The concave portion 37 is an opening operation portion that receives an operation of opening the cover 37. Since the fan unit 30 has a hinge structure, the filter 36 can be easily exposed and the filter 36 can be easily maintained.

FIG. 11 is a perspective view of the fan unit storage part of the industrial device according to the first embodiment. FIG. 12 is an enlarged view of the fan unit storage unit of the industrial device according to the first embodiment. In the industrial device 100 according to the first embodiment, the fan unit fixing guide 22 c that engages with the guide rib 33 of the fan unit 30 is provided on the left wall 22 a and the right wall 22 b of the fan unit storage unit 22. Further, the industrial device 100 has a substrate 26 on which the connector 22e is mounted on the rear side of the fan unit storage unit 22. A notch 22f is provided in the wall 22d on the rear side of the fan unit storage portion 22, and the connector 22e is disposed at the notch 22f. Therefore, it is possible to insert / remove the connector 22e through the notch 22f from the front rather than the wall 22d behind the fan unit storage portion 22.

The industrial device 100 has a recess 23 formed above the fan unit storage unit 22. The recess 23 reaches the front surface 21 a of the housing 21 of the industrial device 100, and a finger can be inserted into the recess 23 from the front of the industrial device 100. In the industrial device 100, the engaging portions 24 that are engaged with the hook portions 341 of the fixed hooks 34 are formed on the left and right sides of the recess 23. An engaging wall 241 that extends downward is present in front of the engaging 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.

In the state where the grip portion 342 is gripped and the fixed hook 34 is pushed into the front surface portion 31c, the engagement wall 241 does not interfere with the hook portion 341. That is, when the grip portion 342 is gripped and the fixed hook 34 is pushed into the front surface 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 installed on the convex portion 31e provided on the rear surface 31d, the convex portion 31e passes through the notch 22f, so that the connector 22e disposed behind the wall 22d is connected to the connector 22e. The connector 35 can be fitted.

When removing the fan unit 30 from the industrial device 100, the thumb is inserted into the recess 23 while pressing the cover 37 forming the lower surface of the fan unit 30 with a finger other than the thumb. Since a gap is secured below the industrial device 100 for the fan unit 30 to take in air, the lower surface of the fan unit 30 is held with a finger while the industrial device 100 is fixed to the support member 70. I can hold it down. Then, the grip portion 342 is pushed downward with the thumb to push 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 directions of the

connectors

35 and 22e coincide with the direction in which the fan unit fixing guide 22c extends, the fan unit 30 is pulled forward while the engagement between the hook portion 341 and the engagement wall 241 is released. The

connectors

35 and 22e are disengaged. By pulling the fan unit 30 further forward with the

connectors

35 and 22e disengaged, the guide rib 33 is guided by the fan unit fixing guide 22c, and the fan unit 30 slides and separates to the front of the industrial device 100. To do.

When the fan unit 30 is attached to the industrial device 100, the guide rib 33 and the fan unit fixing guide 22c are aligned and the fan unit 30 is pushed backward. When the rear surface 341a of the hook portion 341 and the front surface of the engagement wall 241 come into contact with each other, the fan unit 30 approaches the rear wall 22d of the fan unit storage portion 22 while the fixing hook 34 is pushed into the front portion 31c. When the fan unit 30 reaches the rear of the fan unit storage part 22, the connector 35 and the connector 22e are fitted. When the

connectors

35 and 22e are fitted, the hook portion 341 is positioned behind the engagement wall 241. Therefore, the fixed hook 34 is disposed in the engagement portion 24 by the elastic force of the elastic member, and the hook portion 341 and the engagement wall 241 engages. The fan unit 30 is fixed to the industrial device 100 by the hook portion 341 and the engagement wall 241 engaging with each other. Therefore, the industrial device 100 according to the first embodiment can attach the fan unit 30 by pushing the fan unit 30 into the fan unit storage unit 22.

FIG. 13 is a perspective view of the industrial device according to the first embodiment as viewed from the rear lower side. When the fan unit 30 is fixed to the industrial device 100, the opening operation recess 37 e formed on the side surface 37 d of the cover 37 is hidden by the housing 21 of the industrial device 100. Therefore, when the fan unit 30 is fixed to the industrial device 100, the cover 37 cannot be opened.

Further, since the cover 37 is pivotally attached to the casing 31 of the fan unit 30 by a hinge structure provided at the rear end portion 37a, the fan unit 30 is attached to the industrial device 100. When gripping 30, the cover 37 forming 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 to be attached to the fan unit storage unit 22 in a state where the cover 37 is not closed, the cover 37 is closed when the fan unit 30 is gripped. Therefore, the industrial device 100 according to Embodiment 1 is prevented from opening the cover 37 unexpectedly during operation.

Note that the hinge structure is not necessarily provided at the rear end portion 37 a of the cover 37, and may be provided at the front end portion 37 b of the cover 37. When the hinge structure is provided at the front end portion 37 b of the cover 37, it is possible to apply a closing force to the cover 37 when gripping the lower surface of the fan unit 30 even when the cover 37 is fully opened.

In the industrial device 100 according to the first embodiment, the grip portion 342 that is operated when releasing the engagement between the fan unit 30 and the industrial device 100 is exposed to the front surface 21a side of the housing 21 of the industrial device 100. Therefore, the fan unit 30 can be removed from the front of the industrial device 100. Further, the industrial device 100 according to the first embodiment can perform an operation of separating the fan unit 30 from the industrial device 100 following the operation of releasing the engagement between the fan unit 30 and the industrial device 100. The unit 30 can be easily detached from the industrial device 100. Similarly, the industrial device 100 according to the first embodiment can be mounted from the front of the industrial device 100 when the fan unit 30 is mounted. Therefore, the fan unit 30 can be easily mounted to the industrial device 100. . Moreover, since the industrial apparatus 100 which concerns on Embodiment 1 can attach or detach the fan unit 30 from the front, it is not necessary to ensure the space for the attachment or detachment work of the fan unit 30 above or below the industrial apparatus 100.

Further, the industrial device 100 according to the first embodiment includes the fan unit 30 at the corner formed by the front surface 21 a and the lower surface 21 b of the housing 21, so that the fan unit 30 is provided inside the housing 21. It is possible to secure a unified space that is not divided. Thereby, for example, when there are a plurality of electronic boards on which electronic components are mounted, the industrial device 100 can arrange the plurality of electronic boards close to each other, so that electrical wiring between the electronic boards can be easily laid. can do. In this way, the industrial device 100 can ensure the degree of freedom of electronic component placement.

Further, the industrial device 100 according to the first embodiment is provided with the fan unit 30 at the corner portion formed by the front surface 21a and the lower surface 21b of the housing 21, so that the back surface is fixed to the support member 70. Even when used in a supported state, the fan unit 30 can be removed and replaced easily.

Also, if a fan unit is installed on the upper surface of an industrial device, it is necessary to provide an operation unit for operating the fan unit and a positioning unit for positioning the fan unit on the upper surface of the industrial device. Unit attachment / detachment work must be performed from the top side of the industrial equipment. Therefore, if the fan unit is installed on the upper surface side of the industrial equipment, the workability of the fan unit attaching / detaching work is lowered. In addition, if it is necessary to secure a space for attaching / detaching the fan unit above the industrial equipment, and the work space cannot be secured, remove the industrial equipment from the base unit and attach / detach the fan unit. There is a problem that it must be. The industrial device 100 according to the first embodiment can solve such a problem.

Similarly, if a fan unit is installed on the lower surface of an industrial device, it is necessary to secure a space for attaching / detaching the fan unit below the industrial device. However, there is a problem that the fan unit must be attached and detached by removing the industrial equipment from the base unit. The industrial device 100 according to the first embodiment can solve such a problem.

Moreover, since the industrial device 100 according to Embodiment 1 has the filter 36 mounted on the detachable fan unit 30, the filter 36 can be cleaned with the fan unit 30 removed from the industrial device 100. As compared with the structure in which the filter 36 is attached to the industrial equipment 100 side, the cleaning workability of the filter 36 is improved. Furthermore, since the industrial device 100 according to the first embodiment does not need to secure a space for cleaning the filter 36 below the industrial device 100, the dead space for operating the industrial device 100 is reduced. it can.

Since the industrial device 100 according to the first embodiment does not need to be provided with the filter 36 on the entire lower surface of the housing 21, the cleaning operation of the filter 36 can be easily performed even when the size of the industrial device 100 is large. When the fan unit 30 is arranged above the object to be cooled, if the filter 36 is made small, the airflow flowing through the industrial equipment 100 becomes thin and the cooling performance deteriorates, but the industrial equipment according to the first embodiment. Since the airflow 100 blows the airflow to the cooling target from below, the cooling performance is not impaired even if the filter 36 is made small.

Since the industrial device 100 according to the first embodiment blows an airflow from below to the cooling target, even when the electronic component that generates heat is the cooling target, the fan 32 is not blown by the heat generated by the electronic component, The durability of the fan 32 can be improved.

In the above description, the mechanism for opening and closing the cover 37 has a hinge structure, but a slide structure may be used. The cover 37 may have a structure that does not have a hinge structure and a slide structure and is separated from the casing 31 of the fan unit 30 when released. By adopting a structure that separates from the casing 31 of the fan unit 30 when released, the shapes of the casing 31 and the cover 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. Further, 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, the filter 36 may be used in combination with a filter that can be reused by cleaning and a disposable filter.

Embodiment 2. FIG.
FIG. 14 is a perspective view showing a configuration of an industrial device according to Embodiment 2 of the present invention. In FIG. 14, a part of the industrial device 110 is not shown for easy understanding of the structure of the industrial device 110. The industrial device 110 according to the second embodiment is different from the industrial device 100 according to the first embodiment in that a partition plate 25 that restricts the reach of the airflow is provided inside the housing 21. The partition plate 25 is disposed on the side surface of the fan unit storage unit 22. Here, since the structure in which the fan unit 30 is attached and detached from the front of the industrial device 110 is described, the partition plate 25 is positioned on the left and right of the fan unit storage unit 22. In the case of a structure that is detachable from the side of 110, the partition plates 25 arranged on the side surface of the fan unit storage unit 22 are positioned in front of and behind the fan unit storage unit 22. In the second embodiment, the partition plate 25 is a planar member. In the industrial device 110, electronic parts to be cooled are mounted on a portion sandwiched between the partition plates 25. That is, in the industrial device 110, electronic components that generate heat are arranged on the same side as the fan unit 30 with the partition plate 25 as a boundary. Since the partition plate 25 is provided inside the housing 21, the air current generated by the fan unit 30 is not applied to electronic components that are not to be cooled.

In addition, when the partition plate 25 does not exist inside the casing 21, another airflow is generated by sucking air into the airflow output from the fan unit 30 even in a portion where the airflow output from the fan unit 30 does not directly hit. Will occur. Since the industrial device 110 according to the second embodiment is provided with the partition plate 25 inside the housing 21, another airflow is not generated in a portion where the airflow emitted from the fan unit 30 does not directly hit.

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

When the industrial device 110 includes a plurality of electronic components that serve as heat sources, the electronic components that generate heat during operation are collected in the cooling range by the fan unit 30, and the electronic components that do not generate heat are cooled by the fan unit 30. By concentrating out of the range, it is possible to suppress an increase in the temperature of the electronic component that does not generate heat.

Further, in the inside of the casing 21, the airflow from the fan unit 30 and the airflow from the fan unit 30 are generated outside the cooling range of the fan 32 by the part separated from the fan unit 30 by the partition plate 25.
