[0049] The air conditioner indoor unit 1000 of the embodiment of the present invention is described below with reference to the drawings of the specification. The air conditioner indoor unit 1000 is assembled with the outdoor unit to form an air conditioner for adjusting the indoor ambient temperature. The air conditioner can be a split wall-mounted air conditioner, and the air conditioner can be a single cooling machine or a cooling and heating machine. In the description of the present invention, the air conditioner is taken as an example of a cooling and heating machine, and the air conditioner indoor unit 1000 of the present application has a windless mode, a direct blowing prevention mode, a direct blowing sweeping mode, a heating mode, a heating sweeping mode, a cooling mode, and a cooling sweeping mode.

[0050] like Figure 1 As shown, an air conditioner indoor unit 1000 according to an embodiment of the present invention includes: a housing 100 , a first air guide assembly 200 and a second air guide assembly 300 .

[0051] Among them, combined Figure 1 and Figure 2As shown, the housing 100 is provided with an air outlet 110. The air outlet 110 is used to achieve communication between the inside and outside of the housing 100, so that the air in the housing 100 can be discharged through the air outlet 110 to achieve the purpose of supplying air to the room, thereby adjusting the indoor temperature.

[0052] In some embodiments, an air outlet duct is formed in the housing 100, and the air outlet 110 communicates with the air outlet duct. In this way, the air in the air outlet duct can be discharged through the air outlet 110 to achieve the purpose of supplying air to the room.

[0053] In addition, other components of the air-conditioning indoor unit 1000 (for example, a heat exchanger, a fan, an electrical control box, etc.) are also installed in the outer shell 100. On the one hand, the outer shell 100 can support and protect the internal components. On the other hand, it can also have a certain decorative effect to enhance the aesthetics of the air-conditioning indoor unit 1000.

[0054] In some embodiments, the housing 100 includes a chassis, a face frame and a front panel 120. The face frame is arranged on the chassis, the front side of the face frame is open, the front panel 120 is arranged on the front side of the face frame, and an air outlet 110 is defined between the lower end of the front panel 120 and the face frame, thereby forming the housing 100.

[0055] Combination Figure 1-Figure 9 As shown, both the first wind guide component 200 and the second wind guide component 300 can be rotatably arranged at the air outlet 110, and the first wind guide component 200 is provided with a first wind dispersing area 210 for dispersing wind, and the second wind guide component 300 is provided with a second wind dispersing area 310 for dispersing wind. In other words, both the first wind guide component 200 and the second wind guide component 300 have wind dispersing areas for dispersing wind, wherein the first wind dispersing area 210 on the first wind guide component 200 is used to disperse the air flowing through it, so as to ensure the wind dispersing effect of the first wind guide component 200, and the second wind dispersing area 310 on the second wind guide component 300 is used to disperse the air flowing through it, so as to ensure the wind dispersing effect of the second wind guide component 300, thereby improving the wind dispersing effect of the air conditioner indoor unit 1000, reducing the wind speed, achieving a windless effect, avoiding the air discharged through the air outlet 110 from blowing directly on the user, and improving the comfort of the air conditioner indoor unit 1000, that is, improving the user experience.

[0056] Through the above-mentioned arrangement, when the first air guide component 200 and the second air guide component 300 are used to block the air outlet 110, the wind dispersion area can be used to weaken the speed of the air discharged through the air outlet 110, thereby comprehensively improving the windless air volume and temperature, greatly improving the wind comfort, and thus ensuring the comfort of the air conditioner indoor unit 1000.

[0057] In addition, the first air guide assembly 200 and the second air guide assembly 300 are both rotatably arranged at the air outlet 110 to facilitate adjusting the positions of the first air guide assembly 200 and the second air guide assembly 300 relative to the air outlet 110, so that the air conditioner indoor unit 1000 has multiple air outlet modes.

[0058] In some embodiments, in order to achieve the rotational connection of the first air guide component 200, a first rotating arm (not shown in the figure) can be set on the outer shell 100 near the air outlet 110, and one end of the first rotating arm is rotatably connected to the outer shell 100, and the other end of the first rotating arm is fixedly connected to the first air guide component 200. In this way, the first rotating arm can be used to drive the first air guide component 200 to rotate, so as to achieve the first air guide component 200 being rotatably set at the air outlet 110, thereby reducing the difficulty of laying out the first air guide component 200 and simplifying the structure of the air-conditioning indoor unit 1000.

[0059] Accordingly, in order to realize the rotational connection of the second air guide component 300, a second rotating arm (not shown in the figure) can be arranged on the outer shell 100 near the air outlet 110, and one end of the second rotating arm is rotationally connected to the outer shell 100, and the other end of the second rotating arm is fixedly connected to the second air guide component 300. In this way, the second rotating arm can be used to drive the second air guide component 300 to rotate, so as to realize the rotatable setting of the second air guide component 300 at the air outlet 110, thereby reducing the difficulty of laying out the second air guide component 300 and further simplifying the structure of the air-conditioning indoor unit 1000.

[0060] Combination Figure 2 and Figure 4 As shown, the air-conditioning indoor unit 1000 includes a windless mode and an anti-direct blowing mode. In the windless mode, the first air guide component 200 is located at a first position to send the air dispersed by the first wind dispersion area 210 downward, and the lower end of the second air guide component 300 overlaps with the front end of the first air guide component 200, and the upper end of the second air guide component 300 cooperates with the inner wall of the air outlet 110; in the anti-direct blowing mode, the first air guide component 200 is located at a first position, and an air supply channel for sending air forward is defined between the second air guide component 300 and the first air guide component 200. That is to say, whether in the windless mode or the anti-direct blowing mode, the first air guide component 200 is located in the first position to send the air dispersed by the first wind dispersion area 210 downward. In this way, while achieving a windless feeling in the air-conditioning indoor unit 1000, it can also prevent the hot air or cold air exported through the air outlet 110 from directly blowing on the user and enable the air-conditioning indoor unit 1000 to send air downward, thereby expanding the air outlet range of the air-conditioning indoor unit 1000.

[0061] At the same time, in the windless mode, the lower end of the second air guide component 300 is set to overlap with the front end of the first air guide component 200. In this way, when the air-conditioning indoor unit 1000 switches between the windless mode and the anti-direct blowing mode, the position of the second air guide component 300 can be directly adjusted without adjusting the position of the first air guide component 200, so as to reduce the difficulty of position adjustment of the second air guide component 300 and improve the convenience of position adjustment. At the same time, it can also avoid the air outlet direction and air outlet volume from changing drastically when the air-conditioning indoor unit 1000 switches between the windless mode and the anti-direct blowing mode, thereby ensuring the air outlet effect.

[0062] That is to say, under the premise that the first air guide component 200 is accurately positioned, the present application only needs to adjust the position of the second air guide component 300 to switch the air conditioner indoor unit 1000 between the windless mode and the anti-direct blowing mode.

[0063] In a specific embodiment, when the first air guide component 200 is located at the first position, the position of the second air guide component 300 is adjusted to adapt to the position of the second air guide component 300. When the lower end of the second air guide component 300 overlaps with the front end of the first air guide component 200 and the upper end of the second air guide component 300 cooperates with the inner wall of the air outlet 110 (such as Figure 2 As shown), the air conditioner indoor unit 1000 is in the windless mode; when the second air guide component 300 is adjusted to define an air supply channel for forward air supply between the second air guide component 300 and the first air guide component 200 (as shown Figure 4 As shown), the air-conditioning indoor unit 1000 is in the anti-direct blowing mode; when the second air guide component 300 switches between the above two positions, the air-conditioning indoor unit 1000 switches between the no-wind mode and the anti-direct blowing mode, and the air-conditioning indoor unit 1000 is in the anti-direct blowing purge mode.

[0064] In summary, when the air-conditioning indoor unit 1000 switches between the windless mode and the anti-direct blowing mode, the position of the first air guide component 200 remains unchanged, thereby avoiding drastic changes in the air outlet direction and air outlet volume of the air-conditioning indoor unit 1000, thereby ensuring the air outlet effect.

[0065] In addition, in the windless mode, the first air guide component 200 is set to supply air downward and the lower end of the second air guide component 300 is set to overlap with the front end of the first air guide component 200, and the second air guide component 300 can be used to supply air forward. That is to say, in the windless mode, the first air guide component 200 and the second air guide component 300 can cooperate to supply air downward and forward at the same time, expand the air supply range, and increase the air output, thereby improving the air outlet effect of the air-conditioning indoor unit 1000.

[0066] It can be seen from the above structure that the air-conditioning indoor unit 1000 of the embodiment of the present invention is provided with the first wind dispersion area 210 and the second wind dispersion area 310 to ensure the wind dispersion effect of the air-conditioning indoor unit 1000, and reduce the wind speed and wind volume to achieve the effect of no wind feeling, while avoiding the air discharged through the air outlet 110 directly blowing on the user, thereby improving the comfort of the air-conditioning indoor unit 1000, that is, improving the user experience.

[0067] In the windless mode, the lower end of the second air guide component 300 is arranged to overlap with the front end of the first air guide component 200. While ensuring a larger air output volume and a larger air output range, it can also reduce the difficulty of switching between the windless mode and the anti-direct blowing mode, and at the same time avoid large changes in the air output direction and air output volume of the air-conditioning indoor unit 1000 during the mode switching process, thereby ensuring the air output effect and further improving the comfort of the air-conditioning indoor unit 1000.

[0068] At the same time, the above-mentioned setting can also enable the air-conditioning indoor unit 1000 to have an anti-direct blowing and sweeping wind mode, that is, the first air guide component 200 is located at a first position and fixed, and the second air guide component 300 rotates in a circle relative to the first air guide component 200. In this way, there will be no strong wind feeling in the room, and rapid cooling or heating of the room can be achieved, thereby improving the user experience.

[0069] It can be understood that compared with the prior art, the air-conditioning indoor unit 1000 of the present application can not only ensure the windless effect, but also make it convenient for the air-conditioning indoor unit 1000 to switch between the windless mode and the anti-direct blowing mode, while ensuring that during the switching process, the air outlet direction and air outlet volume of the air-conditioning indoor unit 1000 will not change significantly, so as to improve the comfort of the air-conditioning indoor unit 1000.

[0070] It should be noted that the upper end of the second wind guide component 300 mentioned above can be understood as, in the windless mode, the end of the second wind guide component 300 close to the outer shell 100, and accordingly, the lower end of the second wind guide component 300 can be understood as, in the windless mode, the end of the second wind guide component 300 away from the outer shell 100; the front end of the first wind guide component 200 mentioned above can be understood as, in the windless mode, the end of the first wind guide component 200 away from the outer shell 100, and accordingly, the rear end of the first wind guide component 200 can be understood as, in the windless mode, the end of the second wind guide component 300 close to the outer shell 100.

[0071] It should also be noted that when it is necessary to operate the anti-direct blowing mode or the anti-direct blowing purge mode of the air-conditioning indoor unit 1000, the positions of the first air guide component 200 and the second air guide component 300 can be first adjusted to the state of operating the air-conditioning indoor unit 1000 in the windless mode, and then the second air guide component 300 can be controlled to rotate to realize the anti-direct blowing mode or the anti-direct blowing purge mode of the air-conditioning indoor unit 1000, and reduce the control difficulty of the anti-direct blowing mode or the anti-direct blowing purge mode.

[0072] In some embodiments, in the windless mode, the angle between the connecting line of the front and rear ends of the first air guide assembly 200 and the horizontal direction is in the range of 0° to 30°, and the horizontal direction extends along the front-to-back direction. This ensures that in the windless mode, the first air guide assembly 200 can deliver air downward, so that while achieving windless feeling of the air conditioner indoor unit 1000, it can also prevent the hot air or cold air derived from the air outlet 110 from blowing directly on the user and enable the air conditioner indoor unit 1000 to deliver air downward, thereby expanding the air outlet range of the air conditioner indoor unit 1000.

[0073] In a specific embodiment, in the windless mode, the angle between the line connecting the front and rear ends of the first air guide component 200 and the horizontal direction is 13°, that is, when the first air guide component 200 is in the first position, the angle between the line connecting the front and rear ends of the first air guide component 200 and the horizontal direction is 13°, thereby realizing the downward air supply by utilizing the first air guide component 200.

[0074] That is to say, the first air guide component 200 of the present application has a first position relative to the air outlet 110. In the first position, the angle between the line connecting the front and rear ends of the first air guide component 200 and the horizontal direction is 13°.

[0075] Optionally, the second air guide assembly 300 has a second position and a third position relative to the air outlet 110. In the second position, the lower end of the second air guide assembly 300 can overlap with the front end of the first air guide assembly 200 located at the first position (wherein, Figure 2 That is, a schematic diagram showing that the first air guide assembly 200 is in the first position and the second air guide assembly 300 is in the second position); when in the third position, an air supply channel for supplying air forward is defined between the second air guide assembly 300 and the first air guide assembly 200, and the connecting line between the upper and lower ends of the second air guide assembly 300 is parallel to the air supply direction of the air supply channel (wherein, Figure 4 That is, it is a schematic diagram showing that the first air guide assembly 200 is in the first position and the second air guide assembly 300 is in the third position).

[0076] It should be noted that the second air guide assembly 300 can be cyclically switched between the second position and the third position so that the air conditioner indoor unit 1000 operates in the anti-direct blowing purge mode (such as Figure 5 shown).

[0077] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, in the windless mode, the lower end of the second wind guide assembly 300 is located at the front side of the front end of the first wind guide assembly 200. It is convenient to achieve the overlapped cooperation between the lower end of the second wind guide assembly 300 and the front end of the first wind guide assembly 200, thereby ensuring that the cooperation between the first wind guide assembly 200 and the second wind guide assembly 300 can achieve the windless effect, and at the same time, it can also prevent the first wind guide assembly 200 from hindering the rotation of the second wind guide assembly 300, so that when the position of the first wind guide assembly 200 remains unchanged, the second wind guide assembly 300 can effectively rotate between the second position and the third position.

[0078] Specifically, in the windless mode, when the lower end of the second air guide component 300 is located on the front side of the front end of the first air guide component 200, the first air guide component 200 and the second air guide component 300 cooperate to achieve the closed air outlet 110. At this time, the air in the outer shell 100 is discharged through the first wind dispersion area 210 and the second wind dispersion area 310 respectively, so as to achieve the purpose of wind dispersion, thereby achieving the windless effect. At the same time, the first air guide component 200 and the second air guide component 300 cooperate to expand the air outlet range; when the anti-direct blowing mode needs to be operated, because the lower end of the second air guide component 300 is located on the front side of the front end of the first air guide component 200, at this time, it is only necessary to rotate the second air guide component 300 counterclockwise to switch the air conditioner indoor unit 1000 from the windless mode to the anti-direct blowing mode, so that the mode switching is simple and the air outlet volume changes little during the mode switching process.

[0079] In some embodiments, in the windless mode, the lower end of the second air guide component 300 is located at the front side of the front end of the first air guide component 200. The lower end of the second air guide component 300 can be stopped at the front side of the front end of the first air guide component 200, or the lower end of the second air guide component 300 can be spaced at the front side of the front end of the first air guide component 200, that is, the lower end of the second air guide component 300 is spaced from the front end of the first air guide component 200. In this way, while ensuring the windless air outlet effect, it is also convenient to switch between modes.

[0080] When the lower end of the second air guide assembly 300 is spaced apart from the front end of the first air guide assembly 200 , the spacing H is ≤ 5 mm, so as to avoid affecting the air outlet effect in the windless mode due to a large spacing.

[0081] In some embodiments of the present invention, Figure 4As shown, in the anti-direct blowing mode, the second air guide assembly 300 rotates to a avoidance position to avoid the front part of the air outlet 110. That is to say, the second air guide assembly 300 has a avoidance position to avoid the front part of the air outlet 110. When the air conditioner indoor unit 1000 operates in the anti-direct blowing mode, the second air guide assembly 300 rotates to the avoidance position to define an air supply channel for supplying air forward between the second air guide assembly 300 and the first air guide assembly 200. At this time, part of the air in the housing 100 can be discharged from the air supply channel to adjust the indoor air conditioning, while preventing the discharged air from blowing directly on the user, thereby improving the user experience.

[0082] Among them, the avoidance position mentioned here can also be understood as the third position mentioned above, that is, when the air-conditioning indoor unit 1000 operates in the anti-direct blowing mode, the second air guide component 300 is rotated so that the connecting line of the upper and lower ends of the second air guide component 300 is parallel to the air supply direction of the air supply channel. In this way, while defining an air supply channel for supplying air forward between the second air guide component 300 and the first air guide component 200, it can also reduce the obstruction of the second air guide component 300 to the air flow, so as to ensure the air output volume and air output speed, thereby ensuring the air outlet effect of the air-conditioning indoor unit 1000 in the anti-direct blowing mode.

[0083] In summary, in the anti-direct blowing mode, the first air guide component 200 is located in the first position, so that the angle between the line connecting the front and rear ends of the first air guide component 200 and the horizontal direction is 13°, so that it is convenient to use the first air guide component 200 to supply air downward, and the second air guide component 300 is located in the third position to define an air supply channel for supplying air forward between the second air guide component 300 and the first air guide component 200, and make the line connecting the upper and lower ends of the second air guide component 300 parallel to the air supply direction of the air supply channel, so as to realize the use of the air supply channel to supply air forward, while ensuring the air output, it can also prevent the air from blowing directly on the user.

[0084] Alternatively, if Figure 4 As shown, in the direct blowing prevention mode, the front end of the second air guide assembly 300 extends out of the front panel 120 of the housing 100. That is, the housing 100 has the front panel 120, and the front end of the second air guide assembly 300 extends out of the front panel 120, which can prevent the return air, that is, prevent the indoor air from flowing into the housing 100 through the air outlet 110, thereby ensuring the air outlet quality of the air conditioner indoor unit 1000, thereby ensuring the air outlet effect.

[0085] In a specific embodiment, because the front end of the second air guide component 300 extends out of the front panel 120, when part of the air flows downward along the front panel 120, the air can flow to the extended second air guide component 300. At this time, the second air guide component 300 is used to hinder the air from flowing into the outer shell 100 and guide the air to flow along its extension direction, thereby preventing the air from flowing directly into the outer shell 100 and achieving the purpose of preventing backflow.

[0086] Alternatively, if Figure 4 As shown, in the anti-direct blowing mode, the lower surface of the second air guide component 300 is formed into an arc-shaped surface convex upward. On the one hand, it is prevented that the lower surface of the second air guide component 300 blocks the air from flowing along the air supply channel, that is, the air outlet effect of the air conditioner indoor unit 1000 in the anti-direct blowing mode is guaranteed; on the other hand, the upper surface of the second air guide component 300 can be formed into an arc-shaped surface convex upward, so that the second air guide component 300 can be used to block the air from flowing into the housing 100, and further achieve the purpose of preventing backflow.

[0087] In some embodiments of the present invention, when the air conditioner indoor unit 1000 is in shutdown mode, the first air guide assembly 200 and the second air guide assembly 300 cooperate to shield the air outlet 110. This prevents foreign matter, dust, etc. in the room from entering the housing 100 through the air outlet 110, which improves the cleanliness of the housing 100 on the one hand, and prevents foreign matter from damaging the components in the housing 100 on the other hand, thereby extending the service life of the air conditioner indoor unit 1000. At the same time, shielding the air outlet 110 can also prevent users from visually observing the structural components in the housing 100, thereby improving the aesthetics of the air conditioner indoor unit 1000.

[0088] In some embodiments, when the air conditioner indoor unit 1000 is in the shutdown mode, the first air guide assembly 200 and the second air guide assembly 300 may be matched in the following manner: Figure 2 That is to say, when the air conditioner indoor unit 1000 is in the shutdown mode and the windless mode, the matching form of the first air guide component 200 and the second air guide component 300 is consistent to reduce the difficulty of adjusting the position of the first air guide component 200 and the second air guide component 300.

[0089] Alternatively, if Figure 2 and Figure 3 As shown, when the air conditioner indoor unit 1000 is in the off mode, the first pivot shaft 220 of the first air guide assembly 200 is located at the front of the first air guide assembly 200. While ensuring that the first air guide assembly 200 can rotate relative to the air outlet 110, the rear end of the rotated first air guide assembly 200 can be spaced apart from the housing 100, so that the first air guide assembly 200 has a avoidance position to avoid the bottom part of the air outlet 110 from discharging air, that is, to ensure that the air outlet 110 can directly send air downwards, thereby ensuring the quality of the air outlet.

[0090] It should be noted that, through the above settings, especially when the air conditioner indoor unit 1000 is running in heating mode, the air outlet 110 can be used to supply air downward to ensure the air volume, thereby achieving rapid indoor heating and improving user experience.

[0091] In a specific embodiment, when the heating mode of the air conditioner indoor unit 1000 is operated, the first air guide assembly 200 rotates counterclockwise around the first pivot shaft 220 at the first position to form an air supply duct for supplying air downward between the first air guide assembly 200 and the housing 100 .

[0092] Alternatively, if Figure 2 and Figure 3 As shown, in the shutdown mode, the second pivot shaft 320 of the second air guide assembly 300 is located at the upper part of the second air guide assembly 300. This allows the second air guide assembly 300 to be rotatably arranged at the air outlet 110. At the same time, the second pivot shaft 320 of the second air guide assembly 300 is arranged to be located at the upper part of the second air guide assembly 300, which can also ensure that when the air conditioner indoor unit 1000 is in the anti-direct blowing mode, the second air guide assembly 300 can rotate counterclockwise relative to the first air guide assembly 200, thereby defining an air supply channel for supplying air forward between the second air guide assembly 300 and the first air guide assembly 200, thereby ensuring the air output of the air conditioner indoor unit 1000 in the anti-direct blowing mode.

[0093] In some embodiments of the present invention, Figure 6 As shown, the air conditioner indoor unit 1000 includes a heating mode, in which the first air guide assembly 200 and the second air guide assembly 300 cooperate to shield the front part of the air outlet 110 and avoid the bottom part of the air outlet 110 to send air downward. That is to say, in the heating mode of the air conditioner indoor unit 1000, the first air guide assembly 200 and the second air guide assembly 300 are rotated to cooperate to shield the front part of the air outlet 110, and at the same time, the bottom part of the air outlet 110 can send air downward, so as to achieve the purpose of sending air downward in the room, and at the same time ensure the air volume, so as to achieve rapid indoor temperature rise and ensure the comfort of the air conditioner indoor unit 1000.

[0094] It should be noted that in the heating mode, the first air guide component 200 and the second air guide component 300 are used together to block the front part of the air outlet 110. At this time, part of the structure of the first air guide component 200 and the second air guide component 300 overlaps to prevent a large amount of air from being discharged from the first wind dispersion area 210 and the second wind dispersion area 310, thereby achieving the purpose of compressed air, thereby increasing the air outlet at the bottom of the air outlet 110 and ensuring the heating effect.

[0095] Alternatively, if Figure 6As shown, in the heating mode, the second air guide assembly 300 is located in front of the first air guide assembly 200 and the lower end of the first air guide assembly 200 extends out of the housing 100. The second air guide assembly 300 is arranged to be located in front of the first air guide assembly 200, so that the relative positions of the first air guide assembly 200 and the second air guide assembly 300 can be adjusted, so that in the heating mode, the first air guide assembly 200 and the second air guide assembly 300 can cooperate to cover the front part of the air outlet 110 to achieve the purpose of compressing the air; the lower end of the first air guide assembly 200 is arranged to extend out of the housing 100, so that the first air guide assembly 200 can be used to guide the wind guided out of the bottom part of the air outlet 110, so that the air can be blown to the indoor floor, so that the indoor temperature rises quickly, thereby ensuring the heating effect of the air conditioner indoor unit 1000.

[0096] Alternatively, if Figure 6 As shown, the first air guide assembly 200 has a fourth position, and the second air guide assembly 300 has a fifth position. When the first air guide assembly 200 is in the fourth position, the angle between the line connecting the front and rear ends of the first air guide assembly 200 and the vertical direction is in the range of 0° to 15°. When the second air guide assembly 300 is in the fifth position, the angle between the line connecting the upper and lower ends of the second air guide assembly 300 and the vertical direction is in the range of 0° to 15°, and the vertical direction extends in the up-down direction. In this way, when the first air guide assembly 200 is in the fourth position and the second air guide assembly 300 is in the fifth position, it can be ensured that the first air guide assembly 200 and the second air guide assembly 300 cooperate to cover the front part of the air outlet 110 and avoid the bottom part of the air outlet 110 to deliver air downward.

[0097] At the same time, by setting the first air guide component 200 in the fourth position so that the angle between the line connecting the front and rear ends of the first air guide component 200 and the vertical direction is in the range of 0° to 15°, while ensuring that the bottom part of the air outlet 110 can supply air downward, the extension direction of the first air guide component 200 can be parallel to the air outlet direction of the air outlet 110, thereby reducing the obstruction of the first air guide component 200 to the air flow, so as to ensure the air outlet volume and air outlet speed, and further ensure the air outlet effect of the air conditioner indoor unit 1000 in the heating mode.

[0098] In a specific embodiment, when the air conditioner indoor unit 1000 is switched from the shutdown mode to the heating mode, the first air guide component 200 can be first driven to rotate counterclockwise to switch the first air guide component 200 from the first position to the fourth position, and then the second air guide component 300 can be driven to rotate clockwise to switch the second air guide component 300 from the second position to the fifth position. The matching relationship between the first air guide component 200 and the second air guide component 300 after switching can be seen in Figure 6 .

[0099] Alternatively, if Figure 7As shown, the air-conditioning indoor unit 1000 includes a heating sweeping mode. In the heating sweeping mode, the first air guide component 200 reciprocates and avoids the bottom part of the air outlet 110 to supply air downward. The second air guide component 300 is located on the front side of the first air guide component 200 and is spaced to define an air guide channel for supplying air downward. The second air guide component 300 reciprocates. That is to say, in the heating and sweeping mode of the air-conditioning indoor unit 1000, the first air guide assembly 200 and the second air guide assembly 300 both rotate back and forth, and during the reciprocating rotation of the first air guide assembly 200 and the second air guide assembly 300, the first air guide assembly 200 always avoids the bottom part of the air outlet 110 to supply air downward, and the second air guide assembly 300 is always located at the front side of the first air guide assembly 200 and the second air guide assembly 300 can be spaced apart from the first air guide assembly 200 to define an air guide channel for supplying air downward, so that the bottom part of the air outlet 110 and the air guide channel can be used to discharge air toward the indoor floor at the same time, thereby further realizing rapid indoor temperature rise, thereby ensuring the heating effect of the air-conditioning indoor unit 1000.

[0100] In addition, because the first air guide assembly 200 and the second air guide assembly 300 both rotate back and forth in the heating sweeping mode of the air-conditioning indoor unit 1000, the linkage sweeping of the first air guide assembly 200 and the second air guide assembly 300 can be achieved, thereby achieving a large range of air stirring, thereby increasing the sweeping effect and achieving rapid indoor heating.

[0101] Optionally, when the air outlet 110 discharges air forward, the first air guide assembly 200 further has a sixth position parallel to the air outlet direction (the schematic diagram of the first air guide assembly 200 in the sixth position can be seen in FIG. Figure 8 ), when the air conditioner indoor unit 1000 operates in the heating and sweeping mode, the first air guide assembly 200 reciprocates between the fourth position and the sixth position, and the second air guide assembly 300 reciprocates between the fifth position and the third position.

[0102] In the description of the present invention, features limited to "first", "second", "third", "fourth", "fifth" and "sixth" may explicitly or implicitly include one or more of the features, which are used to distinguish and describe the features, without any order or importance.

[0103] Optionally, in the heating and sweeping mode of the air conditioner indoor unit 1000, the first air guide assembly 200 and the second air guide assembly 300 rotate synchronously. That is, when the first air guide assembly 200 rotates from the fourth position to the sixth position, the second air guide assembly 300 rotates from the fifth position to the third position synchronously, so as to define an air guide channel for sending air downward between the second air guide assembly 300 and the first air guide assembly 200, thereby ensuring the air outlet effect.

[0104] It should be noted that when it is necessary to operate the heating and sweeping mode of the air-conditioning indoor unit 1000, the positions of the first air guide component 200 and the second air guide component 300 can be first adjusted to the state when the air-conditioning indoor unit 1000 is operated in the heating mode, and then the first air guide component 200 and the second air guide component 300 can be controlled to rotate in the same direction at the same time to realize the heating and sweeping mode of the air-conditioning indoor unit 1000 and reduce the control difficulty of the heating and sweeping mode.

[0105] In some embodiments of the present invention, Figure 8 As shown, the air conditioner indoor unit 1000 includes a cooling mode, in which the first air guide assembly 200 avoids the bottom portion of the air outlet 110 and an air supply passage for supplying air forward is defined between the second air guide assembly 300 and the first air guide assembly 200. That is, in the cooling mode of the air conditioner indoor unit 1000, the first air guide assembly 200 and the second air guide assembly 300 are rotated so that an air supply passage for supplying air forward can be formed between the second air guide assembly 300 and the first air guide assembly 200, and the bottom portion of the air outlet 110 can supply air downward, so as to simultaneously supply air to the front and downward of the room, thereby ensuring the air volume, thereby achieving rapid cooling of the room and ensuring the comfort of the air conditioner indoor unit 1000.

[0106] In a specific embodiment, when the air-conditioning indoor unit 1000 is switched from the shutdown mode to the cooling mode, the first air-guiding component 200 can be driven to rotate counterclockwise first, so that the first air-guiding component 200 is switched from the first position to the sixth position, so that the connection line between the front and rear ends of the first air-guiding component 200 can be parallel to the air outlet direction, reducing the obstruction of the first air-guiding component 200 to the air flow, so as to ensure the air outlet volume and air outlet speed, and further ensure the air outlet effect of the air-conditioning indoor unit 1000 in the cooling mode, and then the second air-guiding component 300 is driven to rotate counterclockwise, so that the second air-guiding component 300 is switched from the second position to the third position, so that the second air-guiding component 300 and the first air-guiding component 200 can define an air supply channel for supplying air forward. The matching relationship between the first air-guiding component 200 and the second air-guiding component 300 after switching can be seen in Figure 8 .

[0107] Alternatively, if Fig. 9As shown, the air conditioner indoor unit 1000 includes a cooling and sweeping mode, in which the first air guide assembly 200 reciprocates and avoids the bottom portion of the air outlet 110 to supply air downward, and the second air guide assembly 300 is fixed and defines an air supply channel for supplying air forward between the first air guide assembly 200. That is, in the cooling and sweeping mode of the air conditioner indoor unit 1000, the first air guide assembly 200 reciprocates and the second air guide assembly 300 is fixed, and the first air guide assembly 200 can be used to stir the air to increase the sweeping effect, thereby achieving rapid indoor temperature reduction, thereby ensuring the cooling effect of the air conditioner indoor unit 1000.

[0108] Optionally, when the air-conditioning indoor unit 1000 operates in a cooling sweeping mode, the first air guide assembly 200 reciprocates between the fourth position and the sixth position, and the second air guide assembly 300 is fixed at the third position.

[0109] It should be noted that when it is necessary to operate the cooling and sweeping mode of the air-conditioning indoor unit 1000, the positions of the first air guide component 200 and the second air guide component 300 can be first adjusted to the state when the air-conditioning indoor unit 1000 is operated in the cooling mode, and then the first air guide component 200 can be controlled to reciprocate between the fourth position and the sixth position to realize the cooling and sweeping mode of the air-conditioning indoor unit 1000 and reduce the control difficulty of the cooling and sweeping mode.

[0110] In some embodiments of the present invention, Figure 3 As shown, the first air guide component 200 is provided with a plurality of first air dispersion holes 211 arranged at intervals to define a first air dispersion area 210. That is to say, a plurality of first air dispersion holes 211 are provided on the first air guide component 200, and the plurality of first air dispersion holes 211 cooperate to form a first air dispersion area 210 on the first air guide component 200, and the first air dispersion area 210 is used to improve the air dispersion effect of the first air guide component 200, thereby realizing a windless feeling function, avoiding air from blowing directly on the user, ensuring the comfort of the air conditioner indoor unit 1000, and thus improving the user experience.

[0111] At the same time, the first wind dispersing area 210 can also prevent condensation from occurring on the first wind guiding assembly 200 .

[0112] In some embodiments of the present invention, Figure 3As shown, the second air guide component 300 is provided with a plurality of second air dispersion holes 311 arranged at intervals to define a second air dispersion area 310. That is to say, a plurality of second air dispersion holes 311 are provided on the second air guide component 300, and the plurality of second air dispersion holes 311 cooperate to form a second air dispersion area 310 on the second air guide component 300, and the second air dispersion area 310 is used to improve the air dispersion effect of the second air guide component 300, thereby realizing a windless feeling function, avoiding air from blowing directly on the user, ensuring the comfort of the air conditioner indoor unit 1000, and thus improving the user experience.

[0113] At the same time, the second wind dispersing area 310 can also prevent condensation from occurring on the second air guide assembly 300, thereby preventing condensation from occurring when the air-conditioning indoor unit 1000 is working, thereby ensuring working performance.

[0114] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0115] Optionally, in the windless mode, the angle between the axes of the multiple first air dispersion holes 211 and the vertical direction is in the range of 0° to 45°, and the angle between the axes of the multiple second air dispersion holes 311 and the horizontal direction is in the range of 0° to 45°, so as to achieve the air discharge downward or rearwardly downward by utilizing the multiple first air dispersion holes 211 and the air discharge forward or forwardly upward by utilizing the multiple second air dispersion holes 311, so as to ensure the air discharge range and the air volume at the same time.

[0116] In a specific embodiment, the axes of the multiple first air dispersion holes 211 are parallel to the vertical direction, and the axes of the multiple second air dispersion holes 311 are parallel to the horizontal direction, that is, the angle between the axes of the multiple first air dispersion holes 211 and the vertical direction is 0°, and the angle between the axes of the multiple second air dispersion holes 311 and the horizontal direction is 0°, thereby ensuring the air outlet range.

[0117] Specifically, when the air-conditioning indoor unit 1000 is operated in the windless mode, since both the first air guide component 200 and the second air guide component 300 are provided with air dispersion holes, the fan can first be used to drive the indoor normal temperature air into the outer casing 100, and the normal temperature air is discharged through multiple first air dispersion holes 211 and multiple second air dispersion holes 311 after heat exchange by the heat exchanger to ensure the air outlet effect.

[0118] The control method of the air conditioner indoor unit 1000 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0119] like Fig.10 As shown, according to a control method of an air conditioner indoor unit 1000 according to an embodiment of the present invention, the air conditioner indoor unit 1000 is the aforementioned air conditioner indoor unit 1000, and the specific structure of the air conditioner indoor unit 1000 is not described in detail herein. The control method includes:

[0120] receiving a switching instruction for switching between a no-wind mode and an anti-direct-blow mode;

[0121] The second air guide assembly 300 is controlled to rotate to achieve mode switching.

[0122] That is to say, when the air-conditioning indoor unit 1000 receives a signal to switch between the windless mode and the anti-direct blowing mode, the switching can be achieved by directly controlling the rotation of the second air guide component 300. During the switching process, there is no need to adjust the position of the first air guide component 200, so as to reduce the difficulty of adjusting the position of the second air guide component 300 and improve the convenience of position adjustment. At the same time, it can also avoid the air outlet direction and air outlet volume from changing drastically when the air-conditioning indoor unit 1000 switches between the windless mode and the anti-direct blowing mode, thereby ensuring the air outlet effect.

[0123] It can be seen from the above method that the control method of the air-conditioning indoor unit 1000 of the embodiment of the present invention can realize the switching between the windless mode and the anti-direct blowing mode by controlling the rotation of the second air guide component 300, so that during the mode switching process of the air-conditioning indoor unit 1000, the position adjustment of the air guide component is simple and convenient, thereby reducing the difficulty of mode switching of the air-conditioning indoor unit 1000, ensuring the air outlet stability of the air-conditioning indoor unit 1000, and improving the comfort of the air-conditioning indoor unit 1000.

[0124] It should be noted that the switching between the windless mode and the anti-direct blowing mode mentioned above can be switching from the windless mode to the anti-direct blowing mode, or from the anti-direct blowing mode to the windless mode. When the air conditioner indoor unit 1000 switches from the windless mode to the anti-direct blowing mode, the second air guide component 300 can be controlled to rotate counterclockwise relative to the first air guide component 200 and rotate to the third position to achieve the mode switching, and enable the second air guide component 300 and the first air guide component 200 to define an air supply channel for forward air supply; when the air conditioner indoor unit 1000 switches from the anti-direct blowing mode to the windless mode, the second air guide component 300 can be controlled to rotate clockwise relative to the first air guide component 200 and rotate to the second position to achieve the mode switching, and achieve the overlap of the lower end of the second air guide component 300 with the front end of the first air guide component 200.

[0125] In addition, the switching between the windless mode and the anti-direct blowing mode can also be that the air-conditioning indoor unit 1000 cyclically switches between the windless mode and the anti-direct blowing mode, that is, the second air guide component 300 cyclically rotates between the second position and the third position to utilize the second air guide component 300 to sweep the air and ensure the wind outlet effect.

[0126] In some embodiments, when the air conditioner indoor unit 1000 is operated in the windless mode alone, the control method includes: receiving a switching instruction to switch to the windless mode; controlling the first air guide assembly 200 to rotate to supply air downward; controlling the lower end of the second air guide assembly 300 to rotate to overlap with the front end of the first air guide assembly 200, and the upper end of the second air guide assembly 300 to cooperate with the inner wall of the air outlet 110. That is, when the air conditioner indoor unit 1000 receives the instruction to operate the windless mode, the first air guide assembly 200 is controlled to rotate to the first position to send the air dispersed by the first wind dispersion area 210 downward, and the second air guide assembly 300 is controlled to rotate to overlap with the front end of the first air guide assembly 200, and the upper end of the second air guide assembly 300 is matched with the inner wall of the air outlet 110. At this time, the air in the housing 100 is discharged through the first air guide assembly 200 and the second air guide assembly 300, ensuring the windless effect.

[0127] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to operate in the windless mode, the first air guide assembly 200 is controlled to rotate to the first position and the second air guide assembly 300 is controlled to rotate to the second position.

[0128] In some embodiments, when the air conditioner indoor unit 1000 is operated in the anti-direct blowing mode alone, the control method includes: receiving a switching instruction to switch to the anti-direct blowing mode; controlling the first air guide component 200 to rotate to supply air downward; controlling the second air guide component 300 to rotate to define an air supply channel for supplying air forward between the first air guide component 200. That is, when the air conditioner indoor unit 1000 receives a request to operate the anti-direct blowing mode, the first air guide component 200 is controlled to rotate to the first position to supply air downward after being dispersed by the first wind dispersion area 210, and the second air guide component 300 is controlled to rotate to define an air supply channel for supplying air forward between the first air guide component 200 and the first air guide component 200. At this time, part of the air in the housing 100 is discharged through the first air guide component 200, and the other part is discharged through the air supply channel. While ensuring the air output, the air can also be prevented from blowing directly to the user, thereby achieving the effect of preventing direct blowing.

[0129] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to operate the anti-direct blowing mode, the first air guide assembly 200 is controlled to rotate to the first position and the second air guide assembly 300 is controlled to rotate to the third position.

[0130] It should be noted that when the air-conditioning indoor unit 1000 is in the shutdown mode and receives a switching command to switch to the windless mode, the first air guide component 200 and the second air guide component 300 can be controlled to be fixed and directly discharge air; when the air-conditioning indoor unit 1000 is in the shutdown mode and receives a switching command to switch to the anti-direct blowing mode, the first air guide component 200 can be controlled to be fixed and only the second air guide component 300 can be controlled to rotate from the second position to the third position and then discharge air.

[0131] That is to say, when the air-conditioning indoor unit 1000 of the present application turns on the windless mode in the off state, there is no need to control the action of the air guide component. When the anti-direct blowing mode is turned on in the off state, it is only necessary to control the action of one of the air guide components. This makes the control of the air-conditioning indoor unit 1000 simple and the switching response speed between modes fast.

[0132] In some embodiments of the present invention, the air-conditioning indoor unit 1000 includes a heating mode, and the control method further includes: receiving a switching instruction to switch to the heating mode; controlling the first air guide component 200 to rotate counterclockwise so that the first air guide component 200 avoids the bottom portion of the air outlet 110 and controlling the second air guide component 300 to be located on the front side of the first air guide component 200 to block the front portion of the air outlet 110. That is to say, when the air-conditioning indoor unit 1000 receives a signal to operate in the heating mode, the first air guide component 200 and the second air guide component 300 are respectively controlled to rotate so that the first air guide component 200 avoids the bottom part of the air outlet 110, thereby realizing the use of the air outlet 110 to discharge air downward, and the second air guide component 300 is rotated to the front side of the first air guide component 200, so that part of the structure of the first air guide component 200 and the second air guide component 300 can overlap, avoiding a large amount of air from being discharged from the first wind dispersion area 210 and the second wind dispersion area 310, thereby achieving the purpose of compressing the air, thereby increasing the air outlet at the bottom of the air outlet 110 and ensuring the heating effect.

[0133] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to operate in a heating mode, the first air guide assembly 200 is controlled to rotate to the fourth position and the second air guide assembly 300 is controlled to rotate to the fifth position.

[0134] Optionally, the air conditioning indoor unit 1000 includes a heating sweeping mode, and the control method also includes: receiving a switching instruction to switch to the heating sweeping mode; controlling the first air guide component 200 to rotate back and forth and making the first air guide component 200 avoid the bottom part of the air outlet 110; controlling the second air guide component 300 to rotate back and forth and making the second air guide component 300 and the first air guide component 200 spaced apart to define an air guide channel for supplying air downward. That is to say, when the air-conditioning indoor unit 1000 receives a signal to run the heating and sweeping mode, the first air guide component 200 and the second air guide component 300 are respectively controlled to rotate back and forth, and at the same time, during the reciprocating swing of the first air guide component 200, it is ensured that the first air guide component 200 can avoid the bottom part of the air outlet 110, so as to realize the downward air discharge through the air outlet 110, and during the reciprocating swing of the second air guide component 300, it is ensured that the second air guide component 300 can be spaced apart from the first air guide component 200 to define an air guide channel for supplying air downward, so that the bottom part of the air outlet 110 and the air guide channel can both discharge air toward the indoor floor, further realizing rapid indoor temperature rise, thereby ensuring the heating effect of the air-conditioning indoor unit 1000.

[0135] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to operate the heating sweeping mode, the first air guide component 200 is first controlled to rotate to the fourth position and the second air guide component 300 is controlled to rotate to the fifth position. Then, the first air guide component 200 is controlled to rotate back and forth between the fourth position and the sixth position and the second air guide component 300 is controlled to rotate back and forth between the fifth position and the third position.

[0136] Optionally, in the heating sweeping mode, the control method further comprises controlling the first air guide assembly 200 and the second air guide assembly 300 to rotate in linkage. That is, when the air conditioner indoor unit 1000 receives a signal to operate the heating sweeping mode, the first air guide assembly 200 and the second air guide assembly 300 are controlled to rotate synchronously, so that the control difficulty of the first air guide assembly 200 and the second air guide assembly 300 is reduced, and a large range of air stirring can be achieved, thereby increasing the sweeping effect and achieving rapid indoor temperature rise.

[0137] In some embodiments of the present invention, the air conditioner indoor unit 1000 includes a cooling mode, and the control method further includes: receiving a switching instruction to switch to the cooling mode; controlling the first air guide assembly 200 to rotate counterclockwise so that the first air guide assembly 200 avoids the bottom part of the air outlet 110 and controlling the second air guide assembly 300 to rotate to define an air supply channel for sending air forward between the first air guide assembly 200. That is, when the air conditioner indoor unit 1000 receives a request to run the cooling mode, the first air guide assembly 200 and the second air guide assembly 300 are respectively controlled to rotate so that the first air guide assembly 200 avoids the bottom part of the air outlet 110, thereby realizing the use of the air outlet 110 to discharge air downward, and the second air guide assembly 300 is rotated to define an air supply channel for sending air forward between the first air guide assembly 200, at which time the air outlet 110 can be used to simultaneously send air to the front and bottom of the room, thereby ensuring the air volume, thereby realizing rapid cooling of the room and ensuring the comfort of the air conditioner indoor unit 1000.

[0138] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to operate in cooling mode, the first air guide assembly 200 is controlled to rotate to the sixth position and the second air guide assembly 300 is controlled to rotate to the third position.

[0139] Optionally, the air-conditioning indoor unit 1000 includes a cooling and sweeping air mode, and the control method further includes: receiving a switching instruction to switch to the cooling and sweeping air mode; controlling the first air guide component 200 to rotate back and forth and making the first air guide component 200 avoid the bottom part of the air outlet 110; controlling the second air guide component 300 to rotate to define an air supply channel for supplying air forward between the first air guide component 200. That is to say, when the air-conditioning indoor unit 1000 receives a signal to run the cooling sweeping mode, the second air guide component 300 is controlled to rotate to define an air supply channel for supplying air forwards between the second air guide component 300 and the first air guide component 200, and the first air guide component 200 is controlled to rotate back and forth at the same time. However, during the reciprocating rotation of the first air guide component 200, the first air guide component 200 is always kept away from the bottom part of the air outlet 110. In this way, while the air outlet 110 is used to discharge air downward, the first air guide component 200 can also be used to stir the air, thereby increasing the sweeping effect and achieving rapid cooling of the room, thereby ensuring the cooling effect of the air-conditioning indoor unit 1000.

[0140] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to run the cooling sweeping mode, it first controls the first air guide component 200 to rotate to the sixth position and controls the second air guide component 300 to rotate to the third position, and then controls the first air guide component 200 to rotate back and forth between the fourth position and the sixth position.

[0141] In some embodiments, the air conditioner indoor unit 1000 further includes a shutdown mode, and the control method further includes: receiving a switching instruction to switch to the shutdown mode; controlling the first air guide assembly 200 to rotate to a state of downward air supply; controlling the lower end of the second air guide assembly 300 to rotate to overlap with the front end of the first air guide assembly 200, and the upper end of the second air guide assembly 300 to cooperate with the inner wall of the air outlet 110. That is, when the air conditioner indoor unit 1000 receives a signal to switch to the shutdown state, the first air guide assembly 200 is controlled to rotate to a state of downward air supply and the second air guide assembly 300 is controlled to rotate to overlap with the front end of the first air guide assembly 200. At this time, the first air guide assembly 200 and the second air guide assembly 300 can be used to cooperate to block the air outlet 110 to prevent foreign objects, dust, etc. in the room from entering the housing 100 through the air outlet 110, and at the same time, it can also prevent the user from visually observing the structural parts in the housing 100.

[0142] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to run the shutdown mode, the first air guide assembly 200 is controlled to rotate to the first position and the second air guide assembly 300 is controlled to rotate to the second position.

[0143] In some embodiments, the air conditioner indoor unit 1000 further includes an intelligent mode, and the control method further includes: receiving a switching instruction to switch to the intelligent mode; and controlling the first air guide assembly 200 to rotate to a state of sending air downward to shield the bottom portion of the air outlet 110. That is, when the air conditioner indoor unit 1000 receives a signal to switch to the intelligent mode, the first air guide assembly 200 is controlled to rotate to a state of sending air downward to shield the bottom portion of the air outlet 110, thereby preventing the air outlet 110 from directly discharging air downward. In this way, when there is a user below the air outlet 110, air can be prevented from blowing directly onto the user, thereby improving the user experience.

[0144] In a specific embodiment, when the air conditioner indoor unit 1000 receives a signal to run the smart mode, the first air guide component 200 is controlled to rotate to the first position so that the air at the air outlet 110 is dispersed through the first air guide component 200 and then discharged.

[0145] Optionally, the air conditioning indoor unit 1000 further includes a detection component, which is disposed on the housing 100 , and is used to detect whether there is a user below the air outlet 110 , thereby determining whether to turn on the smart mode of the air conditioning indoor unit 1000 .

[0146] In a specific embodiment, when the detection component detects that there is a user below the air outlet 110, the detection component sends a signal to enable the air conditioner indoor unit 1000 to operate in the smart mode.

[0147] The specific type of the detection component is not limited in this application, as long as the detection component can effectively detect whether there is a user under the air outlet 110.

[0148] It should be noted that when the air-conditioning indoor unit 1000 operates in the windless mode, the anti-direct blowing mode, or switches between the windless mode and the anti-direct blowing mode, the detection component stops detecting. Because in the above modes, the first air guide component 200 is always in a state of supplying air downward, thereby reducing the detection difficulty of the detection component, reducing the frequency of use of the detection component, and extending the service life of the detection component.
