Description

Humidifier with germicidal light emitting diode {Humidifier having sterilizing LED}

The present invention relates to a sterilizing humidifier, and more particularly, to a humidifier that generates moisture by sterilizing water in a humidification tank using an ultraviolet-light emitting diode (UV-LED).

In general, humidifiers that artificially generate moisture are used in dryers such as winter. Such a humidifier is divided into an ultrasonic humidifier, a heated humidifier, and a complex humidifier in which the humidifier is mixed according to the humidification method.

The ultrasonic humidifier sprays fine water particles by vibrating the water in the humidification tank with ultrasonic waves, and there is a disadvantage in that the amount of humidification sprayed is large but the water in the tank is not sterilized. When using a humidifier that does not have a sterilizing effect at all, there is a problem that various bacteria inhabiting water are delivered to the alveoli of the human body in water particles to cause pneumonia or allergic diseases.

Heated humidifier spontaneously sprays the water vapor generated by heating water in the humidification tank, and it is possible to sterilize bacteria in the water by heating water in the humidification tank using a heater or electrode. There are disadvantages. In addition, even a heated humidifier does not boil the water in the humidification tank to 100 ?? to make steam, there is a problem that can not expect a perfect sterilization effect.

In order to solve this problem, a humidifier in which a UV lamp is built in a humidifying tank has been devised, but such a conventional sterilizing humidifier simply installs an ultraviolet mercury lamp on an inner wall surface of a humidifying tank. Although the water particles are sufficiently sterilized in the vicinity of the ultraviolet mercury lamp, there is a problem that the sterilization treatment is not sufficiently performed at a point far from the ultraviolet mercury lamp.

In addition, when a large number of ultraviolet mercury lamps are installed in order to evenly sterilize the water in the humidifying tank, the size of the entire humidifier increases due to the size of the ultraviolet mercury lamp, and a large amount of power is consumed to emit the ultraviolet mercury lamp. If you want to use a long time there were many problems.

In addition, in the case of a conventional sterilizing humidifier using an ultraviolet mercury lamp, there was a disadvantage that the ultraviolet mercury lamp may be damaged by an external impact.

The present invention has been made to solve the above problems, it is possible to sterilize the water inside the humidification tank evenly using less power, the internal configuration is simple, the total volume is not greatly increased, damage by external impact It is an object to provide a humidifier that is configured to reduce concerns.

Sterilizing humidifier according to the present invention for achieving the above object is a humidification tank formed to contain a certain amount of water, a vibrator for vaporizing the water of the humidification tank, and the water of the humidification tank to sterilize the water of the humidification tank. And at least one ultraviolet light emitting diode that emits ultraviolet light toward the light source.

In addition, the sterilizing humidifier according to the present invention, the photocatalyst filter coated with a photocatalytic material is coupled to the inside of the humidifying tank in order to improve the sterilizing power of the ultraviolet light emitted from the ultraviolet light emitting diode. At this time, the photocatalyst filter is formed in a mesh shape so that ultraviolet rays of the ultraviolet light emitting diode can be transmitted, and the photocatalyst material is any one of TiO 2 , ZnO, CdS, ZrO 2 , SnO 2 , V 2 O 2 , WO 3, and SrTiO 3 . It is selected as a substance.

In addition, a diode cover may be further provided between the ultraviolet light emitting diode and the humidifying bath so as not to directly contact the ultraviolet light emitting diode with water or steam in the humidifying bath.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the sterilizing humidifier according to the present invention.

Figure 1a is an exploded view of the sterilizing humidifier according to the present invention, Figure 1b shows a bottom portion of the storage tank applied to the present invention.

It includes a storage tank 200 for supplying the water stored therein to the main body 100, and an ultraviolet light emitting diode 300 for sterilizing the water vaporized in the main body 100.

The main body 100 is formed with a concave humidification tank 110 so as to contain a predetermined amount of water at the upper end, and is coupled to the bottom surface of the humidification tank 110 to vaporize the water contained in the humidification tank 110. A vibrator 120 is provided, and a switch 140 for applying power and operating the vibrator 120 is provided on an outer surface thereof. In the present embodiment, the vibrator 120 is applied to the ultrasonic vibrator to amplify and vaporize the internal energy of the water contained in the humidification tank 110 by vibrating by the ultrasonic signal generated in the electronic circuit. Since the main body 100 having such a structure is the same as the main body applied to the conventional ultrasonic humidifier, a detailed description thereof will be omitted.

The storage tank 200 has a diode mounting portion 202 which is formed to be concave upward in a portion corresponding to the humidification tank 110, and the ultraviolet light emitting diode 300 is coupled to the upper side of the diode mounting portion 202. .

In addition, the humidifier tank 200, when seated on the stopper seating portion 130 formed on the upper surface of the main body 100, the stopper 210 is configured to supply a predetermined amount of water stored therein to the main body 100 And a spray guide tube 220 through which the spray guide hole 222 penetrates the inside so that the water vaporized by the vibrator 120 may be ejected to the outside, and the steam setting the direction of the steam ejected to the outside. A spray cover 230 is provided.

The diode cover 400 is further provided below the ultraviolet light emitting diode 300 such that water vaporized from the humidifying water tank 110 does not directly contact the ultraviolet light emitting diode 300. At this time, the diode cover 400 is formed in the cover hole 402 of the shape that can penetrate the spray guide tube 200 therein, made of a transparent material so that the ultraviolet light emitted from the ultraviolet light emitting diode 300 can be transmitted through Is preferred.

The ultraviolet light emitting diodes 300 applied to the present invention are configured to emit ultraviolet rays having a wavelength of 200 to 400 nm like conventional ultraviolet light emitting diodes. The ultraviolet rays having a wavelength of 200 to 300 nm have a sterilizing function while the wavelength is 300 nm. If it exceeds the sterilization action is reduced.

Therefore, the sterilizing humidifier according to the present invention includes a filter member 510 coated with a photocatalyst material to increase sterilization when ultraviolet rays having a wavelength of 300 nm or more are irradiated from the ultraviolet light emitting diode 300. The photocatalyst filter 500 is further provided to be coupled to the upper portion of the humidification tank (110).

Principle of sterilization by photocatalyst is similar to photosynthesis that plants chlorophyll receives ultraviolet light which is light energy and converts carbon dioxide into oxygen. As sterilization using an oxidizing power, such sterilization is a well-known technique, so a detailed description thereof will be omitted.

In the photocatalyst filter 500 applied to the present invention, a filter hole 502 is formed therein so that water in the humidifying tank 110 can be smoothly passed through, and the filter member 510 is formed in the ultraviolet light emitting diode 300. Ultraviolet light emitted is formed in a mesh shape so that the active oxygen generated by the photocatalytic material can be vented. In addition, the photocatalyst material coated on the filter member 510 includes titanium oxide (TiO 2 ), zinc oxide (ZnO), cadmium sulfide (CdS), zirconium oxide (ZrO 2 ), tin oxide (SnO 2 ), and vanadium oxide (V). 2 O 2 ), tungsten trioxide (WO 3 ) and strontium titanate (SrTiO 3 ) can be selected from among them, which are optically active, photocorrosive, biologically and chemically inert, and economically economical. It is also preferable to coat the filter member 510 with inexpensive titanium oxide.

As shown in FIG. 3, the sterilizing humidifier according to the present invention may have an internal structure changed such that the ultraviolet light emitting diode 300 is introduced into and coupled to the diode cover 400. When the UV light emitting diodes 300 are coupled to the inside of the diode cover 400 as described above, since the UV light emitting diodes 300 are fixed by the diode cover 400, there is less fear of damage due to external impact. There is an advantage.

At this time, when the ultraviolet light emitting diode 300 is applied as a chip-shaped ultraviolet light emitting diode, not only the size of the ultraviolet light emitting diode 400 itself is reduced, but also the diode cover 400 is thinner than the embodiment shown in FIG. 3. Since it can be manufactured, it becomes easier to miniaturize a product.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment and should be interpreted by the attached claim.

In particular, in the present embodiment, the UV light emitting diodes 300 and the photocatalyst filter 500 are described by applying an ultrasonic humidifier, but the configuration of the sterilizing humidifier according to the present invention is not limited to the ultrasonic humidifier but may be applied to a heated and complex humidifier. .
