Afterwards, instrument is aimed at the operation screw 44 that expose in the bight of suction inlet 17, and will operate screw 44 to fastening direction rotary manipulation.
So by the advance and retreat of screw pressing piece 48 restriction operation screws 44, on the other hand, the tilting member 36 with the screwed hole 40 that screws togather with operation screw 44 is by the swing application of force.Tilting member 36 tilts, and near below the screw operating portion 35, colludes the bottom surface of lacing film 42 near tilting member resettlement section 31 so that screwed hole 40 side ends of tilting member 36 lift.
When hook pawl 41 is engaged to connecting hole 51 with collude lacing film 42 and descend integratedly, the bight of hooking sheet 50 and edged surface plate 21 is drawn in the direction of peristome 20 to height adjustment.And when the fastening operation proceeded operation screw 44, hook pawl 41 gets in the connecting hole 51 more deeply, and edged surface plate 21 by card reliably only.
Then, like Fig. 6～shown in Figure 8, edged surface plate 21 embeds height adjustment fully with peristome 20, and second jut 56 of edged surface plate 21 engages with the hole portion of height adjustment with peristome 20 perisporiums.Edged surface plate 21 is fixed on the identical face with panel body 3A reliably, can not edged surface plate 21 be taken off from panel body 3A face.
As required when panel body 3A takes off edged surface plate 21, carry out with being described below.
At first, as shown in Figure 6, open suction inlet 17, the screw operating portion 35 of edged surface plate mounting mechanism K is exposed in its bight.At this moment, instrument alignment function screw 44 also will be operated screw 44 to lax direction rotary manipulation.Tilting member 36 swings, being left behind in the end of operation screwed hole 40 sides, colludes the end of lacing film 42 sides and risen with peristome 20 laybacks to height adjustment.
Thereupon, hook pawl 41 makes hooking sheet 50 rise and moves via connecting hole 51, and lift to the direction of leaving from panel body 3A face in second bight of edged surface plate 21.Edged surface plate 21 tilts and a part is outstanding from panel body 3A, second jut 56 from the hole portion deviate from.The state that first jut, 55 maintenances in first bight engage with hole portion.
When the rotary manipulation proceeded operation screw 44, like Fig. 9～shown in Figure 11, tilting member 36 tilts the biglyyest, and hook pawl 41 shoals with respect to the engaging of connecting hole 51.Even in this state, first jut 55 also engages with hole portion, and the part of edged surface plate 21 is deviate from peristome 20 and become lateral attitude from height adjustment.
That is, edged surface plate 21 only ends the power support with small card with respect to panel body 3A.If to the pulling of the direction left from main body 3A, then connecting hole 51 is deviate from from hook pawl 41 with edged surface plate 21, simultaneously first jut 55 from the hole portion deviate from, and can take off edged surface plate 21 from panel body 3A.
The more than operation of explanation is actually and under the state of the decoration panel 3 that exposes from ceiling floor that looks up, carries out, and therefore, the operation of operation screw 44 is also carried out with looking up.At this moment, operation screw 44 is pushed by screw pressing piece 48, therefore can in the operation way, not come off, and operation property is good.Certainly, tilting member 36 and other component parts can not come off yet.
Through adopting above-mentioned edged surface plate mounting mechanism K, do not need to make as in the past the edged surface plate just to move and can install and remove along diagonal, therefore, improve operation property, and help increasing the selection in the design.
And, carrying out under the fixing situation of screw thread the tongue piece portion that can not extend as in the past owing to the problem of intensity on the edged surface plate tongue piece portion being set.Therefore, the height adjustment of panel body with the bridging part between peristome and the suction inlet can not set broad, like this, except designing, also be unfavorable for the intensity of panel body.
Relative therewith, if adopt above-mentioned edged surface plate mounting mechanism K, then can with the height adjustment of panel body 3A with the bridging part between peristome 20 and the suction inlet 17 set broad, help increasing the intensity of panel body 3A.
Below, the suction grid 18 on the suction inlet 17 that is installed in decoration panel 3 is described with the related formation of panel body 3A.
Figure 12 is for having carried out the stereogram in cross section from the suction grid 18 of decoration panel 3 to blow-off outlet 19, Figure 13 is its partial enlarged drawing, representes accordingly with the state of holding that hangs of the indoor unit 1 of reality.
In the panel body 3A of suction inlet 17 face side, be provided with from the crooked laterally stage portion 60 of side face along periphery.Sucking grid 18 does, along the outstanding integratedly laterally extension 18a that is formed with of face side periphery.Under the state that will suck grid 18 embedding suction inlets 17, the extension 18a that sucks grid 18 inserts the stage portion 60 of panel body 3A.
Thus, under the state of suction grid 18 that looks up, extension 18a covers suction inlet 17 and sucks the gap between the grid 18.Can only feel the jump of stage portion 60 sucking grid 18 and the seam of panel body 3A, sucking grid 18 becomes in appearance impression as thin as a wafer, and has improved attractive in appearance.
In fact, the gap turn narrow between suction inlet 17 and the suction grid 18 is difficult to from this gap suction air.That is, do not reduce, can improve the dust capturing efficiency of filter through being installed in the air capacity that sucks the filter on the grid 18.
In addition, the invention is not restricted to above-mentioned form of implementation itself, the implementation phase in not breaking away from the scope of inventing spirit, can change and specific inscape.And,, can form various inventions through appropriate combination to the disclosed a plurality of inscapes of above-mentioned form of implementation.
