The present invention relates to an escalator handrail sterilization apparatus, and more particularly, to a sterilization apparatus for hygienic and clean maintenance of the handrail of the escalator.

In general, an escalator is an up and down vehicle represented with an elevator. These escalators are widely used in department stores, hotels, subways, airports, etc., because they have a higher transportation capacity (6,000 to 9,000 people / hr, about 10 times higher than elevators) and can move many passengers in a short time.

5 is a sectional view schematically showing a conventional escalator.

Referring to FIG. 5, a conventional escalator includes a step 1 for transporting passengers while circulating a fixed track, a hand rail 3 installed at both sides of the step 1, and serving as a handle, and the step 1. And a driving device 5 for driving the handrail 3.

When the escalator configured as described above operates the driving device 5, the step 1 and the hand rail 3 circulate at a constant speed along a constant track and carry passengers. Therefore, passengers on the escalator can safely move to their destinations by holding the handrail 3 only.

First, the surface of the handrail 3 is easily soiled by various foreign matters such as sweat secreted from the passenger's hand, which is not good in appearance.

Second, as described above, since it comes in contact with the hands of many passengers, contamination by bacteria is serious. For reference, contrary to the general idea that toilet toilets would be more contaminated when looking at handrails and toilet toilets, the results of the investigation showed that more bacteria were detected in the handrails.

Various methods have been devised to solve this problem, and one of the most used methods is a method of allowing the worker to directly clean the handrail 3 using a detergent and a cloth.

However, since this method is performed by hand, the efficiency is inevitably reduced, and the inconspicuous part of the operator is easily overlooked. In addition, since this method is only a level of work to remove foreign substances can not expect the sterilization effect at all, when viewed with the naked eye may look clean, but bacteria remain intact.

An object of the present invention is to provide an escalator handrail sterilization apparatus capable of maintaining hygienic and clean maintenance of the handrail of an escalator.

In addition, another object of the present invention is to provide an escalator handrail sterilization apparatus that can completely clean and sterilize both sides of the handrail which is not easy to clean.

Still another object of the present invention is to provide an escalator handrail sterilization apparatus which can be installed so that passengers do not have any inconvenience in using the escalator.

The escalator handrail sterilization apparatus according to the present invention for achieving the above object is a device for washing and sterilizing the handrail that is installed adjacent to the inlet or outlet of the escalator handrail, and is provided to surround the escalator handrail.

In addition, the nozzle 148 is provided in plurality so that the drug can reach the deep parts of both sides of the handrail 200, and are disposed at regular intervals along the inner wall surface of the cover 110. Preferably, a total of five nozzles 148 are disposed at regular intervals along the inner wall surface of the cover 110 as shown in FIG. 4.

The drug used in the drug injection means 140 may be used a variety of disinfection, disinfectant, alcohol, chlorhexidine (Chlorhexidine), chloroxylenol (PCMX), glutaraldehyde (glutaraldehyde), surfactant Etc. are representative. At this time, it is preferable to use the above-described disinfecting and disinfecting agents in accordance with the concentration within the range prescribed by law.

The ultraviolet irradiation means 150 is composed of a printed circuit board (PCB) 152 provided on the inner wall surface of the cover 110, and a plurality of light emitting diodes (154) mounted on the PCB 152. Among them, the PCB 152 is preferably a flexible printed circuit board (FPCB) having a predetermined elasticity to be applicable to a curved shape as in the case 110 of the present invention, and the LEDs 154 are superimposed on each other. It is preferable to arrange at narrow intervals so that the area can be irradiated. In addition, the ultraviolet irradiation means 150 including the PCB 152 and the LED 154 is preferably packaged with a waterproof material so as not to be affected by the chemical injected from the chemical injection means (140).

At this time, the ultraviolet (Ultraviolet rays) irradiated from the LED 154 is ultraviolet C (UV-C) that can sterilize the handrail 200, the wavelength is 100 ~ 280nm. In general, ultraviolet rays are light rays that are located outside the violet spectrum of visible light and have a wavelength of about 10 nm to 400 nm shorter than visible light. These ultraviolet rays are classified into ultraviolet rays A (UV-A), ultraviolet rays B (UV-B), and ultraviolet rays C (UV-C) according to the wavelength range. If the wavelength range is 315 to 400 nm, the ultraviolet rays A (UV- A), it is classified into ultraviolet-ray B (UV-B) if it is between 280-315 nm, and ultraviolet-ray C (UV-C) if it is between 100-280 nm. Among them, UVA (UV-A) is used for general exploration work or gastrointestinal discrimination, UVB (UV-B) is used for medical or cosmetic purposes, and UVC (UV-C) is used for various sterilization and disinfection equipment. do.

The drying means 160 is a means for drying the chemical applied to the surface of the handrail 200 is provided inside the outlet side of the case (110). When the hand rail 200 circulates at a low speed, the medicine may be dried only by heat generated by the ultraviolet irradiation means 150, but may be generated by the ultraviolet irradiation means 150 when circulating at high speed or continuously used for a long time. The heat alone is not enough. Therefore, the handrail 200 is provided inside the outlet side of the case 110 immediately before being exposed to the outside, and is dried by applying high temperature hot air to the handrail 200. At this time, since the drying means 160 has the same configuration as the drying means of the general form that is conventionally used, a detailed description thereof will be omitted.

The control unit 170 is provided on the inner wall of the middle of the case 110, as described above, and is electrically connected to the chemical injection means 140, ultraviolet irradiation means 150 and drying means 160 they 140 Control the operation. At this time, the operation of the chemical injection means 140, the ultraviolet irradiation means 150 and the drying means 160 is preferably controlled according to the operation of the hand rail 200 and the transfer speed. To this end, a detection sensor 230 for detecting whether the handrail 200 is operated and a feeding speed is absolutely necessary. In a typical escalator, measuring the feeding speed of the handrail 200 and the step (300 of FIG. 1) is performed. In order to include the detection sensor 230 may be used. Of course, if the above-described detection sensor 230 is not installed on the escalator can be additionally installed and used.

On the other hand, the case 110 is provided with a heat dissipation means 180 for dissipating heat generated by the ultraviolet irradiation means 150 and the drying means 160 to the outside. Such heat dissipation means 180 can prevent the malfunction of each component (140 ~ 170) and prevent the growth of bacteria by maintaining a constant internal temperature of the case 110 at all times. To this end, the case 110 is further provided with a temperature sensor 190 for measuring the internal temperature.

The operation of the heat dissipation means 180 is also controlled by the controller 170. The operation of the heat dissipation means 180 is determined by comparing the temperature measured by the temperature sensor 190 with the set temperature.

Looking at the washing and sterilization process of the handrail 200 using the escalator handrail sterilization apparatus 100 according to the present invention.

When the handrail 200 and step 300 circulate by operating the escalator, the detection sensor 230 detects this and notifies the controller 170. When the operation signal of the escalator is applied from the detection sensor 230, the control unit 170 operates the chemical injection means 140, the ultraviolet irradiation means 150, and the drying means 160 to clean the handrail 200 and Will be sterilized.

First, the foreign matter attached to the surface of the handrail 200 is removed through the brush 130 provided at the front end (inlet) of the case 110. The handrail 200 from which foreign substances have been removed is introduced into the case 110 to face the drug injection means 140, and the disinfecting alcohol, chlorhexidine, and chloroxy sprayed from the drug injection means 140. It is sterilized primarily by Lenol (PCMX), glutaraldehyde, surfactants and the like. At this time, the control unit 170 adjusts the amount of the drug to be injected in accordance with the conveying speed of the hand rail (200).

When the first sterilization operation is completed through the chemical injection means 140, the second sterilization operation is performed by the ultraviolet irradiation means 150. At this time, the LED 154 of the ultraviolet irradiation means 150 is disposed at a narrow interval to irradiate the overlapping area with each other can further improve the sterilization effect by the ultraviolet light.

When the first and second sterilization operations are completed through the chemical spraying unit 140 and the ultraviolet irradiation unit 150, the chemicals applied to the surface of the handrail 200 are dried using the drying unit 160. As described above, when the handrail 200 circulates at a low speed, the medicine may be dried only by heat generated from the ultraviolet irradiation means 150. However, when the handrail 200 circulates at a high speed or continuously used for a long time, the drying may be performed. The drying operation by means 160 is necessary.

The handrail 200 which has been cleaned, sterilized and dried through the above-described process is exposed to the outside of the case 110 to be in contact with the passenger's hand. Therefore, when using the escalator handrail sterilizer 100 of the present invention can always maintain the hygiene and clean handrail (200).

On the other hand, when the escalator handrail sterilizer 100 is operated for a long time, the temperature inside the case 110 is increased by the ultraviolet irradiation means 150 and the drying means 160. At this time, the control unit 170 measures the temperature through the temperature sensor 190 provided in the case 110, and when the measured temperature exceeds the set temperature to operate the heat radiation means 180 to release heat to the outside . Therefore, the inside of the case 110 may be always maintained at a constant temperature.

Although the configuration and cleaning of the escalator handrail sterilization apparatus according to a preferred embodiment of the present invention, the slaughtering process is shown in accordance with the above description and drawings, but this is only described for example and within the scope without departing from the spirit of the invention It will be appreciated by those skilled in the art that various changes and modifications are possible.
