Water supply device for coffee extraction using vacuum force

Abstract

The present invention relates to a water supply device for extracting coffee using vacuum force. The water supply device for coffee extraction includes: a flow path connected to the water storage tank; a water supply container connected to the flow path, including a storage space and a water distribution component, the storage space can be used for water storage, and the water distribution component passes through multiple a water outlet hole to discharge the water stored in the storage space to the bottom; and a valve unit that adjusts the amount of water supplied to the water supply container by opening and closing the flow path, and forms an air passage communicating with the outside in the water supply container. The water supply device for extracting coffee further includes an air passage opening and closing device capable of opening and closing the air passage, and a vacuum force can be formed inside the water supply container by opening the valve unit to fill the water supply container with water. During this period, the air passage is opened, and after the water supply container is filled with a predetermined amount of water, the air passage is closed by the air passage opening and closing device. According to this structure, the present invention can provide the following water supply device for coffee extraction, that is, a vacuum force is formed inside the water supply container, thereby, the supply speed and amount of water supplied to the coffee powder can be adjusted, and the water supply to the coffee powder can be adjusted. The supplied water is uniformly distributed and supplied to a plurality of positions.

Description

technical field [0001] The present invention relates to a water supply device for extracting coffee using vacuum force. Background technique [0002] Generally, when coffee beans are used to extract coffee, according to the water temperature of the extracted coffee, it can be divided into drip coffee using warm water to extract coffee and cold drip coffee (cold brew coffee) using normal temperature water or cold water to extract coffee. [0003] Among them, the drip coffee is filled with warm water in a small coffee pot, and the user pours the warm water evenly into the coffee powder in the filter cup and extracts it in a short time of about 3 minutes. Ice drip coffee is coffee that is extracted by dropping normal-temperature water in a pitcher through a valve into a coffee basket containing coffee powder and taking about 3 to 20 hours. [0004] The taste of the drip coffee made by this process varies depending on the method and timing of supplying water to the coffee powde...

Problems solved by technology

However, the speed and amount of water supplied from the first container 10 and the second container 20 cannot be individually adjusted. Therefore, the water flows into the second container 20 too much to overflow to the upper part or with the amount of water in the second container 20. changes, the speed of the water falling through the second through hole will change due to the change of water pressure

[0010] In this case, the coffee extraction conditions cannot be maintained constantly, not only that, it is difficult for the user to make drip coffee with various flavors and tastes by adjusting the water supply speed and amount
