Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an embedded air conditioner. Background Art

[0002] At present, embedded air conditioners are used in large spaces such as shopping malls, large venues, offices, and classrooms. They are usually installed on the ceiling. They are widely favored by users for their small footprint, large radiation area, and good cooling / heating effects. The dust filter on the air inlet grille of the embedded air conditioner will be full of dust after the air conditioner has been running for a period of time. It must be removed and cleaned, otherwise it will affect the efficiency and service life of the air conditioner, and cause dust pollution to the surrounding environment, which will have adverse effects on the health of people living in the space. Since the ceiling or ceiling of the embedded air conditioner installation site is relatively high, the embedded air conditioner is high from the ground and cannot be reached by people. Therefore, when cleaning the embedded air conditioner, the air inlet grille needs to be lowered through the lifting mechanism inside the embedded air conditioner.

[0003] The related technology discloses a lifting mechanism, including a motor, a wire wheel and a rope. There are four lifting mechanisms, which are respectively arranged at the four corners of the air outlet of the air conditioner.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Although the related technology can realize the automatic lifting function of the air inlet grille, it needs to set up four lifting mechanisms to realize it. Each lifting mechanism is equipped with a motor for driving, which easily leads to inconsistent lifting speeds of the four end corners of the air inlet grille, thereby causing the air inlet grille to tilt and scatter dust.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0045] Combination Figure 1-9As shown, the embodiment of the present disclosure provides an embedded air conditioner 10, including a face frame 20, an air inlet grille 30 and a lifting module 40. The face frame 20 defines an installation space 21. The air inlet grille 30 is disposed in the installation space 21, and the air inlet grille 30 includes a first end 31 and a second end 32 that are arranged opposite to each other. The lifting module 40 is disposed in the face frame 20 and connected to the air inlet grille 30, and the lifting module 40 is configured to control the air inlet grille 30 to rise or fall relative to the face frame 20. The lifting module 40 includes a first winding gear 41, a second winding gear 42 and a motor 43, and the first winding gear 41 is connected to the motor 43 and meshed with the second winding gear 42. The lifting module 40 also includes a first traction line and a second traction line, the first traction line is wound around the outer periphery of the first winding gear 41 and connected to the first end 31, and the second traction line is wound around the outer periphery of the second winding gear 42 and connected to the second end 32. The motor 43 drives the first winding gear 41 to rotate, and then drives the second winding gear 42 to rotate, so that the lifting speeds of the first traction line and the second traction line are the same, and thus the lifting speeds of the first end 31 and the second end 32 are the same.

[0046] In the embedded air conditioner 10 provided by the embodiment of the present disclosure, the first wire winding gear 41 is meshed with the second wire winding gear 42, and the motor 43 drives the first wire winding gear 41 to rotate. Therefore, the first wire winding gear 41 and the second wire winding gear 42 are controlled by the same motor 43, and the linear speed of the first wire winding gear 41 is the same as the linear speed of the second wire winding gear 42. Since the first traction line is wound on the first wire winding gear 41 and the second traction line is wound on the second wire winding gear 42, the moving speeds of the first traction line and the second traction line are the same, so the lifting speed of the first end 31 of the air inlet grille 30 connected to the first traction line and the lifting speed of the second end 32 of the air inlet grille 30 connected to the second traction line are also the same. In this way, during the automatic lifting process of the air inlet grille 30, the lifting speeds of the first end 31 and the second end 32 that are relatively set are the same, which prevents the air inlet grille 30 from tilting and sprinkling dust, thereby improving the user experience.

[0047] Optionally, the first winding gear 41 includes a first winding portion 411, and the first winding portion 411 is connected to the motor 43. The first traction line is wound around the outer periphery of the first winding portion 411 and connected to the first end 31, and the motor 43 drives the first winding portion 411 to rotate to reel in or release the first traction line, thereby driving the first end 31 of the air inlet grille 30 to rise or fall relative to the face frame 20.

[0048] In this way, the motor 43 drives the first winding portion 411 to rotate, and reels or releases the first traction wire wound around the outer periphery of the first winding portion 411, thereby driving the air inlet grille 30 connected to the first traction wire to move up and down.

[0049] Optionally, the motor 43 is connected to the rotating shaft of the first winding part 411 , and a cavity is provided at one end of the rotating shaft of the first winding part 411 facing the motor 43 . The motor 43 includes a driving part 431 , and the driving part 431 is inserted into the cavity.

[0050] In this way, the driving part 431 inserted into the cavity can drive the rotating shaft of the first winding part 411 to rotate, thereby driving the first winding part 411 to rotate, so as to reel in or release the first traction line wound on the outer periphery of the first winding part 411, thereby driving the air inlet grille 30 connected to the first traction line to move up and down.

[0051] Optionally, the lifting module 40 further includes a transmission mechanism box 48, the first winding gear 41 and the second winding gear 42 are arranged in the transmission mechanism box, and the motor 43 and the transmission mechanism box 48 are fixed by screws.

[0052] In this way, the first winding gear 41 and the second winding gear 42 are accommodated in the transmission mechanism box 48, and the appearance is neat and beautiful. The motor 43 is fixed to the outside of the transmission mechanism box 48 by screws, and the connection is simple.

[0053] Optionally, the first winding gear 41 also includes a first gear portion 412 that is transmission-connected to the first winding portion 411. The second winding gear 42 includes a second gear portion 422 and a second winding portion 421. The second gear portion 422 is meshed with the first gear portion 412, and the second winding portion 421 is transmission-connected to the second gear portion 422. The second traction line is wound around the outer periphery of the second winding portion 421 and connected to the second end 32. The motor 43 drives the first winding portion 411 to rotate, driving the first gear portion 412 to rotate, and then driving the second gear portion 422 to rotate. The rotation of the second gear portion 422 can drive the second winding portion 421 to rotate, so as to reel in or release the second traction line, thereby driving the second end 32 of the air inlet grille 30 to rise or fall relative to the face frame 20.

[0054] The first gear part 412 is connected to the first winding part 411 by transmission, the second gear part 422 is meshed with the first gear part 412, and the second winding part 421 is connected to the second gear part 422 by transmission. In this way, when the first winding part 411 rotates under the drive of the motor 43, the first winding part 411 can drive the first gear part 412 to rotate, and the rotation of the first gear part 412 drives the second gear part 422 meshed with the first gear part 412 to rotate, thereby driving the second winding part 421 to rotate, and the second traction line is wound or released. The linear speeds of the first winding part 411, the first gear part 412, the second gear part 422 and the second winding part 421 are consistent. In this way, the lifting speeds of the first end 31 and the second end 32 of the air inlet grille 30 are also consistent, which avoids the air inlet grille 30 from being shed due to tilting during the lifting process, thereby improving the user experience. Moreover, only a single motor 43 is needed to drive the first end 31 and the second end 32 of the air inlet grille 30, which is easy to operate. In addition, the transmission of the first gear portion 412 and the second gear portion 422 can reduce the speed of the motor 43 and achieve a controllable lifting speed.

[0055] Optionally, combined Figures 1 to 9 As shown, the first gear portion 412 includes a first rotating shaft 4121, and a first groove 4111 is provided on the surface of the first winding portion 411 facing the first rotating shaft 4121. The first rotating shaft 4121 is inserted into the first groove 4111 so that the first gear portion 412 can be driven to rotate when the first winding portion 411 rotates.

[0056] In this way, the first gear portion 412 and the first winding portion 411 are connected by the cooperation of the first rotating shaft 4121 and the first groove 4111. When the first winding portion 411 rotates, the first groove 4111 drives the first rotating shaft 4121 to rotate, thereby driving the first gear portion 412 to rotate.

[0057] Optionally, the first rotating shaft 4121 is cylindrical, and both ends of the cylindrical first rotating shaft 4121 are chamfered.

[0058] During the process of assembling the first rotating shaft 4121 into the first groove 4111 , the chamfering facilitates the assembly.

[0059] Optionally, the second gear portion 422 includes a second rotating shaft 4221 , a second groove 4211 is provided on the surface of the second winding portion 421 facing the second rotating shaft 4221 , and the second rotating shaft 4221 is inserted into the second groove 4211 , so that the second winding portion 421 can be driven to rotate when the second gear portion 422 rotates.

[0060] In this way, the second gear portion 422 and the second winding portion 421 are connected by the cooperation of the second rotating shaft 4221 and the second groove 4211. When the second gear portion 422 rotates, the second rotating shaft 4221 drives the second groove 4211 to rotate, thereby driving the second winding portion 421 to rotate.

[0061] Optionally, the second rotating shaft 4221 is cylindrical, and both ends of the cylindrical second rotating shaft 4221 are chamfered.

[0062] When the second rotating shaft 4221 is assembled into the second groove 4211 , the chamfering makes assembly easier.

[0063] Optionally, when the first gear portion 412 includes the first rotating shaft 4121, the first gear portion 412 further includes a first position limiting portion 4122. The first position limiting portion 4122 is disposed on the outer periphery of the first rotating shaft 4121 and abuts against the outer periphery of the notch of the first groove 4111 to limit the first groove 4111 from moving beyond the first position limiting portion 4122 and further toward the first gear portion 412.

[0064] In this way, the first limiting portion 4122 abuts against the outer peripheral side of the notch of the first groove 4111 , limiting the first rotating shaft 4121 from moving toward the groove bottom of the first groove 4111 during rotation to increase friction, etc., thereby protecting the motor 43 .

[0065] Optionally, when the second gear portion 422 includes the second rotating shaft 4221, the second gear portion 422 further includes a second limiting portion 4222. The second limiting portion 4222 is disposed on the outer periphery of the second rotating shaft 4221 and abuts against the outer periphery of the notch of the second groove 4211 to limit the second groove 4211 from moving beyond the second limiting portion 4222 toward the second gear portion 422.

[0066] In this way, the second limiting portion 4222 abuts against the outer peripheral side of the notch of the second groove 4211 , limiting the second rotating shaft 4221 from moving toward the groove bottom of the second groove 4211 during rotation to increase friction, etc., thereby protecting the motor 43 .

[0067] Optionally, combined Figures 1 to 9 As shown, the lifting module 40 further includes a first wire wheel 44, which is disposed between the first winding gear 41 and the first end 31, and is configured to guide the first traction line to move up and down along a preset path. The first wire wheel 44 includes a first wire portion 441, wherein a rough structure is disposed on the outer periphery of the first wire portion 441, and the first traction line is wound around the rough structure of the first wire portion 441.

[0068] The first wire wheel 44 is used to rotate the wire feed, so as to prevent the first traction wire from cutting the face frame 20 or the air inlet grille 30 during the movement.

[0069] A rough structure is provided on the periphery of the first wire portion 441 to increase the friction between the first traction wire and the first wire portion 441 , so that when the first traction wire is wound or released by the first winding portion 411 , the first traction wire moves to drive the first wire wheel 44 to rotate.

[0070] Optionally, the rough structure is striae.

[0071] In this way, by providing leather grain on the outer peripheral surface of the first wire portion 441, the friction between the first wire portion 441 and the first traction line is increased. The leather grain has a simple structure and does not need to be connected to other components. The process difficulty is low and cost can be saved.

[0072] Optionally, the lifting module 40 further includes a second wire wheel 45, which is disposed between the second winding gear 42 and the second end 32, and is configured to guide the second traction wire to move up and down along a preset path. The second wire wheel 45 includes a second wire portion 451, wherein a rough structure is disposed on the outer periphery of the second wire portion 451, and the second traction wire is wound around the rough structure of the second wire portion 451.

[0073] The second wire wheel 45 is used to rotate the wire feeding, so as to prevent the second traction wire from cutting the face frame 20 or the air inlet grille 30 during the movement.

[0074] A rough structure is provided on the outer periphery of the second wire portion 451 to increase the friction between the second traction wire and the second wire portion 451 , so that when the second traction wire is wound or released by the second winding portion 421 , the second traction wire moves to drive the second wire wheel 45 to rotate.

[0075] Optionally, the rough structure is striae.

[0076] In this way, by providing leather grain on the outer peripheral surface of the second wire portion 451, the friction between the second wire portion 451 and the second traction wire is increased. The leather grain has a simple structure and does not need to be connected to other components. The process difficulty is low and cost can be saved.

[0077] Optionally, the first wire wheel 44 further includes a first truncated cone 442 and a second truncated cone 443, and the first wire portion 441 is disposed between the first truncated cone 442 and the second truncated cone 443. The first truncated cone 442 and the second truncated cone 443 are coaxial, and the upper bottom surface of the first truncated cone 442 and the upper bottom surface of the second truncated cone 443 are symmetrically disposed at both ends of the first wire portion 441.

[0078] It can be understood that a truncated cone refers to the portion between the bottom surface and the cross section after a cone is cut with a plane parallel to the bottom surface of the cone. The truncated cone includes an upper bottom surface and a lower bottom surface, and the radius of the upper bottom surface is smaller than the radius of the lower bottom surface. In the disclosed embodiment, the first truncated cone 442 is coaxial with the second truncated cone 443, and the upper bottom surface of the first truncated cone 442 and the upper bottom surface of the second truncated cone 443 are symmetrically arranged at both ends of the first wire portion 441, that is, the radius at the first wire portion 441 is smaller than the radius of any position on the first wire wheel 44, and the first wire portion 441 is the narrowest part of the first wire wheel 44. In this way, when the first traction line moves on the first wire wheel 44, it will naturally move along the side of the first truncated cone 442 or the second truncated cone 443 to the first wire portion 441 to ensure that the first traction line is always in contact with the first wire portion 441.
