Abstract
The present invention provides a new technology for reducing the risk of infection and the like caused by a humidifier by using ultraviolet rays. The humidifier includes: a water tank containing water; an atomizer for atomizing water contained in the water tank; a path (18) for directing the atomized water to the outside; an opening (20) formed at one end (18a) of the path and spraying atomized water; and an ultraviolet irradiation unit (22) for irradiating the atomized water with ultraviolet light (L). The ultraviolet irradiation section (22) is configured to irradiate ultraviolet light (L) from a direction opposite to the direction (X) in which the atomized water is directed toward the opening (20).
Description
Technical Field
The present invention relates to humidifiers.
Background
In a ward or a canteen facility such as a hospital or a nursing facility, prevention of infection with viruses is a very important problem. In recent years, many facilities use humidifiers, but a biofilm is formed after the water in the water tank in the humidifier is left, and the biofilm is reported to be a risk of becoming a hotbed for legionnaire's disease. In particular, since the ultrasonic humidifier does not involve heating, the risk of becoming a hotbed for legionnaires' disease is relatively high. In this case, bacteria and the like are ejected to the outside together with the water atomized by the ultrasonic vibrator. Therefore, in the ultrasonic humidifier, although the biofilm is removed by changing water every day, the cleaning work is burdened.
On the other hand, in an ultrasonic humidifier, a method of sterilizing water in an atomizing water tank by disposing an ultraviolet lamp in the atomizing water tank storing water to be atomized is devised (see patent document 1).

Disclosure of Invention
[ problems to be solved by the invention ]
However, the above-described humidifier can sterilize the water in the tank, but cannot achieve an effect on a biofilm caused by water droplets or the like adhering to the spray path.
The present invention has been made in view of the above problems, and an exemplary object thereof is to provide a new technique for reducing the risk of infection and the like due to a humidifier by using ultraviolet rays.
[ means for solving the problems ]
In order to solve the above problem, a humidifier according to an aspect of the present invention includes: a water tank containing water; an atomizer for atomizing water contained in the water tank; a path for directing the atomized water to the outside; an opening formed at one end of the path and spraying atomized water; and an ultraviolet irradiation unit for irradiating the atomized water with ultraviolet rays. The ultraviolet irradiation unit is configured to irradiate ultraviolet light from a direction opposite to a direction in which the atomized water is directed toward the opening.
According to this aspect, even when a biofilm is formed by water droplets or the like adhering to the pathway and bacteria, viruses, microorganisms, or the like (hereinafter referred to as "bacteria or the like") proliferate, ultraviolet rays can be irradiated while the bacteria or the like are directed toward the opening together with the atomized water.
The ultraviolet irradiation part may be disposed in the path near the opening. If the ultraviolet irradiation part is disposed at a position deep from the opening part toward the deep side of the path, the ultraviolet irradiation part irradiates ultraviolet rays toward the deep side of the path, and therefore, ultraviolet rays cannot be irradiated to bacteria and the like generated between the ultraviolet irradiation part and the opening part. Therefore, according to this aspect, the area inside the path where ultraviolet light cannot be irradiated can be reduced.
The path may be provided with a reflection portion therein so that the ultraviolet rays are reflected toward the other end portion of the path. Thus, the irradiation target is irradiated with ultraviolet rays without waste.
The surface of the reflecting portion may be made of PTFE or Al. This totally reflects the ultraviolet light, and the ultraviolet light is likely to reach the deep part of the path. In addition, when the surface of the reflecting portion is made of PTFE, a biofilm is not easily formed.
The ultraviolet irradiation unit may include an LED that irradiates ultraviolet light having a peak wavelength in the range of 250 to 300 nm. This enables efficient inactivation of bacteria and the like.
The LED may be arranged such that the light-emitting surface faces the other end of the path. This allows the atomized water directed toward the opening to be irradiated with ultraviolet light from the front, thereby enabling more efficient sterilization.
The LED may be arranged such that the light emitting surface is not visible when the path is viewed from the opening. This prevents ultraviolet rays from leaking to the outside, and improves the safety of the humidifier.
The length of the path may be in the range of 10 to 250 mm. The output of the LED is within the range of 30-200 mW. Thus, the ultraviolet rays emitted from the LED can sufficiently sterilize bacteria and the like in the pathway.
The atomizer may have an ultrasonic vibrator for atomizing water into aerosol. Thus, the humidifier provided with the atomizer which does not require heating can sufficiently sterilize bacteria and the like, and can simplify the device and reduce power consumption.
Any combination of the above-described constituent elements and a scheme of converting the expression form of the present invention between a method, an apparatus, a system, and the like are also effective as a scheme of the present invention.
[ Effect of the invention ]
According to the present invention, the risk of infection and the like due to the humidifier can be reduced.

Detailed Description
Embodiments of the present invention are described below with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and overlapping description is appropriately omitted. In addition, the size ratio of each component in each drawing does not necessarily match the size ratio of an actual humidifier. The following configurations are examples, and do not limit the scope of the present invention in any way.
Fig. 1 is a sectional view showing a schematic configuration of a humidifier according to the present embodiment. The humidifier 10 shown in fig. 1 includes: a water tank 12 containing water W; an atomizer 14 that atomizes the water W contained in the water tank 12; a cylindrical path 18 for guiding atomized water (hereinafter, referred to as "aerosol 16" as appropriate) to the outside; an opening 20 formed at one end 18a of the path 18 and ejecting the aerosol 16; a fan 21 for sending out the aerosol 16 to the opening 20; an ultraviolet irradiation unit 22 for irradiating the suspended fine particles 16 with ultraviolet rays; a control unit 24 for controlling the operation of the atomizer 14 and the ultraviolet irradiation unit 22, and a housing 26 for housing the above components. The aerosol (aerosol) refers to fine liquid or solid particles floating in a gas.
Fig. 2 is an enlarged sectional view of the region R shown in fig. 1. Fig. 3 is a perspective view schematically showing the vicinity of the opening in fig. 1. As shown in fig. 2, the ultraviolet irradiation section 22 is configured to irradiate ultraviolet rays L from a direction opposite to the direction X in which the aerosol 16 is directed toward the opening 20. The opposite direction is not limited to a direction directly opposite to the direction X in which the aerosol 16 is directed toward the opening 20, and may be a direction inclined with respect to the direction X.
Even when the humidifier 10 of the present embodiment forms a biofilm due to water droplets or the like adhering to the inside of the passage 18 and bacteria or the like proliferate, the ultraviolet light L can be irradiated while the bacteria or the like and the aerosol 16 are directed toward the opening 20.
The ultraviolet irradiation part 22 of the present embodiment is disposed inside the path 18 and near the opening 20. Here, the vicinity of the opening 20 is, for example, a range within 20mm from the opening 20 to the inside of the path 18. If the ultraviolet irradiation part 22 is disposed at a position deep from the opening 22 toward the deep side of the path 18, the ultraviolet irradiation part 22 irradiates ultraviolet rays toward the deep side of the path 18, and therefore ultraviolet rays cannot be irradiated to bacteria and the like generated between the ultraviolet irradiation part 22 and the opening 20. On the other hand, the humidifier 10 according to the present embodiment can reduce the area inside the path 18 that is not irradiated with the ultraviolet light L.
The path 18 is provided with a tubular reflection portion 28 inside thereof, which is configured to reflect the ultraviolet light L toward the other end portion 18b of the path 18, in a state of being inserted and fixed to the inner wall 18 c. Thereby, the ultraviolet rays L emitted from the ultraviolet irradiation unit 22 and the ultraviolet rays L' reflected by the reflection unit 28 are irradiated to the aerosol 16 to be irradiated without waste. Therefore, the ultraviolet irradiation unit 22 having a smaller output can be used, and the cost and power consumption of the humidifier can be reduced.
The ultraviolet irradiation part 22 of the present embodiment includes an LED22a for irradiating deep ultraviolet rays having a peak wavelength in the range of 250 to 300 nm. Accordingly, since the LED22a has a certain degree of irradiation range and directivity, bacteria and the like existing in the elongated path 18 can be inactivated efficiently. The peak wavelength of the deep ultraviolet light emitted from the LED22a is preferably in the range of 260 to 290nm, more preferably 275 to 285 nm.
The surface (reflection surface) of the reflection unit 28 of the present embodiment is made of PTFE or Al. For example, a material obtained by electropolishing the surface of pure aluminum (JIS1000 series) is preferable. The reflection unit 28 configured as described above can efficiently reflect the ultraviolet rays, and therefore, the ultraviolet rays are irradiated to the irradiation target without waste. In addition, when the surface of the reflection section 28 is made of PTFE, since water droplets are less likely to adhere, a biofilm is less likely to be formed. These materials allow deep ultraviolet rays to be totally reflected and easily reach the deep part of the path.
As shown in fig. 2, the LED22a of the present embodiment has a light-emitting surface 22b arranged to face the other end 18b of the path 18. This allows the ultraviolet light L to be irradiated from the front to the aerosol 16 directed to the opening 20, and thus allows more efficient sterilization.
The LED22a of the present embodiment is disposed so that the light-emitting surface 22b is not directly visible when the path 18 is viewed from the opening 20. This prevents the ultraviolet light L from leaking to the outside, and improves the safety of the humidifier 10.
The length of the path 18 in the present embodiment is preferably within a range of 10 to 250 mm. If the length of the path 18 is short, the time taken for the aerosol 16 to be ejected to the outside may be short, and the aerosol 16 may not be irradiated with sufficient ultraviolet light. On the other hand, if the path 18 is too long, the ultraviolet rays emitted from the LED22a are less likely to reach the other end 18b of the path 18, which may unnecessarily increase the size of the humidifier 10 or require the use of an LED having a large output and a high price. The length of the path may be, for example, the shortest distance from the water surface 12a in the tank 12 to the opening 20, or may be the length of a cylindrical portion constituting the path 18.
The output of the LED22a is preferably in the range of 30-200 mW. As described above, by appropriately selecting the length of the path 18 and the output of the LED22a, bacteria and the like in the path 18 can be sufficiently sterilized by using the inexpensive LED22a having a small output.
The atomizer 14 of the present embodiment has an ultrasonic vibrator 14a that atomizes water W into aerosol 16. The humidifier 10 provided with the atomizer 14 that does not require heating can sufficiently sterilize bacteria and the like, and can simplify the device and reduce power consumption.
Further, the humidifier 10 according to the present embodiment can achieve an effect of reducing the risk of infection or the like when provided with an atomizer in which bacteria or the like can proliferate. Further, an LED for irradiating deep ultraviolet rays may be disposed in the tank 12.
The present invention has been described above with reference to the above embodiments, but the present invention is not limited to the above embodiments, and embodiments in which the configurations of the embodiments are appropriately combined or replaced are also included in the present invention. Further, modifications such as appropriately recombining the combination and the order of processing in the embodiments, and making various design changes can be applied to the embodiments according to the knowledge of those skilled in the art, and embodiments to which such modifications are applied are also included in the scope of the present invention.
