Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker such as an electromagnetic induction heating cooker in which a cooking surface is composed of a flat plate such as a ceramic plate. It is such a thing.

2. Description of the Related Art Conventionally, an induction heating cooker has been invented in which a part of a glass plate made of ceramic or the like, which is a cooking surface, is made transparent and a display portion is provided on the back surface in that part in this kind of heating cooker. As described above, in the case where the pot itself generates heat, the position of the display unit and the display method are greatly restricted in order to suppress the heat influence on the display unit.

Problems to be Solved by the Invention Particularly, in the case of using multiple LED lamps as display lamps, a drive circuit composed of a dedicated IC or transistor is required to sequentially light these LED lamps. , In order to protect these circuits from the heat effect from the above pot, we had to give great consideration to the installation location and heat shield method.

In view of the above problems, the present invention provides a display device for a heating cooker which suppresses the heat effect from a pan and has an inexpensive and simple heat shield structure.

Means for Solving the Problems The present invention is arranged below the transparent hole and extends one side of a display case for accommodating an LED lamp or the like toward a heating unit,
Radiant heat and conductive heat from the pan are shielded, and semiconductor parts for driving the LED lamps are arranged in the shielded portion.

Action The present invention is capable of efficiently shielding the display unit by the above means and reducing the cost required for the shielding.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, 1 is a body case of an induction heating cooker, 2 is a
A top plate made of a transparent ceramic, the back surface of which is printed with a heat-resistant coating film 3, and has a through hole portion 4 for displaying a part. Reference numeral 5 denotes a frame body that fixes the top plate 2 to the main body case 1 and forms a pot mounting space. Reference numeral 6 is a control knob for controlling ON / OFF of the power supply and output.

In FIGS. 1, 3, and 4, 7 is a pot and 8 is a heating coil. Reference numeral 9 denotes the display device placed under the through hole portion 4, which is an LED case 11 made of a heat-resistant resin, which is integrated with a plurality of LED lamps 10 and protects the LED lamps 10 from the influence of heat from the outside. , And a semiconductor lighting circuit 12 composed of an IC and a transistor for sequentially lighting the LED lamps. Here, one side of the upper surface of the LED case 11 is a flange body 13 protruding toward the heating coil 8 side.
And a component 12a of the semiconductor drive circuit 12, which is particularly susceptible to temperature, such as an IC and a transistor.
Is placed below it.

Now, in the heating cooker having the above configuration, when the pan 7 is placed on the top plate 2 and the heating is started, the bottom surface of the pan 7 generates heat, and the radiant heat is also applied to the inside of the main body case 1 through the top plate 2, Causes a temperature rise. Particularly, in the case where the display portion 9 is directly provided on the lower portion of the top plate 2 as in this configuration, it is easily affected by the heat. However, in this configuration, since the flange 13 is formed on the upper surface of the LED case 11, heat from the pot 7 is prevented from being transferred to the semiconductor lighting circuit 12. The pot 7 of this embodiment is a circular pot, but in a large-sized pot such as an teppanyaki pot, since the pot is close to the display part, the effect of heat shielding is greater.

EFFECTS OF THE INVENTION As is clear from the above description, according to the present invention, by extending one side of the case forming the display portion located in the lower portion of the top plate in a flange shape, the heat of the semiconductor circuit component etc. of the display lamp lighting is increased. The shield can be constructed at a very low cost and easily, and as a result, it becomes possible to easily select the mounting location of the display unit and to reduce the mounting space for mounting the display unit at high density.
