Description

  The present invention relates to a gas processing apparatus that raises the concentration of negative ions of gas by bringing gas such as air into contact with mist, or removes germs, dust, odor components, etc. The present invention relates to a gas processing apparatus that is most suitable for use in a passenger room or a luggage room of a vehicle such as a vehicle.

  In order to artificially increase the concentration of negative ions, air is introduced into the processing chamber that created the mist atmosphere, and the air is processed after increasing the concentration of negative ions in the air by bringing the air into contact with the mist. Techniques for discharging outside are known (for example, Patent Documents 1 to 3). 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).

  On the other hand, it is also known in the above-mentioned patent document that gas bacterium, dust, odor components and the like are captured by mist by introducing outside air into the processing chamber that has generated the mist atmosphere and bringing the mist into contact with the outside air. Yes.

  As described above, by introducing the outside air into the processing chamber that generated the mist atmosphere and bringing the outside air and the mist into contact with each other, the concentration of the negative ions in the gas is increased or the components such as bacteria, dust, and odor are removed. A gas processing means for discharging the treated outside air to the outside of the processing chamber after performing the above is known.

  Attempts have also been made to maintain the freshness of food and plants in a fine mist atmosphere.

  In the above gas treatment apparatus, it is known that a large amount of negative ions are generated as the particle size of the scattered mist is reduced, and how efficiently this is performed with a limited capacity. Whether it can be realized is a technical issue. As an invention to solve this, in a processing chamber capable of introducing outside air, by immersing and rotating a cylindrical body with a screw in the lower part in water, pumping water upward from the lower part in the cylinder, The water and air provided above the cylinder collide with a cylindrical water sprinkling part through which air can pass and are allowed to pass through the water to make it mist. The present applicant has already proposed an invention in which a mist atmosphere containing negative ions is formed by being finely crushed by colliding with a cylindrical screen through which water and air arranged in the gas can collide with each other. (Patent Document 4).

  By the way, it has been proposed in Patent Document 5 to use the gas treatment device of the above principle for vehicles such as ships, airplanes, automobiles, and railway vehicles. In this case, the interior environment of the vehicle is not limited to the cabin. For example, if the gas treatment device of the above principle is used in a cargo compartment or a container in the transportation of food or plants, the freshness during transportation is maintained.

French Patent No. 1245534 dated August 22, 1960 Japanese Patent No. 3051055 Japanese Patent No. 3757889 JP 2009-66389 A Japanese Patent No. 3917722

  As described above, in the gas processing apparatus of the above principle, it is indispensable to pump up water in order to generate mist, and a tank for that purpose is installed below. In this case, unlike indoor applications that are installed statically in a smooth place, in vehicles, when the water surface rises and falls due to acceleration due to changes in travel speed, or when traveling on hills, airways, and seaways As a result of the inclination of the vehicle, the phenomenon that the mist generating device is inclined relative to the water surface occurs. This is a big problem in the gas processing apparatus described in Patent Document 4 having a structure in which water existing under the cylinder is pumped by a screw, unlike a structure in which water is forcibly sucked up by the negative pressure from the pump. There was a risk that the water would be interrupted and the pumping could be interrupted.

  The present invention was created for the purpose of providing a vehicle gas treatment apparatus that has solved the above-mentioned problems, and is obtained by immersing and rotating a hollow rotating body with a screw underneath in water. In addition to pumping water upward from the lower part of the rotating body, the water can be scattered in a mist form from a cylindrical sprinkling part through which the water and air provided above the rotating body can pass, so that outside air can be introduced. A gas processing apparatus main body comprising a mist generating part for forming a mist atmosphere in the processing chamber; a floating body for floating the mist generating part in water stored in a water tank in a state where the lower end of the rotating body is immersed in water; and A water tank for suspending the gas processing apparatus main body is provided.

  In addition, here, as the second invention, mist that has been sprayed in a mist form from a cylindrical sprinkler that can pass water and air provided above the rotating body of the mist generator is further disposed around the sprinkler. Also disclosed is a gas processing apparatus for a vehicle that is crushed more finely by causing the water and air to pass through a cylindrical screen that is allowed to pass through.

  In addition, as a third invention, there is also disclosed a vehicle gas treatment apparatus configured in a dome shape in which a lower portion of a rotating body immersed in water is provided at the lower end with an opening for water intake.

  In the present invention, the gas processing apparatus main body is floated in a water tank installed in a vehicle and used. Therefore, it is desirable to provide means for restricting the moving range of the gas processing apparatus main body suspended in the water tank so that it does not collide with the edge of the water tank due to the acceleration due to the change in the traveling speed.

In the present invention, water that is pumped upward from the bottom of the cylindrical body and splashes to the surroundings by the centrifugal force of the rotating cylindrical body collides with a water sprinkling portion that is formed of a cylindrical body through which water and air can pass. By passing through it, it is crushed into a mist and scattered. Examples of the structure of the watering part for this purpose are as follows.
(A) A cylinder with a large number of slits on the outer peripheral wall.
(B) A cylinder with a large number of pores on the outer peripheral wall.
(C) The outer peripheral wall of the cylinder is constituted by a mesh body.

Further, in the second invention, the mist dispersed by the water sprinkling part is allowed to pass through the cylindrical screen that allows water and air disposed around the water sprinkling part to pass therethrough. Crush more finely to form a mist atmosphere containing negative ions. Examples of the screen structure for this purpose are shown below.
(A) A cylinder with a large number of slits on the outer peripheral wall.
(B) A cylinder with a large number of pores on the outer peripheral wall.
(C) The outer peripheral wall of the cylinder is constituted by a mesh body.

  As described above, in the present invention, several structures are assumed as the water spraying part for crushing and scattering water in the form of a mist, and the screen for finely crushing and scattering the mist from the watering part. According to their experiments, it has been confirmed that the structure having a large number of slits in the outer peripheral wall of (A) for both the water sprinkling part and the screen has obtained good results in the negative ion generation effect. .

  The vehicle gas treatment device of the present invention is used with the gas treatment device main body suspended in a water tank installed in the vehicle. In this case, the water surface of the aquarium always tries to keep the level even if the vehicle shakes or tilts, but the gas processing device body that draws water from here also floats on the water, so that the level is always kept following it. At last. Therefore, the phenomenon that the mist generating device is tilted relative to the water surface unlike the prior art does not occur, and water can be pumped stably regardless of the shaking or tilting of the vehicle. Even if the water surface undulates due to acceleration due to changes in travel speed and the water level rises and falls, it is still possible to pump water stably.

  On the other hand, the vehicle gas treatment apparatus according to the second aspect of the present invention is configured in a dome shape in which a lower portion of a rotating body immersed in water is provided with an opening for water intake at a lower end, and as a result, the opening of the rotating body Since the peripheral edge lies almost horizontally (see FIG. 6), water flows into the rotating body from the tangential direction of the peripheral edge of the opening even if there is a time tag until the follow-up of the main body of the gas treatment device with respect to the water surface. It is possible to prevent the pumping from being interrupted due to the interruption of water.

  For the same reason as above, the rotating body has less resistance in the water due to the dome surface, and even if the water surface suddenly undulates or tilts, the mist generator body inadvertently tilts and the water in the cylinder is interrupted and pumping is interrupted It is possible to obtain an effect that is prevented.

  In the third aspect of the invention, by providing a cylindrical screen that rotates around the water sprinkling part, the water sprinkling part first crushes the water into a coarse mist and then scatters it into a finer mist with the screen. Scatter. As a result, it is not necessary to attempt to make the mist particle size finer at the stage of the sprinkling part, so the size of the slits and pores can be set to such an extent that water can pass through the outer peripheral wall of the sprinkling part well. It becomes possible, and a large amount of water can be used to generate mist.

The screen 16 is fixed to the end member concentrically with the rotating body. The water sprinkling part 12 and the screen 16 are concentrically arranged in a cylindrical shape. In this embodiment, the water sprinkling part 12 has a large number of slits 12S, but the screen 16 still has a large number of slits 16S. The one that has been drilled is used.

  Reference numeral 7 in the figure denotes a cavitation prevention plate that is suspended from a lower portion 10 of the rotating body 10 of the inner cylinder 3 in order to cancel out cavitation caused by the swirl of water caused by the rotation of the screw 15.

  The gas processing apparatus main body M having the above configuration is operated by being suspended in the water W stored in the water tank T installed in the vehicle. In this case, there is provided means for regulating the movement range of the gas processing apparatus main body suspended in the water tank so that the gas processing apparatus main body M does not move on the water and collide with the edge of the water tank T due to acceleration due to a change in traveling speed. . In this embodiment, the restricting means is formed by connecting several places on the circumferential side of the gas processing apparatus main body M to the edge of the water tank T by the coil spring C, but the restricting means is not limited to this. 1).

  In the present invention, the rotating body 10 of the mist generating unit 1 is rotated in the processing chamber R1, thereby pumping water W from below to above by the screw 15, and cylindrical sprinkling that rotates the pumped water W1 together with the rotating body. By colliding with and passing through the slit 12S of the part 12, the mist M1 is scattered as a mist M1, and further, the scattered mist M1 is collided and passed through the slit 16S of the cylindrical screen 16 disposed around the watering part. It is crushed into fine mist M2 and scattered (see FIG. 4). On the other hand, with the blower blade 5 rotating in the intake chamber R2 together with the rotating body 10, the inside of the processing chamber R1 is brought into a negative pressure state and the outside air is sucked from the outside air introduction hole 2A and introduced into the processing chamber, and the mist M2 The generated mist is brought into contact with the introduced outside air to form a mist atmosphere containing negative ions, and the mist atmosphere is discharged to the outside through the discharge hole 4A to form a heated mist atmosphere in the bathroom.

  FIG. 6 is a view showing a second embodiment of the vehicle gas treatment apparatus of the present invention. In this embodiment, the structure of the rotating body of the mist generating portion is different from that of the first embodiment. That is, the lower part of the rotating body 30 immersed in water is formed in a dome shape having an opening 31 for water intake at the lower end. The opening 31 is provided so that the periphery of the opening is in a state of being almost horizontal, that is, the dome surface is left at the periphery.
