Description

  The present invention relates to a freezer that freezes or cools an object to be cooled by being deformed according to the shape of the object to be cooled.

Heating tools and equipment have been widely used since ancient times because natural resources can be used as they are, but refrigeration and cooling tools and equipment are limited to use artificial materials and equipment. Only limited-use products have become widespread. Despite the many potential needs for freezing or cooling foods indoors and outdoors, and for easily cooling the human body and things, commercialization of useful and practical tools and equipment has been made. Not.

For example, the fact is that there is no custom of freezing cooking while enjoying with your favorite ingredients, and enjoying a variety of handmade frozen dishes that are not mass-produced products. Ice cream and popsicles are sometimes made in science classes and special dishes at home, but very rarely. As a cooking method, ice, water, salt, and the like are put in a container, and a container such as a bowl is placed in the ice water to freeze the food.

This cooking has been avoided because the ice, water, and salt must be thrown away before and after cooking and every time it is cooked. On the other hand, various toys that make ice cream by the above cooking method for children and cups that solidify in a refrigerator with water and air in the cavity are also commercialized, but there is an air layer in the cavity of the vessel It has poor refrigeration capacity and uses are limited.

In addition, there are many types of coolers that use water and ice and water and polymer absorbents as coolers that cool the human body due to fever and bruises. The current product has a problem such as poor cooling capacity. On the other hand, there is a problem that even if trying to utilize a cold insulation material for food that uses latent heat with cooling ability, the cold insulation material becomes hard when it solidifies, so it feels bad and the contact area with the object to be cooled is small and it is difficult to use. .

A cold insulator (see, for example, Patent Document 1) in which water or a cold insulating material that freezes with water as a main component and a lubricant is encapsulated has been devised so as to deform in accordance with the human body. When the lubricant is completely filled between the small enclosures, the cooling capacity is lowered, so that a space is formed between the small enclosures, which is disadvantageous for heat conduction. In addition, when a large amount of a small enclosure and a lubricant are added, there is a disadvantage that deformation is difficult when a load is applied, and it is difficult to say that the body is freely deformed along the shape of the human body.

Despite the potential needs for refrigeration and cooling equipment and equipment in all fields, as well as heating equipment and equipment, there are no useful and practical freezing tools that can be noticed. Even if they are commercialized, they are not easy to use, some are useless to throw away, the cooling performance is poor, the applications are limited, and they cannot be diverted to others, so they lack a global perspective from a user perspective.

For example, there is no practical cold insulator that has a high freezing capacity and can be flexibly deformed according to the object to be cooled, or it can be frozen only in a form that is unilaterally provided by food manufacturers regardless of individual preference or amount to eat. There are problems such as being unable to enjoy food. With the present invention as a trigger, the potential market becomes clear, and various instruments and equipment for freezing and cooling are expected to spread.
JP 2001-346822 A

  The present invention has been made to solve the above-mentioned problems. The purpose of the present invention is to make a desired amount of original frozen dishes using dishes and cooking utensils, or to promote foaming of cream when making cakes. In applications such as cooling foods that have been cooked or cooked, cooling human bodies or other objects to be cooled, etc., it is deformed according to the shape of the object to be cooled, such as cooking utensils and human bodies, and has excellent cooling performance By providing an exemplary freezer, it contributes to flowering of potential needs in the market and the creation of various practical freezers triggered by the present invention.

After freezing or cooling processing by bringing a to-be-cooled object such as a cooking utensil containing ingredients or tableware or ingredients into contact with a freezer stored in a refrigerator freezer, etc., simply returning the freezer to the refrigerator, etc. Convenient refrigeration with excellent ease of use and excellent cooling performance such as the freedom to limit the objects to be cooled, such as instruments, objects and human bodies, and the time to cool in a refrigerator etc. It is an object to provide tools.

In order to achieve the above object, a freezer according to claim 1 of the present invention is characterized in that at least a portion in contact with an object to be cooled is not a rigid body but formed of a soft material that can be deformed and a freezing point temperature is different in the body. It comprises two types of latent heat storage materials and a partition member that separates the two types of latent heat storage materials in the main body.

The latent heat regenerator material solidified under an environment below the freezing point temperature can take a lot of heat from the surroundings by the heat of fusion accompanying the phase change when returning to the liquid state. Further, when sensible heat due to a temperature difference from the surroundings or a sodium chloride aqueous solution is a latent heat storage material, heat can be taken away from the surroundings by absorbing heat when sodium chloride is dissolved again in water.

The freezer of the present invention has two types of latent heat regenerators having different freezing point temperatures in the main body of the freezer, and the two types of latent heat regenerators are separated by a partition member. When freezing or cooling the object to be cooled using this freezer, one of the two types of latent heat storage materials is used in a solidified state and the other is used in a liquid or semi-solid state with a lower freezing point temperature than the former. The

The latent heat storage material in the solidified state plays the role of cold storage to increase the cooling capacity, the latent heat storage material in the liquid or semi-solid state plays the role of cold storage and the role that the freezer can be fluidly deformed according to the shape of the object to be cooled. ing. The main body of the freezer is made of a material that can be deformed at least in contact with the object to be cooled, and the deformed part of the main body depends on the shape of the object to be cooled, such as cooking utensils, tableware, bottles, cans and human bodies The object to be cooled can be frozen and cooled by freely deforming and closely contacting.

The material of the container is plastic, rubber, metal, glass, ceramics, special paper, plastic film, metal film, etc., with a cold resistance of at least −20 ° C., and a material that can withstand repeated cooling between the freezer and room temperature It is. However, at least a part of the vessel body is formed of a soft material that can be deformed according to the shape of the object to be cooled. On the other hand, in the specification of a freezer that can also be used for cooling hot water, the material satisfies the condition that the heat-resistant temperature is 100 ° C. or higher.

There are two types of latent heat storage materials in the main body, and at least part of the main body and the partition member are made of a soft material that can be deformed even when the latent heat storage material solidifies by about 1.1 times. Therefore, the refrigerating capacity is higher than that of a type in which an air layer is present in a conventional instrument. Moreover, since it cools using two types of latent-heat cool storage materials, the performance of a refrigerator etc. can be utilized to the maximum.

The specifications of home refrigerators are usually −18 ° C. or lower, but when the actual temperature of the freezer compartment of some companies was examined, it was about −15 ° C. to about −30 ° C., and the performance varied. The juice begins to freeze at 0 ° C and sherbet is formed. Ice cream becomes creamy at less than -5 ° C. For food, it is desirable that the two types of latent heat regenerators solidify at -5 ° C or lower.

When the latent heat regenerator material used in the solidified state of the freezer is, for example, a sodium chloride aqueous solution, the freezing point temperature decreases in proportion to the concentration of sodium chloride, and is about -11 ° C at 15% by weight, and about -21 ° C at 23% by weight or more. Can be lowered. Since the refrigerator for home use usually falls to about -21 ° C., it is desirable that the concentration of sodium chloride is high in order to increase the freezing capacity of the freezer. On the other hand, the cold storage material for latent heat regenerators on the market is designed to solidify even in refrigerators where the freezer temperature does not drop, and the fact is that the performance of refrigerators is not fully used.

When the latent heat regenerator material used in the liquid or semi-solid state of the freezer is, for example, a calcium chloride aqueous solution, the freezing point temperature is lowered to about −55 ° C. in proportion to the concentration of calcium chloride. Therefore, a desired latent heat regenerator that remains in a liquid or semi-solid state even when the temperature is lowered to the freezer temperature of the refrigerator can be produced by adjusting the concentration or mixing other salts.

As a latent heat regenerator used in a liquid with a lower freezing point temperature or in a semi-solid state, it is cheap and safe by adding sodium chloride (salt), powdered gelatin or polymer absorbent to a calcium chloride aqueous solution of food salt. An aqueous solution or the like is conceivable. For example, it is prepared so as to be in a liquid or semi-solid state even at a temperature of about −30 ° C. in the freezer of a high-performance refrigerator.

The freezer according to claim 2 of the present invention is such that a latent heat regenerator material having a higher freezing point temperature among two types of latent heat regenerator materials is sealed in at least one container of a partition member and injected and held in the container body. It is characterized by being separated from the latent heat storage material having the lower freezing point temperature. Around a plurality of containers such as a spherical shape or a prismatic shape containing a latent heat storage material with a higher freezing point temperature in a solidified state, a latent heat storage material with a lower freezing point temperature in a liquid or semi-solid state is filled. Since the inside of the vessel body can freely flow, the vessel body can be deformed according to the shape of the object to be cooled.

In order to improve the cold storage performance, increase the amount of latent heat regenerator material with higher freezing point temperature that solidifies (phase change) in the container body, and increase the amount of latent heat regenerator material with lower freezing point temperature in liquid or semi-solid state. Is preferably as small as possible. For example, the space occupied by the latent heat regenerator material having the lower freezing point temperature can be reduced by mixing the containers of the partition members.

In the freezer compartment, first, the latent heat regenerator material having the lower freezing point temperature charged on the outer peripheral side in the container body is deprived of heat and the temperature is lowered. When the lowered temperature becomes lower than the freezing point temperature of the latent heat storage material having the higher freezing point temperature, the latent heat storage material having the higher freezing point temperature in the container is solidified.

The latent heat storage material with the lower freezing point temperature solidifies and melts faster than the latent heat storage material with the higher freezing point temperature, so that the latent heat storage material with the lower freezing point temperature is completely solidified in the freezer compartment. Even if the product specification is enhanced, it is clear that the container body can be deformed according to the shape of the object to be cooled if it becomes liquid or semi-solidified when the freezer is used, and the effect of the present invention can be obtained.

The refrigerator according to claim 3 of the present invention is characterized in that the latent heat regenerator holding part in the main body is provided with a heat conductive material having a high thermal conductivity, so that the heat transfer in the main body is accelerated and the latent heat regenerator is stored. The phase change of the material is also promoted. Considering that it has conventionally been necessary to store the latent heat storage material in the freezer compartment for a long time, the merit of providing the heat conduction material in the latent heat storage material holding part is great. In addition, there is an effect that the object to be cooled is also quickly reduced in heat.

A candidate for the heat conducting material is a metal material with good heat conductivity such as stainless steel, aluminum, or copper. Considering the environment such as salt water, depending on the material, an ultra-thin coating for salt water is required on the metal surface. As the shape of the heat conductive material, a coiled shape of a wire, a fin shape obtained by bending a sheet metal, or the like can be considered. Further, the heat conducting material may be formed of one long object or may be a form in which a plurality of short objects are dispersed.

According to a fourth aspect of the present invention, there is provided a freezer comprising a heat insulator that covers the outer peripheral portion of the main body. Refrigeration equipment with better cooling performance that is stored at low temperatures requires measures such as prevention of heat loss due to a large temperature difference from the atmosphere, water droplet adhesion, and prevention of frostbite when holding the freezing equipment for a long time, The practical effect by providing the heat insulating body which covers the outer peripheral part of a vessel main body is large.

The heat insulator is preferably one that covers the outer peripheral portion of the vessel body except for the contact portion with the object to be cooled, but even if it is a heat insulator that covers the entire outer peripheral portion, it can be covered when it is used by turning part of the heat insulator. Of course, any structure that exposes the contact portion with the cooling body is acceptable. Moreover, if the handle part which can be grasped by hand is provided in a part of the heat insulator, the freezer can be freely manipulated with the handle part. Moreover, if there is a handle part, a freezer can be held without cooling the hand.

The freezer according to claim 5 of the present invention is characterized in that the heat insulator and the container main body are detachable, so that if the heat insulator that prevents heat loss in the room is put in the freezer compartment, the freezer can be quickly removed. Can be stored cold. In addition, since the insulation body can also serve as the body of the container, such as the reinforcement of the container body and stability when placed on a table, the presence of the insulation body can further reduce the thickness of the container body, etc. The latent heat storage material will solidify faster.

Moreover, when the effective utilization of the limited space of a freezer compartment is considered, the merit which can remove an insulator from a freezer and can make it small is large. When used outdoors, the cooling performance can be further enhanced by inserting dry ice or the like between the heat insulator and the vessel body.

According to a sixth aspect of the present invention, there is provided a freezer according to the present invention, characterized in that a unit body and a heat insulator are detachable, and a recessed portion for freezing or cooling the object to be cooled is provided integrally with the heat insulator of the fifth aspect. As a result, the object to be cooled such as food introduced into the recess can be frozen by simply setting the main body taken out of the freezer compartment or the like in the unit of the insulator with the recess.

It is possible to save the trouble of separately preparing the cooking utensils and the trouble of stably fixing the cooking utensils to the freezer. In addition, since the main body of the present invention can be freely deformed without being hardened like conventional cold insulation materials, it becomes possible to make the concave portion formed integrally with the heat insulator uniformly contact with the main body of the food, and the food material put into the concave portion The object to be cooled such as can be efficiently refrigerated.

The refrigeration tool according to claim 7 of the present invention is characterized in that it has at least one concave portion to be frozen or cooled by putting the object to be cooled in the main body. If the container is inserted, it can be frozen or cooled, such as making ice lolly or ice outside the refrigerator. The concave part of the vessel body is made of a deformable soft material and makes uniform contact with the inserted container. If a keyway is provided in the recess, the container can be easily inserted and removed due to air escape or deformation of the recess when the container is inserted or removed.

By providing a plurality of recesses, it is possible to meet the potential needs to enjoy various frozen cooking using various ingredients at once. Even when the same food is used, if there are a plurality of recesses, the container can be subdivided and the time for freezing cooking is further shortened. Cooking can be made more enjoyable if the shape of the recess as viewed from above is made into a different shape such as a circle, square or heart shape.

The freezer according to claim 8 of the present invention has a structure in which the body to be cooled sandwiches the object to be cooled from both sides, and the object to be cooled is held in the body to be frozen or cooled. Since both sides of the vessel main body that contacts the cooled object to be deformed are deformed, there is a degree of freedom in the shape of the cooled object that can be charged by promoting the refrigeration process by increasing the contact area, keeping cold by blocking the cooled object from the outside air Such effects can be expected.

In addition, if a heat insulator is provided on the outer periphery of the main body, it is convenient to carry the hand without cooling. It is practical and useful to obtain the freezer of the present invention and favorite foods (beverages, frozen foods, etc.) from the freezer compartment of homes or shops and enjoy freezing or cooling cooking outdoors.

The freezer according to claim 9 of the present invention has a double-structured bag-like outer peripheral portion of the vessel body, and stores two types of latent heat regenerators in the double-structured cavity, It is characterized in that the object to be cooled is held in a removable manner. Since the bag-like portion of the vessel body can be deformed, it is possible to promote the freezing or cooling process of the object to be cooled that has been introduced from the outside.

In addition, it can be expected that the object to be cooled can be kept cool by shutting off from the outside air, the shape of the object to be cooled can be freely set, and the heat can be carried without being cooled by the heat insulator on the outer periphery of the vessel body.
If there is no heat insulator on a part of the outer peripheral part of the vessel main body or if a part of the heat insulator on the outer peripheral part can be peeled off, the object to be cooled can be frozen or cooled at the outer peripheral part without the heat insulator.

As described in detail above, the freezing tool with high freezing performance that can be deformed according to the shape of the object to be cooled according to the present invention makes it easy to make your own frozen or cooled dishes with your favorite ingredients using familiar cooking tools etc. You can. It can also be diverted to cooling applications such as slowly cooling hot milk and other dishes to human skin, and can be used as a valuable freezer like other cookers.

Convenience such as simply putting the cooking utensils or cans or bottles containing ingredients against the freezing utensils taken out of the refrigerator, refrigeration treatment, and then returning the freezing utensils to the refrigerator, and familiar cooking utensils and ingredients It is possible to provide an easy-to-use freezer that has excellent freezer performance such as ease of freezing using a refrigerator, a short cooling time in a refrigerator, and the ability to freeze a desired amount of an object to be cooled at room temperature. In addition, the appearance of new frozen dishes and new ways to enjoy food can be expected.

In addition, with the configuration of the present invention described in detail, it can be expected to be used in-house as a simple freezer or cooler that can be moved by a company or in new businesses. It is expected that the use of the freezing tool of the present invention, which is a latent heat regenerator material and has high freezing performance and deformable characteristics, is also used in sports where ice has been used as an emergency measure such as conventional bruises.

Despite the potential needs for various refrigeration / cooling or cooling processes for various objects to be cooled in homes, companies, sports, etc., the lack of refrigeration performance due to the presence of air in the latent heat storage layer and the use of ice, etc. Considering the fact that there is no truly practical instrument that can be cooled by freezing due to problems such as solidifying when it solidifies, the role of the freezer of the present invention is significant.

Embodiments for carrying out the present invention will be described in Embodiments 1 to 8.

Reference numeral 1 denotes a freezer main body, and the entire main body 1 or at least the deformed portion 2 of the main body that contacts the object to be cooled is formed of a soft material such as silicon rubber, metal foil, or plastic film. The cavity of the vessel body 1 is filled with a latent heat storage material 4 and a plurality of spherical partition member containers 3 filled with a latent heat storage material 5 having a higher freezing point temperature than the latent heat storage material 4.

Since the latent heat regenerator material 4 is cooled in the freezer compartment or the like and falls below the freezing point temperature of the latent heat regenerator material 5, the latent heat regenerator material 5 with the higher freezing point temperature can be solidified. The latent heat regenerator material 4 is fluid or semi-solidified in a specification that does not normally solidify in the freezer compartment, and is fluid. Depending on the shape of the object to be cooled such as cooking utensils, tableware, bottles, cans and human bodies, The deformable portion 2 can be freely deformed and brought into close contact, and the object to be cooled can be frozen or cooled.

Although the latent heat regenerator material 4 may be completely solidified in a high-performance refrigerator or the like, when the refrigerator is used, the latent heat regenerator material 5 is solidified so that the latent heat regenerator material 4 is in a liquid or semi-solid state.
