Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a ceiling air conditioner. Background Art

[0002] A ceiling air conditioner is a type of ceiling embedded air conditioner, also known as a ceiling air conditioner, a patio air conditioner or an embedded air conditioner. A ceiling embedded air conditioner is actually a type of indoor air conditioner. A ceiling air conditioner can be placed in the middle of the room, which is also the biggest advantage of a ceiling air conditioner. Being able to place it in the middle of the room means that the cold and heat can be better diffused, which can not only achieve rapid cooling and heating, but also better eliminate the dead corners of cooling and heating.

[0003] Due to the different air conditioning usage habits of different regions and users, there is often a need to regularly clean the relevant parts inside the ceiling unit (such as the impeller, evaporator, etc.). However, ceiling units are often installed on the ceiling. When cleaning the internal parts of the ceiling unit, one way is to remove the entire unit from the ceiling, and then remove the relevant internal parts from the ceiling unit for cleaning (or directly remove the relevant parts from the installed ceiling unit). This method makes the entire cleaning process troublesome and laborious, and there is a certain risk of the entire unit falling or parts falling; another way is to insert a water pipe into the ceiling unit for flushing. This method requires the cleaning personnel to stand at a high place to operate, and they often face the risk of spilling cleaning water and falling from a high altitude, making the cleaning operation more difficult. At the same time, due to the obstruction of the internal parts of the ceiling unit, it is also easy to have a flushing dead zone inside the ceiling unit, resulting in poor cleaning effect. Summary of the invention

[0004] In view of this, the present invention aims to provide a ceiling machine to solve the problem in the prior art that it is difficult to clean the wind wheel of the ceiling machine in a normal installation state, and the wind wheel is even prone to falling.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A ceiling machine includes a chassis, a wind wheel, and a lifting device. One side of the lifting device is connected to the chassis, and the other side is provided with a hanging part that can move up and down. The wind wheel is provided with a mounting part, and the hanging part is connected to the mounting part in a detachable manner. The lifting device drives the wind wheel to move in the vertical direction through the hanging part. Therefore, when the ceiling machine is normally installed, by setting the lifting device, when it is necessary to disassemble and clean the wind wheel, the hanging part is connected to the mounting part, and then the wind wheel is disassembled, and then the wind wheel is driven by the lifting device to move downward to the vicinity of the ground, and the cleaning personnel can stand on the ground to directly clean the wind wheel. On the one hand, during the disassembly process of the wind wheel, there is no need to lift the wind wheel, which prevents the wind wheel from falling. On the other hand, the cleaning personnel can safely and carefully clean the wind wheel directly on the ground, which greatly reduces the difficulty of cleaning the wind wheel and can effectively improve the cleaning effect of the wind wheel. At the same time, after cleaning, the wind wheel is driven to move upward by the lifting device, and then the wind wheel and the motor are assembled and fixed, and then the hanging part and the mounting part are disassembled and separated.

[0007] Furthermore, the lifting device includes a first lifting component, which includes a first motor, a rotating shaft, a support frame, and a flexible cable. One end of the rotating shaft is connected to the motor shaft of the first motor, and the other end is connected to the support frame in a rotatable manner. The first motor and the support frame are both connected to the chassis. The rotating shaft is provided with a winding groove, one end of the flexible cable is connected to the winding groove, and the other end is provided with a hook. The flexible cable can be wound in the winding groove, and the hook is used to hang the mounting part in a detachable manner. Thus, the first motor drives the rotating shaft to rotate, and the flexible cable is released or reeled in, which drives the hook and the wind wheel to move downward or upward accordingly. The first lifting component has a simple structure, stable and reliable transmission, and can realize the lifting and lowering of the wind wheel simply and conveniently.

[0008] Furthermore, the rotating shaft is provided with guard plates 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 reeling of the flexible cable, so that the wind wheel can rise or fall as smoothly as possible.

[0009] Furthermore, the first lifting assembly includes a deceleration mechanism, which includes a gear and a deceleration seat. The gear is coaxially arranged with the rotating shaft, and the deceleration seat is connected to the chassis. A deceleration plate is arranged on the side of the deceleration seat facing the gear, and the deceleration plate abuts against the gear, which can at least provide deceleration resistance for the descent process of the wind wheel. Therefore, by setting the deceleration mechanism, the wind wheel can be slowly lowered relatively smoothly during the descent process, and the wind wheel can be prevented from falling too fast. At the same time, in special circumstances such as the sudden failure of the first motor, the situation that the wind wheel drags the flexible rope and falls quickly can also be avoided. Even after the sudden failure of the first motor, the deceleration mechanism can still provide a certain degree of locking effect to prevent the wind wheel from falling at high speed.

[0010] Furthermore, the end of the speed reduction plate away from the speed reduction seat can be offset relative to the speed reduction seat. The speed reduction plate is located directly above the rotating shaft. The end of the speed reduction plate away from the speed reduction seat will be offset as the gear rotates. The offset speed reduction plate generates resistance to both the forward and reverse rotation of the gear, thereby providing a certain deceleration effect on the rotation of the rotating shaft and the gear, thereby providing a certain deceleration effect on the descent and ascent processes of the wind wheel.

[0011] Furthermore, the deceleration mechanism includes a spring column, one end of which is connected to the deceleration seat, and the other end is connected to the deceleration plate. Specifically, the gear rotation direction when the wind wheel is in the ascending state is recorded as M, and the gear rotation direction when the wind wheel is in the descending state is recorded as N. The gear rotates in the M direction, and the end of the deceleration plate is offset toward the direction close to the spring column. The spring column is in a naturally extended state. The gear rotates in the N direction, and the end of the deceleration plate is offset toward the direction away from the spring column. The spring column is in a stressed tensile state or a stressed compressed state. Therefore, when the wind wheel is in a descending state, the gear is not only subject to the deceleration of the deceleration plate, but also to the elastic force of the spring column, which can improve the deceleration effect provided by the deceleration mechanism during the descending process of the wind wheel, so that the wind wheel can be slowly descended more smoothly, and the wind wheel can be prevented from falling too fast.

[0012] Furthermore, the ceiling machine includes an air guide ring, the air 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. Therefore, before the wind wheel needs to be dropped for cleaning, it is only necessary to remove the panel of the ceiling machine to expose the air inlet, then remove the wind wheel, and directly drop the wind wheel through the lifting device, which is conducive to further reducing the difficulty of disassembling and assembling the ceiling machine during the wind wheel cleaning operation.

[0013] Furthermore, the lifting device includes a second lifting component, which includes a hook and a plurality of slide rails connected in sequence from top to bottom, any two adjacent slide rails can slide relative to each other in the vertical direction, the hook has a connecting plate, the connecting plate is connected to the slide rail located at the bottom, the connecting plate and the slide rail located at the bottom can slide relative to each other in the vertical direction, and the hook mounts the mounting part in a detachable manner. Thus, while the wind wheel is mounted by the hook, the hook can move up and down by using a plurality of slide rails that can slide relative to each other in the vertical direction, and can also drive the wind wheel to rise or fall accordingly.

[0014] Furthermore, the lifting device includes a locking member, and the slide rail member and the connecting plate are both provided with locking holes, and the locking member can penetrate the locking hole, and is used to lock at least two adjacent slide rail members, and / or to lock the connecting plate and the slide rail member, so that the wind wheel can rise or fall to a specific height. Thus, by adjusting the relative sliding conditions of each component in the second lifting assembly and locking the locking member, the wind wheel can rise or fall to a specific height.

[0015] Compared with the prior art, the ceiling machine described in the present invention has the following advantages:

[0016] The ceiling machine described in the present invention, when the ceiling machine is normally installed, by setting a lifting device, when it is necessary to dismantle and clean the wind wheel, the hanging part is connected to the mounting part, and then the wind wheel is dismantled, and then the wind wheel is driven by the lifting device to move downward to the ground, and the cleaning personnel can stand on the ground to clean the wind wheel directly. On the one hand, during the dismantling process of the wind wheel, there is no need to lift the wind wheel, thereby preventing the wind wheel from falling. On the other hand, the cleaning personnel can directly clean the wind wheel safely and carefully on the ground, which greatly reduces the operational difficulty of cleaning the wind wheel and can also effectively improve the cleaning effect of the wind wheel.

[0017] At the same time, after cleaning is completed, the wind wheel is driven upward by the lifting device, and then the wind wheel and the motor are assembled and fixed, and then the hanging part and the mounting part are disassembled and separated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0033] It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. The directional terms in this application, such as "upper" and "lower", are based on the normal assembly state of the ceiling machine, or intuitively speaking, the ceiling is above and the ground is below.

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

[0035] In the existing ceiling technology, some users often have the need to regularly clean the relevant parts inside the ceiling machine (such as the impeller, evaporator, etc.). However, the ceiling machine is often installed on the ceiling. When cleaning the internal parts of the ceiling machine, one way is to remove the whole machine from the ceiling, and then remove the relevant internal parts from the ceiling machine for cleaning (or directly remove the relevant parts from the installed ceiling machine). This method makes the entire cleaning process troublesome and laborious, and there is a certain risk of the whole machine falling or parts falling; another way is to insert a water pipe into the ceiling machine for flushing. This method requires the cleaning personnel to stand at a high place to operate, and they often face the risk of spilling cleaning water and falling from a high altitude, which makes the cleaning operation more difficult. At the same time, due to the obstruction of the internal parts of the ceiling machine, it is also easy to have a flushing dead zone inside the ceiling machine, resulting in poor cleaning effect.

[0036] Example 1

[0037] Taking the wind wheel 3 of the ceiling machine as an example, in the prior art, when the ceiling machine is normally installed, it is often difficult to clean the wind wheel, and the wind wheel is even prone to fall. In order to solve this problem in the prior art, this embodiment proposes a ceiling machine, as shown in the attached Figure 1-11 As shown, the ceiling machine includes a chassis 1, a wind wheel 3, 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 part that can move up and down. The wind wheel 3 is provided with a mounting part 31, and the hanging part is connected to the mounting part 31 in a detachable manner. The lifting device 5 drives the wind wheel 3 to move in the vertical direction through the hanging part.

[0038] Therefore, when the ceiling machine is normally installed, the present application sets a lifting device 5. When the wind wheel 3 needs to be disassembled and cleaned, the hanging part is connected to the mounting part 31, and then the wind wheel 3 is disassembled. Then, the wind wheel 3 is driven downward to the ground by the lifting device 5, and the cleaning personnel can stand on the ground and directly clean the wind wheel 3. On the one hand, during the disassembly of the wind wheel 3, there is no need to lift the wind wheel 3, which prevents the wind wheel 3 from falling. On the other hand, the cleaning personnel can directly clean the wind wheel 3 safely and carefully on the ground, which greatly reduces the difficulty of cleaning the wind wheel and can effectively improve the cleaning effect of the wind wheel 3. At the same time, after the cleaning is completed, the wind wheel 3 is driven upward by the lifting device 5, and then the wind wheel 3 is assembled and fixed with the motor 2, and then the hanging part is disassembled and separated from the mounting part 31.

[0039] When the ceiling machine is in use, the fixed connection between the wind wheel 3 and the motor 2 and the disassembly and assembly between the wind wheel 3 and the motor 2 belong to the conventional technology of the ceiling machine and will not be described in detail. This application focuses on introducing the protection and cleaning operations of the wind wheel 3 during the disassembly process.

[0040] The lifting device 5 includes a first lifting assembly 6, which includes 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 to the motor shaft of the first motor 62, and the other end is connected to the support frame 64 in a rotatable manner. The first motor 62 and the support frame 64 are both connected to the chassis 1. The rotating shaft 61 is provided with a winding groove 63, one end of the flexible cable 65 is connected to the winding groove 63, and the other end is provided with a hook 67. The flexible cable 65 can be wound in the winding groove 63, and the hook 67 can hang the mounting part 31. Therefore, the rotating shaft 61 is driven to rotate by the first motor 62 to release or reel in the flexible cable 65, and the hook 67 and the wind wheel 3 are driven to move downward or upward accordingly. The first lifting assembly 6 has a simple structure, stable and reliable transmission, and can simply and conveniently realize the lifting and lowering of the wind wheel 3. For the relevant parts of the lifting device 5 connected to the chassis 1, a mounting plate 621 can be provided on the relevant parts, and the mounting plate 621 can be connected to the chassis 1 by fasteners to achieve fixed connection between the relevant parts and the chassis 1. In the drawings of this application, only the first motor 62 is provided with a mounting plate 621. For other parts of the lifting device 5 connected to the chassis 1, the same can be applied, and no further description is given. The hook 67 can be regarded as a hanging part of the lifting device 5.

[0041] The mounting portion 31 may be a flange at the edge of the wind wheel 3 or a hanging hole provided on the wind wheel 3, so as to facilitate hanging of the wind wheel 3 by a hook 67 or other forms of hanging parts.

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

[0043] The first lifting assembly 6 includes a deceleration mechanism 66, which includes a gear 661 and a deceleration seat 662. The gear 661 is coaxially arranged with the rotating shaft 61, and the deceleration seat 662 is connected to the chassis 1. The deceleration seat 662 is provided with a deceleration plate 663 on the side facing the gear, and the deceleration plate 663 abuts against the gear 661, and can at least provide deceleration resistance for the descending process of the wind wheel 3. Therefore, by providing the deceleration mechanism 66, the wind wheel 3 can be slowly lowered relatively smoothly during the descending process, and the wind wheel 3 can be prevented from falling too fast. At the same time, in special cases such as the sudden failure of the first motor 62, the situation that the wind wheel 3 drags the flexible rope 65 to fall quickly can also be avoided. Even after the sudden failure of the first motor 62, the deceleration mechanism 66 can still provide a certain degree of locking effect to prevent the wind wheel 3 from falling at a high speed. Specifically, without considering the gear 661, the end of the speed reducer 663 away from the speed reducer seat 662 can produce a certain offset relative to the speed reducer seat 662. The speed reducer 663 is located directly above the rotating shaft 61, one end of the speed reducer 663 is connected to the speed reducer seat 662, and the other end extends toward the rotating shaft 61. Since the end of the speed reducer 663 abuts against the gear 661, the end of the speed reducer 663 away from the speed reducer seat 662 will be offset to a certain extent as the gear 661 rotates. The offset speed reducer 663 generates resistance to the forward and reverse rotation of the gear 661, and provides a certain deceleration effect on the rotation of the rotating shaft 61 and the gear 661. Accordingly, it can provide a certain deceleration effect on the descending process and the ascending process of the wind wheel 3.

[0044] The deceleration mechanism 66 includes a spring column 664, one end of which is connected to the deceleration seat 662, and the other end is connected to the deceleration plate 663. The rotation direction of the gear 661 when the wind wheel 3 is in the ascending state is recorded as M, and the rotation direction of the gear 661 when the wind wheel 3 is in the descending state is recorded as N. The gear 661 rotates in the M direction, and the end of the deceleration plate 663 is offset in the direction close to the spring column 664. The spring column 664 is in a naturally extended state. The gear 661 rotates in the N direction, and the end of the deceleration plate 663 is offset in the direction away from the spring column 664. The spring column 664 is in a tension state or a compression state. Therefore, when the wind wheel 3 is in the descending state, the gear 661 is not only subject to the deceleration of the deceleration plate 663, but also to the elastic force of the spring column 664, which can improve the deceleration effect provided by the deceleration mechanism 66 during the descending process of the wind wheel 3, so that the wind wheel 3 can be slowly descended more smoothly, and the wind wheel 3 is prevented from falling too fast. At the same time, when the wind wheel 3 is in the ascending state, the resistance encountered is relatively small, and the spring column 664 provides almost no resistance, so the wind wheel 3 can be driven to ascend relatively easily under the drive of the first motor 62 .

[0045] At the same time, for a conventional ceiling machine, the ceiling machine includes an air guide ring (not shown), the air guide ring has an air inlet, and the wind wheel 3 is often arranged directly above the air inlet. As a preferred embodiment of the present application, the minimum inner diameter of the air inlet is larger than the maximum outer diameter of the wind wheel 3, so that before the wind wheel 3 needs to be dropped for cleaning, it is only necessary to remove the panel of the ceiling machine to expose the air inlet, and then remove the wind wheel 3, and the wind wheel 3 can be directly lowered through the lifting device 5, which is conducive to further reducing the difficulty of disassembly and assembly of the ceiling machine during the cleaning operation of the wind wheel 3.

[0046] In this embodiment, the ceiling machine is provided with at least three first lifting assemblies 6, which simultaneously suspend and lift the wind wheel 3 to ensure that the cylindrical wind wheel 3 can be lifted and lowered more smoothly, and at the same time, the wind wheel 3 is subjected to stable force during the lifting process and will not tip over or flip over.

[0047] Example 2

[0048] Taking the evaporator 4 of the ceiling machine as an example, in the prior art, when the ceiling machine is normally installed, it is difficult to clean the evaporator, the cleaning effect is poor, and the entire ceiling machine needs to be removed from the ceiling and the evaporator needs to be taken out for cleaning. In order to solve this problem in the prior art, this embodiment proposes a ceiling machine, as shown in the attached Figure 1-11 As shown, the ceiling machine 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 part that can move up and down. The hanging part mounts the evaporator 4. The lifting device 5 drives the evaporator 4 to move in the vertical direction through the hanging part. The lifting device 5 includes a locking part 8, which is used to lock the hanging part after the evaporator 4 rises to the assembly position to achieve a stable assembly of the evaporator 4.

[0049] Therefore, when the ceiling machine is normally installed, the present application sets a lifting device 5. When the evaporator 4 needs to be cleaned, the locking member 8 is opened, and the evaporator 4 is driven downward to the ground by the lifting device 5, so that the cleaning personnel can stand on the ground and directly clean the evaporator 4, so that the cleaning personnel can safely and carefully clean the evaporator 4 directly on the ground, which greatly reduces the difficulty of cleaning the evaporator and can effectively improve the cleaning effect of the evaporator 4. At the same time, after cleaning, the evaporator 4 is driven upward by the lifting device 5 until the evaporator 4 rises to the assembly position, and the hanging member can be locked by the locking member 8.

[0050] In addition, the cleaning process of the evaporator 4 also avoids the need to disassemble the entire ceiling machine. In view of the structure of a conventional ceiling machine, in the present application, before cleaning the evaporator 4, in order to allow the evaporator 4 to fall to the ground, it is only necessary to remove the components that are space-blocking under the evaporator (such as the panel, air guide ring, and water tray of the ceiling machine). Compared with removing the entire ceiling machine from the ceiling, the difficulty of operation is reduced and the efficiency of cleaning the evaporator 4 is improved.

[0051] The lifting device 5 includes a second lifting assembly 7, which includes a hook 73 and a plurality of slide rails 71 connected in sequence from top to bottom, and any two adjacent slide rails 71 can slide relative to each other in the vertical direction. The hook 73 has a connecting plate 731, and the connecting plate 731 is connected to the slide rail 71 located at the bottom, and the connecting plate 731 and the slide rail 71 located at the bottom can slide relative to each other in the vertical direction. Therefore, the present application uses the hook 73 to mount the evaporator 4, and utilizes a plurality of slide rails 71 that can slide relative to each other in the vertical direction, so that the hook 73 can move up and down, and correspondingly can also drive the evaporator 4 to rise or fall. The hook 73 can be regarded as a hanging member of the lifting device 5.

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

[0053] For the sliding between the slide rail members 71, the slide rail members 71 have a slide rail cavity 711. For any two adjacent slide rail members 71, the lower slide rail member 71 is arranged in the slide rail cavity 711 of the upper slide rail member 71, and any two adjacent slide rail members 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 as shown in the attached figure. Figure 6-11 The sleeve type structure shown in the figure can also be a telescopic slide rail structure.

[0054] A limit platform 712 is provided at the lower end of the slide rail member 71, and the limit platform 712 extends toward the inner direction of the slide rail member 71. A first limit seat 713 is provided at the upper end of the slide rail member 71, and the first limit seat 713 extends toward the outer direction of the slide rail member 71. For any two adjacent slide rail members 71, the limit platform 712 of the upper slide rail member 71 can abut against the first limit seat 713 of the lower slide rail member 71. Thus, any two adjacent slide rail members 71 will not separate when extending downward, ensuring the normal extension of the second lifting assembly 7. For the hook 73, a limit member 732 is provided at the upper end of the connecting plate 731, and the limit member 732 can abut against the limit platform 712 of the lowermost slide rail member 71.

[0055] In addition, for any two adjacent rail members 71, the first stopper 713 of the lower rail member 71 abuts against the side wall of the rail cavity 711 of the upper rail member 71, which helps to ensure that the two adjacent rail members 71 can be extended smoothly and avoid unnecessary shaking of the second lifting assembly 7 during the extension process. For the hook 73, the stopper 732 abuts against the side wall of the rail cavity 711 of the lower rail member 71.

[0056] The upper end of the slide rail member 71 is provided with a second limiting seat 714, and the first limiting seat 713 extends toward the inner direction of the slide rail member 71; for any two adjacent slide rail members 71, the first limiting seat 713 of the lower slide rail member 71 can abut against the second limiting seat 714 of the upper slide rail member 71, so that any two adjacent slide rail members 71 will not separate when they are retracted upward, ensuring the normal retraction of the second lifting assembly 7; at the same time, combined with the common limiting of the second limiting seat 714 and the limiting platform 712, any two adjacent slide rail members 71 can only slide within a small space in the vertical direction, and will not separate from each other, which is conducive to ensuring the telescopic stability of the entire second lifting assembly 7. For the hook 73, the limiting member 732 can abut against the second limiting seat 714 of the lowermost slide rail member 71.

[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 to the chassis 1 through the fixing seat 74, specifically, the upper end of the uppermost slide rail 71 is provided with a fixing seat 74. This embodiment proposes two configuration forms of the fixing seat 74.

[0058] In form one, the fixing seat 74 is a flange located at the upper end of the uppermost slide rail member 71 , and the flange is provided with an assembly hole. The flange can be connected to the chassis 1 through a fastener to achieve the connection between the second lifting assembly 7 and the chassis 1 .

[0059] In form two, the fixing seat 74 is a supporting seat, one end of which is connected to the chassis 1 , and the other end of which is connected to the upper end of the second lifting assembly 7 .

[0060] In this embodiment, the second form is preferred, the second lifting assembly 7 includes a traction mechanism 742, a receiving cavity is formed between the fixing seat 74 and the chassis 1, the receiving cavity is provided with a traction mechanism 742 connected to the chassis 1, and the traction rope 741 of the traction mechanism 742 extends into the slide rail cavity 711 of the slide rail member 71 until it is connected with the connecting plate 731 of the hook 73. Thus, by providing the traction mechanism 742, on the one hand, the second lifting assembly 7 can automatically lift the evaporator 4, greatly reducing the difficulty and risk of operation when people lift the evaporator 4, and on the other hand, the telescopic form of the slide rail member 71 is combined with the traction mechanism 742, so that the evaporator 4 can be lowered more smoothly without shaking, and at the same time, it also provides a "double insurance" to prevent the evaporator 4 from falling accidentally. The traction mechanism 742 includes a second motor 7422 and a rope roller 7421. The second motor 7422 is connected to the rope roller 7421 and is used to drive the rope roller 7421 to rotate, thereby releasing or winding up the traction rope 741. One end of the traction rope 741 is connected to the rope roller 7421, and the other end is connected to the connecting plate 731 of the hook 73. The traction rope 741 can be wound around the rope roller 7421.

[0061] In this embodiment, the ceiling machine is provided with at least three second lifting assemblies 7 to suspend and lift the evaporator 4 at the same time, so as to ensure that the evaporator 4 can be lifted and lowered more smoothly, and the evaporator 4 is subjected to a stable force during the lifting process without tipping or overturning.

[0062] Example 3

[0063] In this embodiment, on the basis of the embodiment 1, the first lifting assembly 6 in the embodiment 1 is replaced by the second lifting assembly 7 in the embodiment 2. Meanwhile, the relevant original content and lifting form of the second lifting assembly 7 in the embodiment 2 are maintained in this embodiment, and only the mounting object of the second lifting assembly 7 is changed from the evaporator 4 to the wind wheel 3. In view of the certain repetition of the relevant text content, this embodiment will not be repeated.

[0064] At the same time, the hook 73 of the second lifting assembly 7 is connected to the mounting portion 31 of the wind wheel 3 in a detachable manner, 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 disassemble the wind wheel 3. In view of the relatively small weight of the wind wheel 3, the specific implementation form can be that the hook 73 is a flexible member, and the shape or orientation of the hook 73 is changed by applying a certain force to achieve mounting and unmounting between the hook 73 and the mounting portion 31; or the second lifting assembly 7 can be connected to the chassis 1 in a rotatable manner (or the hook 73 itself can rotate relative to the second lifting assembly 7), and the hook 73 is oriented by rotating the second lifting assembly 7 (or rotating the hook 73) to achieve mounting and unmounting between the hook 73 and the mounting portion 31.

[0065] In addition, in this embodiment, the first lifting assembly 6 in embodiment 1 and the second lifting assembly 7 in embodiment 2 can be simultaneously arranged in the ceiling machine, and the first lifting assembly 6 and the second lifting assembly 7 can be used to mount and lift the wind wheel 3 at the same time.

[0066] Example 4

[0067] This embodiment is based on the embodiment 2, and the second lifting assembly 7 in the embodiment 2 is replaced by the first lifting assembly 6 in the embodiment 1. At the same time, this embodiment maintains the relevant original content and lifting form of the first lifting assembly 6 in the embodiment 1, and only changes the mounting object of the first lifting assembly 6 from the wind wheel 3 to the evaporator 4. In view of the certain repetition of the relevant text content, this embodiment does not repeat it.

[0068] At the same time, since the evaporator 4 often needs to be kept in a mounted state all the time, 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, in this embodiment, the first lifting assembly 6 in embodiment 1 and the second lifting assembly 7 in embodiment 2 can be simultaneously arranged in the ceiling machine, and the first lifting assembly 6 and the second lifting assembly 7 can be used to mount and lift the evaporator 4 at the same time.
