Abstract
The utility model discloses a variable-frequency fan belonging to a household appliance, which mainly solves the problems that the electric energy of a traditional electric fan is wasted and the rotation speed needs to be manually regulated. The structure of the variable-frequency fan comprises a fan body composed of a fan head, a support bar and a base, wherein the rear part of the fan head is provided with a transducer. The base is provided with a room temperature sensor and a control device. One side of the base is connected with a power line. The controller, the room temperature sensor, the transducer and the fan head are electrically connected with each other. The operation speed of the fan can be reasonably regulated according to the indoor temperature. The transducer can be used for changing the revolving speed of blades, reducing fan starting and stopping times and avoiding frequently starting, preventing from generating large transient currents again and again, improving an energy efficiency ratio and simplifying operation programs. Therefore, the variable-frequency fan brings convenience to the lives of people.
Description
Technical field
The utility model relates to a kind of household electric appliance, specifically a kind of frequency conversion fan.
Background technique
In order effectively to improve IAQ, reduce ambient temperature, avoid heatstroke, much human can select to use electric fan summer, utilizes physical principle to lower the temperature and relieves summer heat, and is a kind of health, energy-conservation mode; But traditional electric fan function singleness; Rotating speed control after the unlatching needs the manual tune gear to carry out; Can't select rotating speed voluntarily according to ambient temperature; When room temperature is low, select high rotating speed can waste resource, when room temperature is high, selected the slow-speed of revolution then can make the wind-force deficiency, can't effectively regulate the room temperature, make troubles to use.
The model utility content
The purpose of the utility model is to provide a kind of frequency conversion fan, and this fan has according to the characteristics of indoor environment temperature from the line translation rotating speed, the convenient use.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of frequency conversion fan; Its structure comprises the fan body that is made up of fan head, strut and base; Described fan head rear portion is provided with frequency variator; Base is provided with room temperature inductor and control gear, and a side of base is connected with power line, and described control gear, room temperature inductor, frequency variator, fan head are electrically connected.
The beneficial effect of the utility model is: owing to be provided with frequency variator at the fan head rear portion, base is provided with room temperature inductor and control gear, and fan running speed can rationally be regulated according to the height of room temperature; When room temperature and setting temperature differed big, blade can run at high speed, and the fan wobble frequency is accelerated; With the augmenter inner air flow; Let the people feel nice and cool, when room temperature during near setting temperature, the fan rotational velocity begins to descend gradually; Make room temperature keep constant, improved travelling comfort greatly; Frequency variator can change blade rotational speed, has reduced the fan on-off frequency, need not frequent starting, can not produce each instantaneous large-current, and Energy Efficiency Ratio improves, and simplifies procedures the life that is convenient for people to simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 fan head, 2 room temperature inductors, 3 frequency variators, 4 bases, 5 struts, 6 power lines, 7 control gear.
Embodiment
As shown in Figure 1.A kind of frequency conversion fan; Its structure comprises the fan body that is made up of fan head 1, strut 5 and base 4, and described fan head 1 rear portion is provided with frequency variator 3, and base 4 is provided with the room temperature inductor 2 and control gear 7 that can measure with the perception indoor environment temperature; The opening and closing of control gear 7 control fans; Regulate setting temperature in addition, a side of base 4 is connected with power line 6, and described control gear 7, room temperature inductor 2, frequency variator 3, fan head 1 are electrically connected.The microcomputer system of the control rotating speed in the frequency variator 3 realizes that through data interaction blade rotational speed adjusting and wobble frequency in the fan head 1 change.
