ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electric heater generally used for heating a space in a building, and more particularly, to an improvement to the electric heater of the Korean Utility Model Application No. 1997-5769 of the same inventor as that of the present invention.
2. Description of the Prior Art
An electric heater disclosed in the Korean Utility Model Appln. No. 97-5769 is designed to radiate heat generated from an electric heating wire a long way off by using a spherical reflector (for example, a parabolic type), thereby obtaining an optimal energy efficiency.
The reflector of the electric heater, however, is permanently fastened at a post on a stand and thus a user must reach or get to the heater and manually change the direction to which the reflector faces, whenever the user wants to change the direction of the heat radiation.
Moreover, the heater could hardly warn a room or space uniformly in a short period of time, if it were left to radiate heat only in one direction.
SUMMARY OF THE INVENTION
It is an object of this invention to provide an electric heater which can warm a space uniformly in a relatively short period of time.
Another object of this invention is to provide an electric heater which is very convenient and simple to use.
The above objects can be accomplished by providing an electric heater which can alternately change the lateral direction of the heat radiation from left to right and then from right to left by means of a reflector rotating device.
The present invention provides an electric heater with a post and a heating member; which comprises an orientation device comprising a pole or spindle fixed on the post; a movable plate formed with front and rear holes and rotatably mounted on the pole or spindle through the front hole, carrying the heating member; a geared motor with a shaft extending downwardly through the rear hole of the movable plate; a transmission plate formed with mating teeth on the upper surface and rotatably fixed to the lower end of the motor shaft; a driving plate carrying a guide pin on or near its lower edge and formed with mating teeth in a groove on its bottom surface to be engaged with the counter part of the transmission plate; a spring mounted around the motor shaft under the movable plate for elastically pressing the driving plate downwardly; and an elongate guide path formed on the post for receiving the guide pin obliquely relative to the pole or spindle and allowing it to reciprocate straightly therein.
Therefore, when a user turns on a switch of the rotating device, the reflector performs a continuous reciprocating motion in an adequate speed within the range of the predetermined angle, thereby radiating heat generated from the heating wire uniformly within a room or space to be heated or warmed.
