Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an elevator car equipped with an air-conditioning device for heating and cooling the inside of the car.

[Conventional technology]

4 to 6 show an elevator car equipped with a conventional air-conditioning system as shown in, for example, Japanese Utility Model Publication No. 57-34228. In the figures, 1 is the elevator car, 2 is an outer ceiling plate, and 3 is a denotes an inner ceiling plate having an inner emergency rescue door 4; 3a denotes an intake port; 5 denotes an air-conditioning device disposed above the outer ceiling plate 2; 6 and 7 denote intake and exhaust ducts; 8 denotes an upper surface of the peripheral wall of the intake duct 6. This door 8 is an external emergency rescue door that also serves as a part of the branch exhaust duct section 7 where the exhaust duct 7 branches into two.
It is provided between a and 7a and is fixed with screws 9 to the upper surface of the outer ceiling board 2 so that it can be removed upward.

According to the elevator car heating and cooling system configured as described above, the air inside the elevator car 1 is normally pumped through the air intake port 3a provided on the side surface of the inner ceiling plate 3.
Air is guided from an intake duct 6 surrounded by outer ceiling panels 3, 2 and an outer emergency rescue door 8 to an air conditioning device 5, cooled and warmed by this air conditioning device 5, and then passed through an exhaust duct 7.
The air is blown out into the car 1 as cold air and warm air.

In addition, in order to rescue passengers in the car in the event of an emergency due to a breakdown during elevator operation, remove the outer emergency rescue door 8 by removing the screws 9 from the top surface of the outer ceiling board 2, and remove the outer emergency rescue door 8. The inner emergency rescue door 4 provided correspondingly is opened inside the car 1.

[Problem that the invention seeks to solve]

Since the conventional elevator car heating and cooling system is constructed as described above, it is necessary to remove the numerous screws 9 of the outer ceiling panel 2 of the outer emergency rescue door 8 during maintenance and inspection of the air conditioning system or when rescuing passengers.
It was difficult to complete the work in a short period of time. In addition, when the work space on the top of the car is small, such as in a small elevator, there are problems such as difficulty in finding a place to temporarily place the above-mentioned emergency rescue door 8 and suction/exhaust ducts 6 and 7 even if they are removed. It was hot.

This invention was made to solve the above-mentioned problems, and it is possible to quickly open an external emergency rescue door provided on the top surface of the outer ceiling board of the car during maintenance or inspection of the air conditioning system or when rescuing passengers. To provide a heating and cooling system for an elevator car which can perform the following tasks and does not affect work even when the work space on the top surface of the car is small, such as in a small elevator.

[Means for solving problems]

In the elevator car heating and cooling system according to the present invention, the outside emergency rescue door, which also serves as the intake and exhaust ducts of the heating and cooling system and a part of the surrounding wall of the intake duct, is made of a flexible material that can be expanded and contracted.

[Effect]

In this invention, the air-conditioning system's intake and exhaust ducts and the outside emergency rescue door, which also serves as a part of the intake duct peripheral wall, are made of a flexible material that can be expanded and contracted. Alternatively, the external emergency rescue door can be compressed and shifted to one side without removing it completely from the external ceiling board. Furthermore, since it is made of a flexible material that can be expanded and contracted, it can be applied to air-conditioning devices of various sizes.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, 1 is an elevator car, 2 is an outer ceiling panel, 3 is an inner ceiling panel having an emergency rescue door 4 inside the cage, 3a is an air intake port, 5 is an air conditioning system,
Reference numerals 6 and 7 indicate suction and exhaust ducts, which are made of a flexible material having a corrugated shape that can be expanded and contracted. In particular, the exhaust duct 7 is made of a flexible material formed into a bellows tube shape.

Reference numeral 8 denotes an external emergency rescue door that also serves as a part of the upper surface of the peripheral wall of the intake duct 6. This rescue door 8 is made of a flexible material that can be expanded and contracted like the intake duct 6, and there are two exhaust ducts 7. It is provided between the exhaust duct parts 7a and 7a, which are composed of bellows pipes branched into two, and can be folded upward toward the air-conditioning device 5 side, and one end is pivotally attached to the upper surface of the outer ceiling board 2. There is.

In the elevator car heating and cooling system configured as described above, the dirty air inside the elevator car 1 is normally pumped through the air intake port 3a provided on the side surface of the inner ceiling plate 3.
Surrounded by outer ceiling panels 3, 2 and outer emergency rescue door 8,
The air is sucked into an air intake duct 6 having these as a peripheral wall, and is introduced from the air intake duct 6 into the air conditioning device 5 where it is cooled and warmed. Then, cold air or hot air is blown out from the air conditioning device 5 into the elevator car through the bellows-shaped exhaust duct 7. In addition, in order to rescue passengers in the car in the event of an emergency caused by a breakdown during elevator operation, one end of the outer emergency rescue door 8 can be folded upward from the outer ceiling panel 2 and moved toward the cooling/heating device 5. At the same time, the inner emergency rescue door 4 disposed corresponding to the outer emergency rescue door 8 is opened inside the car 1.

In addition, in the above embodiment, the intake and exhaust ducts and the external emergency rescue door are constructed using a flexible material having a corrugated shape that can be expanded and contracted, but the invention is not limited to this. Of course, the same effect can be obtained even if flame-retardant cloth is used as the material.

〔Effect of the invention〕

As described above, according to the elevator car heating and cooling system according to the present invention, the external emergency rescue door that forms part of the peripheral wall of the intake and exhaust ducts and the intake duct is made of a flexible material having a stretchable corrugated gate,
Because it can be folded freely in an accordion style,
When the outside emergency rescue door is opened during maintenance and inspection of the air conditioning system or when rescuing passengers in an emergency during elevator operation, it can be done easily and in an extremely short time. Moreover, it is of course applicable to air-conditioning equipment of various sizes, and since there is no need to completely remove the intake and exhaust ducts from the outer ceiling board, there is no problem in the work even if the work space is small. Furthermore, since the exhaust duct is made of a flexible material that can be expanded and contracted, excellent effects can be achieved, such as the ability to freely design the outlet for blowing air from the air conditioning system into the elevator car.
