In this water storage tank 52, accumulate about about 5L～6L (the washings amount is the occasion of 6kg) with primary drying.Make the capacity about part three times, then water storage tank 52 is about 15L.The available inner space of contrast housing cabinet 1 also is appropriate capacity.
It is dry to carry out several, when the water storage quantitative change of water storage tank 52 is full, flows through the overflow pipe 54, scupper hose 62 draining outside machine that connect water storage tank 52 and draining valve 22.
With washings 9 washings, rinsing, dehydration, behind dry the end, Xi Di occasion is used the condensate water that accumulates in the water storage tank 52 once more.Be given to water pump 53 in washing feedwater luck, outwards feed water in the bucket 2 from flexible hose 10 by the water conduit 55 of giving that is connected with washing agent input box 8.
The condensate water of accumulating can be used as washings or washings utilization.Like this, by in water storage tank 52, accumulating condensate water and utilizing, can realize the water saving of washings.
Then, quote Fig. 2 and illustrate in greater detail heat pump assembly.
As quote Fig. 1 explanation, heat pump assembly 70 is arranged on from supporting outside barrels 2 the center of gravity place near input port 11b, promptly the place ahead to the position.As with compressor 15 refrigerant compressed, use carbon orgon compound or carbon dioxide, but in recent years because environmental problem bans use of the carbon orgon compound, so mainly use carbon dioxide.
With compressor 15 refrigerant compressed, send to compressor 15 once more by radiating tube 58, adjustment valve 26, endothermic tube 59.
This is cold and hot to be delivered on the heat dump 57 effectively from endothermic tube 59, and the temperature around making reduces.The drying of the humidity that the upstream side circulation canal part 23a by circulation canal 23 sends here is utilized heat dump 57 condensing condensing with air.The condensate water of condensing utilizes condensation water drainage flexible pipe 27 to discharge in circulation canal 23.
This heat pump assembly, its part has been practical by air-conditioning etc., and the device of the heat that the cold-producing medium of applied compression takes place also is practical.
If compressor 15 is output as about 400W, then refrigerant compressed obtains about 3～6 times heat energy of the output of compressor 15.The drying of the high temperature that humidity is high utilizes Air Blast fan 24 to be transported to the heat dump 57 by circulation canal 23a with air from the flow export 69 at the rear portion of outer bucket 2.Here, dry moisture with air is cooled into to condensing water and is drawn, so drying becomes the drying air of the low low temperature of humidity with air.
Become the drying air of low humidity, with the drying air of radiator 56 heating becoming the once more low high temperature of humidity.The drying of this low humidity and high temperature flows through the downstream of circulation canal with air circulation canal part 23b flows into the dry bucket 11 of washing from inflow entrance 68, thereby carries out the drying of washings 9.
The moisture of absorption washings becomes the drying of high humidity with air backflow in the dry bucket 11 of washing, discharges from flow export 69 once more.
The further discharge of the condensing water of supplementary notes.
The inboard of heat dump 57, radiator 56 becomes the dry heat exchange stream that carries out heat exchange with circulation of air.Dry mobile from heat dump 57 to radiator 56 with air.At this moment, if along the rotary middle spindle that washs dry bucket 11 heat dump 57 relative radiators 56 being positioned at inboardly with radiator 56 heat dump 57 disposes, constitute the circulation canal 23 that the drying in the outer bucket is blown to the front side from the inboard with air, the radiator 56 that then is positioned at the heat dump 57 relative downstreams of upstream side in the stream of drying with air is configured in low position.
Therefore,, do not flow to a side of radiator 56 at the condensing water that heat dump 57 takes place, and from heat dump 57 under low side's spontaneous current, utilize the condensation water drainage flexible pipe 27 that is communicated with the position also lower from circulation canal 23 interior discharges than heat dump 57.
Because condensing water does not remain in the heat exchange stream,, carry out the drying of washings well so drying is not produced obstacle with flowing of air.
By making circulation in dry heat dump 57 with air heat pump assembly 70 of bucket 2 outside being installed on, radiator 56, circulation canal 23, Air Blast fan 24, the dry bucket 11 of washing like this, the washings 9 in the dry bucket 11 of washing is dried.

Also have in Fig. 5 (a),, therefore can not obtain as the above-mentioned effect of improving balance because compressor 15 is installed on the inboard part of outer bucket 2.So, shown in Fig. 6 (a), also compressor 15 can be located on the forward part of outer bucket 2.
Have, in Fig. 6 (a), dry suction inlet 68 with air end face 2a top of bucket 2 outside being formed at flows into cooling chamber 66 again.As Fig. 6 (b) and (c), the next door 71 of setting in cooling chamber 66 in from the center to periphery wall spaced chamber, the opposition side of next door 71 is provided with outlet 69 and gets final product.Drying flows out from cooling chamber 66 by outlet 69 with air, flows into circulation canal 23.By such formation cooling chamber 66, can be elongated at cooling chamber 66 inner dryings with the stream that air flows, can carry out heat exchange well.
The relative structure of Fig. 5 (a), shown in Fig. 6 (a), also can make make cooling chamber 66 the bottom not with outer bucket 2 in the structures that are communicated with, the osculum 72 of discharge condensate water is set in the bottom of cooling chamber 66.On osculum 72, also can connect condensate water with scupper hose 27, pipeline also can be set be connected with scupper hose 23.
Have again, as shown in Figure 7, also the refrigerant tubing 25 in relative compressor 15 downstreams promptly can be constituted the part of the refrigerant tubing 25 of radiator, introduce cooling chamber 66 promptly also is positioned at the downstream than heat dump 57 circulation canal 23.The introducing position of refrigerant tubing 25 be blown into dry mouthful 73 close the getting final product that are blown into air to the dry bucket 11 of washing.Therefore, blow-off outlet 73 is located at the input port 11a side of washing dry bucket 11, the front side (input oral-lateral) of bucket 2 got final product outside the introducing position in circulation canal 23 of refrigerant tubing 25 was located at least.At this moment, compressor 15 also can be configured in the front side of outer bucket 2 as shown in Figure 6.
As Fig. 5～shown in Figure 7, do not use cooling fan but constitute heat dumps 57, thereby can make the heat dump that is difficult to tangle broken the end of a thread by the crooked refrigerant tubing 25 of multilayer.Thus, might make the structure of omitting filter 63.
In addition, though the performance of the heat pump assembly 70 of the dry operating of washings slightly reduces relatively, also can utilize heat dump 57 coolings to be located at the motor 19 in the outside of cooling chamber 66.
In addition, about being located at the fan 24 in the circulation canal 23, also can constitute as Fig. 8.
In order to promote the drying of washings, need to increase dry air quantity with air.In order to increase air quantity, the diameter that needs to increase the rotation number of fan 24 or add big fan 24.But, if increase the then noise increase of rotation number of fan 24, then limiting configurable place if add the diameter of big fan 24, can not freely dispose.
So, constitute fan 24 with two fan 24a and 24b.Configuration fan 24a in the circulation canal 23 of the upstream side of heat dump 57 disposes fan 24b in the circulation canal 23 in the downstream of radiator 56.Have again, control this two fan 24a, 24b individually, carry out optimal control so that the control air quantity gets final product according to the running control of scrubbing-and-drying unit.
The humidity sensor (not shown) that detects the humidity in dry bucket 11 of washing or the outer bucket 2 for example is set, gets final product based on the running of the fan 24b of the fan 24a of humidity control heat dump 57 sides that detect and radiator 56 sides.
In the occasion of using two fan 24a and 24b,, can reduce to drain to the operating sound of outside fan 24 by any one party being configured in the rear side in the housing cabinet 1.Particularly that operating frequency or the duration of runs is a long side's the rear side of fan arrangement in housing cabinet 1 gets final product.
Kind as compressor has reciprocating manner, rotation mode and linear fashion.In any way can make.
But, because all sizes of heat pump assembly need compactness, compressor is made the linear fashion of using DC Brushless Motor with drive motor, this DC Brushless Motor is used the magnet with the terres rares of neodium magnet, can make noise, vibration is little and compressor excellent in efficiency is used motor thus.
As the cold-producing medium that in heat pump assembly 70, uses, consider HC system (hydrocarbon: iso-butane, butane, propane, cyclopropane etc.) or carbon dioxide etc.The cold-producing medium of HC system is flammable and is heavier than air, so electrical equipment, connector portion and control circuit preferably are configured in face.
Then quote the running operation that Figure 10 illustrates the scrubbing-and-drying unit of drum-type.
This running operation is to represent automatically to carry out the block diagram of the general automatic washing process of following operation, comprise: wash off attached to the dirt on the washings 9, with rinsing washing agent is partly rinsed again, the moisture that is contained in the washings 9 is dewatered from dewatering hole 14 usefulness centrifugal force by the rotation of the dry bucket 11 of washing, and these moisture are discharged.
At first, feed water 28 by the operation of water-suppling electromagnetic valve 6.
In washing 29, as if the required water of amount of supply washings in outer bucket 2 shown in Figure 1, then DC Brushless Motor 19 is rotated and washing drying bucket 11 is rotated.
The rotary speed of the dry bucket 11 of at this moment washing is per minute 40～50 right side of turning left, and is right rotation, the anticlockwise of carrying out at interval several minutes with the time-out, washings 9 is held together up, Yi Bian the washing of beating on one side with the dry bucket 11 interior lifters 16 of washing.
Washing 29 finishes, and transfers to the drainage procedure 30 that the washings that comprise dirt that flow out from washings 9 are discharged outside the machine of scrubbing-and-drying unit.
After draining finishes, transfer to the dehydration procedure 31 of sloughing the washing agent part that is contained in the washings 9.In dehydration procedure 31, high speed rotation washing drying bucket 11 dewaters by centrifugal force washings 9 from a plurality of dewatering holes 14 that are arranged at the inwall that washs dry bucket 11.
Dehydration procedure 31 finishes, and transfers to the rinsing process 33 that rinsing is contained in the washing agent part in the washings 9.
Before entering the running operation of rinsing process 33,29 is identical with supplying with required clear water in the feedwater operation 32 outside buckets 2 of supplying with clear water during with washing.
The identical feedwater carried out about about 30L when washing of the required clear water of general rinsing.
The clear water of supply ormal weight then automatically proceeds to rinsing process 33, and 29 identical making when washing dry barrel of 11 low speed and reverses are rotated during with washing, remove the washing agent part that is contained in the washings 9.
Draining-dehydration-rinsing (2)-draining and above-mentioned action after rinsing finishes are carried out in the same manner, transfer to the final dewatering operation 38 of fully sloughing the moisture that is contained in the washings 9 at last.
The dewatering time of final dewatering operation 38 generally is more than 5 minutes, makes the moisture that washs dry bucket 11 high speed rotations and remove washings 9, and dehydration rate at this moment reaches 60～65%.
In addition, heat pump assembly 70 is set on the scrubbing-and-drying unit of drum-type, carries out from the occasion of the scrubbing-and-drying unit of the drum-type of washing drying automatically etc., after final dewatering operation 38 finishes, transfer to drying process 39 automatically.
In drying process 39, after fully removing the moisture of washings 9 with dehydration procedure, utilize on one side the heat pump assembly 70 of other explanation of Fig. 2 to blow on the washings 9 with air, make the dry bucket 11 of washing turn left the speed counter-rotating right on one side or direction is rotated and the moisture of removing washings 9 makes its drying with per minute about 50 with the drying that radiator 56 carries out the warm wind of heat exchange.
When the washings 9 of dry humidity, become the state that high temperature wets more in the dry bucket 11 of washing, so be transported in the heat dump 57 with Air Blast fan 24 by circulation canal 23a, the drying that condensing here humidity is high condenses it with air, and condensate water is by 27 drainings of condensation water drainage flexible pipe.
The air of dehumidifying is transported in the radiator 56, sends in the dry bucket 11 of washing from the inflow entrance 68 that washs dry barrel input port 11a side by circulation canal 23b.
When carrying out drying process, while make the dry bucket 11 rotation agitator treating things of washing, the air by in the dry bucket of circulation canal 23 usefulness Air Blast fans 24 circulation cleanings utilizes heat pump assembly 70 to dehumidify, heat, thus dry washing material 9.
Behind dry the end, transfer to automatically and finish 40 end washing dry runs.
The circuit block diagram of then quoting Figure 11 illustrates the driving of the scrubbing-and-drying unit of drum-type.
Power supply 41 is connected with AC100V50/60Hz, at first connects power switch 42.
The power supply of energising is by the filter circuit 43 of cut off the electricity supply line interference or aerial wave interference, the rectification circuit 44 that is used as the driving power of DC Brushless Motor 19 is transformed to the dc source of high pressure from AC power, supplies with to the direct-flow inverter drive circuit 45 as the DC Brushless Motor drive circuit.
Direct-flow inverter drive circuit 45 is made of and the control of turning round the IGPT element circuitry, this IGPT element circuitry is passed through the control instruction of microcomputer 49, spends or 180 each phase coil supply power of spending to DC Brushless Motor U phase 46, V phase 47, W phase 48 with electric angle 120.
The rotation control of DC Brushless Motor 19, the rotation of the rotor (province's sketch map) by having a plurality of magnet, in will signal input microcomputer 49 from the Hall integrated circuit element 50 of the peripheral part that is fixedly set in DC Brushless Motor 19, control rotation number and adjust the rotary speed of the dry bucket 11 of washing.
In addition, required clear water is by the instruction of microcomputer 49 during attached to the rinsing of dirt on the washings 9 or washing agent part removing when washing, and the water-suppling electromagnetic valve 6 that is connected with drive circuit portion 51 is switched on and fed water.And when draining, carry out the open operation of drain solenoid valve 22, outside the machine of scrubbing-and-drying unit, discharge the water of making dirty.
Have again, when drying, carry out the compressor 15 of heat pump assembly 70, the running control that valve 26, Air Blast fan 24 are adjusted in decompression.
Figure 12 is the flow chart that is used for utilizing again the control software of condensing water.
Expression is condensing and condensate water that form temporarily is stored in the water storage tank 52 during with drying, utilizes the flow process of this storage water when washing or rinsing again.
So, select the washing process S100 of washing,, carry out beginning S101 by pushing beginning switch 42 shown in Figure 4.
At first, with the operation of feedwater S102, export to the electrical instruction of water pump ON (S103).By these instruction feed pump 53 entrys into service, make the condensate water in the water storage tank 52 pass through to inject detergent boxes 8 to water conduit 55.Then, supply with condensate water through flexible hose 10 outside buckets 2.
Make water-suppling electromagnetic valve 6 open workings with the electrical instruction of water-suppling electromagnetic valve ON (S104) just now, clear water by detergent box 8, outwards bucket 2 in is supplied with washing or rinsing required water from flexible hose 10 from the water hose 5 that is connected with the water channel hose.
The clear water of condensate water and water channel on the way outwards feeds water in the bucket 2 simultaneously, is shortened time being shortened that is used to wash so expend in the time of feedwater.
Judge whether pass through the stipulated time with S105,, then continue to feed pump 53 and water-suppling electromagnetic valve 6 energisings if in the elapsed time to the conduction time of feed pump or water-suppling electromagnetic valve.But, through the occasion of stipulated time, carry out energising OFF to feed pump 53 with feed pump S106.
Accumulate condensate water about about 15L at most to water storage tank 52.If the pumpage of feed pump 53 is approximately 11 (L/ branches), then the water of 15L was just finished in 1 minute 30 seconds.Do not have in water storage tank 52 under the state of condensate water, make feed pump 53 running work, then operating sound or electric weight increase, and do not have the effect of saving.And the state of the anhydrous dry run of feed pump 53 continuation maintenances, bearing seals etc. directly wear and tear.Therefore, observe T minute S105 of process and carry out the control that stops of feed pump 53.
Be used to wash or the water of rinsing is approximately 25～30L, only the condensate water with water storage tank 52 does not reach the regulation water yield, so in the occasion that does not arrive predetermined water level S107, transfer to water-suppling electromagnetic valve S104 from electromagnet water supply valve 6 supply clear water.
If arrive regulation water yield S107, then the instruction of output washing running S108 is washed or rinsing etc.Washing S108 finishes, and transfers to following operation S109.
The feedwater of washing or rinsing begins the clear water of condensate water and water pipe together like this, finishes the feedwater of condensate water early, and the feedwater of carrying out water pipe is up to the water yield that reaches regulation.In a word, the feedwater time of condensate water is short, and the feedwater time of water pipe is long.
Thus, shorten the feedwater time, can not utilize condensate water with at all not staying, can realize stipulating the washing of the water yield (the suitably water yield).
The method of operation of the occasion that stops dry operating on the way then, is described.
In scrubbing-and-drying unit, consider after the beginning dry operating, temporarily to stop to take out washings or confirm drying regime.In this occasion,, then begin dry operating again and rise (recovery) waste of generation time up to pressure if stopping compressor 15 reduces pressure.So, do not produce this waste of time shorten dry operating time that the user feels aspect important.
Running when utilizing Figure 13 and Figure 14 explanation temporarily stopping in drying way.Figure 13 is with in the rotary speed of the dry bucket 11 of the blocking utilization of enclosing cover 12 washing and the dry bucket 11 of washing or near the flow charts operated of the temperature the dry bucket 11 of washing.And Figure 14 is a flow chart of operating the dry bucket 11 of washing, compressor 15 and fan 24 when temporarily stopping.
At first, only open the thing of enclosing cover 12 a little times contact clothes, under the state of not locking enclosing cover 12, carry out dry operating as far as possible for the drying regime that in the way of drying, can accomplish to confirm washings simply etc.Therefore, the temperature that will be used for dry warm wind is made as below 80 ℃, is not blown into overheated warm wind.In this state, constantly carry out judging the locking of operation enclosing cover 12 when carrying out dry operating as the enclosing cover locking of Figure 13.
Judge after (S200) in the locking of beginning enclosing cover, measure the rotary speed (S201) of the dry bucket 11 of washing, in this speed is 100[r/min] below the occasion of (S202), instrumentation washs the temperature (S203) in the dry bucket 11 once more, occasion at (S204) below 70 ℃, make the lamp of expression enclosing cover locking turn off (S205), remove enclosing cover locking (S206).And, rotary speed at the dry bucket 11 of washing is 100[r/min] more than the occasion of (S202), or temperature is the occasion of (S204) more than 70 ℃ in the dry bucket 11 of washing, makes the lamp (S207) of expression enclosing cover locking light (or turning off), keeps enclosing cover locking (S208).After the locking of operation enclosing cover, finish the enclosing cover locking and judge (S209) like this.
