The cleaning method is a method of treating odorous substances by washing them with water, chemicals, etc., and the operating cost is low, but the scope of application is narrow, and there is a disadvantage that it must be accompanied by treatment of contaminated wastewater generated after cleaning.

The adsorption method utilizes the adsorption power of a porous material such as activated carbon, and has a wide range of applications and an advantage of being easy to install, but there is a trouble of periodically replacing the activated carbon when the life of the activated carbon is over.

The microbial treatment method uses microorganisms to decompose odorous substances, and has the advantage of not generating secondary pollutants, but it is inconvenient to continuously maintain the growth conditions required by microorganisms.

Oxidation method is a method of removing odors by using the strong oxidizing power of ozone, and it is easy to maintain and manages, and it is possible to treat a large capacity, and thus has been in the spotlight recently.

It provides an odor removal device that guides the filter replacement timing.

In an embodiment, the control unit may stop the operation of the radical generator when a radical flow is measured by the first radical sensor.

In addition, in an embodiment, the control unit may control the radical generator so that the intensity of generation of radicals gradually decreases at every preset time interval after the radical generator starts to operate.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Referring to Figure 1, looks at the odor removal device according to an embodiment of the present invention. 1 is a schematic diagram showing the configuration of an odor removal apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the odor removal apparatus 100 according to an embodiment of the present invention includes a housing 110, a radical generator 130, a first radical sensor 140, a radical removal filter 160, and 2 It may include a radical sensor 150, an odor removal filter 190, a blowing fan 120, a control unit 170, and a power supply unit 180.

The housing 110 includes a radical generator 130, a first radical sensor 140, a radical removal filter 160, a second radical sensor 150, an odor removal filter 190, and a blowing fan 120 to be described later. It can have an internal space that can be embedded.

Here, the internal space of the housing 110 may constitute an air flow path through which air can flow.

In one embodiment, the housing 110 may include an air inlet 112 through which external air can be introduced into the internal space, and an air outlet 114 through which air in the internal space can be discharged back to the outside. have.

In addition, the radical generator 130 is provided inside the housing 110 and may generate radicals.

Here, radicals refer to ions having a high energy level, such as ozone, oxygen, OH radicals, and hydrogen ions. When radicals react with oxidizing substances, they oxidize and disappear or are reduced to oxygen.

Through this reaction, radicals can remove oxides from the air, that is, odors and bacteria.

The radicals generated by the radical generator 130 may remove oxides from the air introduced into the housing 110.

In one embodiment, the radical generator 130 may be configured as an ionizer that is connected to a power supply unit 180 to be described later as shown in FIG. 1 to generate ions when a high voltage is applied, but is not limited thereto. .

In addition, in an embodiment, the radical generator 130 may be configured to adjust the amount of radicals generated according to the magnitude of the applied voltage.

In addition, the radical generator 130 may be provided on the air inlet 112 side of the housing 110 as shown in FIG. 1. When the radical generator 130 is provided on the side of the air inlet 112, there is an advantage that the odor flowing into the air inlet 112 can be immediately removed.

Meanwhile, the first radical sensor 140 is provided at a rear end of the radical generator 130 and may measure the concentration of radicals.

The first radical sensor 140 may measure the concentration of residual radicals remaining after reacting with the oxides in air among radicals generated by the radical generator 130.

That is, when the amount of radicals generated is greater than the amount of oxides in the air, radicals that have not reacted with the oxides remain, and the first radical sensor 140 has the radicals generated excessively compared to the oxides. Can be detected.

In addition, the radical removal filter 160 is provided at a rear end of the first radical sensor 140, and reacts with an oxide material in the air to remove residual radicals.

In one embodiment, the radical removal filter 160 may be configured as a carbon filter capable of removing radicals through a chemical adsorption reaction, but is not limited thereto.

In addition, the second radical sensor 150 is provided at a rear end of the radical removal filter 160 and may detect radicals remaining after passing through the radical removal filter 160.

The second radical sensor 150 may detect that the radical removal filter 160 is unable to remove residual radicals due to deterioration in performance as will be described later. That is, the second radical sensor 150 may perform a function of detecting the replacement timing of the radical removal filter 160.

In addition, the odor removal filter 190 is provided at the rear end of the radical generator 130, and is removed by the radicals generated in the radical generator 130 and can completely remove residual oxides, that is, residual odors.

The odor removal filter 190 has a high concentration of oxides contained in the indoor air, so when the amount of oxides is greater than the amount of radicals generated even when the radical generator 130 is operated at maximum output, for example, In an environment with a high concentration, the odor removal apparatus 100 according to an exemplary embodiment of the present invention may perform a function of auxiliaryly removing odors remaining without being removed by radicals at the initial stage of operation.

In one embodiment, the odor removal filter 190 may be formed of a carbon filter, but is not limited thereto.

In addition, the blowing fan 120 is provided inside the housing 110, and external air is introduced into the housing 110 through the air inlet 112 and then discharged back to the outside through the air outlet 114. Air can flow as much as possible.

Meanwhile, the controller 170 may control an operation of generating radicals of the radical generator 130 based on the measured value of the first radical sensor 140.

In one embodiment, the control unit 170 may control the radical generator 130 by controlling the power supply 180 supplying a voltage to the radical generator 130 to adjust the magnitude of the voltage supplied to the radical generator 130. have.

Hereinafter, the operation of controlling the radical generator 130 of the controller 170 will be described.

In an embodiment of the present invention, the control unit 170 may stop the operation of the radical generator 130 when the radical flow is measured by the first radical sensor 140.

When the radical flow is measured by the first radical sensor 140, it means that the amount of the radical flow generated by the radical generator 130 is greater than the amount of oxide in the air. That is, in this case, it means that the entire amount of odor has been removed by radicals.

Accordingly, the control unit 170 may cut off the power supply to the radical generator 130 so that the radical generator 130 no longer generates radicals when all of the odors are removed as described above.

In addition, in an embodiment, the control unit 170 may control the radical generator 130 so that the intensity of generation of radicals gradually decreases at every preset time interval after the radical generator 130 starts to operate.

For example, the control unit 170 operates the radical generator 130 at 100% at the beginning of the operation of the odor removal apparatus 100 according to an embodiment of the present invention, and operates at 50% when a preset time elapses. If the preset time elapses after that, it can be operated with less than 10%.

That is, when the odor removal device 100 according to an embodiment of the present invention is operated, the concentration of the oxide substance in the room gradually decreases, and in response to this, the control unit 170 controls the radical flow generation intensity of the radical generator 130. Can be gradually lowered over time.

However, the present invention is not limited thereto, and the control unit 170 may operate the radical generator 130 with a constant output until a radical flow is detected by the first radical sensor 140.

Meanwhile, the control unit 170 is connected to the second radical sensor 150 and may perform an alarm function when the radical removal filter 160 is exchanged when a radical flow is detected by the second radical sensor 150. .

Here, the filter replacement time alarm of the control unit 170 may be displayed through a warning screen, a warning light, a warning speaker, etc. provided in the device, or may be displayed through a separate display device (not shown).

The odor removal apparatus 100 according to an embodiment of the present invention removes odor and detects residual radicals, and controls the radical generator 130 according to the detected value, thereby generating the concentration, type, and occurrence of odor. There is an advantage that it can be operated optimally over time.

For reference, the odor removal apparatus 100 according to an embodiment of the present invention may be applied to various products such as a food waste treatment machine, a bidet, and an air purifier.
