[Prior Art]

 In the conventional high-frequency heating cooker, a heating chamber 22 is provided in the cooker body 21, and a tray 24 on which food 23 is placed on the bottom of the heating chamber 22 and a roller stay 25 on which the tray 24 is rotated to rotate. There was a turntable. Further, a door 26 is provided on the front surface of the cooker main body 21 to open and close an opening for taking food in and out of the heating chamber 22, and an operation panel 27 is provided adjacent to the door 26.

The heating chamber 22 is formed of a steel plate, and a drive motor 28 that rotationally drives the roller stay 25 of the turntable is arranged outside the bottom of the heating chamber 22. The drive motor 28 was screwed to a mounting angle 29 formed of a steel plate with a screw 30, and the mounting angle 29 was fixed to the outside of the bottom of the heating chamber 22 by spot welding.

A through hole through which the rotary shaft 31 of the drive motor 28 penetrates is provided at the bottom of the heating chamber 22, and the rotary shaft 31 is connected to the coupling provided on the roller stay 25.

A coupling 32 is formed around a rotation shaft 31 of the drive motor 28, and a ring-shaped packing 33 is interposed between the coupling 32 and the mounting angle 29 to electrically connect the drive motor 28. The water was prevented from entering the section.

[0006]

[Problems to be solved by the device]

 In the case of the high-frequency cooker having the above-described configuration, the material of the mounting angle 29 and the heating chamber 22 needs to be formed by a material capable of spot welding, so that the material of the mounting angle 29 and the heating chamber 22 is restricted and the productivity is high. In addition, since the coating cannot be improved and the coating applied to the stains to the heating chamber 22 is less likely to adhere and the coating for self-cleaning is restricted, measures against the stains in the heating chamber 22 can be improved. It was difficult.

The high-frequency heating cooker of the present invention has been made in view of the above problems, and the periphery of the through hole at the bottom of the heating chamber is extended to form an angle mounting portion, and the angle mounting portion is formed. The purpose is to allow the mounting angle to be fixed to the heating chamber by crimping the part and the mounting angle.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the high-frequency heating cooker of the present invention forms a heating chamber with a steel plate, and rotatably arranges a turntable on which a food is placed and rotated at the bottom of the heating chamber. A drive motor for rotationally driving the turntable is disposed outside the bottom of the heating chamber by a mounting angle, and a through hole through which the rotation shaft of the drive motor penetrates is formed in the bottom of the heating chamber. In a high-frequency cooker in which a shaft and the turntable are connected, the heating chamber is formed of a PCS steel plate with heat-resistant insulating resin on both sides of a steel plate, and the mounting angle is formed of a PCS steel plate. The periphery of the through hole at the bottom of the heating chamber is extended outward to form an angle mounting portion, a projection is formed on either the angle mounting portion or the mounting angle, and the projection is formed on either side. Shape the hole to insert Then, a protrusion is inserted into the hole and the angle mounting portion and the mounting angle are crimped to separate the heat resistant insulating resin from the protruding portion to ground the angle mounting portion and the mounting angle.

Further, a packing is airtightly fitted around the periphery of the through hole at the bottom of the heating chamber.

[0010]

[Action]

 In the high-frequency cooker having the above-mentioned configuration, the heating chamber and the mounting angle are formed by the PCS steel plate, and the projection provided on either the angle mounting portion or the mounting angle is inserted into the hole provided on the other side. By caulking the angle mounting portion and the mounting angle, the heat resistant insulating resin on the protrusion is peeled off and the angle mounting portion and the mounting angle are grounded.

[0011]

【Example】

 An embodiment of the high-frequency heating cooker of the present invention will be described with reference to the drawings. The high frequency heating cooker of the present invention is provided with a heating chamber 1 in the cooker body, and a tray 3 on which the food 2 is placed and a roller stay 4 on which the tray 3 is placed and rotated at the bottom of the heating chamber 1. There is a turntable The heating chamber 1 is formed by a PCS steel plate 7 in which an epoxy polyester 6 (20 μm) which is a heat resistant insulating resin is applied to both sides of the steel plate 5, and the turntable is provided outside the bottom of the heating chamber 1. A drive motor 8 for rotating the roller stay 4 is provided.

The drive motor 8 is screwed to a mounting angle 9 formed of a PCS steel plate with screws 10, and the mounting angle 7 is fixed to the outside of the bottom of the heating chamber 1 by caulking. A through hole through which the rotary shaft 11 of the drive motor 8 penetrates is provided in the bottom of the heating chamber 1, and the rotary shaft 11 is connected to the coupling provided in the roller stay 4.

A peripheral edge of a through hole at the bottom of the heating chamber 1 is extended to form an angle mounting portion 12, a hole 13 is formed in the angle mounting portion 12, and a protrusion 14 is formed in the mounting angle 7. Then, the projection 14 of the mounting angle 7 is inserted into the hole 13 of the angle mounting portion 12, and the angle mounting portion 12 and the mounting angle 7 are fixed by caulking. At this time, the epoxy polyester 6 of the PCS steel plate of the protrusion 14 of the mounting angle 7 is peeled off, and the steel plate 5 of the mounting angle 7 and the steel plate 5 of the angle mounting portion 12 are electrically connected and grounded.

A packing 15 is airtightly fitted to the bottom of the heating chamber 1 in a through hole so that water or the like from the inside of the heating chamber 1 does not enter the drive motor 8.

[0015]

[Effect of the device]

 Since the high-frequency cooker of the present invention has the above-mentioned configuration, the drive motor mounting angle can be fixed to the heating chamber by caulking instead of spot welding, and there are no restrictions on measures against dirt in the heating chamber. It can be improved without receiving it, and the mounting angle and the heating chamber can be grounded at the same time when caulking is performed, and the structure is very simple.

Further, only by fitting the coupling into the through hole of the heating chamber, it is possible to reliably prevent water from entering the drive motor.
