[0044] The air outlet device 100 of the air conditioner indoor unit 1000 according to the embodiments of the present application is described below with reference to the drawings.

[0045] Referring to Figures 1-14 As shown, the air outlet device 100 according to the embodiments of the present application is used in the air conditioner indoor unit 1000, and the air outlet device 100 can include an air outlet panel 10, an air deflector 20 and a driving assembly 30.

[0046] Specifically, the air outlet panel 10 has an air outlet 11, such as Figures 1-3 As shown, the airflow inside the indoor unit 1000 of the air conditioner flows outward through the air outlet 11. The air guide plate 20 is movably mounted on the air outlet panel 10 and is used to open and close the air outlet 11, for example... Figures 1-5 As shown, with the indoor unit 1000 of the air conditioner operating, the air deflector 20 is opened to open the air outlet 11 to allow air to flow; for example... Figure 6 As shown, when the indoor unit 1000 is in standby mode (i.e., when it stops working), the air guide plate 20 closes the air outlet 11 to protect the internal components of the indoor unit 1000.

[0047] The drive assembly 30 includes a drive motor 31 and a transmission mechanism 32. The drive motor 31 and the air guide plate 20 are connected by the transmission mechanism 32. The drive motor 31 drives the air guide plate 20 to move along a first direction between a first position and a second position. When the air guide plate 20 is in the second position, the drive motor 31 drives the air guide plate 20 to move along a second direction between a second position and a third position. The second direction is different from the first direction.

[0048] The drive motor 31 can be a stepper motor, AC motor or DC motor, etc., which can provide driving force to the transmission mechanism 32 to drive the air guide plate 20 to move.

[0049] The first and second directions can extend along a straight line to move the air guide plate 20, or they can extend along a curve to rotate the air guide plate 20, as long as the first and second directions are different. The difference between the first and second directions allows the air guide plate 20 to move to a variety of different positions, resulting in diverse air guiding forms.

[0050] like Figure 6 As shown, in the first position, the air guide plate 20 closes the air outlet 11, putting the indoor unit 1000 of the air conditioner into standby mode, which helps to prevent external dust and other contaminants from entering the air conditioner. Figure 7 As shown, in the second position, there is a preset distance between the air guide plate 20 and the air outlet 11, so that an air outlet gap is formed between the outer periphery of the air guide plate 20 and the air outlet panel 10, which communicates with the air outlet 11. This allows the airflow inside the indoor unit 1000 to flow outward through the air outlet gap, thus preventing direct blowing and improving user comfort. This preset distance can be designed according to actual needs, such as the required air outlet efficiency and the required volume of the air outlet device 100.

[0051] like Figure 8As shown, in the state of the third position, the air deflector 20 opens the air outlet 11 and is located at one side of the air outlet 11 to avoid the air outlet 11, so that the air outlet 11 is completely opened, the airflow in the air conditioner indoor unit 1000 can quickly flow to the outside, the air outlet speed is faster, the air outlet efficiency is higher, and the cooling efficiency or heating efficiency of the air conditioner indoor unit 1000 is higher. And the air deflector 20 can be extended as the air duct 310 in the air conditioner indoor unit 1000 to control the flow direction of the airflow, improve the air deflection effect of the air deflector 20.

[0052] The driving motor 31 can drive the air deflector 20 to move along the first direction from the first position to the second position, along the second direction from the second position to the third position to completely open the air outlet 11, and also can drive the air deflector 20 to move along the second direction from the third position to the second position, along the first direction from the second position to the first position to completely close the air outlet 11 through the transmission mechanism 32.

[0053] In some related technologies, the air deflector of the air conditioner indoor unit rotates to open or close the air outlet, so that the airflow in the air conditioner indoor unit flows to the outside in the state that the air deflector opens the air outlet. But the rotation center of the air deflector is located inside the air outlet, i.e. inside the air conditioner indoor unit, and space needs to be reserved between the outer periphery of the air deflector and the edge of the air outlet for the air deflector to move, so that the air deflector cannot completely close the air outlet in the state that the air deflector closes the air outlet, and foreign matters such as dust, mosquitoes and small stones from the outside are easy to enter the inside of the air conditioner indoor unit from the gap between the outer periphery of the air deflector and the edge of the air outlet, which damages the internal components of the air conditioner indoor unit and shortens the service life of the air conditioner indoor unit.

[0054] In the present application, the air deflector 20 is located outside the air outlet 11 during the movement between the first position and the second position and during the movement between the second position and the third position, so that the air deflector 20 moves outside the air outlet 11. Therefore, the outer periphery of the air deflector 20 and the edge of the air outlet 11 are not easy to interfere, and space needs to be reserved between the outer periphery of the air deflector and the edge of the air outlet for the air deflector 20 to move, so that the air deflector 20 in the first position can completely close the air outlet 11, so that foreign matters such as dust, mosquitoes and small stones from the outside are not easy to enter the inside of the air conditioner indoor unit 1000, which is beneficial to protect the internal components of the air conditioner indoor unit 1000 and prolong the service life of the air conditioner indoor unit 1000.

[0055] In addition, the air deflector 20 also has two air guiding states in the second position and the third position, which can make the air flow more from the air outlet gap between the outer periphery of the air deflector 20 and the air outlet panel 10 in the state that the air deflector 20 is in the second position, reduce the air flow directly blowing to the user located outside the air deflector 20, realize the direct blowing prevention effect, and improve the use comfort of the user. The air deflector 20 can also be completely opened in the state that the air deflector 20 is in the third position. The air outlet 11 realizes rapid air outlet, meets the demand of the user for rapid refrigeration or rapid heating, can provide multiple air outlet options for the user to meet different use demands of the user.

[0056] According to the air outlet device 100 of the air conditioner indoor unit 1000 in the embodiment of the present application, the air deflector 20 can be completely closed in the state that the air deflector 20 is in the first position to protect the internal components of the air conditioner indoor unit 1000, the air deflector 20 can also realize the direct blowing prevention effect in the state that the air deflector 20 is in the second position, and the air deflector 20 can also realize the rapid air outlet in the state that the air deflector 20 is in the third position, which is beneficial to meet different use demands of the user.

[0057] As shown in Figures 1-14 According to the air outlet device 100 of the air conditioner indoor unit 1000 in the embodiment of the present application, the air deflector 20 can be completely closed in the state that the air deflector 20 is in the first position to protect the internal components of the air conditioner indoor unit 1000, the air deflector 20 can also realize the direct blowing prevention effect in the state that the air deflector 20 is in the second position, and the air deflector 20 can also realize the rapid air outlet in the state that the air deflector 20 is in the third position, which is beneficial to meet different use demands of the user.

[0058] According to the air outlet device 100 of the air conditioner indoor unit 1000 in the embodiment of the present application, the air deflector 20 can be completely closed in the state that the air deflector 20 is in the first position to protect the internal components of the air conditioner indoor unit 1000, the air deflector 20 can also realize the direct blowing prevention effect in the state that the air deflector 20 is in the second position, and the air deflector 20 can also realize the rapid air outlet in the state that the air deflector 20 is in the third position, which is beneficial to meet different use demands of the user.

[0059] In some embodiments, as shown in Figure 2 The shell 200 includes a bottom plate 210, a face frame 220 and a panel 230, the face frame 220 is arranged on the bottom plate 210 and the face frame 220 has an air inlet on the upper side, and the panel 230 is arranged on the front side of the face frame 220. The air duct component 300 includes an air duct volute, and the air duct volute has an air duct volute tongue, an air duct upper diffuser section and an air duct lower diffuser section, and the air duct volute tongue, the air duct upper diffuser section and the air duct lower diffuser section define the air duct 310.

[0060] The air conditioner indoor unit 1000 further comprises a heat exchanger 410, a fan 420, a heater 430 and a swing leaf 440. The heat exchanger 410 can be an evaporator. The fan 420 can comprise a cross-flow fan wheel and a motor for driving the cross-flow fan wheel to rotate. The heater 430 is used for heating in the heating process to improve the heating effect of the air conditioner indoor unit 1000. The swing leaf 440 is arranged in the air duct 310 and can swing to guide the airflow flowing outward. During the working process of the air conditioner indoor unit 1000, the airflow flows to the outside through the air inlet, the heat exchanger 410, the fan 420, the air duct 310 and the air outlet 11.

[0061] In some embodiments of the present application, as shown in Figures 6-7 and Figures 9-10 The driving motor 31 is used for driving the air deflector 20 to move linearly along the first direction between the first position and the second position. The first direction is perpendicular to the surface on which the air outlet 11 is located, for example, the first direction is parallel to the F1 direction extending in a straight line as shown in Figures 6-7 The air outlet panel 10 can be an arc-shaped panel, a flat panel or other irregularly shaped panel. Correspondingly, the air outlet panel 10 of different shapes can define different shapes of the air outlet 11.

[0062] The air deflector 20 is moved linearly along the first direction away from the air outlet panel 10 to open the air outlet 11. The air deflector 20 is moved linearly along the first direction to the air outlet panel 10 to open the air outlet 11. The air deflector 20 is not easy to interfere with the edge of the air outlet 11. The air deflector 20 in the first position can completely close the air outlet 11 to completely shield the air outlet 11, which is beneficial to protect the internal components of the air conditioner indoor unit 1000.

[0063] In some embodiments, the edge of the air outlet 11 is provided with a step, and the air deflector 20 in the first position is arranged outside the step to completely close the air outlet 11, which is better for shielding the air outlet 11. In some embodiments, the edge of the air outlet 11 is provided with a groove, and the air deflector 20 is provided with a protrusion matched with the groove. The protrusion of the air deflector 20 in the first position is matched with the groove of the air outlet panel 10 to completely close the air outlet 11, which is better for shielding the air outlet 11.

[0064] In some embodiments, as shown in Figures 7-10 The driving motor 31 is used for driving the air deflector 20 to rotate along the second direction between the second position and the third position, that is, the second direction extends along a curve, for example, the second direction is Figures 7-8The air deflector 20 rotates from the second position to the third position to fully open the air outlet 11, which can reduce the movement space required by the air deflector 20 outside the air outlet 11, reduce the occupied space of the air outlet device 100, and facilitate making the structure of the air outlet device 100 more compact while being able to fully open the air outlet 11.

[0065] In some embodiments of the present application, as shown in Figures 9-12 As shown, the transmission mechanism 32 includes a driving transmission member 321 and a driven transmission member 322. The driving transmission member 321 is in transmission connection with the driving motor 31, and the driving motor 31 is arranged in one of the air outlet panel 10 and the air deflector 20. The driven transmission member 322 is arranged in the other one of the air outlet panel 10 and the air deflector 20, and the driven transmission member 322 is in transmission connection with the driving transmission member 321, so that the driving motor 31 drives the driving transmission member 321 to move to drive the driven transmission member 322 to move, and then drive the air deflector 20 to move.

[0066] The driven transmission member 322 includes a first transmission part 3221 and a second transmission part 3223. During movement of the air deflector 20 in the first direction between the first position and the second position, the first transmission part 3221 is in transmission connection with the driving transmission member 321. During movement of the air deflector 20 in the second direction between the second position and the third position, the second transmission part 3223 is in transmission connection with the driving transmission member 321.

[0067] Therefore, the driving transmission member 321 is always in transmission connection with the same driven transmission member 322 during movement of the air deflector 20 between the first position, the second position and the third position, the movement of the air deflector 20 between the three positions can be realized by at least one set of transmission mechanism 32, without the need for two sets of mechanisms to respectively realize the movement of the air deflector 20 between the first position and the second position, and the movement of the air deflector 20 between the second position and the third position, which facilitates reducing the number of required transmission mechanisms 32, simplifying the structure of the driving assembly 30, reducing the manufacturing cost of the air outlet device 100, reducing the installation space required by the air outlet device 100 inside the air conditioner indoor unit 1000, and making the overall volume of the air conditioner indoor unit 1000 smaller. The more transmission mechanisms 32 means the greater risk of failure, for example, the driving transmission member 321 and the driven transmission member 322 are in transmission cooperation by gear and rack set engagement, the more the number of gear and rack sets, the more likely to fail, such as tooth fracture, tooth surface wear, tooth surface plastic deformation, etc. The present application reduces the number of transmission mechanisms 32, which can reduce the risk of failure of the driving assembly 30, and make the movement of the air deflector 20 more reliable.

[0068] In some embodiments, as shown in Figures 10-12As shown, the driving member 321 comprises a gear 3211, the first driving part 3221 is a first rack 3222 extending in the first direction, and the second driving part 3223 is a second rack 3224 extending in the second direction. The driving motor 31 drives the air deflector 20 to move from the first position to the second position through the meshing transmission of the gear 3211 and the first rack 3222, and drives the air deflector 20 to move from the second position to the third position through the meshing transmission of the gear 3211 and the second rack 3224. The transmission precision of the gear and rack meshing transmission is high, and the meshing transmission of the gear 3211 and the rack (the first rack 3222 or the second rack 3224) can improve the movement precision of the air deflector 20, which is beneficial to accurately moving the air deflector 20 to the first position, the second position or the third position, so that the air deflector 20 can better achieve the effects of completely closing the air outlet 11 at the first position, preventing direct blowing at the second position, and quickly blowing at the third position.

[0069] In some embodiments, as shown in Figure 10 The first rack 3222 and the second rack 3224 are integrally formed, so that the first rack 3222 and the second rack 3224 are not easy to separate, and the connection between the first rack 3222 and the second rack 3224 is smoother, so that the gear 3211 can move from the first rack 3222 to the second rack 3224 or from the second rack 3224 to the first rack 3222 more smoothly, and the air deflector 20 is not easy to shake during movement, and the movement stability of the air deflector 20 is better.

[0070] In some embodiments, as shown in Figure 10 The first rack 3222 is a straight rack, and the second rack 3224 is an arc rack. The meshing transmission of the gear 3211 and the straight rack enables the air deflector 20 to move along a straight line between the first position and the second position, which can make the air deflector 20 more accurately move to the first position or the second position, and also facilitates the air deflector 20 in the first position to more completely close the air outlet 11. The meshing transmission of the gear 3211 and the arc rack enables the air deflector 20 to rotate along an arc between the second position and the third position, which can make the air deflector 20 more accurately move to the second position or the third position, and can also reduce the movement space required by the air deflector 20 outside the air outlet 11, so that the structure of the air deflector 100 is more compact.

[0071] In some embodiments in which the first driving part 3221 is the first rack 3222 and the second driving part 3223 is the second rack 3224, as shown in Figure 10As shown, the driven transmission member 322 is provided with a limiting groove 3226, which includes a first groove section 3227 and a second groove section 3228 in communication. The first groove section 3227 is in position correspondence with the first rack 3222 and extends in the first direction, and the second groove section 3228 is in position correspondence with the second rack 3224 and extends in the second direction. Among them, the gear 3211 is connected with the driving motor 31 through the connecting shaft 311, the connecting shaft 311 penetrates the limiting groove 3226 and moves along the extension direction of the limiting groove 3226, which can make the gear 3211 and the connecting shaft 311 rotate synchronously, and the driving force of the driving motor 31 can be transmitted to the gear 3211 through the connecting shaft 311 and then to the rack (the first rack 3222 or the second rack 3224), so as to drive the air deflector 20 to move.

[0072] The limiting groove 3226 can limit the connecting shaft 311, so that the connecting shaft 311 is not easy to come out of the limiting groove 3226, thereby limiting the gear 3211 connected with the connecting shaft 311. The first groove section 3227 limits the meshing of the gear 3211 and the first rack 3222, and the second groove section 3228 limits the meshing of the gear 3211 and the second rack 3224, so that the driving member 321 and the driven transmission member 322 are always in transmission cooperation during the movement of the air deflector 20 between the first position, the second position and the third position, that is, the gear 3211 meshes with the first rack 3222 or the second rack 3224, and the gear 3211 and the rack (the first rack 3222 or the second rack 3224) are not easy to separate, so that the process of driving the air deflector 20 to move by the driving motor 31 through the transmission mechanism 32 is more stable.

[0073] In some embodiments, as Figures 10-12 As shown, the driven transmission member 322 further includes a body portion 3225, and the limiting groove 3226 is provided through the thickness direction of the body portion 3225. Among them, the two sides of the thickness direction of the body portion 3225 are provided with the first transmission portion 3221 and the second transmission portion 3223, that is, the number of the first transmission portion 3221 is two, and the number of the second transmission portion 3223 is two. The number of the gear 3211 is two, the body portion 3225 is stopped between the two gears 3211, the two gears 3211 are connected through the connecting shaft 311, which can make the two gears 3211 and the connecting shaft 311 rotate synchronously, so as to transmit the driving force of the driving motor 31 to the two gears 3211 through the connecting shaft 311, and each gear 3211 can be in transmission connection with the corresponding first transmission portion 3221 and the second transmission portion 3223.

[0074] The two gears 3211 are respectively matched with the two racks (the first rack 3222 or the second rack 3224) on the two sides of the thickness direction of the body part 3225, the movement of the two gears 3211 can be constrained in the thickness direction of the body part 3225, the risk of the gears 3211 deviating from or even separating from the racks is reduced, the movement of the gears 3211 is more stable, and the movement stability of the air deflector 20 is improved.

The second transmission part 3223 is arranged farther away from the air deflector 20, so that the air deflector 20 moves between the second position and the third position by cooperation of the second transmission part 3223 farther away from the air deflector 20 and the driving transmission member 321, so that the air deflector 20 stays at a position farther away from the air outlet 11, and the distance between the air deflector 20 in the second position and the third position and the air outlet 11 is farther, and the air outlet speed is faster.

[0077] In some embodiments, in a state in which the air deflector 20 is in the third position, one side edge of the air outlet 11 abuts against the driven transmission member 322, for example, the first transmission part 3221 abuts against the edge of the air outlet 11, or the second transmission part 3223 abuts against the edge of the air outlet 11. In the state in which the air deflector 20 is in the third position, the air deflector 20 is on one side of the air outlet 11 to avoid the air outlet 11, and the side edge of the air outlet 11 abuts against the driven transmission member 322 in this state, so that the distance between the air deflector 20 in this state and the air outlet 11 is maximized, so that the air outlet 11 is opened to the maximum, the air deflector 20 reduces the obstruction to the air flow flowing outward, the air outlet speed at the air outlet 11 is faster, and the cooling or heating efficiency of the air conditioner indoor unit 1000 is higher.
