The high speed rotating pattern
According to a further aspect of the present invention, this washing machine 5 (referring to Fig. 1) provides the operation of high speed rotating pattern in due course in the drying cycle of washing machine 5 or mode process.Especially, the motor 26 of washing machine 5 is with two speed operation, promptly normal or first speed and at a high speed or second speed.Because motor 26 is connected to container 32, make motor 26 rotary containers 32, these motor 26 these containers of rotation arrive the upper limit of first speed, and the upper limit that arrives second speed.Should be known in this term " arrival " and, rotate with identical or maximum first or the second speed of motor 26 with two speed rotations according to known applying of firm power but various factors may prevent container 32 even be used to indicate motor 26.In stationary state and/or in rotary course, there is various factors can be measured as the parameter of container 32.
This first speed is corresponding to the conventional Rotary drying cyclic pattern of washing machine 5, and second speed is corresponding to current high speed rotating pattern, and wherein container 32 is to rotate greater than the speed of first speed.A kind of typical first speed is approximately 600RPM.In order to prevent that processor or controller detect various parameters motor 26 and/or washing machine 5 when container 32 rotates with first speed owing to damaging washing machine 5 with overweight, the unbalanced load of second speed rotation.If the parameter that is detected is in acceptable parameter level or scope, then processor 60 makes motor 26 with second speed (higher speed) rotary container 32, thus cause than first speed (conventional speeds) more the clothing from container 32 get rid of moisture.The second speed of a signal or high speed are approximately 800-850RPM, but may be approximately about 700RPM according to the type of washing machine.
Referring to Figure 14, shown in it according to the block scheme that the washing machine 5 of current high speed rotating features/functionality is provided of the present invention.This washing machine 5 is shown having the container 32 of the clothing that acceptance will clean.This container 32 is suitable for rotation and arrives maximum first speed and arrive maximum second speed, and this second speed is greater than first speed.Container 32 is connected to motor 26, and it rotates this container with first and second speed.
Should know that high speed rotating of the present invention aspect is relevant with the drying cycle or the pattern of washing machine 5.Container 32 is generally swung in cleaning model or periodic process, makes container 32 rotate in one direction in the consecutive periods of short time then in another direction rotation (clockwise and inverse clock).But, when washing machine 5 is in drying mode or in the cycle time (, this washing machine attempts removing excessive water from clothing), container 32 rotates (clockwise or inverse clock) by motor 26 on single sense of rotation.This motor 26 in normal or typical drying mode or periodic process with the first speed rotary container 32.Suppose that this washing machine 5 is in drying mode or in the cycle, is used for the purpose of current described high speed rotating.
Motor 26 is under the control of processor 60.This processor 60 utilizes the programmed instruction that is stored in the storer 116 to carry out current high speed rotating function.Washing machine 5 further comprises a container parameters detecting device 180.This container parameters detecting device 180 is connected to container 32 and/or washing machine 5 self by circuit 181, or communicates with (in this case, this container parameters detecting device is as a washing machine detecting device).This container parameters detecting device 180 receives or detects about the overall supplemental characteristic of container 32 and/or washing machine 5, produce the signal of an expression supplemental characteristic that detects and/or respond to, and the container parameters data-signal that institute is detected and/or responds to is forwarded to processor 60.In the operating process of washing machine 5, this container parameters detecting device 180 is provided to processor 60 to the container parameters data-signal, but is not used or in the operating cycle process except drying cycle, can also provides related data when washing machine 5.This processor 60 utilizes the container parameters data-signal to determine the mode of operation of the overall and/or container 32 of washing machine 5.This container parameters detector data signal indication is based on the numerical value or the level of discrete and/or continuous supplemental characteristic.
Motor 26 was worked in the process in drying cycle, with the first speed rotary container 32, arrived the first specific speed.At this moment, processor 60 receptions are from the container parameters data-signal of container parameters detecting device 180.If this parameter data signal, then makes second speed or the high speed rotating of this motor 26 to be higher than first speed less than predetermined threshold or level or in a predetermined threshold range.As an above-mentioned example, first speed of the second speed of this container 32 or high speed container 32 is big by 25%.Therefore, container 32 is by with second speed or high speed rotating.This parameter data signal is monitored, to determine whether this parameter surpasses intended threshold level or outside this threshold range, so that motor 26 turns back to first speed, therefore the rotating speed of container 32 to be reduced to the maximal value of first speed.In the drying cycle of washing machine 5 process, this can suitably be repeated.
In Figure 15, shown in it according to the more detailed block scheme of the washing machine 5 of principle shown here.In Figure 15, washing machine 5 comprises and processor 60 control of communication circuitry/logic 182, and the two speed motor 26a that communicate by letter with control circuit/logical one 82.This two speed motor 26a rotates with different speed with second at a high speed according to first speed.Then, container 32 can be rotated by two speed motor 26a, arrives the maximum (top) speed of first and second speed.The maximum (top) speed of this container 32 is by the various parameters of this such container of the maximum (top) speed of motor 26a and for example charge capacity and load balance or the restriction of condition.This motor 26a receives the signal from control circuit/logical one 82, it receives the control signal of from processor 60, exciting electric 26a particularly correspondingly places first or second speed to motor 26a, and perhaps the suitable coil of the motor 26a of two kinds of speed is responsible in excitation.Once more, these storer 116 storages suitably are provided to the programmed instruction of processor 276.This washing machine 5 comprises the container parameters detecting device 180 of communicating by letter with container 32 and/or washing machine 5.The data that this container parameters detecting device 180 obtains about the various conditioned disjunction parameters of container 32 and/or washing machine 5 are particularly in the drying cycle of washing machine 5 process.This condition/supplemental characteristic is forwarded to processor 60 by the programmed instruction that is stored in the storer 116, analyzing this condition/supplemental characteristic, and suitably output is provided to various miscellaneous parts and/or circuitry/logic.Determine whether the container condition is fit to rotate this container 32 with high rotating speed.
Referring to Figure 16, the block scheme of washing machine 5, the particularly block scheme of control circuit/logical one 82 are shown in further detail wherein.Control circuit/logical one 82 comprises first speed switch or commutation circuit/logical one 84 and second speed switch or commutation circuit/logical one 86, and it is respectively under the control of processor 60.This first speed switch 184 makes two speed motor 26a with first speed operation.This second speed switch 186 makes two speed motor 26a with second speed work, and wherein second speed is greater than first speed.Especially, this second speed is the high rotation speed that is used for container 32.This washing machine 5 also comprises door switch 28, and it cuts off motor 26a when the lid of washing machine or door are opened.
Door switch 28 is communicated with (referring to Fig. 1) with the lid 34 of washing machine 5, makes that lid 34 must be closed before motor 26a work.When work 34 closures, this switch makes motor 26a work.When lid 34 was opened, this switch prevented motor 26a work.Switch 34 Chang Kai or normally closed whether no matter.In this manner, door switch 34 provides a kind of release mechanism.In addition, the state of this door switch 34 is monitored by processor 60, when lid 34 is opened, makes that other functions of washing machine 5 and/or feature must temporarily be stopped at least, can restart when lid 34 is closed then.
According to parameter that will be monitored or state, container parameters detecting device 180 can adopt several forms.In one form, the vibration of this container 32 or rock and to be monitored.In another form, the rotational speed of this container 32 or speed can be monitored.Charge capacity (weight) and/or responsible distribution also can be considered.Certainly, other parameters of container 32 or condition can be detected, monitor or measure.Should know the condition of container parameters detecting device 180 expression detection, supervision and/or measuring vessel 32 or washing machines 5 and/or one or more forms of parameter.Similarly, should be known in that this term " parameter " also comprises condition, state, pattern, characteristic, mode or the like.
This container 32 (and/or washing machine 5) is monitored by one or more above-mentioned forms, and is uneven to detect in drying cycle (rotation) process, especially or at first in first speed.As the result that the bad laundry load in container 32 distributes, the imbalance of the container 32 relevant with the intermediate vertical axle of container 32 may cause the unsuitable stress and strain in this system.Owing to quite high speed or all number rotary containers 32 of per minute, attempting or obtaining higher rate (high speed rotating) to monitor that before this container is suitable drying cycle.If this container of rotation then will obtain the high speed rotating pattern, otherwise this motor will remain on first speed in an acceptable parameter threshold scope or under parameter threshold.And, if the high speed rotating failure is suitable in the first speed watch-keeping then, to determine whether and can obtain high speed rotating in remaining drying time, and watch-keeping is to detect whether enter non-equilibrium state after realizing the high speed rotating pattern, and this motor will be got back to first speed.Should in rotary course, monitor the non-equilibrium state of container 32, to avoid mechanical problem.
Can utilize vibration transducer or place on the container 32 and/or the vibration of sensor monitoring on every side.The vibration data that this processor 60 monitors from vibration transducer.Especially, in normal drying process process, monitor this vibration data under the control of the programmed instruction of this processor 60 in being stored in storer 116.If this vibration data shows this vibration and is under a threshold value vibrating numerical or the level that perhaps in a threshold range, then processor 60 will send to second speed switch 186 to a pumping signal.This pumping signal will make second speed switch 186 that two speed motor 26a are placed second speed (high speed rotating), make container 32 that rotation is reached second speed.In the high speed rotating mode process, processor 60 continues to monitor the vibration data from vibration transducer.
Load/equilibrium state from this container 32 of vibration data ordinary representation of this vibration transducer.Specifically, if the clothing in container 32 in first rate process by balance well, then in first speed rotation of container 32, will produce fewer vibrations or do not vibrate.But, if the balance well not in the first speed rotary course of container 32 of the clothing in container 32 then exists than more manying balanced load to have greatly and vibrate.Before processor 60 excitation second speed switches 186 make that motor 26a is with high rotating speed rotary container 32, the degree of this vibration or level must can be accepted (promptly, be in or be lower than a threshold value level of vibration, perhaps a threshold value level of vibration scope is interior) (in addition, if extent of vibration is unacceptable, then processor 60 will not encourage second speed switch 186, and it makes motor 26a enter the high speed rotating pattern).
The rotational speed of container 32 or speed can also be monitored, detect or measure from rotating shaft of this container self, container 32 or the like.This can realize by a hall effect sensor and magnet, light-beam transmitter/detecting device, shaft-position encoder (shaft encoder) or the like.In the situation that the container rotating speed detects, under perfect condition or situation, this container 32 only can rotate with maximum motor speed.Velocity deviation in downward direction (less than maximal value) rotating speed is represented laod unbalance.But, in general, container can be not ideally first or second speed obtain the maximum (top) speed or the speed of motor.Even, also can be slightly less than maximal rate for the laundry load of " well " balance.In other words, the rotating speed of this container is generally slower than desirable motor speed.Therefore, the rotating speed of container 32 will be monitored, detect or measure, with the rotating speed of determining this container or whether speed is higher than a threshold value tachometer value or in an acceptable range of speeds.If the rotating speed of container 32 is on this threshold speed value, perhaps in this acceptable threshold velocity scope, then processor 60 will make second speed switch 186 start, and cause motor 26a to enter high speed rotating pattern (second speed).And parametric detector 180 will provide watch-keeping, detection and/or the measurement to rotating speed, should turn back to first speed to determine whether all normal or these motors.
As the example of the rotating speed that uses this container as this supplemental characteristic, first speed can be approximately 600RPM, and second speed can be 800RPM.The threshold level that this second speed starts can be not less than 80% (that is, this container 32 must rotate) of first speed between the 80%-100% of first speed.If container 32 rotates in the speed less than 80%, then will not use high speed rotating.Similarly, when washing machine 5 is in the high speed rotating pattern (in second speed), the rotating speed of this container may be not less than 80% of second speed, to keep the high speed rotating pattern.Container speed will cause washing machine to turn back to first speed less than 80% of second speed.
In Figure 17 and 18, has the circuit diagram of a part of an embodiment of the washing machine of high speed rotating characteristic of the present invention shown in it.Two speed motor 26a comprise an actuating coil 194, and itself and centrifugal switch 192 are in series.This actuating coil 194 and centrifugal switch 192 are connected between terminals P 10 and the P12.This terminals P 10 and P12 are connected to each relay 196 and 197, perhaps communicate with.This relay 196 and 198 is suitable for actuating coil 194 and centrifugal switch 192 are connected to line electricity (by the door switch 28 of closure) and neutral point.This relay 192 encourages with the relevant control/regulating circuit/logic of the enabling signal that receives from processor 60 by transistor Q10 (electronic switch) with 194.The control signal of from processor 60 provides the excitation of relay 196 and 198 by transistor Q10.When by transistor Q8 (electronic switch) with relevant control/regulating circuit/logic encouraged when a main power relay 200 is coupled to power lead 202 to the line electricity from door switch 28, this actuating coil 194 is energized.When motor 26a arrives travelling speed (being less than or equal to first motor speed), this centrifugal switch 192 makes actuating coil 194 and motor 26a open a way.
Meanwhile, main relay 200 is provided to actuating coil 194 to line electricity, and line electricity also is provided to one of first main coil 188 or second main coil 190.By selecting which coil to receive this line electricity with relay 204 controls that relevant control/regulating circuit/logic receives a pumping signal through transistor Q11 (electronic switch).Should be known in that each commutation circuit/repeater of Figure 17 receives the pumping signal of from processor 60.This first main coil 188 is suitable for allowing motor 26a to obtain first speed, and this second coil 190 is suitable for allowing motor 26a to obtain second speed.According to principle of the present invention, this second speed is greater than first speed and be called as high rotating speed.Therefore, main relay 200 operation circuit electricity are applied to first or second coil 188 or 190 by door switch 28.
This door switch 28 is coupled to line electricity in a circuit side or terminal, and another circuit side or terminal are coupled to terminals P 6.This terminals P 6 communicates with processor 60 by monitoring wire or conductor 202.This door switch 28 is with respect to the lid 34 of washing machine and be positioned (referring to Fig. 1), make door switch 28 be provided to processor 60 to a signal, whether thereby processor 60 can monitor door switch 28 (that is, the door or the lid of equipment) opens or closes (corresponding to the state of the lid of washing machine).This monitoring wire 202 is also communicated by letter with main relay 200.In this manner, even main relay 200 is in conducting state (line electricity is provided to first or second motor coil 188,190), (door or the lid of this equipment are opened) is cut off (that is, line electricity will flow through repeater 616) to the power of motor 26a when door switch 28 is opened.This provides the switch of a safety to cut off the power supply of motor 26a.
Referring to Figure 19, at the process flow diagram of a schematic operation mode of characteristic of this high speed rotating this illustrate or function, it is represented by 210 generally.In step 212, this washing machine is placed in or arrives cloth drying cycle, stage or pattern.In step 214, this motor or dynamic power generator are activated into first speed, so that the washing container of this washing machine rotates to first speed.Rotate in the process of first speed at this washing container, obtain the container parameters data, step 216.These container parameters data can obtain from the vibration transducer of location, to obtain from this container and/or the overall vibration data of washing machine; Obtain from the revolution detector of location, to obtain rotary speed data from this container or part container or container rotating shaft; Perhaps obtain from other detecting devices of detecting or measuring other container parameters data, transducer or the like.
In step 218, the container parameters data that obtained are analyzed.Specifically, analyze the container parameters data that obtained under the control of the programmed instruction (software) of this processor in being stored in this storer.This processor is analyzed this container parameters data, to determine this container whether uneven (that is, the bad distribution of this laundry load causes imbalance).More specifically, in step 220, according to special parameter, whether these container parameters data are analyzed is lower than predetermined parameter threshold level or numerical value with specific parameter or a plurality of parameter of determining this washing machine/container, and in a specific parameter threshold scope, perhaps on predetermined parameter threshold level or numerical value.This predetermined threshold or level are selected, if make higher speed be used to the rotation of this container, then seldom because the result of second speed causes damage.
In step 220, if this container parameters outside suitable or predetermined threshold value or scope, then this motor 26 is maintained at first speed (so this container also keeps first speed), and this flow process turns back to step 216.Also check whether finish maybe will finish this drying cycle, if for being then this flow process end, step 222.But, if this container parameters is at this suitably or in predetermined threshold value or the scope, then this motor is excited to the second high rotating speed, and this container also is in this speed, step 224.Then, continue to monitor step 226.Turn back to step 220. this process cycle
Contact brush assembly and pattern control
This mode switch 378 has two positions, and it determines two operator schemes of main controller module 300, that is, and and user's cycle preference pattern and cycleoperation pattern.This user's cycle selector is rotated by this user, with a specific operation cycle (that is selected equipment periodic) of selecting this washing machine 5.Referring to Figure 53, in the operating cycle of various signals shown in it, for example be printed on " non-ironing ", " high-count fabric ", " prewashing ", " cotton " and " rinsing and rotation " on the overlayer 388 adjacent with LED.Certainly, can provide other and/or different cycles as required.In the rotary course of user's cycle selector, according to the sense of rotation and the rotational speed of user's cycle selector, each LED307 (represented by triangle) is alternately lighted.According to the sense of rotation and the speed of rotation of user's cycle selector, this processor 60 produces the position signalling that is used for each LED307.This position signalling is used to light and extinguish suitable LED.When user's cycle selector was rotated, suitable or next LED was lighted, and the previous LED that lights is extinguished.Required cycle or the position in one-period in case selected (that is, suitable LED is lighted), then by this control handle is pressed down towards this overlayer 388, this user places the cycleoperation pattern to washing machine 5.
Referring to Figure 47 and 50, the translation of this user's cycle selector when main controller module 300 is in user's cycle preference pattern and the generation of rotation and/or position signalling will be discussed below.This contact brush 336 and circuit diagram assembly 338 are cooperated in the rotary course of load bearing component 334 (it is the part of user's cycle selector assembly), when user's cycle preference pattern being shown at this mode switch 378, select user's cycle signal and/or position signalling (be used to light suitable LED and show this cycle and the ad-hoc location state in this cycle) to offer processor 60 to this processor
This contact brush 336 comprises three finger pieces 380,382 and 284.This inboard finger piece 380 is voltage source terminal that receive from the voltage of circuit diagram assembly 338.This centre finger piece 382 is first state terminals arbitrarily, and it is sent to processor 60 to voltage from inboard finger piece 380 in due course.This outside finger piece 384 is second state terminals arbitrarily, and it is sent to processor 60 to voltage from inboard finger piece 380 in due course.
This circuit diagram assembly 338 comprises a Voltage trace or conductor 390, the terminal 396 that its termination is connected with a voltage source.This circuit diagram assembly 338 also comprises the first state trace or the conductor 392 of pattern in a zigzag, the terminal 398 that its termination is connected with processor 60.This circuit diagram assembly 338 further comprises the second state trace or the conductor 394 of pattern in a zigzag, the terminal 400 that its termination is connected with processor 60.This processor 60 monitors first and second traces 392,394 by terminal 398,400, with the signal that obtains to be provided by contact brush 336.
When 332 rotations of contact brush assembly, this brake arm 390 is provided to finger piece 380 to continuous voltage.In the process of contact brush assembly 332 rotation, middle finger piece 382 rotate according to a circle, because this zigzag pattern, it is alternately contacted with the first state trace 392 and disconnects.Meanwhile, this outside finger piece 384 rotates according to a circle, because this pattern in a zigzag, it is alternately contacted with the second state trace 394 and disconnects.Can from Figure 50, find out, this first and second trace 392,394 zigzag pattern provides as lower area: in contact brush assembly 332 rotary courses, finger piece 382 is the zone that is provided to processor 60 from the voltage (signal) of inboard finger piece 380 only, only outside finger piece 384 is provided to a voltage (signal) zone of this processor from inboard finger piece 380, middle or outside finger piece 382,384 are not provided to a voltage (signal) zone of this processor, and this centre or outside finger piece 382,384 all are provided to a voltage (signal) zone of this processor.
A voltage can be considered to logical one, and does not have voltage can be considered to logical zero.Therefore, contact brush assembly 332 provides " 00 " state (middle finger piece 382 and outside finger piece 384 do not transmit a voltage), (middle finger piece 382 does not transmit a voltage to " 01 " state, but outside finger piece 384 transmits a voltage), (middle finger piece 382 transmits a voltage to " 10 " state, but outside finger piece 384 does not transmit a voltage), and " 11 " state (middle and outside finger piece 382,384 all transmits a voltage).This one of four states did not still repeat before all one of four states have been used not necessarily according to any specific order.Therefore, this processor 60 detects this state change (by counting or the like method).And sense of rotation can be by learning that state changes and its order is determined.Therefore, this processor can produce the position signalling that is used to light LED, follows the tracks of the position of user's cycle selector, and learns the operating cycle that the user selects.Certainly, should know that above-mentioned variation can be used, for example the number of finger piece, trace patterns or the like.
In this cycleoperation pattern, these 5 these specific selected cycles of operation of washing machine, and the not influence of this user's cycle selector are because this mode switch 378 is in release conditions at this moment.But the LED307 in the selected cycle that this is specific sequentially alternately lights, with the display operation cycle progression.This processor 60 is provided to the cycle progression signal transistor Q1, Q2, Q3, Q4 and the Q5 (Figure 23 and 24) of suitable LED group 270,272,274,276 and 278 (corresponding to the cycle of user's selection), to encourage this group LED307, and suitably be provided to driver/buffer 238, to light the specific LED307 of LED group.
As an example, in Figure 54, suppose that the cotton operating cycle is user-selected by this in user's preference pattern process.When this user rotates user's knob 318, represent that by lighting (LED307's) startup LED401 this cycle is activated.In the next stage in this cycle, determined and performed that by the programmed instruction in storer 116 this startup LED401 extinguishes, and next LED402 lights by processor 60.In the next stage in this cycle, this LED402 extinguishes, and next LED403 lights.At last, when this " cotton " end cycle, last LED404 lights and previous LED403 extinguishes.In this manner, indication cycle's process.This processor 60 suitably provides the cycle progression signal.
Figure 22 illustrates the circuit diagram that is used for the circuit diagram assembly.This terminal 396 receives the voltage that is used for conductive trace 390.This first state output end 398 that is used for the first state conductive trace 392 is connected to processor 60 as an output.Similarly, second state output end 400 that is used for the second state conductive trace 394 is connected to processor 60, as its input end.
