Above tank 3, be provided with for the confession water unit 7 to tank 3 interior water supply.For water unit 7 by feed water valve 7b, the washing agent resettlement section 7a supplied water by the switching of feed water valve 7b and by the washing agent in the 7a of washing agent resettlement section with supply water together be supplied to tank 3 water supply path 7c form.
Below tank 3, be provided with for the drainage cell 8 from the interior discharge water of tank 3.Drainage cell 8 is connected in the bottommost of tank 3 drainpipe 8a and draining valve 8b by an end form.Draining valve 8b after cleaning step finishes, rinse step while finishing etc. in case of necessity, under open mode by water tank 3 in via drainpipe 8a discharge, stop down in off position draining.
And, be provided with the drain filter 8c that can unload from the outside of main body 1 in the downstream of drainpipe 8a.Drain filter 8c is for collecting broken the end of a thread that drainage procedure contains etc.
Be provided with drying section 9 below the rear side of tank 3.Drying section 9 has pressure fan 9c, air-supply path 9d, introducing port 9e, export mouth 9f, dehumidification portion 9g and heating part 9h.
Be provided with circulation waterway 31 and the water in suction tank 3 water in tank 3 is ejected in swing roller 4 circulating pump 30 of delivering to circulation waterway 31 below the front surface side of tank 3.Circulating pump 30 is fixed on as the platen 1a of the bottom of main body 1 upper, and the water in suction tank 3 is also delivered to circulation waterway 31 via recirculated water bleed pipe 32.Then, the water of sending here is ejected in swing roller 4 from the opening 15 of swing roller 4 by circulation waterway 31.
Specifically, the recirculated water bleed pipe 32 of circulation waterway 31 is connected with the jet 51 that the front bulkhead 3f of the end periphery of opening 13 being positioned at tank 3 arranges from door 5 sides.And, as the arrow A of Fig. 1, via the stream formed between the back side of the front bulkhead 3f at tank 3 and the surface corresponding to the front bulkhead 4f of the swing roller 4 at the back side of front bulkhead 3f, water is ejected in swing roller 4.
Thus, when each steps such as cleaning preparation, cleaning, rinsing such as the detection of carrying out the cloth amount etc., make as required the water in tank 3 be circulated, thereby prevent deflection, raising cleaning, the rinsing performance of dissolving, the washings in advance of washing agent.
In addition, come the jet 51 of the water of self-circulating water bleed pipe 32 to be arranged on the position that not interior with swing roller 4 washings contacts.Thus, can prevent from tangling washings when cleaning, rinsing, drying steps and upset action or damage washings.
In addition, in the situation that from jet 51 merely to the interior injection water of swing roller 4, as shown in the arrow B of Fig. 1, only can, to the localized ejection water of the washings in swing roller 4, therefore can not give full play to circulating effect.On the other hand, when for from jet 51 injection water and for example using while having the injection nozzle of a plurality of jets 51 in large area, the imposing manner of water descends, as shown in the arrow C of Fig. 1, and only can be to the localized ejection water of the washings in swing roller 4.Therefore, make the pump pressure of circulating pump 30 raise injection water forcefully to get final product, but, when pump pressure is raise, cost raise.Therefore, in present embodiment 1, example in the circulating pump 30 that the water in making tank 3 is circulated if carry out the DC brushless motor of rotating speed control, is adjusted flow, the flow velocity of sprayed water.Thus, even not being set in addition, nozzle can not supply feedwater by the washings large tracts of land in 30 pairs of tanks of circulating pump 3 and to optimum position yet.Its result, cleaning performance and rinsing performance improve.In addition, can therefore useless power consumption can not be suppressed to the space that do not have washings invalidly for feedwater, and the generation of the abnormal foam that caused by the water that contains washing agent can be suppressed.
In addition, be provided with the cloth amount test section (not shown) that the amount to putting into the washings in swing roller 4 is detected in main body 1.
Below, an example of the detection method of cloth amount test section is described.
At first, motor 6 is rotated to driving.Now, the rotating speed of swing roller 4 is elevated to degree, for example 100rpm～140rpm left and right that makes washings be attached at the internal perisporium 4c of swing roller 4.And, after lasting rotary compasses is fixed time with above-mentioned rotating speed in the rotation that makes swing roller 4, cut off the energising to motor 6.Now, swing roller 4 utilizes the inertia of swing roller 4 to proceed rotation.Thus, swing roller 4 becomes the state that motor 6 is rotated.Afterwards, swing roller 4 due to the friction etc. resistance stop the rotation.In addition, about the time till stopping from energising stopping to swing roller 4, when the amount of washings is many this time long, and when the amount of washings is few this time short.Therefore, the difference of utilizing swing roller 4 to stop the required time and the proportional characteristic of the amount of washings detect the amount of washings.
And, in the rear side of the bottom of tank 3 3b, be provided with the water level detecting section 10 that the water yield to being supplied in swing roller 4 is detected.Near the 10a of air trap section at assigned position place that will be arranged on the bottom 3b of swing roller 4 by flexible pipe 10b is connected with pressure detecting portion (not shown) to fetch and forms water level detecting section 10.Pressure detecting portion for example consists of the integrated ferrite of the part of the bellows with being moved by pressure and the coil of the fixation side of surrounding ferritic periphery.And, utilize the inductance between ferrite and coil to change shift motion apart from being converted to the pressure in the 10a of air trap section.The 10a of air trap section of water level detecting section 10 is not in the situation that there is no water in aeration status, and the output of pressure detecting portion is fixed.
Like this, water level detecting section 10 is generally detected by the interior pressure of the measurement 10a of air trap section of air trap mechanism, the time of playing till changing from stable venting pressure by the interior pressure to the 10a of air trap section is measured, and can not be subject to the impact ground of the deviation of level sensor to calculate rightly the water level in tank 3.
In addition, about the output of water level detecting section 10, according to swing roller 4 whether rotate, the rotation of swing roller 4 in cleaning, the rinse step such as rotating speed exports and changes.Therefore, control device 11 described later has a plurality of frequencies corresponding with the rotating speed of swing roller 4 and the table of water level.That is to say that no matter swing roller 4 can both sensed water level in static or in rotation.
Be provided with rotating speed test section 21 and control device 11 for detection of the rotating speed of swing roller 4 above tank 3.
Below, use Fig. 2 to describe the structure of the control device 11 of the tumbling-box washing machine of present embodiment.

The signal of time measurement section 11f, water level detecting section 10 and the rotating speed test section 21 of control part 11a based on from Measuring Time is supplied water, the driving of draining and swing roller 4.Thus, can grasp each action, the required time regularly of the various sensors such as the water level detecting section 10 that comprises, rotating speed test section 21 output, and control by the time input and output that have of administrative institute.Its result, can control rightly from cleaning step and start the time finished to dehydration, thereby obtain stable cleaning performance.
Below, use Fig. 3 and with reference to Fig. 1, action, the effect of the tumbling-box washing machine that forms as described above described.
In addition, in the present embodiment with whether to have a functions/drying irrelevant, the explanation of therefore omitting drying steps.
In addition, in the following description, while describe as dewatering carrying out the action that draining dewatered.And, for the dewatering of distinguishing in the action of dewatering in rinse step and dehydration moves, dewatering in rinse step is moved as middle dewatering, the dewatering in dehydration is moved to describe as final dewatering.
At first, opening door 5 puts into the washings such as clothing in swing roller 4 from the opening 13 of tank 3.Then, when operation start switch (not shown) and during entry into service, the cloth amount of being undertaken by the rotation of accompanying rotation cylinder 4 detects the cloth amount of washings.
Afterwards, open feed water valve 7b, according to the cloth amount of detected washings, the water of the predefined water yield is supplied in tank 3.Now, utilize the washing agent that will be housed in the 7a of washing agent resettlement section that supplies water to drop in tank 3.
Water level in tank 3 is for regulation when above, and control part 11a makes circulating pump 30 actions accelerate the dissolving of washing agent.In addition, control part 11a controls motor 6 swing roller 4 is rotated to driving.Thus, washings in swing roller 4 is called repeatedly to the stirring action of rolling, the stirring action that is called rolling is after the washings in swing roller 4 are stirred projection 4b and lift to direction of rotation, due to deadweight, from the top of swing roller 4, falls the action the water surface of the water that is dissolved with washing agent.Its result, wash dirty to infiltration and the washing agent of washings from ejecting of washings by washing agent.Then, after the process official hour, control part 11a opens draining valve 8b via the 11d of power switch section, and the sewage in tank 3 is discharged from drainpipe 8a, finishes cleaning step.
Below, use Fig. 3 that cleaning step step afterwards is described.
Fig. 3 means the sequential chart of the action of the rinse step of the tumbling-box washing machine in embodiments of the present invention 1 and dehydration.
In rinse step for the first time, carry out successively the centre dehydration and supply water and stir each action, wherein, this centre dehydration is mainly dewatered, and rinsing is mainly carried out in this water supply stirring.
At first, as shown in Figure 3, in the action of centre dehydration, control part 11a starts balance and controls, and this balance is controlled and is used for the vibration weakening produced by being present in when swing roller 4 interior washings make swing roller 4 High Rotation Speed.Usually for example make swing roller 4 be rotated with the rotating speed of 50rpm, utilize the common vibration such as detection swing rollers 4 such as the vibration detecting sensors such as acceleration transducer (not shown), carry out thus balance and control.
After balance has been controlled, control part 11a makes the rotating speed of swing roller 4 for example be increased to the rotating speed of the regulation of 900rpm left and right, by centrifugal force, from washings, removes and anhydrates.After reaching the rotating speed of regulation, maintain the rotating speed of swing roller 4 in during official hour t1.Afterwards, stop the driving of motor 6.Then, when swing roller 4 stops the rotation, the release of middle dehydration, transfer to ensuing water supply and stir.Now, washings is the state that is attached at the internal perisporium 4c of swing roller 4.
In the action of supply water stirring, at first, while control part 11a makes swing roller 4 be rotated and open feed water valve 7b to retaining in tank 3 to fixed-direction.Now, the rotating speed of swing roller 4 is to make washings be attached at for example 80rpm left and right of the internal perisporium 4c of swing roller 4.
And, when to the interior retaining of tank 3, by water level detecting section 10, water level h1 being detected, control part 11a controls feed water valve 7b and stops supplying water, and meanwhile starts circulating pump 30.Thus, from 51 pairs of swing rollers of ejiction opening 4, interior washings sprays water.Now, make the rotating speed of swing roller 4 for example be increased to the 170rpm left and right from 80rpm, utilize drain filter 8c to remove the velveteen of washings.
Then, when the rotating speed from starting to increase swing roller 4 during through official hour T, control part 11a reduces the rotating speed of motor 6.
Afterwards, in the tumbling action of the washings of control part 11a in being stirred swing roller 4, start to the interior water supply of tank 3 and the running that stops circulating pump 30.In addition, in tumbling action, the direction of rotation of swing roller 4 can be both positive and negative rotation, can be also the rotation of fixed-direction.Thus, washings is peeled off by the internal perisporium 4c from swing roller 4, is stirred in the water of tank 3 and carries out rinsing accumulating.
During this period, when to the interior retaining of tank 3, by water level detecting section 10, water level h2 being detected, control part 11a controls feed water valve 7b and stops supplying water.While after stopping water supply, passing through official hour t2, control part 11a shuts down swing roller 4.In addition, in order to keep sufficient rinsing performance, official hour t2 is set as longer than official hour t1, this official hour t1 is the time that swing roller 4 is rotated during dehydration with high rotating speed in the middle of rinse step for the first time.Thus, supply water to stir and finish, thereby finish rinse step for the first time.Then, transfer to the i.e. rinse step for the second time of following step.
In rinse step for the second time, carry out successively the centre dewatering and supply water and stir each action, wherein, this centre dewatering is mainly dewatered, and rinsing is mainly carried out in this water supply stirring.
As shown in Figure 3, in the action of middle dewatering, control part 11a makes swing roller 4 rotate to fixed-direction.Direction of rotation when now, direction of rotation can stir action with the water supply in rinse step for the first time is identical also can be in contrast.
In addition, swing roller 4 is rotated to fixed-direction with the first rotating speed such as 80rpm etc. that makes washings be attached at the internal perisporium 4c of swing roller 4 under the state of draining.In addition, the rotating speed of swing roller 4, such as being that the rotating speed that 50rpm～120rpm etc. makes washings be attached at the internal perisporium 4c of swing roller 4 gets final product, is preferably for example rotating speed of the scope of 80rpm～100rpm.In addition, the rotating speed of swing roller 4 can not fixed, can be step by step or be increased to pro rata the rotating speed of regulation yet.
The rotation that starts to be fixed direction from swing roller 4, through after the time t3 as the first stipulated time, control part 11a controls draining valve 8b and starts to discharge the water in tank 3.Thus, the water level of the water in tank 3 descends gradually.Simultaneously, the signal of control part 11a based on from water level detecting section 10 makes the rotating speed of swing roller 4 for example be increased to the second rotating speed of 500rpm left and right.Now, the washings in swing roller 4 is rotated with the state of the internal perisporium 4c that is attached at swing roller 4.At this, as the time t3 of the first stipulated time, be until swing roller 4 is the time of fixed rotating speed on fixed-direction.
The first rotating speed of the swing roller 4 during in addition, by the middle dewatering of rinse step for the second time is made as than the low rotating speed of the second rotating speed during dehydration in the middle of rinse step for the first time.That is to say, by the rotating speed that reduces swing roller 4, prevent that the water of washings from all being removed.Its result, the weight of the washings by containing water and centrifugal force can not diminish, thus can maintain rinsing performance.
In addition, in the rotation of swing roller 4, control part 11a started the driving of circulating pump 30 before starting to discharge the water in tank 3.
That is to say, from swing roller 4, start to fixed-direction is rotated through after the time t4 as the second stipulated time, control part 11a starts the driving of circulating pump 30.
Then, by circulating pump 30 will from the interior water by circulation waterway 31 of tank 3, from jet 51 to swing roller, 4 interior washings spray.Now, washings absorbs the water spray, and the centrifugal force that utilizes the rotation by swing roller 4 to produce also dewatered, and washings carries out water suction and the dehydration of water repeatedly.
Thus, promote the replacing to the water of washings, the detergent ingredients in washings is dissolved in the water on every side that is present in washings.In addition, can remove efficiently in washings residual such as detergent ingredients such as foams.Its result, the detergent ingredients in washings tails off at short notice.
Afterwards, carry out draining, when by water level detecting section 10, predetermined water level h3 being detected, control part 11a stops the driving of circulating pump 30.In addition, predetermined water level h3 is the water level that circulating pump 30 does not have the degree that air sneaks into.The air that thus, can prevent circulating pump 30 is sneaked into and the water in tank 3 is circulated efficiently via recirculated water bleed pipe 32.
Then, from the High Rotation Speed dewatering step in the middle of swing roller 4 starts to carry out, through after official hour t5, control part 11a stops the rotation swing roller 4.Then, when the rotation of swing roller 4 stops, the release of middle dewatering, transfer to the action of the water supply stirring of ensuing rinse step for the second time.
In the action of supply water stirring, control part 11a starts the tumbling action that swing roller 4 is stirred opening feed water valve 7b in tank 3 retainings.
Then, when to the interior retaining of tank 3, by water level detecting section 10, water level h4 being detected, control part 11a controls feed water valve 7b and stops supplying water, and starts the driving of circulating pump 30 simultaneously.
Then, from stopping water supply, through after official hour t6, control part 11a shuts down swing roller 4 and circulating pump 30, thus the release of supplying water and stirring.Thus, rinse step finishes for the second time, transfers to the final dewatering of ensuing dehydration.
In the action of final dewatering, at first, control part 11a makes swing roller 4 be rotated with fixed-direction.Direction of rotation during action that in addition, direction of rotation can stir with the water supply in rinse step for the first time and for the second time is identical also can be in contrast.
In addition, swing roller 4 is rotated to fixed-direction with the rotating speed of the regulation such as 80rpm etc. that makes washings be attached at the internal perisporium 4c of swing roller 4 under the state of draining.In addition, the rotating speed of swing roller 4, such as being that the rotating speed that 50rpm～120rpm etc. makes washings be attached at the internal perisporium 4c of swing roller 4 gets final product, is preferably for example rotating speed of the scope of 80rpm～100rpm.In addition, the rotating speed of swing roller 4 can not fixed, can be step by step or be increased to pro rata the rotating speed of regulation yet.
Then, through after official hour t7, control part 11a controls draining valve 8b and starts to discharge the water in tank 3 the rotation that starts to be fixed direction from swing roller 4.Thus, the water level of the water in tank 3 descends gradually.Simultaneously, the signal of control part 11a based on from water level detecting section 10 makes the rotating speed of swing roller 4 for example be increased to the high speed rotating speed of 900rpm left and right.Now, the washings in swing roller 4 is rotated with the state of the internal perisporium 4c that is attached at swing roller 4.
In addition, at swing roller 4, be fixed in the rotary course of direction, control part 11a started the driving of circulating pump 30 before starting to discharge the water in tank 3.
That is to say, start to fixed-direction is rotated through official hour t8 from swing roller 4 after, control part 11a starts the driving of circulating pump 30.Then, by circulating pump 30, will from the washings in 51 pairs of swing rollers of jet 4, spray from the interior water by circulation waterway 31 of tank 3.Now, washings passes through sprayed water and absorbs water.And utilization is also dewatered by the centrifugal force of the rotation generation of swing roller 4, washings carries out water suction and the dehydration of water repeatedly.Thus, promote the replacing to the water of washings, the detergent ingredients in washings is dissolved in the water on every side that is present in washings.In addition, can effectively remove the detergent ingredients remained in washings.Its result, the detergent ingredients in washings tails off at short notice.
