Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an induction heating cooker, and more particularly to an arrangement for visually distinguishing a plurality of stoves having different rated outputs.

[0002]

2. Description of the Related Art Conventionally, an induction heating cooker of this type is not required to emit a flame and has a high thermal efficiency as compared with a gas range, so that the demand thereof has been increasing. FIG. 5 is a perspective view of a conventional general induction heating cooker. In FIG. 5, 1 is a main body case, 2 is a top plate on which a cooker is placed, and 3 and 4 are heating units provided with the same rated output by induction heating. Yes, it is. Numeral 5 is a radiant heater which is used when heating with an aluminum pot or copper pot which cannot be used for induction heating.

[0003] In the case of performing induction heating cooking with the induction heating cooker configured as described above, a cooking container capable of induction heating is placed on the heating unit 3 or 4 on the top plate, and the power is turned on. It has been done.

[0004]

However, in the conventional induction heating cooker, a plurality of heating sections all use the same rated heating coil. For example, in the figure, there are two heating units, and the corresponding rated output of the heating coil is 2 kW.
Met.

[0005] However, in recent years, with the diversification of cooking, heating units having different outputs, particularly those having large outputs, have been desired. In view of the above, an object of the present invention is to provide an induction heating cooker having heating coils having different ratings, that is, heating portions having different inputs and outputs.

[0006] However, even if the output of the heating section is different, the induction heating cooker cannot distinguish it. In the conventional induction heating cooker, when the container to be heated is placed on both of the heating units, or when either one of the containers is selected and placed, the container may be placed on any heating unit.

However, if the output of the heating unit is different, there is a problem that if the selection of the heating unit is incorrect, the scheduled cooking time is deviated, or the temperature is too high, resulting in poor cooking finish.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide an induction heating cooker capable of recognizing a difference in output with a simple configuration.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a graphic for visually distinguishing a difference in rated output from a heating section on a top plate on which a container to be heated is placed. The display that changes the size of a figure, the number of figures, or the color of a figure is added.

[0010] By displaying the difference in the output based on the difference in the graphic as described above, the heating unit can be easily selected.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the above-mentioned problems, the present invention provides a heating unit provided on a top plate on which a cooking container is placed and heated by induction heating, and the heating unit provided below the top plate. A plurality of heating coils having different rated outputs provided corresponding to the portions, and a light emitting means for emitting a light beam, wherein the light emitting means is formed on the top plate in a shape such that the difference in the rated output can be visually distinguished. Added display.

More specifically, the difference in the rated output is indicated by the difference in the size of the figure, the difference in the width of the figure, the difference in the number of figures, and the difference between a single figure and double or more figures.
Alternatively, the difference in the rated output is displayed using at least one of the difference in the color of the figure or the difference in the shade of the color.

The rated output of the heating section can be easily distinguished visually by such a difference in the figures.

Further, the display graphic is displayed using at least one of a point, a straight line, and a polygon.

Since the figure is simple, the structure of the light emitting means required for display can be simplified.

When two heating coils are provided, only one of them is displayed as a graphic. This makes it easy to distinguish the rated output.

Further, the light emitting means is turned on during cooking, and is turned on and off until the temperature of the top plate becomes lower than the dangerous temperature after cooking is completed. With this configuration, the progress of cooking can be easily grasped.

[0018]

Embodiments of the present invention will be described below with reference to the drawings.

The top plate used in the present invention may be translucent or non-translucent. However, in the case of non-transparency, the portion corresponding to the top plate figure must be translucent. The method can be achieved by applying a black inorganic paint to the lower surface of a translucent glass or the like constituting the top plate, and not applying the inorganic paint only to a portion requiring translucency. . Hereinafter, a case where a translucent top plate is used in the present embodiment will be described.

In this embodiment, as an example of a plurality of heating coils having different rated outputs, the rated outputs are 2 kW and 3 kW.
In the description, it is assumed that a heating coil of 2 kW is arranged on the left side and a heating coil of 3 kW is arranged on the right side.

The structure of the induction heating cooker according to the present invention and the structure of the conventional induction heating cooker are almost the same in the main part, and the difference is particularly in the method of displaying the heating section displayed on the top plate. is there. Therefore, the same components as those of the present invention and those of the related art are denoted by the same reference numerals, and description thereof is omitted.

Further, the display on the top plate is a display in which the light emitted by the light emitting means provided below the top plate is viewed from above the transparent top plate (display means on the top plate), and the figure is the light emitting means. It almost matches the configuration. However, since the present invention is intended to clarify the difference between the displays, the description of the light emitting means is only an outline.

(Embodiment 1) FIG. 1 is a perspective view of an induction heating cooker according to Embodiment 1 of the present invention. In the figure, the left side is rated output 2
The heating unit 6 corresponding to the heating coil of kW, and the right side is the heating unit 7 corresponding to the heating coil of the rated output of 3 kW.
In this embodiment, the difference in the rated output is indicated by the size of the figure, which is indicated by a circle surrounding the heating unit. The circle corresponding to the rated output of 3 kW was larger than the radius of the circle corresponding to the rated output of 2 kW. This makes it easy to visually determine which output is greater.

In the above embodiment, a circle is used as a figure.
In addition, it may be a polygon such as a quadrangle surrounding the entire heating unit, or a part of a circle or a polygon.

Further, since the size of the figure only needs to be large enough to discriminate the difference in the rated output, the size is not necessarily required to be large enough to surround the heating section. It is preferable that the size is of the order of magnitude because the difference in the rated output can be determined even after the heating cooking container is placed on the top plate, or during heating or cooking.

Also, although the shape surrounding the heating section is shown as a figure, the cost may be increased. Therefore, it is possible to use a line to make a distinction based on the length of the line. It may be displayed as a point. However, when displayed as a line or a point, it becomes more difficult to discriminate as compared to a case where the periphery of the heating unit such as a circle is surrounded.

(Embodiment 2) FIG. 2 is a plan view showing only a heating section which is a main part of an induction heating regulator according to Embodiment 2. In the figure, the width of the circumference of the heating unit 8 corresponding to the heating coil with a rated output of 2 kW is the heating unit 9 corresponding to the heating coil with a 3 kW rating.
It is narrower than the width of the circumference. This makes it possible to easily determine the difference between the outputs.

Further, as in the first embodiment, the figure is not limited to a circle. Even when a line is displayed, it can be identified by a thin line having a large line width. Further, even when a point is displayed, it is possible to make a determination based on the size of the point. Further, the concept of the graphic display of the first embodiment is applied to the second embodiment.
Of course, the concept of the graphic display may be added.

(Embodiment 3) FIG. 3 is a plan view of a heating section which is a main part of an induction heating cooker according to Embodiment 3. In FIG. 3, the figure of the heating unit 10 corresponding to the rated output of 2 kW is indicated by one circle, and the figure of the heating unit 11 corresponding to the rated output of 3 kW is indicated by two concentric circles. This makes it easy to visually determine the difference between the outputs. Similarly, when the heating section is surrounded by a polygon, it is preferable to concentrically arrange congruent figures having different sizes on one side and the other on the other side. In the case of displaying using lines and points, it can be determined by changing the number of lines and the number of points.

Further, it goes without saying that the concept of graphic display of the first or second embodiment may be added to the concept of graphic display of the present embodiment.

(Embodiment 4) In Embodiments 1 to 3 described above, differences in rated output are displayed as differences in figures.

In this embodiment, the rated output is determined based on the difference in the color of the figure. For example, a heating unit corresponding to different rated outputs is displayed in circles of the same size, a heating unit with a rated output of 2 kW is displayed in blue, and a heating unit with a rated output of 3 kW is displayed in red. Alternatively, the same color may be used to display the heating section with a rated output of 2 kW in pale red, and the heating section with a rated output of 3 kW in dark red to use the shade of color.

As a method of coloring the display, the use of a colored light source in which the color of the jacket of a rod-shaped heating element such as a light bulb or a fluorescent lamp is colored, or the use of a filter can provide a desired color and color shading. You can choose.

As a method of coloring the display surrounding the heating section like a circle, as shown in FIG. 4, a colored light source having a colored outer jacket of a ring-shaped light emitting means such as a fluorescent lamp, or a donut-shaped A light emitting means 13 may be provided at the center of the light guide plate 12, and the light of the light emitting means 13 may be guided by the light guide plate 12 and emitted in an annular shape around the light guide plate 12, and a circle may be displayed on the top plate. At this time, a color light source may be used as the light source. Alternatively, a color light guide plate may be used as the light guide plate. There is also a method in which a light-emitting paint that emits light when irradiated with light is applied in advance under the top plate, and the light-emitting paint is illuminated.

(Embodiment 5) In the first to fourth embodiments, a case has been described in which a graphic is displayed for each heating unit in the heating units having different rated outputs. However, when there are two induction heating units, only one of them may be displayed. The display of the graphic may be performed according to the first to fourth embodiments.

As described above, as described in the first to fifth embodiments, the difference in the rated output can be displayed by the shape of the figure and various colors. Of course, the display is not limited to the above-described embodiment, and the display can be appropriately changed by a point, a straight line, a circle, a polygon, a part of a circle or a polygon, and a combination of various colors. For example, the radius of a circle with a rated output of 3 kW may be larger, wider, and displayed in a different color than a circle with a rated output of 2 kW. In this case, the inside of the heating unit may be used as a surface, and the surface may be distinguished by a difference in surface light emission.

As described above, in the present invention, the light emitting means is provided below the top plate, and the light emission of this light emitting means is displayed on the top plate. , There is also a method of distinguishing. However, when a figure is drawn on the lower side of the top plate, the reflected light of the light incident from the upper surface is viewed, and there is a problem that the thickness of the top plate is so large that it is difficult to see. Further, when drawing a figure on the top plate, it is necessary to consider wear due to friction with the container to be heated.

In this embodiment, the case where there are two heating parts has been described. However, it is needless to say that more than two heating parts may be used, and the number of heating parts is large and the rated output of the heating coil is largely different. The more the effect of the present invention increases.

Although the case where the planned output is 2 kW and 3 kW has been described, the present invention is not limited to this, and the rated output may be smaller or larger. Of course, a small heating section may be provided on the right side.

Since the induction heating cooker generally has a temperature detecting means and a control means, these are utilized. When the figure of the present invention is lit during cooking, the temperature of the top plate becomes lower than the dangerous temperature after the cooking is completed. Flashes until it lights up,
The display method may be changed for each function such as “during fried food”.

[0041]

As described above, according to the present invention, the difference in the rated output of the heating coil is graphically displayed on the heating portion on the top plate by the light emitting means, so that the difference in the rated output can be easily visually recognized. Since the heating unit can be selected according to the type or amount of cooking, cooking can be performed appropriately.
