Description

Detailed Description of the Invention [Object of the Invention] (Industrial field in Icheon) The present invention is a device that is installed on the ceiling of a railway vehicle, for example, and shakes the blowing air that is exchanged with heat and blown out from the ceiling into the interior of the vehicle. The present invention relates to a ceiling fan device for a vehicle that guides the air while moving and periodically changes the blowing direction of the blowing air.

(Prior art) For example, for railways as shown in Figure 4! Some 11 cars 1st class have an air conditioner 3 in the ceiling 2 of the car body, and such cars 1 perform air conditioning operation in summer and winter, and dehumidify operation in the rainy season 11, r. This is done to ensure that the air quality and humidity inside the vehicle 4 are always maintained in a comfortable state. Furthermore, some commuting vehicles are equipped with a swing type louver 5 near the outlet of the air conditioner 3 that has a four-swing function. It is possible to guide cold air to the vicinity of entrances and exits 6...7, where density tends to increase.

Further, the vehicle 1 as described above has doors 8...9 for getting on and off.
4 Di'. There are vehicles with 1/car or 5 doors/car, but recently, vehicles with 6 doors/car are also being considered to allow for smooth boarding and alighting of passengers during rush hours. .

(The invention is a corner! Problem to be solved) By the way, in such a vehicle 1, when the door 8... is opened during cooling in mid-summer, hot air from outside the vehicle flows from the entrance/exit door 6... 4, causing drastic temperature changes, even at entrances and exits...Passengers in the vicinity could feel heat stress and other discomfort.

Furthermore, due to such temperature changes in the room 4, the air conditioner 3's O N u: 7 interval may be increased or the air conditioner 3 may be
It was necessary to increase the operating rate of the air conditioner 3 by increasing the operating frequency of the air conditioner 3.

In the case of a model equipped with a louver 5, the louver 5 is the fourth
As shown in the figure, the door 9... is swung to the closed side and the air conditioning a! When the blown air 10 of 3 is guided to the side where the door 9 is closed, outside air 12 such as hot air heated by the concrete of the platform 11 and exhaust heat from the equipment (not shown) is drawn into the inside of the car 4. As a result, severe temperature changes could occur in the interior of the vehicle 4.

In vehicles with 5 doors/vehicles, these defects were greater than in vehicles with 4 doors/vehicles.

Here, the dashed-dotted line 10a in FIG. 4 shows the blowing air that is directed towards the door 8 opened by the louver 5, and the dashed-dotted line 10b shows the air that is guided to the central part of the vehicle interior. It shows the blowing wind.

Also, in general, commuter cars have short distances between stations, with doors 8...
Due to the frequent opening and closing of the air conditioner, the air conditioner had to be constantly operated at a high operating frequency, even in vehicles equipped with an inverter-based air conditioner. In this case, the entrances and exits 6, 7, and so on are made into passenger compartments, and the air filter 3 and louver 5 are equipped with air filters and control methods that are less susceptible to the influence of outside air. 9. had to be adopted.

The purpose of the present invention is to prevent outside air from entering the vehicle and to prevent a drastic change in the amount of fish inside the vehicle.
The purpose of the present invention is to provide a ceiling fan device for a vehicle that is highly efficient.

[Invention {1.1] (Means and actions for solving the problem) In order to achieve the goal 1, the present invention selects the door of any of the stones (It!I door). A ceiling fan device for a vehicle is provided with a louver in the top part of the vehicle body, and guides the air blown from the ceiling into the interior of the vehicle while changing the direction between the left and right sides of the vehicle body using the louver. , when the door is opened, the louver is activated, and the door 17J IJj notifies the door opening D111.
I: Based on No.j, the vehicle is temporarily stopped at the maximum swing angle when the air is guided to the side of the car body on the side where the door is open.
The purpose is to continuously blow the blown air to the side of the door DI release side and distribute it along the side of the door open side.

By doing so, the present invention prevents outside air from entering the interior of the vehicle and prevents a sudden build-up of temperature inside the vehicle.

(Example) Each example of the present invention will be described below with reference to FIGS. 1 to 3. Note that the same reference numerals are given to the parts that are the same as those described in the prior art section, and the description thereof will be omitted.

FIG. 1 schematically shows the main parts of a first embodiment of the present invention, in which 5a is a ceiling fan device installed in a railway vehicle 1, and 5 is an airfoil cross section, for example. A plurality of louvers are formed into a long plate shape and constitute the ceiling fan device 5a, and are disposed in plural on the ceiling part 2 of the vehicle 1 with the longitudinal direction along the longitudinal direction of the vehicle body (only one is shown). This louver 5 is an air outlet κf embedded in the center of the ceiling 2 in the left and right direction.
It is built into the casing of the IL FI 3, and is arranged to face the cross-flow fan 13 that blows the heat-exchanged air into the room.

The louver 5, together with the air conditioner 3, is preferably located between sliding doors 8 and 9 that are arranged to face each other in a circular manner on the right sides 14a and 14b (only one of which is shown) of the vehicle body. Therefore, one vehicle is provided with a number of doors corresponding to the number of sets of doors 8 and 9.

Further, the louver 5 is rotatably supported at one side edge toward the vehicle body. The U end 0111 of the roux I<5 is connected to the geared motor 16 via the link machine side 15, and is driven by this geared motor 16 to rotate and change in the direction of the sleeper as shown by arrow A. In other words, the vehicle body is swung to the right. Then, the louver 5 is displaced within a range of approximately 90 degrees, and its attitude changes from a state in which the tip is directed toward one side 14a to a state in which it is directed toward the other side 15a. There is.

Furthermore, the louver 5 guides the blown air 10 that has undergone heat exchange and is blown toward the interior 4 of the vehicle by the cross-flow fan 13, passes through the grill 17 of the air conditioner 3, and blows it out into the interior 4 of the vehicle. By swinging, the louver 5 blows out air 1.
0 is continuously and periodically changed from one side 14a of the vehicle body to the other side 14b.

Then, when the louver 5 reaches the maximum swing angle as shown in FIG.
A and 14b are formed in the corner, and the guide number '2o is distributed in a curved city shape to which an advertisement 19 or the like is attached, for example.

The louver 5 directs the blown air 10 to the guide 1li.
20, the course of the blown air 10 is changed, and the blown air 10 is caused to flow along the side portion 14a. Then, the louver 5 creates an air curtain effect, and for example, when the door 8 is opened, the doorway 6 is opened.
An air curtain is formed along the entrance/exit 6 and covers the entrance/exit 6.

Further, 21 in FIG. 1 is a control section that controls the swinging of the louver 5. This control unit 21 is configured to manually input door opening/closing signals 22, 23, and these door opening/closing signals 22, 23 cause the right door 8...9...
Which side of the door was opened or closed, and that the opened door was closed after passengers had boarded and alighted. I am starting to judge da. .

Further, the control unit 21 is connected to a position detection sensor 24 such as a microswitch that detects the swing angle of the louver 5. Then, the control unit 21 controls, for example, one side portion 14a.
When the door 8 on the side opens and the door opening/closing signal is manually applied, and the louver 5 reaches its maximum swing angle with its tip facing the one side 14a, the signal is sent via the relay 25. The guard motor 16 is stopped OF'FL and the louver 5 is stopped P>, and the direction in which the blown air 10 is guided by the louver 5 is fixed to one side 14a side, that is, the door opening side.

Further, the control unit 21 is configured to release the guard motor 16 from regulating the ONL louver 5 and restart the swinging of the louver 5 when the doors 8 are closed.

That is, in such a ceiling fan device 5a, Lu I<5
is stopped at the maximum swing angle, and the air curtain 10 is continuously blown out to the opened side of the door 8, thereby creating an air curtain effect in the opened doorway 6. Then, an air curtain is formed at the entrance/exit 6, and the air curtain closes the entrance/exit 6 to prevent air from entering and exiting from the entrance/exit 6.

Therefore, in the ceiling fan device 5a, the air curtain effect prevents outside air from being drawn in, and the amount of outside air flowing in through the open doorway 6 can be significantly reduced. and,
It is possible to prevent sudden temperature changes in the vehicle interior 4 due to the inflow of outside air, prevent discomfort such as heat stress from being caused to passengers located near the doors, and improve comfort.

Furthermore, since the interior of the car can be kept at a comfortable temperature by preventing sudden temperature changes inside the car 4, it is possible to reduce the operating costs of various devices such as the air conditioner 3, , noise can be reduced.

Note that the door 9 on the other side portion 14b (not shown)...
When the louver 5 opens, the guard motor 16 is turned off with a time delay of half the swinging period of the louver 5 when the tip of the louver 5 reaches the maximum swing angle with the tip facing the one side 14a. By doing so, the louver 5 can be swung toward the other side portion 14b and stopped after reaching the maximum swing angle.

Further, for example, two position sensors may be arranged at both ends of the sliding range of the louver 5, and the louver 5 may be placed on each side 14a, 14b.
The reaching of the maximum swing angle on the side may be detected independently.

FIG. 2 shows a second embodiment of the present invention.

+j device 31 is arranged on the guide surface 20 of the main body and inserts an advertisement case 32 made of a transparent plate material into the interior of the vehicle body.
It is installed floating away from the i33. An inlet 34 is located above the ceiling 18 between the advertising case 32 and the surface 33 of the vehicle interior material, and an outlet 35, which has a smaller DFJ port than the inlet 34, is placed above the entrance 6. Air outlet passage 3 located along the edge
6 is formed.

Then, the blowing air 10 guided by the louver 5 (not shown) stopped at the maximum swing angle is sucked into the blowing air passage 36 from the inflow port 34, and
and is discharged from the outflow port 35 substantially directly downward along the inlet/outlet 6. By passing the blown air 10 through the blown air flow path 36, the blown air 10 is
At the same time, the blown air 10 is throttled and accelerated at the outlet 35 to promote an air curtain effect, and an air curtain 37 is actively formed at the open entrance/exit 6.

In addition, in the ceiling fan device 39 of the type shown in the third garden, the fan casing 38 1-1 surrounding the cross-flow fan 13 is swung to function as a louver, and the fan casing 38 guides the blowing air 10. fan casing 3
An air curtain angle that guides the blown air 10 to the substantially true position is set at the swing angle of 8, and when the door 8 opens, the fan casing 38 is stopped at the air curtain angle, and the ceiling part 2 The air curtain 37 may be formed by blowing the air 10 into an air curtain duct 40 formed inside the air curtain.

[Effects of the Invention] As explained above, the present invention provides a louver in the ceiling of a car body that selectively opens and closes doors on either the left or right side, and prevents air from blowing into the car from the ceiling. In a vehicle ceiling fan device that uses a louver to guide the air while changing direction between the left and right sides of the vehicle body, when the door is opened, the louver is guided to the side of the vehicle body on the open side based on the door opening/closing signal that indicates the door opening side. The blown air is temporarily stopped at the maximum swing angle when the blown air is guided, and the blown air is continuously blown to the side surface on the open side of the door and distributed along the side surface on the open side of the door.

Therefore, the present invention has the effect of preventing outside air from entering the vehicle interior and preventing sudden temperature changes from occurring within the vehicle interior.
