BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control device for a cooker, and more particularly to a lead wire mounting structure.

[0002]

2. Description of the Related Art In general, a temperature control device for a cooking device has a structure in which a sliding member for temperature control is slidably supported by a guide member fixed to a cooking device body. The sliding member is provided with a rack, and the temperature adjustment rod moves up and down by rotating the pinion meshing with the rack, and the temperature adjustment rod adjusts the contact gap of the bimetal to change the set temperature. ing.

On the other hand, the power of the heating device may be switched between high and low depending on the degree of cooking. In this case, the electric power changeover switch is conventionally attached to the cooking device main body. However, it is conceivable to attach the switch to the above-mentioned sliding member for temperature adjustment. When the switch is mounted on the sliding member, the operation button of the switch can be incorporated into the operating lever of the sliding member, so that the convenience of use that the switch can be operated with the fingertip of the hand holding the lever is less convenient. is there.

[0004]

However, when the switch is mounted on a sliding member, the lead wire connected to the switch moves with the sliding of the sliding member, so that the deformation load is partially concentrated. And it is easy to cause disconnection. For this reason, it is conceivable to increase the number of core wires of the lead wires or cover the lead wires, but there is a problem that reliability is low and cost is high.

Therefore, an object of the present invention is to provide a highly reliable and low-cost lead wire mounting structure by devising a lead wire mounting structure.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a sliding member for adjusting a temperature is slidably supported by a guide member fixed to a cooking device main body. And a switch connected to the switch, and an operation button of the switch mounted on the front surface of the sliding member. In the temperature control device for a cooking appliance, a lead wire connected to the switch is locked to the sliding member. The lead wire has a sufficient space to absorb the amount of movement of the lead wire caused by sliding of the sliding member.
The guide is formed by bending the other end of the curve along a guide wall facing the sliding member, and forming a holding portion parallel to this at one end of the guide wall on the lead wire lead-out side. A gap for holding the lead wire is provided between the wall and the holding portion, and the lead wire is pushed into the gap to be held, and is drawn into the cooking device main body through the gap.

[0007]

In the above temperature control device, when the operation lever is gripped and operated left and right, the sliding member moves left and right. At this time, one end of the lead wire connected to the switch moves and deforms the curved shape of the lead wire, but the curved shape of the lead wire is maintained even if the sliding member moves in either direction. Further, one end of the curved portion is along the sliding member, and the other end is in a posture along the guide wall parallel to the sliding member, thereby preventing a partial deformation load from acting on the lead wire.
