That is, the 10a of suction portion of drainage pump 10 is being supported with being completely infused in the drainage water that collects in the drain pan 7.Support the pump supporter 17 of drainage pump 10 have from the 17a of pump support sector to directly over the shank 17b that extends of position, the upper end of this shank 17b is fixed on the top board 1a that constitutes indoor set main body 1.
A side is provided with the discharge portion of discharge from the drainage water of the 10a of suction portion suction in the inside of drainage pump 10, and an end of discharge hose 19 is connected here.Discharge hose 19 is wound between the shank 17b of pump supporter 17 from discharge portion, recrosses between upper end and the indoor set top body plate 1a of above-mentioned heat exchanger 6 and places a circle.
That is, depression is formed with the part of the heat insulating member 4 that is installed in housing 3 the insides on the top board 1a of indoor set main body 1, and discharge hose 19 is punctured among this depressed part b.Though be necessary above-mentioned heat insulating member 4 is processed,, therefore influence operation hardly owing to only form depressed part b.And, to the upper end of heat exchanger 6 without any need for processing, to operation not influence fully.
The lower surface of above-mentioned heat exchanger 6 is loaded on the lug boss d on the underside wall that is arranged on drain pan 7 integratedly.On the other hand, the upper surface of heat exchanger 6 contacts with the heat insulating member 4 that the top board 1a of indoor set main body 1 goes up setting.That is, heat exchanger 6 is clamped between indoor set top body plate 1a and the drain pan 7 from above-below direction.
But if in drain pan 7 upper edges the lug boss d that supports heat exchanger 6 is set the full week of underside wall of whole drain pan 7, then the drainage water of heat exchanger 6 generations is divided into the inboard and the outside of lug boss d.Relative therewith, above-mentioned discharge opening 8 and drainage pump 10 are arranged on the inside line of heat exchanger 6.
Therefore, at least one place of lug boss d, cut processing lug boss d with to a certain degree length dimension.That is, lug boss d is interrupted, the underside wall of drain pan 7 is exposed at this discontinuities e.Thus, the drainage water that runs down into the outside left of lug boss d from heat exchanger 6 is imported into inside line through discontinuities e, discharges from discharge opening 8 or drainage pump 10.
Be described in detail discharge opening 8 below and cover 18 with sluicing.
Fig. 4 covers 18 stereogram for pulling down from discharge opening 8 to sluice.
Above-mentioned discharge opening 8 has the lug boss that is arranged on the below along side face integratedly, and the internal perisporium of this lug boss is provided with the internal thread part f as screwed hole.Above-mentioned sluicing lid 18 has the diameter flange part 18a big, more rounded than the diameter of discharge opening 8, and is darted on the periphery wall of a side of this flange part 18a, can twists the external thread part g as the threaded portion that closes with above-mentioned internal thread f.
Thus, cover 18 external thread part g through sluicing and be screwed among the internal thread part f of discharge opening 8, sluice and cover 18 inaccessible discharge openings 8.Through adopting so-called screw lid structure, what do not have that water spills firm closes the bolt operation.Perhaps, take off through twisting that pulling down sluices covers 18, can open discharge opening 8 fully from discharge opening 8.
Along the circumferential direction be provided with a plurality of drainings that have the interval to each other with hole 22 sluicing cover on 18 the external thread part g.On the other hand, the internal thread part f of discharge opening 8 be provided with 1 opening size and above-mentioned draining with the roughly the same or little draining in hole 22 with groove 23.
The draining of discharge opening 8 is covered 18 and entirely shuts and be not communicated with hole 22 with draining on the position of discharge opening 8 sluicing with groove 23.Cover 18 obturations removed fully discharge opening 8 when rotate sluicing, making sluices again covers 18 openings to a certain degree the time, and draining is communicated with groove 23 with draining with hole 22.Therefore, the drainage water that discharges in the drain pans 7 with groove 23 with hole 22 and draining through draining.
If be not provided with draining with hole 22 and draining with groove 23, only cover 18 and make discharge opening 8 open and close structure freely with sluicing, then when pulling down sluicing from discharge opening 8 when covering 18, drainage water will be discharged from discharge opening 8 moment in a large number.Therefore, have to contain fully and transfer sluicing, the danger around getting wet, but therefore said structure can be contained down, around can not getting wet owing to draining at leisure fully.
Sealing gasket 20 is placed on to sluice and covers above 18 the flange part 18a, is fitted to the side face of external thread part g with having certain wide looseness.Be described in detail sealing gasket 20 below.
Fig. 5 (A) is the vertical view of sealing gasket 20, and Fig. 5 (B) is the cutaway view along the B-B line of Fig. 5 A.Fig. 6 is the amplification view of sealing gasket 20.
Above-mentioned sealing gasket 20 is made up of for example rubber composition, in order to keep high leakproofness, adopts the high material of coefficient of elasticity.Shown in Fig. 5 (A), sealing gasket 20 is overlooked rounded.Like Fig. 5 (B) and shown in Figure 6, the cross sectional shape of sealing gasket 20 forms approximate X word shape.In addition, comprise among the present invention that this cross sectional shape that forms the sealing gasket 20 of approximate X word shape is called cross section X word shape.
Be specially, sealing gasket 20 comprises root 20a that forms along the axle center and the 20b of limit portion that dashes forward and establish to 4 direction one at a predetermined angle from the side face of this root 20a.Wherein, to the left and right the outstanding 20b of the limit portion angle [alpha] each other of incline direction than the 20b of limit portion angle beta each other outstanding on the direction that upwards has a down dip big (α>β).
On the incline direction to the left and right of sealing gasket 20 among the outstanding 20b of limit portion one is placed on to sluice and covers on 18 the flange part 18a.Because outstanding limit portion 20b angle [alpha] each other forms greatly on the incline direction to the left and right, the posture of covering 18 sealing gaskets 20 when being screwed to discharge opening 8 that therefore sluices can not change good stability.And the top of each 20b of limit portion forms the cross section semicircle, covers 18 flange part 18a line state of contact held at this top with sluicing, and stability is better.
On the 20b of limit portion of side interior Monday of sealing gasket 20, lug boss 20c is set integratedly along the top of every 20b of limit portion.It is roughly semicircle that this lug boss 20c also is the cross section, side-prominent to the internal diameter one of sealing gasket 20.And, when being placed into, sealing gasket 20 sluices when cover 18 flange part 18a and going up, and lug boss 20c is relative with the butt of the external thread part g that covers 18 periphery wall as sluicing.
And the gauge La of the root 20a that forms along the axle center of above-mentioned sealing gasket 20 is formed 1/2～1/3L of whole height dimension L.The height dimension of each 20b of limit portion deducts the half the size of pact of difference of the gauge La of root 20a for overall height dimension L.
Fig. 1 of this structure is to the indoor set of air conditioner shown in Figure 3, and when blower 5, room air is sucked in the indoor set main body 1 by horn mouth 16 guiding with suction inlet 12 through sucking grid 13.Room air, is derived to a secondary side after the heat exchange through heat exchanger 6 from the elementary effluent of heat exchanger 6.
Then, heat exchange air blows out to indoor from blow-off outlet 15, the air in the conditioning chamber.Especially during refrigerating operaton, the drainage water droplet that generates along with the heat exchange action of heat exchanger 6 is in drain pan 7.As time goes on, the amount of the drainage water that converges in the drain pan 7 increases, and water level rises.
Do not have the switch of expression to detect the water level of drainage water in the drain pan 7 among the figure, when the water level that detects drainage water was above standard peak level, switch sent detection signal to control module always.Control module sends to drainage pump 10 and drives signal, and drainage pump 10 picks up drainage water, is discharged to the outside through discharge hose 19.
The drainage water that converges in the drain pan 7 does not overflow drain pan 7, successfully is discharged from.The water level that detects drainage water when switch descends gradually, when dropping to minimum datum level, sends detection signal to control module once more.Control module sends stop signal for drainage pump 10, stops to discharge drainage water.
When upkeep operation etc., remain under the situation that the drainage water in the drain pan 7 all discharges, pull down to sluice from discharge opening 8 and cover 18.
Be described in detail the operation that the sluicing lid 18 that possesses sealing gasket 20 opens and closes discharge opening 8 below.
Fig. 7 representes to pull down the state that 18 open discharge openings 8 are covered in sluicing from discharge opening 8, for discharge opening 8 covers a part of stereogram of 18 with sluicing.Fig. 8 representes cover with sluicing the state of 18 inaccessible discharge openings 8, covers the stereogram of a part of 18 for discharge opening 8 and sluicing.
As stated, the underside wall of drain pan 7 is provided with the discharge opening 8 that is used for discharging the drainage water that remains in the drain pan 7 when safeguarding drainage pump 10 grades.This discharge opening 8 has internal thread part f on internal perisporium, and is provided with a draining with groove 23.
Relative with it, sluicing is covered 18 and is possessed flange part 18a and external thread part g, and the sealing gasket 20 that the cross section forms the X word shape is placed on the flange part 18a.External thread part g is provided with a plurality of drainings that have predetermined space with hole 22.
As shown in Figure 7; The 20b of limit portion of bottom one side that the incline direction to the left and right of sealing gasket 20 is outstanding is placed on to sluice and cover on the flange part 18a, in the sealing gasket 20 Monday side the top of the outstanding 20b of limit portion of direction that upwards has a down dip be nested in the butt that 18 external thread part g is covered in sluicing with having wide looseness.
The side direction Monday top of the outstanding 20b of limit portion of incline direction up and down is provided with lug boss 20c in sealing gasket 20, and these lug bosses 20c is relative with the butt that covers 18 external thread part g of sluicing.Since only sealing gasket 20 in Monday side the 20b of limit portion on lug boss 20c is set, even therefore with sealing gasket 20 spin upside down being placed into sluicing cover on 18 the flange part 18a also no problem.That is,, therefore improved operating efficiency owing to need not confirm the installation direction of sealing gasket 20.
And the butt at the nearest external thread part g of the flange part 18a that covers 18 from sluicing along the circumferential direction is provided with depressed part 25.This depressed part 25 forms the cross section semicircle, be can with the chimeric size and dimension of lug boss 20c on the 20b of limit portion that is arranged on above-mentioned sealing gasket 20 integratedly.
As shown in Figure 8, make sluice cover 18 with discharge opening 8 relatively after, will sluice and cover external thread part g and be screwed among the discharge opening internal thread part f, rotating operation sluicing covers 18.Sealing gasket 20 is placed on to sluice at the 20b of right sides portion that keeps bottom one side and covers under the state on 18 the flange part 18a, and the 20b of right sides portion of top one side contacts with the underside wall of drain pan 7.
And when rotary manipulation sluicing covered 18, the gap of covering between flange part 18a and drain pan 7 underside walls that sluices narrowed down gradually.Top one side of sealing gasket 20 and the 20b of right sides portion of bottom one side bear extruding force, sealing gasket 20 make right sides portion 20b interval each other broaden ground strain.
Thereupon, the depressed part 25 that the lug boss 20c that especially is provided with on the top of the 20b of limit portion of bottom one side among Mondays the 20b of limit portion that side forms in the sealing gasket 20 enters into the butt setting of covering external thread part g of sluicing goes.
Under the state of complete fastening sluicing lid 18, top one side of sealing gasket 20 and the 20b of right sides portion of bottom one side open to greatest extent and contact with each other.Perhaps, near arriving each other position contacting soon.Simultaneously, the lug boss 20c on the limit portion 20b top of bottom one side embeds to sluice and covers in the depressed part 25 of external thread part g root.
So; The sealing gasket 20 that is the X word shape in the cross section is sandwiched in to sluice and covers under the state between flange part 18a and drain pan 7 underside walls; Top one side of sealing gasket 20 is covered flange part 18a with the 20b of right sides portion of bottom one side with sluicing and is closely contacted with drain pan 7 underside walls; Anti-fully sealing spills between discharge opening 8 and sluicing cover 18, can improve reliability.
Even sluice cover 18 be screwed into weak a little in the discharge opening 8, or because long-term the use under the situation that 18 situations that are screwed into of covering that sluice relax naturally; Because the cross sectional shape of sealing gasket 20 is the X word shape; Therefore the mutual elastic return of the 20b of limit portion about is got back to initial angle [alpha].That is, guarantee the sealing of sealing gasket 20.
And, in this state,, the lug boss 20c that is provided with on the sealing gasket 20 cover in the depressed part 25 that is provided with on 18 through being embedded to sluice, can reach the purpose that 18 sealing is covered in further raising sealing gasket 20 sealing sluicing, can obtain higher reliability.
Because the gauge La of the root 20a that will form along the axle center forms 1/2～1/3L of the overall height dimension L of above-mentioned sealing gasket 20; Therefore clipped under the state that is sluicing between the underside wall that covers flange part 18a and drain pan 7 at sealing gasket 20; Can guarantee to guarantee sealing as sealing gasket 20 necessary thickness.
For example, if the gauge La of root 20a is set at 1/2 big than the overall height dimension L of sealing gasket 20, then sealing gasket 20 can not obtain the necessary thickness of tightening, and has become unsettled sealing state.
And if the gauge La of root 20a is set at 1/3 little than the whole height dimension L of sealing gasket 20, then must exceedingly tightening sluices covers 18, still becomes unsettled sealing state.It more than is the conclusion that derives from the experimental result of carrying out repeatedly.
When drainage pump 10 was carried out upkeep operation, the counter-rotation operation sluiced and covers, and the lid that will sluice is pulled down from discharge opening 8.Sealing gasket 20 is also pulled down being placed into to sluice to cover under the state on 18 the flange part 18a.Owing to removed extruding force, therefore promptly returned to original cross section X word shape once more to sealing gasket 20.
And from adopt will sluice cover 18 be screwed into structure the discharge opening 8, the limit of sealing gasket 20 20b of lug boss 20c is set and with lug boss embed sluicing cover in the depressed part 25 of 18 settings and the gauge La of root 20a with respect to the conditions such as setting of sealing gasket 20 whole height L; Can expect more firm sealing, and obtain higher reliability.
In addition, the present invention also not exclusively is confined to above-mentioned example, the implementation phase can in the scope that does not break away from its aim, change the inscape practical implementation.And,, can form various invention schemes through the disclosed a plurality of inscapes of the above-mentioned example of appropriate combination.
