- the ceramic plates 5 and 6 are attached to the electrode plates 3 and 4 respectively to make the Peltier module A.
- a closed loop circuit is formed by the conductor 8 via the diode 7 between the electrode plate 3 at the start and end.
- Embodiment 1 of the present invention When the Peltier module A having the above configuration is placed on the top plate 11 of the induction electromagnetic controller, a magnetic force is generated by a high-frequency current flowing in the magnetic force generating coil 12 (see FIG. 2) provided at the bottom of the top plate 11. An alternating magnetic field perpendicular to the generator coil 12 is generated. This alternating magnetic field induces a current in a closed-loop circuit composed of the Belletier module A, the diode 7 and the conductor 8, and is rectified by the diode 7 to be connected to the P-type semiconductor 1 that is each Peltier element of the Peltier module A. One-directional direct current flows through the N-type semiconductor 2 and the surface side is cooled. When a pan or container is placed on Peltier module A, the food in the pan or container is rapidly cooled.
- a coil 9 is provided below the Peltier module A, and the coil 9 is connected to the Peltier module A via a conductor 8 and a diode 7.
- the closed loop circuit formed outside the Peltier module A is equivalent to one turn.
- the coil 9 is made up of several turns, thereby generating a magnetic force generating coil. 12 (see Fig. 2), the number of interlinkages of the magnetic field generated is increased to amplify the induced electromotive force. This is based on the action of a transformer coupled by a force alternating magnetic field between the magnetic force generating coil 12 and the coil 9. This increases the cooling efficiency of the Peltier module A and increases its practicality.
- the Peltier element has a side to be cooled and a side to be heated by the movement of heat. Therefore, the electrode plate 3 on the side opposite to the cooling side is heated. For this reason, the heat on the electrode plate 3 side is transferred to the electrode plate 4 on the cooling side, causing a phenomenon that the cooling side does not cool above a certain temperature. Therefore, as shown in the embodiment of FIG.
- a non-magnetic heat radiation plate 20 such as aluminum is attached to the lower surface of the Peltier module A, and is fixed to the upper surface of the case 21 formed of a non-metallic material such as plastic.
- a coil 9 having several turns is disposed so as to be close to the top plate 11 of the induction electromagnetic cooking device, and a container 24 containing water or other refrigerant 23 is stored.
- a radiator 25 is installed outside the case 21, and the refrigerant 23 radiates heat through the circulation pipe 26.
- a power source such as a cooling fan (not shown) of the radiator 25 can be used as a power source by conducting a high frequency current induced in the coil 9 through the electric wire 27 and rectifying it.
- the installation area can be reduced by storing the radiator 25 and the circulation pipe 26 in the case 21. With this configuration, the user is freed from the trouble of arranging the radiator 25 and the circulation pipe 26 around the case 21 for each use.
- the Peltier module A one or a plurality of commercially available ones can be configured. For example, if 12 units for 12V, 6Amax, maximum heat absorption 57W are used, the total power consumption is 864W, but this power can be covered by the generated high frequency magnetic field from the electromagnetic induction heating cooker of 600-800W ( The output of a typical electromagnetic induction heating cooker is over 1000W).
- the Peltier module A has a maximum operating temperature of 150 ° C, which is lower than the temperature at which the solder melts. Therefore, when it is cooled with water, it does not exceed 100 ° C and is safe.
- the temperature on the cooling side is calculated to be -22 ° C when the heat generation side is 50 ° C, and there is a sufficient cooling effect.
- the upper part of the Peltier module is used as a heating surface. If an electromagnetic induction heating cooker is placed on a metal material having an appropriate electrical resistance, such as iron, heat is generated based on the generation of Joule heat due to eddy current. This means that a pan or container made of an insulating material such as glass does not generate heat even when using an electromagnetic induction heating cooker.
- a glass pan or the like placed on the heat generating surface.
- the electromagnetic induction heating method is intended for heating and is not suitable for keeping food warm. Therefore, even if the temperature setting is adjusted to a low level, the temperature will be about the level of “fire”, and if the pan is left on for a long time, the cooked food may burn in some cases.
- the upper surface of the Peltier module of the present invention as a heat generating surface, it is possible to keep the heat at a low temperature and to keep the food warm for a long time so that the food is not cooled.
- the Peltier bowl module of the present embodiment is integrated with the bottom of the pan. Thereby, the cooling pan only for an electromagnetic induction heating cooking appliance can be provided.
- frozen desserts such as ice cream, sherbet, and pudding as desserts
- they are cooled so that they do not melt or rise in temperature.
- a magnetism generating coil is placed at the bottom of the conveyor, and a plate or tray with a Peltier module embedded at the bottom is placed on the top of the conveyor and moved to move sushi and cooking while on the move. The freshness can be maintained while cooling the object. Cooked dishes that you do not want to cool can be handled by using regular dishes.
- the present invention uses an induction current generated by a high-frequency induction magnetic field, which is the heat generation principle of an electromagnetic induction heating cooker, and is suitable for household and commercial kitchen appliances as a technology that can use a Peltier element as a cooling device. Can be used.
