Description

  The present invention relates to a cooking device.

  In a conventional cooking device, for example, “a power switch that opens and closes by operating a power switch operation unit with a predetermined force or more and that enables and disables the control command according to the opening and closing operation. The power switch operation unit is arranged on the side surface of the top frame "(for example, see Patent Document 1).

  Further, for example, “the power switch operation unit is arranged on the upper surface in the vicinity of one of the left and right corners on the user side of the top unit, closer to the corner than any of the operation keys, and the individual operation There has been proposed "a power switch identification display section that forms a step on the top plate upper surface between the switch section and the power switch operation section" (see, for example, Patent Document 2).

  Further, for example, “the operation knob 11... Starts to energize the induction heater coils 3, 4, the radiant heater 5 and the grill heater (not shown) in the grill 7 when pulled out by a push operation, and stops operation when pulled in. It is configured to set the heating power, cooking time, cooking temperature, etc. when it is rotated at the position. "(For example, see Patent Document 3).

Japanese Patent No. 4135718 (Claim 1) Japanese Patent No. 4251140 (Claim 1) JP 2008-71550 A (paragraph [0011])

In the cooking device of the said patent documents 1 and 2, it is set as the structure which reduces a push difference with a power switch which invalidates the control instruction | command of a several separate operation switch and all the separate operation switches.
However, during operation of a plurality of heating means, for example, when blown down occurs and it is desired to stop the heating immediately (hereinafter referred to as “emergency”), when the power switch is operated, there is no other need to stop. There was a problem that the operation of the heating means also stopped.
Also, among the multiple individual operation switches, it is difficult to distinguish between the switch that stops heating and the other switches, so if you try to stop heating with an individual switch in an emergency, you may get lost or push the operation. There was a problem that there was.

In the heating cooker of the above-mentioned patent document 3, a push type operation knob is provided for each heating means on the front surface of the main body, and when the operation knob is pushed in, the operation of the heating means is stopped.
However, when a push-type operation knob is provided, there is a problem that the number of parts increases and the structure becomes complicated, resulting in an increase in cost.
In addition, since the operation knob is provided on the front surface of the main body, it is difficult for the user to see the operation knob, and the user needs to operate by groping or bending the front panel. For this reason, there has been a problem that it is difficult to perform an immediate operation in an emergency and an erroneous operation may occur.

  The present invention has been made to solve the above-described problems, and provides a cooking device capable of improving the usability of an operation for stopping cooking.

The cooking device according to the present invention includes a top plate on which an object to be heated is placed, a plurality of heating means disposed below the top plate, and an operation for inputting a setting operation and a heating stop operation related to heating control. Each of the heating means is provided for each of the heating means, and each of the heating means is provided with a switch having a cutting function for stopping the heating cooking by the corresponding heating means. One or a plurality of operation switches for performing a setting operation related to control, and at least a part of the operation switches are arranged on the top plate and in front of the heating means in one or more rows, switch with the switching function, a said top plate, the front side of the heating means corresponding, and, in front of the sequence of the operation switch, the The sequence of the created switches spaced, on the front side of the operation switch is to only switches with the switching function is located.

  According to the present invention, since the off switch provided for each heating means is arranged on the top plate on the front side of the corresponding heating means and on the front side of the operation switch arrangement, the operation for stopping the cooking is performed. Usability can be improved.

For this reason, it becomes easy to visually recognize the cut-in switch 51, and it is possible to reduce the ambiguity and erroneous operation. Therefore, the usability of the operation for stopping the cooking can be improved.
In addition, it becomes easy to distinguish between the operation switch and the cut-in switch 51, and it is possible to reduce the ambiguity and erroneous operation.
In addition, since each cutting switch 51 is arranged on the front side of the corresponding heating means, the relationship between the cutting switch 51 and the heating means to be operated is easy to understand, and usability can be improved.
In addition, since the cut-in switch 51 is disposed further in front of the operation switch arrangement, the cut-in switch 51 can be visually recognized independently, and the cut-off switch 51 and other operation switches can be clearly distinguished visually. it can. Therefore, it is possible to reduce the possibility of losing operation or pushing the button in an emergency.
Moreover, since the cut-in switch 51 is disposed on the front side closest to the user on the top surface of the top plate 2, it is easy for the user to visually recognize the cut-in switch 51, and it is possible to reduce operation mistakes and erroneous operations. Further, the user can easily operate the cut-in switch 51, can perform an immediate operation in an emergency, and can reduce erroneous operations.
Further, as compared with the case where the operation switch and the cut-in switch 51 are arranged in the same arrangement, the interval between the operation units (right IH operation unit 5R, left IH operation unit 5L, grill operation unit 5G) for each heating unit is increased. Therefore, the correspondence between each operation switch and the heating means can be understood more clearly, and usability can be improved.
In addition, the manufacturing cost can be reduced as compared with the case where a push-type operation knob is provided on the front surface of the main body 1.
Moreover, since the cut-in switch 51 is disposed on the top surface of the top plate 2, it can be easily recognized by the user, can be operated immediately in an emergency, and can reduce erroneous operations.
Moreover, since the cut-in switch 51 is provided for each heating means, heating cooking by a desired heating means can be stopped.

Further, at least a part of the main power switch 50 is disposed at a position corresponding to the position in the depth direction of each cutting switch 51.
For this reason, the arrangement position of the switch with which the operation regarding a heating stop is common can be matched, and the usability of the operation to stop the heating cooking can be improved.
