[0012]
Hereinafter, in the embodiments of the present invention, a case where operation keys are used as operation means will be described. On the surface of the top plate 12, there is provided an operation unit 18 having operation keys as operation means that are frequently used such as power supply opening / closing of the heating unit 15 and heating power adjustment. In the present embodiment, the operation unit 18 is provided with operation units 18a and 18b corresponding to the induction heating units 15a and 15b that are frequently used. Further, the operation units 18a and 18b are respectively composed of a power open / close key for the heating units 15a and 15b, and an up key and a down key for heating power adjustment.
[0013]
As shown in FIG. 2, a detection unit 19 that detects an input operation by the operation unit 18 and a control unit 20 that controls the heating unit 14 according to the input operation are provided on the lower surface of the top plate 12. The detection means 19 is comprised from the detection part 19a and the electroconductive elastic body 19b. Further, the operation unit 18 is provided on the surface of the top plate 12, that is, on the front side of the top plate 12 and at a position away from the detection unit 19 a of the detection means 19. And the printing material containing conductive metals, such as gold | metal | money and silver, etc. are used as the electroconductive material 21, and the lower surface of the operation part 18 and the detection part 19a are electrically couple | bonded by printing on the back surface of the top plate 12. FIG. Further, a conductive elastic body 19b is in pressure contact with the detection unit 19a and is electrically connected. In this way, the capacitive operation unit 18 is configured. As the conductive elastic body 19b, for example, a leaf spring as shown in the figure formed of phosphor bronze or beryllium copper, a coil spring, or a conductive rubber containing conductive particles can be used. The surface of the operation unit 18 may be printed with a conductive material. In addition, about the structure theory of an electrostatic capacitance system, description is abbreviate | omitted as a well-known technique.
[0014]
The operation and operation of the operation unit configured as described above will be described below. First, a change in capacity caused by contact operation of the operation unit 18 is detected by the conductive elastic body 19b pressure-attached by the detection unit 19a via the conductive material 21 printed on the back surface of the top plate 12, and these detection means 19 are detected. An electric signal is sent from the control means 20 to the control means 20, and the cooking container is heated by the heating means 14 corresponding to the operation.
[0015]
As described above, in this embodiment, only the frequently used operation keys are provided on the front surface of the top plate 12, so that it is possible to adjust the heating power of the heating means without changing the line of sight while cooking. The operability is greatly improved. Moreover, since there are few operation keys, the operation part 18 can be provided between the heating parts comparatively separated from the heating part 15, as shown in FIG. Therefore, the operation unit is less affected by the heat of the cooking container placed on the heating unit, and the reliability is improved.
[0016]
Furthermore, since it is provided away from the operation unit 18 in a place where there is no restriction on the height space for incorporating the detection means 19, the installation work can be facilitated without impairing operability.
Moreover, safety can be ensured without reducing the area of the heating unit 15 by securing the distance from the heating unit and providing the operation unit 18 on the surface of the top plate 12. In addition, the conductive material 21 is printed on the back surface of the top plate 12 to electrically connect the detection unit 19a located away from the lower surface of the operation unit 18, and the detection unit 19a is provided with a conductive elastic body 19b. Since the configuration is such that the operation unit 18 provided on the top plate 12 and the detection means 19 on the main body side are detachable, the assemblability is greatly improved.
[0017]
Since the front operation unit 16 has a sufficient space, all the keys necessary for the operation may be provided, or the keys provided on the operation unit 18 may be omitted.
[0018]
In the present embodiment, the induction heating portions 15 a and 15 b are provided on the front surface of the top plate 12. This is because the top plate 12 is not directly heated in the case of induction heating, in addition to being frequently used, so that the operation unit 18 can be hardly affected by heat. That is, when the method of this embodiment is used in a cooker that is heated by at least one induction heating means, the effect is great.
[0019]
In the present embodiment, a so-called three-mouthed cooking device having three heating units has been described, but it is needless to say that it is effective even in the case of a one-mouthed cooking device.
[0020]
(Example 2)
FIG. 3 is a perspective view showing a state where the cooking device according to the second embodiment of the present invention is attached to the system kitchen. It should be noted that the same functional parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. Since the basic configuration is the same as that of the first embodiment, the description will focus on the differences.
[0021]
This embodiment is different from the first embodiment in that a switching key is provided as a switching means for selecting a heating section in the operation section 18. In FIG. 3, reference numeral 22 denotes a switching key for switching the induction heating coils 14 a and 14 b provided in the operation unit 18. By operating the switching key 22, one of the induction heating coils 14a and 14b can be selected. The selected induction heating coil 14 can be easily confirmed by turning on or blinking the display means 23. In FIG. 2, the display means 23 shows a case where a point light source is used. In addition, as the display means 23, an annular display means is provided around the induction heating section, and it is confirmed that it is very easy to see if the ring of the selected induction heating section is turned on or blinking as described above. It becomes easy to do.
[0022]
In the case of the first embodiment, the operation unit 18 requires a total of six keys, that is, a power open / close key of the induction heating coils 14a and 14b and three keys each of an up key and a down key for heating power adjustment. In this case, the operation unit 18 requires only a total of four keys, that is, a switching key 22, a power switch key, a heating power adjustment up key and a down key, and there are fewer two keys than in the first embodiment. I'm sorry. Accordingly, there is a margin in the arrangement of the operation unit 18, and the heat of the heating unit 15 can be hardly affected.
[0023]
For the same reason as described in the first embodiment, when the induction heating means is used as the heating means, the effect is particularly great when two induction heating portions are provided in front of the upper surface of the top plate. Of course, it is not limited to the said Example, You may provide two or more induction heating cooking parts in a top plate.
[0024]
Further, even if the switching key is provided in the front operation unit 16, the number of keys can be reduced and the operation unit can be reduced, but the space for providing the operation unit is limited as in this embodiment. Is particularly useful.
[0025]

Therefore, all keys required for operation are provided on the top plate. In this case, if the operation unit is separated from the heating cooker unit to reduce the thermal influence of the heating cooker unit and is provided in front of the top plate, that is, on the user side, only the operation unit configuration is incorporated as described above. No space in height. Therefore, in the present embodiment, as in the case of the first embodiment, the detection unit is removed from the position facing the operation unit. The electrical connection between the operation unit and the detection unit was performed in the same manner as in Example 1. Thereby, all the keys of the operation unit can be provided apart from the heating cooker unit, and can be made less susceptible to thermal influences.
