Description

  The present invention is an air purifier, which is provided with an air inflow portion, an air transfer device, a liquid reservoir for containing a cleaning liquid, and a rotating complex driven by a motor. In which the rotation axis is substantially perpendicular to the liquid mirror surface of the cleaning liquid and the rotating complex has one centrifugal disc and is at least partially surrounded by a baffle element .

  Humans are exposed to increasing air pollution. Airborne particulates, dust, pollen, bacteria or gaseous pollutants load and depress human respiratory organs. As a result, it is not uncommon to develop chronic allergies or even life-threatening illnesses.

  In order to reduce the effects of air pollution on humans, air purifiers are known, but these air purifiers remove harmful components from the inhaled air and additionally provide moisture. This is because moderate moisture in the air can improve human health.

  For air purification and humidification, air purifiers use a cleaning solution, which is water in the simplest case. In some cases, additives and / or aroma substances are added to the purification liquid to give the purified air a special quality.

  A variety of structural types of air purifiers are known in the prior art, and these air purifiers have a variety of physical effects for air purification and humidification and for the transfer of air and cleaning fluids. Is used.

  The heart of a known air cleaner based on Japanese Patent Application Laid-Open No. 7-243777 is a group of structures that can be referred to as a rotating complex. This rotating complex consists of a plurality of components that perform different partial functions of the air cleaner. These components are arranged along one common axis of rotation and are rotated by a motor. The rotation axis is arranged perpendicular to the liquid mirror surface of the cleaning liquid stored by the liquid reservoir.

  The main components of the rotating complex of the above publication are a centrifugal disk, an air conveying device in the form of an axial fan, and a liquid conveying device, which consists of a screw and a double-walled helical cylinder. ing. The rotating complex is almost completely surrounded by a fog chamber. The liquid transport device transports the cleaning liquid from the liquid reservoir along the rotation axis toward the centrifugal disk disposed on the liquid mirror surface. The centrifugal disk is then wetted by the cleaning liquid, and the cleaning liquid is blown off by centrifugal force from this centrifugal disk to the baffle element surrounding the rotating complex in the region of the centrifugal disk. As a result, the cleaning liquid is atomized finely. An axial fan produces an air flow that carries the atomized atmosphere in the fog chamber from the air cleaner to the surroundings.

  The effectiveness of this known air cleaner is unsatisfactory. A significant portion of the ambient air that the air cleaner draws through its inlet opening flows through the machine without being purified. That is, in this case, a considerable portion of the ambient air flows too much by the mist-like atmosphere that flows out of the fog chamber. This is clear hydrodynamically. This is because the incoming air is not forced through the fog chamber. Rather, in this case, a low resistance path is formed in the fog chamber that extends alongside the moist and heavy air. Therefore, effective air purification is not possible with the known configuration. At best, the mist-like atmosphere that flows out of a known air cleaner mixes with the surrounding air and provides moisture to the surrounding air.

  It is therefore an object of the present invention to provide an air cleaner that ensures effective purification of ambient air.

  In order to solve this problem, in the configuration of the present invention, in the air cleaner of the type described at the beginning, the rotating complex has a plurality of risers and a plurality of centrifugal discs in addition to the centrifugal discs. These centrifugal discs are positioned substantially parallel and spaced apart from each other, have a vent opening at the center of rotation, and the riser pipe extends substantially parallel to the rotation axis. It penetrates the disc, has an outflow opening in the region of the upper side of the centrifugal disc, and is in contact with the cleaning solution at the end directed to the liquid reservoir.

  The advantage of this air cleaner is that the air to be purified is forced to flow through a mist-like atmosphere between the individual centrifugal discs. This ensures a particularly powerful air purification and humidification.

  In order to improve the filling of the riser, in another configuration of the invention, the rotating complex has a hopper-like supply device with an inflow part and a supply tank, at least the supply tank on the axis of rotation. Are divided into a plurality of chambers along which the end of the riser tube directed towards the liquid reservoir is reached.

  Such a supply device generates a sufficient liquid pressure in the cleaning liquid even when the angular velocity of the rotating complex is small, and as a result, a liquid column having a required height is formed in the ascending pipe.

  The cleaning liquid absorbs air pollutants, which of course contaminates the cleaning liquid itself. In order to extend the useful life of the cleaning liquid flowing in the circuit and to improve the dirt absorption capacity just before atomization, in another configuration of the invention, a filter element surrounding the end of the riser tube directed to the liquid reservoir is provided. Is provided. Instead of surrounding the end of the riser, it is also possible for the filter element to surround the supply device.

  In order to improve the efficiency of the air cleaner, it is desirable to avoid the mixing of the inflow air to be purified and the purified outflow air inside the air cleaner. Therefore, in another advantageous configuration of the present invention, an inflow air guide portion is provided, the inflow air guide portion isolates the flow of the inflow air inside the air cleaner, and the air inflow portion is separated from the air inflow portion. It extends to the centrifugal disc located closest to the part.

  Next, an embodiment of an air cleaner according to the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the principle of an air cleaner,
2 is a cross-sectional view taken along line AA in FIG.
3 is a cross-sectional view taken along line BB in FIG.

  The air purifier is generally designated 0. The air cleaner 0 has a housing 1, and the housing 1 includes a hood 2 and a covering 3. The covering 3 has a liquid reservoir 4 that stores the cleaning liquid 5. The heart of the air cleaner 0 is a rotating complex 6, and the rotation axis 7 of the rotating complex 6 is disposed perpendicular to the liquid mirror surface 8 of the cleaning liquid 5.

  The main components of the rotating complex 6 are a plurality of centrifugal discs 9, three ascending pipes 10, and a hopper-shaped supply device 11. The riser 10 is stabilized by the holding body 12. The motor 13 rotates the rotary composite 6. The rotating complex 6 is surrounded in the region of the centrifugal disc 9 by a baffle element 14 that acts as a baffle plate.

  An air conveyance device 15 is disposed on the rotating complex 6, and the air conveyance device 15 sucks inflow air 16 to be purified through an air inflow portion 17 provided in the hood 2. The air conveying device 15 may have a unique driving device, or may be driven together by the motor 13 of the rotating complex 6. An inflow air guide portion 19 extends between the air inflow portion 17 and the centrifugal disk 18 located closest to the air inflow portion 17. The inflow air guide portion 19 is an air purifier. The inflow air 16 to be purified is isolated inside the zero.

  The hopper-shaped supply device 11 has an inflow portion 20 and a supply tank 21. The guide vanes 22 divide the supply device 11 into three chambers 23 along its longitudinal axis 7.

  The inflow part 20 is located below the liquid mirror surface 8 of the purification liquid 5, and the supply device 11 is surrounded by the filter element 24 there. The rising pipe 10 is an end portion directed toward the liquid reservoir 4 and enters each chamber 23 inside the supply tank 21.

  As the rotational speed of the rotating complex 6 increases, a damming pressure is generated in front of the guide vanes 22, and this damming pressure pushes the cleaning liquid 5 into the ascending pipe 10 through the supply tank 21. At the operating speed, the liquid column in the ascending pipe 10 reaches the centrifugal disk 18 closest to the air inflow portion 17.

  The centrifugal disk 9 has a ventilation opening 25 at the center of rotation. Around the ventilation opening 25, three rising pipes 10 are arranged on a common radius, that is, on the same circumference.

  The ascending tube 10 is a simple tube having a circular cross section that penetrates the centrifugal disc 9 and holds the centrifugal disc 9.

  In the region of the surface of the centrifugal disk 9, that is, in the region where the virtual plane extending through the surface of the centrifugal disk 9 intersects the longitudinal axis of the upward tube 10, the upward tube 10 has an outflow opening 26. These outlet openings 26 are preferably directed radially outward.

  The cleaning liquid 5 flows out of the ascending pipe 10 through these outflow openings 26 and wets the surface of the centrifugal disk 9. Then, the purification liquid 5 is blown off from the centrifugal disk 9 toward the baffle element 14 by centrifugal force, whereby the purification liquid 5 is aerosolized.

  Incoming air 16 is blown from the air conveying device 15 into the vent opening 25 of the centrifugal disk 9. The inflowing air 16 then moves radially toward the baffle element 14 along with the centrifugally accelerated cleaning liquid 5 and then moves downward along the baffle element 14 toward the liquid reservoir 4 and is purified. As a result, the baffle element 14 and the cover 3 are moved upward again as the outflow air 27, and finally flow out from the air cleaner 0 through the air outflow portion 28 between the hood 2 and the cover 3.

  By conducting forced air guidance through a mist-like atmosphere, the air can be thoroughly purified. The inflow air guide part 19 further prevents the inflow air 16 and the outflow air 27 from mixing inside the air cleaner 0. The cleaning liquid 5 is filtered by the filter element 24 in front of the inlet to the supply device 11 which increases the damming pressure.

It is a figure which shows the principle of an air cleaner. It is sectional drawing along the AA line of FIG. It is sectional drawing along the BB line of FIG.
