Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically providing an air outlet guide device and an indoor unit. Background Technology

[0002] Currently, air conditioners have become an indispensable appliance in people's work and life, providing users with a comfortable living environment. Air conditioners are usually equipped with air guide vanes, which extend under the action of a guiding structure to a specific position, guiding the airflow direction of the indoor unit and meeting the user's needs for airflow comfort.

[0003] However, the motor that drives the air guide plate to swing up and down at the air outlet is located at the end of the guide structure. This means that the end of the guide structure has to bear the weight of both the air guide plate and the motor, resulting in a "top-heavy" problem. The overall layout is unreasonable and will also affect the stable operation of the air guide plate to some extent.

[0004] Moreover, the existing guide structure drives the air guide plate to extend out of the air outlet, which occupies a large space and has certain requirements for installation space, thus limiting the user's choices.

[0005] Accordingly, a new technical solution is needed in this field to solve the above-mentioned technical problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the unreasonable structural layout of the existing guide structure leads to the unstable operation of the air guide plate.

[0007] In a first aspect, the present invention provides a guiding device for an air outlet, the guiding device comprising a guiding assembly and an air guide plate, the guiding assembly comprising a fixing member, a first driving mechanism, a second driving mechanism, a first transmission mechanism, a second transmission mechanism, and a push rod; the fixing member is fixedly disposed relative to the air outlet, the first driving mechanism is fixedly disposed on the fixing member, the push rod is slidably disposed on the fixing member, the driving end of the first driving mechanism is connected to the push rod through the first transmission mechanism, and the push rod is connected to the air guide plate; the second driving mechanism is fixedly disposed on the fixing member, the second transmission mechanism comprises a first pulley, a second pulley, and a belt, the second driving mechanism... The drive end is connected to the first pulley, which is rotatably mounted on the fixed member. The second pulley is rotatably mounted on the push rod and connected to the air guide plate. The first pulley and the second pulley are connected by the belt. The first drive mechanism drives the first transmission mechanism to rotate in the forward direction, so as to drive the air guide plate to extend outward relative to the air outlet. Then the belt is in a tensioned state. The second drive mechanism drives the second transmission mechanism to drive the air guide plate to swing relative to the air outlet. The first drive mechanism drives the first transmission mechanism to rotate in the reverse direction, so as to drive the air guide plate to retract inward relative to the air outlet. Then the belt is in a slack state.

[0008] In a specific embodiment of the above-mentioned air outlet guide device, the first transmission mechanism includes a first gear, a second gear, and a rack that are meshed together in sequence. The first gear is connected to the drive end of the first drive mechanism. The first gear and the second gear are rotatably mounted on the fixed member, and the rack is fixedly mounted on the push rod.

[0009] In a specific embodiment of the above-mentioned air outlet guiding device, the rack is configured as an arc-shaped rack, so that the air guide plate extends outward or retracts inward along an arc-shaped path relative to the air outlet.

[0010] In a specific embodiment of the above-mentioned air outlet guide device, the first transmission mechanism includes a cam, a first connecting rod, and a cylindrical pin. The cam is connected to the driving end of the first driving mechanism and is rotatably mounted on the fixed member. One end of the first connecting rod is rotatably connected to the push rod, and the other end of the first connecting rod is rotatably connected to the cylindrical pin. The cylindrical pin is in contact with the cam.

[0011] In a specific embodiment of the air outlet guide device described above, the first transmission mechanism further includes a second connecting rod, which is disposed between the push rod and the first connecting rod. One end of the second connecting rod is rotatably connected to the push rod, and the other end of the second connecting rod is rotatably connected to one end of the first connecting rod.

[0012] In a specific embodiment of the above-mentioned air outlet guiding device, the fixing member is further provided with a third guiding groove and a limiting groove that are interconnected, and the cylindrical pin is provided with a sliding post and a limiting post. The sliding post cooperates with the third guiding groove, and the limiting post cooperates with the limiting groove. When the air guide plate extends outward relative to the air outlet, the limiting post can slide into the limiting groove and cooperate with the limiting groove. When the air guide plate retracts inward relative to the air outlet, the limiting post can slide into the third guiding groove and cooperate with the third guiding groove.

[0013] In a specific embodiment of the above-mentioned air outlet guiding device, a first track module is provided on the push rod, and a second track module is provided on the fixing member. The first track module cooperates with the second track module; and / or the first track module includes a first drive column and a second drive column, and the second track module includes a first guide groove and a second guide groove. The first drive column cooperates with the first guide groove, and the second drive column cooperates with the second guide groove; and / or both the first guide groove and the second guide groove are set as arc-shaped grooves, so that the air guide plate extends outward or retracts inward along an arc-shaped path relative to the air outlet.

[0014] In a specific embodiment of the air outlet guide device described above, two sets of guide components are provided, and the two sets of guide components are symmetrically arranged on the left and right sides of the air guide plate.

[0015] In a second aspect, the present invention also provides an air conditioner, the air conditioner including an indoor unit, the indoor unit including the guide device as described above.

[0016] In a third aspect, the present invention also provides a multi-split air conditioner, the multi-split air conditioner comprising an outdoor unit connected to each other and a plurality of indoor units arranged in parallel, wherein the outdoor unit comprises one or more, and the indoor unit comprises the guiding device as described above.

[0017] With the above technical solution, the air guide plate, driven by the guide component, can extend outward or retract inward relative to the air outlet, and can also swing relative to the air outlet, thereby expanding the air supply range and air supply mode to meet user needs.

[0018] Furthermore, by setting the second drive mechanism on the fixed part and connecting it to the air guide plate through the second transmission mechanism, instead of directly connecting the second drive mechanism to the air guide plate, the load-bearing pressure at the end of the push rod is reduced, avoiding "top-heavy" structure. The structure layout is reasonable and can ensure that the air guide plate can be stably extended or retracted.

[0019] Furthermore, the guide assembly can achieve the extension or retraction of the air guide plate relative to the air outlet by means of only the structure of the first drive mechanism + the first transmission mechanism + the push rod. The structure is simple, highly practical and not easily damaged.

[0020] Furthermore, the air guide plate can extend outward or retract inward along an arc-shaped path. Compared to the existing air guide plates that flow straight in and out of the air outlet, by controlling the distance the air guide plate extends outward, its vertical angle can be adjusted to guide airflow, expand the air delivery range, and meet the needs of users for various air delivery modes. In addition, the space occupied by the extending or retracting air guide plate is relatively small, making efficient use of space. For example, using the above-mentioned guiding device on an indoor air conditioning unit, due to its arc-shaped movement path, can meet the needs of users whose indoor spaces are occupied by suspended ceilings.

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] It should be noted that in the description of this invention, terms such as "inner" that indicate direction or positional relationship are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the relevant device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Example 1

[0026] like Figure 1 and Figure 2 As shown, the present invention provides a guide device for an air outlet, including a guide assembly and an air guide plate 9. The guide assembly includes a fixing member 1, a first driving mechanism 2, a first transmission mechanism 3, and a push rod 4. The fixing member 1 is fixedly disposed relative to the air outlet, the first driving mechanism 2 is fixedly disposed on the fixing member 1, and the push rod 4 is slidably disposed on the fixing member 1. The driving end of the first driving mechanism 2 is connected to the push rod 4 through the first transmission mechanism 3. The push rod 4 is connected to the air guide plate 9. The first driving mechanism 2 drives the first transmission mechanism 3 to drive the push rod 4 to slide relative to the fixing member 1, thereby causing the air guide plate 9 to extend outward or retract inward relative to the air outlet.

[0027] Specifically, the first drive mechanism 2 uses a motor, and the fixing member 1 includes a first housing 11 and a second housing 12 that are fastened together. The first drive mechanism 2 is fixedly mounted on the first housing 11, and a cavity with a receiving space is formed between the first housing 11 and the second housing 12. The push rod 4 is mounted in the cavity and its end extends out of the cavity.

[0028] The advantage of the above structure is that the guide component can achieve the extension or retraction of the air guide plate 9 relative to the air outlet by means of the first drive mechanism 2 + the first transmission mechanism 3 + the push rod 4. The structure is simple, practical and not easily damaged.

[0029] like Figure 3 As shown, the first transmission mechanism 3 includes a first gear 31, a second gear 32, and a rack 33 that are meshed together. The first gear 31 is connected to the drive end of the first drive mechanism 2. The first gear 31 and the second gear 32 are rotatably mounted on the fixed member 1. The second gear 32 is meshed with the rack 33, and the rack 33 is fixedly mounted on the push rod 4. The first gear 31 and the second gear 32 are rotatably mounted on the first housing 11.

[0030] Specifically, the inner circumference of the push rod 4 is set as an arc-shaped surface, and the rack 33 is set as an arc-shaped rack 33, which is fixedly set on the inner circumference of the push rod 4. Of course, the inner circumference of the push rod 4 can also be set as a toothed structure that meshes with the second gear 32. The first drive mechanism 2 drives the second gear 32 to rotate in the forward direction, so as to drive the rack 33 to slide outward relative to the fixed member 1, thereby driving the air guide plate 9 to extend outward relative to the air outlet; the first drive mechanism 2 drives the second gear 32 to rotate in the reverse direction, so as to drive the rack 33 to slide inward relative to the fixed member 1, thereby driving the air guide plate 9 to retract inward relative to the air outlet.

[0031] It should be noted that although the above description combines two gears, this is not a limitation. Those skilled in the art can also provide one gear according to actual needs, and the above adjustments are within the protection scope of this invention.

[0032] like Figure 2 and Figure 3 As shown, a first track module 5 is provided on the push rod 4, and a second track module 6 is provided on the fixing member 1. The first track module 5 and the second track module 6 cooperate with each other. The first track module 5 includes a first drive post 51 and a second drive post 52, and the second track module 6 includes a first guide groove 61 and a second guide groove 62. The first drive post 51 cooperates with the first guide groove 61, and the second drive post 52 cooperates with the second guide groove 62.

[0033] Both the first guide groove 61 and the second guide groove 62 are arc-shaped grooves. The first guide groove 61 is located below the second guide groove 62. The arc length of the first guide groove 61 is less than the arc length of the second guide groove 62. Under the action of the rack 33 driving the arc-shaped gear, the air guide plate 9 extends outward from top to bottom or retracts inward from bottom to top along the arc-shaped path relative to the air outlet. It should be noted that the arc length and curvature of the first guide groove 61 and the second guide groove 62 are related to the arc length and curvature of the arc-shaped gear. Those skilled in the art need to set them according to the actual situation, as long as the air guide plate 9 can move along the arc-shaped path. In addition, it should be noted that although the above description is based on the movement of the air guide plate 9 along the arc-shaped path, it is not restrictive. Those skilled in the art can also push the push rod 4 along a straight path to push the air guide plate 9 outward or retract inward relative to the air outlet as needed, and the structure of the gear and guide groove will be changed accordingly. Preferably, the air guide plate 9 can move along the arc-shaped path.

[0034] The advantages of the above structure are that the air guide plate 9 can extend outward or retract inward along an arc-shaped path. Compared with the existing straight-in-straight path of the air guide plate 9 relative to the air outlet, by controlling the distance the air guide plate 9 extends outward, the angle of the air guide plate 9 in the vertical direction can be adjusted to guide the airflow, expand the air supply range, and meet the needs of users for various air supply modes. In addition, the space occupied by the extension or retraction of the air guide plate 9 is relatively small, making reasonable use of space. For example, when the above-mentioned guiding device is used on the indoor unit of an air conditioner, the arc-shaped movement path can meet the needs of users whose indoor space is occupied by suspended ceilings.

[0035] Furthermore, when the push rod 4 drives the air guide plate 9 to move relative to the air outlet, the first track module 5 and the second track module 6 cooperate to guide the push rod 4, allowing it to move relative to the fixed part 1, thereby ensuring that the air guide plate 9 can be stably extended or retracted. In addition, the push rod 4 also has a limiting function, which can prevent the push rod 4 from detaching from the fixed part 1.

[0036] like Figure 1 and Figure 3 As shown, the guide assembly also includes a second drive mechanism 7 and a second transmission mechanism 8. The second drive mechanism 7 is fixedly mounted on the fixing member 1. The second transmission mechanism 8 includes a first pulley 81, a second pulley 82, and a belt 83. The drive end of the second drive mechanism 7 is connected to the first pulley 81, which is rotatably mounted on the fixing member 1. The second pulley 82 is rotatably mounted on the push rod 4 and connected to the air guide plate 9. The first pulley 81 and the second pulley 82 are connected by the belt 83. The second drive mechanism 7 is a motor, and it is fixedly mounted on the first housing 11. The first pulley 81 is rotatably mounted on the first housing 11.

[0037] Specifically, the first drive mechanism 2 drives the first transmission mechanism 3 to rotate forward, causing the push rod 4 to move outward relative to the fixed member 1. Since the first pulley 81 is mounted on the fixed member 1 and the second pulley 82 is mounted on the push rod 4, the distance between the first pulley 81 and the second pulley 82 increases, and the belt 83 gradually tightens as the two sprockets move further apart. When the air guide plate 9 extends outward to its limit relative to the air outlet, the belt 83 is in a taut state. At this time, the second drive mechanism 7 drives the second transmission mechanism 8 to cause the air guide plate 9 to swing relative to the air outlet.

[0038] When the air guide plate 9 needs to retract inward, the second drive mechanism 7 is first controlled to drive the second transmission mechanism 8, so that the air guide plate 9 is reset. Then, the second drive mechanism 7 is stopped, and the first drive mechanism 2 drives the first transmission mechanism 3 to rotate in the opposite direction, so that the push rod 4 moves inward relative to the fixed part 1. This reduces the distance between the first pulley 81 and the second pulley 82, and the belt 83 gradually loosens as the two sprockets get closer together. When the air guide plate 9 retracts inward to its limit position relative to the air outlet, the belt 83 is in a slack state.

[0039] It should be noted that the belt 83 is always connected to the first pulley 81 and the second pulley 82, and will not disengage from the first pulley 81 and the second pulley 82 due to the belt 83 becoming loose. Furthermore, it should be noted that although the second transmission mechanism 8 is described above in conjunction with a "belt + pulley" structure, this is not limiting. Those skilled in the art can also use a "sprocket + chain" structure as needed, and such adjustments are within the scope of protection of this invention.

[0040] The advantage of the above structure is that, in addition to extending outward or retracting inward relative to the air outlet, the air guide plate 9 can also swing up and down relative to the air outlet under the action of the second drive mechanism 7 and the second transmission mechanism 8, so as to meet the user's needs in terms of air delivery range and air delivery mode.

[0041] Furthermore, by setting the second drive mechanism 7 on the fixed part 1 and connecting it to the air guide plate 9 through the second transmission mechanism 8, instead of directly connecting the second drive mechanism 7 to the air guide plate 9, the load-bearing pressure at the end of the push rod 4 is reduced, avoiding "top-heavy" structure, the structural layout is reasonable, and the air guide plate 9 can be stably extended or retracted.

[0042] There are two sets of guide components, which are symmetrically arranged on the left and right sides of the air guide plate 9 to ensure the stable operation of the air guide plate 9.

[0043] The working process of this invention is as follows: Figure 1As shown, when the first drive mechanism 2 rotates forward via the drive gear, it drives the rack 33 to slide outward relative to the fixed member 1, thereby driving the air guide plate 9 to extend outward relative to the air outlet via the push rod 4. At the same time, the belt 83 gradually tightens as the two sprockets move further apart, and when the air guide plate 9 extends outward relative to the air outlet to its limit position, the belt 83 is in a taut state. At this time, the second drive mechanism 7 controls the first pulley 81, belt 83 and second pulley 82 to rotate in both directions, thereby causing the air guide plate 9 to swing up and down relative to the air outlet.

[0044] When the air guide plate 9 needs to retract inward, first control the second drive mechanism 7 to drive the second transmission mechanism 8 so that the air guide plate 9 is reset, and then control the second drive mechanism 7 to stop working.

[0045] like Figure 7 As shown, when the first drive mechanism 2 drives the gear to rotate in the opposite direction, it causes the rack 33 to slide inward relative to the fixed member 1, which in turn causes the guide plate 9 to retract inward relative to the air outlet via the push rod 4. At the same time, the belt 83 gradually loosens as the two sprockets get closer to each other. When the guide plate 9 retracts inward relative to the air outlet to its limit position, the belt 83 is in a slack state.

[0046] Based on the various embodiments described above, the present invention also provides an indoor unit, which includes the guide device described above.

[0047] Example 2

[0048] The difference from Example 1 is that, as Figures 4-6 As shown, the first transmission mechanism 3 includes a cam 34, a first connecting rod 35, a second connecting rod 36, and a cylindrical pin 37. The cam 34 is connected to the driving end of the first driving mechanism 2 and is rotatably mounted on the fixed member 1. One end of the second connecting rod 36 is rotatably connected to the push rod 4, and the other end of the second connecting rod 36 is rotatably connected to one end of the first connecting rod 35. The other end of the first connecting rod 35 is rotatably connected to the cylindrical pin 37, which is in contact with the cam 34. The surface of the cam 34 is a smooth curved surface. The first driving mechanism 2 drives the cam 34 to rotate, causing the cylindrical pin 37 to roll along the surface of the cam 34. Since the cam 34 is a non-circular structure, it sequentially drives the first connecting rod 35, the second connecting rod 36, and the push rod 4 to slide relative to the fixed member 1, thereby causing the air guide plate 9 to extend outward or retract inward relative to the air outlet.

[0049] Specifically, the first drive mechanism 2 drives the cam 34 to rotate in the forward direction, so as to drive the first connecting rod 35, the second connecting rod 36 and the push rod 4 to slide outward relative to the fixed member 1 in sequence, thereby driving the air guide plate 9 to extend outward relative to the air outlet; the first drive mechanism 2 drives the cam 34 to rotate in the reverse direction, so as to drive the first connecting rod 35, the second connecting rod 36 and the push rod 4 to slide inward relative to the fixed member 1 in sequence, thereby driving the air guide plate 9 to retract inward relative to the air outlet.

[0050] It should be noted that although the above description is based on the structure of "first link 35 + second link 36", it is not restrictive. Those skilled in the art can also use only one link or two or more links as needed, and the above adjustments are within the protection scope of this invention.

[0051] Furthermore, the fixing member 1 is also provided with a third guide groove 13 and a limiting groove 14, and the cylindrical pin 37 is provided with a sliding post 38 and a limiting post 39. The sliding post 38 cooperates with the third guide groove 13, and the limiting post 39 cooperates with the limiting groove 14. The third guide groove 13 and the limiting groove 14 are connected to each other. When the air guide plate 9 extends outward relative to the air outlet, the limiting post 39 can slide into the limiting groove 14 and cooperate with the limiting groove 14 to limit the cylindrical pin 37. When the air guide plate 9 retracts inward relative to the air outlet, the limiting post 39 can slide into the third guide groove 13 and cooperate with the third guide groove 13 to move relative to each other within the third guide groove 13.

[0052] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
