The specific embodiment
Below will describe the present invention in detail.In following paragraph, different aspect of the present invention will be limited in more detail.Each aspect that is limited all can make up with other any various aspects, unless clearly indicate not capable of being combined.Especially, any being specified is favourable or preferable feature can be favourable or the preferable feature combination with being specified of any other.
Embodiments of the invention are now described, Fig. 1 shows ice machine 10, its roughly comprise the ice that can form ice cube form device 12, be used for the storage area (by inlet tube 53 and 14 representatives of ice storage case, the ice storage case is illustrated by the broken lines in the drawings) of stored ice, the transmission district that is used for ice cube is transported to the storage area for example ice tunnel 16 and being configured to detect and move and detect the ice sensing device 18 that ice cube is assembled in ice tunnel 16 along the ice cube of ice tunnel 16.
Ice machine 10 comprises the parts of refrigeration system, so that impel in for example heat exchange between cold-producing medium and the surrounding air of circulation of fluid.Known as prior art, gaseous refrigerant is drawn in the compressor 11, and this compressor makes the temperature and pressure of cold-producing medium raise.Cold-producing medium leaves compressor 11 with gas phase, is condensed into liquid phase by condenser 13 subsequently.More particularly, condenser fan 15 forces flow through heat-exchange tube 17 in condenser 13 of surrounding air.Then, cold-producing medium (unshowned) expansion valve of flowing through, expansion valve makes cold-producing medium expand into the gas and the liquid mixture of low pressure and low temperature.This gas and mixtures of liquids flow into ice subsequently and form (unshowned) evaporator section of device 12 and (as shown in figure 10) ice making chamber is cooled to be preferably the cryogenic temperature that is near or below 5 Fahrenheit temperature (15 degrees centigrade).
Shown in Fig. 2 and 10, utilize the heat-exchange tube 22 of delivery cold-producing medium to cool off ice making chamber 20.More particularly, heat-exchange tube 22 extends near the bottom in ice making chamber 20 in the ice formation device 12, and around the housing coiling that limits ice making chamber 20, and near the top in ice making chamber 20, leave ice formation device 12.The coiling part of heat-exchange tube 22 is surrounded by shell 24 for heat insulation and protection purpose.Shell 24 be preferably by metal for example tin solder make.
Refer again to Fig. 1, the water that ice making is used is transported to the bottom in ice making chamber 20 via supply pipe 28 from hopper 26.The water that ice making is used is preferably by spontaneous current power and is transported to ice making chamber 20.The water that ice making is used is filled into the liquid level identical with hopper 26 usually in ice making chamber 20.
In addition, as shown in the figure 10, feeding screw 30 is positioned at ice making chamber 20 and comprises roughly spiral flight 32.The diameter of flight 32 is slightly less than the diameter in ice making chamber 20, so flight 32 can be removed the ice of the overwhelming majority of assembling on the wall in ice making chamber 20.For example, the flight diameter is preferably than the little 0.001-0.01 inch of ice making chamber diameter, and nearly all ice is removed from ice making chamber wall when rotating with convenient feeding screw 30, except skim.Feeding screw motor 33 makes feeding screw 30 produce the direction rotation of lifter motion along flight by feeding screw drive gear system 35 (Fig. 1).As mentioned above, along feeding screw 30, ice making chamber 20 is roughly filled by water so that the water of close ice making chamber wall is frozen into ice crystal.Therefore, when ice crystal formed, the flight 32 of rotation scraped off ice sheet and along upward to carrying fresh ice from inner surface.
Then, as shown in figure 10, ice is divided into a plurality of ice cubes by the ice cutting head 37 with a plurality of approximate vertical blades 39.The leading edge of each blade 39 is preferably has tapered portion 41 so that be cut into a plurality of ice cubes 38 (Fig. 4 a and 4b) as wedge-shaped part and with ice.Ice cutting head 37 as shown in the figure is connected with feeding screw 30 by pair of bearings 43, so that ice cutting head 37 is with feeding screw 30 rotations.Based on the size and dimension of this ice cutting head 37, ice forms device 12 and can be used for making that ice cube 38 is shaped to required shape and size.
With reference to Fig. 2, ice cube is forced to move up through ice cutting head 37 and the opening 34 through being limited by ice making chamber 20 and ice cutting head 37 subsequently, and the rotary ice device 36 of sweeping is swept away ice cube 38 from opening 34 at this place.Sweep ice device 36 and comprise a pair of protuberance 40 that is connected with main part 42, sweep the ice device and be connected to feeding screw 30, so that corresponding (these two) parts 30,36 rotate synchronously with one another.Main part 42 has the bottom surface of the convergent of arc, and it little by little forces ice cube 38 radially to leave opening 34.When the bottom surface with main part 42 contacts, be broken into a plurality of ice cubes one from the ice that is extruded of ice cutting head 37, form an ice cube 38 thus.Like this, the length of the controlled ice making piece 38 of distance between the bottom surface of the convergent of main part 42 and the opening 34.In addition, when feeding screw 30 with when sweeping 36 rotations of ice device, protuberance 40 further makes ice cube 38 sweep from this opening 34.
In addition, (unshowned) thus ice cube forms device can be positioned on the top of feeding screw 30 so that by forcing ice to compress ice through less basically extrusion orifice.Thereby compacted ice is cut or is broken into less ice cube by the ice parts of cutting in this ice cube forms device subsequently.Except the shape and size that change ice cube 38, above-mentioned aftershaping is handled and will be extruded attached to water on ice, makes every pound of ice of ice cube 38 have higher cooling capacity like this, and has increased the cooling latent heat of ice cube 38.
After discharging from ice making chamber 20, ice cube 38 moves through and transmits the district and enter the ice storage zone.Transmitting the district is limited by the passage between ice making chamber 20 and the ice storage zone.For example, transmitting the district in the accompanying drawings includes but not limited to: near the zone of ice making chamber opening 34, (following will the detailed description in detail) filter screen 50 and ice tunnel 16.
Transmit the district and be the part of usually said food court; This zone is at this equipment and comprises ice in the course of normal operation usually.For example, in the accompanying drawings, the food court includes but not limited to lower member: zone, ice tunnel 16, ice storage tank inlet pipe 53 and the ice storage case 14 of ice making chamber 20, close ice making chamber opening 34.Consume because ice cube 38 is generally used for the crowd, the surface of National SanitationFoundation (national health meeting foundation) rules and regulations possibility contact food should be made by food grade materials.For example, the housing of qualification ice tunnel 16 and ice storage case 14 are preferably by food grade plastic to be made, and the inner surface in feeding screw 30 and ice making chamber 20 is made by grade metal.
The present invention for convenience of description, the part of food court is defined as " clear area ".Clear area 44 comprises that ice forms the exit portion of device and transmits the district.In addition, over cap 46 (Fig. 1) covers ice tunnel 16 and the zone on ice making chamber opening 34, enters into clear area 44 so that prevent dust, dirt and other pollutant, (having saved over cap 46 for convenience of explanation in Fig. 2,4a, 4b).This over cap 46 also is preferably by food grade plastic and is configured to.In addition, over cap 46 is preferably by a plurality of flanges 48 (Fig. 2) and is connected on the housing 45, enters clear area 44 and prevents heat exchange between ice cube 38 and the surrounding air so that prevent pollutant.
As shown in Figure 2, filter screen 50 flows to ice tunnel 16 downwards so that prevent the water of ice-out between opening 34 and ice tunnel 16.Filter screen 50 is preferably permission water is entered water-circulating pipe 52.More particularly, current are through filter screen 50, water-circulating pipe 52, and turn back to supply pipe 28 so that be fed to ice making chamber 20.Perhaps, the different parts of ice machine 10 can be drained or be recycled to water.Filter screen 50 has the gradient that makes progress slightly so that further anti-sealing flows to ice tunnel 16 downwards.
Be formed with ice in ice making chamber 20 after, by the protuberance 40 of rotation, ice cube 38 is forced to sweep away, pass through filter screen 50, move towards ice tunnel 16 by sweeping ice device 36.For example, ice cube 38 is at first directly iced device 36 and is contacted and be forced to move on the filter screen 50 with sweeping.Then, because the degree of being inclined upwardly of filter screen 50, ice cube 38 can not only depend on self gravitation to move in the ice tunnel 16 usually.Yet the ice cube 38 of Xing Chenging is discharged from ice making chamber 20 subsequently, the top that this forces ice cube 38 process filter screens 50 and enters ice tunnel 16.Ice tunnel 16 is downward-sloping basically, so that ice cube 38 can move down in ice tunnel 16 naturally, and is detected by ice sensing device 18.After process ice sensing device 18, ice cube 38 is moved down into ice storage tank inlet pipe 53.
Shown in Fig. 3 was clear, bar 56 comprised that diameter increases collar portion 64, so that form and housing 45 overlapping engaging portion usually, thereby anti-stopping bar 56 moves axially and reduces moisture and moves along bar 56.This bar 56 is preferably and saddle 60 snap-engagement, so that prevent and its disengagement.Yet, form as an alternative, over cap comprises fixed mechanism, for example has the tab of semicircular recess, so that the vertical displacement of anti-stopping bar 56.
At least one end in the end of bar 56 is preferably and extends through housing 45 and stretch out clear area 44.For example, first end 66 extends through first side of housing 45, and the second end 68 extends through a relative side of housing 45.The signal spare of for example blocking sheet 70 is connected on the first end 66 of bar 56, so that contact plate 54, bar 56 and blocking-up sheet 70 rotate synchronously with one another.Shown blocking-up sheet 70 is the thin metallic plate of transversal bar 56 basically.Blocking-up sheet 70 is positioned adjacent to sensor device 72, and it detects the position of blocking-up sheet 70, determines the position of contact plate 54 thus.
As shown in Figure 9, this sensor device is preferably and comprises two hall effect sensors, comprising two magnet 74a, 74b and two sensor element 76a, 76b in the face of second side of blocking-up sheet 70 in the face of first side of blocking-up sheet 70.In the accompanying drawings, magnet 74 is positioned on the inboard of blocking-up sheet 70, and sensor element 76 is positioned at the outside, but also can use opposite layout.In a kind of structure, hall effect sensor has: the supply voltage between the filtered 4.5-5.5VDc (direct current), connect output to ground connection between the dropping resistor and being connected of the Ω of 10K at least output to and ground connection between name be the noise electric capacity of 10nF.When blocking-up sheet 70 when being positioned between magnet 74 and its sensor element 76, the destroyed and sensor element 76 of electromagnetic field sends a signal to controller 78 (Fig. 1).Whether blocking-up sheet 70 has destroyed the electromagnetic field between one group, two groups magnets 74 and sensor 76 or has not destroyed electromagnetic field between arbitrary group, and this can show the position of blocking-up sheet 70 and contact plate 54.
Fig. 2,3,9 shows blocking-up sheet 70 and contact plate 54 and is in neutral position 57, and blocking-up sheet 70 has been blocked electromagnetic field between two groups of magnets and sensor 74a, 74b, 76a, the 76b (make the first and second sensor element 76a, 76b " closure ").Power on acting on blocking-up sheet 70 and contact plate 54 does not exist in the time of maybe can ignoring, and blocking-up sheet 70 and contact plate 54 are in neutral position 57.Specifically, when not having ice cube 38 when ice tunnel 16 moves, blocking-up sheet 70 and contact plate 54 are in neutral position 57 usually.
Fig. 4 a shows at normal ice making operating process medium floe 38 and moves along ice tunnel 16.Specifically, the ice cube 38 of lesser amt 20 is discharged and is moved towards inlet tube 53 and ice storage case 14 from the ice making chamber, activates this contact plate 54 thus forward and enters primary importance 80.When contact plate 54 and blocking-up sheet 70 were in primary importance 80, blocking-up sheet 70 only was positioned between the first magnet 74a and the first sensor element 76a, disconnected first sensor element 76a thus and showed the position of contact plate 54 to controller 78.In this position, limit first angle 82 between blocking-up sheet 70 and the vertical direction.In other words, when contact plate 54 contacted with the ice cube 38 of situation of movement 79, blocking-up sheet 70 is the 57 previous amounts that equal first angle 82 that pivot from the neutral position.After ice cube 38 moved through ice sensing device 18, contact plate 54, further described as following to neutral position 57 by the gravity backswing.In addition, combine so that will block sheet 70 with above-mentioned gravity from the magnetive attraction of magnet 74a, 74b and push the neutral position to.
Fig. 4 b shows the situation 83 that ice cube 38 is assembled along ice tunnel 16 when the ice storage zone is full of.Specifically, the ice cube 38 of a greater number is prevented from entering in the ice storage zone, and they be in one above the other contact plate 54 below, further before thus activate contact plate 54 and enter the second place 84.When contact plate 54 is in the second place 84 with blocking-up sheet 70, blocking-up sheet 70 is not positioned between the magnet 74 and sensor element 76 of sensor device 72, the off-state that keeps first sensor element 76a thus, and disconnect the second sensor element 76b, and show the position of contact plate 54 to controller 78.In this position, limit second angle 86 between blocking-up sheet 70 and the vertical direction greater than first angle 82.
After the gathering situation 83 of having eliminated ice cube 38, contact plate 54 arrives neutral position 57 by gravity and magnetive attraction backswing.Yet some ice cubes 38 take out from the ice storage zone in the delivery process up to some or all of ice cube thawings or up to for example icing, and gathering situation 83 can not be eliminated usually.Latter event in the both of these case is preferred, and because the lower temperature in housing 45 thereby more may occur.
The second end 68 of bar 56 comprises counterweight portion 88 so that the weight of balance blocking-up sheet 70.Specifically, sensor element and counterweight portion 88 have weight about equally, so that the end 66,68 of anti-stopping bar 56 is pushed out from saddle 60.In addition, counterweight portion 88 can be configured to react on the weight of blocking-up sheet 70 in rotation, so that shift contact plate 54 onto neutral position 57 (Fig. 2).For example, cantilevered counterweight portion 88 produces the moment of torsion that acts on bar 56, contact plate 54 and blocking-up sheet 70, shifts contact plate 54 onto neutral position 57 so that impel.Specifically, shown in Fig. 4 a, when contact plate was in primary importance 80, counterweight portion was in its primary importance 92 and impels and shift contact plate 54 onto neutral position 57.Similarly, shown in Fig. 4 b, when contact plate 54 was in the second place 84, counterweight portion was in its second place 94 and also impels and shift contact plate 54 onto neutral position 57.
Although dispensable, preferably on housing 45, form a groove 96.Groove coupling on the opposite side in this and the sensor device 72, that be positioned at housing 45, blocking-up sheet swing process is so that simplify the processing of manufacturing equipment.By this way, identical part can be molded in both sides, although magnet and sensor only are installed on sensor element 72 1 sides.
Perhaps, ice sensing device 18 can be an electronic installation, for example optical sensor, infrared ray sensor or other any suitable device.As another kind of alternative structure, alternative sensor element can be connected with above-mentioned mechanically actuated ice sensing device 18, and for example optical sensor components is determined the position of mechanically actuated plate.In another alternative structure, ice sensing device 18 comprises that only for example single magnet 74 of pair of sensors parts and single-sensor element 76 are to detect the position of blocking-up sheet 70.In such structure, ice sensing device 18 be can not determine the rotation degree of blocking-up sheet 70, but it can determine to block the time period that sheet 70 keeps rotation status.The time period of plate displacement is useful especially, and this is because common time period weak point than the plate displacement that is caused by the gathering situation 83 of ice cube 38 of the time period of the plate displacement that occurs being caused by the situation of movement 79 of ice cube 38.Therefore, controller 78 determines to have taken place any situation (normal ice mobile 79 or ice assemble 83) based on the time period of plate displacement usually.
If hopper 26 comprises first mechanism of the water surface that is used for controlling hopper 26 and this water surface and is lower than predetermined threshold then makes ice form second mechanism that device 12 is shut down.For example, shown in Fig. 6-8, hopper 26 comprises float-controlled valve 100 that is configured to control the current volume flow that enters in the hopper 26 and the water level sensor 102 that is configured to detect the water surface in hopper 26.
Float-controlled valve 100 is mechanically actuated float-controlled valves, the linking arm 108 that it has float part 104, valve 106 and extends betwixt.Predetermined height in float part 104 is positioned at hopper 26 or thereon time the, linking arm 108 make valve 106 (float part 104 that dotted line is as shown in Figure 7 represented) in the closed position.When if float part moves under the predetermined altitude, linking arm 108 makes valve 106 move to open position, makes water flow into hopper 26 thus.
If the water surface in hopper 26 is in undesirable low water level, if perhaps hopper 26 is empty, the water that ice making chamber 20 can not receive q.s comes ice making.In addition, lacking water in ice making chamber 20 may cause the ice making cavity temperature to drop to undesirable degree; Cause forming the damage of device 12 thus for ice.For example, if there is not water to exist in ice making chamber 20, temperature therein may be low excessively, and the wall in ice making chamber 20 may for good and all be out of shape; To stop so effectively to scrape between the wall in feeding screw 30 and ice making chamber 20 to contact, and may damage feeding screw 30.
In addition, hopper 26 comprises the drainpipe 118 that is used for from hopper 26 discharge waters when needing.For example, when carrying out for the maintenance of ice machine 10 and cleaning, desirable is discharge water from this system.In the normal running of ice machine 10, (unshowned) unloads that water solenoid valve is closed drainpipe 118 so that keep the required water surface in hopper 26.
With reference to Fig. 5 a, below with the method 120 of description control ice machine.Operate in 122 processes in initial start, ice machine 10 is started working, and the start-up operation timer that is arranged in controller 78 in step 124 is reset and restarted.Then, in step 126, whether controller 78 inputs have moved forward to primary importance 80 from the signal of first sensor element 76a so that determine blocking-up sheet 70.In other words, controller determines whether ice cube 38 forms device 12 by ice and make.If ice formation in the section start-up time at 8 minutes in step 127, then the safe shutdown pattern of step 128 is shut down and switched to ice machine 10, as described in detail below.In the start-up time section, if mistake when ice forms, occurs, under this fault state in first operation of 8 minutes ice form device 12 and also not have generation usually for feeding screw 30 or the serious damage of feeding screw motor.Specifically, when starting, the temperature that forms in the device 12 at ice is enough warm usually, makes that the water in ice making chamber 20 can not be frozen into solid-state ice cube in first 8 minutes after starting.Therefore, clean boot time period normally time period of 8 minutes.Yet, in another structure, can change this of section start-up time.
Yet, if in start-up course, in ice making chamber 20, do not have water, to such an extent as to the wall that the enough length of 8 minutes section start-up time can freezing ice making chamber 20; Make wall be out of shape like this.Therefore, if hopper has undesirable low liquid level, controller 78 is preferably and makes ice machine 10 shut down.For example, as mentioned above, in case controller 78 sends the signal that the water surface is lower than predetermined extent, controller 78 will be waited for 20 seconds before switching to the safe shutdown pattern.Yet if the water surface rose in the process at 20 seconds or surpass predetermined level, controller 78 will restart normal operation.
In case first sensor element 76a shows ice making, in step 129 ice machine 10 enter normal mode operation and in step 130 the normal running timer reset and restart.In normal mode operation 129, controller 78 imports continuously from the signal of first sensor element 76a whether moved forward to primary importance 80 so that determine blocking-up sheet 70 in step 132.If not ice formation in the section at the fixed time, then the safe shutdown pattern of step 128 is shut down and switched to ice machine 10, below will describe in detail.Term " predetermined amount of time " refers at the fixed time, and section begins a definite time period in any moment before.For example, predetermined amount of time can be the stipulated time section that is programmed in the controller.As another example, predetermined amount of time can be the variable time section that is calculated by controller.
Predetermined amount of time is based on variable field of activity (activity window) time period that nearest ice activity is calculated by controller in the embodiment shown in Fig. 5 a.If do not detect ice in the variable field of activity time period in step 131, then the safe shutdown pattern of step 128 is shut down and switched to ice machine 10.For example, the variable field of activity time period is the time period that scope changed based on nearest ice making activity from minimum 90 seconds to maximum 135 seconds.Specifically, if the quantity that has detected formerly with the long time interval is the ice cube of X, for example the time between contact plate 54 corresponding displacements is 80 seconds, field of activity then corresponding higher (wherein variable " X " is the setting numerical value that is programmed in the controller).Yet if the quantity that detects formerly with the short time interval is the ice cube of X, for example the time between contact plate 54 corresponding displacements is 20 seconds, and field of activity is corresponding to equal 90 seconds.
If form ice in the normal working time section, whether controller then is displaced to the second place 84 from the second sensor element 76b input signal so that determine blocking-up sheet 70 step 134.In other words, controller input signal is so that determined whether to occur the gathering of ice cube 38.If the ice cube gathering, then the ice machine 10 ice storage case of shutting down and switch to step 129 is full of pattern, below will describe in detail.Do not assemble if ice cube occurs, then the normal running timer is reset and is restarted.Therefore, in the course of normal operation of ice machine 10, it is in running order that ice forms device 12, does not have ice cube 38 can make contact plate 54 displacements or up to the gathering 83 that ice cube 38 occurred in the time period that is equaling field of activity.
Although the flow chart in Fig. 5 a shows the step 134 of only carrying out after step 132; but in alternate embodiment; in case the electromagnetic field relevant with the second sensor element 76b is disconnected; the controller system that makes immediately switches to safe shutdown step 129, with irrelevant with respect to the timing interrupt of ice making operation.
Followingly safe shutdown pattern 128 is described with reference to Fig. 5 b.Usually, when system broke down, controller 78 made ice machine 10 shut down.Controller 78 repeatedly attempts to restart ice machine 10 subsequently, till the main time period then.This main time period makes controller 78 can carry out restarting of limited quantity so that this system can overcome the problem that can solve naturally, for example low evaporimeter start-up temperature, do not need repairing or the problem of other intervention but do not allow for good and all to attempt to overcome, for example fault or do not wish that the water supply that occurs is little.
After the system failure occurring, ice machine was waited for a secondary time period before attempting to restart ice machine 10.This pair time period will provide ice machine to overcome the above-mentioned required any time of the problem that can solve naturally.
Shown in Fig. 5 b, determine to restart indicator signal at step 136 middle controller 78 and whether equal " being (yes) ".Equal "Yes" if restart indicator signal, 10 of ice machines have carried out restarting recently and master timer continues timing, rather than reset in step 137 and restart.In other words, equal "Yes" if restart indicator, master timer then continues timing, and does not reset.Yet, equaling " not (no) " if restart indicator, ice machine 10 does not also live through fault and master timer recently and should reset and restart.
Then, in step 138, no matter whether ice machine 10 restarts recently, and secondary timer is reset and restarted.As mentioned above, secondary timer calculated a suitable stand-by period before attempting to restart.Specifically, in step 140, determine a secondary time period randomly.For example, a predetermined basic stand-by period (for example 8 minutes) joins in the random time section (for example any integer value between 0-52 minute), so that determine the secondary time period.In case the secondary time period is calculated, in step 142, whether then controller will continue to determine the secondary time period.
The secondary time period at random may be favourable, so as by setting less " downtime " that causes by system mistake thus improve the efficient of ice machine 10.Many system failures may be corrected by system-down.For example, if the ice in ice making chamber 20 is blocked up and the rotation of prevention feeding screw 30, ices and to melt in the section in specific downtime.Yet, for controller, can not dope duration of required this of section usually downtime; Cause too short and situation that ice does not melt fully of section downtime and the long and ice machine of section downtime unnecessarily to be set in the situation of holding state like this.Therefore, the secondary time period at random produces a series of variable downtime of section based on a series of shutdown, may obtain desirable section downtime.
In case the secondary time period then, in step 144, controller determines whether master timer has moved the thresholding time, for example 300 minutes.As mentioned above, if master timer has moved this thresholding time, ice machine 10 will be in step 146 dead halt and stop restarting automatically, manually restart by the technical staff up to this system.Yet if master timer does not also move this thresholding time, this system will restart indicator and be set at "Yes" and restart this system in step 150 in step 148, turn back to the step 122 shown in Fig. 5 a thus.When master timer then and ice machine 10 when entering shutdown mode 146, in step 145, restart indicator and automatically be set at " not (NO) ", so that ice machine 10 does not write down the nearest situation that restarts after this system manually restarts.
This ice machine 10 also can be worked under different control models.Usually, in decision design, these patterns are: start-up mode, normal ice-make mode, cleaning mode, safe shutdown pattern, ice storage case are full of pattern and shutdown mode.
Substantially, start-up mode is the pattern of power supply when applying or applying again, is commonly referred to as P.O.R.If bypass cock is not pressed, then before entering next state, force one 5 minutes delay in this state.The purpose of 5 minutes delay is to protect feeding screw drive gear system 35 and compressor 11.For example, if the water in ice making chamber 20 be frozen into feeding screw drive gear system 35 can vitiable temperature, this time period can be used for making ice-out.In addition, if ice machine 10 is moving when power interruptions, evaporimeter and the cold-producing medium that is stored in wherein are still colder when power supply applies again.If allow colder cold-producing medium to enter into compressor 11, compressor 11 may damage.Therefore, 5 minutes time delay makes evaporimeter warm naturally and makes liquid refrigerant change gaseous state into before entering compressor 11.
In the start-up mode process of ice machine,, enter start-up mode if toggle switch is in " Ice (ice) (" opening ") " position and sensor element 76a, 76b all are in closure.Toggle switch is that manually operated switch is so that the end user is switched ice machine 10 between different mode (ice-make mode, cleaning mode, shutdown mode).This control is examined and is right after talent for swimming slowdown monitoring switch connection after this gear motor 35 starts.After 5 minutes postponed, compressor and fan motor started.
If this system is in the state of restarting, wherein, the second sensor element 76b causes system-down owing to disconnecting, before starting, must pass through 5 minutes time period.After 5 minutes time period, have situation below suitable then starter receiver motor immediately if control: first sensor element 76a closure, connect less than 30 minutes and talent for swimming slowdown monitoring switch downtime.After 5 seconds postponed, compressor and fan motor started.Unloaded the water solenoid valve energising 30 seconds and outage subsequently, so that open and close drainpipe 118 so that wash hopper 26 and fresh ice making water is provided.After the talent for swimming slowdown monitoring switch was connected once more, compressor and fan motor started.
For ice cube ice machine and borneol ice machine, (if system is owing to power interruptions is shut down) in the power breakdown restart procedure, when power up, this system carried out 5 minutes time delays before beginning to start sequential.After this time delay, for example the signal of one group of LED (light emitting diode) will glimmer.If push bypass cock then walk around this time delay.Control panel can have 7 light emitting diodes (LED), and they have following function:
LED #1: ice cube (NUGGET)-redness, when lighting, it represents that control device is configured for the ice cube ice machine
LED #2: borneol (FLAKE)-redness, when lighting, it represents that control device is configured for the borneol ice machine
LED #3:HES#1-green, it is worked together with hall-effect switch # 1
LED #4:HES#2-green, it is worked together with hall-effect switch # 2
LED #5: cleaning (CLEAN)-yellow, when lighting, it represents that system is in the cleaning course
LED #6: safeguard (MAINT)-redness, when it is lighted, need to represent maintenance work.This LED only is used for control device and is configured for the ice cube ice machine when using
LED #7: normal (WATER the OK)-green of water, it (has enough water) together with the work of talent for swimming slowdown monitoring switch when this switch connection, and this light emitting diode is lighted, and light emitting diode turn-offs when this switch disconnects.
In normal operation mode, as mentioned above, the ice of discharging from evaporimeter contacts and falls into the ice storage case with contact plate 54 discontinuously.Control device learns that first sensor element 76a disconnects discontinuously and be closed again: this is used for determining that this system normally works.In first 8 minutes of operation, control device must learn that first sensor element 76a at least once disconnects and closure.After first 8 minutes of operation, control device must learn the disconnection of at least one the first sensor element 76a and closed again in field of activity.If control device does not learn the disconnection of this first sensor element 76a and closed again, this system forwards the safe shutdown pattern as described below to.If this water sensor switch of any moment in course of normal operation keeps disconnecting continuous 20 seconds, this system forwards the safe shutdown pattern as described below to, and " water normal (WATER OK) " LED flash.
In any moment that is in operation, if the second sensor element 76b disconnects, this system enters the ice storage case and is full of pattern.In this shutdown mode, compressor/fan motor and gear motor cut off the power supply immediately.In case this system-down must keep shutting down 5 minutes before allowing aforesaid restarting.In stopping process, with the relevant LED flash of HES#2 (hall-effect switch), show that the ice storage case is full of pattern, if the second sensor element 76b is in running order.
For when definite this system should clean, the time before timer monitoring and tracking cleaning or the flushing work (hour).When energising, this timer is set at zero.After moving each hour, this timer increases progressively.In addition, in the process of " random stop " described in the safe shutdown pattern, this timer does not increase progressively.Cleaning course also can automatically begin.When cleaning timer arrived 50 hours, this system stopped ice making and carries out cleaning course as described below, and turns back to ice making.This cleaning timer is reset to zero.If clean cycle is manually actuated by toggle switch, this cleaning timer also is reset to zero.
In cleaning course, the light emitting diode of the yellow on control panel " cleaning (CLEAN) " is lighted.The water sensor switch breaks and closure at cleaning course; This is normal, and should ignore by controlled device.Time period and operation of components in cleaning course provide in table 1.
