Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an air guide device and an air conditioner. Background Technology

[0002] When using an air conditioner, it is usually necessary to adjust the direction of the airflow using the air deflector located at the air outlet. The air conditioner includes an air deflector located at the air outlet and a motor that is connected to the air deflector. The motor drives the air deflector to rotate, and the direction of the airflow from the air outlet can be adjusted by rotating the air deflector to different angles.

[0003] During the rotation of the air deflector, the force exerted by the wind on the air deflector changes, and the drive mechanism that drives the air deflector usually has internal gaps, which can easily lead to unstable rotation of the air deflector and uneven speed during the rotation process, thus reducing the user experience. Utility Model Content

[0004] The problem solved by this invention is how to improve the stability of the air guide door rotation and ensure that the air guide door can rotate at a uniform speed, so as to improve the user experience.

[0005] To solve the above problems, this utility model provides an air guiding device, which includes:

[0006] Base;

[0007] The motor is mounted on the base;

[0008] The worm gear is connected to the output shaft of the motor for transmission.

[0009] The worm gear meshes with the worm.

[0010] Connecting element, connecting element is connected to worm gear; and,

[0011] The air guide damper is connected to the connecting piece; when the output shaft of the motor drives the worm gear to rotate, the worm gear drives the air guide damper to rotate through the worm wheel and the connecting piece.

[0012] The motor disclosed herein drives the air guide damper to rotate through a meshing worm and worm wheel. The self-locking function during the meshing process of the worm and worm wheel can be used to improve the stability of the air guide damper's rotation and ensure that the worm can input a constant speed to the worm wheel, thereby ensuring that the worm wheel drives the air guide damper to rotate at a uniform speed, thus improving the user experience.

[0013] In an optional embodiment, the base is provided with a through hole, through which the connector passes and is detachably connected to the air guide damper.

[0014] The connector is detachably connected to the air deflector after passing through the through hole, which makes it easy to remove the air deflector for maintenance and replacement, and also ensures a more compact structural design.

[0015] In an optional implementation, the air deflector is provided with a slot, and the connector is inserted into the slot.

[0016] The plug-in method reduces the difficulty of loading and unloading and improves assembly stability, ensuring that the worm gear can reliably drive the air guide damper to rotate at a constant speed.

[0017] In an optional embodiment, the air guide device further includes a pin connected to the air guide door, and the pin cooperates with the connector to lock the connector in a state of being inserted into the slot.

[0018] By locking the connector in the slot with a pin, the assembly stability between the worm gear and the air deflector can be ensured.

[0019] In an optional embodiment, the air guide device further includes a first support member connected to the base, the worm gear being supported by the first support member and rotatable relative to the first support member about its own axis of rotation; and / or,

[0020] The air guide device also includes a second support member, through which the motor is mounted on the base.

[0021] By using the first support member to support the worm, the stability of the motor-driven worm rotation can be improved, thereby reliably driving the air guide damper to rotate at a uniform speed using the worm and worm wheel.

[0022] The motor is assembled onto the base using a second support member, ensuring both ease of assembly and stability of the motor within the base.

[0023] In an optional embodiment, the worm gear includes a first threaded section, a connecting section, and a second threaded section connected in sequence; the first support member is provided with a first slot; the air guiding device includes two air guide dampers and two worm wheels; one worm wheel meshes with the first threaded section, and the other worm wheel meshes with the second threaded section, the two worm wheels are inserted into the two air guide dampers in a one-to-one correspondence, and the connecting section is rotatably inserted into the first slot; and / or,

[0024] The first support member is spliced ​​with the base to form a shaft hole, and the worm gear is rotatably inserted into the shaft hole.

[0025] By setting multiple threaded sections on the worm gear to mesh with multiple worm wheels simultaneously, multiple worm wheels can be used to drive multiple air guides, thereby reducing the investment in motors, which helps to reduce costs, and ensures the reliability of synchronous rotation of multiple air guides. Moreover, by rotatably inserting the worm gear into the first slot of the first support member, the stability of the worm gear can be improved, thereby stably driving the air guides to rotate.

[0026] The worm gear is rotatably inserted into the shaft hole formed by the splicing of the first support and the base, which helps to ensure the stable rotation of the worm gear, and thus stably drives the air guide damper to rotate at a constant speed through the worm wheel.

[0027] In an alternative embodiment, the first support member is provided with a receiving space, in which at least a portion of the worm gear is received.

[0028] This design allows for a more compact structure while also protecting the worm gear, ensuring that the worm and worm gear work together to stably drive the air guide damper to rotate at a constant speed.

[0029] In an optional implementation, the rotation axis of the worm is perpendicular to the rotation axis of the worm wheel.

[0030] This configuration ensures that the worm gear can only rotate with the worm it meshes with, thereby ensuring a reliable self-locking capability between the worm and the worm gear. This means that the worm gear is not affected by other external forces in its rotation direction, providing a constant rotational drive to the air deflector. This ensures that the air deflector can rotate evenly and constantly. In particular, no matter how the torque of the wind acting on the air deflector changes, or even when it changes direction, the direction of the air deflector's rotational speed will not change, thus ensuring that the air deflector can rotate at a uniform speed.

[0031] In an optional embodiment, the air guide device further includes a crank assembly, and the output shaft of the motor is connected to the worm gear drive through the crank assembly; when the output shaft of the motor rotates in the same direction, it can drive the worm gear to reciprocate around its own rotation axis through the crank assembly.

[0032] By setting up the crank assembly, the motor's output shaft can rotate in only one direction, thus achieving the reciprocating rotation of the air guide damper. This reduces the losses caused by the commutation of the motor's output shaft and helps extend the motor's service life.

[0033] This utility model also provides an air conditioner, including a housing and an air guiding device according to any of the foregoing embodiments; the housing is provided with an air outlet, the base is assembled on the housing, and the air guide door is located at the air outlet, and the air guide door is used to adjust the flow direction of the air blown out from the air outlet.

[0034] The motor of the air conditioner disclosed herein drives the air deflector to rotate through a meshing worm and worm wheel. The self-locking function during the meshing process of the worm and worm wheel can be used to improve the stability of the air deflector rotation and ensure that the worm can input a constant speed to the worm wheel, thereby ensuring that the worm wheel drives the air deflector to rotate at a uniform speed, thus improving the user experience.

Detailed Implementation

[0049] The related technology provides an air conditioner including an air deflector located at the air outlet and a motor connected to the air deflector. The motor drives the air deflector to rotate, thus adjusting the direction of airflow from the air outlet by rotating the air deflector to different angles. The motor typically drives the air deflector directly or through a linkage mechanism. Direct drive or linkage mechanism-driven methods usually suffer from a small adjustable range of transmission ratio. Furthermore, the force exerted by the airflow on the air deflector changes during rotation, and the internal structure of drive mechanisms such as linkage mechanisms often has gaps, which can easily lead to unstable air deflector rotation and uneven speed during rotation, thus reducing the user experience.

[0050] To improve the above issues, please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides an air conditioner 010, which includes an air guide device 200 that can improve the above-mentioned problems; the air guide device 200 and the air conditioner 010 of this embodiment will be described in detail below with reference to the accompanying drawings.

[0051] This embodiment provides an air conditioner 010, which refers to an indoor cabinet air conditioner. The air conditioner 010 includes a housing 100, a heat exchange device (not shown), a fan (not shown), and an air guide device 200. The housing 100 is provided with an air outlet 110, and the heat exchange device and the fan are both assembled inside the housing 100. The air guide device 200 includes an air guide damper 260, which is rotatably disposed at the air outlet 110. The fan is used to blow the air heated by the heat exchange device out of the air outlet 110, and the air guide damper 260 is used to adjust the airflow direction of the air blown out of the air outlet 110, that is, to adjust the air outlet direction to meet the user's needs.

[0052] It should be noted that the air deflector 260 can also be used to close or open the air outlet 110. That is, when the air conditioner 010 is not in use, the air deflector 260 can close the air outlet 110 to reduce dust falling into the air conditioner 010. When the air conditioner 010 is working, the air deflector 260 opens the air outlet 110 to ensure that the air being heated can be blown out from the air outlet 110.

[0053] The structure and working principle of the heat exchanger and fan are similar to those of related technologies, and will not be described in detail here.

[0054] To ensure the air deflector 260 rotates at a uniform speed and stably, thus improving the user experience, please refer to... Figure 4 and Figure 5The air guiding device 200 in this embodiment also includes a base 210, a motor 220, a worm 230, a worm wheel 240, and a connector 250. The base 210 is mounted on the housing 100, the motor 220 is mounted on the base 210, the worm 230 is connected to the output shaft of the motor 220, the worm wheel 240 meshes with the worm 230, and the air guide damper 260 is connected to the worm wheel 240 through the connector 250. When the output shaft of the motor 220 drives the worm 230 to rotate, the worm 230 drives the worm wheel 240 to rotate, and the worm wheel 240 drives the air guide damper 260 to rotate through the connector 250. That is, the worm 230 drives the air guide damper 260 to rotate through the worm wheel 240 and the connector 250. The motor 220 drives the air guide damper 260 to rotate through the meshing worm 230 and worm wheel 240. The self-locking function of the meshing worm 230 and worm wheel 240 can be used to improve the stability of the rotation of the air guide damper 260 and ensure that the worm 230 can input a constant speed to the worm wheel 240, thereby ensuring that the worm wheel 240 drives the air guide damper 260 to rotate at a uniform speed, thus improving the user experience. Moreover, the meshing structure of the worm wheel 240 and worm 230 ensures the compactness of the structure and ensures that the worm 230 and worm wheel 240 move and stop with the motor 220, reducing the problem of abnormal noise caused by collisions between the worm 230 and worm wheel 240 and other components.

[0055] It should be noted that by selecting worm gears 240 with different numbers of teeth and worms 230 with different numbers of helical grooves, the transmission ratio can be adjusted.

[0056] The connection methods between the base 210 and the housing 100 include, but are not limited to, snap-fit ​​connection and connection by fasteners such as bolts.

[0057] It should be noted that the base 210 is the air outlet frame assembled on the housing 100.

[0058] Further, please refer to Figure 5 The base 210 is provided with a through hole 211, and the connector 250 passes through the through hole 211 and is detachably connected to the air guide damper 260. The detachable connection of the connector 250 to the air guide damper 260 after passing through the through hole 211 facilitates the removal of the air guide damper 260 for maintenance and replacement, and also ensures a more compact structural design.

[0059] Furthermore, please refer to Figure 4The rotation axis of the worm 230 is perpendicular to the rotation axis of the worm wheel 240. This arrangement ensures that the worm wheel 240 can only rotate with the worm 230 it meshes with, thereby ensuring a reliable self-locking capability between the worm 230 and the worm wheel 240. That is, it ensures that the worm wheel 240 is not affected by other external forces in its rotation direction, and provides a constant rotational drive to the air guide 260. This ensures that the air guide 260 can rotate uniformly and constantly. In particular, no matter how the torque of the wind acting on the air guide 260 changes, or even when it changes direction, the direction of the rotational speed of the air guide 260 will not change, thus ensuring that the air guide 260 can rotate at a uniform speed.

[0060] Of course, in other embodiments, the rotation axis of the worm 230 and the rotation axis of the worm wheel 240 may have a small angular error, such as 0.1° or 0.3°.

[0061] The connection method between connector 250 and air deflector 260 can be selected as needed; please refer to [reference needed]. Figure 6 In this embodiment, the air guide damper 260 is provided with a slot 261, and the connector 250 is inserted into the slot 261. That is, the connector 250 is a pin, and the pin is inserted into the slot 261. The insertion method reduces the difficulty of installation and removal and improves the assembly stability, so as to ensure that the worm gear 240 can reliably drive the air guide damper 260 to rotate at a uniform speed.

[0062] Of course, in other embodiments, the connection between the connector 250 and the air guide 260 can also be by bonding, welding, or by fasteners such as bolts, etc., and no specific limitation is made here.

[0063] Alternatively, please refer to Figure 6 The air guide device 200 also includes a pin 262, which is connected to the air guide damper 260 and cooperates with the connector 250 to lock the connector 250 in the inserted state with the slot 261. Locking the connector 250 in the inserted state with the slot 261 by the pin 262 can ensure the assembly stability between the worm gear 240 and the air guide damper 260.

[0064] The structure of the pin 262 is similar to that of related technologies, and the pin 262 can lock the assembly between the connector 250 and the air guide 260 by means of plugging, snapping, or interference fit with the connector 250.

[0065] To improve the stability of the worm gear 230 assembled with the base 210; please refer to Figure 4 and Figure 7The air guide device 200 in this embodiment also includes a first support member 270, which is connected to the base 210. The worm gear 230 is supported by the first support member 270 and can rotate relative to the first support member 270 around its own rotation axis. By using the first support member 270 to support the worm gear 230, the stability of the motor 220 driving the worm gear 230 to rotate can be improved, and the worm gear 230 and worm wheel 240 can reliably drive the air guide door 260 to rotate at a uniform speed.

[0066] The connection method between the first support member 270 and the base 210 can be selected as needed; in this embodiment, the first support member 270 is connected to the base 210 by fasteners such as bolts.

[0067] Of course, in other embodiments, the first support member 270 can also be connected to the base 210 by means of bonding, snap-fitting, or other methods.

[0068] To improve the stability of the worm gear 230, please refer to... Figure 4 The first support member 270 is provided with a first slot 271, and the worm gear 230 is rotatably inserted into the first slot 271. By setting the first slot 271, the rotation position of the worm gear 230 is limited, thereby improving the stability of the worm gear 230, and thus improving the stability of the worm gear 230 driving the worm wheel 240 to drive the air guide damper 260 to rotate.

[0069] Furthermore, the base 210 is provided with a second slot 212, and the first support member 270 and the base 210 are spliced ​​together so that the first slot 271 and the second slot 212 are joined to form a shaft hole 272, into which the worm gear 230 is rotatably inserted. In this way, the assembly stability of the worm gear 230 can be further improved, thereby improving the stability of the worm gear 230 driving the worm wheel 240 to drive the air guide damper 260 to rotate.

[0070] It should be noted that the worm 230 has a threaded section and a non-threaded section connected to the threaded section. The above-mentioned worm 230 being rotatably inserted into the shaft hole 272 can mean that the non-threaded section of the worm 230 is rotatably inserted into the shaft hole 272.

[0071] The number of air deflectors 260 in the air guiding device 200 can be selected as needed; please refer to [reference needed]. Figure 7 In this embodiment, the air guiding device 200 includes two air guide dampers 260 and correspondingly two worm gears 240. The two air guide dampers 260 and the two worm gears 240 are connected in a one-to-one transmission connection, and both worm gears 240 mesh with a worm 230. In this way, one motor 220 and one worm 230 can be used to drive the two air guide dampers 260 to rotate, thereby reducing the number of motors 220 and worm gears 230 required, which helps to reduce costs and ensures the reliability of synchronous rotation of multiple air guide dampers 260.

[0072] Furthermore, the worm gear 230 includes a first threaded section 231, a connecting section 233, and a second threaded section 232 connected coaxially in sequence, with the connecting section 233 being a non-threaded section; one worm wheel 240 meshes with the first threaded section 231, and the other worm wheel 240 meshes with the second threaded section 232, while the connecting section 233 is rotatably inserted into the shaft hole 272. Rotatably inserting the connecting section 233 into the shaft hole 272 formed by the first slot 271 and the second slot 212 improves the stability of the worm gear 230, thereby stably driving the air guide damper 260 to rotate.

[0073] Of course, in other embodiments, the connecting segment 233 may also be a threaded segment, which is not specifically limited here.

[0074] Optionally, the worm gear 230 further includes two rotating shaft sections 234. One rotating shaft section 234 is coaxially connected to the end of the first threaded section 231 away from the connecting section 233, and the other rotating shaft section 234 is coaxially connected to the end of the second threaded section 232 away from the connecting section 233. The first support member 270 is provided with three first slots 271, and the base 210 is provided with three second slots 212. The three first slots 271 and the three second slots 212 are arranged one-to-one to form three shaft holes 272. The connecting section 233 and the two rotating shaft sections 234 are rotatably inserted into the three shaft holes 272 respectively. In this way, the assembly stability of the worm gear 230 can be further ensured.

[0075] It should be understood that in other embodiments, the number of air deflectors 260 may be one, three, four, etc., the number of worm gears 240 corresponds to the number of air deflectors 260, and the number of threaded segments of the worm 230 may also correspond to the number of air deflectors 260. Alternatively, the worm 230 may include only one threaded segment, and all worm gears 240 may mesh with the same threaded segment.

[0076] To improve the stability of the motor 220 mounted on the base 210 and ensure the ease of operation of the motor 220 mounted on the base 210; please refer to Figure 4 The air guide device 200 also includes a second support member 280, and the motor 220 is mounted on the base 210 through the second support member 280.

[0077] Optionally, the second support member 280 is provided with an assembly groove, the motor 220 is embedded in the assembly groove, and the output shaft of the motor 220 extends out from the assembly groove. The second support member 280 is connected to the base 210 by bolts or other fasteners. Embedding the motor 220 in the assembly groove can improve the stability of the motor 220 in the second support member 280, and the second support member 280 can also protect the motor 220.

[0078] Of course, in other embodiments, the second support member 280 may not have an assembly slot for embedding the motor 220, and the motor 220 may be assembled to the second support member 280 by fasteners such as bolts; or, in other embodiments, the motor 220 may be directly connected to the base 210 by fasteners such as bolts, which is not specifically limited here.

[0079] Optionally, the air guide device 200 also includes a crank assembly (not shown in the figure), and the output shaft of the motor 220 is connected to the worm gear 230 via the crank assembly. When the output shaft of the motor 220 rotates in the same direction, the crank assembly drives the worm gear 230 to reciprocate around its own axis of rotation. By setting the crank assembly, the output shaft of the motor 220 can rotate in only one direction, thus realizing the reciprocating rotation of the air guide damper 260, reducing the losses caused by the commutation of the output shaft of the motor 220, and helping to extend the service life of the motor 220.

[0080] It should be noted that the structure of the crank assembly is similar to that of related technologies, and will not be described in detail here.

[0081] Of course, in other embodiments, the motor 220 can also directly drive the worm gear 230, and when the output shaft of the motor 220 reciprocates, it can drive the worm gear 230 to reciprocate, and drive the worm wheel 240 to drive the air guide damper 260 to reciprocate through the reciprocating rotation of the worm gear 230.

[0082] It should be understood that in other embodiments, please refer to Figure 8 and Figure 9 Air conditioner 010 can also refer to indoor wall-mounted unit, in which the base 210 of the air guide device 200 is the base; the differences from indoor floor-standing unit will be introduced below.

[0083] Please refer to Figure 10 , Figure 11 and Figure 12 In the embodiment where the air conditioner 010 is an indoor wall-mounted unit, there is one air guide damper 260 and one worm gear 240. One end of the worm 230 is connected to the output shaft of the motor 220 for transmission, and the other end of the worm 230 is inserted into the shaft hole 272 formed by the splicing of the first support member 270 and the base 210. That is, the end of the worm 230 away from the motor 220 is inserted into the shaft hole 272 formed by the splicing of the first slot 271 of the first support member 270 and the second slot 212 of the base 210. The worm gear 240 meshes with the worm 230 and is connected to the air guide damper 260 through the connector 250. When the motor 220 drives the worm 230 to rotate, the worm 230 drives the worm gear 240 to drive the air guide damper 260 to rotate.

[0084] Furthermore, the first support member 270 is provided with a receiving space 273, in which at least a portion of the worm gear 240 is received; specifically, at least a portion of the side of the worm gear 240 facing away from the connector 250 is received in the receiving space 273. This arrangement enables a more compact structural design and provides protection for the worm gear 240, thereby ensuring that the worm 230 and the worm gear 240 cooperate to stably drive the air guide damper 260 to rotate at a uniform speed.

[0085] The assembly process of the air guide device 200 in this embodiment includes: assembling the worm gear 240 and the motor 220 on the base 210; connecting the worm 230 to the output shaft of the motor 220 and engaging the worm 230 with the worm gear 240; assembling the first support member 270 on the base 210 and inserting the worm 230 into the first slot 271 of the first support member 270; and connecting the air guide door 260 and the connecting member 250 that connects the worm gear 240 together.

[0086] In summary, the air guide device 200 of this utility model can be used in air conditioner 010. The air guide device 200 can improve the stability of the rotation of the air guide door 260 and ensure that the air guide door 260 rotates at a uniform speed, thereby improving the user experience.

[0087] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
