    • PURPOSE:To contrive to maintain the hot-water temperature intact after being boiled in a kettle without necessity of transferring the excessive hot-water into another heat insulation type vessel by a method wherein a sealing space surrounded by an inner vessel and an outer vessel is evacuated to make vacuum, and a refrigerant medium is sealed into said sealing space surrounded by the bottom part at both of the inner and outer vessels, and the lower vessel after said sealing space is evacuated. CONSTITUTION:A heat insulation hot-water heater is composed of an inner vessel 1 containing a water 7, a cylindrical outer vessel 2 surrounding the periphery side of the inner vessel 1, upper and lower ends of which is connected with said inner vessel 1, and cylindrical lower vessel 4 having a bottom, while the upper end of which is connected with said outer vessel 2. The inner vessel 1 and the outer vessel 2 are thermally separated by the vacuum heat insulation, a refrigerant 5 is sealed into the sealed space surrounded by a bottom part 3 of both of the inner vessel 1 and the outer vessel 2, and the lower vessel 4. As for the heat dissipating from a boiled hot-water 7, the heat dissipation caused by the convection toward the side surface can be prevented by the vacuum existing between the inner vessel 1 and the outer vessel 2. Although the space surrounded by the inner vessel 1, the outer vessel 2 and the lower vessel 4 is filled up with the refrigerant 5 and the gas, the heat source is located at the upper part of the vessel 4, thereby the convection does not occur, accordingly, the heat dissipation toward the lower surface can be prevented.
    • 目的:为了保证在水壶中煮沸之后保持热水温度不变,不需要通过其中由内容器和外容器包围的密封空间是过量热水转移到另一绝热型容器中的方法 抽真空以制冷,并且在所述密封空间被抽空之后,制冷剂介质被密封在由内部和外部容器两者的底部包围的所述密封空间中,下部容器被密封。 构成:隔热热水器包括内容器1,内容器1包含水7,围绕内容器1的周边的圆筒形外容器2,其内端与下容器1连接, 具有底部的圆柱形下部容器4,其上端与所述外部容器2连接。内部容器1和外部容器2通过真空隔热层热分离,制冷剂5被密封到密封空间 由内容器1和外容器2的底部3以及下容器4包围。对于从煮沸的热水7散发的热量,由朝向侧面的对流引起的散热可以 可以通过内部容器1和外部容器2之间的真空来防止。尽管由内部容器1,外部容器2和下部容器4包围的空间填充有制冷剂5和气体,但是热源 位于容器4的上部,因此不会发生对流,因此可以防止向下表面的散热。

    • PURPOSE:To effectively and speedily cool a milk bottle for adjusting the milk having a high temperature by installing an air-permeable water-containing filter at a cooling air introducing port, which is formed oppositely to the upper part of the milk adjusting bottle. CONSTITUTION:Boiling water 2 is poured into a milk bottle 1, and a cover 3 is applied, and said milk bottle 1 is arranged in a hot water feeding device body 4, and a switch is turned ON, and then a cooling fan 5 is revolved by an electric motor 6. Then, the cooling air is introduced into the body 4 from a cooling air introducing port 16, passing through a water-containing filter 12 installed on the upper part side surface of the body 4 as shown by the arrow A. After colliding with the upper part of the milk bottle 1, air flows downward through an air passage B and is discharged. Since, at this time, the cooling air is introduced on the peripheral wall of the milk bottle 1 by a rib 7, the milk bottle 1 is speedily cooled. Further, since the air taken in from outside passes through the water-containing filter 12, the milk bottle 1 is cooled by the vaporization heat of water, and thermal convection is accelerated.
