Abstract
A frost resistant freezer includes a freezer chamber, a door, a cooler, and a desiccant. The freezer chamber has a volume. The door provides access to the freezer chamber. The cooler cools air within the freezer chamber from a first temperature within the chamber immediately following closure of the door to a second, quiescent temperature during a cooling period. The desiccant is disposed within the freezer chamber and is selected to absorb moisture from the freezer chamber at a rate sufficient to reduce the relative humidity within the freezer chamber to a value low enough to prevent the formation of frost within the freezer chamber at the quiescent temperature.
Description
[0001] priority of U.S. Provisional Patent Application is advocated in patent application of the present invention, and the application number of this U.S. Provisional Patent Application is 60/795,638, and denomination of invention is a defrosting device for refrigerator.
[technical field]
[0002] invention relates to and a kind ofly reduces moisture in an enclosure space, refers in particular to a kind of apparatus and method that can reduce the formation and the defrosting of the frost on refrigerator cold-storage chamber internal surface and the reserve effectively.
[background technology]
[0003] well-known, indoor process a period of time of refrigerator cold-storage can form frost usually, and As time goes on, increasing frost is accumulated on the inner surface and reserve of refrigerating chamber, has significantly reduced available space in the refrigerating chamber.Even frost can influence the taste of food loss or make some food variable colors.Correspondingly, the user is glad to adopt these methods to remove frost in refrigerating chambers, as adding the technology of hot thing in toward refrigerating chamber, with ice pick ice is broken into pieces or the like.Though frost has been removed,, problem is not still solved, because frost accumulation again after a time, defrost process need repeat.
[0004] except aforesaid drawback, the existence of frost also may bring extra, negative influence to refrigerator.The frost that long-time accumulation forms might stop up air ventilation holes, and it is excessive to cause the compressor of refrigerator and other members to be loaded on the whole, causes that the energy consumes excessively, low usefulness and might damaging.If more frost is accumulated, frost is dangerous just as vice, probably enters in the mechanical organ of refrigerator, finally damages refrigerator.Each final result in these schemes causes too much energy bills, the maintenance of costliness or the replacement of whole refrigerator to I haven't seen you for ages.
[0005] frost in the refrigerator normally forms by following dual mode: first kind of mode realizes that by opening refrigerator when refrigerator was opened, warm moist air relative in the external environment condition poured in refrigerator inside.Because the inside and outside huge temperature difference of refrigerator, pour in aqueous vapor in the warm moist air of refrigerator inside and run into the low temperature mist formation that condenses rapidly.When refrigerator is closed, mist is had nowhere to go but slowly is attached on the arbitrary surfaces in the refrigerator, and final accumulation forms one deck ice or frost.
[0006] Shuan another source is to form in sublimation process.Typically, when article such as ice cube were placed in the refrigerator, moisture distilled from these article, was frozen into frost again and was attached to other article surfaces in the refrigerator.
[0007] frost in the refrigerator is a known problem, and the Defrost method of two standards is arranged at present.Yet any one is not effective especially.
[0008] first kind of Defrost method is traditional method, thereby comprises all article of removing in the refrigerator, turn off power supply and melt the ice.When making in this way, with the means that temperature is arranged, for example hot water, electric frying pan or the like can promote that ice quickens to melt.Certain this Defrost method is unsatisfactory, thereby because it need be removed the article in the refrigerator and reappose those article is unlikely to thaw, and this method is very time-consuming.
[0009] second kind of Defrost method is generally to make " frostless " refrigerator, and when making in this way, the temperature in the refrigerator can improve in the time interval of setting, so that the frost in the refrigerator melts or distillation.This method is more effective, yet needs to install in refrigerator the mechanical organ of additional complexity.This can increase the purchase and the maintenance cost of refrigerator.Owing to require also to need heating cycle, this method to consume the extra energy.
[0010] in sum, the technology that needs to be grasped the method and apparatus that can reduce frost formation is obviously, and this method and apparatus should reduce manually-operated as far as possible and not have additional energy source consumption and corresponding cost.
[summary of the invention]
[0011] the objective of the invention is to satisfy the method for the demand defrosting device for refrigerator to be provided and to use the drier defroster.
[0012] the object of the invention aims to provide a kind of freezer frost on the one hand, and this freezer frost comprises cold compartment of refrigerator, door, condenser and drier.The refrigerating chamber of described refrigerator has certain capacity.Door offers path of cold compartment of refrigerator.Described condenser is used for first temperature of refrigeration indoor air temperature when closing dropped to and is in second static temperature of stablizing the cooling cycle.It is indoor that drier is placed in refrigerator cold-storage, and with enough speed at the indoor moisture that optionally absorbs of refrigerator cold-storage to reduce the indoor relative humidity of refrigerator cold-storage to enough low, in case stagnant ice case refrigerating chamber forms frost when static temperature.
[0013] the object of the invention provides the method that a kind of control has cold compartment of refrigerator and is used for the refrigeration indoor air temperature is reduced to frost accumulation in the refrigerator of condenser of static temperature on the other hand, comprise that the temperature that will refrigerate room air is reduced to the static temperature when first relative humidity, allow warm-humid air to enter refrigerating chamber, and once more the air in the refrigerating chamber is cooled to static temperature, reduces the relative humidity of refrigeration room air simultaneously.
[0014] with reference to accompanying drawing of the present invention and detailed description of the present invention subsequently, feature of the present invention can better be showed and be understood.
[description of drawings]
[0015] Fig. 1 is the schematic perspective view of better embodiment of the present invention.
[0016] Fig. 2 is that preferred embodiment of the present invention shows the systemic moisture time history plot of the different desiccant material refrigerators of use.
[0017] Fig. 3 has used the systemic moisture time history plot of other desiccant material refrigerator in the other better embodiment.
[specific embodiment]
[0018] with reference to corresponding accompanying drawing, below will be elaborated to several better embodiment of the present invention.
[0019] just as described above, the formation of frost can throw into question in the refrigerator.As shown in Figure 1, refrigerator 2 generally includes one in order to refrigerating chamber 4 that stores food or the like and the cooling device 6 that is communicated with refrigerating chamber 4, and this cooling device 6 roughly remains on freezing point or following in order to temperature that reduces refrigerating chamber 4 and the temperature that is retained to static state.Usually, refrigerating chamber seals basically mutually to external world.Yet, when refrigerating chamber is exposed to the external world, for example, by opening the door 8 of refrigerator 2, seal destroyedly and temperature higher relatively, moisture pours in refrigerating chamber, the interior part air of refrigerating chamber before having replaced.Warm relatively humid gas has formed mist, simultaneously, has improved the temperature of refrigerating chamber 4, causes cooling device 6 must reduce the temperature of the refrigerating chamber that reseals.Because the temperature in the refrigerator 2 is very low, and the relative humidity of air has improved, and if air become saturated, frost will form at refrigerator 2 inner surfaces and/or the surface that stores thing.
[0020] inventor has worked out a kind of method that frost forms that reduces, and particularly, the inventor finds that the moisture in the refrigerator can be absorbed and/or be absorbed by place dry bag 10 in refrigerator before forming mist.Specifically, during cooling device was reduced to static temperature again with the temperature of refrigerating chamber, drier can make the relative humidity in the refrigerator remain on below 100% preferablyly.Suitable drier can reduce the relative humidity in the refrigerator, impels the frost distillation.The distillation of ice usually occurs in refrigerator in the pent short period.Composition absorbs in case distillation, the moisture that distillation forms are dried.
[0021] in better embodiment of the present invention, drier is placed in the sack, for example, and cloth bag or paper bag.This sack is to allow that moisture passes through, thereby the moisture around in the refrigerator can absorb by the sack and the agent that is dried.
[0022] conveniently, the packing of drier comprises adsorbent according to the present invention, and it can be the adsorbent of any amount, and clay, activated clay, macro porous silica gel or gauge orifice silica gel, salt or molecular sieve are contained in the inside.
[0023] table 1 and table 2 show the drier tester absorptivity as time passes of heterogeneity.In table 1, prescription 1 is a clay, the clay that on behalf of two bags of packings, 1 (A) and 1 (B) vary in size.Prescription 2 is a silica gel, the silica gel that on behalf of two bags of packings, 2 (A) and 2 (B) vary in size.Prescription 3 is that a kind of registration mark is TranSorb
Hybrid desiccant, the TranSorb that on behalf of two bags of packings, 3 (A) and 3 (B) vary in size
Drier.Prescription 4 is molecular sieves, the molecular sieve that on behalf of two bags of packings, 4 (A) and 4 (B) vary in size.Table 2 is to be used for illustrating that the 5th prescription comprises 16 unit macro porous silica gels, and 5 in the table (A) refers to the 5th prescription, and 5 (B) refer to 16 unit macro porous silica gels, are used for contrast.
[0024] in above-mentioned test, used the refrigerator that mean temperature is 0 Fahrenheit temperature that has of a calibrated altitude.Extraneous temperature on average is that 77 Fahrenheit temperature and relative humidity are 50%.Shown in each test, all drier are weighed at the very start and are positioned in the refrigerator.Drier is weighed at set intervals then, has absorbed what moisture to determine drier.In " weighing the phase ", that is to say that on the date that dry bag is weighed, the door of refrigerator is opened each three seconds eight times.In the non-phase of weighing at interval,, refrigerator doors is opened three times, each three seconds.The inventor estimates when each refrigerator is opened that nearly 500 milligrams of moistures enter.
[0025] Fig. 1 is that the graphical data of table 1 shows that Fig. 2 is that the graphical data of table 2 is showed, in Fig. 1, prescription 1 to 4 each chart shows is the A that fills a prescription respectively and the mean value of two sample test values of B.
[0026] as table 1 and table 2, illustrated in figures 1 and 2, under refrigerated condition (promptly at about 9 Fahrenheit temperature between negative 5 Fahrenheit temperature), it seems that the gel with vermiculite lasted in the silica gel be the drier of effective adsorption moisture.And the time of the lasting absorption of gel with vermiculite lasted moisture is the longest.At least in 77 day testing period, gauge orifice silica gel is compared with macro porous silica gel, and gauge orifice silica gel has more adsorptivity, this from the table and Fig. 2 as can be seen.
[0027] table 3 and table 2 are roughly the same, and still, what show in the table 3 is that the 6th drier prescription contains 8 unit macro porous silica gels that act on the potassium chloride (Wide Pore Silica Gel, water absorption WPSG) are represented with 6 (A) in table 3.Also chosen 6 (B) i.e., 8 unit silica gel (Silica Gel, SG) thing as a comparison in the table 3.
[0028] according to the present invention, other drier prescriptions also can be used for defrosting, and alternative prescription can comprise the salt of preserving moisture, for example calcium chloride.Adsorbent can mix or immersion with above-mentioned salt.According to the specific embodiment of the present invention, stabilizing agent such as vermiculite or cellulosic material, also can be added in the adsorbent.These stabilizing agents can be preserved the too much material that may be converted into stabilizing solution.One of salt and stabilizing agent or both any combinations can be used.
[0029] extra additive also can be used to reach various effects, for example, moulding easily after binder and resin add, die casting or additive method are to form specific shape.Peculiar smell adsorbent or aromatic additive also can be used.In addition, if environment must be controlled, oxygen absorbent or carbon dioxide absorber or release also can be added, and can excessive influence not arrive validity of the present invention.
[0030] inventor has also tested other prescriptions, and some comprise multiple additives, as mentioned above.Table 4 be one after tested prescription (comprise the prescription 1 to 5, more than describe) inventory.
[0031] result that tests of the prescription that is to use table 4 to list that shows of table 5 and table 6.What particularly, table 5 and table 6 showed is initial weight (unit: restrain) and drier of the same race a series of weight subsequently of drier.According to these weight, those of ordinary skill in the art just can be easy to draw the adsorption rate of each drier.In every kind of drier sample of table 5 and table 6, use all be the refrigerator of calibrated altitude, the mean temperature of refrigerator is 0 Fahrenheit temperature (at-5 Fahrenheit temperature between 9 Fahrenheit temperature).Extraneous temperature on average is 77 Fahrenheit temperature, and relative humidity is 50%, and drier is by in the date of check weighing, and refrigerator is opened eight times, each three seconds.In the non-phase of weighing alternately, refrigerator doors is opened three times, each three seconds.The inventor estimates that when opening refrigerator doors, nearly 500 milligrams moisture enters in the refrigerator at every turn.
[0032] shown in above form, different formulations has different adsorption rates in same refrigerator.Current drying agent optimization formula is a prescription 19, comprises 80% macro porous silica gel and 20% calcium chloride.
[0033] preferably, drier of the present invention can continue to absorb moisture anywhere and reaches about 30 days by about 180 days.When expired the service life that shows on the packaging and so on, drier can be dropped, and changes one bag of new drier.Reach some months the service life of drier, and therefore, the user can remember when to go to change drier easily.
[0034] preferable drier also can be at-5 Fahrenheit temperature between 9 Fahrenheit temperature, and relative humidity is under 45% to 55% the situation, absorb about 20% to 50% the moisture that reaches own wt.Shown in above form, there is the detected prescription of part to reach this scope.
[0035] composition of drier is suitable is contained in the sack.The material of sack should be easy to by the ambient water impervious.Some materials that are fit to are permeable fully, semi permeable, microporous, perhaps porose non-woven material or other acceptable films.At present preferred material is porose non-textile material, as TYVEK
In aforesaid each test, prescription all is positioned in the TYVEK sack.Be understood that easily the porous of sack can have influence on the adsorption capacity of drier composition.Particularly, the hole of sack relatively hour, the be dried speed of agent absorption of moisture aqueous vapor is slower.When not using sack, the adsorption rate maximum of drier.
[0036] although the operating temperature that the sack drying agent is talked about in the front also can about-40 Fahrenheit temperature to about 30 Fahrenheit temperature between, sack drying agent of the present invention is preferably to be used between to about 20 Fahrenheit temperature about-20 Fahrenheit temperature.Drier also can use in relative humidity is environment between about 20% to about 99%, still, preferablyly uses in relative humidity is environment between about 45% to about 55%.According to the different formulations of drier, drier can absorb moisture approximately continue about 30 days by 270 days about.Yet the best time for use of drier is between about 60 days to about 180 days.Use different adsorbents or mixture, raw material, relative humidity and temperature, also be different the service life of drier.
[0037] the present invention uses in the method for optimizing of drier, and the user utilizes one the sack of drier to be housed and sack is placed in the refrigerator.Sack can keep frostless in the refrigerator in the suggestion length of life, and service life is when expiring, the sack that sack is dropped and more renews.
[0038] drier of several different formulations has been described in front, and the selection of the drier of different formulations is used and depended on expected results.For example, according to expection water absorption rate or dry bag expected service life, can select different drier.According to the present invention, when design effective dry bag, need consider following performance, comprise the inside and outside temperature and the inside and outside relative humidity of refrigerator of balanced relative humidity, refrigerator of drier.For example, in some imbodies, keep refrigerator relative humidity can be more suitable for using at the drier of (for example between 90% and 99%) below 100%.In this case, drier can too much not adsorb above keeping frostless necessary moisture.Also expect easily among other embodiment, when the relative humidity in the refrigerator fully is reduced to for example between 40% and 50%, to realize faster and more effective distillation and adsorbed moisture.And as mentioned above, the composition of desiccant package bag also can have some influences to the performance of whole drier.
[0039] although the present invention described above is applicable in the refrigerator that the present invention also can be used on other devices, such device also can use the present invention to reduce the formation of its surperficial condensate or frost.For example, this device also can be used in the air-conditioning duct or the like.
[0040] material of adsorbent can be with Powdered bag or other states of placing.For example, material can be made lattice structure, is positioned over canister inside, forms column by binding, resin or extruding; Perhaps form thin slice or extruding, sintering, be cast into arbitrary shape, perhaps smear in another substrate, perhaps the thin slice of fold again by binding, resin or extruding.Be understandable that the drier of making according to these methods of part does not require with box, bag or this class container package of sealing pouch.
