Description

The ultra-thin household electric fan
Technical field
The utility model relates to air bells conditioner, particularly relates to the domestic electric fan with superthin structure.
Background technique
The prior art electric fan is to drive air with blower fan, and air is sent outside the machine with certain speed, impels indoor air flows, gives feel cool.Want to obtain certain ventilation effect of enjoying the cool, the wind speed of blower fan and air quantity must reach certain value, in other words must have certain power, and the size of blower fan is the deciding factor of decision air conditioning fan complete machine size.Existing electric fan all is to use a big blower fan, minimum its separate unit power of fan of mini fan is also more than ten watts, axial dimension is more than 50 millimeters, diameter is also very big, so existing these blower fans all are ac power supplys (example that is not included in " domestic electric fan " that place only refers to of open-air usefulness) that drive, and all these electric appliances all adopt inner rotor motor, and fan blade is with respect to the stator movement of outer ring, disconnected from each other, so blower sizes is very big.Owing to be subjected to the restriction of blower sizes, the size of existing electric fan is all very big, thickness size is little less than 100 millimeters, not only floor space is big, very heavy again, and it is many to consume plastics and metallic material, and the copper cash consumption of its AC motor is surprising especially, in addition, existing air conditioning fan power of fan is generally all more than 50 watts, all be internal rotor AC motor or the motor with cup rotor driving with the single-phase capacitance phase-splitting, this type of motor volume is big, efficient is low, and power consumption is big, its copper cash consumption is surprising especially, such resource greatly consumes and has restricted development and national economy, simultaneously, also causes the manufacture cost of air conditioning fan very high.Because their popularity rate is high again, also brings white elephant to the Consumer.For reducing axial dimension, extremely individual other electric fan design proposal is arranged together, but because of it is that a plurality of independently electric fans are are mechanically composed and laid out together, cost is high all the better a plurality of small fan simple combination.On the other hand, the control performance of Wechselstrommotor is very poor, the speed change difficulty, and the used Wechselstrommotor of air conditioning fan is general maximum can only realize three-step timing, is difficult to realize stepless speed regulation.AC motor is used the 220V civil power, and Security is also very poor, must adopt reinforced insulation and safety measure, has also further increased cost.
Prior art has a kind of low power ultrathin axial-flow blower, and its motor is the permanent magnet DC brushless motor of external rotor type, is commonly used for computer main, and the cooling fan of instrument, instrument, sees Fig. 9.This series products is because dexterously the impeller endoporus of axial-flow leaf, that is wheel hub directly is sleeved on the motor external rotor magnet ring, thereby makes the axial thickness of impeller overlapping with the axial length of motor, reduced the axial dimension of described blower fan greatly.Typical case's representative of this type of ultrathin axial-flow blower has, the YM series dc brushless motor of the permanent safe Electronics Co., Ltd. of the AD of commercially available Xiexi Motor Co., Ltd. series dc brushless motor and Shenzhen China, comprise 6 volts of direct currents, 12 volts ... .. is until the blower fan of 42 volts multiple voltage grade.
Model utility content the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of ultra-thin household electric fan, and this domestic electric fan structure is frivolous, the consumptive material little power consumption, and fabricating cost is low, saves social resources.
The utility model solve the technical problem can be by realizing by the following technical solutions:
Design, a kind of ultra-thin household electric fan of use comprise support and the body that is mounted thereon, and this body comprises housing again and be installed in housing interior blower fan and electric component that described housing is the tablet housing structure; Blower fan in the described housing is to comprise at least two parallel connections or the fan assembly of the ultrathin axial-flow blower that is electrically connected in series, and described each ultrathin axial-flow blower is arranged on same the plane in or is arranged in crossing obtuse-angulate two planes; Described ultrathin axial-flow blower comprises aial flow impeller and outer rotor motor, the wheel hub of this aial flow impeller and the coaxial one that is fixed into of the external rotor of outer rotor motor.
Described fan assembly comprises four parallel connections or the ultrathin axial-flow blower that is electrically connected in series, and these four ultrathin axial-flow blowers are matrix and are arranged in juxtaposition.
Be fixed with rotating shaft under the described body, the support middle part has and rotating shaft jack movingly; Described base inner is equipped with reducing motor, and the output shaft of this reducing motor is connected with described rotating shaft by connecting rod.
Described body central authorities, enclosure interior are equipped with reducing motor; The exhaust outlet place of described blower fan, also be the front side of described housing, be provided with the blade-rotating plate of band inclination grid, the output shaft of this blade-rotating plate and described reducing motor is connected and fixed.
Also comprise vertical rod, this vertical rod lower end assigns in the support, and described fuselage interior is fixed with reducing motor, and the reducing motor output shaft is connected with the vertical rod upper end by connecting rod; Described fan assembly comprises that three upper and lower arrangements are the ultrathin axial-flow blower of perpendicular yi word pattern.
Described body is less than or equal to 0.25 along the ratio of fan assembly axial thickness and the width of body.
Described outer rotor motor is the permanent magnet brushless direct current motor, drives with the direct current power of 42 volts or its following voltage.
The single-machine capacity of described axial-flow blower is less than or equal to 10 watts, and each axial-flow blower in the described fan assembly has same power or different capacity.
Compare with prior art, the technique effect of the utility model ultra-thin household electric fan is:
1, fan assembly is the core component of domestic electric fan, its thickness, size is to complete machine size and weight and how many decisive role of consumptive material of electric fan, the utility model adopts the fan assembly of the ultrathin axial-flow blower that comprises at least two parallel connections or be electrically connected in series, the volume of the air bells conditioner of same specification (being same air output) is greatly reduced, weight greatly alleviates, small product size and weight can reduce more than 70%, correspondingly, the plastics of accessories such as the housing of product, metallic material consumption also reduces and can reach more than 70%, significantly reduced the fabricating cost of product, save social resources, promote development and national economy, simultaneously, the volume storage fee that also reduces greatly little and in light weight is used;
2, the blower fan of prior art electric fan is all used single-phase capacitance split-phase motor or motor with cup rotor, these electric efficiencies are very low, even have only tens percent, use permanent-magnet brushless DC electric machine instead after, efficient improves significantly, makes the power consumption of whole blower fan save more than 60%;
3, can save a large amount of strategic materials: the brshless DC motor that produces same air quantity is saved more than 90% than existing AC motor steel, and copper material is saved more than 80%;
4, ease of use improves greatly: existing product is general maximum can only realize three-step timing, and this programme dc fan can in very large range be realized stepless speed regulation;
5, safety in utilization improves greatly: this programme direct current generator adopts the DC power supply far below special lower security voltage 42V, outside the scope that mandatory safety certificate contains, the user does not have security concerns extremely, also can be producer and saves considerable safety certificate expense.
