[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee machine. Background Technology

[0002] In current coffee machine technology, adjusting parameters such as brewing temperature and pre-infusion time typically requires complex on-screen operation. This not only increases the difficulty of use for users but also reduces the efficiency and convenience of the coffee brewing process. Furthermore, while some coffee machines offer temperature and pre-infusion time adjustments, these functions are usually integrated into the machine's electronic control system, requiring users to operate them via touchscreen or buttons. While this electronic control method allows for precise adjustments, in practice, the user experience may be negatively impacted by an unintuitive interface design or slow response. Utility Model Content

[0003] Therefore, it is necessary to provide a coffee machine that addresses the problem of overly cumbersome operation in adjusting parameters such as brewing temperature and pre-infusion time in traditional coffee machines.

[0004] A coffee machine includes: a frame having a mounting cavity; a first adjustment assembly disposed on the frame, at least a portion of which is located outside the mounting cavity; a second adjustment assembly disposed on the frame, at least a portion of which is located outside the mounting cavity; a coffee brewing assembly disposed on the frame; and a main control system disposed on the frame, wherein the first adjustment assembly, the coffee brewing assembly, and the second adjustment assembly are all electrically connected to the main control system; the first adjustment assembly is used to control a first operating parameter of the coffee brewing assembly, and the second adjustment assembly is used to control a second operating parameter of the coffee brewing assembly.

[0005] This application discloses a coffee machine that allows for flexible adjustment of brewing parameters by incorporating a first adjustment component and a second adjustment component. The first adjustment component controls a first operating parameter of the coffee brewing component, and the second adjustment component controls a second operating parameter. These parameters include coffee brewing temperature, extraction time, pre-infusion time, and milk frothing temperature. Both the first and second adjustment components are mounted on the frame and at least partially located outside the mounting cavity, allowing users to easily operate them, simplifying the operation process and improving the user experience. Different first and second adjustment components allow for control of different parameters of the coffee brewing component, further enhancing the ease of operation. The first and second adjustment components can be adjusted using knobs or similar methods, further improving the intuitiveness and convenience of operating the coffee machine.

[0006] In one embodiment, the first operating parameter is brewing temperature or extraction time, and the second operating parameter is pre-infusion time or milk foam temperature. By explicitly defining the first operating parameter as brewing temperature or extraction time and the second operating parameter as pre-infusion time or milk foam temperature, the coffee machine's adjustment function becomes more practical. Since the first and second adjustment components are used to control the first and second operating parameters respectively, users can set the desired brewing temperature, extraction time, pre-infusion time, milk foam temperature, and other parameters by adjusting the external first and second adjustment components, improving operational efficiency. Furthermore, users can freely combine these parameters according to their preferences, thereby achieving more personalized coffee customization.

[0007] In one embodiment, a third adjustment component is further included. This third adjustment component is mounted on the frame, with at least a portion located outside the mounting cavity. The third adjustment component is electrically connected to the main control system and is used to control a third operating parameter of the coffee brewing component. By setting the third adjustment component to control the third operating parameter of the coffee brewing component, different parameters of the coffee brewing component can be controlled, thereby further expanding the functionality of the coffee machine. The combination of the first, second, and third adjustment components allows users to adjust different parameter combinations according to their preferences and needs, achieving more comprehensive personalization. The third adjustment component is mounted on the frame and at least a portion is located outside the mounting cavity. Like the first and second adjustment components, users can easily operate this adjustment component, improving the convenience of setting coffee machine parameters.

[0008] In one embodiment, a fourth adjustment component is also included. This fourth adjustment component is mounted on the frame, with at least a portion located outside the mounting cavity. It is electrically connected to the main control system and is used to control a fourth operating parameter of the coffee brewing component. This fourth operating parameter is one of brewing temperature, extraction time, pre-infusion time, and milk frothing temperature. By providing the fourth adjustment component, the coffee machine has four independent adjustment components to control four different operating parameters of the coffee brewing component. The design of the fourth adjustment component being mounted on the frame and at least partially located outside the mounting cavity allows users to set the coffee machine's operating parameters simply by adjusting the fourth adjustment component, without needing to use a screen or other operating methods, further improving the ease of operation. The fourth operating parameter is one of brewing temperature, extraction time, pre-infusion time, and milk frothing temperature. This means that users can choose one parameter to adjust according to their needs. The combination of the four adjustment components allows users to freely combine different parameters according to their preferences, thereby achieving more personalized coffee customization.

[0009] In one embodiment, the first operating parameter is one of brewing temperature, extraction time, pre-soaking time, and milk foam temperature;

[0010] In one embodiment, the second operating parameter is one of brewing temperature, extraction time, pre-soaking time, and milk foam temperature;

[0011] In one embodiment, the third operating parameter is one of brewing temperature, extraction time, pre-soaking time, and milk foam temperature.

[0012] In one embodiment, the coffee brewing assembly includes a boiler assembly, a brewing head, and a steam device. The boiler assembly, brewing head, and steam device are mounted on the frame and electrically connected to the main control system. The water outlet of the boiler assembly is connected to the water inlet of the brewing head. By incorporating the boiler assembly, brewing head, and steam device, the coffee machine can perform functions such as hot water supply, coffee extraction, and milk frothing. The connection between the water outlet of the boiler assembly and the water inlet of the brewing head ensures that hot water reaches the brewing head promptly and effectively, thereby improving the efficiency of coffee brewing. The electrical connection between the boiler assembly and the steam device allows the main control system to control the heating of the boiler assembly and the steam generation of the steam device according to user settings, thus achieving precise control of the coffee brewing process.

[0013] In one embodiment, a temperature sensor is also included, which is disposed on the boiler assembly and electrically connected to the main control system. The temperature sensor is used to detect the water temperature within the boiler assembly. By installing a temperature sensor on the boiler assembly, the water temperature within the boiler assembly can be monitored in real time, enabling the main control system to precisely control the boiler assembly based on the actual water temperature, ensuring that the outlet water temperature is always maintained within the set ideal range. The main control system can automatically adjust according to the data from the temperature sensor, making operation simpler and improving the intelligence of the control structure.

[0014] In one embodiment, the first adjustment assembly includes a first knob assembly and a first control element. The first knob assembly is mounted on the frame, with a portion extending into the mounting cavity. The first control element is mounted on the first knob assembly and located within the mounting cavity. The first knob assembly is connected to the first control element, and the first control element is electrically connected to the main control system. By mounting the first knob assembly on the frame, this design allows users to conveniently and directly adjust the coffee machine's operating parameters via the first knob assembly, greatly improving operational convenience. The first knob assembly is connected to the first control element, which is electrically connected to the main control system. The first adjustment assembly is used to control the first operating parameter of the coffee brewing assembly. Therefore, users can set the first operating parameter by adjusting the first knob assembly. The first operating parameter can be any one of brewing temperature, extraction time, pre-infusion time, and milk frothing temperature. The design of the first knob assembly allows users to precisely and quickly adjust the coffee-making operating parameters by rotating the first knob assembly, improving operational efficiency.

[0015] In one embodiment, the second adjustment assembly includes a second knob assembly and a second control element. The second knob assembly is mounted on the frame, with a portion extending into the mounting cavity. The second control element is mounted on the second knob assembly and connected to it. The second control element is electrically connected to the main control system. By externally mounting the second knob assembly on the frame, connecting it to the second control element, and electrically connecting the second control element to the main control system, and by using the second adjustment assembly to control the second operating parameters of the coffee brewing assembly, the user can directly set the second operating parameters for coffee brewing by rotating the second knob assembly. The second operating parameter can be any one of brewing temperature, extraction time, pre-infusion time, and milk frothing temperature. The external design of the second knob assembly allows the user to quickly and conveniently set the second operating parameters for coffee brewing by rotating the second knob assembly, making the operation process convenient and fast.

[0016] In one embodiment, the frame includes a support body, a first side plate, and a second side plate. The first side plate is disposed on the support body, and the second side plate is disposed on the support body. The second side plate is located on the side of the support body away from the first side plate. The first side plate and the second side plate are arranged opposite to each other, and the support body, the first side plate, and the second side plate cooperate to form the mounting cavity. A first adjustment component is disposed on the first side plate, and a second adjustment component is disposed on the second side plate. By disposing the first adjustment component on the first side plate and having a portion of the first adjustment component protrude outside the mounting cavity, this layout makes adjusting the coffee machine's operating parameters more convenient. Users can directly and precisely adjust the first operating parameters of the coffee brewing component by adjusting the portion of the first adjustment component protruding outside the mounting cavity to meet different coffee-making needs. A second adjustment component is disposed on the second side plate, with a portion of the second adjustment component protruding outside the mounting cavity. This design also makes setting the second operating parameters of the coffee brewing component convenient. Users can easily adjust the second operating parameters of the coffee brewing component by using the portion of the second adjustment component protruding outside the mounting cavity. Since the second side plate is located on the side of the support body away from the first side plate, this design also helps to avoid mutual interference during operation, making the adjustment more precise. With proper layout and configuration, it is possible to independently adjust working parameters such as pre-soaking time, brewing temperature, extraction time, and milk foam temperature, thereby improving the flexibility and convenience of coffee making.

[0017] In one embodiment, a water tank assembly is further included, which is disposed on the support body and located within the mounting cavity. The frame also includes a water tank cover plate, which covers the water tank assembly and the support body. The water tank cover plate and the water tank assembly cooperate to form a cold water storage chamber, which communicates with the water storage chamber. This design, where the water tank cover plate and the water tank assembly form a cold water storage chamber, allows for the separate storage and supply of cold water. The communication between the cold water storage chamber and the water storage chamber enables the water tank assembly to continuously supply water to the boiler assembly. The design of the water tank cover plate being detachably mounted above the water tank assembly allows for easier operation during water addition and maintenance. Attached Figure Description
