ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a radiant heater with a halogen lamp used to increase room temperature in the winter season, and more particularly to a radiant heater in which a halogen lamp is mounted in the front of the heater, so that a large amount of heat is radiated in a short period of time, thereby being capable of maintaining an optimum room temperature.
2. Description of the Prior Art
As well known to those skilled in the art, in order to maintain a room at an optimum temperature, a variety of heating apparatus have been proposed. These heating apparatus employ liquid or gaseous fuel, and increase room temperature to an optimum value and maintain the optimum room temperature using heat emitted during the combustion of the fuel.
However, in the case of utilizing such liquid or gaseous fuel, combustion gas generated during the combustion of such fuel causes room air to be contaminated and does harm to a user. Accordingly, the user has to frequently ventilate the room by opening a window, which causes a room to be deprived of heat, thus resulting in waste of fuel.
In order to overcome the shortcoming of the conventional heating apparatus, there has been developed another type of heating apparatus with heating wires that convert electrical energy, instead of liquid or gaseous energy, to thermal energy. However, in this type of apparatus, excessive electricity consumption occurs in the heating wires, to impose a heavy economic burden on the user.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a radiant heater with a halogen lamp in which a halogen lamp, which emits a large amount of far infrared radiation while consuming a relatively small amount of electricity, thereby emitting a large amount of heat in a short period of time and therefore maintaining a room at an optimum temperature.
In order to accomplish the above object, the present invention provides a radiant heater with a halogen lamp, comprising: a base connected to a power supply cord, the base being provided with an oscillation control switch, a timer control switch and a temperature control switch; a power shut-off switch mounted on the bottom of the base, the power shut-off switch allowing electricity to be applied to the heater when the bottom of the base is in full contact with a floor; a support column stood on the top of the base and provided with a height control button at its upper portion; a retractable rod inserted into the support column and supported by a spring disposed on a spring holder; a neck rotatably connected to the upper end of the retractable rod; a head fixed to the top of the neck, the head including a reversible motor; an operating rod fixed to the upper portion of the neck at its one end and rotatably connected to the rotating shaft of the reversible motor; a support projection mounted on the front of the head; a reflector and a reflector cover fixed between the head and the support projection, the reflector and the reflector cover being spaced apart from each other; a lamp cover fixed to the front of the support projection for distributing far infrared rays to the reflector and preventing the eyes of a user from being dazzled; a halogen lamp spaced inwardly somewhat apart from the lamp cover, the halogen lamp being supported by a lamp holder fixed to the support projection at its one end and radially arranged; and a protective grill clamped together with the reflector and the reflector cover by clamping means.
