Description

[Technical Field]

[0001] The present invention relates to a cooking device. [Background technology]

[0002] A conventional cooking device is disclosed in Patent Document 1. This cooking device includes a heating unit, a gas supply path, a supply amount adjusting unit, and a control unit.

[0003] The heating unit burns fuel gas to heat food. The gas supply path supplies fuel gas to the heating unit. The supply amount adjustment unit is provided in the gas supply path and adjusts the amount of fuel gas supplied to the heating unit. More specifically, the supply amount adjustment unit has a switching valve, a normal supply path, an energy-saving supply path, and a throttle valve. The switching valve can switch between connecting the gas supply path with the normal supply path and connecting the gas supply path with the energy-saving supply path. The throttle valve is provided in the energy-saving supply path and adjusts the flow rate of fuel gas flowing through the energy-saving supply path.

[0004] The control unit can control the supply amount adjustment unit. This allows the control unit to selectively execute a first operating state and a second operating state. Specifically, in the first operating state, the gas supply path and the normal supply path are connected by the switching valve, and fuel gas is supplied from the gas supply path to the heating unit via the normal supply path. On the other hand, in the second operating state, the gas supply path and the energy-saving supply path are connected by the switching valve, and fuel gas is supplied from the gas supply path to the heating unit via the energy-saving supply path. Here, in the second operating state, the overall amount of fuel gas supplied to the heating unit, including the maximum amount of fuel gas supplied to the heating unit, is reduced compared to the first operating state.

[0005] Thus, in this cooking device, the heating power of the heating unit is at normal strength in the first operating state, while the heating power of the heating unit is weaker than in the first operating state in the second operating state. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-138570 Summary of the Invention [Problem to be solved by the invention]

[0007] In recent years, there has been proposed a cooking device capable of executing an automatic cooking mode in which the heating power of the heating unit is automatically changed while the food is being cooked. Therefore, in the conventional cooking device, it is conceivable to execute the automatic cooking mode in the first operating state, or in the second operating state.

[0008] However, in the conventional cooking device described above, the amount of fuel gas supplied to the heating unit in the second operating state is smaller than that in the first operating state, and the heating power of the heating unit in the second operating state is weaker than that in the first operating state. As a result, when the automatic cooking mode is executed in the second operating state, the heating power of the heating unit is more likely to be insufficient than when the automatic cooking mode is executed in the first operating state. As a result, with this cooking device, there is a risk of large variations in the results of automatic cooking when the automatic cooking mode is executed in the first operating state and when the automatic cooking mode is executed in the second operating state.

[0009] The present invention has been made in consideration of the above-mentioned conventional situation, and has as its object to provide a heating cooker that can selectively execute a first operating state and a second operating state in which the maximum supply amount of fuel gas supplied to the heating section is different, while realizing high-quality automatic cooking. [Means for solving the problem]

[0010] The cooking device of the present invention comprises: a heating unit that burns fuel gas to heat food; a gas supply path for supplying the fuel gas to the heating unit; a supply amount adjusting unit that is provided in the gas supply path and adjusts the supply amount of the fuel gas that is supplied to the heating unit; a selection unit that allows a user to select an automatic cooking mode in which the food to be cooked is automatically cooked based on an automatic cooking menu while automatically changing the supply amount to the heating unit; a control unit capable of controlling the supply amount adjusting unit; a storage unit that stores a plurality of supply amounts to the heating unit in the automatic cooking mode as automatic cooking supply amounts; the control unit is capable of selectively executing a first operating state in which the maximum supply amount to the heating unit is a first maximum supply amount, and a second operating state in which the maximum supply amount to the heating unit is a second maximum supply amount that is smaller than the first maximum supply amount, The control unit is capable of executing the automatic cooking mode based on the user's selection in the first operating state or the second operating state, In the automatic cooking mode, the control unit can automatically change the supply amount to the heating unit based on the automatic cooking supply amount regardless of whether the first operating state or the second operating state is being executed, Each of the automatic cooking supply amounts is smaller than the first maximum supply amount.

[0011] In the cooking device of the present invention, the control unit can selectively execute a first operating state and a second operating state. Here, the second maximum supply amount in the second operating state is smaller than the first maximum supply amount in the first operating state. Therefore, in the second operating state, the maximum heating power of the heating unit is smaller than in the first operating state.

[0012] In this cooking appliance, when the user selects the automatic cooking mode, the control unit executes the automatic cooking mode. In the automatic cooking mode, the control unit automatically changes the supply amount to the heating unit based on multiple automatic cooking supply amounts stored in the memory unit, regardless of whether the first operating state or the second operating state is being executed. Here, each automatic cooking supply amount is less than the first maximum supply amount. Therefore, in the automatic cooking mode, the food to be cooked is heated at a heating power lower than the maximum heating power of the heating unit in the first operating state.

[0013] Thus, in this heating cooker, whether the control unit executes the automatic cooking mode in the first operating state or the control unit executes the automatic cooking mode in the second operating state, variations in the results of automatic cooking due to insufficient heating power in the heating unit are unlikely to occur.

[0014] Therefore, the cooking device of the present invention can selectively execute a first operating state and a second operating state in which the maximum supply amounts of fuel gas supplied to the heating section differ, and can achieve high-quality automatic cooking.

[0015] The memory unit may store a first control table in which the supply amount to the heating unit in the first operating state is allocated to multiple stages. Furthermore, in the first operating state, the user may be able to change the supply amount to the heating unit in stages based on the first control table. The first control table preferably includes a first maximum supply amount and each automatic cooking supply amount.

[0016] In this case, the user can use the automatic cooking supply amounts used in the automatic cooking mode in the first operating state as well. This allows the user to memorize the timing at which the automatic cooking supply amounts are automatically changed in the automatic cooking mode, for example, and reproduce that timing in the first operating state. This makes the cooking appliance more convenient.

[0017] The memory unit may store a second control table in which the supply amount to the heating unit in the second operating state is allocated to multiple stages. Furthermore, in the second operating state, the user may be able to change the supply amount to the heating unit in stages based on the second control table. The second control table preferably includes a second maximum supply amount and each automatic cooking supply amount.

[0018] In this case, the user can use the automatic cooking supply amounts used in the automatic cooking mode in the second operating state as well, thereby improving the convenience of this cooking device.

[0019] The memory unit may store a first control table in which the supply amount to the heating unit in the first operating state is allocated to multiple levels, a second control table in which the supply amount to the heating unit in the second operating state is allocated to multiple levels, and an automatic cooking control table in which each automatic cooking supply amount is set. The first control table may include a first maximum supply amount and each automatic cooking supply amount. In the first operating state, the user may be able to change the supply amount to the heating unit in stages based on the first control table. In the second operating state, the user may be able to change the supply amount to the heating unit in stages based on the second control table. When executing the automatic cooking mode at least in the second operating state, the control unit may automatically change the supply amount to the heating unit based on the automatic cooking control table. The supply amount to the heating unit allocated to multiple levels in the second control table preferably includes the second maximum supply amount but is different from at least one of the automatic cooking supply amounts.

[0020] In this case, it is not necessary to include all of the automatic cooking supply amounts in the second control table, which makes it possible to more appropriately allocate the supply amounts to the heating units in the second operating state than when all of the automatic cooking supply amounts are included in the second control table.

[0021] The cooking device of the present invention may include a setting unit capable of setting a second maximum supply amount. Furthermore, even if the second maximum supply amount is set to be less than at least one of the automatic cooking supply amounts, the control unit preferably automatically changes the supply amount to the heating unit based on the automatic cooking supply amount in the automatic cooking mode.

[0022] As a result, in this cooking device, even if the second maximum supply amount is set to be less than each automatic cooking supply amount, each automatic cooking supply amount takes priority in the automatic cooking mode. Therefore, when the automatic cooking mode is executed in the second operating state, the food to be cooked can be heated with a heating power greater than the maximum heating power of the heating unit in the second operating state. As a result, in this cooking device, variations in the quality of automatic cooking due to insufficient heating power of the heating unit are less likely to occur. [Effects of the Invention]

[0023] The cooking device of the present invention can selectively execute a first operating state and a second operating state in which the maximum supply amounts of fuel gas supplied to the heating section are different, and can achieve high-quality automatic cooking.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, first and second embodiments of the present invention will be described with reference to the drawings.

[0026] Example 1 A gas stove 1 according to a first embodiment of the present invention is installed in a kitchen or the like of a house. This gas stove 1 is a so-called built-in gas stove. The gas stove 1 is an example of the "heating cooker" of the present invention.

[0027] In this embodiment, the front-to-back direction and the up-to-down direction of the gas stove 1 are defined by the arrows shown in Fig. 1. In addition, in this embodiment, the right-to-left direction of the gas stove 1 is defined by taking the position of a user (not shown) of the gas stove 1 facing the gas stove 1 from the front as a reference, with the right side of the user being the right side of the gas stove 1 and the left side of the user being the left side of the gas stove 1. These front-to-back, up-to-down, and left-to-right directions are perpendicular to each other.

[0028] 1 and 2, the gas stove 1 includes a main body 10, a top plate 11, first to third burners 12 to 14, a heating grill 15, temperature sensors 16 to 18 for the first to third burners, a grill temperature sensor 19, an operation unit 20, a setting unit 21, a display unit 22, a supply amount adjustment unit 23, a gas supply path 24, and a controller C1. The first burner 12 is an example of the "heating unit" in the present invention.

[0029] The appliance body 10 shown in FIG. 1 is formed in the shape of a generally rectangular box with an open top. As shown in FIG. 2, a gas supply passage 24 is disposed inside the appliance body 10. The gas supply passage 24 includes a main supply passage 24a, a first burner supply passage 24b, a second burner supply passage 24c, a third burner supply passage 24d, and a grill burner supply passage 24e. The main supply passage 24a is connected to a fuel gas supply source provided outside the gas stove 1. The first burner supply passage 24b is connected to the first burner 12. The second burner supply passage 24c is connected to the second burner 13. The third burner supply passage 24d is connected to the third burner 14. The grill burner supply passage 24e is connected to a grill burner 15a, which will be described later.

[0030] As shown in FIG. 1, the top plate 11 is formed in a substantially rectangular plate shape and covers the appliance body 10 from above.

[0031] The first to third burners 12 to 14 are each provided on the top plate 11. More specifically, the first burner 12 is located on the right front side of the top plate 11. The second burner 13 is located on the left front side of the top plate 11. The third burner 14 is located in the rear center of the top plate 11, behind the first and second burners 12 and 13. The top plate 11 is also provided with a first trivet 12a surrounding the first burner 12, and a second trivet 13a surrounding the second burner 13. The top plate 11 is also provided with a third trivet 14a surrounding the third burner 14.

[0032] The first to third stove burners 12 to 14 have the same configuration as known stove burners. That is, the first to third stove burners 12 to 14 burn fuel gas supplied from the gas supply passage 24, respectively, to heat the cooking vessels 25 placed on the first to third trivets 12a to 14a and the food to be cooked (not shown) in the cooking vessels 25 from below. The cooking vessels 25 may be, for example, pots or frying pans. For ease of explanation, the cooking vessels 25 are shown in phantom lines in FIG. 1.

[0033] Here, in this gas stove 1, the first burner 12 and the second burner 13 are formed to be the same size, while the third burner 14 is formed to be smaller than the first and second burners 12, 13. Furthermore, corresponding to the size of the third burner 14, the third trivet 14a is formed to be smaller than the first and second trivets 12a, 13a. Note that the first to third burners 12-14 may all be formed to be the same size, or may be formed to be different sizes. Furthermore, the shapes of the first to third trivets 12a-14a can be designed appropriately according to the shapes of the first to third burners 12-14.

[0034] The first burner temperature sensor 16 is attached to the first burner burner 12. The second burner temperature sensor 17 is attached to the second burner burner 13. The third burner temperature sensor 18 is attached to the third burner burner 14. These first to third burner temperature sensors 16 to 18 detect the temperatures of the foods being heated on the first to third burners 12 to 14. More specifically, the first to third burner temperature sensors 16 to 18 detect the temperature of the bottom of the cooking container 25 that is heated together with the foods on the first to third burners 12 to 14, and detect this temperature as the temperature of the foods being cooked. The first to third burner temperature sensors 16 to 18 are also electrically connected to the controller C1. As a result, the first to third burner temperature sensors 16 to 18 transmit the detected temperatures of the foods to the controller C1.

[0035] The heating grill 15 is provided on the appliance body 10. The heating grill 15 has a grill burner 15a and a heating chamber (not shown). The heating chamber can accommodate food to be cooked together with the cooking container 25. The grill burner 15a burns fuel gas supplied from the gas supply path 24, thereby heating the cooking container 25 in the heating chamber together with the food to be cooked.

[0036] The grill temperature sensor 19 shown in Figure 2 is installed inside the heating chamber. The grill temperature sensor 19 detects the temperature of the food being cooked by the grill burner 15a. More specifically, the grill temperature sensor 19 detects the temperature inside the heating chamber and detects this temperature as the temperature of the food being cooked. The grill temperature sensor 19 is also electrically connected to the controller C1. As a result, the grill temperature sensor 19 transmits the detected temperature of the food to the controller C1.

[0037] The operating unit 20 is capable of igniting and extinguishing the first to third burners 12 to 14 and the grill burner 15a, and is also capable of switching on and off the supply of power to the gas stove 1. The operating unit 20 is electrically connected to the controller C1.

[0038] 1, the operating unit 20 is made up of first to third burner switches 20a to 20c, a grill switch 20d, and a power switch 20e. The first to third burner switches 20a to 20c and the power switch 20e are located on the front right side of the appliance body 10. When pressed by a user, the power switch 20e switches between an ON state in which power is supplied to the gas stove 1 and an OFF state in which power is not supplied to the gas stove 1.

[0039] The first to third burner switches 20a to 20c correspond to the first to third burner burners 12 to 14, respectively. Taking the first burner switch 20a as an example, when the power switch 20e is in the ON state and the first burner burner 12 is turned off, the user presses the first burner switch 20a to ignite the first burner 12. On the other hand, when the power switch 20e is in the ON state and the first burner burner 12 is turned on, the user presses the first burner switch 20a to turn off the first burner 12.

[0040] The grill switch 20d is located on the front left side of the appliance body 10. The grill switch 20d corresponds to the grill burner 15a. When the power switch 20e is in the ON state and the grill burner 15a is extinguished, the user presses the grill switch 20d to ignite the grill burner 15a. On the other hand, when the power switch 20e is in the ON state and the grill burner 15a is ignited, the user presses the grill switch 20d to extinguish the grill burner 15a. Note that the first to third burner switches 20a to 20c, the grill switch 20d, and the power switch 20e may have other configurations.

[0041] The setting unit 21 is electrically connected to the controller C1. The setting unit 21 is composed of a stove setting unit 21a and a grill setting unit 21b. The stove setting unit 21a is an example of the "selection unit" and "setting unit" of the present invention.

[0042] The stove setting section 21a is located on the front right side of the appliance body 10, below the first to third stove switches 20a to 20c. The stove setting section 21a can be operated by a user to select whether the first to third stove burners 12 to 14 will be in the first operating state or the second operating state.

[0043] Here, the first operating state is an operating state in which the maximum supply amount of fuel gas supplied from the gas supply path 24 to the first to third burners 12-14 is a first supply amount. On the other hand, the second operating state is an operating state in which the maximum supply amount of fuel gas supplied from the gas supply path 24 to the first to third burners 12-14 is a second supply amount. This second supply amount is smaller than the first supply amount. In other words, in the second operating state, the maximum supply amount of fuel gas supplied to the first to third burners 12-14 is smaller than in the first operating state. Therefore, the maximum heating power of the first to third burners 12-14 in the second operating state is smaller than the maximum heating power of the first to third burners 12-14 in the first operating state. Note that the burner setting unit 21a may be able to uniformly select the first operating state or the second operating state for the first to third burners 12-14, or may be able to select them individually.

[0044] Furthermore, the stove setting unit 21a allows the user to select an automatic cooking mode by operating it. When the user selects the automatic cooking mode, the gas stove 1 automatically changes the heat power of the first stove burner 12 while automatically cooking the food to be cooked. However, this gas stove 1 cannot automatically change the heat power of the second and third stove burners 13, 14 and the grill burner 15a, and therefore cannot automatically cook the food to be cooked using the second and third stove burners 13, 14 and the heating grill 15.

[0045] Here, the user can select the automatic cooking mode by operating the stove setting section 21a regardless of whether the first to third stove burners 12 to 14 are operating in the first operating state or the second operating state.

[0046] Furthermore, in the stove setting section 21a, when the user selects the automatic cooking mode, the type of cooking menu to be automatically cooked by the first stove burner 12 can be selected.

[0047] Furthermore, in the stove setting section 21a, when the user has not selected the automatic cooking mode, the user can select the heat power position to be executed by the first to third stove burners 12 to 14, that is, the heat power of the first to third stove burners 12 to 14. The heat power positions will be described in detail later.

[0048] Furthermore, in the stove setting section 21a, the user can set the maximum supply amount of fuel gas in the second operating state, that is, the value of the second supply amount.

[0049] The grill setting section 21b is located on the front left side of the appliance body 10, below the grill switch 20d. The stove setting section 21a allows the user to select between high heat and low heat, which is weaker than high heat, for the heat output of the grill burner 15a. The stove setting section 21a also allows the user to set the time for heating the food on the grill burner 15a, and therefore the heating grill 15.

[0050] 2, the display unit 22 is electrically connected to the controller C1. The display unit 22 is made up of a stove display unit 22a and a grill display unit 22b.

[0051] As shown in FIG. 1, the stove display unit 22a and the grill display unit 22b each comprise a liquid crystal display. The stove display unit 22a is located on the front right side of the appliance body 10, below the first to third stove switches 20a to 20c. The stove display unit 22a displays the first operating state, the second operating state, the automatic cooking mode, and the operating states of the first to third stove burners 12 to 14, such as the current heat positions of the first to third stove burners 12 to 14. In the automatic cooking mode, the stove display unit 22a also displays a message that automatic cooking of the food has been completed. Furthermore, when the user sets the second supply amount, the stove display unit 22a displays the value to be set as the second supply amount.

[0052] The grill display unit 22b is located below the grill switch 20d on the front left side of the appliance body 10. The grill switch 20d displays information on high or low heat, as well as the operating status of the heating grill 15, such as the time it will take to heat the food on the heating grill 15.

[0053] 2, the supply amount adjuster 23 is provided in the gas supply path 24. Although not shown in detail, the supply amount adjuster 23 is configured with a plurality of flow rate adjustment valves, a stepping motor, etc. The supply amount adjuster 23 is also electrically connected to the controller C1.

[0054] The supply amount adjustment unit 23 is capable of adjusting the amount of fuel gas supplied to the first to third burners 12 to 14 and the grill burner 15a in stages. In the gas stove 1, the supply amount adjustment unit 23 is capable of adjusting the amount of fuel gas supplied to the first to third burners 12 to 14 in 11 stages, from minimum to maximum (see FIGS. 3 and 4). Meanwhile, the supply amount adjustment unit 23 is capable of adjusting the amount of fuel gas supplied to the grill burner 15a in two stages. The supply amount adjustment unit 23 may adjust the amount of fuel gas supplied to the first to third burners 12 to 14 in stages other than 11 stages. The supply amount adjustment unit 23 may also adjust the amount of fuel gas supplied to the grill burner 15a in three or more stages.

[0055] The controller C1 is disposed inside the appliance body 10. The controller C1 includes a memory unit C11 and a control unit C12. The memory unit C11 stores a control program 7 for controlling the operation of the gas stove 1, including the first to third burners 12 to 14 and the supply amount adjustment unit 23. The memory unit C11 also stores an automatic cooking program 8 for causing the first burner 12 to automatically cook food in an automatic cooking mode.

[0056] Furthermore, the storage unit C11 stores a first control table 31 shown in FIG. 3 and a second control table 32 shown in FIG.

[0057] 3, the amount of fuel gas supplied to the first stove burner 12 in the first operating state is allocated to 11 levels, and 11 manual selection power positions and 4 automatic cooking power positions are set. The manual selection power positions are power positions of the first stove burner 12 that the user can select through the stove setting unit 21a when the automatic cooking mode is not selected in the first operating state. On the other hand, the automatic cooking power positions are power positions of the first stove burner 12 used in the automatic cooking mode.

[0058] 4, the second control table 32 allocates the amount of fuel gas supplied to the first stove burner 12 in the second operating state to 11 levels, and also provides 11 manual selection heat positions and 4 automatic cooking heat positions. The manual selection heat positions in the second control table 32 are the heat positions of the first stove burner 12 that the user can select through the stove setting unit 21a when the automatic cooking mode is not selected in the second operating state.

[0059] Thus, in this gas stove 1, when the user has not selected the automatic cooking mode, the user can select 11 heat power positions, i.e., manual selection heat power positions, through the stove setting unit 21a, regardless of whether the first stove burner 12 is in the first or second operating state. On the other hand, in this gas stove 1, when the user has selected the automatic cooking mode, the food to be cooked is automatically cooked using the first stove burner 12, using the four automatic cooking heat power positions.

[0060] 3, in the first control table 31, the fuel gas supply amount in the first operating state is allocated to 11 levels ranging from the minimum of "300" to the maximum of "3600." In other words, the fuel gas supply amount of "3600" in the first operating state corresponds to the "first maximum supply amount" in the present invention. These 11 levels of fuel gas supply amount correspond to the 11 levels of manually selectable heating power positions, respectively.

[0061] Taking the supply of fuel gas to the first burner 12 as an example, a fuel gas supply amount of "300" is a supply amount that will result in the heating power of the first burner 12 being 300 kcal per hour. Similarly, a fuel gas supply amount of "3600" is a supply amount that will result in the heating power of the first burner 12 being 3600 kcal per hour. Note that each value of the fuel gas supply amount in the first operating state can be set appropriately.

[0062] As a result, in the first control table 31, when the manual selection heat power position is "11," the fuel gas supply amount is "3600," i.e., the first maximum supply amount. Therefore, when the manual selection heat power position is "11," the heat power of the first burner 12 becomes the maximum heat power. Also, in the first control table 31, when the manual selection heat power position is "10," the fuel gas supply amount becomes "3270," which is less than the first maximum supply amount. As a result, when the selection heat power position is "10," the heat power of the first burner 12 becomes less than the maximum heat power. Furthermore, in the first control table 31, as the selection heat power position decreases in stages from "10" to "9," "8," etc., the fuel gas supply amount also decreases in stages, and therefore the heat power of the first burner 12 also decreases in stages. In the first control table 31, when the manual selection heat power position is "1," the fuel gas supply amount is the minimum, "300." Therefore, when the selection heat power position is "1," the heat power of the first stove burner 12 becomes the minimum heat power.

[0063] In the first control table 31, the fuel gas supply amount of "2000" corresponds to the manual selection heat power position "6" and also corresponds to the automatic cooking heat power position "4." Similarly, the fuel gas supply amount of "1290" corresponds to the manual selection heat power position "4" and also corresponds to the automatic cooking heat power position "3." Furthermore, the fuel gas supply amount of "630" corresponds to the manual selection heat power position "2" and also corresponds to the automatic cooking heat power position "2." And the fuel gas supply amount of "300" corresponds to the manual selection heat power position "1" and also corresponds to the automatic cooking heat power position "1."

[0064] In other words, these fuel gas supply amounts "2000," "1290," "630," and "300" serve as the fuel gas supply amounts for the manually selectable heat power positions "6," "4," "2," and "1" in the first operating state, as well as the automatic cooking supply amount, which is the fuel gas supply amount in the automatic cooking mode. Thus, the first control table 31 includes the first maximum supply amount in the first operating state as well as the automatic cooking supply amount in the automatic cooking mode. The value of the automatic cooking supply amount can be set as appropriate.

[0065] As shown in Fig. 4, in the second control table 32, the fuel gas supply amount in the second operating state is allocated to 11 levels ranging from a minimum of "300" to a maximum of "2500." In other words, the fuel gas supply amount of "2500" in the second operating state corresponds to the "second maximum supply amount" in the present invention. In this second control table 32, these 11 levels of fuel gas supply amount also correspond to the 11 levels of manually selectable heating power positions. The value of the fuel gas supply amount in the second operating state can also be set appropriately.

[0066] In the second control table 32, when the manual selection heat power position is "11," the fuel gas supply amount is "2500," i.e., the second maximum supply amount. Therefore, as in the first operating state, in the second operating state, the heat power of the first burner 12 is the maximum when the manual selection heat power position is "11." Here, the second maximum supply amount is smaller than the first maximum supply amount in the first operating state described above. Therefore, in this gas stove 1, the maximum heat power of the first burner 12 in the second operating state is smaller than the maximum heat power of the first burner 12 in the first operating state.

[0067] Also, in the second control table 32, as the manual selection heat power position gradually decreases from "10," "9," "8," etc., the fuel gas supply amount also gradually decreases. Therefore, as the selection heat power position gradually decreases from "10," "9," "8," etc., the heat power of the first stove burner 12 also gradually decreases. And in the second control table 32, when the manual selection heat power position is "1," the fuel gas supply amount is the minimum of "300." Therefore, when the selection heat power position is "1," the heat power of the first stove burner 12 becomes the minimum heat power.

[0068] In the second control table 32, the fuel gas supply amount of "2000" corresponds to the manual selection heat power position "9" and the automatic cooking heat power position "4." Similarly, the fuel gas supply amount of "1290" corresponds to the manual selection heat power position "5" and the automatic cooking heat power position "3." Furthermore, the fuel gas supply amount of "630" corresponds to the manual selection heat power position "2" and the automatic cooking heat power position "2." Furthermore, the fuel gas supply amount of "300" corresponds to the manual selection heat power position "1" and the automatic cooking heat power position "1." Thus, the second control table 32 includes the automatic cooking supply amount in the automatic cooking mode in addition to the second maximum supply amount in the second operating state.

[0069] As described above, the fuel gas supply amounts of "2000," "1290," "630," and "300" are also included in the first control table 31. In other words, the fuel gas supply amounts of "2000," "1290," "630," and "300," which correspond to the four automatic cooking supply amounts, are included in both the first control table 31 and the second control table 32. In other words, the 11 levels of fuel gas supply amounts in the first operating state (see FIG. 3) and the 11 levels of fuel gas supply amounts in the second operating state (see FIG. 4) both include four levels of automatic cooking supply amounts.

[0070] As a result, in this gas stove 1, the heating power of the first burner 12 is equal at manual selection power position "6" in the first operating state, manual selection power position "9" in the second operating state, and automatic cooking power position "4." Similarly, the heating power of the first burner 12 is equal at manual selection power position "4" in the first operating state, manual selection power position "5" in the second operating state, and automatic cooking power position "3." Furthermore, the heating power of the first burner 12 is equal at manual selection power position "2" in the first operating state, manual selection power position "2" in the second operating state, and automatic cooking power position "2."

[0071] The heating power of the first burner 12 is the same in the manual selection heating power position "1" in the first operating state, the manual selection heating power position "1" in the second operating state, and the automatic cooking heating power position "1." In other words, in this gas stove 1, the minimum heating power of the first burner 12 is the same whether the automatic cooking mode is selected or not selected in the first operating state and the second operating state.

[0072] Furthermore, in this gas stove 1, there are four automatic cooking power positions used in the automatic cooking mode, and the fuel gas supply amount in automatic cooking power position "4" is the maximum fuel gas supply amount to the first burner 12 in the automatic cooking mode. Specifically, the fuel gas supply amount in automatic cooking power position "4" is "2000." In contrast, the fuel gas supply amount corresponding to manual selection power position "11" in the first operating state is "3600," and the fuel gas supply amount corresponding to manual selection power position "11" in the second operating state is "2500." Therefore, in this gas stove 1, the maximum heating power of the first burner 12-14 in the automatic cooking mode is smaller than the maximum heating power of the first burner 12 when the automatic cooking mode is not selected in the first and second operating states.

[0073] In this gas stove 1, the first control table 31 shown in Fig. 3 must include four levels of fuel gas supply amount for automatic cooking among the 11 levels of fuel gas supply amount in the first operating state. In other words, when allocating the fuel gas supply amount in the first operating state into 11 levels from the minimum of "300" to the maximum of "3600," the fuel gas supply amounts of "2000," "1290," "630," and "300" must be included. As a result, although the first control table 31 allocates the fuel gas supply amount in the first operating state as evenly as possible among the 11 levels, it is impossible to allocate it completely evenly among the 11 levels.

[0074] Similarly, in the second control table 32 shown in Fig. 4, the 11 levels of fuel gas supply amount in the second operating state must include 4 levels of supply amount for automatic cooking. For this reason, when allocating the fuel gas supply amount in the second operating state to 11 levels from the minimum of "300" to the maximum of "2500", the amount is allocated as evenly as possible among the 11 levels, but it is impossible to allocate it completely evenly among the 11 levels.

[0075] Here, in the second operating state, the difference between the minimum and maximum fuel gas supply rates is smaller than in the first operating state. Therefore, in the second control table 32, by including four automatic cooking supply rate levels in the 11 fuel gas supply rate levels in the second operating state, the variation in the supply rate between each level is greater than the variation in the supply rate between each level in the first control table 31. As a result, as shown in Figure 5, in this gas stove 1, the variation in the fuel gas supply rate resulting from a one-level change in the manual selection heat position in the second operating state is inevitably greater than the variation in the fuel gas supply rate resulting from a one-level change in the manual selection heat position in the first operating state.

[0076] Although not shown, the memory unit C11 stores a third control table corresponding to the control of the supply amount adjuster 23 for the second burner 13 in the first operating state and a fourth control table corresponding to the control of the supply amount adjuster 23 for the second burner 13 in the second operating state. Furthermore, the memory unit C11 stores a fifth control table corresponding to the control of the supply amount adjuster 23 for the third burner 14 in the first operating state and a sixth control table corresponding to the control of the supply amount adjuster 23 for the third burner 14 in the second operating state. The memory unit C11 also stores a grill control table corresponding to the control of the supply amount adjuster 23 for the grill burner 15a. The contents of the third and fifth control tables may be the same as or different from the first control table 31. Similarly, the contents of the fourth and sixth control tables may be the same as or different from the second control table 32. In addition, the third and fourth control tables may be omitted, and the first control table 31 and the second control table 32 may be used to control the supply amount adjustment unit 23 for the second stove burner 13, as in the first stove burner 12.

[0077] 2, there are multiple automatic cooking programs 8 corresponding to the types of cooking menus that can be automatically cooked by the first stove burner 12. The automatic cooking program 8 records the type of automatic cooking heat position to be used and the conditions for changing the automatic cooking heat position according to the type of cooking menu. Note that conditions for changing the automatic cooking heat position include, for example, the temperature of the food to be cooked and the heating time for the food to be cooked.

[0078] In the gas stove 1 configured as described above, it is possible to heat and cook food on the first to third burners 12 to 14 and the heating grill 15. In addition, in this gas stove 1, the user can select the first or second operating state. In either the first or second operating state, in this gas stove 1, the user can select the automatic cooking mode, which allows the food to be cooked automatically on the first burner 12.

[0079] Below, we will explain the cases where the user has not selected the automatic cooking mode and where the user has selected the automatic cooking mode, using the first stove burner 12 as an example.

[0080] When cooking food using the first stove burner 12, if the power switch 20e is in the OFF state, the user presses the power switch 20e to switch it to the ON state (step S101 in FIG. 6). This causes the control unit C12 of the controller C1 to read the current operating state setting based on the user's selection of the first operating state or the second operating state (step S102).

[0081] If the current operating state setting is the first operating state (step S103: YES), the control unit C12 selects and reads the first control table 31 stored in the memory unit C11 (step S110).Then, the control unit C12 determines whether the user has selected the automatic cooking mode (step S104).

[0082] On the other hand, if the current operating state setting is the second operating state (step S103: NO), the control unit C12 selects and reads the second control table 32 stored in the memory unit C11 (step S120).Then, the control unit C12 determines whether the user has selected the automatic cooking mode (step S104).

[0083] If the user has not selected the automatic cooking mode (step S104: YES), the control unit C12 does not execute the automatic cooking mode, and waits until the user turns on the first burner 12 through the first burner switch 20a (step S105: NO).

[0084] Then, when the user performs an operation to ignite the first burner 12 (step S105: YES), the control unit C12 controls the supply amount adjustment unit 23. As a result, the supply amount adjustment unit 23 starts supplying fuel gas from the gas supply path 24 to the first burner 12. In this way, the first burner 12 is ignited and heating of the food to be cooked begins, and cooking of the food on the first burner 12 begins.

[0085] In this gas stove 1, if the user has not selected the automatic cooking mode (step S104: YES), the user can change the amount of fuel gas supplied to the first burner 12, i.e., the heat power of the first burner 12, in 11 stages, regardless of whether the first or second operating state is selected. In this way, the user can cook the food on the first burner 12 while arbitrarily changing the manually selected heat power position between "1" and "11" according to the progress of cooking the food on the first burner 12 (step S106). During this time, the control unit C12 controls the supply amount adjustment unit 23 based on the first control table 31 so that the amount of fuel gas supplied corresponds to the manually selected heat power position selected by the user.

[0086] Cooking of the food on the first burner 12 continues until the user turns off the first burner 12 using the first burner switch 20a (step S107: NO). When the user turns off the first burner 12 (step S107: YES), the control unit C12 controls the supply amount adjustment unit 23 to stop the supply of fuel gas to the first burner 12.

[0087] This completes cooking of the food on the first burner 12. Furthermore, when cooking of the food on the first burner 12 is completed, the user switches the power switch 20e to the OFF state. Note that with this gas stove 1, if the power switch 20e is in the ON state and a certain period of time has passed without any ignition operation being performed on any of the first to third burners 12 to 14 or the heating grill 15, the power switch 20e will automatically switch to the OFF state.

[0088] On the other hand, if the control unit C12 determines in step S104 that the user has selected the automatic cooking mode (step S104: NO), it loads the automatic cooking program 8 corresponding to the type of cooking menu selected by the user from the automatic cooking programs 8 stored in the memory unit C11. Even if the user has selected the automatic cooking mode, this gas stove 1 requires the user to personally ignite the first to third burners 12 to 14. Therefore, the control unit C12 waits until the user ignites the first burner 12 using the first burner switch 20a (step S201: NO shown in FIG. 7).

[0089] When the user turns on the first burner 12 (step S201: YES), the control unit C12 starts automatic cooking of the food based on the automatic cooking program 8. For the cooking menu currently selected by the user, the control unit C12 first sets the automatic cooking heat position to "3" (step S202). This causes the food to begin heating using the heat of the first burner 12 according to the amount of fuel gas supplied at automatic cooking heat position "3." The control unit C12 also obtains the temperature of the food being heated from the temperature transmitted from the first burner temperature sensor 16.

[0090] Then, control unit C12 continues heating the food while maintaining the automatic cooking heat position at "3" until the temperature of the food reaches 100°C (step S203: NO). Then, when the temperature of the food reaches 100°C (step S203: YES), control unit C12 sets the automatic cooking heat position to "1" (step S204). This allows the food to continue to be heated using the heat of the first burner 12 according to the amount of fuel gas supplied at automatic cooking heat position "1," i.e., the minimum heat of the first burner 12. Furthermore, control unit C12 starts measuring the heating time at the same time as setting the automatic cooking heat position to "1."

[0091] The first stove burner 12 continues to heat the food at its minimum power until the heating time reaches one minute (step S205: NO). After the one minute heating time has elapsed (step S205: YES), the control unit C12 alternately changes the automatic cooking heat position between "3" and "1" to maintain the food temperature at 140°C (step S206). The process of step S206 continues until three minutes and 30 seconds have elapsed (step S207: NO).

[0092] Then, when 3 minutes and 30 seconds have passed, the control unit C12 sets the automatic cooking heat position to "1" (step S208). If the automatic cooking heat position is "1" when 3 minutes and 30 seconds have passed, the automatic cooking heat position is maintained at "1" in step S208.

[0093] Thus, heating of the food to be cooked at this minimum heat power continues for 13 minutes (step S209). Then, when 13 minutes have passed since the processing of step S208, control unit C12 determines that cooking of the food to be cooked is complete. As a result, control unit C12 automatically extinguishes first burner 12 without relying on user operation (step S210). This ends automatic cooking of the food to be cooked on first burner 12.

[0094] In this way, the operating states of the first to third burners 12 to 14 can be changed between the first operating state and the second operating state in this gas stove 1. Furthermore, in this gas stove 1, if the user has not selected the automatic cooking mode, the user can change the amount of fuel gas supplied to the first to third burners 12 to 14 in 11 stages in either the first operating state or the second operating state.

[0095] Here, taking the first burner 12 as an example, the second maximum supply amount in the second operating state is smaller than the first maximum supply amount in the first operating state, so the maximum heating power of the first burner 12 is smaller in the second operating state than in the first operating state. Although the first and second operating states share some fuel gas supply amounts, the second operating state provides a smaller overall amount of fuel gas to the first burner 12 at each stage than in the first operating state. Therefore, in this gas stove 1, when cooking food using the first burner 12 does not require a significant amount of heating power, the second operating state can be used to reduce fuel gas consumption, even if the manually selectable heating power position is set to "11."

[0096] On the other hand, when cooking food using the first burner 12 and a large amount of heat is required, the user can select the first operating mode and set the manual heat position to "11," allowing the food to be heated appropriately on this gas stove 1. The same applies to the second and third burners 13 and 14.

[0097] In addition, in this gas stove 1, when a user selects the automatic cooking mode, the control unit C12 executes the automatic cooking mode regardless of whether the first burner 12 is currently operating in the first or second operating state. In this gas stove 1, four automatic cooking power positions are set in both the first control table 31 and the second control table 32. Therefore, in the automatic cooking mode, the control unit C12 automatically changes the fuel gas supply rate of the first burner 12 according to four automatic cooking supply rates corresponding to the four automatic cooking power positions. In this gas stove 1, the automatic cooking supply rates are "2000," "1290," "630," and "300," and these four automatic cooking supply rates are common to both the first and second operating states. Furthermore, each of these automatic cooking supply rates is less than the first maximum supply rate of "3600" in the first operating state. Furthermore, each of these supply amounts for automatic cooking is less than the second maximum supply amount of "2500" in the second operating state.

[0098] As a result, in this gas stove 1, the maximum heating power of the first burner 12 in the automatic cooking mode is smaller than the maximum heating power of the first burner 12 in the first and second operating states. Therefore, in the automatic cooking mode, the food to be cooked is heated with a heating power that is smaller than the maximum heating power of the first burner 12 in the first and second operating states.

[0099] Thus, in this gas stove 1, whether the control unit C12 executes the automatic cooking mode in the first operating state or the second operating state, variations in the results of automatic cooking due to insufficient heating power of the first stove burner 12 are unlikely to occur.

[0100] Therefore, the gas stove 1 of Example 1 can selectively execute a first operating state and a second operating state in which the maximum supply amounts of fuel gas supplied to the first to third stove burners 12 to 14 are different, while still achieving high-quality automatic cooking.

[0101] In particular, in this gas stove 1, four automatic cooking heat positions and four automatic cooking supply amounts are included in both the first control table 31 and the second control table 32. Therefore, in this gas stove 1, a dedicated control table for the fuel gas supply amount to be used in the automatic cooking mode is not required.

[0102] Furthermore, with this gas stove 1, the user can set a second maximum supply amount, i.e., the maximum supply amount of fuel gas in the second operating state, through the stove setting unit 21a. This allows the second maximum supply amount to be set smaller than "2500" or, conversely, larger than "2500" as long as it does not exceed the first maximum supply amount. Here, if the user changes the second maximum supply amount, the control unit C12 allocates and sets the fuel gas supply amount in the second operating state into 11 stages, with the changed second maximum supply amount as the upper limit.

[0103] In this way, with this gas stove 1, the maximum heating power of the first to third burners 12 to 14 in the second operating state can be appropriately set according to the type of food being cooked with the first to third burners 12 to 14 and the user's intentions. This also makes this gas stove 1 highly convenient.

[0104] Here, in this gas stove 1, the second maximum supply amount of fuel gas to the first burner 12 can be set to be less than "2000", which is the maximum value of the supply amount for automatic cooking. Even in this case, the four levels of the supply amount for automatic cooking are not affected, and in the automatic cooking mode, the supply amount of fuel gas to the first burner 12 automatically changes between four levels: "2000", "1290", "630", and "300".

[0105] Therefore, in this gas stove 1, even if the maximum heating power of the first burner 12 in the second operating state is lower than the maximum heating power of the first burner 12 in the automatic operation mode, there is no need to reset the automatic cooking supply amount. As a result, the processing load on the control unit C12 is also reduced in this gas stove 1. Similarly, the second and third burners 13 and 14 can also have their second maximum supply amounts set lower than the maximum value of the automatic cooking supply amount for the first burner 12.

[0106] Example 2 8, in the gas stove 2 of the second embodiment, the memory unit C11 stores a second control table 33 instead of the second control table 32. In addition, in this gas stove 2, the memory unit C11 stores an automatic cooking control table 34.

[0107] As shown in Figure 9, in the second control table 33, similar to the second control table 32 of Example 1, the fuel gas supply amount in the second operating state is allocated to 11 stages ranging from the minimum of "300" to the maximum of "2500" in accordance with the manually selected heating power position.

[0108] Unlike the second control table 32 of the first embodiment, the second control table 33 does not include a heating power position for automatic cooking. Therefore, the second control table 33 does not include a supply amount for automatic cooking.

[0109] As shown in FIG. 10, the automatic cooking control table 34 sets the fuel gas supply amount in the automatic cooking mode and the automatic cooking heat position. As in the first embodiment, the automatic cooking control table 34 also sets the fuel gas supply amount in the automatic cooking mode to four levels: "2000," "1290," "630," and "300." The fuel gas supply amount of "2000" corresponds to the automatic cooking heat position "4." The fuel gas supply amount of "1290" corresponds to the automatic cooking heat position "3." The fuel gas supply amount of "630" corresponds to the manual selection heat position "2." The fuel gas supply amount of "300" corresponds to the manual selection heat position "1." Other components of the gas stove 2 are similar to those of the gas stove 1 of the first embodiment, and the same components are designated by the same reference numerals, and detailed descriptions of the components will be omitted.

[0110] In this gas stove 2, the control unit C12 controls the supply amount adjuster 23 for the first burner 12 based on the first control table 31 in the first operating state, as in Example 1. Meanwhile, in the second operating state, the control unit C12 controls the supply amount adjuster 23 for the first burner 12 based on the second control table 33. Then, in this gas stove 2, when the user selects the automatic cooking mode, the control unit C12 appropriately selects one of four automatic cooking heat positions based on the automatic cooking control table 34, and controls the supply amount adjuster 23 so that fuel gas is supplied to the first burner 12 at an automatic cooking supply amount corresponding to each automatic cooking heat position. Note that the control of the supply amount adjuster 23 for the second and third burners 13 and 14 in this gas stove 2 is performed in the same manner as in the gas stove 1 of Example 1.

[0111] Therefore, similar to the gas stove 1 of Example 1, in this gas stove 1, whether the control unit C12 executes the automatic cooking mode in the first operating state or the second operating state, variations in the results of automatic cooking due to insufficient heating power of the first stove burner 12 are unlikely to occur.

[0112] Furthermore, in this gas stove 2, the second control table 33 does not have a heat position for automatic cooking set, and does not include an amount of supply for automatic cooking. As a result, in this second control table 33, when allocating and setting the fuel gas supply amount in the second operating state into 11 levels, it is not necessary to include four levels of supply for automatic cooking.

[0113] That is, as described above, in the gas stove 1 of Example 1, it is necessary to include four levels of automatic cooking supply amounts in each of the first control table 31 and the second control table 32. Therefore, in the gas stove 1 of Example 1, it is impossible to evenly allocate the fuel gas supply amount among 11 levels in either the first or second operating state. In particular, since the second maximum supply amount in the second operating state is smaller than the first maximum supply amount in the first operating state, the difference between the maximum and minimum values ​​of the fuel gas supply amount is smaller in the second operating state than in the first operating state. As a result, the second control table 32 exhibits more significant variations in the fuel gas supply amount between each level than the first control table 31 (see FIG. 5). As a result, in the gas stove 1 of Example 1, when it is in the second operating state, compared to when it is in the first operating state, even if the user lowers the manual selection heat position by one level, the amount of fuel gas supplied does not change much, and the heat of the first burner 12 does not change much. Also, in the gas stove 1 of Example 1, when the user raises the manual selection heat position by one level, the amount of fuel gas supplied changes significantly, and the heat of the first burner 12 changes significantly.

[0114] In contrast, in the gas stove 2 of Example 2, there is no need to include four levels of automatic cooking supply amounts in the second control table 33. As a result, the second control table 33 provides greater flexibility in allocating the fuel gas supply amount in the second operating state compared to when four levels of automatic cooking supply amounts are included. As a result, even with the second control table 33, it is difficult to allocate the fuel gas supply amount in the second operating state completely evenly among 11 levels, but the variation in the supply amount between each level is minimized compared to the second control table 32 of Example 1.

[0115] 11, in this gas stove 2, compared to the gas stove 1 of Example 1, when the user lowers the manual selection heat position by one level in the second operating state, the amount of fuel gas supplied is suitably reduced. Also, in this gas stove 2, when the user raises the manual selection heat position by one level in the second operating state, the amount of fuel gas supplied is suitably increased. Thus, in this gas stove 2, the heat of the first burner 12 can be suitably changed in response to the user's change of the manual selection heat position. Other functions of this gas stove 2 are the same as those of the gas stove 1 of Example 1.

[0116] The present invention has been described above in accordance with Examples 1 and 2, but it goes without saying that the present invention is not limited to the above Examples 1 and 2, and can be modified and applied as appropriate within the scope of the invention.

[0117] For example, in the gas stoves 1 and 2 of Examples 1 and 2, the user can select between the first operating state and the second operating state. However, this is not limited to this. When the gas stove 1 is manufactured, the second operating state may be initially set, and if the user wishes to change to the first operating state, a specialized technician such as a maintenance worker may operate the stove setting unit 21a to change from the second operating state to the first operating state. The same applies when the first operating state is initially set when the gas stove 1 is manufactured, and the user wishes to change to the second operating state.

[0118] Furthermore, the gas stoves 1 and 2 of the first and second embodiments may be configured to require the user or maintenance worker to input a dedicated password or the like when switching the operating state between the first operating state and the second operating state.

[0119] Furthermore, in the gas stove 1 of Examples 1 and 2, the first burner 12 is the "heating section" of the present invention. However, this is not limited to this, and the second burner 13 or the third burner 14 may be the "heating section" of the present invention, or all of the first to third burners 12 to 14 may be the "heating section" of the present invention. Furthermore, instead of the first to third burners 12 to 14, the grill burner 15a may be the "heating section" of the present invention. Furthermore, the first to third burners 12 to 14 and the grill burner 15a may be the "heating section" of the present invention.

[0120] In the gas stoves 1 and 2 of Examples 1 and 2, the second and third burners 13 and 14 and the grill burner 15a may also be able to execute the automatic cooking mode based on the user's selection. In this case, the first burner 12, the second burner 13, the third burner 14 and the grill burner 15a may each have different types of cooking menus that can be automatically cooked.

[0121] Furthermore, in the gas stove 2 of Example 2, when the automatic cooking mode is executed in the first operating state, the control unit C12 may control the supply amount adjustment unit 23 based on the first control table 31. The first control table 31 includes four levels of supply amounts for automatic cooking and heat positions for automatic cooking, so even in this case, the first stove burner 12 can suitably perform automatic cooking of the food to be cooked. [Industrial Applicability]

[0122] The present invention can be used in home cooking appliances, kitchen equipment, and the like. [Explanation of symbols]
