(Prior art) This type of heating cooking device that has already been proposed is
It is constructed as shown in FIGS. 3 to 5.

That is, in FIGS. 3 to 5, an oven 2 is formed in an oven frame 1 in a box-shaped case body (cabinet), and an opening 1a of the oven frame 1 has an oven 2 formed therein. , an opening/closing door (not shown) is provided so as to be openable and closable. Further, an operation panel 3 equipped with a timer and operation buttons is attached to the front opening of the case body, and a rectangular plane heater 4 is attached to the top plate 1a of the oven frame 1. On this plane heater 4, a flat heat insulating material 5 and a heat shield plate 6 are provided in an overlapping manner. Furthermore, the planar heater 4 includes:
As shown in an enlarged view in FIG. 4, each terminal 9 is provided through which the insulator body 7 and each insulator tube 8 are passed, and each terminal 9 extends to the vicinity of the side plate 1b of the oven frame 1. It has been extended. Furthermore, a mounting plate (lock mounting plate) 10 that also serves as a heat shield is attached to the side plate 1b of the oven frame 1.
A cutout window 10a is bored in the upper part of the mounting plate 10. Further, each of the insulator tubes 8 and each of the terminals 9 are passed through the cutout window 10a, and the mounting plate 10 on which each of the terminals 9 is located has an insulating plate on which a pair of terminal rods 11 are embedded. 12 is fixed horizontally with a set screw 13. Further, each terminal 9 is screwed and connected to each terminal rod 11 with each nut 13, and the end of each insulator tube 8 is tied to the mounting plate 10 with each mounting band 14. has been done.

Therefore, in the heating cooking device described above, a shelf board on which the food to be cooked is placed is inserted into the oven 2 in advance, and then the plane heater 4 is energized, so that the plane heater 4 is heated in the oven. The food to be cooked in No. 2 is heated and cooked.

(Problems to be Solved by the Invention) However, the heater mounting device of the heating cooking device described above, as shown in an enlarged view in FIG.
Each terminal (round terminal) 9 is caulked and attached to the lead wire of the flat heater 4.
are connected to each terminal rod 11 of the insulating plate 12 horizontally mounted on the outside of the mounting plate 10, not only does the length of the lead wire of the planar heater 4 become long, but also the length of the lead wire of the insulator increases. There is also a risk that the tube 8 will be economically misaligned and the electrical insulation will be impaired.
Furthermore, since the insulating plate 12 is provided horizontally, the space in the machine room formed within the case body is restricted, which obstructs the assembly of various electrical components, and also prevents the cooling fluid of the magnetron from being used, for example. There is also a risk of interference.

In order to solve the above-mentioned difficulties, the present invention fixes the plate in close vertical contact with the mounting plate where the notch is located, shortens the length of the lead wire of the flat heater, and forms the lead wire inside the case body. The machine room is designed to be large so that it does not interfere with the assembly of various electrical parts, improving workability during assembly, saving labor through mass production, and improving the above-mentioned performance and safety. It is an object of the present invention to provide a heating cooking device that achieves the following objectives.

[Summary of the idea]

(Means for solving the problems and their effects) In the present invention, a plane heater is attached to the top plate of the oven frame forming the oven, and each terminal through which each insulator tube is passed is attached to the plane heater. In the heating cooking device, a mounting plate is attached to one side of the oven frame, a notch is formed in the mounting plate, and an insulating plate is vertically and closely attached to the mounting plate where the notch is located and fixed. The above terminals are connected to each terminal rod of this insulating plate to shorten the length of the lead wires of the above flat heater, and to avoid getting in the way of assembling various electrical parts, improving work efficiency during assembly. It is designed to improve insulation and safety.

(Example) Hereinafter, the present invention will be described with reference to an illustrated example.

It should be noted that the present invention will be described with the same reference numerals attached to the same constituent members as in the above-described specific example.

In FIGS. 1 to 3, reference numeral 1 denotes an oven frame provided in a box-shaped case body, and an oven 2 is formed in this oven frame 1. An opening/closing door (not shown) is provided in the opening 1a of the oven frame 1 so as to be openable and closable. Further, an operation panel 3 equipped with a timer and operation buttons is attached to the front opening of the case body, and the top plate 1a of the oven frame 1
A rectangular plane heater 4 is attached thereto, and a flat heat insulating material 5 and a heat shield plate 6 are superimposed on the plane heater 4. moreover,
As shown in an enlarged view in FIG. 1, the planar heater 4 is provided with terminals 9 that extend through the insulator body 7 and each insulator tube 8, and each terminal 9 is connected to the oven frame. It extends to the vicinity of the side plate 1b of the body 1. Furthermore, the side plate 1b of the oven frame 1 is provided with a mounting plate (lock mounting plate) that also serves as a heat shield.
10 is attached, and a notch 10b is formed in the upper part of this mounting plate 10. Further, each of the insulator tubes 8 and each of the terminals 9 are passed through the notch 10b, and the mounting plate 10 on which each of the terminals 9 is located has an insulating plate on which a pair of terminal rods 15 are embedded. 16 are fixed vertically in close contact.

That is, this insulating plate 16 is formed with a substantially inverted W-shaped cutout groove 16a, and one end of each of the insulator tubes 8 through which each of the terminals 9 is passed is extended into the cutout groove 16a. There is. Further, both lower end portions 16b of the insulating plate 16 are connected to each cut-and-raised piece 1 of the mounting plate 10.
0c is inserted through the insulating plate 16.
A part of each locking piece 1 formed on the mounting plate 10
0d, each of the terminal rods 15
