Description

  The present invention relates to a cold insulation system using cold air from a refrigerator, and more particularly, to a cold insulation system used for storing food that needs cold preservation in a kitchen.

In recent years, in Japan, with the diversification and internationalization of food culture, the capacity to store food products tends to increase.
In order to respond to this trend, developments such as increasing the size and capacity of refrigerators have been promoted, but the large refrigerator requires a considerable amount of installation space. There is a limit to securing it.

  Therefore, it has been common to select a food that does not rot even if the storage temperature is relatively high, and store the food by installing a storage built in the system kitchen, a storage under the floor, or a food shelf.

  For such a problem, Patent Document 1 discloses a system kitchen built-in refrigerator. That is, the refrigerator described in Patent Document 1 is a drawer-type refrigerator installed in a part of a system kitchen, and cooling units are also concentrated and arranged together.

  Patent Document 2 discloses an underfloor storage with a cooling function that is compact and easy to incorporate into an underfloor space. The underfloor storage with cooling function has a Peltier element attached to the outer peripheral surface of the box (storage part), and a heat radiating fin and a heat radiating fan are arranged outside the Peltier element. Other than the dedicated power supply unit and Peltier element The part is covered with a heat insulating material.

  Furthermore, Patent Document 3 discloses an assembly-type refrigerator that can be assembled by freely arranging quantities and arrangement positions as necessary. The assembly-type refrigerator is a refrigerator including a main box that generates low-temperature gas (cold air), boxes connected by a connecting and fixing device, an air duct that sends cold air, a compressor, and a fan.

  However, in the system kitchen built-in refrigerator described in Patent Document 1, since a dedicated cooling unit is arranged, a dead space is required, and there is a problem that the space cannot be used effectively. There is also a problem that the kitchen itself is heated in order to exhaust the warmed gas from the cooling unit.

  In addition, the underfloor storage with a cooling function described in Patent Document 2 uses a dedicated power supply unit and uses a Peltier element as a cooling method, and therefore requires a relatively large amount of power consumption. there were.

  Furthermore, although the assembly-type refrigerator described in Patent Document 3 can select the number of installations as necessary, it is the same as adding a small refrigerator, and effectively uses the space in the kitchen. From the viewpoint, improvement of the problem cannot be expected.

  The present invention has been made in view of the above problems, and a specific object of the present invention is to provide a cold insulation system that effectively uses the cool air of the refrigerator and uses the space in the kitchen as a cold storage. .

The present invention has been devised to achieve the above object. If it explains in full detail, the cold air supply means which consists of the refrigerator which produces | generates cold air, the cold air supply port which supplies cold air from this refrigerator, and the switching valve which distributes cold air in communication with this cold air supply port, and communication with this cold air supply means A conveying means for conveying cold air to the cold storage, a cold storage in which the object to be cooled is stored and a vacuum heat insulating material is embedded in the heat insulating material, and gas in the cold storage from the cold storage to return to the refrigerator A cold insulation system comprising an air circulation means, wherein the cold air supply means, the cold air conveying means, and the air circulation means are arranged under the floor of the kitchen.
In addition , the cool box is provided in the side surface of the inner wall near the intersection where the upper surface and the front surface of the inner wall intersect, and in the vicinity of the intersection point where the upper surface of the inner wall and the rear surface intersect on the side surface of the inner wall of the cool box. A structure having an exhaust port for returning the gas in the cool box disposed in the refrigerator to the refrigerator, and a cold air guide groove formed in a spiral shape on the inner wall of the cool box connecting the cold air intake port and the exhaust port. included.

In the cold insulation system of the present invention, since the cold air of the refrigerator is used, there is no need for a space for installing a cooling device for each cold storage, and it is possible to effectively use the space by arranging the cold air conveying means under the floor. An effect is obtained.
Further, in the cold insulation system of the present invention, the cold air inlet is disposed in the vicinity of the upper surface of the inner wall of the cold storage, and is further formed in a spiral shape extending from the side surface to the upper surface, from the upper surface to the side surface, and from the side surface to the bottom surface. Because it communicates with the cool air guiding groove, the cool air supplied from the refrigerator becomes a spiral flow, and the effect of making the entire cool box at a substantially uniform temperature is obtained. The relatively warm gas that accumulates in the upper part of the cabinet can be returned from the exhaust port to the refrigerator via the air circulation means.

  The present invention includes a configuration in which the cold storage is embedded in the storage under the floor of the kitchen.

  Since the cold-reserving system of the present invention has a structure in which the cold-reservoir is embedded in the underfloor storage, if the underfloor storage is added, there is an effect that the cold insulating space can be increased relatively easily.

  Furthermore, the present invention includes a configuration in which the cold storage is installed in a part of the system kitchen.

  Since the cold storage system of the present invention is configured so that the cold storage is installed in a part of the system kitchen, the existing space can be used effectively as a cold storage, and is installed in the cold air supply means when unnecessary. By closing the switching valve, there is an effect that it can be used as a normal storage.

  In this invention, it has the inner storage container detachably accommodated in the said cool box, and has a space | interval which can distribute | circulate cool air between this inner storage container and the inner wall of the said cool box. Configuration is included.

  The cold-reserving system of the present invention has an effect of preventing the object to be cooled from blocking the flow of the cold air in the cool box and efficiently using the cool air to keep the temperature in the cool box uniform.

  The cold-reserving system of the present invention has an effect of being able to cope with an increase in the storage capacity of foodstuffs by efficiently using the cold air of the refrigerator and using the space in the kitchen as a cold-reservoir.
