In Japanese Unexamined Patent Publication No. 9-322933, a cylindrical lamp is arranged on the side surface of the deodorizing filter to reduce the thickness in the direction of the ventilation passage. However, the technique disclosed in the above publication requires a space for disposing the cylindrical lamp on the side portion of the deodorizing filter, resulting in an increase in size. Further, the air flow is easily bypassed (short circuit) between the deodorizing filter and the cylindrical lamp, and the dust collection effect is reduced.

小型化を図ることは困難である。It is considered that when the filter is folded in a pleat shape to increase the filter area, the life of the filter is extended and the dust collection efficiency and the deodorization efficiency are increased. However, it is considered that folding the filter into pleats can extend the life of the dust collecting filter and improve the dust collecting efficiency, while the light that activates the photocatalyst is applied to the entire surface of the deodorizing filter with pleats. Irradiation becomes difficult. Therefore, the deodorizing filter has a portion that does not receive light irradiation and does not sufficiently act as a catalyst, and the deodorizing efficiency is rather reduced. Further, by folding the deodorizing filter into pleats, the thickness of the filter is increased, and since the space for disposing the light irradiation light source is secured, the direction of the air passage becomes thick. Therefore, it is difficult to reduce the size of the entire deodorizing device while ensuring a long service life of the filter and high efficiency of dust collection and deodorizing.

低下が生ずるからである。In the present invention, the recess is for embedding the tubular light source in order to make the distance between the deodorizing filter and the tubular light source as close as possible. Therefore, the size and depth of the depression are necessary and sufficient to be able to embed the tubular light source, and the tubular light source cannot be embedded if the size is small or the depth is shallow, while it is large or the depth is deep. It becomes impossible to irradiate light on the entire surface of one side of the deodorizing filter and the narrowing of the filter area. Furthermore, it is important that the depression of the present invention is a depression that does not have a bypass portion that causes air leakage. When the bypass portion is formed to form the depression, it is necessary to close the opening or fold the pleat without forming the opening to form the depression. This is because the deodorization efficiency is reduced if there is a bypass section.

減につながる。The photocatalyst deodorizing apparatus 100 according to the present invention can employ any of the filter units shown in FIGS. 2 (a) to 2 (d), but the forms shown in FIGS. 2 (a) and 2 (b) are not suitable for collecting dust. It is preferable because the total thickness of the filter and the deodorizing filter can be reduced. Further, the form of FIG. 2B is most preferable because the dust collecting filter and the deodorizing filter can be replaced according to their lives. According to the actual mounting test, in the form of FIG. 2A, the dust collecting function deteriorates after 400 hours (equivalent to one year use), and replacement is required. However, the deodorizing function is maintained at 60% due to the action of the photocatalyst. Therefore, the deodorizing filter that can still be used is wasted. If the photocatalyst is not used, the deodorizing function will be reduced in 400 hours (equivalent to one year use) and replacement will be required. On the other hand, in the configuration of FIG. 2B, it is possible to replace the dust collecting filter and the deodorizing filter in accordance with their respective lives, and the dust collecting filter is replaced for 400 hours (equivalent to one year use), and the deodorizing filter is replaced with 1200. Time (equivalent to 3 years use)
Replace with. Therefore, by adopting the configuration of FIG. 2B, it is possible to take advantage of the feature of extending the life of the deodorizing filter by the photocatalyst. That is, since the dust collecting filter and the deodorizing filter can be separately attached and detached, the frequency of exchanging the deodorizing filter can be reduced, which leads to a reduction in the expense of the vehicle owner.

The dust collecting filter 32 has a dust collecting function of capturing dust in the air, and the filter material is not particularly limited, but a paper material,
It is formed of a fibrous material such as a resin material. Further, it is preferably a non-woven fabric such as a resin. By the way, in the present invention, the deodorizing filter is provided with a cutout-shaped recess that closes the opening or a pleated recess. In order to make the space in the thickness direction where the deodorizing filter and the dust collecting filter overlap each other as thin as possible, that is, to prevent the depression of the deodorizing filter from coming into contact with the dust collecting filter and hindering the thinning in the thickness direction. It is preferable to provide the dust filter with a recess having the same shape as the recess of the deodorizing filter at the same position. As with the deodorizing filter, it is preferable that the recess provided in the dust collecting filter be a recess having a cutout shape that closes the opening or a recess having a pleat folded shape. As a method of closing the opening, it is preferable to integrally mold the resin and the filter so that the resin film closes the opening of the filter. By closing the opening, it is possible to prevent leakage of the air flow, that is, bypass. Further, when the filter material is a non-woven fabric, it is preferable that the non-woven fabric is applied to a mold having a filter shape having a notch and the non-woven fabric is used as a dust collecting filter. In this case, since the cutout portion can also be made of a non-woven fabric, a reduction in the filter area does not occur as compared with closing the opening portion due to the cutout with resin, which is preferable. The optimum filter diameter is selected from the relationship between dust collection efficiency and ventilation resistance, and the present invention is not limited to the filter diameter. The material of the frames 34, 37a, 38 is not particularly limited, but those made of resin such as polypropylene are preferable.

The deodorizing filter 33 has a function of adsorbing and removing odorous substances from the air after the dust collecting filter 32 has captured the dust in the air. The filter base material is formed using a fibrous material such as a paper material and a resin material similar to those of the dust collecting filter. Further, it is preferably a non-woven fabric. The filter diameter is
The optimum one is selected from the relationship between the dust collection / deodorization efficiency and the ventilation resistance, and the present invention is not limited to the filter diameter. An adsorbent powder such as activated carbon, zeolite, or silica gel is mixed with this filter base material, and a photocatalyst made of a metal oxide powder such as titanium oxide or zinc oxide is further supported. The adsorbent powder is preferably activated carbon. The photocatalyst is mixed with an adsorbent, and examples of the mixing method include a spray method and a method of mixing with the adsorbent. As described above, in order to secure a space for embedding the tubular light source, the deodorizing filter is provided with a cutout-shaped recess that closes the opening or a pleat-shaped recess. As a method of closing the opening, it is preferable to integrally mold the resin and the filter so that the resin film closes the opening of the filter.
By closing the opening, it is possible to prevent airflow from leaking. Further, when the filter material is a non-woven fabric, it is preferable that the non-woven fabric is applied to a mold having a filter shape having a notch and the non-woven fabric is used as a dust collecting filter. In this case, since the cutout portion can also be made of a non-woven fabric, a reduction in the filter area does not occur as compared with closing the opening portion due to the cutout with resin, which is preferable. The material of the frames 34, 37b, 39 is not particularly limited, but those made of resin such as polypropylene are preferable. When the photocatalyst of the deodorizing filter 33 is irradiated with ultraviolet rays from the tubular light source 35, OH radicals are generated from the adsorbed water. Due to the strong oxidizing power of the OH radicals, the odorous substance adsorbed on the adsorbent of the filter 33 is decomposed and the adsorbent is regenerated.

The tubular light source may be any light source for activating the photocatalyst, and a type of light source that radiates visible light to ultraviolet rays or only ultraviolet rays is used. Specifically, the tubular light source 35 may be a mercury lamp, a cathode tube (CFL), a black light, a cold cathode tube (CCFL), or a xenon outer electrode lamp. The tubular light source according to the present invention refers to the above-mentioned tubular lamp.

水銀量の関係を示した。In the present invention, the tubular light source 35 is particularly preferably a xenon outer electrode lamp. In recent years, the use of mercury has been reduced due to environmental pollution,
This is because the same measures are needed for ultraviolet lamps. In this respect, the light emitting diode can also be used as an ultraviolet light source without using mercury, but the intensity of ultraviolet light per light emitting diode is weak, and it is necessary to arrange many light emitting diodes. On the other hand, the xenon external electrode lamp is structurally incapable of 360-degree full-angle emission, but the emission angle of the light can be adjusted, so that only the deodorizing filter can be efficiently irradiated, and the ultraviolet irradiation of other members can be performed. It is also possible to prevent deterioration. Table 2 shows the relationship between various lamps and the amount of mercury.

The tubular light source 35 may have a radiation angle equal to or larger than the one surface of the deodorizing filter 33 that can irradiate the entire surface. This is because the tubular light source 35 irradiates ultraviolet rays and deteriorates other members. In a tubular light source having a 360 ° omnidirectional radiation angle, it is preferable to provide a reflection plate (not shown) and adjust the radiation angle so that only one side of the deodorizing filter 33 can be entirely illuminated.

On the other hand, if it is longer than the width of the deodorizing filter, the portion where the tubular light source projects from the width of the deodorizing filter This is because space is required and the device becomes large.

得られる。The case where a xenon outer electrode lamp is used as the tubular light source 35 will be described in detail. The xenon external electrode lamp does not have an electrode inside the lamp, but an electrode is provided outside to discharge the internal gas. In the xenon outer electrode lamp of the present invention, at least one electrode is provided on the outer surface of the lamp. FIG. 5C shows a structural schematic view of a cross section of the xenon outer electrode lamp, which is the tubular light source 35, taken along the line AA ′. Two external electrodes 51 are arranged outside the glass tube 50 in parallel with the tube axis, and a fluorescent material 52 is applied to the inside of the glass tube, which is a dielectric material, and the fluorescent material in the portion just between the external electrodes 51 is removed. An aperture 53 is provided and light is extracted from the aperture 53. As the filling gas, pure xenon or a rare gas mixed gas mainly containing xenon is used, and mercury for the purpose of causing the phosphor to emit light is unnecessary. When a high frequency high voltage is applied to the outer electrode 51 of the xenon outer electrode lamp, dielectric polarization occurs in the glass, which is a dielectric, and a high voltage is generated inside the lamp. Discharge starts when the xenon gas in contact with the glass reaches the breakdown voltage. Immediately, the ions and electrons in the plasma move to the negative electrode side and the anode side, respectively, so that the voltage in the plasma sharply drops and the discharge ends in a short time (approximately several tens of ns). This discharge is a fine discharge with a diameter of about 0.1 mm, but a large number of discharges occur when the conditions of discharge breakdown are satisfied on the glass surface between the external electrodes 51. After a series of micro discharges,
In case of high frequency lighting, the charge on the dielectric surface inside the lamp is
By applying a reverse voltage, the external electrodes 51 and the glass are electrically neutralized. However, the electric charge on the inner surface of the glass of the lamp remains, and at the reverse voltage, a fine discharge is generated below the initial discharge breakdown voltage with the help of the residual electric charge on the inner surface of the glass, and so on. The xenon external electrode lamp has higher efficiency than the conventional internal electrode type lamp.

すれば良い。The xenon outer electrode lamp has a structure in which light is extracted from the aperture 53 at an angle θ as described above, and the angle of the aperture 53 is substantially equal to the irradiation angle of the ultraviolet light of the tubular light source 35. Therefore, when a xenon external electrode lamp is used as the tubular light source 35,
As shown in FIGS. 5A and 5B, the angle of the aperture 53 is adjusted so that the tubular light source 35 matches the radiation angle θ with which one surface of the deodorizing filter can be entirely irradiated. The tubular light source 35 shown in FIG. 5 is arranged near one end of the deodorizing filter 35. However, when the tubular light source 35 is arranged at the center of the filter, the radiation angle θ that can irradiate the entire surface of one side of the deodorizing filter changes. Therefore, the angle of the aperture 53 may be adjusted accordingly.
