Upper end 24s is against the top.The operation from freezing cold handle 25 will not be interfered by geared parts as a result, to improve the behaviour from freezing cold handle 25
The property made can be easy to become ice-making disc 23 from ice posture.
Figure 11 to Figure 14 shows the action specification figure of ice maker, and Figure 11 is preoperative " ice-make condition ", Figure 12 and figure
13 are " from ice midway state ", and Figure 14 is " terminating state from ice " after operation.In addition, connection into Figure 14, is omitted in Figure 11
The diagram of plate 24e and shell 21, and ice-making disc 23 is shown in a manner of cross-sectional view.
As shown in figure 11, ice maker 20 is carrying out under preoperative " ice-make condition ", becoming the system of ice-making disc 23 from ice
The opening of ice portion 23a is towards the state above vertical direction.Also, in the system of (left and right directions of diagram) along the longitudinal direction arrangement
The boundary of ice portion 23a and ice making unit 23a, there are the rotation center P of driven gear 24d, and ice-making disc 23 is using rotation center P as base
It is quasi- and rotate.
A part by hinge side of the edge 23b4 close to ice-making disc 23 in framework 52a as rotation Ii miter 31,
The rotation Ii miter 31 be protruded above to the close direction of ice-making disc 23 it is raised.And play 23e's close to aixs cylinder for therein
One end is as rotation engaging portion 34, and the rotation engaging portion 34 is as the rotation predetermined angular β on the direction operated from ice1When, pass through
The rotation that the side 23e is played to aixs cylinder to inhibit ice-making disc 23 is abutted with the abutting side 32 of ice-making disc 23.
Driving gear 24c be located at the surface of driven gear 24d, and be configured to drive gear 24c rotation center Q and from
The rotation center P of moving gear 24d is overlapped in vertical direction.Also, front end (upper end) 25s ratio from freezing cold handle 25 drives gear
The upper end of 24c just protrudes more up.
The briefly shape using Figure 11 to the driving gear 24c and driven gear 24d that are formed as spiral-shaped gear
It is illustrated.
In being equipped with the range of the driven gear 24d tooth engaged for driving gear 24c, the first range 33a is in rotation
Maximum range at a distance from until heart Q to the meshing point 35 of the tooth engagement with driven gear 24d.
Third range 33c be rotation center Q to meshing point 35 until the smallest range of distance, be sandwiched in the first range
Second range 33b of the 33a between third range 33c be rotation center Q to meshing point 35 until at a distance from be changed to from maximum
The smallest range.First range 33a, the second range 33b and third range 33c are integrally formed into spiral shape.
In being equipped with the range of the driving gear 24c tooth engaged for driven gear 24d, the 4th range 33d is in rotation
The smallest range at a distance from until heart P to the meshing point 35 of the tooth engagement with driving gear 24c.
6th range 33f be rotation center P to meshing point 35 until the maximum range of distance, be sandwiched in the 4th range
Fiveth range 33e of the 33d between the 6th range 33f be rotation center P to meshing point 35 until at a distance from from minimum change to
Maximum range.4th range 33d, the 5th range 33e and the 6th range 33f are integrally formed into spiral shape.
In a manner of making to drive the 4th range 33d of the first range 33a and driven gear 24d of gear 24c intermeshing
To determine the shape of tooth.So that the 5th range 33e intermeshing of the second range 33b and driven gear 24d of driving gear 24c
Mode determine the shape of tooth.And so as to drive the 6th range 33f of the third range 33c and driven gear 24d of gear 24c
Intermeshing mode determines the shape of tooth.
The intermeshing state of the 4th range 33d, drive in the first range 33a and driven gear 24d of driving gear 24c
The intermeshing state of the 5th range 33e and driving gear of the second range 33b and driven gear 24d of moving gear 24c
In the state of the 6th range 33f intermeshing of the third range 33c and driven gear 24d of 24c, from the rotation of driving gear 24c
Turn center Q and is configured to equal via distance of the meshing point 35 until the rotation center P of driven gear 24d.
So as to be set to the number of teeth of the first range 33a of driving gear 24c and the 4th range 33d for being set to driven gear 24d
The number of teeth equal mode determine the number of teeth.So as to be set to the number of teeth of the second range 33b of driving gear 24c and be set to driven tooth
The equal mode of the number of teeth of the 5th range 33e of 24d is taken turns to determine the number of teeth.And so as to it is set to the third range of driving gear 24c
The number of teeth of 33c determines the number of teeth with the equal mode of the number of teeth of the 6th range 33f of driven gear 24d is set to.
The first range 33a of driving gear 24c is that reduction ratio is constant with engaging for the 4th range 33d of driven gear 24d
" constant region domains ".The second range 33b of driving gear 24c is reduction ratio with the engaging for the 5th range 33e of driven gear 24d
Change " region of variation " with rotation.Drive the 6th range 33f of the third range 33c and driven gear 24d of gear 24c
Engagement be that reduction ratio is constant " constant region domains ".
In Figure 11, the 4th range 33d intermeshing of the first range 33a and driven gear 24d of gear 24c, system are driven
Ice pan is horizontal " ice-make condition ".Drive gear 24c the first range 33a rotation center Q to meshing point 35 until away from
From being R1, the distance until the rotation center P to meshing point 35 of the 4th range 33d of driven gear 24d is R2, and is configured to R1
> R2.Become (R1+R2) at a distance between the rotation center PQ of driving gear 24c and driven gear 24d, in the present embodiment,
R1=28.5, R2=11.3, thus (R1+R2)=39.8, in addition to obtaining the backlash (gap) at the engaging section of tooth, preferably
Expand the distance between rotation center PQ and is allowed to as 40mm or so.
If gear 24c is driven to rotate the angle of the first range 33a, driven gear 24d rotates the angle of the 4th range 33d
Degree, thus angle ratios (angle of the 4th range 33d)/(angle of the first range 33a) become driving gear 24c with it is driven
The reduction ratio (or speed-up ratio) of gear 24d, the ratio between with radius, R1/R2 is equal for this.Under the ice-make condition of Figure 11, due to R1 >
R2, so driven gear 24d rotates while accelerating relative to driving gear 24c.That is, if by the driving gear in Figure 11
The reduction ratio (or speed-up ratio) of 24c and driven gear 24d is set as (1/N), then (1/N)=1/ (R2/R1) ≈ 1/ (11.3/28.5)
=(1/0.39)=2.53, so that about 2.5 times of ground are accelerated in the present embodiment.
Herein, the bigger denominator N for referring to (1/N) that slows down is larger, at this point, the gear with driving side drives gear 24c
Rotation angle compare, it is smaller by the gear of driving side, that is, driven gear 24d rotation angle, on the contrary to driving gear
When 24c is applied with certain torque, the torque for being transferred to driven gear 24d is big.
The smaller denominator N for referring to (1/N) that slows down is smaller, is at this time the rotation for driving gear 24c with the gear of driving side
Angle is compared, bigger by the gear of driving side, that is, driven gear 24d rotation angle, is applied on the contrary to driving gear 24c
When certain torque, the torque for being transferred to driven gear 24d is small.
In the case where N > 1, compared with the gear of driving side is to drive the rotation angle of gear 24c, by the tooth of driving side
Wheel is that the rotation angle of driven gear 24d is smaller, be from driving side to the state slowed down by driving side,
In the case where N < 1, on the contrary, bigger by the gear of driving side, that is, driven gear 24d rotation angle, be from
The state that driving is laterally accelerated by driving side.
Certainly, when N=1, driving gear 24c and driven gear 24d constant speed rotation.
Herein, since ice-making disc 23 and driven gear 24d directly link, thus make ice-making disc 23 rotate load torque with
The rotating torques of driven gear 24d are equal.Due to directly linking from freezing cold handle 25 and driving gear 24c, so operating from freezing cold
The operation torque of handle 25 is equal with the driving rotating torques of gear 24c.That is, being set as when by the operation torque for operating from freezing cold handle 25
T1 and by order to make that ice-making disc 23 rotates from ice when being set as T2 from ice torque, there is following relationship:
T1=T2 × [1/ (R2/R1)].
Under " ice-make condition " of Figure 11, [1/ (R2/R1)]=2.53 > 1, thus N=0.39 < 1 and accelerate, and by
In T1 > T2, so operating the operation torque T1 ratio from freezing cold handle 25 makes the bigger from ice torque T2 of the rotation of ice-making disc 23.
In the case where carrying out from ice operation, finger is put into the front end from freezing cold handle 25 by user, as illustrated in fig. 12
Make to fall from freezing cold handle 25 towards nearby inclination.As a result, connection (fixation) in the driving gear 24c from freezing cold handle 25 to illustrate up time
Needle direction rotational angle α 1.By making to drive gear 24c rotation, to make driven gear 24d rotate in an anti-clockwise direction angle to diagram
Spend β 1.Since ice-making disc 23 is via link plate 24e (referring to Fig. 7) and with connection (fixation) in driven gear 24d, so by making
Driven gear 24d rotation, to make ice-making disc 23 also rotate in an anti-clockwise direction angle beta 1 to diagram together.Herein, as said
It is bright such, there is β 1=α 1 × (R1/R2) relationship.
Until from Figure 11 to the state of Figure 12, ice-making disc 23 overcomes the active force of torsion-coil spring 23d, with driven tooth
It takes turns the rotation of 24d and integrally rotates.The rotating torques of ice-making disc 23 at this time are at most only the effects of torsion-coil spring 23d
Power M, operation torque T1 from freezing cold handle 25 become the active force M of torsion-coil spring 23d multiplied by the torque after (R1/R2),
It is expressed as T1=M × (R1/R2).
The state of Figure 12 show ice-making disc 23 rotated from making ice position angle beta 1 and abut side 32 be connected to rotation it is locking
" distortion starts " state in portion 34.Such as angle beta 1 is approximately 100 ° or so in the present embodiment.
Under the state, the near border and driven gear of the first range 33a and the second range 33b of gear 24c are driven
The tooth engagement of the near border of the 4th range 33d and the 5th range 33e of 24d.
Figure 13 shows " from the ice midway state " that angle [alpha] 2 is further rotated to from freezing cold handle 25.Driven gear 24d and
With the linking part 23c rotational angle β 2 of the ice-making disc 23 of driven gear 24d connection.On the other hand, approaching due to ice-making disc 23
The abutting side 32 of aixs cylinder 23e is connected to rotation engaging portion 34 and inhibits to rotate, so 23 distortion angle of ice-making disc (β 2- β 1),
Bend ice making unit 23a, to apply the power for being allowed to be detached from from ice-making disc 23 to the ice in ice making unit 23a.
At this point, the second range 33b and the 5th range 33e of driven gear 24d of driving gear 24c are the states engaged,
Distance until driving the rotation center Q to meshing point of gear 24c becomes R1 ", and the rotation center P of driven gear 24d is extremely engaged
Distance until point becomes R2 ".Reduction ratio at this time is (1/N)=[1/ (R2 "/R1 ")], the increased side of N with accompanying rotation
Formula variation.
The rotation center P of distance R1 " and driven gear 24d until driving the rotation center Q to meshing point of gear 24c
Distance R2 " until meshing point just changes whenever the engagement progress of tooth.That is, whenever to nearby operating from freezing cold handle 25, away from
It is reduced from R1 ", distance R2 " increases, so that the denominator N of reduction ratio 1/N=[1/ (R2 "/R1 ")] increases with rotation.That is, by
In from freezing cold handle 25 rotating gear with operation, the denominator N of reduction ratio increases, so being applied to ice making from from freezing cold handle 25
Disk 23 it is as larger to degree nearby rotating from freezing cold handle 25 in made from ice torque.
Herein, if so that driving gear 24c and driven gear 24d rotation and the engagement of tooth to adjacent tooth after mobile,
The rotation center P of reduction amount and the driven gear 24d of distance until driving the rotation center Q to meshing point of gear 24c are to nibbling
The equal mode of the incrementss of distance until chalaza, to set the shape of intermeshing tooth, then from rotation center Q via nibbling
Chalaza and distance and meshing point until rotation center P are unrelated and constant, to drive gear 24c and driven gear 24d energy
It is enough to be rotated while being intermeshed, and reduction ratio (1/N) can change with rotation.
Figure 14, which is shown, further rotates " terminating state from ice " until the angle [alpha] 3 as maximum displacement from freezing cold handle 25.
Driven gear 24d and with driven gear 24d connection ice-making disc 23 linking part 23c rotational angle β 3.The angle is, for example,
180 ° to 190 °, ice-making disc 23 essentially becomes the state inverted.
On the other hand, due to close to ice-making disc 23 aixs cylinder rise 23e abutting side 32 be connected to rotation engaging portion 34 and
About 100 ° or so inhibition rotations, so that both ends distortion angle (β 3- β 1) ≈ (80~90 °) of ice-making disc 23, makes ice making unit 23a
It bends to the maximum extent, and then can reliably apply to the ice in ice making unit 23a can be from the distortion of ice.
That is, the ice freezed in ice making unit 23a is because of ice-making disc before the distortion to " terminating state from ice " of ice-making disc 23
23 torsional deformation and from ice-making disc 23 be detached from and fall.It calls it as from ice.
Herein, the nearest third range of distance until driving the rotation center Q to meshing point in gear 24c, with it is driven
The 6th range engagement of the distance until rotation center P to meshing point farthest in gear 24d, if so as to being passed through from rotation center Q
The shape that tooth is set by distance of the meshing point until rotation center P mode identical with ice-make condition, then drive gear
24c and driven gear 24d rotates while being intermeshed.
Herein, the distance until driving the rotation center Q to meshing point of gear 24c is R1 ' ", the rotation of driven gear 24d
Distance until the P to meshing point of center is R2 ' ", reduction ratio at this time is (1/N)=[1/ (R2 ' "/R1 ' ")]=[1/ (21.6/
18.2)] [1/ (1.2)] ≈, R1 ' " being minimum value, R2 ' " are maximum values, so that the denominator N of reduction ratio (1/N) becomes maximum value
1.2, and the driving torque for being applied to ice-making disc 23 becomes maximum.
That is, the denominator N of the reduction ratio (1/N) in present embodiment is 0.4 at ice making position, at from ice end position
It is 1.2, so that the variation of reduction ratio is (1.2/0.4) i.e. about 3 times.
In the present embodiment, until since " ice-make condition " to " distortion ", the first range 33a of gear 24c is driven
It is intermeshed with the 4th range 33d of driven gear 24d, and drives the rotation angle of gear 24c and the rotation of driven gear 24d
Angle is proportional.
Until near since " distortion " to " terminating state from ice ", drive gear 24c the second range 33b with it is driven
The 5th range 33e of gear 24d is intermeshed, and driven gear 24d rotates while speed change relative to driving gear 24c,
In addition near " terminating state from ice ", the 6th range 33f phase of the third range 33c and driven gear 24d of gear 24c are driven
Mutually engagement, and drive the rotation angle of gear 24c proportional to the rotation angle of driven gear 24d.
When in the present embodiment, the rotation since " ice-make condition ", the first range 33a of gear 24c is driven
With the 4th range 33d of driven gear 24d intermeshing and reduction ratio is lesser first reduction ratio, so that ice-making disc 23 is larger
Ground rotation, on the other hand, at the end of " terminating state from ice " neighbouring rotation, drive the third range 33c of gear 24c with from
The 6th range 33f of moving gear 24d is intermeshed and reduction ratio is biggish second reduction ratio, so that ice-making disc 23 turns smaller
It is dynamic.
Herein, using Figure 15, in " ice-make condition " since Figure 11 via " state distortion " of Figure 12, Figure 13
" from ice midway state " and until " the terminating state from ice " of Figure 14, in order to which the rotation for rotating ice-making disc 23 and needing is negative
The characteristic of lotus torque is illustrated.
As described above, rotary load torque is only in the range of until since " ice-make condition " to " state distortion "
The active force of torsion-coil spring 23d, and according to spring constant and with the torsional displacement of ice-making disc 23 proportionally substantial linear
Ground increases.
Since " distortion state " via " from ice midway state " and until " terminating state from ice " until, according to " torsion
Rotation angle after bent beginning state " distorts ice-making disc 23.Therefore, the rotary load torque of ice-making disc 23 becomes torsion
The active force of helical spring 23d and rotating torques for distorting ice-making disc 23 it is total.The rotary load torque have with
The distortion angle of ice-making disc 23 become larger and increased trend.
The characteristic is indicated graphically in Figure 15.Horizontal axis is the rotation angle from freezing cold handle 25, and left end is " system shown in Figure 11
Ice-like state ", right end are " to terminate state from ice " shown in Figure 14.
The longitudinal axis, which is shown, is applied to the torque from freezing cold handle 25 when carrying out from ice operation, and " spring force (0) " shows " ice making shape
Rotating torques caused by torsion-coil spring 23d under state ".
In Figure 15, shown in solid is that driving gear 24c and driven gear 24d is spur gear, has certain number of teeth
Gear mutual engagement the case where.Rotatable handle angle beta 1 under " distortion starts " state is " distortion starts (1) ", will at this time
Handle operation torque be set as " spring force (1) ".
In this case, due to the reduction ratio 1/N between driving gear 24c and driven gear 24d0=1/ (R20/R10) always
It is constant, so the operation torque from freezing cold handle 25 has trend identical with the rotary load torque of ice-making disc 23.Herein, in structure
As if making to rotate about 100 ° of β 1=from freezing cold handle 25 until 23 rotational angle β 3 of ice-making disc is (about if " terminating state from ice "
190 °) in the case where, reduction ratio 1/N0=1/ (100/190)=1/0.53 and become constant, from " ice-make condition " to " distortion
Start " state position is the structure accelerated to driven gear 24d.
During until since " ice-make condition " to " distortion " state, Torsion coil only can be applied to ice-making disc 23
Rotating torques caused by spring 23d, to substantially linearly increase before " spring force (1) " at " distortion starts (1) "
Add.
Since " (1) distortion " state until " terminating state from ice ", if operating from freezing cold handle 25, ice-making disc
23 distortions, to apply the distortion torque for adding ice-making disc 23 other than the rotating torques caused by the torsion-coil spring 23d
" from ice torque (1) " afterwards.
Since the maximum value of the operating force from freezing cold handle 25 is in " terminating state from ice ", at or near, so to it
It is illustrated.
If near " terminating state from ice ", ice is detached from from ice making unit 23a in operating from ice, then handle operation turns
Square the moment reduce, later only apply make torsion-coil spring 23d and from ice after ice-making disc 23 rotate required for
Rotating torques.
In this way, since " state distortion " until " terminating state from ice ", due to the rotation angle with ice-making disc 23
Increase and rotary load torque increase, so in order to drive from ice the power from freezing cold handle 25 also to have with from freezing cold handle
25 are about rotating 100 ° and increased trend until from " ice-make condition " to " terminating state from ice ", maximum value is in " from ice
Near end state " or " terminating state from ice ".
In Figure 15, dotted line be driving gear 24c and driven gear 24d be helical gear, i.e. reduction ratio (speed-up ratio) with
Rotation and the case where the gear mutual engagement changed.
From rotation angle from freezing cold handle 25 of the ice-make condition until terminating state from ice and spur gear shown in solid
The case where it is identical.That is, (about 180 ° extremely by 23 rotational angle β 3 of ice-making disc if making from freezing cold 25 rotation β 1 (about 100 °) of handle
190°)。
The rotation angle from freezing cold handle 25 until since " ice-make condition " to " distortion " state is set as " distortion
(2) ", and " spring force (2) " will be set as from the operation torque of freezing cold handle 25 at this time.
Reduction ratio (speed-up ratio) at this time is the first reduction ratio 1/N=(R2/R1), with (the R2 in the case where spur gear0/
R10) compare, R2 < R20, R1 > R10, thus N < N0, the rotation of the ice-making disc 23 relative to the rotation angle from freezing cold handle 25
Angle is larger.
Therefore, become " distortion starts (2) " < " distortion starts (1) ".On the other hand, produced by torsion-coil spring 23d
Distortion torque be amplified to (R1/R2) as the operating force from freezing cold handle 25, so that handle when " distortion starts (2) " operates
Torque becomes " spring force (2) ", and the relationship with " spring force (2) " > " spring force (1) ".
On the other hand, since " (2) distortion " until " terminating state from ice ", the denominator N of reduction ratio (speed-up ratio)
Increase with rotation, so that the ratio of the rotation angle of ice-making disc 23 and rotatable handle angle is reduced, on the contrary, ice-making disc 23
The ratios of rotating torques and rotating torques from freezing cold handle 25 increase.That is, under " terminating state from ice " from freezing cold handle 25
It is smaller than " from ice torque (1) " to operate torque " from ice torque (2) ".
In addition, become " terminating state from ice " before, by the ice in ice-making disc 23 from ice making unit 23a remove carry out from
Ice, to be reduced from the handle operation torque after ice, it is only necessary to make turning for the ice-making disc 23 of torsion-coil spring 23d and sky distortion
Square.
As described above, torque capacity required for operating from ice is about near " terminating state from ice ", thus with drive
The case where moving gear 24c with driven gear 24d is spur gear is compared, and a side of helical gear is applied to when carrying out from ice from ice
The maximum value of the power of handle 25 is smaller, is able to suppress the increase of operation torque, so as to provide it is reliable from ice, using letter
Just and easy ice maker 20 is operated.
In the present embodiment, near after since " ice-make condition " from ice operation, rotate ice-making disc 23 negative
