Abrasive soymilk grinder and stalling-prevention method thereof

Abstract

The invention belongs to the field of kitchen small appliances, particularly relating to a soymilk grinder and more particularly to an abrasive soymilk grinder and a stalling-prevention method thereof. The soymilk grinder comprises a processor unit, an input control unit, a motor control unit, a detection unit, a motor regulation and control unit and a heating unit. The method of speed-regulation soymilk grinding comprises the following stages of: a) a feeding stage, b) a liquid level detection stage, c) a preheating stage H1, d) a soymilk grinding and stalling prevention stage, e) a heating stage H2, and f) a boiling stage. The abrasive soymilk grinder and the stalling-prevention method thereof in the invention realize the automatic blocking prevention through the current detection, increase the safety performance, and are capable of detecting repeatedly and cyclically and automatically discharging the blocking materials, are convenient for use and realize the unmanned soymilk preparing process.

Description

technical field [0001] The invention belongs to the field of small kitchen appliances, and in particular relates to a soymilk maker, in particular to a soymilk grinder and an anti-blocking method thereof. Background technique [0002] Soymilk machine has been widely used by people. Grinding soya-bean milk machine to grind food, with its low speed, low noise and other related advantages, will become a new direction for the development of soya-bean milk machine in the next step. From the current soymilk machine in the process of grinding food, it is found that due to the hardness of the food, if the fruit and vegetable fibers are too thick or the cut pieces are too large, the load may be greater than the rated power of the motor, which will easily cause the motor to stall, thereby burning the motor or causing the transmission Institutional damage. From the known soymilk machine, there is no related anti-blocking technology. Find related anti-blocking technology on the juice ...

AI Technical Summary

Problems solved by technology

[0003] Although the above two technologies have achieved the purpose of protecting the motor and preventing stalling, there are still many deficiencies: method 1 needs to be reinstalled after starting the protection, and the clutch structure can be restored before it can be used again, which brings problems to the user. It is very inconvenient; Method 2: During the use of the product, someone must stand by and find that the motor is blocked. Manual operation is required to effectively solve the problem of motor blocking. This does not completely solve the hidden danger of stalling.

[0004] The utility model with the authorized announcement number "CN201479858U" has published a patent called "Bladeless Axial Flow Soymilk Maker", which is a pulverizer installed on the motor shaft, and a pulverizer fixed on the machine head and located outside the pulverizer. There are discharge holes on the pulverizer, and there are pulverizing grooves on the wall of the pulverizing body and the inner wall of the pulverizer, and the edges are relatively sharp. This structure realizes the circular grinding of food materials, and the pulverizing effect is improved to a certain extent compared with the previous design; but this structure Only close to the pulverizing groove on the crushing body, the suction generated by the agitating water flow drives the food into the pulverizer. When pulverizing larger food, it will encounter the problem of insufficient suction, and when encountering hard food, it will not be completely pulverized into small particles in time. When it is used, the food will be stuck between the pulverizer and the pulverizer, which will seriously affect the life of the motor and the performance of the whole machine; and the pulverizer relies on the sharp edges of the protrusions between adjacent pulverizer grooves to Increase the effect of crushing, this sharp edge is easy to be worn

[0005] The pulverizing grooves of this structure are distributed spirally or linearly along the outer wall at equal or unequal intervals on the pulverizer or pulverizer, which is unfavorable to realize pulverization from coarse to fine, and it is not installed on the motor shaft. The anti-blocking device has no anti-blocking measures for the motor. When the hard material is crushed, it is easy to get stuck and cause the motor to overheat, which will cause the motor to burn out or bring a more serious threat to kitchen safety.
