Control system (400) hot water taking water-intake small pipe road (206) or the maximum of tap water water-intake small pipe road (208) unlatching number, that is,
Meet n1Number or n close to hot water water-intake small pipe road2Close to the number in tap water water-intake small pipe road, control system (400) is sent out
Going out signal makes control hot water miniature electromagnetic valve (207) open n1Individual, make control tap water miniature electromagnetic valve (209) open n2Individual；
Step 3, blending bin temperature sensor (203) records water temperature t of mixing water in blending bin3, hot water water-intake small pipe road (206)
Tap water actual flow velocity differing in middle hot water, tap water water-intake small pipe road (208), works as t3> t+3 DEG C or t3< when t-3 DEG C, real
Border situation is formula two
Wherein, n '1Number, n ' should be opened for hot water water-intake small pipe road (206)2Number should be opened for tap water water-intake small pipe road
Mesh, through calculating, obtaining hot water water-intake small pipe road (206), tap water water-intake small pipe road (208) should open control system (400)
The ratio n ' of the number opening1/n′2, control system (400) hot water taking water-intake small pipe road (206) or tap water water-intake small pipe road simultaneously
(208) maximum of number should be opened, that is, meet n '1Number or n ' close to hot water water-intake small pipe road2Enter close to tap water
The number of water small pipeline；
Step 4, control system (400) is by n '1With n1、n′2With n2Pass through formula three and formula four respectively
δ1=n '1-n1
δ2=n '2-n2
Carry out being calculated δ1With δ2, wherein, δ1With δ2All round numbers, work as δ1When 0, control system (400) controls opens
δ1Individual control hot water miniature electromagnetic valve (207), works as δ1< when 0, control system (400) controls closing-δ1Individual control hot water is miniature
Electromagnetic valve (207), works as δ2> 0 when, control system (400) control open δ2Individual control tap water miniature electromagnetic valve (209) works as δ2
< when 0, control system (400) controls closing-δ2Individual control tap water miniature electromagnetic valve (209), now blending bin water temperature reach t
±3℃；
Step 5, after user is finished water, blending bin temperature sensor (203) detects mixing water water temperature t in blending bin3, remaining
The temperature of water is cooled to predetermined temperature t ' control system (400) and passes through formula five
δ3=t3-t′
Carry out being calculated δ3, wherein, t3In the blending bin detecting for blending bin temperature sensor (203), mixing water is residual water
Water temperature, t ' is the recovery critical temperature of mixing water in blending bin set in advance, works as δ3When 0, control system (400) controls the
Three electromagnetic valves (211) are opened, and work as δ3< when 0, control system (400) controls the 3rd electromagnetic valve (211) to close.
