Description

Technical Field

[0001] The present invention relates to the technical field of air treatment, and in particular to an air supply device and an air treatment unit. Background Art

[0002] In the related art, the air outlet range of the air supply device is relatively small, and the air outlet angle is controlled only by the up and down rotation of the air guide plate. Therefore, the air outlet can often only cover an area in front of the air outlet. Taking a ceiling-mounted air conditioner as an example, in order to meet the needs, the air outlet angle needs to cover as wide an area as possible. However, due to the size and internal structure layout of the ceiling-mounted air conditioner, it is difficult to make the left and right wind swing components large enough. Therefore, the wind blown to the left and right will quickly decay in speed, making it difficult to achieve long-distance air supply over a large range to the left and right, resulting in uneven temperature on both sides. In addition, the air guide plate at the air outlet of the ceiling-mounted air conditioner in the related art is often relatively simple, and can only achieve uniform upward or uniform downward blowing of the air outlet. It is difficult to adjust according to the actual scene, making it difficult to achieve separate control of multiple areas. Therefore, in order to achieve full coverage of the air outlet, customers are often required to install multiple air supply devices, resulting in increased purchase and use costs.

[0062] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0065] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0066] In the related art, the air outlet range of the air supply device is relatively small, and the air outlet angle is controlled only by the up and down rotation of the air guide plate. Therefore, the air outlet can often only cover an area in front of the air outlet. Taking a ceiling-mounted air conditioner as an example, in order to meet the needs, the air outlet angle needs to cover as wide an area as possible. However, due to the size and internal structure layout of the ceiling-mounted air conditioner, it is difficult to make the left and right wind swing components large enough. Therefore, the wind blown to the left and right will quickly decay in speed, making it difficult to achieve long-distance air supply over a large range to the left and right, resulting in uneven temperature on both sides. In addition, the air guide plate at the air outlet of the ceiling-mounted air conditioner in the related art is often relatively simple, and can only achieve uniform upward or uniform downward blowing of the air outlet. It is difficult to adjust according to the actual scene, making it difficult to achieve separate control of multiple areas. Therefore, in order to achieve full coverage of the air outlet, customers are often required to install multiple air supply devices, resulting in increased purchase and use costs.

[0067] Specifically, in related technologies, air supply devices control the vertical air outlet angles through the forward and reverse rotation of a single air guide plate. This type of air outlet often results in the air outlet only covering an area directly in front of the air outlet. In addition, some air supply devices also have an internal air guide plate that can swing left and right as a wind swing component. However, due to the compact internal structure, the left and right wind swing components are located below the heat exchanger fins and above the water tray, and the space is relatively small. Therefore, the wind swing components are relatively small, and the air outlet coverage area is still small.

[0068] In view of this, see Figures 1-9 In an embodiment of the present invention, an air supply device 100 is provided. The air supply device 100 is used in an air handling unit. The air handling unit can be any type of device for directing airflow and controlling the airflow and temperature of the surrounding environment. For example, in some embodiments, the air handling unit can be any one of a wall-mounted air conditioner, a ceiling-mounted air conditioner, a ducted air conditioner, and a fan coil unit. For ease of description, the following embodiment uses a ceiling-mounted air conditioner as an example. Different embodiments can be combined with different technical solutions. Furthermore, the air supply device 100 includes a housing 110, an air supply assembly 120, and an air guide assembly 130.

[0069] For details, see Figure 1-Figure 2 The housing 110 has a first cavity 111 and an opening 112 communicating with the first cavity 111. The first cavity 111 can be represented as an inner cavity defined by the housing 110 itself, and the opening 112 can be an air inlet of the air supply device 100, or other openings 112 for communicating airflow.

[0070] See also Figure 1-Figure 2, the air supply component 120 and the air guide component 130 are both arranged in the first cavity 111. It should be noted that, in different embodiments, the air supply component 120 or the air guide component 130 can be located entirely within the first cavity 111, or partially within the first cavity 111. Among them, the air supply component 120 is used to generate an airflow to be exported out of the opening 112. It should be noted that, in some embodiments, the air supply component 120 can both generate airflow and export the airflow from the opening 112; in other embodiments, the air supply component 120 can only be used to receive the airflow and export the airflow from the opening 112, that is, it can only play the role of transmitting the airflow. From the above description, for example, in some embodiments, the air supply component 120 can be an air supply housing / duct (which can include an air inlet) for guiding air, or it can be a blower that can exhaust and supply air.

[0071] Also, see Figure 1-Figure 2 , the air guide assembly 130 includes an annular shell 131 in the shape of a ring. It should be noted that, in the present invention, the ring only refers to an annular structure without limiting its specific shape. Therefore, the ring can include any form of ring such as a circular ring, an elliptical ring, a rectangular ring, etc. The annular shell 131 can define a cavity for airflow. The annular shell 131 has a first port 13121 and a second port 13111 that are relatively arranged. Thus, the first port 13121 is used to obtain airflow, and the second port 13111 is used to export airflow. It can be understood that the airflow can be introduced into the annular shell 131 by the first port 13121, and can be exported by the second port 13111.

[0072] Furthermore, the annular shell 131 includes a first shell portion 1311 disposed around the second port 13111. It is understood that the first shell portion 1311 can define the second port 13111, and specifically can be a housing portion of the annular shell 131 extending around the axis of the second port 13111.

[0073] Specifically, the first shell portion 1311 is configured to rotate relative to the housing 110 about a first axis L1, with the first axis L1 intersecting the axis of the opening 112. It will be appreciated that this rotation can adjust the direction of airflow directed from the second port 13111. Furthermore, the intersection of the first axis L1 and the axis of the opening 112 means that, while airflow can be directed from the opening 112 to the first port 13121, the first shell portion 1311 can, through rotation about the first axis L1, change the direction of airflow directed from the first port 13121 to the second port 13111, thereby changing the outlet direction of air from the second port 13111. In some embodiments, the first shell portion 1311 can be used to represent the portion of the annular housing 131 that is capable of rotating relative to the housing 110 about the first axis L1. When the annular housing 131 is capable of rotating relative to the housing 110 about the first axis L1, the first shell portion 1311 can be the entire annular housing 131.

[0074] According to the combination of the above embodiments, it can be seen that the air supply device 100 of the present invention includes a housing 110, an air supply assembly 120, and an air guide assembly 130. Among them, the air supply assembly 120 can guide the airflow out of the opening 112, and the airflow can be guided to the first port 13121 of the air guide assembly 130 and guided out by the second port 13111, thereby forming the air supply process of the air supply device 100. In particular, the first shell portion 1311 is configured to be able to rotate around the first axis L1 relative to the housing 110, and the first axis L1 intersects with the axis of the opening 112. As a result, while the airflow flows within the first shell portion 1311, the air outlet direction can be changed by rotation. Compared to the related art, where the air outlet adjustment method is based on the swinging of the air guide plate 13114 set inside the air outlet cavity, the annular shell 131 of the present invention can not only adjust the air outlet direction, but also store and transport the airflow. As a result, the loss of air volume and air pressure is small during the adjustment of the air outlet direction, and the air outlet effect is better. From the perspective of layout, the number of air conditioners can be reduced, which can avoid excessive space occupation in the room and damage to the indoor scene layout. It can also reduce the difficulty of installing the duct and reduce damage to the ceiling and walls. Therefore, the air supply device 100 of the present invention can reduce the loss of air volume and air pressure while adjusting the air outlet direction.

[0075] As for the specific rotation form of the first shell 1311, the first shell 1311 can be set with different rotation angles and rotation limit positions according to needs. Specifically, the first shell 1311 can have a first limit position and a second limit position for rotating around the first axis L1. It can be understood that the first limit position and the second limit position correspond to two limit positions of circumferential rotation in opposite directions of the first shell 1311. For the sake of convenience, it is defined that when the first shell 1311 is in the first limit position, the axial direction of the second port 13111 is the first direction X, and when the first shell 1311 is in the second limit position, the axial direction of the second port 13111 is the second direction Y. It can be understood that the axial direction of the above-mentioned second port 13111 is expressed as the direction facing the second port 13111. Therefore, the first direction X and the second direction Y respectively correspond to the directions facing the second port 13111 when the first shell 1311 is rotated to the above-mentioned two limit positions, and correspond to the air outlet direction at this time. Therefore, see Figure 3-Figure 4 In some embodiments, the minimum angle φ between the first direction X and the second direction Y can satisfy the following: 0° ≤ φ ≤ 45°. The above angle setting indicates that the rotation angle range of the first shell portion 1311 around the first axis L1 is 0° to 45°. For example, in some embodiments, φ can be one of 0°, 10°, 20°, 30°, 40°, and 45°.

[0076] According to the requirements, the first shell 1311 can make the airflow cover different areas when rotating. Figure 5 , for the convenience of explanation, the direction along the axis perpendicular to the first axis L1 and the opening 112 is defined, and the first axis L1 has a first side S1 and a second side S2 relative to each other. Among them, for the convenience of description, the horizontal direction refers to the direction perpendicular to the first axis L1 and the axis of the opening 112 in the following text, and the horizontal direction may not be the horizontal direction, and the direction may change accordingly in different embodiments. It can be understood that the first side S1 and the second side S2 are two parts of the space along the horizontal direction of the first axis L1. Therefore, based on the definition of the first direction X and the second direction Y in the above embodiment. For the first shell portion 1311, see Figure 3-Figure 5 In the embodiment of the first rotation range, the first direction X is parallel to the first axis L1, and the second direction Y intersects the first axis L1. It can be understood that in this type of embodiment, the first direction X corresponds to the direction of the first axis L1 of the opening 112, and the second direction Y is offset from the first axis L1. In this way, the first shell 1311 can only discharge air in the direction parallel to the first axis L1 and on one side of the first axis L1 (the first side S1 or the second side S2). Figure 3 as well as Figure 6In the embodiment of the second rotation range, the second port 13111 can be suitable for exporting airflow toward the first side S1 along the first direction X, and the second port 13111 can be suitable for exporting airflow toward the second side S2 along the second direction Y. It can be understood that in this type of embodiment, when the first shell 1311 is rotated to the two extreme positions, it can discharge air to the two opposite sides of the first axis L1 (i.e., the first side S1 and the second side S2) respectively. Therefore, taking the first axis L1 parallel to the vertical direction as an example, the first shell 1311 at this time can discharge air to both sides in the horizontal direction by rotating to make the air outlet range larger. In the embodiment of the third rotation range, the second port 13111 can be suitable for exporting airflow toward the first side S1 along the first direction X or the second direction Y. It can be understood that in this type of embodiment, when the first shell 1311 is rotated to the two extreme positions, it can discharge air toward the first side S1 to adapt to the air outlet requirements of different angles on this side.

[0077] Furthermore, according to the requirements, the annular shell 131 can be configured so that only the first shell portion 1311 can rotate, or it can be configured so that the entire shell can rotate. Specifically, in some embodiments, the annular shell 131 can be configured so that it can rotate around the first axis L1 relative to the outer shell 110. It can be understood that the annular shell 131 as a whole (including the first shell portion 1311) can rotate together around the first axis L1 to meet the corresponding air supply requirements. The above-mentioned arrangement is conducive to reducing the complexity of the rotating structure and making the airflow between the first port 13121 and the second port 13111 more stable. Accordingly, see Figure 7In other embodiments, the annular shell 131 may further include a fixed portion 1312 connected to the first shell portion 1311. The fixed portion 1312 may have a first port 13121. In other words, the first port 13121 may be the opening 112 of the fixed portion 1312, and the fixed portion 1312 communicates with the first shell portion 1311 to facilitate airflow. Thus, when the first shell portion 1311 rotates relative to the housing 110 about the first axis L1, the fixed portion 1312 can be configured to remain fixed relative to the housing 110. It is understandable that while the first shell portion 1311 rotates relative to the outer shell 110, the fixed portion 1312 can be relatively stationary. This arrangement, on the one hand, can facilitate the connection of the annular shell 131 with other parts (the outer shell 110, the air supply assembly 120, etc.) because the fixed portion 1312 is relatively stationary. On the other hand, it can also save the internal layout space of the first cavity 111 by reducing the rotation of the annular shell 131 in the first cavity 111, that is, avoid the problem of a large rotation space occupied by the annular shell 131 as a whole. It should be noted that in some embodiments, in addition to the first shell portion 1311 and the fixed portion 1312, the annular shell 131 can also include other parts that can rotate relative to each other; in addition, according to needs, while the fixed portion 1312 is fixed relative to the outer shell 110, the fixed portion 1312 can be fixedly connected to the outer shell 110 or not connected to the outer shell 110.

[0078] In addition, it can be seen from the description of the above embodiments that the first shell 1311 can achieve multi-directional air outlet coverage of the annular shell 131 by rotating around the first axis L1. However, due to the size of the first shell 1311 and the requirements for air volume, a single air outlet often cannot meet user needs. Figures 1-6 In some embodiments, the annular shell 131 may further include a second shell portion 1313. The second shell portion 1313 may have a third port 13131. The second port 13111 and the third port 13131 may both be used to direct airflow. Similar to the configuration of the first shell portion 1311, the second shell portion 1313 may be configured to rotate relative to the housing 110 about the second axis L2, with the first axis L1 intersecting the second axis L2. To achieve a wider range of airflow, the first shell portion 1311 and the second shell portion 1313 may be arranged relative to each other in a direction perpendicular to the first axis L1 and the axis of the opening 112. It can be understood that the first shell 1311 and the second shell 1313 are a group of air outlet components arranged in parallel, and the two can be responsible for exporting airflow to different areas respectively. Due to similar functions, the structural forms of the first shell 1311 and the second shell 1313 (or the second port 13111 and the third port 13131) can be the same or similar; according to needs, the structural forms of the first shell 1311 and the second shell 1313 (or the second port 13111 and the third port 13131) can also be different.

[0079] In addition, in order to meet more diverse air supply needs, in some embodiments, in addition to the first shell 1311 and the second shell 1313, the air guide assembly 130 may also include other shell structures for air outlet, and the air outlet can cover a larger area. For the convenience of description, the following is an embodiment in which the air outlet structure of the air guide assembly 130 only includes the first shell 1311 and the second shell 1313 (that is, the air flow is only exported through the first shell 1311 or the second shell 1313). Different embodiments can be combined with each other between different technical solutions.

[0080] Regarding the airflow conduction form between the first shell 1311 and the second shell 1313, in some embodiments, the air supply component 120 can use one channel to simultaneously connect the first shell 1311 and the second shell 1313, so as to provide airflow to both at the same time, and enable the airflow to be simultaneously exported from the second port 13111 and the third port 13131. This setting makes the setting of the airflow channel simpler; in other embodiments, corresponding to the two shells, the air supply component 120 can also use two different channels to independently send the airflow to the first shell 1311 and the second shell 1313. This setting can more flexibly control the air volume exported from the second port 13111 and the third port 13131, and the airflows in the two shells are not easy to interfere with each other.

[0081] Based on the configuration of the above embodiments, the first shell 1311 and the second shell 1313 can be rotated to cover different areas according to the needs. Figure 5 , using the first side S1 and the second side S2 of the first axis L1 defined in the above embodiment, for the convenience of explanation, it is further defined that along the direction perpendicular to the first axis L1 and the axis of the opening 112, the side of the second shell portion 1313 close to the first shell portion 1311 is the third side S3, and the side of the second shell portion 1313 away from the first shell portion 1311 is the fourth side S4.

[0082] Based on this, for the case where both the first shell 1311 and the second shell 1313 rotate, see Figure 6In the embodiment of the first rotation range, the air guide assembly 130 can be configured to enable the second port 13111 to guide the airflow toward the first side S1, and enable the third port 13131 to guide the airflow toward the third side S3. It can be understood that in this type of embodiment, under the premise that the second port 13111 guides the air toward the first side S1, the third port 13131 can guide the air toward the side of the second axis L2 that is relatively close to the second port 13111, that is, at this time, the first port 13121 and the second port 13111 can both guide the air toward the same side. In this way, the two can play a common role in promoting the airflow, and make the air volume on that side larger and the air supply distance longer. See Figure 6 In the embodiment of the second rotation range, the air guide assembly 130 can be configured to enable the second port 13111 to guide the airflow toward the first side S1, and enable the third port 13131 to guide the airflow toward the fourth side S4. It can be understood that in this type of embodiment, under the premise that the second port 13111 guides the air toward the first side S1, the third port 13131 can guide the air toward the other side of the second axis L2 that is relatively far away from the second port 13111, that is, at this time, the first port 13121 and the second port 13111 can guide the air toward different sides respectively. Because the first shell 1311 and the second shell 1313 are arranged relative to each other in a direction perpendicular to the first axis L1 and the axis of the opening 112, the two can respectively discharge air in different directions. Therefore, under the premise that the size of a single air outlet is limited, the first shell 1311 and the second shell 1313 work together to achieve a wider range of air discharge. It should be noted that, as needed, the above-mentioned rotation ranges can be satisfied simultaneously, that is, while the second port 13111 exports airflow toward the first side S1, the third port 13131 can export airflow toward both the third side S3 and the fourth side S4.

[0083] Another description method can be used to describe the embodiments of the above-mentioned various rotation ranges, and correspond to the extreme positions of the first shell 1311 and the second shell 1313. Specifically, in addition to the first extreme position of the first shell 1311 rotating around the first axis L1 and the corresponding first direction X, similarly, the second shell 1313 can have a third extreme position and a fourth extreme position rotating around the second axis L2. When the second shell 1313 is at the third extreme position, the axial direction of the third port 13131 can be the third direction. When the second shell 1313 is at the fourth extreme position, the axial direction of the third port 13131 can be the fourth direction. In addition, see Figure 6, for each side of the axis, it can also be expressed as: along the direction perpendicular to the first axis L1 and the axis of the opening 112, the first axis L1 has a relative first side S1 and a second side S2, and the second axis L2 has a relative third side S3 and a fourth side S4, wherein the second side S2 and the third side S3 are located between the first side S1 and the fourth side S4.

[0084] See also Figure 6 Based on the above definition, the embodiment corresponding to the first rotation range described in the above embodiments can be expressed as the second port 13111 being suitable for exporting airflow along the first direction X toward the first side S1, and the third port 13131 being suitable for exporting airflow along the third direction toward the third side S3; the embodiment corresponding to the second rotation range described in the above embodiments can be expressed as the second port 13111 being suitable for exporting airflow along the first direction X toward the first side S1, and the third port 13131 being suitable for exporting airflow along the fourth direction toward the fourth side S4.

[0085] In order to meet the requirements of wind guide and connection of wind guide assembly 130, the structure of wind guide assembly 130 can be configured accordingly. Figure 8 In some embodiments, the first shell portion 1311 may have a first curved surface 13112. The housing 110 may have an inner sidewall 113. The first shell portion 1311 has a first rotation center 13113 about the first axis L1 and a first extreme position. Thus, when the first shell portion 1311 is in the first extreme position, the first curved surface 13112 may be at least partially located between the inner sidewall 113 and the first rotation center 13113 in a direction perpendicular to the first axis L1 and the axis of the opening 112. It is understood that the first curved surface 13112 may be the wall surface of the first shell portion 1311 near the air outlet side. When the first shell portion 1311 is in the first extreme position, the first curved surface 13112 may oppose the inner sidewall 113 of the housing 110 to prevent interference between the first shell portion 1311 and the inner sidewall 113. This arrangement can reduce the distance between the first shell portion 1311 and the inner sidewall 113, thereby meeting the requirements of a compact design.

[0086] For an embodiment in which the annular shell 131 includes a first shell portion 1311 and a second shell portion 1313, see Figure 6In some embodiments, the first shell portion 1311 may have a first curved surface 13112, and the second shell portion 1313 may have a second curved surface 13132. According to the requirements, the first curved surface 13112 or the second curved surface 13132 may be a uniform curved surface (a curved surface with uniform curvature at each point) or an uneven curved surface (a curved surface with uneven curvature at each point). In addition, for the convenience of description, it is defined that the first circumferential direction R1 surrounds the second axis L2, and the second circumferential direction R2 surrounds the second axis L2, and the first circumferential direction R1 is in opposite directions to the second circumferential direction R2. Based on the above definition, see Figure 6 The first shell portion 1311 may have a first rotation center 13113 and a first extreme position along the first circumferential direction R1, and the second shell portion 1313 may have a second rotation center 13133 and a third extreme position along the second circumferential direction R2. Since the first circumferential direction R1 and the second circumferential direction R2 are in opposite directions, the first extreme position and the third extreme position correspond to the positions where the angle between the first shell portion 1311 and the second shell portion 1313 reaches its maximum (also corresponding to the extreme air outlet range). Furthermore, the first rotation center 13113 may be located inside or outside the first shell portion 1311, and the second rotation center 13133 may be arranged similarly.

[0087] For details on the functions of the first curved surface 13112 and the second curved surface 13132, see Figure 6In some embodiments, when the first shell portion 1311 is in the first extreme position and the second shell portion 1313 is in the third extreme position, along a direction perpendicular to the first axis L1 and the axis of the opening 112, the first curved surface 13112 and the second curved surface 13132 may both be at least partially located between the first rotation center 13113 and the second rotation center 13133, and the arc center of the first curved surface 13112 may be located on the side of the first curved surface 13112 facing away from the second curved surface 13132, while the arc center of the second curved surface 13132 may be located on the side of the second curved surface 13132 facing away from the first curved surface 13112. The above-mentioned setting of the arc center positions indicates that in this type of embodiment, the first curved surface 13112 and the second curved surface 13132 are both curved surfaces with uniform curvature at all points. In addition, it can be understood that since the first curved surface 13112 and the second curved surface 13132 can be at least partially located between the first rotation center 13113 and the second rotation center 13133, it means that along the horizontal direction (i.e., the direction perpendicular to the first axis L1 and the axis of the opening 112), the side wall of the first shell 1311 close to the second shell 1313 is the first curved surface 13112, and the side wall of the second shell 1313 close to the first shell 1311 is the second curved surface 13132, and the first curved surface 13112 is opposite to the second curved surface 13132. It is easy to know from the description of the above-mentioned embodiments that when the first shell 1311 and the second shell 1313 rotate relative to each other, if the first shell 1311 and the second shell 1313 are larger in size or closer in distance, rotation interference is likely to occur, and if the distance between the first shell 1311 and the second shell 1313 is increased, it is easy to cause air leakage in the middle area (since the first shell 1311 and the second shell 1313 are both movable structures, even if a windshield structure is set between the two, it is still easy to leak air). Therefore, the above-mentioned setting of the first curved surface 13112 and the second curved surface 13132 can make the distance between the first shell 1311 and the second shell 1313 be closer when the first shell 1311 and the second shell 1313 rotate relative to each other without interference, so as to reduce air leakage between the two and meet the compact design requirements.

[0088] Furthermore, in order to avoid air leakage in the area between the first shell 1311 and the second shell 1313, in some embodiments, the air supply device 100 may also include a wind shield, which can be connected to the outer shell 110 and can block the gap between the first shell 1311 and the second shell 1313 to reduce air leakage.

[0089] In addition, in order to enable the first shell 1311 or the second shell 1313 to rotate, the air supply device 100 may further include a drive assembly 140. In some embodiments, the drive assembly 140 can simultaneously control the joint rotation of the two, that is, the drive assembly 140 can be configured to drive the first shell 1311 and the second shell 1313 to rotate synchronously relative to the housing 110. Thus, the air output volume and air output distribution can be more uniform by controlling the synchronous rotation of the two. In other embodiments, the drive assembly 140 can be configured to separately control the rotation angle of the first shell 1311 around the first axis L1 and the rotation angle of the second shell 1313 around the second axis L2. Thus, the decoupling of the rotation angles of the first shell 1311 and the second shell 1313 can be used to meet different user needs and achieve multi-dimensional customized comfortable air supply. It should be noted that in order to meet diverse control needs, the drive assembly 140 can integrate the above two control modes, that is, it can control the synchronous rotation of the first shell 1311 and the second shell 1313, and can also control the rotation of the two separately. In addition, according to user needs, the driving component 140 can also realize automatic cruising air supply and fixed angle air supply by controlling the first shell 1311 and the second shell 1313.

[0090] As can be seen from the description of the above embodiments, the air supply device 100 of the present invention can adjust the direction of the air flow from the second port 13111 by rotating the second port 13111, and the third port 13131 is also the same. Therefore, in order to further expand the air supply area, see Figure 3-Figure 4 In some embodiments, the first shell portion 1311 can be configured such that, during rotation about the first axis L1, the end of the first shell portion 13111 that is closer to the second port 13111 along the axis of the second port 13111 can extend out of the first cavity 111 through the opening 112. It will be appreciated that the end of the first shell portion 1311 that is closer to the second port 13111 along the axis of the second port 13111 is the end of the first shell portion 1311 that is suitable for directing airflow. Thus, during rotation, the first shell portion 1311 can initially be at least partially located within the first cavity 111. As the first shell portion 1311 rotates, the portion located within the first cavity 111 can gradually extend out of the first cavity 111. Compared to a configuration in which the entire first shell portion 1311 is located within the first cavity 111, this configuration prevents the housing 110 or other structures from blocking the airflow, thereby expanding the airflow range. Furthermore, because the extended portion of the first shell portion 1311 can be retracted into the first cavity 111, the air supply device 100 is easily stored. The extension setting of the first shell portion 1311 in this embodiment can also be applied to the second shell portion 1313, and will not be repeated here.

[0091] In addition, in other embodiments, the annular shell 131 can be configured so that one end extends out of the first cavity 111 from the opening 112, so that the first shell portion 1311 can be located outside the first cavity 111 from the beginning of rotation to the end of rotation, and can also have the effect of expanding the air outlet range.

[0092] See also Figure 3-Figure 7 In some embodiments, the annular shell 131 may further include a tube 1314 connected to the first shell portion 1311. The tube 1314 may be arranged opposite the first shell portion 1311 along a direction parallel to the axis of the opening 112. The end of the tube 1314 facing away from the first shell portion 1311 may have a first port 13121, and the other end may be connected to a second port 13111. It will be appreciated that the tube 1314 and the first shell portion 1311 may be arranged opposite each other along the direction of airflow, so that the airflow can be guided along the tube 1314 to the first shell portion 1311. Thus, the tube 1314 can effectively guide the airflow.

[0093] Based on the above-mentioned tube body 1314, in order to facilitate the first shell 1311 to rotate relative to the housing 110 around the first axis L1, the first shell 1311 can be driven to rotate by driving the tube body 1314. Figure 3-Figure 7 In the first embodiment of the rotation method, the tube body 1314 can be a bellows-type expansion and contraction tube that can fold or unfold, allowing the first shell portion 1311 to rotate relative to the outer shell 110. It is understood that the bellows-type expansion and contraction tube comprises foldable corrugated sheets that are connected along the folding and stretching direction to form a tubular shape. This structure provides the bellows with excellent elasticity and flexibility. The bellows-type expansion and contraction tube can be made of any suitable material as needed. Leveraging the properties of the bellows-type expansion and contraction tube, the tube body 1314 can be driven to expand when the airflow range needs to be expanded. When air is directed forward or needs to be stored, the tube body 1314 can be folded within the first cavity 111. This allows for the same external dimensions and packaging as a conventional air conditioner, eliminating the need for specialized packaging and preventing loss of container capacity during transportation. In the second embodiment of the rotation method, the tube body 1314 is elastic, allowing the first shell portion 1311 to rotate relative to the outer shell 110. It is understood that the tube body 1314 can achieve rotation through its own elastic deformation. Therefore, in some embodiments, the tube 1314 can be made of a material with good deformability, such as rubber or silicone. In conjunction with the previous embodiment, the tube 1314 can be a bellows-type expansion tube and also have elasticity to facilitate deformation. In an embodiment of the third rotation method, the tube 1314 (or the annular shell 131) can be connected to a rotating shaft. The rotation of the rotating shaft drives the first shell portion 1311 to rotate relative to the outer shell 110.

[0094] For the above-mentioned various embodiments of the rotation mode, the drive assembly 140 can be configured differently. Figure 9 In some embodiments, when the tube body 1314 is a bellows telescopic tube, the first shell 1311 / the second shell 1313 (or the tube body 1314) can be connected to the rotating shaft to facilitate the rotation of the first shell 1311 / the second shell 1313 (or the tube body 1314). Specifically, the drive assembly 140 may include a rotating shaft and a pushing device. Thus, in some embodiments, the tube body 1314 can be sleeved on the rotating shaft, and the pushing device is configured to push the tube body 1314, so that the tube body 1314 can rotate around the rotating shaft (the axis of the rotating shaft corresponds to the first axis L1 at this time), that is, it can rotate relative to the outer shell 110. When the tube body 1314 is elastic, the above-mentioned driving method can also be adopted. At this time, the pushing device can apply a force to the tube body 1314 to cause the tube body 1314 to undergo elastic deformation and rotate relative to the outer shell 110. For details, see Figure 9 In some embodiments, the aforementioned driving device may be a screw transmission mechanism, that is, a motor may be used to drive a screw to rotate, thereby driving a connecting member to translate. The connecting member is connected to the first shell 1311 / second shell 1313 (or tube 1314), and the translation of the connecting member may be used to drive the first shell 1311 / second shell 1313 (or tube 1314), so that the first shell 1311 can rotate relative to the housing 110 about the first axis L1. Similarly, in other embodiments, the first shell 1311 / second shell 1313 (or tube 1314) can be driven by the expansion and contraction of the output end of the driving member, wherein the driving member may be one of a motor, a hydraulic lever, an electric cylinder, and a pneumatic cylinder.

[0095] For example, the following describes a specific driving method corresponding to a specific embodiment. Figure 3-Figure 5 as well as Figure 9In some embodiments, the first shell 1311 and the second shell 1313 are each connected to a tube body 1314, and the tube body 1314 is a corrugated telescopic tube. Along the direction perpendicular to the first axis L1 and the axis of the opening 112, the ends of the two tube bodies 1314 facing away from each other are each provided with a rotating shaft (that is, the two rotating shafts are respectively provided at the two ends of the outer side). The driving assembly 140 includes a screw mechanism, which is connected to the rear side of the air supply device 100 away from the second port 13111 and the third port 13131, and the screw in the screw mechanism extends from the back to the front (corresponding to the axial direction of the opening 112). Therefore, the motor in the screw mechanism can drive the screw to rotate, and then drive the connecting member to move in a translational manner. The connecting member pushes the first shell 1311 / the second shell 1313 (or the tube body 1314) away from one end of the rotating shaft. Two groups of screw mechanisms can be provided to drive the first shell 1311 and the second shell 1313 respectively. Thus, according to the above arrangement, the screw mechanism can drive the first shell 1311 to rotate relative to the housing 110 around the first axis L1, and drive the second shell 1313 to rotate relative to the housing 110 around the second axis L2. In other words, the screw mechanism screw consumes the rotational motion while ensuring that the connecting member is moving forward, thereby causing the annular shell 131 to only move forward in a plane, rather than rotating. The motor can use a fixed shaft to fix the position of the motor, and at the same time cooperate with the motor's rotating shaft to ensure that the motor can adaptively rotate following the angle change of the screw. When the air outlet needs to be extended, the motor will rotate accordingly, driving the screw to rotate and move forward. The rotation and forward motion of the screw are transmitted to the connecting member, wherein the connecting member is a rotating connecting rod, which only transmits the forward motion to the annular shell 131. The annular shell 131 is restricted by the rotating axis on the side and can only rotate around the rotating axis as the center, while driving the expansion and contraction of the tube body 1314, thereby driving the deflection of the angle of the entire component. At this time, the motor makes corresponding angle adjustments through the motor fixed axis and the motor rotating axis. Ultimately, the two air outlets can be independently controlled to rotate out and retract and hide, thereby controlling the air outlet direction.

[0096] In addition, in other embodiments, a cam drive can be used to enable the tube 1314 to achieve telescopic movement relative to the opening 112, thereby achieving rotation of the first shell 1311 or the second shell 1313. Specifically, in some embodiments, the drive assembly 140 may include a cam and a rotating shaft connected to the cam, with the cam abutting against the end of the tube 1314 facing away from the second end 13111. Thus, the tube 1314 can be driven to rotate to achieve telescopic movement. Specifically, when the protruding end of the cam abuts against the first shell 1311 / second shell 1313 (or the tube 1314), the extension distance of the tube 1314 reaches a maximum value, and when the recessed end of the cam abuts against the first shell 1311 / second shell 1313 (or the tube 1314), the extension distance of the tube 1314 reaches a minimum value. The above is a configuration for driving the first shell 1311 to rotate, and the configuration for driving the second shell 1313 to rotate is similar.

[0097] At the same time, in some embodiments, various settings that allow the tube body 1314 to be telescopic (including settings in which the tube body 1314 is a corrugated telescopic tube and settings in which the tube body 1314 is elastic) can also achieve a larger air supply angle and air supply range by extending the length of the tube body 1314.

[0098] In addition, in other embodiments, the tube body 1314 can be driven to rotate only by the rotation of the rotating shaft, that is, the tube body 1314 can be fixedly connected to the rotating shaft, and the driving component 140 drives the rotating shaft to rotate while driving the tube body 1314 to rotate relative to the shell 110.

[0099] At the same time, the shape of the first shell 1311 will affect the direction of the airflow and the space required for the first shell 1311 to rotate. Therefore, according to different needs, in some embodiments, when observed in a direction parallel to the first axis L1, the first shell 1311 can be rectangular, fan-shaped, fan-shaped, or circular.

[0100] In addition, when the rotation axis is located at different positions, the rotation form of the first shell portion 1311 will also be different accordingly. In some embodiments, along the direction parallel to the axis of the opening 112, the rotation axis can be located on the side of the center of gravity of the annular shell 131 away from the second port 13111; or in other embodiments, along the direction parallel to the axis of the opening 112, the rotation axis can be located on the side of the center of gravity of the annular shell 131 close to the second port 13111. It can be understood that the above two types of embodiments respectively indicate that the rotation axis can be located at the end of the annular shell 131 away from the air outlet and the rotation axis can be located at the end of the annular shell 131 close to the air outlet. In addition, in combination with the above embodiments, when the annular shell 131 includes a first shell portion 1311 and a second shell portion 1313 relative to each other, the first shell portion 1311 can be connected to the first rotation axis, the second shell portion 1313 can be connected to the second rotation axis, and in order to meet different air outlet requirements, see. Figure 3-Figure 5 as well as Figure 9 In some embodiments, in the transverse direction (a direction perpendicular to the first axis L1 and the axis of the opening 112), the first rotation axis can be connected to the side of the first shell portion 1311 facing away from the second shell portion 1313, and the second rotation axis can be connected to the side of the second shell portion 1313 facing away from the first shell portion 1311. In this case, when the first shell portion 1311 and the second shell portion 1313 rotate, they can respectively discharge air to two sides, so that the air discharge of both can cover a larger area; see Figure 6 In other embodiments, along the horizontal direction (perpendicular to the first axis L1 and the axis of the opening 112), the first rotating shaft can be connected to the side of the first shell 1311 close to the second shell 1313, and the second rotating shaft can be connected to the side of the second shell 1313 close to the first shell. At this time, when the first shell 1311 and the second shell 1313 rotate, they can both discharge air toward the inside (the area between the first shell 1311 and the second shell 1313), so that the airflow can be more concentrated and the wind force is stronger.

[0101] In addition to adjusting the airflow direction by rotating the first shell 1311 or the second shell 1313, in order to meet the needs of adjusting the wind direction in more directions, see Figure 3-Figure 5 as well as Figure 9 In some embodiments, the first shell portion 1311 may include an air guide plate 13114. Specifically, the air guide plate 13114 may be used to define the second port 13111, and the air guide plate 13114 may be configured to be rotatable around the third axis L3 relative to the housing 110. The first axis L1, the axis of the opening 112, and the third axis L3 intersect with each other. It is understandable that the air guide plate 13114 can, on the one hand, guide the airflow derived from the second port 13111. Therefore, according to requirements, the air guide plate 13114 can be provided as a single piece or multiple pieces. For example, see Figure 3-Figure 5as well as Figure 9 In some embodiments, the air deflectors 13114 may be a plurality of rectangular plates arranged at intervals. Depending on the desired air flow, the air deflectors 13114 may also have other shapes or arrangements, which will not be described in detail here. Furthermore, the air deflectors 13114 may rotate about the third axis L3 to further adjust the airflow direction. For ease of description, the following description uses an embodiment in which the third axis L3 is perpendicular to both the first axis L1 and the axis of the opening 112. Different embodiments may be combined with different technical solutions.

[0102] In addition, in some embodiments, the first axis L1 can be arranged in the vertical direction, and at the same time, the first shell 1311 can also be configured to rotate around a fourth axis relative to the housing 110, wherein the fourth axis is arranged in the horizontal direction. It is understood that the first shell 1311 can achieve air supply at different angles in the horizontal direction by rotating around the first axis L1, and can also achieve air supply at different angles in the vertical direction by rotating around the fourth axis. In combination with the setting of the air deflector 13114, the drive assembly 140 can be configured to drive the air deflector 13114 to rotate simultaneously with the first shell 1311 / the second shell 1313, or can independently control the rotation of the air deflector 13114 and the rotation of the first shell 1311 / the second shell 1313.

[0103] In addition, in order to make the air flow effect better, see Figure 3-Figure 5 as well as Figure 9 In some embodiments, the air inlet of the air supply assembly 120 can be located on any wall of the outer shell 110 except the plane where the opening 112 is located (corresponding to the air outlet side), and half of the area of ​​the wall can be the rear return air intake grille, thereby increasing the air intake area, increasing the air volume, and improving the heat exchange efficiency.

[0104] The embodiment of the second aspect of the present invention further provides an air handling unit, which includes the air supply device 100 of any of the above embodiments.
