-
FIG. 1 is a perspective view illustrating a cooking appliance according to a first embodiment. - Referring to
FIG. 1 , acooking appliance 1 according to the current embodiment includes amain body 10 provided with acooking compartment 120, and adoor 20 for opening and closing thecooking compartment 120. - In detail, a
top surface 110 of themain body 10 is provided with a first cooking part. The first cooking part includes one ormore heating parts 111 disposed on thetop surface 110 of themain body 10. Theheating parts 111 may use at least one of electricity and fuel gas to heat food disposed over theheating parts 111. For example, theheating parts 111 may heat food by using a heater for generating heat with electricity applied, may use an electromagnetic field generated by applied electricity to generate induced current in a container in which food is accommodated, may directly heat food with flame generated by burning fuel gas, or may transfer heat generated by burning fuel gas to food through a heat transferring member. - A
back guard 113 is disposed behind the first cooking part. Theback guard 113 may minimize direct heat transfer from the first cooking part to furniture or a wall disposed behind thecooking appliance 1. - A second cooking part is disposed under the first cooking part. The second cooking part includes a
cavity 121 forming a space that accommodates food therein. That is, the inside of thecavity 121 functions as thecooking compartment 120 to accommodate and cook food. Aheating plate 13 is disposed in thecavity 121. Food may be placed on the top surface of theheating plate 13. Theheating plate 13 may partition the inner space of thecavity 121 according to a position in thecavity 121. - Both side surfaces of the
cavity 121 are provided with forming parts to limit a vertical movement of theheating plate 13, that is, to support and fix theheating plate 13. The forming parts correspond to each other at the same height on both the side surfaces of thecavity 121. A height of the forming part on the side surface of thecavity 121 is equal to or greater than a thickness of theheating plate 13. The forming parts are long in the back and forth direction of thecooking appliance 1 such that theheating plate 13 is removably coupled to thecavity 121. That is, while theheating plate 13 is removed from or coupled to thecavity 121, theheating plate 13 is slid in the back and forth direction by the forming parts. - The second cooking part is provided with heating parts for heating food accommodated in the
cooking compartment 120. The heating parts may include at least one of a heater using electricity, and a burner for burning fuel gas. At least one 14 of the heating parts is disposed at the upper side of thecavity 121. - However, the heating parts may be disposed at various sides of the
cavity 121 including the lower and rear sides of thecavity 121 as well as the upper side of thecavity 121. When food is directly heated by radiant heat from the heating part, the heating part may be disposed at least one of the upper and lower sides of thecavity 121. When food is indirectly heated by air heated by the heating part in thecooking compartment 120, the heating part may be disposed on the rear side of thecavity 121. In this case, a fan may be provided to move the air in thecooking compartment 120 through convection, thereby further improving cooking efficiency. - In the current embodiment, the
heating plate 13 constitutes the heating part. Theheating plate 13 includes aheater section 133 for emitting heat, and aheat accumulation section 132 for storing and emitting heat generated by theheater section 133. Theheating plate 13 will be described later in more detail. - The top surface of the
cavity 121 is rounded to be convex upward. - In detail, the top surface of the
cavity 121 is rounded such that the center thereof is highest and both side ends thereof are lowest. Theheating part 14 is spaced a constant distance from the top surface of thecavity 121. That is, theheating part 14 conforms with the top surface of thecavity 121. A reflective part is disposed at the upper side of theheating part 14 to reflect heat from theheating part 14 to thecooking compartment 120. The reflective part is also spaced a constant distance from the top surface of thecavity 121, that is, conforms with the top surface of thecavity 121. In this case, when being viewed from a front view, the top surface of thecavity 121 may have one of various shapes such as an arc, an oval, and a parabola. - When the top surface of the
cavity 121 has an arc, that is, a shape spaced a constant distance from an imaginary line extending in the back-and-forth direction in thecavity 121, heat emitted from the heating part may be reflected from the reflective part, and be collected to the imaginary line. - A side of the
main body 10 is provided with aninput part 161 to which signals for controlling the first and second cooking parts are input, and anoutput part 165 from which information about operation states of the first and second cooking parts, and information needed for using the first and second cooking parts are output. Theinput part 161 may be disposed on the front surface of thecooking appliance 1, or near the front surface, so that a user can easily approach theinput part 161. Theoutput part 165 may be disposed on the front surface of theback guard 113 or the front surface of thecooking appliance 1, so that a user can easily recognize theoutput part 165. - Electric parts are installed on a side of the
main body 10 to operate the first and second cooking parts. Since the electric parts are sensitive to heat, the electric parts may be disposed in a portion of the first and second cooking parts where the amount of transferred heat is small. For example, the electric parts may be provided to theback guard 113. This is because theback guard 113 has a lower temperature than the other portions of thecooking appliance 1. - The
door 20 is rotatably disposed at the front side of themain body 10. Thedoor 20 may rotate downward about the lower end thereof, rotate upward about the upper end thereof, or rotate to a side end or both side ends thereof about the side end or both the side ends. Thus, a rotation direction of thedoor 20 may vary. When the weight of thedoor 20 is considered, thedoor 20 may be designed to rotate downward about the lower end thereof. - The
door 20 may be provided with a seeing throughwindow 21 to check a state of food cooked in thecavity 121. - The front surface of the
main body 10 and the rear surface of thedoor 20 may be provided with brick patterns to imitate a brick structure. The brick patterns may be formed by partially recessing or protruding the front surface of themain body 10 and the rear surface of thedoor 20. The brick patterns provide aesthetic effect and a delicate appearance such as a fire place or an old-fashioned oven. - The heating plate will now be described in more detail with reference to the accompanying drawings.
-
FIG. 2 is a cross-sectional view illustrating the heating plate of the cooking appliance according to the first embodiment.FIG. 3 is a perspective view illustrating a state in which the heating plate of the cooking appliance is removed according to the first embodiment. - Referring to
FIGS. 2 and 3 , theheating plate 13 includes theheater section 133 for generating heat, and theheat accumulation section 132 adjacent to theheater section 133. In detail, theheater section 133 includes aheater 134 for emitting heat and a heater receiving part receiving theheater 134. The heater receiving part has a flat plate shape with an inner space, and constitutes an outer surface of theheater section 133. Theheater 134 is received in the inner space of the heater receiving part. Anend 135 of theheater 134 passes through a side portion of the heater receiving part, and is exposed out of the heater receiving part. Theend 135 of theheater 134 is an electrode part (also denoted by 135) connected to a power source to supply power to theheater 134. - The
heat accumulation section 132 is adjacent to a surface of theheater section 133, and has a flat plate shape having the same area as that of theheater section 133. The thickness of theheater section 133 and theheat accumulation section 132 may be varied according to purpose of cooking. Theheat accumulation section 132 absorbs heat emitted from theheater section 133 to store and emit the heat. Theheat accumulation section 132 is formed of a material having high specific heat, such as a stone-based material, to increase the amount of stored heat. - The
heater section 133 and theheat accumulation section 132 are provided with a coupling part to removably couple theheater section 133 and theheat accumulation section 132 to each other. The coupling part includes a plurality ofcoupling protrusions 136 provided to theheater section 133, and a plurality of coupling recesses 137 provided to theheat accumulation section 132. The coupling protrusions 136 gradually increase in width in a protruding direction from a surface of theheater section 133. The coupling recesses 137 are disposed in a surface of theheat accumulation section 132, and have a shape corresponding to thecoupling protrusions 136. The coupling protrusions 136 and the coupling recesses 137 are elongated from one end of theheater section 133 and theheat accumulation section 132 to another end thereof. - Thus, the
heater section 133 and theheat accumulation section 132 are coupled to and decoupled from each other through sliding. For example, to couple theheater section 133 and theheat accumulation section 132 to each other, first ends of thecoupling protrusions 136 of theheater section 133 may be inserted in second ends of the coupling recesses 137 of theheat accumulation section 132, and then, theheater section 133 and theheat accumulation section 132 may be slid against each other until the first ends of thecoupling protrusions 136 arrive at first ends of the coupling recesses 137. After the coupling, theheater section 133 and theheat accumulation section 132 are locked to each other, and thus, relative motion between theheater section 133 and theheat accumulation section 132 is limited except for the longitudinal direction of thecoupling protrusions 136 and the coupling recesses 137. Theheater section 133 and theheat accumulation section 132 may be removed from each other in a reverse order of the coupling of theheater section 133 and theheat accumulation section 132. - Thus, the
heater section 133 and theheat accumulation section 132 may be independently installed on thecavity 121. In more detail, only theheater section 133 may be installed on thecavity 121 by removing theheat accumulation section 132 from theheater section 133. Alternatively, only theheat accumulation section 132 may be installed on thecavity 121 by removing theheater section 133 from theheat accumulation section 132. - Although the
electrode part 135 straightly extends rearward from theheater section 133 in the current embodiment, theelectrode part 135 may be bent in a Z shape from theheater section 133 such that the end of theelectrode part 135 is disposed at the center of theheating plate 13 in a thick direction thereof. In this case, theheating plate 13 may be upside down on thecavity 121 such that theheater section 133 and theheat accumulation section 132 change the positions thereof with each other. That is, theheating plate 13 may have two directivities. - A process in which the heater section is connected to and disconnected from the power source will now be described with reference to the accompanying drawings.
-
FIG. 4 is a cross-sectional view illustrating a state in which the heater section is disconnected from the power source according to the first embodiment.FIG. 5 is a cross-sectional view illustrating a state in which the heater section is connected to the power source according to the first embodiment. - Referring to
FIGS. 4 and 5 , thecooking appliance 1 includes a power connecting part for connecting the heater to the power source. The power connecting part includes theelectrode part 135, anelectrode hole 122 disposed in thecavity 121, an opening/closing part for opening and closing theelectrode hole 122, and apower source part 125 disposed behind thecavity 121. - In detail, the
heater section 133 is installed on thecavity 121, and theelectrode hole 122 is disposed in thecavity 121 to correspond to theelectrode part 135, so that theelectrode part 135 can be selectively inserted in theelectrode hole 122. When theelectrode part 135 is connected to the power source, electric current is prevented from flowing to thecavity 121. To this end, theelectrode hole 122 has a greater diameter than that of theelectrode part 135. - The opening/closing part is disposed in front of the
electrode hole 122 to selectively open and close theelectrode hole 122. In more detail, the opening/closing part includes a plurality of closingmembers 123 for closing theelectrode hole 122, and a plurality ofelastic members 124 for pressing the closingmembers 123 in certain directions to close theelectrode hole 122. The closingmembers 123 are disposed at the upper and lower sides of theelectrode hole 122, respectively. Ends of the closingmembers 123, which face each other, are provided with slopes that collide with theelectrode part 135 when theheating plate 13 is installed on thecavity 121. - The closing
members 123 are disposed on a forming part formed by recessing a portion of the rear surface of thecavity 121 rearward. The closingmembers 123 can vertically slide along the forming part. One of theelastic members 124 is disposed on the upper portion of the closingmember 123 disposed over theelectrode hole 122, and presses the closingmember 123 downward. The other of theelastic members 124 is disposed on the lower portion of the closingmember 123 disposed under theelectrode hole 122, and presses the closingmember 123 upward. Thepower source part 125 is fixed to arear plate 126 disposed behind thecavity 121. Thepower source part 125 is open forward to receive theelectrode part 135. Thepower source part 125 is connected through a wire to the power source for supplying electricity. - An insulating
member 128 is disposed between the rear surface of thecavity 121 and therear plate 126 to thermally insulate thecavity 121 from the outside of thecooking appliance 1. The insulatingmember 128 is disposed out of a region overlapping thepower source part 125 in the back-and-forth direction. Thus, while theelectrode part 135 is coupled to thepower source part 125, the insulatingmember 128 may guide theelectrode part 135 to thepower source part 125. - A process of connecting the
heater 134 to the power source, that is, a process of connecting theelectrode part 135 to thepower source part 125 will now be described. First, when theheating plate 13 slides rearward to be installed on thecavity 121, theelectrode part 135 also moves rearward. When theelectrode part 135 contacts the slopes of the closingmembers 123, interference therebetween moves the closingmembers 123 upward and downward to open theelectrode hole 122. On the contrary, while theheating plate 13 is removed from thecavity 121, theheater 134 is removed from the power source. - Structures for installing the heating plate on the cavity will now be described with reference to the accompanying drawings.
-
FIG. 6 is a cross-sectional view illustrating a state in which the heating plate partitions the cooking compartment according to the first embodiment.FIG. 7 is a cross-sectional view illustrating the heating plate partitions used as a lower heater according to the first embodiment.FIG. 8 is a cross-sectional view illustrating a structure in which a portion of the cooking compartment functions as a heater using accumulated heat, according to the first embodiment. - Referring to
FIGS. 6 to 8 , a structure for installing theheating plate 13 on thecooking compartment 120 may be varied according to its purpose. - The inner surface of the
cavity 121 is provided with forming parts on which theheating plate 13 is installed. A part of formingparts 129 positions theheating plate 13 to partition thecavity 121 into two spaces, and the other part thereof positions theheating plate 13 on the bottom surface of thecavity 121. - When the
heating plate 13 is positioned to partition thecavity 121 into two spaces, or is positioned on the bottom surface of thecavity 121, a portion of the rear surface of thecavity 121, which overlaps theelectrode part 135 of theheating plate 13 in the back-and-forth direction, is provided with thepower source part 125, theelectrode hole 122, and the opening/closing part to which theelectrode part 135 is connected. - Thus, the
heating plate 13 is selectively disposed on at least two positions. When theheating plate 13 is positioned to partition thecavity 121 into two spaces, theheater section 133 and theheat accumulation section 132 of theheating plate 13 are exposed to the two spaces, respectively. That is, one of the two spaces may be directly heated by theheater section 133, and the other thereof may be indirectly heated by theheat accumulation section 132. In more detail, since one of the two spaces, which is heated by theheater section 133, directly receives heat from theheater section 133, temperature increase thereof is large. Since the other of the two spaces, which is heated by theheat accumulation section 132, indirectly receives heat from theheater section 133 after being accumulated in theheat accumulation section 132, temperature increase thereof is small. Thus, food can be quickly heated and cooked in the space exposed directly to theheater section 133, and food can be gradually heated and cooked in the space exposed to theheat accumulation section 132. The gradually heating and cooking of food corresponds to a brick oven cooking method. The brick oven cooking method is at least one of a method of collecting heat from a heating source disposed along the rounded top surface of thecavity 121, and a method of gradually transferring heat to food through theheat accumulation section 132 without directly transferring heat from theheater section 133 to the food. For example, food such as bread is adapted for the brick oven cooking method. If bread is quickly heated, the amount of moisture evaporated from the bread is increased, and the bread may be burned. Thus, bread needs a gradual heating method. Since theheating plate 13 can be installed on thecavity 121, regardless of directions of theheater section 133 and theheat accumulation section 132, any one of the two spaces of thecavity 121 partitioned by theheating plate 13 can be directly heated or indirectly heated. As illustrated inFIG. 6 , theheating plate 13 is installed on thecavity 121 to partition thecavity 121 into two spaces. That is, referring toFIG. 6 , an indirect-heat cooking process may be performed in the upper one of two spaces separated by theheating plate 13, and a direct-heat cooking process may be performed in the lower one thereof. When theheating plate 13 is upside down, a direct-heat cooking process may be performed in the upper space, and an indirect-heat cooking process may be performed in the lower space. - The
heating plate 13 may be disposed on the bottom surface of thecavity 121 as illustrated inFIG. 7 . Also in this case, theheating plate 13 can be installed on thecavity 121, regardless of directions of theheater section 133 and theheat accumulation section 132. That is, theheater section 133 may be directed upward, or theheat accumulation section 132 may be directed upward. When theheater section 133 may be directed upward, heat is directly transferred from theheater section 133 to the inner space of thecavity 121, so that food can be quickly heated and cooked in thecavity 121. When theheat accumulation section 132 is directed upward, heat generated from theheater section 133 is accumulated in theheat accumulation section 132, and then, is indirectly transferred to the inner space of thecavity 121 through theheat accumulation section 132, so that food can be gradually heated and cooked in thecavity 121. - When the
heating plate 13 is positioned to partition thecavity 121 into two spaces, one ormore heating plates 15 may be disposed on one or more side surfaces of one of the two spaces, to thereby more efficiently perform a brick oven cooking process. In this case, theheating plate 13 partitioning thecavity 121 may be referred to as a horizontal plate, and theheating plates 15 may be referred to as vertical plates. In detail, like thehorizontal plate 13, thevertical plates 15 may include theheater section 133 and theheat accumulation section 132, which are selectively removed. A hook provided to thevertical plate 15 may hook a rack provided to the inner surface of thecavity 121, to thereby install thevertical plate 15 on thecavity 121. However, a structure for installing thevertical plate 15 on thecavity 121 is not limited thereto. In addition, like theheating plate 13, thevertical plates 15 may be installed on thecavity 121, regardless of directions of theheater section 133 and theheat accumulation section 132. - The
horizontal plate 13 and thevertical plates 15 are installed on thecavity 121 as illustrated inFIG. 8 . In this case, thehorizontal plate 13 and thevertical plates 15 are disposed in the upper one of the two spaces separated by thehorizontal plate 13, and theheat accumulation sections 132 are exposed to the upper space. Thus, food accommodated in the upper space can be gradually heated and cooked by thehorizontal plate 13 and thevertical plates 15 at the same time. Furthermore, heat emitted from theheating part 14 disposed on the top of thecavity 121 is collected in the food, to thereby improve cooking efficiency. That is, thevertical plates 15 improve efficiency of the brick oven cooking process. - Moreover, when the
heat accumulation section 132 is additionally disposed under theheating part 14 to accumulate and emit heat generated from theheating part 14, the food accommodated in the upper space separated by thehorizontal plate 13 is heated in all directions through theheat accumulation sections 132, thereby maximizing the efficiency of the brick oven cooking process. - A method of controlling the cooking appliance will now be described with reference to the accompanying drawing.
-
FIG. 9 is a block diagram illustrating flow of control signals within the cooking appliance according to the first embodiment. - Referring to
FIG. 9 , thecooking appliance 1 includes: theinput part 161 through which various signals for controlling thecooking appliance 1 are input; aninstallation sensing part 162 for sensing installation of thehorizontal plate 13 and thevertical plates 15; acontrol part 163 receiving a signal input to theinput part 161, and a signal sensed by theinstallation sensing part 162; amemory part 164 storing various types of information for operating thecooking appliance 1; theoutput part 165 outputting various signals recognized by a user; and acooking operation part 166 for cooking food. - In detail, the
input part 161 through which various signals for controlling thecooking appliance 1 are input, may be provided with various structures such as a button or a dial. Theinstallation sensing part 162 senses whether at least one of thehorizontal plate 13 and thevertical plates 15 is installed on thecavity 121. To this end, theinstallation sensing part 162 may sense an approach of thehorizontal plate 13 and thevertical plates 15, or sense whether power is supplied to thehorizontal plate 13 and thevertical plates 15, but is not limited thereto. - The
memory part 164 may store various types of information for cooking food, such as a set cooking condition. Theoutput part 165 outputs an audio signal such as a sound and a voice, or a visual signal such as a character and a color, so that a user can perceive various types of information. Thecooking operation part 166 substantially cooks food, and may include, for example, a heater, a burner, and a fan. - The
cooking appliance 1 may be operated in a brick oven cooking mode. In the brick oven cooking mode, food is cooked in the state where thehorizontal plate 13 and thevertical plates 15 are all installed in thecavity 121. When at least one of thehorizontal plate 13 and thevertical plates 15 is not installed, a signal for operating thecooking appliance 1 in the brick oven cooking mode may be input. - Thus, when a signal for the brick oven cooking mode is input through the
input part 161, theinstallation sensing part 162 senses whether thehorizontal plate 13 and thevertical plates 15 are installed. When theinstallation sensing part 162 senses that thehorizontal plate 13 and thevertical plates 15 are all installed, thecontrol part 163 operates thecooking operation part 166 in a normal mode. - However, when the
installation sensing part 162 senses that at least one of thehorizontal plate 13 and thevertical plates 15 is not installed, thecontrol part 163 outputs, through theoutput part 165, a signal denoting that at least one of thehorizontal plate 13 and thevertical plates 15 is not installed. Accordingly, a user recognizes that at least one of thehorizontal plate 13 and thevertical plates 15 is not installed, and may install the one of thehorizontal plate 13 and thevertical plates 15. To normally perform the brick oven cooking mode, theheat accumulation section 132 of thehorizontal plate 13 is disposed over theheater section 133. Thus, it may be sensed whether thehorizontal plate 13 is installed in a normal position. If thehorizontal plate 13 is upside down, it may be notified to a user that thehorizontal plate 13 is upside down. - In detail, the
power source part 125 connected to thehorizontal plate 13 may sense whether thehorizontal plate 13 is installed in the normal position. For example, thepower source part 125 and the opening/closing part may be provided in duplicate to portions of the rear surface of thecavity 121 corresponding to thehorizontal plate 13 installed on thecavity 121. Accordingly, if thehorizontal plate 13 is upside down, theelectrode part 135 is not connected to a correct one of thepower source parts 125 with respect to the normal position, and is connected to a false one of thepower source parts 125. That is, it can be sensed whether thehorizontal plate 13 is installed in the normal position by identifying thepower source part 125 connected to theelectrode part 135. However, a method of sensing whether thehorizontal plate 13 is installed in the normal position is not limited thereto. - When it is sensed that the
horizontal plate 13 is installed in the normal position, thecontrol part 163 controls thecooking operation part 166 to perform the brick oven cooking mode. - However, unless the
horizontal plate 13 is installed in the normal position, thecontrol part 163 controls theoutput part 165 to output an alarm signal denoting that thehorizontal plate 13 is incorrectly installed. Thus, a user perceiving the alarm signal output by theoutput part 165 may take an action for installing thehorizontal plate 13 in the normal position. - When the brick oven cooking mode is performed, the
horizontal plate 13 is disposed in a position for partitioning thecavity 121. However, when thehorizontal plate 13 is installed on the bottom surface of thecavity 121, a signal for performing the brick oven cooking mode may be input. Also in this case, the above-described method may be used to notify a user that thehorizontal plate 13 is incorrectly installed. - A cooking appliance according to a second embodiment will now be described with reference to the accompanying drawings. The current embodiment is different from the first embodiment in a power connecting part and a coupling structure of a heater section and a heat accumulation section.

FIG. 10 is a perspective view illustrating a removal of a heating plate of a cooking appliance according to the second embodiment.FIG. 11 is a cross-sectional view illustrating a heater section removed from a power source according to the second embodiment.FIG. 12 is a cross-sectional view illustrating a state in which the heater section ofFIG. 11 is connected to the power source. - Referring to
FIGS. 10 to 12 , aheater section 233 of aheating plate 23 is provided withrail parts 236 to receive aheat accumulation section 232. In detail, therail parts 236 extend in an L shape from both ends of theheater section 233. The distance between therail parts 236 provided to both the ends of theheater section 233 corresponds to the width of theheat accumulation section 232. Thus, theheat accumulation section 232 may be inserted between therail parts 236. Since therail parts 236 are elongated in a certain direction along both the ends of theheater section 233, a first end of theheat accumulation section 232 received in second ends of therail parts 236 slides until arriving at first ends of therail parts 236, to thereby couple theheat accumulation section 232 to theheater section 233. - A power connecting part for connecting the
heater section 233 to a power source includes anelectrode hole 222 disposed in the rear portion of acavity 221, and a closingmember 123 selectively closing theelectrode hole 222. In detail, when theheater section 233 is installed on thecavity 221, theelectrode hole 222 is disposed in a region of the rear portion of thecavity 221 to correspond to anelectrode part 235 of theheater section 233. When theheater section 233 is connected to the power source, electric current is prevented from flowing to thecavity 221. To this end, theelectrode hole 222 has a greater diameter than that of theelectrode part 235. - The closing
member 223 vertically moves at theelectrode hole 222 to open and close theelectrode hole 222. A support is disposed under the closingmember 223 to support the closingmember 223 when the closingmember 223 closes theelectrode hole 222. A portion defining the lower end of theelectrode hole 222 is recessed forward to form the support. - The
electrode part 235 is coupled to apower source part 225 by moving the closingmember 223 upward, that is, opening theelectrode hole 222, then, moving theheating plate 23 rearward to install theheating plate 23 on thecavity 221. - A cooking appliance according to a third embodiment will now be described with reference to the accompanying drawings. The current embodiment is different from the first embodiment in a power connecting part.
FIG. 13 is a cross-sectional view illustrating a heater section disconnected from a power source according to the third embodiment.FIG. 14 is a cross-sectional view illustrating a state in which the heater section ofFIG. 13 is connected to the power source. - Referring to
FIGS. 13 and 14 , a power connecting part includes a closingmember 323 rotatably installed on the rear portion of acavity 321. In detail, aheater section 333 is installed on thecavity 321, and anelectrode hole 322 is disposed in a region of the rear portion of thecavity 121 to correspond to anelectrode part 335. When theheater section 333 is connected to a power source, electric current is prevented from flowing to thecavity 321. To this end, theelectrode hole 322 has a greater diameter than that of theelectrode part 335. - The closing
member 323 rotates rearward from the rear portion of thecavity 321 to selectively close theelectrode hole 322. An elastic member is disposed at an end of the closingmember 323 to press the closingmember 323, so that the closingmember 323 can continually close theelectrode hole 322. - While the
heater section 333 moves rearward, and is installed on thecavity 321, theelectrode part 335 pushes the closingmember 323 rearward to open theelectrode hole 322, to thereby couple theelectrode part 335 to a power source part. - According to the above-described embodiments, food can be more intensively heated in the cooking compartment, thus improving the cooking efficiency.
- Heat generated from the heater is accumulated in the heat accumulation section, and then, is transferred to food. Accordingly, food can be heated with accumulated heat, that is, be gradually heated.
- Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
