Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator equipped with a heating device and particularly suitable for use in cold regions.

(Prior Art) As an elevator equipped with a heating device 4, as shown in FIG. forming and sending
The IA heater 3 and the air supply port 5 are connected by a duct 6, and the 2i wind discharged from the discharge port 3a of the blower heater 3 is blown out from the air supply port 5 into the car 1 through the duct 6, and the inside of the car 1 is blown out. A heating system is known (1977-
No. 149452).

(Problem to be solved by the invention) However, in the conventional configuration in which the air heating unit 113 is arranged on the ceiling 2 and the air supply port 5 is formed at the lower part of the side plate 4, the route of the duct 6 is long. As a result, the heat loss of the warm air flowing through the duct 6 from the discharge port 3a of the air heater 3 to the air supply port 5 increases, and the temperature of the warm air blown from the air supply port 5 into the car 1 decreases. There is a problem with doing so.

Send! If the capacity of A@mm3 is increased, it is possible to maintain the temperature of the hot air blown out from the air supply port 5 at a high temperature, but such a measure increases the operating power of the heater 3, making it uneconomical. Not only that, but problems such as noise also occur.

It is also possible to suppress heat loss by providing the air supply port 5 at the top of the side plate 4 and shortening the path of the duct 6, but in such a case, the hot air blown from the air supply port 5 may Basket 1
It directly hits the upper body of the passenger inside, causing discomfort to the passenger. Furthermore, when warm air blows out from the air supply port 5 at the top of the side plate 4, the warm air simply drifts to the upper part of the vehicle ζ1.
It does not flow to the lower part of the car 1, and as a result, the entire temperature distribution inside the car 1 becomes uneven, making it difficult to create a comfortable heated space.

This invention was made with attention to such problems, and an object of the present invention is to provide an elevator equipped with a heating device that can efficiently heat the inside of a car while maintaining a uniform temperature distribution throughout the car. The purpose is to

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, this invention provides a blower heater under the floor of the car and an air supply port in the lower part of the side of the car. An exhaust hole is provided in the ceiling of the car, and a duct connects and communicates the discharge port of the blower heater with the air supply port, and f[ discharged from the discharge port is passed through the duct to the air supply port. The air is blown out into the car.

(Function) Since the air feeder ff1Q1 is installed under the floor of the car, and the air supply port is formed at the bottom of the side of the car, the two are placed close to each other, which shortens the duct route. Therefore, heat loss of the warm air flowing through the duct is suppressed, and the hot air discharged from the outlet of the air supply chamber is efficiently blown into the car from the air supply port at almost the same temperature.

In addition, since the air supply vent is located at the bottom of the side of the car, the 1ffl does not hit the passenger's upper body directly.
Therefore, there is no possibility of causing discomfort to passengers. The 1ffi blown out from the air supply port gradually rises from the lower part of the car to the upper part based on heat convection and flows out smoothly from the exhaust hole, resulting in the overall temperature distribution inside the car. The temperature is almost uniform, resulting in a comfortable heated space.

(Example) Hereinafter, the embodiment 1581 of this invention will be explained.

A first embodiment is shown in FIG. 1, where 11 is a car, and air heating IM11 is installed on both sides of the lower surface of the floor 12 of this car 11.
3.13 is installed. In addition, air supply ports 16.degree. 16 are formed in the lower portions of both sides of the car 11, for example, in the bookcase 15.15 that connects the folding board 14 and the floor 12. The blower heater 13゜13 has suction ports 13a, 1 for sucking air.
3a and discharge ports 13b, 13b for discharging hot air, and the discharge ports 13b, 13b and the air supply port 16.16 are connected by a duct 17.17 so as to communicate with each other.

On the other hand, a plurality of exhaust holes 19 are formed in the center of the ceiling 18 of the car 11. And these exhaust holes 1
A cover 20 is attached above the exhaust holes 19 . . . to prevent foreign matter such as dust from entering the car 11 from the exhaust holes 19 .

In such a configuration, when the blower heater 13°13 is operated, temperature is discharged from the discharge ports 13b, 13b, this warm air flows through the duct 17.17, and the air supply port 16.16
It is blown out into the car 11.

Here, the ventilation @ cell 6113.13 is the floor 1 of the car 11.
The air supply port 16.16 is provided on the bottom surface of the car 11.
Because it is formed in the middle book 15.15 at the bottom of the side of the
These two are placed close together, so that the duct 17.17
The path of the hot air flowing through the duct 17.17 is therefore reduced, and the heat loss of the hot air flowing through the duct 17.17 is suppressed.
It was discharged from the discharge ports 13b and 13b! ! The waste is efficiently transferred from the air supply port 16, 16 to the car 11 at almost the same temperature.
It squirts inside.

Further, since the air supply ports 16, 16 are arranged at the lower part of the side of the car, the hot air does not directly hit the upper body of the passenger, and therefore does not cause discomfort to the passenger. Then, the parts blown out from the air supply ports 16, 16 gradually rise from the lower part to the upper part in the car 11 based on heat convection, and smoothly flow out from the exhaust holes 19...
Therefore, the entire temperature distribution inside the car 11 becomes almost uniform, resulting in a comfortable heated space.
