Description

Electric range

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric range, and more particularly, to an electric range in which a current position of a heating container can be easily calculated.

2. Description of the Related Art In recent years, an electric range (so-called highlight range) has been developed and used in which food is cooked by heating a heating element by electricity in order to provide comfortable indoor air while eliminating the above-mentioned disadvantages of the gas range.

Unlike a gas range, such an electric range does not have a risk of gas explosion due to gas leakage, and provides pleasant indoor air with no smell. In addition, unlike a gas range, an electric range can have a simple appearance, in particular, a flat upper surface, which is very advantageous to be installed in a built-in manner.

That is, since the electric range is formed in the form of a flat plate with the upper plate closed, the heat generated in the highlight heater can be heated by the heat heated in the upper plate and the heat transmitted through the upper plate after primarily heating the upper plate .

In recent years, when the top plate is formed of a flat plate type, that is, a reinforced glass material, when water or grease is applied to the surface or the bottom of the heating container, the heat generated by the heating container slipping on the top plate is transferred to the heating container Heat can not be generated due to heating, and therefore research is underway to prevent this.

The object of the embodiment is to provide an electric range in which the current position of the heating container can be calculated.

Another object of the embodiment is to provide an electric range in which it is possible to determine the supply of electric power for generating heat in accordance with whether or not the current position of the heating container belongs to the set reference position range.

According to an embodiment of the present invention, there is provided an electric range including a sensor module for outputting an electric signal corresponding to a load acting on the heating container when the heating container is placed on a flat plate covering an opened upper surface of the case, And a control module for calculating a current position of the heating container in the flat plate based on the electric signal and the electric signal.

The flat plate may further include first and second counterparts corresponding to the first and second heating plates disposed in the case, respectively, and may further include a power module for supplying power to the first and second heating plates.

The power supply module may vary the power supply level of the power supply according to the control of the control module.

The sensor module includes first to fourth sensor units for outputting first to fourth sensor signals corresponding to loads acting on the heating vessel in first to fourth corner regions of the flat plate, And a sensor output unit for outputting the electrical signal including the fourth sensor signal.

Each of the first to fourth sensor signals may include a sensor ID of each of the first to fourth sensor units and a magnitude value corresponding to the load.

The sensor output unit may output the electric signals obtained by combining the sensor IDs included in the first to fourth sensor signals according to a predetermined sensor ID sequence.

Wherein the control module includes a change amount calculating unit that calculates a change amount between the previous electric signal and the electric signal, a position calculating unit that calculates a current position of the heating container in accordance with the change amount, And a control unit for controlling the power supply module so that the power supply level of the power supplied to the first and second heating plates varies according to whether the power supply module belongs to the first or second heating plate.

Wherein the change amount calculation unit compares first to fourth previous sensor signals included in the previous electrical signal and first to fourth sensor signals included in the electrical signal to calculate the change amount including the first to fourth change amounts, Can be calculated.

The position calculation unit may calculate the current position of the heating container with at least one of the first to fourth variation amounts included in the variation.

The control unit can control the power level of the power supplied to the first and second heating plates to be maintained when the current position of the heating vessel belongs to the reference position range corresponding to the first and second openings.

The control unit may decrease the power supply level of the power supplied to the first and second heating plates if the current position of the heating vessel does not belong to the reference position range corresponding to the first and second fireboxes, 2, the power supplied to the heating plate can be controlled to be shut off.

The electric range according to the embodiment can be realized by heating the heating container by sensing the movement or position change of the heating container on the basis of the electric signal corresponding to the load of the heating container placed on the flat plate in the edge area of the plate- There is an advantage in that the electric loss can be reduced by determining whether or not the power supply is supplied to the heating plate that generates heat in order to make the power supply.

In addition, in the electric range according to the embodiment, when the heating container placed on the flat plate is lifted and removed, the electric power supplied to the heating plate can be automatically shut off, thereby improving the user's convenience in use.
