A kind of coffee machine with automatic cleaning function
The utility model belongs to household appliance technical field more particularly to a kind of coffee machine with automatic cleaning function.
Leak through type coffee machine on existing market is since nineteen sixty-five utility model, due to its principle and product structure letter
It is single, it is at low cost, liked by consumers in general always, structure adopts always so far.But since such product uses coffee
Powder, and ground coffee is not easy to retain is easy to make moist etc. and influences mouthfeel and fragrance, so the raw material that existing market supplies essentially toasts
Good coffee bean is used so needing coffee bean is separately ground into ground coffee with grinding machine before making coffee, increases and make coffee again
Action, and be inconvenient to operate.
Based on some existing problems above, also occur some currently on the market by ground coffee beans and function of making coffee
The machine to integrally combine, principle are essentially crushing chamber and carry filter screen, and a kind of mode is after coffee bean is crushed to certain fineness
Under the action of the centrifugal force by entering coffee extracted chamber after the filter screen on crushing chamber, after heating tube work, by siphonic effect,
Water flows into coffee extracted chamber after being heated, and carries out coffee making.This mode is since coffee extracted chamber is connected to crushing chamber, and powder
Broken chamber also has certain ground coffee residual, and crushing chamber needs to clean and water vapour can enter crushing chamber and condense.Cleaning objects
More and usage experience is bad.Another way is coffee bean crushing chamber and coffee extracted chamber one, coffee bean crushed after in powder
Broken intracavitary is extracted, crushing chamber and filter screen, and lid all needs to be cleaned, and cleaning component is more, and crushing chamber is easy to forget after making
