Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coating film configuration on a top plate on which a cooking container is placed.
[0002]
[Prior art]
Conventionally, there exists a thing as shown in FIG. The figure shows a so-called three-mouth cooking device having three heating units used in a kitchen in a general Japanese home.
[0003]
On the upper surface of the main body 1 constituting the outline of the heating cooker, a heat-resistant glass top plate 2 is disposed with its outer peripheral portion covered by a top frame 3. On the lower surface of the top plate 2 in the main body 1, a heating means 4 including an induction heating coil for performing induction heating, an electric heater, a halogen heater, or the like is disposed. On the surface of the top plate 2, the heating means 4 is disposed. The heating part 5 is provided corresponding to the provided position. On the front surface of the main body 1, there are provided an operation unit 6 of a fixed type such as a dial type or a push button type or an opening / closing storage type as shown in the figure, and a display unit 7 for displaying various states in accordance with the operation. A circular printing portion 8 is printed on the upper surface of the top plate 2 to indicate the position of the heating portion 5, and the whole or part of the top plate 2 has a stone shape, a spot shape, or a geometry to improve the design of the top plate 2. Pattern was printed with chromatic pigments. In addition, in recent years, many products equipped with the light emitting means 10 indicating the cooking state in the vicinity of the heating unit 5 have been commercialized.
[0004]
Conventionally, the color of the main body 1 is generally black and the most common, but in recent years, the needs for colorizing the main body 1 (for example, silver color) are increasing in accordance with the kitchen. The top plate 2 is also mainly black, but a chromatic color printing 9 (screen printing or the like) on the surface of the top plate 2 has been commercialized.
[0005]
Further, even in the case having the light emitting means 10, since 9 portions of the chromatic color printing are opaque or semi-translucent, the printed portion is partially removed to improve the light emission visibility.
[0006]
[Problems to be solved by the invention]
However, in the conventional configuration shown in FIG. 7, in order to produce a chromatic effect on the upper surface of the top plate 2, the chromatic color printing 9 must be applied over the entire surface. In addition, there is a problem that the printing part is easily soiled and the stains are easily noticeable while the cooking is repeated, and the stains are difficult to remove.
[0007]
Further, the light emitted from the light emitting means 10 indicating the state of cooking is projected to the user through a punched portion (for example, a transparent portion) that is not chromatically printed on the upper surface of the top plate 2, but when viewed from an oblique direction. There is a problem that the cooking state is difficult to recognize because the light emission is partially blocked.
[0008]
Further, in this way, only the portion facing the light emitting means 10 has been commercialized so that the chromatic color printing portion is not provided on the upper surface of the top plate 2 so that the visibility problem is improved. As a result, the glass becomes slippery and hinders cooking operations, and the glass surface of the top plate 2 is easily damaged.
[0009]
Furthermore, in order to solve the above-mentioned problem to the minimum, if the design 9 is not arranged only in the vicinity of the light emitting means 10 as much as possible, the light emission of the light emitting means 10 interferes with the design 9 when the main body 1 is viewed obliquely. There was a problem that visibility deteriorated or there was a problem in design and the merchantability was lowered.
[0010]
In order to solve these problems, when chromatic printing 9 is performed on the lower surface of the top plate 2, the heat diffusing agent (for example, silicon) of the sensor 11 attached to the main body 1 and pressed against the top plate 2 bleeds. If the chromatic color printing 9 is applied to the lower surface of the top plate due to the printing method, the coating film strength of the printing will be significantly reduced, resulting in damage to the appearance during assembly work and service. There was a problem.
[0011]
SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a cooking device having good appearance quality, high usability, and high reliability.
[0012]
[Means for Solving the Problems]
To achieve the object, a main body constituting an outer shell, a top plate provided on an upper surface of the main body, at least one heating unit provided on the top plate, and the heating unit below the top plate. Corresponding heating means and a light emitting means provided corresponding to the heating unit, the lower surface of the top plate is covered with a chromatic coating film with an upper layer as a chromatic base layer and a lower layer as a black film layer , A protective layer mainly composed of silicon is applied to the surface layer of the chromatic color coating film, and at least a part of the lower surface of the top plate facing the light emitting means has a translucent part not provided with the black film layer, and the translucent By providing the portions in the form of spots, the translucent portion and the built-in component are made less visible from the appearance .
[0013]
With this configuration, the thermal diffusion agent (for example, silicon) of the sensor attached to the main body and pressed against the top plate does not bleed and does not appear in the appearance of the top plate. Furthermore, the protective layer of silicon significantly improves the coating strength of chromatic color printing, so that it is not damaged during assembly work or service.
[0014]
In addition, the translucent part is hardly seen from the appearance, and the built-in parts can be prevented from being seen.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 corresponds to the main body constituting the outer shell, the top plate provided on the upper surface of the main body, at least one heating unit provided on the top plate, and the heating unit below the top plate.

[0021]
As shown in FIG. 1, a heat-resistant glass top plate 12 is disposed on the upper surface of the main body that constitutes the outline of the cooking device. A heating means 14 is disposed on the lower surface of the top plate 12 in the body. The lower surface of the top plate 12 is covered with a chromatic color coating film 22, and the surface layer of the chromatic color coating film 22 is provided with a protective layer 23 mainly composed of silicon.
[0022]
The effect | action is demonstrated below about the above structure.
[0023]
A thermal diffusing agent (for example, silicon) of the sensor 21 attached to the body and pressed against the top plate 12 is interposed between the top plate 12 and the sensor 21. Usually, the thermal diffusing agent penetrates into the printed film and the blur is visible from the outside, but the surface layer of the chromatic color coating film 22 is covered with the protective layer 23 mainly composed of silicon, so that the blur is suppressed. It does not appear on the appearance of the top plate 12. Further, the silicon protective layer 23 can remarkably improve the coating strength of the chromatic color coating film 22 and can eliminate the appearance defect due to scratches during assembly work and service.
[0024]
As described above, in this embodiment, even when the chromatic color coating film 22 is provided on the lower surface of the top plate 12 by the silicon protective layer 23, the appearance quality is not impaired, and the quality can be further improved.
[0025]
(Example 2)
The coating-film structure in the top plate of the heating cooker in Example 2 of this invention is demonstrated. The description will focus on the differences from the first embodiment.
[0026]
The difference between this embodiment and the first embodiment is that the chromatic coating 22 is composed of a chromatic base layer 22a and a black film layer 22b, as shown in FIG. When characters or circles are printed on the top surface of the top plate 12 as in the prior art, the shadow appears on the chromatic coating film 22 on the bottom surface of the top plate 12 (thickness of about 4 mm), and the visibility is significantly reduced. However, according to this configuration, it is possible to display the characters and the circular printed portion on the black film layer 22b by removing the chromatic base layer 22a, so that the visibility can be remarkably improved.
[0027]
(Example 3)
The coating-film structure in the top plate of the heating cooker in Example 3 of this invention is demonstrated. The description will focus on the differences from the second embodiment.
[0028]
As shown in FIG. 3, the present embodiment is different from the second embodiment in that the light emitting means 20 provided below the top plate 12 corresponding to the heating unit 15 is provided and the bottom surface of the top plate 12 facing the light emitting means 20. At least a part of the structure has a translucent portion 24 in which the black film layer 22b is not provided. Generally, the black film layer 22b is non-translucent or semi-translucent, and it is difficult for the light emitted from the light emitting means 20 to pass through. However, if only the chromatic ground layer 22a is used, the translucency is improved. According to the configuration, it is possible to further improve the translucency of the light emitting means 20 and greatly improve the visibility.
[0029]
Example 4
The coating-film structure in the top plate of the heating cooker in Example 4 of this invention is demonstrated. The description will focus on the differences from the third embodiment.
[0030]
The difference between the present embodiment and the third embodiment is that a light transmitting portion 24 is provided in a spot shape as shown in FIG. When except for the black film layer 22b is provided a light transmitting portion 24, not only the part and hue exists black film layer 22 b is significantly different, a transparent portion 24 excluding the black film layer 22 b, the inner body challenge of the built-in parts are visible results. However, according to this configuration, it without the translucent portion 24 is visible almost from the appearance, it is possible to prevent that the built parts visible.
[0031]
( Reference Example 1 )
The coating-film structure in the top plate of the heating cooker in the reference example 1 of this invention is demonstrated. The description will focus on the differences from the second embodiment.
[0032]
This reference example is different from the second embodiment in that the spotted non-coating portion 25 is provided on the chromatic base layer 22a as shown in FIG. When the chromatic coating film portion 22 is formed with a large area, skimming in screen printing occurs and a large problem arises in mass productivity. In addition, when spot-like printing is performed on the top surface of the top plate 12 as in the past in order to hide the unevenness (make it difficult to see), the chromatic coating film 22 on the bottom surface of the top plate 12 (thickness of about 4 mm) becomes a shadow. And the visibility will be significantly reduced. However, according to this configuration, it is possible to significantly improve unevenness by providing a spot-like print portion on the lower surface of the top plate 12, and the black film layer can be obtained by removing the spot-like print by removing the chromatic base layer 22a. Since it can display with 22b, visibility can be improved significantly and an external appearance quality can further be improved.
[0033]
( Reference Example 2 )
The coating-film structure in the top plate of the heating cooker in the reference example 2 of this invention is demonstrated. In addition, it demonstrates centering on a different point from the reference example 1. FIG.
[0034]
This reference example is different from the reference example 1 in that a translucent coating film 26 is provided on the top surface of the top plate 12 as shown in FIG. The conventional spot-like printing provided on the top surface of the top plate 12 has the effect of preventing the cooking container from slipping and preventing scratches on the glass surface of the top plate 12. When displayed on the film layer 22b and printed on the upper surface of the top plate 12 with a chromatic pigment, the printed part interferes and the appearance product is significantly lowered. However, according to this configuration, the printing provided on the upper surface of the top plate 12 is the light-transmitting coating film 25, so that no shadow is reflected on the lower surface of the top plate 12, and the cooking container is prevented from slipping. Can also prevent the top plate 12 from being damaged.
[0035]
【The invention's effect】
As described above, according to the present invention, the thermal diffusing agent (for example, silicon) of the sensor that is attached to the main body and pressed against the top plate does not bleed and does not appear on the appearance of the top plate. Furthermore, the protective layer of silicon significantly improves the coating strength of chromatic color printing, so that it is not damaged during assembly work or service.
[0036]
In addition, the translucent part is hardly seen from the appearance, and the built-in parts can be prevented from being seen.
