Description

Technical Field

[0001] This application relates to the technical field of air conditioners, and particularly to a fan assembly and an air conditioner. Background Art

[0002] The fan is an important part of the indoor unit of an air conditioner. Currently, the fan and the output shaft of the motor are usually fixed by screws. When repairing the motor, it is necessary to first remove the screws between the motor and the fan before the motor can be removed.

[0003] Since the position where the fan stops rotating is different after the indoor unit works, it cannot be guaranteed that the screws face the operator every time the fan stops, resulting in the operator having to rotate the fan to a position where the screws face the operator.

[0004] However, most of the fan is blocked by the evaporator, making it difficult to rotate the fan.

[0005] It should be noted that the information disclosed in the above background art is only used to enhance the understanding of the background of this application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0046] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0047] Combined with Figures 1-8 As shown, the embodiments of the present disclosure provide an indoor unit, including a panel assembly, a fan 20, and a motor 60.

[0048] The panel assembly defines a fan cavity; the fan 20 is disposed in the fan cavity; the output shaft 601 of the motor 60 is connected to the fan 20 through a connecting member 201 to be drivingly connected to the fan 20.

[0049] Wherein, as Figure 2 and Figure 3 shown, the panel assembly is provided with a quick-release groove 301, and the quick-release groove 301 is correspondingly arranged with the connecting member 201 so that a tool can take out the connecting member through the quick-release groove.

[0050] As Figure 4 shown, the fan 20 is disposed in the fan cavity. An end of the fan 20 is provided with a bushing 22. The output shaft 601 of the motor is inserted into the bushing 22, and the bushing 22 is connected to the output shaft 601 through the connecting member 201 to realize the driving of the fan 20 by the motor 60. Driven by the motor 60, the fan rotates, sucks air from the air inlet of the air duct and blows it out from the air outlet, realizing the normal refrigeration and heating of the air conditioner.

[0051] A connecting portion 21 is provided on the fan bushing 22, and a connecting and mating portion 602 is provided on the output shaft 601 of the motor. The connecting portion 21 and the connecting and mating portion 602 can be detachably connected through the connecting member 201. The connecting member 201 can be a screw or a pin shaft. Taking the connecting member 201 as a screw as an example, the connecting portion 21 is a first screw hole, and the connecting and mating portion 602 is the outer surface of the output shaft 601. After the screw passes through the first screw hole, it abuts against the connecting and mating portion 602 to realize the screw connection between the connecting portion 21 and the connecting and mating portion 602.

[0052] The disassembly tool is a tool used to disassemble the connecting member. Taking the connecting member 201 as a screw as an example, the disassembly tool can be a screwdriver or a wrench, etc.

[0053] The panel assembly is provided with a quick-release groove 301, and the quick-release groove 301 is correspondingly arranged with the connecting member 201. When disassembling the motor 60, the disassembly tool can extend into the quick-release groove 301 to disassemble the connecting member 201 between the fan 20 and the output shaft 601 of the motor, so that the motor 60 is disconnected from the fan 20, thereby quickly taking out the motor 60, reducing the disassembly difficulty of the motor 60, and improving the disassembly efficiency of the motor 60.

[0054] Optionally, as Figure 6 shown, the indoor unit further includes an evaporator 40, and the evaporator 40 is disposed between the panel assembly and the fan 20; the panel assembly includes a panel 30 and a water receiving tray 50. The water receiving tray 50 is disposed between the panel 30 and the evaporator 40; the panel 30 is provided with a first quick-release groove 3011, and the water receiving tray 50 is provided with a second quick-release groove 3012 corresponding to and communicating with the first quick-release groove 3011. Among them, the quick-release groove 301 includes the first quick-release groove 3011 and the second quick-release groove 3012.

[0055] The first quick-release slot 3011 communicates with the second quick-release slot 3012. When disassembling the motor 60, the disassembly tool passes through the first quick-release slot 3011 and the second quick-release slot 3012 in sequence to disassemble the connecting piece 201, thereby removing the motor 60.

[0056] The first quick-release slot 3011 and the second quick-release slot 3012 are respectively arranged on the panel 30 and the water receiving tray 50, avoiding interference between the panel 30 or the water receiving tray 50 and the disassembly tool, so that the disassembly tool can contact the connecting piece 201 and disassemble the connecting piece.

[0057] The first quick-release slot 3011 and the second quick-release slot 3012 correspond to each other, which means that in the orthographic projection of the water receiving tray 50 on the panel 30, the second quick-release slot 3012 and the first quick-release slot 3011 at least partially overlap, for example, completely overlap, facilitating the disassembly tool to be inserted into the first quick-release slot 3011 and the second quick-release slot 3012.

[0058] The shapes and sizes of the first quick-release slot 3011 and the second quick-release slot 3012 are respectively adapted to each other. For example, the shapes of the first quick-release slot 3011 and the second quick-release slot 3012 are the same, and the sizes are the same.

[0059] Optionally, as Figure 1 shown, the panel assembly includes a first sub-panel assembly 311 and a second sub-panel assembly 312.

[0060] The first sub-panel assembly 311 is arranged corresponding to the fan 20 and defines a fan cavity; the second sub-panel assembly 312 is arranged corresponding to the motor 60 and defines a motor cavity. The motor 60 is arranged in the motor cavity. The second sub-panel assembly 312 is provided with a maintenance port 313 corresponding to the motor cavity. The quick-release slot 301 is arranged between the first sub-panel assembly 311 and the second sub-panel assembly 312.

[0061] The maintenance port 313 is arranged corresponding to the motor cavity, so that the motor 60 can be taken out through the maintenance port 313. Or, when it is not necessary to take out the motor 60, the motor 60 can be repaired through the maintenance port 313.

[0062] The connecting piece 201 connects the bushing 22 of the fan 20 and the output shaft 601 of the motor 60. The fan 20 is located in the fan cavity, that is, arranged corresponding to the first sub-panel assembly 311, and the motor 60 is arranged in the motor cavity, that is, arranged corresponding to the second sub-panel assembly 312. Therefore, the connecting piece 201 is arranged corresponding to the connection between the first sub-panel assembly 311 and the second sub-panel assembly 312. The quick-release slot 301 is arranged at the connection between the first sub-panel and the second sub-panel, so that the position of the quick-release slot 301 corresponds to the position of the connecting piece 201, and thus the disassembly tool enters through the quick-release slot 301 to disassemble the connecting piece.

[0063] Optionally, as Figure 2As shown, the quick-release slot 301 is provided on the side wall of the maintenance opening 313.

[0064] The quick-release slot 301 is provided on the side wall of the maintenance opening 313, that is, the maintenance opening 313 is communicated with the quick-release slot 301. The maintenance opening 313 and the quick-release slot 301 can continuously form a larger opening. On the one hand, the operator can see a larger area in the fan cavity and / or the motor cavity through this opening. On the other hand, when the disassembly tool is inserted into the quick-release slot, a part of the disassembly tool can be located in the maintenance opening 313, so as to reduce the opening area of the quick-release slot 301 and avoid a large loss of the strength of the panel assembly caused by the opening of the quick-release slot 301.

[0065] The maintenance opening 313 is rectangular, as Figure 2 shown, including a first side wall 3131 and a second side wall 3132 which are oppositely arranged. The first side wall 3131 and the second side wall 3132 are arranged in sequence along the direction from the first sub-panel assembly 311 to the second sub-panel assembly 312. The quick-release slot 301 is provided on the first side wall 3131 so that the quick-release slot 301 corresponds to the connecting member 201.

[0066] Combined with Figure 2 shown, along the direction close to the maintenance opening 313, the opening area of the quick-release slot 301 increases to form a flared structure.

[0067] The opening size of the end of the quick-release slot 301 close to the maintenance opening 313 is larger than the opening size of the end of the quick-release slot 301 far from the maintenance opening 313. The end of the quick-release slot 301 close to the maintenance opening 313 is closer to the motor 60, and the opening here is larger, which can facilitate the maintenance or removal of the motor 60. At the same time, the opening size of the end of the quick-release slot 301 far from the maintenance opening 313 is smaller, avoiding the influence of the too large opening size of the quick-release slot 301 on the strength of the connection between the first sub-panel assembly 311 and the second sub-panel assembly 312.

[0068] As Figure 7 shown, the groove wall of the quick-release slot 301 includes a first groove wall 3013, a second groove wall 3014 and a third groove wall 3015. The first groove wall 3013 and the second groove wall 3014 are connected, and the second groove wall 3014 and the third groove wall 3015 are connected. The second groove wall 3014 and the third groove wall 3015 are oppositely arranged. An angle greater than 90 degrees is formed between the first groove wall 3013 and the second groove wall 3014, and between the second groove wall 3014 and the third groove wall 3015, so that along the direction close to the maintenance opening 313, the opening area of the quick-release slot 301 increases and forms a flared structure, which can extend the disassembly tool to facilitate the disassembly of the motor 60.

[0069] Optionally, as Figure 1As shown, the indoor unit of the air conditioner further includes a maintenance board 70. The maintenance board 70 includes a board body 701 and an extension edge 702 provided at the edge of the board body. The board body 701 covers the maintenance opening 313, and the extension edge 702 covers the quick-release groove 301.

[0070] By covering the quick-release groove 301 with the extension edge 702, the quick-release groove 301 is blocked, preventing the quick-release groove 301 from affecting the appearance of the panel assembly.

[0071] The maintenance board 70 is detachably connected to the panel assembly, such as by snap connection or screw connection, to facilitate removing the maintenance board 70 for repairing the motor 60. Alternatively, the maintenance board 70 is movably connected to the panel assembly, such as by rotational connection or sliding connection, to facilitate the maintenance board 70 to open the maintenance opening 313. Or, one end of the maintenance board 70 is detachably connected to the panel assembly, and the other end is movably connected to the panel assembly.

[0072] Optionally, as Figure 6 shown, the indoor unit of the air conditioner further includes a skeleton 80 and a gland 101.

[0073] The skeleton 80 is disposed opposite to the panel assembly and together with the panel assembly encloses a fan cavity; the gland 101 covers the motor 60 and is detachably or movably connected to the skeleton 80; wherein, the orthographic projection of the gland 80 on the panel assembly at least partially coincides with the quick-release groove 301.

[0074] The skeleton 80 is disposed on one side of the fan 20, and the panel assembly is disposed on the other side of the fan 20. And the skeleton 80 and the panel assembly together enclose a motor cavity.

[0075] The gland 101 is disposed on the motor 60 and is detachably or movably connected to the skeleton 80. On the one hand, the motor 60 is positioned on the skeleton through the gland 101. On the other hand, when the motor 60 needs to be disassembled, in the case where the gland 101 is detachably connected to the skeleton 60, the gland 101 can be removed from the skeleton 80. When the gland 101 is movably connected to the skeleton 80, the gland 101 can be opened to expose the motor 60.

[0076] The detachable connection can be screw connection. For example, the gland 101 is provided with a third screw hole, and the skeleton 80 is provided with a fourth screw hole, and the screw passes through the third screw hole and the fourth screw hole. The number of the third screw holes is multiple, and the multiple screw holes are respectively located on opposite sides of the gland 101. For example, two third screw holes are provided on one side of the gland 101, and two third screw holes are provided on the other side of the gland 101. The number of the fourth screw holes is equal to the number of the third screw holes and corresponds to each other one by one.

[0077] The screw connection may be a rotational connection or a sliding connection. Taking the rotational connection as an example, the pressure cover 101 is rotated to enable the pressure cover 101 to move between a position where it covers the motor 60 and a position where it does not cover the motor 60 .

[0078] The orthographic projection of the pressure cover 101 on the panel assembly at least partially overlaps with the quick-release slot 301 , so that the connection between the pressure cover 101 and the frame 80 can be seen through the quick-release slot 301 , thereby facilitating separation of the pressure cover 101 from the frame 80 .

[0079] Optionally, the orthographic projection of the connecting member 201 on the panel assembly at least partially overlaps with the quick-release slot 301 .

[0080] This makes it easy to remove the connector 201 after the disassembly tool is inserted into the quick-release slot 301 .

[0081] Alternatively, the orthographic projection of the connecting member 201 on the panel assembly does not overlap with the quick-release slot 301 .

[0082] When the position of the connector 201 and the position of the quick release slot 301 are determined, the orthographic projection of the connector 201 on the panel assembly does not overlap with the quick release slot 301, which can reduce the opening area of ​​the quick release slot 301, thereby preventing the setting of the quick release slot 301 from having a significant impact on the strength of the panel assembly. In this case, when disassembling the connector 201, the disassembly tool is tilted toward the connector 201 in the quick release slot 301, so that the disassembly tool can touch the connector 201.

[0083] Alternatively, if Figure 8 As shown, a shaft sleeve 22 is protruding from the surface of the fan 20 facing the motor 60 , the motor shaft 601 is inserted into the shaft sleeve 22 , and the connecting member 201 connects the shaft sleeve 22 and the motor shaft 601 .

[0084] Compared with the shaft sleeve 22 being formed by a depression on the surface of the fan 20 facing the motor 60, the shaft sleeve 22 in the present application is arranged on the surface of the fan 20 facing the motor 60 and protrudes from the surface. In this way, the connecting member 201 and the evaporator 40 can be staggered to prevent the evaporator 40 from blocking the connecting member 201, thereby eliminating the need to disassemble the evaporator 40 when disassembling the connecting member 201.

[0085] The indoor unit further includes a motor base 102 , which abuts against the end surface of the motor 60 facing away from the fan 20 . The motor base 102 is connected to the frame 80 , thereby further realizing the positioning of the motor 60 relative to the frame 80 .

[0086] The motor seat 102 is detachably or movably connected to the frame 80. When the motor 60 needs to be removed, the motor seat 102 is removed from the frame 80 or the position of the motor seat 102 is changed relative to the frame 80 so that the motor seat 102 does not interfere with the motor 60, thereby removing the motor 60.

[0087] The indoor unit further includes an electric control box body, which is arranged on the side of the motor 60 facing the panel assembly. The electric control box body includes an electric control box cover and an electric control box body. Taking the example that both the gland 101 and the motor base 102 are screwed to the skeleton 80, when the motor 60 needs to be disassembled, first open the maintenance board 70 to expose the maintenance port 313, then open the electric control box cover and the terminal block cover, pull out the terminals and remove the connection wire, then remove the electric control box body, insert a screwdriver through the maintenance port 313 to remove the gland 101 and the motor base 102, insert a disassembly tool through the quick-release slot 301 to take out the connecting piece 201, and thus take out the motor 60.

[0088] Optionally, as Figure 8 shown, the outer surface of the shaft sleeve 22 is provided with a concavo-convex structure.

[0089] The concavo-convex structure can increase the friction force on the outer surface of the shaft sleeve 22, avoiding slipping when using tools or manually rotating the shaft sleeve 22. When disassembling and repairing the motor 60, the shaft sleeve 22 can be easily rotated by means of tools or manually, so that the fan 20 rotates to the position where the connecting piece 201 faces the operator, so that the operator can use a disassembly tool to disassemble the connecting piece 201, and then disassemble the motor 60, which is convenient for disassembling the motor 60 and improves the efficiency of disassembling the motor 60.

[0090] Optionally, the concavo-convex structure is arranged on the outer surface of the side wall of the shaft sleeve 22.

[0091] The shaft sleeve 22 is connected to the output shaft 601 of the fan 20 and the motor 60. When the fan 20 and the motor 60 need to be disassembled, after the connecting piece 201 is disassembled, hold the shaft sleeve 22 of the fan 20 by hand and rotate the shaft sleeve 22 until the connecting piece 201 faces the operator to disassemble the connecting piece 201. When disassembling the connecting piece 201, the operator holds the outer surface of the side wall of the shaft sleeve 22 and rotates the shaft sleeve 22, which is a conventional operation of the operator. The concavo-convex structure is arranged on the outer surface of the side wall of the shaft sleeve 22, increasing the friction force on the outer surface of the side wall of the shaft sleeve 22 and improving the stability of the operator holding the outer surface of the side wall of the shaft sleeve 22, preventing slipping when rotating the shaft sleeve 22.

[0092] The inner surface of the side wall of the shaft sleeve 22 abuts against the outer surface of the output shaft 601 of the motor 60, and the concavo-convex structure is arranged on the outer surface of the side wall of the shaft sleeve 22.

[0093] Optionally, as Figure 8 shown, the outer surface of the side wall of the shaft sleeve 22 includes a platform section 222 and a non-platform section 223.

[0094] The non-platform section 223 is connected to the platform section 222 and is arranged in sequence along the circumferential direction of the shaft sleeve 22; wherein, the platform section 222 is connected to the output shaft 601 through the connecting piece 201, and the concavo-convex structure is arranged on the non-platform section 223.

[0095] The outer surface of the side wall of the bushing 22 is provided with a platform section 222, and the platform section 222 provides a platform for the setting of the connecting portion 21, facilitating the setting of the connecting portion 21. Moreover, the outer surface of the output shaft 601 corresponding to the platform section 222 is also in the shape of a platform, and the connecting member 201 abuts against this platform-shaped portion, which can increase the contact area between the connecting member 201 and the output shaft 601, increase the frictional force between the connecting member 201 and the output shaft 601, and realize the positioning of the bushing 22 relative to the output shaft 601.

[0096] The connecting member 201 is arranged on the platform section 222. The purpose of rotating the bushing 22 is to orient the connecting member 201 towards the operator, that is, to orient the platform section 222 towards the operator. Therefore, the concave-convex structure is arranged on the non-platform section 223.

[0097] Optionally, as Figure 8 shown, the concave-convex structure includes a rib 221 provided on the outer surface of the bushing 22.

[0098] The rib 221 can increase the friction coefficient of the outer surface of the bushing 22, enhance the frictional force for holding the bushing 22, and facilitate the rotation of the bushing 22. Moreover, the rib 221 can increase the strength of the bushing 22 and prevent the setting of the concave-convex structure from affecting the strength of the bushing 22.

[0099] Optionally, the rib 221 has a non-zero angle with the circumferential direction of the bushing 22, that is, the rib 221 does not extend along the circumferential direction of the bushing 22.

[0100] If the rib 221 extends along the circumferential direction of the bushing 22, it is not easy for the operator to hold the rib 222. Therefore, the rib 221 has a non-zero angle with the circumferential direction of the bushing 22, which is convenient for the operator to hold. Moreover, when the operator rotates the bushing 22, the extending direction of the rib 221 intersects with the direction in which the operator rotates the fan 20, making it more convenient to rotate the bushing 22.

[0101] Optionally, as Figure 8 shown, the rib 221 extends along the axial direction of the output shaft 601.

[0102] In this way, when holding the rib 221 to rotate the bushing 22, with the bushing 22 rotating the same angle, the displacement of the operator's hand is minimized, further improving the efficiency of disassembling the connecting member 201.

[0103] Optionally, the rib 221 can also include multiple sub-ribs, and the multiple sub-ribs are arranged at intervals along the axial direction of the output shaft 601.

[0104] The multiple sub-ribs are arranged at intervals along the axial direction of the output shaft 601. The multiple sub-ribs can also increase the friction coefficient of the outer surface of the bushing 22, so as to increase the frictional force and prevent slipping during the rotation of the bushing 22.

[0105] Combined withFigure 2 and Figure 3 As shown Figure 8 As shown, the number of the convex ribs is multiple, and the multiple convex ribs are sequentially arranged along the circumferential direction of the shaft sleeve 22.

[0106] By providing multiple convex ribs 221, an operator can hold multiple convex ribs 221 simultaneously, which increases the convenience of rotating the shaft sleeve 22. Or, when the shaft sleeve 22 rotates to different positions, the operator can hold the convex ribs 221 at different positions, which facilitates the operator to rotate the shaft sleeve 22.

[0107] As Figure 8 shown, the multiple convex ribs 221 form the shape of a gear.

[0108] The projections of two adjacent convex ribs 221 on the longitudinal section of the shaft sleeve 22 do not coincide at least partially.

[0109] This can reduce the area occupied by the convex ribs 221 on the outer surface of the shaft sleeve 22 and reduce the influence of the convex ribs 221 on the shaft sleeve 22.
