Technical Field

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

[0002] Currently, most indoor units push the guide plate out of the air outlet when supplying air into the room. In order to prevent the heat exchange air from blowing onto the guide plate and reducing the amount of heat exchange air, the guide plate needs to be rotated at a certain angle along one edge so that the guide plate opens the air outlet to supply air into the room.

[0003] In some air conditioner indoor units, a drive mechanism is installed at the guide plate to drive the guide plate out of the air outlet and rotate it. However, the existing drive mechanism has a complex structure, high manufacturing cost, and poor operation stability, which can easily lead to jamming during operation. Utility Model Content

This driving mechanism, through the cooperation of the slide rails and push rods, and the direct meshing transmission of the gear and rack, enables flexible adjustment of the guide plate angle. Firstly, the rotatable connection between the first and second push rods and the guide plate allows the guide plate to be flexibly adjusted as needed, thereby achieving precise control of the airflow direction. This connection method not only improves the flexibility of the mechanism but also further simplifies the structure and reduces manufacturing costs. Secondly, the mechanism cleverly utilizes the cooperation of the slide rails and push rods. Through the first slide rail on the housing and the second slide rail on the first push rod, precise guidance and sliding of the push rod are achieved. This design not only simplifies the structure of the mechanism and reduces the number of parts but also improves the reliability and durability of the mechanism. Simultaneously, the sliding cooperation of the first slider within the two slide rails ensures the stability and accuracy of the push rod during sliding, providing a strong guarantee for the smooth adjustment of the guide plate. Furthermore, the gear and rack meshing transmission method offers advantages such as high transmission efficiency, large torque transmission, and smooth operation. Through the meshing of the gear and rack, the first push rod can be precisely driven to slide in a specified direction, thereby achieving precise adjustment of the guide plate angle. Finally, when the first push rod slides in a certain direction, the first and second slide rails press against the first slider, causing the second push rod to slide in the opposite direction relative to the first push rod. This design not only achieves smooth adjustment of the guide plate but also reduces friction and vibration during movement, further improving the operational stability of the mechanism. In summary, the combined effect of these factors results in the guide plate drive mechanism of this air conditioner indoor unit having the advantages of simple structure, low manufacturing cost, and high operational stability, and the drive mechanism is less prone to jamming during operation.

[0046] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 9 This utility model embodiment provides an air conditioner indoor unit 100, including a housing 10, a guide plate 30, and a drive mechanism 50. The drive mechanism 50 includes a first push rod 522, a second push rod 523, a rack 521, and a gear 525.

[0047] The housing 10 is provided with a first slide rail 535. The guide plate 30 is used to guide the airflow out of the air outlet. One end of the first push rod 522 is rotatably connected to the guide plate 30, and the first push rod 522 is slidably mounted on the housing 10. A second slide rail 524 is provided on the first push rod 522. One end of the second push rod 523 is rotatably connected to the guide plate 30, and the other end of the second push rod 523 is provided with a first slider 5231, which is installed in the second slide rail 524 and the first slide rail 535.

[0048] A rack 521 is mounted on a first push rod 522; a gear 525 meshes with the rack 521 and is used to drive the first push rod 522 to slide along a first direction or a second direction; the first direction is opposite to the second direction.

[0049] When the first push rod 522 slides in the first direction, the first slide rail 535 and the second slide rail 524 press against the first slider 5231, causing the second push rod 523 to slide relative to the first push rod 522 in at least the second direction; when the first push rod 522 slides in the second direction, the first slide rail 535 and the second slide rail 524 press against the first slider 5231, causing the second push rod 523 to slide relative to the first push rod 522 in at least the first direction.

[0050] In this embodiment, the drive mechanism 50 adjusts the position of the guide plate 30 through a series of precise mechanical linkages. At the start of operation, the gear 525 rotates under external power, and the rack 521 meshing with it drives the first push rod 522 to slide along a preset track on the housing 10. The sliding direction of the first push rod 522 is determined by the rotation direction of the gear 525, and can be either a first direction or a second direction opposite to it. As the first push rod 522 slides, the second slide rail 524 on it, together with the first slide rail 535 on the housing 10, acts on the first slider 5231 at the end of the second push rod 523. When the first push rod 522 slides in the first direction, the squeezing action of the slide rail pushes the first slider 5231, allowing the second push rod 523 to move relative to the first push rod 522 at least in the second direction. Due to the combined action of the first and second push rods, the angle of the guide plate changes, thereby altering the direction of the airflow from the outlet. Conversely, when the first push rod 522 slides in the second direction, the first slider 5231 is compressed again. However, at this time, the second push rod 523 can move at least in the first direction relative to the first push rod 522, and the second push rod 523 can also rotate, causing the angle of the guide plate 30 to change. In this way, the drive mechanism 50 can smoothly and precisely control the angle of the guide plate 30 to meet different airflow guidance requirements.

[0051] In this embodiment, the guide plate driving mechanism 50 includes a first push rod, a second push rod, a gear, and a rack. The driving mechanism 50 drives the first push rod to slide through the meshing of the gear and rack. Simultaneously, the cooperation of the first and second slide rails causes the first slider to drive the second push rod to slide in the opposite direction relative to the first push rod, thereby adjusting the position of the guide plate rotatably connected to both and guiding the air conditioning airflow. First, the rotatable connection design between the first and second push rods and the guide plate allows the guide plate to flexibly adjust its angle as needed, thus achieving precise control of the airflow direction. This connection method not only improves the flexibility of the mechanism but also further simplifies the structure and reduces manufacturing costs. Second, the mechanism cleverly utilizes the cooperation of the slide rails and push rods. Through the first slide rail on the housing and the second slide rail on the first push rod, precise guidance and sliding of the push rod are achieved. This design not only simplifies the structure of the mechanism and reduces the number of parts but also improves the reliability and durability of the mechanism. At the same time, the sliding cooperation of the first slider within the two slide rails ensures the stability and accuracy of the push rod during the sliding process, providing a strong guarantee for the smooth adjustment of the guide plate. Furthermore, the gear and rack transmission method offers advantages such as high transmission efficiency, large torque transmission, and smooth movement. Through the meshing of the gear and rack, the first push rod can be precisely driven to slide in a specified direction, thereby achieving precise adjustment of the guide plate angle. Finally, when the first push rod slides in a certain direction, the first and second slide rails press against the first slider, causing the second push rod to slide in the opposite direction relative to the first push rod. This design not only achieves smooth adjustment of the guide plate but also reduces friction and vibration during movement, further improving the operational stability of the mechanism.

[0052] In summary, the combined effect of the above factors results in the air conditioner indoor unit's guide plate drive mechanism 50 having the advantages of simple structure, low manufacturing cost, and high operational stability, and the drive mechanism 50 is not prone to jamming during operation.

[0053] Furthermore, the first direction is the front side, and the second direction is the rear side. The air outlet is located on the front side of the indoor unit 100 of the air conditioner. The first push rod 522 is connected to the lower end of the guide plate 30, and the second push rod 523 is connected to the upper end of the guide plate 30. The first push rod 522 pushes the guide plate 30 forward. The first slider slides backward along the second slide rail 524. That is, when the second push rod 523 moves forward at the lower end of the guide plate 30, it pulls the upper end of the guide plate 30 backward, causing the guide plate 30 to rotate.

[0054] In some other embodiments of this utility model, a first push rod 522 and a second push rod 523 form a group. The first push rod 522 and the second push rod 523 can be a group or multiple groups. When multiple groups are set, the multiple groups are respectively connected to different parts of the guide plate 30, and move synchronously to drive the guide plate 30 to extend, retract, and translate. This makes the movement of the guide plate 30 more stable, especially for the long strip-shaped guide plate 30.

[0055] Furthermore, in some embodiments of this utility model, such as Figure 2 As shown, the guide plate 30 is a long strip extending laterally. The first push rod 522 and the second push rod 523 are two sets, which are respectively connected to the two ends of the guide plate 30 in the lateral direction, that is, the two ends of the guide plate 30 in the length direction.

[0056] In some embodiments of this utility model, such as Figures 3 to 6 As shown, the first push rod 522 has a third slide rail 526, and the second push rod 523 has a second slider 5232, which is installed inside the third slide rail 526. The third slide rail 526 and the second slider 5232 are configured to prevent the first push rod 522, the second push rod 523, the first slider 5231, the first slide rail 535, and the second slide rail 524 from generating dead points during movement.

[0057] Dead point, also known as stop point or special position of drive mechanism 50. When drive mechanism 50 is in the dead point position, its first push rod and second push rod will temporarily lose their definite direction of movement, causing the mechanism to be unable to continue moving as expected. For example, when the direction of the compressive force on the second push rod is collinear with a preset connection, drive mechanism 50 will generate a dead point. Here, the preset connection is the line connecting the projection points of the rotation axes of the first push rod and the second push rod on a preset plane, and the preset plane is perpendicular to the guide plate. Usually, when the guide plate changes its direction of movement, drive mechanism 50 will generate a dead point.

[0058] In this embodiment, by setting a third slide rail 526 and a second slider 5232, the third slide rail 526 guides the second slider 5232, which can prevent the first push rod 522, the second push rod 523, the first slider 5231, the first slide rail 535, and the second slide rail 524 from entering the dead point position during the movement, thereby improving the operational stability of the drive mechanism 50.

[0059] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the third slide 526 is close to the guide plate, and the third slide 526 is an arc-shaped slide. Specifically, the third slide is located between the end of the first push rod 522 near the guide plate and the second slide 524. Correspondingly, the second slider 5232 is located between the end of the second push rod 523 near the guide plate 30 and the first slider 5231.

[0060] Furthermore, the air outlet is located on the front side of the indoor unit 100 of the air conditioner, below the front end of the first push rod 522 and the front end of the second push rod 523. The third slide rail 526 is located diagonally above the second slide rail 524, and the third slide rail is an arc-shaped slide rail with its concave surface facing downwards.

[0061] In this embodiment, the third slide rail 526 and the second slider 5232 are located near the guide plate, which does not increase the length of the first push rod 522, nor does it increase the length of the second push rod. The third slide rail and the second slider are scientifically and rationally designed, with simple structure and easy processing and manufacturing. They can also effectively prevent the drive mechanism 50 from entering a dead position during movement.

[0062] In an alternative embodiment of this utility model, the third slide rail 526 may also be disposed at other positions of the first push rod 522, and correspondingly the second slider 5232 may also be disposed at other positions of the second push rod 523.

[0063] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the housing 10 includes a transmission box 530, and a first push rod 522 and a second push rod 523 are installed inside the transmission box 530. A first slide rail 535 is provided inside the transmission box 530, and a fourth slide rail 534 is also provided inside the transmission box 530. A third slider 5221 is provided on the first push rod 522, and the third slider 5221 slides within the fourth slide rail 534.

[0064] In this embodiment, the first push rod 522 and the second push rod 523 are installed inside the transmission box 530. The transmission box 530 is provided with a fourth slide rail 534. The first push rod 522 slides within the fourth slide rail 534 to push the guide plate 30 to open or close the air outlet. The transmission box 530 serves to protect the first push rod 522 and the second push rod 523, preventing dust from falling on them and affecting their transmission. This extends the service life of the first push rod 522 and the second push rod 523, thereby reducing the operating cost of the indoor air conditioning unit 100.

[0065] In some embodiments of this utility model, such as Figure 4 As shown, the indoor unit 100 of the air conditioner also includes a motor 510. The motor 510 is fixedly mounted on the housing 10; the output end of the motor 510 is connected to the gear 525. In this embodiment, the first push rod 522 and the second push rod 523 are driven to slide and rotate by the motor 510, rack 521, and gear 525. This embodiment uses only one motor to realize the movement and rotation of the guide plate 30, saving the operating cost of the indoor unit 100 of the air conditioner and improving the user experience.

[0066] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the rack 521 is disposed on the side of the first push rod 522 perpendicular to the first direction.

[0067] In some embodiments of this utility model, the motor 510 is fixedly mounted on the transmission box 530.

[0068] In some embodiments of this utility model, such as Figure 4 As shown, the transmission box 530 is formed by the first box body 531 and the second box body 532 being closed together.

[0069] In some embodiments of this utility model, such as Figure 4 and Figure 7 As shown, the inner sides of the first box 531 and the second box 532 are provided with relief grooves 533. The first push rod 522 and the second push rod 523 are disposed in the relief grooves 533. During the movement of the first push rod 522 and the second push rod 523, the groove wall of the relief groove 533 slides and fits against the edges of the first push rod 522 and the second push rod 523, making the connection structure and operation of the first push rod 522 and the second push rod 523 more stable, improving the stability of the transmission mechanism, and thus making the push-out and pull-back of the guide plate 30 smoother.

[0070] In some embodiments of this utility model, such as Figure 3 , Figure 8 and Figure 9 As shown, the housing 10 also includes a connecting plate 60 and a mounting plate 40, with the connecting plate 60 disposed on the rear side of the guide plate 30. The mounting plate 40 is detachably connected to the connecting plate 60. The mounting plate 40 includes a first mounting portion 410 and a second mounting portion 420, with a first push rod 522 rotatably connected to the second mounting portion 420 and a second push rod 523 rotatably connected to the first mounting portion 410.

[0071] In this embodiment, the connecting plate 60 and the mounting plate 40 are detachably connected, that is, the first push rod 522 and the second push rod 523 are detachably connected to the guide plate 30. When the drive mechanism 50 needs to be repaired or replaced, the mounting plate 40 can be removed from the connecting plate 60, which facilitates the repair and replacement of the drive mechanism 50.

[0072] In some embodiments of this utility model, such as Figure 8 As shown, the connecting plate 60 has an opening in the interior of a first slot 610, and a first slot hole 620 is provided on one side wall of the first slot 610. The mounting plate 40 can be inserted into the first slot 610 at least partially, and a first card 450 is connected to the mounting plate 40. A card block extends from the first card 450 at the corresponding position of the first slot hole 620.

[0073] In this embodiment, the connecting plate 60 is provided with a first slot 610 that allows partial or complete insertion of the mounting plate 40. The slot 610 has a first locking hole 620 on its wall. The mounting plate 40 is provided with a first card 450. When the mounting plate 40 is inserted into the first slot 610, the locking block of the first card 450 is inserted into the first locking hole 620. The connecting plate 60 and the mounting plate 40 are snap-fit ​​connected, requiring no complicated tools or skills, and the operation is relatively simple. Furthermore, the snap-fit ​​structure between the connecting plate 60 and the mounting plate 40 can achieve the effect of repeated installation and disassembly without damaging the parts.

[0074] In some embodiments of this utility model, such as Figure 9 As shown, the mounting plate 40 has an opening inside a second slot 430, and a second slot hole is provided on one side wall of the second slot 430. The connecting plate 60 can be inserted into the second slot 430 at least partially, and a second card 630 is connected to the connecting plate 60. The second card 630 is inserted and engaged with the second slot hole 440.

[0075] In this embodiment, the mounting plate 40 is provided with a second slot 430 that allows partial or complete insertion of the connecting plate 60. The second slot 430 has a second locking hole 440 on its wall. A second card 630 is provided on the mounting plate 40. When the mounting plate 40 is inserted into the second slot 430, the second card 630 is inserted into the second locking hole 440. The connecting plate 60 and the mounting plate 40 are snap-fit ​​connected, requiring no complex tools or skills, making operation relatively simple. Furthermore, the snap-fit ​​structure between the connecting plate 60 and the mounting plate 40 allows for repeated installation and disassembly without damaging the parts.

[0076] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the connecting plate 60 has an opening in its interior, forming a first slot 610. A first slot hole 620 is formed on one side wall of the first slot 610. At least a portion of the mounting plate 40 can be inserted into the first slot 610. A first card 450 is connected to the mounting plate 40, and a locking block extends from the first card 450 at a position corresponding to the first slot hole 620. Furthermore, the mounting plate 40 has an opening in its interior, forming a second slot 430. A second slot hole is formed on one side wall of the second slot 430. At least a portion of the connecting plate 60 can be inserted into the second slot 430. A second card 630 is connected to the connecting plate 60, and the second card 630 engages with the second slot hole 440.

[0077] In this embodiment, the connecting plate 60 is provided with a first slot 610 and a second card 630, and the first slot 610 has a first card hole 620 on its groove wall. The mounting plate 40 is provided with a second slot 430 and a first card 450, and the second slot 430 has a second card hole 440 on its groove wall. When installing the connecting plate 60 and the mounting plate 40, the mounting plate 40 is inserted into the first slot 610, at which time the card 450's locking block enters the first card hole 620.
