Description

  The present invention relates to a container that can be cooled or heated by the same container for various articles that need to be kept cold or kept warm, and can be kept in a cold or kept warm state.

  Conventionally, a refrigerator is used to cool an article and maintain its cold state, while a refrigerator is used to heat the article and maintain its warm state, depending on its purpose. Has been. In addition, these refrigerators and warm storage rooms achieve their purpose mainly by circulating refrigerant, hot water, etc., and for that purpose, they are equipped with large-scale devices, and a large amount of various articles are simultaneously used. The purpose is to keep it cool and warm.

On the other hand, as in Utility Model Registration No. 3067049, there is known a compact cold insulation / heat insulation chamber in which the inside of a container is divided into two by a heat insulating partition and the upper part is used as a heat insulation and the lower part is used as a cold insulation.
Utility model registration No. 3067049

  The above-mentioned conventional large-sized refrigerators and warm storages are suitable for keeping many different articles at the same time in large quantities by using a refrigerant or hot water, but they are suitable for adding a small amount of specific articles. As a container for cooling or heating to maintain the cold or warm state, the efficiency is extremely poor. Moreover, since it has equipment for circulating refrigerant, hot water, etc., it has become a large storage item and is expensive. In addition, a refrigerator is required for cold storage, and a separate storage is required for keeping warm, and a large space is required as a storage place.

Further, as in the above-mentioned document, the inside of the container is divided into two parts, which can be kept cold and kept warm, the heating is performed by an electric heating plate and the cooling is performed by other means, and both devices need to be provided. Furthermore, the purpose of the division into two was that it was necessary to handle a wide variety of articles that needed to be kept cold or warm at the same time. If the articles specified in advance were kept cold or kept warm as in the present invention, it was necessary to divide into two parts. In addition, by devising the cooling / heating device, it is not necessary to provide two different devices.
The present invention solves the above-mentioned drawbacks, and efficiently cools and heats a specific article with the same container without maintaining a large-scale device for circulating a refrigerant, hot water, etc., and maintains the state. The present invention provides a small and lightweight cold and warm container that can be used.

  The present invention is composed of an article storage section and an openable / closable cover, and is characterized by a cold insulation / heat insulation container provided with a cooling / heating device with a plate having good heat conduction on the inner bottom of the article storage section. And

  Further, the cooling / heating apparatus is characterized by a cold insulation / heat insulation container provided with a Peltier effect element.

  The present invention enables various items selected from foods, side dishes, beverages, medicines, cosmetics, chemicals, towels, etc., to be cooled or heated in a single container, and kept cool or kept warm. is there. At that time, the temperature response was good, it was possible to immediately respond to cooling and heating, and it was possible to maintain that state.

  In addition, the miniaturization and weight reduction makes it easy to carry and the degree of freedom in use is significantly improved.

  Furthermore, since a Peltier effect element is used as a cooling / heating means, a refrigerant such as chlorofluorocarbon is not used, and the environment is not adversely affected.

  Hereinafter, the present invention will be described based on examples.

  FIG. 1 is a perspective view of a cold and heat insulating container of the present invention, and FIGS. 2 and 3 are a front view and a side view, respectively. The cold / warm container 1 includes an article storage unit 2 and an openable / closable cover 3. The article storage unit 2 has a cooling / heating device 4 at the bottom and an aluminum plate 5 at the upper part. ing.

  As the cooling / heating device 4, a Peltier effect element is used. FIG. 4 is a schematic diagram showing a Peltier module of a Peltier effect element. The Peltier effect element is a semiconductor element that can be cooled and heated, maintained in its state, and temperature controlled by a direct current.

  When a direct current is passed through the Peltier module, a temperature difference occurs on both sides of the semiconductor element. Heat is absorbed on the low temperature side, and heat is generated and radiated on the high temperature side. Accordingly, in the Peltier module, heat is transferred from the low temperature side to the high temperature side. In this state, the article placed in the upper part is deprived of heat and cooled.

  On the other hand, the direction of heat to be pumped can be reversed by changing the polarity of the current, and it becomes possible to heat the article placed in the upper part, which is the reverse phenomenon to the above.

  The strength of the cooling and heating can be changed by changing the magnitude of the current, the temperature control including the holding state is simple and the temperature responsiveness is good, and the article is immediately cooled or heated. It is possible.

  Further, the Peltier module does not use a refrigerant means such as chlorofluorocarbon and does not adversely affect the environment. Furthermore, since it is small and light, and there are no mechanical parts that are fatigued or damaged, it can have a long life and can have extremely high reliability.

  The aluminum plate 5 has good thermal conductivity, can immediately transmit cooling and heating to the article, and is effective in maintaining the state. As the material, a material having a thickness of about 2 mm whose surface side is subjected to anticorrosion processing by anodizing or the like is optimal. Replacement can be facilitated by providing the container 1 in a detachable manner.

  FIG. 5 shows a schematic view of the cooling / heating apparatus. A cooling / heating unit 6 is fixed to the lower part of the aluminum plate 5 and connected to a power source 7. A blower fan 8 is disposed on the side surface or the lower surface of the cooling / heating unit 6 to efficiently transmit the cold air or warm air from the cooling / heating unit 6 to the aluminum plate 5.

  By making the cover 3 transparent or translucent, the articles stored in the article storage unit 2 can be seen from the outside. The cover 3 can be opened by a pressing operation to the push-open hook 9 on the front side, and can be closed by a pressing operation to the main body side.

  By forming the bottom surface and side surface of the article storage unit 2 with a heat insulating material, it is possible to efficiently maintain the cold-insulated body. Further, the opening 10 and the fan 11 are formed on the inner side surface toward the inner space. The opening 10 is an inlet / outlet port for cold air or warm air, and the fan 11 can forcibly discharge odors or extra cold / warm air generated in the space inside the article storage unit 2 to the outside of the item storage unit 2.

  Similarly, by providing a thermometer or a room temperature detector 12 on the inner side surface and measuring the temperature of the storage space, it is possible to control the temperature in the storage portion 2 to be constant manually or automatically.

  A gallery 13 for introducing outside air or discharging cool / warm air inside the storage unit 2 is formed on the outer side of the main body forming the article storage unit 2. Inlet and exhaust are achieved by communicating with the opening 10.

  Further, a switch 14 connected to the power source 7 and a room temperature adjustment dial 15 are provided on the outer side. When the room temperature detector 12 is installed in the article storage unit 2, it can be automatically controlled to a preset room temperature by linking it with the temperature control device.

  In the above-described embodiment, the Peltier effect element is used as a means for cooling and heating. However, a cooling / heating apparatus without a refrigerant or the like can be used as necessary.
