Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electric dust collector with an ashtray that efficiently collects smoke generated from cigarette butts in an ashtray and collects dust.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there is an electric precipitator that applies a high voltage to an ionizer to generate corona discharge, thereby collecting dust. Some of these types of electric precipitators are equipped with an ashtray, which can suck smoke generated from cigarette butts and ashes in the ashtray (see Japanese Utility Model Application Laid-Open No. 62-107695).

As shown in FIG. 1, a conventional ashtray-equipped electric dust collector 10 is provided with a housing 12 having an intake port 30 that opens upward on both sides of the ashtray 14, and is provided in the housing 12. An electric dust collecting mechanism 16 that collects dust when applied is provided, and a cross flow fan 18 that sucks air sucked from the intake port 30 so as to pass through the electric dust collecting mechanism 16.

Since the conventional dust collector 10 with ashtray has such a configuration, smoke generated from cigarette butts, ash and the like in the ashtray 14 is once drawn into the atmosphere and then sucked through the intake port 30. You. The sucked air descends in the housing 12 by the suction force of the cross flow fan 18, passes through the electric dust collecting mechanism 16, is collected into dust, and is discharged from the outlet 19 into the atmosphere. The arrows in the figure indicate the flow of the air to be sucked.

[0005]

[Problems to be solved by the invention]

 As described above, the conventional electric dust collector with an ashtray uses a parabolic suction method in which the smoke generated from the cigarette butts and ash in the ashtray 14 is a parabolic suction that is once drawn into the atmosphere and then sucked. There is a technical problem that cannot be captured.

As a means for solving this problem, it is conceivable to increase the suction force by increasing the wind force of the cross flow fan 18. However, since the cross-flow fan 18 is installed below the electric dust collecting mechanism 16 and has a role of sending air to the electric dust collecting mechanism 16, if the suction force of the cross-flow fan 18 is increased, the sucked air causes the electric dust collecting mechanism to work. This will create a new technical challenge of passing early and reducing the dust collection effect.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above technical problems, and aims to provide an electric dust collector with an ashtray that can sufficiently capture smoke generated from cigarette butts and ash in the ashtray. Specifically, a housing having an air inlet, an ashtray provided near the air inlet of the housing, an electric dust collecting mechanism provided in the housing and collecting dust by applying a high voltage, An ashtray-equipped electrostatic precipitator, comprising: a first intake fan that passes through an electric dust collection mechanism and sucks air sucked from the suction port; It features a fan.

As described above, according to the present invention, the second intake fan for sucking air is provided in the vicinity of the intake port separately from the first intake fan. As a result, the suction power can be increased, and smoke generated from cigarette butts and ash in the ashtray can be captured as sufficiently as possible.

[0009]

[Embodiment of the invention]

 In the electric dust collector with an ashtray according to the present invention, a housing having an intake port, an ashtray provided between the two intake ports of the housing, and an ashtray provided in the housing are provided by applying a high voltage. An electric dust collector equipped with an ashtray, comprising: an electric dust collecting mechanism for performing dust; and a cross-flow fan (first air suction fan) for passing the electric dust collecting mechanism and sucking the air sucked from the intake port. In addition, a case fan (second intake fan) for sucking air is provided in the vicinity of the intake port, and the electrostatic precipitator includes an ionizer for ionizing tobacco smoke particles and the like and an ionized tobacco smoke particle and the like. The one provided with a dust collecting electrode for collecting dust by the Coulomb force is used.

It is preferable that the intake port is formed so as to be inclined toward the ashtray at an angle of 30 to 90 degrees with respect to a horizontal plane, and the case fan is also installed along the inclination angle of the intake port. Is preferred.

[0011] By installing the intake port inclined at such an angle, a horizontal air flow can be formed above the ashtray, so that smoke generated from cigarette butts, ash, etc. in the ashtray can be reduced. The air can be sucked into the intake port without being raised as much as possible.

The two case fans are preferably provided with a pair of intake ports opposed to each other with an ashtray interposed therebetween, and the two case fans are preferably configured so that one of them rotates clockwise and the other rotates counterclockwise. In this way, if the suction is performed by rotating one of the case fans clockwise and the other to the left, the flow of air is mutually different from the case where the suction is performed by rotating the case fans in the same direction. There is little interference and air can flow smoothly.

[0013] Further, both the case fans are configured to rotate in the air suction direction as described above, or one of the case fans rotates in the air suction direction and the other rotates in the air discharge direction. May be configured. In this way, if the case fans are rotated in the direction of sucking air, surrounding smoke can be captured as sufficiently as possible. In addition, by rotating one of the two case fans in the direction of sucking air and rotating the other in the direction of discharging air, the air is more horizontal than in the case of rotating both case fans in the direction of sucking air. It can flow in one direction (the direction from the other case fan to the one case fan) and double the suction power of smoke, so that smoke can be captured more sufficiently.

It is preferable that the wind force of the second intake fan is configured to be weaker than that of the first intake fan. If the wind power of the second intake fan is strong, ash and butts in the ashtray may scatter, and if a fire remains in these, a fire may occur. Thereby, it is possible to prevent the ash and the like in the ashtray from scattering.

[0015] It is preferable to provide a pre-filter at both of the air inlets in order to prevent dust and ash of tobacco from entering the housing and to prevent the case fan and the like from touching the hand.

[0016]

【Example】

 Next, an embodiment of the electric dust collector with an ashtray according to the present invention will be described with reference to the drawings. FIG. 2 is a front sectional view of the present embodiment, and FIG. 3 is a partially enlarged sectional view of FIG.

The electric dust collector 10 with an ashtray according to the present embodiment includes a housing 12, an ashtray 14 provided in an upper central portion of the housing 12, and an ashtray 14 provided in the housing 12. An electric dust collecting mechanism 16 that performs dust and a cross flow fan 18 that sucks air so as to pass through the electric dust collecting mechanism 16 are provided.

The housing 12 is formed of a rectangular parallelepiped with an open top surface, and a cover member 22 is provided on the open surface. An opening 22A is formed in the center of the lid member 22, and the ashtray 14 is detachably installed in the opening 22A. Below the ashtray 14, an ashtray cover 15 is provided. By providing the ashtray cover 15, it is possible to prevent ashes and butts falling out of the ashtray 14 from entering the electric dust collecting mechanism 16 and to prevent the hand from touching the electric dust collecting mechanism 16 when the ashtray 14 is removed. it can. The lid member 22 has a pair of intake ports 22B, 22B with the opening 22A symmetrical.

Above the lid member 22, a suction duct 36 is placed. The suction duct 36 is formed with a pair of suction ports 30, 30 that open horizontally toward the ashtray 14, and air is sucked into the housing 12 from the suction port 30. Each intake port 30 is provided with a first pre-filter 32 for preventing dust, tobacco ash, etc. from entering the housing 12. The first pre-filter 32 prevents dust, ash of tobacco, and the like from entering the housing 12 and prevents a case fan 34 described later from touching a hand. The first pre-filter 32 is made of sheet metal in consideration of the fact that ash of cigarettes or the like may be ignited.

Further, inside each of the first pre-filters 32, 32, there are provided case fans 34, 34 for sucking air into the housing 12, and the case fans 34 are arranged as shown in FIG. It is supported by the case fan support member 26 at an angle θ of 30 to 90 degrees with respect to the horizontal plane. The back surface (the surface facing the case fan 34) 26A of the case fan support member 26 is formed so as to be inclined toward the case fan 34. In this manner, by inclining the back surface 26A of the case fan support member 26, the flow of the air sucked by the case fan 34 can be improved, and the air sucked by the case fan 34 can be smoothly changed by the cross flow fan 18. It can be combined with the air flow.

In the present embodiment, both the case fans 34, 34 are formed so that one of them rotates clockwise and the other rotates counterclockwise, and the wind power of the case fans 34, 34 is smaller than that of the cross flow fan 18. It is weakly structured.

As described above, by providing the case fan 34 near the intake port 30, smoke generated from cigarette butts, ash, and the like in the ashtray 14 can be captured as sufficiently as possible. In particular, in the present embodiment, the case fan 34 is provided separately from the cross flow fan 18, so that the air suction force on the ashtray 14 can be improved without increasing the wind power of the cross flow fan 18. Therefore, the speed of the air passing through the electric dust collecting mechanism 16 is not increased, and the dust collecting efficiency is not reduced.

Further, since the case fan 34 is installed within the range of the above-described angle θ, as shown in FIG. 3, a horizontal air flow is formed above the ashtray 14, and the inside of the ashtray 14 is formed. Smoke generated from cigarette butts and ash can be sucked into the intake port without raising it to the atmosphere as much as possible.

Further, by rotating one of the two case fans 34, 34 clockwise and the other counterclockwise, the air flow is less likely to interfere than when the case fans 34, 34 are rotated in the same direction. The air can flow smoothly with little.

Further, by configuring the case fans 34 and 34 to weaken the wind force, it is possible to prevent ash and the like in the ashtray 14 from scattering.

A detachable panel (not shown) is mounted on the front surface of the housing 12. When the panel is removed, a panel detachable limit switch SW 1 that shuts off the main power supply of the electric dust collector 10 is operated. In this way, by configuring the main power supply of the electrostatic precipitator 10 to be shut off, electric shock caused by touching the electric precipitator 16 and the like and injuries when inspecting or replacing the electric precipitator 16 for maintenance or the like are performed. Can be prevented.

An electric dust collecting mechanism 16 is installed near the center of the housing 12, and a cross flow fan 18 is installed below it. The electric dust collecting mechanism 16 includes an ionizer 16A for ionizing tobacco smoke particles and the like, and a dust collecting electrode 16B for collecting ionized tobacco smoke particles and the like by Coulomb force. In this embodiment, an insulating film is adhered to the surface of the dust collecting electrode 16B. Therefore, even if foreign matter enters the electric dust collecting mechanism 16, an arc discharge does not normally occur, but the insulating film is If the electrode is stripped off, an arc discharge may occur. In this case, the arc discharge can be detected by a known detection device.

A sheet metal second pre-filter 44 is provided above the electric dust collecting mechanism 16, and the second pre-filter 44 allows the first pre-filter 32 to catch the dust. Dust and tobacco ash that could not be captured can be captured. Further, a discharge port 43 is formed below the cross-flow fan 18 of the housing 12 to pass the dust collected through the housing 12 to the atmosphere. A deodorizing filter 45 made of activated carbon capable of removing odor components (such as tobacco odor) is provided.

The electric dust collector with ashtray 10 according to the present embodiment is provided with a fall prevention limit switch SW2 that shuts off a main power supply even when the fall occurs.

As described above, in this embodiment, one of the two case fans 34, 34 is configured to rotate clockwise and the other is configured to rotate counterclockwise, but the case fans 34, 34 are configured to rotate in the same direction. The case fans 34, 34 may be configured so that one of them rotates in the direction of sucking air and the other rotates in the direction of discharging air.

[Effect of the invention]

 The present invention is embodied in the form described above and has the following effects.

In the present invention, since the second intake fan is provided near the intake port, smoke generated from cigarette butts, ash, etc. in the ashtray can be captured as sufficiently as possible. That is, in the present invention, since the second intake fan is provided separately from the first intake fan, the air suction force can be improved without increasing the suction force of the first intake fan. Therefore, the speed of the air passing through the electric dust collection mechanism is not increased, and the dust collection efficiency is not reduced. Therefore, the present invention provides an electric dust collector with an ashtray capable of sucking smoke generated from cigarette butts, ash, etc. in the ashtray as sufficiently as possible.

In addition, since the plurality of intake ports are provided to face each other with the ashtray interposed therebetween, one of the second intake fans of the intake ports is rotated in a direction for sucking air, and the other is rotated in a direction for discharging intake air. By rotating, the flow of smoke can be made to flow in a substantially horizontal direction, which has the effect of further enhancing the capture of smoke.

Further, by making the wind power of the second intake fan weaker than that of the first intake fan, it is possible to prevent ash and the like in the ashtray from scattering.
