Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an automobile humidifier that humidifies the interior of an automobile.

(Conventional technology) When the inside of a car is heated by a heating system in winter, the relative humidity inside the car decreases further because low-humidity air outside or inside the car is heated and introduced into the low-humidity inside of the car. become.

Therefore, recently, a humidifier such as that disclosed in Japanese Utility Model Application Publication No. 56-53122 is sometimes installed in a vehicle.

The humidifier disclosed in this publication uses an ultrasonic vibrator in the steam generator, and as shown in FIG. An ultrasonic vibrator 4 installed in the steam generator 3 generates steam, and a fan 5 sends out the steam into the car.

(Problem to be solved by the invention) When such a humidifier 6 is installed in a vehicle, the humidifier 6 is used only when the vehicle is in use, and the water in the water tank 1 when the vehicle is not used for a long period of time is discharged. - No supply and remains unused for a long period of time. If this condition continues, airborne microorganisms such as actinomycetes will breed or proliferate in the water tank 1 of the humidifier 6, and the microorganisms will cause a bad odor or abnormal odor to be generated when the humidifier 6 is used. There is.

Generally, the tap water injected into the water tank 1 of the humidifier 6 is treated raw water from a reservoir, lake, etc.
The microorganisms contained in this raw water include bacteria, fission bacteria such as actinobacteria, algae such as diatoms, and fungi such as mold. Such bacteria are removed by natural precipitation, chemical precipitation, sand filtration, or disinfection, or purified using copper sulfate, copper chloride, chlorine, or the like.

Even if the tap water has been freed from microorganisms, if it is left in the air, there is a risk that microorganisms will enter the water and multiply or multiply.
Even if you use tap water, if you leave the water for a long time and then use a humidifier, a strange odor may occur due to the growth of microorganisms in the water tank.

The present invention was devised in view of the drawbacks and problems of the prior art described above, and an object of the present invention is to provide a humidifier for an automobile that prevents the generation of unpleasant odors caused by microorganisms propagating in a water tank.

[Structure of the device] (Means for solving the problems) In order to achieve the above object, the present invention includes a humidifier body provided with an atomizing means, and a place removably installed in the humidifier body. A humidifier for an automobile having a water tank containing a fixed amount of water is characterized in that a water-soluble paint containing an antibacterial agent is applied to the inner peripheral surface of the water tank.

(Function) In this way, in this invention, if a water-soluble paint containing an antibacterial agent is applied to the inner peripheral surface of the water tank,
Each time you replenish water, the color of the water or the color of the paint on the inner circumferential surface of the water tank changes, so the remaining amount of antibacterial agent can be immediately determined, and the possibility of abnormal odor or malodor occurring due to the presence of microorganisms can be detected. We will find out beforehand.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic explanatory diagram showing an embodiment of the present invention;
FIG. 3 is a sectional view of the main part of FIG. 1.

In this automotive humidifier 10, an ultrasonic vibrator 12, which is operated by a current from a battery, is installed in a humidifier main body 11 as an atomizing means.

This ultrasonic transducer 12 is located in a water receiver 13 formed in the humidifier body 11, and is always immersed in water, so that the water level in the water receiver 13 is below a predetermined value. When the water level falls to
In order to protect the ultrasonic transducer 12, the current to the ultrasonic transducer 12 is stopped.

Steam atomized by the operation of the ultrasonic vibrator 12 is discharged into the vehicle interior from the air outlet 15 by a fan 14 built into the humidifier body 11.

A water tank 16 for storing a predetermined amount of water is removably attached to the humidifier body 11.

This water tank 16 is made of synthetic resin or urethane foam and is molded into a rectangular parallelepiped or cubic shape, and has a valve body 17 at the bottom, so that when the water level in the water receiver 13 decreases, the water automatically drains. The water is injected into the water receiving portion 13 at a constant rate.

In particular, in this embodiment, as shown in FIG. 2, an antibacterial agent that is soluble in distilled water, ion-exchanged water, ultra-pure filtered water, or tap water is mixed into the inner peripheral surface of the water tank 16. Paint 18 is applied.

This antibacterial agent is used to irreversibly destroy the ability of microorganisms to proliferate, and is also referred to as a sterilizing agent or a bactericidal agent.

These antibacterial agents include alcohols such as ethanol and isopropyl alcohol, and phenols such as halogen-substituted phenols, polyhydric phenols, and hexachlorophene.They are also harmless to the human body and toxic to the human body to suppress the growth of microorganisms in food. Examples of antibacterial agents or preservatives with low levels of oxidation include benzoic acid, sodium benzoate, salicylic acid, sorbic acid, potassium sorbate, dehydroacetic acid, sodium dehydroacetate, potassium propionate, and hypochlorous acid.

These antibacterial agents are mixed into the paint 18 and the water tank 1
If applied within the water tank 1, the paint 18 will gradually fade and become thinner over time, and the water tank 1 will gradually fade and become thinner.
You can see at a glance the decline in the antibacterial properties of No. 6, and you can clearly tell when it's time to replace the tank with a new one. By applying this paint in layers with different colorants, it becomes possible to better determine the amount of antibacterial agent remaining.

It is also conceivable to make the tank a double structure and use a tank coated with an antibacterial agent on the inside so that it can be easily replaced if the tank changes color and its antibacterial effect has decreased. In this case, if the inner tank is made of a relatively thin material and can be folded, a spare tank can be easily stored, and an effective tank can always be used.

[Effects of the invention] As described above, according to the invention, since a water-soluble paint containing an antibacterial agent is applied to the inner peripheral surface of the water tank of an automobile humidifier, the water tank can be left unused for a long period of time. However, since the water in the water tank has been sterilized in advance, there will be no growth or multiplication of microorganisms, and the presence of these microorganisms will eliminate any odor or odor that may occur when using the humidifier. It is possible to prevent bad odors, and since the color of the paint changes each time water is replenished, the effectiveness of the antibacterial agent can be detected, and the time to replace the water tank can be determined by observing. I can do it.
