Background technology
In ceiling suspension type air conditioner in the past, the housing of thermal converter, indoor blower in the receiving room is suspended on the ceiling by hanging piece and the lifting bolt that is installed on the ceiling, on lifting bolt, assembling up and down two pieces of packing rings and nut, clamp hanging piece with two pieces of packing rings about this, screw togather fixingly with nut, housing is suspended on the ceiling.
But, in fixed structure in the past, because the upside packing ring may fall under the gravity effect when installing, so will the upside packing ring be fixed on the upside nut with adhesive tape (tape) etc., perhaps in order to prevent that the upside packing ring from coming off, except the packing ring of upside, will be temporarily fixed at (for example, with reference to patent documentation 1) on the lifting bolt by the packing ring retention tab that cardboard is made in addition.
, if utilize the packing ring retention tab of record in the patent documentation 1,, therefore can increase cost because this packing ring retention tab is the other part that is different from packing ring.And, have the assembling back, use the packing ring retention tab that is removed when finishing to remain in problem on the ceiling with the form of rubbish easily.In addition, exist the installing hole be arranged on the hanging piece to be not easy to the problem of lifting bolt by, operability difference.

The specific embodiment
With reference to accompanying drawing the ceiling suspension type air conditioner that one embodiment of the invention relates to is described.
Fig. 1 is the stereogram of the ceiling suspension type air conditioner that relates to of one embodiment of the invention.
As shown in Figure 1, the ceiling suspension type air conditioner 1 that one embodiment of the invention relates to has housing 2, and this housing 2 is being taken in all not shown indoor heat converter and indoor blower.Decoration panel p is installed below housing 2, and this decoration panel p has the grid of suction 2p
1And blow-off outlet 2p
2
Housing 2 is suspended on by four groups of the same installing mechanisms 3 and is installed on the ceiling 4.
As shown in Figures 2 and 3, each installing mechanism 3 possess the lifting bolt 5 that is installed on the ceiling 4, the hanging piece 6 on the sidewall 2a that is installed in housing 2, from clamping this hanging piece 6 up and down and allowing upside packing ring 7 and downside packing ring 8 that lifting bolt 5 connects and be screwed on upside nut 9 and downside nut 10 on the lifting bolt 5.
As shown in Figures 3 and 4, hanging piece 6 is a sheet metal system, observation from the side slightly is コ word shape, and possesses the planar portions 6a that is provided with screwed hole 6a1, upright decoration panel installation portion 6b and the upright bolt installation portion 6c that is located at the planar portions 6a other end that is located at the end of this planar portions 6a and is provided with screwed hole 6b1.On this bolt installation portion 6c, the installing hole 6c1 that is provided with L word shape roughly and lifting bolt 5 is connected; On this installing hole 6c1, be provided with to be communicated with this installing hole 6c1 and bolt that lifting bolt 5 passes through is inserted and use hole 6c2, and with the end, inserting side of hole 6c2 guiding (guide) is being set in this bolt insertion and uses notch part 6c3.
Hanging piece 6 is installed on the sidewall 2a, and by making planar portions 6a butt one sidewall 2a inboard, being screwed togather to be fixed on the sidewall 2a by screwed hole 6a1 and carry out, bolt installation portion 6c is exposed to outside the housing 2 from the opening 2a1 that a sidewall 2a is provided with.
As shown in Figure 5, upside packing ring 7 is for sheet metal system and be circular plate shape, is provided with the bolt through hole 7a that lifting bolt 5 connects (loose fit) in the position of departing from its center of gravity.
Below, describe using installing mechanism 3 that housing 2 is hanging on the ceiling 4.
As Fig. 3 and shown in Figure 6, hanging piece 6 is installed on housing 2 when dispatching from the factory in advance, the bolt installation portion 6c of hanging piece 6 is exposed at the outside of housing 2.
On the lifting bolt 5 that is installed on ceiling 4, screw togather upside nut 9, and be located at suitable height.
In addition, make upside packing ring 7 connect lifting bolt 5, and separate, be positioned at suitable height with upside nut 9.At this moment, as shown in Figure 5, owing to be provided with bolt through hole 7a in the position of departing from center of gravity on the upside packing ring 7, therefore, upside packing ring 7 tilts naturally, and temporarily remains on desired position by the cooperation of lifting bolt 5 and bolt through hole 7a, can not come off.Be that upside packing ring 7 has the function that keeps institute phase position.
In addition, make downside packing ring 8 connect hanger bolt 5, screw togather downside nut 10, make downside packing ring 8 be positioned at the position of specified altitude.Four groups of installing mechanisms 3 are carried out same operation.
Subsequently, lift housing 2, insert by bolt and use hole 6c2, make lifting bolt 5 connect the installing hole 6c1 of hanging piece 6, utilize four groups of installing mechanisms, 3 support housings 2, and suitably rotate downside nut 10 as required, carry out horizontal aligument.
After horizontal aligument finished, releasing lifting bolt 5 cooperated with bolt through hole 7a's, and upside packing ring 7 is descended, and the planar portions 6a of butt hanging piece 6, clamped planar portions 6a by upside packing ring 7 and downside packing ring 8; Then, rotate upside nut 9 and make its decline, be situated between, strengthen the fixed pan 6a of portion, housing 2 is suspended on the ceiling 4 by upside nut 9 and downside nut 10 by upside packing ring 7 and downside packing ring 8.
Above-mentioned when being suspended on housing on the ceiling, has the function that keeps institute phase position by upside packing ring 7, thereby can temporarily keep desired position, so in the assembly manipulation of housing, when lifting bolt 5 passes through the installing hole 6c1 of hanging piece 6, upside packing ring 7 can not come off, and assembly manipulation is simplified.
In addition, guiding is set uses notch part 6c3, make the operation of lifting bolt 5 perforation installing hole 6c1 become easy by insert end, inserting side with hole 6c2 at bolt.
In addition, have the function that keeps institute phase position by upside packing ring 7, do not need to use upside packing ring 7 packing ring retention tab in addition, both cheapness can not produce rubbish yet.
According to the ceiling suspension type air conditioner of present embodiment, do not produce rubbish, ceiling suspension type air conditioner that assembly manipulation is good in the time of realizing cheap and assembling.
In addition, the variation to the upside packing ring describes.
The upside packing ring that relative the foregoing description uses is circular plate shape, and this variation is used elliptical shape.
For example, Fig. 7~shown in Figure 9, installing mechanism 3 possess the upside packing ring 7A and the downside packing ring 8 of bolt 5, hanging piece 6A, this variation and are screwed on upside nut 9 and downside nut 10 on the lifting bolt 5.
Upside packing ring 7A is an ellipticity, is provided with the bolt through hole 7a that lifting bolt 5 connects (loose fit) in the position of departing from center of gravity.
Therefore, upside packing ring 7A has the function that keeps institute phase position, and in the assembly manipulation of housing, when lifting bolt passed through the installing hole of hanging piece, the upside packing ring can not come off, and assembly manipulation is easy.
As shown in figure 10, preferred upside packing ring 7A makes by the planar portions 6Aa stamping-out from hanging piece 6A.Therefore, do not spend fee of material and just can make the upside packing ring, and can make the hanging piece lightweight.
Other structures and upside packing ring shown in Figure 4 do not have difference, have therefore omitted the explanation to prosign.
