Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a deep fryer for an electromagnetic cooker for general household use.

Conventional configurations and their problems Conventionally, when cooking tempura with an electromagnetic cooker, there is a type that adjusts the oil temperature by installing a sensor such as a thermistor on the underside of the top plate, but since it does not directly detect the oil temperature, A method has also been proposed in which the sensor is inserted into the container using a cord from the main body of the cooker, but it is inconvenient to store the cord and attach it to the container, or it is not installed correctly. It has drawbacks such as an abnormal rise in oil temperature.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned drawbacks and provides a deep fryer with high temperature control accuracy and high safety.

Structure of the Invention The present invention comprises a housing made of a non-metallic outer shell and a metallic container, and a first coil provided at the bottom of the outer shell, and a DC power source obtained from both ends of the first coil. a power supply device, an electronic thermostat driven by the power supply device, and a second coil connected to the first coil via the electronic thermostat and provided for heating the metal container. It is something.

DESCRIPTION OF THE EMBODIMENTS In FIG. 1, 1 is a non-metallic outer shell, and 2 is a metallic container. A first coil 3f is provided at the bottom of the outer shell, an electrically insulating magnetic material (ferrite core) 4 is provided at the top of this coil 3, and a second coil 3f is provided at the bottom and peripheral portion of the container 2.
A coil 5 is provided.

Furthermore, a sensor support member is attached to the inner lower part of the container 2. 6 is an electronic thermostat consisting of an electronic circuit, and 8 indicates a knob for controlling the temperature. FIG. 2 shows an electrical wiring diagram, and the parts corresponding to the electronic thermostat described above are indicated by symbols 10 to 14. 9
is a DC power supply device consisting of a resistor, a diode, and a capacitor, and includes a thermistor 1 attached to a sensor support 7.
It is used to drive a transistor circuit 12 (details not shown) and a relay 13 whose inputs are 0 and a temperature adjustment variable resistor 11 operated by a knob 8.

Relay contact 14 is connected between first coil 3 and second coil 6. 16 is a temperature fuse.

When the deep fryer with the above configuration is mounted on the top plate of an electromagnetic cooker so that the first coil 3 faces the heating coil of the electromagnetic cooker and the electromagnetic cooker is operated, the first coil 3
AC high frequency voltage is induced. This voltage causes the power supply device 9 to generate a DC voltage, and if the oil temperature is lower than the set value, the relay coil 13 is energized, the contact 14 is closed, and the second
The second coil 5 is energized to heat the container 2 using the principle of induction heating to raise the temperature of the oil in the container, and when the oil temperature reaches a level higher than the set value, the contact 14 is closed and the second coil 6 is turned off. Energize and stop heating operation. This operation is repeated to maintain the oil temperature at a predetermined temperature. Here, the magnetic body 4 is provided to improve the coupling between the coil 3 and the heating coil of the electromagnetic cooker.

As is well known, electronic thermostats have a small thermal capacity of the sensor, and the operation [IJ (ON-〇FF)] can be made arbitrarily small, so they have lower temperature accuracy and temperature ripple than mechanical ones such as liquid expansion type. It is possible to obtain small temperature control. However, whereas a mechanical type uses the thermal energy of the object to be controlled for its operation, an electronic type requires a separately prepared power supply device.

Effects of the Invention The main point of the present invention lies in this point. Instead of directly heating the container with the electromagnetic cooker, the first coil receives and receives the stain energy from the electromagnetic cooker and converts this electric energy into The system is configured so that a driven electronic thermostat is provided, and this thermostat controls the energization of the second coil provided to heat the container, so as mentioned above, the temperature accuracy is good and the temperature ripple is small. ,
Moreover, when a large amount of food is put into cooking, it responds quickly to the drop in oil temperature, which not only does not have a negative effect on the finish of the cooking, but also prevents the oil temperature from dropping if the sensor is attached or forgotten even though the sensor is fixed. Therefore, it is possible to provide a deep fryer which is excellent in safety without causing an abnormal temperature rise, and is cordless and easy to use.

In addition, in the embodiment, the electronic thermostat is IJ
Although the L/- coil 13 and the contact point 14 control the energization of the second coil 5, a semiconductor element may be used instead. If the distance is made sufficiently wide, the magnetic body 4 becomes unnecessary.
