Description

Hybrid electric range that can be used without container classification {HYBRID ELECTRIC RANGE USEABLE REGARDLESS OF COOKING CONTAINER}

The present invention relates to an electric range, and more particularly, to a hybrid electric range capable of cooking even when various types of objects to be heated are placed at an arbitrary position.

Recently, when using a gas range, gas is incompletely burned, and substances harmful to the human body are dispersed into the air, adversely affecting the human body, or there is a risk of fire due to gas leakage and explosion due to gas being transported in a compressed state, fuel density As the problem of low efficiency due to fuel transmission is low, interest in electric ranges is increasing.

An electric stove is a device that converts electrical energy into thermal energy to cook food contained in a heating element. It can solve the risk of accidents due to harmful substances, the risk of gas explosion, and gas leakage, which are pointed out as problems with gas stoves. Electric ranges, unlike gas ranges, can have a simple appearance, particularly a flat top, and are installed in a built-in manner, which is advantageous for interior decoration.

The electric range is divided into an induction heater that heats through a high-frequency magnetic field using induction heating according to a heating method, and a highlight heater that transfers heat by directly heating a heating plate using electric resistance.

As power is applied to the induction heater, a high-frequency voltage of a predetermined size is applied to the working coil to generate a magnetic field around the working coil, and eddy currents inside the bottom of the heated object by the magnetic lines of force of the generated induced magnetic field ( EddyCurrent) is generated and the object to be heated is heated, thereby cooking.

In the highlight heater, when predetermined power is applied to a heating coil and high-temperature radiant heat is emitted by self-heating of the heating coil, the emitted radiant heat is directly transmitted to an object to be heated to cook food.

Since the highlighting method can only use non-metal objects to be heated, and the induction method can only use metal objects to be heated, there is a problem in that a user has to limit selection of a cooking vessel.

As a technology that integrates the induction method and the highlight method in order to solve the above problems, Patent Registration No. 10-1363250, an induction range having a heating source selection function (registration date: February 06, 2014) is disclosed.

However, the hybrid method of the prior art operates by allowing the user to select a heating method according to the type of object to be heated, but when the size of the object to be heated is smaller than the size of the heating source because the area where power is applied and heat is determined The heating source also heats the part other than the part where the heating object is placed, resulting in unnecessary power consumption. There is a problem with the length of time.

Registered Patent No. 10-1363250, induction range with heating source selection function (registration date: February 06, 2014) Registered Patent No. 10-1339945, electric range capable of fixing heating elements and measuring weight through selective heating and sizing (registration date: December 04, 2013) Patent Publication No. 10-2016-0004224, electric range (published on January 12, 2016)

The present invention is to solve the above problems, to provide an electric range that effectively heats the object to be heated by reflecting the size or shape when placing the object to be heated.

In addition, by selectively applying the heating method according to the material of the object to be heated, it is possible to have heating characteristics regardless of the type, and the optimum heat energy is delivered by changing the configuration and location of the heating source according to the shape and location of the object to be heated. To provide an electric range that can increase efficiency.

As an embodiment, a hybrid electric range is an electric range for heating a cooking vessel, comprising: a main body capable of placing a heating object on an upper plate; one or more heating sources provided to be movable within the body and heating the object to be heated; a sensing unit for determining the area, location, and material of the object to be heated; a drive unit for moving one or more of the heating sources according to the size and position of the object to be heated detected by the sensing unit; and a controller configured to control the driving unit to move the heating source according to the size and position detected by the sensing unit, wherein the sensing unit is composed of a pressure sensor and detects the position and area of the object to be heated, and the one The above heating sources have different sizes, and the driving unit drives one or more heating sources through free driving in a two-dimensional form to the position of the heating target detected by the sensing unit when the heating target is placed on the main body. The heating source has a highlight method as a direct heating member and an induction method as an indirect heating member in one heating source, the highlight method uses a heating coil, and the induction method is configured using a working coil, The working coil is formed in a form surrounding the heating coil from the outside, the sensing unit further includes a magnetic sensor, and controls the driving number and driving position of the heating source according to the area and position of the object to be heated, , When the material of the heating target is metal, the heating target is heated by an induction method, and when the heating target is made of a non-metal, the heating target is heated by a highlight method.

In the hybrid electric range according to the present invention, the induction heater and the highlight heater are used together in one heating source, so that the user can use them without distinguishing between the containers in the same way as the existing gas range, increasing convenience and avoiding pressure through a pressure sensor. By recognizing the area and location of the heating object and identifying the type of object to be heated through a magnetic sensor, the control unit implements a heating method suitable for the object to be heated through the heating source, so even if the object to be heated is placed at an arbitrary position, heating is not possible. Since it is possible to cook food by reflecting the size or shape of the object to be heated, the efficiency of cooking is improved.

In addition, by using a plurality of heating sources according to the area of the object to be heated or by using a heating source suitable for the area, energy can be efficiently utilized, thereby reducing consumption of electricity and reducing the time required for heating.
