Description

Bubbling-type antibacterial humidifier {BUBBLE-GENERATING HUMIDIFIER HAVING ANTIMICROBIAL EFFECT}

The present invention relates to a bubble-generating antibacterial humidifier. In more detail, unlike a general humidifier, a gas of a certain composition is provided so that bubbles are generated in the water to be humidified to increase the effect of humidification by expanding the specific surface area of the water to be humidified, and to prevent contamination of water remaining in the water tank. . Another object of the present invention is to provide an antibacterial power of additionally humidified water.

Since dry air irritates the respiratory mucosa, roughens the skin, and causes itching, various driving type humidifiers are used to control indoor humidity. In particular, for modern people, where indoor life is becoming more common, humidifiers for controlling indoor humidity have been distributed and used in various spaces such as homes and offices, and are recognized as essential home appliances on the road.

These humidifiers can be easily contaminated with water or moisture related. Therefore, it can be said that it is important to keep and manage the humidifier cleanly in order to prevent problems caused by contamination of the used humidifier. Specifically, since it is easy to be contaminated with bacteria, if it is used while preventing it for more than a day, the contaminated bacteria may pass through the respiratory tract and cause disease in people with weak immunity. For this reason, when using a humidifier, it is necessary to periodically change the water at least once a day and clean it with boiled and cooled water to prevent scale formation. By the way, although this humidifier cleaning task may seem like a simple task that can be done in a short time, the user considers it very cumbersome and cumbersome.

In other words, since water is always stagnant in the interior space of the humidifier, bacteria present in the water are easy to propagate. Also, it is common that conventional humidifier cleaners are made by using agricultural or horticultural or pharmaceutical disinfectants to inhibit the growth of microorganisms.

And since the ultrasonic humidifier, which is generally used the most, forms and discharges atomized humidifying particles by the ultrasonic vibrator, the water and atomized particles in contact with the vibrator are propagated by contact with contaminated air, and these bacteria are sprayed together. As the result of scattering in the air is caused, it has a problem that can rather seriously harm the health of the elderly or children.

Therefore, there is a growing awareness that it is necessary to suppress the contamination of water stagnant inside the water tank or the propagation of bacteria in the spray tank in contact with the vibrator.

However, there is a potential risk of harm to the human body when chlorine-based chemicals, agricultural, horticultural, or pharmaceutical disinfectants are dissolved in humidifier water and used indoors for a long time, and there is a potential risk of harm to the human body. It may adversely affect the human body when used indoors for a long time by weakened patients, pregnant women, or children, or when inhaled. In addition, as various problems caused by humidifier disinfectants have recently emerged, consumers' awareness of this has increased considerably.

Accordingly, there is a need to provide a method capable of suppressing contamination and bacterial growth of the humidifier even if the humidifier is periodically cleaned. Accordingly, the present inventors have studied a method for reducing contamination of stagnant water without affecting the human body. Accordingly, a bubble-generating antibacterial humidifier has been completed that can reduce the number of periodic cleanings by delaying the rate at which the water inside the humidifier is contaminated from microorganisms.

Prior art 1 (KR 10-1268866 B1) relates to a heating-type humidifier using a porous ceramic carrier, which is a water storage tank for storing water, a first space in which a porous ceramic carrier is located in the center, and an interior space separated from the first space a main body having a second space in which electrical components are embedded; a porous ceramic carrier positioned at the center of the first space; It is proposed to include a heater mounted on the inside of the ceramic carrier. However, it is not possible to more effectively suppress the contamination of the water in the water tank, and has a difference from the problem solving principle of the invention recognized in the present invention.

Prior art 2 (KR 20-0476833 Y1) relates to a humidifier that simultaneously purifies the air. It uses a tubular moisture absorption filter to simply install it inside the humidifier, and the water stored in the moisture absorption filter is uniformly distributed throughout. With moisture that is sufficiently wetted and the outside air is sucked in by the pen, purified air through the moisture absorption filter and the moisture vaporized at the same time, it purifies the indoor air and adjusts the indoor humidity. Disclosed are the contents to accurately display water dripping.

However, the prior art 2 relates to a combination of a humidifier and an air purifier, which is different from the suppression of contamination of water stored in the water tank inside the humidifier, which the present invention recognizes as a problem, and is clearly distinguished from the problem solving principle presented in the present invention. will become

Morus alba is a deciduous broad-leaved tree or shrub belonging to the family Morus alba. The scientific name is ‘Morus alba L.’. The height reaches 10 m. The leaves are ovate or broad ovate, somewhat thick and glossy, and the lower part of the leaf is sometimes divided into 3 to 5 branches. There are saw teeth on the edge of the leaf, and the petiole is about 2-3cm long. In June, male and female flowers bloom separately on one tree or bloom on different trees. Male flowers are gathered in long dendritic inflorescences and are composed of 4 stamens and 4 perianths. The fruits ripen to black purple in June. A similar tree, wild mulberry, differs from mulberry in that the style is long, the tip of the leaf is long like a tail, and the serrated tip of the leaf edge is sharp. Mulberry leaves are called jamyeop (蠶葉) and are used to grow silkworms. It is known that mulberry trees have been cultivated in Korea since the Silla Dynasty, and there is a record that a certain number of mulberry trees were planted in each village during the reign of King Hyeonjong of Goryeo. The fruit called mulberry is eaten raw or soaked in alcohol. In Chinese, the mulberry tree is called Sang (桑). It is used as medicine. In oriental medicine, the upper extremities are used to treat neuralgia, the upper lobe is used as an antipyretic agent, the inlay is used as a tonic, a hair growth stimulant and anemia prevention, and the sangbaekpi is used as a diuretic and antihypertensive agent.

Green laver mainly grows in fresh water mixed with the beach. Green seaweed is broadly divided into two groups: brown seaweed, which is wide and long like seaweed, and long-leaved seaweed, which is long and thin like hair. Brown algae are algae belonging to the genus Brown algae, and thick, hard tray-like flat roots grow attached to the rocks. The body is dark green, and the texture is harder and wider than that of green leaves. Depending on the type, the body has holes or cracks, and the size varies from 10 to 100 cm in length. Six species are known to grow in Korea, and they contain vitamins A, B, and C, protein, iodine, and iron. Leaf algae are algae belonging to the genus algae, and like brown algae, a tray-shaped flat root appears and grows attached to a rock. The body is bright green in color and has a very soft and flat leaf shape, but the shape changes depending on the environment, so there are various shapes such as bamboo leaves, kidneys, and threads. The young plant looks like a hollow tube at the bottom, but as it grows, it becomes flat and grows to a height of 10 to 20 cm. Eight species are known to grow in Korea, and they contain sodium, potassium, and magnesium.

Tangerine peel is also called ginpi (陳皮), and the redder the color is better, so it is also called hongpi (紅皮), and unripe fruit peel is also called cheongpi. It is usually collected in October or November and dried. It contains volatile essential oil, hesperidin (flavone glycoside), citric acid, and vitamin B1. It is warm in nature, non-poisonous, and the taste is spicy and bitter. It mainly acts on non-menopause and menopause, but also acts on liver cirrhosis and stomach cramps. It has effects such as Lee Gi-geonbi and humidity control hwadam. The dermis is used for the symptoms of dyspepsia, such as stomach upset (not comfortable with full stomach), anorexia, nausea, and vomiting that appear in indigestion. When abdominal distension or abdominal pain is severe, for example, Pyungwisan is used to mix chungjang and hubok. In case of severe vomiting or hiccups, add ginseng or ginseng. It is also used for coughs with a lot of phlegm, and for the symptoms of wet phlegm that produce a lot of thick white phlegm and the chest and abdomen are not comfortable, use the dermis for Lee Ki-hwadam (to pass the qi smoothly to remove the phlegm) and Banha to reduce the phlegm (to remove moisture and prevent phlegm). enhance efficacy. When used for bronchitis or upper respiratory tract infection, it removes phlegm and expands the airway, making breathing easier.

When the antibacterial composition for a humidifier further includes any one selected from the group consisting of a mulberry extract, a green seaweed extract, a tangerine peel extract, and a mixture thereof, the antibacterial activity of the water vapor vaporized by the humidifier is higher, as well as a characteristic odor of tap water. There is no odor, and as a natural fragrance, a highly palatable fragrance can be produced.

More preferably, the antibacterial composition for a humidifier may further include a cucumber extract.

Cucumber grass (Burnet-bloodwort) is a perennial herb commonly grown in mountains and fields across the country. Worldwide, it is distributed in Europe, China, Japan, and North America. The rhizome is thick and fusiform. Stems are upright, branched, 30-150 cm high. Leaves are alternate phyllotaxis, pinnate compound leaves with 3 to 13 small leaves. Root leaves have several sheets, long petioles, and small leaves have stalks of 6 to 30 mm, usually stipules. The small leaves are long oval or oval, with a rounded tip. The front side of the leaf is dark green and shiny. Flowers are densely hung in ear inflorescences from July to September, and are dark red or rarely white. The inflorescence is upright and cylindrical. The calyx has 4 branches, and there are no petals. There are 4 stamens, and the anthers are dark brown. The fruit is an aqua, with wings along the edges.

Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein.

[One. Experimental Example: Preparation of bubble-type humidifier]

A water tank manufactured in a rectangular parallelepiped shape was manufactured using a transparent acrylic plate, and a steam discharge unit was installed in the upper part of the water tank to discharge water vapor. Then, an ultrasonic vibrator and a fan were installed inside the water tank to manufacture an ultrasonic vibrating humidifier.

Next, as in the following example, a hose to which a gas cylinder is connected was connected to the bottom of the water tank, and gas was injected once every 48 hours for 30 seconds to generate bubbles from the bottom of the tank to the upper layer. In addition, in the case of ozone, an ozone generator was directly connected to the bottom surface of the water tank to generate bubbles by ozone generated from the bottom inside the water tank.

As a comparative example, it was compared with that in which water was left in the water tank without generating bubbles.

Each of the humidifiers was operated for 2 hours a day, and was operated for 10 days while periodically filling the same amount of tap water. Thereafter, water was collected from the water tanks of each Example and Comparative Example, and COD values were measured.

The results are shown in [Table 1] below.

(Unit: Index)

Referring to [Table 3], it can be seen that, in the case of the embodiment according to the present invention, the degree of contamination of the water stagnant in the water tank is lowered.

In particular, it can be seen that the degree of contamination is lowered in the case of M2 to M4, and through this, it can be confirmed that when E1 to E4 is based on the mixing range of M2 to M4, a synergistic effect by interaction appears.

In addition, in the case of M7 and M8, it was confirmed that, as E5 to E8 were mixed in the predetermined range, additional cleaning activity was shown to lower the degree of contamination, and in particular, it was confirmed that the effect of removing the odor of tap water was excellent.

[2-3. Experimental Example: Evaluation of fragrance of antibacterial composition for humidifier]

The fragrance of the water vapor generated by E1, M1 to M9 was evaluated. In order to increase objectivity, 10 undergraduate students participated, and the value of the comparative example (Con) was set to 1, and the results of the comparative example and each example were compared with an index of 1 to 10 to evaluate. In the index, the higher the number, the higher the preference (V) for the scent of water vapor.

The results are shown in [Table 4] below.

Con E1 M1 M2 M3 M4 M5 M6 M7 M8 M9 V One One One 1.4 1.6 1.5 1.4 1.6 4.4 5.1 2.1

(Unit: Index)

Referring to [Table 4], it was confirmed that Comparative Examples, E1 and M1 did not emit odor to a degree that an observer could feel. On the other hand, in the case of water vapor except for M1, it was possible to confirm a weak scent, and in the case of M7 and M8, it was observed that a softly combined scent was emitted. In particular, the overall preference for the fragrance was generally high.

Through this, in the case of M7 and M8, it can be confirmed that not only the smell of tap water is removed, but also the palatability for the fragrance of natural products generated by the combination of each extract is quite high.

Accordingly, when it falls within the above range, it can be replenished with a humidifier antibacterial composition with high palatability along with cleaning and antibacterial effects.

[2-4. Experimental Example: Evaluation of antibacterial power of antibacterial composition for humidifier]

Antibacterial activity was evaluated for E1, M3 and M7 among the Comparative Examples and Examples. Esherichia coli ATCC 8739 was used as the culture strain for the antibacterial experiment, and the evaluation method was performed according to KS M ISO 22196:2011.

The degree of the microorganisms cultured in the medium was evaluated by comparing the degree of the antibacterial composition for a humidifier with that of Comparative Example (Con) not treated, and the corresponding antibacterial power was compared with the results of the comparative example as an index of 1 to 10. . In the index, the lower the number, the better the antibacterial power (Y).

The results are shown in [Table 5] below.

Con E1 M3 M7 Y 10 6 3 2

(Unit: Index)

Referring to [Table 5], it can be seen that in the case of E1, M3 and M7 of Examples, they have a certain antibacterial activity against the strain. In particular, it can be seen that in the case of a mixture of extracts of M3 and M7, the antibacterial activity is better than that of the single extract of E1.

Accordingly, it can be confirmed that, in the case of the antibacterial composition for a humidifier according to the present invention, it is possible to inhibit the proliferation of strains through antibacterial activity within a certain range other than the cleaning effect.
