Contents of the invention

An object of the present invention is to provide a deodorizer capable of improving deodorization performance.

In order to achieve the above object, the deodorizer according to the present invention performs deodorization treatment of air, and is characterized in that it has a frame body having an air suction port and an air discharge port, and has an internal connection between the suction port and the discharge port. The air passage; the adsorption deodorization part is arranged on the aforementioned air passage, and absorbs the odor in the air to deodorize the air; the ozone deodorization part is arranged on the aforementioned air passage, and uses ozone to perform the deodorization treatment of the air; and a blower that circulates air in the air passage, and releases the air deodorized by the adsorption deodorization unit and the ozone deodorization unit together with ozone to the outside from the discharge port of the housing.

In this deodorizer, there are provided: an adsorption deodorization unit, which absorbs odor in the air to deodorize the air; and an ozone deodorization unit, which uses ozone to deodorize the air, and the adsorption deodorization unit and ozone The partially deodorized air is released from the outlet to the outside (for example, indoors) together with ozone (low concentration ozone). In this structure, after adsorbing high-concentration odor in the air by the adsorption deodorization unit (such as a catalyst filter and an activated carbon filter), and absorbing low-concentration odor in the air by the ozone deodorization unit, the deodorized air is sent to external release. Thereby, since the deodorization process of air can be performed suitably, there exists an advantage that the deodorization performance of a deodorizer improves. In addition, since the low-concentration ozone is released to the outside together with the deodorized air, the low-concentration ozone can be used to efficiently decompose and remove the odor attached to the installation space of the deodorizer (such as indoor walls or furniture, etc.) advantage.

Moreover, the deodorizer in this invention arrange|positions the said ozone deodorization part on the downstream side of the said adsorption deodorization part.

In this deodorizer, first, the high-concentration odor in the air is adsorbed and deodorized by the adsorption deodorization unit, and then the low-concentration odor in the air is deodorized by the ozone deodorization unit. Thereby, there is an advantage of realizing efficient deodorization treatment by stepwise removing high-concentration odors to low-concentration odors.

Moreover, in the deodorizer of this invention, the said adsorption deodorization part has a catalyst filter which adsorbs and decomposes the odor in air.

In this deodorizer, since the adsorbed odor (for example, gaseous odor) can be decomposed by the catalyst filter, accumulation of gaseous odor can be suppressed. Thereby, there is an advantage of extending the replacement life of the filter (adsorption deodorization unit). In addition, in this structure, since the odor can be decomposed while blowing air continuously, it is possible to deodorize the room more efficiently than the structure (not shown) that must stop the blowing at the time of ozone decomposition. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer. In particular, in this structure, it is possible to efficiently decompose odors such as odors adhering to indoor walls or body odors that continue to occur from time to time.

In addition, in the deodorizer of the present invention, a filter is arranged downstream of the catalyst filter, and temporarily stores decomposition residues of odor in the air that has passed through the catalyst filter.

In this deodorizer, since the decomposition residue of gaseous odor in the air that has passed through the catalyst filter is temporarily stored in the filter (such as an activated carbon filter) on the downstream side thereof, the gas can be adsorbed without leakage. odorous decomposition residue. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer.

Moreover, the deodorizer in this invention has the heating means which heats the said catalyst filter.

In this deodorizer, the catalyst filter can be heated by a heating unit during operation. Thereby, since the decomposition of the gaseous odor adsorbed by the catalyst filter can be accelerated, there is an advantage of improving the deodorizing performance of the deodorizer. In addition, in this structure, since the decomposition of the gaseous odor is promoted without stopping the air blowing, the odor continuously generated during the treatment can be efficiently decomposed. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer.

Moreover, in the deodorizer of this invention, the said heating means is arrange|positioned by detours on the said catalyst filter.

In this deodorizer, since the heating unit is arranged in a detour on the catalyst filter (upstream or downstream side of the catalyst filter), substantially the entire area of the catalyst filter can be heated with one or a small number of heating units. Thereby, the catalyst filter can be heated efficiently with a simple structure, and there exists an advantage that the deodorization performance of a deodorizer can be improved.

In addition, in the deodorizer according to the present invention, the output of the blower and the output of the heating means are set and changed according to the concentration of the odor in the air.

In this deodorizer, since the output of the blower and the output of the heating unit can be set and changed according to the concentration of the odor in the air, there is an advantage that deodorization can be performed efficiently according to the concentration of the odor in the air.

Moreover, the deodorizer in this invention has a photocatalyst and the ultraviolet lamp which irradiates ultraviolet-ray to this photocatalyst.

In this deodorizer, since the photocatalyst can be used to decompose the odor in the air, there is an advantage that the deodorization performance of the deodorizer 1 can be further improved.

In addition, in the deodorizer of the present invention, the aforementioned ozone deodorizing unit has: a housing that constitutes a reaction space between air and ozone; and an ozone generating unit that generates ozone in the housing, and the inflow direction of the air in the housing is and the outflow direction are on different straight lines.

In this deodorizer, the inflow direction and the outflow direction of the air in the housing of the ozone deodorizer are on different straight lines. That is, in the case, the inflow direction and the outflow direction of air are not aligned on a straight line. In this configuration, since the air flowing into the tank passes through the flow path in a curved manner from the inlet to the outlet, the reaction between air and ozone can be favorably performed compared to a configuration in which air passes straight through the tank. Thereby, since the deodorization process of an ozone deodorization part can be efficiently performed, there exists an advantage that the deodorization performance of a deodorizer improves.

In addition, the structure of the deodorizer in the present invention is to have an ozone generating part that generates ozone released from the discharge port of the aforementioned frame to the outside, and at the same time, the amount of ozone generated in the aforementioned ozone generating part can be switched according to the air volume. One and selectable setting modes related to the switching of the aforementioned ozone generation.

In this deodorizer, because the setting mode related to the switching of the amount of ozone generation can be switched arbitrarily, for example, the user can set the deodorizer according to the room environment (temperature and humidity or space, etc.), personal differences to ozone smell (whether to feel to ozone smell), etc., arbitrarily adjust the amount of ozone released in the room. Thereby, there is an advantage that a more comfortable air environment can be provided.

In addition, in the deodorizer of the present invention, the concentration of ozone released from the outlet of the housing is limited to 0.01 [ppm] or more and 0.02 [ppm] or less.

In this deodorizer, there is an advantage that the concentration of released ozone can be adjusted appropriately (for example, low concentration ozone).

In addition, in the deodorizer according to the present invention, the discharge port of the housing has a variable opening with an adjustable opening and a normal opening with a constant opening.

In this deodorizer, when the variable opening is fully opened, air is mainly discharged from the variable opening side. In addition, when the variable opening is in the half-open state, air is discharged from both the variable opening and the normal opening. In addition, when the variable opening is fully closed, air is discharged from the normal opening. According to this configuration, since the air flow path can be ensured even when the variable opening is fully closed, there is an advantage of preventing heat accumulation inside the housing due to heat generation inside the housing (for example, heat generated by a heating unit).

In addition, in the deodorizer of the present invention, the discharge port of the frame has an opening that can adjust the wind direction and a normal opening that has a constant opening.

In this deodorizer, there is an advantage that the blowing direction (wind direction) of ozone from the discharge port can be changed by adjusting the wind direction through the opening part where the wind direction can be adjusted.

The effect of the invention

In the deodorizer in the present invention, since it is provided with: an adsorption deodorization part, which absorbs the odor in the air to deodorize the air; The air deodorized by the ozone deodorization unit and the ozone deodorization unit is released from the outlet to the outside together with the ozone. Therefore, after the high-concentration odor in the air is adsorbed by the adsorption deodorization unit, and the low-concentration odor in the air is adsorbed by the ozone deodorization unit, The deodorized air is released to the outside. Thereby, since the deodorization process of air can be performed suitably, there exists an advantage that the deodorization performance of a deodorizer improves. In addition, since the low-concentration ozone is released to the outside together with the deodorized air, there is an advantage that the low-concentration ozone can efficiently decompose and remove the odor attached to the installation space of the deodorizer.

(deodorizer)

The deodorizer 1 is installed indoors and has the function of reducing indoor odors (odors diffused indoors, odors adhering to walls or furniture, body odors that occur from time to time, etc.) and reduce discomfort caused by odors. The deodorizer 1 is installed, for example, in living spaces of ordinary homes or nursing homes, toilets, garbage rooms, corridors, waiting rooms or wards of hospitals, treatment rooms of hospitals, pet hotels, waiting rooms or treatment rooms of animal hospitals, and the like. In addition, this deodorizer 1 may be mounted on an air conditioner, an air cleaner, etc. (illustration omitted), for example.

This deodorizer 1 has a housing 2, an adsorption deodorization unit (adsorption unit) 3, an ozone deodorization unit (ozonolysis unit) 4, a blower 5, and a control unit 6 (see FIGS. 1 and 2 ). The frame body 2 is made of a resin member and has a box shape that can be erected on the ground. The housing 2 has a suction port 21 on its side (a surface perpendicular to the ground in an installed state) and a discharge port 22 on its top. In addition, an air passage R from the suction port 21 to the discharge port 22 is formed inside the housing 2 . Moreover, the adsorption deodorization part 3, the ozone deodorization part 4, and the blower 5 are arrange|positioned in this air passage R.

The adsorption deodorization unit 3 has a function of adsorbing dust and gaseous odor in the air. This adsorption deodorization part 3 is provided in the vicinity of the suction port 21 of the housing 2 on the air passage R in the housing 2 . In addition, the term "dust in the air" means, for example, coarse dust or smoke (fine particles) in the air. The gaseous odors in the air refer to, for example, sulfur-based odors such as kitchen waste and feces, acetaldehyde-based odors such as sweat and building materials, fatty acid-based odors such as body odor, and excrement and urine odors. Ammonia odor, etc.

This adsorption deodorization unit 3 is constituted by, for example, a dust collection filter 31 , a catalyst filter 32 and an activated carbon filter 33 , and has a three-layer structure formed by laminating them (see FIGS. 2 to 4 ). In addition, these deodorization filters 31-33 are laminated|stacked in the order of the dust collection filter 31, the catalyst filter 32, and the activated carbon filter 33 from an upstream side.

The dust collection filter 31 has a pleated structure, and also has a function of capturing coarse dust and smoke (particles) in the air. The catalyst filter 32 has a function of adsorbing and decomposing gaseous odors in the air. The catalyst filter 32 is composed of, for example, a filter doped with zeolite having ammonia-adsorbing properties, a filter containing metal oxides having formaldehyde-decomposing properties, and the like. The activated carbon filter 33 has a function of temporarily storing the decomposition residue of gaseous odor in the air which has passed through the catalyst filter 32 . The activated carbon filter 33 is, for example, a filter of a honeycomb structure filled with activated carbon, activated carbon added with a chemical adsorption characteristic of aldehyde odor, activated carbon added with a chemical adsorption characteristic of basic odor such as ammonia, etc. constitute. In addition, to this activated carbon filter 33, a catalyst having a decomposing action of sulfur-based odor is added.

In addition, the adsorption deodorization unit 3 can be easily detached from the housing 2, and the deodorization filters 31 to 33 are configured to be separable from each other. Therefore, there is an advantage that it is easy to detach and clean the dust collection filter 31 . Moreover, the dust collection filter 31 is comprised by thermally fusing the core-sheath structure fiber which consists of polypropylene and polybutylene, for example, and has high washability. Therefore, there is an advantage that the replacement life of the dust collection filter 31 is long.

The ozone deodorizer 4 has a function of decomposing the odor in the air using ozone (see FIG. 5 and FIG. 6 ). The ozone deodorizing unit 4 is provided on the downstream side of the adsorption deodorizing unit 3 in the air passage R of the housing 2 (near the discharge port 22 of the housing 2 ). Moreover, the ozone deodorization part 4 is comprised including the housing|casing 41 and the ozone generation part 42. The casing 41 is a box-shaped component made of a material (such as a metal material) that cannot penetrate ultraviolet rays, and constitutes a reaction space between air and ozone. In addition, the housing 41 has an inlet portion 411 and an outlet portion 412 for air. The ozone generator 42 has a function of generating ozone in the casing 41, and is constituted by, for example, an ultraviolet lamp. The ozone generator 42 is arranged near the inlet 411 of the casing 41 .

In addition, a photocatalyst is arranged in the ozone deodorization unit 4 . Specifically, a photocatalyst (for example, titanium oxide) is coated on the inner wall surface of the case 41 or the like. When ultraviolet rays are irradiated on this photocatalyst, hydroxyl radicals are generated in the casing 41 . Since the oxidative decomposition ability of the hydroxyl radical is stronger than that of ozone, it is effective for the decomposition of ammonia odor which is not easily decomposed by ozone.

And, the ozone generation part 42 that is made of ultraviolet lamp is preferable because of the following aspects: (1) because it is not easy to be affected by indoor temperature, humidity or air pressure, etc., so the generation amount of ozone can be kept constant; (3) Harmful substances such as nitrogen oxides will not be produced; (4) Oxygen free radicals with strong oxidative decomposition power and sterilizing lines are produced, so it is very conducive to deodorization.

The blower 5 has a function of blowing air to flow air into the air passage. The air blower 5 is constituted by, for example, a multi-blade fan, and is disposed on the downstream side of the adsorption deodorization unit 3 and on the upstream side of the ozone deodorization unit 4 .

The control unit 6 performs drive control of the heating unit 34 of the adsorption deodorization unit 3 , drive control of the ozone generator 42 of the ozone deodorization unit 4 , drive control of the blower 5 , and other controls necessary for driving the deodorizer 1 , which will be described later.

(The role of the deodorizer)

In this deodorizer 1, when the blower 5 is driven during operation, indoor air is sucked in from the suction port 21 and passes through the adsorption deodorizer 3 (see FIGS. 2 , 4 and 7 ). In this adsorption deodorization part 3, the deodorization process of high-concentration odor is performed, and the strong odor in air is removed. Specifically, first, coarse dust, smoke odor, etc. in the air are captured by the suction filter 31 of the adsorption deodorization unit 3 . Then, gaseous odors in the air are adsorbed and decomposed by the catalyst filter 32 . Then, the decomposition residue of the gaseous odor in the air which has passed through the catalyst filter 32 is temporarily stored by the activated carbon filter 32 .

In addition, by providing the catalyst filter 32 and the activated carbon filter 33 with a honeycomb structure, gaseous odors in the air passing therethrough can be efficiently adsorbed. In addition, in the catalyst filter 32, since the gaseous odor adsorbed is decomposed, accumulation of odor components can be suppressed. Thereby, since the saturation of the odor component in the catalyst filter 32 is delayed, there is an advantage of extending the replacement life of the filter (adsorption deodorization unit 3 ).

Then, air is sent into the ozone deodorization part 4 via the blower 5 (refer FIG. 2, FIG. 6, and FIG. 7). In this ozone deodorization part 4, the deodorization process of the low-concentration odor in air is performed, and the trace amount of odor in the air which was not removed by the adsorption deodorization part 3 is removed. Specifically, in the casing 41 of the ozone deodorization unit 4, the ozone generated by the ozone generation unit 42 reacts with air to deodorize the air. Moreover, in the ozone deodorization part 4, when ultraviolet-ray is irradiated to the photocatalyst in the case 41, a hydroxyl radical will generate|occur|produce in a case. Then, the odor in the air is decomposed by the hydroxyl radicals to deodorize the air.

Then, the air that has passed through the ozone deodorization unit 4 is released into the room from the discharge port 22 of the housing 2 to be reduced. The air is deodorized by the adsorption deodorization unit 3 and the ozone deodorization unit 4, and is brought into a nearly odorless state.

Here, low concentrations of ozone are contained in the air that is returned to the room. This low-concentration ozone is mixed with air in the ozone deodorization unit 4, and released into the room together with the deodorized air. Utilizing this low concentration of ozone can decompose the peculiar smell attached to indoor walls, sofas, furniture, clothes, etc.

(Effect of deodorizer)

In this deodorizer 1, there are: an adsorption deodorization unit 3, which absorbs the odor in the air and deodorizes the air; and an ozone deodorization unit 4, which uses ozone to deodorize the air. And the air deodorized by the ozone deodorization unit 4 is released from the outlet 22 to the outside (for example, indoors) together with ozone (low-concentration ozone) (see FIG. 7 ). In this structure, after the high-concentration odor in the air is adsorbed by the adsorption deodorization part 3 (catalyst filter 32 and activated carbon filter 33), and the low-concentration odor in the air is adsorbed by the ozone deodorization part 4, after the deodorization treatment of air is released to the outside. Thereby, since air can be deodorized appropriately, there is an advantage of improving the deodorizing performance of the deodorizer 1 (see FIG. 8 ). In addition, since the low-concentration ozone is released to the outside together with the deodorized air, the low-concentration ozone can efficiently decompose and remove the odor attached to the installation space of the deodorizer 1 (for example, indoor walls or furniture, etc.). Advantages (see Figure 8). In addition, since the odor-masking effect can be obtained by utilizing the released low-concentration ozone, it has the advantage of giving the user a near-odorless feeling.

Moreover, in this deodorizer 1, the ozone deodorization part 4 is arrange|positioned on the downstream side of the adsorption deodorization part 3 (refer FIG.2 and FIG.7). In this structure, first, the adsorption deodorization unit 3 absorbs high-concentration odor in the air to perform deodorization, and then the ozone deodorization unit 4 deodorizes low-concentration odor in the air using ozone. Thereby, there is an advantage that efficient deodorization treatment can be realized by performing stepwise removal from high-concentration odor to low-concentration odor. For example, in a configuration in which deodorization of low-concentration odors is performed first, high-concentration odors cannot be sufficiently removed.

Moreover, in the deodorizer 1, the adsorption deodorization part 3 has the catalyst filter 32 which adsorbs and decomposes the gaseous odor in air (refer FIG.3 and FIG.4). In this configuration, since the adsorbed gaseous odor is decomposed by the catalyst filter 32, accumulation of the gaseous odor can be suppressed. Thereby, there is an advantage of extending the replacement life of the filter (adsorption deodorization unit 3). In addition, in this structure, since the odor can be decomposed while blowing continuously, it is possible to deodorize the room more efficiently than the structure (not shown) in which the blowing must be stopped when the odor is decomposed. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer 1 . In particular, in this structure, it is possible to efficiently decompose odors such as adhering to indoor walls and the like, or odors such as body odors that are continuously generated from time to time.

Moreover, in this deodorizer 1, the adsorption deodorization part 3 has the activated carbon filter 33 on the downstream side of the catalyst filter 32 (refer FIG. 3 and FIG. 4). In this structure, since the decomposition residue of the gaseous odor in the air passing through the catalyst filter 32 can be temporarily stored in the activated carbon filter 33, the decomposition residue of the gaseous odor can be adsorbed without leakage. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer 1 (see FIG. 8 and FIG. 9 ).

In addition, in this deodorizer 1, since the ozone deodorization unit 4 has a photocatalyst and an ultraviolet lamp (ozone generating unit 42) that irradiates ultraviolet rays to the photocatalyst, the photocatalyst can be used to decompose the odor in the air, so it has a further improvement. Advantages of the deodorizing performance of the deodorizer 1 (see FIG. 8 and FIG. 9 ).

(heating unit)

Moreover, in this deodorizer 1, it is preferable that the adsorption deodorization part 3 has the heating means 34 which heats the catalyst filter 32 (refer FIG. 2, FIG. 3). The heating unit 34 is constituted by, for example, a wire heater, an electric furnace, or the like, and is placed in direct contact with the catalyst filter 32 or in indirect contact therewith through an intermediate member (heat conduction member 342 ).

In this structure, the catalyst filter 32 is heated by the heating unit 34 when the deodorizer 1 is in operation. Thereby, since the decomposition of the gaseous odor adsorbed by the catalyst filter 32 can be accelerated, there is an advantage of improving the deodorizing performance of the deodorizer 1 . In addition, in this structure, since the decomposition of the gaseous odor is promoted without stopping the air blowing, the odor continuously generated during the treatment can be efficiently decomposed. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer 1 . In addition, since accumulation of gaseous odor in the catalyst filter 32 can be suppressed thereby, there is an advantage of extending the replacement life of the filter (adsorption deodorization unit 3 ).

In addition, in the above structure, it is preferable that the heating unit 34 has a bendable structure and is arranged in a detour on the catalyst filter 32 (upstream side or downstream side of the catalyst filter 32 ) (see FIG. 3 ). For example, the heating unit 34 is constituted by a wire heater, and is arranged in a serpentine shape over substantially the entire area of the catalyst filter 32 . In this configuration, substantially the entire area of the catalyst filter 32 can be heated by one or a small number of heating units (wire heaters) 34 . Thereby, the catalyst filter 32 can be heated efficiently by the simple heating means 34, and there exists an advantage that the deodorization performance of the deodorizer 1 improves.

In addition, in the above-mentioned structure, it is preferable to properly define the serpentine interval (interval between bellows arrangements) of the heating units 34 so as not to hinder ventilation.

In addition, the heating unit 34 is preferably arranged in close contact with the catalyst filter 32 (see FIG. 10 ). For example, a structure is preferable in which the heating unit 34 is held by a rigid heating frame 341 , and the heating unit 34 is directly or indirectly biased against the catalyst filter 32 by the heating frame 341 . The heating frame 341 has, for example, a plurality of claws (not shown), and the heating unit 34 is pressed against the catalyst filter 32 while being bent by these claws. In this configuration, since the degree of close contact between the heating unit 34 and the catalyst filter 32 is high, the catalyst filter 32 can be heated efficiently. Thereby, there is an advantage of improving the decomposition performance of gaseous odor by the catalyst filter 32 .

In addition, in this structure, it is preferable that a heat conduction member 342 having heat conduction characteristics is interposed between the heating unit 34 and the catalyst filter 32 (see FIG. 10 ). That is, the heating unit 34 is placed in close contact with the catalyst filter 32 via the heat conduction member 342 . The heat conduction member 342 is made of, for example, a mesh material made of metal or polypropylene. In this structure, efficient heat conduction from the wire heater 34 to the catalyst filter 32 can be achieved via the heat conduction member 342 . Thereby, since the heating of the catalyst filter 32 can be efficiently performed, there exists an advantage that the gaseous odor decomposition performance by the catalyst 32 improves. In addition, since the direct frictional contact between the heating unit 34 and the catalyst filter 32 can be suppressed by the presence of the heat conduction member 342 , there is an advantage that disconnection of the heating wire heater 34 can be effectively suppressed.

In addition, in the above structure, in the structure (not shown) in which the heating unit 34 is constituted by an electric furnace, the heating unit 34 may be in direct contact with the contact catalyst filter 32 without interposing the heat conduction member 342. configuration. Thereby, since more efficient heat transfer can be performed, there is an advantage that the decomposition action of the catalyst filter 32 is more activated.

In addition, in the above configuration, it is preferable to arrange the heating unit 34 on the upstream side of the catalyst filter 32 (see FIGS. 4 and 10 ). Thereby, since the heat of the heating unit 34 can be efficiently transferred to the catalyst filter 32 (and further to the activated carbon filter 33 ), there is an advantage of improving the odor decomposition function by the catalyst filter 32 .

In addition, in the above structure, it is preferable that the activated carbon 33 is disposed close to the downstream side of the catalyst filter 32 (see FIGS. 2 to 4 ). In this structure, since the heat of the heating unit 34 is transferred to the activated carbon filter 33 via the catalyst filter 34, the activated carbon filter 33 is also heated together with the catalyst filter 32. Thereby, there is an advantage that the regeneration of the activated carbon filter 33 can be performed. In addition, in this structure, since the decomposition residue of the gaseous odor in the air passing through the catalyst filter 32 is temporarily stored in the activated carbon filter 33, the gaseous odor decomposition residue is adsorbed without leakage. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer 1 .

In addition, in the above structure, it is preferable that the heating unit 34 has a substantially circular cross-sectional shape (see FIG. 4 ). In this structure, when the heating unit 34 is disposed on the catalyst filter 32, the ventilation resistance is small (a structure that hardly hinders ventilation). Thereby, there is an advantage that the catalyst filter 32 can be heated while appropriately maintaining air circulation.

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

(thermal control deodorization)

In general, the odor in the living space includes temporarily generated high-concentration odor and continuously generated low-concentration odor. Here, for high-concentration odor, it is preferable to perform deodorization treatment by blowing with a large air volume and adsorbing the odor with the deodorization filter (catalyst filter 32 and activated carbon filter 33 ). As a result, since the concentration of the odor can be reduced to a predetermined level in a short time, it is possible to quickly remove a strong odor that is temporarily generated.

On the other hand, it is preferable to decompose the odor adsorbed by the catalyst filter 32 by blowing with a small air volume. Thereby, odor decomposition can be efficiently performed. In addition, at this time, it is preferable to heat the catalyst filter 32 to accelerate the decomposition of the odor. The catalyst filter 32 is heated, for example, by the heating unit 34 described above.

From the above-mentioned viewpoints, in this deodorizer 1, it is preferable to change the output of the blower 5 and the output of the heating means according to the odor concentration in the air (see FIG. 11 and FIG. 12 ). Thereby, there is an advantage that the deodorization process can be efficiently performed according to the concentration of the odor in the air. In addition, the concentration of the odor can be detected by a gas sensor (not shown) provided at the suction port 21 of the casing 2 .

For example, preferably when the odor concentration in the air is greater than a predetermined threshold, the air blower 5 is operated with a large air volume, and when the odor concentration in the air is less than a predetermined threshold, the air blower 5 is operated with a small air volume (less than a large air volume). Air volume during air volume operation) operation. In this configuration, the deodorization process is mainly performed on the adsorption of odor during operation at a large air volume, and the deodorization process is mainly performed on the decomposition of the adsorbed odor during operation at a low air volume. Thereby, there is an advantage that an appropriate deodorization process can be performed according to the concentration of the odor in the air. In addition, the air volume (large air volume and small air volume) of the blower 5 is preferably determined appropriately according to the space in the room where the deodorizer 1 is installed or the specifications of the deodorizer.

In addition, in the above configuration, when the air volume of the blower 5 is lower than a predetermined threshold value (when operating at a small air volume), it is preferable to heat the catalyst filter 32 by the heating unit 34 . Thereby, since the decomposition of the odor adsorbed by the catalyst filter 32 can be accelerated, there is an effect of efficiently improving the deodorizing performance of the deodorizer 1 .

Fig. 11 is a table showing the results of performance tests related to the above deodorization treatment. In FIG. 11 , the vertical axis represents the logarithmic concentration logC [ppm] of odor (formaldehyde) in the air, and the horizontal axis represents the operating time t [minute] of the deodorizer 1 . In addition, the solid line represents the case where the catalyst filter 32 is heated by the heating unit 34, the dotted line represents the case where the catalyst filter 32 is not heated, and the dotted line represents that the catalyst filter 32 is not provided (the adsorption deodorization unit 3 has only the adsorption and deodorization unit 32). dust filter 32 and activated carbon filter 33).

In this performance test, before the operation of the deodorizer 1 starts, the odor concentration in the air is greater than or equal to the predetermined threshold value na. Therefore, at the initial stage of operation, the blower 5 is driven at a large air volume to perform deodorization treatment mainly by odor adsorption. As a result, the odor concentration is rapidly reduced to a certain value. At this time, the heating unit 34 is turned off, and the catalyst filter 32 is not heated. Then, when the odor concentration becomes less than or equal to the predetermined threshold value na, the air volume is switched from a large air volume to a small air volume, and deodorization processing is performed mainly to decompose the odor adsorbed by the adsorption catalyst 32 . Thereby, there is an advantage that the odor component is decomposed and the adsorption force of the catalyst filter 32 is restored. In addition, at this time, the catalyst filter 32 is heated by the heating unit 34 to promote the decomposition of the odor.

As shown by the test results, it was found that by switching the air volume of the blower 5 according to the concentration of the odor in the air, it is possible to efficiently deodorize the air in a short time. In addition, it can be seen that the decomposition of the adsorbed odor can be efficiently promoted by heating the catalyst filter 32 at a small air volume. Specifically, when the catalyst filter 32 is heated, it can be seen that the decomposition time of the odor is significantly (about 50 [%]) shorter than when the heating is not performed.

(Ozone Deodorization Division)

In addition, in this deodorizer 1, it is preferable that the air inflow direction and the outflow direction in the casing 41 of the ozone deodorizer 4 be on different straight lines (see FIG. 5 and FIG. 6 ). That is, it is configured such that the inflow direction and the outflow direction of air are not aligned on a straight line in the casing 41 . In this configuration, for example, the air flowing into the housing 41 is bent and passed from the inlet portion 411 to the outlet portion 412 , so it can be better than the configuration (not shown) in which the air passes straight through the housing 41 . To carry out the reaction of air and ozone. Thereby, since the deodorization process of the ozone deodorization part 4 can be efficiently performed, there exists an advantage that the deodorization performance of the deodorizer 1 improves.

For example, in the ozone deodorization unit 4, the flow direction (inflow direction) of the air at the inlet portion 411 of the casing 41 is configured to be substantially perpendicular to the flow direction (outflow direction) of the air at the outlet portion 412 ( Refer to Figure 6). Specifically, the housing 41 has a rectangular parallelepiped box shape, while the inlet portion 411 is formed on the bottom surface of the housing 41 and the outlet portion 412 is formed on the side surface of the housing 41 . Therefore, it is configured such that the inflow direction and the outflow direction of air are not on a straight line in the housing 41 . In addition, outlet portions 412 are formed on three side surfaces of the housing 41 (see FIG. 5 ).

(spoiler)

Moreover, in this deodorizer 1, the ozone deodorization part 4 has the disturbance body 44 which agitates the air which flows into the casing 41 (refer FIG. 5 and FIG. 6). The turbulent body 44 has, for example, a rib-like structure, and is arranged on the air flow path of the inlet portion 411 of the casing 41 . In addition, a plurality of turbulent bodies 44 are arranged on the downstream side of the inlet portion 411 of the casing 41 . In this configuration, the air collides with the turbulent body 44 on the downstream side of the inlet portion 411 of the housing 41 to form a turbulent flow in the housing 41 (near the ozone generating unit 42 ). Thereby, since the reaction of the air and ozone in the casing 41 can be accelerated, there is an advantage of improving the deodorizing performance of the deodorizer 1 . In addition, since the turbulent body 44 has a simple structure, it can be downsized, and there is an advantage that it does not require a driving source such as a stirring fan (not shown).

In addition, when the turbulent body 44 has a rib-like structure, it is preferable to form fins 441 on the rib-like portion (see FIGS. 5 and 6 ). The fins 441 efficiently form turbulent flow in the housing 41 to promote the reaction between the air in the housing 41 and ozone. Thereby, there is an advantage of further improving the deodorizing performance of the deodorizer 1 .

In addition, the fins 441 of the turbulent body 44 are preferably constituted by, for example, substantially arc-shaped protrusions or notches formed on the turbulent body 44 . In this structure, the air flowing into the casing 41 collides with the fins 441 of the turbulent body 44 to generate a three-dimensional vortex in the casing 41 . Thereby, the reaction of the air and ozone in the casing 41 can be accelerated, and there is an advantage that the deodorizing performance of the deodorizer 1 can be further improved.

In addition, it is preferable to arrange the rectification part 413 which rectifies the air flow on the upstream side of the turbulent body 44 (refer FIG. 5 and FIG. 6). The rectification part 413 is comprised by the filter which has a honeycomb structure, for example, and is arrange|positioned at the inlet part 411 of the casing 41 of the ozone deodorization part 4. In this structure, since the rectifying portion 413 rectifies the air near the upstream side of the turbulent body 44 , it is possible to reduce air deflection on the turbulent body 44 . Thus, a good air vortex can be formed in the housing 41 to promote the reaction of the air and ozone in the housing 41, which has the advantage of further improving the deodorization performance of the deodorizer 1.

(guide department)

Moreover, in this deodorizer 1, it is preferable to arrange the guide part 43 which guides the air in the housing 41 and generates a vortex in the housing 41 (refer FIG. 5 and FIG. 6). The guide part 43 is formed of a plate-shaped member that is bent or bent into a U-shape, a U-shape, or a triangular cross-section. In this structure, since the air in the casing 41 is guided by the guide part 43 and a vortex is generated in the casing 41, the reaction between the air in the casing 41 and ozone is accelerated. Thereby, there is an advantage of further improving the deodorizing function of the deodorizer 1 .

Furthermore, in the structure in which the ozone generation part 42 is comprised by the ultraviolet lamp, it is preferable to apply|coat a photocatalyst to the said guide part 43. As shown in FIG. Thereby, the decomposition of the odor in the air in the casing 41 can be promoted. In particular, in a structure in which the guide part 43 is formed of a curved or bent plate member, the direction of the guide part 43 can be adjusted so that the ultraviolet rays of the ultraviolet lamp (ozone generating part 42 ) face the photocatalyst of the guide part 43 . In this structure, compared with the structure in which the photocatalyst is coated on the flat top of the case 41, the photocatalyst of the guide part 43 can be efficiently irradiated with the ultraviolet rays of the ultraviolet lamp. Thereby, since decomposition|disassembly of the odor in air can be accelerated|stimulated, there exists an advantage that an air deodorization process can be performed efficiently. In addition, the leakage of ultraviolet rays to the outside of the casing 41 can be reduced by making the guide part 43 have a structure bent or bent toward the ozone generating part 42 side (inside).

(ultraviolet blocking structure)

In addition, in this deodorizer 1, in the structure in which the ozone generating part 42 is composed of an ultraviolet lamp, it is preferable that the ozone deodorizing part 4 has ultraviolet blocking structures 413, 414 at the inlet part 411 and the outlet part 421 of the housing 41, which suppress Leakage of ultraviolet rays from inside the casing 41 (see FIGS. 5 , 6 , 13 and 14 ). The ultraviolet blocking structures 413, 414 are configured, for example, by disposing an ultraviolet absorbing material having a honeycomb structure (or a corrugated structure) at the entrance 411 and the exit 412 of the casing 41, and making the holes of the honeycomb structure of the ultraviolet absorbing material, It is inclined with respect to the direction in which ultraviolet rays are irradiated from the ozone generator (ultraviolet lamp) 42 . That is, a structure is adopted in which ultraviolet rays from the ozone generating unit 42 do not pass through the pores of the honeycomb structure of the ultraviolet absorbing material.

In this structure, ultraviolet rays are blocked by the ultraviolet blocking structures 413 and 414 to suppress the leakage of ultraviolet rays from the ozone deodorizing unit 4 (casing 41 ). Thereby, there is an advantage of suppressing adverse effects on the human body and deterioration of the housing 2 and the like due to ultraviolet rays. In addition, in the structure in which the ultraviolet blocking structures 413 and 414 have the above-mentioned honeycomb structure, compared with, for example, the structure (not shown) in which the ultraviolet blocking structure has a labyrinth structure composed of bent metal plates, it is easier for air to pass through. aspects are preferred. Thereby, there is an advantage that air circulation in the ozone deodorization unit 4 is ensured.

In addition, the positional relationship between the outlet 22 of the housing 2 and the outlet 412 of the ozone deodorizer 4 is limited so that the outlet 412 of the ozone deodorizer 4 cannot be seen from the outlet 22 of the housing 2 . Thereby, there is an advantage that leakage of ultraviolet rays to the outside of the housing 2 can be reliably suppressed.

(Securing of Ozone Generation Quantity)

Generally, in the ozone generating unit 42 composed of an ultraviolet lamp (for example, a mercury lamp) or the like, the amount of ozone generated tends to be large at the initial stage, but tends to decrease as the usage time increases. Therefore, in this deodorizer 1 , in order to ensure the amount of ozone generated (or the amount of released ozone), it is preferable to adjust the driving time of the ozone generating unit 42 . For example, when the cumulative number of flickers of the ultraviolet lamp as the ozone generating unit 42 is less than or equal to a predetermined predetermined value, the off time in the flicker cycle (on/off duty ratio) of the ultraviolet lamp is preferably set longer. , and when the cumulative number of flickers of the ultraviolet lamp exceeds a predetermined predetermined value, the off time of the flicker cycle is set to be shorter. Accordingly, since the life of the ultraviolet lamp is extended, there is an advantage that the amount of ozone generation can be stably ensured for a long period of time. In addition, in this configuration, it is necessary to employ an ultraviolet lamp capable of generating sufficient ozone even by flickering drive.

(Blower configuration)

In addition, in this deodorizer 1, it is preferable that the blower 5 is arranged on the downstream side of the adsorption deodorization part 3 and the upstream side of the deodorization part 4, and has an air discharge port smaller than the air suction port (the inlet on the side of the adsorption deodorization part 3). (The outlet located on the side of the ozone deodorization unit 4). That is, the blower 5 is arranged so that the larger suction port faces the adsorption deodorization part 3 side, and the smaller discharge port faces the ozone deodorization part 4 side. In addition, the air blower 5 is provided with, for example, a multi-blade fan.

In this structure, since the air blower 5 takes in air from the side of the suction deodorizing part 3 by utilizing a large suction area, it is possible to suck air in a wide range by the adsorption deodorizing part 3 . Then, since the deodorization filters 31 to 33 of the adsorption deodorization unit 3 can be increased in size, it is possible to efficiently suck in room air and perform deodorization treatment. Thereby, there is an advantage that efficient deodorization of air can be performed.

In addition, since the air blower 5 discharges air toward the ozone deodorization unit 4 side with a narrow discharge area, it is possible to intensively supply air around the ozone generation unit 42 of the ozone deodorization unit 4 . Thereby, the reaction between air and ozone can be efficiently advanced, and there is an advantage of improving deodorization performance. In addition, there is an advantage in that the ozone generating unit 42 can be downsized or reduced in number.

(Setting selection of ozone emission amount)

Moreover, in this deodorizer 1, as mentioned above, the ozone in the air is adjusted to a low concentration at the outlet of the ozone deodorization part 4, and it discharge|releases into a room together with air. At this time, it is preferable that the emission amount of ozone can be switched according to the air volume. For example, when the deodorizer 1 is working, the rotational speed (air volume) of the blower 5 is obtained, and when the rotational speed of the air blower 5 exceeds a predetermined threshold (for example, a threshold related to a large air volume and a small air volume), according to a prescribed setting mode, The lighting time of the ozone generator 42 (for example, the on/off time ratio of lighting) is switched. In addition, switching of the lighting time is automatically performed by the control unit 6 .

For example, when operating with a large air volume, since the volume of air returned to the room is large, the lighting time of the ozone generator 42 is set to be long (for example, continuous lighting), and the amount of ozone generated is controlled to increase. Conversely, when running with a small air volume, the lighting time of the ozone generating part 42 is set shorter (flickering lighting), so that the amount of ozone released into the room is lower than the standard value (for example, 0.1 [ppm] of the labor hygiene standard ] or 0.05 [ppm] of the IEC air cleaner specification, etc.).

Here, in the deodorizer 1, it is preferable to arrange a plurality of selectable setting modes related to the switching of the ozone generation amount in the structure in which the amount of ozone generation (the lighting time of the ozone generation unit 42) is switched according to the air volume. (Refer to Figure 15). For example, in setting mode A, set the release amount of ozone (the release amount of ozone during various operations under high air volume, medium air volume and small air volume) to be higher than that in setting mode B; In mode C, the amount of ozone emission is set lower than setting mode B. In addition, these setting modes are provided so that they can be arbitrarily selected or changed by the user. In this structure, for example, according to the environment of the room where the deodorizer 1 is installed (temperature and humidity or space, etc.), personal differences in ozone odor (whether you feel the odor of ozone), etc., the user can switch the setting mode and adjust the ozone to the room arbitrarily. release amount. Thereby, there is an advantage that a more comfortable air environment can be provided. In addition, the user can manually switch between the setting modes A to C of the ozone emission amount.

(limitation of released ozone concentration)

Moreover, in this deodorizer 1, it is preferable to limit the concentration of the ozone released from the discharge port 22 of the housing 2 to 0.01 [ppm] or more and 0.02 [ppm] or less. That is, the limit is such that the concentration of ozone released is within the specified range. Thereby, there is an advantage that the concentration of released ozone can be adjusted appropriately (low concentration ozone).

Here, in this deodorizer 1 , the released ozone is generated by the ozone deodorizer 4 . Therefore, the concentration of released ozone can be adjusted by driving control of the ozone generating part 42 of the ozone deodorizing part 4 . For example, the output of the ozone generator 42 (lighting time of the ultraviolet lamp) is controlled according to the air volume to adjust the amount of ozone generated (for example, when the air volume is small, control is performed to shorten the lighting time of the ultraviolet lamp). In addition, an ozonolysis catalyst 413 that decomposes ozone and restricts the passage of ozone is arranged at each outlet 412 of the ozone deodorization unit 4 , and the concentration of released ozone is restricted by the function of the ozonolysis catalyst 413 .

(blinds)

Low-concentration ozone not only has the effect of masking odors, but also decomposes odor components by staying indoors and coming into contact with odor components attached to indoor walls, etc. Therefore, when it is determined that there is an odor source indoors, it is preferable to blow low-concentration ozone directly to the odor source. Therefore, in this deodorizer 1, the louver (damper) 23 is arrange|positioned at the air outlet 22, and it is comprised so that the blowing direction (wind direction) of air can be changed. In this structure, since the low-concentration ozone can be blown directly to the odor source by changing the direction of the louver 23, it has the advantage of efficiently improving the indoor deodorizing effect.

Here, in the deodorizer 1, it is preferable that the discharge port 22 of the frame body 2 is composed of a variable opening 221 whose opening can be adjusted and a normal opening 222 with a constant opening (refer to FIGS. Figure 16). The variable opening portion 221 can change the opening degree according to the posture of the above-mentioned louver 23, and can also be in a fully closed state (see FIG. 16(c)).

In this configuration, when the louver 23 is fully opened, air is mainly discharged from the variable opening portion 221 side (see FIG. 16( a )). In addition, when the louver 23 is in the half-open state, the louver 23 acts as a barrier, and air is discharged from both the variable opening 221 and the normal opening 222 (see FIG. 16( b )). In addition, when the louver 23 is fully closed, air is exhausted from the normal opening 222 (see FIG. 16( c )).

According to this structure, since the air circulation path can be ensured even when the louvers 23 are fully closed, it is possible to prevent heat from accumulating inside the housing 2 due to heat generated inside the housing 2 (for example, heat generated by the heating unit 34). The advantages. In addition, when the louver 23 is opened, air can also be exhausted from both the variable opening 221 and the normal opening 222 at the same time. It is possible to reduce the wind speed when the louver 23 is directed forward (in the direction of people). Thereby, there is an advantage of reducing discomfort when the wind blows directly on a person.

In addition, in the above structure, it is preferable that the housing 2 has a convex portion, and the discharge port 22 is formed on the convex portion (see FIGS. 1 and 2 ). In this structure, since the frame body 2 has a convex portion (convex shape), the opening area of the discharge port 22 is wider than that of a structure (not shown) in which the discharge port is formed on a flat portion. Thereby, because of the low pressure loss, there is an advantage that the noise at the time of operation with a large air volume can be reduced. Moreover, similarly, the housing 2 may have a concave portion, and a discharge port (not shown) may be formed in the concave portion.

In addition, in the above-mentioned structure, it is preferable to form the variable opening 221 on the slope of the convex portion of the frame 2, the slope on the side of the suction port 21 of the frame 2, and form the normal opening on the slope different from the slope. part 222 (see FIG. 1 and FIG. 2 ). In this structure, it is possible to prevent a situation where the air released from the normal opening 222 is immediately sucked in by the suction port. Thereby, there is an advantage that the deodorized air can be properly returned to the room.

In addition, in the above structure, it is preferable that the variable opening portion 222 has a structure capable of adjusting the wind direction (the blowing direction of the air blown out from the outlet 22 of the housing 2 can be adjusted). For example, the variable opening portion 222 is formed of a louver. In this structure, there is an advantage that the blowing direction (wind direction) of ozone from the discharge port can be changed by adjusting the wind direction through the opening that can adjust the wind direction. In addition, in this structure, by adjusting the airflow direction by the variable opening 222, it is possible to suppress the situation where the airflow drawn into the housing 2 from the room is expected to be pushed back into the room along with the air blown out from the housing 2. Thereby, since air circulation between the room and the deodorizer 1 can be efficiently performed, there is an advantage of improving the deodorizing performance of the deodorizer 1 .
