Abstract

Provided is a cooking apparatus including a first heating unit that has a first hole and generates heat using a first heat source, a second heating unit that is arranged to be stacked on the first heating unit, has a second hole formed at a position corresponding to the first hole, and generates heat using a second heat source, and a temperature detection unit that is arranged to protrude to the outside of the second hole while being arranged in the first hole of the first heating unit and the second hole of the second heating unit, and detects a temperature of a cooking vessel when the cooking vessel is brought into contact with the temperature detection unit. The output of each of the first heating unit and the second heating unit is controlled at levels of multiple stages by detecting a temperature of a lower portion of the cooking vessel, and food is cooked at an optimum temperature, thereby improving the taste of the food resulting in improved user satisfaction. The first heating unit and the second heating unit is operated together, so that it is possible to prevent emission of the heat of the second heating unit to the outside by the heat generated by the first heating unit, thereby reducing energy consumed in the second heating unit while increasing the heating rate.

First claim

What is claimed is:

1 . A cooking apparatus comprising:
a first heating unit that has a first hole and generates heat using a first heat source; a second heating unit that is arranged to be stacked on the first heating unit, has a second hole formed at a position corresponding to the first hole, and generates heat using a second heat source; and a temperature detection unit that is arranged to protrude to the outside of the second hole while being arranged in the first hole of the first heating unit and the second hole of the second heating unit, and detects a temperature of a cooking vessel when the cooking vessel is brought into contact with the temperature detection unit.

2 . The cooking apparatus according to claim 1 , wherein the second heating unit is arranged to be spaced apart from the first heating unit.

3 . The cooking apparatus according to claim 1 , wherein the temperature detection unit includes
a sensing portion that protrudes to the outside of the second hole and detects the temperature of the cooking vessel, a guidance portion that is connected to the sensing portion, receives a signal line of the sensing portion, and is movably arranged inside the first hole and the second hole, and an elastic member that elastically supports the guidance portion, and wherein a size of the sensing portion is smaller than a size of the second hole.

4 . The cooking apparatus according to claim 3 , wherein the guidance portion further receives a communication line and a power line of the second heating unit.

5 . The cooking apparatus according to claim 1 , wherein the second heating unit includes
a heat generation unit that generates heat using electrical energy, a housing that receives the heat generation unit, and an insulation portion that is arranged adjacent to the housing, and prevents emission of heat generated by the heat generation unit.

6 . The cooking apparatus according to claim 1 , wherein the second heating unit includes
a heat generation unit that generates heat using electrical energy, a housing that receives the heat generation unit, an insulation portion that is arranged between the first heating unit and a lower surface of the housing and prevents emission of heat generated by the heat generation unit, and a panel that is arranged adjacent to an upper surface of the housing, wherein the insulation portion, the housing, and the panel are arranged to be stacked on top of one another and respectively have the second hole, and wherein the temperature detection unit is moved to the same position as that of an upper surface of the panel while being moved to the inside of the second hole of the panel, when the temperature detection unit is pressurized by the cooking vessel.

7 . The cooking apparatus according to claim 6 , wherein the second heating unit further includes a fixing member that is arranged between the housing and the panel and connects the housing and the panel.

8 . The cooking apparatus according to claim 6 , wherein the second heating unit further includes a fixing member that is arranged between the housing and the panel and elastically supports the panel.

9 . The cooking apparatus according to claim 1 , further comprising:
a storage unit that stores output levels of multiple stages which are set by a combination of a heating level of the first heating unit and a heating level of the second heating unit; an input unit that receives one output level of the output levels of multiple stages; and a control unit that controls the heating level of at least one of the first heating unit and the second heating unit based on the received output level.

10 . The cooking apparatus according to claim 9 , further comprising:
a communication unit that performs communication with an external device, wherein the control unit controls the communication unit so that operation information of each of the first heating unit and the second heating unit is transmitted to the external device, and controls each of the heating level of the first heating unit and the heating level of the second heating unit based on cooking information received by the communication unit.

11 . The cooking apparatus according to claim 1 , further comprising:
a communication unit that performs communication with an external device; and a control unit that controls the communication unit so that the detected temperature is transmitted to the external device.

12 . The cooking apparatus according to claim 1 , further comprising:
a control unit that controls output of alarm information when the detected temperature is a limit temperature or higher; and a display unit that outputs the alarm information.

13 . The cooking apparatus according to claim 1 , further comprising:
a support that supports the cooking vessel, wherein a height of the stacked first and second heating units is the same as a height of the support.

14 . The cooking apparatus according to claim 1 , further comprising:
a control unit that determines a cooking time during operation of at least one of the first heating unit and the second heating unit, and controls output of alarm information when the determined cooking time passes a limit time.

15 . A cooking apparatus comprising:
a first heating unit that has a first hole, and generates heat using a first heat source; a second heating unit that is arranged to be stacked on the first heating unit, has a second hole formed in a position corresponding to the first hole, and generates heat for reinforcing the heat generated by the first heating unit while generating heat using a second heat source; a temperature detection unit that is arranged to protrude to the outside of the second hole while being arranged in the first hole of the first heating unit and the second hole of the second heating unit, and detects a temperature of a cooking vessel when the cooking vessel is brought into contact with the temperature detection unit; an input unit that receives an operation command of the first heating unit; and a control unit that controls an operation of the second heating unit when the operation command of the first heating unit is received.

16 . The cooking apparatus according to claim 15 , wherein the temperature detection unit includes
a sensing portion that protrudes to the outside of the second hole and detects the temperature of the cooking vessel, a guidance portion that is connected to the sensing portion, receives a signal line of the sensing portion and a communication line and a power line of the second heating unit, and is movably arranged inside the first hole and the second hole, and an elastic member that elastically supports the guidance portion.

17 . The cooking apparatus according to claim 15 , wherein the second heating unit includes
a heat generation unit that generates heat using electrical energy, a housing that receives the heat generation unit, an insulation portion that is arranged between the first heating unit and a lower surface of the housing and prevents emission of heat generated by the heat generation unit, and a panel that is arranged adjacent to an upper surface of the housing, and wherein the insulation portion, the housing, and the panel are arranged to be stacked on top of one another and respectively have the second hole.
