Title:
HEATER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/198413
Kind Code:
A1
Abstract:
A heater device (1) that comprises an insulating substrate (10), a heat generation part (20), a transmission electrode (30), a reception electrode (40), a detection circuit (71), and a control device (70). The insulating substrate (10) is tabular. The heat generation part (20) is provided on one surface of the insulating substrate (10) and generates heat as a result of being energized. The transmission electrode (30) and the reception electrode (40) are provided on the insulating substrate (10) on the surface on which the heat generation part (20) is provided. On the basis of changes in the electrostatic capacity between the transmission electrode (30) and the reception electrode (40), the detection circuit (71) detects the approach of or contact by objects. When the detection circuit (71) has detected the approach of or contact by an object, the control device (70) reduces the energization of the heat generation part (20) to below a normal state or suspends the energization. The transmission electrode (30) and the reception electrode (40) are arranged so as to have a heat-dissipation function that causes heat that has been generated by the heat generation part (20) to be diffused in the planar direction.
