When cam wheel 26 is positioned at origin position, the first cam follower 49 of axis-shaped component 29 abuts with the first cam part 44a with the inspection ice of the first cam surface 44, and inspection ice component 4 is in the state risen to above ice container.In addition, the second cam follower 53 of switch lever 32 abuts with switch connection the first cam part 46a, and switch 31 is in the state of connection, and exports the signal of ice amount detection.
During initialization release, supply water to ice-making disc 2, and set timer (step ST2).
Within the stipulated time set by timer, control part utilizes the temperature of thermistor to ice-making disc 2 to detect.The temperature of ice-making disc 2 for below regulation, when producing ice in ice-making disc 2, control part drive motor 25 and start to shovel ice action.When starting to shovel ice action, synchronously starting ice amount with the action of shovel ice and confirming action (step ST3).
Step ST3 is described in detail, cam wheel 26 rotates around counterclockwise (CCW direction) under the effect of the rotary driving force of motor 25, second cam follower 53 and the switch of switch lever 32 disconnect and abutting with the first cam part 46b, make switch 31 be in the state of disconnection.Thereupon, the rotating shaft 17 shoveling out component 3 pivots, and shovels out sheet 18 and starts to rotate from the position shown in Fig. 1 towards the ice surface in ice-making compartment 12.In addition, cam wheel 26 rotates from origin position and the first cam follower 49 is slided at inspection ice the second cam part 44b, and thereupon, axis-shaped component 29 rotates and makes the arm of inspection ice component 4 start to decline.
When cam wheel 26 further rotates and reaches ice amount confirmation position, control part confirms whether switch 31 outputs signal (step ST4).Be set up in above-mentioned ice amount acknowledgement bit, the second cam follower 53 of switch lever 32 is in the position that can abut with the second cam part 46c with the switch connection as the region exporting the signal that ice amount confirms.
At this, in step ST4, as long as do not contain ice in ice container, the decline of inspection ice component 4 would not be hindered.Therefore, the first cam follower 49 of axis-shaped component 29 slides into inspection ice the 3rd cam part 44c as inspection ice component 4 being maintained the region of the state dropping to extreme lower position on cam surface.Axis-shaped component 29 rotates extremely as 30 degree of maximum magnitude, and inspection ice component 4 drops to lowest point.Now, when the anglec of rotation of axis-shaped component 29 reaches 20 degree, the blocking portion 51 of pressing of axis-shaped component 29 abuts with switch lever 32, thus stops switch lever 32 to press switch 31.Therefore, switch 31 maintains off-state.
When not exporting through the preceding switch 31 of stipulated time the signal that ice amount confirms at drive motor 25, control part is judged as that ice container is not filled.Now, control part continues drive motor 25, to proceed the shovel ice action (step ST5) making cam wheel 26 rotate around counterclockwise (CCW direction).In addition, at drive motor 25 after the stipulated time, the energising of heater 15 is carried out.The ice utilizing the heat of heater to depart from from the inner surface of ice-making compartment 12 shovels out to the outside the width of ice-making compartment 2 by shoveling out sheet 18, and falls down in the ice container to ice-making compartment 2.
When continuing drive motor 25 further, when making cam wheel 26 further rotate and arrive origin position, switch lever 32 is driven in switch connection makes switch 31 output signal with the first cam part 46a.When control part confirms that switch 31 outputs signal, be judged as origin position, and motor 25 is stopped.
Before cam wheel 26 returns origin position, the first cam follower 49 of axis-shaped component 29 slides into inspection ice the first cam part 44a from inspection ice four-cam portion 44d.Inspection ice component 4 is back to the origin position (step ST6) shown in Fig. 1, and the sheet 18 that shovels out shoveling out component 3 is also back to the origin position (step ST7) shown in Fig. 1.
On the other hand, in step ST4, if contain the ice of more than ormal weight in ice container, then can hinder the decline of inspection ice component 4.Now, because inspection ice component 4 cannot drop to lowest point, therefore the rotation of axis-shaped component 29 stops in a certain angle.
Now, if the anglec of rotation of axis-shaped component 29 reaches 20 degree, then the blocking portion 51 of pressing of axis-shaped component 29 abuts with switch lever 32, thus stops switch lever 32 to press switch 31.Therefore, switch 31 maintains off-state.Now, due to do not export before the stipulated time ice amount confirm signal, therefore control part is judged as that ice container is not filled.In contrast, if the anglec of rotation of axis-shaped component 29 does not reach 20 degree, then press blocking portion 51 and do not abut with switch lever 35, thus the swing of switch lever 32 can not be hindered.Like this, the second cam follower 53 of switch lever 32 disconnects from switch and slides into switch connection the second cam part 46c with the first cam part 46b.By this, switching manipulation portion 54 presses switch 31 and switch 31 is connected, thus exports the signal of ice amount confirmation.
When outputing through the preceding switch 31 of stipulated time the signal that ice amount confirms at drive motor 25, control part is judged as that ice container is filled.Now, control part make cam wheel 26 clockwise (CW direction) rotate, till switch 31 output signal next time, namely until switch lever 32 the second cam follower 53 switch connection with on the first cam part 46a slip till (step ST8).Then, when outputing signal, motor 25 is stopped.By above-mentioned action, cam wheel 26 is stopped on origin position.
When control part is judged as that ice container is filled, after the stipulated time, repeatedly carry out the action of step ST2 ~ step ST8.
About the action of shovel ice, use Fig. 8 to be described in detail, in step ST3, when starting to shovel ice action, as shown in Fig. 8 (a), the sheet 18 that shovels out shoveling out component 3 is arranged on origin position.When control part in this case continues drive motor 25 and starts to shovel ice action, shovel out component 3 and rotate centered by rotating shaft 17.Shovel out component 3 for a pair to be linked to constant speed by pair of cams gear 26, thus reversely rotate each other centered by rotating shaft 17.Thereupon, shovel out sheet 18 to enter in ice-making compartment 12.Represent by the order of Fig. 8 (b) ~ Fig. 8 (f), shovel out sheet 18 inner side from the width direction to rotate in the lateral on width, to make its inner side on the width of ice-making compartment 12 contact with ice 55, and from the position of contact, ice 55 is extruded towards the outside on the width of ice-making compartment 12.
When cam wheel 26 rotates 59.5 degree from origin position, shovel out sheet 18 as shown in Fig. 8 (b), be configured in (level) on the position parallel with the surface of ice., by control part, heater 15 is energized this moment, ice-making disc 2 is heated.By this, deice (surface of the ice contacted with the inner surface of ice-making compartment 12 is melted) from the inner surface of ice-making compartment 12.When cam wheel 26 further rotate, rotate to 90.5 degree time, shovel out sheet 18 and abut with the surface of ice 55.If can deice at the moment, then by making cam wheel 26 further rotate, can utilize and shovel out sheet 18 by ice 55 towards the outside carrying on width.On the other hand, if fully do not deice at the moment, then make stepping motor step-out until can fully deice, thus continue the torque to shoveling out sheet 18 applying regulation.By above-mentioned action, can make ice 55 can not excessive melting.
Then, when making the front end shoveling out sheet 18 reach the position of the outboard end on the width of ice-making compartment 12 when making cam wheel 26 rotate, as shown in Fig. 8 (f), ice 55 turn to smooth upper surface and overlays on and shovel out on sheet 18.Now, above-mentioned smooth upper surface is shoveling out on sheet 18 to tilt in the mode downward of the outside on width.Therefore, ice 55 can along shovel out sheet 18 inclination and towards the outside landing on width.By this, ice 55 is made to be shoveled out.The ice 55 of landing is housed in the ice container be positioned at below ice-making disc 2.
Now, as mentioned above, the radius of curvature that the radius of curvature that the inner surface of each ice-making compartment 12 is configured to start the inner surface of the inner side on the width of the inner surface of side as extrusion when extruding ice 55 compares as the inner surface in the outside extruded on the width of the inner surface terminating side is little.Due to the surface of ice 55 that contacts with the inner surface of the inner side on width before shovel ice action by shovel out action (extrusion action) and with radius of curvature larger than the radius of curvature of the inner surface of above-mentioned inner side, the inner surface in outside on more smooth width contacts, therefore can more swimmingly ice 55 be extruded.
In addition, if make ice 55 easily extrude as mentioned above, when ice-making compartment 12 just can be made darker, ice 55 not easily shovels out such situation and is improved, and therefore, ice-making compartment 12 can be made darker, thus make the size of obtained ice 55 larger.
In addition, because when ice 55 falls down, ice 55 overturns and shoveling out on sheet 18, the part that the inner surface of the inner side on therefore less with radius of curvature width contacts is positioned at more by the position in the outside on width.Namely, when the ice 55 being in state shown in Fig. 8 (f) falls down, because the center of gravity of ice 55 is more by the outside on width, therefore, turn to the ice 55 shoveled out on sheet 18 and not easily move to inner side on width, thus ice 55 can be made reliably to fall to outside on width.
In addition, as mentioned above, reversely rotate owing to making to shovel out component 3 for a pair, and the ice 55 produced is fallen down towards the outside of two on width, therefore, can not interfere with each other when ice 55 adjacent in the direction of the width falls down.Therefore, the moving direction of ice 55 can be made to stablize.In addition, owing to making the ice 55 produced fall down in two outsides of width, ice 55 in ice container therefore can be avoided to occur concentrating.By this, to correctly judge whether filled with ice by inspection ice action.And, in the structure that two outsides are in the direction of the width fallen down, do not need the inner side on the width of ice-making disc 2 that special hole of falling down for ice is set, therefore, ice-making disc 2 can be made to be integrally constituted, also can reducing portion number of packages.
In addition, because a pair shovels out the rotating shaft 17 of component 3 in the horizontal direction side by side, the ice 55 therefore fallen down can not disturb with other ice-making compartment 12.In addition, owing to setting phase place in the mode that sheet 18 is in mutual one-tenth face symmetry each other that shovels out shoveled out between component 3, therefore the balance of power is better.
Above, embodiments of the present invention have been described in detail, owing to being the ice maker that can make the increase excellent effect of the ice making number of chambers relative to the increase of the overall size of ice maker, the space arranged for refrigerating chamber (ice-making compartment) and the door of refrigerator diminishes, therefore, the refrigerator that energy Special composition efficiency is higher.In addition, the present invention is not limited to above-mentioned embodiment, can carry out various change in the scope not departing from thought of the present invention.
Such as, in the present embodiment, ice 55 is shoveled out towards two outsides on the width of ice-making disc 2, but the hole of falling down for ice also can be set in the inner side of the width of ice-making disc 2, the direction of rotation that shovel out component 3 relative across the hole of falling down for ice is set as rightabout (in the other direction), and inwardly rotate to the inner side on the width of ice-making disc 2, fall down the hole of falling down for ice to the inner side on the width being located at ice-making disc 2 to make ice 55.Now, the inner surface starting side due to extrusion when extruding ice 55 is the inner surface in the outside on width, extrude the inner surface that the inner surface terminating side is the inner side be positioned on width, therefore, it is preferable that, the radius of curvature that the inner surface of ice-making compartment 12 is configured to as the inner surface in the outside extruded on the width of the inner surface starting side is less than the radius of curvature of the inner surface as the inner side extruded on the width of the inner surface terminating side.In addition, in order to swimmingly ice be extruded, it is preferable that the extrusion be set to when making by shoveling out sheet 18 and being extruded from ice-making compartment 12 by ice 55, the radius of curvature of the inner surface of side is less than the radius of curvature extruding the inner surface terminating side, even if but the radius of curvature of also can be the radius of curvature that makes extrusion start the inner surface of side with extrusion the terminate inner surface of side is identical also by force ice can not be extruded such structure.In addition, also suitably can adjusting the hole across falling down for ice and the relative direction of rotation shoveling out component 3, falling down outside on the width of ice-making disc 2 and inner side to make ice 55.
In addition, even if when ice 55 is shoveled out towards two outsides on the width of ice-making disc 2, the sheet 18 that shovels out shoveling out component 3 is also not limited to and rotates in the inside facing outward side direction the width of ice-making compartment 12 respectively, also can be inside facing outward side direction inner rotary from the width direction respectively.Now, shovel out after the outside of sheet 18 on the width of ice-making compartment 12 abut with ice 55, ice 55 extrudes from ice-making compartment 12 by inner side in the direction of the width.That is, extrusion beginning side is the outside on width, and extrusion end side is the inner side on width.Now, as long as the radius of curvature being configured to the inner surface making the radius of curvature of the inner surface in the outside on width than the inner side on width is little.In addition, between ice-making compartment 12 that also can be adjacent on the width of ice-making disc 2, partition being set in the mode erected from the surface of ice-making disc 2, not disturbing when extruding each other to make ice 55 adjacent on the width of ice-making disc 2.In addition, also gear etc. can be set between pair of cams gear 26,27, become equidirectional to make the direction of rotation of pair of cams gear 26,27.
In addition, shovel out in component 3 at one, multiple sheet 18 that shovels out also can be made not give prominence in the same direction each other.Such as, also can be make length direction is positioned at the sheet 18 that shovels out separating a position to give prominence to towards mutually identical direction each other, and make the adjacent structure shoveling out sheet 18 phase place each other and stagger in the circumferential on length direction.In addition, consider the balance of power, preferably phase settings is become to make to shovel out and adjacently on the width between component 3 shovel out sheet 18 to be in mutual face each other symmetrical, but also phase settings can not be become make to shovel out and adjacently on the width between component 3 shovel out sheet 18 to be in mutual face each other symmetrical.In addition, shoveling out the situation that component 3 is not limited to two, also can be arrange the structure of more than three accordingly in the direction of the width with the columns of ice-making compartment 12.Now, need the inner side on the width of ice-making disc 2 that the hole of falling down for ice is set, fall down to make the inner side of ice 55 on the width of ice-making disc 2.
As drive source, dc motor also can be adopted to replace stepping motor.In addition, in the above-described embodiment, drive source is one, but also can adopt plural drive source.
