[Brief explanation of the drawings]

[0006] [Figure 1] Schematic diagram of an elevator according to an embodiment. [Figure 2] FIG. 10 is a front view of the power conversion device according to the embodiment. [Figure 3] FIG. 10 is a side view of the power conversion device according to the embodiment. [Figure 4] FIG. 2 is a perspective view of the power conversion device according to the embodiment; [Figure 5] FIG. 2 is a perspective view of the power conversion device according to the embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0007] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0008] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0009] An embodiment of an elevator, an elevator control panel, and a power conversion device will be described below with reference to Figures 1 to 5. Note that the following embodiment is provided as an example to help understand the configurations of the elevator, elevator control panel, and power conversion device, and does not limit the configurations of the elevator, elevator control panel, and power conversion device.

[0010] 1, the elevator 1 may include, for example, a car 1a for people (passengers) to ride in, a car drive unit 2 that drives the car 1a, a car rail 1b that guides the car 1a, and a processing unit 1c that controls each part of the elevator 1. The drive system of the car drive unit 2 is not particularly limited.

[0011] For example, as in this embodiment, the elevator 1 may be configured to include a car rope 1d having a first end connected to the car 1a, a counterweight 1e connected to a second end of the car rope 1d, and a counterweight rail 1f that guides the counterweight 1e, and the car drive unit 2 may be configured to include a sheave 2a around which the car rope 1d is wound, and a drive source 2b (e.g., a motor) that rotates the sheave 2a.

[0012] That is, the car drive unit 2 may be a hoist and the elevator 1 may be a rope-type drive system. However, the present invention is not limited to such a configuration, and may be configured, for example, such that the car drive unit 2 is a hydraulic device and the elevator 1 is a hydraulic drive system, or such that the car drive unit 2 is a linear motor and the elevator 1 is a linear motor-type drive system.

[0013] In addition, in this embodiment, the first end of the car rope 1d is connected to the car 1a, and the second end of the car rope 1d is connected to the counterweight 1e, but the present invention is not limited to this configuration. For example, a configuration is also possible in which both ends of the car rope 1d are fixed to the upper or lower part of the hoistway X2, and the car rope 1d is wound around the sheaves of the car 1a and the counterweight 1e, respectively, thereby connecting the car rope 1d to the car 1a and the counterweight 1e, respectively.

[0014] Furthermore, the elevator 1 according to this embodiment is configured such that the hoisting machine, which is the car drive unit 2, is disposed inside the machine room X1, but is not limited to such a configuration. For example, the elevator 1 may be configured such that the machine room X1 is not provided and the hoisting machine is disposed inside the hoistway X2.

[0015] The processing unit 1c includes an elevator control panel (hereinafter also simply referred to as "control panel") 3 arranged inside the machine room X1. The control panel 3 includes a box-shaped panel main body 4 arranged inside the machine room X1, and a power converter 5 removably attached to the panel main body 4 inside the panel main body 4 and supplying power for running the car 1a. The panel main body 4 may be configured so that the inside can be opened, for example, by opening a door or removing a cover.

[0016] In the elevator 1 according to this embodiment, the control panel 3 (panel body 4) is arranged inside the machine room X1, but the configuration is not limited to this. For example, the machine room X1 may not be provided, and the control panel 3 (panel body 4) may be arranged inside the hoistway X2.

[0017] The power conversion device 5 may be, for example, an inverter device or may be, for example, a converter device. The inverter device may be configured to change the traveling speed of the car 1a by changing the frequency of the power for running the car 1a, specifically, the power supplied to the car drive unit 2 (hoisting device).

[0018] 2 to 5, the power converter 5 includes an electric component 6 through which a current flows, a housing 7 in which the electric component 6 is disposed, and grips 11 and 12 to be held. The power converter 5 may be removably attached to the panel body 4 by attachment means 3a (for example, a screw member) as in this embodiment.

[0019] Although not particularly limited, the weight of the power conversion device 5 may be, for example, 10 kg or more, or may be, for example, 20 kg or more. Furthermore, although not particularly limited, the weight of the power conversion device 5 may be, for example, 50 kg or less, or may be, for example, 40 kg or less.

[0020] In this specification, the directions D1 to D3 in the power conversion device 5 are the directions D1 to D3 when a person facing the power conversion device 5 looks at the power conversion device 5 with the power conversion device 5 attached to the panel main body 4. Therefore, the first direction (first lateral direction) D1 is also called the front-to-back direction D1, the second direction (second lateral direction) D2 is also called the left-to-right direction D2, and the third direction D3 is also called the up-down direction D3.

[0021] Of the first directions D1, the arrow direction in each drawing is the forward direction (toward the user), and the direction opposite to the arrow direction in each drawing is the backward direction. Of the second directions D2, the arrow direction in each drawing is the leftward direction, and the direction opposite to the arrow direction in each drawing is the rightward direction. Of the third directions, the arrow direction in each drawing is the upward direction, and the direction opposite to the arrow direction in each drawing is the downward direction. Of course, when the power conversion device 5 is removed from the panel body 4, the directions D1 to D3 may be different.

[0022] The housing 7 includes a pair of side surfaces 7a, 7b that are separated in the left-right direction D2, and a base surface portion 7c that connects the pair of side surfaces 7a, 7b. Also, for example, as in this embodiment, the housing 7 may include a cover surface portion 7d that covers the interior from the front, and the cover surface portion 7d may be removably attached to the side surfaces 7a, 7b by attachment means (for example, bolts and nuts) that are not shown.

[0023] The base surface portion 7c may have, for example, an attachment hole 7e into which the attachment means 3a (for example, a screw member) is inserted, as in the present embodiment, so that the base surface portion 7c is detachably attached to the board body 4 by the attachment means 3a.

[0024] In addition, the upper end of the base surface portion 7c may be located higher than the upper end of the cover surface portion 7d, as in this embodiment, so that the housing 7 has an upper opening portion 7f located at the top and open at the top and front.

[0025] In addition, the lower end of the base surface portion 7c may be located lower than the lower end of the cover surface portion 7d, as in this embodiment, so that the housing 7 has a lower open portion 7g located at the bottom and open downward and forward.

[0026] The electric component 6 may include, for example, a blower fan 6a that supplies and exhausts air inside the power converter 5, and a first terminal block 6b and a second terminal block 6c to which electric wires (not shown) from the outside are connected. Note that the first terminal block 6b may be disposed below and behind the second terminal block 6c, for example, as in this embodiment.

[0027] Although not particularly limited, in this embodiment, the blower fan 6a is the uppermost component 6a of the electrical components 6 that is arranged at the uppermost position inside the housing 7. The uppermost component 6a may be arranged inside the upper opening 7f of the housing 7, for example, as in this embodiment.

[0028] Although not particularly limited, in this embodiment, the first terminal block 6b is the lowest component 6b of the electrical components 6 that is arranged at the lowest position inside the housing 7. The lowest component 6b may be arranged inside the bottom opening 7g of the housing 7, for example, as in this embodiment.

[0029] The handles 11, 12 include an upper handle 11 disposed inside the upper open portion 7f of the housing 7 and a lower handle 12 disposed inside the lower open portion 7g of the housing 7. As a result, the upper handle 11 is exposed from above and the front, and the lower handle 12 is exposed from below and the front. Therefore, the upper handle 11 can be grasped from above and the front of the housing 7, and the lower handle 12 can be grasped from below and the front of the housing 7.

[0030] Therefore, for example, when removing the power conversion device 5 from the panel main body 4, the elevator maintenance personnel can safely and easily hold the power conversion device 5. Furthermore, for example, when reattaching the removed power conversion device 5 to the panel main body 4 or when attaching a new power conversion device 5 to the panel main body 4, the elevator maintenance personnel can safely and easily hold the power conversion device 5.

[0031] Furthermore, by gripping the upper handle 11 and the lower handle 12, the upper and lower parts of the power conversion device 5 can be gripped. Therefore, for example, by gripping the lower handle 12, the power conversion device 5 can be supported from below, and by gripping the upper handle 11, the power conversion device 5 can be stably gripped.

[0032] The upper handle 11 and the lower handle 12 are spaced apart in both the up-down direction D3 and the front-to-rear direction D1. For example, the upper handle 11 may be disposed above and forward of the lower handle 12, as in this embodiment. The center of gravity 5a of the power converter 5 in the up-down direction D3 is located between the upper handle 11 and the lower handle 12 in the up-down direction D3, and the center of gravity 5a of the power converter 5 in the front-to-rear direction D1 is located between the upper handle 11 and the lower handle 12 in the front-to-rear direction D1.

[0033] As a result, by gripping the upper handle 11 and the lower handle 12, the power conversion device 5 can be held at positions sandwiching the center of gravity 5a in the up-down direction D3 and the front-back direction D1 of the power conversion device 5. Therefore, for example, the power conversion device 5 can be held stably.

[0034] Each of the upper handle 11 and the lower handle 12 is disposed inside the housing 7. This makes it possible to prevent the size of the power conversion device 5 outside the housing 7 from increasing. Therefore, compared to a configuration in which the housing 7 is the same size and the handles 11 and 12 are disposed outside the housing 7, for example, it is possible to prevent the size of the power conversion device 5 from increasing.

[0035] Furthermore, the upper handle 11 is disposed below the upper end of the top component 6a. As a result, although the upper handle 11 is disposed inside the housing 7 (specifically, inside the upper open portion 7f), it is possible to prevent the distance between the upper end of the housing 7 and the upper end of the top component 6a from becoming too large.

[0036] Therefore, for example, compared to a configuration in which the electrical components 6 are arranged in the same manner and the upper handle 11 is arranged above the upper end of the top component 6a, it is possible to prevent the dimension of the housing 7 in the up-down direction D3 from increasing. Note that the upper handle 11 may overlap the top component 6a when viewed in the front-to-rear direction D1, as in this embodiment.

[0037] Moreover, lower handle 12 is disposed above the lower end of bottom component 6b. This prevents the distance between the lower end of housing 7 and the lower end of bottom component 6b from becoming too large, even though lower handle 12 is disposed inside housing 7 (specifically, inside lower open portion 7g).

[0038] Therefore, for example, compared to a configuration in which the electrical components 6 are arranged in the same manner and the lower handle 12 is arranged below the lower end of the lowest component 6b, it is possible to prevent the dimension of the housing 7 in the up-down direction D3 from increasing. Note that the lower handle 12 may overlap the lowest component 6b when viewed in the front-to-rear direction D1, as in this embodiment.

[0039] Furthermore, the upper handle 11 extends in the left-right direction D2 to connect the pair of side surface portions 7a, 7b, and the lower handle 12 extends in the left-right direction D2 to connect the pair of side surface portions 7a, 7b. As a result, the upper handle 11 and the lower handle 12 not only function as handles but also function to reinforce the housing 7. Note that the upper handle 11 and the lower handle 12 may be formed in a cylindrical shape, for example, as in this embodiment.

[0040] Furthermore, the electrical component 6 may include, for example, a first component 6d, a second component 6e, and a third component 6f, which are arranged below the upper handle 11, as in this embodiment. Although not particularly limited, for example, the first component 6d and the second component 6e may be low-voltage electrical components (for example, 24 V or less), and the third component 6f may be a high-voltage electrical component (for example, 100 V to 500 V).

[0041] The power converter 5 also includes an electric wire 8 that electrically connects the first component 6d and the second component 6e. The electric wire 8 is disposed inside the upper handle 11. As a result, the upper handle 11 not only functions as a handle but also functions to store the electric wire 8. Moreover, since the electric wire 8 is disposed away from the third component 6f, which is a high-voltage electrical component, it is possible to suppress, for example, electrical noise from being generated in signals flowing through the electric wire 8.

[0042] The lower handle 12 also supports the first terminal block 6b, which is the lowest component 6b. As a result, the lower handle 12 not only functions as a handle but also functions to support the electrical components 6. Note that the power conversion device 5 may also include, for example, a first support portion 9 that supports the first terminal block 6b and a second support portion 10 that supports the second terminal block 6c, as in this embodiment.

[0043] The first support part 9 may be configured to be fixed to the lower handle 12 and to fix the first terminal block 6b, as in this embodiment. The second support part 10 may be configured to be fixed to the housing 7 (specifically, the side surface parts 7a and 7b), as in this embodiment, and to fix the second terminal block 6c.

[0044] [1] As described above, the elevator control panel 3, as in this embodiment, A panel body 4 disposed inside the elevator shaft X2 or the machine room X1 (in this embodiment, the machine room X1); a power conversion device 5 that is removably attached to the board body 4 inside the board body 4 and supplies power for running the car 1a, The power conversion device 5 includes: Electrical components 6; a housing 7 in which the electrical component 6 is disposed; and grips 11 and 12 to be gripped, The handles 11 and 12 are disposed inside the housing 7 and are exposed. This configuration is preferred.

[0045] According to this configuration, the power conversion device 5 is provided with the handles 11, 12, and therefore the power conversion device 5 can be easily held by holding the handles 11, 12. Furthermore, because the handles 11, 12 are arranged inside the housing 7, it is possible to prevent the size of the power conversion device 5 outside the housing 7 from increasing, and further, because the handles 11, 12 are exposed, the handles 11, 12 can be held.

[0046] [2] In addition, in the elevator control panel 3 of [1] above, as in this embodiment, The housing 7 is An upper opening portion 7f disposed at the top and open at the top and front; a lower opening portion 7g disposed at the lower portion and open downward and forward; The handles 11 and 12 are an upper handle 11 disposed inside the upper opening 7f; A lower handle 12 is disposed inside the lower open portion 7g. This configuration is preferred.

[0047] According to this configuration, the upper open portion 7f is located at the top of the housing 7 and is open at the top and front, and the upper handle 11 is located inside the upper open portion 7f. This allows the upper handle 11 to be grasped from above and from the front of the housing 7.

[0048] The lower open portion 7g is disposed at the bottom of the housing 7 and is open downward and forward, and the lower handle 12 is disposed inside the lower open portion 7g. This allows the lower handle 12 to be grasped from below and from the front of the housing 7. The upper and lower portions of the power conversion device 5 can be grasped by grasping the upper handle 11 and the lower handle 12, respectively.

[0049] [3] In addition, in the elevator control panel 3 of [2] above, as in this embodiment, The upper handle 11 and the lower handle 12 are spaced apart in the up-down direction D3 and the front-rear direction D1, A center of gravity position 5a of the power conversion device 5 in the vertical direction D3 is a position between the upper handle 11 and the lower handle 12 in the vertical direction D3, The center of gravity 5a of the power conversion device 5 in the front-rear direction D1 is a position between the upper handle 11 and the lower handle 12 in the front-rear direction D1. This configuration is preferred.

[0050] With this configuration, the upper handle 11 and the lower handle 12 are spaced apart in both the up-down direction D3 and the front-back direction D1, and the center of gravity 5a of the power conversion device 5 is located between the upper handle 11 and the lower handle 12 in both the up-down direction D3 and the front-back direction D1. As a result, by gripping the upper handle 11 and the lower handle 12, the power conversion device 5 can be gripped at positions sandwiching the center of gravity 5a in both the up-down direction D3 and the front-back direction D1.

[0051] [4] In addition, in the elevator control panel 3 of the above [2] or [3], as in this embodiment, The housing 7 is A pair of side surface portions 7a, 7b separated in the left-right direction D2; a base surface portion 7c connecting the pair of side surface portions 7a, 7b, The upper handle 11 extends in the left-right direction D2 and connects the pair of side surface portions 7a, 7b. The lower handle 12 extends in the left-right direction D2 and connects the pair of side surface portions 7a, 7b. This configuration is preferred.

[0052] According to this configuration, the upper handle 11 and the lower handle 12 each extend in the left-right direction D2 and connect the pair of side surfaces 7a, 7b that are spaced apart in the left-right direction D2. This allows the upper handle 11 and the lower handle 12 to function not only as handles but also to reinforce the housing 7.

[0053] [5] In addition, in the elevator control panel 3 of any one of the above [2] to [4], as in this embodiment, The electrical component 6 is an uppermost part 6a disposed at the topmost position inside the housing 7; a bottom part (6b) disposed at the lowest position inside the housing (7), The upper handle 11 is disposed below the upper end of the top part 6a, The lower handle 12 is disposed above the lower end of the lowest part 6b. This configuration is preferred.

[0054] According to this configuration, the upper handle 11 is disposed below the upper end of the top component 6a, which is the electrical component 6 disposed at the topmost position inside the housing 7. As a result, although the upper handle 11 is disposed inside the housing 7, it is possible to prevent the distance between the top end of the housing 7 and the top end of the top component 6a from becoming too large.

[0055] Furthermore, lower handle 12 is disposed above the lower end of bottom component 6b, which is the electrical component 6 disposed lowest inside housing 7. This prevents the distance between the bottom end of housing 7 and the bottom end of bottom component 6b from becoming too large, even though lower handle 12 is disposed inside housing 7.

[0056] [6] In addition, in the elevator control panel 3 of any one of the above [2] to [5], as in this embodiment, The electrical component 6 includes a first component 6d and a second component 6e that are disposed below the upper handle 11, The power conversion device 5 includes an electric wire 8 that electrically connects the first component 6d and the second component 6e, The electric wire 8 is disposed inside the upper handle 11. The following configuration is preferred:

[0057] With this configuration, the electric wire 8 electrically connects the first component 6d and the second component 6e, which are located below the upper handle 11, and the electric wire 8 is located inside the upper handle 11. As a result, the upper handle 11 has not only a handle function but also a function for storing the electric wire 8.

[0058] [7] In addition, in the elevator control panel 3 of any one of the above [2] to [6], as in this embodiment, The electrical component 6 includes a bottom component 6b that is disposed at the bottommost position inside the housing 7, The lower handle 12 supports the bottom part 6b. This configuration is preferred.

[0059] According to this configuration, the lower handle 12 supports the lowest component 6b, which is the electrical component 6 arranged lowest inside the housing 7. As a result, the lower handle 12 has not only a function as a handle but also a function of supporting the electrical component 6.

[0060] [8] In addition, the elevator 1, as in this embodiment, Any one of the elevator control panels 3 described above in [1] to [7]; and a car 1a that runs using power supplied from the elevator control panel 3. This configuration is preferred.

[0061] With this configuration, the power converter 5 can be easily held.

[0062] [9] Furthermore, as in this embodiment, the power conversion device 5 Used in any one of the elevator control panels 3 of [1] to [7] above, This configuration is preferred.

[0063] With this configuration, the power converter 5 can be easily held.

[0064] The elevator 1, elevator control panel 3, and power conversion device 5 are not limited to the configurations of the above-described embodiment, and are not limited to the above-described effects. Furthermore, various modifications can be made to the elevator 1, elevator control panel 3, and power conversion device 5 without departing from the spirit of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations, methods, etc. according to the various modified examples described below and adopt them in the configurations, methods, etc. according to the above-described embodiment.

[0065] (A) The power converter 5 according to the above embodiment is configured to have two handles (upper handle 11 and lower handle 12). However, the power converter 5 is not limited to this configuration. The power converter 5 may be configured to have, for example, only one handle 11, 12, or may be configured to have, for example, three or more handles 11, 12.

[0066] (B) Furthermore, in the power converter 5 according to the above embodiment, the upper opening 7f of the housing 7 is open upward and forward, and the lower opening 7g of the housing 7 is open downward and forward. However, the power converter 5 is not limited to this configuration.

[0067] For example, the upper opening 7f of the housing 7 may be configured to be open only at either the top or the front, and the lower opening 7g of the housing 7 may be configured to be open only at either the bottom or the front.

[0068] (C) Furthermore, in the power converter 5 according to the above embodiment, the center of gravity 5a of the power converter 5 in the up-down direction D3 is a position between the upper handle 11 and the lower handle 12 in the up-down direction D3, and the center of gravity 5a of the power converter 5 in the front-rear direction D1 is a position between the upper handle 11 and the lower handle 12 in the front-rear direction D1. However, the power converter 5 is not limited to this configuration.

[0069] For example, the center of gravity 5a of the power conversion device 5 in the up-down direction D3 may be located at a position that is not between the upper handle 11 and the lower handle 12 in the up-down direction D3. Also, for example, the center of gravity 5a of the power conversion device 5 in the front-rear direction D1 may be located at a position that is not between the upper handle 11 and the lower handle 12 in the front-rear direction D1.

[0070] (E) In the power converter 5 according to the above embodiment, the upper handle 11 extends in the left-right direction D2 to connect the pair of side surfaces 7 a, 7 b, and the lower handle 12 extends in the left-right direction D2 to connect the pair of side surfaces 7 a, 7 b. However, the power converter 5 is not limited to this configuration.

[0071] The upper handle 11 may extend, for example, in the front-rear direction D1 or in the up-down direction D3. The upper handle 11 may also be spaced apart from at least one of the pair of side surface portions 7a, 7b.

[0072] The lower handle 12 may extend, for example, in the front-rear direction D1 or in the up-down direction D3. The lower handle 12 may also be spaced apart from at least one of the pair of side surface portions 7a, 7b.

[0075] (G) Furthermore, in the power converter 5 according to the above embodiment, the electric wires 8 are arranged inside the upper handle 11. However, the power converter 5 is not limited to such a configuration. For example, all the electric wires may be arranged outside the upper handle 11.

[0076] (H) In the power converter 5 according to the above embodiment, the lower handle 12 is configured to support the lowest component 6b. However, the power converter 5 is not limited to this configuration. For example, the lower handle 12 may be configured to be separated from all of the electrical components 6, i.e., not to support any of the electrical components 6.

[0077] (I) For example, the power conversion device 5 may be configured to include a display unit (for example, a nameplate) that indicates the handles 11, 12. With such a configuration, the presence and positions of the handles 11, 12 can be easily recognized.

[0078] (J) For example, the order of execution of each step, such as the operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, can be implemented in any order, as long as the result of a previous step is not used in a subsequent step. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the steps must be executed in that order. [Explanation of symbols]
