Embodiment one
The structural representation of the ice cream maker control circuit that Fig. 1 provides for the utility model embodiment one, as shown in Figure 1, the ice cream maker control circuit that the present embodiment provides, comprising: moment of torsion detection components, controller, refrigerating plant, stirring motor and confession user input the input media of soft durometer parameter;
The test side of described moment of torsion detection components is connected with described stirring motor, for detecting the torque signal of described stirring motor output terminal; The output terminal of described moment of torsion detection components is connected with described controller, so that described torque signal is sent to described controller;
Described controller is connected with described input media, refrigerating plant and stirring motor respectively, for controlling startup and the stopping of described refrigerating plant and stirring motor according to described soft durometer parameter and torque signal.
Particularly, refrigerating plant can comprise the parts such as compressor or semiconductor cooler (Thermoelectric Cooler is called for short TEC), specifically can be arranged on the outside of the refrigeration barrel for accommodating ice cream materials, for lowering the temperature to raw material; Stirring motor can drive stirring vane to stir raw material, one is by stirring, the strengthening of refrigeration barrel cold can be conducted to raw material refrigeration, two is raw material can be stirred and merge partial air to make raw material more fluffy, and the ice-cream mouthfeel produced is better; Controller is connected respectively with refrigerating plant, stirring motor, for controlling startup and the stopping of refrigerating plant and stirring motor.
In the prior art, the time-controlled mode of the many employings of controller, under acquiescence different temperatures, the manufacture of ice cream time is all identical, but in actual applications, Production Time, variation with temperature was widely different, such as, when ambient temperature is 25 DEG C, the time that ice cream reaches a certain hardness is 1 hour, and when environment temperature is 30 DEG C, because ambient temperature is higher, the initial temperature of ice cream materials is larger, therefore need more refrigerating capacity, it is that the ice cream made for 1.5 hours just can reach same hardness that refrigerating plant works possibly.Visible, according to timing mode, ice cream maker is controlled, be difficult to determine suitable timing, the ice cream hardness produced when temperature is higher is softer, be difficult to meet consumers' demand, equally, the Liquid Concentration of ice cream materials and solid contents also can have an impact to ice-cream soft durometer.
For this problem, ice cream maker in the present embodiment is provided with moment of torsion detection components on the original basis, because stirring motor controls stirring vane, ice cream is stirred, ice-cream hardness directly can be reflected as the torque value of stirring motor, the moment of torsion of motor is larger, illustrate that ice cream is harder, the moment of torsion of motor is less, illustrate that ice cream is softer, therefore, the torque signal of moment of torsion detection components to stirring motor can be utilized to detect, torque signal is the signal that directly or indirectly can reflect stirring motor output torque, such as, can be the working current of stirring motor or be directly the output torque of stirring motor.The test side of moment of torsion detection components is connected with stirring motor, the output terminal of moment of torsion detection components is connected with controller, described torque signal can be sent to described controller, the current output torque of stirring motor is obtained by torque signal, regardless of ambient temperature, the concentration of ice cream materials how, as long as reach predetermined torque, just illustrate that ice cream reaches default hardness, controller can control stirring motor or refrigeration plant stops or stopping after delay certain hour.
In addition, ice cream maker in the present embodiment is also provided with the input media inputting soft durometer parameter for user, the ice cream hardness that soft durometer parameter representative of consumer is expected, because different users has different tastes, it is also different to the demand of hardness, arranges the personal needs that input media can meet user further.Except soft durometer parameter, user can also directly control ice-cream startup, stopping by input media or stop after postponing the regular hour.Input media is also connected with controller, and soft durometer parameter and torque signal, together as the input of controller, realize the startup to refrigerating plant and stirring motor and stopping.
Particularly, different soft durometer parameters can represent different predetermined torques, when the hardness number that user selects is larger, predetermined torque value is higher, and when the hardness number that user selects is less, corresponding predetermined torque value is also lower, obviously, when user expects that ice cream hardness is softer, after reaching lower predetermined torque, controller can control stirring motor and refrigerating plant quits work.In real work, first controller can receive the soft durometer parameter that user is inputted by input media, according to the corresponding predetermined torque of this soft durometer parameter acquiring, and detect the torque signal of moment of torsion detection components output, when the torque value that torque signal is corresponding reaches predetermined torque, illustrate that ice-cream hardness reaches the requirement of user, can stirring motor be controlled and refrigerating plant quits work.
It should be noted that, in order to ensure the safety of stirring motor, predetermined torque should be not more than the peak torque of stirring motor, damages to avoid stirring motor.If ice cream hardness when stirring motor reaches peak torque can't meet the demand of user to hardness, can after stirring motor stops, control refrigerating plant works on, because the refrigerating capacity of the refrigerating plant of delay working constantly inputs to ice cream, therefore, ice-cream hardness constantly increases, and the time of time delay also can be inputted by input media by user, adjusts according to the taste of oneself to facilitate user.

Wherein, stirring motor can be direct current generator, and electric current and the moment of torsion of direct current generator have one-to-one relationship, therefore, can obtain the moment of torsion of stirring motor by detecting electric current.In the ice cream maker control circuit that the present embodiment provides, moment of torsion detection components can comprise sample resistance and voltage check device, sample resistance is connected in series with stirring motor, namely one end is connected with stirring motor, the other end is connected with power supply, voltage check device is in parallel with sample resistance, by measuring the voltage of sample resistance, namely can obtain the working current of stirring motor.Controller, according to the working current of stirring motor and the soft durometer parameter from input media reception, controls unlatching and the stopping of refrigerating plant and stirring motor.Power supply is used for powering for refrigerating plant, stirring apparatus and controller.Controller can be realized by switch such as relay for the control of refrigerating plant and stirring motor, be serially connected with switch respectively between stirring motor and power supply and between refrigerating plant and power supply, controller turns on and off by gauge tap the control realized refrigerating plant and stirring system.
