Abstract
The utility model relates to a bladeless electric fan, which comprises a fan base and a fan head, a motor and a cyclone accelerator are arranged inside the fan base. The bladeless electric fan is characterized in that a heating device employing heating ceramics or carbon fibers is arranged on an air duct inside the fan base, the heating ceramics or the carbon fibers are controlled by a heating circuit; furthermore, another heating device employing the heating ceramics or the carbon fibers is arranged on an inner wall of the fan head which is ring or quadrate or heart-shaped; the heating ceramics or the carbon fibers are controlled by the heating circuit. The bladeless electric fan can not only refrigerate to generate cold wind, but also heat to generate hot wind while the heating function is selected according to the need.
Description
Technical field
The utility model relates to a kind of no leaf electric fan, particularly a kind ofly selects to freeze or the no leaf electric fan of heat-production functions.
Background technique
No blade fan also makes air increase a times machine, and it can produce the cool breeze that nature continues, owing to there is not blade, can not cover dust, perhaps hurts curious children's finger.No blade fan is released in Britain on October 12nd, 2009 for the first time; The inspiration of this invention comes from the air blades hand-drying device; The principle of air blades hand-drying device is to force air to come " brush " to do water on hand through an osculum, and it is to let air in one 1.3 mm wide, otch around the annulus rotation, produce by boasting that air increases times machine.Because air is forced in this circle and produces by boasting, the air quantity of passing through can increase to 15 times, and its speed per hour can increase to 35 kilometers.
No blade fan working principle is following: 40 watts of power motor each seconds that have in the pedestal are with 33 liters air suction fan base interior; After the acceleration of cyclone accelerator; Air ventilation speed is maximum to be increased about 16 times; Via no blade fan fan headring shape epipharynx around, it gets into the fan head around near the air that power drives the fan head thereupon, and outwards blows out with the speed of 405 liters of per seconds.
As shown in Figure 1, this is the cross section of the annulus of no blade fan, is the coanda surface, can produce the physical surface of Coanda effect in fact exactly.So-called Coanda effect (Coanda Effect) is called Coanda effect again, and referring to fluid (current or air-flow) has and leave original flow direction, changes the tendency that the body surface along with protrusion flows into.When having surface friction between the body surface that fluid and it are flow through, flow rate of fluid can slow down.As long as the curvature of body surface is not too big, according to the Bernoulli's law in the fluid mechanics, the slowing down of flow velocity can cause fluid to be attracted on the body surface flowing.Simply say, run into curved surface exactly after, current or air-flow can change original moving direction, then along with curved surface flows.
This coanda surface of no blade fan can let air-flow advance along curved surface from relief opening 12 continued of coming out.The aspect that this has changed air-flow on the one hand makes it can blow to the user; On the other hand, the air-flow that blows out from relief opening can entrainment by the air-flow that it is peripheral, becomes air flow to little airflow, has played the effect of air amplifier.Here it is, and no blade fan is known as the reason place of " air multiplier ".
Its most typical characteristics are to have used in its pedestal cyclone accelerator (cyclone accelerator), and this is that item extensively is used in the technology in jet airplane engine and the automobile turbosupercharging.Utilize the technology in jet airplane engine and the automobile turbosupercharging, through the wind inlet suction air of bottom, the impeller that the inside at annulus edge hides then sprays air with circular trace, finally form one continual cold air flow.
This air flow is more steady than the wind that conventional fan produces; The air quantity that it produces is equivalent to the best fan of performance in the market; Because there is not the fan sheet to come ' cutting ' air, you can not feel to impact and stimulate, and it lets you feel nice and cool through the air stream that continues.Through frequency conversion wind speed size adjustment device, the size that makes things convenient for the user to regulate wind speed according to actual conditions, air quantity evenly increases, can surge voltage, energy consumption is low, is half energy consumption of conventional fan, and cleans more easily than common air-conditioning and fan.
The model utility content
The purpose of the utility model is, the restriction that can only freeze to existing no blade fan, thus a kind of no leaf electric fan that has heat-production functions concurrently is provided, can select refrigeration or heat-production functions as required.
Be to realize above-mentioned purpose, a kind of no leaf electric fan that the utility model provides comprises: fan base 1 and fan 2; Described fan base 1 inside is provided with motor and cyclone accelerator, it is characterized in that: the air channel in the described fan base 1 is provided with heating equipment 3.Motor is air suction fan pedestal 1 inside, after quickening via the cyclone accelerator, can select heating, again by the annular epipharynx of no blade fan around, can select further heating, it drives around power and outwards blows out after near the fan head a air gets into fan thereupon.
As a kind of improvement of technique scheme, described heating equipment 3 adopts heating pottery or graphite fiber, and described heating pottery or graphite fiber are controlled by heater circuit.
As a kind of improvement of technique scheme, described fan 2 inwall further are provided with heating equipment.Described heating equipment adopts heating pottery or graphite fiber, and described heating pottery or graphite fiber are controlled by heater circuit.
As a kind of improvement of technique scheme, described fan 2 ringwise, square or heart-shaped.
The advantage of the utility model is: the no blade fan of the utility model not only can freeze, and blows out cold wind, has heat-production functions concurrently, can select heat-production functions as required, blows out hot blast.
Description of drawings
Below, specify the embodiment of the utility model in conjunction with accompanying drawing, wherein:
Fig. 1 is the partial structurtes schematic representation of no blade fan in the existing technology;
The structural representation of the no blade fan of Fig. 2 the utility model.
The accompanying drawing sign

Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of no leaf electric fan of the utility model comprises: fan base 1 and fan 2; Described fan base 1 inside is provided with motor and cyclone accelerator, it is characterized in that: the air channel in the described fan base 1 is provided with heating equipment 3.
In this example, fan 2 be an annular fan head, and heating equipment 3 adopts heating ceramic.Motor is air suction fan pedestal 1 inside, after quickening via the cyclone accelerator, can select heating, again by the annular epipharynx of no blade fan around, can select further heating, it drives around power and outwards blows out after near the fan head a air gets into fan thereupon.
It should be noted last that above embodiment is only unrestricted in order to the technological scheme of explanation the utility model.Although the utility model is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; The technological scheme of the utility model is made amendment or is equal to replacement; The spirit and the scope that do not break away from the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
