Description

  The present invention relates to an induction heating cooker used in general households.

  Conventionally, this type of cooking device has an automatic cooking menu, and the user selects and operates it, for example, fried food cooking at a constant temperature and cooking rice cooking The function that can be done is now installed. Such a function is very convenient because the user can perform cooking without any failure at any time with a simple operation.

  However, in such a configuration, when cooking, the user needs to examine the recipe with a cooking book, for example, and adjust the heating and watching the cooking book or select an automatic cooking course. For this reason, it can be said that there is room for examination whether operation and cooking can be performed more easily. Here, in order to simplify the operation, it is conceivable to perform communication between the cooker body and the outside.

  Here, as an example of communication in a cooking device, for example, in Cited Document 1, a container having an IC tag built in a handle portion is used, and a heating coil for induction heating the container and the container placed on the heating coil are placed. The top plate is printed with a size larger than the outer shape of the heating coil and communicates with the container.

JP 2007-134257 A

  However, the configuration of Cited Document 1 requires a container with an IC tag built into the handle portion, and there is a problem that communication is not possible with containers that are generally sold. In addition, information such as various cooking recipes cannot be obtained by simply communicating with a container.

  For this reason, it is conceivable that automatic connection or the like is performed even in containers that are generally sold by connecting to the Internet with a portable terminal or the like and communicating information arbitrarily obtained from the information with an induction heating cooker. In addition, an RFID (Radio Frequency IDentification) tag may be provided for the communication so that the induction heating cooker reads data by bringing the portable terminal closer.

  However, it is considered that the position of the portable terminal close to the top plate of the heating coil is preferable for the user because the position is easy to see, but it is very hot during cooking or immediately after cooking. May affect safety.

  Moreover, when trying to communicate with a portable terminal by RFID during cooking, it is considered that communication cannot be performed due to noise caused by the heating coil, and there is a risk of failure of the portable terminal itself due to induction heating.

  The present invention solves such a problem, and improves the convenience of the user by taking in information from the outside using communication via a portable terminal, and enables safe and reliable communication. An object is to provide an induction heating cooker.

  In order to achieve the above object, the present invention includes a main body having an induction heating coil unit and an RFID tag that performs proximity communication, and the RFID tag is disposed below the ferrite core of the induction heating coil unit. It is as.

  As a result, noise generated from the induction heating coil unit does not easily reach the lower side due to the ferrite core, and when the portable terminal is brought close to the RFID tag, it is less likely to cause a communication failure due to noise. There is no risk of failure.

  As described above, according to the present invention, since communication is performed using an RFID tag, there is no security problem, and data can be transmitted and received safely and reliably without malfunction during communication and failure of the mobile terminal. I can do it.

The perspective view of the induction heating cooking appliance in Embodiment 1 of this invention Sectional view of FIG. 1 viewed from the direction A The front view of the induction heating cooking appliance in Embodiment 1 of this invention The figure which shows the other example of attachment of the RFID tag 6 in Embodiment 1 of this invention.

  Further, the grill door 9b of the grill device 9 is provided with a grill caution display section 13 indicating that the grill door 9b is hot. The operation unit front panel 11a is provided with a grill heating display unit 14 that alerts the user that the grill device 9 is in use or the door is hot.

  FIG. 4 shows an example in which the RFID tag 6 is separately arranged at a position.

  About the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The user connects the mobile terminal to the Internet and obtains recipe information such as a cooking menu, cooking method, and device setting conditions. And the data, such as setting conditions of equipment, such as 15 minutes with thermal power 2 and then 20 minutes with thermal power 1, are transmitted to the induction heating cooker. At that time, the portable terminal is set in a transmission state, and data is transmitted by bringing it close to the RFID tag 6 of the induction heating cooker. Specifically, communication is performed by holding the portable terminal in contact with or close to the RFID tag display unit 6a of the operation unit front panel 11a.

  After sending the data, the operating conditions of the device are already entered, so the user simply operates the heating start key and starts automatic cooking under the operating conditions that match the selected dish. can do.

  At this time, communication may be hindered by noise emitted from the induction heating coil 3a, such as when another container is already heated by another induction heating unit. In the present embodiment, the RFID tag 6 is arranged on the lower surface side of the ferrite core 3b attached to the induction heating coil unit 3 in order to make it less susceptible to noise.

  Here, the ferrite core 3b of the induction heating coil unit 3 is provided in order to concentrate the magnetic flux on the upper surface side of the induction heating coil 3a to improve efficiency and improve the heating distribution of the object to be heated. Therefore, by arranging the RFID tag 6 on the lower surface side of the ferrite core 3b attached to the induction heating coil unit 3, it is possible to make it less susceptible to magnetic flux below the ferrite core 3b. That is, the influence of noise emitted from the induction heating coil 3a can be prevented.

  Further, the RFID tag 6 is easily affected by metal parts, and if there is a metal part nearby, communication is likely to fail. For this reason, it is arranged near the center of the main body height and at a position away from the main body case 1. Thereby, the influence by the main body case 1 can be suppressed. Furthermore, since the RFID tag 6 is disposed near the center of the induction heating cooker provided in the kitchen, the portable terminal can be brought closer without being affected by the installed state.

  Also, in the left-right direction, the influence from the side surface of the main body case 1 can be reduced by disposing it at a position away from the side surface of the main body case 1 by a predetermined distance. Furthermore, even if there is a kitchen wall on the left or right side of the induction heating cooker, the user can operate the portable terminal 15 without getting in the way. In the present embodiment, the RFID tag display unit 6a is arranged at a position away from the grill door 9b by a predetermined distance in the vicinity of the grill door 9b. The predetermined distance may be a distance that does not accidentally touch the grill door 9b when the user tries to bring the mobile terminal 15 closer. For example, about 3 cm in consideration of the width of a general mobile terminal It only has to be away.

  Further, the RFID tag 6 is not fixed with a metal screw or the like, and is fixed to the main body case only with resin parts. That is, the RFID tag 6 is set in a synthetic resin holder 6b. Further, the holder 6b is attached to the case of the resin operation portion 10 by a claw provided on the holder 6b. For this reason, the influence of noise and metal parts that hinders communication is suppressed as much as possible, and the communication state is optimized, so that the RFID tag 6 can be suppressed to the minimum necessary size, and space-saving and inexpensive. Can be configured.

  Further, a grill attention display unit 13 or a grill heating display unit 14 is provided in the vicinity of the RFID tag display unit 6a. For this reason, when the user holds the portable terminal 15 over or in contact with the RFID tag display unit 6a, the user can be prevented from touching the hot grill door 9b by mistake or be alerted.

  The display area of the RFID tag display unit 6 a is smaller than the actual RFID tag 6 and is disposed within a range corresponding to the RFID tag 6. As a result, when the user brings the mobile terminal 15 closer, even if the position is slightly shifted, it is included in the communication sensitivity of the RFID tag 6, and communication can be performed reliably. As shown in FIG. 4, the position of the RFID tag 6 may be configured to be able to communicate with the portable terminal 15 with the retractable operation unit 10 in the extended state. In this case, the RFID tag 6 may be disposed substantially in parallel with the operation surface below the operation surface of the operation unit 10. As a result, communication can be reliably performed. Furthermore, since the operation surface of the operation unit 10 is in a position that can be easily seen by the user during cooking, the portable terminal can be brought closer to the RFID tag display unit 6a smoothly. Furthermore, since the retractable operation unit 10 protrudes outward from the main body case 1, it is further away from the induction heating coil 3a, and as a result, is less susceptible to noise during communication.

  As for the communication method, other short-distance wireless communication may be used as long as it can be discriminated by limiting the target by touching or holding the product.

  In the present embodiment, the built-in induction heating cooker has been described, but it goes without saying that the present invention can be similarly applied to a stationary type or other induction heating cooker.

  As described above, according to the present invention, there is provided an induction heating cooker that has a simple configuration, is highly reliable, can reliably communicate with a mobile terminal, and does not cause a failure of the user's mobile terminal. I can do it.
