Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle deodorization, dust removal, and sterilization apparatus for purifying the interior environment of a vehicle such as an automobile, a railway vehicle, a ship, and an aircraft.
[0002]
[Prior art]
Conventionally, as an air cleaning device for vehicles, a filter that traps impurities in the air, adsorbs or neutralizes odorous components in the blower, or a vehicle interior that uses high-pressure corona discharge. Those that increase the ion concentration are known.
[0003]
[Problems to be solved by the invention]
However, the former prior art has a problem in that the adsorption or neutralization effect of the filter deteriorates with time and the filter is clogged with trapped contaminants, which necessitates periodic cleaning and replacement of the filter. It was.
On the other hand, a device using this technology may be able to remove rough dust and temporary odors in the car, but it only has a symptomatic effect, for example, in the car seat and carpet fibers. At present, it has not been possible to remove dust, germs, and odor components accumulated in the gaps or in the air supply passage of the air conditioner.
This is because there is a limit to the fineness of contaminants that can be captured by the filter, and there is a possibility that fine dust and germs may pass through the filter and that the ability to adsorb or neutralize odorous components is limited. to cause.
In addition, in order to obtain a sufficient cleaning effect, a filter having a large contact area with the passing outside air is required. On the other hand, the air blowing mechanism also needs to have an air volume corresponding to this, resulting in an increase in the size of the device and the inside of the vehicle. It can also be pointed out that it is unrealistic to distribute.
[0004]
In the latter prior art, there is also a problem that ozone is generated in an amount that has an unknown effect on the human body.
[0005]
[Means for Solving the Problems]
This invention was created in view of the above-mentioned problems of the prior art, and has a high deodorizing, dust removing and sterilizing effect by an extremely small device, and further eliminates a member or a movable mechanism requiring maintenance. An object is to provide a deodorizing, dust removing and sterilizing apparatus.
That is, the deodorizing, dust removing, and sterilizing apparatus of the present invention is arranged in the case that can be brought into the vehicle with a duct having an inlet and an outlet communicating with the outside, and disposed in the vicinity of the liquid hole communicating with the liquid flow path. A negative pressure region is formed by ejecting compressed air from the air hole, and a nozzle that sucks and sprays liquid from the liquid hole is disposed in the duct, thereby forming a mist atmosphere in the duct. By narrowing the space of the duct in the vicinity of the nozzle, the outside air is introduced into the duct by a negative pressure generated by spraying from the nozzle, and is then discharged.
[0006]
This invention introduces air in the vehicle into the duct and makes it contact with the mist, thereby removing germs, dust, odor components, etc. in the air and increasing the concentration of anions in the air to clean it. This produces an effect of discharging.
[0007]
By introducing outside air into the processing chamber where the mist atmosphere is formed and bringing the outside air into contact with the mist, the mist captures and removes germs, dust, odor components, etc., and then discharges the outside air to the outside of the processing chamber. The technique has long been known as a wet dust collector (for example, JP-A-52-58274, JP-A-56-16042, JP-A-56-119434, JP-A-57-44897, JP-A-57-44897). No. 58-84019, JP-A No. 62-61615, JP-A No. 8-89739, etc.).
The present invention applies this technique to remove germs, dust, odor components, etc. in the air in the vehicle.
[0008]
On the other hand, a technology has been known for a long time to introduce air into a processing chamber in which a mist atmosphere is formed and bring the air and mist into contact with each other to increase the concentration of anions in the air and then discharge the air out of the processing chamber. (For example, French Patent No. 1245534, Aug. 22, 1960, JP-B-5-58755, JP-B-7-62534, JP-A-6-262023, JP-A-8-66456, Patent No. No. 2706632).
More specifically, this type of device utilizes a phenomenon in which the concentration of ions in the air increases when water breaks up and breaks into fine water droplets (mist).
This phenomenon has been known as an empirical fact that the place where water ruptures and mist occurs due to natural phenomena such as the waterfalls and the seaside shores is good for the body since ancient times, but theoretically at the beginning of this century Nobel physicist P.C. When Dr. Lenard collides with a metal plate and splits, ions are generated in the nearby air, and the sum of the charge amount of the split water drops is greater than the amount of electricity in the first water drop. It has come to be recognized as the so-called “Leonard effect”, which proves that the sum of the charges of the generated ions and the amount of electricity of the water droplets increased by the splitting are equal.
The present invention applies this technique to increase the concentration of anions in the air in the vehicle to obtain a deodorizing effect.
[0009]
By the way, in the above-mentioned prior art, a known apparatus originally developed for industrial use (for example, the above-mentioned Japanese Patent Publication No. 5-58755, Japanese Patent Application Laid-Open No. 57-44897, etc.) is pressurized to form a mist atmosphere. The sprayed water was sprayed from the nozzle in the cyclone, so the device became large and could not be used in the car.
Further, in this apparatus, there is a problem that the nozzles are easily clogged and that regular maintenance is required.
[0010]
Also, in known devices (for example, the above-mentioned Japanese Patent Publication Nos. 5-58755 and 7-62534) that form a mist atmosphere by causing a liquid to collide with a rotating plate or blades, a power device for the rotation mechanism is provided. As long as it is provided, the size of the device is limited, and in order to achieve the desired performance, it is necessary that the rotating plate and the rotating blade have a predetermined size. There was a limit.
[0011]
Furthermore, as a structure common to the above devices, a blower device for introducing and discharging outside air into the processing chamber is indispensable separately from the device that forms the mist atmosphere. There was a limit.
[0012]
The deodorizing, dust removing, and sterilizing apparatus of the present invention provides a mist atmosphere by arranging a nozzle that sucks and sprays liquid from a liquid hole by a negative pressure generated by jetting compressed air in a duct with a narrow space in the vicinity. Since the combined action of the formation of air and air supply in the duct is realized, a rotating plate for forming a mist atmosphere and a blower for air supply as in the prior art are not required, and the apparatus is extremely miniaturized. This produces an effect that makes possible.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a sectional view showing an example of a vehicle deodorizing, dust removing and sterilizing apparatus according to the present invention.
Reference numeral C in the figure is a case constituting the main body of this apparatus.
The case C is assumed to have portability that can be brought into the vehicle. The duct 1 is provided inside, and a storage portion C1 in which the liquid W (water here) is stored is provided below.
[0014]
The duct 1 communicates an inlet and an outlet to the outside, introduces air in the vehicle, cleans it, and discharges it into the vehicle. In this embodiment, the case C includes a plurality of partition walls. By providing 1A, a folded passage is formed with the entrance 2 on one side of the case and the exit 3 on the upper side to form the duct 1.
Note that reference numeral 5 in the figure denotes a blow-out opening provided above the case C from the outlet 3 of the duct 1, and two are provided here (see FIG. 2).
[0015]
Reference numeral 10 in the figure denotes a nozzle for spraying liquid into the duct 1.
The nozzle 10 has a known structure in which a negative pressure region is formed by ejecting compressed air from an air hole disposed in the vicinity of a liquid hole communicating with a liquid flow path, and the liquid is sucked and sprayed from the liquid hole. A spray nozzle.
Here, as an example, one end of the liquid flow path 11 disposed in the center is opened at the nozzle end to form the liquid hole 12, and one end of the compressed air flow path 14 disposed around the liquid flow path 11 is the nozzle. An example is shown in which the air holes 15 are opened at the end portions (here, four air holes 12 centered on the liquid holes 12 and two on the outside thereof are shown) (see FIG. 3 and FIG. 3). 4).
Reference numeral 11A in the figure is a needle-like valve whose conical tip advances and retreats toward the liquid hole 12 in order to adjust the spray amount with the size of the liquid hole 12 being variable. The amount of advance and retreat is adjusted by an adjustment knob 11B provided behind the nozzle.
Reference numeral 14A in the drawing is a valve that controls the amount of air supplied from the compressed air source to the flow path 14 of the compressed air in order to adjust the spray amount by varying the amount of compressed air ejected from the air hole 15. The opening / closing amount is adjusted by an adjustment knob 14B provided behind the nozzle.
[0016]
The nozzle 10 is arranged near the inlet of the duct 1 with the spray side facing the outlet side of the duct, thereby forming a mist atmosphere in the duct and narrowing the duct space 4 near the nozzle. The outside air is introduced into the duct from the inlet 2 by a negative pressure caused by spraying, and discharged.
Here, the upper and lower partition walls 1A of the duct 1 near the nozzle 10 are used as means for narrowing the space 4 near the nozzle by projecting in a wedge shape toward the nozzle. When close to the partition, the duct space 4 formed by the gap between the two is narrowed, so it goes without saying that it is not necessary to project this partition.
[0017]
The liquid flow path 11 of the nozzle 10 communicates with a suction pipe 13 that is suspended from the nozzle toward the storage portion C1, and the liquid W in the storage portion C1 is sucked into the nozzle through the suction pipe 13. As a result, a mist atmosphere is formed in the duct 1.
On the other hand, a communication hole 5 that communicates with the reservoir C1 is provided in the middle of the duct 1 so that it adheres to each other in the mist or traps impurities such as germs, dust, and odor components by its own weight. By dropping into the storage part from the communication hole, impurities are removed as a result, and only clean air having an increased anion concentration is discharged from the outlet 3 to the outside.
[0018]
As described above, the compressed air flow path 14 of the nozzle 10 is communicated with an external compressed air source. Here, the compressed air flow path 14 is communicated with the air supply pipe 16 and the air supply pipe. A connection port 16V to which a connection port A of an air supply pipe of a compressed air source such as a compressor (not shown) can be connected is provided at the end of 16 and faces the outside of the case C.
Therefore, in this case, there is an effect that a compressed air source such as a compressor that is permanently installed in a vehicle maintenance factory, a gas station, or the like can be used as a drive source of the apparatus.
[0019]
In the present invention, the stored liquid is contaminated with contaminants such as germs, dust, and odor components trapped in the mist, so this must be drained regularly. In the example, in order to enable this drainage with one touch, the following configuration is adopted.
That is, a drain pipe 20 having a discharge port 21 having one end opened to the outside is disposed above the storage portion C1 in the case C, and a suction pipe 22 reaching the liquid W in the storage portion is connected to the drain pipe to suck the suction pipe. An air supply pipe 23 having one end facing the exhaust port from the pipe is disposed in the drainage pipe, and a connection port 23V to which the connection port A of the air supply pipe of the external compressed air source can be connected is connected to the suction pipe. It is provided at the other end and faces the outside of the case C.
Therefore, if an air supply pipe of a compressed air source is connected to the air supply pipe 23 and compressed air is sent, a negative pressure region is formed on the discharge port 21 side from the suction pipe 22 in the drain pipe 20. Thus, the liquid W in the storage portion C1 is sucked and drained to the outside through the discharge port of the drain pipe.
[0020]
【The invention's effect】
The present invention configured as described above has the following specific effects.
(1) By arranging a nozzle that sucks and sprays liquid from the liquid hole due to the negative pressure generated by the blowout of compressed air in a duct with a narrow space in the vicinity, the formation of a mist atmosphere and the supply of air in the duct Realizing a complex action eliminates the need for a rotating plate for forming a mist atmosphere and a blower for air supply as in the prior art, and makes it possible to downsize the deodorizing, dust removing, and sterilizing device extremely. Become.
[0021]
(2) Therefore, since a device having a very large air volume can be brought into a limited vehicle, the air in the vehicle can be circulated strongly, and the gap between the fiber in the vehicle seat and carpet, which has been difficult with the prior art, or It is possible to remove dust, germs, and odor components accumulated in the air supply passage of the air conditioner by drawing them into the device.
[0022]
(3) In particular, as in the embodiment, if the apparatus itself does not have an independent compressed air source, and compressed air is supplied from an external compressed air source through a connection port provided in the apparatus, It becomes possible to use a compressed air source such as a compressor that is permanently installed in a maintenance shop or a gas station as a drive source of this device, and to use this compressed air source to make a device having an extremely large air volume. Since this is possible, the above effect is further enhanced.
[0023]
(4) Gaseous bacteria, dust, odor components, etc. are captured and removed by mist, and the deodorizing effect of anions is used. Therefore, it is much finer than conventional devices using filters. Things can be removed, and effective deodorization is also possible.
[0024]
(5) Since the liquid is sucked and sprayed from the liquid hole by the negative pressure generated by the ejection of the compressed air, there is no possibility of clogging as in the case where the pressurized water is sprayed from the nozzle.
[0025]
(6) As described above, the deodorization, dust removal and sterilization apparatus of the present invention has an extremely large air volume, can remove even fine impurities, and can also be expected to have a deodorizing effect due to anions. When used in a car, it can be removed for a short period of time in the car, removing impurities in the car air, complete deodorization, and removing the odors in the car unique to used cars. It becomes possible, and coupled with the fact that a compressed air source is permanently installed in a maintenance shop, a gas station, etc., a new means of regenerating used cars will be created.
