Description

[Technical Field]

[0001] The present invention relates to a beverage extraction method for extracting beverage components from dry beverage ingredients, and in particular to an extraction method in which the degree of extraction is adjusted by adjusting the separation time between the ingredients and the extract, based on the positional relationship between a hot water storage container that reduces the weight of the beverage ingredients by discharging hot water to separate them from the drinking liquid after extraction and a weight installed opposite a fulcrum. [Background technology]

[0002] For example, teas such as green tea and black tea are made drinkable by steeping the beverage ingredients in hot water in a teapot or server for a set period of time, and then draining the liquid from the container into a teacup or cup while monitoring the degree of extraction. Coffee, meanwhile, has two extraction methods: the permeation method, in which hot water is passed through ground coffee beans and the liquid is then dropped into a server at the bottom, and the immersion method, in which coffee powder is steeped in the extract like tea and then the extract is separated from the coffee powder. The extraction method and steeping time are adjusted depending on the ingredients and the drinker's preferences.

[0003] However, when extracting tea or coffee using the immersion method, if the extraction timing is exceeded, the coffee will be extracted stronger than necessary and many impurities will be extracted, making it impossible to leave the place.Furthermore, with the permeation method, as typified by hand drip coffee, it is necessary to continuously pour hot water over the coffee beans, which is extremely time-consuming.

[0004] Of course, to compensate for these drawbacks, many electric coffee makers and tea brewing devices are available. Particularly advanced devices have been proposed that memorize the brewing method for each tea leaf or coffee ingredient and allow the appropriate brewing at the touch of a button.

[0005] However, this type of product requires handling of a power cord and cannot be used in environments without a power source, so there was a need for a method of adjusting the extraction level using a device that does not require a power source such as a power source. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2017-131642 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made in recognition of this background, and attempts have been made to develop an extraction device that does not use a power source and allows adjustment of the extraction degree. [Means for solving the problem]

[0008] In other words, the method for adjusting the degree of beverage extraction described in claim 1 is a beverage extraction device comprising a hot water storage container of appropriate capacity, a filter that receives hot water from the hot water storage container, holds the beverage ingredients contained therein, and extracts the beverage components, and a lever rod that lifts the hot water storage container and filter from the server by the action of a weight facing the fulcrum due to the weight reduction caused by the hot water being discharged from the hot water storage container, wherein at least a part of the lever rod is provided with a moment adjustment function that adjusts the distance from the fulcrum, and the degree of extraction of the drinking liquid is adjusted by increasing or decreasing the time it takes to lift the beverage ingredients from the drinking liquid by adjusting the distance from the fulcrum.

[0009] Furthermore, the beverage extraction degree adjusting mechanism described in claim 2 is characterized in that, in addition to the requirements of claim 1, it is made up of a lever rod extension / retraction mechanism attached to the lever rod.

[0010] Furthermore, the beverage extraction degree adjusting method described in claim 3 is characterized in that, in addition to the requirements described in claim 1 or 2, the moment adjustment function is achieved by moving the position of a weight mounting part attached to a lever rod.

[0011] Furthermore, the beverage extraction degree adjusting method described in claim 4 is characterized in that, in addition to the requirements described in any one of claims 1 to 3, the moment adjustment function is achieved by adjusting the angle of at least one point of the lever rod.

[0012] The tea extraction device according to claim 5 is characterized in that the degree of beverage extraction is adjusted by any of the methods according to claims 1 to 4. [Effects of the Invention]

[0013] The above-mentioned problems are solved by the configuration of the inventions described in each of these claims. First, according to the invention described in claim 1, the lever bar is provided with a moment adjustment function that adjusts the distance from the fulcrum at least in part, and the degree of extraction of the drinking liquid is adjusted by adjusting the time for pulling the beverage ingredients out of the drinking liquid through this distance adjustment. Therefore, the infusion time of the beverage ingredients is adjusted by adjusting the distance from the fulcrum, i.e., the moment, without changing the weight of the weight, and therefore the infusion time can be quickly changed without the need for troublesome replacement or adjustment of the weight.

[0014] Furthermore, according to the invention described in claim 2, the moment can be adjusted to the appropriate moment in a very short time because the moment is changed by adjusting the extension and contraction of the lever rod.

[0015] Furthermore, according to the invention described in claim 3, the moment adjustment function is achieved by moving the position of the weight mounting part attached to the lever bar, so the mechanism can be constructed at very low cost.

[0016] According to the invention of claim 4, the moment adjustment function is achieved by adjusting the angle of at least one point of the lever bar, so that moment adjustment can be achieved with a simple structure.

[0017] Furthermore, according to the invention described in claim 5, the beverage brewing device can vary the degree of extraction by adjusting the moment, so it can be used with many types of beverage ingredients. [Brief explanation of the drawings]

[0018] [Figure 1] This is an explanatory diagram of an apparatus equipped with a weight hanging hook for coffee and tea that can hang weights at different moments, and a screw mechanism for fine-tuning the moment of each hanging hook, as an embodiment of the present invention. [Figure 2] FIG. 2 is an enlarged view of the screw mechanism for moment adjustment with multiple hanging hooks of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention is embodied in the following examples, and also includes various methods that can be improved within the scope of the present invention. [Example]

[0020] As shown in the overall view of Figure 1, for example, the tea extraction device is structured so that when hot water for extraction is poured into hot water storage container 21, the weight of the hot water lifts weight 16, which is attached to a lever rod via a fulcrum, and a filter containing beverage ingredients held in filter installation net 22 is dropped into a server (not shown). The poured hot water passes through hot water injection pipe 25 and falls into the filter containing the ingredients, where beverage components are extracted from the beverage ingredients inside the server.

[0021] As the hot water is discharged from the hot water storage container 21, the weight of the weight portion 16 gradually moves downward, lifting the beverage ingredients together with the filter from the server, and eventually lifting them completely above the surface of the drinking liquid in the server, thereby completing the extraction of the beverage.

[0022] The above is the method for lifting the brewing material from the server using this brewing device, but the timing of lifting varies depending on the moment caused by the weight of the weight and the distance from the fulcrum. As shown in the enlarged view of Figure 2, in this embodiment of the present invention, a nut equipped with a hook for hanging the weight is set on multiple moment fine adjustment screws 12, and large differences in the timing of lifting depending on the type of beverage, such as coffee or tea, are made by moving the position of the weight hook, while fine adjustments based on the type of beverage and preference are made by small adjustments to the moment by rotating the nut.

[0023] Tea strainers and coffee filters have different rates at which hot water passes through, with tea strainers generally having a faster rate of hot water permeation, and since the weight needs to be lighter and the time it spends in the hot water needs to be longer to ensure the tea leaves have time to open up in the hot water, the moment is made lighter than when extracting coffee by hanging the weight from weight hanging fixture 13, which is closer to the fulcrum. Also, fine adjustments to the time required to accommodate differences in the degree of steaming of green tea can be made by rotating the nut on weight hanging fixture 13 and adjusting the moment using the screw mechanism, allowing for major changes between tea and coffee to be made in a short time by simply changing the hanging hook, while also allowing for more delicate fine adjustments.
