Problems solved by technology

[0006] However, in the case of the filter device described in Patent Document 1, if cleaning is performed by scraping off with a brush, the dust will wind up on the brush, or it will be necessary to dispose of the scraped and collected dust, which does not greatly reduce maintenance. labor time
[0007] On the other hand, in the filter device described in Patent Document 2, there is also a problem that sufficient cleaning performance cannot be obtained only by the suction force.

Embodiment approach 1

[0042] figure 2 It is an overall configuration diagram of the filter device 8 of the air conditioner in Embodiment 1 of the present invention. Such as figure 2As shown, the air filter for removing dust in the air passing through the heat exchanger 4 is composed of a filter frame 10 and a filter net 12 held on the filter frame 10, and a slidable filter is installed along the surface of the air filter. Suction nozzle 14. The suction nozzle 14 can move smoothly left and right with a certain distance from the air filter by a pair of guide rails 16 provided at the upper and lower ends of the filter frame 10 . One end of a suction duct 18 is connected to the suction nozzle 14 , and the other end of the suction duct 18 is connected to a suction device 20 . The suction duct 18 is formed of a bendable duct so as not to hinder the movement of the suction nozzle 14 . Also, the exhaust duct 22 is connected to the suction device 20, and is drawn and wound outdoors. The dust adhering...

Embodiment approach 2

[0062] Figure 8 The structure of the suction device 20 provided in the filter device 8 of the air conditioner in this Embodiment 2 is shown. The overall configuration of the filter device 8 is the same as that of Embodiment 1 of the present invention, and therefore, description thereof will be omitted.

[0063] Such as Figure 8 As shown, the sirocco fan 42 is built in the suction device body 40, and the sirocco fan 42 is rotated at a high speed by a motor to exert suction. The suction duct 18 is connected to the suction side of the suction device main body 40, and the exhaust duct 22 is connected to the exhaust side. Furthermore, an opening 44 is formed on the suction side of the suction device main body 40 , and an opening and closing plate 48 connected to a stepping motor 46 is swingably attached to one side of the opening 44 . When the on-off valve 48 is driven by the stepping motor 46, the opening 44 is opened and closed. A seal 50 is attached to the opening 44 side su...

Embodiment approach 3

[0071] Embodiment 3 of the present invention is a combination of Embodiment 1 and Embodiment 2 described above, and the embodiment will be described using the dimensions of each part and the ventilation resistance value.

[0072] Figure 10 and Figure 11 The configurations of the suction nozzle 14 and the suction device 20 provided in the filter device 8 of the air conditioner according to Embodiment 3 of the present invention are respectively shown. The overall configuration of the filter device 8 is the same as that of Embodiment 1 of the present invention, and thus description thereof will be omitted.

[0073] Such as Figure 10 Shown, the basic structure of suction nozzle 14, with reference to Figure 7 The suction nozzle described in Embodiment 1 is the same, however, as a specific size, the size of the suction hole 30 is set to be 4 mm wide x 16 mm long, so that the opening area is set to 64 mm. 2 . In addition, as the auxiliary opening 34 of the suction nozzle 14,...

Abstract

The present invention provides an air conditioner, comprising an indoor unit having a heat exchanger and a fan for blowing an air heat-exchanged by the heat exchanger into a room which are stored in the body of the indoor unit. The air conditioner also comprises an air filter fitted to the body on the upstream side of the heat exchanger, a slidably movable suction nozzle having a first suction hole facing the air filter and sucking dust adhered to the air filter, and a sucking device communicating with the suction nozzle. Also, at least one second suction hole is formed in the suction nozzle near the first suction hole so that the flow rate of the air sucked by the suction nozzle can be changed.

Description

technical field [0001] The present invention relates to an air conditioner provided with a function of automatically cleaning an air filter provided at an air suction port of an indoor unit. Background technique [0002] In a conventional air conditioner indoor unit, an air filter for preventing dust from entering the air conditioner body is provided in front of the heat exchanger, and the air filter is detachably constructed so that dust can be cleaned by hand. The filter unit with such a configuration not only requires frequent maintenance, but also the mesh of the air filter is gradually clogged until the maintenance is carried out. Big. [0003] Therefore, for the purpose of reducing the labor time of maintenance of the air filter, a filter device that scrapes off the dust adhering to the air filter with a brush and cleans it, or a device that sucks the dust adhering to the filter and cleans it has been proposed. Filter device (for example, refer to Patent Document 1 o...
