Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air-conditioning equipment, and in particular to an air outlet panel structure and an air-conditioning unit. Background Art
[0002] Air conditioners are often used in environments with high humidity, which can cause condensation to form on the panel near the air conditioner outlet. Excessive condensation can accumulate, reducing the user experience and potentially affecting underlying electrical and electronic components, ultimately impacting the safety of the air conditioner.
[0003] Condensation occurs primarily due to two factors. First, higher ambient air temperatures lead to higher water vapor saturation and, therefore, higher humidity. Second, the air outlet temperature of the air conditioner is very low, exchanging energy with the panel, lowering its temperature. This is especially true when using materials with good thermal conductivity, such as sheet metal. When high-temperature air flows near the panel, it exchanges heat with the panel surface, cooling it down. This lowers the water vapor saturation, causing it to condense and adhere to the panel due to its viscosity, gradually accumulating to form condensation.
[0004] The user needs of air conditioners may vary in the usage environment, and with the gradual deepening of intelligent air conditioners, the electronic control equipment of air conditioners will gradually increase. Therefore, the prevention and treatment of condensation has become more important.
[0005] like Figure 1 As shown, the air-conditioning indoor unit 1 has an air outlet 2. In order to realize the air-guiding function, it generally has horizontal air-guiding blades and vertical air-guiding blades. A rectangular sheet metal frame is generally used around the blade structure to fix the blade structure, and then the rectangular sheet metal frame is fixed to the skeleton structure of the body. Figure 2 This is the flow field simulation result diagram at the air outlet of the air conditioner indoor unit. Under the room temperature of 30℃, the cold air flowing out of the air outlet causes negative pressure on both sides, causing the humid air in the air to flow with it. The panel is cooled by the cold air at the air outlet and the temperature is lower. The water vapor in the air condenses at the dotted position around the air outlet 2.
[0006] To prevent condensation, a common approach is to add insulation materials like sponge to the outlet housing, thereby blocking heat transfer and raising the surface temperature to reduce condensation. However, this approach structurally limits the air conditioner's assembly due to the sponge. Furthermore, the outlet structure is typically narrow, making it difficult to attach insulation materials, which increases assembly time and costs.
[0007] There is also a solution in the existing technology that improves local air guide blades to partially distribute the airflow at the air outlet to the left and right to prevent condensation on the sides of the air frame. However, this technical solution has limited effect on regulating the temperature of the air frames on the left and right sides of the air outlet. The hot air on both sides will still circulate around the panels on both sides, causing water vapor to condense on the panels. Summary of the Invention

[0009] An embodiment of the present application provides an air outlet panel structure, including a panel body and an air outlet opened on the panel body. The air outlet panel structure also includes a guide plate assembly, which is installed at the air outlet. The guide plate assembly is used to blow the airflow at the air outlet to the part of the panel body away from the air outlet.
[0010] In one embodiment, an anti-condensation air outlet is opened on the side of the air outlet on the panel body, and a guide plate assembly is installed on the anti-condensation air outlet.

[0013] In one embodiment, the guide plate assembly includes an inner guide plate and an outer guide plate installed on the anti-condensation air outlet. The inner guide plate is close to the air outlet on the anti-condensation air outlet, and the outer guide plate is far away from the air outlet on the anti-condensation air outlet. The inner guide plate and the outer guide plate cooperate to blow the airflow of the anti-condensation air outlet to the part of the air outlet away from the panel body.
[0014] In one embodiment, the inner guide plate and / or the outer guide plate can be movably arranged to change the size of the anti-condensation air outlet.
[0015] In one embodiment, a first concave guide portion is formed at the air outlet end of the guide inner plate, and the first concave guide portion is used to guide the airflow of the anti-condensation air outlet to a portion of the panel body away from the air outlet.
[0016] In one embodiment, a first convex guide portion is formed at the air outlet end of the guide outer plate, and the first convex guide portion and the first concave guide portion cooperate to guide the airflow of the anti-condensation air outlet.
[0017] In one embodiment, a first tapered air duct is formed between the first concave air guide portion and the first convex air guide portion, and the first tapered air duct tapers toward the air outlet end of the anti-condensation air outlet.

[0019] In one embodiment, a second convex guide portion protruding relative to the first concave guide portion is formed at the air inlet end of the guide inner plate, and the second convex guide portion constitutes a partial structure of the second tapered air duct.
[0020] In one embodiment, a second concave guide portion recessed relative to the first convex guide portion is formed at the air inlet end of the guide outer plate, the second concave guide portion cooperates with the second convex guide portion, and a second tapered air duct is formed between the second concave guide portion and the second convex guide portion.
[0021] In one embodiment, the second tapered air duct and the first tapered air duct form an S-shaped air duct.
[0022] In one embodiment, the anti-condensation air vent and the guide plate assembly are respectively arranged on the left and right sides of the air outlet.
[0023] The present application also provides an air-conditioning unit, including an air outlet panel structure, which is the above-mentioned air outlet panel structure.
[0024] In the above embodiment, the deflector assembly directs the airflow from the air outlet toward the portion of the panel body away from the outlet.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.
[0034] Figure 3 and Figure 4 This embodiment of the air outlet panel structure of the present invention includes a panel body 10 and an air outlet 11 formed on the panel body 10. Anti-condensation air outlets 12 are formed on the panel body 10 on the side of the air outlet 11. The air outlet panel structure also includes a deflector assembly mounted on the anti-condensation air outlet 12 to direct the airflow from the anti-condensation air outlet 12 toward a portion of the panel body 10 away from the air outlet 11.
[0035] Using the technical solution of the present invention, an anti-condensation vent 12 is provided on the panel body 10, located on the side of the air outlet 11. The airflow from the anti-condensation vent 12 is directed by a deflector assembly toward the portion of the panel body 10 away from the air outlet 11. This changes the air passing around the air outlet 11 on the panel body 10 from hot and humid indoor air to cool air from the unit, which has lower humidity and temperature. This effectively solves the problem of condensation on both sides of the air conditioner's air outlet. Furthermore, this technology can avoid or reduce the amount of sponge used in the panel body, improving assembly efficiency.
[0036] As an optional embodiment not shown in the figures, it is also possible to not provide the anti-condensation air vent 12, and only install the deflector assembly at the air outlet 11, so that the deflector assembly blows the airflow at the air outlet 11 to the portion of the panel body 10 away from the air outlet 11. It should be noted that the deflector assembly is installed at the air outlet 11, which means that it can be installed at the side of the air outlet 11 or at an opening on the side of the air outlet 11.
[0037] As a more preferred embodiment, Figure 3 As shown, the anti-condensation vents 12 and the guide plate assembly are respectively arranged on the left and right sides of the air outlet 11, thereby effectively solving the condensation problem on the left and right sides of the air outlet 11. As another optional embodiment, the anti-condensation vents 12 and the guide plate assembly can also be respectively arranged on the upper and lower sides of the air outlet 11.
[0038] like Figure 3 and Figure 4 As shown, in the technical solution of the present invention, the deflector assembly is installed on the anti-condensation air outlet 12. The deflector assembly has an open state that opens the anti-condensation air outlet 12 and a closed state that closes the anti-condensation air outlet 12. This allows the deflector assembly to be operated in the open state when the air humidity is too high; when there is no condensation problem, such as when the system is not in operation, the air is relatively dry, or when the system is in heating mode, the deflector assembly is operated in the open and closed state, closing the anti-condensation air outlet 12 to save air volume and ensure the structural plane of the outlet is flush.
[0039] As a more preferred embodiment, the deflector assembly also includes an air adjustment state for adjusting the opening size of the anti-condensation air outlet 12. In this way, the air volume can be changed by reasonably adjusting the opening size of the anti-condensation air outlet 12 according to the air humidity.
[0040] like Figure 3 and Figure 5 As shown, the deflector assembly includes an inner deflector plate 20 and an outer deflector plate 30 mounted on the anti-condensation air outlet 12. The inner deflector plate 20 is located on the anti-condensation air outlet 12 near the air outlet 11, while the outer deflector plate 30 is located on the anti-condensation air outlet 12 away from the air outlet 11. The inner deflector plate 20 and the outer deflector plate 30 cooperate to direct the airflow from the anti-condensation air outlet 12 toward the portion of the panel body 10 away from the air outlet 11. In actual use, the cooperation between the inner deflector plate 20 and the outer deflector plate 30 better directs the airflow from the anti-condensation air outlet 12 toward the portion of the panel body 10 away from the air outlet 11. Optionally, the inner deflector plate 20 and the outer deflector plate 30 are formed by inner and outer deflector plates made of sheet metal or plastic.
[0041] like Figure 3 and Figure 4As shown, in the technical solution of this embodiment, the inner guide plate 20 is movably arranged relative to the outer guide plate 30 to change the size of the anti-condensation air outlet 12. Preferably, the inner guide plate 20 can be provided with a guide rail, a solenoid valve, or other mechanical components to make its structure a movable component, and the relative position can be changed by moving a single component or a pair of components. As another optional embodiment, the outer guide plate 30 can also be movably arranged relative to the inner guide plate 20, or both the inner guide plate 20 and the outer guide plate 30 can be movably arranged.
[0042] like Figure 5 and Figure 6 As shown, the outlet end of the guide inner plate 20 is formed with a first concave guide portion 21. When in use, the first concave guide portion 21 can guide the airflow of the anti-condensation air outlet 12 to the part of the panel body 10 away from the air outlet 11. Figure 6 As shown, preferably, in the technical solution of this embodiment, the first concave guide portion 21 is composed of arc surfaces R41 and R42.
[0043] As a more preferred embodiment, the air outlet end of the guide outer plate 30 is formed with a first convex guide portion 31, and the first convex guide portion 31 cooperates with the first concave guide portion 21 to guide the airflow of the anti-condensation air outlet 12, thereby achieving a better guiding effect on the airflow of the anti-condensation air outlet 12. Figure 6 As shown, preferably, in the technical solution of this embodiment, the first convex guide portion 31 is composed of arc surfaces R51, R52 and R53.
[0044] As a more preferred embodiment, Figure 6 As shown, a first tapered air duct is formed between the first concave guide portion 21 and the first convex guide portion 31, and the first tapered air duct gradually shrinks toward the air outlet end of the anti-condensation air outlet 12, thereby increasing the wind pressure and improving the blowing effect of the air passing around the air outlet 11 on the panel body 10.
[0045] More preferably, in the technical solution of this embodiment, a second tapered air duct connected to the first tapered air duct is formed between the guide inner plate 20 and the guide outer plate 30 and located upstream of the first tapered air duct. The second tapered air duct tapers toward the direction of the first tapered air duct, and the purpose of the second tapered air duct is also to increase the wind pressure. More preferably, as Figure 6As shown, in the technical solution of this embodiment, the air inlet end of the inner guide plate 20 is formed with a second convex guide portion 22 that protrudes relative to the first concave guide portion 21. The second convex guide portion 22 constitutes part of the structure of the second tapered air duct. The provision of the second convex guide portion 22 helps the airflow discharged from the air outlet end of the outer guide plate 30 to form flow characteristics that are more closely aligned with the panel body 10, thereby further improving the purge effect on the air passing around the air outlet 11 on the panel body 10. Optionally, the second convex guide portion 22 is composed of curved surfaces R42, R43, and R44.
[0046] like Figure 6 As shown, in the technical solution of this embodiment, a second concave guide portion 32 is formed at the air inlet end of the outer guide plate 30, which is recessed relative to the first convex guide portion 31. The second concave guide portion 32 cooperates with the second convex guide portion 22 to enhance the flow channel's drainage effect. Optionally, the second concave guide portion 32 is formed by a curved surface R54. The aforementioned second tapered air duct is formed between the second convex guide portion 22 and the second concave guide portion 32.
[0047] It should be noted that the above-mentioned concave-convex structure is relative to the plane where the inner side wall of the anti-condensation air outlet 12 is located.
[0048] As a more preferred embodiment, the second tapered air duct and the first tapered air duct form an S-shaped air duct.
[0049] The present invention also provides a specific embodiment, wherein the above R41, R42, R43, and R44 are respectively centered on P41, P42, P43, and P44. The above R51, R52, R53, and R54 are respectively centered on P51, P52, P53, and P54. Figure 6 As shown in the figure, assuming the total width of the structure on one side of the outlet is D, the boundary line of the inner guide plate 20 and the outer guide plate 30 is drawn with the center P41 as the coordinate origin (0,0). It should be noted that this boundary line is the internal boundary of the inner guide plate 20 and the outer guide plate 30. This boundary line is used as the basis for structural processing of the inner guide plate 20 and the outer guide plate 30 on both sides of the outlet.
[0050] Preferably, the radius of the arc segment R41 of the guide inner plate 20 is D / 5, and the angle is 90°.
[0051] Preferably, the coordinates of the center P42 of the arc segment R42 are (D / 5, 0), the radius of R42 is 2D / 5, and the angle is 45°.
[0052] Preferably, the intersection of the extended line of the connecting line of the center P41 and the center P42 and the left boundary is used as the center P43, and a 90° arc is continued from the end of the arc R42.
[0053] Preferably, the coordinates of the circle center P44 are (D / 5, -4D / 5), which is a 45° arc with a radius of 2D / 5 starting from the end of the circle center P43.
[0054] Preferably, the coordinates of the center P51 of the arc R51 of the guide outer plate 30 are (0, D / 15), the radius of R51 is D / 15, and the arc is 90°.
[0055] Preferably, the radius of the arc R52 is 2D / 15, the coordinates of the center of the arc are (2.414D / 15, 2.414D / 15), and the arc is 45°.
[0056] Preferably, the coordinates of the center P53 of the arc R53 are (3D / 15, 3D / 15), the radius is 4D / 15, and the arc is 45°.
[0057] Preferably, the coordinates of the center P54 of the arc R54 are (2.414D / 15, -11.17D / 15), and the arc is 90°.
[0058] Preferably, the inner guide plate 20 can be mounted on the outer edge of the frame at the boundary of the air outlet or can be integrated with the frame. The outer guide plate 30 can be fixed or integrated with the panels on the left and right sides of the body. Its three-dimensional structure is as follows: Figure 5 shown.
[0059] As another optional embodiment, the inner guide plate 20 and outer guide plate 30 can be divided into multiple sections, with partially enclosed spaces between them. The sheet metal profile can be modified to change the arc radius and center position, or replaced with a straight plate or other shaped flow channel to divert the flow, changing the flow direction on both sides.
[0060] The present invention also provides an air-conditioning unit, which includes the above-mentioned air outlet panel structure. The use of the above-mentioned air outlet panel structure can effectively solve the problem of condensation water easily generated on the air-conditioning unit.
[0061] From the above content, it can be seen that the present invention changes the air flow structure at the air conditioner outlet, thereby effectively utilizing the closed space on both sides of the air outlet as a flow channel, and changes the air flow on both sides of the air outlet through the structure of the second gradually contracting air channel and the first gradually contracting air channel. Through simulation verification, as shown in FIG Figure 7 As shown, the results show that under the application conditions of the present invention, the flow field of the traditional air outlet structure is more conducive to preventing condensation on the panels on both sides of the air-conditioning outlet.
[0062] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
