Description

  The present invention relates to a refrigerator capable of storing a beverage in a beverage container in a supercooled state.

  Conventionally, many commercially available PET bottles, cans, glass, beverages in paper containers (soft drinks, alcohols) are cooled and stored in the temperature range of -20 ° C to 0 ° C, so that even below the freezing point A supercooling phenomenon that indicates the state of the liquid occurs, and when energy such as vibration and impact is applied to the liquid in the supercooled state, it is used as a trigger to instantly convert it into a sherbet. It may change, and storing the beverage in the beverage container in a supercooled state has gained popularity.

  This supercooling phenomenon is a well-known physical phenomenon for a long time, and the thermal motion of water molecules decreases as the temperature decreases due to cooling. As the temperature decreases, the difficulty of solidification increases and a supercooled state that is a liquid is generated even at a temperature below the freezing point. However, below the freezing point, the solid is stable in a liquid-unstable state (defined as a thermodynamic metastable state). It is characteristic that it changes and solidifies.

And conventionally, as a refrigerator, there exists a thing which arrange | positions a supercooling container in a supercooling chamber and preserve | saves the beverage container in this supercooling container in a supercooled state by indirect cooling (patent 3903605 gazette: (See Patent Document 1 and Japanese Patent No. 393066: Patent Document 2). That is, the beverage container in the supercooling container is indirectly cooled by the cold air flowing outside the supercooling container. And the temperature in the said supercooling container is detected with the temperature sensor.

  The holding member 2 is provided with a thermistor 13 as a temperature sensor. The thermistor 13 is provided individually corresponding to the beverage container 3 and detects the temperature of the beverage container 3 by directly contacting the beverage container 3.

  That is, the holding member 2 is formed so as to hold the plurality of beverage containers 3, and a plurality of thermistors 13 that individually measure the plurality of beverage containers 3 are arranged.

  All the thermistors 13 are located in the same space opened in the multi-chamber 50b while the cool air directly circulates. And the said drink container 3 which contacted each said thermistor 13 in the said multi chamber 50b is directly sprayed with cold air, and the drink in the said drink container 3 is preserve | saved in a supercooled state.

  Here, “all thermistors 13 are located in the same space opened in the multi-chamber 50b while the cold air circulates directly” means that each thermistor 13 is completely partitioned one by one. In addition, the beverage container 3 that is in contact with each thermistor 13 is not cooled by indirect cooling.

  Specifically, the holding member 2 is a beverage holder in which three beverage containers 3 can be stored. The holding member 2 includes a top plate 7 attached to the refrigerator main body 50 via the cushion material 12, a support portion 8 that supports the beverage container 3 in a sideways state, the top plate 7, and the support portion 8.

  The support portion 8 includes a plurality of concave groove portions 83 into which the beverage containers 3 are fitted, and a convex portion 84 disposed between the adjacent concave groove portions 83. In this embodiment, there are three concave grooves 83 and two convex portions 84.

  A stopper plate 11 that contacts the bottom surface of the beverage container 3 is provided at one end of the support 8. The stopper plate 11 is disposed so as to close one end of each concave groove 83. The one end portion of the support portion 8 is located on the back side of the multi-chamber 50b, and ensures the convenience that the beverage container 3 can be easily taken in and out from the front surface of the multi-chamber 50b.

  The concave groove 83 and the stopper plate 11 form a storage compartment for storing the beverage container 3. There are three storage compartments.

  Each thermistor 13 is arranged at one end of each concave groove 83. That is, the thermistor 13 is disposed at one end portion of the support portion 8 that contacts the bottom of the beverage container 3.

  Thus, the beverage container 3 is inserted into the storage compartment, the beverage container 3 is fixed and held at a position where it hits the stopper plate 11, and the thermistor 13 is provided at a position where it hits the bottom of the beverage container 3. Therefore, the temperature of the beverage container 3 is measured in real time by contact heat conduction.

  The convex portion 84 is a contact prevention member and prevents the beverage containers 3 arranged in the concave groove portion 83 (the storage section) from contacting each other. The convex portion 84 includes an upper portion 85 having a flat upper surface and a wall portion 86 provided at the center of the upper surface of the upper portion 85 in the width direction.

  Thus, since the storage section is stored so as to have a certain interval, the adjacent beverage containers 3 are not affected by each other, and a passage through which cooling air passes is also ensured.

  The support portion 8 is disposed so as to be inclined so that the one end portion of the support portion 8 is positioned below the other end portion. That is, as shown in FIG. 4, due to the weight of the beverage container 3, the rear end portion of the support portion 8 is lowered 5 ° downward from the horizontal state by the long hole 91 provided at the lower end of the rear suspension plate 9b. Decrease. Therefore, destabilization of the beverage container 3 is prevented, the contact with the thermistor 13 is ensured, and the beverage container 3 is easily taken in and out.

  As shown in the plan view of FIG. 5 and the AA sectional view of FIG. 5 of FIG. 6, the support portion 8 is capable of moving forward and backward relative to the first support body 81 and the first support body 81. And a second support 82 attached thereto.

  The first support 81 is located on the opening side (the door 52 side) of the multi chamber 50b, and the second support 82 is located on the back side of the multi chamber 50b.

  The first support body 81 and the second support body 82 are connected by a tension spring 14, and the first support body 81 and the second support body 82 are moved toward each other by the tension spring 14. To be pulled.

  The second support 82 slides in a direction parallel to the first support 81. In other words, the second support 82 can advance and retreat in the axial direction (height direction) of the beverage container 3 lying on the support 8.

  The thermistor 13 is disposed on the second support 82 and moves forward and backward relative to the first support 81 together with the second support 82.

  The thermistor 13 is attached to a heat insulator 130, and the heat insulator 130 is fitted in a hole provided in the second support 82. The lower end surface of the heat insulator 130 is supported by the tension spring 14. When the beverage container 3 is placed, the heat insulator 130 moves downward while being supported by the tension spring 14 until the beverage container 3 comes into contact with the groove 83.

  Then, as shown in the operation explanatory diagram of FIG. 7, when the beverage container 3 is a tall container such as a wine bottle having a height size of about 30 cm, the beverage container 3 is placed on the support portion 8. Is inserted into the stopper plate 11, but the tension spring 14 is extended by a force pushing further in the back direction, and the second support 82 slides in the back direction together with the thermistor 13, and the tall beverage container 3 Is surely supported.

  In FIG. 7, the second support 82 on the left side of the paper surface shows a state where it is not slid in the back direction, and the second support body 82 in the center of the paper surface shows a state where it is slid moderately in the back direction, The second support 82 on the right side of the drawing shows a state of sliding to the farthest side.

  As shown in the side view of FIG. 8, the holding member 2 is configured to be foldable. That is, when the beverage container 3 is not to be stored, the handle 10 provided at the front portion of the support portion 8 is held and pushed to the rear rear side, whereby the front suspension connected by the link mechanism is used. The lower plate 9a and the rear suspension plate 9b are lifted upward, and the holding member 2 is folded.

  By providing a projection at the tip of the stopper plate 11 and hooking on the top plate 7 so as to be a so-called snap fit structure, the folded state is maintained, and when used, if the handle 10 is pulled with an appropriate force, The holding member 2 can be switched to the unfolded state. By adopting such a structure, when the holding member 2 is not stored, the inside of the multi-chamber 50b can be widely used at an arbitrary temperature, and the usability of the refrigerator is not impaired.

  In addition, it is possible to determine whether or not the beverage container 3 is present by providing a switch or the like that can be used or not used in the expanded use state and the folded storage state, or a switch is provided near the thermistor 13. By providing the function, the presence or absence of the beverage container 3 can be determined individually.

  As shown in FIG. 1, the notification lamp 4 notifies that the beverage in the beverage container 3 has been achieved in a supercooled state based on the temperature of the beverage container 3 detected by the thermistor 13. .

  The temperature setting unit 6 includes a control unit, and the control unit stores the beverage in the beverage container 3 in a supercooled state based on the temperature of the beverage container 3 detected by the thermistor 13. When it is determined that there is no change, the temperature in the multi-chamber 50b is changed from the first temperature at which the beverage in the beverage container 3 is stored in a supercooled state to the liquid in the beverage container 3 in a liquid state. Change to the second temperature to be stored.

  Here, although the absolute value of the first temperature varies depending on the beverage type, it is a temperature level below the freezing point (for example, −4 ° C. to −12 ° C.), and the second temperature is frozen even if left standing. The temperature level is above the freezing point where it does not progress (eg, 3 ° C.).

  In order to change the temperature in the multi-chamber 50b from the first temperature to the second temperature, for example, a damper for controlling the flow of cold air into the multi-chamber 50b, or the temperature in the multi-chamber 50b A heater that raises the temperature is used.

  Next, an example of actual use and control of the refrigerator configured as described above will be described in detail.

  The multi-chamber 50 b is set to a subcooling temperature for −6 ° C. soft drink by the temperature setting unit 6, and the beverage container 3 is put into the holding member 2. The inside of the multi-chamber 50b is controlled to about −6 ° C. ± 2 ° C. by the cold air circulation of the refrigerator, and the beverage container 3 is cooled.

  Since the thermistor 13 for detecting the temperature of the beverage is provided in the holding member 2, the temperature of the beverage container 3 is detected and the temperature can be grasped in real time.

  If the temperature of the beverage container 3 is detected to be −6 ° C. ± 2 ° C., it is in a state of supercooling, so the user can turn on the notification lamp 4 and simultaneously drive the notification sound and the like. It is possible to know that the supercooling can be reliably performed. In addition, the freezing point of soft drink water exists in the category of about 0 degreeC--2 degreeC.

  On the other hand, the multi-chamber 50 b is set to the −12 ° C. alcohol beverage supercooling temperature by the temperature setting unit 6, and the beverage container 3 is put into the holding member 2. The inside of the multi-chamber 50b is controlled to about −12 ° C. ± 2 ° C. by the cold air circulation of the refrigerator, and the beverage container 3 is cooled.

  Since the thermistor 13 for detecting the temperature of the beverage is provided in the holding member 2, the temperature of the beverage container 3 is detected and the temperature can be grasped in real time.

  If the temperature of the beverage container 3 is detected to be −12 ° C. ± 2 ° C., it is in a state where supercooling is occurring. Therefore, the user turns on the notification lamp 4 and simultaneously drives the notification sound or the like. It is possible to know that the supercooling can be surely performed. The freezing point with an alcohol content of less than 16 degrees is in the range of about -7 ° C to -10 ° C.

  Note that the same number of notification lamps 4 may be provided with respect to the quantity of beverage containers 3 to be stored, and it is detected that all three beverage containers 3 in a group unit are −6 ° C. ± 2 ° C. At this stage, the notification lamp 4 may be turned on.

  As mentioned above, although the example of the temperature setting in two types of beverages was shown, since there are some types of alcoholic beverages having a freezing point of −7 ° C. or higher and those below −10 ° C., the set temperature can be appropriately selected and switched. It is preferable to configure.

  By controlling as described above, it is possible to reliably notify the user that the supercooled state has been reached even if there is a difference in the beverage container type, content, initial temperature, and charging time for each beverage. It becomes possible to enjoy a sherbet beverage under certain conditions.

  Next, the freeze prevention control of the beverage container 3 will be described.

  FIG. 9 is a diagram schematically showing a temperature change pattern of soft drinks (temperature set value−6 ° C.) stored in advance in the storage device of the control unit, and is a cooling curve indicated by reference numeral 20 by a one-dot chain line. Is a curve that shows a case of freezing in rare cases, or a case where a soft drink is erroneously added to a supercooling temperature setting (−12 ° C.) for alcoholic beverages. It is a pattern that is maintained.

  The cooling curve indicated by reference numeral 21 with a two-dot chain line maintained -6 ° C, but the temperature suddenly increased to 0 ° C, and then maintained at 0 ° C, and release from the supercooled state occurred. This is a pattern of freezing.

  The cooling curve indicated by the solid line 22 is a pattern in which −6 ° C. is maintained and the supercooled state is maintained.

  Accordingly, when the thermistor 13 detects a pattern other than the curve 22, if it is left unattended, it will be completely frozen, so the second storage in which the freezing does not proceed even if it is left from the first storage temperature range that is the set value. It automatically shifts to a temperature zone (for example, 3 ° C.) and turns on the specific alarm lamp 5 to notify the abnormality.

  The patterns to be memorized are patterns of absolute values of temperature and time changes, and the pattern examples are the following five patterns a) to e).

In the case of soft drinks (non-alcohol), -6 ° C is set as the first storage temperature zone,
a) As a pattern that freezes in rare cases, a pattern that continues for about 30 minutes to 1 hour or more with no temperature drop from about 0 ° C. with respect to the elapsed time b) A pattern that is released by being given some energy from a supercooled state As a pattern, the temperature rises rapidly within a few minutes from the state of maintaining −6 ° C. on average with respect to the elapsed time, and the pattern in which the vicinity of 0 ° C. is continued for about 30 minutes to 1 hour or more is the first -12 ° C was set as the storage temperature zone for
c) As a pattern that freezes in rare cases, a pattern that continues for about 30 minutes to 1 hour or more with no temperature drop from about -7 ° C with respect to the elapsed time d) Some energy is applied from the supercooled state and released. As a pattern, the temperature rapidly rises within a few minutes from the state of maintaining -12 ° C on average with respect to the elapsed time, and continues around -7 ° C for about 30 minutes to 1 hour or more with respect to the set temperature If there is an error, -12 ° C is set as the first storage temperature zone.
e) A pattern that continues for about 30 minutes to 1 hour or more with no temperature drop from about 0 ° C. with respect to the elapsed time. However, since the first storage temperature zone set value changes depending on the alcoholic beverage type, the freezing point is −7 ° C. Since the absolute value also changes accordingly, it should be adjusted as appropriate.

  A curve 20a shown in FIG. 10 is a cooling curve of a beverage in which a multi-chamber 50b of an actual refrigerator is set to −6 ° C., and a soft drink system “tea” containing a commercially available 500 ml PET bottle is cooled and stored from an initial temperature of 5 ° C. This is an example in which a temperature drop occurs after maintaining around 0 ° C. for about 6 hours, and complete freezing occurs in about 9 hours. As can be seen from the temperature curve, the actual refrigerator temperature control is basically the ON / OFF control of the compressor, so the temperature is maintained at around 0 ° C while the temperature fluctuates. When about 1.5 ° C. is set as the temperature fluctuation range and this state is maintained for about 30 minutes to 1 hour, it can be determined that the freezing is proceeding.

  The curve 21a shown in FIG. 11 shows the beverage when the multi-chamber 50b of the actual refrigerator is set to −6 ° C., and the soft drink system “tea” in a commercially available 500 ml PET bottle is stored for 24 hours from the initial temperature of 5 ° C. It is a cooling curve and immediately rises to 0 ° C. immediately before the 21st hour from the state maintained at around −5 ° C. to release the supercooling, and then maintains 0 ° C. with the heat of solidification, leading to freezing. It is an example. Similarly to the above, a temperature fluctuation range of about −6 ° C. ± 1.5 ° C. is detected, a temperature change rising to 0 ° C. in about a few seconds is detected, and then the vicinity of 0 ° C. is maintained for about 30 minutes to 1 hour. If it is, it can be determined that the supercooling has been released.

  The curve 22a shown in FIG. 12 shows the beverage when the multi-chamber 50b of the actual refrigerator is set to −6 ° C., and the soft drink system “tea” in a commercially available 500 ml PET bottle is stored for 12 hours from the initial temperature of 5 ° C.
