The present invention relates to an ozone and anion air sterilization deodorizing purifier, and more specifically, ozone and anion air sterilization which can remove pollutants by identifying indoor pollutants and automatically controlling the concentration of ozone or anions according to the identification result. It relates to a deodorizing purifier.

Along with the rapid industrialization, environmental pollution such as air pollution and water pollution is intensifying. In particular, there is a growing interest in indoor air pollution where people spend most of their time, and air purifiers using ozone, anion generators, photocatalyst filter decontamination machines, and electrostatic precipitators have been increasing. Various clean devices and methods are newly proposed.

Among them, ozone has a strong oxidizing power, and has various effects such as fungi, fungi, bacteria and virus sterilization, and deodorizing effects of removing various pollutants through strong chemical reactions with gaseous components. At the same time, the research and development is actively progressed in various fields for the purpose of removing harmful pollutants.

Negative ions also refer to the atomic elements of negatively-charged air that make people feel refreshed in forests, waterfalls, and hot springs.These negative ions promote cellular metabolism and enhance vitality, It is reported to have the effect of recovering fatigue and increasing appetite. Based on the pleasant natural state, the distribution of anions in the forests, hot springs, waterfalls and coastal areas is estimated to be 800 to 2,000 (cc / cc).

Conventionally, the ozone generating device and the anion device have been developed and manufactured as separate equipment, and a method in which each device controls the generation concentration of ozone and anion through predetermined control means has been mainly used.

Therefore, the user has to purchase two pieces of equipment separately for indoor air cleaning, which makes the economic burden unreasonable.

Moreover, also in the control of ozone and anion generation concentration, conventionally, the selection of a step by a control button, for example, switching operation control, current amplification control, resistance variable control, etc. by selection of strong, medium, and weak, is used. The adjustment of minute generation concentration is not considered at all.

Furthermore, by displaying the indoor air pollution indication only by using a dust sensor and a gas sensor, it is well known that there are problems such as inaccurate contamination indication due to shaking of the sensor initial value and recognition of incorrect contamination value due to an error of the sensor itself. Is true.

Therefore, it is possible to simultaneously control the ozone and anion, the emergence of a new air sterilization deodorizing purifier that can control the fine concentration of ozone and anion is urgently required.

The present invention has been made in order to accommodate the above requirements, and provides an ozone and anion air sterilization deodorization purifier that can generate an appropriate amount of ozone and anion through accurate identification detection and gas concentration measurement of the pollutant in the target space. For the purpose of

Further, another object of the present invention is to provide an ozone and anion air sterilization deodorizing purifier that can automatically adjust the discharge gap of the discharge generating means so that ozone or anion is generated according to the contamination state of the target space.

It is another object of the present invention to provide ozone and anion air sterilization deodorizing purifier that can control ozone generation so that it is harmless to human body when ozone generation and anion generation are performed in one device, and the human body is detected in the target space. It is done.

1 is a block diagram showing in detail the ozone and anion air sterilization deodorizing purifier according to a preferred embodiment of the present invention.

The ozone and anion air sterilization deodorizing purifier 100 according to the present invention includes a sensing means 110 for detecting a contamination state associated with a gas floating in a target space and generating pollution state information, and an applied voltage variable circuit unit 122. In addition, the control unit 120 receives the first applied voltage from the power supply device 150 and determines the second applied voltage by varying the first applied voltage based on the contamination state information. High voltage pulse wave generation means 130 for generating a high voltage pulse wave, and discharge discharge means 140 for generating a discharge using the high voltage pulse wave, and emitting ozone or anion generated by the discharge to the outside. It is done by

First, the sensing means 110 is an apparatus for performing identification detection processing and gas concentration measurement for a gas floating in a target space, and generates pollution state information generated by the identification detection process and gas concentration measurement. Here, the contamination state information may include gas identification information of an air pollutant, for example, reactive radicals, which are sensitive to the sensing means 100, and gas concentration information of the measured reactive active species. The reactive active species may be a kind of air pollutant identified in the sensing means 110. At this time, the sensing means 110 outputs a predetermined electric signal according to the gas concentration of the air pollution source.

The air pollutant detected by the sensing means 110 may be largely classified into a reducing gas component and an oxidizing gas component. Accordingly, the sensing means 110 of the present invention uses the reducing gas sensor 112 or the oxidizing gas sensor 114. In addition, accurate identification and detection of each gas component and gas concentration measurement are possible.

As the reducing gas sensor 112, a semiconductor type reducing gas sensor 112 which performs identification of a reducing gas component by contact with a reducing gas component and a gas concentration measuring operation due to a change in electrical conductivity may be mainly used.

The semiconductor type reducing gas sensor 112 uses the principle that the electrical conductivity of the junction portion (for example, P / N region boundary) of the semiconductor particles changes according to the kind of gas in contact. For example, when the semiconductor reducing gas sensor 112 is exposed to clean air, oxygen in the air is adsorbed on the surface of the semiconductor particles to make the electrical resistance of the surface of the semiconductor particles higher than the internal battery resistance. In particular, the junction of the semiconductor particles forms a high potential barrier (high resistance), thereby lowering the electrical conductivity.

On the other hand, when the reducing gas component is in contact with the semiconductor type reducing gas sensor 112, oxygen adsorbed on the surface of the semiconductor particles combines with the reducing gas component, thereby reducing the electrical resistance of the semiconductor particle surface and the junction (lower potential barrier). As a result, the electrical conductivity becomes high. The change in electrical conductivity varies depending on the type of gas and the concentration of the gas to be contacted. Therefore, the semiconductor type reducing gas sensor 112 can check the type of the reducing gas component to be contacted, and measure the changed electrical conductivity to determine the gas of the reducing gas component. The concentration can be measured.

In addition, the oxidizing gas sensor 114 may be used an electrically resistive oxidizing gas sensor 114 that detects the change in electrical resistance due to the chemical change caused by the oxidizing gas component adsorbed on the semiconductor surface. As is known, the electrically resistive oxidizing gas sensor 114 is a kind of semiconductor gas sensor, and the oxidation / reduction effect opposite to the reducing gas sensor 112 described above occurs. The oxidizing gas sensor 114 is a material of the semiconductor particles, such as SnO ₂ , ZnO, which are difficult to reduce, and when contacted with an oxidizing gas component, the semiconductor particles lose electrons and change electrical resistance due to chemical change. do. The change in the electrical resistance may vary depending on the oxidizing gas component and the gas concentration. Therefore, the electric resistance oxidizing gas sensor 114 enables identification detection of the oxidizing gas component and measurement of the gas concentration.

The operation control means 120 is a device for determining a pollution source removal processing method according to the air pollution source identified by the detection means 110, and determines the second applied voltage based on the determined pollution source removal process. That is, the operation control means 120 controls to generate ozone or a small amount of negative ions at an appropriate value when the air pollutant is a reducing gas component such as carbon monoxide, ethane, or ammonia, while the air pollutant is carbon dioxide, dinitrogen monoxide, or nitrogen monoxide. In the case of an oxidizing gas component such as ozone, ozone is not generated, and it is controlled to be removed by a catalytic filter having a function of removing a large amount of anions and oxidizing gas by the strong circulation mode.

Here, the second applied voltage refers to an applied voltage to the high voltage pulse wave generating means 130 to properly control the generation of ozone or anion according to the type of the air pollutant and the concentration of the air pollutant, and the voltage applied from the commercial power source. (Eg AC110 / 220, DC110 / 24V) can be varied. Therefore, the operation control means 120 varies the first applied voltage applied from the power supply device 150 to the second applied voltage so that proper ozone or anion is generated according to the removal method according to the air pollution source.

In determining the second applied voltage, the operation control means 120 of the present invention is based on the memory unit 124 for storing the pollution state information, preferably the optimum applied voltage information corresponding to the air pollution source, and the optimum applied voltage information The variable voltage circuit 122 may be configured to vary the first applied voltage. The variable processing of the first applied voltage will be described in more detail with reference to FIG. 2.

2 is a block diagram showing a configuration of an applied voltage variable circuit unit according to the present invention.

As shown in FIG. 2, the applied voltage variable circuit unit 200 includes a D / A converter 210 for converting a digital signal into an analog signal, an OP-Amp 220 for voltage amplifying the converted analog signal, and a high voltage. It may include a transistor 230 for voltage amplifying the voltage-amplified output to drive the pulse wave generating means 130.

In the present exemplary embodiment, the optimal applied voltage information stored in the memory unit 124 may include information about a discrete signal, which is a digital signal, and the discrete signal may be specified according to the type of the air pollutant identified by the sensing means 110. It can consist of binary sequences of.

In the applied voltage variable circuit unit 200 of the present invention, the first applied voltage uses a D / A converter, and sends a signal from a CPU (microcomputer) to change the voltage. That is, the source of air pollution is identified by the reducing gas sensor 114 and the oxidizing gas sensor 112, and the operation control means 120 generates an 8-bit discrete signal according to the optimal applied voltage information stored in the memory unit 124. Is generated and input to the D / A converter 210.

The D / A converter 210 receives the 8-bit discrete signal described above and the first applied voltage DC 15V from the power supply unit 150 and outputs the voltage of the analog signal. The output voltage is OP-Amp ( Voltage is amplified at 220). In addition, the D / A converter 210 may vary the first applied voltage to, for example, an output voltage of 256 grades according to an 8-bit discrete signal, so that an optimal second applied voltage is determined according to various air pollution sources. You can do that. The transistor 230 is a current amplifying apparatus for obtaining a current capable of driving the high voltage pulse wave generating means 130 at a later stage, and performs current amplification on the output voltage amplified by the OP-Amp 220. For example, when the air pollutant is identified as ammonia by the sensing means 110 and the ammonia concentration is detected to be above a predetermined reference concentration, the operation control means 120 applies the first applied voltage so that the second applied voltage becomes a specific voltage. Will be variable. That is, when the detection sensor 110 detects ammonia, the operation control means 120 inputs a discrete signal corresponding to the ammonia to the D / A converter 210. Accordingly, an output voltage is obtained at the output terminal of the D / A converter 210, and the second applied voltage is determined through voltage amplification at the OP-Amp 220 and current amplification of the transistor 230.

Accordingly, the applied voltage variable circuit unit 200 may determine the second applied voltage for generating ozone or anion appropriately based on the optimal applied voltage information of the memory unit 124.

In addition, the ozone and anion air sterilization deodorization purifier 100 of the present invention can selectively perform the generation of ozone or anion by the determination of the operation control means 120 according to the user's selection or the pollution state information. To this end, the operation control means 120 may further include a mode control unit 128 to allow the discharge discharging means 140 to be operated in one of an operation mode of ozone generation mode or anion generation mode.

The mode control unit 128 serves as a kind of selection switch, and the operation control unit 120 controls the applied voltage variable circuit unit 122 to determine the second applied voltage according to the selected operation mode. For example, in the case where the air pollutant in the target space is ammonia as described above, in the ozone generating mode, the output voltage of the discharge-releasing means 140 should be maintained at 4 kV or more, so that the high-voltage pulse wave generating means 130 The second applied voltage supplied is determined to be 12V.

On the other hand, in the negative ion generating mode, the output voltage of the discharge emitting means 140 is 2.5 kV, and the second applied voltage supplied to the high voltage pulse wave generating means 130 is controlled to be determined to be 7.5V. That is, when the ozone and ion air sterilization deodorizer 100 of the present invention generates an anion as an anion generation mode, a second applied voltage is determined according to the identification information of the air pollutant, and when ozone is generated as the ozone generation mode. Next, the second applied voltage is determined according to the identification information of the air pollutant and the gas concentration information.

3 is a block diagram showing a circuit configuration of a high voltage pulse wave generating means according to the present invention.

As shown in FIG. 3, the high voltage pulse wave generator 300 includes a pulse generator 310 for generating a pulse wave using a second applied voltage, and a high voltage transformer 320 for converting a pulse wave into a high voltage pulse wave. And an electric field converter 330 for forming an unidirectional electric field from the high voltage pulse wave.

The pulse generator 310 generates a signal in the form of a pulse wave by using the second applied voltage, and converts the generated pulse wave into a high voltage pulse wave in the high voltage transformer 320 formed of an automatic transformer (not shown). The electric field converter 330 converts the high voltage pulse wave from the high voltage transformer 320 into a direct current waveform using a rectifier circuit, and applies a unidirectional electric field formed by the direct current waveform to the discharge-emitting means 140. . As such, the unidirectional electric field causes the discharge releasing means 140 to generate a discharge to generate ozone or anion, and the ozone or anion is affected by the unidirectional electric field generated by the electric field converter 330 to the target space. It is easily discharged.

The discharge emitting means 140 generates a discharge using a unidirectional electric field, and discharges ozone generated at the same time as the discharge into the target space. The charged ozone moves in a predetermined direction by electric force in the discharge releasing means 140 in which the unidirectional electric field is formed, and is discharged to the outside through one surface in the discharge releasing means 140. With reference to FIG. 4, the structure of discharge discharge means is demonstrated in detail.

4 is a block diagram showing the configuration of the discharge emitting means according to the present invention.

As shown in FIG. 4, the discharge emitting means 400 is formed in a bed network structure including a pair of opposing electrodes. That is, the discharge emitting means 400 is an electrode structure in which the needle-shaped discharge electrode 410 and the electric field-type ground electrode 420 face each other, and maintain the discharge gap for efficient field effect discharge of ozone and anion appropriately. The discharge gap may mean a size between the needle-shaped discharge electrode 410 and the electric field type ground electrode 420, and the size of the discharge gap is adjusted by the operation control means 120. The discharge gap size is adjusted to generate a discharge in which ozone or anion is generated at an appropriate level depending on the concentration of the air pollutant and the air pollutant measured by the sensing means 110. The size of the discharge gap may affect the unidirectional electric field, and the amount of ozone or anion emitted into the target space is changed by the unidirectional electric field.                     

If the discharge gap is increased under a constant applied voltage (here, referred to as a high voltage voltage applied from the high voltage pulse wave generating means 130), the amount of ozone or anion generated decreases and the discharge gap becomes excessively large. May not happen. On the other hand, as the size of the discharge gap decreases, the discharge electric field (unidirectional electric field) becomes high, which may cause the electrodes 410 and 420 to wear out due to a short or local discharge between the needle-shaped discharge electrodes 410. do. Therefore, the ozone and anion generating air sterilization deodorizing purifier 100 of the present invention properly adjusts the discharge gap in the operation control means 120 so that the discharge gap is organically adjusted according to the concentration of the air pollutant and the air pollutant in the indoor space. By controlling, it is possible to generate an appropriate amount of ozone or anion without damaging the electrodes 410 and 420. Under the discharge gap appropriately adjusted according to the air pollutant and the concentration of the air pollutant, the particles of ozone or anion are accelerated toward the electric field ground electrode 420, and the particles of the accelerated ozone or anion are accelerated by the accelerated energy. Is discharged to the target space.

In addition, the operation control means 120 of the present invention may further include a display device controller 126 for providing a user with a contamination state of the target space. The display device controller 126 divides the pollution degree of the target space detected by the pollution state information into predetermined pollution degree classes and controls the display device to be displayed on a display (not shown). For example, the pollution degree of the target space is classified into eight grades according to the measured concentration of the air pollutant, and the user is provided with information on the pollution degree together with the gas identification information and the gas concentration information of the air pollutant. The need to operate the air sterilization deodorization cleaner 100 can be imprinted. At this time, the operation control means 120 associates the pollution state information with a predetermined pollution level, and controls the display device controller 126 so that the pollution degree is displayed on the predetermined display.

In addition, the sensing means 110 of the present invention may further include an infrared remote sensor (116) for detecting whether a person is located in the target space. As the infrared sensor 180, an infrared sensor which detects heat of a human body and checks its operation according to a temperature change may be used. When the human body is sensed in the target space, the operation control means 120 changes the first applied voltage to a third applied voltage, wherein the third applied voltage maintains the ozone concentration in the target space within a concentration range that is harmless to the human body. The voltage may mean an applied voltage to the high voltage pulse wave generator 130. If the movement of the human body is detected in the target space by the infrared sensor 116, the ozone and anion air sterilization deodorizer 100 temporarily stops ozone generation and controls the ozone concentration in the target space to be harmless to the human body. The desired ozone concentration is maintained. Therefore, the infrared sensor 116 can perform the sterilization deodorization operation that is harmless to the human body even while the person is present in the object space.

The operation flow of the ozone and anion air sterilization deodorizing purifier according to the present invention having such a configuration will be described in detail.

5 is a flowchart illustrating the operation of the ozone and anion air sterilization deodorizing purifier according to the present invention in detail.

In the sterilization deodorizing and purifying method using ozone and anion of the present invention, the method may include detecting a pollution state associated with a gas floating in a target space (S510) and generating pollution state information, and applying a first application from a predetermined power supply unit 150. Receiving a voltage and varying the first applied voltage to the second applied voltage based on the contamination state information (S550), generating a high voltage pulse wave using the second applied voltage (S560), and the high voltage pearl Generating a discharge using a spa, it may include the step of emitting ozone or anions generated by the discharge to the outside (S570).

First, the air pollutant floating in the target space is identified, and the concentration of the identified air pollutant is measured (S510). This step (S510) is a process of generating the state information on the contamination state of the target space based on the gas identification information and the gas concentration information generated by the monitoring means 110. In addition, the operation control means 120 determines the pollution degree in the target space based on the pollution state information and displays it on a predetermined display to inform the user of the contamination state of the target space.

Next, according to the user's selection or the determination of the operation control means 120 for the contamination state in the target space, the operation mode of the discharge discharge means 140 is selected (S520). This step (S520) is due to the difference between the purpose of ozone generation and the purpose of removing the air pollutant and the provision of clean air, the purpose of the negative ion generation, the operation mode can operate in one of the operation mode of ozone generation mode, anion generation mode. have. That is, when the pollution of the target space is serious and the purpose of removing the air pollutant source is to generate ozone as an ozone generating mode, while the concentration is below an appropriate level, the purpose is to make the air in the target space comfortable. The negative ion can be generated as an anion generating mode. As described above, the selection of each operation mode may be selected by a manual operation of the user, and the operation mode may be selected according to a predetermined program based on the contamination state information by the determination of the operation control means 120.

Next, the presence or absence of a person in the target space by the infrared sensor 116 is determined (S530). The step S530 may be performed independently during the above-described series of processing steps S510 and S520. When the person is in the target space, the third applied voltage may be applied to the third applied voltage regardless of the above-described pollution state information. Variable to the applied voltage (S540). Here, the third applied voltage may mean an applied voltage to the high voltage pulse wave generator 130 within a concentration range in which the ozone concentration of the target space is harmless to the human body. That is, when a person is present in the target space, it operates in the mode of removing ozone, and the operation function and the applied voltage conditions are varied and controlled in the mode of generating a large amount of negative ions.

If there is no person in the target space in step S540, the second applied voltage is determined by varying the first applied voltage supplied from the power supply device 150 based on the generated pollution state information (S550). This step (S550) determines the optimum voltage applied to the high voltage pulse wave generating means 130 according to the concentration of the air pollutant and the air pollutant, the second applied voltage is the above-described pollution state information, the memory unit 124 May be determined based on the optimal applied voltage information, the operation mode selection information, the optimal discharge gap size information, and the like.

The high voltage pulse wave generating means 140 generates a high voltage pulse wave using the second applied voltage or the third applied voltage (S560). This step (S560) is a process of generating a high voltage pulse wave having the electric field effect for the discharge generation of the discharge emitting means 140 for ozone or negative ion generation and the external discharge of ozone or anion.

Next, by using the generated high voltage pulse wave, the ozone or anion generated by the discharge emitting means 140 is released into the target space (S570). This step (S570) is a process of removing the air pollution source by adjusting the amount of ozone or anion generated according to the pollution state information. The removal method is different depending on the components of the air pollutant. For example, the reducing gas component in the target space can be removed by combining with ozone or anion, and the oxidizing gas component in the target space can contain a large amount of anions and a predetermined catalytic filter. It can be removed by the filtering process by. In addition, the operation control means 120 controls the discharge discharge means 140 to adjust the size of the discharge gap in accordance with the contamination state information, so that an appropriate amount of ozone or anion is released into the target space.

As described above, the ozone and anion air sterilization deodorizing purifier 100 of the present invention has an advantage of precisely identifying a pollutant in a target space and generating an appropriate amount of ozone or anion corresponding to the sterilization and deodorization.

For example, although the present invention exemplifies that the discharge-emitting means has a bed network structure and a unidirectional electric field is formed, the technical idea of the present invention, which identifies a source of pollution and controls the concentration of ozone and anions, is different from that of discharge. It is apparent to those skilled in the art to which the present invention is applicable as it is.
