Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and more specifically, to an air outlet guide structure adapted to a fan and an air conditioner. Background Technology
[0002] Kitchen air conditioners are temperature control devices specifically designed for kitchens, and typically include a compressor, condenser, evaporator, and fan. In existing kitchen air conditioner technology, ambient indoor air is cooled by heat exchange in the evaporator and then blown into the kitchen by the fan.
[0003] However, the air outlet of the existing fan is directly set on the air conditioning unit, which results in obvious airflow separation at the outlet. This causes a lot of noise from the air outlet, which seriously affects the comfort of the users and the user experience of the product. Utility Model Content
[0004] The purpose of this invention includes, for example, providing an air outlet guide structure and an air conditioner adapted to a fan, which can improve the problems of uneven air outlet and airflow separation in the prior art.
[0005] The embodiments of this utility model can be implemented as follows:
[0006] In a first aspect, this utility model provides an air outlet guiding structure adapted to a fan, including a guide tube that is consistent with or approximately consistent with the deformation direction of the fan outlet. The guide tube includes: at least one first guide plate that is consistent with or approximately consistent with the tangential extension direction of the fan outlet, and a side plate adapted to the first guide plate to form the guide tube. The first guide plate and the side plate enclose a cylindrical guiding space.
[0007] In an optional embodiment, from the inlet to the outlet of the guide tube, the first guide plate includes an arc segment and a straight segment connected in sequence.
[0008] The tangent direction of the arc segment is consistent with or approximately consistent with the tangent direction of the air outlet of the fan.
[0009] In an optional embodiment, the side plate includes a second guide plate disposed opposite to the first guide plate, and the first guide plate and the second guide plate are arranged in parallel.
[0010] The second guide vane has the same shape as the first guide vane.
[0011] In an optional embodiment, the arc segments of the first guide plate and the second guide plate have the same curvature.
[0012] In an optional embodiment, the straight segments of the first guide vane and the second guide vane remain parallel to each other.
[0013] In an optional embodiment, the side plate includes two opposing vertical plates that are parallel to each other, and the first guide plate, the second guide plate, and the two vertical plates enclose each other to form the guide tube.
[0014] In an optional embodiment, the upright plate is kept perpendicular to the first guide plate.
[0015] In an optional embodiment, a first connecting plate is further included, which is disposed at the inlet of the guide tube and can be connected to the air outlet of the fan.
[0016] In an optional embodiment, a second connecting plate is further included, which is disposed at the outlet of the guide tube; the second connecting plate can be connected to the air conditioning unit.
[0017] In an optional embodiment, the second connecting plate is perpendicular to the outlet of the guide tube.
[0018] Secondly, this utility model provides an air conditioner, which includes an air outlet guide structure adapted to the fan as described in any of the foregoing embodiments.
[0019] The beneficial effects of this utility model embodiment include, for example:
[0020] The airflow guiding structure adapted to the fan in this solution includes a guide tube, which has the same or approximately the same deformation direction as the fan outlet. This guides the air delivered from the fan outlet to flow smoothly along the extension direction of the guide tube. Furthermore, the first guide plate of the guide tube has the same or approximately the same tangential extension direction as the fan outlet. This ensures that after the low-temperature air in the fan is thrown out from the impeller, the airflow direction is exactly along the extension direction of the first guide plate, effectively aligning the first guide plate with the fan's airflow outlet direction and reducing flow resistance. Simultaneously, the air entering the kitchen becomes significantly more uniform, and reduced separation means lower noise levels. In summary, this fan-adapted airflow guiding structure is simple in structure, easy to install, and significantly improves the problems of uneven airflow and airflow separation in existing technologies, while also enhancing user comfort and product experience.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0033] from Figure 1 As can be seen, in the existing air conditioner, the air outlet of the fan structure 11 is directly installed on the air conditioner housing 12. When the air conditioner is running, the room temperature air becomes low-temperature air after heat exchange in the evaporator, and the low-temperature air is blown into the kitchen by the blower fan 21. Because the air outlet is directly connected to the air conditioner housing 12, the airflow separation at the air conditioner outlet is very obvious, which results in a large amount of noise from the air outlet, seriously affecting the comfort of the users and the user experience.
[0034] To improve the above-mentioned technical problems, the following embodiments provide an air outlet guide structure and an air conditioner adapted to a fan.
[0035] Please refer to Figure 2 This embodiment provides an air outlet guiding structure adapted to a fan, including a guide tube 300 that is consistent with or approximately consistent with the deformation direction of the air outlet of the fan 21. The guide tube 300 includes: at least one first guide plate 310 that is consistent with or approximately consistent with the tangential extension direction of the air outlet of the fan 21, and a side plate 320 adapted to the first guide plate 310 to form the guide tube 300. The first guide plate 310 and the side plate 320 enclose a cylindrical guiding space 301.
[0036] In this embodiment, the airflow guide tube 300 of the fan-adapted airflow guide structure is aligned with or approximately aligned with the deformation direction of the fan 21's air outlet. This guides the air delivered from the fan 21's air outlet to flow smoothly along the extension direction of the guide tube 300. Furthermore, the first guide plate 310 of the guide tube 300 is aligned with or approximately aligned with the tangential extension direction of the fan 21's air outlet. This ensures that after the low-temperature air in the fan 21 is ejected from the impeller, the airflow direction is precisely along the extension direction of the first guide plate 310, effectively aligning the first guide plate 310 with the airflow outlet direction of the fan 21, reducing flow resistance. Simultaneously, the airflow entering the kitchen becomes significantly more uniform, and reduced separation means lower noise levels. This significantly improves the problems of uneven airflow and airflow separation in the prior art, while also enhancing user comfort and product experience.
[0037] Please continue reading. Figure 2 , Figure 3 and Figure 4 As can also be seen from the figure, in the optional embodiment, from the inlet of the guide tube 300 to the outlet of the guide tube 300, the first guide plate 310 includes an arc segment 311 and a straight segment 312 connected in sequence; the tangent direction of the arc segment 311 is consistent with or approximately consistent with the tangent direction of the air outlet of the fan 21.
[0038] This configuration ensures a smooth transition between the first guide plate 310 and the air outlet of the fan 21, while the straight section 312 ensures a direct and convenient connection between the arc section 311 and the air conditioning unit 22.
[0039] It should be noted that the optional implementation method in which the tangent direction of the arc segment 311 is consistent with or approximately consistent with the tangent direction of the air outlet of the fan 21 can be: the tangent direction of the end of the first guide plate 310 can be parallel, coincident, approximately parallel or bend in the same direction as the tangent direction of the air outlet of the fan 21, etc., without any specific limitation.
[0040] In this embodiment, the tangential direction at the end of the first guide plate 310 coincides with the tangential direction at the air outlet of the fan 21.
[0041] Furthermore, the inner wall at the starting point of the arc segment 311 smoothly transitions with the inner wall of the air outlet of the fan 21, and the inner wall at the outlet of the arc segment 311 smoothly transitions with the inner wall of the straight segment 312. This reduces the wind resistance of the guide tube 300 to the air outlet of the fan 21, and also reduces the frictional loss between the air outlet of the fan 21 and the inner wall of the guide tube 300.
[0042] As can also be seen from the figure, in an optional embodiment, the side plate 320 includes a second guide plate 321 disposed opposite to the first guide plate 310, with the first guide plate 310 and the second guide plate 321 arranged in parallel; the second guide plate 321 has the same shape as the first guide plate 310. This arrangement ensures that air can smoothly transition between the first guide plate 310 and the second guide plate 321, avoiding turbulence caused by the angle between the two guide plates.
[0043] Specifically, in this embodiment, the second guide plate 321 is located below the first guide plate 310.
[0044] In an optional embodiment, the arc segments 311 of the first guide vane 310 and the second guide vane 321 have the same curvature. This allows the air from the outlet of the fan 21 to be smoothly blown out along the inner walls of both guide vanes.
[0045] In an optional embodiment, the straight segments 312 of the first guide vane 310 and the second guide vane 321 remain parallel to each other. This arrangement ensures the stability of the airflow at the outlet of the guide tube 300.
[0046] In an optional embodiment, the side plate 320 includes two opposing vertical plates 322, which are parallel to each other. The first guide plate 310, the second guide plate 321, and the two vertical plates 322 enclose a guide tube 300. The two opposing vertical plates 322 ensure that the two guide plates have the same width and the same bending angle, thereby further ensuring the smoothness of the air blown out of the guide tube 300.
[0047] As shown in the figure, in this embodiment, two guide plates are located at the top and bottom of the guide tube 300, respectively. One vertical plate 322 is connected to the edge of the two guide plates on the same side, and another vertical plate 322 is connected to the other edge of the two guide plates. Thus, the first guide plate 310, one vertical plate 322, the second guide plate 321, and the other vertical plate 322 enclose and form a cylindrical guide tube 300. The longitudinal cross-sectional shape of the guide tube 300 is quadrilateral. This arrangement can match the quadrilateral air outlet of the fan 21.
[0048] Furthermore, in this embodiment, both guide plates are curved plates, and the two upright plates 322 are flat plate structures. The top edge and bottom edge of the upright plates 322 are both curved and extend along the same curve as the top guide plate.
[0049] It is easy to understand that in other embodiments of this utility model, the guide tube 300 can also be other shapes, as long as the inner wall of the guide tube 300 can smoothly transition with the air outlet of the fan 21. This is just an example and is not limited to any specific shape.
[0050] In an optional embodiment, the upright plate 322 is perpendicular to the first guide plate 310. That is, the longitudinal section of the guide tube 300 is rectangular. This arrangement can match the air outlet of the fan 21 and the opening of the air conditioning unit 22. It is easy to understand that in other embodiments of this utility model, the upright plate 322 can also maintain an acute or obtuse angle with the guide plate, as long as the upright plate 322 and the guide plate can enclose a cylindrical guide space 301. This is just an example and is not specifically limited.
[0051] Furthermore, in an optional embodiment, the air outlet guide structure adapted to the fan also includes a first connecting plate 100, which is disposed at the inlet of the guide tube 300 and can be connected to the air outlet of the fan 21. This arrangement can ensure the structural stability at the inlet of the guide tube 300 and facilitate the connection between the guide tube 300 and the fan 21.
[0052] As can also be seen from the figure, in an optional embodiment, the air outlet guide structure adapted to the fan further includes a second connecting plate 200, which is disposed at the outlet of the guide tube 300; the second connecting plate 200 can be connected to the air conditioning unit 22. The second connecting plate 200 can both ensure the structural stability at the outlet of the guide tube 300 and facilitate the connection between the guide tube 300 and the air conditioning unit 22.
[0053] In an optional embodiment, the second connecting plate 200 is perpendicular to the outlet of the guide tube 300. That is, the second connecting plate 200 is perpendicular to the straight section 312, so that the guide tube 300 can be stably mounted on the air conditioning unit 22. It is easy to understand that in other embodiments of this utility model, the second connecting plate 200 and the guide tube 300 can also be at an acute angle or an obtuse angle; this is merely an example and is not specifically limited.
[0054] from Figure 2 As can be seen from the second aspect, this utility model provides an air conditioner, which includes an air outlet guide structure adapted to the fan as described in any of the foregoing embodiments. Such an air conditioner provides more comfortable airflow and lower noise levels.
[0055] In summary, this utility model provides an air outlet guide structure and an air conditioner adapted to a fan, which has at least the following advantages:
[0056] Improve the uniformity of airflow from the blower 21 and enhance the comfort of air conditioning in the kitchen;
[0057] Reduce the exhaust noise of the air supply fan 21 to improve the user experience of kitchen air conditioning.
[0058] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
