Abstract
A warming and cooling dual-purpose fan belongs to the technical field of the electric fan, which comprises rotating blade wind wheels, a heating unit, a filter screen, a motor, a motor support and a casing with front and rear covers; wherein, the rotating blade wind wheel is fixed on the front casing through the motor support. The utility model is characterized in that two rotating blade wind wheels are arranged, the air vent of a rotating blade wind wheel is provided with a heating unit and the air inlet is provided with a filter screen, and the air inlet and vent of the other rotating blade wind wheel have no filter screen or heating unit, and a wabbler mechanism, which can drive the casing to be wiggly leftward and rightward, is arranged in the casing. The fan can not only improve the temperature of the supplied warm air but also increase the air output when the cold air is delivered, have low noise and wide air supply range.
Description
Technical field
The utility model relates to a kind of electric fan, particularly can send the warm cool dual purpose fan of warm braw or cool breeze.
Background technique
Dim cool dual purpose fan commonly used all with single wind wheel as wind regime, by heater wind is sent again, when needs send cool breeze, just heating unit power is closed.Its structure is made up of fore shell 1, inducer 2, the electric machine support 3, back cover 4, filter screen 5, motor 6, Rotary blade type wind wheel 7, the heater 8 that are contained on the fore shell as shown in Figure 1 and Figure 2.After the energising, motor 6 drives 7 rotations of Rotary blade type wind wheel, and air sucks the back through filter screen 5 and sends by heater 8.Filter screen and heater have bigger windage, the bigger noise of friction-produced mutually between they and the inhaled air, and air quantity is big more, and noise is also big more.During the actual use of dim cool dual purpose fan, generally need to send warm braw in the winter time, this moment, temperature was lower, for obtaining higher wind-warm syndrome, required the air output of fan less.And when needs send cool breeze,, then require the air output of fan big especially in summer.But existing warm cool dual purpose fan is just closed heating unit power when sending cool breeze, and its air output is constant.If adopt the method that increases power of motor to improve air output, then because windage is bigger, and air output amplification is very little, and noise obviously increases, and electric efficiency is low.In addition, existing warm cool dual purpose fan does not have the function of vacillating now to the left, now to the right, and blowing range is narrow.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of wind-warm syndrome that can improve when sending warm braw, can increase the air quantity when sending cool breeze again, the warm cool dual purpose fan that noise is lower, blowing range is wide.
The utility model is to adopt following technological scheme to realize: the housing that this warm cool dual purpose fan comprises Rotary blade type wind wheel, heater, filter screen, motor, electric machine support and is provided with forward and backward shell, the Rotary blade type wind wheel is fixed on the fore shell by electric machine support.The utility model is provided with two Rotary blade type wind wheels, the exhaust outlet of one of them Rotary blade type wind wheel is provided with heater, intake grill is provided with filter screen, and the inlets and putlets of ventilation of another Rotary blade type wind wheel is not established filter screen and heater, but is provided with the wiggly swinging mechaism of drive shell in housing.Because the utility model is provided with two wind wheels, under the constant prerequisite of total blast volume, the required air quantity of each wind wheel just can reduce half, the also corresponding minimizing of its power of motor.When the utility model is done the use of warm braw fan,,, just can obtain the effect that improves the warm braw wind-warm syndrome, reduces noise because air quantity is less only with that wind wheel work that heater and filter screen are housed.And when the utility model was done the box fan use, then two wind wheels can be worked simultaneously, and heating unit power is closed.The cool breeze total blast volume of this moment just air quantity when sending warm braw increases about one times.Simultaneously, because wherein typhoon wheel is not provided with heater and filter screen, windage is less, thereby total noise is also low than the warm cool dual purpose fan of having now of equal air quantity.In addition, because the utility model is provided with the wiggly swinging mechaism of drive shell, thereby played the effect that increases blowing range.
The utility model is compared with existing warm cool dual purpose fan, not only have big, the dim wind-warm syndrome degree of cool breeze air quantity height, noise is low, blowing range is wide advantage, and cool breeze is evenly soft, the fan long service life.

Embodiment
With reference to Fig. 3, Fig. 4, the housing of this warm cool dual purpose fan adopts the shell construction pattern of upright post type electric fan, comprises fore shell 9 and back cover 10 etc.Be provided with two Rotary blade type wind wheels 11,12 in the housing, be fixed on the fore shell 9 by electric machine support 13,14 respectively.During installation, the motor 15,16 of two wind wheels is fixed on the electric machine support 13,14 by screw 17,18 respectively, and by nut 19,20 Rotary blade type wind wheel 11,12 is individually fixed on the axle of motor 15,16.On back cover 10 and fore shell 9, be respectively equipped with the intake grill 21,22 and the exhaust outlet 23,24 of the band net grid that use separately for each Rotary blade type wind wheel 11,12.The intake grill 22 of a Rotary blade type wind wheel 12 and exhaust outlet 24 are respectively equipped with filter screen 25 and heater 26 therein.The material of filter screen and heater is identical with existing warm cool dual purpose fan with mounting type.But the wiggly swinging mechaism 27 of drive shell is housed in the bottom of fore shell 9.The swinging mechaism 27 of present embodiment is four connecting rod swinging mechaisms, can adopt upright post type electric fan four connecting rod swinging mechaisms commonly used.In the present embodiment, Rotary blade type wind wheel 11 only send cool breeze; Rotary blade type wind wheel 12 can send warm braw, also can send cool breeze, and elder generation was with the power-off of heater 26 when it sent cool breeze when needs.When this fan was done the box fan use, Rotary blade type wind wheel 11 and 12 can be opened simultaneously, to increase air quantity; When this fan is done the use of warm braw fan, can only open Rotary blade type wind wheel 12, to improve wind pushing temperature.The controlling component 28 of this fan can adopt electric fan control modes such as mechanical type, soft-touch type or distance type commonly used.
