However, due to the limitations of the external dimensions of current ceiling air conditioners, the gap between the internal impeller and the water tray is small, resulting in a small movable space for the impeller during disassembly, and it cannot be removed from the air inlet on the water tray. As a result, during after-sales maintenance, if the impeller is to be maintained or replaced, the electric control box cover, electric control box, wiring, air guide ring and water tray need to be completely removed in turn. There are many parts to be disassembled, and the disassembly is difficult, time-consuming and labor-intensive, and the user experience is poor. Summary of the invention

DETAILED DESCRIPTION

[0028] 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.

[0029] First embodiment

[0030] Please refer to Figures 1 to 4 The embodiment of the present invention provides a wind wheel 100 for realizing the wind outlet function. The wind wheel 100 can be conveniently and quickly disassembled and assembled, the number of disassembled and assembled parts can be reduced, the difficulty of disassembly and assembly can be reduced, maintenance can be facilitated, time and labor can be saved, and user experience can be improved.

[0031] It should be noted that the wind wheel 100 is applied to the ceiling machine 10, which is installed on the indoor ceiling. The middle part of the bottom surface is used for air intake, and the surrounding parts of the bottom surface are used for air outlet. The ceiling machine 10 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 10 can achieve the function of heating or cooling, thereby adjusting the indoor temperature. Specifically, in the process of maintaining the ceiling machine 10, it is generally necessary to first use a ladder to climb to the height of the ceiling machine 10, and then disassemble the shielding parts on the bottom surface of the ceiling machine 10 before maintaining or replacing the wind wheel 100.

[0032] Furthermore, the ceiling machine 10 includes a housing 200, a water tray 300, an electric control box assembly 400, an air guide ring 500 and a driving motor 600. The housing 200 is embedded in the indoor ceiling, the water tray 300 is connected to the housing 200 and is arranged at the bottom of the housing 200, the water tray 300 is provided with an air inlet 310, the air inlet 310 is used for air to flow into the ceiling machine 10, so as to realize the air intake function of the ceiling machine 10, the air guide ring 500 is covered outside the air inlet 310, and the air guide ring 500 is used to guide the air intake airflow to improve the air intake efficiency. The electric control box assembly 400 is installed on the water tray 300, and the electric control box assembly 400 is used to realize the control function of the ceiling machine 10. The driving motor 600 is installed in the housing 200 and is detachably connected to the wind wheel 100 through an output shaft 610. The driving motor 600 is used to drive the wind wheel 100 to rotate through the output shaft 610 to achieve the air outlet function of the ceiling machine 10. Specifically, due to the size of the ceiling machine 10, after installation, the gap between the wind wheel 100 and the plane where the water tray 300 is located is less than 30 mm, resulting in a small movable space for the wind wheel 100 during the disassembly process, and it cannot be directly disassembled from the air inlet 310 of the water tray 300.

[0033] In the prior art, when the wind wheel 100 is to be maintained or replaced, it is necessary to remove the electric control box assembly 400 and the air guide ring 500 from the water receiving tray 300 in turn, and then remove the water receiving tray 300 from the outer casing 200, so that the wind wheel 100 can be removed from the output shaft 610 of the drive motor 600, thereby maintaining or replacing the wind wheel 100. In the present application, the wind wheel 100 is made into a split detachable structure, so that the size of two or more individual parts in the wind wheel 100 is reduced relative to the total size of the wind wheel 100. In this way, when the wind wheel 100 is maintained or replaced, there is no need to remove the electric control box assembly 400 and the water receiving tray 300. It is only necessary to remove the air guide ring 500 from the water receiving tray 300 to open the air inlet 310, and then remove the two or more individual parts in the wind wheel 100 from the air inlet 310 in turn, and separate them from the output shaft 610 of the drive motor 600. In this process, since the size of the individual parts is small, they can be easily taken out from the air inlet 310, which is convenient and quick.

[0034] The wind wheel 100 includes a wind wheel body 110 and a connecting member 120. A bearing platform 111 is provided in the middle of the wind wheel body 110, and the connecting member 120 is covered outside the bearing platform 111 and is detachably connected to the bearing platform 111. The bearing platform 111 is used to support and limit the connecting member 120. An avoidance cavity 112 is provided in the bearing platform 111, and the avoidance cavity 112 is used for the output shaft 610 of the driving motor 600 to pass through, so that the output shaft 610 is connected to the connecting member 120. Specifically, the wind wheel body 110 and the connecting member 120 are separately provided and are two single parts of the wind wheel 100. After the wind wheel body 110 and the connecting member 120 are assembled, the wind wheel 100 is formed, wherein the connecting member 120 is used to be detachably connected to the output shaft 610 of the driving motor 600, so as to drive the wind wheel body 110 to rotate under the action of the driving motor 600, and the wind wheel body 110 is used to generate negative pressure during the rotation process to drive the air flow, thereby realizing the air outlet function of the ceiling machine 10. Since the sizes of the wind wheel body 110 and the connecting member 120 are both smaller than the total size of the wind wheel 100, the connecting member 120 and the wind wheel body 110 can be removed from the air inlet 310 in turn without disassembling the electric control box assembly 400 and the water receiving tray 300. Therefore, the disassembly and assembly operation of the wind wheel 100 is conveniently and quickly realized, the number of disassembled parts is reduced, the difficulty of disassembly and assembly is reduced, maintenance is convenient, time and labor are saved, and user experience is improved.

[0035] It is worth noting that the axial direction of the wind wheel 100 is perpendicular to the plane where the water collecting tray 300 is located, the wind wheel body 110 and the connecting member 120 are spliced ​​in the axial direction of the wind wheel 100, and the heights of the wind wheel body 110 and the connecting member 120 in the axial direction of the wind wheel 100 are both smaller than the height of the wind wheel 100 in its axial direction. Among them, the cross-sectional size of the connecting member 120 is small, and it can be easily removed from the air inlet 310. After the connecting member 120 is removed, the gap between the wind wheel body 110 and the plane where the water collecting tray 300 is located increases, and the movable space of the wind wheel body 110 increases, so that the wind wheel body 110 can be removed from the air inlet 310 at an angle, which is convenient and quick. Specifically, during the disassembly of the wind wheel 100, the connecting member 120 is first removed from the wind wheel body 110, and the connecting member 120 and the output shaft 610 are disassembled at the same time; the connecting member 120 is then taken out from the air inlet 310; then the wind wheel body 110 is tiltedly taken out from the air inlet 310 to allow the output shaft 610 to retract to avoid the cavity 112, and the disassembly of the wind wheel 100 is completed. Thereafter, the connecting member 120 and / or the wind wheel body 110 can be maintained or replaced as needed to achieve maintenance operations on the wind wheel 100.

[0036] It should be noted that the supporting platform 111 is in the shape of a cone, and the shape of the connecting member 120 matches the shape of the supporting platform 111. The connecting member 120 and the supporting platform 111 are arranged in close contact to ensure the supporting and limiting effect of the supporting platform 111 on the connecting member 120. In addition, the cone-shaped supporting platform 111 and the connecting member 120 matching its shape can reduce wind resistance, avoid affecting the air intake volume, and reduce wind noise.

[0037] In this embodiment, an external thread 113 is provided on the outer side of the bearing platform 111, and an internal thread 121 is provided on the inner side of the connecting member 120. The external thread 113 cooperates with the internal thread 121 to fix the relative position of the bearing platform 111 and the connecting member 120, thereby fixing the relative position of the wind rotor body 110 and the connecting member 120, and preventing the wind rotor body 110 from being displaced relative to the connecting member 120. Specifically, during the disassembly process of the wind rotor 100, the connecting member 120 is twisted relative to the bearing platform 111 to loosen the internal thread 121 relative to the external thread 113, thereby removing the connecting member 120 from the bearing platform 111, and completing the detachment of the connecting member 120 from the wind rotor body 110.

[0038] Further, the thread height of the external thread 113 and the internal thread 121 ranges from 1.5 mm to 3 mm, and a reasonable thread height of the external thread 113 and the internal thread 121 can ensure the reliability of assembly and the efficiency of disassembly, and facilitate the maintenance of the wind wheel 100. The pitch of the external thread 113 and the internal thread 121 ranges from 6 mm to 10 mm, and a reasonable pitch of the external thread 113 and the internal thread 121 can ensure the reliability of assembly and the efficiency of disassembly, and facilitate the maintenance of the wind wheel 100.

[0039] In this embodiment, the thread height of the external thread 113 and the internal thread 121 ranges from 1.5 mm to 3 mm, and the pitch of the external thread 113 and the internal thread 121 ranges from 6 mm to 10 mm. However, this is not limited to this. In other embodiments, only the thread height of the external thread 113 and the internal thread 121 is limited to 1.5 mm to 3 mm, or only the pitch of the external thread 113 and the internal thread 121 is limited to 6 mm to 10 mm.

[0040] The wind wheel body 110 includes a fixing plate 114 and a plurality of blades 115. The plurality of blades 115 are distributed in a circular array and are all connected to the fixing plate 114. The plurality of blades 115 work together to drive air flow. In this embodiment, the fixing plate 114 and the plurality of blades 115 are integrally formed to improve the connection strength, ensure the overall strength of the wind wheel 100, and prevent the wind wheel 100 from deforming during operation. Specifically, the plurality of blades 115 together form an air induction cavity 116, the bearing platform 111 is disposed in the middle of the fixing plate 114, and protrudes toward the air induction cavity 116, the connecting member 120 extends into the air induction cavity 116 from a side of the air induction cavity 116 away from the fixing plate 114, and is detachably connected to the bearing platform 111 in the air induction cavity 116. During the disassembly of the wind wheel 100 , the worker can put his hand through the air inlet 310 and extend it into the air inlet cavity 116 to remove the connecting member 120 from the supporting platform 111 , which is convenient and quick.

[0041] The wind wheel 100 described in the embodiment of the present invention has a bearing platform 111 disposed in the middle of the wind wheel body 110, a connecting member 120 is covered outside the bearing platform 111 and is detachably connected to the bearing platform 111, and an escape cavity 112 is provided in the bearing platform 111, and the escape cavity 112 is used for the output shaft 610 of the driving motor 600 to pass through, so that the output shaft 610 is connected to the connecting member 120. Compared with the prior art, the wind wheel 100 provided by the present invention adopts a detachably connected bearing platform 111 and a connecting member 120 and an escape cavity 112 provided in the bearing platform 111, so that the wind wheel 100 can be disassembled and assembled conveniently and quickly, the number of disassembled parts is reduced, the difficulty of disassembly and assembly is reduced, maintenance is convenient, time and labor are saved, and user experience is improved.

[0042] Second embodiment

[0043] Please refer to Figures 5 to 8 The embodiment of the present invention provides a wind wheel 100. Compared with the first embodiment, the difference of this embodiment is that the detachable connection method between the connecting member 120 and the wind wheel body 110 is different.

[0044] In this embodiment, the connecting member 120 is no longer threadedly connected to the supporting platform 111 , but is snap-connected to the supporting platform 111 to achieve a detachable connection between the connecting member 120 and the wind wheel body 110 .

[0045] It is worth noting that the bearing platform 111 is provided with a slot 117, and the connecting member 120 is provided with a spring buckle 122, which is engaged with the slot 117 to fix the relative position of the bearing platform 111 and the connecting member 120, thereby fixing the relative position of the wind rotor body 110 and the connecting member 120, and preventing the wind rotor body 110 from being displaced relative to the connecting member 120. Specifically, the bearing platform 111 is provided with an assembly plane 118, which is arranged in an annular shape and parallel to the plane where the water receiving tray 300 is located, the slot 117 is provided on the assembly plane 118, the spring buckle 122 is arranged at the bottom of the connecting member 120, and the bottom of the connecting member 120 abuts against the assembly plane 118, so that the spring buckle 122 is engaged with the slot 117.

[0046] Furthermore, a clearance hole 119 is provided on the assembly plane 118 of the support platform 111. The clearance hole 119 and the slot 117 are spaced apart in a preset direction. The clearance hole 119 is used for the spring buckle 122 to pass through, and the slot 117 is used to cooperate with the spring buckle 122 after the connecting member 120 slides a preset distance relative to the support platform 111 along a preset direction, that is, the spring buckle 122 and the slot 117 are engaged with each other for a certain distance. After the spring buckle 122 passes through the clearance hole 119, the connecting member 120 needs to be rotated along the preset direction (the circumferential direction of the cone shape of the support platform 111) for this distance in order to complete the engagement of the spring buckle 122 with the slot 117. This can not only ensure the reliability of the assembly of the spring buckle 122 and the slot 117, but also facilitate installation or disassembly, which is convenient and practical. Correspondingly, when releasing the locking state between the spring buckle 122 and the slot 117, it is necessary to first rotate the connecting member 120 in the opposite direction by a preset distance so that the spring buckle 122 can be elastically deformed and disengaged from the slot 117, and the spring buckle 122 can move to a position corresponding to the clearance hole 119, and then the spring buckle 122 can be removed from the clearance hole 119, so that the connecting member 120 is completely separated from the supporting platform 111, thereby completing the detachment of the connecting member 120 from the wind wheel body 110.

[0047] The snap button 122 includes a connecting portion 123 and a snap button 124 that are connected to each other. The connecting portion 123 is connected to the connecting member 120, and the snap button 124 is arranged perpendicular to the connecting portion 123. The snap button 124 is used to pass through the clearance hole 119 and cooperate with the card slot 117 to fix the relative position of the bearing platform 111 and the connecting member 120, thereby fixing the relative position of the wind rotor body 110 and the connecting member 120 to prevent the connecting member 120 from being separated from the wind rotor body 110. Specifically, during the assembly process of the snap button 122 and the card slot 117, the connecting member 120 is first moved to fit with the assembly plane 118 of the bearing platform 111 so that the snap button 124 passes through the clearance hole 119, and then the connecting member 120 is rotated relative to the bearing platform 111 in a preset direction by a preset distance so that the snap button 124 cooperates with the card slot 117, and the assembly of the connecting member 120 and the bearing platform 111 is completed.

[0048] Furthermore, the length direction of the buckle portion 124 is the tangent direction of the preset direction, and the length range of the buckle portion 124 is 10 mm to 14 mm. A reasonable length of the buckle portion 124 can save materials and reduce production costs while ensuring the clamping and limiting effect. The length direction of the clearance hole 119 is also the tangent direction of the preset direction, and the difference between the length of the clearance hole 119 and the length of the buckle portion 124 is greater than or equal to 3 mm. A reasonable difference between the length of the clearance hole 119 and the length of the buckle portion 124 can facilitate the buckle portion 124 to pass through the clearance hole 119, thereby achieving a quick disassembly and assembly effect.

[0049] In this embodiment, the length of the buckle portion 124 ranges from 10 mm to 14 mm, and the difference between the length of the clearance hole 119 and the length of the buckle portion 124 is greater than or equal to 3 mm. However, this is not limited to this. In other embodiments, only the length of the buckle portion 124 is limited to 10 mm to 14 mm, or only the difference between the length of the clearance hole 119 and the length of the buckle portion 124 is limited to be greater than or equal to 3 mm.

[0050] It is worth noting that the difference between the width of the slot 117 and the width of the spring buckle 122 ranges from 1 mm to 2 mm, that is, the single-sided gap between the spring buckle 122 and the slot 117 (the gap between the spring buckle 122 and any side wall of the slot 117 perpendicular to the preset direction) ranges from 0.5 mm to 1 mm, so as to achieve reliable fit between the spring buckle 122 and the slot 117. A reasonable difference between the width of the slot 117 and the width of the spring buckle 122 can ensure the fit accuracy between the spring buckle 122 and the slot 117, and reliably fix the relative position of the connecting member 120 and the supporting platform 111.

[0051] In this embodiment, the number of the spring buckles 122, the slots 117 and the clearance holes 119 are all three, each spring buckle 122 is used to pass through a clearance hole 119 and is clamped with a slot 117, and the three spring buckles 122 are arranged in a circular array at the bottom of the connecting member 120. The three spring buckles 122 and the three slots 117 work together to further improve the clamping effect and prevent the connecting member 120 from being separated from the supporting platform 111. However, this is not limited to this. In other embodiments, the number of the spring buckles 122, the slots 117 and the clearance holes 119 can all be two or four, and the number of the spring buckles 122, the slots 117 and the clearance holes 119 is not specifically limited.

[0052] For ease of understanding, the length of the buckle portion 124 is represented as A, and the length of the clearance hole 119 is represented as B.

[0053] The beneficial effects of the wind wheel 100 described in the embodiment of the present invention are the same as those of the first embodiment, and will not be described in detail herein.

[0054] Third embodiment

The ceiling machine 10 includes a housing 200, a water tray 300 and a wind wheel 100. The basic structure and principle of the wind wheel 100 and the technical effects produced are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding contents in the first embodiment.

[0056] In this embodiment, the water tray 300 is connected to the housing 200, and the housing 200 is embedded in the indoor ceiling. The water tray 300 is provided with an air inlet 310, and the wind wheel 100 is detachably installed in the housing 200. The position of the wind wheel 100 corresponds to the position of the air inlet 310, so that the connecting member 120 and the wind wheel body 110 in the wind wheel 100 can be removed from the air inlet 310 in sequence, thereby facilitating the maintenance of the ceiling machine 10.

[0057] Specifically, the distance between the wind wheel 100 and the chassis foam 210 disposed on the bottom wall of the housing 200 is greater than or equal to 10 mm, that is, the distance between the wind wheel body 110 and the chassis foam 210 disposed on the bottom wall of the housing 200 is greater than or equal to 10 mm. A reasonable distance between the wind wheel 100 and the chassis foam 210 disposed on the bottom wall of the housing 200 can increase the activity space of the wind wheel body 110 while ensuring the external dimensions of the ceiling machine 10, so as to facilitate the tilted removal of the wind wheel body 110 from the air inlet 310. The maximum distance between the projection of the wind wheel 100 on the plane where the water tray 300 is located and the side wall of the air inlet 310 is greater than or equal to 15 mm, so as to increase the activity space of the wind wheel body 110, so as to facilitate the tilted removal of the wind wheel body 110 from the air inlet 310.

[0058] In this embodiment, the distance between the wind wheel 100 and the bottom plate foam 210 disposed on the bottom wall of the housing 200 is greater than or equal to 10 mm, and the maximum distance between the projection of the wind wheel 100 on the plane where the water tray 300 is located and the side wall of the air inlet 310 is greater than or equal to 15 mm. However, this is not limited to this. In other embodiments, only the distance between the wind wheel 100 and the bottom plate foam 210 disposed on the bottom wall of the housing 200 is greater than or equal to 10 mm, or only the maximum distance between the projection of the wind wheel 100 on the plane where the water tray 300 is located and the side wall of the air inlet 310 is greater than or equal to 15 mm.

[0059] For ease of understanding, the gap between the wind wheel 100 and the plane where the water receiving tray 300 is located is represented as C, the distance between the wind wheel 100 and the chassis foam 210 arranged on the bottom wall of the outer shell 200 is represented as D, and the maximum distance between the projection of the wind wheel 100 on the plane where the water receiving tray 300 is located and the side wall of the air inlet 310 is represented as E.

[0060] It is worth noting that during the disassembly of the wind wheel 100, the connecting piece 120 is first disassembled from the wind wheel body 110, and the connecting piece 120 is disassembled from the output shaft 610 of the driving motor 600; then, the connecting piece 120 is lifted in a direction perpendicular to the plane where the water collecting tray 300 is located in the direction close to the water collecting tray 300, so as to remove the connecting piece 120 outward from the air inlet 310, so that the connecting piece 120 is separated from the output shaft 610; then, the wind wheel body 110 is translated for a distance in the direction close to the side wall of the air inlet 310 (the distance between the side wall and the projection of the wind wheel 100 on the plane where the water collecting tray 300 is located is the largest) to avoid interference with other components when the wind wheel body 110 is tilted laterally; then, the wind wheel body 110 is taken out outwardly at an angle to make the wind wheel body 110 escape from the air inlet 310, and the disassembly of the wind wheel body 110 is completed, which is convenient, quick and efficient.

[0061] The beneficial effects of the ceiling machine 10 described in the embodiment of the present invention are the same as those of the first embodiment, and will not be described in detail herein.

[0062] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
