Technical Field

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

[0002] At present, with the improvement of living standards, people have higher and higher requirements for the functionality of air conditioners. Among them, ceiling air conditioners are highly sought after by users because they are embedded in the ceiling and do not occupy indoor space. However, due to structural limitations, current ceiling air conditioners need to disassemble the electric control box cover, electric control box and wiring in turn before disassembling the air guide ring and maintaining or replacing the wind wheel or other parts inside the air guide ring. This requires many parts to be disassembled, high operating risks, difficult maintenance, time-consuming and labor-intensive, high labor and time costs, and poor user experience. Summary of the invention

[0004] To solve the above problems, the technical solution of the present invention is achieved as follows:

[0005] The present invention provides a ceiling machine, including a shell, a water receiving tray, an electric control box and an air guide ring, the water receiving tray is connected to the shell, the water receiving tray is provided with an air inlet, the air guide ring cover is provided outside the air inlet, the electric control box is installed on the water receiving tray, a stop groove is formed between the electric control box and the water receiving tray, the air guide ring is provided with an extension strip, the extension strip cooperates with the stop groove, the water receiving tray is provided with a buckle, the air guide ring is provided with a clamping hole, and the buckle is clamped with the clamping hole. Compared with the prior art, the ceiling machine provided by the present invention uses an extension strip that cooperates with the stop groove and a clamping hole that clamps with the buckle, so it can simplify the disassembly and assembly structure, reduce the number of parts that need to be disassembled during maintenance, reduce the operation risk and maintenance difficulty, save labor costs and time costs, and improve user experience.

[0006] Furthermore, the clamping hole includes a first hole section and a second hole section which are arranged along a preset direction and are interconnected, the width of the first hole section is greater than the width of the second hole section, the first hole section is used for the buckle to pass through, and the second hole section is used for matching with the buckle after the air guide ring slides a preset distance relative to the water receiving tray along a preset direction. This can ensure the reliability of the assembly of the buckle and the clamping hole, and facilitate installation or disassembly, which is convenient and practical.

[0007] Further, the difference between the width of the first hole segment and the width of the buckle is in the range of 4 mm to 6 mm; and / or, the difference between the width of the second hole segment and the width of the buckle is in the range of 1 mm to 2 mm. A reasonable difference between the width of the first hole segment and the width of the buckle can ensure the rough positioning effect of the first hole segment on the buckle while facilitating the buckle to pass through the first hole segment. A reasonable difference between the width of the second hole segment and the width of the buckle can ensure the matching accuracy of the buckle and the second hole segment, and fix the relative position of the air guide ring and the water receiving tray.

[0008] Furthermore, the buckle includes a connecting portion and a clamping portion connected to each other, the connecting portion is connected to the water receiving tray, the clamping portion is arranged perpendicular to the connecting portion, and the clamping portion is used to pass through the clamping hole to clamp the air guide ring between the clamping portion and the water receiving tray, thereby fixing the relative position of the air guide ring and the water receiving tray to prevent the air guide ring from being separated from the water receiving tray.

[0009] Furthermore, the length of the clamping portion ranges from 7 mm to 15 mm. A reasonable length of the clamping portion can save materials and reduce production costs while ensuring the clamping and limiting effect on the air guide ring.

[0010] Furthermore, the width direction of the extension strip is the same as the length direction of the clamping portion, and the ratio of the width of the extension strip to the length of the clamping portion is in the range of 0.8 to 1.5.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Please refer to Figures 1 to 3 The embodiment of the present invention provides a ceiling machine 100 for controlling indoor temperature. It can simplify the assembly and disassembly structure, reduce the number of parts that need to be disassembled during maintenance, reduce operation risks and maintenance difficulties, save labor costs and time costs, and improve user experience.

[0034] It should be noted that the ceiling machine 100 is installed on the indoor ceiling, the middle part of its bottom surface is used for air intake, and the surrounding parts of the bottom surface are used for air outlet. The ceiling machine 100 can exchange heat during the air flow, so that the airflow blown out from the surrounding parts of the bottom surface of the ceiling machine 100 can achieve the function of heating or cooling, thereby adjusting the indoor temperature. Specifically, in the process of maintaining the ceiling machine 100, it is generally necessary to first use a ladder to climb to the height of the ceiling machine 100, and then disassemble the shielding parts on the bottom surface of the ceiling machine 100 before maintaining or replacing the parts inside the ceiling machine 100.

[0035] The ceiling machine 100 includes a housing 110, a water tray 120, an electric control box 130, an air guide ring 140, a driving motor 150 and a wind wheel 160. The water tray 120 is connected to the housing 110, and the water tray 120 is provided with an air inlet 121, which is used for air to flow into the ceiling machine 100 to realize the air intake function of the ceiling machine 100, and the air guide ring 140 is covered outside the air inlet 121, and the air guide ring 140 is used to guide the air intake airflow to improve the air intake efficiency. Specifically, the shell 110 is embedded in the indoor ceiling, the water tray 120 is arranged at the bottom of the shell 110, and the water tray 120 and the air guide ring 140 are both located on the bottom surface of the ceiling machine 100. During the maintenance of the ceiling machine 100, it is necessary to remove the air guide ring 140 from the water tray 120 to open the air inlet 121, so that the staff can maintain or replace the parts in the ceiling machine 100 through the air inlet 121.

[0036] Further, the electric control box 130 is mounted on the water receiving tray 120, a stop groove 170 is formed between the electric control box 130 and the water receiving tray 120, and the air guide ring 140 is provided with an extension strip 141, and the extension strip 141 cooperates with the stop groove 170, and the stop groove 170 can limit the extension strip 141, thereby limiting the entire air guide ring 140, and then fixing the relative position of the air guide ring 140, the electric control box 130 and the water receiving tray 120. The water receiving tray 120 is provided with a buckle 122, and the air guide ring 140 is provided with a clamping hole 142, and the buckle 122 is clamped with the clamping hole 142 to fix the relative position of the air guide ring 140 and the water receiving tray 120, and prevent the air guide ring 140 from being separated from the water receiving tray 120. Accordingly, in the process of maintaining the ceiling machine 100, it is only necessary to release the clamping state between the buckle 122 and the clamping hole 142 and pull the extension strip 141 out of the stop groove 170 to realize the removal of the air guide ring 140, which is convenient and quick. In this way, the disassembly and assembly structure of the air guide ring 140 is simplified, and the air guide ring 140 can be removed without removing the electric control box 130, reducing the number of parts that need to be removed during maintenance, reducing the operation risk and maintenance difficulty, saving labor costs and time costs, and improving user experience.

[0037] It should be noted that the driving motor 150 is installed in the housing 110 and is detachably connected to the wind wheel 160 through an output shaft 151. The driving motor 150 is used to drive the wind wheel 160 to rotate through the output shaft 151 to achieve the air outlet function of the ceiling machine 100. The position of the wind wheel 160 corresponds to the position of the air inlet 121. After the air guide ring 140 is disassembled, the staff can remove the wind wheel 160 through the air inlet 121 to facilitate maintenance or replacement of the wind wheel 160. Specifically, the minimum spacing between the projection of the wind wheel 160 on the plane where the water tray 120 is located and the side wall of the air inlet 121 is greater than or equal to 10 mm, and the spacing between the wind wheel 160 and the plane where the water tray 120 is located is greater than or equal to 30 mm, so that the wind wheel 160 can be removed from the air inlet 121.

[0038] Please refer to Figures 4 to 8 The clamping hole 142 includes a first hole section 1421 and a second hole section 1422. The first hole section 1421 and the second hole section 1422 are arranged along a preset direction and are interconnected. The width of the first hole section 1421 is greater than the width of the second hole section 1422. The first hole section 1421 is used for the buckle 122 to pass through, so as to facilitate the buckle 122 to be installed in the clamping hole 142. The second hole section 1422 is used to cooperate with the buckle 122 after the air guide ring 140 slides a preset distance relative to the water receiving tray 120 along a preset direction, that is, the buckle 122 and the clamping hole 142 have a stroke for clamping. After the buckle 122 passes through the first hole section 1421, the air guide ring 140 needs to be moved along the preset direction by the stroke to complete the clamping of the buckle 122 and the second hole section 1422. Accordingly, when releasing the engagement state between the buckle 122 and the locking hole 142, the air guide ring 140 needs to be slid in the opposite direction by a preset distance to make the buckle 122 disengage from the second hole section 1422, and then the air guide ring 140 is removed from the water receiving tray 120. During this process, the buckle 122 passes through the first hole section 1421, and the buckle 122 does not interfere with the removal of the air guide ring 140. In this way, since the width of the first hole section 1421 is large and the width of the second hole section 1422 is small, the reliability of the assembly of the buckle 122 and the locking hole 142 can be guaranteed, and the installation or removal can be facilitated, which is convenient and practical.

[0039] Furthermore, the difference between the width of the first hole segment 1421 and the width of the buckle 122 ranges from 4 mm to 6 mm, that is, the single-sided gap between the buckle 122 and the first hole segment 1421 (the gap between the buckle 122 and any side wall of the first hole segment 1421 perpendicular to the preset direction) ranges from 2 mm to 3 mm, so as to achieve the rough positioning of the buckle 122 by the first hole segment 1421. A reasonable difference between the width of the first hole segment 1421 and the width of the buckle 122 can ensure the rough positioning effect of the first hole segment 1421 on the buckle 122 while facilitating the buckle 122 to pass through the first hole segment 1421.

[0040] The difference between the width of the second hole section 1422 and the width of the buckle 122 ranges from 1 mm to 2 mm, that is, the single-sided gap between the buckle 122 and the second hole section 1422 (the gap between the buckle 122 and any side wall of the second hole section 1422 perpendicular to the preset direction) ranges from 0.5 mm to 1 mm, so as to achieve reliable fit between the second hole section 1422 and the buckle 122. A reasonable difference between the width of the second hole section 1422 and the width of the buckle 122 can ensure the fit accuracy between the buckle 122 and the second hole section 1422, and reliably fix the relative position of the air guide ring 140 and the water receiving tray 120.

[0041] In this embodiment, the difference between the width of the first hole segment 1421 and the width of the buckle 122 is in the range of 4 mm to 6 mm, and the difference between the width of the second hole segment 1422 and the width of the buckle 122 is in the range of 1 mm to 2 mm. However, this is not limited to this. In other embodiments, only the difference between the width of the first hole segment 1421 and the width of the buckle 122 is limited to the range of 4 mm to 6 mm, or only the difference between the width of the second hole segment 1422 and the width of the buckle 122 is limited to the range of 1 mm to 2 mm.

[0042] It is worth noting that the distance between the side wall of the hole 142 and the edge of the air guide ring 140 ranges from 2 mm to 6 mm, so as to ensure the strength of the hole 142, thereby ensuring the reliability of the fit between the hole 142 and the buckle 122, and avoiding the edge of the air guide ring 140 from warping.

[0043] The buckle 122 includes a connecting portion 1221 and a clamping portion 1222 that are connected to each other. The connecting portion 1221 is connected to the water receiving tray 120, and the clamping portion 1222 is arranged perpendicular to the connecting portion 1221. The clamping portion 1222 is used to pass through the clamping hole 142 to clamp the air guide ring 140 between the clamping portion 1222 and the water receiving tray 120, thereby fixing the relative position of the air guide ring 140 and the water receiving tray 120 to prevent the air guide ring 140 from being separated from the water receiving tray 120. Specifically, during the assembly process of the buckle 122 and the clamping hole 142, the air guide ring 140 is first moved to fit with the water receiving tray 120 so that the clamping portion 1222 passes through the first hole section 1421 of the clamping hole 142, and then the air guide ring 140 is slid a preset distance along a preset direction relative to the water receiving tray 120 so that the clamping portion 1222 cooperates with the second hole section 1422 of the clamping hole 142. At this time, the air guide ring 140 is clamped between the clamping portion 1222 and the water receiving tray 120 to complete the assembly.

[0044] Furthermore, the length direction of the clamping portion 1222 is the preset direction, and the length range of the clamping portion 1222 is 7 mm to 15 mm. A reasonable length of the clamping portion 1222 can save materials and reduce production costs while ensuring the clamping and limiting effect on the air guide ring 140.

[0045] It should be noted that when the buckle 122 is assembled with the clamping hole 142, and the air guide ring 140 slides a preset distance along a preset direction relative to the water receiving tray 120, the extension strip 141 of the air guide ring 140 simultaneously extends into the stop groove 170 along the preset direction and cooperates with the stop groove 170. Specifically, the width direction of the extension strip 141 is the same as the length direction of the clamping portion 1222, that is, the width direction of the extension strip 141 is the same as the preset direction, and the ratio of the width of the extension strip 141 to the length of the clamping portion 1222 ranges from 0.8 to 1.5. A reasonable ratio of the width of the extension strip 141 to the length of the clamping portion 1222 can ensure the reliability of the cooperation between the extension strip 141 and the stop groove 170, and prevent the extension strip 141 from accidentally falling out of the stop groove 170.

[0046] In this embodiment, the number of the buckles 122 and the number of the holes 142 are both four, and each buckle 122 is engaged with a hole 142, wherein the four holes 142 are divided into two groups, and the two groups of holes 142 are relatively arranged at the two ends of the air guide ring 140, and the four buckles 122 and the four holes 142 work together to improve the reliability of the connection between the air guide ring 140 and the water receiving tray 120, and prevent the air guide ring 140 from accidentally detaching from the water receiving tray 120.

[0047] In this embodiment, the air guide ring 140 is provided with a through hole 143, and the through hole 143 and the extension strip 141 are relatively arranged at the two ends of the air guide ring 140, and the water receiving tray 120 is provided with a threaded hole 123, and the threaded hole 123 is used to cooperate with the screw passing through the through hole 143 to further fix the relative position of the air guide ring 140 and the water receiving tray 120, so as to prevent the air guide ring 140 from being separated from the water receiving tray 120. Specifically, the through hole 143 and the extension strip 141 are relatively arranged at the left and right ends of the air guide ring 140, and the two groups of clamping holes 142 are relatively arranged at the front and rear ends of the air guide ring 140. The through hole 143, the extension strip 141 and the two groups of clamping holes 142 work together to realize the multi-directional simultaneous positioning of the air guide ring 140, and ensure the reliability of the assembly of the air guide ring 140.

[0048] It is worth noting that the water tray 120 is provided with a limiting groove 124, the air inlet 121 is provided on the bottom wall of the limiting groove 124, the buckle 122 is provided on the bottom wall of the limiting groove 124, the air guide ring 140 is provided in the limiting groove 124, and the limiting groove 124 is used to limit the air guide ring 140 to prevent the air guide ring 140 from being displaced relative to the water tray 120 under the action of vibration when the ceiling machine 100 is running. Specifically, the air guide ring 140 is arranged to fit the bottom wall of the limiting groove 124, and the minimum spacing between the air guide ring 140 and the side wall of the limiting groove 124 ranges from 1 mm to 2 mm. A reasonable spacing between the air guide ring 140 and the side wall of the limiting groove 124 can ensure sealing, prevent air from entering the ceiling machine 100 from the gap between the air guide ring 140 and the water tray 120, and facilitate disassembly and assembly.

[0049] Furthermore, an end wall 147 is provided on one side of the air guide ring 140 away from the extension strip 141, and the end wall includes a first wall body 1471, a second wall body 1472 and a third wall body 1473 connected in sequence. The position of the first wall body 1471 corresponds to the position of one group of buckles 122, and the third wall body 1473 corresponds to the position of another group of buckles 122. Specifically, there is a first gap between the first wall body 1471 and the side wall of the limiting groove 124, and the difference between the first gap and the length of the clamping portion 1222 is greater than or equal to 2 mm. A reasonable first gap can ensure that the buckle 122 corresponding to the position of the first wall body 1471 can smoothly complete the stroke (slide the preset distance) along the preset direction, thereby realizing the cooperation between the buckle 122 and the clamping hole 142; there is a second gap between the third wall body 1473 and the side wall of the limiting groove 124, and the second gap is equal to the first gap. The difference between the second gap and the length of the clamping portion 1222 is greater than or equal to 2 mm. A reasonable second gap can ensure that the buckle 122 corresponding to the position of the third wall body 1473 can smoothly complete the stroke (slide the preset distance) along the preset direction, thereby realizing the cooperation between the buckle 122 and the clamping hole 142.

[0050] Specifically, the air guide ring 140 is elastic, and the side wall of the limiting groove 124 corresponding to the position of the second wall body 1472 is inclined. The inclined side wall of the limiting groove 124 can guide the air guide ring 140 during the disassembly process, so as to facilitate the disassembly of the air guide ring 140. During the assembly process of the air guide ring 140 and the water receiving tray 120, the air guide ring 140 undergoes elastic deformation, wherein the first wall body 1471 and the third wall body 1473 both slide in the limiting groove 124, and the second wall body 1472 slides into the limiting groove 124 under the guidance of the inclined side wall of the limiting groove 124, until the buckle 122 is engaged with the clamping hole 142, at which time the minimum spacing is formed between the second wall body 1472 and the side wall of the limiting groove 124.

[0051] In this embodiment, the air guide ring 140 is provided with a pull portion 144, and the water receiving tray 120 is provided with a clearance groove 125. The pull portion 144 covers part of the clearance groove 125. The clearance groove 125 is used for the staff to insert their fingers into it, so that they can apply force to the pull portion 144, and pull the entire air guide ring 140 away from the water receiving tray 120 through the pull portion 144, so that the air guide ring 140 is partially separated from the limit groove 124. Then the staff can pull the entire air guide ring 140 outward through the pull portion 144, so that the buckle 122 and the clamping hole 142 are released from the clamping state, and the extension strip 141 is separated from the stop groove 170, so as to realize the removal of the air guide ring 140. Specifically, the depth of the clearance groove 125 is greater than or equal to 5 mm, and the width of the pull portion 144 is greater than or equal to 25 mm, so that the staff can insert their fingers into the clearance groove 125 and apply force to the pull portion 144.

[0052] Furthermore, the air guide ring 140 is also provided with two side edges 148, the end wall 147 and the extension strip 141 are both provided between the two side edges 148, and there are two pull parts 144, each of which is provided close to one side edge 148. Specifically, the spacing between the pull part 144 and the side edge 148 ranges from 30 mm to 60 mm, and a reasonable spacing between the pull part 144 and the side edge 148 can ensure the strength of the pull part 144 and facilitate the application of force to remove the entire air guide ring 140.

[0053] In this embodiment, the air guide ring 140 is arranged to extend into the wind wheel 160, that is, the bottom surface of the air guide ring 140 is lower than the top surface of the wind wheel 160, and there is a third gap between the air guide ring 140 and the wind wheel 160 on the plane where the water receiving tray 120 is located. The difference between the length of the third gap and the length of the clamping portion 1222 is greater than or equal to 3 mm. A reasonable third gap can ensure that the wind wheel 160 will not cause obstruction to the air guide ring 140 during the disassembly process, which facilitates the disassembly of the air guide ring 140. However, it is not limited to this. In other embodiments, the air guide ring 140 may not extend into the wind wheel 160, that is, the bottom surface of the air guide ring 140 is higher than the top surface of the wind wheel 160. At this time, the air guide ring 140 and the wind wheel 160 are not on the same plane, and there is no third gap. It is also possible to ensure that the wind wheel 160 will not cause obstruction to the air guide ring 140 during the disassembly process without limiting the third gap.

[0054] The air guide ring 140 includes a ring body 145 and a protective net 146. The protective net 146 is connected to the middle of the ring body 145, and the extension strip 141 and the clamping hole 142 are both arranged on the ring body 145. The position of the protective net 146 corresponds to the position of the air inlet 121. The protective net 146 is used to guide the airflow, and the protective net 146 is also used to prevent foreign objects from accidentally extending into the air inlet 121. Specifically, the thickness of the protective net 146 ranges from 2 mm to 3 mm. A reasonable thickness of the protective net 146 can reduce noise and increase the air intake while ensuring strength.

[0055] In this embodiment, the ring body 145 and the protective net 146 are integrally formed to improve the connection strength, but it is not limited to this. In other embodiments, the ring body 145 can also be set separately from the protective net 146, and can be detachably connected by screws or snaps, and the connection method between the ring body 145 and the protective net 146 is not specifically limited.

[0056] In this embodiment, the protective net 146 is arranged in a circular shape, and a plurality of ribs 1461 are arranged radially and circumferentially along the inner edge of the circle. The spacing between two adjacent radial ribs 1461 ranges from 7 mm to 10 mm. The spacing between two adjacent radial ribs 1461 is proportional to the air intake volume. A reasonable spacing between two adjacent radial ribs 1461 can prevent foreign objects from accidentally extending into the air inlet 121 while maximizing the air intake volume.

[0057] In this embodiment, the protective net 146 is protruding from the ring body 145, and the distance between the plane where the protective net 146 is located and the plane where the ring body 145 is located is in the range of 10 mm to 16 mm. The distance between the plane where the protective net 146 is located and the plane where the ring body 145 is located is proportional to the air intake. A reasonable distance between the plane where the protective net 146 is located and the plane where the ring body 145 is located can increase the air intake as much as possible under the size limitation of the ceiling machine 100.

[0058] In addition, in order to demonstrate the beneficial effects of the present invention, the inventors conducted multiple comparative experiments, and the experimental results are shown in the following table:

[0059] Material thickness / mm Rib spacing / mm Protection net height / mm <![CDATA[Air intake volume / m 3 / h]]> Noise / dB 1.5 8 8 1968 52 2.0 8 8 1965 51 2.5 8 8 1960 50.3 3.0 8 8 1955 50.2 2.5 5 8 1770 52 2.5 6 8 1800 51.8 2.5 7 8 1920 51 2.5 8 8 1960 50.3 2.5 9 8 1965 50.1 2.5 10 8 1970 50 2.5 8 10 2000 50.3 2.5 8 12 2030 50 2.5 8 14 2070 49.5 2.5 8 16 2090 49.3

[0060] It can be seen from the above table that if the thickness of the protective net 146 is too small (the material thickness is 1.5 mm), it will directly affect the strength of the protective net 146, so that the protective net 146 will produce resonance sound when the ceiling machine 100 is running, resulting in increased noise. Therefore, the thickness of the protective net 146 is preferably 2 mm to 3 mm. If the distance between two adjacent radial ribs 1461 is too small (the distance between the ribs 1461 is 5 mm or 6 mm), the air intake will be greatly reduced, which will directly affect the effect of the ceiling machine 100. Therefore, the distance between two adjacent radial ribs 1461 is preferably 7 mm to 10 mm. If the distance between the plane where the protective net 146 is located and the plane where the ring body 145 is located is too small (the height of the protective net 146 is 8 mm), the air intake will be greatly reduced, which will directly affect the effect of the ceiling machine 100. Therefore, the distance between the plane where the protective net 146 is located and the plane where the ring body 145 is located is preferably 10 mm to 16 mm.

[0061] Please refer to Figure 5 , Figure 6 , Figures 9 to 13 For ease of understanding, the minimum distance between the projection of the wind wheel 160 on the plane where the water receiving tray 120 is located and the side wall of the air inlet 121 is represented as A, the distance between the wind wheel 160 and the plane where the water receiving tray 120 is located is represented as B, the width of the first hole section 1421 is represented as C, the width of the second hole section 1422 is represented as D, the width of the buckle 122 is represented as E, the distance between the side wall of the clamping hole 142 and the edge of the air guide ring 140 is represented as F, the length of the clamping portion 1222 is represented as G, and the length of the extension strip 141 is represented as The width is represented as H, the distance between the air guide ring 140 and the side wall of the limiting groove 124 is represented as J, the width of the pull part 144 is represented as L, the thickness of the protective net 146 is represented as M, the distance between two adjacent radial ribs 1461 is represented as N, the distance between the plane where the protective net 146 is located and the plane where the ring body 145 is located is represented as P, the first gap is represented as Q, the depth of the give way groove 125 is represented as R, the distance between the pull part 144 and the side 148 is represented as S, and the third gap is represented as T.

[0062] It is worth noting that during the disassembly of the air guide ring 140, the screws are first removed from the threaded holes 123 of the water receiving tray 120 and the through holes 143 of the air guide ring 140; then, a finger is inserted into the clearance groove 125, and the entire air guide ring 140 is pulled outward by the pulling part 144, so that the air guide ring 140 is separated from the water receiving tray 120. During this process, the air guide ring 140 is slightly tilted relative to the water receiving tray 120 to facilitate its escape from the limiting groove 124, and the clamping hole 142 moves relative to the buckle 122 until the buckle 122 escapes from the clamping hole 142, and at the same time, the extension strip 141 moves relative to the stop groove 170 until the extension strip 141 shrinks out of the stop groove 170; in this way, the air guide ring 140 can be disassembled in only two steps, the disassembly steps are simple, and the electric control box 130 has no connection with the air guide ring 140, the electric control box 130 only serves to limit the air guide ring 140, the air guide ring 140 can be disassembled without disassembling the electric control box 130, the number of parts that need to be disassembled is small, the operation risk and maintenance difficulty are low, time and labor are saved, and the ceiling machine 100 is easy to maintain.

[0063] Furthermore, during the disassembly of the wind wheel 160, the wind wheel 160 is first lifted in a direction perpendicular to the plane where the water receiving tray 120 is located, toward the direction close to the water receiving tray 120, so that the wind wheel 160 is suspended in the air and separated from the output shaft 151 of the drive motor 150; then the wind wheel 160 is translated for a distance in the direction of the side wall close to the air inlet 121 (the distance between the side wall and the projection of the wind wheel 160 on the plane where the water receiving tray 120 is located is the largest) to avoid interference with other components when the wind wheel 160 is tilted laterally; then the wind wheel 160 is taken out outward at an angle to allow the wind wheel 160 to escape from the air inlet 121, thereby completing the disassembly of the wind wheel 160 in a convenient and quick manner.

[0064] In the ceiling machine 100 described in the embodiment of the present invention, the water receiving tray 120 is connected to the housing 110, the water receiving tray 120 is provided with an air inlet 121, the air guide ring 140 is covered outside the air inlet 121, the electric control box 130 is installed on the water receiving tray 120, a stop groove 170 is formed between the electric control box 130 and the water receiving tray 120, the air guide ring 140 is provided with an extension strip 141, the extension strip 141 cooperates with the stop groove 170, the water receiving tray 120 is provided with a buckle 122, the air guide ring 140 is provided with a clamping hole 142, and the buckle 122 is clamped with the clamping hole 142.
