Description

Technical Field

[0001] This invention relates to cooking equipment. Background Technology

[0002] Cooking appliances are household appliances used to cook food using heat. Based on the location of the heater, which serves as the heat source, cooking appliances can be divided into open-type and closed-type cooking appliances. Closed-type cooking appliances include ovens and microwave ovens, while open-type cooking appliances include induction cookers and gas stoves.

[0003] Users can use the control panel located on the cooking appliance to turn the heater on / off or adjust its heating level. However, accidental operation by the user may activate the heater. For example, the control panel might be operated by a child or pet, or the heater might be activated due to accidental user operation. If the heater is activated unintentionally, there is a possibility of fire.

[0004] To address this issue, existing cooking appliances include a locking function. If the user activates the locking function, all operating functions of the cooking appliance are deactivated, thus preventing accidental activation of the heater. However, if the user does not activate the locking function, the possibility of accidental heater activation still exists. Summary of the Invention

[0151] Additionally, the horizontal direction orthogonal to the front-back direction of the cooking equipment, i.e., the width direction of the cooking equipment when viewed from the front of the door, can be called the left-right direction. For ease of explanation, the left-right direction can be called the second direction. Thus, the right side can be called one direction of the second direction, and the left side can be called another direction of the second direction.

[0152] Furthermore, the width direction of the cooking device can also be referred to as the lateral direction. Thus, the right side can be referred to as one side of the lateral direction, and the left side can be referred to as the other side of the lateral direction.

[0153] Furthermore, the aforementioned vertical direction can be referred to as a third direction. Thus, upward can be called one direction of the third direction, and downward can be called another direction of the third direction.

[0154] Furthermore, the aforementioned up-down direction can be referred to as the vertical direction. Therefore, the front-back direction and the left-right direction, i.e., the first and second directions, can be collectively referred to as the horizontal direction.

[0155] In the instruction manual, unless otherwise stated, "A and / or B" means A, B, or A and B, and unless otherwise stated, "C to D" means greater than or equal to C and less than or equal to D.

[0156] Figure 1 This is a front view of a cooking apparatus according to one embodiment. Furthermore, Figure 2 It shows Figure 1 The cooking appliance shown includes the gas stove and control panel. Additionally... Figure 3 It shows Figure 2 A portion of the control panel shown.

[0157] Reference Figures 1 to 3 One embodiment of the cooking apparatus 10 includes a gas stove section 100 and an oven section 200. However, the operation and control methods of the cooking apparatus described below are not only applicable to the cooking apparatus 10 that includes both the gas stove section 100 and the oven section 200. For example, the operation and control methods of the cooking apparatus described below can also be applied to a cooking apparatus that includes only the gas stove section 100 or a cooking apparatus that includes only the oven section 200.

[0158] The gas stove section 100 can be configured above the oven section 200. The gas stove section 100 may include a top plate 110, which forms the appearance of the upper surface of the cooking device 10 and is capable of holding a container for food.

[0159] The top plate 110 may include one or more heating zones 121 to 125. Figure 1 and Figure 2An embodiment is shown in which the top plate 110 includes five heating zones 121 to 125. However, this is only an example, and the number of heating zones formed in the top plate 110 may vary depending on the embodiment.

[0160] A heater for heating the container located above each of the heating zones 121 to 125 can be disposed at the lower part of each heating zone 121 to 125. In one embodiment, if the gas stove unit 100 is an induction heating device, the heater can be a heating coil driven by alternating current to heat the container. In another embodiment, if the gas stove unit 100 is a radiant heating device, the heater can be a planar heating element or a radiant burner that heats the container using radiant heat. In yet another embodiment, the heater can be an electric heating coil or an electric heating plate that generates its own heat using electrical energy. In yet another embodiment, the heater can be a gas burner that heats the container by burning gas. However, the type of heater is not limited to these, and the gas stove unit 100 may also include other types of heaters.

[0161] The oven section 200 can be configured below the gas stove section 100. Inside the oven section 200, a cooking chamber for heating food or containers containing food can be formed. Inside the cooking chamber, a heater for heating food or containers containing food can be configured. Examples of heaters include heating coils, planar heating elements or radiant burners, electric heating coils, electric heating plates, gas burners, convection heaters, etc., but the type of heater is not limited to these.

[0162] A door 210 for opening and closing the cooking chamber can be provided on the front of the oven section 200. The door 210 can rotate up and down about the lower end of the oven section 200 or rotate back and forth about the left or right side of the oven section 200. A handle for opening and closing the door 210 can be installed on one side of the door 210.

[0163] In one embodiment, the cooking appliance 10 may include a control panel 111. For example, such as Figure 1 As shown, the control panel 111 can be configured between the gas stove section 100 and the oven section 200, facing the front of the cooking appliance 10. However, the configuration location of the control panel 111 is not limited to this.

[0164] In one embodiment, the control panel 111 may include one or more heating operation units 131 to 135, 220 for controlling the operation of the cooking appliance 10. Each heating operation unit 131 to 135, 220 may correspond one-to-one with a respective heating zone 121 to 125. For example, the control panel 111 may include a first heating operation unit 131 to a fifth heating operation unit 135 for controlling the operation of the first heating zone 121 to the fifth heating zone 125 and a sixth heating operation unit 220 for controlling the operation of the oven unit 200. Figures 1 to 3 The control panel 111 shown is only an exemplary embodiment, and the number and configuration position of the heating operation parts included in the control panel 111 may vary depending on the embodiment.

[0165] In one embodiment, each heating operation unit 131 to 135, 220 is a rotatable knob. For example, the knob may be a push-and-turn type knob driven by a pressing and rotating action. As another example, the knob may also be a rotary knob driven only by a rotating action without a pressing action. The user can drive the heaters configured in each heating zone 121 to 125 or the oven section 200, or adjust the heating level or temperature of the heaters, or stop the operation of the heaters by rotating the knobs.

[0166] When the heating operation units 131 to 135, 220 are knobs, the state in which the knob remains in its initial position can be defined as the heating operation units 131 to 135, 220 being in the off state. Furthermore, the state in which the knob is rotated to a position other than the initial position can be defined as the heating operation units 131 to 135, 220 being in the on state. However, the types of heating operation units 131 to 135, 220 are not limited to this, and the heating operation units 131 to 135, 220 can also be implemented as other types of devices.

[0167] In one embodiment, the control panel 111 may include a display panel 150. The display panel 150 may display information related to the operation of the cooking appliance 10. Furthermore, the display panel 150 may include one or more operating parts for controlling the operation of the cooking appliance 10. For example, the one or more operating parts for controlling the operation of the cooking appliance 10 on the display panel 150 may be implemented as physical buttons or touch-operated buttons. At least a portion of the display panel 150 may be implemented as a touch panel.

[0168] In one embodiment, the display panel 150 may include a safety operation unit 163. A user can change the safety operation unit 163 to an on or off state by pressing or touching it. In one embodiment, the display panel 150 may include a safety operation unit status display area 165 that displays the on / off state of the safety operation unit 163.

[0169] For example, when the safety operating unit 163 is in the off state, the safety operating unit status display area 165 can remain off. When the safety operating unit 163 is in the off state, if the user presses or touches the safety operating unit 163, the safety operating unit 163 can be turned on. If the safety operating unit 163 is turned on, the safety operating unit status display area 165 can remain lit.

[0170] In one embodiment, even if the safety operation unit 163 is in the on state, the controller 30 can keep the safety operation unit status display area 165 in the off state, and turn on the safety operation unit status display area 165 when the specified conditions are met.

[0171] If the safety operation unit 163 is in the closed state, the safety functions described later can be deactivated. If the safety operation unit 163 is in the open state, the safety functions described later can be activated.

[0172] exist Figure 3 In the illustrated embodiment, the security operation unit 163 can have two functions. For example, when a user briefly presses or touches the security operation unit 163 (e.g., less than 5 seconds), the user can use the security operation unit 163 to control the security functions described later. When a user presses or touches the security operation unit 163 for a long time (e.g., more than 5 seconds), the user can use the security operation unit 163 to control the existing locking function. However, in another embodiment, the security operation unit 163 can also be implemented to control only the security functions described later.

[0173] In another embodiment, the safety operation unit 163 may also be configured in a different location than the display panel 150.

[0174] In one embodiment, the control panel 111 may include an operation indicator light 160. The operation indicator light 160 may indicate the operating status of the heaters, the operating status of the heating operation units 131 to 135, 220, or the on / off state of the safety switch described later. For example, the operation indicator light 160 may be illuminated when the heaters are in a state where power can be supplied to any one of the plurality of heaters included in the cooking appliance 10 to drive the heaters; if not all heaters are in a driveable state, the operation indicator light 160 may be extinguished. As another example, the operation indicator light 160 may be illuminated when the heating operation units 131 to 135, 220 change from an off state to an on state, and may be extinguished when the heating operation units 131 to 135, 220 change from an on state to an off state. As another example, the operation indicator light 160 may be illuminated when the safety switch described later is closed, and may be extinguished when the safety switch is open.

[0175] In one embodiment, the control panel 111 may include a temperature indicator light 170. The temperature indicator light 170 may indicate the temperature of the heaters included in the cooking appliance 10. For example, the temperature indicator light 170 may be illuminated if the temperature of any one of the plurality of heaters included in the cooking appliance 10 is above a predetermined reference temperature, and may be turned off if the temperature of all heaters is below the reference temperature.

[0176] Figure 4 This is a schematic diagram illustrating the configuration of a cooking apparatus according to one embodiment. Figure 5 This is a schematic diagram illustrating the configuration of a cooking apparatus according to another embodiment.

[0177] Reference Figure 4 and Figure 5 The cooking device 10 may include a heater 120, a heating operation unit 130, a safety operation unit 163, a controller 30, a heating switch HS, and a safety switch SS.

[0178] A first power supply line L1 and a second power supply line L2 can be connected between the heater 120 and the external power supply 1. The heater 120 can be driven by the power supplied from the external power supply 1 through the first power supply line L1 and the second power supply line L2. As an example, the external power supply 1 can be a single-phase four-wire AC power supply, but the type of external power supply 1 is not limited to this.

[0179] As an example, heater 120 may be any one of a plurality of heaters disposed in the lower part of the heating zones 121 to 125 of the cooking device 10 described above.

[0180] A heating switch HS and a safety switch SS can be respectively configured between the external power supply 1 and the heater 120.

[0181] One end of the heating switch HS can be connected to the first power supply line L1, and the other end of the heating switch HS can be connected to the heater 120. One end of the safety switch SS can be connected to the second power supply line L2, and the other end of the safety switch SS can be connected to the heater 120.

[0182] In one embodiment, a heating level adjustment switch LS may be connected between the safety switch SS and the heater 120. One end of the heating level adjustment switch LS may be connected to the safety switch SS, and the other end of the heating level adjustment switch LS may be connected to the heater 120.

[0183] The heating operation unit 130 can be used to adjust the on / off states of the heating switch HS and the heating level adjustment switch LS. That is, the heating operation unit 130 can be used to control the operation of the heater 120. For example, if the user changes the heating operation unit 130 from the off state to the on state, the heating switch HS can be closed. If the user changes the heating operation unit 130 from the on state to the off state, the heating switch HS can be opened. Furthermore, if the user uses the heating operation unit 130 to set the heating level of the heater 120, the heating level adjustment switch LS can be repeatedly opened and closed according to the user-set heating level. The opening and closing time, opening and closing interval, and number of opening and closing cycles of the heating level adjustment switch LS can be set differently for each heating level.

[0184] As an example, the heating operation unit 130 can be any one of the heating operation units 131 to 135 and 220 described above.

[0185] The safety operation unit 163 can be used to activate or deactivate the safety functions of the cooking appliance 10. For example, to activate the safety function, the user can change the safety operation unit 163 from the off state to the on state. Conversely, to deactivate the safety function, the user can change the safety operation unit 163 from the on state to the off state. According to an embodiment, the controller 30 can be used to change the safety operation unit 163 from the on state to the off state.

[0186] The controller 30 can control the opening and closing state of the safety switch SS according to the operation of the safety operation unit 163. For example, if the safety operation unit 163 changes from the closed state to the open state, the controller 30 can control it to close the safety switch SS. Conversely, if the safety operation unit 163 changes from the open state to the closed state, the controller 30 can control it to open the safety switch SS.

[0187] As described below, even if the safety operation unit 163 changes from the closed state to the open state, the controller 30 can control it to close the safety switch SS only when a specific condition is met. Furthermore, when the safety operation unit 163 is in the open state, the controller 30 can control it to open the safety switch SS if a specific condition is met.

[0188] In this invention, the closed state of the safety switch SS can be referred to as the state in which the safety function is activated. Furthermore, the open state of the safety switch SS can be referred to as the state in which the safety function is deactivated.

[0189] When the safety function is activated, i.e., when the safety switch SS is closed, the user can control the operation of the heater 120 through the heating operation unit 130. If the safety function is deactivated, i.e., when the safety switch SS is open, the heater will not be activated even if the user operates the heating operation unit 130.

[0190] As an example, controller 30 can be implemented as any of a central processing unit (CPU), micro-controller, application processor (AP), communication processor (CP), ARM processor, and microcontroller.

[0191] In one embodiment, the cooking device 10 may further include an action indicator light 160.

[0192] The operation indicator light 160 can indicate the operation status of the heater 120, the operation status of the heating operation unit 130, or the on / off status of the safety switch SS.

[0193] For example, such as Figure 4 As shown, one end of the action indicator light 160 can be connected to the other end of the heating switch HS, and the other end of the action indicator light 160 can be connected to one end of the safety switch SS. If the action indicator light 160... Figure 4 With this configuration, the operation indicator 160 can be turned on or off depending on the on / off state of the heating switch HS. As a result, the operation indicator 160 can indicate the driving state of the heater 120. Furthermore, since the heating switch HS can be turned on and off using the heating operation unit 130, the operation indicator 160 can also indicate the operating state of the heating operation unit 130, that is, the on / off state of the heating operation unit 130.

[0194] As another example, such as Figure 5As shown, one end of the action indicator light 160 can be connected to one end of the heating switch HS, and the other end of the action indicator light 160 can be connected to the other end of the safety switch SS. If the action indicator light 160... Figure 5 With this configuration, the operation indicator light 160 can be turned on or off according to the open / closed state of the safety switch SS. As a result, the operation indicator light 160 can indicate the open / closed state of the safety switch SS, in other words, whether the safety function is activated.

[0195] In one embodiment, the cooking device 10 may further include a speaker (not shown). The speaker (not shown) can output sound according to the control of the controller 30.

[0196] Figure 6 This is a schematic diagram illustrating the configuration of a cooking apparatus according to another embodiment. Figure 7 This is a schematic diagram illustrating the configuration of a cooking apparatus according to another embodiment.

[0197] Reference Figure 6 and Figure 7 The cooking device 10 may include a heater 120, a heating operation unit 130, a safety operation unit 163, a controller 30, a heating switch HS, and a safety switch SS.

[0198] A first power supply line L1 and a second power supply line L2 can be connected between the heater 120 and the external power supply 1. The heater 120 can be driven by the power supplied from the external power supply 1 through the first power supply line L1 and the second power supply line L2. As an example, the external power supply 1 can be a single-phase four-wire AC power supply, but the type of external power supply 1 is not limited to this.

[0199] As an example, heater 120 may be any one of a plurality of heaters disposed in the lower part of the heating zones 121 to 125 of the cooking device 10 described above.

[0200] In one embodiment, a heating switch HS, a heating level adjustment switch LS, and a safety switch SS may be respectively configured between the external power supply 1 and the heater 120.

[0201] One end of the heating switch HS can be connected to the first power supply line L1. The other end of the heating switch HS can be connected to the heater 120.

[0202] One end of the safety switch SS can be connected to either the first power supply line L1 or the second power supply line L2. The other end of the safety switch SS can be connected to the heater 120.

[0203] like Figure 6As shown, in one embodiment, one end of the heating switch HS can be connected to the first power supply line L1, and the other end of the heating switch HS can be connected to the heater 120. Additionally, one end of the safety switch SS can be connected to the other end of the heating level adjustment switch LS, and the other end of the safety switch SS can be connected to the heater 120. That is, the safety switch SS can be connected between the heating level adjustment switch LS and the heater 120.

[0204] like Figure 7 As shown, in another embodiment, one end of the heating switch HS can be connected to the first power supply line L1, and the other end of the heating switch HS can be connected to one end of the safety switch SS. Additionally, one end of the safety switch SS can be connected to the other end of the heating switch HS, and the other end of the safety switch SS can be connected to the heater 120. That is, the safety switch SS can be connected between the heating switch HS and the heater 120.

[0205] The heating operation unit 130 can be used to adjust the on / off states of the heating switch HS and the heating level adjustment switch LS. That is, the heating operation unit 130 can be used to adjust the operation of the heater 120. For example, if the user changes the heating operation unit 130 from the off state to the on state, the heating switch HS can be closed. If the user changes the heating operation unit 130 from the on state to the off state, the heating switch HS can be opened. Furthermore, if the user uses the heating operation unit 130 to set the heating level of the heater 120, the heating level adjustment switch LS can be repeatedly opened and closed according to the user-set heating level. The opening and closing time, opening and closing interval, and number of opening and closing cycles of the heating level adjustment switch LS can be set differently for each heating level.

[0206] As an example, the heating operation unit 130 can be any one of the heating operation units 131 to 135 and 220 described above.

[0207] The safety function of the cooking appliance 10 can be activated or deactivated using the safety operation unit 163. For example, to activate the safety function, the user can change the safety operation unit 163 from the off state to the on state. Conversely, to deactivate the safety function, the user can change the safety operation unit 163 from the on state to the off state. According to an embodiment, the controller 30 can be used to change the safety operation unit 163 from the on state to the off state.

[0208] The controller 30 can control the opening and closing state of the safety switch SS according to the operation of the safety operation unit 163. For example, if the safety operation unit 163 changes from the closed state to the open state, the controller 30 can control it to close the safety switch SS. Conversely, if the safety operation unit 163 changes from the open state to the closed state, the controller 30 can control it to open the safety switch SS.

[0209] As described below, even if the safety operation unit 163 changes from the closed state to the open state, the controller 30 can control it to close the safety switch SS only when a specific condition is met. Furthermore, when the safety operation unit 163 is in the open state, the controller 30 can control it to open the safety switch SS if a specific condition is met.

[0210] In this invention, the closed state of the safety switch SS can be referred to as the state in which the safety function is activated. Furthermore, the open state of the safety switch SS can be referred to as the state in which the safety function is deactivated.

[0211] When the safety function is activated, i.e., the safety switch SS is closed, the user can control the operation of the heater 120 through the heating operation unit 130. If the safety function is deactivated, i.e., the safety switch SS is open, the heater will not be activated even if the user operates the heating operation unit 130.

[0212] As an example, controller 30 can be implemented as any of a central processing unit (CPU), micro-controller, application processor (AP), communication processor (CP), ARM processor, and microcontroller.

[0213] In one embodiment, the cooking device 10 may further include an action indicator light 160.

[0214] The operation indicator light 160 can indicate the operation status of the heater 120, the operation status of the heating operation unit 130, or the on / off status of the safety switch SS.

[0215] For example, such as Figure 6 As shown, one end of the operation indicator light 160 can be connected to the other end P1 of the heating switch HS, and the other end of the operation indicator light 160 can be connected to one end P2 of the heating level adjustment switch LS. As another example, as... Figure 7 As shown, one end of the operation indicator light 160 can be connected to the other end P1 of the heating switch HS, and the other end of the operation indicator light 160 can be connected to one end P2 of the heating level adjustment switch LS. In this case, the operation indicator light 160 can be turned on or off according to the on / off state of the heating switch HS. As a result, the operation indicator light 160 can indicate the driving state of the heater 120. Furthermore, since the heating switch HS can be turned on and off using the heating operation unit 130, the operation indicator light 160 can also indicate the operating state of the heating operation unit 130, that is, the on / off state of the heating operation unit 130.

[0216] In another embodiment, such as Figure 6 As shown, one end of the action indicator light 160 can be connected to one end P3 of the safety switch SS, and the other end of the action indicator light 160 can be connected to the other end P4 of the safety switch SS. In another embodiment, as... Figure 7 As shown, one end of the operation indicator light 160 can be connected to the other end P5 of the safety switch SS, and the other end of the operation indicator light 160 can be connected to one end P2 of the heating level adjustment switch LS. In this case, the operation indicator light 160 can be lit or turned off according to the open or closed state of the safety switch SS. As a result, the operation indicator light 160 can indicate the open or closed state of the safety switch SS, in other words, whether the safety function is activated.

[0217] In one embodiment, the cooking device 10 may further include a speaker (not shown). The speaker (not shown) can output sound according to the control of the controller 30.

[0218] Figure 8 This is a schematic diagram illustrating the configuration of a cooking apparatus according to another embodiment. Figure 9 This is a schematic diagram illustrating the configuration of a cooking apparatus according to another embodiment.

[0219] Reference Figure 8 and Figure 9 The cooking device 10 may include a heater 120, a heating operation unit 130, a safety operation unit 163, a controller 30, a heating switch HS, and a safety switch SS.

[0220] A first power supply line L1 and a second power supply line L2 are connected between the heater 120 and the external power supply 1. The heater 120 can be driven by the power supplied from the external power supply 1 through the first power supply line L1 and the second power supply line L2. As an example, the external power supply 1 can be a single-phase four-wire AC power supply, but the type of external power supply 1 is not limited to this.

[0221] As an example, heater 120 may be any one of a plurality of heaters disposed in the lower part of the heating zones 121 to 125 of the cooking device 10 described above.

[0222] A heating switch HS and a safety switch SS can be respectively configured between the external power supply 1 and the heater 120.

[0223] One end of the heating switch HS can be connected to the first power supply line L1, and the other end of the heating switch HS can be connected to the heater 120. One end of the safety switch SS can be connected to the second power supply line L2, and the other end of the safety switch SS can be connected to the heater 120.

[0224] An encoder 180 may be configured between the heating operation unit 130 and the controller 30. The encoder 180 can detect whether the heating operation unit 130 is turned on / off and the rotational position of the heating operation unit 130, and transmit the detected information about whether the heating operation unit 130 is turned on / off and the rotational position of the heating operation unit 130 to the controller 30.

[0225] The heating operation unit 130 can be used to adjust the opening and closing state of the heating switch HS. That is, the heating operation unit 130 can be used to control the operation of the heater 120. The controller 30 can control the opening and closing state of the heating switch HS according to the operation of the heating operation unit 130. For example, if the user changes the heating operation unit 130 from the closed state to the open state, the controller 30 can close the heating switch HS. If the user changes the heating operation unit 130 from the open state to the closed state, the controller 30 can open the heating switch HS. Furthermore, if the user uses the heating operation unit 130 to set the heating level of the heater 120, the controller 30 can control the heating level adjustment switch LS to repeatedly open and close according to the heating level set by the user. The opening and closing time, opening and closing interval, and number of opening and closing cycles of the heating level adjustment switch LS can be set differently for each heating level.

[0226] As an example, the heating operation unit 130 can be any one of the heating operation units 131 to 135 and 220 described above.

[0227] The safety operation unit 163 can activate or deactivate the safety functions of the cooking appliance 10. For example, to activate the safety function, the user can change the safety operation unit 163 from the off state to the on state. Conversely, to deactivate the safety function, the user can change the safety operation unit 163 from the on state to the off state. According to an embodiment, the controller 30 can be used to change the safety operation unit 163 from the on state to the off state.

[0228] The controller 30 can control the opening and closing state of the safety switch SS according to the operation of the safety operation unit 163. For example, if the safety operation unit 163 changes from the closed state to the open state, the controller 30 can control it to close the safety switch SS. Conversely, if the safety operation unit 163 changes from the open state to the closed state, the controller 30 can control it to open the safety switch SS.

[0229] As described below, even if the safety operation unit 163 changes from the closed state to the open state, the controller 30 can control it to close the safety switch SS only when a specific condition is met. Furthermore, when the safety operation unit 163 is in the open state, the controller 30 can control it to open the safety switch SS if a specific condition is met.

[0230] When the safety function is activated, i.e., the safety switch SS is closed, the user can control the operation of the heater 120 through the heating operation unit 130. If the safety function is deactivated, i.e., the safety switch SS is open, the heater 120 will not be activated even if the user operates the heating operation unit 130.

[0231] As an example, controller 30 can be implemented as any of a central processing unit (CPU), micro-controller, application processor (AP), communication processor (CP), ARM processor, and microcontroller.

[0232] In one embodiment, the cooking device 10 may further include an action indicator light 160.

[0233] The operation indicator light 160 can indicate the operation status of the heater 120, the operation status of the heating operation unit 130, or the on / off status of the safety switch SS.

[0234] For example, such as Figure 8 As shown, one end of the action indicator light 160 can be connected to the other end of the heating switch HS, and the other end of the action indicator light 160 can be connected to one end of the safety switch SS. If the action indicator light 160... Figure 8 With this configuration, the operation indicator 160 can be turned on or off depending on the on / off state of the heating switch HS. As a result, the operation indicator 160 can indicate the driving state of the heater 120. Furthermore, since the heating switch HS can be turned on and off using the heating operation unit 130, the operation indicator 160 can also indicate the operating state of the heating operation unit 130, that is, the on / off state of the heating operation unit 130.

[0235] As another example, such as Figure 9 As shown, one end of the action indicator light 160 can be connected to one end of the heating switch HS, and the other end of the action indicator light 160 can be connected to the other end of the safety switch SS. If the action indicator light 160... Figure 9 With this configuration, the operation indicator light 160 can be turned on or off according to the open / closed state of the safety switch SS. As a result, the operation indicator light 160 can indicate the open / closed state of the safety switch SS, in other words, whether the safety function is activated.

[0236] In one embodiment, the cooking device 10 may further include a speaker (not shown). The speaker (not shown) can output sound according to the control of the controller 30.

[0237] Figure 10This is a flowchart illustrating a control method for a cooking apparatus according to an embodiment.

[0238] When the safety operation unit 163 is in the closed state and the safety switch SS is in the open state, the controller 30 can confirm whether the safety option is in the open state (400).

[0239] In step 400, if it is confirmed that the safety option is in the off state, the controller 30 can confirm whether any one of the heating operation units 130 has been changed to the on state (420).

[0240] In step 420, if it is confirmed that there is no heater that has changed to the on state, the controller 30 may then execute step 420.

[0241] In step 420, if any one of the heating operation units 130 is switched on, the heating switch HS corresponding to the switched-on heating operation unit can be closed (421). Furthermore, in step 420, if it is confirmed that any one of the heating operation units 130 is switched on, the controller 30 can control the closing of the safety switch SS corresponding to the switched-on heating operation unit (422). Accordingly, power can be supplied to the heater 120 corresponding to the switched-on heating operation unit via the first power supply line L1 and the second power supply line L2. This allows the heater 120 corresponding to the switched-on heating operation unit to be driven.

[0242] Subsequently, if the heating operation unit of another heater is changed to the on state (410), the heating switch corresponding to the other heating operation unit 130 that has been changed to the on state can be closed to drive the other heater (411). In step 410, if the heating operation unit of another heater is not changed to the on state, the control can be terminated.

[0243] In step 400, if it is confirmed that the safety option is enabled, the controller 30 can confirm whether there is a driven heater among the one or more heaters included in the cooking device 10 (401).

[0244] In another embodiment, if the cooking device 10 does not have a safety option setting function, steps 400, 420, 421, and 422 can be omitted. In this case, if the cooking device 10 starts operating, the controller 30 can execute the commands first. Figure 10 Step 401 is shown.

[0245] In step 401, if a heater is being driven, step 410 can be executed. In step 410, the heating operation unit 130 corresponding to the other heater that is not being driven is turned on, and the heating switch corresponding to the other heating operation unit 130 that has been turned on is closed, thereby driving the other heater (411). In step 410, if the heating operation unit of the other heater has not been turned on, control can be terminated.

[0246] In step 401, if it is confirmed that all heaters are not in operation, the controller 30 can confirm whether the safety operation unit 163 has changed from the off state to the on state (402).

[0247] In step 402, if it is confirmed that the safety operation unit 163 has not been changed to the on state, the controller 30 can confirm whether any one of the heating operation units 130 is in the on state (409).

[0248] In step 409, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 may then execute step 402.

[0249] In step 409, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may terminate control. In another embodiment, in step 409, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may terminate control after executing the second warning action described later.

[0250] In step 402, if it is confirmed that the safety operation unit 163 has changed to the on state, the controller 30 can confirm whether all heating operation units 130 are in the off state (403). In step 402, if it is confirmed that the safety operation unit 163 is in the on state, the controller 30 can illuminate the safety operation unit status display area 165.

[0251] In step 402, even if the safety operation unit 163 is confirmed to be in the open state, the controller 30 can keep the safety switch SS in the open state.

[0252] In step 403, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 can change the safety operation unit 163 to the off state (406). If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the safety operation unit status display area 165. After executing step 406, the controller 30 can then execute step 401.

[0253] In step 403, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 can confirm whether any one of the heating operation units 130 has been changed to the on state (404).

[0254] In step 404, if it is confirmed that the heating operation unit 130 has not changed to the on state, the controller 30 can confirm whether the first standby time has elapsed (405). The first standby time can be set differently depending on the embodiment.

[0255] In step 405, if it is confirmed that the first standby time has not elapsed, the controller 30 may then execute step 404.

[0256] In step 405, if it is confirmed that the first standby time has elapsed, the controller 30 can change the safety operation unit 163 to the off state (406). If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the lights in the safety operation unit status display area 165. After executing step 406, the controller 30 can then execute step 401.

[0257] According to steps 402 to 406, after the safety operation unit 163 changes from the off state to the on state, if the heating operation unit 130 is not operated within a specified time (first standby time), the safety operation unit 163 automatically changes back to the off state. Through this control, even if the safety operation unit 163 changes to the on state, if the heating operation unit 130 is not operated within the specified time, the safety operation unit 163 returns to the off state, thereby maintaining a safer state for the cooking equipment 10.

[0258] In step 404, if any one of the heating operation units 130 changes to the on state, the heating switch HS can be closed (407). Furthermore, in step 404, if it is confirmed that any one of the heating operation units 130 has changed to the on state, the controller 30 can control the closing of the safety switch SS corresponding to the heating operation unit that has changed to the on state (408). Accordingly, power can be supplied to the heater 120 corresponding to the heating operation unit that has changed to the on state via the first power supply line L1 and the second power supply line L2. Accordingly, the heater 120 corresponding to the heating operation unit that has changed to the on state can be driven.

[0259] In other words, when the safety operation unit 163 is in the open state and the heating operation unit 130 is in the closed state, if the heating operation unit 130 is changed to the open state, the controller 30 can control it to close the safety switch SS.

[0260] With this control, the user can operate the heating operation unit 130 to drive the heater only when all heating operation units 130 are in the off state and the user changes the safety operation unit 163 to the on state.

[0261] In the action indicator light 160, such as Figure 4 or Figure 6 or Figure 7 or Figure 8 In that configuration, since the heating switch HS is closed in step 407, the operation indicator light 160 can be illuminated. Based on this, the user can confirm that the heater 120 is activated or the heating operation unit 130 is in the on state.

[0262] In the action indicator light 160, such as Figure 5 or Figure 9 With that configuration, since the safety switch SS is closed in step 408, the action indicator light 160 will illuminate. Based on this, the user can confirm that the safety function is activated.

[0263] After the heater is driven in step 408, step 410 can be executed. If the heating operation unit 130 corresponding to the other heater that is not being driven is changed to the on state in step 410, the heating switch corresponding to the other heating operation unit 130 that has changed to the on state is closed, thereby driving the other heater (411). If the heating operation unit of the other heater is not changed to the on state in step 410, the control can be terminated.

[0264] Figure 11 This is a flowchart illustrating a control method for a cooking apparatus according to another embodiment.

[0265] When the safety operation unit 163 is in the closed state and the safety switch SS is in the open state, the controller 30 can confirm whether the safety option is in the open state (500).

[0266] In step 500, if it is confirmed that the safety option is in the off state, the controller 30 can confirm whether any one of the heating operation units 130 has been changed to the on state (520).

[0267] In step 520, if it is confirmed that there is no heater that has changed to the on state, the controller 30 may execute step 520 again.

[0268] In step 520, if any one of the heating operation units 130 is changed to the open state, the heating switch HS corresponding to the heating operation unit that has been changed to the open state can be closed (521).

[0269] Furthermore, in step 520, if it is confirmed that any one of the heating operation units 130 has changed to the on state, the controller 30 can control the safety switch SS corresponding to the heating operation unit that has changed to the on state to be closed (522). Accordingly, power can be supplied to the heater 120 corresponding to the heating operation unit that has changed to the on state through the first power supply line L1 and the second power supply line L2. Accordingly, the heater 120 corresponding to the heating operation unit that has changed to the on state can be driven.

[0270] Subsequently, if the heating operation unit of another heater is changed to the on state (516), the heating switch corresponding to the other heating operation unit 130 that has been changed to the on state is closed, so that the other heater can be driven (517). If the heating operation unit of another heater is not changed to the on state in step 516, the control can be terminated.

[0271] In step 500, if it is confirmed that the safety option is enabled, the controller 30 can confirm whether there is a driven heater among the one or more heaters included in the cooking device 10 (501).

[0272] In another embodiment, if the cooking device 10 does not have a safety option setting function, steps 500, 520, 521, and 522 can be omitted. In this case, if the cooking device 10 starts operating, the controller 30 can execute the commands first. Figure 11 Step 501 is shown.

[0273] In step 501, if a heater is in operation, step 516 can be executed. In step 516, if the heating operation unit 130 corresponding to another heater that is not in operation is turned on, the heating switch corresponding to the other heating operation unit 130 that is turned on is closed, thus enabling the other heater to be driven (517). In step 516, if the heating operation unit of another heater is not turned on, control can be terminated.

[0274] In step 501, if it is confirmed that all heaters are not in operation, the controller 30 can confirm whether the safety operation unit 163 has changed from the off state to the on state (502).

[0275] In step 502, if it is confirmed that the safety operation unit 163 has not been changed to the on state, the controller 30 can confirm whether any one of the heating operation units 130 is in the on state (514).

[0276] In step 514, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 may then execute step 502.

[0277] In step 514, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may end control after executing the second warning action (515). If the second warning action is executed, the controller 30 may control the image or text displayed on the display panel 150 to flash. As another example, if the second warning action is executed, the controller 30 may control the output of a warning sound or warning voice through a speaker. As yet another example, if the second warning action is executed, the controller 30 may control the flashing of the action indicator light 160.

[0278] In another embodiment, in step 514, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may not execute the second warning action and end the control.

[0279] In step 502, if it is confirmed that the safety operation unit 163 has changed to the on state, the controller 30 can confirm whether all heating operation units 130 are in the off state (503). In step 502, if it is confirmed that the safety operation unit 163 is in the on state, the controller 30 can illuminate the safety operation unit status display area 165.

[0280] In step 502, even if it is confirmed that the safety operation unit 163 is in the open state, the controller 30 can keep the safety switch SS in the open state.

[0281] In step 503, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 can change the safety operation unit 163 to the off state (504). If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the safety operation unit status display area 165. After executing step 504, the controller 30 can then execute step 501.

[0282] In step 503, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 can confirm whether any one of the heating operation units 130 has changed to the on state (505).

[0283] In step 505, if it is confirmed that the heating operation unit 130 has not changed to the on state, the controller 30 can confirm whether the first standby time has elapsed (506). The first standby time can be set differently depending on the embodiment.

[0284] In step 506, if it is confirmed that the first standby time has not elapsed, the controller 30 may then execute step 505.

[0285] In step 506, if it is confirmed that the first standby time has elapsed, the controller 30 may execute a first warning action (507). If the first warning action is executed, the controller 30 may control the image or text displayed on the display panel 150 to flash. As another example, if the first warning action is executed, the controller 30 may control the output of a warning sound or warning voice through a speaker. As yet another example, if the first warning action is executed, the controller 30 may control the flashing of the action indicator light 160.

[0286] During the execution of the first warning action, the controller 30 can confirm whether any one of the heating operation units 130 has changed to the on state (508).

[0287] In step 508, if any one of the heating operation units 130 changes to the on state, the heating switch HS can be closed (512). Furthermore, in step 508, if it is confirmed that any one of the heating operation units 130 has changed to the on state, the controller 30 can control the closing of the safety switch SS corresponding to the heating operation unit that has changed to the on state (513). Accordingly, power can be supplied to the heater 120 corresponding to the heating operation unit that has changed to the on state via the first power supply line L1 and the second power supply line L2. Accordingly, the heater 120 corresponding to the heating operation unit that has changed to the on state can be driven.

[0288] In step 508, if it is confirmed that the heating operation unit 130 has not changed to the open state, the controller 30 can check whether any other operation that is not an operation of the heating operation unit 130 has occurred (509). An example of other operations that are not an operation of the heating operation unit 130 could be the opening or closing of the door 210.

[0289] In step 509, if it is confirmed that an operation other than the operation of the heating operation unit 130 has occurred, the controller 30 may end the first warning action (511) and end control.

[0290] In step 509, if it is confirmed that no other operation other than the operation of the heating operation unit 130 has occurred, the controller 30 can confirm whether a predetermined second standby time (510) has elapsed. The second standby time can be set differently depending on the embodiment.

[0291] In step 510, if it is confirmed that the second standby time has not elapsed, the controller 30 may then execute steps 507 to 509.

[0292] In step 510, if it is confirmed that the second standby time has elapsed, the controller 30 can change the safety operation unit 163 to the off state (504). If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the safety operation unit status display area 165. After executing step 504, the controller 30 can then execute step 501.

[0293] In step 505, if the heating operation unit 130 is changed to the on state, the heating switch HS can be closed (512). Furthermore, in step 505, if it is confirmed that the heating operation unit 130 has changed to the on state, the controller 30 can control the closing of the safety switch SS (513). Accordingly, power can be supplied to the heater 120 via the first power supply line L1 and the second power supply line L2, thereby driving the heater 120.

[0294] In other words, when the safety operation unit 163 is in the open state and the heating operation unit 130 is in the closed state, if the heating operation unit 130 is changed to the open state, the controller 30 can control it to close the safety switch SS.

[0295] With this control, the user can operate the heating operation unit 130 to drive the heater only when all heating operation units 130 are in the off state and the user changes the safety operation unit 163 to the on state.

[0296] In the action indicator light 160, such as Figure 4 or Figure 6 or Figure 7 or Figure 8 In that configuration, since the heating switch HS is closed in step 512, the operation indicator light 160 can be illuminated. Based on this, the user can identify whether the heater 120 is activated or the heating operation unit 130 is in the on state.

[0297] In the action indicator light 160, such as Figure 5 or Figure 9 With that configuration, since the safety switch SS is closed in step 513, the action indicator light 160 can be illuminated. Based on this, the user can recognize that the safety function is activated.

[0298] After the heater is driven in step 513, step 516 can be executed. In step 516, if the heating operation unit 130 corresponding to another heater that is not being driven is turned on, the heating switch corresponding to the other heating operation unit 130 that has been turned on is closed, thereby enabling the other heater to be driven (517). If the heating operation unit of the other heater is not turned on in step 516, the control can be terminated.

[0299] Figure 12 This is a flowchart illustrating a control method for a cooking apparatus according to yet another embodiment.

[0300] When the safety operation unit 163 is in the closed state and the safety switch SS is in the open state, the controller 30 can confirm whether the safety option is in the open state (600).

[0301] In step 600, if it is confirmed that the safety option is in the off state, the controller 30 can confirm whether any one of the heating operation units 130 has been changed to the on state (620).

[0302] In step 620, if it is confirmed that there is no heater that has changed to the on state, the controller 30 may execute step 620 again.

[0303] In step 620, if any one of the heating operation units 130 is changed to the open state, the heating switch HS corresponding to the heating operation unit that has been changed to the open state can be closed (621).

[0304] Furthermore, in step 620, if it is confirmed that any one of the heating operation units 130 has changed to the on state, the controller 30 can control the safety switch SS corresponding to the heating operation unit that has changed to the on state to be closed (622). Accordingly, power can be supplied to the heater 120 corresponding to the heating operation unit that has changed to the on state through the first power supply line L1 and the second power supply line L2. Accordingly, the heater 120 corresponding to the heating operation unit that has changed to the on state can be driven.

[0305] Subsequently, if the heating operation unit of another heater is changed to the on state (410), the heating switch corresponding to the other heating operation unit 130 that has been changed to the on state is closed, so that the other heater can be driven (411). In step 410, if the heating operation unit of another heater is not changed to the on state, the control can be terminated.

[0306] In step 600, if it is confirmed that the safety option is enabled, the controller 30 can confirm whether there is a driven heater among the one or more heaters included in the cooking device 10 (601).

[0307] In another embodiment, if the cooking device 10 does not have a safety option setting function, steps 600, 620, 621, and 622 can be omitted. In this case, if the cooking device 10 starts operating, the controller 30 can execute the commands first. Figure 12 Step 601 is shown.

[0308] In step 601, if a heater is in operation, step 610 can be executed. In step 610, if the heating operation unit 130 corresponding to another heater that is not in operation is turned on, the heating switch corresponding to the other heating operation unit 130 that has turned on is closed, thereby enabling the other heater to be driven (611). In step 610, if the heating operation unit of another heater is not turned on, control can be terminated.

[0309] In step 601, if it is confirmed that all heaters are not in operation, the controller 30 can confirm whether the safety operation unit 163 has changed from the off state to the on state (602).

[0310] In step 602, if it is confirmed that the safety operation unit 163 has not been changed to the on state, the controller 30 can confirm whether any one of the heating operation units 130 is in the on state (609).

[0311] In step 609, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 may then execute step 602.

[0312] In step 609, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may terminate control. In another embodiment, in step 609, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may terminate control after executing the second warning action described later.

[0313] In step 602, if it is confirmed that the safety operation unit 163 has changed to the on state, the controller 30 can confirm whether all heating operation units 130 are in the off state (603). In step 602, if it is confirmed that the safety operation unit 163 is in the on state, the controller 30 can illuminate the safety operation unit status display area 165.

[0314] In step 603, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 can control the closing of the safety switch SS (604).

[0315] In step 603, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 can change the safety operation unit 163 to the off state (607). If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the safety operation unit status display area 165. After executing step 607, the controller 30 can then execute step 601.

[0316] After performing step 604, the controller 30 can confirm whether any one of the heating operation units 130 has been changed to the on state (605).

[0317] In step 605, if it is confirmed that the heating operation unit 130 has not changed to the on state, the controller 30 can confirm whether the first standby time has elapsed (606). The first standby time can be set differently depending on the embodiment.

[0318] In step 606, if it is confirmed that the first standby time has not elapsed, the controller 30 may then execute step 605.

[0319] In step 606, if it is confirmed that the first standby time has elapsed, the controller 30 can change the safety operation unit 163 to the off state (607). Furthermore, the controller 30 can change the safety switch SS to the on state. If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the safety operation unit status display area 165. After executing step 607, the controller 30 can then execute step 601.

[0320] According to steps 602 to 607, after the safety operation unit 163 changes from the off state to the on state, if the heating operation unit 130 is not operated within a specified time (first standby time), the safety operation unit 163 automatically changes back to the off state. Through this control, even if the safety operation unit 163 changes to the on state, if the heating operation unit 130 is not operated within the specified time, the safety operation unit 163 returns to the off state, thus enabling the cooking equipment 10 to maintain a safer state.

[0321] In step 605, if the heating operation unit 130 is changed to the on state, the heating switch HS can be closed (608). Accordingly, power can be supplied to the heater 120 through the first power supply line L1 and the second power supply line L2, thereby driving the heater 120.

[0322] In other words, when the safety operation unit 163 is in the open state and the heating operation unit 130 is in the closed state, the controller 30 can control the safety switch SS to be closed.

[0323] With this control, the user can operate the heating operation unit 130 to drive the heater only when all heating operation units 130 are in the off state and the user changes the safety operation unit 163 to the on state.

[0324] In the action indicator light 160, such as Figure 4 or Figure 6 or Figure 7 or Figure 8In that configuration, since the heating switch HS is closed in step 608, the operation indicator light 160 can be illuminated. Based on this, the user can identify whether the heater 120 is activated or the heating operation unit 130 is in the on state.

[0325] In the action indicator light 160, such as Figure 5 or Figure 9 With that configuration, since the safety switch SS is closed in step 604, the action indicator light 160 can be illuminated. Based on this, the user can recognize that the safety function is activated.

[0326] After the heater is driven in step 608, step 610 can be executed. In step 610, if the heating operation unit 130 corresponding to another heater that is not being driven changes to an on state, the heating switch corresponding to the other heating operation unit 130 that has changed to an on state closes, thereby driving the other heater (611). If the heating operation unit of the other heater does not change to an on state in step 610, the control can be terminated.

[0327] Figure 13 This is a flowchart illustrating a control method for a cooking apparatus according to yet another embodiment.

[0328] When the safety operation unit 163 is in the closed state and the safety switch SS is in the open state, the controller 30 can confirm whether there is a driven heater (701) among the more than one heaters included in the cooking device 10.

[0329] In step 701, if a heater is in operation, step 711 can be executed. In step 711, if the heating operation unit 130 corresponding to another heater that is not in operation changes to an on state, the heating switch corresponding to the other heating operation unit 130 that has changed to an on state closes, thus enabling the other heater to be driven (712). In step 711, if the heating operation unit of another heater does not change to an on state, control can be terminated.

[0330] In step 701, if it is confirmed that all heaters are not in operation, the controller 30 can confirm whether the safety operation unit 163 has changed from the off state to the on state (702).

[0331] In step 702, if it is confirmed that the safety operation unit 163 has not been changed to the on state, the controller 30 can confirm whether any one of the heating operation units 130 is in the on state (710).

[0332] In step 710, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 may then execute step 702.

[0333] In step 710, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 can end the control.

[0334] In another embodiment, in step 710, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may end control after executing a warning action. If a warning action is executed, the controller 30 may control the image or text displayed on the display panel 150 to flash. As another example, if a warning action is executed, the controller 30 may control the output of a warning sound or warning voice through a speaker. As yet another example, if a warning action is executed, the controller 30 may control the flashing of the action indicator light 160.

[0335] In step 702, if it is confirmed that the safety operation unit 163 has changed to the open state, the controller 30 can confirm whether all heating operation units 130 are in the closed state (703).

[0336] In one embodiment, if it is confirmed in step 702 that the safety operation unit 163 is in the on state, the controller 30 may illuminate the safety operation unit status display area 165. In another embodiment, even if it is confirmed in step 702 that the safety operation unit 163 is in the on state, the controller 30 may keep the safety operation unit status display area 165 in the off state.

[0337] In step 702, even if the safety operation unit 163 is confirmed to be in the open state, the controller 30 can keep the safety switch SS in the open state.

[0338] In step 703, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 can confirm whether a predetermined first standby time (e.g., 10 seconds) has elapsed since the time point at which it was confirmed that any one of the heating operation units 130 is in the on state (706). The controller 30 can continue to execute step 703 until the first standby time has elapsed. The first standby time can be set differently depending on the embodiment.

[0339] If, during a predetermined first standby time elapsed from the time of confirmation until any of the heating operation units 130 are in the on state, the heating operation unit 130 does not change to the off state, the controller 30 can change the safety operation unit 163 to the off state (707). If the safety operation unit 163 changes to the off state, the controller 30 can turn off the safety operation unit status display area 165. After executing step 707, the controller 30 can then execute step 701.

[0340] According to steps 702, 703, 706, and 707, when the safety operation unit 163 changes from the closed state to the open state, if it is confirmed that any one of the heating operation units 130 is in the open state, the controller 30 can keep the safety operation unit 163 in the open state until a predetermined first standby time has elapsed.

[0341] In the above embodiment, if the heating operation unit 130, which is in the on state, has not been changed to the off state by the end of the first standby time, the safety operation unit 163 can be changed to the off state. Therefore, the user who wants to drive the heater needs to change the safety operation unit 163 back to the on state before operating the heating operation unit 130. Therefore, if all heaters are not driven and the heating operation unit 130 is in the on state, even if the user operates the safety operation unit 163, the heaters cannot be driven, thereby ensuring the safety of the cooking device 10.

[0342] In the above embodiment, if all heating operation units 130 are switched to the off state before the first standby time has elapsed, the safety operation unit 163 remains on, and step 704 can be executed. Therefore, when all heaters are not driven and the heating operation units 130 are on, if the user switches the heating operation units 130 to the off state within a specified time, i.e., the first standby time, the user can drive the heaters without having to perform the cumbersome operation of the safety operation unit 163.

[0343] In another embodiment, in step 703, if it is confirmed that any one of the heating operation units 130 is in the on state, the controller 30 may also immediately change the safety operation unit 163 to the off state.

[0344] In step 703, if it is confirmed that all heating operation units 130 are in the off state, the controller 30 can confirm whether any one of the heating operation units 130 has changed to the on state (704).

[0345] In step 704, if it is confirmed that the heating operation unit 130 has not changed to the on state, the controller 30 can confirm whether a predetermined second standby time (e.g., 30 seconds) has elapsed (705). The second standby time can be set differently depending on the embodiment.

[0346] In step 705, if it is confirmed that the second standby time has not elapsed, the controller 30 may then execute step 704.

[0347] In step 705, if it is confirmed that the second standby time has elapsed, the controller 30 can change the safety operation unit 163 to the off state (707). If the safety operation unit 163 is changed to the off state, the controller 30 can turn off the lights in the safety operation unit status display area 165. After executing step 707, the controller 30 can then execute step 701.

[0348] According to steps 704, 705, and 707, if the heating operation unit 130 is not operated within a specified time (the second standby time) after the safety operation unit 163 changes from the off state to the on state, the safety operation unit 163 automatically changes back to the off state. Through this control, even if the safety operation unit 163 changes back to the on state, if the heating operation unit 130 is not operated within the specified time, the safety operation unit 163 returns to the off state, thereby maintaining a safer cooking device 10.

[0349] In step 704, if the heating operation unit 130 is changed to the on state, the heating switch HS can be closed (708). Furthermore, in step 704, if it is confirmed that the heating operation unit 130 has changed to the on state, the controller 30 can control the closing of the safety switch SS (709). Accordingly, the heater 120 can be driven by supplying power to the heater 120 via the first power supply line L1 and the second power supply line L2.

[0350] In other words, when the safety operation unit 163 is in the open state and the heating operation unit 130 is in the closed state, if the heating operation unit 130 is changed to the open state, the controller 30 can control it to close the safety switch SS.

[0351] With this control, the user can operate the heating operation unit 130 to drive the heater only when all heating operation units 130 are in the off state and the user changes the safety operation unit 163 to the on state.

[0352] In one embodiment, in step 708, since the heating switch HS is closed, the operation indicator light 160 can be illuminated. Based on this, the user can identify that the heater 120 is activated or the heating operation unit 130 is in the on state.

[0353] In another embodiment, in step 709, since the safety switch SS is closed, the action indicator light 160 can be illuminated. Based on this, the user can recognize that the safety function is activated.

[0354] After driving the heater by performing steps 708 and 709, step 711 can be performed. In step 711, if the heating operation unit 130 corresponding to another heater that is not being driven changes to an on state, the heating switch corresponding to the other heating operation unit 130 that has changed to an on state closes, thus driving the other heater (712). If the heating operation unit of the other heater does not change to an on state in step 711, the control can be terminated.

[0355] Figure 14 This is a flowchart illustrating a control method for a cooking apparatus according to yet another embodiment.

[0356] In execution Figure 13 After steps 708 and 709, that is, after the heating switch HS and the safety switch SS are both closed, the controller 30 can confirm whether the heating operation unit 130, which is in the open state, has changed to the closed state (720).

[0357] If it is confirmed in step 720 that the heating operation unit 130 is in the on state, the controller 30 may then execute step 720.

[0358] In step 720, if the heating operation unit 130 is changed to the off state, the heating switch HS can be turned on (721). Furthermore, in step 720, if it is confirmed that the heating operation unit 130 has changed to the off state, the controller 30 can turn the safety switch SS on (722). Accordingly, both the heating switch HS and the safety switch SS can be turned on.

[0359] With both the heating switch HS and the safety switch SS open, the controller 30 can keep the safety operation unit 163 in the open state (723). When the safety operation unit 163 is kept in the open state, the safety operation unit status display area 165 can remain lit.

[0360] With the safety operation unit 163 in the open state, the controller 30 can confirm whether the heating operation unit 130 has changed from the closed state to the open state (724).

[0361] In step 724, if the heating operation unit 130 changes from the off state to the on state, the heating switch HS (708) can be closed. Furthermore, in step 724, if the heating operation unit 130 changes from the off state to the on state, the controller 30 can control it to close the safety switch SS (709). Accordingly, the heater 120 can be driven by supplying power to the heater 120 via the first power supply line L1 and the second power supply line L2.

[0362] In step 724, if it is confirmed that the heating operation unit 130 is in the off state, the controller 30 can confirm whether a predetermined third standby time (e.g., 60 seconds) has elapsed since the execution of steps 721 and 722 (725). The third standby time can be set differently depending on the embodiment.

[0363] In step 725, if it is confirmed that the third standby time has not elapsed, the controller 30 may execute step 723.

[0364] In step 725, if it is confirmed that the third standby time has elapsed, the controller 30 can change the safety operation unit 163 to the off state (726). In step 726, if the safety operation unit 163 is changed to the off state, the safety operation unit status display area 165 can be turned off.

[0365] according to Figure 14 In the illustrated embodiment, if the heating operation unit 130 is switched to the off state and the heater operation is interrupted during heater operation, the safety operation unit 163 will not immediately switch to the off state, but will remain on for a predetermined time, namely the third standby time. Accordingly, from the time when the heater operation is interrupted until the third standby time, the user can restart the heater simply by operating the heating operation unit 130, without needing to perform the cumbersome operation of the safety operation unit 163.

[0366] However, if the heating operation unit 130 has not been switched on by the time the heater's operation was interrupted, the safety operation unit 163 can be switched off. Therefore, after the third standby time, if the user wants to operate the heater, the safety operation unit 163 needs to be switched on again before operating the heating operation unit 130. This ensures the safety of the cooking appliance 10.

[0367] Figures 15 to 17 This is a diagram illustrating an exemplary process by which a user sets safety options for a cooking appliance according to an embodiment.

[0368] Reference Figure 15 Users can press or touch the setting operation unit 166 included in the display unit 150. If the user presses or touches the setting operation unit 166, a menu for setting the functions of the cooking equipment can be displayed in the second display area 152.

[0369] Each time the user presses or touches the setting operation unit 166, the menu displayed in the second display area 152 may be different. For example, if the user presses or touches the setting operation unit 166 a predetermined number of times (e.g., eight times), a security option setting menu (e.g., "CtOn") may be displayed in the second display area 152. While the security option setting menu (e.g., "CtOn") is displayed in the second display area 152, the user can set the security option to an on or off state by pressing or touching a preset setting change operation unit (e.g., the "1" key in the numeric input area 167).

[0370] For example, such as Figure 15 In that state, with the security option setting menu (e.g., CtOn) displayed in the second display area 152, if the user presses the "1" key in the numeric input area 167, then... Figure 16 In this way, a message indicating that the security option is enabled (e.g., "ON") is displayed in the first display area 151. Figure 16 With the first display area 151 displaying a message indicating that the security option is enabled (e.g., "ON"), if the user presses the "1" key in the numeric input area 167 again, then... Figure 17 In this way, a message indicating that the security option is off (e.g., "OFF") is displayed in the first display area 151. Figure 17 In such a state where the first display area 151 displays a message indicating that the security option is off (e.g., "OFF"), if the user presses the "1" key in the numeric input area 167 again, then... Figure 16 Then, in the first display area 151, a message indicating that the security option is enabled (e.g., "ON") will be displayed again.

[0371] When the first display area 151 is displayed as "ON" or "OFF" due to operation of the setting change operation unit (e.g., the "1" key in the numeric input area 167), the user can end the setting of the safety option by pressing or touching the setting operation unit 168. For example, when the first display area 151 displays "ON," pressing or touching the setting operation unit 168 will set the safety option of the cooking appliance to the "ON" state. Conversely, when the first display area 151 displays "OFF," pressing or touching the setting operation unit 168 will set the safety option of the cooking appliance to the "OFF" state.

[0372] Figures 18 to 20 This is a diagram illustrating an exemplary embodiment of a control panel for a user operating a cooking appliance.

[0373] In the case where the heater is not driven, such as Figure 3 As shown, the operation indicator light 160 and the safety operation unit status display area 165 can both be turned off. Furthermore, the safety operation unit 163 can remain off.

[0374] With all heating operation sections 131 to 135 and 220 in the off state and all heaters not activated, the user can press or touch the safety operation section 163. If the user changes the safety operation section 163 from the off state to the on state by pressing or touching it, then... Figure 18 As shown, the safety operation unit status display area 165 can be lit.

[0375] When the safety operation unit 163 is in the open state and all heating operation units 131 to 135, 220 are in the closed state, if the user rotates the first heating operation unit 131 to turn it on, the heater disposed in the first heating area 121 corresponding to the first heating operation unit 131 can be driven. At this time, if... Figure 19 As shown, the action indicator light 160 can be turned on.

[0376] When the user activates the safety function by pressing or touching the safety operation unit 163, and the heater located in the first heating area 121 is driven by rotating the first heating operation unit 131, if the user operates other heating operation units (132 to 135, 220), the other heaters corresponding to the operated heating operation unit can be driven immediately.

[0377] In one embodiment, when the safety operation unit 163 is in the off state and at least one of the heating operation units 131 to 135, 220 is in the on state, if the user presses or touches the safety operation unit 163, the controller 30 can keep the safety operation unit 163 in the on state from the time the user presses or touches the safety operation unit 163 until a first standby time has elapsed.

[0378] If the heating operation unit, which was in the on state, is changed to the off state between the time when the user presses or touches the safety operation unit 163 and the first standby time has elapsed, the user can operate the heating operation units 131 to 135, 220 to drive the heater without having to press or touch the safety operation unit 163 again.

[0379] If the heating operation unit, which is in the on state, has not changed to the off state by the time the user presses or touches the safety operation unit 163, the controller 30 can change the safety operation unit 163 to the off state. Therefore, the user who wants to drive the heater needs to press or touch the safety operation unit 163 again.

[0380] In one embodiment, when the safety operation unit 163 is in the off state and at least one of the heating operation units 131 to 135, 220 is in the on state, if the user presses or touches the safety operation unit 163, the safety operation unit status display area 165 can remain in the off state. If the user changes the heating operation unit from the on state to the off state before the first standby time has elapsed, the safety operation unit status display area 165 can be illuminated.

[0381] In another embodiment, when the safety operation unit 163 is in the off state and at least one of the heating operation units 131 to 135, 220 is in the on state, if the user presses or touches the safety operation unit 163, the controller 30 can immediately change the safety operation unit 163 to the off state. At this time, even if the user presses or touches the safety operation unit 163, the safety operation unit status display area 165 may not be illuminated.

[0382] In one embodiment, such as Figure 18 As shown, if the user does not perform any operation within the second standby time while the safety operation unit status display area 165 is lit, the controller 30 can change the safety operation unit 163 to the off state. Accordingly, the safety operation unit status display area 165 can also be turned off.

[0383] In another embodiment, such as Figure 18 As shown, if the user does not perform any operation within the second standby time when the safety operation status display area 165 is illuminated, the controller 30 may execute a warning action. If the warning action is executed, then... Figure 20 As shown, a warning message or warning sound is output through a speaker. Alternatively, if a warning action is performed, the action indicator light 160 may flash or the safety operation status display area 165 may flash. Alternatively, if a warning action is performed, a specific icon or text on the display panel 150 may flash. Alternatively, if a warning action is performed, a warning message or error code may be displayed on the display panel 150 and / or the warning message or error code may flash.

[0384] In one embodiment, such as Figure 19As shown, when the safety operation unit 163 is in the ON state, the first heating operation unit 131 is in the ON state, and only the heater corresponding to the first heating operation unit 131 is being driven, if the user changes the first heating operation unit 131 to the OFF state, the driving of the heater can be interrupted. The controller 30 can keep the safety operation unit 163 in the ON state until a third standby time has elapsed since the heater driving was interrupted. During the period when the safety operation unit 163 remains in the ON state, the safety operation unit status display area 165 can remain illuminated.

[0385] If heating operation units 131 to 135 and 220 are switched on before the third standby time has elapsed since the heater drive was interrupted, the heater can be driven. If heating operation units 131 to 135 and 220 are not switched on before the third standby time has elapsed since the heater drive was interrupted, the controller 30 can switch safety operation unit 163 to the off state. If safety operation unit 163 is switched off, the safety operation unit status display area 165 can be turned off.
