The air purification module 100 of the present invention is mounted in an internal space of a small-sized vehicle-mounted air purification apparatus which is mounted on a vehicle and operates through a vehicle power source. The air purifying device has a housing structure capable of sucking air in the vehicle from one direction and discharging it in the other direction. The air purifying device has a diameter of 50 mm to 100 mm and a height of 80 mm to 100 mm, Any device may be used as long as it has a cylindrical space of 150 mm or a rectangular parallelepiped space of 50 mm to 100 mm in length and 80 mm to 150 mm in height. For example, the housing structure may include a structure in the form of a tumbler having a cylindrical interior space for receiving the air purification module 100.

1, the air purifying module 100 includes two photocatalyst panels 105, a plurality of silicon compound beads coated with a photocatalyst material and integrated in a panel form, Four UV lamp units 110 for emitting ultraviolet UV light and two UV lamp units 110 on one surface facing the photocatalyst panel 105 and fixing the UV lamp unit 110 And two photocatalytic panels 105 are formed so as to form a flow path of air between the two photocatalytic panels 105, The two UV lamp units 110 disposed in the two lamp arranging units are directed toward the designated photocatalyst panel 105 and arranged in a geometric relationship spaced apart from each other by a specified vertical distance A frame part 125 for fixing, And a power supply unit 145 for generating an operation power for applying a constant current of 350 mA (+/- 10 mA) per UV lamp unit 110 using a vehicle power source applied from the power supply unit 145.

The photocatalyst material is a general term for a material that accepts light and promotes a chemical reaction. Preferably, the photocatalyst material of the present invention includes titanium oxide (TiO 2). According to the present invention, the titanium oxide is characterized in that it absorbs UV and promotes the chemical reaction of almost all substances except silicon.

The photocatalyst panel 105 of the present invention is manufactured by integrating a plurality of silicon component beads coated with a photocatalyst material in a panel form and having a specified geometrical structure. According to the method of the present invention, the photocatalytic panel 105 is formed by integrating a plurality of silicon component beads having a diameter r (0.4 mm? R? 1.5 mm) coated with a photocatalyst material in a panel form, t < / = 12 mm) is molded into a panel shape or a plurality of silicon component beads coated with the photocatalyst material are integrated and molded in a panel shape having a specified thickness t (4 mm? t? 12 mm) In the form of a panel.

According to the method of the present invention, the geometry of the photocatalytic panel 105 includes a rectangular structure having a short side length x (40 mm? X? 80 mm) and a long side length y (80 mm? Y? 120 mm) can do. However, the geometric structure of the photocatalytic panel 105 is not limited to a rectangular structure. Depending on the structure of the air purifying device having the air purifying module 100 having the photocatalyst panel 105, various types of geometric structures (E.g., a polygonal structure such as a pentagonal or hexagonal shape, a circular or elliptical structure, etc.).

The photocatalyst panel 105 of the present invention is manufactured by integrally molding a plurality of silicon component beads coated with the photocatalyst material, for the following reasons. First, the silicon component is safe for the photocatalytic material (TiO2). Secondly, since the silicon component (= glass) efficiently transmits UV, the UV emitted from one direction of the photocatalyst panel 105 is transmitted to the beads accumulated in the opposite side of the photocatalyst panel 105, The photocatalytic function of the photocatalyst material coated on the photocatalyst can be activated. Third, when spherical beads are integrated, the contact area between each bead and beads is minimized, and the contact area where the air contact with the photocatalyst material coated on each bead can be maximized. Meanwhile, when the diameters of the beads used for manufacturing the photocatalytic panel 105 of the present invention are made equal, the air gap between each bead and the bead is maximized, and the transmittance of air permeating the panel increases. On the other hand, The contact area where the photocatalyst material 105 and the photocatalyst material 105 are in contact with each other is maximized, instead of reducing the air gap and the transmittance between the beads and the beads.

According to the method of the present invention, the photocatalytic panel 105 can be manufactured by mixing and mixing beads of a part of equal diameter and part of unequal diameter. In this case, the air flowing along each side of the photocatalytic panel 105 is permeated into the inside of the photocatalytic panel 105 through the air formed by the beads of the photocatalytic panel 105, The reaction time (or the contact holding time) in which the air and the photocatalyst material are in contact with each other may be maximized as the contact area for contacting the photocatalyst material coated on the substrate is increased. As the contact area between the air and the photocatalyst material is increased and the reaction time (or contact holding time) during which the air and the photocatalyst material are in contact with each other increases, harmful components of the air become more completely harmless (or safe) ≪ / RTI >

The UV lamp unit 110 is a general term for a component that emits UV of a UV-A wavelength band (for example, 320 to 405 nm wavelength band) at a designated light intensity. For example, the UV lamp unit 110 may include a UV lamp unit 110, a UV lamp unit 110, a UV lamp unit 110, The photocatalyst material coated on the beads integrated in the inside of the photocatalytic panel 105 or on the opposite side of the panel to be irradiated with the UV light of the UV lamp unit 110 It is possible to emit UV in the UV-A wavelength band irradiated with light intensity of 6 to 10 mW / cm 2 (± 1 mW / cm 2).

On the other hand, the UV lamp unit 110 is manufactured by setting a radiation angle on the specification that emits UV in the UV-A wavelength band. Here, the radiation angle on the spec is a radiation angle set on the specification set by the manufacturer designing or manufacturing the UV lamp unit 110. For example, the UV lamp unit 110 may be manufactured to include a radiation angle on a specimen including any one of the angular ranges of 120 DEG to 160 DEG. However, the radiation angle on this specification means only the maximum angle range in which UV can be emitted from the UV lamp unit 110, and the UV emitted from the UV lamp unit 110 has effective light intensity and effective wavelength spectrum But does not mean an angle range that can be reached. Accordingly, the present invention can be applied to a case in which the UV emitted from the UV lamp unit 110 has an effective light intensity (for example, light intensity for activating the photocatalytic function of the photocatalyst material) and an effective wavelength spectrum And a wavelength spectrum including a wavelength value for activating the photocatalytic function of the photocatalyst material in a peak wavelength region) is preferably set and used. For example, the radiation angle in the design may be a distance between the photocatalyst panel 105 and the UV lamp unit 110 (for example, a vertical distance between one side of the photocatalyst panel 105 and the UV lamp unit 110) (For example, the length of the long side or short side of the rectangular structure, the diameter or radius of the circular or elliptical structure, etc.) of the surface of the photocatalytic panel 105 and the characteristics of the operating power applied to the UV lamp unit 110 (Or a combination of two or more) of the current-voltage characteristics (e.g., constant-current state, etc.).

According to the first exemplary embodiment of the present invention, the radiation angle? In the design may include a radiation angle range on the specification of the UV lamp unit 110 as it is. For example, if the UV emitted from the UV lamp unit 110 is effective in the light intensity and effective wavelength spectrum of each panel region of the photocatalytic panel 105 within the radiation angle range of the specification of the UV lamp unit 110 If possible, the design angle of theta [theta] may comprise a range of the radiation angle on the spec. For example, when the radiation angle on the specification of the UV lamp unit 110 is 120 °, the radiation angle θ in the design may include 120 °.

According to the second embodiment of the present invention, the radiation angle θ in the design may include a range in which the radiation angle range on the specification of the UV lamp unit 110 is reduced by a certain ratio. For example, based on the distance between the UV lamp unit 110 and the photocatalyst panel 105 and the characteristics of the operation power source applied to the UV lamp unit 110, When the effective light intensity and the UV of the effective wavelength spectrum can reach each panel region of the photocatalytic panel 105 in the range of 2/3, the radiation angle θ in the design corresponds to 2/3 of the radiation angle range on the specification And the like. For example, when the radiation angle on the specification of the UV lamp unit 110 is 120 °, the radiation angle θ in the design may include 90 ° corresponding to 2/3 of 120 °.

According to the third exemplary embodiment of the present invention, the design angle of the radiation &thetas; may be set to a shape including at least a part of the angular range of the angular ranges of the first and second embodiments. For example, the radiation angle &thetas; in the design may be set to a shape including at least a part of the angular range of the radiation angle range on the spec in a range in which the radiation angle range on the specification is reduced by a certain ratio. For example, the design angle of deflection &thetas; may comprise an angular range of at least some of the angles from 90 DEG to 160 DEG.

According to an embodiment of the present invention, a lamp arrangement having two UV lamp units 110 and a lamp-related circuit configuration and having a heat dissipation fin unit 120 for radiating heat of the UV lamp unit 110, The lamp arrangement frame part 125 forms a flow path for air flow between the UV lamp part 110 and the photocatalytic panel 105 disposed in the lamp arrangement part 115, The UV emitted from the UV lamp unit 110 is irradiated onto the photocatalyst material coated on the beads integrated in the photocatalyst panel 105 with an effective light intensity and an effective wavelength spectrum maximizing the photocatalytic function of the photocatalyst material, The photocatalytic panel 105 and the lamp arrangement part 115 can be arranged and fixed.

According to the embodiment of the present invention, the lamp arrangement frame part 125 is disposed in the lamp arrangement part 115 so as to form a flow path for flowing air sucked from inside the vehicle to the vicinity of the air discharge fin part provided in the lamp arrangement part 115 115 are preferably arranged and fixed.

Referring to FIG. 1, the air purifying module 100 sucks air in the vehicle and flows through a specified flow distance while sequentially contacting the respective surfaces of two photocatalyst panels 105 arranged in a zigzag structure, (S > = 0.5) second or more before the fan unit 140 is started, and a fan unit 140 generating a pressure that requires a flow time of at least s And a discharge unit 135 having a designated discharge area for discharging the air sucked from the inside of the vehicle based on the pressure by the fan unit 140.

The suction part 130 is provided in at least one frame part 125 of the upper frame part 125 and the lower frame part 125. The discharge part 135 is also provided in the upper frame part 125 and the lower frame part 125. [ May be provided in at least one of the frame parts 125 of the frame part 125. For example, when the suction part 130 is provided on one side of the lower frame part 125 with reference to the arrangement position of the photocatalytic panel 105, the discharge part 135 may be provided on the side of the photocatalytic panel 105 And may be provided on the other side of the upper frame part 125 on the basis of the placement position.

According to the method of the present invention, the discharge area of the discharge part 135 is set to be less than or equal to the suction area to maximize the flow time of the air sucked from the inside of the vehicle while contacting the photocatalyst panel 105 (Or the suction area of the suction unit 130 includes an area that is smaller than or equal to the discharge area to maximize the flow time during which air sucked from the inside of the vehicle flows in contact with the photocatalyst panel 105) . However, the relationship between the area of the discharge area and the area of the suction area is not limited to the above-described relationship. When the flow time can be controlled by the pressure formed by the pan part 140, the area relationship between the discharge area and the suction area may be omitted Do.

The power supply unit 145 includes a power supply unit (not shown) supplied with vehicle power from the vehicle, and an operation power source for UV light emission of the four UV lamp units 110, And a power application unit (not shown) for applying the generated operation power to the UV lamp unit 110 and the pan unit 140. The method of implementation And a power charging unit (not shown) that charges the vehicle power supplied through the power supply unit or the operation power generated through the power conversion unit.

Meanwhile, according to the experiment of the applicant, in order to keep the wavelength spectrum of the UV lamp unit 110 constant or to reduce the deformation of the wavelength spectrum due to external environment change, the voltage applied to the UV lamp unit 110 is kept constant It is preferable to apply a constant current to keep the current value constant rather than constant. The power supply unit 145 may include a full current circuit for generating a specified constant current to be applied to the four UV lamp units 110 based on the vehicle power supplied from the vehicle through the power supply unit. Conventional UV emission related circuits are designed to maintain a constant voltage rather than a constant current. The present invention is characterized in that a constant current is maintained.

According to an embodiment of the present invention, the power source unit 145 generates an operation power source for applying a constant current of 350 mA (± 10 mA) to each UV lamp unit 110 through a vehicle power source or a charged power source applied from a vehicle And the operating power source may include a variable DC voltage of 3.5V (+/- 1.0V) for each UV lamp unit 110 to maintain the constant current. The power supply unit 145 applies a constant current of 350 mA (± 10 mA) and a variable voltage of DC 3.5 V (± 1.0 V) to each of the two UV lamp units 110. Meanwhile, when the constant current value of 350 mA (± 10 mA) is applied to each UV lamp unit 110, the power source unit 145 checks whether the constant current value is changed over the allowable range. If the constant current value is changed over the allowable range It is preferable to maintain the constant current value as much as possible even if the voltage value is varied.

According to the embodiment of the present invention, it is preferable that the power supply unit 145 apply operating power based on the vehicle power applied from the vehicle to the circuits provided in the two lamp arrangement units 115 in parallel relation, Each of the lamp arranging units 115 preferably applies a power source applied in parallel from the power source unit 145 to each of the two UV lamp units 110 in series. For example, in a vehicle power source of most vehicles other than a bus or a heavy lorry, a DC voltage of 12V is required. For each UV lamp unit 110, a required voltage value is DC 3.5V. When a vehicle power source is connected in series, It is not possible to apply a valid power to the power supply 110. Meanwhile, when all the four UV lamp units 110 are connected in parallel, 3.5V DC may be applied to each UV lamp unit 110 through the DC 12V. However, It is difficult to maintain a constant current value of 350mA (± 10mA). In the present invention, the operation power source based on the vehicle power source is applied in parallel to the circuits provided in the two lamp arrangement units 115, and then the two UV lamp units 110 ), A stable constant current of 350 mA (± 10 mA) can be applied to each UV lamp unit 110 by using a vehicle power source of 12 V DC. In this case, theoretically, the voltage applied to the four UV lamp units 110 is 7V and 9V (= (3.5V + 1.0V) * 2) even when the maximum voltage allowable value per each UV lamp unit 110 is taken into consideration. The remaining power source of 3V is generated at the 12V of Kyungwoon, and the power source unit 145 may be used as an operating power source for operating the fan unit 140 using the reserved power source, or may be used as a control module for the air purifying module 100 It can be used as an operation power source of the control module.

The fan unit 140 is provided on at least one side of the suction unit 130 and the discharge unit 135 to suck air from the inside of the vehicle through the suction unit 130, A flow path between the photocatalytic panel 105 and the UV lamp unit 110 or between the photocatalytic panel 105 and the photocatalytic panel 105 flows and then generates a pressure for discharging the discharge unit 135. Preferably, the fan unit 140 includes a propeller and a motor for generating the pressure, and a body for fixing the propeller and the motor. The motor is rotated at a predetermined rotation speed To rotate the propeller. Meanwhile, the power supply unit 145 (or a separate control module) may have a control circuit or a control-related configuration for controlling the rotation speed of the motor when the motor rotation speed of the fan unit 140 is varied and controlled , Whereby the present invention is not limited thereto.

According to the method of the present invention, the photocatalytic panel 105 is formed so as to have a flow distance f (40 mm < = f < = 120) at which air flowing in contact with one surface of the photocatalytic panel 105, Mm) can be set. For example, a rectangular photocatalytic panel 105 having a short side length of 60 mm and a long side length of 80 mm is disposed vertically in a vertical direction as shown in FIG. 1, and a suction part 130 of the lower frame part 125 is disposed, The flow distance f of the photocatalyst panel 105 may be 80 mm when the air sucked from the photocatalyst panel 105 flows in contact with one surface of the photocatalyst panel 105.

On the other hand, when the two photocatalyst panels 105 having the flow distance f are arranged in a zigzag manner as in the embodiment of FIG. 1, the air sucked from the suction portion 130 side of the lower frame portion 125 passes through the two photocatalytic panels (F? 3 * f), in which the fan unit 140 is configured to allow the air sucked through the suction unit 130 to flow through the designated It is preferable to generate a pressure that takes at least the specified flow time s (s? 0.5 seconds) until the fluid flows through the flow path F and is discharged to the outside through the discharge portion 135.

According to the embodiment of the present invention, the fan unit 140 takes a flow time of 1 second or more for the air sucked from inside the vehicle in the designated operation mode (for example, the normal mode or the low noise mode) Even if the motor of the fan unit 140 rotates at a high speed, the air sucked from the inside of the vehicle seeps into the beads of the photocatalyst panel 105 and reacts with the photocatalyst material It is preferable to secure a flow time (for example, reaction time) of at least 0.5 seconds or more so as to ensure a minimum reaction time (or contact holding time) for decomposing harmful substances. That is, in order to maintain the probability that the photocatalyst material of the photocatalyst panel 105 decomposes harmful components in the air in the air purifying module 100 of the present invention at a certain level or more, the minimum reaction time (Or contact holding time) is maintained, and since the propeller of the pan section 140 is rotated at a high speed to rapidly flow the air, more air is not decomposed more quickly or cleaned more quickly. According to the experiment of the applicant, a flow time of at least 0.5 seconds must be ensured until the air sucked through the suction unit 130 flows through the specified flow path distance F and is discharged to the outside through the discharge unit 135 , Preferably a flow time of 1 second or more should be secured.

Meanwhile, according to the method of the present invention, when the air sucked through the suction unit 130 flows through the predetermined flow path distance F and is discharged to the outside through the discharge unit 135, At least at a specified rotational speed v to produce a pressure that takes at least the specified flow time. The rotation speed of the propeller provided in the fan unit 140 may be controlled by a voltage value or a current value of the operation power supplied to the motor of the fan unit 140 or may be controlled by a control circuit for controlling the rotation speed of the motor, Can be controlled by a signal delivered from the configuration.

According to the method of the present invention, the designated rotational speed v of the propeller provided in the pan portion 140 for securing the flow time is determined by the flow rate When the discharge area of the discharge part 135 is smaller than or equal to the suction area of the suction part 130, the suction area of the suction part 130 may be calculated using parameters such as the discharge area and the suction area of the suction part 130, The designated rotational speed v of the propeller provided in the pan portion 140 can be calculated using a parameter such as the flow path distance F and the discharge area of the discharge portion 135 as factors. Accordingly, the air sucked through the suction unit 130 flows through the predetermined flow path distance F and is discharged to the outside through the discharge unit 135 based on the flow path distance F and the discharge area of the discharge unit 135 , The power supply unit 145 (or another control module) supplies power to the pan unit 140 to maintain the calculated rotation speed v, Or a signal for maintaining the calculated rotational speed v.

The suction unit 130 sucks air inside the vehicle from a specified direction based on the pressure generated by the rotational speed v of the propeller of the fan unit 140, It is preferable that the air sucked from the inside of the vehicle is discharged in the other direction.
