A noise filter like an input reactor is connected between the input end of the frequency inverter control module and the external power supply. The adoption of the soft ice cream machine that achieves the variable frequency control of the utility model can reduce noise, increase starting torque and smooth operation, expand the scope of speed adjustment, achieve the stepless speed adjustment and intelligent fuzzy control, and save the energy.
Description
Technical field
The utility model relates to a kind of food machinery, especially a kind of ice cream maker.
Background technology
Soft ice-cream machine in the market, mostly with single-phase double value capacitor asynchronous motor as the core drive source, it has a main winding, an auxiliary winding.The electric capacity of a 30uF/400v of auxiliary winding serial connection, again with main winding and together, power supply produces rotating excitation field, starter motor work by splitting phase.After rotating speed reaches certain value,, auxiliary winding is disconnected by centrifugal switch.Meanwhile, auxiliary winding and a 150uF/250v capacitances in series become shunt excitation operation winding together, enter normal operating conditions.Its shortcoming is: because the defective on manufacturing process, the distribution of its space magnetic field is heterogeneous, can make armature spindle shake up and down along the footpath, is easy to generate magnetic gap, increases noise.And the loading moment imbalance, rotating torque is little, and speed adjustable range is narrow, and efficient is low, and is bigger to electric network pollution, can not satisfy the widespread demand that AC speed regulating is used.Also have operating current big, when particularly the ice cream slurries were made the ice cream state, the motor centrifugal switch was very easily damaged by arc erosion, can't frequent starting control.Easily burn simultaneously startup electric capacity and operation electric capacity, even damage asynchronous machine.
Monophase machine can not be regulated because the rotating speed height in addition, can cause colloid, the curing agent of ice powder in blending together to be pulverized, and easily causes ice cream to adhere to layering, and adhesion strength is not enough, can't moulding.Even moulding, the retention time falls short of, and profile is not attractive in appearance yet.
Summary of the invention
The technical problems to be solved in the utility model is to overcome that traditional ice cream machine noise is big, speed adjustable range is narrow, easily cause ice cream to adhere to layering, adhesion strength is not enough, even can't fall short of the moulding moulding retention time, the inaesthetic defective of profile, and efficient is low,, operating current big to electric network pollution big, the motor centrifugal switch very easily by arc erosion damage, can't frequent starting control, easily burn the defective that starts electric capacity and operation electric capacity even damage asynchronous machine.
The utility model provides a kind of soft ice-cream machine of realizing VFC for this reason, comprise motor, control module, display module, wherein motor is a three phase squirrel cage induction motor, is connected with frequency transformer control module between three phase squirrel cage induction motor and external power supply.
As a kind of improvement of the present utility model, between the input of frequency transformer control module and external power supply, be connected with noise filter, for example the input reactance device.
Adopt the soft ice-cream machine of realization VFC described in the utility model, can reduce noise, increase staring torque, operate steadily; Widen speed adjustable range, realize stepless speed regulation, Intelligent Fuzzy Control, the saving energy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Accompanying drawing 1 is a kind of VFC wiring diagram of realizing the soft ice-cream machine of VFC described in the utility model.
Accompanying drawing 2 is the panel schematic diagram of the frequency converter of a kind of soft ice-cream machine of realizing VFC described in the utility model.
Label is respectively shown in the figure:
The 1st, frequency transformer control module, the 2nd, master board, the 3rd, display board, the 4th, input reactance device, the 5th, power supply, the 6th, three phase squirrel cage induction motor.
The specific embodiment
As shown in Figure 1, a kind of soft ice-cream machine of VFC of realizing described in the utility model is made up of frequency transformer control module 1, master board 2, display board 3, input reactance device 4, power supply 5 and three phase squirrel cage induction motor 6.Power supply 5 connects frequency transformer control module 1, master board 2 by the trunk electric wire.Between power supply 5 and frequency transformer control module 1, can also connect input reactance device 4.The output of frequency transformer control module 1 connects three phase squirrel cage induction motor 6.Master board 2 outputs connect display board 3.
When load carrying, frequency transformer control module 1 must be transferred to below the fundamental frequency 50HZ, and carrier frequency is transferred to about 10KHZ, allows frequency transformer control module 1 be in the constant force square way of output.If surpass fundamental frequency 50HZ, when ice cream became the cake shape, resistance sudden change motor torque deficiency was easy to generate noise.These noises can exert an influence to equipment and near instrument and meter, and its degree is relevant with the multiple factors such as antinoise interference performance, wiring environment, arrangement distance and earthing method of frequency transformer control module 1 and equipment.When the shared same power-supply system of external equipment and frequency transformer control module 1, the noise that frequency transformer control module 1 takes place also can contrary power line direction be propagated, and make other external equipments produce misoperation.The measure that can take noise filter is installed at the input of frequency transformer control module 1 prevents.
As shown in Figure 2, the operating procedure of frequency transformer control module 1 is:
1, enters editing mode with the PRG key;
2, defined parameters;
3, get back to stopped status with the PRG key;
4, with 1 closure of the K switch between FWD and the COM, motor entry into service;
5, regulating frequency value;
6, disconnect the K1 K2 that closes, motor antiport;
7, disconnect K1, K2, frequency transformer control module 1 slows down and stops;
8, outage.
