Description

Technical Field

[0001] The invention relates to an air guide device of an air conditioner and the air conditioner. Background Art

[0002] With the improvement of living standards, users' requirements for air conditioning cooling and heating comfort and air conditioning appearance and clearance are gradually increasing. Currently, the air outlet of the indoor unit of household wall-mounted air conditioners is usually equipped with an air deflector, and the common types of air deflectors include single air deflector and double air deflector structures.

[0003] While existing air deflectors can guide airflow, they suffer from the following drawbacks: They have little directing effect on airflow. During cooling, the cold air blows directly onto people, causing poor comfort. During heating, they cannot quickly raise the room temperature, resulting in poor comfort. Furthermore, the airflow guidance process results in significant resistance losses, leading to high costs. Summary of the Invention

[0004] In order to overcome the defects of the prior art, the present invention provides an air guide device for an air conditioner which can improve the comfort level during cooling and heating.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An air guide device for an air conditioner includes an air guide assembly, which is arranged at the air outlet of the air conditioner and is part of the appearance of the air conditioner. The air guide assembly includes an air guide plate and air guide ribs, and the air guide ribs are arranged at the air outlet of the air guide surface of the air guide plate. The angle between the height direction of the air guide rib and the air guide surface is α, 90°<α<180°, and the height of the air guide rib is 1-2mm.

[0007] The present invention: the air guide ribs are arranged on the air guide surface of the air guide plate and are located at the air outlet of the air guide surface. The angle between the air guide surface and the air guide ribs in the height direction is α, 90°<α<180°, and the height of the air guide ribs is 1-2mm. The special structure of the air guide ribs can achieve farther air supply and avoid the Coanda effect that causes cold wind to blow on people.

[0008] The air guide device of the air conditioner described above has an air guide plate with an outwardly convex air guide surface, and the air guide ribs are arranged at the air outlet of the outwardly convex air guide surface. This arrangement improves the air guide plate's airflow diversion effect, and the air guide ribs can achieve a longer air flow, guiding the airflow in the desired direction, thereby preventing the Coanda effect from causing cold wind to blow on people.

[0009] The air guide device of the air conditioner mentioned above includes the first air guide rib, which is arranged at the front air outlet of the convex air guide surface. This arrangement makes the cooling effect on both sides of the air guide plate the same as that on other places.

[0010] The air guide device of the air conditioner described above further comprises second and third air guide ribs, each disposed at the air outlet on either side of the convex air guide surface. These air guide ribs enable air to be delivered further, directing airflow in the desired direction and preventing the Coanda effect from causing cold air to blow on people.

[0011] In the aforementioned air guide device for the air conditioner, the first air guide rib is connected at both ends to the second and third air guide ribs, forming an integrated structure. This arrangement provides a continuous air guide rib, which can deliver air farther, guide airflow in the desired direction, and prevent the Coanda effect from causing cold air to blow on people.

[0012] The air guide device of the air conditioner described above comprises an inner air guide plate, an outer air guide plate, a lug, and a beak. The inner air guide plate is connected to the outer air guide plate, and the lug and beak are provided on the inner air guide plate. The lug and beak are located at both ends of the air guide ribs and are connected to the drive assembly. This arrangement allows the drive assembly to smoothly drive the air guide assembly, resulting in an effective air flow diversion effect of the air guide plate during cooling or heating. The air guide ribs can achieve a longer air flow, guiding airflow in the desired direction for a comfortable user experience.

[0013] The air guide device of the air conditioner mentioned above, the driving assembly includes a first driving assembly and a second driving assembly,

[0014] The first drive assembly includes a push-out motor and a first drive connecting rod, the first drive connecting rod is connected to the hawk's beak, and the push-out motor drives the first drive connecting rod to push out;

[0015] The second drive assembly includes a second swing motor, a second drive link, and a rotary motor. The rotary motor is located within the second drive link and connected to the lug. The second swing motor drives the second drive link out, while the rotary motor drives the lug to rotate. This configuration is the preferred drive assembly, enabling faster and more stable driving of the air guide assembly. This ensures that the air guide plate provides excellent airflow guidance during cooling or heating, and the air guide ribs deliver air farther, guiding airflow in the desired direction for a more comfortable experience.

[0016] In the aforementioned air conditioner's air guide assembly, during cooling mode, the distance between the lower edge of the air outlet and the air guide assembly's rotation center is 59mm-61mm. The air guide assembly rotates clockwise around the rotation center to an angle of 5°-7° with the horizontal. This allows cool air to flow slowly from above to below, creating a cooling sensation as it passes over the body. The air guide assembly is tilted at a certain angle, ensuring that cool air reaches both the interior and exterior, preventing condensation and fundamentally resolving user complaints caused by condensation dripping.

[0017] In the aforementioned air conditioner's air guide assembly, when operating in heating mode, the distance between the lower edge of the air outlet and the rotation center of the air guide assembly is 84mm-86mm, and the air guide assembly rotates counterclockwise about the rotation center to an angle of 112°-114° with respect to the horizontal. This arrangement avoids the Coanda effect, ensures effective airflow, and enhances comfort.

[0018] An air conditioner is provided with the air guide device of the air conditioner.

[0019] The present invention has the following beneficial effects: The present invention comprises an air guide plate and air guide ribs. The air guide ribs are provided on the air guide surface of the air guide plate and located at the air outlet of the air guide surface. The included angle α between the height direction of the air guide ribs and the air guide surface is 90°<α<180°, and the height of the air guide ribs is 1-2 mm. The airflow passes through the specially structured air guide ribs, achieving a longer air delivery distance and guiding the airflow in the desired direction, providing a comfortable feeling.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] like Figure 1 As shown, an air guide device for an air conditioner includes an air guide component 1 and a drive component. The drive component is arranged in the air conditioner, and the air guide component 1 is located at the air outlet 16 of the air conditioner. Figure 1 As shown, the air guide assembly 1 is not only an air guide device of the air conditioner, but also a part of the appearance of the air conditioner. Therefore, the air guide assembly 1 is very important to the air conditioner.

[0042] like Figure 2 As shown, the wind guide assembly 1 includes a wind guide plate and wind guide ribs 21. The wind guide ribs 21 are arranged on the wind guide surface of the wind guide plate and located at the wind outlet at the upper end of the wind guide surface. Preferably, the wind guide plate is provided with an outwardly convex wind guide surface, or the wind guide plate is an outwardly convex wind guide plate, and the wind guide ribs 21 are arranged at the wind outlet at the upper end of the outwardly convex wind guide surface.

[0043] Specifically, the wind guide ribs 21 include first wind guide ribs 211, which are arranged at the front air outlet of the convex wind guide surface and along the length direction of the wind guide plate. This arrangement makes the cooling effect on both sides of the wind guide plate the same as other places.

[0044] Preferably, the wind guide ribs 21 also include a second wind guide rib 212 and a third wind guide rib 213. The second wind guide rib 212 and the third wind guide rib 213 are respectively arranged at the air outlets on both sides of the convex wind guide surface, that is, the second wind guide rib 212 is arranged at the air outlet on the left side of the convex wind guide surface, and the third wind guide rib 213 is arranged at the air outlet on the right side of the convex wind guide surface. This arrangement enables the wind guide ribs 21 to deliver air farther, guide the airflow to flow in the required direction, and avoid the Coanda effect causing cold wind to blow on people.

[0045] Further preferably, the ends of the first air guide rib 211 are respectively connected to the second air guide rib 212 and the third air guide rib 213 to form an integrated structure. Specifically, the left end of the first air guide rib 211 is connected to the second air guide rib 212, and the right end of the first air guide rib 211 is connected to the third air guide rib 213, forming an integrated structure. The first air guide rib 211, the second air guide rib 212, and the third air guide rib 213 form an airflow passage area 214. These continuous air guide ribs 21 allow for air to be delivered further, guiding airflow in the desired direction and avoiding the Coanda effect that can cause cold air to blow on people.

[0046] Preferably, the wind deflector includes an inner wind deflector 2, an outer wind deflector 3, a beak 4 and a lug 5. Preferably, the inner wind deflector 2 is provided with an outer convex wind deflector surface 201, or the inner wind deflector 2 is an outer convex wind deflector, the first wind guide rib 211 is provided at the front air outlet of the outer convex wind deflector surface 201 of the inner wind deflector 2, the second wind guide rib 212 and the third wind guide rib 213 are respectively provided at the air outlets on both sides of the outer convex wind deflector surface 201 of the inner wind deflector 2 (i.e., the left air outlet and the right air outlet), the inner wind deflector 2 is connected to the outer wind deflector 3, the beak 4 and the lug 5 are provided on the inner wind deflector 2, the beak 4 and the lug 5 are respectively located at the two ends of the inner wind deflector 2, that is, the two ends of the wind guide rib 21 (i.e., the wind guide rib 21 is arranged in the middle section), and the beak 4 and the lug 5 are connected to the drive assembly. This arrangement enables the drive assembly to be pushed out and rotated.

[0047] During cooling, cold air flows out from the air outlet and is guided by the special linear inner air guide plate 2. The airflow is blocked when passing through the air guide ribs 21, forcing the airflow to flow upward, which can make the airflow flow farther and prevent it from flowing downward along the wall. Finally, the cold air will slowly flow from the top to the bottom, achieving a shower-like air supply and preventing the airflow from blowing directly at the user, quickly lowering the room temperature while improving comfort. Alternatively, the drive component pushes out and rotates the air guide component. During heating, hot air flows out from the air outlet and is guided by the special linear inner air guide plate 2. The air guide ribs 21 guide the airflow to fall quickly and then slowly rise. When passing through the human body, there will be a comfortable feeling, thus forming a carpet-like heating system, quickly raising the room temperature and improving comfort. At the same time, the resistance loss during the diversion process is small, which improves the utilization rate of the air volume of the air conditioner and is relatively low in cost.

[0048] like Figure 3 As shown, the inner and outer air guide plates 2 and 3 are assembled and fixed by adhesive tape 9. Since the middle of the inner and outer air guide plates 2 and 3 form a cavity, a thermal insulation sponge 10 is attached to the inside of the air guide assembly 1, preferably to the cavity formed between the inner and outer air guide plates 2 and 3 of the air guide assembly 1. Since condensation is easily generated due to uneven heating and cooling inside and outside the double-layer air guide plate during cooling, the provision of the thermal insulation sponge 10 can prevent this from occurring.

[0049] According to Bernoulli's formula:

[0050] The pressure of the cold air flow in the atmosphere is almost unchanged, that is, P1=P2. When the cold air flow climbs over the air guide ribs, it is subject to friction resistance and loses a certain amount of energy, which reduces the flow rate after crossing the air guide ribs.

[0051] At the same time, the friction resistance f:

[0052]

[0053] C d is the friction coefficient, ρ is the cold air flow density, ν is the cold air flow velocity, l is the height of the air guide rib, L is the total length of the air guide rib, f is proportional to l; at the same time, the smaller α is, the greater the resistance is.

[0054] According to the above formula, the present invention has specific requirements for the air guide ribs 21 on the air guide surface of the inner air guide plate 2. The setting angle and height of the air guide ribs 21 have a significant impact on the flow direction of the cold air flow. Regarding the height of the air guide ribs 21, if the height of the air guide ribs 21 is too small, it is difficult to lift the cold air flow, and the cold air flow still flows downward along the air guide surface, posing a hidden danger of cold wind blowing people; if the height of the air guide ribs 21 is too large, the cold air flow loss is too large, and the room cooling efficiency is low.

[0055] Therefore, the height of the air guide ribs 21 is set to 1-2 mm. When the rib height is 1-2 mm, cold air can be prevented from reaching people at a height of 1.8 m, while the original height of 1.5 m prevents cold air from reaching people. At the same time, the room's cooling efficiency is improved. Furthermore, the vertical surfaces of the air guide ribs 21 and the air guide surface must not be rounded to prevent the Coanda effect, which can cause cold air to reach people.

[0056] Generally, the length of this rib should be greater than or equal to the length of the air conditioner's air outlet. That is, the air coming out of the air outlet must pass through the air guide rib, thereby changing its flow direction and raising the height of the cold air. As can be seen from the formula, as the length of the air guide rib increases, the friction resistance of the airflow increases. However, because the height of the air guide rib is small (1mm-2mm), the overall friction resistance is also very small. Therefore, extending the air guide rib to a length greater than the air outlet has little effect on the flow rate. The present invention can customize the length and position of the air guide rib 21 to meet the needs of different consumers. The rib can be beautified while ensuring that performance requirements are met, and it does not necessarily have to be a simple square rectangular bar. The presence of air guide ribs 21 on the left, middle, and right sides of the air outlet can ensure that cold air does not blow on people at different positions. However, due to the air supply angle on the left and right sides, it is difficult for the cold air flow to reach directly, resulting in slower cooling in the above areas. If the air guide ribs 21 are only arranged in the middle section and the air guide ribs 21 are eliminated on both sides, it can ensure uniform heating and cooling in each area.

[0057] like Figure 4 、 5 As shown, in this embodiment, the included angle between the air guide surface and the air guide ribs in the height direction is α. When 0°<α<90°, the cold airflow tends to flow back to the air outlet, resulting in low cooling efficiency. When α=90°, the Coanda effect of the cold airflow is prevented, and it no longer flows downward along the air guide surface. However, the cold airflow encounters the greatest resistance, which can easily lead to air loss. When 90°<α<180°, the cold airflow flows upward with less resistance, achieving a balance between comfort and cooling efficiency.

[0058] The best implementation of the present invention is that the rib height is 1 mm and the angle α is selected within the range of 90°<α≤120°, which has a better effect. The best value can be selected based on preliminary experiments.

[0059] like Figure 6 、 7 As shown, in this embodiment, the driving assembly includes a first driving assembly 6 and a second driving assembly 7. The first driving assembly 6 includes a pushing motor 61 and a first driving connecting rod 62. The first driving connecting rod 62 is connected to the hawk's beak 4. The pushing motor 61 drives the first driving connecting rod 62 to push out.

[0060] The second drive assembly 7 includes a second swing motor 71, a second drive connecting rod 72, and a rotary motor. The rotary motor is located within the second drive connecting rod 72 and connected to the lug 5. The second swing motor 71 drives the second drive connecting rod 72 to be pushed out, while the rotary motor drives the lug 72 to be rotated. The push-out motor 61 and the second swing motor 62 operate synchronously to push the air guide assembly 1 out, while the rotary motor rotates the air guide assembly 1. This configuration is the preferred drive assembly, capable of driving the air guide assembly 1 to the cooling or heating position more quickly and stably.

[0061] The air conditioner is equipped with a first drive box 63 and a second drive box 73. The first drive box 63 is equipped with an ejection motor 61 for driving the first drive link 62, and the second drive box 73 is equipped with a second swing motor 71 for driving the second drive link 72. The left end of the air guide assembly 1 is fixed to the first drive link 62 via the hawk beak 4, and the right end of the air guide assembly 1 is fixed to the rotary motor inside the second drive link 72 via the lug 5. The ejection motor 61 drives the first drive link 62, and the second swing motor 71 drives the second drive link 72, thereby ejecting the air guide assembly 1. The rotary motors work synchronously to rotate the air guide assembly 1.

[0062] like Figure 8 As shown, when the air guide assembly 1 is closed, it blocks the air outlet 16 and forms a 27° angle with the horizontal plane. The inner air guide plate 2 is positioned inside, and the outer air guide plate 3 is positioned outside. The drive trajectory 17 represents the trajectory curve of the air guide assembly 1 driven by the first drive box 63 and the second drive box 73. Furthermore, the rotation center 8 represents the rotation center of the air guide assembly 1.

[0063] like Figure 9 、 11As shown, in cooling mode: the pushing motor 61 and the second swing motor 71 work, first pushing the air guide component 1 a certain distance: that is, the distance A1 between the lower edge of the air outlet 16 and the rotation center 8 of the air guide component 1 is 59mm-61mm, preferably 59mm, 60mm, 61mm, and the rotating motor works to drive the air guide component 1 around the rotation center 8, and rotates clockwise to 5°-7° with the horizontal direction, preferably 5°, 6°, 7°. At this time, cold wind blows from the inner air guide plate 2 near the air outlet 16 to the outer air guide plate 3, making it impossible for the air guide component 1 to be adhered to one side of the thermal insulation sponge 10 due to the adhesion of the fixing tape 9. Since cold wind blows from both the inside and the outside, condensation will not be formed due to uneven temperature. Most of the cold air flow flows upward along the air guide surface of the inner air guide plate 2. After a certain distance away from the air outlet 16, the cold air flow encounters the air guide rib 21, and the cold air flow is blocked and forced to climb to the other side of the first air guide rib 211. At this time, the cold air flow is raised to a certain height and continues to flow along the air guide surface of the first air guide rib 211, making the upward trend more obvious, so that the air flow flows farther, and is not allowed to flow downstream along the wall, thereby avoiding the occurrence of the Coanda effect; [Coanda effect: When the curvature of the large convex hull structure profile on the rear side of the inner air guide plate 2 is small, the air flow flows along the wall profile. This phenomenon is called the Coanda effect, commonly known as the wall attachment effect. During cooling, the cold air tends to flow downward, which can easily blow people. At the same time, because the cold air blown to the outer air guide plate 3 is not dispersed much, it has little impact on the overall air volume. Since the density of cold air is greater than that of air at room temperature, the cold air will slowly flow from top to bottom, achieving a shower-like air supply and preventing the air flow from blowing directly towards the user, quickly lowering the room temperature while improving comfort. Specific experimental data are shown in Table 1 and Curve Figure 12 and cold wind-sensitive areas Figure 14 .

[0064] Table 1: Refrigeration and air supply comfort test data

[0065]

[0066] like Figure 10 、 11As shown, in heating mode, the push motor 61 and the second swing motor 71 operate to first push the air guide assembly 1 a certain distance: the distance A2 between the lower edge of the air outlet 16 and the rotation center 8 of the air guide assembly 1 is 84mm-86mm, preferably 84mm, 85mm, or 86mm. The rotation motor then operates to drive the air guide assembly 1 to rotate counterclockwise around the rotation center 8 to an angle of 112°-114° with respect to the horizontal, preferably 112°, 113°, or 114°. The hot air follows the guide direction of the inner air guide plate 2, and the hot air flow flows downward along the air guide surface of the inner air guide plate 2. After a certain distance away from the air outlet 16, the hot air flow encounters the air guide rib 21, and the hot air flow is blocked and forced to climb to the other side of the first air guide rib 211, and continues to flow along the air guide surface of the first air guide rib 211, making the downward trend more obvious, avoiding the occurrence of the Coanda effect. Since the density of hot air is less than the density of air at room temperature, the hot air is guided by the air guide plate to fall quickly during heating, and then slowly rises. When passing through the human body, there will be a comfortable feeling, thereby forming a carpet-like heating, quickly raising the room temperature and improving comfort. Specific experimental data are shown in Table 2, Table 3, and Curve Figure 13 and wind-affected areas Figure 15 .

[0067] Table 2: Heating and air supply test data 1

[0068]

[0069] Table 3: Heating and air supply test data 2

[0070]

[0071] The dimensions A1, A2, rotation angle, etc. of the air guide assembly 1 can be adjusted within any appropriate range to achieve the above functions.

[0072] In this embodiment, the inner air deflector 2 is made of plastic, preferably LCPA-GF55, replacing steel with plastic. This increases the curvature of the inner air deflector 2's profile, enhancing the rigidity and strength of the air guide assembly 1. This replaces traditional aluminum profiles, significantly reducing processing and material costs. This LCPA-GF55 material eliminates the problem of the two materials being unable to form a compatible structure. It also ensures the rigidity and strength of the large, double-layered air deflector, thereby maintaining the aesthetics of the air conditioner.

[0073] The beneficial effects of the present invention are as follows: 1. During cooling, the double-layer large air guide plate is pushed out and placed at the lower edge of the air outlet 16. The double-layer large air guide plate guides the airflow through the special profile of the inner air guide plate 2. Since the density of cold air is greater than the density of air at normal temperature, during cooling, the cold air is guided by the inner air guide plate 2 to blow to high altitudes, and then slowly descends, achieving shower-like air supply without directly blowing the airflow toward the user, thereby quickly lowering the room temperature and improving comfort.

[0074] 2. During heating, the double-layer large air guide plate is pushed out and placed on the upper edge of the air outlet 16. The double-layer large air guide plate guides the airflow through the special profile of the inner air guide plate 2. Since the density of hot air is lower than that of air at room temperature, during heating, the hot air is guided by the inner air guide plate 2 to fall quickly to the ground and then slowly rise, thus forming a carpet-like heating, quickly raising the room temperature and improving comfort.

[0075] 3. During cooling, the air guide assembly 1 is tilted at a certain angle so that cold air can be blown both inside and outside, thereby preventing the formation of condensation.

[0076] 4. Abandoning traditional aluminum profiles, the inner air guide plate is made of LCPA-GF55 plastic instead of steel, significantly reducing processing and material costs. At the same time, because aluminum profiles cannot be processed into complex structures, the structure that cooperates with the drive structure is generally designed on a separate air guide plate. In this case, if the second air guide plate is made of a special appearance material such as acrylic (PMMA), which can only have a flat structure, the two materials cannot be processed into a compatible structure. This LCPA-GF55 material replaces aluminum profiles to solve this problem of the two materials being unable to be processed into a compatible structure, while also ensuring the rigidity and strength of the double-layered air guide plate, thereby maintaining the aesthetics of the air conditioner.

[0077] An air conditioner is provided with the air guide device of the air conditioner.

[0078] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
