Description

Sensing device for a vehicle radiant heat heater and a vehicle radiant heat heater including the same {SENSING DEVICE OF RADIANT HEATER FOR VEHICLE AND RADIANT HEATER INCLUDING THE SENSING DEVICE} The present invention relates to a sensing device for a vehicle radiant heat heater and a vehicle radiant heat heater including the same, and more specifically, to a sensing device for a vehicle radiant heat heater and a vehicle radiant heat heater including the same, which can control the operation of the heater depending on whether there is a touch by configuring the structure to enable full touch by providing a capacitive touch sensor on the entire surface of the radiant heat heater. When using a vehicle, one must sit in a confined space for a long time, so if the temperature is not appropriate, one cannot maintain a comfortable riding condition. Therefore, automobiles are equipped with devices for cooling, heating, and ventilation. Generally, vehicle heating is achieved by utilizing the heat from the engine. Specifically, coolant that has absorbed engine heat is routed through a heater core installed within the air conditioning system. Air is then passed through the heater core to heat the air through heat exchange with the coolant, and heating is provided by supplying this heated air into the cabin. However, in the case of heating systems that utilize engine heat, heating does not occur until the engine is heated to a sufficient temperature because the coolant temperature is low. In other words, there was the inconvenience of no heating occurring during the initial stages of engine operation. Furthermore, since it is a method of supplying warm air, localized heating exclusively for individual passengers could not be implemented, and in the case of electric vehicles without engines, the above method of heating could not be fundamentally implemented. Therefore, a radiant heating element capable of generating heat using electricity, releasing the generated heat into the vehicle cabin in the form of radiant heat, and enabling localized heating was installed. Since the radiant heating element installed in the vehicle is mainly in the shape of a thin flat plate, it is also called a panel heater. These vehicle radiant heat heating elements were installed on the lower part of the dashboard in the vehicle interior, the steering column on the driver's side, the glove box on the passenger side, the backrest of the front seat, etc., and were installed on the back of the first row seats of the occupants so as to radiate radiant heat to each individual occupant. FIG. 1 is a schematic diagram showing an example of a conventional radiant heat heating element device for a vehicle, and FIG. 2 is a schematic diagram showing an embodiment in which a conventional radiant heat heating element device for a vehicle is installed in a vehicle. For example, a conventional radiant heater device (1) is installed on the lower surface of a steering column (13) connected to a steering wheel (14) of a vehicle driver's seat as shown in FIG. 1 to emit radiant heat toward the legs (12) of a passenger sitting in a seat (11), and the radiant heater device (1) is configured in a form in which a heat dissipation part (3), a heat generation part (4), and a terminal (7), etc. are formed on a substrate (2) as shown in FIG. 2. However, such radiant heat heating elements for vehicles are formed with a widely distributed heating element to suppress heat density concentration in order to prevent burns, so the structure is complex and difficult to manufacture, and there is also a problem that there is a risk of fire due to overheating caused by malfunction or abnormal operation. In addition, since the radiant heat heating element is installed in a location close to the occupant's body, there is a high risk of burns from contact. Therefore, to prevent burns, the surface temperature of the heater is typically controlled to a level of 70°C or lower. However, since there is not much heat radiated from the surface at about 70°C, it takes a long time to feel the heating even after the heater is started, and the heating intensity is weak, so there was a problem with the overall heating performance being poor. Meanwhile, conventional radiant heat heaters use a temperature sensor as a means to detect the temperature of the heater to control the temperature of the heater, and additionally use a secondary safety device such as a bimetal. The on/off operation and temperature control of such radiant heat heaters are controlled by a simple method in which the user operates an on/off switch and a temperature control switch on a switch panel located around the heater. However, the aforementioned detection sensor is attached to a specific part of the heater, and thus has the problem of not being able to detect localized overheating or malfunctions. In addition, if the detection sensor becomes detached from the heater or operates abnormally, an inaccurate temperature is det
