Description

The present invention relates to an apparatus for flowing air in a flow path in which an ion atmosphere is formed in order to remove a substance mainly composed of liquid or solid particles floating in the air and purifying the same.

  Substances consisting of liquid and solid particles floating in the air pollute the air and have an undesirable effect on the human body, both physically and mentally. Cigarette smoke is a major removal target in air purification because of its strong odor, strong adhesion, and the magnitude of the effects of passive smoking. Needless to say, various techniques for removing suspended substances have been proposed for the purpose of air purification. For example, the invention of Japanese Patent Application Laid-Open No. 2001-321661 supplies negative ions uniformly indoors. For this purpose, a configuration is disclosed in which the direction in which the tip of the discharge electrode faces is opened at an angle of 15 to 45 degrees. The object of the invention is not limited to cigarette smoke, but is intended to eliminate unevenness of negative ion concentration and is not more than that.

  The idea of Utility Model Registration No. 3109054 is that an unpleasant odor caused by cigarette smoke can be removed without using any chemical substances or ozone. For this purpose, an air filter, two kinds of metals and different kinds of materials made of ore and ceramic are arranged in the casing, and a negative ion generator and an ultraviolet radiation device are arranged. However, in the case of this idea, there is no technically new matter, and it seems that it is only a combination of many kinds of substances and devices.

  On the other hand, the invention of Japanese Patent Laid-Open No. 10-43629 is intended to provide an air cleaner that is quiet and can efficiently suck cigarette smoke. In the invention of the same number, an air flow from the suction port to the ejection port is generated by the ionic wind generated in the ionization section, and the indoor air is circulated. Then, a suction attracting plate extending in front of the suction port to the ionization part is provided along the side edge of the suction port, and the tobacco smoke drifting in front of the suction port is guided to the suction port. However, this does not improve the air cleaner itself, and only guides the airflow in a part of the four circumferences around the suction port.

JP 2001-321661 A Utility model registration No. 3109054 JP 10-43629 A

  The present invention has been made paying attention to the above-mentioned points, and its problem is to float including cigarette smoke and, similarly, fine water droplets and hygroscopic particles, mist, and solid particles, dust. It is to enable the material to be collected extremely efficiently by ions. Another object of the present invention is to ensure that suspended substances including mist such as cigarette smoke and dust are guided to an ion atmosphere and collected.

  In order to solve the above-mentioned problems, the present invention is an apparatus for purifying air by flowing air through a flow path in which an ionic atmosphere is formed and removing floating substances composed of liquid or solid particles floating in the air. A main body in which a pair of electrode plates are arranged on the inner surface of a member forming a flat insertion hole to form a socket part having a flat insertion hole, and a plurality of the socket parts are arranged in parallel; In order to form an ion atmosphere with a polarity different from that of the charged polarity and collect suspended substances in the air, the ion generator connected to the pair of electrode plates and the flat insertion hole are inserted. The filter includes a replaceable filter made of paper, and an air suction port for sucking air containing at least floating substances and a cover having an air guiding portion for a flat insertion hole. The inside is a flow path through which air flows, and has numerous projections provided so as to protrude from the inner surface of the filter into the flow path, and the pair of electrode plates are opposed to each other by insertion into the socket portion. The outer surface of the filter can be contacted with the inner surface, and measures are taken so that suspended substances adhere to the surface of the sheet material by flowing air inside the filter in the ion atmosphere formed by starting the ion generator. It is a thing.

  The present invention has an object of collecting floating substances mainly containing fine water droplets and hygroscopic particles mist and solid particles of dust by ions. Therefore, it is considered that the air containing the suspended matter flows through a certain flow path filled with ions and undergoes a process of combining with ions having a polarity opposite to that of the suspended matter. I think that the idea of collecting suspended substances using these ions is almost the same as that of conventional air purification using ions.

  Such an apparatus of the present invention has a main body, an ion generator, a filter and a cover. The main body has a flat insertion hole, and on the inner surface of the member that forms the flat insertion hole, a pair of electrode plates are arranged at a distance to form a socket portion, and a plurality of the socket portions are arranged in parallel. It is arranged in. In the present invention, in order to form an ionic atmosphere in the flow path through which air flows, a pair of electrode plates are arranged at predetermined intervals on the inner surface of the flat insertion hole of the socket portion. Between the opposing inner surfaces of the pair of electrode plates is a flat insertion hole, and this flat insertion hole is an insertion hole for the filter.

  A plurality of the socket parts are arranged in parallel on the main body. Since it is possible to increase / decrease the number of socket portions, the number of socket portions can be easily set according to the amount of air to be processed by the apparatus of the present invention. In other words, it is possible to have an arbitrary processing capability according to the usage from personal use to several people use.

  The ion generator is connected to a pair of electrode plates. Thereby, an ion atmosphere having a polarity different from the charged polarity of the suspended matter is formed between the pair of electrode plates to collect suspended matter in the air. At that time, one ion generator may be provided for each pair of electrode plates, or a single ion generator may be used for all pairs of electrode plates. Other than that. Any ion generator can be used. However, it is most desirable to use an ion generator developed by the applicant and having a pumping circuit connected to the primary side of the main transformer because it is small and high performance.

The ion generator uses, for example, a direct current power source as an energy source, and a high voltage generated by energizing the pumping circuit to the secondary coil of the main transformer by connecting a pumping circuit to the primary coil of the main transformer. A pumping circuit for further boosting the voltage, connecting an ion electrode for outputting a high voltage boosted by the multiplier circuit, and connecting a grounding wire to the secondary coil of the main transformer. A voltage stabilization circuit for stabilizing the primary side voltage is provided in the previous stage of the circuit.
The pumping circuit can be configured to have two NPN transistors arranged so that the circuit leading to the emitter is connected at the midpoint.
The voltage stabilization circuit includes a diode connected to a circuit that leads to the emitters of two transistors, a resistor that is connected to a circuit that leads to a base, and the diode and the resistor connected to the secondary side so that the primary of the main transformer The side can be configured to have a transformer connected to the primary side.
A diode can be inserted in the forward direction between the secondary coil of the main transformer and the ground wire.
A pumping circuit, a voltage stabilizing circuit, a main transformer, and a multiplier circuit that communicate with the DC power supply can be attached to one surface of the circuit board, and a space between these circuit elements can be filled with an insulating resin.

It is assumed that the filter is replaceable using paper as a material inserted into the flat insertion hole. The filter has a flow path through which air flows, and has numerous protrusions provided so as to protrude from the inner surface of the filter into the flow path. The outer surface of the filter is provided so as to be in contact with the inner surfaces facing each other. It is desirable that the sheet material disposed inside the pair of electrode plates be able to contact the electrode plate entirely, and the sheet material is considered to function like a dielectric with respect to the electrode plates.

  The sheet material needs to be an electrical insulator. In the present invention, a paper material is suitable as a sheet material. Paper is various, but in the case of the present invention, since the sheet material is used as a filter for trapping suspended substances including mainly mist and dust, it is easy to process and close to the electrode plate. It is desirable to be as inexpensive as possible for disposable use. In addition, in order to grasp the repair status of suspended solids, it is also a significant condition that the color is close to white or the color changes significantly due to collection.

  Between the sheet materials are air flow paths through which air actually flows, but innumerable protrusions protruding from the surfaces toward the inside of the flow paths are formed on the surfaces of the sheet materials. Whether or not the amount of suspended matter collected has increased remarkably can be confirmed by an increase in color concentration on the surface of the sheet material to which the collected particles are attached. It was confirmed in the development process of the present invention that by providing innumerable protrusions on the surface of the sheet material, a significant increase in the density of the color peculiar to the substance is observed with the increase of suspended matter trapped on the sheet material surface. Has been. The present invention has been made based on the discovery of this phenomenon.

  It is not yet clear how these countless protrusions physically act in the suspended matter collection mechanism. It is presumed that the stirring of the air flow may also cause the adhesion to the sheet material surface to increase. However, it is also observed that the airflow fluctuates near the tip of the protrusion, and it seems that this phenomenon contributes to the collection of suspended solids.

  How to provide an infinite number of protrusions is basically a matter that can be freely determined. For example, an infinite number of protrusions can be provided by electrostatic flocking means. Among them, when paper is used as the sheet material, a hole with uneven crease is formed on the edge by piercing the surface of the paper, and the irregular crease is used as countless protrusions. Thus, the collecting effect of the sheet material on which the protrusions are formed in this way is good. In addition, when a hole with a crease is formed by piercing the surface of the paper, etc., a cover sheet made of similar paper is overlapped on the outside of the paper, and the hole is closed. It is desirable to adopt a configuration (the invention according to claim 2).

  The flow path of the air between the sheet materials made of paper constitutes a filter independent of the electrode plate. After use, it is discarded while collecting suspended substances in the air. This is desirable in practice because it is interchangeable. The suspended substances in the air, including mist and dust, collected by the filter are always taken out of the machine by replacing the filter, so they do not remain in the air cleaner to which the present invention is applied. Odor is less likely to occur.

  Furthermore, the apparatus of the present invention includes a cover having an air suction port for sucking air containing at least a suspended substance and an air guiding portion for a flat insertion hole. The cover is necessary as a means for reliably guiding the air containing the suspended matter such as cigarette smoke to the filter which is the air purifying unit, and the air suction port is an opening surrounded by four circumferences. For example, a person who smokes becomes an opening portion for blowing exhalation toward the person. The air guiding portion is a means for guiding the air sucked into the air suction port to a flat insertion hole, and a filter is set in the insertion hole.

  However, the cover is composed of an air suction port for guiding air into the flat insertion hole of the socket portion, a hood portion having an air guiding portion, and a main body cover portion covering the main body including the ion generating device. It can be formed so as to be separable from the cover portion (the invention according to claim 3). In other words, the cover may cover the entire apparatus, but it may be composed of a plurality of parts. In the case of a plurality of parts, if the hood part is separated from the main body, the socket can be removed by removing only the hood. The filter can be replaced by exposing the flat insertion hole of the part (the invention according to claim 4).

  Furthermore, the apparatus of the present invention has a configuration including an intake fan for sucking and purifying air and then discharging it (the invention according to claim 4). This intake fan is for allowing the air having the optimum speed and capacity for the purification process to be sucked from the air suction port and passed through the filter. The number of the air suction ports and the intake fan is not limited to one, and any number may be provided.

  Since the present invention is configured and operates as described above, the suspended matter containing cigarette smoke and mist, which is mainly fine water droplets and hygroscopic particles, and dust, which is solid particles. In an exchangeable filter made of paper that is inserted into a flat insertion hole and used in an ion atmosphere, the filter can be collected extremely efficiently. Moreover, according to this invention, there exists an effect that the floating substance containing mist and dust like tobacco smoke can be reliably guide | induced to an ion atmosphere, and can be collected.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. The air purification device 10 illustrated in FIG. 1 includes a main body 11, a filter 21, an ion generator 31 and a cover 41. A plurality of socket portions 13 having flat insertion holes 12 are arranged in the main body 11 in parallel. The socket part 13 is formed by arranging a pair of electrode plates 14 and 15 on the inner surface of plate-like members 13a and 13b forming a flat insertion hole 12 (FIG. 3). Are arranged in parallel. See FIG. 6 and FIG.

  The illustrated main body 11 is formed by fixing a plurality of socket portions 13 to upper and lower plate members 16 and 17 at upper and lower ends, and having an integrated structure. Thus, the device 10 according to the present invention is configured as a combination of the main body 11 and the covers that are unitized into an integral structure. Each of the socket portions 13 constituting the main body 11 is provided with the ion generator 31 described above. That is, this corresponds to an example in which one ion generator 31 is provided for each pair of electrode plates (FIGS. 6 and 7).

  The filter 21 pierces the surface of the sheet materials 22 and 23 made of paper to form countless holes 24 with ridges on the edges, and uses the ridges as countless protrusions 25. See FIG. 4 and FIG. When a hole 24 with a crease is formed by piercing the paper surface, etc., cover sheets 26 and 27 made of similar paper are stacked on the outside of the paper so as to be integrated, and the hole is closed. Shall. Reference numeral 28 denotes a frame-shaped spacer having a large number of passages in the vertical direction. The sheet materials 22 and 23 are bonded to both surfaces to form a flow path 20 having a substantially constant interval. In order to expose the countless protrusions 25 of the sheet materials 22 and 23 to the flow path 20, a window-shaped opening 29 having a sufficient area is provided.

  The pair of electrode plates 14 and 15 are connected to the ion generator 31 and are restricted to a polarity different from the charged polarity of the suspended matter in order to collect suspended matter in the air, An ion atmosphere is formed in the flow path 20. In many cases, the suspended substance composed of liquid or solid particles is positively charged, and therefore, the ion generator 31 is suitable to generate negative ions. In FIG. 3, T is the distance between the flow paths 20, W is the same width, and L is the length. The filter 21 is inserted into a filter insertion portion 30 in which a pair of electrode plates 14 and 15 are attached to the inside, and thereby arranged inside the electrode plates 14 and 15 so as to be in contact therewith.

  The pair of electrode plates 14 and 15 are arranged at a predetermined interval, and the interval is sufficiently small with respect to the width of the channel 20 in the filter 21 and the length of the channel. desirable. The meaning is the same as reducing the interval between the flow paths 20. For example, when the width of the flow path 20 is about 100 mm and the length is about 200 mm, good results are obtained when the interval is in the range of 2 to 6 mm, preferably about 4 mm. In this case, the protruding length of the infinite number of protrusions 25 is in the range of 0.1 to 1 mm. Accordingly, the protruding length of the infinite number of protrusions 25 is in the range of a minimum of about 2 percent to a maximum of about 50 percent with respect to the flow path interval.

  The ion generator 31 is illustrated in FIG. In the case of this example, a smoothing capacitor C is inserted in parallel into a power supply unit 32 composed of a DC power supply of plus 4.5 volts, and is connected to the primary side coil of the main transformer 33. A pumping circuit 34 and a primary voltage stabilizing circuit 35 are connected to the primary coil. The pumping circuit 34 is arranged such that a circuit that connects the two transistors 36a and 36b to the respective emitters is connected at an intermediate point. The voltage stabilization circuit 35 includes a diode D1 connected to a circuit leading to the emitters of two transistors, resistors R2 and R3 connected to a circuit leading to the base, and a primary side connected to the primary side of the main transformer 33. Having a transformer T1.

  The secondary coil of the main transformer 33 is connected to the multiplier circuit 37 and the ground wire 38, and the diode D <b> 2 is inserted between the secondary coil of the main transformer 33 and the ground wire 38 in the forward direction. The multiplier circuit is formed by connecting nine diodes D3 to D11 and capacitors C2 to C10 in series, and performs voltage amplification in nine stages. A capacitor C1 in series with the diode D2 is inserted for rectification.

  When such an ion generator 31 is energized, a current having a more stable voltage than that of the voltage stabilization circuit 35 is formed. In the pumping circuit 34, a fluctuation current is generated by the pumping operation of the transistors 36a and 36b. Therefore, a high voltage corresponding to the winding ratio of the main transformer 33 is generated at both ends of the secondary coil of the main transformer 33. This high voltage is amplified twice over nine stages by the multiplication circuit 37 to be a high frequency high voltage of tens of thousands of Hz and −2000 V, and stable negative ions can be generated at the discharge electrode 39.

  Furthermore, the device 10 according to the present invention comprises a cover 41. The illustrated cover 41 has a hood having an air suction port 42 opened to the outside and an air guiding portion 43 for guiding air to the flat insertion holes 12 of the plurality of socket portions 13 arranged in parallel. It consists of the part 44, the main body cover part 45 which covers the circumference | surroundings of the main body 11, and the base 46 which occupies the lowest part (refer FIG. 2). That is, the hood portion 44, the main body cover portion 45, and the base portion 46 cover the entire apparatus of the present invention and are formed to be separable from each other. The main body cover part 45 exposes the flat insertion hole 12 of the socket part 13 by removing the hood part 44, and enables the filter 21 to be replaced.

  Furthermore, the device 10 according to the present invention includes an intake fan 47 for sucking and purifying air and then discharging it. The intake fan 47 allows air to pass through the filter 21 at a speed and capacity optimal for the purification process, and is provided in the base 46. The air suction port 42 provided in the hood portion 44 and the intake fan 47 provided in the base portion 46 are each one, but a plurality of these can be provided depending on the processing situation. It is as follows.

  As can be understood from FIG. 2, the upper and lower plate members 16 and 17 constituting the main body 11 include an upper portion filled with untreated air inside the apparatus, an intermediate portion where air purification processing is performed, and a processing portion. The air chamber is divided into three air chambers for discharging the exhausted air. In the figure, 48 is a pilot lamp showing the operation of the apparatus, and 49 is a power input section shown as an AC adapter connector.

  The case where the action of the air purification device 10 according to the present invention thus generated is used during smoking will be described. The smoker turns on the power and first points the device 10 toward himself / herself. While smoking, place the cigarette as close as possible to the air suction port 42, and make sure that sidestream smoke does not leak out of the device. Causes the exhaled air to be sucked into the air suction port 42 (FIG. 10). The air containing sidestream smoke and exhaled air contains floating substances consisting of fine liquid and solid particles and huge gas molecules, and the upper end is opened from the air guiding portion 43 by the suction action of the intake fan 47. Flows into the filter 21.

  When air containing suspended solids flows into the filter 21, the filter 21, which has a flow path through which the air flows, exists in the negative ion atmosphere, so that the suspended solids are exposed to negative ions. Become. When the contaminated air containing the floating substance composed of positively charged liquid or solid particles is supplied to the flow path filled with the ion atmosphere by the suction means, it is combined with negative ions or the flow path 15 Are adsorbed and deposited on the wall surface and the protrusion 17, and the air is cleaned and flows out from the lower end outlet of the filter 21 to the outside.

  The internal surface of the filter 21 changes to a color peculiar to the suspended matter due to the accumulation of suspended matter, but the trapping effect of the suspended matter is rarely lowered due to the increase in volume. However, as the accumulated amount of suspended solids increases, the odor becomes stronger especially in the case of cigarettes, so the filter 21 is pulled out from the socket part 13 at an appropriate time before it becomes so, and a new filter and Should be replaced.
