Description

[Detailed explanation of the invention] This invention relates to a heating system for vehicles such as trains.

Conventionally, the first heating system for commuter trains was
The item shown in Figure 2 was found. In the figure, 1 is a vehicle body, 2 is a door, 3 is a chaise longue seat arranged in the vehicle body 1, and 4 is a heating device disposed at the bottom of each seat 3. Referring to FIG. 2, reference numeral 5 denotes a riser board provided in the space between the seat 3 and the floor surface 6 of the vehicle body, and the riser board 5 has a large number of ventilation holes 7. Reference numeral 8 denotes a reflector plate of the heating device having a U-shaped cross section, and the open side of the reflector plate 8 is disposed opposite to the riser plate 5. Reference numeral 9 denotes a heating element provided within the reflector plate 8. Heat radiated from the heating element 9 warms the seat 3, and radiant heat is emitted into the interior of the vehicle from the ventilation hole 7 of the riser 5 to perform heating.

By the way, in commuter trains, generally one or two heating devices 4 of the same capacity are installed for one seat 3. In other words, for one vehicle, for example
14 to 16 heating devices of 700W/unit are often installed (in this example, 8 units of 1.4KW/unit are installed). However, the heating capacity of 10 to 11 KW per vehicle mentioned above will keep the inside temperature of the car at a comfortable temperature of 18 to 22 KW during the cold season.
It is insufficient to maintain the temperature at ℃. In other words, during the heating season, there is a limited amount of time when the heating capacity is insufficient, such as early in the cold season or late at night when there are few passengers, but although each passenger radiates heat of about 100W, the fewer passengers, the more contribution is made to heating. do not. In addition, when there are few passengers, the amount of ventilation when opening and closing the doors is large, resulting in large heat loss. Therefore, in view of the above points, increasing the heating capacity is effective in commuting trains where doors are opened and closed frequently and there are many doors, and heat loss due to ventilation increases, so increasing the heating capacity is more effective than increasing energy consumption. There were drawbacks such as a lack of

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above.By increasing the heating capacity of a specific seat compared to the heating capacity of other seats, it can be heated early in the morning or late at night with a small heating capacity. The purpose of the present invention is to provide a heating system for a vehicle that allows comfortable heating.

An embodiment of this invention will be described below with reference to the drawings. In Figures 3 and 4, 1 is the vehicle body, 2, 2a,
2b is a door, 3 is a seat of a settee, 4 is a heating device installed at the bottom of the seat 3, and 10
11 is a specific seat sheet that is a part of the seat sheet 3 provided on one side of the vehicle body 1, and 11 is this seat sheet 10.
The heating device installed at the bottom of the
The heating capacity is larger than that of the heating device 4 shown in FIG. In FIG. 4, reference numeral 5 denotes a riser board installed in the space between the seat 10 and the floor surface 6 of the vehicle body, and has a large number of ventilation holes 7. Reference numeral 8 denotes a reflector plate of the heating device having a U-shaped cross section, and the open side of the reflector plate 8 is disposed opposite to the riser plate 5 . Reference numeral 12 denotes a heating element provided within the reflector plate 8. Heat radiated from the heating element 12 warms the seat 10, and radiant heat is emitted into the interior of the vehicle from the ventilation hole 7 of the riser 5 to perform heating. Note that the heating device 4 for the seat 3 is the second heating device.
It is the same as the one shown in the figure.

Next, the operation will be explained. When the heating devices 4 and 10 are energized, the interior temperature of the specific seat 10 and its surroundings becomes higher rapidly than that of the other seats 3. Therefore, if the inside of the car is divided into C and D as shown by the dashed-dotted lines in Figure 3, the inside of the car in the C side zone will be hotter than the D side zone.
If door 2 is kept closed and door 2 is located further away from the C-side zone, heat loss in the C-side zone can be reduced.

In the heating system of this invention, by distinguishing the color of a specific seat 10 from the color of other seats 3, the existence of the seat 10 can be made clear, and the color of the specific seat 10 can be clearly identified. By making it possible to switch the heating capacity of the heating device 11 to the heating capacity of another seat 3, it is possible to avoid heating the inside of the car excessively during times and hours when the high-temperature zone is unnecessary. Although the heating device has been described as a system in which heat generated from a heating element is reflected by the reflector plate 8, the heat generated may be blown into the vehicle interior through the ventilation hole 7 of the riser board 5 using an air blower.

As described above, according to this invention, in a vehicle heating system in which a heating device is disposed below the seat of a chaise longue, the heating capacity of the heating device of a specific seat can be made larger than the heating capacity of other seats. As a result, passengers can sit on a specific seat that is hotter than other seats, especially in the early morning or late at night, and therefore the interior of the vehicle can be effectively heated with a small heating capacity. In addition, since certain seats can heat up quickly, they have the advantage of being able to quickly and comfortably heat the seat.
