Description

[Technical field]

[0001] The present disclosure relates to a catalyst device and an air conditioning device for a vehicle incorporating the same, and more particularly to a catalyst device and an air conditioning device for a vehicle incorporating the same, which can adjust the optimal distance and the optimal angle between a light source portion and a catalyst portion to purify the air flowed into an air conditioning case, stably sterilize an evaporator, and safely protect the occupant in a vehicle, and thus implement the maximum performance of sterilization and deodorization for the evaporator. [Technical background]

[0002] An air conditioning device for a vehicle as a device for cooling or heating the interior of the vehicle by heating or cooling the air in the process of flowing the outside air of the vehicle into the vehicle or circulating the air of the vehicle interior includes an evaporator for the cooling operation and a heater core for the heating operation within an air conditioning case, and uses a blowing mode changeover door for selectively blowing the air cooled or heated by the evaporator or the heater core into each section in the vehicle interior.

[0003] Japanese Patent No. 2549032 (filed on May 30, 1997, entitled “Cooling apparatus with deodorizer for vehicle”), filed earlier, disclosed a cooling apparatus with an air purifier for a vehicle.

[0004] Fig. 1 is a cross-sectional view illustrating the conventional cooling device with the air purifier for the vehicle.

[0005] In Fig. 1, the conventional cooling device with the air purifier for the vehicle is provided with an outside air intake port 21 and an inside air intake port 22 in a housing 20 and pivotally provided with an inlet door 23 that selectively opens and closes the outside air intake port 21 and the inside air intake port 22. An actuator 30 is connected to the rotation axis of the inlet door 23 and controlled by the control means 31.

[0006] The inlet door 23 is provided on its downstream side with a blower 25 for blowing the air flowing from the inside and outside air intake ports 21, 22 to its downstream side. The blower 25 consists of a fan 32 and a motor 33 that rotates the fan 32. An evaporator 26 is located on the downstream side of the blower 25 to exchange heat with the air passing through it and thus cool the air.

[0007] An air passage 28 formed on the downstream side of the evaporator 26 is provided with a catalyst filter 27 to generate active oxygen by irradiating the light having a long wavelength.

[0008] The catalyst filter 27 generates active oxygen through irradiation with an ultraviolet lamp 29. The active oxygen oxidizes and decomposes the odor-causing substance into an oxidizable compound at a very low concentration. The ultraviolet lamp 29 is arranged between the evaporator 26 and the catalyst filter 27.

[0009] A metal catalyst filter 34 for removing the ozone contained in the flowing air is provided on the downstream side of the catalyst filter 27. Reference numeral 35 denotes a temperature sensor, 36 a sensor for sensing the odor level, 37 a fan switch, and 28 an air outlet, which are not described.

[0010] However, there is a problem that in the conventional cooling device with the air purifier for the vehicle, the ultraviolet lamp 29 used as the light source of the catalyst contains mercury, which is harmful to the human body, and cannot be used for the vehicle due to various environmental regulations.

[0011] In addition, there is a problem in that the catalyst filter 27 is provided on the downstream side of the evaporator 26 to absorb and deodorize the odor generated in the evaporator 26, so the filter needs to be replaced due to a decrease in the air volume caused by an excessive amount of dust. In addition, there is a problem in that, in the conventional vehicle-type cooling device with the air purifier, the ultraviolet lamp 29 and the catalyst filter 27 are separate parts, thus reducing the assemblability.

[0012] DE 11 2015 000 098 T5 discloses a photocatalyst for use in a vehicle air conditioning system, in which light emitted by a light source part is guided to the catalyst part so that it is collected there and enhances the catalyst reaction. For this purpose, the dimensions of a space forming section in which the light source and the catalyst part are arranged are selected accordingly.

[0013] JP 2008-104 739 A discloses a photocatalyst for use in an air purifying device, in which a reflector is arranged behind the catalyst part as viewed from the position of the light source.

[0014] US 2018 / 0280559 A1 discloses a photocatalytic element in which the distance between the light source and the surface of the photocatalytic material is adjusted so that the surface assumes a desired temperature upon irradiation. [Revelation][Technical Problem]

[0038] Hereinafter, a catalyst device and an air conditioning device for a vehicle incorporating the same in accordance with the present disclosure having the above-described characteristics will be described in detail with reference to the accompanying drawings. Fig. 2 is an exploded perspective view illustrating a catalyst device in accordance with a first embodiment of the present disclosure, Fig. Figure 3 is a longitudinal cross-sectional view of the state in which Fig. 2 has been assembled, Fig. Fig. 4 is a graph illustrating the distance between the conventional light source section and the catalyst section, and Fig. 5 is a graph illustrating the distance between the light source portion and the catalyst portion in accordance with the first embodiment of the present disclosure.

[0039] In the Fig. 2 to 5, a catalyst device 100 in accordance with an embodiment of the present disclosure is configured to include a body 110, a light source portion 120 for emitting ultraviolet light, a catalyst portion 130, a housing 140, and a sealing portion 150.

[0040] The catalyst device 100 includes, for example, the housing 140, the light source portion 120 arranged to face the interior of the housing 140 to emit light toward the inner surface of the housing 140, and the catalyst portion 130 located on the inner surface of the housing 140 and generating the photocatalytic reaction by the light emitted by the light source portion 120; wherein the catalyst portion 130 is arranged a first distance L away from the light source portion 120 so that the maximum optical energy Pmax of the light source portion 120 is concentrated thereon.

[0041] In particular, according to the present embodiment, the catalyst portion 130 can concentrate the maximum optical energy Pmax of the light source portion 120 thereon and thus stably deodorize the evaporator regardless of the size reduction.

[0042] In addition, it is possible to arrange the light source portion 120 and the catalyst portion 130 at the first distance L to easily concentrate the maximum optical energy Pmax thereon, and thus prevent the reduction of the deodorization efficiency due to the size reduction.

[0043] The body 110 is mutually assembled with the casing 140 to provide the space in which the light source section 120 and the catalyst section 130, which will be described later, can be stably installed.

[0044] The body 110 has a receiving portion 111 for inserting a substrate 122, the substrate 122 being provided with the light source portion 120 for radiating ultraviolet (UV) light having a first wavelength range on its upper surface.

[0045] The housing 140 may be configured such that an upper and a lower housing are assembled together, as illustrated in the figure, or may be separately composed of the left and right housings, which are also assembled together.

[0046] The light source section 120 according to the present embodiment can selectively use any one of an ultraviolet ray having a first wavelength range or a visible ray having a second wavelength range.

[0047] Because the light source section 120 uses an LED, it is harmless to the safety of the driver in the vehicle even when the vaporizer is sterilized, and it can be easily repaired even if a malfunction occurs. Accordingly, it is possible to simultaneously improve passenger safety and the sterilization efficiency of the vaporizer.

[0048] Because the power supply socket 102 is provided on the substrate 122, it is possible to stably supply the power source when it is intended to be supplied to the light source section 120. When the body 110 and the casing 140 are assembled together at the member (not shown) provided on the substrate 122 or the light source section 120, it is possible to achieve stable operation of the light source section 120.

[0049] Because the light source section 120 uses the LED, it is possible to use it safely because it does not cause any problems to the health of the occupant along with the stable sterilization for the vaporizer.

[0050] Before describing the light source section 120, the catalyst section 130 is extended with the same horizontal and vertical lengths and is extended, for example, with the length of the horizontal 44 mm * the vertical 44 mm.

[0051] When the horizontal length of the extended length of the catalyst portion 130 is relatively shorter than the conventionally used length and the ultraviolet light is irradiated onto the catalyst portion 130, the irradiation is carried out as the state in which the light amount of the optical energy has been changed.

[0052] That is, for the ultraviolet light emitted from the light source portion 120, the location where the maximum optical energy Pmax is concentrated is changed due to the change in the distance between the light source portion 120 and the catalyst portion 130, and will be described in more detail with reference to the drawings.

[0053] Fig. Fig. 4 is a graph illustrating the distance between the light source portion and the catalyst portion in the prior art, while Fig. 5 is a graphical representation illustrating the distance between a light source portion and a catalyst portion in accordance with an embodiment of the present disclosure.

[0054] In the Fig. 4 and Fig. 5, the distance L between the light source portion 12 and the catalyst portion 13 in the prior art is relatively shorter than the first distance L between the light source portion 120 and the catalyst portion 130 in accordance with the present disclosure.

[0055] Further, the length of the conventional catalyst portion 13 is extended to be relatively longer than that of the present disclosure, for example, the conventional distance L is kept at a distance of 5 mm.

[0056] In this case, when the ultraviolet light is emitted from the light source sections 12, 120 having the same specification, the maximum light energies Pmax emitted to the catalyst sections 13, 130 become different between the prior art and the present disclosure.

[0057] The maximum optical power Pmax of the catalyst portion 13 is maintained in the state spaced at the distance corresponding to the intensity 1 / 3 * P based on 5 mm which is the vertical distance between the light source portion 12 and the catalyst portion 13 in the prior art.

[0058] In contrast, according to the present embodiment, the first distance L between the catalyst portion 130 and the light source portion 120 is spaced at the distance corresponding to the intensity 2 / 3θP that covers only the lower top surface area of ​​the catalyst portion 130 when the amount of light P is emitted from the light source portion 120, based on the vertical distance between the light source portion 120 and the catalyst portion 130.

[0059] Here, the definition of the lower region is a region where the amount of light is concentrated when the catalyst portion 130 is viewed from its side surface, and the entire region where the actual amount of light P is reached is 1 / 3 * P.

[0060] In the prior art, the maximum optical energy Pmax of the ultraviolet light emitted to the catalyst section 13 is reached at 1 / 3 * P of the light source section 12. In this case, the manufacturing cost increases due to the increase in the size of the catalyst section 13, and the deodorization effect of the evaporator is excellent, but the cost is increased.

[0061] The present embodiment reduces the size of the catalyst portion 130 and separates the first distance L between the light source portion 120 and the catalyst portion 130 at a specific distance to improve the above conventional problems.

[0062] Then, it is possible to maximize the optical energy Pmax emitted from the light source portion 120 and thus stably deodorize the evaporator without reducing the efficiency due to the size reduction of the catalyst portion 130.

[0063] In addition, although the size of the catalyst section 130 has been reduced compared to the conventional catalyst section, the optical energy of the light source section 120 can be more concentrated, thus generating no unnecessary dead zone.

[0064] The first distance L according to the present embodiment is set at 15 mm, for example, based on the light source section 120 relative to the catalyst section 130. When the vertical distance between the light source section 120 and the catalyst section 130 is set to be 2 / 3 * P corresponding to the maximum optical power Pmax of the light source section 120, the first distance L concentrates the maximum optical power Pmax of the light source section 120 at a length of 15 mm, as described above.

[0065] In this case, even if the ultraviolet light of the light source section 120 is maximally concentrated on the catalyst section 130 and its area is reduced, the efficiency of the catalyst section 130 is excellently maintained.

[0066] The first distance L according to the present embodiment is set to the length of the catalyst section * 1 / 2 * tanθ / 2. The first distance L has the correlation with the size of the housing 140 and the maximum optical power of the light source section 120, and the optimal distance can be calculated using the above equation and applied to actual products.

[0067] In the light source section 120 according to the present embodiment, the diffusion angle (θ) of the light source section 120 is maintained within a range of 20 degrees to 60 degrees based on the maximum optical power. This diffusion angle is applied when the catalyst section 130 is located within the dashed line range by the above-described first distance L, as illustrated in the figure.

[0068] In this case, the maximum optical energy can be radiated within a range of diffusion angles, and the efficiency of the catalyst section 130 can be kept at a maximum accordingly. For example, the light source section 120 radiates to the catalyst section 130 at the entire diffusion angles within a range of approximately 120 degrees.

[0069] The light source section 120 according to the present embodiment uses the LED, and thus it is possible to use it safely because no hazardous components are discharged or there is no potential danger, so that it is possible to repair and replace it easily even if a malfunction is caused, thus improving the workability of the operator.

[0070] The LED emits ultraviolet A light (UVA light) or ultraviolet C light (UVC light) with a wavelength of 400 nm or less, making it possible to solve the problem of mercury use, which has been a problem in the traditional mercury lamp, and to emit the light effectively with a small power.

[0071] Because UVA is relatively inexpensive, it is cost-effective, allowing it to effectively activate the photocatalytic reaction of the catalyst section 130. UVC is relatively expensive, but it can activate the photocatalytic reaction while simultaneously performing its own sterilization function, thus improving sterilization efficiency.

[0072] For reference, the light source section 120 may consist of one or more light sources, and is not limited to a specific number.

[0073] The first wavelength range in accordance with the present embodiment has the light quantity P kept in a range of 180 nm to 360 nm, wherein the radiation in a range of the above-described first wavelength range is carried out selectively to the catalyst portion 130.

[0074] For the first wavelength range, for example, the amount of light P in any range of the above-described range may be radiated to the catalyst portion 130, in which case the efficiency can be kept excellent so that the above-described amount of light is radiated to the catalyst portion 130.

[0075] The light source section 120 may consist of one or more LEDs, in which case several of the same LEDs may be provided therein.

[0076] The light source section 120 can be configured so that the LEDs emitting ultraviolet light and visible light simultaneously. In this case, due to the different wavelengths, the optical energy is concentrated on the catalyst section 130, thus improving efficiency.

[0077] The second wavelength range in accordance with the present embodiment has a light quantity P kept in a range of 380 nm to 760 nm, wherein the radiation in a range of the above-described second wavelength range is carried out selectively to the catalyst portion 130.

[0078] In addition, according to the present embodiment, the second wavelength range may have the light quantity P kept within a range of 400 nm to 500 nm. In this case, the radiation in a range of the above-described second wavelength range is carried out selectively to the catalyst portion 130.

[0079] In Fig. 6, the present embodiment includes a reflection plate 160 disposed on the inside of the housing 140 so as to face the light source portion 120 to reflect the light source emitted from the light source portion 120 to the catalyst portion 130. The reflection plate 160 is located at a position between 2 / 3 * P and 1 / 3 * P based on the optical quantity P.

[0080] The reflection plate 160 may be arranged to be perpendicular to the catalyst portion 130, or may be arranged to be inclined at an angle of less than 5 degrees, and is not limited to the state illustrated in the figure.

[0081] The catalyst section 130 according to the present embodiment generates peroxide radicals through the photocatalytic reaction using the light emitted by the light source section 120. The catalyst section 130 generates the photocatalytic reaction using the light emitted by the light source section 120 and removes contaminants and fungi introduced into the air conditioning case 300, various contaminants, and odors in the evaporator 410 due to the oxidizing effect of the peroxide radicals generated by the photocatalytic reaction.

[0082] When the catalyst portion 130 absorbs the light emitted from the light source portion 120, the electrons of the valence band (VB) filled with electrons absorb the light energy to move to the conduction band (CB) where the electrons are empty.

[0083] A hole, which is an empty electron site in the valence band, oxidizes the water molecules on the surface, with the oxidized water molecules becoming OH radicals.

[0084] In addition, the electrons excited by the conduction band, called excited electrons, react with the oxygen to generate the peroxide radicals, which have strong acidic power and sterilize the vaporizer 410.

[0085] The catalyst portion 130 according to the present embodiment has the air porosity maintained at 80% or more and the thickness of 5 mm to 50 mm.

[0086] The weight of the catalyst contained in the catalyst section 130 is maintained within a range of 10% to 30% of the total weight of the catalyst section 130. The catalyst consists of titanium oxide particulated to a size of 10 nm to 60 nm.

[0087] The titanium oxide (TiO2) receives the ultraviolet ray of 400 nm or smaller to generate peroxide radicals, the generated peroxide radicals decompose the organic substance into safe water and carbon dioxide.

[0088] The titanium oxide is nano-encapsulated to generate a large amount of peroxide radicals, even when using a light source with a relatively weak ultraviolet wavelength.

[0089] Accordingly, it exhibits excellent decomposition ability of organic matter, exhibits long-lasting durability and stability against environmental changes, and exhibits a semi-permanent effect. In addition, the large amount of peroxide radicals generated can remove not only organic matter but also various substances, such as odors and bacteria.

[0090] The catalyst section 130 forms a surface area of ​​the nano-encapsulated titanium oxide of 330 m2 / g or more, so that the number of particles receiving the optical energy per equal area is much larger than that of general titanium oxide, in order to increase the amount of peroxide radicals generated.

[0091] A graph illustrating the deodorization state with respect to elapsed time by the catalyst device according to the first embodiment of the present disclosure will be described with reference to Fig. 7. For reference, the X-axis represents the elapsed time, while the Y-axis represents the deodorizing concentration.

[0092] If in Fig. 7, the catalyst portion 130 according to the present embodiment is spaced the first distance L from the light source portion 130, the deodorizing concentration is illustrated as a function of elapsed time in the graph of the figure.

[0093] As described above, even with the size reduction, when the deodorization for the evaporator is carried out by the catalyst section 130, the deodorization rate can be kept at 81.2% and the efficiency can be kept excellent.

[0094] An air conditioning device for a vehicle having a catalyst device according to another embodiment of the present disclosure will be described with reference to the drawings.

[0095] In Fig. 8, an air conditioning device for a vehicle 1000 includes the air conditioning case 300, the evaporator 410, a heater core 420, and the catalyst device 100.

[0096] The air conditioning case 300 transmits the air flowing therein, forms the space in which the evaporator 410 and the heater core 420 are mounted, and forms a vent opening 310 through which the air is discharged.

[0097] More specifically, the air conditioning case 300 is formed with the vent opening 310 through which the temperature-controlled air is discharged into the vehicle through the evaporator 410 and the heater core 420.

[0098] The vent opening 310 includes a front vent opening 310, a defroster vent opening 310 and a floor vent opening 310.

[0099] The front vent 310 discharges the air to the front (front seat) of the vehicle interior, the defroster vent 310 discharges the air to the windshield of the vehicle interior, and the floor vent 310 discharges the air to the floor of the front seat of the vehicle interior, wherein the openings of the front vent 310, the defroster vent 310, and the floor vent 310 are adjusted by the respective mode doors 310d.

[0100] A fan 214 for blowing air may be provided on the air inlet side of the air conditioning case 300, and an inside air inlet 211 and an outside air inlet 212 can be selectively opened or closed by an inside air / outside air switching door 213, so that when the fan 214 is operated, the inside air or the outside air is transmitted to the air conditioning case 300.

[0101] The inside air inlet 211 communicates with the vehicle interior to allow the inside air to flow in, while the outside air inlet 212 communicates with the outside of the vehicle to allow the outside air to flow in.

[0102] The inside air / outside air switching door 213 is provided within an inflow duct to open / close the inside air inlet 211 and the outside air inlet 212, and the inside air / outside air switching door 213 operates depending on the attitude of the occupants in the vehicle to control that the outside air or the inside air selectively flows thereinto.

[0103] The evaporator 410 cools the air by the flow of the cold refrigerant, while the heater core 420 heats the air by the flow of the heated refrigerant, wherein the evaporator 410 and the heater core 420 are provided sequentially in the air flow direction.

[0104] In addition, the air conditioning case 300 is provided with a temperature control door 320 for determining the degree of air from the evaporator 410 through the heater core 420.

[0105] That is, the temperature control door 320 controls the opening of the warm air passage so that all the air passing through the evaporator 410 passes through the heater core 420 and the cold air passage that does not pass through the heater core 420.

[0106] At this time, the catalyst device 100 has the characteristics described above, and it can be provided at the front of the evaporator 410 in the air flow direction to sterilize and deodorize the evaporator 410.

[0107] In addition, the catalyst device 100 is provided on the back side of the evaporator 410 in the air flow direction to sterilize and deodorize the evaporator 410, and also the peroxide radicals generated in the catalyst device 100 flow into the vehicle to perform air purification in the vehicle interior.
