Pulp control method for soybean milk machine and soybean milk machine

Abstract

The invention provides a soymilk machine pulp control method and a soymilk machine corresponding to the control method. The solution provided is to add an RC control detection circuit to the main control unit of the soymilk machine and combine it with the control method to effectively judge whether the soymilk machine is a continuous system. According to the judgment results, the pulping process is optimized and controlled to ensure the normal operation of the motor and to protect the motor from overheating. Moreover, the normal execution of the pulping procedure will not be affected when the corresponding measures for overheating protection are carried out, the reliability and stability of the pulping are ensured, and the slurry with stable quality can be obtained. It can increase the service life of the soybean milk machine and improve the user experience at the same time.

Description

technical field [0001] The invention relates to the field of small household appliances, in particular to a soymilk maker, and in particular to a soymilk maker's pulp control method and a soymilk maker. Background technique [0002] The main functional circuits of the soymilk machine are the motor circuit and motor drive circuit for crushing raw materials; and the heating circuit and heating drive circuit for heating the slurry. During use, the motor circuit and the heating circuit often work at the same time or alternately. The motor itself will generate heat during operation, and at the same time, when the slurry is heated, heat will also be transferred to the location where the motor is installed. The motor will be prone to failure after exceeding a certain temperature range, so it is necessary to monitor and control the temperature of the motor and / or the circuit board to ensure that the continuous working motor has sufficient cooling time for heat dissipation.

AI Technical Summary

Problems solved by technology

[0004] First of all, the temperature sensor is used to realize the detection method, which is easily affected by the external environment, resulting in a large deviation between the detection result and the actual situation

It is not advisable to configure too many temperature sensors. They can only monitor local temperatures. If a certain part is close to a heat source or exposed to sunlight for a period of time, local overheating may occur. Monitoring by temperature sensors may cause false alarms

When there is no need to stop the cooling, the cooling is forced to waste the user's time

It is also possible that some parts of the soymilk machine are close to the cold source, or the heat dissipation conditions are relatively good, and the temperature at the monitoring position is within the suitable working range, but other parts may have been overheated, and the monitoring response is not timely, and the cooling may not be controlled accurately and in time, resulting in the motor malfunctioning run or even fail

[0005] In addition, the temperature sensor is an attached component, and the temperature sensor that can sensitively monitor the temperature of the motor is expensive, which will increase additional costs, increase the overall cost of the product, and reduce the competitive advantage of the product

[0006] At the same time, the temperature sensor must be installed close to the motor, otherwise it is difficult to accurately monitor the corresponding temperature changes. In this way, the temperature sensor must be installed together with the motor, which means that the corresponding installation space and protection must be provided in the supporting structure of the soybean milk machine, such as the housing. Space, this requirement must be considered when making the overall design. Once the position of the motor needs to be adjusted, the relevant adaptive adjustment of the housing must also be considered, which will not be conducive to the integration and compact design of the product.

And it reduces the generalization degree of each component of different types of products, which is not conducive to industrial application

[0007] On the other hand, the existing pulping procedures are all set according to different requirements such as the type of raw materials and the desired taste of the finished product. On the premise of ensuring the normal operation of the motor, it is necessary to ensure that the pulping process strictly follows the preset procedures. Execution, otherwise, it will affect the taste or quality of the prepared slurry, and affect the experience of use
