Description

Technical Field

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

[0002] With the development of science and technology, the number of air conditioners is constantly increasing, and their functions are becoming more and more diverse. In particular, as people's living standards continue to improve, users have a great demand for the diversified functions of air conditioners. For example, the wide-range airflow function of air conditioners, and the left and right swing airflow for rapid cooling or heating modes, all require the air conditioner's oscillating blades to work together to achieve these functions.

[0003] Currently, in existing technologies, whether it is a wall-mounted air conditioner indoor unit or a floor-standing air conditioner indoor unit, the swivel blades of the air conditioner are all arranged at the same angle to cooperate with the air guide plate to achieve different air delivery modes. This limits the diversified development of air delivery modes, resulting in a single air delivery mode for the air conditioner. In addition, existing air conditioners also have problems such as unnatural airflow and a strong feeling of direct airflow, all of which reduce the user experience. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide an air conditioner indoor unit that overcomes or at least partially solves the above problems.

[0039] In the indoor unit of this air conditioner, when the unit is running, the drive device can drive at least one swing blade to swing in a direction different from the other swing blades. Multiple swing blades can deliver air at different angles, enriching the air delivery modes of the indoor unit. Furthermore, because the airflow from the outlet is turbulent, it is more like a natural breeze, preventing the user from feeling a direct draft. Therefore, this invention enhances the diversity of air delivery modes, making the airflow from the indoor unit more natural and reducing the direct draft, thus improving the user experience.

[0040] Furthermore, the drive unit causes the movable part, made of flexible material, to oscillate flexibly relative to the fixed part. Due to the flexibility of the movable part, its oscillation process can be arc-shaped, reducing wind resistance and making the airflow smoother and more gentle. This effectively reduces the airflow cutting noise and mechanical noise generated by traditional rigid blades, improving the quietness of operation, and also creates a gentler, wider-coverage airflow. It further avoids the discomfort of direct airflow, comprehensively improving the quietness and comfort of air conditioning operation, and further enhancing the user experience.

[0058] Figure 1 This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 11 This utility model provides an indoor unit for an air conditioner, including a housing 100, multiple swing blades 300, and a driving device. A support frame 120 is disposed within the housing 100, and an air outlet 110 is provided on the housing 100. Multiple swing blades 300 are disposed within the housing 100 and adjacent to the air outlet 110; the multiple swing blades 300 are sequentially and spaced apart along the length of the air outlet on the support frame 120; each swing blade 300 includes a fixed portion 301 and a movable portion 302, the fixed portion 301 and the movable portion 302 are connected, the fixed portion 301 is located on the air inlet side of the movable portion 302, the fixed portion 301 is fixedly disposed to the support frame 120, and the movable portion 302 is made of a flexible material. The driving device is configured to drive the movable portion 302 to swing relative to the fixed portion 301, and is configured such that the swing direction of at least one movable portion 302 is different from the swing direction of the other movable portions 302. Specifically, among the multiple moving parts, the swing direction of at least one moving part can be opposite to the swing direction of the other moving parts, so as to form at least one air gathering channel and one air dissipation channel.

[0059] In this embodiment, when the indoor unit of the air conditioner is running, the driving device can drive the swing direction of the movable part 302 of at least one swing blade 300 to be different from the swing direction of the movable parts 302 of the other swing blades 300. Multiple swing blades 300 can deliver air at different air delivery angles, thus enriching the air delivery modes of the indoor unit. Furthermore, when multiple swing blades 300 can deliver air at different air delivery angles, the direction of the airflow from the outlet is turbulent, making the airflow more like a natural breeze, thus preventing the user from feeling a direct airflow. Therefore, this invention can improve the diversity of air delivery modes, making the airflow from the indoor unit of the air conditioner more natural, reducing the feeling of a direct airflow, and improving the user experience.

[0060] Furthermore, the drive unit causes the movable part 302, made of flexible material, to oscillate flexibly relative to the fixed part 301. Due to the flexibility of the movable part 302, its oscillation process can be arc-shaped, reducing wind resistance and making the airflow smoother and more gentle. This effectively reduces the airflow cutting noise and mechanical noise generated when the traditional rigid blades 300 oscillate, improving the quietness effect, and also creates a gentler airflow with a wider coverage area. It further avoids the discomfort of direct airflow, comprehensively improving the quietness and airflow comfort of the air conditioner, and further enhancing the user experience.

[0061] In some alternative embodiments of the present invention, the drive device is configured such that the swing direction of one movable part 302 is different from the swing direction of the other movable parts 302.

[0062] In some alternative embodiments of the present invention, the drive device is configured such that the swing direction of the two movable parts 302 is different from the swing direction of the other movable parts 302.

[0063] In some alternative embodiments of the present invention, the drive device is configured such that the swing direction of two or more movable parts 302 is different from the swing direction of the remaining movable parts 302.

[0064] In some optional embodiments of this utility model, such as Figure 2 As shown, the drive device is configured such that the swing directions of every two adjacent movable parts 302 are opposite. In this embodiment, because the adjacent movable parts 302 swing in opposite directions, the airflow can achieve more complete and uniform diffusion and mixing, significantly improving the width and uniformity of the air outlet coverage and effectively reducing dead zones in the air supply.

[0065] In some optional embodiments of this utility model, the air inlet end of the fixing part 301 is fixedly disposed with the support frame 120.

[0066] In some optional embodiments of this utility model, the air outlet end of the fixing part 301 is fixedly disposed with the support frame 120.

[0067] In some optional embodiments of this utility model, both sides of the fixing part 301 are fixedly disposed with the support frame 120. That is, both the air inlet end and the air outlet end of the fixing part 301 are fixedly disposed with the support frame 120. Compared with the previous two embodiments with single-sided fixing, this embodiment improves the connection between the fixing part 301 and the support frame 120 by fixing the fixing part 301 with both sides.

[0068] In some optional embodiments of this utility model, the movable part 302 is rotatably connected to the support frame 120 via a rotating shaft 310.

[0069] In this embodiment, the movable part 302 is rotatably connected to the support frame 120 via a rotating shaft 310. The driving device directly drives the rotating shaft 310 to cause the flexible movable part 302 to swing around a fixed fulcrum. The rotating shaft 310 provides a stable rotation fulcrum, ensuring the high-speed response and swing angle control accuracy of the movable part 302; and it is also easy to manufacture and assemble.

[0070] In some optional embodiments of this utility model, the driving device includes a first driving unit and a second driving unit. The first driving unit is configured to drive a portion of the movable parts 302 to rotate. The second driving unit is configured to drive the remaining movable parts 302 to rotate. The first driving unit and the second driving unit are controlled independently or in conjunction, so that the swing direction of all the movable parts 302 is the same, or that the swing direction of at least one movable part 302 is different from the swing direction of the remaining movable parts 302. The first driving unit includes a first connecting rod 710 extending along the length direction of the air outlet, and the corresponding movable part 302 is rotatably mounted on the first connecting rod 710. The second driving unit includes a second connecting rod 720 extending along the length direction of the air outlet, and the corresponding movable part 302 is rotatably mounted on the second connecting rod 720.

[0071] In this embodiment, the first drive unit and the second drive unit enable global and flexible control of multiple oscillating blades 300. This drive device has the advantages of being easy to manufacture, assemble, and maintain.

[0072] In some optional embodiments of this utility model, the first link 710 and the second link 720 are each driven by a motor. The first driving part and the second driving part are controlled independently or in conjunction.

[0073] The first drive unit also includes a first motor and a first remote control. One end of the first remote control is rotatably connected to the end of the first connecting rod 710, and the other end of the first remote control is rotatably connected to the output shaft of the first motor. The second drive unit also includes a second motor and a second remote control. One end of the second remote control is rotatably connected to the end of the second connecting rod 720, and the other end of the second remote control is rotatably connected to the output shaft of the second motor. The first motor drives the first rocker arm to perform circular motion, converting the rotation into the reciprocating oscillation of the first connecting rod 710 through the hinge point at the end of the first rocker arm, thereby causing the movable part 302 on the first connecting rod 710 to deflect synchronously. At the same time, the second motor independently drives the second rocker arm to move, causing the movable part 302 on the second connecting rod 720 to deflect independently. When the first motor and the second motor rotate in the same direction and at the same speed, all movable parts 302 oscillate in the same direction to achieve concentrated air supply; when the first motor and the second motor rotate in opposite directions, the movable parts 302 on the first connecting rod 710 and the second connecting rod 720 oscillate in opposite directions to form turbulence.

[0074] In some optional embodiments of this utility model, such as Figure 4 and Figure 5 As shown ( Figure 5 yes Figure 4 (Side view), the first drive unit and the second drive unit are linked for control, that is, the first link 710 and the second link 720 are driven by the same motor.

[0075] The drive unit also includes a drive motor 730, a rotating disk 740, a first remote lever 750, and a second remote lever 760. The output shaft of the drive motor 730 is coaxially arranged with the rotating disk 740. A first connecting rod 710 is connected to a first position of the rotating disk 740 via the first remote lever 750, and a second connecting rod 720 is connected to a second position of the rotating disk 740 via the second remote lever 760. Both the first and second positions are spaced apart from the central axis of the rotating disk, with the first position located on one side of the rotating disk 740 and the second position located on the other side. The first and second positions are symmetrically distributed at both ends of the radial direction of the rotating disk 740.

[0076] When the drive motor 730 rotates, the first telescopic lever 750 and the second telescopic lever 760 rotate in different directions, thereby enabling the first connecting rod 710 and the second connecting rod 720 to move in different directions. This embodiment significantly reduces energy consumption and manufacturing costs, and reduces assembly space, while ensuring the reverse movement function of the first connecting rod 710 and the second connecting rod 720.

[0077] In some optional embodiments of this utility model, such as Figures 6 to 11 As shown, the driving device includes multiple transmission rotating cylinder shafts 400, a pull rod shaft 510, and a limiting device.

[0078] Multiple transmission rotating cylinder shafts 400 are correspondingly arranged with multiple movable parts 302, and are drivenly connected to the corresponding movable parts 302. The transmission rotating cylinder shafts 400 are arranged along the length direction and are used to drive the corresponding movable parts 302 to swing around their rotation axis 310 in the length direction. The inner wall of the transmission rotating cylinder shaft 400 is provided with a transmission groove 410 that extends spirally along its axial direction, and the pitch of the transmission groove 410 of at least one of the multiple transmission rotating cylinder shafts 400 is different from that of the others. A pull rod shaft 510 extends along its length and passes through multiple transmission rotating cylinder shafts 400. A transmission slider 520 is positioned on its outer periphery corresponding to the position of each transmission rotating cylinder shaft 400. The transmission slider 520 is slidably disposed within a corresponding transmission groove 410. The pull rod shaft 510, when moving relative to the transmission rotating cylinder shafts 400 in the length direction, drives at least one transmission rotating cylinder shaft 400 to rotate relative to the others via the transmission slider 520 and the transmission groove 410. Furthermore, it drives the transmission rotating cylinder shafts 400 to rotate synchronously via the transmission slider 520 during rotation. A limiting device is configured to prevent the transmission rotating cylinder shafts 400 from moving in the length direction.

[0079] It is understood that the transmission rotating cylinder shaft 400 is a hollow structure, that is, a central hole extending axially is provided inside the transmission rotating cylinder shaft 400, and a transmission groove 410 extending spirally axially can be provided on the inner wall of the transmission rotating cylinder shaft 400. Furthermore, the pull rod shaft 510 with a transmission slider 520 on its outer periphery can be inserted into the transmission rotating cylinder shaft 400. When the pull rod shaft 510 is pulled relative to the transmission rotating cylinder shaft 400 in the length direction of the air outlet 110 (or in the axial direction of the pull rod shaft 510 and the transmission rotating cylinder shaft 400), the axial displacement of the cylinder shaft is restricted by the limiting device, and the transmission rotating cylinder shaft 400 can rotate under the action of the transmission slider 520 and the spiral transmission groove 410.

[0080] Furthermore, among the multiple transmission rotating cylinder shafts 400, the pitch of the transmission groove 410 on the inner wall of at least one transmission rotating cylinder shaft 400 is set to be different from the pitch of the transmission groove 410 of the other transmission rotating cylinder shafts 400 (including the pitch of the transmission groove 410 of each transmission rotating cylinder shaft 400 being different). Thus, when the pull rod shaft 510 moves in the length direction relative to all the transmission rotating cylinder shafts 400, it can cause at least one of the multiple transmission rotating cylinder shafts 400 to rotate asynchronously with the other transmission rotating cylinder shafts 400, so that at least one of the multiple swing blades 300 will rotate to a position with an angle different from the other swing blades 300.

[0081] When the pull rod shaft 510 rotates, the transmission slider 520 on the pull rod shaft 510 can drive its corresponding transmission rotating cylinder shaft 400 to rotate, and thus multiple transmission rotating cylinder shafts 400 can rotate synchronously.

[0082] Furthermore, when the pull rod shaft 510 is configured to move back to its initial position along its length, all the oscillating blades 300 will be reset to the same swing angle or air delivery angle. Then, the transmission rotating cylinder shaft 400 is configured to rotate synchronously, and each oscillating blade 300 will swing in the same direction, causing the outlet airflow to be directed or swept.

[0083] In summary, this embodiment can enable at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and drive all transmission rotating cylinder shafts 400 to rotate synchronously, thereby increasing the diversity of air supply modes of the air conditioner indoor unit, making the airflow of the air conditioner more natural, reducing the direct blowing sensation of the airflow, and improving the user experience.

[0084] In some optional embodiments of this utility model, such as Figure 9 and Figure 10As shown, the limiting device includes a transmission limiting mounting part 530 and a rotation drive member 600. One end of the plurality of transmission rotating cylinder shafts 400 is limited by the transmission limiting mounting part 530, and the other end is limited by the rotation drive member 600.

[0085] The transmission limiting mounting part 530 is located on the leeward side and is connected to the support frame 120. The transmission limiting mounting part 530 has a mounting slot 531 extending along its length, and the pull rod shaft 510 is rotatably connected within the mounting slot 531. It is understood that the transmission limiting mounting part 530 can mount the pull rod shaft 510 onto the support frame 120, thereby mounting the pull rod shaft 510 and multiple transmission rotating cylinder shafts 400 together on the support frame 120. The transmission limiting mounting part 530 abuts against the end of the transmission rotating cylinder shaft 400 furthest from the rotation drive member 600. This embodiment avoids the situation where, when the pull rod shaft 510 rotates, the transmission slider 520 causes the transmission rotating cylinder shaft 400 to move along its length through the transmission groove 410.

[0086] In some optional embodiments of this utility model, such as Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the drive device also includes a pull-out drive 560 and a rotation drive 600. The pull-out drive 560 is drivably connected to one end of the pull rod shaft 510, configured to drive the pull rod shaft 510 to move along its length, and arranged such that the pull rod shaft 510 is allowed to rotate relative to the pull-out drive 560. The rotation drive 600 is drivably connected to the other end of the pull rod shaft 510 or drivably connected to a transmission rotating cylinder shaft 400 located at the other end of the pull rod shaft 510, so as to drive the pull rod shaft 510 and the transmission rotating cylinder shaft 400 on the pull rod shaft 510 to rotate. Specifically, when the pull rod shaft 510 moves, the rotation drive 600 and the adjacent transmission rotating cylinder shaft 400 are allowed to rotate relative to each other.

[0087] In some optional embodiments of this utility model, such as Figure 10 As shown, the driving device further includes a pull-out bracket 540 and two pull-out limiting blocks 550. The pull-out bracket 540 has a pull-out hole extending along its length. One end of the pull rod shaft 510 is rotatably connected to the pull-out hole, and the pull-out bracket 540 allows the pull rod shaft 510 to rotate relative to the pull-out bracket 540 through the pull-out hole. The two pull-out limiting blocks 550 are connected to the pull rod shaft 510 and are located on both sides of the pull-out bracket 540 in the length direction. It can be understood that through the arrangement of the pull-out bracket 540 and the pull-out limiting blocks 550, the pull rod shaft 510 can rotate and move in the length direction under the drive of the pull-out driving member 560.

[0088] In one embodiment of the pull-out drive component 560 in this example, the pull-out drive component 560 can be a cylinder, hydraulic cylinder, or the like. The cylinder body is arranged along the length direction or the axial direction of the pull rod shaft 510, and the piston rod of the cylinder body is connected to the pull-out bracket 540. Thus, the extension and retraction of the cylinder body can drive the pull rod shaft 510 to move along the length direction. Therefore, the pull-out drive component 560 can drive the pull rod shaft 510 to move along the length direction through the contact between the pull-out bracket 540 and the pull-out limiting block 550.

[0089] Reference Figure 10 In another embodiment of the pull-out drive component 560 in this example, the pull-out drive component 560 includes a pull-out drive motor 561 and a pull-out transmission link 562.

[0090] The pull rod motor shaft 5611 of the pull-out drive motor 561 is perpendicular to the pull rod shaft 510. One end of the pull-out transmission link 562 is connected to the pull rod motor shaft 5611, and the pull-out transmission link 562 is arranged radially along the pull rod motor shaft 5611. The other end of the pull-out transmission link 562 is provided with a pull-out sliding hole 5621 extending toward the pull rod motor shaft 5611. The pull-out bracket 540 is provided with a pull-out protrusion 541 extending in the direction of the pull rod motor shaft 5611. The pull-out protrusion 541 is slidably disposed in the pull-out sliding hole 5621.

[0091] Understandably, the pull-out transmission linkage 562 can convert the reciprocating rotation of the pull rod motor shaft 5611 of the pull-out drive motor 561 into the reciprocating movement of the pull-out frame 540 (and the pull rod shaft 510) in the length direction, so that the pull-out drive member 560 can drive the pull rod shaft 510 to move in the length direction through the abutment of the pull-out frame 540 and the pull-out limit block 550.

[0095] In some optional embodiments of this utility model, a connecting drive member is provided between the transmission rotating cylinder shaft 400 and the movable part 302 for transmitting the rotation of the transmission rotating cylinder shaft 400 and converting it into the swing of the corresponding movable part 302 about its rotation axis 310 in the length direction; a drive slide rail 420 extending spirally along its axial direction is provided on the outer wall of the transmission rotating cylinder shaft 400.

[0097] In some optional embodiments of this utility model, in each oscillating blade 300, the ratio between the length of the fixed part 301 along the airflow direction and the length of the movable part 302 along the airflow direction is 0.8 to 1.2.

[0098] In some optional embodiments of this utility model, the fixing part 301 is made of a flexible material, and the material of the fixing part 301 is the same as that of the moving part 302. This arrangement facilitates the manufacturing and assembly of the oscillating blade 300.

[0099] In some optional embodiments of this utility model, the fixed part 301 and the movable part 302 are made of different materials.

[0100] In some optional embodiments of this utility model, such as Figure 1 As shown, the support frame 120 defines an air outlet duct 210, which connects to the air outlet 110; multiple oscillating blades 300 are disposed within the air outlet duct 210 and are adjacent to the air outlet 110.

[0101] In some optional embodiments of this utility model, the indoor unit of the air conditioner can be a wall-mounted air conditioner indoor unit, and the length direction of the air outlet 110 is either left-right or horizontal.

[0102] In some optional embodiments of this utility model, the indoor unit of the air conditioner can also be a vertical air conditioner indoor unit, in which case the length direction of the air outlet 110 is either up and down or vertical.

[0103] Furthermore, the indoor unit of the vertical air conditioner has two air outlets.
