Refrigerator

Technical field

The present invention relates to be equipped with the refrigerator of automatic ice maker.

Background technology

As the refrigerator that automatic ice maker is installed, the technology of being put down in writing in the patent documentation 1 (spy opens 2002-174475) is arranged.Disclose following structure in this patent documentation 1: horizontal support has ice making tray in the ice-making compartment of refrigerator, and is disposed at the top of ice bank around the ice machine that is positioned at the axle rotation in the width central authorities and ice is broken away from.In this constitutes, for concentrating on certain in ice bank, the ice that prevents to have broken away from sentences raising ice storage efficient, can carry out just commentaries on classics, the counter-rotating of ice making tray corresponding to the ice storage state in the ice bank.

Promptly, the refrigerator of automatic ice maker is installed, the automatic ice maker that can possess ice making tray by configuration in refrigerating chamber, and supply with a certain amount of water to ice making tray from the water supply bottle of being located at refrigerating chamber, carry out ice making in the ice making tray in being arranged at refrigerating chamber then, the rotation ice making tray comes ice making automatically so that ice falls in the ice chest of being located at its underpart behind finishing ice-making again.

With Figure 14-Figure 18 the problem that above-mentioned prior art exists is described.In automatic ice maker 100, on the ice machine 102 of configuration above the ice chest 101, rotatably be supported with ice making tray 103.This ice making tray 103 turns clockwise as illustrated in fig. 16 so that the ice of making breaks away from.

And, being provided with the inspection ice lever 104 that detects the ice amount that stores in the ice chest 101 in this ice machine 102, this inspection ice lever 104 is located at the rotation side of ice making tray 103 when ice is broken away from, and promptly ice falls side.And constitute in the mode that detects the ice storage amount.Have, above-mentioned ice making tray 103 is disposed at the place of the cold air liberation port (not shown) at the contiguous refrigerating chamber back side again.

Therefore, ice making tray 103 sets by the lining on the depth direction of ice chest 101.In addition, on width, be disposed at the cardinal principle centre of ice chest 101.

Secondly, the control method of above-mentioned automatic ice maker 100 is described with Figure 17.In step 105, supply with the water of scheduled volumes to ice making tray 103 by being disposed at water supply installation (not shown) in the refrigerating chamber.And utilize the cold air that blows out from the cold air liberation port to carry out ice making.

Then, through after the scheduled time, in step 106, detect ice making and whether finish.Particularly, when becoming predetermined temperature, the temperature (not shown) of the sensor that is installed on ice making tray 103 is judged as finishing ice-making when following.

If finishing ice-making then in step 107, detects the ice amount that stores in the ice chest 101 by inspection ice lever 104 by descending.

And, in step 108,, advance to step 109 detecting under the discontented situation of ice storage amount, as shown in figure 16 as the counter-rotating ice making tray make ice break away from action to enter from the ice that ice making tray falls.

If this ice breaks away from release then turns back to step 105 with the action of supplying water.Carrying out these steps by circulation makes automatic ice maker 100 can store the ice of scheduled volume in ice chest 101.

Ice making tray 103 with refrigerator that automatic ice maker is installed of this structure comprises the vertical spaced walls and the horizontal spaced walls that ice making tray 103 longitudinal subdivisions is become 4-5 ice box that is separated into two row vertically.In addition, automatically for example supply with the water about 100cc one time from the water supply bottle that is arranged at refrigerating chamber to this ice making tray 103.

And, because on the feed pipe that this ice making tray 103 is supplied with the water about 100cc is fixed in refrigerating chamber ceiling etc., so but the concentrated area to 1-2 ice box water supply of ice making tray 103.Utilize difference in height that the water of supplying with is assigned in the remaining 6-8 ice box by guide channel (being located at the groove on the spaced walls).In addition, this guide channel is located on the previous longitudinal and transverse spaced walls.

At this moment, have the situation that water does not have the ice box of arrival.This is that promptly the length of the difference in height of water, surface tension, groove, width etc. hinder the factor that flows of water because flow to the resistance that the water of contiguous ice box is yielded to the more little and guide channel of from water supply position difference in height far away more.

And, be equipped with in the refrigerator of automatic ice maker at this kind, as shown in figure 18, ice making tray 103 the insides are equipped with temperature sensor 114.This temperature sensor 114 is to have fixed for example object of thermistor with resin, and it has the elongated pole shape of wide 15mm, thick 10mm, long 40mm.Must guarantee that the temperature sensor 114 that will have this shape is installed on the space of ice making tray 103 the insides.Therefore, the accompanying vertical spaced walls and be formed on the straight line of ice box 117 with wall (the calling inwall in the following text) 117b of ice box 117 opposite sides that are disposed at other row, promptly two inwalls are made into the V font.

Temperature sensor 114 is installed on one usually and shows in 2-4 the scope partly of ice box 117 of 4-5 (all be 8-10).In other words, though 2-4 part ice box 117 in addition needn't be made the V font, all be to make according to the ice box shape of 2-4 part in the past.Have, outer wall 117a makes with reference to the inclination of the inwall 117b of ice box 117 again.

Therefore, if observe, we can say that then it is the ice box that the ice that can make significantly diminishes from the circle that is used to the rotational trajectory that ice broken away from done of as shown in figure 18 ice making tray 103.And temperature sensor 114 is to have by heat-barrier material 115 usefulness mounted apparatus 116 to be installed on object on the ice making tray 103 as shown in the figure.

And the water supply action shown in Figure 17 is certain action of being scheduled to, for the output that provides to ice making tray is provided, for example can not change the duration of runs of supply-water pump.In other words, automatic ice maker is configured to make a certain size ice usually.Therefore, cannot come according to user's needs to make big-and-middle (standard) little ice with ice making tray.

As previously mentioned, because the capacity (capacity of each ice box) of the ice making tray that is provided with in the space of determining is less, so even its size of bigger ice is also received restriction.That is, even can select littler ice, then owing to being very little ice, so, also do not have much meanings even in this ice box, make large, medium and small ice from the ice of limited size.

In addition, exist in when making less ice, because it is big that the difference in height of the water level between each ice box does not become, even can not increase potential energy in each ice box to flowing water so water flows yet, and the surface tension of ice or the resistance of guide channel are dominant, so the water of supplying with from supply-water pump can not flow to the problem each ice box.

Because the ice making tray of existing use in refrigerator automatic ice maker is equipped with temperature sensor between ice box, thus ice box is made the V font, thus make the ice cube of making become chevron, and volume is less and the shape of the ice sold than the market is inferior.

And, owing to can supply with the groove height that water table ratio is provided with on the spaced walls between each ice box, so this slot part becomes with the connecting portion between the made ice of adjacent ice box.Though this connection can be removed from the bump that ice making tray falls when the ice chest by ice, as shown in figure 14, connect the part formation jut 109 that comes off.This jut 109 not only influences the attractive in appearance of ice, also can produce inconvenience when containing ice in the inlet.That is, in existing use-case, there is the problem of making that is formed with big jut on ice.

In addition, the structure that this kind is equipped with the refrigerator of automatic ice maker is: have and rotation drive motor for the ice of making is broken away from from ice making tray, thereby so that ice making tray reverses to transfer to ice is broken away from.Therefore, around ice making tray, guaranteed the space of the rotational trajectory scope of ice making tray rotation.Therefore, this has also limited and has made bigger ice.That is, exist if make and can select the large, medium and small ice making tray iced, then the space that is provided with of automatic ice maker becomes big problem.

Have, if can select the size of icing, output reduces when then making undersized ice, and exists and can not make water flow to all problems of ice box as above-mentioned again.

Summary of the invention

The present invention is the technical scheme that proposes in view of above-mentioned problem.

Promptly, water be equipped with the water supply container that will be provided with in refrigerating chamber in supplies in the ice making tray that is arranged in the refrigerating chamber in the refrigerator with the automatic ice maker that carries out ice making, the present invention is divided into a plurality of row with spaced walls in the vertical with above-mentioned ice making tray, and will be divided into a plurality of ice boxes with horizontal spaced walls by a plurality of row that above-mentioned spaced walls is divided, and being equipped with row with a plurality of row of being divided into above-mentioned ice making tray is the drive division that central shaft is rotated between being listed as with another, the structure that the outer wall of above-mentioned ice box adopts is, join in many places with the circle of doing by the rotational trajectory of the above-mentioned ice making tray that forms around above-mentioned central shaft rotation, and the shape consistent with above-mentioned outer wall shape also made so that above-mentioned ice box becomes polygonal by the wall portion beyond the outer wall of above-mentioned ice box.

In addition, it is characterized in that: the bight that the straight line between the top in the end in the nethermost outside of the above-mentioned ice box of ratio connection and the outside of above-mentioned ice making tray disposes the outer wall of above-mentioned ice making tray more in the outer part.

In addition, it is characterized in that: the circle that above-mentioned bight and above-mentioned rotational trajectory are done joins.

In addition, dispose downwards along the temperature sensor of above-mentioned ice making tray longitudinal extension than the above-mentioned central shaft between above-mentioned row and above-mentioned another row, be formed at planar portions on the above-mentioned outer wall and be the little planar portions of planar portions that forms in the wall portion than the said temperature sensor side of the ice box of the configuration section of the said temperature sensor in above-mentioned a plurality of ice boxes.

In addition, it is characterized in that: be formed with groove on above-mentioned spaced walls and the above-mentioned horizontal spaced walls, the width of this groove is at 6mm or below it.

The present invention is owing to make the shape of ice box become above-mentioned shape, thus can make ice attractive in appearance, even and under the situation that can change output, also can make suitable ice cube.And because the groove between each ice box is less, so even less output also can make water flow to each ice box.Have again, owing to increased the water yield of each ice box, so, for example, output can be changed into large, medium and small to make the ice of the required size of user.

The specific embodiment

To describe the present invention in detail with the embodiment shown in the accompanying drawing below.

Fig. 1 is the longitudinal section of the refrigerator of one embodiment of the present of invention.Refrigerator main body 1 has refrigerating chamber 2, vegetable compartment 3, refrigerating chamber 4 from top to bottom, and the peristome of front is sealed by door respectively.In the present embodiment, the front of refrigerating chamber 2 is covered by revolving refrigerating-chamber door 5.The two fan doors that this refrigerating-chamber door 5 is also split.The front that is positioned at the vegetable compartment 3 of refrigerating chamber 2 belows is covered by the vegetable compartment door 6 of drawer type, and not shown vegetable container together can be pulled out by pulling out this vegetable compartment door 3.Refrigerating chamber door 7 is the door of drawer type with vegetable compartment door 6 equally also, and can pull out not shown refrigerated container by pulling out refrigerating chamber door 7.

Be equipped with automatic ice maker 8 in the refrigerating chamber 4, the below of automatic ice maker 8 disposes the ice chest 9 that stores the ice of making of this automatic ice maker 8.Can store 80-100 blocks of ice cubes of making of automatic ice maker 8 all ice making trays in this ice chest 9.That is, because the ice box of ice making tray is 8-10 a following degree, so the ice of repeatedly being done with automatic ice maker can be stored in the ice chest 9.

The bottle of the ice making tray of automatic ice maker 8 being supplied with the water that is used for ice making is disposed in the refrigerating chamber 2.With mark 10 represented be exactly water supply bottle.Has the capacity that for example can store 1000cc-1200cc water in this water supply bottle 10.Water in this water supply bottle 10 is drawn up by supply-water pump 12, and ice making tray is supplied with by the feed pipe 11 that extends to the ice making tray top in its back side through vegetable compartment 3.The front end 11a of feed pipe 11 is positioned at the top of the ice making tray of automatic ice maker 8, and as following ground, is configured to the water supply lattice towards ice making tray.Have again, during water supply, as following ground, a certain amount of water is supplied with ice making tray.In the present embodiment, duration of runs of supply-water pump 12 for example in 9 seconds the water yield that ice making tray is required for example 100cc supply to ice making tray.

Having, in the present embodiment, though used supply-water pump 12 to be used as water is supplied with the water supply machine of ice making tray, is not to use pump again, can be the water supply machine that the necessary water of ice making can be supplied with ice making tray yet.

Have, refrigerating chamber 7 needn't be covered by Yishanmen again.That is, also can be for example to possess the independently ice-making compartment of cryogenic temperature band is arranged, and cover this ice-making compartment preceding structure by the ice-making compartment door.At this moment, be used as the ice-making compartment door with the door of drawer type, and can be that ice chest 9 also together is drawn out when pulling out the ice-making compartment door structure becomes.In addition, under the situation that is provided with ice chest on the refrigerated container, the refrigerated containers in the refrigerating chamber 4 are divided into two sections, and also can be the ice chest portion ice machine that is positioned at upper container just under locational structure.

Fig. 2 is the perspective illustration of automatic ice maker, has showed the automatic ice maker 8 and the ice chest 9 of automatic ice-making.Automatic ice maker 8 be equipped with built-in CD-ROM drive motor drive division 13, ice making tray 14, and connect the framework 15 of this ice making tray 14 and drive division 13.

The set 14a of bearing portion goes up the chimeric driving shaft 13a that has on one side of ice making tray 14, and projection 14b and framework 15 set on the opposite side edge of ice making tray are chimeric, and ice making tray 14 rotates with the rotation of the CD-ROM drive motor of drive division 13 sides.Be provided with rearward outstanding protuberance 14c with the end of the drive division 13 opposite sides of ice making tray 14, and if this protuberance 14c is designed to that ice making tray 14 is done the rotation of scheduled volume then it offsets with stops 15a on the framework 15 of being located at ice making tray 14 rears.

In other words, though reason CD-ROM drive motor and the ice making tray 14 that rotates have the shape of stopping the rotation when protuberance 14c and stops 15a offset temporarily, the continuation rotation of CD-ROM drive motor can make ice making tray 14 offset at the 14a of bearing portion one side of ice making tray 14 and projection 14b and stops and twist between the side.Ice making tray 14 forms by having flexual material, and makes the ice in the ice making tray 14 peel off from ice making tray 14 by such reversing, and falls ice chest 9 sides.After the rotation that applies scheduled volume by CD-ROM drive motor when falling (that is, ice is broken away from from ice making tray 14, and), make the CD-ROM drive motor counter-rotating, and ice making tray 14 is rotated to than horizontal level be partial to slightly instead from ice motion side.

At this moment, the projection 14b side of ice making tray 14 remains in horizontal level, and the 14a of the bearing portion side of ice making tray 14 from level on the contrary to instead reversing slightly from ice motion side.By so slightly to the instead distortion of reversing the ice making tray that takes place when ice motion side is reversed rectifiable reason ice is broken away from.Thereafter, ice making tray 14 is got back to horizontal level, receives the water supply from the front end 11a of the feed pipe shown in Fig. 1.

With the direction of ice making tray 14, promptly vertically be divided into two row, and be divided into ordered series of numbers, it is divided into a plurality of ice boxes 18 by these vertical spaced walls 16 and horizontal spaced walls 17 with horizontal spaced walls 17 with vertical spaced walls 16 along refrigerator 1 front and back.And, be provided with groove 19 in the spaced walls in length and

breadth

16,17 that each ice box is 18.By this groove 19 with water from other ice boxes 18 of an ice box 18 guiding.When the groove width W of this groove 19 is big, though have effect as the guide channel of water, if be stored in the ice chest integratedly by the ice of a plurality of ice box productions, then inconvenience use.Therefore, in the present embodiment, for example groove width W is set for smaller or equal to 6mm, like this when ice making and when being stored in the ice that disengaging falls in the ice chest 9, the made ice of ice box 18 not with the made ice adhesion of other ice boxes 18.That is, become by when ice breaks away from, putting on reversing of ice making tray 14, and the groove width that each ice is separated of the bump when falling.

If become such groove width, even the water then in the guide channel 19 is when freezing in ice box 18, big connecting portion 109 that also can be as shown in the existing use-case of Figure 14 becomes the less connecting portion that influences outward appearance and influence mouthfeel.

But as above-mentioned prior art, this groove width also can produce owing to make guide channel 19 become resistance with the capillary relation of water with the relation of output, and can not be to the situation of each ice box 18 even water guide.That is, exist the difference in height of the water of supplying with to ice making tray 14 (for example water of 100cc) less, even then can not make the mobile situation of water by guide channel 19.To narrate in the back about this problem.

Fig. 3 supplies water to move for explanation diagrammatically to have showed the figure of outward appearance.As previously mentioned, water is drawn up by supply-water pump 12 from water supply bottle 10, the water that draws up is through supplying water to ice making tray 14 from feed pipe front end 11a in the feed pipe 11.In the stage of receive supplying water, ice making tray 14 keeps level as shown in the figure under the state of sky.

In the present embodiment, water supply bottle 10 is the bottles that can store the water about 1000cc～1500cc, and ice making tray 14 has the structure of the water about 100cc of can packing into.The task of supply-water pump 12 is to carry for example water of 100cc from water supply bottle 10 to ice making tray 14 when carrying out ice making work at every turn.12 work of unshowned control part control supply-water pump are to supply with the water of scheduled volume with supply-water pump 12.That is,, for example in 9 seconds, carry the water of about 100cc with the duration of runs of control part control supply-water pump 12.Therefore, when supplying water, ice making tray 14 all makes supply-water pump 12 work 9 seconds at every turn.

Water by supply-water pump 12 draws up from water supply bottle 10 supplies water to the A of ice making tray 14 one (Fig. 3) via feed pipe front tube 11a by feed pipe 11.This A portion is the part of having showed front tube 11a and being positioned at the ice box 18 of its positive bottom, and the water that falls from front tube 11a is supplied with the ice box 18 in the A portion at first.

And, as shown in the figure, with the cardinal principle top of the position configuration of front tube 11a on the fore-and-aft direction of refrigerator 1 in the horizontal spaced walls 17 of 18 of ice boxes.

If to A portion supply water the water level of this part (ice box 18) shown in the L2 of Fig. 4 as moment rise, so the water conservancy of having supplied with flows to A portion ice box 18 in addition with difference in height as a arrow of Fig. 3.And finally make water levels in all ice boxes 18 of ice making tray 14 reach same water level (though not shown in the figures, but two row ice boxes 18 is whole) by guide channel 19.That is, the guide channel 19 of present embodiment is located on whole horizontal spaced walls 17 with to whole ice box 18 water guides longitudinally.

With Fig. 4 guide channel 19 is described.Fig. 4 be among Fig. 3 P to view.The groove width W that is located at the guide channel 19 on the horizontal spaced walls 17 has showed and the identical object of guiding groove width illustrated in fig. 2.The degree of depth L1 that forms this guide channel 19 carries out water guide to have enough degree of depth with respect to ice box 18.In the present embodiment, be equipped with groove 19 with to 10 ice boxes, 18 even water guides.Therefore, can be to being placed side by side whole water supply of ice box 18 longitudinally.

What in addition, the position of front tube 11a on the width of refrigerator 1 was configured in wherein row (Fig. 4 left side water supply lattice 18) in the ice boxes 18 that are provided with two row on the width just goes up the position.That is,, will supply with row of width at first from the water that the front tube 11a shown in the A portion of Fig. 3 falls according to present embodiment, and from the ice box 18 shown in Fig. 3 A of supplying water of initial quilt of these row by guide channel 19 as Fig. 3 arrow a to each lattice water guide.

Secondly the running of shaking of ice making tray 14 is described with reference to Fig. 5.In the present embodiment,, carried out that ice making tray 14 is tilted and recovery level a succession of shakes action in order to have carried out the equalization of the water level in each ice box 18.Though this shakes action and is finished by the driving of drive division 13, the control when this shakes action with ice disengaging action is equally by not shown control part control.

Fig. 5 has showed the state that the ice making tray 14 that makes in Fig. 4 state rocks from side to side.That is, if the ice making tray 14 in Fig. 4 state is received water supply from feed pipe 11, then at once as tilt as solid line among Fig. 5 or the double dot dash line (shaking).At this moment, the amount of ice making tray 14 inclinations is the angle of inclination that the water in the ice making tray does not overflow.

Because this water level that shakes the ice box 18 that action is initial reception water supply (the water supply lattice 18 in Fig. 4 left side) side is higher, receives the tilting action that ice box 18 sides are higher and opposite side is lower (realization of Fig. 5) that supplies water so become at first.Then this shakes the state that action repeatedly repeats solid line among Fig. 5, double dot dash line.

That is, in the ice making tray 14 that the ice box 18 by two row constitutes, be equipped with under the situation of front tube 11a in the top of a side ice box 18 (Fig. 4 left side), it is that the ice box 18 of an above-mentioned side is uprised and ice box 18 step-downs of opposite side that initial shaking moved.Repeating under this situation of shaking action, for the water level of the ice box that makes both sides is identical, waving angle can be positive and negative identical, and the cycle also can be identical.And, changing under the situation of waving angle, if make and first shake the waving angle maximum of (shaking at first in the shaking among Fig. 5 shown in the solid line) then the efficient height.Even in this case, repeating repeatedly to shake under the situation of action, the final angle of shaking action can be positive and negative identical angle.

Illustrate that with Fig. 8 this shakes action.Fig. 8 is the ice making control flow chart of present embodiment.If ice breaks away from release, and ice making tray 14 keeps level as Fig. 4 as, then in order to carry out ice making thereafter, begins feedwater by step 21 and moves.Here supply with the water of 100cc to ice making tray 14.As previously mentioned, this water supply is to supply with the ice box 18 that limits in the ice making tray 14, so the water reason difference in height of supplying with and move to other ice boxes 18 by guide channel 19.Though repeat this action when existing near the water-head that can overcome the amount of resistance of guide channel 19, in water supply portion ice box 18 far away, flowing stops.

That is, though guide channel 19 utilizes difference in height will make water flow to adjacent ice box 18 from ice box 18, if the resistance that water usually can not overcome guide channel 19 thereby difference in height is less can not flow.

What prevent above situation appearance is following step 22.If feedwater action 21 finishes, then enter the ensuing action of shaking.This shakes and carries out before finishing ice-making 23 as the action as shown in Figure 8, and also as shown in Figure 5, makes ice making tray 14 around axle positive and negative shaking rotatably repeatedly (can be the certain angle or the angle difference of shaking) in predetermined angular at every turn.To set at higher (solid line among Fig. 5) at first towards the front tube 11a of feed pipe 11 side (H side among Fig. 4) when beginning to shake.Its reason is, with the water level (L among Fig. 4) of the corresponding side of front tube 11a as high as the L2.In other words, for the water that does not make this L2 water level overflows the H side is tilted in initial higher mode.

If feed water release in the step 21, then advance to step 22 so that ice making tray 14 shakes action.This time is for example about 1-2 minutes and shake action 4-5 times.This shakes action and is used to make the water of the supply system ice tray 18 to flow all the time.In other words, it is not used to drive out of air bubble in the ice box 18.Therefore can after the end just of supplying water, implement, and in 1-2 minutes short time, finish.

By implementing to shake action, can obtain following effect.As shown in Figure 3, front tube 11a is positioned at the top of spaced walls, and falls on the spaced walls from the water of feed pipe 11.At this moment, because the potential energy of water, splash and be attached to that the situation of part also has beyond the ice box 18 from spaced walls.Because ice making tray 14 is disposed in the storeroom of cryogenic temperature band, so the situation that the water that adheres to freezes in this part also has.But by implementing to shake action, the water of this part falls, and can prevent the freezing of water droplet at ice making tray edge part place.

Secondly according to Fig. 6,7 variation of shaking the water level that action produces is described.Fig. 6 is the interior mobile figure of water of the drawn ice making tray of solid line that Fig. 5 has been described.Fig. 7 is the interior mobile figure of water of the drawn ice making tray of double dot dash line that Fig. 5 has been described.

(a) showed the water level of the ice box 18 after just finishing that supplies water among Fig. 6.Though by this water level and guide channel 19, water flows to ice box 18b side usually, the surface tension of water can not overcome the resistance that guide channel 19 has and become (a) state if the width W size (Fig. 4) of guide channel 19 diminishes.At this moment, if make ice making tray 14 as tilting as (b) then water is flowed and the difference in height as the water level of dotted line is added in the gradient, flow to (solid line water level) ice box 18b side so break through the resistance and the water of guide channel 19.If (solid line water level) ice making tray 14 is got back to original position, then according to same reasons, ice making tray becomes as (c), and water level becomes par.On the contrary, Fig. 7 has showed the state that supplies water to the ice box 18b with the H opposite side.At this moment, as Fig. 7 (b), make with the H opposite side to tilt to uprise.Other explanations are identical with Fig. 6, so omit.

Have again, in the above-described embodiments,, shake ice making tray 14 then so that the water level homogenising is not limited to this though the ice making tray 14 that is in level is supplied water.For example, ice making tray 14 is tilted, under this state, ice making tray is supplied water, also can make ice making tray 14 get back to horizontal level then.That is,, can realize the homogenising of water level by supplying water under the state that ice making tray 14 is tilted.If do like this, then can omit a part of shaking action, and can realize the homogenising of water level at short notice.And, even in water supply, shake the homogenising that action also can realize water level,, can shorten the ice making time by supplying water simultaneously and shaking.

No matter under the sort of situation, so that shake and stop and supply water finishing simultaneously or be later than to supply water to finish (that is, ice making tray 14 is got back to horizontal level), can help the homogenising of water level by controlling.

Get back to the action that Fig. 8 illustrates automatic ice maker 8.

(as Fig. 6, Fig. 7 (c)) begins ice making when water is got back to substantially uniformly state in ice box 18a, the 18b of ice making tray 14.Detect finishing ice-making with step 23 then.This finishing ice-making is detected by aftermentioned ice making tray temperature sensor, if arrive predetermined temperature following (or, if do not pass through the scheduled time after arriving predetermined temperature), then ice making does not finish also to continue ice making again.If finishing ice-making then advance to step 24 moves to the inspection ice action that the ice storage amounts of carrying out in the ice chest 9 detect.Coming not move to ice with step 25 under the full situation of ice storage amount according to this inspection ice the result of the action breaks away from and moves, and ice is stored in the ice making tray 14, thereby and in ice chest 9, advances to step 26 under the discontented situation so that ice making tray 14 counter-rotatings are finished and made ice fall into ice ice chest 9 in to break away from and move.

After breaking away from action, gets back in ice the feedwater action of step 21 once more.

In the automatic ice maker that carries out control flow chart shown in Figure 8, impose to ice making tray 14 that the means of shaking action are the most resultful to be: for example, utilize ice making tray 14 just imposed changes, the CD-ROM drive motor in the drive division 13 of despining action.

That is, after CD-ROM drive motor is finished the ice that is used to make the ice of making to fall from ice making tray 14 and carries out and broken away from action (just changeing), make this ice making tray 14 cross original position slightly again and the derotation of correcting ice making tray transfers to (counter-rotating).Finish the previous CD-ROM drive motor that shakes action and utilized this part of just changeing return motion motion.

In other words, finish the controlling organization that shakes action if be assembled with in the CD-ROM drive motor, and make the running of this controlling organization, then CD-ROM drive motor can not make the inclination of the degree that the water in the ice making tray overflows on the side of just changeing, reverse shake.

Suppose that under the situation that can not utilize this CD-ROM drive motor, also available other means are come ice making tray 14 imposed and shaken action.Importantly, shake action, and in each ice box that ice making tray forms, make the water Rotating with Uniform, then can reach this purpose if the present invention imposes the ice making tray 14 that has supplied water.

Secondly ice making tray 14 shapes of present embodiment are described with Fig. 9-Figure 11.Fig. 9 is the figure that observes the ice making tray 14 of embodiment from the inside, and Figure 10 is the cutaway view of A-A line among Fig. 9, and Figure 11 is the cutaway view of B-B line among Fig. 9.

As shown in Figure 2, dispose a plurality of ice boxes 18 of being divided by vertical spaced walls 16, horizontal spaced walls 17 on the ice making tray 14, in the present embodiment, 10 ice boxes are arranged into two row ground configurations.This ice making tray 14 vertically corresponding to the fore-and-aft direction of refrigerator 1, and the front side of refrigerator 1 is provided with the 14a of bearing portion, it holds the driving shaft 13a of drive division 13 and is that pivot is rotated with this driving shaft 13a.The opposing party's side is provided with projection 14b and protuberance.Be formed with guide channel 19 on the spaced walls that each ice box is 18 to be used for producing as described above the water level of each ice box 18.

Mark 27 shown in Figure 10 and Figure 11 has been showed for making ice break away from the rotational trajectory of the ice making tray 14 when being rotated from ice making tray 14.This rotational trajectory 27 has been showed ice making tray 14 formed maximum rotational trajectories, and in the present embodiment, for example, upper end (T) joins with this rotational trajectory 27 about Figure 10 and ice making tray 14 shown in Figure 11.Other parts of ice making tray 14 and rotational trajectory 27 join or are positioned at the inboard, are not positioned at (because under the situation with the part that is positioned at the outside, the track that this part is described just becomes said rotational trajectory here) in rotational trajectory 27 outsides.

Among the figure, two circles of identical size have been described in ice box 18 rotational trajectory 27 that formerly ice making tray 14 is done, to be used as ice box 18 with the approaching shape of this circle.

That is, the outer wall 28 that constitutes ice box 18 ice box 18 join with rotational trajectory 27 many places bottom and between upper end (T) or approaching, and make ice box 18 become polygonal.Have again, in the present embodiment, from the front end of the outstanding downwards sensor installation portion 31 of ice box 18 or ice box 18 bottom, make that upper end (T) is positioned on the position that pivot equates substantially from about a pivot side far away and ice box 18, and join with rotational trajectory 27, determine ice box 18 shape so that the part of the outer wall 28 of ice box 18 therebetween or a plurality of part join with this rotational trajectory 27.Aspect the relation of the bottom (B) of outer wall 28 sides of ice box 18 and upper end (T), the end of bottom (B) is designed to join with rotational trajectory 27, and has outer wall 28 than end that is positioned at this bottom of connection (B) and the straight line shape more in the outer part between upper end (T).

In other words, ice box 18 approaches hemispherical to enlarge the volume in the ice box 18.Be used for the outer wall 28 of the polygonization that this volume enlarges, the volume that inwall 29 no doubt can enlarge ice box 18, for vertical spaced walls 16, horizontal spaced walls 17 owing to imitated outer wall 28, inwall 29 has the volume that also can enlarge ice box 18 identical shaped with it.

And in the present embodiment, as shown in figure 10, the inboard, bottom of ice box 18 is provided with the sensor installation portion 31 that is used for mounting temperature sensor 30, and this installation portion 31 is designed to join with rotational trajectory 27 or is approaching.Its result, the ice of making all becomes the polyhedral shape (diamond-shaped) the same with ice box 18 bottom surfaces.

Temperature sensor 30 is as existing use-case is illustrated, owing to thermistor is fixed with resin, so have the elongated circular bar-like shape of for example wide 15mm, thick 10mm, long 40mm.And temperature sensor 30 is installed on ice making tray 14 the insides by pressing element 33 by heat-barrier material 32 usefulness as Fig. 9.Have again, be clamped on the mounting bracket 31 by pressing element 33.

The inwall 29 of the ice box 18 that disposes on the position that this temperature sensor 30 is installed compares with the ice box that is disposed at other positions 18, omitted a bight that is polygonal inwall 29, and this has been omitted be roughly linearity ground with section between the last lower corner in bight and connect.Promptly, on inwall 29 parts between the upper end (T) that connects with the bottom of inwall 29 sides of (B) bottom adjacency of outer wall 28 sides and inboard, with other ice boxes (promptly, the ice box that there is not mounting temperature sensor 30) inwall 29 parts relatively, it has the part that section connects with long straight line, and (section of inwall from last several second ice box shown in Figure 9 connects with long straight line, so can be bigger flat shape), and differently on the direction of the internal volume that dwindles ice box 18, be made into relative outer wall 28.Promptly, if polygonal planar portions of other ice boxes that the planar portions of temperature sensor 30 1 sides will be installed, not there be mounting temperature sensor 30 with planar portions that temperature sensor 30 1 sides (being outer wall 28 sides) are not installed and formation is compared, then the latter has less planar portions.

Therefore, in the space of 18 of the ice boxes of the position that temperature sensor 30 is installed, be formed with the space shown in the oblique line shown in Figure 10 portion 34.Utilize the part of this oblique line portion 34 to come sensor installation 30.And this oblique line portion 34 is located at 2-4 lattice parts of ice box 18 as shown in Figure 9.

According to above-mentioned shape, the revolution space ground that can not change existing ice making tray makes ice increase in same space.And, because the shape of ice box 18 approaches circle, so also can provide profile not have the ice of bigger variation even change size.Have again, because the less thick of vertical spaced walls 16 and horizontal spaced walls 17, thus the shortening of 18 of each ice boxes apart from groove, thus the ice making capacity of ice making tray 14 integral body improved.In addition, because the less thick of spaced

walls

16,17, the thickness of groove 19 also diminishes, thus the coupling part of ice diminish, so can provide shape ice neat and attractive in appearance.And the less thick of groove 19 also can make by the suffered resistance force diminishes of the water of this groove 19.Therefore, the water of supply can arrive each ice box 18 easily.Have, the shape of ice is that a part is roughly spherical polyhedron again, is difficult to occur the crack when producing bump so fall ice chest 9, and also can provide ice attractive in appearance when the user uses ice.

For ice making tray 14,, can improve reversing the intensity with weight loading, and can become the thinner ice making tray of thickness by having such shape.Have, owing to be not to be complete hemispheroidal polygonal, so by suppressing the ice making tray whole rigidity, it is necessary by the caused torsional moment of CD-ROM drive motor to suppress to make ice to break away from, and it is bad to prevent that stagnant ice breaks away from again.

The relation of the water level when secondly, the ice of making bulk, standard, fritter being described and the driving time of output and supply-water pump with Figure 12, Figure 13.Figure 12 is the figure of the water level when diagrammatically having showed the ice of making bulk, standard, fritter, and Figure 13 is the figure of relation that has showed the driving time of the output of supplying with ice making tray and supply-water pump.

In the refrigerator that automatic ice maker is installed of present embodiment, main body side panel part (not shown) is provided with the selector switch (not shown) of the water supply time that can control (user's peripheral operation) supply-water pump 12 (Fig. 3), and the user can be as the size of selection as (bulk) (standard) (fritter) of Figure 12 with the ice of automatic ice-making mechanism.Promptly, wish the user under the situation of water ice, fill with water to ice making tray 14 as shown in Figure 12 (bulk), under the situation of hope (standard) ice, inject the water of amount to ice making tray (ice box), wishing under the situation of fritter, injecting a spot of water as (fritter) to ice making tray (ice box).

Water supply time information (information of the size of ice) by this selector switch input is transported to not shown control part, and this control part is according to the driving time of this information control supply-water pump 12.

Be located at the little water level L3 of output that has considered (fritter) applicable to the degree of depth of 18 guide channels 19 of ice box of the large, medium and small water yield, even and set for output more after a little while the water level by 18 of ice boxes difference in height and shake the water level homogenising that action causes and also can make water flow in the degree of depth of 18 of ice boxes.

By so making output variable, do not have under the situation of ice in summer etc., even in the face of being badly in need of the situation of ice, also can select (fritter) to shorten the ice making time, so can provide ice to the user as early as possible.And, even for the user who needs water ice, because the available water of each ice box 18 becomes big, so can output is variable to be selected (bulk) and bigger ice can be provided by making.

Have again, by change the homogenising that waving angle can be realized water level more efficiently with respect to each water level.

Figure 13 is the figure that the ice of above-mentioned for making (fritter) (standard) (bulk) is controlled the driving time of supply-water pump.Not shown control part is controlled the relation of this time and output.Usually, the driving time with supply-water pump changes output pro rata.When making the ice of situation of the present invention (fritter), driving time is made as 6 seconds, output and is made as 70cc, when the ice of production standard size, make supply-water pump work 9 seconds and supply with 100cc water to ice making tray.Have, same consideration drove supply-water pump 12 seconds when the situation of water ice was also iced with production standard again.

In addition, among the application, though the preset amount of the ice that will make of ice making tray 14 be three stages of (fritter) (standard) (bulk) determining water supply time, owing to the driving time of supply-water pump can be changed into a variety of, so the size of the ice that can make is also variable.That is, by the main body side guidance panel, no matter output is multistage or not stage by stage, and the setting by the user all can drive supply-water pump corresponding to the output of its setting in the scope of driving time.

And, though the ice box that has with the ice making tray 14 of variform ware shape shown in Figure 11 diagrammatically has been described in Figure 12, what the shape of ice making tray was natural is 6mm or its following shape of groove width for not forming big connecting portion of guide channel shown in Figure 11 19.

Have, flow (the particularly situation of small ice) of the water between ice box causes by shaking action again.Promptly, because output is less under the situation of small ice, thus the water-head of 18 of each ice boxes also diminish, though shipwreck is to flow to the ice box 18 far away from the water supply position, but the sort ofly shake action by what carry out present embodiment, can make water flow to whole ice box 18.At this moment, need not to be the waving angle same with the situation of water ice.Under the situation of selecting water ice, so be easy to make water to flow to each ice box 18 because output is more.Therefore, can set for:

(A) only under the situation of selecting (fritter), shake action.

(B) under the situation of selecting (fritter) and (standard), shake action.

(C) under the whole circumstances, shake action.

Even under (B) situation (C), waving angle also needn't be identical, can make the situation of the waving angle of (fritter) greater than (standard), also have, and under the situation of shaking of (fritter), the setting that waving angle is diminished etc.Therefore control part can shake action according to being controlled by the information of selector switch input.

Under the situation of the size that can change ice, because the output difference, so, in control flow chart shown in Figure 8, before the step of action 21 that supplies water, need be equipped with the step of " size discrimination of ice " (or output judgement).In this step, judge the size of user with the selected ice of selector switch of main body side.According to the supply water step of action 21 of the judgement in the step of the size discrimination of this ice.Therefore, in the step of shaking action 22, to carry out the above-mentioned action of shaking, can realize the action of shaking corresponding to the size of icing according to the judgement in the step of the size discrimination of icing by control.

And, if not three stages as present embodiment, even then the two-stage and more than the quadravalence section too, can be set as not the user under the situation of continuous water supply amount stage by stage, predetermined output as benchmark, and can set under less than the situation of this output and can shake action or increase waving angle etc.

Because present embodiment has above-mentioned formation, so can obtain following effect.Promptly, water in the water supply container of being located in the refrigerating chamber 2 10 is supplied with in the ice making tray of being located in the refrigerating chamber 4 14 with pump 12, and the vertical of ice making tray 14 is divided into two row with spaced walls 16, and be divided into a plurality of ice boxes with horizontal spaced walls 17, again in spaced walls 16 in length and breadth, 17 are provided with being equipped with in the automatic ice maker refrigerator of guide channel 19, after just in ice making tray 14, supplying water, the CD-ROM drive motor that breaks away from action with the ice that carries out ice making tray 14 imposes and shakes action, so by shaking action flowing to water that water applied, reach the expansion of difference in height, can make the water level homogenising of each ice box 18.Therefore, even existing shipwreck with arrive in ice box portion far away of water supply portion, so owing to needn't make that guide channel is excessive also to can be made into the ice cube that seems very attractive in appearance, and can be made into the also less ice cube of discomfort that connecting portion is produced when being contained in the mouth.And, also needn't make ice making tray 14 is imposed on the output torque of the CD-ROM drive motor of icing the disengaging action greater than required.

In addition, the action of shaking that imposes on ice making tray 14 is shaken in the scope that water is overflowed from ice making tray, and owing to make the width of guide channel 19 that ice making tray 14 is divided into the spaced walls in length and

breadth

16,17 of a plurality of ice boxes 18 become thin width, no matter seem or the equal good ice cube of the mouthfeel when containing ice cube in the mouth so can be made into smaller or equal to 6mm.

And, in the automatic ice maker that the side to two row ice making trays supplies water, be that water supply side uprises and the opposite side step-down because initial shaking moved, so water is overflowed from ice making tray 14.

Have again, because the track of the circle that the rotational trajectory 27 of ice making tray 14 is constituted is approaching with the outer wall 28 of the ice making tray 14 that constitutes ice box 18, so both do not enlarge the setting space of existing automatic ice maker, can use the size of the ice cube that ice making tray 14 makes bigger again than the ice made from existing ice machine.And the shape of ice box 18 is not a semi-spherical shape, and it is compared with semi-spherical shape, more can suppress the raising of ice making tray 14 rigidity, and the ice that is added with under the situation about reversing in ice disengaging action breaks away from and can be easier to.On the other hand, the circle that rotational trajectory constituted of ice making tray 14 and constitute ice box 18 bottom and the outer wall many places between the upper end join or near so that ice box 18 becomes polygonal, so owing to can be made into the ice of corner angle so can be similar to the rectangle ice of selling the market.

And, compare with constituting hemispheric ice box, the torque increase of CD-ROM drive motor can be restricted to minimum, so can have again, can eliminate ice and break away from bad etc. than power saving.

In addition,, make outer wall 28 wall in addition also consistent with the outer wall shape owing to make ice box 18 become polygonal while, thus can be made into the ice of diamond-shaped, thus can be made into the ice of good looking appearance.

And, since constitute ice box 18 bottom and the outer wall between the upper end join so that ice box becomes polygonal while with the round many places that constitute the ice making tray rotational trajectory, it is consistent with outer wall 28 shapes in addition to make outer wall reach the temperature sensor portion of setting in addition, so temperature sensor 30 can be existing installation constitution.

Have again, can change output, and after supplying water, impose the action of shaking of each ice box 18 of making current direction ice making tray 14, so change the operation of the gauge tap of water supply time, the ice that can obtain varying in size by the user to ice making tray 14 to ice making tray 14.On the one hand, shake action and reduce at automatic ice-making pusher side output, and the differences in height in the ice making tray 14 also can flow in the ice box 18 when reducing with water even can impose to ice making tray 14.

And, because the height and position that makes the guide channel of being located on the spaced walls 19 and output are hour the most consistent, can be so can become corresponding to the ice making tray of the change of output.

In addition, owing to for making the variable driving time of supply-water pump 12 that makes of output variable, so it is variable by making to the conduction time of supply-water pump 12, can more easily make to the output of ice making tray 14 also variable, even thereby, also can more easily realize for the selection of the ice of user's multiple size such as large, medium and small.

Have again, owing to shaking action and utilized the CD-ROM drive motor that makes ice making tray 14 rotation, just can impose and shake action to ice making tray 14 so special part or mechanism need not be installed for imposing to ice making tray 14.
