Description

Continuous low power heating control circuit for soybean milk machine

Technical field

The present invention is about a kind of soy bean milk making machine heating control circuit, especially a kind of continuous low power heating control circuit for soybean milk machine.

Background technology

Existing soy bean milk making machine adopts relay control heating, output power (heating power) can only be accomplished total power or half-power heating, generation is overflowed in that the general meeting of mashing off boiling stage power is bigger than normal, at this moment can only stop to add and reheat again after the hot standby liquid level falls after rise, again can once more overflow and stop heating, so circulation thereafter.Actual a kind of boiling and the alternating state that does not seethe with excitement of being in when this makes and to boil soya-bean milk can not be realized the effect of the abundant decomposing protein of the continuous infusion of slow fire.And easily cause during heating tube power mashing off bigger than normal and stick with paste pipe and burn, harmful and easy cleaning not, nominal power time that then preheats less than normal is long, causes wholely to do that to starch process time long.Simultaneously this mode also can shorten the relay mechanical electric life-span, and bad to the applicability of different electrical networks, becomes problem such as big along with there is heating power in the rising of line voltage.Therefore, be necessary existing soy bean milk making machine heating control mode is improved.

Summary of the invention

Therefore the object of the present invention is to provide a kind of continuous low power heating control circuit for soybean milk machine, it controls the operating voltage of heater element by trigger circuit unit controls transwitch, thereby realize the continuous low power heating, can guarantee that soya-bean milk can continuous little boiling, but can not overflow and stop heating.

According to above-mentioned purpose of the present invention, a kind of continuous low power heating control circuit for soybean milk machine is proposed, comprise heater element, output terminal connects the transwitch of heater element, the trigger circuit unit that connects the control end of transwitch, the single-chip microcomputer that connects the trigger circuit unit, the temperature sensor that connects single-chip microcomputer, the voltage detection circuit unit that connects single-chip microcomputer, the anti-overflow signal element that connects the power supply zero cross signal unit and the connection single-chip microcomputer of single-chip microcomputer, the input end of transwitch connects an electrode of power supply, and the end that heater element is not connected with transwitch connects another electrode of power supply, and single-chip microcomputer is connected with power supply by a power supply reduction voltage circuit unit.

The present invention controls the operating voltage of heater element with transwitch, according to temperature, voltage, carry out power adjustments in the mashing off different phase, be in little fluidized state in the time of can making mashing off always, make the soya-bean milk infusion abundant, emulsifiability concentration improves, the more favourable absorption of human body of using, and the power output identical to different line voltage scalable, pipe, Non-burnt pot, non-stick pan are not stuck with paste in the miniwatt heating, transwitch is not influenced by mechanical life, and comprehensive life is longer than relay, and the miniwatt mashing off is energy savings more.

Description of drawings

Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.

In the accompanying drawing,
