In addition, it is configured to be movable between a normal arrangement position and a take-out position moved to the opening position of the air suction port 6 in conjunction with a turning operation for lifting the front end side of the suction grill 7 upward.

With the configuration described above, according to the present embodiment, the following operational effects can be obtained.
By the operation of the air conditioner 1, room air is sucked into the unit body 2 from the air suction port 6 on the upper surface of the unit body 2 through the suction grille 7, and dust contained in the air is captured by the prefilter 9. Collected and removed. Part of the air that has passed through the pre-filter 9 is further purified by passing through the air purifying filter 14, and then cooled or heated in the process of passing through the indoor heat exchanger 4 together with other air to adjust the temperature. . The temperature-controlled air is blown into the room from the outlet 11 via the indoor fan 5 and used for indoor cooling or heating.

  The dust collected by the pre-filter 9 accumulates on the filter surface as the operation time of the air conditioner 1 elapses, and becomes a ventilation resistance to reduce the operation efficiency of the air conditioner 1. It is necessary to remove it by cleaning. At this time, as shown in FIG. 2, the front end side of the suction grill 7 is lifted upward, and the prefilter 9 is pulled out and cleaned, so that the accumulated dust can be removed. By resetting, the pre-filter 9 can be restored to a state where no dust is attached.

  Similarly, the air purifying filter 14 disposed in the air flow path 12 on the downstream side of the prefilter 9 also deteriorates its function when used for a certain period of time, so that maintenance and replacement are necessary. During maintenance and replacement of the air cleaning filter 14, the front end of the suction grill 7 is lifted upward and rotated to take out the entire storage case 14 </ b> A from the holder 15. However, the suction grill 7 is lifted upward and rotated. Then, since the holder 15 that accommodates and holds the air purification filter 14 is connected to the suction grille 7 via the link 17, the air purification filter 14 is moved together with the holder 15 to the air as shown in FIGS. 2 and 4. It can be taken out to the opening position of the suction port 6.

Therefore, when the front end side of the suction grille 7 is lifted upward and rotated, it is linked to the front end side of the suction grille 7 via a link 17 in conjunction with the operation. The front end side of the holder 15 is lifted upward with the rear end side being pivotally supported as a fulcrum. Thereby, the air purifying filter 14 arranged in the air flow path 12 in the unit main body 2 can be moved together with the holder 15 to the opening position of the air suction port 6.

For this reason, even if the height of the unit main body 2 is increased or the unit main body 2 is installed at a high position such as a wall surface, it is connected to the suction grille 7 in the air flow path 12 in the unit main body 2. The air purifying filter 14 thus arranged is taken out from the holder 15 at that position by taking it out to the opening position of the air suction port 6 in conjunction with the pivoting operation of lifting the front end side of the suction grill 7 upward. The storage case 14A can be removed by holding the handle 14B, and necessary maintenance and replacement work can be performed.
Therefore, it is possible to facilitate maintenance and replacement work for the air cleaning filter 14 disposed in the air flow path 12 in the unit main body 2.

Further, the air purifying filter 14 is disposed in the air flow path 12 at the upper front surface of the front side heat exchanger 4 </ b> A that is inclined in the unit main body 2 from the front surface side to the upper rear side. For this reason, the air purification filter 14 does not obstruct the air flow sucked from the air suction port 6 provided on the upper surface of the unit main body 2, and the air purification filter 14 becomes a pressure loss factor at the air suction port 6. It is possible to suppress a decrease in the amount of indoor air sucked by the.
Accordingly, it is possible to suppress a decrease in the air volume caused by the air cleaning filter 14 and to maintain high performance of the air conditioner 1.

Furthermore, in this embodiment, the air purifying filter 14 is installed via the holder 15, and is detachable from the holder 15 in a state where the air purifying filter 14 is taken out to the opening of the air suction port 6. Therefore, when inspecting or replacing the air purification filter 14 as a generic name of a deodorizing filter, various sterilization filters, allergen deactivation filters, HEPA filters, etc., the unit main body 2 side and the suction grille 7 in the unit main body 2 Can be easily inspected or replaced.
Therefore, serviceability with respect to the air purification filter 14 can be maintained and secured.

  In addition, this invention is not limited to the invention concerning the said embodiment, In the range which does not deviate from the summary, it can change suitably. For example, in the above-described embodiment, an example in which the present invention is applied to an integrated air conditioner has been described. However, the present invention is not limited to this, and the same applies to a separated air conditioner in which an indoor unit and an outdoor unit are separated. Of course, it can be applied. In the above-described embodiment, the example in which the pre-filter 9 and the air purifying filter 14 are divided into right and left parts and arranged as a pair has been described. Needless to say, the arrangement is not limited to two.

  Furthermore, in the above embodiment, the air purifying filter 14 is supported by pivotally supporting one end side of the holder 15 that houses and holds the air purifying filter 14 and connecting the other end side to the suction grille 7 via the link 17. Although the example which made it possible to take out 14 to the opening part position of the air suction inlet 6 was demonstrated, the air purifying filter 14 is taken out to the opening part position of the air suction inlet 6 with another connection structure, such as replacing the link 17 with a wire. It is good also as a structure which can do.
