Description

Carbon hot air blower {CARBON HEATING AIR BLOWER APPARATUS}

The present invention relates to a carbon hot air blower device, and more particularly, it is possible to use a carbon heating element containing carbon fiber to heat a blower stream with heat and far infrared rays, so that it can be used comfortably even in a closed room and can be used for a long time. It relates to a carbon hot air blower device that does not cause discomfort to the eyes and can significantly reduce power consumption compared to the existing coil heating method.

In general, a heater mainly used in cold weather in winter is to protect the human body or crops from cold air. Conventionally, a combustion stove using combustion heat generated by burning fuel such as oil or gas or electric energy is converted into thermal energy. There are electric heaters that generate heat.

Here, in the case of the conventional combustion stove, the fuel price is high, the maintenance cost is excessive, and the fuel needs to be periodically replenished. It has a negative effect on crops, and there was a problem that it had to be ventilated periodically.

In addition, in the case of an electric heater, it generates heat quickly and has a relatively simple structure and is easy to operate, so it is used for indoor heating in homes and offices, whereas heat is transmitted only in front or around the heater, so it is limited to local heating and the heating efficiency is significantly reduced. Of course, overload or sparks frequently occur, and there is a very high risk of safety accidents such as fire and burns due to this, and there is a problem that requires special attention when using. In addition, when the hot air is discharged by blowing wind on a heating element such as a resistance coil using a blower fan, the heating range can be increased, but there is a problem in that the wind of the blowing fan rubs against the resistance coil, resulting in a large noise.

However, in the case of the conventional power supply unit, in order to convert the input DC power into a form of power capable of driving the heating element 10 , the electronic components such as each element configured in the power supply unit 40 are the heating element 10 . Since the circuit is designed to optimize efficiency in the rated output state, when the user reduces the brightness of the heating element 10, the size of the driving power supplied to the heating element 10 is reduced compared to when the driving power is supplied to the maximum. The power factor decreases and electrical characteristics such as EMI become incomplete.

Therefore, even if the user operates the input unit 60 to reduce the temperature of the heating element 10 to 50% in order to reduce power consumption by 50% in a state in which the heating element 10 is rated output and is the highest temperature, the electrical characteristics as described above As the power consumption is consumed more than 70% due to the incompleteness of

The switching unit 182 is a component that performs a switching operation so that DC power selectively rectified is supplied to each group power supply unit 181 according to a control signal output from the power control unit 183, and the rectifying unit 185 is Each group power supply unit 181 and the rectifier unit 185 are arranged on an interconnected electrical connection line so that the DC power rectified by the power is independently applied to each group power supply unit 181, and according to the control signal, the It operates to cut off the DC power to the group power supply unit 181 by shorting the electrical connection line, or to supply the DC power from the rectifier unit 185 to the group power supply unit 181 by contacting the electrical connection line. That is, the switching unit 182 functions to selectively supply rectified DC power to all of the group power supply units 181 or some of the group power supply units 181 .

The power control unit 183 is composed of a control IC or the like, and outputs a control signal to the switching unit 182 so that the heating plate 130 generates heat at a predetermined temperature according to an input signal.

Here, when the group power supply unit 181 to which the input power is not transmitted is generated according to the input signal of the input unit 170 and the magnitude of each driving power converted by each group power supply unit 181 is the same, the power supply It is preferable that the control unit 183 controls the switching unit 182 so that the input power is not transmitted to each group power supply unit 181 in a set sequence.

For example, when two group power supply units 181 are configured as shown in FIG. 8 , when the user wants to use at a temperature of 50% of the rated output temperature according to the user's selection, the input unit 170 receives an input signal according to the user's operation. of the two group power supply units 181, one of the group power supply units 181 must be supplied with the DC power and the other group power supply unit 181 with the DC power not transmitted to the switching unit 182. ) is a switching operation, at this time, if the group power supply unit 181 to which the DC power is not transmitted is fixed and determined, the group power supply unit 181 to which the DC power is transmitted whenever the temperature is controlled to 50% is converted and driven If not, the lifespan is shortened, and the group power supply unit 181 to which the DC power is not transmitted has a relatively long lifespan.

Therefore, it is possible to minimize the difference in the driving time of each group power supply unit 181 by switching control so that DC power is not evenly transmitted to each group power supply unit 181 in a predetermined sequence as described above. It is possible to increase the overall lifespan of (181).

In addition, each heating plate 130 is grouped into a number of groups corresponding to the number of each group power supply unit 181 , and the heating plates 130 belonging to the same group are connected to the same power supply line, and each group power supply unit 181 . is preferably connected to each power supply line individually to apply driving power.

For example, as shown in FIG. 9, when the group power supply unit 181 is composed of two, the heating plate 130a, 130c, 130e, 130g, 130i, 130k belonging to the first group has the first group power supply unit 181a. ) is grouped, and the heating plates 130b, 130d, 130f, 130h, 130j, and 130l belonging to the second group may be grouped in the second group power supply unit 181 .

Therefore, when input power is transmitted to the first group power supply unit 181a, the heating plates 130a, 130c, 130e, 130g, 130i, and 130k of the first group are driven with heat, and the input power supply to the second group power supply unit 181b When this is transmitted, the heating plates 130b, 130d, 130f, 130h, 130j, and 130l of the second group are driven by heat, and accordingly, the heating temperature is lowered, so that even if only some heating plates 130 are driven, they are discharged through the hot air exhaust hole 112. The hot air flow to be used can be blown at a uniform temperature as a whole.

As described above, although the present invention has been described with reference to limited embodiments and drawings, the present invention is not limited thereto, and the technical spirit of the present invention and the following by those of ordinary skill in the art to which the present invention pertains. It goes without saying that various modifications and variations are possible within the scope of equivalents of the claims to be described.
