fourth arc portion 124, and the distance between the first arc portion 113 and the second arc portion 123 is less than the distance between the third arc portion 114 and the fourth arc portion 124, so that the interval between the first air guide plate 110 and the second air guide plate 120 is in a contracted shape. The air guide mechanism 100 provided in this way can make the airflow blown out by the air guide mechanism 100 less likely to disperse, and the wind speed is very fast, so that it is easy to achieve more accurate and faster air supply, so as to meet the needs of users and improve the user experience.

[0041] In some embodiments, the distance between the first arc portion 113 provided on the second plate surface 112 of the first air guide plate 110 and the second arc portion 123 provided on the first plate surface 121 of the second air guide plate 120 is smaller than the distance between the third arc portion 114 and the fourth arc portion 124. This arrangement can make the space limited by the first air guide plate 110 and the second air guide plate 120 shrink from the windward side to the wind outlet side, and the openings of the first air guide plate 110 and the second air guide plate 120 on the windward side of the air guide mechanism 100 are larger, so that the airflow inside the air duct machine 10 can enter the air guide mechanism 100 more, and after flowing through the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120, the airflow can be compressed and blown to the working environment of the air duct machine 10 on the wind outlet side through the guidance and contraction of the first arc portion 113 and the second air guide plate 120, so that the blown airflow is not easy to disperse, can be blown farther, and the wind speed is faster, so as to achieve the purpose of fast and accurate air supply.

[0042] It should be noted that the “windward side” and “windward side” should be understood as the following: when the airflow inside the duct unit 10 flows through the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120, the airflow passes through the wind guiding effect of the air guide mechanism 100 and flows from the air outlet 131 to the working environment of the duct unit 10, and the end that finally flows out is the windward side. Correspondingly, when the airflow flows inside the duct unit 10 and flows outward from the air outlet 131, the end that first contacts the airflow with the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120 is the windward side. Figure 3 As shown, in the wind guiding state, the first wind guide plate 110 and the second wind guide plate 120 are spaced apart, the second plate surface 112 of the first wind guide plate 110 and the first plate surface 121 of the second wind guide plate 120 are opposite, and the first arc portion 113 and the first plate surface 121 of the second wind guide plate 120 are limited to form a gap that shrinks along the wind outlet direction. Figure 3 In the process of airflow flowing outward from the inside of the duct machine 10, it first needs to flow in from the space restricted by the third arc portion 114 and the fourth arc portion 124. Therefore, the end where the third arc portion 114 and the fourth arc portion 124 are located is the windward side; after the airflow is deflected and contracted by the air guide mechanism 100 through which the airflow passes, it flows to the working environment outside the duct machine 10, and finally flows out of the duct machine 10 through the space restricted by the first arc portion 113 and the second arc portion 123. Therefore, the end where the first arc portion 113 and the second arc portion 123 are located is the outlet side. It can be understood that the opening restricted by the first air guide plate 110 and the second air guide plate 120, the side facing the outside of the duct machine 10 is the outlet side, and correspondingly, the side facing the inside of the duct machine 10 is the windward side.

[0043] Figure 4 yes Figure 3An enlarged view of the wind guide structure; in some embodiments, as Figure 4 As shown, the width of the first air guide plate 110 is different from that of the second air guide plate 120, that is, the second plate surface 112 of the first air guide plate 110 is different from the width of the first plate surface 121 of the second air guide plate 120, and the two air guide plates are arranged at a certain angle. The radii of the four arc portions arranged on the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120 are also different, which can together constitute the required air guide structure, so that the internal airflow of the duct machine 10 enters through the windward side of the air guide mechanism 100, and is blown out at a specified angle after being guided by the air guide mechanism 100.

[0044] In addition, the width of the first air guide plate 110 and the second air guide plate 120 can also be the same. At this time, the arc radius of the third arc portion 114 and the fourth arc portion 124 on the windward side can be adjusted according to the specific air outlet requirements to meet the requirement that the airflow in the duct machine 10 can smoothly flow into the air guide mechanism 100. On the basis of adjusting the radius of the third arc portion 114 and the fourth arc portion 124, the arc radius of the first arc portion 113 and the second arc portion 123 on the air outlet side should also be adjusted. By adjusting the arc radius and the arc length of the first arc portion 113 and the second arc portion 123, the airflow is blown to a specified direction through the air outlet side of the air guide mechanism 100 to meet the air supply requirements.

[0045] In some embodiments, Figure 4 As shown, the first arcuate portion 113 and the third arcuate portion 114 are provided at both ends of the second plate surface 112 of the first air guide plate 110, and the second plate surface 112 of the entire first air guide plate 110 is arc-shaped as a whole, that is, the plate surface portion between the first arcuate portion 113 and the third arcuate portion 114 is divided into a long arc, and correspondingly, the plate surface portion between the second arcuate portion 123 and the fourth arcuate portion 124 is also a long arc. The arcs of the two long arcuate plate surfaces are adapted to each other, and the whole is streamlined. In the wind-guiding state, the airflow inside the duct machine 10 enters the air-guiding mechanism 100 through the windward side, and the airflow can be smoothly delivered to the air outlet side of the air-guiding mechanism 100 through the space formed by the two long arcuate plate surfaces, thereby reducing the resistance during the wind-guiding process, and better guiding the airflow from the windward side of the air-guiding mechanism 100 to the air outlet side. In addition, in the wind guiding state, the first arc portion 113 disposed on the wind outlet side of the first wind guide plate 110 and the second arc portion 123 disposed on the wind outlet side of the second wind guide plate 120 are both bent toward the ground, which can increase the swing angle of the wind sent to the ground. When the wind guide mechanism 100 sends air, the air flow blown out by the air duct machine 10 has a high wind speed and is not easy to disperse, and can reach the ground more easily and quickly.

[0046] In addition, the long arc-shaped plate surface between the first arc-shaped portion 113 and the third arc-shaped portion 114 on the second plate surface 112 of the first air guide plate 110 can also be a straight plate surface, that is, the second plate surface 112 of the first air guide plate 110 is a plate surface with arcs on both sides and a straight line in the middle. Correspondingly, the long arc-shaped plate surface between the second arc-shaped portion 123 and the fourth arc-shaped portion 124 on the first plate surface 121 of the second air guide plate 120 is also a straight plate surface, and the first plate surface 121 of the second air guide plate 120 is also a plate surface with arcs on both sides and a straight line in the middle. During the air guiding process, the internal air flow of the duct machine 10 flows into the air guiding mechanism 100 through the space restricted by the third arc portion 114 and the fourth arc portion 124, flows through the space restricted by the straight plate surface between the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120, flows to the end where the first arc portion 113 and the third arc portion 114 are located, and is blown toward the working environment of the duct machine 10 through the gap between the first arc portion 113 and the third arc portion 114.

[0047] In some embodiments, the first air guide plate 110 and the second air guide plate 120 are not arranged in parallel, and the two air guide plates are arranged at an angle that shrinks from the windward side to the windward side. This allows the first arc portion 113 and the second arc portion 123 to better compress the passing airflow before sending the airflow to the working environment of the air duct machine 10. For example, Figure 4 As shown, the first air guide plate 110 and the second air guide plate 120 are arranged at a certain angle, so that the first air guide plate 110 and the second air guide plate 120 are in a state of contraction from the windward side to the air outlet side. After the airflow enters the air guide mechanism 100 on the windward side, it can be compressed on the air outlet side where the first arc portion 113 and the second arc portion 123 are located, so that the airflow blows to a farther place, thereby quickly achieving the purpose of changing the working environment temperature of the duct machine 10.

[0048] In addition, the first air guide plate 110 and the second air guide plate 120 can also be arranged relatively parallel. By changing the curvature of the third arc-shaped portion 114 and the fourth arc-shaped portion 124, the windward side of the air guide mechanism 100 can better receive the airflow inside the air duct machine 10 and enter the air guide mechanism 100. By changing the annular radius of the first arc-shaped portion 113 and the second arc-shaped portion 123, the airflow passing through the air outlet side of the air guide mechanism 100 can be blown to a designated position, and by changing the arc radius of the first arc-shaped portion 113 and the second arc-shaped portion 123, the airflow passing through the air outlet side can be compressed and blown to a farther distance.

[0049] Figure 5 is a schematic diagram of a closed state according to an embodiment of the utility model; in some embodiments, such as Figure 5As shown, when the air guide mechanism 100 is in a closed state, the first air guide plate 110 is located on the outside of the air outlet 131 relative to the second air guide plate 120, and the second air guide plate 120 is located on the inside of the air outlet 131 relative to the first air guide plate 110. The first plate surface 111 of the first air guide plate 110 is set to be a flat plate, and the shape of the flat plate is adapted to the air outlet 131. When the air guide mechanism 100 is in a closed state, the first plate surface 111 of the first air guide plate 110 and the peripheral wall of the air outlet 131 are substantially flush, and the air outlet 131 is closed so that the air outlet 131 no longer discharges air.

[0050] In some embodiments, Figure 5 As shown, when the air guide mechanism 100 needs to be closed, the air guide mechanism 100 is rotated to the position shown in the figure by rotating the rotating shaft 132. At this time, the air guide mechanism 100 closes the air outlet 131 opened on the housing 200, and the airflow cannot be blown out to the external environment through the air outlet 131. After the first air guide plate 110 and the second air guide plate 120 rotate synchronously, the first air guide plate 110 is located outside the air outlet 131 relative to the second air guide plate 120, and the second air guide plate 120 is located inside the air outlet 131 relative to the first air guide plate 110. The first plate surface 111 of the first air guide plate 110 is substantially flush with the surface of the air duct housing 200, so that the air guide mechanism 100 can completely close the air outlet 131, so that the airflow inside the air duct 10 no longer flows out, so as to achieve the purpose of closing the air outlet 131.

[0051] In addition, in order for the air guide mechanism 100 to smoothly reach the closed state, Figure 3 In the air supply state shown, the two ends of the first air guide plate 110 should be adaptively modified in shape so that when the air guide mechanism 100 is closed, the first air guide plate 110 will not contact the portion of the housing 200 above the air outlet 131 and cause the air guide mechanism 100 to get stuck. Correspondingly, a certain limit should be placed on the width of the second air guide plate 120 so that when the air guide mechanism 100 is closed, the second air guide plate 120 will not touch the portion of the housing 200 below the air outlet 131, so that the air guide mechanism 100 can be closed smoothly.

[0052] In some embodiments, a long strip air outlet 131 is opened on the air duct machine housing 200 to accommodate the air guide mechanism 100. The air duct machine 10 is provided with an air guide mechanism 100. The size and shape of the air guide mechanism 100 should be adapted to the long strip air outlet 131 so that the air guide mechanism 100 can be installed inside the air outlet 131. During the rotation process, the air guide mechanism 100 will not touch the upper and lower outer shell 200 parts of the air outlet 131. It should also be considered that when the air guide mechanism 100 is in a closed state, the air guide mechanism 100 can completely close the air outlet 131 so that the air flow inside the air duct machine 10 will not flow into the working environment of the air duct machine 10 when the air guide mechanism 100 is in a closed state.

[0053] For example, Figure 5 As shown, when the air guide mechanism 100 is in a closed state, after the air guide mechanism 100 is rotated, the first air guide plate 110 is located outside the air outlet 131 relative to the second air guide plate 120, and the first plate surface 111 of the first air guide plate 110 is substantially flush with the outer shell 200. At this time, the airflow inside the duct machine 10 will no longer flow outward through the air guide mechanism 100, and the duct machine 10 stops conveying airflow outward.

[0054] Figure 6 It is a three-dimensional diagram of an air guide mechanism 100 according to an embodiment of the utility model; the air guide mechanism 100 is rotatably connected to the housing 200 through the rotating shaft 132 on the connecting part 134, and the airflow inside the air duct machine 10 can be blown into the working environment of the air duct machine 10 through the air guide mechanism 100. In addition, the user can also adjust the air guide angle of the air guide structure according to the needs, so that the user's ambient temperature is adjusted to a satisfactory temperature. When not in use, the air guide mechanism 100 can also be rotated to a closed state, so that the first air guide plate 110 of the air guide mechanism 100 closes the air outlet 131. At this time, the first plate surface 111 of the first air guide plate 110 is located on the outside of the air outlet 131 relative to the second air guide plate 120. The first plate surface 111 of the first air guide plate 110 is a flat plate shape adapted to the long strip opening, so that the air guide mechanism 100 can completely close the air outlet 131 in the closed state, so that the airflow inside the air duct machine 10 cannot flow outward.

[0055] like Figure 6 As shown, in some embodiments, the two ends of the first air guide plate 110 and the second air guide plate 120 along the length direction are connected to form an integral structure through two connecting parts 134. On the side of the two connecting parts 134 close to the air duct machine housing 200, each has a rotating shaft 132 connected to the housing 200. The rotating shaft 132 can be driven by a motor or other similar driving mechanism, so that the connecting part 134 can rotate around the rotating shaft 132, so as to realize the synchronous rotation of the first air guide plate 110 and the second air guide plate 120. In actual use, the user can adjust the air outlet direction of the air guide mechanism 100, so that the air guide mechanism 100 can be rotated to different angles by rotating the rotating shaft 132, so as to meet the user's various requirements for air supply of the air duct machine 10.

[0056] Figure 7 is a schematic diagram of an asynchronous air outlet of an air guide mechanism 100 according to another embodiment of the utility model; in some embodiments, such as Figure 7As shown, during the use process, the lower wind guide mechanism 100 can be directed downward, and the upper wind guide mechanism 100 can be directed toward an angle away from the air duct machine 10. At this time, due to the preset angle of the lower wind guide mechanism 100, the opening limited by the first arc portion 113 and the second arc portion 123 is directed toward the ground below, so that the hot air flow in the air duct machine 10 can quickly reach the bottom surface. When supplying air, the airflow blown to the lower wind guide mechanism 100 is blown toward the working environment of the air duct machine 10 along the interval limited by the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120, so that the ambient temperature changes rapidly. The opening limited by the first arc portion 113 and the second arc portion 123 of the upper wind guide mechanism 100 is directed toward a point far away from the air duct machine 10, and the airflow flows through the interval limited by the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120, and blows toward a distant place, so as to meet the heat supply demand of a distant place quickly. For example, when the user is indoors, he needs to increase the indoor temperature and at the same time, he needs to have the hot air flow blown toward him in time. The above arrangement can be used. On the one hand, the lower air guide mechanism 100 delivers the hot air flow to the ground, while on the other hand, the upper air guide mechanism 100 blows the hot air flow toward the user. This allows the indoor temperature to rise rapidly and the hot air flow to blow toward the user rapidly.

[0057] Furthermore, in Figure 7 During the asynchronous air discharge process of the air duct machine 10 shown in the figure, the opening limited by the first arc portion 113 and the second arc portion 123 of the upper air guide mechanism 100 faces the front of the air duct machine 10. When the air duct machine 10 is running, the internal air flow of the air duct machine 10 flows into the air guide mechanism 100 through the opening limited by the third arc portion 114 and the fourth arc portion 124, passes through the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120 of the air guide mechanism 100, flows to the gap limited by the first arc portion 113 and the second arc portion 123, and is blown to the external environment after being compressed. The opening limited by the first arc portion 113 and the second arc portion 123 of the lower air guide mechanism 100 is different from that of the upper air guide mechanism 100. It is oriented toward the lower bottom surface. When the duct machine 10 is running, the air flow inside the duct machine 10 flows into the air guide mechanism 100 through the opening limited by the third arc portion 114 and the fourth arc portion 124, passes through the second plate surface 112 of the first air guide plate 110 and the first plate surface 121 of the second air guide plate 120 of the air guide mechanism 100, flows to the gap limited by the first arc portion 113 and the second arc portion 123, and is blown into the working environment of the duct machine 10 after being compressed.

[0058] In addition, a partition 133 can be horizontally arranged in the middle part of an air outlet 131 to divide the air outlet 131 into two parts, an upper part and an lower part. The upper and lower parts can each be provided with an air guide mechanism 100, so that the airflow inside the air duct machine 10 is blown to the external environment through the two air guide mechanisms 100 respectively.

[0059] Furthermore, in the embodiment where the air duct machine 10 is provided with two or more air guide mechanisms 100, a partition 133 may be provided between each two air guide mechanisms 100, and the partition 133 may be shaped as follows: Figure 3 , 5 As shown in Figures 7 and 8, the partition 133 is located between the two air guide mechanisms 100 to serve as a partition. When the air guide mechanism 100 is in a closed state, it can be substantially flush with the first plate surface 111 of the first air guide plate 110, and the inner side of the partition 133 should be set to a shape as shown in the figure, so that when the air guide mechanism 100 rotates from the air guiding state to the closed state or when the air guide mechanism 100 rotates from the closed state to the air guiding state, the various plate surfaces of the air guide mechanism 100 will not touch the partition 133 to hinder the rotation of the air guide mechanism 100.

[0060] For example, when the user needs to make the wind delivered by the air duct machine 10 reach the lower ground quickly, the rotating shaft 132 can be rotated to an appropriate angle so that the opening on the air outlet side of the air guide mechanism 100 is facing the surface as much as possible, so that the airflow compressed by the contracted opening on the air outlet side can flow quickly to the ground.

[0061] For another example, the user can also control the rotating shaft 132 to close the air guide mechanism 100. At this time, the first air guide plate 110 of the air guide mechanism 100 closes the air outlet 131, and the airflow inside the duct machine 10 will no longer flow into the working environment of the duct machine 10.

[0062] For example, Figure 7 As shown, in some cases, when the user needs a variety of different air supply solutions, two or more rotating shafts 132 can be rotated asynchronously, so that the interval openings limited by the first arc portion 113 and the second arc portion 123 on the air outlet side of different air guide mechanisms 100 are oriented in different directions, and the airflow inside the duct machine 10 that is deflected by the air guide mechanism 100 is blown in different directions. In actual use, different air supply solutions required by users can be met.

[0063] In some embodiments, two long openings are provided along the height direction on the air duct machine housing 200 to accommodate two air guide mechanisms 100. When in use, the two air guide mechanisms 100 can be rotated synchronously as needed. The airflow inside the air duct machine 10 flows into the external environment through the deflection of the two air guide mechanisms 100 and blows to the place where the airflow needs to be delivered. In addition, the two air guide mechanisms 100 can also be directed at different angles as needed to meet different air guide requirements.

[0064] The two air guide mechanisms 100 shown in the figure are only an example. Those skilled in the art may, according to the actual situation of the air outlet 131 and the needs of actual use, set two or more air guide mechanisms 100 in the height direction of the air outlet 131 to meet the different requirements of users for air supply, or may determine different air guide schemes according to the actual situation of the air outlet 131 and the specific number of air guide mechanisms 100.

[0065] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
