Description

[Technical field]

[0001] The present invention relates to a cooking device that heats and cooks food to be cooked. [Background technology]

[0002] Conventionally, there is a cooking device equipped with a heater for heating food to be cooked. In this type of cooking device, when the heating power of the heater is changed significantly, a change in the heating power state is notified to the user by voice in order to prevent the user from being surprised (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-008760 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a configuration in which changes in the heat status are notified only by voice, such as in the heating cooking device described in Patent Document 1, the voice may be missed, and when the user subsequently notices the change in status, there is a risk that the user will be surprised by the change in status or mistakenly believe that it is a malfunction or the like.

[0005] Furthermore, in a case where a single heater contains multiple burners, such as the heater of the cooking device described in Patent Document 1, when adjusting the heat, etc., the state may switch from one in which all burners are ignited to one in which only some burners are ignited and the other burners are extinguished.

[0006] However, the cooking device described in Patent Document 1 only issues a warning when the heat becomes too strong. Therefore, even if the fire is extinguished based on normal control, the user may be surprised by the extinguishing or mistakenly think that there is a malfunction.

[0007] The present invention has been made in consideration of the above points, and has an object to provide a cooking device that allows a user to accurately understand the state of a heater. [Means for solving the problem]

[0008] The cooking device of the present invention is A cooking device including a heater for heating food and a control device for controlling the heater, A display device is provided to display the state of the heater, The heater includes a first burner and a second burner, The control device independently performs ignition and extinguishing of each of the first burner and the second burner; The display device is characterized by including a first indicator that displays information regarding the ignition state and extinguishing state of the first burner while the ignition state or extinguishing state of the first burner continues, and a second indicator that is provided independently of the first indicator and displays information regarding the ignition state and extinguishing state of the second burner while the ignition state or extinguishing state of the second burner continues.

[0009] In this way, in the heating cooking device of the present invention, a display device that notifies information regarding the ignition state and extinguishing state of the corresponding burner is configured by a display device that displays information regarding the ignition state and extinguishing state of the corresponding burner while the burner remains in the ignition state or extinguishing state.

[0010] As a result, even if the user is unable to recognize the switch from one of the ignition state and the extinguishing state to the other, or the notification that occurs simultaneously with the switch, the user can accurately understand the state of the heater at that point in time simply by looking at the content that continues to be displayed on the display device after the switch, preventing the user from mistakenly believing that a malfunction has occurred.

[0011] In addition, the display device of this heating cooking device includes a first display device that displays information regarding the ignition state and extinguishing state of the first burner, and a second display device that is provided independently of the first display device and displays information regarding the ignition state and extinguishing state of the second burner.

[0012] As a result, when only one burner goes into an extinguished state, only the display content of the one display corresponding to that burner changes. Therefore, in this state, the user can accurately understand whether the extinguishing of one burner is based on normal control by comparing the display content of the one display with the display content of the other display corresponding to the other burner that is in the ignition state (i.e., based on whether they match).

[0013] In addition, in the heating and cooking device of the present invention, The first indicator is configured as a first indicator light that is turned on while the first burner is in an ignition state and turned off while the first burner is in an extinguished state; The second indicator is preferably configured as a second indicator light that is turned on while the second burner is in an ignition state and is turned off while the second burner is in an extinguished state.

[0014] When an indicator light is used as the indicator that constitutes the display device, the indicator light can be configured in this manner so that it is lit when the corresponding burner is in the ignition state and is turned off when the burner is in the extinguished state, allowing the user to easily understand the state of the heater.

[0015] In addition, in the heating and cooking device of the present invention, It is preferable that the device further comprises an audio alarm device which, when the state of the heater changes, issues an audio notification of the change in state.

[0016] In this way, in addition to the visual alert by the display device when the ignition or extinguishing state continues, an audio alert is provided by the sound alert device when the state changes, allowing the user to easily know when the heater state has changed, further preventing the user from mistakenly thinking that a malfunction has occurred.

[0017] In addition, in the heating and cooking device of the present invention, The control device independently adjusts the flame power of each of the first burner and the second burner, The information displayed by the first display unit includes a flame power adjustment status of the first burner, The information displayed by the second display preferably includes a flame power adjustment status of the second burner.

[0018] In this way, by notifying the user of the flame adjustment status in addition to the ignition status and extinguishing status, the user can understand the status of the heater in detail, which further prevents the user from mistakenly thinking that a malfunction has occurred.

[0019] In addition, in the heating and cooking device of the present invention, It is preferable that the control device automatically and independently executes ignition and extinguishing of each of the first burner and the second burner based on the cooking contents of the food to be cooked.

[0020] In so-called automatic cooking, the ignition state and the extinguishing state are switched regardless of the user's intention. Therefore, in automatic cooking, it is difficult for the user to recognize the switching, and it is easy for a malfunction to occur in which the user mistakenly believes that a malfunction has occurred. Therefore, in a heating cooking device that performs such automatic cooking, it is preferable to apply the present invention so that the user can easily understand the state of the heater, thereby preventing such a malfunction.

[0021] In addition, in the heating and cooking device of the present invention, The heater is preferably a stove burner in which the first burner and the second burner are arranged adjacent to each other in the vertical direction.

[0022] When the heater is such a stove burner, the user can directly see the state of the stove burner. This allows the user to directly compare the state of the stove burner with the state of the display device. Therefore, when the present invention is applied to such a stove burner, the user can easily understand the state of the heater.

[0023] In addition, in the heating and cooking device of the present invention, It is preferable that the positional relationship between the first indicator and the second indicator corresponds to the positional relationship between the first burner and the second burner.

[0024] In this way, by making the positional relationship between the display and the burner that constitute the display device correspond to each other, the user can easily judge whether the state of the burner matches the state of the display device, and thus the user can easily understand the state of the heater.

[Diagram 3] FIG. 2 is a vertical cross-sectional view showing the internal structure of the stove burner of the stove of FIG. 1. [Figure 4] FIG. 2 is an explanatory diagram showing an example of a lighting state of an indicator light of the stove in FIG. 1 . [Diagram 5] 4 is a flowchart showing the process executed by the stove in FIG. 1 when the flame power of the burner is changed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, a stove S (heat cooking device) according to an embodiment will be described with reference to Figs. 1 to 5.

[0027] As described below, this stove S is a built-in stove and is equipped with a number of stove burners 3 arranged on the top plate 2 as a heater, as well as a grill 4 that can be freely pulled out from the front (see Figure 1, etc.).

[0028] However, the cooking device of the present invention is not limited to such a configuration, and may be any device that includes a heater for heating the food to be cooked and a control device for controlling the heater. Therefore, for example, the cooking device may be a free-standing stove instead of a built-in stove.

[0029] [Schematic configuration] First, the schematic configuration of the stove S will be described with reference to Figs.

[0030] As shown in Fig. 1, stove S is a built-in stove that is installed in a countertop (not shown) of a system kitchen. Stove S is equipped with stove body 1 that is installed by dropping it into an opening in the countertop, and a top plate 2 that is placed on the countertop so as to cover the upper surface of stove body 1.

[0031] The stove body 1 is exposed from the top plate 2 and has three stove burners 3 (heaters), two at the front and one at the back when installed, a grill 4 inside, and a grill door 5 in the central part of the front for opening and closing the front opening of the grill 4.

[0032] In addition, the stove body 1 has operation panels 6 for operating the stove burner 3 and grill 4, on either side of the grill door 5 on the front, and inside it, behind the operation panels 6, there is a flame adjustment device 7 (not shown in Figure 1, see Figure 2) composed of valves etc. for controlling the stove burner 3, grill 4 etc., and a control device 8 composed of a control board.

[0033] Of the three burners 3, the two burners on the front side are large-power burners and are configured as a parent-child burner, which will be described later. The one burner on the back side is a small-power burner.

[0034] On the operation panel 6, a stove operation button 3w and a grill operation button 4w are arranged.

[0035] The tabletop 2 also has display devices 9 for displaying the state of the two stove burners 3 at positions near the front side of the two stove burners 3 at the front side when the tabletop 2 is installed.

[0036] The number and position of the display devices of the present invention are not limited to this configuration and may be set as appropriate. For example, when there is only one heater (e.g., a parent and child burner) whose status should be displayed, only one display device may be provided. The display device may be located on the front panel or the like. A mobile terminal linked to the cooking device may act as the display device, and the display may be displayed on the screen of the mobile terminal or the like.

[0037] 1, but as shown in FIG 2, the stove S has a gas supply passage 10 that supplies fuel gas to the stove burner 3. The gas supply passage 10 also supplies fuel gas to the grill 4.

[0038] [Composition of stove burner, flame adjustment device and control device] Next, the two large-power burners on the front side of the stove burner 3 of the stove S, and the configuration of the heat adjustment device 7 and the control device 8 for controlling the large-power burners will be described in detail with reference to Figures 2 and 3. In the following, the large-power burners will be simply referred to as stove burners 3.

[0039] As described in detail below, the stove burner 3 is configured as a so-called parent-child burner, consisting of two burners: a parent burner 3a (first burner) and a child burner 3b (second burner) arranged adjacent to and below the parent burner 3a.

[0040] As shown in Figures 2 and 3, the stove burner 3 comprises a parent burner mixing tube 30 and a child burner mixing tube 31, a burner body 32 connected to the downstream ends of the parent burner mixing tube 30 and the child burner mixing tube 31, a cylindrical burner head 33 placed on the burner body 32, an annular burner cap 34 placed on the burner head 33, and a temperature sensor 35 arranged to pass through the burner head 33 and the burner cap 34.

[0041] The parent burner mixing tube 30 and the child burner mixing tube 31 are formed by airtightly connecting an upper member forming its upper half and a lower member forming its lower half to each other at their outer peripheral edges using crimping or the like.

[0042] The parent burner mixing tube 30 and the child burner mixing tube 31 take in the fuel gas ejected from a gas nozzle (not shown) together with primary air, and generate a mixed gas of the fuel gas and primary air therein, which is then supplied to the flame holes of the parent burner 3a and the child burner 3b, which will be described later.

[0043] The burner body 32 is configured as a triple cylinder including an outer cylindrical portion 32a located on the outermost side, an intermediate cylindrical portion 32b arranged inside the outer cylindrical portion 32a, and an inner cylindrical portion 32c arranged inside the intermediate cylindrical portion 32b. In this embodiment, the burner body 32 is made of sheet metal, but may be made of casting or die casting.

[0044] The space between the outer cylindrical portion 32a and the intermediate cylindrical portion 32b is the internal space of the child burner 3b, and is connected to the child burner mixing tube 31. The space between the intermediate cylindrical portion 32b and the inner cylindrical portion 32c is the internal space of the parent burner 3a, and is connected to the parent burner mixing tube 30.

[0045] The burner body 32 also has an annular mounting portion 32d (the bottom of the flame hole of the sub burner 3b) on the upper edge of the outer cylindrical portion 32a. The burner head 33 is mounted on the mounting portion 32d.

[0046] The burner head 33 has a ring-shaped first annular portion 33a, a first cylindrical portion 33b extending downward from the inner peripheral edge of the first annular portion 33a, a second cylindrical portion 33c extending upward from the outer peripheral edge of the first annular portion 33a, and a target portion 33d protruding toward the outer periphery from a part of the upper edge of the second cylindrical portion 33c and facing an ignition electrode (not shown).

[0047] In this embodiment, the burner head 33 is made of die-cast aluminum, but it may be made of sheet metal such as iron or stainless steel, or may be made of castings such as brass.

[0048] The burner head 33 is seated on the mounting portion 32d of the burner body 32 with the lower surface of the first annular portion 33a. At this time, the first cylindrical portion 33b is fitted into the intermediate cylindrical portion 32b of the burner body 32 so as to abut against the inner circumferential surface of the intermediate cylindrical portion 32b.

[0049] Here, the first annular portion 33a has, on its lower surface, a number of first grooves 33e that are spaced apart in the circumferential direction and extend radially to the outer periphery of the first annular portion 33a. Therefore, when the burner head 33 is placed on the burner body 32, the first grooves 33e of the burner head 33 and the placement portion 32d of the burner body 32 form the burner holes of the sub burners 3b.

[0050] From the flame holes of the sub burner 3b, the mixed gas supplied from the sub burner mixing tube 31 through the aforementioned internal space is ejected. Therefore, when the sub burner 3b is in use, a large number of flames are formed between the burner head 33 and the burner body 32 along their peripheral surfaces.

[0051] The second cylindrical portion 33c has a number of second grooves 33f that are spaced apart in the circumferential direction and extend radially to the outer periphery so as to penetrate the second cylindrical portion 33c. The second grooves 33f, together with a second annular portion 34a of a burner cap 34 described later, form the burner holes of the parent burner 3a.

[0052] The burner cap 34 has an annular second annular portion 34a and a third cylindrical portion 34b extending downward from the inner circumferential edge of the second annular portion 34a.

[0053] In this embodiment, the burner cap 34 is made of die-cast aluminum, but it may be made of sheet metal such as iron or stainless steel, or may be made of castings such as brass.

[0054] The burner cap 34 is seated on the upper surface side of the second cylindrical portion 33c of the burner head 33 with the lower surface of the second annular portion 34a. At this time, the third cylindrical portion 34b is fitted into the inner cylindrical portion 32c of the burner body 32 so as to abut against the inner peripheral surface of the inner cylindrical portion 32c.

[0055] As described above, the second cylindrical portion 33c of the burner head 33 has a large number of second grooves 33f that are spaced apart in the circumferential direction and extend radially to the outer periphery so as to penetrate the second cylindrical portion 33c. Therefore, when the burner cap 34 is placed on the burner head 33, the second grooves 33f of the burner head 33 and the upper surface of the second annular portion 34a of the burner cap 34 form the burner hole of the parent burner 3a.

[0056] The mixed gas supplied from the parent burner mixing tube 30 through the above-mentioned internal space is ejected from the flame holes of the parent burner 3a. Therefore, when the parent burner 3a is in use, a large number of flames are formed between the burner cap 34 and the burner head 33 along their peripheral surfaces.

[0057] In the stove burner 3, the total opening area of ​​the flame holes of the parent burner 3a is configured to be larger than the total opening area of ​​the flame holes of the child burners 3b. Therefore, the maximum heating power of the parent burner 3a is larger than the maximum heating power of the child burners 3b.

[0058] The tip of temperature sensor 35 protrudes upward beyond burner cap 34. Temperature sensor 35 abuts at its tip against the bottom surface of a cooking vessel (pot, frying pan, etc.) to detect the temperature of the cooking vessel.

[0059] As shown in FIG. 2, the flame power adjustment device 7 adjusts the amount of fuel gas supplied to the stove burner 3 via the gas supply path 10, thereby controlling the switching between ignition and extinguishing of the stove burner 3 (specifically, the parent burner 3a and the child burner 3b) and the degree of flame power.

[0060] The flame power adjustment device 7 includes a manual adjustment unit 70 for manually controlling the stove burner 3, and an automatic adjustment unit 71 for automatically controlling the stove burner 3 during automatic cooking, etc. The manual adjustment unit 70 and the automatic adjustment unit 71 are disposed in series in the gas supply path 10.

[0061] The manual adjustment unit 70 and the automatic adjustment unit 71 are configured using a known structure, such as an electrically operated flow rate adjustment valve having a valve body driven by a motor, or an electromagnetic opening / closing valve that is switched on and off by an electromagnetic solenoid.

[0062] The control device 8 outputs a control signal to the automatic adjustment unit 71 based on the temperature detected by the temperature sensor 35 and the like, and also outputs a notification signal to the display device 9 and speaker 11, which will be described later.

[0063] Here, the operation panel 6 (see FIG. 1) is provided with switches for automatic cooking, such as a water boiling switch, a noodle boiling switch, a rice cooking switch, and the like, all of which are not shown.

[0064] When any of these automatic cooking switches is turned on, the control device 8 controls the automatic adjustment section 71 of the flame power adjustment device 7 based on the detected temperature of the temperature sensor 35, etc., to automatically adjust the flame power of the stove burner 3 (i.e., the amount of fuel gas supplied, and the ignition and extinguishing of the parent burner 3a and child burner 3b).

[0065] On the other hand, when none of these automatic cooking switches are turned on, the control device 8 drives the manual adjustment section 70 of the flame adjustment device 7 in response to the user's operation of the stove control 3w located on the operation panel 6, thereby adjusting the flame of the stove burner 3 (i.e., the amount of fuel gas supplied, and the ignition and extinguishing of the parent burner 3a and child burner 3b).

[0066] In this embodiment, the manual adjustment unit 70 of the heat adjustment device 7 includes devices that perform electrical control such as a motor as described above, and is therefore driven based on a signal from the control device 8. However, for example, if the manual adjustment unit is made up of only devices with a mechanical structure that do not require electrical control, the manual adjustment unit may be configured to be directly controlled by the user's operation of the stove operator without going through the control device (i.e., electrical control).

[0067] The manual adjustment unit 70 and the automatic adjustment unit 71 adjust the fire power independently for the parent burner 3a and the child burner 3b.

[0068] In addition, when the heat of the stove burner 3 is changed during automatic cooking, the control device 8 controls the speaker 11 (sound notification device) to notify the user of the change in heat by sound (including not only voice but also electronic sounds such as chimes and buzzers). The speaker 11 may be provided in the stove S itself, or in an external device such as a mobile terminal used by the user.

[0069] [Display device configuration] Next, the configuration of the display device 9 of the stove S will be described in detail with reference to Figs.

[0070] As shown in FIG. 1, the display device 9 is provided in a position near the front of each of the three stove burners 3, corresponding to each of the two stove burners 3 at the front that are configured as high-power burners (so-called parent and child burners).

[0071] The display device 9 is composed of a first indicator light 90 (first display) that displays information regarding ignition, extinguishing, and flame power of the parent burner 3a, and a second indicator light 91 (second display) that is provided independently of the first indicator light 90 and displays information regarding ignition, extinguishing, and flame power of the child burner 3b.

[0072] In this embodiment, the period during which the display continues is the period until each of the states of ignition, extinguishing, and flame strength changes.

[0073] The first indicator lamp 90 is configured by arranging three lamps in a row, each shaped like a flame. Each lamp is configured to be freely switched between a lit state and an unlit state independently of the others. The first indicator lamp 90 thus configured has all lamps in an unlit state while the corresponding parent burner 3a continues to be in an extinguished state, and any one of the lamps in the first indicator lamp 90 is in a lit state while the parent burner 3a continues to be in an ignited state.

[0074] The number of lamps of the first indicator lamp 90 that are turned on when the parent burner 3a is ignited varies depending on the degree of heat of the parent burner 3a. Specifically, when the heat of the parent burner 3a is high, all lamps are turned on, when it is medium, two lamps are turned on, and when it is low, only one lamp is turned on.

[0075] The second indicator lamp 91, like the first indicator lamp 90, is configured with two lamps arranged in a horizontal row, each shaped like a flame. Each lamp is configured to be freely switched between a lit state and an unlit state independently of the other lamps. The second indicator lamp 91 configured in this way has all lamps in an unlit state while the corresponding child burner 3b continues to be in an extinguished state, and any one of the lamps is in a lit state while the child burner 3b continues to be in an ignited state.

[0076] The number of lamps of the second indicator lamp 91 that are turned on when the child burner 3b is ignited varies depending on the degree of heat of the child burner 3b. Specifically, when the heat of the child burner 3b is high, all the lamps are turned on, and when the heat of the child burner 3b is low, only one lamp is turned on.

[0077] The first indicator light 90 and the second indicator light 91 are arranged so as to correspond to the relative arrangement of the parent burner 3a and the child burner 3b. Specifically, the child burner 3b is located below the parent burner 3a, so the second indicator light 91 is arranged in front of the first indicator light 90 (i.e., in a position that a user standing in front of the child burner 3b feels as if it is below).

[0078] In the display device 9 configured in this manner, as shown in FIG. 4, the first indicator light 90 and the second indicator light 91 are turned on and off independently depending on whether the parent burner 3a and child burner 3b of the stove burner 3 are in the ignition state or the extinguished state and the degree of flame strength.

[0079] Specifically, for example, as shown in FIG. 4, when the stove burner 3 ignites both the parent burner 3a and the child burner 3b and reaches a high flame state, all of the lamps constituting the first indicator light 90 and all of the lamps constituting the second indicator light 91 are lit.

[0080] In addition, when the stove burner 3 ignites the parent burner 3a and extinguishes the child burner 3b, resulting in a medium flame state, all of the lamps that make up the first indicator light 90 are lit, and all of the lamps that make up the second indicator light 91 are turned off.

[0081] In addition, when the stove burner 3 turns off the parent burner 3a and ignites the child burner 3b, resulting in a low flame state, all of the lamps that make up the first indicator light 90 are turned off and all of the lamps that make up the second indicator light 91 are turned on.

[0082] In addition, when the stove burner 3 extinguishes both the parent burner 3a and the child burner 3b and enters a fully extinguished state, all of the lamps that make up the first indicator light 90 and all of the lamps that make up the second indicator light 91 are turned off.

[0083] In the above explanation, for ease of understanding, a case has been described in which all of the lamps included in the first indicator lamp 90 are turned on or off uniformly, and all of the lamps included in the second indicator lamp 91 are turned on or off uniformly. However, since each lamp can be turned on or off independently, the state of the stove burner 3 can be divided into more detailed states (for example, dividing medium heat into strong medium heat and weak medium heat), and the number of lit lamps can be changed accordingly.

[0084] [Processing when the stove burner status changes] Next, with reference to Figs. 1 and 5, a detailed description will be given of the processing executed by the control device 8 and the display device 9 when the state of the stove burner 3 changes in the case of automatic cooking.

[0085] In this process, first, the control device 8 judges whether or not the ignition of the stove burner 3 has been recognized (FIG. 5 / STEP 10).

[0086] Specifically, when the control device 8 recognizes an ignition instruction from the user based on the operation of the stove operator 3w arranged on the operation panel 6, it determines whether or not the gas supply has been started by the manual adjustment unit 70 and whether the stove burner 3 has been ignited by the ignition electrode (not shown).

[0087] If ignition is not recognized (NO in STEP 10), the process returns to STEP 10 and the determination is made again. This process is repeated at a predetermined control period.

[0088] On the other hand, when ignition is recognized (YES in STEP 10), the control device 8 determines whether or not automatic cooking has started (FIG. 5 / STEP 11).

[0089] Specifically, the control device 8 determines whether or not any of the switches for automatic cooking has been turned on.

[0090] If it is not recognized that automatic cooking has started (NO in STEP 11), the process returns to STEP 11 and the determination is made again. This process is repeated at a predetermined control period.

[0091] On the other hand, when it is recognized that automatic cooking has started (YES in STEP 11), automatic cooking is started according to a predetermined program.

[0092] Specifically, the control device 8 automatically and independently ignites and extinguishes each of the parent burner 3a and the child burner 3b in response to a predetermined elapsed time and temperature change for the selected automatic cooking switch (i.e., the cooking content for the food to be cooked).

[0093] After automatic cooking has started, the control device 8 recognizes the state of the parent burner 3a, and the display device 9 changes the state of the first indicator light 90 according to the recognized state of the parent burner 3a (FIG. 5 / STEP 12).

[0094] Specifically, as described above, the control device 8 recognizes whether the parent burner 3a is in an ignition state or an extinguished state and the degree of flame strength based on the operating status of the automatic adjustment unit 71, and switches the number of lamps that make up the first indicator light 90 on and off depending on the recognized content.

[0095] Next, the control device 8 recognizes the state of the sub burner 3b, and the display device 9 changes the state of the second indicator light 91 according to the recognized state of the sub burner 3b (FIG. 5 / STEP 13).

[0096] Specifically, as described above, the control device 8 recognizes whether the sub burner 3b is in an ignition state or an extinguished state and the degree of flame strength based on the operating status of the automatic adjustment unit 71, and switches the number of lamps that make up the second indicator light 91 on and off depending on the recognized content.

[0097] Next, the control device 8 notifies the user of the change in state of the burner 3 by sound via the speaker 11 (FIG. 5 / STEP 14).

[0098] Next, the control device 8 judges whether the automatic cooking is completed or not (FIG. 5 / STEP 15).

[0099] If the automatic cooking has not been completed (NO in STEP 15), the process returns to STEP 12, and the processes from STEP 12 onwards are executed again.

[0100] On the other hand, if the automatic cooking has ended (YES in STEP 15), the control device 8 turns off the burner 3 and turns off the display device 9, and ends the current process.

[0101] As described above, the stove S is equipped with a display device 9 that notifies information regarding the ignition state and extinguishing state of the corresponding burner by a first indicator light 90 and a second indicator light 91 that display information while the corresponding burner remains ignited or extinguished.

[0102] As a result, even if the user is unable to recognize the switch from one of the ignition state and the extinguishing state to the other, or the audio notification that occurs simultaneously with the switch, the user can accurately understand the state of the burner 3 at that point in time simply by looking at the content that continues to be displayed on the display device 9 after the switch, preventing the user from mistakenly believing that a malfunction has occurred.

[0103] The stove S also includes a first indicator light 90 that displays information regarding the ignition state and extinguishing state of the parent burner 3a, and a second indicator light 91 that is provided independently of the first indicator light 90 and displays information regarding the ignition state and extinguishing state of the child burner 3b.

[0104] As a result, when only one of the parent burner 3a and the child burner 3b goes into an extinguished state, only the display content of one of the first indicator lamp 90 and the second indicator lamp 91 corresponding to that burner changes. Therefore, in that state, the user can compare the display content of that one indicator lamp with the display content of the other indicator lamp corresponding to the other burner that is in the ignition state (i.e., based on whether they match) and accurately determine whether the extinguishing of one burner is based on normal control.

[0105] [Other embodiments] Although the illustrated embodiment has been described above, the present invention is not limited to this embodiment.

[0106] For example, in the above embodiment, a parent-child burner in which a parent burner 3a and a child burner 3b are arranged adjacent to each other vertically is adopted as the heater. This is because, when the heater is such a stove burner, the user can visually confirm the state of the stove burner itself, and can directly compare the state of the stove burner with the state of the display device, and can easily understand the state of the heater.

[0107] However, the heater of the present invention is not limited to such a configuration, and may be any heater capable of heating food and including a first burner and a second burner that are independently ignited and extinguished. For example, instead of a stove burner, it may be a double-sided grill consisting of an upper burner and a lower burner.

[0108] In the above embodiment, the display device 9 is composed of a first indicator lamp 90 composed of three lamps and a second indicator lamp 91 composed of two lamps. Each of these lamps is turned on and off depending on the degree of heat of the corresponding parent burner 3a or child burner 3b. This is to allow the user to understand the state of the heater in detail and to further prevent the user from mistaking that a malfunction has occurred.

[0109] However, the display device of the present invention is not limited to such a configuration, and may include a first indicator and a second indicator, each of which has at least one lamp.

[0110] In addition, the degree of fire power does not necessarily have to be indicated. For example, in the configuration of this embodiment, all the lamps constituting the first indicator light 90 or all the lamps constituting the second indicator light 91 may be configured to be turned on and off uniformly in response to the ignition and extinguishing of the parent burner 3a or the child burner 3b.

[0111] The method of indication does not have to be the turning on and off of the indicator lamp, but may be, for example, a display using text or a change in color.

[0112] In the above embodiment, the shape of the lamp is a shape that imitates a flame, but it may be a shape that imitates a burner. Specifically, two annular lamps of different sizes may be arranged concentrically, with the larger lamp corresponding to the parent burner and the smaller lamp corresponding to the child burner. Furthermore, the degree of fire power may be indicated by a change in color.

[0113] In the above embodiment, the first indicator light 90 and the second indicator light 91 of the display device 9 are arranged so as to correspond to the arrangement relationship between the parent burner 3a and the child burner 3b. This is to allow the user to easily determine whether the state of the burner and the state of the display device match, and to easily understand the state of the heater.

[0114] However, the display device of the present invention is not limited to such a configuration, and therefore the positional relationship between the first display unit and the second display unit included in the display device may be set appropriately.

[0115] In addition, in the above embodiment, when the state of the stove burner 3 changes, the display on the display device 9 is changed according to the nature of the change, and an audio notification indicating the nature of the change is given by a speaker (not shown).

[0116] This is because, in addition to providing a visual alert via the display device 9 when the ignition or extinguishing state continues, an auditory alert via the speaker is provided when the state changes, allowing the user to easily know when the heater state has changed, thereby further preventing the user from mistakenly believing that a malfunction or the like has occurred.

[0117] However, the present invention is not limited to such a configuration, and instead of audio notification, electronic sounds such as chimes and buzzers may be used to notify the user. Furthermore, audio notification may be omitted. In addition, the audio notification device may be omitted.

[0118] In the above embodiment, the configuration is described in which the display contents of the first indicator light 90 and the second indicator light 91 are switched during automatic cooking. As described above, in automatic cooking, the ignition state and the extinguishing state are switched regardless of the user's intention. Therefore, it is difficult for the user to recognize the switching, and a malfunction may occur in which the user mistakenly believes that a malfunction or the like has occurred.

[0119] However, the display device of the cooking device of the present invention is not limited to such a configuration, and may be configured so that the display content can be switched even during manual cooking. [Explanation of symbols]
