Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a sliding door assembly and an air conditioner. Background Technology

[0002] Currently, many air conditioner indoor units have sliding doors at the air outlet that can block the air outlet. There are also drive devices at the top and bottom of the air conditioner indoor unit. The sliding racks in the drive devices are connected to the top and bottom of the sliding door respectively to drive the sliding door to rotate around the circumference of the air conditioner.

[0003] However, the sliding doors of existing air conditioner indoor units are generally fixed by screws and sliding racks of the drive unit, so that the sliding door can slide with the sliding rack of the drive unit. In order to ensure the sliding stability of the sliding door, at least two screws are required at the top and bottom of the sliding door to lock with the sliding rack, which makes disassembly inconvenient during subsequent maintenance.

[0004] In summary, overcoming the aforementioned defects in the sliding door limiting structure of existing air conditioning indoor units is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a sliding door assembly and an air conditioner to alleviate the technical problem of inconvenient disassembly during subsequent maintenance of the sliding door limiting structure in the indoor unit of an air conditioner in the prior art.

[0006] The sliding door assembly provided by the present invention includes a sliding door and a drive device.

[0007] The drive device includes a drive box and a drive mechanism. The drive box is used to be fixedly connected to the air conditioner frame, and the drive mechanism is installed in the drive box. The drive mechanism has a sliding rack.

[0008] The sliding door is provided with a lower limit member, which abuts against the upward-facing surface of the drive box, and the lower limit member can move along the drive box.

[0009] The sliding rack is provided with an upper limit stop, which engages with the upward-facing surface of the sliding door to restrict the upward degree of freedom of the sliding door; or, the sliding door is provided with an upper limit stop, which engages with the downward-facing surface of the sliding rack, and the downward-facing surface of the sliding rack can restrict the upward degree of freedom of the sliding door.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The sliding door assembly provided by this invention utilizes an upper limit stop on the sliding rack to engage with the upward-facing surface of the sliding door, or utilizes an upper limit stop on the sliding door to engage with the downward-facing surface of the sliding rack. In this way, the upward degree of freedom of the sliding door can be restricted. The upward degree of freedom of the sliding door is an important indicator of the stable operation of the sliding door. Therefore, the screws used to lock the sliding door and the sliding rack can be greatly reduced or even eliminated.

[0012] During subsequent maintenance, the upper limit component can be removed to release the upward degree of freedom of the sliding door. Therefore, the sliding door assembly provided by this invention is easy to disassemble, which can reduce the time and manpower spent on subsequent disassembly and has high disassembly efficiency.

[0013] Preferably, as one possible implementation, the sliding door is provided with a lower limit member, which abuts against the upward-facing surface of the drive box, and the lower limit member is movable along the drive box.

[0014] The advantage is that disassembly is easier.

[0015] Preferably, as one possible implementation, the upper limit member is a screw, the screw having a limiting section and a connecting section, the limiting section being located between the connecting section and the head of the screw, the connecting section being threadedly connected to the sliding rack, and the limiting section being used to engage with the upward-facing surface of the sliding door.

[0016] The advantage is that during subsequent maintenance, simply unscrewing the screws can remove the restriction on the upward freedom of the sliding door, making the operation very convenient.

[0017] Preferably, as one possible implementation, the screw is a stepped screw, the smooth section of the stepped screw is the limiting section, and the threaded section of the stepped screw is the connecting section.

[0018] The benefits include easier installation, reduced wear caused by the interaction force between the step screw and the sliding door, and improved reliability of the connection between the step screw and the sliding rack.

[0019] Preferably, as one possible implementation, there is a gap between the head of the screw and the sliding door.

[0020] The benefits are that the sliding door is less likely to scratch the inner air vent frame, and the requirements for screw assembly are reduced.

[0021] Preferably, as one possible implementation, the top end face of the sliding door is provided with a groove, which cooperates with the upper limit member.

[0022] The beneficial effect is that it makes it easier to ensure the reliability of the upper limit component in limiting the sliding door.

[0023] Preferably, as one possible implementation, the upper limit stop is one, and the upper limit stop is located at the middle position of the circumference of the sliding door.

[0024] The benefits include reducing the time and manpower spent on disassembly, and the fact that sliding doors are less prone to tilting due to unbalanced forces.

[0025] Preferably, as one possible implementation, the lower limiting member is a rolling member, which rolls in cooperation with the upward-facing surface of the drive box.

[0026] The beneficial effects are that it can reduce the sliding resistance of the sliding door, improve the driving efficiency, and also reduce the wear on the drive box and the lower limit component, thus extending their service life.

[0027] Preferably, as one possible implementation, there are at least two lower limit members, and the lower limit members are arranged at intervals along the sliding direction of the sliding door.

[0028] The beneficial effect is that it makes it easier to improve the support effect of the lower limit component on the sliding door, making the sliding door more balanced in terms of force, so that the sliding door is less likely to tilt, thus ensuring the smoothness of the sliding door's movement.

[0029] Preferably, as one possible implementation, the rolling element is a bearing.

[0030] The beneficial effect is that it can greatly reduce the friction between the lower limit component and the drive box, making the sliding door slide more smoothly.

[0031] Preferably, as one possible implementation, the sliding door is provided with a first limiting part, and the sliding rack is provided with a second limiting part. The first limiting part cooperates with the second limiting part, and the second limiting part is used to limit the horizontal displacement of the sliding door relative to the sliding rack.

[0032] The beneficial effect is that it can limit the horizontal offset of the sliding door relative to the sliding rack.

[0033] Preferably, as one possible implementation, the sliding door has a locking hole, the extension direction of the locking hole is at an angle to the horizontal direction, the first limiting part includes the hole wall of the locking hole; the sliding rack is provided with a protrusion, the protrusion can be inserted into the locking hole, and the second limiting part includes the part of the protrusion that cooperates with the hole wall of the locking hole.

[0034] The beneficial effect is that the protrusion can limit the horizontal displacement of the sliding door relative to the sliding rack, that is, the sliding door can slide synchronously with the sliding rack. During subsequent maintenance, the sliding door can be lifted along the extension direction of the locking hole, and the protrusion can be easily disengaged from the locking hole without any other disassembly steps, thus ensuring the ease of disassembly.

[0035] Preferably, as one possible implementation, the driving mechanism includes a power source, a gear, and a rack. The power source is installed in the driving box and is connected to the gear for driving the gear to rotate. The gear meshes with the rack, and the sliding rack includes the rack.

[0036] The beneficial effect is that it enables the sliding door to be driven, and the upper limit component can transfer the load of the rack to the sliding door, thereby reducing the load on the rack and allowing it to only play a driving role, thus improving the smoothness of the sliding door's operation.

[0037] The present invention also provides an air conditioner that includes the above-described sliding door assembly.

[0038] The air conditioner provided by the present invention has all the advantages of the above-mentioned sliding door assembly because it has the above-mentioned sliding door assembly. It is easy to disassemble, which can reduce the time and manpower spent on subsequent disassembly and has high disassembly efficiency. Attached Figure Description

[0052] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0054] See Figures 1-3 This embodiment provides a sliding door assembly, which includes a sliding door 100 and a drive device 200; the drive device 200 includes a drive box 210 and a drive mechanism, the drive box 210 is used to be fixedly connected to an air conditioner frame, the drive mechanism is installed in the drive box 210, and the drive mechanism has a sliding rack 220.

[0055] An upper limit stop is provided on the sliding rack 220, which cooperates with the upward-facing surface of the sliding door 100 to limit the upward degree of freedom of the sliding door 100; or, an upper limit stop is provided on the sliding door 100, which cooperates with the downward-facing surface of the sliding rack 220, and the downward-facing surface of the sliding rack 220 can limit the upward degree of freedom of the sliding door 100.

[0056] The sliding door assembly provided in this embodiment utilizes an upper limit stop on the sliding rack 220 to engage with the upward-facing surface of the sliding door 100, or utilizes an upper limit stop on the sliding door 100 to engage with the downward-facing surface of the sliding rack 220. In this way, the upward degree of freedom of the sliding door 100 can be restricted. The vertical degree of freedom of the sliding door 100 is an important indicator of the stable operation of the sliding door 100. Therefore, the locking screws used to lock the sliding door 100 and the sliding rack 220 can be greatly reduced or even eliminated.

[0057] During subsequent maintenance, the upper limit component can be removed to release the upward degree of freedom of the sliding door 100. Therefore, the sliding door assembly provided in this embodiment is easy to disassemble, which can reduce the time and manpower spent on subsequent disassembly and has high disassembly efficiency.

[0058] Specifically, a lower limit member can be provided on the sliding door 100. The lower limit member rolls with the upward-facing surface of the drive box 210 to restrict the downward degree of freedom of the sliding door 100. In other words, the lower limit member can bear the weight of the sliding door 100. The lower limit member and the upper limit member work together to restrict the vertical degree of freedom of the sliding door 100. Since the lower limit member only rests on the drive box 210 and there is no locking or fixed connection between them, the lower limit member can be disengaged from the drive box 210 when the sliding door 100 is lifted upward, thus disassembling the sliding door 100.

[0059] It should be noted that the size and number of the lower limit component can be set according to the needs of the sliding door 100. Correspondingly, since the upper limit component only needs to restrict the upward degree of freedom of the sliding door 100 and does not need to bear the weight of the sliding door 100, and the sliding door 100 is not easy to move upward, it hardly involves the balance of the sliding door 100. Therefore, the requirement for the number of the upper limit component is low, and it can be set to one (of course, it is also possible to set multiple).

[0060] Preferably, there is only one upper limit stop, and the upper limit stop is located in the middle of the circumference of the sliding door 100. This reduces the time and manpower spent on disassembly. In addition, when the sliding door 100 tends to move upward, the upper limit stop will prevent the sliding door 100 from continuing to move upward and will not easily become tilted due to unbalanced forces.

[0061] Preferably, see Figure 2 and Figure 7 A screw 400 can be used as the upper limit component. The screw 400 has a limiting section 410 and a connecting section 420. The limiting section 410 of the screw 400 is located between the connecting section 420 and the head of the screw 400. That is, the connecting section 420 is the tail end of the screw shank of the screw 400. The connecting section 420 of the screw 400 is threadedly connected to the sliding rack 220, and the limiting section 410 of the screw 400 is engaged with the upward-facing surface of the sliding door 100. In this way, the limiting section 410 of the screw 400 can restrict the upward freedom of the sliding door 100. In subsequent maintenance, the limitation on the upward freedom of the sliding door 100 can be released simply by unscrewing the screw 400, which is very convenient.

[0062] It should be noted that when the upper limit component is set to one, only one screw 400 needs to be removed to remove the sliding door 100. Compared with the existing technology that requires at least four locking screws to be removed, this greatly reduces the time and manpower required.

[0063] Specifically, the aforementioned screw 400 can be selected as a stepped screw, with the smooth section of the stepped screw set as the limiting section 410 and the threaded section of the stepped screw set as the connecting section 420. In this way, during assembly, the entire threaded section of the stepped screw can be screwed into the sliding rack 220 of the drive mechanism without controlling the length of screw 400 being screwed in, making installation simpler. In addition, by using the smooth section of the stepped screw to cooperate with the sliding door 100 for limiting, the wear caused by the interaction force between the stepped screw and the sliding door 100 can be reduced, and by screwing the entire threaded section of the stepped screw into the sliding rack 220, the connection reliability between the stepped screw and the sliding rack 220 can be improved.

[0064] Preferably, a gap is reserved between the head of the screw 400 and the sliding door 100. In this way, the sliding door 100 is not easily squeezed by the head of the screw 400 during the sliding process. As a result, the sliding door 100 is less likely to scratch the inner air outlet frame, and the requirements for screw 400 assembly can be reduced.

[0065] Specifically, the gap between the head of the screw 400 and the sliding door 100 can be set to 0.5mm.

[0066] Preferably, see Figure 2 and Figure 4 A groove 110 can be made on the top end face of the sliding door 100. The groove 110 is used to cooperate with the upper limit member. In this way, the groove 110 can form a certain limiting effect on the upper limit member, making it difficult for the upper limit member to fall out of the predetermined position, thus ensuring the reliability of the upper limit member in limiting the sliding door 100.

[0067] Specifically, the bearing 300 can be used as the lower limit component, which can greatly reduce the friction between the lower limit component and the drive box 210, reduce the sliding resistance of the sliding door 100, make the sliding door 100 slide more smoothly, improve the driving efficiency, and also reduce the wear on the drive box 210 and the lower limit component, thus extending their service life.

[0068] Furthermore, at least two lower limit members can be set and arranged at intervals along the horizontal direction. This will improve the support effect of the lower limit members on the sliding door 100, making the force on the sliding door 100 more balanced. As a result, the sliding door 100 is less likely to tilt, thus ensuring the smoothness of the sliding door 100.

[0069] In addition, a first limiting part can be provided on the sliding door 100, and correspondingly, a second limiting part can be provided on the sliding rack 200. The first limiting part and the second limiting part cooperate to limit the horizontal displacement of the sliding door 100 relative to the sliding rack 220 by using the second limiting part on the sliding rack 220.

[0070] Specifically, see Figures 2-6 A locking hole 120 is provided on the sliding door 100, and the extension direction of the locking hole 120 is set at an angle to the horizontal direction. At this time, the first limiting part includes the hole wall of the locking hole 120. Correspondingly, a protrusion 221 is provided on the sliding rack 220. The protrusion 221 can be inserted into the locking hole 120. At this time, the second limiting part includes the part of the protrusion 221 that cooperates with the hole wall of the locking hole 120. In this way, the protrusion 221 can limit the horizontal displacement of the sliding door 100 relative to the sliding rack 220, that is, the sliding door 100 can slide synchronously with the sliding rack 220. During subsequent maintenance, the sliding door 100 is lifted along the extension direction of the locking hole 120, and the protrusion 221 can be easily disengaged from the locking hole 120 without any other disassembly steps, ensuring the ease of disassembly.

[0071] Preferably, the extension direction of the card hole 120 is set to the vertical direction.

[0072] In the specific structure of the aforementioned drive mechanism, a power source, gears, and racks can be provided. The power source is installed in the drive box 210 and connected to the gear transmission so that the power source can drive the gear to rotate. The gear meshes with the rack, and when the gear rotates, it can drive the rack to slide along a set trajectory. The aforementioned sliding rack 220 includes a rack, so the rack can drive the sliding door 100 to slide. In addition, the upper limit member can transfer the rack's load to the sliding door 100, thereby reducing the rack's burden and allowing the rack to only play a driving role, improving the smoothness of the sliding door 100's operation.

[0073] This embodiment also provides an air conditioner that includes the above-described sliding door assembly.

[0074] The air conditioner provided in this embodiment has all the advantages of the sliding door assembly described above. It is easy to disassemble, which can reduce the time and manpower spent on subsequent disassembly and has high disassembly efficiency.

[0075] In summary, the embodiments of the present invention disclose a sliding door assembly and an air conditioner, which overcomes many technical defects of the sliding door limiting structure in traditional air conditioner indoor units. The sliding door assembly and air conditioner provided by the embodiments of the present invention are easy to disassemble, reducing the time and manpower required for subsequent disassembly, and have high disassembly efficiency.
