ELECTRIC RANGE FOR FIXING HEATER AND MEASURING WEIGHT BY SELECTIVE HEATING AND SIZE ADJUSTMENT}

The present invention relates to an electric range, and in particular, to increase the thermal efficiency delivered by attaching a heater directly to the tempered glass, and to make the selective heating according to the size of the cooking vessel to contact the contact surface to reduce the power consumption even more than conventional products In order to fix the cooking vessel to be heated or to prevent slipping, the contact surface enters according to the size so that the cooking vessel does not slip easily, and a weighing sensor is placed on the bottom of the electric range to weigh the cooking vessel. The invention relates to an electric range capable of fixing and weighing the heating elements through selective heating and sizing that makes it easy to scoop up and provide the convenience of having the correct weighing value for cooking.

In recent years, in order to provide comfortable indoor air while eliminating the above disadvantages of the gas range, an electric range (aka, highlight range) has been developed and used for cooking food by heating a heating element by electricity. Unlike a gas range, this electric range offers no risk of gas explosion due to gas leakage and provides a pleasant odorless indoor air. 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.

As shown in FIG. 1, the conventional electric range has a predetermined space for mounting the main body 10, the plurality of heater assemblies 20, the power supply unit 30, and the control assembly 40.

First, the main body 10 is formed of a rectangular case having an upper surface open and a space portion provided therein. At this time, the upper plate 50 is installed in the upper surface opening of the main body 10, the upper plate 50 is configured to block the space formed by the main body 10 from the outside, formed of tempered glass such as ceramic glass do.

Various cooking vessels are mounted on the upper surface of the upper plate 50 in correspondence with the mounting position of each heater assembly 20, and form a cooktop portion of an electric range.

The heater assembly 20 is provided in the front space and the rear space in the main body 10, respectively, and serves to cook food while generating heat by power supply.

In addition, the heater assembly 20 generally includes an outer case 24 forming an outer shape, a base 21 and a hi-light heater 22 installed inside the outer case 24.

In addition, the heater assembly 20 is provided with a temperature sensor 23 for sensing the temperature.

Meanwhile, one end of the power supply unit 30 is exposed to the outside of the bottom of the main body and the other end of the power supply unit 30 is exposed to the inside of the main body, and receives external power to the heater assembly 20 and the control assembly 40. It serves to supply power, and a plurality of power lines 31 are drawn out.

The control assembly 40 is configured to perform operation control of each heater assembly by a user's manipulation.

The control assembly 40 includes at least one substrate 41 on which circuit components for various operations or control are mounted, and a case body 42 having a predetermined accommodation space for mounting the substrate 41. .

In this case, a cut hole 42a is formed at a portion of the case body 42 that is in contact with the space where the heater assembly 20 is provided, and the power supply unit 30 is provided through the cut hole 42a. A power line 31 drawn from the through is connected to the substrate.

However, since such a conventional electric range is formed in a closed form of the top plate, since the heat generated from the highlight heater primarily heats the top plate and then heats the cooking vessel by heat heated in the top plate and heat passing through the top plate. There is a severe heat loss problem.

In addition, such a conventional electric range has another problem that the upper plate is made of a tempered glass material so that water or grease splashes on the surface or slips easily when the water or grease splashes on the bottom of the cooking vessel.

In addition, such a conventional electric range has another problem that must use a separate scale or improved cup if you want to measure the correct measurement amount for cooking because there is no function to measure the weight separately.
