Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] The ceiling machine of this utility model is described below with reference to the accompanying drawings.

[0034] like Figures 1-8 As shown, the ceiling-mounted air conditioner of this utility model embodiment includes a housing 700, an air guide ring 500, and an electrical control box 200.

[0035] The housing 700 has a panel 710, on which an air inlet grille 711 is provided. An air guide ring 500 is disposed inside the housing 700, above the panel 710, and the air guide ring 500 and the air inlet grille 711 are correspondingly arranged. A frame 100 is provided inside the housing 700, on which air vents 110 are provided. The air guide ring 500 is located at the air vents 110, and the electrical control box 200 is disposed on the lower surface of the frame 100.

[0036] The electrical control box 200 of this utility model is described below with reference to the accompanying drawings.

[0037] like Figures 1-7 As shown, the electrical control box 200 of this embodiment of the utility model has a box body 290. The box body 290 includes a first part 291 and a second part 293.

[0038] The first portion 291 includes a first sidewall 292, defining a downward-opening first receiving cavity 296. A second portion 293 is disposed on one side of one end of the first portion 291 and is connected to the first sidewall 292. The second portion 293 includes a second sidewall 295 adjacent to the other end of the first portion 291, with the first sidewall 292 connected to the second sidewall 295. The second portion 293 defines a downward-opening second receiving cavity 297, communicating with the first receiving cavity 296. When the electrical control box 200 is mounted on the lower surface of the frame 100, the first sidewall 292 and the second sidewall 295 face the centerline of the guide vane 500, so that the electrical control box 200 avoids the air vent 110.

[0039] Electrical control components, such as a control board 800 and an electrical control terminal block 400, are installed in the first receiving cavity 296 and the second receiving cavity 297. That is, when the housing 290 is installed inside the housing 700, both the first receiving cavity 296 and the second receiving cavity 297 of the housing 290 are open downwards. The first part 291 is located on one side of the vent 110 in the horizontal direction, and the second part 293 is connected to the other end of the first part 291 and protrudes outward from the other end of the first part 291, so that the vent 110 is located between the first part 291 and the second part 293, so as to prevent the first part 291 and the second part 293 from blocking the air intake of the vent 110.

[0040] Specifically, such as Figures 1-7 As shown, the first part 291 is disposed on the lower surface of the frame 100 in the area in front of the air vent 110. The first part 291 extends in the left-right direction and its right end extends into the area to the right side of the air vent 110. The first part 291 extends in the front-back direction, and its front end is connected to the right end of the first part 291.

[0041] Compared with related technologies, the electrical control box 200 of this utility model embodiment has a box body 290 including a first part 291 and a second part 293. The second part 293 is disposed on one side of one end of the first part 291, and the second side wall 295 of the second part 293 is adjacent to the second side wall 295 of the other end of the first part 291. The first part 291 can be set on one side of the air guide ring 500 in the horizontal direction. The second part 293 is connected to the other end of the first part 291 and protrudes from the other end of the first part 291 to the other side of the first part 291, so that the air guide ring 500 is between the first part 291 and the second part 293. This not only avoids the first part 291 and the second part 293 from blocking the air intake of the air hole 110, but also, in addition to the first accommodating cavity 296 formed by the first part 291 which can accommodate the electronic control components, the housing 290 also has a second accommodating cavity 297 formed by the second part 293, thereby increasing the overall volume of the housing 290 and giving the housing 290 a larger installation space. Therefore, it is convenient for operators to assemble or maintain the electronic control components in the electronic control box 200 of this utility model embodiment.

[0042] like Figures 1-7 As shown, the ceiling machine of this utility model embodiment also includes a wire fixing structure 230, a first wire 210 and a second wire 220.

[0043] The remaining area on the lower surface of the frame 100 provides space for the first wire 210 and the second wire 220 to run. Furthermore, the control box 200 is installed on the lower surface of the frame 100 in an area that avoids the air vent 110, so that the control box 200 will not interfere with the normal air intake of the air vent 110 after it is installed on the frame 100.

[0044] The terminals of the first wire 210 and the second wire 220 are both installed inside the electrical control box 200, and the electrical control components of the ceiling machine are also installed inside the electrical control box 200, such as the control board 800 and the electrical control terminal block 400. Thus, the electrical control box 200 seals the terminals of the first wire 210 and the second wire 220 and the electrical control components, preventing external moisture from contacting them and thus preventing circuit failures in the ceiling machine of this embodiment.

[0045] One end of the electrical control box 200 is provided with a first wire passage hole 201, and the other end of the electrical control box 200 is provided with a second wire passage hole 202. A first wire 210 passes through the first wire passage hole 201 and exits the electrical control box 200, extending from the corresponding side of the vent 110 in a direction away from the electrical control box 200. A second wire 220 passes through the second wire passage hole 202 and exits the electrical control box 200, extending from the corresponding other side of the vent 110 in a direction away from the electrical control box 200. In other words, the electrical control box 200 is provided with a first wire passage hole 201 and a second wire passage hole 202 spaced apart in the horizontal direction, so that the first wire 210 and the second wire 220, respectively, pass through the first wire passage hole 201 and the second wire passage hole 202 and are distributed on both sides of the vent 110. This allows the first wire 210 and the second wire 220 to be distributed on both sides of the air vent 110, thereby adjusting the layout of the first wire 210 and the second wire 220 and making their distribution on the lower surface of the frame 100 more orderly.

[0046] In some embodiments, such as Figures 1-2 As shown, the ratio between the length of the second portion 293 along the width direction of the first portion 291 and the width of the first portion 291 is 4 / 5 to 6 / 5. The ceiling machine of this embodiment will be further described below, taking as an example that the length direction of the first portion 291 is consistent with the left-right direction and as an example that the width direction of the first portion 291 is consistent with the front-back direction.

[0047] The ratio between the length of the second part 293 along the width direction of the first part 291 and the width of the first part 291 includes, but is not limited to, 4 / 5, 1, and 6 / 5. This fully utilizes the space outside the vent 110, increases the volume of the second part 293, and avoids messy wiring inside the housing 290. Furthermore, it prevents the width of the second part 293 from being too large and obstructing the first wire 210 from passing through the frame 100.

[0048] In some embodiments, such as Figures 1-5 As shown, the second sidewall 295 is an arc-shaped wall recessed into the housing 290. The second sidewall 295 can accommodate the air guide ring 500, thereby further increasing the volume of the housing 290 and providing more installation space inside the housing 290. This, in turn, allows for more space for wiring inside the housing 290. After the first wire 210 and the second wire 220 are connected to the electrical control components inside the housing 290, they can be dispersed. This not only avoids messy wiring inside the housing 290, but also facilitates wiring operations for the operator.

[0049] In some embodiments, such as Figures 1-5As shown, the second part 293 includes an end wall 294, which is connected to the end of the second side wall 295 away from the first side wall 292. The end wall 294 is provided with at least one first wire-passing hole 201; and / or, the end of the first side wall 292 away from the second side wall 295 is provided with at least one second wire-passing hole 202. That is, the end wall 294 is connected to the rear end of the second side wall 295. The first wire-passing hole 201 is provided on the end wall 294, and the second wire-passing hole 202 is provided at the end of the first side wall 292 away from the second side wall 295.

[0050] Specifically, such as Figure 2 As shown, the first part 291 is disposed on the lower surface of the frame 100 in the area in front of the air vent 110. The first part 291 extends in the left-right direction and its right end extends into the area to the right of the air vent 110. The first part 291 extends in the front-back direction, and its front end is connected to the right end of the first part 291. This increases the volume of the housing 290, giving the housing 290 a larger installation space, and thus providing more space for wiring inside the housing 290. After the first wire 210 and the second wire 220 are connected to the electrical control components inside the housing 290, they can be dispersed, which not only avoids messy wiring inside the housing 290, but also makes it easier for operators to perform wiring operations.

[0051] In some embodiments, such as Figure 7 As shown, a plurality of first wire-passing holes 201 are provided on the end wall 294, and the plurality of first wire-passing holes 201 are spaced apart in the vertical / horizontal direction. For example Figure 6 As shown, there are two first wire-passing holes 201, which are spaced apart in the left-right direction on the end wall 294.

[0052] The first wire 210 includes a power wire 211, a first high-voltage wire 212, and / or a first low-voltage wire 213. The power wire 211 and the first high-voltage wire 212 exit through one first through-hole 201, and the first low-voltage wire 213 exits through another first through-hole 201; or, the power wire 211 exits through one first through-hole 201, and the first low-voltage wire 213 and the first high-voltage wire 212 exit through another first through-hole 201; or, the power wire 211 exits through one first through-hole 201, and the first low-voltage wire 213 and the first high-voltage wire 212 exit through another first through-hole 201.

[0053] In some embodiments, such as Figure 7As shown, there are at least two second wire guide holes 202, arranged sequentially along the length of the first portion 291. There are multiple first wire guide holes 201, arranged in at least two rows along the height direction, with at least one first wire guide hole 201 in each row. Thus, multiple first wire guide holes 201 and multiple second wire guide holes 202 are used to arrange multiple wires in the first wire 210 (e.g., power cord 211, first high-voltage wire 212, and / or first low-voltage wire 213) and multiple wires in the second wire 220, respectively. This makes the arrangement of the first wire 210 and the second wire 220 more reasonable, avoids messy wiring inside the housing 290, and facilitates wiring operations for the operator.

[0054] Furthermore, one or more first wire-passing holes 201 are notches penetrating the lower edge of the end wall 294, and one or more second wire-passing holes 202 are notches penetrating the lower edge of the second side wall 295. Using the notches at the lower edge of the end wall 294 to form one or more first wire-passing holes 201, and using the notches at the lower edge of the second side wall 295 to form one or more second wire-passing holes 202, not only results in a simple structure but also ease of manufacturing.

[0055] Protective rings for wire passage are provided at both the first wire passage hole 201 and the second wire passage hole 202. Thus, after the first wire 210 and the second wire 220 pass through the first wire passage hole 201 and the second wire passage hole 202 respectively, the protective rings seal the first wire passage hole 201 and the second wire passage hole 202, preventing external moisture from contacting the terminals of the first wire 210, the second wire 220, the control board 800, and the electrical control terminal block 400, thereby avoiding circuit failures in the ceiling-mounted machine of this embodiment.

[0056] Optionally, the protective ring is a rubber ring.

[0057] In some embodiments, such as Figure 5 and Figure 6 As shown, the electrical control box 200 of this embodiment also includes a cover 600, which is detachably installed at the opening of the receiving cavity. The cover 600 and the box body 290 are connected by screws, threaded assemblies, and / or snap fasteners. The cover 600 and the box body 290 are respectively provided with threaded holes or through holes to fix the cover 600 and the box body 290. Alternatively, the cover 600 and the box body 290 are respectively provided with snap fasteners and slots. This facilitates the assembly of the cover 600 and the box body 290, and the structure is simple and easy to manufacture.

[0058] In some embodiments, such as Figure 7 and Figure 8As shown, there are multiple wire-fixing structures 230, which are disposed on the lower surface of the frame 100. A portion of each wire-fixing structure 230 is disposed on the lower surface of the frame 100 and a portion of the first wire-passing hole 201, allowing the first wire 210 to pass through the first wire-passing hole 201 and be installed on the corresponding wire-fixing structure 230. Another portion of each wire-fixing structure 230 is disposed on the lower surface of the frame 100 and a portion of the second wire-passing hole 202, allowing the second wire 220 to pass through the second wire-passing hole 202 and be installed on the corresponding wire-fixing structure 230. Thus, the wire-fixing structures 230 are used to fix the first wire 210 and the second wire 220 respectively, preventing the wire bundles of the first wire 210 and the second wire 220 from becoming entangled.

[0059] The two corners of the lower surface of the frame 100, located on the side of the second portion 293 opposite to the first portion 291, are the first corner 120 and the second corner 130, respectively, which are the rear portion of the lower surface of the frame 100. The distance from the first corner 120 to the second portion 293 is less than the distance from the second corner 130 to the second portion 293. The wire fixing structure 230 includes a first structure 231, which is disposed at the first corner 120 of the frame 100. The first structure 231 is configured to fix the first wire 210. The power wire 211, the high-voltage wire, and / or the first low-voltage wire 213 pass through the frame 100 from the first structure 231. That is, after the first wire 210 passes through the first wire hole 201, the first wire 210 passes through the frame 100 from the first corner 120 near the first wire hole 201.

[0060] The wiring structure 230 also includes a second structure 240. The second structure 240 includes a first boss 241, a second boss 242, and a pressure strip 243. The first boss 241 is connected to the frame 100, and the second boss 242 is connected to the frame 100, with the second boss 242 spaced apart from the first boss 241. The pressure strip 243 is installed on the first boss 241 and the second boss 242, forming a first wire 210 hole with the first boss 241 and the second boss 242. One of the second structures 240 is disposed between the first structure 231 and the second part 293, and some or all of the first wires 210 pass through the first wire 210 hole of the second structure 240. That is, at least one of the power cord 211, the high-voltage wire, and the first low-voltage wire 213 passes through the first wire 210 hole of the second structure 240. In other words, by setting a second structure 240 between the first structure 231 and the second part 293, and using the second structure 240 to fix the part of the first wire 210 located between the first structure 231 and the second part 293, the arrangement of the first wire 210 is more orderly, and the first wire 210 is prevented from extending to the air hole 110, thus ensuring that the air hole 110 can intake air normally.

[0061] In some embodiments, such as Figure 5 and Figure 6 As shown, the ceiling-mounted ceiling machine of this embodiment further includes a control board 800 and an electrical control terminal block 400. The control board 800 is disposed in the first receiving cavity 296. The electrical control terminal block 400 is disposed in the second receiving cavity 297; the electrical control terminal block 400 is electrically connected to the control board 800. The electrical control terminal block 400 is disposed in the second receiving cavity 297 and is electrically connected to the control board 800. The control board 800 and the electrical control terminal block 400 are installed in the electrical control box 200, thereby sealing the terminals of the first wire 210, the second wire 220, the control board 800, and the electrical control terminal block 400 through the electrical control box 200, preventing external moisture from contacting the terminals of the first wire 210, the second wire 220, the control board 800, and the electrical control terminal block 400, and avoiding circuit failure of the ceiling-mounted ceiling machine of this embodiment.

[0062] In some embodiments, such as Figure 5 and Figure 6 As shown, the ceiling-mounted air conditioner of this embodiment also includes a water collection tray 150, which is disposed within the housing 700 and located outside the air guide ring 500. The housing 290 of the electrical control box 200 is mounted on the water collection tray 150. The arc-shaped wall of the electrical control box 200 is located outside the air guide ring 500; or, the arc-shaped wall of the electrical control box 200 is located below the air guide ring 500; or, a notch is provided at the lower end of the air guide ring 500, and the arc-shaped wall of the electrical control box 200 is located at the notch. The electrical control box 200 can separate the electrical control components from the water collection tray 150, preventing water in the water collection tray 150 from contacting the electrical control components.
