The described illustration ice machine of Fig. 1 comprises a mold 11, and water is sent to formation ice body in the mold 11 by filling distributor 12, and this filling distributor 12 is connected with solenoid valve 14 by a water supply line 15.Solenoid valve 14 can be connected with the water supply of suitable pressurization successively.Ice machine 10 further comprises a control module 18, and it is positioned at the front of mold 11, and in order to handle ice displacer 20, the water freezing circulation in the mold 11 is shifted out mold once finishing with ice body.Ice displacer 20 has a plurality of radially ejection arms 21, and these ejection arms are rotatable meshing and will ice in mold 11 and transport, and it is broken and fall near the collecting box 24 that these ice are stripped from device 22 strippings.The ice face contact arm 25 of pivotal mounting extends in collecting box 24 tops downwards, with the height of ice body in the detection case 24.Illustrative mold 20 comprises a plurality of dividing plates 28, and these dividing plate horizontal expansions run through this mold 20 to form a plurality of chambeies, form the ice body of respective number in these chambeies.These dividing plates 28 can be formed with a plurality of suitable groove 29 that is communicated with between each chamber, so that allow water to flow to another chamber from a chamber during water is filled cycling.Be understandable that ice body shifting out in mold cavity can become easily, makes ice body pass through displacer 20 and freely discharges in the chamber below heated mold 11.
This control module 18 comprises a motor 30 with an output gear 31, and this motor drive installation is in the periphery of the relatively large gear 32 of side plate 34 fronts of control module 18.This gear 32 drives a vertical camshaft 35 successively, and camshaft 35 drives a central shaft 36 of ice displacer 20 successively.Therefore this vertical camshaft 35 has the opening 37 of a D shape, and this opening holds ices displacer axle 36 with its rotation.Vertical camshaft 35 drives a cam 38, and fingering has a cam face to cam in the art, and this cam face assists the rotation of same leverage 39 response cams 38 to control the location of ice face contact arm 25 in a conventional manner.Therefore leverage 39 comprises a lever arm 40, and this lever arm has a driven surface of cam that cooperates with cam 38, and the rotation of pivot response camshaft 35 is rotated executing agency's 41 pivots that are fixed with contact arm 25 on it.
In order to reduce manufacturing cost, what know is the various parts of making ice machine control module 18 with molded plastics, comprises gear 32, normal direction camshaft 35, lever arm 40 and executing agency 41.Point out as aforementioned, ice raft go out cycle period displacer arm 21 and stripper 22 between occur under the situation that ice blocks, big pressure is added on the driver part by drive motor 30, causes the damaged or broken of plastics driver part easily, and driver part especially comprises gear and/or camshaft.
According to an aspect of the present invention, driven wheel has spline with the normal direction camshaft and is connected, can more effective distribution driving force and fully reduce and break or the risk of unit failure.In illustrative embodiment, gear 32 has the sleeve pipe that extends back 45 at a center, this sleeve pipe forms with the columniform counterbore part 46 of enlarged diameter, and it defines a circular orientation projection 47, and communicates with the small diameter bore 48 that extends through gear 32 front sides.Normal direction camshaft 35 has an end forward that comprises a column part 50, and described column part 50 is positioned at the cylindrical bore part 48 of gear sleeve pipe 45, and outstanding locking leg 51 extends through the small diameter bore 48 of the central authorities of gear 32 forward.This locking leg has the end surface 52 of taper in this example, so that locking leg 51 is drawn close together, and lock tab 54 locking mesh gears 32 front sides of outwards pointing to.
According to the present invention, the cylindrical bore part 46 of gear sleeve pipe 45 and the cylindrical part 50 of normal direction camshaft 35 form with the spline 55,56 of longitudinal extension, circle spacing respectively, are suitable for the transmission engagement of mounted inside and mutual radial load.Therefore spline 55,56 each be all that to have can be the circular or square tooth top 58 and the common V-arrangement of teeth groove 59.Be understandable that the spline of gear 32 and camshaft 35 55,56 is vertically settled to form the relation that is fitted to each other so that the transmission of the radial load that produces along with the rotation of the operation of drive motor 30 and gear 32 to be provided.Necessary is, spline connects and must allow abundant big torque not have the fragmentation of plastics driver part by the transmission of drive unit, and torque can reach 30% or bigger.Under the situation that theory of operation is entirely understood, can think that surf zone that spline 55,56 because of interlock increases has reduced the magnitude of the transmission pressure between gear and the normal direction camshaft, this pressure produces under the high torque (HT) situation, for example, under the situation of the temporary transient obstruction that occurs ice body between a discharge circulation internal cast and the ejection arm.
Be understandable that, though in illustrative embodiment gear 32 drive cam shaft 35, camshaft successively optionally mechanical attachment to displacer axle 36, camshaft 35 can be a complete part of displacer axle 36.For this purpose, the shaft portion that operationally is connected with the displacer axle of institute's reference is meant that mechanical attachment is to displacer axle or the shaft portion that constitutes with its one.
As shown in Figure 5 and Figure 6, an optional embodiment who drives clutch between gear 32 and normal direction camshaft 35 is described, the torque that this driving clutch can improve by the plastics driver part of driver module 18 transmits, wherein, similar to top description parts provide a similar reference number.In this embodiment, normal direction camshaft 35 also has a pair of locking leg 51, this centre bore that locking leg is passed gear 32 place in case with its front side locking engagement.In order between gear 32 and vertical camshaft 35, to transmit torque, the cylindrical drive sleeve pipe 50 of gear 32 is formed with a pair of driving ear 60 that fully oppositely extends back at its end, and the inverted groove near the axial end surface of the camshaft 35 these contacts and locking leg 51 opposite sides becomes embedded assembly relation and locatees.After 35 combinations of gear 32 and camshaft, can see driving that ear 60 is followed the running of CD-ROM drive motor 30 with transmission and camshaft 32 is given in the torque that produces.
In carrying out this embodiment of the present invention, the becket 61 of an annular can be positioned to closely cooperate around the cylindrical drive sleeve pipe 50 of gear 32.Becket 61 preferably is formed from steel and is press fit on the gear sleeve pipe 50, and beyond expectation is finds that this becket 61 has improved that torque between gear 32 and normal direction camshaft 35 transmits and the breakage or the crack phenomenon that have no the plastics driver part.Becket 61 is considered to strengthen driving the transmission that connects and allow the abundant big torque of no parts breakage thus.
According to a further aspect in the invention, the plastics driver part of driver module 18, especially gear 32 and normal direction camshaft 35 are to be made by the material of anti-stress, and this material has further strengthened not having plastic components crack or other breakage by drive control module to the torque transmission of displacer 20.For this reason, in the embodiment of example, the plastics driver part is made by polyamide.This resin can be any suitable polyamide, but nylon resin preferably.The nylon resin that is fit to includes but not limited to that nylon-6 (for example, polycaprolactam), nylon 6/6 (for example, polyethylene (hexamethyleneadipamide)), nylon 6/12 (for example, poly (hexamethylene dodecanediamide)), their copolymer and their mixture.Preferably, polyamide is nylon 6/6 (for example, poly (hexamethylene adipamide)), and it is typically made by the condensation polymer that hexamethylene diamine (hexamethylenediamine) and adipyl acid (adipic acid) are formed.In order further to strengthen the mechanical strength that driver part is made the material polyamide, polyamide especially further comprises a kind of enhancing fill, for example glass fibre.Polyamide can comprise an amount of enhancing fill.For example, when the enhancing fill was glass fibre, polyamide especially comprised the glass fibre based on about 20% to 30% (for example, about 25%) of resin and enhancing fill gross weight.Commercial resin/the filler mixture that gets comprises, but be not limited to nylon 6/6 resin that provides by the DuPont under the trade mark Zytel, FR50HF NC010 nylon 6/6 resin of Zytel for example, with nylon 6/6 resin that provides by the Solutia under the trade mark VYDYNE, for example VYDYNE909 nylon 6/6 resin.
In order to control the running of ice machine 10 electrical response functions, a kind of surperficial cam circuit 65 is placed in the rear side of the gear 32 of control module 18.As known in the art, surperficial cam circuit 65 as shown in Figure 7, can define a plurality of arc surperficial cam circuit guide rail of conductive material.Gear 32 and surperficial cam circuit 65 from the anticlockwise rotation in zero degree center, order is moved arc guide rail to electrically contact with each contact on the side plate 34 that is installed in module 18, each contact is corresponding to surperficial cam circuit guide rail radial arrangement, with the electric excitation function of operation ice machine.
The water of the ice machine 10 of example is filled the guide rail A that circulates by surperficial cam circuit 65 and is controlled, and water directly is introduced to and fills distributor 12 in order to fill a plurality of chambers of mold 11 in ice machine 10.Be accompanied by the operation of CD-ROM drive motor 30 and the rotation of gear 32, guide rail A is movable to water filling contact 66 and contacts.Surface cam circuit guide rail A radiates the surperficial cam circuit guide rail that ground outwards is provided with most, is counted as water and fills contact 66.Up to now, as mentioned above, for factory such water to be installed and to be filled contact and test water to fill circulation be difficult, this contact is used for filling mold cavity to a predetermined altitude and need not selectivity and adjust the position that water is filled contact.Between the follow-up carrying or installation period of the ice machine in refrigerator/cold storage plant, the installation that water is filled contact also is can be reformed, can cause the unwanted change of water packed height like this.
According to a further aspect in the invention, surface cam circuit guide rail A and water are filled contact 66 can carry out factory's installation and assembling effectively, so that in mold, set up predetermined water packed height, and the water packed height not can by during carrying or carrying ice machine 10 the water that the causes slight change of filling contact 66 axial locations influence.In this case, water is filled contact 66 a general extending structure, this extending structure comprises one first prolongation 68, and this first prolongation 68 has a contact 69 to be parallel to the circumference line direction horizontal expansion that surperficial cam circuit guide rail A crosses the motion of contact 66.Therefore contact 69 has branchs to refer to 70, and along with surperficial cam circuit guide rail A passes through the circular motion of contact, this branch refers to that 70 setover and cooperate with surperficial cam circuit guide rail A.Alternatively, be the brush form when can be understood as contact 66, be parallel to surperficial cam circuit guide rail circular motion line-guiding with similar.In this example, illustrative water is filled contact 66 has one second prolongation 70 lateral offset in first prolongation 68, has a horizontal leg 71 and the control circuit of ice machine to be electrically connected in the mode of knowing at the end of second prolongation 70.
The water of example is filled the recess that contact 66 is positioned in the rear side channel-like of module side plate 34, and it has the opening 72 that runs through side plate 34 and extends in abutting connection with the contact 69 of gear 32 rear sides.First prolongation 68 that water is filled contact 66 can be placed in the channel recess place that is limited by parallel arms 74,75, and formation has and side arm 74,75 biased engagement keep contact 66 to be fixed on side 76 between the side arm.For keep water fill contact 66 correspondence vertical end and therefore keep the axial location of contact 69 with respect to surperficial cam circuit guide rail A, side plate 34 is formed with rib 78,79, the reverse extending end that water is filled contact 66 is adjacent to each other asking of rib 78,79.
At the operation and the gear 32 of ice machine CD-ROM drive motor 30 and during being shown in the rotation of surperficial cam circuit 65 of the original position among Fig. 7, water is filled contact 66 at first will be to close on the spaced relationship setting with gear 32 rear surfaces.The follow-up circumference forward travel of surface cam circuit guide rail A will translational surface cam circuit guide rail A the slope 82 of start-up portion 84 cooperate the branch that causes contact 69 to refer to 70 on the slope 82 that arches up with water filling contact 66, and be forced to start-up portion 84 biased engagement with surperficial cam circuit guide rail A.Because in the embodiment of example, the start-up portion 84 of surperficial cam circuit guide rail A is not electrically connected with the control circuit of ice machine 10, just improving also, the offset contact branch refers to 70 to be slidingly connected with guide rail.
The follow-up circular motion of surface cam circuit guide rail A will produce a slit 85 to move below water is filled contact 66, use the edge 86,88 that limits by slit 85 to clean on fingertip 70 any exogenous impurity of piling up, but this slit 85 is formed between the leading edge 88 of further operation part 89 of the trailing edge 86 of initial rail sections 84 of surperficial cam circuit guide rail A and surperficial cam circuit guide rail A.But the leading edge 88 of the operation part 89 of surface cam circuit guide rail A and water are filled the engagement of contact 66 will closed circuit and effectively encourage and open solenoid water supply valve 14.Solenoid water supply valve 14 stays open state during but water is filled the circular motion of operation part 89 of surperficial cam circuit guide rail A of contact 66 passing, but and is closed by the dead electricity (de-energization) of solenoid valve 14 when the trailing edge 90 of the operation part 89 of surperficial cam circuit guide rail A passes through when exceeding water filling contact 66 along circumference.
According to the present invention, but being designed like this, the leading edge 88 of the operation part 89 of surface cam circuit guide rail A and trailing edge 90 realize that a lasting predetermined filling that repeats circulates, with respect to the axial location of surperficial cam circuit guide rail A slight change is arranged although water is filled contact 69 fills contact prolongation 68-70 by water lengthwise movement, for example may keep the manufacturing tolerance reason of rib 78,79 or contact is stressed between the carrying/carrying of ice machine or installation period is exposed owing to contact.For this reason, but the leading edge of the operation part 89 of surface cam circuit guide rail A and trailing edge are with respect to the rotating shaft radial location of gear and surperficial cam circuit 65, like this, no matter water is filled the slight variation of contact 69 axial locations, the water filling time keeps and continues with unaffected.Because the leading edge 88 of surperficial cam circuit guide rail A and the radial location of trailing edge 90, its available close tolerance forms, and water is filled contact 66 and surperficial cam circuit 65 and can be carried out factory effectively and install and do not need dull and time-consuming Integration Assembly And Checkout program.And, because water fill cycle, just the water filling degree of depth is controlled by the leading edge 88 of surperficial cam circuit guide rail A and the position of trailing edge 90 fully in the mold, fill cycle period at each, mold can be filled into identical predetermined water depth, although the radial position of water filling contact has slight variation during ice machine assembling or carrying.
In sum, as can be seen, ice machine has a simplicity of design, the drive control module of reliable operation more.This module has one and is not subjected to go out driver because of the icecube body blocks the ice raft damaged or that broken phenomenon influences that causes during infusion cycles, although and the water that causes owing to manufacturing tolerance or ice machine ice machine between carrying/carrying or installation period are stressed fills the switch contact position slight variation is arranged, control module is still exercisable to repeat to fill the ice machine mold to identical preassigned.
