With reference to FIGS. 1 to 4, a blower device according to a first embodiment of the present invention will be described. FIG. 1 shows the outer appearance of air blower 101 in the present embodiment. The blower device 101 includes a main body 1 and a front plate 2 attached to the front side of the main body 1. A gap 5 is provided between the main body 1 and the front plate 2. Air outlets 4 are provided near the left and right ends on the front side of the main body 1. In the example shown in FIG. 1, the air blower 101 is of a type that is used by hanging it on a wall, but this is merely an example, and a type that is used by placing it on the floor may be used. When the blower is to be placed on the floor for use, the blower may have legs, wheels, etc. at the bottom. A schematic cross-sectional view of the blower device 101 is shown in FIG. FIG. 2 is a top view of the cross section.

As shown by an arrow 81 in FIG. 2, the air that has entered the back side of the front plate 2 through the gap 5 is treated as necessary inside the main body 1, and is divided into right and left as shown by an arrow 82. As it progresses, it exits the main body 1 through the air outlet 4 as shown by the arrow 83.

The main body 1 has an intake port 3 on the front side. A filter 7 is installed on the back side of the front plate 2 so as to cover the intake port 3. The filter 7 is supported by the drive units 8a and 8b. The driving units 8a and 8b can send the filter 7 in the second direction 92. When the drive units 8a and 8b are driven, the filter 7 is sent to either the left or right direction in FIG.

Filter cleaning tools 10 a and 10 b are installed on the back side of the front plate 2. The front plate 2 is connected to the main body 1 via front plate support portions 12a and 12b. The front plate 2 is supported by the front plate support portions 12a and 12b.

An exploded view of the blower device 101 is shown in FIG. It can be seen that the filter 7 is arranged between the front plate 2 and the main body 1. Filter cleaning tools 10 a and 10 b are arranged on the back side of the front plate 2. The filter cleaning tools 10a and 10b are not parallel to each other, and are arranged in an inclined posture so that the interval is narrower on the upper side and wider on the lower side.

The relationship between the filter 7 and the filter cleaning tools 10a and 10b in the blower 101 is schematically shown in FIG.

The blower device 101 has a main body 1 having an intake opening 3 as an air passage opening having a central axis 6 along the first direction 91 defined in a horizontal plane, and at least covering the air passage opening, A filter 7 having a constant width in the vertical direction, extending in a second direction 92 defined in a horizontal plane and perpendicular to the first direction 91, and extending longer than the width of the air passage opening along the second direction 92; Drive portions 8a and 8b for moving the filter 7 in the second direction 92, and a long shape, along the surface of the filter 7 while abutting against the surface of the filter 7 so as to scrape off dust adhering to the surface of the filter 7 And the filter cleaning tools 10a and 10b that extend in a posture inclined with respect to the vertical direction when viewed from a direction perpendicular to the surface of the filter 7.

(Action/effect)
Blower 101 in the present exemplary embodiment includes filter 7 extending sufficiently long, and drive unit 8a, 8b can move this filter 7 in second direction 92. By moving the filter 7 in the second direction 92, the filter cleaning tools 10a and 10b can relatively scrape the surface of the filter 7. Since the filter cleaning tools 10a and 10b are in contact with the surface of the filter 7 and extend in a posture inclined with respect to the vertical direction when viewed from the direction perpendicular to the surface of the filter 7, they are scraped while removing dust. can do. Thus, the dust attached to the filter 7 can be efficiently removed.

The drive units 8a and 8b can move the filter 7 toward the first side, which is one side in the second direction 92, and the filter cleaning tool has a lower end closer to the first side than an upper end. It is preferable that they are arranged so as to be located at. By adopting this configuration, it is possible to avoid dust, which is separated from the filter on the upper portion of the filter cleaning tool, from being caught on the lower portion of the filter cleaning tool as much as possible.

In the structure shown in FIG. 4, the “first side which is one side of the second direction 92” is, for example, the right side. The filter 7 can be moved toward the right side, and the filter cleaning tool 10b is arranged so that the lower end is located closer to the right side than the upper end. When one air blower is provided with a plurality of filter cleaning tools, this condition may be satisfied in at least one filter cleaning tool.

If it is assumed that the “first side, which is one side of the second direction 92 ”, is the left side, the issue is whether the filter 7 can be moved toward the left side. Then, it becomes a problem whether or not there is a filter cleaning tool arranged such that the lower end is located closer to the left side than the upper end. In the configuration shown in FIG. 4, the filter 7 can be moved to the left, and the filter cleaning tool 10a satisfies the above conditions.

The filter cleaning tools 10a and 10b preferably include brushes. By adopting this configuration, it is possible to realize a structure suitable for cleaning the filter with a simple structure. If there are multiple filter cleaning tools, then at least one of the plurality of filter cleaning tools may only include a brush. The plurality of filter cleaning tools may be a combination of cleaning tools having different structures.

The air passage port is preferably the intake port 3 provided on the front surface of the main body 1. By adopting this configuration, it is possible to filter out dust mixed in with the outside air before entering the main body 1, and this dust can be removed from the filter by the filter cleaning tool. Although the description has been given here based on the example in which the air passage port is the intake port, the air passage port may be other than the intake port. For example, the air passage port may be an air outlet.

(Embodiment 2)
(Constitution)
With reference to Drawing 5-Drawing 6, a blower in Embodiment 2 based on the present invention is explained. FIG. 5 shows a schematic configuration of the blower device 102 in the present embodiment.

Blower 102 has the same basic configuration as blower 101 shown in the first embodiment, but differs in the following points.

The blower device 102 includes dust receiving portions 11a and 11b below the filter cleaning tools 10a and 10b for receiving dust falling from the filter 7 or the filter cleaning tools 10a and 10b. By adopting this configuration, dust can be efficiently collected by the dust receiving portions 11a and 11b. Here, the left and right filter cleaning tools 10a and 10b and the dust receiving parts 11a and 11b have been described, but the left and right sides do not necessarily have to satisfy the above conditions. It is sufficient that the above conditions are satisfied on at least one of the left and right sides.

FIG. 6 shows an example of how dust adhering to the filter is removed by rubbing the filter cleaning tool. In FIG. 6, the dust 15 is exaggerated and displayed larger than the actual size ratio for convenience of description. The dust 15 attached to the filter 7 moves when the filter 7 is sent. As a result, at least a part of the dust 15 comes into contact with the filter cleaning tool 10b, falls off the filter 7, and falls.

In the blower device 102, the drive unit 8b can move the filter 7 toward the first side 93 which is one side in the second direction 92, and the filter cleaning tool 10b has a lower end at a lower end than a upper end. It is arranged so as to be located closer to the first side 93. In this state, the blower device 102 includes a dust receiving portion 11b below the filter cleaning tool 10b for receiving the dust 15 falling from the filter 7 or the filter cleaning tool 10b. Since the filter cleaning tool 10b is arranged so as to be inclined, it is possible to avoid the possibility that the dust 15 that has fallen off the filter 7 by the upper part of the filter cleaning tool 10b is caught in the lower part of the filter cleaning tool 10b.

The dust receiving portion is preferably held so that it can be pulled out. By adopting this configuration, the dust accumulated in the dust receiving portion can be easily discharged. For example, as shown in FIG. 7, the dust receiving portion 11a may be held so that it can be pulled out.

(Embodiment 3)
(Constitution)
An air blower according to the third embodiment of the present invention will be described with reference to FIGS. 8 to 9. FIG. 8 shows a schematic configuration of the blower device 103 in the present embodiment.

Blower 103 has the same basic configuration as blower 101 shown in the first embodiment, but differs in the following points.

The driving units 8a and 8b can move the filter 7 toward the first side 93. The state at this time is shown in FIG. The filter cleaning tool 10b is in contact with the filter 7, and the filter cleaning tool 10a is separated from the filter.

FIG. 9 shows a state in which the filter 7 is moved in the opposite direction toward the second side 94. The postures of the front plate 2 are changed by the action of the switching portions 13a and 13b, and the postures of the filter cleaning tools 10a and 10b are also changed accordingly. The filter cleaning tool 10a is in contact with the filter 7, and the filter cleaning tool 10b is separated from the filter.

In the blower device 103, the driving units 8a and 8b can move the filter 7 toward the second side 94 opposite to the first side 93. The blower device 103 includes switching parts 13a and 13b for separating the filter cleaning tool 10b from the surface of the filter 7 when the filter 7 is moved toward the second side 94.

The switching portions 13a and 13b may also serve as the front plate support portions 12a and 12b.
(Action/effect)
In the present embodiment, the filter cleaning tool, which is held in a tilted posture that is inappropriate to abut on the filter 7 in accordance with the moving direction of the filter 7, should be separated from the surface of the filter 7. You can Particularly, when a plurality of filter cleaning tools are provided, only the filter cleaning tool, which is suitable to be brought into contact with the surface of the filter 7 depending on the moving direction of the filter 7, is selectively applied to the surface of the filter 7. This is convenient because the filter cleaning tool that is not in contact with the filter 7 can be separated from the surface of the filter 7 while being in contact with it.

As in any of the blowers 101 to 103, the blower is preferably an air purifier. While it is highly possible that dust will collect in the filter of the air passage port if it continues to be used as an air purifier, any of the embodiments described so far can remove dust efficiently from the filter. The machine can be used in good condition.

In the air blower shown in the embodiment so far, the positional relationship among the filter 7, the drive units 8a and 8b, the filter cleaning tools 10a and 10b, and the intake port 3 is shown in FIG. The filter cleaning tools 10a and 10b are arranged symmetrically so as to sandwich the intake port 3. Since the filter 7 is not endless, it is necessary to move the filter 7 in the opposite direction after it has been moved by the driving portions 8a and 8b in the fixed direction by the fixed length. This is just an example. From here, some modifications will be shown.

For example, as shown in FIG. 11, the filter cleaning tool may be provided only on one side of the intake port 3. In the example shown in FIG. 11, only the filter cleaning tool 10b is provided.

For example, as shown in FIG. 12, a plurality of filter cleaning tools may be arranged on one side of the intake port 3. Here, the filter cleaning tools 10a and 10b are arranged side by side on one side of the intake port 3 in a posture inclined to the same side. That is, the filter cleaning tools 10a and 10b are arranged in parallel on one side of the intake port 3.

Alternatively, the filter cleaning tools 10a and 10b may be arranged so as to sandwich the intake port 3 in a posture inclined to the same side. That is, the filter cleaning tools 10a and 10b may be arranged side by side in parallel with each other with the intake port 3 interposed therebetween.

For example, as shown in FIG. 13, the blower may include an endless filter 7i. In the example shown here, only the filter cleaning tool 10b is arranged, but a plurality of filter cleaning tools may be provided along the endless filter 7i. A plurality of filter cleaning tools may be arranged so as to sandwich the intake port 3, or a plurality of filter cleaning tools may be arranged on one side of the intake port 3.

For example, as shown in FIG. 14, an endless filter 7j may be provided. In addition to the drive units 8a and 8b, two auxiliary rollers 9 are arranged on the rear side. The filter 7j is sent along a trajectory that is substantially rectangular when viewed from above.

For example, as shown in FIG. 15, a filter 7k may be provided. In this example, the drive units 8a, 8 are arranged at the rear, and two auxiliary rollers 14 are arranged at the front. The filter 7j is sent along a locus having a shape corresponding to three of the four sides of the rectangle when viewed from above. The filter cleaning tool 10b is arranged so that the side surface thereof contacts the filter 7k. Although not visible in FIG. 15, the filter cleaning tool 10a may be similarly arranged on the opposite side surface.

It should be noted that a plurality of the above-mentioned embodiments may be appropriately combined and adopted.
It should be noted that the above-described embodiment disclosed this time is an example in all respects, and is not restrictive. The scope of the present invention is defined by the claims, and includes meanings equivalent to the claims and all modifications within the scope.
