The specific embodiment
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
As shown in the figure, move the position of ice lever by Hall element and magnet sensing.Gear 59 is by the revolving force rotation of motor 30, and an end of gear 59 is provided with magnet 56.Circuit board 48 1 ends that gear is housed are provided with Hall element 53.Move ice lever 14 be located at the same axle of gear rotating shaft 51 on.
The rotation amount of gear is with to move ice lever rotation amount proportional.When being located at magnet 56 arrival Hall elements 53 sense position of gear one end that rotates with the motor interlock, move the sensing signal of ice lever 14 initial positions from Hall element 53 outputs.But magnet 56 and Hall element 53 are located at sensing to be moved on the ice lever initial position part.The rotating shaft 51 of gear is provided with cam 36, and cam 36 can be received the revolving force of rotating shaft.The rotation amount of cam is passed to and can be made inspection ice lever 16 upper and lower mobile female lever 39 sides, because of and inspection to ice the amount of movement of lever-linked extension 46 1 sides identical with female lever amount of movement.Extension 45 1 sides are provided with magnet 65.Circuit board 48 parts are provided with the Hall element 62 that can detect magnet 65 positions, completely whether ice the position but Hall element 62 is located at inspection ice lever sensing.When magnet 65 arrived the Hall element sense position, from Hall element output sensing signal, above-mentioned signal was to confirm the full signal of whether icing.
Hall element 53 is to move ice lever 14 when being positioned at initial position, and sensing moves the sensor of ice lever initial position.During Hall element sensing magnet 56, the sensing signal of output initial position.Initial position refers to, moves the ad-hoc location that ice lever 14 is positioned at ice maker container 12, is not included in the ice maker container setting and moves in the spatial dimension of icing lever 14.But need not limit by position shown in Figure 1 and move ice lever 14 initial positions.Move if not above-mentioned ice maker container setting in the spatial dimension of ice lever 14, can be with initial position setting in any position.
Hall element 62 is inspection ice levers 16 when being positioned at full ice position, the sensor of sensing inspection ice lever.During Hall element 62 sensing magnet 65, the output sensing signal.
Hall element 53 output initial position sensing signals are passed to control part 70.Control part is that the benchmark judgement moves ice lever 14 positions with the Hall element output signal.The sensing signal of Hall element 62 outputs also is input to control part 70.Control part 70 is that benchmark is judged full whether ice by Hall element 62 output signals.
Because being contained on the control circuit board 54, Hall element 53 and 62 can form control simultaneously to they power supplies to them.As possibility, preferably also control part 70 is located at and Hall element 53, on the Hall element 62 same control circuit boards.Control part 70 controls are to Hall element 53,62 power supplies, but purpose is the sensing signal of control part receiver hole sensing output.Control is carried out simultaneously by Hall element power suppling part 72.Control structure also comprises: the drive division 74 of drive motors 30 when ice maker container is supplied water, drives helix tube feedwater drive division 74 by feed pipe linking part 4; The 78th, time timing portion, its effect is to select computing time as required.
Power to ice machine, at this moment control part 70 is to Hall element power suppling part 72 output drive signals, power supply is applied to is located on the Hall element 53,62 of control circuit board 54, control by the 100th stage is to Hall element 53,62 power supplies, the wait state that formation can sensing magnet 56,65.Confirm at first whether control part received from the 110th stage of sensing signal of Hall element 62 outputs.
Completely ice sensing in the ice machine and be upper and lower the moving by inspection ice lever, it is that gear 59 is received when rotating behind motor 30 power that inspection ice lever 16 upper and lower moved, and by 36 rotations of gear band cam, passes to through female lever 39 that inspection ice lever side 16 forms.Be located in the ice pan of ice machine downside when not being full ice state, the inspection ice lever 16 that cam 36 rotations are moved to top is positioned at position shown in Fig. 5 B, from the sensing signal of Hall element 62 outputs to magnet 65.But on cam 36 rotation end positions { when above-mentioned female lever (39) breaks away from from cam 36 }, above-mentioned as shown in Figure 2 inspection ice lever 16 comes back to the bottom.That is to say that when not being the situation of full ice, behind 62 pairs of magnet 65 sensings of above-mentioned Hall element, the output sensing signal finishes within a certain period of time.In order to move ice, when motor 30 produced power, the above-mentioned inspection ice lever of can sensing completely icing 16 that forms the cycle moved up and down work.Also promptly, dynamic Control portion cycle of transmitting power to inspection ice lever with move that to ice service cycle identical.
Under full ice state, the gear rotation that the inspection ice lever 16 that moves to top is moving ice work stops the back and continues to move and be parked on the position shown in Figure 5.At this moment, the sensing signal to magnet 65 from Hall element 62 outputs continues output more than certain hour.Control part continues output sensing signal sensing by Hall element 62 and completely ices state.
The effect in the 110th stage is by under the situation after completely icing from the sensing signal sensing of Hall element 62 outputs, can prevent more ice making.The ice that stores in the ice pan of ice is full, even continue ice making, but the ice of making drops to the ice pan outside, can prevent above-mentioned situation (the 120th stage).
When judgement is not full ice state in the 110th stage, control part 70 judge Hall element 53 whether sensing move the initial position (the 130th stage) of ice lever.Whether judgement exports moving the sensing signal of ice lever initial position from Hall element.
The position of moving ice lever 14 rotates interlock with motor 30 and forms.When gear 59 is received the rotation of motor 30 revolving forces, the ice lever that moves that is located on the same axle with gear rotating shaft 51 is rotated.Gear 59 1 ends are provided with magnet 56, when the rotation amount of gear 59 reaches certain degree, detect magnet 56 by Hall element 53, the sensing signal of Hall element 53 output initial positions.
In the 130th stage,, mean that moving the ice lever is not positioned at initial position but is positioned at other range position if when Hall element 53 is not exported the initial position sensing signal.When if this time shift ice lever 14 is positioned at the ice maker container spatial dimension, can produces to move and ice lever 14 and water freezes problem together.Therefore, in the 130th stage, control part is judged whether sensor 53 detects and is moved ice lever 14 initial position sensing signals.The 130th stage when above-mentioned Hall element 53 does not detect initial sensing signal, control part 70 is to the motor driving part output drive signal.By signal drive motor, make gear and move ice lever 14 rotate together.Drive motors calculates the motor-driven time (the 150th stage) simultaneously with after 78 value initializations of time timing portion.The motor-driven time of calculating exports magnet the 160th stage of 56 sensing initial position signals from Hall element 53 within a certain period of time, and control part is judged now for moving ice lever 14 initial positions.
For the certain hour that was located at for the 160th stage, to revolve the required time of turning around longer than moving ice lever 14 during setting-up time.Moving ice lever 14 revolves to turn around and takes about three minutes.Preferably certain hour is set about four minutes.Under the normal condition, move ice lever 14 and revolve and turn around owing to can make in the certain hour set of the 160th stage, but move ice lever 14 when being positioned at the distant position of initial position also sensing move ice lever 14.In addition, the actuating speed of motor is set on the certain speed, this is that the control of the 160th stage is needed.
If do not have the sensing signal of output from Hall element 53 within a certain period of time, can judge that the rotation of the gear 59 that motor-driven is carried out is undesired to magnet 56.When moving ice lever 14 and water and freeze together, the rotation of gear 59 is restrained, so gear can not normally rotate.So in the certain hour in the 160th stage, sense the initial position that moves ice lever 14, carry out ice making work in the 140th stage.If in the certain hour in the 160th stage, sense the initial position that does not move ice lever 14, move ice work according to the 170th stage.
The ice work that moves in the 170th stage refers to that producing heat by heater forces stage of moving ice, moves ice lever 14 and water and freezes together situation.If carry out ice making,, can prevent to move ice lever 14 and freeze together with water owing to move the spatial dimension of the ice maker container that ice lever 14 broken away from the 140th stage.Control part 70 supplies water to ice maker container by the control to feedwater drive division 74, and the running that ice making is needed is afterwards controlled.
Serviceability, the result of use of accompanying drawing illustrated embodiment are good.
