Description

TECHNICAL FIELD The present invention relates to a humidifying device, a humidifier, and a humidifying method.

The air that fills a room where people live contains germs, viruses, and the like, and these substances may adversely affect the human body. Attempts have been made to purify the indoor air by installing a device for removing germs from the indoor air, such as an air purifier.

Some of these devices are equipped with a filter that separates germs from the indoor air, but if you continue to use this device, germs will adhere to the filter and multiply, or the multiplied germs will scatter again into the air. It is not preferable from a sanitary point of view.

As a technique for suppressing the growth of these germs, for example, there is a humidifying device described in Patent Literature 1. This humidification apparatus is characterized in that the humidification filter is provided with a metal body that allows ions to elute in the water tank, and the stationary member is provided with a friction body that rubs against the surface of the metal body. It is said that it is effective in creating a comfortable space by suppressing contamination by various bacteria.

JP 2011-257093 A

However, in the technique described in Patent Document 1, when the metal body or the friction body wears down, the surface of the metal body is less likely to be rubbed and the amount of ionization decreases, resulting in the effect of suppressing the growth of various bacteria. may disappear. Also, there is no reference to viruses floating in the air, and the effect is unknown. Therefore, the problem to be solved by the present invention is to provide a humidifying device and a humidifying method having antibacterial and antiviral properties.

The inventor of the present invention has conducted intensive research and found that among metal bodies, silver ions, which are ionized silver, have effective antibacterial and antiviral properties, and the higher the concentration of silver ions, the more excellent the effect. I figured it out. The aspects of the invention completed based on this viewpoint are shown below.

Silver ions have antibacterial properties. Since the humidifying device in this aspect blows out carbonated water containing silver ions, the antibacterial action of the silver ions has the effect of suppressing the growth of germs in the atmosphere. The inventors have found that when carbonated water containing silver ions is blown out, it has antiviral properties in addition to antibacterial properties. In addition, since silver ions are easily eluted in an acidic medium, the elution is easily promoted in the flow of acidified carbonated water without providing a separate means for promoting the elution of silver. be done. Therefore, the concentration of silver ions contained in the blown carbonated water is relatively high, and the carbonated water has excellent antibacterial and antiviral properties.

(Second aspect)
The carbonated water blown into the atmosphere is vaporized or atomized and blown,
A humidifier according to the first aspect.

(Fifth aspect)
The carbonated water has a temperature of 5 to 40° C. and a pH of 4.5 to 5.6.
A humidifying device according to the third aspect or the fourth aspect.

If the temperature of the water is low, a large amount of carbon dioxide will dissolve in the water, but the amount of elution of silver ions will decrease. Moreover, the inventors have obtained knowledge that more silver ions are eluted in an acidic solution. In the above embodiment, not only carbon dioxide but also silver is relatively soluble in water, so the concentration of silver ions in the carbonated water is relatively high, resulting in excellent antibacterial and antiviral properties.

Next, a mode for carrying out the invention will be described. Note that this embodiment is an example of the present invention. The scope of the present invention is not limited to the scope of this embodiment.

The humidifying device 1 according to the present invention includes a blowout portion 36 for blowing out carbonated water into the atmosphere, a carbonated water supply means for supplying the carbonated water to the blowout portion 36, and the carbonated water supply means provided with silver ions. Carbonated water flows to the blowout part by the carbonated water supply means, is mixed with silver ions in this flow, is granulated and blown out, and humidifies the atmosphere. characterized by being Further, the humidifier according to the present invention includes a water absorbing member 35 for absorbing carbonated water, a carbonated water supplying means for supplying carbonated water to the water absorbing member 35, and the carbonated water supplying means provided to generate silver ions. and a silver ion generating mechanism, wherein the carbonated water flows to the water absorbing member 35 by the carbonated water supply means, mixes with the silver ions in this flow, and is absorbed by the water absorbing member 35. and Further, the humidifying method according to the present invention is characterized by mixing silver ions into carbonated water, granulating the carbonated water mixed with silver ions into particles, and blowing the particles out of the blowing part to humidify the atmosphere. be. The humidifying device 1 will be described below with reference to FIG.

(Carbonated water supply means)
The humidifier 1 has a carbonated water supply means. The carbonated water supply means has a water supply means, a carbon dioxide supply means, a mixer 10, a silver ion generation mechanism 20, a flow path, an on-off valve, and a water absorption member 35 (also referred to as a humidification element). The water supply means has a channel 51 through which water W flows, and supplies the water W to the water absorbing member 35 installed downstream of the channel 51 . The channel 51 has, from the upstream side, a pump 40, a branched channel 55, an on-off valve 53a, a branched channel 56, an on-off valve 53b, and an on-off valve 53c, and the channel 55 is connected to the mixer 10. . The flow path 55 can be provided with an on-off valve 53g. The carbon dioxide supply means has an on-off valve 53 d , a channel 52 through which carbon dioxide C flows, and the downstream end of the channel 52 is connected to the mixer 10 . The mixer 10 mixes water W and carbon dioxide C to obtain carbonated water. 57 and reaches the silver ion generation mechanism 20 . The channel 57 can be provided with a channel 56 connecting the channel 57 and the channel 51 and an on-off valve 53e from the upstream side. An on-off valve 53h may be provided in the channel 56, and the liquid may flow from the channel 51 side to the channel 57 side, or may flow from the channel 57 side to the channel 51 side. good too. The carbonated water that has flowed into the silver ion generating mechanism 20 mixes with the silver ions and flows out of the silver ion generating mechanism 20 to form a flow path 58 that connects the silver ion generating mechanism 20 and the flow path 51 near the water absorbing member 35 . and the flow path 51 to be supplied to the water absorbing member 35 . In addition, the channel 58 may be provided with an on-off valve 53f. Note that the flow path is not particularly limited as long as it allows liquid or gas to flow, but piping and tubes through which liquid and gas can pass can be exemplified.

A plurality of routes for the flow of the water W can be selected according to the open/close state of each of the on-off valves 53a, 53b, . . . , 53h. For example, the water W supplied from the upstream end of the channel 51 flows from the upstream side to the channel 55, the mixer 10, the channel 57, the silver ion generation mechanism 20, the channel 58, the channel 51, and the water absorbing member 35. Flow paths can be mentioned. In addition, when carbon dioxide is not included, the supply of carbon dioxide from the carbon dioxide supply means may be stopped. Specifically, the water W supplied from the upstream end of the channel 51 is supplied from the upstream side to the channel 55, the mixer 10, the channel 57, the silver ion generation mechanism 20, the channel 58, the channel 51, the water absorbing member 35, or from the upstream side to the flow path 56, the flow path 57, the silver ion generation mechanism 20, the flow path 58, the flow path 51, and the water absorbing member 35. In this route, what is blown out from the humidifier 1 is water containing silver ions. Passing the indoor air through the humidifier 1 is selected, for example, when reducing bacteria and viruses contained in the indoor air in summer. Furthermore, the water W supplied from a route not passing through the silver ion generating mechanism 20, specifically, the upstream end of the flow channel 51, flows from the upstream side into the flow channel 55, the mixer 10, the flow channel 57, the flow channel 51, A path leading to the water absorbing member 35 can be mentioned. In this route, what is blown out from the humidifier 1 is carbonated water that does not contain silver ions. It is selected when removing harmful gaseous chemical substances in the room. By contacting carbonated water with harmful gas components present in the air that are soluble in water, some of them can be dissolved and removed. Further, if carbonated water is sprayed, the alkaline gas can be neutralized and removed.

The flow rate of the water W flowing through the carbonated water supply means may be appropriately adjusted in consideration of the size of the humidifier 1 and the room in which the humidifier 1 is installed. .

The water absorbing member 35 can be provided inside the housing 30 (also referred to as casing). In addition, the housing 30 can be provided with a blower 31 , a filter 32 , a cooling coil 33 , a heating coil 34 , and a blowout section 36 . Inside the housing 30, when the air blower 31 is activated, the air outside the housing 30 flows into the housing from an opening (not shown) provided in the wall of the housing 30, and the filter 32 removes dust and the like contained in the air. is removed, the remaining air is permeated, cooled by the cooling coil 33 or heated by the heating coil 34, reaches the water absorbing member 35, is humidified, and is blown out of the housing 30 from the blowing part 36. be.
(Blowout part)
The blowout part 36 is not particularly limited, and a known blowout part can be used as appropriate. A form in which an opening is provided for discharging particulate carbonated water vaporized or atomized within the housing 30 to the outside of the housing 30 can be exemplified.

(Water supply means)
The water supplied by the water supply means is not particularly limited, but tap water can be used, for example. This water is preferably within the desired temperature range, and if the supplied water is outside the desired temperature range, means for preheating or cooling the water to bring it to the desired temperature range (as shown) not).

(Carbon dioxide supply means)
A gas containing a high concentration of carbon dioxide C is supplied to the mixer 10 by the carbon dioxide supply means. The gas can be supplied, for example, from a gas cylinder containing carbon dioxide. The concentration of carbon dioxide contained in the gas is preferably 95% or higher, more preferably 99.9% or higher, and preferably 99.98% or higher. If the concentration of carbon dioxide contained in the gas is less than 95%, the obtained carbonated water has a relatively high pH, so the amount of dissolved silver ions is small, and the desired antibacterial effect and antiviral effect may not be achieved. There is It is preferable that the carbon dioxide supplying means be capable of adjusting the amount of carbon dioxide supplied. By adjusting the supply amount, the concentration of carbon dioxide contained in the carbonated water can be adjusted, and the pH can also be adjusted, so the dissolution amount of silver ions can be assumed. For example, if you want to increase the antibacterial effect or antiviral effect, you can increase the amount of carbon dioxide supplied.

Silver ions have antibacterial and antiviral effects, and the higher the concentration, the higher the effect. In addition, silver ions have the property of being relatively highly soluble in an acidic medium. Therefore, as a medium in which silver ions are dissolved, it is preferable to use an acid medium. Examples of acidic media include carbonated water, hydrochloric acid water, and citric acid water. In particular, carbonated water is preferable because carbon dioxide can be easily obtained, and even if it is accidentally ingested, it does not harm health and is excellent in safety.

(Mixer)
Although the mixer 10 is not particularly limited, it can be, for example, a batch type container or a continuous type container. Carbonated water can be produced, for example, as follows. The downstream end of the flow path 52 is installed at the bottom of the mixer 10, water W is injected so that the water surface is higher than the downstream end, and carbon dioxide C is discharged from the downstream end. inject. As a result, carbon dioxide is dissolved in the water W to obtain carbonated water.

(Silver ion generation mechanism)
The silver ion generation mechanism generates silver ions from silver. Silver ions can be generated by an electrolysis method in which silver ions are eluted by passing an electric current through a silver plate electrode to perform electrolysis. In addition, a method using a silver-type zeolite produced by performing an ion exchange reaction in a silver nitrate solution using the ion exchange function of zeolite, and a method in which part of the Si atoms in the water-soluble glass are replaced with silver, A method using silver-containing water-soluble glass in which silver ions elute as the glass melts, a method using fine metal powder that elutes silver ions by coating the surface of resin with fine silver powder, and a method using nylon resin. A method using pellets obtained by kneading zeolite carrying silver ions can be mentioned. In particular, the method using a silver-type zeolite produced by conducting an ion-exchange reaction in a silver nitrate solution utilizing the ion-exchange function of zeolite, and the method of kneading zeolite in which silver ions are supported on a nylon resin and pelletizing it. The method using a processed material is preferable because it does not cause excessive release of ions.

Regarding the method of controlling the silver ion concentration by the silver ion generation mechanism, there is a method of controlling the elution amount of silver ions by adjusting the current value and the amount of input to set the silver ion concentration in the carbonated water to a desired value, A method of adjusting the concentration of carbonated water by immersing silver-type zeolite in a flow of carbonated water without using electrodes to elute silver ions and adjusting the concentration of carbonated water to a desired value will be described. be able to.

Commercially available silver-type zeolite can be used as appropriate, but zeolite processed into a substantially spherical shape or a pellet shape is particularly preferable because of its excellent dissolution of silver ions. As the approximately spherical silver-type zeolite, for example, a fine powder having an average particle size of about 2.5 μm is kneaded with a binder to form approximately spherical particles having an average particle size of about 4 mm. 2.5 wt % can be mentioned. As the pellet-shaped silver-type zeolite, for example, nylon resin and fine powder are kneaded and formed into a size of about 3φ×3 mm, and the silver content is about 1.5 wt %. Since it is kneaded using a hydrophilic nylon resin, it has good wettability with water and does not easily fall off. In addition, since the pellet-shaped silver zeolite exists on the surface as a fine powder, it is rich in undulations, and has a larger specific surface area than the approximately spherical silver zeolite, which has a smooth surface. It is excellent in that ions are easily eluted.

ここで、［Ｈ⁺］は水素イオン濃度、ｃは炭酸水中の二酸化炭素のモル濃度、Ｋａ（＝４．４×１０^-7）は電離定数である。 The amount of carbon dioxide dissolved in water depends on the temperature of the water, and tends to decrease as the temperature increases. Further, according to the following formula 1 (Equation 1), the more carbon dioxide dissolved in the carbonated water, the more acidic the pH of the carbonated water.

Here, [H ⁺ ] is the hydrogen ion concentration, c is the molar concentration of carbon dioxide in the carbonated water, and Ka (=4.4×10 ⁻⁷ ) is the ionization constant.

On the other hand, the amount of silver ions dissolved in carbonated water depends on the temperature of the water, and tends to increase as the temperature increases. In addition, the amount of silver ions dissolved in carbonated water tends to increase as the pH of the carbonated water decreases.

Considering these points, the carbonated water preferably has a temperature of 5 to 40° C. and a pH of 4.5 to 5.6, and a temperature of 5 to 20° C. and a pH of 4.5 to 5.6. It is more preferable that the temperature is 8 to 5.1, and it is preferable that the temperature is 10 to 15° C. and the pH is 4.86 to 4.97. Within the above range, the dissolution amount of carbon dioxide and the dissolution amount of silver ions are relatively large, resulting in excellent antibacterial and antiviral effects. If the temperature is less than 5°C, the carbonated water is cold and difficult to handle, and if the temperature exceeds 40°C, carbon dioxide may be less dissolved. If the pH is less than 4.5, the carbonated water blown into the atmosphere will have a relatively strong acidity, which may damage the equipment in the living space, and the pH is more than 5.6. If so, the amount of dissolved silver ions may decrease.

Carbonated water mixed with silver ions generated by the silver ion generating mechanism 20 preferably has a silver ion concentration of 40 to 1000 ppb, preferably 400 to 700 ppb. If the silver ion concentration is less than 40 ppb, the antibacterial effect and antiviral effect of the carbonated water blown into the atmosphere may be weakened. Carbonated water may be harmful if the concentration of silver ions is too high, but if the upper limit of the concentration of silver ions is 1000 ppb, it is not harmful and has sufficient antibacterial and antiviral properties. Become.

(Water absorbing member)
Although the form of the water absorbing member 35 is not particularly limited, for example, it may be in the form of a film through which air can permeate. In this form, the air is efficiently humidified by installing the water absorbing member 35 so as to face the direction of the airflow generated by the operation of the blower 31, which is preferable. The air passing through the water absorbing member 35 along the airflow contains particles of the carbonated water adhered to the water absorbing member 35 vaporized, and is blown out from the blowing part 36 into the atmosphere outside the housing 30 . The material used for the water absorbing member 35 may be, for example, non-woven fabric, ceramic paper, plastic, or metal. However, since it is necessary to absorb and retain water, a fiber-based one is desirable.

The carbonated water may be mixed with the silver ions generated by the silver ion generating mechanism and then supplied to the water absorbing member 35 or the blowing part 36 immediately after being mixed, but it should be at least 1 minute, more preferably 60 minutes. , it is preferable that the water is supplied to the water absorbing member 35 or the blowing part 36 after being retained. By letting it stay there for at least 1 minute, the carbonated water is mixed, resulting in excellent antibacterial and antiviral properties.

(humidifier)
The humidifier according to the present embodiment includes a water absorbing member 35, and the water absorbing member 35 is exposed to air currents, thereby diffusing the absorbed water into the air. Further, by installing the water absorbing member 35 of the humidifier inside the housing 30, it can be used as the humidifying device 1. FIG.

<Modified example of embodiment>
Although the vaporization type humidifier of the present invention has been described above, it can also be applied to a spray type humidifier. Therefore, the spray type humidifier will be described below. A spray type humidifier can be the same as an evaporative humidifier except for the following points, so the different points will be described.

The difference is that the vaporization type humidifier is provided with the water absorption member 35, but the spray type humidification device is not provided with the water absorption member 35, and a spray nozzle that sprays carbonated water and turns it into particles, especially atomization. 61 and an eliminator 62 (water removal plate) that prevents droplets of the sprayed carbonated water from scattering.

A spray nozzle 61 and eliminator 62 may be provided within housing 30 . Inside the housing 30, the air outside the housing 30 flows into the housing 30 by activating the blower 31, the dust and the like contained in the air is removed by the filter 32, and the remaining air is permeated, thereby cooling. The air cooled by the coil 33 or heated by the heating coil 34 reaches the spray nozzle 61 and is humidified, and the water droplets are removed by the eliminator 62, and the remaining atomized air containing carbonated water is discharged to the blowout part. The air is blown out of the housing 30 from 36 .
