Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an indoor air conditioner unit and an air conditioner. Background Technology

[0002] To improve the flexibility and efficiency of air conditioning air delivery while maintaining a clean and aesthetically pleasing appearance, existing technologies typically incorporate an inner air guide plate inside the outer air guide plate. This design effectively balances function and form: when the outer air guide plate is closed, the inner air guide plate can be concealed within it, maintaining the overall flatness of the air conditioner's design; during air delivery, the inner air guide plate assists the outer air guide plate in angle adjustment, jointly achieving precise control of airflow direction and thus improving air delivery performance. However, this structure has significant shortcomings in its driving mechanism. Currently, most solutions require separate driving structures for the outer and inner air guide plates, directly leading to increased manufacturing costs. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an indoor air conditioning unit and an air conditioner.

[0004] In a first aspect, this utility model provides an indoor unit for an air conditioner, comprising: an indoor unit housing having an air outlet; an outer air guide plate rotatably connected to the air outlet, the outer air guide plate being openable to adjust the air outlet direction, or the outer air guide plate being closed to seal the air outlet; an inner air guide plate rotatably connected to the indoor unit housing and located inside the outer air guide plate; a linkage mechanism connected between the outer air guide plate and the inner air guide plate, the linkage mechanism being capable of driving the inner air guide plate to rotate synchronously with the outer air guide plate to assist the outer air guide plate in adjusting the air outlet direction; and a driving mechanism connected to the outer air guide plate and used to drive the outer air guide plate to rotate.

[0005] According to the present invention, an air conditioner indoor unit includes an external air guide plate comprising: a first connecting arm, one end of which is rotatably connected to the indoor unit housing; and an external air guide plate body, which is connected to the other end of the first connecting arm.

[0006] According to the present invention, an indoor air conditioning unit includes an inner air guide plate comprising: a second connecting arm, one end of which is rotatably connected to the housing of the indoor unit; and an inner air guide plate body, which is connected to the other end of the second connecting arm.

[0007] According to the present invention, an indoor air conditioner unit includes a linkage mechanism comprising a connecting rod, one end of which is rotatably connected to the outer air guide plate body, and the other end of which is rotatably connected to the inner air guide plate body.

[0008] According to the present invention, an indoor unit of an air conditioner includes: a housing frame on which the air outlet is provided; a first fixing seat connected to the housing frame and rotatably connected to the first connecting arm; and a second fixing seat connected to the housing frame and rotatably connected to the second connecting arm.

[0009] According to the present invention, an indoor air conditioner unit comprises the following: a first line segment is formed by connecting the first connecting arm to the first fixed base at a rotational connection point and the connecting rod to the outer air guide plate body at a rotational connection point; a second line segment is formed by connecting the second connecting arm to the second fixed base at a rotational connection point and the connecting rod to the inner air guide plate body at a rotational connection point; a third line segment is formed by connecting the first connecting arm to the first fixed base at a rotational connection point and the second connecting arm to the second fixed base at a rotational connection point; and a fourth line segment is formed by connecting the outer air guide plate body to the connecting rod at a rotational connection point and the inner air guide plate body to the connecting rod at a rotational connection point.

[0010] The first line segment is parallel to and equal to the second line segment, and the third line segment is parallel to and equal to the fourth line segment.

[0011] According to the present invention, an indoor air conditioning unit is provided in which the inner air guide plate body and the outer air guide plate body are parallel to each other.

[0012] According to the present invention, an indoor air conditioner unit further includes a control device, which is connected to the drive mechanism and is used to adjust the working state of the drive mechanism based on the operating mode.

[0013] According to the present invention, in an indoor air conditioning unit, both the outer air guide plate and the inner air guide plate are flipped and opened from top to bottom. In heating mode, the control device adjusts the flip angle of the outer air guide plate to a first angle via the drive mechanism. In cooling mode, the control device adjusts the flip angle of the outer air guide plate to a second angle via the drive mechanism. The first angle is greater than the second angle.

[0014] A second aspect of this utility model is to provide an air conditioner, including the indoor unit as described above.

[0015] The air conditioner indoor unit provided by this utility model includes an indoor unit housing, an outer air guide plate, an inner air guide plate, a linkage mechanism, and a drive mechanism. The outer air guide plate is rotatably connected to the air outlet on the indoor unit housing. The outer air guide plate can be flipped open to adjust the air outlet direction, or it can be flipped closed to seal the air outlet. The inner air guide plate is rotatably connected to the indoor unit housing and is located inside the outer air guide plate. The inner air guide plate can be flipped to assist the outer air guide plate in adjusting the air outlet direction. The inner air guide plate is connected to the outer air guide plate through a linkage mechanism, which can drive the inner air guide plate to rotate synchronously with the outer air guide plate.

[0016] During operation, the drive mechanism is activated and acts on the outer air guide plate, causing it to rotate relative to the indoor unit casing. When air is needed, the outer air guide plate flips open. At this time, the linkage mechanism connecting the outer and inner air guide plates transmits the rotation of the outer air guide plate to the inner air guide plate, thereby driving the inner air guide plate to rotate synchronously. The two work together to adjust the airflow direction of the air outlet. When the air conditioner is turned off or air supply needs to be stopped, the drive mechanism operates in reverse, driving the outer air guide plate to flip to the closed position. The linkage mechanism then synchronously drives the inner air guide plate to rotate in the opposite direction, ultimately causing the outer air guide plate to close the air outlet. At the same time, the inner air guide plate is retracted and hidden in the inner space of the outer air guide plate.

[0017] As described above, the inner and outer air guide plates are linked by a linkage mechanism, enabling the inner air guide plate to rotate synchronously with the outer air guide plate. This allows for simultaneous control of the movement of both air guide plates with only one drive mechanism, effectively overcoming the shortcomings of existing technologies that require separate drive structures for each plate, and significantly reducing manufacturing costs. Simultaneously, the inner air guide plate assists the outer air guide plate in adjusting the airflow angle, ensuring precise control of the airflow direction and improving the flexibility and efficiency of air delivery. Furthermore, when the outer air guide plate is closed, the inner air guide plate can be hidden inside, ensuring a clean and aesthetically pleasing overall appearance of the air conditioner unit.

[0018] Furthermore, the air conditioner provided by this utility model, since it includes the indoor unit as described above, also possesses the advantages described above. Attached Figure Description

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The following is combined with Figures 1 to 4 This invention describes an indoor air conditioning unit and an air conditioner according to an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0031] An embodiment of the first aspect of this utility model provides an indoor unit for an air conditioner, such as... Figures 1 to 4As shown, it includes: an indoor unit housing 100, the indoor unit housing 100 having an air outlet; an outer air guide plate, the outer air guide plate being rotatably connected to the air outlet, the outer air guide plate being able to open to adjust the air outlet direction, or the outer air guide plate being able to close to seal the air outlet; an inner air guide plate, the inner air guide plate being rotatably connected to the indoor unit housing 100, and the inner air guide plate being located inside the outer air guide plate; a linkage mechanism, the linkage mechanism being connected between the outer air guide plate and the inner air guide plate, the linkage mechanism being able to drive the inner air guide plate to rotate synchronously with the outer air guide plate to assist the outer air guide plate in adjusting the air outlet direction; and a drive mechanism, the drive mechanism being connected to the outer air guide plate and used to drive the outer air guide plate to rotate.

[0032] The indoor unit of the air conditioner provided by this utility model includes an indoor unit housing 100, an outer air guide plate, an inner air guide plate, a linkage mechanism, and a drive mechanism. The outer air guide plate is rotatably connected to the air outlet on the indoor unit housing 100. The outer air guide plate can be flipped open to adjust the air outlet direction, or it can be flipped closed to seal the air outlet. The inner air guide plate is rotatably connected to the indoor unit housing 100 and is located inside the outer air guide plate. The inner air guide plate can be flipped to assist the outer air guide plate in adjusting the air outlet direction. The inner air guide plate is connected to the outer air guide plate through a linkage mechanism, which can drive the inner air guide plate to rotate synchronously with the outer air guide plate.

[0033] During operation, the drive mechanism is activated and acts on the outer air guide plate, causing it to rotate relative to the indoor unit casing 100. When air is needed, the outer air guide plate flips open. At this time, the linkage mechanism connecting the outer air guide plate and the inner air guide plate transmits the rotation of the outer air guide plate to the inner air guide plate, thereby driving the inner air guide plate to rotate synchronously. The two work together to adjust the air supply direction of the air outlet. When the air conditioner is turned off or the air supply needs to be stopped, the drive mechanism operates in the opposite direction, driving the outer air guide plate to flip to the closed position. The linkage mechanism then synchronously drives the inner air guide plate to rotate in the opposite direction, ultimately causing the outer air guide plate to close the air outlet. At the same time, the inner air guide plate is retracted and hidden in the inner space of the outer air guide plate.

[0034] As described above, the inner and outer air guide plates are linked by a linkage mechanism, enabling the inner air guide plate to rotate synchronously with the outer air guide plate. This allows for simultaneous control of the movement of both air guide plates with only one drive mechanism, effectively overcoming the shortcomings of existing technologies that require separate drive structures for each plate, and significantly reducing manufacturing costs. Simultaneously, the inner air guide plate assists the outer air guide plate in adjusting the airflow angle, ensuring precise control of the airflow direction and improving the flexibility and efficiency of air delivery. Furthermore, when the outer air guide plate is closed, the inner air guide plate can be hidden inside, ensuring a clean and aesthetically pleasing overall appearance of the air conditioner unit.

[0035] In one embodiment of the present invention, the outer air guide plate includes: a first connecting arm 220, one end of which is rotatably connected to the inner casing 100; and an outer air guide plate body 210, which is connected to the other end of the first connecting arm 220.

[0036] In one embodiment of the present invention, the inner air guide plate includes: a second connecting arm 320, one end of which is rotatably connected to the inner unit housing 100; and an inner air guide plate body 310, which is connected to the other end of the second connecting arm 320.

[0037] In another embodiment of the present invention, the linkage mechanism includes a connecting rod 400, one end of which is rotatably connected to the outer air guide plate body 210, and the other end of which is rotatably connected to the inner air guide plate body 310.

[0038] Furthermore, in one embodiment of this utility model, the indoor unit housing 100 includes: a housing frame with an air outlet; a first fixing seat 510 connected to the housing frame and rotatably connected to a first connecting arm 220; and a second fixing seat 520 connected to the housing frame and rotatably connected to a second connecting arm 320.

[0039] In one embodiment of this utility model, the line connecting the rotational connection point between the first connecting arm 220 and the first fixed seat 510 and the rotational connection point between the connecting rod 400 and the outer air guide plate body 210 constitutes a first line segment 610; the line connecting the rotational connection point between the second connecting arm 320 and the second fixed seat 520 and the rotational connection point between the connecting rod 400 and the inner air guide plate body 310 constitutes a second line segment 620; the line connecting the rotational connection point between the first connecting arm 220 and the first fixed seat 510 and the rotational connection point between the second connecting arm 320 and the second fixed seat 520 constitutes a third line segment 630; and the line connecting the rotational connection point between the outer air guide plate body 210 and the connecting rod 400 and the rotational connection point between the inner air guide plate body 310 and the connecting rod 400 constitutes a fourth line segment 640.

[0040] The first line segment 610 is parallel to and equal to the second line segment 620, and the third line segment 630 is parallel to and equal to the fourth line segment 640.

[0041] In another embodiment of this utility model, the inner air guide plate body 310 and the outer air guide plate body 210 are parallel to each other.

[0042] Specifically, such as Figures 1 to 4As shown, the first fixing seat 510 and the second fixing seat 520 are respectively fixedly connected to corresponding positions on the shell frame. One end of the first connecting arm 220 is rotatably connected to the first fixing seat 510, and the other end of the first connecting arm 220 is fixedly connected to the inner side of the outer air guide plate. One end of the second connecting arm 320 is rotatably connected to the second fixing seat 520, and the other end of the second connecting arm 320 is fixedly connected to the inner side of the inner air guide plate. The connecting rod 400 connects between the inner air guide plate body 310 and the outer air guide plate body 210. The inner air guide plate body 310 and the outer air guide plate body 210 are kept parallel. The lines connecting the rotating connection points of the first connecting arm 220 and the first fixed seat 510, and the connecting rod 400 and the outer air guide plate body 210, constitute a first line segment 610; the lines connecting the rotating connection points of the second connecting arm 320 and the second fixed seat 520, and the connecting rod 400 and the inner air guide plate body 310, constitute a second line segment 620; the lines connecting the rotating connection points of the first connecting arm 220 and the first fixed seat 510, and the connecting arm 320 and the second fixed seat 520, constitute a third line segment 630; the lines connecting the rotating connection points of the outer air guide plate body 210 and the connecting rod 400, and the inner air guide plate body 310 and the connecting rod 400, constitute a fourth line segment 640. The first line segment 610 and the second line segment 620 are parallel and equal in length, and the third line segment 630 and the fourth line segment 640 are parallel and equal in length. In other words, the first line segment 610, the second line segment 620, the third line segment 630, and the fourth line segment 640 together form a parallelogram. Therefore, during the process of the drive mechanism driving the outer air guide plate body 210 to rotate, the connecting rod 400 can drive the inner air guide plate body 310 to rotate synchronously and parallel with the outer air guide plate body 210.

[0043] In one embodiment of the present invention, the indoor unit of the air conditioner further includes a control device, which is connected to the drive mechanism and is used to adjust the working state of the drive mechanism based on the operating mode.

[0044] Furthermore, in one embodiment of this utility model, the flipping and opening directions of both the outer and inner air guide plates are from top to bottom; in heating mode, the control device adjusts the flipping angle of the outer air guide plate to a first angle via the drive mechanism; in cooling mode, the control device adjusts the flipping angle of the outer air guide plate to a second angle via the drive mechanism. The first angle is greater than the second angle.

[0045] Air conditioner indoor units operate in at least two modes: cooling and heating. Since cold air, being denser, tends to sink, while hot air, being less dense, tends to rise, air conditioners adjust the airflow angle upwards in cooling mode to promote the natural sinking and even diffusion of cold air throughout the space, preventing direct cold air from blowing on people and thus improving cooling efficiency and comfort. In heating mode, the airflow angle is set downwards to help hot air circulate downwards, reducing heat accumulation near the ceiling and accelerating the overall indoor temperature rise, achieving a more efficient and balanced heating effect.

[0046] For example, such as Figure 1 As shown, when the outer air guide plate body 210 is in the closed state, it extends obliquely upwards. For example, in the closed state, the angle between the outer air guide plate body 210 and the horizontal plane is 15°. The opening direction of the outer air guide plate body 210 is roughly from top to bottom; that is, along the top-to-bottom direction, the opening angle of the outer air guide plate body 210 gradually increases. The inner air guide plate body 310 can also rotate synchronously and parallel to the outer air guide plate body 210.

[0047] For example, such as Figure 2 As shown, in cooling mode, the control device can control the working state of the drive mechanism to cause the outer air guide plate body 210 to flip open by 30°, that is, the aforementioned second angle is set to 30°. For example, as... Figure 3 As shown, in cooling mode, the control device can also control the working state of the drive mechanism to cause the outer air guide plate body 210 to flip open by 55°, that is, the second angle mentioned above is set to 55°. Figure 4 As shown, in heating mode, the control device can control the working state of the drive mechanism to cause the outer air guide plate body 210 to rotate and open by 100°, that is, the first angle is set to 100°. The cooling airflow discharged from the air outlet can be guided to a relatively upward direction by the channel between the inner air guide plate body 310 and the outer air guide plate body 210. The heating airflow discharged from the air outlet can be guided to a relatively downward direction by the channel between the inner air guide plate body 310 and the outer air guide plate body 210.

[0048] It should be noted that the above embodiments are merely illustrative examples of this utility model and do not constitute any limitation on this utility model. For example, 30° ≤ second angle ≤ 55°, 55° < first angle ≤ 100°.

[0049] A second aspect of this utility model provides an air conditioner, including the indoor unit described above.

[0050] Furthermore, the air conditioner provided by this utility model, since it includes the indoor unit as described above, also possesses the advantages described above.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
