Describe the preferred embodiment of the present invention below with reference to the accompanying drawings in detail.
As shown in Figure 3, in shell 40, be provided with a cylindrical bucket 42 that supports by a plurality of cantilevers 48.In bucket 42, columniform wash bucket 44 rotatably is installed, form a plurality of holes on it.An impeller 46 is installed in the inner bottom part of wash bucket 44, can rotate forward or backwards, thereby produce current.
The driving mechanism that drives wash bucket 44 and impeller 46 be located at wash bucket 44 below.Driving mechanism comprises a motor 62 that produces revolving force; A transmission device 64, selectively or simultaneously the revolving force with motor is transferred to impeller 46 and wash bucket 44.A top cover 50 is installed in the top of the opening of shell 40.A door 52 is located on the top cover 50, opens or closes the open top of shell 40.
Uneven checkout gear is located in the shell 40, when laundry or dehydration, detects any unbalance dynamic of wash bucket 44 and the on off state of door 52.
Shown in Fig. 3 and 4, uneven checkout gear comprises: a magnetic generating means 54 is installed to the top of wash bucket 42; A magnetic detection device 56 vertically is arranged on the magnetic generating means 54, separates predetermined distance towards magnetic generating means 54; With a lever 60, be assembled on the hinge axis 58 of door 52, and hold magnetic detection device 56 therein, make along with the switch motion of door 52, swing magnetic detection device.
Best, magnetic generating means 54 is magnets, and magnetic detection device 56 is reed switches.
In addition, replace reed switch as magnetic detection device 56, also can obtain uneven checkout gear of the present invention with a Hall element 56.Different is for Hall element and reed switch, and Hall element converts the magnetic intensity that detects to voltage strength, and reed switch only is to open or close according to the magnetic intensity that detects.Therefore, when the magnetic detection device, what the program of processing signals and definite washing machine work should be when adopting reed switch is different at Hall element.But according to the relevant work characteristic of reed switch and Hall element, this difference is not very big.Therefore, use these two any the time, all can obtain uneven checkout gear of the present invention.
And best, lever 60 is to be made by magnetic shielding material, if make lever 60 or bucket 42 swings surpass given angle, the magnetic force of magnet 54 does not reach reed switch 56.
Shown in the control block diagram of Fig. 5 washing machine of the present invention, control circuit comprises: a controller 70, it is the balance detecting device received signal never, determine whether door 52 is opened or whether wash bucket 44 rotates in non-equilibrium state, and send control signal according to definite result, the operation of control washing machine; A signal input apparatus 72 will be delivered to controller 70 by reed switch 56 and the signal that magnet 54 interacts generation; A motor-driven part 74 is controlled the driving of motor 62 according to the control signal of controller 70; A door drive part 76, the switch of operated door 52 automatically; A display 78; A buzzer 80; Feed water valve 82 and draining valve 84 according to the control signal work of controller 70; A level detection part 86 detects the laundry water liquid level in the bucket 42; A key input part 88, the user can set program for washing; With a weight detecting part 90, detect clothes weight.
One end of signal input apparatus 72 connects an end of reed switch 56, and the other end is connected to controller 70, makes it convert the work of reed switch 56 to the signal of telecommunication, and delivers to controller 70.Reed switch 56 does not connect the other end of signal input apparatus 72, and connects ground G.
If reed switch 56 is connected by the magnetic force of magnet 54, the voltage signal electric current that signal input apparatus 72 makes DC power supply (Vcc) supply, can flow to ground (G) by reed switch 56, and therefore, send 0 volt (hereinafter claiming " low " signal) " low " to controller 70 and press signal.On the other hand, if reed switch 56 disconnects on the magnetic force of magnet 54, it produces and sends to controller 70 " height " pressure signal (calling " height " signal in the following text) of 5 volts of dc voltages of DC power supply supply.
Work referring now to description of drawings washing machine of the present invention.
At first, if wash bucket 44 is owing to the non-equilibrium state that is non-uniformly distributed in of washing clothes is rotated when laundry or dehydration, wash bucket 44 bumps on the inwall of bucket 42, then, because the irregular vibration of bucket, be fixed to bucket 42 tops and be moved and become big with the distance of reed switch 56 towards the magnet 54 of reed switch 56.Along with the motion of magnet 54, if the magnetic force of 54 pairs of reed switches 56 of magnet makes the critical value of reed switch action little than one, reed switch 56 disconnects.
Best, shown in Fig. 6 and 7, if magnet 54 swings to given angle (θ 1) from the position of aiming at reed switch 56, because the magnetic force of magnet 54 no longer reaches the reed switch 56 in the lever 60 of magnetic shielding material, no matter the distance that magnet 54 and reed switch are 56 how, reed switch 56 disconnects.Therefore, regardless of the swaying direction of bucket 42, if swing surpasses given angle (θ 1), reed switch disconnects, thereby detects the imbalance of wash bucket 44.
When reed switch 56 disconnects as described above, 5 volts of voltage signals that apply from DC power supply (Vcc) are sent to controller 70.Then, controller 70 is considered as abnormal signal to 5 volts of voltage signals, with duration and predetermined reference value comparison of described input signal, then, determines whether wash bucket 44 rotates in non-equilibrium state.
On the other hand, if reed switch 56 is connected,, send " low " signal of 0 volt rather than 5 volts to controller 70 because the DC electric current that comes from DC power supply (Vcc) flows to ground (G) by reed switch 56.
If reed switch 56 is because disconnection is connected in the unbalance dynamic of wash bucket 44 repeatedly, " height " signal and " low " signal of producing when reed switch 56 disconnects and connects are alternately delivered to controller 70 respectively.
Then, the duration of the abnormal signal of input is in first scope time, i.e. 24-450 millisecond, and controller 70 determines whether abnormal signals are transmitted more than pre-determined number.Best, design like this, if the abnormal signal of first term of reference is transmitted more than three times, controller 70 determines that wash bucket 44 rotates in non-equilibrium state.Figure 10 illustrates when wash bucket 44 uneven rotations, never the waveform of the voltage signal of balance detecting device generation.If the duration of input signal is less than 24 milliseconds, if or " height " signal is sent to controller 70 only once or twice, controller 70 determines that input signals only are that noise or " height " signal are only represented can be by that the bascule (not shown) is handled slight and of short duration non-equilibrium state.
In addition, as shown in Figure 8, if door 52 is opened when washing machine is worked, reed switch 56 is with hinge axis 58 swings.Describe such motion below in detail.
If door 52 is opened, the lever 60 that is contained on the hinge axis 58 of door 52 is swung in the clockwise direction, and reed switch 56 is retreated from magnet 54.When outside the magnetic force scope that is positioned at magnet 54, reed switch 56 disconnects, as shown in Figure 9, if reed switch 60 is along with lever 60, swing greater than predetermined angle (θ 2) from the vertical line that connects reed switch 56 and magnet 54, the magnetic force that magnet 54 produces is the hole 61 by forming in the lever 60 no longer, thereby reed switch 56 is disconnected.
The same manner when detecting the uneven rotation of wash bucket, if reed switch 56 with the disconnection of opening of door 52, controller 70 is determined 52 opens according to the duration of " height " signal (5 volts) that receives.Preferably as shown in figure 11, when surpassed 450 milliseconds " height " signal duration, controller 70 definite doors were opened.
When determining that door 52 opens, or wash bucket 44 is when non-equilibrium state is rotated, and controller 70 makes the stop the rotation work of motor 62 of wash bucket 44 of motor-driven part 74.When the work of motor 62 stopped, controller 70 was notified the user by display 78 and buzzer 80.
If the work of motor 62 is supplied with a certain amount of water because the imbalance rotation of wash bucket 44 stops, and feed water valve 82 controlled devices 70 are opened to bucket 42, impeller 46 rotates preset times then, thereby the uneven distribution of washing clothes is disappeared.Then, controller 70 is opened draining valve 84, discharges the water in the bucket 42, and carries out dehydration procedure then.
Illustrate that referring now to Figure 12 the present invention controls the method for washing machine.
At first, if dehydration procedure begins, the weight of clothing and type are detected in the wash bucket, set dewatering time (step 10 and 12).
After dewatering time was set, (step 14) was dewatered by the rotation wash bucket.
When wash bucket began to rotate, controller 70 was checked the signal (step 16) that uneven checkout gear sends.
Then, controller detects when whether being included in washing machine work in the signal of input because of the uneven rotation of wash bucket or door and opens " height " signal (step 18) that produces.
If detect " height " signal, whether the duration of controller is determined detected " height " signal is in the scope of 24-450 millisecond (step 20).
If it is in 24-450 millisecond scope, controller determines whether described " height " signal in scope is detected more than three times.If " height " signal in 24-450 millisecond scope is detected more than three times, controller determines that wash bucket is in non-equilibrium state rotation (step 22).
Then, controller determines whether the such imbalance rotation of wash bucket is recurred more than three times (step 24).
If the rotation of the imbalance of current wash bucket is to take place for the third time, controller determines that abnormality takes place, and utilizes display and buzzer to notify the user.
On the other hand, in step 24,, be for the first time or the second time, carry out a uneven solution process (step 28), and turn back to step 14 then, restart dehydration procedure if the uneven rotation of the wash bucket of current generation is less than for the third time.Because the imbalance rotation of wash bucket mainly is because due to washing clothes conglomeration or the uneven distribution, uneven solution process comprises to bucket supplies with the water yield of setting, and wash bucket rotation preset time.
On the other hand, in step 20, if the duration of " height " signal not in 24-450 millisecond scope, controller determines that whether it is greater than 450 milliseconds.If the duration of " height " signal is greater than 450 milliseconds, controller is determined door be opened (step 30).
If the duration of " height " signal is not more than 450 milliseconds, the duration of this meaning " height " signal is less than 24 milliseconds.At this moment, controller is considered as it can continue to carry out continuously the dehydration procedure of step 14 by the noise of bascule (not shown) solution, and checks input signal.
In step 30, if determining door, opens by controller, it stops drive motors, and notifies the user (step 32) by display and buzzer.Then, after the scheduled time of rising when door is opened, controller determines whether door closes (step 34).If door is closed, controller is proceeded the dehydration procedure of time remaining in step 14.
On the other hand, in step 22, if " height " signal in 24 milliseconds of-450 milliseconds of scopes does not have continuous detecting more than three times, whether controller is considered as the slight non-equilibrium state that can solve by bascule to this, and determine the dewatering time that is set to stop and do not carry out uneven solution process (step 36).If the dewatering time that is set stops, dehydration procedure finishes, otherwise controller continues to carry out continuously the dehydration procedure of step 14.
As above describe in detail, washing machine of the present invention has a uneven checkout gear, and it comprises reed switch substantially, and it has by magnetic control and is encapsulated in contact point in the glass tube; Provide the magnet in magnetic field with contact point to reed switch.
The structure of uneven checkout gear like this in laundry or dehydration procedure, when detecting uneven rotation of wash bucket and door opening and closing state, can prevent the fault that is caused by moisture content or exotic.
And, use the uneven checkout gear of this spline structure, can prolong its service life, thereby improve the performance of washing machine.
In addition, uneven checkout gear simple in structure of the present invention can detect any unbalance dynamic of wash bucket and the on off state of door, makes part count reduce, and the space utilization rate improves in the washing machine.
