Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a negative ion generator that generates negative ions in the air using the Leonard effect (waterfall effect).
[0002]
[Prior art]
When a water droplet breaks up in the air, more precisely, when a water droplet collides with a metal plate, which is a barrier, and splits, negative ions are generated in the nearby air, and the water droplets are equal in amount to positive ions. The phenomenon of obtaining an electric charge has long been known as the Leonard effect (Lenard's effect). This phenomenon is also called the waterfall effect because negative electricity exists in the air near the waterfall.
[0003]
A method of generating negative ions using the Leonard effect is described in, for example, Japanese Patent Publication No. 5-587555. In this method, fine water droplets are generated from water by a fine water droplet making machine, and at the same time, air is blown into the fine water droplets at a wind speed of 0.5 to 50 m / sec to form fine water droplet mixed air, and then the fine water droplet mixing is performed. By passing air through a separator, fine water droplets having a particle size of at least 1 μm are separated to form ultrafine water droplet mixed air, and negative ions are generated in 1.25 × 10 ⁹ or more in 1 m ^{3 of the} ultrafine water droplet mixed air. Is. In this preceding example, the fine water droplet making machine is a water splitting unit, and the separator is a gas-liquid separating unit. In the water splitting section, a device that ejects water at high pressure and collides with the impingement wall, a device that injects water onto a rotating disc and applies centrifugal force to the sprayed water to split it into fine water droplets, ultrasonic humidification A device that vibrates water and divides it into fine water droplets or a device that blows water onto a rotating impeller and smashes the water with an impeller to divide the water into fine water droplets is used. A separator is used.
[0004]
When using the above apparatus, fine water droplets generated in the water splitting section are blown, and the fine water droplets are separated from the air in a cyclone separator, which is a gas-liquid separation section, to extract air containing negative ions to the outside. it can.
[0005]
One of attempts to downsize the negative ion generator and use it as a home air cleaner is an air cleaner described in Japanese Utility Model Laid-Open No. 4-126717. As shown in FIG. 6, this air cleaner takes in air through a dust collecting filter device 32 composed of a plurality of filters by being sucked by a fan 31, and is injected from an injection nozzle 34 in a gas-liquid contact portion 33 having a cyclone structure. After ejecting fine water droplets to bring them into gas-liquid contact, they are sent to a droplet separator 36 having the same cyclone structure communicating through the communication port 35 to remove excess water, and then clean air is discharged from the air discharge port 37. The In the figure, 38 is a pump that pumps water to the injection nozzle 34, 39 is a water supply tank, and 40 is a water tank that contains the water to be injected. In terms of function, the gas-liquid contact portion is a “water splitting portion” referred to in the present invention when focusing on the generation of negative ions due to the Leonard effect, and the “droplet separation portion” is a “gas-liquid separation portion”. When an air cleaner is actually put into practical use for home use, a device has been sought because it is necessary to solve problems such as downsizing, ease of manufacture, and cost.
[0006]
[Problems to be solved by the invention]
By the way, since the negative ion generator (air purifier) uses water for generating negative ions and is in contact with the outside air while circulating water, solid components such as calcium contained in the water are present. The water splitting unit, gas-liquid separation unit, the inside of the water tank, and the pipes connecting each unit may be deposited, and atmospheric dust taken into the circulating water may accumulate on each unit.

A fixed amount of water is accommodated in the water supply tank 6, loaded in the main body case 7, and the main body case 7 is covered with a lid plate 17. The water in the water supply tank 6 flows out of the water supply tank 6 and is stored in the bottom portion of the negative ion generation chamber 19 that becomes the water tank 3.
[0022]
When the pump 4 is activated, the water in the water tank 3 is sucked from the water inlet 24 and is supplied to the injection nozzle 8 through the water outlet 25. The water is supplied from the nozzle holes 8 b provided in the jet nozzle 8 into the first cyclone cylinder 10. And collides with the wall 8c, further collides with the inner wall of the first cyclone cylinder 10 and breaks up into fine water droplets, generating negative ions in the air. On the other hand, when the blower 5 is started, outside air is sucked from the air inlet 22 at the bottom of the main body case 7 and then introduced into the air supply chamber 20, passes through the air inlet 13 from the air outlet 23, and enters the first cyclone cylinder 10. It is press-fitted into.
