The specific embodiment
With reference to the non-freezing refrigerator of accompanying drawing detailed description according to preferred implementation of the present invention.
Fig. 3 shows the block diagram according to non-freezing refrigerator of the present invention, and Fig. 4 and Fig. 5 show the structure chart according to the example of non-freezing refrigerator of the present invention.
At length, load sensing unit 20 sensings or the state of store storage space A or B and the state that is stored in the content among memory space A or the B, and sensing result is sent to microcomputer 90.For example, loading sensing unit 20 can be thermometer, is used to store the capacity about memory space A or B--as the state of memory space A or B---information or be used for sensing memory space A or the temperature of B or content; Or hardometer, ammeter, voltmeter, scale, optical pickocff (or laser sensor) or pressure sensor, be used for determining whether content has been stored in memory space A or B.Especially, loading sensing unit 20 can be ammeter or voltmeter.When memory space A or B sky, and when content was stored among memory space A and the B, the resistance that electric field applies had different resistance values.Therefore, whether content has been stored and can have been checked by different resistance values.Microcomputer 90 is according to amount and the moisture of confirming content from the resistance value of loading sensing unit 10, and identification has the kind of the content of moisture.
According to the method for cooling content, freeze cycle 30 can be divided into indirect cooling and directly cooling.Fig. 4 shows the non-freezing refrigerator of indirect cooling type, and Fig. 5 shows the non-freezing refrigerator of direct cooling type, and described refrigerator will be done to explain in detail after a while.
Because the electric field source that is applied to memory space A or B or content by electrode unit 50 is from radio frequency AC voltage, so the polarity of electric field changes along with frequency.Contain O and have+hydrone continuous shaking, rotation and translation of the H of polarity, and when being lower than phase transition temperature, keep liquid phase thus and non-crystallizable by electric field with polarity.
If electric voltage frequency is lower than 1kHz or voltage swing is lower than 500V, the insulating materials that electrode unit 50 can not pass in the housing 110.Even cause the rotation of the hydrone of content according to frequency, speed and vibration also can be a little less than, thereby issue the phase transformation that changes into solid in phase transition temperature.Therefore, voltage generation unit 40 uses the AC voltage of the frequency with radio-frequency range.In addition, the voltage that surpasses 15kV can cause insulation breakdown to non-freezing refrigerator 100.The AC voltage that surpasses 500kHz can not produce electric field in electrode unit 50, and launches with the form of electric wave.Because the pace of change of polarity of voltage is too fast, the motion of hydrone does not catch up with described speed.Therefore, the present invention produces and has used the AC voltage of above-mentioned size and frequency field.The size of voltage and frequency field will be discussed after a while.
Input block 70 can be imported the user to be used for the execution of the non-frozen mode of memory space A or B or content, and is used for that temperature freezing and refrigeration control is set and the selection of the COS (water ice, water or the like) of distributor.In addition, the user can be by the information about content of input block 70 input such as content kinds.Input block 70 can be barcode reader or RFID (RF identification) reader, and it is used for the information about content is provided to microcomputer 90.
Display unit 80 mainly shows the COSs of cryogenic temperature, refrigerated storage temperature and distributors, and shows the current implementation status of non-frozen mode.
According to the present invention, the freezing and refrigeration of microcomputer 90 major controls, and further carry out non-frozen mode.
In addition, microcomputer 90 is from input block 70 or load sensing unit 20 acquisition memory space A or the state of B or the states of content, and produce the AC voltage that has corresponding to the frequency and the size of the message that is obtained or the degree of loading, carry out the non-frozen mode of artificial intelligence thus.
When microcomputer 90 was carried out non-frozen mode, microcomputer 90 can be set or change the non-cryogenic temperature that is used to carry out non-frozen mode.At this, the relation of the energy (being supplied to the energy of content) that microcomputer 90 can apply according to the energy in the cooling of discussing after a while (energy of obtaining from content) with by electric field is set or is changed non-cryogenic temperature.

The non-freezing refrigerator of cooling type comprises indirectly: housing 110, and described housing 110 has an open surfaces, and the shelf 130 that comprises memory space A within it and be used for partly separating memory space A; And door 120, it is used to open and close the open surfaces of housing 110.
The freeze cycle 30 of the non-freezing refrigerator of cooling type comprises indirectly: compressor 32, and it is used for compressed refrigerant; Evaporimeter 33, it is used to produce the cold air (being indicated by arrow) that is used to cool off memory space A or content; Fan 34, it is used to make the cold air forced flow; Suction line 36, it is used for cold air is supplied to memory space A; And discharge pipe 38, it is used for direct cold air makes it pass memory space A and flow to evaporimeter 33.Although not shown, freeze cycle 30 further comprises condenser, drier and expansion cell.
Electrode unit 50a and 50b are formed on towards between the outer surface of the inner surface 112a of memory space A and 112c and housing 110.Electrode unit 50a and 50b are installed as towards memory space A, so that electric field is applied to whole memory space A.Memory space A is along the interior or center position of electrode unit 50a and the 50b end separating with predetermined space and electrode unit 50a and 50b, so that uniform electric field is applied to memory space A or content.
Suction line 36 and discharge pipe 38 are formed on the inner surface 112b of housing 110.Inner surface 112a, 112b and the 112c of housing 110 are made by hydrophobic material, thus because of water surface tension reduce during non-frozen mode, be not frozen.The outer surface of housing 110 and inner surface 112a, 112b and 112c are made by insulating materials, prevent that thus the user is subjected to the electric shock from electrode unit 50a and 50b, and prevent that content from electrically contacting by inner surface 112a, 112b and 112c and electrode unit 50a and 50b.
Identical in the non-freezing refrigerator of the housing 110 in the non-freezing refrigerator of the direct cooling type of Fig. 5, door 120 and shelf 130 and the indirect cooling type of Fig. 4.Except suction line 36 and discharge pipe 38, inner surface 114a, the 114b of housing 110 is identical with inner surface 112a, 112b and the 112c of housing 110 with 114c.
The freeze cycle 30 of the non-freezing refrigerator of the direct cooling type among Fig. 5 comprises: compressor 32, and it is used for compressed refrigerant; And the evaporimeter 39 that is used for vaporized refrigerant, it is mounted in housing 110 round inner surface 114a, 114b and the 114c of memory space B and contiguous housing 110.Directly the freeze cycle 30 of cooling type comprises condenser (not shown) and expansion valve (not shown).
Especially, electrode unit 50a and 50d are inserted between evaporimeter 39 and the housing 110, are stopped by evaporimeter 39 so that prevent cold air.
Fig. 6 and Fig. 7 show cold excessively example view and the chart in non-freezing refrigerator according to the present invention.
Fig. 6 shows experiment structure and the condition of Fig. 7.With reference to figure 7, storage space S is formed in the housing 110 ', and 0.1L distilled water is put into storage space S, thereby and electrode 50e and 50f is inserted in the sidewall of housing 110 ' about the storage space S symmetry.Towards surperficial wide than storage space S of the electrode surface of the electrode 50e of storage surface S and 50f.Between electrode 50e and the 50f is 20mm at interval.Housing 110 is made by acryhic material.Housing 110 is placed in the memory space that is supplied with cold air equably and is cooled off (except electrode 50e and 50f, refrigerating plant does not have extra electric field generator).
At this, microcomputer 90 makes voltage generation unit 40 that the AC voltage of 0.91kV (6.76mA) and 20kHz is applied to electrode unit 50, and the temperature of memory space is approximately-7 ℃.
Shown in the cold chart of the mistake of Fig. 7,, so kept the non-freezing state of water because non-freezing refrigerator 100 produced coldly down being lower than-6.5 ℃ of phase transition temperature.
Fig. 8 and Fig. 9 show the chart of correlation between the electric power and non-cryogenic temperature in according to the non-freezing refrigerator of simplification of the present invention.Fig. 8 and Fig. 9 are applicable to the experiment structure of Fig. 6.It--is internal temperature--that housing 110 is placed on storage temperature (control temperature) in wherein the memory space-be fixed as-6 ℃.At this, microcomputer 90 is set a plurality of amounts of electric energy and it is applied to voltage generation unit 40, and measures the variation of the non-cryogenic temperature that is produced.
Fig. 8 shows the chart of supply with the non-cryogenic temperature of the water of the electric energy of difference amount.As shown in Figure 8, in 0 reference line of not supplying with electric energy, water remains on non-freezing state up to-5 ℃ by cooling, then becomes freezing state in 3 hours mutually from cooling.
In the first energy line I (1.38W), because it is quite big to be applied to the amount of energy of water, even water in phase transition temperature (being 0 ℃ under 1 atmospheric pressure) cooling, still remains on almost 0 ℃ and can be not cold excessively.
In the second energy line II (0.98W), water remains on supercooled state, and the scope of supercooling temperature is from-3 ℃ to-3.5 ℃.
In the 3rd energy line III (0.91W), water remains on supercooled state, and the scope of supercooling temperature is from-4 ℃ to-5 ℃.
In the 4th energy line IV (0.62W), water remains on supercooled state, and the scope of supercooling temperature is from-5.5 ℃ to-5.8 ℃.
At the 5th energy line V (0.36W), freezing (phase transformation) and no show supercooled state take place in water.
Fig. 9 shows the chart of the correlation between first to the 5th energy line of Fig. 8.As shown in Figure 9, at the cold air supply status, be applied to content and be the amount of energy of water and the non-cryogenic temperature of water and have proportionate relationship.That is, when the amount of the energy that is applied to content was big, non-cryogenic temperature rose, and when the amount of the energy that is applied to content hour, non-cryogenic temperature descends.Yet, if the amount of energy is too little, can cause the motion of hydrone and regulate supercooled state, reach the result of the 5th energy line V thus.
In this experiment, the amount of the energy that non-cryogenic temperature is applied when being-6 ℃ according to storage temperature (indoor temperature, internal temperature) is determined.If storage temperature changes, the amount of the energy that is applied must change.When storage temperature immobilizes, the amount of microcomputer 90 stored energys and the information of the simple correlation between the non-cryogenic temperature.Regulating or changing under the situation of storage temperature the information of the amount of stored energy and the correlation between the non-cryogenic temperature under the situation that microcomputer 90 must take in the variation to storage temperature.
Figure 10 to Figure 12 shows the chart that is used for keeping according to the loading degree relation curve of the voltage of non-freezing state and frequency.Content be contained in the plastic containers and be stored in Fig. 4 or the non-freezing refrigerator of Fig. 5 in or be contained in the housing 110 of Fig. 6 and carry out under the situation of non-freezing processing, each curve shows voltage and the frequency field that keeps non-freezing state by cold excessively.
Figure 10 carries out example to water.The water yield increases to 0.1L, 2L, 5L and 10L, when voltage and frequency are set in each zone and when keeping the motion of hydrone, have then kept non-freezing state.
Figure 11 carries out example to vegetables, and shows voltage and the frequency field that keeps non-freezing state under the condition identical with Figure 10.When the amount of vegetables is 100g, in the voltage of Figure 11 and frequency field, kept non-freezing state.
Figure 12 carries out example to meat, and shows voltage and the frequency field that keeps non-freezing state under the condition identical with Figure 10.Along with the amount of meat increases to 50g, 200g and 3kg, when voltage and frequency are set in each zone, then kept non-freezing state.
Loading changes according to the amount and the kind of content.When to the setting regions (size of voltage and frequency) of the voltage of the non-freezing state that is used to keep content when setting, with reference to figures 10 to Figure 12, frequency is in 1 to 500kHz the scope if the setting regions VFm of voltage and frequency is configured in the scope that size is in 500V to 15kV, then content can be kept at non-freezing state, no matter and how kind or amount change.In addition, frequency is in 5 to 200kHz the scope if the setting regions VFo of best voltage and frequency is configured in the scope that size is in 600V to 7kV, and then most of contents can be kept at non-freezing state, no matter and kind or amount how.
Figure 13 to Figure 16 shows the structure chart according to the layout example of the electrode of non-freezing storage device of the present invention and memory space.Non-electrode save set has non-freezing function, and it can be a non-freezing refrigerator.In the example of Figure 13 to Figure 16, owing to do not produce electric field equably in the end of electrode, therefore memory space is kept apart with the end of predetermined interval with electrode, thereby electric field can be applied to memory space relatively uniformly, so that stably keep non-freezing state.
As shown in figure 13, non-freezing storage device comprises: housing 111, and it is made by insulating materials and has a storage space S 1; Lid 121, it is used to open and close the open side of housing 111, and described lid 121 has the insertion unit 121a that inserts described storage space S 1; And electrode 51a and 51b, its insert housing 111 sidewall and towards storage space S 1.The inner bottom surface of housing 111 forms the end that is higher than electrode 51a and 51b with distance " a ", thereby the bottom of storage space S 1 can keep apart with the end of predetermined interval with electrode 51a and 51b.The insertion unit 121a of lid 121 inserts storage space S 1 with distance " a ", thereby the top of storage space S 1 can keep apart with the end of electrode 51a and 51b.The cooling structure of the non-freezing storage device of Figure 13 can form in the mode identical with the cooling structure of Fig. 4 and Fig. 5, but does not illustrate in the drawings.
As shown in figure 14, the basal surface of the end of the electrode 52a of housing 112 and 52b and storage space S 2 is formed on the same surface.Yet supporting member 140 inserts the basal surface of storage space S 2, and wherein said supporting member 140 comprises that content is placed on it shelves unit 141 and support unit 142 and have height a.Therefore, when content was stored in the storage space S 2, content was kept apart with the end of distance " a " with electrode 52a and 52b.The superstructure of storage space S 2 is identical with the superstructure of Figure 13.That is, the structure of lid 122 is identical with the structure of the lid 121 of Figure 13.The cooling structure of the non-freezing storage device of Figure 14 can form in the mode identical with the cooling structure of Fig. 4 and Fig. 5, but does not illustrate in the drawings.
As shown in figure 15, housing 113, electrode 53a and 53b and lid 123 are identical with housing 112, electrode 52a and 52b and the lid 122 of Figure 14.Yet the inner housing 150 (inside groove) with the storage space S 3 that is used for the memory contents thing inserts the storage space S 4 of housing 113 (water jacket).The external diameter of inner housing 150 (or width) reaches " 2c " less than the internal diameter (or width) of housing 113.Support unit 151 and lower surface are formed on the basal surface of inner housing 150, thereby inner housing 150 can be kept apart with electrode 53a and 53b with distance " a ".The lid 152 that is used to open and close storage space S 3 is formed on the top surface of inner housing 150.Lid 152 comprises the outstanding unit 152a that inserts inner housing 150, so that prevent shaking of lid 152.The sidepiece of inner housing 150 forms the end that is lower than electrode 53a and 53b and reaches distance " a ", thereby storage space S 3 can be kept apart with electrode 53a, 53b with distance " a ".
The support unit 151 of inner housing 150 is fixed to the inner bottom surface of housing 113.At this, the outer surface of inner housing 150 is kept apart with the distance " c " and the inner surface of housing 113.Because inner housing 150 and housing 113 are isolated from each other with predetermined interval " c ", therefore, even cold air is supplied to storage space S 4 as illustrated in fig. 4 or produces at the place, inside portion of housing 113 as illustrated in fig. 5, storage space S 3 all can be cooled off equably and can not produce rapid variations in temperature.As a result, when producing and keeping non-freezing state, the state of content is stablized.Because the top of inner housing 150 is closed by lid 152, so cold air directly is not passed in the storage space S 3.That is, content can cool off more equably by conduction.
In the drawer structure of Figure 16, the inner housing 150 of Figure 15 is not fixed to housing 113, and forms with drawer type.
With reference to Figure 16, non-freezing storage device comprises: housing 114, and it has storage space S 5, described housing 114 anterior uncovered; And drawer 160, it puts into the anterior of described housing 114 or from its taking-up.The electrode (not shown) insert housing 114 in the side surface 114a and 114b of drawer 160 sidepiece unit 160a and 160b.Be used to suck the cold air inflow pipe 36a of cold air and be used to discharge the top that is formed on housing 114 through the cold air discharge pipe 38a of the cold air of heat exchange.
Figure 17 to Figure 20 shows the concept map according to the sphering of the memory space of non-freezing storage device of the present invention.
As shown in figure 17, the end of electrode 54a to 54d corresponds respectively to the edge of storage space S 7.In this arrangement, the edge that is applied to storage space S 7 is inhomogeneous with the intensity of the electric field of inside.Especially, when the liquid such as water was stored, the edge was cooled off consumingly.Therefore, the edge of storage space S 7 and the inner temperature difference increase.If the mixing of content (water) such as convection current takes place, it is unstable that the non-freezing state of water will become.In this case, in the hydrone of content, produce nuclear, thereby can make water that cold releasing and freezing took place.
The structure of the electrode 54a to 54d of Figure 18 and layout are identical with Figure 17's.Yet all edges of storage space S 7 are made sphering and are handled.The sphering portion of storage space S 7 keeps apart with the end of predetermined interval with electrode 54a to 54d, receives electric field thus equably.As comparing, can cool off storage space S 7 equably, and stablize non-freezing state with the storage space S 7 of Figure 17.
