[0053] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0054] The air duct assembly according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The air duct assembly can be used in the air conditioner 100, and the air conditioner 100 can be a mobile air conditioner.

[0055] Referring to Figure 4 and Figure 5 , the air duct assembly according to the first aspect embodiment of the present invention includes: a housing, a fan assembly, and an air guiding member 6a. An accommodating cavity 21a and a rectifying cavity 11a that communicate with each other are defined in the housing. An air duct inlet 113 that communicates with the accommodating cavity 21a is formed on the housing, and a slit-shaped air outlet 111 is formed on the wall of the rectifying cavity 11a at the end far from the accommodating cavity 21a.

[0056] The fan assembly includes a wind wheel 211 and a motor 212 for driving the wind wheel 211 to rotate. The wind wheel 211 is arranged in the accommodation cavity 21a, and the accommodation cavity 21a and the rectification cavity 11a are arranged in the axial direction of the wind wheel 211.

[0057] When the air duct assembly is working, the motor 212 drives the wind wheel 211 to rotate. The air flow enters the shell from the air duct inlet 113, flows through the accommodation cavity 21a and the rectification cavity 11a in sequence, and is discharged from the air outlet 111 to the room. When the air duct assembly is used in the air conditioner 100, the indoor environmental temperature can be improved. During the process of the air flow flowing through the rectification cavity 11a, the air flow can be rectified to make the air flow more orderly. After being rectified by the rectification cavity 11a, the air flow is discharged from the slit-shaped air outlet 111 to the room. When the power and rotation speed of the wind wheel 211 are the same, the air supply distance can be increased, so that the air supply is farther, and a better refrigeration / heating effect can be achieved, and the energy consumption and noise are both lower.

[0058] Among them, the air outlet 111 can blow air directly forward, or can blow air forward and obliquely upward.

[0059] Optionally, the air outlet 111 can extend linearly or curvilinearly. For example, the air outlet 111 can be strip-shaped, arc-shaped or annular (such as circular, elliptical annular, polygonal annular, etc.).

[0060] According to Q (air volume)=S (air outlet area)·V (air speed), under the same air volume, the smaller the air outlet area, the greater the air outlet speed. Therefore, under the same air volume, the air can be sent farther, achieving a better refrigeration / heating effect. At the same time, according to Bernoulli's equation, for an incompressible fluid, there is: ρgh + 0.5ρv 2 +p = C, that is: gravitational potential energy + kinetic energy + pressure potential energy = constant. For a gas, the gravitational potential energy can be ignored. Therefore, the greater the kinetic energy, the smaller the pressure. Therefore, for a high-speed jet, a significant low pressure will be formed in the jet area, and this low pressure will form an adsorption and traction effect on the surrounding air, thereby increasing the total air flow rate, and further achieving the effect of long-distance air supply.

[0061] Optionally, the wind wheel 211 can be a centrifugal wind wheel, thereby further increasing the air supply distance. When the wind wheel 211 is a centrifugal wind wheel, the air outlet 111 can discharge air along the axial direction of the wind wheel 211. Specifically, the external air flow enters the housing, is pressurized by the wind wheel 211 and then radially thrown out from the wind wheel 211. The thrown high-pressure air flow is then redirected through the accommodation cavity 21a and the rectification cavity 11a and ejected from the air outlet 111. During the process of the air flow flowing from the accommodation cavity 21a to the rectification cavity 11a, the air flow changes from the radial direction of the wind wheel 211 to be generally along the axial direction of the wind wheel 211. The axial direction of the wind wheel 211 can extend in the front-rear direction. At this time, forward air supply can be achieved. Through the rectification effect of the rectification cavity 11a, the redirected air flow can be made more orderly and the air flow loss can be reduced.

[0062] Optionally, when the wind wheel 211 is a centrifugal wind wheel, at least a part of the rectification cavity 11a adjacent to the accommodation cavity 21a can be annular and extend around the central axis of the wind wheel 211. Thereby, after the air flow pressurized by the wind wheel 211 is radially thrown out from the wind wheel 211 and redirected, the air flow in each part in the circumferential direction of the wind wheel 211 can directly flow into the rectification cavity 11a, reducing the flow loss.

[0063] Optionally, the air duct inlet 113 and the air outlet 111 are arranged on both axial sides of the wind wheel 211. An air inlet opposite to and communicating with the air duct inlet 113 is formed on the housing of the air conditioner. Thereby, the air inlet and the air outlet 111 are located on both axial sides of the wind wheel 211, such that during the process of the air flow flowing through the internal space of the air conditioner 100, the air flow can generally flow along the axial direction of the wind wheel 211, making the air flow path simple and reducing the air flow path, reducing the air flow loss, further enabling the air flow to be blown farther, and reducing the mutual interference and influence of the air flow between the air inlet 112 and the air outlet 111.

[0064] Wherein, the air guiding member 6a is movably arranged on the housing. By the movement of the air guiding member 6a, the air guiding member 6a can have an air guiding state and a non-air guiding state. For example, the air guiding member 6a is rotatably or movably arranged on the housing, and the air guiding member 6a can realize the switching between the air guiding state and the non-air guiding state by rotation or movement. The air guiding member 6a includes an air guiding portion 61a. When the air guiding member 6a is in the air guiding state, the air guiding portion 61a is located downstream of the air outlet 111 and is arranged opposite to the air outlet 111. The air flow flowing out from the air outlet 111 can adjust and change the air flow direction of the air outlet 111 through the guiding action of the air guiding portion 61a of the air guiding member 6a, thereby adjusting the air outlet direction of the air outlet 111 and meeting more usage requirements of users.

[0065] When the air guide member 6a is in the non-air guiding state at the air guide member 6a, the air guide member 6a moves to make the air guiding portion 61a of the air guide member 6a away from the air outlet 111. The air guide member 6a is not disposed opposite to the air outlet 111, and the air guide member 6a does not play a role in guiding the air outlet 111, that is, it does not play a role in guiding the air flow. The air discharged from the air outlet 111 is discharged in the normal air outlet direction. When the air guide member 6a is in the air guiding state, the air guide member 6a moves to make the air guiding portion 61a of the air guide member 6a adjacent to the air outlet 111, so as to play a role in guiding the air flow of the air outlet 111, adjust the air outlet direction of the air outlet 111, and make the final air outlet direction of the air outlet 111 different from the normal air outlet direction of the air outlet 111.

[0066] Optionally, when the air guide member 6a is in the air guiding state, a part of the air outlet 111 may correspond to the air guiding portion 61a. For example, the extension length of the air guiding portion 61a may be less than the extension length of the air outlet 111. At this time, for the part of the air outlet 111 corresponding to the air guiding portion 61a, the air flow changes the air outlet direction under the guiding action of the air guiding portion 61a, and the part of the air outlet 111 not corresponding to the air guiding portion 61a is discharged in the normal air outlet direction. Thus, the air outlet direction of the air outlet 111 can be diversified at the same time, and the air outlet range can be expanded.

[0067] Optionally, when the air guide member 6a is in the air guiding state, the entire air outlet 111 may also correspond to the air guiding portion 61a. For example, the extension length of the air guiding portion 61a is not less than the extension length of the air outlet 111. The air flow of the entire air outlet 111 changes direction under the guiding action of the air guiding portion 61a, so that the entire air outlet 111 discharges air toward a set direction.

[0068] According to the air duct assembly of the embodiment of the present invention, by setting the air outlet 111 in a slit shape, the air flow is ejected through the air outlet 111, can be blown to a farther place, has a better refrigeration / heating effect, and has lower energy consumption and noise; at the same time, by providing the movable air guide member 6a, the air guide member 6a has an air guiding state and a non-air guiding state through the movement of the air guide member 6a, so that the air outlet direction of the air outlet 111 can be adjusted.

[0069] According to some embodiments of the present invention, refer to Figure 15 and Figure 18, the rectifying cavity 11a includes a first side wall 111b and a second side wall 112b extending along the length direction of the air outlet 111. The first side wall 111b and the second side wall 112b are opposite and spaced apart. An air outlet 111 is defined between the free ends of the first side wall 111b and the second side wall 112b. The distance W between the first side wall 111b and the second side wall 112b at the air outlet 111 is not greater than 0.05D, where D is the diameter of the impeller 211. Thus, it can be ensured that the air outlet of the air outlet 111 has a relatively large air outlet speed, so that it can be ensured that the air conditioner 100 can send air to a relatively far place.

[0070] According to some embodiments of the present invention, the length range of the air outlet 111 is 0.5D - 8D, where D is the diameter of the impeller 211. For example, when the air outlet 111 is annular, the length of the air outlet 111 is the circumference of the air outlet 111; when the air outlet 111 is strip-shaped, the length of the air outlet 111 is the extension length of the air outlet 111. Thus, while ensuring that the air outlet 111 has a relatively large air outlet speed, the air outlet area can be ensured, so that the air conditioner 100 can have a relatively large air outlet range, thereby further improving the cooling / heating performance of the air conditioner 100.

[0071] According to some embodiments of the present invention, referring to Figure 16 , in the axial direction of the impeller 211, the distance between the trailing edge of the blade of the impeller 211 and the air outlet 111 is d, and the value range of d is 0.1D - 1.5D, where D is the diameter of the impeller 211. Thus, after the air flow passes through the impeller 211 and before flowing out of the air outlet 111, the air flow has sufficient flow distance to adjust the flow direction of the air flow and make the air flow more orderly, reducing the flow loss. And while the air flow becomes more orderly in the rectifying cavity 11a, the flow path of the air flow in the rectifying cavity 11a can be made shorter, resulting in smaller flow resistance and flow loss.

[0072] According to some embodiments of the present invention, referring to Figure 3 and Figure 7, the housing includes a connected first housing 1a and a second housing 2a. The first housing 1a includes a first rectifying housing 111c, a second rectifying housing 112c, and a baffle 113c. The first rectifying housing 111c and the second rectifying housing 112c can be cylindrical or conical, and the baffle 113c can be substantially perpendicular to the rotation axis of the wind wheel 211. The first rectifying housing 111c is disposed around the outer periphery of the baffle 113c and the first rectifying housing 111c is connected to the baffle 113c. The baffle 113c is located at one end of the first rectifying housing 111c adjacent to the second housing 2a. The second rectifying housing 112c is disposed around the outer periphery of the first rectifying housing 111c. A support member is provided between the second rectifying housing 112c and the first rectifying housing 111c to space the second rectifying housing 112c and the first rectifying housing 111c apart, and both ends of the support member are respectively connected to the second rectifying housing 112c and the first rectifying housing 111c. The first rectifying housing 111c, the second rectifying housing 112c, and the baffle 113c jointly define a rectifying cavity 11a. The second housing 2a is cylindrical and defines a receiving cavity 21a. The second housing 2a can be cylindrical, and the second rectifying housing 112c is connected to the second housing 2a. After the air flow flows into the receiving cavity 21a and is pressurized by the wind wheel 211, the air flow can be radially ejected from the wind wheel 211. At the same time, the baffle 113c can prevent the air flow from diverging axially when flowing through the wind wheel 211, facilitate the formation of the rectifying cavity 11a and the receiving cavity 21a, and make the structure of the housing simple.

[0073] Wherein, the above-mentioned first side wall 111b can be a part of the first rectifying housing 111c, and the second side wall 112b can be a part of the second rectifying housing 112c (refer to Figures 1 - 8 ); the above-mentioned first side wall 111b and the second side wall 112b can both be parts of the second rectifying housing 112c.

[0074] Optionally, refer to Figure 15 and Figure 18 , the side of the rectifying cavity 11a facing the receiving cavity 21a is open to communicate with the receiving cavity 21a. The air flow flows out radially through the wind wheel 211 after flowing through the wind wheel 211. During the process of the air flow flowing from the receiving cavity 21a into the rectifying cavity 11a, the flow direction of the air flow changes from the radial direction of the wind wheel 211 to substantially along the axial direction of the wind wheel 211. After the air flow flows through the rectifying cavity 11a, it is blown out through the air outlet 111. Thus, the air inlet 112 of the rectifying cavity 11a has a larger space and area, and the air flow can directly flow into the rectifying cavity 11a through the receiving cavity 21a after flowing through the wind wheel 211, reducing the air flow loss.

[0075] According to some embodiments of the present invention, refer to Figure 4 , Figure 5 and Figure 13, in the flowing direction of the air flow, the flow area of the rectifying cavity 11a gradually decreases. Thus, during the process of the air flow passing through the rectifying cavity 11a for rectification, in the flowing direction of the air flow, the flow velocity of the air flow can be gradually increased, so that the air flow flows out of the air outlet 111 at a relatively high speed, thereby making the air supply distance of the air conditioner 100 farther.

[0076] According to some embodiments of the present invention, referring to Figure 11 and Figure 17 , at least one set of guide vane groups is provided in the rectifying cavity 11a. For example, one set of guide vane groups can be provided, or multiple sets of guide vane groups can be provided. Each set of guide vane groups includes a plurality of guide vanes 13a. The plurality of guide vanes 13a in each set are arranged at intervals along the circumferential direction of the rectifying cavity 11a. Each guide vane 13a can be connected to the inner wall of the rectifying cavity 11a to fix the guide vane 13a in the rectifying cavity 11a. When there are multiple sets of guide vane groups, the multiple sets of guide vanes 13a are arranged at intervals along the flowing direction of the air flow. Thus, through the provided guide vanes 13a, during the process of the air flow passing through the rectifying cavity 11a, the guide vanes 13a can further rectify the air flow, making the air flow more orderly and reducing air flow loss. The number of sets of guide vane groups 13a can be set according to the size of the rectifying cavity 11a and the distance that the air flow passes through the rectifying cavity 11a. While the guide vane groups 13a have a good rectifying effect on the air flow, the guide vanes 13a also have a relatively small resistance to the air flow, achieving a better comprehensive effect.

[0077] Wherein, when the housing includes the above-mentioned connected first housing 1a and second housing 2a, and the first housing 1a includes the above-mentioned first rectifying shell 111c, second rectifying shell 112c and baffle 113c, for the above-mentioned guide vanes 13a arranged in the rectifying cavity 11a, both ends of the guide vanes 13a are respectively connected to the second rectifying shell 112c and the first rectifying shell 111c. At this time, the guide vanes 13a can be used as the above-mentioned supporting members. Thus, the guide vanes 13a can not only play a rectifying role, but also realize the function of separating the second rectifying shell 112c and the first rectifying shell 111c.

[0078] It should be noted that the "plurality" mentioned in the present invention refers to two or more.

[0079] According to some embodiments of the present invention, referring to Figure 11 and Figure 13, the housing includes a first housing 1a and a second housing 2a that are detachably connected. A rectifying chamber 11a is defined within the first housing 1a, and a receiving chamber 21a is defined within the second housing 2a. Thus, by defining the rectifying chamber 11a and the receiving chamber 21a through two detachable parts respectively, it facilitates the maintenance, replacement, etc. of internal components of the air conditioner 100 such as the impeller 211 and the motor 212. And according to the air outlet requirements, the second housing 2a of the same specification can be matched with the first housing 1a having different rectifying chambers 11a or air outlets 111. Thus, it is possible to produce air conditioners 100 with different air outlet effects while only changing the structure of the first housing 1a and keeping other structures of the air conditioner 100 unchanged, reducing the types of materials and saving production costs.

[0080] Optionally, the first housing 1a and the second housing 2a can be detachably connected through a snap structure; alternatively, the first housing 1a and the second housing 2a can also be detachably connected through a fastener such as a screw; or, the first housing 1a and the second housing 2a are detachably connected through a snap structure and a fastener.

[0081] It should be noted that the directions of "front", "rear", "left", and "right" described in this application are all relative to the direction of the air conditioner 100 during use, where the direction facing the user of the air conditioner 100 is the front.

[0082] According to some embodiments of the present invention, referring to Figure 5 and Figure 13 , when the air guiding member 6a is in the air guiding state, the air guiding portion 61a extends along the length direction of the air outlet 111, the width range of the air guiding portion 61a is 3W - 10W, the rectifying chamber 11a includes a first side wall 111b and a second side wall 112b that extend along the length direction of the air outlet 111. The first side wall 111b and the second side wall 112b are opposite and spaced apart. An air outlet 111 is defined between the free ends of the first side wall 111b and the second side wall 112b, and the distance between the first side wall 111b and the second side wall 112b at the air outlet 111 is the W. Thus, while ensuring that the air guiding portion 61a plays a role in guiding the air, the air resistance can be made lower and the wind speed loss can be made smaller.

[0083] It should be noted that when the air outlet 111 is annular, the length direction of the air outlet 111 is the circumferential direction of the air outlet 111; when the air outlet 111 is elongated, the length direction of the air outlet 111 is the length direction of the air outlet 111.

[0084] According to some embodiments of the present invention, referring to Figure 5 and Figure 13, when in the air guiding state at the air guiding member 6a, the distance between the air outlet 111 and the air guiding portion 61a is L, and the value range of L is 2 - 15 mm. When the distance between the air outlet 111 and the air guiding portion 61a is less than 2 mm, the air resistance is large and obvious noise is generated; when the distance between the air outlet 111 and the air guiding portion 61a is greater than 15 mm, the air flow has diverged and the air guiding portion 61a cannot achieve the air guiding effect. Thus, by setting the distance L between the air outlet 111 and the air guiding portion 61a between 2 - 15 mm, the air guiding function can be achieved, and at the same time, the air resistance can be made smaller and the noise can be made lower.

[0085] According to some embodiments of the present invention, referring to Figure 5 , Figure 10 and Figure 19 , the rectifying cavity 11a includes an air outlet passage 111a, and an air outlet 111 is formed at the free end of the air outlet passage 111a. There is an included angle between the center line of the air outlet passage 111a and the horizontal direction. For example, the included angle γ between the center line of the air outlet passage 111a and the horizontal direction may not be greater than 45°. Thus, the air outlet 111 can be made to blow air obliquely upward or obliquely downward. For example, when the air duct assembly is used for a mobile air conditioner, in the direction from the accommodating cavity 21a to the rectifying cavity 11a, the air outlet passage 111a extends obliquely upward, so that the normal air outlet of the air outlet 111 is obliquely upward. And, through the arranged air guiding member 6a, when the air guiding member 6a is in the air guiding state, the air outlet direction of the air outlet 111 can be changed. For example, the air outlet 111 can be made to blow air forward.

[0086] According to some embodiments of the present invention, referring to Figure 5 and Figure 13 , the rectifying cavity 11a includes an air outlet passage 111a, and an air outlet 111 is formed at the free end of the air outlet passage 111a. When the air guiding member 6a is in the air guiding state, the included angle between the center line of the air outlet passage 111a and the air guiding portion 61a is α, and the value range of α is 15 - 60°. If the above α angle is too small, the air guiding portion 61a cannot achieve the air guiding effect; if the above α angle is too large, the air flow loss is too large and the wind speed decays quickly, affecting the air supply distance. Thus, by setting the included angle α between the center line of the air outlet passage 111a and the air guiding portion 61a between 15 - 60°, while ensuring that the air guiding portion 61a has a good air guiding effect, the air flow loss is reduced, and the air outlet speed is ensured to be relatively large, so as to ensure a relatively large air supply distance.

[0087] According to some embodiments of the present invention, referring to Figures 1 - 16, the air guiding member 6a is movably provided on the housing. Thus, by moving the air guiding member 6a, it is convenient to switch between the air guiding state and the non-air guiding state of the air guiding member 6a. For example, a guide rail for guiding the movement of the air guiding member 6a can be formed on the housing, and the air guiding member 6a is slidably provided on the guide rail along the extending direction of the guide rail. By sliding the air guiding member 6a along the guide rail, the air guiding member 6a can be made to be adjacent to or away from the air outlet 111, so that the air guiding portion 61a is adjacent to or away from the air outlet 111. The air guiding member 6a can be driven to move by a driving mechanism, and the movement of the air guiding member 6a can also be manually moved. When the air guiding member 6a moves to the air guiding state or the non-air guiding state, the air guiding member 6a can be positioned by the frictional force between the air guiding member 6a and the housing or a positioning member.

[0088] Optionally, the movement trajectory of the air guiding member 6a can be a straight line, thus making the movement trajectory of the air guiding member 6a simple and easy to operate. The included angle range between the movement trajectory of the air guiding member 6a and the horizontal direction is 0 - 90°, thus making the design of the movement trajectory of the air guiding member 6a more flexible to adapt to different specifications of the air duct assembly or the air conditioner 100.

[0089] For example, in Figures 11 - 16 example, the air outlet 111 is formed as a long strip, which can make the structure of the air outlet 111 simple and the air outlet more concentrated. There is one air outlet 111 and it extends in the left - right direction. The rectifying cavity 11a includes an air outlet passage 111a, and the free end of the air outlet passage 111a forms the air outlet 111. In the direction from the accommodating cavity 21a to the rectifying cavity 11a, the air outlet passage 111a extends obliquely upward. Thus, the air flow exits through the obliquely extending air outlet passage 111a, which can make the air outlet of the air outlet 111 face forward and obliquely upward. When the air conditioner 100 is cooling, the temperature uniformity can be improved. For example, when the air conditioner 100 is a mobile air conditioner, the height of the air outlet 111 is relatively lower than that of other types of air conditioners 100. By making the air outlet of the air outlet 111 face forward and obliquely upward, the temperature non - uniformity caused by the relatively low air outlet position can be improved.

[0090] The housing is provided with a movable air guiding member 6a. The air guiding member 6a is in a flat plate shape and can be substantially parallel to the horizontal direction (when the air guiding member 6a is in the air guiding state and the non - air guiding state, the air guiding member 6a can be substantially parallel to the horizontal direction). When the air guiding member 6a is in the non - air guiding state, the air outlet 111 blows air obliquely upward; when the air guiding member 6a is in the air guiding state, the air guiding member 6a is located above the air outlet 111, and the air outlet 111 blows air straight forward. The air guiding member 6a can move in the up - down direction (refer to Figure 13 and Figure 15 ), when the air guiding member 6a switches to the air guiding state (refer to Figure 13), the air guiding member 6a can move downward to a position adjacent to the air outlet 111; when the air guiding member 6a switches to the non-air guiding state (refer to Figure 15 ), the air guiding member 6a can move upward to a position away from the air outlet 111. The air guiding member 6a can move in the front-rear direction (refer to Figure 13 and Figure 16 ). When the air guiding member 6a switches to the air guiding state (refer to Figure 13 ), the air guiding member 6a can move forward to a position adjacent to the air outlet 111; when the air guiding member 6a switches to the non-air guiding state (refer to Figure 16 ), the air guiding member 6a can move backward to a position away from the air outlet 111.

[0091] Optionally, the movement trajectory of the air guiding member 6a can also be a broken line, a curve or other types of paths.

[0092] In some specific embodiments of the present invention, refer to Figures 1 - 10 , a storage cavity 16a for storing the air guiding member 6a is formed on the housing. The air guiding member 6a is movably disposed in the storage cavity 16a. When the air guiding member 6a is in the air guiding state, at least a part of the air guiding member 6a extends out of the storage cavity 16a; when the air guiding member 6a is in the non-air guiding state, the air guiding member 6a is completely stored in the storage cavity 16a. Thus, by providing the storage cavity 16a on the housing, it is convenient to store the air guiding member 6a in the non-air guiding state, making the overall structure of the machine compact and beautiful. When the air guiding member 6a is in the non-air guiding state, it can prevent dust from accumulating on the air guiding member 6a.

[0093] For example, in the example of Figures 1 - 10 , the air outlet 111 is formed as a curved arc facing downward. There is one air outlet 111 and it generally extends in the left-right direction. The air guiding member 6a is integrally in the shape of an arc-shaped plate, and the air guiding portion 61a is also formed as an arc. The rectifying cavity 11a includes an air outlet passage 111a. The free end of the air outlet passage 111a forms the air outlet 111. In the direction from the accommodating cavity 21a to the rectifying cavity 11a, the air outlet passage 111a extends obliquely upward. The above-mentioned storage cavity 16a is formed in the upper part of the housing. The air guiding member 6a is movably disposed in the storage cavity 16a in the front-rear direction. When the air guiding member 6a switches to the air guiding state (refer to Figure 5 ), the air guiding member 6a can move forward to extend out of the storage cavity 16a, so that the air guiding portion 61a of the air guiding member 6a moves to a position adjacent to the air outlet 111; when the air guiding member 6a switches to the non-air guiding state (refer to Figure 10 ), the air guiding member 6a moves backward to be completely stored in the storage cavity 16a, and the air guiding member 6a does not play an air guiding role.

[0094] According to some embodiments of the present invention, refer to Figures 17 - 19, the air guiding member 6a is rotatably provided on the housing. Thus, by rotating the air guiding member 6a, it is convenient to switch between the air guiding state and the non-air guiding state of the air guiding member 6a. For example, one of a rotation hole and a rotation shaft 1b may be formed on the housing, and the air guiding member 6a has the other of the rotation shaft 1b and the rotation hole. By rotating the air guiding member 6a, the air guiding member 6a can be made to be adjacent to or away from the air outlet 111, so that the air guiding portion 61a faces the air outlet 111 or is away from the air outlet 111. The air guiding member 6a can be driven to rotate by a driving mechanism, and the rotation of the air guiding member 6a can also be achieved manually. When the air guiding member 6a rotates to the air guiding state or the non-air guiding state, the positioning of the air guiding member 6a can be achieved by the frictional force between the air guiding member 6a and the housing or a positioning member.

[0095] Optionally, the rotation axis of the air guiding member 6a is parallel to the connection line of the two ends in the length direction of the air outlet 111. Thus, the rotation of the air guiding member 6a can be controlled better and more conveniently.

[0096] Optionally, referring to Figure 19 , the rotation angle β of the air guiding member 6a ranges from 30° to 135°. The rotation angle of the air guiding member 6a refers to the angle through which the air guiding member 6a rotates from the air guiding state to the non-air guiding state or the angle through which the air guiding member 6a rotates from the non-air guiding state to the air guiding state. Thus, the air guiding member 6a has a relatively large rotation range. When the air guiding member 6a has different rotation ranges, the air guiding member 6a can have different air guiding states to meet the user's usage requirements.

[0097] For example, in Figures 17 - 19 's example, the air outlet 111 is formed in a long strip shape, which can make the structure of the air outlet 111 simple and the air outlet more concentrated. There is one air outlet 111 and it extends in the left-right direction. The rectifying cavity 11a includes an air outlet channel 111a, and the free end of the air outlet channel 111a forms the air outlet 111. In the direction from the accommodation cavity 21a to the rectifying cavity 11a, the air outlet channel 111a extends obliquely upward. Thus, the air flow exits through the obliquely extending air outlet channel 111a, which can make the air outlet of the air outlet 111 face forward and obliquely upward. When the air conditioner 100 is cooling, the temperature uniformity can be improved. For example, when the air conditioner 100 is a mobile air conditioner, the height of the air outlet 111 is relatively low compared to other types of air conditioners 100. By making the air outlet of the air outlet 111 face forward and obliquely upward, the temperature non-uniformity caused by the relatively low air outlet position can be improved.

[0098] A rotatable air guiding member 6a is provided on the housing. The air guiding member 6a is in a flat plate shape, and the rotation angle of the air guiding member 6a is 90°. When the air guiding member 6a is in the air guiding state (refer to Figure 19), the air guide member 6a is located above the air outlet 111, the air guide member 6a can be substantially parallel to the horizontal direction, and the air outlet 111 blows air forward. When the air guide member 6a is in the non-air guiding state (refer to Figure 18 ), the included angle between the air guide member 6a and the horizontal direction can be 90°, and the air outlet 111 blows air obliquely upward.

[0099] The air conditioner 100 according to the second aspect embodiment of the present invention includes: the air duct assembly according to the first aspect embodiment of the present invention above. An air inlet 112 is formed on the housing 1 of the air conditioner 100, and the air duct assembly can be disposed inside the housing 1. Among them, most of the housing can be located inside the housing 1, and the part of the housing adjacent to the air outlet 111 can be located outside the housing 1. Optionally, the air conditioner 100 can be a mobile air conditioner.

[0100] When the air conditioner 100 is working, the motor 212 drives the air wheel 211 to rotate. The air flow enters the housing 1 from the air inlet 112, enters the housing through the air duct inlet 113, exchanges heat with the heat exchanger 4a, then flows through the accommodation cavity 21a and the rectification cavity 11a in sequence, and is discharged from the air outlet 111 to the room, thereby improving the indoor environmental temperature. During the process of the air flow flowing through the rectification cavity 11a, the air flow can be rectified to make the air flow more orderly. The air flow is discharged from the slit-shaped air outlet 111 to the room after being rectified by the rectification cavity 11a. When the power and speed of the air wheel 211 are the same, the air supply distance can be increased, so that the air supply is farther, achieving a better cooling / heating effect, and the energy consumption and noise are both lower. At the same time, by the movement of the air guide member 6a, the air outlet direction of the air outlet 111 can be adjusted to meet more air outlet requirements of users.

[0101] The air conditioner 100 according to the embodiment of the present invention can make the air supply distance of the air conditioner 100 farther, achieve a better cooling / heating effect, and the energy consumption and noise are both lower by setting the above air duct assembly; at the same time, by the movement of the air guide member 6a, the air outlet direction of the air outlet 111 can be adjusted to meet more air outlet requirements of users.

[0102] Optionally, refer to Figure 3 、 Figure 8 、 Figure 12, the heat exchanger 4a of the air conditioner 100 can be in a flat plate shape. Thus, the structure of the heat exchanger 4a is simple and easy to manufacture, and it can ensure that the heat exchanger 4a has a large heat exchange area, guaranteeing the heat exchange quantity and heat exchange effect, and making the overall structure of the air conditioner 100 simple and compact. For example, the heat exchanger 4a can be arranged substantially perpendicular to the central axis of the wind wheel 211. When the air conditioner 100 operates, the air flow enters the housing 1 from the air inlet 112 and then exchanges heat with the flat plate-shaped heat exchanger 4a. The air flow passes through the heat exchanger 4a and exchanges heat with the heat exchanger 4a sufficiently, so that there is a large heat exchange area between the air flow and the heat exchanger 4a, ensuring the heat exchange effect.

[0103] For example, in Figure 11 and Figure 19 example (and in combination with Figures 1 - 10 ), the air conditioner 100 is a mobile air conditioner. The air conditioner 100 includes an upper air duct system 20 and a lower air duct system 30 arranged at an upper and lower interval. The upper air duct system 20 includes the above-mentioned air duct assembly and the heat exchanger 4a. The upper air duct system 20 and the lower air duct system 30 are separated by a partition plate 5a. The housing 1 includes a first housing 1a, a second housing 2a, and a third housing 3c. The first housing 1a, the second housing 2a, and the third housing 3c are arranged in sequence along the axial direction of the wind wheel 211. The first housing 1a, the second housing 2a, and the third housing 3c are all arranged on the partition plate 5a. The first housing 1a and the second housing 2a are detachably connected, and the second housing 2a and the third housing 3c are connected. For example, the second housing 2a and the third housing 3c can be detachably connected, or the second housing 2a and the third housing 3c can be integrally formed. A rectifying cavity 11a is defined in the first housing 1a, and an air outlet 111 is formed on the front side wall of the first housing 1a. A receiving cavity 21a is defined in the second housing 2a, and the wind wheel 211 is received in the receiving cavity 21a. The wind wheel 211 is a centrifugal wind wheel, and the rotation axis 1b of the wind wheel 211 extends in the front-rear direction. A heat exchange cavity 31c is defined in the third housing 3c, and the heat exchanger 4a is received in the heat exchange cavity 31c. The heat exchange cavity 31c is communicated with the receiving cavity 21a. An air duct inlet 113 is formed on the rear wall of the third housing 3c. An air inlet 112 is formed at a position of the housing 1 of the air conditioner 100 opposite to the air duct inlet 113 in the axial direction. The heat exchanger 4a is in a flat plate shape and is arranged opposite to the air inlet 112.

[0104] The motor 212 can be disposed on the side of the wind wheel 211 away from the air duct inlet 113. For example, a part of the wall of the rectifying cavity 11a protrudes in a direction away from the wind wheel 211 to form a motor cavity, and the motor 212 is disposed in the motor cavity. The motor 212 can also be disposed on the side of the wind wheel 211 adjacent to the air duct inlet 113. At this time, the motor 212 is located between the heat exchanger 4a and the wind wheel 211. The motor 212 can be disposed in the accommodation cavity 21a, or the motor 212 can be disposed in the heat exchange cavity 31c, or a part of the motor 212 is accommodated in the accommodation cavity 21a and another part is accommodated in the heat exchange cavity 31c.

[0105] When the air conditioner 100 is operating, air flows into the heat exchange cavity 31c from the air duct inlet 113 and exchanges heat with the heat exchanger 4a. The heated air then flows into the accommodation cavity 21a, is accelerated by the wind wheel 211, and then flows into the rectifying cavity 11a for rectification. Finally, the air is blown out from the air outlet 111 into the room. During the process of the air flowing through the interior of the air conditioner 100, the general flow direction of the air is from the rear to the front, making the air flow path simple and short. At the same time, since the air outlet 111 is in a slit shape, the air outlet speed of the air outlet 111 can be relatively high, enabling the air conditioner 100 to have a longer air supply distance and improving the cooling / heating performance of the air conditioner 100.

[0106] Moreover, the air guiding state and non-air guiding state of the air guiding member 6a can be switched by means of movement or rotation, etc., and the air outlet direction of the air outlet 111 can be adjusted.
