Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hand drying and sterilizing device that blows out warm air to dry hands and fingers.

(Prior Art) A conventional hand drying device that uses hot air is a device that dries the hands and fingers with the high-speed airflow blown out by extending the hand to a position where hot air is blown out. This hand dryer does not require wiping your hands with a towel, so it has the advantage of being easy to handle as there is no need to change towels or preparing thin towels, and drying without having to come into direct contact with towels, etc. It has the characteristic of being hygienic because it can be done.

(Problem to be Solved by the Invention) However, when looking at the above-mentioned hand drying device from a hygienic point of view, although it has the advantage of being able to dry towels etc. without direct contact with hot air, it is difficult to use hot air hygienically. It is difficult to say that it is sufficiently hygienic unless it is properly managed.

Incidentally, the present applicant has previously studied various functions possessed by ozone gas and has researched the uses of ozone gas, and has found that the sterilizing function of ozone gas can be effectively applied to the above-mentioned hand drying device. Ozone gas has extremely strong oxidizing power, and it is conventionally known that this oxidizing action has strong sterilizing, decolorizing, and deodorizing effects. Utilizing its sterilizing, decolorizing, and deodorizing effects, it has been used in the past, for example, to sterilize and store food, sterilize water supplies, deodorize tap water, sterilize wounds, and deodorize indoor air.

The present invention has been made to effectively utilize the sterilizing effect of ozone gas in a hand dryer, and an object of the present invention is to provide a hand dryer that can be used more hygienically than conventional hand dryers.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration.

That is, there is a main body casing in which a space into which a hand can be inserted is formed, an electric heater and an ozone generator provided in a path for introducing air into the main body casing, and an ozone generator that is heated by the electric heater and connected to the ozone generator. The invention is characterized by comprising a blowing section for blowing warm ozone gas mixed with ozone to the main body casing, and the ozone gas in the warm ozone air is exhausted to the outside through the exhaust section of the main body casing. It is characterized by being equipped with a heating section that decomposes the.

(Function) The air sent out by the blowing section is heated by an electric heater installed in the blowing path to become warm air, and the ozone gas generated by the ozone generator is mixed in to form warm air. The ozone air is sent to the main casing and released to dry hands and fingers.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a front view showing an embodiment of the hand drying sterilizer according to the present invention, and FIG. 2 is a side view.

In the figure, 10 is a main body casing formed into a hollow box shape that forms a manual insertion space. The bottom surface of the main casing 10 is filled with hot air.
A duct 12 for introducing into the main body casing 1 is connected, and the duct 12 and the main body casing 10 are connected to each other.
0 through an inlet 14 that opens on the lower surface of the 0. A casing 20 containing a control section 16 and a Shirotsuko fan 18 serving as an air blowing section is connected to the lower part of the duct 12.

The air blowing side of the Sirotskov fan 18 communicates with the duct 12 and passes through the duct 12 to the main body casing 10.
An ozone generator 22 and an electric heater 24 are installed inside the duct 12, which is the air flow path through which air is blown out. As the ozone generator 22, a generator using electric discharge or a generator using ultraviolet rays can be used. The sterilization and deodorizing effects of ozone are more effective as the ozone concentration increases, but if the ozone concentration exceeds a certain level, it becomes harmful, so the control section 16 controls the ozone generation by the ozone generator 22.

The electric heater 24 is for heating air to make hot air, and the temperature of the hot air is also controlled by the control unit 16. In the embodiment, the electric heater 24 is provided in the upper part of the duct 12, and the ozone generator 22 is provided in the lower part of the duct 12, but the installation positions of these two devices are not particularly limited.

Further, on the front surface of the main body casing 10, there are two hand insertion holes 30, which are openings for inserting a hand.
In addition, an opening/closing lid 32 that covers the hand insertion port 30 is provided inside the hand insertion port 30. The opening/closing lid 32 is rotatably attached to the main body casing 10 at its lower part.
Attach to the ceiling with a hinge, hand insertion slot 3
The opening/closing lid 32 is provided so as to rotate when the hand is inserted from zero.

An opening for discharging the air introduced into the main body casing 10 is provided at the front of the lower surface of the main body casing 10, and a guide tube 34 for discharging the air downward and an electric heater 36 serving as a heating section are provided. The electric heater 36 is for decomposing ozone in the ozone air being exhausted.

The hand drying sterilizer of the embodiment with the above configuration is as follows:
When a hand is inserted into the main body casing 10 through the hand insertion port 30, a high-speed airflow generated by the Shirotsuko fan 18 is sent into the main body casing 10 from the duct 12 to dry the hands and fingers, but when passing through the duct 12, it is applied to the electric heater 24. Therefore, the air is heated and turned into warm air, and since ozone gas is generated in the ozone generator 22, the hands and fingers are dried by the high-speed airflow of the warm ozone air.

The concentration of ozone generated by the ozone generator 22 is appropriately controlled by the control unit 16, and the concentration of ozone air in the warm air that is applied to the hands and fingers is set to an appropriate value. Since ozone has the property of being easily decomposed by heat, the heating temperature by the electric heater 24 also needs to be appropriately controlled.

The warm ozone gas introduced into the main body casing 10 is exhausted to the outside from the guide tube 34.
At this time, the electric heater 36 heats the ozone air to render it harmless and release it. Ozone gas becomes harmful when the concentration exceeds a certain level, so electric heaters 36
It is necessary to decompose it, make it harmless, and release it.

In this manner, according to the hand drying sterilizer of this embodiment, since drying is performed using a high-speed airflow of warm ozone air, the sterilization effect of ozone is enhanced in addition to drying by warm air.
The deodorizing effect makes it possible to dry hands more hygienically. In the case of this embodiment, the main body casing 10 is formed into a substantially sealed box shape, and a safety device is provided to make ozone harmless and exhaust it at the exhaust section, so that the ozone concentration inside the main body can be considerably increased. , sterilization and deodorization functions can be enhanced. As a result, it can be suitably used not only for general drying of hands and fingers, but also in fields with particularly strict hygiene requirements, such as food-related fields, hospitals, and the like.

In addition, in FIG. 1, an operation switch 38, a timer 40, etc. are provided on the upper part of the main body casing 10. Various functions can be provided, such as controlling the ventilation time by the Sirotsukofan 18 using a timer, and setting the time to start ventilation of the Sirotsukofan 18 using a sensor that detects when a hand is inserted from the hand insertion port 30. can.

In the embodiment described above, the opening/closing lid 32 is provided inside the hand insertion port 30, but the ozone concentration in the warm ozone air may be lowered to a certain extent, or the ozone generator may be activated only when the hand is inserted. It is also possible to eliminate the need for the opening/closing lid 32 by preventing ozone air from leaking to the outside by generating ozone. In addition, if the concentration of ozone air is such that ozone gas may leak to the outside, the main body casing 10 may be formed into an open type rather than a closed box shape so that the warm ozone air is directly discharged. is also possible.

The present invention has been variously explained above with reference to preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

(Effects of the Invention) According to the hand drying sterilizer according to the present invention, as described above, since the hands and fingers are dried by the airflow of warm air and ozone air, the hands and fingers are dried by the warm air and at the same time, sterilization and deodorization by the ozone air are carried out. This makes it possible to dry hands much more hygienically than the conventional method of drying hands using only hot air. As a result, it is effective not only when used for general hand drying, but also when used by workers who handle food, such as effective sterilization and deodorization, and even more effective use.
