Description

  The present invention relates to a filter device for an air conditioner that automatically cleans an air filter.

  In the conventional air conditioner filter device, an air filter for preventing dust from entering the inside of the air conditioner main body is provided on the front surface of the heat exchanger. It is configured to be detachable so that it can be cleaned. The filter device with such a configuration not only requires frequent maintenance, but the air filter gradually clogs until maintenance is performed, resulting in a reduction in the amount of air passing through the heat exchanger. As a result, the air conditioning capacity is reduced, leading to an increase in power consumption.

For this reason, for the purpose of reducing the maintenance work of the air filter, a filter device that scrapes off dust attached to the air filter with a brush for cleaning as in Patent Document 1 or an air filter as in Patent Document 2 A filter device has been devised that cleans the generated dust by suction.

In addition, the present invention provides a filter device for an air conditioner, wherein the partition wall is made of a resilient material.

  As a result, even if the dust accumulated inside the suction device or the exhaust duct becomes a lump of dust and gets caught between the fan and the partition wall, the partition wall is made of an elastic material. The lump of dust passes through the exhaust chamber by suction of the exhaust fan.

  The filter device for an air conditioner according to the present invention comprises a plurality of ribs on the exhaust chamber side of the elastic partition wall.

  This makes it possible to prevent the elastic partition wall from coming into contact with the fins of the exhaust fan.

The suction device includes an intake chamber, an exhaust chamber, and the intake chamber, A partition wall with a hole is provided between the intake chamber and the exhaust chamber, and the partition wall is movable.

  As a result, even if the dust accumulated inside the suction device or the exhaust duct becomes a lump of dust and gets caught between the fan and the partition, the partition is movable, Passing to the exhaust chamber side by the suction of the fan.

  The filter device of the air conditioner of the present invention can be used even if the dust accumulated in the suction device or the exhaust duct becomes a lump of dust and gets stuck between the fan and the partition wall due to long-term use. It is possible to prevent a situation in which the fan motor does not rotate.

  As a result, it is possible to exhibit sufficient performance even for long-term use, reduce the user's maintenance work, and provide "no need".

  A first invention includes an air filter, a suction nozzle, and a suction device communicated with the suction nozzle. The suction device includes an intake chamber, an exhaust chamber, and the intake chamber, and the exhaust chamber includes a plurality of suction devices. A fan provided with fins and a motor for driving the fan; and a partition covering the plurality of fins is provided between the intake chamber and the exhaust chamber, and the partition is made of an elastic material. Even if the dust accumulated inside the suction device or the exhaust duct becomes a lump of dust and gets caught between the fan and the partition wall, the partition wall is made of an elastic material. The air mass passes through the exhaust chamber side by the suction of the exhaust fan, and dust accumulated inside the suction device and the exhaust duct becomes a dust mass due to long-term use and is sandwiched between the fan and the partition wall Even if a situation arises, There can be such situation no longer rotation does not occur.

  As a result, it is possible to exhibit sufficient performance even for long-term use, reduce the user's maintenance work, and provide "no need".

  According to the second invention, a plurality of ribs are formed on the exhaust chamber side of the elastic partition wall of the first invention, and the elastic partition wall is prevented from coming into contact with the fins of the exhaust fan. It is possible to provide sufficient performance even for long-term use, reduce the user's maintenance work, and provide “no hassle”.

  According to a third aspect of the present invention, a partition having a hole between the intake chamber and the exhaust chamber is movable, and dust accumulated inside the suction device and the exhaust duct becomes a lump of dust, and the fan and the partition Even if a situation occurs between them, the partition wall is movable, so that lump of dust will pass to the exhaust chamber side by suction of the exhaust fan, and it will exhibit sufficient performance even for long-term use It is possible to reduce the maintenance work for the user and provide "no need".

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

  Here, the arrow A indicates the direction in which the sucked air flows, and the arrow B indicates the direction in which the exhausted air flows.

  FIG. 3 is an enlarged cross-sectional view showing details of a portion D in FIG. 2, and shows that the partition wall 206 has elasticity and is bent.

  About the filter apparatus of the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in FIG. 1, the dust sucked by the suction nozzle 103 passes through the suction duct 105 and is sucked by the suction device 106. Air in the suction device passes through the exhaust duct 107 and is discharged to the outside, and accordingly, dust is also discharged to the outdoors.

  Although dust accumulates in the suction nozzle 103 and the suction duct 105 due to long-term use, it may become a lump of dust and enter the suction device 106 at a certain time.

  In FIG. 2, when a lump of dust is sandwiched between the plurality of fins 203 provided on the fan 204 and the partition wall 206, the rotation of the fan 204 is prevented by frictional resistance, the motor 205 is overloaded, and the fan 204 is locked. Occurs.

  Here, as shown in FIG. 3, since the partition wall 206 is made of an elastic material, the fan 204 can be rotated even when the dust mass is sandwiched, and the dust mass is removed before the fan is locked. It can be sent to the exhaust chamber 202 side.

  That is, even when used for a long time, it is possible to reduce the maintenance of the user without causing a problem.

(Embodiment 2)
FIG. 4 shows the structure of the suction device of the filter device of the air conditioner according to Embodiment 2 of the present invention, and corresponds to FIG.
