Description
Technical field
The utility model relates to the component of coffee machine, specifically is a kind of automatic valve in use for water supply apparatus of coffee maker.
Background technique
Tradition is too of a specified duration by the time of coffee powder because of water towards the boiler tool, thereby can't use careful coffee powder, so be difficult for obtaining best extraction ability.In order to accelerate to dash the time of making coffee, so that use thinner coffee powder, obtain best extraction ability, the Italian just in dashing the process of making coffee, utilizes piston (Piston) or pumping (Pump) that hot water is exerted pressure, hot water with these band pressure, on average push in the filter of filling coffee, so just can will be reduced in 30 seconds towards the time of boiling, even ten seconds, to quicken the process of extraction, obtain higher extraction ability.Thisly utilize high pressure and dash the mode of boiling fast,, just be called eSPResso, also this method is cooked the coffee that takes afterwards and be called eSPResso to obtain the practice of the highest extraction ability.This mode of boiling of dashing, not only can obtain very high extraction ability, aroma ingredients and colloid in all right agglomerated coffee, on coffee, produce the strong ember crema (Crema) of one deck, make that coffee is able to closely merge with strong milk froth, create the fancy coffee of various categories, improved the quality of coffee.Therefore and the fashionable whole world we can say that eSPResso has caused the revolution of coffee idea, and, become the main flow in coffee market.
The structure of the pressurized hot water supply system of pumping formula coffee machine is formed and working procedure is generally: have micro pump, one-way valve, water tank and boiler etc., the water intake of micro pump communicates with water tank, the outlet of micro pump connects the water inlet of one-way valve, unidirectional water outlet is communicated with boiler, also be provided with the return flow line between boiler and the water tank, the return flow line is provided with one-way valve structures.When the boiler internal pressure was not enough, micro pump started, and drew water from water tank and backed down one-way valve and inject boiler, after hydraulic pressure reaches setting pressure in the boiler, will open that the water outlet spring begins to infuse coffee in the boiler; Prescribe a time limit when hydraulic pressure in the boiler rises because of heating and surpasses on the setting value, then back down the one-way valve structures on the return flow line, reflow tank.Find in actual use, existing pumping pressurized water supply system comes with some shortcomings: the low only 2.5bar of pressure that 1, pumping formula coffee machine is adopted, high 19~the 20bar that reaches, and the retainable pressure ratio of the one-way valve structures of return flow line institute is more fixing in the existing pressurized water supply system, so the pressure water pump at different size need set different return flow lines, adaptability is wideless; 2, need be provided with refluxing opening and corresponding reflux line, structure more complicated separately on the boiler; 3, water pump may because of a period of time need not, reason generation sky such as water tank lacks water takes out, the air that causes not taking out in water, the pump housing is difficult to problems such as discharges, especially when depositing pressure in the boiler, possiblely especially damage water pump because of not taking out for a long time water.
