The circuit diagram of controller circuit board 35 of the present invention is described as follows below in conjunction with the principle of work of circuit diagram to controller circuit board 35 of the present invention as shown in Figure 8:
Mainly by one 8 Programmable Logic Controller U1 realization, Programmable Logic Controller U1 can select EM53/HT41 for use to the controllable function of controller circuit board 35.It has three kinds of mode of operations, is respectively constant voltage vacuum freshness retaining pattern, disinfection pattern and constant voltage vacuum freshness retaining+disinfection pattern.These three kinds of mode of operations are all realized by control button 39.
Enter the vacuum freshness retaining pattern once by control button 39 (K1), at this moment, indicator lamp (dual-colored LED) is shown in red, dodged every two seconds, air pump 32 begins to bleed, when the chamber pressure of box body 1 reaches the setting value of pressure difference switch 38, air pump 32 stopped to bleed after working 2 minutes again, the purpose that setting air pump 32 was worked 2 minutes again is that the negative pressure in the inner chamber of box body 1 is increased again, if gas leakage will wait a period of time after air pressure just can drop to setting value, having increased the work that air pump just can not be frequent under the gas leakage situation of this section phase buffer, mainly is to prolong the air pump life-span and save battery electric quantity.
When pressure difference switch 38 detected pressure in box body 1 inner chamber and the difference of pressure between the external atmosphere pressure less than setting value, pressure difference switch 38 sent control signal, and booster air pump 32 is bled once more, so repeatedly, keeps the pressure in box body 1 inner chamber.
When pressure difference switch 38 detected pressure reduction and is 0, air pump 32 time-delays started in 5 minutes, and this design mainly is when considering that the customer uses, uncover is got thing under the state of having forgotten shutdown, because the pressure in this moment box body 1 inner chamber is zero, therefore, air pump can start immediately, can cause waste like this.So start after having increased by 5 minutes, 5 minutes is the time of getting thing and lid lid to the customer.
If the air pump continuous working surpasses 9 minutes, pressure difference switch 38 does not still send the air pump stop control signal, and crisper gas leakage then is described, at this moment, control circuit board sends alerting signal, and the indicator lamp fast blink is shutdown automatically after 30 seconds.Test according to reality, if crisper is air tight, air pump 32 can be extracted into the pressure in box body 1 inner chamber preset value of pressure difference switch 38 fully in 9 minutes, so set this time, also do not have action to illustrate that then crisper has gas leakage if instead surpass 9 minutes baroswitches, at this moment just have the indicator lamp flicker and remind.
Under the vacuum freshness retaining pattern, click control button 39 (K1) again, to switch to the disinfection pattern, this moment, Programmable Logic Controller sent control signal, indicator lamp is shown in green and dodged every 2 seconds, ozone generator 33 work 10 minutes, stopped 5 minutes, and circulated in 15 seconds by working after 3 circulations every 2 hours.
Under the disinfection pattern, click control button 39 (K1) again and then enter constant voltage vacuum freshness retaining+disinfection pattern, this moment, indicator lamp was orange (red and green color mixes) and dodged every two seconds, under this pattern, ozone generator 33 was at first worked 10 minutes, stop clock after 10 minutes then, enter the vacuum freshness retaining circulation pattern afterwards, but indicator lamp still is orange.Then, ozone generator 33 is every work in 2 hours 15 seconds, but ozone starts as running into air pump when taking place, and then preferential air pump work waits air pump work to be over ozone takes place again, can avoid ozone to be taken away like this.
Under constant voltage vacuum freshness retaining+disinfection pattern, click control button 39 (K1) again and then enter constant voltage vacuum freshness retaining pattern, so repeatedly.
Under any mode of operation, the long control button 39 (K1) of pressing shut down after 2 seconds.
Whenever, as long as then orange lamp fast blink is reported to the police when voltage is lower than 4.5V, the machine auto-stop maybe can not restart when being lower than 4.1V.
This circuit enters low-power consumption energy saver mode (to prolong the period of service of internal cell) in standby after 2 seconds in addition, makes the stand-by power consumption of circuit be reduced to several microamperes.There is the button input to trigger MCU work up to circuit, makes circuit enter mode of operation.
