In order to achieve the above object, the temperature of the limit certainly electric heating piece table that the utility model is designed, comprise the table body of forming by table frame and desktop, be provided with from limitting warm electric heating piece in the described table body, play thermal effect, the described sheet material of limitting warm electric heating piece to be made by the PTC exothermic material certainly forms, and is provided with two electrodes in the described sheet material, and sheet surface is provided with dielectric film.After electrode connected power line, electric current arrived another electrode through an electrode by sheet material, formed the loop, sheet material energising back heating, and the temperature rising, the sheet material expanded by heating makes the part current channel disconnect, and the electric current that passes through reduces, and caloric value reduces thereupon; When temperature rose to certain scope, sheet resistance increased, and nearly all became to open circuit, and the electric heating piece power supply equals to cut off; And when temperature reduced, sheet resistance reduced, and electric current increases, and electric heating piece begins to supply with heat again, and himself temperature is remained within the specific limits.The ptc material of limitting warm electric heating piece certainly that is applied on the plate face can temperature as required be selected.Stationary temperature is provided with from limitting warm electric heating piece at the more position of table body human body contact the human body good warmth retention effect.Sheet material also can be formed by other plastic semiconductor exothermic material, reaches the function of heating limit temperature, and effect is equal to.
As preferably, the plane is provided with from limitting warm electric heating piece on the described desktop, and the plane is the position of the more contact of human body on the table body; The last plane of described desktop is provided with and the fitting recess of limitting warm electric heating piece to match certainly, limits warm electric heating piece to be located in the fitting recess certainly, and the height after assembling is consistent with height of table top.Described the top can be polyurethane, felt, foam sponge, benzene plate etc. with an outer cover capping, heat-insulation layer material from limitting warm electric heating piece below to be provided with heat-insulation layer, and outer cover material can be gauze or cortical material etc.Because limit the characteristics of warm electric heating piece material certainly, available glue is bonding, and is fixing spacing.Described heat-insulation layer below is provided with reflectance coating, and reflect heat is gone back to the upper strata from limitting warm electric heating piece, further reduces the loss of heat, and transmitting film can be aluminium foil transmitting film etc.
As preferably, described electrode respectively connects a lead, and two leads are set in parallel in the sheet material, have the operating characteristics of continous-stable; Described electrode is 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.
The temperature of the limit certainly electric heating piece table that the utility model obtains is used from limitting warm electric heating piece as calandria the table body to be heated, omitted the attemperating unit of other heating element heaters, 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, and the human body comfort is good; It is few that the loss of heat-insulation layer and reflecting layer heat is set, energy utilization rate height.
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: table frame 1, desktop 2, fitting recess 3, limit warm electric heating piece 4, sheet material 5, electrode 6, groove 7, lead 8, table body 9, heat-insulation layer 10, reflecting layer 11, outer cover 12 certainly.
The specific 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 warm electric heating piece table of limitting certainly that present embodiment is described comprises a body 9 of being made up of table frame 1 and desktop 2, fitting recess 3 is set on plane on the desktop 3, be located in the fitting recess 3 from the warm electric heating piece 4 of limit, below from the warm electric heating piece 4 of limit is provided with heat-insulation layer 10, and the heat-insulation layer material can be polyurethane, felt, foam sponge, benzene plate etc.Be provided with reflectance coating 11 below heat-insulation layer 10, reflectance coating 11 can be aluminium foil reflectance coating etc.With an outer cover 12 cappings, outer cover 12 materials can be gauze or cortical material etc. from the top of limitting warm electric heating piece 4.The described sheet material 5 of limitting warm electric heating piece 4 to be made by the PTC exothermic material certainly forms, and the switch temperature of the ptc material of selecting for use is about 35 degree, and the ptc material of selecting for use can temperature as required be selected.Be provided with two electrodes 6 in the described sheet material 5, sheet material 5 surfaces are provided with dielectric film, and described electrode 6 respectively connects a lead 8, two leads 8 and is set in parallel in the sheet material 5, has the operating characteristics of continous-stable.Described electrode 6 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 5 and respectively near the two ends of sheet material 5, described sheet material 5 is provided with groove 7 between two leads 8, internal stress when reducing sheet material 5 and expanding with heat and contract with cold, in order to make this better effects if, described groove 7 is a rectangle.
