The specific embodiment
The schematic configuration of the tumbling-box washing machine in one embodiment of the present of invention has been shown among Fig. 1.Wherein, steel ladle 3 is bearing in the washing machine body 2 with oblique heeling condition by not shown suspension construction, and the cylindrical shape swing roller 5 at the band end is bearing in the steel ladle 3 in rotation mode freely.Swing roller 5 is being driven by the drum drive motor 4 that is installed in steel ladle 3 back sides and is rotating, and its rotary speed can change, and direction of rotation also can be switched.In addition, swing roller 5 is inclined to set, as shown in FIG. like that downward-sloping with tilt angle theta with respect to horizontal direction H to the back side one side that constitutes the bottom surface from front one side of opening mouthful of its rotating shaft direction R.Therefore, will be located at switching gate 8 freely on the inclined plane 2a of the face side that constitutes washing machine body 2 when opening, only need bend over slightly just washings can be put in the swing roller 5/or therefrom taking-up.In addition, because the face side of tumbling-box washing machine 1 also need not to guarantee unnecessary space, therefore can constitute a kind of tumbling-box washing machine 1 that can be arranged in the narrow space such as washing room.
In above-mentioned washing machine body 2, except above-mentioned inscape, also be provided with: the water inlet unit 6 that is used in steel ladle 3, adding water; Be used for the water in the steel ladle 3 is discharged to outside drainage cell 7; With the parts such as control device 10 (see figure 2)s that are used to control operating process such as washing operation, rinsing operation and dehydrating operations.During laundry, open described gate 8, in swing roller 5, drop into washings, add the washing powder of ormal weight again, start washing operation.Described control device 10 just will be controlled a succession of operating process, and tumbling-box washing machine 1 can be realized automatic operation.
The structured flowchart of described control device 10 has been shown among Fig. 2.Control module 11 is made of micro computer, and this control module 11 uses the control program that is stored in the memory cell 15 to power switch unit 12 output control instructions according to setting input information from the operator scheme selection of setup unit 13 inputs etc.Power switch unit 12 is made of switch elements such as SCR, according to from the control instruction of control module 11 outputs to controls of switching on/cut off the power supply such as drum drive motor 4, water intaking valve 26, draining pumps 27.Below with reference to Fig. 1～Fig. 4 the control operation of being carried out in tumbling-box washing machine 1 by control device 10 is elaborated.
During laundry, open gate 8, in swing roller 5, drop into washings, drop into the washing powder of ormal weight in the washing powder input port that is located on the water unit 6 into, operating power switch 18 connection power supplys; Then, select/the input operation pattern according to the kind of washings by the setup unit 13 that is located in the washing machine body 2 lip-deep guidance panels, and the instruction of input start-up operation.At this moment, the corresponding control program of input is read and set to control module 11 from memory cell 15, begins executive control operation according to control sequence.At first, control module 11 makes swing roller 5 rotations, detects the amount of washings.Because of the amount difference of washings, the load that drum drive motor 4 is born also can change.According to such load variations, cloth amount detection unit 16 can detect the amount of washings.Detected washings amount is imported in the control module 11, and is stored in the memory cell 15.
What at first carry out is washing operation.In washing operation, carry out the rotation control of water inlet control shown in Fig. 3 and swing roller 5.Wherein, number W1, the W2 among Fig. 3 ... be the step number of expression water inlet control sequence, R1, R2 ... be the step number of expression rotation control sequence, adopted consistent with it numbering in the following explanation.
Control module 11 at first sends the control instruction of opening water intaking valve 26, add water in steel ladle 3 to power switch unit 12; Simultaneously, output drives the control instruction that swing roller 5 rotates with the 1st regulation rotary speed in power switch unit 12.By such control operation, water intaking valve 26 is opened, and from adding running water with the joining water inlet pipes in water inlet unit 6, and then the water (W1) of washing powder has been sneaked in adding to steel ladle 3 in.In addition, be that swing roller 5 rotates (R1) with the 1st regulation rotary speed under the driving of drum drive motor 4, and direction of rotation switching cycle is according to the rules just changeing, switching between the reverse directions (R2) with water inlet is carried out concurrently.
The 1st above-mentioned regulation rotary speed is such rotary speed, promptly be contained in washings in the swing roller 5 when swing roller 5 rotations, can be raised along direction of rotation, on moving to the internal face that drops to again when its deadweight surpasses on height and position of rotatory inertia and centrifugal force below the swing roller 5.When the diameter of swing roller 5 was 500 ± 50mm, above-mentioned the 1st regulation rotary speed was about 35 ± 5 rev/mins.When controlling the rotary speed that reaches such by drum drive motor 4 is rotated, washings just will carry out above-mentioned motion.
On a plurality of positions on the internal face of swing roller 5, be provided with and stir thrust 9, when swing roller 5 rotates with the 1st fixing speed, stirring thrust 9 just will tangle and the contacted washings of the internal face of swing roller 5, it is upwards mentioned along direction of rotation, and washings is lifted to its deadweight and will falls down above time on the height and position of rotatory inertia and centrifugal force.Like this, the washings that are deposited in the swing roller 5 are mentioned in succession, are thrown from eminence, stacking states will take place loose in, the impact energy that produces when falling down is applied with the effect that " knocking " washs to washings.If rotary speed is slower than the 1st regulation rotary speed, can not produce the effect that washings is mentioned, on the contrary, when rotary speed is faster than the 1st regulation rotary speed, centrifugal force will become greatly, and washings will become the state that is adjacent on the internal face of swing roller 5, does not drop.
Because also continuing to add water in steel ladle 3 when swing roller 5 rotates, the water that is added in the steel ladle 3 also can enter swing roller 5 inside from the many through holes 17 on the wall that is located at swing roller 5.Therefore, when the swing roller 5 with the 1st regulation rotary speed rotation constantly washings is mentioned, when throwing, washings can become when falling by the moistening equably state of water.
The water level that is added to the water in the steel ladle 3 is detected by the water level detecting unit 19 that is located in the steel ladle 3.When water level becomes than low the 2nd predetermined water level of the 1st predetermined water level of implementing washing operation (W2), water level detecting unit 19 can be exported detections and send in the control module 11.In view of the above, control module 11 is to the control instruction of power switch unit 12 outputs " close water intaking valve 26, stop into water ", and making into, water stops (W3).
When the water level of the water in being added to steel ladle 3 reaches the 2nd predetermined water level, control module 11 is sent to drum drive motor 4 and is driven the control instruction of swing roller 5 with the rotation of the 2nd regulation rotary speed, and swing roller 5 is promptly with the 2nd regulation rotary speed rotation (R3) faster than the 1st regulation rotary speed.Washings can be adjacent to the rotary speed on the internal face of swing roller 5 when the 2nd regulation rotary speed was swing roller 5 rotations under action of centrifugal force.When the diameter of swing roller 5 was 500 ± 50mm, described the 2nd regulation rotary speed was 90～140 rev/mins.When swing roller 5 during in such the 2nd regulation rotary speed rotation, because washing powder dissolves in the less inflow, therefore will produce the washing powder solution of high concentration, the rotation that is accompanied by swing roller 5 will have current to take place, thereby become the state that is easy to generate foam.
As shown in Fig. 1 and Fig. 4, the direction of the direction of rotation of the foot of steel ladle 3 and swing roller 5 (arrow A direction) quadrature is provided with rhone 20.Because sidewall (retaining wall) 20a and the water (flow) direction (arrow B direction) of rhone 20 bump, this sidewall 20a will produce turbulent (arrow C) in current, and having added will be because of the turbulent foaming phenomenon that produce in the high concentration washings of washing powder.
In general, the washing powder molecule is made of hydrophilic group and lipophilic group.In water and in the washing powder solution that forms, the washing powder molecule fitly is arranged on the interface (water surface), the washing powder molecule of not arranging then exists with the form of single or group in water at detergent dissolving.Washing powder molecule on the interface got except that the time, washing powder molecule in the water can replenish at once to Interface Moving.When the bubble that is taken place by turbulent flow is admitted in the above-mentioned washing powder solution, bubble can rise, arrive the interface, the washing powder molecule that fitly is arranged on the interface can keep original ordered state to transfer on the membranous wall of bubble, thereby forms the washing powder solution foam.Because arranging washing powder molecule as much as possible on such washing powder solution foam, washing powder concentration also will increase.After the washing powder solution foam was taken away a part of washing powder molecule, the washing powder molecule in the solution can move past at once, replenishes.Therefore, when bubble is constantly sent, the washing powder solution foam also will constantly form.
A large amount of washing powder solution foams that produce are full of the space between steel ladle 3 and the swing roller 5, and constantly rise, and constantly enter in the swing roller 5, on washings from the face side opening of opening.With the 2nd regulation rotary speed when rotation, washings is and is adjacent under the state on the internal face at swing roller 5, and the washing powder solution foam enters the hollow space of the central authorities of swing roller 5 easily.And, owing to the washing powder solution foam also can be penetrated on the washings by break-through through hole 17, so all will adhere to the washing powder solution foam on the tow sides of washings.Obtained moisteningly in the motion that washings swing roller 5 formerly causes with the 1st regulation rotary speed rotation equably in water, when adhering to the washing powder solution foam more thereon, the washing powder composition will become and be penetrated into the inside of washings easily.
When making the washing powder solution foam be penetrated into the surface of dirty washings or when inner, lipophilic group will combine with oily dirt and the particle dirt that is attached with oiliness, with its pull-up, take away.In addition, when breaking when the washing powder solution foam is passing washings, the washing powder solution of high concentration will dye in the washings, and dirt will become the state of washing off easily, therefore, washings can be cleaned up by the washing powder solution foam.Like this, by washing powder solution being become the very big washing powder solution foam of volume earlier, adhering to again/be penetrated on the washings in the swing roller 5, the washing powder composition has just been given play to effect to dirt easily, the washing powder solution of high concentration also infiltrates in the clothing easily, thereby can suppress to wash uneven phenomenon, improve cleansing power, and can the cripetura wash time.
Thereby enter the state continuance after the 1st stipulated time (R4) that makes washings be stained with the washing powder solution foam in the swing roller 5 at the washing powder solution foam that makes a large amount of generations, control module 11 will be exported the control instruction of opening water intaking valve 26, water in the steel ladle 3 being replenished on power switch unit 12, water intaking valve 26 is opened, begins to replenish water inlet (W4).The water levels that added in the steel ladle 3 of water are detected by water level detecting unit 19, and when detecting water level and reach the 1st predetermined water level (W5), water level detecting unit 19 is sent into testing result in the control module 11; Then, from control module 11 control instruction taking place, water intaking valve 26 is closed, stops into water (W6).
The inflow that described the 1st predetermined water level adapts for the amount with washings.Because cloth amount detection unit 16 initial detected washings amounts have stored in the memory cell 15 as described above, therefore, when inflow that adapts when the amount that detects with washings that is the 1st predetermined water level, water inlet is stopped.
When the additional water inlet of carrying out in order to reach described the 1st predetermined water level begins, control module 11 makes the output control instruction of swing roller 5 with the rotation of the 1st fixing speed to power switch unit 12, drive swing rollers 5 with the 1st regulation rotary speed rotation (R5) by drum drive motor 4, and the driving (R6) that between positive and negative direction, commutates of commutation cycle according to the rules.By swing roller 5 is rotated with the 1st regulation rotary speed, can be applied with washings and to knock cleaning function what it was put on, throws; In addition, the time interval by is according to the rules being switched direction of rotation on positive veer, reverse directions, make the washing powder solution foam equably attached on the dirt in the washings, replenish water inlet again, make washings reach the necessary water yield of washing, in the 2nd stipulated time, carry out washing operation (R7) then.After surpassing for the 2nd stipulated time, control module 11 will send the control instruction that drum drive motor 4 is stopped the rotation to power switch unit 12, and swing roller 5 stops the rotation (R8), and washing operation promptly comes to an end.
Washing operation then carries out rinsing operating process and dewatering operation course after finishing, and finishes until whole operating process.Carry out because rinsing operating process and dewatering operation course can adopt with the same mode of prior art, thus this just omission to the explanation of these two operating process.
In the control sequence of Miao Shuing, before water inlet reaches the 2nd predetermined water level, make swing roller 5 be rotated this control operation and also can omit in the above with the 1st regulation rotary speed.But so, washings just can not be immersed in the water in advance, and the penetrating power of washing powder solution foam in washings that generates also will descend.
In addition, though in the above embodiments, in order to produce the washing powder solution foam expeditiously, adopted sidewall 20a by rhone 20 in current, to produce the method for turbulent flow, but also can be as shown in Figure 5 divide at the inner bottom part of steel ladle 3 like that form the protuberance 28 that the direction of rotation generation with swing roller 5 intersects.By means of such protuberance 28, can in current, produce very big turbulent flow, thereby can make the formation efficiency of washing powder solution foam higher.In addition, even steel ladle 3 is not provided with the structure of rhone 20 specially, under the effect of the turbulent flow that protuberance 28 produces, also can generate the washing powder solution foam.
In addition, in the above-described embodiments, though the structure that swing roller 5 is inclined to set,, even under the occasion that swing roller 5 is provided with in the horizontal direction, also can reach same cleaning performance by the rotary speed that changes swing roller 5.
In sum, the present invention produces the washing powder solution foam by the rotation control to water inlet control and swing roller, and cleaning force is improved, thus can provide a kind of can the cripetura wash time, cut down the tumbling-box washing machine of long-time running cost.
