Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to an electric heater in which a plurality of heaters are arranged in tandem and heating is performed by the hot wires of the plurality of heaters.

<Prior art> Conventionally, in an electric heater in which a plurality of heaters are arranged in a column (in series in the vertical direction) and heating is performed by the hot wires of the plurality of heaters, heating is performed only by the hot wires of the plurality of heaters. As a result, heating becomes irritating and a comfortable heating condition cannot be obtained.

<Purpose of the invention> The object of the invention is to obtain an electric heater that eliminates the above-mentioned drawbacks.

<Embodiment of the invention> Hereinafter, an embodiment of the electric heater of the invention will be described with reference to FIGS. 1 and 2 in the case where it is implemented in an electric heater having two heaters arranged in tandem.

In the electric heater of the present invention, a first heater 2 as an upper heater and a second heater 3 as a lower heater are arranged in a vertical line in a heater main body 1, and the second heater 2 is located behind the first heater 2. A parabolic first reflecting plate 4 that reflects the heat rays of the first heater 2 forward is disposed on the heater main body 1, and is located behind the second heater 3 to reflect the heat rays of the second heater 3 forward. A parabolic second reflection plate 5 is disposed on the heater main body 1, and a first guard 6, which is located in front of the first heater 2 and prevents contact with the first heater 2, is disposed on the heater main body 1. 1 and the second heater 3
A second guard 7 is disposed in front of the heater body 1 to prevent contact with the second heater 3, and is located between the first heater 2 and the second heater 3 to protect the warm air from the front A suction passage 9 having a suction opening 8 for sucking the air is provided in the heater main body 1, and warm air is sucked in through the suction passage 9, and the warm air is sent to the air outlet located at the upper end of the first heater 2 through an air blowing passage 10. A blower 14 comprising a fan 12 and a fan motor 13 for blowing air from a fan 11 is provided on the heater main body 1, and the heater main body 1 is supported by a stand 15.

In FIGS. 1 and 2, reference numeral 16 denotes a power switch that turns on and off electricity to the first heater 2, second heater 3, and fan motor 13 of the blower 14; It is provided on the upper surface of the main body 1.

Next, the usage conditions of the electric heater configured as described above will be explained.

Now, when the power switch 16 is turned on and the first heater 2, second heater 3, and fan motor 13 of the blower 14 are energized, the first heater 2 and the second heater 3 generate heat, and the first heater 2 The heat rays are directly or reflected by the first reflector 4 and radiated forward, and the heat rays of the second heater 3 are radiated forward directly or reflected by the second reflector 5, and the heat rays from the first heater 2 and the second heater 3 are radiated forward. Heating is performed by two heaters 3. In this case, warm air heated by the second heater 3 is obtained above the second heater 3 (near the air inlet 8), and the warm air is passed through the air inlet 8 and the suction passage 9 by the fan 12 of the blower 14. The air is sucked in and blown out forward through the air blowing path 10 and the air outlet 11, and heating with hot air is performed at the same time.
In addition, since the warm air above the second heater 3 is sucked in through the suction port 8, the second heater 3 is no longer heated toward the front of the first heater 2, and the heating temperature increases upward. Never.

Note that in the above embodiment, the air outlet 11 is
Although the case where the outlet 11 is provided at the upper end of the heater 2 has been described, the outlet 11 may be located at the lower end of the second heater 3 and the outlet 11 may be provided with an air passage 10 for blowing air. In the example, a case was explained in which the method was applied to an electric heater in which two heaters were arranged in tandem, but a case in which the method was applied in an electric heater in which three or more heaters were arranged in tandem was explained. However, the present invention is not limited to the above-mentioned embodiments, and can also be applied to an electric heater in which three or more heaters are arranged in series.

<Effects of the invention> The electric heater of the invention uses warm air that is heated by the lower heater of the plurality of heaters and rises from the suction port between the heaters of the plurality of heaters arranged in tandem by the operation of the blower. The warm air is blown from the upper outlet of the upper heater of the plurality of heaters to the front of the heater along with the warm air that is warmed by the upper heater and rises, so that the air is blown by the blower. The temperature of the warm air is high, so the user does not feel cold due to the air flow, and the warm air heated by the upper heater can be efficiently blown forward without escaping upward, and the above-mentioned multiple Even if the book heaters are arranged in a column, the heating temperature does not become extremely high as the book heaters move upward, and a comfortable heating condition can be obtained.
