Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a stationary or built-in induction heating cooker used in a general household kitchen or a commercial kitchen.
[0002]
[Prior art]
Conventionally, this type of induction heating cooker has a control circuit in which an operation unit is arranged on a front surface of a main body, a signal input unit for controlling operation of the device, and a display unit for displaying an operation state of the device. The operation unit unit included was generally attached to a part of the outer shell of the main body from the inside by a fastening means such as a screw (for example, see Patent Document 1).
[0003]

Japanese Patent Application Laid-Open No. 2002-213755
[Problems to be solved by the invention]
However, in such a conventional configuration, since the operation unit is located on the front surface of the main body, it is difficult to operate switches for operation control and to confirm an operation state, which is not convenient.
[0005]
In some cases, the operation unit housed in the front part of the main body is slid or rotated so that the operation surface thereof faces upward, but the configuration becomes complicated, and when used, it protrudes greatly to the front of the main body. For this reason, it becomes an obstacle during work other than the operation.
[0006]
In addition, there is a part in which a partial operation / display function is provided on the top surface of the main body, but the main operation / display section is arranged in front of the main body. This is because the top surface of the main body is originally made of a material that is not heated by electromagnetic induction, such as a high heat-resistant glass, in order to place the object to be heated, ie, the top plate, This is because the surroundings are generally made of a frame made of a metal such as stainless steel, which sufficiently withstands the heat from the object to be heated, has a good appearance as an exterior, and is resistant to corrosion.
[0007]
In other words, if you try to arrange a full-fledged operation unit on the top surface of the main unit that integrates almost all operation and display functions, the part corresponding to the operation unit of the main unit will be complicated, so processing with metals such as stainless steel It becomes difficult.
[0008]
In addition, with the conventional configuration, when assembling the operation unit, the main unit is turned upside down and the components are incorporated, so the surface of the main frame is easily scratched, and the appearance quality may be impaired and it may be defective. Was to become larger.
[0009]
SUMMARY OF THE INVENTION The present invention solves such a conventional problem. When most of various operation / display functions are arranged on a top surface of a main body, the present invention is easy to assemble and is capable of greatly reducing appearance defects and the like. It is intended to provide a cooking device.
[0010]
[Means for Solving the Problems]
In order to solve the conventional problem, an induction heating cooker according to the present invention includes a main body, a top plate on which a cooker is placed, which is arranged on a top surface of the main body, and a top plate below the top plate. An induction heating coil provided, a power supply circuit for supplying high-frequency power to the induction heating coil, a control circuit for externally controlling the operation of the device and displaying the operation state of the device, and an operation unit for housing the control circuit An opening is formed in the top surface of the main body, and the operation unit is fitted to the opening from the inside of the main body and fixed to the main body.
[0011]
Thereby, the complicated shape of the operation unit can be relatively easily realized by using the operation unit, and the top surface is configured by fitting the operation unit to the opening from the inside of the main body and fixing the operation unit. Since there is no need to turn over the parts and assemble the components, there is almost no fear of damaging the appearance, and when arranging most of the various operation and display functions, it is easy to assemble and the appearance defects etc. can be greatly reduced. is there.
