Description

handrail cleaning device

The present invention relates to a handrail cleaning apparatus, and more particularly, to a handrail cleaning apparatus in which a cleaner module for wiping a handrail can be easily replaced.

Currently, many people use moving walks or escalators, which are public facilities, so various pathogenic diseases and infections caused by viruses are occurring. Escalators are widely used in department stores, hotels, subways, airports, etc. because they have high transport capacity (6,000 to 9,000 people/hour, about 10 times more than elevators) and can move many customers in a short time. However, in proportion to how many people use it, the handrail touched by passengers is seriously contaminated by bacteria. For reference, when comparing escalator handrails and toilets, contrary to the common belief that toilets are more polluted, the survey shows that more bacteria are detected in the frame supporting the handrails. One of the methods used to solve this problem is that the operator cleans the handrail by hand using detergent and a cloth. However, since this method is performed manually, there is a problem in that it is inevitably less efficient and can easily overlook an inconspicuous part of the operator. In addition, since this method is only at the level of removing foreign substances, sterilization effect cannot be expected at all, so it looks clean with the naked eye, but there is a problem that bacteria remain.

Therefore, there was a problem that the handrail cannot always be maintained cleanly and hygienically with only manual cleaning as described above. In the end, as the handrail is managed unsanitarily, it acts as a transmission route for bacteria, and the user is infected with harmful bacteria. Frequently, a device for automatically cleaning the handrail has been developed due to the need to improve it. However, the conventional handrail cleaning apparatus has a problem in that it is inconvenient to replace the pad for wiping the handrail, and the pad itself is contaminated due to long-term installation.

An object of the present invention is to provide a handrail cleaning apparatus that facilitates replacement of a cleaner module for wiping a handrail.

According to one aspect of the present invention, in a handrail cleaning device used for a moving walk or escalator, it is installed on a frame supporting the handrail, a first storage space is formed therein, and the handrail A housing moving through the housing, a disinfecting material supply device disposed inside the housing and supplying a disinfecting material for sterilizing the handrail, disposed inside the housing and supplied to the handrail by contacting the surface of the handrail and a cleaner module for wiping the disinfecting material, and to facilitate replacement of the cleaner module, the housing includes a detachable cover on one side, and the cleaner module is a handrail cleaning device detachable by opening the cover provides

The handrail cleaning apparatus according to the present invention has the following effects.

First, since one side of the housing is opened and closed and the cleaner module for wiping the handrail can be easily replaced, there is an advantage in that the cleaner module can be easily managed.

Second, since the cleaner module for wiping the handrail can be easily replaced, there is an advantage that the handrail can be managed more hygienically.

Third, since the cleaner module can be easily replaced, there is an advantage that a professional manpower is not required for replacing the cleaner module.
