Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizer composition, more specifically, to a deodorizer composition having a strong deodorizing power which can be widely utilized to eliminate objectionable odors in the home and mitigate objectionable industrial odors generated by factories and the like. 2. Description of the Related Art The increasing urbantization of formerly sparsely-populated areas has brought more people into daily contact with the various smells and odors of their environment, and this has led to a strong interest in, and severe criticism of, particularly offensive odors. Various methods of treating offensive odors are known in the art, of which the following are typical: (1) Sensitive Deodorizing ... masking with perfumes or flavors; (2) Physical Deodorizing ... adsorption with, for example, activated carbon or absorption or clathrating with, for example, cyclodextrin; (3) Chemical Deodorizing ... neutralization with an acid or alkali, oxidation or reduction with an oxidizing agent or reducing agent, or an addition of, for example, lauryl methacrate; and (4) Biological Deodorizing ... deodorizing by germicidal action with germicide, or effects obtained with microorganisms or enzymes. The sensitive deodorizing method is often unsuccessful since only the flavor of the odor is changed and the offensive odor itself is still present although masked, and thus if the balance between the offensive odor and the flavor is lost, the offensive odor again prevails and the balance must be restored. In the physical deodorizing method, although the offensive odor is absorped or clathrated, problems arise in that the adsorption power or clathrating power is not strong enough for practical use. In the chemical deodorizing method, certain chemicals should not be used from the viewpoint of safety, and although a chemical deodorization of one offensive odor can be achieved, this same process will have no affect on the other various offensive odors generated in daily life. In the biological deodorizing method, disadvantages in the deodorizing rate and a continuous effect or durability arise and, therefore, universal effects cannot be obtained by a single deodorizing method. Conventionally activated carbon is most widely used, and is known as a deodorizer capable of adsorbing various offensive odor components. Nevertheless, among such offensive odor components, the capability of activated carbon for the adsorption of lower amines is small, and in particular, the deodorizing power thereof against hydrogen sulfide and ammonia is low. Various attempts have been made to solve the above-mentioned problems. For example, JP-A-55-51421 (i.e., Japanese Unexamined Patent Publication) proposes that halides be supported on activated carbon; JP-A-53-137089 proposes that metals be supported on activated carbon; and the adhesion or deposition of acids or alkalis has been studied. Nevertheless, these proposals are not still satisfactory. Furthermore, although the above-mentioned patent publications generally describe deodorizing performances against various objectionable or offensive odors, the deodorizing speed (or rate) and the deodorizing amounts are also important factors, taking into consideration the utility of the deodorizer compositions. The present inventors have proposed, in JP-A-63-220874, the use of aluminosilicates having a specified Si0₂, MO n/2 and Al₂0₃ composition in terms of the oxides expressed by the three component composition as a deodorizer. SUMMARY OF THE INVENTION Accordingly, the objects of the present invention are to eliminate the above-mentioned disadvantages of the prior art and to provide a deodorizer composition exhibiting excellent deodorizing effects for various objectionable odors, and having a high deodorizing speed and safety. Another object of the present invention is to provide a deodorizer composition exhibiting an excellent deodorizing effect for various objectionable odors, and an excellent persistency of the effect. Other objects and advantages of the present invention will be apparent from the following description. In accordance with the present invention, there is provided a deodorizer composition comprising: (a) an aluminosilicate having the following composition, in terms of oxides, represented by the composition ratio of the three components: Si0₂ : 5 to 80 mole%; M0 n/2 : 5 to 65 mole%; Al₂0₃ : 1 to 60 mole%; wherein M represents at least one metal selected from the group consisting of zinc, copper, silver, cobalt, nickel, iron, titanium, barium, tin and zirconium, and n represented a valence of metal; and (b) at least one component selected from the group consisting of (i) at least one oxidizing agent selected from the group consisting of organic peracids and salts thereof and persulfate, (ii) at least one plant extract selected from the group consisting of Rosemary extracts and Sage extracts, and (iii) at least one germicide selected from the group consisting of p-chloro-m-xylenol, butyl-m-cresol, o-phenylphenol, and α-bromocinnamic aldehyde. DESCRIPTION OF THE PREFERED EMBODIMENT The activated charcoal, silica gel, clay mineral, and aluminosylycate usable as the component (a) in the present invention preferably has a BET specific area of 100 m²/g or more, more preferably 500 to 2000 m²/g, when determined with N₂ gas. Activated charcoal may be obtained by a treatment of, for example, coal, petroleum residue, charcoal, fruit, and shells, by the gas activation method using, for example, steam, carbon dioxide, or the chemical activation method using, for example, zinc chloride. As the aluminosilicate, zeolite and those having the composition ratio of the three components represented in terms of oxides shown below are preferable: SiO₂: 5 to 80 mole%, preferably 25 to 75 mole%; Mo n/2 : 5 to 65 mole%, preferably 15 to 60 mole%; Al₂O₃: 1 to 60 mole%, preferably 1 to 45 mole% wherein M represents at least one metal selected from zinc, copper, silver, cobalt, nickel, iron, titanium, barium, tin and zirconium, and n represents a valence of metal. Of the component (a), aluminosilicates, in particular are considered to have the characteristics of a solid acid and solid acid group, and it has been reported that the acidity varies depending on the content of alumina in silica-alumina type catalysts, and that the acidity differs depending on the ratio of the contents of alumina and silica (Kozo Okabe: Acidic and Basic Catalysts, p. 183 (1967)). Further, since the aluminosilicate has a structure in which acidic SiO₂ and basic metal oxides are bound together, it has basic and acidic polarities and may be considered to exhibit deodorizing effect for objectionable odor components based primarily on a chemical adsorption and a chemical reaction. The aluminosilicate is obtained as a white or pale-colored powder, and is prepared by allowing a water soluble silicate, a water-soluble metal salt, and further, a water-soluble salt aluminum salt and/or a water-soluble aluminate, in amounts corresponding to the above-mentioned composition ratio, to react in the presence of water, and if necessary, heating the precipitates obtained in the presence of water. The above-mentioned reaction proceeds steadily due to a metathetical reaction. Namely, when an alkali silicate such as sodium silicate is used as a silica component, a water-soluble metal salt such as a chloride, nitrate, and sulfate is used as a metal oxide component, and further, sodium aluminate and/or a water-soluble aluminum salt such as aluminum chloride or aluminum sulfate are used as the alumina component, these components are mixed together in the presence of water, followed by effecting the metathetical reaction. To uniformly effect the above-mentioned metathetical reactions, it is preferable to simultaneously add, to an aqueous dispersion containing silica previously dispersed therein, an aqueous silicate solution, an aqueous metal salt solution and an aqueous solution containing the alumina component, while allowing a reaction. The above-mentioned metathetical reaction can be carried out at room temperature but, of course, also can be carried out upon heating at a temperature of up to, for example, about 95°C. The preferable pH range of the reaction during the simultaneous addition is 5 to 10, most preferably especially 6 to 9. If necessary, the pH of the reaction mixture can be controlled by the addition of an acid or alkali, to maintain the above-mentioned pH range. The above-mentioned simultaneous addition of the reactants allows the formation of precipitated aluminosilicate having a composition substantially corresponding to that of the aqueous solution. The precipitates thus formed are separated, or optionally, are heated in the presence of water, to obtain a white or pale-colored fine powder. As the oxidizing agent (i) of the component (b), potassium persulfate, potassium monopersulfate, sodium persulfate, ammonium persulfate, diperoxydodecane diacid, and magnesium perfumarate, are included as representative examples. Among the above, persulfates such as sodium persulfate, potassium persulfate, ammonium persulfate, and potassium monopersulfate; organic peracids such as diperoxydodecane diacid, and magnesium perfumarate, and salts thereof, are preferred. As the plant extract (ii) of the component (b), an extract of Salvia officinalis L. and Rosmarinus officinalis L., To obtain solvent extracts from these plants, as the plant, either the whole grass or the respective sections of plants such as leaves, plant skin, flowers, fruit skin, fruit, root stalk, or root may be employed, and the section containing relatively more of the deodorizing effective ingredient of the plant can be selected. When obtaining deodorizing effective ingredients from these plants, known methods can be employed. For example, it is possible to employ the method in which plants dried and then cut and formed into powder, are extracted with at least one polar solvent such as water, ethyl ether, ethylene chloride, dioxane, acetone, ethanol, n-butanol, ethyl acetate, propylene glycol or at least one nonpolar solvent such as n-hexane, petroleum ether, ligroin, cyclohexane, carbon tetrachloride, chloroform, dichloromethane, 1,2-dichloroethane, toluene, benzene, or a mixed solvent of these polar solvents and nonpolar solvents. In this case, as the extraction operation, a conventional method can be employed in which, for example, plants are subjected to maceration in a solvent. The extract obtained by the extraction operation as described above is usually formulated in a deodorizer after evaporation of the solvent, but in some cases, particularly when the solvent is water, ethanol can be also formulated as such in a deodorizer without evaporation of the solvent. Examples of the germicide (iii) of the component (c) include p-chloro-m-xylenol, butyl-m-cresol, o-phenylpheol and α-bromocinnamic aldehyde are preferred. The deodorizer composition of the present invention can be obtained with the above components (a) and (b) as the essential components. These respective components may be formed into powdery or granular products and mixed, the component (a) may be impregnated with the component (b), and a carrier may be impregnated or attached with the component (b) and mixed with the component (a), or further, the components (a) and (b) may be kneaded and granulated under the condition maintained in a solvent. In the deodorizer composition of the present invention, it is preferable to contain the component (a) and the component (b) at a weight ratio of (a)/(b) = 1/99 to 99.99/0.01, more preferably 50/50 to 99.9/0.1, especially 50/50 to 99.5/0.5. Also, if necessary, optional components can be further formulated in the composition. In the composition of the present invention, in addition to the components (a) and (b), optional components such as surfactants, alkali agents, acid substances, dyes, UV-ray absorbers, antioxidants, and polymeric substances can be also formulated, if necessary. A gas having an objectionable odor generally consists of a large number of components. As representative objectionable odor components, nitrogen type gases such as ammonia and amine, and sulfur type gases such as hydrogen sulfide and mercaptans, are known and are generated in large amounts. Nevertheless, since these nitrogen type and sulfur type objectionable odor components differ in behavior, an effective deodorizing base material for both objectionable odor components was not known. In the present invention, by using the component (a) and the component (b), it is now possible to deodorize various objectionable odors. The performances demanded of deodorizers include, in addition to effects against various objectionable odors, a rapid deodorizing speed and large deodorizing capacity, i.e., long-term persistency. In the present invention, the component (a), provides a deodorizing effect against various objectionable odors, and further, by using the component (b) in combination therewith, the deodorizing speed and the deodorizing capacity are improved. Of the porous substances of the component (a), aluminosilicates in particular are considered to have the characteristics of a solid acid and solid acid group, and it has been reported that the acidity varies depending on the content of alumina in silica-alumina type catalysts, and that the acidity differs depending on the ratio of the contents of alumina and silica [Kozo Okabe: Acid Base Catalyst, p. 183 (1967)]. Further, since the aluminosilicate has a structure in which acidic SiO₂ and basic metal oxides are bound together, it has basic and acidic polarities and is considered to exhibit a deodorizing effect against objectionable odor components based primarily on a chemical adsorption and chemical reaction. On the other hand, porous substances having a specific surface area of 100 m²/g or more as represented by activated charcoal have an excellent physical adsorption. The deodorizing mechanism in the deodorizer composition of the present invention has not been defined, but it is considered that the physical adsorption proceeds at a very rapid speed until reaching an equilibrium, and subsequently, a chemical reaction occurs. That is, by combining a porous substance of the component (a) and the component (b), a rapid adsorption of objectionable odor onto a porous substance with a large specific area, and a chemical reaction of the adsorbed objectionable odor with the component (b), are considered to act synergetically, thereby effectively supplying a stronger deodorization effect. Also, the objectionable odor trapped by the adsorption and chemical reaction will not be released as an odor, and it is considered that a release of an odor, which is a drawback of a deodorization by physical adsorption, is inhibited to improve the durability of the deodorizing effect. According to the deodorizer composition of the present invention, by using the component (a) and an oxidizing agent (i) as the component (b) in combination, a stronger deodorizing power can be exhibited than in the case where each is used alone, but the deodorizing effect can be exhibited more rapidly and the persistency of the effect is prolonged. In the present invention, by using the component (a), a plant extract (ii), and/or a germicide (iii) as the component (b) in combination, it is now possible to deodorize various objectionable odors. Also, by using a plant extract (ii) of the component (b) in combination, in addition to eliminating various objectionable odors, a deodorizer composition is realized which has a rapid deodorizing speed, large deodorizing capacity, and a high safety factor. Further, by combining a germicide (iii) of the component (b) with the component (a), the deodorizing speed and the deodorizing capacity are improved to provide a deodorizer having a prolonged persistency. Therefore, although various objectionable odor components are exuded from the human body, in the home, and by industry facilities, the deodorizer composition of the present invention rapidly eliminates these objectionable odors and provides a long-term deodorizing effect, and thus can be widely utilized. EXAMPLE The present invention will now be further, illustrated by, but is by no means limited to, the following synthetic Examples of the alumino silicates, Examples of the deodorizer compositions, and results of the evaluation thereof. Synthetic Example 1 A 109 g amount of #3 sodium silicate (SiO₂: 22.0%, Na₂O: 7.0%) and 94 g of sodium hydroxide (NaOH content: 2.35 mole) were dissolved in water to prepare 1 liter of a solution A (SiO₂ content: 0.4 mole). Further, 95 g of zinc chloride (anhydrous salt) and 97 g of aluminum chloride (hexahydrate) were dissolved in water to prepare 1 liter of a solution B (ZnO content: 0.7 mole, Al₂O₃: 0.2 mole). Then, one liter of water was charged into a 5 liter beaker and, while stirring, the solutions A and B were simultaneously added thereto at a feed rate of about 25 cc/min, respectively. The pH of the resultant reaction mixture was 6.9 after the addition. The stirring was further continued, and after aging for 30 minutes, the mixture was heated at a temperature of 85 to 90°C for 2 hours on a water bath. The reaction mixture thus obtained was filtered with aspiration, followed by washing with water and drying at a temperature of 110°C, and the cake thus obtained was sifted through a sieve to obtain zinc aluminosilicate in the form of white particles having a size of 8 to 16 mesh (Tylor). The composition of the three components and the BET specific surface of the resultant particles are shown in Table 2, together with the data of the following Synthetic Examples. Synthetic Example 2 In the same manner as in Synthetic Example 1, 139 g of #3 sodium silicate (SiO₂: 22.0%, Na₂O: 7.0%) and 88 g of sodium hydroxide (NaOH content: 2.2 mole) were dissolved in water to prepare 1 liter of a solution A (SiO₂ content: 0.51 mole). Further, 65 g of zinc chloride (anhydrous salt) and 126 g of aluminum chloride (hexahydrate) were dissolved in water to prepare 1 liter of a solution B (ZnO content: 0.48 mole, Al₂O₃: 0.26 mole). Then, one liter of water was charged into a 5 liter beaker and, while stirring, the solutions A and B were simultaneously added thereto at a feed rate of about 25 cc/min, respectively. The pH of the resultant reaction mixture was 8.6 after the addition. The reaction mixture obtained above was treated in the same manner as in Synthetic Example 1, whereby zinc aluminum silicate in the form of particles having a size of 8 to 16 mesh was obtained. Synthetic Example 3 A 273 g amount of #3 sodium silicate (SiO₂: 22.0%, Na₂O: 7.0%) and 60 g of sodium hydroxide (NaOH content: 1.5 mole) were dissolved in water to prepare 1 liter of a solution A (SiO₂ content: 1.0 mole). Further, 34 g of silver nitrate and 225 g of aluminum nitrate (nonahydrate) were dissolved in water to prepare 1 liter of a solution B (Ag₂O content: 0.1 mole, Al₂O₃ content: 0.3 mole). Then, one liter of water was charged into a 5 liter beaker and, while stirring, the solutions A and B were simultaneously added thereto at a feed rate of about 25 cc/min, respectively. The pH of the resultant reaction mixture was 8.9 after the addition. The stirring was further continued, and after aging for 1 hour, the cake thus obtained was sifted through a sieve to obtain silver aluminosilicate in the form of particles having a size of 8 to 16 mesh. Synthetic Example 4 A 77 g amount of #1 sodium silicate (SiO₂: 35.0%, Na₂O: 17.5%) and 24 g of sodium hydroxide (NaOH content: 0.6 mole) were dissolved in water to prepare 1 liter of a solution A (SiO₂ content: 0.45 mole). Further, 216 g of zinc sulfate (heptahydrate) and 75 g of sodium aluminate (Al₂O₃ content: 20.5%, Na₂O content: 19.5%) were dissolved in water to prepare 1 liter of a solution B (ZnO content: 0.75 mole, Al₂O₃: 0.15 mole). Then, one liter of water was charged into a 5 liter beaker and, while stirring, the liquids A and B were simultaneously added thereto at a feed rate of about 25 cc/min, respectively. The pH of the resultant reaction mixture was 6.9 after the addition. The stirring was further continued, and after aging for 30 minutes, the mixture was heated at a temperature of 85 to 90°C for 2 hours on a water bath. The reaction mixture thus obtained was filtered with aspiration, followed by washing with water and drying at a temperature of 110°C, and the cake thus obtained was sifted through a sieve to obtain zinc aluminosilicate in the form of white particles having a size of 8 to 16 mesh.
