[0057] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0058] Reference below Figure 1-Figure 12 The air conditioner indoor unit 100 according to the embodiment of the present invention is described, and the air conditioner indoor unit 100 can cool and heat indoor air.

[0059] like Figure 1-Figure 3 , Figure 6 As shown, the air conditioner indoor unit 100 according to the embodiment of the present invention includes: a casing 1, a fan assembly 2, a first driving mechanism 4 and a first opening and closing door 3.

[0060] Among them, the housing 1 may be provided with an air inlet 12a and a first air outlet 11a, and the housing 1 may be provided with an air duct flow path connected with the air inlet 12a and the first air outlet 11a, and the fan assembly 2 may be arranged in the housing 1 to guide the air flow to flow in the air duct flow path. Specifically, when the air conditioner indoor unit 100 is working, the fan assembly 2 can rotate to form a negative pressure in the air duct flow path, and under the action of the negative pressure, the air flow can enter the air flow path through the air inlet 12a, and the air flow can be discharged through the first air outlet 11a after the air flow in the air flow path is completed.

[0061] like Figure 6As shown, in a specific example of the present invention, the housing 1 may include a front panel 11 and a back panel assembly 12, and the front panel 11 may be snap-fitted with the back panel assembly 12. An air inlet 12a may be provided on the back panel assembly 12, and an air inlet grille 121 is provided at the air inlet 12a. A first air outlet 11a may be provided on the front panel 11, and an air duct flow path connected to the first air outlet 11a and the air inlet 12a may be provided in the housing 1, and a heat exchange component 7 is also provided in the air duct flow path. The heat exchange component 7 can exchange heat with the air flow in the air duct flow path, and the air flow after heat exchange can be discharged through the first air outlet 11a, thereby achieving the purpose of adjusting the indoor temperature.

[0062] like Figure 4-Figure 6 As shown, the first drive mechanism 4 can be arranged in the housing 1, and the first drive mechanism 4 can be connected to the first switch door 3 to drive the first switch door 3 to move relative to the housing 1. The first switch door 3 can have an open state and a closed state. The first drive mechanism 4 can drive the first switch door 3 to move outward relative to the housing 1 (such as Figure 3 The first opening and closing door 3 is moved forward (as shown) to open the first air outlet 11a so that the first opening and closing door 3 is in an open state. When the first opening and closing door 3 is in an open state, the first driving mechanism 4 can drive the first opening and closing door 3 to rotate relative to the housing 1 to adjust the air outlet angle of the first air outlet 11a. When the first opening and closing door 3 is in a closed state, the first opening and closing door 3 can cooperate with the housing 1 to close the first air outlet 11a.

[0063] Specifically, the first drive mechanism 4 may have two movement steps. In the first movement step, the first drive mechanism 4 may drive the first switch door 3 to move forward to open the first air outlet 11a, and the first switch door 3 may be in an open state. When the first switch door 3 is in an open state, the first drive mechanism 4 may perform a second movement step, and the first drive mechanism 4 may continue to drive the first switch door 3 to rotate the first switch door 3 relative to the housing 1, thereby adjusting the air outlet angle of the first air outlet 11a. When the air flow flows outward through the first air outlet 11a, the first switch door 3 may play a role in guiding the air flow, and the air flow may flow along the air outlet angle defined by the first switch door 3. When the air conditioner indoor unit 100 stops working, the first drive mechanism 4 may drive the first switch door 3 to move backward, and the first switch door 3 may cooperate with the housing 1 to close the first air outlet 11a.

[0064] Thus, through the above arrangement, the first drive mechanism 4 can control the first opening and closing door 3 to move relative to the housing 1, which can not only realize the opening and closing of the first air outlet 11a, but also adjust the air outlet angle of the first air outlet 11a, so that the user can select the air outlet angle of the first air outlet 11a according to the distribution of the indoor crowd, and the operation is more convenient. Moreover, the driving method of the first opening and closing door 3 can also solve the problem of the single opening and closing method of the opening and closing door of the air conditioner indoor unit 100 and the poor sense of product technology, which can cater to the consumer psychology of consumers.

[0065] It should be noted that the two movement steps of the first drive mechanism 4 can be controlled separately, and the two movement steps of the first drive mechanism 4 can also be linked. For example, when the user does not need to adjust the outlet angle of the first air outlet 11a, the first drive mechanism 4 can only perform the first movement step, and the first drive mechanism 4 can drive the first switch door 3 to move forward to open the first air outlet 11a. At this time, after the air flow is blown out through the first air outlet 11a, it can be dispersed to the surroundings along the circumferential direction of the first switch door 3, so that the air flow can be evenly circulated to all corners of the indoor space, and the indoor temperature distribution can be more uniform. Moreover, the first switch door 3 can also prevent the air flow from blowing directly to the indoor user and causing discomfort, greatly improving the use comfort of the air conditioner indoor unit 100. When the user needs to adjust the outlet angle of the first air outlet 11a, if the first switch door 3 is in an open state, the first drive mechanism 4 can then perform the second movement step, and the first drive mechanism 4 can continue to drive the first switch door 3 to rotate the first switch door 3 relative to the housing 1. When the user needs to adjust the air outlet angle of the first air outlet 11a, if the first switch door 3 is in a closed state, the two movement steps of the first driving mechanism 4 can be linked, and the first movement step and the second movement step can be executed at one time, thereby making the operation of the air-conditioning indoor unit 100 more convenient.

[0066] According to the air conditioner indoor unit 100 of the embodiment of the present invention, by setting the first driving mechanism 4 and the first switch door 3, the first driving mechanism 4 can control the first switch door 3 to move relative to the housing 1, not only can the first air outlet 11a be opened and closed, but also the air outlet angle of the first air outlet 11a can be adjusted. The user can select the air outlet angle of the first air outlet 11a according to the distribution of the indoor crowd, and the operation is relatively convenient. Moreover, the driving method of the first switch door 3 can also solve the problem of the single switch door switch method and poor product technology sense of the air conditioner indoor unit 100, which can cater to the consumer psychology of consumers.

[0067] like Figure 6As shown, according to some embodiments of the present invention, the first switch door 3 may include a guide member 31 and a closing member 32. The guide member 31 may be connected to the first driving mechanism 4 to be driven to move by the first driving mechanism 4. When the first switch door 3 is in an open state, the outer peripheral wall of the guide member 31 may guide the air flow. The closing member 32 may be connected to the guide member 31. When the first switch door 3 is in a closed state, the closing member 32 may cooperate with the casing 1 to close the first air outlet 11a. Therefore, through the above-mentioned arrangement, the design form of the first switch door 3 can be made simpler, and the guide effect of the first switch door 3 can also be improved.

[0068] Specifically, when the first switch door 3 is in an open state, an air outlet area of ​​the first air outlet 11a can be defined between the guide member 31 and the casing 1, and the air flow can be blown outward along the outer peripheral wall of the guide member 31. The guide member 31 can guide the air flow, thereby not only reducing the circulation resistance of the air flow and improving the air outlet efficiency of the first air outlet 11a, but also the guide member 31 can have a good wind dispersion effect. The air flow can be dispersed to the surroundings in the circumferential direction of the guide member 31, which can make the temperature distribution in the room more uniform.

[0069] Among them, when the first switch door 3 is in a closed state, the closure member 32 can cooperate with the housing 1 to seal the first air outlet 11a, thereby protecting the air conditioner indoor unit 100 and preventing dust and dirt in the air from entering the air conditioner indoor unit 100 through the first air outlet 11a. Optionally, the first air outlet 11a can be formed in a circular shape, the closure member 32 can be formed in a disc shape, and the outer diameter of the closure member 32 can be greater than the diameter of the first air outlet 11a, thereby improving the sealing effect of the first air outlet 11a. Optionally, the closure member 32 can be formed as an integral part with the guide member 31, and the closure member 32 can also be connected to the guide member 31 by screw connection or riveting.

[0070] like Figure 5 As shown, in some embodiments of the present invention, along the direction from the air inlet 12a to the first air outlet 11a (such as Figure 5 The vertical cross-sectional area of ​​the guide member 31 can be gradually increased (from the back to the front direction shown), thereby improving the guiding effect of the guide member 31 and preventing the air flow from blowing directly forward to the user and causing discomfort to the user.

[0071] For example, Fig.10As shown, the guide member 31 may include a mounting portion 311 and a guide portion 312, wherein the mounting portion 311 and the guide portion 312 may be sequentially connected in a direction from the back to the front, and the mounting portion 311 may be slidably matched with the housing 1. Among them, the mounting portion 311 is formed in a cylindrical shape, and the guide portion 312 is formed in a truncated cone shape. In the direction from the back to the front, the vertical cross-sectional area of ​​the guide portion 312 gradually increases, and the guide portion 312 is roughly formed in a trumpet shape. Thus, when the air flow flows out through the first air outlet 11a, the air flow can be dispersed and circulated along the outer peripheral wall of the guide portion 312 toward the surroundings of the first air outlet 11a, which can achieve a good wind dispersing effect. Optionally, the front end of the guide portion 312 may be provided with a plurality of screw columns 312a spaced apart in its circumferential direction, and the closure member 32 may be connected to the guide portion 312 by screw connection.

[0072] like Fig.12 As shown, in some embodiments of the present invention, the closure member 32 may be provided with a plurality of first air outlet micro-holes 32a distributed at intervals, and each first air outlet micro-hole 32a may be arranged in the thickness direction of the closure member 32 (eg Fig.12 The sealing member 32 is penetrated in the front-to-back direction (as shown in the figure), and an air guide channel connected to multiple first air outlet micropores 32a can be provided in the guide member 31, thereby achieving a windless air supply effect, which can greatly improve the user's comfort.

[0073] Specifically, the air conditioner indoor unit 100 can have a first normal air supply mode and a first windless mode. When the air conditioner indoor unit 100 is in the first normal air supply mode, the first switch door 3 is in an open state, and the first drive mechanism 4 can drive the first switch door 3 to move forward to a set position to open the first air outlet 11a, and a part of the air flow can be dispersed and circulated around the first air outlet 11a along the guide member 31, and another part of the air flow can enter the air guide channel and flow out through a plurality of first air outlet micropores 32a. When the air conditioner indoor unit 100 is in the first windless mode, the first switch door 3 is in a closed state, and the air flow can enter the air guide channel and be discharged through a plurality of first air outlet micropores 32a. It can be understood that the plurality of first air outlet micropores 32a can separate the air flow into a plurality of small branch air flows, and the aperture of the first air outlet micropores 32a is small, which can reduce the speed of the air flow, and the air flow can flow out slowly from the plurality of air outlet micropores. This can achieve a windless air supply effect, prevent air flow from blowing directly to indoor users and causing discomfort, make the indoor temperature distribution more uniform, and greatly improve the user experience.

[0074] Of course, it is understandable that when the air-conditioning indoor unit 100 is in the first normal air supply mode, the first drive mechanism 4 can only execute the first movement step (the first switch door 3 is switched from a closed state to an open state), and the first drive mechanism 4 can also execute the first movement step and the second movement step (after the first switch door 3 is switched to the open state, the first drive mechanism 4 drives the first switch door 3 to rotate relative to the casing 1 to adjust the air outlet angle of the first air outlet 11a), and the setting can be selected according to actual usage requirements.

[0075] Optionally, when the air conditioner indoor unit 100 is in cooling mode, in order to prevent the cold air from blowing directly to the indoor user, the air conditioner indoor unit 100 can be adjusted to the first windless mode, and the cold air can slowly flow into the indoor space through the plurality of first air outlet micropores 32a. When the air conditioner indoor unit 100 is in heating mode, since the air density of the hot air is small and the circulation speed is slow, the air conditioner indoor unit 100 can be adjusted to the first normal air supply mode, and the hot air can quickly flow into the indoor space through the first air outlet 11a, thereby improving the heating efficiency of the air conditioner indoor unit 100.

[0076] like Figure 7 As shown, according to some embodiments of the present invention, the first driving mechanism 4 may include a first driving member 41 and a second driving member 42. The first driving member 41 can be connected to the first switch door 3 to drive the first switch door 3 to move horizontally relative to the casing 1. The second driving member 42 can be connected to the first switch door 3. When the first driving member 41 drives the first switch door 3 to move horizontally outward by a preset distance, the second driving member 42 can drive the first switch door 3 to rotate relative to the casing 1. Therefore, through the above-mentioned arrangement, the design of the first driving mechanism 4 can be simpler and the operation can be more convenient.

[0077] In some embodiments of the present invention, the first switch door 3 can be rotatably connected to the first driving member 41, and the second driving member 42 can drive the first switch door 3 to move forward and backward. After the first driving member 41 and the second driving member 42 jointly drive the first switch door 3 to move outward by a preset distance, the second driving member 42 can continue to drive the first switch door 3 to rotate relative to the first driving member 41. Specifically, when the first switch door 3 is switched from a closed state to an open state, the first driving member 41 and the second driving member 42 can simultaneously drive the first switch door 3 to move forward to open the first air outlet 11a. After the first switch door 3 moves outward by a preset distance, the first driving member 41 can stop driving, and the second driving member 42 can continue to drive the first switch door 3 to rotate relative to the housing 1, thereby conveniently adjusting the air outlet angle of the first air outlet 11a.

[0078] It should be noted that the driving method of the first switch door 3 by the first driving member 41 and the second driving member 42 is not limited to this. For example, when the first switch door 3 is switched from the closed state to the open state, the first driving member 41 works and the second driving member 42 does not work, and the first driving member 41 alone drives the first switch door 3 to move outward. After the first switch door 3 moves outward by a preset distance, the first driving member 41 can stop driving. At this time, the second driving member 42 starts to work, and the second driving member 42 can drive the first switch door 3 to rotate relative to the housing 1.

[0079] like Figure 7 As shown, in some embodiments of the present invention, the fan assembly 2 may include an air outlet duct member 26, and the air outlet duct member 26 may be arranged opposite to the first air outlet 11a. The air outlet duct member 26 may have an installation space 26a, and the first drive mechanism 4 may be arranged in the installation space 26a. Therefore, through the above-mentioned arrangement, the matching structure of the first drive mechanism 4 and the fan assembly 2 can be made more compact, which can save the assembly space in the air-conditioning indoor unit 100.

[0080] For example, Figure 7 As shown, the air outlet duct member 26 can be formed into a circular ring, and an installation space 26a can be defined in the air outlet duct member 26, and the first drive mechanism 4 can be arranged in the installation space 26a. The air outlet duct member 26 can also include a plurality of air outlet louvers 261 distributed at intervals, and the plurality of air outlet louvers 261 are located around the installation space 26a and are distributed at intervals in the circumferential direction of the air outlet duct member 26, and the air outlet louvers 261 can play a role in guiding and changing the air outlet angle. Among them, the installation space 26a can be connected to the air duct flow path, and the installation space 26a can also be spaced apart from the air duct flow path. When the first air outlet micropore 32a is provided on the closure member 32, the installation space 26a can be connected to the air duct flow path, and the air flow in the air duct flow path can enter the installation space 26a and be discharged through the first air outlet micropore 32a. When the installation space 26a is spaced apart from the air duct flow path, the air flow can enter the indoor space through the air outlet space defined between the guide member 31 and the housing 1.

[0081] like Figure 7 As shown, according to some embodiments of the present invention, the first driving member 41 may include a first driving motor 415, a first driving gear 411 and a first rack 412. The first driving motor 415 may be disposed in the housing 1, the first driving gear 411 may be connected to the first driving motor 415 to be driven to rotate by the first driving motor 415, and the first rack 412 may be moved along the moving direction of the first switch door 3 (such as Figure 7The first rack 412 can be meshed with the first driving gear 411 to be driven to move by the first driving gear 411, and one end of the first rack 412 can be connected to the first switch door 3 to drive the first switch door 3 to move. Therefore, through the above arrangement, the design form of the first driving member 41 can be simpler. The first driving member 41 drives the first switch door 3 to move by using a driving form in which a gear rack is matched, which can make the operation of the first switch door 3 more stable and reduce the working noise of the air conditioner indoor unit 100.

[0082] Optionally, the first drive member 41 may include two pairs of first drive gears 411 and first racks 412 that match one to one, and the two pairs of first drive gears 411 and first racks 412 may be spaced and respectively connected to the first switch door 3. Thus, the matching structure between the first drive member 41 and the first switch door 3 can be made more solid, and the operation of the first switch door 3 can be made more stable. Further, the first drive member 41 may include a first drive motor 415, the first drive motor 415 is a double-axis motor, and the two motor shafts of the first drive motor 415 have the same rotation direction and are respectively connected to one of the first drive gears 411 by a key. Thus, through the above arrangement, the overall structure of the first drive member 41 can be made more compact, and the operation uniformity of the two first racks 412 can also be improved. Of course, the first drive member 41 may also include two first drive motors 415 that can run synchronously, each of the first drive motors 415 is a single-axis motor, and each of the first drive motors 415 is connected to the corresponding first drive gear 411.

[0083] exist Fig.10In the specific example shown, the first switch door 3 may further include a first connecting frame 33 and a second connecting frame 34, which are respectively arranged on the guide member 31 and spaced apart in the circumferential direction of the guide member 31. The first connecting frame 33 is provided with a first mounting hole 331, and the second connecting frame 34 is provided with a second mounting hole 341. The first driving mechanism 4 includes two pairs of first driving gears 411 and first racks 412 that match one to one, and a first driving motor 415, the first driving motor 415 is a double-shaft motor, and the two motor shafts of the first driving motor 415 have the same rotation direction and are respectively key-connected with one of the first driving gears 411. Each first rack 412 is provided with a matching column 412b. When the first driving mechanism 4 is assembled with the first switch door 3, the matching column 412b on one of the first racks 412 can be inserted into the first mounting hole 331 on the first connecting frame 33, and the matching column 412b on the other first rack 412 can be inserted into the second mounting hole 341 on the second connecting frame 34. Therefore, through the above arrangement, the connection structure between the first driving mechanism 4 and the first opening and closing door 3 can be made simpler, which can greatly improve the assembly efficiency of the air-conditioning indoor unit 100.

[0084] It should be noted that the design form of the first driving member 41 is not limited to this, as long as it can drive the first switch door 3 to move forward and backward. For example, the first driving member 41 can also be a linear motor or a hydraulic drive cylinder, one end of the linear motor or the hydraulic drive cylinder can be connected to the housing 1, and the other end of the linear motor or the hydraulic drive cylinder can be connected to the first switch door 3, thereby driving the first switch door 3 to flexibly switch between the open state and the closed state.

[0085] like Figure 7-Figure 8 As shown, in some embodiments of the present invention, the first driving member 41 may further include a rack box 414, the rack box 414 may be connected to the air outlet duct member 26, the rack box 414 may be provided with a guide hole 414a, the first rack 412 may pass through the guide hole 414a to reciprocate relative to the rack box 414, the guide hole 414a may guide the first rack 412, and may make the operation of the first rack 412 more regular and smooth, thereby improving the operation stability of the first switch door 3.

[0086] like Figure 7-Figure 8 As shown, in some embodiments of the present invention, the first rack 412 may be provided with a first rack 412 in the moving direction of the first opening and closing door 3 (such as Figure 7-Figure 8The first drive member 41 may further include a stopper rod 413 extending into the stopper groove 412a, and the stopper rod 413 may be slidably matched with the stopper groove 412a. When the first switch door 3 is in the open state, the stopper rod 413 may stop at one end of the stopper groove 412a to limit the first switch door 3. Thus, through the above arrangement, the stopper rod 413 may limit the first rack 412, so that the first switch door 3 can be accurately moved to the set position, and the operation stability of the air conditioner indoor unit 100 can be improved.

[0087] Optionally, a contact sensor (not shown) may be provided on the outer peripheral wall of the stop rod 413, and the contact sensor may be connected to communicate with the first drive motor 415. When the first drive member 41 drives the first switch door 3 to move, the first drive motor 415 may drive the first drive gear 411 to rotate, and the first drive gear 411 meshes with the first rack 412 to drive the first rack 412 to move, and when the first rack 412 moves, the stop rod 413 may slide with the limit groove 412a on the first rack 412. When the first rack 412 moves to the set position, the contact sensor on the stop rod 413 contacts one end of the limit groove 412a, and the contact sensor may transmit the contact signal to the first drive motor 415,

[0088] The first drive motor 415 stops working after receiving the contact signal. Thus, through the above arrangement, the intelligent control of the first drive member 41 can be realized, and the operation of the first drive member 41 can be made more convenient.

[0089] like Figure 7 As shown, in some embodiments of the present invention, the second driving member 42 may include a second driving motor 423, a second driving gear 421 and a second rack 422. The second driving gear 421 can be connected to the second driving motor 423 to be driven to rotate by the second driving motor 423. The second rack 422 can extend along the moving direction of the first switch door 3. The second rack 422 can be meshed with the second driving gear 421 to be driven to move by the second driving gear 421. One end of the second rack 422 is connected to the outer peripheral edge of the first switch door 3 to drive the first switch door 3 to rotate relative to the first driving member 41. Therefore, through the above-mentioned arrangement, the design form of the second driving member 42 can be simpler. The second driving member 42 adopts a driving form of gear and rack matching to drive the first switch door 3 to rotate relative to the casing 1, which can make the operation of the first switch door 3 more stable, and can also accurately adjust the rotation angle between the first switch door 3 and the casing 1.

[0090] exist Figure 7In the specific example shown, the first driving mechanism 4 includes a first driving member 41 and a second driving member 42, and the second driving member 42 is located above the first driving member 41. The first driving member 41 includes two pairs of first driving gears 411 and first racks 412 that match one to one, and the two pairs of first driving gears 411 and first racks 412 are spaced apart in the radial direction of the air outlet duct member 26 and are respectively connected to the first switch door 3. The first driving member 41 also includes two first driving motors 415 that can run synchronously, each of the first driving motors 415 is a single-axis motor, and each of the first driving motors 415 is connected to the corresponding first driving gear 411 to drive the first driving gear 411 to rotate.

[0091] The second driving member 42 includes a second driving motor 423, a second driving gear 421 and a second rack 422. The second driving gear 421 is connected to the second driving motor 423 to be driven to rotate by the second driving motor 423. The second rack 422 can extend along the moving direction of the first switch door 3. The second rack 422 is meshed with the second driving gear 421 to be driven to move by the second driving gear 421. The first rack 412 and the second rack 422 have the same extending direction.

[0092] like Figure 10-11 As shown, the first switch door 3 includes a first connecting frame 33, a second connecting frame 34 and a third connecting frame 35. The first connecting frame 33 and the second connecting frame 34 are respectively arranged on the guide member 31 and are spaced apart in the circumferential direction of the guide member 31. The third connecting frame 35 is located above the first connecting frame 33 and the second connecting frame 34. Among them, the first connecting frame 33 is provided with a first mounting hole 331, and the second connecting frame 34 is provided with a second mounting hole 341. Each first rack 412 is provided with a matching column 412b. When the first driving mechanism 4 is assembled with the first switch door 3, the matching column 412b on one of the first racks 412 can be inserted into the first mounting hole 331 on the first connecting frame 33, and the matching column 412b on the other first rack 412 can be inserted into the second mounting hole 341 on the second connecting frame 34.

[0093] like Figure 7-Figure 9As shown, the second rack 422 includes a body 4221 and a clamping portion 4222, the second driving gear 421 is meshed with the body 4221, and the clamping portion 4222 is connected to the guide member 31. The clamping portion 4222 includes a first clamping protrusion 4222a and a second clamping protrusion 4222b arranged at intervals in the front-to-back direction. One end of the third connecting frame 35 is connected to the guide member 31, and the other end of the third connecting frame 35 is a connecting end 351 and is connected to the second rack 422. The bottom of the connecting end 351 is provided with an installation opening 351a, and the front and rear side walls of the connecting end 351 are provided with buckle holes 351b. When the second rack 422 is assembled with the third connecting frame 35, the first clamping protrusion 4222a and the second clamping protrusion 4222b can pass through the installation opening 351a and extend into the connecting end 351, and the first clamping protrusion 4222a and the second clamping protrusion 4222b can slide upward and extend into the corresponding buckle hole 351b.

[0094] When the second driving member 42 drives the first switch door 3 to rotate relative to the housing 1, the matching column 412b on the first rack 412 can form a rotational match with the corresponding first mounting hole 331 or second mounting hole 341, so that the first switch door 3 can rotate relative to the housing 1. For example, the second driving member 42 can push the first switch door 3 forward, at which time the air outlet angle of the upper part of the first air outlet 11a increases, and the air outlet angle of the lower part of the first air outlet 11a decreases. Figure 3 As shown, the second driving member 42 can pull the first opening and closing door 3 backwards, at which time the air outlet angle of the upper half of the first air outlet 11a decreases, and the air outlet angle of the lower half of the first air outlet 11a increases.

[0095] It should be noted that the driving method of the second driving member 42 on the first switch door 3 is not limited to this, as long as it can drive the first switch door 3 to rotate relative to the housing 1, the inclination angle between the first switch door 3 and the housing 1 can be selected and set according to actual use requirements. In addition, the present invention does not impose specific restrictions on the connection method between the second rack 422 and the first switch door 3, as long as it can drive the second switch door 5 to rotate relative to the housing 1. For example, an electromagnet can be set at the front end of the second rack 422, and at least a part of the first switch door 3 can be a metal part. When the second driving member 42 drives the first switch door 3 to rotate relative to the housing 1, the electromagnet is powered on, and the electromagnet can be adsorbed on the metal part, so that the second driving member 42 can drive the first switch door 3 to rotate relative to the housing 1. When the first switch door 3 rotates to a set angle, the electromagnet is powered off, and the second rack 422 can be separated from the first switch door 3.

[0096] like Figure 1-Figure 3As shown, according to some embodiments of the present invention, the housing 1 may be provided with a second air outlet 11b, and the air conditioner indoor unit 100 may further include a second switch door 5 and a second drive mechanism 6, and the second drive mechanism 6 may be connected to the second switch door 5 to drive the second switch door 5 to slide relative to the housing 1 to open or close the second air outlet 11b. Thus, through the above arrangement, the air conditioner indoor unit 100 can discharge air through the first air outlet 11a and the second air outlet 11b at the same time, which can improve the air outlet efficiency of the air conditioner indoor unit 100, and can also expand the air supply area of ​​the air conditioner indoor unit 100, so that the indoor temperature distribution can be more uniform.

[0097] like Figure 1 As shown, in some embodiments of the present invention, the first air outlet 11a and the second air outlet 11b can be spaced apart in the vertical direction, and the first air outlet 11a is located above the second air outlet 11b. A first opening and closing door 3 is provided at the first air outlet 11a, and the first opening and closing door 3 can be connected to a first driving mechanism 4, and the first driving mechanism 4 can drive the first opening and closing door 3 to move to open or close the first air outlet 11a, and the first driving mechanism 4 can also drive the first opening and closing door 3 to rotate relative to the housing 1 to adjust the air outlet angle of the first air outlet 11a. A second opening and closing door 5 is provided at the second air outlet 11b, and the second opening and closing door 5 can be connected to a second driving mechanism 6, and the second driving mechanism 6 can drive the second opening and closing door 5 to slide relative to the housing 1 to open or close the second air outlet 11b.

[0098] Among them, the opening and closing states of the first switch door 3 and the second switch door 5 can be controlled respectively. When the air conditioner indoor unit 100 is in the cooling working mode, the second drive mechanism 6 can drive the second switch door 5 to slide to close the second air outlet 11b, and the first drive mechanism 4 can drive the first switch door 3 to move forward to open the first air outlet 11a. It can be understood that since the first air outlet 11a is located above the second air outlet 11b, the cold air can enter the upper half of the indoor space through the first air outlet 11a, and the air density of the cold air is relatively large, and the cold air can flow slowly from top to bottom in the indoor space, thereby not only improving the cooling effect, but also preventing the cold air from blowing directly to the indoor user through the second air outlet 11b and causing discomfort. Further, when the air conditioner indoor unit 100 is in the cooling working mode, the first switch door 3 can also be driven by the first drive mechanism 4 to rotate relative to the housing 1 so that the first air outlet 11a is directed obliquely upward to discharge air, thereby preventing the cold air from blowing directly to the indoor user, and achieving the effect of no wind feeling.

[0099] When the air conditioner indoor unit 100 is in the heating working mode, the second driving mechanism 6 can drive the second switch door 5 to slide to open the second air outlet 11b, and the first driving mechanism 4 can drive the first switch door 3 to move forward to open the first air outlet 11a. Thus, the first air outlet 11a and the second air outlet 11b can discharge air at the same time. It can be understood that since the air density of the hot air is small and the circulation speed is slow, the simultaneous discharge of air from the first air outlet 11a and the second air outlet 11b can improve the heating efficiency of the air conditioner indoor unit 100. In addition, when the air conditioner indoor unit 100 is in the heating working mode, the first switch door 3 can be driven by the first driving mechanism 4 to rotate relative to the casing 1 so that the first air outlet 11a discharges air diagonally downward, thereby allowing the hot air to flow smoothly to the floor, achieving the effect of warming the feet, and greatly improving the user experience.

[0100] It should be noted that the arrangement of the first air outlet 11a and the second air outlet 11b on the air conditioner indoor unit 100 is not limited thereto. For example, the air conditioner indoor unit 100 may be provided with a plurality of first air outlets 11a and a plurality of second air outlets 11b, which may be selected and arranged according to actual use requirements, and the present invention does not impose any specific limitation on this.

[0101] In a specific example of the present invention, the second air outlet 11b is located above the first air outlet 11a, and a first switch door 3 is provided at the first air outlet 11a, and the first switch door 3 can be connected to a first drive mechanism 4, and the first drive mechanism 4 can drive the first switch door 3 to move back and forth to open or close the first air outlet 11a. A second switch door 5 is provided at the second air outlet 11b, and the second switch door 5 can be connected to a second drive mechanism 6, and the second drive mechanism 6 can drive the second switch door 5 to move back and forth to open or close the second air outlet 11b. The second switch door 5 can open the second air outlet 11b by sliding from top to bottom, and close the second air outlet 11b by sliding from bottom to top, and the second switch door 5 can also close the second air outlet 11b by sliding from top to bottom, and open the second air outlet 11b by sliding from bottom to top.

[0102] In some embodiments of the present invention, the second driving mechanism 6 can drive the second switch door 5 to slide in the vertical direction, thereby facilitating the adjustment of the air outlet area of the second air outlet 11b. It can be understood that when the height dimension of the air conditioner indoor unit 100 is relatively large, the second air outlet 11b can extend in the up and down directions, and the air outlet area of the second air outlet 11b can be adjusted by controlling the sliding displacement of the second switch door 5 in the up and down directions, which is more convenient to operate. Of course, the second driving mechanism 6 can also drive the second switch door 5 to slide in the left and right directions, and the second driving mechanism 6 can also drive the second switch door 5 to slide in a direction with a certain inclination angle with respect to the left and right directions and the up and down directions, which can be selected and set according to actual usage requirements, and the present invention does not make specific limitations thereto.

[0103] In addition, when the second switch door 5 opens the second air outlet 11b, the second switch door 5 can be located above the second air outlet 11b, the second switch door 5 can also be located below the second air outlet 11b, the second switch door 5 can also be located on the left side of the second air outlet 11b, and the second switch door 5 can also be located on the right side of the second air outlet 11b, which can be selected and set according to the size of the assembly space inside the cabinet 1.

[0104] As Fig. 9 shown, in some embodiments of the present invention, the second driving mechanism 6 can include a third driving motor (not shown in the figure), a third driving gear 61, and a third rack 62. The third driving gear 61 can be connected to the second driving motor 423 to be driven to rotate by the second driving motor 423. The third rack 62 can extend along the moving direction of the second switch door 5 (such as Figure 6 the up and down direction shown), the third rack 62 can be engaged with the third driving gear 61 to be driven to move by the third driving gear 61, and one end of the third rack 62 can be connected to the second switch door 5 to drive the second switch door 5 to move. Thus, through the above settings, the design form of the second driving mechanism 6 can be made simpler. Moreover, the second driving mechanism 6 drives the second switch door 5 to slide by using a gear-rack structure driving method, which can make the operation of the second switch door 5 more stable.

[0105] Optionally, the second driving mechanism 6 can include two sets of third driving motors, third driving gears 61, and third racks 62 that are correspondingly matched one by one. The two third racks 62 both extend in the up and down directions and are spaced apart in the left and right directions, and the two third racks 62 are both connected to the inner peripheral wall of the second switch door 5. When the second driving mechanism 6 works, the two third driving motors rotate synchronously, and the two third racks 62 drive the second switch door 5 to slide relative to the cabinet 1 at the same time, thereby making the operation of the second switch door 5 more stable.

[0106] In a specific example of the present invention, the air conditioner indoor unit 100 may further include a switch door mounting plate 8, and the second drive mechanism 6 may be arranged on the switch door mounting plate 8. Among them, the third rack 62 may be arranged on the front side wall of the switch door mounting plate 8 and connected to the inner peripheral wall of the second switch door 5. A slide rail (not shown) is provided on the switch door mounting plate 8, and the second switch door 5 slides with the slide rail. Therefore, through the above arrangement, not only can the installation and fixing of the second drive mechanism 6 be facilitated, but the second switch door 5 can also slide with the slide rail to reduce the sliding resistance of the second switch door 5, so that the operation of the second switch door 5 can be smoother, and the workload of the second drive motor 423 can also be reduced.

[0107] It should be noted that the structural design of the second drive mechanism 6 is not limited to this, as long as it can drive the second switch door 5 to slide relative to the housing 1. For example, the second drive mechanism 6 can also be a linear motor or a hydraulic drive cylinder, one end of the linear motor or the hydraulic drive cylinder can be connected to the housing 1, and the other end of the linear motor or the hydraulic drive cylinder can be connected to the second switch door 5, thereby also driving the second switch door 5 to slide relative to the housing 1.

[0108] like Figure 6 As shown, in some embodiments of the present invention, the fan assembly 2 may include a first fan 22 and a second fan 23, the first fan 22 may be arranged opposite to the first air outlet 11a, and the second fan 23 may be arranged opposite to the second air outlet 11b, wherein the working states of the first fan 22 and the second fan 23 may be controlled separately according to usage requirements, thereby improving the user's usage flexibility.

[0109] Optionally, the first fan 22 may be an axial flow fan, an oblique flow fan, or a counter-rotating fan. Optionally, the second fan 23 may be an axial flow fan, an oblique flow fan, or a counter-rotating fan.

[0110] In some embodiments of the present invention, the first fan 22 may be a diagonal flow fan, and the second fan 23 may be a counter-rotating fan, thereby improving the air supply effect of the air conditioner indoor unit 100. It is understandable that the diagonal flow fan supplies air by taking in air axially and discharging air in a direction inclined at a certain angle to the axial direction, and the diagonal flow fan has a large air volume, thereby increasing not only the air volume of the first fan 22, but also the air outlet angle of the first fan 22, thereby expanding the air supply range of the first fan 22.

[0111] The counter-rotating fan may include two wind wheels arranged opposite to each other, and the distribution directions of the blades on the two wind wheels are opposite. When the counter-rotating fan is working, if the rotation directions of the two wind wheels are opposite, the air supply speeds of the two wind wheels in the tangential direction of the rotation direction can offset each other, and the air supply speeds of the two wind wheels in the axial direction can be superimposed on each other, thereby increasing the axial air supply speed of the second fan 23, and then greatly increasing the air supply distance of the second fan 23, so that the second fan 23 can have the effect of long-distance air supply. If the rotation directions of the two wind wheels of the counter-rotating fan are the same, the air supply speeds of the two wind wheels in the tangential direction of the rotation direction can be superimposed on each other, and the air supply speeds of the two wind wheels in the axial direction can offset each other, and the air flow can be dispersed and circulated around the second fan 23, which can prevent the air flow from blowing directly through the second air outlet 11b to the indoor user, thereby achieving a windless air outlet effect, greatly improving the user's comfort.

[0112] Specifically, when one of the wind wheels in the counter-cyclone fan rotates, the other non-working wind wheel in the counter-cyclone fan can also rotate under the action of the airflow. At this time, the two wind wheels rotate in the same direction. According to the above description, the counter-cyclone fan can also achieve the effect of no wind.

[0113] In addition, when the two wind wheels in the counter-rotating fan rotate at a low speed at the same time, the rotation directions of the two wind wheels can be the same, or the rotation directions of the two wind wheels can be opposite, and the wind-free air outlet effect can be achieved. It can be understood that since the rotation speed of the two wind wheels in the counter-rotating fan is low, the circulation speed of the air flow is slow, and the air flow can slowly flow out from the first air outlet 11a, thereby achieving the wind-free effect.

[0114] Thus, through the above arrangement, when it is necessary to increase the air supply angle, the first fan 22 can be turned on, and the first fan 22 can achieve the effect of large-scale air supply. When long-distance air supply is required, the second fan 23 can be turned on, and the rotation directions of the two wind wheels of the second fan 23 can be controlled to be opposite, thereby greatly improving the air supply distance of the second fan 23. When a windless air outlet is required, the rotation directions of the two wind wheels of the second fan 23 can be controlled to be the same, and the second fan 23 can disperse the wind to the surroundings, which can prevent the air flow from blowing directly through the second air outlet 11b to the indoor user. When the first fan 22 and the second fan 23 work at the same time, due to the different air outlet angles of the first air outlet 11a and the second air outlet 11b, the two air flows flowing out of the first air outlet 11a and the second air outlet 11b can be mixed in the indoor space, which can make the indoor temperature distribution more uniform.

[0115] It should be noted that the design of the first fan 22 and the second fan 23 is not limited to this. The first fan 22 can be any one of an axial flow fan, an oblique flow fan and a counter-rotating fan, and the second fan 23 can also be any one of an axial flow fan, an oblique flow fan and a counter-rotating fan, and can be used in combination according to actual use requirements, and the present invention does not make specific restrictions on this.

[0116] exist Figure 6 In the specific example shown, the air conditioner indoor unit 100 may further include an air outlet frame member 21, and the air outlet frame member 21 may be connected to the housing 1. The air outlet frame member 21 is provided with a first air duct member 24 and a second air duct member 25 spaced apart in the up-down direction, the first air duct member 24 is arranged opposite to the first air outlet 11a, and the second air duct member 25 is arranged opposite to the second air outlet 11b. The first fan 22 is arranged in the first air duct member 24, and the second fan 23 is arranged in the second air duct member 25. Thus, through the above arrangement, not only can the installation and fixing of the first fan 22 and the second fan 23 be facilitated, but also the first air duct member 24 and the second air duct member 25 can both play a guiding effect, thereby improving the air supply efficiency of the air conditioner indoor unit 100.

[0117] like Fig.12 As shown, in some embodiments of the present invention, the second opening and closing door 5 may be provided with a plurality of second air outlet micro-holes 5a distributed at intervals, and each second air outlet micro-hole 5a may be arranged in the thickness direction of the second opening and closing door 5 (such as Fig.12 The second switch door 5 is penetrated in the front-to-back direction (as shown in the figure), thereby enabling the air-conditioning indoor unit 100 to achieve a windless air outlet effect, thereby improving the user's comfort.

[0118] Specifically, the air conditioner indoor unit 100 may have a second normal air supply mode and a second windless mode. When the air conditioner indoor unit 100 is in the second normal air supply mode, the second drive mechanism 6 may drive the second switch door 5 to slide relative to the housing 1 to open the second air outlet 11b, and the air flow may be discharged through the second air outlet 11b. When the air conditioner indoor unit 100 is in the second windless mode, the second switch door 5 may cooperate with the housing 1 to close the second air outlet 11b, and the air flow may be discharged through a plurality of second air outlet micropores 5a. It is understandable that the plurality of second air outlet micropores 5a may separate the air flow into a plurality of small branch air flows, and the second air outlet micropores 5a have a small aperture, which may reduce the speed of the air flow, and the air flow may flow out slowly from the plurality of second air outlet micropores 5a. This may achieve a windless air supply effect, prevent the air flow from blowing directly to the indoor user and causing discomfort, and greatly improve the user experience.

[0119] Optionally, when the air conditioner indoor unit 100 is in cooling mode, in order to prevent the cold air from blowing directly to the indoor user, the air conditioner indoor unit 100 can be adjusted to the second windless mode, and the cold air can slowly flow into the indoor space through the plurality of second air outlet micropores 5a. When the air conditioner indoor unit 100 is in heating mode, since the air density of the hot air is small and the circulation speed is slow, the air conditioner indoor unit 100 can be adjusted to the second normal air supply mode, and the hot air can quickly flow into the indoor space through the second air outlet 11b, thereby improving the heating efficiency of the air conditioner indoor unit 100.

[0120] like Fig.12 As shown, in some embodiments of the present invention, the housing 1 may be provided with a plurality of third air outlet micro-holes 11c disposed at intervals on the outer periphery of the second air outlet 11b, and each of the third air outlet micro-holes 11c may be disposed in the thickness direction of the housing 1 (such as Fig.12 The casing 1 is penetrated in the front-to-back direction (as shown in the figure), and each third air outlet micropore 11c can be connected to the air duct flow path, thereby increasing the air supply efficiency of the air-conditioning indoor unit 100, thereby improving the cooling and heating effects of the air-conditioning indoor unit 100 when it is in the second windless mode.

[0121] For example, Fig.12 As shown, the second air outlet 11b can be formed into a circle, and the second switch door 5 is provided with a plurality of second air outlet micropores 5a distributed at intervals, and the plurality of second air outlet micropores 5a are combined to form a circle and are arranged opposite to the second air outlet 11b. The housing 1 is provided with a plurality of third air outlet micropores 11c arranged at intervals on the outer periphery of the second air outlet 11b, and the plurality of third air outlet micropores 11c are located on the outer periphery of the second air outlet 11b and are combined to form a roughly circular ring. Thus, through the above arrangement, the third air outlet micropores 11c on the second switch door 5 and the third air outlet micropores 11c on the housing 1 can discharge air at the same time, which greatly improves the air outlet efficiency of the air conditioner indoor unit 100, and can also make the appearance design of the air conditioner indoor unit 100 more beautiful, and can improve the appearance of the air conditioner indoor unit 100.

[0122] The air conditioner according to the embodiment of the present invention includes the air conditioner indoor unit 100 according to the above-mentioned embodiment of the present invention.

[0123] According to the air conditioner of the embodiment of the present invention, by providing the above-mentioned air conditioner indoor unit 100, not only the product technological sense of the air conditioner can be improved, but also the cooling and heating effects of the air conditioner can be improved, which greatly improves the user's comfort and further improves the market competitiveness of the air conditioner.
