The present invention relates to a nozzle structure used for an anion generation / humidity control air cleaner that generates anions and moisture by using the water sand and the collision principle. Specifically, the present invention dramatically reduces noise generated during water sand and collision. The present invention relates to a nozzle structure for anion generation / humidity control air purifier, which can generate finer and more uniform moisture, and also improves anion generation efficiency and dust collection efficiency.

The air we breathe is inseparable from our health and has many direct and indirect effects.In particular, the air in modern urban areas, which are heavily polluted by automobile exhaust, are the cause of various diseases including respiratory diseases. It can also be.

Such polluted air in the city contains various pollutants such as nitrogen oxides, sulfur oxides, ozone, various oxidants, and fine dusts. As the risks of these pollutants are widely recognized, it has recently been spotlighted as an essential household appliance. It is an air purifier.

On the other hand, ions are generally distributed in cation 4 to anion 5 in the deep mountain or rural air, which is usually fresh air. It is also called air vitamin because it has various effects useful for the human body such as cell activation, resistance increase, pain relief, autonomic nervous system regulation, mental stability, pulmonary function, analgesic and allergic improvement. .

However, it is almost impossible for modern people to live a healthy life in the air with balanced cation / anion ratios due to the effects of cations generated from various pollutants such as air pollutants and household appliances that are inevitably present in the living space. In this sense, the negative ion generating function can be said to be as important as the air cleaning function to remove fine dust or bacteria. For this reason, it is the negative ion generating device that has recently been spotlighted as an essential household appliance with an air cleaner.

The present applicant responds to the tide of the air cleaner and the negative ion generating device is increasing in the real life in this way, in the Republic of Korea Utility Model Registration Application No. 2003-6081, as shown in Fig. Water inlet pipe 110, rotary spray nozzle 130 for rotating spraying the circulation water, impingement plate 140 for colliding the injected circulating water, magnet 150 for increasing the amount of negative ions generated, air inlet for introducing air ( 160 and anion / humidification chamber 100 including air outlet 170; A wet dust collecting chamber 200 including an inlet 210 through which anion / moisture-containing air is introduced, and anion / humidity discharge tube 220 for discharging the anion / humid-containing air to a room outside the air cleaner; A connection passage 300 for transferring the anion / humid-containing air generated in the anion / humid generating chamber 100 to the wet dust collecting chamber 200; A blowing duct 400 for guiding the air provided by the blowing fan to the blowing hole 160; A circulation water storage tank 500 for storing the circulation water; An apparatus chamber 600 in which a blowing fan F, a circulation pump P, and a drain tank D are incorporated; It has been filed for an anion generation / humidity control air cleaner, including a case 700 provided with a control panel C and an inlet 710.

In fact, it is common to use a method of purifying contaminated air using a filter. In addition, in the case of an anion generator, it is preferable to use an anion generating effect by electrolysis of electrodes, ultrasonic waves, photocatalysts, ultraviolet rays, and the like. In general, the two patents and utility model registration applications by the present applicant can be characterized as using water for both air purification and anion generation, unlike this method.

This is a portion for first colliding the water sprayed from the injection hole before colliding with the plate 41, so that the circulating water impinged on the collision rod 42, the collision hole 43, as shown in FIG. Due to the nature of the spheres diffracting the flow of fluid, the water impinges on the plate 41 again while forming a water-shaped water film.

Here, the lower diameter of the solid water film generated by the impact on the circulating water should not be beyond the diameter of the plate 41, the diameter of the injection cap 30 of the injection hole is 1-15mm, which is the range of the diameter of the injection nozzle commonly used At this time, in the present invention using the plate 41 in the range of 10-100mm diameter, the diameter of a suitable impact hole 43 for forming a solid water film of this size is 1-20mm, the impact hole 43 and the The proper distance from the injection cap 30 injection hole is 0.50-1.50 mm, preferably 0.65-1.00 mm.

This is to prevent the discharge from being included in the moisture, and to reduce the angle between the colliding water and the plate so that most of the circulating water collided can flow down uniformly along the upper surface of the plate 41.

In addition, in the nozzle structure of the present invention, the horizontal cross section of the inclined surface formed on the upper surface of the impingement plate 40 and the plate 41 forms a regular polygon having a number of sides of three or more, and when the horizontal cross section forms a regular polygon of three or more sides of the plate 41, The upper surface is to form three or more flat inclined surfaces, such as the water also flows along the impact plate after the collision by the inclined structure is divided in the fan-shaped arc line, that is, the end of the plate 41 and scattered with each other It aims to increase dust collection efficiency by preventing many noises from colliding at the same time and scattering a lot of ultra-fine droplets horizontally.

Nozzle cap 50 consisting of a fastening means 54 for fastening by fixing the 50 to the circulation water inlet pipe is further configured integrally with the support plate 44 of the impingement plate 40.

The nozzle cap 50 is further configured and used to prevent the nozzle from being deformed or leaked by being flown by water pressure during use for a long time after the injection nozzle 20 is fastened to the circulating water inlet pipe P. .

The nozzle structure for the anion generation / humidity control air purifier of the present invention configured as described above, when the nozzle cap 50 is used as an example, firstly, the nozzle receiving rib 10 on the outer wall of the circulating water inlet pipe (P). After accommodating and fastening the fastener 21 of the injection nozzle 20, the injection cap 30 is fastened to the injection cap 30 fastening means of the injection nozzle 20 to complete the nozzle structure for injection, and then The coupling is completed by covering the nozzle cap 50 so that the rib (not shown) formed in the circulating water inlet pipe P is accommodated in the slit 53 again, as shown in FIG. When used in a humidity control air purifier, it is common to use a plurality of circulation water inlet pipes (P).

Next, the operation process of the nozzle structure for anion generation / humidity control air cleaner of the present invention configured as described above is as follows.

First, the circulating water introduced into the injection nozzle 20 from the circulating water inlet pipe P is injected into the injection cap 30 through the injection hole.

The sprayed water collides with the bottom surface of the spray cap 30 by the spray pressure, and the collided water is mixed vigorously while forming a vortex.

In this process, the circulating water undergoes two or more anion generation processes. First, when the water is sprayed by the spray nozzle 20, the water with the increased internal energy is sprayed at an angle of 90 ° while being rotated inside the nozzle and the spray cap 30. Anion is first generated by the collision energy by colliding with the bottom surface, and then anion is secondarily generated due to internal energy increase while forming a vortex inside the injection cap 30 after the collision.

Next, the collision and mixed water in the injection cap 30, as shown in Figure 5, after impinging on the collision hole 43 by being injected through the injection cap 30 injection hole, the fine droplets of the solid shape The water film forms a water film and is scattered in the direction of the plate 41 so as to collide with the plate 41 again. At this time, the circulating water undergoes an anion generating process once again by the collision process. At the moment when it scatters in shape and when it hits the plate 41 and splits at the distal end and scatters horizontally, the liquid spreads widely and the contact area with the air is widened, thereby releasing anions and moisture.

The nozzle structure for the anion generation / humidity control air cleaner according to the present invention constituted as described above is primarily collided and mixed in the cap inside which the water sprayed by the spray nozzle 20 is sealed, and the spray cap 30 is separated. The water sprayed again by the hole is collided and scattered to the collision plate 43 and the collision hole 43 secondly, and the tripled water scattered after the collision to the collision hole 43 again collides with the plate 41. The injection / collision structure not only dramatically improves the anion generation efficiency, but also allows the collided water to be uniformly scattered into a solid shape by using the principle that the flow of the fluid is diffracted when it meets a sphere. Reduces the angle of collision and forms three or more inclined surfaces, respectively, on the upper surface of the plate 41 protruding obliquely to the center so that the collided water can flow evenly, and at the same time, it is evenly split at the distal end. By using the principle of scattering, it prevents large droplets from being discharged by irregular scattering and improves dust collection efficiency. Above all, the biggest problem of anion generation / humidity control air purifier using water It was possible to drastically reduce the noise that could be said.

In addition, the nozzle structure of the present invention is composed of a separate structure that is easily assembled with a general rotary spray nozzle and a simple configuration of the injection cap and the impingement plate, so that the structure is simple, easy to configure and maintain, and low cost It also has advantages.

By the completion of the present invention, the noise problem, which is the biggest technical problem of the anion generation / humidity control air purifier using water, is drastically improved, and the emission is reduced by greatly reducing the generation amount of the relatively large particle sized splash water generated after the collision. It is possible to provide a nozzle structure for anion generation / humidity control air cleaner using water, which can not only form the moisture to be fine and uniformly, but also greatly improve the amount and efficiency of anion generation compared to the existing nozzle structure. .
