Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example, to an indoor air conditioning unit. Background Technology

[0002] To achieve a wider airflow angle adjustment, existing air conditioner air deflectors typically employ the following two solutions:

[0003] The first approach involves leaving a large gap between the air guide plate and the air conditioner to allow the plate to rotate. However, this approach is limited by the air duct, restricts the plate's rotation, and the large gap affects aesthetics and does not prevent dust accumulation, leading to dust buildup inside the air conditioning duct and failing to meet health requirements.

[0004] The second approach uses a robotic arm-type large guide plate. A motion mechanism moves the entire guide plate out of the unit, and then the guide plate rotates along its connecting axis to the robotic arm under the control of the motion mechanism, allowing for large-angle rotation. However, this approach requires at least two sets of motion mechanisms to extend and rotate the guide plate. The increased number of mechanisms raises the cost of the air conditioner, and also increases the probability of malfunction, resulting in lower reliability of the guide plate's movement. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides an indoor air conditioning unit to solve the problem of complex large-angle rotation drive structure for the air guide plate.

[0012] Optionally, a support member is provided in the middle of the air guide plate body, and a second guide part is provided on the support member.

[0013] Optionally, a second guide rail is provided in the middle of the air guide plate bracket. The second guide rail cooperates with the second guide part and is used to guide the support member.

[0014] Optionally, the second guide rail includes a V-shaped rail, which mates with the second guide portion.

[0015] Optionally, the connecting part includes: a connecting plate body, one side of which is connected to the rack part and the other side of which is connected to the first guide part; a plug-in seat, which is disposed between the connecting plate body and the rack part; the air guide plate body is detachably connected to the rack connecting plate through the plug-in seat.

[0016] Optionally, the driving component includes: a gear located between the first rack and the second rack, the gear being used to drive the first rack or the second rack; and a motor being used to drive the gear; when the gear drives the first rack, the air guide plate body rotates about a first rotation center as an axis, so that the air guide plate body is in an upward opening state; when the gear drives the second rack, the air guide plate body rotates about a second rotation center as an axis, so that the air guide plate body is in a downward opening state.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] Combination Figure 1-3 As shown, this embodiment of the present disclosure provides an indoor air conditioning unit, including an air guide plate 30, a rack and pinion connecting plate 20, a drive assembly 10, and an air guide plate bracket 40.

[0045] The air guide plate 30 includes the air guide plate body 31.

[0046] The rack connecting plate 20 is provided with a rack portion 21, a connecting portion 22 and a first guide portion 23. The rack portion 21 is used to enable the air guide plate 30 to open upward and downward. The connecting portion 22 is used to connect with the air guide plate body 31. The first guide portion 23 is used to guide the rotation of the rack connecting plate 20.

[0047] The drive assembly 10 cooperates with the rack part 21 to drive the rack connecting plate 20 to rotate.

[0048] The air guide plate bracket 40 is provided with a first guide rail 41 that cooperates with the first guide part 23. The first guide part 23 and the first guide rail 41 cooperate to guide the air guide plate 30 to open upward and downward.

[0049] The rack connecting plate 20 of this application integrates functional components for opening the air guide plate 30 upward and downward on the rack part 21. The drive assembly 10 can cooperate with the rack part 21 to drive the rack connecting plate 20 to rotate. Therefore, this application can use only one drive mechanism to enable the air guide plate 30 to achieve both upward and downward opening states.

[0050] Furthermore, since the air guide plate 30 is connected to the rack and pinion connecting plate 20, the air guide plate 30 can rotate at a large angle with the cooperation of the drive assembly 10 and the rack and pinion connecting plate 20. At the same time, the air guide plate 30 can be closed without creating obvious gaps that would affect the use of the air conditioner.

[0051] The cooperation between the first guide rail 41 and the first guide part 23 enables the rack connecting plate 20 to be installed on the air guide plate bracket 40, so as to ensure a stable connection between the drive assembly 10 and the rack connecting plate 20.

[0052] Combination Figure 4 As shown, optionally, the rack portion 21 includes a first rack 214 and a second rack 215.

[0053] The first rack 214 extends in an arc shape to one end of the rack connecting plate 20, and the second rack 215 extends in an arc shape to the other end of the rack connecting plate 20.

[0054] This can be understood as follows: the first ends of the first rack 214 and the second rack 215 are both located in the lower middle part of the rack connecting plate 20. The first rack 214 extends in an arc towards one end of the rack connecting plate 20, and the second rack 215 extends in an arc towards the other end of the rack connecting plate 20. The center of the arc of the first rack 214 is located below one side of the rack connecting plate 20, and the center of the arc of the second rack 215 is located below the other side of the rack connecting plate 20. The rack connecting plate 20 can rotate around the centers of the arcs of the first rack 214 and the second rack 215, respectively. Since the centers of the arcs of the first rack 214 and the second rack 215 are both located on the side of the rack connecting plate 20, compared to a structure where the center of rotation is located in the middle, the rack connecting plate 20 and the air guide plate 30 connected to it can rotate at a large angle to achieve large-area air delivery.

[0055] Optionally, the rack portion 21 has an outwardly opening U-shaped structure. The U-shaped structure includes a bottom 213 and a first side portion 211 and a second side portion 212 extending outward along the bottom 213. The first rack 214 is disposed on the first side portion 211, and the second rack 215 is disposed on the second side portion 212, as shown below. Figure 4 As shown.

[0056] This can be understood as follows: both the first rack 214 and the second rack 215 are arc-shaped structures. The teeth of both racks 214 and 215 are set on the convex surface of the arc-shaped structure, and the teeth of both racks 214 and 215 are set towards the gear 11. The first end of the first rack 214 is close to the first end of the second rack 215, and the second end of the first rack 214 is far from the second end of the second rack 215. The initial position of the gear 11 is located at the bottom 213 of the U-shaped structure. When the gear 11 drives the first rack 214, the rack connecting plate 20 rotates around the arc center of the first rack 214, and drives the air guide plate body 31 to rotate, so that the air guide plate 30 is in an upward opening state. When the gear 11 drives the second rack 215, the rack connecting plate 20 rotates around the arc center of the second rack 215, and drives the air guide plate body 31 to rotate, so that the air guide plate 30 is in a downward opening state.

[0057] Combination Figure 7 As shown, optionally, the first guide rail 41 includes: a first rail 411, which has a V-shaped structure, with an open end at the first end and a closed end at the second end; a second rail 412, which has a V-shaped structure, with both the first and second ends being closed ends; and a third rail 413, which has a V-shaped structure, with an open end at the first end and a closed end at the second end; wherein the first rail 411 and the third rail 413 are symmetrically arranged on both sides of the second rail 412.

[0058] As an example, the volumes of the first orbital 411 and the third orbital 413 are smaller than the volume of the second orbital 412.

[0059] Combination Figure 5 As shown, optionally, the first guide portion 23 includes: a first slider 231 located above one side of the rack connecting plate 20, the first slider 231 being slidably engaged with the first track 411; a second slider 232 located above the middle of the rack connecting plate 20, the second slider 232 being slidably engaged with the second track 412; and a third slider 233 located above the other side of the rack connecting plate 20, the third slider 233 being slidably engaged with the third track 413.

[0060] As an example, the rack connecting plate 20 is provided with a first slider 231, a second slider 232, and a third slider 233, which respectively cooperate with the first track 411, the second track 412, and the third track 413 on the guide plate bracket. The first track 411 and the second track 412 are used to guide the rack connecting plate 20 to drive the air guide plate 30 to open downwards. At this time, the third slider 233 of the rack connecting plate 20 disengages from the third track 413; Figure 2 As shown, the second track 412 and the third track 413 cooperate to guide the rack connecting plate 20 to drive the air guide plate 30 to open upwards. At this time, the first slider 231 of the rack connecting plate 20 disengages from the first track 411. The first end of the first track 411 and the first end of the third track 413 are located near the second track 412. Both ends of the second track 412 are closed, which limits the range of motion of the rack connecting plate 20 and prevents it from derailing during rotation.

[0061] Combination Figure 7 As shown, optionally, the rack connecting plate 20 includes a first rack connecting plate and a second rack connecting plate.

[0062] The first rack connecting plate is located at one end of the air guide plate body 31; the second rack connecting plate is located at the other end of the air guide plate body 31.

[0063] It can be understood that the rack connecting plate 20 is set at both ends of the air guide plate body 31, thereby facilitating the installation of the air guide plate body 31 and the driving assembly 10 driving the rack connecting plate 20 and the air guide plate 30.

[0064] Combination Figures 6 to 8 As shown, optionally, a support member 32 is provided in the middle of the air guide plate body 31, and a second guide part 321 is provided on the support member 32. A second guide rail 42 is provided in the middle of the air guide plate bracket 40. The second guide rail 42 cooperates with the second guide part 321 and is used to guide the support member 32. The second guide rail 42 includes a V-shaped rail, which cooperates with the second guide part 321.

[0065] This can be understood as the support member 32 supporting the air guide plate 30 to prevent the air guide plate 30 from bending due to excessive force concentration. Since the support member 32 is located in the middle, and the first rack connecting plate and the second rack connecting plate are located at both ends of the air guide plate body 31, the drive assembly 10 can drive the air guide plate body 31 to rotate from both ends. The support member 32 can support the air guide plate 30 from the middle of the air guide plate body 31, and guide the movement of the support member 32 through the cooperation of the first guide rail 41 and the second guide part 321, so that the air guide plate 30 and the support member 32 can move synchronously.

[0066] Combination Figure 4 , Figure 5 As shown, optionally, the connecting part 22 includes a connecting plate body 221 and a plug-in part.

[0067] One side of the connecting plate body 221 is connected to the rack portion 21, and the other side is connected to the first guide portion 23; the plug-in seat 222 is disposed between the connecting plate body 221 and the rack portion 21; the air guide plate body 31 is detachably connected to the rack connecting plate 20 through the plug-in seat 222.

[0068] It can be understood that the rack connecting plate 20 and the air guide plate body 31 are detachably connected, and the plug-in seat 222 is located between the connecting plate body 221 and the rack part 21.

[0069] As an example, such as Figure 5 , Figure 7 As shown, a locking block 223 is provided inside the plug-in socket 222, and a slot 33 is provided on the air guide plate body 31. The locking block 223 can be engaged with the slot 33.

[0070] Combination Figures 1 to 3 As shown, optionally, the drive assembly 10 includes a gear 11 and a motor 12.

[0071] Gear 11 is located between the first rack 214 and the second rack 215. Gear 11 is used to drive the first rack 214 or the second rack 215. Motor 12 is used to drive gear 11. When gear 11 drives the first rack 214, the air guide plate body 31 rotates about the first rotation center as the axis, so that the air guide plate body 31 is in an upward opening state. When gear 11 drives the second rack 215, the air guide plate body 31 rotates about the second rotation center as the axis, so that the air guide plate body 31 is in a downward opening state.

[0072] This can be understood as follows: Gear 11 is located between the first rack 214 and the second rack 215, and is used to drive either the first rack 214 or the second rack 215; Motor 12 is used to drive Gear 11. When Gear 11 drives the first rack 214, the air guide plate 30 rotates about the arc center of the first rack 214, i.e., the first rotation center, so that the air guide plate body 31 is in an upward opening state; when Gear 11 drives the second rack 215, the air guide plate body 31 rotates about the arc center of the second rack 215, i.e., the second rotation center, so that the air guide plate body 31 is in a downward opening state. The first rotation center is the virtual rotation axis of the first rack 214, and the second rotation center is the virtual rotation axis of the second rack 215. Optionally, the first rotation center and the second rotation center do not overlap.

[0073] Gear 11 can mesh with either the first rack 214 or the second rack 215, driving either rack 214 or rack 215 to rotate. When gear 11 drives the first rack 214 to rotate, gear 11 and rack 215 are not meshed; when gear 11 drives rack 215 to rotate, gear 11 and rack 214 are not meshed. The first rack 214 is mainly used to keep the air guide plate 30 in an upward opening state, and the second rack 215 is mainly used to keep the air guide plate 30 in a downward opening state. The rack connecting plate 20 mainly plays a transmission role. Since the first rack 214 and the second rack 215 are mounted on the rack connecting plate 20 and the rack connecting plate 20 is connected to the air guide plate 30, when the first rack 214 or the second rack 215 moves under the drive of gear 11, the air guide plate 30 will also move accordingly.

[0074] As an example, both the first rack 214 and the second rack 215 have an arc-shaped structure. The first end of the first rack 214 is close to the first end of the second rack 215, and the second end of the first rack 214 is far from the second end of the second rack 215. The gear 11 is initially located at the first ends of both the first rack 214 and the second rack 215, and meshes with both racks simultaneously. Figure 1 As shown. At this time, the air guide plate 30 is in the closed state. When the gear 11 needs to drive the first rack 214 or the second rack 215, the gear 11 is rotated in the corresponding driving direction and disengaged from the other rack. When the air guide plate 30 needs to be closed or opened in another direction, the gear 11 is rotated in the opposite direction to the initial driving direction.

[0075] The following is combined with Figures 1 to 3 The motion principle of the embodiments of this disclosure will be explained.

[0076] The teeth of the first rack 214 and the second rack 215 are both disposed on the convex surface of the arc-shaped structure. The first ends of the first rack 214 and the second rack 215 are both located in the lower middle part of the rack connecting plate 20. The first rack 214 extends arc-shaped towards one end of the rack connecting plate 20, and the second rack 215 extends arc-shaped towards the other end of the rack connecting plate 20. That is, the first end of the first rack 214 is close to the first end of the second rack 215, and the second end of the first rack 214 is far from the second end of the second rack 215. The arc center of the first rack 214 is located below one side of the rack connecting plate 20, and the arc center of the second rack 215 is located below the other side of the rack connecting plate 20. The rack connecting plate 20 can rotate about the arc centers of the first rack 214 and the second rack 215 respectively. The gear 11 is initially located at the first ends of the first rack 214 and the second rack 215.

[0077] In implementation, gear 11 initially meshes with both the first rack 214 and the second rack 215. When the air guide plate 30 needs to be in an upward opening state, gear 11 rotates in the first direction from its initial state. During this process, gear 11 disengages from the second rack 215 and begins to drive the first rack 214. At this time, the first rack 214 rotates around the first rotation center, causing the air guide plate 30 to open upward. By controlling the rotation angle of gear 11 or the displacement of gear 11 on the first rack 214, the size of the upward opening of the air guide plate 30 can be adjusted. When it is necessary to close the air guide plate 30, gear 11 rotates in the second direction, driving the rack connecting plate 20 back to its initial position via the first rack 214. Wheel 11 engages with the first ends of the first rack 214 and the second rack 215 simultaneously. When it is necessary to switch the air guide plate 30 from the upward opening state to the downward opening state, firstly, the gear 11 is rotated in the second direction to return the rack connecting plate 20 to the initial position. Then, it continues to rotate in the second direction to disengage the gear 11 from the first rack 214 and start driving the second rack 215. The second rack 215 rotates around the second rotation center as an axis, driving the air guide plate 30 to open downward. By controlling the rotation angle of the gear 11 or the displacement of the gear 11 on the second rack 215, the size of the downward opening of the air guide plate 30 can be adjusted.

[0078] Similarly, when the air guide plate 30 needs to be in a downward opening state, the gear 11 starts from the initial state and rotates in the second direction. During this process, the gear 11 disengages from the first rack 214 and begins to drive the second rack 215. At this time, the second rack 215 rotates around the second rotation center, causing the air guide plate 30 to open downward. By controlling the rotation angle of the gear 11 or the displacement of the gear 11 on the second rack 215, the size of the downward opening of the air guide plate 30 can be adjusted. When it is necessary to close the air guide plate 30, the gear 11 rotates in the first direction, and the second rack 215 drives the rack connecting plate 20 back to the initial position. When gear 11 meshes with the first ends of the first rack 214 and the second rack 215 again, when it is necessary to switch the air guide plate 30 from the downward opening state to the upward opening state, firstly, gear 11 is rotated in the first direction to return the rack connecting plate 20 to the initial position, and then it continues to rotate in the first direction to disengage gear 11 from the second rack 215 and start driving the first rack 214. The first rack 214 rotates around the first rotation center as the axis, driving the air guide plate 30 to open upward. By controlling the rotation angle of gear 11 or the displacement of gear 11 on the first rack 214, the size of the upward opening of the air guide plate 30 can be adjusted.

[0079] Optionally, when gear 11 is located on the perpendicular bisector of the line connecting the arc centers of the first rack 214 and the second rack 215, the air guide plate 30 is in a closed state, such as... Figure 1 As shown.

[0080] This can be understood as follows: since the position of gear 11 remains unchanged, when gear 11 drives the first rack 214 or the second rack 215 to rotate, the rack connecting plate 20 will also move accordingly. The line connecting the arc centers of the first rack 214 and the second rack 215 and its perpendicular bisector will also be in motion with the movement of the rack connecting plate 20. Only when the rack connecting plate 20 returns to its initial position, that is, when gear 11 meshes with both the first rack 214 and the second rack 215 simultaneously, is the air guide plate 30 in the closed state. When gear 11 meshes with only one rack, it will be in the open state. Figures 1 to 3 As shown.

[0081] Combination Figures 9 to 11 As shown, the indoor unit of the air conditioner may optionally include a gearbox 13.

[0082] The gear box 13 is provided with a motor receiving cavity 131 and a connecting plate mounting area 132. The gear box 13 has an open structure, including a mounting opening 133 and a rotating opening 134. The mounting opening 133 is used for the rack connecting plate 20 to cooperate with the air guide plate bracket 40, and the rotating opening 134 is used for the rack connecting plate 20 to drive the air guide plate 30 to rotate.

[0083] This can be understood as follows: during installation, the mounting opening 133 of the gear box 13 faces the air guide plate bracket 40. The gear box 13 is fixed to the air guide plate bracket 40 by a connector. The motor 12 is installed in the motor receiving cavity 131. The motor 12 is connected to the gear 11. The gear 11 meshes with the first rack 214 or the second rack 215 on the rack connecting plate 20. The rack connecting plate 20 is rotatably installed in the connecting plate mounting area 132. The rack connecting plate 20 is installed on the air guide plate bracket 40 through the first guide part 23 to ensure a stable connection between the gear 11 and the rack connecting plate 20.

[0084] This application provides an indoor air conditioning unit that can be driven by a set of drive devices to rotate the air guide plate 30 at a large angle.

[0085] This application integrates a first rack 214 for opening the air guide plate 30 upwards and a second rack 215 for opening the air guide plate 30 downwards onto a rack connecting plate 20. A gear 11 can drive either the first rack 214 or the second rack 215. When the gear 11 drives the first rack 214, the air guide plate 30 is in an upward-opening state; when the gear 11 drives the second rack 215, the air guide plate 30 is in a downward-opening state. Therefore, this application can achieve both upward and downward opening states for the air guide plate 30 using only one drive mechanism, while also enabling the air guide plate 30 to close. The air conditioner indoor unit provided by this disclosure has fewer moving mechanisms for driving the air guide plate 30, reducing the probability of air guide plate 30 movement failure and improving the reliability of the air guide plate 30 movement.

[0086] Furthermore, since the air guide plate 30 is connected to the rack and pinion connecting plate 20, the air guide plate 30 can achieve a large-angle rotation through the cooperation of the gear 11 and the rack and pinion connecting plate 20 without producing obvious gaps that would affect the use of the air conditioner.
