And the opening surface of one half container bodies 10,10 is engaged and constitute heater element, according to this heater element, the lid 11 that needn't be shaped in addition, so, can reduce the cost of metal die.Compare with the situation that only forms envelop 1, because the basal area of envelop 1 is big, so can easily form the big heater element of total amount of heat with 1 half container body 10.
When igniting portion 5 is formed heater element with respect to body 4 bending, body 4 is used with the state that erects, because igniting portion 5 is towards oblique or towards laterally projecting, so, can make vertical up lighter or the flame of match contact igniting portion 5 easily, therefore, ignition operation is easy.
With igniting portion 5 and body 4 as dividing other parts formation, filling the body 4 of exothermic mixture 2 with filling the igniting portion 5 of igniting agent 3 engage and constitute heater element.According to this heater element, when forming igniting portion 5, can not be subjected to the influence of shape, structure or its method for making of body 4, so, can make the optimizations such as shape, structure, shaping base material of igniting portion 5.For example, because igniting portion 5 is shorter than body 4, so, deep-draw handling ease, and available low-cost formation.In addition, also the useful ceramics formed products forms.
Body 4 and igniting portion 5, can with the ora terminalis of body 4 and igniting portion 5 each other crimping engage, but with both 4,5 when being connected and fixed, can carry out the operation that engages of body 4 and igniting portion 5 by screw thread 15 rapidly expeditiously, the igniting agent 3 of consolidating shapeization can be connected airtight with exothermic mixture 2 with suppressing.During igniting agent 3 burning, produce the burning gases of many igniting agent 3 self or the burning gases of its contained impurity, at this moment, the leak tightness of envelop 1 is high more, and the flame of high temperature and spark are from the protruding end of igniting portion 5 or the partly easy more ejection of burn.But, if by screw thread 15 body 4 is connected with igniting portion 5, then above-mentioned burning gases are emitted from the gap at screw thread peak, and igniting portion 5 internal pressures raise unusually in the time of can stoping burning, can avoid the flame or the spark ejection of high temperature when igniting, the security when improving igniting.In addition, also avoided along with flame or spark spray igniting portion 5 outsides and the heat loss of generation.
In the heater element that body 4 and igniting portion 5 is engaged and constitute, in body 4 and igniting portion 5, fill up exothermic mixture 2 and igniting agent 3 respectively.But, if in advance admittedly the igniting agent 3 of shapeization install to form in the igniting portion 5, then when engaging operation, can prevent trickling down of igniting agent 3 conscientiously, so can engage operation expeditiously.When engaging operation, exothermic mixture 2 and igniting agent 3 can not mix yet.
With the heating appliances of above-mentioned heater element H as thermal source, make heater element H heating, should heat pass to the processing object by heat transfer part 22.For example, in the time of removing the frost that is attached on the automotive window, the heat of heater element is passed to frost (processing object) by heat transfer part 22,, remove frost by the effect of scraping and the hot effect of melting of heat transfer part 22 to frost.
With the heater element of foil formation envelop 1, its cost of manufacture is low.Therefore, the consumer cost of heater element needn't be worried, heater element can be utilized like a cork.
