Description
One, technical field
The present invention relates to a kind of household electrical appliance, and relating in particular to one kind, there are two hot water barrels for installation in water dispenser, and
Pass through the water dispenser for the nothing big reserves timed power on/off of thousand boiling water that the single-chip microcontroller of master control borad automatically switches to heat up water.
Two, background technique
Common water dispenser, it is desirable that water all in machine should be drained from back drain valve weekly, and do primary cleaning, so
And the people done so almost without.Why have it is such require to be because of are as follows: water be cannot be by repeatedly boiled, here it is so-called
Thousand boiling water, thousand boiling water seriously affect people's health, and the water in hot water barrel boils repeatedly because that cannot drain completely, due to barreled
There is mineralogical composition in water, by prolonged heat temperature raising, it is surprising that heavy metal component and nitrite constantly accumulate content, therefore
Contain a large amount of carcinogen.Precipitating has many static water not circulated in drainage pipeline above drain valve, and water dispenser is long-term
Use, and long do not clear up if, a large amount of harmful substance of machine building up inside can breed a large amount of germs, such water dispenser
It is harmful to people's health.
Three, summary of the invention
The purpose of the present invention is to overcome the deficiencies of the prior art, and providing one kind, there are two hot water for installation in water dispenser
Bucket, and the water dispenser for the nothing big reserves timed power on/off of thousand boiling water for automatically switching to heat up water by the single-chip microcontroller of master control borad.
