Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a coffee machine and a coffee brewing method. Background Art

[0002] With the global prevalence of coffee culture, coffee machines have become a common fixture in homes, offices, and various dining venues. However, most coffee machines currently on the market have functional limitations and relatively limited brewing functions. With consumers' evolving pursuit of coffee quality and experience, coupled with the growing trend of diversification in the coffee market, the limited brewing functions of coffee machines and their inability to meet diverse brewing scenarios are becoming increasingly prominent. Technological innovation and functional expansion are urgently needed to provide users with a richer, more personalized coffee brewing experience. Summary of the Invention

[0003] Based on this, it is necessary to provide a coffee machine and a coffee brewing method to address the problem that the coffee machine has a single function.

[0004] A coffee machine includes: a shell assembly, the shell assembly being provided with a mounting cavity; a liquid supply assembly, the liquid supply assembly being arranged on the shell assembly and at least partially located in the mounting cavity; a heating assembly, the heating assembly being arranged on the shell assembly and at least partially located in the mounting cavity, the heating assembly being communicated with the liquid supply assembly; a brewing system, the brewing system being arranged on the shell assembly and communicating with the heating assembly; and a hand brewing assembly, the hand brewing assembly being detachably arranged on the shell assembly and communicating with the heating assembly.

[0005] The coffee machine disclosed in this application utilizes a liquid supply assembly, a heating assembly, and a brewing system, interconnected in sequence, to form a complete and efficient coffee brewing process. The liquid supply assembly stores and delivers water to the heating assembly, which quickly heats the water to the appropriate temperature before delivering it to the brewing system. In the brewing system, the hot water fully contacts and extracts the coffee grounds, producing delicious coffee. This design ensures a stable supply of water flow and heat during the coffee-making process, enabling precise control of the extraction time and temperature. The pour-over assembly is detachable from the housing assembly and connected to the heating assembly, providing users with a variety of coffee-making options. Users can quickly prepare standard coffee drinks using the brewing system, or remove the pour-over assembly and enjoy the pleasure of pour-over coffee. The pour-over assembly meets the personalized coffee-making needs of different users. For those who prefer a slower pace and a richer coffee flavor, the pour-over assembly allows them to customize factors such as water flow rate and brewing time to create unique pour-over coffee, enriching the coffee machine's functionality and usage scenarios. Each component is mounted on the housing assembly and partially located within the mounting cavity, resulting in a compact overall structure for the coffee machine. This compact layout design integrates all the functional modules required for coffee making into a relatively small space. The mounting cavity provides ample space for the liquid supply assembly, heating element, and other components, effectively utilizing the internal space of the housing assembly. By partially placing these components within the mounting cavity, they ensure secure installation while avoiding excessive exposure and space occupation, resulting in a more streamlined and aesthetically pleasing overall appearance for the coffee machine.

[0006] In one embodiment, the hand-brew component includes a brewing faucet and a pipe, and the brewing faucet is detachably provided on the shell assembly, one end of the pipe is connected to the brewing faucet, and the other end of the pipe is connected to the heating assembly. By detachably providing the brewing faucet on the shell assembly, the user can freely control the position and angle of the brewing faucet when making hand-brewed coffee. During the brewing process, the user can flexibly adjust the water outlet direction and water flow rate of the brewing faucet according to the distribution and extraction requirements of the coffee powder, so that the hot water evenly infiltrates the coffee powder and fully extracts the aroma and flavor of the coffee. One end of the pipe is connected to the brewing faucet, and the other end is connected to the heating assembly. This structural design enables hot water to be stably and continuously transported from the heating assembly to the brewing faucet, simulating the water flow state of traditional hand-brewed coffee. The stable supply of hot water ensures the consistency of water temperature during the brewing process, avoiding the influence of water temperature fluctuations on the coffee extraction effect. At the same time, the rational layout and diameter design of the pipes can control the pressure and flow of the water flow, making the water flow from the brewing faucet closer to the water flow characteristics of a traditional hand-brew kettle, allowing users to experience the production process and taste of professional hand-brew coffee at home. The detachable connection between the brewing faucet and the shell assembly, as well as the connection design between the pipe, the brewing faucet, and the heating assembly, ensures the stability of the connection while ensuring disassembly. During the operation of the coffee machine, even if the water pressure generated by the heating assembly is high, the brewing faucet and the pipe will not loosen or leak. This stable connection structure ensures that hot water can be safely and stably delivered from the heating assembly to the brewing faucet, avoiding safety hazards such as hot water leakage and burns caused by loose connections, thereby improving the safety and reliability of the coffee machine.

[0007] In one embodiment, the brewing faucet includes a faucet body and a valve body, and the valve body is arranged on the faucet body. The valve body has at least a first state and a second state. When the valve body is in the first state, the faucet body is blocked, and when the valve body is in the second state, the faucet body is open. By controlling the state of the valve body, the brewing faucet can simulate the brewing technique of a professional barista. During the brewing process, the user can imitate professional drip filling, circle filling and other methods, and use the opening and closing of the valve body to control the start and stop and size change of the water flow, so that the hot water and coffee powder are fully in contact and extracted evenly. This precise water flow control allows users to replicate the professional brewing effect of a coffee shop at home, improves the professionalism and fun of coffee making, and enhances the user experience. When the valve body is in the first state, the faucet body is blocked, which can effectively prevent the hot water in the heating component from accidentally flowing out when not in use.

[0008] One embodiment further includes a first control component for regulating the temperature or flow rate of the liquid entering the pour-over assembly from the heating component. The first control component precisely regulates the temperature of the liquid entering the pour-over assembly from the heating component, which is crucial for coffee extraction. Different types of coffee beans have different optimal extraction temperatures. Using the first control component, users can precisely adjust the water temperature to the appropriate range based on the characteristics of the coffee beans, ensuring that the hot water fully and appropriately extracts the coffee's flavor when it comes into contact with the coffee grounds, resulting in high-quality coffee with a rich, layered flavor. Alternatively, the first control component's ability to regulate the liquid flow rate allows users to better control the coffee extraction process. During the brewing process, a stable and appropriate flow rate helps the hot water evenly penetrate the coffee grounds, ensuring a more complete and uniform extraction. Precise flow control avoids under-extraction caused by excessive water flow or over-extraction caused by insufficient water flow, thereby improving the overall quality and taste of the coffee.

[0009] In one embodiment, a second control component is further included. One of the first and second control components is configured to control the temperature of the liquid entering the pour-over assembly from the heating component, while the other is configured to control the flow rate of the liquid entering the pour-over assembly from the heating component. By focusing on temperature and flow rate regulation, respectively, the first and second control components ensure precise regulation. For example, temperature regulation can precisely adjust the temperature of the water supplied from the heating component to the pour-over assembly, minimizing temperature errors and ensuring that coffee beans of varying roast levels are extracted at the optimal temperature. Similarly, flow rate regulation can precisely control the water flow rate, ensuring stable operation for both slow drip infusion and rapid continuous infusion. This provides stable and optimal water flow conditions for coffee extraction, thereby enhancing the professionalism and quality consistency of coffee brewing. The two control components work together to comprehensively optimize the coffee extraction process. In actual brewing, the water temperature is first adjusted to the appropriate range, and then the flow rate is precisely controlled based on factors such as the grind size and amount of coffee beans. This collaborative working mode can achieve refined parameter adjustment according to different coffee making needs, maximize the flavor potential of coffee beans, and produce high-quality coffee.

[0010] In one of the embodiments, a magnetic part is provided on one of the hand-injection assembly and the shell assembly, and an adsorption part is provided on the other of the hand-injection assembly and the shell assembly, and the magnetic part is magnetically matched with the adsorption part. The magnetic coordination of the magnetic part and the adsorption part makes it extremely simple to install the hand-injection assembly on the shell assembly. The user does not need to use any tools, but only needs to bring the hand-injection assembly close to the shell assembly, and the magnetic part and the adsorption part will automatically adsorb and accurately position under the action of the magnetic force, and the entire installation process can be completed in just a few seconds. For example, when hurriedly preparing coffee in the morning, the user can quickly install the hand-injection assembly in place and quickly start brewing coffee, which greatly saves time and improves the convenience of use. It is especially suitable for users with a fast pace of life and the pursuit of efficiency.

[0011] In one embodiment, the housing assembly includes a housing body and a retaining member. The retaining member is disposed on the housing body, and the hand-wash assembly is removably mounted on the retaining member. The retaining member disposed on the housing body provides a clear reference for the hand-wash assembly's installation position. When installing the hand-wash assembly, the user need not rely on experience or repeated adjustments; simply aligning the hand-wash assembly with the retaining member allows for quick identification, significantly reducing installation difficulty.

[0012] In one embodiment, the liquid supply assembly includes a pump assembly, one end of the pump assembly is connected to the heating assembly, and the other end of the pump assembly is used to communicate with an external liquid source.

[0013] In one embodiment, a fifth valve body and a third control assembly are further included. The third control assembly is disposed on the housing assembly. The heating assembly, the fifth valve body, and the hand-wash assembly are sequentially connected. The third control assembly is electrically connected to the fifth valve body. The fifth valve body can be opened or closed by the third control assembly through the configuration of the fifth valve body. When the fifth valve body is open, the heating assembly can be used to supply liquid to the hand-wash assembly.

[0014] In one embodiment, it further includes a first valve body, a second valve body and a third valve body, the first valve body is connected to the liquid supply component and the heating component respectively, the heating component is connected to the brewing system through the second valve body, and the heating component is connected to the hand-pouring component through the third valve body.

[0015] In one embodiment, the heating assembly includes a first boiler and a second boiler, and also includes a fourth valve body. The first valve body is connected to the liquid supply assembly and the first boiler respectively. The first boiler is connected to the brewing system through the second valve body. The first boiler is connected to the hand-pouring assembly through the third valve body. The first valve body, the second boiler, the fourth valve body and the steam pipe are connected in sequence.

[0016] In one embodiment, the invention further includes a fourth valve body and a steam pipe, wherein the heating component is in communication with the fourth valve body, and the fourth valve body is in communication with the steam pipe.

[0017] In one embodiment, the liquid supply assembly includes a water tank assembly and a first pump body, which are sequentially connected to the heating assembly. The water tank assembly, which serves as a water storage component, provides a stable liquid reserve for the coffee machine. Users only need to fill the water tank assembly once to meet the water needs for multiple coffee brewing sessions, eliminating the need for frequent refills. For family gatherings or office settings, when multiple cups of coffee need to be brewed consecutively, the ample water supply ensures the coffee brewing process is not interrupted due to water shortages, enhancing continuity and convenience. The first pump body precisely controls the water flow, steadily delivering water from the water tank assembly to the heating assembly. The first pump body can adjust the water flow rate and speed based on the coffee machine's operating program and user-configured parameters. For example, when making espresso, the first pump body delivers water to the heating assembly at a stable and appropriate flow rate, ensuring that the hot water is fully extracted from the coffee grounds in a short period of time. For pour-over coffee, however, the flow rate can be adjusted to a smaller and more uniform level, meeting the water flow requirements of different coffee brewing techniques and ensuring stability and consistency during the coffee brewing process.

[0018] In one embodiment, a flow meter is further included, and the water tank assembly, the flow meter, the first pump, and the heating assembly are sequentially connected. The flow meter accurately measures the water flow from the water tank assembly to the first pump and the heating assembly. The flow meter can promptly detect abnormal water flow. If problems such as pipe blockage or first pump failure cause abnormal water flow, the flow meter can feed abnormal data back to the coffee machine's control system, triggering an early warning.

[0019] In one embodiment, a safety valve is further included. The water tank assembly, the first pump body, the safety valve, and the heating assembly are sequentially connected, and the safety valve is connected to the water tank assembly. The safety valve is sequentially connected to the water tank assembly, the first pump body, and the heating assembly, enabling real-time monitoring of pressure changes within the liquid supply system. If the first pump body malfunctions or the heating assembly is heating, the pressure within the system may rise sharply due to poor water flow, steam accumulation, or other reasons. At this time, the safety valve automatically opens, releasing the excess pressure to the water tank assembly, preventing dangerous situations such as pipe rupture and hot water splashing.

[0020] In one embodiment, the heating assembly includes a first boiler and a second boiler, as well as a second pump and a steam valve. The water tank assembly, the first pump, the first boiler, and the brewing system are sequentially connected, while the water tank assembly, the second pump, the second boiler, and the steam valve are sequentially connected. The hand-pour assembly is connected to either the first boiler or the second boiler. The independent operation of the first and second boilers allows for simultaneous fulfillment of different coffee brewing processes. The first boiler is connected to the water tank assembly, the first pump, and the brewing system, specifically providing stable hot water for coffee extraction. The second boiler is connected to the water tank assembly via the second pump and is connected to the steam valve, specifically for steam generation to meet requirements for milk frothing and steam cleaning. Precisely matching different brewing processes: Different coffee brewing processes have varying requirements for water temperature, water volume, and steam volume. The first boiler precisely adjusts the water temperature and volume based on the brewing system's requirements, ensuring a stable water temperature during the coffee extraction process and fully extracting the coffee flavor. The second boiler can generate varying steam intensities on demand to meet diverse milk frothing requirements.

[0021] A second aspect of the present application discloses a coffee brewing method, which is applied to the above-mentioned coffee machine, comprising:

[0022] S. Start the liquid supply component to supply water to the heating component through the liquid supply component;

[0023] S. Supplying hot water to the brewing system through the heating component to perform first mode coffee brewing or supplying hot water to the hand-pour component through the heating component to perform second mode coffee brewing.

[0024] The coffee brewing method disclosed in the present application only requires simple operations to supply water to the heating component, without the need for complicated adjustments and settings. Users can quickly switch to the first mode and brew through the brewing system or the second mode and brew through the hand-brew component through simple operating instructions according to their own preferences or needs. This modular operation design is simple to operate, and even non-professionals can easily make different styles of coffee, meet diverse taste requirements, and enhance user experience. The two brewing modes S are optimized for different coffee making processes. In the first mode, the adaptive design of the heating component and the brewing system can provide hot water of appropriate temperature and flow according to the characteristics of the brewing system to achieve efficient extraction; in the second mode, the heating component supplies hot water to the hand-brew component to meet the requirements of hand-brew coffee for water flow stability and temperature accuracy. Whether it is making espresso or hand-brewed single-origin coffee, this brewing method can give full play to the performance advantages of each component to produce high-quality coffee drinks.

[0025] In one embodiment, the specific steps of supplying hot water to the hand brewing assembly through the heating assembly to brew coffee in the second mode are as follows:

[0026] heating the liquid inputted by the liquid supply component through the heating component;

[0027] The heating component is controlled by adjusting the first control component to adjust the heating temperature of the heating component to a preset temperature;

[0028] The flow rate of the liquid output by the heating component is controlled by adjusting the second control component so that the output flow rate of the liquid is a preset flow rate;

[0029] The brewing component is turned on to spray the liquid output of the preset temperature and preset flow rate onto the coffee powder for brewing.

[0030] By adjusting the first control component, the heating element is controlled to a preset temperature, precisely meeting the optimal extraction temperature requirements of different coffee beans. Coffee beans of different roast levels and varieties have different optimal extraction temperatures for their flavor components. The second control component controls the flow rate of the liquid output from the heating element to a preset rate, ensuring that the hot water is sprayed onto the coffee grounds at a stable and appropriate rate during the brewing process. A stable flow rate helps the hot water evenly penetrate the coffee grounds, ensuring a more complete and uniform extraction. If the flow rate is too high, the hot water may quickly pass through the coffee grounds, resulting in insufficient extraction and a weak coffee taste. If the flow rate is too low, the hot water may overextract, resulting in a bitter taste. An appropriate and stable flow rate, such as when making pour-over coffee, can be controlled to maintain a stable flow rate based on the amount and grind size of the coffee grounds, ensuring that every part of the coffee grounds is fully and consistently extracted, thereby improving the overall quality and taste consistency of the coffee. Adjusting the temperature and flow rate using the first and second control components is simple and convenient. Personalized brewing meets diverse needs: Preset temperature and flow rates provide users with highly customized brewing options. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] The following describes a coffee machine and a coffee brewing method according to some embodiments of the present invention with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figures 1 to 2 As shown, this embodiment discloses a coffee machine, comprising: a shell assembly 1, the shell assembly 1 is provided with a mounting cavity 101; a liquid supply assembly 2, the liquid supply assembly 2 is arranged on the shell assembly 1 and is at least partially located in the mounting cavity 101; a heating assembly, the heating assembly is arranged on the shell assembly 1 and is at least partially located in the mounting cavity 101, and the heating assembly is connected to the liquid supply assembly 2; a brewing system 3, the brewing system 3 is arranged on the shell assembly 1 and is connected to the heating assembly; and a hand brewing assembly 4, the hand brewing assembly 4 is detachably arranged on the shell assembly 1 and is connected to the heating assembly.

[0049] The coffee machine disclosed in the present application is connected in sequence through a liquid supply component 2, a heating component, and a brewing system 3, forming a complete and efficient coffee brewing process. The liquid supply component 2 is responsible for storing and transporting water, and sends water to the heating component. The heating component quickly heats the water to a suitable temperature and then transports it to the brewing system 3. In the brewing system 3, the hot water is fully in contact with and extracted from the coffee powder, thereby producing delicious coffee. This design ensures a stable supply of water flow and heat during the coffee making process, and can accurately control the time and temperature of coffee extraction. The hand-brew component 4 is detachably arranged on the housing component 1 and is connected to the heating component, providing users with a variety of coffee making options. Users can quickly make standard coffee drinks through the brewing system 3, or they can remove the hand-brew component 4, brew through the hand-brew component 4, and enjoy the fun of hand-brewed coffee. The hand-brew component 4 meets the personalized needs of different users for coffee making methods. For users who like a slow pace and pursue a layered coffee flavor, the hand-brew component 4 allows them to control factors such as water flow rate and brewing time according to their preferences, making unique hand-brew coffee, enriching the functions and usage scenarios of the coffee machine. Each component is arranged on the shell assembly 1 and partially located in the installation cavity 101, making the overall structure of the coffee machine compact. This compact layout design concentrates the various functional modules required for coffee making in a relatively small space. The setting of the installation cavity 101 provides a reasonable installation space for the liquid supply component 2, the heating component, etc., and effectively utilizes the internal space of the shell assembly 1. By partially placing these components in the installation cavity 101, it not only ensures the stability of the installation of the components, but also avoids the components being exposed to the outside and taking up too much space, making the overall appearance of the coffee machine more simple and beautiful.

[0050] like Figure 1 and Figure 2As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that the hand-pour assembly 4 includes a brewing tap 41 and a pipe 42. The brewing tap 41 is detachably mounted on the housing assembly 1. One end of the pipe 42 is connected to the brewing tap 41, and the other end is connected to the heating assembly. With the brewing tap 41 detachably mounted on the housing assembly 1, the user can freely control the position and angle of the brewing tap 41 when making hand-poured coffee. During the brewing process, the user can flexibly adjust the water flow direction and speed of the brewing tap 41 according to the distribution of the coffee powder and the extraction requirements, so that the hot water evenly penetrates the coffee powder and fully extracts the aroma and flavor of the coffee. One end of the pipe 42 is connected to the brewing tap 41, and the other end is connected to the heating assembly. This structural design ensures a stable and continuous flow of hot water from the heating assembly to the brewing tap 41, simulating the water flow of traditional hand-poured coffee. The stable hot water supply ensures consistent water temperature during the brewing process, preventing temperature fluctuations from affecting coffee extraction. At the same time, the reasonable layout and diameter design of the pipe 42 can control the pressure and flow of the water flow, so that the water flow out of the brewing tap 41 is closer to the water flow characteristics of a traditional hand-brewed kettle, allowing users to experience the production process and taste of professional hand-brewed coffee at home. The detachable connection between the brewing tap 41 and the shell assembly 1 and the connection design between the pipe 42, the brewing tap 41 and the heating assembly ensures the stability of the connection while ensuring detachability. During the operation of the coffee machine, even if the water flow pressure generated by the heating assembly is large, the brewing tap 41 and the pipe 42 will not loosen or leak. This stable connection structure ensures that hot water can be safely and stably transported from the heating assembly to the brewing tap 41, avoiding hot water leakage due to loose connection, causing safety hazards such as burns, and improving the safety and reliability of the coffee machine.

[0051] like Figure 1 and Figure 2As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: the brewing faucet 41 includes a faucet body 411 and a valve body 412. The valve body 412 is mounted on the faucet body 411 and has at least a first state and a second state. When the valve body 412 is in the first state, the faucet body 411 is blocked, and when the valve body 412 is in the second state, the faucet body 411 is open. By controlling the state of the valve body 412, the brewing faucet 41 can simulate the brewing techniques of a professional barista. During the brewing process, users can imitate professional drip and circular pouring techniques, using the opening and closing of the valve body 412 to control the start and stop and adjust the flow of water, ensuring sufficient contact between hot water and coffee grounds and uniform extraction. This precise water flow control allows users to replicate the professional brewing effect of a coffee shop at home, enhancing the professionalism and fun of coffee making and enhancing the user experience. When the valve body 412 is in the first state, the faucet body 411 is blocked, effectively preventing the hot water in the heating assembly from accidentally leaking when not in use.

[0052] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further comprises a first control assembly 5 for regulating the temperature or flow rate of the liquid entering the pour-over assembly 4 from the heating assembly. The first control assembly 5 allows precise adjustment of the temperature of the liquid entering the pour-over assembly 4, which is crucial for coffee extraction. Different types of coffee beans have different optimal extraction temperatures. Using the first control assembly 5, the user can precisely adjust the water temperature to the appropriate range based on the characteristics of the coffee beans, ensuring that the hot water fully and appropriately extracts the flavors from the coffee when it comes into contact with the coffee grounds, resulting in high-quality coffee with a rich, distinct flavor. Alternatively, the first control assembly 5's ability to regulate the liquid flow rate allows the user to better control the coffee extraction process. During the brewing process, a stable and appropriate flow rate helps the hot water evenly penetrate the coffee grounds, ensuring a more complete and uniform extraction. Precise flow rate control avoids issues such as under-extraction due to excessive water flow or over-extraction due to insufficient water flow, thereby improving the overall quality and taste of the coffee.

[0053] like Figure 1 and Figure 2As shown, in addition to the features of the above-mentioned embodiment, this embodiment further comprises a second control assembly 6. One of the first control assembly 5 and the second control assembly 6 is used to control and adjust the temperature of the liquid entering the pour-over assembly 4 from the heating assembly, and the other of the first control assembly 5 and the second control assembly 6 is used to adjust the flow rate of the liquid entering the pour-over assembly 4 from the heating assembly. By focusing on temperature and flow rate regulation, respectively, the first control assembly 5 and the second control assembly 6 ensure precise regulation. For example, temperature regulation can precisely adjust the temperature of the water delivered from the heating assembly to the pour-over assembly 4, minimizing temperature errors and ensuring that coffee beans of varying roast levels are extracted at the optimal temperature. Similarly, flow rate regulation can precisely control the water flow rate, ensuring stable implementation of both slow drip injection and rapid continuous injection, providing stable and appropriate water flow conditions for coffee extraction, thereby enhancing the professionalism and quality consistency of coffee production. The two control assemblies work together to comprehensively optimize the coffee extraction process. In actual brewing, the water temperature is first adjusted to the appropriate range, and then the flow rate is precisely controlled based on factors such as the grind size and amount of coffee beans. This collaborative working mode can achieve refined parameter adjustment according to different coffee making needs, maximize the flavor potential of coffee beans, and produce high-quality coffee.

[0054] In addition to the features of the above-mentioned embodiment, this embodiment further defines that: a magnetic part is provided on one of the hand-injection component 4 and the shell component 1, and an adsorption part is provided on the other of the hand-injection component 4 and the shell component 1, and the magnetic part and the adsorption part are magnetically matched. The magnetic combination of the magnetic part and the adsorption part makes it extremely simple to install the hand-injection component 4 on the shell component 1. The user does not need to use any tools, but only needs to bring the hand-injection component 4 close to the shell component 1, and the magnetic part and the adsorption part will automatically adsorb and accurately position under the action of the magnetic force, and the entire installation process can be completed in just a few seconds. For example, when hurriedly preparing coffee in the morning, the user can quickly install the hand-injection component 4 in place and quickly start brewing coffee, which greatly saves time and improves the convenience of use. It is especially suitable for users with a fast pace of life and the pursuit of efficiency.

[0055] like Figure 1 and Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that the housing assembly 1 includes a housing body 11 and a stopper 12. The stopper 12 is disposed on the housing body 11, and the handwash assembly 4 is removably mounted on the stopper 12. The stopper 12 disposed on the housing body 11 provides a clear reference for the installation position of the handwash assembly 4. When installing the handwash assembly 4, the user can quickly find the correct installation position by simply aligning the handwash assembly 4 with the stopper 12, without relying on experience or repeated adjustments, greatly reducing the difficulty of installation.

[0056] In addition to the features of the above embodiment, this embodiment further defines that: the liquid supply component 2 includes a pump body component, one end of the pump body component is connected to the heating component, and the other end of the pump body component is used to communicate with an external liquid source.

[0057] In addition to the features of the above-described embodiment, this embodiment further comprises: a fifth valve body and a third control assembly, the third control assembly being disposed on the housing assembly 1, the heating assembly, the fifth valve body, and the hand-wash assembly 4 being sequentially connected, and the third control assembly being electrically connected to the fifth valve body. The fifth valve body can be opened or closed by the third control assembly through the configuration of the fifth valve body, and when the fifth valve body is open, the heating assembly can supply liquid to the hand-wash assembly 4.

[0058] like Figure 3 As shown, in addition to the features of the above embodiment, this embodiment is further defined as follows: it also includes a first valve body 81, a second valve body 82 and a third valve body 83, the first valve body 81 is connected to the liquid supply component 2 and the heating component respectively, the heating component is connected to the brewing system 3 through the second valve body 82, and the heating component is connected to the hand-pouring component 4 through the third valve body 83.

[0059] like Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines: the heating assembly includes a first boiler 71 and a second boiler, and also includes a fourth valve body 84; the first valve body 81 is connected to the liquid supply assembly 2 and the first boiler 71 respectively; the first boiler 71 is connected to the brewing system 3 via the second valve body 82; the first boiler 71 is connected to the hand-pour assembly 4 via the third valve body 83; the first valve body 81, the second boiler, the fourth valve body 84 and the steam pipe are connected in sequence;

[0060] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment is further defined as including: a fourth valve body 84 and a steam pipe, the heating assembly is in communication with the fourth valve body 84, and the fourth valve body 84 is in communication with the steam pipe.

[0061] like Figure 3 As shown, in addition to the features of the above embodiment, this embodiment is further defined as follows: it also includes a waste water box 9, and the waste water box 9 is connected to the pump body assembly, the first valve body 81, and the second valve body 82 through pipelines.

[0062] like Figure 2As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the liquid supply assembly 2 includes a water tank assembly 21 and a first pump body, and the water tank assembly 21, the first pump body and the heating assembly are connected in sequence. The water tank assembly 21 is used as a component for storing water, providing a stable liquid reserve for the coffee machine. The user only needs to fill the water tank assembly 21 with water once to meet the water demand for multiple coffee making, avoiding the trouble of frequent water additions. In family gatherings or office scenarios, when multiple cups of coffee need to be made continuously, sufficient water reserves ensure that the coffee making process will not be interrupted due to water shortage, thereby improving the continuity and convenience of use. The setting of the first pump body can accurately control the water flow and stably deliver the water in the water tank assembly 21 to the heating assembly. The first pump body can adjust the size and speed of the water flow according to the working program of the coffee machine and the parameters set by the user. For example, when making espresso, the first pump body delivers water to the heating component at a stable and appropriate flow rate, ensuring that the hot water is fully extracted from the coffee powder in a short time; when making hand-brew coffee, the water flow can be adjusted to a smaller and more uniform one, meeting the water flow requirements of different coffee making processes and ensuring the stability and consistency of the coffee making process.

[0063] like Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further comprises: a flow meter, wherein the water tank assembly 21, the flow meter, the first pump body, and the heating assembly are sequentially connected. The flow meter accurately measures the water flow from the water tank assembly 21 to the first pump body and the heating assembly. The flow meter can promptly detect abnormal water flow. If problems such as pipe blockage or first pump failure cause abnormal water flow, the flow meter can feed abnormal data back to the coffee machine control system, triggering an early warning.

[0064] like Figure 2 As shown, in addition to the features of the above-described embodiment, this embodiment further defines: it also includes a safety valve, and the water tank assembly 21, the first pump body, the safety valve, and the heating assembly are sequentially connected, and the safety valve is connected to the water tank assembly 21. The safety valve is connected to the water tank assembly 21, the first pump body, and the heating assembly in sequence, allowing real-time monitoring of pressure changes within the liquid supply system. If the first pump body malfunctions or the heating assembly is heating, the pressure within the system may rise sharply due to factors such as poor water flow or steam accumulation. At this time, the safety valve automatically opens, releasing the excess pressure to the water tank assembly 21, preventing dangerous situations such as pipe rupture and hot water splashing.

[0065] In addition to the features of the above embodiment, this embodiment further defines: the heating assembly includes a first boiler and a second boiler, as well as a second pump and a steam valve; the water tank assembly, the first pump, the first boiler, and the brewing system 3 are sequentially connected; the water tank assembly, the second pump, the second boiler, and the steam valve are sequentially connected; and the hand-drip assembly 4 is connected to either the first boiler or the second boiler. The independent operation of the first and second boilers allows for simultaneous fulfillment of different coffee brewing processes. The first boiler is connected to the water tank assembly, the first pump, and the brewing system 3, specifically providing stable hot water for coffee extraction. The second boiler is connected to the water tank assembly via the second pump and is connected to the steam valve, specifically generating steam for functions such as milk frothing and steam cleaning. Precisely matching different brewing processes: Different coffee brewing processes have varying requirements for water temperature, water volume, and steam volume. The first boiler precisely adjusts the water temperature and volume according to the requirements of the brewing system 3, ensuring a stable water temperature during the coffee extraction process and fully extracting the coffee flavor. The second boiler can generate steam of varying intensities on demand to meet diverse milk frothing requirements.

[0066] Example 2

[0067] This embodiment discloses a coffee brewing method, which is applied to the above-mentioned coffee machine, comprising:

[0068] S1. Start the liquid supply component 2, supplying water to the heating component through the liquid supply component 2;

[0069] S2. Supply hot water to the brewing system 3 through the heating component to perform first mode coffee brewing or supply hot water to the hand brewing component 4 through the heating component to perform second mode coffee brewing.

[0070] The coffee brewing method disclosed in the present application only requires simple operations to supply water to the heating component, without the need for complicated adjustments and settings. Users can quickly switch to the first mode and brew through the brewing system 3 or the second mode and brew through the hand-brew component 4 through simple operating instructions according to their own preferences or needs. This modular operation design is simple to operate, and even non-professionals can easily make different styles of coffee, meet diverse taste requirements, and enhance user experience. The two brewing modes S2 are optimized for different coffee making processes. In the first mode, the adaptive design of the heating component and the brewing system 3 can provide hot water of appropriate temperature and flow according to the characteristics of the brewing system 3 to achieve efficient extraction; in the second mode, the heating component supplies hot water to the hand-brew component 4 to meet the requirements of hand-brew coffee for water flow stability and temperature accuracy. Whether making espresso or hand-brewed single-origin coffee, this brewing method can give full play to the performance advantages of each component to produce high-quality coffee drinks.

[0071] In addition to the features of the above embodiment, this embodiment further defines the following specific steps for supplying hot water to the hand brewing assembly 4 through the heating assembly to brew coffee in the second mode:

[0072] The liquid inputted by the liquid supply component 2 is heated by the heating component;

[0073] The heating component is controlled by adjusting the first control component 5 to adjust the heating temperature of the heating component to a preset temperature;

[0074] The flow rate of the liquid output by the heating component is controlled by adjusting the second control component 6 so that the output flow rate of the liquid is a preset flow rate;

[0075] The brewing component 4 is turned on to spray the liquid output of the preset temperature and preset flow rate onto the coffee powder for brewing.

[0076] By adjusting the first control component 5 to control the heating element, the heating temperature is adjusted to a preset temperature, precisely meeting the optimal extraction temperature requirements of different coffee beans. Coffee beans of different roast levels and varieties have different optimal extraction temperatures for their flavor compounds. The second control component 6 controls the flow rate of the liquid output from the heating element to a preset rate, ensuring that the hot water is sprayed onto the coffee grounds at a stable and appropriate rate during the brewing process. A stable flow rate helps the hot water evenly penetrate the coffee grounds, ensuring a more complete and uniform extraction. If the flow rate is too high, the hot water may quickly pass through the coffee grounds, resulting in insufficient extraction and a weak coffee taste. If the flow rate is too low, the hot water may overextract, creating a bitter taste. An appropriate and stable flow rate, such as when making pour-over coffee, can be controlled to maintain a stable flow rate based on the amount and grind size of the coffee grounds, ensuring that every part of the coffee grounds is fully and consistently extracted, thereby improving the overall quality and taste consistency of the coffee. Adjusting the temperature and flow rate using the first and second control components 5 and 6 is simple and convenient. Personalized brewing meets diverse needs: Preset temperature and flow rates provide users with highly personalized brewing options.
