Therefore, It should be understood that various equivalents and modifications may be present.

1, 2, 5, and 6, an apparatus for minimizing outside air inflow into an under-floor cabin of an urban railway cabin according to the present invention includes a passenger chair (not shown) provided in a cabin 10 of an urban railway vehicle 1 12), when the door (14) is opened for getting in and out of the passenger in the winter season, the air inside the room is discharged downward of the doorway (16) to minimize the inflow of cold air outside into the room It is possible to increase the heating efficiency, prevent contaminated outside air from entering the room 10, and improve the air quality in the room.

A heating heater 20 is mounted inside the lower portion of the passenger chair 12 in the room 10 of the current urban railway vehicle and the heating heater 20 is driven to heat the room 10 during the winter season .

2, an outside air inflow minimizing apparatus 100 having a blowing fan 112 capable of changing the flow path as shown in FIG. 1 is mounted on the inner lower portion of the passenger chair 12, The blowing fan 112 is controlled to rotate in the opposite direction when the door 14 is closed and when the door is opened.

That is, when the door 14 is closed, the blowing fan 112 is rotated in one direction so as to flow inward from the entrance 16 toward the side of the passenger's chair 12, The heat generated from the heater 20 can be efficiently transferred to the central portion of the room 10 to improve the heating efficiency and when the door 14 is opened, the blowing fan 112 is rotated in the other direction, The warm air is sent from the side of the passenger chair 12 to the lower portion of the doorway 16 to reduce the flow rate of the cold outside air flowing into the passenger compartment 10 through the lower portion of the doorway 16, The lowering of the internal temperature of the passenger compartment 14 due to the opening of the passageway 14 is minimized to minimize the thermal comfort of passengers due to the opening of the passageway 14 and at the same time the heating energy of the passenger compartment can be reduced.

 The apparatus for minimizing the outside air inflow of the underfloor cabin according to the present invention is provided in the lower portion of the inside of the passenger chair 12 installed in the passenger room 10 of the urban railway car 1, A blowing means 110 having a blowing fan 112 for discharging indoor air to an entrance 16 provided with a door 14 on the side of the chair 12; And a device controller 120 for controlling the blowing fan 112 to control the means 110 to discharge indoor air to the entrance 16.

Hereinafter, the present invention will be described in more detail.

1, the blowing means 110 includes a blowing fan 112 capable of controlling the forward rotation and the reverse rotation by the device controller 120 and a blowing fan 112 disposed on the front and rear surfaces of the blowing fan 112, And a protection net 114 for preventing the blowing fan 112 from being damaged.

At this time, the protection net 114 can prevent the blowing fan 112 from being winged as well as injuring the passenger.

The passenger chair 12 is equipped with a cover 12a having a lower front face and a plurality of air inlet holes (not shown) formed on both left and right sides thereof, and a heater 20 for heating is provided at a lower center thereof.

Accordingly, the air blowing means 110 is installed on both left and right sides of the heating heater 20 so as to discharge the air toward the entrance 16 of the city railway vehicle 1, (20) to the center of the room.

It is most preferable that the air blowing means 110 is installed at both ends of the passenger's seat 12. The heater 20 for the lower heating of the passenger's chair 12 may be installed depending on the allowance of the space and the installation condition of the vehicle heater, It can be installed anywhere near.

If the air blowing fan 112 is not operated when the heater 20 is installed too close to the heating heater 20, the air blowing fan 112 may be damaged by the radiation heat of the heater for heating 20, Or more.

The air blowing means 110 may include at least one blowing fan 112 and at least one blowing fan 112 may be inclined so that air can be efficiently discharged toward the entrance 16, Can be minimized.

In addition, it is preferable that the blowing means 110 is detachably installed under the passenger seat 12 so that the blowing means 110 can be separated and cleaned periodically.

When the dust or other contaminants in the air are introduced into the air blowing means 110 due to the driving of the blowing fan, the dust may move along the air and contaminate the air on the opposite side. An electrostatic dust collecting filter, an industrial filter, or the like may be applied so as to purify the contaminated air entering the inside of the blowing fan 112 so that the contaminated air is additionally purified while passing through the blowing fan 112.

When the door 14 is opened, the device controller 120 rotates the blowing means 110 to move the air in the center of the room 10 toward the entrance 16, And controls the blowing fan 112 so that air moves from the entrance 16 to the center of the room 10 by controlling the blowing unit 110 to rotate in the reverse direction when the door 14 is closed The rotation direction of the blowing fan 112 is switched.

When the door 14 is open, the device controller 120 receives the opening / closing detection signal through the door opening / closing sensor 130 which can detect the opening / closing state of the door 14, 112 and controls the air blowing fan 112 to rotate in the reverse direction when the door 14 is closed.

Of course, the device controller 120 may receive a signal from the on-board controller without receiving the opening / closing detection signal through the door opening / closing sensor 130. However, in the present invention, All belong to the equivalent technical category within the technical scope of the present invention.

Meanwhile, it is necessary to switch the rotational speed of the blowing fan 112 to a low speed or a high speed according to the temperature difference between the inside and the outside of the room. In the room, a room temperature sensor 140 is provided, 150 to monitor indoor and outdoor temperatures.

Accordingly, when the indoor temperature and the outdoor temperature are inputted from the room temperature sensor 140 and the outdoor temperature sensor 150 in real time, the device controller 120 calculates the room temperature difference between the indoor temperature and the outdoor temperature, The blowing fan 112 is controlled to rotate at a low speed when the temperature difference is equal to or lower than a predetermined temperature difference (for example, 10 ° C), and the blowing fan 112 is controlled to rotate at a high speed when the temperature difference exceeds a predetermined temperature difference (for example, 10 ° C).

The apparatus controller 120 basically operates the blowing fan 112 only when the heating heater 20 installed inside the lower portion of the passenger seat 12 in the room is operated by heating in the winter season However, even when the heater for heating 20 is not operated, the blowing fan 112 can be operated as needed. For example, in the summer season, when the door 14 is opened, the cool air inside the cabin 10 is blown out through the lower portion of the door 16, and the device controller 120 controls the blowing fan 112 The door 14 is opened so that the cold air exiting toward the entrance 16 is forcibly sucked through the side of the passenger chair and circulated to the inside of the passenger compartment 10 to reduce the outflow of cold air.

In this case, when the temperature sensed through the outdoor temperature sensor 150 is lower than or equal to the reference temperature, it can be determined that it is the winter season or the summer season. In the winter season and the summer season, Etc.).

The device controller 120 increases the rotational speed of the blowing fan 112 when the temperature sensed through the outdoor temperature sensor 150 provided outside the room during the winter season is lower than the set temperature when the door is opened, It can be controlled to rotate more slowly.

The apparatus controller 120 monitors the driving state of the heating heater 20 during the winter season to operate the blowing fan 112 when the heating heater 20 operates and the heating heater 20 does not operate The blowing fan 112 may be stopped. In this case, the operation signal of the heating heater 20 may include a temperature monitoring sensor on the surface of the heater, or may receive a drive control signal of the heater 20 for heating from the on-board equipment such as the on-board controller as a sensing signal.

Meanwhile, by incorporating an ultrasonic type toxic bacteria and virus removal device 121 in the device controller 120 to sterilize bacteria and viruses in the air of the room 10 of the urban railway vehicle 1, indoor air quality Can be improved.

Such an ultrasonic type toxic bacteria and virus removal device 121 may be installed under each passenger seat 12 of a passenger compartment of a passenger compartment of a passenger cabin to improve air quality in a passenger compartment efficiently, Space constraints such as location, additional power requirements for operation, and continuous maintenance requirements.

In addition, when operating the ultrasound-type toxic bacteria and virus removal device 121, only 1% or less (within 10 W) of the power (generally about 1 kW) entering the heater for heating 20 is added Not only the cost for the operation is minimized but also the circulation of the indoor air using the air blowing fan 112 eliminates the need for an additional air circulation fan.

Also, in terms of maintenance, the ultrasound-type toxic bacteria and virus removal device 121 is manufactured as a cartridge type, and once detached from the device controller 120 once a year, it can be used semi-permanently, thereby greatly reducing the burden on maintenance costs .

In addition, by applying the floating microorganism abatement device using ultrasonic waves to the air blowing means 110, the floating microorganisms remaining in the room air can be reduced.

3 to 6, the air flow and the temperature distribution inside the cabin according to the presence or absence of the installation of the under-floor inflow minimizing device of the under-floor cabin according to the present invention will be compared with each other.

3 and 4 are views showing a case where the door 14 is closed in an existing urban railway vehicle 1 in which an apparatus for minimizing outside air inflow into a lower portion of an urban railway cabin according to the present invention is not installed, Air flow and temperature distribution inside the room.

When the door 14 of the city railway vehicle 1 is closed, there is almost no air flow inside the room 10, so that the temperature of the upper part of the room 10 is high and the temperature of the lower part of the room 10 low. More specifically, the temperature difference at the height of 0.1 m, which is the height of the ankle of the passenger, and the height of 1.7 m, which is the height of the passenger's face, vary depending on the output of the heating heater 20 and the temperature of the outside air. ) Is large, the difference may be very large, such as 10 ° C or more. In this situation, when the door 14 is opened, the cold outside air enters into the room 10 through the lower portion of the doorway 16 in which the door 14 is opened as shown in FIG. 4, The temperature of the inside of the room 10 drops sharply. Such a rapid temperature change greatly reduces the thermal comfort of the passenger compartment 10 and excessively consumes the heating energy as the heating heater 20 operates more strongly to recover the lost heat, The temperature difference between the upper portion and the lower portion of the room 10 becomes larger, and the thermal comfort of the room 10 is lowered further.

On the other hand, FIGS. 5 and 6 are views showing a case where the door 14 is closed in an urban railway vehicle 1 in which an apparatus for minimizing ambient air inflow into an under-cabin type cabin according to the present invention is installed, And the temperature distribution inside the room.

The air flow is directed from the entrance 16 toward the heater 20 so that the heat of the heater 20 is uniformly transmitted to the inside of the guest room 10 and the heater 20 can be prevented from overheating. Conventionally, since the heating means 20 is not provided with the blowing means 110, the passenger's seat 12 immediately above the heater for heating 20 is overheated and the passenger may be burned, However, the application of the present apparatus can prevent overheating of the seat of the passenger compartment 12 located above the heater for heating 20, It is possible to transmit the heat generated by the heat exchanger 20 to the center of the passenger compartment 10 so that the temperature difference between the upper and lower passages of the passenger compartment 10 can be greatly reduced.

In this situation, when the door 14 is opened, the blowing fan 112 rotates reversely and the blowing direction is reversed so that the flow direction of the air also changes from the heating heater 20 to the entrance 16, It is possible to minimize the inflow of air into the passenger compartment 10 through the lower portion of the doorway 16 and warm the inflow cold air. Generally, when the cold outside air flows into the room 10 through the lower portion of the doorway 16, warm indoor air flows out to the outside of the room 10 through the upper portion of the doorway 16. In order to minimize the inflow of the cold outside air, Can be minimized, so that energy loss can be reduced.

6, the temperature inside the room 10 when the door 14 is closed and when the door 14 is opened can be maintained without a large change, thereby preventing a decrease in the thermal comfort of the room 10, The heating energy can be reduced, and the temperature difference between the upper and lower parts of the room 10 can be minimized to improve the thermal comfort.

Furthermore, the device controller 120 is further provided with a small-sized air purification device 121 using ultrasound to infect microorganisms such as viruses and bacteria inside the room 10 to improve the indoor air quality of the room 10, It is possible to minimize the propagation of passengers by the passengers.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The scope of protection of the present invention should be construed under the following claims, and all technical ideas within the scope of equivalents thereof should be construed as being included in the scope of the present invention.
