[0044] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0045] Currently, the air volume of the air conditioner is usually adjusted by the speed of the motor. However, the air volume adjusted by the motor has an upper limit and a lower limit, and cannot meet higher or lower air volumes, resulting in a poor user experience.

[0046] Based on the above questions, please refer to Figures 1 to 6 The present invention provides an air conditioner 10, which includes a base 100, a wind wheel 200, a volute 300, a driving member 400 and a transmission mechanism 500.

[0047] The wind wheel 200, the volute tongue 300, the driving member 400 and the transmission mechanism 500 are all provided with a base 100;

[0048] The volute tongue 300 is movably disposed on the wind wheel 200. The driving member 400, the transmission mechanism 500 and the volute tongue 300 are connected in sequence. The driving member 400 is used to drive the transmission mechanism 500 to move within a preset range of motion so that the transmission mechanism 500 drives the volute tongue 300 to move closer to or away from the wind wheel 200.

[0049] In this embodiment, the driving member 400 drives the transmission mechanism 500 to drive the entire volute tongue 300 or at least part of the volute tongue 300 close to the wind wheel 200, thereby reducing the distance between the volute tongue 300 and the wind wheel 200, thereby increasing the air volume; or drives the volute tongue 300 or at least part of the volute tongue 300 away from the wind wheel 200, thereby increasing the distance between the volute tongue 300 and the wind wheel 200, thereby reducing the air volume. Therefore, by adjusting the distance between the volute tongue 300 and the wind wheel 200, the air volume of the air conditioner 10 can be effectively increased or decreased to meet the user's usage needs.

[0050] In detail, the driving member 400 is a motor, and the transmission mechanism 500 can be, but is not limited to, a connecting rod 530 mechanism, a crank mechanism, and a cylinder. The transmission mechanism 500 can move within a fixed preset range under the driving action of the driving member 400, thereby driving the volute tongue 300 to rotate a preset angle relative to the wind wheel 200, thereby changing the distance between the volute tongue 300 and the wind wheel 200.

[0051] It is understandable that the volute tongue 300 can move as a whole relative to the wind wheel 200 driven by the driving member 400 and the transmission mechanism 500, or only part of the structure can move, as long as the distance between the volute tongue 300 and the wind wheel 200 can be changed to increase or decrease the air output, and no specific limitation is made here.

[0052] It should be noted that the base 100 includes a volute, and a wind wheel 200 is installed in the volute; and the volute includes a front volute tongue and a rear volute tongue, and the volute tongue 300 is the front volute tongue on the side of the hanging plate away from the base, so that the volute tongue 300 can be driven by the driving member 400 and the transmission mechanism 500 to rotate relative to the base 100, and approach or move away from the wind wheel 200, ultimately achieving an increase or decrease in the air output.

[0053] Furthermore, the base 100 is provided with a plurality of positioning portions 110 arranged in sequence, and the driving member 400 is used to drive the transmission mechanism 500 to rotate and to be fixedly matched with any positioning portion 110 .

[0054] In this embodiment, the positioning parts 110 are arranged in a straight line, so the transmission mechanism 500 moves within the straight range of the positioning parts 110 and is fixedly matched with the positioning parts 110, and the transmission mechanism 500 is fixedly matched with the positioning parts 110 located at the two ends to correspond to the maximum or minimum rotation angle of the volute tongue 300, and the fixed cooperation between the transmission mechanism 500 and other fixed parts can make the volute tongue 300 rotate to other angles. Therefore, by setting a plurality of positioning parts 110, the volute tongue 300 can have a plurality of rotation angles, so as to realize that the air output has the same number of gears as the positioning parts 110, thereby increasing the air output range of the air output and improving the user's usage needs.

[0055] Specifically, the positioning portion 110 is a groove 313, the transmission mechanism 500 includes a movable part 510 and a transmission rod 520 connected to each other, the movable part 510 is rotatably arranged on the base 100, the volute 300 is connected to the transmission rod 520, and the driving part 400 is used to drive the transmission rod 520 to move and embed into any groove 313.

[0056] In this embodiment, by setting the positioning portion 110 as a groove 313, the driving member 400 can drive the transmission rod 520 to move and then be firmly embedded in the groove 313, thereby ensuring that the volute tongue 300 is maintained at a fixed angle, improving structural stability, and ensuring consistent air output.

[0057] Specifically, the number of the grooves 313 is three, and the three grooves 313 correspond to the maximum air volume, the default air volume, and the minimum air volume, respectively.

[0058] Furthermore, the movable member 510 is provided with a through slot 511 , and the end of the volute tongue 300 is provided with a sliding block 311 , and the sliding block 311 is slidably matched with the sliding slot.

[0059] In this embodiment, the volute tongue 300 is inserted into the through groove 511 of the movable part 510 through the slider 311, which is convenient for installation or disassembly and realizes a stable connection between the end of the volute tongue 300 and the movable part 510, so that the volute tongue 300 can be driven by the movable part 510 to rotate relative to the wind wheel 200.

[0060] Furthermore, the volute tongue 300 is also provided with a clamping portion 312, the slider 311 is arranged on both sides of the clamping portion 312, the movable part 510 is provided with a clamping slot 512, the through slot 511 is arranged on two side walls of the clamping slot 512, the clamping portion 312 is clamped with the clamping slot 512, and the slider 311 is embedded in the through slot 511.

[0061] In this embodiment, the volute tongue 300 is assembled with the slot 512 of the movable part 510 through the clamping portion 312, and the slider 311 is inserted into the slide groove when the clamping portion 312 is embedded in the slot 512, thereby facilitating the assembly of the volute tongue 300 and the movable part 510.

[0062] Furthermore, the transmission mechanism 500 further includes at least two connecting rods 530, and the driving member 400, at least two connecting rods 530 and the transmission rod 520 are hinged in sequence.

[0063] In this embodiment, there are two connecting rods 530, one end of one connecting rod 530 is connected to the output end of the driving member 400, and the other end is hinged to another connecting rod 530, and the other connecting rod 530 is hinged to the transmission rod 520 to drive the two connecting rods 530 and the transmission rod 520 to move through the driving member 400.

[0064] Of course, in other embodiments, the number of connecting rods 530 can be other settings, as long as it can drive the transmission member to move under the drive of the driving member 400 and can be fixedly matched with the fixing part, and no specific limitation is made here.

[0065] Furthermore, the transmission mechanism 500 further includes a fixing member 540 , which is disposed on the base 100 , and the movable member 510 is hinged to the fixing member 540 .

[0066] In this embodiment, the fixing member 540 is fixed on the base 100 and the fixing member 540 is hinged to the movable member 510 so that the movable member 510 can rotate relative to the base 100 under the action of the transmission rod 520, thereby driving the volute 300 connected to the movable member 510 to rotate relative to the wind wheel 200.

[0067] Furthermore, the volute tongue 300 includes a first shell 310 and a second shell 320. The first shell 310 is located on one side of the wind wheel 200 to form a wind guide wall. The second shell 320 is connected to the base 100. The first shell 310 and the second shell 320 are rotatably connected.

[0068] In this embodiment, the clamping portion 312 is arranged at the end of the first shell 310 away from the second shell 320. Therefore, by making the first shell 310 and the second shell 320 rotatably connected, when the driving member 400 drives the transmission mechanism 500 to move and drives the movable member 510 to rotate, the rotating member drives the first shell 310 to rotate relative to the second shell 320 around the connection portion between the first shell 310 and the second shell 320, so that the distance between the first shell 310 and the wind wheel 200 is increased or decreased, thereby achieving the purpose of changing the air output.

[0069] Furthermore, a groove 313 is provided on the edge of the first shell 310 , and a convex strip 321 and a buckle 322 are respectively provided on the edges at both ends of the second shell 320 . The convex strip 321 is rotatably matched with the groove 313 , and the buckle 322 is buckled with the base 100 .

[0070] In this embodiment, the second shell 320 is clamped to the base 100 through the buckle 322, and the first shell 310 is connected to the movable part 510 of the base 100 through the clamping part 312, so that the volute 300 is assembled to the base 100; and the first shell 310 and the second shell 320 are connected by the convex strip 321 and the groove 313, so that the first shell 310 and the second shell 320 can rotate relative to each other.

[0071] Optionally, in other embodiments, a rotation axis may be further provided between the first shell 310 and the second shell 320 , as long as the relative rotation between the first shell 310 and the second shell 320 can be achieved, which is not specifically limited herein.

[0072] For further information, see Figure 7 The present invention also provides a control method for controlling the air conditioner 10 in the above embodiment, and the control method comprises the following steps:

[0073] Step S100, receiving an interaction instruction input by a user;

[0074] In this embodiment, the air conditioner 10 generally includes a matching remote controller, and the user can interact with the air conditioner 10 through the remote controller, and the controller arranged in the air conditioner 10 receives the interaction instructions input by the user in the remote controller to obtain the user's usage requirements.

[0075] Step S200, generating a control instruction according to the interaction instruction;

[0076] In this embodiment, after receiving the interaction instruction, a corresponding control instruction is generated according to the interaction instruction, and the air conditioner 10 is controlled thereby.

[0077] Step S300 , controlling the driving member 400 to move according to the control instruction, so as to drive the transmission mechanism 500 to move within a preset range of motion, so that the transmission mechanism 500 drives the volute 300 to move closer to or away from the wind wheel 200 .

[0078] In this embodiment, a high wind button, a default button and a low wind button may be provided on the remote control. When the user wants to experience a large wind volume, the user may press the high wind button, and the controller may receive the control instruction corresponding to the high wind gear transmitted by the remote control, and control the movement of the driving member 400 according to the control instruction; it can be understood that the movement of the driving member 400 may be clockwise and counterclockwise; for example, the driving member 400 rotates counterclockwise to drive the connecting rod 530 and the transmission rod 520 to rise, and the transmission rod 520 is fixedly matched with the fixing part located at the top to drive the movement of the volute tongue 300, so that the distance between the volute tongue 300 and the wind wheel 200 is smaller, thereby increasing the air output.

[0079] Similarly, when the user wants to experience a small wind volume, the user can press the small wind button, and the controller can receive the control instruction corresponding to the small wind gear transmitted by the remote control, and control the movement of the driving member 400 according to the control instruction; for example, the driving member 400 rotates clockwise to drive the connecting rod 530 and the transmission rod 520 to move downward, and the transmission rod 520 is fixedly matched with the fixed part located at the bottom to drive the volute tongue 300 to move, so that the distance between the volute tongue 300 and the wind wheel 200 is larger, thereby reducing the air output.

[0080] When the user presses the default button, the controller controls the driving member 400 to drive the volute 300 back to the initial state position according to the instruction.

[0081] In summary, the embodiment of the present invention provides an air conditioner 10 and a control method, wherein the driving member 400 drives the transmission mechanism 500 to drive the entire volute tongue 300 or at least part of the volute tongue 300 to approach the wind wheel 200, thereby reducing the distance between the volute tongue 300 and the wind wheel 200, thereby increasing the air volume; or drives the volute tongue 300 or at least part of the volute tongue 300 away from the wind wheel 200, thereby increasing the distance between the volute tongue 300 and the wind wheel 200, thereby reducing the air volume. Therefore, by adjusting the distance between the volute tongue 300 and the wind wheel 200, the air volume of the air conditioner 10 can be effectively increased or decreased, thereby meeting the user's usage requirements.

[0082] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
