ある。[Problem to be solved by the invention [1] The conventional elevator car ventilation system is configured as described above and circulates the air in the hoistway into the car.
In the summer, the temperature θ2 inside the car approaches the temperature θ in the hoistway, and the temperature θ2 in the air-conditioned elevator landing hall approaches θ.
This creates a large difference between the air temperature θ2 and the air temperature inside the car, and this creates a problem in that passengers feel uncomfortable when boarding and alighting between the landing and the car. This invention was made to solve the above-mentioned problems, and by bringing the temperature inside the car closer to the temperature in the landing hall, it is possible to create an elevator that allows passengers to get on and off the car without discomfort. The purpose is to obtain a cage ventilation system. [Means for Solving the Problems] An elevator car ventilation system according to the present invention has a ventilation means for exhausting air inside the car to the hoistway of the elevator,
The detection means is operated when the car arrives at the landing, stops, and the car door is opened, and this operation energizes the control means to operate the ventilation means.

ことができろ。In the elevator car ventilation system of this invention, when the car stops at the landing of each floor and the door of the car opens together with the door of the landing, a large amount of air from the landing hall is sucked into the car by the ventilation means, and the door closes. By reducing or eliminating the amount of air exhausted inside the car by the above-mentioned ventilation means, and by reducing or eliminating the amount of air exchanged between the hoistway and the inside of the car, the temperature θ2 inside the car can be reduced to The temperature should be kept close to θ3 and not close to the temperature inside the hoistway.

FIG. 1 is a partially vertical side view of an elevator equipped with a car ventilation system according to an embodiment of the present invention. In Fig. 1, the same reference numerals as in Fig. 4 indicate the same or equivalent parts, and 2 is a ventilation fan that is a ventilation means provided at the top of the car 1, and the ventilation fan 2 discharges the air inside the car 1 to the hoistway. It is configured as follows. Further, numeral 6 is a temperature sensor installed at an appropriate position inside the car 1, such as the upper part of the car 1, and 7 is a temperature sensor installed at an appropriate position on the landing hall side of each floor, such as the upper part of the three-sided landing frame 4. In addition, a detection means (not shown) for detecting that the door 3 of the car 1 of this embodiment is opened together with the door 5 of the landing, and the temperature sensor 6.7 and the detection means operate to supply air by the ventilation fan 2. A control device (not shown) is provided to increase or decrease the air volume. Next, the operation of the car ventilation system according to the above embodiment will be explained with reference to the flowchart shown in FIG. When the ventilation system is operated and car 1 is stopped at a landing on a certain floor as shown in Figure 1, with door 3 of car 1 and door 5 of the landing open, the air temperature θ2′ inside car 1 and the landing The control device determines whether the temperature difference with the hall air temperature θ3 is a predetermined value of 600 or more based on the detection signal of the temperature sensor 6.7, and if the temperature difference is more than the predetermined value, the control device controls the ventilation fan. 2 increases the amount of displacement from the inside of the car 1. When the displacement increases, a large amount of cold air is sucked into car 1 from this hall when the landing hall is air-conditioned, and the air inside car 1 is exchanged by the necessary amount, reducing the temperature inside car 1 to θ2.
′ becomes lower. Next, when the door 3 of the car 1 closes together with the door 5 of the landing and the car 1 starts running, the detection means detects this and reduces the exhaust volume from the inside of the car 1 to the hoistway by the ventilation fan 2. The state continues while car 1 is running. Therefore, the temperature θ2 in the car 1 is maintained close to the temperature θ3 in the landing hall (and sufficiently lower than the temperature θ in the hoistway), and passengers who board the car 1 do not feel uncomfortable. When it arrives at the landing on the landing floor, it stops, doors 3 and 4 open (and the above operation is repeated 9 times, and the temperature inside car 1 is 600 or more higher than the temperature θ3 in the landing hall by a predetermined value. in case of,
Cold air is blown into car 1 from the landing hall. That is, in the car ventilation system according to this embodiment, as shown in FIG. 3, when the doors 3 and 5 are open when the car 1 is stopped, the exhaust volume by the ventilation fan 2 is large, and when the doors 3 and 5 are closed when the car 1 is running, the exhaust volume is large. The exhaust volume by the ventilation fan 2 is reduced, and the temperature inside the car 1 can be maintained close to the temperature in the landing hall.Although the above embodiment has been described for cooling, this invention also applies to heating the hoistway. When the temperature is low, the temperature inside the car can be brought close to the temperature in the landing hall.Furthermore, the ventilation means according to the present invention may increase or decrease the exhaust volume by appropriate means such as increasing or decreasing the rotation speed of the electric motor of the ventilation fan.
Although the temperature sensor of the embodiment may not be provided, by using the temperature sensor as in the embodiment, it is possible to prevent the exhaust volume from increasing more than necessary, which is useful for energy saving. Further, in the above embodiment, a small amount of ventilation is performed when the door is closed, such as while the car is running, but in the present invention, when the door is closed, the ventilation means may be stopped and the car may not be ventilated.

がある。As explained above, according to the present invention, the air inside the car is exhausted to the hoistway by the ventilation means (ζ), and this exhaust amount is reduced when the car stops at the landing and the car door opens together with the landing door. These doors can be closed or removed when the car is running, so the temperature inside the car can be maintained at a temperature close to the temperature in the landing hall, and the car can be closed. This has the effect of providing an elevator car ventilation system that allows passengers inside the car to get on and off the car without discomfort.
