Description of the invention: [Technical field to which the invention pertains] The present invention relates to a degreasing structure of a range hood, in particular to an ageing structure set in the wind and stomach, and after the heat of the spleen stomach (4) is melted by heating The degreasing structure that flows smoothly. [Prior Art] When the existing range hood is used, it can be ventilated through a stomach installed in the exhaust fumes (4), and then the fumes generated during cooking can be sucked into the hood inside the casing and released. Outdoors; however, although the range hood can extract most of the fumes produced by the wind and stomach, but the wind and stomach are long-term _ after use, it is easy to produce oily collapse attached to the stomach: body wall On the 'not only will form dirt on the stomach and stomach, it needs to be disassembled, and the β-washing will have an impact on the soot pumping efficiency. There are still improvements. In order to improve the use of the above-mentioned range hood, as shown in Figure 1, 'the Republic of China patent singer D-528148 proposes a heat venting device for the hood, mainly in the wind In the manner of the outer wall of the stomach, a thermal resistance device 12 is attached to the outside of the windy day 11 of the exhaust hood 1; wherein the thermal resistance device 12 is a thin type of electric energy element of the shape of L, which is tied to two layers. The insulating layer is coated with a heat conducting layer and a conductive layer, and the conductive layer is conducted by the heat conducting layer to the outside of the wind stomach 11 attached to the wind, and is accumulated in the wind. The oil collapse of the inner wall of the inner wall is melted by heat, and then discharged through the oil draining structure. 201221870 achieves the purpose of electric heat removal. However, when implemented according to the foregoing structure, the thermal resistance device 12 is attached to the wind and stomach 11 in a curved curved surface with a continuous arrangement of conductive thin wires and an insulating layer for bending the conductive thin wire of the heating field. The resistance value will decrease with the change of the cross section, which will cause the section to be overheated after power-on, or the It-shaped burned by the station 4, even forming a leakage on the wind and stomach; seeing, not only affects the safety and stability of the thermal resistance device. Sexuality will also increase the power of the thermal resistance device, resulting in % unnecessary loss. In addition, the above structure is capable of attaching the two insulating layers to the wind-stomach curve, which is composed of a soft rubber layer, and instead forms an effect of heat insulation on the heat-conducting layer and the wind-stomach, thus requiring a high temperature and a high temperature. The heat effect of heat dissipation causes the oil on the inner wall of the wind and stomach to be dissolved. 'In addition to increasing the power consumption of the thermal resistance device, and the frequent and large temperature rise and fall process, the two insulating layers are easily deteriorated and the structural strength is reduced. When the crack occurs in the layer structure, the oil mist is adhered to the thermal resistance device, which also causes the above-mentioned leakage phenomenon. It is not only unable to conduct electricity, but also loses the effect of removing heat by electric heat, which is a big problem for the safety of use.
