Description

Description: TECHNICAL FIELD The present invention relates to an elevator car with a cooling / heating device including a device for cooling / heating the interior of an elevator car.

[Prior Art] Conventionally, there has been a canopy provided with an air conditioner on a canopy of an elevator cab in order to cool and heat the elevator cab.

As a conventional elevator car with this type of air conditioner,
There is one shown in FIG.

FIG. 2 is a vertical cross-sectional view showing a conventional elevator car with an air conditioner.

In the figure, 1 is an elevator car, 2 is an elevator car room, 3 is a canopy of the elevator car 1, 4 is a wall, 5 is a floor, and 6 is a width provided between the lower end of the wall 4 and the floor 5. It is a tree. Reference numeral 7 denotes a suspended ceiling provided below the canopy 3 of the elevator car 1 at a predetermined interval.
Together with this, it forms a double ceiling. Reference numeral 8 denotes an air conditioner provided on the top of the canopy 3, which is provided at a position avoiding a rescue exit for rescue of passengers in an emergency. Reference numeral 9 is a box that covers the cooling and heating device 8, 10 is a suction port of the cooling and heating device 8, 11 is a blower housed inside the cooling and heating device 8, and 12 is an outlet. 13 is a partition plate that separates the intake side and the outlet side of the cooling and heating device 8, 14 is the canopy 3, the wall 4, the suspended ceiling 7,
A suction side passage is formed on the suction side by the partition plate 13, and a discharge side passage 15 is also formed on the discharge side.

A is a flow of suction air sucked from the inside of the elevator cab 2 to the cooling / heating device 8, and B is a flow of discharge air which is cooled or heated by the cooling / heating device 8 and is then sent to the elevator cab 2.

Next, the flow of air in the conventional elevator car with a heating and cooling system configured as described above will be described.

When the air conditioner 8 is operating, the air in the elevator cab 2 passes through the suction side passage 14 and the air conditioner 8
After being sucked into the inside and cooled or heated, the discharge side passage 15
Is returned to the elevator cab 2 again. That is, since the door of the elevator car 1 is frequently opened and closed and the air inside and outside the elevator car room 2 is replaced, the elevator car 1 is of a circulation type in order to increase the thermal efficiency.

In addition, after the door of the entrance / exit is closed, air inside / outside the elevator cab 2 enters / exits through a slight gap such as a gap between the door and the entrance / exit pillar or a gap between the lower end of the wall 4 and the skirting board 6, Ventilation with the outside air is performed.

By the way, the air conditioner 8 is installed at a position avoiding the emergency rescue exit provided on the canopy 3 of the elevator car room 2. However, when the elevator car 1 is small and the installation space is limited, According to the technique described in Japanese Utility Model Publication No. 57-34228, it is also possible to mount the rescue outlet so that it also serves as a part of the peripheral wall of the discharge side passage of the cooling and heating device.

[Problems to be Solved by the Invention] Since the conventional elevator car with air-conditioning system is configured as described above, passengers can be locked in the elevator car room 2 for a long time while the door is closed due to a failure or the like. Then, the air conditioner 8 is a circulation type, and ventilation is insufficient with a small gap such as a gap between the door of the entrance and exit and a pillar of the entrance or exit, or a gap between the lower end of the wall 4 and the skirting board 6, Passengers were sometimes uncomfortable. In particular, when a large number of passengers are on board, not only the unpleasant odor is filled up, but also dirty air is sucked and oxygen shortage may cause a headache.

Other prior arts include Japanese Utility Model Publication No. 51-29470 and Japanese Utility Model Publication No. 2-26084.

In the technology disclosed in Japanese Utility Model Publication No. 51-29470, an air conditioner is installed on the upper part of the car, and a member that can be closed in a gap between the car and the car door and between the car and the skirting board. Disclosed is a technique in which each member is provided and the gap is closed by the member only during the operation period of the cooling / heating device, and the air from the cooling / heating device is circulated without opening the outside air intake. However, as mentioned above, when there are a large number of passengers,
Not only is it filled with an unpleasant odor, but it may inhale dirty air or cause a headache due to lack of oxygen, which is highly dangerous because it improves the airtightness.

Further, the technique disclosed in Japanese Utility Model Laid-Open No. 2-26084 discloses an elevator ventilation device that operates a ventilation fan when it detects that a predetermined time has elapsed after the car stopped and no calls were made. But this kind of technology
This is to obtain the timing of the ventilation of the car, and the cooling / heating efficiency is reduced when the cooling / heating device is operating, so it cannot be used.

Therefore, the present invention provides an elevator with an air conditioner that does not give discomfort to passengers by providing sufficient ventilation even when the passenger is locked in the elevator cab for a long time while the air conditioner is operating. The challenge is to provide a basket.

[Means for Solving the Problems] An elevator car with an air conditioner according to the present invention has a suction-side passage that guides the air in the elevator car room to the air conditioner and the air that has been heat-exchanged by the air conditioner into the elevator car room. Provided in the discharge-side passage that leads and the discharge-side passage, the elevator door is operated when the door is closed for more than the door closing time during normal operation, and the outside air merges with the heat-exchanged air. And a blower for supplying the air into the elevator cab.

[Operation] In the present invention, a cooling / heating device is provided on the canopy of the elevator cab, and the door of the elevator is closed during normal operation in the discharge passage that guides the air that has undergone heat exchange by the cooling / heating device into the elevator cab. It is operated when the door is closed for more than a time period, and since the outside air joins the heat-exchanged air, the elevator door is closed for more than the normal operation time. In the case of 1, the fresh air of the outside air is taken into the discharge side passage by the blower provided in the discharge side passage and is further supplied into the elevator cab.

[Embodiment] An embodiment of the present invention will be described below with reference to FIG.
