  (Embodiment)

  FIG. 1 is a schematic view of the refrigerator 1 according to the present embodiment as viewed from the front upper side with the door opened.

  FIG. 2 is a longitudinal sectional view of the refrigerator 1 with the door closed.

  The refrigerator 1 includes a box body 10 having therein a refrigeration chamber 11 that refrigerates objects to be refrigerated. Here, the case where the refrigerated object to be refrigerated is a food will be described as an example. However, the refrigerated object may be any substance. For example, the object to be refrigerated may be a substance having cells or the like, for example, an organ used for living body transplantation or the like. The box body 10 also has a door 12 for the refrigerator compartment 11. The box body 10 is composed of, for example, an outer wall 10a and an inner wall 10b, and a heat insulating material 10c provided between the outer wall 10a and the inner wall 10b. The door 12 may be considered as a part of the box body 10. Here, the case where one refrigerator compartment 11 is provided in the box body 10 has been described as an example. However, in the present invention, the refrigerator 1 includes one or more refrigerator compartments having different indoor temperatures or the like. 11 may be provided. In the case where a plurality of refrigerator compartments 11 are provided, each refrigerator compartment 11 is preferably provided with an independent door 12.

  The refrigerator compartment 11 is for refrigerating the accommodated foodstuff. Specifically, the refrigerator compartment 11 is a storage compartment maintained at a temperature lower than normal temperature for refrigerated storage. In addition, the refrigeration described here means storing at a temperature of room temperature or lower, and is normally maintained at a temperature of about 1 to −5 ° C. so that the food does not freeze. However, in the present embodiment, refrigeration may be considered as a concept including chilled, partial freezing, freezing, and the like. That is, the refrigerator of the present embodiment is a concept including a so-called freezer, a refrigerator-freezer, and the like. In the present embodiment, as an example, the case where the refrigerator compartment 11 is a freezer compartment will be described as an example. The foodstuff is a food that serves as a cooking material. For example, the food may be a fresh food such as vegetables, fruits, fish, or meat, or a processed food such as rice or noodles. Moreover, the food obtained as a result of cooking may be used. Pet food and the like may also be considered as food.

  A cooler 30 for cooling the inside of the refrigerator compartment 11 is provided in the box body 10. The cooler 30 forms a cooling cycle together with the compressor 31, the condenser 32, etc., and the refrigerant inserted into the cooler 30 evaporates, whereby the air in the passage 33 is cooled. The cooled air is blown into the refrigerator compartment 11 from the ventilation holes 34 by the fan 35, whereby the refrigerator compartment 11 is cooled. The refrigerant evaporated in the cooler 30 is cooled and condensed by the condenser 32, compressed again by the compressor 31, and supplied to the cooler 30. However, regarding the configuration of the refrigerator compartment 11, the mechanism for refrigeration, etc., a general refrigerator configuration or mechanism other than the above may be used.

  In the present embodiment, a case will be described in which the refrigerator 1 includes a so-called CAS freezing system as a system for freezing food in the refrigerator compartment 11, that is, the freezer compartment here. CAS freezing is a freezing method in which a frozen object is cooled to −30 to −100 ° C. and rapidly frozen while a unidirectional magnetic field is applied to the object to be frozen. The CAS freezing system is a system for realizing this refrigeration method. By performing CAS freezing, it is possible to prevent the food material from being destroyed during freezing and freeze the food material. As a result, the frozen storage with the quality maintained becomes possible. For example, for a CAS-frozen food, almost the same quality as before freezing can be obtained after thawing. The CAS freezing system is specifically a technique described in WO01 / 024647, and detailed description thereof is omitted here. In the present embodiment, the cooling cycle such as the cooler of the refrigerator compartment 11 described above and the magnetic field generator 40 disposed between the outer wall 10a and the inner wall 10b on the side of the box body 10 constitute a CAS freezing system. doing. That is, the cooling cycle of the refrigerator compartment 11 is a means for rapidly freezing the food, which is the object to be frozen in the CAS freezing system, by cooling to −30 to −100 ° C., and the magnetic field generator 40 is freezing in the CAS freezing system. A case in which a magnetic field in one direction is applied to an object will be described. The magnetic field generator 40 generates a magnetic field at the center of the refrigerator compartment 11, for example. The magnetic field generator 40 is configured by, for example, a permanent magnet of a ferrite plate, an electromagnetic coil, a combination thereof, or the like.

  As a result, the refrigerator 1 is unidirectional to the refrigerator compartment 11 that can cool the temperature around the ingredients to be frozen to −30 to −100 ° C. and the ingredients to be frozen in the refrigerator compartment 11. And a magnetic field generation unit for applying the magnetic field. For this reason, any cooling means or the like may be provided, and any magnetic field generating means may be provided. In addition, the CAS freezing system of the refrigerator 1 may be provided with a fluctuation magnetic field generating means (not shown) as in the technique described in WO01 / 024647, or generates a magnetic field having a fixed value strength. There may be provided static magnetic field generating means (not shown) for generating, and dynamic magnetic field generating means (not shown) for generating a magnetic field whose intensity fluctuates and fluctuates. Also, an electric field generating means (not shown), an air blowing means (not shown), and a sound wave generating means (not shown) for superimposing a sound wave in an audible frequency band on the cold air generated by the air blowing means are provided. Also good.

  A plurality of shelves 22 are provided in the refrigerator compartment 11 in parallel. The shelf 22 may be one stage. The shelf 22 includes a plate-like support 22a and a carbon molded plate 22b disposed on the support 22a. Here, the carbon molding plate constituting the shelf 22 is referred to as a shelf carbon molding plate 22b. The support 22a may be, for example, a plate-like member or a net-like member. The entire shelf 22 may be constituted by the shelf carbon molding plate 22b and the support 22a may be omitted. A plurality of through holes (not shown) for allowing cold air to pass therethrough may be provided in the shelf carbon molding plate 22b. The surface of the shelf carbon molding plate 22b is covered with a heat-resistant coating layer in order to prevent fine wear and defects. Note that the shelf 22 may be omitted when the food is placed directly in the refrigerator compartment.

  The shelf-shaped carbon molding plate 22b is formed as a whole as a whole by forming a crystal structure with high density and density by firing, and can be manufactured as follows. That is, about 5% by weight of a binder such as a phenol-based adhesive, pitch, or tar is added to carbon powder of carbide such as graphite or bamboo charcoal, and is hardened and pressure-molded into a predetermined lump (for example, square). And it heats in the state which oxygen deficient, and bakes at about 2000-3000 degreeC. In this state, the raw material carbon powders are bonded and crystallized (graphitization, regular carbonization). In addition, the phenol component, pitch, or tar is volatilized at about 1200 ° C. during the temperature increase. After that, the heating is stopped and the temperature is lowered, and then processed into the shape of a shelf carbon molding plate. Since the binder is volatilized in the carbon forming plate 22b for shelves, almost 100% (99.9%) is a carbon material. Thereafter, if necessary, a large number of through holes (not shown) are excavated.

  The shelf carbon molding plate 22b has a high thermal diffusivity, and when heat is applied to a part of the shelf, the heat diffuses quickly and the temperature becomes uniform. Therefore, when the food to be cooled is placed on the shelf carbon molding plate 22b, the heat of the food is quickly diffused on the shelf 222b and the cold air in the refrigerator compartment 11 is efficiently transmitted to the food. Therefore, the food is cooled rapidly. Moreover, since the far infrared rays absorbed by the shelf carbon molding plate 22b are large, the far infrared rays generated from the food are efficiently absorbed by the shelf carbon molding plate 22b, and the food is efficiently cooled.

  In addition, it is preferable that the carbon molding plate 22b for shelves is a molding plate of ultra high density charcoal. Ultra-high density charcoal has a molecular structure close to that of diamond and has the highest emissivity (absorption rate) of far-infrared rays. For example, in the manufacturing method as described above, the ultra-high-density coal is fired at a temperature of about 2800 ° C. to about 3000 ° C. for about 90 days at a pressure of about 50,000 tons / cm 2 during pressure molding. Is generated. The ultra-high-density coal used in the present application is preferably isotropic ultra-high-density carbon because of its high emissivity, but considering the low cost, pressure is applied from one direction during pressure molding. You may make it use the carbon molding board shape | molded by this.

  A carbon molding plate made of the same material as the shelf carbon molding plate 22b is disposed on the inner wall 10b of the refrigerator compartment 11. Here, this carbon molded plate is referred to as a housing carbon molded plate 20a. The size of the casing carbon molding plate 20a is appropriately determined. The carbon molding plate 20a for the housing only needs to be attached to at least a part of the inner wall 10b of the refrigerator compartment 11, and may be attached to all surfaces of the inner wall including the inner surface of the door 12, for example. good. Here, as an example, it is assumed that the casing carbon molding plate 20a is attached to all the regions above the ceiling in the refrigerator compartment 11 and the position of the shelf 22 on the lowest side wall. In addition, the inner wall 10b of the refrigerator compartment 11 is a material which has heat resistance, such as a metal material (for example, stainless steel) or a resin material, for example. Since the far infrared rays absorbed by the housing carbon molding plate 20a are large, far infrared rays generated from the food material are efficiently absorbed by the housing carbon molding plate 20a, and the food material is efficiently cooled. Note that the casing carbon molding plate 20a is attached to the entire inner wall of the drying chamber 11 including the inner surface of the door 13 including the inner surface of the drying chamber 11, so that a large amount of far-infrared rays is added to the food to be dried. It is preferable in that it can be efficiently dried at high speed.

  Briefly describing the operation of the refrigerator 1 of the present embodiment, when the power is turned on, the refrigerant compressed by the compressor 31 is sent to the cooler 30 and the refrigerant inserted into the cooler 30 evaporates. Thus, the air in the passage 33 is cooled. The cooled air is blown into the refrigerator compartment 11 from the ventilation holes 34 by the fan 35, whereby the refrigerator compartment 11 is cooled. The refrigerant evaporated in the cooler 30 is cooled and condensed by the condenser 32, compressed again by the compressor 31, and supplied to the cooler 30. Further, when freezing the food material, the cooling temperature is set to −30 to −100 ° C., and the magnetic field generation unit 40 generates a magnetic field for the refrigerator compartment 11. Thereby, a foodstuff will be CAS freezing.

  According to the present embodiment, the shelf carbon molding plate 22b efficiently dissipates and dissipates the heat of the food disposed on the shelf, and the shelf carbon molding plate 22b efficiently absorbs far infrared rays. Efficient and rapid cooling of ingredients. Further, the casing carbon molding plate 20a in the refrigerator compartment 11 and the shelf carbon molding plate 22b of the upper shelf 22 also absorb the far infrared rays to help cool the food. Thus, as a result of the food being efficiently cooled in a short time, there is little destruction of the tissue due to cooling, and it is possible to reduce the taste and the outflow of nutrients. Thereby, the quality deterioration by cooling can be prevented and the foodstuff of a favorable state can be provided.

  In addition, because the shelf carbon molding plate 22b and the like are used, even if the food is placed directly on the shelf carbon molding plate 22b, it is difficult for the food to stick to the shelf carbon molding plate 22b during refrigeration. Handling can be very easy.

  In the present embodiment, the case where the object to be refrigerated is a food is described as an example. However, as described above, the refrigerator of the present invention can refrigerate objects to be refrigerated other than food. . In particular, in the refrigerator of the present invention, since it is possible to prevent deterioration of quality of tissues and the like, it is particularly useful for refrigeration countermeasures having cells and tissues, such as foodstuffs, plants, and cell samples. Is suitable.

  Note that the refrigerator of this embodiment may be a portable refrigerator that can be carried by downsizing the size and the like. In this case, the cooler 30 or the like may be driven by a battery or the like (not shown) so that the food can be refrigerated, or a configuration that requires power for cooling the battery or the cooler 30 or the like is not used. Further, refrigeration may be performed by disposing a cold storage medium such as dry ice or a cold insulating agent (not shown) in the refrigeration chamber. Alternatively, in addition to the configuration for cooling the battery, the cooler 30, and the like, refrigeration may be performed by disposing dry ice, a refrigerant, or the like (not shown) in the refrigerator compartment. Such a portable refrigerator is useful as a refrigerator for refrigerated and transported organs necessary for, for example, living-body transplantation. In particular, by using the refrigerator of the present application, rapid refrigeration is possible, organ deterioration is prevented, and organs can be carried while maintaining freshness. Such a portable refrigerator is a concept including a so-called refrigeration box.

  In the present embodiment, the case where the casing carbon molding plate 20a and the shelf carbon molding plate 22b are provided has been described. However, in the present invention, the casing carbon molding plate 20a or the shelf carbon molding plate is formed. Either one of the plates 22b may be omitted.

  Moreover, in the said embodiment, although the case where the carbon molding board 22b for shelves and the carbon molding board 20a for housing | casings were provided was demonstrated, in this invention, a carbon molding board is a refrigerator compartment in aspects other than these. 11 may be arranged, and even in such a case, the same effect as described above is obtained.

  The present invention is not limited to the above-described embodiments, and various modifications are possible, and it goes without saying that these are also included in the scope of the present invention.

  As described above, the refrigerator according to the present invention is suitable as a device for refrigerating a refrigerated object, and is particularly useful as a refrigerator or the like for storing a refrigerated object while preventing deterioration in quality.
