[0046] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides an indoor unit 10 of an air conditioner, including a housing 20, an air supply fan assembly 30, a first fan assembly 40 and a controller.

[0047] Combination Figure 1 and Figure 3As shown, the shell 20 is constructed with an air duct 21; the air supply fan assembly 30 includes air supply fan blades 31, which are arranged in the air duct 21 for indoor air supply; the first fan assembly 40 includes a first fan blade 41 and a first motor connected to each other, the first fan blade 41 is arranged in the air duct 21, and the first fan blade 41 is arranged corresponding to the air supply fan blade 31; the controller is connected to the first motor and is configured to control the first motor to switch between a power generation mode and an electric mode; wherein, when the first motor is in the power generation mode, the wind generated by the rotation of the air supply fan blades 31 drives the first fan blades 41 to rotate, so that the first motor generates electricity; when the first motor is in the electric mode, the first motor drives the first fan blades 41 to rotate to supply air to the room.

[0048] The indoor unit 10 controls the first motor to switch between the power generation mode and the electric mode through a controller. When the first motor is in the power generation mode, the first motor operates as a generator. A portion of the air volume generated by the air supply fan blades 31 is discharged from the air outlet 22 for indoor air supply. The remaining air volume generated by the air supply fan blades 31 can drive the first blades 41 to rotate, converting wind energy into mechanical energy. The rotation of the first blades 41 can drive the first motor to operate, so that the first generator generates electricity and converts mechanical energy into electrical energy. In this way, it is possible to avoid the disturbance of excess air volume in the air duct 21, thereby avoiding the waste of air volume in the air duct 21.

[0049] When the first motor is in the electric mode, the first motor operates as a motor. The first motor can consume electric energy to drive the first fan blade 41 to rotate and supply air to the room. At this time, the first fan blade 41 and the air supply fan blade 31 jointly supply air to the room, which can increase the air supply volume and improve the cooling or heating effect.

[0050] The indoor unit 10 of the air conditioner provided by the embodiment of the present disclosure is adopted, and the air supply fan blade 31 and the first fan blade 41 are both arranged in the air duct 21. The wind generated by the rotation of the air supply fan blade 31 drives the first fan blade 41 to rotate, and the excess air volume generated during the air supply of the air supply fan blade 31 can be used to generate electricity. In this way, the utilization rate of the air volume in the air duct 21 of the indoor unit 10 can be improved, and energy loss can be reduced, thereby improving the operating efficiency of the air supply fan assembly 30. At the same time, the first motor has a power generation mode and an electric mode, so that the first fan assembly 40 can not only provide air volume, but also play a role in power generation, thereby improving the energy efficiency of the air conditioner. In addition, the first fan assembly 40 is arranged in the air duct 21, which can make full use of the space in the air duct 21 and avoid additional occupation of the volume of the air conditioner. In this way, the air conditioner can increase the power generation function while maintaining the original volume, thereby improving the space utilization efficiency.

[0051] Optionally, combined Figure 1 and Figure 3As shown, the indoor unit 10 of the air conditioner also includes a second fan assembly 50, the second fan assembly 50 includes a connected second fan blade 51 and a second motor, the second fan blade 51 is arranged in the air duct 21, and the second fan blade 51 is arranged corresponding to the supply fan blade 31, the second motor is connected to the controller, and the controller is also configured to control the second motor to switch between the power generation mode and the electric mode; wherein, when the second motor is in the power generation mode, the wind generated by the rotation of the supply fan blade 31 drives the second fan blade 51 to rotate, so that the second motor generates electricity; when the second motor is in the electric mode, the second motor drives the second fan blade 51 to rotate to supply air to the room.

[0052] The second fan assembly 50 can not only provide air volume, but also generate electricity. The indoor unit 10 is provided with two sets of dual-function fan assemblies, namely the first fan assembly 40 and the second fan assembly 50. In the power generation mode, the excess air volume generated by the air supply fan blades 31 can be fully utilized to generate electricity. The two sets of dual-function fan assemblies can generate electricity or supply air at the same time, or they can generate electricity or supply air at different times, which can more effectively improve the utilization efficiency of the wind energy generated by the air supply fan assembly 30. By controlling the first motor and the second motor to switch between different modes through the controller, the air volume can be flexibly adjusted according to actual needs, the air volume distribution can be optimized, and the comfort and energy-saving effect of the air conditioner can be improved. At the same time, combined with Figure 5-7 As shown, the first blade 41 and the second blade 51 can also generate air volume when they are passively rotated, and the wind generated by the passive rotation can be used for heat exchange of the evaporator.

[0053] Optionally, the indoor unit 10 of the air conditioner further includes an energy storage device, which is connected to the first fan and / or the second fan to store the electric energy generated by the first fan and / or the second fan in the power generation mode.

[0054] The electric energy generated by the first fan and / or the second fan in the power generation mode is stored in the energy storage device, and the electric energy in the energy storage device can be called upon as needed. The first fan assembly 40 and / or the second fan assembly 50 can be used to generate electricity and store energy during periods of low electricity prices (such as at night), and the stored electric energy can be used to work during periods of peak electricity prices (such as during the day). This reduces electricity bills and can also save energy and reduce emissions. The energy storage device is charged during low electricity consumption periods and discharged during peak electricity consumption periods, which can reduce electricity demand during peak periods and achieve optimal allocation of power resources. The energy storage device can be an energy storage battery. It can be understood that the electric energy generated by the first motor and / or the second motor in the power generation mode can also be directly used to power other components of the air conditioner.

[0055] Optionally, the indoor unit 10 of the air conditioner further includes a sensor, which is used to detect the wind speed and air volume in the air duct 21, and transmit the detection data to the controller to adjust the operating state of the first fan and / or the second fan.

[0056] The wind speed and air volume in the air duct 21 are detected by the sensor, and the data is transmitted to the controller. The controller adjusts the operating state of the first fan and / or the second fan according to the detected data, so that the controller can more accurately adjust the working state of the first fan and / or the second fan. In this way, dynamic air volume control can be effectively achieved, the air supply effect and the power generation effect can be balanced, and the air conditioner can adjust the air volume and wind speed according to actual needs to improve the user's comfort. At the same time, the use of sensors enables the air conditioning system to automatically respond to environmental changes, realize intelligent control, and improve the automation level of the system.

[0057] Optionally, combined Figure 1 and Figure 5-7 As shown, the indoor unit 10 of the air conditioner also includes a first wind shield 60, which is arranged on the outside of the first fan blade 41, and the first wind shield 60 can move between a first position and a second position relative to the first fan blade 41; wherein, in the first position, the wind field of the first fan blade 41 and the supply fan blade 31 are separated, and in the second position, the wind field of the first fan blade 41 and the supply fan blade 31 are connected.

[0058] Combination Figure 7 As shown, the first wind shielding portion 60 is located at the first position, and the first wind shielding portion 60 blocks between the first fan blade 41 and the fan blade 31, and can separate the wind field of the first fan blade 41 and the fan blade 31. Figure 5 and Figure 6 As shown, the first wind shielding portion 60 is located at the second position, there is no shielding between the first fan blade 41 and the fan blade 31, and the wind generated by the rotation of the fan blade 31 can flow along the Figure 5 and Figure 6 The air blows toward the first fan blade 41 in the direction indicated by the middle arrow, thereby driving the first fan blade 41 to rotate and causing the first motor to generate electricity.

[0059] When the first motor is in the electric mode, the first blade 41 is in the air supply state, and the air supply blade 31 and the first blade 41 both rotate to generate a wind field. The first wind shield 60 moves to the first position, which can separate the wind field of the first blade 41 and the air supply blade 31, and avoid the wind field interference between the first blade 41 and the air supply blade 31, thereby improving the air supply effect of the first fan assembly 40 and the air supply fan assembly 30.

[0060] When the first motor is in the power generation mode, the first wind shield 60 moves to the second position, so that the wind field of the first fan blade 41 and the air supply fan blade 31 are connected, so that the wind energy generated by the rotation of the air supply fan blade 31 can be fully utilized to generate electricity. By moving the first wind shield 60 between the first position and the second position, the wind field can be dynamically managed according to the different needs of power generation or air supply of the first fan assembly 40, reducing air volume waste and improving air volume utilization.

[0061] Optionally, the first wind shielding portion 60 can also separate the wind field of the first blade 41 and the wind field of the second blade 51 when in the first position.

[0062] When the first wind shield 60 is in the first position, the first motor is in electric mode, and the first fan assembly 40 is in air supply state. The first wind shield 60 separates the wind field of the first blade 41 and the air supply blade 31, and can also separate the wind field of the first blade 41 and the second blade 51, which can effectively avoid the ineffective mixing and loss of the air volume generated by the first blade 41 in the air duct 21, and improve the air supply efficiency of the first fan assembly 40. It can be understood that the first wind shield 60 can also separate the wind field of the first blade 41 and the second blade 51 when in the second position.

[0063] Optionally, combined Figure 1 and Figure 3 As shown, the first wind shield 60 includes a first rack 61 and a first gear 62. The first rack 61 is blocked on the outside of the first fan blade 41 and can move relative to the first fan blade 41. The first gear 62 is transmission connected to the first rack 61 to drive the first rack 61 to move between the first position and the second position.

[0064] The first rack 61 can be driven to move by the rotation of the first gear 62. When the first rack 61 moves to the first position, it blocks between the first blade 41 and the fan blade 31, and can separate the wind field of the first blade 41 and the fan blade 31. When the first rack 61 moves to the second position, the wind field of the first blade 41 and the fan blade 31 can be connected. The meshing transmission of the first gear 62 and the first rack 61 can improve the accuracy and flexibility of the movement of the first wind shield 60, so that the first rack 61 can stop accurately at the first position or the second position, thereby improving the accuracy of controlling the separation or connection of the wind field.

[0065] Optionally, the height of the first rack 61 is greater than or equal to the height of the first blade 41 .

[0066] The height of the first rack 61 is greater than or equal to the height of the first blade 41, which can effectively block the wind field of the first blade 41 and prevent the first blade 41 from being disturbed by the external wind field. When the first rack 61 moves to the first position, it can completely separate the wind fields of the first blade 41 and the fan blade 31 to prevent airflow mixing.

[0067] Optionally, combined Figure 1 , Figure 3 and Figure 4As shown, the indoor unit of the air conditioner also includes a first guide seat 63, which extends along the circumference of the first fan blade 41; wherein the first guide seat 63 is provided with a first guide portion 631, and the first rack 61 is provided with a first guide matching portion 611, and the first guide portion 631 cooperates with the first guide matching portion 611 to guide the first rack 61 to move between the first position and the second position.

[0068] The first guide seat 63 extends along the circumference of the first blade 41, and can guide the first rack 61 to move between the first position and the second position along the circumference of the first blade 41. Through the cooperation of the first guide portion 631 and the first guide matching portion 611, the guiding accuracy of the movement of the first wind shielding portion 60 can be improved, and the accuracy of the first wind shielding portion 60 during the movement process can be improved. At the same time, the first guide seat 63 can also provide a stable structural support for the first rack 61, improve the stability of the first rack 61, and reduce the vibration caused by the wind.

[0069] Optionally, combined Figure 1 and Figure 5-7 As shown, the indoor unit 10 of the air conditioner also includes a second wind shield 70, which is arranged on the outside of the second fan blade 51, and the second wind shield 70 can move between a third position and a fourth position relative to the second fan blade 51; wherein, in the third position, the wind field of the second fan blade 51 and the supply fan blade 31 are separated, and in the fourth position, the wind field of the second fan blade 51 and the supply fan blade 31 are connected.

[0070] Combination Figure 6 and Figure 7 As shown, the second wind shielding portion 70 is located at the third position, and the second wind shielding portion 70 is shielded between the second fan blade 51 and the fan blade 31, and can separate the wind field of the second fan blade 51 and the fan blade 31. Figure 5 As shown, the second wind shield 70 is located at the fourth position, there is no shielding between the second fan blade 51 and the fan blade 31, and the wind generated by the rotation of the fan blade 31 can flow along the Figure 5 The air blows toward the second fan blade 51 in the direction indicated by the middle arrow, thereby driving the second fan blade 51 to rotate and causing the second motor to generate electricity.

[0071] When the second motor is in the electric mode, the second blade 51 is in the air supply state, and the air supply blade 31 and the second blade 51 both rotate to generate a wind field. The second wind shield 70 moves to the third position, which can separate the wind field of the second blade 51 and the air supply blade 31, and avoid the wind field interference between the second blade 51 and the air supply blade 31, thereby improving the air supply effect of the second fan assembly 50 and the air supply fan assembly 30.

[0072] When the second motor is in the power generation mode, the second wind shield 70 moves to the fourth position, so that the wind field of the second fan blade 51 and the air supply fan blade 31 are connected, so that the wind energy generated by the rotation of the air supply fan blade 31 can be fully utilized to generate electricity. By moving the second wind shield 70 between the third position and the fourth position, the wind field can be dynamically managed according to the different needs of power generation or air supply of the second fan assembly 50, reducing air volume waste and improving air volume utilization.

[0073] Optionally, the second wind shield 70 can also separate the wind field of the first blade 41 and the wind field of the second blade 51 when in the third position.

[0074] When the second wind shield 70 is in the third position, the second motor is in electric mode, and the second fan assembly 50 is in air supply state. The second wind shield 70 separates the wind field of the second blade 51 and the air supply blade 31, and can also separate the wind field of the first blade 41 and the second blade 51, so that the ineffective mixing and loss of the air volume generated by the second blade 51 in the air duct 21 can be effectively avoided, thereby improving the air supply efficiency of the second fan assembly 50. It can be understood that the first and second wind shields can also separate the wind field of the first blade 41 and the second blade 51 when they are in the fourth position.

[0075] Optionally, combined Figure 1 and Figure 3 As shown, the second wind shield 70 includes a second rack 71 and a second gear 72. The second rack 71 is blocked on the outside of the second fan blade 51 and can move relative to the second fan blade 51. The second gear 72 is transmission connected to the second rack 71 to drive the second rack 71 to move between the third position and the fourth position.

[0076] The second rack 71 can be driven to move by the rotation of the second gear 72. When the second rack 71 moves to the third position, it blocks between the second blade 51 and the fan blade 31, and can separate the wind field of the second blade 51 and the fan blade 31. When the second rack 71 moves to the fourth position, the wind field of the second blade 51 and the fan blade 31 can be connected. The meshing transmission of the second gear 72 and the second rack 71 can improve the accuracy and flexibility of the movement of the second wind shield 70, so that the second rack 71 can stop accurately at the third position or the fourth position, thereby improving the accuracy of controlling the separation or connection of the wind field.

[0077] Optionally, the height of the second rack 71 is greater than or equal to the height of the second blade 51 .

[0078] The height of the second rack 71 is greater than or equal to the height of the second blade 51, which can effectively block the wind field of the second blade 51 and prevent the second blade 51 from being disturbed by the external wind field. When the second rack 71 moves to the third position, the wind field of the second blade 51 and the fan blade 31 can be completely separated to prevent airflow mixing.

[0079] Optionally, combined Figure 1 and Figure 3 As shown, the indoor unit of the air conditioner also includes a second guide seat 73, which extends along the circumference of the second fan blade 51; wherein the second guide seat 73 is provided with a second guide portion, and the second rack 71 is provided with a second guide matching portion, and the second guide portion cooperates with the second rack 71 to guide the second rack 71 to move between the third position and the fourth position.

[0080] The second guide seat 73 extends along the circumference of the second blade 51, and can guide the second rack 71 to move between the third position and the fourth position along the circumference of the second blade 51. Through the cooperation of the second guide portion and the second guide matching portion, the guiding accuracy of the movement of the second wind shielding portion 70 can be improved, and the accuracy of the second wind shielding portion 70 during the movement process can be improved. At the same time, the second guide seat 73 can also provide a stable structural support for the second rack 71, improve the stability of the second rack 71, and reduce the vibration caused by the wind.

[0081] The matching structure between the first wind shield 60 and the first guide seat 63 and the matching structure between the second wind shield 70 and the second guide seat 73 can adopt the same structure. The matching structure between the first wind shield 60 and the first guide seat 63 is taken as an example for description.

[0082] Optionally, combined Figure 1 and Figure 3 As shown, the first guide seat 63 extends in an arc shape along the circumference of the first blade 41, and the first rack 61 is driven to move along the arc through the rotation of the first gear 62.

[0083] The first rack 61 moves smoothly and continuously along the arc-shaped first guide seat 63 , which can reduce friction and wear during the movement.

[0084] Optionally, combined Figure 4 As shown, one of the first guide portion 631 and the first guide matching portion 611 is a first slide groove 632 , and the other is a first slider 612 . The first slider 612 is embedded in the first slide groove 632 , and the first slider 612 can move relative to the first slide groove 632 .

[0085] The first guide portion 631 may be the first slider 612, and the first guide matching portion 611 may be the first slide groove 632. The first guide portion 631 may be the first slide groove 632, and the first guide matching portion 611 may be the first slider 612. This application takes the first guide portion 631 as the first slide groove 632, and the first guide matching portion 611 as the first slider 612 as an example. The first slider 612 is arranged at the end of the first rack 61 facing the first guide seat 63, the first slider 612 is inserted into the first slide groove 632, and the first slider 612 can move along the first slide groove 632 between the first position and the second position. At the same time, when the first slider 612 is located in the first slide groove 632, the first slide groove 632 can also play a certain limiting effect on the first slider 612, limiting the first slider 612 from moving within the range of the first slide groove 632.

[0086] Optionally, combined Figure 1 As shown, the indoor unit 10 of the air conditioner further includes a chassis 11 , which is disposed at the bottom of the housing 20 and connected to the housing 20 , and the first guide seat 63 and / or the second guide seat 73 are disposed on the chassis 11 .

[0087] The first guide seat 63 and / or the second guide seat 73 are arranged on the chassis 11, which can optimize the internal space layout of the indoor unit 10, make the air duct 21 design more compact, and thus improve the space utilization. At the same time, the chassis 11 can also provide a stable installation platform for the first guide seat 63 and / or the second guide seat 73, thereby improving the stability of the first guide seat 63 and / or the second guide seat 73.

[0088] Optionally, combined Figure 4 As shown, the first guide seat 63 is provided with a first limiting portion 633, and the first rack 61 is provided with a first limiting matching portion 613. The first limiting portion 633 cooperates with the first limiting matching portion 613 to prevent the first rack 61 from separating from the first guide seat 63 during movement.

[0089] The first limiting portion 633 cooperates with the first limiting matching portion 613 to effectively limit the first rack 61 to the first guide seat 63 , thereby improving the stability and accuracy of the movement of the first rack 61 .

[0090] Optionally, the second guide seat 73 is provided with a second limiting portion, and the second rack 71 is provided with a second limiting matching portion, and the second limiting portion cooperates with the second limiting matching portion to prevent the second rack 71 from detaching from the second guide seat 73 during movement.

[0091] The second limiting portion cooperates with the second limiting matching portion to effectively limit the second rack 71 to the second guide seat 73 , thereby improving the stability and accuracy of the movement of the second rack 71 .

[0092] The matching structure between the first position limiting portion 633 and the first position limiting matching portion 613 and the matching structure between the second position limiting portion and the second position limiting matching portion can adopt the same position limiting matching structure.

[0093] Optionally, combined Figure 4 As shown, one of the first limiting portion 633 and the first limiting matching portion 613 is a first T-shaped groove, and the other is a first T-shaped protrusion. The first T-shaped protrusion is embedded in the first T-shaped groove, and the first T-shaped protrusion can move along the first T-shaped groove.

[0094] The present application takes the first limiting portion 633 as the first T-slot and the first limiting matching portion 613 as the first T-shaped protrusion as an example. The longitudinal section of the first T-slot is a T-shaped groove, and the longitudinal section of the first T-shaped protrusion is a T-shaped protrusion. The T-shape here refers to a T-shape or a T-shaped structure. The first T-slot forms a semi-enclosed limiting structure, and the first T-shaped protrusion is embedded in the first T-slot, so that the first rack 61 is installed in a semi-enclosed limiting space, so that the first rack 61 is limited in the upper, lower, left and right directions. This can prevent the first rack 61 from accidentally shifting in any direction, thereby improving the stability of the structure. At the same time, the matching structure of the first T-slot and the first T-shaped protrusion can not only play a limiting role, but also play a guiding role through the extension direction of the first T-slot. Combining the guiding structure with the limiting structure can make the structure compact and simplify the assembly process.

[0095] Optionally, combined Figure 4 As shown, the first rack 61 is provided with a first protrusion 615 , the first protrusion 615 protrudes toward the first guide seat 63 , and the first protrusion 615 abuts against the first base.

[0096] By setting the first protrusion 615, the contact area between the first rack 61 and the first guide seat 63 can be reduced, thereby reducing friction and improving the movement effect and durability of the first rack 61. The first protrusion 615 can be a semicircular protrusion, which can more effectively reduce friction. In the case where the first rack 61 is provided with the first slider 612, the first protrusion 615 is provided on the first slider 612.

[0097] Optionally, combined Figure 4 As shown, there are multiple first protrusions 615, and the multiple first protrusions 615 are evenly distributed between the first rack 61 and the first guide seat 63. This can reduce friction and improve movement stability.

[0098] Optionally, the second rack 71 is provided with a second protrusion, the second protrusion protrudes toward the second guide seat 73, and the second protrusion abuts against the second base.

[0099] By setting the second protrusion, the contact area between the second rack 71 and the second guide seat 73 can be reduced, thereby reducing friction and improving the movement effect and durability of the second rack 71. The second protrusion can be a semicircular protrusion, which can more effectively reduce friction. In the case where the second rack 71 is provided with a second slider, the second protrusion is provided on the second slider.

[0100] Optionally, there are multiple second protrusions, and the multiple second protrusions are evenly distributed between the second rack 71 and the second guide seat 73. This can reduce friction and improve movement stability.

[0101] Optionally, combined Figure 2 As shown, the housing 20 is provided with an air outlet 22 , and the indoor unit 10 of the air conditioner further comprises a panel 12 , which covers the air outlet 22 and is detachably connected to the housing 20 .

[0102] The air duct 21 is located in the housing 20, and the air supply fan assembly 30, the first fan assembly 40, and the second fan assembly 50 are all located in the air duct 21. The panel 12 is provided to cover the air outlet 22, and can shield the air supply fan assembly 30, the first fan assembly 40, and the second fan assembly 50, thereby improving the aesthetics of the indoor unit 10. By removing the panel, it is also convenient to clean and repair the internal components of the indoor unit 10.

[0103] Optionally, combined Figure 2 As shown, the panel 12 is provided with an air inlet 121 so that air can enter the air duct from the room through the air inlet 121 .

[0104] Directly guiding the indoor air to flow into the air duct through the air inlet 121 can improve the efficiency of air circulation, thereby effectively adjusting the indoor air.

[0105] Optionally, combined Figure 1 As shown, the indoor unit of the air conditioner further includes an evaporator 13 , which is disposed in the housing 20 , and the evaporator 13 is surrounded by the outside of the air supply fan assembly 30 , the first fan assembly 40 and the second fan assembly 50 .

[0106] The evaporator 13 is arranged outside the air supply fan assembly 30, the first fan assembly 40 and the second fan assembly 50, which can more effectively cool or heat the air in the air duct, thereby improving the cooling and heating effects of the air conditioner. At the same time, this can also save space inside the housing 20.

[0107] Optionally, the controller is configured to control the first motor and the second motor to switch between power generation mode and electric mode according to the air supply volume demand; when the air supply volume demand is low, the first motor and the second motor are controlled to switch to power generation mode; when the air supply volume demand is medium, the first motor is controlled to switch to power generation mode, and the second motor is controlled to switch to electric mode; when the air supply volume demand is high, the first motor and the second motor are controlled to switch to electric mode.

[0108] The controller can meet different air volume requirements by controlling the different working modes of the first motor and the second motor. The controller intelligently controls the motor mode switching according to the air volume requirements, which can achieve intelligent response to air volume requirements and improve the energy efficiency of the air conditioner and user comfort.

[0109] When the air volume demand is low, the dual motor power generation state is turned on. The controller controls the first motor and the second motor to switch to the power generation mode, so that the wind generated by the rotation of the air supply fan blades 31 drives the first blades 41 and the second blades 51 to rotate at the same time, so that the wind energy generated by the air supply fan blades 31 in the air duct 21 can be fully utilized to generate electricity.

[0110] When the air supply volume demand is a medium air volume, the single motor power generation state is turned on. The controller controls the first motor to switch to the power generation mode, so that the wind generated by the rotation of the supply fan blades 31 drives the first fan blades 41 to rotate, and controls the second motor to switch to the electric mode, so that the second motor drives the second fan blades 51 to rotate to supply air to the room. When the first motor is in the power generation mode, the wind energy generated by the rotation of the supply fan blades 31 can be used to generate electricity, realize energy recovery and reuse, and improve the energy efficiency of the system. When the second motor is in the electric mode, it can provide a stable air volume supply together with the supply fan blades 31 to meet the demand for medium air volume while maintaining the stability of the indoor temperature.

[0111] When the air supply air volume demand is high, the controller controls the first motor and the second motor to switch to the electric mode, so that the first motor drives the first fan blade 41 to rotate to supply air to the room, and the second motor drives the second fan blade 51 to rotate to supply air to the room. When the first motor and the second motor are both in the electric mode, a greater air supply capacity can be provided, so that when the air volume demand is high, sufficient air circulation can be obtained in the room, and the indoor temperature can be quickly adjusted.

[0112] Optionally, in the case where the indoor unit 10 includes the first wind shield 60 and the second wind shield 70, Figure 5 As shown, when the air supply volume demand is low, the first wind shield 60 moves to the second position, and the second wind shield moves to the fourth position, so that the wind field of the first blade 41 and the air supply blade 31 are connected, and the wind field of the second blade 51 and the air supply blade 31 are connected; combined Figure 6As shown, when the air supply volume demand is a medium air volume, the first wind shield 60 moves to the second position, and the second wind shield moves to the third position, so that the wind field of the first blade 41 and the air supply blade 31 are connected, and the wind field of the second blade 51 and the air supply blade 31 are separated; Figure 7 As shown, when the air supply volume demand is high, the first wind shield 60 moves to the first position and the second wind shield moves to the third position, so that the wind field of the first fan blade 41 and the supply fan blade 31 are separated, and the wind field of the second fan blade 51 and the supply fan blade 31 are separated.

[0113] The controller adjusts the positions of the first wind shield 60 and the second wind shield 70 according to different air supply volume requirements, and can accurately control the connection or separation of the wind field between the first fan blade 41 and the air supply fan blade 31, and between the second fan blade 51 and the air supply fan blade 31. When the air volume requirement is low, unnecessary energy consumption is reduced by connecting the air field. When the air volume requirement is high, sufficient air volume supply is ensured by separating the wind field, thereby improving energy utilization efficiency.

[0114] Exemplarily, when the air supply volume demand is low, the dual-motor power generation state is turned on. The supply fan blades 31 rotate clockwise, the first rack 61 moves to a position that connects the wind field of the first blades 41 and the supply fan blades 31, and the second rack 71 moves to a position that connects the wind field of the second blades 51 and the supply fan blades 31, so that the wind field of the supply fan blades 31 can be unobstructed from delivering air volume toward the first blades 41 and the second blades 51. Under the action of the wind field of the supply fan blades 31, the first blades 41 and the second blades 51 follow the rotation, and at this time the first motor and the second motor are both in power generation mode. The first motor and the second motor are both connected to the energy storage battery, and can charge the energy storage battery. Combined with Figure 5 As shown, due to the passive rotation of the first blade 41 and the second blade 51, the first blade 41 and the second blade 51 can also generate wind at this time, and the wind generated by the passive rotation can be used for heat exchange of the evaporator.

[0115] When the air supply volume demand is medium, the single motor power generation state is turned on. The second gear 72 rotates clockwise, driving the second rack 71 to rotate counterclockwise to the tangent position between the first blade 41 and the second blade 51. At this time, the wind field of the air supply blade 31 no longer affects the second blade 51, and the wind fields between the first blade 41 and the second blade 51 do not interfere with each other. The wind field generated by the air supply blade 31 only drives the first blade 41 to rotate and generate electricity, and the second blade 51 rotates independently to supply air to the room.

[0116] When the air supply air volume demand is high, the first gear 62 rotates clockwise, driving the first rack 61 to rotate counterclockwise to the tangent position of the first blade 41 and the second blade 51. At this time, the second rack 71 is also located at the tangent position of the first blade 41 and the second blade 51. The wind fields of the first blade 41, the second blade 51 and the air supply fan blade 31 do not interfere with each other, and the first blade 41, the second blade 51 and the air supply fan blade 31 rotate independently to reach the highest air volume state.
