Yes.

  The filter support frame 62 is integrally formed of a resin material, and has elasticity enough to be bent into a substantially L shape when the suction filter 33 is inserted. Further, the vertical girder portion 64 and the horizontal girder portion 65 enhance the rigidity of the filter support frame 62 as long as the bending of the filter support frame 62 is not hindered.

  In addition, as shown in FIGS. 8 and 10, the upper frame portion 63 a of the frame portion 63 is provided with a guide portion 67 having a triangular section (see FIG. 10) formed in a tapered shape upward. As shown in FIG. 10, a guide guide portion 68 inclined upward is formed on the front surface of the guide portion 67. As shown in FIG. 10, the height H <b> 1 of the guide portion 67 with the upper frame portion 63 a as a base point is formed higher than the height H <b> 2 of the disposable filter material 61 in a state where it is attached to the filter support frame 62.

When the suction filter 33 enters the gap δ, the guide portion 67 is a member that abuts on the filter guide portion 43A (FIG. 3) and guides the suction filter 33 to the gap δ. Specifically, in the process in which the suction filter 33 enters the gap δ, the guide guide portion 68 formed in the guide portion 67 contacts the filter guide portion 43A (FIG. 3) described above, and the filter guide portion 43A The suction filter 33 is smoothly guided to the gap δ according to the inclination. While the suction filter 33 enters the gap δ backward, the guide guide portion 68 slides backward while contacting the curved rib 45 described above, and the suction filter 33 is moved to a predetermined position. The suction filter 33 is guided until it is disposed at the position.
Here, since the height H1 of the guide part 67 is formed higher than the height H2 of the disposable filter material 61, the guide part 67 becomes a barrier in the process of the suction filter 33 entering the gap δ, and the disposable filter The material 61 does not come into contact with the filter guide portion 43A, the curved rib 45, and the like, so that the disposable filter material 61 is prevented from being turned over or peeled off from the base filter 60.

  Further, the left frame portion 63c of the frame portion 63 of the filter support frame 62 has a wide portion 63L (not shown in FIG. 8) whose width is lower as shown in FIG. 7, FIG. 8, and FIG. In the same manner, the right frame portion 63d is formed with a wide portion 63R that is wide at the bottom. These wide portions 63L and 63R are members that are inserted under the above-described pressing piece 38E of the lifting frame 38 and supported by the pressing piece 38E. In this embodiment, the pressing piece 38E is formed such that the lower end portion of the pressing piece 38E has a larger gap with the frame body 38A than the upper end portion. For this reason, when the disposable filter 33 is attached to the fourth elevating frame 38, the upper end portion of the disposable filter 33 can be easily inserted under the pressing piece 38E, and the attachment work can be simplified. ing. Further, since the pressing piece 38E presses the substantially middle portion of the suction filter 33, the suction filter 33 is prevented from falling to the side away from the lifting frames 35 to 38, and when the lifting frames 35 to 38 are all retracted, The filter 33 is stored so as to cover the suction ports 15 and 17 smoothly.

As shown in FIGS. 7 and 8, two connecting holes 69 for connecting the suction filter 33 to the lifting frame 38 are formed in the lower frame portion 63 b of the frame portion 63 of the filter support frame 62. The connection hole 69 is a hole that engages with the above-described connection piece 38 </ b> F of the elevating frame 38. The inner diameter of the connecting hole 69 is formed to be approximately the same as the outer diameter of the connecting piece 38F, and the connecting piece 38F can be fitted into the connecting hole 69 with a small force.
In this configuration, the filter 33 is inserted below the pressing piece 38E provided on the lifting frame 38, and the suction filter 33 is provided on the connecting piece 38F provided on the lower end of the fourth lifting frame 38. The suction filter 33 can be held by the lifting frames 35 to 38 by a simple operation such as fitting the connecting hole 69.

  Also, as shown in FIGS. 8 and 9, a disposable filter material 61 is detachably attached to the base filter 60 so as to cover the front surface thereof, that is, the entire surface on the side facing the suction ports 15 and 17. It is done. The disposable filter material 61 is a member for collecting dust contained in the passing air. The disposable filter material 61 is interposed between the suction ports 15 and 17 and the base filter 60 and is sucked from the suction ports 15 and 17. Is configured to collect most of the dust contained therein before reaching the base filter 60. Further, the disposable filter material 61 is configured to collect oil contained in the air sucked from the suction ports 15 and 17 and prevent the base filter 60 from being contaminated due to the oil. For this reason, in the state where the disposable filter material 61 is attached to the base filter 60, the base filter 60 is prevented from being contaminated by dust or oil as much as possible, and the frequency of cleaning the base filter 60 can be reduced. The labor required is reduced.

In addition, a plurality of disposable filter materials 61 are prepared in advance, and when the disposable filter material 61 is attached to the base filter 60 for a predetermined period and becomes dirty with dust or the like, this old disposable filter material 61 is attached. 61 is removed from the base filter 60 and discarded, and a new disposable filter material 61 that is not used can be attached to the base filter 60.
For this reason, when a user, a user, or the like cleans the suction filter 33 after operating the air conditioner 1 for a certain period, the dirty disposable filter material 61 after use is discarded, and the disposable filter material 61 before use is discarded. The suction filter 33 can be cleaned by a simple and simple operation of attaching the filter to the base filter 60, thereby simplifying and speeding up the operation. Further, for example, when the disposable filter material 61 is used in a kitchen or the like, even if oil adheres to the filter material 61, it can be disposable without cleaning the filter material 61. improves.

Here, the net part 66 and the disposable filter material 61 of the suction filter 33 will be described in detail.

It is a graph which shows the relationship between the surface wind speed in the state which accumulated the part 66 and the disposable filter raw material 61, and the pressure loss.
In the present embodiment, as shown in FIG. 15, the total pressure loss of the pressure loss of the mesh portion 66 of the base filter 60 and the pressure loss of the disposable filter material 61 is allowed to exhibit the function of the suction filter 33. It is specified to be within the range of pressure loss. Specifically, in a state in which the net portion 66 and the disposable filter material 61 are overlapped, as shown in FIG. 15, the pressure loss generated when the surface wind speed is 1 m / sec is within the range with 3 Pa as the upper limit. It is prescribed as follows.
In order to realize this, as shown in FIG. 13, the net 66 is configured such that the pressure loss generated when the surface wind speed is 1 m / sec is a value with an upper limit of 1 Pa, and the disposable filter material. As shown in FIG. 14, 61 is configured such that the pressure loss generated when the surface wind speed is 1 m / sec has a value with 2 Pa as the upper limit. As a result, even when the mesh portion 66 and the disposable filter material 61 are overlapped, the pressure loss due to the mesh portion 66 and the disposable filter material 61 is suppressed to a pressure loss for exhibiting the function of the suction filter 33 as a filter. It is possible to efficiently collect dust and the like.

  The pressure loss of each of the net portion 66 and the disposable filter material 61 can be arbitrarily designed on the condition that the total pressure loss is within the allowable pressure loss range described above. Therefore, for example, when the disposable filter material 61, which tends to be expensive because it is disposable, is designed to be thin for cost reduction (that is, when the pressure loss is lowered), it is within the allowable pressure loss range. Thus, the pressure loss of the net 66 can be designed to an appropriate value so that the dust collection function of the suction filter 33 can be maintained.

In FIG. 16, the horizontal axis indicates the passage of time from the start of the operation of the air conditioner 1, and the vertical axis indicates when the dust remaining in the conditioned room at the start of the operation of the air conditioner 1 is 100%. , Shows the concentration of cotton dust.
