At first, if electric power to be applied to refrigerator 1, then carbonated water preparation is set to dead status by refrigerator 1, and prepares in the 301b of viewing area in the carbonated water that carbonated water prepares information display unit 301 and show carbonated water preparation and be deactivated (OFF), as shown in (a) in Fig. 8.
User by carbonated water prepare instruction input unit 303 to refrigerator 1 input carbonated water preparation enable instruction to start carbonated water preparation or input carbonated water preparation stop using instruction come inactive carbonated water preparation.In detail, if user presses for a long time or touches carbonated water prepare the state be deactivated in carbonated water under prepare instruction input unit 303, then refrigerator 1 starts carbonated water preparation.In addition, refrigerator 1 carbonated water prepare in the 301b of viewing area show carbonated water preparation be activated (ON), and prepare in the 301a of concentration viewing area in carbonated water " first order " or " low concentration " that show as initial value, as shown in (b) in Fig. 8.
If user to prepare under the state be activated long-time pressing or touches carbonated water in carbonated water prepare instruction input unit 303, then refrigerator 1 is stopped using carbonated water preparation prepare in the 301b of viewing area in carbonated water and show carbonated water preparation and be deactivated (OFF).
In addition, user prepares instruction input unit 303 to select the concentration of carbonated water by carbonated water.In detail, if user to prepare under the state be activated short time pressing or touches carbonated water in carbonated water prepare instruction input unit 303, then refrigerator 1 makes the concentration of the carbonated water of preparation increase one-level.Namely, when the concentration of carbonated water for " first order " or " low concentration " and if time user's short time press or touch carbonated water and prepare instruction input unit 303, then refrigerator 1 makes the concentration of carbonated water be increased to " second level " or " intermediate concentration ", and prepare display " second level " or " intermediate concentration " in the 301a of concentration viewing area, as shown in (c) in Fig. 8 in carbonated water.When the concentration of carbonated water for " second level " or " intermediate concentration " and if time user's short time press or touch carbonated water and prepare instruction input unit 303, then refrigerator 1 makes the concentration of carbonated water be increased to " third level " or " high concentration ".But, when the concentration of carbonated water for " third level " or " high concentration " and if time user's short time press or touch carbonated water and prepare instruction input unit 303, then refrigerator 1 makes the concentration of carbonated water be reduced to " first order " or " low concentration ".
When carbonated water prepared by refrigerator 1, refrigerator 1 is prepared in the 301c of situation viewing area to show in carbonated water and is prepared carbonated water, as shown in (d) in Fig. 8.
As mentioned above, the configuration of the refrigerator 1 of Fig. 1 has been described in detail.
Below, the refrigerator 1 of Fig. 1 is used to prepare carbonated water by describing.Refrigerator 1 prepares carbonated water prepare the state be activated in carbonated water under, and does not prepare carbonated water prepare the state be deactivated in carbonated water under.
Fig. 9 A and Fig. 9 B is the view that the situation of carbonated water prepared by the refrigerator 1 schematically showing Fig. 1.
Briefly describing with reference to Fig. 9 A and Fig. 9 B uses the refrigerator 1 of Fig. 1 to prepare carbonated water, and in order to prepare carbonated water, first filtered water is fed to carbonic acid water tank 110 by refrigerator 1, then carbon dioxide is fed to carbonic acid water tank 110.Then, the time of scheduled volume waited for by refrigerator 1, until the carbon dioxide of supply dissolves in filtered water.
The situation of filtered water supplied by the refrigerator 1 that Fig. 9 A shows Fig. 1 to carbonic acid water tank 110, if the opened drainage supply valve 211 of refrigerator 1, then filtered water is supplied flow path 210 and moved and be supplied to carbonic acid water tank 110 from water tank 70 along filtered water, as shown in Figure 9 A.
The situation of carbon dioxide supplied by the refrigerator 1 that Fig. 9 B shows Fig. 1 to carbonic acid water tank 110, if carbon dioxide supply valve 202 opened by refrigerator 1, the carbon dioxide then discharged from carbon dioxide storage tank 120 is depressurized by carbon dioxide adjuster 201, and post-decompression carbon dioxide moves along carbon dioxide supply flow path 200 and is supplied to carbonic acid water tank 110.
Like this, be supplied to the carbon dioxide solubility of carbonic acid water tank 110 in filtered water, thus can carbonated water be prepared.
Below, the method using the refrigerator 1 of Fig. 1 to prepare carbonated water will be described in detail.
If user inputs carbonated water prepare instruction, then the refrigerator 1 of Fig. 1 manually can prepare carbonated water, if meet predetermined condition, then the refrigerator 1 of Fig. 1 automatically can prepare carbonated water.In addition, user is by via control panel, (300, in fig. 8) input is prepared instruction fast and prepares carbonated water fast.
Figure 10 illustrates that the refrigerator 1 of Fig. 1 is prepared instruction in response to the carbonated water of user and starts to prepare the flow chart of the situation of carbonated water.
With reference to Figure 10, first, refrigerator 1 determines whether user have input carbonated water and prepare enabled instruction (680).As mentioned above, user can press or touch the carbonated water be arranged in control panel 300 for a long time and prepare instruction input unit 303, thus input carbonated water prepares enabled instruction.
If determine that have input carbonated water prepares enabled instruction ("Yes" of 680), then refrigerator 1 determines whether to prepare carbonated water (682).This is because, in order to prepare carbonated water, when user carbonated water prepare to input under the state be activated carbonated water preparation stop using instruction then input carbonated water prepare enabled instruction time, carbonated water is prepared enabled instruction and can be transfused to when preparing carbonated water.
If determine that carbonated water preparation is carried out ("Yes" of 682), then refrigerator 1 restarts the preparation (686) of ongoing carbonated water.
If determine that carbonated water preparation is not carried out ("No" of 682), then refrigerator 1 starts the preparation (684) of carbonated water.
Like this, if user inputs carbonated water prepare the state be deactivated in carbonated water under prepare enabled instruction, then refrigerator 1 starts or restarts the preparation of carbonated water.
Figure 11 is the flow chart illustrating that the refrigerator 1 of Fig. 1 starts to prepare the situation of carbonated water by determining whether to prepare carbonated water.
With reference to Figure 11, first, refrigerator 1 initializes accumulative carbonated water drain time (610).Accumulative carbonated water drain time refers to the total time being made refrigerator 1 emission of carbon sour water after carbonated water is produced by the distributor mechanism bar 93 of operation setting in distributor mechanism 90.Because carbonated water is discharged with constant speed by carbonated water adjuster 232, therefore estimate the amount of remaining carbonated water in carbonic acid water tank 110 by accumulative carbonated water drain time.
Next, refrigerator 1 initializes carbonated water discharge instruction latencies (615).Carbonated water discharge instruction latencies has referred to from institute's elapsed time since having discharged carbonated water by operation distributor mechanism bar 93.
Next, refrigerator 1 determines whether user have input carbonated water discharge instruction (620).As mentioned above, user inputs carbonated water discharge instruction by pressing the distributor mechanism bar 93 that is arranged in distributor mechanism 90.
If user have input carbonated water discharge instruction ("Yes" of 620), then refrigerator 1 opens carbonated water drain valve 231 and emission of carbon sour water (622).As mentioned above, if open carbonated water drain valve 231, then by the pressure of carbonic acid water tank 110 with constant speed emission of carbon sour water.Then, refrigerator 1 determines whether to have input carbonated water discharge command for stopping (624), and closes carbonated water drain valve (626) when have input carbonated water discharge command for stopping ("Yes" of 624).
While emission of carbon sour water, refrigerator 1 calculates carbonated water drain time (630).In detail, refrigerator 1 can calculate the opening time of carbonated water drain valve 231 or the operating time of distributor mechanism bar 93, thus calculates carbonated water drain time.
Next, refrigerator 1 upgrades (635) accumulative carbonated water drain time.In detail, refrigerator 1 can be stored in the carbonated water drain time and current accumulative carbonated water drain time sum that calculate in step 630, thus upgrades accumulative carbonated water drain time.
Like this, whenever emission of carbon sour water, refrigerator 1 all can calculate carbonated water drain time, and can upgrade accumulative carbonated water drain time based on the carbonated water drain time calculated.Refrigerator 1 is estimated having prepared the carbonated water discharge capacity after carbonated water by the accumulative carbonated water drain time calculated, and estimates remaining carbonated water surplus in carbonic acid water tank 110 by carbonated water discharge capacity.
Then, refrigerator 1 uses level sensor 111 to sense the water level (640) of carbonated water.Like this, when user inputs carbonated water discharge instruction, refrigerator 1 senses the water level of carbonated water.This is because, level sensor 11 senses the water level of carbonated water based on the current value flowed between multiple electrode, if level sensor 111 senses the water level of carbonated water constantly, then producing bubble due to the chemical reaction between carbonated water and electrode at surrounding them, therefore occur mistake when sensing water level.In order to prevent level sensor 111 maloperation, the water level of refrigerator 1 sensing carbonated water when user inputs carbonated water discharge instruction.
In addition, the water level of the carbonated water of sensing and lowest water level compare (645) by refrigerator 1, if the water level of the carbonated water of sensing is less than or equal to lowest water level ("Yes" of 645), then refrigerator 1 starts the preparation (650) of carbonated water.That is, the amount of remaining carbonated water in carbonic acid water tank 110 after having discharged carbonated water measured by refrigerator 1, if the amount of remaining carbonated water is lower than reference value, then refrigerator 1 starts the preparation of carbonated water.
If the water level of the carbonated water of sensing is higher than lowest water level ("No" of 645), then refrigerator 1 turns back to step 615, and initializes carbonated water discharge instruction latencies (615).Owing to having discharged carbonated water in response to carbonated water discharge instruction, therefore make carbonated water discharge instruction latencies and initialized.
If do not input carbonated water discharge instruction ("No" of 620) in step 620, then refrigerator 1 calculates carbonated water discharge instruction latencies (655).Then, carbonated water is discharged instruction latencies and predetermined maximum latency compares (660) by refrigerator 1.As comparative result, if carbonated water discharge instruction latencies is more than or equal to predetermined maximum latency ("Yes" of 660), then accumulative carbonated water drain time and predetermined largest cumulative drain time compare (665) by refrigerator 1, if accumulative carbonated water drain time is more than or equal to predetermined largest cumulative drain time ("Yes" of 665), then refrigerator 1 starts the preparation of carbonated water.
As mentioned above, carbonated water discharge instruction latencies refers to institute's elapsed time after user inputs carbonated water discharge instruction.Like this, carbonated water discharge instruction latencies is greater than predetermined maximum latency and means that user has not used carbonated water or user temporarily will not use carbonated water for a long time.In addition, the discharge capacity of carbonated water and the surplus of carbonated water are estimated by accumulative carbonated water drain time.
Like this, if anticipating user is not temporarily by inputting carbonated water discharge instruction and determining to have discharged the carbonated water of scheduled volume, then need to prepare carbonated water in addition.Namely, when being lowest water level to prevent the water level when carbonated water and preparing carbonated water, user waits for carbonated water, if even if the water level being stored in the carbonated water in carbonic acid water tank 110 is not less than lowest water level and anticipating user temporarily will not use carbonated water, then refrigerator 1 still can prepare carbonated water.
Therefore, refrigerator 1 carbonated water is discharged instruction latencies and maximum discharge instruction latencies compares to determine whether there is and will drink the user view of carbonated water, accumulative carbonated water drain time and largest cumulative drain time are compared the amount estimating remaining carbonated water in carbonic acid water tank 110, therefore, if anticipating user temporarily will not input carbonated water discharge instruction and in carbonic acid water tank 110, remaining carbonated water is lower than scheduled volume, then refrigerator 1 starts the preparation of carbonated water.
If carbonated water discharge instruction latencies is more than or equal to maximum discharge instruction latencies and accumulative carbonated water drain time is more than or equal to largest cumulative drain time, then the refrigerator 1 of Fig. 1 starts the preparation of carbonated water.But each side of the present disclosure is not limited thereto, and if accumulative carbonated water drain time is more than or equal to largest cumulative drain time, then refrigerator 1 can start the preparation of carbonated water.
Figure 12 illustrates the view using the refrigerator 1 of Fig. 1 to prepare the method for carbonated water.
With reference to Figure 12, the refrigerator 1 of Fig. 1 can be prepared three kinds of concentration (such as the first order, the second level and the third level) (low concentration, intermediate concentration and high concentration)) carbonated water, and the concentration of carbonated water is different according to the supply number of times of carbon dioxide.
In detail, in order to prepare the carbonated water with first order concentration (low concentration), refrigerator 1 supplies the filtered water of maximum stage to carbonic acid water tank 110, then in the first carbon dioxide supply time section (such as, 6 seconds) in supply carbon dioxide to carbonic acid water tank 110, and within the first carbon dioxide solubility time period (such as, 4 minutes), dissolve the carbon dioxide of supply.
In addition, in order to prepare the carbonated water with second level concentration (intermediate concentration), refrigerator 1 performs the process that preparation has the carbonated water of first order concentration (low concentration), then in the second carbon dioxide supply time section (such as, 4 seconds) in supply carbon dioxide to carbonic acid water tank 110, and within the second carbon dioxide solubility time period (such as, 8 minutes), dissolve the carbon dioxide of supply.
In addition, in order to prepare the carbonated water with third level concentration (high concentration), refrigerator 1 performs the process that preparation has the carbonated water of second level concentration (intermediate concentration), then in the 3rd carbon dioxide supply time section (such as, 5.5 seconds) in supply carbon dioxide to carbonic acid water tank 110, the 3rd carbon dioxide solubility time period (such as, 12 minutes) the interior carbon dioxide dissolving supply, and carbon dioxide is supplied to carbonic acid water tank 110 in the 4th carbon dioxide supply time section (such as, 5.5 seconds).

With reference to Figure 13 A and Figure 13 B, first, refrigerator 1 shows prepares carbonated water (710).In detail, refrigerator 1 can be prepared in the 301c of situation viewing area to show in carbonated water and prepares carbonated water, as shown in (d) in Fig. 8.
Then, air bleeding valve 251 (712) opened by refrigerator 1, then opened drainage supply valve 211 (714).Like this, refrigerator 1 opens air bleeding valve 251 and opened drainage supply valve 211, makes filtered water can be fed to carbonic acid water tank 110 swimmingly.In this case, refrigerator 1 sustainably opened drainage supply valve 211 so that filtered water is fed to carbonic acid water tank 110.
When using magnetic valve as filtered water supply valve 211, in order to prevent overheat of solenoid valve, then can be opened time of scheduled volume of filtered water supply valve 211 can be closed, the time of the scheduled volume that then can be opened again.In detail, can repeat filtered water supply valve 211 is opened the process that then filtered water supply valve 211 cut out for 5 seconds by 1 minute.
Then, refrigerator 1 senses the water level (716) of filtered water by level sensor 111, the water level of the filtered water of sensing and predetermined peak level are compared, to determine whether the filtered water in carbonic acid water tank 110 reaches peak level (718).
If determine that the filtered water in carbonic acid water tank 110 reaches peak level ("Yes" of 718), then refrigerator 1 is closed filtered water supply valve 211 (720) and is closed air bleeding valve 251 (722).
Then, carbon dioxide supply valve 202 (724) opened by refrigerator 1, then the first carbon dioxide supply time is determined (such as, 6 seconds) whether pass by (726), if determine the first carbon dioxide supply time (such as, 6 seconds) pass by, then refrigerator 1 closing carbon dioxide supply valve 202 (728).Like this, in the first carbon dioxide supply time section (such as, 6 seconds), refrigerator 1 allows carbon dioxide to be supplied to carbonic acid water tank 110.
Then, refrigerator 1 waits for (730) within the first carbon dioxide solubility time period (such as, 4 minutes).That is, refrigerator 1 allows the carbon dioxide being supplied to carbonic acid water tank 110 to be fully dissolved in filtered water.
Then, refrigerator 1 determines whether the concentration of user-selected carbonated water is " first order (low concentration) " (732).
If user is the first order (low concentration) ("Yes" of 732) by the concentration of the carbonated water selected by control panel 300, then the preparation that refrigerator 1 shows carbonated water completes (758), and stops the preparation of carbonated water.
If the concentration of user-selected carbonated water is not the first order (low concentration) ("No" of 732), then carbon dioxide supply valve 202 (734) opened by refrigerator 1, and determine since carbon dioxide supply valve 202 is opened, whether to have pass by the second carbon dioxide supply time (such as, 4 seconds) (736), if determine the second carbon dioxide supply time (such as, 4 seconds) pass by ("Yes" of 736), then refrigerator 1 closing carbon dioxide supply valve 202 (738).Like this, carbon dioxide is fed to carbonic acid water tank 110 by refrigerator 1 in the second carbon dioxide supply time section (such as, 4 seconds).
Then, refrigerator 1 waits for (740) within the second carbon dioxide solubility time period (such as, 8 minutes).That is, refrigerator 1 allows the carbon dioxide being supplied to carbonic acid water tank 110 to be fully dissolved in filtered water.
Then, refrigerator 1 determines whether the concentration of user-selected carbonated water is " second level (intermediate concentration) " (742).
If determine that the concentration of user-selected carbonated water is the second level (intermediate concentration) ("Yes" of 742), then the preparation that refrigerator 1 shows carbonated water completes (758), and stops the preparation of carbonated water.
If determine that the concentration of user-selected carbonated water is not the second level (intermediate concentration) ("No" of 742), then carbon dioxide supply valve 202 (744) opened by refrigerator 1, and determine since carbon dioxide supply valve 202 is opened, whether to have pass by the 3rd carbon dioxide supply time (such as, 5.5 seconds) (746), if determine the 3rd carbon dioxide supply time (such as, 5.5 seconds) pass by ("Yes" of 746), then refrigerator 1 closing carbon dioxide supply valve 202 (748).Like this, carbon dioxide is fed to carbonic acid water tank 110 by refrigerator 1 in the 3rd carbon dioxide supply time section (such as, 5.5 seconds).
Then, refrigerator 1 waits for (750) within the 3rd carbon dioxide solubility time period (such as, 12 minutes).That is, refrigerator 1 allows the carbon dioxide being supplied to carbonic acid water tank 110 to be fully dissolved in filtered water.
Then, carbon dioxide supply valve 202 (752) opened by refrigerator 1, and determine since carbon dioxide supply valve 202 is opened, whether to have pass by the 4th carbon dioxide supply time (such as, 5.5 seconds) (754), if determine the 4th carbon dioxide supply time (such as, 5.5 seconds) pass by ("Yes" of 754), then refrigerator 1 closing carbon dioxide supply valve 202 (756).Like this, carbon dioxide is fed to carbonic acid water tank 110 by refrigerator 1 in the 4th carbon dioxide supply time section (such as, 5.5 seconds).
Then, the preparation that refrigerator 1 shows carbonated water completes (758), and stops the preparation of carbonated water.
When preparing carbonated water, although the temperature of filtered water do not considered by the refrigerator of Fig. 11 when meeting predetermined carbonated water prepares beginning condition just preparation carbonated water, the disclosure is not limited thereto.According to another embodiment, can consider the temperature of filtered water and prepare carbonated water, this is because reduce along with the temperature of liquid, gas improves relative to the dissolubility of liquid.Such as, after inherent filtration water is supplied to carbonic acid water tank 110, the temperature of the filtered water be stored in carbonic acid water tank 110 measured by the refrigerator 1 of Fig. 1, if the temperature being stored in the filtered water in carbonic acid water tank 110 is greater than or equal to predetermined temperature, then refrigerator 1 postpones the supply of carbon dioxide.As mentioned above, because carbonic acid water tank 110 is arranged in refrigerating chamber 20, the temperature being therefore stored in the filtered water in carbonic acid water tank 110 reduces in time.Therefore, if the temperature of the filtered water measured is less than or equal to predetermined temperature, then refrigerator 1 can supply carbon dioxide to prepare carbonated water.
Utilizing said method in this case, refrigerator 1 can use as much as possible and be stored in carbon dioxide in carbon dioxide storage tank 120 to prepare carbonated water, but need to wait for that carbon dioxide solubility is in filtered water, cause cost a large amount of time to prepare carbonated water.If user wishes to use carbonated water in addition after the carbonated water in carbonic acid water tank 110 consumes completely, then before carbonated water completes, user needs to wait for a large amount of time.For this reason, refrigerator 1 needs the quick preparation performing carbonated water.
Figure 14 illustrates according to the view preparing fast the method for carbonated water in the refrigerator of embodiment of the present disclosure.
With reference to Figure 14, filtered water supplied by refrigerator 1 until the peak level of carbonic acid water tank 110, and the step that the carbon dioxide supply valve 202 repeating to be opened by the air bleeding valve 251 being used for discharging the carbon dioxide remained in carbonic acid water tank 110 and be used for carbon dioxide to be fed to carbonic acid water tank 110 is opened.Along with the supply of carbon dioxide and discharge are performed repeatedly, carbonated water is prepared very quickly.
In detail, carbon dioxide supply flow path 200 (see Fig. 5) deeply extends to the inside of carbonic acid water tank 110, if supply carbon dioxide, then in the filtered water of carbonic acid water tank 110, produces bubble, thus stirs carbon dioxide and filtered water.In addition, the carbon dioxide of supply is more, and the dissolving occurred between filtered water and carbon dioxide is more, and therefore carbon dioxide is dissolved in filtered water rapidly.Like this, the increase through the amount of the carbon dioxide of filtered water allows to prepare carbonated water rapidly.
In order to increase the amount of the carbon dioxide through filtered water, refrigerator 1 supplies carbon dioxide to carbonic acid water tank 110 after making the reduction of the pressure of carbonic acid water tank 110 inside.Because carbon dioxide is supplied to carbonic acid water tank 110 because of carbon dioxide adjuster 201 with constant pressure (such as, 8.5 bar), therefore the reduction of the internal pressure of carbonic acid water tank 110 allows more substantial carbon dioxide to be supplied to carbonic acid water tank 110.
In addition, refrigerator 1 is opened air bleeding valve 251 and is reduced to make the pressure of carbonic acid water tank 110 inside.That is, by opening air bleeding valve 251, discharge remains in the carbon dioxide of carbonic acid water tank 110 inside to refrigerator 1, and therefore makes the pressure of carbonic acid water tank 110 inside reduce.
Then, in order to supply carbon dioxide to carbonic acid water tank 110, carbon dioxide supply valve 202 is opened.If the pressure in carbonic acid water tank 110 inside supplies carbon dioxide after reducing, then a large amount of carbon dioxide is through filtered water, and therefore a large amount of carbon dioxide solubilities is in filtered water.
By repeating the step of supplying carbon dioxide/discharge from carbonic acid water tank 110 carbon dioxide to carbonic acid water tank 110, refrigerator 1 can prepare carbonated water rapidly.
Figure 15 A and Figure 15 B is the quick flow chart preparing the method for carbonated water that Figure 14 is shown.
The method preparing carbonated water is fast described in detail with reference to Figure 15 A and Figure 15 B.First, refrigerator 1 determines whether have input and prepares instruction (1010) fast.User prepares instruction fast by instruction input unit (307 in Fig. 7) input of preparing fast of control panel 300.
Prepare instruction ("Yes" of step 1010) fast if having input, then refrigerator 1 shows the quick preparation (1015) of carbonated water.In detail, refrigerator 1 prepares by control panel 300 the quick preparation that information display unit (309 in Fig. 7) shows carbonated water fast.Quick preparation instruction so not only can be transfused to when not preparing carbonated water and also can be transfused to when preparing carbonated water.If input prepares instruction fast when not preparing carbonated water, then refrigerator 1 opens air bleeding valve 251 to supply filtered water until the peak level of carbonic acid water tank 110, then closes air bleeding valve 251.That is, refrigerator 1 supply filtered water until carbonic acid water tank 110 peak level after start to prepare carbonated water.Meanwhile, if input prepares instruction fast when preparing carbonated water, then refrigerator 1 stops preparation carbonated water, and starts quick preparation immediately.
Then, refrigerator 1, opening air bleeding valve 251 (1035) with reference in evacuation time section, then closes air bleeding valve 251 (1040).In this case, about 0.5 second to about 5 seconds can be set as with reference to evacuation time, and can change according to the supply pressure (that is, the blowdown presssure of carbon dioxide adjuster 201) of the capacity of carbonic acid water tank 110 or carbon dioxide with reference to evacuation time.Like this, during preparing carbonated water, instruction is prepared in input fast, at the front opening air bleeding valve 251 (as mentioned above) of supply carbon dioxide, with the carbon dioxide of emission of carbon sour water case 110 inside.That is, when during preparing carbonated water, instruction is prepared in input fast, carbon dioxide can keep high pressure in carbonic acid water tank 110, therefore discharges carbon dioxide and the pressure of carbonic acid water tank 110 inside is reduced.
Then, refrigerator 1 opens carbon dioxide supply valve 202 (1045) at carbon dioxide fast supply time durations, then closing carbon dioxide supply valve 202 (1050).The carbon dioxide fast supply time can be set as about 0.5 second to about 10 seconds, and can change according to the supply pressure (that is, the blowdown presssure of carbon dioxide adjuster 201) of the capacity of carbonic acid water tank 110 or carbon dioxide.Like this, if the pressure in carbonic acid water tank 110 inside supplies carbon dioxide to carbonic acid water tank 110 after reducing, then as described above, a large amount of carbon dioxide is supplied to carbonic acid water tank 110, and in the carbon dioxide process that supply is a large amount of, carbon dioxide and filtered water are stirred, thus carbon dioxide is easily dissolved in filtered water.
Then, refrigerator 1 can wait for the predetermined reference stand-by period (1052), and the described predetermined reference stand-by period represents the waiting step before the carbon dioxide solubility being fed to carbonic acid water tank 110 is in filtered water.The reference stand-by period like this can be set as about 1 second to about 10 seconds, and can change according to the supply pressure (that is, the blowdown presssure of carbon dioxide adjuster 201) of the capacity of carbonic acid water tank 110 or carbon dioxide.
Then, refrigerator 1, again opening air bleeding valve 251 (1055) with reference in evacuation time, then closes air bleeding valve 251 (1060).Therefore, supply in step 1045 being discharged with reference to not being dissolved in filtered water the carbon dioxide remained in carbonic acid water tank 110 in the stand-by period.Along with residual carbon dioxide is discharged, refrigerator 1 makes the pressure of carbonic acid water tank 110 inside reduce.
Then, the pre-determined number (1065) whether the number of times of carbon dioxide supply reaches carbon dioxide and inject fast determined by refrigerator 1.As mentioned above, supply carbon dioxide when the pressure of carbonic acid water tank 110 inside is low and a large amount of carbon dioxide is dissolved in filtered water, but in order to prepare the carbonated water expecting concentration, the confession of carbon dioxide is in requisition for being repeated quickly and easily as many times as required.That is, the number of times that carbon dioxide injects fast can be set differently according to the expectation concentration of carbonated water.Such as, when user's instruction prepares carbonated water with the first order of carbonated water or low concentration, the pre-determined number that carbon dioxide injects fast can be set to once to twice by refrigerator 1, when user's instruction prepares carbonated water with the second level of carbonated water or intermediate concentration, the pre-determined number that carbon dioxide injects fast can be set to three times to four times by refrigerator 1.In addition, when user's instruction prepares carbonated water with the third level of carbonated water or high concentration, the pre-determined number that carbon dioxide injects fast can be set to more than five times by refrigerator 1.
If the number of times of carbon dioxide supply does not reach the pre-determined number ("No" of step 1065) that carbon dioxide injects fast, then refrigerator 1 repeats to supply the step of carbon dioxide/discharge from carbonic acid water tank 110 carbon dioxide in carbonic acid water tank 110.
If the number of times of carbon dioxide supply reaches the pre-determined number ("Yes" of step 1065) that carbon dioxide injects fast, then refrigerator 1 opens carbon dioxide supply valve 202 (1070) at carbon dioxide fast supply time durations, then closing carbon dioxide supply valve 202 (1075).In this case, the pressure of carbonic acid water tank 110 inside, to make carbon dioxide solubility in filtered water, is remained on constant level by the supply performing carbon dioxide simultaneously.That is, the supply of carbon dioxide is performed as and makes when user inputs carbonated water discharge instruction by distributor mechanism bar 93, and refrigerator 1 carrys out emission of carbon sour water by utilizing the pressure of carbonic acid water tank 110 inside.
Like this, by repeating to supply the step of carbon dioxide/discharge from carbonic acid water tank 110 carbon dioxide in carbonic acid water tank 110, refrigerator 1 such as prepares carbonated water fast within a few minutes.
Below, the operation of refrigerator 1 under exception (situation of the such as user input filterd water discharge instruction when preparing carbonated water or when preparing carbonated water user open the situation of refrigerating-chamber door 21 and 22) will be described in.
When preparing carbonated water, particularly when filtered water being fed to carbonic acid water tank 110, if user presses distributor mechanism bar 93 and inputs filtered water discharge instruction, then refrigerator 1 stops supplying filtered water to carbonic acid water tank 110, and passes through distributor mechanism 90 by filtered water discharge to outside.
Be supplied to the filtered water of carbonic acid water tank 110 and be discharged into outside filtered water by distributor mechanism 90 and supplied by water tank 70, the hydraulic pressure of the filtered water when filtered water supplied by water tank 70 is limited.Therefore, if water tank 70 supplies filtered water to carbonic acid water tank 110, simultaneously by distributor mechanism 90 exhaust filtering water, then the hydraulic pressure of the filtered water of being discharged by distributor mechanism 90 can be reduced.Like this, if the hydraulic pressure of the filtered water of being discharged by distributor mechanism 90 is reduced, then user may think that refrigerator 1 is bad by mistake.
Like this, reduce to prevent the hydraulic pressure of the filtered water of being discharged by distributor mechanism 90, if the user input filterd water discharge instruction when filtered water being fed to carbonic acid water tank 110, then refrigerator 1 stops supplying filtered water to carbonic acid water tank 110, and by distributor mechanism 90 exhaust filtering water.Then, if user input filterd water discharge command for stopping, then refrigerator 1 stops by distributor mechanism 90 exhaust filtering water, and filtered water is fed to carbonic acid water tank 110.
In addition, if user opens refrigerating-chamber door 21 and 22 when preparing carbonated water, then refrigerator 1 stops preparation carbonated water.Namely, if user opens refrigerating-chamber door 21 and 22 when filtered water being fed to carbonic acid water tank 110, then refrigerator 1 stops supplying filtered water to carbonic acid water tank 110, if user opens the refrigerating-chamber door 21 and 22 being wherein provided with carbonated water and preparing module 100 when carbon dioxide being fed to carbonic acid water tank 110, even if then meet the condition of supplying carbon dioxide to carbonic acid water tank 110, refrigerator 1 still postpones to supply carbon dioxide, until user's closing cold room door 21 and 22.In addition, refrigerator 1 stops supplying carbon dioxide to carbonic acid water tank 110.Because filtered water is fed to carbonic acid water tank 110 and carbon dioxide is under high pressure fed to carbonic acid water tank 110 by carbon dioxide storage tank 120 by water tank 70 at high water pressures, therefore noise can be produced in the process of preparation carbonated water.Like this, when user opens refrigerating-chamber door 21 and 22, can bring offending impression to user, in addition, user may think that refrigerator 1 is bad by mistake.
Like this, produce noise to prevent from preparing in module 100 in carbonated water when user opens refrigerating-chamber door 21 and 22, then the process that refrigerator 1 stores preparation carbonated water stops the preparation of carbonated water.If user's closing cold room door 21 and 22, then refrigerator 1 continues preparation carbonated water.
Figure 16 A and Figure 16 B illustrates the flow chart when there are abnormal conditions during carbonated water preparation to the control of the refrigerator 1 of Fig. 1.
With reference to Figure 16 A and Figure 16 B, first, refrigerator 1 shows the preparation (902) of carbonated water on display floater 300.
Then, air bleeding valve 251 (904) opened by refrigerator 1, opened drainage supply valve 211 (906), thus filtered water is fed to carbonic acid water tank 110.
When filtered water being fed to carbonic acid water tank 110, refrigerator 1 determines whether to have input filtered water discharge instruction (908).That is, refrigerator 1 determines whether user has pressed the distributor mechanism bar 93 be arranged in distributor mechanism 90.
If determine that user have input filtered water discharge instruction ("Yes" of 908), then refrigerator 1 stores the situation (940) preparing carbonated water.
Then, filtered water supply valve 211 (942) closed by refrigerator 1, to stop supplying filtered water to carbonic acid water tank 110, and the opened drainage drain valve 221 (944) of refrigerator 1, with by filtered water discharge to outside.
When by filtered water discharge to time outside, refrigerator 1 determines whether to have input filtered water discharge command for stopping (946).That is, refrigerator 1 determines whether user stops pressing the distributor mechanism bar 93 be arranged in distributor mechanism 90.
If determine that user have input filtered water discharge command for stopping ("Yes" of 946), then filtered water discharge valve 221 (948) closed by refrigerator 1, to stop filtered water discharge to outside, and the opened drainage supply valve 211 (950) of refrigerator 1, to restart the preparation of carbonated water and to load carbonated water and prepare progress situation (952).
If determine that user does not input filtered water discharge instruction ("No" of 908), then refrigerator 1 determines whether refrigerating-chamber door 21 and 22 is opened (910).
If determine that user opens refrigerating-chamber door 21 and 22 ("Yes" of 910), then refrigerator 1 stores the situation (930) preparing carbonated water.
Then, filtered water supply valve 211 (932) closed by refrigerator 1, to stop the preparation of carbonated water.
Then, refrigerator 1 determines whether refrigerating-chamber door 21 and 22 is closed (934).
If determine that refrigerating-chamber door 21 and 22 is closed ("Yes" of 934), then the opened drainage supply valve 211 (936) of refrigerator 1, to restart the preparation of carbonated water and to load carbonated water and prepare progress situation (938).
If user does not open refrigerating-chamber door 21 and 22 ("No" of 910), then refrigerator 1 senses the water level (912) of the filtered water in carbonic acid water tank 110.
Then, refrigerator 1 determines whether the water level of the filtered water in carbonic acid water tank 110 reaches peak level (914).
If determine that the water level of the filtered water in carbonic acid water tank 110 does not reach peak level ("No" of 914), then refrigerator 1 repeats to determine whether to have input filtered water discharge instruction, whether refrigerating-chamber door 21 and 22 is opened and whether the water level of filtered water in carbonic acid water tank 110 reaches the step of peak level.
If determine that the water level of the filtered water in carbonic acid water tank 110 reaches peak level ("Yes" of 914), then refrigerator 1 is closed filtered water supply valve 211 (916) and is closed air bleeding valve 251 (918), thus stops supplying filtered water to carbonic acid water tank 110.
Then, carbon dioxide supply valve 202 (920) opened by refrigerator 1, thus carbon dioxide is fed to carbonic acid water tank 110.
When carbon dioxide being fed to carbonic acid water tank 110, refrigerator 1 determines whether refrigerating-chamber door 21 and 22 is opened (922).
If determine that refrigerating-chamber door 21 and 22 is opened ("Yes" of 922), then refrigerator 1 stores the situation (960) preparing carbonated water.
Then, refrigerator 1 closing carbon dioxide supply valve 202 (962), thus the preparation stopping carbonated water.
Then, refrigerator 1 determines whether refrigerating-chamber door 21 and 22 is closed (964).
If determine that refrigerating-chamber door 21 and 22 is closed ("Yes" of 964), then carbon dioxide supply valve 202 (966) opened by refrigerator 1, to restart the preparation of carbonated water and to load carbonated water and prepare progress situation (968).
If determine that refrigerating-chamber door 21 and 22 is not opened ("No" of 922), then refrigerator 1 determines whether carbon dioxide supply time goes over (924).
If determine that carbon dioxide supply time is not pass by, then refrigerator 1 repeats the step of determining whether refrigerating-chamber door 21 and 22 is opened and whether carbon dioxide supply time goes over.
If determine that carbon dioxide supply time is pass by, then refrigerator 1 closing carbon dioxide supply valve 202 (926).
Then, refrigerator 1 determines whether the carbon dioxide solubility time goes over (928).
If determine that the carbon dioxide solubility time passes by, then the preparation that refrigerator 1 shows carbonated water on control panel 300 completes (929).
As mentioned above, carbonated water prepared by the refrigerator 1 having described use Fig. 1.
Below, the management to the carbonated water of preparation from carbonated water prepared by the refrigerator 1 of Fig. 1 will be described.
As mentioned above, refrigerator 1 utilization of Fig. 1 is supplied to the pressure of the carbon dioxide of carbonic acid water tank 110 and carbonated water is discharged into outside.Therefore, the pressure of the carbon dioxide in carbonic acid water tank 110 needs to be maintained at more than predetermined value or predetermined value.If the pressure of the carbon dioxide in carbonic acid water tank 110 is not maintained at more than predetermined value or predetermined value, then the hydraulic pressure of the carbonated water of being discharged by refrigerator 1 is reduced, and user may think that refrigerator 1 is bad by mistake.
But after carbonated water is produced as time goes by, carbon dioxide solubility is in filtered water, and the pressure of carbon dioxide in carbonic acid water tank 110 reduces gradually.Therefore, if meet the predetermined condition of the pressure for maintaining the carbon dioxide in carbonic acid water tank 110, then need carbon dioxide to be fed to carbonic acid water tank 110.
The main cause that the pressure of the carbon dioxide in carbonic acid water tank 110 is reduced has three.
First reason that the pressure of the carbon dioxide in carbonic acid water tank 110 is reduced is: the temperature of carbonated water reduces.Gas increases along with the reduction of the temperature of liquid relative to the dissolubility of liquid.Along with the reduction of the temperature of carbonated water, the amount being dissolved in the carbon dioxide in filtered water increases.Therefore, along with the reduction of the temperature of carbonated water, the pressure of the carbon dioxide in carbonic acid water tank 110 reduces.Therefore, if the temperature of the carbonated water in carbonic acid water tank 110 reduces, then carbon dioxide is fed to carbonic acid water tank 110 by refrigerator 1.
Figure 17 A illustrates that the flow chart of the situation of carbon dioxide supplied again by the refrigerator 1 of Fig. 1 to carbonic acid water tank 110 according to the temperature of carbonated water.
With reference to Figure 17 A, first, refrigerator 1 determines whether the preparation of carbonated water completes (812).
If determine that the preparation of carbonated water not yet completes ("No" of 812), then refrigerator 1 is waited for until the preparation of carbonated water completes, if the preparation of carbonated water completes ("Yes" of 812), then refrigerator 1 senses the temperature (813) of carbonated water by temperature sensor 112, and the difference between the temperature of the carbonated water sensed in step 813 and predetermined temperature interval is set to reference temperature (814) by refrigerator 1.That is, the reference temperature preparation be initialized to immediately preceding carbonated water complete after difference between the temperature of carbonated water and predetermined temperature interval.Such as, if the temperature of carbonated water is 15 DEG C and temperature interval is 5 DEG C, then reference temperature is initialized to 10 DEG C.
Then, refrigerator 1 senses the temperature (815) of carbonated water by temperature sensor 112.
Then, the temperature of the carbonated water of sensing in step 815 and reference temperature compare by refrigerator 1, and determine that whether the temperature of carbonated water is less than or equal to reference temperature (816).Such as, refrigerator 1 determines that whether the temperature of carbonated water is less than or equal to 10 DEG C.
If determine that the temperature of carbonated water is less than or equal to reference temperature ("Yes" of 816), then carbon dioxide supply valve 202 (818) opened by refrigerator 1, determine carbon dioxide again supply time whether pass by (820), if determine carbon dioxide again supply time pass by ("Yes" of 820), then refrigerator 1 closing carbon dioxide supply valve 202 (822).That is, if determine that the temperature of carbonated water is less than or equal to reference temperature, then refrigerator 1 supplies carbon dioxide again to carbonic acid water tank 110 in carbon dioxide again supply time.In this case, carbon dioxide again supply time can be set as 1 second.In this case, because supply carbon dioxide is not the internal pressure for the preparation of carbonated water but for maintaining carbonic acid water tank 110, therefore the comparable carbon dioxide supply time for the preparation of carbonated water of supply time is short again for carbon dioxide.
After carbon dioxide is fed to carbonic acid water tank 110 again, refrigerator 1 is set to new reference temperature (824) by deducting the value that temperature interval obtains from reference temperature.Such as, if reference temperature is 10 DEG C and temperature interval is 5 DEG C, then new reference temperature is 5 DEG C.
If determine that the temperature of carbonated water is not that then refrigerator 1 omits step carbon dioxide being fed to again carbonic acid water tank 110 less than or equal to reference temperature ("No" of 816) in step 816.
Then, refrigerator 1 determines whether to meet carbonated water preparation condition (826), if the preparation of carbonated water does not start, then refrigerator 1 turns back to step 815, and the temperature of repeat sensing carbonated water and step that the temperature of carbonated water and reference temperature are compared.
Therefore, when the preparation of carbonated water completes the temperature of carbonated water reduce described temperature interval so much time, carbon dioxide is all fed to carbonic acid water tank 110 by refrigerator 1 again.Such as, if the temperature of carbonated water is 15 DEG C and the first temperature interval is 5 DEG C when the preparation of carbonated water completes, then whenever the temperature of carbonated water be 10 DEG C, 5 DEG C and 0 DEG C time, carbon dioxide is all fed to carbonic acid water tank 110 by refrigerator 1 again.
When the temperature being stored in the carbonated water in carbonic acid water tank 110 reduces predetermined temperature, carbon dioxide is all fed to carbonic acid water tank 110 by the refrigerator 1 of Fig. 1 again.But each side of the present disclosure is not limited thereto, when the temperature being stored in the carbonated water in carbonic acid water tank 110 is less than or equal to predetermined temperature, carbon dioxide can be fed to carbonic acid water tank 110 by refrigerator 1 again.
Second reason that the pressure of the carbon dioxide in carbonic acid water tank 110 reduces is: the amount of the carbonated water in carbonic acid water tank 110 reduces.If user is emission of carbon sour water after the preparation of carbonated water has completed, then the volume of carbonated water decreases the amount of the carbonated water be discharged by user, and the pressure of the carbon dioxide therefore in carbonic acid water tank 110 reduces.Therefore, if user's emission of carbon sour water, then carbon dioxide is fed to carbonic acid water tank 110 by refrigerator 1 again, increases to make the pressure of the carbon dioxide in carbonic acid water tank 110.
Figure 17 B illustrates that the flow chart of the situation of carbon dioxide supplied again by the refrigerator 1 of Fig. 1 when carbonated water is discharged to carbonic acid water tank 110.
With reference to Figure 17 B, first, refrigerator 1 determines whether the preparation of carbonated water completes (832).
If determine that the preparation of carbonated water not yet completes ("No" of 832), then refrigerator 1 is waited for until the preparation of carbonated water completes, if determine that the preparation of carbonated water completes ("Yes" of 832), then refrigerator 1 stores predetermined very first time interval (834) with the first reference time.That is, the first reference time was initialized to predetermined very first time interval.In this case, very first time interval changes according to the capacity of carbonic acid water tank 110 and the mass rate of emission of carbonated water.But be discharged in 1 minute if carbonic acid water tank 110 is about 1 liter and all carbonated waters be stored in carbonic acid water tank 110, then very first time interval can be set as 10 seconds.That is, the first reference time can be initialized to 10 seconds.
Then, accumulative carbonated water drain time and the first reference time compare by refrigerator 1, and determine whether the carbonated water drain time added up is more than or equal to the first reference time (836).Here, accumulative carbonated water drain time refers to user operation after carbonated water is produced and is arranged on the total time that the distributor mechanism bar 93 in distributor mechanism 90 makes carbonated water be discharged.That is, accumulative carbonated water drain time is identical with the accumulative carbonated water drain time shown in Figure 11.As mentioned above, in carbonic acid water tank 110, the amount of remaining carbonated water is estimated by accumulative carbonated water drain time.
If determine that the carbonated water drain time added up is more than or equal to the first reference time ("Yes" of 836), then carbon dioxide supply valve 202 (838) opened by refrigerator 1, and determine carbon dioxide again supply time whether pass by (840), if determine carbon dioxide again supply time pass by ("Yes" of 840), then refrigerator 1 closing carbon dioxide supply valve 202 (842).That is, if be more than or equal to for the first reference time by the time of user's emission of carbon sour water, then carbon dioxide is fed to carbonic acid water tank 110 again by refrigerator 1 in carbon dioxide again supply time section.In this case, carbon dioxide again supply time can be set as 1 second.As mentioned above, for maintaining the carbon dioxide of the pressure in carbonic acid water tank 110, the comparable carbon dioxide supply time for the preparation of carbonated water of supply time is short again.
After carbon dioxide is fed to carbonic acid water tank 110 again, the first reference time and very first time interval sum are set to the new reference time (844) by refrigerator 1.Such as, if the first reference time was 10 seconds and the very first time is spaced apart 10 seconds, then the first new reference time is 20 seconds.
If determine that in step 836 accumulative carbonated water drain time is not be more than or equal to the first reference time ("No" of 836), then refrigerator 1 omits step carbon dioxide being fed to again carbonic acid water tank 110.
Then, refrigerator 1 determines whether to meet carbonated water working condition (846), if the preparation of carbonated water does not start, then refrigerator 1 turns back to step 836, and repeats the step that accumulative carbonated water drain time and the first reference time compared.
Therefore, when making the carbonated water drain time added up increase very first time interval after having completed in the preparation of carbonated water because of user's emission of carbon sour water, carbon dioxide is all fed to carbonic acid water tank 110 by refrigerator 1 again.Such as, if the very first time be spaced apart 10 seconds, then whenever accumulative carbonated water drain time be 10 seconds, 20 seconds, 30 seconds, 40 seconds and 50 seconds time, carbon dioxide is all fed to carbonic acid water tank 110 by refrigerator 1 again.
The 3rd reason that the pressure of the carbon dioxide in carbonic acid water tank 110 is reduced is: carbonated water is not used but by long-time storage in carbonic acid water tank 110.If carbonated water is not discharged after being produced but by long-time storage in carbonic acid water tank 110, then carbon dioxide is dissolved in carbonated water gradually, and the pressure of the carbon dioxide in carbonic acid water tank 110 is reduced.Therefore, if user there is no emission of carbon sour water and carbonated water by long-time storage in carbonic acid water tank 110, then carbon dioxide is fed to carbonic acid water tank 110 by refrigerator 1 again, increases to make the pressure of the carbon dioxide in carbonic acid water tank 110.
Figure 17 C illustrates that carbon dioxide is fed to the flow chart of the situation of carbonic acid water tank 110 by the refrigerator 1 of Fig. 1 when carbonated water is not discharged again.
With reference to Figure 17 C, first, refrigerator 1 determines whether the preparation of carbonated water completes (852).
If determine that the preparation of carbonated water not yet completes ("No" of 852), then refrigerator 1 is waited for until the preparation of carbonated water completes, if determine that the preparation of carbonated water completes ("Yes" of 852), then refrigerator 1 stores predetermined second time interval (854) with the second reference time.That is, the second reference time was initialized to the second predetermined time interval.In this case, second time interval changed according to the capacity of carbonic acid water tank 110.But if carbonic acid water tank 110 is about 1 liter, then second time interval can be set as 2 hours.That is, the second reference time can be initialized to 2 hours.
Then, carbonated water is discharged instruction latencies by refrigerator 1 and the second reference time compared, and determines whether carbonated water discharge instruction latencies is more than or equal to the second reference time (856).Here, carbonated water discharge instruction latencies refer to from user operation distributor mechanism bar 93 and carbonated water since being discharged up to now till institute's elapsed time.That is, to discharge instruction latencies identical for carbonated water discharge instruction latencies and the carbonated water shown in Figure 11.
If determine that carbonated water discharge instruction latencies is more than or equal to the second reference time ("Yes" of 856), then carbon dioxide supply valve 202 (858) opened by refrigerator 1, then determine carbon dioxide again supply time whether pass by (860), if determine carbon dioxide again supply time pass by ("Yes" of 860), then refrigerator 1 closing carbon dioxide supply valve 202 (862).That is, if user does not have the time of emission of carbon sour water to be more than or equal to for the second reference time, then carbon dioxide is fed to carbonic acid water tank 110 again by refrigerator 1 in carbon dioxide again supply time section.In this case, carbon dioxide again supply time can be set as 1 second.As mentioned above, for maintaining the carbon dioxide of the pressure in carbonic acid water tank 110, the comparable carbon dioxide supply time for the preparation of carbonated water of supply time is short again.
After carbon dioxide is fed to carbonic acid water tank 110 again, the second reference time and the second time interval sum are set to the new reference time (864) by refrigerator 1.Such as, if the second reference time was 2 hours and second time interval was 2 hours, then the second new reference time is 4 hours.
If determine that in step 856 carbonated water discharge instruction latencies is not be more than or equal to the second reference time ("No" of 856), then refrigerator 1 omits step carbon dioxide being fed to again carbonic acid water tank 110.
Then, refrigerator 1 determines whether to meet carbonated water preparation condition (866), if the preparation of carbonated water does not start, then refrigerator 1 turns back to step 856, and repeats carbonated water to discharge the step that instruction latencies and the second reference time compare.
Therefore, when making carbonated water discharge instruction latencies increase by second time interval after having completed in the preparation of carbonated water because user does not have emission of carbon sour water, carbon dioxide is all fed to carbonic acid water tank 110 by refrigerator 1 again.Such as, if second time interval was 2 hours, then whenever carbonated water discharge instruction latencies is 2 hours, 4 hours, 6 hours, 8 hours and 10 constantly little, carbon dioxide is all fed to carbonic acid water tank 110 by refrigerator 1 again.
As mentioned above, the filtered water for the preparation of carbonated water is supplied by watering, and carbon dioxide is supplied by carbon dioxide storage tank 120, and the amount being stored in the carbon dioxide in carbon dioxide storage tank 120 is limited.
First, reduce if be stored in the depleted and pressure that the is carbon dioxide of discharge from carbon dioxide storage tank 120 of most of carbon dioxide in carbon dioxide storage tank 120, then the concentration of carbonated water reduces.That is, owing to being supplied to the quantity not sufficient of the carbon dioxide of carbonic acid water tank 110, therefore the concentration of carbonated water reduces.Then, if all carbon dioxide be stored in carbon dioxide storage tank 120 are depleted, then carbonated water cannot be prepared.
In addition, if the pressure of the carbon dioxide of discharge reduces from carbon dioxide storage tank 120, then distributor mechanism 90 emission of carbon sour water cannot be passed through.As mentioned above, carbonated water is discharged into outside by the air pressure in carbonic acid water tank 110, if the pressure of carbon dioxide reduces, then refrigerator 1 supplies carbon dioxide again to keep with making the pressure uniform of the carbon dioxide in carbonic acid water tank 110.In this case, if the pressure of the carbon dioxide of discharge reduces from carbon dioxide storage tank 120, even if then when carbon dioxide is fed to carbonic acid water tank 110 again, the pressure of the carbon dioxide in carbonic acid water tank 110 also cannot remain on enough pressure, if the pressure of the carbon dioxide in carbonic acid water tank 110 reduces, then distributor mechanism 90 emission of carbon sour water cannot be passed through.
Therefore, need to change carbon dioxide storage tank 120 with predetermined time interval.Therefore, the refrigerator 1 of Fig. 1, by the pressure of pressure sensor 204 senses carbon dioxide, if the pressure of the carbon dioxide of sensing is less than or equal to predetermined reference pressure, then shows and changes carbon dioxide storage tank 120 on control panel 300.
Figure 18 is the flow chart of the situation of the pressure of refrigerator 1 senses carbon dioxide that Fig. 1 is shown.
With reference to Figure 18, first, refrigerator 1 is by the pressure (870) of pressure sensor 204 senses carbon dioxide.As mentioned above, pressure sensor 204 is arranged on the output of carbon dioxide adjuster 201, and sensing is from the pressure of the carbon dioxide of carbon dioxide adjuster 201 discharge.
Then, the pressure of carbon dioxide and predetermined reference pressure compare by refrigerator 1, and determine that whether the pressure of carbon dioxide is less than or equal to reference pressure (872).
If determine that the pressure of carbon dioxide is not less than or equal to reference pressure ("No" of 872), the then pressure of refrigerator 1 senses carbon dioxide, and repeat the step that the pressure of the carbon dioxide of sensing and reference pressure compared.
If determine that the pressure of carbon dioxide is less than or equal to reference pressure ("Yes" of 872), then refrigerator 1 warns the pressure of user's carbon dioxide to reduce (874).That is, refrigerator 1 is being arranged on reminding user to replace dioxide bottle 120 in the carbon dioxide low pressure viewing area 305 in control panel 300.In addition, if the pressure of carbon dioxide is less than or equal to reference pressure, then refrigerator 1 can stop the preparation of carbonated water.
In addition, if determine that the pressure of carbon dioxide is less than or equal to reference pressure, even if then meet above-mentioned carbonated water preparation condition, refrigerator 1 also can not prepare carbonated water.Such as, even if when the water level of carbonated water is less than or equal to lowest water level, refrigerator 1 also can not prepare carbonated water.
When using pressure switch as pressure sensor 204, the output of pressure switch is connected to display unit, if the pressure of carbon dioxide is less than or equal to reference pressure, then low-voltage signal can be transferred to display unit by pressure switch, and display unit can show the low pressure of carbon dioxide in carbon dioxide low pressure viewing area 305.
As mentioned above, the refrigerator 1 of Fig. 1 is prepared and manages carbonated water.
Below, use the refrigerator 1 of Fig. 1 according to the instruction emission of carbon sour water of user by describing.
If user presses the distributor mechanism bar 93 that is arranged in distributor mechanism 90 and input carbonated water discharge instruction, then refrigerator 1 is by opening carbonated water drain valve 231 and emission of carbon sour water, if user stops pressing distributor mechanism bar 93 and inputs carbonated water discharge command for stopping, then refrigerator 1 stops emission of carbon sour water by closing carbonated water drain valve 231.
Figure 19 is the view of the situation of the refrigerator 1 emission of carbon sour water schematically showing Fig. 1.
With reference to Figure 19, if user inputs carbonated water discharge instruction, then the refrigerator 1 of Fig. 1 is by distributor mechanism 90 emission of carbon sour water.In detail, if carbonated water drain valve 231 opened by refrigerator 1, then carbonated water is moved from carbonic acid water tank 110 along carbonated water discharge flow path 230, and in this process, carbonated water stops valve 241 to be discharged into outside via carbonated water adjuster 232, carbonated water drain valve 231 and residual water discharge.
Figure 20 is the schematic diagram of the situation of the refrigerator 1 emission of carbon sour water that Fig. 1 is shown.
With reference to Figure 20, refrigerator 1 determines whether to have input carbonated water discharge instruction (880) by user.As mentioned above, user presses the distributor mechanism bar 93 that is arranged in distributor mechanism 90 and inputs carbonated water discharge instruction.
If have input carbonated water discharge instruction ("Yes" of 880), then residual water discharge prevention valve 241 (882) opened by refrigerator 1, and then carbonated water drain valve 231 (884) opened by refrigerator 1.
Like this, when emission of carbon sour water, first open residual water discharge and stop valve 241, then open carbonated water drain valve 231, stop valve 241 impaired to prevent residual water discharge.
Generally speaking, residual water discharge stops valve 241 to be discharged for preventing the residual water in integral type discharge flow path 240, and is not designed to withstand high pressure.That is, compared with carbonated water drain valve 231, residual water discharge stops valve 241 easily can damage because of the blowdown presssure of carbonated water.In addition, when there is a large amount of carbon dioxide be not dissolved in carbonated water in carbonic acid water tank 110, the blowdown presssure of carbonated water can increase.When the carbonated water of maximum discharge pressure is transferred to suddenly residual water discharge prevention valve 241, residual water discharge prevention valve 241 may be impaired.
Then, refrigerator 1 determines whether to have input carbonated water discharge command for stopping (886).As mentioned above, user inputs carbonated water discharge command for stopping by stopping pressing distributor mechanism bar 93.
If have input carbonated water discharge command for stopping ("Yes" of 886), then carbonated water drain valve 231 (888) closed by refrigerator 1, then closes residual water discharge and stops valve 241 (890).
Like this, when carbonated water discharge stops, first close carbonated water drain valve 231, then close residual water discharge and stop valve 241, stop valve 241 to damage to prevent residual water discharge.That is, if close residual water discharge while emission of carbon sour water to stop valve 241, then residual water discharge prevention valve 241 may be impaired because of the blowdown presssure of carbonated water.
Therefore, when emission of carbon sour water, open residual water discharge and stop valve 241, then open carbonated water drain valve 231, when carbonated water discharge stops, close carbonated water drain valve 231, then close residual water discharge and stop valve 241, thus can prevent residual water discharge from stoping valve 241 to damage.
According to spirit of the present disclosure, optionally take out filtered water and carbonated water, because carbon dioxide is by the carbonic acid water tank of periodic sale to storage carbonated water, therefore carbonated water is discharged with constant pressure.
According to spirit of the present disclosure, repeat to supply carbon dioxide/from the step of carbonic acid water tank discharge carbon dioxide in carbonic acid water tank, thus prepare carbonated water fast.
Although illustrate and described embodiments more of the present disclosure, but skilled person will appreciate that, without departing from the principles and spirit of the present invention, can change these embodiments, scope of the present invention is limited in claim and equivalent thereof.
