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 resulting in considerable operating noise. Utility Model Content

[0003] This application discloses a vertical air conditioner indoor unit, whose cross-flow fan accelerates quickly, operates with low noise, and can better ensure the normal rotation of the cross-flow fan.

[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 cover is disposed on the air conditioner housing; A first drive module, connected along the height direction between the top of the first cross-flow fan and the first cover, is used to drive the first cross-flow fan to rotate, and includes: A stator, which is connected to the first cover, and a coil is provided on the stator; A rotor assembly is spaced around the stator around its axis and connected to the top of the first cross-flow fan. The rotor assembly is provided with a first magnetic element. When the coil is energized, it can drive the rotor assembly to align with the center of the axis and rotate around the axis. The vertical air conditioner indoor unit also includes a first load-bearing module, which comprises: A second magnetic element is disposed on the rotor assembly; A third magnetic element is disposed on the stator and spaced apart from the second magnetic element along the height direction. The third magnetic element is used to provide an upward magnetic force to the second magnetic element along the height direction.

[0005] Because the rotor assembly is spaced around the stator's axis and is positioned around the stator's periphery, and because the coil can drive the rotor assembly to align with the axis center when energized, there are no contact points between the rotor assembly and the stator. In simple terms, the rotor assembly is suspended in the radial direction of the stator relative to it. This reduces the friction between the rotor assembly and the stator, thereby making it easier to increase the speed of the first cross-flow fan while reducing its operating noise.

[0006] Furthermore, since the second magnetic element is disposed on the rotor assembly and the third magnetic element is disposed on the stator and spaced apart from the second magnetic element along the height direction, the third magnetic element can provide an upward magnetic force to the second magnetic element along the height direction. This force can support the first cross-flow fan upward along the aforementioned height direction, allowing the second magnetic element to suspend above the third magnetic element. This force can overcome the gravity acting on the first cross-flow fan. In this way, on the one hand, it can prevent the first cross-flow fan from falling downward and breaking; on the other hand, it can also prevent the first drive module from failing due to the rotor assembly moving downward relative to the stator when the first cross-flow fan falls downward. This can better ensure the normal rotation of the first cross-flow fan.

[0007] Furthermore, since the second magnetic component is disposed on the rotor assembly and the third magnetic component is disposed on the stator and spaced apart from the second magnetic component along the height direction, that is, the first load-bearing module is integrated into the first drive module. Therefore, both the first load-bearing module and the first drive module can be located at the top of the first cross-flow fan. In this way, there is no need to set the first load-bearing module at the bottom of the first cross-flow fan to bear the weight of the first cross-flow fan, so that the bottom of the first cross-flow fan can be a free end that can move freely along the height direction.

[0008] In this way, when the first cross-flow fan expands due to heat and changes in size, the bottom of the first cross-flow fan can be released downwards. This avoids the situation where the first cross-flow fan can only expand upwards due to the change in size, which would force the spacing between the second and third magnetic components along the height direction to change. This can better ensure the normal rotation of the first cross-flow fan.

[0009] Optionally, the rotor assembly includes: The rotor is spaced around the axis and sleeved around the stator, and the rotor is connected to the top of the first cross-flow fan. The first magnetic element is disposed on the rotor. The stator is provided with a first central hole that penetrates the stator along the height direction and is coaxial with the axis. A first rotating shaft is connected to the rotor and is coaxial with the axis, and the first rotating shaft passes through a first central hole.

[0010] Optionally, the second magnetic element is located above the third magnetic element along the height direction, and the two ends of the second and third magnetic elements opposite to each other have the same polarity.

[0011] Optionally, the third magnetic element is disposed at the top of the stator, and the second magnetic element is disposed at the first rotating shaft.

[0012] Optionally, the rotor assembly further includes: The first limiting member is disposed on the first rotating shaft; The second limiting member is disposed on the first rotating shaft and is spaced apart from the first limiting member along the height direction. The second magnetic member is sleeved on the first rotating shaft and is limited between the first limiting member and the second limiting member.

[0013] Optionally, the first limiting member is located above the second limiting member along the height direction, and the first limiting member is detachably provided.

[0014] Optionally, the first load-bearing module further includes: Mounting base, the mounting base comprising: An end cap portion is sleeved on the first rotating shaft, located above the third magnetic element and spaced apart from the third magnetic element, and the second magnetic element is disposed on the side of the end cap portion facing the third magnetic element; A surrounding portion is disposed around the periphery of the end cap portion and spaced around the peripheral wall of the third magnetic element.

[0015] Optionally, the first driving module further includes: A first bearing, which is sleeved on the first rotating shaft; The first buffer element is located in the gap between the wall of the first central hole and the first bearing.

[0016] Optionally, the first buffer is a flexible ring, which is sleeved on the first bearing.

[0017] Optionally, the vertical air conditioner indoor unit further includes a volute, which is located inside the air conditioner housing. A first cross-flow fan is rotatably disposed inside the volute, with the bottom end of the first cross-flow fan spaced apart from the volute along the height direction.

[0018] 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. The second cover is disposed on the air conditioner housing; The second drive module is connected along the height direction between the top of the second cross-flow fan and the second cover, and is used to drive the second cross-flow fan to rotate. 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.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: In this application, since the rotor assembly is spaced around the stator's axis and is positioned around the stator's periphery, and since the coil can drive the rotor assembly to align with the axis center when energized, there are no contact points between the rotor assembly and the stator. In simple terms, the rotor assembly is suspended in the radial direction of the stator relative to the stator. This reduces the friction between the rotor assembly 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.

[0020] Furthermore, since the second magnetic element is disposed on the rotor assembly and the third magnetic element is disposed on the stator and spaced apart from the second magnetic element along the height direction, the third magnetic element can provide an upward magnetic force to the second magnetic element along the height direction. This force can support the first cross-flow fan upward along the aforementioned height direction, allowing the second magnetic element to suspend above the third magnetic element. This force can overcome the gravity acting on the first cross-flow fan. In this way, on the one hand, it can prevent the first cross-flow fan from falling downward and breaking; on the other hand, it can also prevent the first drive module from failing due to the rotor assembly moving downward relative to the stator when the first cross-flow fan falls downward. This can better ensure the normal rotation of the first cross-flow fan.

[0021] Furthermore, since the second magnetic component is disposed on the rotor assembly and the third magnetic component is disposed on the stator and spaced apart from the second magnetic component along the height direction, that is, the first load-bearing module is integrated into the first drive module. Therefore, both the first load-bearing module and the first drive module can be located at the top of the first cross-flow fan. In this way, there is no need to set the first load-bearing module at the bottom of the first cross-flow fan to bear the weight of the first cross-flow fan, so that the bottom of the first cross-flow fan can be a free end that can move freely along the height direction.

[0022] In this way, when the first cross-flow fan expands due to heat and changes in size, the bottom of the first cross-flow fan can be released downwards. This avoids the situation where the first cross-flow fan can only expand upwards due to the change in size, which would force the spacing between the second and third magnetic components along the height direction to change. This can better ensure the normal rotation of the first cross-flow fan. Attached Figure Description

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

[0034] Figure 1 This 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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 3An exploded view of a vertical air conditioner indoor unit 100, the vertical air conditioner indoor unit 100 including a first cross-flow fan 2, the first cross-flow fan 2 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).

[0040] Since the first cross-flow fan 2 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 2 can be extended approximately in the vertical direction.

[0041] For the vertical air conditioner indoor unit 100, the space inside the air conditioner casing 1 along the height direction is usually large. Therefore, by extending the first cross-flow fan 2 along the height direction of the air conditioner casing 1, the first cross-flow fan 2 can make full use of the space in the height direction of the air conditioner casing 1. Thus, when selecting the model, a longer first cross-flow fan 2 can be selected, which can improve the air volume of the vertical air conditioner indoor unit 100 to a certain extent.

[0042] In some embodiments, see Figure 5 , Figure 6 and Figure 7 , Figure 5 yes Figure 3 A structural schematic diagram of the vertical air conditioner indoor unit 100 from another perspective. Figure 6 This is a sectional view of the vertical air conditioner indoor unit 100 in Figure 5 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 2 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 2 is also used to blow the heat-treated air out through the air outlet 12 when it rotates.

[0043] Since the first cross-flow fan 2 is located inside the air conditioner casing 1, when the first cross-flow fan 2 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 2 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.

[0044] Among them, see Figure 7The 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.

[0045] In some embodiments, see Figure 3 and Figure 4 The vertical air conditioner indoor unit 100 includes a first cover 4, which is disposed on the air conditioner casing 1.

[0046] The shape of the first cover 4 can be a disc or other possible shapes, and this embodiment does not limit this.

[0047] The first cover 4 can be detachably mounted on the air conditioner housing 1 by means of screws or other means. In this way, the first cover 4 can be easily removed from the air conditioner housing 1 to facilitate the maintenance of the components inside the air conditioner housing 1 (such as the first drive module 5 and the heat exchanger 3).

[0048] In some embodiments, see Figure 4 and Figure 8 , Figure 8 yes Figure 4 The diagram shows the structure of the first drive module 5 and the first cross-flow fan 2. The vertical air conditioner indoor unit 100 includes the first drive module 5, which is connected along the height direction between the top of the first cross-flow fan 2 and the first cover 4, and is used to drive the first cross-flow fan 2 to rotate.

[0049] Since the first drive module 5 is connected between the top of the first cross-flow fan 2 and the first cover 4 along the aforementioned height direction, the first drive module 5 can be relatively close to the first cover 4. In this way, when the first drive module 5 malfunctions and needs to be repaired, the first drive module 5 can be exposed by removing the first cover 4, which makes the repair work of the first drive module 5 very convenient.

[0050] In addition, by connecting the first drive module 5 between the top of the first cross-flow fan 2 and the first cover 4 along the aforementioned height direction, the first drive module 5 can be located at the top of the air conditioner housing 1. This makes it easy for a person to reach into the air conditioner housing 1 to disassemble the first drive module 5 and also makes it easy to take the first drive module 5 out of the air conditioner housing 1.

[0051] In some embodiments, see Figure 8 and Figure 9 , Figure 9 yes Figure 8A cross-sectional view at position BB shows that the first drive module 5 includes a stator 51, which is connected to the first cover 4, and a coil (not shown in the figure) is provided on the stator 51.

[0052] The stator 51 can be connected to the first cover 4 in various ways, such as by screws, but this embodiment does not limit this.

[0053] In some embodiments, see Figure 9 The first drive module 5 includes a rotor assembly 52. ​​The rotor assembly 52 is spaced around the axis O1 of the stator 51 and is connected to the top of the first cross-flow fan 2. The rotor assembly 52 is provided with a first magnetic element 520. When the coil is energized, it can drive the rotor assembly 52 to align with the center of the axis O1 and rotate around the axis O1.

[0054] Since the rotor assembly 52 is spaced around the axis O1 of the stator 51, and a first magnetic element 520 is provided on the rotor assembly 52, the coil on the stator 51 will be located in the magnetic field of the first magnetic element 520. When the coil on the stator 51 is located in the magnetic field of the first magnetic element 520, when the coil is energized, a magnetic force will be generated between the coil and the first magnetic element 520. This magnetic force can drive the rotor assembly 52 to align with the center of the axis O1 and rotate around the axis O1.

[0055] When the rotor assembly 52 rotates around the axis O1, since the rotor assembly 52 is connected to the top of the first cross-flow fan 2, it can drive the first cross-flow fan 2 to rotate. When the first cross-flow fan 2 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 assembly 52 is spaced around the axis O1 of the stator 51 and is installed around the periphery of the stator 51, and since the coil can drive the rotor assembly 52 to align with the center of the axis O1 when energized, there is no contact point between the rotor assembly 52 and the stator 51. In simple terms, there is a gap between the rotor assembly 52 and the stator 51 along the radial direction, and the rotor assembly 52 is suspended in the radial direction of the stator 51 relative to the stator 51. In this way, the friction between the rotor assembly 52 and the stator 51 can be reduced, thereby reducing the operating noise of the first cross-flow fan 2 while making it easier to increase the speed of the first cross-flow fan 2.

[0057] It should be noted that there are various ways to connect the rotor assembly 52 to the top of the first cross-flow fan 2. 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 9 The vertical air conditioner indoor unit 100 includes a first load-bearing module 6a, the first load-bearing module 6a includes a second magnetic component 61, and the second magnetic component 61 is disposed on the rotor assembly 52.

[0059] The second magnetic component 61 can be any magnetic component such as a magnet, a magnetite, or an electromagnet; this embodiment does not limit this.

[0060] In some embodiments, see Figure 9 The first load-bearing module 6a includes a third magnetic element 62, which is disposed on the stator 51 and is aligned with the second magnetic element 61 along the height direction. Figure 9 The third magnetic element 62 is used to provide upward (along the Z-axis direction) relative to the second magnetic element 61. Figure 9 The magnetic force in the positive direction of the Z-axis.

[0061] Since the second magnetic element 61 is disposed on the rotor assembly 52 and the third magnetic element 62 is disposed on the stator 51 and is spaced apart from the second magnetic element 61 along the height direction, the third magnetic element 62 can provide an upward magnetic force to the second magnetic element 61 along the height direction, so that the second magnetic element 61 can be suspended above the third magnetic element 62. This force can support the first cross-flow fan 2 upward along the aforementioned height direction, thereby overcoming the gravity of the first cross-flow fan 2. In this way, on the one hand, it can prevent the first cross-flow fan 2 from falling downward and breaking, and on the other hand, it can also prevent the first drive module 5 from failing due to the rotor assembly 52 moving downward relative to the stator 51 when the first cross-flow fan 2 falls downward, thus better ensuring the normal rotation of the first cross-flow fan 2.

[0062] Furthermore, since the second magnetic element 61 is disposed on the rotor assembly 52, and the third magnetic element 62 is disposed on the stator 51 and spaced apart from the second magnetic element 61 along the height direction, that is, the first load-bearing module 6a is integrated into the first drive module 5. Therefore, both the first load-bearing module 6a and the first drive module 5 can be located at the top of the first cross-flow fan 2. In this way, it is not necessary to set the first load-bearing module 6a at the bottom of the first cross-flow fan 2 to bear the weight of the first cross-flow fan 2, so that the bottom of the first cross-flow fan 2 can be a free end that can move freely along the height direction.

[0063] In this way, when the first cross-flow fan 2 expands due to heat and changes in size, the bottom end of the first cross-flow fan 2 can be released downwards. This avoids the situation where the first cross-flow fan 2 can only expand upwards due to the change in size, which would force the spacing between the second magnetic component 61 and the third magnetic component 62 to change along the height direction. This can better ensure the normal rotation of the first cross-flow fan 2.

[0064] In some embodiments, see Figure 4 , Figure 6 and Figure 9 The vertical air conditioner indoor unit 100 includes an air conditioner casing 1, a first cross-flow fan 2, a heat exchanger 3, a first cover 4, a first drive module 5, and a first load-bearing module 6a. The air conditioner casing 1 is provided with an air inlet 11 and an air outlet 12. The first cross-flow fan 2 is rotatably mounted inside the air conditioner casing 1 and extends along the height direction of the air conditioner casing 1. The heat exchanger 3 is also located inside the air conditioner casing 1. When the first cross-flow fan 2 rotates, it draws 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 2 also blows the heat-treated air out through the air outlet 12 when rotating. The first cover 4 is located on the air conditioner casing 1. The first drive module 5 is connected along the height direction between the top of the first cross-flow fan 2 and the first cover 4, and is used to drive the first cross-flow fan 2 to rotate.

[0065] See Figure 9 The first drive module 5 includes a stator 51 and a rotor assembly 52. ​​The stator 51 is connected to the first cover 4 and has coils. The rotor assembly 52 is spaced around the axis O1 of the stator 51 and connected to the top of the first cross-flow fan 2. The rotor assembly 52 has a first magnetic element 520. When the coils are energized, the rotor assembly 52 can be driven to align with the center of the axis O1 and rotate around the axis O1.

[0066] See Figure 9 The first load-bearing module 6a includes a second magnetic element 61 and a third magnetic element 62. The second magnetic element 61 is disposed on the rotor assembly 52, and the third magnetic element 62 is disposed on the stator 51 and is spaced apart from the second magnetic element 61 along the height direction. The third magnetic element 62 is used to provide the second magnetic element 61 with an upward magnetic force along the height direction.

[0067] In this embodiment, since the rotor assembly 52 is spaced around the axis O1 of the stator 51 and is sleeved around the periphery of the stator 51, and since the coil can drive the rotor assembly 52 to align with the center of the axis O1 when energized, there is no contact point between the rotor assembly 52 and the stator 51. In simple terms, the rotor assembly 52 is suspended in the radial direction of the stator 51 relative to the stator 51. This reduces the friction between the rotor assembly 52 and the stator 51, thereby making it easier to increase the speed of the first cross-flow fan 2 while reducing the operating noise of the first cross-flow fan 2.

[0068] Furthermore, since the second magnetic element 61 is disposed on the rotor assembly 52 and the third magnetic element 62 is disposed on the stator 51 and is spaced apart from the second magnetic element 61 along the height direction, the third magnetic element 62 can provide an upward magnetic force to the second magnetic element 61 along the height direction. This force can support the first cross-flow fan 2 upward along the aforementioned height direction, allowing the second magnetic element 61 to suspend above the third magnetic element 62. This force can overcome the gravity of the first cross-flow fan 2. In this way, on the one hand, it can prevent the first cross-flow fan 2 from falling and breaking, and on the other hand, it can also prevent the first drive module 5 from failing due to the rotor assembly 52 moving downward relative to the stator 51 when the first cross-flow fan 2 falls downward. This can better ensure the normal rotation of the first cross-flow fan 2.

[0069] Furthermore, since the second magnetic element 61 is disposed on the rotor assembly 52, and the third magnetic element 62 is disposed on the stator 51 and spaced apart from the second magnetic element 61 along the height direction, that is, the first load-bearing module 6a is integrated into the first drive module 5. Therefore, both the first load-bearing module 6a and the first drive module 5 can be located at the top of the first cross-flow fan 2. In this way, it is not necessary to set the first load-bearing module 6a at the bottom of the first cross-flow fan 2 to bear the weight of the first cross-flow fan 2, so that the bottom of the first cross-flow fan 2 can be a free end that can move freely along the height direction.

[0070] In this way, when the first cross-flow fan 2 expands due to heat and changes in size, the bottom end of the first cross-flow fan 2 can be released downwards. This avoids the situation where the first cross-flow fan 2 can only expand upwards due to the change in size, which would force the spacing between the second magnetic component 61 and the third magnetic component 62 to change along the height direction. This can better ensure the normal rotation of the first cross-flow fan 2.

[0071] In some embodiments, see Figure 9The rotor assembly 52 includes a rotor 521, wherein the rotor 521 is spaced around the axis O1 and sleeved around the periphery of the stator 51, and the rotor 521 is connected to the top of the first cross-flow fan 2. A first magnetic element 520 is disposed on the rotor 521. The stator 51 is provided with a first central hole 511 that penetrates the stator 51 along the height direction and is coaxial with the axis O1.

[0072] The first central hole 511 can be a round hole or a square hole, etc., and this embodiment does not limit it.

[0073] In some embodiments, the rotor assembly 52 includes a first rotating shaft 522, which is connected to the rotor 521 and coaxial with the axis O1, and the first rotating shaft 522 passes through the first central hole 511.

[0074] Since the first rotating shaft 522 is connected to the rotor 521 and is coaxial with the axis O1, and the first rotating shaft 522 passes through the first central hole 511, the hole wall of the first central hole 511 can limit the first rotating shaft 522, thereby reducing the possibility of the first rotating shaft 522 swaying significantly in the radial direction of the first rotating shaft 522. This can prevent the rotor 521 from swaying relative to the stator 51 in the radial direction of the first rotating shaft 522, thereby better ensuring the stability of the first drive module 5 and the operating accuracy of the first drive module 5.

[0075] In some embodiments, see Figure 9 The second magnetic element 61 is located above the third magnetic element 62 along the height direction, and the polarities of the two opposite ends of the second magnetic element 61 and the third magnetic element 62 are the same.

[0076] Since the polarities of the two opposite ends of the second magnetic element 61 and the third magnetic element 62 are the same, the third magnetic element 62 can provide an upward repulsive force to the second magnetic element 61 along the height direction. Furthermore, since the second magnetic element 61 is located above the third magnetic element 62 along the height direction, and since the second magnetic element 61 is disposed on the rotor assembly 52 and the third magnetic element 62 is disposed on the stator 51, the stator 51 can provide an upward supporting force to the rotor assembly 52 through the second and third magnetic elements 61 and 62. This upward supporting force can overcome the gravity acting on the first cross-flow fan 2. In this way, on the one hand, it can prevent the first cross-flow fan 2 from falling and breaking; on the other hand, it can also prevent the first drive module 5 from failing due to the rotor assembly 52 moving downwards relative to the stator 51 when the first cross-flow fan 2 falls. This better ensures the normal rotation of the first cross-flow fan 2.

[0077] In addition, since the polarities of the two opposite ends of the second magnetic component 61 and the third magnetic component 62 are the same, it can be avoided that the second magnetic component 61 and the third magnetic component 62 will not be abnormally attracted together during installation or disassembly, which could cause the user to be pinched by the magnetic components.

[0078] In some embodiments, see Figure 9 The third magnetic element 62 is disposed at the top of the stator 51, and the second magnetic element 61 is disposed on the first rotating shaft 522.

[0079] Since the third magnetic element 62 is located at the top of the stator 51 and the second magnetic element 61 is located at the first rotating shaft 522, and since the first rotating shaft 522 is connected to the rotor 521, and the rotor 521 is connected to the top of the first cross-flow fan 2, the repulsive force provided by the third magnetic element 62 to the second magnetic element 61 can act as a pulling force to pull the first cross-flow fan 2 upward, thereby achieving the purpose of preventing the first cross-flow fan 2 from falling downward and being damaged.

[0080] By placing the third magnetic element 62 at the top of the stator 51, the situation where the third magnetic element 62 is enclosed inside the rotor 521 can be avoided. Therefore, the installation and removal of the third magnetic element 62 can be carried out without interference from the rotor 521, making the installation and removal of the third magnetic element 62 more convenient.

[0081] It should be noted that the second magnetic element 61 is located above the third magnetic element 62 along the height direction. The fact that the polarities of the two opposite ends of the second magnetic element 61 and the third magnetic element 62 are the same is only one possible implementation given in this embodiment. For other possible implementations, please refer to [link / reference needed]. Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of another first drive module 5 and first cross-flow fan 2 provided in an embodiment of this application. Figure 11 yes Figure 10 In the cross-sectional view at position C, the second magnetic element 61 is located below the third magnetic element 62 along the height direction. The polarities of the two ends of the second magnetic element 61 and the third magnetic element 62 are opposite to each other. In this way, the third magnetic element 62 can provide an upward attraction to the second magnetic element 61 along the height direction. This attraction acts as a pulling force to pull the first cross-flow fan 2 upward, thereby achieving the purpose of preventing the first cross-flow fan 2 from falling downward and being damaged.

[0082] In some embodiments, see Figure 9 In order to better fix the second magnetic element 61 to the first rotating shaft 522, in some embodiments, the rotor assembly 52 further includes a first limiting element 523, which is disposed on the first rotating shaft 522.

[0083] The first limiting member 523 mentioned above can be a shoulder or a snap ring, etc., and this embodiment does not limit it.

[0084] In some embodiments, see Figure 9 The rotor assembly 52 also includes a second limiting member 524, which is disposed on the first rotating shaft 522 and spaced apart from the first limiting member 523 along the height direction. The second magnetic member 61 is sleeved on the first rotating shaft 522 and is limited between the first limiting member 523 and the second limiting member 524.

[0085] Since the second magnetic element 61 is sleeved on the first rotating shaft 522 and is limited between the first limiting element 523 and the second limiting element 524, the first limiting element 523 and the second limiting element 524 can limit the second magnetic element 61 from both sides along the height direction, thereby preventing the second magnetic element 61 from swaying relative to the first rotating shaft 522 along the height direction.

[0086] The second limiting member 524 mentioned above can be a shoulder or a snap ring, etc., and this embodiment does not limit it.

[0087] In some embodiments, see Figure 9 The first limiting member 523 is located above the second limiting member 524 along the height direction, and the first limiting member 523 is detachably provided.

[0088] Since the first limiting member 523 is detachable, when it is necessary to remove the second magnetic member 61, simply remove the first limiting member 523, and then the second magnetic member 61 can be easily removed from the first rotating shaft 522, making the installation and removal of the second magnetic member 61 very convenient.

[0089] In addition, since the first limiting member 523 is located above the second limiting member 524 along the height direction, the first limiting member 523 will be farther away from the first cross-flow fan 2 than the second limiting member 524. This can avoid the first cross-flow fan 2 interfering with the disassembly of the first limiting member 523, making the disassembly and installation of the first limiting member 523 more convenient.

[0090] In some embodiments, see Figure 9 The first load-bearing module 6a also includes a mounting base 63, which includes an end cap 631. The end cap 631 is sleeved on the first rotating shaft 522, located above the third magnetic element 62 and spaced apart from the third magnetic element 62. The second magnetic element 61 is disposed on the side of the end cap 631 facing the third magnetic element 62.

[0091] When the mounting base 63 also includes an end cap 631, by placing the second magnetic element 61 on the side of the end cap 631 facing the third magnetic element 62, the end cap 631 can serve as a base for mounting the second magnetic element 61, making the mounting of the second magnetic element 61 more secure and stable.

[0092] The second magnetic component 61 and the end cap 631 can be either separate or integrated. When the second magnetic component 61 and the end cap 631 are integrated, they can form a single large magnetic component.

[0093] When the second magnetic component 61 and the end cap 631 are integrated, the number of parts of the first load-bearing module 6a can be reduced to a certain extent, thus reducing the installation complexity of the first load-bearing module 6a.

[0094] Both the end cap 631 and the second magnetic element 61 can be ring-shaped structures.

[0095] In some embodiments, see Figure 9 The mounting base 63 includes a surrounding portion 632, wherein the surrounding portion 632 is disposed around the periphery of the end cap portion 631 and spaced around the peripheral wall of the third magnetic member 62.

[0096] By positioning the surrounding portion 632 around the peripheral wall of the third magnetic element 62, the surrounding portion 632 serves two purposes: firstly, it protects the third magnetic element 62, thereby extending its service life; secondly, the interaction between the surrounding portion 632 and the third magnetic element 62 provides a limiting effect, preventing the mounting base 63 from wobbling significantly relative to the third magnetic element 62 along the radial direction of the first rotating shaft 522. Furthermore, the surrounding portion 632 also functions as a magnetic shield, preventing the magnetism of the third magnetic element 62 and the second magnetic element 61 from adversely affecting the first drive module, thus better ensuring the normal operation of the first drive module.

[0097] The end cap portion 631 and the surrounding portion 632 can be an integral structure or a separate structure; this embodiment does not limit this.

[0098] The material of the aforementioned surrounding portion 632 can be low-carbon steel or other possible materials, and this embodiment does not limit this.

[0099] In some embodiments, only Figure 9 The first drive module 5 also includes a first bearing 53 and a first buffer 54. The first bearing 53 is sleeved on the first rotating shaft 522, and the first buffer 54 is located in the gap between the hole wall of the first central hole 511 and the first bearing 53.

[0100] Since the first bearing 53 is sleeved on the first rotating shaft 522 and the first buffer 54 is located in the gap between the hole wall of the first central hole 511 and the first bearing 53, on the one hand, under the cooperation of the first central hole 511 and the first bearing 53, the first rotating shaft 522 and the first central hole 511 can be aligned, and the stator 51 and the rotor 521 can be aligned. This can better ensure that the gap between the rotor 521 and the stator 51 along the radial direction of the stator 51 can remain stable, thereby improving the stability of the operation of the first drive module 5 and better avoiding frictional noise between the rotor 521 and the stator 51.

[0101] On the other hand, since the first buffer 54 is located in the gap between the hole wall of the first central hole 511 and the first bearing 53, the contact between the first bearing 53 and the hole wall of the first central hole 511 can be a flexible contact. On the one hand, the collision noise between the first bearing 53 and the hole wall of the first central hole 511 can be reduced. On the other hand, the installation accuracy requirements of the first bearing 53 and the first rotating shaft 522 when installed into the first central hole 511 can also be reduced.

[0102] The first buffer 54 can be implemented in various ways. In one possible implementation, see [link to relevant documentation]. Figure 9 The first buffer element 54 is a flexible ring, which is sleeved on the first bearing 53.

[0103] When the first buffer 54 is a flexible ring, since the flexible ring is sleeved on the first bearing 53, the flexible ring can wrap around the first bearing 53 along the peripheral wall of the first bearing 53, so that the entire peripheral wall of the first bearing 53 will not make hard contact with the hole wall of the first central hole 511. This can better reduce the collision noise between the first bearing 53 and the hole wall of the first central hole 511. On the other hand, it can also further reduce the installation accuracy requirements of the first bearing 53 and the first rotating shaft 522 when they are installed in the first central hole 511.

[0104] Specifically, the aforementioned flexible ring can be a rubber ring, a silicone ring, or a polyurethane ring, etc., and this embodiment does not limit this.

[0105] In some embodiments, see Figure 12 , Figure 12 yes Figure 4 The diagram shows the structure of the vertical air conditioner indoor unit 100 after disassembly and disassembly from another perspective. The vertical air conditioner indoor unit 100 also includes a volute 2a, which is located inside the air conditioner housing 1. The first cross-flow fan 2 is rotatably disposed inside the volute 2a, and the bottom end of the first cross-flow fan 2 is spaced apart from the volute 2a along the height direction.

[0106] By positioning the bottom of the first cross-flow fan 2 at a distance from the volute 2a, a gap can be created between them. This gap allows the first cross-flow fan 2 to deform. As a result, when the first cross-flow fan 2 expands due to heat and changes in size, the bottom of the first cross-flow fan 2 can be released downwards. This avoids the situation where the first cross-flow fan 2 can only expand upwards due to changes in size, which would force a change in the distance between the second magnetic component 61 and the third magnetic component 62 along the height direction. This better ensures the normal rotation of the first cross-flow fan 2.

[0107] In some embodiments, see Figure 12 The vertical air conditioner indoor unit 100 also includes a rotating module 8a, and the bottom end of the first cross-flow fan 2 is rotatably mounted on the air conditioner casing 1 via the rotating module 8a.

[0108] When the bottom end of the first cross-flow fan 2 is rotatably mounted on the air conditioner housing 1 via the rotating module 8a, on the one hand, the rotating module 8a can fix the bottom end of the first cross-flow fan 2, thereby preventing the bottom end of the first cross-flow fan 2 from swaying left and right; on the other hand, the rotating module 8a can guide the rotation of the first cross-flow fan 2, making the first cross-flow fan 2 more stable and smooth when rotating.

[0109] In some embodiments, see Figure 12 The bottom end of the first cross-flow fan 2 may be provided with a second rotating shaft 21. The rotating module 8a includes a second bearing 81a, which is disposed on the air conditioner housing 1. The second rotating shaft 21 is slidably inserted through the second bearing 81a along the height direction.

[0110] In some embodiments, see Figure 4 The vertical air conditioner indoor unit 100 also includes a second cross-flow fan 7. The air conditioner housing 1 defines a first fan duct 13 and a second fan duct 14. Both the first fan duct 13 and the second fan duct 14 are connected to the air inlet 11. The first cross-flow fan 2 is rotatably disposed in the first fan duct 13, and the second cross-flow fan 7 is rotatably disposed in the second fan duct 14. The second cross-flow fan 7 and the first cross-flow fan 2 are arranged side by side along the width direction of the air conditioner housing 1.

[0111] By arranging the second cross-flow fan 7 and the first cross-flow fan 2 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 7 and the first cross-flow fan 2 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.

[0112] 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 13, 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 14.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] In some embodiments, see Figure 2 The 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] In some embodiments, see Figure 3 and Figure 4 The vertical air conditioner indoor unit 100 includes a second cover 8, which is disposed on the air conditioner casing 1.

[0122] The structure of the second cover 8 can be the same as that of the first cover 4 in the above embodiments. For details, please refer to the description of the first cover 4 in the above embodiments. This embodiment will not repeat the description here.

[0123] In some embodiments, see Figure 4 The vertical air conditioner indoor unit 100 includes a second drive module 9, which is connected along the height direction between the top of the second cross-flow fan 7 and the second cover 8, and is used to drive the second cross-flow fan 7 to rotate.

[0124] The structure of the second driving module 9 can be the same as that of the first driving module 5 described above. For details, please refer to the description of the first driving module 5 in the above embodiments. This embodiment will not repeat the description here.

[0125] In some embodiments, see Figure 2 and Figure 4 When the first cross-flow fan 2 rotates, it can draw indoor air into the first fan duct 13 through the air inlet 11. The first cross-flow fan 2 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 rotating. When the second cross-flow fan 7 rotates, it can draw indoor air into the second fan duct 14 through the air inlet 11. The second cross-flow fan 7 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 rotating.

[0126] 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.

[0127] In addition, when the vertical air conditioner indoor unit 100 also includes a second cross-flow fan 7, 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.

[0128] In some embodiments, the vertical air conditioner indoor unit 100 further includes a second load-bearing module (not shown in the figure). The second load-bearing module can be disposed on the second drive module 9. Specifically, the way in which the second load-bearing module is disposed on the second drive module 9 can be the same as or similar to the way in which the first load-bearing module 6a is disposed on the first drive module 5. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0129] 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.
