背景技术Background technique

电陶炉由于其热效高、加热快、多用性日益成为人们喜爱的厨具。现有的大部分电陶炉采用风扇强制散热，少部分采用金属外壳自然散热。现有的散热方式存在以下明显的缺陷：Because of its high thermal efficiency, fast heating, and versatility, electric ceramic stoves are increasingly becoming popular kitchen utensils. Most of the existing electric ceramic stoves use fans for forced heat dissipation, and a few use metal shells for natural heat dissipation. The existing heat dissipation method has the following obvious defects:

1、噪音，当风扇工作时，风扇运行会产生一定噪音，噪音会对人的生活和工作造成干扰；1. Noise, when the fan is working, the fan will generate a certain amount of noise, which will interfere with people's life and work;

2、散热不均，当接近风扇最近的地方热量流通很快，而远离风扇的地方，热量聚集不流通；聚集不流通的热量时间过长，造成电器的性能和功能大大下降，久之会造成安全隐患；2. Uneven heat dissipation. When the heat is close to the place closest to the fan, the heat circulates quickly, but the heat accumulates and does not circulate in the place far away from the fan. If the heat accumulates and does not circulate for too long, the performance and function of the electrical appliance will be greatly reduced, which will cause safety hazards over time. Hidden danger;

3、效率低，大量的热被散热消耗掉，热能未被充分利用。3. The efficiency is low, a large amount of heat is consumed by heat dissipation, and the heat energy is not fully utilized.

4、性能低，安全隐患多，用风扇散热时，当风扇出现故障时，整个电器散热系统会瘫痪，散热系统瘫痪后，如果电器还能工作的情况下，会容易引起电器起火或触电的危险。4. Low performance and many potential safety hazards. When the fan is used for heat dissipation, when the fan fails, the entire electrical cooling system will be paralyzed. After the cooling system is paralyzed, if the electrical appliance can still work, it will easily cause electrical fire or electric shock. .

5、有风扇强制散热的电陶炉可以采用塑料材料制作外壳，没有风扇的电陶炉只能采用金属或高耐热材料制作外壳；5. Electric ceramic stoves with fans for forced heat dissipation can use plastic materials to make shells, and electric ceramic stoves without fans can only use metal or high heat-resistant materials to make shells;

6、受散热条件所限影响，大多数产品为一呆板平面，缺乏更实用的更美的产品造型。6. Due to the limitation of heat dissipation conditions, most products are a rigid plane, lacking more practical and beautiful product shapes.

具体实施方式Detailed ways

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明作进一步详细说明。应当理解，此处说描述的具体实施例仅仅用于解释本发明，并不用于限定本发明。In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

如图1所示，自然散热型节能电陶炉，其至少包括：由上而下叠置的微晶板1、炉盘2、承托炉盘的支架装置、底壳3，所述炉盘电连接一控制电路板4，所述微晶板镶嵌在装饰环5内，装饰环固定在隔热套管6的顶部，隔热套管的底部固定在所述底壳上，隔热套管置于面壳7的中心口内，面壳合拢后盖在底壳之上，所述底壳上设有多个进风口3a，所述隔热套管由面壳的中心口中向上伸出、在伸出面壳处的侧壁上设有多个出风口6a。隔热套管将炉盘2围在其中心，形成一个炉腔。进、出风口之间形成立体的向上的散热风道，冷空气由底壳上的进风口3a进入，对面壳和底壳围拢的炉腔进行冷却，冷空气被加热后，产生烟道效应，由靠近隔热套管顶部的出风口6a流出。藉此对电陶炉进行自然散热。由于取消了散热风扇，故此减少了故障率、电能消耗，也不再有噪音。并且热空气由出风口6a出来后在微晶板1的周围形成一个圆柱形的热隔离区，能将放置在微晶板1上的茶壶（或炊具）包裹在内，有一定的保温作用，能减少茶壶向外辐射和传导热能，有利于节能降耗。As shown in Figure 1, the natural heat dissipation energy-saving electric ceramic furnace at least includes: amicrocrystalline plate 1 stacked from top to bottom, afurnace pan 2, a bracket device for supporting the furnace pan, and abottom shell 3, the stove pan Electrically connected to acontrol circuit board 4, the microcrystalline plate is embedded in thedecorative ring 5, the decorative ring is fixed on the top of the heat-insulatingsleeve 6, the bottom of the heat-insulating sleeve is fixed on the bottom shell, and the heat-insulating sleeve Placed in the central opening of theface shell 7, the face shell is closed and covered on the bottom shell, the bottom shell is provided with a plurality ofair inlets 3a, and the heat insulating sleeve protrudes upwards from the central opening of the face shell, A plurality ofair outlets 6a are provided on the side wall protruding from the face shell. The heat-insulating sleeve surrounds thefurnace pan 2 at its center to form a furnace chamber. A three-dimensional upward heat dissipation air duct is formed between the air inlet and outlet. The cold air enters through theair inlet 3a on the bottom shell to cool the furnace cavity surrounded by the surface shell and the bottom shell. After the cold air is heated, a flue effect is generated. It flows out from theair outlet 6a near the top of the heat insulating sleeve. In this way, the electric ceramic stove is naturally dissipated. Due to the cancellation of the cooling fan, the failure rate and power consumption are reduced, and there is no more noise. And after the hot air comes out from theair outlet 6a, a cylindrical heat isolation zone is formed around themicrocrystalline plate 1, which can wrap the teapot (or cooking utensil) placed on themicrocrystalline plate 1, and has a certain heat preservation effect. It can reduce the external radiation and heat conduction of the teapot, which is beneficial to energy saving and consumption reduction.

为加大出风口的面积，底壳3改变了以往近乎平面的结构，其厚度大为增加，形成两层进风口。参看图1、3、4，其在位于隔热套管内侧的位置向下凹陷，凹陷部分大体呈圆筒状，其侧壁和底板上设有多个所述进风口3a。底壳的进风口3a采用错层式设计，底板上有多道紧密排列的栅条，从上往下看，相邻栅条之间没有缝隙；从侧面看，相邻栅条交错分布，一条向上隆起栅条3e其相邻的栅条就是一条向下凹陷的栅条3f，进风口3a就位于相邻栅条之间的开口处。底壳的侧壁上也按此结构设置进风口。藉此在增大进风量的同时，还避免了炉具内部热能直接辐射桌面，避免长时间工作烤坏台面。为加大底板与台面的间距，在底壳底面设有多个支持脚3b。In order to increase the area of the air outlet, thebottom shell 3 has changed the previous nearly planar structure, and its thickness has been greatly increased to form two layers of air inlets. Referring to Figures 1, 3, and 4, it is recessed downward at the position inside the heat insulating sleeve, and the recessed part is generally cylindrical in shape, and a plurality ofair inlets 3a are provided on its side wall and bottom plate. Theair inlet 3a of the bottom shell adopts a split-level design, and there are multiple closely arranged grid bars on the bottom plate. From the top to the bottom, there is no gap between adjacent grid bars; Theadjacent grid bar 3e raised upwards is agrid bar 3f sunken downwards, and theair inlet 3a is located at the opening between the adjacent grid bars. Air inlets are also arranged according to this structure on the side wall of the bottom case. In this way, while increasing the air intake, it also prevents the heat energy inside the stove from directly radiating the tabletop, and avoids the tabletop being damaged by long-term work. In order to increase the distance between the bottom plate and the table top, a plurality of supportingfeet 3b are provided on the bottom surface of the bottom case.
