  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a specific description will be given of the control for operating or pausing the ion generator by counting the number of call registrations within a predetermined time and determining the magnitude of the call registration with a predetermined set value. It is also possible to control the ion generator by calculating the number of users instead of counting the number of call registrations within a certain period of time and determining whether the number of users within the certain period of time is a predetermined set value. It can be realized in the same way.

  FIG. 1 is an overall configuration diagram of an elevator with an ion generator, and FIG. 2 shows the configuration of its control unit. The elevator apparatus shown in FIG. 1 includes a car 5 that moves up and down in a hoistway via a rope, a control unit 2 built in a control panel 1 that controls the raising and lowering of the car 5, a device 3 that registers a landing call, and a car. Control panel 4, air cleaner 6 including an ion generator, blower fan 10, maintenance switches 8 a to 8 c, external input devices 9 a to 9 c, and signal lines for communicating signals from the car and the landing 7, etc.

  The control unit 2 in FIG. 2 includes a use frequency determination unit 2a to which a landing call 3 is input, an operation control unit 2b having an input of maintenance switches 8a to 8c and an output for controlling the air purifier, and an external input device 9a. Are composed of a data part 2c inputted by .about.9c and other control parts related to the elevator drive.

  The blower fan 10 is operating during car operation. In a state where the car door is closed, air in the car is convected to promote negative ion diffusion of the air cleaner 6 with an ion generator. Moreover, a plate capable of changing the wind direction is attached to the blower fan 10 so that the ions are circulated in the car when the door is closed, and the wind direction is used to suppress the outflow of ions from the car when the car door is open. By controlling the wind direction according to the open / closed state of the car door, ions can be efficiently circulated in the car.

  In this embodiment, the blower fan 10 is installed on the ceiling behind the car 5 (opposite the car door), but the blower fan 10 is provided near the car door to send out curtain-like air, and the car door It may be used for the purpose of suppressing ion outflow from the cage when it is open.

  When the number of people who use the elevator is small, since the number of bacteria brought into the passengers is small, the necessity of operating the ion generator of the air cleaner 6 is low, so the operation is stopped. On the other hand, when the number of people who use the elevator is large, the number of bacteria brought into the passenger increases. Therefore, the effect of sterilization and deodorization is required, the ion generator of the air cleaner 6 is operated, and negative ions are supplied into the car.

  FIG. 3 shows power control of the ion generator, and a stop period T2 is provided after an operation period T1 in which the ion generator is operated for a predetermined time. The operation period T1 is determined with reference to the time for the negative ions generated from the ion generator to reach the car, and the stop period T2 is determined with reference to the time during which the effect of the negative ions in the car is not impaired. In this embodiment, the operation period T1 is 10 minutes and the pause period T2 is 10 minutes.

  Hereinafter, a specific control method will be described with reference to the flowcharts in FIG.

  FIG. 4 shows an overall flowchart of the control unit 2 according to the present invention. In step E10, the control unit 2 is activated by turning on the power or restarting. In step E20, initial processing is executed as initial processing of the control unit 2.

  In step E30, the process proceeds to operation control input processing. Here, signals necessary for elevator operation control such as the position of the car are input and output. In steps E40 and E50, car calls and landing calls are input / output, and in step E60, an operation mode is selected. In step E70, the operation control of the air cleaner is performed using the result in step E60. In step E80, the elevator activation process is executed and the elevator operates.

  As described above, steps E30 to E80 are repeatedly executed at predetermined time intervals until the power is turned off or a program abnormality occurs. Next, air cleaner operation control (step E70) and usage frequency determination (step E70e) will be described in detail.

  FIG. 5 shows a flowchart of air cleaner operation control in step E70 of FIG. Start at step E70a. In step E70b, the operation mode is determined. This operation mode is selected by the operation mode selection in step E60 of FIG. Here, if it is the control operation mode, the process proceeds to Step E70k, and if it is not the control operation mode, the process proceeds to Step E70c.

  In step E70c, it is determined whether or not it is during construction. This is determined by the data under construction of the data 2c shown in FIG. If construction data is input, the process proceeds to step E70k. If construction data is not input, the process proceeds to step E70d.

  In step E70d, it is determined whether the operation is a maintenance operation. That is, if any one of the maintenance switches 8a to 8c is turned on, the process proceeds to step E70f. If any of the maintenance switches 8a to 8c is not turned on, the process proceeds to step E70e.

  In step E70e, it is determined whether or not the vehicle is in a quiet state based on a flowchart of usage frequency determination based on the number of hall calls shown in FIG. That is, if the usage frequency is low in the quiet state, the process proceeds to step E70g. If the usage frequency is not high and the usage frequency is high, the process proceeds to step E70i.

  In step E70f, it is determined whether or not forced operation data is input to the data portion 2c. If it has been input, the process proceeds to step E70h. If it has not been input, the process proceeds to step E70i.

  If it is determined in step E70g that the air cleaner is operating, the process proceeds to step E70j, and the operation of the air cleaner is continued. When the air cleaner is not operating, the process proceeds to step E70k. In step E70h, the air cleaner 6 performs a continuous operation. When the maintenance switches 8a to 8c are released or the forced operation data 2c is cleared, the air cleaner 6 stops the continuous operation and proceeds to Step E701.

  In step E70i, the air cleaner is operated for 10 minutes (operation period T1) and then stopped for 10 minutes (stop period T2). After stopping for 10 minutes, the process proceeds to Step E701.

  In step E70j, the current operation of the air cleaner 6 is not stopped depending on the use situation, but is operated during the operation period T1. In step E70k, the air purifier is stopped and the process proceeds to step E701. In step E701, this process is terminated.

  FIG. 6 is a use frequency determination flowchart for determining whether or not it is a quiet state in step E70e of FIG. First, the process starts at step E70ea.

  Next, in step E70eb, the number of hall calls 3 per unit time 1 (here 20 minutes) is counted. Here, if it is less than or equal to the set value 1 (two here), it is determined that the use frequency is low, that is, it is in a quiet state, and the process proceeds to step E70ed. On the other hand, if it is larger than the set value 1, the process proceeds to Step E70ec.

  In step E70ec, the number of hall calls 3 per unit time 2 (here, 60 minutes) is counted. If it is less than or equal to the set value 2 (here, 6), the determination is suspended and the process proceeds to step E70ef. If larger than the set value 2, the process proceeds to step E70ee. It is judged that the usage frequency is high, that is, it is not in a quiet state.

  The determination hold in the above means that the state before the determination is continued. That is, when there are three to six landing calls, the quiet state is continued if the previous state is a quiet state, and the non-free state is continued if it is not a quiet state.

  In step E70ed, the air cleaner is instructed to pause. In step E70ee, a start permission signal for the air purifier is output. In step E70ef, this process is terminated.

  FIG. 7 is a flowchart showing detailed control of the air purifier operation (step E70i) of FIG. 5, and is for performing intermittent operation. Start at E70ia. In step E70ib, it is determined whether the operation of the air cleaner is commanded. If the operation of the air cleaner is commanded, the process proceeds to step E70id, and if not, the process proceeds to step E70ic.

  In step E70ic, it is determined whether a command to stop the air cleaner is issued. If the pause command has not been issued, the process proceeds to step E70if, and if it has been issued, the process proceeds to step E70ie. In step E70ie, it is determined whether a predetermined time 2 (10 minutes in this case) has elapsed after the air purifier pause command. If the predetermined time 2 has elapsed, the process proceeds to step E70if. Otherwise, the process proceeds to step E70ig and the air purifier pause command is continued.

  In step E70id, it is determined whether a predetermined time 1 (here, 10 minutes) has elapsed after the air cleaner operation command. If the predetermined time 1 has elapsed, the process proceeds to step E70ig. Otherwise, the process proceeds to step E70if, and the air cleaner operation command is continued.

  In the above series of flowcharts, only the operation command is output for the control of the air cleaner 6, but the operation signal or failure signal of the air cleaner 6 may be received to monitor the state of the air cleaner 6. .

  Each set value and each predetermined time are different parts depending on the performance of the air cleaner. A better effect can be obtained if it is set after sufficiently confirming the performance of the air purifier.

  The forced operation data 2c is provided so that the operation of the air cleaner can be visually confirmed during maintenance operation. Therefore, other operation confirmation means may be provided, such as displaying on the maintenance device after being taken into the control unit 2.

  Construction data 2c is used to stop the air purifier 6 during maintenance work, so that construction workers do not inhale dust during building temporary use, and no operation is required during construction. It is.

  Further, as described above, if the number of elevator users is calculated instead of counting the number of hall calls in FIG. 6, the control of the ion generator according to the number of elevator users can be performed in the same manner.
