Pulping control circuit of cordless soybean milk machine

Abstract

The invention relates to a pulping control circuit of a cordless soybean milk machine. The pulping control circuit comprises a control branch arranged in a seat and an execution branch arranged in a machine body, and the execution branch comprises a motor, a signal detection module and an electromagnetic heating coil; and the control branch comprises an excitation winding, a resonant control module, a resonant capacitor and a controller, the resonant control module comprises IGBT and an IGBT driving loop, the excitation winding and the resonant capacitor are connected to form a high frequency resonant loop which outwardly outputs high frequency electric energy, the controller, the resonant control module and the high frequency resonant loop are sequentially electrically connected, the execution branch also comprises a magnetized winding corresponding to the excitation winding, the magnetized winding and the excitation winding are electromagnetically coupled to obtain electric energy, and the magnetized winding and the electromagnetic heating coil are electrically connected to provide electric energy required by the execution of crushing and boiling. The starting electric energy of the motor can be obtained without additionally connecting to a power plug, so a power line plug is no longer individually arranged in the cup of the soybean milk machine, thereby the hidden safety troubles comprising electric leakage, machine burning and the like are reduced.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a pulping control circuit of a cordless soybean milk machine. Background technique [0002] Soymilk machines in the prior art usually include a cup body, a machine head fastened on the cup body, a crushing device and a heating device, and the crushing device includes a motor and a crushing cutter. The crushing cutter is connected to the motor shaft of the motor and is controlled by the motor. To pulverize food for pulping. The heating device generally adopts the method of immersion electric heating tube heating or chassis electric heating tube heating. If the electric heating tube is used for heating, the electric heating tube needs to extend into the cup body, which will bring inconvenience to cleaning. It is easy to cause the problem of sticky bottom. [0003] In order to solve the above-mentioned problems caused by the existing heating methods of soybean milk machines, el...

Problems solved by technology

In the above-mentioned electromagnetic heating soymilk machine, since the motor is arranged in the machine head and the electromagnetic heating coil is arranged in the cup body or the base, it is necessary to set two power cord plugs or take a plug between the machine head and the base to supply power to the motor and the electromagnetic heating coil. Connectors are required, which makes the wiring of the external power cord of the soymilk machine complicated, which is not conducive to consumers' demand for small and light home appliances. At the same time, the structure of multiple power plugs and connectors makes the cup body of the soymilk machine difficult. To solve the waterproof problem, there will be safety hazards

In addition, in order to achieve the working control of the electromagnetic heating coil, additional control circuits need to be installed in the cup body or the seat body, making the structure in the cup body complicated and the overall cost of the soybean milk machine rising.

[0004] Regardless of whether it is an electric heating tube or an electromagnetic heating soybean milk machine, when the grid voltage is too high, the instantaneous power and speed of the motor will exceed the rated value, and there is a hidden danger of the motor being burned due to the instantaneous power of the motor. The probability of waste increases, which brings costs to industrial manufacturing. Big waste
