[0048] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0049] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0050] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.
[0051] like Figures 1-4 As shown, the air conditioner 100 may include: an air conditioner body 1, a switch door 2, and a drive assembly 3. The switch door 2 is slidably engaged with the air conditioner body 1, and the switch door 2 is in a raised position relative to the air conditioner body 1 (e.g., ...). Figure 2 (as shown) and landing location (e.g.) Figure 1 It can slide up and down between (as shown).
[0052] The drive assembly 3 includes a support 30, a cable reel 31, a movable pulley 32, and a rope 33. The support 30 is located on the air conditioner body 1. There are two supports 30, which are respectively located on the lateral sides of the switch door 2. The movable pulley 32 is located on the switch door 2 and includes at least one first movable pulley 321. The first movable pulley 321 is located below the two supports 30. The rope 33 is wound around the movable pulley 32 and is wound around the first movable pulley 321 via the bottom of the first movable pulley 321. The two ends of the rope 33 extend and are connected to the two supports 30, and at least one end is connected to the cable reel 31. The cable reel 31 winds up the rope 33 to raise the switch door 2 and releases the rope 33 to lower the switch door 2.
[0053] It should be noted that the relative positions of the reel 31 and the support 30 are not limited. Once the relative positions of the reel 31 and the support 30 are determined, the matching relationship between the two ends of the rope 33 and the two supports 30 can be designed. For example, there are at least the following five embodiments.
[0054] Example 1
[0055] Each support 30 is equipped with a cable reel 31, and the two cable reels 31 are respectively connected to the two ends of the rope 33. Thus, the structure is simple and compact.
[0056] Example 2
[0057] One end of the rope 33 is fixedly connected to a support 30, and a reel 31 is mounted on the other support 30 and connected to the other end of the rope 33. As a result, the cost is low and the structure is simple and compact.
[0058] Example 3
[0059] One end of the rope 33 is fixedly connected to a support 30, and another support 30 is provided with a support pulley. A single cable reel 31 is spaced apart from the support 30. The other end of the rope 33 passes over the support pulley and is connected to the cable reel 31. This allows for flexible design of the cable reel 31's position; for example, it can be placed on a bracket directly opposite the door 2, thus reducing costs. Furthermore, in this embodiment, the cable reel 31 can be installed on the air conditioner body 1 or the door 2.
[0060] Example 4
[0061] Each support 30 is equipped with a support pulley, and there is one cord reel 31 spaced apart from both supports 30. Both ends of the rope 33 pass over the support pulleys on both sides and are connected to the same cord reel 31. This allows for flexible design of the cord reel 31's position; for example, it can be placed on a bracket directly opposite the door 2, improving the uniformity of the design at both ends, enhancing balance, and reducing costs. Furthermore, in this embodiment, the cord reel 31 can be installed on the air conditioner body 1 or the door 2.
[0062] Example 5
[0063] Each support 30 is equipped with a support pulley, and there are two cord reels 31 spaced apart from each of the two supports 30. The two ends of the rope 33 pass over the support pulleys on both sides and are connected to the two cord reels 31 respectively. This allows for flexible design of the cord reel 31's position; for example, the cord reel 31 can be placed on a bracket directly opposite the door 2, improving the uniformity of the design at both ends and enhancing balance. Furthermore, in this embodiment, the cord reel 31 can be placed on the air conditioner body 1 or the door 2.
[0064] Specifically, the rope 33 passes around each movable pulley 32 in sequence according to the designed path. When it passes around the first movable pulley 321, it passes through the bottom of the first movable pulley 321, so the rope 33 can apply an upward lifting force to the first movable pulley 321. In this way, the first movable pulley 321 can be used as the force point to support the opening and closing door 2. When the rope 33 lifts the first movable pulley 321, the first movable pulley 321 can pull the opening and closing door 2 to rise.
[0065] Specifically, when the reel 31 winds up the rope 33, the exposed length of the rope 33 shortens, allowing it to overcome the weight of the door 2 and pull it up. When the reel 31 releases the rope 33, the exposed length of the rope 33 lengthens, making it insufficient to overcome the weight of the door 2, causing it to descend under its own weight. For example, when the reel 31 rotates clockwise, the rope 33 is wound onto the reel 31, shortening its exposed length. When the reel 31 rotates counterclockwise, the rope 33 is released from the reel 31, lengthening its exposed length.
[0066] To simplify the description, the following text will only use the example of installing a reel 31 on each support 30.
[0067] For example, when both reels 31 are rotating clockwise, the exposed length of the rope 33 can be shortened more quickly; the exposed length of the rope 33 can also be shortened when one reel 31 is rotating clockwise and the other is not; the exposed length of the rope 33 can also be shortened when one reel 31 is rotating clockwise and the other is rotating counterclockwise, but the clockwise rotation speed is greater than the counterclockwise rotation speed. Therefore, in all these cases, the door 2 can be pulled up by the rope 33.
[0068] Conversely, when both reels 31 rotate in reverse, the exposed length of the rope 33 can be increased more quickly; the exposed length of the rope 33 can also be increased when one reel 31 rotates in reverse and the other does not rotate; the exposed length of the rope 33 can also be increased when one reel 31 rotates in reverse and the other rotates forward, but the speed of the reverse rotation is greater than the speed of the forward rotation. Therefore, in all these cases, the door 2 can descend under the influence of gravity.
[0069] Therefore, by setting supports 30 at both ends of the rope 33, and at least one support 30 including a winding reel 31, the sliding of the opening and closing door 2 can be cleverly driven. When both supports 30 include winding reels 31 and the two winding reels 31 work in the same direction, the sliding speed of the opening and closing door 2 can be accelerated, and the stress on each winding reel 31 can be reduced, thus increasing the service life of the winding reel 31. When one winding reel 31 fails or is damaged, the other winding reel 31 can work alone to drive the sliding of the opening and closing door 2, making the overall drive assembly 3 more reliable. In addition, the drive assembly 3 has a simple structure and low cost. Moreover, compared with the scheme of using a gear and rack assembly to drive the sliding of the opening and closing door 2, it can reduce drive noise, avoid frictional wear between the gear and rack during drive, and has higher mechanical efficiency.
[0070] In addition, since the two supports 30 are located on the lateral sides of the switch door 2 respectively, that is, the two supports 30 are distributed on both sides of the switch door 2 along the sliding direction perpendicular to the switch door 2, the force on the switch door 2 is more balanced. By setting the first movable pulley 321 lower than the two supports 30, when at least one cable reel 31 is working, the rope 33 can lift the switch door 2 by pulling the first movable pulley 321. With the cooperation of each movable pulley 32 and the rope 33, the rope 33 can self-adjust between the supports 30 on both sides, further improving the force balance of the switch door 2 and further improving the smoothness of the lifting and lowering of the switch door 2.
[0071] In some specific examples, the two reels 31 simultaneously wind up the rope 33, causing the exposed length of the rope 33 to shorten rapidly. This allows the door 2 to rise quickly against gravity, reaching the raised position. Simultaneously, the two reels 31 release the rope 33, causing the exposed length to lengthen rapidly. This allows the door 2 to descend quickly under gravity, reaching the lowered position. Furthermore, the synchronized rotation of the two reels 31 ensures a more balanced force on the door 2, further improving the smoothness of its raising and lowering.
[0072] Furthermore, when the two reels 31 work in the same direction, even if there is some inconsistency in the timing, they will not interfere with each other and affect the overall movement of the door 2. Even if the two reels 31 work in opposite directions, as long as there is a difference in their speed, the door 2 can still achieve lifting and lowering. There will be no problem of damage or failure of the drive component 3 due to the inconsistent rotation of the two reels 31, or the door 2 being unable to lift or lower. This can further improve the working reliability and service life of the drive component 3.
[0073] It should be noted that the specific type of air conditioner 100 is not limited; it can be a split-type air conditioner or an integrated air conditioner. A split-type air conditioner can be an indoor floor-standing unit or an indoor wall-mounted unit, etc., while an integrated air conditioner can be a window-type air conditioner or a portable air conditioner, etc. Once the specific type of air conditioner 100 is determined, those skilled in the art will understand the specific composition of the air conditioner body 1. For example, the air conditioner body 1 typically includes a casing and a fan and heat exchanger housed within the casing. When the air conditioner 100 is an indoor floor-standing unit, the casing may include a rear panel, a front panel 12, a base, and a top panel, etc. Furthermore, when the air conditioner 100 has functions other than temperature regulation, the air conditioner body 1 may also include auxiliary functional components, such as humidification components, fresh air components, purification components, etc., which will not be elaborated upon here.
[0074] Furthermore, it should be noted that the function of the switch door 2 is not limited. For example, in some embodiments, the switch door 2 can be used to cover the open area of the air conditioner body 1. The open area can be used to store accessories. For example, the air conditioner body 1 may have a storage cavity 11, which may contain a mobile sub-unit. The switch door 2 is used to open and close the storage cavity 11. When the switch door 2 opens the storage cavity 11, the mobile sub-unit can be taken out of the storage cavity 11. After the mobile sub-unit is taken out of the storage cavity 11, or when the mobile sub-unit is stored back into the storage cavity 11, the switch door 2 can be used to close the storage cavity 11. For example, in other embodiments, the air conditioner body 1 may have vents, such as air outlets and air inlets. The switch door 2 can also be used to open and close the vents of the air conditioner body 1. In this way, when the vents are not needed, the switch door 2 can be used to cover and close the vents to prevent dust and other particles from entering the vents. When the vents are needed, the switch door 2 can be used to open the vents to ensure normal ventilation.
[0075] Some air conditioners in related technologies are equipped with liftable doors, which are driven by a rack and pinion mechanism. However, achieving door lifting and lowering using a rack and pinion mechanism is relatively expensive and structurally complex. Furthermore, rack and pinion drive systems experience significant friction, resulting in substantial energy loss, low mechanical efficiency, and high operating noise. Additionally, if the rack and pinion drive system uses a single motor (one gear driving one rack), the force on the door becomes unbalanced, potentially causing skewness. If the system uses two motors (two gears driving one rack from both sides of the width), inconsistencies in the movement of the two motors can cause interference, affecting the normal lifting and lowering of the door and potentially damaging or shortening the lifespan of the motors.
[0076] In the air conditioner 100 of this embodiment, the lifting and lowering of the switch door 2 is driven by a rope 33. Two reels 31 connect the two ends of the rope 33, or one reel 31 connects to and a support 30 to fix the two ends of the rope 33. When the reel 31 is working, it can wind up the rope 33, lifting the switch door 2 upwards. When the reel 31 reverses, it releases the rope 33, and the switch door 2 descends under gravity. When the air conditioner 100 is equipped with a storage cavity 11, the lifting and lowering of the switch door 2 can switch the storage cavity 11, satisfying the requirement for the mobile unit to enter and exit the storage cavity 11.
[0077] Therefore, compared with the gear and rack mechanism, the drive component 3 has almost no mechanical friction during operation, very little energy loss, more efficient movement and lower noise; through the cooperation of the rope 33 and each moving pulley 32, the rope 33 can automatically adjust its position between the supports 30 on both sides to adapt to the inconsistency of the movement at both ends of the rope 33, thereby balancing the force on the opening and closing door 2, improving the smoothness of the opening and closing door 2, and preventing damage or shortening of the life of the reel 31.
[0078] In short, the drive assembly 3 according to the embodiments of the present invention can solve the problems of high motion noise, low mechanical efficiency, unbalanced force when using a single motor to drive the gear and rack mechanism, and asynchronous motion when using two motors to drive the gear and rack mechanism. Moreover, compared with gear and rack transmission, the drive assembly 3 of the embodiments of the present invention has a simpler structure, higher working reliability, and smoother movement of the door 2.
[0079] In some embodiments, such as Figure 4 As shown, when the door 2 is in the lowered position, two supports 30 are symmetrically arranged on both sides of the upper end of the door 2. This maximizes the upward distance of the door 2.
[0080] In some embodiments, such as Figure 4 As shown, the first movable pulley 321 is located at the lower end of the opening and closing door 2. This maximizes the upward distance of the opening and closing door 2.
[0081] In some embodiments, such as Figure 4 and Figure 5 As shown, there are multiple first movable pulleys 321 spaced laterally. Each movable pulley 321 also includes a second movable pulley 322, which is located on the door 2. At least one second movable pulley 322 is positioned above each pair of adjacent first movable pulleys 321. Therefore, by providing multiple first movable pulleys 321, more force-bearing points are provided, resulting in a more stable and reliable drive for the door 2 to rise and fall. Furthermore, by providing the second movable pulleys 322, the direction of the rope 33 can be changed, providing tension and allowing the rope 33 to be more stably wound around the multiple second movable pulleys 322, improving the reliability and stability of the drive.
[0082] For example, in a specific example, there can be multiple movable pulleys 32, including two first movable pulleys 321 and one second movable pulley 322. The two first movable pulleys 321 are located at the lower end of the door 2 and are spaced apart laterally. The second movable pulley 322 is located between the two first movable pulleys 321 and is higher than the two first movable pulleys 321. In this way, the rope 33 can extend from a winding reel 31, first pass downwards around a first movable pulley 321 that is close to it, then pass upwards around the second movable pulley 322, then pass downwards around another first movable pulley 321, then pass upwards around another first movable pulley 321, and then be wound around another winding reel 31.
[0083] Therefore, when the rope 33 is wound and shortened by the reel 31, the door 2 can be lifted by raising the two first movable pulleys 321. Since the two first movable pulleys 321 are spaced laterally, the force on the door 2 is more balanced, improving the smoothness of its lifting and lowering. Furthermore, by setting a second movable pulley 322 located between and higher than the two first movable pulleys 321, the rope 33 can be wound into the second movable pulley 322 from top to bottom and out from bottom to top. This makes the cooperation between the rope 33 and the second movable pulley 322 more reliable, improving the problem of the rope 33 detaching from the second movable pulley 322, and thus increasing the reliability of the rope 33 lifting the door 2 through the second movable pulley 322. In addition, since the two first movable pulleys 321 are located at the lower end of the door 2, the lifting height of the first movable pulleys 321 can be maximized. In short, the rope 33 in this embodiment has a simple winding method, requires fewer pulleys 32, has a lower cost, and can better distribute the force, making the force on the opening and closing door 2 more balanced and the movement more reliable and stable.
[0084] Optionally, the extension direction of the rotation axis of the first movable pulley 321 is perpendicular to the extension direction of the rotation axis of the second movable pulley 322. For example, in Figure 5 In the example shown, the axis of rotation of the first movable pulley 321 extends in the left-right direction, and the axis of rotation of the second movable pulley 322 extends in the front-back direction. In this way, when winding the rope, the rope 33 can be wound approximately symmetrically about the second movable pulley 322, thereby simplifying the winding process. Furthermore, the two winding devices 31 can be installed symmetrically, reducing the difficulty of design and assembly.
[0085] In some embodiments of the present invention, such as Figure 5 and Figure 6As shown, the air conditioner 100 includes: a first pulley bracket 4, which is disposed on the switch door 2 and includes a first line-blocking portion 41; a first movable pulley 321 is mounted on the first pulley bracket 4, and the first line-blocking portion 41 covers the bottom periphery and both axial sides of the first movable pulley 321. Therefore, by providing the first pulley bracket 4, the first movable pulley 321 can be installed, and by providing the first line-blocking portion 41, the rope 33 can be better prevented from detaching from the first movable pulley 321, thereby improving the operational reliability of the drive assembly 3.
[0086] For example, in Figure 5 and Figure 6 In the specific example shown, the first wire-blocking portion 41 may include a first peripheral portion 411 and two first end portions 412. The two first end portions 412 are located on both axial sides of the first movable pulley 321. The first peripheral portion 411 is located at the bottom of the peripheral side of the first movable pulley 321 and is connected to the two first end portions 412 respectively. The first movable pulley 321 is located in the first mounting cavity defined by the first peripheral portion 411 and the two first end portions 412. A first winding space 42 is defined between the first peripheral portion 411 and the peripheral surface of the first movable pulley 321. The two circumferential ends of the first peripheral portion 411 and the first movable pulley 321 respectively define an upwardly open first wire passage. Thus, the rope 33 can extend downward into the first winding space 42 through the first wire passage on one side, wind along the first movable pulley 321 to the first wire passage on the other side, and then extend upward into the first winding space 42. Therefore, by limiting the opening orientation of the first cable passage, the rope 33 can be better prevented from detaching from the first movable pulley 321, thereby improving the working reliability of the drive assembly 3.
[0087] In some embodiments of the present invention, such as Figure 5 and Figure 7 As shown, the air conditioner 100 includes: a second pulley bracket 5, which is disposed on the switch door 2 and includes a second guide wire portion 51; a second movable pulley 322 is mounted on the second pulley bracket 5, and the second guide wire portion 51 covers the top periphery and both axial sides of the second movable pulley 322. Therefore, by providing the second pulley bracket 5, the second movable pulley 322 can be installed, and by providing the second guide wire portion 51, the rope 33 can be better prevented from detaching from the second movable pulley 322, thereby improving the operational reliability of the drive assembly 3.
[0088] For example, in Figure 5 and Figure 7In the specific example shown, the second wire stop portion 51 may include a second peripheral portion 511 and two second end portions 512. The two second end portions 512 are located on both axial sides of the second movable pulley 322. The second peripheral portion 511 is located on the top of the peripheral side of the second movable pulley 322 and is connected to the two second end portions 512 respectively. The second movable pulley 322 is located in the second mounting cavity defined by the second peripheral portion 511 and the two second end portions 512. A second winding space 52 is defined between the second peripheral portion 511 and the peripheral surface of the second movable pulley 322. The two circumferential ends of the second peripheral portion 511 and the second movable pulley 322 respectively define downward-opening second wire passages. Thus, the rope 33 can extend upward into the second winding space 52 through the second wire passage on one side, wind along the second movable pulley 322 to the second wire passage on the other side, and then extend downward out of the second winding space 52. Therefore, by limiting the opening orientation of the second cable passage, the rope 33 can be better prevented from detaching from the second movable pulley 322, thereby improving the working reliability of the drive assembly 3.
[0089] It should be noted that the specific structure of the switch door 2 is not limited. For example, in some embodiments, the switch door 2 can be a single panel, while in other embodiments, it can be a multi-layer panel. For instance, a multi-layer panel may include an outer panel and an inner panel stacked along its thickness direction. The outer panel serves as the exterior surface, and the inner panel is located inside the outer panel and is used to install the first pulley bracket 4 and the second pulley bracket 5, thereby avoiding exposure of the connection structure. For example, screw holes can be provided on the inner panel, and the first pulley bracket 4 and the second pulley bracket 5 can be installed on the inner panel using screws corresponding to these holes. However, this is not the only possibility; the first pulley bracket 4 and the second pulley bracket 5 can also be installed by providing a snap-fit structure on the inside of the switch door 2, which will not be elaborated here. Furthermore, the connection method between the inner panel and the outer panel is not limited; for example, it can be achieved through adhesive bonding, snap-fit connection, or threaded connection, etc.
[0090] Of course, the present invention is not limited to this. In other embodiments of the present invention, a greater number of movable pulleys 32 can be selected. For example, three first movable pulleys 321 and two second movable pulleys 322 can be set. The two second movable pulleys 322 are at the same height, and the three first movable pulleys 321 are at the same height. A second movable pulley 322 is set above each pair of adjacent first movable pulleys 321. The rope 33 still passes around multiple movable pulleys 32 in sequence along the horizontal direction, etc., which will not be elaborated here.
[0091] Furthermore, the present invention is not limited to this. For example, in other embodiments of the present invention, the drive assembly 3 may not include the second movable pulley 322. For example, in some other embodiments, there are multiple first movable pulleys 321 spaced laterally, and the drive assembly 3 also includes a fixed pulley, which is disposed on the air conditioner body 1. At least one fixed pulley is provided above each pair of adjacent first movable pulleys 321 (this embodiment is not shown in the figure). Thus, during the process of opening and closing the door 2 relative to the air conditioner body 1, the fixed pulley is fixed relative to the air conditioner body 1, so the length of the rope 33 between the first movable pulley 321 and the fixed pulley changes, thereby further increasing the opening and closing speed of the door 2.
[0092] It should be noted that the specific configuration of the first movable pulley 321 is not limited; for example, it can be a roller or a rolling bearing, all of which facilitate the looping of the rope 33 and its free sliding relative to it. Similarly, the specific configuration of the second movable pulley 322 is not limited; for example, it can also be a roller or a rolling bearing, all of which facilitate the looping of the rope 33 and its free sliding relative to it.
[0093] Furthermore, it should be noted that the specific configuration of the cable reel 31 according to the embodiments of the present invention is not limited, and may include, for example, a drum 316 or a reel. To facilitate the connection between the rope 33 and the drum 316, a threading hole 3161 may be provided on the drum 316. For example, in Figure 8 and Figure 9 In the example shown, the cable reel 31 may include a drive motor 311, a motor upper cover 312, a motor lower cover 313, a vibration damping pad, an adapter block 315, and a reel 316. The drive motor 311 is installed within the mounting space defined by the motor upper cover 312 and the motor lower cover 313, with the motor shaft of the drive motor 311 extending outside the mounting space and connected to the reel 316 located outside the mounting space via the adapter block 315. The vibration damping pad is disposed within the mounting space and sandwiched between the drive motor 311 and the motor upper cover 312, and between the drive motor 311 and the motor lower cover 313, thereby achieving vibration reduction and noise reduction. The specific type of the vibration damping pad is not limited; for example, it can be a rubber pad 314. Similarly, the specific type of the drive motor 311 is not limited; for example, it can be a servo motor, etc., and no restriction is imposed here.
[0094] In some embodiments of the present invention, such as Figure 2 and Figure 5As shown, sliding components 6 are provided on both sides of the horizontal axis of the switch door 2, and slide rail components 7 are provided on both sides of the horizontal axis of the air conditioner body 1. The sliding components 6 slide in cooperation with the corresponding slide rail components 7. Thus, by providing slide rail components 7 and sliding components 6 on both sides of the horizontal axis of the switch door 2, the stability of the relative sliding between the switch door 2 and the air conditioner body 1 can be further improved. In addition, since the sliding components 6 and slide rail components 7 are not located in the middle of the switch door 2, the problem of partial obstruction caused by the slide rail components 7 remaining in the closed position of the switch door 2 when the switch door 2 is in the open position is avoided.
[0095] Optionally, the length direction of the door 2 is vertical, and the width direction is horizontal. In this case, the air conditioner body 1 is provided with slide rail assemblies 7 on both sides of the width of the door 2, and the sliding assembly 6 slides and cooperates with the slide rail assembly 7 on the corresponding side. Thus, by providing slide rail assemblies 7 and sliding assemblies 6 on both sides of the width of the door 2, the stability of the relative sliding between the door 2 and the air conditioner body 1 can be further improved.
[0096] Furthermore, combined Figures 10-13 As shown, each side of the slide rail assembly 7 includes a first slide rail 71 and a second slide rail 72 arranged vertically at intervals, as... Figure 5 As shown, each sliding assembly 6 includes a first sliding member 61 that cooperates with the first sliding rail 71 and a second sliding member 62 that cooperates with the second sliding rail 72. The lower ends of the first sliding rail 71 and the lower ends of the second sliding rail 72 both extend obliquely away from the opening and closing door 2. It should be noted that the oblique extension can be along a straight line or along a curve, such as an arc, and there is no limitation here.
[0097] That is, each sliding assembly 6 includes a first sliding member 61 and a second sliding member 62 spaced apart along the length of the door 2. The first sliding member 61 is slidably engaged with the first sliding rail 71, and the second sliding member 62 is slidably engaged with the second sliding rail 72. The end of the first sliding rail 71 near the second sliding rail 72 and the end of the second sliding rail 72 away from the first sliding rail 71 extend obliquely away from the door 2.
[0098] In other words, each side of the slide rail assembly 7 is divided into two sections: a first slide rail 71 and a second slide rail 72. This allows the end of the first slide rail 71 that is closer to the second slide rail 72 to extend at an angle away from the closing door 2, while the end of the second slide rail 72 that is farther from the first slide rail 71 can extend at an angle away from the first slide rail 71.
[0099] Therefore, when the door 2 moves along the direction from the second sliding rail 72 to the first sliding rail 71, it can first move a certain distance away from the air conditioner body 1 in the general thickness direction of the door 2 via the inclined end of the sliding rail, avoiding interference between the door 2 and the exterior surface of the air conditioner body 1, and then slide normally along the straight section of the sliding rail. Similarly, when the door 2 moves along the direction from the first sliding rail 71 to the second sliding rail 72, it can first slide normally along the straight section of the sliding rail, and when it is about to slide into place, it can move a certain distance closer to the air conditioner body 1 in the general thickness direction of the sliding rail via the inclined end of the sliding rail, so as to reduce the fitting gap between the door 2 and the air conditioner body 1, so that the exterior surface of the door 2 and the exterior surface of the air conditioner body 1 can be coplanar or as coplanar as possible, thereby improving the appearance consistency of the air conditioner 100.
[0100] For example, combining Figures 1-2 , Figures 10-13 In the specific example shown, the switch door 2 can slide up and down relative to the air conditioner body 1 between the raised position and the lowered position. The air conditioner body 1 includes a front panel 12 and a storage cavity 11. The storage cavity 11 is located below the front panel 12. When the switch door 2 is in the lowered position, the switch door 2 is located below the front panel 12 to cover the storage cavity 11. When the switch door 2 is raised to the raised position, at least a portion of the switch door 2 moves above the storage cavity 11 and is located in front of the front panel 12 to open the storage cavity 11.
[0101] The first sliding rail 71 is located on the left and right sides of the front panel 12, and the second sliding rail 72 is located on the left and right sides of the storage cavity 11. Specifically, the first sliding rail 71 is provided on the left and right sides of the front panel 12, and the second sliding rail 72 is provided on the left and right sides of the storage cavity 11. The first sliding rail 71 on the left is located above the second sliding rail 72 on the left, and the first sliding rail 71 on the right is located above the second sliding rail 72 on the right. Both the first sliding rail 71 and the second sliding rail 72 extend vertically. The lower end of each first sliding rail 71 extends backward at an angle from top to bottom, and the lower end of each second sliding rail 72 also extends backward at an angle from top to bottom.
[0102] When the storage cavity 11 needs to be opened, the door 2 moves upward from the lowered position to the raised position. Guided by the lower ends of the first sliding rail 71 and the second sliding rail 72, the door 2 can tilt forward and upward to move to the front side of the plane where the front surface of the front panel 12 is located. Then it moves upward in a straight line along the first sliding rail 71 and the second sliding rail 72, so that the door 2 can move in front of the front panel 12 without being interfered with by the front panel 12.
[0103] When the storage cavity 11 needs to be closed, the switch door 2 moves from the raised position to the lowered position. The switch door 2 first moves downward in a straight line along the first sliding rail 71 and the second sliding rail 72. When it is about to reach the lowered position, it is guided by the lower end of the first sliding rail 71 and the lower end of the second sliding rail 72, causing the switch door 2 to tilt backward and downward so that the front surface of the switch door 2 is coplanar or substantially coplanar with the front surface of the front panel 12, thereby improving the appearance consistency of the air conditioner 100.
[0104] For example, the upper and lower halves of the air conditioner body 1 are respectively designed with sliding rails on the left and right sides. The upper sliding rail is the first sliding rail 71, and the lower sliding rail is the second sliding rail 72. The first sliding rail 71 and the second sliding rail 72 have the same shape. The first sliding rail 71 on the left and right sides are symmetrically arranged, and the second sliding rail 72 on the left and right sides are symmetrically arranged. Each sliding rail extends vertically as a whole, with the lower end extending backward at an angle. Thus, when the door 2 moves along the first sliding rail 71 and the second sliding rail 72, the upward movement of the door 2 is first forward sliding and then upward sliding; the downward movement of the door 2 is first downward sliding and then backward sliding. This ensures the smooth raising and lowering of the door 2 and makes the overall appearance of the air conditioner 100 consistent when the door 2 is lowered.
[0105] Furthermore, it is worth noting that since the door 2 moves along its approximate thickness during operation, the rope 33 has a range of motion between the movable pulley 32 and the winding device 31. Therefore, by setting the aforementioned first pulley bracket 4 and second pulley bracket 5, the problem of the rope 33 detaching from the movable pulley 32 can be effectively prevented, improving the operational reliability of the drive assembly 3. In addition, it should be noted that the specific material of the rope 33 is not limited; for example, it can be made of steel wire rope, thus possessing good load-bearing capacity and a long service life.
[0106] In some embodiments, such as Figure 2 As shown, the second sliding rail 72 is located on the inner wall of the receiving cavity 11, and at least a portion of the second sliding member 62 extends into the receiving cavity 11 to slide and engage with the second sliding rail 72. Therefore, the receiving cavity 11 can be used to conceal the second sliding rail 72, thereby protecting the second sliding rail 72 and improving the reliability of the engagement between the second sliding rail 72 and the second sliding member 62. Additionally, as... Figure 2 As shown, the first sliding rail 71 is located on the left and right sides of the front panel 12, so it can be selected to be exposed to simplify the structure and facilitate processing.
[0107] It should be noted that the specific configuration of the first sliding member 61 and the second sliding member 62 is not limited, for example, in Figure 13 and Figure 14In the example shown, both the first sliding member 61 and the second sliding member 62 may include: a structural support 63, a roller bearing 64, and a bullseye bearing 65. The structural support 63 has a support shaft 66 with a blind hole in the middle. The roller bearing 64 is mounted on the support shaft 66, and the bullseye bearing 65 is installed in the blind hole. Both the first sliding rail 71 and the second sliding rail 72 are constructed as grooves. The groove includes two side walls and a bottom wall connecting the two side walls. A limiting groove 73 is formed on the bottom wall of the groove. The roller bearing 64 is located between the two side walls and rolls along the side walls. The bullseye bearing 65 slides in conjunction with the limiting groove 73. Thus, when the sliding rails and sliding members on both sides are in place, reliable engagement and limiting of the sliding members and sliding rails can be achieved, reducing sliding wear between them and improving the smoothness of sliding engagement. Furthermore, by setting the bullseye bearing 65, the problem of wear caused by contact between the end face of the roller bearing and the bottom wall of the groove can be avoided.
[0108] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the air conditioner 100 may also include a locking component 9, which is located between the door 2 and the air conditioner body 1 and can be switched between a locked state and an unlocked state. When the locking component 9 is switched to the locked state, the locking component 9 locks the relative position of the air conditioner body 1 and the door 2. The locking component 9 is adapted to switch to the locked state when the door 2 moves to the raised position and / or lowered position.
[0109] In other words, the locking component 9 can be configured to switch to the locked state only when the door 2 is in the raised position. Alternatively, the locking component 9 can be configured to switch to the locked state only when the door 2 is in the lowered position. Furthermore, the locking component 9 can be configured to switch to the locked state when the door 2 is in the raised position and also when the door 2 is in the lowered position. Therefore, the locking component 9 can be used to ensure that the door 2 remains relatively stably in either the raised or lowered position.
[0110] It should be noted that the locking component 9 can be either automatic or driven. Automatic locking means that, without control, when the door 2 moves relative to the air conditioner body 1 to the target position, the locking component 9 can automatically switch to the locked state. For example, when the door 2 moves relative to the air conditioner body 1 to the target position, the bolt 91 in the locking component 9 is aligned with the keyhole 92. At this time, the bolt 91 can automatically enter the keyhole 92 under the action of the spring force. When the door 2 moves relative to the air conditioner body 1, it can overcome the spring force, causing the bolt 91 to disengage from the keyhole 92 to unlock. In addition, the drive locking mode refers to the requirement that when the door 2 moves relative to the air conditioner body 1 to the target position, the locking assembly 9 can be controlled to switch to the locked state. For example, when the door 2 moves relative to the air conditioner body 1 to the target position, the bolt 91 in the locking assembly 9 is positioned opposite the lock hole 92. At this time, the bolt 91 can be controlled to drive into the lock hole 92. When the door 2 needs to move relative to the air conditioner body 1, the bolt 91 is controlled to drive out of the lock hole 92 again, thereby unlocking.
[0111] Furthermore, when the locking assembly 9 is a drive-locking type, the air conditioner 100 may also include a detection assembly 8 and a control assembly. The detection assembly 8 can be used to detect the position of the open / closed door 2. The control assembly is electrically connected to the locking assembly 9, the detection assembly 8, and the cord reel 31, and is used to control the locking assembly 9 and the cord reel 31. Thus, through the electrical control design, when the detection assembly 8 detects that the open / closed door 2 has reached the raised position, the control assembly controls the locking assembly 9 to switch to the locked state, and / or, when the detection assembly 8 detects that the open / closed door 2 has reached the lowered position, the control assembly controls the locking assembly 9 to switch to the locked state. Moreover, through the electrical control design, when it is necessary to raise or lower the open / closed door 2, the control assembly first controls the locking assembly 9 to switch to the unlocked state, and then controls the cord reel 31 to operate.
[0112] For example, in some alternative examples, the detection component 8 may include a magnet 81, an upper Hall switch 82, and a lower Hall switch 83. The upper Hall switch 82 and the lower Hall switch 83 are both mounted on the air conditioner body 1 and are located at the upper and lower ends of the receiving cavity 11, respectively. The magnet 81 is mounted on the switch door 2 and is located at the lower end of the switch door 2. The locking component 9 may include an actuator, a latch 91, and a lock hole 92. The actuator may include a push rod servo motor or a gear and rack mechanism, etc. The latch 91 is located on the air conditioner 100 and at the upper end of the receiving cavity 11. The lock hole 92 is located on the switch door 2, and the upper and lower ends of the switch door 2 are respectively provided with lock holes 92.
[0113] The distance between magnet 81 and a Hall switch determines whether the switch door 2 has moved to the target position. When the distance between magnet 81 and a Hall switch is less than or equal to a set value, the switch door 2 has moved to a target position, the cable reel 31 stops operating, and the actuator drives the latch 91 to pop out into the lock hole 92, locking the switch door 2. Upon receiving a start signal, the actuator drives the latch 91 to retract and move out of the lock hole 92, unlocking the switch door 2. The cable reel 31 reverses, allowing the switch door 2 to move in the other direction. When the distance between magnet 81 and another Hall switch is less than or equal to a set value, the switch door 2 has moved to another target position, the cable reel 31 stops operating, and the actuator drives the latch 91 to pop out into the lock hole 92, locking the switch door 2 again.
