The specific embodiment
Below, Yi Bian with reference to accompanying drawing embodiments of the present invention 1 ~ 3 are described on one side.In addition, be not to utilize embodiment to limit the present invention.
(embodiment 1)
Fig. 1 is the Sketch figure of the tumbling-box washing machine of embodiments of the present invention 1.As shown in Figure 1, be equipped with water jacket 2 in the inside of the shell 1 of washing machine integral body.Can be provided in by the state that rotating shaft is rotated the inboard of water jacket 2, this rotating shaft is downward-sloping from horizontal direction towards back side direction as the cylinder 3 of sink.Be connected with the motor 4 as drive division at the back side of cylinder 3, the rotation by motor 4 is rotated cylinder 3.In addition, be provided with a plurality of through holes at the outer peripheral face of cylinder 3, this cylinder 3 is also as sink, drench pit, dry slot and bring into play function.
Foot at water jacket 2 is connected with intake 5, and this intake 5 is connected with circulating path 12.The washings that are taken into from intake 5 are ejected into cylinder 3 via circulating path 12 from ejiction opening 11, circulate in washing machine thus.With the circulating pump 13 that is arranged in the circulating path 12 water is taken into circulating path 12.Like this, only controlled circulation pump 13 just can make washings circulate in circulating path 12.Therefore, can with the cleaning control of the common cleansing power of control irrespectively, the washings such as current that cylinder 3 rotation is produced circulate.
If contain the foreign matter such as fiber, hair of a lot of washings in the recirculated water of circulation time, then might stop up circulating pump 13, drainpipe 7.Therefore, the foreign matters such as fiber that filter 14 removes washings, hair are set between intake 5 and circulating pump 13.
Draining valve 6 is arranged between intake 5 and the circulating pump 13, is connected with the drainpipe 7 in the downstream that is positioned at draining valve 6.
Be provided with the level sensor 8 as water level detecting section at intake 5 places, this level sensor 8 is used for the water level of the water that is supplied to water jacket 2 and cylinder 3 is detected.Level sensor 8 is configured in the position that is immersed in immediately after the water supply in the water.Level sensor 8 will be for example by coming sensed water level for the distortion of film to the detection of barrier film (diaphragm) applied pressure.As the method for the distortion that detects barrier film, use variation, the deformation detector of static capacity.
Feed water inlet 9 is connected with water supply pipe, makes washings, washings be full of successively water jacket 2, cylinder 3 via feed water valve 10.
The action of the tumbling-box washing machine of embodiments of the present invention 1 then, is described with reference to Fig. 2.
Fig. 2 is the flow chart of cleaning control method of the tumbling-box washing machine of expression embodiments of the present invention 1.When washings being put into washing machine begin to wash, control part 16 carries out the cloth amount and detects, and detects the amount (step S1) of washings.
Carrying out the cloth amount by following main points detects.At first, motor 4 is rotated driving.At this moment, control part 16 temporarily is promoted to the rotating speed that makes washings be attached to this degree of internal perisporium of cylinder 3 with the rotating speed of cylinder 3, for example about 100rpm ~ 140rpm.After the rotary compasses of keeping cylinder 3 was fixed time, control part 16 stopped the energising to motor 4.Afterwards, cylinder 3 relies on inertia to be rotated, and motor 4 is rotated thus.At this moment, descend gradually owing to friction torque makes the rotating speed of cylinder 3, final cylinder 3 stops.About from stop to the energising of motor 4 until the time that cylinder 3 stops the rotation, should the time when the amount of washings is large long, should the time when the amount of washings is few short.The stop the rotation amount of the difference of required time and washings of this cylinder 3 is proportional, utilizes this point to detect the amount of washings.
Amount according to this washings decides basic output.For example, when the amount that is judged as washings was " lacking ", control part 16 was made as designated water level with " low " water level WL1.When the amount that is judged as washings for " in " time, control part 16 will " in " water level WL2 is made as designated water level.In addition, when the amount that is judged as washings was " many ", control part 16 was made as designated water level (step S2) with " height " water level WL3.
Then, control part 16 is opened feed water valve 10 (step S3), and external groove 2 and cylinder 3 supply water until reach designated water level (step S4).
Between delivery period, control part 16 controlled circulation pumps 13 make the washings of supplying with washing agent be circulated to water jacket 2 via circulating path 12 from ejiction opening 11, promote thus detergent dissolution in water.Be ejected into cylinder 3 when interior at recirculated water from ejiction opening 11, can absorb water at detergent dissolution clothing before water.Therefore, the speed setting with circulating pump 13 is low to following degree: it is interior but mobile along the leading section of cylinder 3 that recirculated water less is ejected into cylinder 3.
When confirming that output has reached designated water level (step S4 is "Yes"), control part 16 is closed feed water valve 10 (step S5).Then, enter the first stirring at low speed operation, in this operation, cylinder 3 is rotated with the low speed that washings is not adhered to this degree of internal face of cylinder 3.In the first stirring at low speed operation, begin agitator treating thing (step S6) while make cylinder 3 carry out low speed rotation.The rotating speed of cylinder 3 is following rotating speeds, that is, washings is lifted in cylinder 3, because Action of Gravity Field and falling from the top of cylinder 3, the kinetic energy when falling is applied to washings effectively.Thus, the rotating speed of the cylinder 3 of this moment is that centrifugal force can not make washings be attached to the rotating speed of this degree of internal face of cylinder 3.For example, the rotating speed of cylinder 3 also depends on the amount of washings, but is preferably below the 50rpm.The direction of rotation of cylinder 3 both can be same direction, also can carry out termly counter-rotating.
At this moment, control part 16 is circulated in the cylinder 3 from ejiction opening 11 via circulating path 12 by the washings that controlled circulation pump 13 fully dissolves washing agent.Thus, can promote that washings are penetrated in the washings.Therefore, preferably the rotating speed of circulating pump 13 is made as and reliably recirculated water is ejected in the cylinder 3 and is easy to make washings to be penetrated into rotating speed in the washings.
Fig. 3 is sensed water level and the poor figure of sensed water level in the matting of tumbling-box washing machine of expression embodiments of the present invention 1.As shown in Figure 3, make in the first stirring at low speed operation (step S6) of cylinder 3 low speed rotation after finish supplying water, washings constantly absorbs washings, and therefore the sensed water level as the output of level sensor 8 descends gradually.When washings absorbs washings fully, the vary stable of water level.And, the absolute value of the difference of the value of reading when the value of reading from level sensor 8 (output of level sensor 8) and last time for setting value below, for example the absolute value of one minute interpolation is 5mm when following, control part 16 is considered as absorbing water and reaches capacity.Like this, whether fully the variable quantity of the output by observing level sensor 8 does not rely on cloth matter and can judge washings suction.
In addition, can make with continuous operation once the operation of cylinder 3 High Rotation Speeds.In addition, also can be by intermittently repeatedly begin/stop the operation of the energising of motor 4 is made the operation of cylinder 3 High Rotation Speeds with the short time.Make cylinder 3 High Rotation Speeds make sometimes washing agent produce excessive foam.Therefore, in the situation that repeatedly operate, preferably intermittently carry out the operation of High Rotation Speed.
If before the first stirring at low speed operation middle water level is stable, transfer to the High Rotation Speed operation, then under the state that washings is not fully soaked by water, make cylinder 3 High Rotation Speeds.Therefore, it is large that the friction between cylinder 3 and the washings becomes, large to the damage change of washings.In addition, the washings that are mixed with washing agent are not penetrated in the washings fully, so the dirt of washings can not float by washings.Therefore, even the sink High Rotation Speed can not be peeled off the dirt of washings.In the present invention, by the washing agent that is made of surfactant being attached on the dirt material of clothes fiber carrying out the first stirring at low speed operation before the stable level.In the High Rotation Speed operation, remove near the clothes fiber washings by centrifugal force, therefore can efficiently the dirt material be removed from clothes fiber together with washings.And when cylinder 3 High Rotation Speed, if utilize circulating pump 13 that washings are sprayed to the washings in the cylinder 3, the washings that then also do not adhere to dirt are absorbed efficiently by the washings of transferring to dewater by the high-speed rotary of cylinder 3.Like this, by transferred the absorption of the dehydration that produces and the washings that spray by cylinder 3 high-speed rotaries, can promote the replacing of the washings that clothes fiber is contained.
As long as owing to twisting out the contained washings of washings, therefore making the time T of cylinder 3 High Rotation Speeds can be the shorter time, for example can be 30 seconds.
When the time T of High Rotation Speed operation during through 30 seconds (step S9 is "Yes"), control part 16 then implements to make again the second stirring at low speed operation (step S10) of low speed rotation of cylinder 3.With the first stirring at low speed operation similarly, in the second stirring at low speed operation, control part 16 starts circulating pump 13.The washings of water jacket 2 are circulated in the cylinder 3 from ejiction opening 11 via circulating path 12.At this moment, cylinder 3 is rotated with the rotating speed of following degree: washings is not adhered to the internal face of cylinder 3 but rolls on ground, rumble, cylinder 3 interior rumble.In addition, making circulating pump 13 runnings come from the action of ejiction opening 11 ejection washings can be the action of continuous operation, also can be the action of intermittent running.
By after the High Rotation Speed operation, also proceeding the second stirring at low speed operation, can utilize the chemical force of washing agent and follow the mechanical force of the low speed rotation of cylinder 3 again to peel off dirt material residual in the fiber.In the high situation of the concentration of the dirt material in interfibrous washings, worry that the dirt material adheres again on the fiber.But, be attached with the surfactant of washing agent and blamed to adhere again on the fiber by the fouling products that surfactant surrounds.Therefore, only adsorbing the surfactant that is not attached on the dirt material on the washings.Thus, the chemical property of washing agent is played a role to residual dirt.
Therefore the time of the second stirring at low speed operation be fixed as the stipulated time that does not rely on the cloth amount so long as the time that residual washing agent fully is penetrated in the washings gets final product.In embodiments of the present invention 1, the afore mentioned rules time is made as 5.5 minutes, if passed through the stipulated time (step S11 is "Yes"), then matting finishes.By like this, even computing, constant table also can be finished matting less, therefore can alleviate the burden of control part 16.
As mentioned above, after the water supply, carry out the operation (the first stirring at low speed operation) of low speed rotation until the stable output of level sensor 8, washings fully contains the washings that mixed washing agent and becomes the state that soaks into thus.So the dirt of washings adsorbs the surfactant of washing agent and is dissolved in the washings.Afterwards, by the operation (High Rotation Speed operation) that makes cylinder 3 High Rotation Speeds, will be present near the washings that are mixed with washing agent of washings and peel off with the dirt that is attached on the washing agent.By washing agent is penetrated in the residual dirt of washings again.
In addition, the illustrated control action of embodiment 1 can be so that possess the form of the program that the hardware resources such as telecommunications breath equipment, computer, server of CPU (perhaps microcomputer), RAM, ROM, stored record device, I/O etc. match and implement.If the form of program then by being recorded in the recording mediums such as disk, light medium, perhaps uses the communication lines such as internet to deliver letters, can make issue, renewal and the installation exercise thereof of new function become simple.
In addition, be not only tumbling-box washing machine, also can obtain identical effect as the drum-type washing drying machine that attaches functions/drying.
(embodiment 2)
The structure of the roller washing machine that the Sketch of the tumbling-box washing machine of embodiments of the present invention 2 and embodiments of the present invention 1 are illustrated is identical.About the detailed description of structure, quote the explanation of embodiment 1.In embodiments of the present invention 2, be made as and when level sensor 8 is output as the first setting, carry out above-mentioned High Rotation Speed operation.
Fig. 4 is the flow chart of cleaning control method of the tumbling-box washing machine of expression embodiments of the present invention 2.Fig. 5 is the figure of the relation of the sensed water level of tumbling-box washing machine of expression embodiments of the present invention 2 and scavenging period.
About water supply operation (step S1A), identical with embodiments of the present invention 1.
When entering matting, carry out the first stirring at low speed operation (step S6), in this operation, cylinder 3 is rotated with the low speed that washings is not adhered to this degree of internal face of cylinder 3, read termly the output (step S20) of level sensor 8.If the sensed water level as the output of level sensor 8 becomes the first setting, (step S20 is "Yes") below for example 20cm, then control part 16 is considered as washings and has fully absorbed washings.Afterwards, control part 16 control motor 4 make cylinder 3 High Rotation Speeds, transfer to High Rotation Speed operation (step S8).
If the sensed water level as the output of level sensor 8 does not become (step S20 is "No") below the 20cm, then also surpass setting-up time (for example 15 minutes) during (step S21 is "No"), proceed the first stirring at low speed operation.
Do not become in the situation that state below the 20cm passed through setting-up time (for example 15 minutes) (step S21 is "Yes") in the sensed water level as the output of level sensor 8, directly finish matting.
When the time T of High Rotation Speed operation during through 30 seconds (step S9 is "Yes"), as enforcement mode 1, while control part 16 makes cylinder 3 low speed rotation stir (the second stirring at low speed operation) (step S10) again.In the second stirring at low speed operation, when through the stipulated time (step S11 is "Yes"), finish matting.
As mentioned above, after the water supply, if the output of level sensor 8 becomes below the setting, then make the operation (High Rotation Speed operation) of cylinder 3 High Rotation Speeds, can near the cleaning solution that is mixed with washing agent the washings and the dirt that is attached on the washing agent be peeled off in the stage that washings fully are penetrated in the washings thus.Thus, washing agent is penetrated in the residual dirt of washings again.
In addition, in the present embodiment, the water level of the regulation when transferring to the High Rotation Speed operation is made as fixed value, but the amount that also can be set as with washings is worth accordingly.For example, the predetermined water level as minimum the when weight that can preset washings is detected as zero, being set as 1 kilogram of the every increase of laundry amounts increases 10mm with predetermined water level.By like this, can make clothing be in the state that fully is dipped in the washings.
(embodiment 3)
The structure of the Sketch of the tumbling-box washing machine of embodiments of the present invention 3 and embodiments of the present invention 1 and 2 illustrated roller washing machines is identical.About the detailed description of structure, quote the explanation of embodiment 1 and 2.In embodiments of the present invention 3, in above-mentioned stirring at low speed operation, when level sensor 8 is output as the second setting when following, control part 16 carries out supply of groundwater.
Fig. 6 is the flow chart of cleaning control method of the tumbling-box washing machine of expression embodiments of the present invention 3.Fig. 7 is the figure of the relation of the sensed water level of tumbling-box washing machine of expression embodiments of the present invention 3 and scavenging period.
Describe with reference to Fig. 6 and Fig. 7 pair of difference with embodiment 2.There is following situation in difference according to the cloth matter of washings: although washings are supplied to the water level of regulation, after because the washings suction causes the washings deficiency in the cylinder 3.Therefore, when sensed water level at the appointed time is reduced to the second setting, when for example 10cm is following, carries out supply of groundwater and come again water level raising, not enough to avoid cleaning solution.
In Fig. 6, the sensed water level as the output of level sensor 8 be (step S20 is "Yes") below the 20cm and entering the water supply operation after elapsed time do not reach stipulated time A during (step S30 is "No") and sensed water level be that control part 16 carries out supply of groundwater (step S32) in the situation below the 10cm (step S31 is "Yes").Afterwards, control part 16 is proceeded the first stirring at low speed operation (step S6).On the other hand, if keep below the 20cm and do not become below the 10cm and through stipulated time A (step S30 is "Yes"), then transfer to High Rotation Speed operation (step S8) as the sensed water level of the output of level sensor 8.At this, as stipulated time A, for example can be made as about two minutes.
As mentioned above, after water supply until through stipulated time A, if the output of level sensor 8 becomes below the setting, then carry out supply of groundwater, even in the high situation that water level is descended of water imbibition owing to washings, cleaning performance is not reduced easily thus.In addition, can reduce the damage that under the insufficient state of washings, owing to rubbing washings is caused.
As described above, tumbling-box washing machine of the present invention possesses: sink, and it is accommodated washings and is rotated; Water jacket, it accommodates sink; Drive division, it drives sink; Water level detecting section, the water level in its external groove detects; And control part, its basis is judged water level from the output of water level detecting section, and carries out the control of drive division.Control part comprises the matting of stirring at low speed operation and High Rotation Speed operation, wherein, in this stirring at low speed operation, sink is rotated with the low speed that washings is not adhered to this degree of internal face of sink, in this High Rotation Speed operation, make the sink High Rotation Speed so that washings becomes the state of the internal face that is attached to sink.When stirring at low speed operation middle water level test section is output as rated condition, control part carries out the High Rotation Speed operation.
According to this structure, can under the state that dirt is fully floated from washings, peel off dirt, thereby clean quickly.
