Summary of the invention

The purpose of this invention is to provide a kind of ice machine, wherein, simplified ice cube the removing from mould that has prepared.

Above-mentioned purpose realizes that through a kind of ice machine said ice machine comprises at least one pallet, and said pallet can be around axis distortion, and the lever that radially extends with respect to said axis is installed in the pallet place.

In order to make lever when not using, not take excessive space, said lever preferably can be received between position and the actuated position location again closing, the distance from the grasping section of lever to said axis when actuated position than close when receiving the position big.

Closing the receipts position, lever does not preferably extend beyond vertical wall of pallet.

Setting movement can be displacement again; Preferably said location again is a pivoting action.

If pallet can particularly remove at icing position and ice around first axle and be installed in pivotally between the position in the framework, then lever preferably can pivot closing second axis of receiving between position and the actuated position around being provided with the first axle parallel offset.Like this, the feasible pallet that both can make pivots, also can it be twisted but continuous motion ground uses lever.

At actuated position, lever is advantageously stoped by the stopper section around the pivoting action of second axis, and lever and pallet can pivot around first axle together.

Lever is advantageously provided the opposite end face place at pallet in the stopper section freely with the pivot of restriction pallet, so that twist said pallet effectively.

According to preferred an improvement, second pallet can pivot around first axle, and lever is arranged between first and second pallets.This can access a kind of compactness and firm structure, and also can make mechanism for ice maker is caused left-right symmetric, thereby no matter said ice machine is to be installed in the door with the left hand suspension or with the mode of right hand suspension, its operability is good equally.

Closing the receipts position, lever can be supported on the axle of pallet, can the quick and grasping reliably by the user thereby be retained.

For approaching and lever easy to use, also advantageously, first pivot axis is directed along the width of the housing of refrigerating plant.

Pallet preferably is divided into a plurality of compartments with known mode own by dividing wall.Anti-sealing spilt when the high 15%-70% of ratio dividing wall of pallet, preferred 30%-40%, the above outer wall of top edge that therefore is projected into dividing wall can comprise under the situation of aqueous water mobile pallet in the compartment of pallet.

Preferably the inboard spill ground at said section is crooked for the section on the dividing wall of extending to of at least one outer wall, rocks water on the outer wall with the continuous roughly mode deflection of laminar motion so that make owing to act on acceleration on the pallet, thereby prevents to spill.

Fill water and remove established ice in order to make it possible to cosily the grasping ice machine, ice machine advantageously is mounted to and can in refrigerating plant, moves.This is suitable especially under the situation of the directed ice machine of pivot axis broad ways, because said ice machine does not occupy the entire depth of the inner space of refrigerating plant usually.

Figure 11 is the decomposition view of refrigerating plant with ice machine of Figure 10.

The specific embodiment

Fig. 1 shows the internal view of refrigerating plant door 14.Door 14 has known structure, and this structure has: by shell 15, the inwall 16 that the plastics deep-drawing forms and the central space that is crossed by shell 15 and inwall 16 that metallic plate forms, said central space is foam-filled by adiabatic plastic resin.Large-area protuberance 17 is formed on inwall 16 places, and said protuberance 17 is bonded in the inner space of refrigerating plant framework when door 14 is in the closed position.Arm 18 is formed on protuberance 17 places in the deep-drawing process of inwall 16, every pair of arm keeps an icemaker tray 1, and said pallet 1 below will be described referring to Fig. 3 in more detail.

In the space of lever 20 between two pallets 1, and be rigidly connected with two pallets 1, locate in the position shown in the figure 1, said lever 20 has been covered the middle arm in three arms 18 to a great extent.Grasp eye or the hook 21 that face on door 14 the free end of lever 20 make and grasp lever 20 and become and be more prone to.

Pin 22 is molded on each end-face wall 5 of lever dorsad 20 of two pallets 1; When user's grasping lever 20 and draw its away from door 14 so that pallet 1 is when passing axis 23 that arm 18 and parallel door 14 extend and rotate to ice cube outflow location as shown in Figure 2, said pin 22 is the corresponding contiguous arm 18 of touching from the below.

At the ice cube outflow location of Fig. 2, the compartment 2 of pallet 1 is transferred to downwards, and the end wall 5 of the lever dorsad 20 of two pallets 1 is stoped on outer arm 18, to prevent any further rotation by the stopper section of pin 22.Through the free end of downward promotion lever 20, the user causes the torsional motion of pallet 1 around axis 23, and makes compartment 2 produce distortion, and then ice cube wherein is extruded.

In order to catch ice cube, container 24 advantageously is being installed in below the pallet 1 on the door 14.Especially, container 24 can be the design the same with door compartment, and said door compartment is installed in another position of the inboard of door, and does not show among the figure.

Icemaker tray 1 is installed in door means on 14, the influence that said pallet is quickened easily and slows down, said acceleration and the aqueous water of deceleration meeting in compartment 2 apply motion, and can cause that under hostile environment said water spills pallet.Especially, after pallet 1 has been filled water, close door 14 the time, the unexpected deceleration during door 14 bump frameworks almost can not be avoided.

In this case, the measure that anti-sealing spills can explain that Fig. 3 shows the cross section of pallet 1 referring to Fig. 3.Two vertical walls 6 and two compartments 2 of pallet 1 are passed in said cross section.Other compartment 2 is in a lateral direction in abutting connection with this cross section.Compartment 2 is separated through dividing wall 3 each other, and said dividing wall 3 is provided with breach 4 in their upper edge, can flow into contiguous compartment from the compartment 2 that is full of through said breach 4 water.Therefore, when keeping flat, the operation water level 13 of pallet is higher than the lower limb of breach 4 a little.

In order more easily to produce frozen ice cube, compartment 2 inboards do not have sharp keen edge, and have the cross section that reduces continuously downwards.Dividing wall 3 and vertical wall 6 or end-face wall 5 carry out the transition to the lower surface 8 of compartment through continuous curved section 7.

The tendency of end-face wall 5 increases continuously from the top to the bottom, and at least above dividing wall 3, end-face wall 5 is vertically extended.On the other hand, vertically wall 6 vertically is being divided into three sections in succession after the portion.At lower curtate 9, the same with end-face wall 5, the gradient of wall increases continuously from bottom to top.Said gradient reaches peak at horizontal edge 10 places, and said horizontal edge 10 extends at the height place of breach 4.Above this edge 10, the central section 11 of adjacency is arranged, said central section 11 does not have the lower curtate 9 of adjacency precipitous.Central section 11 and upper curtate 12 are through continuous curvature and close.In upper curtate 12, sidewall has the tendency of similar lower curtate 9; Even it can inwardly overhang, and is as shown in Figure 3.

When the door 14 of closing stopped suddenly on framework, the path that water level moves marked with Reference numeral 13 ' in Fig. 3.Water can not followed the deceleration of door at once, thereby water level can rise at the left side edge place of compartment 2.The water of the compartment 2 on right side can rise to the top of dividing wall 3, and a part of water is spilled in the compartment 2 in left side.

In the compartment 2 in left side, rock water to the vertical wall 6 in left side and run into the central section that tilts a little relatively at first there.Therefore, said water can suddenly not slow down as door 14, but can make progress deflection continuously.This has reduced the danger that spills.To such an extent as to if the deceleration of pallet 1 water that very obviously rise in vertical wall 6 places in the left side has surpassed the vertically top edge of wall 6 of left side; The upper curtate 12 that overhangs can apply direction motive force to the right to water; Compartment 2 so water can fall back, rather than spill from sidewall 6 tops.

The combined altitudes of central section 11 and upper curtate 12 overflows water effective protection is provided; The combined altitudes of said central section 11 and upper curtate 12 depends on the acceleration of generation and the time that their influence continues; In fact, said combined altitudes equal lower curtate 9 height 1/3rd to 2/3rds.

In the embodiment of Fig. 1 and Fig. 2, pallet 1 Fig. 1 keep flat the position time must keep one section inapparent distance with protuberance 17 so that the free end towards vertical wall 6 of door 14 that surpasses pallet 1 for lever 20 outstanding provides the space.This segment distance is big more, and lever 20 can be long more, and the user is just more little for ice cube is discharged the power that must be applied on the lever 20 from pallet 1.Yet the space between door 14 and the pallet 1 can cause space utilization not enough.

This problem solves through a kind of arrangement shown in Figure 4 of icemaker tray 1.Therefore pallet 1 horizontal location is positioned at a correct position, to be used for ice making.Lever 20 is installed in two spaces between the pallet 1, and said lever 20 can pivot around axis 25, and said axis 25 is parallel with axis 23, and with axis 23 spaced apart segment distances.When closing the receipts position, lever 20 is by touching on axle 26, and said axle 26 extends and connection pallet 1 along axis 23.Grasping section 27 (not illustrating at Fig. 4) on the free end of lever 20 faces door 14, however the not outstanding vertical wall 6 that surpasses towards door of grasping section 27.Keeping flat the position, grasping section 27 is more higher a little than pallet 1, so that grasping section 27 can be comfily by user's grasping.

Fig. 5 shows along the plane between the pallet 1 through the schematic sectional view of the described layout of Fig. 4.At this; Can find out; Be a bit larger tham 90 ° stop position with respect to closing receipts position pivot, the protuberance 28 of lever 20 is run into convex body 29, and said convex body 29 extends facing between the end-face wall 5 each other of pallet; Make lever 20 when pivoting, drive pallet 1 and move together, and axis 23 becomes the shared pivot axis of lever 20 and pallet 1 above stop position.

As the embodiment of Fig. 1 and Fig. 2, at this, the end face away from each other 5 of pallet also is provided with the pin 22 of protrusion.The pin joint of these protrusions is combined in the curved, recessed portion 30 of the arm 18 that supports pallet 1.If the pivoted together of lever 20 and pallet 1 means that pin 22 has arrived the end 31 of recess 30, the further pivot of lever 20 can only carry out through twisting pallet 1 simultaneously.Fig. 6 shows the layout that is in the Fig. 4 under this twisted state.The open side of compartment 2 makes the ice cube that disengages through compartment 2 distortion freedom to drop out compartment downwards down.

Fig. 7 shows a third embodiment in accordance with the invention and similar cutaway view shown in Figure 5.In this embodiment, the end face side 5 that faces each other of two pallets 1 has the crooked groove 32 that faces each other, is placed between the pallet 1 and the lever 20 that is bent to crooked shape equally has the rib 33 that is bonded in the groove 32.Lever 20 can be received between position and the actuated position closing shown in the dotted line along groove 32 and move, at said actuated position, the kayser projection 34 of each rib 33 by kayser in the recess 35 at an end place of groove 32.So that the power that pallet 1 pivots, kayser projection 34 is pushed in the recess 35 through being applied to lever 20, makes pallet 1 pivoted and can be twisted at last, and is as shown in Figure 6.

Such to embodiment shown in Figure 7 like Fig. 4, the isolated side wall 5,6 that the pallet of second embodiment and the 3rd embodiment also can have referring to Fig. 3 description is used as overflowing safeguard procedures.

If other build-in components, for example door compartment are installed in the next-door neighbour top of icemaker tray 1, receive its free end face of position and be difficult to pivot out closing to Fig. 3 of door 14 and lever 20 shown in Figure 4.Fig. 8 shows the 4th embodiment of ice machine with the view of similar Fig. 1, and in said the 4th embodiment, this problem is solved.Lever 20 also is suspended between two pallets 1, and suspends around the axis 25 (Fig. 9) of the pivot axis that is parallel to pallet 1 23.Receive the position closing of Fig. 8, lever 20 is free sagging.

Fig. 9 also shows the cutaway view through the ice machine of Fig. 8 along the plane of extending between the pallet 1.At this, lever 20 also limits through the protuberance 28 of lever 20 with respect to the free degree of the pivoting action of pallet 1, and said protuberance 28 touchings connect the convex body 29 of pallets 1.Yet, the direction of rotation of the pivoting action of the rotation direction of said pivoting action and front embodiment; The upside of pallet 1 is pivoted towards door 14, touches the upside of arm 18 up to pin 22.In this position, in the slit 36 between two containers 37 of lever 20 above being arranged on pallet 1.In this position of describing like Fig. 9 dotted line, through the free end towards door 14 extrusion levers 20, pallet 1 is twisted and ice cube is evicted from.Lever 20 and door between 14 contact or under situation shown in Figure 9 with the slit 36 that is placed between the container 37 in bolster 38 contact limited pallet 1 possibly twist and prevent pallet 1 permanent deformation.

Figure 10 shows the perspective view of ice machine according to a fifth embodiment of the invention.The ice machine of this ice machine and Fig. 8 is similar basically, but pallet 1 do not remain on from the arm of door protrusion, but remains on all around in the framework 39 that said pallet and above and below are opened wide.The ice machine of Figure 10 is provided, and is in the drawing box 40 that is installed in refrigerating plant framework 41, shown in figure 11.Independent compartment 42 is arranged in the leading edge zone of drawing box 40, and ice machine can the mode with form fit be placed on the compartment 42 from the top.At the base portion place of compartment 42, narrow projection 43 crosses big eyelet 44.Projection 43 is used for support frame 39.Eyelet 44 leads in the removable drawer 45 in the front side of drawing box 40.Lever 20 closes at it and receives the position and dangle and enter into the main compartment 47 after being arranged in drawing box 40 above the rear wall 46 of compartment 42.

In order to remove ice cube in the mould from pallet 1; The user can extract drawing box 40 out from framework 41; And the user's dorsad of the pivot rotaring lever 20 that makes progress free end; And the direction to him spurs said lever, contacts with the inclined surface 48 (Figure 10) of framework 39 and pallet 1 begins distortion up to the protuberance 22 of pallet.Ice cube through distortion is evicted from is fallen in the drawer 45 through eyelet 44, thus removable ice cube.
