In the control cabinet, the housing includes a right side air inlet and a left side air inlet having an area in the machine chamber through which an amount of air capable of cooling the interior of the housing can be introduced, and a back air inlet having an area in the lifting path through which an amount of air capable of cooling the interior of the housing can be introduced.

Description

Technical Field

[0001] This invention relates to an elevator control cabinet, and more particularly to an elevator control cabinet that uses air introduced from an air inlet to cool its interior. Background Technology

[0002] Previously, an elevator control cabinet was known to utilize air introduced from an air inlet for internal cooling. Such an elevator control cabinet is disclosed, for example, in International Publication No. 2017 / 141311.

[0003] International Publication No. 2017 / 141311 discloses a control cabinet for managing the drive motor and various devices constituting the elevator system. The control cabinet in International Publication No. 2017 / 141311 draws in external air through an air inlet and exhausts air through an exhaust outlet, thereby forming a cooling flow path for cooling the forced air cooling equipment and the natural cooling equipment (control equipment). Furthermore, the control cabinet in International Publication No. 2017 / 141311 is located inside the elevator system's lifting path or inside a machine room separate from the lifting path. Summary of the Invention

[0004] However, the control cabinet described in International Publication No. 2017 / 141311 sometimes requires different positions and installation methods for the air inlet and outlet depending on whether it is located inside the lifting path or inside the machine room. In other words, the control cabinet described in International Publication No. 2017 / 141311 involves time and effort required to design the housing structure individually for each installation environment. This time and effort spent designing the required housing structure for each installation environment reduces productivity. Therefore, a control cabinet (elevator control cabinet) that can reduce the time and effort required to design the required housing structure for each installation environment is desired.

[0005] The present invention was made to solve the problems described above, and one object of the present invention is to provide an elevator control cabinet that can reduce the effort and time required to construct the housing for each setting environment.

[0006] Solution for solving the problem

[0007] To achieve the above objectives, an elevator control cabinet of one aspect of the present invention is at least disposed in a first installation environment and a second installation environment. A control device for controlling the operation of an elevator is disposed inside the elevator control cabinet. The elevator control cabinet has a housing, and the control device is disposed inside the housing. The housing includes: a first air inlet having an area in the first installation environment capable of introducing an amount of air capable of cooling the interior of the housing; and a second air inlet having an area in the second installation environment capable of introducing an amount of air capable of cooling the interior of the housing.

[0008] In one aspect of the elevator control cabinet, as described above, the housing includes: a first air inlet having an area capable of introducing an amount of air that can cool the interior of the housing in a first installation environment; and a second air inlet having an area capable of introducing an amount of air that can cool the interior of the housing in a second installation environment. Thus, it is not necessary to change (design separately) the location of the air inlets for at least two different installation environments (the first and second installation environments). As a result, the effort and time required to construct the housing for each installation environment can be reduced.

[0009] In the elevator control cabinet described above, it is preferable that the housing further includes a ventilation path through which air introduced from at least one of the first and second air inlets flows, wherein the area of ​​the first and second air inlets is greater than or equal to the area of ​​the cross-section of the ventilation path. With this configuration, the first and second air inlets can have relatively large areas, thus allowing for easy introduction of an amount of air sufficient to adequately cool the control equipment regardless of the installation environment.

[0010] In the elevator control cabinet described above, it is preferable that the housing has a rectangular parallelepiped shape that extends vertically, and that the first and second air inlets are located on different sides, front, and back of the housing that extend vertically. This configuration reduces the effort and time required to design the components that constitute the relatively large areas of the sides, front, and back of the housing. Furthermore, it reduces the variety of components that make up the housing, thus improving productivity.

[0011] In the elevator control cabinet described above, it is preferable that the housing includes a first exhaust port disposed on the top surface of the housing and discharging air to the outside of the housing, and includes a wind tunnel portion that is configured to cover the first exhaust port to change the direction of airflow discharged from the first exhaust port. With this configuration, compared to the case without a wind tunnel portion, the direction of airflow discharged from the exhaust port can be easily changed for each installation environment. As a result, it is not necessary to design exhaust ports separately for each installation environment, thus easily reducing the effort and time required to design exhaust ports in the construction of the housing for each installation environment.

[0012] In this case, it is preferable that, regarding the wind tunnel section, second exhaust ports are provided on the back and sides of the wind tunnel section for discharging the air discharged from the first exhaust port, and no second exhaust port is provided on the top surface of the wind tunnel section. If configured in this way, since no exhaust port is provided on the top surface of the elevator control cabinet, it is possible to prevent water droplets formed by condensation or other factors falling from above and dust from entering the interior and damaging the control equipment.

[0013] In the elevator control cabinet described above, preferably, the housing includes a first exhaust port disposed on the top surface of the housing and discharging air to the outside of the housing, the control device includes a frequency converter unit, the frequency converter unit has a cooling fan located above it in the vertical direction, and a first air intake and a second air intake are disposed below the frequency converter unit in the vertical direction. With this configuration, regardless of the installation environment, the frequency converter unit, which has a higher cooling priority, can be directly cooled using air introduced from at least one of the first and second air intakes.

[0014] In this case, it is preferable that the control device also includes a battery, which is vertically positioned below the first and second air intakes. With this configuration, air heated by the battery rises to the positions of the first and second air intakes, is cooled by contact with air introduced from at least one of the first and second air intakes, and then descends to the battery. As a result, not only is the control device (inverter unit) positioned above the first and second air intakes cooled, but the control device positioned below the first and second air intakes is also cooled due to convection between the battery and the air between them. Therefore, damage to the inverter unit from corrosive gases that may be released from the battery can be prevented, and the entire control device can be cooled using air introduced from at least one of the first and second air intakes.

[0015] In elevator control cabinets where the housing includes a ventilation path through which air introduced from at least one of the first and second air intakes flows, and the area of ​​the first and second air intakes is equal to or greater than the area of ​​the cross-section of the ventilation path, it is preferable that the control equipment includes an inverter unit with cooling fins, and the area of ​​the cross-section of the ventilation path is equal to the ventilation area of ​​the cooling fins. With this configuration, compared to cases where the area of ​​the first and second air intakes is smaller than the ventilation area of ​​the cooling fins, the amount of air passing through the cooling fins increases. As a result, regardless of the installation environment, the inverter unit, which has a higher cooling priority, can be efficiently cooled using air introduced from at least one of the first and second air intakes.

[0016] In the elevator control cabinet described above, it is preferable that the first installation environment is either within the elevator's lifting path or in a machine room separately from the elevator's lifting path, and the second installation environment is either within the elevator's lifting path or in a machine room separately from the elevator's lifting path. With this configuration, the time and effort required to construct the housing for the elevator's lifting path (where the control cabinet is most likely to be installed) and the machine room separately from the elevator's lifting path can be reduced. As a result, the time and effort required to construct the housing for each installation environment can be effectively reduced. Attached Figure Description

[0026] The embodiments embodied in the present invention will now be described with reference to the accompanying drawings.

[0027] (Elevator structure)

[0028] Reference Figure 1 The overall structure of the elevator 200 in this embodiment will be explained.

[0029] like Figure 1 As shown, elevator 200 is a device installed in a building or the like for moving a car 211 vertically while carrying people or goods. Elevator 200 includes a car 211 and a counterweight 212 installed in a lifting path 220, a lifting system 210 installed across the lifting path 220 and a machine room 230, and a control cabinet 100 installed in the lifting path 220 or the machine room 230. However, due to limitations of the building in which elevator 200 is installed, sometimes a machine room 230 is not provided. In this case, the car 211, counterweight 212, lifting system 210, and control cabinet 100 are all installed within the lifting path 220. Furthermore, the control cabinet 100 is an example of the "control cabinet for elevators" as claimed in the claims.

[0030] The lifting system 210 is a system that uses counterweights 212, etc., to move the car 211 vertically. The lifting path 220 is the space for the car 211 to move up and down, separated by a door to prevent personnel from entering except during maintenance. The machine room 230 is located adjacent to the vertical direction above the lifting path 220, and a portion of the lifting system 210 and the control cabinet 100 are disposed inside the machine room 230. Control equipment for controlling the lifting system 210 is disposed inside the control cabinet 100; in the case of a machine room 230, the control cabinet 100 is located within the machine room 230 (e.g., Figure 1 (the position of the solid line), in the absence of a machine room 230, the control cabinet 100 is located within the lifting path 220 (e.g., the position of the solid line), Figure 1 (The position of the dotted line). In addition, the lifting path 220 and the machine room 230 are examples of one and the other of the "first setting environment" and "second setting environment" in the claims.

[0031] (Structure of the control cabinet when it is located in a machine room)

[0032] Next, refer to Figures 2-5 The structure of the control cabinet 100, which is installed in the machine room 230 according to this embodiment, will be explained.

[0033] like Figure 2 and Figure 3 As shown, the control cabinet 100 includes a front component 10, a right side component 20, a left side component 30, a rear component 40, a top component 50, a first bottom component 60, and a control device 90 (see reference). Figure 5 Furthermore, when viewing the control cabinet 100 from the front, the left-right direction (one direction in the horizontal plane) is designated as the X direction. The up-down direction (vertical direction) of the control cabinet 100 is designated as the Z direction. The direction of the control cabinet 100 orthogonal to the X and Z directions (other directions in the horizontal plane) is designated as the Y direction. Hereinafter, one side of the X direction will be designated as the X1 direction, and the other side as the X2 direction. In the Y direction, when viewing the control cabinet 100 from the front, the inner side will be designated as the Y1 direction, and the near-front side as the Y2 direction. In the Z direction, the upward direction will be designated as the Z1 direction, and the downward direction as the Z2 direction. In this embodiment, the control cabinet 100 has a cuboid shape that is longer in the vertical direction (Z direction). Furthermore, the front member 10, right side member 20, left side member 30, back member 40, top member 50, and first bottom member 60 are examples of the "shell" as claimed in the claims.

[0034] like Figure 2 , Figure 3 and Figure 5As shown, the front member 10 is disposed on the front side (Y2 side) of the control cabinet 100 and is formed of a flat metal plate. The front member 10 includes an upper front member 10a and a lower front member 10b. The upper front member 10a is disposed above the front side of the control cabinet 100 in the vertical direction (Z1 side). The lower front member 10b is separate from the upper front member 10a and is disposed below the front side of the control cabinet 100 in the vertical direction (Z2 side). The upper front member 10a is configured to be connected to the inverter unit 91 (see reference 90) in the control device 90 described later. Figure 5 Corresponding to the space, the lower front component 10b is configured to be connected to the equipment in the control device 90 other than the inverter unit 91 (see reference). Figure 5 The spatial correspondence is as follows: that is, when the upper front component 10a is removed, the inverter unit 91 is exposed, and when the lower front component 10b is removed, the equipment in the control device 90 other than the inverter unit 91 is exposed.

[0035] The right-side component 20 includes a right-side air inlet 20i and is provided with a right-side wiring hole cover 20g and a right-side wiring hole cover 21g. The right-side component 20, when viewed from the front of the control cabinet 100, is located on the right side (X1 side) and is formed of a metal plate. The right-side air inlet 20i is used to introduce air into the interior of the control cabinet 100 for use with control devices 90 (see reference 90) disposed inside the control cabinet 100. Figure 5 The air inlet (opening) is for cooling the interior of the control cabinet 100, including the control cabinet itself. The right-side air inlet 20i includes multiple openings arranged in a matrix. The right-side wiring hole cover 20g and right-side wiring hole cover 21g are covers that cover the openings of the right-side member 20 to allow wiring to pass through. The right-side wiring hole cover 20g is larger than the right-side wiring hole cover 21g. The right-side wiring hole cover 20g and right-side wiring hole cover 21g are, for example, grommets.

[0036] The right-side air inlet 20i, right-side wiring hole cover 20g, and right-side wiring hole cover 21g are arranged in this order from top to bottom in the vertical direction (Z direction) on the right-side member 20. The right-side air inlet 20i, right-side wiring hole cover 20g, and right-side wiring hole cover 21g are located near the center of the right-side member 20 in the vertical direction (Z direction). Furthermore, "near the center of the right-side member 20" is a broad concept that includes not only the center of the right-side member 20 itself but also its periphery. The right-side air inlet 20i, right-side wiring hole cover 20g, and right-side wiring hole cover 21g are located near the rear side (Y1 side) of the right-side member 20 in the depth direction (Y direction) of the control cabinet 100.

[0037] The left side component 30 includes a left side air inlet 30i and is provided with a left side wiring hole cover 30g. The left side component 30, when viewed from the front of the control cabinet 100, is located on the left side (X2 side) and is formed of a metal plate. The left side air inlet 30i is used to introduce air into the interior of the control cabinet 100 for control devices 90 (see reference 90) disposed inside the control cabinet 100. Figure 5 The air inlet (opening) is for cooling the interior of the control cabinet 100, including the control cabinet itself. The left side air inlet 30i includes multiple openings arranged in a matrix. The left side air inlet 30i has the same shape as the right side air inlet 20i and is located in the same position in the vertical direction (Z direction). The left side wiring hole cover 30g is a cover that covers the openings of the left side member 30 for wiring to pass through. The left side wiring hole cover 30g is, for example, a cable ring.

[0038] The left-side air inlet 30i and the left-side wiring hole cover 30g are arranged in this order from top to bottom on the left-side member 30 in the vertical direction (Z direction). The left-side air inlet 30i and the left-side wiring hole cover 30g are located near the center of the left-side member 30 in the vertical direction (Z direction). Furthermore, "near the center of the left-side member 30" is a broad concept that includes not only the center of the left-side member 30 itself but also the periphery of the center of the left-side member 30. The left-side air inlet 30i and the left-side wiring hole cover 30g are located near the rear side (Y1 side) of the left-side member 30 in the depth direction (Y direction) of the control cabinet 100.

[0039] The rear panel 40 includes a rear air inlet 40i, a rear ventilation inlet 41i, a first mounting portion 40n, a second mounting portion 41n, and a third mounting portion 42n, and is provided with a rear wiring hole cover 40g, a rear wiring hole cover 41g, and a rear wiring hole cover 42g. The rear panel 40 is located on the rear side (Y1 side) of the control cabinet 100 and is formed of a metal plate. The rear air inlet 40i is used to introduce air into the interior of the control cabinet 100 for use with control devices 90 (see reference 90) disposed inside the control cabinet 100. Figure 5 The rear air inlet 40i is an air inlet (opening) for cooling the interior of the control cabinet 100, including the control cabinet 100. The rear air inlet 40i includes multiple openings arranged in a matrix. The rear ventilation port 41i includes multiple openings arranged in a row, configured to ventilate the interior of the control cabinet 100. The rear wiring hole cover 40g, rear wiring hole cover 41g, and rear wiring hole cover 42g are covers that cover the openings in the rear member 40 for wiring to pass through. The rear wiring hole cover 40g, rear wiring hole cover 41g, and rear wiring hole cover 42g are, for example, cable loops.

[0040] The rear air inlet 40i, rear wiring hole cover 40g, rear wiring hole cover 41g, and rear wiring hole cover 42g are disposed near the center of the rear member 40 in the vertical direction (Z direction). Furthermore, "near the center of the rear member 40" is a broad concept encompassing not only the center of the rear member 40 itself but also its periphery. The first mounting portion 40n, the second mounting portion 41n, and the third mounting portion 42n are each provided with holes for inserting a fixing member (not shown), which will be used to mount the machine compartment mounting surface 231 of the control panel 100 (see reference). Figure 4 It is fixed to the control cabinet 100.

[0041] The top surface member 50 includes a top surface vent 50i. The top surface member 50 is disposed on the top surface of the control cabinet 100 and is formed of a metal plate. The top surface vent 50i is used to vent the control equipment 90 (see reference 100) disposed inside the control cabinet 100. Figure 5 The exhaust port (opening) is where air introduced to cool the interior of the control cabinet 100, including the control cabinet 100, is discharged to the outside of the control cabinet 100. Furthermore, the top exhaust port 50i is an example of the "first exhaust port" in the claims.

[0042] The first bottom component 60 is provided with a bottom wiring hole cover 60g and a bottom wiring hole cover 61g. The first bottom component 60 is located on the bottom side (Z2 side) of the control cabinet 100 and is formed of a metal plate. The bottom wiring hole cover 60g and the bottom wiring hole cover 61g are covers that cover the openings of the first bottom component 60 for wiring to pass through. The bottom wiring hole cover 60g and the bottom wiring hole cover 61g are, for example, cable loops.

[0043] The front component 10, right side component 20, left side component 30, back component 40, top component 50, and first bottom component 60 are all independent metal plate components.

[0044] (Status of the control cabinet located in the machine room)

[0045] Next, refer to Figures 3-5 To illustrate the state of the control cabinet 100 located in the machine room 230 in this embodiment.

[0046] like Figure 4 As shown, when the control cabinet 100 is installed inside the machine room 230, it is mounted on the machine room mounting surface 231 (shaded area) extending vertically (Z direction) from the floor of the machine room 230. At this time, by means of the first mounting portion 40n, the second mounting portion 41n, and the third mounting portion 42n (see reference...) Figure 3A fixing member (not shown) is inserted into the hole of the control cabinet 100 to fix the machine room mounting surface 231 to the control cabinet 100, thereby installing the control cabinet 100. In addition, the control cabinet 100 is installed such that the bottom surface of the control cabinet 100 (first bottom surface member 60) is separated from the floor of the machine room 230 by a predetermined distance D in the vertical direction (Z-axis direction).

[0047] In this embodiment, when the control cabinet 100 is located inside the machine room 230, the rear air inlet 40i is adjacent to the machine room mounting surface 231, thus the machine room mounting surface 231 becomes an obstacle. This obstructs the view of the control device 90 (see reference 40i). Figure 5 The function of introducing air to cool the interior of the control cabinet 100, including the control equipment 90, is reduced, making it almost impossible to introduce air for cooling the interior of the control cabinet 100. On the other hand, the right-side air inlet 20i and the left-side air inlet 30i (see reference) Figure 3 Since there are no adjacent obstacles, the function of introducing air to cool the interior of the control cabinet 100, including the control device 90, is not diminished, thus enabling the introduction of an amount of air sufficient to cool the interior of the control cabinet 100, including the control device 90. In this embodiment, the area obtained by combining the area of ​​the right-side air inlet 20i and the area of ​​the left-side air inlet 30i is the area capable of introducing an amount of air sufficient to cool the interior of the control cabinet 100, including the control device 90. Furthermore, the right-side air inlet 20i and the left-side air inlet 30i are examples of the "first air inlet" or "second air inlet" as described in the claims. Additionally, the rear air inlet 40i is an example of the "first air inlet" or "second air inlet" as described in the claims.

[0048] (Airflow inside the control cabinet located in the machine room)

[0049] Next, refer to Figure 4 and Figure 5 To illustrate the airflow inside the control cabinet 100 located in the machine room 230 of this embodiment.

[0050] like Figure 5 As shown, a control device 90 for controlling the elevator 200 is disposed inside the control cabinet 100. The control device 90 includes a frequency converter unit 91, a circuit breaker 94, an operating unit 95, and a battery 96. The frequency converter unit 91 internally includes frequency converter circuitry (not shown). Additionally, the frequency converter unit 91 includes a cooling fan 92 and cooling fins 93. Multiple circuit breakers 94, batteries 96, and cooling fins 93 are provided. Figure 5 In (a), the front panel 10 is made transparent to easily illustrate the airflow inside the control cabinet 100. Additionally, in Figure 5In (b), the right side component 20 is made transparent in order to easily illustrate the airflow inside the control cabinet 100.

[0051] The cooling fan 92 is a fan that circulates air. In this embodiment, the cooling fan 92 causes air to flow upward (Z1 direction) in the vertical direction. The air flowing through the cooling fan 92 is introduced from the right side air inlet 20i and the left side air inlet 30i. The air introduced from the right side air inlet 20i and the left side air inlet 30i passes through the first air guide path 150 and is discharged from the top exhaust port 50i. The first air guide path 150 includes a fin ventilation path 151 passing through the cooling fins 93. The cooling fins 93 are fins provided with a plurality of plate-shaped members extending in a direction orthogonal to the left-right direction (X-axis direction) when the control cabinet 100 is viewed from the front. The fin ventilation path 151 is the space between the plurality of fins. Two cooling fins 93 are provided in a manner that separates them from each other in the vertical direction (Z direction), and the cooling fin 93 on the upper side (Z1 side) in the vertical direction has a greater length in the vertical direction.

[0052] In this embodiment, the right side air inlet 20i and the left side air inlet 30i are positioned below the inverter unit 91 (Z2 direction) in the vertical direction (Z direction). The inverter unit 91 is cooled using air passing through the first airflow path 150. As described above, the rear air inlet 40i is located below the machine room mounting surface 231 (see reference). Figure 4 The air is blocked, making it almost impossible to introduce air. In other words, in this embodiment, when the control cabinet 100 is installed inside the machine room 230, air is introduced from the two side sides (X1 side and X2 side) and air is discharged from the top side (Z1 side).

[0053] In this embodiment, inside the control cabinet 100, the area of ​​the cross-section of the first air guide path 150 along a direction orthogonal to the direction of airflow introduced from the right side air inlet 20i and the left side air inlet 30i is the smallest among the cross-sectional areas of the finned ventilation path 151. Furthermore, the cross-sectional areas of the two finned ventilation paths 151 are equal to each other. In this embodiment, the area obtained by summing the area of ​​the right side air inlet 20i and the area of ​​the left side air inlet 30i is greater than or equal to the cross-sectional area of ​​the finned ventilation path 151. Moreover, the finned ventilation path 151 is an example of the "ventilation path" as defined in the claims.

[0054] The circuit breaker 94 is, for example, a wiring cutter capable of automatically disconnecting the circuit in the event of abnormal accidents such as short circuits and overload currents. Furthermore, the operating unit 95 is configured to include switches and the like, enabling manual or automatic operation for controlling the elevator 200. Additionally, a baffle 97 is disposed below the operating unit 95 in the vertical direction (Z2 direction). The baffle 97 is a flat plate extending in a direction orthogonal to the vertical direction (Z direction). The baffle 97 partially separates the space above (Z1 direction) and below (Z2 direction) of the baffle 97 in the vertical direction. The battery 96 is, for example, a battery that supplies power to other devices of the control equipment 90 during a power outage. The battery 96 may release corrosive gases; therefore, to prevent damage to other devices of the control equipment 90 due to the released corrosive gases, the space where the battery 96 is disposed is partially separated from the space where other devices of the control equipment 90 are disposed by the baffle 97, thereby suppressing the movement of active air.

[0055] The rear ventilation port 41i is located below the baffle plate 97 in the vertical direction (Z direction) (Z2 direction) to ventilate the space below the baffle plate 97 in the vertical direction (Z2 direction). In other words, the rear ventilation port 41i ventilates the space where the battery 96 is located. In addition, since the area of ​​the rear ventilation port 41i is smaller than the area of ​​the cross-section of the fin ventilation path 151 and there is a baffle plate 97, air is hardly actively introduced from the rear ventilation port 41i by airflow from the cooling fan 92.

[0056] In this embodiment, the battery 96 is positioned vertically (Z direction) below the right side air inlet 20i and the left side air inlet 30i (Z2 direction). Air heated by the battery 96 rises vertically upward (Z1 direction) along the forward circulation path 160. Then, the air reaching the lower vertical ends (Z2 side ends) of the right side air inlet 20i and the left side air inlet 30i is cooled by the air (external air) introduced from the right side air inlet 20i and the left side air inlet 30i, and thus descends vertically downward (Z2 direction) along the reverse circulation path 161. As a result, the air heated by the battery 96 repeatedly rises and falls along the forward circulation path 160 and the reverse circulation path 161. This rising and falling of air creates air convection, thereby cooling the circuit breaker 94, the operating unit 95, and the battery 96.

[0057] Here, the forward circulation path 160 refers to the space (passage) where air heated by the battery 96 rises inside the control cabinet 100. Conversely, the reverse circulation path 161 refers to the space (passage) where the air that has risen along the forward circulation path 160 descends toward the battery 96 after being cooled.

[0058] The air passing through the first airflow path 150 and the air passing through the forward circulation path 160 and the reverse circulation path 161 hardly mix. Therefore, even if the air passing through the forward circulation path 160 and the reverse circulation path 161 contains corrosive gases released from the battery 96, the air passing through the first airflow path 150 will hardly contain any corrosive gases, so the inverter unit 91 will not be damaged by the corrosive gases released from the battery 96.

[0059] As described above, the inverter unit 91, which has the highest cooling priority in the control device 90, is directly cooled by air introduced by the cooling fan 92. Other devices in the control device 90, excluding the inverter unit 91, are indirectly cooled by convection of air cooled by the air introduced by the cooling fan 92, thereby cooling the entire control device 90. Furthermore, in this embodiment, the right-side air inlet 20i and the left-side air inlet 30i have areas capable of introducing an amount of air sufficient to cool the entire control device 90. Moreover, the air introduced from the right-side air inlet 20i and the left-side air inlet 30i not only cools the control device 90 but also cools the interior of the control cabinet 100, including the control device 90. In this embodiment, the right-side air inlet 20i and the left-side air inlet 30i have areas capable of introducing an amount of air sufficient to cool the interior of the control cabinet 100.

[0060] (Structure of the control cabinet when it is located within the lifting path)

[0061] Next, refer to Figures 6-9 The structure of the control cabinet 100 in this embodiment, which is set within the lifting path 220, will be explained.

[0062] like Figure 6 and Figure 7 As shown, the control cabinet 100 includes a front component 10, a right side component 20, a left side component 30, a rear component 40, a top component 50, a wind tunnel section 70, a second bottom component 80, and control equipment 90 (see reference). Figure 9 In other words, the front member 10, right side member 20, left side member 30, rear member 40, and top member 50 of the control cabinet 100 located in the machine room 230 and the control cabinet 100 located in the lifting path 220 are common. Furthermore, the same reference numerals are used for structures common to the control cabinet 100 located in the machine room 230, and repeated descriptions are omitted. Additionally, the front member 10, right side member 20, left side member 30, rear member 40, top member 50, wind tunnel section 70, and second bottom member 80 are examples of the "shell" as described in the claims.

[0063] like Figure 6 and Figure 7 As shown, the wind tunnel section 70 is located above the top member 50 in the vertical direction (Z1 side). Regarding the wind tunnel section 70, the surface facing the top member 50 is formed as an opening, and the other five surfaces are formed of flat metal, i.e., metal plates. The wind tunnel section 70 includes a right-side exhaust port 70i, a left-side exhaust port 71i, and a rear-side exhaust port 72i, and is equipped with a left-side wiring hole cover 70g and a rear-side wiring hole cover 71g.

[0064] The right-side exhaust port 70i of the wind tunnel is located on the right side (X1 side) of the wind tunnel section 70. The left-side exhaust port 71i of the wind tunnel is located on the left side (X2 side) of the wind tunnel section 70. The rear-side exhaust port 72i of the wind tunnel is located on the rear side (Y1 side) of the wind tunnel section 70. The right-side exhaust port 70i, the left-side exhaust port 71i, and the rear-side exhaust port 72i are exhaust ports for discharging air discharged from the top exhaust port 50i to the outside of the control cabinet 100.

[0065] In this embodiment, the wind tunnel section 70 is configured to cover the top exhaust port 50i, thereby changing the direction of airflow discharged from the top exhaust port 50i. The airflow inside the wind tunnel section 70 will be described later. Furthermore, in this embodiment, the wind tunnel section 70 does not have an exhaust port (opening) on ​​the top side (Z1 side). This prevents water droplets and dust falling from the vertical direction (Z1 direction) that form due to condensation from entering the interior of the control cabinet 100. Moreover, in this embodiment, the wind tunnel section 70 is configured to overlap with the top member 50 when viewed from the vertical direction (Z1 direction), thereby effectively preventing water droplets and dust falling from the vertical direction (Z1 direction) that form due to condensation from entering the interior of the control cabinet 100.

[0066] The wind tunnel right-side exhaust port 70i, the wind tunnel left-side exhaust port 71i, and the wind tunnel rear-side exhaust port 72i include a plurality of openings arranged in a matrix. The wind tunnel left-side wiring hole cover 70g and the wind tunnel rear-side wiring hole cover 71g are covers that cover the openings on the left and rear sides of the wind tunnel section to allow wiring, etc., to pass through. The wind tunnel left-side wiring hole cover 70g and the wind tunnel rear-side wiring hole cover 71g are, for example, cable loops. Furthermore, the wind tunnel right-side exhaust port 70i, the wind tunnel left-side exhaust port 71i, and the wind tunnel rear-side exhaust port 72i are examples of the "second exhaust port" as claimed in the claims.

[0067] The second bottom component 80 is provided with four openings 80n for inserting a fixing component (not shown), which will be used to set the lifting path mounting surface 221 of the control cabinet 100 (see reference). Figure 8 It is fixed to the control cabinet 100.

[0068] That is, compared with the control cabinet 100 located in the machine room 230, the control cabinet 100 located in the lifting path 220 has an additional wind tunnel section 70, and the first bottom surface member 60 is changed to a second bottom surface member 80. In other words, in this embodiment, the front member 10, right side member 20, left side member 30, rear member 40, and top member 50 are common in both the control cabinet 100 located in the machine room 230 and the control cabinet 100 located in the lifting path 220. In addition, air inlets (right side air inlet 20i, left side air inlet 30i, and rear air inlet 40i) and wiring holes are provided at common positions in both the control cabinet 100 located in the machine room 230 and the control cabinet 100 located in the lifting path 220.

[0069] The front component 10, right side component 20, left side component 30, rear component 40, top component 50, wind tunnel section 70, and second bottom component 80 are all independent metal plate components. Furthermore, in this embodiment, the right side air inlet 20i and the left side air inlet 30i are located on different sides of the housing of the control cabinet 100 extending in the vertical direction (Z direction), and the rear air inlet 40i is located on the rear side of the housing of the control cabinet 100 extending in the vertical direction (Z direction). In other words, in this embodiment, the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i are located on different sides, the front (front face), and the rear face of the housing of the control cabinet 100 extending in the vertical direction (Z direction).

[0070] (Status of the control cabinet located within the lifting path)

[0071] Next, refer to Figures 7-9 To illustrate the state of the control cabinet 100 located within the lifting path 220 in this embodiment.

[0072] like Figure 8 As shown, when the control cabinet 100 is installed within the lifting path 220, it is installed on the lifting path mounting surface 221 (shaded area) within the lifting path 220. At this time, by extending the control cabinet 100 into the opening 80n provided on the second bottom member 80... Figure 7(Referring to) Inserting a fixing member (not shown) to fix the lifting path mounting surface 221 to the control cabinet 100, thereby installing the control cabinet 100. Regarding the control cabinet 100 installed within the lifting path 220, its rear side (Y1 side) and top side (Z1 side) face the lifting path 220, and its front side (Y2 side) faces the elevator hall 240. The elevator hall 240 is a space in a building or similar structure where the elevator 200 is installed, for users of the elevator to go up and down the elevator. Furthermore, the side sides (X1 side and X2 side) of the control cabinet 100 installed within the lifting path 220 face the structure 250 between the lifting path 220 and the elevator hall 240. For ease of explanation, in Figure 8 Although the end face of the structure 250 in the vertical direction (Z1 side) can be observed, in reality, the structure 250 extends along the vertical direction (Z direction) to the end face of the lifting path 220 in the vertical direction (Z1 side).

[0073] In this embodiment, when the control cabinet 100 is located within the lifting path 220, the right side air inlet 20i (refer to...) Figure 7 ) and the left side air intake 30i (refer to Figure 7 The structure 250 is adjacent to the structure 250, thus the structure 250 becomes an obstacle, in order to access the control device 90 (see reference). Figure 9 The function of introducing air to cool the interior of the control cabinet 100, including the control equipment 90, is reduced, making it almost impossible to introduce air for cooling the interior of the control cabinet 100. On the other hand, the rear air inlet 40i (see reference) Figure 7 Since there are no adjacent obstacles, the function of introducing air to cool the interior of the control cabinet 100, including the control device 90, is not diminished, thus enabling the introduction of an amount of air sufficient to cool the interior of the control cabinet 100, including the control device 90. In this embodiment, the area of ​​the rear air inlet 40i is the area sufficient to introduce an amount of air sufficient to cool the interior of the control cabinet 100, including the control device 90. Furthermore, the right side air inlet 20i and the left side air inlet 30i are examples of the "first air inlet" or "second air inlet" as described in the claims. Additionally, the rear air inlet 40i is an example of the "first air inlet" or "second air inlet" as described in the claims.

[0074] In addition, in this embodiment, when the control cabinet 100 is located within the lifting path 220, the exhaust port 70i on the right side of the wind tunnel and the exhaust port 71i on the left side of the wind tunnel (see reference) Figure 7 The structure 250 is adjacent to the control cabinet 100, thus the structure 250 becomes an obstruction, reducing the ability to exhaust air from the control cabinet 100, making it almost impossible to exhaust air from the control cabinet 100. On the other hand, the exhaust port 72i at the back of the wind tunnel (see reference) Figure 7There are no adjacent obstacles, so the function of exhausting air from the inside of the control cabinet 100 is not reduced, thereby enabling the air introduced into the control cabinet 100 to be cooled, including the control equipment 90. Figure 9 (Refer to) A certain amount of air inside the control cabinet 100 is discharged to the outside of the control cabinet 100.

[0075] (Airflow inside the control cabinet located within the lifting path)

[0076] Next, refer to Figure 8 and Figure 9 The airflow inside the control cabinet 100 located within the lifting path 220 in this embodiment will be explained. Furthermore, for structures identical to the control cabinet 100 located in the machine room 230, the same reference numerals will be used, and repeated descriptions will be omitted.

[0077] exist Figure 9 In (a), the front side (Y2 side) of the front member 10 and the wind tunnel section 70 are made transparent to illustrate the airflow inside the control cabinet 100. Additionally, in Figure 9 In (b), the right side panel 20 and the right side (X1 side) of the wind tunnel section 70 are made transparent in order to illustrate the airflow inside the control cabinet 100.

[0078] like Figure 9 As shown, the air flowing via the cooling fan 92 is introduced from the rear air inlet 40i. The air introduced from the rear air inlet 40i passes through the second air guide path 152 and is discharged from the top exhaust port 50i. This second air guide path 152 includes a fin ventilation path 151 passing through the cooling fins 93. The air discharged from the top exhaust port 50i passes through the wind tunnel section 70 and is discharged from the rear exhaust port 72i of the wind tunnel. In this embodiment, the wind tunnel section 70 is configured to cover the top exhaust port 50i, thereby changing the direction of airflow from the top exhaust port 50i. Specifically, in this embodiment, the wind tunnel section 70 is configured to cover the top exhaust port 50i, thereby changing the direction of airflow from the top exhaust port 50i from a direction facing vertically upwards (Z1 direction) to a direction from the front of the control cabinet 100 towards the rear (Y1 direction).

[0079] In this embodiment, the rear air inlet 40i is positioned below the inverter unit 91 (Z2 direction) in the vertical direction (Z direction). The inverter unit 91 is cooled by air passing through the second air guide path 152. At this time, the right side air inlet 20i and the left side air inlet 30i are constructed by the structure 250 (see reference 250) as described above. Figure 8The air is blocked, making it almost impossible to introduce air. In other words, in this embodiment, when the control cabinet 100 is located within the lifting path 220, air is introduced from the rear side (Y1 side) and air is discharged from the rear side (Y1 side).

[0080] In this embodiment, inside the control cabinet 100, the area of ​​the cross-section of the second air guide path 152 along a direction orthogonal to the direction of airflow introduced from the rear air inlet 40i is the smallest among all the cross-sectional areas of the finned ventilation path 151. Here, the cross-sectional areas of the plurality of finned ventilation paths 151 are equal to each other. In this embodiment, the area of ​​the rear air inlet 40i is greater than or equal to the area of ​​the cross-section of the finned ventilation path 151. Furthermore, the finned ventilation path 151 is an example of the "ventilation path" as defined in the claims.

[0081] In this embodiment, the battery 96 is positioned below (Z2 direction) the rear air inlet 40i in the vertical direction (Z direction). The airflow below (Z2 direction) of the rear air inlet 40i in the vertical direction repeatedly rises and falls, generating convection, similar to the case described above where it is located within the machine room 230. However, with the control cabinet 100 located within the lifting path 220, the right-side air inlet 20i and the left-side air inlet 30i can hardly draw in any air. Therefore, the air rising vertically upwards (Z1 direction) along the forward circulation path 160 is cooled by the air (external air) drawn in from the rear air inlet 40i, and thus descends vertically downwards (Z2 direction) along the reverse circulation path 161. Here, the air passing through the second air guide path 152 and the air passing through the forward circulation path 160 and the reverse circulation path 161 hardly mix. Therefore, even if the air passing through the forward circulation path 160 and the reverse circulation path 161 contains corrosive gases released from the battery 96, the air passing through the second air guide path 152 will contain almost no corrosive gases, so the inverter unit 91 will not be damaged by the corrosive gases released from the battery 96.

[0082] As described above, the inverter unit 91, which has the highest cooling priority in the control device 90, is directly cooled by air introduced by the cooling fan 92. Other devices in the control device 90, excluding the inverter unit 91, are indirectly cooled by convection of air cooled by the air introduced by the cooling fan 92, thereby cooling the entire control device 90. Furthermore, in this embodiment, the rear air inlet 40i has an area capable of introducing an amount of air sufficient to cool the entire control device 90. In addition, the air introduced from the rear air inlet 40i not only cools the control device 90 but also cools the interior of the control cabinet 100, including the control device 90. In this embodiment, the rear air inlet 40i has an area capable of introducing an amount of air sufficient to cool the interior of the control cabinet 100.

[0083] (Effects of this implementation method)

[0084] Next, the effects of this implementation method will be explained.

[0085] In this embodiment, as described above, the housing includes: a right-side air inlet 20i and a left-side air inlet 30i having areas capable of introducing an amount of air capable of cooling the interior of the housing within the machine chamber 230; and a rear air inlet 40i having an area capable of introducing an amount of air capable of cooling the interior of the housing within the lifting path 220. Therefore, it is not necessary to change (design separately) the positions of the air inlets for at least two different installation environments where the machine chamber 230 and lifting path 220 are different. As a result, the effort and time required to construct the housing for each installation environment can be reduced.

[0086] Furthermore, in this embodiment, as described above, the housing includes a ventilation path through which air introduced from at least one of the right-side air inlet 20i, the left-side air inlet 30i, and the rear air inlet 40i flows. The areas of the right-side air inlet 20i, the left-side air inlet 30i, and the rear air inlet 40i are greater than or equal to the area of ​​the cross-section of the ventilation path. Therefore, the right-side air inlet 20i, the left-side air inlet 30i, and the rear air inlet 40i can have relatively large areas, thus allowing for easy introduction of an amount of air sufficient to adequately cool the control device regardless of the installation environment.

[0087] Furthermore, in this embodiment, as described above, the housing has a rectangular parallelepiped shape that extends vertically, and the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i are provided on different sides, the front side, and the back side of the housing that extend vertically. This reduces the effort and time required to design the components that constitute the relatively large areas of the sides, front side, and back side of the housing. Additionally, it reduces the variety of components that make up the housing, thus improving productivity.

[0088] Furthermore, in this embodiment, as described above, the housing includes a top surface exhaust port 50i disposed on the top surface of the housing and discharging air to the outside of the housing, and includes a wind tunnel section 70 that changes the direction of airflow discharged from the top surface exhaust port 50i by being configured to cover the top surface exhaust port 50i. Therefore, compared to the case without the wind tunnel section 70, the direction of airflow discharged from the top surface exhaust port 50i can be easily changed according to each installation environment. As a result, it is not necessary to design exhaust ports separately for each installation environment, thus easily reducing the effort and time required to design exhaust ports in the construction of the housing for each installation environment.

[0089] Furthermore, in this embodiment, as described above, regarding the wind tunnel section 70, a right-side exhaust port 70i, a left-side exhaust port 71i, and a rear-side exhaust port 72i are provided on the back and sides of the wind tunnel section 70 for discharging air discharged from the top exhaust port 50i, while no exhaust port is provided on the top surface of the wind tunnel section 70. Therefore, since no exhaust port is provided on the top surface of the control cabinet 100, it is possible to prevent water droplets formed by condensation or other factors falling from above and dust from entering the interior and damaging the control equipment 90.

[0090] Furthermore, in this embodiment, as described above, the housing includes a top exhaust port 50i disposed on the top surface of the housing and discharging air to the outside of the housing. The control device 90 includes an inverter unit 91, which has a cooling fan 92 located above it in the vertical direction. A right side air inlet 20i, a left side air inlet 30i, and a rear air inlet 40i are disposed below the inverter unit 91 in the vertical direction. Thus, regardless of the installation environment, the inverter unit 91, which has a higher cooling priority, can be directly cooled using air introduced from at least one of the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i.

[0091] Furthermore, in this embodiment, as described above, the control device 90 also includes a battery 96, which is vertically disposed below the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i. As a result, air heated by the battery 96 rises to the positions of the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i, is cooled by contact with air introduced from at least one of the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i, and then descends to the position of the battery 96. As a result, not only is the control device 90 (inverter unit 91) located above the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i cooled, but the control device 90 located below the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i is also cooled by air convection between the battery 96 and the air between the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i. Therefore, damage to the inverter unit 91 due to corrosive gases that may be released from the battery 96 can be suppressed, and the entire control device 90 can be cooled by air introduced from at least one of the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i.

[0092] Furthermore, in this embodiment, as described above, the control device 90 includes an inverter unit 91 with cooling fins 93, and the cross-sectional area of ​​the ventilation path is equal to the ventilation area of ​​the cooling fins 93. Therefore, compared to cases where the areas of the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i are smaller than the ventilation area of ​​the cooling fins 93, the amount of air passing through the cooling fins 93 increases. As a result, regardless of the installation environment, the inverter unit 91, which has a higher cooling priority, can be efficiently cooled using air introduced from at least one of the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i.

[0093] Furthermore, in this embodiment, as described above, the first installation environment is either within the elevator's lifting path 220 or within the machine room 230, which is separate from the elevator's lifting path 220; the second installation environment is the other of the two: within the elevator's lifting path 220 and within the machine room 230, which is separate from the elevator's lifting path 220. This reduces the effort and time required to construct the housing for both the elevator's lifting path 220 (where the control cabinet 100 is highly likely to be installed) and the machine room 230 (separate from the elevator's lifting path 220). Consequently, the effort and time required to construct the housing for each installation environment can be effectively reduced.

[0094] [Variation Example]

[0095] Furthermore, it should be considered that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the invention is not defined by the description of the embodiments above, but by the claims, and includes all modifications (variations) within the meaning and scope equivalent to the claims.

[0096] For example, in this embodiment, an example is shown where the area of ​​the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i is greater than or equal to the area of ​​the cross-section of the fin ventilation path 151; however, the present invention is not limited thereto. For example, the area of ​​the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i may also be smaller than the area of ​​the cross-section of the fin ventilation path 151.

[0097] Furthermore, in this embodiment, an example is shown where the housing has a cuboid shape that is elongated in the vertical direction, and the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i are provided on different faces of the side, front, and back of the housing that extend in the vertical direction. However, the present invention is not limited to this. For example, the housing may also have a cuboid shape that is elongated in the horizontal direction, and the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i may also be provided on the same faces of the side, front, and back of the housing that extend in the vertical direction.

[0098] Furthermore, in this embodiment, an example is shown where the housing of the control cabinet 100 includes a wind tunnel section 70 that changes the direction of airflow discharged from the top surface exhaust port 50i by being configured to cover the top surface exhaust port 50i; however, the present invention is not limited thereto. For example, the housing of the control cabinet 100 may not include the wind tunnel section 70.

[0099] Furthermore, in this embodiment, the following example is shown: regarding the wind tunnel section 70, no exhaust port is provided on the top surface of the wind tunnel section 70, but the present invention is not limited thereto. For example, the wind tunnel section 70 may also be configured to have an exhaust port provided on the top surface of the wind tunnel section 70, and a cover to prevent water droplets and dust from entering may be provided on the upper part as needed.

[0100] Furthermore, in this embodiment, an example is shown where the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i are positioned below the inverter unit 91 in the vertical direction; however, the present invention is not limited thereto. For example, the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i may also be positioned above the inverter unit 91 in the vertical direction.

[0101] Furthermore, in this embodiment, an example is shown where the battery 96 is positioned vertically below the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i; however, the invention is not limited thereto. For example, the battery 96 may also be positioned vertically above the right side air inlet 20i, the left side air inlet 30i, and the rear air inlet 40i.

[0102] Furthermore, in this embodiment, an example is shown where the control cabinet 100 is installed within the elevator's lifting path 220 and within a machine room 230 separate from the elevator's lifting path 220; however, the present invention is not limited thereto. For example, the control cabinet 100 may also be installed in an environment other than within the elevator's lifting path 220 and within a machine room 230 separate from the elevator's lifting path 220.

[0103] Furthermore, this embodiment shows an example where the control cabinet 100 is located within the machine room 230 and does not include the wind tunnel section 70; however, the invention is not limited to this. For example, the control cabinet 100 may also include the wind tunnel section 70 when located within the machine room 230. In this case, the exhaust port 72i on the back of the wind tunnel is adjacent to the machine room mounting surface 231, thus the machine room mounting surface 231 becomes an obstruction, reducing the ability to exhaust air from the inside of the control cabinet 100, making it almost impossible to exhaust air from the inside of the control cabinet 100. Therefore, air is exhausted from the exhaust port 70i on the right side of the wind tunnel and the exhaust port 71i on the left side of the wind tunnel.

[0104] Furthermore, in this embodiment, an example is shown where the housing of the control cabinet 100 is formed of a metal plate, but the present invention is not limited thereto. For example, the housing of the control cabinet 100 may also be formed of a resin or the like, which are materials other than metal.

[0105] Furthermore, in this embodiment, an example is shown where the front member 10 includes an upper front member 10a and a lower front member 10b, but the invention is not limited thereto. For example, the front member 10 may also be a single member.

[0106] In addition, in this embodiment, an example is shown in which the front member 10, right side member 20, left side member 30, back member 40, top member 50 and first bottom member 60 are each independent metal plate members when the control cabinet 100 is installed in the machine room 230, and in which the front member 10, right side member 20, left side member 30, back member 40, top member 50, wind tunnel section 70 and second bottom member 80 are each independent metal plate members. However, the present invention is not limited to this. For example, when the control cabinet 100 is located in the machine room 230, at least two of the front component 10, right side component 20, left side component 30, back component 40, top component 50, and first bottom component 60 may be the same metal plate component. When the control cabinet 100 is located in the lifting path 220, at least two of the front component 10, right side component 20, left side component 30, back component 40, top component 50, wind tunnel section 70, and second bottom component 80 may also be the same metal plate component.

[0107] Furthermore, in this embodiment, an example is shown where the right side air inlet 20i, left side air inlet 30i, rear air inlet 40i, rear ventilation inlet 41i, right side exhaust outlet 70i, left side exhaust outlet 71i, and rear exhaust outlet 72i of the wind tunnel include multiple openings; however, the present invention is not limited thereto.
