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 that is suspended from a 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 housed in the air duct between the inlet and outlet. During operation, air enters the air duct from the inlet under the action of the cross-flow fan, undergoes heat exchange in the heat exchanger, and is blown out from the outlet. The angle of the air guide plate can be adjusted to direct the airflow forward or downward. However, when the indoor unit blows air into the room, the airflow velocity of the heat exchanged air is relatively high, blowing directly onto the user, resulting in a strong blowing sensation and affecting the user experience. Utility Model Content

[0003] In view of the above problems, this utility model is proposed to provide an air conditioner indoor unit that overcomes or at least partially solves the above problems.

[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 refer to Figures 2 to 6 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, a diffuser mechanism 30, and multiple guide plates 40. An air outlet 20 is provided on the housing 10. The diffuser mechanism 30 is located at the air outlet 20. Multiple guide plates 40 are sequentially arranged along the vertical direction inside the diffuser mechanism 30, and each guide plate 40 is rotatably mounted.

[0046] In this embodiment, a diffuser mechanism 30 is provided at the air outlet 20, and multiple guide vanes 40 are provided inside the air outlet 20. These guide vanes 40 are rotatable to guide airflow in different directions. When the indoor unit 100 blows air outwards, the guide vanes 40 guide the airflow towards the diffuser mechanism 30. As the airflow passes through the diffuser mechanism 30, it rectifies the airflow, causing it to be blown outwards evenly. The diffuser mechanism 30 makes the blown airflow gentler, improving human comfort and enhancing the user experience. Furthermore, the diffuser mechanism 30 has a certain rectification effect, ensuring that the airflow is evenly distributed into the room, reducing temperature differences within the room and further improving the user experience.

[0047] Furthermore, the deflector 40 can direct airflow in multiple directions, preventing it from blowing directly onto the user, or directing it in a specific direction to meet different airflow needs and further enhance the user experience.

[0048] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the diffuser mechanism 30 includes a diffuser plate 310, on which a plurality of micro-holes 320 are formed. The total area of ​​the micro-holes 320 accounts for 60% to 70% of the area of ​​the diffuser plate 310.

[0049] In this embodiment, the diffuser mechanism 30 is a diffuser plate 310 including multiple micro-holes 320. The diffuser plate 310 disperses the heat-exchanged airflow into smaller airflows, preventing the airflow from blowing directly onto the human body at a high speed, making the airflow gentler, improving the comfort of the human body, and enhancing the user experience. Furthermore, the micro-holes 320 make the airflow distribution more uniform, reducing temperature differences in indoor areas, thereby improving the user experience.

[0050] Furthermore, the total area of ​​the micro-holes 320 accounts for 60% to 70% of the area of ​​the diffuser 310. The higher the proportion of the total area of ​​the micro-holes 320 to the area of ​​the diffuser 310, the more uniform the airflow distribution, the smaller the airflow loss, and the larger the air volume output of the indoor unit 100. However, as the ratio of the total area of ​​the micro-holes 320 to the area of ​​the diffuser 310 increases, the structural stability of the diffuser 310 gradually decreases, thereby reducing the durability and safety of the diffuser 310. Therefore, the ratio of the total area of ​​the micro-holes 320 to the area of ​​the diffuser 310 must be within a suitable range. For example, the total area of ​​the micro-holes 320 accounts for 60%, 65%, or 70% of the area of ​​the diffuser 310.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the micropores 320 are circular.

[0052] In this embodiment, the micro-holes 320 can be circular. Circular micro-holes 320 are more evenly distributed on the diffuser 310, allowing airflow to be more evenly distributed into the room after passing through the diffuser 310. This results in a lower temperature difference between indoor areas, thereby improving the user experience. Furthermore, the manufacturing process of circular micro-holes 320 is relatively simple, thus reducing the production cost of the diffuser 310 and consequently, the production cost of the air conditioner.

[0053] In some embodiments of this invention, the micropores 320 are polygonal.

[0054] In this embodiment, the edges of the polygonal micro-holes 320 are straight lines. When the micro-holes 320 are arranged, the edges of multiple micro-holes 320 are easy to align, thereby increasing the number of micro-holes 320, increasing the total area of ​​micro-holes 320, increasing the ratio of the total area of ​​micro-holes 320 to the area of ​​diffuser plate 310, thereby increasing the air volume of air conditioner indoor unit 100.

[0055] Furthermore, in some embodiments of this utility model, such as Figure 1 As shown, the micropores 320 are rectangular.

[0056] In some other embodiments of this invention, some micropores 320 are circular, and some micropores 320 are rectangular. In the arrangement, the circular micropores 320 are located on one side of the rectangular micropores 320. Alternatively, the circular micropores 320 are located around the rectangular micropores 320. Alternatively, the rectangular micropores 320 are located around the circular micropores 320. Alternatively, the circular micropores 320 and the rectangular micropores 320 are arranged alternately.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, multiple micropores 320 are distributed in a matrix.

[0058] In this embodiment, the micropores 320 are arranged in a matrix. The arrangement of the micropores 320 is relatively neat and uniform, which allows the airflow to be blown into the room evenly after passing through the diffuser plate 310, thereby improving the uniformity of the air outlet of the indoor unit 100 of the air conditioner, and thus improving the uniformity of the indoor temperature distribution, thereby improving the user's comfort and user experience.

[0059] In some embodiments of this utility model, such as Figure 2 As shown, the micropores 320 are arranged in multiple rows, and the micropores 320 are arranged sequentially along the width direction of the diffuser plate 310. In each adjacent pair of rows of micropores 320, one row of micropores 320 and the other row of micropores 320 are arranged alternately along the length direction of the diffuser plate 310.

[0060] In this embodiment, the micro-holes 320 on the diffuser 310 are arranged alternately, meaning that the areas surrounding each micro-hole 320 are non-micro-hole positions, and the areas surrounding each non-micro-hole position are micro-holes 320. This alternating arrangement of the micro-holes 320 makes them more orderly and uniform, allowing airflow to be evenly distributed into the room after passing through the diffuser 310. This improves the uniformity of airflow from the indoor unit 100, thereby improving the uniformity of indoor temperature distribution and ultimately enhancing user comfort and overall user experience.

[0061] In some embodiments of this invention, the diameter of the micropore 320 is 2 mm to 4 mm.

[0062] In this embodiment, the smaller the diameter of the micro-orifice 320, the more it compresses the airflow, thereby increasing the wind speed and resulting in a higher wind speed of the airflow exiting the micro-orifice 320. Simultaneously, due to the increased airflow speed, noise is generated as the airflow passes through the micro-orifice 320, thus increasing noise levels. An appropriate micro-orifice 320 diameter can balance wind speed and noise, reducing unnecessary noise pollution. For example, the diameter of the micro-orifice 320 can be 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.

[0063] Preferably, the diameter of the micropore 320 is 3 mm.

[0064] In some embodiments of this utility model, such as Figure 3 As shown, the air outlet 20 is disposed on the front surface of the housing 10, and the area of ​​the air outlet 20 accounts for more than 80% of the area of ​​the front surface of the housing 10.

[0065] In this embodiment, the area of ​​the air outlet 20 is at least 80% of the front surface of the housing 10. Increasing the area of ​​the air outlet 20 increases the air volume and air delivery range of the indoor unit 100, reduces the temperature difference in the indoor area, and improves the air delivery effect of the indoor unit 100, thereby meeting different user airflow needs and enhancing the user experience. For example, the area of ​​the air outlet 20 can be 80%, 85%, 90%, 95%, or 100% of the front wall area. The larger the area of ​​the air outlet 20, the larger the air delivery range and the greater the air volume of the indoor unit 100, thus improving the air delivery effect of the indoor unit 100 and enhancing the user experience.

[0066] 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 surface of the housing 10.

[0067] 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.

[0068] In some embodiments of this utility model, such as Figure 3 As shown, the micropore 320 is perpendicular to the diffuser plate 310.

[0069] In this embodiment, the micro-holes 320 are perpendicular to the diffuser plate 310, meaning that when the airflow flows out from the micro-holes 320, it is blown outward in a direction perpendicular to the diffuser plate 310. When the micro-holes 320 are perpendicular to the diffuser plate 310, the frictional force experienced by the airflow through the micro-holes 320 is small, and the airflow loss is small, resulting in a larger airflow velocity and a larger airflow volume, which meets the user's airflow needs and is more suitable for occasions requiring rapid heat dissipation or ventilation.

[0070] In some embodiments of this utility model, the micropores 320 are arranged at an angle from front to back towards the top.

[0071] In this embodiment, the tilted arrangement of the micro-holes 320 guides airflow in a specific direction. In the design of the air conditioner outlet 20, the micro-holes 320 can be tilted forward and upward, causing the cold air to blow upwards and gradually diffuse downwards within the room, preventing direct cold air from blowing on the user, reducing the vertical temperature difference, and resulting in a more uniform temperature distribution within the room. Furthermore, the tilted arrangement of the micro-holes 320 increases the resistance encountered by the airflow, reducing airflow speed and making the airflow gentler, improving human comfort and enhancing the user experience. An appropriate tilt angle can also reduce noise generated when airflow passes through the micro-holes 320, thereby reducing the noise level of the air conditioner during operation and further improving the user experience.

[0072] In some embodiments of this utility model, the micropores 320 are arranged at an angle downwards from front to back.

[0073] In this embodiment, the tilted arrangement of the micro-holes 320 guides airflow in a specific direction. In the design of the air conditioner outlet 20, the micro-holes 320 can be tilted forward and downward, causing the hot air to blow downwards and gradually diffuse upwards within the room, thus reducing the vertical temperature difference and resulting in a more uniform temperature distribution within the room. Furthermore, the tilted arrangement of the micro-holes 320 increases the resistance encountered by the airflow, reducing airflow speed and making the airflow gentler, improving human comfort and enhancing the user experience. An appropriate tilt angle can also reduce noise generated when airflow passes through the micro-holes 320, thereby reducing the noise level of the air conditioner during operation and further improving the user experience.

[0074] In some embodiments of this utility model, such as Figures 3 to 6 As shown, the indoor unit 100 of the air conditioner also includes an axial flow fan 60 and a heat exchanger 50. There are two axial flow fans 60 arranged horizontally and housed inside the casing 10. The heat exchanger 50 is housed inside the casing 10 and is located between the axial flow fans 60 and the air outlet 20.

[0075] In this embodiment, the axial fan 60 is located behind the heat exchanger 50. The airflow passes through the axial fan 60 before entering the heat exchanger 50 for heat exchange. The axial fan 60 has a small cross-sectional area, so when setting the air inlet 70, the air inlet area of ​​the air inlet 70 can be made as large as possible, thereby increasing the air intake volume of the indoor unit 100 and thus increasing the air output volume of the indoor unit 100.

[0076] 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.

[0077] In some embodiments of this utility model, such as Figure 3 As shown, multiple guide vanes 40 extend in the left and right directions, and the guide vanes 40 are set at an angle from front to back downwards.

[0078] In this embodiment, the air deflector 40 is inclined downwards from front to back, meaning it guides air upwards and forwards. When the indoor unit 100 blows cold air into the room, the air deflector 40 guides the cold air upwards and then diffuses downwards within the room. This prevents large temperature differences in the vertical direction and avoids direct cold air blowing on the user, which could affect their health. The air deflector 40's angle can be adjusted according to different airflow types to meet different user needs, thereby improving the user experience.

[0079] In some embodiments of this utility model, such as Figure 4 As shown, multiple guide vanes 40 extend in the left and right directions, and the guide vanes 40 are set at an upward tilt from front to back.

[0080] In this embodiment, the air deflector 40 is inclined upwards from front to back, meaning it guides airflow forward and downwards. When the indoor unit 100 blows hot air into the room, the air deflector 40 guides the hot air downwards at an angle, allowing it to diffuse upwards within the room and preventing significant temperature differences in the vertical direction. The air deflector 40's angle can be adjusted according to different airflow types to meet varying user needs and improve the user experience.

[0081] In some embodiments of this utility model, multiple guide plates 40 extend in the left-right direction, some guide plates 40 are inclined downward from front to back, and other guide plates 40 are inclined upward from front to back.

[0082] In this embodiment, the air deflectors 40 are divided into two groups with different tilt directions. One group of air deflectors 40 is tilted downwards from front to back, guiding airflow forward and upwards. The other group of air deflectors 40 is tilted upwards from front to back, guiding airflow forward and downwards. By setting multiple air deflectors 40 with different tilt directions, the air guiding directions of the multiple air deflectors 40 are different, thereby enabling the indoor unit 100 of the air conditioner to deliver air in multiple directions, thus meeting different user airflow needs and improving the user experience.

[0083] Furthermore, in some embodiments of this utility model, the two sets of guide plates 40 are respectively a first guide plate group 410 and a second guide plate group 420. The guide plates 40 of the first guide plate group 410 are inclined downward from front to back, and the guide plates 40 of the first guide plate group 410 are inclined upward from front to back. The first guide plate group 410 is located above the second guide plate group 420.

[0084] 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. The first guide vane group 410 is located above the second guide vane group 420, 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, improving the air delivery angle and air delivery range of the air conditioner indoor unit 100, thereby improving the air delivery effect of the air conditioner indoor unit 100 and improving the user experience.

[0085] Furthermore, in some embodiments of this utility model, such as Figure 5 As shown, the two sets of guide vanes 40 are the first guide vane group 410 and the second guide vane group 420, respectively. The guide vanes 40 of the first guide vane group 410 are inclined downward from front to back, and the guide vanes 40 of the first guide vane group 410 are inclined upward from front to back. The first guide vane group 410 is located below the second guide vane group 420.

[0086] 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. The first guide vane group 410 is located below the second guide vane group 420, causing the airflow above to blow out diagonally downward and the airflow below to blow out diagonally upward. That is, the air conditioner indoor unit 100 converges and delivers air to the front side, and the airflow is concentrated to the middle position. The air delivery of the air conditioner indoor unit 100 is more concentrated, which increases the air delivery distance of the air conditioner indoor unit 100, thereby improving the air delivery effect of the air conditioner indoor unit 100 and improving the user experience.

[0087] In some preferred embodiments of this utility model, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit 100.

[0088] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the housing 10 includes an air inlet 70, which is located on the rear side of the housing 10.

[0089] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
