Description

Intelligent Anti-Virus Elevator

The present invention relates to an intelligent anti-virus elevator, and provides an operation control structure in which the UVC sterilization mode is activated only under unmanned conditions without human access, so that strong sterilization by UV-C can be safely and quickly performed without human exposure It is about an intelligent anti-virus elevator.

Bacteria are independent cells that can reproduce on their own and are classified as organisms. Viruses cannot reproduce on their own, and can reproduce only when cells of living organisms are used as hosts. Because viruses mutate easily, it is difficult to develop a cure or vaccine, so hygiene prevention is the most important.

Recently, a social disaster that occurs periodically and appears most widely is a viral infection. In the case of a highly contagious virus such as the coronavirus, blocking the transmission route is the primary prescription for disaster prevention. However, in the case of modern people who live in cities, they cannot help but engage in face-to-face activities. In addition, one of the most meaningless and frequent meeting places in building-based city life is the elevator space.

Elevators, which are vertical means of transportation, are classified according to the purpose of use, such as for passengers and for cargo. In the case of hospitals, they are classified into patients for space movement of patients, passengers for visitors and the general public, and transport of medicines and meals. In addition, hospital elevators are essentially installed in buildings with two or more floors to move patients to operating rooms and examinations.

As such, elevators installed in hospitals are equipped with elevators exclusively for operating rooms in large hospitals, but small and medium-sized hospitals are used in combination with general passengers such as caregivers and hospital visitors, making them vulnerable to the rapid spread of infection. In addition, elevators move infectious bacteria between floors and endanger the entire building, so a space sterilization method that meets various situations and conditions is required.

Currently, elevator disinfection is being carried out at the level of disinfection service and cleaning work by regular professional companies, but the reality is that it is not able to respond to various types of viruses. Disinfection and cleaning of frequently touched areas such as handrails and buttons for each floor in the elevator are mainly carried out, but the general disinfection of the floor and the entire wall is insufficient.

*Technologies that have improved these problems are being researched, Korean Patent Publication No. 10-2019-0061183 'Elevator with air sterilizer using ultraviolet rays and plasma', Korean Patent Publication No. 10-2009-0044661 'inside the elevator' An air freshener and sterilant injection device' and the like fall under this category. They can prevent infection with infectious diseases as a sterilization elevator that has advanced from the level of an air purifier.

The 'elevator applied with an air sterilizer using ultraviolet rays and plasma' is sterilized using UV technology and plasma, preventing the spread of infection by blocking the source of harmful substances and infectious bacteria, but sterilization is applied regardless of people entering or exiting the elevator There is a limit to not responding to the harmfulness of ultraviolet (UV) to the human body.

The 'air freshener and disinfectant injection device in the elevator' sprays disinfectant to passengers and pets to prevent and prevent infection by pests, pathogenic bacteria and viruses, so there is a limit to sterilization remaining in the elevator.

As such, the above-described technologies do not consider the harmful aspect of the sterilization means to the human body. In addition, there is a need for automatic control reflecting the operating state of the elevator and anti-virus devices to be implemented quickly and powerfully in terms of disaster safety, and to enable virus removal in a harmless way to humans.

It can be made of a configuration that

In addition to this, other types of sensors capable of detecting the entry and exit of a person may be included.

The infrared sensor 110 is an infrared human body detection sensor (PIR sensor, Passive Infrared Sensor) that is most commonly used to detect the entry and exit of people such as entrances and exits of apartment households. It can be manufactured, so it is easy to design waterproof and drip-proof.

The infrared sensor 110 is installed at a set point in the interior space 10 of the elevator, detects people, animals, etc. by heat detection, and generates boarding information A when there are passengers. If there is no passenger, boarding information (A) is not generated.

The CCTV 120 transmits photographing information to a specific receiver using a wired or special wireless transmission path. The interior space 10 of the elevator is photographed, and a person determination program is installed to generate boarding information A when there is a passenger. Similar to the infrared sensor 110, boarding information A is not generated when there is no passenger.

The weight sensor 130 is a sensor that detects the weight of a person or animal boarding the elevator. As shown in FIG. 3, the weight sensor 130 is disposed on the bottom surface of the elevator body 20, detects the weight of a person or animal boarding into the elevator inner space 10, and generates boarding information A.

Similar to the infrared sensor 110 and CCTV 120, boarding information A is not generated when there is no occupant.

The location where the weight sensor 130 is installed may be changed as needed.

At least one of the infrared sensor 110, the CCTV 120, and the weight sensor 130 may be selected and installed, but it is preferable to install all of them to redundantly monitor the occupants in the elevator to promote occupant safety.

If installed together, it can sterilize the whole by rotating 180 degrees.

The photocatalyst 500 is coated on the inner wall of the elevator to improve sterilization efficiency.

According to the sterilization module 300 as described above, the sterilization module 300 irradiates UVC rays (UVC refers to ultraviolet light with wavelengths between 200 - 280 nm) having a range of 200 to 280 nm so that the interior space 10 of the elevator to be sterilized.

As shown in FIGS. 7 and 8 , the sterilization module 300 is installed on the upper surface of the interior space 10 of the elevator and irradiates UVC rays so that there is no unsterilized area in the interior space 10 of the elevator.

UVC rays can sterilize 99% of the irradiated area within a few seconds, and has the highest sterilization power among ultraviolet rays UV-A, UV-B, and UVC.

UVC rays are as dangerous as they are highly bactericidal, so situations that expose the human body to UVC rays should be minimized.

And depending on circumstances, ultraviolet light having a wavelength in a range other than UVC light may be used for sterilization.

The photocatalyst 500 serves to increase the sterilization effect according to UV irradiation. It reacts with UVC rays and promotes photochemical reactions, increasing the sterilization effect.

The photocatalyst 500 may be coated on the wall surface of the interior space 10 of the elevator, coated on the entire area, or coated on only some special areas.

The control module 400 is a module that controls sterilization based on the operation of the intelligent anti-virus elevator 1. Boarding information (A) and operation state information (B) are received from the human detection sensing module 100 and the elevator motion detection module 200, and an activation signal or a deactivation signal is generated.

Then, the generated activation signal or inactivation signal is transmitted to the sterilization module 300 to control the operation of the sterilization module 300.

In an embodiment of the present invention, as shown in FIG. 7 , the control module 400 includes an activation signal generating unit 410, a first deactivation signal generating unit 420, and a second deactivation signal generating unit 430. .

The activation signal generating unit 410 generates an activation signal to activate the operation of the sterilization module 300 .

The activation signal is generated by detecting the time when the occupant leaves the elevator interior space 10 from the boarding information (A) and operation state information (B).

The first deactivation signal generation unit 420 generates a deactivation signal for inactivating the operation of the sterilization module 300 .

When the standard sterilization time is set and the activation signal is transmitted to the sterilization module 300, time counting starts and when the standard sterilization time is reached, an inactivation signal is generated.

When UVC rays are irradiated for a certain period of time, the irradiated area is sterilized.

Therefore, the interior space 10 of the elevator where no person is on board can satisfy the sterilization function when the sterilization module 300 is operated for a certain period of time without the need for continuous sterilization, The deactivation signal generation unit 420 is operated.

The second deactivation signal generation unit 430 generates a deactivation signal for inactivating the operation of the sterilization module 300 .
