The motor valve 7 uses the motor 92 as a drive source, and adjusts the opening degree of the valve by driving the motor 92. As shown in FIGS. 5A and 5B, the motor valve 7 includes a first member 71 connected to a gas supply source, a second member 86 connected to the grill burner 6, and a motor 92.

  The first member 71 is provided with a gas hole 74 having an opening area corresponding to the heating amount of the upper burner portion 61 and a gas hole 74 having an opening area corresponding to the heating amount of the lower burner portion 62. Hereinafter, the heating amount obtained by combining the heating amount of the upper burner portion 61 and the heating amount of the lower burner portion 62 is referred to as “combined heating amount” as necessary.

  Specifically, the first member 71 includes an upper burner member 72 for determining the gas supply amount of the upper burner portion 61 and a lower burner member 81 for determining the gas supply amount of the lower burner portion 62. ing. The upper burner member 72 and the lower burner member 81 may be separate members or integrally formed members.

The upper burner member 72 of this embodiment includes a large hole 75 for high fire and a small hole 76 for low fire as the plurality of gas holes 74. The large hole 75 has a larger opening area than the small hole 76 (that is, has a larger diameter than the small hole 76). The upper burner member 72 includes a closing portion 73, a large hole 75 (first gas hole 77), a large hole 75 (second gas hole 78), a small hole 76 (third gas hole 79), and a small hole. 76 (fourth gas hole 80) are arranged in this order.

  The lower burner member 81 is also provided with a closing portion 73 and a plurality of gas holes 74. The closing portion 73 is a portion where the gas hole 74 is not provided, and closes the second hole 89 when it overlaps the second hole 89 of the second member 86. The plurality of gas holes 74 are arranged in one direction, and are arranged so that the center of each gas hole 74 is positioned on a straight line.

  The lower burner member 81 of the present embodiment is provided with a large hole 75 for high fire and a small hole 76 for low fire as the upper burner member 72 as a plurality of gas holes 74. The lower burner member 81 includes a closing portion 73, a large hole 75 (first gas hole 82), a small hole 76 (second gas hole 83), a large hole 75 (third gas hole 84), and a small hole. 76 (fourth gas hole 85) are arranged in this order.

  The first gas holes 82 of the lower burner member 81 are arranged in the vertical direction with respect to the first gas holes 77 of the upper burner member 72, and the center thereof is disposed at the same position when viewed in the left-right direction. The Similarly, the second gas holes 78 and 83, the third gas holes 79 and 84, and the fourth gas holes 80 and 85 are arranged in the same manner.

  In this manner, the first member 71 of the present embodiment has the gas holes 74 corresponding to the combined heating amount in which the heating amount of the upper burner portion 61 and the heating amount of the lower burner portion 62 are combined. A plurality of sets (four sets in this embodiment) are provided. That is, the first combined heating amount is generated by the first gas hole 77 (high fire) of the upper burner member 72 and the first gas hole 82 (high fire) of the lower burner member 81. A second combined heating amount is generated by the second gas hole 78 (high fire) of the upper burner member 72 and the second gas hole 83 (low fire) of the lower burner member 81. A third combined heating amount is generated by the third gas hole 79 (low heat) of the upper burner member 72 and the third gas hole 84 (high fire) of the lower burner member 81. A fourth combined heating amount is generated by the fourth gas hole 80 (low heat) of the upper burner member 72 and the fourth gas hole 85 (low heat) of the lower burner member 81.

  The second member 86 is disposed adjacent to the first member 71. The second member 86 moves in a direction parallel to the juxtaposed direction of the gas holes 74 of the upper burner member 72 of the first member 71 and the juxtaposed direction of the gas holes 74 of the lower burner member 81. As shown in FIG. 5B, the second member 86 includes a control plate 87 and a connecting portion 90 that connects the control plate 87 and the motor 92.

  The control plate 87 extends in the driving direction and is formed in a substantially rectangular shape. At the approximate center in the length direction of the control plate 87, two holes arranged in the vertical direction (the upper hole is referred to as the first hole 88 and the lower hole is referred to as the second hole 89) are provided.

  A gas to be supplied to the upper burner unit 61 flows through the first hole 88. That is, the first hole 88 communicates with the upper burner portion 61. When the control plate 87 is driven, the first hole 88 selectively communicates with any one of the plurality of gas holes 74 of the upper burner member 72. Thereby, the fuel gas supplied from the gas hole 74 of the upper burner member 72 of the first member 71 flows into the second member 86 through the first hole 88 and is supplied to the upper burner portion 61.

  A gas to be supplied to the lower burner portion 62 flows through the second hole 89. The second hole 89 of the present embodiment communicates with the lower burner part 62. The second hole 89 selectively communicates with any one of the plurality of gas holes 74 of the lower burner member 81 when the control plate 87 is driven. Accordingly, the fuel gas supplied from the gas hole 74 of the lower burner member 81 of the first member 71 flows into the second member 86 through the second hole 89 and is supplied to the lower burner portion 62.

  The diameters of the first hole 88 and the second hole 89 are formed to be approximately the same as the diameter of the large hole 75, but when located between the gas holes 74, the adjacent gas holes 74 are formed. (That is, the first hole 88 and the second hole 89 of the second member 86 are not closed when located at a place other than the closing portion 73).

  The connecting portion 90 is fixed to the control plate 87 and has a function of converting the rotational driving of the motor 92 into linear driving. The connection part 90 is formed in a cylindrical shape, for example, and an internal thread part 91 is formed on the inner peripheral surface.

  The motor 92 is an electric motor that is driven to rotate by receiving electric power. The motor 92 of this embodiment is configured by a stepping motor 92. The output shaft 93 of the motor 92 is provided with a male screw portion 94 that is screwed into the female screw of the connecting portion 90. When the output shaft 93 rotates, the connecting portion 90 linearly moves in a direction parallel to the output shaft 93. The motor 92 is electrically connected to the control unit 13, and driving is controlled by the control unit 13.

  By driving the motor 92 and changing the position of the second member 86, the first hole 88 and the second hole 89 are formed in the gas hole 74 of the first member 71 as shown in FIGS. By selectively communicating, the flow rate of the fuel gas supplied to the grill burner 6 is controlled.

  When the first combined heating amount is generated by the grill burner 6, the control unit 13 drives the motor 92 to move the control plate 87 to the position shown in FIG. 6A. Then, the first hole 88 overlaps the first gas hole 77 of the upper burner member 72, and the second hole 89 overlaps the first gas hole 82 of the lower burner member 81. As a result, the upper burner portion 61 becomes a strong fire and the lower burner portion 62 becomes a strong fire.

  When the second combined heating amount is generated by the grill burner 6, the control unit 13 drives the motor 92 and moves the control plate 87 to the position shown in FIG. 6B. Then, the first hole 88 overlaps with the second gas hole 78 of the upper burner member 72, and the second hole 89 overlaps with the second gas hole 83 of the lower burner member 81. As a result, the upper burner portion 61 becomes a high fire and the lower burner portion 62 becomes a low fire.

  When the third combined heating amount is generated by the grill burner 6, the control unit 13 drives the motor 92 to move the control plate 87 to the position shown in FIG. 6C. Then, the first hole 88 overlaps with the third gas hole 79 of the upper burner member 72, and the second hole 89 overlaps with the third gas hole 84 of the lower burner member 81. As a result, the upper burner portion 61 becomes low fire and the lower burner portion 62 becomes high fire.

  When the fourth combined heating amount is generated by the grill burner 6, the control unit 13 drives the motor 92 and moves the control plate 87 to the position shown in FIG. 6D. Then, the first hole 88 overlaps with the fourth gas hole 80 of the upper burner member 72, and the second hole 89 overlaps with the fourth gas hole 85 of the lower burner member 81. As a result, the upper burner portion 61 has a low fire and the lower burner portion 62 has a low fire.

  In the grill device 1 of the present embodiment, the upper burner unit 61 has a heating amount of 750 kcal / h (872 W) during a strong fire, a heating amount of 650 kcal / h (756 W) during a low fire, and the lower burner unit 62 has a strong fire. The heating amount at the time is 1250 kcal / h (1454 W), and the heating amount at the low heat is 300 kcal / h (349 W).

  That is, even with the same fuel gas supply amount, the change in the heating amount is greater in the lower burner portion 62 than in the upper burner portion 61. That is, according to the grill device 1 of the present embodiment, the amount of heat applied to the grill warehouse 31 can be greatly changed by adjusting the heating power of the lower burner portion 62.

  Regarding this point, the reason why the adjustment range of the heating power of the lower burner portion 62 is wide is that the stove burner is diverted as the lower burner portion 62. Moreover, the cooking container 4 and the to-be-cooked object can be effectively heated by having comprised the bottom center part of the cooking container 4 with the lower burner part 62 being heated. Thus, since the calorie | heat amount given to the grill store | warehouse | chamber 31 can be changed greatly and the cooking container 4 and a to-be-cooked item can be heated effectively, it can be set as the grill apparatus 1 which is easy to use.

  When the upper burner portion 61 and the lower burner portion 62 are extinguished, the motor valve 7 is driven and the control plate 87 is moved to the position shown in FIG. 6E. As a result, the first hole 88 and the second hole 89 are closed by the closing portion 73. Further, when only one of the upper burner portion 61 and the lower burner portion 62 is extinguished and the other combustion is continued, the supply of fuel gas to the burner portion to be extinguished is shut off by the closing valve 68.

  Further, the control plate 87 of the motor valve 7 does not move according to the pitch of the gas holes 74 but moves at an interval smaller than the pitch of the gas holes 74. As a result, the flow rate of the fuel gas can be controlled more finely.

  By the way, in such a grill apparatus 1, if not used for a long time, the temperature of the apparatus itself is lowered, and there may be a cold start at the start. In this case, the combustion rate tends to decrease, and combustion tends to become more unstable than usual. For this reason, when the second member 86 is driven at a high speed immediately after the start of the start to rapidly change the amount of fuel gas supplied to the grill burner 6, blowout due to a lifting phenomenon or the like is likely to occur.

  On the other hand, in the grill device 1 of the present embodiment, when changing from the ignition heating amount to another heating amount, the driving speed of the motor 92 is reduced compared to other times (that is, normal time). It is configured to perform control. Thereby, the grill apparatus 1 of this embodiment can prevent the combustion failure at the time of starting.

  When the ignition heating amount is ignited by operation of the operation unit 5 or automatic cooking, the control plate 87 moves from the state of FIG. 6E to a state in which fuel gas is supplied (for example, FIG. 6A). The combined heating amount at the position moved to. In addition, after moving from the heating amount at the time of ignition, when it is set to the same heating amount as the heating amount at the time of ignition again, this is not called the heating amount at the time of ignition.

  In the grill device of this embodiment, the heating amount at the time of ignition is a combined heating amount (the combined heating amount combining the largest heating amount of the upper burner portion 61 and the largest heating amount of the lower burner portion 62 among the four sets of combined heating amounts ( The heating amount in the state of FIG. 6A) is set. That is, the ignition heating amount in the present embodiment is set to the first combined heating amount. The ignition heating amount may be arbitrarily set by the user.

  If the combustion of the grill burner 6 continues, the temperature of the apparatus rises, so that variations in the air-fuel ratio hardly occur and the combustion is stabilized. At this time, if the driving speed of the motor 92 is reduced, the responsiveness of changing the heating amount is affected, and the user's usability is deteriorated.

  For this reason, the grill device 1 of the present embodiment is controlled so as not to suppress the driving speed of the motor 92 in the operation of changing the heating amount other than when changing from the ignition heating amount to another heating amount. .

  The drive speed of the motor 92 is controlled, for example, by adjusting the switching speed of pulses of drive power supplied to the motor 92 (stepping motor). In the grill device 1 of the present embodiment, the electric power supplied to the motor 92 is set to 333 PPS when the pulse frequency is normal, and is set to 143 PPS when changing from the heating amount during ignition to another heating amount. The

  As shown in FIG. 1, the grill device 1 is provided with an operation unit 5 for operating the stove unit 2 and the grill unit 3. The grill device 1 according to the present embodiment includes, as the operation unit 5, a stove operation unit 5 a that operates the stove unit 2 and a grill operation unit 5 b that operates the grill unit 3. The stove operating portion 5 a is provided on the front side of the top plate 21. The grill operation unit 5 b is provided on the front surface of the main casing 11 so as to be freely housed. The operation unit 5 gives the control unit 13 a control command for switching the ignition / extinguishing of the stove unit 2 or the grill unit 3 and adjusting the thermal power.

  As shown in FIG. 7, the grill operation unit 5 b includes switches such as a menu changeover switch, a cooking mode changeover switch, a fire adjustment changeover switch, a point fire extinguishing switch, a timer switch, and a cancel switch.

  With respect to the menu set by the menu switching switch, the cooking finish can be adjusted by the heating / discharging switching switch. In addition, this "fire control" means, for example, the strength of the burnt, and the fire control in cooking is automatically controlled by the control unit 13.

  As described above, the grill device 1 of the present embodiment includes the following first feature. In the first feature, a grill warehouse 31, a grill burner 6, a motor valve 7, and a control unit 13 are provided. The grill burner 6 is provided in the grill warehouse 31 and heats the food to be cooked in the grill warehouse 31. The motor valve 7 changes the gas supply amount to the grill burner 6 by driving the motor 92, and thereby changes the heating amount of the grill burner 6. The control unit 13 controls driving of the motor 92. The control unit 13 changes the driving speed of the motor 92 when changing the heating amount during ignition of the grill burner 6 from another heating amount, and when changing the other heating amount (that is, the normal driving speed of the motor 92). Is also controlled to be slow.

  According to the grill device 1 having the first feature, at the time of start-up in which combustion is likely to be unstable, the driving speed of the motor 92 is reduced, so that blow-off can be prevented. Furthermore, according to this grill device 1, since the drive speed of the motor 92 is controlled only at the start time, it is possible to suppress the deterioration of the responsiveness of the operation.

  Moreover, it is preferable that the grill apparatus 1 has the 2nd-4th characteristic shown below. The second to fourth features are not necessarily required for the present invention, but are arbitrary configurations.

  In the second feature, in the first feature, the grill burner 6 includes an upper burner unit 61 that heats the food in the grill box 31 from above, and a lower burner that heats the food in the grill box 31 from below. Part 62. The motor valve 7 includes a first member 71, a second member 86, and a motor 92. The first member 71 is provided with a plurality of gas holes 74 corresponding to a combined heating amount obtained by combining one heating amount of the upper burner portion 61 and one heating amount of the lower burner portion 62. The second member 86 has a first hole 88 through which a gas to be supplied to the upper burner part 61 flows and a second hole 89 through which a gas to be supplied to the lower burner part 62 flows. The motor 92 drives the first member 71 or the second member 86. The motor 92 selectively communicates the first hole 88 and the second hole 89 with one set of gas holes 74 among the plurality of sets of gas holes 74 of the first member 71.

  According to the grill device 1 having the second feature, it is possible to control the upper burner portion 61 and the lower burner portion 62 with high responsiveness while preventing blowout.

  In the third feature, in the second feature, the grill warehouse 31 has a cooking container 4 that can be freely pulled out and stored. The lower burner part 62 heats the bottom center part of the cooking vessel 4. The heating amount at the time of ignition is set to a combined heating amount obtained by combining the largest heating amount of the upper burner portion 61 and the largest heating amount of the lower burner portion 62 among a plurality of combined heating amounts.

  According to the grill device 1 having the third feature, since the lower burner portion 62 heats the bottom center portion of the cooking vessel 4, the cooking vessel 4 is easily affected by the change in the heating amount of the lower burner portion 62. .
