DETAILED DESCRIPTION

[0032] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0033] Please refer to Figures 1 to 3 The embodiments of the present application provide a ceiling machine 100 for regulating indoor air temperature. It can simplify the disassembly structure, reduce the number of parts that need to be disassembled during maintenance, reduce the operation risk and maintenance difficulty, save labor cost and time cost, and improve user experience.

[0034] It should be noted that the ceiling machine 100 is installed on the indoor ceiling, the middle position of the bottom surface is used for air inlet, and the periphery of the bottom surface is used for air outlet. The ceiling machine 100 can heat exchange during air flow to make the air flow blown out from the periphery of the bottom surface of the ceiling machine 100 realize the function of heating or cooling, so as to regulate the indoor air temperature. Specifically, during the maintenance of the ceiling machine 100, it is generally necessary to first climb to the height of the ceiling machine 100 using a ladder, and then disassemble the shielding parts of the bottom surface of the ceiling machine 100, so as to maintain or replace the parts in the ceiling machine 100.

[0035] The ceiling machine 100 comprises a shell 110, a water pan 120, an electric control box 130, an air guide ring 140, a driving motor 150 and a fan wheel 160. The water pan 120 is connected with the shell 110, and the water pan 120 is provided with an air inlet 121 for air to flow into the ceiling machine 100 to realize the air inlet function of the ceiling machine 100. The air guide ring 140 is arranged outside the air inlet 121, and the air guide ring 140 is used for guiding the air inlet airflow to improve the air inlet efficiency. Specifically, the shell 110 is embedded in the indoor ceiling, the water pan 120 is arranged at the bottom of the shell 110, and the water pan 120 and the air guide ring 140 are located on the bottom surface of the ceiling machine 100. During the maintenance of the ceiling machine 100, the air guide ring 140 needs to be disassembled from the water pan 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 installed on the water pan 120, and a stop groove 170 is formed between the electric control box 130 and the water pan 120. The air guide ring 140 is provided with an extension strip 141, and the extension strip 141 cooperates with the stop groove 170. The stop groove 170 can limit the extension strip 141, thereby limiting the entire air guide ring 140, and further fixing the relative position of the air guide ring 140, the electric control box 130 and the water pan 120. The water pan 120 is provided with a buckle 122, and the air guide ring 140 is provided with a clamping hole 142. The buckle 122 is clamped with the clamping hole 142 to fix the relative position of the air guide ring 140 and the water pan 120, and prevent the air guide ring 140 from being separated from the water pan 120. Accordingly, during the maintenance of the ceiling machine 100, only the clamping state of the buckle 122 and the clamping hole 142 needs to be released, and the extension strip 141 needs to be pulled out of the stop groove 170, so that the air guide ring 140 can be disassembled conveniently and quickly. In this way, the disassembly structure of the air guide ring 140 is simplified, the air guide ring 140 can be disassembled without disassembling the electric control box 130, the number of parts to be disassembled during maintenance is reduced, the operation risk and maintenance difficulty are reduced, the labor cost and time cost are saved, and the user experience is improved.

[0037] It should be noted that the driving motor 150 is installed in the shell 110 and detachably connected with 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 realize 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 worker can disassemble the wind wheel 160 through the air inlet 121 to facilitate the maintenance or replacement of the wind wheel 160. Specifically, the minimum distance between the projection of the wind wheel 160 on the plane where the water pan 120 is located and the side wall of the air inlet 121 is greater than or equal to 10 mm, and the distance between the wind wheel 160 and the plane where the water pan 120 is located is greater than or equal to 30 mm, so as to facilitate the disassembly of the wind wheel 160 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 the preset direction and communicate with each other. 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 assembly of the buckle 122 into the clamping hole 142. The second hole section 1422 is used for cooperating with the buckle 122 after the air guide ring 140 slides a preset distance relative to the water pan 120 along the preset direction, that is, the buckle 122 and the clamping hole 142 have a certain stroke. After the buckle 122 passes through the first hole section 1421, the buckle 122 and the second hole section 1422 are connected by moving the air guide ring 140 a certain stroke along the preset direction. Correspondingly, when the clamping state of the buckle 122 and the clamping hole 142 is released, the air guide ring 140 needs to be slid a preset distance in the opposite direction first to make the buckle 122 out of the second hole section 1422, and then the air guide ring 140 is disassembled from the water pan 120. In this process, the buckle 122 passes out of the first hole section 1421, and the buckle 122 does not interfere with the disassembly of the air guide ring 140. In this way, since the width of the first hole section 1421 is larger and the width of the second hole section 1422 is smaller, the assembly reliability of the buckle 122 and the clamping hole 142 can be ensured, and the installation and disassembly are facilitated, which is convenient and practical.

[0039] Further, the difference between the width of the first hole section 1421 and the width of the buckle 122 is in the range of 4 mm to 6 mm, that is, the single-side gap (the gap between the buckle 122 and the first hole section 1421 on any side wall perpendicular to the preset direction) of the buckle 122 and the first hole section 1421 is in the range of 2 mm to 3 mm, so as to realize the coarse positioning of the buckle 122 by the first hole section 1421. The reasonable difference between the width of the first hole section 1421 and the width of the buckle 122 can ensure the coarse positioning effect of the first hole section 1421 on the buckle 122 while facilitating the buckle 122 to pass through the first hole section 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, i.e. the single-side gap (the gap between the buckle 122 and the second hole section 1422 in any side wall perpendicular to the preset direction) of the buckle 122 and the second hole section 1422 ranges from 0.5 mm to 1 mm, so as to realize reliable cooperation between the second hole section 1422 and the buckle 122, and the reasonable difference between the width of the second hole section 1422 and the width of the buckle 122 can ensure the cooperation accuracy of the buckle 122 and the second hole section 1422, and reliably fix the relative position of the air guide ring 140 and the water pan 120.

[0041] In the embodiment, the difference between the width of the first hole section 1421 and the width of the buckle 122 ranges from 4 mm to 6 mm, and 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. However, it is not limited to this, in other embodiments, only the difference between the width of the first hole section 1421 and the width of the buckle 122 ranges from 4 mm to 6 mm, or only 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.

[0042] It is worth noting that the gap between the side wall of the clamping 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 clamping hole 142, thereby ensuring the reliability of the cooperation between the clamping hole 142 and the buckle 122, and avoiding the edge of the air guide ring 140 from being warped.

[0043] The buckle 122 includes a connecting part 1221 and a clamping part 1222 connected with each other. The connecting part 1221 is connected to the water pan 120, and the clamping part 1222 is arranged perpendicular to the connecting part 1221. The clamping part 1222 is used to pass through the clamping hole 142, so as to clamp the air guide ring 140 between the clamping part 1222 and the water pan 120, thereby fixing the relative position of the air guide ring 140 and the water pan 120, and preventing the air guide ring 140 from being separated from the water pan 120. Specifically, in the assembly process of the buckle 122 and the clamping hole 142, the air guide ring 140 is first moved to be attached to the water pan 120, so that the clamping part 1222 passes through the first hole section 1421 of the clamping hole 142, and then the air guide ring 140 is slid relative to the water pan 120 along the preset direction by a preset distance, so that the clamping part 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 part 1222 and the water pan 120, and the assembly is completed.

[0044] Further, the length direction of the clamping part 1222 is the preset direction, and the length of the clamping part 1222 ranges from 7 mm to 15 mm. The reasonable length of the clamping part 1222 can save materials while ensuring the clamping limiting effect on the air guide ring 140, thereby reducing the production cost.

[0045] It should be noted that when the buckle 122 is assembled with the card hole 142, and the air guide ring 140 slides a predetermined distance relative to the water pan 120 in the predetermined direction, the extension bar 141 of the air guide ring 140 is synchronized with the stop slot 170 in the predetermined direction, and cooperates with the stop slot 170. Specifically, the width direction of the extension bar 141 is the same as the length direction of the clamping part 1222, that is, the width direction of the extension bar 141 is the same as the predetermined direction, and the ratio of the width of the extension bar 141 to the length of the clamping part 1222 is in the range of 0.8 to 1.5. A reasonable ratio of the width of the extension bar 141 to the length of the clamping part 1222 can ensure the reliability of the cooperation between the extension bar 141 and the stop slot 170, and prevent the extension bar 141 from accidentally coming out of the stop slot 170.

[0046] In the embodiment, the number of buckles 122 and card holes 142 is four, and each buckle 122 is clamped and matched with a card hole 142. Among them, the four card holes 142 are divided into two groups, and the two groups of card holes 142 are oppositely arranged at the two ends of the air guide ring 140. The four buckles 122 and the four card holes 142 jointly act to improve the reliability of the connection between the air guide ring 140 and the water pan 120, and prevent the air guide ring 140 from accidentally separating from the water pan 120.

[0047] In the embodiment, the air guide ring 140 is provided with a through hole 143, the through hole 143 and the extension bar 141 are oppositely arranged at the two ends of the air guide ring 140, and the water pan 120 is provided with a threaded hole 123. 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 pan 120, and prevent the air guide ring 140 from separating from the water pan 120. Specifically, the through hole 143 and the extension bar 141 are oppositely arranged at the left and right ends of the air guide ring 140, and the two groups of card holes 142 are oppositely arranged at the front and rear ends of the air guide ring 140. The through hole 143, the extension bar 141 and the two groups of card holes 142 jointly act to realize multi-directional 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 pan 120 is provided with a limiting groove 124, the air inlet 121 is arranged on the bottom wall of the limiting groove 124, the buckle 122 is arranged on the bottom wall of the limiting groove 124, and the air guide ring 140 is arranged in the limiting groove 124. The limiting groove 124 is used to limit the air guide ring 140, and prevent the air guide ring 140 from being displaced relative to the water pan 120 under the action of vibration when the ceiling machine 100 is running. Specifically, the air guide ring 140 is arranged in close contact with the bottom wall of the limiting groove 124, and the minimum distance between the air guide ring 140 and the side wall of the limiting groove 124 is in the range of 1 millimeter to 2 millimeters. A reasonable distance between the air guide ring 140 and the side wall of the limiting groove 124 can ensure the sealing property, prevent air from entering the ceiling machine 100 from the gap between the air guide ring 140 and the water pan 120, and facilitate disassembly and assembly.

[0049] Further, the air guide ring 140 is provided with an end wall 147 away from one side of the extension bar 141, and the end wall 147 comprises a first wall body 1471, a second wall body 1472 and a third wall body 1473 connected in sequence. The first wall body 1471 is located corresponding to the position of one set of buckles 122, and the third wall body 1473 corresponds to the position of another set of buckles 122. Specifically, the first wall body 1471 has a first gap with the side wall of the limiting groove 124, and the difference between the length of the first gap and the length of the clamping part 1222 is greater than or equal to 2mm. 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 a preset distance) in the preset direction, so as to realize the cooperation of the buckle 122 and the clamping hole 142; the third wall body 1473 has a second gap with the side wall of the limiting groove 124, and the second gap is equal to the first gap. The difference between the length of the second gap and the length of the clamping part 1222 is greater than or equal to 2mm. 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 a preset distance) in the preset direction, so as to realize the cooperation of 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 disassembly, so as to facilitate the disassembly of the air guide ring 140. During the assembly of the air guide ring 140 and the water pan 120, the air guide ring 140 is elastically deformed. The first wall body 1471 and the third wall body 1473 slide in the limiting groove 124, and the second wall body 1472 slides in the limiting groove 124 under the guidance of the inclined side wall of the limiting groove 124 until the buckle 122 is clamped with the clamping hole 142. At this time, the second wall body 1472 and the side wall of the limiting groove 124 form the minimum gap.

[0051] In the embodiment, the air guide ring 140 is provided with a pulling part 144, the water tray 120 is provided with a clearance slot 125, the pulling part 144 covers part of the clearance slot 125, the clearance slot 125 is used for the fingers of the staff to extend into, so as to facilitate the staff to exert force on the pulling part 144, and the air guide ring 140 is pulled out in the direction away from the water tray 120 through the pulling part 144, so that part of the air guide ring 140 is separated from the limiting slot 124, then the staff can pull out the air guide ring 140 through the pulling part 144, so that the buckle 122 is separated from the clamping hole 142, and the extension strip 141 is separated from the stop slot 170, thereby achieving the disassembly of the air guide ring 140. Specifically, the depth of the clearance slot 125 is greater than or equal to 5 mm, and the width of the pulling part 144 is greater than or equal to 25 mm, so that the fingers of the staff can extend into the clearance slot 125, and the staff can easily exert force on the pulling part 144.

[0052] Further, the air guide ring 140 is also provided with two side edges 148, the end wall 147 and the extension strip 141 are arranged between the two side edges 148, the number of the pulling part 144 is two, and each pulling part 144 is arranged close to one side edge 148. Specifically, the distance between the pulling part 144 and the side edge 148 ranges from 30 mm to 60 mm, and the reasonable distance between the pulling part 144 and the side edge 148 can ensure the strength of the pulling part 144 and facilitate the staff to exert force to disassemble the air guide ring 140.

[0053] In the embodiment, the air guide ring 140 extends 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 the air guide ring 140 and the wind wheel 160 have a third gap on the plane where the water tray 120 is located, and the difference between the length of the clamping part 1222 and the third gap is greater than or equal to 3 mm, and the reasonable third gap can ensure that the wind wheel 160 will not block the air guide ring 140 during disassembly, thereby facilitating the disassembly of the air guide ring 140. But it is not limited to this, in other embodiments, the air guide ring 140 can also 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, and the third gap does not need to be limited, and the wind wheel 160 will not block the air guide ring 140 during disassembly.

[0054] The air guide ring 140 comprises a ring body 145 and a protective net 146. The protective net 146 is connected to the middle part of the ring body 145, the extending strip 141 and the clamping hole 142 are 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 for guiding the air flow, and the protective net 146 is also used for preventing external objects from accidentally extending into the air inlet 121. Specifically, the thickness of the protective net 146 ranges from 2 mm to 3 mm, and the reasonable thickness of the protective net 146 can reduce noise while ensuring strength and improve the air inlet amount.

[0055] In the embodiment, the ring body 145 and the protective net 146 are integrally formed to improve the connection strength, but are not limited thereto. In other embodiments, the ring body 145 and the protective net 146 can be separately arranged and detachably connected through screws or buckles, and the connection mode of the ring body 145 and the protective net 146 is not specifically limited.

[0056] In the embodiment, the protective net 146 is circularly arranged, and a plurality of rib strips 1461 are arranged along the radial direction and the circumferential direction of the circle. The spacing between the two adjacent radial rib strips 1461 ranges from 7 mm to 10 mm, and the spacing between the two adjacent radial rib strips 1461 is proportional to the air inlet amount. The reasonable spacing between the two adjacent radial rib strips 1461 can increase the air inlet amount as much as possible while preventing external objects from accidentally extending into the air inlet 121.

[0057] In the embodiment, the protective net 146 protrudes from the ring body 145, and the spacing between the plane where the protective net 146 is located and the plane where the ring body 145 is located ranges from 10 mm to 16 mm. The spacing 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 inlet amount. The reasonable spacing between the plane where the protective net 146 is located and the plane where the ring body 145 is located can increase the air inlet amount as much as possible under the size limitation of the ceiling machine 100.

[0058] In addition, in order to embody the beneficial effects of the present application, the inventor has conducted a plurality of comparative experiments, and the experimental results are as follows:

[0059] Thickness / mm Rib spacing / mm Guard height / mm Air intake quantity / 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] From the above table, if the thickness of the protective net 146 is too small (1.5 mm), the strength of the protective net 146 will be affected, and resonance sound will be generated during the operation of the ceiling machine 100, resulting in increased noise. Therefore, the thickness of the protective net 146 is preferably 2-3 mm. If the distance between the two adjacent radial ribs 1461 is too small (5-6 mm), the air inlet amount will be greatly reduced, directly affecting the effect of the ceiling machine 100. Therefore, the distance between the two adjacent radial ribs 1461 is preferably 7-10 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 (8 mm), the air inlet amount will be greatly reduced, directly affecting 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 10-16 mm.
