Detailed Description

Hereinafter, an industrial facility according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment.

Embodiment 1.

Fig. 1 is a diagram showing a configuration of an industrial apparatus according to embodiment 1 of the present invention. Fig. 2 is an exploded perspective view of the industrial equipment according to embodiment 1. The back surface of the industrial equipment 100 according to embodiment 1 is fixed to and supported by the support member 70. The support member 70 is attached to a wall or the like in a factory to fix the industrial equipment 100 at a predetermined position. Industrial equipment is often fixed and installed in a factory, which causes complicated maintenance of the industrial equipment.

The industrial device 100 includes a Circuit board having electronic components such as a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC) for a Specific Application, and a resistor or a capacitor mounted therein in a housing 21. Since the electronic components on the circuit board generate heat during operation, the electronic components are cooled by a fan described later. The circuit board is formed in a single piece or a plurality of pieces corresponding to the arrangement area inside the housing 21.

The housing 21 of the industrial equipment 100 has a fan unit housing portion 22 formed at a corner portion where surfaces of the front surface 21a and the lower surface 21b of the housing 21 meet each other. The fan unit 30 housed in the fan unit housing portion 22 operates as a part of the industrial equipment 100. As shown in fig. 2, the fan unit 30 is attachable to and detachable from the fan unit housing 22 from the front of the industrial equipment 100. In the fan unit 30, a fan 32 is housed inside a cylindrical housing 31 having an open upper surface and a lower surface. The fan unit 30 blows air sucked from the lower surface out of the upper surface, and sends an air flow generated by the fan 32 into the industrial equipment 100, thereby cooling the cooling target in the industrial equipment 100. Therefore, the industrial equipment 100 is supported by the support member 70 in a state where a gap for sucking air is secured below.

Further, although the housing 21 of the industrial equipment 100 is formed with the fan unit housing 22 at the corner where the front surface 21a and the lower surface 21b of the housing 21 meet each other, the fan unit housing 22 may be formed at the corner where the front surface 21a and the upper surface of the housing 21 meet each other. The housing 21 of the industrial equipment 100 may have the fan unit housing 22 formed at a corner where the surfaces of the side surface and the lower surface of the housing 21 meet, or the fan unit housing 22 may be formed at a corner where the surfaces of the side surface and the upper surface of the housing 21 meet. When the fan unit housing portion 22 is formed at a corner where the side surface and the lower surface of the housing 21 meet each other or at a corner where the side surface and the upper surface of the housing 21 meet each other, the fan unit 30 is attached to and detached from the fan unit housing portion 22 from the side of the industrial equipment 100.

In the following description, the front-rear direction refers to a direction along the Y axis in fig. 1, the left-right direction refers to a direction along the X axis in fig. 1, and the up-down direction refers to a direction along the Z axis in fig. 1. In addition, the + X direction is defined as left, the-X direction as right, the + Y direction as front, the-Y direction as rear, the + Z direction as up, and the-Z direction as down. The definitions of the front-back direction, the left-right direction, and the up-down direction in fig. 1 are also applicable to the industrial equipment 100 and the fan unit 30 in other drawings.

Fig. 3 is a perspective view of the fan unit of the industrial equipment according to embodiment 1, as viewed from diagonally front. Fig. 4 is an enlarged view of the left side surface of the fan unit of the industrial equipment according to embodiment 1. The housing 31 of the fan unit 30 has guide ribs 33 formed on the left and

right surfaces

31a and 31 b. Further, a fixing hook 34 is provided at an upper end portion of the front surface portion 31c of the housing portion 31 of the fan unit 30. The fixing hook 34 is provided with: a hook 341 that engages with an engagement wall 241, described later, formed above the fan unit housing portion 22 of the industrial equipment 100; and a grip portion 342 serving as a removal operation portion that receives an operation of removing the fan unit housing portion 22. Therefore, the fan unit 30 includes an operation portion on the front surface, which is the surface on the detachment direction side, for receiving an operation of detaching the fan unit from the fan unit housing portion 22. The fan unit 30 includes a removal operation portion, and thus the fan unit 30 can be easily removed from the fan unit housing portion 22.

The grip 342 protrudes upward from the front surface portion 31c and is gripped by a user during attachment/detachment operation of the fan unit 30. The fixed hook 34 is biased upward by an unillustrated elastic member provided in the front portion 31c, and if a pressing force is applied to the grip portion 342, the projecting amount of the hook portion 341 from the upper end portion of the front portion 31c is reduced together with the grip portion 342. If the force of the pressing applied to the grip portion 342 is removed, the projecting amount of the fixing hook 34 from the upper end portion of the front surface portion 31c of the frame body portion 31 is restored to the original projecting amount. The rear surface 341a of the hook portion 341 is a slope that approaches forward as it goes to the upper end side. Further, the hook portion 341 is configured such that a surface in contact with the inner wall surface of the fan unit housing portion 22 becomes a flat surface, the fan unit 30 is housed in the fan unit housing portion 22, and if a force for pressing the fan unit 30 forward from the fan unit housing portion 22 is applied by a pressing function provided inside the fan unit housing portion 22, a part of the flat surface of the hook portion 341 comes into contact with the inner wall surface of the fan unit housing portion 22, and is fixed to the fan unit housing portion 22 by a repulsive force due to the contact and the above-described pressing force.

In the case of a structure in which the fan unit 30 is attached to and detached from the fan unit housing portion 22 from the side of the industrial equipment 100, the fan unit 30 may be provided with a grip portion 342 on a surface on the side in the direction of detachment from the fan unit housing portion 22. Specifically, in the case of a structure in which the fan unit 30 is attached to and detached from the fan unit housing 22 from the left side of the industrial equipment 100, the fan unit 30 may be provided with the grip portion 342 on the left side surface. Similarly, in the case of a structure in which the fan unit 30 is attached to and detached from the fan unit housing 22 from the right side of the industrial equipment 100, the fan unit 30 may be provided with the grip portion 342 on the right side surface.

Fig. 5 is a perspective view of the fan unit of the industrial equipment according to embodiment 1, and shows a state in which the fan unit 30 is viewed obliquely from the rear. A projection 31e projecting rearward is provided on the rear surface 31d of the housing portion 31 of the fan unit 30, and a connector 35 is disposed on the projection 31 e.

Fig. 6 is a perspective view of a housing of a fan unit of an industrial device according to embodiment 1. The fan unit 30 is provided with a filter 36 below a space where the fan 32 is provided. That is, the fan unit 30 has a filter 36 on the intake side of the fan 32. The filter 36 is a metal mesh, and if cleaning work is periodically performed to remove the attached dust, it is not necessary to replace the filter 36 itself. By disposing the filter 36 in the fan unit 30, it is possible to prevent dust from being included in the air flow generated by the fan unit 30 and from adhering to the electronic component to be cooled.

Fig. 7 is a perspective view showing a housing portion of the fan unit of the industrial equipment according to embodiment 1, and shows a state in which the fan unit 30 is viewed obliquely from below. A grid-like cover portion 37 that covers the opening of the lower surface of the housing portion 31 is attached to the fan unit 30. The cover 37 attached to the housing 31 constitutes a lower surface of the fan unit 30.

Fig. 8 is a sectional view of a housing portion of a fan unit of an industrial device according to embodiment 1. Fig. 8 shows a cross section along line VIII-VIII in fig. 7. Since the spatial distance L capable of maintaining the insulation state between the filter 36 and the outside of the fan unit 30 is ensured between the filter 36 and the cover 37, a finger cannot be brought close to the filter 36 to a distance at which the insulation state between the finger and the filter 36 cannot be maintained. Therefore, the industrial equipment 100 according to embodiment 1 can prevent malfunction due to static electricity generated from the filter 36 by a finger.

Fig. 9 is a diagram showing a state in which a cover section of a fan unit of the industrial equipment according to embodiment 1 is opened. Fig. 10 is a diagram showing a state in which a cover section of a fan unit of an industrial device according to embodiment 1 is opened. The cover portion 37 is rotatable with respect to the frame body portion 31 of the fan unit 30 by a folding structure provided at an end portion of the fan unit 30 on the side of the attachment direction to the fan unit housing portion 22. In embodiment 1, the end of the fan unit 30 on the side of the fan unit housing 22 in the mounting direction is the rear end 37 a. In the case of a structure in which the fan unit 30 is attached to and detached from the fan unit housing portion 22 from the left side, the end of the fan unit 30 on the side of the fan unit housing portion 22 in the attachment direction is the right end. In the case of a structure in which the fan unit 30 is attached to and detached from the fan unit housing 22 from the right side, the end of the fan unit 30 on the side of the fan unit housing 22 in the attachment direction is the left end. The cover portion 37 rotates between a closed position covering the filter 36 and an open position exposing the filter 36. A claw 37c that engages with the housing portion 31 of the fan unit 30 is provided at the distal end portion 37b of the cover portion 37. A side surface 37d of the cover 37 is formed with a recess 37e for opening operation to be held when an operation of releasing the engagement between the claw 37c and the housing portion 31 of the fan unit 30 is performed. The recess 37e is an opening operation portion that receives an operation of opening the cover 37. Since the fan unit 30 has a folded structure, the filter 36 can be easily exposed, and maintenance of the filter 36 can be easily performed.

Fig. 11 is a perspective view of a fan unit housing section of the industrial equipment according to embodiment 1. Fig. 12 is an enlarged view of a fan unit housing section of the industrial equipment according to embodiment 1. In the industrial equipment 100 according to embodiment 1, the fan unit fixing and guiding portions 22c that engage with the guiding ribs 33 of the fan unit 30 are provided on the left wall 22a and the right wall 22b of the fan unit housing portion 22. The industrial equipment 100 further includes a substrate 26 on which the connector 22e is mounted, behind the fan unit housing 22. A notch 22f is provided in the wall 22d behind the fan unit housing portion 22, and the connector 22e is disposed in the notch 22 f. Therefore, the connector 22e can be inserted into and removed from the rear wall 22d of the fan unit housing 22 through the notch 22f from the front.

The industrial equipment 100 has a recess 23 formed above the fan unit housing 22. The recess 23 reaches the front surface 21a of the housing 21 of the industrial equipment 100, and a finger can be inserted into the recess 23 from the front of the industrial equipment 100. The industrial device 100 has engaging portions 24 that engage with the hook portions 341 of the fixing hooks 34 formed on both the left and right ribs of the concave portion 23. An engagement wall 241 extending downward is provided in front of the engagement portion 24. When the hook portion 341 is disposed in the engaging portion 24, the hook portion 341 and the engaging wall 241 are engaged with each other.

In a state where the grip portion 342 is gripped and the fixing hook 34 is pushed into the front portion 31c, the engagement wall 241 does not interfere with the hook portion 341. That is, if the grip portion 342 is gripped and the fixed hook 34 is pressed into the front portion 31c, the engagement between the hook portion 341 and the engagement wall 241 is released.

Since the connector 35 on the fan unit 30 side is provided on the convex portion 31e provided on the rear surface 31d, the connector 35 can be fitted to the connector 22e disposed behind the wall 22d by passing the convex portion 31e through the notch 22 f.

When the fan unit 30 is detached from the industrial equipment 100, a thumb is inserted into the recess 23 while pressing the cover 37, which is the lower surface of the fan unit 30, with a finger other than the thumb. Since a gap is secured below the industrial equipment 100 to allow the fan unit 30 to suck air, the lower surface of the fan unit 30 can be pressed with a finger in a state where the industrial equipment 100 is fixed to the support member 70. Then, the holding portion 342 is pressed downward by the thumb to press the fixing hook 34 into the front surface portion 31c, and the engagement between the hook portion 341 and the engagement wall 241 is released. Since the insertion and removal direction of the connectors 35 and 22e coincides with the direction in which the fan unit fixing guide portion 22c extends, the fan unit 30 is pulled forward with the engagement between the hook portion 341 and the engagement wall 241 released, and the connectors 35 and 22e are disengaged from each other. When the fan unit 30 is pulled forward in a state where the connectors 35 and 22e are disengaged, the guide rib 33 is guided by the fan unit fixing guide portion 22c, and the fan unit 30 slides and is separated forward of the industrial equipment 100.

When the fan unit 30 is attached to the industrial equipment 100, the guide rib 33 and the fan unit fixing guide portion 22c are aligned, and the fan unit 30 is pushed rearward. If the rear surface 341a of the hook portion 341 abuts against the front surface of the engagement wall 241, the fixing hook 34 is pushed into the front surface portion 31c, and the fan unit 30 approaches the wall 22d behind the fan unit housing portion 22. If the fan unit 30 reaches the rear of the fan unit housing portion 22, the connector 35 and the connector 22e are fitted. Since the hook portion 341 is positioned rearward of the engaging wall 241 when the connectors 35 and 22e are fitted, the fixing hook 34 is disposed at the engaging portion 24 by the elastic force of the elastic member, and the hook portion 341 engages with the engaging wall 241. The hook 341 and the engagement wall 241 are engaged with each other, whereby the fan unit 30 is fixed to the industrial equipment 100. Therefore, the industrial equipment 100 according to embodiment 1 can mount the fan unit 30 by press-fitting the fan unit 30 into the fan unit housing 22.

Fig. 13 is a perspective view of the industrial equipment according to embodiment 1, as viewed from the rear lower side. If the fan unit 30 is fixed to the industrial equipment 100, the opening operation recess 37e formed in the side surface 37d of the cover 37 is hidden by the housing 21 of the industrial equipment 100. Therefore, the cover 37 cannot be opened in a state where the fan unit 30 is fixed to the industrial equipment 100.

Since the cover 37 is rotatably attached to the frame portion 31 of the fan unit 30 by a folded structure provided at the rear end portion 37a, when the fan unit 30 is gripped to attach the fan unit 30 to the industrial equipment 100, the cover 37, which is the lower surface of the fan unit 30, is pressed by a finger other than the thumb, and a closing force is applied to the cover 37. Therefore, if the fan unit 30 is attempted to be attached to the fan unit housing 22 in a state where the cover 37 is not closed, the cover 37 is closed at the time of gripping the fan unit 30. Therefore, the industrial equipment 100 according to embodiment 1 prevents the cover 37 from being inadvertently opened during operation.

The folded structure is not necessarily provided at the rear end 37a of the cover 37, but may be provided at the front end 37b of the cover 37. If the folded structure is provided at the front end portion 37b of the cover 37, a force for closing the cover 37 can be applied even when the bottom surface of the fan unit 30 is gripped with the cover 37 fully opened.

In the industrial equipment 100 according to embodiment 1, since the grip portion 342 operated when releasing the engagement between the fan unit 30 and the industrial equipment 100 is exposed on the front surface 21a side of the housing 21 of the industrial equipment 100, the removal operation of the fan unit 30 can be performed from the front of the industrial equipment 100. In the industrial equipment 100 according to embodiment 1, since the operation of separating the fan unit 30 from the industrial equipment 100 is performed after the operation of releasing the engagement between the fan unit 30 and the industrial equipment 100, the fan unit 30 can be easily detached from the industrial equipment 100. Similarly, in the industrial equipment 100 according to embodiment 1, since the installation work is performed from the front of the industrial equipment 100 even when the fan unit 30 is installed, the fan unit 30 can be easily installed to the industrial equipment 100. Further, since the industrial equipment 100 according to embodiment 1 can attach and detach the fan unit 30 from the front, it is not necessary to secure a space for attaching and detaching the fan unit 30 above or below the industrial equipment 100.

In the industrial equipment 100 according to embodiment 1, the fan unit 30 is provided at the corner between the front surface 21a and the lower surface 21b of the housing 21, so that a continuous space that is not divided by the fan unit 30 can be secured inside the housing 21. Thus, in the case where the industrial equipment 100 has a plurality of electronic substrates on which electronic components are mounted, for example, the plurality of electronic substrates can be arranged close to each other, and thus the electric wiring between the electronic substrates can be laid easily. With the above configuration, the industrial equipment 100 can secure the degree of freedom in arrangement of the electronic components.

In the industrial equipment 100 according to embodiment 1, the fan unit 30 is provided at the corner between the front surface 21a and the lower surface 21b of the housing 21, and thus the fan unit 30 can be removed and easily replaced even when used in a state of being fixed on the back surface and supported by the support member 70.

Further, if the fan unit is provided on the upper surface of the industrial equipment, it is necessary to provide an operation portion for operation of attaching and detaching the fan unit and a positioning portion for positioning the fan unit on the upper surface of the industrial equipment, and the attachment and detachment work of the fan unit has to be performed from the upper surface side of the industrial equipment. Therefore, if the fan unit is provided on the upper surface side of the industrial equipment, workability of the attachment and detachment work of the fan unit is lowered. Further, it is necessary to secure a space for attaching and detaching the fan unit above the industrial equipment, and when the space for operation cannot be secured, there is a problem that the industrial equipment has to be detached from the base unit and the attaching and detaching operation of the fan unit has to be performed. The industrial equipment 100 according to embodiment 1 can solve the above-described problems.

Further, even when the fan unit is provided on the lower surface of the industrial equipment, it is necessary to secure a space for attaching and detaching the fan unit below the industrial equipment, and when the space for operation cannot be secured, there is a problem that the industrial equipment has to be detached from the base unit and the operation of attaching and detaching the fan unit has to be performed. The industrial equipment 100 according to embodiment 1 can solve the above-described problems.

In the industrial equipment 100 according to embodiment 1, since the filter 36 is mounted on the detachable fan unit 30, the filter 36 can be cleaned in a state where the fan unit 30 is detached from the industrial equipment 100, and therefore, the workability of cleaning the filter 36 is improved as compared with a structure in which the filter 36 is attached to the industrial equipment 100 side. Further, the industrial equipment 100 according to embodiment 1 does not require a space for cleaning the filter 36 to be secured below the industrial equipment 100, and therefore the dead space when the industrial equipment 100 is operated can be reduced.

In the industrial equipment 100 according to embodiment 1, since the filter 36 does not need to be provided on the lower surface of the entire housing 21, the cleaning operation of the filter 36 can be easily performed even when the industrial equipment 100 is large in size. When the fan unit 30 is disposed above the object to be cooled, if the filter 36 is made small, the airflow flowing in the industrial equipment 100 becomes small, resulting in a reduction in cooling performance, but the industrial equipment 100 according to embodiment 1 blows the airflow toward the object to be cooled from below, and therefore the cooling performance is not impaired even if the filter 36 is made small.

Since the industrial equipment 100 according to embodiment 1 blows an air flow toward the cooling target from below, even when the electronic component generating heat is the cooling target, the fan 32 is not baked by the heat generated by the electronic component, and the durability of the fan 32 can be improved.

In the above description, the mechanism for opening and closing the cover portion 37 has a folded structure, but a sliding structure may be adopted. The cover 37 may not have a folded structure or a sliding structure, but may be separated from the frame 31 of the fan unit 30 when opened. By providing a structure that is separated from the frame portion 31 of the fan unit 30 when opened, the shapes of the frame portion 31 and the cover portion 37 of the fan unit 30 can be simplified, and the manufacturing cost can be reduced.

The filter 36 is not limited to a metal filter, and may be a resin filter. The filter 36 is not limited to a filter that can be reused by cleaning, and may be a disposable filter such as a glass fiber filter. Further, as the filter 36, a filter which can be reused by cleaning and a disposable filter may be used in combination.

Embodiment 2.

Fig. 14 is a perspective view showing the structure of an industrial apparatus according to embodiment 2 of the present invention. In fig. 14, a part of the industrial equipment 110 is omitted from illustration in order to facilitate understanding of the structure of the industrial equipment 110. The industrial equipment 110 according to embodiment 2 is different from the industrial equipment 100 according to embodiment 1 in that a partition plate 25 that restricts an arrival range of an air flow is provided inside a housing 21. The partition plate 25 is disposed on a side surface of the fan unit housing 22. Here, since the structure in which the fan unit 30 is attached and detached from the front of the industrial equipment 110 is described, the partition plate 25 is positioned on the left and right sides of the fan unit housing 22, but in the case of the structure in which the fan unit 30 is attached and detached from the side of the industrial equipment 110, the partition plate 25 disposed on the side surface of the fan unit housing 22 is positioned in the front and rear of the fan unit housing 22. In embodiment 2, the partition plate 25 is a planar member. The industrial equipment 110 has electronic components to be cooled mounted on a portion sandwiched by the partition plates 25. That is, the industrial equipment 110 is provided with electronic components generating heat on the same side as the fan unit 30 with the partition plate 25 as a boundary. By providing the partition plate 25 inside the housing 21, the airflow generated by the fan unit 30 does not blow on electronic components that are not the cooling target.

In the case where the partition plate 25 is not provided inside the housing 21, air is also drawn into the airflow blown out from the fan unit 30 at a portion where the airflow blown out from the fan unit 30 is not directly blown, and another airflow is generated. In the industrial equipment 110 according to embodiment 2, since the partition plate 25 is provided inside the housing 21, another air flow is not generated in a portion to which the air flow blown out from the fan unit 30 is not directly blown.

The industrial equipment 110 according to embodiment 2 can improve cooling efficiency by limiting the cooling range in which the fan unit 30 cools. In addition, since the range of dust entering the industrial equipment 110 can be limited, the size of the filter 36 can be reduced.

In addition, when the industrial equipment 110 incorporates a plurality of electronic components serving as heat generation sources, the electronic components that generate heat during operation are collected in the cooling range cooled by the fan unit 30, and the electronic components that do not generate heat are collected outside the cooling range cooled by the fan unit 30, so that the temperature rise of the electronic components that do not generate heat can be suppressed.

In addition, in the interior of the housing 21, the airflow blown out from the fan unit 30 and the other airflow generated by the airflow blown out from the fan unit 30 do not pass through the portion partitioned from the fan unit 30 by the partition plate 25, that is, outside the cooling range cooled by the fan 32, so that it is possible to prevent dust from adhering to the electronic components outside the cooling range cooled by the fan 32.

The configuration described in the above embodiment is an example of the contents of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or modified without departing from the scope of the present invention.
