Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a vertical air conditioner indoor unit. Background Technology

[0002] A floor-standing air conditioner indoor unit is a device that regulates indoor temperature and improves user comfort. Floor-standing air conditioner indoor units typically include a cross-flow fan. As the fan rotates, it blows heated air from inside the unit into the room, thus achieving the purpose of heating or cooling and regulating indoor temperature. However, the cross-flow fan in this technology experiences significant friction during rotation, making it difficult to increase its speed and also resulting in considerable noise. Utility Model Content

[0003] This application discloses a vertical air conditioner indoor unit that can easily increase the speed of the first cross-flow fan, reduce the operating noise of the first cross-flow fan, and avoid the first cross-flow fan from moving up and down.

[0004] To achieve the above objectives, this application discloses a vertical air conditioner indoor unit, comprising: An air conditioner housing, wherein an air inlet and an air outlet are provided on the air conditioner housing; A first cross-flow fan is rotatably disposed inside the air conditioner housing and extends along the height direction of the air conditioner housing. A heat exchanger is disposed inside the air conditioner housing. When the first cross-flow fan rotates, it can draw indoor air into the air conditioner housing through the air inlet. The heat exchanger is used to heat treat the air. The first cross-flow fan is also used to blow the heat-treated air out through the air outlet when it rotates. A first drive module is connected to the upper end of the first cross-flow fan; A first drive cover is disposed on the first drive module and connected to the air conditioner housing; The first driving module includes: The stator is connected to the first drive cover, and the stator has a first central hole that penetrates the stator along the height direction. The stator also has a coil. The rotor is spaced around the stator at intervals along the axis of the first central hole. The rotor is connected to the upper end of the first cross-flow fan. When the coil is energized, it can drive the rotor to rotate around the axis. A first rotating shaft is connected to the first cross-flow fan and is located inside the first central hole; The vertical air conditioner indoor unit also includes: A bearing module is located between the stator and the first drive cover along the height direction. The bearing module includes a first bearing, which is rotatably sleeved on a first rotating shaft. The first limiting member is disposed on the first rotating shaft and abuts against the lower end of the first bearing; The second limiting member is disposed on the first rotating shaft and abuts against the upper end of the first bearing.

[0005] Because the rotor is spaced around the stator around the axis, and because the coil can drive the rotor to align with the center of the axis when energized, there is no contact point between the rotor and the stator. In layman's terms, the rotor is suspended relative to the stator. This reduces the friction between the rotor and the stator, and thus makes it easier to increase the speed of the first cross-flow fan while reducing the operating noise of the first cross-flow fan.

[0006] In addition, when the first limiting member is disposed on the first rotating shaft and abuts against the lower end of the first bearing, and the second limiting member is disposed on the first rotating shaft and abuts against the upper end of the first bearing, the first limiting member, the first bearing and the second limiting member work together to make the first rotating shaft only rotate around the axis and unable to move up and down along the above-mentioned height direction.

[0007] When the first shaft cannot move up and down along the aforementioned height direction, since the first shaft is connected to the first cross-flow fan, the first cross-flow fan will not be able to move up and down. The bearing module can bear the weight of the first cross-flow fan through the first shaft, thereby preventing the first cross-flow fan from falling abnormally downward. This can prevent the rotor from moving downward relative to the stator due to the first cross-flow fan falling abnormally downward, thus preventing the first drive module from failing.

[0008] Furthermore, since both the bearing module and the first drive module are located at the top of the first cross-flow fan, and the bearing module can bear the weight of the first cross-flow fan, that is, the first drive module that drives the first cross-flow fan to rotate and the bearing module that bears the weight of the first cross-flow fan are both integrated at the top of the first cross-flow fan. In this way, compared with setting the structure that drives the first cross-flow fan to rotate and the structure that bears the weight of the first cross-flow fan at the two ends of the first cross-flow fan respectively, when the first cross-flow fan expands and undergoes a slight deformation, the first cross-flow fan can release the expansion size downward, thereby ensuring that the rotation of the first cross-flow fan is more stable.

[0009] Optionally, the first bearing includes: An inner ring component is sleeved on the first rotating shaft, a first limiting component abuts against the lower end of the inner ring component, and a second limiting component abuts against the upper end of the inner ring component. An outer ring component is rotatably fitted around the periphery of the inner ring component and is positioned between the stator and the first drive cover along the height direction.

[0010] Optionally, a countersunk hole coaxial with the axis is provided on the upper surface of the stator, and the outer ring is located in the countersunk hole; Along the height direction, the outer ring is positioned between the bottom of the first drive cover and the countersunk hole.

[0011] Optionally, one of the first limiting member and the second limiting member is detachably disposed on the first rotating shaft.

[0012] Optionally, the first limiting member is fixedly installed, while the second limiting member is detachably installed.

[0013] Optionally, the bearing module further includes: A first bearing bracket is sleeved around the outer ring component and is positioned between the stator and the first drive cover along the height direction.

[0014] Optionally, the first bearing support includes: A first surrounding portion surrounds the peripheral wall of the outer ring member; The first bottom adhesive portion is disposed at the lower end of the first surrounding portion, and the upper surface of the first bottom adhesive portion abuts against the lower end of the outer ring member.

[0015] Optionally, the bearing module further includes: A first buffer member is sleeved around the periphery of the first surrounding portion, and the first buffer member is positioned between the stator and the first drive cover along the height direction.

[0016] Optionally, along the height direction, the thickness of the first limiting member is greater than the thickness of the second limiting member.

[0017] Optionally, the vertical air conditioner indoor unit further includes: The second cross-flow fan is defined within the air conditioner housing, which defines a first fan duct and a second fan duct. Both the first fan duct and the second fan duct are connected to the air inlet. The first cross-flow fan is rotatably disposed in the first fan duct, and the second cross-flow fan is rotatably disposed in the second fan duct. The second cross-flow fan and the first cross-flow fan are arranged side by side along the width direction of the air conditioner housing. The air outlet includes a first upper air outlet, a first side air outlet, a first lower air outlet, a second upper air outlet, a second side air outlet, and a second lower air outlet. The first upper air outlet, the first side air outlet, and the first lower air outlet are all connected to the first fan duct, and the second upper air outlet, the second side air outlet, and the second lower air outlet are all connected to the second fan duct. When the first cross-flow fan rotates, it can draw indoor air into the first fan duct through the air inlet. The first cross-flow fan is also used to blow the heat-treated air out through the first upper air outlet, the first side air outlet, and the first lower air outlet when it rotates. When the second cross-flow fan rotates, it can draw indoor air into the second fan duct through the air inlet. The second cross-flow fan is also used to blow the heat-treated air out through the second upper air outlet, the second side air outlet, and the second lower air outlet when it rotates.

[0018] Compared with the prior art, the beneficial effects of this application are as follows: In this application, since the rotor is spaced around the stator around the axis, and since the coil can drive the rotor to align with the center of the axis when energized, there is no contact point between the rotor and the stator. In layman's terms, the rotor is suspended relative to the stator. This reduces the friction between the rotor and the stator, thereby making it easier to increase the speed of the first cross-flow fan while reducing the operating noise of the first cross-flow fan.

[0019] In addition, when the first limiting member is disposed on the first rotating shaft and abuts against the lower end of the first bearing, and the second limiting member is disposed on the first rotating shaft and abuts against the upper end of the first bearing, the first limiting member, the first bearing and the second limiting member work together to make the first rotating shaft only rotate around the axis and unable to move up and down along the above-mentioned height direction.

[0020] When the first shaft cannot move up and down along the aforementioned height direction, since the first shaft is connected to the first cross-flow fan, the first cross-flow fan will not be able to move up and down. The bearing module can bear the weight of the first cross-flow fan through the first shaft, thereby preventing the first cross-flow fan from falling abnormally downward. This can prevent the rotor from moving downward relative to the stator due to the first cross-flow fan falling abnormally downward, thus preventing the first drive module from failing.

[0021] Furthermore, since both the bearing module and the first drive module are located at the top of the first cross-flow fan, and the bearing module can bear the weight of the first cross-flow fan, that is, the first drive module that drives the first cross-flow fan to rotate and the bearing module that bears the weight of the first cross-flow fan are both integrated at the top of the first cross-flow fan. In this way, compared with setting the structure that drives the first cross-flow fan to rotate and the structure that bears the weight of the first cross-flow fan at the two ends of the first cross-flow fan respectively, when the first cross-flow fan expands and undergoes a slight deformation, the first cross-flow fan can release the expansion size downward, thereby ensuring that the rotation of the first cross-flow fan is more stable.

[0030] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0031] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0032] A floor-standing air conditioner indoor unit is a device that can regulate indoor temperature and improve user comfort. Floor-standing air conditioner indoor units in related technologies typically include a cross-flow fan. During rotation, the cross-flow fan blows heated air from inside the indoor unit into the room, thereby achieving the purpose of heating or cooling and regulating indoor temperature. However, the cross-flow fans in related technologies experience significant friction during rotation, making it difficult to increase their speed and resulting in considerable noise. Therefore, this application provides a novel floor-standing air conditioner indoor unit to solve the aforementioned problems.

[0033] Figure 1This is a structural schematic diagram of a vertical air conditioner indoor unit 100 provided in one embodiment of this application. Figure 2 yes Figure 1 A structural schematic diagram of the vertical air conditioner indoor unit 100 from another perspective.

[0034] See Figure 1 and Figure 2 The vertical air conditioner indoor unit 100 includes an air conditioner housing 1, on which an air inlet 11 and an air outlet 12 are provided.

[0035] The shape of the air conditioner housing 1 can be a cuboid or a cylinder, etc., and this embodiment does not limit this. The material of the air conditioner housing 1 can be plastic or metal, etc., and this embodiment does not limit this either.

[0036] The air inlet 11 can be located on the back of the air conditioner housing 1, and the air outlet 12 can be located on the front of the air conditioner housing 1. Of course, the air inlet 11 and the air outlet 12 can also be located on other surfaces of the air conditioner housing 1, such as the left and right surfaces of the air conditioner housing 1. This embodiment does not limit this.

[0037] It should be noted that, taking the air conditioner casing 1 as a cuboid as an example, for the vertical air conditioner indoor unit 100, the bottom surface of the air conditioner casing 1 refers to the side facing the ground, and the front surface of the air conditioner casing 1 refers to the side facing the user, which usually has buttons and other features for user operation. The back surface of the air conditioner casing 1 refers to the side opposite to the front surface of the air conditioner casing 1.

[0038] In some embodiments, see Figure 3 and Figure 4 , Figure 3 yes Figure 2 The structural diagram of the vertical air conditioner indoor unit 100, with some parts omitted. Figure 4 yes Figure 3 An exploded view of a vertical air conditioner indoor unit 100, the vertical air conditioner indoor unit 100 including a first cross-flow fan 2a, the first cross-flow fan 2a being rotatably disposed inside the air conditioner housing 1 and along the height direction of the air conditioner housing 1 ( Figure 4 (Extends along the Z-axis).

[0039] Since the first cross-flow fan 2a is rotatably disposed inside the air conditioner housing 1 and extends along the height direction of the air conditioner housing 1, the first cross-flow fan 2a can be extended approximately in the vertical direction.

[0040] For the vertical air conditioner indoor unit 100, the space inside the air conditioner casing 1 along the aforementioned height direction is usually large. Therefore, by extending the first cross-flow fan 2a along the height direction of the air conditioner casing 1, the first cross-flow fan 2a can make full use of the space inside the air conditioner casing 1. Thus, when selecting a model, a longer first cross-flow fan 2a can be chosen, which can improve the air volume of the vertical air conditioner indoor unit 100 to a certain extent.

[0041] In some embodiments, see Figure 5 , Figure 6 and Figure 7 , Figure 5 This is a structural schematic diagram of the vertical air conditioner indoor unit 100 in section 3 from another perspective. Figure 6 yes Figure 5 A cross-sectional view of the vertical air conditioner indoor unit 100 at position AA. Figure 7 yes Figure 6 The schematic diagram of the structure of the heat exchanger 3 shows that the vertical air conditioner indoor unit 100 includes a heat exchanger 3, which is installed inside the air conditioner casing 1. When the first cross-flow fan 2a rotates, it can draw indoor air into the air conditioner casing 1 through the air inlet 11. The heat exchanger 3 is used to heat treat the air. The first cross-flow fan 2a is also used to blow the heat-treated air out through the air outlet 12 when it rotates.

[0042] Since the first cross-flow fan 2a is located inside the air conditioner casing 1, when the first cross-flow fan 2a starts to rotate, it can draw indoor air into the air conditioner casing 1 through the air inlet 11. After the indoor air is drawn into the air conditioner casing 1 through the air inlet 11, since the heat exchanger 3 is located inside the air conditioner casing 1, the heat exchanger 3 can heat-treat the air entering the air conditioner casing 1. Then, when the first cross-flow fan 2a continues to rotate, it can blow the heat-treated air out through the air outlet 12, thereby achieving the purpose of heating or cooling the room.

[0043] The heat exchanger 3 can be an evaporator. The cross-section of the heat exchanger 3 can be U-shaped and set corresponding to the air inlet 11. In this way, the air entering the air conditioner casing 1 through the air inlet 11 can come into contact with the heat exchanger 3 in large quantities, thereby improving the heat exchange efficiency of the heat exchanger 3.

[0044] In some embodiments, see Figure 3 , Figure 4 and Figure 8 , Figure 8 yes Figure 3 The diagram below shows the structure of the vertical air conditioner indoor unit 100 after omitting some of its components. The vertical air conditioner indoor unit 100 includes a first drive module 4, which is connected to the upper end of the first cross-flow fan 2a and is used to drive the first cross-flow fan 2a to rotate.

[0045] The first drive module 4 can be connected to the upper end of the first cross-flow fan 2a by screws or by welding or other means. This embodiment does not limit this.

[0046] In some embodiments, see Figure 8 The vertical air conditioner indoor unit 100 includes a first drive cover 5, which covers the first drive module 4 and is connected to the air conditioner housing 1.

[0047] Since the first drive cover 5 is mounted on the first drive module 4 and connected to the air conditioner housing 1, when the first drive module 4 malfunctions and needs maintenance, it is very convenient to remove the first drive cover 5 from the air conditioner housing 1 to maintain the first drive module 4, making the maintenance of the first drive module 4 very convenient.

[0048] In addition, since the first drive module 4 is connected to the upper end of the first cross-flow fan 2a, the first drive module 4 can be located at the top of the air conditioner housing 1. This makes it easier for a person to reach into the air conditioner housing 1 to disassemble the first drive module 4 and also makes it easier to take the first drive module 4 out of the air conditioner housing 1. Compared with setting the first drive module 4 at the bottom end of the first cross-flow fan 2a, this can further improve the convenience of maintenance of the first drive module 4.

[0049] The shape of the first drive cover 5 can be disc-shaped or other possible shapes, and this embodiment does not limit it.

[0050] The aforementioned first drive cover 5 can be detachably mounted on the air conditioner housing 1 by means of screws or other means, which makes it very convenient to remove the first drive cover 5 from the air conditioner housing 1.

[0051] In some embodiments, see Figure 9 , Figure 10 and Figure 11 , Figure 9 yes Figure 8 A structural schematic diagram of the vertical air conditioner indoor unit 100 from another perspective. Figure 10 yes Figure 9 A structural schematic diagram of the vertical air conditioner indoor unit 100 from another perspective. Figure 11 yes Figure 10 The enlarged view of the vertical air conditioner indoor unit 100 at position B shows that the first drive module 4 includes a stator 41 connected to the first drive cover 5. (See also...) Figure 12 , Figure 12 yes Figure 11A cross-sectional view of the stator 41 shows that the stator 41 has a first central hole 411 that extends through the stator 41 along the height direction, and a coil is also provided on the stator 41.

[0052] The stator 41 can be connected to the first drive cover 5 in various ways, such as by screws, and this embodiment does not limit this.

[0053] In some embodiments, see Figure 11 The first drive module 4 includes a rotor 42, which is spaced around the axis O of the first central hole 411 and sleeved around the periphery of the stator 41. The rotor 42 is connected to the upper end of the first cross-flow fan 2a. When the coil is energized, it can drive the rotor 42 to rotate around the axis O.

[0054] Since the rotor 42 is spaced around the axis O and fitted around the stator 41, the coils on the stator 41 will be located in the magnetic field of the rotor 42. When the coils on the stator 41 are located in the magnetic field of the rotor 42, when the coils are energized, a magnetic force will be generated between the coils and the rotor 42. This magnetic force can drive the rotor 42 to align with the center of the axis O and rotate around the axis O.

[0055] When the rotor 42 rotates around the axis O, since the rotor 42 is connected to the top of the first cross-flow fan 2a, it can drive the first cross-flow fan 2a to rotate. When the first cross-flow fan 2a rotates, it can achieve the purpose of drawing indoor air into the air conditioner casing 1 through the air inlet 11 and blowing the heat-treated air out through the air outlet 12.

[0056] Since the rotor 42 is spaced around the axis O and sleeved around the stator 41, and since the coil can drive the rotor 42 to align with the center of the axis O when energized, there is no contact point between the rotor 42 and the stator 41. In simple terms, the rotor 42 is suspended relative to the stator 41. This reduces the friction between the rotor 42 and the stator 41, thereby making it easier to increase the speed of the first cross-flow fan 2a while reducing the operating noise of the first cross-flow fan 2a.

[0057] It should be noted that there are various ways to connect the rotor 42 to the top of the first cross-flow fan 2a. For example, it can be connected by screws or by ultrasonic welding. This embodiment does not limit this method.

[0058] In some embodiments, see Figure 11 and Figure 12 The first drive module 4 includes a first rotating shaft 43, which is connected to the first cross-flow fan 2a and located in the first central hole 411.

[0059] Since the first rotating shaft 43 is connected to the first cross-flow fan 2a and located within the first central hole 411, the wall of the first central hole 411 can limit the rotation of the first rotating shaft 43 radially, thereby preventing the first rotating shaft 43 from wobbling significantly radially. On the one hand, this prevents the first cross-flow fan 2a from wobbling significantly radially, making its rotation smoother. On the other hand, it also ensures that the rotor 42 is aligned with the axis O as much as possible, thus ensuring the stability of the gap between the rotor 42 and the stator 41 radially along the first rotating shaft 43, and further ensuring the stability of the first drive module 4's operation.

[0060] In some embodiments, see Figure 11 The vertical air conditioner indoor unit 100 includes a bearing module 6, the bearing module 6 being along the height direction ( Figure 11 The bearing module 6 (in the Z-axis direction) is located between the stator 41 and the first drive cover 5. The bearing module 6 includes a first bearing 6a, which is rotatably sleeved on the first rotating shaft 43.

[0061] Since the bearing module 6 is located between the stator 41 and the first drive cover 5 along the height direction, the bearing module 6 will be fixed along the height direction, thereby preventing the bearing module 6 from moving up and down along the height direction.

[0062] In addition, since the first bearing 6a is rotatably sleeved on the first rotating shaft 43, and the bearing module 6 is limited in the height direction between the stator 41 and the first drive cover 5, the first bearing 6a can guide the rotation of the first rotating shaft 43, making the first rotating shaft 43 more stable when rotating.

[0063] In some embodiments, see Figure 11 and Figure 13 , Figure 13 yes Figure 11 A partial enlarged view at position C shows that the vertical air conditioner indoor unit 100 includes a first limiting member 7, which is disposed on the first rotating shaft 43 and abuts against the lower end of the first bearing 6a.

[0064] Since the first limiting member 7 is disposed on the first rotating shaft 43 and abuts against the lower end of the first bearing 6a, when the first rotating shaft 43 moves upward relative to the bearing module 6 in the height direction, the first bearing 6a will prevent the first limiting member 7 from moving upward in the height direction, thereby achieving the purpose of preventing the first rotating shaft 43 from moving upward in the height direction.

[0065] In some embodiments, see Figure 13The vertical air conditioner indoor unit 100 includes a second limiting member 8, which is disposed on the first rotating shaft 43 and abuts against the upper end of the first bearing 6a.

[0066] Since the second limiting member 8 is disposed on the first rotating shaft 43 and abuts against the upper end of the first bearing 6a, when the first rotating shaft 43 moves downward relative to the bearing module 6 in the height direction, the first bearing 6a will prevent the second limiting member 8 from moving downward in the height direction, thereby achieving the purpose of preventing the first rotating shaft 43 from moving downward in the height direction.

[0067] As can be seen, when the first limiting member 7 is disposed on the first rotating shaft 43 and abuts against the lower end of the first bearing 6a, and the second limiting member 8 is disposed on the first rotating shaft 43 and abuts against the upper end of the first bearing 6a, under the combined action of the first limiting member 7, the first bearing 6a and the second limiting member 8, the first rotating shaft 43 can only rotate around the axis O, and cannot move up and down along the aforementioned height direction.

[0068] When the first rotating shaft 43 cannot move up and down along the aforementioned height direction, since the first rotating shaft 43 is connected to the first cross-flow fan 2a, the first cross-flow fan 2a will not be able to move up and down. The bearing module 6 can bear the weight of the first cross-flow fan 2a through the first rotating shaft 43, thereby preventing the first cross-flow fan 2a from falling abnormally downward. This can prevent the rotor 42 from moving downward relative to the stator 41 due to the first cross-flow fan 2a falling abnormally downward, thus preventing the first drive module 4 from failing.

[0069] Furthermore, since both the bearing module 6 and the first drive module 4 are located at the top of the first cross-flow fan 2a, and the bearing module 6 can bear the weight of the first cross-flow fan 2a, that is, the first drive module 4 that drives the first cross-flow fan 2a to rotate and the bearing module 6 that bears the weight of the first cross-flow fan 2a are both integrated at the top of the first cross-flow fan 2a. In this way, compared with setting the structure that drives the first cross-flow fan 2a to rotate and the structure that bears the weight of the first cross-flow fan 2a to rotate at opposite ends of the first cross-flow fan 2a, when the first cross-flow fan 2a expands and undergoes a slight deformation, the first cross-flow fan 2a can release the expansion size downwards, thereby ensuring that the rotation of the first cross-flow fan 2a is more stable.

[0070] Considering that the first limiting member 7 is located below the second limiting member 8 along the aforementioned height direction, and the first limiting member 7 is used to support the weight of the first cross-flow fan 2a, in order to avoid the first limiting member 7 being deformed due to excessive force, in some embodiments, the thickness of the first limiting member 7 is greater than the thickness of the second limiting member 8.

[0071] By making the thickness of the first limiting member 7 greater than that of the second limiting member 8, the mechanical strength of the first limiting member 7 can be stronger than that of the second limiting member 8. This allows the first limiting member 7 to better support the first cross-flow fan 2a, thereby preventing the first limiting member 7 from deforming due to excessive force.

[0072] In some embodiments, see Figure 13 The first bearing 6a includes an inner ring 61, which is sleeved on the first rotating shaft 43. A first limiting member 7 abuts against the lower end of the inner ring 61, and a second limiting member 8 abuts against the upper end of the inner ring 61.

[0073] Since the first limiting member 7 abuts against the lower end of the inner ring member 61 and the second limiting member 8 abuts against the upper end of the inner ring member 61, the limiting effect of the first limiting member 7 and the second limiting member 8 can prevent the first rotating shaft 43 from moving up and down relative to the inner ring member 61 in the above-mentioned height direction.

[0074] In some embodiments, see Figure 11 and Figure 13 The first bearing 6a includes an outer ring 62, which is rotatably fitted around the inner ring 61 and is positioned between the stator 41 and the first drive cover 5 along the height direction.

[0075] Since the outer ring 62 is rotatably fitted around the outer ring 61, the inner ring 61 can rotate relative to the outer ring 62 about the axis O, which in turn ensures that the first rotating shaft 43 can rotate relative to the outer ring 62 about the axis O.

[0076] To achieve the purpose of rotatably fitting the outer ring 62 around the inner ring 61, in some embodiments, see [reference needed]. Figure 13 A ball bearing 65 can be provided between the outer ring 62 and the inner ring 61. In this way, the outer ring 62 can rotate more smoothly relative to the inner ring 61 under the action of the ball bearing 65.

[0077] In some embodiments, see Figure 11 and Figure 12 The upper surface of the stator 41 is provided with a countersunk hole 412 coaxial with the axis O, and the outer ring member 62 is located inside the countersunk hole 412. Along the height direction, the outer ring member 62 is limited to the area between the first drive cover 5 and the bottom of the countersunk hole 412.

[0078] Since the outer ring component 62 is located within the countersunk hole 412, on the one hand, the countersunk hole 412 provides precise radial positioning for the outer ring component 62, resulting in higher positional accuracy when the outer ring component 62 is placed on the upper surface of the stator 41. On the other hand, by positioning the outer ring component 62 within the countersunk hole 412, the outer ring component 62 can fully utilize the space along the height direction of the countersunk hole 412, thereby ensuring that the overall structure formed by the first drive module 4 and the bearing module 6 is aligned along the aforementioned height direction to a certain extent. Figure 11 The thickness is even thinner in the Z-axis direction.

[0079] In addition, since the outer ring 62 is located between the bottom of the first drive cover 5 and the countersunk hole 412, the axial constraint of the outer ring 62 can be achieved by the cooperation between the first drive cover 5 and the countersunk hole 412. No additional bolts, clips or other fasteners are required. The positioning of the outer ring 62 along the above-mentioned height direction can be achieved by the bidirectional constraint between the bottom of the countersunk hole 412 and the first drive cover 5. The structure is simple and compact.

[0080] In some embodiments, see Figure 13 One of the first limiting member 7 and the second limiting member 8 is detachably disposed on the first rotating shaft 43.

[0081] By making one of the first limiting member 7 and the second limiting member 8 detachably disposed on the first rotating shaft 43, when it is necessary to install the first bearing 6a on the first rotating shaft 43 or remove it from the first rotating shaft 43, it can be achieved simply by removing one of the first limiting member 7 and the second limiting member 8 from the first rotating shaft 43, making the installation and removal of the first bearing 6a more convenient.

[0082] In some embodiments, see Figure 13 The first limiting member 7 is fixedly set, and the second limiting member 8 is detachably set. The first limiting member 7 is a limiting shoulder, and the second limiting member 8 is a limiting snap ring.

[0083] Since the second limiting member 8 is located on the first rotating shaft 43 and abuts against the upper end of the first bearing 6a, and the first limiting member 7 abuts against the lower end of the first bearing 6a, and the first bearing 6a is usually easy to install into the first rotating shaft 43 from top to bottom, by making the first limiting member 7 a limiting shoulder and the second limiting member 8 a limiting snap ring, when the lower end of the first bearing 6a abuts against the first limiting member 7 during the process of installing the first bearing 6a into the first rotating shaft 43 from top to bottom, it can be considered that the first bearing 6a is installed in place. At this time, the second limiting member 8 is then installed on the first rotating shaft 43, thereby achieving the purpose of fixing the first bearing 6a to the first rotating shaft 43.

[0084] It can be seen that when the first limiting member 7 is fixedly set and the second limiting member 8 is detachably set, it conforms to the installation logic when the first bearing 6a is installed on the first rotating shaft 43. Therefore, it makes it convenient to install the first bearing 6a on the first rotating shaft 43.

[0085] Of course, in other embodiments, the first limiting member 7 and the second limiting member 8 can be detachably provided, and this embodiment does not limit this.

[0086] In some embodiments, see Figure 13 The bearing module 6 also includes a first bearing bracket 63, which is sleeved on the periphery of the outer ring 62 and is positioned between the stator 41 and the first drive cover 5 along the height direction.

[0087] By fitting the first bearing bracket 63 around the outer ring 62, it serves two purposes: firstly, it provides a mounting base for the outer ring 62, limiting its radial and axial movement and thus ensuring better operational stability of the bearing module 6; secondly, it effectively transfers the radial and axial loads borne by the outer ring 62 during operation to the stator 41 and the first drive cover 5, preventing the loads from directly acting on the balls of the first bearing 6a, thereby extending the lifespan of the first bearing 6a. Furthermore, the first bearing bracket 63 also provides protection, preventing external dust and impurities from entering between the outer ring 62 and the inner ring 61, thus providing a clean working environment for the balls of the first bearing 6a and ensuring its smooth and stable operation.

[0088] In some embodiments, see Figure 13 and Figure 14 , Figure 14 yes Figure 13 A schematic diagram of the structure of the first bearing bracket 63 is shown. The first bearing bracket 63 includes a first surrounding part 631, which surrounds the peripheral wall of the outer ring member 62.

[0089] Since the first surrounding portion 631 surrounds the peripheral wall of the outer ring member 62, the first surrounding portion 631 can protect the outer ring member 62, preventing the outer ring member 62 from directly contacting external parts, thereby improving the service life of the outer ring member 62.

[0090] In some embodiments, see Figure 13 and Figure 14 The first bearing bracket 63 includes a first bottom part 632, which is disposed at the lower end of the first surrounding part 631, and the upper surface of the first bottom part 632 abuts against the lower end of the outer ring part 62.

[0091] By placing the first bottom part 632 at the lower end of the first surrounding part 631, and having the upper surface of the first bottom part 632 abut against the lower end of the outer ring part 62, the first bottom part 632 and the first surrounding part 631 can together define the position of the outer ring part 62, making the outer ring part 62 more stably mounted on the first bearing bracket 63.

[0092] Specifically, see Figure 14 Both the first surrounding portion 631 and the first bottom attachment portion 632 can be ring-shaped structures.

[0093] In some embodiments, see Figure 13 The bearing module 6 also includes a first buffer member 64, which is sleeved around the periphery of the first surrounding part 631 and is positioned between the stator 41 and the first drive cover 5 along the height direction.

[0094] Since the first buffer 64 is sleeved around the first surrounding part 631 and the first buffer 64 is limited to the space between the stator 41 and the first drive cover 5 along the height direction, the first buffer 64 can absorb noise and reduce vibration. This can prevent the noise and vibration generated when the first cross-flow fan 2a rotates from being transmitted to the stator 41 and the first drive cover 5 through the first rotating shaft 43 and the bearing module 6, thereby making the operation of the vertical air conditioner indoor unit 100 quieter and more stable.

[0095] The first buffer 64 mentioned above can be a rubber buffer or a silicone buffer, etc., and this embodiment does not limit it.

[0096] In some embodiments, see Figure 13 and Figure 15 , Figure 15 yes Figure 11 A cross-sectional view of the first buffer member 64, the first buffer member 64 includes a second surrounding portion 641, the second surrounding portion 641 surrounding the peripheral wall of the first surrounding portion 631.

[0097] The second surrounding portion 641 can be a ring-shaped structure.

[0098] By having the second surrounding portion 641 surround the peripheral wall of the first surrounding portion 631, the second surrounding portion 641 can wrap around the first surrounding portion 631, thereby preventing the first surrounding portion 631 from directly contacting the stator 41 or the first drive cover 5.

[0099] In some embodiments, see Figure 13 and Figure 15The first buffer member 64 includes a top adhesive portion 642 and a second bottom adhesive portion 643. The top adhesive portion 642 is connected to the upper end of the second surrounding portion 641 and abuts against the upper end of the first surrounding portion 631 and the upper end of the outer ring member 62. The second bottom adhesive portion 643 is connected to the bottom end of the second surrounding portion 641 and abuts against the lower end of the first bottom adhesive portion 632. Along the height direction, the top adhesive portion 642 abuts against the first drive cover 5, and the second bottom adhesive portion 643 abuts against the stator 41.

[0100] By connecting the top patch 642 to the upper end of the second surrounding part 641 and abutting against the upper end of the first surrounding part 631 and the upper end of the outer ring 62, and connecting the second bottom patch 643 to the bottom end of the second surrounding part 641 and abutting against the lower end of the first bottom patch 632, the first buffer 64 can wrap around the first bearing bracket 63 from three directions. On the one hand, this better prevents noise and vibration from being transmitted to the stator 41 and the first drive cover 5 through the first rotating shaft 43 and the bearing module 6. On the other hand, the first buffer 64 can also act as a dust cover, preventing dust from entering the first bearing bracket 63, thereby extending the service life of the bearing module 6 and improving the smoothness of the bearing module 6's operation.

[0101] It should be noted that both the top adhesive portion 642 and the second bottom adhesive portion 643 can be annular structures.

[0102] In some embodiments, see Figure 10 and Figure 16 , Figure 16 yes Figure 10 The enlarged view at position D shows that the vertical air conditioner indoor unit 100 also includes a rotating module 9, and the bottom end of the first cross-flow fan 2a is rotatably mounted on the air conditioner casing 1 via the rotating module 9.

[0103] When the bottom end of the first cross-flow fan 2a is rotatably mounted on the air conditioner housing 1 via the rotating module 9, on the one hand, the rotating module 9 can fix the bottom end of the first cross-flow fan 2a, thereby preventing the bottom end of the first cross-flow fan 2a from swaying left and right; on the other hand, the rotating module 9 can guide the rotation of the first cross-flow fan 2a, making the first cross-flow fan 2a more stable and smooth when rotating.

[0104] Specifically, the rotating module 9 may include a second bearing, and a second rotating shaft may be provided at the bottom end of the first cross-flow fan 2a. The second rotating shaft is rotatably inserted into the second bearing, so that the bottom end of the first cross-flow fan 2a can be rotatably set to the air conditioner housing 1 through the second bearing.

[0105] In some embodiments, see Figure 4The vertical air conditioner indoor unit 100 also includes a second cross-flow fan 2b. The air conditioner housing 1 defines a first fan duct 13a and a second fan duct 13b. Both the first fan duct 13a and the second fan duct 13b are connected to the air inlet 11. The first cross-flow fan 2a is rotatably disposed in the first fan duct 13a, and the second cross-flow fan 2b is rotatably disposed in the second fan duct 13b. The second cross-flow fan 2b and the first cross-flow fan 2a are arranged side by side along the width direction of the air conditioner housing 1.

[0106] By arranging the second cross-flow fan 2b and the first cross-flow fan 2a side by side along the width direction of the air conditioner casing 1, the space in the width direction of the air conditioner casing 1 can be fully utilized. Compared with the arrangement of the second cross-flow fan 2b and the first cross-flow fan 2a along the height direction of the air conditioner casing 1, the height of the vertical air conditioner indoor unit 100 can be reduced to a certain extent.

[0107] In addition, when the vertical air conditioner indoor unit 100 also includes a second cross-flow fan 2b, the air volume of the vertical air conditioner indoor unit 100 can be increased, thereby improving the heating and cooling effect of the vertical air conditioner indoor unit 100.

[0108] In some embodiments, see Figure 2 The air outlet 12 includes a first upper air outlet 121, a first side air outlet 122, a first lower air outlet 123, a second upper air outlet 124, a second side air outlet 125, and a second lower air outlet 126. The first upper air outlet 121, the first side air outlet 122, and the first lower air outlet 123 are all connected to the first fan duct 13a, and the second upper air outlet 124, the second side air outlet 125, and the second lower air outlet 126 are all connected to the second fan duct 13b.

[0109] Both the first upper air outlet 121 and the second upper air outlet 124 can be located on the front of the air conditioner housing 1.

[0110] Of course, the first upper air outlet 121 and the second upper air outlet 124 can also be provided on other surfaces of the air conditioner housing 1, and this embodiment does not limit this.

[0111] In some embodiments, see Figure 2 The first upper air outlet 121 and the second upper air outlet 124 can be connected to each other to form a total upper air outlet, which makes the appearance of the air conditioner housing 1 more concise.

[0112] Of course, in other embodiments, the first upper air outlet 121 and the second upper air outlet 124 may also be independent air outlets, and this embodiment does not limit this.

[0113] In some embodiments, see Figure 2The first side air outlet 122 and the second side air outlet 125 can be respectively located on the left and right sides of the air conditioner housing 1. When the first side air outlet 122 and the second side air outlet 125 are respectively located on the left and right sides of the air conditioner housing 1, the vertical air conditioner indoor unit 100 can form a wraparound airflow, which is gentler and provides a better user experience.

[0114] In some embodiments, see Figure 2 The first lower air outlet 123 and the second lower air outlet 126 can both be located on the front of the air conditioner casing 1. The height of the first lower air outlet 123 and the second lower air outlet 126 is lower than the height of the first upper air outlet 121 and the second upper air outlet 124. In this way, the air outlet through the first lower air outlet 123 and the second lower air outlet 126 can form a carpet-like airflow, which is more suitable for hot air to be blown out of the room from the first lower air outlet 123 and the second lower air outlet 126, so as to better heat the lower parts of the room.

[0115] Among them, see Figure 2 The first lower air outlet 123 and the second lower air outlet 126 mentioned above can be connected to each other to form a total lower air outlet, which makes the appearance of the air conditioner housing 1 more concise.

[0116] Of course, in other embodiments, the first lower air outlet 123 and the second lower air outlet 126 may also be two independent air outlets, and this embodiment does not limit this.

[0117] In some embodiments, see Figure 2 and Figure 4 When the first cross-flow fan 2a rotates, it can draw indoor air into the first fan duct 13a through the air inlet 11. The first cross-flow fan 2a is also used to blow out the heat-treated air through the first upper air outlet 121, the first side air outlet 122 and the first lower air outlet 123 respectively when it rotates. When the second cross-flow fan 2b rotates, it can draw indoor air into the second fan duct 13b through the air inlet 11. The second cross-flow fan 2b is also used to blow out the heat-treated air through the second upper air outlet 124, the second side air outlet 125 and the second lower air outlet 126 respectively when it rotates.

[0118] In this way, the air outlets 121 and 124 can form a skylight wind, the air outlets 122 and 125 can form an enveloping wind, and the air outlets 123 and 126 can form a carpet wind, making the air outlets more diverse and thus improving the user experience of the vertical air conditioner indoor unit 100.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
