Description

Technical Field

[0001] This utility model belongs to the technical field of coffee equipment, and specifically relates to an electromagnetic pour-over coffee kettle with precise temperature control. Background Technology

[0002] As the core tool for making premium pour-over coffee, the performance of the pour-over kettle directly affects the controllability of coffee extraction and flavor expression. Traditional pour-over kettles consist of a kettle body and a heating element. The heating element is built into the bottom of the kettle body, and the heating element connects to a recessed area on the bottom of the kettle body via a raised socket for power supply and heating. However, this structure has significant drawbacks: the heating element method results in inaccurate temperature control and large temperature fluctuations, failing to meet the stringent temperature requirements for coffee extraction, thus affecting the purity and flavor profile of the coffee; the kettle body needs precise alignment with the raised heating element, requiring users to adjust its position, which is inconvenient and inefficient; when the kettle body is removed, heating stops, but the residual heat of the heating element remains, making real-time monitoring of the kettle's internal temperature impossible, causing problems for coffee enthusiasts, especially professional competitors. Precise temperature control, including accuracy, stability, response speed, and the accuracy of the water temperature output, is a key indicator that distinguishes pour-over kettles from ordinary kettles, but existing products generally lack sufficient temperature control capabilities, and the claimed high-precision temperature control is difficult to achieve in practical applications.

[0003] Therefore, existing technologies need to be improved and developed. Utility Model Content

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a precise temperature-controlled electromagnetic coffee pour-over kettle, comprising a temperature-controlled kettle 1 and a temperature-controlled induction cooker 2; the temperature-controlled kettle 1 is positioned above the temperature-controlled induction cooker 2.

[0031] The temperature-controlled kettle 1 includes a kettle body 3, a kettle lid 4, a base 5, a spout 6, and a handle 7; the kettle body 3 is equipped with a temperature control device 8 and a sensor assembly 9; the spout 6 is equipped with a water outlet temperature sensor 10; the kettle body 3 is equipped with a temperature indicator 11, which can indicate the temperature measurement result of the water outlet temperature sensor 10; the temperature control device 8 is equipped with a control chip and a wireless transmission module; the sensor assembly 9, the water outlet temperature sensor 10, the temperature indicator 11, and the wireless transmission module are all electrically connected to the control chip; the control chip is used to send heating start and stop commands to the temperature-controlled induction cooker 2 through the wireless transmission module.

[0032] In practical applications, the temperature-controlled kettle 1 is placed on the temperature-controlled induction cooker 2. After the induction cooker 2 is activated, it generates an alternating magnetic field, inducing eddy currents in the base 5 to generate heat, which is then transferred to the water inside the kettle body 3. The sensor assembly 9 monitors the water temperature changes inside the kettle, and the data is transmitted to the temperature control device 8 in real time. The control chip of the temperature control device 8 analyzes the temperature data and transmits control signals to the temperature-controlled induction cooker 2 via a wireless transmission module. The temperature-controlled induction cooker 2 adjusts its output power; for example, it increases the current output when the detected temperature is lower than the set value and decreases the power when it is higher than the set value. The temperature indicator 11 continuously indicates the current water temperature, and can still provide a temperature reading even if the kettle body 3 is moved away from the temperature-controlled induction cooker 2. The spout temperature sensor 10 detects the actual temperature of the water flow at the spout. When water flow is detected at the spout, the temperature indicator 11 prioritizes indicating this temperature. When no water flow is detected at the spout, the temperature indicator 11 prioritizes indicating the water temperature inside the kettle monitored by the sensor assembly 9.

[0033] The thermostat kettle 1 has its internal casing and base made of iron or alloy steel, metals capable of electromagnetic induction heating. The inner side of the kettle 1 is insulated from the temperature control device 8 and the temperature indicator device 11 using ceramic insulation or a vacuum insulation layer. The outlet temperature sensor 10 can be a waterproof probe. The temperature indicator device 11 can be a display screen and / or a voice broadcast system. The display screen shows the temperature, and the voice broadcast system provides temperature announcements (such as reading the temperature measurement results from the outlet temperature sensor 10 or temperature sensor assembly 9) and warnings (an alert will be issued when the temperature is below a preset threshold). The wireless transmission module can achieve wireless communication via Bluetooth, WIFI, or other wireless communication methods. The connection circuit of the thermostat kettle 1 (i.e., the communication circuit of the temperature control device 8) is located in the kettle body 3 and is isolated from the inner side of the kettle body 3 by a ceramic insulation plate or a vacuum insulation layer.

[0034] This application provides a precision temperature-controlled electromagnetic coffee pour-over kettle. By placing a water outlet temperature sensor in the spout of the kettle, the kettle can directly detect the water temperature at the outlet, ensuring a fast and accurate temperature response. The kettle also controls the temperature-controlled induction cooker via a wireless transmission module, thereby improving the accuracy and stability of temperature control.

[0035] Specifically, such as Figure 3 As shown, the temperature-controlled induction cooker 2 includes a housing 12 and a control module 13, an electromagnetic coil 14, and a heat dissipation device 15 disposed inside the housing 12; the electromagnetic coil 14 and the heat dissipation device 15 are both electrically connected to the control module 13; the control module 13 is communicatively connected to a wireless transmission module.

[0036] In practical applications, when the temperature-controlled induction cooker 2 is started, the electromagnetic coil 14 generates an alternating magnetic field, inducing eddy currents in the kettle base 5 to generate heat. This heat is transferred to the water inside the kettle body 3. The sensor assembly 9 monitors the water temperature changes inside the kettle, and the data is transmitted to the temperature control device 8 in real time. The control chip of the temperature control device 8 analyzes the temperature data and transmits control signals to the control module 13 via a wireless transmission module to dynamically adjust the power of the electromagnetic coil 14, thereby regulating the temperature changes of the water inside the kettle body 3. The heat dissipation device 15 maintains the temperature stability of the control module 13.

[0037] Specifically, such as Figure 1 As shown, the upper surface of the outer shell 12 is provided with a base surface 16 and a convex surface 17 that is higher than the base surface. The convex surface 17 is located directly above the electromagnetic coil 14, and the temperature-controlled induction cooker 2 contacts the temperature-controlled kettle 1 through the convex surface 17.

[0038] In practical applications, when the temperature-controlled kettle 1 is placed on the temperature-controlled induction cooker 2, simply placing the base 5 on the convex surface 17 eliminates alignment deviations, thus achieving "blind placement." When the temperature-controlled induction cooker 2 is operating, the temperature-controlled kettle 1 is heated by the electromagnetic coil below the convex surface 17.

[0039] Among them, the convex surface 17 material can be set as glass plate, black crystal panel, ceramic panel or black crystal panel, all of which have the advantages of high temperature resistance and easy cleaning, and are suitable for high temperature heating scenarios.

[0040] Preferably, the bottom of the housing 12 may be provided with multiple support feet to maintain balance.

[0041] In some alternative embodiments, the housing 12 can be divided into an upper housing and a lower housing for easy assembly and disassembly. The upper housing is the upper part of the housing 12, and a base surface 16 and a convex surface 17 above the base surface are disposed on the upper surface of the upper housing.

[0042] Specifically, such as Figure 2 As shown, the sensor assembly 9 is equipped with multiple temperature sensors; the multiple temperature sensors are arranged at equal intervals along the vertical direction on the inner side of the kettle body 3; the temperature indicator device 11 is also used to indicate the temperature measurement results of the sensor assembly 9.

[0043] In practical applications, the sensor assembly 9 is equipped with multiple temperature sensors, which are installed at equal intervals along the vertical direction inside the kettle body 3. During the heating process, temperature data from multiple points are simultaneously collected and transmitted to the temperature control device 8. The control chip of the temperature control device 8 calculates the water temperature inside the kettle and transmits the average temperature to the temperature indicator device 11. When no water flow is detected at the outlet, the temperature indicator device 11 displays the temperature and / or provides a voice announcement indicating the water temperature monitored by the sensor assembly 9. Thus, the average water temperature or overall water temperature trend is calculated, reducing measurement deviations caused by localized heat convection or cooling, and providing a reliable basis for precise temperature control.

[0044] In this process, the temperature data from multiple temperature sensors in the sensor assembly 9 are transmitted to the control chip of the temperature control device 8 to calculate the water temperature A inside the kettle. The formula for calculating A is: A = Where A is the water temperature inside the kettle, and n represents the number of temperature sensors. T is the weighted temperature coefficient of the i-th temperature sensor. i It is the water temperature measured by the i-th temperature sensor.

[0045] Specifically, the temperature control device 8 is also equipped with a battery; the battery is electrically connected to the control chip.

[0046] In practical applications, the temperature-controlled kettle 1 is equipped with two power supply methods, one of which is battery power. A battery is installed in the temperature control device 8, which is electrically connected to the control chip and provides an independent power supply. When the temperature-controlled kettle 1 is disconnected from the temperature-controlled induction cooker 2, the battery maintains the power supply to the temperature control device 8 to ensure continuous temperature monitoring.

[0047] In some alternative embodiments, the battery and wireless transmission module can be housed in the handle 7, thereby improving the space utilization of the temperature-controlled kettle 1 (the handle 7 becomes thicker and the kettle body 3 becomes thinner).

[0048] Specifically, a charging port is provided on the outer side of the base 5; the charging port is electrically connected to the battery.

[0049] In practical applications, when the temperature-controlled kettle 1 is powered by battery, a charging port is provided on the outside of the base 5 for direct connection to an external power source, thereby simplifying the charging operation and avoiding the need for disassembly. The charging port is electrically connected to the battery to ensure efficient power transfer to the battery, further maintaining the stable operation of the kettle's internal sensors, display function, and temperature control function. The charging port can be implemented using a Type-C interface or a micro interface.

[0050] When using battery power, the base 5 can be set as a single metal layer, and the charging port can be located at the bottom of the outer side of the kettle body 3.

[0051] Specifically, a mutual inductance coil is installed inside the base 5; the mutual inductance coil is electrically connected to the control chip;

[0052] The mutual inductance coil is used to power the temperature-controlled kettle.

[0053] In practical applications, the temperature-controlled kettle 1 is equipped with two power supply methods, the other being a mutual inductance coil power supply. When the temperature-controlled kettle 1 is placed on the convex surface 17 of the temperature-controlled induction cooker 2, the mutual inductance coil inside the base 5 interacts with the electromagnetic coil 14 of the temperature-controlled induction cooker 2 through electromagnetic induction, thereby causing the mutual inductance coil to generate voltage and current, which is used to power the control chip, realizing wireless power supply. This avoids the precise alignment operation required by physical sockets when using battery power supply.

[0054] When using mutual inductance coil power supply, the charging port location can be removed and the battery placement can be cancelled.

[0055] In some alternative embodiments, the temperature-controlled kettle 1 can also use a mutual inductance coil charging method, with a battery installed inside the kettle body 3 or inside the handle, and a mutual inductance coil installed inside the base 5. The mutual inductance coil is electrically connected to the battery, so that the battery can be wirelessly charged through the mutual inductance coil.

[0056] Alternatively, the temperature-controlled kettle 1 can also use a charging method of mutual inductance coil + charging port. A battery is set inside the kettle body 3 or inside the handle, and a mutual inductance coil and a charging port are set inside and on the side of the base 5 respectively. The mutual inductance coil and the charging port are electrically connected to the battery, so that the battery can achieve dual charging methods of wireless charging and wired charging through the mutual inductance coil and the charging port.

[0057] Specifically, such as Figure 4 As shown, Figure 4 This is a circuit diagram of a temperature-controlled induction cooker, where a is the power supply, L is the inductor, C is the capacitor, and R is the resistor. The control module 13 includes a main control circuit board 18 and a control board 19 that are electrically connected; the main control circuit board 18 is provided with an electrically connected bridge rectifier 20 and a power interface; the control board 19 is provided with a wireless receiving circuit 21, an MCU processor 22, and a drive circuit 23.

[0058] In practical applications, the control module 13 improves the accuracy and responsiveness of temperature control through modular design and collaborative division of labor. The control module 13 includes a main control circuit board 18 and a control board 19 electrically connected. The main control circuit board 18 handles power supply, with a power interface connecting to the power source to provide uninterrupted power input to the temperature-controlled induction cooker 2. A bridge rectifier 20 converts AC power into stable DC power, providing a clean power foundation for the temperature-controlled induction cooker 2. The control board 19 handles signal control. A wireless receiving circuit 21 communicates with the wireless transmitting module to receive temperature data or control signals (heating on / off commands) transmitted by the wireless transmitting module. The MCU processor 22 executes algorithms to calculate and adjust heating parameters, and the drive circuit 23 converts signals to drive the electromagnetic coil. This discrete architecture reduces circuit interference and ensures stable and reliable temperature control.

[0059] Among them, the driving circuit 23 can be designed as a SiC MOSFET, which utilizes its high switching frequency characteristics to optimize the current driving process of the electromagnetic coil, reduce energy loss and operation delay, thereby achieving rapid adjustment and stable control of water temperature during coffee extraction.

[0060] Specifically, the heat dissipation device 15 includes a heat sink 24 and a fan 25.

[0061] In specific applications, the heat dissipation device 15 includes a heat sink 24 and a fan 25. The heat sink 24 absorbs the heat generated by components such as the control module 13 and the electromagnetic coil 14. The fan 25 accelerates the dissipation of heat from the surface of the heat sink 24 by forcing airflow. The two work together to prevent temperature runaway caused by heat accumulation, thereby supporting precise temperature control.

[0062] Specifically, the outer casing 12 is also provided with a plurality of heat dissipation holes 26; the plurality of heat dissipation holes 26 are respectively disposed between the side surface and the bottom surface of the outer casing 12.

[0063] In practical applications, multiple heat dissipation holes 26 are respectively arranged between the side and bottom surfaces of the outer casing 12. The heat dissipation holes 26 promote air convection to achieve auxiliary heat dissipation by allowing hot air to escape. The heat dissipation device 15 is directly opposite some of the heat dissipation holes 26. The fan 25 accelerates the dissipation of heat from the surface of the radiator 24 by forcing airflow, and the dissipated heat is discharged from the temperature-controlled induction cooker 2 through the heat dissipation holes 26.

[0064] In some optional embodiments, when the outer casing 12 is configured as an upper outer casing and a lower outer casing, a plurality of heat dissipation holes 26 are provided in the lower outer casing, and the portion between the side and bottom of the lower outer casing is configured as a plurality of heat dissipation holes 26 to dissipate the heat generated inside the temperature-controlled induction cooker 2.

[0065] This technical solution, by placing a water outlet temperature sensor in the spout of the thermostat kettle, can directly detect the water temperature at the outlet, ensuring a fast and accurate response to the actual temperature. The temperature is then controlled by a wireless transmission module to heat the kettle, improving the accuracy and stability of temperature control in the electromagnetic pour-over coffee maker.
