The utility model provides a wall-mounted air conditioner indoor unit.
In the embodiment of the present utility model, as shown in fig. 1, the wall-mounted air conditioner indoor unit includes a chassis, a cross-flow wind wheel 100 and an outer rotor motor 200, wherein the cross-flow wind wheel 100 is connected to the chassis, the outer rotor motor 200 includes a rotor 210 and a stator 220, and the outer rotor motor 200 is connected to the cross-flow wind wheel 100.
Specifically, considering that the present solution is a wall-mounted air conditioning indoor unit, the length of the cross-flow wind wheel 100 extends in the axial direction thereof in the wall-mounted air conditioning indoor unit. The wall-mounted air conditioner indoor unit includes a chassis (not shown), which is a conventional structure of the wall-mounted air conditioner indoor unit and is used for installing the cross-flow wind wheel 100 and other components inside the wall-mounted air conditioner indoor unit, and the cross-flow wind wheel 100 and the other components are generally installed on the chassis in a screwed installation manner, and of course, other installation manners such as riveting, cementing and the like can be adopted, and the wall-mounted air conditioner indoor unit is not particularly limited herein. The outer rotor motor 200 may be directly connected to the chassis or indirectly connected to the chassis, which is not particularly limited herein.
The outer rotor motor 200 of the present embodiment is specifically configured as an outer rotor 210 brushless dc motor, where the outer rotor motor 200 includes a rotor 210 and a stator 220, where the rotor 210 is disposed around an outer ring of the stator 220, the outer rotor motor 200 further includes a motor shaft 230, and the outer rotor motor 200 is connected to the cross-flow wind wheel 100 through the motor shaft 230.
According to the technical scheme, the inner rotor motor is replaced by the outer rotor motor 200, and the motor is not required to be fixed through the rubber sleeve, so that the axial space occupied by the indoor fan can be reduced.
In an embodiment, referring to fig. 2, the wall-mounted indoor unit of the air conditioner further includes a motor bracket 300, the motor bracket 300 is connected to the chassis, and the stator 220 is mounted on the motor bracket 300.
Specifically, the stator 220 is connected to the chassis through the motor bracket 300, wherein the connection mode of the motor bracket 300 and the chassis may be screw connection, riveting, gluing or the like, and the connection mode of the motor bracket 300 and the chassis is not specifically limited. The outer rotor motor 200 is mounted on the motor bracket 300, wherein the mounting mode can be through screw connection or clamping connection.
In a preferred embodiment, referring to fig. 2, 3 and 7, a first gap 240 is formed between the rotor 210 and the stator 220, and the motor bracket 300 includes a first annular portion 310, and the first annular portion 310 is disposed around the outer side of the outer rotor motor 200 for shielding the first gap 240.
It should be noted that, the first gap 240 is formed between the rotor 210 and the stator 220 and is in communication with the outside, and the first gap 240 is an air gap, which is used for exchanging electromechanical energy, and considering that, if the air gap is directly formed at the outer surface of the motor, water or dust in the indoor air duct can easily enter the air gap, so that the motor support 300 extends towards the through-flow wind wheel 100 to form a first annular portion 310, wherein the first annular portion 310 is disposed around the outer side of the outer rotor motor 200, and shields the first gap 240, so as to prevent water or dust from entering the air gap directly. Wherein, a certain distance should be provided between the first annular portion 310 and the outer rotor motor 200 for ensuring the normal operation of the motor. In this embodiment, the first annular portion 310 extends toward the through-flow wind wheel 100 after covering the first gap 240, so that the first annular portion 310 is further raised for water or dust protection.
Further, referring to fig. 2, 3 and 7, the bracket further includes a second annular portion 320, the second annular portion 320 is disposed around the outer side of the first annular portion 310, and an annular groove 330 is formed between the first annular portion 310 and the second annular portion 320.
Referring to fig. 3, the direction indicated by the black arrow in fig. 3 is the flowing direction of the water or dust after the first annular portion 310 is added, it is obvious that the flow path through which the water or dust enters the first gap 240 is increased, the flow path is increased, the difficulty of the water or dust entering the first gap 240 is increased, and the entering amount of the water or dust in the first gap 240 is greatly reduced after the first annular portion 310 shields the first gap 240.
Specifically, considering that the thickness of the first annular portion 310 is thinner and the strength is worse, if the first annular portion 310 is deformed and bent, collision may occur with the outer rotor motor 200, and normal operation of the outer rotor motor 200 is affected, so that the second annular portion 320 is disposed around the outer side of the first annular portion 310, and the second annular portion 320 is used for reinforcing the first annular structure, so that the first annular portion 310 is not easy to deform. In addition, an annular groove 330 is formed between the first annular portion 310 and the second annular portion 320, and the annular groove 330 can be used to receive part of water or dust, reduce the water or dust flowing into the space between the first annular portion 310 and the outer rotor motor 200, and prevent the outer rotor motor 200 from being polluted by the external environment.
Optionally, referring to fig. 4 to 5, the cross-flow wind wheel 100 includes end caps 110 disposed at two ends of the cross-flow wind wheel 100, a second gap 250 is provided between the end caps 110 and the rotor 210, one end of the cross-flow wind wheel 100, which is close to the outer rotor motor 200, is provided with a flanging ring 120, and the flanging ring 120 is circumferentially disposed outside the second gap 250, for shielding the second gap 250.
It should be noted that, considering that the external rotor motor 200 may vibrate during operation, the external rotor motor 200 generates an amplitude, and thus, a certain distance between the rotor 210 of the external rotor motor 200 and the end cover 110 is required, and the distance is set as the second gap 250. The presence of the second gap 250 causes water or dust to easily enter the first gap 240, and therefore, the flange ring 120 is disposed at the end of the cross-flow wind wheel 100 near the outer rotor motor 200, and the flange ring 120 is used for shielding the second gap 250 to prevent water or dust from entering the first gap 240 through the second gap 250. In this embodiment, the flanging ring 120 completely covers the second gap 250, which has a better protection effect, and of course, the flanging ring 120 may also partially cover the second gap 250, which also has the protection effect described above. In this embodiment, the flanging ring 120 not only covers the second gap 250, but also covers a part of the first annular portion 310, so as to further improve the protection effect for water or dust entering the first gap 240.
Specifically, a second gap 250 is formed between the end cover 110 and the rotor 210, and in one embodiment, referring to fig. 4, the second gap 250 is set to D, where D is 3mm and D is 7mm.
In addition, when the inner rotor motor is generally matched with the cross-flow wind wheel 100, the inner rotor motor needs to be fixed and protected by a rubber sleeve, wherein the thickness of the rubber sleeve is thicker, the distance between the motor and the end cover 110 is increased, and the axial space of the fan is further increased. Considering that, when the outer rotor motor 200 is in operation, the outer rotor 210 rotates, the rotor 210 may be damaged by collision due to the fact that the outer rotor motor 200 is too close to the cross-flow wind wheel 100, the second gap 250 is set to be not smaller than 3mm, the distance between the second gap 250 is reduced relative to the inner rotor motor by using the outer rotor motor 200, the axial space is saved, and the second gap 250 is set to be not larger than 7mm. In addition, since the shape of the end cap 110 is set to be a circular shape with a concave middle portion in this embodiment, the size of the second gap 250 is not fixed at different positions, and the size of the second gap 250 is set between 3mm and 7mm.
In an embodiment, referring to fig. 6, the wall-mounted air conditioner indoor unit further includes a vibration damping pad 400, and the vibration damping pad 400 is located between the outer rotor motor 200 and the motor bracket 300.
Specifically, the vibration damping pad 400 is used to reduce the vibration amplitude of the external rotor motor 200 during operation, and the vibration damping pad 400 may be made of rubber, although other vibration damping materials may be used, and the vibration damping materials are not particularly limited herein. The number of the damper pads 400 may be one or more, and the damper pads 400 may be annular, columnar, or other irregular.
In one embodiment, referring to fig. 6, the number of the vibration-damping pads 400 is plural, and the vibration-damping pads 400 are separately arranged.
It should be noted that, when a plurality of vibration damping pads 400 are provided as one body, the vibration damping effect of the outer rotor motor 200 may be poor or the vibration damping may be uneven due to the limited mounting manner of the vibration damping pads 400, for example, a plurality of vibration damping pads 400 are disposed at one side of the outer rotor motor 200 and no vibration damping pad 400 is disposed at the other side. In view of this, the plurality of vibration-damping pads 400 are separately arranged, and the plurality of vibration-damping pads 400 are uniformly distributed, so that the uneven vibration-damping effect or uneven vibration-damping of the vibration-damping pads 400 is avoided, and of course, the solution of integrally arranging the plurality of vibration-damping pads 400 is also within the protection scope of the above embodiment. Note that, the number of the vibration damping pads 400 in the present embodiment is three, and the present utility model is not limited to this embodiment, and the number of the vibration damping pads 400 may be two, the number of the vibration damping pads 400 may be four, and the number of the vibration damping pads 400 may be more.
In one embodiment, referring to fig. 2, the length of the outer rotor motor 200 in the axial direction thereof is set to 40mm to 45mm.
Specifically, when the inner rotor motor is usually assembled with the cross-flow wind wheel 100, the inner rotor motor needs to be fixed and protected by a rubber sleeve, wherein the rubber sleeve has a larger thickness, which increases the distance between the motor and the end cover 110, and further increases the axial space of the fan. More specifically, in the present embodiment, the length of the outer rotor motor 200 in the axial direction is set to 43.5mm, and it is to be noted that the axial length of the outer rotor motor 200 is the distance from one end face to the other opposite end face of the outer rotor motor 200. Considering that the required indoor fan powers of different air conditioners are different, the length of the outer rotor motor 200 in the axial direction also has a certain gap, and in this way, the axial length of the outer rotor motor is set to be 40mm to 45mm, under the range, the indoor fan of the wall-mounted air conditioner indoor unit provided by the embodiment can be ensured to normally operate, and compared with the inner rotor motor with the same performance, the outer rotor motor 200 in the embodiment occupies smaller space in the axial direction.
The utility model also provides an air conditioner which comprises the wall-mounted air conditioner indoor unit, and the specific structure of the wall-mounted air conditioner indoor unit refers to the embodiment, and as the air conditioner adopts all the technical schemes of all the embodiments, the air conditioner at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted.
The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
