DETAILED DESCRIPTION

[0029] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0030] The ceiling machine provided in the embodiment of the present application is as follows: Figures 1 to 8 As shown, it includes: a chassis 100; a water receiving tray 200, which is arranged at the opening of the chassis 100 and surrounds a mounting hole 210; an air guide ring 300, which is located at the mounting hole 210 and is arranged on the water receiving tray 200 on a side of the bottom wall of the water receiving tray 200 that is away from the chassis 100, the air guide ring 300 surrounds an air hole 310, the air hole 310 is located on the inner side of the mounting hole 210, and an avoidance gap 320 is provided at the outer edge of the air guide ring 300, and the avoidance gap 320 is opposite to the side of the bottom wall of the water receiving tray 200 that is away from the chassis 100; and an electric control box 400, which is located in the avoidance gap 320 and is arranged on the water receiving tray 200.

[0031] In the ceiling machine, the air guide ring 300 and the electric control box 400 are all arranged on the water receiving tray 200, and there is no direct connection structure between the air guide ring 300 and the electric control box 400. In this way, before removing the air guide ring 300, it is no longer necessary to remove the electric control box 400 from the water receiving tray 200 in advance, so the maintenance process of the ceiling machine is simpler and less difficult to operate. In addition, the electric control box 400 cooperates with the mouth wall of the avoidance gap 320, and the air guide ring 300 is pre-positioned during the installation process of the air guide ring 300, so the assembly speed of the air guide ring 300 on the water receiving tray 200 is faster.

[0032] In some examples, such as Figure 1 , Figures 5 to 8As shown, the ceiling machine also includes: a fan assembly 500, which is fixed in the chassis 100 and opposite to the air hole 310, and the fan assembly 500 is configured to be disassembled and assembled from the mounting hole 210; and an open annular heat exchanger 600, the heat exchanger 600 is arranged in the chassis 100, and the fan assembly 500 is located on the inner side of the area enclosed by the heat exchanger 600.

[0033] When the fan assembly 500 is damaged, first remove the connection line between the fan assembly 500 and the electrical control box 400, then remove the air guide ring 300 on the water tray 200, and then remove and take out the fan assembly 500 from the mounting hole 210. This process does not require removal of the electrical control box 400 on the water tray 200, so the disassembly and assembly process of the fan assembly 500 is simpler and less difficult to operate.

[0034] In some examples, such as Figures 1 to 6 As shown, the electric control box 400 includes: an electric control box body 410, the electric control box body 410 is located in the avoidance gap 320 and is arranged on the water receiving tray 200, and the connection line of the fan assembly 500 is electrically connected to the electric control box body 410; and an electric control box cover 420, the opening of the electric control box body 410 is facing away from the water receiving tray 200, the electric control box cover 420 is located on the side of the electric control box body 410 facing away from the water receiving tray 200, and is covered on the opening of the electric control box body 410.

[0035] When the fan assembly 500 is damaged, the electric control box cover 420 can be removed from the electric control box body 410 to remove the connection line between the fan assembly 500 and the electric control box body 410 without removing the electric control box body 410 from the water tray 200 .

[0036] In some examples, such as Figures 2 to 5 As shown, the inner edge of the water receiving tray 200 is provided with a mounting edge 220 extending radially inwardly of the water receiving tray 200, and the mounting edge 220 is provided with a mounting hole 210, and the air guide ring 300 and the electric control box 400 are both fixedly mounted on the mounting edge 220. Among them, the mounting edge 220 is provided with a first screw hole 240 and a second screw hole 250, the air guide ring 300 is provided with a first through hole, and the electric control box 400 is provided with a second through hole, the first screw passes through the first through hole and is screwed to the first screw hole 240, and the second screw passes through the second through hole and is screwed to the second screw hole 250. In this solution, the first screw hole 240 and the second screw hole 250 are both located outside the water collecting groove of the water receiving tray 200, and the structure of the water collecting groove of the water receiving tray 200 is not damaged, so as to ensure that the water collecting groove of the water receiving tray 200 can normally store water.

[0037] In some examples, such as Figures 2 to 4As shown, the mounting edge 220 is provided with a wire hole 230, and the walls of the electric control box body 410 and the avoidance gap 320 cover the wire hole 230 together to prevent air leakage at the wire hole 230, and the connection line of the fan assembly 500 is electrically connected to the electric control box body 410 through the wire hole 230 by plug-in connection. Among them, one end of the wire hole 230 is connected to the mounting hole 210 and the other end is closed, the wall of the avoidance gap 320 covers the through end of the long hole, and the closed end of the long hole is located in the avoidance gap 320, which is not only conducive to the connection line of the fan assembly 500 to pass through the wire hole 230, but also the connection line of the fan assembly 500 will not escape from the through end of the long hole in the long hole due to being blocked by the wall of the avoidance gap 320.

[0038] In some examples, such as Figure 1 , Figures 5 to 8 As shown, the fan assembly 500 includes: a motor, which is fixed to the bottom wall of the chassis 100 and electrically connected to the electric control box 410; and a wind wheel 520, which is located between the motor and the air guide ring 300 and connected to the motor. The motor drives the wind wheel 520 to rotate, forming a wind beam that is blown from the air hole 310 through the wind wheel 520 to the heat exchanger 600.

[0039] Among them, Figure 5 , Fig. 9 and Fig.10 As shown, the projection of the electric control box 400 on the bottom wall of the chassis 100 and the projection of the wind wheel 520 on the bottom wall of the chassis 100 have an overlapping area, and the center of the mounting hole 210 is located on the side of the axis of the wind wheel 520 away from the electric control box 400, that is, in the process of removing the wind wheel 520 from the motor, the position of the electric control box 400 fixed on the water receiving tray 200 will block the wind wheel 520, and the inner bottom surface of the chassis 100 is provided with an avoidance groove 110, and the avoidance groove 110 is arranged to avoid the end of the wind wheel 520 adjacent to the bottom wall of the chassis 100 during the process of the wind wheel 520 being removed from the motor in an inclined state and being taken out of the mounting hole 210 in an inclined state, so as to avoid the end of the wind wheel 520 adjacent to the bottom wall of the chassis 100 from contacting the bottom wall of the chassis 100. In this scheme, the inclination angle of the wind wheel 520 is larger, which is more conducive to the end of the wind wheel 520 away from the bottom wall of the chassis 100 entering the mounting hole 210 more.

[0040] In the process of removing the wind wheel 520 of the ceiling machine of this scheme, it is necessary to remove the air guide ring 300 in advance, but it is not necessary to remove the electric control box 400 in advance. When the wind wheel 520 is about to be removed from the motor, the wind wheel 520 is removed in a tilted state. Since the avoidance groove 110 on the inner bottom surface of the chassis 100 will avoid the end of the wind wheel 520 adjacent to the bottom wall of the chassis 100 (that is, the end of the wind wheel 520 opposite to the electric control box 400), the inclination angle of the wind wheel 520 will be increased (that is, the end of the wind wheel 520 away from the bottom wall of the chassis 100 will enter the mounting hole 210 more), which is more conducive to removing the wind wheel 520 from the motor in a tilted state and taking it out from the mounting hole 210 in a tilted state. Correspondingly, the required size of the mounting hole 210 is also smaller. Therefore, the maintenance process of the ceiling machine of this scheme is simpler and less difficult to operate, and the strength of the water tray is higher.

[0041] In some examples, such as Fig.11 As shown, the avoidance groove 110 is in a ring shape, so that the strength of the chassis 100 is higher. Fig.11 As shown, a reinforcement groove 120 is provided on the inner bottom surface of the avoidance groove 110 , and the reinforcement groove 120 can improve the strength of the avoidance groove 110 and prevent the avoidance groove 110 from being deformed.

[0042] The outer diameter of the avoidance groove 110 is 360 mm to 480 mm, the width is 50 mm to 80 mm, and the depth is 8 mm to 12 mm. The axial distance between the wind wheel 520 and the water receiving tray 200 is 9 mm to 11 mm. The installation stroke of the wind wheel 520 on the motor is 9.5 mm to 11.5 mm. The axial distance between the bottom wall of the chassis and the water receiving tray is 160 mm to 180 mm. The diameter of the wind wheel 520 is 466 mm to 476 mm, and the height is 126 mm. mm~138mm, and the length of the mounting hole 210 is greater than the diameter of the wind wheel 520, the width of the mounting hole 210 is greater than the height of the wind wheel 520, and the diameter of the mounting ring 522 of the wind wheel 520 gradually increases from the end adjacent to the air guide ring 300 to the end adjacent to the bottom wall of the chassis 100. In this way, when the wind wheel 520 is disassembled, it is more conducive to the end of the wind wheel 520 away from the chassis 100 to extend into the mounting hole 210, so the wind wheel 520 is easier to be disassembled from the motor and taken out from the mounting hole 210.

[0043] Among them, Fig.11 As shown, the mounting hole 210 is a rectangular hole, and the four angles of the mounting hole 210 are all arc chamfers. The distance between a set of opposite sides of the mounting hole 210 is the width of the mounting hole 210. The electric control box 400 is fixed on one of the opposite sides of the mounting hole 210, and the distance between the other set of opposite sides of the mounting hole 210 is the length of the mounting hole 210. Figure 2 and Fig.11As shown, the shape enclosed by the outer edges of the installation edge 220 is also a quasi-square, and the width of the area on the installation edge 220 where the electric control box 400 is arranged is greater than the width of other areas on the installation edge 220 .

[0044] Furthermore, if Figures 6 to 8 As shown, the motor is an outer rotor motor 510, and a mounting stud 511 is protruded on the side of the outer rotor of the outer rotor motor 510 facing the air guide ring 300, and the height H of the mounting stud 511 is 9.5mm-11.5mm (i.e., the installation stroke of the wind wheel 520 on the outer rotor motor 510), so the distance between the wind wheel 520 and the bottom wall of the chassis 100 is small (while the extension length of the motor shaft of the inner rotor motor is generally greater than 50mm, resulting in a larger distance between the wind wheel and the bottom wall of the chassis). Figures 9 to 11 As shown, the wheel disc of the wind wheel 520 has a receiving groove 521 that is recessed away from the outer rotor motor, and the end wall of the receiving groove 521 has a third through hole. The outer rotor motor 510 is located in the receiving groove 521, so that the distance between the wind wheel 520 and the water receiving tray 200 is smaller, so the height of the chassis 100 is smaller. In this solution, the distance between the wind wheel 520 and the water receiving tray 200 is 9mm to 11mm. When the wind wheel 520 is disassembled at an angle, the end of the wind wheel 520 adjacent to the bottom wall of the chassis 100 will extend into the avoidance groove 110, and the end of the wind wheel 520 away from the bottom wall of the chassis 100 will extend into the mounting hole 210. The inclination angle of the wind wheel 520 is larger, and it is easier to disassemble from the motor and take it out from the mounting hole 210. Among them, the mounting stud 511 is penetrated in the third through hole and is tightened with a nut 700 to fix the wind wheel 520 on the outer rotor of the motor. Compared with the solution in which the wind wheel 520 is installed on the motor shaft of the inner rotor motor (the protruding length of the motor shaft of the inner rotor motor is generally greater than 50 mm), the distance between the wind wheel 520 and the bottom wall of the chassis 100 is closer and the height of the chassis 100 is smaller.

[0045] Preferably, the mounting studs 511 and the third through holes include a plurality of groups uniformly distributed in the circumferential direction of the outer rotor, so that relative rotation between the wind wheel 520 and the outer rotor can be better avoided.

[0046] It may be that the mounting studs 511 and the third through holes include two groups symmetrically arranged in the circumferential direction of the outer rotor; or it may be that Figures 6 to 8 As shown, the mounting studs 511 and the third through holes include three groups symmetrically arranged in the circumferential direction of the outer rotor; or it may be that the mounting studs 511 and the third through holes include four groups symmetrically arranged in the circumferential direction of the outer rotor, etc.; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and should all fall within the protection scope of the present application.

[0047] The air conditioner (not shown in the figure) provided in the embodiment of the present application includes the ceiling air conditioner described in any of the above embodiments.

[0048] This air conditioner has all the advantages of the ceiling air conditioner provided by any of the above embodiments, which will not be described in detail here.

[0049] To sum up, in the ceiling machine provided in the embodiment of the present application, when removing the wind wheel, it is necessary to remove the air guide ring in advance, but not the electric control box in advance, and when the wind wheel is about to be removed from the motor, the wind wheel is removed in a tilted state. Since the avoidance groove on the inner bottom surface of the chassis will avoid the end of the wind wheel adjacent to the bottom wall of the chassis, the inclination angle of the wind wheel will be increased, which is more conducive to removing the wind wheel from the motor in a tilted state and removing it from the mounting hole in a tilted state. Correspondingly, the required size of the mounting hole is also smaller. Therefore, the maintenance process of the ceiling machine with this scheme is simpler to operate, less difficult to operate, and the strength of the water tray is higher.

[0050] Furthermore, the electric control box cooperates with the wall of the avoidance gap, and the air guide ring is pre-positioned during the installation process of the air guide ring, so the assembly speed of the air guide ring on the water receiving tray is faster.
