As preferably, electrode respectively connects a lead, and two leads are set in parallel in the sheet material, have the operating characteristics of continous-stable; Described plate face is made up of the upper and lower, and is described from limitting warm electric heating piece to place between the upper and lower, because limit the characteristics of warm electric heating piece material certainly, the jointing plate face runs off heat and reduces so well; Described the upper and lower can be provided with connector and connect, and both are fixed together, not random shift position; Described plate face can be insulation material, insulation material can be polyurethane, foam sponge, benzene plate or felt etc., reduce the loss of heat, described lower floor is provided with reflectance coating, reflectance coating can be an aluminium foil reflectance coating etc., reflect heat is returned from limitting warm electric heating piece, further improve the heat utilization rate; Described electrode can be made of the strands of metal wire that is woven into the normal shape of shape bar, is embedded in the sheet material centre also respectively near the two ends of sheet material, and heating effect is better; Described sheet material can be provided with groove between two leads, the internal stress when reducing sheet material and expanding with heat and contract with cold, and in order to make this better effects if, described groove can be rectangle, also can be analogous shapes such as oval shape; Can be provided with on the interior contact-making surface on described upper strata and the stopper slot of limitting warm electric heating piece geomery to match certainly, like this can be spacing to limitting warm electric heating piece to carry out certainly, can arbitrarily not move, also can all be provided with stopper slot on the interior contact-making surface of the upper and lower layer of the interior contact-making surface on upper strata, perhaps only the interior contact-making surface of lower floor is provided with stopper slot, reaches the effect that is equal to; Described connector can be hinge arrangement, and is economical and practical.
The temperature of the limit certainly electric heating piece platen that the utility model obtains is used from limitting warm electric heating piece as heating element the plate face to be heated, omitted the attemperating unit of other heating elements, can vary with temperature the heating power of adjusting self, its temperature is remained within the specific limits, safe and reliable, the effect of limit temperature obviously is suitable for large range promotion use; Sheet material is frivolous, and the material softness, jointing plate face preferably, and heat runs off few, and the energy utilization rate improves.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the utility model is from the structural representation of limitting warm electric heating piece.
Among the figure: plate face 1, upper strata 2, lower floor 3, connector 4, limit warm electric heating piece 5, sheet material 6, electrode 7, groove 8, stopper slot 9, lead 10 certainly.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1 and Figure 2, the temperature of the limit certainly electric heating piece platen that present embodiment is described, it mainly comprises plate face 1, described plate face 1 is provided with from limitting warm electric heating piece 5, the described sheet material 6 of limitting warm electric heating piece 5 to be made by the PTC exothermic material certainly forms, manufacturing materials is the ptc material that switch temperature is about 35 degree, and the high molecular PTC exothermic material of selecting for use can temperature as required be selected.Be provided with two electrodes 7 in the described sheet material 6, sheet material 6 surfaces are provided with dielectric film, and described electrode 7 respectively connects a lead 10, two leads 10 and is set in parallel in the sheet material 6, has the operating characteristics of continous-stable.Described plate face 1 is made up of upper strata 2 and lower floor 3, described from limitting warm electric heating piece 5 to place between upper strata 2 and the lower floor 3, upper strata 2 is provided with connector 4 with lower floor 3 and is connected, connector 4 is a hinge arrangement, described electrode 7 is made of the strands of metal wire that is woven into the normal shape of shape bar, be embedded in the middle of the sheet material 6 and respectively near the two ends of sheet material 6, described sheet material 6 is provided with groove 8 between two leads 10, internal stress when reducing sheet material 6 and expanding with heat and contract with cold, in order to make this better effects if, described groove 8 is a rectangle; The interior contact-making surface on described upper strata 2 is provided with and the stopper slot 9 of limitting warm electric heating piece 5 geomeries to match certainly, like this can be spacing to limitting warm electric heating piece 5 to carry out certainly, can arbitrarily not move, and upper strata 2 and lower floor 3 also can all be provided with stopper slot 9, reach the effect that is equal to.Plate face 1 is an insulation material, and insulation material can be polyurethane, foam sponge, benzene plate or felt etc., reduces the loss of heat, described lower floor 3 is provided with reflectance coating, reflectance coating can be an aluminium foil reflectance coating etc., and reflect heat is returned from limitting warm electric heating piece 5, further improves the heat utilization rate.
