Description

  The present invention relates to an air conditioner, and more particularly to an automatic filter cleaning device that automatically cleans dust on a filter of a ceiling-embedded air conditioner.

  In a conventional ceiling-embedded air conditioner, when the filter is used as a suction port for sucking room air for a long time, dust in the air accumulates in the filter and the filter is clogged. In this state, the amount of air sucked from the suction port is reduced, and sufficient heat exchange cannot be performed by the heat exchanger, causing a phenomenon in which the performance of the air conditioner is lowered. Therefore, it is necessary to periodically remove the filter and remove dust.

Therefore, in order to solve the above-mentioned problems, an apparatus for performing a removing operation by a method such as automatically sucking dust has been devised, and the labor required for the cleaning operation has been greatly reduced.

  However, the conventional ceiling-embedded air conditioner is a mechanism that automatically sucks the dust adhering to the filter or uses a brush and then collects it in the collecting unit. The unit had to be removed and removed. As a result, although the cleaning work of the filter has been greatly reduced as compared with the prior art, the removal work has only been knitted from the filter into the unit, and there still remains a problem that requires a manual removal work.

  The present invention has been made to solve the above-described problems, and has an object of losing the cleaning work of the filter in the air conditioner by automating from dust removal to discharge.

  The ceiling-embedded air conditioner according to the present invention is installed in a ceiling, communicates with an air suction port and a blow-out port that blows into the room to form an air passage, and is installed so as to surround the blower between the air passages. A heat exchanger and a filter that collects dust in the intake air are disposed in a suspended state between the blower and the heat exchanger and along the heat exchanger side.

  The ceiling-embedded air conditioner according to the present invention is installed in a ceiling, communicates with an air suction port and a blow-out port that blows into the room to form an air passage, and is installed so as to surround the blower between the air passages. The heat exchanger and the filter for collecting dust in the intake air are arranged in a suspended state between the blower and the heat exchanger and along the heat exchanger side. It is possible to obtain a ceiling-embedded air conditioner that automates the process from removal of dust to discharge.

Embodiment 1 FIG.

Fig. 6 is an enlarged cross-sectional view showing a dust removing device for an air conditioner, and Fig. 6 is a schematic view showing drain discharge including dust in the ceiling-embedded air conditioner according to Embodiment 1 of the present invention.

In the figure, a ceiling-embedded air conditioner 2 in which a decorative panel 1 having a lower central suction port 1a and a blower port 1b around it is provided on the lower surface surrounds the blower 3 and the blower 3 in the center, and the suction by the blower 3 A heat exchanger 4 having a substantially quadrangular cross section is formed to exchange heat between indoor air sucked from the port 1a and blown out from the outlet 1b. A belt-like filter 5 having a filter end coupled thereto is provided between the blower 3 and the heat exchanger 4, and a tooth hole 5 a having a predetermined pitch is formed in the end in a flexible state. One end of the belt shape is supported by a support roller 5b so as to be along the shape of the heat exchanger 4 side, and a pair of fixed rollers 5c and a tooth hole 5a of the belt-like filter are provided inside the corner portion of the heat exchanger 4. A filter driving device 6 for rotationally driving a gear 6a that moves laterally in a meshing endless manner is provided at the other end portion and is supported in a suspended state by the ceiling-embedded air conditioner. The drain pan 7 is located below the heat exchanger 4. Dust in the room air collected by the filter 5 is removed by a dust removing device 8 attached to the inside of the air conditioner 2. The dust removing device 8 scrapes off dust adhering to the filter 5 by a cleaning brush 8c fixed to the rotary electric motor 8a by a shaft 8b. A watering device provided with a watering nozzle 9a for washing out dust from above the cleaning brush 8c with water so as to collect the dust adhering to the filter 5 to be scraped off by the drain pan 7 positioned below the heat exchanger 4. 9 is provided integrally with the dust removing device 8. The drain pump 10 is generated by the heat exchanger 4 and collected by the heat exchanger 4 and is collected by the water from the water nozzle 9a of the water spraying device 9 provided integrally with the dust removing device 8 on the drain pan 7. It is discharged out of the air conditioner 2 together with the drain water collected in the air.

  In the ceiling-embedded air conditioner according to Embodiment 1 configured as described above, air is sucked from the suction port 1a at the center of the decorative panel 1, and the blower 3, the filter 5, and the heat exchanger 4 inside the air conditioner 2 are connected. It blows out from the blower outlet 1b via. At this time, dust in the air is collected and accumulated in the air filter 5 installed between the suction port 1a and the blowout port 1b. The accumulated dust starts operation of the filter driving device 6, the dust removing device 8, the watering device 9, and the drain pump 10 at almost the same time periodically, and the filter driving device 6 moves the filter 5 endlessly. 8 is scraped off by the rotary cleaning brush 8c, and is simultaneously washed off by the water dripped from the nozzle 9a of the watering device 9 into the cleaning brush 8c and collected in the drain pan 7, and the filter driving device 6 and the dust removing device 8 are cleaned. The drain pump 10 simultaneously rotated together with the brush 8c is discharged out of the air conditioner 2 to finish cleaning.

  With the configuration as described above, the entire surface of the filter can be automatically cleaned cleanly.

  In the ceiling-embedded air conditioner that is another example of the first embodiment, the filter 5 is provided between the blower 3 and the heat exchanger 4, and frictional force is applied to the inner surface side at the end of the filter 5. A rubber-like shape which forms a flexible belt 12 and has a plurality of rubber rollers 13 and the flexible belt 12 of the endless filter so as to be along the heat exchanger 4 side and move laterally endlessly. Is supported in a suspended state by the ceiling-embedded air conditioner.

  Furthermore, in the ceiling-embedded air conditioner according to another example of the first embodiment, the single filter 15 is suspended and supported along the inside of the heat exchanger 4 having a substantially square cross section. On the inner surface side of the single filter 15, a dust removing device 8 that is collected by the single filter 15 and scrapes off dust is slidably supported on a moving rail 16 provided on the top surface 2 a of the main body 2. Since this dust removing device 8 is the same as that of the first embodiment, description thereof is omitted.

  In the ceiling-embedded air conditioner according to another example of the first embodiment, the cleaning brush 8c is started from one end of the filter 15 to slide on the rail 16 while rotating, and the water spraying device 9 sprays water. At the same time, the dust that has been scraped off is collected in the lower drain pan 7. The dust collected in the drain pan 7 is discharged out of the air conditioner main body 2 by the drain pump 10 together with the drain generated in the normal operation.
