Description

Description: TECHNICAL FIELD The present invention relates to a heater wiring structure for a cooking appliance.

2. Description of the Related Art In a conventional cooker shown in FIG. 3, for example, a lead wire 3 connected to a heater 2 is connected to a heater cover 4 which is heated to a high temperature, a metal end face 5 having burrs, and a louver 13 for ventilation. It was fixed with a wire holder 6, a plug-in fixed binding band 7, or the like.

SUMMARY OF THE INVENTION However, in the configuration of this cooking device, the cost of parts is high because there are many fixing points of the lead wire, the operation is performed within a narrow predetermined interval, and the operation is difficult. And the number of manufacturing steps is increased. An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a cooker that has a simple structure, has good workability, and can sufficiently secure safety.

Means for Solving the Problems In order to achieve the above object, a cooking device of the present invention comprises a main body case, a heating chamber provided at predetermined intervals in the main body case, a heater for heating food in the heating chamber, and a heater. Lead wire wired to the wire, an insulator provided through the lead wire immediately after the heater connection terminal of the lead wire, and a wire-shaped support formed by bending along the flow of the lead wire immediately after the insulator, and this wire-shaped support. The lead wire and the wire-like support are connected together at a plurality of places, and are held together by being inserted into gaps formed on both sides of the cut-down portion provided near the foot of the support.

Action The cooking device of the present invention is bound with a tape or the like to an ideally bent wire-like support without complicated fixing so that the lead wire does not touch a metal end surface having a burr or a high-temperature portion. This has the effect of not touching a metal end face or a high-temperature portion having a problem.

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, reference numeral 8 denotes a 2 m diameter bent to the ideal shape of the lead wire 3 connected to the terminal of the heater 2.
The support is made of a metal rod having a length of about m, and its feet are formed at both ends of a cut-out portion 10 where two cuts are made in a part of the heater cover 4 on the bottom surface 9 of the heating chamber and the cuts are narrowed. It is inserted in the gap. The necessary number of the support members 8 are bound together with the lead wires 3 with a tape 11 or the like, and the center of the support member 8 is held by the lead wire holder 6. A terminal for connection of the lead wire 3 is fastened to a terminal of the heater 2 with a screw, and an insulator 12 is passed between the terminal for connection and the support 8 until it is bound to the terminal.
As shown in FIG. 2, the lead wire 3 is a high temperature portion, a heater cover 4, a metal end face 5 having burrs, and a louver for ventilation.
I try not to hit 13. With such a configuration, the fixing tool is not required because the foot of the support member 8 is cut and inserted into the gaps formed at both ends of the narrowed portion 10, and a hole is not formed in the bottom of the heating chamber, so that assembling is facilitated. In addition, the variation in length from the connection terminal of the lead wire to the binding position with the support 8 due to the co-rotation generated when the connection terminal of the lead wire 3 is fastened to the terminal of the heater 2 with a screw can be absorbed. No unnecessary stress is applied to the substrate.

Effects of the Invention As described above, according to the cooking device of the present invention, the following effects can be obtained.

(1) The use of the wire-like support does not require a large number of lead wire holders and eliminates the need to wrap a tape or the like around the lead wire for measures against edges, thereby reducing material costs.

(2) By providing a movable range for the legs of the wire-shaped support, fixing screws are not required, and the support is connected from the lead wire connection part by co-rotation when the lead connection terminal is screwed to the heater terminal. It can absorb variations in length up to and without applying unnecessary stress to the lead wires.

(3) Inserting and fixing the wire-shaped support unit that is plugged in and connected to the lead wire eliminates the need to insert a hand at a narrow interval to fix the holder, thus increasing the work safety and improving the workability. Is greatly reduced and economical.
