Description

Technical Field

[0001] This utility model relates to the technical field of water heating accessories, and in particular to a concealed liquid heating plate structure with induction and a water heating device. Background Technology

[0002] Currently, there are various electric kettles on the market that use electric heating. These products can quickly heat drinking liquids and are cleaner and more convenient than heating with a stove. The core heating component is a heat-conducting plate, located at the bottom of the kettle's inner liner. It typically includes a metal base plate, such as a circular stainless steel heat-conducting plate, or the bottom or part of the bottom of the metal inner liner can serve as the metal base plate. The metal base plate receives heat from the heating element, such as a resistance heating element. To ensure even heating and reduce heat loss, many products use a heating plate, such as an aluminum plate, between the metal base plate and the heating element. Because aluminum has excellent thermal conductivity, it can quickly and evenly conduct the heat from the heating element to the metal base plate.

[0003] Existing electric kettles generally come with temperature or level sensors to measure temperature or level. Currently, most temperature or level sensors are installed inside the kettle in the following ways: the temperature sensor passes through a stainless steel heat-conducting plate into the kettle body and is fixed with a nut. This method is visible during use and provides relatively accurate temperature sensing, but it is aesthetically unappealing, makes cleaning the kettle difficult, and also carries the risk of leakage. Level sensors are mostly located on the inner wall of the kettle, and their disadvantages are similar to those of temperature sensors.

[0004] In view of this, the inventor has designed a concealed liquid heating plate structure with induction and a water boiling device, which leads to this invention. Utility Model Content

[0030] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0031] Please see Figures 1 to 5 This invention relates to a concealed liquid heating plate structure with induction, as an embodiment 1 of the present invention. It includes a heat-conducting plate 10, a fixing tube 20, a sensor 30, and wires 40. The fixing tube 20 is located at the bottom of the heat-conducting plate 10; the sensor 30 is located inside the fixing tube 20; the wires 40 are connected to the sensor 30; the sensor 30 and part of the wires 40 are secured within the fixing tube 20 using sealant 50; at least one fixing tube 20 is provided, and the number of sensors 30 is the same as the number of fixing tubes 20. Specifically, one end of the wire 40 is electrically connected to the sensor 30 and can be fixed by soldering or other methods. The fixing tube 20 is hollow inside to allow the sensor 30 to fit against the bottom of the heat-conducting plate 10. This heating plate structure achieves temperature or position measurement by setting a fixing tube 20 at the bottom of the heat-conducting plate 10 and placing the sensor 30 inside the fixing tube 20. The sensor 30 is located on the outside of the heating element, which is not only aesthetically pleasing and easy to clean, but also avoids problems such as water leakage.

[0032] Further configuration: The heat conduction plate 10 is made of metal, for example: the heating element is made of stainless steel.

[0033] Further configuration: The fixing pipe 20 is made of metal, for example: the fixing pipe 20 is made of any one of iron pipe, aluminum pipe, or stainless steel pipe.

[0034] Further configuration: The sealant 50 is made of a high-temperature resistant material, such as epoxy resin potting compound, mainly to fix or confine the sensor 30 inside the fixing tube 20, while ensuring that the sensing surface of the sensor 30 is in contact with the bottom of the heat conduction plate 10, and also to achieve a sealing effect, which can improve the service life of the sensor 30.

[0035] Please refer to the details. Figure 1 , 2The heating plate structure also includes a heating device 60 disposed below the heat-conducting plate 10. The heating device 60 includes a heating element 62 and a heat-spreading plate 61. The heat-spreading plate 61 is disposed above the heat-conducting plate 10, and the heating element 62 is disposed below the heat-spreading plate 61. The heat-spreading plate 61 has a first through hole 611 for avoiding the fixing tube 20. Further configured, the outer wall of the fixing tube 20 is fitted to the inner side of the first through hole 611, or a gap is formed between the outer wall of the fixing tube 20 and the inner wall of the first through hole 611. The width of the gap is 2-10 mm, and the gap is filled with a heat insulation element 70. When the sensor 30 is measuring temperature, the heat-spreading plate 61 can be used to prevent the sensor 30 from being affected by the measurement, thus improving the measurement accuracy. The heat insulation element 70 can be a high-temperature resistant rubber ring or a high-temperature resistant adhesive filler to prevent the heat-spreading plate 61 from affecting the material of the sensor 30.

[0036] The sensor 30 is a liquid level sensor, a temperature sensor, or a water quality sensor, etc., to realize functions such as temperature measurement, liquid level measurement, and water quality measurement, respectively. All of them use the ultrasonic measurement principle for measurement. Of course, two fixed tubes 20 can be set in this utility model, and liquid level sensor and temperature sensor are respectively set in the two fixed tubes 20 to realize the required measurement.

[0037] Several fixing posts 612 are also provided at the bottom of the heat spreader 61, and the fixing posts 612 are provided with internal threaded holes. The fixing posts 612 are provided to facilitate better configuration of the entire heating plate structure.

[0038] Please refer to the details. Figure 6 , 7 The heat-conducting plate 10 is also provided with a water inlet 11, and the heat-spreading plate 61 is also provided with a second through hole 613 to avoid the water inlet 11. The water inlet 11 enables the heating plate structure to have the function of water supply. Example 2

[0039] Please see Figures 1 to 7 This is a water heating device as an embodiment 2 of the present invention, including a heating base, which adopts the hidden liquid heating plate structure with induction in embodiment 1.

[0040] In summary, the heating plate structure of this utility model can realize functions such as temperature measurement, liquid level measurement, and water quality measurement by setting a fixed tube at the bottom of the heat conduction plate and placing the sensor inside the fixed tube. The sensor is located on the outside of the heat conduction plate, which is not only aesthetically pleasing but also easy to clean. At the same time, it can avoid problems such as water leakage. It can realize the liquid heating container without probes and without foreign parts.
