Temperature controllable electric grill {ELECTRIC GRILL CAPABLE OF CONTROLLING TEMPERATURE}

The present invention relates to a temperature-controllable electric grill, and more particularly, to a temperature-controllable electric grill that can be cooked evenly without burning food by controlling the heating temperature and time of the grill plate.

In general, electric grills are used for roasting food materials such as meat, fish, and vegetables, and are devices that use electricity as an energy source to install a heating heater and adjust the heating value of the heating heater with a temperature controller to cook food materials.

Recently, the electric grill has been widely distributed to each consumer as a solution to health problems due to the convenience of use, fire risk, and carbon monoxide generation. Also, the quality of life has been improved and the diet has become westernized, which is the level of simply roasting meat on a frying pan. The demand for electric grills is gradually increasing due to the use of electric grills when a large amount of grilled food is enjoyed with friends and family, or when a large amount of cooking is required for various holidays.

As shown in FIG. 1, the electric grill controls the heating plate 1 on which food ingredients are placed, the heater 2 that generates heat by converting electrical energy into thermal energy, and the heater 2 that generates heat. A temperature control unit 3 that supports the heater 2 and the temperature control unit 3 and receives the oil generated on the grilling plate 1, and the lower surface of the discharge support plate 4 It is composed of a ground fixing tool (5) made of rubber material protruding and fixed at the corners so as to be seated on the ground.

This conventional electric grill has a simple structure and can be used conveniently by the user, but it is a structure in which a circular heater 2 is welded to the lower side of the grilling plate 1 and has a simple heater shape and has a large temperature deviation, so the entire grilling plate is There was a problem in that the food was not cooked well because heat was not transmitted evenly to the oven.

In addition, although there is a temperature control unit that controls the temperature, it is set in approximately five stages, so the heating temperature of the grilling plate cannot be accurately known during the cooking process, and there may be a problem of overheating. There is a problem in that the efficiency and safety of cooking are deteriorated by not managing the temperature deviation of

In addition, in the case of cooking meat, the conventional electric grill collects a large amount of oil in the outflow support plate 4 through the outlet 6 penetrating the side of the grilling plate 1, but there is a cumbersome problem that must be removed separately. , There was also a problem that the oil generated from the grilling plate (1) could not be guided and thus could not be discharged smoothly.

Accordingly, the present invention has been devised to solve the above problems, and its object is to change the shape of the heater at the lower portion of the grill plate to facilitate heat transfer as much as possible, and attach a temperature sensor to display the sensed temperature on the temperature display unit. As a result, the entire heater heats up uniformly and heat is evenly transferred to the front of the grill plate, maximizing cooking efficiency and preventing excessive heating to provide a temperature-controllable electric grill that can minimize the generation of ultrafine dust and carcinogens. I can.

A temperature controllable electric grill according to an embodiment of the present invention for achieving the above object includes a grill plate on which food is placed, a heater provided under the grill plate to generate heat for the grill plate, and a lower portion of the grill plate. A temperature sensor provided on the grill plate to detect a heating temperature of the grill plate according to the heat generated by the heater, and a control unit provided on the side of the grill plate to display and set a temperature transmitted to the grill plate.

It may further include an ultrafine dust measuring device provided on the upper portion of the grill plate to measure the ultrafine dust generated when the food is burned.

A cutout may be formed on a side surface of the grill plate, and an oil tray may be provided under the cutout to receive oil of cooking.

The grill plate may be provided in an inclined manner so that the oil generated from the cooking material flows down to the cutout portion and can be collected into an oil pan.
