Meanwhile, due to the two overflowing-prevention probes are arranged and triggered at different heights, grading heating control of the heater is achieved, and a better heating effect is achieved.

Description

A kind of dual anti-overflow control system of soy bean milk making machine
[technical field]
The utility model relates to a kind of dual anti-overflow control system of soy bean milk making machine.
[background technology]
Existing soy bean milk making machine is all that individual layer is anti-overflow, anti-overflow probe in detecting is malfunctioning when occurring, and pulping program is also in operation, heat-generating pipe is in heating, can cause the uncontrollable heat-generating pipe stopped heating of MCU, cause the water in soy bean milk making machine seethe with excitement and produce to excessive air pressure, can cause life safety, therefore, be necessary to solve as above problem.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, a kind of dual anti-overflow control system of soy bean milk making machine is provided, it can in the situation that the malfunctioning probe of another anti-overflow module that can also utilize of the probe in detecting of an anti-overflow module carry out anti-overflow control detection, output signal to the MCU controller and control.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of dual anti-overflow control system of soy bean milk making machine, include the MCU controller, be connected with motor on described MCU controller and stir drive circuit, heater, input key, described MCU controller also is connected with for anti-overflow the first anti-overflow module and the second anti-overflow module of soy bean milk making machine slurry foam height detection.
Also be connected with buzzer and display module on described MCU controller.
The described first anti-overflow module includes resistance R 11, described resistance R 11 1 ends are connected with the MCU controller as the signal output part of the first anti-overflow module, resistance R 11 other ends are connected with resistance R 12 and capacitor C 11, described resistance R 12 other ends are connected with input voltage, capacitor C 11 other end ground connection are connected with for induction slurry foam whether arrive first probe of specifying sensed position on the tie point of described resistance R 11 and resistance R 12.
The described second anti-overflow module includes resistance R 21, described resistance R 21 1 ends are connected with the MCU controller as the signal output part of the second anti-overflow module, resistance R 21 other ends are connected with resistance R 22 and capacitor C 21, described resistance R 22 other ends are connected with input voltage, capacitor C 21 other end ground connection are connected with for induction slurry foam whether arrive second probe of specifying sensed position on the tie point of described resistance R 21 and resistance R 22.
Be that appointment sensed position that the second probe of described the second anti-overflow module arranges is on the appointment sensed position of the first probe of the first anti-overflow module.
The beneficial effects of the utility model are: the Anti-spill with two anti-overflow modules; can carry out two re-detections to the slurry foam; can prevent from causing starching the excessive generation of foam because probe in detecting is malfunctioning; accomplish better protection; and setting and triggering due to two anti-overflow probe differing heights; the classification that has realized heater adds thermal control, reaches better heating effect.
[description of drawings]
Fig. 1 is circuit of soymilk machine structure chart of the present utility model.
Fig. 2 is electric principle schematic of the present utility model.
[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
As shown in Figure 1, a kind of dual anti-overflow control system of soy bean milk making machine, include MCU controller 1, be connected with motor on described MCU controller 1 and stir drive circuit 2, heater 3, input key 4, described MCU controller 1 also is connected with for anti-overflow the first anti-overflow module 7 and the second anti-overflow module 8 of soy bean milk making machine slurry foam height detection.
Also being connected with buzzer 5 and display module 6 on described MCU controller 1 shows to carry out audible alarm and information.
The described first anti-overflow module 7 includes resistance R 11, described resistance R 11 1 ends are connected with MCU controller 1 as the signal output part of the first anti-overflow module 7, resistance R 11 other ends are connected with resistance R 12 and capacitor C 11, described resistance R 12 other ends are connected with input voltage, capacitor C 11 other end ground connection also are connected with the first probe 71 that whether arrives sensed position for induction slurry foam on the tie point of described resistance R 11 and resistance R 12.
The described second anti-overflow module 8 includes resistance R 21, described resistance R 21 1 ends are connected with MCU controller 1 as the signal output part of the second anti-overflow module 8, resistance R 21 other ends are connected with resistance R 22 and capacitor C 21, described resistance R 22 other ends are connected with input voltage, capacitor C 21 other end ground connection also are connected with the second probe 81 that whether arrives sensed position for induction slurry foam on the tie point of described resistance R 21 and resistance R 22.
As shown in Figure 2, the detected slurry foam of the probe of described two anti-overflow modules has been equivalent to electric capacity two ends parallel connection equivalent resistance, anti-overflow module and the A/D conversion mouthful of level signal being exported to soy bean milk making machine MCU controller 1 consist of control loop by soy bean milk making machine MCU output interface and heater 3.Because the first anti-overflow module 7 is identical with the structure of the second anti-overflow module 8, realize that by MCU controller 1 program independent input triggers during design, so usually only need an anti-overflow module controls just can reach anti-overflow effect within the default short time, and the anti-overflow height of two anti-overflow modules can be arranged on sustained height, also can be arranged on different height and positions.
In the present embodiment, consider and to reach better heating purpose when anti-overflow, the appointment sensed position of the second anti-overflow module 8 second probes 81 is arranged on the appointment sensed position of the first probe 71 of the first anti-overflow module 7, with the triggering that realizes time successively with extend heat time heating time, reach better soy bean milk making machine slurrying control procedure.When soy bean milk making machine is anti-overflow, the first anti-overflow module 7 triggers when arriving the first anti-overflow module 7 probe location for rising when the slurry foam, then by time and the interval of the work of MCU controller 1 control heater 3 heating, namely reduce the heating dynamics, can just not overflow soon so after making it boiled; When the slurry foam rises to the second anti-overflow module 8 probe location, the second anti-overflow module 8 is triggered, at this moment need further anti-overflow control, the disconnection of MCU controller 1 control heater 3, prevent that effectively soy bean milk making machine generation slurries from overflowing, when slurry foam height descends, triggering signal is disappeared, soya-bean milk Production Time that MCU controller 1 is inputted according to internal processes and input key 4 judges whether that also needs continue heating.The utility model MCU controller 1 can also be after the first anti-overflow module 7 be triggered, the heating of carrying out the longer time interval when confiscating the triggering signal of the second anti-overflow module 8 within a period of time substituted with the cycle of suspending heating, quit work until surpass Preset Time.
Benefit of the present utility model can lose efficacy or detect when ineffective because of long-term the use at a probe exactly, it also can be by another anti-overflow probe in detecting to signal, can effectively control the excessive slurry situation of soy bean milk making machine, guarantee trouble free service, and setting and triggering due to two anti-overflow probe differing heights, the classification that has realized heater adds thermal control, reaches better heating effect.
