Compared with the prior art, the electric heating blackboard has the advantages that: the heating layer is arranged on the back of the panel and can conduct heat to the panel to make the panel dissipate heat to the air, the panel has the writing function and can serve as a heat conducting plate, the writing function of the blackboard and the heating function of a warmer are well combined, and the electric heating blackboard has multiple purposes, is more economical, does not occupy a space and can create a warm and comfortable teaching environment for students.
Description
Technical field
The present invention relates to a kind of blackboard, relate in particular to a kind of blackboard with electric heating function.
Background technology
At present, common blackboard comprises panel, backboard and frame, and the panel front end face can be write, and backboard is located at back side of panel and is used for supporting, and frame gets up panel and backboard all around.A lot of improvement structures to blackboard are arranged in the prior art, but all be basically at writing function, as dust-free blackboard, Sliding blackboard, magnet board, driven blackboard, blackboard movable up and down, lamination blackboard etc., it is single that the function of use of blackboard shows slightly, a kind of blackboard in conjunction with the electric heating function do not occur.Some have heating arrangement behind panel public technology document is disclosed though also have in the prior art, as the patent No. is Chinese utility model patent " wet rubbing electrothermal the dust-free blackboard " (Granted publication number: CN2700125Y) of ZL200420017343.0, heating arrangement in this patent is used for behind the wet rubbing the quick desiccation of blackboard, play the effect of an oven dry, its heating-up temperature is more limited, and far can not reach the function of bringing heating to instructional space, similarly can also be with reference to CN201604441U and CN2140304Y.
Summary of the invention
Technical problem to be solved by this invention is that a kind of electric heating blackboard with heating heating function is provided at the above-mentioned state of the art.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of electric heating blackboard, it is characterized in that comprising panel that the surface is used to write and the backboard that is used to support, the back side that it is characterized in that described panel be provided with can conduct heat on the panel so that panel to the heating layer of air heat conduction, and, be provided with thermal insulation layer between aforesaid heating layer and the aforesaid backboard.
As improvement, the heat of heating layer is gone out by panel heat conduction as much as possible, be provided with heat-insulation layer between described heating layer and the thermal insulation layer.
Be provided with the frame that the cross section is a U-shaped around described panel and the backboard, described heating layer, thermal insulation layer and heat-insulation layer then are positioned at this frame.
Described panel can adopt metal material or safety glass.
Described heat-insulation layer can adopt the ceramic fiber paper material.Can certainly adopt insulation material commonly used.Here enumerate no longer one by one.
Described thermal insulation layer adopts extruded sheet.Can certainly adopt heat-barrier material commonly used.Here enumerate no longer one by one.
Described backboard adopts galvanized steel plain sheet.Can certainly adopt other metals or nonmetallic materials.Here enumerate no longer one by one.
Heating board or the heating film of described heating layer for adopting electrically conductive ink, carbon crystalline substance, carbon fiber, nichrome or macromolecule conductive film to make.
Described heating board or heating film are connected in the heating loop and comprise at least two blocks of heat-generating units plates that are connected in parallel or heat-generating units film, every block of heat-generating units plate or heat-generating units film cascade have a temperature detect switch (TDS) and fuse, and, aforesaid heating is in series with a filter capacitor and circuit board in the loop, has temperature controller and power switch on this circuit board.Can certainly adopt a heat-generating units plate.
Perhaps, described conducting film is connected in the heating loop and comprises at least two conductive unit films that are connected in parallel, every conductive unit film cascade has a temperature detect switch (TDS) and fuse, and, aforesaid heating is in series with a filter capacitor and circuit board in the loop, has temperature controller and power switch on this circuit board.
Compared with prior art, the invention has the advantages that: by increasing heating layer in panel back, heating layer can conduct heat on the panel so that panel to air heat conduction, panel except writing function also as a heat-conducting plate, with the heating function of the writing function of blackboard and warmer well in conjunction with together, one-object-many-purposes, more economically, do not take up space can be built a cosy teaching environment to the student.Because the panel heat-conducting area is big, can improve room temperature fast in the short time again, heating effect is good.
Description of drawings
Fig. 1 is the example structure schematic diagram.
Fig. 2 is the embodiment cutaway view.
Fig. 3 is an electrothermal layer structural representation among Fig. 1.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, electric heating blackboard in the present embodiment does not have great difference with existing blackboard in appearance, but has the heating heating function, concrete from comprising panel 2, heating layer 3, heat-insulation layer 4, thermal insulation layer 5 and backboard 6 outside to inside successively, and with around push up with the frame 1 of U-shaped and to be consolidated, heating layer 3, thermal insulation layer 5 and 4 of heat-insulation layers are positioned at and are wrapped in frame 1.
Heating board is connected in the heating loop and comprises six blocks of heat-generating units plates 31 that are connected in parallel, and insulated enclosure between the adjacent heat-generating units plate 31 can certainly adopt a heat-generating units plate.Every block of heat-generating units plate 31 is in series with a temperature detect switch (TDS) 32 and fuse 33, and heating is in series with filter capacitor 36 and circuit board 37 in the loop, has temperature controller 38 and power switch 39 on this circuit board 37.Wherein, temperature detect switch (TDS) 32 is attached on the heat-generating units plate 31, can control electric current, opens or closes electric current when heat-generating units plate 31 reaches a certain temperature; Fuse 33 is in order to overcurrent protection; Filter capacitor 36 is in order to reduce electromagnetic radiation, guarantees safe in utilizationly, and temperature controller 38 has temp probe also can regulate electric heating blackboard input current and temperature, can control temperature controller 38 and power switch 39 by remote controller, very convenient.
Heat-generating units plate 31 electric after, heating layer 3 conduct heat on the panel 2 so that panel 2 to air heat conduction, again because of the existence of heat-insulation layer 4 and thermal insulation layer 5, can guarantee heat as much as possible by panel 2 to air heat conduction, to prevent that heat is transmitted on the backboard 6, because of backboard 6 and metope lean on closer, so the existence of heat-insulation layer 4 and thermal insulation layer 5 can prevent to burn out body of wall.The general requirement when the electric heating blackboard is installed, backboard 6 and wall are at interval more than 1 centimetre.
Adopt the electric heating blackboard in the present embodiment, can replace heating installations such as traditional warmer, stove in winter, can build a cosy teaching environment, and hiddenly do not take up space, use easy to operate to the student.Because the panel heat-conducting area is big, can improve room temperature fast in the short time again, heating effect is good.
