Description

  The present invention is a technique for fixing a heat generating panel to a wall surface. The heat generating panel can be freely fixed to an existing wall surface or a new wall surface, and the heat generating panel can be fixed easily. The present invention relates to a panel installation device, a heat generating panel fixing member, and a heat generating panel.

  Conventionally, there have been proposals for floor panels, heated floors, heated tatami mats, and the like as uses of electric heating sheets. The floor panels have been put into practical use and are expected to spread in the future.

The electrical heating sheet is connected to a conductive sheet coated or printed with a carbon paint mainly composed of carbon powder on an insulating film, and the carbon powder is heated red to generate far infrared rays when energized. Due to the characteristics of the carbon powder, it is possible to automatically control the output by increasing the resistance due to temperature rise, so instead of the conventionally known nichrome heating wire, it is highly likely that the practical application range will be expanded in the future. Is done.

  Since the conventional floor heating has a thin heat generating sheet, there is an advantage that it can be used as a heat generating material for floor heating while maintaining the properties and dimensions of the conventional floor material. Therefore, the heat generating material is used by sandwiching the heat generating sheet between a heat insulating panel and a protective panel and laying it under the floor board.

  In addition, the patent applicant previously invented heating inside the counter by sticking a heat generating panel to the counter's waist plate, but for the fixing device, a consistent mounting structure has not yet been developed, which is a research subject. It was.

Therefore, if the heat generating panel 50 is fixed at an appropriate position of the counter, it can be kept warm as a predetermined heater.

  The heat generating panel is usually fixed to the lower part and the vertical wall of the top plate of the counter, but the long glass fiber cloth 55 can have an appropriate design view if it has a color, a pattern, or a combination thereof.

  In the above-described embodiment, the base plate 51 is used. However, if a material for strength and heat insulation is used for the heat insulating board 52 (for example, a laminated plate of a foamed resin plate and a plywood of an organic plate or an inorganic plate). ) The base plate 51 can be omitted. Further, if the design such as the color and pattern of the fiber reinforced cement board 54 is taken into consideration, the glass fiber cloth can be omitted.
