[0002] In traditional coffee machine brewing components, the brewing head's temperature drops after prolonged periods of inactivity due to changes in ambient temperature. This drop is particularly noticeable in colder environments, significantly cooling the hot water and directly impacting brewing quality. When the machine restarts and begins heating water, the brewing head's low temperature causes it to absorb heat as the hot water passes through. This heat absorption not only lowers the water temperature but can also result in excessively cold water, leading to suboptimal brewing. Especially in the delicate coffee brewing process, water temperature is crucial for extraction; excessively low temperatures result in weak, unpleasant-tasting coffee, potentially affecting the consistency of its quality and flavor. Furthermore, there are limitations in maintaining brewing head temperature. Users cannot effectively maintain the temperature after extended periods of inactivity, leading to inconsistent water temperatures each time the machine is used, inconsistent brewing quality, and a poor user experience.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings. A coffee machine with a preheating function includes a frame 1, a heating element mounted on the top of the frame 1, a brewing component 3 connected to the heating element via a conduit, hot water being heated by the heating element and delivered to the brewing component 3, a heat-conducting plate 4 disposed between the heating element and the brewing component 3, one end of the heat-conducting plate 4 being connected to the heating element, and the other end of the heat-conducting plate 4 being connected to the brewing component 3, the heat generated by the heating element being transferred to the brewing component 3 through the heat-conducting plate 4 to preheat and keep the brewing component 3 warm.

[0021] The heating component includes a heating pot 2 and a heating element built into the heating pot 2. The heating element is used to heat water. The heat-conducting plate 4 is attached to the bottom of the heating pot 2 to transfer heat to the brewing component 3 through heat conduction.

[0022] The heating pot 2 has a recessed mounting hole 21 in the middle, and the frame 1 has a protruding mounting post 11 on the top. The mounting post 11 is inserted into the mounting hole 21 to install the heating pot 2 on the frame 1.

[0023] The heat-conducting plate 4 has a through-hole groove 41 on one side, and the groove 41 is open on one side; the mounting post 11 passes through the open and is installed in the groove 41, clamping the heat-conducting plate 4 between the heating pot 2 and the frame 1.

[0024] The other side of the clamping groove 41 is bent and protruded to provide a limiting platform 42. The bottom of the heating pot 2 is provided with a limiting hole 22. The limiting platform 42 is installed in the limiting hole 22 to limit the lateral displacement of the heat-conducting plate 4.

[0025] A connection hole 43 is provided through the other side of the heat-conducting plate 4, and the brewing component 3 is fitted into the connection hole 43; a number of locking holes 44 are provided through the outer periphery of the connection hole 43, and the locking screw passes through the locking hole 44 to connect with the brewing component 3, thereby fixing the heat-conducting plate 4 in the brewing component 3.

[0026] Working principle: In this design, a heat-conducting plate is placed between the heating element and the brewing element. One end of the heat-conducting plate is connected to the heating element, and the other end is connected to the brewing element. When the coffee machine starts working, the heat generated by the heating element is transferred to the heat-conducting plate, and then further transferred to the brewing element, thus preheating and maintaining the temperature of the brewing element. This avoids the problem of the brewing head cooling down when not in use for extended periods in traditional coffee machines. In this way, even if the user does not use the coffee machine for a long time, the temperature of the brewing element can be maintained within a suitable range, improving the stability of the water temperature for each brew.

[0027] The heating element comprises a heating pot and a heating element built into it. The heating element heats the water, and the heat from the hot water is transferred to the entire heating pot. It should be noted that the heat-conducting plate is attached to the bottom of the heating pot, making large-area contact with it to more effectively absorb external heat and further transfer this heat to the brewing component, improving heat transfer efficiency and effectively preheating and maintaining the temperature of the brewing component.

[0028] Furthermore, the heat is distributed more evenly, ensuring a stable water temperature during brewing, which in turn ensures the extraction of coffee and avoids affecting the extraction and taste of coffee due to excessively low water temperature.

[0029] By using a preheating brewing unit, the water temperature is ensured to remain within the ideal range for each brew, avoiding changes in coffee flavor caused by excessively low or high temperatures. This guarantees the quality and consistency of each brew, ensuring a stable coffee taste and enhancing flavor concentration. Users can quickly enjoy coffee at the perfect temperature without waiting for excessive preheating time, improving ease of use and brewing results. It is especially suitable for mornings or busy workdays, enhancing the overall user experience of the coffee machine.

[0030] In the connection between the heating pot and the frame described above, a mounting hole is recessed in the middle of the heating pot, and a mounting post protrudes from the top of the frame. By inserting the mounting post into the mounting hole, the heating pot is fixed to the frame. The mounting post ensures that the heating pot is always firmly connected and installed. The hole-post connection ensures that the heating pot will not shift or loosen during use, guaranteeing the stability and reliability of the heating pot. The connection structure is simple, and the heating pot can be easily installed and disassembled, with high efficiency and convenient maintenance for users.

[0031] In the aforementioned installation and connection of the heat-conducting plate, a through-groove is formed on one side of the heat-conducting plate, with one side of the groove open. The aforementioned mounting post passes through this open end and is clamped in the groove, holding the heat-conducting plate between the heating element and the frame. A connection hole is formed on the other side of the heat-conducting plate, through which the brewing component is fitted. A locking screw passes through a locking hole on the outer periphery of the connection hole and locks the component with the heat-conducting plate. This ensures effective heat transfer between the heating element and the brewing component. The connection and installation structure of the heat-conducting plate is simple, avoiding complex and cumbersome operations, making overall assembly more convenient and quick, reducing the complexity of disassembly and maintenance of the heat-conducting plate, and improving user convenience.

[0032] To further enhance the connection strength of the heat-conducting plate, a limiting platform is provided on the bent protrusion on the other side of the clamping groove. Correspondingly, a limiting hole is provided at the bottom of the heating pot. When the mounting hole aligns with the mounting post, the limiting platform is installed in the limiting hole, restricting the lateral displacement of the heat-conducting plate, ensuring the stability of the heat-conducting plate in the horizontal direction, preventing its movement during use, ensuring stable heat transfer, and improving the overall stability of the coffee machine.

[0033] This coffee machine features a heat-conducting plate that transfers heat from the heating element to the brewing element, preheating and maintaining its temperature. Its simple structure reduces manufacturing costs and maintenance complexity compared to the complex temperature control designs of traditional coffee machines, offering a simple and reliable solution. By concentrating the heat dissipated from the heating element, the brewing element is preheated, minimizing energy loss during the heating process and contributing to energy efficiency. Furthermore, the more stable temperature eliminates the need for frequent high-temperature reheating, further reducing energy consumption and making it more environmentally friendly. Therefore, it is suitable for widespread use.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
