  The conventional electric heating board is used by being fixed to a counter or the like. However, the electric heating board is attached as it is when not in use, and there is a possibility that the heating surface may be damaged due to other objects coming into contact with the heating surface. Further, the heat generation surface facing outward may be soiled. Further, since the electric heating board is fixed, there is a possibility that it may be damaged by removal when it is necessary to replace it, or it takes time to remove. Furthermore, there is a problem in use such that the area cannot be enlarged or reduced according to the length of the mounting location.

  This device makes the electric heating board a standardized shape, and by increasing or decreasing the number of the electric heating boards according to the expansion and contraction of the heating area, it is possible to adjust the expansion of the heating area, and to replace and fix the front and back, The conventional problems have been solved.

  That is, the surface side (electric heating panel) exposes the heat generating surface or is covered with a heat transfer plate, and therefore is often relatively weak against impact force. Further, since the back surface can be made of a hard board or other material having high strength, it is said that it can sufficiently cope with the impact force. Therefore, when the electric heating board is used (for example, in winter), the electric heating panel is exposed to the room, and when it is not used (for example, in summer), if the hard board is exposed to the room, contact with other objects or impact Could withstand. Further, the electric heating panel can be firmly protected by fixing the electric heating board to the fixing plate and providing an edge frame around the four sides of the fixing plate.

  That is, this invention is an electric heating board characterized by combining an edge frame including a plurality of wired edge frames, an electric heating panel fixing plate, and an electric heating panel detachably attached to the electric heating panel fixing plate. Yes, the left and right edge frames are connected and fixed to the left and right edges of a single frame or a plurality of connecting frames of the fixing frame with the edge frame, which is fixed to the edge frames of the fixing plate of the electric heating panel. An electric heating board that is detachably attached to the inner side of the fixing plate. The electric heating panel is fixed to the recessed part provided on the upper and lower side edges of the electric heating panel, inside the edge frame. A convex part that can be moved in and out is fitted.

  In another aspect of the invention, the electric heat panel has a heat insulating plate layered on the inside of the decorative plate, an electric heater layered on the inner side of the heat insulating plate, and an insulating heat transfer plate layered on the inner side of the electric heater. The terminal of the electric heater and the wiring terminal in the edge frame are contact-connected, and the edge frame and the fixing plate constituting the electric heating board correspond to single or plural connection of the fixing plates. Then, the edge frames are connected, and the heat generating panels are fixed to the fixing plates, respectively, so that the heat generating area can be selected from wide and narrow.

  Furthermore, the electric heating panel has a heat transfer surface on one side and a decorative plate on the other side, and the heat transfer surface and the installation side of the decorative plate surface can be selected. It is an adhesive stopper.

  The electric heating panel in the above-mentioned device is obtained by applying carbon particles to an insulating film or board or layering a carbon mesh and attaching an insulating film or a heat transfer plate to the upper surface.

  The fixing plate is an aluminum plate or a synthetic resin plate, and the edge frame is made of the same material. The edge frame is hollow and can be wired, and an end surface is provided with an uneven portion to facilitate fitting.

  According to this device, since the edge frame is fixed to the top, bottom, left, and right of the fixing plate of the heating panel, the heating panel can be firmly held, and the heating panel is made detachable by changing the front and back sides. You can select from one sheet to multiple sheets, and you can replace the front and back to install.Therefore, you can change the exposed surface when in use and when not in use to protect the heat generating surface of the electric panel and change the pattern. is there.

  In this device, the left and right edge frames are fixed to the left and right edges of the fixed plate with the edge frame to which the wired edge frames are fixed, respectively, and the electric heating panel is detachably attached to the inside of the fixed plate. Configured. From the outside, the electric heating panel has a decorative plate, a heat insulating plate made of synthetic resin foam, an electric heater, and an insulating heat transfer plate, which are sequentially layered and fixed. The electric heater is formed by, for example, applying carbon particles to an insulating film or board, or layering a carbon mesh, and can be an electric heater in which the upper limit of the heat generation temperature is regulated during manufacture. The above-described edge frame includes an edge frame including wiring and an edge frame not including wiring, which are appropriately used depending on the electric circuit. Further, the edge frame and the electric heating panel are energized by contact. Therefore, when the electric heating panel is fitted to the edge frame, the power is automatically supplied.

  The electric heating board can be fixed to the side wall or the side plate using a screw or an adhesive, but can also be fixed to the side wall or the side plate by other means (for example, using a pressing rod). In short, there are no restrictions on the fixed method. Next, the fixing of the electric heating panel and the fixing plate can be made detachable, for example, by fitting a latching protrusion provided on the edge frame of the fixing plate into a groove provided on the edge of the electric heating panel. it can.

  An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The hollow edge frames 2 and 2 are fixed on the upper and lower sides of a lattice-shaped fixing plate 1 made of synthetic resin to form a fixing plate with a frame. Two fixed plates are connected to form a fixed fixing plate, and the hollow edge frames 3 and 3 are fixed to the left and right sides thereof to form a fixed plate 4 with a frame, and the electric heating panels 5 and 5 are connected to the fixed plate 4 with the frame. The electric heating board 10 is formed by fitting and fixing.

  The connection between the hollow edge frames 2, 2 and 3, 3 is due to the fitting of the projection 6 of the contact portion and the recess 7, and the electric heating panels 5, 5 and the hollow edge frames 2, 2, 2 are connected. 3, 3 is fitted into the grooves 8, 8 provided on the side surfaces of the electric heating panels 5, 5 by fitting the removable rollers 9, 9 provided in the hollow edge frames 2, 2, 3, 3. Is. The rollers 9 and 9 are supported by the leaf springs 12 into the grooves 11 and 11, and by pressing the rollers 9 and 9, the leaf springs 12 are pressed down, and the leaf springs 12 are moved in the direction of the arrow 13. The heat generating panels 5 and 5 are pushed in such a manner that the upper surfaces of the rollers 9 and 9 are flush with the upper surface of the edge frame, and the rollers 9 and 9 are inserted into the grooves 8 and 8 of the electric heating panel. The panels 5 and 5 can be hooked and fixed. In the above embodiment, the roller 9 is used as the convex portion, but a frame body having an arcuate cross section can be used instead of the roller 9.

  An electric wire 14 is laid in the hollow portion of the edge frame, and the electric wire 14 and the contact pieces 15 and 15a come into contact with each other to complete the circuit. Therefore, if electricity is supplied from the power source via the cord 16, the electric heating panels 5 and 5 can be supplied with electricity to generate heat.

  That is, according to the present invention, as shown in the circuit 25 of FIG. 4, each of the heating panels 5 and 5 is connected in parallel to the power supply terminal 26, so that even if one heating panel is disconnected, Since the panel is energized, there is no risk of partial heat generation being interrupted by a partial failure. The amount of heat generated can be adjusted by the variable resistor 24.
