[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments 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.

[0038] The air conditioner indoor unit 100 according to the embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 5 As shown, according to an embodiment of the present invention, the air-conditioning indoor unit 100 includes: a casing 10 , a panel 20 , a driving mechanism 30 and a wind shield 50 .

[0040] The housing 10 is provided with an air outlet 10a and an air inlet 10b. The air conditioner indoor unit 100 draws air from the surrounding space through the air inlet 10b and discharges the air from the air outlet 10a.

[0041] The panel 20 is movably disposed on the front side of the housing 10 , and the panel 20 has a first wind dispersing area 20 a for dispersing wind.

[0042] The first wind dispersing area 20a on the panel 20 is used to disperse the wind, so that the airflow discharged from the air outlet channel 10a disperses after passing through the first wind dispersing area 20a, forming an experience of no wind. For example, the first wind dispersing area 20a includes a plurality of first wind dispersing holes arranged at intervals, and the first wind dispersing holes with smaller apertures disperse the airflow to form an experience of no wind; or the first wind dispersing area 20a includes a first hole structure and a first wind dispersing fan arranged in the first hole structure, and the first wind dispersing fan disperses the airflow to form an experience of no wind.

[0043] The panel 20 is movably disposed on the front side of the housing 10 , and the movable panel 20 increases the user's options, such as forming an experience of no wind feeling or no wind feeling.

[0044] The driving mechanism 30 is disposed on the housing 10 and drives the connection panel 20. In other words, the driving mechanism 30 drives the panel 20 to move.

[0045] The wind shield 50 is movably disposed on the housing 10 and is linked to the driving mechanism 30 or the panel 20 .

[0046] For example, the wind shield 50 can be movably disposed on the casing 10 and linked with the driving mechanism 30, and the driving mechanism 30 drives the wind shield 50 to move, wherein the driving mechanism 30 can drive the wind shield 50 and the panel 20 to move synchronously, or can drive the wind shield 50 and the panel 20 to move separately in stages.

[0047] Alternatively, the wind shield 50 can be movably provided on the casing 10 and linked with the panel 20. The driving mechanism 30 drives the panel 20 to move. The panel 20 is linked with the wind shield 50. The panel 20 drives the wind shield 50 to move, so that the panel 20 and the wind shield 50 move synchronously, which is convenient for control.

[0048] Among them, the air-conditioning indoor unit 100 has a windless mode. When the air-conditioning indoor unit 100 is in the windless mode, the driving mechanism 30 can drive the panel 20 to move to be separated from the casing 10 to define an air guide space 70. The lower end of the air guide space 70 is connected to the air outlet channel 10a, and the wind shield 50 can move between the air outlet end of the air guide space 70 and the air inlet 10b to guide the airflow to the first wind dispersion area 20a.

[0049] Among them, the panel 20 is movable relative to the casing 10. In the windless mode, the panel 20 moves to the front side of the casing 10 and is spaced to define an air guide space 70. Compared with the solution in the related art that the panel part is fixed on the air-conditioning body and forms an air flow channel with the air-conditioning body, the panel 20 of the present application is movable, thereby making the volume of the air guide space 70 larger, further improving the problem of wind resistance.

[0050] In the related art, in order to achieve windless air outlet, an air duct can be formed between the panel and the casing of the indoor unit of the air conditioner, and the airflow blown out of the air outlet can be sent upward along the air duct to avoid the airflow blowing directly on the user, thus achieving windless feeling. However, since the air inlet is arranged at the top of the casing, the air blown upward from the air outlet is easy to enter the air inlet. Due to the large temperature difference between the air blown out of the air outlet and the air at the air inlet, the indoor unit of the air conditioner is prone to cooling short circuit or heating short circuit, causing the temperature sensor at the air inlet to detect the temperature inaccurately, and the controller mistakenly thinks that the indoor temperature is too low or too high, thereby controlling the outdoor unit of the air conditioner to reduce the cooling capacity or increase the heating capacity, resulting in the illusion of insufficient cooling or heating or shutdown, affecting the user experience.

[0051] In the utility model, the air conditioner indoor unit 100 can be used for cooling or heating, so the wind sent out from the air outlet 10a can be cold wind or hot wind. When the air conditioner indoor unit 100 is cooling, the above scheme can reduce the occurrence of cooling short circuit at the air inlet 10b, avoid the temperature detected by the air inlet 10b being lower than the actual temperature, and reduce the occurrence of the phenomenon of controlling the air conditioner outdoor unit to reduce the frequency or shut down due to the false detection of the air inlet 10b temperature being too low. When the air conditioner indoor unit 100 is heating, the above scheme can reduce the probability of heating short circuit at the air inlet 10b, avoid the temperature detected by the air inlet 10b being higher than the actual temperature, and reduce the occurrence of the phenomenon of controlling the air conditioner outdoor unit to increase the frequency or shut down due to the false detection of the air inlet 10b temperature being too high.

[0052] It should be noted that, in the air conditioner indoor unit 100, the air outlet 10a can be arranged at the bottom of the casing 10, the air inlet 10b is arranged at the top of the casing 10, the panel 20 is arranged on the front of the casing 10, and the air guide space 70 formed by the panel 20 and the casing 10 guides the air upward. The air outlet 10a can also be arranged at the front of the casing 10, the air inlet 10b is arranged at the top of the casing 10, the panel 20 is arranged on the front of the casing 10, and the air guide space 70 formed by the panel 20 and the casing 10 guides the air upward.

[0053] Among them, the wind shield 50 is linked with the driving mechanism 30 or the panel 20. The driving mechanism 30 drives both the wind shield 50 and the panel 20. The wind shield 50 and the panel 20 are driven by the driving mechanism 30. With this solution, there is no need to set up a separate driving component for the wind shield 50, which reduces the number of components and simplifies the control strategy while avoiding backflow.

[0054] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, by setting the wind shield 50, the wind shield 50 can be moved to between the air outlet end of the wind guide space 70 and the air inlet 10b, that is, the wind shield 50 can intercept the airflow, avoid the airflow in the wind guide space 70 flowing to the air inlet 10b, reduce the probability of backflow short circuit caused by a large temperature difference in the air at the air inlet 10b, and also avoid the situation where the temperature detected by the temperature sensor at the air inlet 10b is inconsistent with the actual indoor temperature, reduce the situation of incorrect frequency modulation or shutdown of the air-conditioning outdoor unit, so that the air-conditioning indoor unit 100 has a better anti-backflow effect and higher working reliability. At the same time, the wind shield 50 is arranged to be linked with the driving mechanism 30 or the panel 20, the driving mechanism 30 drives both the wind shield 50 and the panel 20, and the wind shield 50 and the panel 20 are uniformly driven by the driving mechanism 30. With this solution, there is no need to set a separate driving component for the wind shield 50, thereby reducing the number of components and simplifying the control strategy while avoiding backflow.

[0055] Reference Figure 5 As shown, in some embodiments, the driving mechanism 30 includes: a first connecting rod 302 , a second connecting rod 303 , a driving member 301 and a third connecting rod 304 .

[0056] The first connecting rod 302 is rotatably disposed on the housing 10 .

[0057] The second connecting rod 303 is rotatably disposed on the housing 10 and is spaced apart from the first connecting rod 302 in the up-down direction.

[0058] The driving member 301 is connected to one of the first connecting rod 302 and the second connecting rod 303 to drive the other to rotate. In other words, the driving member 301 can be connected to the first connecting rod 302, or the driving member 301 can also be connected to the second connecting rod 303.

[0059] The third connecting rod 304 is rotatably connected to the first connecting rod 302 and the second connecting rod 303 , respectively, and the third connecting rod 304 is connected to the panel 20 .

[0060] The windshield 50 is connected to the third connecting rod 304 or the panel 20. In other words, the third connecting rod 304 can be connected to the windshield 50, or the panel 20 can be connected to the windshield 50.

[0061] In the above scheme, the first connecting rod 302, the second connecting rod 303, the third connecting rod 304 and the housing 10 form a parallelogram structure, and the driving member 301 can drive one of the first connecting rod 302 and the second connecting rod 303 to rotate, and at the same time drive the other of the first connecting rod 302 and the second connecting rod 303 to rotate together, so that the panel 20 can be opened in a manner approximately parallel to the housing 10, and a wind guide space 70 is formed between the panel 20 and the housing 10. The use of such a driving mechanism 30 to drive the panel 20 to move has a relatively simple structure and is conducive to reducing costs.

[0062] Optionally, the driving member 301 may be, but is not limited to, a driving motor, a rotary cylinder, a rotary oil cylinder, and the like.

[0063] Specifically, the wind shield 50 is connected to the third connecting rod 304 or the panel 20. The wind shield 50 can be slidably connected to the third connecting rod 304 or the panel 20, or rotatably connected, so that the wind shield 50 has a certain degree of freedom to move to achieve the effect of intercepting airflow.

[0064] Reference Figure 5 As shown, in some embodiments, the windshield 50 is rotatably connected to the third connecting rod 304 or the panel 20. By setting the windshield 50 to be rotatably connected to the third connecting rod 304 or the panel 20, the movement trajectory of the windshield 50 is the same each time, making the movement of the windshield 50 more stable and improving reliability.

[0065] In the above solution, the wind shield 50 and the housing 10 can be connected by rotation or by sliding.

[0066] Reference Fig. 9 , Fig.10 As shown, in some embodiments, one of the windshield 50 and the third connecting rod 304 is provided with a sliding portion 602, and the other is provided with a sliding groove 601, and the sliding portion 602 is arranged in the sliding groove 601. Through the cooperation between the sliding portion 602 and the sliding groove 601, the sliding portion 602 slides in the sliding groove 601, thereby increasing the range of movement of the windshield 50 and reducing the probability of the windshield 50 being stuck.

[0067] For example, a sliding portion 602 is provided on the wind shield 50, a sliding groove 601 is provided on the third connecting rod 304, and the sliding portion 602 is provided in the sliding groove 601; or, a sliding portion 602 is provided on the third connecting rod 304, a sliding groove 601 is provided on the wind shield 50, and the sliding portion 602 is provided in the sliding groove 601.

[0068] In some specific embodiments, the sliding portion 602 is configured as a sliding column, which is inserted into the sliding groove 601 and slidingly matched with the sliding groove 601 .

[0069] In some embodiments, the wind shield 50 is rotatably connected to the housing 10. By arranging that the wind shield 50 is rotatably connected to the housing 10, the movement track of the wind shield 50 is the same each time, so that the movement of the wind shield 50 is more stable and the reliability is improved.

[0070] Reference Figure 6 As shown, in some embodiments, a receiving groove 10c is provided on one side of the housing 10 close to the panel 20, and the windshield 50 is provided in the receiving groove 10c, and the rotating shaft 504 of the windshield 50 is close to the bottom wall of the receiving groove 10c. The receiving groove 10c can accommodate the windshield 50 and prevent the windshield 50 from protruding from the housing 10, which is conducive to keeping the surface of the housing 10 flat, facilitating the installation of the panel 20, and also making the structure of the air conditioner indoor unit 100 more compact.

[0071] Secondly, in the related art, a gap is easily present between the end of the wind shield member near the rotating shaft and the casing. In the embodiment of the utility model, the rotating shaft 504 is arranged near the bottom wall of the accommodating groove 10c, and the gap between the wind shield member 50 and the casing 10 is hidden at the groove wall of the accommodating groove 10c. This can increase the difficulty of wind entering the gap between the wind shield member 50 and the casing 10, and further reduce the probability of wind flowing out of the gap between the wind shield member 50 and the casing 10.

[0072] Reference Figure 5 As shown, in some embodiments, a display component 21 is provided on a side of the panel 20 close to the housing 10 , and a wind shield 50 is provided between the display component 21 and the housing 10 .

[0073] In the above scheme, a display component 21 is provided on one side of the panel 20 close to the casing 10. The display component 21 has a display effect. The display component 21 is set on the panel 20 and moves with the panel 20, so that the user can always observe the display component 21, which is convenient for the user's operation.

[0074] In some specific embodiments, referring to Fig.11 As shown, a display avoidance opening 51 is provided on the wind shield 50 to avoid the display component 21 .

[0075] In some specific embodiments, the first wind dispersion area 20a includes a plurality of first wind dispersion holes, wherein a portion of the first wind dispersion holes is disposed opposite to the display component 21, and another portion of the first wind dispersion holes is disposed around the display component 21. By arranging a portion of the first wind dispersion holes to be disposed opposite to the display component 21, and another portion of the first wind dispersion holes to be disposed around the display component 21, the first wind dispersion holes on the panel 20 are arranged in order, and the appearance of the panel 20 is more orderly and more beautiful.

[0076] In some specific embodiments, a display placement groove is provided on the side of the panel 20 facing the housing 10, the opening of the display placement groove is flush with the side of the panel 20 and extends in a direction away from the housing 10, and the display component 21 is provided in the display placement groove. The display placement groove is provided to install the display component 21, and the structure of the display placement groove reduces the thickness of the panel 20, so that the display component 21 can be displayed through the panel 20.

[0077] Reference Figures 6 to 8 As shown, in some embodiments, the windshield 50 includes a base portion 501 and a heat preservation portion 502, the base portion 501 is connected to the housing 10, and the heat preservation portion 502 is disposed on the base portion 501. By arranging the heat preservation portion 502 on the base portion 501, the heat preservation portion 502 has a heat insulation effect, reduces the probability of condensation forming on the baffle member, reduces the probability of dripping risk, and makes the windshield 50 have a better anti-condensation effect.

[0078] In the related art, when the air-conditioning indoor mechanism is cooling or heating, the temperature difference on both sides of the wind shield is large. The embodiment of the utility model is provided with a heat preservation part 502, which can play a role of heat insulation and heat preservation, reduce the heat transfer on the wind shield 50, and can reduce the probability of condensation forming on the surface of the base part 501, reduce the probability of dripping risk, and make the wind shield 50 have better anti-condensation effect.

[0080] The base portion 501 may be a flat plate-shaped component, which mainly serves to block the wind guide space 70 .

[0081] The heat-insulating part 502 may be a heat-insulating material to play a role in heat insulation. The heat-insulating part 502 may be, but is not limited to, a flannel, a glass wool material, a rock wool material, a polystyrene material, etc. Figure 6 The heat-insulating portion 502 and the base portion 501 may be arranged in upper and lower layers along the thickness direction of the wind shield 50 .

[0082] When the indoor unit 100 of the air conditioner is heating or cooling, the temperature difference between the air outlet 10a and the air inlet 10b is large, and the wind in the air guide space 70 comes from the air outlet 10a. The wind shield 50 is located in the air guide space 70. Figure 5 and Figure 6The temperature on the middle and upper sides) is relatively high. By configuring the wind shield 50 to include a base portion 501 and a heat-insulating portion 502, the heat-insulating portion 502 can play a role in heat insulation and reduce heat transfer on the base portion 501. This can reduce the probability of condensation forming on the surface of the base portion 501 and the probability of dripping risk, thereby making the wind shield 50 have a better anti-condensation effect.

[0083] In some embodiments of the present invention, Figures 6 to 8 As shown, the wind shield 50 further includes a sealing portion 503 , which is disposed on the base portion 501 and close to the panel 20 . When the driving mechanism 30 drives the panel 20 away from the housing 10 , the sealing portion 503 can stop against the panel 20 .

[0084] The sealing part 503 may refer to a component that can play a sealing role. The sealing part 503 can play a sealing role between the panel 20 and the base part 501, reduce the probability of a gap between the panel 20 and the base part 501, prevent the wind in the wind guide space 70 from leaking to the side close to the air inlet 10b, further reduce the probability of condensation on the surface of the base part 501, and help improve the anti-condensation effect and the anti-backflow effect.

[0085] In some embodiments of the present invention, the sealing portion 503 may be, but is not limited to, a rubber sealing strip and a soft brush member.

[0086] Specifically, the sealing portion 503 may extend along the length direction of the base portion 501. For example, the base portion 501 is a long strip plate, and the sealing portion 503 is a long strip sealing strip.

[0087] In some embodiments of the present invention, Figures 6 to 8 As shown, the base portion 501 includes a shell 5011 and a cover plate 5012, the shell 5011 is provided with a third opening 5011a; the cover plate 5012 is covered on the third opening 5011a, so that the cover plate 5012 and the shell 5011 enclose a cavity 501a, and the heat preservation portion 502 is provided in the cavity 501a.

[0088] It can be understood that the base 501 forms a shell structure, and the heat-insulating part 502 can be arranged in the cavity 501a formed by the cover plate 5012 and the shell 5011, so that the heat-insulating part 502 is installed on the base 501 more simply and more firmly, and is not easy to be separated. Moreover, the heat-insulating part 502 can be easily replaced by simply disassembling the shell 5011 and the cover plate 5012, which is conducive to the maintenance of the heat-insulating part 502. The windshield member 50 using the above solution has a simple structure and can reduce costs.

[0089] In some embodiments of the present invention, Figure 7 and Figure 8As shown, the third opening 5011a is arranged in the thickness direction of the housing 5011. In this way, the third opening 5011a is relatively large, and the cover plate 5012 is also relatively large, which can be a rectangular plate. In this technical solution, the larger third opening 5011a can make it easier to install or remove the heat preservation part 502.

[0090] In some embodiments of the present invention, Figures 6 to 8 As shown, the cover plate 5012 is provided with a first clamping portion 50121 , and the housing 5011 is provided with a second clamping portion 50111 , and the second clamping portion 50111 is connected to the first clamping portion 50121 by clamping.

[0091] One of the first clamping portion 50121 and the second clamping portion 50111 may be a hook, and the other may be a slot, or both of the first clamping portion 50121 and the second clamping portion 50111 may be hooks (see Figure 7 and Figure 8 ).

[0092] In the above technical solution, the cover plate 5012 and the housing 5011 are detachably connected through the second clamping portion 50111 and the first clamping portion 50121. The disassembly structure is simple, the cost can be reduced, and the installation or disassembly is also convenient.

[0093] In some embodiments of the present invention, the heat-insulating portion 502 may cover the surface of the base portion 501. It can be understood that the heat-insulating portion 502 and the base portion 501 form a double-layer structure, which is relatively simple and can reduce manufacturing costs.

[0094] In some embodiments of the present invention, Figure 6 As shown, the cover plate 5012 and the housing 5011 enclose a mounting groove 501b, and part of the sealing portion 503 is disposed in the mounting groove 501b.

[0095] At least one of the cover plate 5012 and the housing 5011 may be provided with a groove, and when the cover plate 5012 and the housing 5011 are connected, they enclose the installation groove 501b. For example, the cover plate 5012 is provided with a groove, and when the cover plate 5012 is covered on the housing 5011, the groove and the housing 5011 define the installation groove 501b. Alternatively, the housing 5011 is provided with a groove, and when the cover plate 5012 is covered on the housing 5011, the groove and the cover plate 5012 define the installation groove 501b. Alternatively, refer to Figure 7 and Figure 8 The cover plate 5012 is provided with a first groove 5012a, and the housing 5011 is provided with a second groove 5011b. When the cover plate 5012 is covered on the housing 5011, the first groove 5012a and the second groove 5011b jointly define a mounting groove 501b.

[0096] In the above scheme, the sealing part 503 can be partially installed on the cover plate 5012 or the outer shell 5011 first. When the cover plate 5012 and the outer shell 5011 are connected, the sealing part 503 can be clamped in the installation groove 501b, so that the installation structure of the sealing part 503 and the base part 501 is relatively simple, which is conducive to reducing costs. Moreover, the installation of the sealing part 503 and the base part 501 in this way is also relatively reliable and not easy to loosen.

[0097] In some embodiments of the present invention, Figure 6 As shown, in the thickness direction of the wind shield 50, the slot size of the mounting slot 501b is smaller than the maximum size of the mounting slot 501b, the sealing portion 503 includes a first portion 5031 and a second portion 5032 connected to each other, in the thickness direction of the wind shield 50, the thickness of the first portion 5031 is greater than the thickness of the second portion 5032, and the first portion 5031 is arranged in the mounting slot 501b.

[0098] In this technical solution, when the first part 5031 is arranged in the installation groove 501b, the first part 5031 can fill the space in the installation groove 501b. Therefore, the size of the first part 5031 is larger than the slot size of the installation groove 501b. The first part 5031 is not easy to separate from the slot of the installation groove 501b, which can improve the connection reliability between the sealing part 503 and the wind shield 50.

[0099] Optionally, the cross-section of the mounting groove 501 b and the first portion 5031 may be, but not limited to, circular, rectangular, and the like.

[0100] In some embodiments of the present invention, Figures 6 to 8 As shown, a rotating shaft 504 is provided at one end of the wind shield 50 close to the housing 10 , and the rotating shaft 504 is rotatably disposed on the housing 10 .

[0101] It can be understood that the wind shield 50 can move to the target position by rotating, thereby blocking the wind guide space 70. When the air-conditioning indoor unit 100 is in the closed mode, the wind shield 50 can be close to the shell wall of the casing 10. When the air-conditioning indoor unit 100 is in the windless mode, the wind shield 50 can rotate driven by the rotating shaft 504. The other end of the wind shield 50 away from the rotating shaft 504 stops at the panel 20, blocking the wind guide space 70.

[0102] In the above technical solution, the wind shield 50 realizes position switching by rotation, and the structure is relatively simple. The wind shield 50 can be set on the outside of the casing 10 and does not occupy the internal space of the casing 10, which is conducive to reducing the complexity of the structure.

[0103] In some embodiments of the present invention, Figure 7 and Figure 8As shown, the windshield 50 is provided with a plurality of rotating shafts 504, and the plurality of rotating shafts 504 are arranged at intervals along the length direction of the windshield 50. Since the length of the air outlet channel 10a is generally long, the length of the windshield 50 is also long. On this basis, the windshield 50 is rotatably connected to the housing 10 through the plurality of rotating shafts 504, which can improve the connection reliability and reduce the probability of a large gap between the windshield 50 and the housing 10 after long-term use, thereby reducing the probability of wind flowing through the gap between the windshield 50 and the housing 10.

[0104] Optionally, the number of the rotating shafts 504 may be, but is not limited to, two, three, four, five, etc.

[0105] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the housing 5011 is provided with one or more first opening slots 5011c, and the first opening slots 5011c are each provided with a rotating shaft 504. The first opening slots 5011c can accommodate the rotating shaft 504. The housing 5011 is provided with the first opening slots 5011c to accommodate the rotating shaft 504, which is beneficial to reducing the gap between the housing 5011 and the housing 10, and reducing the probability of wind flowing out of the gap between the housing 5011 and the housing 10.

[0106] Optionally, when the shell 5011 is provided with a plurality of first opening grooves 5011 c , the plurality of first opening grooves 5011 c are arranged at intervals along the length direction of the shell 5011 .

[0107] Alternatively, if Figure 7 and Figure 8 As shown, the two ends of the shell 5011 in the length direction are provided with shafts 504. It can be understood that the two ends of the shell 5011 in the length direction and the middle area of ​​the shell 5011 can be connected to the housing 10 through the shafts 504, which can improve the connection reliability between the shell 5011 and the housing 10 and reduce the large gap between the shell 5011 and the housing 10 after long-term rotation.

[0108] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the cover plate 5012 is provided with second opening slots 5012b, and the number of the second opening slots 5012b and the first opening slots 5011c are equal and correspond to each other. Since the cover plate 5012 is covered on the housing 5011, the shaft 504 can be observed through the second opening slots 5012b, which facilitates the installation or removal of the shaft 504 and the housing 10.

[0109] In some embodiments of the present invention, Figure 7 and Figure 8As shown, the heat preservation part 502 is provided with avoidance grooves 502a, and the number of avoidance grooves 502a and the first opening grooves 5011c are equal and correspond to each other. It can be understood that, since the heat preservation part 502 is arranged in the shell 5011, the avoidance grooves 502a are arranged in the heat preservation part 502, and the avoidance grooves 502a can avoid the first opening grooves 5011c, which is conducive to arranging a larger heat preservation part 502 in the shell 5011, bringing better heat preservation effect.

[0110] In some embodiments of the present invention, Figure 6 As shown, when the air conditioner indoor unit 100 is in the windless mode, the wind shielding member 50 rotates to tilt toward a side away from the air outlet channel 10 a and stops at the panel 20 .

[0111] Since the wind shield 50 rotates at the rotating shaft 504, a gap is likely to exist between the end of the wind shield 50 close to the rotating shaft 504 and the casing 10. By tilting the wind shield 50, it can play a guiding role, guiding the wind in the wind guide space 70 to flow toward the panel 20, reducing the wind flowing toward the rotating shaft 504, and reducing the probability of wind flowing out of the gap between the wind shield 50 and the casing 10, thereby enhancing the effect of the wind shield 50 in blocking airflow, which is beneficial to further reduce the occurrence of backflow short circuit and condensation.

[0112] Reference Figure 3 to, Figure 4 and Figure 5 As shown, in some embodiments, the air conditioner indoor unit 100 further includes: an air guide 40, which is rotatably disposed on the air outlet channel 10a to guide the air flow direction, and the air guide 40 is provided with a second wind dispersion area 40a for dispersing the wind. Wherein, when the air conditioner indoor unit 100 is in the windless mode, the air guide 40 rotates to at least block a portion of the air outlet channel 10a so that the airflow flows through the second wind dispersion area 40a.

[0113] In the above solution, the second wind dispersing area 40a on the wind guide 40 is used to disperse the wind, so that the airflow discharged from the air outlet channel 10a disperses after passing through the second wind dispersing area 40a, forming an experience of no wind. For example, the second wind dispersing area 40a includes a plurality of second wind dispersing holes arranged at intervals, and the second wind dispersing holes with smaller apertures disperse the airflow to form an experience of no wind; or the second wind dispersing area 40a includes a second hole structure and a second wind dispersing fan arranged in the second hole structure, and the second wind dispersing fan disperses the airflow to form an experience of no wind.

[0114] The air conditioner indoor unit 100 has a windless mode. In the windless mode, the panel 20 moves to be spaced apart from the front side of the casing 10 to define an air guide space 70. The lower end of the air guide space 70 is connected to the air outlet channel 10a to guide the airflow to the first wind dispersion area 20a. The air guide member 40 rotates to at least block part of the air outlet channel 10a so that the airflow flows through the second wind dispersion area 40a.

[0115] That is to say, the airflow discharged from the air outlet channel 10a flows through at least the first wind dispersion area 20a and the second wind dispersion area 40a. Compared with the first wind dispersion area or the second wind dispersion area alone in the related art, the cooperation between the first wind dispersion area 20a and the second wind dispersion area 40a has a larger wind dispersion area, reduces wind resistance, and increases exhaust volume.

[0116] For example, the first wind dispersion area 20a includes 10 first wind dispersion holes, and the second wind dispersion area 40a includes 5 second wind dispersion holes. The related art only has 10 first wind dispersion holes or 5 second wind dispersion holes, while the utility model is provided with 10 first wind dispersion holes and 5 second wind dispersion holes, and the wind dispersion area is larger, which reduces wind resistance and increases exhaust volume.

[0117] Reference Figure 5 As shown, in some embodiments, in the windless mode, the front end of the air guide 40 cooperates with the lower end of the panel 20 to guide a portion of the airflow to the air guide space 70. The front end of the air guide 40 cooperates with the lower end of the panel 20 to guide the airflow to the air guide space 70, making full use of the large volume of the air guide space 70, so that more airflow flows into the air guide space 70, further improving the wind resistance problem.

[0118] Specifically, the front end of the air guide member 40 and the lower end of the panel 20, wherein the direction is based on the air conditioner indoor unit 100 installed on the vertical wall as a reference standard, the air conditioner indoor unit 100 is installed on the vertical wall, the direction of the air conditioner indoor unit 100 toward the vertical wall is the rear, the direction of the air conditioner indoor unit 100 facing the vertical wall is the front, the direction of the air conditioner indoor unit 100 facing the ceiling is the top, and the direction of the air conditioner indoor unit 100 facing away from the ceiling is the bottom.

[0119] Among them, the cooperation between the front end of the air guide member 40 and the lower end of the panel 20 can be an overlapping cooperation or an abutting cooperation, or there can be a small gap between the front end of the air guide member 40 and the lower end of the panel 20. The small gap between the front end of the air guide member 40 and the lower end of the panel 20 also plays the effect of diverging airflow.

[0120] In some embodiments, in the windless mode, one of the front end of the air guide 40 and the lower end of the panel 20 is located below the other.

[0121] For example, the front end of the air guide member 40 is located below the lower end of the panel 12, and there is a gap between the air guide member 40 and the panel 20, and the gap has the effect of dispersing the airflow; or, the lower end of the panel 20 is located below the air guide member 40, and the air guide member 40 and the panel 20 fully block the air outlet channel 10a.

[0122] Reference Figure 3 to, Figure 5As shown, in some embodiments, the air guide 40 is provided with a plurality of louvers 401, and the plurality of louvers 401 are arranged at intervals along the length direction of the air guide 40. By arranging a plurality of louvers 401 at intervals along the length direction of the air guide 40, the air flow direction is guided by the plurality of louvers 401, thereby improving the effect of the air conditioner indoor unit 100.

[0123] In some specific embodiments, a movable rod is provided between the plurality of louvers 401, and the movable rod drives the louvers 401 to swing, wherein the movable rod is integrally formed with the louvers 401. By providing the movable rod integrally formed with the louvers 401, the number of parts is reduced, the assembly is simplified, and the air guiding area of ​​the air guide member 40 is increased, thereby improving the air guiding effect.

[0124] Specifically, the louver 401 is suitable for elastic deformation, and the movement of the movable rod causes the louver 401 to undergo elastic deformation to change the air flow direction.

[0125] In some embodiments, a shutter movable part is provided on the housing 10, and the shutter movable part is connected to the movable rod to drive the movable rod to move. For example, the shutter movable part is a telescopic motor, and the telescopic motor drives the movable rod to telescope.

[0126] In some embodiments, the housing 10 is further provided with an air guide movable member, which is connected to the air guide member 40 to drive the air guide member 40 to rotate, wherein the air guide movable member and the shutter movable member are respectively located on two opposite inner walls of the air outlet channel 10a. By respectively arranging the air guide movable member and the shutter movable member on two opposite inner walls of the air outlet channel 10a, the two inner walls are fully utilized.

[0127] For example, the wind guide movable part is located on the left inner wall of the air outlet channel 10a, and the shutter movable part is located on the right inner wall of the air outlet channel 10a; or, the wind guide movable part is located on the right inner wall of the air outlet channel 10a, and the shutter movable part is located on the left inner wall of the air outlet channel 10a.

[0128] In some embodiments of the present invention, the housing 10 includes a chassis 101 and a face frame 102, the face frame 102 is disposed on the chassis 101, and the air outlet 10a and the air inlet 10b are disposed on the face frame 102. In this technical solution, the housing 10 adopts a split structure design, and the chassis 101 and the face frame 102 can be manufactured separately, which can reduce the difficulty of mold opening and reduce costs.

[0129] The air conditioner according to the embodiment of the present invention includes the air conditioner indoor unit 100 as described above.

[0130] like Figure 3 and Figure 5As shown, the air conditioner indoor unit 100 may further include a heat exchanger 80 and a wind wheel 90. When the air conditioner indoor unit 100 is working, air enters the air inlet 10b, and the air passes through the heat exchanger 80 for heat exchange. The air after heat exchange is driven to the air outlet channel 10a through the wind wheel 90, and then the air enters the air guide space 70, and slowly exits through the first wind dissipation area 20a of the panel 20, so as to achieve a windless effect. The heat exchanger 80 may be a condenser or an evaporator. When the heat exchanger 80 is a condenser, the passing wind can be converted into hot wind to achieve heating; when the heat exchanger 80 is a cold evaporator, the passing wind can be converted into cold wind to achieve cooling.

[0131] According to the air conditioner of the embodiment of the utility model, by setting the wind shield 50, the wind shield 50 can be moved to between the air outlet end of the wind guide space 70 and the air inlet 10b, that is, the wind shield 50 can play the role of intercepting the airflow, avoiding the airflow in the wind guide space 70 from flowing to the air inlet 10b, reducing the probability of backflow short circuit caused by the large temperature difference of the air at the air inlet 10b, and also avoiding the situation that the temperature detected by the temperature sensor at the air inlet 10b is inconsistent with the actual indoor temperature, reducing the situation of incorrect frequency modulation or shutdown of the air conditioner outdoor unit, so that the air conditioner indoor unit 100 has a better anti-backflow effect and higher working reliability. At the same time, the wind shield 50 is set to be linked with the driving mechanism 30 or the panel 20, the driving mechanism 30 drives both the wind shield 50 and the panel 20, and the wind shield 50 and the panel 20 are uniformly driven by the driving mechanism 30. With this solution, there is no need to set a separate driving component for the wind shield 50, thereby reducing the number of components and simplifying the control strategy while avoiding backflow.
