  The electric cooking machine of the present invention does not require a mechanical detection member to be disposed on the container base, has an interlock function with a simple structure, and is excellent in cleanability.

  A first invention includes a main body having a built-in electric motor, a container base having a cutter detachably mounted on the main body and driven to rotate by the electric motor, and a container detachably attached to the container base. A lid that covers the upper opening of the container, an interlock device that interlocks the electric motor, and an RFID antenna, wherein an RFID is provided on at least one of the container base, the container, and the lid, When the RFID is detected, the interlock device releases the interlock of the electric motor, and an electric cooker having an interlock function with a simple structure and good cleanability can be obtained.

  In the second invention, in particular, an RFID is provided on each of the container base, the container, and the lid of the first invention, and when the RFID antenna detects all of the RFID, the interlock of the electric motor is released. Thus, the interlock structure can be simplified in the same manner as in the first invention, and the interlock can be released only when the detachable container base, container, and lid are assembled.

  In the third invention, in particular, all the RFIDs provided on the container base, the container, and the lid of the second invention are detected by one RFID antenna. Can be simple.

  In the fourth invention, in particular, the RFID antenna according to any one of the first to third inventions has a high directivity to narrow the azimuth range in which RFID can be detected. Alternatively, the RFID can be detected only when the RFIDs provided in all exist in a predetermined correct orientation.

  In the fifth invention, in particular, the RFID antenna according to any one of the first to fourth inventions measures the intensity of the reflected reflected wave from the RFID, and the intensity of the received reflected wave is within a predetermined upper limit value and lower limit value range. The interlock of the electric motor is released only when it is inside, and the RFID is detected only when the RFID provided on any or all of the container base, container, and lid exists at a predetermined correct distance. To be able to do so.

  In the sixth invention, in particular, when a plurality of highly directional RFID antennas having a narrow detectable azimuth range of the RFID of the first invention are arranged, and all of the RFID antennas detect RFID simultaneously, the interlock of the motor When an RFID is installed and any of the container base, container, and lid is correctly assembled, the position where the RFID is placed is aligned with the area where the RFID detectable range of each RFID antenna intersects If the RFID is in a predetermined correct position, that is, when the RFID is provided and the container base, container, or lid is correctly assembled, the interlock is released. it can.

  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)
1 is a longitudinal sectional view of an electric cooking machine according to Embodiment 1 of the present invention.

  In FIG. 1, reference numeral 1 denotes a main body of the electric cooking machine according to the present embodiment, which incorporates an electric motor 3 having a drive connector 2 at the top. A container base 5 having a cutter 4 is detachably mounted on the main body 1. A driven connector 6 that engages with the drive connector 2 is provided below the cutter 4, and the cutter 4 is driven to rotate by driving the electric motor 3.

  A container 7 is detachably attached to the container base 5, and a lid 8 is detachably attached to the upper opening 7 a of the container 7. In addition, the electric motor 3 is interlocked by an interlock device 10 connected in series with the operation switch 9 in the power supply circuit 25, and the interlock device 10 is highly directional with a narrow azimuth range that can be detected by RFID. In response to the signal from the active RFID antenna 11, the interlock operation and release, that is, the power supply circuit 25 connected to the motor 3 is turned off and on.

On the other hand, as shown in FIG. 1, the container base RFID 12, the container RFID 13, and the lid RFID 14 are located at positions of the container base 5, the container 7, and the lid 8 that correspond to the detectable azimuth range of the RFID antenna 11. The RFID antenna 11 measures the intensity of the reflected wave received from each of the container base RFID 12, the container RFID 13, and the lid RFID 14, and the intensity level of the reflected waves of all RFIDs is determined by the container base 5. Only when the container 7 and the lid 8 are within the range between the upper limit value and the lower limit value so as to cover the range corresponding to the distance to each RFID when the container 7 and the lid 8 are correctly assembled, It is intended to be released.

  As described above, according to the present embodiment, the container base 5, the container 7, and the lid 8 are correctly assembled, and only when the container base RFID 12, the container RFID 13, and the lid RFID 14 are in a predetermined direction and distance, that is, The interlock is released only after the container base 5, the container 7 and the lid 8 are correctly assembled and the container base 5 is placed at a predetermined position of the main body 1.

(Embodiment 2)
FIG. 2 is a longitudinal sectional view of the electric cooking machine according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to the same part as the electric cooker in the said 1st Embodiment, and the description is abbreviate | omitted.

  In FIG. 2, the electric cooking machine according to the present embodiment includes a container base 20 that is mounted on the main body 1 and has a cutter 4 that is rotatable, a container 21 that is detachably attached to the container base 20, and a container 21, a lid 17 in which a lid RFID 18 is embedded, and a high-directivity first RFID antenna 15 and a second RFID antenna 16 each having a narrow azimuth range that can be detected by the RFID. When the container base 20, the container 21 and the lid 17 are correctly assembled at the intersection of the azimuth detection ranges of the RFIDs of the first RFID antenna 15 and the second RFID antenna 16, the lid 17 It is made to coincide with the position where the lid RFID 18 comes.

  Further, the electric motor 3 is interlocked by an interlock device 19 connected in series with the operation switch 9, and both the first RFID antenna 15 and the second RFID antenna 16 are covered simultaneously. The interlock is released only when the RFID 18 is detected.

  Since the electric cooking machine in the present embodiment is configured as described above, only when the container base 20, the container 21 and the lid 17 are correctly assembled and the lid RFID 18 of the lid 17 is in a proper position. The interlock can be released. In particular, in the present embodiment, since there is no need to embed RFID in cooking container parts such as the container 21 and the container base 20 below the lid 17, an electric cooking machine can be configured at low cost.
