Next, with Fig. 2 and Fig. 3 the formation of foam detecting unit 58 is described.Foam detecting unit 58 by the common electrode 60 that is arranged on the tube 32 preceding bottoms that are filled with water, be arranged on the 1st electrode 62 near the warm braw air-supply passage 61 the air outlet 70 and the 2nd electrodes 64 that are located near the exhaust outlet 71 the Dehumidifying element 63 constitute.This foam detecting unit 58 is connected with resistance value decision circuitry 59, and resistance value decision circuitry 59 calculates the 1st resistance value between common electrode 60 and the 1st electrode 62 and the 2nd resistance value between common electrode 60 and the 2nd electrode 64.Adhere to separately under the frothy situation on the 1st electrode 62 and the 2nd electrode 64, the 1st resistance value and the 2nd resistance value are 100k Ω～500k Ω; Under the situation of not adhering to any foam, then be more than the 1k Ω.Therefore, according to detected resistance value, whether foam detecting device 58 can detect on the 1st electrode and the 2nd electrode electrode separately has foam to adhere to.
The height relationships of the installation site of the 1st electrode 62 and the 2nd electrode 64 is that the 1st electrode 62 is located on the position lower for the 2nd electrode 64.In addition, the 1st electrode 62 and the 2nd electrode 64 all are positioned at the below of heater 65 and Air Blast fan 66.
With Fig. 1 and Fig. 3 the operational circumstances in the above-mentioned formation is described below.During laundry, at first open lid 38, in swing roller 30, drop into washings, and in washing powder box 48, drop into the washing agent of ormal weight, make washing machine begin operation then.After the operation beginning, what at first carry out is washing process.In washing process, washings are injected in feed water valve 47 work, and washings process washing powder box 48 and water channel 49 and washing agent flow in the tube 32 that is filled with water together.Meanwhile, swing roller 30 begins rotation with the 1st desired speed (for example 120 rev/mins).
Under the effect of this operation, the washings that contain washing agent are stirred, and washing agent is dissolved in the washings gradually, and meanwhile, washings also bump with the sidewall of rhone 43.Such collision contains generation the washing foam of the detergent ingredients of high concentration, and these washing foams are full of the swing roller 30 and the tube that is filled with water between 32 gradually.After being full of, washing foam and just overflow, pick and place mouth 40 from the cylinder clothing and enter into swing roller 30 inside, contaminate on the washings wherein to the place ahead of the swing roller 30 and the tube 32 that is filled with water.
Afterwards, the centrifugal force that produces when relying on swing roller 30 rotations, the washing foam can enter into attached in the dirt on the washings, and dirt peeled off from washings, and then pass limbers 31 on the periphery wall of swing roller 30, come swing roller 30 and the space between the tube 32 of being filled with water in.By carrying out such operation repeatedly, can make washings obtain cleaning.Be filled with water water levels in the tube 32 of operating in like this will be implemented official hour before rising to the water level of regulation, afterwards, the rotating speed of swing roller 30 changes to the 2nd predetermined rotary speed (for example 40 rev/mins), the washing of just changeing repeatedly, stop, reversing, stopping action in official hour.
In addition, by making swing roller 30 with the 2nd predetermined rotary speed rotation, being contained in the lobe plate 35 that washings in the swing roller 30 are arranged on the swing roller 30 internal perisporium faces takes up along direction of rotation, fall from the certain height position again, stirred action repeatedly, therefore can play the effect of beating for washings, thereby washings is cleaned.
Above-mentioned washing operation will carry out official hour, if the washing foam takes place in a large number therebetween, the washing foam that generates can enter in the Dehumidifying element 63 from exhaust outlet 71, also enters in the warm braw air-supply passage 61 from air outlet 70 simultaneously.At this moment, adhere to the washing foam in the 1st electrode 62 of foam detecting device 58 and the 2nd electrode 64 on relatively low the 1st electrode 62 in position earlier, resistance value decision circuitry 59 reduces by the resistance value that detects between the 1st electrode 62 and the common electrode 60, it is superfluous to detect the washing foam, carry out the 1st simultaneously and eliminate the foam operation, as eliminate the washing foam of excessive generation by the rotation dwell time that prolongs swing roller 30.
In addition, even carried out the 1st above-mentioned elimination foam operation, the washing foam can not be eliminated, the washing foam also produces under superfluous (putting to such an extent that wait too much as washing agent) situation a large amount of, next, the washing foam that enters in the Dehumidifying element 63 from exhaust outlet 71 will arrive 2nd electrode 64 higher with respect to the 1st electrode 62 positions.At this moment, the surplus that can detect the washing foam by foam detecting device 58 is also in further increase, and the 2nd foam that therefore is used to eliminate the surplus washing foam of further increase is eliminated operation.This 2nd foam is eliminated operation, makes feed water valve 47 work, adds water in the tube 32 that is filled with water, and makes draining valve work simultaneously, and washings are discharged.Like this, the water that superfluous washing foam can be injected into pushes away, is discharged to the outside again.Through behind the official hour, make draining valve 46 shut-down operations, only make feed water valve 47 actions, water is added to predetermined water level.Like this, detergent concentration will obtain dilution in the washings, thereby can prevent to produce afterwards the situation of washing foam surplus again.
Like this, because the washing foam invades upstream side (Dehumidifying element 63) that inside is provided with the air-supply heat tunnel 67 of heater 65 and Air Blast fan 66 and the situation of downstream (warm braw air-supply passage 61) can detect respectively, difference according to the formation of the generation situation of surplus washing foam and dry circulation canal etc., even have only a side that the intrusion of washing foam has taken place in the upstream side (Dehumidifying element 63) of air-supply heat tunnel 67 and downstream (the warm braw air-supply passage 61), also can detect the production of superfluous washing foam reliably, adhere to and be impregnated on the heater 65 and Air Blast fan 66 in the air-supply heat tunnel 67 thereby can prevent to wash foam reliably.
In addition, when the 1st electrode 62 and the 2nd electrode 64 all are arranged on the upstream side (Dehumidifying element 63) of air-supply heat tunnel 67 and the side in downstream (warm braw air-supply passage 61), even the height of the installation site of these two electrodes is arranged to difference, but owing to be in same passage, after the advancing of washing foam can occur the 1st electrode 62 when very fast and detect the washing foam very much, the 2nd electrode 64 also detects the situation of washing foam at once, be created in and carry out the problem that the 2nd foam is eliminated operation immediately after the 1st foam is eliminated operation.And in the present invention, because the 1st electrode 62 and the 2nd electrode 64 are located at upstream side (Dehumidifying element 63) and downstream (the warm braw air-supply passage 61) of air-supply heat tunnel 67 respectively, therefore can prevent the above-described problem from occurring.
In addition, when carrying out the 1st foam elimination action and the 2nd foam elimination action, by heater 65 and Air Blast fan 66 are moved simultaneously, perhaps make Air Blast fan 66 single movements, also can be in the tube 32 that is filled with water, dispelling attached to the washing foam on the 1st electrode 62 and the 2nd electrode 64.
Such washing action is being carried out behind the preset time, and washing process promptly comes to an end, and carries out the 1st drainage procedure.In the 1st drainage procedure, draining is carried out in draining valve 46 work (opening).At this moment, the washings of tube in 32 that are filled with water are discharged to machine exterior through water discharge outlet 44, drainage channel 45 and draining valves 46.Afterwards, change the 1st dehydration over to.
In the 1st dehydration, swing roller 30 is accelerated to the 3rd predetermined rotary speed (as 900 rev/mins), and with the 3rd predetermined rotary speed rotation preset time, makes the contained washings of washings dehydrated.At this moment, owing in washing process, utilize foam detecting unit 58 to carry out reliable detection for the foam surplus, when producing the foam surplus, carried out the operation of eliminating the washing foam, therefore can prevent because of washing the dehydration starting defective mode that foam causes, dewater swimmingly, thereby can reach the rinsing performance and the dewatering of regulation.
After the 1st above-mentioned dehydration had been carried out preset time, feed water valve 47 actions added washings through washing powder box 48 and water channel 49 in the tube 32 that is filled with water, carry out the 1st rinse cycle.In the 1st rinse cycle, the speed setting of swing roller 30 is the 2nd rotary speed (as 40 rev/mins), and carry out the action just change, stop, reversing, stop repeatedly, in official hour, carry out making washings be arranged on swing roller 30 in the lobe plate on the peripheral wall surface 35 to take up, arrive the rinsing that falls behind the certain height position along direction of rotation and move repeatedly.
Then, carry out 2nd drainage procedure the same, after the 2nd dehydration, carry out 2nd rinse cycle the same again with the 1st rinse cycle with the 1st drainage procedure.Follow again, carry out 3rd drainage procedure the same, the final dewatering process the same with the 1st dehydration and the 2nd dehydration with execution with the 1st drainage procedure and the 2nd drainage procedure.And the dewatering time of final dewatering process is set longer than the time of the 1st dehydration and the 2nd dehydration.
Afterwards, carry out dry run.Eliminate operation by detecting and crossed the washing foam reliably under the situation that in washing process, produces washing foam surplus, the reliability of heater 65 and Air Blast fan 66 can be guaranteed, in dry run, do not have the washing foam and be attached on heater 65 or the Air Blast fan 66, therefore can operate safely.
In addition, though the height relationships of the installation site of the 1st electrode 62 and the 2nd electrode 64 is that the 1st electrode is located at respect on the lower position of the 2nd electrode 64 in the present embodiment, but also the 2nd electrode 64 can be provided with respect on the lower position of the 1st electrode 62, can access same effect.
In addition, though the present embodiment intermediate roll is the structure of tilted configuration, be arranged at swing roller 30 also can obtain identical effect under the situation of level.
In sum, rolling washing dryer among the present invention is under the situation that foam too much produces, can prevent reliably that heating unit and blowing unit that the washing foam that produces in the cylinder is inwardly put in the air-supply heat tunnel from invading the dipping that produces, prevent the generation of peculiar smell, and can guarantee the reliability of heating unit and blowing unit, therefore not only go in the washing machine, can also be widely used in having the business of clothes drying function with in the laundry machine.
