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

[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, and the air inlet grille 30 is arranged in the installation space 21. The lifting module 40 is arranged on the face frame 20 and connected to the air inlet grille 30, and the lifting module 40 includes a winding gear 41 and a traction line. The winding gear 41 includes a gear portion 411 and a winding portion 412 connected to the gear portion 411, and the traction line is wound around the outer periphery of the winding portion 412 and connected to the air inlet grille 30. Among them, the rotation of the gear portion 411 can drive the winding portion 412 to rotate, so as to reel in or release the traction line, thereby driving the air inlet grille 30 to rise or fall relative to the face frame 20.

[0046] In the embedded air conditioner 10 provided by the embodiment of the present disclosure, the lifting module 40 is arranged on the face frame 20 and connected to the air inlet grille 30 through a traction line. The lifting module 40 includes a winding gear 41. The rotation of the gear portion 411 of the winding gear 41 can drive the winding portion 412 of the winding gear 41 to rotate, thereby driving the traction line wound on the outer periphery of the winding portion 412 to be wound or released, thereby driving the air inlet grille 30 connected to the traction line to rise or fall relative to the face frame 20, thereby realizing the automatic lifting function of the air inlet grille 30. Moreover, the cleaning difficulty of the embedded air conditioner 10 can be reduced, and the user can easily disassemble the air inlet grille 30 without the aid of a ladder and disassembly tools, thereby improving user satisfaction.

[0047] Optionally, combined Figures 4 to 8 As shown, the lifting module 40 also includes a guide wheel 42, which is configured to guide the traction line to move up and down along a preset path. The guide wheel 42 includes a first truncated cone 421, a second truncated cone 422, and a connecting portion 423 disposed between the first truncated cone 421 and the second truncated cone 422. The first truncated cone 421 and the second truncated cone 422 are coaxial, and the upper bottom surface of the first truncated cone 421 and the upper bottom surface of the second truncated cone 422 are symmetrically disposed at both ends of the connecting portion 423. Among them, the outer periphery of the connecting portion 423 is provided with a rough structure, and the traction line is wound around the rough structure.

[0048] The use of the wire wheel 42 to rotate the wire feeding can prevent the face frame 20 or the air inlet grille 30 from being cut during the movement of the traction wire.

[0049] 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 421 is coaxial with the second truncated cone 422, and the upper bottom surface of the first truncated cone 421 and the upper bottom surface of the second truncated cone 422 are symmetrically arranged at both ends of the connecting portion 423, that is, the radius at the connecting portion 423 is smaller than the radius of any position on the wire wheel 42, and the connecting portion 423 is the narrowest part of the wire wheel 42. In this way, when the traction line moves on the wire wheel 42, it will naturally move along the side of the first truncated cone 421 or the second truncated cone 422 to the connecting portion 423 to ensure that the traction line is always in contact with the connecting portion 423.

[0050] A rough structure is provided on the periphery of the connecting portion 423 to increase the friction between the traction line and the connecting portion 423 , so that when the traction line is wound or released by the winding portion 412 , the traction line moves to drive the wire wheel 42 to rotate.

[0051] Optionally, the rough structure is striae.

[0052] In this way, by providing leather grain on the outer peripheral surface of the connecting part 423, the friction between the connecting part 423 and the traction line is increased. The leather grain has a simple structure and does not need to be connected to other parts. The process difficulty is low and cost can be saved.

[0053] Optionally, the winding portion 412 includes a body 413 and a positioning portion 414, and the positioning portion 414 is disposed on the body 413. The positioning portion 414 and the connecting portion 423 are located on the same vertical plane, so that the traction line can be released from the positioning portion 414 to the connecting portion 423 or reeled from the connecting portion 423 to the positioning portion 414.

[0054] The positioning portion 414 and the connecting portion 423 are located in the same vertical plane, that is, the positioning portion 414 is arranged opposite to the connecting portion 423. In this way, when the traction line is wound around the winding portion 412, each circle of the traction line is repositioned by the positioning portion 414 to a position opposite to the connecting portion 423, so as to ensure that the traction line always corresponds to the connecting portion 423 during the movement, and the traction line can move according to a preset path.

[0055] Optionally, the body 413 includes a rotating shaft 4131 and a positioning fin 4132 disposed on the outer periphery of the rotating shaft 4131. The positioning portion 414 includes a cylindrical groove 4141, which is disposed on the positioning fin 4132 and a bottom surface of the cylindrical groove 4141 is connected to the positioning fin 4132. A notch 415 is provided on the side walls of the positioning fin 4132 and the cylindrical groove 4141, and the traction line is inserted into the cylindrical groove 4141 through the notch 415.

[0056] Combination Figure 7 and Figure 8 As shown, a plurality of fins are provided on the periphery of the rotating shaft 4131, and the plurality of fins are spaced around the periphery of the rotating shaft 4131. Compared with the traction line being directly wound around the rotating shaft 4131, the plurality of fins can increase the friction force required for the traction line to rotate relative to the rotating shaft 4131, thereby preventing the traction line from slipping.

[0057] Any one of the plurality of fins is connected to the positioning portion 414, and the fin connected to the positioning portion 414 is defined as a positioning fin 4132. Compared with the positioning portion 414 being directly fixed to the rotating shaft 4131, the positioning portion 414 being fixed to the positioning fin 4132 can reduce the connection difficulty and increase the connection strength, and the connection between the fixing portion and the positioning fin 4132 is relatively firm, and the structural stability is better.

[0058] The bottom surface of the cylindrical groove 4141 is connected to the positioning fin 4132, which can increase the contact area between the cylindrical groove 4141 and the positioning fin 4132, thereby improving the connection firmness between the cylindrical groove 4141 and the positioning fin 4132. Notches 415 are provided on the side walls of the positioning fin 4132 and the cylindrical groove 4141, and the traction wire is inserted into the cylindrical groove 4141 through the notch 415, so that the traction wire is confined to the positioning portion 414.

[0059] Optionally, the size of the notch 415 is equal to the diameter of the traction line, and the cylindrical groove 4141 is designed to be elastic.

[0060] In this way, the size of the notch 415 is equal to the diameter of the traction line, which can not only meet the purpose of inserting the traction line into the cylindrical groove 4141 through the notch 415 , but also reduce the risk of the traction line escaping from the notch 415 .

[0061] Optionally, the size of the notch 415 is larger than the diameter of the pulling wire.

[0062] For example, the size of the notch 415 is 1.1 times or 1.2 times the diameter of the traction line. In this way, the notch 415 is slightly larger than the diameter of the traction line, which facilitates the traction line to be reinserted into the cylindrical groove 4141 through the notch 415 during the winding process.

[0063] Optionally, the notch 415 includes a first notch 4151, and the first notch 4151 is disposed in the cylindrical groove 4141. The cylindrical groove 4141 also includes a first guiding slope 4142 and a second guiding slope 4143. The first guiding slope 4142 is disposed on the side wall of the cylindrical groove 4141 and is located on one side of the first notch 4151. The second guiding slope 4143 is disposed on the side wall of the cylindrical groove 4141 and is located on the other side of the first notch 4151. The first guiding slope 4142 and the second guiding slope 4143 are symmetrically disposed, and both the first guiding slope 4142 and the second guiding slope 4143 are used to guide the traction line to be inserted into the cylindrical groove 4141 through the first notch 4151.

[0064] In this way, the traction wire is smoothly inserted into the cylindrical groove 4141 by guiding the first guiding inclined surface 4142 and the second guiding inclined surface 4143 arranged at the first notch 4151 .

[0065] Optionally, the cylindrical groove 4141 includes a first bottom surface and a second bottom surface, the first bottom surface is connected to the positioning fin 4132, and the first guiding inclined surface 4142 and the second guiding inclined surface 4143 are both arranged close to the second bottom surface.

[0066] The first bottom surface of the cylindrical groove 4141 is connected to the positioning fin 4132, and the second bottom surface is opposite to the connecting portion 423 of the wire wheel 42. When the air inlet grille 30 rises, the traction line moves from the wire wheel 42 toward the winding portion 412. After passing through the connecting portion 423, the traction line first passes through the position where the second bottom surface is located. Therefore, the first guide slope 4142 and the second guide slope 4143 are both arranged at a position close to the second bottom surface to facilitate guiding the winding of the traction line.

[0067] Optionally, along the direction in which the traction line is inserted into the cylindrical groove 4141 , the first guide slope 4142 and the second guide slope 4143 are both inclined toward the middle of the cylindrical groove 4141 .

[0068] In this way, during the process of inserting the traction wire into the cylindrical groove 4141 , both the first guiding inclined surface 4142 and the second guiding inclined surface 4143 can guide the traction wire to be smoothly inserted into the cylindrical groove 4141 .

[0069] Optionally, the notch 415 includes a second notch 4152, and the second notch 4152 is provided at the positioning fin 4132. The positioning fin 4132 also includes a third guiding slope 4133 and a fourth guiding slope 4134. The third guiding slope 4133 is provided at one side of the second notch 4152. The fourth guiding slope 4134 is provided at the other side of the second notch 4152, and the fourth guiding slope 4134 is symmetrically arranged with the third guiding slope 4133. The third guiding slope 4133 and the fourth guiding slope 4134 are both used to guide the traction line to be inserted into the second notch 4152.

[0070] In this way, the traction wire is smoothly inserted into the positioning fin 4132 by guiding the third guiding slope 4133 and the fourth guiding slope 4134 arranged at the second notch 4152 .

[0071] Optionally, along the direction in which the traction line is inserted into the second notch 4152 , the third guiding slope 4133 and the fourth guiding slope 4134 are both inclined toward the middle of the second notch 4152 .

[0072] In this way, during the process of inserting the traction wire into the second notch 4152 , both the third guiding slope 4133 and the fourth guiding slope 4134 can guide the traction wire to be smoothly inserted into the positioning fin 4132 .

[0073] Optionally, the wire winding portion 412 further includes a fixing structure, and the fixing structure is used to fix one end of the traction wire.

[0074] In this way, one end of the traction line is connected to the fixed structure, and the other end of the traction line is connected to the air inlet grille 30 .

[0075] Optionally, combined Figures 1 to 9 As shown, the lifting module 40 further includes a housing 43, and a plug-in slot 431 is provided at the bottom of the housing 43. The embedded air conditioner 10 further includes a guide 50, which is provided at the air inlet grille 30 and connected to the traction line. The guide 50 includes a plug-in portion 51, wherein the plug-in portion 51 corresponds to the plug-in slot 431, so as to guide the air inlet grille 30 to be connected to the lifting module 40.

[0076] In this way, the guide member 50 is arranged on the air inlet grille 30, and the connection between the traction line and the guide member 50 is realized. The lifting module 40 also includes a housing 43, and the winding gear 41 and the guide wheel 42 are both arranged in the housing 43. The bottom of the housing 43 is provided with a plug-in slot 431, and the guide member 50 is provided with a plug-in portion 51. Through the cooperation between the plug-in portion 51 and the plug-in slot 431, during the rising process of the air inlet grille 30, the air inlet grille 30 is guided to be connected to the face frame 20 according to a preset path to prevent misalignment.

[0077] Optionally, the plug-in slot 431 includes a first flared portion 4311, which includes a first large end 4312 and a first small end 4313 arranged in sequence from bottom to top; and / or, the plug-in portion 51 includes a second flared portion 511, which includes a second large end 5111 and a second small end 5112 arranged in sequence from bottom to top, so as to guide the plug-in portion 51 to be inserted into the plug-in slot 431.

[0078] In this way, the plug slot 431 and / or the plug part 51 are in a trumpet shape, the first large end 4312 and the second large end 5111 are the openings of the trumpet, the first large end 4312 is located below the first small end 4313, and the second large end 5111 is located below the second small end 5112. When the plug slot 431 includes the first flared portion 4311 and the plug part 51 does not include the second flared portion 511, when the air inlet grille 30 rises, the first large end 4312 guides the plug part 51 to be inserted into the plug slot 431, so as to guide the guide 50 to be connected to the housing 43, thereby guiding the air inlet grille 30 to be connected to the face frame 20. When the plug-in portion 51 includes the second flared portion 511 and the plug-in slot 431 does not include the first flared portion 4311, when the air inlet grille 30 rises, the second small end 5112 is convenient to dock with the plug-in slot 431, and the second large end 5111 abuts against the opening of the plug-in slot 431 to limit the guide member 50 from continuing to move upward. When the plug-in slot 431 includes the first flared portion 4311 and the plug-in portion 51 includes the second flared portion 511, when the air inlet grille 30 rises, the first large end 4312 docks with the first small end 4313, the first large end 4312 guides the plug-in portion 51 to be inserted upward into the plug-in slot 431, and the second large end 5111 abuts against the first large end 4312 to limit the relative position between the guide member 50 and the housing 43, thereby limiting the relative position between the air inlet grille 30 and the face frame 20.

[0079] Optionally, the guide 50 is a hollow structure.

[0080] In this way, the hollow guide member 50 can reduce weight, lower the requirements on the load-bearing capacity of the traction line, and save costs.

[0081] Optionally, the guide member 50 further includes a fixed foot 52 , which is connected to the bottom end of the plug-in portion 51 , and the fixed foot 52 is provided with a wire groove 521 , in which the other end of the traction wire is disposed.

[0082] In this way, the other end of the traction wire is fixed to the guide member 50 through the wire groove 521 on the fixing foot 52 , thereby realizing the connection between the traction wire and the air inlet grille 30 .

[0083] Optionally, an opening is provided along the length direction of the plug-in portion 51 , the opening being opposite to the wire groove 521 , and the traction wire passes through the wire groove 521 , bends upward, and extends into the plug-in portion 51 through the opening.

[0084] In this way, the opening on the plug-in portion 51 facilitates the pulling wire to pass through the wire groove 521 and then be knotted and fixed, thereby providing operating space for the operator.

[0085] Optionally, the traction line is a steel wire rope.

[0086] The steel wire rope has good rigidity, high strength and is relatively strong. Using the steel wire rope on the traction line can improve the structural strength of the traction line and increase the load-bearing capacity of the traction line.

[0087] Optionally, the lifting module 40 further includes a screw 44 and a motor 45. The screw 44 is meshed with the gear portion 411. The motor 45 is connected to the screw 44, and the motor 45 is used to drive the screw 44 to rotate and then drive the winding gear 41 to rotate, so as to reel in or release the traction line, thereby driving the air inlet grille 30 to rise or fall relative to the face frame 20.

[0088] In this way, the screw 44 plus gear transmission is used to reduce the speed of the motor 45, and screws 44 and gears of different moduli can be used to achieve a controllable lifting speed. The screw 44 gear transmission can decompose the force applied by the air inlet grille 30 into the axial force of the motor 45 shaft and the tangential force of the shaft, thereby preventing the motor 45 from being damaged due to continuous force on the motor shaft, thereby causing the air inlet grille 30 to fall, and protecting the motor 45.

[0089] Optionally, the wire winding portion 412 and the gear portion 411 are coaxially arranged.

[0090] In this way, when the motor 45 drives the screw rod 44 to rotate and drives the gear part 411 to rotate, the wire winding part 412 coaxial with the gear part 411 can also rotate accordingly. The rotation of the wire winding part 412 can be achieved without adding other components. The structure is simple and the control is convenient.

[0091] Optionally, the wire winding portion 412 and the gear portion 411 are integrally formed.

[0092] In this way, the integrally formed winding portion 412 and gear portion 411 can reduce the difficulty of assembly and improve the assembly efficiency during the assembly process.

[0093] Optionally, the number of the lifting modules 40 is one or more.

[0094] When the number of the lifting module 40 is one, the number of the guide member 50 is also one, and one guide member 50 is disposed at the middle of the air inlet grille 30, and the lifting module 40 is connected to the middle of the air inlet grille 30. In this way, the structure is simpler and the cost is saved.

[0095] When there are two lifting modules 40, the two lifting modules 40 are relatively arranged on both sides of the face frame 20 (they can be both sides in the length direction or both sides in the width direction). There are two guide members 50, which are relatively arranged on both sides of the air inlet grille 30 and correspond to the two lifting modules 40 one by one. In this way, the air inlet grille 30 is prevented from rotating during the lifting process, and the stability of the connection between the air inlet grille 30 and the lifting module 40 is improved.

[0096] Optionally, the number of the lifting modules 40 is four, and the four lifting modules 40 are respectively arranged at four end corners of the face frame 20 .

[0097] There are four lifting modules 40, and at this time, there are also four guide members 50, which are respectively arranged at the four end corners of the air inlet grille 30 and correspond one to one with the four lifting modules 40. In this way, the lifting process of the air inlet grille 30 is more stable.

[0098] It is understandable that the number of the lifting modules 40 may be three, five, six, etc., as long as the center of gravity of the air inlet grille 30 is stable.
