It is composed of the discharge unit 18, and the deodorization catalytic filter unit 17, the second sensor unit 19 to components of the odor gas saturation at the time of gas components adsorbed odor deodorizing catalyst filter unit 17 in which.

7 is a circuit diagram of the deodorizing catalyst filter regeneration device of the air conditioner of the present invention, wherein the output voltage and resistance (R2) of the second sensor 19A for detecting the saturation state of the odor gas component adsorbed on the deodorizing catalyst filter unit 17 ( The comparison unit 26 for comparing the reference voltage Vref set by R3, the comparison signal of the comparison unit 26 and the output voltage of the first sensor 14A are received, and after deciding, the deodorization catalyst filter unit ( 17 turns on the microcomputer 27 for controlling the odor gas component adsorbed on the oxidizing gas and the relay RLY of the heater control unit 30 for controlling the driving of the heater 22 according to the control signal of the microcomputer 27. A switching means Q1 for turning on / off and a relay RLY for controlling the heater 22 according to the on / off signal of the switching means Q1. Reference numerals R1, R4, and R5 denote resistors, C1. Silver capacitor, L1 is a coil, SW1 is a switch, and the said switching means Q1 was comprised by the relay drive transistor.

The operation and effect of the present invention configured as described above is shown in FIGS. 2 to 7, when the air conditioner is driven to purify indoor air containing dust and odor gas components, the first sensor unit 14 is the suction unit. Detecting the concentration of the odor gas component contained in the indoor air sucked through the (11), the filter unit 12 removes large dust in the sucked indoor air and passes through.

At this time, the electrostatic precipitator 13 removes the small dust particles from the indoor air passed through the large dust is removed from the filter unit 12, the blower fan 16 is the air from which the dust passed from the electrostatic precipitator 13 is removed Moves to the discharge part 18 side.

When the dust is removed and the air containing the odor gas component is moved toward the discharge portion 18, the adsorption portion 21 coated on the adsorption plate 20 for widening the adsorption surface area in the deodorization catalyst filter portion 17 is provided with the odor gas component. Is adsorbed and passed through.

When the odor gas component is adsorbed by the deodorization catalyst filter unit 17, the second sensor unit 19 senses the saturation state of the odor gas component adsorbed by the deodorization catalyst filter unit 17.

When the first sensor unit 14 and the second sensor unit 19 detect a large output value of the odor gas component, the output voltage increases as shown in FIG.

That is, when the user drives the air conditioner, the concentration of the indoor odor component gas detected by the first sensor unit 14 after a predetermined time elapses (section A) is high and the first sensor unit 14 as shown in FIG. The output voltage of the microcomputer is high and the saturation state of the odor gas component adsorbed on the deodorization catalyst filter unit 17 detected by the second sensor unit 19 is lower than the reference voltage set as shown in (b) of FIG. 9. Numeral 27 determines that the odor gas component can be continuously adsorbed by the deodorization catalyst filter unit 17.

Thereafter, when a predetermined time has elapsed (section B), as shown in (a) of FIG. 9, the second sensor unit 19 may be configured even if the concentration of the indoor odor gas component detected by the first sensor unit 14 is low, so that the output voltage is low. As shown in (b) of FIG. 9, if the saturation state of the odor gas component adsorbed on the deodorization catalyst filter unit 17 is greater than the set reference voltage, the microcomputer 27 does not adsorb the odor gas component in the indoor air. I do not think.

Therefore, when the microcomputer 27 inputs a high signal to the base of the switching transistor Q1 of the heater control unit 30 through the output terminal, the switching transistor Q1 is turned on so that current flows in the coil L1 in the relay RRY. The switch contacts the switch SW1 from NO terminal to NC terminal.

As such, the relay RLY is driven so that power is applied to the heater 22 through the power connection unit 23, so that heat is generated to the adsorption unit 21 coated on the adsorption plate 20 wrapped in the heater 22. Since the heat is transferred and the odor gas component adsorbed on the adsorption unit 21 is oxidatively decomposed, the deodorization catalyst filter unit 17 is regenerated, thereby allowing the odor gas component contained in the indoor air to be adsorbed again.

And the suction plate 20 wrapped in the heater 22 can be disassembled and coupled as necessary through the screw hole 24 formed in the suction plate 20 by the user.

Meanwhile, as another embodiment of the present invention, the saturation state of the odor gas component adsorbed on the deodorization catalyst filter unit 17 is determined using only one sensor unit 14 that detects the concentration of the odor gas component included in the indoor air. As shown in FIG. 10, the microcomputer 27A which receives the odor gas component contained in the indoor air detected by the sensor unit 14 and determines the concentration of the current indoor odor gas component, and the indoor odor gas The deodorization catalyst filter unit calculates the time data in which the odor gas component is saturated in the deodorization catalyst filter unit 17 according to the concentration of the component and the time in the odor gas component that changes according to the voltage value detected by the sensor unit 14. A calculation unit 28 for determining whether 17 is saturated, a display unit 29 for displaying the concentration of odor gas components contained in the indoor air, and a deodorization catalyst when the deodorization catalyst filter unit 17 is saturated. filter The heater control unit 30 is configured to control the heater 22 by the control signal of the microcomputer 27A so that the odor gas component adsorbed on the unit 17 is oxidized and decomposed. The display unit 29 displays the concentration of the odor gas component contained in the indoor air.

At this time, as shown in FIG. 11 in the microcomputer 27A, when the concentration of the odor gas component is small (small), the time when the odor gas component is saturated in the deodorizing catalyst filter unit 17 is long (T1), and the odor gas When the concentration of the component is medium (medium), the time when the odor gas component is saturated is medium (T2), and when the concentration of the odor gas component is large (large), the time when the odor gas component is saturated is short (T3) Is stored.

Therefore, the microcomputer 27A determines whether the concentration of the odor gas component included in the indoor air detected by the sensor unit 14 is small, medium or large, and deodorizing catalyst filter unit according to the determined concentration of the odor gas component ( When the calculation unit 28 calculates the time for which 17 is saturated and applies it to the microcomputer 27A, the microcomputer 27A determines whether the deodorizing catalyst filter unit 17 is saturated.

If it is determined that the odor gas component adsorbed on the deodorizing catalyst filter 17 is saturated, the heater controller 30 operates the heater 22 according to the control signal of the microcomputer 27A to adsorb the deodorizing catalyst filter 17. The odor gas component is oxidized and decomposed so that the odor gas component continues to be adsorbed by the deodorization catalyst filter unit 17.

As described above, the heater is automatically heated and adsorbed to the deodorization catalyst filter when the odor component is adsorbed to the deodorization catalyst filter that removes the odor component while driving the air conditioner for a certain period of time to purify the indoor air. The odor component is oxidatively decomposed so that the odor component adsorbed on the deodorizing catalyst filter part is prevented from being diverted to the room while removing the odor gas component contained in the indoor air, thereby improving the reliability of the product.
