Discharge in condensed water outside to indoor set 100 under the effect of draining pump 200 that drain pan 260 is assembled.In order to utilize draining pump 200 condensed water is discharged the drainpipe connecting portion 240 that will illustrate to the outside of indoor set 100 below a side of casing 140 is connected with.And, in a side of casing 140, promptly be formed with the connecting hole 240 ' that is connected with drainpipe connecting portion 240 in the side perforation that draining pump 200 is installed.
In addition, on draining pump 200, connect draining tubule 220.One end of draining tubule 220 is communicated with draining pump 200, and the other end is communicated with tubule connecting portion 244.The soft material of draining tubule 220 usefulness is made, and has certain elasticity, to the exterior guiding condensed water of indoor set.
And, the hose transition 242 of the scupper hose that below the another side of connecting plate 246 forms promising connection, will illustrate (not shown).Hose transition 242 is connected with scupper hose, and direct condensed water makes the flows outside of condensed water to casing 140.
That is, drainpipe connecting portion 240 is formed with tubule connecting portion 244 in a side, is formed with hose transition 242 at opposite side.And, between tubule connecting portion 244 and hose transition 242, being formed with connecting plate 246, connecting plate 246 utilizes screw to be fixed on the casing 140, and drainpipe connecting portion 240 is fixed on the casing 140.
In the end of hose transition 242, promptly at the opposite side of scupper hose connection, connecting plate 246 is one-body molded with hose transition 242.Connecting plate 246 is roughly quadrangle form, is formed with the condensation water hole 248 that hose transition 242 and tubule connecting portion 244 are communicated with about the central part perforation greatly.
That is, at the middle part of connecting plate 246, hose transition 242 forms so that certain-length is outstanding to a side, and an end of hose transition 242 is connected with scupper hose (not shown), and the other end is communicated with the condensation water hole 248 of connecting plate 246.
In addition, perforation is formed with screw hole 246 ' on each angle of connecting plate 246, can utilize screw connecting plate 246 to be fixed on a side of casing 140.
In the another side of connecting plate 246, promptly in the another side that is formed with hose transition 242, the tubule connecting portion 244 that is connected with draining tubule 220 is to the outstanding formation in side.Tubule connecting portion 244 has the diameter relatively little than hose transition 242, and inner circumferential surface is communicated with the condensation water hole 248 at connecting plate 246 middle parts.
At the middle part of tubule connecting portion 244, give prominence to the formation limit along outer peripheral face perpendicular to the direction of tubule connecting portion 244 and connect projection 244 '.It is in the socket boundary of draining tubule 220 along the outer peripheral face of tubule connecting portion 244 draining tubule 220 during in the length direction socket that limit connects projection 244 '.Like this, the socket degree by accurate grasp draining tubule 220 reduces time loss unnecessary in assembling procedure, and the socket length of restriction draining tubule 220.
In addition, on tubule connecting portion 244, also be formed with non-slip process 244 ".Non-slip process 244 " after the outer peripheral face of tubule connecting portion 244 is crooked upward, be bent downwardly moulding more at a certain angle gradually, its crooked upward rising height limits that to connect projection 244 ' smaller relatively.Draining tubule 220 is along the outer peripheral face of tubule connecting portion 244 non-slip process 244 along the inclination moulding when length direction connects " connect.By outstanding height expansion, make the draining tubule 220 of soft material draining tubule 220 produce certain elastic force, prevent the slip of draining tubule 220 thus to the inner peripheral surface direction.
Therefore, drainpipe connecting portion 240 is the center with the condensation water hole 248 of connecting plate 246, is formed with hose transition 242 in a side, is formed with tubule connecting portion 244 in the another side.Hose transition 242 and tubule connecting portion 244 and condensation water hole 248 all are interconnected, so condensed water can be discharged to the outside from the inside of indoor set 100.
And, at the anti-locking apparatus 300 of internal configurations backflow of tubule connecting portion 244.The anti-locking apparatus 300 that refluxes comprises: at the tubule connecting portion 244 inner annulus through holes 320 that form; The inside that connects its annulus through hole 320 forms and controls lift valve (Poppet) 340 formations of the mobile direction of condensed water.
The ring body of annulus through hole 320 has certain thickness, and is fixed on the inner peripheral surface of tubule connecting portion 244.Lift valve 340 connects the middle part that is connected annulus through hole 320.Lift valve 340 comprises the flow lifting head 342 of direction and constitute in the inner peripheral surface pistons reciprocating portion 344 of annulus through hole 320 of direct control condensed water.
The left surface (see figure 6) of annulus through hole 320 can engage with the right flank (see figure 6) of lifting head 342.That is, if piston portion 344 moves the side to the right, the right flank of lifting head 342 closely contacts with the left surface of annulus through hole 320.
More detailed description, the left surface of lifting head 342 are smooth circular plate shape, and prolong formation along the circumferential right side side of left surface.Tilt to the inner peripheral surface direction when in addition, the side prolongs to the right.Promptly from the left surface of lifting head 342 gradually to the right the side reduce sectional area.
Because lifting head 342 is the sectional area of side minimizing to the right gradually, so form the circular shape with certain curvature.Such curvature is applicable to the left surface and its position that closely contacts of annulus through hole 320 too, i.e. the position that closely contact of the right flank of the left surface of annulus through hole 320 and lifting head 342 sectional area of the inner peripheral surface of side minimizing to the right gradually.
The sectional area of lifting head 342 is smaller relatively than the sectional area of drainpipe connecting portion 240, and condensed water is flowed in the outer peripheral face and the space between drainpipe connecting portion 240 inner peripheral surfaces of lifting head 342.
In addition, piston portion 344 begins body extension formation from the right flank of lifting head 342.Piston portion 344 roughly is vertical cylindrical shape, and the diameter of piston portion 344 is little than the minimum diameter of annulus through hole 320, so can connect the middle part of its annulus through hole 320.
Piston portion 344 has certain-length, is formed with the extension projection 346 of limited piston portion 344 left directions motion at the right-hand end of piston portion 344.Hang projection 346 from the tab-like one-tenth in the outside side of the outer peripheral face of piston portion 344.
Upside and downside (see figure 6) at piston portion 344 dispose extension projection 346 respectively, form a pair of.And the extension projection 346 of upside is to have certain thickness " " shape, and the extension projection 346 of downside has certain thickness " " shape.
Lift valve 340 moves after the certain-length when move the side left, hangs the right flank of the front contact annulus through hole 320 of projection 346, limited piston portion 344 further left the side move.
Therefore, hang the projection 346 more outstanding formation of inner peripheral surface radius than annulus through hole 320, the jag of hanging projection 346 is to the vertical range in the piston portion 344 axle center interior ring radius greater than annulus through hole 320.
Describe the effect of air-conditioner below in detail with the anti-locking apparatus that refluxes.
At first, if outside power turn-on, 160 fan electromotors that are connected of a side and axial-flow fan 170 that are configured in axial-flow fan 160 produce rotary power.The rotary power of fan electromotor 170 is delivered to axial-flow fan 160.Therefore, accept axial-flow fan 160 rotations of fan electromotor 170 rotary powers, according to the rotation of axial-flow fan 160, the air of the interior space is drawn into indoor set 100 inside.
The room air that enters because of axial-flow fan 160 rotation flow into indoor set 100 inside by the suction hole 122 of front grid 120.By suction hole 122 inhaled airs after filtration the foreign matter of larger particles, also filter out at the foreign matter of molecule when the air cleaner 130.
The air that filters the molecule foreign matter carries out heat exchange with the mobile refrigerant of heat exchanger 150 inside in by the process of heat exchanger 150.Through the air of over-heat-exchanger 150 heat exchanges under the turning effort of axial-flow fan 160 to the steam vent side flow.Adjusted by air exhaust blade 114 and air draft blinds 116 to the steam vent flow air and to discharge to the interior space again when discharging directions.Carry out said process repeatedly, change the air ambient of the interior space more comfortablely.
But, when the air of the interior space when in the process of over-heat-exchanger 150, carrying out heat exchange with the refrigerant of working fluid, the surface of heat exchanger 150 produces condensed water because of temperature difference.Condensed water flows along heat exchanger 150 surfaces that tilt, and gathers 260 li of drip trays at last.
In addition, if outside power turn-on, draining pump 200 also operates.During draining pump 200 runnings, draining tubule 220 inner move of the condensed water of 260 li gatherings of drain pan by being communicated with draining pump 200.Condensed water is discharged to the outside of indoor set 100 through drainpipe connecting portion 240 and scupper hose (not shown).
By the condensed water process hose transition 244 of drainpipe connecting portion 240, through the anti-locking apparatus 300 of the backflow of hose transition 244 inside.Anti-locking apparatus internal condensation water is mobile owing to reflux, and piston portion 344 moves along the flow direction of condensed water.
Piston portion 344 moves to the flow direction of condensed water, and lifting head 342 separates with the front end face of annulus through hole 320.Lifting head 342 separates with the front end face of annulus through hole 320, the slit occurs between the outer peripheral face of the inner peripheral surface of annulus through hole 320 and piston portion 344, and from then on condensed water flows in the slit.The condensed water that flows is moving from the rear end face forward end surface current of circular shape lifting head 342 with certain curvature.
The condensed water that flows by the anti-locking apparatus 300 that refluxes passes through tubule connecting portion 244 backs by condensation water hole 248.Condensed water by condensation water hole 248 is discharged to the place that will discharge through hose transition 242 and scupper hose (not shown).Scupper hose (not shown) is connected back formation elongation bending upward with hose transition 242.
If have a power failure or overcurrent causes open circuit and external action such as short circuit under the power supply of conducting be cut off, draining pump 200 runnings stop.The running of draining pump 200 stops, then the condensate return of scupper hose (not shown) internal flow that forms at bending elongation upward.
At this moment, the anti-locking apparatus 300 of backflow that is provided to tubule connecting portion 244 inside plays a role, and stops condensate return.
The effect that describes the anti-locking apparatus 300 that refluxes in detail is as follows.
The condensed water that begins to reflux from scupper hose (not shown) flows into the inside of tubule connecting portions 244 through hose transition 242 and condensation water hole 248.
The condensed water that flows into tubule connecting portion 244 inside side to the right promotes the front end face of lifting head 342, piston portion 344 just to the right the side move.Therefore, because piston portion 344 moves, lifting head 342 is close to the front end face of annulus through hole 320.
As mentioned above, if lifting head 342 is close to the front end face of annulus through hole 320, condensed water just can not flow again.Can prevent condensate return thus.
