Description

The present invention relates to an elevator that provides cooling and ventilation within the car.

2. Description of the Related Art Conventionally, an elevator is known in which an "internal air circulation type cooler" is installed in a car (Patent Document 1). This elevator is equipped with an "internal air circulation type cooler," which eliminates the need to cool the air inside the hoistway, which tends to become hot, so it is possible to improve cooling efficiency. However, the "internal air circulation type cooler" does not ventilate the inside of the car because it only takes in the air inside the car and blows it out into the car.

On the other hand, there is known an elevator equipped with an air conditioner capable of switching between introducing outside air and circulating inside air (Patent Document 2). This elevator has a duct for sucking air in the car, a duct for sucking air in the hoistway, and a motor damper for switching the use state of these two ducts as ducts for sucking air into the air conditioner. In this elevator, in order to improve the cooling efficiency when the doors are closed, a duct is used to suck in the air inside the car and circulate the inside air for air conditioning. Then, in order to prevent the heat from the landing from penetrating into the car, air conditioning is performed using a duct that draws air from the hoistway. Thus, in this elevator, the inside of the car is cooled and ventilated by switching between the introduction of outside air and the circulation of inside air.

By the way, in an elevator that switches between outside air introduction and inside air circulation, outside air is introduced when the door is open, so the temperature of the air blown out from the air conditioner is higher than in the case where the inside circulation is performed when the door is open. Further, in this elevator, if the intake of outside air is reduced in order to prevent the temperature of the air blown out from the air conditioner from rising, there is a risk that the amount of ventilation that matches the size of the car cannot be ensured.

An object of the present invention is to provide an elevator that achieves both cooling efficiency and ventilation volume.

The elevator of the present invention includes a car, an internal air circulation type air conditioner for cooling the inside of the car, introduction of air from the outside of the car into the car, and introduction of air from the inside of the car to the outside of the car. a ventilator for at least one of exhausting air.

According to this configuration, circulation of inside air in the car by the air conditioner is maintained, so that the temperature of the air blown out from the air conditioner can be kept low, and the inside of the car can be ventilated by the ventilator.

Further, in the elevator, the air conditioner has an air outlet for blowing cool air, and the ventilator has an air inlet for sucking in air while discharging air from the inside of the car to the outside of the car. , The air intake of the ventilator may be located farther from the door of the car than the air outlet of the air conditioner.

According to such a configuration, the air flows from the car door toward the ventilation device, that is, from the entrance of the car toward the back, so that the ventilation performance is ensured. Cold air from is retained in the cage.

Further, in the elevator, the ventilator may operate intermittently.

According to such a configuration, it is possible to suppress the influence on the cooling efficiency by adjusting the operation time of the ventilation device to the extent that the amount of ventilation matched to the size of the car can be secured.

As described above, according to the present invention, it is possible to provide an elevator that achieves both cooling efficiency and ventilation volume.

FIG. 1 is a schematic diagram showing the arrangement of a ventilator and an air conditioner in an elevator car according to this embodiment. FIG. 2 is a plan view showing the arrangement of the ventilator and the air conditioner in the car.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

The elevator 1, as shown in FIG. and a ventilator 4 for at least one of exhausting air out of the empty car 2. The elevator 1 also includes a car door 21 (a door of the car 2) that opens and closes the doorway 20 of the car 2. As shown in FIG. The car door 21 is a door for getting in and out of the car 2 .

The car 2 runs in the hoistway of the building in which the elevator 1 is installed. 2, the car 2 includes, for example, a front panel 22 provided with an entrance 20, a back panel 23 arranged on the back side of the car 2, a front panel 22 and a back panel. a pair of side panels 24, 25 connecting 23;

The ventilator 4, for example, only discharges air from the car 2 to the outside of the car 2 (exhaust operation). Therefore, it is possible to prevent the hot air in the hoistway from directly hitting the user, and to prevent the cooling feeling from being spoiled. Also, the ventilator 4 is arranged outside the car 2 , for example, above the car 2 .

Specifically, the ventilator 4 has a ventilation intake 40 that is an intake of the ventilator 4 and a ventilation outlet 41 that is an outlet of the ventilator 4 . Also, the ventilation inlet 40 and the ventilation outlet 41 take air in and out from the ceiling of the car 2 . A ventilation inlet 40 and a ventilation outlet 41 are provided on the ceiling of the car 2 . In addition, in the elevator 1 of the present embodiment, one ventilation inlet 40 and one ventilation outlet 41 are provided, but at least one of them may be provided in plurality.

Specifically, the ventilator 4 operates intermittently for a preset time corresponding to the rated air volume so that the required ventilation volume in the car 2 can be secured. More specifically, the ventilator 4 operates intermittently for 5 minutes and then stops for 10 minutes, thereby performing ventilation operation for 20 minutes per hour and securing the ventilation rate in the car 2. .

When the ventilator 4 performs only the exhaust operation, the user does not directly feel the wind from the ventilator 4, so even if the ventilator 4 operates intermittently, it is possible to prevent the wind from blowing and stopping. It is possible to prevent the user from mistaking it for failure.

The air conditioner 3 is a cooler that draws in the air in the car 2 and blows out cooled air. Further, the air conditioner 3 is arranged outside the car 2, for example, above the car 2. As shown in FIG.

Specifically, the air conditioner 3 has an air-conditioning suction port 30 that is a suction port for sucking the air in the car 2 and an air-conditioning outlet 31 that is a blowing port for blowing cold air. Also, the air-conditioning suction port 30 and the air-conditioning outlet 31 take air in and out from the ceiling of the car 2 . The air-conditioning inlet 30 and the air-conditioning outlet 31 are provided on the ceiling of the car 2, for example. In the elevator 1 of the present embodiment, one each of the air-conditioning suction port 30 and the air-conditioning blowing port 31 is provided, but at least one of them may be provided in plurality.

The air conditioner 3 cools, for example, the air sucked in through the air conditioning suction port 30 (the air that flows from the floor side of the car 2 toward the ceiling and further flows above the ceiling of the car 2 toward the back side). Also, the air cooled by the air conditioner 3 is blown out through the air conditioning outlet 31 (flowing above the ceiling of the car 2 to the inner side and further from the ceiling of the car 2 toward the floor side).

The air conditioner 3 adjusts the air temperature in the car 2 by, for example, adjusting both the temperature of the blown cold air and the volume of the blown cold air. Further, the air conditioner 3 adjusts the air temperature inside the car 2 according to the temperature of the sucked air, for example.

In the elevator 1 of the present embodiment, the air conditioner 3 enhances the cooling performance (sets the temperature of the cool air to a low level or increases the air volume of the cool air) at the operation timing of the ventilator 4 . As a result, it is possible to prevent the temperature inside the car 2 from rising even during ventilation by the ventilation device 4 . In this case, for example, the ventilator 4 transmits an operation signal to the air conditioner 3 when operating, and the air conditioner 3 adjusts the cooling performance according to the operation signal.

In the elevator 1 of this embodiment, as shown in FIG. 2, the ventilation suction port 40 of the ventilation device 4 is arranged at a position farther from the car door 21 than the air conditioning outlet 31 of the air conditioner 3 is. Specifically, the ventilation inlet 40 and the ventilation outlet 41 are positioned away from the car door 21 . More specifically, the ventilation intake 40 is arranged along the back panel 23 facing the car door 21 .

According to the elevator 1 described above, circulation of inside air in the car 2 by the air conditioner 3 is maintained, so that the temperature of the air blown out from the air conditioner 3 can be kept low, and the inside of the car is ventilated by the ventilator 4. be able to.

According to the elevator 1 of the above embodiment, the operation time of the ventilation device 4 is adjusted to the extent that the ventilation volume can be secured according to the size of the car 2, and the ventilation volume is secured by intermittently operating the ventilation device 4. It is possible to suppress the influence on the cooling efficiency while maintaining the temperature.

Further, in the elevator 1 of the above embodiment, the ventilator 4 is positioned farther from the car door 21 than the air conditioning outlet 31 of the air conditioner 3 . Therefore, the air flows from the car door 21 toward the ventilation device 4, that is, from the doorway 20 of the car 2 toward the back, so that the ventilation performance is ensured. Cool air from 3 is retained in car 2 .

It should be noted that the elevator of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, some of the configurations of certain embodiments can be deleted.

Although the ventilator 4 only discharges (exhausts) air from the car 2 to the outside of the car 2, the ventilator 4 may only introduce (intake) air from the outside of the car 2 into the car 2, Both exhaust and intake may be performed. When the ventilator 4 performs both exhaust and intake, for example, the elevator 1 may include both the ventilator 4 for exhaust and the ventilator 4 for intake, or may switch between the exhaust operation and the intake operation. A ventilator 4 may be provided.

Although the ventilator 4 operates intermittently for a preset period of time, it can be operated intermittently by changing the operation time according to the temperature of the air taken in by the air conditioner 3. good. In this case, for example, the ventilator 4 may obtain information about the temperature of the air sucked into the air conditioner 3 from the air conditioner 3 .

Further, the ventilator 4 may perform intermittent operation according to opening and closing of the car door 21 . In this case, for example, when the car door 21 is open, outside air is likely to flow into the car 2 from the landing through the doorway 20 of the car 2, so the ventilation device 4 may be stopped.

Furthermore, the ventilation device 4 shortens the operating time during traveling on high floors where the air temperature in the hoistway is relatively high, and lengthens the operating time while traveling on low floors where the air temperature in the hoistway is relatively low. may

Although the ventilator 4 is operated intermittently, it may be operated constantly.
