Description

Humidifier combined an air cleaner

The present invention relates to an air purifier humidifier, and to an air purifier humidifier capable of simultaneously purifying and humidifying indoor air by using a filter having water and a sponge or a porous structure.

Recently, as awareness of healthy living has increased, the demand for humidifiers and air purifiers is continuously increasing. Humidifiers are primarily intended to maintain humidity in the air and to prevent drying, and are relatively inexpensive and bulky. On the other hand, air purifiers are intended to filter dust, impurities, and bacteria in the air and are relatively expensive.

Common humidifiers include ultrasonic humidifiers for spraying water molecules by applying vibration to water and ultrasonic humidifiers for heating water and spraying water vapor. These conventional humidifiers should be provided with a separate device such as an ultrasonic generator or a heating means for generating vibration, there is a disadvantage that the efficiency is not good because a lot of energy is consumed to drive each device.

In addition, a general air purifier is a filtration air purifier that purifies the air by passing the air containing contaminants through a dry filter, and a dust-collecting air purifier that purifies the air by adsorbing various pollutants contained in the air by passing an electric current to the electrode Has become a week. By the way, the above-described filtered air purifier and dust-collecting air purifier all have a common effect of removing various contaminants contained in the air, but did not have a function of a humidifier for imparting proper moisture to other air.

In order to solve the disadvantages of the conventional humidifier and air purifier, recently, a product capable of simultaneously purifying and humidifying the air has been marketed and sold in popularity. 1 shows the structure of such a conventional humidifying combined air purifier.

As shown in FIG. 1, a humidifier combined air purifier commercially available up to now includes a water tank 1 in which water for air purification and humidification is accommodated, and an upper side of the water tank 1 to provide the water tank 1. An upper cover (2) to cover, a suction fan (3) installed at the center of the upper cover (2), for suctioning external air to the lower tank (1), and a lower portion of the suction fan (3) Is submerged in the water in the tank (1) and the upper portion is disposed to be exposed to air and includes a rotating disk (4) rotated by a motor to pump the water in the tank (1) into the air. Through this configuration, the outside air sucked from the top is supplied to the water stored in the water tank 1 by the suction fan 3, mixed and discharged to the outside after the purification is performed. At the same time, the rotary disk 4 is to pump up the water stored in the water tank 1, and the humidified action is performed while the water is naturally evaporated.

Since the humidifier combined air purifier is an environmentally friendly filtration method using a natural purifying action of water, consumer preference is much higher than products using other filters. However, since such a conventional humidifying combined air purifier is a filtration method that simply mixes air with water, impurities or organic suspended solids that are poorly mixed with water are not easily purified, and therefore, the use of a separate chemical additive is added. In addition, as mentioned above, the humidification is performed by spontaneous evaporation of the water exposed to the air by rotating the rotating disk, the amount of water exposed is extremely small, if the evaporation does not occur easily depending on the nature of the ambient air has a humidification effect The disadvantage is that it can be insignificant. In addition, since the rotating disk must be rotated for humidification, not only the electricity consumption is very large, but the water in the tank needs to be changed periodically, which is cumbersome and wastes water resources.

The present invention was devised to solve the problems of the conventional combined humidification and air purifier as described above, by combining the natural purification and humidification of the water and the filtration function of the filter, the air that can be purged and humidified indoor air at the same time It is an object to provide a clean humidifier.

2 and 3, the air cleaner humidifier according to the present invention, the water tank 10, siphon 30, filter 40, the body casing 20, the blowing fan 50, the water pump ( 60, and a recovery pipe 70.

The water tank 10 is a housing in which water for air purification and humidification is stored, and is positioned above the main body casing 20 to be described later, and water is discharged downward through the discharge port 12 provided at the bottom. It is comprised so that it may flow to the filter 40 mentioned later.

Here, a plurality of outlets 12 may be locally formed on the entire bottom or the center of the water tank 10, and only one outlet 12 is adjusted to the outlet pipe 14 while the outlet pipe 14 is fitted. The valve 16 is preferably provided so that the amount of humidification can be adjusted by adjusting the amount of water supplied to the filter 40 to be described later. 2 and 3 illustrate an embodiment in which a control valve 16 is provided.

The siphon 30 is a dictionary meaning 'a tube used to transfer liquid from one vessel to another vessel using atmospheric pressure'. In the present invention, the siphon 30 is disposed under the water tank 10. To guide and transport the water supplied from the water tank 10 to the filter 40 located below, it is a member that serves as a kind of funnel.

As shown in FIG. 3, the siphon 30 has an upper and a lower opening, an upper portion is wider and a lower portion is narrower (aka, a light beam narrowing structure), and a lower side is formed at an upper opening of the filter housing 42 to be described later. Are fitted. In addition, a stepped portion is formed inside the upper opening of the siphon 30 so that the water tank 10 may be seated thereon. For stable seating of the water tank 10, it is preferable that a step corresponding to the step formed in the upper opening of the siphon 30 is also formed around the bottom of the water tank 10.

The filter 40 is discharged from the water tank 10 and passed through the siphon 30 receives the water falling downward, and purifies the air sucked from the outside by the blower fan 50 to be described later blown to the front side As a means, the filter housing 42 and the filter medium 46 are included.

The filter housing 42 is a housing for accommodating the filter medium 46 therein, the upper and lower portions of the filter housing 42 are covered with a perforated plate (or foam filter) 48 so that water can pass in a vertical direction, and as described later, A plurality of through holes 44 are formed in the front and rear surfaces so that the air blown by the blower fan 50 from the side can be supplied to the front side through the filter 40. Here, the through hole 44 may be configured in a circular shape, but in order to further improve breathability, it is preferable that the through hole 44 is formed of a plurality of straight long holes formed long in the vertical direction.

In addition, the upper side of the filter housing 42, the flange 43 is provided, it is preferable to be configured to be supported by the support bracket provided on the upper inner side of the main body casing 20 to be described later. According to such a configuration, the filter housing 42 is configured to be detachable from the main body casing 20 so that only the filter 40 can be separated and washed.

The filter medium 46 filled in the filter housing 42 is not limited to the type thereof as long as it is a medium capable of effectively purifying water falling from the upper side and air blown from the rear side, but may purify water and air at the same time. It is preferred that the filter medium 46 is a bio ball used in particular as the filter medium 46 of a wet dry filter.

The wet dry filter is a filter originally used to purify water in an aquarium, and fills a bioball, which is a biological filter material 46, in the filter housing 42, and filters impurities when water passes through the bioball layer. It is using the principle. The principle of filtration is an eco-friendly filtration principle that combines mechanical filtration using the structure of a bioball with a spongy structure like a small net, and biological filtration to decompose organic substances by bacteria in the bioball. The effectiveness of dry filters has been proven to be stable and widely used in aquariums. Commercially available types of bioballs for wet dry filters include ceramic ring types, gravel and substrates types, sponge or foam block types, and the like. Preference is given to the use of biobols in the form.

As mentioned above, the wet ball filter's bioball has been proven to be effective in purifying water, but it is not known whether it has the ability to purify the air. Thus, the present inventors performed the following experiment to find the air purification capacity of the Crydry filter, the difference in air purification ability according to the size of the bioball, and the height of a suitable bioball layer.

Experimental Example

First, in order to make a simulated wet dry filter, as shown in Fig. 4, two 1.5L bottled water bottles were cut in half and holes were sufficiently drilled to allow air to flow underneath. One bottled water bottle was filled with a ceramic ring bioball with a relatively small particle size, and the other bottled water bottle was filled with a ceramic ring bioball with a relatively large particle size. And, using a ruler (ruler) to mark the height at 5cm intervals on the surface of both bottles.

In order to determine the purification ability according to the size of the bioball, as shown in Figure 5 (a), both the bottled water was put charcoal powder. Then, put the bottle of mineral water on a white paper, and passes through the bioball in the bottle, and discharged through the hole formed in the bottom of the bottle, to determine the amount of charcoal powder on the white paper to determine the purification capacity according to the size of the bioball Confirmed. As a result of the experiment, as shown in Figure 5 (b), it can be seen that more of the charcoal powder from the bottled water bottle using the bioball with a relatively large particle size on the right side. This confirmed that the smaller the particles of the bioball, the higher the purification ability.

Then, in order to determine the air purification capability of the wet dry filter, the bioballs soaked in water were filled into two bottled bottles having different particle sizes, respectively, as shown in FIG. I put charcoal inside both bottles of water and blow it for 5 minutes with a hair dryer from the top. This experiment shows how well a wet bioball will purify the air when there is a flow of air containing impurities.

As a result of the experiment, as shown in Figure 6 (b), in the bottled water bottle filled with wet bio-ball, charcoal powder did not come out and was confirmed that it was completely absorbed and deposited on the upper bio-ball filtered. In a bottled water bottle filled with dry bioballs, even with a little wind, charcoal powder was blown in all directions and the filtration was not effective. Through these experiments, the wet-dry filter's ability to purify the air in the wet state was demonstrated. As a result of the experiment, as shown in (c) of FIG. 6, it was found that the male powder fell down about 5 cm from the bottled water containing the bioball, and the thickness of the bioball layer required for air filtration was about 10 cm. It was judged appropriate.

The bio ball of the Crydry filter functions to increase the humidification effect in addition to the water purification and air purification effects. In the case of the conventional rotary disk type air purifier, as can be seen from Figure 1, the area in which moisture evaporates while the rotating disk containing water is in contact with the air is limited to the outer upper portion of about 1/4 of the entire rotating disk It is difficult to expect much humidifying effect in a short time. On the contrary, the bioball of the wet-dry filter absorbs a large amount of water falling from the upper side, and due to its sponge body structure, it is directly in contact with the flow of air over a large area, so the humidification effect will be very excellent. In addition, since the humidification effect is a method using a flow of pure air, not humidification by heating or ultrasonic waves, it will be more environmentally friendly.

On the other hand, as the filter medium 46, basalt distributed in a large number in Jeju Island may be used. The porous volcanic basalt layer is known to have excellent ability to clean pollutants by itself, such as charcoal or activated carbon filters. Even when used as a filter medium (46), water purification and air filtration effects similar to those of the wet ball filter can be achieved. have. When basalt is used as the filter medium 46, the appearance of the air purifier humidifier according to the present invention is in the shape of a stone wall in Jeju Island. It is also desirable to make the image more appealing to consumers more effectively.

The main body casing 20 is provided in the lower portion of the water tank 10 and the siphon 30, accommodates the filter 40 therein, and contains a blower fan 50 and an underwater pump 60 to be described later. As the upper side is opened so that the filter 40 can be inserted or withdrawn, the upper inner surface is provided with a support bracket for supporting the filter 40. As the flange 43 of the upper part of the filter housing 42 is supported by the support bracket, the filter 40 is fixedly accommodated in the main body casing 20.

A discharge grill 22 is formed on the front surface of the main body casing 20, and the air blown by the blower fan 50 to be described later passes through the filter 40, and then through the front surface of the main body casing 20. It is configured to be discharged.

A blowing fan 50 is provided on the rear side of the main body casing 20. The blower fan 50 is rotated according to the driving of the motor to suck outside air and blow air toward the front side. The blower fan 50 is embedded in an opening formed at the rear side of the main body casing 20.

The main body casing 20 is formed to be longer than the length of the filter 40 is configured so that the water dropped from the upper portion can be temporarily accommodated, the lower portion of the main body casing 20 to pump the temporarily received water The submersible pump 60 is provided, and the pumped water is recovered to the water tank 10 along the recovery pipe 70 connecting the lower portion of the main body casing 20 to the water tank 10 and reused for air purification and humidification. .

On the other hand, by inserting a tubular fish such as goldfish in the lower portion of the main body casing 20, it is also possible to visually confirm that the water is cleanly purified by the filter 40, and at the same time to achieve a decorative effect for the tubular. Do.

So far, the configuration of the air cleaner humidifier according to the present invention has been described. Hereinafter, the operation relationship of the air cleaner humidifier according to the present invention having such a configuration will be described with reference to FIG. 7.

First, after filling the upper water tank 10, open the valve to flow the water stored in the upper water tank 10 through the outlet 12 to rotate the blowing fan 50 provided on the back side of the main body casing 20 Let's do it. Water discharged from the water tank (10) is concentrated in the siphon (30) is guided to the filter 40 and flows into the filter housing 42 to fall. As the water falls inside the filter housing 42 and the air is blown by the blower fan 50 from the rear side of the main body casing 20, the blown air is purified by the filter body wet with water and the filter 40 After passing from the rear side to the front side is discharged through the discharge grill 22 formed on the front of the main body casing (20). As air passes through the filter 40, impurities are purified and discharged with the moisture present on the surface of the filter medium 46 in the filter housing 42 to perform indoor humidification, together with the surface of the water and the filter medium 46 falling. The water present in the natural evaporation will double the humidification. In particular, in the case of the bioball used as the filter medium 46 in the present invention, as described above, the humidifying effect is more excellent because it contains a lot of water as a sponge body structure and the area in contact with air is wide. As such, the water that has undergone air purification and humidification is temporarily stored in the lower portion of the main body casing 20, and is recovered and recycled back to the upper water tank 10 through the recovery pipe 70 by the submersible pump 60. . According to such a circulation system, the air cleaning humidifier can be operated for a long time even with a small amount of water.

So far, the present invention has been described in detail with reference to the embodiments of the present invention, but the scope of the present invention is not limited thereto, and the scope of the present invention is substantially equivalent to the embodiments of the present invention.
