The specific embodiment
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
As shown in Figure 2, heater 15 pushes away in the ice operation at ice maker and uses, i.e. the startup of heater 15 means that pushing away the ice operation begins, and heater 15 quits work and means that pushing away the ice operation finishes.So will be in conjunction with pushing away the explanation of ice Work machine structure to heater 15 open/close controls.
Motor 30 is to ice operation, provide power to pushing away ice bar 14 for finishing pushing away of ice maker.Motor 30 is returned full ice detection and is provided power with cam 36.Be that motor 30 is used to produce the ice maker required drive.
Utilize sensor and magnet to detect and push away the position of icing bar, promptly on certain position of transmitting gear 59 magnet 56 is being housed, and on certain position of the base plate 48 that gear 59 is housed, sensor 53 is being housed then driving by motor 30; And rotating shaft 51 coaxial dresses of gear 59 push away ice bar 14.Push away ice bar 14 and can rotate the amount of spin the same with gear 59.So be located at the magnet 56 with motor 30 linkage gears 59 certain position, sensor 53 just can be exported to push away and ice bar 14 initial position detection signals when forwarding sensor 1,53 sensed positions to.The installation site of sensor 53 and magnet 56 should push away ice bar 14 initial positions can detecting.
In gear 59 rotating shafts 51 cam 36 is housed, cam 36 is rotated by rotating shaft 51 revolving forces also.The rotation of cam 36 will pass to the armed lever 39 that ice exploration bar 16 is moved up and down.This by with ice exploration bar 16 interlock extension 46 1 sideway swivel amounts and the identical realizations of armed lever 39 amount of movements.
In extension 45 1 sides magnet 65 is housed, and is provided with on base plate 48 certain position to detecting the sensor 62 of magnet 65 positions, sensor 62 just is provided with at ice exploration bar 62 can detect whether position of full ice.When magnet 65 was gone to sensor 62 and can be detected the position, sensor 62 will output detection signal, and Here it is confirms the full signal of whether icing.
As shown in Figure 3, sensor 53 be push away ice bar 14 can detected sensor when being in initial position.Sensor 53 can send the initial position detection signal when sensing magnet 56.Said initial position is meant that pushing away ice bar 14 is not to be in the space that ice maker container 12 forms, but as shown in Figure 1, is in its top ad-hoc location.But, push away the initial position of icing bar 14 and there is no need to be confined to position shown in Figure 1.Only otherwise in the space that ice maker container 12 forms, any position can be set at initial position.
After sensor 53 is sensed magnet 56, again during induced magnet 55, will export and push away the ice operation and finish signal, and the spacing between magnet 56 and the magnet 55 should be set in and can detect all the time on the degree that ice cube breaks away from ice maker container.This just means the change along with magnet 56 initial positions, and the position of magnet 55 also will change.
After control part 70 judges that according to the induction of 53 pairs of magnet 56 of sensor pushing away ice bar 14 is in initial position, receive induced signal by sensor 53 again, judge that pushing away ice finished already magnet 55 through certain hour.Judge that promptly pushing away the required heater operation of ice should stop.Along with the induction to magnet 55 pushes away ice the finishing of operation, be in pushing away the process that the ice operation carries out, to realize.
Above-mentioned two sensors 53,62 are positioned on the same control base plate PCB, 48, can connect power supply simultaneously and realize control.If possible, control part 70 also is located on the same control base plate and is advisable.Control part 70 will be controlled the power supply to sensor 53,62, so that sensor 53,62 can detection signal.Above-mentioned control realizes simultaneously by probe power supply unit 72.Power suppling part 72 is also given the element that needs power supply except giving sensor 53,62, i.e. temperature induction part 82 power supplies.
In the control structure, also comprise motor driving part 74 and pass through feed pipe connecting portion 4 when ice maker container l2 supplies water, drive the water supply drive division 76 of solenoid valve.Symbol 78 be can be as required selectively the metering time timing portion that uses, the 82nd, induction ice maker container 12 temperature also are transferred to the temperature induction part of control part 70.
Also be included as the heater-driven portion 80 that drives heater 15.Heater-driven portion 80 realizes the ON/OFF of heater 15 is controlled by control part 70 controls.The moment of closing heater 15 must be the moment that sensor 53 is sensed magnet 55.
Symbol 73 is a signal input part.Signal input part comprises can be by the Test Switchboard of user's selection, if selected Test Switchboard, control part 70 will carry out the inspection to whole ice maker element.
According to the selection of Test Switchboard whether control part 70 will have for checking the audit function of element in the ice maker.Audit function is by water supply operation, the ice making operation set, the full test that pushes away ice operation etc. are realized.
Signal input part 73 comprises the rotary switch that can be regulated output by the user.Rotary switch can be contrasted rotation amount, and output increases to ice maker water supply signal.Signal is input to control part 70, and control part just can change the driving time of solenoid valve according to the variable quantity of rotary switch.The maximum rotation amount of rotary switch is the maximum ice-making capacity of ice maker container 12.
The following describes to checking the workflow of refrigerator with ice maker.As shown in Figure 4, when the user selects to be positioned at the Test Switchboard of signal input part 73, control part 70 begins to control driving condition inspection, the 300th stage to all required drive units of the normal operation of ice maker.Control part 70 is checked and is located at various working sensor states, the 310th stage in the ice maker.As temperature induction part 82.Under cutting off for temperature induction part 82 power supply status, detect the signal that is input to control part 70 from temperature induction part 82, just can judge whether the operation of temperature induction part 82 is normal.Except that this method, also can compare by detected value and standard value to initial operating stage or operating temperature induction part 82, judge whether normally operation of temperature induction part 82.When at this moment, standard value should be set in the normal operation of temperature induction part 82 in the detected temperature range.
The 310th stage was also checked the operation of sensor 53,62 except that checking temperature induction part 82.Promptly the 310th stage was the stage whether normal operation of various sensors that is contained in the ice maker is judged.The 310th stage was judged all normally operations of various sensors, and control part 70 will be checked the position that pushes away ice bar 14, judge that can it be in normal initial position, the 320th stage.
Power supply connects ice maker, and control part 70 will send the driving signal to probe power supply unit 72, makes it to sensor 53,62 power supplies, the 100th stage that are positioned on the control panel 54.By the control in the 100th stage, sensor 53,62 is connected power supply, but enters into induced magnet 56,65 states.Then, control part 70 confirms at first whether sensor 62 has detection signal output, the 110th stage.
The full ice of ice maker detects, and is to finish by moving up and down of ice exploration bar 16.Moving up and down of ice exploration bar 16 is when the rotation of motor 30 driven wheels 59, the rotation of the cams 36 that rotate under gear 59 revolving forces passed to that ice exploration bar 16 realizes by armed lever 39.
When the ice filling container that is positioned at the ice maker bottom did not have filled with ice, the ice exploration bar 16 above moving in cam 36 rotating ranges will be in Fig. 5 b position, and sensor 62 will send the induced signal to magnet 65.Rotate to the end the position at cam 36, be armed lever 39 when leaving cam 36, ice exploration bar 16 will reset to below shown in Figure 2.Promptly under non-full ice condition condition, sensor 62 is sensed detection signal that magnet 65 sends in the interior interruption of fix time.
Moving up and down of the ice exploration bar 16 whether this detection completely ices can periodically be carried out when ice cube drives for separating at motor 30.
When ice cube is in full ice state, move to the ice exploration bar 16 of top, even gear for separate ice cube rotate finish after, also can stay in position shown in Fig. 5 b.At this moment, sensor 62 signal of sensing magnet 62 will surpass institute and fix time and continue output.So control part 70 just continues induced signal by sensor 62, detects full ice state.
The 110th stage was that control no longer continues ice making for when being detected full ice state by sensor 62.Be and prevent that having filled ice cube because of the ice filling container makes the ice cube of then making drop to outside the ice filling container for the 120th stage.In the 110th stage, be judged as non-ly when completely icing state, control part 70 will judge whether sensor 53 detects initial position, the 130th stage that pushes away ice bar 14.That is, judging whether sensor 53 has sent detects the signal that pushes away ice bar 14 initial positions.
Pushing away the position of ice bar 14, is that the interlock when leaning on motor 30 to rotate is determined.That is, when gear 59 rotates by the rotation of motor 30, with gear 59 rotating shafts 51 coaxial push away ice bar 14 also along with rotation.Magnet 56 is equipped with in certain position of gear 59, and when gear 59 forwarded certain position to, magnet 56 was just sensed by sensor 53.At this moment, sensor 53 just sends the initial position detection signal.In the 130th stage, when sensor 53 was not exported the initial position detection signal, pushing away ice bar 14 was exactly to be on other positions of non-initial position.Be in ice maker container 12 spaces if at this moment push away ice bar 14, will take place and the icing together situation of water.So control part 70 will judge whether to have been sent pushing away the detection signal of ice bar 14 initial positions by sensor 53 in the 130th stage.
In the 130th stage, when sensor 53 was not exported the initial position detection signal, the motor driving part 74 of control part 70 will send motor drive signal.According to this signal, after motor 30 was driven, gear 59 was just followed rotation and drive to push away ice bar 14 and is rotated.Drive simultaneously at motor, the value of timing portion 78 will return zero, and begins to measure motor driving time, the 150th stage.The motor driving time that measures of the 150th stage fix time within the time, just output is to induced signal, the 160th stage of magnet 56 for sensor 53, control part 70 just can judge that position at this moment is to push away the initial position of icing bar 14.
The time of setting in the 160th stage is to push away ice bar 14 to rotate the time of enclosing after required time adds some make-up times.Usually push away the ice bar and rotate a circle and be about 3 minutes, institute fixes time and is decided to be 4 minutes and gets final product.
Under normal circumstances, in the time of setting in the 160th stage, push away the rotatable fully circle of ice bar 14, so even from farthest position of initial position the time, also can detect.Be necessary that the velocity of rotation of setting motor remains constant.This is that the control in the 160th stage is necessary.
As fix time in, sensor 53 does not have output to the induced signal of magnet 56, it is undesired just to be judged as gear 59 rotations that motor 30 drives.One of its example pushes away ice bar 14 exactly and freezes together with water, has hindered the rotation of gear 59, thus rotate undesired.
Detect the initial position that pushes away ice bar 14 in fixing time in the 160th stage, just can carry out the ice making operation in the 140th stage.Do not push away ice bar 14 initial positions and detect in fixing time in the 160th stage, that will carry out for the 170th stage pushes away the ice operation.The 170th stage push away the ice operation, isolate the process of ice exactly by force by the heating of heater.One of example is exactly to push away ice bar 14 and the icing together situation of water.When carrying out the 140th stage ice making operation, because push away ice bar (14) as shown in Figure 1, be in outside the space of ice maker container 12 formation, can prevent to freeze together with water.
When the initial position that pushes away ice bar 14 of Fig. 4 being detected with as above operational process, can detect push away ice bar 14 in fixing time and can be in normal initial position, and can the driving force of motor normal delivery be given and pushed away the ice bar so that it rotates etc.And, also can detect according to the full ice detection of sensor 2,62 detected values and whether normally carry out.In addition, control part 70 is by above-mentioned checking process, and making the time initial value that the 160th stage was set carry out variable adjustment becomes possibility.
Carry out inspection operation according to the 330th stage then to solenoid valve.Solenoid valve is used for regulating to ice maker container 12 outputs.That is, under the control of control part 70, according to the Signal Regulation that enters solenoid valve drive division 76 to ice maker container 12 outputs.Control part 70 is in order to regulate the output to ice maker container 12, first initialization timing the 78, the 400th stage of portion.Read in the rotation amount of signal input part 73 rotary switches of regulating by the user then and confirm water supply time, the 410th stage according to the rotary switch rotation amount by control part 70.In between the delivery period of the 410th stage affirmation, control part 70 send the driving signal will for solenoid valve drive division 76, so that drive solenoid valve, the 420th stage, the 430th stage).
During above-mentioned stage solenoid valve drives, ice maker 12 can obtain supplying water, timing portion 78 meterings driving time.To the time that sets according to timing portion 78, control part 70 will the closed solenoid valve, the 440th stage.
By these processes, the user just can regulate the output of giving ice maker container 12.In the water supply operation of Fig. 6, will pass through rotating signal input part 73 rotary switches, regulate the solenoid valve driving time, suitable up to the water yield of supplying with ice maker container 12.
Inspection finishes to solenoid valve in the 330th stage, will carry out the inspection of the 340th stage to the ice making operation.
The workflow that the 340th stage was checked the ice making operation as shown in Figure 7.
Normally detect according to Fig. 5 and to push away ice bar initial position, supplied with an amount of water for ice maker container 12, will carry out the ice making operation according to Fig. 6 operation of supplying water.
Control part 70 is wanted the 78, the 500th stage of initialization timing portion.And after the ice making operation began, whether the time of judging timing portion 78 metering has reached institute was fixed time about 1 hour, the 510th stage.Institute fixes time to be set at and finishes ice making institute adequate time.
Control part 70 will be judged the temperature that detects ice maker container 12 and whether the temperature induction part 82 detected temperature of establishing has reached the temperature that ice making finishes, the 520th stage.The temperature set of the 520th stage should be the ice making operation institute's temperature fully that finishes.
Satisfy the condition and the condition in the 520th stage in the 510th stage, control part 70 just can judge that ice making finishes.
So when checking the ice making operation according to Fig. 7, the time in the 510th stage that the detection ice making finishes and the temperature in the 520th stage all should be set proper.Also to detect under time that sets and temperature ice making and whether normally carry out, so that adjusting time and temperature.
Push away inspection, the 350th stage of ice operation.The 350th stage check push away the ice operation workflow as shown in Figure 8.
When temperature sensitive member 82 detected values reached ice making and finish value, control part 70 was just to heater-driven portion 80 output drive signals.At this moment heater 15 just begins heating, the 200th stage according to signal.
Heater 15 beginning adstante febres, the heat that heater produces passes to ice maker container 12.Melt so the ice cube under the ice maker container 12 is subjected to the heat of heater, become removable.
Control part 70 will make heater begin heating simultaneously in the 200th stage, begins metering time, the 210th stage by timing portion 78.Time measurement is the required time that makes bottom ice cube thawing by the heating of heater 15 in order to provide.The time that the 220th stage was set should be the time that ice can melt.
Control part 70 will detect the initial position that pushes away ice bar 14 according to magnet 56 earlier from sensor 53 before CD-ROM drive motor.Carry out when being in initial position pushing away ice bar 14 because of pushing away the ice operation, so normally carry out to detect under the situation initial position that pushes away ice bar 14 pushing away the ice operation.Control part 70 sends the driving signal will for motor driving part 74 afterwards, with CD-ROM drive motor, the 240th stage.
After 30 drivings of the 240th stage motor, the power of generation is passed to gear 59, and gear 59 rotations push away ice bar 14 and just can rotate together.At this moment, being positioned at gear 59 a certain locational magnet 3,55 also and then rotates.
On the one hand, push away the rotation of ice bar 14, can make ice cube icing in ice maker container 12, that melt the bottom under the heater heating be pushed ice bar 12 gradually and shift onto outside the ice maker container 12.This move continues to carry out in during pushing away ice bar 14 and rotating, and falls in the storage container that is positioned at the ice maker below thereby make ice cube break away from ice maker container 12.
Because of the rotation that pushes away ice bar 14 is to rotate with gear 59 to carry out simultaneously, when pushing away ice bar 14 and make ice cube break away from ice maker container 12, magnet 3,55 just can be sensed by sensor 1,53, the 250th stage.Detection signal is input to control part 70, and control part just can confirm that ice cube has broken away from ice maker container 12.Control part 70 just gives heater-driven portion 80 output stop signals, interrupts operation, the 260th stage of heater 15.
After suppressing the heater operation with above running, when magnet 56 can be sensed by sensor 53, stop the rotation of motor, push away that the ice operation has just been finished, the 270th stage, the 280th stage).That is, in the checking process that pushes away the ice operation according to Fig. 8, the initial stage that is adjustable as heater in the 220th stage drives the setting value of required driving time.And can also check whether normally operation of heater, can detect heater and whether normally close according to induction situation magnet.
The present invention can check that ice maker normally moves the driving condition of all drive units, also the initial set value set of variable adjustment.That is, comprise test function, whether the normal operation of judging all element is as basic fundamental thought.So can judge that appropriately whether the required initial set value of operation, is regulated initial set value again.
