  An object of this invention is to provide the deodorizer which can improve a deodorizing performance by making ozone deodorizing process efficient.

In order to achieve the above object, a deodorizer according to the present invention is a deodorizer for performing a deodorization treatment of air, and has an air suction port and a discharge port, and an air passage connecting the suction port and the discharge port. And an ozone deodorizing unit that is disposed on the air passage and deodorizes the air with ozone, and a blower that circulates air into the air passage, and the ozone deodorizing unit includes: a casing which constitutes the reaction space between the air and ozone, and having a ozone generator for generating ozone within the case, have a turbulence generating structure for generating a turbulent flow of air into the case, the turbulent flow generating structure is constituted by the baffle body a inlet portion disposed in the flow path of air in the casing, wherein the rectifying unit for rectifying the flow of air is arranged upstream of the baffle member

In this deodorizer, since the ozone deodorizing part has a turbulent flow generating structure that generates turbulent air flow in the case, the reaction between air and ozone in the case is favorably performed. Thereby, since the deodorizing process in an ozone deodorizing part is performed effectively, there exists an advantage which the deodorizing performance of a deodorizer improves.
Moreover, in this deodorizer, air collides with a baffle in a case, and a turbulent flow is formed in a case (near ozone generation part). Thereby, since reaction with the air and ozone in a case is accelerated | stimulated, there exists an advantage which the deodorizing performance of a deodorizer improves.
Moreover, in this deodorizer, since the rectification | straightening part rectifies | swells air in the upstream of a baffle, the bias | biasing of the air in a baffle is reduced. Thereby, the favorable eddy of air is formed in a case, reaction of the air and ozone in a case is accelerated | stimulated, and there exists an advantage which the deodorizing performance of a deodorizer improves further.
In the deodorizer according to the present invention, the ozone generator is disposed in the vicinity of the baffle.

  In the deodorizer according to the present invention, the turbulent flow generation structure of the ozone deodorization unit is configured by the air inflow direction and the outflow direction in the case being on different straight lines.

  In this deodorizer, the inflow direction and the outflow direction of air in the case of the ozone deodorization part are on different straight lines (turbulent flow generation structure). That is, in the case, the air inflow direction and the outflow direction are configured not to be in a straight line. In such a configuration, air that has flowed into the case passes through the flow path from the inlet portion toward the outlet portion, so that air and ozone are compared with a configuration in which air passes through the case linearly. The reaction is performed satisfactorily. Thereby, since the deodorizing process in an ozone deodorizing part is performed effectively, there exists an advantage which the deodorizing performance of a deodorizer improves.

  In the deodorizer according to the present invention, the baffle has a rib-like structure and has fins in the rib-like portion.

  In this deodorizer, a turbulent flow is efficiently formed in the case by the fins, and the reaction between air and ozone in the case is promoted. Thereby, there exists an advantage which the deodorizing performance of a deodorizer improves further.

  Further, in the deodorizer according to the present invention, the baffle fin is formed of a substantially arc-shaped protrusion or notch.

  In this deodorizer, a three-dimensional vortex is generated in the case by the air flowing into the case hitting the baffle fins. Thereby, reaction with the air and ozone in a case is accelerated | stimulated and there exists an advantage which the deodorizing performance of a deodorizer improves further.

  Moreover, the deodorizer concerning this invention is comprised by the guide part which the turbulent flow generation structure of the said ozone deodorizing part guides the air in the said case, and generates a vortex | eddy_current in the said case.

  In this deodorizer, the air in the case is guided by the guide portion and a vortex is generated in the case, so that the reaction between the air and ozone in the case is promoted. Thereby, there exists an advantage which the deodorizing performance of a deodorizer improves further.

  In the deodorizer according to the present invention, the ozone generating part is an ultraviolet lamp, and a photocatalyst is applied to the guide part.

  In this deodorizer, decomposition of odors in the air in the case is promoted by the photocatalyst in the guide portion. Thereby, since decomposition | disassembly of the odor in air is accelerated | stimulated, there exists an advantage by which the deodorizing process of air is performed efficiently.

  In the deodorizer according to the present invention, the ozone generating unit is an ultraviolet lamp, and the case has an ultraviolet blocking structure for suppressing leakage of ultraviolet rays from the inside.

  In this deodorizer, ultraviolet rays are blocked by the ultraviolet blocking structure, and leakage of ultraviolet rays from the ozone deodorizing part (case) is suppressed. Thereby, there exists an advantage by which the bad influence to the human body by ultraviolet rays or deterioration of a housing | casing etc. is suppressed.

  In the deodorizer according to the present invention, since the inflow direction and the outflow direction of air in the case of the ozone deodorization part are on different straight lines, the air flowing into the case bends the flow path from the inlet part toward the outlet part. And pass. For this reason, compared with the structure which air passes the inside of a case linearly, reaction of air and ozone is performed favorably. Thereby, since the deodorizing process in an ozone deodorizing part is performed effectively, there exists an advantage which the deodorizing performance of a deodorizer improves.

  Hereinafter, the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

[Deodorizer]
This deodorizer 1 is installed indoors to reduce odors in the room (odors spread in the room, odors on walls and furniture, odors of body odors etc. that occur all the time) and reduce discomfort caused by odors. It has the function to do. The deodorizer 1 is installed in, for example, living spaces of general households and elderly facilities, toilets, filth rooms, corridors, hospital waiting rooms and hospital rooms, clinic treatment rooms, pet hotels, animal hospital waiting rooms and treatment rooms, and the like. . In addition, this deodorizer 1 may be mounted, for example in an air conditioner, an air cleaner, etc. (illustration omitted).

  The deodorizer 1 includes a housing 2, an adsorption deodorization unit (adsorption unit) 3, an ozone deodorization unit (ozone decomposition unit) 4, a blower 5, and a control unit 6 (see FIGS. 1 and 2). . The housing | casing 2 consists of a resin-made member, and has the box-shaped shape which can stand up on a floor surface. The housing 2 has a suction port 21 on its side (surface perpendicular to the floor surface in the installed state) and a discharge port 22 on its top. In addition, an air passage R extending from the suction port 21 to the discharge port 22 is formed inside the housing 2. And the adsorption deodorizing part 3, the ozone deodorizing part 4, and the air blower 5 are arrange | positioned on this air path R. FIG.

  The adsorption deodorizing unit 3 has a function of adsorbing dust and gaseous odor in the air. The adsorption / deodorization unit 3 is disposed on the air passage R in the housing 2 and in the vicinity of the suction port 21 of the housing 2. The dust in the air refers to, for example, coarse dust or smoke odor (fine particles) in the air. The gaseous odor in the air means, for example, sulfur odor such as garbage odor and fecal odor, aldehyde odor such as sweat odor and building material odor, fatty acid odor such as body odor, ammonia odor such as manure odor, etc. .

  The adsorption / deodorization unit 3 includes, for example, a dust collection filter 31, a catalyst filter 32, and an activated carbon filter 33, and has a three-layer structure in which these are stacked (see FIGS. 2 to 4). Moreover, these deodorizing filters 31 to 33 are arranged and stacked in the order of the dust collection filter 31, the catalyst filter 32, and the activated carbon filter 33 from the upstream side.

  The dust collection filter 31 has a pleated structure and a function of collecting coarse dust, smoke odor (fine particles), and the like in the air. The catalyst filter 32 has a function of adsorbing and decomposing a gaseous odor in the air. The catalyst filter 32 is constituted by, for example, a filter containing zeolite having ammonia adsorption characteristics, a filter containing a metal oxide having formaldehyde decomposition characteristics, or the like. The activated carbon filter 33 has a function of temporarily storing the decomposition residue of the gaseous odor in the air that has passed through the catalyst filter 32. The activated carbon filter 33 is, for example, a honeycomb-structured filter filled with activated carbon, activated carbon to which a chemical having a chemical adsorption characteristic of an aldehyde odor is added, or a chemical having a chemical adsorption characteristic of a basic odor such as ammonia. Is composed of activated carbon and the like. The activated carbon filter 33 is attached with a catalyst having an action of decomposing sulfur odor.

  In addition, this adsorption | suction deodorizing part 3 can be easily attached or detached with respect to the housing | casing 2, and the deodorizing filters 31-33 are comprised so that isolation | separation is mutually possible. For this reason, there is an advantage that the dust collection filter 31 can be taken out and easily cleaned. Moreover, the dust collection filter 31 is configured by heat-welding a core-sheath structure fiber made of polypropylene and polybutene, for example, and has improved water-washing performance. For this reason, there is an advantage that the replacement life of the dust collection filter 31 is long.

  The ozone deodorizing unit 4 has a function of decomposing odors in the air with ozone (see FIGS. 5 and 6). The ozone deodorizing unit 4 is disposed on the air passage R in the housing 2 and downstream of the adsorption deodorizing unit 3 (near the discharge port 22 of the housing 2). The ozone deodorization unit 4 includes a case 41 and an ozone generation unit 42. The case 41 is a box-shaped member made of a non-ultraviolet material (for example, a metal material), and constitutes a reaction space between air and ozone. The case 41 has an air inlet 411 and an outlet 412. The ozone generator 42 has a function of generating ozone in the case 41, and is configured by, for example, an ultraviolet lamp. The ozone generator 42 is disposed near the inlet 411 of the case 41.

  A photocatalyst is disposed in the ozone deodorizing unit 4. Specifically, a photocatalyst (for example, titanium oxide) is applied to the inner wall surface of the case 41 and the like. When the photocatalyst is irradiated with ultraviolet rays, hydroxyl radicals are generated in the case 41. Since this hydroxyl radical has a higher oxidative decomposition ability than ozone, it is effective in decomposing ammonia odor that is difficult to decompose with ozone.

  Note that the ozone generator 42 composed of an ultraviolet lamp (1) is less susceptible to the influence of room temperature, humidity, or atmospheric pressure, so that the amount of ozone generated can be kept constant. (2) Abnormal discharge due to dust in the air (3) Does not generate harmful substances such as nitrogen oxides, (4) Oxygen radicals with strong sterilization lines and oxidative decomposition power are generated, which is preferable in terms of having a high contribution to deodorization.

  The blower 5 has a function of circulating air through the air passage R by blowing air. The blower 5 is configured by, for example, a sirocco fan, and is disposed on the downstream side of the adsorption deodorizing unit 3 and the upstream side of the ozone deodorizing unit 4.

  The control unit 6 performs drive control of the heating means 34 of the adsorption deodorization unit 3 described later, drive control of the ozone generation unit 42 of the ozone deodorization unit 4, drive control of the blower 5, and other control necessary for driving the deodorizer 1. Do.

[Operation of deodorizer]
In this deodorizer 1, when the blower 5 is driven during operation, indoor air is sucked from the suction port 21 and passes through the adsorption deodorization unit 3 (see FIGS. 2, 4 and 7). In this adsorption deodorization part 3, the deodorizing process of a high concentration odor is performed and strong odor in the air is removed. Specifically, first, the dust collection filter 31 of the adsorption deodorizing unit 3 collects coarse dust, smoke odor, and the like in the air. Next, the gaseous odor in the air is adsorbed and decomposed by the catalyst filter 32. Next, the activated carbon filter 33 temporarily accumulates the decomposition residue of the gaseous odor in the air that has passed through the catalyst filter 32.

  In addition, when the catalyst filter 32 and the activated carbon filter 33 have a honeycomb structure, gaseous odors in the air passing through them are efficiently adsorbed. Further, since the adsorbed gaseous odor is decomposed in the catalyst filter 32, accumulation of odor components is suppressed. Thereby, since the saturation of the odor component in the catalyst filter 32 is delayed, there is an advantage that the replacement life of the filter (adsorption deodorization unit 3) is extended.

  Next, air is sent to the ozone deodorization part 4 through the air blower 5 (refer FIG.2, FIG.6 and FIG.7). In the ozone deodorizing unit 4, a deodorizing process for low-concentration odors in the air is performed, and minute odors in the air that were not removed by the adsorption deodorizing unit 3 are removed. Specifically, in the case 41 of the ozone deodorizing unit 4, the ozone generated by the ozone generating unit 42 reacts with air, and the air is deodorized. Further, in the ozone deodorizing unit 4, hydroxyl radicals are generated in the case 41 when the photocatalyst in the case 41 is irradiated with ultraviolet rays. And the odor in air is decomposed | disassembled by this hydroxyl radical, and the deodorizing process of air is performed.

  Next, the air that has passed through the ozone deodorizing unit 4 is released into the room through the discharge port 22 of the housing 2 and is reduced. This air is in a state close to odorless by the deodorizing process in the adsorption deodorizing unit 3 and the ozone deodorizing unit 4.

  Here, the air reduced indoors contains low-concentration ozone. This low-concentration ozone is mixed with air in the ozone deodorizing unit 4 and released into the room together with the deodorized air. This low-concentration ozone breaks down odors that stain the indoor walls, sofas, furniture, clothes, and so on.

[Effect of deodorizer]
The deodorizer 1 includes an adsorption deodorizing unit 3 that adsorbs odors in the air and deodorizes the air, and an ozone deodorizing unit 4 that deodorizes the air with ozone, and the adsorption deodorizing unit 3 and The air deodorized by the ozone deodorizing unit 4 is discharged to the outside (for example, indoors) from the discharge port 22 together with ozone (low concentration ozone) (see FIG. 7). In such a configuration, after the high concentration odor in the air is adsorbed by the adsorption deodorization unit 3 (catalyst filter 32 and activated carbon filter 33) and the low concentration odor in the air is adsorbed by the ozone deodorization unit 4, this deodorization treatment is performed. The released air is released to the outside. Thereby, since the deodorizing process of air is performed suitably, there exists an advantage which the deodorizing performance of the deodorizer 1 improves (refer FIG. 8). In addition, since low-concentration ozone is released to the outside together with the deodorized air, the low-concentration ozone effectively decomposes odors that permeate the installation space of the deodorizer 1 (for example, indoor walls and furniture). There is an advantage of being removed (see FIG. 8). Moreover, since the masking effect of odor is acquired by the low-concentration ozone released, there is an advantage that the user can obtain a odorless sensation.

  Moreover, in this deodorizer 1, the ozone deodorizing part 4 is arrange | positioned in the downstream of the adsorption | suction deodorizing part 3 (refer FIG. 2 and FIG. 7). In such a configuration, first, the high-concentration odor in the air is adsorbed and deodorized by the adsorption / deodorization unit 3, and then the low-concentration odor in the air is deodorized by ozone in the ozone deodorization unit 4. Thus, there is an advantage that an efficient deodorizing process is realized by performing the removal step by step from the high concentration odor to the low concentration odor. For example, in the configuration in which the deodorizing process for the low concentration odor is performed first, the high concentration odor is not sufficiently removed.

  Moreover, in this deodorizer 1, the adsorption | suction deodorization part 3 has the catalyst filter 32 which adsorb | sucks and decomposes | disassembles the gaseous odor in air (refer FIG. 3 and FIG. 4). In such a configuration, the adsorbed gaseous odor is decomposed by the catalyst filter 32, so that accumulation of the gaseous odor is suppressed. Thereby, there exists an advantage which the replacement life of a filter (adsorption deodorizing part 3) extends. Moreover, in this structure, since odor can be decomposed | disassembled, performing ventilation continuously, compared with the structure (illustration omitted) which needs to stop ventilation in order to decompose | disassemble odor, indoor deodorization is performed efficiently. Thereby, there exists an advantage which the deodorizing performance of the deodorizer 1 improves further. In particular, such a configuration effectively decomposes odors that are constantly generated, such as odors and body odors that have permeated indoor walls.

  Moreover, in this deodorizer 1, the adsorption | suction deodorizing part 3 has the activated carbon filter 33 in the downstream of the catalyst filter 32 (refer FIG. 3 and FIG. 4). In such a configuration, since the decomposition residue of the gaseous odor in the air that has passed through the catalyst filter 32 is temporarily stored in the activated carbon filter 33, the decomposition residue of the gaseous odor is adsorbed without leakage. Thereby, there exists an advantage which the deodorizing performance of the deodorizer 1 improves further (refer FIG. 8 and FIG. 9).

  Further, in this deodorizer 1, the ozone deodorizer 4 has a photocatalyst and an ultraviolet lamp (ozone generator 42) for irradiating the photocatalyst with ultraviolet rays, and the odor in the air is decomposed by the photocatalyst. There is an advantage that the deodorizing performance is further improved (see FIGS. 8 and 9).

[Heating means]
In addition, in this deodorizer 1, it is preferable that the adsorption | suction deodorizing part 3 has the heating means 34 which heats the catalyst filter 32 (refer FIG. 2, FIG. 3). The heating means 34 is constituted by, for example, a cord heater, a sheathed heater, or the like, and is arranged so as to contact the catalyst filter 32 directly or indirectly via an intermediate member (heat transfer member 342). Yes.

  In such a configuration, the catalyst filter 32 is heated by the heating means 34 when the deodorizer 1 is in operation. Thereby, since decomposition | disassembly of the gaseous odor adsorbed by the catalyst filter 32 is accelerated | stimulated, there exists an advantage which the deodorizing performance of the deodorizer 1 improves. Moreover, in this structure, since decomposition | disassembly of gaseous odor is accelerated | stimulated, without stopping ventilation, the odor which generate | occur | produces continuously continuously is decomposed | disassembled effectively. Thereby, there exists an advantage which the deodorizing performance of the deodorizer 1 improves further. Moreover, since accumulation of the gaseous odor in the catalyst filter 32 is suppressed by this, there exists an advantage which the replacement life of a filter (adsorption | suction deodorizing part 3) extends.

  Further, in the above configuration, it is preferable that the heating means 34 has a bendable structure and is arranged so as to be routed on the catalyst filter 32 (upstream side or downstream side of the catalyst filter 32) (see FIG. 3). . For example, the heating means 34 is composed of a cord heater and is arranged so as to meander over substantially the entire area of the catalyst filter 32. In such a configuration, it is possible to heat substantially the entire area of the catalyst filter 32 by one or a small number of heating means (code heaters) 34. Thereby, there is an advantage that the catalyst filter 32 can be effectively heated by the simple heating means 34 and the deodorizing performance of the deodorizer 1 can be improved.

  In the configuration described above, it is preferable that the meandering interval (pitch applied to the bellows arrangement) of the heating means 34 is appropriately defined so as not to hinder ventilation.

  The heating means 34 is preferably disposed in close contact with the catalyst filter 32 (see FIG. 10). For example, it is preferable that the heating means 34 is held by a rigid heater frame 341 and the heating means 34 is directly or indirectly biased to the catalyst filter 32 by the heater frame 341. The heater frame 341 has, for example, a plurality of claw portions (not shown), and the heating means 34 is held in a curved state by these claw portions and pressed against the catalyst filter 32. In such a configuration, the degree of adhesion between the heating means 34 and the catalyst filter 32 is increased, so that the catalyst filter 32 is efficiently heated. Thereby, there exists an advantage which the decomposition performance of the gaseous odor by the catalyst filter 32 improves.

  Further, in such a configuration, it is preferable that the heat transfer member 342 having heat conduction characteristics is sandwiched between the heating means 34 and the catalyst filter 32 (see FIG. 10). That is, the heating means 34 is disposed in close contact with the catalyst filter 32 via the heat transfer member 342. The heat transfer member 342 is made of, for example, a metal or polypropylene mesh material. In such a configuration, efficient heat transfer from the cord heater 34 to the catalyst filter 32 via the heat transfer member 342 is realized. Thereby, since heating of the catalyst filter 32 is performed efficiently, there exists an advantage which the decomposition performance of the gaseous odor by the catalyst filter 32 improves. Further, since the direct frictional contact between the heating means 34 and the catalyst filter 32 is suppressed by the heat transfer member 342, there is an advantage that the disconnection of the code heater 34 is effectively suppressed.

  In the configuration described above, in the configuration in which the heating means 34 is a sheathed heater (not shown), the heating means 34 is arranged so as to be in direct contact with the catalyst filter 32 without the heat transfer member 342 being interposed. May be. Thereby, since more efficient heat transfer is performed, there exists an advantage by which the decomposition | disassembly effect | action of the catalyst filter 32 is activated more.

  In the above configuration, it is preferable that the heating means 34 is disposed on the upstream side of the catalyst filter 32 (see FIGS. 4 and 10). Thereby, since the heat of the heating means 34 is efficiently transmitted to the catalyst filter 32 (and also the activated carbon filter 33), there is an advantage that the decomposition performance of the gaseous odor by the catalyst filter 32 is improved.

  Moreover, in said structure, it is preferable that the activated carbon filter 33 is arrange | positioned adjacent to the downstream of the catalyst filter 32 (refer FIGS. 2-4). In such a configuration, since the heat of the heating means 34 is transmitted to the activated carbon filter 33 via the catalyst filter 32, the activated carbon filter 33 is also heated together with the catalyst filter 32. Thereby, there exists an advantage by which the reproduction | regeneration of the activated carbon filter 33 is performed. In such a configuration, the decomposition residue of the gaseous odor in the air that has passed through the catalyst filter 32 is temporarily stored in the activated carbon filter 33, so that the decomposition residue of the gaseous odor is adsorbed without leakage. Thereby, there exists an advantage which the deodorizing performance of the deodorizer 1 improves further.

  Moreover, in said structure, it is preferable that the heating means 34 has a substantially circular cross-sectional shape (refer FIG. 4). With such a configuration, the ventilation resistance when the heating means 34 is disposed on the catalyst filter 32 is small (a structure that is unlikely to hinder ventilation). Thereby, there exists an advantage which can heat the catalyst filter 32, maintaining the distribution | circulation of air appropriately.

  In the above configuration, it is preferable that the catalyst filter 32 is heated so that the temperature rise of the catalyst filter 32 is within 10 [° C.]. Thereby, there exists an advantage reduced to the extent that the temperature rise in the room by heating is negligible. In addition, when the catalyst filter 32 is heated by a larger temperature rise, it is preferable that the housing | casing 2 has a heat exchange structure.

[Thermo control deodorization]
In general, the odor of living space includes a high concentration odor that is temporarily generated and a low concentration odor that is continuously generated. Here, for a high-concentration odor, a method of deodorizing the odor by adsorbing the odor with a deodorizing filter (catalytic filter 32 and activated carbon filter 33) by blowing air with a large air volume is preferable. Thereby, since the concentration of odor is reduced to a predetermined level in a short time, it is possible to meet the need to quickly remove the strong odor that occurs temporarily.

  On the other hand, it is preferable to decompose the odor adsorbed by the catalyst filter 32 by blowing air with a small air volume. Thereby, decomposition | disassembly of an odor is performed efficiently. At this time, it is preferable that the catalyst filter 32 is heated to promote decomposition of odor. The heating of the catalyst filter 32 is performed by, for example, the heating means 34 described above.

  From the above viewpoint, in the deodorizer 1, it is preferable that the output of the blower 5 and the output of the heating means are set and changed according to the concentration of odor in the air (see FIGS. 11 and 12). Thereby, there exists an advantage by which a deodorizing process is performed efficiently according to the density | concentration of the odor in air. The odor concentration is detected by, for example, a gas sensor (not shown) installed in the suction port 21 of the housing 2.

  For example, when the concentration of odors in the air is larger than a predetermined threshold, the blower 5 is operated with a large air volume, and when the concentration of odors in the air is smaller than a predetermined threshold, the blower 5 is small. It is preferable to operate with an air volume (a smaller air volume than when operating with a large air volume). In such a configuration, the deodorizing process is performed mainly for odor adsorption during operation with a large air volume, and the deodorizing process is performed mainly for decomposition of the adsorbed odor during operation with a small air volume. Thereby, there exists an advantage which can perform the more suitable deodorizing process according to the density | concentration of the odor in air. In addition, it is preferable to prescribe | regulate suitably the air volume (large air volume and small air volume) of the air blower 5 according to the indoor space in which the deodorizer 1 is installed, and the specification of a deodorizer.

  In the above configuration, it is preferable that the catalyst filter 32 is heated by the heating means 34 when the air volume of the blower 5 is smaller than a predetermined threshold value (during operation with a small air volume). Thereby, since decomposition | disassembly of the odor adsorb | sucked by the catalyst filter 32 is accelerated | stimulated, there exists an advantage which the deodorizing performance of the deodorizer 1 improves effectively.

  FIG. 11 is a table showing the results of a performance test for the deodorizing process. In FIG. 11, the vertical axis represents the logarithmic concentration logC [ppm] of odor (formaldehyde) in the air, and the horizontal axis represents the operation time t [min] of the deodorizer 1. The solid line indicates the case where the catalyst filter 32 is heated by the heating means 34, the broken line indicates the case where the catalyst filter 32 is not heated, and the alternate long and short dash line indicates the catalyst filter 32. Is not installed (the adsorption deodorizing unit 3 has only the dust collection filter 31 and the activated carbon filter 33).

In this performance test, first, before the start of the operation of the deodorizer 1, the concentration of odor in the air is equal to or higher than _a predetermined threshold value na. For this reason, at the beginning of the operation, the blower 5 is driven with a large air volume, and the deodorizing process mainly performing odor adsorption is performed. Thereby, the concentration of odor is rapidly reduced to a certain value. At this time, the heating means 34 is turned off, and the catalyst filter 32 is not heated. Next, the concentration of the odor is performed switching to the small air volume from a large volume when they become less than a predetermined threshold value n _a, decomposition deodorization was main the odor adsorbed on the catalyst filter 32 is performed. Accordingly, there is an advantage that the odor component is decomposed and the adsorption force of the catalyst filter 32 is recovered. Further, at this time, the heating of the catalyst filter 32 is performed by the heating means 34, and the decomposition of the odor is promoted.

  As shown in the test results, it is understood that the air deodorization process is efficiently performed in a short time by switching the air volume of the blower 5 according to the odor concentration in the air. It can also be seen that the decomposition of the adsorbed odor is effectively promoted by heating the catalyst filter 32 when the air volume is small. Specifically, when the catalyst filter 32 is heated, the odor decomposition time is significantly shortened (about 50 [%]) compared to when the catalyst filter 32 is not heated. I understand.

[Ozone deodorization part]
Moreover, in this deodorizer 1, it is preferable that the inflow direction and the outflow direction of the air in the case 41 of the ozone deodorizing unit 4 are on different straight lines (see FIGS. 5 and 6). That is, the case 41 is configured such that the air inflow direction and the outflow direction are not in a straight line. In such a configuration, since the air that has flowed into the case 41 passes through the flow path bent from the inlet portion 411 toward the outlet portion 412, the air linearly passes through the case 41 (not shown). In comparison, the reaction between air and ozone is favorably performed. Thereby, since the deodorizing process in the ozone deodorizing part 4 is performed effectively, there exists an advantage which the deodorizing performance of the deodorizer 1 improves.

  For example, the ozone deodorizing unit 4 is configured such that the air flow direction (inflow direction) at the inlet 411 of the case 41 and the air flow direction (outflow direction) at the outlet 412 are substantially orthogonal (FIG. 6). reference). Specifically, the case 41 has a rectangular parallelepiped box shape, the inlet portion 411 is formed on the bottom surface of the case 41, and the outlet portion 412 is formed on the side surface of the case 41. Thereby, in the case 41, it is comprised so that the inflow direction and outflow direction of air may not be on a straight line. In addition, the exit part 412 is each formed with respect to the three side surfaces of the case 41 (refer FIG. 5).

[Body]
Moreover, in this deodorizer 1, the ozone deodorizing part 4 has the baffle 44 which stirs the air which flowed in in the case 41 (refer FIG. 5 and FIG. 6). The baffle 44 has, for example, a rib-like structure, and is disposed on the air flow path, which is the inlet 411 of the case 41. A plurality of baffles 44 are disposed on the downstream side of the inlet portion 411 of the case 41. In such a configuration, air collides with the baffle 44 on the downstream side of the inlet portion 411 of the case 41, and a turbulent flow is formed in the case 41 (near the ozone generating portion 42). Thereby, since reaction with the air and ozone in case 41 is accelerated | stimulated, there exists an advantage which the deodorizing performance of the deodorizer 1 improves. Further, since the baffle 44 has a simple structure, it can be reduced in size, and there is an advantage that a driving source such as a stirring fan (not shown) is unnecessary.

  Further, in the configuration in which the baffle body 44 has a rib-like structure, it is preferable that fins 441 are formed on the rib-like portion (see FIGS. 5 and 6). Such fins 441 efficiently form a turbulent flow in the case 41 and promote the reaction between air and ozone in the case 41. Thereby, there exists an advantage which the deodorizing performance of the deodorizer 1 improves further.

  Moreover, it is preferable that the fin 441 of the baffle body 44 is composed of, for example, a substantially arc-shaped protrusion or notch formed on the baffle body 44. In such a configuration, a three-dimensional vortex is generated in the case 41 by the air flowing into the case 41 hitting the fins 441 of the baffle body 44. Thereby, reaction of the air and ozone in case 41 is accelerated | stimulated, and there exists an advantage which the deodorizing performance of the deodorizer 1 improves further.

  Moreover, it is preferable to arrange | position the rectification | straightening part 413 which rectifies | straightens the flow of air in the upstream of the baffle 44 (refer FIG. 5 and FIG. 6). The rectifying unit 413 is configured by, for example, a filter having a honeycomb structure, and is disposed at the inlet 411 of the case 41 of the ozone deodorizing unit 4. In such a configuration, since the rectification unit 413 rectifies air on the upstream side of the baffle body 44, the air bias in the baffle body 44 is reduced. Thereby, the favorable eddy of air is formed in case 41, reaction of the air in case 41 and ozone is accelerated | stimulated, and there exists an advantage which the deodorizing performance of the deodorizer 1 improves further.

[Guide section]
Moreover, in this deodorizer 1, it is preferable to arrange | position the guide part 43 which guides the air in case 41 and generates a vortex | eddy_current in case 41 (refer FIG. 5 and FIG. 6). The guide portion 43 is made of, for example, a plate-like member that is curved or refracted in a U shape, a U shape, or a triangular cross section, and is directed toward the ozone generation portion 42 with respect to the ceiling portion of the case 41. Fixed installation. In such a configuration, the air in the case 41 is guided by the guide portion 43 and a vortex is generated in the case 41, so that the reaction between the air and ozone in the case 41 is promoted. Thereby, there exists an advantage which the deodorizing performance of the deodorizer 1 improves further.

  In the case where the ozone generating unit 42 is composed of an ultraviolet lamp, it is preferable that a photocatalyst is applied to the guide unit 43. Thereby, decomposition | disassembly of the odor in the air in case 41 is accelerated | stimulated. In particular, in the configuration in which the guide portion 43 is formed of a curved or refracted plate-like member, the orientation of the guide portion 43 can be adjusted so that the ultraviolet light from the ultraviolet lamp (ozone generating portion 42) hits the photocatalyst of the guide portion 43. . In such a configuration, as compared with the configuration in which the photocatalyst is applied to the flat ceiling portion of the case 41, the ultraviolet light of the ultraviolet lamp is efficiently irradiated to the photocatalyst of the guide portion 43. Thereby, since decomposition | disassembly of the odor in air is accelerated | stimulated, there exists an advantage by which the deodorizing process of air is performed efficiently. Further, since the guide portion 43 has a structure that is curved or refracted toward the ozone generation portion 42 side (inner side), leakage of ultraviolet rays to the outside of the case 41 is reduced.

[UV blocking structure]
Further, in this deodorizer 1, in the configuration in which the ozone generating part 42 is composed of an ultraviolet lamp, the ozone deodorizing part 4 has the ultraviolet blocking structures 413 and 414 for suppressing leakage of ultraviolet rays from the inside of the case 41, and the inlet part 411 of the case 41 and It is preferable to have in the exit part 412 (refer FIG.5, FIG.6, FIG.13 and FIG. 14). In the ultraviolet blocking structures 413 and 414, for example, an ultraviolet absorbing material having a honeycomb structure (or a corrugated structure) is arranged at the inlet portion 411 and the outlet portion 412 of the case 41, and the eyes of the honeycomb structure of the ultraviolet absorbing material are arranged. The ozone generation unit (ultraviolet lamp) 42 is configured to be inclined with respect to the irradiation direction of the ultraviolet rays. That is, a configuration is adopted in which the ultraviolet rays from the ozone generator 42 do not pass through the honeycomb structure of the ultraviolet absorbing material.

  In such a configuration, ultraviolet rays are blocked by the ultraviolet blocking structures 413 and 414, and leakage of ultraviolet rays from the ozone deodorizing unit 4 (case 41) is suppressed. Thereby, there exists an advantage by which the bad influence to the human body by ultraviolet rays or deterioration of the housing | casing 2 grade | etc., Is suppressed. In addition, in the configuration in which the ultraviolet blocking structures 413 and 414 have the honeycomb structure as described above, for example, air is less than in the configuration having a labyrinth structure (not shown) made of a metal plate or the like in which the ultraviolet blocking structure is bent. It is preferable in terms of easy passage. Thereby, there exists an advantage by which the distribution | circulation of the air in the ozone deodorizing part 4 is ensured.

  The positional relationship between the discharge port 22 of the housing 2 and the outlet portion 412 of the ozone deodorizing unit 4 is defined so that the outlet 412 of the ozone deodorizing unit 4 cannot be seen from the discharge port 22 of the housing 2. . Thereby, there exists an advantage by which the leakage of the ultraviolet-ray to the exterior of the housing | casing 2 is suppressed reliably.

[Securing the amount of ozone generated]
In general, in the ozone generation unit 42 composed of an ultraviolet lamp (for example, a mercury lamp), the amount of ozone generated is large at the initial stage, and the amount of ozone generated tends to decrease as the usage time increases. Therefore, in the deodorizer 1, it is preferable to adjust the driving time of the ozone generator 42 in order to ensure the amount of ozone generated (or the amount of ozone released). For example, when the cumulative number of flashes of the ultraviolet lamp that is the ozone generation unit 42 is equal to or less than a predetermined default value, the OFF time required for the flash cycle (ON / OFF duty ratio) of the ultraviolet lamp is set long, and the cumulative number of ultraviolet lamps is increased. When the number of blinks exceeds a predetermined value, it is preferable to set the blink cycle OFF time to be short. Thereby, since the lifetime of the ultraviolet lamp is extended, there is an advantage that the generation amount of ozone is stably ensured for a long period of time. In such a configuration, it is necessary to employ an ultraviolet lamp that can generate necessary and sufficient ozone even by blinking driving.

[Blower layout]
Moreover, in this deodorizer 1, while the air blower 5 is arrange | positioned in the downstream of the adsorption deodorizing part 3 and the upstream of the ozone deodorizing part 4, it is smaller than the air inlet (inlet in the adsorption deodorizing part 3 side). It is preferable to have an air outlet (exit on the ozone deodorizing unit 4 side). That is, the blower 5 is arranged with the large suction port directed toward the adsorption deodorization unit 3 and the small discharge port directed toward the ozone deodorization unit 4. The blower 5 includes, for example, a sirocco fan.

  In such a configuration, since the blower 5 sucks air from the side of the adsorption / deodorization unit 3 in a wide suction area, the adsorption / deodorization unit 3 can suck air in a wide range. Then, since the deodorizing filters 31 to 33 of the adsorption deodorizing unit 3 can be increased in size, indoor air can be efficiently sucked in and deodorized. Thereby, there exists an advantage which enables the efficient deodorizing process of air.

  Further, since the blower 5 discharges air to the ozone deodorization unit 4 side with a small discharge area, air can be supplied intensively around the ozone generation unit 42 of the ozone deodorization unit 4. Thereby, reaction with air and ozone is performed efficiently and there exists an advantage which deodorizing performance improves. Further, there is an advantage that the ozone generating unit 42 can be downsized or reduced in number.

[Selection of ozone emission setting]
Further, in the deodorizer 1, as described above, ozone in the air is adjusted to a low concentration at the outlet of the ozone deodorizing unit 4, and is discharged into the room together with air. At this time, it is preferable that the amount of ozone released is switched according to the air volume. For example, when the rotational speed (air volume) of the blower 5 is acquired at the time of operation of the deodorizer 1, and the rotational speed of the blower 5 exceeds a predetermined threshold (for example, a threshold for large air volume and small air volume), The lighting time (for example, lighting ON / OFF time ratio) of the ozone generator 42 is switched according to a predetermined setting pattern. The lighting time is automatically switched by the control unit 6.

  For example, when operating with a large air volume, the volume of air returned to the room is large, so that the lighting time of the ozone generator 42 is set to be longer (for example, continuous lighting) so that the amount of generated ozone is increased. Be controlled. Conversely, when operating with a small air volume, the amount of ozone released into the room is less than the standard value (for example, 0.1 [ppm] of the occupational health standard or 0.05 [ppm] of the IEC air cleaner standard). Therefore, the lighting time of the ozone generator 42 is set to be short (flashing lighting).

  Here, in this deodorizer 1, in a configuration in which the amount of ozone generated (lighting time of the ozone generator 42) is switched according to the air volume, a plurality of setting patterns for switching the amount of ozone generated can be selected. It is preferable (refer FIG. 15). For example, in the setting pattern A, the amount of ozone released (the amount of ozone released during each operation with a large air amount, a medium air amount, and a small air amount) is set higher than the setting pattern B. Conversely, the setting pattern C Then, the amount of ozone released is set lower than the setting pattern B. These setting patterns can be arbitrarily selected or changed by the user. In such a configuration, for example, the user can set the setting pattern according to the environment (temperature / humidity, size, etc.) of the room where the deodorizer 1 is installed, the individual difference with respect to the ozone odor (whether the ozone odor is worrisome), or the like. By switching, the amount of ozone released into the room can be adjusted arbitrarily. This has the advantage that a more comfortable air environment is provided. Note that the setting patterns A to C of the ozone release amount can be manually performed by the user.

[Regulation of ozone concentration released]
Moreover, in this deodorizer 1, it is preferable that the density | concentration of the ozone discharge | released from the discharge outlet 22 of the housing | casing 2 is controlled by 0.01 [ppm] or more and 0.02 [ppm] or less. That is, the concentration of the released ozone is regulated so as to be within a predetermined range. Thereby, there exists an advantage by which the density | concentration of the discharge | released ozone is adjusted appropriately (so that it may become low concentration ozone).

  Here, in the deodorizer 1, the released ozone is generated in the ozone deodorization unit 4. For this reason, the density | concentration of the discharge | released ozone is adjusted by drive control of the ozone generation part 42 of the ozone deodorizing part 4. FIG. For example, the output of the ozone generator 42 (ultraviolet lamp lighting time) is controlled in accordance with the air volume to adjust the ozone generation volume (for example, in the case of a small air volume, the ultraviolet lamp lighting time is shortened). Control is performed). In addition, an ozone decomposition catalyst 413 that decomposes ozone and restricts the passage of ozone is disposed at each outlet portion 412 of the ozone deodorization unit 4, and the ozone concentration that is released in consideration of the action of the ozone decomposition catalyst 413 is regulated. The

[louver]
Low-concentration ozone not only has a masking effect, but also stays in the room, so that it comes into contact with the odorous component that stains the walls of the room and decomposes the odorous component. Therefore, when the odor source is specified in the room, it is preferable that the low-concentration ozone is sprayed directly on the odor source. For this reason, in this deodorizer 1, the louver (flap) 23 is arrange | positioned at the discharge port 22 of air, and it is comprised so that the blowing direction (wind direction) of air can be changed. In such a configuration, by changing the direction of the louver 23, low-concentration ozone can be sprayed directly on the source of odor, so that there is an advantage that the deodorizing effect in the room can be efficiently enhanced.

  Here, in this deodorizer 1, it is preferable that the discharge port 22 of the housing | casing 2 consists of the variable opening part 221 which can adjust an opening degree, and the normal opening part 222 which has a fixed opening degree (FIG. 1). FIG. 16 and FIG. 16). The opening of the variable opening 221 can be changed depending on the posture of the louver 23, and can be fully closed (see FIG. 16C).

  In such a configuration, when the louver 23 is fully opened, air is mainly discharged from the variable opening 221 side (see FIG. 16A). Further, in a state where the louver 23 is half open, the louver 23 acts as a resistor, and air is discharged from both the variable opening 221 and the normal opening 222 (see FIG. 16B). Further, when the louver 23 is fully closed, air is discharged from the normal opening 222 (see FIG. 16C).

  With such a configuration, an air flow path is secured even when the louver 23 is fully closed, so that heat is trapped inside the housing 2 due to heat generation inside the housing 2 (for example, heat generation by the heating means 34). There are benefits to be prevented. In addition, since air is discharged from both the variable opening 221 and the normal opening 222 even when the louver 23 is opened, the louver 23 is compared with a configuration in which air is discharged from only the variable opening 221 (not shown). The wind speed when heading forward (the direction in which people are present) is reduced. Thereby, there is an advantage that discomfort when the wind directly hits a person is reduced.

  Moreover, in said structure, it is preferable that the housing | casing 2 has a convex part and the discharge port 22 is formed in this convex part (refer FIG. 1 and FIG. 2). In such a configuration, since the housing 2 has a convex portion (convex shape), the opening area of the discharge port 22 can be increased compared to a configuration in which the discharge port is formed in the flat portion (not shown). Accordingly, there is an advantage that noise during operation with a large air volume is reduced because of low pressure loss. Similarly, the housing 2 may have a concave portion and the discharge port 22 may be formed in the concave portion (not shown).

  Further, in the above configuration, the variable opening 221 is formed in the slope of the convex portion of the housing 2 on the slope of the housing 2 on the suction port 21 side, and the normal opening is provided on a slope on a side different from this slope. A portion 222 is preferably formed (see FIGS. 1 and 2). In such a configuration, it is possible to prevent the air discharged from the normal opening 222 from being sucked into the suction port 21 as a shortcut. Thereby, there exists an advantage by which the deodorized air is reduce | restored appropriately indoors.

  Moreover, in said structure, it is preferable that the variable opening part 222 has a structure which can adjust a wind direction (it can adjust the blowing direction of the air which blows off from the discharge outlet 22 of the housing | casing 2). For example, the variable opening 222 is configured by a louver. In such a configuration, there is an advantage that the direction in which ozone is blown from the discharge port (wind direction) can be changed by adjusting the wind direction at the opening that can adjust the wind direction. Further, in this configuration, by adjusting the air direction at the variable opening 222, the air flow that is about to be sucked into the housing 2 from inside the room is pushed back into the room on the air blown out from the housing 2. The situation is suppressed. Thereby, since the air circulation between the room and the deodorizer 1 is made efficient, there is an advantage that the deodorization performance of the deodorizer 1 is improved.

  As described above, the deodorizer according to the present invention is useful in that the deodorization performance can be improved by improving the efficiency of the ozone deodorization treatment.
