Next, explain in having the washing machine of said structure the bucket cleaning procedure that foreign matter cleans on the internal face of the inside and outside wall of swing roller 1 and steel ladle 3 that hardens with reference to the flow chart of Fig. 6.
Among Fig. 6, at first by the selected bucket of the 2nd pattern configuration switch 21i cleaning model (step S601) in the input setting device 21.Control device 20 advances water by intake tunnel 15 from water intaking valve 14 in steel ladle 3, the identical or above designated water level (as 150mm) of peak level in when such water inlet will enter with normal washing operation.After water inlet reached designated water level, the user pressed starting/pause switch 21e and makes operation suspension, opens cover 7, directly drops into cleaning agent (step S602) in swing roller 1.Why water inlet will enter high like this designated water level, is in order to improve the immersion effect of cleaning fluid as far as possible.Afterwards, the user closes cover 7, and then presses starting/pause switch 21e, enters next procedure (step S603).
Because what cleaning agent used is the chloride-based bleaching agent,, might make resin generation deterioration or damage stainless steel if when directly dropping in the swing roller that washing powder cabin that resin makes and stainless steel make.Therefore, preferably carry out above-mentioned operating sequence.
Next, in order to make cleaning agent dissolving, to form cleaning fluid, control device 20 makes swing roller 1 with for example 35 rev/mins 5 minutes (step S603) of speed rotation; Then, the internal face of swing roller is soaked, make swing roller 1 stop the rotation 4 minutes (step S604: rotation stop stroke) again in order to make cleaning fluid.Thereafter, it is that (step S605) just changeed in clockwise rotation that swing roller 1 is carried out when the front is seen at setting-up time (for example 20 seconds) with the 1st setting rotating speed (as 35 rev/mins), is rotated counterclockwise i.e. counter-rotating (step S606) with the 1st identical setting rotating speed in identical setting-up time again.These two step S605 and S606 form the 1st washing stroke.In the 1st washing stroke, just change, reverse by swing roller 1 is hocketed, can be not only the inside and outside wall of swing roller 1 be cleaned up, the current of left and right directions can also also clean up the jog on its inside and outside wall.
Next, control device 20 judges whether to have surpassed setting-up time A (for example 2 minutes) (step S607), if do not surpass (being that judged result is a "No"), then repeated execution of steps S605 and S606.Like this, when the switching that the carrying out of swing roller 1 just changes, reverses, will produce turbulent flow, thereby can improve the cleaning performance of swing roller 1.When the judged result among the step S607 is "Yes", promptly surpasses under the occasion of setting-up time A (as 2 minutes), just under the occasion that has repeated 3 times respectively of just changeing, reverse of swing roller 1, then finish the 1st washing stroke, enter the 2nd washing stroke.
In the 2nd washing stroke, it is that (step S608) just changeed in clockwise rotation when the front is seen that control device 20 at first makes swing roller 1 do in setting-up time (for example 30 seconds) with the 2nd setting rotating speed (as 140 rev/mins), the above-mentioned the 2nd sets rotating ratio the 1st sets rotating speed and wants high, and can produce circulating water flow between the internal face of the outside wall surface of swing roller 1 and steel ladle 3; Next, in identical setting-up time, be rotated counterclockwise i.e. counter-rotating (step S609) with the 2nd identical setting rotating speed.In the 2nd above-mentioned washing stroke, under the friction and action of centrifugal force that when swing roller 1 rotation, produces, to produce circulating water flow between the internal face of the outside wall surface of swing roller 1 and steel ladle 3, groove 300 on the above-mentioned in addition steel ladle 3 also will produce turbulent flow and eddy current in circulating water flow, just change, reverse by swing roller 1 is hocketed again, just can be not only the internal face of steel ladle 3 be cleaned up, the jog on the internal face also can also be cleaned up by the current on the left and right directions.
Next, control device 20 judges whether to have surpassed setting-up time B (as 2 minutes) (step S610).If do not surpass (being that judged result is a "No"), then repeat step S608 and S609.Like this, connect the turbulent flow that produces when changing, can improve the cleaning performance of steel ladle 3 by just changeing at swing roller 1, reversing.If the judged result among the step S610 is "Yes", when promptly having surpassed setting-up time B, that is the rotating and reverse under the occasion of having carried out 2 times respectively of swing roller 1, enter step S611, judged whether to surpass another long setting-up time C (as 10 hours).
But, if also do not surpass setting-up time C (being that judged result is a "No"), the rotation that then turns back among the step S604 stops stroke, once more the 2nd washing stroke of the 1st washing stroke of repeated execution of steps S605, S606, S607 and step S608, S609, S610.Like this, in very long setting-up time C, the 1st washing stroke, the 2nd washing stroke, and rotation stop to repeat many times in the above-mentioned very long setting-up time of being combined in of stroke, thereby the washing powder residue that hardens and mildew etc. can be cleaned up.
On the other hand, under the occasion that surpasses setting-up time C (be among the step S611 judged result be "Yes"), then enter draining stroke (step S612), control device 20 is discharged to outside the machine by the cleaning fluid that drainage channel 12 and draining valve 13 will contain the foreign matter that strips down from the internal face of the inside and outside wall of swing roller 1 and steel ladle 3.Rotating speed (as 900 rev/mins) rotation a period of time (as 3 minutes) (step S613: the rotating distance of swing roller) when next, making swing roller 1 with dehydration.Then, with the same among the step S602, control device 20 is intake in steel ladle 3 (step S614: water inlet stroke) through intake tunnel 15 from water intaking valve 14, the identical or above designated water level (as 150mm) of peak level when always making water level reach with washing operation normally.
Next, with the same in the 2nd washing stroke, set rotating speed (as 140 rev/mins) with the 2nd and in the time of setting (as 30 seconds), make swing roller 1 carry out turning clockwise when the front is seen just to change (step S615: the rotating distance of swing roller); Then, make it again to be rotated counterclockwise i.e. counter-rotating (step S616: the rotating distance of swing roller) at identical setting-up time with the 2nd identical setting rotating speed.
Operate the number of times (as 4 times) that to set by the rinsing that above-mentioned draining stroke, water inlet stroke, the rotating distance of swing roller make up.After finishing the number of times of setting (judged result among the step S617 is a "Yes"), carry out draining stroke (step S618).Arrive this, a bucket cleaning procedure that is used to clean the foreign matter that hardens on the internal face of the inside and outside tube wall surface of swing roller 1 and steel ladle 3 just comes to an end.
Like this, the user only need set the bucket cleaning model by the 2nd pattern configuration switch 21i of input setting device 21, the bucket cleaning procedure just can carry out automatically, need not manually to set operations such as water inlet, cleaning, draining, rinsing, just can be rotated the cleaning stroke of cylinder 1 and steel ladle 3.
In addition, in above-mentioned described embodiment, though the shape of the groove 300 of steel ladle 3 be side wall surface 300a with respect to bottom surface 300b rectangular or acute angle, but practical structure can be not limited to the structure shown in the present invention, as long as produce turbulent flow and eddy current in the circulating water flow that when swing roller 1 is set the rotating speed rotation with the 2nd, can between the internal face of the outside wall surface of swing roller 1 and steel ladle 3, produce, adopt other shapes also to be fine.
In addition, though the motor 5 in the present embodiment is to describe as example with the occasion of using dc brushless motor, but, also can be subjected to qualification of the present invention, for example use direct current brush motor and induction machine and change the words of its drive unit and method, technical conceive of the present invention also can use, and also can reach the effect identical with the present invention.
In addition, each stroke in other formation described in the present embodiment and the bucket cleaning procedure (comprise designated water level, set rotating speed, setting-up time) also is an illustrative, and it revises example and variation also belongs to by in the determined technological thought of the present invention of following claim book.
In sum, roughly be located at for the foreign matters such as washing powder residue on the internal face of the inside and outside wall of the swing roller on horizontal direction or the incline direction and steel ladle and mildew at rotary middle spindle for hardening, washing machine of the present invention can be realized effect that it is washed fully, therefore goes in the equipment such as rotary drum-type washing machine.
