  The thing of this patent document 1 is changing the direction of the electric current which flows into a Peltier device to a normal direction and a reverse direction, and swaps the position of a heat absorption surface and a heat dissipation surface, and heats or cools a beverage. It is. In this heating / cooling device, a beverage placed in a container is placed in a cylindrical portion to heat or cool the beverage, but a power cord is required to supply power to the electronic cooling portion. When carrying the cooling device itself, it is necessary to attach / detach the power cord to / from the outlet, which is troublesome, and this power cord is an obstacle.

  In view of the above, the present invention uses an electronic cooling / heating element such as a Peltier element for cooling an object to be cooled such as a beverage in order to provide a cooling device that does not require a power cord. As a power source, a simple cooling device that can use an electromagnetic induction heating device that is widely used as a facility for kitchens and dining rooms is provided.

A cooling device according to a first aspect of the present invention includes a cooling device having a configuration in which a high-frequency induction magnetic field generating coil is provided on the back side of a pedestal that is a kitchen top plate or a dining table plate, and a main body is detachably mounted on the pedestal. The main body has an operation part in the lower part and a cup-shaped container part that can be carried with one hand for storing beverages and the like in the upper part. The operation part generates induced power by the magnetic field of the high-frequency induction magnetic field generating coil. A passive-side coil, an electronic cooling element that operates by direct current based on a current generated by the passive-side coil, a circuit board and a heat-dissipating fan, and a heat-dissipating heat sink for the electronic cooling element, and a receiving opening for the upper surface opening of the operating part The actuating part and the container part are separable in a configuration for receiving the bottom part of the container part, and a thin electrical insulating material is provided on the upper surface of the heat absorbing part of the electronic cooling element. The heat conducting plate joined together forms the bottom surface of the receptacle, and the bottom portion of the container portion is fitted to the receptacle so that the bottom wall of the container portion contacts the thermal conducting plate. An object to be cooled such as a beverage stored in a container part is cooled .

According to a second aspect of the present invention, there is provided a cooling device according to the first aspect, further comprising: a display unit that lights and displays the operation of the cooling device by the direct current on the outer surface of the operating unit; and an object to be cooled such as a beverage on the outer surface of the container unit. The temperature display part is provided.

In the first aspect of the invention, an electronic cooling element such as a Peltier element is activated by the induced power generated when placed in the magnetic field of a high-frequency induction magnetic field generating coil disposed on the back side of a pedestal that is a kitchen top plate or dining table plate. Since the object to be cooled such as the beverage in the container is cooled, no power cord is required. For this reason, it is convenient to carry the cooling device, and the range of use of the electromagnetic induction heating device that is widely used as facilities such as kitchens and dining areas is expanded. In addition, the main body that is detachably mounted on the pedestal having the high-frequency induction magnetic field generating coil includes a lower operation part and an upper container part for accommodating an object to be cooled, so that the center of gravity of the cooling device is lowered and stabilized.

Moreover, since the container part can be removed and washed with water, in this case, it is safe without water splashing on the lower working part. Furthermore, since the same direct current as the electric power to the electronic cooling element is used for the electric power to the heat radiating fan, the electric cooling element can be supplied with power by placing the main body on a pedestal equipped with a high frequency induction magnetic field generating coil. Since power can be supplied at the same time, a power cord for supplying power to the heat radiating fan is not necessary, and ON / OFF control by a switch is not necessary, and the usability is convenient. Furthermore, since the container portion has a cup shape that can be carried with one hand, it is convenient to carry and easy to use.

In addition to the effects of the first invention, the second invention is convenient because it is easy to determine whether or not the object to be cooled stored in the container is at an appropriate temperature and to confirm whether the cooling device is operating. In addition, since the display unit that lights and displays the operation of the cooling device provided on the outer surface of the operation unit is operated by direct current based on the current generated by the passive side coil, the use of the LED simplifies the power feeding circuit. Further, since the light is turned off when the cooling device is taken up, ON / OFF control by a switch is not necessary, and the usability is convenient.
