Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a nested motor housing. Background Art

[0002] The air conditioning motor plays a vital role in the air conditioning system. The fan motor of the indoor unit is responsible for driving the fan blades to rotate, thereby generating airflow, sucking the indoor air into the air conditioner and adjusting the temperature through the heat exchanger (evaporator or condenser), and then blowing the conditioned air out to achieve indoor temperature regulation and air circulation. During the cooling or heating process of the air conditioner, the motor-driven fan not only helps air circulation, but also promotes the efficiency of heat exchange. In the cooling mode, the fan of the indoor unit helps blow the indoor air through the evaporator, so that the refrigerant on the evaporator absorbs the heat in the air to achieve a cooling effect; in the heating mode, it helps blow the hot air out to achieve indoor temperature increase. The motors in modern air conditioning systems often have variable speed and wind direction adjustment functions. Users can adjust the wind speed and wind direction as needed to achieve a more comfortable indoor environment.

[0003] When the motor is installed in the air conditioner, it is necessary to fix the motor inside the air conditioner. Generally, when fixing the motor, in order to be more flexible, the motor of the air conditioner generally adopts a more compact structure. When installing the air conditioner motor, it is in contact with the main body of the air conditioner, and the gap is reduced as much as possible to make the structure compact, and the air conditioner can be minimized. However, the compact structure will affect the heat dissipation effect. If the heat cannot be dissipated in time, the internal temperature of the motor will be too high, which may cause serious consequences such as winding burning and bearing damage, affecting the normal operation and service life of the motor. In addition, the operation of the motor in a high temperature environment will increase the winding resistance and core loss, resulting in increased energy consumption. Based on this, the heat dissipation of the motor is extremely important. When installing a compact motor, the most compact case is that a cavity for installing the motor is left in the air conditioner, and then the motor is installed inside it, and the outer wall of the motor is in contact with the inside of the air conditioner to achieve the most compact state. Based on this, partial improvements to the motor are proposed. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8 The present invention provides a technical solution: the nested design allows the motor rotor, stator, guide rail, bearing and other components to be tightly combined to form an integral structure. The nested design makes the motor structure more compact and the volume is greatly reduced. This is particularly important for air-conditioning equipment, because the compact structure helps to save installation space, making the air-conditioning equipment more flexible and easy to install. The motor can be embedded in other components of the air-conditioning, thereby further reducing the overall volume and occupied space. Based on this, a nested motor housing is proposed, including a motor housing 1, an end cover 2 and an end cover 3. The end cover 2 and the end cover 3 are respectively installed at both ends of the motor housing 1 to form a part of the air-conditioning motor, which is also an improved part of the air-conditioning motor. The outer side of the motor housing 1 is installed with an external support frame 4 for outward support. When the external support frame 4 is supported, there is a gap between it and the outer wall of the motor housing 1 for heat dissipation. Through the external support frame 4, the outer side of the motor housing 1 can expand outward, and the diameter of the motor housing 1 is increased, thereby realizing the nested installation of the motor housing 1, and the external support frame 4 directly supports the outside to limit the motor housing 1 to prevent the motor housing 1 from generating vibration;

[0032] The end of the motor housing 1 is also provided with an induced draft mechanism 5 for heat dissipation. The induced draft mechanism 5 has an impeller 52 for driving the movement of gas. The generated gas moves from the gap between the outer support frame 4 and the motor housing 1. During the movement of the air-conditioning motor, heat is generated. However, it is still difficult to make the air flow with only the effect of the gap. The air-conditioning material is generally composed of plastic. The internal heat dissipation effect of the plastic air-conditioning is worse than that of the metal material. Therefore, the motor housing 1 is surrounded by plastic, the gas does not circulate, and the heat dissipation is also greatly affected. The induced draft mechanism 5 is provided to increase the fluidity of the gas and improve the heat dissipation effect.

[0033] The outer wall of the motor housing 1 is integrally formed with a recessed frame 11 recessed inwardly. The recessed frame 11 of the motor housing 1 is used to increase the area of ​​the motor housing 1. After the area is increased, the heat dissipation area is also increased. The recessed frame 11 extends along the axis of the motor housing 1. The outer support frame 4 is arranged in the recessed frame 11. The outer support frame 4 includes an outer support plate 41 in the middle. The outer support plate 41 is embedded in the recessed frame 11. The two ends of the outer support plate 41 are respectively hinged with connecting plates 42. The outer ends of the two connecting plates 42 are Both ends are hinged with outer sliders 43, and the two outer sliders 43 are slidably installed in the recessed frame 11. The two outer sliders 43 approach each other to enable the outer support plate 41 to move outward for supporting the inner wall of the air conditioner. When the two outer sliders 43 slide, they approach each other, so that the middle outer support plate 41 and the connecting plates 42 at both ends are subjected to force, so that the connecting plates 42 are bent, and the outer support plate 41 moves outward. The outer support plate 41 moves in the vertical and lateral ranges to adjust the degree to which the outer support plate 41 extends outward.

[0034] A butt plate 47 is also provided inside the recessed frame 11, and a support spring 46 is fixed between the butt plate 47 and the outer support plate 41. The support spring 46 is used to give the outer support plate 41 a force to move outward. Under the action of the support spring 46, the outer support plate 41 can have an outward force, but under the action of the two outer sliding blocks 43, the outer support plate 41 can still be reset and move outward. The support spring 46 can perform elastic telescopic movement to ensure smooth operation of the outer support plate 41.

[0035] The inner side of the recessed frame 11 is also provided with an inner opening 12 extending along the recessed frame 11. The inner sides of the two outer sliding blocks 43 are integrally formed with extension ends 44, and the extension ends 44 extend inward from the inner opening 12. The interior of the motor housing 1 is provided with a drive shaft 45 passing through the two extension ends 44. The drive shaft 45 is threadedly connected to the extension ends 44. The threads on the drive shaft 45 are bidirectionally arranged. The drive shaft 45 is rotated to make the two outer sliding blocks 43 approach each other. By rotating the drive shaft 45, the two outer sliding blocks 43 are brought close to each other, and the movement of the outer support frame 4 can be operated from the outer end of the air-conditioning motor, which is convenient for adjustment.

[0036] In order to achieve that multiple groups of external support frames 4 can all move and move outward at the same distance, one end of the driving shaft 45 passes through the end cover 23, and a gear body 1 48 is fixed to its passing end. Multiple groups of external support frames 4 are provided on the outside of the motor housing 1. The multiple groups of external support frames 4 are distributed in a circle. Gear body 2 49 is rotatably installed on the outer side of the end cover 23. Gear body 2 49 meshes with gear body 1 48 in the multiple groups of external support frames 4, so that each group of external support frames 4 expands outward at the same distance. By rotating the set gear body 2 49, the gear body 2 49 drives the gear body 1 48 meshing with it to rotate. On this basis, the synchronous movement of multiple groups of external support frames 4 is achieved.

[0037] The outer end of the end cover 2 3 is also covered with an outer cover 402, and an arc cavity 403 coaxial with the gear body 2 49 is opened on the outer cover 402, and a toggle end 401 fixed to the gear body 2 49 is provided in the arc cavity 403. Under the action of the outer cover 402, dirt is prevented from entering the gear body 1 48 and the gear body 2 49, avoiding jamming.

[0038] The end cover 2 is hollow, and the impeller 52 is arranged inside the end cover 2, and the impeller 52 is fixedly sleeved with the rotating shaft of the motor, and an inner baffle 51 is clamped between the end cover 2 and the motor housing 1, and the end cover 2 and the inner baffle 51 are fixed to the motor housing 1 by bolts, and the impeller 52 is located inside the motor housing 1, and is used to drive the gas to move;

[0039] An air outlet 55 is provided on the outside of the motor housing 1, and an inclined guide pipe 54 is fixed to the outside of the inner baffle 51. One end of the guide pipe 54 is connected to the inside of the end cover 2, and the other end is connected to the air outlet 55.

[0040] An air inlet 53 communicating with the interior of the end cover 2 is provided on the outer side of the end cover 2. Under the action of the impeller 52, the gas can enter from the air inlet 53 and move out from the air outlet 55, thereby realizing the movement of the gas.

[0041] The air outlet 55 is arranged at an angle, with its inclined inner end facing the outer side of one end of the motor housing 1. The function of the inclined air outlet 55 is to allow the gas moving outward from the air outlet 55 to enter the gap between the outer sides of the motor housing 1 and move outward, so that the gas continuously flushes the motor housing 1.

[0042] Working principle of the present invention: As one of the core components of the air-conditioning system, the installation method of the air-conditioning motor has an important impact on the overall performance and operating efficiency of the air-conditioning. Nested installation is a way to install the air-conditioning motor. Nested installation makes more efficient use of the space between the motor and other components of the air-conditioning system, thereby reducing the overall volume and floor space of the air-conditioning. This compact structural design helps to improve the overall aesthetics of the air-conditioning system and makes it easier to integrate into various indoor environments. Nested installation helps to reduce vibration and noise during motor operation, and can more effectively isolate and reduce the impact of motor vibration on other components of the air-conditioning system, thereby improving the stability and durability of the system.

[0043] However, after installation, the air-conditioning motor is wrapped around, and the heat dissipation will be greatly affected. Based on this, an outer support frame 4 is set, and the toggle end 401 is turned, the gear body 49 rotates, and multiple groups of drive shafts 45 also rotate. The function of the drive shaft 45 is to drive the two outer sliders 43 in one group to approach each other, and under the action of the support spring 46, the outer support plate 41 moves outward, and the outer support plate 41 supports the inner wall of the air conditioner outward. When the air-conditioning motor is installed in a nested manner, a certain gap needs to be left between the outer wall of the air-conditioning motor and the nesting space for the outer support plate 41 to support and fix the air-conditioning motor, and the outer side of the motor housing 1 has a gap for the heat dissipation of the air-conditioning motor, which is convenient for fixing the air-conditioning motor and is also suitable for nesting in different air conditioners, which is also convenient for the heat dissipation of the air-conditioning motor.

[0044] During the rotation of gear body 2 49, gear body 2 49 can drive multiple groups of external support frames 4 to move, so that the outer support plates 41 of multiple groups of external support frames 4 move outward by the same distance, so that the air-conditioning motor coincides with the axis of the nested hole, so that the air-conditioning motor is not subject to shear force and is more stable.

[0045] When the air-conditioning motor is in operation, the motor shaft drives the impeller 52 to rotate, and the impeller 52 drives the movement of the gas, so that air enters the air inlet 53, and the gas moves outward from the air outlet 55 through the guide tube 54. The gas enters the gap on the outside of the motor housing 1 and takes away the heat of the motor housing 1. When the gas passes through the gap, the flow rate of the gas increases due to the small width of the gap. The high-speed flowing gas can more effectively take away the heat of the outer wall of the motor housing 1, thereby reducing its temperature. In addition, the gas passes through the outer wall of the motor housing 1 instead of moving from the inside of the motor housing 1, which reduces the entry of stains into the inside of the motor housing 1 and extends the service life of the air-conditioning motor.
