Abstract

PURPOSE: A sterilization hand drier is provided to perform drying and sterilization of hands without installation of a separate hand sterilizer. CONSTITUTION: A sterilization hand drier comprises: an air cleaner(4) filtering the flowing air; an air compressor(5) compressing the filtered air with high pressure; a first air tank(18) keeping the compressed air; a second air tank(19) storing the compressed air kept in the first air tank for the successive decompression work; an ultra-violet ray lamp(21) practicing the sterilizing process in the second air tank; a third air tank(20) storing the sterilized compressed air for the decompression work more than 50%; and a negative ion or ozone generator(22).

Description

Sterilized combined hand dryer using sequential pressure sterilized compressed air

The present invention relates to a hand dryer, and more particularly, to a hand dryer having a sterilization and disinfection function as a stand type installation in an environment requiring clean or hygienic conditions such as a washroom, a toilet, a factory or a hospital.

In the conventional public toilet, a hand dryer is installed to allow the user to wash the water independently of the sink and to dry it quickly. As for a drying method, it is common to use warm air or cold air. However, the hot or cold air drying method uses a fan or turbo fan to blow the hands to dry the hands, but the time required for hand drying is usually 30 seconds for a simple fan and at least 15 seconds for a turbo fan. It costs. This time consuming has become an important cause for people to avoid the use of hand dryers due to time problems in large toilets with a large number of people. In addition, the problem that the water does not dry completely when drying the hand due to the limitation of the blowing pressure generated by using the fan is an important cause to avoid the use of the hand dryer.

In addition, in the fields requiring the cleanliness and hygiene of workers, such as medical, food, or precision industries, hand sterilization is required after working or finishing work. Ultraviolet rays, rubbing alcohol, etc. are used as hand sanitizing methods. Hand sanitizers are generally installed separately from the above-mentioned hand dryers. Therefore, there was a problem of lowering space efficiency or increasing installation cost. In addition, the problem of human hand infection in public places, which is becoming a problem recently, requires the development of a convenient hand sanitizer.

The purpose of the present invention for the above problems is to increase the blowing pressure to allow the hand drying operation in a short time and to ensure that the compressed air itself has a sterilizing power without the need for a separate hand sterilizer installation and hand sterilization It's about developing a device where work is all done in one device.

In order to solve the above-mentioned problems of the hand dryer and the hand sterilizer, the present invention uses the compressed air using the air compressor instead of the fan or the turbo fan with the limit of the blowing pressure, and thus the hand in the instantaneous time of 2 or 3 seconds. To avoid the problems caused by using high pressure compressed air for hand drying-impact noise, skin damage, etc. It was developed to perform the hand drying operation at a suitable pressure that does not cause the occurrence and damage of the skin. At the same time, several air spray nozzles were used to dry the hands evenly in a short time.

In addition, the UV sterilization lamp was installed in the secondary pressure reducing tank to sterilize bacteria contained in the air itself, and the sterilized air was mixed with anion or ozone in the third pressure reducing tank so that the air itself had sterilizing power. This allowed them to dry their hands with compressed air without the need for a disinfectant, while also sterilizing the bacteria in their hands.

The effect of the present invention is that the hand drying operation can be performed in a short time, eliminating the waiting time for hand drying in a large bathroom used by a large number of people, while at the same time using the hand dryer due to the waiting time or incomplete drying. The effect is to resolve the complaints of users who have avoided.

And it does not need to install a separate hand sanitizer can save the installation cost and space, there is an effect that can greatly reduce the problem of infection by the interpersonal contact in the public space, which is a problem recently.

For the detailed description of the present invention will be described with reference to FIGS. 1 and 2.

Fig. 1 shows the appearance of the device obtained as a result of the development of the present invention, in which the hand inlet 16 is provided in the front part of the main body 11.

2 is a diagram illustrating an internal view of the main body, and FIG. 3 is a conceptual diagram illustrating an operation concept of the apparatus. Based on the above drawings, first, air introduced into the air by removing air contaminants through the air filter 4 is compressed into high-pressure air through the air compressor 5, and the compressed air is the primary air tank. It is stored in 18. The compressed air stored in the primary air tank 18 is sent to the secondary air tank 19 for sequential decompression operation and contained in the air by using an ultraviolet lamp 21 in the secondary air tank 19. Sterilize germs, etc. The compressed air which has been sterilized in the secondary air tank 19 is sent to the tertiary air tank 20 for the decompression operation of 50% or more, where anion or ozone generator 22 is added to add sterilization power to the compressed air. To add anion or ozone to the compressed air.

The compressed air stored in the tertiary air tank 20 moves through the air pipe 9 to the air diffusion chamber 12 located above the hand inlet 16, where the final pressure of the compressed air is adjusted. In order to reduce the impact noise that may be generated due to the release of compressed air, a silencer 13 is installed to suppress the generation of noise. When the user's hand is inserted into the hand inlet 16, the detection sensor 14 detects this and releases sterile force compressed air having a suitable pressure for drying and sterilizing the hand. When the compressed air is discharged, a plurality of air nozzles 15 are provided to spread the compressed air evenly on various surfaces of the hand in a short time.

These operations are then performed automatically by the pressure sensor 10 attached to each air tank and the microprocessor control panel 1 in conjunction with the solenoid valve 17 and the sensing sensor 14 between the air tanks. When the pressure of the compressed air of the primary air tank 18 is 10 atm, the pressure in the secondary air tank 19 is 5 atm, and finally the pressure in the tertiary air tank 20 is automatically at 2 to 3 atm. It also plays the role of making it happen.

The water contained in the air after hand drying and sterilization is stored in the drain tank 7 through the collecting space 23 and the drain pipe 8, and when the drain tank 7 is filled with drain water, the drain valve 6 Developed as a system to discharge through the outside.

Claims

In order to increase the pressure of the blower used to remove water from the hand and to dry the hand in a short time, the compressed air itself has a sterilizing power while providing compressed air at an appropriate pressure through a sequential decompression process. This hand dryer combines both hand drying and sterilization without the need for a separate hand sanitizer.
