Description

High safety heater which can detect subject heat {

The present invention relates to a high-safety heater capable of detecting a subject's heat, and installs a thermopile sensor on the front of the housing to recognize when the user's clothes are heated to deform so that the heater lamp is blocked to prevent it, and the heat of the heater lamp is prevented. A heat collecting duct functioning as a duct in the center of the front surface of the rear reflector reflecting the light, and a narrow front heat collecting auxiliary plate in the front of the heater lamp to increase the heat exchange rate in the heat collecting duct to prevent overheating without operating the suction fan. The goal is to provide as high a safety heater as possible.

In general, the infrared sensor is a non-contact temperature measuring method, and has been used in a case where contact is virtually impossible due to a rotating measurement object or a high temperature.

In addition, such infrared sensors, which are used in various electronic devices that sense specific objects and cause operation as predetermined signals, include photovoltaic effedt or photonic type sensors using photoconductive effects. And thermal type sensors such as bolometers, pyroelectric sensors, and thermopile sensors.

The quantum sensor uses incident radiation to excite electrons to change the electrical characteristics of the sensor. In general, the quantum sensor has excellent sensing performance and fast response in a selected wavelength range.

However, related manufacturing techniques have not yet been established, it is expensive, there is a disadvantage to operate in a cryogenic state in the liquid nitrogen (liquid-N 2) temperature range in order to obtain a predetermined infrared sensitivity.

Therefore, in order to use the infrared sensor in the industry, there is a need for a device that does not require cooling, and is inexpensive and reliable.

A thermopile sensor that can compensate for this drawback is to form a structure in which different materials of different kinds make a contact on one side and an open side on the other side. It refers to a sensor that senses temperature by using the Seebeck effect that thermo electric power occurs in proportion to the size of.

This thermopile sensor has a stable response to DC radiation, responds to a wide infrared spectrum, and does not require bias voltage or bias current.

The principle of operation of the thermopile sensor is based on Stefan-Boltzmann's law, which states that "all objects radiate energy from the surface proportional to the fourth power of absolute temperature."

That is, if the absolute temperature of the object is T, the energy radiated from the object is P, and the emissivity is ε, then P∝εσT 4.

Is the Stefan-Boltzmann constant (5.67 x 10 -8 Wm -2 K -4).

As a result, the thermopile sensor detects energy proportional to T 4 and measures the temperature. As shown in FIG. 1, the energy incident on the thermopile sensor 1 is the energy radiated from the measurement object 2 ( A), the energy generated by the temperature around the measurement object 2 is reflected by the measurement object 2, the energy (B) incident on the thermopile sensor 1, the sensor package by the temperature around the sensor package (3) Energy (C) radiated from the cap of (3) and incident on the thermopile sensor (1), heat conduction (D) through the sensor package (3), and energy (E) radiated from the thermopile sensor (1) itself, and the like. There is this.

In general, a heater includes a ceramic heater in which a spring heating element or a shizu heater is embedded in a ceramic body, a heater in which reflectors are installed in the front and rear of a heater lamp such as a halogen lamp or a carbon lamp in which a heating element is installed in a vacuum glass tube, and an outside air heater. Hot air heaters are known, in which air is sucked in and passed through a heating element of a heater to exhaust outside air for heating.

The control unit 54 is also installed in the front of the housing (5) and connected to receive a sensing value from the thermopile sensor 60 for sensing the heat of the subject.

The present invention configured as described above has the same basic function of reflecting light and heat through the heater lamp (1) from the rear reflector (2) to be supplied to the front,

In addition, the present invention heats the heat collecting duct 10 installed in the center front of the rear reflector 2 with the light and heat of the heater lamp 1, and the heated heat heats the suction outside air through the duct hole 12 Function to discharge. Therefore, while the suction outside air through the suction fan 30 passes through the duct hole 12 from the bottom surface, it is heated by instant heat exchange with warmth.
