Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, particularly relates to a ceiling machine. BACKGROUND

[0002] The ceiling machine is a ceiling embedded air conditioner, also known as a ceiling machine, a ceiling machine or an embedded air conditioner. The ceiling embedded air conditioner is actually a kind of air conditioner indoor unit. The ceiling type air conditioner can be placed in the middle of the room, which is also the biggest advantage of the ceiling type air conditioner. The ceiling type air conditioner can be placed in the middle of the room, which means that the cold and heat can be better dispersed, so that the rapid cooling and heating can be achieved and the dead angle of cooling and heating can be better eliminated.

[0003] Due to different air conditioning use habits of different regions and different users, there is often a need to regularly clean the internal related components (such as the fan wheel, evaporator, etc.) of the ceiling machine. However, the ceiling machine is often installed on the ceiling. When cleaning the internal components of the ceiling machine, one way is to disassemble the entire machine from the ceiling, and then disassemble the internal related components for cleaning (or directly disassemble the related components from the internal installation state of the ceiling machine). This way results in a cumbersome and laborious cleaning process, and there is a certain risk of falling of the entire machine or the parts. Another way is to insert a water pipe into the internal part of the ceiling machine for flushing. This way requires the cleaning personnel to operate from a high place, often facing the risk of falling from a high place and the risk of cleaning water spilling, resulting in a difficult cleaning operation. At the same time, due to the obstruction of the internal components of the ceiling machine, it is easy to have a flushing dead zone in the internal part of the ceiling machine, resulting in poor cleaning effect. SUMMARY

[0004] Therefore, the present application aims to provide a ceiling machine to solve the problem that the operation of cleaning the fan wheel of the ceiling machine in the normal installation state is difficult and the fan wheel is easy to fall.

[0005] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows:

[0006] The utility model provides a ceiling machine, including chassis, wind wheel, elevating gear, one side of elevating gear is connected with chassis, the other side sets up the hanger piece that can move up and down, wind wheel sets up the mounting part, the hanger piece is connected with the mounting part in the way of being detachable, elevating gear drives wind wheel to move in vertical direction through the hanger piece, thereby in the normal installation state of ceiling machine, through setting up elevating gear, when needing to disassemble and wash wind wheel, hanger piece is connected with mounting part, then wind wheel is disassembled, subsequently wind wheel is driven to move to the ground vicinity through elevating gear, and the cleaning personnel can stand on the ground and directly wash wind wheel, on one hand, in the process of disassembling wind wheel, it is not necessary to lift wind wheel, and the falling of wind wheel is avoided, on the other hand, the cleaning personnel can safely and carefully directly wash wind wheel on the ground, greatly reduce the operation difficulty of wind wheel washing, and can effectively improve the washing effect of wind wheel.

[0007] Further, the elevating device comprises a first elevating assembly, the first elevating assembly comprises a first motor, a rotating shaft, a support frame and a flexible cable, one end of the rotating shaft is connected with a motor shaft of the first motor, the other end is rotatably connected with the support frame, the first motor and the support frame are connected with the chassis, the rotating shaft is provided with a winding groove, one end of the flexible cable is connected with the winding groove, the other end is provided with a hook, the flexible cable can be wound in the winding groove, and the hook is detachably connected with the mounting part. Thus, the first motor drives the rotating shaft to rotate, the flexible cable is released or wound, and the hook and the wind wheel are correspondingly driven to move downward or upward. The first elevating assembly has simple structure, stable and reliable transmission, and can simply and conveniently realize the lifting of the wind wheel.

[0008] Further, the rotating shaft is provided with a guard plate on both sides of the winding groove, which can effectively prevent the flexible cable, the hook and the wind wheel from shaking during the release or winding of the flexible cable, so that the wind wheel can rise or fall as stably as possible.

[0009] Further, the first elevating assembly comprises a speed reduction mechanism, the speed reduction mechanism comprises a gear and a speed reduction seat, the gear is coaxially arranged with the rotating shaft, the speed reduction seat is connected with the chassis, the side of the speed reduction seat facing the gear is provided with a speed reduction piece, the speed reduction piece abuts against the gear, and at least a deceleration resistance can be provided for the descending process of the wind wheel. Thus, the speed reduction mechanism can make the wind wheel descend stably during the descending process, avoid the falling speed of the wind wheel being too fast, and also avoid the situation that the wind wheel rapidly falls due to the pulling of the flexible cable in the case of sudden failure of the first motor. Even after the sudden failure of the first motor, the speed reduction mechanism can also provide a certain degree of locking effect to avoid the high-speed falling of the wind wheel.

[0010] Further, the end of the speed reduction piece away from the speed reduction base can be offset relative to the speed reduction base, the speed reduction piece is located directly above the rotating shaft, and the end of the speed reduction piece away from the speed reduction base is offset with the rotation of the gear, the gear is rotated in both forward and reverse directions by the offset speed reduction piece, and the rotating shaft and the gear are provided with certain speed reduction, so that the wind wheel is provided with certain speed reduction in the descending process and the ascending process.

[0011] Further, the speed reduction mechanism comprises a spring column, one end of the spring column is connected with the speed reduction base, and the other end of the spring column is connected with the speed reduction piece. Specifically, the rotating direction of the gear when the wind wheel is in the ascending state is denoted as M, the rotating direction of the gear when the wind wheel is in the descending state is denoted as N, the gear rotates in the M direction, the end of the speed reduction piece is offset towards the direction close to the spring column, the spring column is in a natural stretching state, the gear rotates in the N direction, the end of the speed reduction piece is offset towards the direction away from the spring column, and the spring column is in a forced stretching state or a forced compression state. Thus, when the wind wheel is in the descending state, the gear not only faces the speed reduction of the speed reduction piece, but also is subjected to the elastic force of the spring column, so that the speed reduction effect provided by the speed reduction mechanism in the descending process of the wind wheel is improved, the wind wheel can be slowly lowered more stably, and the falling speed of the wind wheel is prevented from being too fast.

[0012] Further, the ceiling machine comprises a wind guide ring, the wind guide ring has an air inlet, the wind wheel is arranged directly above the air inlet, and the minimum inner diameter of the air inlet is greater than the maximum outer diameter of the wind wheel. Thus, before the wind wheel is lowered for cleaning, only the panel of the ceiling machine needs to be removed to expose the air inlet, then the wind wheel is disassembled, and the wind wheel can be directly lowered down through the lifting device, so that the disassembly and assembly difficulty of the ceiling machine in the cleaning operation process of the wind wheel is further reduced.

[0013] Further, the lifting device comprises a second lifting assembly, the second lifting assembly comprises a hook and a plurality of slide rail pieces connected in sequence from top to bottom, any two adjacent slide rail pieces can relatively slide in the vertical direction, the hook has a connecting plate, the connecting plate is connected with the slide rail piece at the lowermost position, the connecting plate and the slide rail piece at the lowermost position can relatively slide in the vertical direction, and the hook is detachably mounted on the mounting portion.

DETAILED DESCRIPTION

[0032] The inventive concepts of the present disclosure will be described below using terms that the person skilled in the art usually uses to convey the substance of their work to other skilled persons in the art. However, these inventive concepts can be embodied in many different forms, and thus should not be considered limited to the embodiments described herein.

[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The orientation words in the present application, such as "upper" and "lower", are based on the normal assembly state of the ceiling, or intuitively, the ceiling is the upper part and the ground is the lower part. ​​

[0034] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] In the prior art, some users often have the need to regularly clean the internal related components (such as the fan wheel, evaporator, etc.) of the ceiling machine. However, the ceiling machine is often installed on the ceiling. When cleaning the internal components of the ceiling machine, one way is to disassemble the entire machine from the ceiling, and then disassemble the internal related components for cleaning (or directly disassemble the related components from the internal part of the installed ceiling machine). This way results in a cumbersome and laborious cleaning process, and there is a certain risk of falling of the entire machine or parts. Another way is to insert a water pipe into the internal part of the ceiling machine for flushing. This way requires the cleaning personnel to operate at a high place, often facing the risk of splashing of cleaning water and falling from a high place, resulting in a difficult cleaning operation. At the same time, due to the obstruction of the internal components of the ceiling machine, it is easy to have a flushing dead zone in the internal part of the ceiling machine, resulting in poor cleaning effect.

[0036] Embodiment 1

[0037] Specifically, taking the fan wheel 3 of the ceiling machine as an example, in the prior art, the ceiling machine in the normal installation state often has a difficult operation to clean the fan wheel, and even the fan wheel is prone to falling. In order to solve this problem in the prior art, the present embodiment proposes a ceiling machine as shown in the accompanying drawings. The ceiling machine comprises a chassis 1, a fan wheel 3, and a lifting device 5. One side of the lifting device 5 is connected with the chassis 1, and the other side is provided with a hanging piece capable of moving up and down. The fan wheel 3 is provided with a mounting part 31. The hanging piece is connected with the mounting part 31 in a detachable manner. The lifting device 5 drives the fan wheel 3 to move in the vertical direction through the hanging piece. Figures 1-11 Thus, in the normal installation state of the ceiling machine, when it is necessary to disassemble and clean the fan wheel 3, the hanging piece is connected with the mounting part 31, and then the fan wheel 3 is disassembled. Subsequently, the fan wheel 3 is driven by the lifting device 5 to move downward to the ground. The cleaning personnel can directly clean the fan wheel 3 on the ground. On the one hand, the fan wheel 3 does not need to be lifted during disassembly, which eliminates the falling of the fan wheel 3. On the other hand, the cleaning personnel can safely and carefully clean the fan wheel 3 directly on the ground, greatly reducing the operation difficulty of the fan wheel cleaning, and effectively improving the cleaning effect of the fan wheel 3. At the same time, after cleaning, the fan wheel 3 is driven upward by the lifting device 5, and then the fan wheel 3 is assembled and fixed with the motor 2. Then, the hanging piece is disassembled and separated from the mounting part 31.

[0038]

[0039] ​For the use state of the ceiling machine, the fixed connection of the wind wheel 3 and the motor 2 and the disassembly between the wind wheel 3 and the motor 2 belong to the conventional technology of the ceiling machine, and will not be repeated. The application focuses on introducing the protection, cleaning operation and other related contents of the wind wheel 3 in the disassembly process.

[0040] The lifting device 5 comprises a first lifting assembly 6, the first lifting assembly 6 comprises a first motor 62, a rotating shaft 61, a support frame 64 and a flexible cable 65, one end of the rotating shaft 61 is connected with the motor shaft of the first motor 62, the other end is rotatably connected with the support frame 64, the first motor 62 and the support frame 64 are connected with the bottom plate 1, the rotating shaft 61 is provided with a winding groove 63, one end of the flexible cable 65 is connected with the winding groove 63, and the other end is provided with a lifting hook 67, the flexible cable 65 can be wound in the winding groove 63, and the lifting hook 67 can hang the mounting part 31. Thus, the first motor 62 drives the rotating shaft 61 to rotate, releases or winds the flexible cable 65, and correspondingly drives the lifting hook 67 and the wind wheel 3 to move downward or upward, the first lifting assembly 6 is simple in structure, stable and reliable in transmission, and can simply and conveniently realize the lifting of the wind wheel 3. For the related parts connected with the bottom plate 1 in the lifting device 5, the mounting plate 621 can be arranged on the related parts, and the mounting plate 621 is connected with the bottom plate 1 by means of fasteners, so as to realize the fixed connection of the related parts and the bottom plate 1. In the drawings of the application, only the first motor 62 is provided with the mounting plate 621, and the other parts connected with the bottom plate 1 in the lifting device 5 can also be provided with the mounting plate 621, and details are not repeated. The lifting hook 67 can be regarded as a hanging part of the lifting device 5.

[0041] For the mounting part 31, it can be a flange at the edge of the wind wheel 3, or a hanging hole structure provided on the wind wheel 3, so as to facilitate the lifting hook 67 or other forms of hanging parts to lift the wind wheel 3.

[0042] The rotating shaft 61 is provided with a guard plate 631 on both sides of the winding groove 63, which can effectively prevent the flexible cable 65, the lifting hook 67 and the wind wheel 3 from shaking during the release or winding of the flexible cable 65, so that the wind wheel 3 can rise or fall as stably as possible.

[0043] The first lifting assembly 6 comprises a deceleration mechanism 66, the deceleration mechanism 66 comprises a gear 661 and a deceleration seat 662, the gear 661 is coaxially arranged with the rotating shaft 61, the deceleration seat 662 is connected with the chassis 1, a deceleration piece 663 is arranged on the side of the deceleration seat 662 facing the gear, the deceleration piece 663 abuts against the gear 661, and at least the deceleration piece 663 can provide deceleration resistance in the descending process of the wind wheel 3. Thus, by arranging the deceleration mechanism 66, the wind wheel 3 can be slowly lowered more stably in the descending process, the falling speed of the wind wheel 3 is avoided from being too fast, and in special cases such as sudden failure of the first motor 62, the wind wheel 3 is also avoided from being quickly lowered by the flexible cable 65. Even after the first motor 62 suddenly fails, the deceleration mechanism 66 can also provide a certain degree of locking effect to avoid the wind wheel 3 from falling at a high speed. Specifically, without considering the gear 661, one end of the deceleration piece 663 away from the deceleration seat 662 can be offset relative to the deceleration seat 662, the deceleration piece 663 is located directly above the rotating shaft 61, one end of the deceleration piece 663 is connected with the deceleration seat 662, and the other end extends towards the rotating shaft 61. Since the end of the deceleration piece 663 abuts against the gear 661, the one end of the deceleration piece 663 away from the deceleration seat 662 will be offset to a certain extent along with the rotation of the gear 661. The deceleration piece 663 after the offset generates resistance to the forward and reverse rotation of the gear 661, and provides a certain deceleration effect to the rotation of the rotating shaft 61 and the gear 661. Correspondingly, the deceleration piece 663 can provide a certain deceleration effect to the descending process and the ascending process of the wind wheel 3.

[0044] The deceleration mechanism 66 comprises a spring column 664, one end of the spring column 664 is connected with the deceleration seat 662, and the other end is connected with the deceleration piece 663. The rotating direction of the gear 661 when the wind wheel 3 is in the ascending state is denoted as M, and the rotating direction of the gear 661 when the wind wheel 3 is in the descending state is denoted as N. The gear 661 rotates in the M direction, the end of the deceleration piece 663 is offset towards the direction close to the spring column 664, the spring column 664 is in a natural stretching state, the gear 661 rotates in the N direction, the end of the deceleration piece 663 is offset towards the direction away from the spring column 664, and the spring column 664 is in a forced stretching state or a forced compression state. Thus, when the wind wheel 3 is in the descending state, the gear 661 not only faces the deceleration of the deceleration piece 663, but also receives the elastic force of the spring column 664, which can improve the deceleration effect provided by the deceleration mechanism 66 in the descending process of the wind wheel 3, so that the wind wheel 3 can be slowly lowered more stably to avoid the falling speed of the wind wheel 3 being too fast. At the same time, the resistance received by the wind wheel 3 when the wind wheel 3 is in the ascending state is relatively small, and the spring column 664 hardly provides resistance, so that the wind wheel 3 can be easily driven to ascend under the driving of the first motor 62.

[0045] Meanwhile, for conventional ceiling cleaning machines, the ceiling cleaning machine includes an air guide ring (not shown), the air guide ring has an air inlet, and the impeller 3 is usually located directly above the air inlet. As a preferred embodiment of this application, the minimum inner diameter of the air inlet is greater than the maximum outer diameter of the impeller 3, so that before the impeller 3 needs to be lowered for cleaning, it is only necessary to remove the panel of the ceiling cleaning machine to expose the air inlet, then disassemble the impeller 3, and the impeller 3 can be directly lowered by the lifting device 5, which helps to further reduce the difficulty of disassembling and assembling the ceiling cleaning machine during the impeller 3 cleaning operation.

[0046] In this embodiment, the ceiling machine is equipped with at least three first lifting components 6, which simultaneously suspend and lift the impeller 3 to ensure that the cylindrical impeller 3 can be lifted and lowered more smoothly, and that the impeller 3 is subjected to stable force during the lifting and lowering process, so that it will not tip over or overturn.

[0047] Example 2

[0048] Taking the evaporator 4 of a ceiling-mounted air conditioner as an example, in the prior art, cleaning the evaporator of a ceiling-mounted air conditioner under normal installation conditions is difficult and the cleaning effect is poor. In some cases, it is even necessary to remove the entire ceiling-mounted air conditioner from the ceiling to remove the evaporator for cleaning. To solve this problem in the prior art, this embodiment proposes a ceiling-mounted air conditioner, as shown in the attached figure. Figures 1-11 As shown, the ceiling-mounted unit includes a chassis 1, an evaporator 4, and a lifting device 5. One side of the lifting device 5 is connected to the chassis 1, and the other side is provided with a hanging component that can move up and down. The hanging component hangs the evaporator 4. The lifting device 5 drives the evaporator 4 to move in the vertical direction through the hanging component. The lifting device 5 includes a locking component 8, which is used to lock the hanging component after the evaporator 4 rises to the assembly position, so as to achieve a stable assembly of the evaporator 4.

[0049] Therefore, under normal installation conditions of the ceiling-mounted cleaning machine, this application, by setting up a lifting device 5, allows the evaporator 4 to be cleaned. When the evaporator 4 needs cleaning, the locking part 8 is opened, and the lifting device 5 moves the evaporator 4 downwards to near the ground. Cleaning personnel can then stand on the ground and directly clean the evaporator 4, allowing for safe and thorough cleaning. This significantly reduces the difficulty of evaporator cleaning and effectively improves the cleaning effect. After cleaning, the lifting device 5 moves the evaporator 4 upwards until it reaches the assembly position, where the locking part 8 locks the hanging components.

[0050] In addition, the cleaning process of the evaporator 4 avoids the disassembly of the entire air conditioner. In combination with the structure of the conventional air conditioner, in order to make the evaporator 4 fall to the ground, only the components below the evaporator need to be disassembled (such as the panel, air guide ring, and water pan of the air conditioner), which reduces the operation difficulty and improves the cleaning efficiency of the evaporator 4.

[0051] The lifting device 5 includes a second lifting assembly 7, which includes a hook 73 and a plurality of slide rail pieces 71 connected in sequence from top to bottom, any two adjacent slide rail pieces 71 can slide relative to each other in the vertical direction, and the hook 73 has a connecting plate 731 connected with the lowermost slide rail piece 71, and the connecting plate 731 can slide relative to the lowermost slide rail piece 71 in the vertical direction. Thus, the hook 73 can move up and down by mounting the evaporator 4 through the hook 73 and using a plurality of slide rail pieces 71 that can slide relative to each other in the vertical direction, which can correspondingly drive the evaporator 4 to rise or fall. The hook 73 can be regarded as a hanging piece of the lifting device 5.

[0052] The slide rail piece 71 and the connecting plate 731 are provided with locking holes 72, and the locking holes 72 of any two adjacent slide rail pieces 71 can be aligned with the sliding of the slide rail pieces 71, and the locking hole 72 of the connecting plate 731 can be aligned with the locking hole 72 of the slide rail piece 71 with the sliding of the connecting plate 731 and the slide rail piece 71. The locking piece 8 can penetrate the locking holes 72 to lock any two adjacent slide rail pieces 71 and / or the connecting plate 731 and the slide rail piece 71. Thus, by adjusting the relative sliding of each component in the second lifting assembly 7 and locking by the locking piece 8, the evaporator 4 can be raised or lowered to a certain height.

[0053] For the sliding between the slide rail pieces 71, the slide rail piece 71 has a slide rail cavity 711, and for any two adjacent slide rail pieces 71, the lower slide rail piece 71 is arranged in the slide rail cavity 711 of the upper slide rail piece 71, and any two adjacent slide rail pieces 71 can slide relative to each other along the slide rail cavity 711. Thus, the entire second lifting assembly 7 forms a structure that can be extended and retracted in the vertical direction, which can effectively drive the evaporator 4 to rise or fall. For the extension and retraction of the second lifting assembly 7, it can be a sleeve structure as shown in the accompanying drawings, or a telescopic slide rail structure. Figures 6-11

[0054] ​The lower end of the slide rail piece 71 is provided with a limiting table 712 extending towards the inner direction of the slide rail piece 71, and the upper end of the slide rail piece 71 is provided with a first limiting seat 713 extending towards the outer direction of the slide rail piece 71; for any two adjacent slide rail pieces 71, the limiting table 712 of the slide rail piece 71 located above can abut against the first limiting seat 713 of the slide rail piece 71 located below. Thus, the two adjacent slide rail pieces 71 will not be separated when being stretched downwards, and the normal stretching of the second lifting assembly 7 is ensured. For the hook 73, the upper end of the connecting plate 731 is provided with a limiting piece 732 which can abut against the limiting table 712 of the slide rail piece 71 located at the lowermost position.

[0055] In addition, for any two adjacent slide rail pieces 71, the first limiting seat 713 of the slide rail piece 71 located below can abut against the side wall of the slide rail cavity 711 of the slide rail piece 71 located above, which is beneficial to ensure that the two adjacent slide rail pieces 71 can be smoothly stretched, and unnecessary shaking of the second lifting assembly 7 during the stretching process is avoided. For the hook 73, the limiting piece 732 can abut against the side wall of the slide rail cavity 711 of the slide rail piece 71 located at the lowermost position.

[0056] The upper end of the slide rail piece 71 is provided with a second limiting seat 714 extending towards the inner direction of the slide rail piece 71; for any two adjacent slide rail pieces 71, the first limiting seat 713 of the slide rail piece 71 located below can abut against the second limiting seat 714 of the slide rail piece 71 located above, so that the two adjacent slide rail pieces 71 will not be separated when being retracted upwards, and the normal retraction of the second lifting assembly 7 is ensured; at the same time, in combination with the common limiting of the second limiting seat 714 and the limiting table 712, the two adjacent slide rail pieces 71 can only slide within a small space in the vertical direction, and will not be separated, which is beneficial to ensure the stability of the extension and retraction of the entire second lifting assembly 7. For the hook 73, the limiting piece 732 can abut against the second limiting seat 714 of the slide rail piece 71 located at the lowermost position.

[0057] The upper end of the second lifting assembly 7 is provided with a fixing seat 74, and the second lifting assembly 7 is connected with the bottom disc 1 through the fixing seat 74, specifically, the upper end of the slide rail piece 71 located at the uppermost position is provided with the fixing seat 74. Two forms of the fixing seat 74 are proposed in the embodiment.

[0058] Form one, the fixing seat 74 is a flange at the upper end of the slide rail piece 71 located at the uppermost position, and the flange is provided with an assembly hole, and the flange can be connected with the bottom disc 1 through a fastener to realize the connection between the second lifting assembly 7 and the bottom disc 1.

[0059] Form two, the fixed seat 74 is a support seat, one end of which is connected with the chassis 1, and the other end is connected with the upper end of the second lifting assembly 7.

[0060] In this embodiment, form two is preferred, the second lifting assembly 7 includes a traction mechanism 742, a containing cavity is formed between the fixed seat 74 and the chassis 1, the traction mechanism 742 connected with the chassis 1 is arranged in the containing cavity, the traction rope 741 of the traction mechanism 742 extends into the slide rail cavity 711 of the slide rail piece 71 until it is connected with the connecting plate 731 of the hook 73. By arranging the traction mechanism 742, on the one hand, the second lifting assembly 7 can automatically lift and lower the evaporator 4, greatly reducing the operation difficulty and operation risk of people when lifting and lowering the evaporator 4, on the other hand, the telescopic form of the slide rail piece 71 is combined with the traction mechanism 742, so that the evaporator 4 can be lowered more stably, and shaking does not occur, and double insurance is provided for preventing accidental falling of the evaporator 4. For the traction mechanism 742, it includes a second motor 7422 and a rope roller 7421, the second motor 7422 is connected with the rope roller 7421 for driving the rope roller 7421 to rotate, realizing the release or winding of the traction rope 741, one end of the traction rope 741 is connected with the rope roller 7421, and the other end is connected with the connecting plate 731 of the hook 73, and the traction rope 741 can be wound on the rope roller 7421.

[0061] In this embodiment, the ceiling machine is provided with at least three second lifting assemblies 7, which simultaneously hang and lift the evaporator 4, so as to ensure that the evaporator 4 can be lifted more stably, and the evaporator 4 is stressed stably during lifting and does not overturn or turn over.

[0062] Embodiment 3

[0063] In this embodiment, the first lifting assembly 6 in embodiment 1 is replaced with the second lifting assembly 7 in embodiment 2 on the basis of embodiment 1. At the same time, this embodiment maintains the related original content and lifting form of the second lifting assembly 7 in embodiment 2, and only changes the hanging object of the second lifting assembly 7 from the evaporator 4 to the fan wheel 3. Since there is some repetition in the related text content, this embodiment will not be described here.

[0064] Meanwhile, the hook 73 of the second lifting assembly 7 is detachably connected with the mounting part 31 of the wind wheel 3, so that the hook 73 is not always in contact with the wind wheel 3, but only provides mounting for the wind wheel 3 when it is necessary to lift or dismount the wind wheel 3. Since the wind wheel 3 has relatively small weight, in a specific implementation, the hook 73 can be a flexible member, and the mounting and dismounting between the hook 73 and the mounting part 31 can be realized by exerting a certain force to change the shape or orientation of the hook 73. Alternatively, the second lifting assembly 7 can be rotatably connected with the chassis 1 (or the hook 73 can be rotatable relative to the second lifting assembly 7), and the mounting and dismounting between the hook 73 and the mounting part 31 can be realized by rotating the second lifting assembly 7 (or rotating the hook 73) to change the orientation of the hook 73.

[0065] In addition, the first lifting assembly 6 in Embodiment 1 and the second lifting assembly 7 in Embodiment 2 can also be simultaneously provided in the ceiling machine, and the first lifting assembly 6 and the second lifting assembly 7 can be simultaneously used to mount and lift the wind wheel 3.

[0066] Embodiment 4

[0067] In this embodiment, the second lifting assembly 7 in Embodiment 2 is replaced with the first lifting assembly 6 in Embodiment 1. Meanwhile, this embodiment maintains the related original content and lifting form of the first lifting assembly 6 in Embodiment 1, and only changes the mounting object of the first lifting assembly 6 from the wind wheel 3 to the evaporator 4. Since the related text content is repetitive, this embodiment will not be described in detail.

[0068] Meanwhile, since the evaporator 4 often needs to be always mounted, the hook 67 of the first lifting assembly 6 in this embodiment is always in contact with the evaporator 4, and always maintains the mounting of the evaporator 4.

[0069] In addition, the first lifting assembly 6 in Embodiment 1 and the second lifting assembly 7 in Embodiment 2 can also be simultaneously provided in the ceiling machine, and the first lifting assembly 6 and the second lifting assembly 7 can be simultaneously used to mount and lift the evaporator 4.

[0071] The above only describes the preferred embodiments of the present application and should not be used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
