In addition, by providing a plurality of deodorizing

filters

300 and 500, it is possible to more effectively adsorb and remove malodorous substances in the air.

The ultraviolet irradiation unit 400 is located at the rear end of the first deodorizing filter 300 , specifically, between the first deodorizing filter 300 and the second deodorizing filter 500 .

The UV-A irradiator 411 and the UV-C irradiator 412 are composed of a light emitting diode (LED) or a lamp that generates ultraviolet ray to irradiate ultraviolet ray, but is not limited thereto and may be configured to generate ultraviolet ray.

Ultraviolet light has a shorter wavelength than visible light, and its wavelength range is approximately 10 to 400 nm, and within this wavelength range, it can be further divided into UV-A, UV-B, and UV-C.

Among them, the UV-A irradiation unit 411 irradiates UV-A. UV-A is an ultraviolet light having a wavelength range of approximately 320 to 400 nm, and when irradiated to titanium dioxide on the surface of the activated carbon of the first deodorization filter 300 and the second deodorization filter 500, a catalytic reaction occurs, such a catalytic reaction Odor substances adsorbed to the activated carbon are oxidized and removed.

The control unit 101 is connected to each of the

sensors

801, 802, 803, 804, 805, the UV-A irradiator 411, the UV-C irradiator 412 and the fan 600, and each sensor ( Receives values sensed from 801 , 802 , 803 , 804 , and 805 , and controls the operation of the UV-A irradiator 411 , the UV-C irradiator 412 , and the fan 600 .

In addition, a display unit 102 and an operation unit 103 connected to the control unit 101 are provided.

The display unit 102 is composed of a plurality of LEDs or a means that the user can visually check, such as a display device.

The manipulation unit 103 may include a plurality of function manipulation buttons, a touch panel, and the like.

As the user operates the manipulation unit 103 , the control unit 101 controls the operations of the UV-A irradiator 411 , the UV-C irradiator 412 , and the fan 600 , and the UV-A irradiator 411 , UV -C The operating states of the irradiation unit 412 and the fan 600 are displayed on the display unit 102 .

On the other hand, the control unit 101 controls the operation of the UV-A irradiator 411, the UV-C irradiator 412 and the fan 600 in a preset operation mode, or is connected to each of the sensors to be detected by each sensor. Operations of the UV-A irradiator 411 , the UV-C irradiator 412 , and the fan 600 may be controlled according to the odor concentration, which will be described later.

In addition, a pre-treatment filter 150 may be further provided between the suction port 111 and the dehumidifying filter.

The pretreatment filter 150 removes particulate matter, such as dust, contained in the incoming air. The pre-treatment filter 150 may be configured as a filtration type filter that removes particulate matter.

Next, with reference to the accompanying Figures 1 to 3 again, the operation of the deodorizing device according to an embodiment of the present invention will be described in detail.

First, the fan 600 operates so that air outside the housing 100 is introduced into the housing 100 through the suction port 111 , and the UV-A irradiator 411 and the UV-C irradiator of the UV irradiator 400 . UV-A and UV-C are respectively irradiated from (412).

At this time, the odor concentration of the air introduced into the housing 100 is sensed in real time by the inflow sensor 801 .

The introduced air passes through the pre-treatment filter 150 to remove particulate matter such as dust.

The air from which the particulate matter has been removed flows into the dehumidifying filter 200 , and moisture contained in the air is absorbed and removed by the desiccant of the dehumidifying filter 200 .

As described above, by removing particulate matter and moisture from the incoming air in advance, damage to the first deodorizing filter 300 and the second deodorizing filter 500 made of activated carbon or deterioration of adsorption capacity of odor substances is prevented.

Air from which particulate matter and moisture has been removed flows into the first deodorizing filter 300, and the malodorous material is adsorbed to the micropores formed in the activated carbon and is first removed, and through the ventilation slit 420 of the ultraviolet irradiation unit 400 It is introduced into the second deodorization filter (500).

At this time, the air flowing from the first deodorizing filter 300 to the second deodorizing filter 500 is irradiated with UV-C from the UV-C irradiator 412 , thereby killing bacteria or viruses contained in the air.

In addition, when UV-A is irradiated to the first deodorizing filter 300 and the second deodorizing filter 500 , the odor substances adsorbed to the activated carbon are oxidized and removed by the photocatalytic reaction of titanium dioxide. Accordingly, the adsorption function of the first deodorizing filter 300 and the second deodorizing filter 500 is partially regenerated.

In addition, the odor concentration of the air flowing from the first deodorizing filter 300 to the second deodorizing filter 500 is sensed in real time by the intermediate sensor 803 .

The odor substances of the air introduced into the second deodorization filter 500 are adsorbed to the micropores formed in the activated carbon and are removed secondarily, and the air that has passed through the second deodorization filter 500 passes through the fan 600 and passes through the outlet 121 . The odor concentration of the air flowing out to the outside of the housing 100 through the outlet 121 and flowing out to the outside of the housing 100 through the outlet 121 is detected in real time by the outflow sensor 802 .

Manual mode and automatic mode will be described. The manual mode is a mode in which the above operation is performed by a user's manipulation, and the automatic mode is a mode in which the above operation is automatically performed by the control unit 101 .

In the manual mode, the user manipulates the manipulation unit 103 to adjust the output intensity of the fan 600 and the UV-A and UV-C output intensity irradiated from the ultraviolet irradiation unit 400 .

In the automatic mode, the output intensity of the fan 600 and UV-A and UV irradiated from the ultraviolet irradiation unit 400 according to the odor concentration of the air flowing into the inlet 111 detected by the inlet sensor 801 as described above. This is done by adjusting the output intensity of -C.

For example, the control unit 101 sets the range of odor concentration as low concentration, medium concentration, and high concentration, respectively, as a first set value, a second set value, and a third set value, and is detected by the inflow sensor 801 The output of the UV-A irradiator 411 and the UV-C irradiator 412 is switched to low power, medium power, and high power according to which range of the odor concentration is within the respective set values.

Accordingly, it is possible to reduce the power consumption of the ultraviolet irradiation unit 400 and the fan 600 and to quickly reduce the odor gas.

In addition, during the operation of the deodorizing device, when the difference between the odor concentration of the air detected by the inflow sensor 801 and the odor concentration of the exhaust air detected by the outflow sensor 802 is less than a preset value, the display unit Display the replacement signal of each deodorizing filter (300, 500) at (102).

That is, in this case, the malodorous substances contained in the air flowing into the inlet 111 are not properly adsorbed through each

deodorizing filter

300 and 500. By displaying the replacement signal of each deodorizing filter (300, 500) through the display unit (102) informs the user that the replacement of each deodorizing filter (300, 500) is required.

And, when the difference between the odor concentration detected by the inflow sensor 801 and the odor concentration of the air detected by the intermediate sensor 803 is less than a preset value, the control unit 101 receives the rotation signal of the first deodorization filter 300 displayed on the display unit 102 .

In this case, as the first deodorizing filter 300 positioned between the inflow sensor 801 and the intermediate sensor 803 does not properly adsorb odor substances, the control unit 101 controls the first deodorization filter ( 300) rotation is required.

In addition, when the difference between the odor concentration detected by the intermediate sensor 803 and the odor concentration of the air detected by the outflow sensor 802 is equal to or greater than a preset value, the control unit 101 receives the rotation signal of the second deodorization filter 500 . displayed on the display unit 102 .

In this case, as the adsorption of odor substances is not performed properly through the second deodorization filter 500 located between the intermediate sensor 803 and the inflow sensor 801, the control unit 101 controls the second deodorization filter ( 500) rotation is required.

In the above case, the first deodorizing filter 300 or the second deodorizing filter 500 may be replaced to restore the adsorption capacity of odor substances, but the first deodorizing filter 300 and the second deodorizing filter 500 are UV The surface opposite to the -A irradiation unit 411 has a relatively small decrease in adsorption capacity by UV-A irradiated from the UV-A irradiation unit 411 .

Therefore, without replacing each deodorizing filter (300, 500) with a new deodorizing filter, the opposite side of each deodorizing filter (300, 500) is rotated to face the ultraviolet irradiation unit 400 and remounted to restore the adsorption capacity. , In such a case, the control unit 101 may display the rotation signals of the first deodorizing filter 300 and the second deodorizing filter 500 on the display unit 102 .

In this way, by rotating and re-installing the deodorizing filter, the adsorption capacity of each

deodorizing filter

300 and 500 is restored, and the surface with the reduced adsorption capacity is regenerated by UV-A.

In the case of a general, deodorizing device, the filter replacement cycle is displayed when a predetermined operating time has been accumulated.

According to the present invention, it is possible to accurately determine the replacement or rotation time of the deodorizing filter based on the value of the actual odor concentration rather than the accumulated operating time, thereby reducing the burden of replacement and maintenance cost of the filter.

In addition, there is an advantage that it is possible to continuously extend the life of the activated carbon through a photocatalyst by irradiating UV-A to each deodorizing filter (300, 500).

When the difference between the humidity detected by the humidity sensor 805 located at the front of the dehumidifying filter and the humidity detected by the humidity sensor 805 located at the rear of the dehumidifying filter is less than a preset value, the control unit 101 displays the dehumidifying filter on the display unit 102. (200) By displaying a replacement signal to replace the dehumidifying filter 200, each

deodorizing filter

300, 500 is prevented from being damaged due to the performance degradation of the dehumidifying filter 200.

And, when the temperature sensed by the temperature sensor 805 is equal to or greater than a preset value, the controller 101 displays an overheat signal on the display unit 102 . Since the reaction by the ultraviolet ray and the photocatalyst irradiated from the ultraviolet irradiator 400 is significantly lowered when it is about 80° C. or higher, in this case, the controller displays an overheat signal and controls the operation of the fan 600 and the ultraviolet ray irradiator 400 stop

Accordingly, it is possible to prevent the ultraviolet irradiation unit 400 from being overheated or from deterioration of the photocatalytic reaction due to the inflow of high-temperature air.

Next, with reference to FIG. 4, a deodorization device according to another embodiment of the present invention will be described.

In addition, when the difference between the odor concentration detected by the intermediate sensor 803 and the odor concentration of the air detected by the outflow sensor 802 is less than a preset value, the controller 101 controls the driving unit 530 of the second deodorization filter 500 . ) to rotate the filter module 520 by 180 degrees.
