Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air guiding structure, an indoor air conditioning unit having the air guiding structure, and an air conditioning system having the indoor air conditioning unit. Background Technology

[0002] An air conditioning system is a system that uses artificial methods to control the temperature, humidity, cleanliness, and airflow speed of indoor air. It can provide certain places with air of a certain temperature, humidity, and air quality to meet the requirements of users and production processes and improve occupational health and indoor climate conditions.

[0003] To achieve longer-distance and multi-directional air delivery, the air conditioning system is equipped with an air guide structure at the air outlet of its indoor unit. This structure adjusts the air delivery direction of the indoor unit, thereby improving the comfort of the air delivery.

[0004] However, existing air guiding structures mainly consist of air guide plates and drive mechanism control. The drive mechanism control can only control a single air guide plate to swing in the left-right direction or the up-down direction, so that a single air guide plate can only achieve air guiding function in two directions. It cannot control a single air guide plate to swing in both the left-right and up-down directions at the same time. As a result, the existing air guiding structure cannot achieve air guiding in more directions at the same time, which limits the adjustment range of air guiding direction and the air guiding flexibility. This limits the air supply flexibility of the air conditioner and thus affects the user's comfort. Summary of the Invention

[0005] To achieve the primary objective of this invention, this invention provides an air guide structure capable of controlling a single air guide plate to achieve air guiding functions in four directions, thereby greatly expanding the adjustment range of the air guiding direction and improving the flexibility of air guiding direction control, thereby enhancing the air supply flexibility of the air conditioner and improving the user's comfort.

[0006] To achieve the second objective of this utility model, this utility model provides an indoor air conditioning unit having the above-mentioned air guiding structure.

[0007] To achieve the third objective of this utility model, this utility model provides an air conditioning system having the above-mentioned indoor air conditioning unit.

[0008] To achieve the first objective of this utility model, this utility model provides an air guiding structure for installation at the air outlet of an indoor air conditioning unit. The structure includes an air guiding assembly comprising an air guiding plate, a first driving mechanism, a first rotating shaft, a linkage rod, a second driving mechanism, and a second rotating shaft. The first rotating shaft extends in a first direction, and the first driving mechanism controls the first rotating shaft to rotate around the first direction. The first end of the linkage rod is fixedly connected to the first rotating shaft, and the second end of the linkage rod is rotatably hinged to the air guiding plate around a second direction. The second rotating shaft extends in a second direction, and the second driving mechanism controls the second rotating shaft to rotate around the second direction. The air guiding plate is fixedly connected to the second rotating shaft, and the second direction is perpendicular to the first direction.

[0009] As can be seen from the above scheme, during the air guiding operation of the air guiding structure of this utility model, the first drive mechanism controls the first rotating shaft to rotate around the first direction. Since the first end of the linkage rod is fixedly connected to the first rotating shaft, and the second end of the linkage rod is hinged to the air guide plate around the second direction, the linkage rod is driven to rotate around the first direction simultaneously to drive the air guide plate to rotate around the first direction, thereby controlling the air guide plate to achieve the air guiding function on both sides of the first direction. The second drive mechanism controls the second rotating shaft to rotate around the second direction. Since the air guide plate is fixedly connected to the second rotating shaft, the air guide plate is driven to rotate around the second direction simultaneously to control the air guide plate to achieve the air guiding function on both sides of the second direction. This allows a single air guide plate to achieve air guiding functions in four directions, and the air guide plate can be flexibly adjusted according to actual needs to achieve air guiding functions in each direction, thereby improving the air supply flexibility of the air conditioner and improving the user's comfort.

[0010] Therefore, the air guide structure of this utility model can control a single air guide plate to achieve air guiding function in four directions, thereby greatly expanding the adjustment range of the air guiding direction and improving the flexibility of air guiding direction control, thereby improving the air supply flexibility of the air conditioner and improving the user's comfort.

[0011] A further solution is to install two limiting plates on the back of the air guide plate, with the two limiting plates arranged side by side in the second direction, and the second end of the linkage rod located between the two limiting plates.

[0012] A further proposed solution is to insert the drive end of the second rotating shaft into two limiting plates, and to rotatably mount the second end of the linkage rod onto the drive end of the second rotating shaft.

[0013] A further embodiment is that the second rotating shaft includes a control rod segment, a drive rod segment, and a balance rod segment connected in sequence. The drive rod segment is inserted into two limit plates, and the control rod segment and the balance rod segment are located on the outside of the two limit plates in the second direction, respectively. The control rod segment is connected to the second drive mechanism.

[0014] A further embodiment is that the first drive mechanism includes a first motor, a first crank, a linkage plate, and a second crank. The first end of the first crank is connected to the drive shaft of the first motor, and the second end of the first crank is rotatably hinged to one end of the linkage plate to control the linkage plate to move in a second direction. The first end of the second crank is rotatably hinged to the linkage plate, and the second end of the second crank is fixedly connected to the control end of the first rotating shaft.

[0015] A further embodiment is that each air guide assembly contains at least two air guide plates, linkage rods, and second rotating shafts. Multiple air guide plates are arranged in a first direction, the first ends of multiple linkage rods are fixedly connected to the first rotating shaft and arranged in the first direction, and the second end of one linkage rod is rotatably hinged to an air guide plate around a second direction. One air guide plate is fixedly connected to one second rotating shaft, and the second drive mechanism synchronously controls the rotation of multiple second rotating shafts.

[0016] A further embodiment is that the second drive mechanism includes a second motor, a third crank, a connecting rod, and multiple fourth cranks. The first end of the third crank is connected to the drive shaft of the second motor, and the second end of the third crank is rotatably hinged to one end of the connecting rod to control the movement of the connecting rod in a first direction. The first end of one fourth crank is rotatably hinged to the connecting rod, and the second end of one fourth crank is fixedly connected to the control end of a second rotating shaft.

[0017] A further option is to have multiple air guide components, which are arranged in a first direction and / or a second direction.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0035] See Figures 1 to 9 This embodiment discloses an air conditioner indoor unit 10, including an air outlet 121 and an air guide structure 13. The air guide structure 13 is disposed at the air outlet 121 of the air conditioner indoor unit 10. Specifically, the air outlet 121 is provided on the housing 11 of the air conditioner indoor unit 10 in this embodiment. The housing 11 is mainly composed of a top cover, an air outlet frame 12, a decorative panel, and a chassis. The air outlet frame 12 is the air circulation outlet position of the air conditioner indoor unit 10, and the air outlet 121 is located on the air outlet frame 12. Thus, the air guide structure 13 in this embodiment is supported on the air outlet frame 12 and located at the air outlet 121 to control the air supply direction.

[0036] In this embodiment, the air guiding structure 13 includes an air guiding assembly 131, which includes an air guiding plate 1311, a first driving mechanism, a first rotating shaft 13112, a linkage rod 13113, a second driving mechanism, and a second rotating shaft 13110. The first rotating shaft 13112 extends in a first direction, and the first driving mechanism controls the first rotating shaft 13112 to rotate around the first direction. The first end of the linkage rod 13113 is fixedly connected to the first rotating shaft 13112, and the second end of the linkage rod 13113 is hinged to the air guiding plate 1311 around a second direction. The second rotating shaft 13110 extends in a second direction, and the second driving mechanism controls the second rotating shaft 13110 to rotate around the second direction. The air guiding plate 1311 is fixedly connected to the second rotating shaft 13110, and the second direction is perpendicular to the first direction.

[0037] See Figure 10In this embodiment, during the air guiding operation of the air guiding structure 13, the first drive mechanism controls the first rotating shaft 13112 to rotate around the first direction. Since the first end of the linkage rod 13113 is fixedly connected to the first rotating shaft 13112, and the second end of the linkage rod 13113 is hinged to the air guiding plate 1311 around the second direction, the linkage rod 13113 is driven to rotate around the first direction to drive the air guiding plate 1311 to rotate around the first direction, so as to control the air guiding plate 1311 to achieve the air guiding function around both sides of the first direction. The second drive mechanism controls the second rotating shaft 13110 to rotate around the second direction. Since the air guiding plate 1311 is fixedly connected to the second rotating shaft 13110, the air guiding plate 1311 is driven to rotate around the second direction, so as to control the air guiding plate 1311 to achieve the air guiding function around both sides of the second direction, so that a single air guiding plate 1311 can achieve the air guiding function in four directions.

[0038] Specifically, in this embodiment, the indoor unit 10 of the air conditioner is a vertical indoor unit, so the first direction is the vertical direction and the second direction is the horizontal direction. This enables the single air guide plate 1311 to rotate simultaneously in the left-right and up-down directions, thereby controlling the single air guide plate 1311 to achieve air guiding functions in four directions: up, down, left, and right. It can also flexibly adjust the air guide plate 1311 to achieve air guiding functions in four directions: up, down, left, and right according to actual needs, so as to improve the air supply flexibility of the air conditioner and thus improve the user's comfort.

[0039] Therefore, the air guide structure 13 in this embodiment can control a single air guide plate 1311 to achieve air guiding function in four directions, thereby greatly expanding the adjustment range of the air guiding direction and improving the flexibility of air guiding direction control, thereby improving the air supply flexibility of the air conditioner and improving the user's comfort.

[0040] To ensure that the first drive mechanism can drive the air guide plate 1311 to rotate synchronously around the first direction when controlling the first rotating shaft 13112 to rotate around the first direction, in this embodiment, two limiting plates 13114 are provided on the back of the air guide plate 1311. The two limiting plates 13114 are arranged side by side in the second direction, and the second end of the linkage rod 13113 is located between the two limiting plates 13114, thereby restricting the movement of the second end of the linkage rod 13113 relative to the air guide plate 1311 in the second direction. This ensures that the movement of the second end of the linkage rod 13113 relative to the air guide plate 1311 is only a rotation around the second direction, hinged to the air guide plate 1311, thereby improving the control synchronicity, accuracy, stability and reliability of the air guide plate 1311 rotating around the first direction.

[0041] Specifically, in this embodiment, the drive end of the second rotating shaft 13110 is inserted into two limiting plates 13114, and the second end of the linkage rod 13113 is rotatably sleeved on the drive end of the second rotating shaft 13110. This ensures that when the second drive mechanism controls the second rotating shaft 13110 to rotate around the second direction to synchronously drive the air guide plate 1311 to rotate around the second direction, it will not cause any linkage control to the linkage rod 13113, thereby improving the rotation control flexibility of the air guide plate 1311.

[0042] To prevent the air guide plate 1311 from becoming unbalanced when rotating around the second direction, the second rotating shaft 13110 in this embodiment includes a control rod segment, a drive rod segment, and a balance rod segment connected in sequence. The drive rod segment of the second rotating shaft 13110 is inserted into the two limiting plates 13114. The second end of the linkage rod 13113 is rotatably sleeved on the drive rod segment of the second rotating shaft 13110. The control rod segment of the second rotating shaft 13110 and the balance rod segment 13111 of the second rotating shaft 13110 are respectively located outside the two limiting plates 13114 in the second direction, and the control rod segment of the second rotating shaft 13110 is connected to the second drive mechanism.

[0043] In this embodiment, the first drive mechanism includes a first motor 1312, a first crank 1313, a linkage plate 1314, and a second crank 1315. The first end of the first crank 1313 is connected to the drive shaft of the first motor 1312, and the second end of the first crank 1313 is rotatably hinged to one end of the linkage plate 1314 to control the linkage plate 1314 to move in the second direction. The first end of the second crank 1315 is rotatably hinged to the linkage plate 1314, and the second end of the second crank 1315 is fixedly connected to the control end of the first rotating shaft 13112.

[0044] Therefore, during the air guiding operation of the air guiding structure 13 in this embodiment, when the drive shaft of the first motor 1312 controls the rotation of the first crank 1313, the second end of the first crank 1313, which is hinged to the linkage plate 1314, moves in an arc around the drive shaft of the first motor 1312, thereby controlling the linkage plate 1314 to move in the second direction. As the linkage plate 1314 moves in the second direction, it synchronously drives the first end of the second crank 1315 to move in the second direction. Since the second end of the second crank 1315 is fixedly connected to the control end of the first rotating shaft 13112... This causes the first end of the second crank 1315 to make an arc motion around the first rotating shaft 13112, thereby driving the second end of the second crank 1315 to rotate the first rotating shaft 13112 around the first direction. Since the first end of the linkage rod 13113 is fixedly connected to the first rotating shaft 13112, and the second end of the linkage rod 13113 is hinged to the air guide plate 1311 around the second direction, the linkage rod 13113 is synchronously driven to rotate around the first direction to drive the air guide plate 1311 to rotate around the first direction, so as to control the air guide plate 1311 to achieve the air guiding function on both sides around the first direction.

[0045] To further improve the air guiding effect, in this embodiment, each air guiding assembly 131 has at least two air guiding plates 1311, linkage rods 13113, and second rotating shafts 13110. Multiple air guiding plates 1311 are arranged in the first direction. The first ends of multiple linkage rods 13113 are respectively fixedly connected to the first rotating shaft 13112 and arranged in the first direction. The second end of one linkage rod 13113 is rotatably hinged to an air guiding plate 1311 around the second direction. One air guiding plate 1311 is fixedly connected to one second rotating shaft 13110. The second drive mechanism synchronously controls the rotation of multiple second rotating shafts 13110.

[0046] Furthermore, the second drive mechanism in this embodiment includes a second motor 1316, a third crank 1317, a connecting rod 1318, and a plurality of fourth cranks 1319. The first end of the third crank 1317 is connected to the drive shaft of the second motor 1316, and the second end of the third crank 1317 is rotatably hinged to one end of the connecting rod 1318 to control the connecting rod 1318 to move in a first direction. The first end of a fourth crank 1319 is rotatably hinged to the connecting rod 1318, and the second end of a fourth crank 1319 is fixedly connected to the control end of a second rotating shaft 13110.

[0047] Therefore, during the air guiding operation of the air guiding structure 13 in this embodiment, when the drive shaft of the second motor 1316 controls the rotation of the third crank 1317, the second end of the third crank 1317, which is rotatably hinged to the connecting rod 1318, moves in an arc around the drive shaft of the second motor 1316, thereby controlling the connecting rod 1318 to move in the first direction. As the connecting rod 1318 moves in the first direction, the first end of the fourth crank 1319 moves in the first direction simultaneously. The second end of the fourth crank 1319 is fixedly connected to the control end of the second rotating shaft 13110, so that the first end of the fourth crank 1319 moves in an arc around the second rotating shaft 13110. Thus, the second end of the fourth crank 1319 drives the second rotating shaft 13110 to rotate in the second direction. Since the air guide plate 1311 is fixedly connected to the second rotating shaft 13110, the air guide plate 1311 is synchronously driven to rotate in the second direction, so as to control the air guide plate 1311 to achieve the air guiding function on both sides of the second direction.

[0048] Furthermore, in this embodiment, the air guiding structure 13 can simultaneously control multiple air guiding plates 1311 in a group of air guiding components 131 to rotate synchronously around the second direction through a second motor 1316, and can simultaneously control multiple air guiding plates 1311 in a group of air guiding components 131 to rotate synchronously around the first direction through a first motor 1312. This not only simplifies the structure and reduces the number of driving mechanisms, but also improves the flexibility and response speed of control, and reduces energy consumption.

[0049] Furthermore, in this embodiment, the air guiding structure 13 has multiple air guiding components 131, which are arranged in a first direction and / or a second direction. This allows the multiple air guiding components 131 to be modularly arranged at the air outlet 121. Users can flexibly adjust the air guiding direction of each air guiding component 131 according to actual needs, further optimizing the air supply effect of the air conditioning indoor unit 10 and the user's comfort. Moreover, each air guiding component 131 of the modular design can operate independently without affecting each other. It can simultaneously deliver air to the left, right, up, and down at the air outlet 121, which can expand the air supply range and make the air supply evenly distributed throughout the room to avoid local overcooling or overheating.

[0050] Furthermore, in this embodiment, the air guide structure 13 modularly arranges multiple air guide components 131 at the air outlet 121. Therefore, when a certain part of the air guide plate 1311 is damaged, the user can disassemble and replace the damaged air guide component 131 separately without replacing the entire air guide structure 13, thereby reducing maintenance costs.

[0051] The above embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles of this utility model patent application should be included within the scope of this utility model patent application.
