Japanese Patent Application Publication No. 2005-156096

In the storage described in Patent Document 1 mentioned above, when the air filter is attached to the front of the condenser, the operator's hand may enter the machine room when attaching and detaching the air filter for maintenance. There is a risk of interference with members (mechanical parts, wiring, etc.) in the machine room. On the other hand, if the air filter is installed in front of the air intake port on the front panel, it is easy for the user of the storage room to inadvertently interfere with the air filter, which may cause the air filter to shift or fall off. may occur.

The technology described in this specification was developed based on the above circumstances, and it makes it difficult for workers to interfere with the members inside the machine room, and also prevents users from inadvertently interfering with the air filter. The purpose is to make it difficult.

(1) A storage related to the technology described in this specification includes a storage main body including at least a machine room having an opening, a first panel attached to the storage main body so as to cover the opening, the storage main body and the first panel. The air filter includes a second panel attached to at least one of the first panel and the second panel, and an air filter interposed between the first panel and the second panel and covered by the second panel.

According to the storage with the above configuration, the opening of the machine room provided in the storage main body is covered by the first panel, and the air filter is interposed between the first panel and the second panel. Therefore, when cleaning the air filter, the operator only has to remove the air filter interposed between the first panel and the second panel, thereby avoiding the operator's hands entering into the machine room. This prevents the operator from interfering with members (mechanical parts, wiring, etc.) in the machine room when attaching and detaching the air filter. The air filter interposed between the first panel and the second panel is covered by the second panel attached to at least one of the storage main body and the first panel. Therefore, it becomes difficult for the user of the storage to inadvertently interfere with the air filter during use. This makes it difficult for the air filter to be accidentally displaced or dropped. Moreover, since the air filter is covered by the second panel, the appearance is excellent.

(2) Moreover, the second panel is attached to the first panel of the storage main body and the first panel. In this way, when performing maintenance in the machine room, it is sufficient to remove the first panel with the second panel attached from the storage main body. That is, since the first panel and the second panel can be removed from the storage main body all at once, the workability when performing maintenance inside the machine room becomes excellent.

(3) The second panel may be opened and closed relative to the first panel so as to be in either a closed state that covers the air filter or an open state that exposes the air filter to the outside. installed. In this way, when cleaning the air filter, the second panel attached to the first panel is opened to expose the air filter to the outside. This makes it possible to attach and detach the air filter. After the cleaning is completed, the air filter can be covered by the second panel by closing the second panel attached to the first panel. In this way, when cleaning the air filter, there is no need to remove the second panel from the first panel, resulting in excellent workability.

(4) In addition, the first panel has a first panel-side magnetic part made of a magnetic material that is attracted to a magnet, whereas the second panel has a second panel made of a magnetic material that is attracted to a magnet. At least one of the first panel side magnetic part and the second panel side magnetic part is a magnet, and the magnetic force generated between the first panel side magnetic part and the second panel side magnetic part is used to magnetize the first panel side magnetic part. The second panel is held against the air filter, and the first panel side magnetic portion is arranged adjacent to the edge of the air filter to enable positioning of the air filter. In this way, the second panel is held attached to the first panel by the magnetic force generated between the first panel side magnetic section and the second panel side magnetic section. This provides excellent workability when changing the attachment state of the second panel to the first panel when cleaning the air filter or the like. When the air filter is attached to the first panel for cleaning the air filter, the first panel side magnetic portion is interfered with the edge of the air filter, and the air filter is positioned at an appropriate attachment position. This makes it difficult for the second panel covering the air filter to inadvertently interfere with the air filter.

(5) Further, the first panel is provided with an operation panel that can operate equipment provided in the storage, and the second panel is arranged to cover the operation panel. In this way, the operation panel is covered with the second panel together with the air filter, thereby preventing exposure to the outside. This makes it difficult for the operation panel to be operated erroneously, and provides an excellent appearance.

(6) Furthermore, the second panel is arranged to cover at least an area of the first panel extending from the air filter to the operation panel. In this way, at least the range from the air filter to the operation panel of the first panel is covered by the second panel and can be prevented from being exposed to the outside. This results in a more excellent appearance.

(7) Further, a workbench is provided on the top surface of the storage main body. In this way, the user of the storage can work using the workbench provided on the top of the storage main body. Since the air filter is covered by the second panel, it is difficult for the user to accidentally interfere with the air filter while working on the workbench.

According to the technology described in this specification, it is possible to make it difficult for an operator to interfere with members in the machine room, and to make it difficult for a user to inadvertently interfere with the air filter.

By making the filter section 31B disposable in this way, maintenance of the air filter 31 is facilitated.

Next, the relationship between the air filter 31 and the second panel magnet 33 will be explained. Of the two second panel magnets 33, the second panel magnet 33 arranged at the lower part of the first panel main body 30A is arranged so as to be adjacent to the edge of the air filter 31, as shown in FIGS. 4 and 8. It is arranged. Specifically, the second panel magnet 33 is arranged so as to protrude outward from the outer surface of the first panel body 30A (the surface facing the air filter 31) along the Y-axis direction, and the protruding portion is The filter bodies 31A of the filter main body 31A constituting the air filter 31 in the normal mounting position are arranged adjacent to each other, facing the outer edge of the short side extending along the Z-axis direction. Although the protruding portion of the second panel magnet 33 does not interfere with the filter main body 31A as long as the air filter 31 is in the normal mounting position with respect to the first panel 30, If the filter body 31A is misaligned in the X-axis direction, it will interfere with the outer edge of the short side of the filter body 31A. That is, the air filter 31 is positioned by the second panel magnet 33 so that it will not be displaced in the X-axis direction from the above-mentioned normal mounting position.

As shown in FIGS. 3 to 5, the second panel 32 has a shallow box shape that is vertically long and open on one side, and is made by bending a plate made of stainless steel, etc., which is a magnetic material that sticks to a magnet. As a result, it is formed into the shape shown above. In the second panel 32, like the first panel 30, the long side direction corresponds to the Z-axis direction, the short side direction corresponds to the X-axis direction, and the plate thickness direction corresponds to the Y-axis direction. The second panel 32 has a longer side dimension larger than that of the first panel 30, which makes it difficult for the first panel 30 to be exposed to the outside, which is suitable for maintaining a good appearance. The second panel 32 is configured such that one long side edge (on the right side in FIGS. 3 and 4) can be opened and closed relative to the one long side edge of the first panel 30 via a hinge 35. installed. The hinges 35 have rotation axes parallel to the Z-axis direction, and two hinges 35 are provided at positions (upper and lower) spaced apart in the Z-axis direction on the first panel 30 and the second panel 32. The second panel 32 is rotated relative to the first panel 30 around the rotation axis of the hinge 35, so that the second panel 32 is in an open state (see FIGS. 1 and 3) in which the first panel 30 and the air filter 31 are exposed to the outside. 8) and a closed state in which the air filter 31 is sandwiched between the first panel 30 (states shown in FIGS. 9 to 11). When the second panel 32 is opened and closed by swinging, the second panel 32 is pivoted around the edge of one long side attached to the first panel 30 by the hinge 35, and the edge of the other long side is rotated. It has become. As shown in FIG. 8, the second panel 32 in the open state has its main plate surface intersecting with the main plate surface of the first panel 30, and the edge on the other long side is at least The positional relationship is such that they do not overlap in the Y-axis direction with respect to the air filter 31. On the other hand, the second panel 32 in the closed state has its main plate surface parallel to the main plate surface of the first panel 30, as shown in FIG. are arranged so as to be close to and directly opposite the edges of the pair of long sides of the first panel 30. In other words, the second panel 32 in the closed state is in a positional relationship that overlaps the first panel 30 and the air filter 31 in the Y-axis direction, and covers almost the entire area of the first panel 30 and the air filter 31 from the outside. It is arranged to cover.

As shown in FIG. 3, the second panel 32 includes a second panel main body 32A having a vertically long plate shape, a side plate 32B protruding from the outer edge of the second panel main body 32A, and a second panel body 32B that is folded back from the protruding end of the side plate 32B. It has a folded piece portion 32C that faces the panel main body 32A. As shown in FIGS. 6 and 9, an air intake port 32A1 is provided in a portion (lower portion) of the second panel main body 32A that faces the lower portion (area where the air intake port 30A1 is formed) of the first panel main body 30A in the closed state. An opening is formed. The intake ports 32A1 have a horizontally elongated oval shape when viewed from the front, and a plurality of intake ports 32A1 are arranged in a staggered manner in the X-axis direction and the Z-axis direction within the main plate surface of the second panel body 32A. . Although the length and width of the air intake ports 32A1 of the second panel main body 32A are smaller than those of the air intake ports 30A1 of the first panel main body 30A, the number of air intake ports 32A1 is greater than that of the air intake ports 30A1. When the second panel 32 is in the closed state, the air intake port 32A1 of the second panel main body 32A and the air intake port 30A1 of the first panel main body 30A are in a positional relationship in which they partially overlap. The outside air passed through the intake port 32A1 of the second panel main body 32A constituting the second panel 32 in the closed state is passed through the filter section 31B of the air filter 31 to remove dust, and then the first panel It is taken into the machine room 13 by passing through the air intake port 30A1 of the main body 30A. Furthermore, an exhaust port 32A2 is formed in a portion (upper portion) of the second panel main body 32A that faces the upper portion (formation area of the exhaust port 30A3) of the first panel main body 30A in the closed state.

As shown in FIG. 10, the side plate 32B has a shape that projects from the outer peripheral edge of the second panel body 32A toward the first panel 30 side along the Y-axis direction when the second panel 32 is in the closed state. There are four. Of the four side plates 32B, a hinge 35 is attached to the side plate 32B that is connected to the edge of one long side of the second panel main body 32A. As shown in FIG. 3, the folded pieces 32C are provided in a continuous manner with three side plates 32B, excluding the one located on the lower side, among the four side plates 32B. Among the three folded pieces 32C, there is a gap larger than the long side dimension (dimension in the X-axis direction) of the air filter 31 between the two folded pieces 32C that are connected to the two long side side plates 32B. is vacant. As a result, when the second panel 32 is in the closed state, the air filter 31 is housed between the two folded pieces 32C, as shown in FIG. Among the three folding pieces 32C, the folding pieces 32C that are connected to the side plate 32B that is connected to the other long side edge of the second panel main body 32A are two folded pieces that are spaced apart in the Z-axis direction, as shown in FIG. There are cutouts in places. Adsorption plates 36 that are attracted to the two second panel magnets 33 provided on the first panel 30 are attached to the two notches in the folded piece portion 32C, respectively. The adsorption plate 36 is made of a magnetic material such as stainless steel that sticks to a magnet, and constitutes a "second panel side magnetic section." The two suction plates 36 are aligned with the two second panel magnets 33 in the Z-axis direction. Therefore, when the second panel 32 is brought into the closed state, the suction plate 36 is attracted by the second panel magnet 33, and the second panel 32 is brought into the closed state due to the suction force. It is meant to be retained. As shown in FIG. 11, the suction plate 36 is attached to the inner surface of the folded piece 32C (the side facing the second panel main body 32A), and is attached to the plate of the folded piece 32C from the outer surface of the folded piece 32C. It is arranged so that it is recessed in thickness. The yoke 33B of the second panel magnet 33 is inserted into the notch of the folded piece 32C.

This embodiment has the structure as described above, and its operation will be explained next. When cleaning the air filter 31, as shown in FIGS. 4, 5, and 8, the second panel 32 constituting the panel unit 17 is opened to expose the air filter 31 to the outside. . The operator grasps and operates the handle portion 31A3 to release the adsorption state of the air filter magnet 34 to the first panel 30 and release the locked state of the mounting piece portion 31A4 to the edge of the mounting hole 30A2, while The air filter 31 can be removed from the first panel 30 by pulling it toward you. The filter portion 31B of the removed air filter 31 is replaced. The air filter 31 with the filter part 31B replaced is attached to the first panel 30 from the state shown in FIG. When installing the air filter 31, as shown in FIG. 31 is guided to the normal mounting position. Therefore, when rotating the second panel 32 from the open state to the closed state, the air filter 31 is less likely to be accidentally caught between the first panel 30 and the second panel 32, and the work Excellent in sex. After the air filter 31 is installed at the normal mounting position, when the second panel 32 is closed as shown in FIGS. 9 and 10, the air filter 31 is covered by the second panel 32. Become. At this time, the second panel 32 is held in the closed state by the second panel magnet 33 being attracted to the attraction plate 36 .

While the above-mentioned air filter 31 is being maintained, the opening 13A of the machine room 13 is always covered by the first panel 30, and the hand of the worker who is attaching and removing the air filter 31 enters the machine room 13. The situation is being avoided. This prevents the operator from interfering with members (mechanical parts, wiring, etc.) in the machine room 13 when attaching and detaching the air filter 31. Furthermore, when cleaning the air filter 31, it is only necessary to swing the second panel 32 open and close, and there is no need to remove the second panel 32 from the first panel 30, resulting in excellent workability.

On the other hand, when performing maintenance inside the machine room 13, the operator performs work to remove the first panel 30 that constitutes the panel unit 17 from the storage main body 11, as shown in FIGS. 9 and 10. When the first panel 30 is removed from the storage main body 11, the air filter 31 and the second panel 32 integrated with the first panel 30 are also removed from the storage main body 11 all at once. Thereafter, maintenance is performed by taking out the cooling unit 18 through the opening 13A of the machine room 13. When the first panel 30 is attached to the storage main body 11 after the maintenance, the air filter 31 and the second panel 32 integrated with the first panel 30 are also attached to the storage main body 11 at once. As a result of the above, the workability when performing maintenance inside the machine room 13 is excellent.

The user of the cooling storage 10 according to the present embodiment opens and closes the heat insulating door 14 to take items in and out of the storage room 12, and also performs cooking and other tasks on the workbench 15 (see FIG. ). While the user is performing the above-mentioned work around the storage main body 11, the air filter 31 is always covered from the outside by the second panel 32 in the closed state, as shown in FIGS. 9 and 10. It is being said. Therefore, it is difficult for the user of the cooling storage 10 to inadvertently interfere with the air filter 31 during use. This makes it difficult for the air filter 31 to be accidentally displaced or dropped. Moreover, since the air filter 31 is covered by the second panel 32, the appearance is excellent. Moreover, since the second panel 32 is arranged to cover the operation panel 30A4 in addition to the air filter 31, the operation panel 30A4 is less likely to be operated erroneously, and the appearance is excellent.

As explained above, the cooling storage (storage) 10 of the present embodiment includes a storage main body 11 including at least a machine room 13 having an opening 13A, a first panel 30 attached to the storage main body 11 in a manner covering the opening 13A, A second panel 32 attached to at least one of the storage main body 11 and the first panel 30; and an air filter 31 interposed between the first panel 30 and the second panel 32 and covered by the second panel 32. and.

This provides excellent workability when changing the attachment state of the second panel 32 to the first panel 30 when cleaning the air filter 31 or the like. When attaching the air filter 31 to the first panel 30 when cleaning the air filter 31, etc., the second panel magnet 33 may be interfered with the edge of the air filter 31, and the air filter 31 may not be placed in the appropriate mounting position. is positioned. This makes it difficult for the second panel 32 covering the air filter 31 to inadvertently interfere with the air filter 31.

Further, the first panel 30 is provided with an operation panel 30A4 that can operate the equipment provided in the cooling storage 10, and the second panel 32 is arranged to cover the operation panel 30A4. In this way, the operation panel 30A4 is covered with the second panel 32 together with the air filter 31, thereby avoiding exposure to the outside. This makes it difficult for the operation panel 30A4 to be operated erroneously, and provides an excellent appearance.

Further, the second panel 32 is arranged to cover at least a range of the first panel 30 from the air filter 31 to the operation panel 30A4. In this way, at least the range from the air filter 31 to the operation panel 30A4 of the first panel 30 is covered by the second panel 32 and can be prevented from being exposed to the outside. This results in a more excellent appearance.

Further, a workbench 15 is provided on the top surface of the storage main body 11. In this way, the user of the cooling storage 10 can work using the workbench 15 provided on the top surface of the storage main body 11. Since the air filter 31 is covered by the second panel 32, it is difficult for the user to accidentally interfere with the air filter 31 while working on the workbench 15.
