Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of a coffee brewing method of the present invention, which can be applied to a coffee brewing apparatus or other beverage making apparatus (hereinafter, referred to as apparatus collectively). As shown in fig. 1, in the present embodiment, the coffee brewing method includes the following steps:

and S1, receiving the taste requirement information.

Specifically, the user inputs mouthfeel requirement information through an input area on the device, wherein the mouthfeel requirement information is mouthfeel information which comprises one or more different attributes and can be selected by the user, and the mouthfeel information comprises one or more of, but is not limited to, coffee thickness information, sweetness thickness information and temperature information. The taste information of each attribute comprises one or more different degrees of taste, for example, the degree of taste of the gradation information comprises strong, standard and light, the degree of taste of the sweetness information comprises sweet, standard and less sweet, and the degree of taste of the temperature information comprises hot, warm and normal temperature.

The input area on the device at least comprises a selection item and an activation item, one selection item can correspond to the taste information of one attribute, each selection item comprises a plurality of different degrees of taste degrees for selection, for example, a user can select the strong taste degree in the selection item of the gradation information, and the input taste demand information is strong. For the convenience of the user, if the number of the current selection items is greater than 1, when the user does not finish the selection of all the selection items, namely, the coffee brewing program is started, the default mouthfeel degree corresponding to the selection item which is not finished and selected by the user is used as the mouthfeel degree input of the item.

It is understood that the default level is obtained by market analysis, and is a level that is more suitable for the taste of the general public. In the present embodiment, the default taste degree is set as the intermediate degree item in each selection item, for example, the default taste degree in the gradation information is the standard, the default taste degree in the sweetness information is the standard, and the default taste degree in the temperature information is the temperature. For example, the user inputs a strong taste degree through the gradation selection item to start the brewing process, that is, the taste of the finally brewed coffee is the coffee with strong gradation information, standard sweetness information and warm temperature information.

When the coffee brewing program is started, the device reads the taste degree corresponding to one or more attributes finally input by the user, and takes the input information as the taste requirement information.

And S2, reading the liquid ion concentration value of the coffee to be brewed, and identifying the type of the coffee to be brewed according to the liquid ion concentration value.

It will be appreciated that each type of coffee has its own characteristics, and therefore the different types of coffee will have different brewing solutions to be configured for the same taste level of the same attribute, and therefore it is necessary to identify the type of coffee currently to be brewed.

Specifically, after a coffee brewing program is started, the equipment system controls a small amount of water to be mixed with a small amount of coffee powder to be brewed to obtain a mixed liquid, detects a liquid ion concentration value of the mixed liquid through the ion concentration detection unit, and identifies the type of coffee to be brewed according to the obtained liquid ion concentration value. It will be appreciated that the small amount of water and the small amount of ground coffee can be controlled by the system weighing, and the resulting amount of mixed liquor is only sufficient for identifying the type of coffee, which can subsequently be mixed into the final brewed coffee; in some embodiments, the mixture may be discharged as a waste liquid, which, in any event, has a negligible effect on the mouthfeel of the final brewed coffee.

As shown in fig. 2, the ion concentration detection unit includes a probe, an RC oscillation circuit, and an inverter. In the detection process, the control probe is inserted into the mixed liquid, the total concentration of liquid ions of the coffee liquid of the coffee to be brewed is detected and obtained, and the total concentration is fed back to the RC oscillating circuit to form RC oscillation so as to obtain an oscillating signal, the oscillating signal is combined with the phase inverter to convert the oscillating signal into a pulse signal, and a detection signal value is generated according to the pulse signal. The device system can preset the corresponding relation between the liquid ion concentration value and the detection signal value, when the detection signal value is obtained through the ion concentration detection unit, the corresponding liquid ion concentration value can be obtained through the preset corresponding relation, and finally the type of the coffee to be brewed can be obtained through the corresponding relation between the liquid ion concentration value and the type of the coffee to be brewed.

And S3, determining a brewing scheme corresponding to the mouthfeel requirement information based on the type of the coffee to be brewed.

It can be understood that after the type of the coffee to be brewed is determined, the brewing scheme can be determined according to the preset corresponding relation between the taste requirement information and the brewing scheme, and the coffee with the taste consistent with the taste requirement can be obtained by brewing according to the brewing scheme.

Wherein, the scheme corresponding to each taste degree in each attribute is different, wherein the scheme can be the mass ratio among materials, for example, different taste degrees of the gradation information correspond to different mass ratios of coffee powder/coffee beans and water, and different taste degrees of the sweetness information correspond to different mass portions of flavoring agents, wherein, the flavoring agents comprise one or more of sugar, salt, milk and honey. The brewing scheme can be brewing temperature, and different mouthfeel degrees of temperature information correspond to different brewing temperatures.

It can be understood that the mixed liquid in the step S2 is obtained by weighing the water and the coffee powder in rated mass portions, and the coffee powder and the water in the brewing scheme have the mixed liquid portion removed, so that the error of the taste of the brewed coffee is effectively reduced; in the embodiment in which the mixed liquid in step S2 is discharged as the waste liquid, the coffee powder and the water in the brewing scheme have the original whole portions, so that the taste of the brewed coffee is not affected even if the mixed liquid is discharged as the waste liquid.

As can be appreciated, after the brewing protocol corresponding to the mouthfeel requirement information is determined, brewing of coffee is performed according to the brewing protocol. The coffee powder/coffee beans and water in corresponding mass ratio and the flavoring agent in corresponding mass parts are prepared in a weighing mode, coffee is mixed and brewed, the brewing temperature of the coffee is controlled in a temperature control mode, and finally the coffee with the taste consistent with the taste requirement information of a user is obtained.

In an embodiment that the mixed liquid is mixed into the finally brewed coffee or the mixed liquid is discharged as waste liquid, the equipment system is weighed according to the mass share of the brewing scheme, the total mass share of the obtained coffee powder/coffee beans and water is equal to the original complete share of the brewing scheme corresponding to the taste requirement, and the coffee with the taste consistent with the taste requirement information of the user is obtained.

The present invention provides a second embodiment of a coffee brewing method, comprising the steps of:

and S1, receiving the taste requirement information.

The present embodiment is different from the first embodiment described above in that, in the present embodiment, before step S1, the method further includes:

s0-1, establishing the corresponding relation between each coffee type and the liquid ion concentration value in advance.

It will be appreciated that each type of coffee has its own characteristics, and that different types of coffee differ in the brewing protocol to be configured to the same extent for the same attribute, and therefore the type of coffee needs to be determined before reading the brewing protocol.

Each coffee type has a corresponding liquid ion concentration value, so that the coffee type can be identified through the liquid ion concentration value. Taking n kinds of coffee which can be identified by the device as an example, n is greater than 1, the corresponding relation between the n kinds of coffee and the liquid ion concentration value is established, as shown in the following table I.

Table one:

kind of coffee	1	2	…	n
					Liquid ion concentration value (mol/L)	a	b	…	m

Wherein, for the sake of distinction, assume a-m are liquid ion concentration values corresponding to 1-n coffee species, respectively, a-m may represent the same or different values, and the actual values can be obtained from the data of the prior art.

S0-2, establishing the corresponding relation between the taste requirement information of each coffee type and the brewing scheme in advance.

It can be understood that, for different coffee types, the brewing schemes configured at the same degree of the same attribute are different, for example, for coffee type 1, a strong taste degree can be achieved when a large amount of coffee powder is added, and for coffee type 2, a strong taste degree can be achieved when a small amount of coffee powder is added, so that the brewing schemes corresponding to the taste strengths of the attributes of the coffee type need to be established according to the characteristics of each coffee type. In the following, taking the coffee type 1 as an example, a scheme corresponding to the degree of taste such as intensity, standard, lightness, etc. of the gradation information is established, as shown in table two.

Table two:

wherein the brewing scheme is the mass parts of the added coffee powder/coffee beans and water and the mass ratio thereof, and understandably A is more than B and more than C. It is understood that the coffee powder/coffee bean and water mass parts and the mass ratio thereof in table two represent the parts of the mixed liquid portion that has been removed; in the example in which the mixed liquor was discharged as waste liquor, the coffee powder/coffee bean and water mass parts and the mass ratio thereof in table two represent the original whole portions.

A scheme corresponding to the degree of the tastes such as partial sweetness, standard sweetness and little sweetness of the sweetness intensity information is established, as shown in table 3.

Table three:

wherein the brewing scheme is the mass parts of the added flavoring agent, the flavoring agent can comprise one or more of sugar, salt, milk and honey, and D is more than E and more than F.

It will be appreciated that the brewing temperature required to achieve the same degree of flavour of the same attribute will also be different for different coffee varieties, for example coffee variety 1 will have a lower temperature at the hot mouthfeel level than coffee variety 2 to retain its characteristic properties. In the following, taking coffee type 1 as an example, a recipe corresponding to the taste levels of heat, temperature, room temperature, etc. of the temperature information is established, as shown in table four.

Table four:

wherein the brewing scheme is the coffee brewing temperature, and G is more than H and more than I understandably.

The following describes the flow of the coffee brewing method in the second embodiment when the taste requirement information is input by the selection command. As shown in fig. 3, the coffee brewing method comprises the following steps:

s100, establishing a corresponding relation between each coffee type and the liquid ion concentration value in advance.

S102, taste requirement information that the gradation information input through the selection instruction is light, the sweetness information is less sweet and the temperature information is normal temperature is received.

It is to be understood that the user selects a light mouthfeel degree through the gradation information selection item, a less sweet mouthfeel degree through the sweet gradation information selection item, and a normal temperature mouthfeel degree through the temperature information selection item. After the coffee brewing program is started by the user, the equipment reads in the taste degree information corresponding to all the items as a selection instruction and confirms the taste degree information as taste requirement information.

S103, reading the ion concentration value a of the liquid of the coffee to be brewed, and identifying the type of the coffee to be brewed as 1.

It can be understood that, when the ion concentration detecting unit reads that the liquid ion concentration value is a, the coffee to be brewed is identified as coffee type 1 according to the corresponding relationship between each coffee type and the liquid ion concentration value, that is, according to the corresponding relationship in table one.

S104, based on the type of coffee to be brewed being 1, determining the brewing scheme to be coffee powder/coffee beans (g): water (g) ═ C: 1. flavor (g) ═ F, temperature ═ I.

It can be understood that, according to tables two, three and four, respectively, the scheme corresponding to the light taste degree in the coffee category 1 can be determined as the mass ratio of coffee powder/coffee beans (g): water (g) ═ C: the specified mass parts of the coffee powder and the water in the 1, the scheme corresponding to the degree of the less sweet taste is that the mass part of the flavoring agent is F, and the scheme corresponding to the degree of the temperature taste is that the temperature is controlled to be I.

And S105, brewing according to the brewing scheme to obtain the coffee with light, little sweet and normal temperature mouthfeel.

It is understood that the mass ratio of coffee powder/coffee beans (g) is configured by weighing: water (g) ═ C: 1, preparing F parts of flavoring agent by mass of coffee powder and water, mixing and brewing the materials, and controlling the brewing temperature of the coffee to be I, thus obtaining the normal-temperature coffee with light and less sweet taste by brewing.

S202, taste requirement information with the concentration information as standard, the sweetness information as standard and the temperature information as temperature input in a default mode is received.

It can be understood that the user does not input the taste requirement information of each attribute through the selection item, and when the coffee brewing program is directly started, the default taste degree in each attribute is automatically input into the equipment system, namely, the taste requirement information received by the equipment system is the standard of the gradation degree information, the standard of the sweetness degree information and the temperature information.

S203, reading the ion concentration value of the liquid of the coffee to be brewed as a, and identifying the type of the coffee to be brewed as 1.

S204, based on the type of coffee to be brewed being 1, determining the brewing scheme to be coffee powder/coffee beans (g): water (g) ═ B: 1. flavor (g) ═ E, temperature ═ H.

S205, brewing according to the brewing scheme to obtain the warm coffee with the taste of concentration and the sweetness standard.
