Abstract
Description
[Technical Field]
[0001] The present invention relates to an elevator control panel, and more particularly to an elevator control panel whose interior is cooled by air introduced through an air intake port. [Background technology]
[0002] BACKGROUND ART Conventionally, elevator control panels are known in which the interior is cooled by air introduced through an air intake port (see, for example, Patent Document 1).
[0003] The above-mentioned Patent Document 1 discloses a control panel that manages the drive motor of an elevator system and each device that constitutes the elevator system. The control panel of the above-mentioned Patent Document 1 forms a cooling flow path that cools the forced air-cooled devices and natural cooling devices (control devices) by taking in outside air through an air intake and expelling it from an exhaust port. The control panel of the above-mentioned Patent Document 1 is placed inside the elevator system's hoistway or inside a machine room installed separately from the hoistway. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] International Publication No. 2017 / 141311 Summary of the Invention [Problem to be solved by the invention]
[0005] However, the control panel described in Patent Document 1 may require different positions of the intake and exhaust ports and different installation methods depending on whether the control panel is placed inside a hoistway or inside a machine room. In other words, the control panel described in Patent Document 1 may require time and effort to individually design the housing structure for each installation environment. The time and effort required to individually design the housing structure required for each installation environment reduces productivity. Therefore, there is a demand for a control panel (elevator control panel) that can reduce the time and effort required to design the housing structure required for each installation environment.
[0006] The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to provide an elevator control panel that can reduce the effort and time required to design the housing structure required for each installation environment. [Means for solving the problem]
[0007] In order to achieve the above object, an elevator control panel according to one aspect of the present invention is an elevator control panel having a control device disposed therein for controlling the operation of the elevator, the elevator control panel being installed in at least a first installation environment and a second installation environment, the elevator control panel including a housing in which the control device is disposed, the housing including a first air intake section having an area capable of introducing a quantity of air sufficient to cool the interior of the housing in the first installation environment, and a second air intake section having an area capable of introducing a quantity of air sufficient to cool the interior of the housing in the second installation environment.
[0008] In the elevator control panel according to this aspect, as described above, the housing includes a first air intake section having an area capable of introducing a quantity of air sufficient to cool the interior of the housing in a first installation environment, and a second air intake section having an area capable of introducing a quantity of air sufficient to cool the interior of the housing in a second installation environment. This eliminates the need to change the position of the air intake port (design it individually) for at least two different installation environments, i.e., the first installation environment and the second installation environment. As a result, it is possible to reduce the effort and time required to design the housing structure required for each installation environment.
[0009] In the elevator control panel according to the above aspect, the housing preferably includes a ventilation passage through which air introduced from at least one of the first air intake section and the second air intake section flows, and the area of the first air intake section and the area of the second air intake section are equal to or greater than the area of a cross section of the ventilation passage. With this configuration, the first air intake section and the second air intake section can have relatively large areas, making it possible to easily introduce an amount of air sufficient to sufficiently cool the control device regardless of the installation environment.
[0010] In the elevator control panel according to the above aspect, the housing preferably has a rectangular parallelepiped shape that is elongated in the vertical direction, and the first air intake section and the second air intake section are provided on different surfaces among the side, front, and back surfaces of the housing that extend in the vertical direction. This configuration can reduce the effort and time required to design the components that make up the side, front, and back surfaces, which have relatively large areas within the housing. Furthermore, the number of types of components of the housing can be reduced, thereby improving productivity.
[0011] In the elevator control panel according to the above aspect, the housing preferably includes a first exhaust port provided on the top surface of the housing for exhausting air to the outside of the housing, and an air channel disposed to cover the first exhaust port and change the flow direction of the air exhausted from the first exhaust port. With this configuration, the flow direction of the air exhausted from the exhaust port can be easily changed for each installation environment, compared to a case in which the air channel is not included. As a result, there is no need to design an individual exhaust port for each installation environment, and the effort and time required to design the exhaust port, which is part of the housing structure required for each installation environment, can be easily reduced.
[0012] In this case, preferably, the air tunnel has second exhaust ports on the back and side of the air tunnel for discharging the air discharged from the first exhaust port, and no second exhaust port on the top surface of the air tunnel. With this configuration, no exhaust port is provided on the top surface of the elevator control panel, which makes it possible to prevent damage to the control equipment caused by water droplets due to condensation falling from above and dust entering the interior.
[0013] In the elevator control panel according to the above aspect, preferably, the housing includes a first exhaust port provided on a top surface of the housing for discharging air to the outside of the housing, the control device includes an inverter unit having a cooling fan provided vertically above, and the first and second intake ports are provided vertically below the inverter unit. With this configuration, the inverter unit, which has a relatively high priority for cooling, can be directly cooled by air introduced from at least one of the first and second intake ports, regardless of the installation environment.
[0014] In this case, preferably, the control device further includes a battery, and the battery is arranged vertically below the first and second intake sections. With this configuration, air heated by the battery rises to the positions of the first and second intake sections, comes into contact with air introduced from at least one of the first and second intake sections, is cooled, and then descends to the position of the battery. As a result, in addition to the control device (inverter unit) arranged above the first and second intake sections, the control device arranged below the first and second intake sections is also cooled by air convection between the battery and the first and second intake sections. This prevents damage to the inverter unit due to corrosive gas that may be released from the battery, and allows the entire control device to be cooled by air introduced from at least one of the first and second intake sections.
[0015] In the elevator control panel, the housing includes a ventilation passage through which air introduced from at least one of the first and second intake sections flows, and the areas of the first and second intake sections are equal to or larger than the cross-sectional area of the ventilation passage. Preferably, the control device includes an inverter unit with cooling fins, and the cross-sectional area of the ventilation passage is equal to the ventilation area of the cooling fins. This configuration increases the amount of air passing through the cooling fins compared to when the areas of the first and second intake sections are smaller than the ventilation area of the cooling fins. As a result, the inverter unit, which has a relatively high cooling priority, can be efficiently cooled by air introduced from at least one of the first and second intake sections, regardless of the installation environment.
[0016] In the elevator control panel according to the above aspect, the first installation environment is preferably either one of an elevator hoistway or a machine room installed separately from the elevator hoistway, and the second installation environment is the other of an elevator hoistway or a machine room installed separately from the elevator hoistway. This configuration can reduce the effort and time required to design the required housing structure in the elevator hoistway and the machine room installed separately from the elevator hoistway, where the elevator control panel is likely to be installed. As a result, the effort and time required to design the required housing structure for each installation environment can be efficiently reduced. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION
[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.
[0020] [Embodiment] (Elevator configuration) The overall configuration of an elevator 200 according to this embodiment will be described with reference to FIG.
[0021] As shown in FIG. 1, elevator 200 is a device installed in a building or the like, for vertically moving people or cargo loaded in car 211. Elevator 200 includes car 211 and weight 212 installed in hoistway 220, lifting system 210 installed across hoistway 220 and machine room 230, and control panel 100 installed in hoistway 220 or machine room 230. However, due to restrictions on the building in which elevator 200 is installed, there may be no machine room 230. In that case, car 211, weight 212, lifting system 210, and control panel 100 are all installed within hoistway 220. Note that control panel 100 is an example of an "elevator control panel" in the claims.
[0022] The elevator system 210 is a system that uses a weight 212 or the like to raise and lower the car 211 in the vertical direction. The elevator shaft 220 is a space used for the elevator car 211 to ascend and descend, and is partitioned by a door to prevent people from entering except during maintenance. The machine room 230 is provided adjacent to and vertically above the elevator shaft 220, and a part of the elevator system 210 and the control panel 100 are disposed inside the machine room 230. The control panel 100 houses control devices for controlling the elevator system 210, and is installed in the machine room 230 (for example, at the position indicated by the solid line in FIG. 1) if the machine room 230 is present, or in the elevator shaft 220 (for example, at the position indicated by the dashed line in FIG. 1) if the machine room 230 is not present. The elevator shaft 220 and the machine room 230 are examples of one and the other of a "first installation environment" and a "second installation environment" in the claims.
[0023] (Configuration of control panel when installed in a machine room) Next, the configuration of the control panel 100 according to this embodiment when installed in the machine room 230 will be described with reference to FIGS.

The left-right direction (one direction in a horizontal plane) when viewing the control panel 100 from the front is defined as the X direction. The up-down direction (vertical direction) of the control panel 100 is defined as the Z direction. The direction perpendicular to the X and Z directions of the control panel 100 (the other direction in a horizontal plane) is defined as the Y direction.

The front member 10 includes an upper front member 10a and a lower front member 10b. The upper front member 10a is provided vertically above (on the Z1 side) the front side of the control panel 100. The lower front member 10b is separate from the upper front member 10a and is provided vertically below (on the Z2 side) the front side of the control panel 100. The upper front member 10a is provided to correspond to a space in which an inverter unit 91 (see FIG. 5) of a control device 90 (described later) is arranged, and the lower front member 10b is provided to correspond to a space in which control devices 90 (see FIG. 5) other than the inverter unit 91 are arranged. That is, when the upper front member 10a is removed, the inverter unit 91 is exposed, and when the lower front member 10b is removed, the control device 90 other than the inverter unit 91 is exposed.
[0026] The right side member 20 includes a right side air intake port 20i and is provided with a right side wiring hole cover 20g and a right side wiring hole cover 21g. The right side member 20 is provided on the right side (X1 side) of the control panel 100 when viewed from the front, and is formed of sheet metal. The right side air intake port 20i is an air intake port (opening) for introducing air into the control panel 100 to cool the interior of the control panel 100, including the control devices 90 (see FIG. 5) arranged therein. The right side air intake port 20i includes a plurality of openings arranged in a matrix. The right side wiring hole cover 20g and the right side wiring hole cover 21g are covers that cover openings provided in the right side member 20 for passing wires and the like. The right side wiring hole cover 20g is larger in size than the right side wiring hole cover 21g. The right side wiring hole cover 20g and the right side wiring hole cover 21g are, for example, grommets.
[0027] The right side surface air intake 20i, the right side surface wiring hole cover 20g, and the right side surface wiring hole cover 21g are provided on the right side surface member 20 in this order from above in the vertical direction (Z direction). The right side surface air intake 20i, the right side surface wiring hole cover 20g, and the right side surface wiring hole cover 21g are provided near the center of the right side surface member 20 in the vertical direction (Z direction). Note that the vicinity of the center of the right side surface member 20 is a broad concept that includes not only the center of the right side surface member 20 itself, but also the periphery of the center of the right side surface member 20. The right side surface air intake 20i, the right side surface wiring hole cover 20g, and the right side surface wiring hole cover 21g are provided closer to the rear side (Y1 side) of the right side surface member 20 in the depth direction (Y direction) of the control panel 100.
[0028] The left side surface member 30 includes a left side surface air intake port 30i and is provided with a left side surface wiring hole cover 30g. The left side surface member 30 is provided on the left side surface (X2 side) when viewed from the front of the control panel 100 and is formed of sheet metal. The left side surface air intake port 30i is an intake port (opening) for introducing air into the interior of the control panel 100 to cool the interior of the control panel 100, including the control devices 90 (see FIG. 5) arranged therein. The left side surface air intake port 30i includes multiple openings arranged in a matrix. The left side surface air intake port 30i and the right side surface air intake port 20i have the same shape and are provided at the same position in the vertical direction (Z direction). The left side surface wiring hole cover 30g is a cover that covers an opening provided in the left side surface member 30 for passing wiring and the like. The left side surface wiring hole cover 30g is, for example, a grommet.
[0029] The left side surface air intake 30i and the left side surface wiring hole cover 30g are provided on the left side surface member 30 in this order from top to bottom in the vertical direction (Z direction). The left side surface air intake 30i and the left side surface wiring hole cover 30g are provided near the center of the left side surface member 30 in the vertical direction (Z direction). Note that "near the center of the left side surface member 30" is a broad concept that includes not only the center of the left side surface member 30 itself but also the periphery of the center of the left side surface member 30. The left side surface air intake 30i and the left side surface wiring hole cover 30g are provided closer to the rear side (Y1 side) of the left side surface member 30 in the depth direction (Y direction) of the control panel 100.
[0030] The rear member 40 includes a rear air intake 40i, a rear ventilation opening 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 member 40 is provided on the rear side (Y1 side) of the control panel 100 and is formed of sheet metal. The rear air intake 40i is an intake port (opening) for introducing air into the control panel 100 to cool the interior of the control panel 100, including the control devices 90 (see FIG. 5) arranged therein. The rear air intake 40i includes a plurality of openings arranged in a matrix. The rear ventilation opening 41i includes a plurality of openings arranged in a row and is provided to ventilate the air inside the control panel 100. The rear wiring hole cover 40g, the rear wiring hole cover 41g, and the rear wiring hole cover 42g are covers that cover openings provided in the rear member 40 for passing wires and the like. The rear wiring hole cover 40g, the rear wiring hole cover 41g, and the rear wiring hole cover 42g are, for example, grommets.
[0031] The rear air intake 40i, rear wiring hole cover 40g, rear wiring hole cover 41g, and rear wiring hole cover 42g are provided near the center of the rear member 40 in the vertical direction (Z direction). Note that "near the center of the rear member 40" is a broad concept that includes not only the center of the rear member 40 itself but also the periphery of the center of the rear member 40. The first mounting portion 40n, the second mounting portion 41n, and the third mounting portion 42n each have a hole for inserting a fixing member (not shown) that fixes the control panel 100 to a machine room mounting surface 231 (see FIG. 4) on which the control panel 100 is installed.
[0032] The top surface member 50 includes a top surface exhaust port 50i. The top surface member 50 is provided on the top surface of the control panel 100 and is formed from sheet metal. The top surface exhaust port 50i is an exhaust port (opening) for discharging air introduced to the outside of the control panel 100 in order to cool the inside of the control panel 100, including the control devices 90 (see FIG. 5) arranged inside the control panel 100. The top surface exhaust port 50i is an example of a "first exhaust port" in the claims.
[0033] The first bottom surface member 60 is provided with a bottom surface wiring hole cover 60g and a bottom surface wiring hole cover 61g. The first bottom surface member 60 is provided on the bottom surface side (Z2 side) of the control panel 100 and is formed from sheet metal. The bottom surface wiring hole cover 60g and the bottom surface wiring hole cover 61g are covers that cover openings provided in the first bottom surface member 60 for passing wires and the like. The bottom surface wiring hole cover 60g and the bottom surface wiring hole cover 61g are, for example, grommets.
[0034] The front member 10, the right side member 20, the left side member 30, the back member 40, the top member 50 and the first bottom member 60 are each separate sheet metal members.
[0035] (Condition of the control panel installed in the machine room) Next, the state of the control panel 100 installed in the machine room 230 according to this embodiment will be described with reference to FIGS.
[0036] As shown in Fig. 4, when the control panel 100 is installed in the machine room 230, it is installed on a machine room installation surface 231 (hatched portion) that extends vertically (in the Z direction) from the floor of the machine room 230. At this time, the control panel 100 is installed by inserting fixing members (not shown) into holes provided in the first installation portion 40n, the second installation portion 41n, and the third installation portion 42n (see Fig. 3) to fix the machine room installation surface 231 and the control panel 100. In addition, the control panel 100 is installed with a predetermined distance D between the bottom surface (first bottom surface member 60) of the control panel 100 and the floor of the machine room 230 in the vertical direction (in the Z axis direction).
[0037] In this embodiment, when the control panel 100 is installed in a machine room 230, the rear air intake 40i is adjacent to the machine room installation surface 231, which becomes an obstacle. This reduces the function of introducing air to cool the interior of the control panel 100, including the control device 90 (see FIG. 5). As a result, the rear air intake 40i is unable to introduce much air to cool the interior of the control panel 100, including the control device 90. On the other hand, the right side air intake 20i and the left side air intake 30i (see FIG. 3) are not adjacent to any obstacles, so their function of introducing air to cool the interior of the control panel 100, including the control device 90, is not reduced, and they are able to introduce an amount of air that can cool the interior of the control panel 100, including the control device 90. In this embodiment, the sum of the area of the right side air intake 20i and the area of the left side air intake 30i is the area that can introduce an amount of air that can cool the interior of the control panel 100, including the control device 90. The right side air intake port 20i and the left side air intake port 30i are examples of the "first air intake section" or "second air intake section" in the claims. The rear air intake port 40i is also an example of the "first air intake section" or "second air intake section" in the claims.
[0038] (Air flow inside a control panel installed in a machine room) Next, with reference to FIGS. 4 and 5, the flow of air inside the control panel 100 installed in the machine room 230 according to this embodiment will be described.
[0039] As shown in FIG. 5, the control panel 100 has a control device 90 disposed therein for controlling the elevator 200. The control device 90 includes an inverter unit 91, a breaker 94, an operating unit 95, and a battery 96. The inverter unit 91 includes an inverter circuit (not shown) therein. The inverter unit 91 also includes a cooling fan 92 and cooling fins 93. A plurality of breakers 94, batteries 96, and cooling fins 93 are provided. In FIG. 5(a), the front member 10 is made transparent to facilitate the explanation of the air flow inside the control panel 100. In FIG. 5(b), the right side member 20 is made transparent to facilitate the explanation of the air flow inside the control panel 100.
[0040] The cooling fan 92 is a fan that moves air. In this embodiment, the cooling fan 92 moves air vertically upward (in the Z1 direction). The air moved by the cooling fan 92 is introduced through the right-side air intake port 20i and the left-side air intake port 30i. The air introduced through the right-side air intake port 20i and the left-side air intake port 30i passes through a first air guide path 150, which includes a fin ventilation path 151 that passes through the cooling fins 93, and is then discharged through the top-surface exhaust port 50i. The cooling fins 93 are fins that are provided with a plurality of plate-shaped members that extend in a direction perpendicular to the left-right direction (X-axis direction) when the control panel 100 is viewed from the front, and the fin ventilation path 151 is the space between the plurality of fins. Two cooling fins 93 are provided spaced apart from each other in the vertical direction (Z direction), and the cooling fin 93 on the vertically upper side (Z1 side) has a longer vertical length.
[0041] In this embodiment, the right side air intake 20i and the left side air intake 30i are provided below (in the Z2 direction) the inverter unit 91 in the vertical direction (Z direction). The inverter unit 91 is cooled by air passing through the first air guide duct 150. As described above, the rear air intake 40i is blocked by the machine room installation surface 231 (see FIG. 4), and therefore hardly any air can be introduced into it. In other words, in this embodiment, when the control panel 100 is installed in the machine room 230, air is introduced from both side surfaces (X1 side and X2 side) and exhausted from the top surface (Z1 side).
[0042] In this embodiment, within the control panel 100, among the areas of the cross sections along a direction perpendicular to the flow direction of the air introduced from the right side air intake port 20i and the left side air intake port 30i of the first air guide passage 150, the cross section of the fin air passage 151 has the smallest area. The cross sections of the two fin air passages 151 are equal to each other. In this embodiment, the combined area of the right side air intake port 20i and the left side air intake port 30i is equal to or greater than the cross section of the fin air passage 151. The fin air passage 151 is an example of the "air passage" defined in the claims.
[0043] The breaker 94 is a molded case circuit breaker that can automatically shut off an electric circuit in the event of an abnormal accident such as a short circuit or an overload current. The operation unit 95 includes a switch and is configured to allow some of the operations required to control the elevator 200 to be performed manually or automatically. A shielding plate 97 is disposed vertically below the operation unit 95 (in the Z2 direction). The shielding plate 97 is a flat member extending in a direction perpendicular to the vertical direction (the Z direction). The shielding plate 97 separates the spaces above (in the Z1 direction) and below (in the Z2 direction) the shielding plate 97 while maintaining partial communication between them. The battery 96 is, for example, a battery that supplies power to other devices in the control device 90 in the event of a power outage. Since the battery 96 may emit corrosive gases, in order to prevent the released corrosive gases from damaging other devices in the control device 90, a shielding plate 97 separates the space in which the battery 96 is located from the space in which the other devices in the control device 90 are located while maintaining partial communication between them, thereby actively suppressing the movement of air.
[0044] The rear ventilation opening 41i is provided below (Z2 direction) the shielding plate 97 in the vertical direction (Z direction), and ventilates the space vertically below (Z2 direction) the shielding plate 97. In other words, the rear ventilation opening 41i ventilates the space in which the battery 96 is disposed. Furthermore, because the area of the rear ventilation opening 41i is smaller than the area of the cross section of the fin ventilation passage 151 and because of the presence of the shielding plate 97, air is hardly actively introduced through the rear ventilation opening 41i due to the air flow caused by the cooling fan 92.
[0045] In this embodiment, the battery 96 is disposed below (in the Z2 direction) the right side surface air intake 20i and the left side surface air intake 30i in the vertical direction (Z direction). Air heated by the battery 96 rises vertically upward (in the Z1 direction) along the outward circulation path 160. The air that reaches the lower ends (ends on the Z2 side) of the right side surface air intake 20i and the left side surface air intake 30i in the vertical direction is cooled by air (outside air) introduced from the right side surface air intake 20i and the left side surface air intake 30i, and descends vertically downward (in the Z2 direction) along the return circulation path 161. As a result, the air heated by the battery 96 repeatedly rises and descends along the outward circulation path 160 and the return circulation path 161. The rising and descending of the air generates air convection, which cools the breaker 94, the operating unit 95, and the battery 96.
[0046] Here, the outward circulation path 160 is a space (passage) through which air heated by the battery 96 rises inside the control panel 100. The return circulation path 161 is a space (passage) through which the air that has risen along the outward circulation path 160 descends toward the battery 96 when cooled.
[0047] The air passing through first air guide path 150 hardly mixes with the air passing through outward circulation path 160 and return circulation path 161. Therefore, even if the air passing through outward circulation path 160 and return circulation path 161 contains corrosive gas released from battery 96, the air passing through first air guide path 150 hardly contains any corrosive gas, and therefore inverter unit 91 will not be damaged by the corrosive gas released from battery 96.
[0048] As described above, the inverter unit 91, which has the highest cooling priority among the control devices 90, is directly cooled by the air introduced by the cooling fan 92, and the control devices 90 other than 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. In this embodiment, the right side air intake 20i and the left side air intake 30i have an area capable of introducing an amount of air sufficient to cool the entire control device 90. The air introduced from the right side air intake 20i and the left side air intake 30i cools not only the control device 90 but also the interior of the control panel 100 including the control device 90. In this embodiment, the right side air intake 20i and the left side air intake 30i have an area capable of introducing an amount of air sufficient to cool the interior of the control panel 100.
[0049] (Configuration of control panel when installed inside the elevator shaft) Next, the configuration of the control panel 100 when installed in the hoistway 220 according to this embodiment will be described with reference to FIGS.
[0050] As shown in FIGS. 6 and 7, the control panel 100 includes a front member 10, a right side member 20, a left side member 30, a rear member 40, a top member 50, an air channel 70, a second bottom member 80, and control equipment 90 (see FIG. 9). That is, the control panel 100 when installed in the machine room 230 and the control panel 100 when installed in the elevator shaft 220 share the front member 10, right side member 20, left side member 30, rear member 40, and top member 50. Note that components common to the control panel 100 when installed in the machine room 230 are denoted by the same reference numerals, and redundant description will be omitted. Note that the front member 10, right side member 20, left side member 30, rear member 40, top member 50, air channel 70, and second bottom member 80 are examples of the "housing" in the claims.
[0051] 6 and 7, the air tunnel 70 is provided vertically above (on the Z1 side of) the top surface member 50. The surface of the air tunnel 70 that faces the top surface member 50 is open, and the five surfaces other than the surface that faces the top surface member 50 are formed from flat metal sheeting. The air tunnel 70 includes an air tunnel right side exhaust port 70i, an air tunnel left side exhaust port 71i, and an air tunnel rear side exhaust port 72i, and is provided with an air tunnel left side side wiring hole cover 70g and an air tunnel rear side wiring hole cover 71g.
[0052] The wind tunnel right side exhaust port 70i is provided on the right side (X1 side) of the wind tunnel section 70. The wind tunnel left side exhaust port 71i is provided on the left side (X2 side) of the wind tunnel section 70. The wind tunnel rear side exhaust port 72i is provided on the rear side (Y1 side) of the wind tunnel section 70. 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 exhaust ports that discharge air discharged from the top surface exhaust port 50i to the outside of the control panel 100.
[0053] In this embodiment, the air tunnel 70 is disposed so as to cover the top surface exhaust port 50i, thereby changing the flow direction of the air discharged from the top surface exhaust port 50i. The air flow inside the air tunnel 70 will be described later. In addition, in this embodiment, the air tunnel 70 does not have an exhaust port (opening) on the top surface side (Z1 side). This makes it possible to prevent water droplets and dust caused by condensation falling from above in the vertical direction (Z1 direction) from entering the interior of the control panel 100. Furthermore, in this embodiment, the air tunnel 70 is disposed so as to overlap with the top surface member 50 when viewed from above in the vertical direction (Z1 direction), thereby making it possible to effectively prevent water droplets and dust caused by condensation falling from above in the vertical direction (Z1 direction) from entering the interior of the control panel 100.
[0054] 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 multiple 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 openings provided on the left side and rear of the wind tunnel for passing wiring and the like. The wind tunnel left side wiring hole cover 70g and the wind tunnel rear side wiring hole cover 71g are, for example, grommets. 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 "second exhaust ports" in the claims.
[0055] The second bottom surface member 80 is provided with four openings 80n for inserting fixing members (not shown) that fix the control panel 100 to a shaft installation surface 221 (see FIG. 8) on which the control panel 100 is installed.
[0056] That is, compared to the control panel 100 installed in the machine room 230, the control panel 100 installed in the hoistway 220 has an air tunnel section 70 added thereto, and the first bottom member 60 is changed to a second bottom 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 to the control panel 100 installed in the machine room 230 and the control panel 100 installed in the hoistway 220. In addition, air intakes (right side air intake 20i, left side air intake 30i, and rear air intake 40i) and wiring holes are provided at common positions between the control panel 100 when installed in the machine room 230 and the control panel 100 when installed in the hoistway 220.
[0057] The front member 10, the right side member 20, the left side member 30, the rear member 40, the top member 50, the air channel 70, and the second bottom member 80 are each separate sheet metal members. In addition, in this embodiment, the right side air intake port 20i and the left side air intake port 30i are provided on different sides of the housing of the control panel 100 that extends in the vertical direction (Z direction), and the rear air intake port 40i is provided on the rear side of the housing of the control panel 100 that extends in the vertical direction (Z direction). In other words, in this embodiment, the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i are provided on different sides of the side, front (front face), and rear face of the housing of the control panel 100 that extend in the vertical direction (Z direction).
[0058] (Condition of the control panel installed inside the elevator shaft) Next, the state of the control panel 100 installed in the hoistway 220 according to this embodiment will be described with reference to FIGS.
[0059] As shown in FIG. 8, when the control panel 100 is installed in the hoistway 220, it is installed on a hoistway installation surface 221 (hatched portion) in the hoistway 220. At that time, the control panel 100 is installed by inserting a fixing member (not shown) into an opening 80n (see FIG. 7) provided in the second bottom surface member 80 and fixing the hoistway installation surface 221 and the control panel 100. The back side (Y1 side) and top side (Z1 side) of the control panel 100 installed in the hoistway 220 face the hoistway 220, and the front side (Y2 side) faces the elevator hall 240. The elevator hall 240 is a space in a building or the like in which the elevator 200 is installed where elevator users get on and off the elevator. Furthermore, the side surfaces (X1 side and X2 side) of the control panel 100 installed in the hoistway 220 face the structure 250 between the hoistway 220 and the elevator hall 240. For convenience of explanation, the end face of the structure 250 on the vertically upper side (Z1 side) is visible in Fig. 8, but in reality, the structure 250 extends in the vertical direction (Z direction) up to the end of the hoistway 220 on the vertically upper side (Z1 side).
[0060] In this embodiment, when the control panel 100 is installed in the hoistway 220, the right side air intake 20i (see FIG. 7) and the left side air intake 30i (see FIG. 7) are adjacent to a structure 250, which acts as an obstacle, reducing their ability to introduce air to cool the interior of the control panel 100 including the control device 90 (see FIG. 9). This makes it almost impossible for them to introduce air to cool the interior of the control panel 100 including the control device 90. On the other hand, the rear air intake 40i (see FIG. 7) is not adjacent to an obstacle, so its ability to introduce air to cool the interior of the control panel 100 including the control device 90 is not reduced, and it is possible for it to introduce an amount of air sufficient to cool the interior of the control panel 100 including the control device 90. In this embodiment, the area of the rear air intake 40i is an area sufficient to introduce an amount of air sufficient to cool the interior of the control panel 100 including the control device 90. The right side air intake port 20i and the left side air intake port 30i are examples of the "first air intake section" or "second air intake section" in the claims. The rear air intake port 40i is also an example of the "first air intake section" or "second air intake section" in the claims.
[0061] Furthermore, in this embodiment, when the control panel 100 is installed in the elevator shaft 220, the wind tunnel right side exhaust port 70i and the wind tunnel left side exhaust port 71i (see FIG. 7) are adjacent to a structure 250, which acts as an obstacle, reducing their ability to exhaust air from within the control panel 100, and therefore are unable to exhaust much air from within the control panel 100. On the other hand, the wind tunnel rear surface exhaust port 72i (see FIG. 7) has no adjacent obstacles, so its ability to exhaust air from within the control panel 100 is not reduced, and it can exhaust to the outside of the control panel 100 an amount of air that is sufficient to cool the inside of the control panel 100, including the control equipment 90 (see FIG. 9) installed in the control panel 100.
[0062] (Air flow inside the control panel installed in the elevator shaft) Next, the air flow inside the control panel 100 installed in the elevator shaft 220 according to this embodiment will be described with reference to Figures 8 and 9. Note that the same components as those in the control panel 100 installed in the machine room 230 are denoted by the same reference numerals, and duplicated explanations will be omitted.
[0063] 9(a), the front side (Y2 side) of the front member 10 and the air duct 70 are made transparent to illustrate the air flow inside the control panel 100. Also, FIG. 9(b) shows the right side member 20 and the right side (X1 side) of the air duct 70 made transparent to illustrate the air flow inside the control panel 100.
[0064] As shown in FIG. 9 , air circulated by the cooling fan 92 is introduced through the rear air intake port 40i. The air introduced through the rear air intake port 40i passes through a second air guide path 152, which includes a fin air passage 151 passing through the cooling fins 93, and is then discharged through the top exhaust port 50i. The air discharged through the top exhaust port 50i passes through the air tunnel 70 and is then discharged through the air tunnel rear exhaust port 72i. In this embodiment, the air tunnel 70 is disposed so as to cover the top exhaust port 50i, thereby changing the flow direction of the air discharged through the top exhaust port 50i. Specifically, in this embodiment, the air tunnel 70 is disposed so as to cover the top exhaust port 50i, thereby changing the flow direction of the air discharged through the top exhaust port 50i from a vertically upward direction (Z1 direction) to a direction from the front to the rear of the control panel 100 (Y1 direction).
[0065] In this embodiment, the rear air intake 40i is provided below (in the Z2 direction) the inverter unit 91 in the vertical direction (Z direction). The inverter unit 91 is cooled by air passing through the second air guide duct 152. At this time, as described above, the right side air intake 20i and the left side air intake 30i are blocked by the structure 250 (see FIG. 8 ), and therefore almost no air can be introduced. In other words, in this embodiment, when the control panel 100 is installed in the elevator shaft 220, air is introduced from the rear side (Y1 side) and air is exhausted from the rear side (Y1 side).
[0066] In this embodiment, within the control panel 100, of the areas of the cross sections of the second air guide passage 152 along a direction perpendicular to the flow direction of the air introduced from the rear air intake port 40i, the cross section of the fin air passage 151 has the smallest area. Here, the cross sections of the multiple fin air passages 151 are equal to each other. In this embodiment, the area of the rear air intake port 40i is equal to or larger than the cross section of the fin air passage 151. The fin air passage 151 is an example of the "air passage" in the claims.
[0067] In this embodiment, the battery 96 is disposed vertically (in the Z direction) below the rear air intake 40i (in the Z2 direction). The air flowing vertically below the rear air intake 40i (in the Z2 direction) is similar to that in the case of installation in the machine room 230, in that it convects by repeatedly ascending and descending. However, when the control panel 100 is installed in the elevator shaft 220, the right side air intake 20i and the left side air intake 30i are unable to introduce much air. Therefore, the air that rises vertically upward (in the Z1 direction) along the outward circulation path 160 is cooled by the air (outside air) introduced through the rear air intake 40i, and then descends vertically downward (in the Z2 direction) along the return circulation path 161. Here, the air passing through the second air guide path 152 and the air passing through the outward circulation path 160 and the return circulation path 161 hardly mix with each other. Therefore, even if the air passing through the forward circulation path 160 and the return circulation path 161 contains corrosive gases released from the battery 96, the air passing through the second air guide path 152 rarely contains corrosive gases, and therefore the inverter unit 91 will not be damaged by the corrosive gases released from the battery 96.
[0068] As described above, the inverter unit 91, which has the highest cooling priority among the control devices 90, is directly cooled by the air introduced by the cooling fan 92, and the control devices 90 other than 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. In this embodiment, the rear air intake 40i has an area capable of introducing an amount of air sufficient to cool the entire control device 90. The air introduced from the rear air intake 40i cools not only the control device 90 but also the inside of the control panel 100 including the control device 90. In this embodiment, the rear air intake 40i has an area capable of introducing an amount of air sufficient to cool the inside of the control panel 100.
[0069] (Effects of this embodiment) Next, the effects of this embodiment will be described.
[0070] In this embodiment, as described above, the housing includes, in the machine room 230, right side air intake port 20i and left side air intake port 30i, each having an area large enough to introduce a quantity of air sufficient to cool the interior of the housing, and, in the hoistway 220, rear air intake port 40i, each having an area large enough to introduce a quantity of air sufficient to cool the interior of the housing. This eliminates the need to change the position of the air intake port (design it individually) for at least two different installation environments, namely, at least the machine room 230 and the hoistway 220. As a result, it is possible to reduce the effort and time required to design the structure of the housing required for each installation environment.
[0071] Furthermore, in this embodiment, as described above, the housing includes a ventilation passage through which air introduced from at least one of right side surface intake port 20i, left side surface intake port 30i, and rear surface intake port 40i flows, and the areas of right side surface intake port 20i, left side surface intake port 30i, and rear surface intake port 40i are equal to or greater than the cross-sectional area of the ventilation passage. This allows right side surface intake port 20i, left side surface intake port 30i, and rear surface intake port 40i to have relatively large areas, making it possible to easily introduce an amount of air sufficient to sufficiently cool the control devices regardless of the installation environment.
[0072] In this embodiment, as described above, the housing has a rectangular parallelepiped shape that is elongated in the vertical direction, and the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i are provided on different surfaces of the side, front, and rear of the housing that extend vertically. This reduces the effort and time required to design the components that make up the side, front, and rear surfaces of the housing, which have relatively large areas. Furthermore, the number of types of components of the housing can be reduced, thereby improving productivity.
[0073] Furthermore, in this embodiment, as described above, the housing includes a top exhaust port 50i that is provided on the top surface of the housing and that exhausts air to the outside of the housing, and also includes an air channel 70 that is arranged to cover the top exhaust port 50i and change the flow direction of the air exhausted from the top exhaust port 50i. This makes it easier to change the flow direction of the air exhausted from the top exhaust port 50i for each installation environment, compared to a case that does not include the air channel 70. As a result, it is no longer necessary to design individual exhaust ports for each installation environment, and the effort and time required to design the exhaust ports, which are part of the housing structure required for each installation environment, can be easily reduced.
[0074] Furthermore, in this embodiment, as described above, the air tunnel 70 is provided with the air tunnel right side exhaust port 70i, the air tunnel left side exhaust port 71i, and the air tunnel rear exhaust port 72i, which exhaust air discharged from the top surface exhaust port 50i, on the rear and side surfaces of the air tunnel 70, and no exhaust port is provided on the top surface of the air tunnel 70. As a result, no exhaust port is provided on the top surface of the control panel 100, and therefore, damage to the control device 90 caused by water droplets due to condensation falling from above and dust entering the interior can be suppressed.
[0075] Furthermore, in this embodiment, as described above, the housing includes top exhaust port 50i that is provided on the top surface of the housing and that discharges air to the outside of the housing, control device 90 includes inverter unit 91 that is provided with cooling fan 92 above in the vertical direction, and right side surface air intake port 20i, left side surface air intake port 30i, and rear surface air intake port 40i are provided in positions vertically below inverter unit 91. As a result, regardless of the installation environment, inverter unit 91, which has a relatively high priority for cooling, can be directly cooled by air introduced from at least one of right side surface air intake port 20i, left side surface air intake port 30i, and rear surface air intake port 40i.
[0076] Furthermore, in this embodiment, as described above, the control device 90 further includes a battery 96, which is disposed vertically below the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i. As a result, the air heated by the battery 96 rises to the positions of the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i, comes into contact with air introduced from at least one of the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i, is cooled, and then descends to the position of the battery 96. As a result, in addition to the control device 90 (inverter unit 91) located above the right side air intake 20i, left side air intake 30i, and rear air intake 40i, the control device 90 located below the right side air intake 20i, left side air intake 30i, and rear air intake 40i is also cooled by the air convection between the battery 96 and the right side air intake 20i, left side air intake 30i, and rear air intake 40i, thereby preventing damage to the inverter unit 91 due to corrosive gases that may be released from the battery 96 and allowing the entire control device 90 to be cooled by air introduced from at least one of the right side air intake 20i, left side air intake 30i, and rear air intake 40i.
[0077] Furthermore, in this embodiment, as described above, the control device 90 includes the inverter unit 91 having the cooling fins 93, and the cross-sectional area of the ventilation path is the ventilation area of the cooling fins 93. This increases the amount of air passing through the cooling fins 93 compared to when the areas of the right side surface air intake 20i and the left side surface air intake 30i and the rear surface air intake 40i are smaller than the ventilation area of the cooling fins 93. As a result, regardless of the installation environment, the inverter unit 91, which has a relatively high priority for cooling, can be efficiently cooled by air introduced from at least one of the right side surface air intake 20i, the left side surface air intake 30i, and the rear surface air intake 40i.
[0078] Furthermore, in this embodiment, as described above, the first installation environment is either the inside of the elevator hoistway 220 or the inside of the machine room 230 installed separately from the elevator hoistway 220, and the second installation environment is the other of the inside of the elevator hoistway 220 or the inside of the machine room 230 installed separately from the elevator hoistway 220. This makes it possible to reduce the effort and time required to design the structure of the housing required in the elevator hoistway 220 and the machine room 230 installed separately from the elevator hoistway 220, where the control panel 100 is likely to be installed. As a result, it is possible to efficiently reduce the effort and time required to design the structure of the housing required for each installation environment.
[0079] [Variations] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims rather than the above description of the embodiments, and further includes all modifications (variations) within the meaning and scope of the claims.
[0080] For example, in the present embodiment, the areas of right side surface intake port 20i, left side surface intake port 30i, and rear surface intake port 40i are equal to or larger than the cross-sectional area of fin ventilation passage 151. However, the present invention is not limited to this. For example, the areas of right side surface intake port 20i, left side surface intake port 30i, and rear surface intake port 40i may be smaller than the cross-sectional area of fin ventilation passage 151.
[0081] In addition, in this embodiment, the housing has a rectangular parallelepiped shape that is long in the vertical direction, and the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i are provided on different surfaces among the side, front, and rear surfaces of the housing that extend in the vertical direction, but the present invention is not limited to this. For example, the housing may have a rectangular parallelepiped shape that is long in the horizontal direction, and the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i may be provided on the same surface among the side, front, and rear surfaces of the housing that extend in the vertical direction.
[0082] In addition, in the present embodiment, the housing of the control panel 100 includes the air channel 70 that is arranged to cover the top surface exhaust port 50i and changes the flow direction of the air discharged from the top surface exhaust port 50i. However, the present invention is not limited to this. For example, the housing of the control panel 100 does not have to include the air channel 70.
[0083] In addition, in the present embodiment, an example has been shown in which the air tunnel 70 does not have an exhaust port on the top surface of the air tunnel 70, but the present invention is not limited to this. For example, the air tunnel 70 may be configured to have an exhaust port on the top surface of the air tunnel 70, and a cover may be provided on the top as necessary to prevent water droplets and dust from entering.
[0084] In addition, in the present embodiment, the right side surface air intake port 20i, the left side surface air intake port 30i, and the rear surface air intake port 40i are provided below the inverter unit 91 in the vertical direction, but the present invention is not limited to this. For example, the right side surface air intake port 20i, the left side surface air intake port 30i, and the rear surface air intake port 40i may be provided above the inverter unit 91 in the vertical direction.
[0085] In addition, in the present embodiment, the battery 96 is disposed vertically below the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i, but the present invention is not limited to this. For example, the battery 96 may be disposed vertically above the right side air intake port 20i, the left side air intake port 30i, and the rear air intake port 40i.
[0086] Furthermore, in the present embodiment, an example has been shown in which the control panel 100 is installed in the elevator hoistway 220 and in the machine room 230 installed separately from the elevator hoistway 220, but the present invention is not limited to this. For example, the control panel 100 may be installed in an installation environment other than the elevator hoistway 220 and in the machine room 230 installed separately from the elevator hoistway 220.
[0087] Furthermore, in the present embodiment, an example has been shown in which the control panel 100 does not include the air tunnel unit 70 when installed in the machine room 230, but the present invention is not limited to this. For example, the control panel 100 may include the air tunnel unit 70 when installed in the machine room 230. In this case, the air tunnel rear exhaust port 72i is adjacent to the machine room installation surface 231, which acts as an obstacle, reducing the function of exhausting air from inside the control panel 100 and making it almost impossible to exhaust air from inside the control panel 100. Therefore, air is exhausted from the air tunnel right side exhaust port 70i and the air tunnel left side exhaust port 71i.
[0088] In addition, in the present embodiment, an example has been shown in which the housing of the control panel 100 is formed from sheet metal, but the present invention is not limited to this. For example, the housing of the control panel 100 may be formed from a material other than metal, such as resin.
[0089] In addition, in this embodiment, the front member 10 includes the upper front member 10a and the lower front member 10b, but the present invention is not limited to this. For example, the front member 10 may be a single member.
[0090] In addition, in this embodiment, when the control panel 100 is installed in the machine room 230, the front member 10, right side member 20, left side member 30, rear member 40, top member 50 and first bottom member 60 are each separate sheet metal members, and when the control panel 100 is installed in the elevator shaft 220, the front member 10, right side member 20, left side member 30, rear member 40, top member 50, air tunnel section 70 and second bottom member 80 are each separate sheet metal members, but the present invention is not limited to this. For example, when the control panel 100 is installed in the machine room 230, at least two of the front member 10, right side member 20, left side member 30, rear member 40, top member 50 and first bottom member 60 may be the same sheet metal member, and when the control panel 100 is installed in the elevator shaft 220, at least two of the front member 10, right side member 20, left side member 30, rear member 40, top member 50, air tunnel section 70 and second bottom member 80 may be the same sheet metal member.
[0091] In addition, in the present embodiment, the right side air intake 20i, the left side air intake 30i, the rear air intake 40i, the rear ventilation port 41i, the wind tunnel right side exhaust port 70i, the wind tunnel left side exhaust port 71i, and the wind tunnel rear exhaust port 72i each include a plurality of openings, but the present invention is not limited to this.
