Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ultrasonic humidifier equipped with means for sterilizing water to be humidified.

Conventional technology In recent years, as social interest in health and hygiene has increased,
There is a growing demand to prevent bacteria, fungi, and the like (hereinafter referred to as microorganisms) that propagate in the humidifying water of ultrasonic humidifiers.

Conventionally, measures against microorganisms that breed in the humidifying water of ultrasonic humidifiers include (a) increasing the frequency of cleaning of the water tank where the water of the ultrasonic humidifier is atomized and the water tank that supplies water to the water tank; .

(b) For humidification water, use water with as little microbial contamination as possible.

(c) Incorporating an ultraviolet lamp (hereinafter referred to as UV lamp) into the main body (Utility Model Application No. 138928/1983).

) Administering disinfectant to humidifying water (Utility Model Publication No. 67-8669)
There were methods such as 2).

The UV lamp (c) will be explained below with reference to FIG.

FIG. 2 shows a conventional ultrasonic humidifier, in which a water tank 2 in which water is atomized is provided inside the humidifier body 1.
An ultrasonic vibrator 3 for atomizing water is installed at the bottom of the water tank 2. The ultrasonic vibrator 3 is connected to an oscillation circuit 4 which is a vibration drive output source provided directly below the ultrasonic vibrator 3.

A removable water tank 5 for automatically supplying water to the water tank 2 is mounted on the humidifier main body 1, and a water supply valve 6 is provided below the water tank 6. Above the water tank 2 is an atomization chamber 7.
There is a fan 9 that sends air to the atomization chamber 7 through an air passage 8.
is provided and fixed to the bottom inside the main body 1. Further, above the atomization chamber 7, there is provided an outlet 1o for blowing out air containing water atomized in the atomization chamber 7, that is, humidified air. Furthermore, a UV lamp 11 is fixed in the air passage 8 so as not to get wet with humidifying water, and in order to ensure that ultraviolet rays reach the humidifying water, the surface of the aquarium 2 facing the UV lamp 11 is made of ultraviolet-transmitting glass. 2& is provided.

The operation of the ultrasonic humidifier configured as above will be explained next. First, when enough water is put into the water supply tank 6 and placed at a predetermined position on the humidifier main body 1, the water is supplied into the water tank 2 while being regulated by the water supply valve 6. After that, the ultrasonic transducer 3
When the is vibrated at a frequency of 1.7 MHz output from the oscillation circuit 4, a mist of about 5 to 50 μm is generated in the atomization chamber 7, and this is sent to the air outlet 10 by the fan 9.
and is blown into the room.

On the other hand, when the UV lamp fixed in the air passage 8 is turned on, 253.7 nm ultraviolet rays (generally called germicidal radiation) are generated, and the ultraviolet rays are transmitted through the ultraviolet transmitting glass 2a.
The humidified water in the water tank 2 and a part of the atomized air are sterilized through the water tank 2.

Problems to be Solved by the Invention The conventional method (b) of increasing the frequency of cleaning the aquarium and water supply tank is time-consuming and labor-intensive, and if convenience is taken into consideration, it may not be suitable for the user's preference. Go backwards.

Regarding the water quality problem of humidifying water in (b), it can be considered that tap water is the only water that can be prepared in a general household, and it is realistically impossible to use water with a particularly low concentration of microorganisms as humidifying water, except for hot water. It is.

For sterilization using UV lamps (c), it must be installed directly in the area to be sterilized, or it must be irradiated with ultraviolet light using ultraviolet-transparent glass.If you try to install it inside an aquarium, the cost of electrical insulation will increase. However, if UV-transparent glass is used, a large surface area is required, which also costs a lot of money9.Moreover, in an aquarium, for example, only one surface is made of UV-transparent glass and the other surface is made of ABS resin. Then, there was a problem that there was a large loss during the molding process.

The method of administering disinfectants to humidifying water (2) had problems such as concerns about safety because the disinfectant was also released into the room along with the atomized water.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an ultrasonic humidifier that can effectively and safely sterilize humidification water.

Means for solving the problem In order to solve this problem, the ultrasonic humidifier of the present invention has the following features:
A water tank in which water is atomized inside the main body, an ultrasonic vibrator for atomizing water provided at the bottom of the water tank, and an ultrasonic vibrator connected to the ultrasonic vibrator and placed directly below it. An oscillation circuit that is a drive output source, a water supply tank that is detachably placed on the top of the main body and has a water supply valve for supplying water to the ice water tank, and an atomization chamber provided at the top of the water tank. and,
A fan that sends air to the atomization chamber through an air path, an inlet for the air blown by the fan, and an outlet that releases air containing mist to the outside of the machine, and is provided in the air path. The ozone generator is configured to include an ozone generator.

Effect: With the above configuration, the air sent into the atomization chamber by the fan contains ozone generated from the ozone generator. Vibrating the water in the aquarium with an ultrasonic vibrator has the effect of suppressing the growth of microorganisms to some extent, but by injecting electricity containing ozone, it mixes with air containing mist particles, causing mist particles to form. Sterilizes microorganisms inside. Therefore, microbial contamination caused by humidified air blown into the room is eliminated. After sterilization, ozone decomposes into oxygen and is harmless.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG.

In the figure, a water tank 22 for atomizing water is provided inside a humidifier main body 21, and an ultrasonic vibrator 23 for atomizing water is installed at the bottom of the water tank 22. The ultrasonic vibrator 23 is connected to a generating circuit 24 which is a vibration drive output source provided directly below the ultrasonic vibrator 23. A water supply tank 26 is mounted on the humidifier main body 21 and is detachable and has a water supply valve 26 so that water can be automatically supplied to the water tank 22.

There is an atomization chamber 27 above the water tank 2, and a fan 29 is provided that sends air to the atomization chamber 27 through an air passage 28, and is fixed to the bottom of the main body 21. Further, above the atomization chamber 27, there are provided an air outlet 30 for blowing out air containing water atomized in the atomization chamber 27, that is, humidified air, and an inlet 32 for the fan 29 to suck air. It is being Furthermore, an ozone generator 31 is installed in the air passage 8.

In the above configuration, fill the water tank 26 with sufficient water,
When placed in a predetermined position on the humidifier main body 21, the water supply valve 26
The water is supplied into the water tank 22 while being regulated. after that,
1 and 7 outputted from the oscillation circuit 24 to the ultrasonic transducer 23
When vibrated at a frequency of MHz, a mist of about 5 to 60 μm is generated in the atomization chamber 7, and this is generated by the fan 2.
9, the air is blown into the chamber through the air outlet 3o.

When operating with regular tap water as humidifying water,
There is not much of a problem, but if you leave the water in it without using it, microorganisms will grow. It is necessary to sterilize the microorganisms that cause humidity sickness and allergies.

Ultrasonic waves alone have the effect of suppressing the growth of microorganisms to some extent, but effective sterilization is achieved by sending air containing ozone generated by the ozone generator 31 into the atomization chamber. Although ozone alone has a sterilizing ability, by using ozone in an ultrasonic sound field, the aggregated bacterial cells are not easily dispersed, and the dissolution of gas phase ozone into the liquid phase is promoted. In particular, since ozone is injected into the atomized humidifying water, it exhibits effective sterilizing ability even at low concentrations (0.1 to 1 ppm).

It also has the effect of promoting the decomposition of dissolved ozone, making it safe.

Effects of the Invention As described above, according to the present invention, by using ozone in combination with ultrasonic vibration, microorganisms can be effectively sterilized with ozone, and moreover, the decomposition of ozone dissolved in humidifying water can be prevented. It also has a promoting effect, and has a great practical effect of safely and effectively sterilizing humidified water in which microorganisms have grown in the water tank of an ultrasonic humidifier.
