Drain valve 4 processed:
Condition one: drain valve 4 is currently in off state；
Condition two: total accumulative dwell time of steam generation part 3 is at least the first setting time T1；
Condition three: the current closed state of steam generation part 3 at least continues the second setting time T2.
That is, humidifier 100 when detecting that above three condition is all satisfied, can just consider to open drain valve 4.
And in actual products, according to actual needs, other additional conditions may be arranged in humidifier 100, to above three condition
And additional other conditions are all satisfied, and just open drain valve 4, are no longer limited other additional conditions here.Define " the
One ", the feature of " second " can explicitly or implicitly include one or more of the features.
Wherein, condition one refers to, drain valve 4 is currently at closed state, and drain valve 4 can just be cut after other conditions satisfaction
Change opening state into.
Condition two refers to that steam generation part 3 is in the sum of time cumulation of halted state and is at least the first setting time T1,
Drain valve 4 can just switch to opening state after other conditions satisfaction.Here total accumulative dwell time, is by steam generation part
3 time not under operation made the accumulative adduction calculated time.
Condition three refers to that steam generation part 3 is currently in off state, and the shut-in time at least continues the second setting time
T2, drain valve 4 can just switch to opening state after other conditions satisfaction.
Timer 5, can be primary in the every closing of steam generation part 3 in the total accumulative dwell time for counting steam generation part 3
Meter is primary, and then each dwell time of steam generation part 3 is transferred in the controller 8 of humidifier 100, will be counted by controller 8
All dwell times adduction of Shi Qidian so far, timer 5 is reset after each steam generation part 3 is opened.Alternatively, timer 5 from
Time zero starts timing, and timer 5 suspends after each steam generation part 3 is opened, should after steam generation part 3 is closed next time
Timer 5 continues timing, until the timer 5 is reset when drain valve 4 is opened.
Here the setting of condition two shows in Work container 2 to have added up the enough time since timing point
It is idle, and as standby time is longer, the bacterium bred in water is more, it is therefore desirable to the dirt of discharge bacterium containing high concentration in time
Water.It is to be understood that steam generation part 3 can be to bacterium to water acting when steam generation part 3 is in the open state
It breeds and generates certain inhibiting effect, such as affect the growth temperature of bacterium when steam generation part 3 heats, when steam generation part
Bacterium is possibly even killed when 3 sending ultrasonic waves or infrared ray.Therefore for condition two in setting, record is steam generation part
3 are in the sum of the time cumulation of halted state.
And the setting of condition three, show that part 3, which occurs, in current steam has had considerable time to be not turned on, i.e. steam
Part 3 occurs and is in idle state, this condition opens drain valve 4 after meeting again, can avoid the normal humidification of draining influence and needs.
Here why without controlling forced drainage using Concentration Testing part, i.e., when Concentration Testing part detects in water carefully
It is drained again when bacterial content is exceeded, is the other Concentration Testing the part after long-term use because detection accuracy of Concentration Testing part is not high
The dirty layer on surface will affect detection accuracy, and drain valve 4 is caused to switch frequently.And the scheme of the embodiment of the present invention, control logic is more
Adduction reason, avoids drain valve 4 from frequently switching on draining, to avoid the influence to 100 normal function of humidifier.

Humidifier 100 controls the opening of drain valve 4 and also needs to meet condition: current water is less than setting water in Work container 2, that is, work appearance
The spilling water flag bit of device 2 is OFF.It is can avoid in Work container 2 in this way plus dilutional hyponatremia leads to spilling water situation occur.
Specifically, drain valve 4 is closed after opening up to third setting time T3.Here setting water discharge time is set up to third
Time T3 guarantees that water discharge time is sufficient, utilizes emptying sewage.In addition, just being closed after drain valve 4 opens third setting time T3
It closes, rather than opens preceding closing in steam generation part 3 next time, be to be able to enough time moisturizing, waited steam when needing
Part 3, which occurs, can be immediately heated gas processed.
In certain embodiments, a Work container 2 is correspondingly provided with multiple steam generation parts 3, in detection drain valve 4
When meeting opening condition, timer 5 is in the time of closed state in all steam generation parts 3, when being included in total accumulative stopping
Between in.Such as steam generation part 3 there are four being set in Work container 2, only when four steam generation parts 3 are in halted state
When, this section of dwell time can be just included in always accumulative dwell time.
In certain embodiments, a Work container 2 is correspondingly provided with multiple steam generation parts 3, in detection drain valve 4
When meeting opening condition, the closed state for needing each steam generation part 3 current at least continues the second setting time T2；Its
In, the corresponding second setting time T2 of multiple steam generation parts 3 is equal or different.It can guarantee that a Work container 2 exists in this way
When draining, corresponding all steam generation parts 3 avoid result in dry combustion method phenomenon all in closed state.
