Description

Technical Field

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

[0002] A wall-mounted air conditioner indoor unit is a type of air conditioner indoor unit that is suspended from the wall. It has an air inlet at the top and an air outlet at the lower front. An air guide plate is installed at the air outlet. A heat exchanger and a cross-flow fan are installed in the air duct between the air inlet and outlet. During operation, air enters the air duct from the air inlet under the action of the cross-flow fan, undergoes heat exchange in the heat exchanger, and is blown out from the air outlet. The angle of the air guide plate can be adjusted to direct the airflow forward or downward. However, the rotation angle of the air guide plate is limited, and the air outlet method of the indoor unit is singular. This may result in problems such as direct airflow onto the user or a large vertical temperature difference, failing to meet the airflow needs of various users. Utility Model Content

[0019] The second grid strip is disposed above the third grid strip, and the second grid strip and the third grid strip are inclined, and the inclination directions of the second grid strip and the third grid strip are different.

[0020] Optionally, the second grille bar directs air upwards at an angle, and the third grille bar directs air downwards at an angle.

The air outlet grille can also be tilted to control the airflow direction. By guiding the airflow through multiple guide vanes and the air outlet grille, airflow resistance is reduced, thereby minimizing airflow loss, increasing airflow volume, and improving the air conditioning's performance. Furthermore, the combination of multiple guide vanes and the air outlet grille diversifies the airflow pattern of the indoor unit, meeting different user needs and enhancing the user experience.

[0029] Preferably, the indoor unit of the air conditioner is a wall-mounted indoor unit.

[0045] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 9 The arrows in the diagram indicate the direction of airflow. This embodiment of the invention provides an indoor air conditioning unit 100, including a housing 10, an air outlet grille 30, and multiple guide vanes. An air outlet 20 is provided on the front wall of the housing 10. The air outlet grille 30 is located at the air outlet 20. Multiple guide vanes are sequentially arranged along the vertical direction inside the air outlet grille 30, and each guide vane is rotatably mounted.

[0046] In this embodiment, the air outlet 20 of the indoor unit 100 is located at the front, and multiple guide vanes are provided inside the air outlet 20. An air outlet grille 30 is also provided at the air outlet 20. When the indoor unit 100 supplies air to the room, the airflow first passes through the guide vanes and then through the air outlet grille 30 before being blown into the room. Since the guide vanes are rotatable, rotating them to different angles allows the indoor unit 100 to supply air in different directions, preventing direct airflow from the user and reducing temperature differences within the room. The air outlet grille 30 can also control the airflow direction of the indoor unit 100 by setting a certain tilt angle. By guiding the airflow through multiple guide vanes and the air outlet grille 30, the airflow resistance is reduced, thereby reducing airflow loss, increasing airflow volume, and improving the air conditioning's airflow performance. Furthermore, the combination of multiple guide vanes and the air outlet grille 30 diversifies the airflow patterns of the indoor unit 100, meeting different user airflow needs and improving the user experience.

[0047] In some embodiments of this utility model, the area of ​​the air outlet 20 is more than 80% of the area of ​​the front wall. The ratio of the height of the air outlet 20 to the height of the front wall is greater than or equal to 4 / 5, and the ratio of the width of the air outlet 20 to the width of the front wall is greater than or equal to 4 / 5.

[0048] In this embodiment, the area of ​​the air outlet 20 accounts for more than 80% of the area of ​​the front wall, increasing the air volume and air delivery range of the indoor air conditioning unit 100, reducing the temperature difference in the indoor area, and improving the air delivery effect of the indoor air conditioning unit 100. This, in turn, meets the different air blowing needs of users and improves the user experience. For example, the area of ​​the air outlet 20 is 80%, 85%, 90%, 95%, or 100% of the area of ​​the front wall. The larger the area of ​​the air outlet 20, the larger the air delivery range and the greater the air volume of the indoor air conditioning unit 100, thereby improving the air delivery effect of the indoor air conditioning unit 100 and enhancing the user experience.

[0049] Furthermore, in some embodiments of this utility model, such as Figure 1 As shown, the area of ​​the air outlet 20 is 100% of the area of ​​the front wall of the housing 10. The ratio of the height of the air outlet 20 to the height of the front wall is 1, and the ratio of the width of the air outlet 20 to the width of the front wall is 1.

[0050] In this embodiment, the entire front side of the housing 10 is an air outlet 20, increasing the area of ​​the air outlet 20, thereby increasing the air supply range and air volume, improving the air supply effect of the indoor air conditioning unit 100, and enhancing the user experience. Furthermore, since there is no wall obstructing the air outlet 20 on the front side of the housing 10, the angle at which the airflow blows out from the air outlet 20 increases, further increasing the air supply range of the indoor air conditioning unit 100, reducing the temperature difference in the indoor area, and improving the air supply effect of the indoor air conditioning unit 100.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the indoor unit 100 of the air conditioner also includes a heat exchanger 50. The upper edge of the air outlet 20 is located above the heat exchanger 50, and the lower edge of the air outlet 20 is located below the heat exchanger 50. The ratio of the distance between the heat exchanger 50 and the air outlet 20 to the distance between the upper and lower edges of the air outlet 20 is 7:1.

[0052] In this embodiment, the heat exchanger 50 is located between the upper and lower edges of the air outlet 20 in the vertical direction. All the airflow after heat exchange in the heat exchanger 50 is blown out from the air outlet 20, which improves the air outlet efficiency of the indoor unit 100 of the air conditioner and avoids the airflow after heat exchange in the heat exchanger 50 being blown onto the casing 10, which would reduce the airflow.

[0053] In some embodiments of this utility model, the indoor unit 100 of the air conditioner further includes one or more axial flow fans 60, which are disposed inside the housing 10 and located behind the air outlet 20. The axial flow fans 60 are configured to discharge air horizontally to the front. Further, the axial flow fans 60 are located behind the heat exchanger 50.

[0054] In this embodiment, the axial fan 60 is located behind the air outlet 20. The airflow first passes through the axial fan 60 and then enters the heat exchanger 50 for heat exchange. The axial fan 60 has a small cross-sectional area, so when setting the air inlet, the air inlet area can be made as large as possible, thereby increasing the air intake of the indoor unit 100 and thus increasing the air output of the indoor unit 100.

[0055] Furthermore, by supplying air to the outside via the axial flow fan 60, compared to a cross-flow fan, the axial flow fan 60 can provide a larger air volume during operation, further increasing the air volume output of the indoor unit 100. In addition, the axial flow fan 60 is characterized by low noise, maintaining a lower noise level during operation, making it more suitable for indoor environments and enhancing the user experience.

[0056] In some embodiments of this utility model, the ratio of the distance between the heat exchanger 50 and the air outlet 20 to the distance between the upper edge and the lower edge of the air outlet 20 is 7:1.

[0057] In some embodiments of this utility model, such as Figure 2 As shown, the air outlet grille 30 includes a plurality of first grille strips 311, which are arranged in parallel and are fixedly connected to the housing 10.

[0058] In this embodiment, the air outlet grille 30 includes a plurality of parallel first grille strips 311, with channels formed between the first grille strips 311, through which airflow is blown outward. The plurality of first grille strips 311 guide the airflow outward, and the airflow flows along the surface of the first grille strips 311, reducing the flow resistance of the airflow, thereby reducing the loss of airflow volume, and thus improving the air outlet effect of the air conditioning indoor unit 100 and enhancing the user experience.

[0059] In some embodiments of this utility model, such as Figure 5 and Figure 8 As shown, the air outlet grille 30 includes a first air outlet grille section 320 and a second air outlet grille section 330. The first air outlet grille section 320 includes a plurality of second grille bars 321, which extend in a left-right direction. The second air outlet grille section 330 includes a plurality of third grille bars 331, which extend in a left-right direction. The second grille bars 321 are disposed above the third grille bars 331, and the second grille bars 321 and the third grille bars 331 are inclined, with the inclination directions of the second grille bars 321 and the third grille bars 331 being different.

[0060] In this embodiment, the air outlet grille 30 includes a plurality of second grille strips 321 and a plurality of third grille strips 331 located below the second grille strips 321. The second grille strips 321 and the third grille strips 331 are inclined in different directions, thereby making the air outlet directions of the second grille strips 321 and the third grille strips 331 different. That is, the first air outlet grille section 320 and the second air outlet grille section 330 send air in different directions, which increases the air supply angle and air supply range of the air conditioner indoor unit 100, thereby diversifying the air outlet form of the air conditioner indoor unit 100, meeting the different air blowing needs of users, and improving the user experience.

[0061] In some embodiments of this utility model, such as Figures 5 to 7 As shown, the second grille bar 321 directs air upwards at an angle, and the third grille bar 331 directs air downwards at an angle. The angle between the second grille bar 321 and the front wall gradually increases from top to bottom. The angle between the third grille bar 331 and the front wall gradually decreases from top to bottom.

[0062] In this embodiment, the second grille strip 321 slopes downwards from front to back, with the angle of inclination increasing from bottom to top. The third grille strip 331 slopes upwards from front to back, with the angle of inclination increasing from top to bottom. That is, the second and third grille strips 321 and 331 are arranged in an outward diverging pattern, distributing air outwards and increasing the air delivery angle and range of the indoor unit 100, thereby enhancing the diversity of air output from the indoor unit 100, improving the air delivery effect of the air conditioner, and enhancing the user experience.

[0063] In some embodiments of this utility model, such as Figure 8 As shown, the second grille bar 321 directs air downwards at an angle, while the third grille bar 331 directs air upwards at an angle. The angle between the second grille bar 321 and the front wall gradually increases from top to bottom. The angle between the third grille bar 331 and the plane containing the front wall gradually decreases from top to bottom.

[0064] In this embodiment, the second grille strip 321 slopes upwards from front to back, with the angle of inclination increasing from bottom to top. The third grille strip 331 slopes downwards from front to back, with the angle of inclination increasing from top to bottom. That is, the second and third grille strips 321 converge, and their outward convergence of airflow makes the airflow from the indoor unit 100 more concentrated, increasing the airflow distance and improving the diversity of airflow from the indoor unit 100. This, in turn, enhances the airflow performance of the air conditioner and improves the user experience.

[0065] In some embodiments of this utility model, the multiple guide vanes are divided into one guide vane group or multiple guide vane groups. The air conditioner indoor unit 100 also includes a drive mechanism, and one or more drive mechanisms are provided. The drive mechanism is arranged in a one-to-one correspondence with the guide vane group, and each drive mechanism is used to drive the corresponding guide vane group to rotate.

[0066] In this embodiment, a drive mechanism drives multiple guide vanes to rotate. When a set of guide vane groups is set, there is one drive mechanism, and the multiple guide vanes within the guide vane group rotate synchronously. When multiple guide vane groups are set, each drive mechanism drives one group of guide vanes to rotate, and the guide vanes within a guide vane group rotate synchronously. The guide vanes driven by multiple drive mechanisms can rotate at different angles, so that the guide vanes guide air in multiple directions, improving the diversity of air output from the indoor unit 100 of the air conditioner, thereby improving the air output effect of the air conditioner, meeting the air blowing needs of different users, and enhancing the user experience.

[0067] In some embodiments of this utility model, such as Figure 2 As shown, a portion of the multiple guide vanes forms a first guide vane group 410, and another portion forms a second guide vane group 420. The first guide vane group 410 is positioned above the second guide vane group 420, and the first and second guide vanes extend laterally. The guide vanes of the first guide vane group 410 rotate synchronously, and the guide vanes of the second guide vane group 420 rotate synchronously.

[0068] In this embodiment, the multiple air guides are divided into a first air guide group 410 at the top and a second air guide group 420 at the bottom. The first air guide group 410 and the second air guide group 420 guide the airflow to flow in two directions, thereby increasing the diversity of air output from the indoor unit 100 of the air conditioner, improving the air output effect of the air conditioner, meeting the air blowing needs of different users, and improving the user experience.

[0069] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the first deflector assembly 410 and the second deflector assembly 420 can rotate to a forward-downward tilting position. When the first deflector assembly 410 and the second deflector assembly 420 are in the forward-downward tilting position, the angle between the first deflector assembly 410 and the horizontal plane is greater than or equal to the angle between the second deflector assembly 420 and the horizontal plane. The first deflector assembly 410 and the second deflector assembly 420 can rotate to a forward-upward tilting position. When the first deflector assembly 410 and the second deflector assembly 420 are in the forward-upward tilting position, the angle between the first deflector assembly 410 and the horizontal plane is less than or equal to the angle between the second deflector assembly 420 and the horizontal plane.

[0070] In this embodiment, when the first guide vane group 410 and the second guide vane group 420 simultaneously guide airflow forward and downward, the angle between the first guide vane group 410 and the horizontal plane is greater than or equal to the angle between the second guide vane group 420 and the horizontal plane. That is, the tilt angles of the first guide vane group 410 and the second guide vane group are the same, or the downward tilt angle of the first guide vane group 410 is greater than the downward tilt angle of the second guide vane group 420. In this case, it is more suitable to blow hot air into the room, directing the hot air downwards and then allowing it to diffuse upwards within the room, preventing large temperature differences in the vertical direction and thus improving the user experience. When the first guide vane assembly 410 and the second guide vane assembly 420 simultaneously guide airflow forward and upward, the angle between the first guide vane assembly 410 and the horizontal plane is less than or equal to the angle between the second guide vane assembly 420 and the horizontal plane. That is, the tilt angles of the first guide vane assembly 410 and the second guide vane assembly 420 are the same, or the upward angle of the second guide vane assembly 420 is greater than the upward angle of the first guide vane assembly 410. In this case, it is more suitable to blow cool air into the room, directing the cool air diagonally upward, and then diffusing it downwards within the room, avoiding direct cold air blowing on the user and affecting their health, thus improving the user experience. The airflow angles of the first guide vane assembly 410 and the second guide vane assembly 420 can be adjusted according to different airflow types to meet different user needs, thereby improving the user experience.

[0071] In other embodiments of this utility model, such as Figure 4 As shown, the first guide vane assembly 410 can be rotated to a position tilted forward and downward, and the second guide vane assembly 420 can be rotated to a position tilted forward and upward. When the first guide vane assembly 410 tilts forward and downward and the second guide vane assembly 420 tilts forward and upward, the angle between the first guide vane assembly 410 and the horizontal plane is equal to the angle between the second guide vane assembly 420 and the horizontal plane.

[0072] In this embodiment, the first guide vane group 410 guides the airflow forward and downward, and the second guide vane group 420 guides the airflow forward and upward, so that the airflow is concentrated at the middle position, the air supply of the air conditioner indoor unit 100 is more concentrated, the air supply distance of the air conditioner indoor unit 100 is increased, thereby improving the air supply effect of the air conditioner indoor unit 100 and improving the user experience.

[0073] In some other embodiments of the present invention, the first guide vane assembly 410 can be rotated to a position tilted forward and upward, and the second guide vane assembly 420 can be rotated to a position tilted forward and downward. When the first guide vane assembly 410 is tilted forward and upward and the second guide vane assembly 420 is tilted forward and downward, the angle between the first guide vane assembly 410 and the horizontal plane is equal to the angle between the second guide vane assembly 420 and the horizontal plane.

[0074] In this embodiment, the first guide vane group 410 guides air forward and upward, and the second guide vane group 420 guides air forward and downward, so that the airflow above blows out diagonally upward and the airflow below blows out diagonally downward. That is, the air conditioner indoor unit 100 diffuses and delivers air to the front side, thereby improving the air delivery angle and air delivery range of the air conditioner indoor unit 100, and thus improving the air delivery effect of the air conditioner indoor unit 100 and improving the user experience.

[0075] In some embodiments of this utility model, the air outlet grille 30 delivers air in three ways: horizontal forward airflow, outward diffusion airflow, and inward convergence airflow. The guide vanes guide air in three ways: forward convergence airflow from the first guide vane group 410 and the second guide vane group 420; upward oblique airflow; and downward oblique airflow. Upward oblique airflow includes two cases: the first guide vane group 410 and the second guide vane group 420 have the same tilt angle, and the angle between the first guide vane group 410 and the horizontal plane is smaller than the angle between the second guide vane group 420 and the horizontal plane. Downward oblique airflow includes two cases: the first guide vane group 410 and the second guide vane group 420 have the same tilt angle, and the angle between the first guide vane group 410 and the horizontal plane is larger than the angle between the second guide vane group 420 and the horizontal plane. The air outlet grille 30 and the guide vanes can be combined, giving the indoor air conditioning unit 100 multiple air outlet methods to meet different user needs and improve the user experience.

[0076] In some embodiments of this utility model, such as Figure 9 As shown, the housing 10 includes an air inlet shroud 110, which is located behind the axial flow fan 60. The air inlet shroud 110 includes a rear housing 111 and a side housing 112. The rear housing 111 has a first air inlet 710. The side housing 112 is inclined and surrounds the rear housing 111. The side housing 112 has a second air inlet 720.

[0077] In this embodiment, the air inlet cover 110 includes a rear cover 111 and a side cover 112. The rear cover 111 is provided with a first air inlet 710 and the side cover 112 is provided with a second air inlet 720. That is, the airflow enters from the rear and periphery of the air conditioner indoor unit 100, thereby increasing the air intake volume of the air conditioner indoor unit 100, thereby increasing the air output volume of the air conditioner indoor unit 100, and thus improving the air output effect of the air conditioner indoor unit 100 and improving the user experience.

[0078] In some embodiments of this utility model, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, or other air conditioner indoor units.

[0079] Preferably, the indoor unit 100 is a wall-mounted indoor unit.
