Draining pump from described drain pan by drainpipe draining,

Detect the water level in described drain pan water level detecting mechanism,

And the drainage control mechanism of the described draining pump that turns round in the time that setting discharge level is above in the sensed water level based on this water level detecting mechanism,

Described drainage control mechanism is configured to the situation more than described setting discharge level corresponding to described sensed water level and starts the running of described draining pump, thereafter, starts to set the timing of water discharge time in the time that described sensed water level becomes lower than described setting discharge level,

,, in the moment through this setting water discharge time, stop the running of described draining pump thereafter.

According to this formation, more than sensed water level becomes setting discharge level and after the running of beginning draining pump, in the time that sensed water level becomes lower than setting discharge level because of the running of this draining pump, the running that starts regulation draining pump stops the timing of the setting water discharge time in moment.

Therefore, under the more situation of the condensed water that flows into drain pan from flat heat transfer part, correspondingly, sensed water level becomes than setting that discharge level is low and to start to set pump duration of runs (can say, extend the duration of runs with respect to the pump of the essence of setting water discharge time) before the timing of water discharge time elongated.

And, correspondingly, start to the duration of runs that running stops also elongatedly from the running of draining pump, and the displacement of the each running of draining pump increases.

Thus, for example, set discharge level and start the running of draining pump when above and also start compared with the situation of the timing of setting water discharge time with becoming in sensed water level, under the more situation of the condensed water that flows into drain pan from flat heat transfer part, can effectively suppress the situation of the start and stop frequency gets higher of draining pump.

Therefore, can effectively alleviate the discomfort that makes the sound equipment that user produces because of the start and stop of draining pump.

In addition, the increase of the draining pump start and stop frequency under the inflow water yield situation how that effectively prevents condensed water like this, and on the contrary the condensed water that flows into drain pan from air cooling end than common few situation, correspondingly, sensed water level becomes than setting discharge level and shortens the pump duration of runs (pump of above-mentioned essence extends the duration of runs) low and that start to set before the timing of water discharge time.

And, correspondingly, starting also to shorten to the duration of runs that running stops from the running of draining pump, the displacement of the each running of draining pump reduces.

Thus, can effectively prevent under the less situation of the condensed water that flows into drain pan from flat heat transfer part, because of the duration of runs of draining pump long, before the running of draining pump stops, drain pan becomes empty, thereby cause the situation of the idle running (, there is no the pump running under the state of enough suction water) of draining pump.

Therefore, can effectively prevent discomfort, draining pump deteriorated in early days of the sound equipment of the idle running based on draining pump.

In addition, in order to change the duration of runs that makes draining pump corresponding to condensed water to the variation of the inflow water yield of drain pan, also consider after the running of draining pump starts, the water level detecting in drain pan drops to the state that starts water level than the low setting timing of setting discharge level, and start to set the timing of water discharge time in this detection moment, or the water level in detection drain pan is reduced to the state of setting draining stopping water level, and stop the running of draining pump in this detection moment.

But, in these occasions, whether the water level in drain pan the detection of setting more than discharge level, also needs water level in drain pan to be reduced to and sets the detection that timing starts water level or sets the state of draining stopping water level, and the test item number of water level increases.

On the other hand, if above-mentioned formation, only need water level in drain pan whether in the detection of setting more than discharge level, under the state of the hysteresis aspect the water level detecting in the time utilizing water level to rise and when water level reduces, also can make the water level that starts the water level of draining pump running and start the timing of setting water discharge time have difference.

Therefore, can reduce the test item number of water level, in the time for example using switch as water level detecting mechanism, a switch can only using by setting discharge level completes.

That is, the running of carrying out draining pump by timer control stops, and the device that can reduce the test item number of water level and be used in water level detecting forms simple.

Of the present invention the 24 feature form be,

Described setting water discharge time is to be reduced near the required time bottom of described drain pan from the water level of timing zero hour of described setting water discharge time at the water level of drain pan described in the running of described draining pump in design.

According to this formation, even if flow into the flow of the condensed water of drain pan changes a little from flat heat transfer part, also the variation that extends the duration of runs with the pump of the foregoing essence changing corresponding to this inflow water yield is interosculated, and (set water discharge time through the moment) water level of setting drain pan for that can under the high state of accuracy, the running of draining pump be stopped to the moment is reduced near moment drain pan bottom.

Therefore, can prevent the idle running of draining pump and more effectively reduce the start and stop frequency of draining pump.

Of the present invention the 25 feature form be,

Described drainage control mechanism is configured in the time that described sensed water level rises to than the high capping water level of described setting discharge level, stops described cooling operation.

According to this formation, even if the water level in drain pan is set discharge level and further risen because certain reason exceedes, also in the time that rising to capping water level, sensed water level stops cooling operation, to stop the generation of more condensed waters at flat heat transfer part place.

Therefore, can prevent more reliably the seepy question that causes the storage water of drain pan to overflow.

In addition, in the enforcement of this structure, also can be for example by different switches form the water level that detects in drain pan whether the water level in low level test section and the detection drain pan more than setting discharge level whether rise to the high position test section etc. of capping water level, detect independently of each other each water level.

Now, even if the water level in drain pan rises because low level exceedes setting discharge level by the fault of test section, thereafter, also can be by detect water level in drain pan and rise to the state of capping water level by the independent water level detecting of test section based on a high position, in this, can prevent more reliably the seepy question that the storage water of drain pan overflows.

Of the present invention the 26 feature form be,

Described drainage control mechanism is configured to corresponding to described sensed water level rises to the situation of described capping water level and stops after described cooling operation, starts to set the fulltime timing of guarantor in the time that described sensed water level becomes lower than described capping water level,

,, protecting the fulltime moment through this setting, stop the running of described draining pump thereafter.

According to this formation, rise to capping water level and stop after cooling operation in sensed water level, in the remaining in operation of draining pump, the moment that drops to capping water level from the water level drain pan, draining pump running is set and is saved from damage the time, and setting guarantor's fulltime process moment, draining pump stops.

Therefore, under the state that stops cooling operation, the situation of the draining pump that turns round necessarily can be avoided exceeding, and situation of the worry of seepy question can be avoided exceeding the running of necessary pump and bringing to user on the contrary because of this.

In addition, more than sensed water level becomes capping water level and stop after the running of air cooling end, because of remaining in operation of this draining pump, sensed water level becomes when lower than capping water level, and the running that starts regulation draining pump stops the setting in moment and protects fulltime timing.

Therefore, form identical with the 23 feature, after stopping, cooling operation also flows into the more situation of the residual condensed water of drain pan from flat heat transfer part, correspondingly, sensed water level becomes that to start to set the pump duration of runs (pump of essence extends the duration of runs) of protecting before fulltime timing elongated than capping water level is low.

In addition on the contrary, under the state that stops cooling operation, from the few situation of the residual condensed water of flat heat transfer part inflow drain pan, correspondingly, sensed water level becomes lower and start to set and shorten the pump duration of runs (pump of essence extends the duration of runs) of protecting before fulltime timing than capping water level.

Therefore, can be under the state that stops cooling operation, discharge from drain pan the residual condensed water that flows into drain pan from flat heat transfer part reliably, and exceed necessary draining pump running after effectively avoiding cooling operation to stop.

In addition, according to above-mentioned formation, form identical with the 23 feature, only need the whether detection more than capping water level of water level in drain pan, under the state of the hysteresis aspect the water level detecting in the time utilizing water level to rise and when water level reduces, can make the water level that stops cooling operation having difference with the water level that starts the fulltime timing of setting guarantor.

Therefore, can reduce the test item number of water level, in the time for example using switch as water level detecting mechanism, a switch can only using by capping water level completes.

Of the present invention the 27 feature form be,

It is that the water level of protecting fulltime timing zero hour from described setting at the water level of drain pan described in the running of described draining pump is reduced near the required time bottom of described drain pan in design that the time is saved in described setting from damage.

According to this formation, water level in drain pan rises to capping water level and stops after cooling operation, the residual condensed water that still remains in air cooling end also continues to flow into drain pan, on the other hand, set and save from damage the time by setting described above, can discharge the storage water that is present in drain pan from drain pan, be included in and set the total amount of protecting the residual condensed water also flowing into from the flat heat transfer part of running halted state after fulltime timing zero hour, and under the state roughly completing in this draining, draining pump is stopped.

Therefore, can prevent the idle running of draining pump, and can in order to prepare, next cooling operation starts, maintenance inspection before it and make drain pan become roughly empty state, thus, the security of seepy question when maintenance inspection can further improve next cooling operation time, before it.

And, in the enforcement of any in above-mentioned the 23～the 27 feature forms, also can adopt any in following cited structure.

Form the bag-shaped pipe arrangement portion of extending and then extending upward from the bottom discharge mouth of drain pan at drainpipe downwards, and between the position lower than the bottom of drain pan is by draining pump, put the bag-shaped pipe arrangement portion being arranged in drainpipe.

Drainage control mechanism is configured in sensed water level and rises to when setting the high capping water level of discharge level, stops cooling operation, and the running of again attempting draining pump starts operation.

Drainage control mechanism is configured to start to set the moment that the running of again attempting draining pump from rising to the situation of capping water level corresponding to sensed water level starts operation protects fulltime timing, the moment of saving time process from damage in this setting thereafter, is carried out the running shut-down operation of draining pump.

Setting is saved the running that the time sets in design by draining pump from damage and is discharged from drain pan the needed time of total amount that also flows into the residual condensed water of drain pan the situation that rises to capping water level corresponding to sensed water level stops cooling operation from flat heat transfer part.

The capacity of drain pan is set in design and can be stored in the capacity that stops also flowing into from flat heat transfer part after cooling operation the total amount of the residual condensed water of drain pan corresponding to sensed water level rises to the situation of described capping water level.

Drainage control mechanism is configured to that the running that is accompanied by draining pump starts and the timing that starts to set binding hours, thereafter, in the time that the running of draining pump lasts till the process moment of this setting binding hours, stop forcibly the running of draining pump in the process moment of this setting binding hours.

Of the present invention the 28 feature form be,

The body upper frame of the horizontal posture of the upper end that links described flat heat transfer part is set,

And the upper surface part at this body upper frame forms the guiding groove extending along left and right directions,

Arrange along this guiding groove and move up freely and can be by the fixing operation slide unit fixing with respect to described guiding groove at right and left,

Can be with respect to being positioned at the wall body at rear of described underpart shell and the overturning preventing member that links can carry out with the state of the movement of the direction to the left and right of the one of described slide unit under be installed on described slide unit.

According to this formation, by the slide unit movement of direction to the left and right, can select the suitable coupling position of overturning preventing member with respect to wall body.And, after selected suitable link position, fix with respect to guiding groove by slide unit and with the overturning preventing member of its link by fixing operation, and by link this overturning preventing member with respect to wall body, can pass through the overturning of the anti-locking apparatus of this overturning preventing member.

Therefore, can, under high state such as the correspondence of the condition that arranges with respect to wall body structure etc., carry out aptly the disposal that overturning prevents.

Detailed description of the invention

(the first embodiment)

Fig. 1 shows the indoor set 1 of the aircondition of natural convection.This indoor set 1 possesses the flat heat transfer part 2 of the vertical posture of exposing towards body front.This flat heat transfer part 2 is viewed as the rectangle of lengthwise from fore-and-aft direction.

In addition, indoor set 1 possess the horizontal posture that is arranged on top body upper frame 1A, be arranged on the underpart shell 1B of bottom and the body sidepiece frame 1C across the vertical posture of the pair of right and left of this body upper frame 1A and underpart shell 1B., flat heat transfer part 2 is surrounded by described body upper frame 1A, underpart shell 1B and pair of right and left body sidepiece frame 1C.

As shown in Figure 1 and Figure 2, flat heat transfer part 2 is equally spaced arranged and is formed along the left and right width of indoor set 1 with parallel posture for the heat transfer element 3 many of the vertical posture across body upper frame 1A and the underpart shell 1B of portion (in this example for example 7) being inhaled to heat release and used.

, flat heat transfer part 2 comprise vertical posture heat transfer element 3 be arranged side by side group.

As shown in Fig. 6, Fig. 9, the total length that makes the straight sections 4a of heat-transfer pipe 4 spread all over heat transfer element 3 connects each heat transfer element 3 Zong center axial regions.

Heat transfer element 3 and heat-transfer pipe 4 form by good heat conducting material.In this example, heat transfer element 3 is aluminum.In heat-transfer pipe 4, use copper pipe.

As shown in Fig. 7, Fig. 9, connect upside protuberance in the straight sections 4a of heat-transfer pipe 4 of each heat transfer element 3 in abutting connection with to connecting by upside bend pipe 4b every a pair of.In addition, connect downside protuberance in the straight sections 4a of heat-transfer pipe 4 of each heat transfer element 3 in abutting connection with to every being a pair ofly connected by downside bend pipe 4c of replacing with upside.

, heat-transfer pipe 4 is to be connected in series by upper and lower bend pipe 4b, 4c the lobster back that multiple straight sections 4a form.

One end of this complications heat-transfer pipe 4 is connected with the off-premises station arranging outside room (omitting diagram) via covering the liquid side cross-over connection refrigerant pipe 5a of heat-barrier material, and the other end of tortuous heat-transfer pipe 4 is connected with this off-premises station via similarly covering the gas side cross-over connection refrigerant pipe 5b of heat-barrier material.

The off-premises station arranging outside room possesses compressor, outdoor heat converter, expansion valve and four-way valve.

That is, in cooling operation, make outdoor heat converter bring into play function as condenser, and make the tortuous heat-transfer pipe 4 of indoor set 1 as evaporimeter performance function, refrigerant R is circulated between off-premises station and indoor set 1 by two cross-over connection refrigerant pipe 5a, 5b.

; heating in running; switch refrigerant path by four-way valve; and make on the contrary outdoor heat converter bring into play function as evaporimeter; and so that the tortuous heat-transfer pipe 4 of indoor set 1, as the mode of condenser performance function, makes refrigerant R circulate between off-premises station and indoor set 1 by two cross-over connection refrigerant pipe 5a, 5b.

That is, in cooling operation, the capturing of the heat of gasification that the evaporation of the refrigerant R of the inside by the tortuous heat-transfer pipe 4 as evaporimeter performance function is followed, Cooling Heat Transfer pipe 4 and the heat transfer element 3 near heat-transfer pipe 4.Cooling by this, make flat heat transfer part 2 produce heat-absorbing action, cooling surrounding air.

At flat heat transfer part 2 places, cooling air (cold air) declines along the flat heat transfer part 2 of vertical posture naturally because of the difference in specific gravity based on temperature difference.This decline cold air is that indoor set arranges chamber and tiltedly direction to flow out towards front from the bottom of flat heat transfer part 2 to air-conditioning subject area.

Thus, following this cold airflow to go out to make to arrange under the form of large convection current that produces room air in chamber at indoor set, freezing, this is indoor.

Heating in running, the emitting of the condensation heat that the condensation of the refrigerant R by tortuous heat-transfer pipe 4 inside as condenser performance function is followed, heating heat-transfer pipe 4 and the heat transfer element 3 near heat-transfer pipe 4.By this heating, make flat heat transfer part 2 produce exothermic effects, and produce heat radiation from the surface of flat heat transfer part 2, and circumference air.

Naturally rise along the flat heat transfer part 2 of vertical posture because of the difference in specific gravity based on temperature difference at the air (heating installation) of flat heat transfer part 2 places heating.This rising heating installation arranges chamber towards front oblique upper to outflow from the top of flat heat transfer part 2 to indoor set.

Thus, following this current of warm air to go out to make to arrange under the form of the large convection current that produces room air in chamber (with cooling operation time rightabout convection current) at indoor set, heating with above-mentioned heat radiation is collaborative that this is indoor.

And, in this example, as shown in Figure 9, the cross-over connection refrigerant pipe 5a of liquid side is connected in to one end of the tortuous heat-transfer pipe 4 of the bottom of left and right one side that is positioned at flat heat transfer part 2.In addition, the cross-over connection refrigerant pipe 5b of gas side is connected in to the other end of the tortuous heat-transfer pipe 4 on the top of the left and right opposite side that is positioned at flat heat transfer part 2.

As shown in Figure 6, be integrally formed in front surface side and the rear surface side of each heat transfer element 3 the multiple tab portion 3a, the 3b that spread all over the total length of heat transfer element 3 and extend longitudinally.

Particularly, as shown, at each heat transfer element 3, in its viewgraph of cross-section, form the base portion 3A extending along left and right directions forming towards the baseplate part 3d of outside, left and right extension by the core 3c of column with from this core 3c in the enlarged drawing part of Fig. 6.

And, with the setting of equally spaced arranging along left and right under parallel posture, multiple front surface side tab portion 3a are forwards extended from core base portion 3A (3c, 3d).

Similarly, make locate accordingly and rearward extend from base portion 3A (3c, 3d) with rear surface side tab portion 3b and the front surface side tab portion 3a of the same quantity of front surface side tab portion 3a with the setting of equally spaced arranging along left and right under parallel posture.

Form the pipe inserting hole 3e that heat-transfer pipe 4 is connected at core 3c.The 3b ' of central flap portion of the rear surface side of extending from core 3c the 3a ' of central flap portion of front surface side extending from core 3c in front surface side tab portion 3a and rear surface side tab portion 3b, the front and back middle part that is formed on them divides and arranges and for the fixing securing member inserting hole 3f of element.

,, by making multiple tab portion 3a, the 3b of these vertical postures be located at each heat transfer element 3, guarantee significantly heat transfer area and heat radiation area with respect to the surrounding air of heat transfer element 3.

In addition, in cooling operation, make decline naturally swimmingly by pod portion each other of tab portion 3a, 3b of heat transfer element 3 cooling-air around, and accompany therewith, uncooled room air is induced to around heat transfer element 3 swimmingly.

In addition, make naturally to flow down swimmingly along the surface of heat transfer element 3 at the condensed water of the surface of heat transfer element 3 generation.

Thus, make, compared with the heat exchanger effectiveness between surface and the surrounding air of highland maintenance heat transfer element 3, therefore effectively and stably to produce the indoor cross-ventilation that flows out and accompany therewith from the cold air of flat heat transfer part 2 bottoms.

Similarly, heating in running, make heat transfer element 3 adding hot-air by pod portion each other of tab portion 3a, 3b and naturally rising swimmingly with the state that is accompanied by so-called chimney effect around, and accompany therewith, the room air of not heating is induced to heat transfer element 3 around swimmingly.

Thus, make compared with the efficiency of the heat exchange between surface and the surrounding air of highland maintenance heat transfer element 3, and therefore effectively and stably produce the indoor cross-ventilation that flows out and accompany therewith from the heating installation on flat heat transfer part 2 tops.

As shown in Fig. 2, Fig. 6, the rear surface portion of flat heat transfer part 2 and the side surface part of left and right are inaccessible plate 6 obturations of " C " word shape by the section shape of overlooking direction of the side board 6B that possesses rear surface board 6A and left and right.

In addition, in this obturation plate 6, the boudary portion of the side board 6B of rear surface board 6A and left and right is the bowing face in inner side with center from overlooking direction observation.

This obturation plate 6 is the two-layer structures (example of multiple layer structure) with good heat conducting material layer 6a and insulation material layer 6b.

; formed by the sheet material 6a (being aluminium sheet in this example) of the good thermal conductivity with glassy surface with the rear surface portion of flat heat transfer part 2 and the inner surface side (in the board 6A of rear surface, being equivalent to front surface side) of side surface part inaccessible plate 6 in opposite directions.In addition, being formed by heat-barrier material 6b (in this example, being foamed styrene) with its outer surface side (being equivalent to rear surface side in the board 6A of rear surface) that is the inaccessible plate 6 of opposition side.

That is, in cooling operation, be accompanied by the cooling of heat transfer element 3, the locular wall K of indoor set rear side is cooled, thereby likely produces condensation on the surface of this locular wall K.In addition, heating in running, be accompanied by the heating of heat transfer element 3, the locular wall K of indoor set rear side is heated, thereby likely produces and burn (painted) on the surface of this locular wall K.

On the other hand, by making inaccessible plate 6 become two-layer structure as above, in cooling operation, heat insulation to the cold and hot conduction of plate face direction diffusion and the insulation material layer 6b based on outer surface side of isolated, good heat conducting material layer 6a based on inner surface side by the cold air based on inaccessible plate 6, prevents the condensation generation at locular wall K place reliably.

In addition, in the time heating running, heat insulation to the warm conduction of plate face direction diffusion and the insulation material layer 6b based on outer surface side of isolated, good heat conducting material layer 6a based on inner surface side by the heating installation based on inaccessible plate 6, prevents the generation of burning at locular wall K place reliably.

And, in cooling operation, by the cold and hot conduction to the diffusion of plate face direction of the good heat conducting material layer 6a based on inner surface side, the inner surface side that makes inaccessible plate 6 low temperature equably in plate face direction, thus make the air at flat heat transfer part 2 places cooling on the width of left and right more homogenising and more efficient activity.Therefore, further promote to flow out from the cold air of flat heat transfer part 2 bottoms, and also improve this cold air and flow out the uniformity on the width of left and right.

And, in cooling operation, by the cold and hot conduction to the diffusion of plate face direction based on good heat conducting material layer 6a as mentioned above, avoid the topical hypothermia in the front surface side of inaccessible plate 6.Thus, the condensation that also prevents from therefore planting the inaccessible plate 6 front surface sides that topical hypothermia causes occurs.

Similarly, heating in running, by the warm conduction to the diffusion of plate face direction of the good heat conducting material layer 6a based on inner surface side, the inner surface side that makes inaccessible plate 6 high temperature equably in its plate face direction, thus make air heat more homogenising and more efficient activity on the width of left and right at flat heat transfer part 2 places.Thus, further promote to flow out from the heating installation on flat heat transfer part 2 tops, and also improve this heating installation and flow out the uniformity on the width of left and right.

And, heating in running, from the heat radiation on heat transfer element 3 surfaces towards rear and the heat radiation of side reflected by the glassy surface of the inner surface side of inaccessible plate 6, thus, further promote from flat heat transfer part 2 to indoor heat radiation, and also improve this thermal-radiating uniformity.

As shown in Figure 6, in the tab portion 3a of the front surface side in each heat transfer element 3, near the tab portion that is positioned at left and right directions center side, development length is forwards larger.

In other words the top that, connects these front surface side tab portion 3a each other become the curve towards outstanding tip shape or the semi arch in front from overlooking imaginary envelope that direction observes.Thus, the outflow cold air during to cooling operation, outflow heating installation and the heat radiation heating while running have given to the expansion of indoor set left and right width.

On the other hand, the rearward development length of the tab portion 3b of the rear surface side in each heat transfer element 3 equates (or roughly equal).

In other words the top that, connects these rear surfaces side tab portion 3b each other become straight line from overlooking the imaginary envelope that direction observes.Thus, interosculate with the uniform cold and hot conduction of diffusion as above or the warm conduction of the inner surface side good heat conducting material layer 6a based on inaccessible plate 6, make the low temperature of inner surface side (particularly, the front surface side in rear surface board 6A) of the cooling of heat transfer element 3 or the inaccessible plate 6 followed of heating or high temperature homogenising more in face direction.

Heat transfer element 3 is made by extrinsion pressing.And by this extrinsion pressing, each in tab portion 3a, 3b, core 3c, baseplate part 3d, pipe inserting hole 3e and securing member inserting hole 3f and heat transfer element 3 are side by side integrally formed.

In the time of this extrusion modling, the rear surface side tab portion 3b that development length is equal become to downward-extension posture arrange.And, the top group of these rear surfaces side tab portion 3b is connect to gear is transporting on instrument and the state of guiding under, carry out extrusion modling.

Thus, irrelevant with the complicated shape of cross section of heat transfer element 3, can under the state that the heat transfer element of forming process 3 is held in to firm position after dismount, carry out extrusion modling.In addition, avoid the moulding of the heat transfer element 3 causing because of the lodging in forming process bad.

, make by these pipe arrangements insert with otch 31a guide to the cross-over connection refrigerant pipe 5a on top and these three pipes of cross-over connection refrigerant pipe 5b that drainpipe 19 is connected with the other end of tortuous heat-transfer pipe 4 with the top at flat heat transfer part 2 under the state that they are collected from body upper box 1A to machine extension.Thus, can utilize the pipe arrangement through hole on the locular wall top using in general wall-hanging air conditioner, make above-mentioned three pipe 5a, 5b, 19 extend to outdoor.

And, in the case of the pipe arrangement use through hole that can guarantee locular wall bottom, also can make above-mentioned three pipe 5a, 5b, 19 extend to outdoor with through hole by the pipe arrangement of this locular wall bottom.

As shown in Fig. 3, Fig. 5, becoming the inner surface of upper end of back panel 7 of rear surface panel of body upper frame 1A, the heat-barrier material 6c that is sticked under assembled state and is connected with the insulation material layer 6b of the rear surface side of inaccessible plate 6.

In body upper frame 1A, as shown in Figure 1, be built-in with front running lamp to being located at front surface panel 10, abnormal lamp and carry out switch lamp operation and carry out the controller 33 of the processing etc. of the remote control transmitted signal being received by the acceptance division of being located at front surface panel 10.

As shown in Fig. 4, Figure 20, at drain pan 18, be provided with the filter screen 34 of the foreign matters such as dust in the draining that trapping discharges to drainpipe 19 in the drain outlet portion (, the connection oral area of drainpipe 19) of the dark bottom of drain pan 18a.

In addition, at drain pan 18, as the water level detecting mechanism of detecting the water level in drain pan 18, the first and second switch 35a, the 35b that carry out make-break operation are arranged on respectively to dark bottom 18a and near the bottom thereof of drain pan 18 according to the variation of the water level in drain pan 18.

As drainage control mechanism, the on-off action of above-mentioned controller 33 based on these switches 35a, 35b carries out the draining control of start and stop draining pump 20 etc.

About this draining control, particularly (with reference to Figure 20, Figure 21), the water level of the first switch 35a in drain pan 18 becomes to be set discharge level L1 and carries out ON Action when above.In addition, when the water level of the first switch 35a in drain pan 18 becomes lower than setting discharge level L1, disconnect action.

Similarly, the water level of the second switch 35a in drain pan 18 becomes capping water level L2 and carries out ON Action when above.In addition, when the water level of the second switch 35b in drain pan 18 becomes lower than capping water level L2, disconnect action.

In the start and stop of the draining pump 20 of the on-off action with based on the first switch 35a and discharge aptly under the situation of the storage water in drain pan 18, it is higher than setting discharge level L1 to make above-mentioned capping water level L2, so that the second switch 35b does not carry out ON Action.

Particularly, the on-off action of controller 33 based on switch 35a, 35b and carry out as follows control action (with reference to Figure 20～Figure 22).

If the water level in drain pan 18 rises to setting discharge level L1 and the first switch 35a carries out ON Action, controller 33 starts the running of draining pump 20.Thus, start the draining from drain pan 18.

If because this draining starts, the water level in drain pan 18 declines to such an extent that disconnect action than setting low and the first switch 35a of discharge level L1, and controller 33 starts to set the timing of water discharge time T1.And, in this timing, if from the disconnection action moment of the first switch 35a through setting water discharge time T1, controller 33 stops the running of draining pump 20.Thus, stop from the draining of drain pan 18.

; in the time of cooling operation, condensed water continuously flows into drain pan 18; on the other hand; as mentioned above; the intermittent running of the draining pump 20 by the on-off action based on the first switch 35a, keeps lowlyer than the capping water level L2 of break-make water level that is the second switch 35b by the water level in drain pan 18.

On the other hand, if the water level in drain pan 18 is set discharge level L1 and rises to capping water level L2 because certain reason exceedes, therefore the second switch 35b carries out ON Action, controller 33 is under the state of running that continues the draining pump 20 being caused by the ON Action of the first previous switch 35a, stop the running of compressor to stop the circulation (, stopping cooling operation) of refrigerant R.Thus, stop at the new generation condensed water at flat heat transfer part 2 places.

Afterwards, if the running of the draining pump 20 by under this cooling operation halted state, the water level in drain pan 18 declines to such an extent that than capping water level L2, low and the second switch 35b disconnects action, and controller 33 starts the timing that time T 2 is saved in setting from damage.And in this timing, if save time T 2 from damage through setting from the disconnection action moment of the second switch 35b, controller 33 stops the running of the draining pump 20 from the water level in drain pan 18 rises to while setting discharge level L1.

That is, by the running that time T 2 is saved in this setting from damage that runs through of draining pump 20, discharge reliably the mass storage water in drain pan 18, and avoid the necessary running that exceedes of draining pump 20 under the state that stops cooling operation.

In addition, the start stop operation of the draining pump 20 of the on-off action of controller 33 as mentioned above and based on first, second switch 35a, 35b is parallel, starts to set the timing of binding hours T3 in the time that the running of each draining pump 20 starts.And, in the timing of this setting binding hours T3, in the time that the running of draining pump 20 continues to the moment of setting binding hours T3 process, as extremely, in the running that stops forcibly draining pump 20 from running zero hour of draining pump 20 through setting the moment of binding hours T3.

And, make this setting binding hours T3 for saving from damage the long considerable times of time T 2 than described setting water discharge time T1, setting.

Save time T 2 from damage as setting, be set as the following time at device design aspect: also comprise that the disconnection action of the second switch 35b flows into the draining of the residual condensed water of drain pan 18 later, from the water level in drain pan 18 because of the draining of the running based on draining pump 20 from the water level of setting timing zero hour of saving time T 2 from damage (, the disconnection action water level of the second switch 35b) be reduced near drain outlet portion (, the bottom surface of the dark bottom of drain pan 18a) required time of drain pan 18.

In addition, in this example, as setting water discharge time T1, be set as the following time at device design aspect: the water level in drain pan 18 is reduced near drain outlet portion (bottom surface of the dark bottom of drain pan 18a) required time of drain pan 18 in the same manner because of the draining of the running based on draining pump 20 from the water level in the disconnection action moment of the first switch 35a.

And in addition, the capacity of drain pan 18 is set as following capacity at device design aspect: the capacity that the total amount (comprising the Already in water yield of drain pan 18 of ON Action moment of the second switch 35b) that also flows into the residual condensed water of drain pan 18 after the stopping of the compressor being caused by the ON Action of the second switch 35b can be received and stores.Thus, even be the defect of draining pump 20 own in the reason of impeded drainage, also can avoid reliably storing the seepy question that water overflows from drain pan 18.

In draining pump 20, use the pump that possesses return valve function.Thus, prevent the adverse current of draining from drainpipe 19 towards drain pan 18.

In addition.As shown in figure 10, in drainpipe 19, form the bag-shaped pipe arrangement 19a of portion that extends and then extend upward from the drain outlet portion of drain pan 18 downwards.And draining pump 20 is put between than the low position of the dark bottom 18a of drain pan 18 and is installed on this bag-shaped pipe arrangement 19a of portion (, becoming the pipe arrangement part of ponding state).

; arrange by this pump; and interosculate with the situation of setting as described above water discharge time T1, prevent from becoming that abnormal sound produces or the idle running of the draining pump 20 of the generation reason that pump is bad etc. (, in the pump running sucking under the state that water enough do not exist).

And, in this example, although the example that flat heat transfer part 2 is only exposed with respect to the front of indoor set 1 is shown, also can, omitting under the form of inaccessible plate 6, flat heat transfer part 2 be exposed with respect to front and the rear both sides of indoor set 1.Now, can implement the cooling and warming based on the cold air from flat heat transfer part 2 flows out, heating installation flows out to the front room area of indoor set 1 and rear room area simultaneously.

As shown in figure 33, also can be configured to the multiple guiding wing 35 (inflow direction changes an example of mechanism) that freely alter one's posture by the axle center rotation around along left and right width at least above-below direction pars intermedia setting of described rear surface board 6, and can operate to change the inflow direction of air IA to element resettlement section 2 by the posture changing of this guiding wing 35.

Thus, can make the inflow direction of the air IA from from air inflow portion 47 to flat heat transfer part 2 become according to the optimum orientation of the operational situation of indoor set 1 (heating running, cooling operation, running output), indoor conditions etc.

For example, as shown in Figure 33 (a), in the time heating running, by the posture changing of guiding wing 55, make the inflow direction of air IA obliquely upward, thereby can in running, under the little state of induced drag, make air IA flow into swimmingly to promote to flow out from flat heat transfer part 2 tops to indoor heating installation heating.

In addition, in the time of cooling operation, by the posture changing of guiding wing 55, make the inflow direction of air IA oliquely downward, thereby also can in cooling operation, under the little state of induced drag, make air IA flow into swimmingly to promote the bottom from flat heat transfer part 2 to flow out to indoor cold air.

And, for example as shown in figure 34, also can arrange and open and close the shutter door 56 (example of inflow entrance switching mechanism, an example of aperture area guiding mechanism) of adjusting freely, shutter door 56 opens and closes air inflow portion 47.

Thus, by the switching of shutter door 56, can make from the 47 induced air IA of air inflow portion to the use form of flat heat transfer part 2, the use form from the 47 induced air IA of air inflow portion to flat heat transfer part 2 does not become according to the best of the operational situation of indoor set 1 (heating running, cooling operation, running output), indoor conditions etc. and uses form.

In addition, by the aperture adjustment of shutter door 56, the air capacity that flows into flat heat transfer part 2 can be set as according to the optimum air amount of the operational situation of indoor set 1 (heating running, cooling operation, running output), indoor conditions etc. from air stream portion 47.

For example, as shown in Figure 34 (a), in the time heating running, make shutter door 56 become full-gear, and by the inducing action of the air-flow DA when heating, make air IA flow into flat heat transfer part 2 from air inflow portion 47, to promote from the top of flat heat transfer part 2 to indoor heating installation outflow.

On the other hand, can also adopt in the time of cooling operation, make shutter door 56 for off status or portion's separated position, the use form that makes cold air flow out to save from flat heat transfer part 2 bottoms etc.

In the above-described 2nd embodiment, although show the situation that air inflow portion 47 is made up of the gap forming between multiple boards 48,49, for example, also can form by being formed through in peristome of a plate etc.
