Go backwards.

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

(c) When incorporating an ultraviolet lamp, there are major problems in terms of space and cost, and deterioration of plastic materials due to ultraviolet rays must also be taken into consideration.

2) When administering a sterilizing agent (agent) to humidifying water, the sterilizing components from the sterilizing agent (agent) are also released into the room along with the atomized water, so there are concerns about safety.

There were problems such as:

The present invention solves these problems by having two or more electrodes in the atomizing water tank and an electric circuit for passing a current between the electrodes, thereby (a) saving time and effort; (b) Use water at the same level as tap water as humidifying water, (c) Does not require large space and cost, and does not cause material deterioration; The purpose is to prevent the growth of microorganisms in the humidified water of ultrasonic humidifiers without causing any safety issues. In other words, the purpose is to prevent microbial contamination of the air containing atomized water blown out from the ultrasonic humidifier, that is, the humidified air.

Means for Solving the Problem In order to solve this problem, the present invention provides an ultrasonic humidifier main body having an atomizing water tank equipped with an ultrasonic vibrator for atomizing water, A water supply tank that is detachably placed on the humidifier body and supplies water to the atomizing water tank, two or more electrodes provided in the atomizing water tank, and an electric current for passing a current between the electrodes. It is configured to have a circuit.

Effect With the above configuration, even if microorganisms breed in the humidifying water of the ultrasonic humidifier, they will be killed over a certain period of time by passing electricity between the electrodes installed in the tertiary water tank, and as a result, the mist will disappear after that. The air containing humidified water and blown into the room (ie, humidified air) is prevented from being contaminated by microorganisms.

Here, interactions between cells and electrodes are roughly divided into two types.

One of them is the interaction caused by electric fields, such as the release, destruction, and structural changes of intracellular substances.
Electrode reactions that act directly on cells, such as direct electrode reactions of cells and electrode reactions of released intracellular substances (

One Embodiment Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a longitudinal sectional view of an embodiment of the present invention.

In FIG. 1, an atomizing water tank 2 having an ultrasonic vibrator 3 for atomizing water disposed at the bottom is installed in an ultrasonic humidifier main body 1. Immediately below the ultrasonic vibrator 3, there is an oscillation circuit 4 for vibrating the ultrasonic vibrator 3, and above the atomization water tank 2, there is a tinization chamber 6, and the upper part of the ultrasonic humidifier main body 1 The humidified air outlet 6 is connected to the humidified air outlet 6 provided in the humidified air outlet 6. At the lower part of the ultrasonic humidifier main body 1, there is a suction lower that sucks indoor air, and the suction lower is connected to an air outlet 6 via an atomization chamber 5 through a ventilation passage 8. A fan 9 is provided in the middle of the ventilation path 8 and is fixed to the ultrasonic humidifier main body 1.
