Description

The present invention relates to an air conditioner equipped with a filter cleaning device.

Conventionally, this type of air conditioner has been equipped with a filter cleaning device that uses a brush to remove dust adhering to the air filter, and also uses a blade to scrape off the dust adhering to the brush into a dust storage section below the brush. . Among such filter cleaning devices, there is one in which an exhaust device is connected to the dust storage section to suction and exhaust the dust collected in the dust storage section to the outside (for example, Patent Document (see 1).

14 and 15 show the configuration of a filter cleaning device in an air conditioner described in Patent Document 1 above. 14 and 15, 100 is an air filter provided at the suction port of the harmonizer body, 101 is a brush for removing dust attached to the air filter 100, and 102 is a brush holding stand on which the brush 101 is installed. , it can be reversed to a downward facing position. A blade 103 is located below the brush holder 102 and scrapes off dust from the brush 101 of the brush holder 102 which has been turned downward. Reference numeral 104 denotes a dust receiving part that holds the blade 103 and receives the dust scraped off by the blade 103, and this dust receiving part 104 can also be turned over to a downward position. Reference numeral 105 indicates a dust storage section disposed further below the dust receiving section 104, and reference numeral 106 indicates a discharge device for discharging the dust collected in the dust storage section 105 by airflow.

In the above configuration, the dust adhering to the air filter 100 is scraped off by the brush 101 by sliding the air filter 100 against the brush 101 as shown by the arrow Z, and collected in the dust storage section 105. It is dropped onto the dust receiving section 104. After stopping the air filter drive, the brush holding stand 102 is reversed downward as shown by the arrow W, so that the brush 101 is placed in a downward position. In this state, the brush 101 of the brush holding stand 102 is swung to scrape off the dust adhering to the brush 101, and the dust is dropped onto the dust receiver 104 holding the blade 103 and collected.

Thereafter, the dust receiving section 104 is rotated from the upward position to the downward position, and the dust accumulated in the dust receiving section 104 is dropped into the dust storage section 105 and collected. A cylindrical discharge passage 105a is formed covering the opening portion, and the discharge device 106 is operated. Due to the operation of the discharge device 106, the dust collected in the dust storage section 105 is discharged to the outside.

Therefore, the dust collected in the dust storage section 105 can be discharged by driving the discharge device 106 without removing the dust storage section 105 from the air conditioner main body, and the trouble of dust disposal can be saved.

Japanese Patent Application Publication No. 2017-110860

However, according to the configuration of Patent Document 1, the dust removed from the brush 101 falls and is collected over almost the entire length of the dust storage section 105, and the dust on the side of the discharge device 106 of the dust storage section 105 is well sucked. Although it can be discharged, there is a problem in that it takes time to suction and discharge the dust near the end opposite to the discharge device 106.

In detail, since the upper opening of the dust storage section 105 that collects the dust removed from the brush 101 is closed by reversing the dust receiving section 104, the dust receiving section 104 and the upper opening of the dust storage section 105 are closed. Air will also be sucked in through the gaps created between the parts. Therefore, the amount of air sucked from the end opening provided on the opposite side of the dust storage section 105 from the discharge device 106 is reduced, and the dust removed from the brush 101 is spread over almost the entire length of the dust storage section 105 in the longitudinal direction. If the filters are scattered, it takes time to suction and discharge the dust near the opposite side of the discharge device 106, and the filter cleaning time becomes long.

Furthermore, this filter cleaning device swings the brush 101 on the brush holder 102 to scrape off the dust attached to the brush 101, but at this time, a crackling sound is generated, which may be alarming to the user. There was also the issue of creating a sense of distrust.

The present invention has solved these problems, and aims to provide an air conditioner that can quickly and quietly discharge the dust in the dust storage section, and at the same time eliminate the possibility of failure to collect dust, thereby improving quality and reliability. This is the purpose.

In order to achieve the above object, the present invention provides a filter cleaning device that includes an air filter built into a harmonizer main body, a dust removal brush arranged along the longitudinal direction of the air filter, and a dust removal brush disposed below the brush. a dust storage section that stores the dust that has been located and removed; a dust removal member that moves inside the dust storage section to remove the dust inside the dust storage section; and a dust removal member that moves the dust stored in the dust storage section outside. and a discharge device for suctioning and discharging the dust, and the dust storage section includes a first dust storage section provided below the brush, and a second dust storage section located below the first dust storage section. , the second dust storage section is connected to the discharge device and has a dust discharge port for sucking air inside the dust storage section, and further includes a connection between the first dust storage section and the second dust storage section. A first opening is provided in the discharge device side part, and a second opening is provided in the end opposite to the discharge device, and the dust removing member is arranged in the first dust storage section of the dust storage section. This is the configuration that is included in the section.

As a result, the dust is collected by the dust removal member toward the first opening or the second opening provided between the first dust storage section and the second dust storage section, and the dust is collected from the first or second opening side to the second opening side. It will be taken into the dust storage section. Therefore, the dust can be suctioned and discharged all at once by the exhaust device.

Furthermore, when the dust removal member is moved to scrape up dust, some of the dust may fall off in the direction opposite to the movement direction of the dust removal member. By moving the dust removing member in the opposite direction, that is, returning the dust removing member, the spilled dust can also be collected and taken into the second dust storage section from the second opening or the first opening. Since the amount of dust taken into the second dust storage section is very small, it can be easily and quickly sucked in by the exhaust device and discharged to the outside.

As described above, the dust removed by the brush can be collected and discharged cleanly without leaving any residue behind.

The present invention eliminates failure to collect dust, etc., and can greatly improve the quality and reliability of air conditioners.

A first invention includes an air filter built into a harmonizer main body, a dust removal brush arranged along the longitudinal direction of the air filter, and a dust removal brush located below the brush to accommodate the removed dust. The dust removing member includes a storage section, a dust removal member that moves inside the dust storage section to remove dust inside the dust storage section, and a discharge device that sucks and discharges the dust stored in the dust storage section to the outside. , the dust storage section includes a first dust storage section provided below the brush, and a second dust storage section located below the first dust storage section; It has a dust exhaust port that is connected to the exhaust device and sucks the air inside the dust storage section, and further includes a part on the side of the exhaust device between the first dust storage section and the second dust storage section. A first opening is provided at the end thereof, and a second opening is provided at an end opposite to the discharge device, and the dust removing member is provided in the first dust storage section of the dust storage section.

As a result, the dust is collected by the dust removal member toward the first opening or the second opening provided between the first dust storage section and the second dust storage section, and the dust is collected from the first or second opening side to the second opening side. It will be taken into the dust storage section. Therefore, the dust can be suctioned and discharged at once by the exhaust device.

Furthermore, when the dust removal member is moved to scrape up dust, some of the dust may fall off in the direction opposite to the movement direction of the dust removal member. By moving the dust removing member in the opposite direction, that is, returning the dust removing member, the spilled dust can also be collected and taken into the second dust storage section from the second opening or the first opening. Since the amount of dust taken into the second dust storage section is very small, it can be easily and quickly sucked in by the exhaust device and discharged to the outside.

As described above, the dust removed by the brush can be collected and discharged cleanly without leaving any residue behind.

In a second invention, in the first invention, the second dust storage section is configured such that the portions other than the first opening, the second opening, and the dust outlet are in a substantially sealed state.

Thereby, the dust taken into the vicinity of the second opening at the end of the second dust storage section can be efficiently sucked and discharged even if the dust is far away from the discharge device, and the cleaning time can be more effectively shortened.

In a third aspect of the present invention, in the first or second aspect, the dust removing member is configured to be slidable in the longitudinal direction of the brush to remove dust attached to the brush.

As a result, when removing dust from the brush, the dust removing member moves along the brush, so there is no buzzing noise as in the conventional case, and the filter can be cleaned more quietly.

A fourth invention is based on the first to third inventions, wherein the dust removal member has a structure in which upper surfaces on both sides of the dust removal part in contact with the brush are downwardly inclined surfaces.

This prevents the dust scraped from the brush by the dust removal member from remaining on the top surface of the dust removal member, and ensures that the dust removed from the first opening or the second opening is not left behind. It can be collected and discharged into the dust storage section.

A fifth invention is based on the first to fourth inventions, wherein the sliding movement of the dust removing member is configured such that the sliding movement ends on the first opening side.

As a result, the dust is collected in a concentrated manner near the exhaust device, so that it can be suctioned and discharged all at once by the exhaust device, making it possible to more effectively shorten the cleaning time.

A sixth invention is based on the first to fifth inventions, wherein the dust storage section is configured such that the second dust storage section is detachable.

This allows you to manually dispose of the dust inside by removing the dust storage unit, and depending on the conditions of the building where the air conditioner is installed, you can either automatically discharge the dust using the exhaust device or manually dispose of the dust by attaching and detaching the dust storage unit. It can be used in two ways, improving convenience.

The brush 16 is attached and held by a brush holder 17, which is an example of a brush rotating device, and a gutter-shaped dust storage section 18 is provided below the brush holder 17.

As shown in FIGS. 6 to 8, the brush holding stand 17 is integrally formed with a large number of reinforcing ribs 19 that intersect with the longitudinal direction on a surface different from the surface that holds the brush 16, and is provided on one end side of the reinforcing ribs 19. A drive unit (not shown) such as a motor rotates the tip of the brush 16 into a position where it contacts the air filter 10 and a position where the tip of the brush 16 that was in contact with the air filter 10 does not come into contact with the air filter. It is now possible to do so. Note that the shape of the brush 16 may be, for example, a roller-shaped brush other than the configuration of the first embodiment.

Further, as shown in FIGS. 4 to 6, the dust storage section 18 has two stages: a first dust storage section 18A that is open at the top, and a second dust storage section 18B that is provided at the bottom of the first dust storage section 18A. The structure is as follows. The second dust storage section 18B may be detachable from the main body 2. A dust removal member 21 (hereinafter referred to as a blade) for moving dust inside the dust storage section is provided inside the first dust storage section 18A. Note that the blade 21 may be configured to remove dust attached to the brush 16.

The blade 21 is slidably provided in the longitudinal direction of the brush 16, and is connected to a driving means 22 such as a motor provided at one end of the dust storage section 18, as shown in FIGS. 7 and 8. It is configured to be driven via a connecting means (not shown) such as a belt or wire, and slides in contact with the brush 16 which is in a position where it does not come into contact with the air filter, and removes dust attached to the brush 16. Scrape off.

The blade 21 is made of an elastic material such as rubber, preferably a flexible soft elastic material, and has a triangular cross section with the scraping portion 21a in contact with the brush 16 as the apex, as shown in FIG. The upper surfaces thereof are inclined surfaces 21b and 21c.

Further, as shown in FIG. 8, a first opening 23 is provided on the side of the discharge device in the partition wall portion 18C that partitions the first dust storage portion 18A and the second dust storage portion 18B. A second opening 24 is formed at the opposite end. The second dust storage section 18B is provided with a dust discharge port 25 facing the first opening 23 of the first dust storage section 18A, and a fan sucks and exhausts dust through the dust discharge port 25. A discharge device 26 (see FIG. 7) such as the like is connected.

The second dust storage section 18B has a structure in which the portions other than the first opening 23, the second opening 24, and the dust outlet 25 are substantially sealed, and the portion facing the second opening 24 is sloped. A section 27 is provided.

Further, the brush 16, the brush holder 17, the blade 21, and the dust storage section 18 constitute a dust collection unit A, as shown in FIG. The devices 26 are connected to form a dust collection and discharge unit B shown in FIG.

Further, a filter drive device 20 (see FIG. 6) such as a motor that drives the gear 14 of the filter conveying device 12 is arranged near the connection portion between the dust collection unit A of the dust collection and discharge unit B and the discharge device 26. has been done.

An example of an operation for cleaning and discharging dust attached to the air filter 10 of the air conditioner configured as described above will be described below.

When the air conditioner is used for a predetermined period of time and a filter cleaning start signal is issued, the brush holder 17 is reversed and the brush 16 comes into contact with the air filter 10 as shown in FIG. 10(a). Thereafter, the filter drive device 20 operates, the gear 14 of the filter conveyance device 12 is rotated in the forward direction, and the air filter 10 is conveyed from the first holding space 11a to the second holding space 11b.

During this transportation, the brush holder 17 is fixed at a position where the brush 16 contacts the air filter 10, and the dust attached to the air filter 10 is blocked and removed by the brush 16 fixed at a fixed position. be done.

Here, the brush 16 is compressed by contact with the air filter 10, but since the brush holder 17 that holds the brush 16 is reinforced by the reinforcing ribs 19, it will not be bent or deformed. Therefore, the efficiency of removing dust attached to the air filter 10 is improved.

When the gear 14 is further rotated in the forward direction and the air filter 10 reaches the end of the second holding space 11b, the forward rotation of the gear 14 is stopped and the brush 16 is placed in a standby position where it does not come into contact with the air filter 10. 14 and return the air filter 10 to its original position.

Repeat the above operation several times if necessary to complete filter cleaning.

After the filter cleaning is completed, a dust discharge operation is performed next. This will be explained below using FIG. 10(b), FIG. 11, FIG. 12, and FIG. 13.

When the cleaning operation of the air filter 10 is completed, the brush holder 17 is rotated in the opposite direction, and the brush 16 is reversed to the brush cleaning position, that is, a posture in which it does not come into contact with the air filter, as shown in FIGS. 10(b) and 11. and faces the inside of the first dust storage section 18A.

Thereafter, the driving means 22 of the blade 21 is driven, and the blade 21 is slid along the longitudinal direction of the brush 16 from the one end side shown in FIG. 13(a).

As a result, the blade 21 scrapes off the dust adhering to the brush 16, and conveys the scraped dust toward the first opening 23 so that the sliding end is on the discharge device 26 side, as shown in FIG. .

When the dust transported toward the first opening 23 reaches the end of the first dust storage section 18A shown in FIGS. 12(a) and 13(b), the discharge device 26 is driven and the The blade 21 continues to slide and closes the first opening 23 as shown in FIGS. 12(b) and 13(c).

Thereby, the dust group X conveyed by the blade 21 is sucked into the discharge device 26 through the first opening 23 and the dust discharge port 25, and is discharged outdoors as it is.

That is, in the dust discharge configuration of this embodiment, the dust group X scraped off from the brush 16 is collected in one place by the blade 21, in this example, on the discharge device 26 side of the second dust storage section 18B, and the dust group The dust collected on the discharge device 26 side of the section 18B is sucked and discharged outdoors.

Therefore, dust is efficiently discharged by the discharge device 26, and the driving time of the discharge device 26, that is, the time for suction and discharge of dust can be significantly shortened.

Moreover, the dust that falls on the upper surface of the blade when scraped by the blade 21 slides down along the inclined surface 21b of the blade 21 in the direction of movement of the blade 21. Therefore, the dust does not accumulate on the upper surface of the blade 21 and obstruct the scraping off of the dust by the scraping section 21a, and the dust can be scraped off efficiently.

Furthermore, since the blade 21 slides along the brush 16 when removing dust from the brush 16, there is no buzzing noise as in the conventional case, and the filter can be cleaned more quietly.

On the other hand, when the dust group X scraped off by the blade 21 is conveyed to the first opening 23 side, in the dust discharge configuration of the present embodiment, a part of the scraped dust group is opposite to the traveling direction of the blade 21. It is assumed that the liquid will spill onto the slope 21c side of the screen and remain without being discharged.

However, in the dust discharge configuration of this embodiment, since the second opening 24 is provided at the end opposite to the first opening 23, that is, at the initial position side of the blade 21, the dust is removed through the second opening 24. The spilled dust will also be discharged.

More specifically, when the above-mentioned dust discharge is completed, the discharge device 26 is stopped, and the blade 21 is returned to its initial position via the drive means 22 of the blade 21 as shown in FIG. 13(d). At this time, the blade 21 transports the spilled dust Y to the second opening 24 provided on the opposite side of the first opening 23, as shown in FIG. Immediately before closing, the ejector 26 is activated. Then, the blade 21 moves further and closes the second opening 24 as shown in FIG. 12(d) and FIG. 13(e).

As a result, the dust transported by the blade 21 is sucked into the second dust storage part 18B from the second opening 24, and the dust is sucked into the second dust storage part 18B and the dust discharge port 25 as shown in FIG. 13(f). As in the case described above, the liquid is sucked into the discharge device 26 through the air, and is discharged outdoors as it is.

Therefore, the dust Y spilled when the blade 21 slides can be collected cleanly and reliably discharged outdoors without leaving any residue behind.

In addition, since the amount of dust Y spilled when the blade 21 slides is very small, it is easily and quickly sucked up by the suction by the discharge device 26, and the spilled dust Y is also efficiently discharged.

Further, in the present embodiment, the dust storage section 18 is in a substantially sealed state except for the first opening 23, the second opening 24, and the dust discharge port 25, so that the dust storage section 18 is in a substantially sealed state. The captured dust can be efficiently sucked and discharged even if it is far away from the discharge device 26.

Therefore, the time for discharging the spilled dust can also be shortened, and even if the time for discharging the spilled dust is added, the time for cleaning the air filter 10 and discharging the dust can be significantly shortened.

In the configuration of the first embodiment, when scraping off the dust attached to the brush 16, the blade 21 is slid along the longitudinal direction of the brush 16 to scrape off the dust. As a method for removing the blade, for example, a blade having the same length as the length in the longitudinal direction of the brush 16 is extended parallel to the brush 16, and the brush 16 is swung at a position where it comes into contact with the blade. , a method of removing dust attached to the brush 16 may also be used.

On the other hand, in the dust storage section 18 that stores the dust, the second dust storage section 18B is detachable from the main body 2 in this embodiment. Therefore, in this embodiment, the second dust storage section 18B can be taken out and the dust can be disposed of, improving convenience.

For example, there are buildings in which the dust removed from the filter cannot be automatically sucked and discharged by the exhaust device 26, such as high-rise floors such as high-rise apartment buildings. It can be used by removing it from the machine and disposing of dust. Therefore, convenience is improved.

As above, the air conditioner according to the present invention has been explained using the above embodiments, but the present invention is not limited thereto, and the scope of the present invention is indicated by the claims. It shall include all changes within the meaning and scope equivalent to the scope of.

For example, in this embodiment, an air conditioner is described in which the indoor unit and the outdoor unit are separated, but they may be integrated.

Further, although the second dust storage section 18B is made detachable from the dust storage section 18, it may be formed integrally with the first dust storage section 18A so that it cannot be attached or detached from the main body side.

Furthermore, the ejecting device 26 is driven when the blade 21 comes to the first opening 23 side and when it comes to the second opening 24, but this is because the blade 21 is slid as shown in FIG. 13(a). The device may be driven in the entire area from the time of movement to the area shown in (f) in Figure 13 or in the area from (a) to (f) other than (d) in the same figure. Driving the device 26 is effective in improving the effect of scraping off dust from the brush 16.

As described above, the air conditioner according to the present invention can discharge dust from the filter cleaning device quickly and quietly, and eliminates failure to collect dust, greatly improving the quality and reliability of the air conditioner. can be done. Therefore, it can be applied to various air conditioners including those used in general homes.
