Description

  The present invention relates to an electronic device and a heating cooker used for general household use and business use.

Conventionally, this type of electronic device and cooking device such as an induction cooking device improve the operability of cooking by providing a capacitance detection type touch key on the top plate corresponding to the upper surface of the device. If the touch key is pressed continuously for a certain period of time, such as when a pan is placed on the key or the water in the pan is spilled, an abnormality is detected and heating is stopped, and acceptance of the touch key is prohibited. Some devices are designed to be safe (see, for example, Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a plan view of a heating cooker which is an example of an electronic device according to the first embodiment of the present invention, FIG. 2 is an enlarged plan view of an operation unit in the heating cooker, and FIG. 3 is a block in the heating cooker. FIG.

  In FIG. 1, the heating cooker 1 has a heating means 3 for induction heating of a pan, and a heating coil (not shown) constituting an induction heating means corresponding to the heating means 3 is provided inside the heating cooker 1. And an energization control circuit (not shown) which is a power supply circuit of the heating coil is arranged below the heating coil. And it has the top plate 2 which made the crystallized glass the raw material which can be installed in the upper part of the heating means 3 and can install a pan. The top plate 2 is surrounded by a plate frame 5 so as to be covered. In addition, a plurality of operation units 4 a to 4 f for inputting conditions for performing heating cooking provided on the same surface as the top plate 2 are provided. In detail, as shown in FIG. 2, in addition to a heating on / off key 4a for energizing the heating means 3, a heating power up key 4b and a heating power down key 4c for adjusting the heating power of the heating means 3 are arranged. A frying key 4d, an auto cooking key 4e, a cancel key 4f, and the like are arranged, and each operation unit is provided with a light emitting means.

  Furthermore, as shown in FIG. 3, when the cooking device 1 is input to one of the plurality of operation units 4, the next input operation unit that is likely to be input next is specified. Storage unit 7 storing next input operation unit information, an abnormality detection unit 8 that detects that the operation unit is in an abnormal state, and an operation unit other than the one operation unit and the next input operation unit. A determination unit 6 that determines that there is an abnormality when the abnormality detection unit detects an abnormality in one operation unit and the next input operation unit. Yes.

  The operation and action of the cooking device configured as described above will be described below with reference to FIGS.

  First, cooking is started when the heating means 3 heats after operating the heating on / off key 4a of the operation unit 4. At this time, the determination unit 6 identifies the thermal power up key 4b and the thermal power down key 4c as the next input operation unit that is likely to be input next, based on the next input operation unit information stored in the storage unit 7. . At this time, the current operation status is notified by turning on the heating on / off key 4a which is also the one operation unit, and the user is allowed to perform the next operation by blinking the heating power up key 4b and the heating power down key 4c. It is possible to prompt the user to understand the operation procedure of the device at a glance. In addition, when an inadvertent key is pressed during cooking (for example, a state where the key is continuously pressed for a certain period of time or a state where multiple keys are pressed in a plurality of operation units), the pressed key is a heating on / off key. In the case of 4a, thermal power up key 4b and thermal power down key 4c, it is determined that an abnormality has occurred and the operation of the device is invalidated. When an abnormality is detected, it is determined that there is no abnormality and the operation of the device can be continuously used so that the cooking operation is not easily stopped, so that the usability can be improved.

  On the other hand, when the automatic cooking key 4e of the operation unit 4 is operated, the determination unit 6 is based on the next input operation unit information stored in the storage unit 7 and is likely to be input next, the next input operation unit, thermal power The up key 4b and the thermal power down key 4c are specified. At this time, the automatic cooking key 4e, which is also one of the operation units, is turned on to notify the current operation status, and the user can be made to blink the heating power up key 4b, the heating power down key 4c, and the heating on / off key 4a The following operations can be promoted to allow the user to understand the operation procedure of the device at a glance. Also, when an inadvertent key is pressed during cooking, if the pressed key is the heating on / off key 4a, the thermal power up key 4b, or the thermal power down key 4c, it is determined that an abnormality has occurred and the operation of the device is performed. If an abnormality is detected in the operation section other than the heating on / off key 4a, the heating power up key 4b, and the heating power down key 4c, it is determined that there is no abnormality and the operation of the equipment can be continued and used. Usability can be improved by adopting a configuration in which the operation is not easily stopped.

  In addition, the judgment part 6 is when the abnormality detection part 8 detects abnormality in operation parts other than the heating on / off key 4a which is one operation part, and the thermal power up key 4b and the thermal power down key 4c which are next input operation parts. Is determined as abnormal, and when the abnormality detection unit 8 detects an abnormality in the one operation unit heating on / off key 4a, the next input operation unit heating power up key 4b, and the heating power down key 4c, it is determined to be abnormal. However, the present invention is not limited to this, and when the abnormality detection unit 8 detects an abnormality in the operation unit other than the thermal power up key 4b and the thermal power down key 4c as the next input operation unit, it is determined that there is no abnormality, A configuration may be adopted in which when the abnormality detection unit detects an abnormality in the thermal power up key 4b and the thermal power down key 4c, which are the next input operation unit, it is determined that there is an abnormality.

  Further, although the heating on / off key 4a as one operation unit and the heating up key 4b and the heating down key 4c as next input operation units are separate operation units, a single operation unit should have a plurality of functions. (In this embodiment, the heating on / off key 4a has a function of inputting heating and a function of turning off heating), and the first operation unit and the next input operation unit may overlap.

  In addition, although demonstrated using the heating cooker in this Embodiment, it is not limited to this, The same effect can be acquired also in a washing machine, an air-conditioner, and another electronic device.

  As described above, in the present embodiment, when the abnormality detection unit detects an abnormality in the operation unit other than the one operation unit and the next input operation unit, it is determined that there is no abnormality, and the abnormality detection unit has one When an abnormality is detected in the operation unit and the next input operation unit, it is determined that there is an abnormality, so that safety and usability can be effectively improved even if a key abnormality occurs.

  As described above, since the electronic device and the heating cooker according to the present invention can effectively improve the usability for the user, various electronic devices, induction heating cookers, electric heating cookers, etc. Applicable.
