Description

Technical Field

[0001] This invention relates to the field of household appliances, and in particular to an air conditioner. Background Technology

[0002] Traditional floor-standing air conditioners typically use a single cross-flow fan or a single centrifugal fan to drive airflow, with only one air outlet. The airflow direction is changed by the movement of the blades, resulting in a limited airflow pattern. Furthermore, cross-flow fans have relatively low airflow and pressure, failing to provide sufficient air volume and unable to achieve long-distance radial air delivery. Centrifugal fans, with their fixed structure, struggle to achieve long-distance axial air delivery, and the resulting high-speed, strong winds blow directly onto the user, leading to a poor user experience.

[0084] Traditional floor-standing air conditioners typically use a single cross-flow fan or a single centrifugal fan to drive airflow, with only one air outlet. The airflow direction is changed by the movement of the blades, resulting in a limited airflow pattern. Furthermore, cross-flow fans have relatively low airflow and pressure, failing to provide sufficient air volume and unable to achieve long-distance radial air delivery. Centrifugal fans, with their fixed structure, struggle to achieve long-distance axial air delivery, and the resulting high-speed, strong winds blow directly onto the user, leading to a poor user experience.

[0085] Therefore, this invention provides an air conditioner 100 comprising a cross-flow impeller 101 and multiple centrifugal impellers 102 distributed on both sides of the cross-flow impeller 101 along its axial direction. The multiple centrifugal impellers 102 and the cross-flow impeller 101 can respectively deliver air outward. Under the combined action of the multiple centrifugal impellers 102 and the cross-flow impeller 101, the air conditioner 100 can combine the advantages of both. It utilizes the centrifugal impellers 102 to provide greater air volume and air pressure to the outside, and delivers air to a greater distance in the radial direction. It utilizes the low power and low noise characteristics of the cross-flow impeller 101 to reduce the noise and energy consumption of the air conditioner 100 and reduce the complexity of the structure of the air conditioner 100.

[0086] Furthermore, in this embodiment of the invention, the air conditioner 100 housing 1 is provided with a plurality of first air outlets 2 and a plurality of second air outlets 6. The plurality of first air outlets 2 are located on the upper and lower sides of the front surface 111 of the housing, and the plurality of second air outlets 6 are distributed on the left and right sides of the front surface 111 of the housing. By controlling whether the plurality of air outlets located in various directions emit air and the air outlet direction of each air outlet, the air conditioner 100 can form a variety of different air outlet modes, enriching the air outlet forms of the air conditioner 100, better realizing the various functions of the air conditioner 100, and giving users a better experience.

[0087] Furthermore, the centrifugal impeller 102 or the cross-flow impeller 101 is correspondingly arranged with one or more of the multiple air outlets to deliver air to the corresponding air outlet. Since the impeller can directly deliver air to the corresponding air outlet, the resistance of the airflow during the flow to the air outlet is reduced, ensuring strong airflow at the air outlet and ensuring the air delivery distance of the air conditioner 100.

[0088] The following is for reference. Figures 1-39 An air conditioner 100 according to an embodiment of the present invention is described.

[0089] like Figures 1-39 As shown in the figure, this application embodiment provides an air conditioner 100, which includes: a casing 1, a cross-flow fan 101 and a plurality of centrifugal fans 102.

[0090] In the vertical direction, multiple centrifugal impellers 102 are distributed on both sides of the axial direction of the cross-flow impeller 101. The multiple centrifugal impellers 102 and the cross-flow impeller 101 can respectively send air outward. Under the joint action of the multiple centrifugal impellers 102 and the cross-flow impeller 101, the air conditioner 100 can combine the advantages of both. It can use the centrifugal impeller 102 to provide greater air volume and air pressure to the outside, and send air to a greater distance in the radial direction. It can use the cross-flow impeller 101 to reduce the noise and energy consumption of the air conditioner 100 and reduce the complexity of the structure of the air conditioner 100.

[0091] Specifically, the air conditioner 100 includes a cross-flow fan 101, one or more first centrifugal fans 1021 disposed above the cross-flow fan 101, and one or more second centrifugal fans 1022 disposed below the cross-flow fan 101.

[0092] Furthermore, the housing 1 is provided with multiple first air outlets 2, which are located on the front surface 111 of the housing. Each centrifugal impeller 102 is correspondingly arranged with at least one first air outlet 2 to deliver air towards the first air outlet 2. Thus, the airflow generated from the outlet of the centrifugal impeller 102 can be directly blown out through the first air outlet 2, reducing wind resistance and ensuring the wind speed and airflow volume from the first air outlet 2, thereby ensuring the air outlet distance of the air conditioner 100.

[0093] The first air outlet 2 includes an upper air outlet 21 corresponding to the first centrifugal impeller 1021 and a lower air outlet 22 corresponding to the second centrifugal impeller 1022. The upper air outlet 21 and the lower air outlet 22 can send air out separately or simultaneously. In the cooling mode of the air conditioner, cold air has the characteristic of flowing downwards in the room. In order to ensure the uniformity of indoor temperature stratification, the air conditioner 100 can mainly send air out through the upper air outlet 21 so that the upper air in the room can also have cold air flow, thereby improving the cooling effect of the air conditioner 100. In the heating mode of the air conditioner, high-temperature airflow has the characteristic of flowing upwards in the room. In order to ensure the uniformity of indoor temperature stratification, the air conditioner 100 can mainly send air out through the lower air outlet 22 so that the lower temperature in the room can also be raised, thereby improving the heating effect of the air conditioner 100.

[0094] The upper air outlet 21 and the lower air outlet 22 can also simultaneously supply air outwards to meet the user's needs for airflow from all directions.

[0095] Therefore, by controlling whether and in what direction each first air outlet 2 emits air, a variety of different air outlet methods can be formed, enriching the air outlet forms of the air conditioner 100, better realizing the various functions of the air conditioner 100, and giving users a better experience.

[0096] The casing 1 is also provided with multiple second air outlets 6, which are distributed on the left and right sides of the front surface 111 of the casing. Thus, in addition to blowing air upward and downward, the air conditioner 100 can also blow air to the left and right, enriching the air outlet mode of the air conditioner 100 and better realizing the function of the air conditioner 100 in regulating room temperature.

[0097] The cross-flow fan 101's outlet side is simultaneously connected to multiple second air outlets 6 via split-flow ducts 9. The casing 1 defines multiple split-flow ducts 9, the inlets of which are simultaneously connected to the outlet side of the cross-flow fan 101, and the outlets of which form multiple second air outlets 6. Since the second air outlets 6 are located in the middle of the air conditioner 100, they are more likely to directly blow air onto the user. The middle of the air conditioner 100 provides a gentler breeze, better meeting user comfort requirements. The second air outlets 6 are supplied with air by the cross-flow fan 101, providing a gentler and more comfortable breeze, thus improving the user experience.

[0098] The upper air outlet 21 in the first air outlet 2 is formed on the upper front side of the air conditioner 100. The air supply direction is usually upward and oblique. The centrifugal fan 102 delivers air to the upper air outlet 21, which can provide stronger air force and increase the air supply distance of the upper air outlet 21. It can achieve the effect of cooling airflow close to the top, which solves the problem that the previous single cross-flow cabinet unit could not form airflow close to the top, and greatly improves the cooling comfort and uniformity.

[0099] The lower air outlet 22 in the first air outlet 2 is formed at the lower front side of the air conditioner 100. The air supply direction is usually downward and oblique. The centrifugal fan 102 supplies air to the lower air outlet 22, which can provide stronger air force and increase the air supply distance of the lower air outlet 22. It can achieve the effect of heating air supply close to the ground, which solves the problem that the previous single cross-flow cabinet unit could not form a close air supply, and greatly improves the heating comfort and uniformity.

[0100] According to the embodiment of this application, the air conditioner 100 is provided with a cross-flow fan 101 and centrifugal fan 102 on both the upper and lower sides of the cross-flow fan 101. Combining the advantages of the centrifugal fan 102 and the cross-flow fan 101, the centrifugal fan 102 provides greater air volume and air pressure upward or downward, so as to achieve the effect of heating close to the ground or cooling close to the ceiling. The cross-flow fan 101 has the characteristics of low power and low noise, thereby reducing the noise and energy consumption of the air conditioner 100 and improving user comfort.

[0101] Combination Figures 9-38 In the embodiment shown, the housing 1 is provided with a first air duct 3, and each first air outlet 2 and the corresponding centrifugal impeller 102 are connected through the first air duct 3. The housing is also provided with a connecting channel 8, and the first air ducts 3 spaced vertically are connected through the connecting channel 8.

[0102] When one of the first air outlets 2 corresponding to the first air ducts 3 at the upper and lower intervals is open while the other is closed, the independent setting of the first air ducts 3 will cause some of the airflow generated by the centrifugal impeller 102 to be unable to be discharged outside the air conditioner 100. The corresponding centrifugal impeller 102 can only be closed, resulting in insufficient air volume or air volume loss. By setting a connecting channel 8 between the upper air duct 31 and the lower air duct 32, the airflow in the first air duct 3 corresponding to the closed first air outlet 2 can be guided to the first air duct 3 corresponding to the open first air outlet 2, and then sent out of the air conditioner 100 through the open first air outlet 2, thus avoiding air volume loss.

[0103] The first air duct 3 includes an upper air duct 31 and a lower air duct 32 spaced apart vertically. The first centrifugal impeller 1021 located above the cross-flow impeller 101 is connected to its corresponding upper air outlet 21 through the upper air duct 31. The second centrifugal impeller 1022 located below the cross-flow impeller 101 is connected to its corresponding lower air outlet 22 through the lower air duct 32. The connecting channel 8 connects the upper air duct 31 and the lower air duct 32.

[0104] To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the cooling mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the upper air outlet 21. At this time, the lower air outlet 22 is closed, and the airflow in the lower air duct 32 is guided by the structure of the lower air outlet 22 to the connecting channel 8. The airflow flows to the upper air duct 31 through the connecting channel 8 and mixes with the airflow in the upper air duct 31. The mixed airflow continues to flow along the upper air duct 31 and is blown to the outside through the upper air outlet 21. Since the upper air outlet 21 is located at the top, the air conditioner 100 can blow cold air to the upper part of the room, so that the upper air in the room can also have cold air flow, thereby improving the cooling effect of the air conditioner 100 on the room.

[0105] To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the heating mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the lower air outlet 22. At this time, the upper air outlet 21 is closed, and the airflow in the upper air duct 31 is guided by the structure of the upper air outlet 21 to the connecting channel 8, and flows to the lower air duct 32 through the connecting channel 8, where it mixes with the airflow in the lower air duct 32. The mixed airflow continues to flow along the lower air duct 32 and is blown to the outside through the lower air outlet 22. Since the lower air outlet 22 is located at the bottom, the air conditioner 100 can blow warm air to the lower part of the room, so that the lower air in the room can also have warm air flow, thereby improving the heating effect of the air conditioner 100 on the room.

[0106] Reference Figure 7The upper and lower openings of the connecting channel 8 can be provided with perforated grilles 81 to cover the connecting channel 8, prevent dust and foreign objects in the external environment from entering the connecting channel 8 and causing blockage, and also ensure the aesthetics of the air conditioner 100.

[0107] like Figure 13 , Figure 18 , Figure 23 , Figure 28 , Figure 33 and Figure 38 As shown, at least one first air duct 3 is provided with a rotatable first air guide 4. The first air guide 4 is rotatable between a first state and a second state. In the first state, the first air guide 4 sends air towards the outside of the housing 1, and in the second state, the first air guide 4 sends air towards the connecting channel 8.

[0108] In other words, the first air guide 4 has at least two functions. The first function is to open or close the first air outlet 2. In the first state, the first air guide 4 directs air towards the outside of the casing 1, that is, the first air guide 4 can open the first air duct 3, thereby connecting the first air outlet 2 with the air outlet side of the corresponding centrifugal impeller 102. The airflow generated by the corresponding centrifugal impeller 102 can be directly blown out of the air conditioner 100 through the first air outlet 2. In the second state, the first air guide 4 directs air towards the connecting channel 8, that is, the first air guide 4 is closed between the first air duct 3 and the first air outlet 2. The first air outlet 2 cannot connect with the air outlet side of the corresponding centrifugal impeller 102 through the first air duct 3. Therefore, by switching the state of the first air guide 4 between the first state and the second state, the opening and closing of the corresponding first air outlet 2 can be controlled.

[0109] Another function is to guide the airflow in the first flow channel. In the first state, the first air guide 4 sends air out of the casing 1. At this time, the state of the first air guide 4 controls the air outlet direction of the corresponding first air outlet 2. In the second state, the first air guide 4 sends air out of the connecting channel 8. The first air guide 4 can guide the airflow in the first air duct 3 to the connecting channel 8. After being guided by the first air guide 4, the airflow can enter the connecting channel 8 more smoothly, reducing wind resistance and avoiding air volume loss.

[0110] Reference Figure 13 , Figure 18 , Figure 23 , Figure 28 , Figure 33 and Figure 38 Each first air duct 3 is provided with a first air guide 4. The first air guide 4 located at the top can be rotated to send air upwards to switch to the first state, and the first air guide 4 located at the bottom can be rotated to send air downwards to switch to the first state.

[0111] The first air duct 3 includes an upper air duct 31 and a lower air duct 32 spaced apart vertically. The first air guide 4 includes an upper air guide 41 and a lower air guide 42. The upper air guide 41 is located in the upper air duct 31, and the lower air guide 42 is located in the lower air duct 32. The first centrifugal impeller 1021 located above the cross-flow impeller 101 is connected to its corresponding upper air outlet 21 through the upper air duct 31 and is guided by the upper air guide 41 during its passage through the upper air duct 31. The second centrifugal impeller 1022 located below the cross-flow impeller 101 is connected to its corresponding lower air outlet 22 through the lower air duct 32 and is guided by the lower air guide 42 during its passage through the lower air duct 32.

[0112] To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the cooling mode of the air conditioner 100, such as Figure 2 and Figures 14-18 As shown, the air conditioner 100 can mainly deliver air outward through the upper air outlet 21. At this time, the lower air guide 42 switches to the second state, that is, the lower air guide 42 closes the lower air outlet 22 and guides the airflow in the lower air duct 32 to the connecting channel 8. The upper air guide 41 switches to the first state, that is, the upper air guide 41 rotates to deliver air upward.

[0113] The airflow in the lower air duct 32 is guided by the lower air guide 42 to the connecting channel 8, and flows to the upper air duct 31 through the connecting channel 8, where it mixes with the airflow in the upper air duct 31. The mixed airflow continues to flow along the upper air duct 31, and is guided by the upper air guide 41 as it passes through the upper air outlet 21, forming an upward oblique wind. As a result, the air conditioner 100 can blow the cold air to a higher position in the room. Since the centrifugal fan 102 can provide stronger airflow, it increases the air delivery distance of the upper air outlet 21, which can achieve the effect of cooling airflow close to the top, greatly improving the cooling comfort and uniformity.

[0114] The first air duct 3 includes an upper air duct 31 and a lower air duct 32 spaced apart vertically. The first air guide 4 includes an upper air guide 41 and a lower air guide 42. The upper air guide 41 is located in the upper air duct 31, and the lower air guide 42 is located in the lower air duct 32. The first centrifugal impeller 1021 located above the cross-flow impeller 101 is connected to its corresponding upper air outlet 21 through the upper air duct 31 and is guided by the upper air guide 41 during its passage through the upper air duct 31. The second centrifugal impeller 1022 located below the cross-flow impeller 101 is connected to its corresponding lower air outlet 22 through the lower air duct 32 and is guided by the lower air guide 42 during its passage through the lower air duct 32.

[0115] To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the heating mode of the air conditioner 100, such as Figure 3 and Figures 19-23 As shown, the air conditioner 100 can mainly deliver air outward through the lower air outlet 22. At this time, the upper air guide 41 switches to the second state, that is, the upper air guide 41 closes the upper air outlet 21 and guides the airflow in the upper air duct 31 to the connecting channel 8. The lower air guide 42 switches to the first state, that is, the lower air guide 42 rotates to deliver air downward.

[0116] The airflow in the upper air duct 31 is guided by the upper air guide 41 to the connecting channel 8, and flows down to the lower air duct 32 through the connecting channel 8, where it mixes with the airflow in the lower air duct 32. The mixed airflow continues to flow along the lower air duct 32, and is guided by the lower air guide 42 as it passes through the lower air outlet 22, forming a downward-sloping airflow. As a result, the air conditioner 100 can blow hot air to a lower part of the room. Since the centrifugal fan 102 can provide stronger airflow, it increases the air delivery distance of the lower air outlet 22, which can achieve the effect of heating and ground-level airflow, greatly improving the comfort and uniformity of cooling.

[0117] Furthermore, in both the first and second states, the first air guide 4 extends obliquely in the vertical direction. To make the appearance of the air conditioner 100 more aesthetically pleasing in the closed state, the first air guide 4 also includes a closed state, such as... Figure 1 and Figures 9-13 As shown, in the closed state, the first air guide 4 can be rotated to close the corresponding first air outlet 2. This ensures that the air conditioner 100 has a flat and aesthetically pleasing appearance when closed, while preventing dust and foreign objects from the external environment from entering the first air duct 3 or the connecting channel 8, thus affecting the service life of the air conditioner 100.

[0118] Furthermore, when the first air guide 4 rotates to the position of closing the corresponding first air outlet 2, the first air guide 4 extends in the vertical direction to make the appearance of the air conditioner 100 more flat and beautiful.

[0119] Reference Figures 1-38 The first air guide 4 is formed as a plate, the first rotation axis of the first air guide 4 extends horizontally, and the extension direction of the first rotation axis of the first air guide 4 is perpendicular to the flow direction of the airflow in the first air duct 3.

[0120] Specifically, the first air guide 4 includes an upper air guide 41 and a lower air guide 42. In the first state, the upper air guide 41, which is formed as a plate, rotates along the first rotation axis to a position where it extends upward in the airflow direction. In the second state, the upper air guide 41, which is formed as a plate, rotates along the first rotation axis to a position where it extends downward in the airflow direction, and the lower edge of the plate does not exceed the plane where the upper air outlet 21 is located in the airflow direction.

[0121] In the first state, the lower air guide 42, which is formed as a plate, rotates along the first rotation axis to a position where it extends downward in the airflow direction. In the second state, the lower air guide 42, which is formed as a plate, rotates along the first rotation axis to a position where it extends upward in the airflow direction, and the upper edge of the plate does not exceed the plane where the lower air outlet 22 is located in the airflow direction.

[0122] The angle between the first air guide 4 and the airflow direction in the first state is smaller than the angle between the first air guide 4 and the airflow direction in the second state.

[0123] like Figure 11 , Figure 16 , Figure 21 , Figure 26 , Figure 31 and Figure 36 As shown, a connecting channel 8 and a diversion channel 9 are formed in the space between the upper air duct 31 and the lower air duct 32 inside the casing 1. In the horizontal direction, the diversion channel 9 is distributed on the left and right sides of the connecting channel 8 to connect the air outlet side of the cross-flow fan 101 and the second air outlet 6 respectively located on the left and right sides, so that the air conditioner 100 has a compact structure and reasonable layout.

[0124] Reference Figure 7 , Figure 8 , Figure 30 , Figure 32 , Figure 35 and Figure 37 The housing 1 is provided with a first air duct 3. Each first air outlet 2 and the corresponding centrifugal impeller 102 are connected through the first air duct 3. The airflow formed on the air outlet side of the corresponding centrifugal impeller 102 needs to flow to the first air outlet 2 through the first air duct 3. Since the first air outlet 2 can only deliver air to the front of the air conditioner 100, it cannot meet the diverse air delivery needs of users. Therefore, at least one side wall of the first air duct 3 is provided with a side air outlet 7. Thus, the airflow formed on the air outlet side of the corresponding centrifugal impeller 102 can selectively flow to the first air outlet 2 or to the side air outlet 7 during the process of passing through the first air duct 3. The air conditioner 100 can deliver air to the front side through the first air outlet 2 or to both sides through the side air outlet 7, or simultaneously deliver air to the front side and both sides through the side air outlet 7 and the first air outlet 2, which enriches the air delivery mode of the air conditioner 100 and improves the user experience.

[0125] In some embodiments, such as Figure 7 and Figure 8 As shown, the housing 1 includes a first housing 11 forming the front surface of the housing 1. The first housing 11 also includes two side plates 112, and a side air outlet 7 is formed on the two side plates 112 of the first housing 11. The side air outlet 7 is located at the edge of the front surface 111 of the housing.

[0126] According to some embodiments of this application, each first air duct 3 is provided with side air outlets 7 on both the left and right sides, that is, the upper air duct 31 and the lower air duct 32 are provided with side air outlets 7 on both the left and right sides. Thus, the airflow in the upper air duct 31 can selectively flow forward and be blown out from the first air outlet 2 formed on the front surface of the housing 1, or be blown out through the side air outlets 7 formed on the left and right sides.

[0127] Reference Figure 7 , Figure 8 , Figure 30 , Figure 32 , Figure 35 and Figure 37 The side air outlet 7 is provided with a first switch door 71 for opening or closing. The first switch door 71 is located at the side air outlet 7 to control the opening and closing of the side air outlet 7. In different modes, the airflow in the first air duct 3 can be controlled by controlling the first switch door 71 and the first air guide 4. The air conditioner 100 can choose to vent air forward or to the side, or vent air forward and to the side at the same time.

[0128] Reference Figure 7 , Figure 8 , Figure 30 , Figure 32 , Figure 35 and Figure 37 Specifically, since the side air outlet 7 is formed as an opening that extends vertically in the length direction and horizontally in the width direction, and the length of the side air outlet 7 is much longer than the width of the side air outlet 7, the first switch door 71 is formed as a plate-like structure that extends vertically in the length direction and horizontally in the width direction, and the length is much longer than the width. The first switch door 71 is movably provided at the side air outlet 7 to open or close the side air outlet 7.

[0129] The first switch door 71 can move horizontally or rotate around the second rotation axis. Controlling the opening and closing of the side air outlet 7 by controlling the horizontal movement of the first switch door 71 involves a complex transmission mechanism, which will increase the production cost of the air conditioner 100. In order to simplify the structure of the first switch door 71 and reduce the production cost, the first switch door 71 controls the opening and closing of the side air outlet 7 by rotation.

[0130] In order to facilitate the arrangement of the motor used to drive the first door 71 to rotate and reduce the space occupied by the first door 71 during rotation, the second rotation axis of the first door 71 extends in the vertical direction. Thus, the motor used to drive the first door 71 to rotate can be located in the space above or below the first door 71 without affecting the volume of the air conditioner 100 in the front-to-back direction, and the internal space of the air conditioner 100 is utilized more rationally.

[0131] The second rotation axis can also be located on one side of the width direction of the first switch door 71. Furthermore, the second rotation axis can also be located at the center position of the width direction of the first switch door 71, so as to further reduce the space occupied by the first switch door 71 during rotation and make it easier to set up the motor.

[0132] According to some embodiments of this application, such as Figures 2-6 As shown, the left and right sides of the housing 1 are provided with a first notch 5 extending along the height direction. The first notch 5 is connected to the second air outlet 6 and the side air outlet 7. When the air conditioner 100 blows air to the left and right sides, the airflow must pass through the first notch 5.

[0133] In some embodiments, a portion of the first notch 5 forms a second air outlet 6.

[0134] like Figures 9-38 As shown, the first notch 5 is provided with a rotatable second air guide 51. The second air guide 51 is used to guide the air outlet direction of the second air outlet 6 and the side air outlet 7. The second air guide 51 is adapted to guide the air outlet direction of the second air outlet 6 and the side air outlet 7 to the left front or right front.

[0135] The second air guide 51 can also seal the first gap 5 when the air conditioner 100 is in the off state, preventing dust or foreign objects from the outside environment from entering the first gap 5 or the diversion air duct 9, and preventing foreign objects from the outside environment from invading the interior of the air conditioner 100 and affecting the service life of the air conditioner 100. When the second air guide 51 seals the first gap 5, the appearance of the air conditioner 100 is flat and beautiful, improving the aesthetics of the air conditioner 100 when it is not in operation.

[0136] Reference Figures 2-6 The air duct 9 is equipped with a swivel assembly 91, which includes multiple rotatable swivel blades 911 arranged in the vertical direction. Each swivel blade 911 can swing up and down to adjust the airflow direction. In different airflow modes, the swivel blades 911 can swing upwards or downwards to achieve better airflow. For example, in the cooling mode of the air conditioner 100, each swivel blade 911 of the swivel assembly 91 can swing upwards, controlling the airflow direction of the second air outlet 6 to be upwards, thereby further improving the cooling effect of the air conditioner 100 and improving the uniformity of indoor temperature. In the heating mode of the air conditioner 100, each swivel blade 911 of the swivel assembly 91 can swing downwards, controlling the airflow direction of the second air outlet 6 to be downwards, thereby further improving the heating effect of the air conditioner 100 and improving the uniformity of indoor temperature. In the strong wind mode where the user needs stronger airflow, the swivel blades 911 can rotate to a horizontal parallel position to achieve a direct airflow effect.

[0137] Reference Figure 11 , Figure 16 , Figure 21, Figure 26 , Figure 31 and Figure 36 The air outlet of the diversion duct 9 extends at an angle to the front and rear directions, so that the air outlet of the diversion duct 9 can blow air to the left front or right front.

[0138] like Figure 13 , Figure 18 , Figure 23 , Figure 28 , Figure 33 and Figure 38 As shown, the cross-flow fan 101 and multiple centrifugal fans 102 are coaxially arranged, wherein the cross-flow fan 101 has radial air intake and radial air outlet, and the centrifugal fans 102 have axial air intake and radial air outlet. The air outlet directions of the cross-flow fan 101 and multiple centrifugal fans 102 are the same, which facilitates the arrangement of the air conditioner 100.

[0139] Reference Figure 13 , Figure 18 , Figure 23 , Figure 28 , Figure 33 and Figure 38 The cross-flow fan 101 and multiple centrifugal fans 102 are driven by the same motor. That is, the multiple centrifugal fans 102 and the cross-flow fan 101 are located on the same rotating shaft. The motor can drive the cross-flow fan 101 and multiple centrifugal fans 102 simultaneously by driving the rotating shaft. This simplifies the structure of the air conditioner 100, avoids multiple motors occupying too much space inside the air conditioner 100, which would increase the size of the air conditioner 100, and can also reduce the production cost of the air conditioner 100.

[0140] In other embodiments, the multiple centrifugal impellers 102 and cross-flow impellers 101 can be driven by different motors to achieve more diverse airflow effects. For example, a motor can be provided above the multiple centrifugal impellers 102 and cross-flow impellers 101 to drive one or more centrifugal impellers 102 located above, and a motor can be provided below the multiple centrifugal impellers 102 and cross-flow impellers 101 to drive one or more centrifugal impellers 102 located below. The cross-flow impeller 101 can be driven by a separate motor or connected to the upper or lower motor shaft and driven by the same motor.

[0141] like Figure 39 As shown, each centrifugal impeller 102 is a dual-inlet centrifugal impeller 102, and the air inlet 1020 of the centrifugal impeller 102 is set vertically upward and downward.

[0142] Alternatively, the centrifugal impeller 102 may be a single-inlet centrifugal impeller 102. Specifically, the first centrifugal impeller 1021 is a single-inlet centrifugal impeller 102, with its air intake 1020 located above and vertically upward. The second centrifugal impeller 1022 is a single-inlet centrifugal impeller 102, with its air intake 1020 located below and vertically downward.

[0143] A specific embodiment of the air conditioner 100 is described below with reference to the accompanying drawings.

[0144] like Figures 1-39 As shown, the air conditioner 100 includes: a casing 1, a cross-flow fan 101, a first centrifugal fan 1021, and a second centrifugal fan 1022.

[0145] The cross-flow fan 101, the first centrifugal fan 1021, and the second centrifugal fan 1022 are coaxially arranged and the axial direction of the fan extends vertically. The cross-flow fan 101, the first centrifugal fan 1021, and the second centrifugal fan 1022 are driven by the same motor. The first centrifugal fan 1021 is located above the cross-flow fan 101, and the second centrifugal fan 1022 is located below the cross-flow fan 101.

[0146] The housing 1 is provided with an upper air outlet 21 corresponding to the first centrifugal impeller 1021 and a lower air outlet 22 corresponding to the second centrifugal impeller 1022. Both the upper air outlet 21 and the lower air outlet 22 are located on the front surface 111 of the housing. The air outlet side of the first centrifugal impeller 1021 is connected to the upper air outlet 21 through the upper air duct 31 defined by the housing 1, and the air outlet side of the second centrifugal impeller 1022 is connected to the lower air outlet 22 through the lower air duct 32 defined by the housing 1.

[0147] Side air outlets 7 are provided on both side walls of the upper air duct 31 and both side walls of the lower air duct 32. The housing 1 includes a first housing 11 forming the front surface of the housing 1. The first housing 11 also includes two side plates 112. The side air outlets 7 are opened on the two side plates 112 of the first housing 11. The side air outlets 7 are located at the edge of the front surface 111 of the housing. The side air outlets 7 are provided with a first switch door 71 for opening or closing. The first switch door 71 is rotatably disposed at the side air outlet 7 to control the opening and closing of the side air outlet 7. The rotation axis of the first switch door 71 extends vertically. The drive motors of the first switch doors 71 provided at the side air outlets 7 on both sides of the upper air duct 31 are located below the corresponding first switch doors 71, and the drive motors of the first switch doors 71 provided at the side air outlets 7 on both sides of the lower air duct 32 are located above the corresponding first switch doors 71. Each first switch door 71 is independently driven by its corresponding drive motor.

[0148] The first switch door 71 includes an open state and a closed state. In the closed state, the first switch door 71 rotates to a position parallel to the left and right side walls of the upper air duct 31 or the lower air duct 32. In the open state, the first switch door 71 rotates to a position inclined in the horizontal direction relative to the left and right side walls of the upper air duct 31 or the lower air duct 32.

[0149] The housing 1 is also provided with two second air outlets 6 on the left and right sides of the front surface of the housing 1, which correspond to the cross-flow fan 101. The air outlet side of the cross-flow fan 101 is connected to the second air outlets 6 through two diversion air ducts 9 defined by the housing 1.

[0150] The casing 1 has a first notch 5 extending along the height direction on both the left and right sides. A part of the first notch 5 forms a second air outlet 6, and the first notch 5 is also connected to the side air outlet 7. The first notch 5 is provided with a rotatable second air guide 51, which is used to guide the air outlet direction of the second air outlet 6 and the side air outlet 7.

[0151] The second air guide 51 has two states: an open state and a closed state. In the open state, the second air guide 51 rotates to the position where the first notch 5 is open; in the closed state, the second air guide 51 rotates to the position where the first notch 5 is closed. The rotation axis of the second air guide 51 also extends vertically. The two second air guides 51 are driven to rotate by two different drive motors.

[0152] The upper air duct 31 and the lower air duct 32 are arranged vertically at intervals. The housing 1 also defines a connecting channel 8, which connects the upper air duct 31 and the lower air duct 32. The upper and lower openings of the connecting channel 8 may be provided with perforated grilles 81 to cover the connecting channel 8, prevent dust and foreign objects from the external environment from entering the connecting channel 8 and causing blockage, and also ensure the aesthetics of the air conditioner 100.

[0153] A connecting channel 8 and a diversion channel 9 are formed in the space between the upper air duct 31 and the lower air duct 32 inside the casing 1. In the horizontal direction, the diversion channel 9 is distributed on the left and right sides of the connecting channel 8 to connect the air outlet side of the cross-flow fan 101 and the second air outlet 6 respectively located on the left and right sides, so that the air conditioner 100 has a compact structure and reasonable layout.

[0154] The diversion duct 9 is equipped with a swivel assembly 91, which includes multiple rotatable swivel blades 911 arranged in the height direction. Each swivel blade 911 can swing up and down to adjust the air outlet direction. In different air outlet modes, the swivel blades 911 can be selected to swing up or down to achieve better air outlet effect.

[0155] The upper air duct 31 is provided with a rotatable upper air guide 41. The upper air guide 41 is formed as a plate and can switch its own state by rotating. The axis of rotation extends horizontally and is perpendicular to the flow direction of the airflow in the upper air duct 31.

[0156] The upper air guide 41 includes at least a first state, a second state, and a third state. The upper air guide 41 can be rotated to send air upwards to switch to the first state, can be rotated to send air towards the connecting channel 8 to switch to the second state, and can be rotated to be parallel to the vertical direction to switch to the third state.

[0157] The downdraft duct 32 is provided with a rotatable downdraft guide 42. The downdraft guide 42 is formed as a plate and can switch its own state by rotating. The axis of rotation extends horizontally and is perpendicular to the flow direction of the airflow in the downdraft duct 32.

[0158] The lower air guide 42 includes at least a first state, a second state, and a third state. The lower air guide 42 can be rotated to send air downwards to switch to the first state, can be rotated to send air towards the connecting channel 8 to switch to the second state, and can be rotated to be parallel to the vertical direction to switch to the third state.

[0159] The air conditioner 100, when turned on, includes at least five modes, including:

[0160] like Figure 2 , Figures 14-18 In the first mode shown, when the air conditioner 100 is in the first mode, the upper air guide plate of the air conditioner 100 rotates to send air upwards to switch to the first state, the lower air guide plate of the air conditioner 100 rotates to send air towards the connecting channel 8 to switch to the second state, the second air guide 51 rotates to the position of opening the first notch 5 to switch to the open state, each blade 911 of the sway assembly 91 can swing upwards to control the air outlet 6 to send air upwards, and the first switch door 71 rotates to the position parallel to the left and right side walls of the upper air duct 31 or the lower air duct 32 to switch to the closed state.

[0161] The first mode is usually activated when the air conditioner 100 is cooling. In the cooling mode of the air conditioner 100, the air conditioner 100 mainly sends air out through the upper air outlet 21 and the second air outlet 6. At this time, the airflow in the lower air duct 32 driven by the second centrifugal impeller 1022 is guided by the lower air guide 42 to the connecting channel 8, and flows to the upper air duct 31 through the connecting channel 8, where it mixes with the airflow in the upper air duct 31. The mixed airflow continues to flow along the upper air duct 31. During the process of passing through the upper air duct 31, it is guided by the upper air guide 41 and blown to the outside through the upper air outlet 21, forming an upward oblique wind. As a result, the air conditioner 100 can blow the cold air to a higher place in the room. Since the centrifugal impeller 102 can provide stronger wind force, it increases the air delivery distance of the upper air outlet 21, which can achieve the effect of cooling airflow close to the top, greatly improving the cooling comfort and uniformity.

[0162] like Figure 3 , Figures 19-23 In the second mode shown, when the air conditioner 100 is in the second mode, the lower air guide plate of the air conditioner 100 rotates to send air downwards to switch to the first state, the upper air guide plate of the air conditioner 100 rotates to send air towards the connecting channel 8 to switch to the second state, the second air guide 51 rotates to the position of opening the first notch 5 to switch to the open state, each blade 911 of the sway assembly 91 can swing downwards to control the air outlet 6 to send air downwards, and the first switch door 71 rotates to the position parallel to the left and right side walls of the upper air duct 31 or the lower air duct 32 to switch to the closed state.

[0163] The second mode is usually activated when the air conditioner 100 is in heating mode. In the heating mode of the air conditioner 100, the air conditioner 100 mainly sends air out through the lower air outlet 22 and the second air outlet 6. At this time, the airflow in the upper air duct 31 driven by the first centrifugal impeller 1021 is guided by the upper air guide 41 to the connecting channel 8, and flows to the lower air duct 32 through the connecting channel 8, where it mixes with the airflow in the lower air duct 32. The mixed airflow continues to flow along the lower air duct 32. During the process of passing through the lower air duct 32, it is guided by the lower air guide 42 and blown to the outside through the lower air outlet 22, forming a downward oblique wind. As a result, the air conditioner 100 can blow hot air to a lower part of the room. Since the centrifugal impeller 102 can provide stronger wind force, it increases the air delivery distance of the lower air outlet 22, which can achieve the effect of heating and ground-level airflow, greatly improving the heating comfort and uniformity.

[0164] like Figure 4 , Figures 24-28In the third mode shown, when the air conditioner 100 is in the third mode, the upper air guide plate of the air conditioner 100 rotates to send air upwards to switch to the first state, the lower air guide plate of the air conditioner 100 rotates to send air downwards to switch to the first state, the second air guide 51 rotates to open the first notch 5 to switch to the open state, each blade 911 of the sway assembly 91 can swing to a position extending horizontally, controlling the air outlet 6 to send air horizontally, and the first switch door 71 rotates to a position parallel to the left and right side walls of the upper air duct 31 or the lower air duct 32 to switch to the closed state.

[0165] The third mode is usually activated when the air conditioner 100 needs to simultaneously supply air from the top and bottom for cooling or heating. In the mode where the air conditioner 100 supplies air from the top and bottom for cooling or heating, the air conditioner 100 simultaneously supplies air out through the upper air outlet 21, the lower air outlet 22, and the second air outlet 6. At this time, the airflow in the lower air duct 32 driven by the second centrifugal impeller 1022 is guided to the lower part of the room by the lower air guide 42, and the airflow in the upper air duct 31 driven by the first centrifugal impeller 1021 is guided to the upper part of the room by the upper air guide 41. Thus, the air conditioner 100 can blow cold or warm air to all parts of the room.

[0166] like Figure 5 , Figures 29-33 In the fourth mode shown, when the air conditioner 100 is in the fourth mode, the upper air guide plate of the air conditioner 100 rotates to send air upwards to switch to the first state, the lower air guide plate of the air conditioner 100 rotates to send air downwards to switch to the first state, the second air guide 51 rotates to the position of opening the first notch 5 to switch to the open state, each blade 911 of the sway assembly 91 can swing to the position of extending horizontally, controlling the air outlet 6 to send air horizontally, and the first switch door 71 rotates to the position of being inclined relative to the left and right side walls of the upper air duct 31 or the lower air duct 32 in the horizontal direction to switch to the open state.

[0167] The fourth mode is usually activated when the air conditioner 100 needs to provide airflow throughout the room. In the air conditioner 100's full-area airflow mode, the air conditioner 100 simultaneously sends air out through the upper air outlet 21, the lower air outlet 22, the side air outlet 7, and the second air outlet 6. At this time, part of the airflow in the lower air duct 32 driven by the second centrifugal impeller 1022 is blown out by the lower air outlet 22 and guided to the lower part of the room by the lower air guide 42, and part of it is blown out by the side air outlet 7 and guided to the left and right sides by the second air guide plate. Part of the airflow in the upper air duct 31 driven by the first centrifugal impeller 1021 is blown out by the upper air outlet 21 and guided to the upper part of the room by the upper air guide 41, and part of it is blown out by the side air outlet 7 and guided to the left and right sides by the second air guide plate. Thus, the air conditioner 100 can blow air to all parts of the room, and strong airflow can be generated in all directions.

[0168] like Figure 6 , Figures 34-38 In the fifth mode shown, when the air conditioner 100 is in the fifth mode, the upper air guide plate of the air conditioner 100 rotates to the second or third state of closing the upper air outlet 21, the lower air guide plate of the air conditioner 100 rotates to the second or third state of closing the lower air outlet 22, the second air guide 51 rotates to the position of opening the first notch 5 to switch to the open state, each blade 911 of the blade assembly 91 can swing to the position of extending in the horizontal direction, controlling the air outlet 6 to air out in the horizontal direction, and the first switch door 71 rotates to the position of being inclined in the horizontal direction relative to the left and right side walls of the upper air duct 31 or the lower air duct 32 to switch to the open state.

[0169] The fifth mode is usually activated when the air conditioner 100 needs to vent air from both sides. In the air conditioner 100 venting air from both sides mode, the air conditioner 100 simultaneously vents air outward through the side air outlet 7 and the second air outlet 6. At this time, the airflow in the lower air duct 32 driven by the second centrifugal impeller 1022 is blown out through the side air outlet 7 and guided to the left and right sides by the second air guide plate. The airflow in the upper air duct 31 driven by the first centrifugal impeller 1021 is blown out through the side air outlet 7 and guided to the left and right sides by the second air guide plate. Thus, the air conditioner 100 can blow air to the left and right sides of the room.

[0170] When the air conditioner is off (100%), such as Figure 1 , Figures 9-13 As shown, the upper air guide plate of the air conditioner 100 rotates to be parallel to the vertical direction to switch to the third state, the lower air guide plate of the air conditioner 100 rotates to be parallel to the vertical direction to switch to the third state, the second air guide 51 rotates to the position of closing the first notch 5 to switch to the closed state, and the first switch door 71 rotates to the position of being parallel to the left and right side walls of the upper air duct 31 or the lower air duct 32 to switch to the closed state.

[0171] Other configurations and operations of the air conditioner 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
