Description

Hand sterilizer with self purifying function

The present invention relates to a hand sterilizer having a purifying function, and more particularly, to a hand sterilizer having a purifying function capable of maintaining a clean state at all times by suppressing the growth of bacteria on its own even if not periodically managed.

In general, the hand sterilizer is a product for preventing secondary infection by sterilizing or bactericidal microorganisms on the hands, and there is an increasing demand in various fields including public facilities due to concern about increased hygiene and spread of swine flu. Depending on the method of operation, it may be divided into mechanical (manual) and electronic (automatic), which is changing from the use of water and detergent to the use of hand sanitizer. Either way, keeping the sterilizer clean is an important issue.

This suggests that it can be permanently attached to a wall or can be fixed or transported in a wall and provides a high level of hygienic safety in sensitive areas, but it is difficult to maintain hygiene levels because it is common for bacteria to multiply in the wash room over long periods of use. It is true.

According to Korean Utility Model Publication No. 041147, "Hand Dryer with Disinfection Function", "A case (4) in which a disinfection space (SA) and a drying space (DA) are independently provided; First and second sensing means (20, 22) for detecting a hand drawn through the first and second hand openings (6, 8); Disinfectant solution means (38) installed inside the case (4); Blowing means (24) installed inside the case (4); And a controller 52 for independently operating the disinfectant spraying means 38 and the blowing means 24 by separate signals applied from the first and second sensing means 20, 22. .

It selectively uses only a part to reduce the power consumption or disinfectant solution and can be used simultaneously by two users, but it is also easy to propagate germs inside the case after long-term use, which threatens public health or avoids use. There are disadvantages.

An object of the present invention for improving the conventional problems as described above is to provide a hand sterilizer having a purifying function that can maintain the clean state at all times by inhibiting the growth of bacteria on its own even if not periodically managed.

In order to achieve the above object, the present invention is a device for disinfecting hands using a disinfectant: a main body having a tubular structure having a reflection surface on the upper surface of the inside and the inlet curtain communicating the inside and outside; A disinfecting unit having a liquid container and a UV lamp on the main body, and discharging disinfecting solution through a spray nozzle; An air conditioning unit including an antibacterial filter and a blowing fan on an air inlet of the main body; And a controller for detecting the entry and exit of the hand by the entrance curtain to operate the disinfection unit and the air conditioning unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an apparatus for disinfecting hands using disinfectants. Disinfectants are those which kill bacteria and are distinguished from detergents for washing bacteria, but are not limited to any of them.

According to the present invention, the main body 10 of the tubular structure is provided with an inlet curtain 22 communicating with the inside and the outside and a reflecting surface 12 on the upper surface thereof. The outside of the main body 10 has a curved top and bottom to minimize the adhesion of dust and foreign matter. The inside of the main body 10 is planarized so that there are no irregularities, thereby removing the germ propagation place, and the reflective surface 12 for diffusely reflecting the light of the UV lamp 38 described later is formed on the upper surface. Openings are formed on the front and rear surfaces of the main body 10, and the inlet curtains 22 and the covers 15 are installed, respectively. Such a body is preferably formed of a stainless material, but may also partially use a resin together.

At this time, the reflective surface 12 of the main body 10 is formed of a spherical body or a polyhedron, the inlet curtain 22 is formed of a plurality of cut pieces 26 having flexibility and high elasticity. The reflecting surface 12 is determined as a spherical body or a polyhedron according to the arrangement state of the UV lamp 38, which will be described later. In any case, the dead zone of light does not occur inside the main body 10. The inlet curtain 22 is a form in which a cutting piece 26 is formed by fixing a material having high flexibility and high elasticity (for example, silicon) to the frame 24 and cutting radially. Accordingly, the cut piece 26 of the inlet curtain 22 is normally faced to maintain the airtightness of the main body 10, but when the user's hand enters and exits, it must be elastically opened or quickly returned to its original state.

In addition, according to the present invention, the disinfection unit 30 is provided with a chemical liquid container 32 and the UV lamp 38 on the main body 10, and performs the function of sending out the disinfectant solution to the injection nozzle (34). The chemical liquid container 32 is advantageously installed on the upper portion of the main body 10 as a means for storing a disinfectant for disinfecting hands. A separate cover is installed on the upper surface of the chemical container 32 to facilitate replenishment of the disinfectant, and a spray nozzle 34 is installed on the bottom surface of the chemical liquid container 32 to expose the internal space of the main body 10 to a predetermined length. The UV lamps 38 are disposed to be adjacent to the injection nozzle 34 as a means for disinfecting the internal space of the main body 10, or a plurality of UV lamps 38 are disposed in a symmetrical position with respect to the injection nozzle 34.

At this time, the disinfection unit 30 is further provided with a plunger pump 36 on the injection nozzle 34 extending in the downward direction of the chemical liquid container (32). The plunger pump 36 can be mounted in a relatively small size and can disinfect the disinfectant one by one. The solenoid valve may be used instead of the plunger pump 36, but the time for the disinfectant to fall to its own weight becomes long. Of course, in addition to the plunger pump 36, a metering pump such as a gear pump or a piston pump may be used.

In addition, according to the present invention, the air conditioner 40 includes an antibacterial filter 42 and a blowing fan 44 on the air inlet 41 of the main body 10. The air conditioner 40 is for quickly evaporating the disinfectant on the hand, and when the blower fan 44 is turned on and off, the air inlet 41 is intermittently injected through the antibacterial filter 42.

At this time, the air conditioning unit 40 is installed on the bottom or rear surface of the main body 10, and further includes a heater 46 on the air flow path. 1 and 2, the air conditioner 40 is distributed on the bottom and the back, in the modification of FIG. 4, the air conditioner 40 is provided on the back. In the former case, an air inlet 41 is formed on the bottom surface of the main body 10, an antibacterial filter 42 is installed above the air inlet 41, and a blower fan 44 is installed on a flow path facing the rear surface. , Injects air to the inlet curtain (22) side through the rear surface. In the latter case, the air inlet 41 is formed on the cover 15 on the rear side, and the antibacterial filter 42 and the blowing fan 44 are provided adjacent to the front of the air inlet 41. The former is suitable for installing the main body 10 in the form of a wall because the air flows into the air inlet 41 at the bottom, and the latter flows the air into the air inlet 41 at the rear, so that the main body 10 is placed on a shelf or stand. Appropriate when installing on. In any of the above cases, it is preferable to provide a heater 46 for the winter in the body 10. The heater 46 may use a coil type, but a thermoelectric element may be used.

In addition, according to the present invention includes a controller 50 for operating the disinfection unit 30 and the air conditioning unit 40 by detecting the entry and exit of the hand with the inlet curtain (22). The controller 50 is installed in the lower portion of the main body 10 to input a signal through the infrared sensor 52 and the temperature sensor 54, and outputs the operating power to the disinfection unit 30 and the air conditioning unit 40.

At this time, the controller 50 of the present invention periodically detects the inputs of the infrared sensor 52 and the temperature sensor 54, the disinfection unit while turning off the UV lamp 38 when the hand enters the entrance curtain 22 30 and the air conditioning unit 40, the hand goes out, while turning on the UV lamp 38, the operation of the disinfection unit 30 and the air conditioning unit 40 is stopped, if the outside air temperature is below a certain value air conditioning unit The air of 40 is warmed up. As soon as a hand enters through the incision curtain 26 of the inlet curtain 22, the UV lamp 38 is turned off and the plunger pump 36 is operated only once after a predetermined time (for example, 2 to 3 seconds), thereby causing a certain amount of disinfectant. To draw. UV lamp 38 has a great sterilization effect, but is harmful to the human body, so do not use for hand sterilization. After the plunger pump 36 is operated, the blower fan 44 is operated for a set time after a predetermined time (rubbing the hand). When the hand is pulled out, the UV lamp 38 is turned on after a predetermined time (for example, 5 to 10 seconds) has elapsed. If the waiting time is long, it is preferable to turn on and off at a set cycle for power saving. A separate switch is provided on the substrate of the controller 50 to vary the set value of the operation time.

On the other hand, the controller 50 may be further provided with a switch for manually operating the disinfection unit 30 and the air conditioning unit 40. For example, even when a separate switch is pressed, the heater 46 of the air conditioning unit 40 is turned on and off.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
