DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an induction heating cooker.

[0002]

2. Description of the Related Art In a conventional induction heating cooker, a display for displaying an operation state is mainly provided in a vertical operation panel disposed on a front surface of a main body. The display contents of this display unit include the thermal power during the basic operation, the oil temperature during the cooking of fried food such as tempura, the timer remaining time during the timer operation, and the like.

When an induction heating cooker is installed in a general home kitchen, its vertical position is 60 to 70 centimeters from the floor.
This is the m-th position. When the user stands and uses the induction heating cooker before this, the position of the user's face, that is, the position of the eyes is about 140 to 170 cm.

[0004] For this reason, it is difficult to confirm the displayed contents even when looking from above, in order to confirm the driving state and the like displayed on the operation panel while cooking. Therefore, it is impossible to confirm the condition without bending the body and bringing the face close to the front of the operation panel, or looking into the operation panel from a place away from the main body.

[0005] Therefore, such an induction heating cooker is very inconvenient and has poor operability because the posture must be changed greatly every time the operating state or the like is checked.

[0006] In order to solve the above-mentioned problem, an induction heating cooker in which a display of a thermal power is provided on a top plate surface has been commercialized.

In an example of the configuration, a plurality of LEDs or lamps are turned on, and the magnitude of the thermal power is displayed by the number of the turned-on LEDs or lamps. Also, the oil temperature at the time of cooking fried food such as tempura is displayed in substantially the same manner.

An example of such a conventional example is disclosed in
No. 1-2412, and the like.

[0009]

As described above, in the conventional induction heating cooker, the display method of the heating power is the LED.
10 in a row, and the thermal power is full power (ie, 100
%), 10 lights are turned on, and when the thermal power is 50%, 5 lights are turned on, 5 lights are turned off, and so on. However, when the LEDs are small in shape and are continuously arranged, it is difficult to determine whether five or six LEDs are lit. In particular, this problem becomes remarkable when the user is an elderly person.

[0010] The method of displaying the oil temperature when cooking fried food such as tempura has the same problem as the method of displaying the thermal power.

There is also a display having a display for displaying the remaining time of the timer during the timer operation. The display is located in the operation panel on the front vertical surface of the main body and has only one timer. It is. For this reason, the operability is poor, and even if a plurality of induction heaters are provided, a plurality of induction heaters cannot be simultaneously operated by a timer.

Further, in the case of an induction heating cooker in which a display such as heat power is provided on the top plate surface, the display structure is often arranged near the induction heater below the top plate. There is an inherent problem that the reliability is difficult because the surrounding area becomes extremely hot.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to make it easier to see indications such as the heating power during basic operation, the oil temperature during cooking of fried food such as tempura, and the timer remaining time during timer operation. Is what you do.

In the case of an induction heating cooker having a plurality of induction heaters, the timer operation of the plurality of induction heaters can be simultaneously performed.

Further, even in the case of an induction heating cooker in which a display such as heat power is provided on the top plate surface, the temperature of the display structure is prevented from becoming high.

[0016]

In order to solve the above-mentioned problems, the present invention provides a top plate disposed on an upper surface of a main body, and a plurality of induction heaters disposed below the top plate and heating a load. Induction heating cooking, comprising: a transparent display unit provided on the top plate surface; and a display structure unit disposed below the display unit and displaying an operation state or a setting state for operation of the induction heater. In the container, the display structure portion is a number,
The structure is such that all or a part of characters and graphics are combined and displayed.
