Problems solved by technology

[0009] However, in conventional air cleaners with detachable air filters, regular maintenance is required to remove the air filter from the air conditioner according to the frequency of use of the air conditioner, and to wash it with water or use a cleaning machine to remove the attached dust. , very troublesome
In addition, if periodic maintenance is not performed, the air resistance of the intake air increases due to the accumulation of dust on the air filter, so there is a problem that the performance of the air conditioner decreases or the power consumption increases.
[0010] In addition, in the air conditioner disclosed in Patent Document 1, each time the air filter is cleaned, the electric cleaner is taken out, and the suction nozzle is connected to the suction port of the brush cover, which must be moved along the air filter, which is very time-consuming. and time-consuming issues
[0011] In addition, in the case of using the filter device described in Patent Document 2, the dust adhering to the air filter is automatically sucked, but since the sucked dust is collected in the separator, it is necessary to periodically remove the dust accumulated in the separator. The dust in the air filter is very troublesome, and if the removal is delayed, the dust attached to the air filter will not be removed, the ventilation resistance of the inhaled air will increase, the performance of the air conditioner will decrease, or the power consumption will increase.
[0012] In addition, in the case of adopting the filter device described in Patent Document 3, a long brush having approximately the same length as the overall width of the air filter is required, and since the air filter is formed in a belt shape, the thickness increases, The problem of increasing the intrinsic size of the body

Embodiment approach 1

[0042] Figure 1 ~ Figure 3 shows the indoor unit of the air conditioner according to Embodiment 1 of the present invention, figure 1 is the front view of the indoor unit, figure 2 and image 3 are along figure 1 Sectional view of line I-I and line II-II.

[0043] Such as Figure 1 ~ Figure 3 As shown, in the interior of the indoor unit main body 11, the heat exchanger 10 is accommodated, and the fan 14 for sucking indoor air through the heat exchanger 10 and blowing the air heat-exchanged by the heat exchanger 10 into the room is arranged on the heat exchanger. The filter device 1 on the upstream side of 10 sucks in air from a plurality of suction ports (not shown) formed across the front of the main body 11 by operating the fan 14, and passes through the suction port and the heat exchanger 10. The filter device 1 in between removes the dust floating in the air.

[0044] Such as Figure 4 As shown, the filter device 1 is provided with: a filter frame 2; an air filte...

Embodiment approach 2

[0052] Figure 6A and Figure 6B It shows the suction nozzle 4 provided on the indoor unit of the air conditioner according to Embodiment 2 of the present invention, and a partition wall 4c extending longitudinally is provided between the suction port 4a of the suction nozzle 4 and the connection portion of the suction pipe 3, and the partition wall 4c is provided with a through-hole 4d whose opening width is small near the connection portion of the suction pipe 3 and gradually increases as the distance from the connection portion increases.

[0053] Since other configurations are the same as those in Embodiment 1, description thereof will be omitted.

[0054] In this embodiment, when air is sucked from the suction nozzle 4, since the through-hole 4d whose opening width gradually increases upward is formed on the partition wall 4c inside the suction nozzle 4, the wind speed at the suction port 4a is independent of the distance from the suction pipe. No matter the distance of...

Embodiment approach 3

[0062] Figure 8 Shown is a filter device 1 provided on an indoor unit of an air conditioner according to Embodiment 3 of the present invention, which replaces the suction pipe 3 provided on the filter device 1 of Embodiment 1 or 2, The suction nozzle 4 is connected to the suction exhaust device 6 through the flexible suction pipe 15 .

[0063] The suction pipe 15 is connected at one end to the suction and exhaust device 6, and its other end, viewed from the suction and exhaust device 6, is connected to the opposite side of the lower end of the suction nozzle 4, and its middle part is bent into Roughly U-shaped. In addition, the suction nozzle 4 can smoothly move left and right while maintaining a narrow gap with the air filter 5 through the guide rails 16 provided on the upper and lower ends of the filter frame 2 .

[0064] In the filter device 1 of the above-mentioned structure, if the suction and exhaust device 6 starts to operate, the suction nozzle 4 positioned at one e...

Abstract

Inside an indoor body of an air conditioner are received a heat exchanger and a fan for blowing air that has been subjected to heat exchange in a heat exchanger. An air filter is installed in the body on the upstream side of the heat exchanger. A suction nozzle having a suction opening opposite the air filter and sucking dust adhered to the air filter is slidably installed in the body, a suction / discharge device communicating with the suction nozzle and sucking / discharging the dust with air is provided in the body, and ventilation paths are provided in the suction nozzle.

Description

technical field [0001] The present invention relates to an air conditioner provided with a function of automatically cleaning an air filter provided on an air suction port of an indoor unit. Background technique [0002] Conventional air conditioners such as Figure 15 and Figure 16 As shown, the air filter 5 for preventing the intrusion of dust into the main body 11 is provided on the front of the heat exchanger 10, and the dust adhering to the air filter 5 can be removed manually, and it is detachably configured. [0003] In addition, as an air conditioner that is easy to clean the air filter, it has a rotating brush, a brush cover that rotatably supports the rotating brush while covering it, and a pinion filter brush coaxially provided with the rotating brush. The suction nozzle is connected to the suction port provided on the brush cover, moves along the air filter, and scrapes and sucks the dust accumulated on the air filter with the rotating brush to form an air cond...
