Foot in water jacket 7 for example is provided with water heater 19.When washing,, the water that is stored in the water jacket 7 is heated, and under suitable water temperature, wash by using this water heater 19.

Side face at cylinder 10 forms a plurality of limbers 10A, and the water that is supplied in the water jacket 7 passes through these limberss 10A, flows in the cylinder 10.And on the inner peripheral surface of cylinder 10, the outstanding baffle plate 10B that is used for washings in the hoisting drum 10 extends the ground mode along left and right directions respectively at circumferencial direction every the equal angles (for example every 120 °) of regulation with (adding up to 3) one by one is provided with.In washing process, by the washings in the cylinder 10 being promoted by baffle plate 10B and carry out repeatedly from the action drum-type that to a certain degree height falls naturally, washings is beaten by the water surface that is stored in the interior water of water jacket 7, with the realization washing of vibrating.

When washing under standard procedure, in a single day above-mentioned washing procedure finishes, and the flushing operation with regard to implementing to remove the detergent ingredients that comprises in the washings enters dehydration procedure afterwards.In dehydration procedure, (for example 300～1000rpm), the moisture that contains in the washings is extruded by centrifugal force, and the moisture of extruding from this washings disperses to water jacket 7 sides by limbers 10A in cylinder 10 rotation at a high speed.

At the side face of water jacket 7, for example in its underpart in face of side, be equipped with the water in the water jacket 7 implemented the electrolysis unit 20 that electricity decomposes.Electrolysis unit 20 has the hollow form electrolytic cell 20B that there are a plurality of battery lead plate 20A inside, with 2 tube connector 20C that electrolytic cell 20B linked to each other with water jacket 7 and the water in the water jacket 7 are flowed in electrolytic cell 20B.Each tube connector 20C is for example side-prominent in face of general horizontal direction.

Battery lead plate 20A carries out chemical reaction, generation active oxygen (O as the water and the chlorine of running water composition under the state of energising when sending into running water electrolysis unit 20 in ₂ ^-) and hypochlorous acid (HClO) etc.As use the water (brine electrolysis) after the electrolytic treatments that generates these products to wash, can prevent that then the dirt of discharging is attached on the washings once more from washings, simultaneously, can be by bactericidal effect to the washings sterilization, thereby, even also can wash having under the abundant washing (-)off properties without washing agent.

At this, this tumbling-box washing machine 1 can be carried out by using brine electrolysis outside standard procedure, need not the process (washing agent zero process) of using washing agent just can wash.In washing agent zero process, for example, after washing process finishes, enter dehydration procedure, do not wash operation.

This tumbling-box washing machine 1 also has the function of the washings drying after the dehydration of making, and the drying device 21 that is used for functions/drying is equipped with in the right side of water jacket 7.Drying device 21 has fan 21A and dry with heater 21B (with reference to Fig. 6), when dry, by drying heater 21B, through fan 21A, the air of heating is blowed in water jacket 7 by drying device 21, and by making cylinder 10 rotations of taking in washings, upset repeatedly.Thus, dry washing material well.

Form the opening 22 of washings discrepancy usefulness at the side face of cylinder 10.And,, forming opening 23 with the opening 4 mutually opposed places of casing 2 at the side face of water jacket 7.The opening 23 of water jacket 7 and the opening 22 of cylinder 10 for example can be by respectively laterally (in Fig. 2 above) but rotatable middle cover 24 and drum cover 25 switches, under the state of enclosing cover 3, middle cover 24 and drum cover 25 full open, washings just can be come in and gone out in cylinder 4.

Middle cover 24 for example roughly becomes circular-arc plate-shaped member for section, and the relative water jacket 7 in end rotatably is installed with thereafter.Under the state of closing middle cover 24, the leading section of middle cover 24 engages with water jacket 7, and 23 one-tenth water-tight types of opening are closed.

In order to open middle cover 24, at first, must open enclosing cover 3.Enclosing cover 3 erects and folding state unlatching down with protecgulum 3B and bonnet 3A with state illustrated in fig. 1.Thus, the opening 4 of casing 2 is opened, and has the space of guaranteeing to open middle cover 24 above water jacket 7.Under this state, the leading section of hand-held middle cover 24 by on carry, middle cover 24 is rotated up, can open the opening 23 of water jacket 7.

Drum cover 25 for example is made of bonnet 25A and protecgulum 25B.Bonnet 25A rotatably is installed with the side face of the relative cylinder 10 in end thereafter.In addition, protecgulum 25B rotatably is installed with the side face of the relative cylinder 10 of its leading section.The leading section of the rearward end of bonnet 25A and protecgulum 25B for example is connected by bar-shaped attaching parts 26, when making the side rotation of bonnet 25A and protecgulum 25B, is attached thereto moving ground, and the opposing party also rotates.And, bonnet 25A and protecgulum 25B for example by force application part (not shown)s such as springs to opening direction (top) application of force.Attaching parts 26 are for example covered by the cover part.

Rearward end at protecgulum 25B forms outstanding claw 25C, and at the leading section formation of bonnet 25A and the corresponding coupling recess 25D of claw 25C of protecgulum 25B.By structure like this, under the state of closing bonnet 25A and protecgulum 25B, claw 25C tangles coupling recess 25D, to keep closing state.

In order to open drum cover 25, open enclosing cover 3 and middle cover 24, the space of opening drum cover 25 must be arranged above cylinder 10 for this reason.Under this state, by pushing away the protecgulum 25B of drum cover 25 downwards, claw 25C can throw off with engaging of coupling recess 25D.

The bonnet 25A of mutual bond-off and protecgulum 25B are because of under the effect to the elastic force of the force application part that applies separately, by further rotation upward of closed condition.By be further rotated bonnet 25A and protecgulum 25B either party under this state, the also together rotation of the opposing party through attaching parts 26 connect as shown in Figure 2, can make the opening 22 bigger unlatchings of cylinder 10.

Closed drum covered 25 o'clock, and only the either party with bonnet 25A and protecgulum 25B is rotated down, and the opposing party who connects through attaching parts 26 also together is rotated down, and claw 25C is engaged with coupling recess 25D.

In the left side of water jacket 7, the locking mechanism 28 that is used for locking (stopping) being housed at the position of rotation place of locking cylinder 10 (but switch drum cover 25 places are drum cover 25 and the opening 23 mutually opposed places of water jacket 7).This locking mechanism 28 has towards the side-prominent pin 28A of rotating shaft 11, forms the recess 13C of the front end that can insert pin 28A at the outer peripheral face of the outer rotor 13B of motor 13.

Pin 28A is along its axis direction (above-below direction) variable bit, and the front end by pin 28A inserts among the recess 13C of outer rotor 13B, and the rotation of lock out motor 13 can lock cylinder 10 in latched position.In addition, in a single day the front end of pin 28A makes a concession the recess 13C of outer rotor 13B, just can remove the locking of cylinder 10.When this tumbling-box washing machine 1 did not move, usually, by locking mechanism 28, cylinder 10 was in the state that is locked on the latched position.

Fig. 5 is the vertical view that the surface structure of operation display board 5 is shown.

Include for example power key 51A of the electric power on/off switching usefulness of this tumbling-box washing machine 1 on the operation display board 5, make the bring into operation initiating key 51B of usefulness of this tumbling-box washing machine 1, that appends before dehydration procedure that the degerming operation of carrying out with brine electrolysis uses adds degerming key 51C, the various washing process that use washing agent to wash are selected the process key 51D of usefulness, import the water for bathing key 51E of waters for bathing operation when washing in the export-oriented water jacket 7 of slave, select the washing agent zero process key 51F of washing agent zero process, the standard procedure key 51G that the choice criteria process is used, select washing of usefulness to do fast key 51H from the dried quick process of washing that the time of washing drying is shortened, switch washing and desiccantly wash dried switch key 51I, the washing key 51J of the time of locking washing procedure, set the rinsing key 51K of rinsing number of times, set the dehydration key 51L of the time of dehydration procedure, select the dry key 51M of the kind of drying process, begin the cleaning key 51P of sweeper mode described later, the rotation key 51Q that can when sweeper mode, operate etc. (below, when these each keys of general designation, be called operated key 51.)。

And, also include on the operation display board 5 and for example show until the remaining time of end of run or the 52A of time showing portion that demonstration was used until the remaining time of this time started when preestablishing the time started of (reservation) operation, when selecting, the washing process that washs with washing agent shows the detergent amount display part 52B that the detergent amount scale is used, the wash time display part 52C that shows the time of washing procedure, the rinsing number of times display part 52D that shows the rinsing number of times, the dewatering time display part 52E of the time of demonstration dehydration procedure etc. (below, when these each display parts of general designation, be called display part 52).

On the assigned position in casing 2 (for example right part of the front-end edge of opening 4), be provided with the outer lid lock device 3D (with reference to Fig. 1) that is used to lock under the state of closing enclosing cover 3.In common laundry processes, during tumbling-box washing machine 1 operation, enclosing cover 3 is locked by outer lid lock device 3D, can not open.This enclosing cover 3 locking device 3D for example are not disengaged when tumbling-box washing machine 1 does not move the locking of enclosing cover 3.

And as above-mentioned, when tumbling-box washing machine 1 did not move, cylinder 10 was locked on the latched position by locking mechanism 28.Therefore, no matter the user is when tumbling-box washing machine 1 operation or when not moving, and except near drum cover 25, all can not see the outer peripheral face of cylinder 10.

For this reason, one of feature of present embodiment is, when this tumbling-box washing machine 1 did not move, can carry out will be by the pattern (sweeper mode) of the cylinder 10 rotatable (unlocking) of locking mechanism 28 lockings.Sweeper mode is the special pattern different with normal mode, under this sweeper mode, cylinder 10 can make cylinder 10 rotate to position of rotation arbitrarily owing to rotatable, on this position of rotation, can directly clean and the outer peripheral face of the opening 23 opposed cylinders 10 of water jacket 7 by opening 23.

Adopt structure like this, need not decompose tumbling-box washing machine 1, just can remove the washing agent sediment and the black mould that are attached on cylinder 10 outer peripheral faces.Therefore, a kind of tumbling-box washing machine 1 of easy purging roller 10 can be provided.

And user's both hands on one's own account just can carry out the cleaning of cylinder 10, therefore can confirm to have removed washing agent sediment and black mould.Owing to can confirm to clean reliably the outer peripheral face of cylinder 10, can prevent the doubt that whether can remove washing agent sediment or black mould veritably that the user entertains.

Fig. 6 is the block diagram that the circuit structure of tumbling-box washing machine 1 is shown.

In tumbling-box washing machine 1, have all control parts 30 of this tumbling-box washing machine of control 1.Control part 30 for example is made of microcomputer etc., includes CPU31, ROM32, RAM33 and timer 34 etc.Store the working procedure of this tumbling-box washing machine 1 operation usefulness of control among the ROM32 in advance.

But operation display board 5 connects on control part 30 input and output ground relatively.Thus, give the signal imported according to user's operating operation key 51 to control part 30, simultaneously, according to signal from control part 30 outputs, the demonstration on the control display part 52.

In addition, the output signal of the enclosing cover switch sensor 3S that uses of the switch of the drum cover switch sensor 25S that uses of the level sensor of for example using to control part 30 input 29, the switch that detects drum cover 25, detection enclosing cover 3 etc. from the water level that detects the water of storing in the water jacket 7.

In addition, by load driving part 35, motor 13, fan 21A, water heater 19, dry heater 21B, feed water valve 14, draining valve 18 and the locking mechanism 28 etc. used are realized being electrically connected as the control object and with control part 30.

Fig. 7 is the flow chart that the control content of the CPU31 in the sweeper mode of an embodiment is shown.

In this embodiment, CPU31 monitors whether cleaning key 51P connects (step S1), and cleaning key 51P is as connecting (being "Yes" among the step S1), just judges this tumbling-box washing machine 1 whether be in operation (step S2).Then, as not operation ("No" among the step S2) of tumbling-box washing machine 1, then CPU31 just is indexed to the yielding position with the pin 28A of locking mechanism 28, removes the locking (step S3) of cylinder 10, simultaneously, connects draining valve 18 (step S4).Thus, the pattern of this tumbling-box washing machine 1 just switches to sweeper mode from normal mode.

CPU31 just can implement electric braking (so-called electric braking) to motor 13 according to the control of drive current.Under sweeper mode, during cleaning key 51P connects ("Yes" among the step S5), CPU31 does not work by the electric braking of relative motor 13, with regard to rotatable drum 10 (step S6).In addition, when cleaning key 51P connects ("No" among the step S5), CPU31 is by the electric braking work of relative motor 13, but do not rotate (step S7) on the position of rotation of carving at this moment with regard to index drum 10.

So, close (in step S8, becoming "Yes") up to enclosing cover 3, the just connection by cleaning key 51P or close of CPU31, come switch motor 13 electric braking connection or close.

Adopt the words of structure like this, the user connects with after cylinder 10 is rotated to desirable position of rotation cleaning key 51P, by making cleaning key 51P disconnect (becoming non-operating state), by electric braking under the state that cylinder 10 is stopped, can clean the outer peripheral face of the cylinder 10 that exposes by opening 4,23.As so moving repeatedly, the whole outer peripheral face of purging roller 10 easily just.

In addition, in sweeper mode, because draining valve 18 is connected, and therefore, even under the situation of the outer peripheral face that waits purging roller 10 by opening 4,23 from outside importing water, also can be with outside the water discharge machine that is stored in the water jacket 7.Therefore, can carry out the cleaning of more suitable cylinder 10.

When enclosing cover 3 is closed (among the step S8 for "Yes"), CPU31 rotates to (step S9) after the latched position by control motor 13 with cylinder 10, the pin 28A of locking mechanism 28 is engaged with the recess 13C of outer rotor 13A, to lock cylinder 10 (step S10).Thus, the pattern of this tumbling-box washing machine 1 switches to normal mode from sweeper mode.

Adopt so by closing enclosing cover 3 finishing the structure of sweeper mode, and compare, saved the time by operating the structure that (for example, being used to finish the operation of the end of a period key of sweeper mode) finish sweeper mode especially, and very convenient.

Fig. 8 is the flow chart that the control content of the CPU31 in the sweeper mode of another embodiment is shown.

In this embodiment, CPU31 monitors that whether cleaning key 51P connects (step T1), when cleaning key 51P connects (being "Yes"), judges whether this tumbling-box washing machine 1 is in run duration (step T2) in step T1.Then, as not operation (being "No" in step T2) of tumbling-box washing machine 1, CPU31 just makes the pin 28A of locking mechanism 28 be indexed to and makes a concession the position, remove the locking (step T3) of cylinder 10, simultaneously, connects draining valve 18 (step T4).Thus, the pattern of this tumbling-box washing machine 1 just switches to sweeper mode from normal mode.

At this moment, cylinder 10 does not rotate from position of rotation at this moment because of the electric braking of motor 13, for example, and only rotation during the rotation key 51Q on the operation display board 5 connects.Promptly, CPU31 monitors whether rotation key 51Q connects (step T5), when rotation key 51Q connects (be "Yes" among the step T5),, will rotate (step T6) under cylinder 10 speed (for example about 10rpm) that when rinsing (during washing or) will be low with than laundry the time by drive motors 13.

So, close (up to become "Yes" in step T7) up to enclosing cover 3, CPU31 is switched on or switched off by rotation key 51Q's, and switching cylinder 10 is rotations or stops.The rotary speed of cylinder 10 can not allow the injured speed of user preferably under the situation of the careless rotation from halted state.

Adopt structure like this, by the operation of rotation key 51Q, can swing roller 10, thus can save time and the time that the user with the hands makes cylinder 10 rotations.Therefore, the outer peripheral face of purging roller 10 more easily.

In addition, the user can stop at the cylinder 10 that rotates on the desirable position of rotation by the operation of rotation key 51Q, and the outer peripheral face of the cylinder 10 that cleaning is exposed through opening 4,23 under this state.And, if finish the cleaning of the outer peripheral face of the cylinder 10 on this position of rotation, then by connecting rotation key 51Q, make cylinder 10 rotations, and on other position of rotation, disconnect rotation key 51Q once more, just can clean the outer peripheral face of the cylinder 10 on this position of rotation.If so move repeatedly, the whole outer peripheral face of purging roller 10 easily just.

In addition, because in sweeper mode, connected draining valve 18, therefore, even when importing the outer peripheral face of purging roller 10 such as water from the outside through opening 4,23, the water that are stored in the water jacket 7 also can be discharged outside the machine.Therefore, can carry out the cleaning of more suitable cylinder 10.

When enclosing cover 3 is closed (among the step T7 for YES), CPU31 control motor 13 to be rotating to cylinder 10 (step T8) after the latched position, the pin 28A of locking mechanism 28 engaged with the recess 13C of outer rotor 13A, to lock cylinder 10 (step T9).Thus, the pattern of this tumbling-box washing machine 1 just switches to normal mode from sweeper mode.

Adopt so by closing enclosing cover 3 finishing the structure of sweeper mode, and compare, saved the time by operating the structure that (for example, being used to finish the operation of the end of a period key of sweeper mode) finish sweeper mode especially, and very convenient.

In sweeper mode, only be not limited to the structure of swing roller 10 during operation rotation key 51Q, for example, also can be for the first time during operation rotation key 51Q (or other operated key), cylinder 10 rotations, and when operating again, the structure that cylinder 10 stops.

And can be when operation rotation key 51Q, the structure that cylinder 10 rotates intermittently or stops.Adopt structure like this, owing to needn't repeatedly operate rotation key 51Q, so cleaning easily.

At this moment, preferably cylinder 10 carries out a speed ratio repeatedly and wants narrow scope (for example 70～80%) along the length of the opening 23 of the water jacket 7 of cylinder direction of rotation, stops a period of time afterwards, once more Xuan Zhuan action.Adopt structure like this, because of rotating or stop, the outer peripheral face of the cylinder 10 that exposes gradually by cleaning process opening 23, the whole outer peripheral face of purging roller 10 easily.

Can be to rotate a circle from latched position with the cylinder 10 that rotates because of operation rotation key 51Q abovely to reply mutually, cylinder 10 automatically be rotated on the latched position, and lock by locking mechanism 28.At this moment, cylinder 10 rotates a circle above, and the user can identify the whole outer peripheral face that has cleaned cylinder 10, can be to the same position cleaning phenomenon several times of outer peripheral face.

In addition, if the structure of swing roller 10 under the situation of 2 above keys of operation (for example rotating key 51Q and initiating key 51B) only, then can prevent accidentally swing roller 10 and infringement user's phenomenon has improved security.In addition, above-mentioned key more than 2 as be configured to spaced apart not with the hands and the interval that can not operate simultaneously, then can further improve security.

The schematic diagram that Fig. 9 uses in the method for the side face formation limbers 10A of cylinder 10 for explanation.

Form when the cylinder 10, at first, for example with respect to the flat all panels 101 that constitute by stainless steel etc., form the processing of limbers 10A etc. after, should week panel 101 bend to roughly cylindricly, and its limit, two ends is bonded with each other.Afterwards, with respect to roughly becoming all panels 101 cylindraceous, the end plates (not shown) that constitute both ends of the surface are engaged, to form cylinder 10.

When the side face of cylinder 10 formed limbers 10A, at first, with punch process etc., flat relatively all panels 101 were split into the limbers 10A of (penetrating) circular from one side 101A side.At this moment, on the another side 101B of all panels 101, shown in Fig. 9 (a), form from the outstanding burr 102 of the circumference of limbers 10A.

Afterwards, from the another side 101B side of all panels 101, carry out circumference with limbers 10A to the side-prominent processing of one side 101A (so-called plunging processing).Thus, shown in Fig. 9 (b), the circumference of limbers 10A roughly becomes coniform outstanding towards one side 101A side, simultaneously, from the side-prominent burr 102 of the one side 101A of all panels 101 towards another side 101B side.All panels 101 after plunging is handled become inboard mode bending with its another side 101B side, roughly become cylindric.

As forming cylinder 10, can become the not outstanding shape of burr 102 on any one face of the inner peripheral surface of cylinder 10 and outer peripheral face with above-mentioned method.Thus, when can prevent that washings in the cylinder 10 from sustaining damage, the user prevents that the burr 102 that is highlighted from stabbing when the outer peripheral face of purging roller 10, improved security.

The present invention is not limited to the content of above embodiment, in the scope that the present invention put down in writing, can make various changes.

For example, be not limited to be provided with the structure of sweeper mode, can make cylinder 10 rotations with the structure of manual or electronic 28 pairs of cylinders of mechanism, 10 lockings that unlock, easily clean its outer peripheral face as adopting at least.

Locking mechanism 28 is not limited to the structure by pin 28A locking, can adopt other the mechanical mechanism that is suitable for gear or abutment damper etc., also can use the such electronic mechanism of electric braking.

Sweeper mode is not limited to reply the structure that finishes mutually with closing enclosing cover 3, for example can be and closes that middle cover 24 is replied mutually and the structure that finishes, also can be to reply mutually with the operated key of operating provision and the structure that finishes.

In the sweeper mode, can be water to be stored in the water jacket 7 by water supply pipe 15.At this moment, the side face of cylinder 10 can be by the water-soaked that is stored in the water jacket 7.Therefore, the user is by swing roller 10, and in the whole peripheral surface of soaking cylinder 10, the outer peripheral face of the cylinder 10 that soaks by cleaning need not be from the outside imports water etc. through opening 4,23 and just can easily clean.

At this moment, the water that is stored in the water jacket 7 can decompose by electrolysis unit 20 electricity, to generate brine electrolysis.Adopt structure like this,, can remove washing agent sediment or black mould well by clean the outer peripheral face of the cylinder 10 that soaks with brine electrolysis.

And, can have will be stored in water in the water jacket 7 not only soak the side face of cylinder 10, and water directly can be added to the mechanism on the outer peripheral face of cylinder 10.At this moment, can be the structure that will directly add to from the water that water supply pipe 15 imports on the outer peripheral face of cylinder 10, also can be the structure that can import the water in the water jacket 7 that electricity decomposes by electrolysis unit 20.

Cylinder 10 only covers 25 o'clock rotatable structures at closed drum in this way, then by rotating, can prevent drum cover 25 breakages under the state of opening drum cover 25.At this moment, it can be detection signal according to drum cover switch sensor 25S, judge the structure whether drum cover 25 closes, do not using drum cover switch sensor 25S, when state bottom roll 10 rotations that drum cover 25 is opened, can be by detect because of drum cover 25 by water jacket 7 tangle, thereby cylinder 10 do not rotate the load that produces on the motor 13, judges the structure that cylinder 10 is opened.

Water in the water jacket 7 is not limited to the structure of draining by the switch of draining valve 18, for example, can be the structure of draining by driving draining valve.

In the above-described embodiments, the tumbling-box washing machine 1 with drying device 21 is illustrated, but the present invention is also applicable to the tumbling-box washing machine that does not have functions/drying.
