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, the 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 ceiling machine in the installed state). 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 splashing of cleaning water, 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 problems of difficult operation and poor cleaning effect of the evaporator of the ceiling machine in the prior art.

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

[0006] The invention discloses a ceiling machine, which comprises a chassis, an evaporator and a lifting device, one side of the lifting device is connected with the chassis, the other side is provided with a hanging piece capable of moving up and down, the hanging piece is used for mounting the evaporator, the lifting device drives the evaporator to move in the vertical direction through the hanging piece, and the lifting device comprises a locking piece, which is used for locking the hanging piece after the evaporator is lifted to an assembly position. Thus, in the normal installation state of the ceiling machine, when the evaporator needs to be cleaned, the locking piece is opened, the evaporator is driven by the lifting device to move downwards to the ground, and the cleaning personnel can directly clean the evaporator on the ground, so that the cleaning personnel can safely and carefully clean the evaporator on the ground, greatly reducing the operation difficulty of the evaporator cleaning, and effectively improving the cleaning effect of the evaporator. Meanwhile, after cleaning, the evaporator is driven upwards by the lifting device until the evaporator is lifted to the assembly position, and then the hanging piece is locked by the locking piece.

[0007] 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 bottom, the connecting plate and the slide rail piece at the bottom can relatively slide in the vertical direction, and the hook is used for mounting the evaporator.

Thus, the two adjacent slide rail pieces (and the slide rail piece and the hook) cannot be separated when being extended downwards, and the normal extension of the second lifting assembly is ensured.

[0011] Further, for any two adjacent slide rail pieces, the first limiting seat of the lower slide rail piece can abut against the side wall of the slide rail cavity of the upper slide rail piece; and the limiting piece can abut against the side wall of the slide rail cavity of the lowermost slide rail piece, which is beneficial to ensure that the two adjacent slide rail pieces (and the slide rail piece and the hook) can smoothly slide, and avoid unnecessary shaking of the second lifting assembly during the extension and contraction.

Thus, the two adjacent slide rail pieces (and the slide rail piece and the hook) cannot be separated when being retracted upwards, and the normal retraction of the second lifting assembly is ensured; at the same time, in combination with the common limiting of the second limiting seat and the limiting table, the two adjacent slide rail pieces (and the slide rail piece and the hook) can only slide within a small space in the vertical direction, and cannot be separated, which is beneficial to ensure the extension and contraction stability of the entire second lifting assembly.

[0013] Further, the upper end of the second lifting assembly is provided with a fixing seat, and the second lifting assembly is connected with the bottom disc through the fixing seat, so as to ensure the fixed connection between the second lifting assembly and the bottom disc.

[0014] Further, the second lifting assembly comprises a traction mechanism, a containing cavity is formed between the fixing seat and the chassis, the traction mechanism connected with the chassis is arranged in the containing cavity, a traction rope of the traction mechanism extends to the slide rail cavity of the slide rail piece and is connected with the connecting plate of the hook. Thus, by arranging the traction mechanism, on the one hand, the second lifting assembly can automatically lift and lower the evaporator, which greatly reduces the operation difficulty and operation risk of people when lifting and lowering the evaporator, and on the other hand, the telescopic form of the second lifting assembly is combined with the traction mechanism, so that the evaporator can be lowered more stably and will not shake, and double insurance is provided for preventing the evaporator from falling accidentally.

Detailed Implementation

[0032] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to communicate the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this invention can be combined with each other. The directional terms used in this application, such as "upper" and "lower," are based on the normal assembly state of the ceiling machine; or, more intuitively, the ceiling is above and the ground is below.

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

[0035] In existing ceiling cleaning systems, some users often require regular cleaning of internal components (such as the impeller and evaporator). However, ceiling cleaning systems are typically installed on the ceiling. One method for cleaning these internal components is to remove the entire unit from the ceiling and then remove the internal parts for cleaning (or directly remove the parts from the installed unit). This method is time-consuming and laborious, and carries the risk of the entire unit or parts falling. Another method is to insert a water hose into the ceiling cleaning system for rinsing. This method requires cleaning personnel to operate from a height, often facing the risk of water spillage and falls, making the cleaning operation difficult. Furthermore, the obstruction caused by the internal components can create dead zones in the cleaning process, resulting in poor cleaning effectiveness.

[0036] Example 1

[0037] Taking the fan wheel 3 of the ceiling-mounted air conditioner as an example, in the existing technology, cleaning the fan wheel of a ceiling-mounted air conditioner under normal installation conditions is often difficult, and there is even a risk of the fan wheel falling off. To solve this problem in the existing technology, this embodiment proposes a ceiling-mounted air conditioner, as shown in the attached figure. Figures 1-11 As shown, the ceiling machine includes a chassis 1, a fan 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 outer edge of the fan wheel 3 is provided with a mounting part 31. The hanging part is detachably connected to the mounting part 31. The lifting device 5 drives the fan wheel 3 to move in the vertical direction through the hanging part.

[0038] Thus, in the normal installation state of the ceiling machine, when the wind wheel 3 needs to be disassembled and cleaned, the hanging piece is connected with the mounting part 31, then the wind wheel 3 is disassembled, and then the wind wheel 3 is driven by the lifting device 5 to move downward to the ground, so that the cleaning personnel can directly clean the wind wheel 3 on the ground. On the one hand, the wind wheel 3 does not need to be lifted during disassembly, and the falling of the wind wheel 3 is avoided. On the other hand, the cleaning personnel can safely and carefully clean the wind wheel 3 on the ground, greatly reducing the operation difficulty of the wind wheel cleaning, and effectively improving the cleaning effect of the wind wheel 3. At the same time, after cleaning is completed, the wind wheel 3 is driven upward by the lifting device 5, then the wind wheel 3 is assembled and fixed with the motor 2, and then the hanging piece is disassembled and separated from the mounting part 31.

[0039] For the use state of the ceiling machine, 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 are conventional technologies of the ceiling machine, which will not be described herein. The application focuses on the protection and cleaning operation of the wind wheel 3 during disassembly.

[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 a motor shaft of the first motor 62, the other end is connected with the support frame 64 in a rotatable manner, 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 has simple structure, stable and reliable 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, an installation plate 621 can be arranged on the related parts, and the installation plate 621 is connected with the bottom plate 1 by using fasteners to realize the fixed connection between the related parts and the bottom plate 1. In the drawings of the application, only the first motor 62 is provided with the installation plate 621. For other parts connected with the bottom plate 1 in the lifting device 5, the same can be done, which will not be described herein. The lifting hook 67 can be regarded as a hanging piece of the lifting device 5.

[0041] 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.

[0042] 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, the deceleration seat 662 is provided with a deceleration piece 663 on the side 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 relatively stably in the descending process, so as to avoid that the wind wheel 3 falls too fast, and in the case that the first motor 62 suddenly fails, the wind wheel 3 can also be prevented from falling rapidly due to the pulling of the flexible cable 65, and 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 continuing to fall. 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 deceleration piece 663 will be offset to a certain extent along with the rotation of the gear 661, so as to provide a certain deceleration effect on the rotation of the rotating shaft 61 and the gear 661, and correspondingly, a certain deceleration effect can be provided on the descending process and the ascending process of the wind wheel 3.

[0043] 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 direction of M, 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 direction of N, 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, so as to 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 relatively stably, and the falling speed of the wind wheel 3 is prevented from being too fast. At the same time, when the wind wheel 3 is in the ascending state, the resistance received 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.

[0044] 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.

[0045] 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.

[0046] Example 2

[0047] 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 air conditioner 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 equipped with a hanging component that can move up and down. The hanging component supports the evaporator 4. The lifting device 5 moves the evaporator 4 vertically 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 is raised to the assembly position, so as to achieve a stable assembly of the evaporator 4. The assembly position of the evaporator 4 refers to the conventional installation position of the evaporator 4 under normal installation and use conditions of the ceiling-mounted air conditioner, or it can be understood as the conventional evaporator assembly position in a conventional ceiling-mounted air conditioner.

[0048] 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.

[0049] 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.

[0050] The lifting device 5 includes a second lifting assembly 7, the second lifting assembly 7 includes a plurality of slide rail pieces 71 connected in sequence from top to bottom, and any two adjacent slide rail pieces 71 can slide relative to each other in the vertical direction. 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, and the hook 73 can also drive the evaporator 4 to rise or fall. The hook 73 can be regarded as a hanging piece of the lifting device 5.

[0051] The slide rail piece 71 and the connecting plate 731 are provided with locking holes 72. With the sliding of any two adjacent slide rail pieces 71, the locking holes 72 of any two adjacent slide rail pieces 71 can be aligned. With the sliding of the connecting plate 731 and the slide rail piece 71, the locking holes 72 of the connecting plate 731 and the slide rail piece 71 can be aligned. 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 lifted or lowered to a certain height.

[0052] For the sliding between the slide rail pieces 71, the slide rail piece 71 has a slide rail cavity 711. 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

[0053] ​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.

[0054] 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 smoothly slide, and avoid unnecessary shaking of the second lifting assembly 7 during the stretching and contraction process. 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.

[0055] 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 contracted upwards, and the normal contraction of the second lifting assembly 7 is ensured; at the same time, the combined limiting of the second limiting seat 714 and the limiting table 712 enables the two adjacent slide rail pieces 71 to slide only within a small space in the vertical direction, and the two slide rail pieces will not be separated, which is beneficial to ensure the stability of the stretching and contraction 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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 second lifting assembly 7 is combined with the traction mechanism 742, so that the evaporator 4 can be lowered more stably, without shaking, and also provides "double insurance" 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, the traction rope 741 can be wound on the rope roller 7421.

[0060] In this embodiment, the ceiling machine is provided with at least three second lifting assemblies 7, which simultaneously hang and lift the evaporator 4, to ensure that the evaporator 4 can be lifted more stably, and the force on the evaporator 4 is stable during lifting, without rolling over or turning over.

[0061] Embodiment 3

[0062] In this embodiment, the first lifting assembly 6 in embodiment 1 is replaced by the second lifting assembly 7 in embodiment 2. At the same time, this embodiment maintains the related 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.

[0063] 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; or the second lifting assembly 7 can be rotatably connected with the chassis 1 (or the hook 73 itself can rotate 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.

[0064] 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.

[0065] Embodiment 4

[0066] 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 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 there is some repetition in the related content, this embodiment will not be described in detail.

[0067] 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.

[0068] 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.

[0069] In the present application, for any ceiling machine, on the basis of the related structure and assembly relationship provided in the present application, the ceiling machine also includes conventional components of indoor units such as a shell, a water pan, and a wind guide ring; similarly, the ceiling machine also includes an outdoor unit and related components; since these conventional components are prior art, they will not be described in detail here.

[0070] 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 principles of the present application should be included in the protection scope of the present application.
