Control system and control method of food crushing, mixing and mixing equipment

Abstract

The invention discloses a control system and control method of food smashing, stirring and mixing equipment. The control system comprises a motor for smashing and stirring food, an overheating and overcurrent protection switch, a zero crossing signal detecting module, a container detecting switch, a zero crossing signal control module, a relay control module, a thyristor control module and a master control module. The modules are powered by a power conversion module, the master control module can control the relay control module to be communicated with the thyristor control module only when the overheating and overcurrent protection switch does not act, the container detecting switch is switched off and the zero crossing signal detecting module detects a zero crossing signal, the motor is started, the overheating and overcurrent protection switch is combined with the container detecting switch, motor starting has double protection functions, the motor is prevented from being accidentally started, a user is prevented from being hurt accidentally, and the safety of the food smashing, stirring and mixing equipment is enhanced.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a control system and a control method for food crushing, stirring and mixing equipment. Background technique [0002] With the improvement of people's living standards, more and more kitchen appliances have begun to integrate into people's lives. Due to the high frequency of use of kitchen appliances, and the kitchen is a place where children like to go, the safety of kitchen appliances is particularly important. Take the existing food crushing, mixing and mixing equipment as an example, which usually uses a motor to drive the blade to achieve food crushing, stirring and mixing. The driving voltage of the motor is generally 220V AC, so the protection of the motor is the top priority. [0003] In the prior art, overheating and overcurrent switch detection, container switch detection, etc. are generally designed, but the above-mentioned overheating and overcurrent switch detectio...

Problems solved by technology

[0003] In the prior art, overheating and overcurrent switch detection, container switch detection, etc. are generally designed, but the above-mentioned overheating and overcurrent switch detection and container switch detection are independent switch detections, which only realize the protection function through software or hardware, and do not have double protection functions. , under frequent use, the safety needs to be improved
