Abstract

PROBLEM TO BE SOLVED: To provide an ashtray for cigarette capable of improving sanitation by eliminating diffusion of a tobacco smoke to the out side. SOLUTION: When a fan 37 for sucking air and an impeller 39 for a pump are rotated, a smoke from a half-finished cigarette 6 is made to flow from an air inlet 21 toward a gap 25. Water in a water receiving part 9 is sent from a conduit 34 to a water tank 29 by a water pump 41 and is dropped from a slit 29a along an inner peripheral face of an outer column 15 while forming a water film. Since a DC voltage of about 5 to 15KV is impressed between the water film and an electrode group 45, a corona discharge is generated from the tip of the electrode group 45 toward the water film and particles of the smoke are made into charged particles in a process in which the smoke rises through the gap 25. The particles receive Coulomb's force by the electric field between the electrode group 45 and the water film and dissolved in the water film. A nasty smell component produced from the particles is thrown to the water film by an ionic wind generating from the electrode group 45 toward the water film and dissolved in the water film. Consequently, dust collection and deodorization are simultaneously carried out.

[0004]

According to a first aspect of the present invention, there is provided an ashtray for a cigarette, comprising: a tray having a cigarette placing portion for placing a cigarette; and an air cleaning device detachably attached to the tray. , An air flow generating device for generating an air flow flowing into the air cleaning device from the cigarette mounting portion. Then, the air purifying device includes a discharge electrode provided in a flow path of an inflowing air flow, and a dust collecting electrode using water.

According to this structure, the smoke from the cigarette placed on the cigarette placing section is sent into the air purifying apparatus by the air flow flowing from the cigarette placing section into the air purifying apparatus. Less likely to be dissipated outside the ashtray. Further, since the smoke sent into the air cleaning device adheres to and dissolves in the water as the dust collecting electrode, there is no possibility of re-scattering after the dust is collected, and the dust collecting performance is good. Further, since the water after dust collection can be discharged by removing the tray from the air cleaning device, the cleanability and hygiene are good.

In a preferred embodiment of the first aspect of the present invention, the discharge electrode employs a plurality of needle-shaped electrodes facing a water collecting electrode at a predetermined distance. According to this configuration, since the needle-shaped electrode is used as the discharge electrode, an extremely high electric field appears due to corona discharge at the tip of the needle and ionic wind is generated, so that the dust collection performance and the deodorization performance are improved.

In another preferred embodiment other than the above,
The water for forming the dust collecting electrode is circulated by the water circulating means through a circulation path including a facing surface of the member facing the discharge electrode with a predetermined gap in the flow path of the air flow in the air cleaning device. Can be moved.

According to this structure, since the water after dust collection moves from the facing surface, clean water is always supplied to the facing surface, so that the dust collecting performance of the water used as the dust collecting electrode is improved. In addition, the cleaning property is good and hygienic, unlike the case where a fixed member is used as the dust collecting electrode.

In another preferred embodiment other than the above,
An inlet for the air flow flowing into the air cleaning device is provided in the tray. Therefore, the smoke from the smoked cigarette placed on the cigarette placing section is surely sucked into the air purifying device from the tray, so that it can be prevented from being diffused to the outside.

In another preferred embodiment other than the above,
An air flow guide portion that guides the air flow flowing into the flow path of the air flow toward the tip of the discharge electrode is formed on the holding member that holds the discharge electrode. Therefore, it is possible to prevent the cigarette smoke from staying at the base of the discharge electrode where the corona discharge and the ionic wind are less likely to occur and in the vicinity thereof, and to reliably collect dust and deodorize.

In another preferred embodiment other than the above,
The air flow outlet after passing through the air flow passage is arranged outside the saucer so as to blow out the air in the direction in which the air flows from the cigarette placing portion toward the saucer, and the blown out air flow is the saucer. It is designed to be directed inward. Therefore, it is possible to form an air curtain for forcibly introducing the smoke from the smoked cigarette placed on the cigarette placing part to the introduction port, and even if the cigarette smoke goes out of the saucer, Since it is forcibly introduced into the air cleaning device from the tray by the air curtain, the air cleaning effect is good.

Further, in another preferred embodiment other than the above,
The amount of air flow blown from the exhaust port is set to be smaller than the amount of air flow flowing from the air flow inlet port. Therefore, the forced introduction of cigarette smoke into the inlet by the air curtain is promoted.

FIG. 2 is an enlarged cross-sectional view of a portion indicated by reference numeral A of the above-mentioned cigarette ashtray.

Each of the electrodes 45a to 45 constituting the electrode group 45
A needle electrode is used for n as shown in FIG.
This electrode group 45 and the outer cylinder 15 to function as a dust collecting electrode
A DC voltage of about 5 to 15 KV is applied from the DC power supply 51 to the water film 49 formed along the inner peripheral surface of the electrode, with the water film 49 side being positive and the electrode group 45 side being negative. ing. By applying this DC voltage, each of the electrodes 45a to 45n
A corona discharge is generated from the tip of the electrode toward the water film 49, and the corona discharge and the electric field between the electrode group 45 and the water film 49 remove dust and odorous components. The process of collecting dust and removing malodorous components will be described in detail later.

Guide to pass between 9 and.

FIG. 3 is an enlarged cross-sectional view of a portion indicated by reference numeral B of the above-mentioned cigarette ashtray.

As shown in FIG. 3, the tip portion 23 of the outer cylinder 15 forms a water film 49 along the inner peripheral surface of the outer cylinder 15 from the slit 29a (see FIG. 1) of the water tank 29. Not only is the water reservoir 55 that temporarily stores the falling water formed, but also a water introduction guide 57 that guides the water overflowing from the water reservoir 55 to the water receiver 9. Note that the bottom surface of the water reservoir 55 and the side surface of the water introduction guide 57 are smoked from the sucked cigarette 6 guided toward each air intake port 21 by an air curtain formed by the air discharged from the air discharge port 33b. It also serves as a guide for guiding the air flow containing the above so as to flow into the gap 25 via the upper part of the ashtray part 11 and the water receiving part 9 as shown by the thin arrow.

FIG. 4 is an enlarged sectional view of the tray 1 which constitutes the above-mentioned cigarette ashtray.

In the receiving tray 1, the water in the water receiving portion 9 can be replaced, and the ash 8 and the cigarette butts 10 in the ashtray portion 13 can be easily discarded by simply removing the air cleaning device 3 from the receiving tray 1. There is no need to replace any filters, such as those found in cigarette ashtrays.

Next, FIG. 5 showing the flow of air in the above apparatus, showing the process of collecting the particles of cigarette smoke by the cigarette ashtray having the above-described structure and the process of deodorizing the malodorous components generated from the particles, and FIG. A description will be given with reference to FIG. 6 showing the flow of water in the above apparatus, respectively.

When the air suction fan 37 and the pump impeller 39 are rotated by driving the AC motor 47, the smoke from the sucked tobacco 6 placed on the flange portion 7 is blown by the fan 37 in FIG. As shown by the arrows, the air flows from each air intake port 21 toward the gap 25.
On the other hand, the water in the water receiving section 9 is rotated by the impeller 39,
As shown by the thick arrow in FIG. 6, the water is pumped up by the pump 41 and sent to the water tank 29 through the water conduit 43. Then, the water film 49 is dropped from the slit 29a along the inner peripheral surface of the outer cylinder 15 while forming a water film 49.

As described above, the water film 49 and the electrode group 4
5, a DC voltage of about 5 to 15 KV is applied from the DC power supply 51, so that corona discharge is generated from the tips of the electrodes 45a to 45n toward the water film 49.
Therefore, in the process in which the above-described air flow containing cigarette smoke rises through the gap 25 from below along the bottom surface of the water reservoir 55 and the side surface of the water introduction guide 57, the cigarette smoke particles are charged by corona discharge. It becomes charged particles. The charged particles receive a Coulomb force due to the electric field between the electrode group 45 and the water film 49, and the charged particles adhere to the water film 49 and melt into the water film 49.

A coronal discharge is generated between the electrode group 45 and the water film 49, and an ionic wind is generated from the electrode group 45 toward the water film 49, so that it is represented by gaseous ammonia or acetic acid generated from the particles. The malodorous component such as carboxylic acid is hit against the water film 49 by this ionic wind and dissolves in the water film 49. That is, dust collection and deodorization are performed simultaneously between the electrode group 45 and the water film 49.

When the air flow containing the above-mentioned cigarette smoke rises in the gap 25, it is guided by each convex portion 53 so as to pass between the tip portion of the electrode group 45 and the water film 49. It The reason is that corona discharge is generated from the tips of the electrodes 45a to 45n toward the water film 49, so that ionic wind does not occur at the bases of the electrodes 45a to 45n and in the vicinity thereof, and particles are generated at these sites. This is because, if there is a malodorous component or odorous component, these cannot be moved to the water film 49 side. Further, the charged particles lose their electric charge when they reach the water film 49, but since the dust collecting electrode is the water film 49 formed by the water that is falling downward, it may dissolve in the water film 49. Therefore, it will not be scattered in the air again.

In this way, the water film 49 containing particles and malodorous components falls along the inner peripheral surface of the outer cylinder 15 and is temporarily stored in the water storage portion 55. And the water reservoir 55
The water that overflows from the water drops along the side surface of the water introduction guide 57 and is stored in the water receiver 9. The water stored in the water receiving portion 9 is sent into the water tank 29 again by the pump 41, and the water film 49 is formed again as in the above. This operation can be repeated until the water in the water receiver 9 is exhausted.

On the other hand, the air flow from which particles and malodorous components have been removed by passing through the gap 25 passes through the lower air suction chamber 35 and the upper air suction chamber 33 as shown by the thin arrow in FIG. The part is discharged from the air discharge port 33a to the upper side of the device, and the rest is discharged from the air discharge port 33b to the lower side of the device to form an air curtain.

As described above, since the air curtain is formed only by the air flow discharged from the air discharge port 33b to the lower side of the device, the balance of the amount of air flowing into and out of the air cleaning device 3 is changed. Suction of the smoke-containing air flow of the smoked cigarette 6 on the flange portion 7 into the air cleaning device 3 through the air suction port 21 is promoted.

As described above, according to one embodiment of the present invention, the particles of cigarette smoke become charged particles due to corona discharge and dissolve into the water film 49, and the gaseous ammonia and acetic acid generated from the particles are dissolved. A malodorous component such as a carboxylic acid, which is typical, dissolves in the water film 49 by the ionic wind generated from the electrode group 45 toward the water film 49, so that dust collection and deodorization can be performed at the same time.

Further, since the dust collecting electrode is the water film 49, even if the cigarette smoke particles reach the water film 49 and lose the electric charge, they are dissolved in the water film 49 and are thus scattered into the air again. There is no such thing. Water contaminated by the particles dissolved therein can be drained after removing the tray 1 from the air cleaning device 3,
Since this drainage can be used for cleaning, it has good cleanability and is hygienic.

In addition, the air flow containing the smoke of cigarettes produces a gap 2.
5 is moved upward, the electrode group 4
Since each of the electrodes 45 is guided so as to pass between the tip portion of 5 and the water film 49, no corona discharge or ionic wind is generated in each electrode 45.
It is possible to prevent particles and malodorous components from moving to the bases a to 45n and the vicinity thereof.

Further, since the air curtain is formed only by the air flow discharged from the air discharge port 33b to the lower side of the device, the balance of the balance of the amount of air flowing in and out of the air cleaning device 3 is changed, so that the flange portion is formed. It is possible to accelerate the suction of the smoke-containing air flow of the smoked cigarette 6 in 7 through the air suction port 21 into the air cleaning device 3.

Furthermore, the exchange of water in the water receiving portion 9 and the disposal of the ash 8 and the cigarette butts 10 in the ashtray portion 13 can be easily carried out by simply removing the air cleaning device 3 from the receiving tray 1, and it is possible to perform the usual operation. No replacement of filters etc. is required as in a cigarette ashtray.

FIG. 7 is a plan view showing a cigarette ashtray according to a second embodiment of the present invention, and FIG. 8 is a sectional view taken along line CC ′ of the apparatus shown in FIG.

As shown by the reference numeral 61 in FIG. 9, the ashtray is attached to an appropriate position on the wall surface of the toilet room to prevent the air in the toilet room from being contaminated by smoking during the toilet.

In the ashtray, the corona discharge generated from the discharge electrode composed of the needle-shaped electrode group 63 toward the dust collecting electrode composed of the water 67 in the water receiving portion 65 and the ionic wind generated the both electrodes. This is the same as the first embodiment in that the particles of cigarette smoke and the malodorous component flowing into the gap 69 are dissolved in the water 67 to simultaneously collect dust and deodorize.

However, as the dust collecting electrode, not the water film formed in the process of circulation between the water receiving portion by the pumping pump and the water tank, but the water 67 stored in the water receiving portion 65 in a stationary state. The present embodiment is largely different from the first embodiment in that.

The details of the ashtray will be described below.

The water receiving portion 65 and the ashtray portion 73 adjacent to the water receiving portion 65 both have a rectangular shape, and are respectively formed on the rectangular receiving tray 71. The needle-shaped electrode group 63 is provided in the water receiving portion 65 in a lower space portion 79 of the air purifying device 75 having an opening portion (also functioning as an air suction port) 77 for inserting and removing the receiving tray 71. It is held below a rectangular air introduction guide 81 provided at a predetermined distance to form the gap 69 with the water 67. The peripheral surface of the portion above the opening 77 of the air cleaning device 75 is formed in a semi-cylindrical shape, and in order to discharge the air after dust collection and deodorization, approximately the same surface is formed on this peripheral surface. A plurality of air outlets 83 are formed at intervals. In addition, the air cleaning device 7
Directly above the air introduction guide 81 of No. 5 is a spiral chamber 87 in which an air suction fan 85 for guiding the air containing smoke from sucked tobacco (not shown) to the gap 69 is arranged. . Further, a semi-cylindrical closed chamber 89 is provided above the chamber 87 of the air cleaning device 75. In this chamber 89, an AC motor 91 for driving the fan 85 and a space between the electrode group 63 and the water 67 for generating corona discharge and ionic wind from the tip of the electrode group 63 toward the water 67. Further, a DC power supply 93 for applying a DC voltage of, for example, about 5 to 15 KV is housed therein.

In the above structure, when the fan 85 is rotated by the AC motor 91, the smoke from the sucked tobacco 80 in the ashtray section 73 flows from the air intake port 77 to the gap 69 by the fan 85 as shown by the thin arrow in FIG. Inflow toward. Then, the particles of cigarette smoke and the malodorous component are carried in the direction of the water 67 and dissolved in the water 67 by the corona discharge and the ionic wind generated in the gap 69, so that dust collection and deodorization are simultaneously performed. The air flow thus purified is discharged from the air discharge port 83 to the outside of the device 75 as indicated by a thin arrow.

Also in this ashtray, substantially the same dust collecting effect and deodorizing effect as those of the ashtray according to the first embodiment described above can be obtained.

It should be noted that the contents described above relate to each embodiment of the present invention to the last, and needless to say, the present invention is not limited to the contents described above. For example, in each of the above embodiments, a DC voltage is applied between the discharge electrode and the dust collecting electrode, but an AC voltage or an impulse voltage may be applied.
