Abstract

PURPOSE:To save cleaning such as washing of a filter and perform air- conditioning always in a good condition by winding the filter around a roller, guiding it along the rear of a front panel downward and facing the lower end of the filter to a filter taking-out port of the lower part of the front panel. CONSTITUTION:A filter 18 wound around a cylindrical roller 18 provided in the upper part of an air conditioner is placed between a front panel 17 and a heat exchanger 14 along guide plates of a filter guide 24, room air is passed through a heat exchanger 14, heated or cooled after dust of the room air sucked by the operation of an air blower 16 from the suction opening 22 of the front panel 17 is removed by the filter 19, and it is released through a diffuser 20 in the room again to perform air-conditioning in a living room. During operation a large quantity of dust is stuffed in the process in which dust adheres to the filter 19, at this time the filter 19 is pulled down from a filter taking-out hole 23, the part of a perforation 27 of the filter 19 is separated, and the filter 19 to which dust adheres is dumped. As the result cleaning of the filter 19 is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filter device for an air conditioner or the like.

BACKGROUND OF THE INVENTION Air conditioners generally incorporate a filter for air purification. That is, as shown in FIG. 3, a filter 4 is disposed at the back of a front panel 3 having a suction port 2 in a main body 1 of the air conditioner. And this filter 4
is inserted between the front panel 3 and the filter guide 5, and is fixed by locking the locking portion 6 to the front panel 3.

In addition, in the drawing, 7 is a heat exchanger, 8 is a blower, and 9 is an air outlet. In addition, the filter 4 is a structure in which a filter material 11 is welded to a frame 10 as shown in Fig. 4.The filter 4 has dust attached to it, which causes clogging and reduces the amount of air passing through, so it is necessary to periodically wash the filter with water. A cylindrical roller is installed in the upper part of the inside of the main body of the machine for the purpose of eliminating cleaning, and a belt-shaped filter having perforations in a direction perpendicular to the longitudinal direction at appropriate intervals is wound around the roller. At the same time, the filter is guided downward along the back of a front panel having a suction port, and the lower end of the filter faces the filter outlet at the bottom of the front panel.

Effect In this configuration, if the filter becomes dirty with dust, etc.
Pull out the filter by the area between the filter outlet and the suction port, cut it at the perforation, and discard it. A new filter, rolled out by a roller, will be attached to the back of the suction port.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, reference numeral 13 denotes a main body of the wall-mounted indoor unit, in which a heat exchanger 14, a drain pan 15, and a blower 16 are respectively provided, and a front panel 17 having a suction port 22 is provided on the front side. A semicircular storage section 28 is formed in an upper space 25a inside the main body 13, and a cylindrical roller 18 is rotatably accommodated in this storage section 28. A long belt-shaped filter 19 is wound around this roller 18, and a lower part 19a of the filter 19 that is fed out corresponds to the suction port 22. Further, the lower end of the filter 19 faces a filter outlet 23 formed at the lower part of the front panel 17. The filter 19
Perforations 27 are provided at appropriate intervals in a direction perpendicular to the elongated direction. An air outlet 20 is provided below the filter outlet 23, and a wind direction device 21 is provided on the air outlet 20. A filter guide 24 is provided at the filter outlet 23 .

The filter guide 24 includes fixing pieces 30, 31, 32 fixed to both sides of the main body 130, and a guide plate 33. 34 (dotted line), the lower end is provided with a long hole (not shown) so that the tip of the filter 19 can be pulled out. Further, the hole 26 of the filter guide 24 is a hole 2e that is fixed to the front panel 17, and is integrated with the front panel 17. The vertical width of the filter 19 is formed to be approximately the same as the vertical width of the filter guide 24, and the filter 19 is wound into a cylindrical shape.
It is in a suitable number of places in 9.

In the above configuration, the filter 19 wound around the cylindrical roller 18 provided at the top of the indoor unit is located between the front panel 17 and the heat exchanger 14 along the guide plate 33, 34 of the filter guide 240, Suction port 2 of front panel 17
The indoor air sucked in by the operation of the blower 16 from 2 is filtered to remove dust by the filter 19, and then transferred to the heat exchanger 1.
4, is heated or cooled, and is discharged into the room again through the air outlet 20 to air-condition the living room. During such operation, as dust adheres to the filter 19, a considerable amount of clogging occurs, and in that case, the filter outlet 2
3, the filter 19 is forcibly pulled down, the perforation 27 portion of the filter 19 is cut off, and the filter 19 with dust attached is discarded. As a result, cleaning of the filter 19 is no longer necessary.

Next, when the filter 19 wrapped around the cylindrical roller 18 is used up, the take-out panel 26 at the top of the front panel 17 is removed, and the cylindrical filter wrapped around the new filter is removed from the take-out panel 26 at the top of the front panel 17. Attach the roller 18.

In other words, the filter can be easily replaced by inserting a cylindrical roller 18 wrapped with a replacement filter 19 wrapped in a cylindrical shape.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a system in which a cylindrical roller wrapped with a filter is provided on the upper part of the indoor unit, and the filter is periodically pulled out, cut, and disposed of. Therefore, when dust accumulates on the filter and the amount of airflow decreases, you can simply pull out the filter, cut it, and dispose of it without having to clean it. In addition, unlike conventional filters, it takes time to dry them when washed with water, but since we have adopted a disposable filter that is rolled into a cylindrical shape, it is possible to cut off only the part that has dust on it. Once stored, the air conditioner can be used with a new filter at any time, and there is no reduction in air volume, which has the effect of ensuring that the air conditioner is always in good condition.
