Description

Technical Field

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

[0002] With the development of the times and the progress of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners. In order to improve the efficiency of air supply, a single air guide plate structure is now mostly used for air supply.

[0003] For example, Chinese patent "CN113310116B" discloses "a wall-mounted air conditioner indoor unit and its air guide plate." This air guide plate changes the flow direction of the airflow through the air-lifting section, causing the airflow to gradually move away from the air guide plate body and flow upward at an angle, i.e., blowing upward, making the airflow direction closer to vertical upward. This fully meets the requirements of the upward angle when the air conditioner is cooling or in a non-blowing mode. At the same time, multiple guide ribs guide the airflow to gradually deflect towards both ends of the length of the air guide plate body, increasing the diffusion angle of the air outlet in the left and right directions, and achieving wide-angle air supply. However, due to its installation structure, the air guide plate can only be adjusted to a certain angle and cannot achieve an all-round air supply effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air guide structure, an indoor air conditioning unit, and an air conditioner, which solves the problem that the air guide plate in the existing technology can only be adjusted to a certain angle and cannot achieve an all-round air supply effect.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] An air guiding structure, comprising:

[0007] The first air guide plate is curved and located at the windward end;

[0008] The second air guide plate is arc-shaped and located at the leeward end; the first air guide plate is fastened to the second air guide plate to form a cavity; and

[0009] A rotating shaft is connected to the first air guide plate so that the cavity rotates around the rotating shaft as the axis.

[0010] Preferably, the end of the second air guide plate extends outward along its tangential direction to form an extension, and the extension has a through hole.

[0011] Preferably, there are multiple through holes, which are distributed at intervals along the length and width directions of the extension.

[0012] Preferably, the angle between the through hole and the tangent direction is α, where α satisfies 30°≤α≤45°.

[0013] Preferably, the cavity is provided with a heat insulation layer.

[0014] Preferably, the insulation layer is made of foam or sponge.

[0015] Preferably, the cross-section of the first air guide plate is "S" shaped so that the cavity has a large end and a small end, and the rotating shaft is set close to the large end.

[0016] According to embodiments of this utility model, the following technical solutions are also adopted:

[0017] An indoor air conditioning unit includes a front frame assembly, a base, and an air guide structure, wherein an air outlet is formed between the front frame assembly and the base, and a rotating shaft is rotatably positioned at the air outlet.

[0018] Preferably, the front frame assembly is recessed inward on the side near the air outlet to form an arc-shaped groove.

[0019] An air conditioner, including an indoor unit.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this design, the first and second air guide plates are fastened together to form an air guide structure with a cavity. With the help of the rotating shaft, the air guide structure can rotate at the air outlet of the air conditioner, thereby dividing the air outlet of the air conditioner into air supply channels in different directions. Furthermore, through the Coanda effect of the arc surface structure of the first and second air guide plates, air supply at multiple angles can be achieved, reducing the areas that cannot be reached by the air supply and avoiding blind spots in air supply.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] This utility model embodiment proposes an air guiding structure, including:

[0031] The first air guide plate 1 is arranged in an arc shape and located at the windward end;

[0032] The second air guide plate 2 is arc-shaped and located at the leeward end; the first air guide plate 1 is fastened to the second air guide plate 2 to form a cavity 3; and

[0033] The rotating shaft 7 is connected to the first air guide plate 1 so that the cavity 3 rotates around the rotating shaft 7 as the axis.

[0034] In the embodiments of this utility model, the first air guide plate 1 and the second air guide plate 2 are interlocked to form an air guiding structure, such as... Figure 1 As shown, when the air guide structure is not in operation, it is closed at the air outlet, with the first air guide plate 1 located at the windward end and the second air guide plate 2 located at the leeward end. When guiding the airflow, the first air guide plate 1 and the second air guide plate 2 will move relative to each other at the air outlet. To ensure the stability of the movement, a rotating shaft 7 is used as the positioning basis for the first air guide plate 1 and the second air guide plate 2. The first air guide plate 1 and the second air guide plate 2 rotate around the axis of the rotating shaft 7 by rotating the rotating shaft 7. The rotating shaft 7 can be driven by an electric motor or electric motor, which is quiet and efficient. The two ends of the rotating shaft 7 are respectively connected to the two ends of the first air guide plate 1 for easy installation.

[0035] like Figure 2 As shown, both the first air guide plate 1 and the second air guide plate 2 are arc-shaped, and the arc lengths between the first air guide plate 1 and the second air guide plate 2 are different. The outer surface of the first air guide plate 1 is a convex arc layer, and the outer surface of the second air guide plate 2 is a concave arc layer. The arc length of the convex arc layer is greater than that of the concave arc layer. Combined with the Coanda effect of the convex and concave arc layers, i.e., the effective wall-adhesion effect, the air guiding is optimized, fully meeting the all-round air supply of the single pendulum, making the air supply angle more accurate and wider. At the same time, the cavity 3 reduces the overall mass and reduces the torque requirement of the rotating shaft 7.

[0036] In omnidirectional air supply, based on the clockwise and counterclockwise rotation angles of the first air guide plate 1 and the second air guide plate 2 driven by the rotating shaft 7, such as... Figure 3As shown, based on the initial state, i.e. Figure 1 As shown, the first air guide plate 1 and the second air guide plate 2 are rotated clockwise by the rotating shaft 7 until they are in a horizontal state. Most of the airflow is guided by the outward convex arc layer to achieve horizontal air delivery. Figure 4 As shown, in the Figure 1 Rotate counterclockwise on the basis or with Figure 3 While continuing to rotate clockwise, the rotating shaft 7 drives the first air guide plate 1 and the second air guide plate 2 to the upper position of the air outlet. The concave arc layer guides the airflow, achieving vertical air delivery. Unlike horizontal and vertical air delivery, when the rotating shaft 7 is electrically driven, the angle between the air guide structure and the bottom of the air outlet can be adjusted to 45° by controlling the rotation amplitude of the rotating shaft 7, achieving bottom 45° air delivery. Similarly, controlling the angle between the air guide structure and the top of the air outlet to adjust to 45° achieves top 45° air delivery. See [link to relevant documentation]. Figure 5 and Figure 6 As shown.

[0037] Specifically, the end of the second air guide plate 2 extends outward along its tangential direction to form an extension 4, and the extension 4 has a through hole 5; for example Figure 2 As shown, the extension 4 extends away from the first air guide plate 1 to form the tail area of ​​the second air guide plate 2. Under the action of the through hole 5, it can uniformly guide the upper airflow during horizontal air supply, reduce the temperature fluctuation of the lower airflow, and reduce the generation of condensate in the lower part.

[0038] Meanwhile, there are multiple through holes 5, which are distributed at intervals along the length and width directions of the extension 4. Under the premise of guiding the flow, the overall mass can be further reduced. Furthermore, the angle between the through hole 5 and the tangent direction is α, which satisfies 30°≤α≤45°. When processing the through hole 5, the angle between the through hole 5 and the tangent direction is selected between 30° and 45°, preferably 40°, which effectively provides horizontal air supply while guiding the upper airflow.

[0039] Specifically, such as Figure 2 As shown, the cavity 3 is provided with a heat insulation layer 6; under the action of the heat insulation layer 6 in the cavity 3, the first air guide plate 1 and the second air guide plate 2 can be prevented from overheating or overcooling, thereby reducing the temperature difference between the air guide structure and the airflow and effectively reducing the generation of condensate.

[0040] Preferably, the insulation layer 6 is made of foam or sponge to further ensure the insulation efficiency of the first air guide plate 1 and the second air guide plate 2.

[0041] like Figure 2As shown, the cross-section of the first air guide plate 1 is "S" shaped, so that the cavity 3 has a large end 61 and a small end 62. The rotating shaft 7 is set close to the large end 61. Under the premise of achieving the Coanda effect, by improving the cross-sectional size of the cavity 3, the cross-sectional size of the cavity 3 gradually decreases towards the extension 4, making the air guide structure gradually change from thick to thin at one end. At the same time, the thick end cooperates with the insulation layer 6 to ensure that no condensation is generated, improving the feasibility of the air supply mode. Meanwhile, by setting the rotating shaft 7 close to the large end 61, the position of the rotating shaft 7 is close to the center of mass region, further reducing the rotational torque requirement of the air guide structure.

[0042] This utility model embodiment also proposes an indoor air conditioning unit, including a front frame assembly 8, a base 9, and an air guide structure. An air outlet 10 is formed between the front frame assembly 8 and the base 9, and a rotating shaft 7 is rotatably disposed at the air outlet 10. The side of the front frame assembly 8 near the air outlet 10 is recessed inward to form an arc-shaped groove 11. Under the action of the arc-shaped groove 11, when the air guide structure delivers air vertically and at a bottom angle, the arc-shaped surface of the air guide structure can fit into the arc-shaped groove 11, allowing the convex arc layer of the air guide structure to better guide the airflow.

[0043] This utility model embodiment also proposes an air conditioner, including an indoor unit. The specific structure of the indoor unit is as described in the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
