Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air guide plate structure, an air conditioner indoor unit and an air conditioner. Background Art

[0002] At present, in addition to the basic functions of cooling and heating, the comfort of air supply is also receiving more and more attention. Whether in the process of cooling or heating, if the cold / hot air flow is blowing towards people all the time, it can easily cause discomfort to the human body. The elderly and children with slightly poor physical fitness may even suffer from air-conditioning disease.

[0003] Existing air conditioner products usually have an air guide assembly (the air guide assembly includes an air guide plate and a wind sweeping blade) disposed at the air outlet to adjust the air outlet direction of the air conditioner.

[0004] However, the existing air guide plate structure is usually an air guide plate, and the air outlet direction of the air conditioner is adjusted by flipping the air guide plate. The air outlet method that can be achieved by this air guide plate structure is relatively simple, resulting in poor air supply comfort of the air conditioner.

[0005] Alternatively, the existing air guide plate structure is a multi-layer air guide plate, but this air guide plate structure will cause a large attenuation of air volume, and the cold air will sink prematurely and other adverse effects. Summary of the invention

[0006] The main purpose of the present invention is to provide an air guide plate structure, an air conditioner indoor unit and an air conditioner to solve the problem that the air outlet mode of the air guide plate structure of the air conditioner in the prior art is relatively single.

[0007] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, there is provided an air guide plate structure, which is used to be arranged at the outlet end of an air outlet channel and comprises a first air guide plate, a second air guide plate, and a third air guide plate which are arranged in sequence; wherein, an end of the first air guide plate away from the second air guide plate is a free end which can be opened and closed; when the first air guide plate is in an open state, at least a part of the first air guide plate is inclined upward; an end of the second air guide plate away from the first air guide plate is a free end which can be opened and closed, and an end of the third air guide plate close to the second air guide plate is a free end which can be opened and closed; the second air guide plate and the third air guide plate are both located at the lower part of the air outlet channel; when the second air guide plate and the third air guide plate are both in a closed state, the free end of the second air guide plate contacts the free end of the third air guide plate.

[0008] Furthermore, the air guide plate structure includes: a fourth air guide plate, which is rotatably arranged in the air outlet channel so that the fourth air guide plate has an avoidance state in which it is in contact with the inner wall of the air outlet channel and a stop state in which it is arranged at an angle to the inner wall surface of the air outlet channel; along the distribution direction of the first air guide plate and the second air guide plate, the fourth air guide plate is located at the connecting end of the second air guide plate or at the side of the second air guide plate close to the first air guide plate; wherein, the end of the second air guide plate close to the first air guide plate is its connecting end.

[0009] Furthermore, the rotation axis of the fourth air guide plate is parallel to the rotation axis of the second air guide plate, and along the direction perpendicular to the rotation axis of the fourth air guide plate, the two ends of the fourth air guide plate are respectively a connecting end and a free end; when the fourth air guide plate is in an avoidance state or when the second air guide plate is in a closed state, the free end of the fourth air guide plate is spaced apart from the free end of the second air guide plate; when the fourth air guide plate is in a stop state and the second air guide plate is opened toward the inner side of the air outlet channel, the free end of the fourth air guide plate can contact the free end of the second air guide plate.

[0010] Further, when the second air guide plate is in a closed state, the second air guide plate is parallel to the extension direction of the air outlet channel; and / or, when the third air guide plate is in a closed state, the third air guide plate is parallel to the extension direction of the air outlet channel.

[0011] Furthermore, when the air outlet channel is used to discharge cold air, the first air guide plate is opened to allow at least part of the airflow in the air outlet channel to flow out obliquely upward; when the air outlet channel is used to discharge hot air, the first air guide plate is closed.

[0012] Further, when the air outlet channel is used to discharge cold air, the fourth air guide plate is in a avoiding state; when the air outlet channel is used to discharge hot air, the fourth air guide plate is in a stopping state.

[0013] Furthermore, when the air outlet channel is used to discharge cold air, the air guide plate structure has three air outlet modes; when the air guide plate structure is in the first air outlet mode, the second air guide plate and the third air guide plate are both in a closed state; when the air guide plate structure is in the second air outlet mode, the second air guide plate and the third air guide plate are both open toward the outside of the air outlet channel; when the air guide plate structure is in the third air outlet mode, the second air guide plate is open toward the inside of the air outlet channel, and the third air guide plate is open toward the outside of the air outlet channel.

[0014] Furthermore, when the second air guide plate is in a closed state, the second air guide plate is in an initial position parallel to the extension direction of the air outlet channel; when the air guide plate structure is the third air outlet mode, the second air guide plate rotates from its initial position to a predetermined angle, and the predetermined angle is an acute angle or 90 degrees.

[0015] Furthermore, when the air outlet channel is used to discharge hot air, the air guide plate structure has three air outlet forms; when the air guide plate structure is the first air outlet form, the second air guide plate and the third air guide plate are both opened toward the inside of the air outlet channel; when the air guide plate structure is the second air outlet form, the second air guide plate and the third air guide plate are both opened toward the outside of the air outlet channel; when the air guide plate structure is the third air outlet form, the second air guide plate is opened toward the inside of the air outlet channel, and the third air guide plate is opened toward the outside of the air outlet channel.

[0016] According to another aspect of the present invention, an air conditioner indoor unit is provided, which comprises a casing and the above-mentioned air guide plate structure, wherein the casing forms an air outlet channel.

[0017] According to another aspect of the present invention, there is provided an air conditioner, comprising the above-mentioned air conditioner indoor unit.

[0018] Applying the technical solution of the present invention, in the air guide plate structure of the present invention, the air guide plate structure is used to be arranged at the outlet end of the air outlet channel and includes a first air guide plate, a second air guide plate, and a third air guide plate which are arranged in sequence; wherein, an end of the first air guide plate away from the second air guide plate is a free end which can be opened and closed; when the first air guide plate is in an open state, at least a part of the first air guide plate is inclined upward; an end of the second air guide plate away from the first air guide plate is a free end which can be opened and closed, and an end of the third air guide plate close to the second air guide plate is a free end which can be opened and closed; the second air guide plate and the third air guide plate are both located at the lower part of the air outlet channel; when the second air guide plate and the third air guide plate are both in a closed state, the free end of the second air guide plate contacts the free end of the third air guide plate.

[0019] By opening the first air guide plate, an air outlet, namely the first air outlet, can be formed at the free end of the first air guide plate; when the first air guide plate is in an open state, at least a portion of the first air guide plate is tilted upward so that the airflow passing through the first air guide plate flows out tilted upward along the inner wall of the first air guide plate, thereby achieving the wind blown out from the first air outlet to be blown out tilted upward; by opening the second air guide plate and / or the third air guide plate, another air outlet, namely the second air outlet, can be formed between the second air guide plate and the third air guide plate; the second air guide plate and the third air guide plate are both located at the lower part of the air outlet channel, so that the wind blown out from the second air outlet is sent downward; when the second air guide plate and the third air guide plate are both closed, the free end of the second air guide plate contacts the free end of the third air guide plate, i.e. the second air outlet is closed.

[0020] Furthermore, the structural arrangement of the first air guide plate of the present application limits the first air guide plate to be opened only toward the outside of the air outlet channel, while the structural arrangement of the second air guide plate and the third air guide plate of the present application can realize that the second air guide plate is opened toward the inside or outside of the air outlet channel, and can also realize that the third air guide plate is opened toward the inside or outside of the air outlet channel; when the second air guide plate and / or the third air guide plate are opened toward the outside of the air outlet channel, the second air guide plate and / or the third air guide plate can guide and divert the wind blown out from the second air outlet; when the second air guide plate is opened toward the inside of the air outlet channel, the airflow flowing to the first air guide plate can be guided to a certain extent. The third air guide plate will block the air flow in the air outlet channel to a certain extent, so as to reduce the air flow toward the first air guide plate, thereby reducing the instantaneous air output of the first air outlet; when the third air guide plate is opened toward the inside of the air outlet channel until it is in contact with the inner wall of the air outlet channel, the third air guide plate will not affect the gas flow in the air outlet channel; when the third air guide plate is opened toward the inside of the air outlet channel and the third air guide plate is set at an angle to the inner wall of the air outlet channel, the third air guide plate will block the air flow in the air outlet channel to a certain extent, so that the air flow toward the second air guide plate and the first air guide plate is reduced, thereby reducing the instantaneous air output of the first air outlet and the second air outlet.

[0021] It can be seen that by rotating at least one of the three air guide plates, the air guide plate structure can form a variety of air outlet modes. During specific use, at least one of the three air guide plates can be rotated according to actual needs to adjust the appropriate air outlet mode and improve the air supply comfort. The use of this air guide plate structure can solve the problem of the relatively single air outlet mode of the air guide plate structure of the air conditioner in the prior art.

[0043] The present invention provides a wind deflector structure, please refer to Figures 1 to 15 The air guide plate structure is used to be arranged at the outlet end of the air outlet channel 51 and includes a first air guide plate 10, a second air guide plate 20, and a third air guide plate 30 arranged in sequence; wherein, the end of the first air guide plate 10 away from the second air guide plate 20 is a free end that can be opened and closed, that is, the end of the first air guide plate 10 away from the second air guide plate 20 is rotatably arranged to open or close the first air guide plate 10; when the first air guide plate 10 is in an open state, at least a portion of the first air guide plate 10 is tilted upward; the end of the second air guide plate 20 away from the first air guide plate 10 is a free end that can be opened and closed , that is, the end of the second air guide plate 20 away from the first air guide plate 10 is rotatably arranged to open or close the second air guide plate 20; the end of the third air guide plate 30 close to the second air guide plate 20 is a free end that can be opened and closed, that is, the end of the third air guide plate 30 close to the second air guide plate 20 is rotatably arranged to open or close the third air guide plate 30; the second air guide plate 20 and the third air guide plate 30 are both located at the lower part of the air outlet channel 51; when the second air guide plate 20 and the third air guide plate 30 are both in a closed state, the free end of the second air guide plate 20 contacts the free end of the third air guide plate 30.

[0044] In the wind guide plate structure of the present invention, by opening the first wind guide plate 10, an air outlet, namely the first air outlet, can be formed at the free end of the first wind guide plate 10; when the first wind guide plate 10 is in the open state, at least a portion of the first wind guide plate 10 is arranged to be tilted upward, so that the airflow passing through the first wind guide plate 10 flows out tilted upward along the inner wall of the first wind guide plate 10, thereby realizing that the wind blown out from the first air outlet is blown out tilted upward; by opening the second wind guide plate 20 and / or the third wind guide plate 30, another air outlet, namely the second air outlet, can be formed between the second wind guide plate 20 and the third wind guide plate 30; the second wind guide plate 20 and the third wind guide plate 30 are both located at the lower part of the air outlet channel 51, so that the wind blown out from the second air outlet is sent downward; when the second wind guide plate 20 and the third wind guide plate 30 are both closed, the free end of the second wind guide plate 20 contacts the free end of the third wind guide plate 30, i.e. the second air outlet is closed.

[0045] Furthermore, the structural setting of the first air guide plate 10 of the present application limits the first air guide plate 10 to be able to rotate (open) only toward the outside of the air outlet channel 51, while the structural setting of the second air guide plate 20 and the third air guide plate 30 of the present application can realize the second air guide plate 20 to rotate (open) toward the inside or outside of the air outlet channel 51, and can also realize the third air guide plate 30 to rotate (open) toward the inside or outside of the air outlet channel 51; when the second air guide plate 20 and / or the third air guide plate 30 are opened toward the outside of the air outlet channel 51, the second air guide plate 20 and / or the third air guide plate 30 can guide and drain the wind blown out from the second air outlet; when the second air guide plate 20 is opened toward the inside of the air outlet channel 51, the wind flowing toward the first air guide plate 1 0 is stopped to a certain extent, so as to reduce the size of the airflow flowing to the first air guide plate 10, thereby reducing the instantaneous air volume of the first air outlet; when the third air guide plate 30 is opened toward the inner side of the air outlet channel 51 until it is in contact with the inner wall of the air outlet channel 51, the third air guide plate 30 will not affect the gas flow in the air outlet channel 51; when the third air guide plate 30 is opened toward the inner side of the air outlet channel 51 and the third air guide plate 30 is set at an angle to the inner wall of the air outlet channel 51, the third air guide plate 30 will stop the airflow in the air outlet channel 51 to a certain extent, so that the airflow flowing to the second air guide plate 20 and the first air guide plate 10 is reduced, thereby reducing the instantaneous air volume of the first air outlet and the second air outlet.

[0046] It can be seen that by rotating at least one of the three air guide plates (the first air guide plate 10, the second air guide plate 20, and the third air guide plate 30), the air guide plate structure can form a variety of air outlet modes. During specific use, at least one of the three air guide plates can be rotated according to actual needs to adjust a suitable air outlet mode and improve the air supply comfort. The use of this air guide plate structure can solve the problem that the air outlet mode of the air guide plate structure of the air conditioner in the prior art is relatively single.

[0047] In addition, the air guide plate structure can not only realize a variety of air outlet modes, but also will not cause the problem of air volume attenuation, and also avoids the problem of cold air sinking prematurely.

[0048] It should be noted that along the distribution direction of the first air guide plate 10, the second air guide plate 20, and the third air guide plate 30, the first air guide plate 10 has a first end and a second end that are relatively arranged. The first end of the first air guide plate 10 is the end away from the second air guide plate 20, that is, the free end; the second end of the first air guide plate 10 is the end close to the second air guide plate 20, that is, the connecting end.

[0049] It should be noted that along the distribution direction of the first air guide plate 10, the second air guide plate 20, and the third air guide plate 30, the second air guide plate 20 has a first end and a second end that are relatively arranged. The first end of the second air guide plate 20 is the end close to the first air guide plate 10, that is, the connecting end; the second end of the second air guide plate 20 is the end away from the first air guide plate 10, that is, the free end.

[0050] It should be noted that along the distribution direction of the first air guide plate 10, the second air guide plate 20, and the third air guide plate 30, the third air guide plate 30 has a first end and a second end that are relatively set. The first end of the third air guide plate 30 is the end close to the second air guide plate 20, that is, the free end; the second end of the third air guide plate 30 is the end away from the second air guide plate 20, that is, the connecting end.

[0051] It should be noted that the rotation axis of the first air guide plate 10 is parallel to the plate surface of the first air guide plate 10 or is located on the plate surface of the first air guide plate 10, the rotation axis of the second air guide plate 20 is parallel to the plate surface of the second air guide plate 20 or is located on the plate surface of the second air guide plate 20, and the rotation axis of the third air guide plate 30 is parallel to the plate surface of the third air guide plate 30 or is located on the plate surface of the third air guide plate 30; the rotation axis of the first air guide plate 10 is parallel to or coincides with the rotation axis of the second air guide plate 20; the rotation axis of the third air guide plate 30 is parallel to the rotation axis of the second air guide plate 20.

[0052] Specifically, when the first air guide plate 10 is in the open state, the plate body portion of the first air guide plate 10 close to the free end thereof is disposed tilted upward.

[0053] It should be noted that, according to the arrangement of the three air guide plates of the present application, it can be known that the channel section of the air outlet channel 51 close to its outlet end is arranged in a horizontal direction, or inclined upward, or inclined downward; the plate body portion of the first air guide plate 10 close to its free end is arranged inclined upward and is located on the upper side of the second air guide plate 20, and the first air guide plate 10 is arranged at the outlet end of the air outlet channel 51.

[0054] Specifically, the air guide plate structure also includes a first rotating shaft 61, the connecting end of the first air guide plate 10 is connected to the first rotating shaft 61, and the first air guide plate 10 is rotatably arranged around the central axis of the first rotating shaft 61; the connecting end of the second air guide plate 20 is connected to the first rotating shaft 61, and the second air guide plate 20 is rotatably arranged around the central axis of the first rotating shaft 61.

[0055] Specifically, the air guide plate structure further includes a second rotating shaft 62 , a connecting end of the third air guide plate 30 is connected to the second rotating shaft 62 , and the third air guide plate 30 is rotatably disposed around a central axis of the second rotating shaft 62 .

[0056] Specifically, the free end of the first air guide plate 10 is located outside the air outlet channel 51 .

[0057] Specifically, the plate surface of the first air guide plate 10 is a curved surface.

[0058] In this embodiment, the air guide plate structure includes a fourth air guide plate 40, which is rotatably arranged in the air outlet channel 51, so that the fourth air guide plate 40 has a avoiding state of being in contact with the inner wall of the air outlet channel 51 and a stopping state of being arranged at an angle with the inner wall surface of the air outlet channel 51; a first arrangement mode of the fourth air guide plate 40 is: along the distribution direction of the first air guide plate 10 and the second air guide plate 20, the fourth air guide plate 40 is located at the connecting end of the second air guide plate 20; a second arrangement mode of the fourth air guide plate 40 is: along the distribution direction of the first air guide plate 10 and the second air guide plate 20, the fourth air guide plate 40 is located on the side of the second air guide plate 20 close to the first air guide plate 10. When the fourth air guide plate 40 is in the stopping state, the airflow flowing to the first air guide plate 10 in the air outlet channel 51 will be stopped to a certain extent, so as to reduce the size of the airflow flowing to the first air guide plate 10, thereby reducing the instantaneous air volume of the first air outlet.

[0059] It should be noted that the rotation axis of the fourth air guide plate 40 is parallel to the plate surface of the fourth air guide plate 40 or is located on the plate surface of the fourth air guide plate 40, and the rotation axis of the fourth air guide plate 40 is parallel to the rotation axis of the second air guide plate 20; along the direction perpendicular to the rotation axis of the fourth air guide plate 40, the two ends of the fourth air guide plate 40 are respectively a connecting end and a free end, and the free end of the fourth air guide plate 40 is rotatably arranged.

[0060] When the fourth air guide plate 40 is in the avoidance state, the distribution direction of the connection end and the free end of the fourth air guide plate 40 is parallel to the extension direction of the air outlet channel 51 .

[0061] Specifically, the air guide plate structure further includes a third rotating shaft 63 , a connecting end of the fourth air guide plate 40 is connected to the third rotating shaft 63 , and the fourth air guide plate 40 is rotatably disposed around a central axis of the third rotating shaft 63 .

[0062] In this embodiment, when the fourth air guide plate 40 is in the avoidance state or when the second air guide plate 20 is in the closed state, the free end of the fourth air guide plate 40 is spaced apart from the free end of the second air guide plate 20, and at this time the air flow in the air outlet channel 51 can flow to the first air guide plate 10; when the fourth air guide plate 40 is in the stopping state and the second air guide plate 20 is opened toward the inner side of the air outlet channel 51, the free end of the fourth air guide plate 40 can be in contact with the free end of the second air guide plate 20, and at this time the second air guide plate 20 and the fourth air guide plate 40 completely stop the air flow in the air outlet channel 51, and the air flow in the air outlet channel 51 cannot flow to the first air guide plate 10.

[0063] In this embodiment, when the second air guide plate 20 is in a closed state, the second air guide plate 20 is parallel to the extension direction of the air outlet channel 51. Since the second air guide plate 20 is arranged at the outlet end of the air outlet channel 51, the second air guide plate 20 is parallel to the extension direction of the channel section of the air outlet channel 51 close to its outlet end; in this way, when the second air guide plate 20 is closed and the first air guide plate 10 is opened, the second air guide plate 20 will not block the airflow in the air outlet channel 51, that is, it will not affect the airflow flowing to the first air guide plate 10.

[0064] It should be noted that, according to the structural arrangement of the fourth air guide plate 40 of the present application, the fourth air guide plate 40 is located on the upper side of the second air guide plate 20 .

[0065] When the third air guide plate 30 is in a closed state, the third air guide plate 30 is parallel to an extension direction of the air outlet channel 51. Since the third air guide plate 30 is arranged at the outlet end of the air outlet channel 51, the third air guide plate 30 is parallel to an extension direction of a channel section of the air outlet channel 51 close to its outlet end. In this way, when the third air guide plate 30 is closed and the first air guide plate 10 is opened, the third air guide plate 30 will not block the airflow in the air outlet channel 51, that is, it will not affect the airflow flowing to the first air guide plate 10.

[0066] In this embodiment, when the air outlet channel 51 is used to discharge cold air, that is, when the indoor unit of the air conditioner or the air conditioner using the air guide plate structure is in cooling mode, the air guide plate structure has three air outlet modes, which are as follows:

[0067] Specifically, Figures 2 to 9 As shown, when the air guide plate structure is in any air outlet mode, the first air guide plate 10 is opened to allow at least part of the airflow in the air outlet channel 51 to flow out obliquely upward, that is, the cold air delivered from the first air outlet flows out obliquely upward; since the density of the cold air is relatively large, the oblique upward air outlet mode is adopted to avoid the problem of a large amount of cold air accumulating on the ground.

[0068] Specifically, Figures 2 to 5As shown, when the air guide plate structure is in any air outlet mode, the fourth air guide plate 40 is in an avoidance state, that is, the fourth air guide plate 40 will not stop the cold air flowing to the first air guide plate 10 to ensure that a large amount of cold air is delivered from the first air outlet.

[0069] Specifically, Figure 2 and Figure 6 As shown, when the air guide plate structure is in the first air outlet mode, the second air guide plate 20 and the third air guide plate 30 are both in a closed state; at this time, the second air outlet is closed, and only cold air is delivered from the first air outlet to achieve a cooling air outlet effect.

[0070] Specifically, Figure 3 and Figure 7 As shown, when the air guide plate structure is in the second air outlet mode, the second air guide plate 20 and the third air guide plate 30 are both opened toward the outside of the air outlet channel 51. At this time, the first air outlet and the second air outlet are both opened to achieve simultaneous delivery of cold air from top to bottom.

[0071] Optionally, when the air guide plate structure is in the second air outlet mode, the second air guide plate 20 and the third air guide plate 30 are parallel.

[0072] Specifically, Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, when the air guide plate structure is in the third air outlet mode, the second air guide plate 20 is opened toward the inner side of the air outlet channel 51, and the third air guide plate 30 is opened toward the outer side of the air outlet channel 51; at this time, both the first air outlet and the second air outlet are opened, but because the second air guide plate 20 is opened toward the inner side of the air outlet channel 51, the cold air flow in the air outlet channel 51 to the first air guide plate 10 is reduced, that is, the air outlet volume of the first air outlet is reduced.

[0073] Specifically, when the second air guide plate 20 is in a closed state, the second air guide plate 20 is in an initial position parallel to the extension direction of the air outlet channel 51; when the air guide plate structure is the third air outlet mode, the second air guide plate 20 rotates a predetermined angle from its initial position toward the inner side of the air outlet channel 51.

[0074] Alternatively, if Figure 4 and Figure 8 As shown, when the above-mentioned predetermined angle is 90 degrees, the second air guide plate 20 is perpendicular to the extension direction of the air outlet channel 51, that is, the second air guide plate 20 is perpendicular to the extension direction of the channel section of the air outlet channel 51 close to its outlet end, so that the second air guide plate 20 can block the airflow in the air outlet channel 51 to the greatest extent, thereby achieving an air supply effect with less air outlet at the top and more air outlet at the bottom.

[0075] Alternatively, if Figure 5 and Fig. 9As shown, when the above-mentioned predetermined angle is an acute angle, the angle between the second air guide plate 20 and the extension direction of the air outlet channel 51 is an acute angle, that is, the angle between the second air guide plate 20 and the extension direction of the channel section of the air outlet channel 51 close to its outlet end is an acute angle, and the second air guide plate 20 has a smaller degree of blocking the airflow in the air outlet channel 51, thereby achieving an air supply effect with more air outlet at the top and less air outlet at the bottom.

[0076] Optionally, when the air guide plate structure is the second air outlet mode or the third air outlet mode, the third air guide plate 30 is perpendicular to the extension direction of the air outlet channel 51, that is, the third air guide plate 30 is perpendicular to the extension direction of the channel section of the air outlet channel 51 close to its outlet end.

[0077] In this embodiment, when the air outlet channel 51 is used to discharge hot air, that is, when the indoor unit of the air conditioner or the air conditioner using the air guide plate structure is in heating mode, the air guide plate structure has three air outlet forms, which are as follows:

[0078] Specifically, Figures 10 to 15 As shown, when the air guide plate structure is in any air outlet form, the first air guide plate 10 is closed, that is, the first air outlet is closed; since the hot air density is relatively small, it is difficult to land on the ground, so the downward air outlet form is adopted to ensure the landing effect of the hot air.

[0079] Specifically, Figures 10 to 12 As shown, when the air guide plate structure is in any air outlet form, the fourth air guide plate 40 is in a stopping state to reduce the hot air in the air outlet channel 51 from spreading toward the first air guide plate 10 .

[0080] Optionally, the angle between the fourth air guide plate 40 and the inner wall surface of the air outlet channel 51 is 90 degrees, that is, the fourth air guide plate 40 is perpendicular to the extension direction of the air outlet channel 51, so that the fourth air guide plate 40 can block the hot air flow in the air outlet channel 51 to the greatest extent.

[0081] Specifically, Fig.10 and Fig.13 As shown, when the air guide plate structure is in the first air outlet form, the second air guide plate 20 and the third air guide plate 30 are both opened toward the inner side of the air outlet channel 51, and the second air outlet is opened at this time, achieving the air outlet effect under heating; and the second air guide plate 20 will block the hot air flow in the air outlet channel 51 to a certain extent, so as to reduce the hot air in the air outlet channel 51 from spreading toward the first air guide plate 10. In addition, this air outlet form is conducive to the aesthetics of the air conditioner indoor unit having the present air guide plate structure.

[0082] Optionally, the free end of the fourth air guide plate 40 is brought into contact with the free end of the second air guide plate 20 to completely block the hot air flow in the air outlet channel 51 to prevent the hot air in the air outlet channel 51 from spreading toward the first air guide plate 10 .

[0083] Optionally, the third air guide plate 30 is made to fit the inner wall of the air outlet channel 51 to prevent the third air guide plate 30 from affecting the airflow in the air outlet channel 51 .

[0084] Specifically, Fig.11 and Fig.14 As shown, when the air guide plate structure is in the second air outlet form, the second air guide plate 20 and the third air guide plate 30 are both opened toward the outside of the air outlet channel 51 to guide and drain the hot air sent out from the second air outlet.

[0085] Optionally, the second air guide plate 20 and the third air guide plate 30 are parallel, and the third air guide plate 30 is perpendicular to the extension direction of the air outlet channel 51, that is, the third air guide plate 30 is perpendicular to the extension direction of the channel section of the air outlet channel 51 close to its outlet end. This air outlet form can optimize the landing effect of the hot air.

[0086] Specifically, Fig.12 and Fig.15 As shown, when the air guide plate structure is in the third air outlet form, the second air guide plate 20 is opened toward the inner side of the air outlet channel 51, and the third air guide plate 30 is opened toward the outer side of the air outlet channel 51. The second air guide plate 20 will block the hot air flow in the air outlet channel 51 to a certain extent, and the third air guide plate 30 is used to guide and drain the hot air sent out from the second air outlet.

[0087] Optionally, the free end of the fourth air guide plate 40 is in contact with the free end of the second air guide plate 20, and the third air guide plate 30 is perpendicular to the extension direction of the air outlet channel 51. This air outlet form is conducive to achieving a rapid heating effect.

[0088] It should be noted that the air outlet form here refers to the air outlet method. In order to distinguish it from the air outlet method in the cooling mode and for the sake of clarity, the air outlet method in the heating mode is used for description.

[0089] The present invention further provides an air conditioner indoor unit, which includes a casing 50 and the above-mentioned air guide plate structure, and the casing 50 encloses an air outlet channel 51.

[0090] Specifically, when the first air guide plate 10 is closed, the free end of the first air guide plate 10 contacts the outside of the cabinet 50 .

[0091] Specifically, the casing 50 also encloses a storage space connected to the air outlet channel 51, and the air conditioner indoor unit also includes an evaporator 70 and a fan 80. The evaporator 70 and the fan 80 are both arranged in the storage space, and the fan 80 is located on one side of the evaporator 70 close to the air outlet channel 51.

[0092] The present invention also provides an air conditioner, which comprises the above-mentioned air conditioner indoor unit.

[0093] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0094] In the air guide plate structure of the present invention, the air guide plate structure is used to be arranged at the outlet end of the air outlet channel 51 and includes a first air guide plate 10, a second air guide plate 20, and a third air guide plate 30 which are arranged in sequence; wherein, the end of the first air guide plate 10 away from the second air guide plate 20 is a free end which can be opened and closed; when the first air guide plate 10 is in an open state, at least a portion of the first air guide plate 10 is inclined upward; the end of the second air guide plate 20 away from the first air guide plate 10 is a free end which can be opened and closed, and the end of the third air guide plate 30 close to the second air guide plate 20 is a free end which can be opened and closed; the second air guide plate 20 and the third air guide plate 30 are both located at the lower part of the air outlet channel 51; when the second air guide plate 20 and the third air guide plate 30 are both in a closed state, the free end of the second air guide plate 20 contacts the free end of the third air guide plate 30.

[0095] By opening the first air guide plate 10, an air outlet, namely the first air outlet, can be formed at the free end of the first air guide plate 10; when the first air guide plate 10 is in the open state, at least a portion of the first air guide plate 10 is tilted upward so that the airflow passing through the first air guide plate 10 flows out tilted upward along the inner wall of the first air guide plate 10, thereby achieving the wind blown out from the first air outlet to be blown out tilted upward; by opening the second air guide plate 20 and / or the third air guide plate 30, another air outlet, namely the second air outlet, can be formed between the second air guide plate 20 and the third air guide plate 30; the second air guide plate 20 and the third air guide plate 30 are both located at the lower part of the air outlet channel 51, so as to achieve the downward delivery of the wind blown out from the second air outlet; when the second air guide plate 20 and the third air guide plate 30 are both closed, the free end of the second air guide plate 20 contacts the free end of the third air guide plate 30, i.e. the second air outlet is closed.

[0096] Furthermore, the structural setting of the first air guide plate 10 of the present application limits the first air guide plate 10 to be opened only toward the outside of the air outlet channel 51, while the structural setting of the second air guide plate 20 and the third air guide plate 30 of the present application can realize that the second air guide plate 20 is opened toward the inside or outside of the air outlet channel 51, and can also realize that the third air guide plate 30 is opened toward the inside or outside of the air outlet channel 51; when the second air guide plate 20 and / or the third air guide plate 30 are opened toward the outside of the air outlet channel 51, the second air guide plate 20 and / or the third air guide plate 30 can guide and divert the wind blown out from the second air outlet; when the second air guide plate 20 is opened toward the inside of the air outlet channel 51, the airflow flowing toward the first air guide plate 10 can be diverted. The third air guide plate 30 is opened toward the inner side of the air outlet channel 51 until it is in contact with the inner wall of the air outlet channel 51, and the third air guide plate 30 will not affect the gas flow in the air outlet channel 51; when the third air guide plate 30 is opened toward the inner side of the air outlet channel 51 and the third air guide plate 30 is set at an angle to the inner wall of the air outlet channel 51, the third air guide plate 30 will stop the airflow in the air outlet channel 51 to a certain extent, so that the airflow flowing to the second air guide plate 20 and the first air guide plate 10 is reduced, and then the instantaneous air output of the first air outlet and the second air outlet is reduced.

[0097] It can be seen that by rotating at least one of the three air guide plates, the air guide plate structure can form a variety of air outlet modes. During specific use, at least one of the three air guide plates can be rotated according to actual needs to adjust the appropriate air outlet mode and improve the air supply comfort. The use of this air guide plate structure can solve the problem of the relatively single air outlet mode of the air guide plate structure of the air conditioner in the prior art.
