常见的多士炉的电热板是以云母片为基板，在云母片上缠绕发热丝，为了固定发热丝或防止发热丝受热膨胀，会在云母片上用云母压条压住发热丝，把云母片和云母压条固定在一起。The electric heating plate of the common toaster is based on the mica sheet. The heating wire is wound on the mica sheet. In order to fix the heating wire or prevent the heating wire from being thermally expanded, the mica sheet will be used to press the heating wire with the mica bead, the mica sheet and the mica The bead is fixed together.

本实施例中，各电热板20的基板为云母板。选用云母板作为基板，是一种优质的绝缘材料，具有无毒，无味，耐高温，导热性能好的优点，适用于在多士炉中进行应用。In this embodiment, the substrate of each electric heating plate 20 is a mica plate. Choosing mica board as the substrate is a high-quality insulating material, which has the advantages of non-toxic, odorless, high temperature resistance and good thermal conductivity, and is suitable for application in toasters.
参见图6、图8、图9、图11所示，各电热板20中发热金属膜的发热电路在其基板的表面来回延伸形成蛇形均匀排布结构，能够使发热均匀，性能稳定。还需要说明的是，发热电路的长度、间隙、粗细在实际应用中可依据需要而自由设计。以及，发热电路的排布延伸方式不限于附图，还可以依据需求绕成其它的各种形状。6, 8, 9, and 11, the heating circuits of the heating metal films in each electric heating plate 20 extend back and forth on the surface of the substrate to form a serpentine uniform arrangement structure, which can make the heating uniform and the performance stable. It should also be noted that the length, gap, and thickness of the heating circuit can be freely designed according to needs in practical applications. And, the arrangement and extension of the heating circuit is not limited to the drawings, but can also be wound into other shapes according to requirements.
各电热板20中发热金属膜的发热电路首末端均设置有电源接点24。这些电源接点24可以方便地实现接线，实现电热板20中发热金属膜的发热电路的导电。选材时，发热金属膜为电阻膜，在通电后能够发热。Each heating plate 20 is provided with a power contact 24 at the first end of the heating circuit of the heating metal film. These power supply contacts 24 can be easily connected to realize the conduction of the heating circuit of the heating metal film in the electric heating plate 20. When selecting materials, the heating metal film is a resistive film, which can generate heat after being energized.
除此之外，还可以在各发热金属膜的表面覆盖一层导热板25，利用多个铆钉26使导热板25与基板相连接，这样发热金属膜位于基板与导热板25之间形成夹芯结构。一方面，可以利用导热板25将发热金属膜压住，防止发热金属膜受热膨胀从基板中脱落。另一方面，导热板25的设置可以使发热金属膜的热量均匀化，面包片烘烤热量均匀口感更好，不会将面包片的局部烤焦。本实施例中，所述导热板25为云母板，所述导热板的厚度小于基板的厚度，实际生产中，导热板的厚度选择0.1mm到0.2mm为宜。从而薄的导热板允许热量散发，而更厚的基板具有隔热功能。需要说明的是，附图中的导热板25绘制时为局部结构，是为了更好地展示发热金属膜的排布，实际上是导热板25铺设覆盖于发热金属膜的整面。In addition, the surface of each heat-generating metal film can be covered with a layer of heat-conducting plate 25, and a plurality of rivets 26 are used to connect the heat-conducting plate 25 to the substrate, so that the heat-generating metal film is located between the substrate and the heat-conducting plate 25 to form a sandwich structure. On the one hand, the heat conductive plate 25 can be used to hold down the heat generating metal film to prevent the heat generating metal film from expanding and falling off the substrate. On the other hand, the provision of the heat conducting plate 25 can make the heat of the heat-generating metal film uniform, and the baking heat of the sliced bread is evenly tasted, and will not scorch part of the sliced bread. In this embodiment, the thermally conductive plate 25 is a mica plate, and the thickness of the thermally conductive plate is smaller than the thickness of the substrate. In actual production, the thickness of the thermally conductive plate is preferably 0.1 mm to 0.2 mm. Thus, the thin heat-conducting plate allows heat to be dissipated, while the thicker substrate has a heat insulation function. It should be noted that the heat conductive plate 25 in the drawing is a partial structure when drawn, in order to better show the arrangement of the heat generating metal film, in fact, the heat conductive plate 25 is laid to cover the entire surface of the heat generating metal film.
还有，各电热板20的上端和下端均设有多个可以卡合在框架10上的凸位27，这些凸位27的形状和数据可以依据实际需求而设定。In addition, the upper and lower ends of each heating plate 20 are provided with a plurality of protrusions 27 that can be engaged on the frame 10, and the shape and data of these protrusions 27 can be set according to actual needs.
本发明之电热板20的产生成型工艺如下：选取云母板作为基板，将整片无空洞的发热金属膜通过粘胶层粘合在云母板上，再通过蚀刻或者雕刻去除发热金属膜的一部分，以形成来回延伸的发热电路。最后在表面铺上导热板25，在导热板25与基板之间打上多个铆钉26，使发热金属膜形成夹芯结构，注意铆钉26的位置应该避让开发热电路。The forming process of the electric heating plate 20 of the present invention is as follows: the mica plate is selected as the substrate, the entire heating metal film without voids is adhered to the mica plate through the adhesive layer, and then a part of the heating metal film is removed by etching or engraving, To form a heating circuit extending back and forth. Finally, a heat conductive plate 25 is laid on the surface, and a plurality of rivets 26 are punched between the heat conductive plate 25 and the substrate to form a sandwich structure of the heating metal film. Note that the position of the rivets 26 should avoid developing thermal circuits.
装配时，将中间电热板22安装在框架10的中间，将框内的内部空分一分为二，然后，左侧电热板21和右侧电热板23分别安装于框架10的左右两侧，左侧电热板21有发热金属膜的一面朝向第一烘烤室31，右侧电热板23有发热金属膜的一面朝向第二烘烤室32，则两个烘烤室30的左右两面均有发热金属膜，能够提高对面包片的烘烤效率。During assembly, the middle heating plate 22 is installed in the middle of the frame 10, the internal air separation in the frame is divided into two, and then the left heating plate 21 and the right heating plate 23 are installed on the left and right sides of the frame 10, The side of the left heating plate 21 with the heating metal film faces the first baking chamber 31, and the side of the right heating plate 23 with the heating metal film faces the second baking chamber 32, both left and right sides of the two baking chambers 30 The heating metal film can improve the baking efficiency of the sliced bread.
使用时，将面包片放入烘烤室30内，旋动定时旋钮，即开始烘烤面包片。由于本发明示例中的多士炉有2个烘烤腔，因此一次性可以烤2片面包。In use, the bread slices are put into the baking chamber 30, and the timing knob is turned to start baking the bread slices. Since the toaster in the example of the present invention has two baking cavities, two slices of bread can be baked at once.
本发明的设计重点在于，由于在多士炉框加的边侧位置安装二侧电热板、在二侧电热板之间安装中间电热板，每相邻的两电热板之间构成用于烘烤面包片的烘烤室，各电热板均包括基板和发热金属膜，其中二侧电热板仅在其基板朝向烘烤室的表面粘合发热金属膜，中间电热板分别在其基板的正反两个面均粘合发热金属膜。这样，可以保证每个烘烤室30两面均具有发热金属膜，可以提高对面包片的烘烤效率，而背向烘烤室30的相应基板表面上无发热金属膜，避免不必要的加热升温导致能耗损失。The design focus of the present invention is that since two side heating plates are installed at the side of the toaster frame, and an intermediate heating plate is installed between the two side heating plates, each adjacent two heating plates are configured for baking In the baking room of bread slices, each electric heating plate includes a substrate and a heating metal film, wherein the two-side electric heating plate only bonds the heating metal film on the surface of the substrate facing the baking room, and the middle electric heating plate is respectively on the front and back of the substrate All surfaces are bonded with heating metal film. In this way, it can be ensured that each baking chamber 30 has a heating metal film on both sides, which can improve the baking efficiency of the bread slices, and there is no heating metal film on the surface of the corresponding substrate facing away from the baking chamber 30, to avoid unnecessary heating and heating Resulting in loss of energy consumption.
