  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 shows a schematic configuration of the induction heating cooker according to the first embodiment of the present invention.

  In FIG. 1, a top plate 2 on which a cooking utensil to be heated is placed is arranged on the top surface of the main body 1. The top plate 2 is made of a material that is not overheated by electromagnetic induction, such as highly heat-resistant glass. The top frame 3 surrounds the outer periphery of the top plate 2 and forms the upper surface of the main body 1 together with the top plate 2.

An induction heating coil 4 is provided close to the bottom of the top plate 2. The induction heating coil 4 is held by a coil base 5 and held at a predetermined position in the main body 1. High frequency power is supplied to the induction heating coil 4 by a power supply circuit 6. The induction heating coil 4 and the power supply circuit 6 are cooled by the ventilation of the cooling fan 7.

  The operation unit 8 disposed below the front part of the top plate 2 includes an output unit for displaying the operation state of the device and a control circuit 9 having a signal input unit for controlling the operation of the device by external operation. Is housed in the cover 10.

  A substantially annular light guide 11 made of a light transmissive material is fitted to the coil base 5, and the light incident portion 13 is irradiated with light by the first light source 12. A part of the irradiated light travels through the light guide 11 while being partially reflected upward. As a result, the top plate 2 is irradiated as annular light.

  The top plate 2 is printed with a transparent or translucent coating on the portion that receives the substantially annular light from the light guide 11, and the light can be visually observed through the top plate 2. This annular light is arranged substantially concentrically with the induction heating coil 4 and indicates the position where the cooked utensil is placed. In addition, in an induction heating cooker, the heat source part does not red heat during heating, and no flame is generated. Therefore, if the light guide 11 emits light only during heating, it can be easily discriminated at a glance whether the heating is in progress.

  Inside the outermost diameter of the induction heating coil 4 is disposed a temperature sensor 14 for detecting the temperature of the bottom of a cooking utensil such as a pan with infrared rays. It is arranged close to the back surface of the plate 2.

  In order for the temperature sensor 14 to correctly detect the temperature of the bottom of the cooking utensil, the cooking utensil needs to be placed on the sensing part 15 of the temperature sensor 14. A second light source 16 is built in close proximity to the sensing part 15, and a light emitting window 18 is located at a position close to the light receiving window 17 indicated by printing with a light-transmitting coating film provided on the top 2. Also shown by printing with a translucent coating.

  Accordingly, when enlightening and thorough in the instruction manual so that the light of the light emitting window 18 is concealed when placing the cooked utensil, the light receiving window 17 is naturally positioned below the bottom of the cooked utensil. The temperature can be detected accurately.

  The placement is limited by the placement position of the cooking utensil, such as the display of the placement position of the cooking utensil by the light guide 11 and the light emitting window 18 that displays the placement position of the temperature sensor 14. The light emission display is governed by the position of the induction heating coil 4.

  On the other hand, as shown in FIG. 2, the control circuit 9 of the operation unit unit 8 has a contact terminal that contacts the electrode unit 20 printed with conductive paint on the back surface of the operation button 19 printed on the surface of the top plate 2. 21 is provided, and at the time of product assembly, the electrode portion 20 and the contact terminal 21 are electrically connected. When the operation button 19 is touched by a person, a change in the capacitance is detected, and an input indicating that the operation button 19 has been operated is obtained to control the operation of the device.

  The output unit 22 which is a display unit for displaying the operation state of the device includes a third light source 23, a display sheet 24 on which light-transmitting characters and patterns are printed, and the third light source 23 and the display sheet 24. It consists of a holder 25 and the like, and the irradiation light of the third light source 23 passes through the characters and patterns of the display sheet 24 and reaches the surface of the top plate 2 and visually recognizes the operating state of the device by visually observing them. It can be done.

A translucent coating film 26 is printed on the back surface of the range including the display unit and the operation unit of the top plate 2 so that these lights are transmitted. Here, all of the operation buttons of the top plate 2 and the output unit provided in the 19 control circuit 9 are partitioned into a substantially rectangular shape by the light-projecting coating film 26, and the boundary of the section extends to the front end of the top plate 2 Arranged within an extended range 27.

  Thereby, the region where the cooked utensil is placed in the entire top plate 2 and the region where the display unit and the operation unit are arranged are clearly separated, thereby making it difficult to arrange the display unit and the operation unit on the top plate. When placing an empty baked frying pan, etc. on the top plate 2, the display area and the operation area are easy to understand visually. Prevention of placing a frying pan or the like can be achieved.

  Here, it is sufficient that the range 27 divided into a substantially quadrangular shape is defined in terms of appearance. For example, even if there is a range of another light-projecting coating film adjacent thereto, the hues of these coating films are different. good.

  FIG. 3 shows the fitting relationship between the top plate 2 and the top frame 3. The range 27 divided into a substantially quadrangle extends from the left and right ends to the left and right ends of the top plate 2 itself. It extends to the front edge of the top plate 2. As a result, it is easy to hide the printing end portion of the range 27 partitioned into a substantially rectangular shape in the top frame 3 that covers the outer periphery of the top plate, and it is possible to make defects such as finishing of the printing end portion inconspicuous. The quality can also be improved.

  In addition, since the translucent coating film in a range roughly divided into rectangles has a dark color such as black, it is easy to hide the display content on the display unit so that it is not visible when it is not needed, that is, when it is not emitting light. Thus, an easy-to-understand display unit and operation unit can be realized without the complexity.

  In the present embodiment, the operation button 19 is printed from the front surface of the top plate 2, but for example, a letter or the like is formed on the electrode portion 20 printed with a conductive paint from the back surface to transmit light therethrough. The operation buttons may be raised to hide the buttons when they are not needed, so that the complexity is eliminated, the usability is improved, and the design is excellent.

  FIG. 4 shows an area 28 divided into a substantially rectangular shape extending to the left and right ends of the top plate 2, whereby the printing end of the section is divided into one side 29 that forms a section with the placement area of the cooked utensil. Therefore, the inclination of the boundary due to printing misalignment becomes inconspicuous, and the appearance quality can be further improved.

  FIG. 5 shows a non-slip of the cooking utensil to be cooked from the surface side or damage to the top plate in a portion other than the arrangement portion of the display unit and the operation unit in the range 28 partitioned into a substantially rectangular shape. The dotted film group 29 is given. Thus, without impairing the design, the range in which the display unit and the operation unit are actually arranged can be visually recognized in the range 28 in which the interspersed coating film group 30 is not applied in the range 28 partitioned into a substantially square shape. In addition to being able to appeal, it is possible to eliminate the slipperiness of the cooking utensils over a wider range of the top plate 2 and to reduce damage to the top plate.

  As described above, the induction heating cooker according to the present invention eliminates the complexity of the display unit and the operation unit on the top surface, is excellent in design, and further reduces adverse effects on the control circuit below the top plate. Therefore, the present invention can be applied to a general cooking apparatus having a similar configuration, that is, a display unit and an operation unit on the top surface.
