Dust collected from the air adheres to the filter installed in the air conditioner for railway vehicles. If the amount of accumulated dust increases, the passage of air deteriorates and air conditioning efficiency decreases. For this reason, the conventional dust remover automatically rolls up the roll filter to supply a new surface, so that the filtering ability of the filter is not lowered transiently, thereby extending the maintenance. However, since the filter finishes winding in about half a year, it requires labor for removing, cleaning, rewinding and maintaining the filter, and it is a problem to prolong the period until further filter maintenance.

In the technique of Patent Document 1, an object attached to the filter is removed by a pair of brushes that are opposed to each other with the filter interposed therebetween. However, since the filter and the brush are in contact with each other at a point, the object is scraped by the brush. The chamfer was substantially small and not efficient.

The present invention was made to solve the above-described problems, and an object of the present invention is to obtain a dust removing device for an air conditioner that can efficiently remove dust accumulated on a filter and prolong the period until maintenance. To do.

A decorative panel 3 is disposed so as to be spaced downward from the ceiling 2 of the vehicle 1, and the ceiling intake port 2 a and the ceiling exhaust port 2 b are formed in positions hidden behind the decorative panel 3 and invisible to the passengers.

The decorative panel 3 is formed with an in-vehicle intake port 3a communicating with the ceiling intake port 2a, an in-vehicle exhaust port 3b communicating with the ceiling exhaust port 2b, and an in-vehicle auxiliary exhaust port 3c communicating with the ceiling exhaust port 2b. . The vehicle intake ports 3a are arranged at two locations in the length direction of the vehicle 1 at each of both end portions in the width direction of the vehicle 1, and here, a total of four locations are formed. In addition, a plurality of in-vehicle exhaust ports 3b are formed at the center in the width direction of the vehicle 1 at intervals in the vehicle length direction. The in-vehicle auxiliary exhaust port 3c is formed at two locations on both sides of the in-vehicle exhaust port 3b in the vehicle width direction so as to extend in the vehicle length direction.

As shown by the arrows in FIG. 3, the vehicle air conditioner 10 sucks air in the vehicle 1 from the air intake port of the vehicle air conditioner 10 through the vehicle intake port 3a and the ceiling air intake port 2a. Air is discharged into the vehicle 1 through the ceiling exhaust port 2b, the vehicle interior exhaust port 3b, and the vehicle interior auxiliary exhaust port 3c. The vehicle air conditioner 10 performs air conditioning in the vehicle 1 while circulating the air in the vehicle 1 in this way.

Further, a control device 11 of the vehicle air conditioner 10 is disposed on the ceiling 2 side of the decorative panel 3. The control device 11 is configured by, for example, a microcomputer, and controls the entire vehicle air conditioner 10 and also performs drive control of the dust removing device 20. The control device 11 has a time measuring unit that measures the operation time of the vehicle air conditioner 10 and holds the operation integration time, and a counter that detects and counts the number of winding operations of the filter 22 described later. .

Further, in the air path from the vehicle interior air inlet 3a to the ceiling air inlet 2a, dust is filtered and collected from the intake air directed to the air inlet of the vehicle air conditioner 10, and clean air is collected into the vehicle air conditioner.

On the vehicle 1 side of the ceiling 2, there are mounting frames 12 in which two openings 12 a are formed in the vehicle length direction corresponding to the in-vehicle intake port 3 a through which the air toward the intake port of the vehicle air conditioner 10 passes. Two pieces are fixed at both ends in the vehicle width direction. A dust removing device 20 is detachably attached to each of the attachment frames 12 corresponding to the openings 12a.

FIG. 4 is an enlarged schematic cross-sectional view of the dust removing device of FIG. 1, and corresponds to a BB cross section of FIG. FIG. 5 is a plan view of FIG.
The dust removing device 20 includes an endless belt-like mesh-type filter 22 made of, for example, saran material, a motor 23 as a driving unit that rotationally drives the filter 22, and a housing 21 having an intake port 20a and an exhaust port 20b. A dust removing mechanism 30 for removing dust adhering to the filter 22 and a deodorizing filter 40 are provided.

The filter 22 is stretched between a drive shaft 24 driven by a motor 23 and a driven shaft 25 driven and rotated by the drive shaft 24. When the drive shaft 24 is rotated by the motor 23, the filter 22 rotates. Accordingly, it rotates in the direction of the solid arrow in FIG. The motor 23 is electrically connected to the control device 11 (see FIG. 1) of the vehicle air conditioner 10 and is driven and controlled by the control device 11. Further, the rotation detector 13 for detecting whether or not the driven shaft 25 has rotated a predetermined amount is attached to the driven shaft 25. The rotation detector 13 outputs a signal while the driven shaft 25 performs a predetermined amount of rotation, and stops the signal output when the predetermined amount of rotation ends. The control device 11 stops the rotation of the motor 23 in response to the fact that the signal from the rotation detector 13 cannot be obtained.

The air inside the vehicle passes through the filter 22 in the direction indicated by the dotted arrow in FIG. 4, and the filter 22 rotates in the direction of the solid arrow in FIG. 4 orthogonal to the passing direction. One surface on the upstream side of the filter 22 is a filtration region surface 22a that filters and collects dust from the in-vehicle air flowing in from the intake port 20a. The filtration region surface 22a is configured to substantially match the opening area of the intake port 20a. A dust removing mechanism 30 for removing dust adhering to the filtration region surface 22a is disposed on the other surface (cleaning surface) 22b side of the downstream side of the filter 22. The dust removing mechanism 30 removes dust attached to the filter 22 when the filter 22 passes through the dust removing mechanism 30, and the configuration thereof will be described below.

FIG. 6 is an enlarged schematic cross-sectional view of a gear mechanism portion in the dust removing mechanism of FIG. FIG. 7 is an enlarged schematic cross-sectional view of the outer brush and the inner brush portion in the dust removing mechanism of FIG. FIG. 8 is an enlarged cross-sectional view of the vicinity of the outer brush portion of FIG. FIG. 9 is a schematic plan view of FIG.

The dust removing mechanism 30 includes an outer brush 31 and an inner brush 32 for removing dust accumulated on the filter 22 from the filter 22. The outer brush 31 is disposed to face the front surface side of the filter 22, and the inner brush 32 is disposed to face the rear surface side of the filter 22.

The outer brush 31 and the inner brush 32 rotate in conjunction with the rotation of the drive shaft 24 by a gear mechanism. That is, a gear 31a connected to the gear 24a of the drive shaft 24 is provided at one end of the shaft of the outer brush 31 over the entire circumference. Further, a gear 32a connected to the gear 31a of the outer brush 31 is provided at one end of the shaft of the inner brush 32 over the entire circumference. By this gear mechanism, the outer brush 31 and the inner brush 32 rotate in the same direction as the movement direction of the filter 22 in conjunction with the rotation of the drive shaft 24. Note that the rotation of the drive shaft 24 is transmitted to the outer brush 31 and the inner brush 32 at a reduced speed by this gear mechanism, and rotates to have a relative speed with respect to the filter 22. Due to this relative speed difference, the outer brush 31 and the inner brush 32 collect and remove dust adhering to the filter 22.

Further, the outer brush 31 and the inner brush 32 are arranged so as to be shifted in the moving direction of the filter 22 from positions facing each other with the filter 22 interposed therebetween, and the filter 22 can be moved in a wave-like curved state. Has been placed. With this configuration, compared to the case where the outer brush 31 and the inner brush 32 are arranged so as to face each other with the filter 22 in between, the contact surface in contact with the filter 22 can be widened, and dust can be efficiently removed. It has become.

The dust removing mechanism 30 further includes an outer scraping plate 34 that contacts the surface of the outer brush 31 and scrapes dust adhering to the outer brush 31, and a detachable mechanism that collects dust scraped by the outer scraping plate 34. And an outer collection BOX 33. As shown in FIG. 9, the outer scraping plate 34 is formed with a plurality of chevron-shaped tips on the side in contact with the outer brush 31, and when the outer brush 31 rotates, the chevron-shaped tip becomes an outer brush. Dust adhering to the outer brush 31 in contact with the surface of 31 is scraped off, and the scraped dust is collected in the outer collection BOX 33. By forming the tip of the outer scraping plate 34 on the side in contact with the outer brush 31 into a plurality of mountain shapes, dust can be efficiently scraped off.

Further, the dust removing mechanism 30 has the same configuration on the inner brush 32 side as that on the outer brush 31 side. That is, an inner scraping plate 36 that contacts the surface of the inner brush 32 and scrapes dust adhering to the inner brush 32, and a removable inner collection BOX 35 that collects dust scraped off by the inner scraping plate 36. I have. The inner scraping plate 36 has a plurality of chevron-shaped tips on the side in contact with the inner brush 32, and when the inner brush 32 rotates, the chevron-shaped tip reaches the surface of the inner brush 32. Dust that contacts and adheres to the inner brush 32 is scraped off, and the scraped dust is collected in the inner collection BOX 35. By forming the tip of the inner scraping plate 36 on the side in contact with the inner brush 32 into a plurality of mountain shapes, dust can be efficiently scraped off.

The outer collection BOX 33 and the inner collection BOX 35 are made of a material such as a transparent or translucent resin so that dust accumulated inside can be easily seen. The material of the outer collection BOX 33 and the inner collection BOX 35 may be made of metal in consideration of durability against vehicle vibration and the ease of production by sheet metal processing in addition to resin. In this case as well, it is preferable that at least a part is made transparent or translucent so that dust accumulated inside can be easily seen. In addition, antibacterial treatment is performed on the inner surfaces of the outer collection BOX 33 and the inner collection BOX 35.

The deodorizing filter 40 is composed of, for example, a manganese oxide-based catalyst filter, and is disposed between the exhaust port 20b of the housing 21 and the filter 22 before being sucked into the intake port of the vehicle air conditioner 10. Remove odors from intake air. As shown in FIGS. 4 and 5, the deodorizing filter 40 is formed in a size that covers a surface corresponding to substantially half of the filtration region surface 22 a of the filter 22. If the entire filtration region surface 22a is covered with the deodorizing filter 40, the air permeability is deteriorated. Therefore, the surface corresponding to approximately half is covered here. Thereby, it is possible to obtain both the dust removing ability and the odor removing effect.

Next, the operation of the present embodiment will be described.
When the vehicle air conditioner 10 is driven by the control device 11, the air in the vehicle 1 is taken into the vehicle air conditioner 10 through the vehicle inlet 3a, the dust remover 20, and the ceiling inlet 2a. At this time, dust contained in the vehicle interior air is removed by the dust removing device 20, and clean air flows into the vehicle air conditioner 10. And after discharging | emitting from the air conditioning apparatus 10 for vehicles, it blows off in the vehicle 1 through the ceiling exhaust port 2b and the vehicle interior exhaust port 3b.

In the dust removing device 20, the in-vehicle air that has flowed into the housing 21 from the air inlet 20 a first passes through the filtration region surface 22 a of the filter 22. Dust in the vehicle interior air is filtered through the filtration region surface 22a to become clean air, and then passes through the deodorizing filter 40 to remove odors and then discharged from the exhaust port 20b toward the vehicle air conditioner 10. The As described above, the air in the vehicle circulates through the dust removing device 20, the vehicle air conditioner 10, and the vehicle 1, so that dust gradually accumulates on the filtration region surface 22a.

After starting the operation of the vehicle air conditioner 10, the control device 11 measures the operation time of the vehicle air conditioner 10 by the time measuring unit, and the operation integrated time measured by the time measuring unit is set to a predetermined integrated time set in advance. When (for example, 20 hours) is reached, a drive command is issued to the motor 23.

When a drive command is issued from the control device 11, the motor 23 rotates the drive shaft 24 a predetermined number of times. Specifically, after outputting the drive command, the control device 11 rotates the drive shaft 24 only while the signal from the rotation detector 13 provided on the driven shaft 25 returns. As a result, the filter 22 is fed by a predetermined amount, the filtration region surface 22a passes through the dust removal mechanism 30, and the dust adhering to the filtration region surface 22a is removed to become the dust removed surface 22b. The dust-removed surface 22b that has been positioned moves to the upstream side and is reused as a new filtration region surface 22a.

The dust removal operation by the dust removal mechanism 30 is as described above. When the drive shaft 24 is rotated by a drive command from the control device 11, the outer brush 31 and the inner brush 32 move the filter 22 as the drive shaft 24 rotates. And rotate to have a relative speed in the same direction. Thereby, each of the outer brush 31 and the inner brush 32 removes dust adhering to the surface side and inner surface side of the filter 22 from the filter 22.

Then, the dust removed from the filter 22 and attached to the outer brush 31 is scraped off by the outer scraping plate 34 and collected in the outer collecting BOX 33. The same applies to the inner brush 32, and dust attached to the inner brush 32 is scraped off by the inner scraping plate 36 and collected in the inner collection BOX 35.

And, when throwing away the dust accumulated in the outer collection BOX 33 and the inner collection BOX 35, the inlet cover 3d of the decorative panel 3 is opened, the outer collection BOX 33 and the inner collection BOX 35 are removed, and the dust inside is discarded.

Here, the removal operation of the outer collection BOX 33 and the inner collection BOX 35 will be briefly described with reference to the drawings.
10 and 11 are explanatory diagrams of the removal operation of the outer collection BOX and the inner collection BOX. 10 and FIG. 11 correspond to enlarged views of a dotted circle portion in FIG. 10 and 11 corresponds to the view seen from the direction of the white arrow A in FIG. 4, and the filter 22 is stretched in a direction perpendicular to the paper surface in FIGS. It has become.

As shown in FIGS. 10 and 11, the dust removing device 20 is provided at a position that can be accessed immediately after opening the intake cover 3 d that opens and closes the in-vehicle intake 3 a of the decorative panel 3. In the state in which the air inlet cover 3d is opened, the end faces of the outer collection BOX 33 and the inner collection BOX 35 are visible from the direction of the white arrows in FIG. 10, and dust is contained in the outer collection BOX 33 and the inner collection BOX 35. It is possible to check whether or not there is any accumulation. Further, the dust removing device 20 is attached to the mounting frame 12 so as to be rotatable in the direction of the solid line arrow in FIG. 11. As shown in FIG. 11, the dust removing device 20 is rotated so that the outer collection BOX 33 and the inner collection BOX 35 are shown in FIG. By pulling out in the direction indicated by the arrow, it is possible to discard the dust accumulated inside.

As described above, the dust removing device 20 rotates the filter 22 every specified integration time, and automatically cleans the filtration region surface 22a by the dust removal mechanism 30, while the dust-removed surface 22b is re-used as a new filtration region surface 22a. Repeat the action you want to use. Each time the filter winding operation is performed once, the counter of the control device 11 counts the number of operations by adding one. When this count reaches the set number of times (the number of winding operation limit times corresponding to the life of one filter 22), the control device 11 turns on an indicator lamp (not shown) that prompts replacement of the dust removing device 20, and Stop automatic operation.

As described above, in the present embodiment, the dust attached to the filter 22 is automatically removed by the dust removing mechanism 30, so that the dust removal device 20 can be filtered without performing a complicated cleaning operation of the filter 22. Capability can be kept in good condition.

In addition, the outer brush 31 and the inner brush 32 are arranged so as to be shifted in the moving direction of the filter 22 from positions facing each other with the filter 22 interposed therebetween, and are arranged so that the filter 22 can be moved in a wave-like curved state. ing. With this configuration, it is possible to make a wider contact surface in contact with the filter 22 than when the outer brush 31 and the inner brush 32 are arranged to face each other with the filter 22 interposed therebetween. Therefore, the dust adhering to the filter 22 can be efficiently removed.

Further, the filter 22 is moved by a predetermined amount, and the filtration area surface 22a on which dust is accumulated passes through the dust removal mechanism 30 to be the dust removed surface 22b, while the dust removed surface 22b on the downstream side of the filter 22 is the upstream side. And is reused as a new filtration area surface 22a. This eliminates the need for cleaning the filter 22 for a long period of time and reduces the work required to replace the filter 22. In addition, since the circulating air in the vehicle can always be removed by the clean surface from which dust has been removed, there is an effect that clean air can be always supplied into the vehicle 1.

In addition, the dust removal device 20 does not need complicated cleaning, and the filter 22 can be automatically wound and replaced as long as a predetermined integration time is set in advance. It can be significantly improved.

Further, if the filter 22 continues to be used while dust is accumulated, the pressure loss increases and the air volume decreases and the performance of the air conditioner deteriorates. However, in this example, when a predetermined integrated integration time is reached. Since the filter 22 is rotated and the dust-removed clean surface becomes a new filtration region surface 22a, such inconvenience can be solved.

The specified integration time can be set and changed according to the air environment inside the vehicle, and is set according to the speed of dust accumulation on the filter 22 so that the filter 22 is always at an appropriate timing in any vehicle 1. Can be rotated. Therefore, for example, even in the case of the vehicle 1 in which the dust accumulation speed of the filter 22 is fast, if the optimum driving cycle (specified integration time) is set according to the traveling speed, the filtering capacity becomes undesired. It is possible to drive well without deteriorating.

Further, when the number of winding operations of the filter 22 reaches the number of times of limiting the winding operation corresponding to the life of the filter 22, a message prompting the replacement of the dust removing device 20 is displayed and the automatic operation is stopped. Therefore, the functionality of the dust removing device 20 can be maintained.

Further, since the odor is removed from the air in the vehicle by the deodorizing filter 40 and clean air is supplied into the vehicle, a comfortable in-vehicle air environment can be provided. Further, since the deodorizing filter 40 is provided in the air passage after passing through the filter 22, odor removal can be performed more efficiently than in the case where it is provided in the air passage before passing through the filter 22.

Moreover, since the antibacterial treatment is applied to the inner surfaces of the outer collection BOX 33 and the inner collection BOX 35, it is possible to prevent the propagation of germs and is hygienic.

In the present embodiment, an example is shown in which control is performed to stop the drive shaft 24 by rotating the drive shaft 24 by a predetermined number of revolutions based on a signal from the rotation detector 13 that detects the rotation of the driven shaft 25. However, the present invention is limited to this. It is not a thing. For example, the motor 23 may be driven for a preset time without using the rotation detector 13 so that the number of rotations of the drive shaft 24 becomes a desired number.

Note that the air conditioner 10 referred to in the present embodiment includes, for example, an air circulator such as a blower that simply circulates air, in addition to a device that performs temperature adjustment such as heating and cooling, and a device that performs dehumidification.
