Description

  The present invention relates to an elevator apparatus that prevents the passenger from feeling uncomfortable by improving the air environment or restricting the passenger to enter the car when the air environment in the car is deteriorated. About.

  When a passenger gets into the elevator car, the user may feel uncomfortable due to a bad smell in the car. In order to eliminate this discomfort, for example, several methods as described below have been proposed.

  FIG. 5 shows a first conventional example disclosed in JP-A-11-228057. In this example, the odor detector 102 that operates when the bad odor in the car 101 exceeds a predetermined value, the deodorizing device 103 that releases ozone into the car 101, the operation of the odor detector 102, and A deodorizing control device 104 is provided that operates in response to a call from the car 101 and energizes the deodorizing device 103. When the bad odor in the car 101 exceeds a predetermined value, the deodorizing device receives a call from the landing 103 supplies ozone into the car 101. Therefore, it is said that passengers at the landing do not get into the car 101 with a bad odor and that the deodorizing device 103 operates only when necessary, so that power can be saved.

Moreover, in the 2nd prior art example disclosed by Unexamined-Japanese-Patent No. 2001-328786, the photocatalyst activated by light is provided in the elevator apparatus, a cableway, the wall material which comprises a cable car, an internal and external apparatus, and installation objects. By applying it, it is said that air purification, antibacterial, dirt adhesion prevention and cleaning can be facilitated. FIG. 6 is a graph showing test results for evaluating the effects of the second conventional example. That is, an anatase-type titanium oxide coating material is coated on the inner wall surface of a small space (volume: 2 L, material: quartz glass) simulating the inside of a car, dried at 110 ° C. for 30 minutes, and sunlight (ultraviolet light) is placed in the small container. The decomposition characteristics of 500 ppm acetaldehyde were evaluated by irradiation with an intensity of 0.3 to 0.8 mW · cm ² .

  FIG. 7 shows a third conventional example disclosed in Japanese Patent Laid-Open No. 7-157244. The purpose of this example is to completely ventilate the air inside the car 201 without opening any air containing dust from the hoistway into the car 201 and when the door is opened and closed. An air circulation purification device 202 that circulates the air in the passenger car 201 in the width direction of the upper part of the entrance / exit in the elevator car 201 and the air in the passenger car 201 is forced when the door of the elevator device is opened. An air exhaust device 203 for exhausting the air, and opening the air suction port 204 of the air circulation purification device 202 toward the floor surface of the car 201, while the air outlet 205 is directed toward the upper part of the wall surface of the car 201. Open each air intake port 206 of the air exhaust device 203 toward the inside of the car 201, and direct the air outlet 207 toward the door side of the car 201. And then opened.

  As described above, several methods have been proposed in order to prevent the user from feeling uncomfortable due to the bad odor in the car, but each has the following problems.

  In the first conventional example, ozone is released into the car by the deodorizing device. However, when a lot of ozone is released, there is a concern that the human body may be adversely affected. Even if a device or control method that reduces the amount of ozone released below the specified value is installed, there is a risk of releasing a large amount of ozone if it malfunctions or malfunctions. There is. In addition, there are problems such that an extra space is required to attach the deodorizing device and an extra cost is required.

  In the second conventional example, the air is cleaned by applying a photocatalyst to the wall material, the internal and external devices, and the installed parts constituting the elevator apparatus, but it takes 40 minutes until the acetaldehyde is completely removed. It is said that. Therefore, if the cause of the bad odor in the car is temporary, such as the body odor or release of the passenger, the time when the bad odor disappears naturally is shorter than the time to deodorize in this example, There will be almost no effect.

In the third conventional example, an air circulation purification device is provided at the upper part of the entrance / exit to ventilate, but not only does the air circulation purification device require extra cost, but an extra space is needed at the upper part of the entrance / exit. There are problems such as.
Japanese Patent Laid-Open No. 11-228057 JP 2001-328786 A JP-A-7-157244

  The problem to be solved is that the conventional structure for improving the air environment in the car reduces the safety, requires extra cost and space, and efficiently improves the temporary deterioration of the air environment. It is a point that cannot be done.

  The elevator apparatus of the present invention has a door that opens and closes an entrance and exits, and controls a car that loads the passenger and moves up and down, a driving apparatus that drives the car, and the driving apparatus and the door. Control means and air environment detection means or air environment estimation means for detecting or estimating the air environment in the car, wherein the air environment detection means or the air environment estimation means detects or estimates deterioration of the air environment. In this case, at least one of the door opening / closing control method and the car operating method is changed.

  According to the elevator apparatus of the present invention, when it is detected or estimated that the air environment in the car has deteriorated, the door opening / closing control method or the car operating method is changed to change the air in the car. It is possible to prevent the passengers from feeling uncomfortable by improving the vehicle or restricting the passengers from entering the car. According to the present invention, it is possible to efficiently improve the deterioration of the air environment in the car without adversely affecting the human body of the user, without requiring extra cost and space.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a schematic configuration of an elevator apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a relationship between devices of the elevator apparatus shown in FIG.

  In this embodiment, two elevator apparatuses are installed in one bank. In addition, since the two elevator apparatuses have the same structure, the same code | symbol is attached | subjected to the same component.

  In FIG. 1, reference numeral 1 denotes a hoisting machine to which a sheave 2 is attached. By rotating the sheave 2, the rope 3 wound around the sheave 2 is driven in the longitudinal direction. A cage 4 is attached to one end of the rope 3, and a counterweight 5 is attached to the other end. A compensatory 6 is installed at the bottom of the hoistway, and a compensatory rope 7 is wound around the compensatory 6. One end of the compensation rope 7 is attached to the lower part of the car 4, and the other end is attached to the lower part of the counterweight 5.

  One end of a tail cord 8 is attached to the lower part of the car 4. One end of a tail cord wiring 10 is connected to the other end of the tail cord 8 via a junction box 9 attached to the building. The other end of the tail cord wiring 10 is connected to the main controller 11.

  A door 12 that opens and closes the doorway is attached to the car 4, and the door 12 is controlled to open and close by a door control device 13. In addition, the car 4 is provided with a ventilation fan 14 for ventilating the air in the car 4 and a sensor 15 for detecting or estimating the air environment in the car 4. Control lines of the door control device 13, the ventilation fan 14, and the sensor 15 are connected to one end of the tail cord 8. As the sensor 15, for example, a sensor that reacts to a specific component contained in the air, such as an odor sensor or a carbon dioxide concentration meter, or a sensor that detects the state of the air, such as a temperature sensor or a humidity sensor, is used. it can.

  The door control device 13, the ventilation fan 14, and the sensor 15 are connected to the main control device 11 via the tail cord 8, the junction box 9, and the tail cord wiring 10, and can exchange control signals. . Electricity is supplied from the tail cord 8 into the car 4.

  Hall display devices 16 to 18 are installed in the halls on each floor, and these are connected to the main control device 11 via the wiring 19 for the hall display device. The two main control devices 11 are connected by a main control device wiring 20 and are connected to an external monitoring device 22 via an external monitoring device wiring 21. Accordingly, the two main control devices 11 can exchange information with each other and can transmit predetermined information to the external monitoring device 22.

  Next, the relationship between the devices will be described with reference to FIG.

  The main control device 11 includes a hoisting machine control unit 23 and a car equipment control unit 24. The hoisting machine control unit 23 is connected to the hoisting machine 1 via the hoisting machine wiring 25, and the main control device 11 sends the control signal of the hoisting machine 1 from the hoisting machine control unit 23. The operation of the machine 1 can be controlled.

  The car equipment control unit 24 is connected to the door control device 13, the ventilation fan 14, and the sensor 15 through the tail cord wiring 10, the junction box 9, and the tail cord 8, and the main control device 11 is connected to the car. For example, the door 12 of the car 4 can be controlled to open / close, the operation of the ventilation fan 14 can be controlled, and the information detected by the sensor 15 can be taken in via the appliance control unit 24.

  Further, the car equipment control unit 24 is connected to the hall display devices 16 to 18 installed in the halls of the respective floors via the hall display device wiring 19, and the main control device 11 transmits a signal. A predetermined display can be performed on the hall display devices 16 to 18.

  Next, the operation of this embodiment will be described with reference to FIG.

  First, in step S <b> 201, the main controller 11 detects or estimates the air environment in the car 4 based on a signal from the sensor 15. The main controller 11 stores in advance the air environment determination criteria detected or estimated. That is, the level 1 (first level) when the user's body odor or radioactivity is temporarily deteriorated, and the level 2 (second level) when the air environment is deteriorated so as not to occur normally. It is said.

  The main controller 11 determines whether or not the air environment of the car 4 is level 1 or higher in step S202. If NO, no abnormality in the air environment in the car 4 is recognized, so that the processing flow is performed. finish. If the air environment of the car 4 is level 1 or higher in step S202, the process proceeds to step S203.

  If it is determined in step S203 that the air environment of the car 4 is not level 2 or higher, it is determined that the air environment is temporarily deteriorated, the process proceeds to step S204, and the air in the car 4 of another elevator apparatus device is determined. If the environment has not deteriorated, the operation method is changed so that the operation of the car 4 is given priority. In other words, even if the car 4 is called, the next passenger gets into the car 4 whose air environment is temporarily deteriorated by giving priority to the car 4 having a good air environment. Can be limited in advance.

  Next, it progresses to step S205 and it is determined whether the passenger car 4 in which the air environment has deteriorated is stopped. If it is not stopped, the process proceeds to step S206, the door opening / closing control method is changed so as to extend the door opening time after arrival at the final destination floor, and the process proceeds to step S211.

  If the car 4 is stopped in step S205, the process proceeds to step S207 to determine whether the stopped floor is the final destination floor. If it is not the final destination floor in step S207, the process proceeds to step S206, the door opening / closing control method is changed so as to extend the door opening time after reaching the final destination floor, and the process proceeds to step S211.

  If the stopped floor is the final destination floor in step S207, the process proceeds to step S208 to determine whether or not the door is currently open. If the door is open in step S208, the door opening / closing control method is changed to extend the door opening time longer than usual, and the process proceeds to step S211.

  If the door is not opened in step S208, the door is opened, the door opening / closing control method is changed to extend the door opening time, and the process proceeds to step S211.

  In step S211, the control method of the ventilation fan 14 is changed so that the air volume of the ventilation fan 14 is increased when the door is opened.

  As described above, when it is considered that the air environment in the passenger car 4 is temporarily deteriorated due to the body odor or radio of the user, the passenger car 4 is subjected to a series of processes in steps S204 to S211. In addition to restricting the next passenger to get in, the door opening time is extended more than usual after reaching the final destination floor and the air flow of the ventilation fan 14 is increased to smoothly ventilate the passenger car 4 By doing so, the temporary deterioration of the air environment can be improved.

  The final destination floor is as follows. For example, if there are three passengers in the rising car 4, and each destination is on the 4th, 6th, and 7th floors, the 7th floor is the final destination floor. In this case, even if the air environment in the car 4 deteriorates on the way to the final destination floor, the car 4 is not actively ventilated until the final destination floor is reached. This is because priority is given to transporting the passenger to the destination floor more quickly than ventilation of the air in the car 4.

  After ventilating for a predetermined time in step S211, the process proceeds to step S212, where it is determined again whether the air environment in the car 4 is level 1 or higher, and if it is not higher than level 1, the air in the car 4 is Since the environment can be regarded as having returned to normal by ventilation, the processing flow is terminated.

  If the air environment in the car 4 is level 1 or higher in step S212, the air environment could not be improved even after ventilation for a predetermined time, and the car 4 that generates malodor such as animal dung is generated. Since it is highly possible that an abnormality such as being present is occurring, the level is considered to be level 2, and the process proceeds to step S216, where the door is opened.

  If the air environment is level 2 or higher in step S203, it is considered that the air environment in the car 4 has deteriorated so as not to normally occur, and the process proceeds to step S213. In step S213, it is determined whether or not the car 4 is stopped. If not stopped, the process proceeds to step S214, the door is opened after arrival at the final destination floor, the process proceeds to step S217, and the car 4 is suspended.

  When the floor stopped in step S215 is the final destination floor, the process proceeds to step S216, the door is opened, and the process proceeds to step S217. In step S218, the hall display devices 16 to 18 and the car 4 display or announce that the car 4 is at rest. In step S219, the external monitoring device 22 is notified that the air environment in the car 4 is abnormal via the external monitoring device wiring 21, and the predetermined processing is terminated.

  As described above, when it is considered that the air environment in the car 4 has deteriorated so as not to normally occur, the car 4 is put in a rest state by a series of processes of steps S213 to S219, By displaying or announcing in the hall display devices 16 to 18 and the car 4 that the car 4 is at rest, it is possible to restrict the next passenger from getting in. Further, since the external monitoring device 22 is notified that the air environment in the car 4 is abnormal, the manager who has received the notification can rush to the site and quickly remove the cause of the abnormality.

  FIG. 4 summarizes the operation of each device corresponding to the air environment in the car 4 detected or estimated.

  When the air environment in the car is normal, the door opening time, the car operation method, and the strength of the ventilation fan in the car are all normal, and the content of the monitoring signal sent to the outside is `` Normal ”And the announcements in the hall and in the car will be normal.

  If the air environment in the car is temporarily deteriorated due to the body odor or release of the passengers, etc., an operation mode in which the door opening time is made longer than usual and priority is given to the operation of the car of other elevator devices. And activate the ventilation fan strongly. However, the content of the monitoring signal transmitted to the outside is “normal”, and the display in the hall and the announcement in the car are also normal.

  If the air environment in the car is getting worse than would normally happen, the car door remains open, the car is paused, the ventilation fan is activated, and the outside The content of the signal to be transmitted is “abnormal”, the display in the hall is suspended, and the suspension is announced in the car.

  In the above embodiment, the car is paused with the door open. However, this is because priority is given to promoting ventilation. When priority is given to preventing passengers from entering the door, the door is used. The car may be paused with the door closed.

  In the above embodiment, when the air environment in the car deteriorates, both the door opening / closing control method and the car operating method are changed, but only one of them is changed. May be.

  In the above embodiment, when the air environment in the car deteriorates, the control method of the ventilation device, the content of the monitoring signal transmitted to the outside, the content of information provided to the user are changed. Only one or two of them may be changed.

  In the above embodiment, when the air environment in the car is at or above the first level, the other car is given priority for operation, but when the car is called. In addition, the air environment may be improved when a passenger enters the car by delaying the response of the car of the first level or higher than usual.

  Also, in the above embodiment, the air environment of the car has deteriorated to such a degree that it cannot normally occur when the door of the car of the first level or higher is opened for a predetermined time or more and the first level or higher is maintained. However, it may be regarded as such when the first level or higher is continued for a predetermined time or longer.

  In addition, various modifications can be made to the above embodiment without departing from the gist of the present invention.
