[0067] A beverage dispenser heats a brewing liquid (such as water) and passes the heated brewing liquid through a brewing handle containing ingredients to be brewed (such as coffee powder or tea leaves), where it is quickly extracted to prepare the beverage. During the beverage preparation process, the dispenser needs to be preheated to avoid using a cold brewing liquid to extract the beverage, which could affect the quality of the drink.

[0068] The inventors of the present application have found that if a single preheating mode is used, the preheating effect is relatively mediocre. Therefore, how to improve the preheating process of the beverage machine has become an important technical problem.

[0069] To solve at least one of the above technical problems, an embodiment of the present application provides a beverage machine control method and a beverage machine.

[0070] The beverage machine provided by the present application is described in detail below with reference to the accompanying drawings.

[0071] Exemplarily, the beverage machine may be a coffee machine, and specifically, the beverage machine may be a semi-automatic coffee machine.

[0072] Figure 1 This is a structural schematic diagram of a beverage machine provided in an embodiment of the present application.

[0073] like Figure 1 As shown in , the beverage machine includes a beverage machine body 110 , an outlet assembly 120 fixedly disposed on the beverage machine body 110 , and a brewing handle 130 detachably mounted on the outlet assembly 120 .

[0074] The brewing handle 130 is a portable container capable of containing brewing materials (such as coffee powder) and is detachably connected to the outlet assembly 120. After the brewing handle 130 is installed, the outlet assembly 120 can form a sealed connection with the brewing handle 130, and the brewing liquid output by the outlet assembly 120 to the brewing handle 130 can extract the brewing materials in the brewing handle 130.

[0075] Figure 2 The internal liquid path diagram of the beverage machine provided by the embodiment of the present application.

[0076] As shown in Figure 2 The beverage machine further includes a liquid supply source 140 and a heater 150.

[0077] The liquid supply source 140 is used to supply brewing liquid.

[0078] The heater 150 is used to heat the brewing liquid. The heater 150 can be in communication with the outlet assembly 120 through a liquid supply pipeline 160.

[0079] The liquid supply pipeline 160 is provided downstream with a first liquid outlet pipeline 161 and a second liquid outlet pipeline 162. The liquid supply pipeline 160 selectively communicates with the first liquid outlet pipeline 161 or the second liquid outlet pipeline 162. The first liquid outlet pipeline 161 communicates with a liquid storage tray 163 of the beverage machine, and the second liquid outlet pipeline 162 communicates with the outlet assembly 120 of the beverage machine.

[0080] The liquid storage tray 163 is used to contain waste water generated by the beverage machine.

[0081] When the liquid supply pipeline 160 communicates with the first liquid outlet pipeline 161, the brewing liquid output by the heater 150 can be output to the liquid storage tray 163 through the liquid supply pipeline 160 and the first liquid outlet pipeline 161.

[0082] When the liquid supply pipeline 160 communicates with the second liquid outlet pipeline 162, the brewing liquid output by the heater 150 can be output to the outlet assembly 120 through the liquid supply pipeline 160 and the second liquid outlet pipeline 162, and finally supplied to the brewing handle 130 for beverage extraction, or directly discharged from the beverage machine through the outlet assembly 120.

[0083] The liquid supply pipeline 160 can be provided with a first electric control valve 164, which selectively communicates with the first liquid outlet pipeline 161 or the second liquid outlet pipeline 162.

[0084] The beverage machine can further include a temperature detector 165, which is arranged at the liquid outlet of the heater 150 and is used to detect the temperature of the brewing liquid output by the heater 150.

[0085] Figure 3A flowchart of a control method of a beverage machine is provided in the embodiments of the present application. As shown in Figure 3 The method can mainly include the following steps.

[0086] Step S310: In response to a beverage preparation instruction, determine whether the brewing handle 130 is installed on the outlet assembly 120 of the beverage machine.

[0087] Step S320: In response to the brewing handle 130 being installed on the outlet assembly 120, start a first preheating mode.

[0088] Step S330: In response to the brewing handle 130 not being installed on the outlet assembly 120, start a second preheating mode, wherein the first preheating mode is different from the second preheating mode.

[0089] The user can trigger the beverage preparation instruction in various ways, including but not limited to pressing the extraction button of the beverage machine.

[0090] In the embodiments of the present application, after detecting the beverage preparation instruction, it can be detected whether the brewing handle 130 is installed on the outlet assembly 120. When it is determined that the brewing handle 130 is installed on the outlet assembly 120, the first preheating mode can be started. When it is determined that the brewing handle 130 is not installed on the outlet assembly 120, the second preheating mode can be started. When the brewing handle 130 of the beverage machine is in different installation states (installed state or not installed state), the functional characteristics of the beverage machine are different, so that the demand for the preheating mode is also different. The first preheating mode is a preheating mode designed for the installed state of the brewing handle 130, which can match the functional characteristics of the beverage machine in the installed state of the brewing handle 130, ensure that the beverage machine can be preheated in the installed state of the brewing handle 130, and achieve good preheating effect. Correspondingly, the second preheating mode is a preheating mode designed for the not installed state of the brewing handle 130, which can match the functional characteristics of the beverage machine in the not installed state of the brewing handle 130, ensure that the beverage machine can be preheated in the not installed state of the brewing handle 130, and achieve good preheating effect.

[0091] In related technologies, the beverage machine generally adopts a single preheating mode, which cannot dynamically adjust the preheating mode according to the actual installation state of the brewing handle 130, resulting in poor preheating effect of the beverage machine. The present scheme can dynamically adjust to the preheating mode matched with the installation state of the brewing handle 130 according to the installation state of the brewing handle 130, thereby effectively improving the preheating effect of the beverage machine.

[0092] The method provided by the embodiment of the application can determine whether the brewing handle 130 is installed on the outlet assembly 120 of the beverage machine in response to the beverage preparation instruction, and start a first preheating processing mode when the brewing handle 130 is installed on the outlet assembly 120, and start a second preheating processing mode different from the first preheating processing mode when the brewing handle 130 is not installed on the outlet assembly 120. Based on the scheme, the matching preheating processing mode can be dynamically adjusted according to the different installation states of the brewing handle 130, and the different installation states of the brewing handle 130 are adapted by providing diversified preheating processing modes, so that the preheating effect of the beverage machine is effectively improved.

[0093] In an optional mode of the embodiment of the application, the beverage machine comprises a liquid supply pipeline 160 and a heater 150, the liquid supply pipeline 160 is connected to the heater 150 and the outlet assembly 120, and the liquid supply pipeline 160 is used to supply brewing liquid to the outlet assembly 120.

[0094] The first preheating processing mode comprises:

[0095] The heater 150 is controlled to work, and whether the temperature of the brewing liquid in the liquid supply pipeline 160 reaches a preset brewing temperature is detected.

[0096] In the embodiment of the application, when the brewing handle 130 is installed on the outlet assembly 120, the first preheating processing mode can be started to ensure the preheating effect, and the first preheating processing mode at least comprises: the heater 150 is controlled to work, and whether the temperature of the brewing liquid in the liquid supply pipeline 160 reaches a preset brewing temperature is detected.

[0097] The preset brewing temperature is the hot extraction temperature of the beverage, and when the temperature of the brewing liquid in the liquid supply pipeline 160 is lower than the preset brewing temperature, the extraction temperature is low, and the extraction effect is affected.

[0098] After the heater 150 works, the brewing liquid is heated by the heater 150, and the heated brewing liquid enters the liquid supply pipeline 160. Whether the temperature of the brewing liquid in the liquid supply pipeline 160 reaches the preset brewing temperature is detected, so that the preheating state of the pipeline in the beverage machine is judged, thereby providing a basis for the respective subsequent processing of the first preheating processing mode according to the different preheating states of the pipeline in the beverage machine.

[0099] Exemplarily, a temperature detector 165 can be arranged at the liquid outlet of the heater 150, and whether the temperature of the brewing liquid in the liquid supply pipeline 160 reaches the preset brewing temperature is judged based on the detection data of the temperature detector 165.

[0100] In an optional mode of the embodiment of the application, the beverage machine further comprises a first liquid outlet pipeline 161 and a second liquid outlet pipeline 162 arranged downstream of the liquid supply pipeline 160, the liquid supply pipeline 160 selectively communicates with the first liquid outlet pipeline 161 or the second liquid outlet pipeline 162, the first liquid outlet pipeline 161 communicates with a liquid storage tray 163 of the beverage machine, and the second liquid outlet pipeline 162 communicates with the outlet assembly 120 of the beverage machine.

[0101] When the temperature of the brewing liquid in the liquid supply pipeline 160 does not reach the preset brewing temperature, the first preheating mode is started, and the method further comprises: controlling the brewing liquid in the liquid supply pipeline 160 to be discharged into the liquid storage tray 163 through the first liquid outlet pipeline 161.

[0102] When the temperature of the brewing liquid in the liquid supply pipeline 160 reaches the preset brewing temperature, the first preheating mode is started, and the method further comprises: controlling the brewing liquid in the liquid supply pipeline 160 to be supplied to the brewing handle 130 through the second liquid outlet pipeline 162 and the outlet assembly 120.

[0103] When the brewing handle 130 has been installed and the temperature of the brewing liquid in the liquid supply pipeline 160 does not reach the preset brewing temperature, it indicates that the pipeline in the beverage machine is not sufficiently preheated, which may be because the pipeline in the beverage machine has not been used for a long time and low-temperature brewing liquid exists in the pipeline, or the brewing liquid has not been sufficiently heated in the heater 150 before being output. At this time, in the first preheating mode, the brewing liquid in the liquid supply pipeline 160 can be controlled to be discharged into the liquid storage tray 163 through the first liquid outlet pipeline 161.

[0104] When the brewing handle 130 has been installed and the temperature of the brewing liquid in the liquid supply pipeline 160 does not reach the preset brewing temperature, by controlling the brewing liquid in the liquid supply pipeline 160 to be discharged into the liquid storage tray 163, the preheating of the pipeline in the beverage machine can be achieved, and at the same time, the brewing liquid at a relatively low temperature can be prevented from being supplied to the brewing handle 130 through the outlet assembly 120, so as to avoid the use of the brewing liquid at a relatively low temperature for extraction, thereby affecting the extraction quality.

[0105] In the embodiment of the application, when the temperature of the brewing liquid in the liquid supply pipeline 160 reaches the preset brewing temperature, it indicates that the pipeline in the beverage machine has been sufficiently preheated, which can ensure that the output brewing liquid maintains a relatively high temperature and guarantees the extraction quality. Therefore, at this time, the brewing liquid in the liquid supply pipeline 160 can be controlled to be supplied to the brewing handle 130 through the second liquid outlet pipeline 162 and the outlet assembly 120, thereby realizing the high-quality preparation of the beverage.

[0106] In the state that the brewing handle 130 is installed, the first preheating processing mode can be executed, the temperature of the brewing liquid in the liquid supply pipeline 160 is detected, the low-temperature brewing liquid is automatically controlled to be guided out to the liquid storage disc 163, the influence on the extraction quality caused by the output of the low-temperature brewing liquid is avoided, and the brewing liquid reaching the preset extraction temperature is automatically controlled to be output to the brewing handle 130, so as to ensure the optimal extraction quality.

[0107] In an optional mode of the embodiment of the application, the beverage machine comprises the liquid supply pipeline 160 and the heater 150, the liquid supply pipeline 160 is connected to the heater 150 and the outlet assembly 120, and the liquid supply pipeline 160 is used to supply the brewing liquid to the outlet assembly 120.

[0108] The second preheating processing mode is started, which comprises:

[0109] The heater 150 is controlled to work, and the brewing liquid in the liquid supply pipeline 160 is controlled to be supplied to the outlet assembly 120 and discharged from the beverage machine through the outlet assembly 120.

[0110] In the case that the brewing handle 130 is not installed on the outlet assembly 120, even if the beverage machine receives the beverage preparation instruction, the beverage extraction cannot be performed, and the beverage extraction can be performed only after the brewing handle 130 is installed by the user.

[0111] In the case that the beverage machine receives the beverage preparation instruction and the brewing handle 130 is not installed on the outlet assembly 120, it can be predicted that the new user has the intention to brew the beverage, and it is extremely likely that the brewing handle 130 is installed and the beverage is brewed in the subsequent operation, at this time, the second preheating processing mode can be started to preheat the beverage machine early before the beverage is prepared, improve the preheating efficiency, and obtain better preheating effect. It can also be predicted that it is the intentional action of the experienced user. For the experienced user, it is a routine operation to preheat the pipeline (such as the liquid supply pipeline 160 and the outlet assembly 120) in the beverage machine before the brewing handle 130 is installed to brew the beverage. After the pipeline (such as the liquid supply pipeline 160 and the outlet assembly 120) in the beverage machine is preheated, the brewing handle 130 is installed to brew the beverage, which can ensure the brewing temperature of the material to be brewed, and thus ensure the brewing quality.

[0112] In a case that the beverage machine receives a beverage preparation instruction and the brewing handle 130 is not installed on the outlet assembly 120, a second preheating processing mode is started, and the second preheating processing mode is specifically: the heater 150 is controlled to work, and the brewing liquid in the liquid supply pipeline 160 is controlled to be supplied to the outlet assembly 120 and discharged from the beverage machine through the outlet assembly 120. By controlling the heated brewing liquid to be discharged through the liquid supply pipeline 160 and the outlet assembly 120, the brewing liquid with a low temperature that has not been used for a long time in the liquid supply pipeline 160 can be discharged, and the effective preheating of the pipeline (such as the liquid supply pipeline 160 and the outlet assembly 120) in the beverage machine can also be realized.

[0113] In an optional mode of the embodiment of the present application, after the second preheating processing mode is started, the second preheating processing mode is terminated in response to the presence of any one of the following preset conditions, and the preset conditions include:

[0114] The temperature of the outlet assembly 120 reaches a preset temperature value;

[0115] The amount of liquid discharged through the outlet assembly 120 reaches a preset flow rate;

[0116] The execution time length of the second preheating processing mode reaches a preset time length;

[0117] A beverage preparation stop instruction.

[0118] In the second preheating processing mode, the pipeline of the beverage machine is in a preheating process. When any one of the preset conditions is present, it indicates that the beverage machine no longer needs to continue preheating, and the second preheating processing mode can be terminated.

[0119] The preset conditions can be set according to actual needs. By terminating the second preheating processing mode when any one of the preset conditions is present, the preheating process can be stopped in time, resource waste can be avoided, and the waiting time of the user can be reduced.

[0120] For example, the preset condition includes that the temperature of the outlet assembly 120 reaches a preset temperature value. The temperature of the outlet assembly 120 can reflect the temperature of the brewing liquid output by the outlet assembly 120. When the temperature of the outlet assembly 120 reaches the preset temperature value, it indicates that the temperature of the brewing liquid is no longer lower than the preset brewing temperature, and the pipeline of the beverage machine has completed preheating. At this time, the second preheating processing mode can be terminated, and the beverage can be brewed after the brewing handle 130 is installed.

[0121] It can be understood that the preset temperature value in the present example can be the same as or different from the preset brewing temperature. The numerical relationship between the preset temperature value and the preset brewing temperature can be reasonably set to ensure that when the temperature of the outlet assembly 120 reaches the preset temperature value, the temperature of the brewing liquid is no longer lower than the preset brewing temperature.

[0122] Exemplarily, a temperature sensor can be arranged at the outlet assembly 120 to detect the temperature of the outlet assembly 120.

[0123] Exemplarily, the preset condition can further include that the amount of liquid discharged via the outlet assembly 120 reaches a preset flow rate or the execution duration of the second preheating treatment mode reaches a preset duration. When the amount of liquid discharged via the outlet assembly 120 reaches the preset flow rate or the execution duration of the second preheating treatment mode reaches the preset duration, it indicates that the brewing liquid for preheating treatment is sufficient, or the duration of the preheating treatment is sufficient, and the pipeline in the beverage machine has been sufficiently preheated, at which time the second preheating treatment mode can be terminated, and the beverage can be brewed after the brewing handle 130 is installed.

[0124] The preset flow rate or execution duration can be set according to experimental values and / or empirical values, which are not limited in the present application.

[0125] Exemplarily, the preset condition can further include a beverage preparation stop instruction. When the beverage preparation stop instruction is detected, it indicates that the beverage preparation operation is not needed at present, and the preheating treatment also does not need to be continued, at which time the second preheating treatment mode can be terminated.

[0126] In an optional manner of the embodiments of the present application, determining whether the brewing handle 130 is installed at the outlet assembly 120 of the beverage machine includes:

[0127] Determining, by a trigger signal output by an inductive element, whether the brewing handle 130 is installed at the outlet assembly 120 of the beverage machine, wherein the inductive element is triggered when the brewing handle 130 is installed at the outlet assembly 120.

[0128] In the embodiments of the present application, the installation state of the brewing handle 130 can be detected by arranging the inductive element, so as to ensure accurate sensing of the installation state of the brewing handle 130.

[0129] The inductive element can be triggered when the brewing handle 130 is installed at the outlet assembly 120, and output a trigger signal, based on which it can be judged that the brewing handle 130 has been installed at the outlet assembly 120 of the beverage machine. When the trigger signal is not detected, it can be judged that the brewing handle 130 is not installed.

[0130] Exemplarily, the inductive element can be various forms of in-place detection devices for detecting whether the brewing handle 130 is in place. The various forms of in-place detection devices can be mechanical detection devices that trigger signal changes through physical contact, optical detection devices that trigger detection by using changes in optical signals (such as shielding and reflection), image recognition detection devices that capture images by using a camera and analyze the existence of objects by using algorithms (such as OpenCV and deep learning), etc. As long as the in-place detection device is triggered to output a trigger signal when the brewing handle 130 is in place.

[0131] The embodiment of the present application also provides a beverage machine, which comprises a liquid supply source 140, a heater 150, an outlet assembly 120, a brewing handle 130 and a controller, wherein,

[0132] The liquid supply source 140 is configured to supply brewing liquid.

[0133] The heater 150 is connected between the liquid supply source 140 and the outlet assembly 120, and is configured to heat the brewing liquid.

[0134] The brewing handle 130 is detachably installed on the outlet assembly 120, and is configured to accommodate brewing material.

[0135] The outlet assembly 120 is connected to the heater 150 through a liquid supply pipeline 160.

[0136] The controller is configured to determine whether the brewing handle 130 is installed on the outlet assembly 120, and to start a first preheating mode in response to a beverage preparation instruction when the brewing handle 130 is installed on the outlet assembly 120, and to start a second preheating mode in response to the beverage preparation instruction when the brewing handle 130 is not installed on the outlet assembly 120, wherein the first preheating mode is different from the second preheating mode.

[0137] The liquid supply source 140 is configured to supply brewing liquid, for example, water, and can be a water tank, a bottled water or a self-watering source configured in the beverage machine.

[0138] The heater 150 is configured to heat the brewing liquid, and can be a boiler or an electric heating plate, etc.

[0139] The brewing handle 130 can accommodate brewing material, for example, coffee powder or tea powder, etc.

[0140] The controller can be various forms of control units, including but not limited to a microcontroller unit.

[0141] An inductive element can be provided to sense the installation state of the brewing handle 130.

[0142] The inductive element can be electrically connected to the controller, and is triggered when the brewing handle 130 is installed on the outlet assembly 120, and sends a trigger signal to the controller. When the controller receives the trigger signal, it can be determined that the brewing handle 130 has been installed on the outlet assembly 120 of the beverage machine, and when the controller does not receive the trigger signal, it can be determined that the brewing handle 130 has not been installed on the outlet assembly 120 of the beverage machine.

[0143] The controller can start the first preheating processing mode in response to the beverage preparation instruction when determining that the brewing handle 130 is installed on the outlet assembly 120, and start the second preheating processing mode in response to the beverage preparation instruction when determining that the brewing handle 130 is not installed on the outlet assembly 120. By dynamically adjusting to the matched preheating processing mode according to the different installation states of the brewing handle 130, the preheating effect of the beverage machine is improved, which not only improves the beverage brewing experience of novice users, but also does not affect experienced users.

[0144] In an optional mode of the embodiment of the application, the beverage machine further comprises a liquid storage disc 163 arranged downstream of the liquid supply pipeline 160, and the liquid supply pipeline 160 is selectively connected to the outlet assembly 120 and the liquid storage disc 163.

[0145] The controller can selectively control the brewing liquid output by the heater 150 to flow to the outlet assembly 120 through the liquid supply pipeline 160 and be discharged through the outlet assembly 120 to execute the second preheating processing mode when the brewing handle 130 is not installed on the outlet assembly 120, or control the brewing liquid output by the heater 150 to be discharged to the liquid storage disc 163 through the liquid supply pipeline 160 to execute the first preheating processing mode when the brewing handle 130 is installed on the outlet assembly 120.

[0146] The temperature of the brewing liquid output by the heater 150 is higher than the temperature of the liquid in the liquid supply source 140.

[0147] In the embodiment of the application, the controller can control the liquid supply pipeline 160 to be selectively connected to the outlet assembly 120 or the liquid storage disc 163 to support different preheating processing modes.

[0148] Specifically, in the second preheating processing mode, the controller can control the brewing liquid output by the heater 150 to flow to the outlet assembly 120 through the liquid supply pipeline 160 and be discharged through the outlet assembly 120, thereby preheating the pipeline of the beverage machine.

[0149] In the first preheating processing mode, the controller can control the brewing liquid output by the heater 150 to be discharged to the liquid storage disc 163 through the liquid supply pipeline 160, thereby avoiding that the low-temperature brewing liquid is supplied to the brewing handle 130 through the outlet assembly 120 to affect the extraction quality. In the process of discharging the brewing liquid output by the heater 150 to the liquid storage disc 163 through the liquid supply pipeline 160, the pipeline of the beverage machine can also be preheated to at least a certain extent.

[0150] In an optional mode of the embodiment of the application, the liquid supply pipeline 160 is selectively connected to the first liquid outlet pipeline 161 and the second liquid outlet pipeline 162 through the first electrically controlled valve 164, the first liquid outlet pipeline 161 is connected to the liquid storage disc 163, and the second liquid outlet pipeline 162 is connected to the outlet assembly 120.

[0151] The first electric control valve 164 is electrically connected with the controller. When the second preheating treatment mode is executed, the first electric control valve 164 connects the liquid supply pipeline 160 and the second liquid outlet pipeline 162. When the first preheating treatment mode is executed, the liquid supply pipeline 160 selectively connects the first liquid outlet pipeline 161 and the second liquid outlet pipeline 162 through the first electric control valve 164.

[0152] In the embodiment, the first liquid outlet pipeline 161 connected with the liquid storage tank 163 and the second liquid outlet pipeline 162 connected with the outlet assembly 120 are arranged downstream of the liquid supply pipeline 160.

[0153] The first electric control valve 164 is electrically connected with the controller and selectively connects the liquid supply pipeline 160 with the first liquid outlet pipeline 161 or the second liquid outlet pipeline 162 under the control of the controller. By arranging the first electric control valve 164, the connection state of the liquid supply pipeline 160 with the first liquid outlet pipeline 161 or the second liquid outlet pipeline 162 can be effectively controlled.

[0154] In an optional mode of the embodiment, the beverage machine comprises a temperature detector 165 arranged at the liquid outlet of the heater 150. In the first preheating treatment mode:

[0155] When the detection result of the temperature detector 165 does not reach the preset brewing temperature, the first electric control valve 164 connects the liquid supply pipeline 160 and the first liquid outlet pipeline 161, so that the brewing liquid output by the heater 150 is discharged to the liquid storage tank 163 through the liquid supply pipeline 160 and the first liquid outlet pipeline 161.

[0156] When the detection result of the temperature detector 165 reaches the preset brewing temperature, the first electric control valve 164 connects the liquid supply pipeline 160 and the second liquid outlet pipeline 162, so that the brewing liquid output by the heater 150 is supplied to the brewing handle 130 through the liquid supply pipeline 160, the second liquid outlet pipeline 162 and the outlet assembly 120.

[0157] In the embodiment, the temperature detector 165 is arranged at the liquid outlet of the heater 150, so that the temperature detector 165 can accurately detect the temperature of the brewing liquid in the liquid supply pipeline 160.

[0158] The temperature sensor can be electrically connected with the controller to send the temperature detection result to the controller. In the first preheating treatment mode, the controller can perform corresponding processing based on whether the detection result of the temperature detector 165 reaches the preset brewing temperature.

[0159] Specifically, when the detection result of the temperature detector 165 does not reach the preset brewing temperature, the controller can control the first electric control valve 164 to connect the liquid supply pipeline 160 and the first liquid outlet pipeline 161, so that the brewing liquid output by the heater 150 is discharged to the liquid storage disc 163 through the liquid supply pipeline 160 and the first liquid outlet pipeline 161, preventing the low-temperature brewing liquid from being supplied to the brewing handle 130 through the second liquid outlet pipeline 162 and the outlet assembly 120, affecting the extraction quality, and at the same time, the brewing liquid discharged to the liquid storage disc 163 through the liquid supply pipeline 160 and the first liquid outlet pipeline 161 can also preheat the pipeline of the beverage machine to at least a certain extent; when the detection result of the temperature detector 165 reaches the preset brewing temperature, the controller can control the first electric control valve 164 to connect the liquid supply pipeline 160 and the second liquid outlet pipeline 162, so that the brewing liquid output by the heater 150 is supplied to the brewing handle 130 through the liquid supply pipeline 160, the second liquid outlet pipeline 162 and the outlet assembly 120, to brew the material to be brewed in the brewing handle 130, ensuring the quality of the beverage brewing.

[0160] In an optional mode of the embodiment of the present application, the beverage machine further comprises at least one of the following features:

[0161] The beverage machine further comprises a second electric control valve 166 and a cold extraction pipeline 167, and the liquid supply source 140 is selectively connected to the heater 150 and the cold extraction pipeline 167 through the second electric control valve 166, and the cold extraction pipeline 167 is connected to the liquid supply pipeline 160.

[0162] The beverage machine further comprises a third electric control valve 168 and a hot liquid pipeline 169, and the heater 150 is selectively connected to the liquid supply pipeline 160 and the hot liquid pipeline 169 through the third electric control valve 168.

[0163] For example, referring to FIG. 1, Figure 2 As shown in FIG. 1, the beverage machine can further comprise a second electric control valve 166 and a cold extraction pipeline 167.

[0164] The cold extraction pipeline 167 is used to transport unheated brewing liquid to the brewing handle 130 for cold extraction.

[0165] The liquid supply source 140 is selectively connected to the heater 150 and the cold extraction pipeline 167 through the second electric control valve 166.

[0166] When the liquid supply source 140 is connected to the heater 150, the brewing liquid output by the liquid supply source 140 enters the heater 150 for heating, and the brewing liquid output by the heater 150 can be used for preheating treatment or for brewing beverages, i.e., hot extraction.

[0167] When the liquid supply source 140 is connected to the cold extraction pipeline 167, the brewing liquid output by the liquid supply source 140 can be finally supplied to the brewing handle 130 through the cold extraction pipeline 167 and the second liquid outlet pipeline 162, so as to cold extract the material to be brewed carried in the brewing handle 130.

[0168] The cold extraction pipeline 167 can support the beverage machine to prepare beverages in a cold extraction manner, enrich the functions of the beverage machine, and help improve the user experience.

[0169] Exemplarily, referring to Figure 2 As shown in the figure, the beverage machine can further include a third electric control valve 168 and a hot liquid pipeline 169.

[0170] The hot liquid pipeline 169 is used to directly output the heated brewing liquid output by the heater 150 for the user to use. For example, the brewing liquid is water, and the hot water is directly guided out through the hot liquid pipeline 169, so as to meet the demand of the user to directly drink hot water.

[0171] The heater 150 is selectively connected to the liquid supply pipeline 160 and the hot liquid pipeline 169 through the third electric control valve 168.

[0172] When the heater 150 is connected to the liquid supply pipeline 160, the brewing liquid output by the heater 150 can be used for preheating treatment or for brewing beverages.

[0173] When the heater 150 is connected to the hot liquid pipeline 169, the brewing liquid output by the heater 150 can be directly output through the hot liquid pipeline 169.

[0174] Figure 4 Another flowchart of a beverage machine control method provided by the embodiment of the present application is shown in the figure. As Figure 4 shown, the method can mainly include:

[0175] Step S410: In response to a beverage preparation instruction, it is determined whether the brewing handle 130 is installed on the outlet assembly 120 of the beverage machine.

[0176] Step S420: In response to the brewing handle 130 not being installed on the outlet assembly 120, a preheating operation is performed.

[0177] In which, after detecting that the user triggers the beverage preparation instruction, it can be detected whether the brewing handle 130 is installed on the outlet assembly 120. In the case that the brewing handle 130 is not installed on the outlet assembly 120, beverage brewing cannot be performed, and beverage extraction can be performed only after the user installs the brewing handle 130.

[0178] In the case that the brewing handle 130 is not installed on the outlet assembly 120 and the beverage machine receives a beverage preparation instruction, it can be predicted that the novice user has the intention to brew a beverage, and it is extremely likely that the brewing handle 130 will be installed and the beverage will be brewed in the subsequent operation. At this time, the preheating operation can be started to preheat the beverage machine early before the beverage is prepared, improve the preheating efficiency, and achieve better preheating effect. It can also be predicted that it is the intentional action of an experienced user. For experienced users, preheating the pipeline (such as the outlet assembly 120) in the beverage machine before installing the brewing handle 130 to brew a beverage is a routine operation. After preheating the pipeline (such as the outlet assembly 120) in the beverage machine, the brewing handle 130 is installed to brew a beverage, which can ensure the brewing temperature of the material to be brewed, thereby ensuring the brewing quality.

[0179] The method provided by the embodiment of the application determines whether the brewing handle 130 is installed on the outlet assembly 120 of the beverage machine in response to the beverage preparation instruction, and performs the preheating operation on the outlet assembly 120 when the brewing handle 130 is not installed on the outlet assembly 120. Based on the scheme, effective preheating processing can be performed for the case that the beverage machine does not install the brewing handle 130, and the beverage machine is preheated early before the beverage is prepared, the preheating efficiency is improved, and better preheating effect is achieved.

[0180] In an optional manner of the embodiment of the application, the beverage machine includes a heater 150, and the preheating operation includes:

[0181] The heater 150 is controlled to work, and the brewing liquid output by the heater 150 is supplied to the outlet assembly 120 and discharged through the outlet assembly 120. The temperature of the brewing liquid output by the heater 150 is higher than the temperature of the outlet assembly 120.

[0182] The heater 150 is used to heat the brewing liquid. When the preheating operation is performed, the heater 150 is controlled to work to heat the brewing liquid, so that the temperature of the brewing liquid output by the heater 150 is higher than the temperature of the outlet assembly 120.

[0183] In the case that the beverage machine receives a beverage preparation instruction and the brewing handle 130 is not installed on the outlet assembly 120, the preheating operation is started. The preheating operation specifically includes: controlling the heater 150 to work, and controlling the brewing liquid output by the heater 150 to be supplied to the outlet assembly 120 and discharged through the outlet assembly 120. By controlling the heated brewing liquid to be supplied to the outlet assembly 120 and discharged through the outlet assembly 120, the brewing liquid with low temperature that has not been used for a long time in the pipeline can be discharged, and the pipeline (such as the outlet assembly 120) in the beverage machine can also be effectively preheated.

[0184] In an optional mode of the embodiment of the present application, the preheating operation is terminated in response to any one of the following preset conditions, including:

[0185] The temperature of the outlet assembly 120 reaches a preset temperature value;

[0186] The amount of liquid discharged via the outlet assembly 120 reaches a preset flow rate;

[0187] The execution duration of the preheating operation reaches a preset duration;

[0188] A beverage preparation stop instruction.

[0189] In the process of performing the preheating operation, when the preset condition exists, it indicates that the beverage machine no longer needs to continue preheating, and the preheating operation can be terminated.

[0190] The preset condition can be set according to actual needs, and by terminating the preheating operation under the preset condition, the preheating operation can be stopped in time, and resource waste can be avoided.

[0191] For example, the preset condition includes that the temperature of the outlet assembly 120 reaches a preset temperature value. The temperature of the outlet assembly 120 can reflect the temperature of the brewing liquid output by the outlet assembly 120, and when the temperature of the outlet assembly 120 reaches the preset temperature value, it indicates that the temperature of the brewing liquid is not lower than the preset brewing temperature, and the pipeline of the beverage machine has completed preheating, at which time the preheating operation can be terminated.

[0192] For example, the preset condition can also include that the amount of liquid discharged via the outlet assembly 120 reaches a preset flow rate or the execution duration of the preheating operation reaches a preset duration. When the amount of liquid discharged by the outlet assembly 120 reaches the preset flow rate or the execution duration of the preheating operation reaches the preset duration, it indicates that the amount of brewing liquid for preheating operation is sufficient, or the duration of the preheating operation is sufficient, and the pipeline in the beverage machine has been sufficiently preheated, at which time the preheating operation can be terminated.

[0193] For example, the preset condition can also include a beverage preparation stop instruction. When the beverage preparation stop instruction is detected, it indicates that there is no need to perform beverage preparation operation at present, at which time the preheating operation can be terminated.

[0194] In an optional mode of the embodiment of the present application, the beverage machine includes a heater 150, and the above method further includes:

[0195] In response to the brewing handle 130 being installed on the outlet assembly 120, detecting whether the temperature of the brewing liquid output by the heater 150 reaches a preset brewing temperature;

[0196] In response to the temperature of the brewing liquid output by the heater 150 not reaching the preset brewing temperature, the brewing liquid output by the heater 150 is controlled to be discharged to the liquid storage tray 163 of the beverage machine; in response to the temperature of the brewing liquid output by the heater 150 reaching the preset brewing temperature, the brewing liquid output by the heater 150 is controlled to be supplied to the brewing handle 130 through the outlet assembly 120.

[0197] In the embodiment of the present application, when the brewing handle 130 is installed on the outlet assembly 120, it can be detected whether the temperature of the brewing liquid output by the heater 150 reaches the preset brewing temperature. When the temperature of the brewing liquid output by the heater 150 does not reach the preset brewing temperature, it indicates that the pipeline in the beverage machine has not been preheated, which may be because the pipeline in the beverage machine has not been used for a long time and there is low-temperature brewing liquid in the pipeline, or the brewing liquid has not been sufficiently heated in the heater 150 before being output. At this time, the brewing liquid output by the heater 150 can be controlled to be discharged to the liquid storage tray 163.

[0198] When the brewing handle 130 has been installed and the temperature of the brewing liquid output by the heater 150 does not reach the preset brewing temperature, by controlling the brewing liquid output by the heater 150 to be discharged to the liquid storage tray 163, the pipeline in the beverage machine can be preheated, and at the same time, the brewing liquid with a lower temperature can be prevented from being supplied to the brewing handle 130 through the outlet assembly 120, so as to avoid the use of the brewing liquid with a lower temperature for extraction, which affects the quality of the beverage.

[0199] In the embodiment of the present application, when the temperature of the brewing liquid output by the heater 150 reaches the preset brewing temperature, it indicates that the pipeline in the beverage machine has been sufficiently preheated, which can ensure that the output brewing liquid maintains a high temperature and ensures the extraction quality. Therefore, at this time, the brewing liquid output by the heater can be directly controlled to be supplied to the brewing handle 130 through the outlet assembly 120, so as to realize the high-quality preparation of the beverage.

Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and they can be executed in other sequences.

[0201] The above merely describes some embodiments of the present application, and it should be pointed out that, for those skilled in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as falling within the protection scope of the present application.
