Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner and a front shell component. Background Technology

[0002] In related technologies, the air blown out by the air conditioner has a temperature difference with the indoor air to regulate the temperature of the indoor air. However, the airflow that is colder than the indoor air tends to sink because it is denser, while the airflow that is hotter than the indoor air tends to rise because it is less dense. This results in cold air blowing directly onto the legs or hot air blowing directly onto the head, creating a large temperature difference along the height of the room. This is not conducive to uniform indoor air temperature, resulting in a poor cooling and heating experience and poor comfort. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides an air conditioner that can improve temperature uniformity along the vertical direction of a room.

The crossbeam includes a first crossbeam with a vertically penetrating ventilation hole formed on the first crossbeam. The upstream air guide component includes an upstream air guide plate.

[0006] According to the embodiment of the present invention, the air conditioner is equipped with multiple upstream air guide plates that can swing up and down and are spaced apart vertically to change the angle between the airflow and the horizontal plane, so that the airflow blows upward or downward at an angle. Combined with the ventilation holes that are set on the first crossbeam and penetrate vertically, when the airflow passes through the crossbeam, the ventilation holes allow the airflow to pass through, thereby facilitating the upward flow of cold air or the downward flow of hot air. This allows the cold air to be blown to a higher height and the hot air to be blown to a lower area, improving the temperature uniformity in the vertical direction of the room and enhancing comfort.

[0091] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to a first aspect embodiment of the present invention will be described.

[0092] Combination Figures 1-3 The air conditioner 100 includes a front housing component 1 and an upstream air guide component 2. The front housing component 1 includes an air outlet frame 11 and a crossbeam component 12. The air outlet frame 11 includes a first air duct wall 111 and a second air duct wall 112. The first air duct wall 111 and the second air duct wall 112 both extend vertically and are spaced laterally to form an air outlet duct 113 between the first air duct wall 111 and the second air duct wall 112. The crossbeam component 12 is located between the first air duct wall 111 and the second air duct wall 112 and extends laterally. The crossbeam component 12 includes a first crossbeam 121, on which a vertically penetrating ventilation hole 1211 is formed. The upstream air guide component 2 includes an upstream air guide plate 21. The upstream air guide plates 21 are located on the upstream side of the crossbeam component 12 and are multiple plates spaced vertically. The upstream air guide plates 21 can swing up and down to guide air.

[0093] In the field of air conditioning technology, the main operating principle of an air conditioner is to regulate the indoor air temperature by utilizing the temperature difference between the blown-out air and the indoor air. When the air conditioner blows out air at a temperature lower than the indoor temperature, the cold air, due to its relatively higher density, will more easily sink downwards after entering the indoor space due to its own gravity. Conversely, when the air conditioner blows out air at a temperature higher than the indoor temperature, the hot air, with its lower density, will more easily rise.

[0094] Therefore, in cooling mode, cold air tends to blow directly onto the legs, causing noticeable discomfort; while in heating mode, hot air tends to blow directly onto the head, causing feelings of heat and stuffiness. Furthermore, due to the sinking of cold air and the rising of hot air, significant temperature differences are created along the vertical axis of the room, resulting in uneven air temperature at different heights and a poor overall cooling / heating experience, failing to provide a comfortable indoor environment.

[0095] In the technical solution of this application, by setting up multiple upstream air guide plates 21 that can swing up and down and are spaced apart vertically, the angle between the airflow and the horizontal plane is changed, so that the airflow blows upward or downward at an angle. Combined with the ventilation holes 1211 that are set on the first crossbeam 121 and penetrate vertically, when the airflow passes through the crossbeam 12, the ventilation holes 1211 can allow the airflow to pass through, thereby facilitating the upward flow of cold air or the downward flow of hot air, so that the cold air blows to a higher height and the hot air blows to a lower area, improving the temperature uniformity in the vertical direction of the room, reducing the direct blowing of airflow onto the human body, and improving comfort.

[0096] For example, such as Figure 4 As shown, in cooling mode, multiple upstream air guides 21, which can swing up and down and are spaced vertically, guide the cold air upwards, causing the cold air to flow obliquely upwards. When the cold air passes the crossbeam 12, the ventilation holes 1211 allow the cold air to pass through from bottom to top, reducing the obstruction to the oblique upward flow of the cold air. This allows the cold air to flow to a higher height instead of blowing directly at the human body, making the human body feel a strong cold air. Then the cold air gradually sinks and gradually mixes with the indoor air, so that the indoor air temperature surrounding the human body is at a comfortable cold air temperature, and the temperature difference in the vertical direction of the room is small, improving the comfort of the air conditioner 100 blowing cold air.

[0097] For example, such as Figure 5As shown, in heating mode, multiple upstream air guides 21, which can swing up and down and are spaced vertically, guide hot air downwards, causing the hot air to flow obliquely downwards. When the cold air passes the crossbeam 12, the ventilation holes 1211 allow the hot air to pass through from top to bottom, reducing the obstruction to the oblique downward flow of the hot air. This allows the hot air to flow to a lower area instead of blowing directly at the human body, making the human body feel strong hot air. Then the hot air gradually rises and gradually mixes with the indoor air, so that the indoor air temperature surrounding the human body is at a comfortable hot air temperature, and the temperature difference in the vertical direction of the room is small, improving the comfort of the air conditioner 100 blowing hot air.

[0098] Furthermore, the crossbeam 12 is located between the first air duct wall 111 and the second air duct wall 112 and extends laterally, serving to connect and support the first air duct wall 111 and the second air duct wall 112. This enhances the overall structural stability of the front shell component 1 and improves the deformation problem of the air outlet duct 113, especially when the vertical dimensions of the first air duct wall 111 and the second air duct wall 112 are large. The first crossbeam 121 has vertically penetrating ventilation holes 1211. Ventilation holes 1211 refer to holes through which airflow can pass without being filled or blocked, which is conducive to the upward movement of cold air and the downward movement of hot air, thereby improving the heat exchange effect. It is worth noting that the ventilation holes 1211 also allow airflow to pass through when the airflow is blowing horizontally, thereby balancing the airflow pressure above and below the crossbeam 12.

[0099] In the embodiments of this application, there is one or multiple crossbeam members 12 arranged at vertical intervals, and at least one crossbeam member 12 is a first crossbeam 121; the first air duct wall 111 and the second air duct wall 112 both extend vertically and are spaced laterally, wherein the lateral spacing can be completely spaced along the horizontal direction or approximately spaced along the horizontal direction.

[0100] In the embodiments of this application, the upstream air guide plate 21 is located on the upstream side of the crossbeam member 12. The "upstream side" refers to the side that the airflow passes through first relative to the air outlet direction of the air conditioner 100, that is, the air outlet airflow passes through the upstream air guide plate 21 first, and then passes through the crossbeam member 12.

[0101] In the embodiments of this application, the shape of the ventilation hole 1211 is not limited; for example, such as Figure 3 As shown, the ventilation holes 1211 can be square and arranged horizontally. The square shape is suitable for the shape of the crossbeam 12, which helps to increase the opening ratio. The ventilation holes 1211 can also be circular. Circular ventilation holes 1211 are relatively simple to process and have better ventilation effect. Of course, the ventilation holes 1211 can also be other polygonal shapes.

[0102] In some embodiments, see Figure 6In orthographic projection with the horizontal plane as the projection plane, the ratio of the total area of ​​the ventilation holes 1211 on the first crossbeam 121 to the area of ​​the first crossbeam 121 is greater than or equal to 50%. For example, the ratio of the total area of ​​the ventilation holes 1211 on the first crossbeam 121 to the area of ​​the first crossbeam 121 can be 50%, 60%, 70%, 80%, 90%, etc.

[0103] In the above technical solution, the ratio of the total area of ​​the ventilation holes 1211 on the first crossbeam 121 to the area of ​​the first crossbeam 121 is greater than or equal to 50%. This means that the ventilation holes 1211 occupy a large proportion of the area of ​​the first crossbeam 121, allowing more airflow to pass through the first crossbeam 121, reducing the resistance of the airflow (cold or hot air) at the first crossbeam 121, making the airflow in the air outlet duct 113 flow more smoothly, improving the air outlet efficiency of the air conditioner 100, thereby enabling faster indoor temperature regulation and improving comfort.

[0104] In some embodiments, see Figure 6 The first crossbeam 121 is provided with a plurality of ventilation holes 1211, which are spaced apart in the transverse direction. The transverse distance L1 between adjacent ventilation holes 1211 is less than the transverse dimension L2 of the ventilation hole 1211.

[0105] In the above technical solution, multiple ventilation holes 1211 are arranged at horizontal intervals, and the horizontal spacing between adjacent ventilation holes 1211 is smaller than the horizontal dimension of the ventilation holes 1211. This increases the ventilation area of ​​the ventilation holes 1211 on the first crossbeam 121, allowing airflow to pass more smoothly, reducing the resistance of airflow (cold or hot air) at the first crossbeam 121, and improving ventilation efficiency.

[0106] In some embodiments, the upper and / or lower surfaces of the first crossbeam 121 are formed to extend obliquely relative to the horizontal plane along the air outlet direction.

[0107] In the above technical solution, the upper and / or lower surfaces of the first crossbeam 121 extend at an angle relative to the horizontal plane along the air outlet direction. When the airflow is obliquely blowing, the angle of the upper / lower surfaces of the first crossbeam 121 is the same as or close to the angle of oblique blowing, which can reduce the resistance of airflow and improve ventilation efficiency. Of course, combined with the primary guidance of the upstream air guide plate 21, when the airflow passes through the obliquely extended surface of the first crossbeam 121, the upper / lower surfaces of the first crossbeam 121 can also be used to further guide the direction of airflow, thereby optimizing the cooling and / or heating effect.

[0108] For example, in cooling mode, the upstream air guide plate 21 tilts upward to guide cold air, and the upper / lower surfaces of the first crossbeam 121 can be set to tilt upward relative to the horizontal surface, so that the cold air flows further upward at an angle, allowing the cold air to flow to a higher height. Then the cold air gradually sinks and gradually mixes with the indoor air, thereby improving the heat transfer and mixing effect between the cold air and the indoor air, making the indoor temperature more uniform and optimizing the cooling effect. In heating mode, the upstream air guide plate 21 tilts downward to guide hot air, and the upper / lower surfaces of the first crossbeam 121 can be set to tilt upward relative to the horizontal surface, so that the hot air flows further downward at an angle, allowing the hot air to flow to a lower area. Then the hot air gradually rises and gradually mixes with the indoor air, thereby improving the heat transfer and mixing effect between the hot air and the indoor air, making the indoor temperature more uniform and optimizing the heating effect.

[0109] In the embodiments of this application, the upper surface and / or lower surface of the first crossbeam 121 is formed to extend obliquely relative to the horizontal plane along the air outlet direction. It can be that the upper surface or the lower surface of the first crossbeam 121 extends obliquely relative to the horizontal plane along the air outlet direction, or both the upper surface and the lower surface of the first crossbeam 121 extend obliquely relative to the horizontal plane along the air outlet direction. Of course, if both the upper and lower surfaces of the first crossbeam 121 extend obliquely relative to the horizontal plane along the air outlet direction, the air guiding effect is better and it is more conducive to improving the cooling and heating effect.

[0110] In some embodiments, see Figure 7 The air outlet duct 113 has at least one crossbeam 12 on each of its upper and lower sides at the vertical center plane S1. The upper and / or lower surfaces of the at least one crossbeam 12 above the vertical center plane S1 are shaped to extend downwards at an angle relative to the horizontal plane along the air outlet direction, while the upper and / or lower surfaces of the at least one crossbeam 12 below the vertical center plane S1 are shaped to extend upwards at an angle relative to the horizontal plane along the air outlet direction. It is worth noting that the crossbeam 12 here can be a first crossbeam 121, or it can be a second crossbeam 122 as described below. The vertical center plane S1 is a virtual plane that roughly divides the air outlet duct 113 into upper and lower parts in the vertical direction. For example, the air outlet duct 113 can be divided into three parts along the height direction, and the plane of the middle part can be understood as the vertical center plane S1.

[0111] In the above technical solution, the upper and / or lower surfaces of at least one crossbeam member 12 located above the height center plane S1 are formed to extend downwards at an angle relative to the horizontal plane along the air outlet direction. Thus, in the heating mode, the hot air located above the height center plane S1 of the air outlet duct 113 can be guided by the downwardly extending upper / lower surfaces of the crossbeam member 12 as it flows along the air outlet direction, allowing the hot air to flow to a lower area. Then, the hot air gradually rises and gradually mixes with the indoor air, thereby making the indoor air temperature surrounding the human body at a comfortable hot air temperature and the temperature difference in the height direction of the room small, improving the comfort of the air conditioner 100 blowing hot air.

[0112] In the above technical solution, the upper and / or lower surfaces of at least one crossbeam member 12 located below the height center plane S1 are formed to extend upwards at an angle relative to the horizontal plane along the air outlet direction. Thus, in the cooling mode, the cold air located below the height center plane S1 of the air outlet duct 113 can be guided by the upwardly extending upper / lower surfaces of the crossbeam member 12 as it flows along the air outlet direction, allowing the cold air to flow to a higher height. Then, the cold air gradually sinks and gradually mixes with the indoor air, thereby making the indoor air temperature surrounding the human body at a comfortable cold air temperature and the temperature difference in the vertical direction of the room small, improving the comfort of the air conditioner 100 blowing cold air.

[0113] In some embodiments, combined with Figure 8 and Figure 9 The air conditioner 100 also includes an air outlet grille 3, which is located on the downstream side of the crossbeam 12. The air outlet grille 3 includes horizontal bars 31, which extend laterally and are a plurality of bars spaced vertically. The upper and / or lower surfaces of at least one horizontal bar 31 are formed to extend obliquely relative to the horizontal plane in the air outlet direction.

[0114] In the above technical solution, by setting inclined horizontal bars 31, the tilt angle and number of horizontal bars 31 can be adjusted according to different airflow requirements. For example, when a larger air volume and a longer air delivery distance are required, the tilt angle of the horizontal bars 31 can be appropriately reduced or the number of inclined horizontal bars 31 can be increased to reduce airflow resistance; when a smaller air volume and a more uniform airflow distribution are required, the tilt angle of the horizontal bars 31 can be appropriately increased or the number of inclined horizontal bars 31 can be reduced to increase airflow diffusion; in addition, the inclined horizontal bars 31 can increase the overall structural strength of the air outlet grille 3, making it more stable and reliable under the pressure of airflow and its own weight, reducing the possibility of deformation or damage to the air outlet grille 3 during use, thereby improving the reliability of the air conditioner 100.

[0115] In the above technical solution, the upper and / or lower surfaces of the horizontal grid 31 extend at an angle relative to the horizontal plane along the air outlet direction. When the airflow is obliquely blowing, the angle of the upper / lower surface of the horizontal grid 31 is consistent with or close to the angle of oblique blowing, which can reduce the resistance of airflow, reduce the turbulence and resistance of airflow at the horizontal grid 31, and improve ventilation efficiency. Of course, combined with the primary guidance of the upstream air guide plate 21, when the airflow passes through the upper / lower surface of the horizontal grid 31, the upper / lower surface of the horizontal grid 31 can also be used to further guide the direction of airflow, thereby optimizing the cooling and / or heating effect.

[0116] For example, in cooling mode, the upstream air guide plate 21 is tilted upward to guide cold air, and the upper / lower surfaces of the horizontal grating 31 can be set to tilt upward, so that the cold air can flow further upward at an angle when it flows through the air outlet grille 3, allowing the cold air to flow to a higher height. Then the cold air gradually sinks and gradually mixes with the indoor air, thereby improving the heat transfer and mixing effect between the cold air and the indoor air, making the indoor temperature more uniform and optimizing the cooling effect. In heating mode, the upstream air guide plate 21 is tilted downward to guide hot air, and the upper / lower surfaces of the horizontal grating 31 can be set to tilt downward, so that the hot air can flow further downward at an angle when it flows through the air outlet grille 3, allowing the hot air to flow to a lower area. Then the hot air gradually rises and gradually mixes with the indoor air, thereby improving the heat transfer and mixing effect between the hot air and the indoor air, making the indoor temperature more uniform and optimizing the heating effect.

[0117] In the embodiments of this application, the above embodiments can be combined, that is, the upper surface and / or lower surface of the first crossbeam 121 is formed to extend obliquely relative to the horizontal plane along the air outlet direction. Thus, a three-stage air guiding structure can be formed: in the airflow direction, the upstream air guide plate 21 is the first stage guide, the upper / lower surface of the first crossbeam 121 is the second stage guide, and the upper / lower surface of the horizontal grid 31 is the third stage guide. This forms a multi-stage air guiding structure that gradually guides the airflow to change the angle with the horizontal plane, thereby reducing the problem of excessive airflow resistance caused by excessive change in air guiding angle, and the generation of turbulence and noise at the air guiding part.

[0118] In some embodiments, see Figure 8 and Figure 9 The air outlet duct 113 has at least one horizontal grating 31 on the upper and lower sides of the vertical height center plane S1. The upper and / or lower surfaces of the at least one horizontal grating 31 above the height center plane S1 are formed to extend downwards at an angle relative to the horizontal plane along the air outlet direction. The upper and / or lower surfaces of the at least one horizontal grating 31 below the height center plane S1 are formed to extend upwards at an angle relative to the horizontal plane along the air outlet direction.

[0119] In the above technical solution, the upper and / or lower surfaces of at least one horizontal grating 31 located above the central plane S1 are formed to extend downwards at an angle relative to the horizontal plane along the air outlet direction. Thus, in the heating mode, the hot air located above the central plane S1 of the air outlet duct 113 can be guided by the downwardly extending upper / lower surfaces of the horizontal grating 31 as it flows along the air outlet direction, allowing the hot air to flow to a lower area. Then, the hot air gradually rises and gradually mixes with the indoor air, the hot air velocity decreases and the hot air temperature approaches the human comfort temperature, improving the comfort of the air conditioner 100 blowing hot air.

[0120] In the above technical solution, the upper and / or lower surfaces of at least one horizontal grating 31 located below the height center plane S1 are formed to extend upwards at an angle relative to the horizontal plane along the air outlet direction. Thus, in the cooling mode, the cold air located below the height center plane S1 of the air outlet duct 113 can be guided by the upper / lower surfaces of the horizontal grating 31 as it flows along the air outlet direction, allowing the cold air to flow to a higher height. Then, the cold air gradually sinks and gradually mixes with the indoor air, the cold air velocity decreases and the cold air temperature approaches the human comfort temperature, improving the comfort of the air conditioner 100 blowing cold air.

[0121] In some embodiments, see Figure 10 All the horizontal bars 31 are divided into multiple groups arranged sequentially from top to bottom. Each group includes one or more adjacent bars arranged at the same tilt angle. The horizontal bars 31 located above the central height plane S have a gradually increasing downward tilt angle relative to the horizontal plane S from bottom to top, while the horizontal bars 31 located below the central height plane S have a gradually increasing upward tilt angle relative to the horizontal plane S from top to bottom. Thus, the horizontal bars 31 with different tilt angles guide the airflow to diffuse at different angles and speeds, increasing the mixing degree between the airflow and the surrounding air, allowing the airflow to exchange heat more fully with the indoor air, and improving the cooling or heating efficiency of the air conditioner 100.

[0122] In some embodiments, see Figure 10 and Figure 11 The difference in tilt angle between adjacent groups of horizontal bars 31 is 5°-15°. For example, the difference in tilt angle between adjacent groups of horizontal bars 31 can be 5°, 7°, 9°, 10°, 11°, 13°, 15°, etc.

[0123] For example, above the central height plane S1, there are 7 horizontal bars 31, arranged in pairs from top to bottom, with the one closest to the central height plane S forming one group. The first group of horizontal bars 31 from the top has a downward tilt angle of 30° relative to the horizontal plane, the second group has a downward tilt angle of 20°, the third group has a downward tilt angle of 10°, and the horizontal bar 31 closest to the central height plane S is the fourth group from the top with a downward tilt angle of 0° relative to the horizontal plane; below the central height plane S1, there are 9... There are two horizontal bars 31, arranged in pairs from bottom to top. The bar closest to the center plane S is in one group. The first group of horizontal bars 31 from the bottom has a downward tilt angle of 40° relative to the horizontal plane, the second group has a downward tilt angle of 30° relative to the horizontal plane, the third group has a downward tilt angle of 20° relative to the horizontal plane, the fourth group has a downward tilt angle of 10° relative to the horizontal plane, and the bar closest to the center plane S is in the fifth group from the bottom with a downward tilt angle of 0° relative to the horizontal plane.

[0124] In the above technical solution, the tilt angle difference between adjacent groups of horizontal bars 31 is within the range of 5°-15°, thus providing multiple possibilities for airflow adjustment. When the difference is small (e.g., close to 5°), the change in airflow direction is relatively gentle, making it suitable for scenarios with high requirements for airflow stability, small spaces, or sensitivity to airflow changes; when the difference is large (e.g., close to 15°), the airflow guiding effect is more obvious, and the airflow direction can be changed quickly, thus adapting to occasions requiring a larger airflow adjustment range.

[0125] In some embodiments, see Figure 12 The air outlet grille 3 is located on the front side of the air conditioner 100. The length direction of the air outlet grille 3 is vertical, and the width direction is horizontal. The width of the air outlet grille 3 in the horizontal direction is greater than 70% of the width of the air conditioner 100 in the horizontal direction. For example, the ratio of the width of the air outlet grille 3 in the horizontal direction to the width of the air conditioner 100 in the horizontal direction can be 70%, 75%, 80%, 85%, 90%, etc. This means that the area of ​​the air outlet is relatively large. The larger air outlet area increases the airflow through the air outlet grille 3 per unit time, thereby improving the cooling, heating, or ventilation effect of the air conditioner, and the air conditioner 100 can adjust the indoor temperature more quickly. In addition, the wide air outlet grille 3 can make the air supply direction more dispersed, covering a wider indoor space, reducing the difference in indoor temperature or air quality, and improving the comfort of using the air conditioner.

[0126] It is worth noting that the length direction of the air outlet grille 3 is vertical, and the width direction of the air outlet grille 3 is horizontal. The width of the air outlet grille 3 in the horizontal direction is greater than 70% of the width of the air conditioner 100 in the horizontal direction. This provides a design basis for realizing multiple air outlet modes of the air conditioner 100.

[0127] For example, the air outlet grille 3 can be designed as a segmented air outlet grille 3 along the central plane S1 of the height, thereby allowing independent control of the upper and lower sections according to different air outlet needs. For instance, during summer cooling, the lower section of the air outlet grille 3 along the central plane S1 of the height can be used to allow cold air to flow to a higher height, improving the comfort of the air conditioner 100 blowing cold air; during winter heating, the upper section of the air outlet grille 3 along the central plane S1 of the height can be used to allow hot air to flow to a lower area, improving the comfort of the air conditioner 100 blowing hot air.

[0128] For example, multiple sets of air guide plates can be set upstream of the air outlet grille 3, which can guide the air outlet direction to different positions according to the user's actual needs, thereby improving the user comfort of the air conditioner 100.

[0129] In some embodiments, combined with Figure 12 and Figure 13 The air outlet grille 3 also includes vertical grille bars 32, which extend vertically and are multiple bars spaced horizontally. The horizontal spacing L3 between adjacent vertical grille bars 32 is less than 1 / 3 of the vertical spacing L4 between adjacent horizontal grille bars 31. The vertical grille bars 32 protrude downstream of the horizontal grille bars 31. Therefore, the vertical grille bars 32 are spaced relatively close together, and since they protrude downstream of the horizontal grille bars 31, the horizontal grille bars 31 are hidden behind the vertical grille bars 32. This makes it difficult for users to observe the horizontal grille bars 31, but makes it easy to observe the longer vertical grille bars 32, which are a major feature of the air conditioner 100. The smaller horizontal spacing L3 of the vertical grille bars 32 effectively prevents larger foreign objects from entering the air conditioner, protecting internal components such as the heat exchanger and fan from damage and extending the service life of the air conditioner.

[0130] In the embodiments of this application, the specific shapes of the vertical grid strips 32 and the horizontal grid strips 31 are not limited, such as rectangular, trapezoidal, circular cross-sections, etc., as long as they are easy to process and manufacture and have relatively stable performance in guiding airflow.

[0131] In the embodiments of this application, the horizontal spacing L3 refers to the horizontal distance between the center lines of two adjacent vertical bars 32; the vertical spacing L4 refers to the vertical distance between the center lines of two adjacent horizontal bars 31.

[0132] In some embodiments, combined with Figure 14 , Figure 15 and Figure 16The air conditioner 100 also includes a downstream air guide component 4, which includes a downstream air guide plate 41. The downstream air guide plate 41 is located on the downstream side of the crossbeam 12. The downstream air guide plate 41 extends vertically and is arranged in multiple units at intervals along the transverse direction. The downstream air guide plate 41 is pivotally engaged with the first crossbeam 121 so that it can rotate relative to the air outlet frame 11 around the vertical axis S2 that extends vertically.

[0133] In the above technical solution, the downstream air guide plate 41 is pivotally coupled with the first crossbeam 121, and can rotate relative to the air outlet frame 11 around the vertically extending vertical axis S2. This allows the airflow to be guided and changed in the left-right tilt angle, enabling the air conditioner 100 to sweep air left and right to meet the air conditioning needs of different areas indoors, thus improving the flexibility and comfort of the air conditioner 100. The pivotal coupling method ensures the smoothness and stability of the air guide plate during rotation. Furthermore, when combined with the vertical air guiding effect of the upstream air guide plate 21, the air conditioner 100 achieves three-dimensional angle air outlet adjustment. The airflow, guided by the upstream air guide plate 21 and the downstream air guide plate 41, achieves greater angle and range adjustment, which is conducive to achieving a comprehensive airflow effect and improving the cooling or heating efficiency of the air conditioner 100.

[0134] In some embodiments, combined with Figure 14 , Figure 15 and Figure 16 The downstream air guide plate 41 has a first pivot shaft 411 extending vertically, and the downstream end of the first crossbeam 121 has a retaining shaft portion 1212. The retaining shaft portion 1212 defines a first shaft hole 12121 that opens toward the first air duct wall 111 or the second air duct wall 112. The first pivot shaft 411 is inserted into the first shaft hole 12121 from the open side of the first shaft hole 12121 to pivotally engage with the first crossbeam 121.

[0135] In the above technical solution, the first pivot shaft 411 is inserted into the first shaft hole 12121 through its open side to achieve pivotal engagement with the first crossbeam 121. This simple and convenient installation method allows for quick and accurate installation of the downstream air guide plate 41 onto the first crossbeam 121 during the assembly of the air conditioner 100, improving production efficiency. The locking part 1212 defines the first shaft hole 12121, providing good positioning and support for the first pivot shaft 411. After the first pivot shaft 411 is inserted into the first shaft hole 12121, it can stably pivot with the first crossbeam 121, reducing the possibility of the downstream air guide plate 41 shaking or falling off during rotation. Since the first pivot shaft 411 and the first shaft hole 12121 are detachably engaged, maintenance difficulty and cost are reduced, improving the maintainability of the air conditioner 100.

[0136] In some embodiments, see Figure 17The downstream air guide component 4 includes a plurality of linkage units 40 arranged in a transverse direction; each linkage unit 40 includes a plurality of downstream air guide plates 41 arranged adjacent to each other in a transverse direction, and each linkage unit 40 also includes a first link 42 connected to all the downstream air guide plates 41 in the same linkage unit 40, and a first drive motor 43 connected to one of the downstream air guide plates 41 in the linkage unit 40.

[0137] In the above technical solution, multiple downstream air guide plates 41 in the same linkage unit 40 are connected by a first connecting rod 42, and one of the downstream air guide plates 41 is driven to move by a first drive motor 43, thereby driving all the downstream air guide plates 41 in the entire linkage unit 40 to move synchronously. Thus, controlling one drive motor can realize the linkage adjustment of multiple downstream air guide plates 41, and can ensure the consistency of multiple downstream air guide plates 41 when adjusting the angle, so that the airflow guidance in the same linkage unit 40 is more coordinated and more consistent.

[0138] Furthermore, the use of multiple linkage units 40 reduces the number of drive motors required and enables independent control of different linkage units 40. Compared to equipping each downstream air guide plate 41 with a separate drive motor, this reduces control and production costs. At the same time, the structure of the first linkage 42 is relatively simple and the linkage is reliable, making the structure of the downstream air guide component 4 more compact.

[0139] In the embodiments of this application, the downstream air guide component 4 includes a plurality of linkage units 40 arranged laterally. The linkage units 40 can be 2, 3, 4, 5, etc. The number of downstream air guide plates 41 included in each linkage unit 40 is not limited, for example, it can be 2, 3, 4, 5, etc.

[0140] In some embodiments, combined with Figure 16 and Figure 17 The upstream of the first air duct wall 111 is connected to the volute tongue. The linkage unit 40 consists of two units, namely the first linkage unit 40a and the second linkage unit 40b, which are arranged in the direction from the first air duct wall 111 to the second air duct wall 112. All the downstream air guide plates 41 in the downstream air guide component 4 are evenly distributed in the transverse direction. The number of downstream air guide plates 41 included in the first linkage unit 40a is less than the number of downstream air guide plates 41 included in the second linkage unit 40b.

[0141] In the above technical solution, since the upstream of the first air duct wall 111 is connected to the volute tongue, and the first linkage unit 40a is closer to the first air duct wall 111 than the second linkage unit 40b, the airflow is more likely to flow towards the first linkage unit 40a. By setting the number of downstream air guide components 4 in the first linkage unit 40a to be less than the number of downstream air guide plates 41 included in the second linkage unit 40b, more airflow is guided towards the second linkage unit 40b, thereby balancing the airflow through the first linkage unit 40a and the second linkage unit 40b, improving the uniformity of airflow on both sides, and enhancing the user experience.

[0142] In the embodiments of this application, the two linkage units 40 can be controlled independently, so that the downstream air guide plate 41 in the first linkage unit 40a and the downstream air guide plate 41 in the second linkage unit 40b can guide the air in the same direction or in different directions. When they guide the air to the two sides that are far apart from each other, a larger air delivery angle and range can be obtained. When they guide the air to the directions that are close to each other, concentrated air delivery can be achieved. When they guide the air to the same direction, the airflow can be concentrated and sent out in a certain direction.

[0143] In some embodiments, combined with Figure 17 , Figure 18 and Figure 24 The air outlet frame 11 includes an upper mounting portion 114 located above the downstream air guide plate 41 and a lower mounting portion 115 located below the downstream air guide plate 41. All the first drive motors 43 are mounted on the upper mounting portion 114 and are spaced apart in the lateral direction. The lower end of the downstream air guide plate 41 is pivotally engaged with the lower mounting portion 115.

[0144] In the above technical solution, all the first drive motors 43 are mounted on the upper mounting part 114 and spaced laterally, which makes the motor mounting positions relatively concentrated, facilitating the installation, maintenance and management of the motors. At the same time, mounting all the first drive motors 43 on the upper mounting part 114 also helps to reduce the possibility of motor failure caused by condensate water from the air conditioner 100 submerging or splashing onto the first drive motors 43, thereby improving the reliability of the air conditioner 100.

[0145] In addition, the air outlet frame 11 is provided with an upper mounting part 114 and a lower mounting part 115, which are respectively used to install the first drive motor 43 and pivotally cooperate with the downstream air guide plate 41. The upper mounting part 114 bears the weight of the first drive motor 43 and the force generated during operation, while the lower mounting part 115 bears the weight of the downstream air guide plate 41 and the force generated during rotation. The two cooperate with each other to ensure the stability and reliability of the air outlet frame 11 during operation and reduce vibration and noise problems caused by structural instability.

[0146] In the embodiments of this application, it is of course not limited to this. Alternatively, all the first drive motors 43 may be mounted on the lower mounting portion 115 and spaced laterally, with the upper end of the downstream air guide plate 41 pivotally engaged with the upper mounting portion 114.

[0147] In some embodiments, combined with Figure 20 and Figure 21 The crossbeam component 12 also includes a second crossbeam 122, which is vertically spaced from the first crossbeam 121. The front shell component 1 also includes a pressure plate 13, which is located downstream of the second crossbeam 122. The pressure plate 13 and the second crossbeam 122 together define a second shaft hole 1221. The downstream air guide plate 41 has a second pivot shaft 412 extending vertically, which is rotatably disposed in the second shaft hole 1221.

[0148] In the above technical solution, by setting the second crossbeam 122 and the first crossbeam 121 to be vertically spaced apart, the overall structural strength and stability of the air outlet frame 11 are increased. The second crossbeam 122 and the first crossbeam 121 jointly bear the weight of the downstream air guide plate 41 and other components and the force generated during operation, thereby enhancing the rotational stability of the downstream air guide plate 41 and preventing the downstream air guide plate 41 from shaking or falling off during use.

[0149] In addition, the pressure plate 13 is located on the downstream side of the second crossbeam 122, and together with the second crossbeam 122, defines the second shaft hole 1221. The second pivot shaft 412 is rotatably located in the second shaft hole 1221, so that the downstream air guide plate 41 can rotate flexibly around the second pivot shaft 412, thereby facilitating the adjustment of the air outlet angle and improving the rotation flexibility and reliability of the downstream air guide plate 41.

[0150] In some embodiments, combined with Figure 21 and Figure 22 The air conditioner 100 also includes a protective net 5, which is located on the upstream side of the crossbeam 12 and on the downstream side of the upstream air guide plate 21; the upstream side of the second crossbeam 122 is provided with a net support 14 that cooperates with the protective net 5 for limiting.

[0151] In the above technical solution, the protective net 5 is located on the upstream side of the crossbeam 12 and downstream of the upstream air guide plate 21, which meets the safety requirements and can block foreign objects from entering the air conditioner 100 to a certain extent, preventing these foreign objects from damaging the fan, heat exchanger and other components inside the air conditioner 100 and extending the service life of the air conditioner 100; the upstream side of the second crossbeam 122 is provided with a net bracket 14 that cooperates with the protective net 5 to limit the air outlet resistance, and the net bracket 14 limits and supports the protective net 5, thereby improving the installation stability and reliability of the protective net 5.

[0152] In some embodiments, combined with Figure 15 and Figure 16 The air conditioner 100 also includes a protective net 5, which is located on the upstream side of the crossbeam 12 and downstream of the upstream air guide plate 21; the upstream end of the first crossbeam 121 is provided with a mesh clamping part 1213 that cooperates with the protective net 5 for limiting.

[0153] In the above technical solution, the protective net 5 can prevent personnel from accidentally contacting the internal rotating parts (such as the fan) during the operation of the air conditioner 100, avoiding personal injury and improving the safety of the air conditioner 100. The upstream end of the first crossbeam 121 is provided with a net clamping part 1213 that cooperates with the protective net 5. The net clamping part 1213 limits the position of the protective net 5, so that the position of the protective net 5 is fixed and reliable, and it will not move or fall off due to airflow impact or other external forces, thus ensuring the normal operation of the equipment.

[0154] In some embodiments, combined with Figure 15 , Figure 16 , Figure 21 and Figure 22 The air conditioner 100 also includes a protective net 5, which is located on the upstream side of the crossbeam 12 and on the downstream side of the upstream air guide plate 21; the upstream side of the second crossbeam 122 is provided with a net support 14 that cooperates with the protective net 5 for limiting, and the upstream end of the first crossbeam 121 is provided with a net clamping part 1213 that cooperates with the protective net 5 for limiting.

[0155] In the above technical solution, a net support 14 is provided on the upstream side of the second crossbeam 122, and a net clamping part 1213 is provided at the upstream end of the first crossbeam 121. The net support 14 and the net clamping part 1213 together limit and support the protective net 5, thereby ensuring that the protective net 5 will not be displaced or shaken due to airflow during the operation of the air conditioner 100, improving the installation stability and reliability of the protective net 5, and reducing the air outlet resistance.

[0156] In the embodiments of this application, the form of the mesh support 14 and the mesh clamping part 1213 is not limited. For example, it can be a simple groove structure, in which the mesh wires of the protective mesh 5 are inserted into the groove to achieve positioning; the mesh clamping part 1213 is an elastic buckle structure, which clamps the mesh wires of the protective mesh 5 by the elastic deformation of the buckle.

[0157] In some embodiments, combined with Figure 15 , Figure 16 , Figure 23 and Figure 24The mesh section 1213 includes a first locking section 12131, a second locking section 12132, and a third locking section 12133 arranged laterally. The first locking section 12131 defines a first locking hole 12131a that opens toward the first air duct wall 111. The second locking section 12132 defines a second locking hole 12132a that opens toward the second air duct wall 112. The third locking section 12133 defines a third locking hole 12133a that opens toward the upstream side. The protective mesh 5 includes a plurality of vertical mesh wires 51 that extend vertically and are spaced laterally. The vertical mesh wires 51 include a first mesh wire 511 that cooperates with the first locking hole 12131a, a second mesh wire 512 that cooperates with the second locking hole 12132a, and a third mesh wire 513 that cooperates with the third locking hole 12133a.

[0158] In the above technical solution, the first locking part 12131, the second locking part 12132, and the third locking part 12133 cooperate with the first mesh wire 511, the second mesh wire 512, and the third mesh wire 513 respectively, thereby achieving multi-directional limiting of the protective net 5. This makes the fixing of the protective net 5 more reliable and prevents it from moving or falling off due to airflow impact or other external forces. The mesh locking part 1213 adopts a structure with multiple locking parts, which cooperate with multiple mesh wires of the protective net 5 to form a stable limiting system, improving the stability of the entire structure and enabling it to withstand greater external forces. The cooperation of multiple locking parts and mesh wires also ensures accurate installation of the protective net 5, improving the installation accuracy of the protective net 5.

[0159] In some embodiments, the combination of 18 and Figure 19 The air outlet frame 11 includes an upper limit part 116 located at the upper end of the protective net 5 and a lower limit part 117 located at the lower end of the protective net 5. The upper end of the protective net 5 has a mesh wire 52, which cooperates with the upper limit part 116 to restrict the protective net 5 from moving downward or up and down. The lower end of the protective net 5 has a lower mesh wire 53, which cooperates with the lower limit part 117 to restrict the protective net 5 from moving upward or up and down.

[0160] In the above technical solution, the cooperation between the upper limit part 116 and the lower limit part 117 with the mesh wire 52 and the lower mesh wire 53 respectively can effectively restrict the movement of the protective net 5 in the vertical direction, prevent the protective net 5 from shifting in the vertical direction during the operation of the air conditioner 100, and improve the installation stability of the protective net 5. In addition, the mesh clamping part 1213 on the first crossbeam 121 cooperates with the limiting position of the protective net 5, so that the protective net 5 has at least three fixed positions in the height direction, thereby making the protective net 5 firmly fixed in the air outlet frame 11. Especially when the protective net 5 is long in the height direction, the fixed positions of the protective net 5 play a key role in the vertical support of the protective net 5.

[0161] In some embodiments, see Figure 22 and Figure 23 The front shell component 1 also includes a mesh support 14, which is vertically spaced from the first crossbeam 121, and the protective mesh 5 is limited and matched with the mesh support 14.

[0162] In the above technical solution, the mesh support 14 and the first crossbeam 121 are arranged vertically at intervals, and the upstream end of the first crossbeam 121 is provided with a mesh clamping part 1213 that cooperates with the protective mesh 5 for limiting. The protective mesh 5 also cooperates with the mesh support 14 for limiting. Thus, the mesh support 14 and the mesh clamping part 1213 jointly limit and support the protective mesh 5, thereby ensuring that the protective mesh 5 will not be displaced or shaken due to airflow during the operation of the air conditioner 100, thus improving the installation stability and reliability of the protective mesh 5.

[0163] In the embodiments of this application, the location of the mesh support 14 is not limited. For example, the mesh support 14 can be set on both sides of the air outlet frame 11. The specific form of the limiting cooperation between the protective net 5 and the mesh support 14 is not limited. For example, it can be a slot-snap type limiting cooperation, a magnetic type limiting cooperation, etc.

[0164] In some embodiments, combined with Figure 20 and Figure 21 The crossbeam component 12 also includes a second crossbeam 122, which is located downstream of the mesh support 14. The front shell component 1 also includes a pressure plate 13, which is located downstream of the second crossbeam 122. The pressure plate 13 and the second crossbeam 122 together define a second shaft hole 1221. See also Figure 14 The air conditioner 100 also includes a downstream air guide component 4, which includes a downstream air guide plate 41. The downstream air guide plate 41 is located on the downstream side of the crossbeam 12. The downstream air guide plates 41 extend vertically and are arranged in multiple units at intervals along the transverse direction. The downstream air guide plate 41 has a second pivot shaft 412 extending vertically. Figure 20 and Figure 21 The second pivot shaft 412 is rotatably disposed in the second shaft hole 1221 so that it can rotate relative to the air outlet frame 11 about the vertical axis S2 extending vertically.

[0165] In the above technical solution, the crossbeam component 12 also includes a second crossbeam 122. The second crossbeam 122 and the pressure plate 13 together define the second shaft hole 1221, providing stable installation and rotation support for the second pivot shaft 412 of the downstream air guide plate 41. At the same time, the second crossbeam 122 also integrates a mesh bracket 14, which plays a limiting role for the protective mesh 5, thereby improving the structural compactness of the front shell component 1. The pressure plate 13 is located on the downstream side of the second crossbeam 122 and together with the second crossbeam 122 defines the second shaft hole 1221. The second pivot shaft 412 is rotatably disposed in the second shaft hole 1221, so that the downstream air guide plate 41 can rotate flexibly around the second pivot shaft 412, thereby facilitating the adjustment of the air outlet angle and improving the rotational flexibility and reliability of the downstream air guide plate 41.

[0166] In some embodiments, combined with Figure 25 and Figure 26 The upstream air guide plate 21 is pivotally connected to the air outlet frame 11 so that it can rotate relative to the air outlet frame 11 about the horizontal axis S3 extending laterally. The upstream air guide component 2 also includes a second link 22, a second drive motor 23 and a transmission mechanism 24. The second link 22 extends vertically and is connected to multiple upstream air guide plates 21 so as to drive multiple upstream air guide plates 21 to swing up and down synchronously. The second drive motor 23 is installed on the upper part of the air outlet frame 11 and is connected to the upper end of the second link 22 through the transmission mechanism 24 so as to drive the second link 22 to move vertically.

[0167] In the above technical solution, multiple upstream air guide plates 21 are connected by a second connecting rod 22, and the second driving motor 23 and transmission mechanism 24 drive the second connecting rod 22 to move, realizing the synchronous up-and-down swing of multiple upstream air guide plates 21. This ensures the consistency of movement of each air guide plate, makes the air outlet direction more stable, and improves the cooling or heating effect of the air conditioner 100.

[0168] In the embodiments of this application, the specific form of the transmission mechanism 24 is not limited. For example, the transmission mechanism 24 can be a gear and rack transmission, wherein the output shaft of the second drive motor 23 is connected to the gear, and a rack is provided on the transmission mechanism 24. The gear meshes with the rack to convert the rotational motion of the motor into the vertical linear motion of the rack. The rack and the second connecting rod 22 can slide in the horizontal direction to pull the second connecting rod 22 up and down. Alternatively, the transmission mechanism 24 can also be a lead screw and nut transmission, etc., which will not be elaborated here.

[0169] In some embodiments, see Figure 27Multiple first crossbeams 121 are arranged at vertical intervals. Since the first crossbeams 121 are located between the first air duct wall 111 and the second air duct wall 112 and extend laterally, the arrangement of multiple first crossbeams 121 at vertical intervals can significantly improve the structural strength of the air outlet frame 11. Especially when the length of the air outlet frame 11 is long, the vertically spaced arrangement of the first crossbeams 121 enables it to withstand greater external forces and vibrations in the length direction, reducing the risk of deformation and damage to the air outlet frame 11 during long-term use and extending the service life of the air conditioner 100.

[0170] In addition, with the ventilation holes 1211 provided on the first crossbeam 121 that run vertically through it, when the airflow passes through the crossbeam 12, the ventilation holes 1211 allow the airflow to pass through, which facilitates the upward flow of cold air or the downward flow of hot air. This allows the cold air to be blown to a higher height and the hot air to be blown to a lower area, reducing direct blowing on the human body, improving the temperature uniformity in the vertical direction of the room, and improving the air supply comfort of the air conditioner 100.

[0171] In some embodiments, see Figure 3 The first crossbeam 121 and the air outlet frame 11 are integrated components.

[0172] In the above technical solution, since the first crossbeam 121 and the air outlet frame 11 are integrally formed, the overall structure of the front shell component 1 is more robust, capable of withstanding greater external forces and vibrations, thus improving the reliability of the air conditioner 100. The integrated molding process can reduce assembly steps, lower production costs, and improve production efficiency.

[0173] In some embodiments, the first crossbeam 121 and the air outlet frame 11 are separate components but are assembled together.

[0174] In the above technical solution, the first crossbeam 121 and the air outlet frame 11 can be manufactured separately, which facilitates manufacturing according to different needs, such as using different materials and structural forms, to meet different performance requirements. When the first crossbeam 121 or the air outlet frame 11 is damaged, it can also be repaired or replaced individually without replacing the entire component, thus reducing maintenance costs.

[0175] Combination Figures 1-3 According to a second aspect embodiment of the present invention, the front shell component 1 includes an air outlet frame 11 and a crossbeam 12. The air outlet frame 11 includes a first air duct wall 111 and a second air duct wall 112. The first air duct wall 111 and the second air duct wall 112 both extend vertically and are spaced laterally to form an air outlet duct 113 between the first air duct wall 111 and the second air duct wall 112. The crossbeam 12 is disposed between the first air duct wall 111 and the second air duct wall 112 and extends laterally. The crossbeam 12 includes a first crossbeam 121, on which a vertically penetrating ventilation hole 1211 is formed.

[0176] According to the front shell component 1 of the second aspect of the present invention, the crossbeam 12 is disposed between the first air duct wall 111 and the second air duct wall 112, which can enhance the overall structural stability of the air outlet frame 11 and reduce the risk of deformation and damage to the air outlet frame 11 under the impact of airflow or external force. The first crossbeam 121 is disposed between the first air duct wall 111 and the second air duct wall 112, and a vertically penetrating ventilation hole 1211 is formed on the first crossbeam 121. The ventilation hole 1211 allows the airflow to pass through vertically, thereby improving the temperature uniformity along the vertical direction. It also helps to balance the airflow pressure above and below the crossbeam 12, which helps to reduce airflow turbulence and improve air outlet efficiency. In addition, the ventilation hole 1211 on the first crossbeam 121 reduces the manufacturing material of the first crossbeam 121 and saves manufacturing costs.
