process of draw runner 9 slide downward, tea basket 31 can be shifted onto the bottom of tee-steeping cup 3.When control circuit detects that lower contact 97 is touched, control circuit, except control is except motor 95 stops the rotation, controls tee-steeping cup simultaneously and enters water solenoid valve 8 and open, and allows the boiling water in water-boiling cup 2 flow in tee-steeping cup 3, when after the water yield reaching setting, control circuit control tee-steeping cup enters water solenoid valve 8 and closes.The tealeaves of tee-steeping cup 3 is soaked by boiling water.When reaching the soak time of setting, control circuit controls motor 95 again and reverses (turning clockwise), gear 96 on motor 95 output shaft drives the tooth bar 91 on draw runner 9, make draw runner 9 upward sliding, the tea basket magnet 311 that draw runner magnet 92 on draw runner 9 holds on tea basket 31 hauls tea basket 31 upward sliding, until after the upper contact head 97 on tooth bar 91 on draw runner 9 touches upper limit position switch 93, control circuit controls motor 95 and stops operating, at this moment, tea basket 31 is promoted, depart from tea, the concentration of such tea will be controlled preferably.At this moment, user can as required by " the tea delivery key " on control panel, controls tee-steeping cup and goes out water solenoid valve 10 and open, the teacup 6 on the tea tray 103 making tea fall on pedestal 4.Like this, whole EP (end of program) of making tea.If after the tea in tee-steeping cup 3 is all released, when control circuit to detect in tee-steeping cup 3 without tea, follow procedure is arranged the process of making tea restarting a new round by tea machine, just in this process, user does not need take out tee-steeping cup 3 and place tealeaves, and the control circuit on tea machine can be arranged and automatically carry out process of making tea, unless when tea machine reaches the number of times of the immersion of this tealeaves of setting by follow procedure, just need the tealeaves again more renewed, re-start setting operation.
