Slow start soaking device for beverage brewing machine

The present invention relates to a soaking device for a beverage brewing machine, which activates an electric control member to open the bottom water outlet of the beverage preparation container in a slow start manner when the preset soaking chamber is finished, and performs the water outlet.

The typical structure of the conventional beverage brewing machine is as shown in FIG. 8 , which mainly uses a water supply pump 80 to supply an external water source to a boiler 81. The boiler 81 is provided with a heater 82 and a temperature detector 83, thereby The water stored in the boiler 81 is heated to a set temperature range; when the beverage extraction process is performed, the user controls the hot water solenoid valve 84 to open, so that the hot water in the boiler 81 passes through a hot water outlet pipe 85 and A fixed sprinkler head 86 is sprinkled into a beverage preparation container 87 preset with ingredients, and the extracted beverage flows out from the bottom end outlet of the beverage preparation container 87 and is dropped into a storage tank 88 for storage.

Flow out. In the natural drip beverage preparation container 87, since the interaction time between the food material and the hot water in the beverage preparation container 87 is short, when a tea beverage such as black tea or green tea is prepared, a beverage having a long soaking time is required. The cooking effect is less than ideal.

Some conventional beverage brewing machines reduce the amount of water per unit time by reducing the diameter of the bottom outlet of the beverage preparation container, and prolong the time that the hot water stays in the beverage preparation container to obtain the food soaking effect; Species In the case of inaccurate control, it is often the case that, for example, the amount of water is too small to accumulate excess water in the beverage preparation container and overflows, or the amount of water is too large to obtain a desired soaking effect of the foodstuff.

A beverage preparation container for use in a commercially available electric coffee maker has been designed with a leak-proof gasket that utilizes an elastic member to maintain its bottom end outlet normally closed, but the function is to enclose the beverage preparation container from the electric coffee maker. The bottom outlet prevents the residual coffee liquid, the food material or the residue after the follicle in the beverage preparation container from polluting the environment; if the beverage preparation container with the normally closed leakproof gasket is placed in the electric coffee furnace, One of the struts or the like of the electric coffee maker opens the leak-proof gasket so that the bottom end outlet is opened, so that the coffee prepared in the beverage preparation container flows into a storage container in a natural dripping manner. Storage, therefore, a beverage preparation container having a normally closed leak-proof liner in a commercially available electric coffee oven is still a natural dripping beverage preparation method when extracting coffee, and is not suitable for preparing a long soaking time such as tea. Drink.
