[0002] Patent Document 1 describes an air conditioning system for heating and cooling the inside of an elevator car. This air conditioning system includes an air conditioner installed at a location other than the elevator car. In this air conditioning system, when the car reaches a predetermined intake and exhaust position, a duct on the car side disposed in the car and a duct outside the car disposed in the hoistway from the air conditioner are connected, whereby the air of the air conditioner is blown into the car and the temperature inside the car is adjusted.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the air-conditioning system of Patent Document 1, each time the car moves to the intake and exhaust positions, the connection part of the duct outside the car expands the tip part of the duct on the car side, so that the two ducts are configured to be connected. For this reason, in the air-conditioning system of Patent Document 1, there is concern about a decrease in strength such as wear of the duct connection mechanism. In addition, the duct connection mechanism of the air-conditioning system of Patent Document 1 is sensitive to misalignment. For example, if the alignment between the elevator car and the connection part of the duct outside the car does not match due to misalignment during installation at the design and construction site, the design has to be redone and reinstalled again. Furthermore, when misalignment occurs due to an earthquake or the like, the positions of the connection part and the tip valve do not match, and there is a risk that the duct outside the car and the duct on the car side cannot be connected. In addition, due to the misalignment of the duct, the connection part and the tip valve may collide with other parts or with each other, causing the tip valve or the connection part to deform, or the car may not be able to land. In such a case, not only will the intended air-conditioning be impossible, but the elevator passengers will be trapped and the maintenance staff will have to go to the scene and rescue them manually, and it will take time to maintain and restore the air-conditioning system.

Means for Solving the Problems

[0005] One aspect of the present disclosure relates to an elevator temperature and humidity control system. The temperature and humidity control system includes a hoistway opening and closing part that opens and closes an opening formed in the side wall of the hoistway of an elevator in a building, a duct having one end connected to an exhaust port formed to face a space other than the hoistway in the building and the other end connected to the opening, and a fan that generates an air flow that sends the air in the space to the opening in the duct. The area of the exhaust port is larger than the area of the opening.

[0006] Alternatively, the elevator temperature and humidity control system includes a hoistway opening and closing part that opens and closes an opening formed in the side wall of the hoistway of the elevator in the building, an exhaust port formed toward a space other than the hoistway in the building, a duct connecting the opening and the exhaust port, a heating, ventilation, and air conditioning (HVAC) device arranged to allow conditioned air to flow into the duct from the exhaust port, and a control part that controls the opening and closing of the hoistway opening and closing part. The area of the exhaust port is configured to be larger than the area of the opening. The control part is configured to be able to acquire the operating state of the HVAC device. When the HVAC device is in operation and the elevator is in a preset specific mode, the hoistway opening and closing part is opened.

[0007] Another aspect of the present disclosure relates to an elevator temperature and humidity control device. When the elevator installed in the building is in a preset specific mode, the temperature and humidity control device opens a hoistway opening and closing part that opens and closes an opening provided on the side wall of the hoistway of the elevator, and operates a fan arranged in a duct connecting an exhaust port formed in a space other than the hoistway in the building and the opening, to generate an air flow that sends the air in the space into the opening in the duct.

[0008] Alternatively, when the operating state of an HVAC device arranged to condition a space other than the hoistway of the elevator in the building is in operation and the elevator is in a preset specific mode, the temperature and humidity control device opens a hoistway opening and closing part that opens and closes an opening provided on the side wall of the hoistway of the elevator, and operates a fan arranged in a duct connecting an exhaust port formed in the space and the opening, to generate an air flow that sends the air in the space into the opening in the duct.

[0009] Alternatively, when the operating state of an HVAC device arranged to allow conditioned air to flow into a duct connected to an opening provided on the side wall of the hoistway of the elevator in the building is in operation and the elevator is in a preset specific mode, the temperature and humidity control device opens a hoistway opening and closing part that opens and closes the opening provided on the side wall of the hoistway.

Advantages of the Invention

[0010] According to the temperature and humidity control system or device of the present disclosure, the temperature and humidity in the elevator car can be controlled without using a physical connection mechanism.

Modes for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each figure, the same or corresponding parts are denoted by the same reference numerals, and the description thereof is simplified or omitted.

[0013] Embodiment 1. FIG. 1 is a schematic diagram showing the temperature and humidity control system according to the present embodiment and its vicinity. FIG. 1 is a cross-sectional view of the elevator shaft and the vicinity of the elevator landing installed in the building as seen from the front. FIG. 2 is a schematic diagram showing the fan arranged at the exhaust port, and is a front view when the fan is viewed from the upper side of the paper surface of FIG. 1.

[0014] The temperature and humidity control system according to this embodiment includes a duct 11 installed in the building 10, a fan 12 installed in the duct 11, and an elevator shaft opening / closing part 22 formed in the elevator shaft 21 of the elevator 20.

[0015] As shown in FIG. 1, the building 10 has a plurality of floors 10A including a basement floor and above-ground floors. In FIG. 1, the basement floor of the first basement floor and the above-ground floors of the first and second above-ground floors are illustrated, but the number of floors of the building 10 is not limited. Each floor 10A is partitioned by a floor 10C and a ceiling 10D. For the sake of convenience, the space between the ceiling 10D of each floor and the floor 10C directly above it will also be referred to as the ceiling space 10E.

[0016] One end of the duct 11 is connected to an exhaust port 13 formed in the ceiling 10D of the basement floor. As shown in FIGS. 1 and 2, a fan 12 is installed in the exhaust port 13. The fan 12 sucks the air in the basement floor room from the exhaust port 13 and guides it into the duct 11. In FIG. 2, the front shape of the exhaust port 13 is shown as circular, but the shape of the exhaust port 13 and the cross-sectional shape of the duct 11 connected thereto are not limited, and for example, it may be square. Also, the shape of the fan 12 is not limited to that shown in FIG. 2. As shown in FIG. 1, an exhaust port cover 14 is arranged at the exhaust port 13.

[0017] In the example of FIG. 1, the duct 11 is formed to penetrate at least from the basement floor to the ceiling 10D of the second floor. However, the duct 11 may be installed only in the ceiling space 10E of the basement floor, for example, or when the building 10 has a plurality of floors 10A, it may be configured to penetrate some or all of the plurality of floors 10A.

[0018] The elevator 20 includes a hoistway 21 that penetrates each floor 10A of the building 10. A car 23 of the elevator 20 is disposed in the hoistway 21 so as to be movable in the vertical direction. An opening for ventilation of the air in the car 23 is formed in the car 23. A car fan may be provided in the opening. A landing 24 is provided on each floor 10A of the building 10. The landing 24 is a space adjacent to the hoistway 21. A landing door 25 is provided at the landing 24 on each floor 10A.

[0019] A plurality of openings are formed in the side wall of the hoistway 21 where the landing door 25 is formed, and a hoistway opening / closing part 22 is formed in each of the openings. The plurality of openings are formed near the ceiling 10D of each of the plurality of floors. However, there is no limitation on the installation position and the number of the hoistway opening / closing parts 22, and the temperature and humidity control system according to the present embodiment may have at least one hoistway opening / closing part 22. For example, the hoistway opening / closing part 22 may be provided on a side wall different from the side wall where the landing door 25 is provided. Further, the hoistway opening / closing part 22 may be provided on any one or more of the plurality of floors in the building 10.

[0020] The other end side of the duct 11 is connected to the uppermost hoistway opening / closing part 22. The duct 11 branches into a plurality toward the plurality of hoistway opening / closing parts 22, and a duct 11A branched from the duct 11 is connected to each of the hoistway opening / closing parts 22 other than the uppermost hoistway opening / closing part 22. However, the connection configuration between the hoistway opening / closing part 22 and the exhaust port 13 by the duct 11 is not limited to this. For example, a configuration may be adopted in which a plurality of ducts that connect one hoistway opening / closing part 22 and the exhaust port 13 without having a branch are arranged. Alternatively, a configuration may be adopted in which a plurality of ducts having a branch that connects any two or more of the plurality of hoistway opening / closing parts 22 and the exhaust port 13 are arranged.

[0021] FIG. 3 is a front view showing the hoistway opening / closing part. As shown in FIG. 3, the hoistway opening / closing part 22 includes a mechanical shutter 26 that opens and closes the opening on the side wall surface of the hoistway 21 in which the hoistway opening / closing part 22 is formed.

[0022] FIG. 4 is a diagram for explaining the operation when the hoistway opening / closing part changes from the closed state to the open state. In FIG. 4, a cross-section of the hoistway opening / closing part 22 and its vicinity is shown, with the left side indicating the closed state and the right side indicating the open state. The shutter 26 of the hoistway opening / closing part 22 opens when there is positive pressure due to the airflow from the duct 11. That is, when the fan 12 operates and an airflow A is generated in the duct 11 from the exhaust port 13 side towards the hoistway opening / closing part 22 side, and the pressure on the duct 11 side becomes higher than that on the hoistway 21 side, the shutter 26 opens. As a result, as shown in FIG. 4, the airflow A flows into the hoistway 21 from the hoistway opening / closing part 22. Also, in any of the open / closed states shown in FIG. 4, the shutter 26 is housed inside the inner wall of the hoistway 21 or inside a fessure plate with holes for ventilation, so that even if the shutter 26 fails, it does not prevent the cage 23 from moving up and down.

[0023] FIG. 5 is a schematic diagram showing a comparison of the size of the exhaust port, which is the inlet of the duct, and the opening where the hoistway opening / closing part is arranged. As shown in FIG. 5, in the temperature and humidity control system according to the present embodiment, the area of the exhaust port 13, which is the inlet of the duct 11, is formed to be larger than the cross-sectional area of the hoistway opening / closing part 22. That is, the flow path of the duct 11 connecting the exhaust port 13 and each hoistway opening / closing part 22 is wide on the exhaust port 13 side and narrow on the hoistway opening / closing part 22 side.

[0024] In the present embodiment, it is assumed that the fan 12 is constantly powered and constantly operating, for example, during the service of the elevator 20. By the operation of the fan 12, an airflow stronger than the exhaust air volume of the fan 12 can be generated in the duct 11. When a strong airflow towards the hoistway opening / closing part 22 side is generated in the duct 11, the air with stable temperature and humidity on the basement floor can be induced into the hoistway 21 with stronger force. As a result, the temperature and humidity throughout the hoistway 21 can be efficiently adjusted.

[0025] As described above, according to the temperature and humidity control system of the present embodiment, by operating the fan 12, it is possible to induce the air with stable temperature and humidity in the basement floor into the hoistway 21 with a strong air current. As a result, without using a physical connection mechanism, the temperature and humidity difference between the inside of the hoistway 21 and the landing 24 can be reduced, and the temperature and humidity difference between all the cars 23 moving up and down in the hoistway 21 and the building 10 side can be suppressed to a small level. Therefore, the temperature and humidity management load on the building manager and the elevator 20 manager can be reduced, and the load on the workers for maintenance and inspection can be reduced.

[0026] The temperature and humidity control system of the present embodiment directly blows the air on the building 10 side into the hoistway 21, and can manage the temperature and humidity in the hoistway 21 while managing the temperature and humidity of the building 10. Therefore, for example, even when the outside air temperature becomes extremely high (e.g., 40°C or higher) or extremely low (e.g., 0°C or lower), or when the humidity becomes extremely high (e.g., 100%RH), in order to operate the elevator 20 normally, the temperature and humidity in the hoistway 21 can be adjusted before the start of operation. Therefore, the building manager and the elevator manager can reduce the management load of the elevator 20 and the load on the workers for maintenance and inspection.

[0027] Also, by keeping the fan 12 operating, the temperature and humidity in the hoistway 21 can be automatically adjusted. Therefore, compared with the case of using an air conditioning device for temperature and humidity control of the car 23, the movable cable for power supply can be reduced, the environmental load can be reduced, and the power consumption of the car 23 of the elevator 20 can be significantly reduced. As a result, the temperature and humidity control system of the present embodiment can contribute to the realization of SDGs (Sustainable Development Goals) or ZEB (Net Zero Energy Building).

[0028] In this embodiment, the exhaust port 13 is provided in the ceiling 10D of the basement floor, and the case where the air in the basement floor is introduced into the duct 11 has been described. Since the temperature and humidity of the air in the basement floor are relatively stable, the temperature and humidity in the hoistway 21 can be effectively adjusted by inducing the air in the basement floor. However, the exhaust port 13, that is, the air inlet of the duct 11, is not limited to the ceiling of the basement floor and may be arranged at other locations on the basement floor or other floors 10A. However, it is desirable that the exhaust port 13 be arranged in a space where stable air with little temperature and humidity fluctuation exists so that the temperature or humidity in the hoistway 21 can be adjusted.

[0029] Embodiment 2. FIGS. 6 and 7 are diagrams showing the car duct of the temperature and humidity control system according to Embodiment 2. FIG. 6 shows a vertical cross section of the car duct, and FIG. 7 shows a perspective view of the car duct and its vicinity. The temperature and humidity control system according to Embodiment 2 has the same configuration as the temperature and humidity control system according to Embodiment 1, except that it has a car duct 30.

[0030] As shown in FIGS. 6 and 7, the car duct 30 is arranged above the ceiling of the elevator car 23. The car duct 30 is a hollow member and includes a blower section 32 surrounded by a heat insulation section 31. A car duct opening / closing section 33 is arranged at the inlet of the blower section 32. When the car 23 stops at the landing position on each floor 10A, the position of the hoistway opening / closing section 22 and the position of the car duct opening / closing section 33 of the car duct 30 are adjusted so that the car duct opening / closing section 33 and the hoistway opening / closing section 22 face each other. The outlet 34 of the blower section 32 is connected to a ventilation opening 23C formed in the ceiling of the car 23.

[0031] A plurality of shutters 35 are arranged in the car duct opening / closing part 33. The car duct opening / closing part 33 has the same mechanism as the hoistway opening / closing part 22 arranged in the hoistway 21. Due to the strong air flow from the hoistway opening / closing part 22, the shutter 35 of the car duct opening / closing part 33 opens, and the air flow A flows into the air supply part 32. A position adjusting mechanism (not shown) may be provided in the car duct opening / closing part 33 so that when the car 23 lands, the car duct opening / closing part 33 faces the hoistway opening / closing part 22. Thereby, a strong air flow can be surely made to flow into the car duct 30.

[0032] An air flow direction changing part 37 is provided at the outlet of the air supply part 32. The air flow direction changing part 37 includes a louver composed of a plurality of plate-like members. The direction of the louver may be changeable automatically or manually. The air flow A flowing into the air supply part 32 has its direction adjusted by the air flow direction changing part 37 and then flows into the car 23. Although not shown, the air in the car 23 pushed out by the air flow induced into the car 23 can be exhausted by an exhaust fan (not shown) in the car 23.

[0033] As shown in FIGS. 6 and 7, when the car 23 has landed, the hoistway opening / closing part 22 and the car duct opening / closing part 33 are opened by the strong air flow A from the duct 11. Thereby, the air flow of the air on the building 10 side can be spread into the car 23 from the air supply part 32 of the car duct 30 through the air flow direction changing part 37. Also, on the floors where the car 23 is not stopped, an air flow is sent from the hoistway opening / closing part 22 into the hoistway 21. Thereby, the temperature and humidity inside the entire hoistway 21 are similarly adjusted.

[0034] As described above, according to the present embodiment, the air blown from the basement floor through the duct 11 can cool or warm the entire inside of the hoistway 21 and the inside of the car, or adjust the humidity. Thereby, effectively, the temperature and humidity difference between the car 23 and the landing can be reduced, and the discomfort caused by the temperature and humidity difference can be reduced.

[0035] Embodiment 3. FIG. 8 is a perspective view of the cage duct of the temperature and humidity control system according to the present embodiment. The temperature and humidity control system of the present embodiment has the same configuration as the temperature and humidity control system of Embodiment 2, except that the cage duct 40 includes fins 41 in the air blowing section and a high thermal conductivity section on the inner wall of the cage.

[0036] The air blowing section of the cage duct 40 is composed of a housing including a rectangular parallelepiped section 42 having a rectangular parallelepiped shape connected to the side of the inlet cage duct opening / closing section 33 and a fan column-shaped portion 44 connected to the surface of the rectangular parallelepiped section 42 opposite to the side of the cage duct opening / closing section 33.

[0037] FIG. 9 is a perspective view showing the configuration of the rectangular parallelepiped section of the cage duct. As shown in FIG. 9, the fins 41 include a plurality of plate-like members arranged at intervals in the rectangular parallelepiped section 42 of the cage duct 40 so as to be perpendicular to the opening surface of the cage duct opening / closing section 33 and parallel to the vertical direction. Further, the upper and lower portions of the fins 41 are joined to the bottom surface 41A and the ceiling surface 41B. The bottom surface 41A and the ceiling surface 41B constitute the bottom surface and the ceiling surface of the rectangular parallelepiped section 42. Inside the rectangular parallelepiped section 42, the portion sandwiched between the plate-like members of the adjacent fins 41 serves as a passage for the air introduced into the cage duct 40. In FIG. 9, the fin shape is illustrated by a plurality of plate-like members arranged at intervals so as to be perpendicular to the opening surface and parallel to the vertical direction. However, since the purpose of the fins 41 is to transfer heat, the shape is not limited to a plate shape as long as the heat transfer rate from the passage of the air to the air sent into the air blowing section of the cage duct 40 is high, and any shape may be used.

[0038] In the present embodiment, the fins 41 of the cage duct 40 are formed of a material having a high thermal conductivity. Further, the ceiling surface 41B and the bottom surface 41A of the fins 41 are similarly formed of thick plates having a high thermal conductivity.

[0039] As shown in Fig. 8, among the side walls of the cage 23, the inner wall 23A of the side surface closer to the cage duct 40 and the surface of the inner wall 23B of the front wall (i.e., the surface facing the cage door) are high heat conductivity portions formed of a material having a high heat conductivity. A part of the inner wall 23A is connected to, for example, the bottom surface 41A of the fin 41. The connection location between the inner wall 23A and the fin 41 is not limited to the bottom surface 41A, and any connection that is thermally coupled via a plurality of high heat conductivity members is acceptable. Here, "thermally coupled" means being directly or indirectly connected in a state where the thermal resistance is extremely small. More specifically, for example, it indicates being connected in a state where the thermal resistance is smaller than a predetermined target value.

[0040] Further, a heat insulation portion 23D is disposed between the outer wall 23C that supports the cage 23 and the inner walls 23A and 23B. There is no limitation on the material of the heat insulation material that constitutes the heat insulation portion 23D.

[0041] Also, a handrail 46 is provided on the inner wall 23A of the cage 23. Here, at least a part of the surface of the handrail 46 is formed of a high heat conductivity material, similar to the inner walls 23A and 23B of the cage 23. Specifically, the portion of the handrail 46 that contacts the inner wall 23A and the portion that the user touches with their hand are formed of a high heat conductivity material. The entire surface of the handrail 46 or all of the handrail 46 may be formed of a high heat conductivity material.

[0042] In the present embodiment, there is no limitation to the material having a high thermal conductivity that constitutes the fins 41 and the inner walls 23A and 23B of the cage 23. Examples of the material include aluminum or copper. When aluminum is used, for example, about 200 μm of the surface becomes aluminum oxide, but the high thermal conductivity is maintained inside the aluminum. When it is desired to maintain the metallic luster, an antioxidant or a discoloration inhibitor may be applied to the surface. Since the thickness of the aluminum oxide and the coating thickness of the antioxidant or the like are much thinner than those of an aluminum plate or an aluminum sheet, the thermal resistance can be almost ignored. When copper is used, for example, a paint containing benzotriazole may be applied for preventing oxidation or discoloration of the surface. In this case, while suppressing oxidation and discoloration of the surface, the high thermal conductivity inside the copper can be maintained. Similar to the aluminum oxide film, since the coating thickness is much thinner than those of a copper plate or a copper sheet, the thermal resistance can be almost ignored.

[0043] Further, the plate-like member of the fins 41, the bottom surface 41A and the ceiling surface 41B, and the fins 41 and the inner wall 23A, and the inner wall 23A and the handrail 46 are thermally bonded using the same material. Here, an adhesive having a low thermal conductivity is not used. Further, for example, when an oxide film or a coating film is formed on a material having a high thermal conductivity, as a pretreatment, the oxide film at the joint portion is removed or the coating film is not formed by a mask, and then thermal bonding is performed.

[0044] FIG. 10 is a longitudinal sectional view of the inner wall of the front wall of the cage. As shown in FIG. 10, the surface of the inner wall 23B of the front wall of the cage 23 has a shape with unevenness whose longitudinal section is wavy.

[0045] FIG. 11 is a sectional view for explaining the air flow, heat transfer, and heat conduction flow in the temperature and humidity control system according to the present embodiment. FIG. 11 shows a longitudinal section perpendicular to the boarding door 25 of the cage 23 and the cage duct 40. Also in FIG. 11, the air flow for heat transfer from the duct 11 is mainly indicated by an arrow A, and the flow for conducting the heat transferred from the air flow, that is, the heat conduction flow, is mainly indicated by an arrow B.

[0046] As shown in FIG. 11, the airflow A from the duct 11 flows into the cage duct 40, passes through the fins 41, and is guided from the outlet into the interior of the cage 23. At this time, the heat of the airflow is transferred to the fins 41 by heat conduction, and the heat of the fins 41 is immediately transmitted to the inner walls 23A and 23B and the handrail 46 in contact with the inner wall 23A by heat conduction. In particular, the inner wall 23B near the outlet of the duct 40 is also effectively temperature-controlled by the airflow flowing from the duct 40 into the cage 23. In addition, the surface of the inner wall 23B is formed with irregularities. Therefore, the temperature transferred by heat conduction by the airflow flowing into the inner wall 23B can be effectively transmitted throughout the interior of the cage 23. Thereby, the interior of the cage 23 can be brought closer to the temperature on the building 10 side. Further, for example, a user who rides in the cage 23 can immediately feel, through the fins heat-transferred by the inflowing airflow and heat-conducted from the fins, the temperature close to the building 10 side by directly grasping the handrail 46 with the hand C. Thereby, the discomfort caused by the temperature difference between the building 10 side and the interior of the cage 23 is reduced more quickly. Also, the user can feel a temperature close to the temperature on the building side by approaching and touching the temperature-controlled inner wall 23A or 23B. Thereby, the discomfort caused by the temperature difference between the building side and the interior of the cage is reduced more quickly.

[0047] In addition, in the present embodiment, the temperature and humidity control system having the fins 41 in the cage duct 40, the inner wall 23A connected thereto, the front inner wall 23B, and the handrail 46 has been described. However, the temperature and humidity control system is not limited to those having all of these, and may have any one or more of the inner walls 23A, 23B, and the handrail 46. Even in this case, the air temperature in the building can be transmitted to the cage 23 with a certain degree of efficiency.

[0048] In addition, in this embodiment, the case where only the inner wall 23A of the side wall close to the cage duct 40 and the inner wall 23B of the front wall are made of a material with high thermal conductivity has been described. However, the inner walls of the other side walls of the cage 23 may also be formed of a material with high thermal conductivity. Also, instead of the entire inner wall surface, only a part may be formed of a material with high thermal conductivity. When the inner walls other than the inner walls 23A and 23B are also formed of a material with high thermal conductivity, a heat insulating portion is also formed between the inner wall and the outer wall.

[0049] In addition, in this embodiment, the case where only the inner wall 23B of the front wall has a cross-sectional uneven shape has been described. However, the inner wall 23A may be formed in an uneven shape, or the inner walls of the other side walls may be formed of a material with high thermal conductivity and have an uneven shape similar to that of the inner wall 23B.

[0050] Embodiment 4. FIG. 12 is a schematic cross-sectional view showing the temperature and humidity control system according to Embodiment 4 and its surroundings. FIG. 12 represents a longitudinal cross-section of the building 10 as seen from the front of the landing of the elevator 20. The temperature and humidity control system of Embodiment 4 has the same configuration as the temperature and humidity control system of Embodiment 1 except that it has a control unit 50.

[0051] The control unit 50 also has a function as a control panel for controlling the operation of the elevator 20 and also functions as a temperature and humidity control device. The control unit 50 can control the operation of the fan 12. Also, although not shown, the temperature and humidity control device may be separated, and in that case, it communicates with and controls the control unit. The setting of the reference value for the temperature and humidity control device described below is for temperature and humidity. The application of the reference value may be for both temperature and humidity or either one of them. Hereinafter, the "first reference value" is the reference value for temperature, and the "second reference value" is the reference value for humidity. Also, when referring to "temperature and humidity", it means either one or both of temperature and humidity, and when referring to "reference value", it means either one or both of the first reference value and the second reference value.

[0052] FIG. 13 is a flowchart showing the control operation of the temperature and humidity control executed by the control unit 50. The temperature and humidity control will be described with reference to FIG. 13. The flowchart of FIG. 13 is repeatedly executed at a certain control interval, for example, during the service of the elevator 20.

[0053] As shown in FIG. 13, first, in step S400, it is determined whether the difference between the temperature and humidity on the building 10 side and the temperature and humidity in the car 23 is greater than the reference value. Here, when the reference value is set for both temperature and humidity, the temperature difference is compared with the first reference value, and the humidity difference is compared with the second reference value. When only the temperature is set as the target, the temperature difference is compared with the first reference value. When only the humidity is set as the target, the humidity difference is compared with the second reference value. When both temperature and humidity are compared, for example, it is determined that the temperature and humidity difference is greater than the reference value when at least one of the cases where the temperature difference is greater than the first reference value and the humidity difference is greater than the second reference value is satisfied. However, a configuration may be adopted in which it is determined that the temperature and humidity difference is greater than the reference value when the temperature difference is greater than the first reference value and the humidity difference is greater than the second reference value.

[0054] The temperature and humidity on the side of the building 10 are detected by, for example, a thermometer or a temperature and humidity sensor installed near the exhaust port 13 of the duct 11 of the building 10. Also, the temperature and humidity inside the basket are detected by a thermometer or a temperature and humidity sensor installed in the basket 23. However, the installation position of the means for detecting the temperature and humidity is not limited to this. The reference value is an appropriately set temperature and humidity difference. Also, although not shown in the figures and flowcharts, it may be configured such that the reference value can be changed from the mobile interface according to the situation. The temperature and humidity difference set as the reference value may be set, for example, according to the boundary value at which people feel uncomfortable. The mobile interface refers to the general term for these hardware such as temperature and humidity adjustment buttons and switches, or software with an interface that can be set by wearable devices such as PCs (Personal Computers), tablets, smartphones, cellular phones, smart watches, eyewear devices such as smart contact lenses and AR glasses (Argmented Reality glasses). Also, the mobile interface may be installed as a part of the control unit or the temperature and humidity adjustment device. For example, a maintenance worker or the like sets the boundary value at which they feel uncomfortable at the site as the reference value from the mobile interface and transmits the new reference value to be set to the temperature and humidity adjustment device, so that an optimal reference value can be set for each site.

[0055] In step S400, if it is determined that the temperature and humidity difference is less than or equal to the reference value, then temperature and humidity adjustment is not required, and thus the current process ends. On the other hand, if it is determined in step S400 that the temperature and humidity difference is greater than the reference value, the process proceeds to step S402.

[0056] In step S402, the fan 12 is operated. The control unit 50 transmits a predetermined control signal to the fan 12 to operate the fan 12.

[0057] As described above, according to the present embodiment, the temperature and humidity in the hoistway 21 are controlled by the control of the control unit 50, and the temperature and humidity difference between the building 10 side and the inside of the car 23 can be effectively suppressed.

[0058] In the present embodiment, the case where the control by the control unit 50 is applied to the temperature and humidity adjustment system of the first embodiment has been described. However, the present invention is not limited to this, and the control of the temperature and humidity adjustment by the control unit 50 can also be applied to the temperature and humidity adjustment systems of the second or third embodiments.

[0059] Embodiment 5. FIG. 14 is a schematic cross-sectional view showing the temperature and humidity adjustment system according to the fourth embodiment and its surroundings. The temperature and humidity adjustment system of the fifth embodiment includes an electronically controlled hoistway opening / closing unit 51 instead of the hoistway opening / closing unit 22, and has the same configuration as the temperature and humidity adjustment system of the fourth embodiment except that the control unit 50 controls the opening and closing of the hoistway opening / closing unit 51.

[0060] Figure 15 schematically shows the operation of the hoistway opening / closing part in this embodiment. In Figure 15, the operation when the upper hoistway opening / closing part 51 changes from the closed state to the opened state at the lower side is shown. Also, the front view of the hoistway opening / closing part 51 is shown on the left side respectively, and the longitudinal section of the hoistway opening / closing part 51 is shown on the right side thereof. Note that in Figure 15, the hoistway opening / closing part 51 with a rectangular front shape is shown, but the shape of the hoistway opening / closing part 51 is not limited thereto, and it may be circular or the like, for example. Also, in Figure 15, as the shutter 52, a configuration is shown in which the shutter 52 slides upward to form an open state for sending air flow, but the opening / closing mechanism of the shutter 52 is not limited to this. The opening / closing mechanism of the shutter 52 may open in any direction of up, down, left, or right within a range that does not interfere with the elevator car hoisting as long as it can be in an open state for sending air flow. Alternatively, the shutter 52 may be configured to be rolled up or folded to form an open state. However, in case the shutter fails, it is desirable to store the shutter 52 inside the hoistway wall or inside the fascia plate so as not to interfere with the operation of the car 23 in the hoistway 21.

[0061] As shown in Figure 15, the hoistway opening / closing part 51 provided on the wall surface of the hoistway 21 includes a shutter 52. The opening / closing operation of the shutter 52 is controlled by the control unit 50. As shown in Figure 14, when the shutter 52 slides upward according to a signal from the control unit 50, the hoistway opening / closing part 51 is opened. As a result, the air from the duct 11 can be induced to the hoistway 21 side.

[0062] The control unit 50 controls the operation of the hoistway opening / closing part 51 and has a function as an elevator control panel for controlling the operation of the elevator car. The control unit 50 is connected to be able to transmit and receive signals with the car 23 via the car communication cable 53. The control unit 50 functions as a temperature and humidity adjustment device and performs temperature and humidity adjustment control to adjust the temperature and humidity inside the car 23 when the temperature difference between the temperature and humidity inside the car 23 and the building 10 side becomes larger than the first reference value or the humidity difference becomes larger than the second reference value, and the elevator 20 is in a predetermined mode.

[0063] FIG. 16 is a flowchart for explaining the control operation of the temperature and humidity control executed by the control unit 50. The temperature and humidity control in the present embodiment will be described with reference to FIG. 16. The control operation in FIG. 16 is repeatedly executed at a certain control interval, for example, during the service of the elevator.

[0064] Specifically, as shown in FIG. 16, first in step S500, it is determined whether the difference between the temperature and humidity on the building side and the temperature and humidity in the car is greater than the reference value. Here, when the reference value is set for both temperature and humidity, the temperature difference is compared with the first reference value, and the humidity difference is compared with the second reference value. When only the temperature is set as the target, the temperature difference is compared with the first reference value. When only the humidity is set as the target, the humidity difference is compared with the second reference value. When both temperature and humidity are compared, for example, when at least one of the cases where the temperature difference is greater than the first reference value and the humidity difference is greater than the second reference value is satisfied, it is determined that the temperature and humidity difference is greater than the reference value. However, a configuration may also be adopted in which it is determined that the temperature and humidity difference is greater than the reference value when the temperature difference is greater than the first reference value and the humidity difference is greater than the second reference value.

[0065] The temperature and humidity on the building 10 side are detected by, for example, a thermometer or a temperature and humidity sensor installed near the exhaust port 13 of the duct 11 of the building 10. The temperature and humidity in the car are detected by a thermometer or a temperature and humidity sensor installed in the car 23. However, the installation position of the means for detecting the temperature and humidity is not limited to this. The reference value is a temperature and humidity difference set in advance as appropriate. Also, although not shown in the figures and flowcharts, a configuration may be adopted in which the reference value can be changed from the above-described mobile interface according to the situation. The temperature and humidity difference set as the reference value may be set, for example, according to the boundary value at which a person feels uncomfortable.

[0066] If it is determined in step S500 that the temperature-humidity difference is less than or equal to the reference value, since temperature-humidity adjustment is not required, the current process ends. On the other hand, if it is determined in step S500 that the temperature-humidity difference is greater than the reference value, the process proceeds to step S502.

[0067] In step S502, it is determined whether the elevator 20 is in a predetermined mode. Here, the predetermined mode is a specific mode indicating that the car 23 is in a state where it can adjust the temperature and humidity, and specific conditions can be appropriately set in advance. Specifically, for example, the predetermined mode is that the car 23 has become standby at any floor.

[0068] In step S502, if it is determined that the elevator 20 is not in the predetermined mode, the current process ends. On the other hand, in step S502, if it is determined that the elevator 20 is in the predetermined mode, then the process proceeds to step S504.

[0069] In step S504, the operation of the fan 12 is started and the hoistway opening / closing part 51 is opened. Although the temperature-humidity adjustment system is provided with the hoistway opening / closing part 51 on each floor 10A, here, only the hoistway opening / closing part 51 corresponding to the floor 10A where the car 23 in the predetermined mode is stopped is opened. Thereby, the air flow from the duct 11 flows strongly only into the hoistway opening / closing part 51 near the floor 10A where the standby car 23 has landed. Therefore, the air on the building 10 side can be effectively sent into the landed car 23. Thereby, the air in the car 23 is efficiently ventilated by the air flow from the duct 11, and the temperature and humidity in the car 23 are adjusted.

[0070] Next, it is determined whether there is a call for the car 23. The call for the car 23 is input by an operation panel or the like that performs call registration installed at the landing 24 and is transmitted to the control unit 50 which is the control panel of the elevator 20.

[0071] In step S506, if it is determined that there is no call, the process returns to step S506. Until it is determined in step S506 that there is a call, the hoistway opening / closing unit 51 remains in the open state, and the determination process of step S506 is repeated at regular intervals. On the other hand, if it is determined in step S506 that there is a call, the process proceeds to step S508.

[0072] In step S508, a release command for a predetermined mode is issued. In step S510, upon receiving the release command, the operation of the fan 12 is stopped, and the hoistway opening / closing unit 51 opened in step S504 returns to the closed state.

[0073] In step S512, it is determined that the release of the predetermined mode is completed. Next, in step S514, the car 23 returns to the normal mode. As a result, the car 23 can operate normally and is in a state where it can respond to the registered calls. Thereafter, the current process ends.

[0074] As described above, in the present embodiment, when the car 23 is in a predetermined mode in which the temperature and humidity can be adjusted, only the hoistway opening / closing unit 51 corresponding to the standby position of the car 23 is opened. As a result, the air flow from the building 10 side from the duct 11 can be introduced into the car 23 with great force. Thereby, the temperature and humidity in the car 23 can be effectively adjusted.

[0075] Also, in the present embodiment, the fan 12 operates and the temperature and humidity are adjusted only when the temperature and humidity difference between the building 10 side and the car 23 side is large and the car 23 is in the predetermined mode. Since it is not necessary to operate the fan 12 constantly, the amount of electricity for the time when the fan 12 is not operated can be reduced. However, the execution conditions of the temperature and humidity control are not limited to this. For example, when the car 23 is in the predetermined mode, the hoistway opening / closing unit 51 may be controlled to open regardless of the temperature and humidity difference between the building 10 side and the car 23 side.

[0076] In addition, in the present embodiment, an electric elevator shaft opening / closing unit 51 that opens and closes according to a command from the control unit 50 is installed for temperature and humidity control. Generally, the electric elevator shaft opening / closing unit 51 has higher airtightness than the mechanical elevator shaft opening / closing unit 22. Therefore, leakage of the air flow in the duct 11 can be suppressed, and the air on the building 10 side can be sent with a stronger force only to the opened elevator shaft opening / closing unit 51.

[0077] In the present embodiment, the case where the temperature and humidity control by the control unit 50 is applied to the temperature and humidity control system having the configuration described in the first embodiment has been described. However, the present disclosure is not limited to this. For example, the temperature and humidity control by the control unit 50 can be applied to the temperature and humidity control system having the basket duct shown in the second or third embodiment. In this case, an electric opening / closing mechanism similar to the elevator shaft opening / closing unit 51 may be applied to the basket duct opening / closing unit described in the second or third embodiment, and the control unit 50 may control the opening and closing of the basket duct opening / closing unit so as to open and close at the same timing as the elevator shaft opening / closing unit 51. By applying the temperature and humidity control according to the present embodiment to the temperature and humidity control system of the second or third embodiment, the temperature and humidity in the basket 23 can be adjusted more effectively.

[0078] Embodiment 6. FIG. 17 is a schematic cross-sectional view showing a temperature and humidity control system according to Embodiment 6 and its surroundings. FIG. 17 represents a longitudinal section of the building 10 as viewed from the front of the landing of the elevator 20. The temperature and humidity control system of FIG. 15 has the same configuration as the temperature and humidity control system of Embodiment 5 except that an air conditioning device 54 is provided in the building 10.

[0079] The air conditioner 54 cools, heats, and controls the humidity of the air in the basement floor indoor space, and is installed on the ceiling 10D of the basement floor. That is, in the present embodiment, the exhaust port 13 of the duct 11 is installed on the ceiling 10D of the basement floor, and the air conditioner 54 is installed in the vicinity of the exhaust port 13. However, the installation position of the air conditioner 54 in the temperature and humidity control system is not limited to the ceiling 10D of the basement floor, and it may be installed at other positions as long as it can cool and heat the air in the vicinity of the exhaust port 13 of the duct 11.

[0080] In the present embodiment, the control unit 50 performs temperature and humidity control to adjust the temperature and humidity inside the car 23 when the temperature and humidity difference between the inside of the car and the building 10 side becomes larger than the reference value and the car 23 is in a predetermined mode, in the same manner as in Embodiment 5. However, in the present embodiment, it is different from the control of the temperature and humidity control system of Embodiment 5 in that the temperature and humidity inside the car 23 are adjusted when the air conditioner 54 is operating and the car 23 is in a predetermined mode.

[0081] FIG. 18 is a diagram showing the control conditions in the temperature and humidity control of the temperature and humidity control system according to the present embodiment. In the column of "predetermined mode" in FIG. 18, when the elevator 20 is in the predetermined mode, it is indicated as "ON", and when it is not in the predetermined mode, it is indicated as "OFF". In the column of "air conditioner", it is shown whether the air conditioner 54 is "operating" or "stopped". In the column of "state of the hoistway opening / closing part", it is shown whether the hoistway opening / closing part 51 corresponding to the floor where the car 23 has landed is in the "open" state or the "closed" state.

[0082] As shown in states 2, 3, and 4 in FIG. 18, when at least one of the case where the predetermined mode of the elevator 20 is OFF and the case where the air conditioner 54 is stopped is satisfied, the hoistway opening / closing part 51 corresponding to the floor 10A where the car 23 has landed is not opened and is in the closed state. On the other hand, as shown in state 1, when the predetermined mode is ON and the air conditioner 54 is operating, the hoistway opening / closing part 51 corresponding to the floor where the car 23 has landed is opened.

[0083] FIG. 19 is a flowchart showing the control operation of the temperature and humidity control executed by the control unit 50. The temperature and humidity control of the present embodiment will be described with reference to FIG. 19. The flowchart of FIG. 19 is the same as the flowchart of FIG. 16 except that the process of step S600 is included before step S500. Therefore, the description of the processes overlapping with the flowchart of FIG. 16 will be omitted.

[0084] In the temperature and humidity control shown in FIG. 19, first, at step S600, it is determined whether the air conditioner 54 is operating. If it is determined at step S600 that the air conditioner 54 is stopped, the current process ends. On the other hand, if it is determined at step S600 that the air conditioner 54 is operating, the process proceeds to step S500. Thereafter, as described in Embodiment 5, the processes of steps S500 to S514 are appropriately performed.

[0085] As described above, the temperature and humidity control system according to the present embodiment performs temperature and humidity control of the cage 23 when the air conditioner 54 in the basement floor where the exhaust port 13 is formed is operating. Thereby, air with stable temperature and humidity can be blown into the hoistway 21 by air conditioning, and stable temperature and humidity control of the cage 23 can be performed.

[0086] Note that, similar to the case of Embodiment 5, the temperature and humidity control of the present embodiment is not limited to the temperature and humidity control system having the configuration described in Embodiment 1, and may be applied to the temperature and humidity control system having the cage duct shown in Embodiment 2 or 3. Also in this case, the air conditioner may be arranged so as to air-condition the air in the space where the exhaust port 13 of the duct 11 is formed. By applying the temperature and humidity control of the present embodiment to the temperature and humidity control systems of Embodiments 2 and 3 having the cage ducts 30 and 40, more effective temperature and humidity control inside the cage 23 can be performed. In addition, by using the exhaust air, the temperature and humidity difference inside the elevator cage 23 can be reduced, eliminating the need to install an air conditioner on the elevator side, where only the temperature and humidity inside the building were controlled by the building's air conditioner.

[0087] Embodiment 7 FIG. 20 is a cross-sectional view for explaining the temperature and humidity control system of Embodiment 7. The temperature and humidity control system of this embodiment has an exhaust port of a duct 55 of a temperature and humidity control device installed at either an indoor or outdoor location of a building 10, and a heating, ventilation, and air conditioning (HVAC) device 56 is installed facing the exhaust port, instead of a fan 12. Except for this point, it has the same configuration as the temperature and humidity control system of Embodiment 6.

[0088] As shown in FIG. 20, an exhaust port 57 of the duct 55 is provided so as to face the air outlet of the air conditioned by the HVAC device 56. There is no limitation on the installation position of the HVAC device 56, that is, the position of the exhaust port 57 of the duct 55, and it may be installed at any location inside or outside the building 10. A fan 58 is built into the HVAC device 56. The air conditioned by the HVAC device 56 is configured to flow directly into the duct 55 by the fan 58. There is no need to newly provide a fan separately from the HVAC device 56 of the building 10. Note that, as in the case of Embodiment 1, the duct 55 is configured such that its flow path cross-section is large on the exhaust port 57 side and small on the elevator shaft opening / closing part 51 side.

[0089] The temperature and humidity control system of this embodiment performs temperature and humidity control in the same manner as in Embodiment 6. Thereby, the air conditioned by the HVAC device 56 can be directly induced into the cage 23. Therefore, the temperature and humidity of the cage 23 can be effectively controlled.

[0090] In this embodiment, the case where the duct 55 and the HVAC device 56 are installed in place of the duct 11 and the fan 12 having the configuration of Embodiment 1 has been described. However, the configurations of the duct 55 and the HVAC device 56 may be applied in place of the duct 11 and the fan 12 of the temperature and humidity control system of Embodiment 2 or 3.

[0091] Although the preferred embodiments and the like have been described in detail above, the present invention is not limited to the above-described embodiments and the like, and various modifications and substitutions can be made to the above-described embodiments and the like without departing from the scope described in the claims.
