1-Fig. 7 describes soy bean milk making machine of the present invention in detail with reference to the accompanying drawings.
Soy bean milk making machine according to an embodiment of the invention, comprises staving 101, grinder 103, pulverizes motor 105, heater 107, agitator 109, stirring motor 111 and regulating circuit.
Shown in seeing figures.1.and.2, have a barrel chamber in staving 101, this barrel of chamber can be used for putting pulping materials, and the top in bucket chamber is opened wide.Staving 101 can be the cup-shaped of a general cylindrical, can certainly form for example cardinal principle square column type of other shapes.The top of staving 101 is provided with head 102, and head 102 and staving 101 adopt the mode of active link, and for example head 102 can buckle the top at staving 101.
It is interior for pulverizing the pulping materials being contained in staving 101 that grinder 103 is arranged on staving 101, pulverizes motor 105 and be connected with grinder 103, to drive grinder 103 to rotate.Pulverize motor 105 and can be arranged in head 102, the output shaft of pulverizing motor 105 can directly be connected with pulverizing motor 105, or also can be connected by grinder 103 axles, moreover also can be connected by shaft coupling or other transmission mechanisms.
Grinder 103 can be beater bar, and this beater bar preferably adopts stainless steel material to make, and can improve like this life-span of grinder 103, simultaneously convenient cleaning.
Heater 107 is for heating the raw soya-bean milk in staving 101, heater 107 can be located at the interior direct heating that contacts with raw soya-bean milk of staving 101, certainly, heater 107 also can be arranged on staving 101 outsides, for example, be arranged on the outer bottom or sidewall of staving 101.Heater 107 can be heating tube, can certainly be heating plate or any device that can heat the slurrying liquid holding in staving.
Agitator 109 is arranged in staving 101, for stirring.Stirring motor 111 is connected with agitator 109, to drive agitator 109 to rotate.As shown in Figure 6 and Figure 7, regulating circuit is connected with stirring motor 111 and is configured for regulating the input voltage of stirring motor 111.By this regulating circuit is set, thereby can regulate as required the input voltage of stirring motor 111, and then realize the adjusting of stirring motor 111 output speeds.
According to the soy bean milk making machine of the embodiment of the present invention, by the regulating circuit being connected with stirring motor 111 is set, thereby make the output speed of stirring motor 111 adjustable, so just can control the input voltage that mixing speed for example turns down stirring motor 111 reduces with the output speed that makes stirring motor 111, so that raw soya-bean milk is stirred slowly, thereby can greatly improve the phenomenon that is sticking while heating infusion raw soya-bean milk, also help simultaneously and improve the concentration that makes soya-bean milk.
Wherein, the regulative mode of the input voltage of stirring motor 111 has multiple, below by three kinds of modes describing in detail wherein.
According to one embodiment of present invention, regulating circuit is to cut a wave circuit, that is to say, the voltage of supplying with stirring motor 111 can change by Wave-cutting method.Further, cut wave circuit input voltage is cut to ripple, and a section ripple dutycycle is 5%-80%.According to one embodiment of present invention, this section of ripple dutycycle can be 10%-50%.Further, according to another preferred embodiment, this section of ripple dutycycle can be 10%-30%.
Thus, can obtain the input voltage of required stirring motor 111 thereby cut by control the dutycycle that wave circuit cuts ripple to input voltage, thereby obtain the output speed of required stirring motor 111.
Shown in Fig. 3-Fig. 5, wherein input voltage is UO, by Wave-cutting method, this voltage U 0 is reduced to U2, thereby realizes the control of stirring motor 111 rotating speeds.As shown in Figure 3, this voltage waveform is less than 10% by intercepting, and as shown in Figure 4, this voltage waveform is cut ripple 50%, as shown in Figure 5, can cut ripple by offset of sinusoidal input voltage waveform, the effect reducing to obtain motor input voltage.
According to another embodiment of the invention, as shown in Figure 7, this regulating circuit comprises resistance 114 and the first change-over switch 116, wherein the first end of resistance 114 (for example left end) is connected to stirring motor 111, the first end (for example left end) of the first change-over switch 116 for example, is connected or is directly connected with stirring motor 111 with second end (right-hand member) of resistance 114, and second end (for example right-hand member) of the first change-over switch 116 is connected with for example external input voltage (U0).
In other words, sort circuit structure is equivalent to be arranged in parallel a dividing potential drop branch road 112 on the basis of conventional voltage input circuit.On this dividing potential drop branch road 112, be provided with divider resistance 114, the first change-over switches 116 for controlling the input voltage of stirring motor 111.
It should be noted that, the obvious understanding of those of ordinary skill can be arranged in parallel the dividing potential drop branch road 112 more than 2 on hydraulic circuit at normal stirring motor, on this dividing potential drop branch road 112, be respectively arranged with different resistance 114, and realize the switching input of input voltage by switching the first change-over switch 116.
According to still a further embodiment, as shown in Figure 6, regulating circuit comprises at least one power supply and the second change-over switch 115, wherein this at least one power supply provides input voltage for soy bean milk making machine, the first end (for example left end) of the second change-over switch 115 is connected with stirring motor 111, and second end (for example right-hand member) of the second change-over switch 115 is connected with a power supply at least one power supply.
In other words, in this embodiment, as shown in Figure 6, can be by different voltage U 2, U0 is provided, and realize the change of the input voltage of stirring motor 111 by the switching of the second change-over switch 115.It should be noted that, the obvious understanding of those of ordinary skill can provide the input voltage more than 2, and realizes the variation of input voltage by switching the second change-over switch 115.
In brief, want to change the output speed of stirring motor 111, the equivalent voltage that can input to stirring motor 111 by change is realized, and can not be interpreted as a kind of restriction of the present invention above taking Wave-cutting method etc. as example explanation.Be understandable that, can change the method for the input voltage of stirring motor 111 for other, within all falling into protection scope of the present invention.
According to one embodiment of present invention, as shown in Figure 1, grinder 103 is same parts with agitator 109, and pulverizing motor 105 is same parts with stirring motor 111, that is to say, grinder 103 had both had crushing function, also possessed agitating function simultaneously.In these some embodiment, grinder 103 is removably fixedly connected with pulverizing motor 105, and the assembling that facilitates like this grinder 103 and pulverize motor 105 also can be convenient for changing grinder 103 simultaneously in the time that grinder 103 damages.
Certainly, the invention is not restricted to this, in other embodiments of the invention, as shown in Figure 2, agitator 109 and grinder 103 can be also independent parts, now pulverizing motor 105 and stirring motor 111 is also two independent motors, for example, in one of them example of the present invention, this agitator 109 can be arranged on separately the inner bottom part of the staving 101 of soy bean milk making machine, stirring motor 111 can be arranged on the outer bottom of staving 101, and the output shaft of stirring motor 111 can extend in staving 101 and be connected with agitator 109 through the diapire of staving 101.
Further, in this embodiment, as shown in Figure 2, the central axes of the pivot center of agitator 109 and staving 101, can improve the stirring efficiency of agitator 109 like this, makes agitator 109 can stir better the raw soya-bean milk of staving 101.
As shown in Figure 2, in this embodiment, the equivalent diameter of agitator 109 is not less than the equivalent diameter of grinder 103.Optimal way is the equivalent diameter that the equivalent diameter of agitator 109 is greater than grinder 103, can further improve like this stirring efficiency.
