[0050] Figure 1 is a schematic structural diagram of a key dialing device according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 6 The embodiment of the utility model provides a key-dial device 100 for an air conditioner, comprising a support base 10, a key-dial 20, a button 40 and a torsion spring 50. The key-dial 20 is rotatably mounted on the support base 10 via a rotating shaft 30, and the rotating shaft 30 is disposed on the support base 10 or on the key-dial 20. The button 40 is configured to receive the pressing of the key-dial 20 when the key-dial 20 rotates to one side. The torsion spring 50 comprises a spring coil portion 510 and two arms 520 connected to the spring coil portion 510. The spring coil portion 510 is sleeved on the rotating shaft 30. Two arms 520 are disposed on both sides of the spring coil portion 510, and each arm 520 is in contact with or connected to both the dial key 20 and the support seat 10, so that when the dial key 20 is moved toward one side of the dial key 20, one of the two arms 520 acts on the support seat 10, and the other acts on the dial key 20, so that the torsion spring 50 accumulates force, and then the torsion spring 50 causes the dial key 20 to reset.

[0051] In this embodiment, the dial key 20 is rotatably mounted on the support seat 10, the torsion spring 50 is mounted on the dial key 20 or the support seat 10, and the two arms 520 of the torsion spring 50 are connected or in contact with the dial key 20 and the support seat 10. When the dial key 20 is dialed, one arm 520 on one side of the rotation direction of the dial key 20 rotates, and the support seat 10 blocks the rotation of the arm 520, so that the torsion spring 50 accumulates force. After the dial key 20 is released, the torsion spring 50 releases the elastic force, prompting the dial key 20 to rotate in the opposite direction of the dialing, thereby realizing the automatic reset of the dial key 20. The dial key device 100 in this embodiment utilizes the elastic effect of the torsion spring 50 to solve the problem of the dial key 20 not being reset in place after being dialed, and ensures that the dial key 20 is normally reset after being dialed. In addition, the two arms 520 of the torsion spring 50 are on both sides of the dial key 20, and the two arms 520 are connected or in contact with the dial key 20 and the support seat 10, so that the dial key 20 is reset to the center position.

[0052] In some embodiments of the present invention, Figure 2 As shown, each arm 520 has a first action position 521 and a second action position 522, wherein the first action position 521 is between the second action position 522 and the spring coil 510. The first action position 521 contacts or is connected to the dial key 20, and the second action position 522 contacts or is connected to the support seat 10.

[0053] In this embodiment, the portion of the support arm 520 that contacts or connects with the dial key 20 is the first action position 521, and the portion of the support arm 520 that contacts or connects with the support base 10 is the second action position 522. When the dial key 20 is turned, one of the support arms 520 on the side of the rotation direction of the dial key 20 rotates, and the second action position 522 is subjected to a force that prevents the support arm 520 from rotating, thereby storing force in the torsion spring 50. After the dial key 20 is released, the torsion spring 50 releases its elastic force, causing the dial key 20 to rotate in the opposite direction of the turning, thereby realizing automatic resetting of the dial key 20.

[0054] In some embodiments of the present invention, Figure 2 As shown, the first action position 521 contacts the dial key 20 , the second action position 522 contacts the support base 10 , and the two first action positions 521 and the two second action positions 522 are located on the same side of the corresponding contact positions on the dial key 20 and the support base 10 .

[0055] In this embodiment, the first action position 521 and the second action position 522 are located on the same side of the dial key 20 and the support base 10, so that when the dial key 20 is turned, the torsion spring 50 is subjected to resistance in the same direction, so that the torsion spring 50 accumulates force, and after the dial key 20 is released, the torsion spring 50 releases the force to automatically reset the dial key 20.

[0056] Furthermore, the two first action positions 521 and the two second action positions 522 are located in front of corresponding contact positions on the dial key 20 and the support base 10 .

[0057] In some embodiments of the present invention, Figure 2 and 5 As shown, the dial key 20 includes a main body 210 and a first support portion 220. The main body 210 is rotatably mounted on the support base 10 via a rotating shaft 30. The first support portion 220 is disposed on the main body 210, and two support positions 230 are disposed on the first support portion 220, each of which is in contact with a first action position 521 of a support arm 520. The support base 10 includes two second support portions 110, and the two second support portions 110 are disposed on both sides of the two support positions 230, and each of the second support portions 110 is in contact with a second action position 522 of a support arm 520. In this embodiment, the first support portion 220 supports the first action position 521, and the second support portion 110 supports the second action position 522.

[0058] In some embodiments of the present invention, Figure 5 As shown, a first groove 240 is formed at each supporting position 230 , a second groove 120 is provided at the position where each second supporting portion 110 contacts the second action position 522 , and each support arm 520 passes through the corresponding first groove 240 and second groove 120 .

[0059] In this embodiment, a groove is provided at the support position 230 where the first support portion 220 and the second support portion 110 contact the support arm 520 of the torsion spring 50. In the groove, the support arm 520 is not easy to move when subjected to force, so that the torsion spring 50 is more stable in the force storage state, thereby preventing the key 20 from shaking and causing instability of the key device 100.

[0060] In some embodiments of the present invention, the two first action positions 521 and the two second action positions 522 are located in the same plane.

[0061] In this embodiment, the first action position 521 and the second action position 522 are in the same plane, so as to prevent the arm 520 of the torsion spring 50 from being lifted and unable to rest on the first support portion 220 or the second support portion 110, to prevent the dial key 20 from shaking left and right and unable to be centered in a free state, or to prevent the dial key 20 from being unable to drive the torsion spring 50 to move while rotating, resulting in a reduction in the compression amount and elasticity of the torsion spring 50.

[0062] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the rotating shaft 30 is disposed on the dial key 20 and is rotatably mounted on the supporting base 10 .

[0063] In some embodiments of the present invention, Figure 3 As shown, there are two buttons 40, which are arranged on both sides of the dial key 20, and the buttons 40 contact and abut against the corresponding side of the dial key 20. The buttons 40 are elastic buttons with a self-reset function.

[0064] In this embodiment, the buttons 40 are arranged on both sides of the dial key 20, and the buttons 40 on both sides support both sides of the dial key 20, so that the dial key 20 is in a central position in a free state, and then the dial key 20 can be reset to the central position after the dial key 20 is dialed. In addition, the button 40 is elastic, and after the dial key 20 is released, the elasticity of the button 40 causes the button 40 to bounce up, and the side of the dial key 20 that abuts against the button 40 also rotates in the direction of the button 40 bouncing up under the action of the button 40, further causing the dial key 20 to automatically reset to the central position after being dialed.

[0065] In some embodiments of the present invention, Figure 3 As shown, a pressure rod 60 is provided between the button 40 and the corresponding side of the dial key 20, and the pressure rod 60 contacts and abuts against the corresponding side of the button 40 and the dial key 20, so that one button 40 is pressed by the dial key 20 when the dial key 20 rotates to one side, and the other button 40 is pressed by the dial key 20 when the dial key 20 rotates to the other side.

[0066] In this embodiment, a pressure rod 60 is provided between the button 40 and the dial key 20. When the dial key 20 is turned, one side of the dial key 20 presses the pressure rod 60, and the pressure rod 60 presses the button 40. By providing the pressure rod 60 between the button 40 and the dial key 20, when the distance between the dial key 20 and the button 40 is large, the pressure rod 60 moving up and down transmits force, which facilitates the pressing of the button 40 by the dial key 20, and can avoid the slow rebound of the button 40 caused by the excessive length of the button 40, so that the key dialing device 100 is more accurate.

[0067] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the key-dial device 100 further includes a key base 41 , and two keys 40 are disposed on the key base 41 . The key base 41 and the two keys 40 are integrally formed, and the key base 41 and the two keys 40 are both made of rubber.

[0068] In this embodiment, the key 40 and the key seat 41 are integrally formed, which is convenient for fixing the positions of the two keys 40, preventing the positions of the two keys 40 from moving and affecting the normal operation of the key dialing device 100. In addition, the integrally formed key 40 and key seat 41 are more convenient to produce and reduce production costs.

[0069] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the key-dial device 100 further includes a push rod 70 and a reset device 80. The push rod 70 is movably mounted on the support seat 10 along its length direction. The end of the push rod 70 facing the key 20 is provided with a support head 710. The key 20 is provided with a positioning groove 250 that cooperates with the support head 710. The moving direction of the support head 710 is perpendicular to the rotation axis of the key 20. In the moving direction of the support head 710 moving toward the key 20, the rotation axis of the key 20 and the positioning groove 250 are sequentially arranged. The reset device 80 causes the support head 710 to be inserted into the positioning groove 250 through the push rod 70.

[0070] In this embodiment, the push rod 70 moves in a direction perpendicular to the rotation direction of the dial key 20. In the direction in which the push rod 70 moves toward the dial key 20, the reset device 80, the push rod 70 and the positioning groove 250 are respectively arranged. When the dial key 20 is released, the reset device 80 prompts the push rod 70 to move in the direction of the dial key 20, so that the support head 710 is inserted into the positioning groove 250. The push rod 70 pushes up the dial key 20 through the reset device 80, so that the dial key 20 can be automatically reset after being dialed. Moreover, since the push rod 70 can only move in a direction perpendicular to the rotation direction of the dial key 20, when the support head 710 is inserted into the positioning groove 250, the dial key 20 is in a central position, so that the dial key 20 is reset to the central position after being dialed.

[0071] In some embodiments of the present invention, Figure 3 As shown, the support head 710 is a ball head or a remaining structure after a part of the ball head is removed. Alternatively, the support head 710 is a support column parallel to the rotation axis of the dial key 20, and the cross section of the support column is circular, arched or fan-shaped.

[0072] In this embodiment, the support head 710 has a curved surface inserted into the positioning groove 250 , so that the support head 710 can position the dial key 20 and does not affect the rotation of the dial key 20 when the dial key 20 rotates.

[0073] In some embodiments of the present invention, the reset device 80 is a compression spring.

[0074] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the main body 210 includes an extrusion block 211, a shift block 212 and two end plates 213. The two side surfaces of the extrusion block 211 are concave and convex respectively, so that the extrusion block 211 is curved. The extrusion block 211 is configured as an extrusion button 40. The shift block 212 is arranged on the convex surface of the extrusion block 211, and the positioning groove 250 is arranged on the concave surface of the extrusion block 211.

[0081] In this embodiment, when the dial key 20 is turned, one side of the dial key 20 presses the corresponding pressure rod 60, the torsion spring 50 on the dial key 20 accumulates force, and the compression spring is compressed. After the dial key 20 is released, the torsion spring 50 releases the elastic force, and the dial key 20 automatically resets under the elastic action of the torsion spring 50. After the dial key 20 is released, the compression spring stretches, and the push rod 70 moves in the direction of the dial key 20 under the elastic force of the compression spring, pushing the dial key 20 out, further promoting the automatic reset of the dial key 20. After the dial key 20 is released, the button 40 pops up, causing one side of the dial key 20 to rotate toward the initial position, further promoting the automatic reset of the dial key 20. The support head 710 of the push rod 70 is inserted into the positioning groove 250 of the dial key 20 to achieve the positioning of the dial key 20 and ensure that the dial key 20 is in the center position.

[0082] The embodiment of the utility model further provides an air conditioner, comprising the key dial device 100 in any one of the above embodiments.

[0083] In this embodiment, the dial key device 100 can solve the problem that the dial key 20 fails to reset after being turned, and ensures that the dial key 20 resets normally and resets to the center position after being turned, thereby improving the user experience of using the air conditioner.
