Description

air conditioner

technical field

The present invention relates to an air conditioner, in particular to an air conditioner with an automatic cleaning function of an air filter. the

Background technique

In an air conditioner, indoor air drawn in by a blower fan is passed through a heat exchanger, thereby cooling or heating it and returning it to the room, but in order to prevent the dust floating in the room from contaminating the heat exchanger, the An air filter is provided on the front side of the exchanger. When dust adheres to the filter to clog the filter and increase ventilation resistance, the air conditioning capability of the air conditioner decreases and power consumption increases. In order to eliminate such disadvantages, various air conditioners having an automatic filter cleaning function have been proposed. the

In order to automatically clean the filter, there is a method disclosed in Japanese Patent Application Laid-Open No. 62-145019 (JP62-145019U). In this method, a belt filter formed in an endless shape is supported by a pair of rollers, and the belt filter is moved by rotating the rollers with a motor, and in this process, the filter is cleaned by a rotating cleaning brush. . In addition, as a method of moving the filter, as shown in Japanese Patent Laid-Open No. 2001-99479 (JP2001-99479A), there is also a method of winding a belt-shaped filter wound on one roll on another roll. , a method of cleaning with a cleaning brush in this process. In this case, the filter is rewound from the other roll onto the one roll after cleaning. the

In the case of JP62-145019U, the dust removed from the filter is accumulated in a dust box (dust box) (dust accumulator) arranged in front of or below the cleaning brush, and when it is full, or periodically using the vacuum cleaner Suction, etc. for cleaning. Furthermore, in JP62-145019U, the dust collecting box is detachably attached to the air conditioner main body, and can be detached from the air conditioner main body for cleaning or washing. However, since the cleaning brush is connected to the drive motor, it cannot be detached from the air conditioner main body. the

In the air conditioner of JP62-145019U, there is a problem that accumulated dust tends to scatter when the dust box is detached from the main body. the

And it is an air conditioner that can be handled easily. the

In order to prevent the dust removed from the filter from scattering around, in the air conditioner of JP62-145019U, for example, it is conceivable to provide an openable and closable cover covering the opening of the dust box. However, it is difficult to arrange such a cover body while avoiding interference with the cleaning brush, and it is difficult to perform an opening and closing operation. the

On the other hand, it is also considered that the cleaning brush is rotatably installed on the dust box, and that the cleaning brush and the dust box can be attached and detached together. In this case, the cleaning brush replaces the cover, and the dust in the dust box is difficult to scatter. However, the cleaning brush becomes an obstacle when discarding the dust in the dust box or when vacuuming with a vacuum cleaner. Even if the cleaning brush is arranged on the dust box in a detachable manner, the structure is complicated and the detachment operation is troublesome. the

Therefore, in the air conditioner according to the present invention, in an air conditioner having a cleaning brush for removing dust adhering to the filter, and a dust box for storing the removed dust, it is characterized in that the dust box is detachably mounted. On the main unit of the air conditioner, and the dust collecting box is composed of a box main body and a cover body which is freely opened and closed on the box main body, and an opening is formed on the cover body; inside the dust collecting box, the above-mentioned cleaning brush It is rotatably provided on the cover body, and the bristles protrude outward from the opening. the

According to the above configuration, the dust box can be detached from the air conditioner main body in a state where the cover body is covered on the box main body. Therefore, the dust stored in the dust box will not be scattered. Furthermore, the dust collecting box detached from the air conditioner main body can be easily disposed of by opening the cover and sucking the dust in the box main body with a vacuum cleaner. At this time, since the cleaning brush is attached to the lid side, cleaning of the cartridge main body is easy. the

In one embodiment, the above-mentioned cover body is rotatably connected to the box main body by a hinge. Therefore, the opening and closing operation of the lid is easy, and the lid will not be lost. the

In one embodiment, the bearing is slidably assembled on the cover and fixed by claws provided on the cover, the bearing supports the cleaning brush and allows the cleaning brush to rotate freely. The structure is simple, and the installation work of the cleaning brush is easy. the
