As previously mentioned, the heater in the ice machine 15 is used pushing away ice action time side.That is to say, start heater 15 and just mean the beginning that pushes away the ice action, and the stopping to heat and promptly mean the end that pushes away the ice action of heater 15.Therefore, the break-make control procedure to the heater among the present invention 15 will be illustrated in the lump with the frame for movement that pushes away the ice action.
As shown in Figure 2, motor 30 is power set of ice machine, except that for the rotation that pushes away ice bar 14 provides the power, also provides power for the cam 36 that detects full ice.
Push away the position of ice bar 14 for sensing, side at the gear 59 that is driven by motor 30 has been installed first magnet 56, the first sensor 53 that is used for sensing first magnet 56 has been installed on control panel 48, push away in the coaxial rotating shaft 51 that is installed in gear 59 of 14 on bar of ice, promptly push away ice bar 14 and gear 59 coaxial rotation.When first magnet 59 forwarded the sense position of first sensor 53 to, first sensor 53 will push away ice bar 14 initial position sensing signals; Therefore, first magnet 56 and first sensor 53 should be installed on the position that can sense the initial position that pushes away ice bar 14.
In addition, the 3rd magnet 55 also is housed and also can be sensed by first sensor 53 at the opposite side of gear 59, the installation site of the 3rd magnet 55 pushes away ice cube the position of ice build-up tank 12 corresponding to pushing away ice bar 14.Therefore, if the 3rd magnet 55 is also sensed after by first sensor 56 sensings arrives for first magnet 56, then can judge to push away the ice release.
The cam 36 of coaxial rotation is installed in the rotating shaft 51 of gear 59, and it rotates by crank 39 and makes ice exploration bar 16 move up and down and make the prolongation 45 with ice exploration bar 16 interlocks to rotate with moving of crank 39.Second sensor, 62, the second sensors 62 that one end of prolongation 45 is equipped with second magnet 65 and sensing second magnet 65 is installed on control panel 48 are installed in and can sense the position that ice exploration bar 16 is in full ice position.When second magnet 65 forwarded the sense position of second sensor 62 to, second sensor 62 promptly sent sensing signal, promptly confirmed to be filled with in the ice storage appts. the full ice signal of ice cube.
As mentioned above, first sensor 53 is sensors that sensing pushes away ice bar 14 initial positions, sends the initial position sensing signal when first sensor 53 senses first magnet 56.What is called pushes away the initial position of ice bar 14, is meant that pushing away ice bar 14 is in arbitrary position outside the ice build-up tank 12, and first sensor 53 is then wanted sensing the 3rd magnet 55 and sent to push away to ice and move the signal of finishing after sensing first magnet 56.Therefore, the interval between first magnet 56 and the 3rd magnet 55 will be set for and can sense the moment that ice cube is released from ice build-up tank 12; That is to say that if the position of first magnet 56 changes, the position of the 3rd magnet 55 also should corresponding change.
In the present invention, after control part 70 is judged the initial position that pushes away ice bar 14 according to the sensing signal of 53 pairs first magnet 56 of first sensor, push away finishing of ice action according to the sensing signal judgement of 53 pairs the 3rd magnet 55 of first sensor again through official hour, also promptly judge the time point that disconnects heater 15 along with the end that pushes away the ice action.The above-mentioned first sensor 53 and second sensor 62 are installed on the same control panel 48 and switch on simultaneously and realize control, and control part 70 preferably also is arranged on the same control panel 48.For making the first sensor 53 and second sensor 62 possess sensing function, control part 70 will be powered and be controlled and finish simultaneously by power supply 72; And this power supply 72 also will provide power supply for temperature sensing portion 82.
As shown in Figure 3, control system of the present invention comprise drive motors 30 motor driving part 74, by feed pipe connecting portion 4 drive when ice build-up tank 12 water fillings solenoid-driven portion 76 of magnetic valve (not shown), as required select timing timing portion 78, sensing ice build-up tank 12 temperature and be sent to the temperature sensing portion 82 of control part 70.Control system of the present invention also comprises the heater-driven portion 80 that drives heater 15, the break-make of this heater-driven portion 80 control heater 15 under the control of control part 70, particularly the turn-off time of heater 15, point should be the time point that first sensor 53 senses the 3rd magnet 55.The signal input part 73 of control system of the present invention comprises selectable sense switch, and when pressing sense switch, control part 70 can detect each member of ice machine.Therefore, control part 70 need possess the function of selecting situation that each member of ice machine is detected according to Test Switchboard, and these measuring abilities are by realizing feedwater action, the ice making action set and the Total Test that pushes away ice action etc.
In addition, also comprise the display part 81 of display control unit 70 controls operating state down among the present invention, display part 81 is provided with and can makes people also can change the light on and off cycle according to trouble location with the luminescent device of vision or sense of hearing identification and buzzer to show.Therefore, utilize a display device can show a plurality of trouble locations.
Fig. 4 a is the flow chart that detects the ice machine action among the present invention.
Selected the Test Switchboard of signal input part 73 as the user after, control part 70 promptly begins to detect the control procedure (300 step) of the driving condition of all required drive units of ice machine operate as normal.
At first, the operating state of various sensors is checked (310 step) in 70 pairs of ice machines of control part.For example, under the situation of cutting off temperature sensing portion 82 power supplys, detect by the signal of temperature sensing portion 82 input control parts 70 and with this and judge whether operate as normal of temperature sensing portion 82.Except this method, the measured value and the standard value of temperature sensing portion 82 in action initial stage or the action can also be compared, and judge whether operate as normal of temperature sensing portion 82 with this; At this, detected temperature range is set in standard value during with temperature sensing portion 82 operate as normal.In above-mentioned steps, except temperature sensing portion 82, also can detect the first sensor 53 and second sensor 62.In the process that various sensors are detected, if judging a certain sensor is in abnormality, then control part 70 will be to the control shown in the display device mapping 4b of display part 81.
When the detected value of certain sensor exceeds the regular event scope (600 step), control part 70 will be discerned its (610 step) by reading this detected value, and control display device the light on and off cycle be bright 1 second, go out 1 second (620 step), this light on and off cycle is that the control cycle when unusual appears in pre-set sensor, also be that each member of control part 70 identification ice machine take place by the light on and off cycle that need control when unusual, the set value in this light on and off cycle should be stored in the inside of control part 70.
When judging various sensors all normally carrying out in 310 steps, whether the position that control part 70 just pushes away judgement ice bar 14 is in normal initial position (320 step), and its flow process as shown in Figure 5.
After the ice machine power supply, control part 70 promptly sends the driving signal to sensor power supply 72, providing power supply (100 step) to the first sensor 53 and second sensor 62, but the first sensor 53 and second sensor 62 promptly enter the state of sensing first magnet 56, second magnet 65 and the 3rd magnet 55.
Afterwards, control part 70 at first will confirm whether sent sensing signal (110 step) from second sensor 62.In the present invention, completely icing sensing is to be undertaken by moving up and down of ice exploration bar 16.When ice storage appts. was not filled with ice cube, ice exploration bar 16 was in upper shown in Fig. 9 b, and second sensor 62 sends the sensing signal of sensing second magnet 65; But no longer include the position of rotation amount at cam 36, when promptly crank 39 breaks away from cams 36, ice exploration bar 16 will be in shown in Figure 2 the next, the sensing signal of second sensor, 62 sensings, second magnet 65 will disappear in fixed time.And under full ice state, be about to push away after the ice action stops, ice exploration bar 16 will rest on upper shown in Fig. 9 b, and second sensor 62 will continue to send the sensing signal of sensing second magnet 65 and the state that senses full ice.In 110 steps, if sensed full ice signal, then ice machine stops ice making (120 step), drops outside ice storage appts. to avoid Manufactured ice cube.
In 110 steps, if do not sense full ice state, control part 70 will judge whether first sensor 53 has sensed the initial position (130 step) that pushes away ice bar 14, judge promptly whether first sensor 53 has sent sensing and pushed away the signal of icing bar 14 initial positions.Along with the rotation of motor 30, push away ice bar 14 will with gear 59 coaxial rotation; When gear 59 rotations were a certain amount of, first sensor 53 should sense first magnet 56 and send the initial position sensing signal.In 130 steps, if first sensor 53 does not send the initial position sensing signal, mean that then pushing away ice bar 14 is not on the initial position, control part 70 promptly sends motor drive signal to motor driving part 74, makes motor 30 driven wheels 59 and pushes away ice bar 14 and rotate synchronously; Meanwhile, with 78 initialization of timing portion and begin motor and rotate timing (150 step).In 150 steps, if first sensor 53 has sent sensing first magnet, 56 initial position sensing signals (160 step), then control part 70 can judge that pushing away ice bar 14 is in initial position in the motor rotation time of regulation, and its state is shown in Fig. 9 a.In 160 steps, the motor rotation time of regulation slightly increased than the time (about 3 minutes) that pushes away 14 one weeks of rotation of ice bar, was about 4 minutes.Under the normal condition, in official hour, pushing away ice bar 14 is rotatable weeks; Therefore, even initial position farthest also can sensedly arrive.But in 160 steps, the rotating speed of motor 30 must remain a constant speed.If first sensor 53 does not send the initial position sensing signal in official hour, then can judge gear 59 and unusual the rotation, for example push away ice bar 14 and freeze together with water.In 160 steps, promptly sensed the initial position signal that first sensor 53 sends, then can carry out ice making operation (140 step); Otherwise, will push away ice operation (170 step), promptly utilize heater 15 to force heating.In the ice making operation of 140 steps, be positioned at outside the ice build-up tank 12 owing to push away ice bar 14, so needn't worry to freeze together with water.
As shown in Figure 5, push away in the process of ice bar 14 initial positions in detection, can sense motor 30 whether driven push away ice bar 14 and rotate, in the time of setting, push away ice bar 14 and whether be in normal initial position; Whether also can sense full ice sensing can normally realize.And, control part 70 also can in 160 steps the fixed time adjust.In said process, if judging motor 30 breaks down, control part 70 promptly carries out the motor braking fault shown in Fig. 4 c and shows control.
When motor 30 breaks down (700 step), the light on and off cycle that control part 70 will be discerned (710 step) to electrical fault and control the display device of display part 81 by process shown in Figure 5 is bright 0.5 second, go out 0.5 second, bright 0.5 second again, go out 1 second (720 step) this light on and off cycle and the light on and off cycle of the aforementioned demonstration sensor abnormality action different kenel of comparing again.
Shown in Fig. 4 a, next will detect magnetic valve action (330 step), its flow process is as shown in Figure 6.Magnetic valve is the parts of adjusting to ice build-up tank 12 water injection rates, promptly under the control of control part 70, injects the water yield of ice build-up tank 12 according to the signal adjustment of solenoid-driven portion 76 identifications.For this reason, control part 70 is at first with 78 initialization of timing portion (400 step), read then by the user and adjust the knob rotation amount of selected signal input part 73 and the feedwater time (410 step) that identification is set with reference to the knob rotation amount, after 76 identifications of solenoid-driven portion drive signal, promptly drive magnetic valve (420,430 step).After magnetic valve is driven, i.e. water filling in ice build-up tank 12,78 pairs of solenoid-driven time timing of timing portion; After the timing of timing portion 78 reaches setting-up time, control part 70 will be closed magnetic valve (440 step).Like this, the user just can adjust and inject not measuring of ice build-up tank 12.In said process, whether regular event also will be shown by the display device of display part 81 magnetic valve, but its light on and off cycle will be different with the aforesaid light on and off cycle.
After 330 steps detection magnetic valve, promptly begin ice making and detect (340 step), its flow process is as shown in Figure 7.The initial position that pushes away ice bar 14 is as shown in Figure 5 normally sensed and an amount of water has been injected in feedwater action shown in Figure 6 in ice build-up tank 12, then the ice making operation promptly begins, control part 70 is at first with timing portion 78 initialization (500 step) and judge whether timing reaches official hour (510 step), the time (about 1 hour) of the time set of afore mentioned rules for fully finishing ice making.Control part 70 will judge whether the temperature of the ice build-up tank 12 of 82 sensings of temperature sensing portion has reached the temperature (520 step) of finishing ice making, this temperature also will be set at the temperature that can fully finish ice making, when the condition of 510 steps and 520 steps is met, control part 70 will be made the judgement that ice making is finished.Whether that is to say, normally be to detect according to the time and the temperature that set to the ice making operation, and time and the temperature set all are adjustable.
The detection of carrying out at last is the detection (350 step) that pushes away the ice operation, and its flow process as shown in Figure 8.When the temperature of the ice build-up tank 12 of temperature sensing portion 82 sensings reached the temperature of finishing ice making, control part 70 promptly sent the driving signal to heater-driven portion 80, made heater 15 begin heating (200 step); Along with the heating of heater 15, the ice cube of ice build-up tank 12 walls melts gradually and is in active state.Control part 70 begins to heat timing (210 step) by timing portion 78 when control heater 15 begins to heat, be set at the time that ice build-up tank 12 wall ice cubes are melted heat time heating time.Before drive motors 30, control part 70 will receive the initial position signal (230 step) that pushes away ice bar 14 of first sensor 53 sensings, and its operating state is shown in Fig. 9 a.Next, control part 70 sends to motor driving part 74 and drives signal and drive motors 30 (240 step), and gear 59 is iced bar 14 coaxial rotation with pushing away, and the 3rd magnet 55 that is installed on the gear 59 also rotates thereupon.Along with the rotation that pushes away ice bar 14, the ice cube in the ice build-up tank 12 is pushed into outside the ice build-up tank 12 gradually and is fallen into the ice storage appts. of ice build-up tank 12 belows.In addition, when pushing away ice bar 14 and release ice build-up tanks 12, first sensor 53 will sense the 3rd magnet 55 (250 step) and sensing signal will be imported control part 70 at ice cube, and control part 70 will judge that ice cube has pushed away ice build-up tank, and operating state at this moment is shown in Fig. 9 c.Thereupon, control part 70 will send signal to heater-driven portion 80, make heater 15 stop heating (260 step).After above control procedure, when first sensor 53 sensed first magnet 56 once more, motor stopped operating, pushes away the ice operation and finishes (270 steps, 280 steps).In said process, 15 heat time heating times of 220 steps set heater are adjustable, and whether whether operate as normal, the particularly shutoff of heater 15 normally carry out by the sense conditions of the 3rd magnet 55 can to detect heater 15 with this.Whether operate as normal also will be shown by the display device of display part 81 heater 15, but the kenel in its light on and off cycle and aforesaid light on and off cycle is different.In addition, control part 70 is judged all members all during operate as normal in said process, and the display device of display part 81 will continue to keep the bright state that opens.
In sum as can be known, invention at first detects the state of all drive units of ice machine, and under normal condition, the display device of display part 81 will continue to keep the bright state that opens; Under abnormality,, can accurately judge the member that breaks down according to the different light on and off cycle of display device.
