Description

  The present invention relates to a deposit removing tool for removing deposits such as dust and dirt from an object such as clothing.

  2. Description of the Related Art Conventionally, for example, a brush has been widely used as a deposit removing tool for removing deposits such as dust and dirt from objects such as clothes and cloth.

  Conventional brushes have a structure in which fine fibrous hairs are implanted in the main body. The brush hair is fibrous animal hair, plant hair, or resin hair. Using such a brush, particles such as dust and dirt adhering to the clothing surface can be removed by a physical action when the hair contacts the clothing surface. Therefore, the conventional brush is used to remove dust and dirt adhering to the clothing surface at the entrance or the like before entering the room when returning home from the outside.

  Further, in recent years, a product that has a new effect has been developed by combining an apparatus for generating a gaseous substance with a brush. For example, there are brushes and brush-mounted dryers combined with means for releasing gaseous substances such as negative ions and ozone.

  For example, Japanese Unexamined Patent Publication No. 2003-61736 (Patent Document 1) describes a hair dryer with a brush in which an ion discharge port for discharging negative ions is formed separately from an air discharge port. In this hair dryer with a brush, warm air containing negative ions is blown onto the hair to treat the hair as well as drying and setting the hair.

  Japanese Patent Laying-Open No. 2007-105144 (Patent Document 2) describes a hair setter in which a discharge unit and a transformer for generating negative ions are arranged in a main body. An attachment such as a blow brush or a roll brush can be attached to the body of the hair setter as an attachment. Negative ions are blown out by dry air and supplied to the hair.

  Japanese Patent Laying-Open No. 2005-95638 (Patent Document 3) describes a hair styling brush including an ion generator that generates negative ions.

  Japanese Patent Application Laid-Open No. 60-160904 (Patent Document 4) describes a hairbrush that generates negative ions.

  Japanese Utility Model Publication No. 3-74819 (Patent Document 5) describes a hair brush in which an ozone generator and a motor fan are housed in a hollow portion of a brush support body in order to sterilize, deodorize, and beauty hair and scalp. Has been.

  As described above, in the conventional brush, by combining the brush with a means for releasing gaseous substances such as negative ions and ozone, dust attached to the surface of the clothes is removed, and the hair is trimmed. It is possible to irradiate hair and scalp with ozone and deodorize with ozone, or supply negative ions to hair.

  By the way, the adhering substances adhering to objects such as clothes and cloth are not only solid components such as dust. For example, odorous substances that generate odor may adhere to clothes and the like. Odorous substances are detached from objects such as clothes and become odorous.

  In recent years, people's desire for cleanliness has increased rapidly, and in particular, there has been an increasing need for effective removal of odors. Typical examples of odors that adhere to objects such as clothing include cigarette odors (mainly ammonia-based, acetic acid-based, aldehyde-based, and nicotine-based), and odors emitted from the human body include sweat odor (mainly Fatty acid components such as valeric acid), aging odors (mainly nonenal), and food-related odors include cooking odors (mainly trimethylamine), spoilage odors (mainly hydrogen sulfide), etc. It is done.

  By using a conventional brush to remove dust on the surface of an object such as clothing, odorous substances adhering to the dust can be removed together with the dust from the surface of the object.

In Japanese Patent No. 3680121 (Patent Document 6), an ion generator is mounted and H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O as negative ions in the indoor air. _{^{2 - (H 2 O) n}} (n is an arbitrary natural number) emits an air purifier or air conditioner to perform the cleaning of the air is described by the effect of ions. These positive ions and negative ions released into the air chemically react between the positive ions and the negative ions to become hydrogen peroxide (H ₂ O ₂ ) or a hydroxyl radical (.OH) as an active substance. . It is known that hydrogen peroxide or hydroxyl radical can inactivate suspended particles or sterilize suspended bacteria by performing an oxidation reaction that extracts hydrogen from suspended particles or suspended bacteria.

In addition, US Pat. No. 4,210,847 (Patent Document 7) describes a configuration of an ion wind device in which a corona discharge needle is disposed at the center of a cylindrical tube and a counter electrode is disposed. This ion wind device is disposed as a discharge phenomenon generating electrode for generating a discharge phenomenon, such as a needle-shaped electrode having a pointed tip, for example, formed in a mesh shape and facing the needle-shaped electrode. An ion wind device composed of a counter electrode is described. The needle-type electrode and the counter electrode are arranged at an interval.

  However, the odor component is attached to the surface of an object such as clothing or cloth at the molecular level, and is extremely small compared to dust. Therefore, especially when the object is a fiber structure such as clothing or cloth, the odor component is removed from the object by the physical action of a brush composed of fibrous animal hair, plant hair, or resin hair. It is difficult to remove from the surface.

  In order to remove such odors that cannot be removed using a brush, conventionally, objects such as clothes are washed with water and a detergent. By washing the object and removing odor components from the object, odors can be removed from the object.

  However, removing odors by washing with water or detergent takes time, and it is necessary to dry objects such as clothes after washing.

  As a method other than washing to remove odorous components from the object, create an environment where strong wind is generated, such as an air shower provided at the entrance of a clean room such as a semiconductor factory or a liquid crystal display factory, and place it on the airflow. A method of blowing off odor components is employed. Thus, if the method of blowing off an odor component is used, the odor component adhering to clothing and cloth can be removed.

  However, it is practically impossible to provide such an air shower device in a general home in consideration of cost, installation location, and the like.

  As another method for removing odors, there is a method of exerting a deodorizing effect by wrapping odors with components of a deodorizing liquid. Deodorant liquids are widely available on the market. For example, products that can remove odors by spraying the deodorant liquid with a spray are on the market.

  However, even if the odorous substance is wrapped with the components of the deodorizing liquid, the odorous substance itself exists, so that the deodorizing substance encapsulating the odorous substance is detached again over time. When the deodorizing substance is detached from the odorous substance, odor is generated again. As described above, by using a deodorizing substance, although a short-term odor suppression effect can be obtained, it is difficult to maintain a long-term removal effect.

  When generating ozone as in the hair brush described in Japanese Utility Model Publication No. 3-74819 (Patent Document 5), odorous substances in hair and scalp can be deodorized by ozone, but ozone itself is unique. The odor is emitted. Ozone is also harmful.

  Further, a hair dryer with a brush described in JP-A-2003-61736 (Patent Document 1), a hair setter described in JP-A-2007-105144 (Patent Document 2), and JP-A-2005-95638 (Patent Document). 3) and a brush for supplying negative ions (negative ions) to hair, such as a hair brush described in Japanese Patent Application Laid-Open No. 60-160904 (Patent Document 4), the hair and scalp by negative ions. Although we can increase the moisture, we cannot remove odors with negative ions.

  Moreover, in these brushes, since ions and ozone are supplied to the hair together with air, the ions and ozone are dispersed together with the airflow. By dispersing ions and ozone together with the air flow, deposits such as dust are also dispersed. When an odor component adheres to dust or the like, the odor component is dispersed by the dispersion of the dust or the like, and odor is generated in a wide range. Further, ozone having a deodorizing effect is also dispersed in a wide range together with the air flow, so that the odor component adhering to the hair cannot be deodorized.

  Accordingly, an object of the present invention is to provide a deposit removal tool that can effectively remove odors from an object.

The deposit removing tool according to the present invention includes an deposit peeling member for peeling an deposit adhering to an object from the object, and H ⁺ (H ₂ O) _m (m is an arbitrary positive ion). A natural number) and an ion generator that generates O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) as negative ions, and positive ions and negative ions released from the ion generator, and an object peeling member. And a staying area forming unit for staying in a predetermined area formed on the surface of the object.

  Deposits such as dust, dirt, pollen, and odorous substances that generate odor are physically peeled off the target by the deposit peeling member.

  The deposit separated from the object by the deposit separating member is retained in a predetermined area on the surface of the object by the retention area forming section together with positive ions and negative ions released from the ion generating section. In this way, positive ions and negative ions are retained in a predetermined region on the surface of the object while maintaining the concentration without being dispersed. The deposits, positive ions, and negative ions that have been peeled off from the object are liable to collide with each other by being retained in a predetermined region.

  Further, positive ions and negative ions are retained in a predetermined region formed on the surface of the object without being dispersed, thereby contacting the surface of the object or from the surface of the object. It becomes easy to get inside. In this way, positive ions and negative ions are likely to come into contact with adhering substances such as odor components remaining on the surface or inside of the object without being exfoliated by the adhering substance peeling member.

  When the deposit peeled off from the object or the deposit remaining on the surface of the object collides with positive ions and negative ions, the deposits, positive ions and negative ions interact with each other. When the deposit is an odor substance that generates odor, the odor substance is decomposed by interacting with positive ions and negative ions. Thus, the deposit | peeling peeled from the target object is deodorized using a chemical effect | action.

  As described above, the deposit removing tool of the present invention physically peels off the deposit from the object by the deposit peeling member, and maintains the positive ion and negative ion concentrations on the surface of the object. The debris is deodorized by a chemical interaction between positive ions, negative ions, and deposits.

  By doing in this way, the deposit | attachment removal tool which can remove the odor of a deposit | attachment effectively can be provided.

  In the deposit removal tool according to the present invention, it is preferable that the stay region forming portion is formed by a portion of the deposit peeling member so as to surround the ion generating portion.

  As described above, since the retention region forming part is formed so as to surround the ion generating part, it is difficult to disperse the positive ions and negative ions generated in the ion generating part, and the concentration of positive ions and negative ions can be easily maintained. . In addition, since the stay region forming portion is formed by the deposit peeling member, the deposit is removed together with positive ions and negative ions before the deposit peeled from the target by the deposit peeling member is dispersed. It can stay in the area.

  In the deposit removing tool according to the present invention, the ion generation unit includes a positive ion generation unit for generating positive ions and a negative ion generation unit for generating negative ions, It is preferably formed separately from the negative ion generation part.

  By doing in this way, a voltage is separately applied to a positive ion generation part and a negative ion generation part, and the generation amount of a positive ion and the generation amount of a negative ion can be adjusted, respectively.

  The deposit removing tool according to the present invention preferably includes a separating member arranged so as to separate the positive ion generating part and the negative ion generating part.

  By doing in this way, it prevents that the positive ion which generate | occur | produced in the positive ion generation | occurrence | production part, and the negative ion which generate | occur | produces in the negative ion generation part collide immediately after generation | occurrence | production, and in the predetermined area | region formed by the residence area | region formation part It is possible to reduce positive ions and negative ions that are neutralized and deactivated before reaching.

  In the deposit removal tool according to the present invention, the ion generator preferably includes an ion wind generator that generates an ion wind.

  By doing in this way, positive ions and negative ions can efficiently reach a predetermined region formed on the surface of the object. Moreover, since wind can be generated without providing a blowing means such as a propeller fan or a cross flow fan, it is possible to provide a deposit removing tool capable of saving space and reducing power consumption.

  The deposit removing tool according to the present invention includes a polarity detection unit for detecting the polarity of the charge on the surface of the object, and the ion generator is configured so that the deposit removing tool is relatively positioned along the surface of the target. A static ion generator that is disposed on the front side relative to the target object along the relative movement direction of the deposit removing tool, and the polar ion detector detects the static ion generator. It is preferable to generate ions having a polarity opposite to the polarity of the charged surface of the object.

  The polarity of the surface of the object is detected in advance by the polarity detection unit, and ions of the opposite polarity to the polarity of the surface of the object are generated by the ionization ion generation unit arranged on the front side of the ion generation unit. Thus, first, the charge on the surface of the object can be neutralized with the ions generated by the static elimination ion generator. When the charge on the surface of the object is neutralized by the ions generated by the static elimination ion generator, the surface of the target is in a neutralized state. Thereafter, positive ions and negative ions generated in the ion generation unit are retained in a predetermined region formed on the surface of the object.

  By doing in this way, the deodorizing effect by a positive ion and a negative ion can be heightened.

  The deposit removing tool according to the present invention includes a contact detection unit for detecting that the deposit peeling member is in contact with the surface of the object, and the ion generating unit includes the deposit peeling member of the object. It is preferable that ions are generated when the contact detection unit detects contact with the surface.

  By doing in this way, power consumption can be suppressed.

  As described above, according to the present invention, it is possible to provide a deposit removal tool that can effectively remove the odor of deposits.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The inventor of the present application, as an activated gas released into the space, generally called atmospheric ions, ions generated by ionizing oxygen and water vapor in the air by plasma discharge are objects such as clothing and cloth. It has been found that it has a deodorizing effect on odors adhering to the surface.

An ion generator for generating such ions has already been put into practical use. This ion generator generates positive ions H ⁺ (H ₂ O) _m (m is a natural number) and negative ions O ₂ ⁻ (H ₂ O) _n (n is a natural number) in the air. These positive ions and negative ions have a form in which a plurality of water molecules are attached around a hydrogen ion (H ⁺ ) or an oxygen ion (O ₂ ⁻ ), that is, a so-called cluster ion.

  An air purifier or an air conditioner equipped with a conventional ion generator emits ions into the space in order to enhance the effect of inactivation and sterilization of the suspended particles or suspended bacteria in the space.

  However, in an air cleaner equipped with a conventional ion generator, even if the ions released into the air are positive ions and negative ions that have the effect of inactivating and sterilizing the floating bacteria, the deodorizing effect Was not obtained. This is because the lifetime of the ions generated by the ion generator is short, so the amount of positive ions and negative ions released into the air from the air purifier or air conditioner reaches the surface of clothing, cloth, etc. This is because of a decrease in As mentioned above, the odor source is attached to clothing and fabrics, so if the ions do not reach the clothing and fabrics in the amount necessary to decompose the odor components, the deodorizing effect by the ions Cannot be obtained.

  Therefore, in order to enhance the effect of removing odors attached to clothes and cloth, it is necessary to irradiate clothes and cloth directly with ions in a high ion concentration state. By doing in this way, the effect | action of an ion appears notably and it becomes possible to remove odor by the chemical effect which a positive ion and a negative ion exert on an odor component. In this way, in order to enhance the effect of removing odors attached to clothes and cloths of positive ions and negative ions, rather than releasing ions to the space as in the case of cleaning indoor air, It is more effective to spray positive ions and negative ions on clothes and fabrics.

  Here, the effect of the positive ions and the negative ions on odors attached to clothes and fabrics will be described.

The ions of H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n generated in the ion generating element chemically react to generate H ₂ O ₂ or .OH (OH radical) as an active species. To do. Since H ₂ O ₂ or .OH exhibits a very strong activity, it is possible to remove odors attached to clothes and fabrics. Here, .OH is a kind of active species and represents radical OH. Generation of H ₂ O ₂ or _.OH from H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n is represented by the following chemical formula.

H ⁺ (H ₂ O) _m + O ₂ ⁻ (H ₂ O) _n
→ OH + (1/2) O ₂ + (m + n) H ₂ O (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 · OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)
The inventor of the present application has discovered through various verifications that these ions have a deodorizing effect. Below, the verification experiment which concerns on the deodorizing effect of the ion which the inventor of this application performed is demonstrated.

(Verification experiment 1)
A sensory evaluation test was conducted on a test cloth to which tobacco odor was adhered by a six-step odor intensity display method by six panelists. The 6-level odor intensity display method is a method for quantifying the level of odor, dividing the odor intensity into 6 levels and expressing it with a numerical value from 0 to 5. In order to establish regulatory standards in the Odor Control Law It is used as a basic standard.

First, the odor of tobacco was attached to the test cloth (polyester cloth), and then the test cloth was blown. The blower irradiates the test cloth with H ⁺ (H ₂ O) _m (m is a natural number) as positive ions generated from the ion generating element and O ₂ ⁻ (H ₂ O) _n (n is a natural number) as negative ions. For the two cases, ie, when the test cloth is not irradiated with ions, the blower was operated for 2 hours, respectively. The odors of the test cloths blown under each condition were compared by a sensory test using a six-step odor intensity display method. The concentration of ions irradiated onto the test cloth was 10,000 positive ions and negative ions / cm ³ , respectively, and the irradiation time in the case of irradiation with ions was 2 hours.

  Table 1 is a table | surface which shows the result of the sensory test by the 6-step odor intensity display method about said test cloth.

As shown in Table 1, immediately after the cigarette odor was adhered, the odor intensity of the test cloth was 4.8. When this test cloth was blown for 2 hours without irradiating with ions, the odor intensity was 3.9. On the other hand, when the test cloth having an odor intensity of 4.8 was blown while irradiating positive ions and negative ions with an ion concentration of 10,000 ions / cm ³ for 2 hours, the odor intensity was 3.3. Thus, it can be seen that the odor intensity is greatly reduced by the action of ions.

  When the odor intensity display value is 1, the actual odor is 10 times different. That is, when the odor intensity display is changed from 4 to 3, the odor becomes 1/10. From this result, it can be determined that the positive ions and the negative ions have a deodorizing effect.

  Utilizing the deodorizing effect of the above positive ions and negative ions, when the odor of cigarettes adheres to the cloth fabric, the odor intensity of odor can be reduced by irradiating the above positive ions and negative ions. , Odor can be suppressed.

  Not only the smell of tobacco but also the irradiation of both positive ions and negative ions as described above, aging odor (nonenal), cooking odor typified by fish odor (trimethylamine), toilet odor and egg odor ( The inventors of the present application conducted a similar test for hydrogen sulfide). As a result, although there was some difference in the odor removal effect, it was confirmed that the positive ions and the negative ions had a deodorizing effect for any odor component.

(Verification experiment 2)
Oxidation experiment of the odor component adhering to the test cloth was performed by chemiluminescence method (chemical luminescence).

  The purpose of this verification experiment is to verify how ions act on odors that adhere to clothing and fabrics.

The principle of the chemiluminescence method will be described. The substance as the evaluation target emits energy as light when returning from the excited state to the ground state. The chemical luminescence method is a method for observing the phenomenon in which the target substance returns from the excited state to the ground state by measuring the intensity of the light emitted at this time. The emitted light is observed as fluorescence or phosphorescence, for example, when ultraviolet light is used as a method for forming an excited state. In the verification experiment 2, the target material is irradiated with ions to form an excited state. However, since chemiluminescence has an extremely weak emission intensity compared to fluorescence and phosphorescence, a liquid-cooled ultrasensitive photomultiplier tube was used for detection of chemical luminescence. Therefore,
(Degree of oxidation of the substance attached to the cloth) ∝ (Chemical luminescence intensity)
It becomes the relationship.

  As an evaluation test, linoleic acid was applied and adhered as an odor substance to a polyester test cloth. The test cloth was irradiated with ions under the following three conditions. Each condition was performed three times, and reproducibility was also confirmed.

(1) 600,000 ions / cm ³ + air blowing (2) 60,000 ions / cm ³ + air blowing (3) Air blowing only (the ion generating element is not operated)
When ion irradiation was performed, irradiation was performed for 12 hours. The reason for the long irradiation time is to increase the measurement accuracy of chemiluminescence. As the number of ions, the numbers of positive ions and negative ions are shown.

  FIG. 1 is a diagram showing the degree of oxidation of a substance attached to a cloth by a chemiluminescence method (chemical luminescence).

  As shown in FIG. 1, the emission intensity increases as the number of irradiated ions increases. The vertical axis represents the photomultiplier tube count associated with chemiluminescence. As described above, this count reflects the degree of oxidation of the attached linoleic acid. The emission intensity of chemical luminescence increases with a positive correlation with the ion concentration irradiated onto the test cloth. That is, it shows that the oxidation reaction of the substance (linoleic acid) adhering to the cloth is proceeding by ion irradiation. In addition, when only the air is blown without operating the ion generating element, the chemical luminescence intensity is hardly changed even after 12 hours, and in the absence of ions, the oxidation reaction of linoleic acid occurs. I knew it was n’t there.

  As described above, the inventors of the present application have confirmed that the ions oxidatively decompose the substance attached to clothing and cloth.

(Verification experiment 3)
Next, the ion concentration dependency of the removal property of the ions on odors attached to clothing and cloth was evaluated.

First, JIS standard cloth (polyester (product code: 670110)) is used as a test cloth, washed with a commercially available detergent, cut into a size of 10 cm × 10 cm = 100 cm ² , and 10 sheets of acetic acid are attached together as 10 sheets. I let you. 1 mg of acetic acid adhered to each test cloth. This test cloth was suspended in a 1 m ³ test box and left for 2 hours while blowing air. The test cloth was left under the following conditions (1) to (5). Under the conditions (2) to (5), the ion generating element was driven and the test cloth was exposed to ions for 2 hours. Thereafter, the test cloth was sealed in an aluminum pack and allowed to stand at 60 ° C. for 30 minutes, and then the amount of acetic acid re-released from the test cloth was measured. In addition, the measurement of acetic acid concentration was performed using a detector tube NO. 81L (0.488 μg can be identified) was used.

(1) No generation of ions (2) Ion concentration 5000 / cm ³
(3) Ion concentration 10,000 / cm ³
(4) Ion concentration 25000 / cm ³
(5) Ion concentration 88000 / cm ³
That is, the odor removal characteristics under five conditions with different ion concentrations are evaluated.

  FIG. 2 is a graph (A) showing the concentration dependence of the acetic acid re-release amount of the test cloth and the acetic acid re-release amount of the test cloth that was blown without irradiating the ions. It is a figure (B) which shows the density | concentration dependence of the reduction | decrease amount of acetic acid re-release calculated | required by subtracting the acetic acid re-release amount of a test cloth when performing.

  As shown in FIG. 2A, the amount of acetic acid re-released from the test cloth blown while irradiating with ions decreased as the concentration of irradiated ions increased. From this result, it was found that the above positive ions and negative ions can suppress the re-release of acetic acid and prevent the odor component of acetic acid from detaching from the test cloth and causing odor. That is, it has been found that the positive ions and the negative ions have a removing effect on the attached odor of acetic acid.

  Further, as shown in FIG. 2B, since the concentration of ions irradiated on the test cloth and the reduction amount of acetic acid re-release are positively correlated, the effect of removing acetic acid adhering odor is due to the action of ions. I understand that.

  FIG. 3 is a graph showing the ion concentration dependence of the time required to remove 0.1 mg of acetic acid adhering to the test cloth. In FIG. 3A, the required time on the vertical axis is shown logarithmically, and in FIG. 3B, the result shown in FIG. 3A is expanded by the range of required time 0 to 2.5. Show.

  As shown in FIGS. 3A and 3B, the time required to remove 0.1 mg of acetic acid adhering to the test cloth is shortened as the ion concentration increases. For example, when the ion concentration is 380,000, it was found that 0.1 mg of acetic acid attached to the test cloth can be removed in 0.017 hours, that is, about 1 minute.

From the results of the above verification experiments 1 to 3, H ⁺ (H ₂ O) _m (m is a natural number) as a positive ion that chemically interacts to generate H ₂ O ₂ or an OH radical, and O ₂ as a negative ion. _{^{- (H 2 O) n (}} n is a natural number), by oxidative decomposition of odor components adhering to the object such as clothes and fabrics, it was confirmed that the removal of odor of the object.

That is, the ion generating element generates H ⁺ (H ₂ O) _m as positive ions and O ₂ ⁻ (H ₂ O) _n as negative ions. OH is generated by the interaction between the generated positive ions and negative ions (chemical formulas (1) to (3)). This OH acts on the odor component, that is, the C—C bond, C═C bond, C═O bond, etc. of the organic compound that is the source of odor, thereby decomposing these bonds, thereby eliminating the odor An effect is obtained. In the following, the chemical action of the decomposition action of .OH on a typical odor source is shown.

Decomposition of acetic acid:
CH ₃ COOH + 8 · OH → 2CO ₂ + 6H ₂ O (4)
Decomposition of acetaldehyde:
CH ₃ CHO + 10 · OH → 2CO ₂ + 7H ₂ O (5)
Like conventional air conditioners and air purifiers, H ⁺ (H ₂ O) _m as positive ions and O ₂ ⁻ (H ₂ as negative ions for the purpose of inactivating particles existing in the air conditioning target space. O) When _n is generated, ions are generated in a relatively wide space, so that the ion concentration in the air-conditioning target space is about 10,000 / cm ³ .

On the other hand, the ^H + _(H 2 _{O) m} as positive ions in order to remove the odor adhering to the clothing and textiles, _O ² as a negative ion - if _(H 2 _O) is to generate an _n, air conditioning Compared with the case where ions are emitted into the air-conditioning target space using a vacuum cleaner or an air purifier, ions are irradiated onto a small area, so that an environment with a high ion concentration can be achieved. If the ion concentration is increased, as shown in the result of the verification experiment 3, the removal characteristic against odor attached to the object such as the test cloth is improved.

As shown in FIG. 3, in the case of directly irradiating an object such as clothing or cloth with ions, by making the ion concentration to be 100,000 / cm ³ or more, the removal characteristic for the attached odor is greatly improved. improves. In order to irradiate clothing and cloth with an ion concentration of 100,000 ions / cm ³ or more, the distance between the generating element generating positive ions and negative ions and the clothes or cloth should be within 1 m. desirable.

  Based on such considerations, embodiments of the present invention will be described below.

(First embodiment)
FIG. 4 shows a front view (A) showing the entire brush as a first embodiment of the present invention, and a sectional view when the brush shown in FIG. 5B is a bottom view (C) when the brush shown in FIG. 4A is viewed from the direction indicated by the arrow C. FIG. In FIG. 4B, illustration of the hair planted on the handle side with respect to the ion generating element is omitted.

  As shown in FIGS. 4A to 4C, the brush 1 as an adhering material removing tool is provided on a plate-like main body 101, a handle 102 connected to the main body 101, and one surface of the main body 101. The hair 110 as an attached substance peeling member, and the ion generating element 130 and the ion as an ion generating part arranged on one surface of the main body 101 so as to be surrounded by the hair 110 planted in the main body 101 It is comprised from the drive means of the generating element 130. FIG. The handle 102 may be formed integrally with the main body 101.

  The main body 101 of the brush 1 is made of wood or resin. The hair 110 is fibrous animal hair, plant hair, or resin hair.

  The bristles 110 are planted so as to form a substantially rectangular staying area 120 as a predetermined area on one surface of the main body 101. Of the large number of bristles 110, the bristles 111 forming the stay region 120 are an example of a stay region forming part. The ion generating element 130 is disposed in the staying region 120. The ion generating element 130 generates positive ions and negative ions by an electrical method using a plasma discharge phenomenon.

  FIG. 5 is a perspective view (A) showing the whole of the ion generating element provided in the brush, a perspective view (B) showing the inside of the main body of the ion generating element, and the inside of the ion generating element shown in (B) of FIG. It is sectional drawing (C) when seeing from the direction of CC line.

  As shown in FIG. 5A, the ion generating element 130 is accommodated in a synthetic resin main body 131 formed in a flat, substantially rectangular parallelepiped shape. In the main body 131 of the ion generating element 130, two substantially circular openings 132 are formed side by side in the longitudinal direction on one wide surface. The ion generating element 130 emits positive ions from one of the two openings 132 and generates negative ions from the other. In addition, a metal terminal portion 133 to which a high voltage for operating the ion generating element 130 is supplied is provided on one side surface of the main body 131. The approximate dimensions of the ion generating element 130 are about 7 cm × 2 cm × 1 cm.

  As shown in FIGS. 5B and 5C, the ion generating element 130 includes a substrate 134 in the main body 131, a positive electrode 135 as a positive ion generating portion provided on the substrate 134, and a negative ion generating portion. As a negative electrode 136 and a ground electrode 137. The substrate 134 is a substantially rectangular plate and is made of an insulating material. The positive electrode 135 and the negative electrode 136 are round bar-shaped electrodes with sharpened tips. The positive electrode 135 and the negative electrode 136 are respectively passed through two through holes 134a formed in the substrate 134, protruded to one surface of the substrate 134, and fixed to the substrate 134 using solder or an adhesive.

  The ground electrode 137 is a plate-like electrode having a surface area slightly smaller than that of the substrate 134, and is fixed to the substrate 134 at a predetermined interval so as to face the substrate 134. The ground electrode 137 is fixed to the substrate 134 with four legs 137a (only three legs 137a are shown in FIG. 5B) extending substantially in the four directions of the ground electrode 137. The four leg portions 137a of the ground electrode 137 are respectively inserted into the four through holes 134b formed in the substrate 134, and the leg portions 137a are fixed with solder or adhesive.

  The ground electrode 137 has two substantially circular openings 137b. When the ground electrode 137 is fixed to the substrate 134, the positive electrode 135 and the negative electrode 136 are fixed at a substantially central position of the opening 137 b of the ground electrode 137. An edge 137c of the opening 137b of the ground electrode 137 is bent toward the substrate 134 side. When the positive electrode 135, the negative electrode 136, and the ground electrode 137 are fixed to the substrate 134 and accommodated in the main body 131, the two openings 132 formed in the main body 131 and the two openings 137 b formed in the ground electrode 137. Are arranged almost concentrically.

The ground electrode 137 of the ion generating element 130 is connected to the ground potential, a positive high voltage is applied to the positive electrode 135, and a negative high voltage is applied to the negative electrode 136. When a high voltage is applied to each of the positive electrode 135 and the negative electrode 136, the edge 137 c of the opening 137 b of the ground electrode 137 becomes a strong electric field, and plasma discharge is generated from the ground electrode 137. Oxygen and water vapor in the air are ionized by plasma discharge to generate ions. Control is performed so as to suppress the generation of ozone, which is a harmful substance, as much as possible by optimizing the electrode structure and applied voltage. The ions that are most stably generated at this time are positive ions H ⁺ (H ₂ O) _m and negative ions O ₂ ⁻ (H ₂ O) _n . As a result of analyzing the generated ions by mass spectrometry and the like, the generation of ions other than these has hardly been confirmed. Of the two openings 132 formed in the main body 131 of the ion generating element 130, positive ions H ⁺ (H ₂ O) _m are emitted from the opening 132 provided with the positive electrode 135, and the negative electrode 136 is provided. From 132, negative ions O ₂ ⁻ (H ₂ O) _n are released.

As described above, the ions of H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n generated in the ion generating element chemically react with each other to form an active species of H ₂ O ₂ or .OH (OH radical). ) Is generated. As shown in the above-described verification experiments 1 to 3, H ₂ O ₂ or .OH exhibits extremely strong activity, and therefore can remove odors attached to clothes and fabrics. Therefore, both positive ions and negative ions are generated and irradiated. In the case of the release of negative ions alone, no interaction occurs, so that no chemical reaction occurs to generate H ₂ O ₂ or .OH (OH radical) which is an active species. Therefore, the removal characteristic with respect to the attached odor becomes very small.

  As shown in FIG. 4B, when the user holds the brush 1 with the handle 102 so that the hair 110 of the brush 1 is in contact with the clothing 300 as an object, the surface of the clothing 300, the hair 111, The staying region 120 is surrounded by the ion generating element 130 and the surface of the main body 101 on which the hair 110 is planted. The deposits peeled off from the clothing 300 by the hairs 110 stay in the stay region 120. Positive ions and negative ions generated by the ion generating element 130 also stay in the staying region 120.

  In the staying region 120, positive ions and negative ions chemically interact on the surface of the deposit such as dust peeled off from the clothing 300 to remove the odor of the deposit. Further, the positive ions and the negative ions also chemically interact on the surface of the garment 300 to decompose odorous substances that have not adhered to the surface of the garment 300 and have not been peeled off by the hair 110, thereby reducing the odor of the garment 300. Remove.

As described above, the brush 1 according to the first embodiment includes the hair 110 for peeling the deposits attached to the clothing 300 from the clothing 300, and H ⁺ (H ₂ O) _m (m is an arbitrary ion). Natural number) and O ₂ ⁻ (H ₂ O) _m (m is an arbitrary natural number) as negative ions, and positive ions, negative ions, and hairs 110 emitted from the ion generating element 130. And bristles 111 for retaining the deposits peeled from the clothing 300 in a residence region 120 formed on the surface of the clothing 300.

  Deposits such as dust, dirt, pollen, and odorous substances that generate odor are physically peeled from the garment 300 by the hair 110.

  The deposits peeled off from the garment 300 by the hair 110 are retained in the staying region 120 on the surface of the garment 300 by the hair 111 together with positive ions and negative ions released from the ion generating element 130. In this way, positive ions and negative ions are retained in the retention region 120 on the surface of the garment 300 while maintaining the concentration without being dispersed. The deposits, positive ions, and negative ions that have been peeled off from the clothing 300 are likely to collide with each other by being retained in the retention region 120.

  Further, the positive ions and the negative ions are retained in the retaining region 120 formed on the surface of the garment 300 without being dispersed, thereby contacting the surface of the garment 300 or from the surface of the garment 300. It becomes easy to get inside. In this way, positive ions and negative ions can easily come into contact with adhering substances such as odor components that are not peeled off by the hair 110 and remain on the surface or inside of the clothing 300.

  When the deposits peeled off from the clothing 300 or the deposits remaining on or inside the clothing 300 collide with positive ions and negative ions, the deposits, positive ions and negative ions interact with each other. When the deposit is an odor substance that generates odor, the odor substance is decomposed by interacting with positive ions and negative ions. In this way, the deposits peeled off from the clothing 300 are deodorized using a chemical action.

  As described above, the brush 1 according to the first embodiment is formed on the surface of the garment 300 while peeling the deposits physically from the garment 300 by the bristles 110 and maintaining the positive ion and negative ion concentrations. The detained matter is deodorized by the chemical interaction between the positive ions, the negative ions, and the adhering matter.

  By doing in this way, the brush 1 which can remove the odor of a deposit | attachment effectively can be provided.

  In the brush 1 of the first embodiment, the hair 111 is formed by a part of the hair 110 so as to surround the ion generating element 130.

  Thus, since the hair 111 is formed so as to surround the ion generating element 130, it is difficult to disperse the positive ions and negative ions generated by the ion generating element 130, and the concentration of positive ions and negative ions can be easily maintained. . Further, since the hairs 111 are formed by the hairs 110, the attached materials are retained in the staying region 120 together with positive ions and negative ions before the attached materials separated from the clothing 300 by the hairs 110 are dispersed. Can do.

  Moreover, in the brush 1 of 1st Embodiment, the positive electrode 135 and the negative electrode 136 are formed separately. Therefore, by making the magnitude and waveform of the voltage applied to each of the positive electrode 135 and the negative electrode 136 different, the amount of positive ions generated at the positive electrode 135 and the negative ions generated at the negative electrode 136 are different. The amount can be different.

  Objects such as clothing and cloth may be charged, particularly in an environment with low humidity. Whether the polarity of static electricity that charges an object is positive or negative depends on the type of the substance, and follows a rule called a charge train. There is a charge train as a law relating to a charge sign of an electrical insulator such as a fiber. Since charging is a surface phenomenon in clothing and fabrics, it is affected by sample differences, surface roughness, measurement methods, and environmental conditions, but it has a relatively good reproduction between the charged columns that have been reported for a long time. There is sex. In other words, glass, nylon, wool, rayon, cotton, silk, polyester, acetate, acrylic, metal, polystyrene, polypropylene, polyethylene, and polyvinylidene chloride are listed in order of strong positive tendency. 2nd edition, Textile Society, Maruzen Co., Ltd.).

  In particular, polyester-based synthetic fibers are used in clothing and fabrics in general households. Polyester-based synthetic fibers tend to be negatively charged on the surface in a dry state in winter (humans are positively charged) and generate static electricity.

  If there is a charge on the surface of an object such as clothing or cloth, the effect of removing odors by ions may be reduced.

As described above, the odor adhering to the object is decomposed and removed by the chemical reaction between the positive ions and the negative ions irradiated on the object to generate H ₂ O ₂ and OH radicals. For this reason, the odor removal effect by the ions is greatest when the object is irradiated with the same amount of positive ions and negative ions.

Even if the target is irradiated with the same amount of positive ions and negative ions, if the target is charged with static electricity, the irradiated ions and static electricity on the surface of the target are neutralized, and the ions are deactivated. End up. When the surface of the object is positively charged, even if the object is irradiated with the same amount of positive ions and negative ions, the negative ions are neutralized with the negative charge on the surface of the object. The proportion of negative ions is reduced. When the surface of the object is negatively charged, even if the object is irradiated with the same amount of positive ions and negative ions, the positive ions are neutralized with the negative charge on the surface of the object. The proportion of positive ions decreases with respect to. As described above, even when the object is irradiated with the same amount of positive ions and negative ions, if one of the positive ions and the negative ions is smaller than the other, the ratio of generating H ₂ O ₂ and OH radicals decreases. Compared with the case where all of the positive ions and negative ions irradiated to the object chemically react with each other, the effect of removing odors attached to clothes and fabrics is reduced.

  Therefore, in the brush 1 of the first embodiment, the magnitude and waveform of the voltage applied to the positive electrode 135 and the negative electrode 136 are different, and the amount of positive ions generated at the positive electrode 135 and the negative electrode 136 are generated. The amount of negative ions generated may be varied to remove static electricity present on the surface of clothing or cloth.

  As described above, particularly in winter, negative charges are likely to be charged on the surface of an object such as clothing or cloth formed of chemical fibers such as polyester or acrylic. Therefore, for example, in winter, the voltage applied to the positive electrode 135 is made larger than the voltage applied to the negative electrode 136, and the amount of positive ions generated at the positive electrode 135 is negative. Try to be more than the amount of ions. Positive ions are neutralized with the negative charges charged on the surface of the object and deactivated, but since more positive ions are generated than negative ions, Negative ions that are not neutralized can be efficiently used in chemical reactions.

  Further, for example, before using the brush 1, the charged state of the object may be sensed, and the generation ratio of positive ions and negative ions may be adjusted according to the charged state of the object. By sensing the charged state of the object in advance and generating more ions with the opposite polarity to the charged polarity of the object than ions with the same polarity as the charged polarity of the object, the generated ions are efficiently generated. It can be used to remove odors. In this way, the synergistic effect of positive ions and negative ions can be maximized.

  As described above, in the brush 1 of the first embodiment, the ion generating element 130 includes the positive electrode 135 for generating positive ions and the negative electrode 136 for generating negative ions. And the negative electrode 136 are formed separately.

  By doing so, it is possible to adjust the generation amount of positive ions and the generation amount of negative ions by separately applying voltages to the positive electrode 135 and the negative electrode 136, respectively.

  In addition, in 1st Embodiment, although the brush was demonstrated as an attachment removal tool, the attachment removal tool of this invention is a short hair etiquette brush, a toothbrush, a mop, a sponge for tableware, a shoe wiping mat, a foot wiping mat. It may be applied to towels, washing machines and the like.

For example, in the case of a washing machine that stores laundry in a washing tub as clothing and rotates the washing tub in a plane inclined from the horizontal direction, a baffle disposed in the washing tub is an example of the deposit peeling member. . The washing machine has a baffle and a rotatable washing tub for separating the adhering matter adhering to the laundry, and a positive ion of H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and negative. Ion generating element 130 for generating O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) as ions, positive ions and negative ions released from ion generating element 130, baffles, and a washing tub from the laundry By providing the cleaning tank for retaining the peeled deposit in a predetermined area formed on the surface of the laundry, the effect as the deposit removing tool of the present invention can be obtained.

(Second Embodiment)
FIG. 6 shows a front view (A) showing the entire brush as a second embodiment of the present invention, and a cross-sectional view of the brush shown in FIG. 7B is a bottom view when the brush shown in FIG. 6A is viewed from the direction indicated by the arrow C. FIG. In FIG. 6B, illustration of hairs planted closer to the handle side than the ion generating element is omitted.

  As shown in FIG. 6, the brush 2 according to the second embodiment is different from the brush 1 according to the first embodiment in that the brush 2 includes an ion generation unit 140 including a plurality of ion generation elements 140a, 140b, and 140c. Is provided. The ion generating elements 140a, 140b, and 140c are arranged in a line. Moreover, the partition plate 150 is provided as a partition arranged between the ion generating element 140a and the ion generating element 140b and between the ion generating element 140b and the ion generating element 140c. It is desirable that the end portion of the partition plate 150 protrudes by 2 mm or more from the ion generation unit 140.

  Each ion generating element 140a, 140b, 140c constituting the ion generating unit 140 is configured in the same manner as the ion generating element 130 (FIG. 5) included in the brush 1 of the first embodiment, but only one electrode is provided. This is different from the ion generating element 130 in that.

  The ion generating elements 140a, 140b, and 140c each generate either positive ions or negative ions according to the polarity of the applied voltage. For example, the ion generating element 140a is driven to generate positive ions, the ion generating element 140b to generate negative ions, and the ion generating element 140c to generate positive ions.

  When the user holds the brush 2 with the handle 102 so that the hair 110 of the brush 2 contacts the clothing 300 as an object, the surface of the clothing 300, the hair 111, the ion generating elements 140a, 140b, 140c, The stay region 120 is surrounded by the surface of the main body 101 on which the hair 110 is planted. The deposits peeled off from the clothing 300 by the hairs 110 stay in the stay region 120. Positive ions and negative ions generated by the ion generating elements 140a, 140b, and 140c also stay in the staying region 120.

  In the staying region 120, positive ions and negative ions chemically interact on the surface of the deposit such as dust peeled off from the clothing 300 to remove the odor of the deposit. Further, the positive ions and the negative ions also chemically interact on the surface of the garment 300 to decompose odorous substances that have not adhered to the surface of the garment 300 and have not been peeled off by the hair 110, thereby reducing the odor of the garment 300. Remove.

  When an electrode that generates positive ions and an electrode that generates negative ions are arranged close to each other, the positive ions and negative ions released from the respective electrodes are likely to approach each other and neutralize and deactivate. is there. If the positive ions and the negative ions are neutralized and deactivated, the ratio of the positive ions and the negative ions used for the interaction necessary for removing odors on the surface of the object decreases.

  Since both the positive ion and the negative ion have the highest ion concentration in the vicinity of the electrode, they are most easily neutralized and deactivated in the vicinity of the electrode.

  Therefore, the ion generating elements 140a, 140b, and 140c are generated by separating the ion generating element 140a and the ion generating element 140c that generate positive ions from the ion generating element 140b that generates negative ions by the partition plate 150. It becomes difficult for high-concentration positive ions and negative ions to approach each other immediately after. In this way, the degree of neutralization deactivation due to recombination of positive ions and negative ions can be reduced.

  The ion generating elements 140 a, 140 b, and 140 c may be driven so as to generate the ions shown in the following (1) to (4) according to the charging state of the clothing 300.

(1) Generation of positive ions by the ion generation element 140a, generation of negative ions by the ion generation element 140b, generation of positive ions by the ion generation element 140c (2) generation of positive ions by the ion generation element 140a, generation of positive ions by the ion generation element 140b, Negative ion generation by ion generation element 140c (3) Negative ion generation by ion generation element 140a, positive ion generation by ion generation element 140b, negative ion generation by ion generation element 140c (4) Negative ion generation by ion generation element 140a, ion Generation of negative ions by generating element 140b and generation of positive ions by ion generating element 140c When ions are generated as in (1) to (4) above, they are generated in each of ion generating elements 140a, 140b, and 140c. When the amount of ions is equal, the ion generator 140 as a whole is not generated. The positive ions and negative ions that are generated are not the same amount. In this way, by intentionally breaking the balance of the amount of generated ions, even if the amount of ions generated in each of the ion generating elements 140a, 140b, and 140c is equal, the charge on the surface of the clothing 300 is removed. Irradiation with positive ions and negative ions can be performed.

  Furthermore, for example, the charged state of the surface of the garment 300 may be sensed in advance, and the ions generated by the ion generating element 140a and the ion generating element 140c of the brush 2 may be ions having the opposite polarity to the charging of the garment 300. . By doing so, when the user moves the brush 2 while holding the handle 102, first, ions having a polarity opposite to the charge of the garment 300 are irradiated, and the charge of the garment 300 is neutralized by the ions. Thereafter, since positive ions and negative ions are further supplied to the surface of the garment 300, the positive ions and the negative ions interact efficiently on the surface of the garment 300, and an odor removal effect is easily exhibited.

  More specifically, (1) in the case where positive ions are generated by the ion generating element 140a, negative ions by the ion generating element 140b, and positive ions by the ion generating element 140c, there is a negative ion generating electrode region in the center. There are electrodes that generate positive ions around (both sides). Therefore, in this embodiment, when the surface of the garment 300 is used in a negatively charged state, odors attached to the garment 300 can be effectively removed by oxidative decomposition. Furthermore, in this embodiment, since both regions on both sides of the negative ion generation region are regions that generate positive ions, if the brush of this embodiment is used, the brush can be moved in any direction (brushing). Since the clothes 300 are first irradiated with positive ions, the attached odor can be effectively removed.

  (2) When generating positive ions in the ion generating element 140a, positive ions in the ion generating element 140b, and negative ions in the ion generating element 140c, the positive ion generating region is larger than the negative ion generating region. Therefore, it is a form used when the clothing 300 is negatively charged. Furthermore, the polarities of the ions on both sides are different from positive ions to negative ions. Therefore, in the case of this embodiment, it is preferable to move (brush) the brush so that positive ions are first irradiated to a predetermined position of the clothing 300. Following the positive ion generation region, the positive ion generation region and the negative ion generation region continue, so that the negative charge on the surface of clothing and cloth is neutralized and deactivated by the positive ions, followed by The attached odor can be removed by the interaction between positive ions and negative ions.

  Further, (3) in the case where negative ions are generated by the ion generating element 140a, positive ions by the ion generating element 140b, and negative ions by the ion generating element 140c, there is a positive ion generating region at the center and the surroundings (both sides). There is a negative ion generation region. Therefore, in this embodiment, when the surface of the garment 300 is used in a positively charged state, the odor attached to the garment 300 can be effectively removed by oxidative decomposition. Furthermore, in this embodiment, since both regions on both sides are negative ion generating electrodes, the brush 300 of this embodiment can be negatively applied to the clothing 300 first, regardless of which direction the brush is moved (brushing). Since the ions are irradiated, the attached odor can be effectively removed.

  Finally, (4) when generating negative ions in the ion generating element 140a, negative ions in the ion generating element 140b, and positive ions in the ion generating element 140c, there are more negative ion generating areas than positive ion generating areas. Therefore, it is a form used when the garment 300 is positively charged. Furthermore, since the polarities of the ions on both sides are different from those of the positive ion generating electrode and the negative ion generating electrode, in this case, the negative ions are first irradiated to a predetermined position of clothing or cloth. It is preferable to move (brush) the brush. Since the negative ion generation region is followed by the negative ion generation region and the positive ion generation region, the positive charge of the garment 300 is neutralized and deactivated by the negative ions, and the subsequent interaction between the positive ions and the negative ions is continued. Thus, the odor attached to the clothing 300 can be removed.

  As described above, odors attached to clothes and fabrics can be effectively removed.

In the above description, the electrodes of the ion generating elements 140a, 140b, and 140c have a needle-type electrode structure, similar to the positive electrode 135 and the negative electrode 136 (FIG. 5) of the ion generating element 130. As long as ions are generated independently, a plate-type electrode or other shapes may be used.

  As described above, in the brush 2 of the second embodiment, the ion generation unit 140 includes an ion generation element for generating positive ions and an ion generation element for generating negative ions. The generating elements 140a, 140b, 140c are formed separately.

  By doing in this way, a voltage can be separately applied to ion generating element 140a, 140b, 140c, and the generation amount of a positive ion and the generation amount of a negative ion can be adjusted, respectively.

  Moreover, the brush 2 of 2nd Embodiment is provided with the partition plate 150 arrange | positioned so that a positive electrode and a negative electrode may be separated.

  By doing so, the positive ions generated at the positive electrode and the negative ions generated at the negative electrode are prevented from colliding immediately after the generation, and neutralized before reaching the residence region 120 formed by the hair 111. Thus, positive ions and negative ions that are deactivated can be reduced.

  The brush 2 may include a detection unit for detecting the charged state of the clothing 300. When the detection means for detecting the charged state of the garment 300 senses that the garment is positively charged, the amount of negative ions generated is released more than the positive ions, and the garment is negatively charged. When sensing that there is a positive ion, the amount of positive ions generated may be larger than that of negative ions and released.

  In this way, even if the garment 300 that irradiates positive ions and negative ions is positively or negatively charged, the garment 300 is charged after detecting the charged state of the garment 300 in advance. Ions can be irradiated in consideration of ion deactivation due to. By doing so, the balance between positive ions and negative ions is adjusted on the surface of the garment 300, and the effect of removing odors by the positive ions and negative ions can be maximized.

  Other configurations and effects of the brush 2 of the second embodiment are the same as those of the brush 1 of the first embodiment.

  Next, as another shape of the brush 2 of the second embodiment, a case where a plurality of electrodes for generating positive ions and a plurality of electrodes for generating negative ions are arranged respectively will be described.

  FIG. 7 is a perspective view schematically showing an entire brush of another shape of the brush according to the second embodiment.

  As shown in FIG. 7, the brush 3 is different from the brush 2 (FIG. 6) in that in the brush 3, the ion generation unit 140 includes a first ion generation unit 141 and a second ion generation unit 142. The first ion generation unit 141 and the second ion generation unit 142 are configured by a plurality of needle-type electrodes 141a and a plurality of needle-type electrodes 142a, respectively. The first ion generator 141 and the second ion generator 142 are arranged side by side. The plurality of needle-type electrodes 141a and the plurality of needle-type electrodes 142a are arranged in a plurality of rows, respectively. Further, in the brush 3, a partition plate 150 is disposed as a separating member between the first ion generation unit 141 and the second ion generation unit 142.

  The brush 3 includes a detection unit for detecting a charged state of the surface of an object such as clothing or cloth, and a control unit that controls driving of the ion generating unit 140 based on the charged state detected by the detection unit. Is provided. As a detection means, a known method can be used, and various static electricity measuring devices are sold. In these static electricity measuring devices, the charged state can be grasped by measuring the magnitude and polarity of the electric field formed when clothing or cloth is charged.

  The first ion generation unit 141 and the second ion generation unit 142 each generate positive ions or negative ions according to the polarity of the applied voltage. The first ion generation unit 141 and the second ion generation unit are configured such that the polarity of ions generated by the first ion generation unit 141 and the polarity of ions generated by the second ion generation unit 142 are reversed. A voltage is applied to 142. The first ion generation unit 141 and the second ion generation unit 142 can change the amount of ion generation independently of each other. For example, the ion generation unit 140 is controlled so that only one of the first ion generation unit 141 and the second ion generation unit 142 is increased, and the other ion generation amount is not changed. be able to.

  In order to effectively irradiate a target with positive ions and negative ions, and to irradiate positive ions and negative ions over a wider area while maintaining the concentration, a plurality of needle-type electrodes 141a and 142a are provided. It is preferable that the ion generators 140 are arranged in an array. When the brush 3 is separately provided with electrodes for generating positive ions and negative ions, it is sufficient that at least one brush exists. However, when there are a plurality of needle-type electrodes for generating positive ions and negative ions, the ion concentration can be easily adjusted, and positive ions and negative ions can be released over a wide range.

  Further, in the case where a plurality of needle-type electrodes 141a and 142a are arranged in this way, it is desirable that the partition plate 150 divides the area of the needle-type electrode that generates positive ions and the needle-type electrode that generates negative ions. .

  The reason why the partition plate 150 is provided is to prevent ions having opposite polarities from interacting with each other to be neutralized and deactivated. Since the neutralization deactivation does not occur between the needle-type electrodes that generate spilling, the partition plate 150 may not be disposed.

  The user holds the handle 102 of the brush 3, holds the brush 3 so that the hair 110 contacts the surface of the object, starts to drive the brush 3, and moves the brush in the direction indicated by the arrow P in FIG. 7. Move 3. When the brush 3 is driven, first, the detection means detects the charged state of the object. In general, when an object is formed of a chemical fiber such as polyester or acrylic, the object tends to be negatively charged. For example, when the detection unit detects that the object is negatively charged as described above, the first ion generation unit 141 disposed on the front side with respect to the moving direction P of the brush 3 The control unit controls the ion generation unit 140 so that positive ions are generated, and the second ion generation unit 142 disposed on the rear side with respect to the moving direction P of the brush 3 generates negative ions.

  Further, the control unit determines the amount of positive ions generated by the first ion generation unit 141 disposed on the front side with respect to the movement direction P of the brush 3 on the rear side with respect to the movement direction P of the brush 3. The driving of the ion generation unit 140 is controlled so as to be larger than the amount of negative ions generated by the second ion generation unit 142 disposed in the.

  To generate many ions, increase the voltage applied to the needle electrode, change the waveform of the voltage applied to the needle voltage, that is, increase the frequency or increase the number of discharges. Techniques can be used.

  Of the ions released in large quantities from the needle-type electrode, a part of the ions is used for static elimination, that is, neutralization deactivation with the surface charge of the clothing due to the surface charge of the object. And the odor adhering to a target object can be removed by interaction of the ion which was not used for static elimination, and the ion of the opposite polarity.

  In conventional air conditioners and air purifiers that generate positive ions and negative ions, a region where a plurality of needle-shaped electrodes that generate one ion (for example, positive ions) are arranged, and the other ion (for example, In many cases, the same amount of ions is generated from the region of the needle electrode that generates negative ions. This is because if the same amount of positive ions and negative ions are released into a relatively large space, the positive ions and negative ions in the space will be the same amount, and the effect of removing and inactivating viruses, fungi, and allergen components can be obtained. Because.

  However, when supplying ions to the surface of the object for the purpose of irradiating the object with ions and removing odors attached to the surface of the object, supply the same amount of positive ions and negative ions. However, the balance between positive ions and negative ions may be lost depending on the charged state of the surface of the first object. As a result, the degree of interaction between positive ions and negative ions decreases, and odors attached to the object may not be sufficiently removed. For example, when the surface of an object is negatively charged (in the case of chemical fibers), even if the same amount of positive ions and negative ions are irradiated, the positive ions are neutralized and deactivated compared to the negative ions. The ratio which ends up increases. If this is the case, the concentration of positive ions on the surface of the object will be less than the concentration of negative ions, so the degree of interaction between positive ions and negative ions will decrease, and the removal characteristics of attached odor will decrease. May end up. Therefore, assuming positive neutralization deactivation on the surface of the object, the positive ion concentration is increased and released in advance. By doing so, positive ions are reduced due to neutralization inactivation, but odors adhering to clothing and fabric surfaces are effectively removed by oxidative decomposition due to the interaction between the remaining positive ions and negative ions. Can do.

  Conversely, when the surface of the object is positively charged, negative ions are generated by the first ion generation unit 141, positive ions are generated by the second ion generation unit 142, and negative ions are generated. The driving of the ion generator 140 is controlled so as to generate a large amount.

  Other configurations and effects of the brush 3 are the same as those of the brush 2.

  As described above, when the brush 6 includes the propeller fan 160, positive ions and negative ions can efficiently reach the staying region 120 formed on the surface of the garment 300.

  Other configurations and effects of the brush 6 are the same as those of the brush 2.

(Third embodiment)

It is a bottom view (C) when the brush shown to (B) and FIG. In FIG. 11B, illustration of the hair planted on the handle side with respect to the ion generating element is omitted.

  As shown in FIG. 11, the brush 7 of the third embodiment is different from the brush 2 of the second embodiment in that the ion generator 140 of the brush 7 has a plurality of ion winds that can generate an ion wind. The generating element 145 is configured. The ion wind generating element 145 includes a housing 145c, a needle electrode 145a, and a counter electrode 145b.

  FIG. 12 is a diagram schematically showing an entire ion wind generating element provided in the brush according to the third embodiment.

  As shown in FIG. 12, the ion wind generating element 145 includes a housing 145c, a needle electrode 145a disposed inside the housing 145c, and a mesh-like facing disposed so as to face the tip of the needle electrode 145a. It comprises an electrode 145b and driving means 145d. The needle electrode 145a and the mesh-like counter electrode 145b are fixed to a jig. Although FIG. 12 shows a state in which a plurality of needle-type electrodes 145a are arranged, a plurality of needle-type electrodes 145a may be provided or one. By arranging a plurality of needle-type electrodes 145a, the air volume can be increased, and the characteristics as a blower can be improved.

  Here, the ion wind generating element 145 will be described.

  In general, as an air blowing means, an air blowing device that attracts an air flow and uses the air flow is used in various regions. However, these blowers often use a blower fan and a driving motor in combination.

  On the other hand, in recent years, a blower using an ionic wind generated by a discharge phenomenon has attracted much attention. In an air blower using ion wind, instead of generating air flow by mechanical energy, charged particles are directly accelerated in the air, and the air flow is generated by the interaction between ions and air molecules. generate. By such a non-mechanical method, a highly efficient blower can be achieved in principle.

  In such an ion wind blower, since the shape of the needle electrode and the counter electrode arranged opposite to the needle electrode is remarkably different, the electric field generated when a voltage is applied between these electrodes An ionic wind is generated when the state becomes significantly distorted. As a result, the electric field strength in the vicinity of the tip of the needle electrode is maximized, and atmospheric ions generated at the tip of the needle electrode are accelerated by the electric field. And neutral particles move together to generate wind flow.

  In the ion wind blowing device, it is effective to increase the electric field strength in order to obtain good blowing characteristics. Therefore, the blower using the needle-type electrode exhibits the most excellent characteristics. Since the tip of the needle electrode has a sharp shape with a tip radius of 60 microns, for example, the electric field strength in the vicinity of the tip can be increased.

  For example, when electrodes having the same shape (two parallel plate electrodes) are used for the needle-type electrode and the counter electrode as electrodes having a completely different shape from the ion wind generating element 145 shown in FIG. 12, the distance between the plates is set to 5 mm. When a voltage of 3 kV is applied, the electric field strength in the vicinity of the electrode becomes a small value of 3 kV / 5 mm = 0.6 kV / mm. With such a small electric field strength, no discharge phenomenon occurs and no ionic wind is generated.

  On the other hand, it is known from the electric field strength simulation analysis that when a sharp needle-shaped electrode having an extremely small tip radius of 2 micrometers is used as the discharge phenomenon generating electrode, an extremely strong electric field of 300 kV / mm or more is formed. By forming an extremely strong electric field in this way, a discharge phenomenon occurs, and ions generated by the strong electric field in the vicinity of the needle-type electrode are accelerated, thereby obtaining air blowing.

  When a DC voltage or AC voltage is applied between the needle electrode and the counter electrode, the shape of the electrode is significantly different from that of the needle electrode and the counter electrode. A discharge phenomenon in the state of an unequal electric field that becomes equal, for example, a corona discharge phenomenon occurs. Thereby, ions are released from the tip of the needle electrode toward the counter electrode. Note that the polarity of ions generated from the needle electrode is the same as the polarity of the needle electrode. That is, when the needle electrode is positive, positive ions are released, and when the needle electrode is negative, negative ions are released.

  Next, the generated ions are released from the tip of the needle electrode by an electric field generated between the needle electrode and the counter electrode, and are accelerated toward the counter electrode. At this time, in order to frequently collide with many neutral molecules and neutral particles existing between the needle-type electrode and the counter electrode, not only ions but also these neutral particles gradually and in the same direction as the ions. Then, it starts to move from the needle-shaped electrode toward the counter electrode, and an air flow is generated as a whole. This becomes the above-described ion wind, and the ion wind blower functions as a blower mechanism.

  Furthermore, when ion wind is used for the air blowing method, ions are released from the needle-type electrode due to a discharge phenomenon. That is, in the case where ion wind is used as the air blowing method, it is possible to release ions into the space simultaneously with the flow of the air flow.

  FIG. 13 is a diagram showing the amount of ions generated when the counter electrode is GMD and a DC positive voltage or negative voltage is applied to the needle electrode in the ion wind generating element shown in FIG.

  As shown in FIG. 13, the ion concentration increases with a positive correlation with the magnitude of the applied voltage. The ion wind generating element 145 shown in FIG. 12 can generate a flow of an air current for generating ions and a flow of air to discharge the ions into the space. Space saving and weight reduction can be achieved as compared with the case where the air blowing means is provided.

  As described above, in the brush 7 of the third embodiment, the ion generator 140 includes the ion wind generating element 145 that generates the ion wind.

  By doing in this way, positive ions and negative ions can efficiently reach the staying region 120 formed on the surface of the garment 300. Further, since the wind can be generated without providing a blowing means such as a propeller fan or a cross flow fan, it is possible to provide the brush 7 capable of saving space and reducing power consumption.

  Other configurations and effects of the brush 7 of the third embodiment are the same as those of the brush of the first embodiment.

(Fourth embodiment)
FIG. 14 is a diagram schematically showing the entire brush as a fourth embodiment of the present invention.

  As shown in FIG. 14, the brush 8 of the fourth embodiment is different from the brush 4 of the second embodiment in that the first ion generator 141 and the second ion generator are generated according to the moving direction of the brush. A switching unit 180 for changing the polarity of ions generated by the unit 142 and the third ion generation unit 143, and a polarity detection unit 170 for detecting the charging polarity of an object such as clothing or cloth. The brush 8 includes a control unit 200 for controlling the driving of the ion generation unit 140, a drive circuit 201 for the first ion generation unit 141, a drive circuit 202 for the second ion generation unit 142, and a third unit. The drive circuit 203 of the ion generator 143 is provided. In FIG. 14, the control unit 200 and the drive circuits 201, 202, and 203 are drawn outside the brush 8, but the control unit 200 and the drive circuits 201, 202, and 203 are accommodated inside the brush 8. ing.

  The control unit 200 receives a signal from the polarity detection unit 170, and the control unit 200 drives the drive circuit 201 of the first ion generation unit 141, the drive circuit 202 of the second ion generation unit 142, and the third ion. A control signal is transmitted to the drive circuit 203 of the generation unit 143. The polarity detection unit 170 detects the polarity of charge on the surface of an object such as clothing or cloth that the brush 8 contacts, and transmits a signal to the control unit 200.

  FIG. 15 is a diagram schematically illustrating a configuration of a moving direction detection unit included in the brush according to the fourth embodiment.

  As shown in FIG. 15, the switch unit 180 includes first switches 181a and 181b, second switches 182a and 182b, and cams 183a and 183b.

  As shown in FIG. 15A, when the brush 8 (FIG. 14) is not moved, the cam 183a and the cam 183b are connected to both the first switch 181a and 181b and the second switch 182a and 182b. Do not touch.

  As shown in FIG. 15B, when the brush 8 is moved in the direction indicated by the arrow P1, the tips of the cams 183a and 183b are inclined in the direction of the arrow Q1 with respect to the roots of the cams 183a and 183b. When the tips of the cams 183a and 183b are tilted in the direction of the arrow Q1, the cam 183a contacts the second switch 182a, and the cam 183b contacts the second switch 182b.

  As shown in FIG. 15C, when the brush 8 is moved in the direction indicated by the arrow P2, the tips of the cams 183a and 183b are inclined in the direction of the arrow Q2 with respect to the roots of the cams 183a and 183b. When the tips of the cams 183a and 183b are tilted in the direction of the arrow Q2, the cam 183a contacts the first switch 181a, and the cam 183b contacts the first switch 181b.

  The first switch 181a and the second switch 182a constitute a part of the drive circuit 201 of the first ion generation unit 141, and the first ion generation is performed by switching the switch with which the cam 183a contacts. The polarity of ions generated in the unit 141 is switched.

  Further, the first switch 181b and the second switch 182b constitute a part of the drive circuit 203 of the third ion generator 143, and the second contact is switched by switching the switch that the cam 183b contacts. The polarity of ions generated by the ion generator 142 is switched.

  Thus, by moving the brush to the right or left, the contact point with the electrode for generating positive ions or negative ions is mechanically switched, and the polarity of the generated ions is switched depending on the moving direction of the brush.

  The polarity of ions generated by the ion generator 140 when the brush 8 is moved along the surface of the object will be described with reference to FIGS. 14 and 15.

  When the brush 8 is moved along the surface of the object in the direction of the arrow P1, the cams 183a and 183b are in contact with the first switches 181a and 181b in the switch unit 180. The polarity detection unit 170 detects the polarity of charging on the surface of the object and transmits a signal to the control unit 200. The control unit 200 generates the first ions arranged on the front side with respect to the movement direction P1 so as to generate ions having a polarity opposite to the charged polarity of the surface of the object detected by the polarity detection unit 170. The drive circuit 201 of the unit 141 is controlled.

  When the brush 8 is moved in the direction indicated by the arrow P1, the first ion generator 141 serves as a static elimination ion generator.

  In addition, as described for the brush 2 of the second embodiment, the control unit 200 generates positive ions or negative ions from the second ion generation unit 142 and the third ion generation unit 143, so that the drive circuit 202 is generated. , 203 are controlled.

  In the present embodiment, for example, when the first ion generator 141 generates negative ions when the brush 8 is moved in the direction of the arrow P1, the second ion generator 142 generates negative ions, In the third ion generation unit 143, the control unit 200 controls the drive circuits 201, 202, and 203 so as to generate positive ions. When the brush 8 is moved in the direction of the arrow P1, when the first ion generation unit 141 generates positive ions, the second ion generation unit 142 generates positive ions and the third ion generation unit 143. Then, the control unit 200 controls the drive circuits 201, 202, and 203 so as to generate negative ions.

  When the moving direction of the brush 8 is changed from the direction indicated by the arrow P1 to the direction indicated by the arrow P2, the cams 183a and 183b rotate in the direction indicated by the arrow Q2 and come into contact with the second switches 182a and 182b.

  When the switch in contact with the cams 183a and 183b is switched, the polarity of the ions generated in the first ion generation unit 141 and the third ion generation unit 143 is moved in the direction of the arrow P1. The drive circuits 201 and 203 are controlled so as to be opposite to the polarity of the ions generated in the current.

  When the brush 8 is moved in the direction indicated by the arrow P2, the second ion generator 142 serves as a static elimination ion generator.

  For example, when the brush 8 is moved in the direction of the arrow P1, negative ions are generated by the first ion generation unit 141 and positive ions are generated by the third ion generation unit 143. When the movement direction is changed so as to move in the direction of P2, negative ions are generated in the third ion generation unit 143 on the front side with respect to the movement direction P2, and positive ions are generated in the first ion generation unit 141. Ions will be generated. In the 2nd ion generation part 142, the ion of the same polarity as the ion generated in the 3rd ion generation part 143 arrange | positioned ahead with respect to the moving direction P2 is generated.

  In this way, by combining mechanical means such as a cam and a microswitch with the brush, the polarity of ions to be generated can be changed by a simple method.

  Further, when an object such as clothing or cloth is charged, it is generated in the first ion generation unit 141, the second ion generation unit 142, and the third ion generation unit 143 according to the direction in which the brush moves. Even if the movement direction of the brush is changed by switching the polarity of the ion to be generated, ions with a polarity that neutralizes the charging of clothes and fabrics are arranged on the front side with respect to the movement direction of the brush Can be generated in parts.

  In this way, after first removing the charge of an object such as clothing or cloth, the odor attached to the clothing can be effectively removed by utilizing the interaction between positive ions and negative ions.

  On the surface of clothing and cloth, when the number of positive ions and negative ions is the same in a balanced manner, the effect of removing odors by positive ions and negative ions is best exhibited. For this reason, when the brush 8 is applied to clothing or cloth, the charge of clothing such as clothing or cloth is first neutralized by irradiating ions with the opposite polarity to the initial charge of clothing or cloth. To do. In this way, after the clothes are first neutralized, by irradiating positive ions and negative ions in a balanced manner, these positive ions and negative ions are irradiated in a balanced manner, and most effectively, Odors attached to objects such as clothing and cloth can be removed.

  As described above, the brush 8 according to the fourth embodiment includes the polarity detection unit 170 for detecting the polarity of the charge on the surface of the garment, and the ion generation unit 140 has the brush 8 relative to the surface of the garment. A static elimination ion generator disposed on the front side of the brush 8 relative to the clothing, and the static ion detector 170 detects the static elimination ion generator. It generates ions with the opposite polarity to the polarity of the charge on the clothing surface.

  The polarity detection unit 170 detects the polarity of the charge on the surface of the garment in advance, and the ion removal ion generator disposed on the front side of the ion generation unit 140 generates ions having a polarity opposite to the polarity of the charge on the surface of the garment. Thus, first, the charge on the surface of the clothing can be neutralized with ions generated in the static elimination ion generator. When the charge on the surface of the garment is neutralized by the ions generated in the static elimination ion generator, the surface of the garment is in a neutralized state. Thereafter, positive ions and negative ions generated by the ion generator 140 are retained in a retention region 120 formed on the surface of the clothing.

  By doing in this way, the deodorizing effect by a positive ion and a negative ion can be heightened.

  Other configurations and effects of the brush 8 of the fourth embodiment are the same as those of the brush 4 of the second embodiment.

(Fifth embodiment)
16 is a front view (A) showing the entire brush as a fifth embodiment of the present invention, and a sectional view when the brush shown in FIG. 16 (A) is viewed from the direction indicated by the line BB. It is a bottom view (C) when the brush shown to B) and the brush shown to (A) of FIG. In FIG. 16B, illustration of the hair planted on the handle side with respect to the ion generating element is omitted.

  As shown in FIG. 16, the brush 9 of the fifth embodiment is different from the brush 6 of the second embodiment in that the brush 9 includes a piezoelectric element 190 as a contact detection unit. The piezoelectric element 190 is provided on the main body 101 in which the hair 110 formed of fibrous animal hair, plant hair, or resin hair is planted.

  When the hair 110 contacts the surface of the garment 300, the piezoelectric element 190 detects this contact. When the piezoelectric element 190 detects contact of the hair 110 with the surface of the garment 300, the ion generator 140 is energized and the drive of the ion generator 140 is started. That is, the hair 110 also serves as a drive switch for the ion generator 140.

  In addition to the piezoelectric element 190, the contact detection unit may be, for example, a structure in which electrodes are provided on the back and body of the brush, a switch using resistance change of conductive rubber, a piezoelectric sensor, or the like. The contact detection unit is a means for detecting pressure because force is applied to the contact between the hair 110 and the main body 101 when the hair 110 comes into contact with the surface of the clothing 300, so that the hair 110 contacts the clothing 300. It is possible to determine whether or not a physical action is given.

  In addition, the piezoelectric element 190 may directly switch ON / OFF of the power supply of the ion generation unit 140, or may switch ON / OFF of the power supply of the ion generation unit 140 via a control unit. There may be, and it is not limited to the method of this embodiment.

  In addition, when the propeller fan 160 is attached as a blowing means, in addition to controlling the operation of the ion generator 140, the propeller fan 160 for irradiating the cloth with ions is also controlled by driving and stopping the driving. By performing simultaneously with the element 190, further power saving can be achieved.

  In the brush 9 of the present invention, the ion generating elements 140a, 140b, and 140c of the ion generating unit 140 are operated to irradiate ions in order to remove odor attached to the clothing 300 as an object. Therefore, when the ion generating elements 140a, 140b, and 140c are driven, power is consumed.

  Since the brush of the present invention consumes electric power, it is desirable to make the power consumption as low as possible. Therefore, it is preferable to reduce the time during which the ion generating element is energized and operated by a simple method as much as possible.

  As described above, the brush 9 according to the fifth embodiment includes the piezoelectric element 190 for detecting that the bristles 110 are in contact with the surface of the garment 300, and the ion generation unit 140 includes the bristles 110 having the bristles 110 of the garment 300. Ions are generated when the piezoelectric element 190 detects contact with the surface.

  By doing in this way, power consumption can be suppressed.

  Other configurations and effects of the brush 9 of the fifth embodiment are the same as those of the brush 6 of the second embodiment.

  The brush 9 includes the propeller fan 160, but may not include the propeller fan 160.

  In the first to fifth embodiments, the stay region 120 is surrounded by the hair 111 that is a part of the hair 110, but the stay region 120 is not necessarily formed by being surrounded by the hair 111. It is not necessary to form at least positive ions, negative ions, and adhering substances.

  As one effect of the deposit removing tool according to the present invention, there is an effect of effectively removing the odor of the object by the physical action of the deposit peeling member and the chemical action of positive ions and negative ions. is there. In order to confirm this effect, the sensory evaluation test by the 6-step odor intensity | strength display method by the six panelists was done about the test cloth which adhered the tobacco odor.

  After attaching the odor of tobacco to the test cloth (polyester cloth), the test cloth was blown. The test cloth was blown under the following conditions (1) to (4).

  (1) Do not irradiate ions and do not brush the test cloth.

(2) Irradiate the test cloth with H ⁺ (H ₂ O) _m (m is a natural number) as positive ions generated from the ion generating element and O ₂ ⁻ (H ₂ O) _n (n is a natural number) as negative ions. However, do not brush the test cloth.

  (3) Brush the test cloth without irradiating with ions.

(4) The test cloth is irradiated with H ⁺ (H ₂ O) _m (m is a natural number) as positive ions generated from the ion generating element and O ₂ ⁻ (H ₂ O) _n (n is a natural number) as negative ions. Then, brush the test cloth.

The blower was operated for 30 minutes under the conditions (1) to (4). After blowing air under each condition, the odors of the test cloths were compared by a sensory test using a six-step odor intensity display method. When the test cloth was irradiated with ions, the ion concentration was 10000 ions / cm ^{3 for} each of positive ions and negative ions, and the irradiation time for irradiation with ions was 30 minutes.

  Table 2 is a table | surface which shows the result of the sensory test by a 6-step odor intensity display method about said test cloth.

As shown in Table 2, immediately after the cigarette odor was adhered, the odor intensity of the test cloth was 4.8. When this test cloth was blown only for 30 minutes without irradiating with ions and without brushing, the odor intensity was 4.2. On the other hand, when a test cloth having an odor intensity of 4.8 was blown while irradiating positive ions and negative ions with an ion concentration of 10,000 ions / cm ³ for 30 minutes without brushing, the odor intensity was 4.0. Thus, it was found that the odor intensity was reduced by the action of ions.

On the other hand, when the test cloth having an odor intensity of 4.8 was not irradiated with ions, but only brushing was performed, the odor intensity was 4.1. Further, when a test cloth having an odor intensity of 4.8 is irradiated with positive ions and negative ions having an ion concentration of 10,000 ions / cm ³ for 30 minutes and blown while brushing, the odor intensity becomes 3.8. It was. Thus, it turned out that odor intensity | strength is reduced by brushing.

  FIG. 17 is a diagram showing the effect of odor removal by ion and brushing.

  As shown in FIG. 17, (1) when no ion irradiation was performed and no brushing was performed, the odor intensity was 4.2, but (2) when no ion brushing was performed and ions were irradiated. The odor intensity became 4.0. When (1) and (2) were compared without brushing, it was found that the effect of removing odors by ion irradiation was an effect of reducing the odor intensity by 0.2.

  On the other hand, (3) when brushing is performed without irradiating ions, the odor intensity is 4.1. (4) when brushing is performed while irradiating ions, the odor intensity is 3 .8. When (3) and (4) are compared when brushing is performed, it can be seen that the effect of removing odors by ion irradiation was an effect of reducing the odor intensity by 0.3.

  If, in the brush as the deposit removing tool of the present invention, the effect of chemical odor removal by ion irradiation and the effect of physical odor removal by brushing are simply added, (4) The odor intensity when brushing is performed while irradiating ions is (3) 3.9, which is 0.2 lower than the odor intensity 4.1 when not irradiating ions and performing brushing. Should be.

  However, as described above, (4) when brushing was performed while irradiating ions, the odor intensity was 3.8, which is 0.1 lower than 3.9.

  Thus, it was found that the effect of removing odors by irradiating ions can be enhanced by irradiating ions while brushing.

  Using the brush 6 (FIG. 10) of the second embodiment, an experiment was conducted to confirm the effect of removing odors.

  As the main body of the brush 6 (FIG. 10), resin (acrylic resin processing) was used as in the conventional brush. However, in order to form means for irradiating ions on the surface of clothing or cloth, an acrylic hollow structure was used. Further, conventionally used brush bristles were diverted to the fibrous bristles 110 for applying physical action to remove dust.

  The ion generating element 130 shown in FIG. 5 is disposed in the ion generating section 140 (FIG. 10).

  As the blowing means, a conventionally known propeller fan (DC axial flow fan manufactured by Nippon Servo Co., Ltd.) was used. The wind speed was set to 0.10 m / sec so that ions were effectively irradiated. For measurement of the wind speed, a thermal anemometer (model number: 6543) manufactured by Nippon Kanomax Co., Ltd. was used. The measurement principle is a known method, but the following method is used. That is, the wind speed measuring sensor unit is overheated, and when the sensor unit is exposed to wind, the heat is removed and the temperature of the sensor unit changes. In order to compensate for this temperature change, the amount of current to be energized is changed, and the wind speed is calculated from this amount of current.

The ion concentration generated in the ion generation unit 140 was an environment with an extremely high concentration of 1.5 million ions / cm ³ or more for both positive ions and negative ions. Therefore, it was confirmed that the ion concentration was sufficient to exert the removal characteristic against odors attached by conventional ions.

  All these measurements were performed in a general space.

  The polyester cloth to which the odor of tobacco was attached was irradiated with ions using the brush 6 of the present invention. The irradiation time was 30 minutes in this test. For comparison, the same evaluation was performed when only the blowing means was operated without operating the ion generating element.

  The odor intensity by the 6-step odor intensity display method of the polyester cloth to which the odor of tobacco was attached was as follows. That is, in the polyester cloth immediately after the odor adheres to the tobacco, the odor intensity is 4.0, and in the polyester cloth after irradiation with ions for 30 minutes, the odor intensity is 2.8, after blowing for 30 minutes without operating the ion generating element. In the polyester cloth, the odor intensity was 3.3.

  Thus, the removal of the odor adhering to the polyester cloth was able to be confirmed by irradiating ion using the brush 6 of 2nd Embodiment.

  The following experiment was conducted in order to confirm the effect of odor removal using the brush 7 (FIG. 11) of the third embodiment.

  In Example 3, an ion wind generating element was used as the blowing means. Other conditions were the same as in Example 2.

  As the ion wind generating element (needle electrode) of the ion wind generating element, a metal needle having a tip radius of 2 microns was used. As the material of the needle electrode, tungsten having a high resistance to the discharge phenomenon was used. The length of the metal needle used for the needle electrode was 20 mm and the diameter was 0.5 mm. For a cylindrical tungsten needle having a diameter of 0.5 mm, a 5 mm portion at the tip of a length of 20 mm was processed by an electropolishing method. In order to use the needles produced by this electropolishing method as needle-type electrodes, 10 were arranged.

  Of the 10 needle-type electrodes, 5 are applied with a positive DC voltage to generate positive ions, and the other 5 are applied with a negative DC voltage to generate negative ions. Form.

  As a driving power source for the ion wind generating element, a direct current voltage of a positive voltage was applied to the needle type electrode as a voltage application method between the needle type electrode and the counter electrode. A DC high voltage power supply (model number: HJPQ-10P3) manufactured by Matsusada Precision Co., Ltd. was used as a power supply for applying a positive voltage. A DC high voltage power supply (model number: HJPQ-10M3) manufactured by Matsusada Precision Co., Ltd. was used as a power supply for applying a positive voltage.

The magnitude of the applied voltage was set to 3.8 kV when a positive voltage was applied so that the wind speed was 3 m / sec. The ion concentration generated at this time was an extremely high concentration environment of 2 million ions / cm ³ or more for both positive ions and negative ions. Therefore, it was confirmed that the ion concentration was sufficient to exert the removal characteristic against odors attached by conventional ions.

  All these measurements were performed in a general space.

  The polyester cloth to which the odor of tobacco was attached was irradiated with ions using the brush 7 of the present invention. The irradiation time was 30 minutes in this test. For comparison, the same evaluation was performed when only the blowing means was operated without operating the ion generating element.

  The odor intensity by the 6-step odor intensity display method of the polyester cloth to which the odor of tobacco was attached was as follows. That is, in the polyester cloth immediately after the odor adheres to the tobacco, the odor intensity is 4.0, and in the polyester cloth after irradiation with ions for 30 minutes, the odor intensity is 3.0, and the air is blown for 30 minutes without operating the ion generating element. In the later polyester cloth, the odor intensity was 3.6.

  Thus, the removal of the odor adhering to the polyester cloth was able to be confirmed by irradiating ion using the brush 7 of 3rd Embodiment.

  Using the brush 9 (FIG. 16) of the fifth embodiment, the same experiment as in Example 2 was performed in order to confirm the effect of removing odors.

  The odor intensity by the 6-step odor intensity display method of the polyester cloth to which the odor of tobacco was attached was as follows. That is, in the polyester cloth immediately after the odor adheres to the tobacco, the odor intensity is 4.0, and in the polyester cloth after irradiation with ions for 30 minutes, the odor intensity is 2.8, and the air is blown for 30 minutes without operating the ion generating element. In the later polyester cloth, the odor intensity was 3.3.

  Thus, the removal of the odor adhering to the polyester cloth was able to be confirmed by irradiating ion using the brush 9 of 5th Embodiment.
