Have, heat exchanger 3 is configured to positive apparent time and is anti-Eight characters shape roughly again, in that when dripping, the main drain pan 6 of catching it is configured in the below of heat exchanger 3 attached to the moisture on it (long-pending dew etc.).In addition, heat exchanger (being equivalent to indoor heat converter) 3 compressor, outdoor heat converter and cold-producing medium expansion member on being arranged on the not shown off-premises station that goes out, cold-producing medium constitute freeze cycle, by changing flowing of cold-producing medium, as condenser (emitting warm), evaporimeter (emitting cold and hot) performance function.
(blowing out wind path)
Blowing out wind path 5 positive apparent times is roughly Γ (gamma) word shape roughly circular-arc or that have arc sections, by being configured in upside or away from a side of pressure fan 4, the major diameter that radius of curvature is bigger blows out wall (identical with the wind path wall) 12, is configured in downside or close pressure fan 4 one sides, radius of curvature blows out wall 12 little minor diameters than major diameter and blows out wall (identical with the wind path wall) 13, major diameter is blown out wall 12 is connected with the both ends that minor diameter blows out wall 13, and the end that forms crooked tube blows out wall 14 and forms.
In addition, below, for convenience, to blow out wind path 5 in scope near pressure fan 4, roughly be divided into and regulate air at the 5a of bottom horizontal flow sheet portion, the then 5a of bottom horizontal flow sheet portion, and the reformed circular-arc circular arc flow portion 5b of flow direction that general horizontal direction blows out, then circular arc flow portion 5b, and form towards the roughly vertical vertical flow portion 5c that flows of below until blow-off outlet 15, but border separately is not necessarily clearly demarcated.
Then, the 5a of bottom horizontal flow sheet portion is formed by the major diameter horizontal wall part 12a that major diameter blows out wall 12.Circular arc flow portion 5b by major diameter blow out the large diameter circular arc wall part 12b of wall 12 and with it in opposite directions the minor diameter minor diameter circular arc wall part 13b that blows out wall 13 form.In addition, vertically the flow portion 5c major diameter upright wall part that blows out wall 12 by major diameter divide 12c and with it in opposite directions the minor diameter minor diameter upright wall part that blows out wall 13 divide 13c to form.In addition, border separately is not necessarily clearly demarcated.
(the long-pending white water discharge portion of larger diameter side)
Among Fig. 2, major diameter blow out wall 12 discontiguous of adjusting air (be not that to blow out the face of face of wind path 5 identical, the face in left side is called " face of inverted ventilation trackside " in the following text among Fig. 2) form long-pending white water discharge portion 20.
Long-pending white water discharge portion 20 has slit-shaped openings portion 21 and long-pending dew dish 22, this slit-shaped openings portion 21 major diameter blow out wall 12 roughly be equivalent to form on the position on border that large diameter circular arc wall part 12b and major diameter upright wall part divide 12c, and long-pending dew freely passes through; Should long-pending dew dish 22 below slit-shaped openings portion 21, be set at major diameter and blow out on the face of inverted ventilation trackside of wall 12, and will be by slit-shaped openings portion 21, be immersed in the long-pending dew that major diameter blows out the inverted ventilation trackside of wall 12 and catch.
(the long-pending dew dish of larger diameter side)
Long-pending dew dish 22 is the tank shape (the case shape of top opening) that divides face, the plate 22a that tries to get to the heart of a matter, dish side plate 22b and the dish end plate 22c of inverted ventilation trackside of the part of 12c to form by the major diameter upright wall part.Dish side plate 22b is connected sleekly with the lower end (identical with the upper limb of slit-shaped openings portion 21) of large diameter circular arc wall part 12b.Therefore, can regard that the lower end of large diameter circular arc wall part 12b is extended sleekly to the below of inverted ventilation trackside as, the form that engages with the plate 22a that tries to get to the heart of a matter.
In addition, the upper limb of plate end plate 22c is in the position lower than the lower edge of slit-shaped openings portion 21.Therefore, blow out long-pending dew on the face of wind path side of wall 12 (especially large diameter circular arc wall part 12b) attached to major diameter, immerse the inverted ventilation tracksides, be stored in long-pending dew dish 22 by slit-shaped openings portion 21 along under this surface current.In view of the above, prevent long-pending dew from blow-off outlet 15 to indoor dripping (dew falls).
Divide at the major diameter upright wall part the secondary drain pan 7 that the moisture that blows out attached to major diameter on the face of inverted ventilation trackside of wall 12 is caught is set on the face of inverted ventilation trackside of 12c, the water that is stored in secondary drain pan 7 is by not shown draining road direction master drain pan 6 guiding that go out.
Then,, then should flow into secondary drain pan 7 by long-pending dew,, be directed to main drain pan 6 via draining road (not shown go out) if the long-pending dew that flow into long-pending dew dish 22 overflows from the upper limb of dish end plate 22c.Have again, the moisture (situation that does not contain long-pending dew is also arranged) that is stored in main drain pan 6 by the not shown discharge member that goes out to the not shown guiding such as off-premises station that go out.
In addition, the form that the present invention will not amass dew dish 22 is defined in illustrated form, for example, also can remove dish end plate 22c, long-pending dew is flowed out from the end of the plate 22a that tries to get to the heart of a matter, also can remove long-pending dew dish 22 itself, make long-pending dew flow directly into secondary drain pan 7 (at this moment, long-pending dew is not stored (accumulating) at long-pending dew dish 22).Perhaps, also the long-pending dew that is stored in long-pending dew dish 22 directly can be guided to main drain pan 6 without secondary drain pan 7.
(the long-pending white water discharge portion of smaller diameter side)
On the other hand, on blowing out the face of inverted ventilation trackside of wall 13, minor diameter forms long-pending white water discharge portion 30.
Long-pending white water discharge portion 30 has slit-shaped openings portion 31 and long-pending dew dish 32, this slit-shaped openings portion 31 minor diameter blow out wall 13 roughly be equivalent to form on the position on border that minor diameter circular arc wall part 13b and minor diameter upright wall part divide 13c, and long-pending dew freely passes through; Should long-pending dew dish 32 will be by slit-shaped openings portion 31, be immersed in the long-pending dew that minor diameter blows out the inverted ventilation trackside of wall 13 and catch.
(the long-pending dew dish of smaller diameter side)
Long-pending dew dish 32 divides the face of the inverted ventilation trackside of 13c, the plate 32a that tries to get to the heart of a matter, dish side plate 32b and dish end plate 32c to form by the minor diameter upright wall part.Dish side plate 32b is connected sleekly with the lower end (identical with the upper limb of slit-shaped openings portion 31) of minor diameter circular arc wall part 13b.Therefore, can regard that the lower end of minor diameter circular arc wall part 13b is extended sleekly to the below of inverted ventilation trackside as, the form that engages with the plate 32a that tries to get to the heart of a matter.In addition, the upper limb of plate end plate 32c is in the position lower than the lower edge of slit-shaped openings portion 31.
Therefore, blow out long-pending dew on the face of wind path side of wall 13 (minor diameter circular arc wall part 13b) attached to minor diameter,, immerse the inverted ventilation trackside, be stored in long-pending dew dish 32 by slit-shaped openings portion 31 along under this surface current.In view of the above, prevent long-pending dew from blow-off outlet 15 to indoor dripping (dew falls).
Divide at the minor diameter upright wall part on the face of inverted ventilation trackside of 13c secondary drain pan 8 is set, same with the long-pending white water discharge portion 20 of larger diameter side, the long-pending dew that overflows from the upper limb of the dish end plate 32c of long-pending dew dish 32 flows into secondary drain pan 8, by not shown draining road direction master drain pan 6 guiding that go out.
In addition, the present invention is limited to this point of illustrated form with to amass dew dish 32 identical in the form that will not amass dew dish 32.
As mentioned above because indoor set 100 will guide outside wind path blowing out the long-pending dew that wind path 5 produces, so, prevent long-pending dew from blow-off outlet 15 to indoor dripping (dew falls).Because blow out in major diameter and do not upset distinguished and admirable projection (prominent bar) on the wall 12,13 this moment, so, there is not distinguished and admirable situation about being hindered, guarantee energy-saving operation.
In addition, because it is obvious to think that the major diameter attached to the adjusting air collision of sending from pressure fan 4 of amassing dew blows out wall 12 sides, so indoor set 100 also can remove the long-pending white water discharge portion 30 of smaller diameter side, only has the long-pending white water discharge portion 20 of larger diameter side.
(variation of slit-shaped openings portion)
Among Fig. 3, though film 23 coverings by by (soaking into) long-pending dew, saturating are not wetly soaked into by what (say so exactly be difficult to by) regulated air in slit-shaped openings portion 21.At this moment, the face of saturating wet wind path side of soaking into film 23 divides the face of the wind path side of 12c to be connected smoothly with the major diameter upright wall part in the face of the wind path side of large diameter circular arc wall part 12b.
Therefore, owing to the flowing of air that blows out in the wind path 5 further do not upset, so, can further guarantee energy-saving operation.
(variation of dish sidewall)
Among Fig. 4, extend smoothly to the below of inverted ventilation trackside the lower end of large diameter circular arc wall part 12b, forms large diameter circular arc wall prolongation (being equivalent to penthouse) 12d, does not continue with dish side plate 22b in its lower end.Therefore, the former the lower edge of extension and the upper limb of dish side plate 22b between form gap 25.Then, the upper limb height of the upper limb of dish side plate 22b and dish end plate 22c is roughly the same.Therefore, both overflow (say so exactly from the dewatering orifice 24 flow out) from the upper limb of the upper limb of dish side plate 22b and dish end plate 22c to be full of long-pending dew that the back flows at long-pending dew, are caught by secondary drain pan 7.
In addition, large diameter circular arc wall prolongation 12d cover long-pending dew dish 22 the top, promptly, the lower end of large diameter circular arc wall prolongation 12d (calling " extension lower end " in the following text) 12e compares with the dish side plate 22b of long-pending dew dish 22 and is arranged in inverted ventilation trackside (figure left side).Have again, below large diameter circular arc wall prolongation 12d, the scope that directly over long-pending dew dish 22, is comprised (among the figure, with dish side plate 22b vertically directly over the right side compared) form prominent bar 26.
Therefore, even produce dewfall outside blowing out wind path 5, and the surface current moisture down that blows out the inverted ventilation trackside of wall 12 along major diameter drips from the extension lower end 12e of large diameter circular arc wall prolongation 12d, also do not have this moisture interior situation of long-pending dew dish 22 of dripping.In addition, blowing out in the wind path 5 at long-pending white water and to produce, and passing through under the situation of slit-shaped openings portion 21 along the surface current long-pending dew down of the wind path side of large diameter circular arc wall part 12b, mobile below large diameter circular arc wall prolongation 12d, drip from prominent bar 26, amassed dew dish 22 to catch.

(indoor set of air conditioner)
Fig. 5 and Fig. 6 are the figure of indoor set of the air conditioner of the relevant embodiments of the present invention 2 of explanation, (a) of Fig. 5 amplifies the partial sectional view that the master that represents looks with the part of air conditioner, (b) of Fig. 5 is the partial sectional view that the part of air conditioner is amplified the side-looking of representing, Fig. 6 is the flow chart of the control flow of expression indoor set.In addition, each figure is the figure that schematically draws, and the present invention is not limited to illustrated mode (aspect ratio of component parts, thickness etc.).In addition, to part identical or the suitable identical symbol of part mark, clipped explanation with embodiment 1.
Among Fig. 5, the indoor set of air conditioner (following also have the situation that abbreviates " indoor set " as) the 200th is in the indoor set shown in the embodiment 1 100, possess the detection means of the generation that detects long-pending dew and according to the testing result of this detection means, prevent the indoor set of control member of the generation of long-pending dew.In addition, to part identical or the suitable identical symbol of part mark, clipped explanation with embodiment 1.
(the long-pending white water discharge portion of larger diameter side)
Among Fig. 5, on the long-pending dew dish 22 of indoor set 200, level sensor 80 is set.At this moment, the plate 22a that tries to get to the heart of a matter tilts in the mode that reduces to a dish end plate 22c, near formation dewatering orifice (be equivalent to be detained and prevent member) the 27 dish end plate 22c of the plate 22a that tries to get to the heart of a matter.In addition, level sensor 80 is set near dewatering orifice 24.
Therefore, in indoor set 200, even the position arbitrarily of the width of circular arc flow portion 5b (especially) produces long-pending dew in the position arbitrarily that blows out wind path 5, it also flows into long-pending dew dish 22.So, flowing to level sensor 80 directions, the generation of long-pending dew is than under the situation of Duoing from the amount of dewatering orifice 24 outflows, and long-pending dew is stored in long-pending dew dish 22 (water yield increase).If finally fill, then the upper limb from a dish end plate 22c overflows, and 16 flow into secondary drain pan 7 through the draining road.

The interval that level sensor 80 possesses the regulation of being provided with in opposite directions pair of conductive body 80a, 80b and under long-pending dew is immersed between the two situation, detect between the two resistance or the detection means of the variation of static capacity (not shown go out).In addition, the present invention does not limit its form, flow near situation of (being present in) dewatering orifice 24 or the parts that long-pending dew is stored near (accumulating) situation dewatering orifice 24 so long as can detect long-pending dew, can be (for example, optical profile type etc.) arbitrarily.
Therefore, if reduce the detection position (for example, if set in advance on the plate 22a that tries to get to the heart of a matter) of level sensor 80 in advance, then under the few situation of the generation of long-pending dew, also can its generation of earlier detection.At this moment, also can remove a dish end plate 22c and dewatering orifice 24.
On the other hand, if set the detection position of level sensor 80 high in advance, then, can detect its generation only in (under the more situation of the rate of outflow (discharge of each unit interval) of dewatering orifice 24) under the bigger situation of the generation speed (generation of each unit interval) of long-pending dew.That is, prevent the flase drop survey, and also prevent the control that frequently prevents to produce long-pending dew described later, can not hinder comfortableness.
In addition, above-mentioned in, the plate 22a that tries to get to the heart of a matter tilts to an end, still, the present invention is not limited thereto, and also can tilt (making chevron) to both ends, and dewatering orifice 24 is set at two ends.In addition, also can make the peripheral recesses (will describe in detail separately) of dewatering orifice 24 to this.
Have again, also can the place of water level sensor, the SEA LEVEL VARIATION sensor (will describe in detail separately this) of the variation that detects the water level that stores near (accumulating) long-pending dew dewatering orifice 24 is set.
(control member)
Control member (not shown go out) when level sensor 80 detects long-pending dew and flows into long-pending dew dish 22, improve the cold-producing medium that heat exchanger 3 supplies with evaporating temperature (below comprise " indoor heat converter temperature ", as " evaporating temperature ".), after this, level sensor 80 is detecting long-pending dew when long-pending dew dish 22 flows out, and carries out the control of the evaporating temperature (turning back to original) that reduces the cold-producing medium that heat exchanger 3 supplies with.Below, according to flow chart (each step is represented with " S "), control flow is described.
(control flow)
Among Fig. 6, when the control member of indoor set 200 begins (ON) at cooling operation (S1), confirm cooling operation (S2), and the testing result of reference level sensor 80 (S3).Then, do not detect under the situation of long-pending dew (being recited as OFF among the figure), be judged as the not generation (S4) of long-pending dew, do not carry out the action (S5) of the generation that prevents long-pending dew, return step 2 at level sensor 80.At this moment, can return continuously, also can return at each certain hour.
On the other hand, detect under the situation of long-pending dew (among the figure, being recited as ON) at level sensor 80, the time (duration Hm) of the lasting above-mentioned action of reference (S6).Then, (Hm＜H1), be judged as long-pending dew dish 22 and do not fill water (S7) carries out above-mentioned action and (begins to carry out or continue and carry out, S8), return step 2 under the situation of not passing through stipulated time H1.
On the other hand, passed through at the duration Hm of above-mentioned action that (H1≤Hm), be judged as long-pending dew dish 22 and fill water (S9), being judged as above-mentioned action does not have effect, stops cooling operation (OFF) (S10) under the situation of stipulated time H1.At this moment, also can pass through demonstrations such as sound, character and graphic, inform that above-mentioned action does not have effect.
(action)
The action that prevents the generation of long-pending dew is the action that improves the temperature of the cold-producing medium of heat exchanger 3 supplies.In addition, also be the action that increases the rotating speed of pressure fan 4.Or carry out both actions simultaneously.
At this moment, because long-pending dew is that (heat exchanger 3 is as evaporimeter performance function under the situation of cooling operation, emit under the cold and hot situation) produce, so, though this action is to the directive effect that weakens refrigeration,, the temperature rising of cold-producing medium is small (for example, 1 ℃), therefore, will feel that uncomfortable situation prevents minimum.In addition, the main points that improve the temperature of cold-producing medium are known, reduce the rotating speed of the compressor of cold-producing medium, or change the throttle rate of cold-producing medium expansion member.
Have again, also can electric heater be switched on blowing out the electric heater that temperature that wind path 5 (especially circular arc flow portion 5b) is provided for making wall rises.At this moment, and if with one of above-mentioned action or both, then effect increase.
(the long-pending white water discharge portion of smaller diameter side)
Though indoor set 200 is the generations that detect long-pending dew in the long-pending white water discharge portion 20 of larger diameter side, but, the present invention is not limited thereto, even, also can detect the generation of long-pending dew equally the long-pending white water discharge portion 30 of smaller diameter side (being provided with under the situation of long-pending white water discharge portion 30 of smaller diameter side).At this moment, at the long-pending white water discharge portion 30 of the long-pending white water discharge portion 20 of larger diameter side and smaller diameter side the two, with reference to testing result, satisfy the one person under the situation of Rule of judgment, carry out (or stopping) above-mentioned action.
As mentioned above, in the indoor set 200, even produced long-pending dew in the position arbitrarily that blows out wind path 5, it also flows into and is arranged on the outer long-pending dew dish 22 of wind path, and its generation is carried out action by earlier detection.Therefore, the generation of long-pending dew is inhibited, prevent more effectively long-pending dew from blow-off outlet 15 to indoor dripping (dew falls).At this moment, same with indoor set 100, guarantee energy-saving operation.
In addition, though as mentioned above, indoor set 200 is the indoor sets that are provided with level sensor 80 at long-pending dew dish 22, but, also can remove long-pending dew dish 22, along the upper limb of slit-shaped openings portion 31 or lower edge one or both, on the face of the inverted ventilation trackside of wind path wall 12, level sensor 80 is set, when it detects long-pending dew and has passed through slit-shaped openings portion 31, carry out above-mentioned action, after this, when level sensor 80 detects the minimizing of the long-pending dew by slit-shaped openings portion 31 or disappears, stop above-mentioned action.

(indoor set of air conditioner)
Fig. 7 and Fig. 8 are the figure of indoor set of the air conditioner of the relevant embodiments of the present invention 3 of explanation, and Fig. 7 is the partial sectional view that the part of air conditioner is amplified the side-looking of representing, Fig. 8 is the flow chart of the control flow of expression indoor set.In addition, each figure is the figure that schematically draws, and the present invention is not limited to illustrated mode (aspect ratio of component parts, thickness etc.).In addition, to part identical or the suitable identical symbol of part mark, clipped explanation with embodiment 1.
Among Fig. 7, the indoor set of air conditioner (following also have the situation that abbreviates " indoor set " as) the 300th, the long-pending dew dish 22 in the indoor set shown in the embodiment 2 200 are provided with long-pending dew pit 40, are provided with the indoor set of a pair of level sensor 80 at long-pending dew pit 40.
That is, the end the low side of the long-pending dew dish 22 that tilts forms the long-pending dew pit 40 as recess that is absorbed in into cup-shaped, and 40a forms dewatering orifice 24 at the bottom of the pit of long-pending dew pit 40.Then, the position of 40a is provided with level sensor 80 (calling " level sensor 81 " in the following text) at the bottom of close the pit of the pocket wall 40c that is respectively at long-pending dew pit 40, in the position of the upper limb of the close pocket wall 40c that amasss dew pit 40 level sensor 80 (calling " full-water level sensor 82 " in the following text) is set.
Therefore, amassed the long-pending dew pit 40 of long-pending dew immersion that dew dish 22 is caught.At this moment, because the sectional area parallel with horizontal plane of the sectional area specific volume dew dish 22 parallel with horizontal plane of long-pending dew pit 40 is little, so even under the few situation of the generation of long-pending dew, the water level that is immersed in the long-pending dew of long-pending dew pit 40 also rises rapidly.That is, can be with the generation of the long-pending dew of " amplification " state-detection.
In addition, owing to the upper limb of the long-pending dew that arrives full-water level sensor 82 from pocket wall 40c overflows, so full-water level sensor 82 is as the sensor performance function that detects full waters.Therefore, owing to " reference of duration (S6) " in the control flow of indoor set 200 can be replaced into " detection of the long-pending dew in the full-water level sensor 82 (ON) ", so indoor set 300 can access the action effect same with indoor set 200.
In addition, though indoor set 200 has long-pending dew pit 40,, the present invention is not limited thereto, even remove long-pending dew pit 40, at the upper limb that coils side plate 22b full-water level sensor 82 is set, and also can access same action effect.
In addition, the shape of long-pending dew pit 40 is not defined.For example, also can be that the upper limb that amasss the pocket wall 40c of dew pit 40 is positioned at than the low position of plate 22a of trying to get to the heart of a matter.On the other hand, under the situation of the upper limb of the pocket wall 40c position higher than the upper limb of dish end plate 22c or dish side plate 22b, the upper limb of dish end plate 22c or dish side plate 22b is certainly discharged member performance function as full water.
(control flow)
Among Fig. 8, when the control member of indoor set 300 begins (ON) at cooling operation (S1), confirm cooling operation (S2), and the testing result (S3) of the following level sensor 81 of reference.Then, do not detect under the situation of long-pending dew (OFF), be judged as the not generation (S4) of long-pending dew, do not carry out the action (S5) of the generation that prevents long-pending dew, return step 2 at following level sensor 81.At this moment, can return continuously, also can return at each certain hour.
On the other hand, detect under the situation of long-pending dew (ON), with reference to the testing result of full-water level sensor 82 (S6 2) at following level sensor 81.Then, do not detect at full-water level sensor 82 under the situation of long-pending dew (OFF), being judged as at long-pending dew pit 40 has long-pending dew (S7), carries out above-mentioned action and (begins to carry out or continue and carry out, S8), return step 2.
Have, the two detects under the situation of long-pending dew (ON) at following level sensor 81 and full-water level sensor 82, is judged as long-pending dew pit 40 and is full water (S9) again, and being judged as above-mentioned action does not have effect, stops cooling operation (OFF) (S10).

(indoor set of air conditioner)
Fig. 9 and Figure 10 are the figure of indoor set of the air conditioner of the relevant embodiments of the present invention 4 of explanation, and Fig. 9 is the partial sectional view that the part of air conditioner is amplified the side-looking of representing, Figure 10 is the flow chart of the control flow of expression indoor set.In addition, each figure is the figure that schematically draws, and the present invention is not limited to illustrated mode (aspect ratio of component parts, thickness etc.).In addition, to part identical or the suitable identical symbol of part mark, clipped explanation with embodiment 1.
Among Fig. 9, the indoor set of air conditioner (following also have the situation that abbreviates " indoor set " as) the 400th is arranged to the full-water level sensor 82 in the indoor set 300 shown in the embodiment 3 to leave the indoor set of upper limb of the pocket wall 40c of long-pending dew pit 40.
Promptly, end the low side of the long-pending dew dish 22 that tilts, the long-pending dew pit 40 that dewatering orifice 24 is formed on 40a at the bottom of the pit is set, the position of 40a is provided with level sensor 80 (calling " following level sensor 81 " in the following text) at the bottom of the close pit of the pocket wall 40c that amasss dew pit 40, than following level sensor 81 high positions level sensor 80 (calling " full-water level sensor 82 " in the following text) is being set.
Therefore, the long-pending dew of being caught by long-pending dew dish 22 flows into long-pending dew pit 40, under the many situations of the discharge rate of each unit interval that the inflow ratio of each unit interval of amassing dew is discharged from dewatering orifice 24, at first, detect the long-pending dew (ON) of existence by following level sensor 81, then, detect the long-pending dew (ON) of existence by last level sensor 83.
So, owing to be that the influx of each unit interval of the long-pending dew of expression is many soon to last level sensor 83 from following level sensor 81, therefore, enlighten out the action that is necessary the generation that prevents to amass dew and strengthen for the time of ON for ON.
In addition, substitute and to descend level sensor 81 and last level sensor 83 to be arranged to two-stage,, also can access same action effect (, will describe in detail separately) this even a SEA LEVEL VARIATION sensor is set.
(control flow)
Among Figure 10, when the control member of indoor set 400 begins (ON) at cooling operation (S1), confirm cooling operation (S2), and with reference to the testing result of level sensor 81 down (S3 2).Then, do not detect under the situation of long-pending dew (OFF), be judged as the not generation (S4) of long-pending dew, do not carry out the action (S5) of the generation that prevents long-pending dew, return step 2 at following level sensor 81.At this moment, can return continuously, also can return at each certain hour.
On the other hand, detect under the situation of long-pending dew (ON) testing result of level sensor 83 in the reference (S6 3) at following level sensor 81.Then, do not detect under the situation of long-pending dew (OFF) at last level sensor 83, being judged as is the generation initial stage (S7 2) of long-pending dew, carries out first action (begin to carry out or continue and carry out, S8 2), returns step 2.
Have again, following level sensor 81 and on level sensor 83 the two detect under the situation of long-pending dew (ON), be the elapsed time of ON (water surface rise time Tm) (S6 4) with reference to being ON from level sensor 81 down to last level sensor 83.
Then, (during Tm＜T1), the generation that is judged as long-pending dew is (S7 3) more rapidly, carries out and second move (S8 3), returns step 2 at the flow judgement time T1 of the not enough regulation of water surface rise time Tm.
In addition, then, more than the flow judgement time T1 that water surface rise time Tm is stipulating, under the situation of the full water judgement time T2 of not enough regulation (T1≤Tm＜T2), the generation that is judged as long-pending dew is (S7 4) relatively slowly, carries out first action (S8 2), returns step 2.
Have again, at water surface rise time Tm in that (under the situation of T2≤Tm), be judged as long-pending dew pit 40 full waters (S9), being judged as above-mentioned action does not have effect, stops cooling operation (OFF) (S10) more than the full water judgement time T2 of regulation.
(second action)
The length of water surface rise time after second action is moved according to execution first is selected.That is, because the number of the generation of each unit interval of the long-pending dew of this water surface rise time reflection, so the expression water surface rise time is short more, the generation of each unit interval of long-pending dew is many more.
Therefore, water surface rise time Tm is called second action than the action under the short situation of official hour, is in a ratio of brute force (for example, the evaporating temperature of cold-producing medium being risen 2 ℃ or 3 ℃) with first action (for example, the evaporating temperature of cold-producing medium being risen 1 ℃).Perhaps, also can determine the intensity (for example, the ascending amount of the evaporating temperature of cold-producing medium) of second action by the function of water surface rise time.
In addition, the quantity that is provided with of level sensor 80 of the present invention is not limited to 2, and the full water sensor 83 in the indoor set 300 (embodiment 3) also can be set, and adds up to 3.At this moment, the judgement of full water can substitute the situation (T2≤Tm), in addition read into full water sensor 83 be the situation of ON of water surface rise time Tm more than the full water judgement time T2 of regulation.

(indoor set of air conditioner)
Figure 11 and Figure 12 are the figure of indoor set of the air conditioner of the relevant embodiments of the present invention 5 of explanation, and Figure 11 is the partial sectional view that the part of air conditioner is amplified the side-looking of representing, Figure 12 is the flow chart of the control flow of expression indoor set.In addition, each figure is the figure that schematically draws, and the present invention is not limited to illustrated mode (aspect ratio of component parts, thickness etc.).In addition, to part identical or the suitable identical symbol of part mark, clipped explanation with embodiment 1.
Among Figure 11, the indoor set of air conditioner (following also have the situation that abbreviates " indoor set " as) the 500th, the following level sensor 81 in the indoor set 400 shown in the alternate embodiments 4 and go up level sensor 83, SEA LEVEL VARIATION sensor 90 is arranged on the pocket wall 40c of long-pending dew pit 40, and full-water level sensor 82 is arranged near the indoor set the upper limb of pocket wall 40c.
That is, because be the indoor set of the pace of change (rate of climb, decrease speed or water surface elevation do not change) of SEA LEVEL VARIATION sensor 90 water surface that can detect long-pending dew, so, by a sensor, can access the action effect same with indoor set 400.
(control flow)
Among Figure 12, when the control member of indoor set 500 begins (ON) at cooling operation (S1), confirm cooling operation (S2), and the testing result of reference level change sensor 90 (S3 2).
Then, there is not to detect variation (below be called " the water surface rising velocity ") Vm (Vm=0) of the water surface elevation of long-pending dew at SEA LEVEL VARIATION sensor 90, also do not carry out (the judgement time H2 of the not enough regulation of duration Hm under the situation of moving, Hm＜H2), being judged as long-pending dew does not have to produce or the incunabulum (S4) of generation, do not carry out the action (S5) of the generation that prevents long-pending dew, return step 2, continuously repeatedly.
In addition, the water surface rising velocity Vm (Vm=0) that does not have to detect long-pending dew at SEA LEVEL VARIATION sensor 90, duration Hm has passed through under the situation of judgement time H2 of regulation (H2≤Hm), because long-pending dew pit 40 becomes the state (S9) of full water, so, being judged as above-mentioned second action does not have effect, stops cooling operation (OFF) (S10).
On the other hand, detect under the situation that the water surface of long-pending dew rises at SEA LEVEL VARIATION sensor 90 that (0≤Vm), being judged as is initial stage of producing of long-pending dew (S7 3), carries out action (S8), returns step 2.At this moment, also can be according to the size of water surface rising velocity Vm, the intensity of change action.For example, under the little situation of the rate of climb V1 of water surface rising velocity Vm ratio regulation, the generation of regarding each unit interval of amassing dew as is fewer, reduce the ascending amount (for example, 1 ℃) of evaporating temperature, on the other hand, under the big situation of the rate of climb V1 of water surface rising velocity Vm ratio regulation, the generation of regarding each unit interval of amassing dew as is many, increases the ascending amount (for example, 3 ℃) of evaporating temperature.Perhaps, also can decide the ascending amount of evaporating temperature according to the function of water surface rising velocity Vm.
Have, detect under the situation that the water surface of long-pending dew descends (Vm＜0) at SEA LEVEL VARIATION sensor 90, the generation end or the generation that are judged as long-pending dew are trace (S4), stop action (S5), return step 2.
In addition, above-mentioned is to judge that by the duration Hm that carries out after moving long-pending dew pit 40 becomes the state of full water, still, also can substitute it, near the upper limb of pocket wall 40c, set up full-water level sensor 82 (referring to embodiment 3), in view of the above, whether detect full water.

(indoor set of air conditioner)
Figure 14 and Figure 15 are the figure of indoor set of the air conditioner of the relevant embodiments of the present invention 7 of explanation, and Figure 14 is the partial sectional view that the part of air conditioner is amplified the side-looking of representing, Figure 15 is the flow chart of the control flow of expression indoor set.In addition, each figure is the figure that schematically draws, and the present invention is not limited to illustrated mode (aspect ratio of component parts, thickness etc.).In addition, to part identical or the suitable identical symbol of part mark, clipped explanation with embodiment 1.
Among Figure 14, the indoor set of air conditioner (following also have the situation that abbreviates " indoor set " as) the 700th is in indoor set 400 (embodiment 4), forming the dewatering orifice indoor set of (be equivalent to delay and prevent member, call " wall dewatering orifice 44 " in the following text) down between level sensor 81 and the full-water level sensor 82.
In indoor set 200～indoor set 700, owing to regulate air by air cleaner 2, dust etc. are removed, so, prevent the situation that dewatering orifice (calling " dewatering orifice, the end " in the following text) 24 is blocked.But under the situation of having blocked in dewatering orifice, the end 24 for some reason, to be judged as long-pending dew dish 22 or long-pending dew pit 40 become full water state, and the possibility that stops cooling operation can not saying fully do not have.
Therefore, in indoor set 700, between level sensor (calling " following level sensor " in the following text) 81 and level sensor (calling " going up level sensor " in the following text) 82, form wall dewatering orifice 44, even under the situation of supposing to have sealed in dewatering orifice, the end 24, also cooling operation can be do not stopped, the action of the generation that prevents long-pending dew can be carried out.
(control flow)
Among Figure 15, when the control member of indoor set 700 begins (ON) at cooling operation (S1), confirm cooling operation (S2), and the testing result (S3) of the following level sensor 81 of reference.Then, do not detect under the situation of long-pending dew (OFF), be judged as the not generation (S4) of long-pending dew, do not carry out the action (S5) of the generation that prevents long-pending dew, return step 2 at following level sensor 81.At this moment, can return continuously, also can return at each certain hour.
On the other hand, detect under the situation of long-pending dew (ON) at following level sensor 81, the testing result of the long-pending dew of level sensor 83 in the reference (S3 2), and with reference to the elapsed time (calling " sensor elapsed time Sm " in the following text) that begins for ON from level sensor 81 down (S6 3).
Then, do not detect long-pending dew (OFF) at last level sensor 83, and under the situation of sensor elapsed time Sm than the sensor judgement time S1 weak point of regulation (Sm＜S1), be not judged as and block, it is the generation initial stage (S7 1) of long-pending dew, carrying out action (begins to carry out or continues and carry out, S8), return step 2.
In addition, do not detect long-pending dew (OFF) at last level sensor 83, and under the situation of sensor elapsed time Dm than the sensor judgement time S1 length of regulation (S1≤Sm), irrelevant with the generation of not amassing dew, be judged as dewatering orifice, the end 24 and block (S7 5), stop action (S5), return step 2.
Have again, detect long-pending dew (ON) at last level sensor 83, and under the situation of sensor elapsed time Sm than the sensor judgement time S1 weak point of regulation (Sm＜S1), though being judged as dewatering orifice, the end 24 blocks, but, be the generation initial stage (S7 6) of long-pending dew, carry out action (S8), return step 2.
In addition, detect long-pending dew (ON) at last level sensor 83, and sensor elapsed time Sm is than (S1≤Sm), be judged as dewatering orifice, the end 24 and block under the long situation of the sensor judgement time S1 of regulation, long-pending dew pit 40 is full water state (S9), stops cooling operation (OFF) (S10).
In addition, because under the state of dewatering orifice, the end 24 and wall dewatering orifice 44 the two obstructions, can not proceed cooling operation, so, also can measure the duration that detects long-pending dew (ON) beginning from last level sensor 83, surpassed in this duration under the situation of the judgement time of stipulating, informed " dewatering orifice, the end 24 and wall dewatering orifice 44 the two obstructions ".
Therefore, even indoor set 700 under the situation of dewatering orifice, the end 24 obstructions, also can be carried out the action of the generation that prevents long-pending dew.
In addition, the configuration of the level sensor 80 in the indoor set 700 is not limited to diagram like that.For example, also can the scope under the wall dewatering orifice 44 or on the one or both of scope one or more level sensor 80 or SEA LEVEL VARIATION sensor 90 or static capacity sensor 70 are set.Have, also can make wall dewatering orifice 44 is more than two, and one or more level sensor 80 etc. is set betwixt again.
