The present invention relates to a decoration that generates negative ions using the Leonard effect.

The phenomenon of ionization of nearby air when water droplets split in relation to rain and other precipitations has long been known as the Leonard effect. Leonard generates ions in the surrounding air when the droplets collide with the metal plate, and the total charge amount of the split droplets is larger than the amount of electricity of the first droplet. The charge of ions generated in the air Experimentally found that the electric charges of the droplets increased by the totalization and fragmentation of the densities were equal, but afterwards, Simpson repeated Leonard's experiments, using a more precise device to make the droplets split in the air. It is confirmed that the same result as Leonard, that the ions generated in the air are negative ions of any water droplets, and that the same amount of positive charges as the ions generated when the water droplets split are obtained. It is reported. (See Harajima Yamada, Makoto Kawano, Iwanami Bookstore 1955 p26-27.)

The negative ion generated by ionization of air has deodorization, dust removal, antibacterial effect, and antistatic effect in addition to human and animal effects. In particular, the effects on humans and animals include mental sedation, hypnosis, fatigue prevention, fatigue recovery, analgesic, diuretic, bronchial asthma, chronic bronchitis, cold quenching effect of cold, refreshing effect, animal breeding performance. It is experimentally demonstrated that there is a chemical reaction, and an attempt to use an anion generating device in an air conditioning facility in order to take advantage of this action of anion is currently in progress. As a typical method of artificially generating negative ions, a method using a corona discharge has been known. This method entails cations in the amount and anion generated by corona discharge, and takes the anions outward. However, this method has a drawback that ozone, nitrogen oxides, etc., which are harmful to the human body, are generated as by-products. Advantage According to the Leonard effect, negative ions can be generated without the generation of harmful components only by the division of water droplets.

A method of generating anions using the Leonard effect is described, for example, in Japanese Patent Application Laid-Open No. 4-141179 (anion production method and apparatus thereof). The method described in the preceding example is a microdroplet manufacturing machine that generates microdroplets from water and at the same time blows air into the droplets with a wind speed of 0.5-50 m / sec to mix the droplets and then mix the droplets. will sikindaneun the air to at least a diameter (粒徑) 1㎛ mixed more seconds to remove the large fine water droplets fine droplets through the air separator, and the negative ions in the ultrafine droplets mixed air 1㎥ occurs more than 1.25 × 10 ^9.

According to such a prior art example, a high-pressure water is sprayed on a fine disc by using a rotating disc or vane to split water into fine droplets. In the preceding example, an example of using an ultrasonic humidifier in the manufacture of fine water droplets is also described, but the urine faithfully reproduces the Leonard effect of generating anion in the surrounding air when the energy is imparted and collided with a metal plate, thereby splitting into fine water droplets. I think.

On the other hand, a cyclone separator is used for the separator which carries out a gas-liquid separator. The cyclone separator is capable of separating gas-liquid at a level having a particle diameter of 1 μm by increasing the separation performance by increasing the wind speed. However, when the cyclone separator is used for the gas-liquid separator, the water flows on the inner wall of the body of the cyclone separator to divide into micro water droplets, and at the same time, it is possible to obtain micro water droplets and to separate the gas liquid. A strong centrifugal force can be applied to the water droplets to generate negative ions.

Nevertheless, because the cyclone separator separates the gas-liquid by centrifugal force action by the swirling flow of high-pressure airflow, it requires high energy for gas-liquid separation, requires a high-power blower, and cyclone for centrifugal force separation of the gas-liquid. The length of the body must be secured to some extent. This is a big limitation in miniaturizing the anion generator.

Clearly, the cyclone separator is excellent as gas-liquid separation and it is very good as a separator that separates water droplets from the gas to extract negative ions, but it becomes large and generates noise. Inserting a separator is not valid. Moreover, the droplets contained in the gas need to be removed, but gas-liquid separation is not necessarily by centrifugation.

An object of the present invention is to provide an anion generator that separates water droplets and fine droplets generated in the air without accelerating the cyclone separator in the separator, and promotes the separation to supply air containing a large amount of anions.

In order to achieve the above object, in the anion generating device according to the present invention, as an anion generating device having a water splitting part, a gas-liquid separator, a splitting accelerator, and a blower, a water splitting part, a gas-liquid separator, and a splitting accelerator The column is arranged in series along the flow direction of the gas fed from the outside, and the water dividing portion is formed at the front end of the flow path of the gas fed from the outside, and the water is separated, thereby separating the gas containing water droplets generated by the splitting. It is a part to be sent to the part, there is a nozzle and a partition, the nozzle is to eject the water in the water splitting section, the partition is to collide with the water ejected from the nozzle to split into water droplets, the gas-liquid separator is sent out from the water splitting section It is a part that receives gas and traps water droplets contained in the gas to separate and remove it from the gas, and the separation promotion part is gas sent out from the gas-liquid separation part. It is a part that promotes the breakdown of the fine droplets remaining in the gas by receiving a sieve, and there is a bypass in the gas flow path, which bypasses the expansion, contraction, and interference with the flowing gas, thereby re-spliting the fine droplets contained in the gas. The blower sucks outside air, introduces it into the water splitting section, and delivers a gas containing anion generated by the cleavage of water into the outside air.

In addition, the blower is provided on the downstream side of the splitting accelerator to draw the outside air by applying a suction force to the splitting portion.

In addition, the water splitting part has two or more partitions, and the partitions are arranged in front and rear along the gas flow direction in a part of the gas flow path to form an angle with each other, and the nozzles are installed to face each partition. In addition, the gas-liquid separator is a pair of partition walls which have been separated by a predetermined distance in the gas flow path between the water splitting part and the splitting facilitating part, and both partition walls form a bypass of the gas flowing into the splitting facilitating part from the water splitting part. To form a collision surface.

In addition, the splitting accelerator has two or more obstruction plates, and each of the obstruction plates runs away from the opposing wall with an angle toward the upstream side of the gas flow path in the gas flow path in the splitting accelerator.

In addition, the water splitting part, the gas-liquid separating part, and the splitting promoting part are formed in a casing of the rectangular parallelepiped to form one unit, and two or more units are arranged in parallel.

In addition, two or more units are arranged side by side in the vertical and horizontal directions.

In the present invention, the gas is introduced into the water fission portion of the casing at high pressure to eject water from the nozzle in the gas. The water collides with the partitions and splits to generate negative ions in the air. The gas passing through the water splitter is introduced into the gas-liquid separator so that the gas collides with the partition wall of the gas-liquid separator, and most of the water droplets contained in the gas are directed to the partition wall and removed from the flow path of the gas. Fine droplets remain in the gas flowing out of the gas-liquid separation part and introduced into the splitting accelerator, and in the splitting accelerator, the gas passes through the gas flow path formed by the runoff of the baffle plate and is later discharged to the outside air. During flow in the unit, the gas is tightened between passages between the open ends of the front and rear baffle plates, and then the gas expands in the pockets formed by the inclination of the baffle plate, resulting in repeated expansion, contraction or interference. This further promotes the cleavage of the fine water droplets remaining in the gas and generates a large amount of negative ions in the air. Gases containing anions are pumped into the outside air.

In the present invention, the blower is provided at the front end of the water splitting unit or the rear end of the splitting accelerator. When a blower is installed at the front end of the water splitting section, the apparatus is "gas pushed" for the apparatus, and a "gas suction type" is installed when the blower is installed at the rear stage of the splitting accelerator. In any case, there is no big mistake as a function of the blower, but in the case of the `` gas suction type, '' the gas is hit by the blade of the blower immediately before it flows to the outside air, or agitated to increase the generation efficiency of negative ions due to the Leonard effect. .

Embodiments of the present invention will be described below with reference to the drawings.

1 shows the basic configuration of the present invention. In FIG. 1, the apparatus of the present invention is a combination of a water splitting part 1 and a gas-liquid separating part 2, a splitting accelerator 3, a water tank 22, a pump 23, and a blower 4. Will be.

The water splitting section 1, the gas-liquid separating section 2, and the splitting promoting section 3 are placed in the casing 5 as a unit A. The casing 5 has a gaseous outlet 7 at the other end of the gas inlet 6 at one end of the long side in a long rectangular parallelepiped. The blower 4 is combined at the rear end of the gas outlet 7 of the casing 5 in the case of the embodiment. The pump 23 is provided separately from the casing 5, and the water tank 22 is attached to the casing 5, but can be combined as a card ridge.

The water dividing unit 1 is a portion which generates water by splitting water. In the water splitting section 1, there is a gas flow path leading from the gas inlet 6 to the gas-liquid separator 2, and a partition 8 and a nozzle 9 are provided in the gas flow path. The nozzle 9 sprays water, and the partition 8 is a collision surface of the sprayed water. The partitions 8 are disposed at an angle to each other with respect to the longitudinal direction of the casing 5 at regular intervals before and after, and are inclined in a direction different from the partition 8 at the front end and the partition 8 at the rear end and are fed from the outside. It also serves as a collision surface for changing the flow direction of the gas.

In the embodiment, the front partition 8 is provided with nozzles 9 facing each other on both sides thereof, and the rear partition 8 is provided with a nozzle 9 facing only one surface thereof. The number of partitions and the location of installation are not limited, and it is free to install three or more stages in front and back to a degree that does not increase the static pressure in the gas flow path. Although the flow direction of the gas is set on its own by the arrangement of the partitions 8 at each stage and the setting of mutual relation positions, the partitions 8 change the flow direction of all the gases received in the water splitting part 1. no. Some of the gas introduced into the water dividing unit 1 is laminar and may reach the gas-liquid separator 2 as it is.

The gas-liquid separator 2 is a partition 10 which ran in the gas flow path between the water splitting part 1 and the splitting accelerator 3.

In the embodiment, the partitions 10 are paired, and each of the partitions 10, 10 is removed at right angles from the opposite inner wall of the casing 5, out of the positions back and forth, respectively. By overlapping, the gas detour is formed in the gas flow path from the water splitting part 1 to the splitting promoting part 3. The partition 10 is a collision surface of the gas. The gas is repeatedly impinged on the inner wall surface of the partition wall 10 while the gas flows through the bypass, so that most of the moisture contained in the gas is attracted to the plate surface of the partition wall 10. In the water splitter 1, the drain drain 11 is open at the bottom, and is stacked in multiple stages as a unit to receive the drain drained from the drain drain of the upper unit and drain it to the lower unit ( 12 penetrates the casing 5 up and down.

The splitting accelerator 3 receives the gas flowing out from the gas-liquid separator 2 and promotes the splitting of the fine water droplets remaining in the gas after the gas-liquid separation. In the splitting accelerator 3, the obstruction plates 13 and 13 run away from the opposing wall along the longitudinal direction of the casing 5 so as to face each other and form an upper circuit in the gas flow path.

The obstruction plate 13 is formed at an angle toward the upstream side with respect to the flow direction of the gas to form the pocket 14 in the flow path of the gas. The gas introduced into the splitting facilitator 3 is clamped between the open ends of the opposite baffles 13 and 13 and enters and expands into the pockets 14 of the respective baffles so as to repeat and interfere with the expansion and contraction. This promotes the splitting of fine water droplets contained in the gas and generates a large amount of anions.

The blower 4 applies a suction force to the gas inlet 6 of the casing 5.

Air sucked into the gas inlet 6 by the operation of the blower 4 passes through the water splitter 1, the gas-liquid separator 2, the splitter 3, and the outlet 7 of the casing 5. Air flowing out from the) and the negative ions are sent to the external air via the blower (4). In the blower 4, fine droplets remaining in the gas are beaten by the rotary blades of the blower 4, and the division proceeds again, thereby greatly contributing to the generation of negative ions. 2 shows a practical example of an anion generator incorporating the apparatus of the present invention in FIGS. The gas 15 has an outside air inlet 16 at one end of the transversely long side and an anion outlet 17 at the other end thereof, and is along the gas flow path formed between the outside air inlet 16 and the anion outlet 17. A filter 18, an air rectifying plate 19, a cooling coil 20, a heating coil 21 and a blower 4 are installed in this order, and the gas inlet port 1 of the water splitting section 1 of the unit A is installed. 6) Place the gas outlet 7 of the splitting accelerator 3 on the side of the air rectifying plate 19 on the side of the blower 4 to load the unit A between the cooling coil 20 and the blower 4. . The water tank 22 is a water tank containing water supplied into the water splitter 1, and the water in the water tank 22 is pumped up by the pump 23 and supplied to the nozzle 9 in the water splitter 1 so as to supply a nozzle. By (9), it ejects toward the partition 8.

2-4 show 10 units A, A... Side by side in a row and decorate again in the upper and lower two-tier is an example decorated in the body (15). Depending on the amount of negative ions generated and the size of the air capacity, the number of units to be decorated increases.

The cooling coil 20 is for cooling the delivery gas, and the heating coil 21 is for heating the delivery gas. Cooling coil 20 or heating coil 21 is selectively operated to adjust the temperature and humidity of the gas discharged from unit (A).

When the blower 4 is driven, the suction force acts on the outside air intake 16 so that outside air is sucked into the gas 15, the outside air is first removed by the filter 18, and then the air rectifying plate 19 Air containing the negative ions rectified in each unit (A) and sent out through each unit (A) is cooled and warmed with a cooling coil (20) or a heating coil (21) to a desired temperature and humidity. It is adjusted and exhausted from outside air from the negative ion outlet 17.

Unit A, A... When the top and bottom are arranged in two stages, the cylinder 12 penetrating the casing 5 of the lower unit A up and down becomes the drain of the upper unit A, and the drain in the upper unit A is the lower unit. (A) returns to the bucket 22 through the bucket 12. The arrangement of the unit A is not limited to the tailoring of the embodiment, but can be finished by arranging the columns in arbitrary numbers on the left and right sides.

According to the present invention as described above, while transporting the anion generated by the cleavage of the water by air force, most of the droplets generated by the cleavage of the water are promoted in the flow of the gas to separate and remove it from the gas, and the cleavage of the droplets remaining in the gas is removed. By accelerating, it is possible to take out humid air containing a large amount of anions into the air without causing noise in a relatively short distance.

According to the present invention, the water splitting section, the gas-liquid separation section, and the splitting promotion section are sequentially formed in the longitudinal direction of the casing, and a bypass is formed in the gas flow path substantially in each section, without causing excessive pressure loss in the gas flow. Negative ions can be generated.In particular, by using the blower as a `` suction type '' for the generation of fluid gas, the anion-containing air is stirred and beaten again with the blade of the blower just before flowing out of the air. The amount of generation is further increased.

In the water splitting section, a partition is installed by blocking a part of the gas flow path, so that the turbulence and vortices are generated by interfering between the gas colliding with the partition and the gas passing through the partition, and the flow of water injected into the turbulence. It is thought that water cleavage advances by winding up.

In the gas-liquid separation section, the gas flows in a direction perpendicular to the gap between the pair of partition walls, and the gas flows repeatedly while the gas collides with the inner surface of the partition walls and the casing so that most of the water droplets contained in the gas are effective. Is removed.

In the splitting accelerator, the gas is repeatedly flowed between the open ends of the left and right obstruction plates at an angle from the opposing wall of the casing, and in the pockets of the obstruction plates. Can be added to the fine droplets contained in the gas.

In the present invention, the water splitting unit, the gas-liquid separation unit, and the splitting promotion unit are packaged in a casing to unitize the unit, and thus, one unit or two or more units can be arbitrarily decorated to decorate an anion generator having a desired capacity.

The present invention does not require a large output blower as in the case of using a cyclone separator for gas-liquid separation, and can be miniaturized with low noise. Therefore, the present invention is very suitable for use as an anion generator of an indoor installation type that serves as an air conditioner.
