Description

Air conditioner indoor unit and air conditioner with it

[0001] This application claims priority to the patent application filed on December 25, 2024, with application number 202411929171.2 and titled "Air Conditioner Indoor Unit and Air Conditioner Having the Indoor Unit". Technical Field

[0002] This application relates to the field of air conditioning indoor unit technology, and more specifically, to an air conditioning indoor unit and an air conditioner having the same. Background Technology

[0003] Currently, existing indoor air conditioners use cross-flow fans to deliver air downwards. When the air conditioner is in heating mode, this downward airflow directs hot air towards the floor, resulting in better heating and greater comfort.

[0004] However, downward airflow can cause direct airflow during cooling, resulting in poor user comfort. Therefore, existing technology includes indoor air conditioners using dual cross-flow fans. These two fans achieve upward and downward airflow respectively, providing better comfort in both cooling and heating modes. However, these dual cross-flow air conditioners are larger and more expensive. Summary of the Invention

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] As shown in Figures 1 to 8, Embodiment 1 of this application provides an air conditioner indoor unit, which includes a housing 10, a cross-flow fan 20, and a duct housing 30. The housing 10 is provided with an upper air outlet 11 and a lower air outlet 12. The cross-flow fan 20 and the duct housing 30 are both disposed inside the housing 10; the duct housing 30 forms an air duct, and the cross-flow fan 20 is disposed inside the air duct. The duct housing 30 includes a first volute assembly 31 and a second volute assembly 32, which are spaced apart on both sides of the cross-flow impeller 20 to form a first air outlet 33 and a second air outlet 34 connected to the duct. The first air outlet 33 is located on the side of the second air outlet 34 near the upper air outlet 11. At least a portion of the first volute assembly 31 and at least a portion of the second volute assembly 32 are movably arranged so that the duct housing 30 can move to a first air supply position where the upper air outlet 11 discharges air and the lower air outlet 12 receives air, or a second air supply position where the upper air outlet 11 receives air and the lower air outlet 12 discharges air.

[0039] The air conditioner indoor unit provided in Embodiment 1 of this application can change the shape of the air duct by moving at least a portion of the first volute assembly 31 and at least a portion of the second volute assembly 32. This changes the position of the first or second volute assembly 31 to generate pressure on the airflow within the air duct, thereby adjusting the position of the eccentric vortex within the cross-flow impeller 20. This causes the eccentric vortex, originally located in the center of the cross-flow impeller 20, to move to the left or right, allowing airflow to enter from the lower air outlet 12 and exit from the upper air outlet 11, or vice versa. This reversible vertical airflow configuration improves the convenience of switching between upward and downward airflow states and ensures effective air delivery. Therefore, the air conditioner indoor unit provided in this embodiment solves the technical problem in the prior art where switching between upward and downward airflow states is inconvenient.

[0040] Specifically, along the height direction of the casing 10, the upper air vent 11 is located above the lower air vent 12.

[0041] It should be noted that "the first vent 33 is located on the side of the second vent 34 that is close to the upwind vent 11" can also be understood as the first vent 33 being located between the second vent 34 and the upwind vent 11.

[0042] Specifically, the indoor unit of the air conditioner also includes a first guide vane 13, which is movably mounted on the casing 10 and located at the upper air outlet 11. The indoor unit also includes a second guide vane 14, which is movably mounted on the casing 10 and located at the lower air outlet 12. This arrangement allows for adjustment of the air resistance at the upper air outlet 11 by using the first guide vane 13, and adjusts the air resistance at the lower air outlet 12 by using the second guide vane 14. This further guides the change in airflow direction when switching between upward and downward airflow states, thereby improving the switching effect between the two air supply states.

[0043] Specifically, the first guide vane 13 is rotatably disposed at the upper air outlet 11, with a rotation angle of m. The second guide vane 14 is rotatably disposed at the lower air outlet 12, with a rotation angle of n. When the duct housing 30 is in the first air supply position, m ≥ 10° and n ≥ 30°. With this arrangement, the air resistance at the upper air outlet 11 can be adjusted by adjusting the rotation angle of the first guide vane 13, and the air resistance at the lower air outlet 12 can be adjusted by adjusting the rotation angle of the second guide vane 14. This further guides the change in airflow direction when the air is expelled upwards, thereby improving the switching effect between the two air supply states.

[0044] Specifically, the first guide vane 13 is rotatably disposed at the upper air outlet 11, with a rotation angle of m. The second guide vane 14 is rotatably disposed at the lower air outlet 12, with a rotation angle of n. When the duct housing 30 is in the second air supply position, m ≥ 30° and n ≥ 10°. This arrangement allows for adjustment of the air resistance at the upper air outlet 11 by adjusting the rotation angle of the first guide vane 13, and of the air resistance at the lower air outlet 12 by adjusting the rotation angle of the second guide vane 14. This further guides the change in airflow direction during downward airflow, thereby improving the switching effect between the two air supply states.

[0045] Specifically, as shown in Figures 2 and 3, the first guide vane 13 has a first open position that avoids the upwind opening 11 and a first closed position that blocks the upwind opening 11, where m is the maximum rotation angle of the first guide vane 13 relative to its first closed position. Specifically, when the first guide vane 13 is in the first closed position, it is horizontal, and m is the rotation angle of the first guide vane 13 relative to the horizontal direction in a counterclockwise direction. The second guide vane 14 has a second open position that avoids the downwind opening 12 and a second closed position that blocks the downwind opening 12, where n is the maximum rotation angle of the second guide vane 14 relative to its second closed position. Specifically, when the second guide vane 14 is in the second closed position, it is horizontal, and n is the rotation angle of the second guide vane 14 relative to the horizontal direction in a clockwise direction.

[0046] Specifically, in order to facilitate the adjustment of airflow direction by rotating the first guide plate 13 and the second guide plate 14, one end of the first guide plate 13 is connected to the housing 10, and the other end of the first guide plate 13 is movably disposed. One end of the second guide plate 14 is connected to the housing 10, and the other end of the second guide plate 14 is movably disposed.

[0047] In this embodiment, the first volute assembly 31 includes a first volute 311 and a first rotating member 312, the first rotating member 312 being located on the side of the first volute 311 near the cross-flow impeller 20; the second volute assembly 32 includes a second volute 321 and a second rotating member 322, the second rotating member 322 being located on the side of the second volute 321 near the cross-flow impeller 20; the first rotating member 312 forms at least a portion of the first volute assembly 31; the second rotating member 322 forms at least a portion of the second volute assembly 32.

[0048] Specifically, when the duct housing 30 moves to the first air supply position, the first rotating member 312 rotates to generate pressure on the airflow in the duct, causing the eccentric vortex inside the cross-flow impeller 20 to move to the right, so that the airflow enters from the downwind port 12, flows through the cross-flow impeller 20 and flows out from the upwind port 11, forming an air supply mode of air outlet at the upwind port 11 and air inlet at the downwind port 12; when the duct housing 30 moves to the second air supply position, the second rotating member 322 rotates to generate pressure on the airflow in the duct, causing the eccentric vortex inside the cross-flow impeller 20 to move to the left, so that the airflow enters from the upwind port 11, flows through the cross-flow impeller 20 and flows out from the downwind port 12, forming an air supply mode of air inlet at the upwind port 11 and air outlet at the downwind port 12.

[0049] Specifically, when the duct housing 30 is in the first air supply position, 3° < α ≤ 30°; where α is the maximum included angle between the first rotating member 312 and the first volute 311. This structural arrangement better ensures the compression effect of the first rotating member 312 on the airflow by setting the included angle, thereby ensuring the movement of the eccentric vortex position and avoiding interference with the cross-flow impeller 20.

[0050] Specifically, when the duct housing 30 is in the second air supply position, 3° < β ≤ 30°; where β is the maximum included angle between the second rotating member 322 and the second volute 321. This structural arrangement better ensures the compression effect of the first rotating member 312 on the airflow by setting the included angle, thereby ensuring the movement of the eccentric vortex position and avoiding interference with the cross-flow impeller 20.

[0051] Specifically, the first rotating member 312 includes a first fixed part 3121 and a first rotating part 3122 connected to each other; the first fixed part 3121 is hinged to the first volute 311, and the first rotating part 3122 is rotatably disposed relative to the first fixed part 3121; the second rotating member 322 includes a second fixed part 3221 and a second rotating part 3222 connected to each other; the second fixed part 3221 is hinged to the second volute 321, and the second rotating part 3222 is rotatably disposed relative to the second fixed part 3221; the duct housing 30 also includes a connecting rod 35, one end of which is connected to the first rotating part 3122, and the other end of which is connected to the second rotating part 3222, so that the first rotating part 3122 drives the second rotating part 3222 to rotate through the connecting rod 35. With this structural arrangement, the first rotating member 312 and the second rotating member 322 can be coordinated through the linkage 35, which improves the convenience of switching the first rotating member 312 and the second rotating member 322 to switch the air supply state.

[0052] Specifically, the first rotating member 312 includes a first fixed portion 3121 and a first rotating portion 3122 connected to each other; the first fixed portion 3121 is hinged to the first volute 311, and the first rotating portion 3122 is rotatably disposed relative to the first fixed portion 3121; the second rotating member 322 includes a second fixed portion 3221 and a second rotating portion 3222 connected to each other; the second fixed portion 3221 is hinged to the second volute 321, and the second rotating portion 3222 is rotatably disposed relative to the second fixed portion 3221; the duct housing 30 also includes a driving member 36, the driving end of the driving member 36 being rotatably disposed and drivingly connected to the first rotating portion 3122. With this configuration, the first rotating member 312 can be driven to rotate by the driving member 36, improving the convenience of switching between the first rotating member 312 and the second rotating member 322 to switch the air supply state.

[0053] Specifically, the drive component 36 is a motor.

[0054] Specifically, as shown in Figure 2, the first rotating member 312 is an arc-shaped plate, and α is the angle between the tangent of the first rotating member 312 at the first fixed part 3121 and the tangent of the first volute 311 at the position corresponding to the first fixed part 3121.

[0055] Specifically, as shown in Figure 3, the second rotating member 322 is an arc-shaped plate, and β is the angle between the tangent of the second rotating member 322 at the second fixed part 3221 and the tangent of the second volute 321 at the position corresponding to the second fixed part 3221.

[0056] In this embodiment, the first rotating member 312 further includes a third rotating part 3125 connected to the first fixed part 3121. The first rotating part 3122 and the third rotating part 3125 are located on the upper and lower sides of the first fixed part 3121, respectively. When the air duct housing 30 is in the first air supply position, at least a portion of the third rotating part 3125 is in contact with the first volute 311, and at least a portion of the first rotating part 3122 is spaced apart from the first volute 311. When the air duct housing 30 is in the second air supply position, at least a portion of the third rotating part 3125 is spaced apart from the first volute 311, and at least a portion of the first rotating part 3122 is in contact with the first volute 311.

The fourth rotating part 3225 and the second rotating part 3222 are located on the upper and lower sides of the second fixed part 3221, respectively. When the air duct housing 30 is in the first air supply position, at least a portion of the fourth rotating part 3225 is spaced apart from the second volute 321, and at least a portion of the second rotating part 3222 is in contact with the second volute 321. When the air duct housing 30 is in the second air supply position, at least a portion of the fourth rotating part 3225 is in contact with the second volute 321, and at least a portion of the second rotating part 3222 is spaced apart from the second volute 321.

This arrangement, through the first positioning step 3111, avoids the third rotating part 3125 exerting excessive pressure on the airflow within the duct when the duct housing 30 is in the second air supply position, thus preventing it from affecting the gas flow direction. Simultaneously, it also helps to reduce dead zones and minimize airflow stagnation within the duct.

This arrangement, through the second positioning step 3211, avoids the fourth rotating part 3225 exerting excessive pressure on the airflow within the duct when the duct housing 30 is in the first air supply position, thus preventing it from affecting the gas flow direction. Simultaneously, it also helps to reduce dead zones and minimize airflow stagnation within the duct.

[0059] Specifically, "the end of the first positioning step 3111" refers to the protruding end of the first positioning step 3111. "The end of the second positioning step 3211" refers to the protruding end of the second positioning step 3211.

The heat exchanger 40 covers the first air outlet 33, and the flow divider 50 is movably disposed at the first air outlet 33. With this structural arrangement, the flow of gas can be guided to the direction of the heat exchanger 40 by the flow divider 50, so that the airflow can pass through the heat exchanger 40 more evenly and obtain sufficient heat exchange.

[0063] Specifically, to facilitate better heat exchange, the heat exchanger 40 includes a first heat exchange element 41 and a second heat exchange element 42 connected at a preset angle. The opening formed between the first heat exchange element 41 and the second heat exchange element 42 faces the first air outlet 33. Specifically, the heat exchanger 40 may include multiple heat exchange elements stacked on top of each other.

[0064] Specifically, in order to facilitate the guidance of gas flow, the flow divider 50 is a plate-shaped component.

[0065] Specifically, the indoor unit of the air conditioner also includes a filter element 61, which is disposed inside the housing 10 and is movably mounted. When the duct housing 30 is in the first air supply position, the filter element 61 covers the lower air outlet 12; when the duct housing 30 is in the second air supply position, the filter element 61 covers the upper air outlet 11. In this way, the movement of the filter element 61 can coordinate with the switching between the two air supply states, so that the airflow entering the duct can be filtered through the filter element 61 in either air supply state, reducing the entry of external dust and debris.

[0066] Specifically, the filter element 61 is an arc-shaped element. This arc-shaped filter element 61 reduces interference with other internal structures of the air conditioner indoor unit. Specifically, the filter element 61 is a filter screen.

[0067] Specifically, the indoor unit of the air conditioner also includes a drive gear 62 and a transmission rack 63, both of which are housed within the casing 10. The drive gear 62 and the transmission rack 63 are meshed together to drive the transmission rack 63 to move. The filter element 61 is mounted on the transmission rack 63. This structural arrangement allows the filter element 61 to move through the drive gear 62 and the transmission rack 63, improving the ease of switching the position of the filter element 61.

[0068] In this embodiment, in order to improve the convenience of switching the position of the filter element 61, the indoor unit of the air conditioner also includes a drive motor 64. The drive end of the drive motor 64 is connected to the drive gear 62 to drive the drive gear 62 to rotate.

[0071] Specifically, the indoor unit of the air conditioner also includes a second air-sweeping component 72, the sweeping part of which is movably disposed at the downwind outlet 12. With this structural arrangement, the airflow exiting from the downwind outlet 12 can be swept left and right by the second air supply component 72 when in the second air supply position.

[0072] In this embodiment, the indoor unit of the air conditioner also includes a filter element 61, which is movably disposed within the housing 10. The filter element 61 has a first filtering position and a second filtering position for respectively blocking the upper air vent 11 and the lower air vent 12. The indoor unit also includes a first air-sweeping element 71, which is movably disposed at the upper air vent 11. The first air-sweeping element 71 is configured to avoid the movement trajectory of the filter element 61 and is located outside the filter element 61. This structural arrangement avoids interference between the first air-sweeping element 71 and the movement of the filter element 61, thereby better ensuring the filtering function of the filter element 61.

[0073] Specifically, the first sweeping component 71 has a first sweeping range, and the first sweeping component 71 moves within the first sweeping range. The first sweeping range avoids the movement trajectory of the filter component 61 to prevent interference between their movements. Specifically, the movement trajectory of the filter component 61 can be an arc-shaped trajectory.

[0074] Specifically, in order to ensure the sweeping effect, the filter element 61 is an arc-shaped element, and the first sweeping element 71 is disposed between the outer arc edge of the arc-shaped element and the housing 10.

[0075] In this embodiment, the indoor unit of the air conditioner also includes a filter element 61, which is movably disposed within the housing 10. The filter element 61 has a first filtering position and a second filtering position for respectively blocking the upper air vent 11 and the lower air vent 12. The indoor unit also includes a second air-sweeping element 72, which is movably disposed at the lower air vent 12. The second air-sweeping element 72 is configured to avoid the movement trajectory of the filter element 61 and is located outside the filter element 61. This structural arrangement avoids interference between the second air-sweeping element 72 and the movement of the filter element 61, thereby better ensuring the filtering function of the filter element 61.

[0076] Specifically, the second sweeping member 72 has a second sweeping range, and the second sweeping member 72 moves within the second sweeping range. The second sweeping range avoids the movement trajectory of the filter member 61 to prevent interference between their movements. Specifically, the movement trajectory of the filter member 61 can be an arc-shaped trajectory.

[0077] Specifically, in order to ensure the sweeping effect, the filter element 61 is an arc-shaped element, and the second sweeping element 72 is disposed between the outer arc edge of the arc-shaped element and the housing 10.

[0078] Specifically, "outer side of filter element 61" refers to the side of filter element 61 away from the air duct. The first air-sweeping element 71 is located between filter element 61 and upper air outlet 11. The second air-sweeping element 72 is located between filter element 61 and lower air outlet 12.

[0079] Specifically, the indoor unit of the air conditioner also includes a drain pipe 80 for drainage, which is disposed inside the housing 10 and located on the side of the first volute assembly 31 away from the cross-flow fan 20.

[0080] It should be noted that the dashed lines in Figure 1 indicate the movable positions of the first rotating member 312, the second rotating member 322, and the filter member 61.

[0081] As shown in Figures 6 to 8, the indoor unit of the air conditioner has three modes: normal cooling, heating, and rapid cooling. In normal cooling mode, air is drawn in through the lower vent 12 and blown out through the upper vent 11. The airflow is guided by the first deflector 13, and the main airflow passes through the ceiling, gradually descending towards the end of the room, where it swirls and is drawn back into the indoor unit, forming an airflow circulation. In heating mode, air is drawn in through the upper vent 11 and blown out through the lower vent 12. The airflow is guided by the second deflector 14, and the main airflow passes through the floor, gradually rising slowly towards the end of the room, where it swirls and is drawn back into the indoor unit, forming an airflow circulation. In rapid cooling mode, air is drawn in through the upper vent 11 and blown out through the lower vent 12. Rotating the second deflector 14 at a predetermined angle directs the blown-out cold air to the area where people are active, achieving rapid cooling or a blowing effect.

[0082] In the second embodiment of this application, the first rotating member 312 includes a first fixed part 3121 and a first rotating part 3122 connected to each other; the first fixed part 3121 is hinged to the first volute 311, and the first rotating part 3122 is rotatably disposed relative to the first fixed part 3121; the second rotating member 322 includes a second fixed part 3221 and a second rotating part 3222 connected to each other; the second fixed part 3221 is hinged to the second volute 321, and the second rotating part 3222 is rotatably disposed relative to the second fixed part 3221; the air duct housing 30 also includes a connecting rod 35, one end of the connecting rod 35 is connected to the first rotating part 3122, and the other end of the connecting rod 35 is connected to the second rotating part 3222, so that the second rotating part 3222 drives the first rotating part 3122 to rotate through the connecting rod 35. With this structural arrangement, the first rotating member 312 and the second rotating member 322 can be coordinated through the linkage 35, which improves the convenience of switching the first rotating member 312 and the second rotating member 322 to switch the air supply state.

[0083] In Embodiment 2, the first rotating member 312 includes a first fixed portion 3121 and a first rotating portion 3122 connected to each other; the first fixed portion 3121 is hinged to the first volute 311, and the first rotating portion 3122 is rotatably disposed relative to the first fixed portion 3121; the second rotating member 322 includes a second fixed portion 3221 and a second rotating portion 3222 connected to each other; the second fixed portion 3221 is hinged to the second volute 321, and the second rotating portion 3222 is rotatably disposed relative to the second fixed portion 3221; the duct housing 30 also includes a driving member 36, the driving end of the driving member 36 being rotatably disposed and drivingly connected to the second rotating portion 3222. With this arrangement, the second rotating member 322 can be driven to rotate by the driving member 36, improving the convenience of switching between the first rotating member 312 and the second rotating member 322 to switch the air supply state.

[0084] In Embodiment 2, the first connecting part 3123, the second connecting part 3124, and the first fixing part 3121 are all positioning holes. The first rotating member 312 is hinged to the air duct housing 30 through the first fixing part 3121, and the first rotating member 312 is connected to the connecting rod 35 through the first connecting part 3123. Specifically, the third connecting part 3223, the fourth connecting part 3224, and the second fixing part 3221 are all positioning holes. The second rotating member 322 is hinged to the air duct housing 30 through the second fixing part 3221, and the second rotating member 322 is connected to the connecting rod 35 through the third connecting part 3223.

[0085] In Embodiment 3 of this application, the indoor unit of the air conditioner further includes a heat exchanger 40 and a flow divider 50, with the heat exchanger 40 disposed within the casing 10. The heat exchanger 40 covers the second air vent 34, and the flow divider 50 is movably disposed at the second air vent 34. This structural arrangement allows the flow divider 50 to guide the gas flow towards the heat exchanger 40, thereby enabling the airflow to pass through the heat exchanger 40 more evenly and achieve sufficient heat exchange.

[0086] In Embodiment 3, to facilitate better heat exchange, the heat exchanger 40 includes a first heat exchange element 41 and a second heat exchange element 42 connected at a preset angle. The opening formed between the first heat exchange element 41 and the second heat exchange element 42 faces the second air outlet 34.

[0087] Embodiment 4 of this application provides an air conditioner, which includes an indoor air conditioner unit provided in any one of Embodiments 1 to 3.

[0088] The air conditioner provided in Embodiment 4 of this application can change the shape of the air duct by moving at least a portion of the first volute assembly 31 and at least a portion of the second volute assembly 32. This changes the position of the first or second volute assembly 31, thereby pressurizing the airflow within the air duct and adjusting the position of the eccentric vortex within the cross-flow impeller 20. This causes the eccentric vortex, originally located in the center of the cross-flow impeller 20, to move to the left or right, allowing airflow to enter from the lower air outlet 12 and exit from the upper air outlet 11, or vice versa. This reversible vertical airflow configuration improves the convenience of switching the indoor unit between upward and downward airflow states, ensuring effective air delivery. Therefore, the air conditioner provided in this embodiment solves the technical problem in the prior art where the indoor unit of an air conditioner is inconvenient to switch between upward and downward airflow states.

[0089] As can be seen from the above description, the embodiments of this application achieve the following technical effects: They enable convenient switching between two air supply modes: top air intake and bottom air outlet, and bottom air intake and top air outlet. A rotating filter mechanism ensures effective air filtration for both air supply modes. This effectively achieves the reversible air outlet effect of a single cross-flow fan, enhances the convective heat exchange effect in the room, and improves the heat exchange capacity of the air conditioner.
