Hereinafter, an embodiment of a cooking appliance according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of a first embodiment of a cooking appliance according to the present invention.

Referring to FIG. 1, the cooking apparatus 1 includes a main body 10 provided with a cooking chamber 120 and a door 20 for opening and closing the cooking chamber 120.

In detail, the upper surface 110 of the main body 10 is provided with a first cooking unit. In addition, the first cooking unit includes at least one heating unit 111 disposed on the upper surface 110 of the main body 10. The heating unit 111 may heat the food positioned above the heating unit 111 using at least one of electricity and gas. For example, when electricity is applied, the food is heated using a heater that emits heat, or induction heating is used to generate an induction current in a container containing the food using an electromagnetic field generated when electricity is applied. Various methods of heating the food are possible, such as heating the food directly using a flame when the gas is burned, or heating the combustion heat of the gas through the heat transfer member in a conductive heating manner.

The back guard 113 is provided at the rear of the first cooking unit. The back guard 113 may minimize a phenomenon in which heat generated by the first cooking unit is directly transmitted to a furniture or a wall located at the rear of the cooking apparatus 1.

The second cooking unit is provided below the first cooking unit. The second cooking unit includes a cavity 121 that forms a space for accommodating food therein. That is, the inside of the cavity 121 corresponds to the cooking chamber 120 for receiving and cooking food. In addition, a heating plate 13 is provided inside the cavity 121. Food may be seated on the upper surface of the heating plate 13. In addition, the heating plate 13 may partition the inside of the cavity 121 according to the position of the inside of the cavity 121.

In addition, on both sides of the cavity 121, a forming part for limiting the vertical movement of the heating plate 13, that is, for supporting and fixing the heating plate 13 is formed. The forming part is located on one side and the other side of the cavity 121 to correspond to the same height. And, on one side of the cavity 121, the interval between the forming portion corresponds to the length or more corresponding to the thickness of the heating plate (13). In addition, the forming part is formed long in the front and rear so that the heating plate 13 is detachable to the cavity 121. That is, in the process of detaching the heating plate 13 from the cavity 121, the heating plate 13 may be guided to slide back and forth by the forming unit.

The second cooking unit is provided with a heating unit for heating the food accommodated in the cooking chamber 120. The heating unit may include at least one of a heater using electricity and a burner for burning a gas. At least one of the heating parts 14 is installed above the cavity 121.

However, the heating unit may be further installed at other positions such as the lower side and the rear side as well as the upper side of the cavity 121. However, when the food is directly heated by radiant heat of the heating unit, the heating unit is generally located at at least one of the upper side and the lower side of the cavity 121, and the cooking chamber heated by the heating unit ( In the case of heating the food indirectly through the air of 120, the heating unit is generally located at the rear of the cavity 121. However, in the case of an indirect heating method of heating the air of the cooking chamber 120, a fan may be further provided and the cooking efficiency may be further increased when the air of the cooking chamber 120 is convection.

In the present embodiment, the heating plate 13 is also included in the heating unit. The heating plate 13 includes a heater unit 133 that emits heat, and a heat storage unit 132 that stores and releases heat generated by the heater unit 133. A more detailed description of the heating plate 13 will be described later.

Here, the upper surface of the cavity 121 is a shape convexly rounded upward. In detail, the upper surface of the cavity 121 is rounded so that the center portion of the upper surface of the cavity 121 is positioned highest, and the lower end of both sides of the upper surface of the cavity 121 is positioned lowest. In addition, the heating unit 14 is installed on the upper surface of the cavity 121 to be spaced apart by the same interval as the upper surface of the cavity 121. That is, the heating unit 14 is located along the upper surface of the cavity 121. In addition, above the heating unit 14, a reflecting unit for reflecting the heat emitted from the heating unit 14 toward the cooking chamber 120 is provided. In this case, the reflector is also installed to be spaced apart from the upper surface of the cavity 121 by the same interval, that is, located along the upper surface of the cavity 121. In this case, the upper surface of the cavity 121 may have various shapes such as an arc, an ellipse, or a parabola when viewed from the front.

However, when the upper surface of the cavity 121 has a circular arc shape, that is, a shape spaced apart by an equal distance from an imaginary straight line which is placed back and forth inside the cavity 121, the heat emitted from the heating part is reflected. It can be reflected to and concentrated at the point where the virtual straight line is located.

On the other hand, on one side of the main body 10, the input unit 161 for inputting a signal for controlling the operation of the first cooking unit and the second cooking unit, and the operating state and use necessary for the first cooking unit and the second cooking unit An output unit 165 for outputting various kinds of information is provided. The input unit 161 is preferably located at the front or near the front of the cooking appliance 1, which is easily accessible by the user. In addition, the output unit 165 may be located on the front of the back guard 113, which is easy for the user to recognize, or may be located on the front of the cooking appliance 1.

In addition, one side of the main body 10 is equipped with electrical components for the operation of the first cooking unit and the second cooking unit. In general, since the electrical component is heat sensitive, it is preferable to be located at a portion where the amount of heat transfer of the first cooking unit and the second cooking unit is relatively small. For example, the electrical component may be located on the back guard 113. This is because the temperature of the back guard 113 on the cooking appliance 1 is relatively low compared to other portions.

On the other hand, the door 20 is rotatably installed in front of the main body 10. The door 20 is rotated downward based on the lower end of the door 20 in a rotating direction, rotated upward based on the upper end of the door 20, and the door ( 20) can be installed in various ways, such as rotating in one side or both sides based on one side or both ends. However, in consideration of the weight of the door 20, a method of rotating downward based on the lower end of the door 20 is most preferable.

In addition, the door 20 may be provided with a viewing window 21 for checking a cooking state of the food accommodated in the cavity 121.

Meanwhile, a brick pattern is formed on the front surface of the main body 10 and the rear surface of the door 20 in a shape of stacked bricks. The brick pattern may be formed by recessing or protruding a portion of the front surface of the main body 10 and the rear surface of the door 20. Due to the brick pattern, the user can feel aesthetics, and at the same time, there is an advantage in that a soft feeling such as a fireplace or a fireplace can be obtained.

Hereinafter, the heating plate will be described in more detail with reference to the accompanying drawings.

2 is a cross-sectional view of a heating plate of the first embodiment of the cooking appliance according to the present invention, Figure 3 is a perspective view showing a state in which the heating plate of the first embodiment of the cooking appliance according to the present invention is separated.

2 and 3, the heating plate 13 includes a heater unit 133 that generates heat, and a heat storage unit 132 adjacent to the heater unit 133. In detail, the heater unit 133 includes a heater 133 that emits heat and a heater accommodating unit in which the heater is accommodated. The heater accommodating part has a flat plate shape having a space formed therein, and forms an outer surface of the heater part 133. The heater 133 is accommodated in the inner space of the heater accommodating part. In addition, the end 135 of the heater penetrates through one side of the heater accommodating part and is exposed to the outside of the heater accommodating part. An end 135 of the heater corresponds to an electrode unit 135 connected to a power source in order to supply power to the heater.

In addition, the heat storage unit 132 is adjacent to one surface of the heater unit 133 and has a flat shape having the same area as the heater unit 133. However, the thickness of the heater 133 and the heat storage unit 132 may be various values depending on the purpose of cooking. The heat storage unit 132 absorbs heat emitted from the heater unit 133 to store and release the heat. In this case, the heat storage unit 132 is formed of a relatively large heat such as a stone, for example, so that the amount of heat stored more.

In addition, the heater unit 133 and the heat storage unit 132 is provided with a coupling portion that can be detached from each other. The coupling part includes a coupling protrusion 136 provided in the heater unit 133 and a coupling groove 137 provided in the heat storage unit 132. The coupling protrusion 136 is formed in a shape that gradually widens in a direction protruding from one surface of the heater unit 133. In addition, the coupling groove 137 is formed in a shape corresponding to the coupling protrusion 136 on one surface of the heat storage unit 132. At this time, the coupling protrusion 136 and the coupling groove 137 are formed from one end to the other end of the heater unit 133 and the heat storage unit 132 long in one direction, respectively.

Therefore, the heater unit 133 and the heat storage unit 132 may be coupled and separated in a sliding manner. For example, one end of the coupling protrusion 136 of the heater unit 133 is inserted into the other end of the coupling groove 137 of the heat storage unit 132, one end of the coupling protrusion 136 is the coupling The heater unit 133 and the heat storage unit 132 may be coupled in such a manner that the heater unit 133 and the heat storage unit 132 slide with each other until they are positioned at one end of the groove 137. In the state in which the heater unit 133 and the heat storage unit 132 are coupled, the length of the coupling protrusion 136 and the coupling groove 137 is extended due to the interference of the coupling protrusion 136 and the coupling groove 137. Except for the direction, the relative movement of the heater unit 133 and the heat storage unit 132 is limited. In addition, the operation of separating the heater unit 133 and the heat storage unit 132 may be performed in a reverse order to the method of combining the heater unit 133 and the heat storage unit 132.

Therefore, the heater unit 133 and the heat storage unit 132 may be independently mounted to the cavity 121. In more detail, when only the heater unit 133 is to be used, the heat storage unit 132 may be separated from the heater unit 133, and only the heater unit 133 may be mounted in the cavity 121. . In addition, when only the heat storage unit 132 is to be used, the heater unit 133 may be separated from the heat storage unit 132, and only the heat storage unit 132 may be mounted in the cavity 121.

However, in the present embodiment, although the electrode portion 135 of the heater extends immediately after the heater portion 133, the electrode portion 135 of the heater is 'Z' from the heater portion 133. When the end position of the electrode portion 135 is bent into a shape and is positioned at the center of the thickness direction of the heating plate 13 to which the heater unit 133 and the heat storage unit 132 are coupled, the heater unit The heating plate 13 may be inverted so that the positions of the 133 and the heat storage unit 132 are opposite to each other. That is, in this case, there is an advantage that the heating plate 13 can be selectively used in two directions.

Hereinafter, the state in which the heater unit is connected to and disconnected from the power source will be described in detail with reference to the accompanying drawings.

4 is a view showing a state in which the heater unit of the first embodiment of the cooking appliance according to the present invention is separated from the power source, and FIG. 5 is a view illustrating a state in which the heater unit of the first embodiment of the cooking appliance according to the present invention is connected to the power source.

4 and 5, the cooking appliance 1 includes a power connection unit for connecting the heater to a power source. The power connection part includes an electrode part 135, an electrode hole 122 formed in the cavity 121, an opening and closing part that opens and closes the electrode hole 122, and a power supply part provided behind the cavity 121. And 125.

In detail, in a state in which the heater unit 133 is mounted in the cavity 121, an electrode hole for selectively inserting the electrode unit 135 into the cavity 121 corresponding to the electrode unit 135. 122 is formed. In the state in which the electrode unit 135 is connected to a power source, the electrode hole 122 is formed to be larger than the diameter of the electrode unit 135 to prevent a short circuit of electricity to the cavity 121.

The opening and closing part selectively opens and closes the electrode hole 122 in front of the electrode hole 122. More specifically, the opening and closing portion, the shielding member 123 for shielding the electrode hole 122, and the elastic member 124 for pressing the shielding member 123 in the direction to shield the electrode hole 122 It includes. The shielding members 123 are provided one above and one below with respect to the electrode hole 122. At the end portions adjacent to each other in the two shielding members 123, an inclined surface for interfering with the electrode unit 135 is formed in the process of mounting the heating plate 13 to the cavity 121.

The shielding member 123 is installed in a forming part in which a part of the rear surface of the cavity 121 is formed rearward. The shielding member 123 is slidable up and down along the forming part. In addition, an upper portion of the shielding member 123 positioned above the electrode hole 122 is provided with an elastic member 124 that presses the shielding member 123 downward, and below the electrode hole 122. Below the shielding member 123 is provided is provided with an elastic member 124 for pressing the shielding member 123 upwards.

The power supply 125 is fixed to the rear plate 126 provided at the rear of the cavity 121. The power supply 125 is installed toward the front to allow the electrode 135 to be inserted. The power supply 125 is connected to a power supply for supplying electricity.

In addition, an insulation material 128 is provided between the rear surface of the cavity 121 and the rear plate 126 to insulate the cavity 121 from the outside of the cooking appliance 1. At this time, the heat insulator 128 is provided at a portion except for a portion overlapping with the power supply 125 in the front and rear. Therefore, in the process of coupling the electrode unit 135 to the power supply unit 125, the electrode unit 135 may be guided toward the power supply unit 125 by the heat insulating material 128.

Meanwhile, a process in which the heater 134 is connected to a power source, that is, a process in which the electrode unit 135 is connected to the power source 125, is described. First, the heating plate 13 is connected to the cavity 121. The electrode portion 135 is also moved rearward when sliding backward to be mounted. When the electrode part 135 comes in contact with the inclined surface of the shielding member 123, the shielding member 123 moves in the vertical direction by the interference of the electrode part 135 and the inclined surface, and the electrode The hole 122 is opened. On the contrary, in the process of separating the heating plate 13 from the cavity 121, the heater 134 is separated from the power source.

Hereinafter, a state in which the heating plate is mounted in the cavity in various ways will be described in detail with reference to the accompanying drawings.

6 is a view showing the heating plate of the first embodiment of the cooking apparatus according to the present invention partitioned the cooking chamber, Figure 7 is a view of the heating plate of the first embodiment of the cooking apparatus according to the present invention used as a lower heater 8 is a view showing a portion of the cooking chamber used in the heating method using the heat storage in the first embodiment of the cooking appliance according to the present invention.

6 to 8, the heating plate 13 performs various functions depending on the manner in which the heating plate 13 is mounted in the cooking chamber 120.

First, a plurality of forming parts for mounting the heating plate 13 are formed on the inner surface of the cavity 121. A forming unit 129 for the heating plate 13 to be partitioned to the cavity 121 into two spaces, and a forming unit for the heating plate 13 to be located on the bottom surface of the cavity 121 Section 129.

In addition, when the heating plate 13 is located to partition the cavity 121 into two spaces or is located on the bottom surface of the cavity 121, the electrode portion 135 of the heating plate 13 is disposed. The power supply 125, the electrode hole 122, and the opening / closing part for connecting the electrode part 135 are formed on the rear surface of the cavity 121 overlapping with the front and rear sides.

Thus, the heating plate 13 can be selectively mounted in at least two positions. When the heating plate 13 is positioned to partition the cavity 121, the heater unit 133 and the heat storage unit 132 of the heating plate 13 are exposed to each of the two partitioned spaces one by one. . That is, any one of the two divided spaces may be directly heated by the heater unit 133, and the other one may be indirectly heated by the heat storage unit 132. More precisely, the space heated by the heater unit 133 of the two spaces receives the heat generated by the heater unit 133 directly, so that the temperature rise due to heating is relatively large, and the heat storage unit ( In the space heated by 132, the heat generated by the heater 133 is stored in the heat storage unit 132 and indirectly transmitted through the heat storage unit 132, so that the temperature rise due to heating is relatively small. do. Therefore, the space directly exposed to the heater unit 133 of the two spaces can be quickly heated and cooked, and the space exposed to the heat storage unit 132 can be gradually heated and cooked.

Here, the gradual heating and cooking method corresponds to a kind of brick oven cooking method. The brick oven cooking method is a round paper, where a heating source is located along the upper surface of the cavity 121 so that heat generated from the heating source can be concentrated and heat generated from the heater unit 133 is directly cooked. It means at least one of being gradually transmitted through the heat storage unit 132 rather than being transmitted to. Suitable foods to be cooked by the brick oven cooking method may be various ones such as bread, for example. In the case of bread, when heated rapidly, the amount of moisture evaporates and is easy to burn.

In addition, since the heating plate 13 can be mounted to the cavity 121 regardless of the direction in which the heater unit 133 and the heat storage unit 132 face, the heating plate 13 is divided by the heating plate 13 as necessary. It is possible to selectively heat either one of the two spaces of the cavity 121 to be directly or indirectly heated. The heating plate 13 is mounted on the cavity 121 so as to partition the cavity 121 into two spaces as shown in FIG. 6. That is, in the state shown in Figure 6, the upper space of the two spaces partitioned by the heating plate 13 is made of indirect heating cooking and the lower space may be made of direct heating cooking, the heating When the up and down direction of the plate 13 is mounted in an inverted state, the upper space may be cooked by a direct heating method, and the lower space may be cooked by an indirect heating method.

In addition, the heating plate 13 may be located on the bottom surface of the cavity 121. The heating plate 13 is located on the bottom surface of the cavity 121 is shown in FIG. Even in this case, the heating plate 13 can be mounted to the cavity 121 regardless of the direction in which the heater 133 and the heat storage unit 132 face. That is, the heater 133 may face upward, and the heat storage unit 132 may face upward. When the heater unit 133 is directed upward, heat generated in the heater unit 133 is transferred directly into the cavity 121, so that rapid heating and cooking is possible in the cavity 121. When the heat storage unit 132 faces upward, heat generated from the heater unit 133 is stored in the heat storage unit 132 and indirectly into the cavity 121 through the heat storage unit 132. The transmission allows for gradual heating and cooking.

On the other hand, in the cavity 121, in order to cook the brick oven more smoothly, when the heating plate 13 is located to partition the inside of the cavity 121 into two spaces, either side of any one of the two spaces At least one heating plate 15 corresponding to may be further mounted. Here, the heating plate 13 partitioning the inside of the cavity 121 is called a horizontal plate 13, and the heating plate 15 mounted on both sides of any one of the partitioned spaces is called a vertical plate 25. . In detail, the vertical plate 15 also includes a heater unit 133 and a heat storage unit 132 like the horizontal plate 13, and the heater unit 133 and the heat storage unit 132 of the vertical plate 15. May also be selectively separated. The vertical plate 15 may be mounted to the cavity 121 in such a manner that the hook portion formed on the vertical plate 15 is caught by a locking portion provided on the inner surface of the cavity 121. Of course, the manner in which the vertical plate 15 is mounted to the cavity 121 is not limited thereto and may be various ways. In addition, according to the mounting method of the vertical plate 15, the vertical plate 15, like the heating plate 13, regardless of the direction in which the heater unit 133 and the heat storage unit 132 is directed to the cavity. It may be mounted to 121.

The horizontal plate 13 and the vertical plate 15 are mounted to the cavity 121 at the same time as shown in FIG. 8. Here, the horizontal plate 13 and the vertical plate 15 are placed so that the heat storage unit 132 is exposed in the upper space of the two spaces partitioned by the horizontal plate 13. Accordingly, the food accommodated in the upper space of the two spaces can be gradually heated and cooked simultaneously by the horizontal plate 13 and the vertical plate 15. In addition, since the heat by the heater located on the upper surface of the cavity can be concentrated to the food, the cooking efficiency is further improved. In other words, by the vertical plate 15 it is possible to cook more smooth brick oven.

However, if a separate heat storage unit 132 for storing and discharging heat generated from the upper heater is further provided below the heater above the cavity 121, the food accommodated in the upper space of the two spaces. Since the heating is made through the heat storage unit 132 in all directions, the gradual heating and cooking performance of the food may be further maximized.

Hereinafter, a method of controlling the operation of the cooking appliance will be described in detail with reference to the accompanying drawings.

9 is a control block diagram showing the control signal flow of the first embodiment of the cooking appliance according to the present invention.

Referring to FIG. 9, the cooking appliance 1 includes an input unit 161 for inputting various signals for controlling the operation of the cooking appliance 1, the horizontal plate 13, and the vertical plate 15. Detachable detection unit 162 for detecting the attachment and detachment, a control unit 163 to transmit a signal input to the input unit 161 and the signal detected by the detachment detection unit 162 and the cooking apparatus 1 of The memory unit 164 stores various types of information for operation, an output unit 165 for outputting various signals that can be recognized by the user, and a cooking operation unit 166 for cooking the food.

In detail, the input unit 161 is a part to which various signals for controlling the operation of the cooking appliance 1 can be input, and may be provided in various ways such as a button or a dial. In addition, the detachment detecting unit 162 is a device for detecting whether at least one of the horizontal plate 13 and the vertical plate 15 is mounted in the cavity 121, and the horizontal plate 13 ) And a proximity sensor method for detecting whether the vertical plate 15 is approaching, and a method for detecting whether the horizontal plate 13 and the vertical plate 15 are supplied with power.

Next, the memory unit 164 may store various information necessary for cooking of the food, such as set cooking conditions. In addition, the output unit 165 outputs an audio signal such as sound and voice or a visual signal such as text and color, so that the user can recognize various information. The cooking operation unit 166 may mean a portion for substantially cooking the food, and may correspond to, for example, each heater, burner, or fan.

Meanwhile, the cooking appliance 1 may be operated in a brick oven cooking mode. The brick oven cooking mode means that cooking is performed in a state in which both the horizontal plate 13 and the vertical plate 15 are mounted in the cavity 121. However, when the user does not mount at least one of the horizontal plate 13 and the vertical plate 15, the cooker 1 may input a signal for operating in the brick oven cooking mode. have.

Therefore, when the operation signal of the brick oven cooking mode is input through the input unit 161, the detachment detecting unit 162 detects whether the horizontal plate 13 and the vertical plate 15 are mounted. When it is detected that both the horizontal plate 13 and the vertical plate 15 are mounted, the control unit 163 operates the cooking operation unit 166 to perform normal cooking.

However, when it is detected that at least one of the horizontal plate 13 and the vertical plate 15 is not mounted, the control unit 163 uses the horizontal plate 13 and the vertical plate through the output unit 165. A signal indicating that at least one of the 15) is not mounted is output. By the signal output through the output unit 165, the user may recognize that at least one of the horizontal plate 13 and the vertical plate 15 is not mounted, and take steps to ensure that both are normally mounted.

On the other hand, in order to perform the normal brick oven cooking mode, the horizontal plate 13 should be mounted so that the heat storage unit 132 is positioned above the heater unit 133. Therefore, the horizontal plate 13 may be detected whether or not it is normally mounted, and if the horizontal plate 13 is mounted in the opposite manner, the user may be notified of the horizontal plate 13 and the action may be performed in a normal state.

When the horizontal plate 13 is mounted at the normal position by detecting whether the horizontal plate 13 is mounted at the normal position, the control unit 163 performs the cooking operation unit 166 to perform the brick oven cooking mode. ).

However, when the horizontal plate 13 is not mounted at the normal position, the control unit 163 outputs the warning signal indicating that the horizontal plate 13 is incorrectly mounted. To control. Accordingly, the user who has recognized the warning signal output from the output unit 165 may take measures to mount the horizontal plate 13 at a normal position.

In addition, when operating in the brick oven cooking mode, the horizontal plate 13 should be mounted in a position that partitions the inside of the cavity 121. However, when the operation signal of the brick oven cooking mode is input while the horizontal plate 13 is mounted on the bottom surface, a method of notifying the user that the mounting position of the horizontal plate 13 is incorrect is also described above. It is possible in the same way as the method.
