Description

Ice maker

The present invention relates to a kind of ice maker, be used for refrigerating appliance, especially the family expenses refrigerating appliance has and can and be suspended on the tray in the framework around a swing with twisting.By DE 4,113 767 A1 a kind of such ice maker is disclosed for example.The tray of this tradition ice maker is called at this at the horizontal level priming petock and freezes the position, after freezing, it is swung to demoulding position, and in this position, its upside points to downwards.Distolateral and the opposed projection on distolateral of the tray that acts on through oscillatory gearing mechanism first is pushed up in this demoulding position on the backstop of framework, and this tray can distortion or distortion after arriving demoulding position, and thus, the ice cube that is present in its lattice is discharged from.In order to make tray distortion possibly need a significant torque, because be included in the rigidity that ice in the lattice has increased tray.Correspondingly must make the motor size that drives the tray motion big.This motor spends huge and requires and takies the position in the refrigerating appliance, has lost the refrigeration thing that is used for and has stacked the space.

Task of the present invention is, a kind of ice maker is provided, wherein, little driving torque be enough to make reliably process and the demoulding.

The solution of this task is; For a kind of ice maker; Having at least one can and be suspended on the tray in the framework around a swing with twisting, and this tray is coupling on the drive unit through a transmission device, and this transmission device has the gearratio according to change in location.Can be reduced to through this transmission device and to drive oscillating motion and for making poor between the required torque of tray distortion.Therefore, for the highest torque that applies of the demoulding is compared and can be reduced with the driving force on the axle that acts directly on tray, and must not increase the rotating distance that drive unit is passed by.

Preferred this transmission device is the transmission device of an inhomogeneous speed change, for example four interlinkage transmission devices etc.

If the maximum torque that applies is reduced to a value, this value can not had difficultly with little strength by the user yet and applies, and then motor can be with replacing through manual manual driving device.This has not only practiced thrift significant cost, and has saved the position in the refrigerating appliance.

In the position that makes the tray distortion of transmission device, gearratio should be than high in non-warping position.

Also advantageously, gearratio increases along with the increase of the distortion of tray, so that keep little for the required torque of distortion on the drive unit.

According to first preferred version, the transmission device of ice maker can comprise a lever, and this lever can be in the contacting of transmission power with respect to the axle swing of the swinging axle of tray dislocation and with a surface of tray around one.

Hand operated portion can be the free end of lever.

The free degree that rotatablely moves of lever so that the user is easy on drive unit, apply required rotation, needn't be changed hand preferably less than the free degree that rotatablely moves of tray during this period.The little freedom of motion of lever also can make the simple structure of the housing of ice maker, because do not need big, influence housing aperture stability, that lever can move therein.

If ice maker is square basically or is box-like, the freedom of motion of hand operated portion can meet the destination and only be confined to this box or square upside.This makes can cosily operate ice maker through catching from above.In addition and can be fast and the demoulding cosily, its mode be, the side that the user is supported on ice maker with the thumb of a hand is along last, with all the other fingers catch hand operated portion and towards this side along drawing.

Preferred this receipts operating portion is accommodated in the depression on the upside of ice maker; Through avoiding making hand operated portion exceed this shape square or box-like, can easily ice maker be placed in the refrigerating appliance.Like this, ice maker for example can directly be contained in an inner horizontal surface below of refrigerating appliance, for example end face below; Refrigeration thing shelf below or horizontal evaporator below; Perhaps, if ice maker can freely be placed, can say other refrigeration thing stacking above that in refrigerating appliance.

The changeability of gearratio especially can realize thus: lever can radial motion on the surface of tray with the contact point on surface.This contact point when on tray, applying high torque (HT) when applying low torque the axle from tray leave fartherly; Can make through this and to hold very for a short time trying hard to keep of contact point effect, this has reduced the demands for bearing capacity of butt contact and can have been avoided the fretting wear between lever and the surface.

According to second preferred version, transmission device comprises wheel interact with each other or wheel section, and they have complementary non-circular basic circle.The shape that especially can have spiral of Archimedes of basic circle.

Be used to collect the downside that the collection container of processing also preferably removably is fixed on framework.If collection container is on its position, the ice cube of then when the demoulding, extruding from tray can directly fall into; If but lacked the position in the refrigerating appliance, this ice maker also could use under the situation of collection container not having.

The upside of framework meets the destination and carries a lid.This lid stops water vapour from tray diffusion and prevent undesirable frosting thus around ice maker.

If in this lid, form the depression of a draining in tray, then can not remove lid and to the tray priming petock.

Ice maker preferably has the measuring vessel that can take out, and the capacity of this measuring vessel is equivalent to integer/one of capacity of capacity or said at least one tray of said at least one tray.Use this measuring vessel to pour into tray through the user, can guarantee, tray is poured the correct water yield, even when perfusion, can not see the lattice of tray or can't see all lattice.

Preferred especially this ice maker can be used in the family expenses refrigerating appliance and move.

Other features and advantages of the present invention are learnt from following specification and the embodiment with reference to accompanying drawing.Accompanying drawing illustrates:

The ice maker shown in Fig. 1 and 2 have one square basically, open wide at upside and downside, with the framework 1 of injection molding.The upside that opens wide of one lid, 2 these frameworks 1 of sealing, this lid has two walls 3,4 from top embedding framework 1, in these walls, maintains bearing, be used between wall 3,4, extending, can be around the tray 5 swung at the vertical upwardly extending axle of ice maker.This tray 5 with the elastoplast injection mo(u)lding is separated into a plurality of lattice 6 in known manner, and these lattice are provided for holding the water that will freeze.Partition between these lattice 6 also with mode known, that do not describe here above that seamed edge be provided with breach so that in case in lattice 6 the horizontal plane minimum point that surpasses breach that rises just allow to overflow to adjacent lattice from these lattice 6.The specified groundwater increment of tray 5 is definite like this: make all lattice 6 be interconnected through breach.

Above tray 5, in lid 2, embed a tank 7.The flow export 8 of this tank 7 stops above the lattice 6 of tray 5, makes the water that injects tank 7 reach lattice 6 reliably.This flow export 6 can have a plurality of apertures above different lattice 6, to guarantee that water flows out swimmingly.The cross section in each aperture is less than the cross section with lattice 6 interconnective breach, and making can be than not fast to the speed of adjacent lattice effusion through breach through the speed of one of these apertures inflow water.Guarantee that thus as long as the water yield of injecting is no more than the capacity of tray, tray 5 just can not overflow.

Replace discrete, respectively feed an aperture in the single lattice 6, flow export also can be configured to the slot that above a plurality of lattice 6, extends.Its advantage is to have reduced to be frozen in the probability of the water slug in the flow export.

Be adjacent to be provided with a depression 9 with tank 7, in this depression, settled a slide plate 10 at the upside of lid 2.This slide plate is used to make tray 5 swings and distortion, and illustrated in detail is also wanted in the back.This slide plate does not exceed the upside of lid at it in the resting position shown in Fig. 1 and 2.

In depression 9 with cover and form a vacancy portion 12 between 2 the leading edge 11, it is provided for holding measuring cup 13.Except a hand is scratched groove 14; The shape of vacancy portion 12 to a great extent with the shape complementarity of measuring cup 13; So that without measuring cup the time, can shape hold this measuring cup sealedly; This hand is scratched groove and is reserved from leading edge 11, so that the user is easy to catch the sidewall 15 of measuring cup 13 when measuring cup 13 is arranged in this vacancy portion 12.

The capacity of measuring cup 13 is corresponding to the capacity of tray 5.Therefore, for to tray 5 priming petocks, disposablely accurately pour into measuring cup 13 and make it just enough to tank 7 emptyings.

In order to save the position, also can expect, be n/one of the volume of tray 5 with the volume settings of measuring cup 13, wherein n is a little natural number.Like this, just must be in order to pour into tray 5 with measuring cup 13 perfusions n time and to tank 7 emptyings.

Framework 1 comprises two longitudinal walls 16, a rear wall 17 and an end wall 18, and in the time of in ice maker is packed refrigerating appliance into, this end wall surface is to the door of refrigerating appliance.Outwards the bar 19 of some outstanding levels forms a bearing-surface for lid 2 on the top edge of longitudinal wall 16.Make progress and the concave surface that opens wide forward 20 and the downward hollow leading edge that opens wide 11 that covers 2 of end wall 18 replenish vacancy portions that side is recessed of formation each other; In this vacancy portion; The user can catch the whole ice making device and it is pulled out from refrigerating appliance or can lid 2 be lifted from the ice maker of pulling out; Its mode is that he acts on the edge 11 through concave surface 20 from following.

Profiled piece 21 that the cross section is c-shaped in moulding on the lower limb of each longitudinal wall 16.These some opposed facing grooves of profiled piece 21 gauges.This C shape profiled piece 21 or its groove are determined size and are used for holding movably some bars 22, and these are molded on the top edge of sidewall 23 of the collection container 24 that is box-like basically.

Fig. 3 illustrates the three-dimensional view of a refrigerating appliance such as domestic refrigerator, and this refrigerating appliance is equipped with above-mentioned ice maker.A storage chamber of this refrigerator is divided into a plurality of lattice 25 with common mode, wherein be in top lattice can be respectively through 26 sealings of a valve, pull out box 27 and can place in the lattice 25 below.One of valve 26 illustrates with open position, is placed with ice maker 28 at the lattice 25 that are arranged in its back.On the end face 29 of lattice 25, be fixed with two L shaped profiled pieces 30 that on depth direction, extend, one of them is hidden by ice maker 28 in the view of Fig. 3.The horizontal leg of two L shaped profiled pieces 30 forms bearing-surface, and the bar 19 of framework 1 is being bearing on these bearing-surfaces on the depth direction movably.In the grasping shell 31 that the user forms through the leading edge 11 of stretching out one's hand by concave surface 20 and lid 2; Can the ice maker 28 of kayser in the stop dog position that pushes be drawn forward through overcoming little resistance, take out measuring cup 13, operation slide plate 10 or surely so that can look ice maker how far be drawn out to tank 7 water fillings.

Collection container 24 is provided with grasping vacancy portion 32 at its downside.It slides on L shaped profiled piece 30 than whole ice making device 28 in the C of framework 1 shape profiled piece 21 more easily, makes that framework 1 keeps static when drawing collection container 24.

Ice maker 28 can be used as whole by L shaped profiled piece 30 gauges, make it time spent not stackable outside refrigerator and the position that discharges thus can use it for anything else.Because

bar

19 and 22 is measure-alike, also has such possibility: collection container 24 directly and individually is suspended on the L shaped profiled piece 30.Like this, can be through only framework 1 and lid 2 being taken out the major part that discharges the position that in lattice 25, is occupied by ice maker 28, the ice cube of processing certainly also occupies the fixed position at collection container 24.

Certainly, ice maker 28 also can freely be placed in one of lattice 25 or pull out in one of box 27.Especially can expect that tell lattice in the box in order to be placed in to pull out in the box and pull out at this, this lattice shape is held ice maker sealedly and when on slide plate 10, applying power for the demoulding, ice maker supported.

Fig. 4 illustrates the schematic cross section of ice maker 28 along a plane, and extend in the depression 9 of transversely passing of the swinging axle of tray 5 on this plane.See that at this slide plate 10 is parts of a single-arm lever 33, this lever can extend with respect to axle 35 swings of the swinging axle 34 of tray 5 skew downwards abreast and the slit 36 passed on the bottom of depression 9 around one.Two axles 34,35 are fixed on the wall 4 that extends between tray 5 and the lever 33.This lever 33 is shown in two positions, and resting position that is tilted to the right and one is the position of swing left for the demoulding, and in this resting position, lever abuts on the backstop on 36 right parts, slit.Correspondingly, tray 5 is also shown in two positions, the freezing the position and freeze the inverse position clockwise with respect to this and swing about 150 ° demoulding position of level.Tray 5 is loaded to freezing locality through unshowned spring.

The distolateral bearing pin 46 of giving prominence in the direction of axle 34 in the face of the observer from tray 5 is supported on the side edge 47 of lever 30.When this lever when resting position is swung left, it drives the oscillating motion of trays 5 through bearing pin 46, this moment, bearing pin 46 moved on a circular arc shown in broken lines.Contact point between bearing pin 46 and the lever 30 moves forward from axle 35 along 46 along side earlier in this motion process, after lever 30 is through the upright position, returns to the direction of axle 35.

Ran into from wall 3 outstanding 39 last times of backstop when the projection 48 on observer distolateral of deviating from of tray 5, the oscillating motion of tray 5 finishes.At this moment, bearing pin 46 leave lever 30 with respect to the directed basically diametrically side of axle 35 along 47 and to be ready carrying out the transition to the second side along on 49, this edge, second side and side launch an obtuse angle along 47.The deviation of the circle that the direction of side along 49 and drawn around axle 35 is more little, and is more little through tray 5 distortions that the rotation that gives lever 30 reaches, and is to reach that to reverse required torque also more little.Side can adapt to the steepness of tray 5 like this along 49 direction: the power that makes the user must be applied on the slide plate 10 in order to make tray 5 distortions is not obvious greater than being the required power of swing before.

Fig. 5 is to illustrate the alternative plan of ice maker with the similar section of Fig. 4.Bearing pin 46 is replaced by the wing 37 at this, and this wing is on the axial direction, promptly transverse to diagram plane crossing wall 4 towards wall 4 distolateral in other words towards the observer and extend and keep being pressed on the convex shoulder 38 of lever 33 through back-moving spring above-mentioned from tray.

If the user is with lever 33 swing counterclockwise, then convex shoulder 38 is pressed to the wing 37, and the power of tray 5 against is swung in the counterclockwise direction.This moment, convex shoulder 38 moved on the track of the circular arc that a with dashed lines is drawn.Convex shoulder 38 further reduces with the distance of swinging axle 34 on first section of this track, and making only needs lever 33 a small amount of deflections to make tray 5 swings far away like this: make the aperture of lattice 6 point to downwards.

Lever 33 in the second place shown in Fig. 5, tray 5 is with respect to freezing about 150 ° of position counter-clockwise swing, tray 5 deviate from lever 33 distolaterally run into a backstop 39, this backstop is outstanding forward from building 2 rear wall 3.If drew in the counterclockwise direction the position shown in lever 33 was crossed, the then distolateral also rotation towards lever 33 of tray 5, convex shoulder 38 outwards slides on the wing 37.The deviating from the distolateral of lever 33 and can not follow this rotation again of tray 5, tray bears the distortion that increases gradually, and through this distortion, the ice cube of processing is extruded from lattice 6.Lever 33 is drawn far more, and convex shoulder 38 is big more with the distance of swinging axle 34, and the torque that the user can be applied on the tray 5 is also big more.Thus, only need little strength can make tray 5 distortions so far: all ice cubes of processing are dished out reliably.Through or lever 33 run on the left part in slit 36 or the top edge 40 that the wing 37 is fallen wall 4, tray 5 accessible distortions are limited to a certain degree, this degree is got rid of plastic deformation reliably.

Fig. 6 illustrate according to third party's case of the present invention with the similar section of Fig. 4.Lever 33 was prevented being connected in this and the first round 50 with reversing, on the part 51 of its circumference, divided tooth although this is taken turns as gear, and here this part 51 does not have round shape, but a spiral of Archimedes.This helix is in about angle of 60 ° of this extend through.The tooth of this circumferential section 51 and one second is taken turns the tooth engagement of a part 53 of 52, and this is taken turns with tray 5 is anti-and is connected with reversing.This part 53 also has the shape of spiral of Archimedes, wherein, and the so mutual coordination of the lift angle of two helixes: make their tooth all keep being meshing with each other in each position.Corresponding to the gearratio between two helixes, much bigger angle of ratio first helix of the second helix extend through, about 180 ° at this.Two wheels 50; 52 form a transmission device; Its gearratio shown in the resting position of lever 33 in other words tray freeze in the position make tray in the starting stage of its motion fast rotational obviously greater than 1, along with the increase gearratio of the deflection of lever 33 is more and more littler; Less than 1, make to apply with a wet finger at last for twisting the required power of tray.
