The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, (all leads omit among the figure) a kind of multifunctional microcomputer bathtub, comprise cylinder body 1, heating water tank 2, temperature sensor 3, level sensor 14, water pipe 4, water circulating pump 5, water inlet 6, delivery port 7, discharge outlet 8, wherein water circulating pump 5, heating water tank 2 link to each other with water inlet 6 and delivery port 7 by water pipe 4.Bathtub also comprises silicon nitride heater 9, wave generator 10, ozone generator 11, ozone pipeline 111, power pack 12 and control display board 13.
It is outer and near water circulating pump 5 that ozone generator 11 is arranged on described cylinder body 1, and control display board 13 and ozone generator 11 link to each other by lead.Ozone pipeline 111 1 ends connect ozone generator 11, and the other end connects water pipe 4.
As Fig. 4, control display board 13 upper surfaces comprise temperature, time, ozone, four indicator lamps of power supply, power supply, add, subtract, setting, five buttons of wave and the charactron 133 that is used for information such as demonstration time, temperature, literal is printed on control display board 13 upper surfaces among the figure.
The multifunctional microcomputer bathtub control method may further comprise the steps:
The energising of a bathtub, power supply indicator is lighted.This moment, all the other indicator lamps all extinguished, and can start shooting by power button, and all the other buttons all do not have response.Any time can shut down by power button after the start.Press the power button start, this moment design temperature and shower time are acquiescence (set water temperature of acquiescence is 35 ℃, and the shower time is 30 minutes), and charactron 133 shows real-time water temperature.If water temperature is lower than acquiescence water temperature certain numerical value (for example 2 ℃) in real time, the single-chip microcomputer 131 of control display board 13 transmits signal and gives silicon nitride heater 9 and water circulating pump 5, and silicon nitride heater 9 and water circulating pump 5 start.Treat that real-time water temperature surpasses acquiescence water temperature certain numerical value (for example 2 ℃), the single-chip microcomputer 131 of control display board 13 transmits signal and gives silicon nitride heater 9 and water circulating pump 5, and both stop.
By the button that adds deduct, signal sends charactron 133 to from the single-chip microcomputer 131 of control display board 13 under the b open state, and charactron 133 demonstrations are provided with water temperature.In default time (for example 3 seconds), the button that adds deduct no longer provides signal, and single-chip microcomputer 131 memories of then controlling display board 13 are provided with water temperature.But the water temperature setting range is 20 ℃～45 ℃.
If real-time water temperature is lower than water temperature certain numerical value (for example 2 ℃) is set, the single-chip microcomputer 131 of control display board 13 transmits signal and gives silicon nitride heater 9 and water circulating pump 5, silicon nitride heater 9 and water circulating pump 5 start, treat that real-time water temperature surpasses acquiescence water temperature certain numerical value (for example 2 ℃), the single-chip microcomputer 131 of control display board 13 transmits signal and gives silicon nitride heater 9 and water circulating pump 5, and silicon nitride heater 9 and water circulating pump 5 stop;
Under the c open state, press button is set, the single-chip microcomputer 131 of control display board 13 provides signal, and the time indicator lamp of making is lighted.Can set shower time (for example take a shower time set scope be 20 minute～90 minute) by the button that adds deduct this moment, whenever by button time lengthening or the shortening certain numerical value (for example 10 minutes) of once adding deduct.The single-chip microcomputer 131 of control display board 13 sends a signal to charactron 133, and charactron 133 shows the time that is provided with.In default time (for example 3 seconds), the button that adds deduct no longer provides signal, and then single-chip microcomputer 131 memories are provided with the time.
Under the d open state, random time is pressed the wave button, and signal transmits signal from the single-chip microcomputer 131 of control display board 13, starts wave generator 10, presses the wave button once more, and then wave generator 10 stops.
When e is less than certain hour (for example 5 minutes) when the residue shower time, the single-chip microcomputer 131 of control display board 13 drives ozone 11 generators and starts working, ozone generator power 0.9W, and the ozone indicator lamp on the control display board 13 is lighted, and single-chip microcomputer 131 control buzzers 132 sounding once simultaneously.
The ozone of low concentration has health care, sterilization, and the cuticular function of gentle removal skin aging, but excessive ozone is then harmful, and therefore, the ozone time should be shorter, and power should be lower.
When f became 0 when the residue shower time, 131 control time of single-chip microcomputer indicator lamp was lighted, and charactron 133 shows " 0 "; The control display board 13 prompting several seconds (for example 3 seconds) of 13 control buzzings, buzzing finishes back shutdown automatically.
Random time in the above-mentioned steps, when control display board 13 detects real-time water temperature and is higher than certain numerical value (for example 48 ℃) or water level when being lower than level sensor, single-chip microcomputer 131 all quits work water circulating pump 5, wave generator 10, silicon nitride heater 9, ozone generator 11, charactron 133 shows actual water temperature and flicker, and buzzer 132 is reported to the police, and all buttons stop response except that power button.After being lower than set water temperature or water level to be higher than designated water level, water temperature recovers automatically.
Random time in the above-mentioned steps, when the single-chip microcomputer 131 of control display board 13 detects temperature sensor 3 faults, control display board 13 all quits work water circulating pump 5, wave generator 10, silicon nitride heater 9, ozone generator 11, error coded (as E1) that charactron 133 display settings are good and flicker, temperature, time, ozone indicator lamp all extinguish, buzzer 151 is reported to the police, and all buttons stop response except that power button.When the recovery automatically of the normal back of temperature sensor 3.
