Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a drip-type coffee extractor.

(Prior Art) In recent years, as people's eating habits have improved, there has been a growing trend for people to buy coarsely ground coffee and enjoy making straight coffee at home, and drip-type coffee brewers have become widely commercialized.

However, in conventional drip-type coffee brewers, the hot water spout installed at the bottom of the hot water tank and the brewing tip with the dripper below it are both fixed in position, so the hot water from the upper hot water tank flows through the coarse grind inside the dripper. Since the coffee cannot be poured evenly and evenly over a wide range of coffee grains, it is not possible to achieve a completely proper coffee extraction. In addition, in the conventional method, the steaming of coffee grains, the extraction time, and the amount of extraction cannot be adjusted to the desired state, making it difficult to obtain the desired taste.

(Technical Issues) Therefore, this invention makes it possible to freely adjust the steaming time of coffee grains and the coffee extraction time to the appropriate and desired state, and also allows hot water to be uniformly injected into coarsely ground coffee grains over a wide area. This allows for complete coffee extraction.

(Technical Means) This invention was made in order to solve the above-mentioned technical problem, and the drip-type coffee extractor of this invention will be described in detail below with reference to the drawings. provided lid 3
The lower end of the hot water tank 2 is a down-flow pipe 4 in which a control valve 7 operated by a handle 8 is interposed, and the lower end thereof is connected to an inverted T-shape with a large number of valves arranged in different positions on both the left and right sides. A horizontal straight pipe-shaped ejector 5 having an ejection hole 6 is provided. In addition, the above-mentioned ejector 5
It is desirable that the number of the ejection holes 6 is as large as possible, and it is also desirable that the ejection holes 6 on both the left and right sides are arranged at opposite positions, respectively, as in the embodiment shown in the drawings. Reference numeral 11 denotes a rotating disk that can rotate slightly above the lower portion 1b of the main body 1, and the rotating disk 11 is fixed horizontally to the upper end of the shaft 10 of the deceleration motor 9. Reference numeral 12 denotes a cap-shaped mounting plate having locking claws 13 protruding from several locations on the outer periphery of its upper surface, and is removably mounted on the rotary disk 11. Further, reference numeral 14 denotes a extraction tip placed on the above-mentioned plate 12, and each locking pawl 13 prevents the movement of the extraction tip during rotation. Reference numeral 15 denotes a dripper that is removably fitted into the upper opening of the extraction tip 14, and has an outflow hole 15a at the center of the bottom. and the dripper 1
As shown in FIG. 1, a stainless steel filter mesh basket 16 and a filter paper bag 17 are fitted into the inner surface of the container 5, respectively, and an appropriate amount of coarsely ground coffee grains 18 are housed inside.

The product generally uses a beaker with a graduated measurer as the extraction tip 14.

(Operation) In the state shown in the drawing, first, the control valve 7 is opened to an appropriate opening degree, the switch is turned on, and the extraction cup 14 on which the dripper 15 is mounted is placed at a low speed position by the deceleration motor 9. Next, hot water that has been previously boiled in a separate device such as a kettle is poured into the hot water tank 2. Then, the hot water is sequentially dripped from each spout hole 6 of the spout 5 onto the coarsely ground coffee grains 18 in the dripper 15 rotating at a low speed, impregnating it, and flowing through the outflow hole 15a into the brewing spout below. Extracted coffee is sequentially extracted and accumulated in the chamber 14.

(Effects of the invention) As mentioned above, the coffee extractor of this invention has the following features:
Since the jetter 5 is provided with a regulating valve 7 interposed at the lower end of the hot water tank 2, by controlling the amount of hot water supplied by operating the regulating valve 7, the degree of steaming of coffee grains, coffee extraction time, extraction amount, etc. can be adjusted as desired. It has outstanding effects and can be performed freely and appropriately depending on the situation. Also squirt device 5
Since the lower dripper 15 can rotate the extraction tip 14 which is removably mounted,
By rotating the dripper 15 containing the coffee grains, the hot water from each spout hole 6 of the jetter 5 can be evenly poured over a wide area and impregnated the coarsely ground coffee grains 18, resulting in perfect quality coffee. It has an excellent effect of stably extracting coffee. Furthermore, since the ejector 5 is in the form of a horizontal straight tube having a large number of ejection holes 6 arranged at opposite positions on both the left and right sides on the lower surface, there is an effect that hot water can be ejected from each ejection hole 6 evenly and effectively and evenly. Further, by rotating the brewing tip 14, the brewed coffee inside is stirred, which has the effect of making it possible to obtain a more uniform quality coffee.
