Description

The control method of crossing cold refrigerator and crossing cold refrigerator

Technical field

The present invention relates to a kind of refrigerator that makes to comprise the liquid beverage supercooling such as cold drink or drinks and carry out keeping.In more detail, the present invention relates to a kind of control method of crossing cold refrigerator and crossing cold refrigerator that can easily control temperature.

Background technology

In general, by refrigerating plant, take care of the food that comprises fish or meat etc.Refrigerating plant is for the internal temperature of the cooling chamber of sealing is reduced to lower than external temperature, so that the device of long preservation reserve.Described refrigerating plant has the freeze cycle of refrigerant circulation, absorbs thus the cold air that ambient heat generates during the gasification of the cold-producing medium by liquid condition and makes reserve freezing.

It is subzero that this refrigerating plant has the cooling chamber temperature of food to be controlled at storage, thereby make food product refrigeration.So, when the food such as cryogenic freezing keeping meat or fish, the water being included in food will build-up ice.Thus, food increases volume because water build-ups ice, and causes cell to be damaged, or in cell, only has water first to build-up ice and dissociate from tissue, thereby forms separately ice crystal.Therefore, when frozen food thaws, will change original state, thereby lose delicate flavour.

And its temperature difference surperficial and center of food being stored in cooling chamber is very large, so the freezing speed at food surface and center is different.Thus, from the surface of food to be formed centrally ice crystal, the center that therefore more approaches food has more food cells and is damaged.

And the water that can continue to produce food center becomes ice and temperature is risen to again to the phenomenon of freezing point.Therefore the time that the temperature at food center declines is elongated, and therefrom for a long time in maximum ice crystallization generating zone, thereby generate large-scale ice crystal or pipkrake crystallization.The ice crystal so forming destroys food cell, thereby reduces the quality of food.Therefore, after food defrosting, especially as after the food defrostings such as meat or fish, drip juice (Drip) and increase, now nutritional labeling can run off, so its taste deterioration.

In order to address this is that, the temperature that proposes to have the surfusion utilized to control cooling chamber makes the overcooled technology of reserve.

Cross cold (super cooling) and refer to, though solution or solid cooled below the phase transition temperature under poised state, the phenomenon also not changing.Material all has the stable state that is applicable to this temperature at different temperature, when temperature gradually changes, and the composed atom of this material variations in temperature that can follow up when keeping stable state at each temperature.But, when temperature changes suddenly, therefore composed atom does not have plenty of time to change into stable state at each temperature, can produce the phenomenon of still holding the stable state under initial temperature, or part is changed into and in the way of the state under final temperature, stopped the phenomenon that changes.

For example, when making water cooling gradually, even if being down to 0 ℃, temperature can not solidify at short notice below yet.But, when being in supercooled state, object will become quasi-stationary state, and trickle stimulation also can be broken its unsettled poised state, easily becomes more stable state.That is,, when throwing in this material of a fritter or rocking liquid suddenly in subcooled liquid, get started and solidify and make fluid temperature rise to condensation point, and keep stable poised state at this temperature.

In order to make food supercooling, need to regulate temperature conditions and keep constantly this temperature.Yet refrigerating plant is in the past difficult to control according to the supercooling temperature condition of food the temperature of cooling chamber, be especially difficult to keep equably the Temperature Distribution in cooling chamber, therefore require to address this is that.

In addition, known have a kind of technology make liquid beverage with liquid condition supercooling below condensation point, by this liquid beverage being applied impact, make it moment and be frozen into freezing fruit syrup state.Yet, make liquid beverage for example, with the overcooled temperature range of liquid condition limited (, alcoholic beverage is-10 ℃～-18 ℃).When the temperature of liquid beverage is during lower than aforementioned critical-temperature, in refrigerator, freeze.Therefore,, in order to make liquid beverage in a plurality of containers all with suitable degree supercooling, the temperature in refrigerator need to be remained in described critical temperature range equably.And overcooled liquid beverage is easily subject to the impact of variations in temperature, even temperature is raised several degrees, when being poured on cup etc., be also difficult to be frozen into freezing fruit syrup state.Therefore, be necessary to suppress the variations in temperature in refrigerator, so that temperature keeps stable.So, developing and be used for making the overcooled multiple technologies of liquid beverage.

Yet technology in the past, when becoming actual product, fails normally to realize refrigerator temperature homogenising and temperature stabilization, exist in fact and be difficult to make liquid beverage supercooling the long-term problem that keeps this state, therefore need badly and address this problem.

Below, the control procedure of crossing cold refrigerator of this enforcement is described with reference to Figure 15.Following refrigerator control procedure be take the refrigerator of the first embodiment shown in Fig. 1 and is described as example.Certainly, the control procedure of the refrigerator of other embodiment is also identical.

When this refrigerator 100 drives, by temperature sensor 41, detected the internal temperature of cooling chamber 12.The temperature value detecting by temperature sensor 41 is applied to controller 42.The actual temperature value of 42 pairs of cooling chambers that detect 12 of controller compares with the set temperature value of record in storage part 46.

In described storage part 46, record the temperature range for the supercooling temperature of control storage thing, and according to reserve, by the operating portion 4 being connected with controller 42, change this temperature range if desired.

In the present embodiment, in described storage part 46, the temperature range of storage is divided into for determining whether supply the first temperature range of cold air and for controlling the second temperature range of cold air temperature.When departing from the first temperature range, controller 42 supplies or stop cold air itself.In described the second temperature range, described controller 42 is controlled to the temperature of the cold air of cooling chamber 12 supplies, in order to avoid the internal temperature of cooling chamber 12 sharply declines along with the supply of cold air.

The first temperature range is set to reserve to remain the temperature range of supercooled state.In the present embodiment, described the first temperature range is set to 0 ℃～-20 ℃ of the supercooling temperature scopes of fish or meat.Described the second temperature range is set to the first temperature range with interior temperature.For example, described the second temperature range can be set to the temperature of 80% scope of the first temperature range.That is,, when described the first temperature range is 0 ℃～-20 ℃, the second temperature range is set between-2 ℃～-18 ℃.

42 pairs of temperature values that detect of controller compare with the first predetermined temperature range, when the temperature detecting is the higher limit of the first temperature range when above, to cooling chamber 12, supply cold air.When induced-draught fan 23 drives according to the control signal of controller 42, to the inside of cooling pipe 23, suck the inner air of cooling chamber 12.And when compressor 24 drives, by heat exchanger 21, carry out heat exchange to form cold air.Cold air sprays to supply line 31 by being arranged on the driving for blower fan 32 of the outlet side of cooling pipe 22.The cold air that is fed to supply line 31 moves to top along supply line 31, and by being formed on the hole 33 of supply line 31, sprays to the inside of cooling chamber 12, and the internal temperature of cooling chamber 12 is reduced to the supercooling temperature scope of reserve.Thus, the reserve loading on rack 16 becomes supercooled state in cooling chamber 12.

Described controller 42 continues to detect the temperature of cooling chamber 12 inside, and relatively and calculate the temperature that detects whether lower than the higher limit of the second temperature range.When the temperature detecting is the higher limit of the second temperature range when above, continue repeatedly to carry out described process, when higher limit lower than the second temperature range, control cold air temperature.

The process of controlling cold air temperature is by controlling the air output that produced by the driving for blower fan 32 and mixing drum blower fan 43 or the driving by heater 45 realizes.

When controller 42 drives heater 45, the cold air blowing to supply line 31 is rising via temperature in being arranged on the process of the heater 45 in supply line 31.The cold air rising by heater 45 temperature to the inside supply of cooling chamber 12 thus.Because like this control by heater 45 promotes cold air temperature and this cold air is fed to cooling chamber 12, so the internal temperature of cooling chamber 12 can sharply not decline, but is rendered as the state that declines slowly.Therefore can more continue and stably keep the supercooling temperature to reserve.In addition, elongated the time interval for the driving of the compressor 24 of cold air supply and between stopping, thereby the on/off frequently that can reduce to greatest extent due to compressor 24 drives the fault causing, also can prevent from forming frost at heat exchanger simultaneously.

Controller 42, except driving heater 45, also drives mixing drum blower fan 43 to control cold air temperature.When mixing drum blower fan drives, the part in the inner air of cooling chamber 12 can directly not be inhaled into supply line 31 by mixing drum blower fan 43 through cooling pipe 22.At the cold air through cooling pipe 22, under the state of supply line 31 supplies, along with supplying to supply line 31 without the inner air cooling and cooling chamber 12 that temperature is higher than cold air temperature as above, cold air and air mix in supply line 31.Thus, the air that cold air is high with temperature mixes, thereby makes temperature increase.Therefore the temperature mixing air higher than cold air is fed to the inside of cooling chamber 12.Because the driving by mixing drum blower fan 43 like this promotes cold air temperature and is supplied to cooling chamber 12, so can be in the situation that do not have the sharply change of temperature to continue and stably keep the supercooling temperature to reserve, and can not make supercooling temperature produce variation sharply.

Wherein, the air output that described controller 42 passes through to control the air output of described mixing drum blower fan 43 and supplies blower fan 32, thus can more critically control the temperature of mixing cold air.For example, when needs change cold air temperature more lentamente, can make the air output of mixing drum blower fan 43 be greater than the air output for blower fan 32, thereby increase the air capacity of mixing with cold air.Thus, more than the amount of the cold air that the amount of air blows to supply line 31, can more promote the temperature of mixing cold air.So by the air output of adjusting cold air and air, carry out the temperature of accurate control mixing cold air, thus the variation that can more slowly and constantly keep the internal temperature of cooling chamber 12.

In addition, controller 42 judges whether the internal temperature of the cooling chamber 12 by detecting after cold air temperature control procedure as above departs from the lower limit of the second temperature range.When controller 42 judges that the temperature detecting departs from the lower limit of the second temperature range, stop the control to cold air temperature.Along with the control stopping cold air temperature, cold gas is directly fed to cooling chamber 12.Thus, the internal temperature of cooling chamber 12 sharply declines, and whether the temperature that controller 42 judgements detect departs from the lower limit of the first temperature range, stops cold air supply when departing from the lower limit of the first temperature range.

By controller 42, stop the driving of compressor 24 and each blower fan, blocked to the cold air of cooling chamber 12 supplies.Stop after cold air supply, the internal temperature of cooling chamber 12 rises gradually.Controller 42 continues to detect the internal temperature of cooling chamber 12 by temperature sensor 41.Internal temperature and first temperature range of 42 pairs of cooling chambers that detect 12 of controller compare and calculate, and when temperature value rises to the higher limit of the first temperature range when above, restart cold air supply.

By the control to cold air temperature as above, can according to the supercooling temperature conditional stability of reserve keep the internal temperature of cooling chamber 12.

The preferred embodiments of the present invention have more than been described, but the present invention is not limited to above-described embodiment.In the open scope of claims and description and Figure of description, various forms is implemented in deformable, and undoubtedly this also belongs to protection scope of the present invention.
