In addition, under the situation after on evaporation tube 14 being welded to the above-mentioned metallic plate 12a that bends to cross section コ font, with this metallic plate 12a, insulating barrier 12b and each heater H 1～HN thermo-compressed, owing under high-temperature and high-pressure conditions, carry out as described above, cause evaporation tube 14 to separate so scolder can melt or deform etc., thereby can not realize welding.With respect to this, in an embodiment, be to be bent to form the ice-making component 11 that obtains by thermo-compressed metallic plate 12a, insulating barrier 12b and each heater H 1～HN, again evaporation tube 14 is welded on the metallic plate 12a afterwards, so, solder fusing can not take place and evaporation tube 14 is separated or the situation of distortion etc.Here, adopted the polyimides that under the required high temperature (about 220 ℃) of welding, does not go bad as above-mentioned insulating barrier 12b, so, after ice-making component 11 is made duplexer, even under situation about evaporation tube 14 being welded on this ice-making component 11, insulating barrier 12b or heater H 1～HN can not peel off from metallic plate 12a yet, can not produce the gap that hinders the ice making running at each parts 12a, 12b, H1～HN place.
After the ice making running beginning of the downward flow type automatic ice maker of embodiment, above-mentioned each ice-making component 11 (ice making sheets 10) carries out heat exchange and is forced to cooling off with the cold-producing medium of circulation evaporation tube 14 in, and (the ice making water on the heater H 1～HN) begins to freeze gradually to be fed into the plate-like body 11a of ice-making component 11 via circulating pump PM from above-mentioned ice making water tank 20.Here, owing to above-mentioned ice making water flows down on the surface (ice making face) of the 1st～the N heater H 1～HN of above-mentioned each ice-making component 11, so ice making water freezes on the surface of each heater H 1～HN and generates ice cube M.The ice making water that freezes and fall from ice making face is recycled in the ice making water tank 20 via the through hole of above-mentioned guided plate 18, supplies with to ice making sheets 10 once more.
When detecting finishing ice-making by not shown finishing ice-making testing agency, the ice making running stops, deicing running beginning.When being converted to the deicing running, the closed and charging contactor CC closure of switch SW in above-mentioned control circuit, above-mentioned capacitor CAP is recharged.When being charged to assigned voltage, above-mentioned charging contactor CC disconnects.Then, the 1st discharge is led to 1 heating of the 1st heater H 1, the 1 heater H with contactor DC1 closure, the electricity that is charged among the capacitor CAP.Here, in closure above-mentioned the 1st discharge during with contactor DC1, the electric current that is charged among the capacitor CAP leads to above-mentioned the 1st heater H 1 quickly, this heater H 1 moment heating.Thus, melt at the interface of the ice cube M that freezes on the 1st heater H 1 surface, and this ice cube M is stored in the holder 16 by the deadweight disengaging.Here, in an embodiment above-mentioned ice-making component 11 is made to become the three-layer structure of metallic plate 12a, insulating barrier 12b and heater H 1～HN, so, when using contactor DC1 via above-mentioned the 1st discharge to 1 energising of the 1st heater H, can be to metallic plate 12a or other heater H 2～HN energising.Therefore, to the energising of the 1st heater H 1 time, only make the ice making zone A (ice-making component 11) corresponding with the 1st heater H 1 go up the ice cube M that freezes and melt and break away from, the ice cube M that freezes at other ice making zone A then can not melt disengaging.
And when not shown deicing detection of end mechanism detected ice cube M and fallen fully from the ice-making component 11 of the ice making zone A corresponding with above-mentioned the 1st heater 11, above-mentioned the 1st discharge disconnected with contactor DC1.As long as ice-making component 11 reaches more than 0 ℃ with the temperature of the icing face of ice cube M, ice cube M will break away from, so, if the mechanism of the temperature of employing detection ice making face as deicing detection of end mechanism, then can carry out stable deicing control.Then, once more to capacitor CAP charging, when being charged to assigned voltage, this charging disconnects with contactor CC same as described abovely with contactor CC is closed in above-mentioned charging, and charging finishes.Then, the 2nd discharge makes the electric current that is charged to capacitor CAP to the 2nd heater H 2 with contactor DC2 closure, heats the 2nd heater H 2 and ice cube M is melted from the ice making zone A of correspondence break away from and be stored into the holder 16.Like this, utilize the electricity be charged among the capacitor CAP to switch on successively and stop energising up to N heater H N, deicing detection of end mechanism detects ice cube M when the ice making zone A of correspondence breaks away from, and the deicing running finishes and is transformed into the ice making running.
Like this, constitute above-mentioned ice making sheets 10 by a plurality of ice-making components 11 independently, on each ice-making component 11, mark off ice making zone A, and, in each ice making zone A (ice-making component 11), the 1st～the N heater H 1～HN is set independently, thus, even once all generating on all ice-making components 11 under the situation of ice cube M, the ice cube M that freezes in specific ice making zone A (ice-making component 11) is melted break away from by the ice making running.Promptly, only make its heating and ice cube M is broken away to heater H 1～HN energising corresponding to regulation ice making zone A, successively the heater H 1～HN corresponding with other ice making zone A switched on afterwards, can suppress to make ice cube M to melt thus and break away from required heat from an ice making zone A.Therefore, do not require that heater H 1～HN or distribution, discharge possess special hear resistance with parts such as contactor DC1～DCN, can reduce the cost of ice machine.In addition, be to break away from by making its heating that ice cube M is melted to each heater H 1～HN energising, thereby can shorten the deicing running and need not deicing water, so, can reduce operating cost, and, can increase the manufacture of ice cube M in the unit interval, the advantage of the ice making capacity that can improve ice machine is arranged.
In addition, when deicing is turned round, above-mentioned each heater H 1～HN moment is generated heat, only melt ice cube M and interface portion each heater H 1～HN, under thus can be when the deicing low state ice cube is broken away from short notice from ice making zone A at the internal temperature of ice cube M.Therefore, can under low-temperature condition, ice cube M be stored in the holder 16.If the deicing time takes a long time, thereby then might ice cube M except that with the interface of heater H 1～HN the position also melt and in holder 16, freeze again and form the ice cube M of distortion, but the interface of in the downward flow type automatic ice maker of present embodiment, only melting ice cube M, so can prevent such unfavorable condition.
; under the situation that ice cube under the lower state of the internal temperature of ice cube M breaks away from from ice making zone A, temporarily (the ice cube M that the surface of heater H 1～HN) breaks away from falls the way once more in the ice-making component 11 (possibility that the surface of heater H 1～HN) freezes at it from ice-making component 11 in existence as described above.Given this, in the downward flow type automatic ice maker of embodiment, with from the below along with the mode that towards the top and forwards tilts disposes each ice-making component 11, so, temporarily (the ice cube M that the surface of heater H 1～HN) separates leaves ice-making component 11 along with falling, prevented once more in the ice-making component 11 (situation of freezing on the surface of heater H 1～HN) from ice-making component 11.In addition, owing to constitute above-mentioned biside plate 11b, the 11b of above-mentioned each ice-making component 11 along with the mode of leaving towards the place ahead, so ice cube M can leave from each side plate 11b, 11b along with falling also, can also prevent the situation that this ice cube M freezes on side plate 11b, 11b.In addition, by with side plate 11b, 11b's and plate-like body 11a between crooked position form the shape that has circular arc, thereby when melting at the interface of ice cube M, (surface of heater H 1～HN) breaks away from from ice-making component 11 rapidly can to make this ice cube M.
[variation of embodiment]
As automatic ice maker of the present invention, be not limited to the above embodiments, can carry out various changes.For example, be in an embodiment after ice cube is broken away from from an ice-making component, ice cube is broken away from from next ice-making component, but also can ice cube be broken away from the unit of a plurality of ice-making components with this unit as an ice making zone.In addition, though be the control of respectively heating arrangements that is configured in each ice making zone being switched on and stopping to switch in an embodiment, but the also control that can switch on and stop to switch on this heating arrangements by required group unit makes to melt with this ice cube that is energized the corresponding ice making zone of the heating arrangements of control to break away from.In addition, be to constitute ice making unit in an embodiment by a plurality of ice-making components, in each ice-making component, mark off the ice making zone, but also can be shown in Fig. 5 (a) like that, by the crooked ice making unit 10 that constitutes by single plate member repeatedly a plurality of ice makings zone A is set, perhaps such shown in Fig. 5 (b), on the ice making unit 10 that constitutes by plate member, the parallel upright a plurality of wall components 38 of establishing in broad ways devices spaced apart ground, a plurality of ice makings zone A is set thus, and in each ice making zone A, heating arrangements H1～HN is set independently.
In addition, in an embodiment, ice cube is broken away from from an ice making zone, ice cube is broken away from from other ice making zone, make ice cube after all ice making zones break away from, switch to the ice making running, but also can generate ice cube successively from the ice making zone that deicing finishes.In addition, also can constitute can be from outside Visual Confirmation ice making unit, in this case, can obtain bandwagon effect, promptly, can make the observer that observes ice making unit feel inconceivable to once carrying out ice making running and deicing this two opposite operations that turn round, and, can win observer's good opinion by the displaying that ice cube is broken away from accordance with regulations in proper order.At this moment, under the situation of the heating arrangements of STOCHASTIC CONTROL energising, ice cube breaks away from from ice making unit randomly, so have following advantage: can cause the care of observer to the ice cube that next will break away from.
In the ice machine of embodiment, ice making unit constitutes the form that angle in accordance with regulations forwards tilts, but also ice making unit can be configured to vertical form.In this case, as long as will set longlyer, get final product and make the ice cube that temporarily breaks away from can during falling the way, not freeze in ice making unit once more from ice making unit to the conduction time of heating arrangements.In addition,, be not limited to the plate-like body of ice making unit and side plate along with the formation that expands out towards leading section based on identical reason, and with the crooked position of plate-like body and side plate in accordance with regulations radius form the formation of the shape that has circular arc.As implementing automatic ice maker of the present invention, enumerated the downward flow type automatic ice maker, but be not limited to this, also can be ice making water is supplied in the ice making cell that marks off in ice making unit and to form the type of ice cube, so long as a plurality of ice makings zone is set in ice making unit and in each ice making zone, heating arrangements is set independently, then can be existing known various automatic ice makers.
