Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of household appliances, and in particular to an air guide component and a fan having the same. Background Art
[0002] When working, the bladeless fan forces air to blow out from a 1.0 mm wide cutout that rotates around the circular amplifier. Since the air is forced out from this circle, the wind generated by it is smoother and has a larger volume than that of an ordinary fan. Furthermore, since there are no fan blades to "cut" the air, the user will not feel the staged impact and wave-shaped stimulation, and the beautiful shape is deeply loved by consumers.
[0003] In the bladeless fan in the prior art, external air flow is sucked into the fan, and the external air flow is converted into a high-speed rotating air flow through the power system. The above-mentioned high-speed rotating air flow enters the air outlet assembly through the diffuser assembly. The above-mentioned incision is arranged in the air outlet assembly, but the air outlet assembly generally has two left and right air outlet ducts. The air inlets of the left and right air outlet ducts of the traditional bladeless fan are connected. When the high-speed air flow coming out of the diffuser assembly is diverted and enters the left and right air ducts, a part of the air flow will move axially, resulting in a collision at the air inlet of the air outlet duct to form a vortex and noise, and also reducing the air volume entering the air outlet duct. Summary of the invention
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the bladeless fan in the prior art that it is easy to cause air volume loss and generate noise at the air inlet of the air outlet component, thereby providing an air guide component and a fan having the same.
[0005] In order to solve the above problems, the present invention provides an air guide component, including a diffusion component and an air outlet component arranged on the diffusion component, the air outlet component has two air outlet ducts, and also includes: an air guide structure, which is arranged between the diffusion component and the air outlet component, and the air inlets of the two air outlet ducts are blocked by the air guide structure.
[0006] Furthermore, arc-shaped flow-dividing surfaces are formed on both sides of the air-guiding structure along the direction of airflow.
[0007] Furthermore, the arc-shaped splitter surface is arranged in parallel with the diffuser outflow surface of the air outlet assembly.
[0008] Furthermore, a transition arc surface is formed on the upper end surface of the air guide structure, and the transition arc surface is arranged parallel to the arc-shaped inner surface of the air outlet component.
[0009] Furthermore, the wind guide structure is arranged on the diffusion component.
[0010] Furthermore, a plurality of buckles and / or slots are provided on the lower end surface of the air guide structure, and a plurality of the slots and / or buckles are correspondingly provided on the upper end surface of the diffusion component.
[0011] Furthermore, a positioning column is provided on the lower end surface of the air guide structure away from the axis.
[0012] The present invention also provides a fan comprising: any one of the above-mentioned air guide components.
[0013] Furthermore, the fan is a bladeless fan.

[0017] 2. The air guide structure in the air guide assembly of the present invention has arc-shaped diversion surfaces formed on both sides along the direction of air flow.

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0033] Example 1
[0034] like Figure 1 to Figure 2 As shown, an air guide component provided in this embodiment includes a diffusion component 1 and an air outlet component 2 arranged on the diffusion component 1, the air outlet component 2 has two air outlet ducts 21, and also includes: an air guide structure 3, which is arranged between the diffusion component 1 and the air outlet component 2, and the air inlets of the two air outlet ducts 21 are blocked by the air guide structure 3.
[0035] It should be noted that the air guide assembly in this embodiment is used in a bladeless fan, and can certainly be used in other fans.
[0036] In the bladeless fan, the diffusion component 1 weakens the movement of the high-speed rotating airflow in the rotation direction and increases the work done by the axial movement of the airflow.
[0037] It should also be noted that a connecting space is formed at the air inlets of the two air outlet ducts 21 of the air outlet component 2 and the air outlet of the diffusion component 1, and the air guide structure 3 is installed in the above-mentioned connecting space, which simultaneously separates the air inlets of the two air outlet ducts 21.
[0038] The air guide structure 3 in this embodiment is an injection molded part, which is formed by an injection molding process. The above-mentioned process has the characteristics of low cost and suitability for mass production.
[0039] In this embodiment, an air guide structure 3 is provided, and the air flow coming out of the diffusion component will be guided by the air guide structure 3 into the two air outlet ducts 21, and the air guide structure 3 separates the air inlets of the two air outlet ducts 21, thereby effectively reducing the air volume loss and noise problems caused by the air flow movement at the air inlets of the air outlet ducts 21.
[0040] like Figure 1 As shown in FIG. 1 , the air guide structure 3 is arranged on the diffusion component 1. Specifically, the air guide structure 3 is approximately dumbbell-shaped, and a horizontal mounting surface is processed at one end of the diffusion component 1. The lower end surface of the air guide structure 3 is installed in contact with the above-mentioned horizontal mounting surface. Further, in this embodiment, three buckles 4 are arranged on the lower end surface of the air guide structure 3, and three slots 5 are correspondingly processed on the upper end surface of the diffusion component 1. The above-mentioned buckles 4 are common straight-arm buckles, and are directly clamped on the slots 5 during the process of pressing the air guide structure 3 downward.
[0041] In some other embodiments, the number of the buckles 4 and the corresponding slots 5 may be one, two, four, etc. The greater the number, the higher the reliability of the mounting.
[0042] In some other embodiments, a slot 5 may also be provided on the lower end surface of the air guide structure 3 , and a buckle 4 may be provided on the horizontal mounting surface of the diffusion component 1 .
[0043] In some other embodiments, when the buckle 4 and the slot 5 are used in multiple sets, the slot 5 and the buckle 4 can also be formed on the air guide structure 3 and the diffusion component 1 at the same time.
[0044] In order to facilitate installation and positioning, a positioning column 33 is formed on the lower end surface of the air guide structure 3 which is deviated from the axis. The setting method which is deviated from the axis can have a certain anti-foolproof effect to facilitate the operator's assembly. The corresponding diffusion component 1 needs to be processed with mutually compatible positioning grooves.
[0045] The following is a further explanation of how the diversion structure achieves diversion:
[0046] like Figure 1 As shown in FIG. 2 , arc-shaped flow dividing surfaces 31 are formed on both sides of the air guide structure 3 along the direction of the air flow. The arc-shaped flow dividing surfaces 31 are curved surface structures, which bend and change phases along the flow direction of the air flow to guide the air flow into the air outlet duct 21. The arc-shaped flow dividing surfaces can effectively reduce the flow resistance of the air flow, thereby effectively ensuring that the air flow velocity meets the air outlet velocity of the fan.
[0047] Furthermore, the arc-shaped diverter surface 31 is arranged in parallel with the diffuser outlet flow surface 22 of the air outlet component 2, which can ensure that the airflow flows smoothly in the air duct formed by the arc-shaped diverter surface and the diffuser outlet flow surface. According to the volume of the fan and the performance of the fan, the spacing value between the arc-shaped diverter surface 31 and the diffuser outlet flow surface 22 is generally 20mm to 40mm. In this embodiment, the spacing value between the arc-shaped diverter surface 31 and the diffuser outlet flow surface 22 is 30mm. This can ensure the effective air output while making the appearance volume of the bladeless fan more in line with the design standards.
[0048] In this embodiment, the upper end surface of the air guide structure 3 is formed with a transition arc surface 32, and the transition arc surface 32 is arranged parallel to the arc-shaped inner surface 23 of the air outlet component, which can ensure that the air guide structure 3 and the air outlet component 2 fit better.
[0049] Furthermore, there is a spacing between the transition arc surface 32 and the arc-shaped inner surface 23 of the air outlet component. The general spacing value is 1mm to 10mm, and the value in this embodiment is 5mm. The above spacing is the assembly gap between the air guide structure 3 and the arc-shaped inner surface of the air outlet component 2. The wind wheel assembly of the bladeless fan is prone to high-frequency vibration during high-speed operation. If the above spacing does not exist, it is easy to cause contact and collision between the two, thereby generating noise.
[0050] Example 2
[0051] This embodiment provides a fan, specifically a bladeless fan, including the air guide assembly described in the above embodiment 1, and has all its technical advantages, which will not be described one by one here.
[0052] The bladeless fan usually includes an air inlet assembly, and the external airflow is sucked into the fan through the air inlet assembly. The power system, the power assembly is connected to the air inlet assembly, the airflow enters the main air duct system of the bladeless fan through the air inlet assembly, and is sucked into the power system by the air inlet assembly. The airflow entering through the air inlet assembly is driven by the wind wheel in the power system to rotate to form a high-speed rotating airflow. The diffusion assembly is connected to the power system, and the high-speed airflow goes from the power system to the diffusion assembly, and is transmitted from the diffusion assembly to the air outlet assembly; the diffusion assembly works as follows: the high-speed rotating airflow weakens the movement in the rotation direction after passing through the diffusion assembly, and increases the work done by the axial movement of the airflow.
[0053] The bladeless fan in this embodiment has been tested and found to have an air output that is 10.2% higher than that of a traditional bladeless fan.
[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
