DETAILED DESCRIPTION OF THE INVENTION

[0009] The following detailed description will be given with reference to the drawings. Duplicate descriptions will be simplified or omitted as appropriate. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0010] Embodiment 1 FIG. 1 is a diagram showing an example of an elevator system in which the air conditioning control device according to the first embodiment is used. The elevator system includes a car 1 and a counterweight 2. The car 1 moves up and down in a hoistway 3. The hoistway 3 is a space extending up and down in a building. The car 1 and the counterweight 2 are suspended in the hoistway 3 by a rope 4. FIG. 1 shows an example of an elevator system using a 1:1 roping method.

[0011] The rope 4 is wound around a drive sheave 6 of a hoisting machine 5. The hoisting machine 5 drives the car 1. That is, the car 1 moves up and down depending on the direction in which the drive sheave 6 rotates. The counterweight 2 moves in the hoistway 3 in the direction opposite to the direction in which the car 1 moves. A control device 7 controls the hoisting machine 5. That is, the movement of the car 1 is controlled by the control device 7.

[0012] 1 shows an example in which the hoisting machine 5 and the control device 7 are provided in a machine room 8 above the hoistway 3. The hoisting machine 5 and the control device 7 may also be provided in the hoistway 3. The hoisting machine 5 may also be provided at the top of the hoistway 3 or in a pit in the hoistway 3.

[0013] A cab 9 is formed in the car 1. The cab 9 is a space for passengers to ride in. An air conditioner for the cab 9 is not provided in the car 1. In the example shown in FIG. 1, an air conditioner 11 for the cab 9 is provided in the counterweight 2. The air conditioning control device used in this elevator system will be described in detail below.

[0014] Fig. 2 is a diagram schematically illustrating the air conditioning control device in embodiment 1. Fig. 3 is a diagram for explaining the functions of the air conditioning control device. In addition to air conditioner 11 provided on counterweight 2, the air conditioning control device further includes blowing device 12, intake device 13, driving device 14, control device 15, and thermometer 16.

[0015] The air conditioner 11 generates at least one of cold air and warm air. It is preferable that the air conditioner 11 be able to generate both cold air and warm air. Below, an example in which the air conditioner 11 is used as a cooler will be described. That is, the air conditioner 11 generates cold air.

[0016] The blowing device 12 is a device for blowing out cool air generated by the air conditioner 11. The blowing device 12 is supported by the air conditioner 11. The blowing device 12 may be supported by the counterweight 2. The intake device 13 is a device for taking in the cool air blown out from the blowing device 12 into the car room 9. The intake device 13 is provided in the car 1. FIG. 4 is a perspective view showing an example of the blowing device 12 and the intake device 13.

[0017] The blowing device 12 has a connection part 21 that protrudes from the counterweight 2 toward the car 1 on the horizontal projection plane. An air outlet 22 for blowing out cool air from the air conditioner 11 is formed in the connection part 21. The air outlet 22 opens in the elevator shaft 3 so as to face the car 1 side on the horizontal projection plane. The connection part 21 of the blowing device 12 is movable so as to move toward and away from the car 1 on the horizontal projection plane. In a preferred example, the connection part 21 is part of a duct connected to the air conditioner 11. The air outlet 22 is formed at the tip of the duct.

[0018] The intake device 13 has a connection part 23 that protrudes from the car 1 toward the counterweight 2 on a horizontal projection plane. An intake port 24 that leads to the car room 9 is formed in the connection part 23. The intake port 24 opens in the hoistway 3 so as to face the counterweight 2 side on a horizontal projection plane. When the car 1 is disposed at a specific position P where the connection part 21 and the connection part 23 are at the same height, the intake port 24 faces the air outlet 22. Figures 2 and 4 show a state in which the car 1 is disposed at position P.

[0019] The intake device 13 may further include a guide portion 25. The guide portion 25 is provided on the connection portion 23. The guide portion 25 is disposed so as to extend from the connection portion 23 toward the counterweight 2 on the horizontal projection plane.

[0020] The guide portion 25 is a member for guiding the connection portion 21 to the connection portion 23 when the connection portion 21 approaches the connection portion 23. In the example shown in FIGS. 2 and 4, the guide portion 25 is cylindrical. The central axis of the guide portion 25 is aligned with the central axis of the cylindrical connection portion 23. One end of the guide portion 25 is provided at the tip portion of the connection portion 23. The inlet 24 opens inside the guide portion 25. Furthermore, the diameter of the guide portion 25 increases with increasing distance from the connection portion 23. As a result, a guide surface 26 for guiding the connection portion 21 to the connection portion 23 is formed in the guide portion 25.

[0021] The drive device 14 drives the blowing device 12. Specifically, the drive device 14 drives the blowing device 12 so that the connection portion 21 moves toward and away from the connection portion 23 on a horizontal projection plane. The drive device 14 is, for example, a motor. The drive device 14 is supported by the air conditioner 11. The drive device 14 may also be supported by the counterweight 2.

[0022] The control device 15 controls the drive device 14. Specifically, the control device 15 controls the drive device 14 to bring the connection part 21 into contact with the connection part 23 when the car 1 is stopped at position P. The control device 15 is supported by the air conditioner 11. The control device 15 may also be supported by the counterweight 2. As another example, the control device 15 may be provided as one function of the control device 7. A cable 17 for power supply and control is connected between the control device 15 and the air conditioner 11 and the drive device 14.

[0023] The thermometer 16 is provided in the car 1. The thermometer 16 measures the temperature of the car room 9. Information on the temperature measured by the thermometer 16 is transmitted to the control device 15.

[0024] The operation of the air conditioning control device will be described below with reference to Fig. 5 to Fig. 7. Fig. 5 is a flowchart showing an example of the operation of the air conditioning control device in embodiment 1. Specifically, Fig. 5 shows the operation flow of control device 15.

[0025] The control device 15 determines whether or not a start condition for performing air conditioning management has been met (S101). The start condition is set in advance. As an example, in summer, the start condition is met when the temperature measured by the thermometer 16 exceeds a first set temperature. As another example, the start condition is met when a standby state with no calls for car 1 continues for a certain period of time.

[0026] When the start condition is met (Yes in S101), an operation command C is sent from the control device 15 to the control device 7 (S102). The operation command C is a command to stop the car 1 at position P. When the control device 7 receives the operation command C from the control device 15, it controls the hoist 5 to stop the car 1 at position P. It is preferable that the position P is the position when the car 1 stops at a specific landing. As an example, the position P is the position when the car 1 stops at a landing on the first floor.

[0027] When the car 1 stops at position P, the connection part 23 is positioned at the same height as the connection part 21. Also, the intake port 24 faces the air outlet 22. When the car 1 stops at position P, the control device 15 controls the drive device 14 to bring the connection part 21 closer to the connection part 23 (S103).

[0028] Figures 6 and 7 are diagrams for explaining the operation of the air conditioning control device. Figures 6 and 7 are diagrams corresponding to Figure 4. Figure 6 shows a state in which connection portion 21 is approaching connection portion 23. Figure 7 shows a state in which connection portion 21 is in contact with connection portion 23.

[0029] As shown in Fig. 6, in S103, connecting portion 21 moves in the direction indicated by arrow D1. At this time, if the central axis of connecting portion 21 does not exactly coincide with the central axis of connecting portion 23, connecting portion 21 will come into contact with guide surface 26 of guide portion 25 before coming into contact with connecting portion 23. As connecting portion 21 is guided by guide surface 26, connecting portion 21 is displaced in the direction indicated by arrow D2 so that the central axis of connecting portion 21 coincides with the central axis of connecting portion 23. As blowing device 12 continues to be driven by drive device 14 after connecting portion 21 comes into contact with guide surface 26, connecting portion 21 and connecting portion 23 come into contact with each other with the central axis of connecting portion 23 coinciding with the central axis of connecting portion 23, as shown in Fig. 7.

[0030] When the connection part 21 contacts the connection part 23, the control device 15 operates the air conditioner 11 (S104). As a result, the cool air generated by the air conditioner 11 passes through the blowing device 12 and the intake device 13 and is supplied to the car room 9.

[0031] When the supply of cool air to the car 9 starts in S104, the control device 15 determines whether the temperature of the car 9 has reached the second set temperature (S105). The second set temperature is set in advance. The second set temperature is a temperature lower than the first set temperature. The determination in S105 is made based on the temperature measured by the thermometer 16. When the temperature of the car 9 has reached the second set temperature, the determination in S105 is Yes.

[0032] If the temperature of the car room 9 has not reached the second set temperature (No in S105), it is determined whether a call has been registered for car 1 (S106). For example, a call for car 1 is registered in the control device 7. When the control device 7 registers a call for car 1, it transmits registration information indicating that the call has been registered to the control device 15. When the control device 15 receives the registration information from the control device 7, it determines Yes in S106.

[0033] If the determination in S105 or S106 is Yes, the control device 15 stops the air conditioner 11 (S107). As a result, cool air is no longer supplied to the car room 9. Furthermore, if the determination in S105 or S106 is Yes, the control device 15 controls the drive device 14 to separate the connection part 21 from the connection part 23 (S108). As a result, the connection part 21 is positioned so that the blowing device 12 and the intake device 13 do not interfere with each other even when the car 1 moves up and down.

[0034] In the example shown in this embodiment, cool air from the air conditioner 11 can be sent to the car 9 with the connection part 21 of the blow-out device 12 and the connection part 23 of the intake device 13 in contact with each other. Therefore, in the example shown in this embodiment, the cool air blown out from the air outlet 22 of the connection part 21 can be efficiently guided to the car 9.

[0035] Other examples in which the present air conditioning control device can be used will be described below. If possible, the air conditioning control device may be used in combination with the following examples.

[0036] 4, the connection part 21 of the blowing device 12 may include a magnet 21a. In such a case, the connection part 23 of the intake device 13 is made of a magnetic material. In this example, the connection part 21 can be attracted to the connection part 23 in S103. Furthermore, in order to prevent the magnet 21a from being attracted to the guide part 25 in S103, it is preferable that the guide part 25 is made of a non-magnetic material.

[0037] A magnet may be provided at the connection portion 23 of the intake device 13. In this case, the connection portion 21 of the blowout device 12 is made of a magnetic material.

[0038] In the present embodiment, an example has been described in which intake device 13 is provided with guide unit 25. As another example, blowout device 12 may be provided with a guide unit having the same function as guide unit 25. In such a case, when connection unit 23 approaches connection unit 21, connection unit 23 is guided to connection unit 21 by the guide unit.

[0039] In this embodiment, an example has been described in which the guide portion 25 is a cylindrical member. The shape of the guide portion 25 is not limited to a cylindrical shape. The portion of the guide portion 25 that can be disposed directly above or directly below the connection portion 21 may be formed smaller than the other portions. In this example, even if the car 1 moves upward or downward in the state shown in FIG. 7, for example, the connection portion 21 can climb over the guide portion 25, preventing damage to the blowing device 12 and the intake device 13.

[0040] In this embodiment, an example has been described in which the drive device 14 drives the blowing device 12. As another example, the drive device 14 may drive the intake device 13. In such a case, the drive device 14 is supported by the car 1. Furthermore, the drive device 14 drives the intake device 13 so that the connection portion 23 approaches and moves away from the connection portion 21 on a horizontal projection plane. As another example, the drive device 14 may drive both the blowing device 12 and the intake device 13.

[0041] In this embodiment, an example has been described in which the air conditioner 11 is provided on the counterweight 2. In this example, there is no need to install the air conditioner 11 above the car 1, and a large working space can be secured above the car 1. Furthermore, by providing the air conditioner 11 on the counterweight 2, the weight of the air conditioner 11 can be used as the weight of the counterweight 2.

[0042] As another example, the air conditioner 11 may be provided in the elevator shaft 3. Furthermore, air conditioning equipment for a room in a building may be used as the air conditioner 11. In such a case, for example, air from an air-conditioned room adjacent to the elevator shaft 3 is blown out from the air outlet 22. If the landing is air-conditioned, air from the landing may also be blown out from the air outlet 22.

[0043] 8 is a diagram showing an example of hardware resources of the control device 15. The control device 15 includes, as hardware resources, a processing circuit 30 including a processor 31 and a memory 32. The processing circuit 30 may include multiple processors 31. The processing circuit 30 may include multiple memories 32.

[0044] In this embodiment, the functions of the control device 15 can be realized by software written as a program, firmware, or a combination of software and firmware. The program is stored in memory 32. The control device 15 realizes each of the above-mentioned functions by executing the program stored in memory 32 using processor 31. A semiconductor memory or the like can be used as memory 32.

[0045] Fig. 9 is a diagram showing another example of hardware resources of the control device 15. In the example shown in Fig. 9, the control device 15 includes a processing circuit 30 including a processor 31, a memory 32, and dedicated hardware 33. Fig. 9 shows an example in which some of the functions of the control device 15 are realized by the dedicated hardware 33. All of the functions of the control device 15 may also be realized by the dedicated hardware 33. The dedicated hardware 33 may be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. [Explanation of symbols]
