Background

Coffee is a very popular beverage, at present, coffee can be divided into instant coffee and freshly ground coffee, the instant coffee is powder obtained by extracting active ingredients from coffee beans and then drying, part of aroma can be lost in the preparation process, on the premise of the same quality of coffee beans, the instant coffee is rich and pure like freshly ground coffee, the freshly ground coffee is brewed on site, the aroma of the coffee is more rich, and the mouthfeel is better, so that freshly ground coffee is popular in the market.

Freshly ground coffee is usually produced by a coffee machine, which usually uses a water pump to pump water to a boiler during the production of coffee, the boiler heats the water and then impacts the coffee powder under the pressure of the water pump, thereby obtaining an extracted coffee liquid, and in conventional coffee machines, only hot coffee is usually produced, but ice coffee is also popular in the market because of its unique taste.

In some conventional prior art, if ice coffee is to be made, ice cubes are generally added to the hot coffee after the hot coffee is made, or the hot coffee is to be frozen in a refrigerator, in which prior art, if ice cubes are added to the hot coffee, the taste of the coffee is affected by the added water of the ice cubes, and if the hot coffee is to be frozen in the refrigerator, additional equipment is required, and the ice coffee cannot be made simply by means of a coffee machine.

In view of this, in some prior art, a coffee machine capable of simultaneously making ice coffee and hot coffee is proposed, for example, chinese patent application No. 202110499488.7 discloses a system and a method for making ice coffee, specifically, an espresso coffee liquid dispensing mechanism is provided to dispense a coffee concentrate made by a coffee brewing mechanism into a plastic funnel or a metal funnel, when hot coffee needs to be made, the coffee concentrate on the plastic funnel falls into a beverage cup, then hot water is sent into the beverage cup through a hot water valve and a hot water pipeline of a water boiler, so as to make hot coffee, when ice coffee needs to be made, the coffee concentrate in the metal funnel is pumped into the beverage cup through a peristaltic pump, and then water in the ice water tank is sent into the beverage cup through a water pump and a tee joint, so as to make ice coffee.

However, in the above prior art, the solution adopted is to make a coffee concentrate and then mix water to form a coffee beverage, which is prone to uneven mixing of the coffee concentrate and water, resulting in poor taste, and in this process, it is necessary to provide an espresso coffee liquid dispensing mechanism below the coffee brewing mechanism, which requires a large space.

In view of the above problems, improvements are needed.

Referring to fig. 1 to 7, the present application provides a control system for making coffee, which has the following technical scheme:

For controlling the coffee machine to produce coffee, the coffee machine is provided with a hot coffee assembly 100 and an ice coffee assembly 200, and the hot coffee assembly 100 and the ice coffee assembly 200 are respectively communicated with the extraction assembly 300;

an obtaining module 810, configured to obtain a first temperature of the common pipeline 400 detected by the temperature sensor 700 when the hot coffee continuously made in the preset time period is greater than or equal to a first preset amount and is switched to making ice coffee;

the control module 820 is configured to adjust a flow parameter of the peristaltic pump 600 according to the first temperature, and control the peristaltic pump 600 to make ice coffee with the adjusted flow parameter, wherein the higher the first temperature is, the smaller the flow parameter of the peristaltic pump 600 is.

Wherein, in some embodiments, the specific relationship between the flow parameter of peristaltic pump 600 and the first temperature is:

；

Where Q represents the flow parameter of the peristaltic pump 600, T represents the first temperature, J represents the first preset parameter, and the value of J may be obtained specifically through experimental testing, and in some preferred embodiments, a table may be established that corresponds to the first temperature and the first preset parameter, i.e., the different first temperatures may correspond to the same or different first preset parameters, that is, there may be a plurality of first preset parameters, but the flow parameter of the peristaltic pump 600 and the first temperature still maintain an inverse relationship.

Referring to fig. 2, the hot coffee assembly 100 may specifically include a first pipe 110 and a first switch 120, wherein the first pipe 110 is connected to a reversing valve 500, and when hot coffee is required to be made, a peristaltic pump 600 pumps coffee liquid extracted by the extraction assembly 300 to the first pipe 110 through the reversing valve 500, and then drops into a cup through the first switch 120.

The ice coffee assembly 200 may specifically include a second pipe 210, a cooling module and a second switch 220, the cooling module includes a compressor 240, a condenser 250 and an evaporator 230, the second pipe 210 extends from the reversing valve 500 and then enters the evaporator 230, and then comes out of the evaporator 230 to be connected with the second switch 220, and the coffee liquid in the second pipe 210 may exchange heat in the evaporator 230 to achieve a cooling effect, and then falls into a cup from the second switch 220.

The directional valve 500 may specifically be an electromagnetic directional valve, and the peristaltic pump 600 pumps coffee to the hot coffee assembly 100 by controlling the directional valve 500 to communicate the common line 400 with the first conduit 110 when making hot coffee, and the peristaltic pump 600 pumps coffee to the ice coffee assembly 200 by controlling the directional valve 500 to communicate the common line 400 with the second conduit 210 when making ice coffee.

Wherein peristaltic pump 600 operates at a higher flow rate parameter when making hot coffee and at a lower flow rate parameter when making iced coffee.

In the prior art, as disclosed in the chinese patent application No. 202110499488.7, a plastic funnel and a metal funnel are provided to receive the prepared coffee concentrate, and then the coffee concentrate is diluted with water to obtain a coffee beverage product, however, this method is easy to mix unevenly with the concentrated coffee, especially when making ice coffee, due to low temperature, the thermal movement of molecules is slower, and the problem of poor taste caused by uneven mixing is more easy to occur, and due to the need of providing a dispensing mechanism, a plastic funnel and a metal funnel, the space layout of internal parts is not facilitated, and the space occupation is large.

In order to achieve better coffee taste, the application adopts the method of directly extracting all coffee liquid from the extraction assembly 300, and does not need to be diluted with water in later period, thereby avoiding the problem of uneven mixing and further ensuring the taste of coffee, wherein the extraction assembly 300 mainly consists of components such as a brewing head, the extraction assembly 300 is not the key of the application in the prior art, and therefore, the specific structure of the extraction assembly is not repeated, because the application adopts the method of directly extracting all coffee liquid, the quantity of coffee liquid flowing out of the extraction assembly 300 is larger, and in general, in some conventional prior art, when a common coffee machine is used for preparing coffee, the coffee liquid extracted from the extraction assembly 300 can directly fall into a beverage cup, however, in the scheme of the application, not only hot coffee is prepared, but also ice coffee is prepared, and a mechanism for dividing the coffee liquid obtained by extraction is also required, in the prior art, the application discloses a plurality of different funnels are used for realizing the distribution and division of the coffee liquid, however, the method is only suitable for the method of directly extracting all coffee liquid, and the quantity of the coffee liquid is easy to occupy a large quantity of the funnel, and the problem of overflow condition occurs if the quantity of coffee liquid is large, and the quantity of coffee liquid is easy to occupy a large quantity of space.

In this regard, the present application proposes to provide the common pipeline 400, preferably, the common pipeline 400 is a hose, by setting the common pipeline 400, the large-flow coffee liquid can be buffered, the problem of overflow caused by overlarge flow of the coffee liquid is avoided, and the other end of the common pipeline 400 is directly provided with the reversing valve 500 to realize the diversion of the coffee liquid, the space occupation of the reversing valve 500 is small, the space saving effect can be achieved, and meanwhile, under the condition that the common pipeline 400 is provided, the extracted coffee liquid can be guided to a proper position by using the common pipeline 400, and then the reversing valve 500 is arranged at a proper position, so that the arrangement of the internal parts of the coffee machine can be facilitated, the reasonable space layout can be obtained, and the whole space occupation of the coffee machine can be further reduced.

In general, in order to make the common pipeline 400 buffer more coffee liquid, the common pipeline 400 may be arranged to be relatively slender, so that the coffee liquid can be buffered, and at the same time, the pipe diameter is reduced to be beneficial to space layout, preferably, in order to facilitate space layout, the common pipeline 400 is a hose, so that a proper position can be found in a gap of an internal space of the coffee machine to place the common pipeline 400.

The application can improve the convenience of the space layout of the internal parts of the coffee machine under the condition of meeting the requirements of making hot coffee and ice coffee by arranging the common pipeline 400, and is beneficial to reducing the whole size of the coffee machine.

Because the common pipeline 400 is provided, the coffee machine can produce hot coffee and ice coffee, during the production of ice coffee, the extracted coffee liquid is usually cooled rapidly to obtain ice coffee, in this process, the lower the temperature of the coffee liquid entering the ice coffee assembly 200 is, the more favorable for producing ice coffee, the common pipeline 400 provided by the application can facilitate the arrangement of parts to obtain reasonable space layout, so that the whole space occupation of the coffee machine is reduced, and the function of cooling the coffee liquid can be achieved when the coffee liquid is conveyed through the common pipeline 400, so that the ice coffee can be produced by the following ice coffee assembly 200.

Since the common line 400 conveys the coffee liquid to the hot coffee assembly 100 in addition to the ice coffee assembly 200, and the hot coffee does not need to cool the coffee liquid, and the coffee liquid can be directly discharged to be a finished coffee beverage, the coffee liquid can be discharged as fast as possible when making the hot coffee, that is, the flow rate parameter of the peristaltic pump 600 can be set to be large when making the hot coffee, thereby improving the efficiency of making the hot coffee.

However, when hot coffee and ice coffee are made, the coffee liquid needs to flow through the common pipeline 400, and the temperature of the coffee liquid extracted from the extraction component 300 is higher, so that when the coffee liquid flows through the common pipeline 400, the temperature of the common pipeline 400 is increased, and when the temperature of the coffee liquid entering the ice coffee component 200 is lower and better when the ice coffee is made, the coffee liquid can originally perform the cooling function in the process of conveying the common pipeline 400, however, when the hot coffee is made, the peristaltic pump 600 pumps the coffee liquid with larger flow parameters for improving the efficiency, and the temperature of the common pipeline 400 is quickly increased, particularly when the hot coffee is continuously made, because the hot coffee is made faster, and the common pipeline 400 is arranged to be slender, a hose is generally adopted, so that the hot coffee is easy to accumulate, and the common pipeline 400 cannot dissipate heat in time after the temperature is increased, if the ice coffee is converted, the coffee liquid cannot be effectively cooled in the common pipeline 400, and the ice coffee component 200 is unfavorable to the subsequent ice coffee is made.

Specifically, the ice coffee assembly 200 is mainly cooled by cooling the coffee liquid in a refrigeration manner, in some embodiments, the ice coffee assembly 200 may adopt a constant-power operation mode, typically, the amount of the coffee liquid extracted from the extraction assembly 300 is relatively fixed, for example, the small cup is 500ml, the large cup is 800ml, and the temperature of the coffee liquid flowing out of the extraction assembly is relatively constant, while in order to ensure stable refrigeration effect, the ice coffee assembly 200 may adopt a constant-power operation mode, for example, when the order is the small cup, the coffee liquid is 500ml, at the moment, the operating power of the ice coffee assembly 200 is one kw, the refrigeration time is 5 minutes, and when the order is the large cup, the coffee liquid is 800ml, at the moment, the operating power of the ice coffee assembly 200 is one thousand hundred watts, the refrigeration time is eight minutes, and generally, the stability of the refrigeration effect can be ensured by adopting constant-power refrigeration, and the fluctuation of the power is avoided to cause the manufacturing time and the refrigeration effect of the ice coffee to fluctuate.

However, since the common pipeline 400 is provided, after the hot coffee is continuously made for a plurality of times, the temperature of the common pipeline 400 is increased, so that the coffee liquid cannot be effectively cooled in the common pipeline 400 when the ice coffee is made, or the cooling effect cannot reach the preset effect, and the temperature fluctuation of the finally made ice coffee is relatively large after the coffee liquid enters the ice coffee assembly 200, the temperature of the ice coffee is easily higher than the qualified temperature, for example, the qualified temperature is less than 8 ℃, and in the case, the temperature of the made ice coffee is possibly 10 ℃ and 12 ℃, and the like, and the influence on the coffee caused by the small temperature change can be tasted for some coffee lovers, so that bad customer experience is caused.

It should be noted that, when hot coffee and iced coffee are made at intervals, or when hot coffee is made continuously, or when hot coffee is made intermittently, the coffee solution will raise the common pipeline 400, but the temperature of the common pipeline 400 is raised to a limit that does not make the final temperature of iced coffee unacceptable, for example, in general, the acceptable temperature of iced coffee is less than 8 ℃, if the temperature of the common pipeline 400 is low, the temperature of the final iced coffee may be 5 ℃, if the temperature of the common pipeline 400 is high, the temperature of the final iced coffee may be 7 ℃, however, if hot coffee is made continuously a plurality of times, the temperature of the common pipeline 400 is raised significantly, and the temperature of the final iced coffee may be 10 ℃.

In this regard, the present application proposes that the temperature sensor 700 is disposed on the common pipeline 400, the first temperature of the common pipeline 400 is detected by the temperature sensor 700, then the flow parameter of the peristaltic pump 600 is adjusted according to the first temperature, the flow parameter is smaller as the first temperature is higher, the flow parameter is smaller, and the heat dissipation effect of the coffee liquid in the common pipeline 400 can be improved, wherein the peristaltic pump 600 pumps the coffee liquid in a pulse manner, the flow parameter of the peristaltic pump 600 is set smaller, that is, the pulse flow pumped by the peristaltic pump 600 is smaller each time, in general, the peristaltic pump 600 generates pulses, which are regarded as disadvantages, and the pulse damper and other manners are generally needed to inhibit the pulses generated by the peristaltic pump 600.

In some of the embodiments described above, it is proposed to use the temperature sensor 700 to detect a first temperature on the common line 400 and then adjust the flow parameter of the peristaltic pump 600 according to the first temperature, however, this requires that the temperature sensor 700 be continuously operated to always acquire the temperature of the common line 400.

In the practical application process, the temperature of the common pipeline 400 is generally raised to a certain extent only when hot coffee is continuously produced in a short time, and when ice coffee is produced without effective heat dissipation, the temperature of the common pipeline 400 is obviously affected after the temperature is raised, so that the temperature of coffee liquid in the transmission process of the common pipeline 400 is obviously affected, and the subsequent ice coffee production of the ice coffee assembly 200 is further affected.

Therefore, in some preferred embodiments, the temperature sensor 700 is only made to detect the first temperature of the common pipeline 400 when the hot coffee continuously made in the preset time period is not less than the first preset amount and then is switched to make the ice coffee, so that the energy consumption can be reduced.

In addition, if the temperature of the coffee liquid entering the iced coffee assembly 200 is high, it is desired to cool the coffee liquid to a preset temperature, it is necessary to increase the cooling power of the iced coffee assembly 200, and at the same time, it is also possible to lengthen the cooling time of the coffee liquid in the iced coffee assembly 200, and if it is desired to lengthen the cooling time of the coffee liquid in the iced coffee assembly 200, it is necessary to lengthen the dimensions of the second duct 210 and the evaporator 230, thereby increasing the overall size of the coffee machine, and by the scheme of the present application, the above-mentioned problems can be avoided.

In summary, the present application can convey the coffee extracted by the extraction assembly 300 to a reasonable space position by providing the common pipeline 400 on the hot coffee assembly 100 and the iced coffee assembly 200, and then provide the reversing valve 500 at the reasonable space position, so that the coffee enters the hot coffee assembly 100 or the iced coffee assembly 200, and the space layout can be more reasonable, and space occupation can be reduced, on the basis that the common pipeline 400 is provided, the coffee extracted by the extraction assembly 300 can be directly discharged when the hot coffee is produced, and the coffee extracted by the extraction assembly 300 needs to be cooled when the iced coffee is produced, generally, because the coffee extracted by the extraction assembly 300 needs to be conveyed in the common pipeline 400, the temperature of the coffee can be reduced during the process, the application is beneficial to cooling the coffee by the following ice coffee assembly 200, and if the temperature of the common pipeline 400 is increased after continuously making a large amount of hot coffee, thereby reducing the heat dissipation effect of the coffee in the conveying process of the common pipeline 400 and affecting the quality of the ice coffee made by the following ice coffee assembly 200, in this application, the peristaltic pump 600 and the temperature sensor 700 are arranged on the common pipeline 400, when the continuously made hot coffee is equal to or greater than a first preset amount in a preset period of time and is switched to making the ice coffee, the first temperature of the common pipeline 400 detected by the temperature sensor 700 is obtained, the flow parameter of the peristaltic pump 600 is adjusted according to the first temperature, the smaller the flow parameter is, the heat dissipation of the coffee in the conveying process of the common pipeline is more beneficial, thereby reducing the temperature of the coffee when entering the ice coffee assembly 200, the ice coffee making quality is ensured under the condition that the power consumption of the ice coffee assembly 200 is kept unchanged, so the scheme of the application has the beneficial effects of good taste of the coffee to be made, small space occupation and low energy consumption.

In addition, in some preferred embodiments, a cooling fan may be further provided to cool the common pipeline 400, so that the cooling fan may not be operated when the hot coffee is made in order to reduce energy consumption because the hot coffee does not need to be cooled, and the cooling fan is controlled to operate to cool the common pipeline 400 when the ice coffee is made, thereby reducing the temperature when the coffee liquid enters the ice coffee assembly 200.

In addition, in some preferred embodiments, a water storage tank may be further provided, where the water storage tank is used for storing condensed water generated in the ice coffee assembly 200 during the refrigeration process, then the water storage tank is communicated with the common pipeline 400 through a pipeline, and a valve is provided on the pipeline, and when the temperature of the common pipeline 400 is too high, the condensed water in the water storage tank can be pumped to the common pipeline 400 through the water pump, so that the pipeline is cleaned and the cooling effect of the common pipeline 400 is achieved.

Further, referring to fig. 4, in some of these embodiments, the control module 820 includes:

a first control unit 821 for adjusting a flow parameter of the peristaltic pump 600 according to the first temperature when the first temperature is less than a first preset value;

The second control unit 822 is configured to send out a first prompt message that the current coffee machine is not recommended to make ice coffee when the first temperature is greater than or equal to a first preset value.

In some embodiments, it is proposed to adjust the flow parameter of the peristaltic pump 600 according to the first temperature, so that the coffee liquid is effectively cooled in the common pipeline 400, thereby facilitating the making of the iced coffee by the iced coffee assembly 200, however, if the first temperature is too high, the temperature of the coffee liquid when being delivered to the iced coffee assembly 200 is still too high, and still adverse to the making of the iced coffee by the iced coffee assembly 200, at this time, a first prompt message may be sent to suggest that the user does not recommend the use of the current coffee machine to make the iced coffee, suggest that the user replace the coffee machine to make the iced coffee, or wait for a period of time to make the iced coffee.

However, there is a predetermined qualification time, for example, the hot coffee making time is 3 minutes, the ice coffee making time is 6 minutes, if the waiting time is too long, the order receiving is not favored, and the waiting time of customers purchasing the ice coffee is long, resulting in bad experiences, so that the priority of the waiting time is reduced, and if the temperature of the coffee liquid entering the ice coffee assembly 200 is high, the making time is long, and if the temperature of the coffee liquid entering the ice coffee assembly 200 is high, the second pipe 210 and the evaporator 230 are required to be long, and if the constant power and the constant time are set, the temperature of the ice coffee is not up to standard.

Therefore, in the scheme of the application, the first prompt message that the current coffee machine is not recommended to be used for making the ice coffee is sent out when the first temperature is larger than or equal to a first preset value.

Specifically, referring to fig. 5, the second control unit 822 includes:

a first generating subunit 823, configured to generate a first flow parameter of the peristaltic pump 600 when the first temperature is greater than or equal to a first preset value;

a first calculating subunit 824, configured to calculate first time information required for making ice coffee according to the first flow parameter;

the first sending subunit 825 is configured to send out a first prompt message that does not suggest to use the current coffee maker to make ice coffee when the first time information is greater than the second preset value.

Calculating first time information of making ice coffee through the first flow parameter, if the first time information is larger than a second preset value, the first time information is overlong, so that a customer buying ice coffee has longer waiting time and is easy to generate bad customer experience, and therefore, a first prompt message which does not suggest to use the current coffee machine to make ice coffee is sent out under the condition.

Specifically, the cooling power of the ice coffee assembly 200 may be defaulted to be constant when calculating the first time information using the first flow parameter.

Further, referring to fig. 6, in some of the embodiments, the second control unit 822 further includes:

a first adjustment subunit 826, configured to generate a power adjustment parameter of the iced coffee assembly 200 according to the first time information when the first temperature is greater than or equal to a first preset value and the iced coffee is still selected to be made;

a second generating subunit 827, configured to generate a second prompt message according to the power adjustment parameter;

the first control subunit 828 is configured to obtain first feedback information from the user according to the second prompting information, and control the iced coffee assembly 200 to make iced coffee according to the power adjustment parameter when the first feedback information is the consent adjustment.

When the power adjustment parameter of the iced coffee assembly 200 is generated according to the first time information, the time required for making the iced coffee by using the generated power adjustment parameter does not exceed the second preset value, that is, if the first time information is longer, the power adjustment parameter of the iced coffee assembly 200 is larger, because the longer the first time information is, the higher the temperature is, the more difficult it is to cool, and therefore, the greater the cooling power needs to be adjusted, so that the time required for making the iced coffee can be ensured not to exceed the second preset value.

Wherein, in some embodiments, the specific relationship between the power adjustment parameter and the first time information is:

；

wherein P represents the power adjustment parameter, t represents the first time information, K represents the second preset parameter, and the value of K can be obtained specifically through experimental tests, specifically, in some preferred embodiments, a table corresponding to the second preset parameter and the first time information may be established, that is, different first time information may correspond to the same or different second preset parameters, that is, there may be a plurality of second preset parameters, but a proportional relationship between the power adjustment parameter and the first time information is still maintained.

In some embodiments described above, it is proposed that if the first time information is greater than the second preset value, a first prompt message is sent that the current coffee machine is not recommended to make ice coffee, because in this case, the first time information is too long, and a bad customer experience is easily generated, at this time, the other coffee machines may be replaced to make ice coffee, and if the other coffee machines are busy, a longer waiting time is required, or there are no more other coffee machines, at this time, the current coffee machine is still selected to make ice coffee, the power adjustment parameter of the ice coffee assembly 200 may be generated according to the first time information, and a second prompt message is generated that reminds the user that the power of the ice coffee assembly 200 may be adjusted to accelerate the making time of ice coffee, and if the user agrees, the ice coffee assembly 200 is controlled to make ice coffee with the power adjustment parameter.

Further, referring to fig. 7, in some of these embodiments, the first control subunit 828 includes:

a first control element 829 for controlling the iced coffee assembly 200 to make iced coffee at the power adjustment parameter when the power adjustment parameter does not exceed the maximum power of the iced coffee assembly 200;

the second control element 8210 is configured to control the first emitting subunit 825 to emit a first prompting message that the current coffee maker is not recommended to make ice coffee when the power adjustment parameter exceeds the maximum power of the ice coffee assembly 200.

If the first time information is greater than the second preset value, the first time information is excessively long, which causes long waiting time of customers purchasing ice coffee and is easy to generate bad customer experience, in this case, the making speed of ice coffee can be increased by adjusting the power of the ice coffee assembly 200, however, if the power adjustment parameter required by the ice coffee assembly 200 is calculated to make ice coffee meeting the requirement within the range of the second preset value to exceed the maximum power of the ice coffee assembly 200, at this time, the first prompt information that the customers not suggesting to use the current coffee machine to make ice coffee is sent out, and the customers purchasing ice coffee are prevented from waiting excessively long time.

Specifically, the first control element 829 controls the ice coffee assembly 200 to make ice coffee with the power adjustment parameter if the power adjustment parameter does not exceed the maximum power of the ice coffee assembly 200 when the first feedback information is the approval adjustment.

Specifically, the second control element 8210 controls the first sending subunit 825 to send a first prompting message that the current coffee maker is not recommended to make ice coffee if the power adjustment parameter exceeds the maximum power of the ice coffee assembly 200 when the first feedback information is the consent adjustment
