Description

Emergency elevator

Technical Field

The present invention relates to an emergency elevator having a cleaning function, and more particularly, to an elevator capable of preventing smoke, harmful gas, and flames from entering an elevator car in the event of a fire in a building, enabling people on a floor on which the fire occurs and a floor above the floor to be rapidly and safely evacuated through the emergency elevator, enabling the life of cage passengers using an emergency rescue apparatus provided in a cage to be prolonged in an emergency, enabling patients, pregnant women, and old people to be safely rescued, and enabling harmful substances such as harmful gas, fine dust, bacteria, viruses, germs, and the like to be removed.

Background

When a fire breaks out in a high-rise building, it is difficult to safely evacuate people on the floor and upper floors where the fire breaks out due to harmful gases, smoke, and flames generated by the fire.

Since a fire occurring in such a high-rise building has a characteristic of instantaneous spread, it is not easy to complete evacuation within an initial effective time.

Particularly, it is easy and difficult to evacuate the elderly, pregnant women and patients who are located in the medical care facilities, which becomes a factor of injury to people in case of fire. This has actually happened much in various fire cases.

In case of fire, it is possible to evacuate faster using the elevator. However, in the case of a fire in a high-rise building, the elevator may often become a fire passage. Therefore, in most buildings, evacuees are evacuated through emergency buildings rather than using elevators.

Thus, building laws, fire laws and elevator-related laws require the installation of fire zones and emergency stairways in the case of high-rise buildings. It is also required to install a certain number of emergency elevators that can be used in case of fire.

However, in an actual fire scenario, harmful gases, smoke, and flames generated from the fire may rapidly spread to a fire prevention area or an emergency staircase, and thus the fire prevention area or the emergency staircase may not function in some cases.

In addition, since a fire spreads along the outer wall of a building, it is often impossible to evacuate using an emergency staircase or a roof.

Also, the emergency elevator according to the current standard prevents smoke, heat and flames at the time of a fire occurrence and has insufficient performance for safe operation. Thus, a compact elevator is actually used only as a passage for firefighters.

Such an emergency elevator is manufactured by enhancing its strength as compared with a general elevator, and thus can be safely operated in an emergency.

However, the conventional emergency elevator is equipped with only an emergency power supply device and a built-in battery, and is not significantly different from a general elevator. Furthermore, it is difficult to expect a complete sealing for a conventional emergency elevator.

Therefore, when power cannot be supplied from the emergency power supply device or the capacity of the battery is exhausted, the compact elevator cannot operate, and smoke or flames cannot be blocked in the event of a fire.

In addition, in a conventional emergency elevator, the following cannot be dealt with immediately: a case where the cage stops between the entrances between two floors; or a situation where people in the cage are waiting for external rescue due to an urgent emergency.

In view of this, an emergency exit of approximately 400mm x 500mm in size may be provided on the upper part of the cage.

However, it is not practically feasible for children, patients, disabled persons, elderly persons, pregnant women or injured persons to escape through a small emergency exit provided in the ceiling of the cage. It is also difficult for rescuers to rescue through emergency exits.

Meanwhile, as a result of investigation of the prior art relating to the present invention, a large number of patent documents have been searched. Some of these documents are described below.

Detailed Description

A preferred embodiment of an emergency elevator according to the present invention will now be described in detail with reference to the accompanying drawings.

[ first embodiment ]

Fig. 1 to 2 show an emergency elevator according to a first embodiment of the present invention.

As shown in fig. 1 and 2, an emergency elevator according to a first embodiment of the present invention includes: an oxygen supply device 10, the oxygen supply device 10 being configured to supply oxygen to a patient in the elevator car 100; an emergency ventilation device 20, the emergency ventilation device 20 being configured to supply purified air into the elevator car 100 and to discharge contaminated air; and an emergency escape apparatus 30, the emergency escape apparatus 30 being used for emergency escape when the elevator car 100 is stopped.

The oxygen supply apparatus 10 includes: an oxygen generation unit 11, the oxygen generation unit 11 being arranged at an upper part of the elevator car 100; an oxygen storage container 12, the oxygen storage container 12 configured to store oxygen; and a length adjustable oxygen mask unit 13, the length adjustable oxygen mask unit 13 being disposed within the elevator car 100 and connected to the oxygen storage container 12 so as to supply oxygen to the patient.

The oxygen mask unit 13 is preferably housed in a storage space that is sealed by a lid (not shown) during normal times. The cover is opened to pull out the oxygen mask unit 13 if necessary.

Thus, when a person in the elevator car 100 has difficulty breathing, oxygen is supplied to the person through the oxygen mask unit 13, thereby preventing asphyxiation from occurring due to oxygen deficiency.

The emergency ventilation device 20 includes: an air cleaning device 21, the air cleaning device 21 being installed at an upper portion of the elevator car 100; a blowing duct 23 installed to connect a blowing hole 24 penetrating a ceiling of the elevator car 100 to the air cleaning device 21 and configured to supply the cleaned air to an upper inside of the elevator car 100; an air intake duct 25 installed to connect an air intake hole 26 penetrating a lower end of a side surface of the elevator car 100 to the air cleaning device 21, and configured to suck contaminated air in the elevator car 100 and supply the contaminated air to the air cleaning device 21; and a sterilizing/disinfecting device 22 installed at one side of the air cleaning device 21 to remove and disinfect toxic substances in the air.

When smoke or toxic gas enters the elevator car 100 and thus normal breathing is difficult, the air cleaning device 21 operates to suck the smoke and toxic gas in the elevator car 100. Then, sterilization and disinfection are performed by the sterilization/disinfection device 22 to purify the air. The purified air is supplied into the elevator car 100 through the blowing holes 24. Thus, the person on the elevator car 100 can breathe normally using the purified air.

Further, when the elevator car 100 stops at the fire occurrence floor and the elevator door is opened, the intake port 26 is closed and the amount of air blown from the blowing port 24 is increased.

Thus, flames, smoke, toxic gas, etc. can be prevented from entering the interior of the elevator car 100 from the outside.

The emergency escape apparatus 30 includes: an upper door 31 openably provided at an upper portion of the elevator car 100 so that people can escape to an upper side of the elevator car 100; a lower door 32 openably provided on the bottom of the elevator car 100 so that people can escape to the lower side of the elevator car 100; a slow descending device 33, the slow descending device 33 being installed at an upper portion of the elevator car 100 so that people who escape to an upper side of the elevator car 100 can descend using the slow descending device 33; and a safety bar 34, the safety bar 34 being foldably installed at a lower portion of the elevator car 100 so that a person escaping to the lower side of the elevator car 100 can hold the safety bar 34.

As shown in fig. 2, the descent control device 33 is mounted on a horizontal member 35a connecting upper portions of a pair of car frames 35.

According to the above-described structure, when the elevator car 100 stops and does not move, people can open the upper hatch door 31 to escape to the upper side of the elevator car 100, and then they can safely move downward using the slow descending device 33.

People who cannot use the upper door 31, such as children, the elderly, or patients, can open the lower door 32 to escape to the lower side of the elevator car 100.

At this time, by unfolding the safety bar 34, a person can safely escape while holding the safety bar 34.

Although not shown in the drawings, each of the upper and

lower doors

31 and 32 may be configured to be hermetically sealed by a sealing member at normal times.

As shown in fig. 3, lighting devices 45 operated by a self-charging emergency power supply system are installed at the top and bottom of the elevator car 100 so that people escaping from the elevator car 100 can safely move.

Thus, the person who escapes by using the slow descent device 33 or the person who escapes through the lower hatch 32 can move quickly without wandering in the dark, and the rescuer can move quickly to protect the person who escapes.

In addition to the oxygen supply device 10, the emergency ventilation device 20 and the emergency escape device 30, devices for various accidents occurring in the interior of the elevator car 100 can also be provided.

That is, as shown in fig. 3, an emergency medical instrument 41 and a first aid kit 42 may be further provided in the interior of the elevator car 100.

Thus, when abnormality occurs in the heart of an injured person or patient, it is possible to cope with such a situation using the emergency medical instrument 41 and to rescue the injured person using the first aid kit 42.

The emergency medical device 41 and the first aid kit 42 are preferably arranged to be accommodated in the inner wall of the elevator car 100.

This is to maximize the inner space of the elevator car 100 and to facilitate people escaping from the elevator car 100.

As shown in fig. 3, a shower 43 is further provided on the upper side of the elevator car 100. In this case, all the electric devices and electronic devices inside the elevator car 100 are disposed in a waterproof manner so that they are not affected by the operation of the shower 43.

The sprinkler 43 can prevent the spread of the fire to the inside of the elevator car 100 and can minimize the loss that the fire may cause.

A cleaning device 44 for supplying water stored in the water tank is preferably installed in the inner wall of the elevator car 100 so as to emergency clean the eyes or affected parts of the patient exposed to flames or toxic gas.

In addition to the above-described emergency exit device, the emergency elevator further includes a filter device (not shown) provided in the air blowing duct 23 to remove harmful substances such as bacteria, fine dust, and the like to maintain a clean state.

The filter device installed in the blowing duct 23 is preferably a HEPA filter or an ULPA filter.

The HEPA filter is a high performance filter that removes fine particles from air, and is referred to as a high efficiency particulate air filter.

According to the American atomic energy Association standards, a HEPA filter may be considered if 99.97% of particles larger than 0.3 μm can be removed.

HEPA filters have been developed to remove radioactive particles from air and are typically made by compressing fiberglass. The HEPA filter has a mesh-like structure and ensures that particles cannot pass through.

ULPA (ultra low penetration air) filters are high efficiency filters capable of filtering 99.999% or more of ultra-fine particles with a size of 100 nm.

ULPA filters are superior to glass fiber filters in terms of pressure difference and filtration performance, and are used as filters for air conditioning in facilities of semiconductors, electronic devices, biotechnology, and the like.

In addition, the emergency elevator further includes an ultraviolet lamp (not shown) for irradiating ultraviolet rays to the air passing through the blowing holes 24 to kill bacteria, germs, and viruses introduced into the interior of the elevator car 100.

The filter device may further include an activated carbon filter or a nano silver filter.

The active carbon filter absorbs and removes odor substances, and the nano silver filter improves the sterilization effect.

Since ultraviolet lamps, activated carbon filters, and nano silver filters are all known in the art, detailed descriptions thereof will be omitted.

In addition, a jet injection system (not shown) is provided above the elevator doors 125 to form an air curtain in front of the elevator doors of the landing doorway with the elevator car 100 stopped.

The jet spray system can suppress the introduction of smoke and pollutants from the outside.

As shown in fig. 4 to 8, the emergency elevator further comprises a door sealing device for sealing the door of the elevator.

Hereinafter, a door sealing device according to a first embodiment of the present invention will be described in detail.

As shown in fig. 4, the door frame 110 is disposed at the upper and lateral sides of the elevator car 100. The door frame 110 includes an upper door frame 111 and a pair of side door frames 113.

As shown in fig. 5, the inner ends of the pair of platform doors 130 abut against the upper door frame 111 at the middle portion of the upper door frame 111, and are coupled to the upper door frame 111 in a staggered or concavo-convex shape.

As shown in fig. 6, an upper sealing member is formed between the upper door frame 111 and the upper door edge 131. As shown in fig. 7, a side sealing member is formed between each side door frame 113 and each side door edge 133. As shown in fig. 8, a lower sealing member is formed between the platform door 130 and the lower frame 140.

Each sealed by at least one sealing member 150. The sealing member 150 may be attached to a coupling surface of the elevator car 100.

With the above-described structure, when the platform door 130 is closed, the gap is sealed by the sealing member 150, so that flames, heat, smoke, etc. are not introduced into the platform doorway.

As shown in fig. 6, in the upper sealing part, the sealing member 150 is inserted into the lateral receiving portion 132 formed in the upper door edge 131 bent twice so that the end thereof is positioned inside the upper door frame 111. Thus, the sealing member 150 comes into close contact with the upper door frame 111. The other sealing member 150 is inserted into the lateral insertion groove 112 of the upper door frame 111 so as to be in close contact with the upper door frame 111. Thus, the sealing member 150 comes into close contact with the inner surface of the platform door 130.

In order to allow the sealing member 150 inserted into the groove 112 to come into close contact with the inner surface of the platform door 130, the upper end of the platform door 130 needs to be positioned higher than the lower end of the upper doorframe 111 by 100mm or more.

However, if the height of the platform door 130 is too high, the manufacturing cost will increase. Therefore, the upper limit of the height difference is preferably 150 mm.

According to the above structure, when the platform door 130 is closed, the upper door frame 111, the platform door 130, and the upper door edge 131 are doubly sealed by the two sealing members 150.

As a result, flames, heat, and smoke generated in the event of a fire can be prevented from entering the elevator car 100.

As shown in fig. 7, in the side sealing part, the sealing member 150 is inserted into the vertical receiving portion 134 formed protrudingly forward at the end of the side door edge 133, so that the sealing member 150 comes into close contact with the end surface of the side door frame 113. Another sealing member 150 is inserted into a vertical insertion groove 114 formed in the side door frame 113 so that the sealing member 150 makes emergency contact with the outer surface of the platform door 130.

With the above structure, when the platform door 130 is closed, the side door frame 113, the platform door 130, and the side door edge 133 are doubly sealed by the two sealing members 150.

As shown in fig. 8, in the lower sealing member, a lateral metal shielding plate 135 is installed in a lower portion of the platform door 130. An accommodation space 145 having a predetermined width is formed in the lower frame 140 so as to accommodate a sealing member 150 that is brought into close contact with a side surface of the metal shielding plate 135.

That is, the sealing members 150 attached to both sides of the metal shielding plate 135 come into close contact with the side surfaces defining the receiving space 145 of the lower frame 140, thereby forming a double seal when the platform door 130 is closed.

Accordingly, it is possible to prevent flames, heat, smoke, etc. from being introduced into the elevator car 100 through the gap between the landing door 130 and the lower frame 140.

A graphite rod or a graphite plate may be used as the sealing member 150. Preferably, a graphite rod is used as the sealing member in the upper sealing part or the side sealing part, and a graphite plate is used as the sealing member in the lower sealing part.

The sealing member attached to the contact surface of the platform door 130 is preferably formed of a heat-resistant filler.

According to the emergency elevator of the first embodiment of the present invention, it is possible to prevent flames, smoke, toxic gas, and heat from entering the elevator shaft in the event of a fire. This makes it possible to use the emergency elevator for rapid evacuation.

In addition, when there is a possibility that flames or smoke may be introduced into the hoistway from the fire occurrence floor or the complete evacuation floor, the elevator car 100 is not stopped at the fire occurrence floor or the complete evacuation floor, and the landing door 130 is not opened at the fire occurrence floor or the complete evacuation floor. This makes it possible to prevent flames, smoke, and harmful gas from entering the hoistway.

When the platform door 130 is closed, flames, smoke, and harmful gas are doubly blocked by the platform door 130, the upper sealing part located above the platform door 130, the side sealing parts located at both sides of the platform door 130, and the lower sealing part located below the platform door 130.

Thus, the safety of the hoistway is ensured, so that people can be quickly evacuated using the elevator car 100 of the emergency elevator.

Generally, a hoistway installed in a high-rise building is a fire zone. However, in the event of a fire, fire doors may be opened by a panic sufferer.

Furthermore, since a small number of fire protection devices are provided in most fire zones or emergency stairways, it is not easy for many people to evacuate quickly.

In particular, it is almost impossible to evacuate all people within one hour in a high-rise building where a fire rapidly spreads.

According to the invention, the emergency elevator can be operated even during a fire. Therefore, people on the floor where the fire breaks out and the upper floor can be quickly rescued, and therefore damage to the people is reduced.

In addition, the air inside the elevator car 100 can be maintained as clean as possible by a HEPA filter, ULPA filter, activated carbon filter, nano silver filter, or ultraviolet lamp provided in the elevator car 100.

In addition, by forming the air curtain using the jet spray system provided at the upper side of the elevator door, it is possible to prevent harmful substances or contaminants from entering the elevator car 100.

In addition, the oxygen supply device and the emergency ventilation device can prevent suffocation, thereby enabling people to breathe smoothly.

Emergency medical instruments, first aid kits and cleaning devices can also be used to provide first aid to injured personnel.

Also, the sprinkler can remove flames introduced into the elevator car, thereby preventing passengers from being burned.

Emergency escape devices such as lighting devices, slow descent devices, etc. may be used to allow passengers to escape outside the elevator car as quickly as possible in the event that the emergency elevator is no longer in operation.

[ second embodiment ]

An emergency elevator according to a second embodiment of the present invention will be described with reference to fig. 9 to 13.

The emergency elevator according to the second embodiment of the present invention further includes a fire-resistant door 170 disposed in front of the landing door 130 described in the first embodiment.

When a fire is not completely suppressed while rescuing all people, the emergency elevator must be able to safely pass through the fire occurrence floor and reach the upper floor located above the fire occurrence floor in order to rescue a large number of people in the upper floor.

However, it is substantially impossible to operate the emergency elevator when the outer door of the elevator on the floor where the fire occurs is damaged by the fire or heat and when toxic gas is introduced into the elevator car.

The second embodiment of the present invention aims to solve this problem. The landing doorway and the elevator car door are protected by a fire resistant door 170 to ensure proper operation of the emergency elevator.

Preferably, the fire-resistant door 170 is configured to automatically close upon detection of a fire by the fire detection unit 200.

Although not shown in the drawings, a fire door may be further provided in front of the platform door 130 in addition to the fire-resistant door 170.

As shown in fig. 9 to 13, the emergency elevator according to the second embodiment of the present invention further includes: a fire detection unit 200 for detecting a fire occurring at each floor; and a fire-resistant door 170 rotatably installed in the platform doorway 180 such that the platform doorway 180 is closed in response to a signal from the fire detection unit 200, the fire-resistant door 170 being provided with a heat-resistant filler 170 b.

The fire-resistant door 170 is preferably a double door rotatably installed on both side walls and configured to close the platform doorway 180 by being coupled in a zigzag fashion at the center in the event of a fire.

Preferably, the fire-resistant door 170 is hingedly formed and normally received inside the wall decoration line 190a, and the surface of the fire-resistant door 170 is identical to the wall decoration line 190 a.

Thus, even if the fire-resistant door 170 is additionally installed, the aesthetic appearance can be prevented from being degraded.

Switches for operating the fire resistant door 170 are installed inside the landing doorway 180 and on the outer wall of the elevator. Each switch is configured to independently operate the fire resistant door 170.

As a result, when a fire breaks out, the fire-resistant door 170 is opened using a switch on the outer wall of the elevator, thereby enabling people to evacuate through the platform doorway 180. After evacuation is complete, the fire-resistant door 170 is closed to prevent flames, smoke, and toxic gases from entering the platform doorway 180.

The heat-resistant packing provided on the landing door 130 prevents harmful gas or smoke introduced into the landing doorway 180 from entering the hoistway.

A heat-resistant packing 130b or 170b capable of blocking harmful gas and smoke is further installed in the door edge 130a and the door frame 170a, thereby preventing harmful gas and smoke generated during a fire from entering the hoistway through a gap between the door edge 130a and the door frame 170 a.

That is, as shown in fig. 12, the door edges 130a and the door frames 170a provided on both side walls of the platform doorway 180 are engaged in a zigzag fashion at the left, right, and upper sides of the platform doorway. The heat-resistant packing 130b or 170b is installed at the end of the door frame 170a and the door edge 130 a.

In addition, a gap sealing member 160 is provided at a lower portion of the landing door 130, thereby preventing harmful gas or smoke from entering the hoistway through the lower portion of the landing door 130.

As shown in fig. 13, the gap sealing member 160 includes: a metal shielding plate 161, the metal shielding plate 161 being installed at a lower portion of the platform door 130 along a longitudinal direction; a lower door edge 162 installed at a lower portion of the platform door 130, and provided with an entrance portion 162a through which the metal shielding plate 161 passes and an accommodation space 162b having a predetermined size; a heat-resistant packing 163 installed in the accommodation space 162b and configured to be in contact with a lower portion of the metal shielding plate 161 at an upper end thereof; and a door guide shoe 164 installed in the metal shielding plate 161 to be in contact with the entrance portion 162a of the lower door edge 162 and configured to guide the movement of the platform door 130.

When a fire occurs in a high-rise building, the fire detection unit 200 detects the fire, and the fire-resistant door 170 is closed, thereby preventing flames, smoke, toxic gas, etc. from entering the platform doorway 180.

At this point, the person not being evacuated may press a switch on the outer side wall of the platform to open the fire resistant door 170. After evacuation to the platform doorway 180, one may close the fire resistant door 170 using a switch of the platform doorway 180.

In case of further installing the fire-resistant door 170, the fire-resistant door 170 is positioned in front of the platform door 130.

When the fire-resistant doors 170 are closed as described above, flames, smoke, and toxic gases are prevented from entering the platform doorway 180 due to the heat-resistant filler 170b installed in the fire-resistant doors 170. Thus, people evacuated to the landing doorway 180 can be safely evacuated by the elevator car 100.

The other configurations are the same as those of the emergency elevator according to the first embodiment of the present invention.

Although some preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. It will be understood that various changes and modifications may be made without departing from the scope of the invention as defined in the claims.
