Control device 17, based on these input signals, according to the ice making operation control program described later of the pre-stored built-in memory (not shown) at this control device 17, control supply-water pump motor 24, ice-making disc motor 40, drawdown pump 32, water intaking valve 30, feed water valve 35, pressure-reducing valve 33.
Below, with reference to the flow chart shown in Fig. 5, the ice making action of present embodiment is described.
After switching on power, control part 17 is first as initial actuating, and standby is until through 90 minutes (step S1), standby until the detected temperatures of ice-making disc temperature sensor 41 lower than-12 ℃ (step S2).
Cooling along with in ice-making compartment 4, ice-making disc temperature is during lower than-12 ℃, control device 17, as detecting ice action, by ice storage amount test rod 42, carried out the detection action (step S3) of the ice storage amount in ice container 39, signal based on carrying out self-satisfied ice sense switch 43, judges whether ice storage amount reaches brimmer state (step S4).
Now, if ice storage amount is brimmer state, standby until user take out after ice when ice storage amount reduces.
Then, control device 17, by ice-making disc motor reverting system ice pan 36 Shang Xia 40, carries out separate ice action (step S5) by twisting.In this situation, owing to also not supplied water in ice-making disc 36, therefore should be not in ice making, in the situation of the former thereby power up owing to having a power failure etc., even if there is water in ice-making disc 36, due to this separate ice action, in ice-making disc 36, become empty state.
After such separate ice action, control device 17, by ice-making disc motor 40 reverting system ice pans 36, confirms that by horizon sensor 44 level of ice-making disc 40 maintains, and returns it to original level.
Then, control device 17, by the signal from ice-making compartment door switch 11, judgement ice-making compartment door 4a closes (step S6), and water intaking valve 30 and feed water valve 35 are opened to (step S7).
At this, control device 17 carries out the water supply time started to ice-making disc 36 of built-in timer to be set, and starts the timing of timer.In addition, when first water supply, owing to not holding and staying water in storage part 29, so not 29 water supply to ice-making disc 36 from storage part.From for the second time, the water in storage part 29 is supplied to ice-making disc 36 from feed pipe 34 via feed water valve 35.
Then, control device 17, cuts out feed water valve 35 (step S8), and open pressure-reducing valve 33 (step S9) makes 24 actions of supply-water pump motor, carries out from supply tank 18 water supply (step S10) of 29 to storage part.
In addition, till this constantly, supply tank 18 with supply the state of the water used of ice making be arranged in refrigerating chamber 3.
By supply-water pump 21, from supply tank 18, draw the water of ormal weight (for example, as the required water yield of ice making, a 100ml), via discharge pipe 26, water receiving case 27, feed pipe portion 28, water intaking valve 30, stockpile in storage part 29.
Afterwards, control device 17, cuts out water intaking valve 30 (step S11), and making in storage part 29 is air-tight state, drives drawdown pump 32 (step S12).Now, 29Nei space in storage part is depressurized via pressure-reducing valve 33.
The action of drawdown pump 32 starts by (step S13) after clock afterawhile, and control device 17 cuts out pressure-reducing valve 33, stops drawdown pump 32 (step S14), and decompression was carried out after one minute, was set as roughly reducing pressure 0.6atm in storage part 29.
Pressure-reducing valve 33 becomes check-valves, becomes by water intaking valve 30 and feed water valve 35 (closure mechanism) and therefore airtight state, maintains decompression state in storage part 29, thus, carries out the degassed of water in storage part 29.
Fig. 6 will enter the figure to the variation of the dissolved oxygen content of the water in the container of following time process in the situation of authorized pressure (0.65atm, 0.5atm, 0.3atm) of decompression in the 150ml container of 100ml water, as shown in Figure 6, post-decompression state continuance the dissolved oxygen content of the water in storage part 29 reduce.
That is,, by decompression, the air being added in the water in storage part 29 is run out of, and carries out degassed.
After drawdown pump 32 stops, control device 17 turns back to step S1 again, still, at this, constantly for having, is not carrying out to the state of ice-making disc 36 water supply, so same as described above, execution step S1~S6, enters step S7.
Afterwards, control device 17, open water intaking valve 30 and feed water valve 35, be supplied to ice-making disc 36 (step S7) by carried out degassed water in storage part 29.Below, control device 17 is carried out above-mentioned step S8~S14, and to storage part, 29 supply water, and carry out degassed.
Then, after supplying water to ice-making disc 36 through 90 minutes during (step S1), the water after degassed in ice-making disc 36, owing to freezing, generates transparent ice gradually.
Afterwards, along with cooling in ice-making compartment 4 and the detected temperatures of ice-making disc temperature sensor 41 during lower than-12 ℃ (step S2), control device 17 detects ice action (step S3), by full ice sense switch 43, judge that whether ice storage amount becomes brimmer state (step S4), carries out separate ice action (step S5) by ice-making disc motor 40.
Thus, in ice container 39, stockpile transparent ice.Below, control device 17 repeats ice making action same as described above.
In addition, control device 17, while supplying water to ice-making disc 36 (step S7), the detected temperatures based on ice-making disc temperature sensor 41, has judged whether water supply.Due to refrigerating chamber 3 in the supply tank 18 of temperature in uniform temp in the entering ice-making disc 36 of water and ice-making disc 36 temperature raise, therefore, the in the situation that of becoming more than-9 ℃ in detected temperatures, water is just at the supply system ice pan 36, and control device 17 carries out common action.
In addition, in the situation that this detected temperatures does not reach more than-9 ℃, from storage part, 29 not supply feedwater to ice-making disc 36, or are supplied to the considerably less of ice-making disc 36, and in this situation, control device 17, by lighting water supply lamp etc., has informed the water sky of supply tank 18.
By present embodiment, in the way by the water supply path between supply tank 18 and ice-making disc 36, storage part 29 is set, by 29Nei space, 32 pairs of these storage parts of drawdown pump, reduce pressure, thus, carry out the degassed of water in storage part 29.
By water intaking valve 30 being set in the way in feed pipe portion 28 and the so simple formation of feed water valve 35 being set in the way of water inlet pipe 34, storage part 29 can form air-tight state.
Thus, by becoming complicated, maximize without being used in the degassed closed structure of decompression, therefore can form and low cost generates the high water of transparency by simple.
In addition, can in ice making, carry out the degassed of water that next ice making uses, the water of having supplied with degassed continuously, can generate transparent ice efficiently.
In addition, owing to maintaining air-tight state by water intaking valve 30 and feed water valve 35, therefore, do not need to make continuously drawdown pump 32 work, can suppress power consumption.
In addition, the water yield controlling organization forming by supply-water pump 21, water intaking valve 30 and feed water valve 35, the water yield of the regulation fewer than the capacity of supply tank 18 will be set as, as the required water yield of ice making, be supplied to storage part 29, can only to a small amount of water, carry out degassed, therefore degassed efficiency is high, has suppressed power consumption.

That is, bypass pipe portion 142 within it portion be formed with bypass path 145.It is larger than the internal diameter (inner side area) of the feed pipe portion 125 that forms water supply path 126 that this bypass pipe portion 142 is set as its internal diameter (inner side area).
In addition, bypass pipe portion 142 is set to oliquely downward extend and oliquely downward extend towards interflow portion 144 from branching portion 143.
Below, the electric formation of refrigerator 101 is described.
Figure 16 represented the 4th embodiment refrigerator 101 particularly about the electric formation of automatic ice-making.
Refrigerator 101 has control part 150, and this control part 150 consists of the microcomputer with not shown CPU, RAM, ROM and I/O bus and the timer of instrumentation time 151 etc.
Control part 150 is stored in such as the control program on ROM etc. by execution, controls 101 integral body of refrigerator.Specifically, control part 150 passes through drive compression machine 112 etc., and each storeroom is controlled to design temperature.
Signal from ice-making disc temperature sensor 130 and full ice sense switch 132 is input to this control part 150, control part 150 is based on these signals, according to above-mentioned control program, control supply-water pump motor 120, ice-making disc motor 129, water intaking valve 135, feed water valve 138, drawdown pump 139 in addition.
Below, automatic ice-making is processed and is elaborated.
The control part 150 of refrigerator 101, after power connection, carries out not shown main processing, mainly carries out the control of freeze cycle.In addition, control part 150 and present embodiment explicitly, are carried out the automatic ice-making shown in Figure 17 and are processed.
This automatic ice-making is processed, by such as execution such as interrupt routines.In addition, in the following description, supply tank 113 with supply the state of the water used of ice making be arranged in refrigerating chamber 103.
Control part 150, starts, after ice making processing, after the water supply of judging last time, whether to have passed through 90 minutes (step S101) by timer 151, and in the situation that not passed through 90 minutes, (NO of step S101), turns back to step S101.
That is, from last time supplying water till through standby in 90 minutes.Be judged to be from last time supplying water through 90 minutes time (YES of step S101), whether judge by the detected ice-making disc temperature of ice-making disc temperature sensor 130 lower than-12 ℃ (step S102), in ice-making disc temperature, be (NO of step S102) more than-12 ℃ in the situation that, turn back to step S101.
That is, in ice-making disc temperature, be more than-12 ℃ in the situation that, be in the state that has water in ice-making disc 114, also do not generate the state of ice, therefore, standby until ice-making disc temperature lower than-12 ℃.
In addition, in ice-making disc temperature, lower than-12 ℃ in the situation that (YES of step S102), control part 150 judges whether ice storage amount is brimmer (step S103).
That is, the signal of the full ice sense switch 132 based on from opening by ice storage amount test rod 131, judges whether ice container 128 is brimmer.In the situation that ice container 128 is brimmer (NO of step S103), the judgement of repeating step S103.
That is, standby until for example user take out ice and ice storage amount reduces, when being judged as ice storage amount and reducing (NO of step S103), carry out separate ice action (step S104).
Particularly, by ice-making disc motor 129, ice-making disc 114 is rotated to and spun upside down, and carry out the ice in separated ice-making disc 114 by ice-making disc 114 further being applied to twisting.
Then, control part 150, open feed water valve 138 and water intaking valve 135 (step S5).Thus, the water in storage part 137, that is, the water stockpiling as described later while carrying out ice making last time action after storage part 137 degassed is supplied to ice-making disc 14.
In addition, in step S101, S102 and S103, not needing control part 150 necessarily to make CPU is simple holding state.
; in step S101 through the moment output signal after 90 minutes; in step S102; in the moment output signal becoming below-12 ℃; in step S103, at full ice sense switch 132, become the moment output signal of closing; these signals can be processed and accepted by interruption, carry out later processing.
Then, control part 150 sealing feed water valves 138 (step S106), thus, from the supply tank 113 shown in Figure 18, to the water supply path 126 storage part 137, become open state, and to the water supply path 126 ice-making disc 114, become closed state from storage part 137.
Then, the driving of water supply start pump motor 120 (step S107).Thus, the supply-water pump 117 in supply tank 113 drives, and the water in supply tank 113 is discharged to water supply path 126.
In this situation, control part 150, during till the water of discharging the required ormal weight of an ice making, drives supply-water pump motor 120.
The internal diameter of the valve member of water intaking valve 135 is several millimeter as described above.Therefore, the water intaking valve 135 that is flowing in of the water of supplying with from supply tank 113 is hindered, and before flowing into storage part 137, above water intaking valve 135, is temporarily detained, and therefore, the upstream side of the water intaking valve 135 on water supply path 126 arranges interim storage part 134.
This interim storage part 134, as mentioned above, has the water yield large volume more required than an ice making, and therefore, the water yield that the volume settings of the water supply path 126 of the upstream side of water intaking valve 135 must be more required than an ice making is large.
Thus, in the situation that to storage part, 137 confessions are fed water, water can not overflow from the top of water receiving case 124.
In addition, control part 150, while driving supply-water pump motor 120 in step S107, drawdown pump 139 also drives simultaneously.Because pressure-reducing valve 141 is check-valves, therefore drive after drawdown pump 139, suck the air in storage part 137 and be discarded in refrigerator.
Thus, only by the upstream side at water intaking valve 135, hold under the state that leaves water and drive force (forcing) pump 139 with the stipulated time, can promote to storage part the inflow of 137 water.
In the situation that storage part 137 stockpiles the required water of once ice making, control part 150 stops supply-water pump motor 120 (step S108), the driving of drawdown pump 139 also stops for the time being, the upstream of water intaking valve 135 is held the water staying and is all flowed in storage part 137, sealing water intaking valve 135 (step S109).
Thus, degasser 136 becomes following state, that is, the upstream side of the storage part 137 of water supply path 126 seals by water intaking valve 135, and the downstream of storage part 137 is sealed by feed water valve 138 as described above.
In addition between storage part 137 and drawdown pump 139, by pressure-reducing valve 141 sealings as check-valves.That is, the storage part 137 of degasser 136 becomes state airtight and that watertight ground is airtight.
Under this state, control part 150 drives drawdown pump 139 (step S110).Drive the air in the rear storage part 137 of drawdown pump 139 to be discharged in refrigerator via drawdown pump 139 from pressure-reducing valve 141.
Thus, storage part 137Nei space A (with reference to Figure 15) is depressurized.Then, judge from force (forcing) pump 139 and drive and start whether to have passed through one minute (step S111).That is, in the present embodiment, control part 150, continues one minute by the decompression action of storage part 137.
In addition, the time of the one minute example that is present embodiment.Control part 150 is judged to be through one minute time (YES of step S111), stops drawdown pump 139 (step S112).Afterwards, control part 150 enters step S101.
In step S101, control part 150 standby is as described above until through 90 minutes.That is, in storage part 137, maintained the decompression state of 90 minutes.After space A decompression, be dissolved in the air in water W (with reference to Figure 15), and form poised state between the A of space, be therefore released in the A of space.Like this, the dissolved air amount of water W reduces, and, carries out the degassed of the water W that undertaken by the decompression of space A that is.
Control part 150, through after 90 minutes (YES of step S101), is carried out the later processing of above-mentioned steps S102.Thus, the water after degassed is supplied to ice-making disc 114, becomes ice after cooling.
In this situation, by water degasification, generate the few transparent ice of air entrapment.The control part 150 of refrigerator 101 is carried out in this wise automatic ice-making and is processed.
In above-mentioned automatic ice-making is processed, water intaking valve 135, feed water valve 138 or supply-water pump 117 etc. have the danger of breaking down such as the use due to long-term etc.For example, water intaking valve 135 faults, water supply path 126 becomes the state of sealing always, and the water of supplying with from supply tank 113 can not flow into storage part 137.
In this situation, by interim storage part 134 is set, can hold the water that stays amount once.But water intaking valve 135 grades continue to fault automatic ice-making to be processed, and has the danger that the water of supplying with for the second time can be filled interim storage part 134 always later.
Similarly, at supply-water pump 117, breaking down and continue to supply water action in the situation that, is also to have at the flow water that hindered of water intaking valve 135 to fill the danger of interim storage part 134.That is,, in the situation that water intaking valve 135, feed water valve 138 etc. breaks down, the water that ice making is used overflows and is trapped in refrigerator from water supply path 126.
Therefore, on the refrigerator 101 of present embodiment, be provided with bypass pipe portion 142.As mentioned above, near the branching portion 143 of bypass pipe portion 142 upper end of interim storage part 134 is connected with interim storage part 134.
In this situation, branching portion 143 is arranged on the required many positions of the water yield of an ice making of volumetric ratio of the water supply path 126 between branching portion 143 and water intaking valve 135.In other words, stockpiling under the state of the required water yield of water yield ice making over a time in interim storage part 134 this water inflow bypass pipe portion 142.
This bypass path 145 is walked around after degasser 136, again with water supply path 126 interflow.That is, the water of inflow bypass path 145 is finally supplied to ice-making disc 114.Thus, even if for example water intaking valve 135 breaks down, water supply path 126 becomes the state of sealing always, also can from water supply path 126, overflow by anti-sealing.
Similarly, even break down at feed water valve 138, in the situation that storage part 137 and interim storage part 134 are filled by water, also can from water supply path 126, overflow by anti-sealing.
As mentioned above, in the refrigerator 101 of this 4th embodiment, can obtain following effect.
The bypass pipe portion 142 of degasser 136 is walked around in setting, therefore for example at water intaking valve 135, feed water valve 138, break down and water fill water supply path 126 in the situation that, or, supply-water pump 117 breaks down and continues in the situation of discharge of water, and the current of discharging from supply tank 113 are supplied to ice-making disc 114 through bypass 145.
So, can prevent water that ice making uses from feed path, overflow and be trapped in refrigerator, such as reception room 133 is interior etc., user cleans difficult place.
Owing to being provided with interim storage part 134, even hindered by the mobile of water of water intaking valve 135, water can not overflow from water supply path 126 yet.So, can prevent that hydropexis is in the refrigerators 101 such as reception room 133, refrigerating chamber 103, refrigerating chamber 104.
The internal diameter of bypass pipe portion 142 (inner side area) is set greatlyr than the internal diameter of feed pipe portion 125.The internal diameter of feed pipe portion 125 is set as the smooth mobile size of water of supplying with from service tank 113 originally.
Therefore,, by the internal diameter of bypass pipe portion 142 is set greatlyr than the internal diameter of feed pipe portion 125, water flows smoothly in the bypass path 145 forming by bypass pipe portion 142.
Therefore, for example, continue the supply of water in the situation that supply-water pump 117 breaks down, water not only flows into water supply path 126 and also flows into bypass pipe portion 145.So, can from water supply path 126, overflow by anti-sealing.
When driving supply-water pump motor 120, drawdown pump 139 is also driven together.Thus, promoted that by water intaking valve 135, having been hindered mobile water flow into storage part 137.In addition, can shorten water and stockpile the time till storage part 137, shorten further the ice making time.
In the present embodiment, storage part 137 being formed to lower end side with interim storage part 134 is the taper that front end is thin.Thus, can prevent hydropexis in storage part 137 or in interim storage part 134.
In addition, bypass pipe portion 142 is formed from branching portion 143 and oliquely downward extend and oliquely downward extend towards interflow portion 144.Thus, can promote flowing of water from from feed path 126 to bypass path 145.
(the 5th embodiment)
Based on Figure 19, the water supply path of the refrigerator of the 5th embodiment, degasser, bypass path are described.In the 5th embodiment, water intaking valve consists of triple valve, and water intaking valve formation bypass path, and these are different from the 4th embodiment.In addition, the main composition of the 5th embodiment is identical with the 4th embodiment.
In the water supply path 126 and bypass path 145 of the 5th embodiment, as shown in figure 19, water intaking valve 160 consists of triple valve.One end of this triple valve is connected with bypass pipe portion 142 via auxiliary bypass pipe portion 161.
Water intaking valve 160, is switched to the water of supplying with from supply tank 113 any of degasser 136 sides or bypass pipe portion 142 sides.That is, also to form the branch point of water supply path 126 and bypass path 145 be branching portion 162. to the water intaking valve 160 of present embodiment
The control part 150 of refrigerator 101 is by this water intaking valve 160 is switched to water supply path 126 sides, with above-mentioned the 4th embodiment similarly, water can be stockpiled in storage part to 137 and carry out degassed.
In the situation of this 5th embodiment, the control part 150 of refrigerator 101 is always set in bypass path 145 sides by water intaking valve 160, only to storage part, 137 is just being switched to degasser 136 sides while supplying water.
Therefore, in the situation that water intaking valve 160 breaks down and can not be switched to water supply path 126 side, that is, even under the state being closed at water supply path 126, current are supplied to ice-making disc 114 through bypass path 145.So, same with the 4th embodiment, can from water supply path 126, overflow by anti-sealing.
Especially, water intaking valve 160 also forms branching portion 162.For example, in the situation that by branching portion 162 be arranged on water intaking valve 160 above, when water intaking valve 160 breaks down, have the danger of hydropexis between water intaking valve 160 and branching portion 162.
Therefore, using water intaking valve 160 as triple valve, by one side is connected to, assist bypass pipe portion 161, can prevent that thus hydropexis is in the part of the upstream side of water intaking valve 160.
In addition, in Figure 19, represented that the water intaking valve 160 that consists of triple valve and auxiliary bypass pipe portion 161 form the example of bypass path 145, but, can certainly as the 4th embodiment have further from the bypass pipe portion 142 (with reference to Figure 18) of interim storage part 134 branches.
(the 6th embodiment)
Water supply path, degasser, the bypass path of the 6th embodiment are described based on Figure 20.In the 6th embodiment, the exhaust side of drawdown pump is connected with bypass pipe portion, this point is different from the 4th embodiment.In addition, the main composition of the 6th embodiment is identical with the 4th embodiment.
In the water supply path 126 and bypass path 145 of the 6th embodiment, as shown in figure 20, the exhaust outlet 139b of drawdown pump 139, is connected with bypass pipe portion 142 via auxiliary bypass pipe portion 170.
For example, in the situation that feed water valve 138 breaks down, when in storage part, 137 inside is filled by water, drawdown pump 139 has is not only the danger that air water also sucks.In this situation, exhaust outlet 139b is when opening in the reception room 133 (with reference to Figure 133) of refrigerator 101, and the water of suction flows out in reception room 133.
Therefore, in the present embodiment, the exhaust outlet 139b of drawdown pump 139 is connected with bypass pipe portion 142 via auxiliary bypass pipe portion 170.Thus, even break down and storage part 137 is filled by water at feed water valve 138, in the situation that drawdown pump 139 sucks this water, this water is also supplied to ice-making disc 114.So, can prevent that hydropexis is in reception room 133 is interior.
