Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a reversible air supply component, an indoor unit, and an air conditioner. Background Technology

[0002] The conventional mainstream indoor air conditioner's duct structure consists of a single cross-flow fan, a single air inlet, a single air outlet, and a single or double row of folded evaporators. It delivers air for cooling and heating through air guides. This traditional air delivery method has problems such as a single air delivery form, hot air not reaching the ground, cold air easily blowing into people, concentrated airflow resulting in poor room uniformity, and insufficient air volume.

[0003] A reversible air-flow air conditioner is provided in the prior art, including a casing, an internal air duct, a heat exchanger, and a counter-rotating fan. The casing has an upper air inlet and a lower air inlet. The two ends of the internal air duct are connected to the upper air inlet and the lower air inlet, respectively. The heat exchanger and the counter-rotating fan are both disposed within the internal air duct, with the heat exchanger located below the upper air inlet and the counter-rotating fan located between the heat exchanger and the lower air inlet. During cooling, air is drawn in from the lower air inlet, passes through the counter-rotating fan, exchanges heat with the heat exchanger, and is finally blown out from the upper air inlet. During heating, air is drawn in from the upper air inlet, passes through the heat exchanger, exchanges heat with the counter-rotating fan, and is finally blown out from the upper air inlet, achieving a multi-directional airflow effect and creating a large air circulation in the room.

[0004] However, the internal air duct of the reversible air supply air conditioner provided in the prior art is a vertical through structure, and the air supply effect is not ideal as it relies solely on the counter-rotating fan for air supply. Utility Model Content

[0058] The following is combined with Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0059] This utility model provides a reversible air supply component, including:

[0060] The housing 100 has an upper air vent 110 and a lower air vent 120 formed thereon;

[0061] The air duct assembly 130 is rotatably disposed within the housing 100, and the air outlet of the air duct assembly 130 is respectively directed toward the upper air outlet 110 and the lower air outlet 120.

[0062] The air guiding structure includes a first air guiding component 140 and a second air guiding component 150. The first air guiding component 140 is disposed between the upper air outlet 110 and the air duct component 130, and the second air guiding component 150 is disposed between the lower air outlet 120 and the air duct component 130.

[0063] When the air outlet of the air duct assembly 130 faces the upper air outlet 110, the opening of the first air guide assembly 140 facing the air duct assembly 130 is adapted to the air outlet of the air duct assembly 130; the opening of the second air guide assembly 150 facing the lower air outlet 120 has the largest size.

The air duct component 130 is rotatably disposed inside the housing 100, and the air outlet of the air duct component 130 is respectively directed toward the upper air outlet 110 and the lower air outlet 120, thereby enabling air to be discharged from the top or bottom through the air duct component 130, thus achieving reversible air supply.

[0066] Secondly, the air guiding structure includes a first air guiding component 140 and a second air guiding component 150. The first air guiding component 140 is disposed between the upper air outlet 110 and the air duct component 130, and the second air guiding component 150 is disposed between the lower air outlet 120 and the air duct component 130. When the air outlet of the air duct component 130 faces the upper air outlet 110, that is, when the air is discharged from the top, the opening of the first air guiding component 140 facing the air duct component 130 is adapted to the air outlet of the air duct component 130. The opening size of the second air guiding component 150 facing the lower air outlet 120 is the largest, thereby maximizing the air intake of the reversible air supply component and ensuring that all the air volume of the air outlet of the air duct component 130 can be discharged through the first air guiding component 140, avoiding air volume loss and improving the air outlet effect.

[0073] When the rotating air duct 160 is in the lower air intake position, the air inlet faces the lower air outlet 120 and the air outlet faces the upper air outlet 110.

[0074] In some embodiments of the present invention described above, the air duct assembly 130 includes a rotating air duct 160 and an air duct drive assembly; the air duct drive assembly is used to drive the rotating air duct 160 and the centrifugal fan assembly 170 to rotate between an upper air inlet position and a lower air inlet position. When the rotating air duct 160 is in the upper air inlet position, the air inlet faces the upper air outlet 110 and the air outlet faces the lower air outlet 120.

[0078] In some embodiments of this utility model, the first air guide assembly 140 includes a first air duct plate 190, a first drive motor, a second air duct plate 200, and a second drive motor.

At this time, the second air duct plate 200 and the first air duct plate 190 are respectively located on both sides of the air outlet, and the free end of the second air duct plate 200 is inclined towards the upper air outlet 110.

[0083] In some embodiments of the present invention described above, the first air duct plate 190 and the second air duct plate 200 are rotatably disposed between the upper air outlet 110 and the air duct assembly 130. When the air is discharged from the top, the first air duct plate 190 and the second air duct plate 200 are located on both sides of the air outlet, which can guide all the air discharged from the air duct assembly 130 to the upper air outlet 110. When the air is discharged from the bottom, the gap between the first air duct plate 190 and the second air duct plate 200 is at its maximum, which can ensure that all the air entering from the upper air outlet 110 can flow to the air duct assembly 130, ensuring the maximum air intake.

The second upper drive motor is connected to the second upper hinge shaft 340 for driving the second upper air guide plate 320 to move between the second upper closed position and the second upper open position.

[0099] When the first upper air guide plate 310 is in the first upper closed position and the second upper air guide plate 320 is in the second upper closed position, the first upper air guide plate 310 and the second upper air guide plate 320 close the upper air outlet 110.

[0100] In some of the embodiments of the present invention described above, the upper air guide plate assembly 290 includes a first upper air guide plate 310, a first upper drive motor, a second upper air guide plate 320, and a second upper drive motor. The first upper air guide plate 310 and the second upper air guide plate 320 can close or open the upper air outlet 110 to achieve air guidance or dust prevention.

[0101] In some embodiments of this utility model, the lower air guide plate assembly 300 includes a first lower air guide plate 350, a first lower drive motor, a second lower air guide plate 360, and a second lower drive motor, wherein the first lower air guide plate 350 and the second lower air guide plate 360 ​​are respectively disposed on both sides of the lower air outlet 120;

[0102] The first lower air guide plate 350 is rotatably mounted on the lower air outlet 120 via the first lower hinge shaft 370. The first lower drive motor is connected to the first lower hinge shaft 370 for driving the first lower air guide plate 350 to move between the first lower closed position and the first lower open position.

[0103] The second lower air guide plate 360 ​​is rotatably mounted on the lower air outlet 120 via the second lower hinge shaft 380. The second lower drive motor is connected to the second lower hinge shaft 380 for driving the second lower air guide plate 360 ​​to move between the second lower closed position and the second lower open position.

[0104] When the first lower air guide plate 350 is in the first lower closed position and the second lower air guide plate 360 ​​is in the second lower closed position, the first lower air guide plate 350 and the second lower air guide plate 360 ​​close the lower air outlet 120.

[0106] In some embodiments of this utility model, the evaporator assembly 390 is disposed between the downdraft 120 and the duct assembly 130.

[0107] This utility model also provides an indoor unit, including the reversible air supply component as described above.

[0108] This utility model also provides an air conditioner, including the indoor unit as described above.

[0109] When the air conditioner provided by this utility model is in use and the cooling or heating mode is switched, the rotary drive motor is connected to the rotary disk 180 to drive the rotary disk 180 to rotate, so that the air outlet of the rotary air duct 160 faces the upper air outlet 110 or the lower air outlet 120.

[0110] It should be noted that, in order to prevent interference when the rotating air duct 160 rotates, the first air duct plate 190, the second air duct plate 200, the third air duct plate 230 and the fourth air duct plate 240 can be set to give way. After the rotating air duct 160 has rotated to its position, the first air duct plate 190, the second air duct plate 200, the third air duct plate 230 and the fourth air duct plate 240 are driven to the designated position.

[0111] In some practical usage scenarios, when the user turns on the air conditioner and sets it to cooling mode, using top airflow, the first upper air guide plate 310 opens to a 45-degree angle upwards, while the second upper air guide plate 320 remains stationary. The first and second lower air guide plates 350 and 360 both rotate to a vertical position. The first air duct plate 190 overlaps the air outlet of the air duct assembly 130, the second air duct plate 200 is positioned at a 45-degree angle upwards, and the third and fourth air duct plates 230 and 240 move to their maximum position towards the opening of the lower air outlet 120. The cross-flow fan assembly rotates clockwise, drawing indoor air in from the lower air outlet 120. The air then passes through the evaporator and sequentially through the second air guide assembly 150, the rotating air duct 160, and the first air guide assembly 140 before being blown out from the upper air outlet 110, achieving a shower-like cooling airflow. The first upper air guide plate 310 can be oscillating or stationary.

[0112] When the user turns on the air conditioner and sets it to heating mode, it uses bottom air outlet. The first upper air guide plate 310 and the second upper air guide plate 320 are opened to a vertical position, and the first lower air guide plate 350 and the second lower air guide plate 360 ​​are both rotated to a vertical position. The first air duct plate 190 and the second air duct plate 200 are moved to their maximum position towards the opening of the upper air outlet 110. The fourth air duct plate 240 overlaps the air outlet of the air duct assembly 130, and the third air duct plate 230 is set to be tilted downward at 45 degrees. The cross-flow fan assembly rotates clockwise, drawing indoor air in from the upper air outlet 110, passing through the rotating air duct 160 and the evaporator, and then blowing it out from the lower air outlet 120, achieving carpet-like heating and air distribution. The first lower air guide plate 350 and the second lower air guide plate 360 ​​can swing and guide air at the same direction and speed, or they can be stationary.

[0113] When the user switches from cooling mode to heating mode or vice versa, the first air duct plate 190 or the fourth air duct plate 240 is driven to rotate to make room, so as to avoid interference when the rotating air duct 160 rotates.
