Description

  The present invention relates to an air purifier that removes fine particles floating in the air, and more particularly to an air purifier having a simple structure and a deodorizing function.

  In recent years, with the progress of aging and lifestyle-related diseases, other people aim at facilities where many people gather, such as schools, hospitals, theaters, restaurants and pachinko parlors, for the purpose of health management in addition to improving nutrition. Legal regulations, such as requiring measures to prevent "passive smoking" where smoke from cigarettes are smoked, are being strengthened.

  As a measure to prevent passive smoking, it is good to install an air purifier in the room, but the basic structure of the air purifier is to convert the indoor air taken in by the fan drive into an air filter made of fiber membrane or activated carbon. Since this is discharged into the room, relatively large suspended particles can be captured by the air filter, but it is very difficult to capture tobacco smoke.

  Even if the smoke particles can be trapped, dirty air is repeatedly passed through the air filter, so it is necessary to replace it in a short period of time, and the odor components adhering to the filter get on the air flow. There is a difficulty in spreading indoors.

  Then, the air cleaner provided with the deodorizer which incorporates the cartridge containing deodorizers, such as a liquid and a jelly form, is proposed (for example, patent document 1).

Japanese Utility Model Publication No. 7-32429

  However, even with an air cleaner as disclosed in Patent Document 1, the deodorizing effect by the deodorant is lost early. For this reason, the deodorant cartridge has to be replaced in a short period of time, and there is a disadvantage that running cost increases.

  Also, there are deodorizers that remove unpleasant odors by chemical action or physical adsorption action and those that suppress unpleasant odors, but those that use chemical action have safety problems, Those using the physical adsorption action have a problem in the sustainability of the deodorizing effect. Moreover, since the thing which suppresses an unpleasant odor is mainly masking with an aromatic substance, an unpleasant odor cannot be cut off from the origin.

  The present invention has been made in view of the above circumstances, and its purpose is to eliminate unpleasant odors caused by cigarette smoke without using harmful chemical substances or ozone at all. An object of the present invention is to provide an air purifier having a deodorizing function that exhibits an excellent deodorizing effect.

  In order to achieve the above object, the present invention provides a fan inside a housing having a suction port and a blower outlet, and an air filter is provided in the flow path of air flowing from the suction port to the blower outlet by driving the fan. In the air purifier arranged, a structure in which different substances are accommodated in contact with each other in a container having a predetermined shape is disposed in the air flow path in the housing.

  In the air purifier as described above, the different kinds of substances are two kinds of metals, or granular ore and ceramic, and further, a negative ion generator and an ultraviolet radiation device are installed in the air flow path in the enclosure. It is characterized by being arranged.

  According to the present invention, a fan is provided inside a housing having a suction port and a blower outlet, and an air filter is disposed in a flow path of air flowing from the suction port toward the blower outlet by driving of the fan. In an air cleaner, a structure in which different kinds of materials such as two kinds of metals, granular ores and ceramics are accommodated in a container having a predetermined shape is arranged in a flow path of air in the housing. As a result, a weak current can be generated based on the contact potential difference between different substances while trapping suspended substances in the air by the action of the air filter, and this can be directly applied to the air.

  Thereby, the cluster in the air which flows toward a blower outlet from a suction inlet can be destroyed, and malodors, such as tobacco smoke, can be erased.

  In addition, since a negative ion generator is arranged in the air flow path in the housing, the deodorizing effect is further improved by the negative ions generated by this, and the synergistic effect with the structure described above causes the action of negative ions. Is effective.

  Furthermore, since the ultraviolet radiation device is disposed in the air flow path in the housing, it is possible to kill mites and pathogens contained in the air and generate clean air.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic perspective view showing an air cleaner according to the present invention. In FIG. 1, reference numeral 1 denotes a housing of the apparatus. A slit-like suction port 2 is formed on the front surface of the lower portion, and an opening 3 for arranging an air filter to be described later on the back side of the suction port 2 is formed on the lower side surface. Provided. A slit-shaped air outlet 4 is formed on the upper front surface and both side surfaces of the housing 1.

  In this example, although the suction inlet 2 and the blower outlet 4 are only the hole which cut off the housing 1 partially, a louver can be provided in the blower outlet 4 and adjustment of a wind direction can also be made possible. In FIG. 1, 5 is an electric cord for obtaining drive power from an external power source, and 6 is a main power switch arranged on the front surface of the housing.

  Next, FIG. 2 is a sectional view showing the internal structure of the air cleaner. As is apparent from this figure, the inside of the housing 1 is divided into a lower region 8 having a suction port 2 and an upper region 9 having a blower port 4 by a partition plate 7. A flow path for flowing air from the mouth 2 toward the outlet 4 is formed.

  The partition plate 7 has a vent 10 that allows air to flow from the lower region 8 to the upper region 9, and a fan 11 that faces the vent 10 on the upper region 9 side is attached to the partition plate 7. Then, the fan 11 is driven by obtaining power from the outside by operating the main power switch 6 shown in FIG. 1, and external air is taken into the housing 1 from the suction port 2 by the driving, and this is the lower region. The air circulation in which the air is discharged from the air outlet 4 to the outside through the upper region 9 from 8 is repeated.

  Here, 12 is the above-described air filter, and the air filter 12 has a structure in which a fiber membrane having a predetermined air permeability is held by a frame. As described above, the air filter 12 is disposed on the back side of the suction port 2. For this reason, the air sucked into the housing 1 passes through the air filter 12 to remove relatively large suspended particles such as dust. The In addition, as the air filter 12, a case in which a porous substance such as activated carbon is accommodated in a case having air permeability can be used.

  As is clear from FIG. 2, a negative ion generator 13 is provided in the housing 1. This negative ion generator 13 is a well-known one composed of a voltage generator 13A having a piezoelectric transformer and the like, a needle-like discharge electrode 13B, and the like, and applies a high voltage obtained by the voltage generator 13A to the discharge electrode 13B. Then, negative ions are generated by corona discharge. Then, according to the negative ion generator 13, the negative ions are disposed in the upper region 9 on the downstream side of the fan 11 and diffused into the air sent out from the fan 11, thereby the malodorous component contained in the air is removed. Works to break down.

  On the other hand, 14 is a known ultraviolet radiation device, which includes a device body having a light source such as a mercury lamp, a discharge tube such as hydrogen or a rare gas, a quartz lamp, or an arc lamp, and a drive circuit for lighting the light source. Consists of The ultraviolet radiation device 14 is attached in the lower region 8 and functions to kill mites and pathogens contained in the air taken into the housing 1.

  Further, the lower region 8 is provided with a structure 15 that emits a negative ion beam. Such a structure 15 is formed by accommodating different kinds of substances in contact with each other in a container 16 having a predetermined shape, and is fixed in an upright state directly below the fan 11 by a U-shaped metal fitting 17.

  The structure of the structure 15 will be described in detail with reference to FIG. 3. In this example, the container 16 includes a cylindrical container body 16A and caps 16B that close both ends thereof. The container body 16A and the cap 16B are made of a metal such as stainless steel or an aluminum alloy (Al-Mn alloy, Al-Si alloy, Al-Mg alloy, Al-Mg-Si alloy, Al-Zn-Mg alloy). In the container 16, granular ore Ma and ceramic Mb are accommodated as different substances. In particular, ceramic Mb is accommodated on both sides of the container body 16A, and ore Ma is accommodated therebetween. Note that the ore Ma may be accommodated on one end side of the container body 16A and the ceramic Mb may be accommodated on the other end side.

  Here, as the ore Ma, for example, plutonic rocks having an equigranular structure such as gabbro, diorite, and syenite, preferably granite (granite), which is a kind thereof.

Examples of the ceramic Mb include glass ceramics (Li ₂ O—Al ₂ O ₃ —SiO ₂ type, MgO—Al ₂ O ₃ —SiO ₂ type, PbO—ZnO—B ₂ O ₃ type, SiO ₂ —Al _{2 type. O 3 -CaO-ZnO-BaO-} Na 2 O -based) is used.

  And according to the structure 15 comprised as mentioned above, the malodorous component contained in the tobacco smoke etc. is removed from the air taken in in the housing 1, and the negative ion generated from the negative ion generator 13 and In combination, the deodorizing effect can be maintained over a long period of time. The cause is not necessarily clear so far, but a weak electric current is generated due to a contact electric phenomenon (Volta effect) based on a potential difference due to contact between different kinds of materials (in this example, the ore Ma and the ceramic Mb). It is considered that an ion beam (photon) is radiated to the outside, which acts directly on the surrounding air and destroys a cluster of malodorous components contained in the air.

  The dissimilar materials are not limited to the granular ore Ma and ceramic Mb as described above, and two kinds of metals Mc and Md can also be used. The dissimilar metals Mc and Md may be in the form of a lump or plate, but it is preferable to form a plate having a large contact area as shown in FIG.

  In addition, various combinations of such different metals Mc and Md are conceivable. As combinations thereof, titanium and copper, copper and tin, copper and nickel, copper and iron, copper and magnesium, copper and zinc, copper and lead, copper And gold, copper and silver, copper and platinum, copper and palladium, copper and cobalt, tin and titanium, tin and nickel, tin and iron, tin and magnesium, tin and zinc, tin and lead, tin and gold, tin and silver , Tin and platinum, tin and palladium, tin and cobalt, nickel and titanium, nickel and iron, nickel and magnesium, nickel and zinc, nickel and lead, nickel and gold, nickel and silver, nickel and platinum, nickel and palladium, nickel And cobalt, iron and titanium, iron and magnesium, iron and zinc, iron and lead, iron and gold, iron and silver, iron and platinum, iron and palladium, iron and cobalt, magnesium and titanium, magnesium and zinc, magne Um and lead, magnesium and gold, magnesium and silver, magnesium and platinum, magnesium and palladium, magnesium and cobalt, zinc and titanium, zinc and lead, zinc and gold, zinc and silver, zinc and platinum, zinc and palladium, zinc and Cobalt, lead and titanium, lead and gold, lead and silver, lead and platinum, lead and palladium, lead and cobalt, gold and titanium, gold and silver, gold and platinum, gold and palladium, gold and cobalt, silver and titanium, Silver and platinum, silver and palladium, silver and cobalt, platinum and titanium, platinum and palladium, platinum and cobalt, palladium and titanium, palladium and cobalt, titanium and cobalt, and the like are conceivable.

  Even if such a dissimilar metal is accommodated in a container in a contact state, a large amount of negative ion beams can be generated to deodorize the air.

  Incidentally, it is also known to increase ubiquinol, which is a kind of antioxidant that detoxifies active oxygen in the body, as an action of negative ions.

  Although the present invention has been described above, the container 16 constituting the structure 15 is not limited to a cylindrical shape, and may be a prismatic shape, a rectangular shape, a ring shape, or the like.
