  Conventional cooking devices generally have a roaster at the bottom of the stove (induction heating device or electric heater), but the stove and other equipment such as a roaster, range, oven, dishwasher The number of kitchens that combine (tableware washing and drying machines) is increasing. When other equipment is installed in the lower part of the stove unit, a power outlet for other equipment is required in addition to the power outlet for the stove unit, so that a plurality of power outlet constructions are required. In Patent Document 1, since power supply to the roaster and the heating coil or electric heater is switched, the roaster and the heating coil or electric heater cannot be used at the same time. Moreover, in patent document 2, since the electric power supply of an apparatus fell according to the electric power supply state of another apparatus, there existed a subject that it might interfere with cooking.

  The present invention has been made to solve the above-described problems of the prior art, and can reduce the number of power outlet constructions, can easily cope with various kitchen needs, and at least can be connected with other devices. One of the objectives is to obtain a kitchen cooking heater that can be freely adjusted by the user and does not exceed the allowable capacity of the power outlet.

  The heating cooker according to the present invention comprises a first heating means driven by a first drive circuit for heating a cooking utensil and a second heating means driven by a second drive circuit, and the first and An operation display unit for the second drive circuit, a control circuit for controlling the first and second drive circuits based on settings in the operation display unit, and a power input unit for receiving power from a power outlet In the built-in heating cooker, the power supply unit that can supply the power received from the power input unit to other devices, and the power that detects the amount of power supplied from the power supply unit to the other devices An amount detection means, and the control means supplies power to one of the first and second heating means so as not to exceed the allowable power of the power outlet according to the detection result of the power amount detection means. The control so as to decrease.

  In the present invention, since the power supply unit that can supply power to other devices is provided, it is not necessary to add power outlets for other devices, and the power supplied to the other devices can be supplied from the power outlet. When the control power exceeds the allowable power, the control means reduces the power supplied to one of the first and second heating means to protect the circuit, and the remaining drive circuit can continue arbitrary heating. The effect that there is no trouble to the is obtained.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a main configuration of an induction heating cooker with built-in kitchen that is a heating cooker according to Embodiment 1 of the present invention. In the figure, the electric power supplied from the power outlet plug 1 connected to the commercial power supply is supplied via a noise filter 2 to a first drive circuit 31 comprising an inverter, a second drive circuit 32 comprising a similar inverter, and, for example, The power is supplied to the power supply unit 4 including a service outlet for supplying power to other devices incorporated in the lower part of the kitchen as desired by the user, such as a roaster, a range, an oven, and a dishwasher. The power supply unit 4 is composed of, for example, a high-capacity outlet or a terminal block, and is provided at the lower part of the casing (not shown).

  The noise filter 2 is for preventing the noise generated by the induction heating cooker from leaking to the power outlet. The first drive circuit 31 composed of an inverter generates a high-frequency current that drives the first heating means 51 composed of an induction heating coil, and heats a load composed of a cooking utensil such as a metal pan (not shown). The second drive circuit 32 composed of an inverter generates a high-frequency current that drives the second heating means 52 composed of a similar induction heating coil, and similarly heats the load. The strength of heating to the load, that is, the amount of power supplied to the heating means 51 and 52 is controlled by the drive circuits 31 and 32. The first and second drive circuits 31 and 32 are connected via the control circuit 7 in accordance with setting information set for the operation display unit 6 provided on the upper front side of the casing or on the front surface of the housing (not shown). Controlled.

  The operation display unit 6 displays buttons for setting the heating amounts for the individual heating means 51 and 52 and operation information such as the output states of the first and second heating means 51 and 52. For example, a lamp such as an LED or a display (not shown) is provided. In addition, a power amount detection unit 8 including a current detection sensor is provided on the line branched to the power supply unit 4, and the control circuit 7 exceeds the allowable power of the power outlet based on the detection result of the power amount detection unit 8. In this example, control is performed so that the power supplied to the first heating means 51 is lowered. Even in this case, the second drive circuit 32 side can use the heating output in an arbitrary range of 0 to full power. It is configured as follows. Since other configurations are the same as those of the conventional apparatus, description thereof is omitted.

Next, the operation of the first embodiment configured as described above will be described. Note that other desired devices are connected to the power supply unit 4, and even if the outputs of the first and second heating means 51 and 52 are simultaneously set to full power, the current consumption of the other devices is within a predetermined range. In the above, it is assumed that the allowable power of the power outlet is not exceeded and the second heating means 52 can be used at full power even when other devices are operated at full power.
When cooking utensils are placed on the upper portions of the first heating means 51 and the second heating means 52, respectively, and the heating output is set by the operation display section 6, the operation display section 6 outputs the output adjustment information from the user to the control circuit. 7 and the output states of the first and second heating means 51 and 52 are displayed. The output of the first heating means 51 and the second heating means 52 is adjusted with desired power by the control circuit 7 controlling the first drive circuit 31 and the second drive circuit 52 separately.

  The control circuit 7 monitors, for example, current supplied to other devices connected to the power supply unit 4 by the power amount detection means 8. For example, when there is no power supply to other devices, that is, power amount detection. When the signal detected by the means 8 is zero, the control circuit 7 sets the first and second drive circuits 31 and 32 based on the output adjustment information from the user within an arbitrary range of 0 to full power. Control. On the other hand, when there is power supply to other devices, the control circuit 7 controls the first drive circuit 31 so as not to exceed the allowable power of the power outlet, and reduces the output of the first heating means 51, The operation display unit 6 displays that the output has decreased, and notifies the user. At this time, since the second drive circuit 32 can be controlled within an arbitrary range of 0 to full power, it is possible to avoid troubles in cooking.

  With the diversification of kitchen needs, other appliances combined with the stove section are diversifying, and the power supply state is diverse. However, according to the first embodiment, with the configuration as described above, even if another device is connected to the power supply unit 4, the allowable power of the power outlet is not exceeded. Also, there is a second heating means 52 that allows the user to freely adjust the output at any time, and even if power is supplied to other equipment, the second heating means 52 can be used freely at the same time. Hard to occur. For example, the fish is baked in a roaster, which is another device, and the first heating means 51 is used to perform a stewed dish that does not interfere with low heating power. It is possible to stir-fry at the same time. In addition, since the power supply unit 4 for other devices is provided at the lower portion of the stove unit, it is not necessary to construct a power outlet for other devices and can easily cope with various kitchen needs. In addition to the current detection unit, a voltage detection unit may be used as the power amount detection unit 8.
