背景技术Background technique
目前市场上的电陶炉一般包括外壳、机芯和加热面板，机芯包括发热盘和机芯底座，机芯底座包括上盖、基壳、下盖、散热风扇和电路板等结构，加热面板设于发热盘的上侧，工作时，发热盘内的发热丝产生的热量加热面板，加热面板对放置的物品进行加热。电陶炉用途广，除了具有烧水、煎炒、烧烤、火锅、爆炒、热奶、煲汤、慢炖、预约等强大功能外，还能配套烤盘，烤网，进行铁板烧，烧烤等休闲娱乐，因此深受广大消费者的青睐。Electric ceramic stoves currently on the market generally include a casing, a core and a heating panel. The core includes a heating plate and a base of the core. It is arranged on the upper side of the heating plate. When working, the heat generated by the heating wire in the heating plate heats the panel, and the heating panel heats the placed items. The electric ceramic stove has a wide range of uses. In addition to the powerful functions of boiling water, frying, grilling, hot pot, stir-frying, heating milk, soup, slow stewing, and reservations, it can also be equipped with baking pans, grilling nets, teppanyaki, and barbecue. And other leisure and entertainment, so by the majority of consumers of all ages.
电路板上设有功率控制元件，用于调节发热盘的发热功率，工作时功率控制元件产生热量通过其自身的散热部进行散热，保证功率控制元件的正常工作。但是，在实际使用时，使用者对功率控制元件的调节范围较大，导致功率控制元件的温度急剧升高，仅依靠自身的散热部进行散热无法满足散热要求。另一方面，电路板上设有温控器，当温度超过安全值时，温控器会切断电源，电陶炉停止工作，这样会经常导致电陶炉在使用时被中断使用，给使用者带来了麻烦。A power control element is provided on the circuit board to adjust the heating power of the heating plate. During operation, the power control element generates heat through its own heat dissipation part to dissipate heat to ensure the normal operation of the power control element. However, in actual use, the user has a large adjustment range for the power control element, causing the temperature of the power control element to rise sharply, and relying only on its own heat dissipation part for heat dissipation cannot meet the heat dissipation requirements. On the other hand, there is a thermostat on the circuit board. When the temperature exceeds the safe value, the thermostat will cut off the power supply, and the electric ceramic stove will stop working. This will often cause the electric ceramic stove to be interrupted when it is in use. brought trouble.
为了解决上述问题，市场上现有很多电陶炉对机芯的散热结构进行了改进，如增加散热块，散热块与功率控制元件的发热部接触，通过增大发热面积，提高散热效率。但是，块状的散热块的散热效果仍不明显，依然无法满足电陶炉机芯的散热要求。In order to solve the above problems, many electric ceramic furnaces on the market have improved the heat dissipation structure of the core, such as adding a heat dissipation block, which is in contact with the heating part of the power control element, and the heat dissipation efficiency is improved by increasing the heating area. However, the heat dissipation effect of the massive heat dissipation block is still not obvious, and still cannot meet the heat dissipation requirements of the electric ceramic stove core.
