Abstract

A container support is disclosed. The container support is operated in conjunction with an induction heating unit, which is disposed beneath a table and generates a magnetic field, and includes a plate for supporting a cooking container placed thereon, a manipulation unit provided at a portion of the plate so as to receive control commands from a user, and a signal-transmitting part provided at a portion of the plate so as to transmit electric signals to the induction heating unit.

First claim

The invention claimed is:

1. A container support configured to be operated in conjunction with an induction heating unit,
wherein the induction heating unit is fixed beneath a table, is configured to generate a magnetic field, and includes:
a working coil configured to generate the magnetic field by receiving current, and
a signal receiver configured to receive electric signals,

wherein the container support comprises:
a plate for supporting a cooking container placed thereon;
a manipulation unit provided at a first portion of the plate and configured to receive control commands from a user;
a magnetic field sensor provided at the plate to detect an intensity of the magnetic field generated by the working coil; and
a signal transmitter provided at a second portion of the plate and configured to transmit electric signals to the signal receiver of the induction heating unit,

wherein the container support is at least horizontally movable independent of the induction heating unit, a horizontal direction being a direction parallel to a top surface of the table,
wherein the container support is provided above the table, and
wherein the table is provided between the container support and the induction heating unit.

2. The container support according to claim 1 , wherein the plate is made of a heat-resistant material, the heat-resistant material being one of heat-resistant synthetic resin, silicon, and glass.

3. The container support according to claim 1 , further comprising:
a display unit provided at a portion of the plate and configured to display cooking information to a user.

4. The container support according to claim 3 , further comprising: a temperature sensor provided at the plate to measure a temperature of the cooking container.

5. The container support according to claim 4 , wherein temperature information detected by the temperature sensor is transmitted to the induction heating unit through the signal transmitter, and the induction heating unit adjusts the intensity of the magnetic field depending on the temperature information transmitted thereto.

6. The container support according to claim 4 , wherein the induction heating unit includes:
a power supply part for supplying current to the working coil; and
a controller connected to the signal receiver and the power supply part.

7. The container support according to claim 6 , wherein temperature information detected by the temperature sensor is transmitted by the signal transmitter to the signal receiver and the controller, and the controller controls the power supply part based on the detected temperature information, thereby adjusting the intensity of the magnetic field generated by the working coil.

8. The container support according to claim 3 , further comprising:
a power supply part for supplying power to the signal transmitter or the display unit.

9. The container support according to claim 8 , wherein the power supply part is configured to generate induced electromotive force from the magnetic field generated by the induction heating unit and to use the induced electromotive force as a driving force.

10. The container support according to claim 1 , wherein the magnetic field sensor comprises a plurality of magnetic field sensors, and
wherein the plurality of magnetic field sensors are spaced at a predetermined distance apart from a center portion of the plate.

11. The container support according to claim 9 , wherein the power supply part comprises:
a receiving coil configured to generate induced current from the magnetic field generated by the working coil, and
a charger configured to store power generated by the receiving coil.

12. The container support according to claim 11 , wherein the charger is connected to the signal transmitter or the display unit, and transmits the stored power to the signal transmitter or the display unit to drive the signal transmitter or the display unit.

13. The container support according to claim 3 , wherein the display unit is configured to display information instructing the user to shift the container support towards a position where the intensity of the magnetic field detected by the magnetic field sensor is relatively high.

14. The container support according to claim 13 , wherein the information displayed on the display unit is represented by arrows or characters indicating directions.

15. The container support according to claim 3 , wherein the display unit is configured to display information instructing the user to shift the container support towards a position where the intensity of the magnetic field detected by the magnetic field sensor is highest.

16. The container support according to claim 1 , wherein the table has a surface without a recess.

17. The container support according to claim 1 , wherein the container support is horizontally movable on the table without obstruction.
