Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator apparatus installed in a building having a plurality of floors, a method of controlling the elevator apparatus, and a building equipped with this elevator apparatus.

[0002]

2. Description of the Related Art In conventional elevator systems for high-rise buildings, the atmospheric pressure in the car changes rapidly as the car moves up and down. There is a problem in that the pressure of the passenger's middle ear cavity does not follow the changes in the atmospheric pressure in the car, resulting in ear dizziness or dizziness due to pressure on the eardrum.

As a countermeasure against this, a method of applying pressure to the entire building or to dividing the building into blocks to eliminate the pressure change due to the difference in altitude is considered, for example, Japanese Patent Laid-Open No. 4-2135.
Methods such as 86 and Japanese Patent Laid-Open No. 5-97366 have been proposed.

Further, as in Japanese Patent Publication No. 57-54436, the atmospheric pressure in the car is repeatedly changed many times during the traveling of the car to stimulate the Eurasian canal and promote the adjustment of the air pressure inside and outside the eardrum. A method of balancing the pressure in the middle ear cavity has also been considered.

However, the former method of pressurizing a building requires a large-scale pressurizing device, is costly, and is difficult to realize in many cases. Further, the latter method of positively balancing the pressure in the middle ear cavity is not necessarily effective because the individual difference is large.

In super high-rise buildings with a height of 500 m or 1000 m, the pressure difference between the ground and the top floor becomes significant unless the inside of the building is pressurized. The pressure difference from the floor exceeds 100 hPa. On the other hand, in order to shorten the traveling time between the upper floor and the lower floor as much as possible, the lifting speed of the elevator device tends to increase.
Ultra-high speed elevators of about 0 m / min have also been put to practical use, and the speed of elevators will further increase as the number of buildings increases. When moving a large height difference at a high speed, it is feared that passengers in the elevator car may suddenly experience discomfort such as a deafness or dizziness at a certain elevation speed or higher.

[0007]

SUMMARY OF THE INVENTION According to the present invention, the passengers of an elevator hear when a large height difference is moved at a high speed with the increase in the height of a building and the speeding up of an elevator apparatus installed therein as described above. It was made in view of the problem that the risk of causing discomfort such as clogging and dizziness increases rapidly.The purpose is to increase the elevator level even when the pressure difference due to the altitude difference between the upper floor and the lower floor is large. It is an object of the present invention to provide an elevator apparatus, a method for controlling the elevator apparatus, and a building that do not cause passengers to feel uncomfortable without lowering the lifting speed.

[0008]

According to the elevator apparatus of the present invention, a car and means for raising and lowering the car in the hoistway are provided, and the air pressure in the car is adjusted. Atmospheric pressure adjusting means and a control signal for gently changing the atmospheric pressure in the car from the departure floor pressure to the arrival floor floor pressure between the departure and arrival of the car. It is characterized in that it is provided with control means for sending to the adjusting means.

In the control method for the elevator apparatus according to the present invention, the air pressure in the car is adjusted from the pressure of the departure floor to the air pressure of the floor to be arrived between the departure and arrival of the car. It is characterized by slowly changing to.

The building of the present invention comprises a plurality of floors, hoistways formed through these floors, and an elevator apparatus having a car that can be raised and lowered in the hoistways. , Air pressure adjusting means for adjusting the air pressure in the car and the air pressure in the car between the departure and arrival of the car should be gradually changed from the air pressure of the departure floor to the air pressure of the floor to be arrived. And a control means for sending a control signal for changing to the atmospheric pressure adjusting means.

[0011]

According to the above construction, the atmospheric pressure in the car is adjusted to be almost the same as the atmospheric pressure in the arrival floor when the door is opened upon arrival, so a large pressure change occurs when the door is opened in the arrival floor. Therefore, it is possible to eliminate the occurrence of discomfort such as an ear jam for passengers of the elevator without receiving it.

Further, since the atmospheric pressure change in the car during elevator ascent / descent is performed gently (for example, at an average, substantially constant rate), it is possible to mitigate the rapid atmospheric pressure change due to the change in the ascending / descending speed. It is possible to obtain the maximum ascending / descending speed while suppressing the occurrence of discomfort such as stuffiness and dizziness of passengers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator apparatus, a method of controlling the elevator apparatus and a building having the same according to the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a schematic configuration diagram of an elevator apparatus and a building in which the elevator apparatus is installed according to the first embodiment of the present invention. FIG. 2 shows an elevator apparatus according to the first embodiment of the present invention. It is explanatory drawing for demonstrating a control method.

A car 11 which is supported by a wire rope 3 and moves up and down inside a hoistway 1 provided in a building 2 having a plurality of floors 10 is a door 11 for the car 11 (hereinafter referred to as a door). It is configured to have an airtight structure when closed. The air-tight structure of the car 11 is a rubber-filled structure such as a rubber filling structure around the door, around the destination instruction panel (control panel), and the seams (joints) of the car, compared to the conventional car. The ventilator is configured so that it can be hermetically closed by opening and closing a shutter or the like.

Further, the car 11 is provided with an air pressure controller 12 composed of, for example, a compressor (air compressor) for adjusting (pressurizing or depressurizing) the air pressure inside the car 11.
Further, the car 11 is provided with an atmospheric pressure measuring device 13 for measuring the atmospheric pressure inside the car 11, and the atmospheric pressure regulator 12 and the atmospheric pressure measuring device 13 are electrically connected via a controller 14. There is. Here, the pressure regulator 12 is suitable for a reciprocating compressor or the like that is small in size and excellent in responsiveness and pressure control accuracy, and in the pressure measurement device 13, the pressure is relatively accurately measured in units of 1 hPa. What can be measured is desirable.

The controller 14 is also electrically connected to a destination indication panel 15 provided in the car 11, and according to the control procedure shown in FIG. The control is performed so that the air pressure in the car 11 is gently adjusted during the period from immediately after the door is closed at the floor (abbreviated as the floor) to immediately before the door at the arrival floor (hereinafter abbreviated as the arrival floor) is opened.

That is, the destination instruction panel 15 is used to drive the car.
When the 11 arrival floors are designated, the controller 14 calculates the altitude difference H between the departure floor and the arrival floor based on the departure floor number information and the arrival floor number information, and then based on this altitude difference H. Then, the pressure difference ΔP between the departure floor and the arrival floor is calculated by the controller 14. The pressure difference ΔP can be easily calculated by using, for example, a height-measurement formula.
According to P380 of 1993, it is given by the following formula.

[0018]

[Equation 1]

However, ΔP: atmospheric pressure difference (hPa), H: altitude difference
(m) The above equation (1) has sufficient accuracy even if it is approximated by the following equation as long as the altitude difference is about 1000 m.

ΔP = 0.123 H (2) where ΔP: atmospheric pressure difference (hPa), H: altitude difference (m) The controller 14 changes the atmospheric pressure from the altitude difference based on the above formula (1) or (2). It has a conversion function to the difference, and
Calculates the estimated atmospheric pressure value P1 at the arrival floor by adding the calculated atmospheric pressure difference ΔP between the departure floor and the arrival floor to the atmospheric pressure inside the car at the time of departure (pressure P0 at the departure floor).

Further, the controller 14 is based on the floor number information of the departure floor, the floor number information of the arrival floor, and the predetermined ascending / descending speed pattern of the car 11 from the door closing at the departure to the door opening at the arrival. The lifting time T of is calculated. Next, the average atmospheric pressure change amount is calculated by dividing the atmospheric pressure difference ΔP between the departure floor and the arrival floor calculated above by the ascending / descending time T.

The controller 14 controls the atmospheric pressure adjuster 12 so that the atmospheric pressure in the car 11 changes gently according to the average atmospheric pressure change amount. Therefore, the air pressure in the car 11 does not change suddenly, and is adjusted by the air pressure adjuster 12 so that it changes gently on average between the door closing at departure and the door opening at arrival. It

FIGS. 3 and 4 show changes in the atmospheric pressure in the car when the air pressure is adjusted by the elevator apparatus according to the first embodiment of the present invention and when the conventional atmospheric pressure control is not performed, at the time of falling and at the time of rising. Each case of time is shown.
In FIGS. 3 and 4, the characteristic change indicated by the broken line relates to the conventional elevator, and the characteristic change indicated by the solid line relates to the elevator according to the first embodiment of the present invention.

Since the car does not have an airtight structure and the atmospheric pressure is not controlled in the conventional elevator system, the car internal pressure is proportional to the altitude of the car, and the maximum atmospheric pressure is reached when the car reaches the maximum lifting speed. The change (atmospheric pressure change gradient) becomes abrupt, and at this time, the passenger feels the most (strongly) discomfort such as stuffiness and dizziness. That is, the broken lines in FIGS. 3 and 4 show changes in the atmospheric pressure in the elevator car, but the car gradually accelerates from the time of closing the door when it descends or rises, and then reaches the maximum speed. Slowly decelerates and stops, and the door opens. It takes a relatively long time to accelerate and decelerate, so the time to move at maximum speed is short,
The change in atmospheric pressure (rate of change in atmospheric pressure) per unit time is large.

On the other hand, in the elevator apparatus according to the first embodiment of the present invention shown by the solid lines in FIGS. 3 and 4, the traveling speed of the car is gentle from the time when the door is closed when the car descends or rises, as in the conventional case. After accelerating and reaching the maximum speed, the vehicle slowly decelerates and then stops to open the door, but the car 11 is kept airtight, and the air pressure inside the car 11 is between the time the door is closed and the time it is opened. Since the control is performed so as to change on average (approximately at a constant rate), the maximum value of the change in atmospheric pressure per unit time can be suppressed to be extremely small compared to the conventional case.

That is, the internal atmospheric pressure of the car 11 in the elevator apparatus according to the first embodiment of the present invention is the time zone from the closing of the doors until the car starts to move up and down to reach the maximum hoisting speed, and the car. The air pressure is adjusted on average even during the time period immediately before the vehicle decelerates, stops, and opens the door on the arrival floor, that is, before and after the maximum ascent / descent speed is reached. Therefore, the atmospheric pressure change gradient can be significantly reduced compared to the conventional elevator car. The time required to go up and down at the maximum hoisting speed is roughly 1/2 to 1/3 or less of the actual hoisting time from closing the door at departure to opening the door at arrival, depending on the altitude difference. Therefore, according to the present embodiment, the gradient of atmospheric pressure change can be reduced to 1/2 to 1/3 or less as compared with the conventional case.

As described above, according to the first embodiment, the car 11
Even if the ascending / descending speed of the car increases, the air pressure inside the car 11 is adjusted during the time period before and after the maximum ascending / descending speed is reached and the changes in air pressure are averaged (changed at a nearly constant rate). It is possible to suppress the gradient of pressure change. Therefore, a sudden change in atmospheric pressure does not occur, and it is possible to suppress discomfort of passengers such as stuffiness and dizziness. (Modification) FIGS. 5 and 6 are for explaining a modification of the present invention and correspond to the characteristic diagrams of FIGS. 3 and 4.

In the first embodiment, the air pressure inside the car 11 is adjusted so that the air pressure inside the car 11 changes on average from immediately after the door is closed to immediately before the door is opened. It was controlled by 12. However, this atmospheric pressure control method is not limited to that shown in the first embodiment.

That is, in the conventional elevator system, the gradient of atmospheric pressure change becomes the largest at the maximum moving speed of the car, but the gradient of atmospheric pressure change does not pose a problem in a range where passengers do not feel uncomfortable. Further, as shown in the first embodiment, the average change in atmospheric pressure is not always the most comfortable control method for passengers. Therefore, as shown in FIG. 5 or FIG. 6, the atmospheric pressure change gradient in the vicinity of the starting and stopping points of the car 11 may be increased or decreased as compared with other portions, or the atmospheric pressure change may be omitted although not shown. It is also possible to alternately repeatedly pressurize and depressurize within a minute range without performing the operation gently (smoothly). It is desirable that such a control pattern of the atmospheric pressure change gradient be appropriately determined and controlled in consideration of various factors such as experimentally determining the passenger's riding comfort. (Second Embodiment) FIGS. 7 and 8 show a second embodiment of the present invention.

The second embodiment is different from the above-mentioned first embodiment in that atmospheric pressure measuring devices 16 are provided in the respective boarding / alighting halls of a plurality of floors 10 and are electrically connected to the controller 14. . That is, in the first embodiment, the atmospheric pressure difference is estimated (calculated) from the altitude difference between the departure floor and the arrival floor, but in the second embodiment, the atmospheric pressure measuring device 16 is installed in the boarding / alighting hall of each floor 10. Since it is provided, it is possible to directly measure the atmospheric pressure of the arrival floor when the arrival floor is instructed and determined by the instruction panel. Therefore, the first to estimate the barometric pressure of the arrival floor
The accuracy of the atmospheric pressure on the arrival floor can be improved as compared with the embodiment.

As shown in FIG. 8, when the destination instruction panel 15 indicates the arrival floor, the control method by the controller 14 in the second embodiment is such that the departure floor number information, the arrival floor number information, and the advance floor information. The ascending / descending time is calculated from the set ascending / descending speed, at the same time the atmospheric pressure measurement value at the arriving floor is input from the atmospheric pressure measuring device 16 at the arriving floor, and the average atmospheric pressure change amount is based on the atmospheric pressure difference with the car internal pressure at the time of departure Is determined.

According to the average atmospheric pressure change amount, the atmospheric pressure regulator 12 is controlled by the controller 14 from the door closing at the time of departure to the door opening at the time of arrival.
To control the internal pressure of the car 11. As described above, since the relaxed atmospheric pressure change gradient similar to that in FIGS. 3 and 4 can be obtained according to the average atmospheric pressure change amount, it is possible to suppress the passenger's discomfort such as a stuffed ear and dizziness as in the first embodiment. Can be achieved.

In this second embodiment, a plurality of floors 10
The atmospheric pressure measuring device 16 is provided in each of the boarding / alighting halls, but the arrangement of the atmospheric pressure measuring device 16 is not limited to this. In other words, it is not necessary to place it in, for example, an indoor part other than the boarding / alighting hall of the floor 10 or to arrange a barometric pressure measuring device on each floor without fail. By arranging measuring devices, the atmospheric pressure measured by the atmospheric pressure measuring devices representing these two or more floors is regarded as the atmospheric pressure of each of those floors and controlled, and the number of atmospheric pressure measuring devices is reduced. You can also

As shown in the above-described modification, the atmospheric pressure control may be performed in accordance with FIGS. 5 and 6 or other control in consideration of passenger comfort. (Third Embodiment) FIGS. 9 and 10 show a third embodiment of the present invention.

The present embodiment differs from the above-mentioned embodiments in that the car 11 is not provided with an atmospheric pressure measuring device, but an atmospheric pressure measuring device 17 is provided at a predetermined position of the building 2. Then, other configurations are similar to those of the first and second embodiments, and the car
11 is airtight when the door is closed, and is electrically connected to the air pressure controller 12 that controls the air pressure inside the car 11 and the air pressure controller 12 during the time from the door closing at departure to the door opening at arrival. A controller 14 is provided.

As shown in FIG. 10, the control method of the controller 14 is such that when the destination floor is instructed by the destination instruction panel 15 in the car 11, the controller 14 informs the controller 14 of the floor number of the departure floor and the floor number of the arrival floor. Is transmitted, and the hoisting time from the door closing on departure to the door opening on arrival is calculated from the preset hoisting speed.

At the same time, from the altitude difference H0 between the floor where the atmospheric pressure measuring device 17 is placed and the departure floor and the altitude difference H1 between the floor where the atmospheric pressure measuring device 17 is placed and the arrival floor, the measurement explained in the first embodiment is performed. Calculate the atmospheric pressure difference using Equation (1) or Equation (2) based on the high formula, and add it to the measured value of the atmospheric pressure measuring instrument 17 to calculate the estimated value of the atmospheric pressure at the departure floor and the estimated value of the atmospheric pressure at the arrival floor. To do.

The controller 14 further determines the average pressure change amount based on the ascending / descending time and the estimated pressure value on the departure floor and the estimated pressure value on the arrival floor, and determines the time from the departure door closing to the arrival door opening. The atmospheric pressure inside the car 11 is controlled using the atmospheric pressure regulator 12. By performing the control in this manner, the relaxed gradient of the atmospheric pressure change can be obtained as in FIGS. 3 and 4, so that the passenger's deafness, dizziness, etc. can be prevented as in the first and second embodiments. Discomfort can be suppressed.

In FIG. 9, the barometer 17 is installed on the lowest floor of the building, but it may be installed on any floor in the building. In the third embodiment, since it is not necessary to provide the atmospheric pressure measuring device 17 for each of the cars 11, the number of atmospheric pressure measuring devices can be reduced when a large number of cars are provided.

In the third embodiment as well, as shown in the above-mentioned modification, the atmospheric pressure control may be performed by referring to FIGS. 5 and 6 or other control in consideration of the passenger's riding comfort. Although the controller 14 is installed in the car in each of the first, second, and third embodiments,
Of course, the same function can be obtained even if the car 11 is installed outside the car 11 as long as it is electrically connected to the barometric pressure regulator 12 of each car 11 and the destination indication panel 15 and the barometric pressure measuring device 13. .

In the above description, as means for raising and lowering the car 11 of the elevator apparatus in the hoistway 1, means for supporting and hoisting the wire rope 3 is shown, but instead of this, linear means is used. The car 11 may be moved up and down using a motor or the like, and various modifications can be made without departing from the scope of the invention.

[0042]

As described above, according to the present invention, even if the ascending / descending speed of the car increases, the gradient of the atmospheric pressure change in the car is controlled so as to be gentle. Even if the elevator device moves up and down at a high speed without causing any trouble, it is possible to suppress the discomfort of passengers such as stuffiness and dizziness.
